CONTAINED IN EXHIBIT 99.1 TO THE COMPANY'S SECURITIES AND EXCHANGE COMMISSION
FILINGS.

ITEM 1. BUSINESS.

GENERAL

    ROHN Industries, Inc., formerly known as UNR Industries, Inc., ("ROHN" or
the "Company"), is a leading manufacturer and installer of infrastructure
products for the communications industry, including cellular, Personal
Communications Systems ("PCS"), Enhanced Specialized Mobile Radio ("ESMR"),
paging, radio and television broadcast, wireless cable, private microwave and
other telecommunications businesses. The Company's principal product lines are
tower structures and equipment enclosures. Although the Company has been
expanding its international business, it is primarily a domestic manufacturer,
and descriptions of market conditions relate to the domestic market. From 1995
to 1997, the Company's growth was primarily due to the growth of domestic
wireless communications systems, and the introduction and growth of its
equipment enclosures product line. While U.S. wireless capital expenditures
continued at an accelerated pace from late 1997 through the first half of 1999,
these expenditures were increasingly made in technological system improvements
rather than for additional cell site development. In addition, the development
of a new build-to-suit tower industry, along with local zoning requirements,
encouraged increased emphasis on co-location of existing and new cell sites,
further decreasing the total number of cell sites developed. These were
significant factors in the decreased revenues experienced by the Company during
1999. The Company believes it should benefit from the continued build-out of
wireless communication systems as capacity requirements increase with the growth
in both wireless voice and data communications, along with the growth of
infrastructure to support the Internet through wireless and fiber optic
transmission. It is anticipated that additional growth will be realized from the
build-to-suit industry, which erects and leases towers and shelters to wireless
carriers. Participants in this relatively new industry have acquired well over
20,000 towers from existing carriers, and anticipate constructing a significant
portion of the new towers expected to be built in the near future. These new
towers are expected to be significantly larger than towers that have been built
in previous years, but their capacity to hold more than one carrier, and in many
cases seven or eight carriers, will result in less tower density in areas of
high communication traffic.

    The Company's key products consist of self-supporting and guyed
(cable-supported) towers, equipment enclosures, steel and concrete poles,
concrete and fiberglass equipment enclosures, equipment cabinets, antenna mounts
and installation services. The Company also manufactures steel agricultural
products.

    The Company was organized as a Delaware corporation in 1979. In 1982, the
Company filed a voluntarily petition for reorganization under Chapter 11 of the
Federal Bankruptcy Code. Pursuant to a Plan of Reorganization accepted by the
Company's creditors and stockholders and confirmed by the Bankruptcy Court in
1989, the Company issued 42,404,847 shares of common stock to the UNR
Asbestos-Disease Claims Trust and unsecured creditors in full discharge of all
claims. The trust currently owns 29,348,051 shares of common stock representing
approximately 55% of the Company's currently outstanding shares of common stock.
In March 1997, the Company moved its principal executive offices from Chicago,
Illinois to Peoria, Illinois, and in December 1997, the Company changed its name
to ROHN Industries, Inc. The Company currently maintains its executive offices
and main tower manufacturing facility at 6718 West Plank Road, Peoria, Illinois
61604.

TELECOMMUNICATIONS EQUIPMENT MARKET

    The use of wireless telephones in the United States has shown rapid growth
in recent years, from about five million subscribers in 1990 to over 75 million
at the end of 1999. The number of cell sites has risen from about 6,000 in 1990
to over 85,000 today and is expected to grow by as many as 34,000 in the next
year. While co-located and rooftop cells sites will make up many of these new
cell sites, the remainder are expected to require a tower or pole and equipment
enclosure. Co-located and rooftop sites will require mounts and equipment
enclosures.

    Competition among wireless carriers is becoming increasingly intense,
lowering the average cost per minute for a wireless call to the point where a
wireless phone may become an economic alternative to a wireline phone. This cost
reduction may serve to further enhance the growth of wireless subscribers. In
addition, other new technologies such as broadband wireless provide
opportunities to serve the rapid growth of internet services by providing "last
mile" links from fiber-optic hubs to office buildings. New technologies are
continually being introduced to use available wireless spectrum as an
alternative to traditional copper wire. These new technologies often require the
use of towers, poles, mounts and equipment enclosures such as those manufactured
by the Company.

    Radio and Television broadcast is another market served by the Company.
Recent changes in FCC regulation and the introduction of high definition
television (HDTV) should provide additional opportunities for the Company, as
new antenna support structures may be required to support these new broadcasting
technologies. In November 1999, the Company announced the execution of a
contract with Central Missouri State University to construct a 2,000-foot HDTV
tower. This contract represents the Company's first entry into the ultra high
tower market as a result of the Company's commitment to the expanding tall tower
industry. The Company has enhanced its engineering, manufacturing and
installation capabilities to enable it to expand its sales in this market
segment.

    ROHN is also an active participant in the fiber optic network industry,
supplying shelters and site installation services to several of the major fiber
optic carriers in the United States. In 1999, the Company announced a major
contract to supply Peter Kiewit, Inc. with over 700 shelters during 1999 and
2000. As Internet usage results in increased demand for data-carrying capacity
over fiber optic lines, ROHN shelters will continue to provide secure housing
for valuable transmission equipment located in remote sites around the country.

    The Company also plans to continue to develop overseas markets through its
United States customers and through the establishment of strategic partnerships,
such as the relationship with Radiotronica announced in September 1999. See
"--International."

PRODUCTS

    TOWER STRUCTURES.  The Company manufactures many configurations of towers,
ranging from a 2,000-foot high tower to small antenna mounts. The Company's
principal tower product is the tubular self-supporting tower ranging in heights
up to 900 feet. The Company's towers are used across the world for television
broadcast, AM/FM radio broadcast, microwave, cellular telephone, PCS, radar,
surveillance camera mounts, solar power stations and weather stations. Included
within the Tower Structures segment are steel and concrete poles, generally used
where space is too limited to erect a tower, as is often the case in urban
areas, and antenna mounts that are hot-dipped galvanized to prevent corrosion.
Antenna mounts range from non-penetrating roof mounts that spread the balanced
weight of an antenna over a large area to mounts that concentrate weight for
compact installation. The Company also provides tower mounts, wall mounts for
corners or flat walls, square pole mounts, and standard roof mounts for flat or
sloped roofs. Approximately 71%, 63% and 68% of the Company's revenues were
attributable to sales in the Tower Structures segment for years 1999, 1998 and
1997, respectively.

    ENCLOSURES.  Secure housing of highly valuable electronic components and
power systems is a major concern for communications companies. The Company's
concrete enclosures are made of lightweight concrete with steel reinforcements
for added strength. The Company's fiberglass enclosures are made of laminated
fiberglass and are lightweight, portable, strong and secure. The Company also
markets a non-combustible enclosure for rooftop applications, manufactured with
a steel frame to meet strict fire codes. Equipment cabinets, made of lightweight
concrete or molded fiberglass for water and rust resistance, are designed as
maintenance-free structures for compact equipment installations. The

                                       3
<PAGE>
Enclosures segment accounted for approximately 29%, 37% and 32% of the Company's
revenues for years 1999, 1998 and 1997, respectively. Concrete structures
represent the largest part of the Company's Enclosures segment, generating more
than 79% of Enclosures segment revenues for years 1999, 1998 and 1997.

    See Note 19 to the Consolidated Financial Statements of the Company in Item
8 for additional financial information regarding the Company's business
segments.

PATENTS AND TRADEMARKS

    The Company has a number of patents and trademarks, none of which are
considered material to its operations.

SEASONALITY OF BUSINESS

    The operations of the Company are generally not subject to seasonal
fluctuations. However, in the past, the Company has seen disruptions in its
customer's ability to accept shipments due to unusual and prolonged
weather-related construction delays.

    The Company has periodically experienced and expects to continue to
experience significant fluctuations in its quarterly results. It is believed
that this quarterly fluctuation is due to the capital budgeting cycle of many of
its customers who often purchase a disproportionately higher share of the
Company's products at the end of the calendar year. It is expected that
fluctuations in quarterly results could become more significant in the future as
customers move to a more centralized purchasing environment and as the
consolidation of wireless communication service providers and build-to-suit
customers continue.

    The Company's working capital requirements do not vary significantly from
period to period.

INTERNATIONAL

    Foreign sales accounted for approximately $22.1 million, $12.1 million and
$10.2 million of the Company's revenues for years 1999, 1998 and 1997,
respectively. The Company has sold towers and other equipment in more than 55
countries and currently operates a sales and construction office in Mexico City.
In December 1997, the Company entered into an agreement with BrasilSat Harald
S.A. ("BrasilSat") of Curitiba, Brazil to form a corporate joint venture to
serve the telecommunications infrastructure industry in Brazil and South
America. The corporate joint venture began production of enclosures in late
1998. The corporate joint venture's operations were adversely affected by the
Brazilian economy in 1998 and early 1999. In September 1999, the Company sold
its interest in the joint venture to its joint venture partner BrasilSat. The
Company plans to develop other foreign markets through its United States
customers, who are investing in telecommunications on a global basis, and
through the continued establishment of partnerships and facilities in key
developing countries.

    In September 1999, the Company announced a joint marketing agreement with
Radiotronica, S.A., a Spanish multi-national firm which is one of the world's
largest turnkey telecommunications providers. Radiotronica currently operates in
Spain, Portugal, Morocco, and Latin America, where it has subsidiaries in
Argentina, Brazil, Chile, Columbia and Peru. As part of the agreement, the
Company and Radiotronica will cooperate in the development and construction of
the wireless telecommunications infrastructure in Latin America. The agreement
provides for a unified marketing and sales structure.

    Substantially all of the Company's foreign sales are negotiated, invoiced
and paid in United States dollars. Accordingly, although changes in exchange
rates do not affect the Company's revenue, they can influence the willingness of
customers to purchase the Company's products. Adverse effects from economic
instability similar to those experienced by BrasilSat in 1998 and early 1999 may
have an adverse effect on the Company's foreign sales.

    See Note 18 to the Consolidated Financial Statements of the Company in Item
8 for additional financial information.

CUSTOMERS AND BACKLOG

    The Company markets its products worldwide, through a variety of marketing
channels with different customer focuses. Domestically, the Company has 10
direct salespeople.

                                       4
<PAGE>
    For international sales efforts, the Company employs two salespeople who
concentrate on Mexico and Latin America. In addition, the Company utilizes two
key distributors and a variety of agents to cover the remainder of the world.

    The Company's backlog was approximately $93.0 million, $29.0 million and
$52.4 million at December 31, 1999, 1998 and 1997, respectively. The 1999
backlog includes a $40 million contract with the State of Pennsylvania for a
statewide radio communications project. It is anticipated that this turnkey
project will be substantially completed by the end of 2000. In 1999, one
customer accounted for approximately 11% of the Company's net sales. In 1998,
one customer accounted for approximately 13% of the Company's net sales. No
customer accounted for more than 10% of the Company's sales in 1997.

COMPETITION

    The telecommunications infrastructure industry is highly competitive. The
Company faces substantial competition in both the Tower Structures and
Enclosures segments of its business from established competitors, some of which
have greater financial, engineering, manufacturing, and marketing resources than
the Company. The Company's competitors can be expected to continue to improve
the design of their products, to introduce new products with competitive prices
and performance characteristics and to improve customer service. Competitive
pressures caused an erosion in operating margins in 1998 and early 1999, and
competitive pressures could necessitate further price reductions, adversely
affecting operating results in the future. The Company believes that it has
certain competitive advantages over its competitors, such as its broad
engineering flexibility and capability, its historic customer relationships, its
international relationships, its ability to retain a skilled workforce, and its
purchasing volume for raw materials. The Company can not be certain that it will
be able to maintain the competitive advantages it currently enjoys.

RAW MATERIALS

    The primary raw materials used by the Company to produce its products are
steel, zinc and concrete. These materials are currently readily available in the
marketplace. The Company is not dependent upon any single supplier for any
materials essential to its business or not otherwise commercially available. The
Company has been able to obtain an adequate supply of raw materials and does not
anticipate a shortage of raw materials. The Company's ability to continue to
acquire steel, zinc and concrete on favorable terms, however, may be adversely
affected by factors beyond its control. Because steel, zinc and concrete
constitute a significant portion of the Company's cost of goods sold, any
increase in price of such materials could have a material adverse impact on the
Company's gross profit margin.

EMPLOYEES

    As of December 31, 1999, the Company employed 654 people. Collective
bargaining agreements cover 322 employees at its facilities in Peoria and
Frankfort. The Company's union employees are members of the United Automobile,
Aerospace and Agricultural Implement Workers of America (UAW) in Peoria and the
Retail, Wholesale and Department Store Union (RWDSU) in Frankfort. The Company
considers its relations with its employees to be good.

    The Company's success depends to a significant degree upon the continued
contributions of key management, engineering, sales, marketing, customer
support, finance and manufacturing personnel. The loss of certain personnel
could have a material adverse effect on the Company and its operations. The
Company cannot be certain that these personnel will continue to be available to
the Company. In addition, the Company believes that its success depends on its
ability to attract additional qualified employees and that the failure to do so
could have a material adverse effect on the Company and its operations.

ENVIRONMENTAL MATTERS

    The Company employs some materials in its manufacturing processes, including
oils and solvents that are regulated by environmental laws. The Company has made
expenditures to comply with environmental laws and regulations, including
investigation and remediation of ground and water contamination, and expects to
continue to make such expenditures to comply with existing and future
requirements. While such expenditures have not had, and are not expected to
have, a material adverse effect on

                                       5
<PAGE>
the Company's financial condition or results of operations, there can be no
assurance that more stringent regulations or enforcement in the future will not
have such effects.

    In some cases, the Company has notified state or federal authorities of a
possible need to remedy sites it previously operated. The Company has also been
notified by various state and federal governmental authorities that they believe
it may be a "potentially responsible party" or otherwise have responsibility
with respect to clean-up obligations at certain hazardous and other waste
disposal sites which were not owned or operated by the Company. In several such
cases, the Company has entered into settlements with the relevant authorities or
other parties for immaterial amounts. In other cases, the Company is
participating in negotiations for settlement with the relevant authorities or
other parties or has notified the authorities that it denies liability for
clean-up obligations. The costs or liabilities the Company may incur with
respect to these sites are difficult to predict until the level of contamination
is determined. The Company, after consultation with legal counsel and
environmental experts, believes that the ultimate outcome with respect to all of
these sites will not have a material adverse effect on the Company's financial
condition or on its results of operations.

ITEM 2. PROPERTIES.

ITEM 3. LEGAL PROCEEDINGS.

    The Company is involved in various pending legal proceedings and claims
arising in the ordinary course of business, as well as claims arising from the
Company's disposition of certain Divisions in 1996. Although the outcome of such
proceedings and claims cannot be determined with certainty, the Company
believes, after consultation with legal counsel, that such proceedings and
claims, individually or in the aggregate, are not material to any of its
business, financial condition, or results of operations. See
"Business--Environmental Matters."

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

    No matters were submitted to a vote of the Company's security holders during

</TABLE>

    The decrease in sales in the Tower Structures segment was primarily the
result of a continued softness in the demand for the installation and erection
of towers within the Company's construction business. The decrease in sales in
the Enclosures segment was primarily due to a significant reduction in sales
volume to a provider of a high-speed broadband fiber optic network whose
buildout was completed in 1999. 1998 sales for the Enclosures segment were
significantly higher due to the significant volume of business with this same
provider of a high-speed broadband fiber optic network.

    International sales increased to $22.1 million in 1999 from $12.1 million in
1998, an increase of $10.0 million or 82.6%. This increase in international
sales is the result of the Company's efforts to increase international market
penetration, particularly in Mexico and the rest of Latin America.

    Many times, the Company's customers experience delays due to weather, zoning
approvals, and other similar circumstances, and request that the Company hold
their inventory. In these situations where the product is available for
shipment, and title has passed to the customer, the Company recognizes revenue
for its Tower Structures segment. Results of operations for the years ended
December 31, 1999 and 1998 include Tower Structures revenues of $2.4 million and
$4.2 million, respectively, related to product not yet shipped, but where the
previously-discussed earnings criteria had been met.

    The Enclosures segment differs from Tower Structures in that enclosures are
generally ordered by the customer in multiple units on a project basis and are
not necessarily site specific. Therefore, the revenue recognition policy for
enclosures, in addition to the requirements of the Tower Structures segment,
also requires that actual payment be received. Results of operations for the
years ended December 31, 1999 and 1998 include Enclosures revenues of
$4.9 million and $6.5 million, respectively, related to product not yet shipped,
but where the earnings criteria had been met.

    Gross profit for 1999 was $32.8 million versus $43.0 million in 1998, a
decrease of 23.7%. Gross profit margin was 23.1% in 1999 versus 24.7% for 1998.
The decrease in gross profit margin was

                                       10
<PAGE>
primarily attributable to non-recurring charges taken during the first half of
1999 totaling $1.8 million, of which $1.5 million related to a writedown of
inventory and $.3 million related to severance payments due to a reduction in
workforce. Without the impact of the non-recurring charges taken during the
first half of 1999, gross margin would have been $34.6 million or 24.4% of
sales. Gross profit margins for the Company's Tower Structures segment increased
from approximately 18% at the end of 1998 to 26% at the end of 1999. This
increase in gross margin was primarily the result of cost cutting measures
implemented in 1999, including the reduction of raw material costs. Gross profit
margins for the Company's Enclosure segment decreased from approximately 26% at
the end of 1998 to 18% at the end of 1999. This decrease in gross margin was
primarily the result of intense price competition for new orders received in
1999.

    In November 1999, the Company entered into a contract with the State of
Pennsylvania to supply and install communications towers/poles and/or enclosures
for a state-wide radio communications project. This contract could generate
approximately $40 million in revenues, and it is anticipated that this project
will be substantially completed by the end of 2000. Historically, margins on the
Company's installation business have been significantly lower than margins on
sales of its tower and enclosure products. Due to the large portion of the
contract which comprises installation and civil engineering work, it is
anticipated that the margins to be recognized on the State of Pennsylvania
contract will be significantly lower than the margins the Company has recently
achieved in its Tower Structures or Enclosures segment.

    Selling, general and administrative ("SG&A") expenses were $19.3 million in
1999 versus $18.8 million in 1998, an increase of $0.5 million, or 2.7%. As a
percentage of sales, SG&A expenses were 13.6% in 1999 and 10.8% in 1998. The
increase in SG&A expenses was primarily attributable to a charge for severance
payments of $.7 million taken in the second quarter of 1999 relating to a
reduction in workforce. Without this non-recurring charge, SG&A expense for 1999
would have been $18.6 million.

    The Company incurred other expenses of approximately $1.6 million related to
fees and expenses in connection with the proposed merger with PiRod
Holdings, Inc., which was terminated on March 30, 1999. These expenses were
recognized by the Company in the first quarter of 1999, resulting in an adverse
impact on earnings of approximately $.02 per share.

    The Company's effective tax rate for 1999 was 37.2% versus 37.9% in 1998.

    The equity loss of the corporate joint venture of $.36 million relates to
the Company's share of the operating losses for ROHN BrasilSat, as well as the
loss related to the sale of its joint venture interest. The Company accounted
for this corporate joint venture under the equity method until its disposition
in September 1999. Of the $.36 million loss recorded by the Company in 1999,
$.12 million represented the Company's share of the operating losses of the
entity and $.24 million of the loss was related to the sale of the Company's
interest in the joint venture. The operations of ROHN BrasilSat started in 1998.
The Company sold its 49% interest in the joint venture to its joint venture
partner in September 1999.

    Earnings per share (basic and diluted) were $0.14 in 1999 versus $0.27 in
1998. The decrease in earnings per share was primarily attributable to the
softness in demand for the Company's products in 1999, the non-recurring charges
of $2.5 million taken during the second quarter of 1999, and the charge of
$1.6 million taken during the first quarter of 1999 for the failed merger
transaction. The charges taken in the first half of 1999 related to the failed
merger, inventory writedown and severance payments reduced earnings per share
for 1999 by $.05 per share basic and diluted.

1998 COMPARED TO 1997

    Net sales for 1998 were $174.2 million compared to $158.1 million in 1997,
an increase of 10.2%. The increases in sales by business segment were as
follows.

    The increase in sales in the Tower Structures segment was primarily due to a
$1.0 million increase in sales in international markets as well as recapturing
market penetration domestically. The Company believes that the overall market
for tower products in 1998 was unchanged from 1997. One of the Company's
principal business objectives in 1998 was to reverse losses in market share
experienced in previous years. The Company's Enclosures segment benefited from a
wider range of applications for these products both within the communications
industry and outside the industry.

    In 1998, many of the Company's customers experienced delays and requested
that the Company hold their inventory. In circumstances where the product is
ready for shipment, the customer requests delayed shipment and risk of ownership
has passed to the customer, the Company recognizes revenue for its Tower
Structures segment. Results of operations for the year ended December 31, 1998,
included approximately $4.2 million of Tower Structures revenues related to
product that had not been shipped, but where the earnings criteria were met. No
such revenues were recorded in 1997, in accordance with generally accepted
accounting principles, because the revenue recognition criteria were not met.

    The Enclosures segment differs from the Tower Structures segment in that the
Enclosures are generally ordered by the customer in multiple units on a project
basis and are not necessarily site specific. Therefore, the revenue recognition
policy for enclosures, in addition to the requirements for the Tower Structures
segment, also requires that actual payment be received. Results of operations
for the year ended December 31, 1998, included approximately $6.5 million of
Enclosures revenues related to product that had not been shipped, but where the
earnings criteria was met. No such revenues were recorded in 1997, in accordance
with generally accepted accounting principles, because the revenue recognition
criteria were not met.

    Gross profit for 1998 was $43.0 million versus $47.0 million in 1997, a
decrease of 8.5%. Gross profit margin was 24.7% in 1998 versus 29.7% for 1997.
The 5% decrease was attributable to a significant decrease in gross profit
margins for the Company's tower products. This gross profit margin deterioration
was experienced primarily in the last two quarters of 1998. Significant
industry-wide pricing pressure was experienced as certain competitors lowered
prices and demand remained flat during the year. In addition, the Company
experienced increases in production costs related to annual purchasing
commitments for its primary raw materials such as steel and increased operating
costs of its new galvanizing facility which was brought on-line during the
latter half of 1997.

    SG&A expenses were $18.8 million in 1998 versus $17.1 million in 1997, an
increase of $1.7 million, or 9.9%. As a percentage of sales, SG&A expenses were
10.8% in both 1998 and 1997. The increase in SG&A expenses was primarily
attributable to an increase in sales and marketing costs. The Company invested
in additional sales, project management and customer service personnel and
enhanced sales tools such as catalogs and trade shows to gain sales momentum in
the domestic market place. Also, the Company increased its spending to improve
its worldwide market presence.

    During the third quarter of 1997, the Company's Board of Directors approved
a special charge of $3.4 million ($2.1 million after tax or $0.04 per share) to
cover the costs of a restructuring program. The restructuring charge was related
to cost cutting measures including early retirement costs, other workforce
reductions, and expenses associated with the development and implementation of
this program. The provision for the reduction in workforce included severance
and other benefits for approximately 25 employees, the majority of whom were
based in Peoria, Illinois and Frankfort, Indiana. During 1997, cash expenditures
of $1.9 million were charged against the reserve. Approximately $1.1 million of
expenses were charged against the reserve in 1998, with the remaining balance
expended in 1999.

    The Company's 1998 effective tax rate was 37.9% versus 37.1% in 1997. This
increase in the effective tax rate was primarily due to the non-recurring nature
of certain adjustments made in 1997. These adjustments were recorded by the
Company when it finalized its 1996 return in late 1997.

    The equity loss of the corporate joint venture of $.5 million in 1998
related to the Company's share of the start-up losses for ROHN BrasilSat. The
operations of ROHN BrasilSat began in 1998.

    Earnings per share (basic and diluted) were $0.27 in 1998 versus $0.36 in
1997. The decrease in earnings per share was primarily attributable to the
significant decrease in gross profit margin experienced by the Tower Structures
segment in 1998. The 1997 earnings per share included $0.05 per share

                                       12
<PAGE>
gain on the sale of an investment in a non-related business and a $0.04 per
share loss related to the restructuring charge.

    The Company reduced in size due to the sale of Leavitt Tube, Unarco
Commercial Products, UNR Home Products and Real Time Solutions, Inc. in 1996,
and the closing in 1997 of the Company's former corporate office in Chicago, IL.
In 1998, the Company implemented a thorough review of its recorded reserves and
discovered that reserves for postretirement benefits other than pensions had not
been properly provided for in accordance with Statement of Financial Accounting
Standards No. 106, "Employers' Accounting for Postretirement Benefits Other Than
Pensions." As of January 1, 1998, the Company had an unfunded accumulated
postretirement benefit obligation of $3.5 million and an unamortized net
transition obligation of $1.8 million, resulting in an accrual requirement of
$1.7 million at the beginning of the year. The Company recorded a charge in 1998
to establish a postretirement benefit liability of approximately $2.2 million as
of December 31, 1998. Also, in connection with the Company's thorough review of
its recorded reserves, it was determined that there were excess reserves of
approximately $2.4 million related to insurance, accounts receivable and other
miscellaneous reserves that were not material to the prior year consolidated
financial statements. These excess reserves were reversed in 1998. Due to the
immateriality of the postretirement benefit charges to the consolidated
financial statements of the Company from 1993 through 1997, no restatement was
made.

LIQUIDITY AND CAPITAL RESOURCES

    The following table sets forth selected information concerning the Company's
financial condition:

</TABLE>

    The Company's working capital was $61.8 million at December 31, 1999
compared to $50.8 million at December 31, 1998, an increase of $11.0 million.
This increase in working capital primarily reflects an increase in cash and
accounts receivable related to increased sales at year end.

    At December 31, 1999, the Company had aggregate indebtedness of
$10.2 million. The Company's outstanding indebtedness was related to mortgage
notes payable and capital leases.

    The Company does not have any material capital commitments. The Company
expects that it will meet its ongoing working capital and capital expenditure
requirements from operating cash flows. In addition, the Company believes that
its strong balance sheet allows it substantial financial flexibility.

INFLATION

    Inflation has not had a material effect on the Company's business or results
of operations.

SEASONALITY AND QUARTERLY RESULTS OF OPERATIONS

    The operations of the Company are generally not subject to seasonal
fluctuations. However, in the past, the Company has seen disruptions in its
customer's ability to accept shipments due to unusual and prolonged
weather-related construction delays.

    The Company has periodically experienced and expects to continue to
experience significant fluctuations in its quarterly results. The Company
believes that this quarterly fluctuation is due to the capital budgeting cycle
of many of its customers who often purchase a disproportionately higher share of
the Company's products at the end of the calendar year. It is expected that
fluctuations in quarterly results could become more significant in the future as
customers move to a more centralized purchasing environment and as the
consolidation of wireless communication service providers and build-to-suit
customers continues.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, Statement of Financial Accounting Standards ("SFAS") No. 133,
"ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES," was issued. This
standard establishes accounting and

                                       13
<PAGE>
reporting standards for derivative instruments and hedging activities. It
requires that an entity recognize all derivatives as either assets or
liabilities in the balance sheet and measure those instruments at fair value.
Changes in the fair value of derivatives are recorded in earnings or other
comprehensive income, based on whether the instrument is designated as part of a
hedge transaction. The Company adopted SFAS No. 133 in 1999. The adoption of
this statement did not have a material effect on the Company's results of
operations or financial condition as the Company historically does not enter
into these types of transactions in the normal course of business.

YEAR 2000 COMPLIANCE

    Historically, certain computer programs were written using two digits rather
than four to define the applicable year. Accordingly, a company's software may
have recognized a date using "00" as the year 1900 rather than the year 2000,
which could result in computer system failures or miscalculations, commonly
referred to as the Year 2000 ("Y2K") issue. The Y2K issue could have arisen at
any point in the Company's supply, manufacturing, processing, distribution and
financial chains. Incomplete or untimely resolution of the Y2K issue by the
Company, key suppliers, customers and other parties could have had a material
adverse effect on the Company's results of operations, financial condition and
cash flows.

    The aggregate cost of the Company's Y2K efforts was approximately
$4.7 million. Approximately $4.5 million of these costs were related to the
acquisition of new computer systems which have been capitalized, with the
remainder being funded through operating cash flows. The Company incurred Y2K
costs of approximately $0.1 million in 1999. The Company believes material
implications and risks related to Year 2000 have expired and, therefore, does
not anticipate experiencing any additional effects related to this issue. The
Company did not experience a significant increase in customer demand for
products as a result of Year 2000, nor did it experience any problems with its
key vendors.

SUBSEQUENT EVENTS

    On January 7, 2000, the Company announced the resignation of Maureen B.
Bellantoni as Executive Vice President and Chief Financial Officer of the
Company, effective February 4, 2000. Ms. Bellantoni assumed the position of
Chief Financial Officer at Burger King North America. Daniel J. Pallat has been
hired as interim CFO of ROHN until a permanent replacement for Maureen
Bellantoni is employed. Mr. Pallat is a partner with Tatum CFO Partners, LLP, a
national organization of senior financial executives that provides CFO services
to businesses on a permanent or transitional basis. Prior to joining Tatum, he
served in financial and operating management positions from CFO to Group Vice
President with several public companies.

    On January 19, 2000, the Company announced the retirement of Richard L. Rohn
as Vice President--Equipment Enclosures, effective March 6, 2000. The Company
will record a charge in 2000 related to Mr. Rohn's retirement, the amount of
which has not yet been determined.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

    The Company has limited exposure to market rate sensitivity and any adverse
impacts realized would not be material to its financial results. The principal
market risks to which the Company is currently exposed to or may be exposed to
during 2000 or beyond are changes in interest rates and foreign currency
exchange rates.

    The Company currently manages its exposure to changes in interest rates by
utilizing primarily all fixed rate debt. In the future, it is expected that if
additional debt is incurred, the Company would manage its exposure to changes in
interest rates by optimizing the use of variable-rate and fixed-rate debt and by
utilizing interest rate swaps. International sales, which accounted for 15.6% of
net sales in 1999, are concentrated principally in Latin America. In the future,
the Company expects that if it experiences significant growth in its
international sales activity, the Company would manage its exposure to changes
in exchange rates by borrowing in foreign currencies and by utilizing either
cross-currency swaps or forward contracts. Such swaps or forward contracts would
be entered into for periods consistent with related underlying exposures and
would not constitute positions independent of those exposures. The Company does
not expect to enter into contracts for speculative purposes.

1. NATURE OF OPERATIONS

    ROHN Industries, Inc. and subsidiaries ("ROHN" or the "Company")
manufactures and installs towers, poles, mounts and related accessories used
principally to support telecommunications antennae for wireless communications,
such as cellular telephone, personal communications systems ("PCS"), private
microwave, commercial and amateur broadcasting and home television. The Company
also produces equipment enclosures and cabinets of concrete and fiberglass to
house electronic telecommunications equipment. The Company has manufacturing
facilities in Peoria, Illinois (towers and poles), Bessemer, Alabama (equipment
enclosures), and Frankfort, Indiana (towers, tower component, mounts and
agricultural products). The Company's products are sold direct to customers and
through the use of distributors throughout the United States and in
international markets.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The significant accounting policies followed by the Company are described
below:

PRINCIPLES OF CONSOLIDATION

    The financial statements include the consolidated accounts of the Company
and its subsidiaries. All significant intercompany transactions have been
eliminated in consolidation. The Company accounted for its 49% interest in ROHN
BrasilSat, a corporate joint venture in Brazil, under the equity method until
its disposition in September 1999.

REVENUE RECOGNITION

    The Company's products are manufactured according to stringent customer
specifications and engineering design, and are available for immediate delivery
according to the schedule requested by the customer. Revenue is generally
recognized when product is shipped. However, the Company recognizes revenue for
its Tower Structures segment prior to the time a product is shipped if each of
the following conditions are met:

1)  The risks of ownership have passed to the customer;

2)  The customer has a fixed commitment to purchase the goods;

3)  The customer, not the Company, has requested that the shipment of the
    product be delayed and that the transaction be on a bill and hold basis;

4)  There is a fixed schedule for delivery of the product;

5)  The Company has not retained any specific performance obligations with
    respect to the product such that the earnings process is not complete;

6)  The ordered product has been segregated from the Company's inventory and is
    not subject to being used to fill other orders; and

7)  The product is complete and ready for shipment.

    Many times, the Company's customers experience delays due to weather, zoning
approvals, and other similar circumstances, and request that the Company hold
their inventory. In these situations where the product is available for
shipment, and title has passed to the customer, the Company recognizes revenue
for its Tower Structures segment. Results of operations for the years ended
December 31, 1999 and 1998 include Tower Structures revenues of $2.4 million and
$4.2 million, respectively, related to product not yet shipped, but where the
previously-discussed earnings criteria had been met. No such revenues were
recorded in 1997, in accordance with generally accepted accounting principles,
as the revenue recognition criteria had not been met.

    The Enclosures segment differs from Tower Structures in that enclosures are
generally ordered by the customer in multiple units on a project basis and are
not necessarily site specific. Therefore, the revenue recognition policy for
enclosures, in addition to the requirements of the Tower Structures segment,
also requires that actual payment be received. Results of operations for the
years ended December 31, 1999 and 1998 include Enclosures revenues of
$4.9 million and $6.5 million, respectively, related to product not yet shipped,
but where the earnings criteria had been met. No such revenues were

                                       20
<PAGE>
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
recorded in 1997, in accordance with generally accepted accounting principles,
as the revenue recognition criteria had not been met.

CASH EQUIVALENTS

    The Company considers all highly liquid short-term investments purchased
with a maturity of three months or less and all treasury bills to be cash
equivalents. Cash equivalents are carried at cost which approximates market
value.

INVENTORIES

    Inventories are stated at the lower of cost or market. Cost is determined
using the first-in, first-out (FIFO) method. Inventory costs include material,
labor and factory overhead. Obsolete or unsalable inventories are reflected at
their estimated net realizable values.

    Total inventories in 1999 and 1998 included the following classifications
(in thousands):

</TABLE>

PLANT AND EQUIPMENT

    Land, buildings and equipment are carried at cost. Expenditures for
maintenance and repairs are charged directly against income and major
renewals/betterments are capitalized. When properties are retired or otherwise
disposed of, the original cost and accumulated depreciation are removed from the
respective accounts and the profit or loss resulting from the disposal is
reflected in income.

    The Company provides for depreciation of plant and equipment over the
estimated useful lives of the assets (buildings--20 to 40 years; machinery and
equipment--3 to 15 years). Depreciation is generally provided on the
straight-line method for financial reporting purposes and on accelerated methods
for tax purposes.

INCOME TAXES

    Under Statement of Financial Accounting Standards No. 109, "Accounting for
Income Taxes" (SFAS 109), the Company recognizes deferred tax liabilities and
assets for the expected future tax consequences of events that have been
recognized in the Company's financial statements or tax returns.

    Total income tax expense for the years ended December 31, 1999, 1998, and
1997, was allocated as follows (in thousands):

NET INCOME PER SHARE

    Basic earnings per share were computed by dividing net income by the
weighted average number of shares outstanding during the year. Diluted earnings
per share were calculated by including the effect of all dilutive securities.
For the years ended December 31, 1999, 1998 and 1997, the effect of potentially
dilutive stock options was approximately 346,000, 5,000 and 83,000,
respectively. The Company had additional outstanding stock options of 745,000 as
of December 31, 1999, which were not included in the computation of diluted
earnings per share because the options' exercise price was greater than the
average market price of the common shares.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements as well as the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

RECLASSIFICATIONS

    Certain prior year amounts have been reclassified to conform with the
current year presentation.

NEW ACCOUNTING STANDARDS

    In 1998, the Company adopted SFAS No. 130, "REPORTING COMPREHENSIVE INCOME,"
SFAS No. 131, "DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED
INFORMATION," and SFAS No. 132, "EMPLOYERS' DISCLOSURES ABOUT PENSIONS AND OTHER
POSTRETIREMENT BENEFITS." These statements expanded or modified disclosures and
had no material impact on the Company's results of operations, financial
condition or cash flows.

    SFAS No. 130 established standards for reporting and display of
comprehensive income, its components and accumulated balances. Comprehensive
income is defined to include all changes in equity except those resulting from
investments by owners and distributions to owners. Among other disclosures, SFAS
No. 130 requires that all items that are required to be recognized under current
accounting standards as components of comprehensive income be reported in a
financial statement that is displayed in the same prominence as other financial
statements. The Company has no differences between reported net income and
comprehensive income.

                                       22
<PAGE>
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    SFAS No. 131 established standards for the way that public enterprises
report information about operating segments in annual financial statements and
require reporting of selected information about operating segments in interim
financial statements issued to the public. It also established standards for
disclosures regarding products and services, geographic areas, and major
customers. SFAS No. 131 defines operating segments as components of an
enterprise about which separate financial information is available that is
evaluated regularly by the chief operating decision maker in deciding how to
allocate resources and in assessing performance. The company maintains two
segments: Tower Structures and Enclosures.

    SFAS No. 132 changed certain disclosure requirements for pensions and other
postretirement benefits.

    In June 1998, SFAS No. 133, "ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND
HEDGING ACTIVITIES" was issued. This standard establishes accounting and
reporting standards for derivative instruments and hedging activities. It
requires that an entity recognize all derivatives as either assets or
liabilities in the balance sheet and measure those instruments at fair value.
Changes in the fair value of derivatives are recorded in earnings or other
comprehensive income, based on whether the instrument is designated as part of a
hedge transaction. The Company adopted SFAS No. 133 in 1999. The adoption of
this statement did not have a material effect on the Company's results of
operations or financial condition, as the Company historically does not enter
into these types of transactions in the normal course of business.

7. PENSION, PROFIT SHARING AND POSTRETIREMENT BENEFITS

GENERAL

    The Company has defined benefit and/or defined contribution retirement plans
covering substantially all of its employees. Included in these plans are certain
union sponsored plans to which the Company makes annual contributions equal to
the amounts accrued. The total pension expense for union sponsored plans for
1999, 1998, and 1997, was $785,000, $856,000, and $740,000, respectively. The
Company has one trustee-administered profit sharing plan covering all eligible
employees in its Enclosures segment, located in Bessemer, Alabama. Discretionary
contributions of $227,000, $165,000, and $240,000, were charged to expense in
1999, 1998, and 1997, respectively. Total pension expense for Company-sponsored
plans for 1999, 1998, and 1997 was $148,000, $20,000, and $300,000,
respectively.

PENSION PLAN

    The Company's non-union employees of its Tower Structures segment in Peoria,
Illinois and Frankfort, Indiana, are covered by a noncontributory defined
benefit pension plan. Plan benefits are generally based on years of service and
employee compensation during the last years of employment. Benefits are paid
from funds previously provided to trustees for those plans. Actuarial
assumptions and provisions are reviewed regularly by the Company and its
independent actuary to ensure that plan assets will be adequate to provide
pension benefits. Plan assets consist primarily of investments in equities,
fixed income securities and money market funds.

    Pension expense includes the following components (in thousands):

RETIREMENT PLAN

    The Company has a 401(k) Tax Deferred Savings Plan for the benefit of
non-union employees. After one year of continuous service, the Company matches
25% of employee contributions up to 12% of an employee's compensation and
subject to the limits allowed by the Internal Revenue Service. The matching
contribution made by the Company was $188,000 in 1999, $176,000 in 1998 and
$173,000 in 1997.

RETIREE BENEFITS

    The Company provides certain postretirement healthcare benefits to both the

7. PENSION, PROFIT SHARING AND POSTRETIREMENT BENEFITS (CONTINUED)
    The discount rate used to determine the accumulated postretirement
healthcare benefit obligation was 7.5% and 7.0% in 1999 and 1998, respectively.
The assumed healthcare cost trend rate used to measure the accumulated
postretirement benefit obligation was 9.0% in 1999, declining to 5.5% over a
period of 8 years and continuing at 5.5% thereafter. A one percentage point
increase in the assumed healthcare cost trend would have increased the
accumulated postretirement benefit obligation by $525,390 and $590,000 for 1999
and 1998, respectively, and the postretirement benefit expense by $63,170 and
$68,000 for 1999 and 1998, respectively. A one percentage point decrease in the
assumed healthcare cost trend would have reduced the accumulated postretirement
benefit obligation by $506,770 and $527,000 for 1999 and 1998, respectively, and
the postretirement benefit expense by $61,295 and $62,000 for 1999 and 1998,
respectively.

    The current portion of non-pension post retirement healthcare benefits
included in accrued liabilities was approximately $200,000 and $126,000 at
December 31, 1999 and 1998, respectively.

    The Company has reduced in size due to the sale of Leavitt Tube, Unarco
Commercial Products, UNR Home Products and Real Time Solutions, Inc. in 1996,
and the closing in 1997 of the Company's former corporate office located in
Chicago, Illinois. In 1998, the Company implemented a thorough review of its
recorded reserves and discovered that reserves for postretirement benefits other
than pensions had not been properly provided for in accordance with Statement of
Financial Accounting Standards No. 106, "EMPLOYERS' ACCOUNTING FOR
POSTRETIREMENT BENEFITS OTHER THAN PENSIONS." As of January 1, 1998, the Company
had an unfunded accumulated postretirement benefit obligation of $3.5 million
and an unamortized net transition obligation of $1.8 million, resulting in an
accrual requirement of $1.7 million at the beginning of the year. The Company
recorded a charge in 1998 to establish a postretirement benefit liability of
approximately $2.2 million as of December 31, 1998. Also, in connection with the
Company's thorough review of its recorded reserves, it was determined that there
were excess reserves of approximately $2.4 million related to insurance,
accounts receivable and other miscellaneous reserves that were not material to
the prior year consolidated financial statements. These excess reserves were
reversed in 1998. Due to the immateriality of the postretirement benefit charges
to the consolidated financial statements of the Company from 1993 through 1997,
no restatement was made.

8. LITIGATION

    The Company is involved in various pending legal proceedings and claims
arising in the normal course of its business. Although the outcome of such
proceedings and claims cannot be determined with certainty, the Company
believes, after consultation with counsel, that such proceedings and claims,
individually or in the aggregate, are not material to either its business,
financial condition, or results of operations.

9. LEASES

    The Company leases certain of its facilities and equipment under operating
leases or capital leases, as defined by SFAS No. 13. The Company's property
under capital leases, which is included in plant and equipment, consists of
$2.4 million at December 31, 1999 and $2.7 million at December 31, 1998.

    Future minimum payments for operating leases at December 31, 1999 are
$339,000 in 2000, $312,000 in 2001, $240,000 in 2002, $119,000 in 2003, $82,000
in 2004 and $71,000 thereafter. Rental expense under operating leases was
approximately $476,000 in 1999, $493,000 in 1998, and $469,000 in 1997.

("1994 Plan") and the 1999 Stock Option Plan ("1999 Plan").

    The Executive Plan was approved by the shareholders of the Company on
July 12, 1990. This plan provides for granting of non-qualified and incentive
stock options, and reserves for the issuance of up to 2,500,000 authorized but
unissued shares of common stock. Options granted under this plan are exercisable
at a price equal to the fair market value at the date of grant and expire in ten
years from the date of grant. At December 31, 1999, 27,000 common shares were
available for grant under this plan. At December 31, 1999, 1,126,000 options

under this plan are exercisable at a price equal to the fair market value at the
date of grant, reduced by the amount of any "Extraordinary Dividend" made after
the date of grant, and expire in five years from the date of grant. Each option
is exercisable upon the attainment of certain stock price thresholds, adjusted
for extraordinary dividends, or 54 months, whichever comes earlier. At
December 31, 1999, 55,000 common shares were available for grant under this
plan. At December 31, 1999, no options were outstanding under this plan.

</TABLE>

    The 2,226,000 options outstanding at December 31, 1999 had an exercise price
between $1.281 and $7.75 with a weighted-average exercise price of $3.164 and a
weighted average remaining contractual life of 7.93 years. The fair value of
each option grant is estimated on the date of grant using the Black-Scholes
option pricing model with the following weighted-average assumptions used for
the option grants in 1999: risk-free interest rate of 6.01 percent, expected
dividend yield of 0.00 percent, expected life of 10.0 years, and expected
volatility of 44.81 percent. The following weighted-average assumptions were
used for the options granted in 1998: risk-free interest rate of 5.63 percent,
expected dividend yield of 1.79 percent, expected life of 10.0 years, and
expected volatility of 36.81 percent. The following weighted-average assumptions
were used for the options granted in 1997: risk-free interest rate of
6.45 percent, expected dividend yield of 1.72 percent, expected life of
5.0 years, and expected volatility of 37.18 percent.

13. RESTRICTED STOCK PLAN

    The Restricted Stock Plan was approved by the shareholders of the Company on
July 30, 1992. The Plan provides for the granting of restricted stock to certain
key employees and reserves for issuance of 1,000,000 shares of common stock.

    The Company had 220,840, 388,990 and 242,048 shares of restricted stock
outstanding at December 31, 1999, 1998 and 1997, respectively. Of the current
shares outstanding, 50,000 were awarded to Brian B. Pemberton in connection with
his employment agreement and 170,840 shares were issued to Brian B. Pemberton
and other key employees of the Company. These shares have the same dividend and
voting rights as other common stock. Restricted stock is considered to be
currently issued and outstanding. The cost of the restricted stock, determined
as the fair market value of the shares at the date of grant, is expensed ratably
over a three to five-year vesting period. Such expense amounted to $487,000 in
1999; $526,000 in 1998, and $1,153,000 in 1997.

14. DIRECTOR'S STOCK OWNERSHIP PLAN

    The Company has a stock ownership plan for non-employee directors, the
Amended and Restated ROHN Industries, Inc., 1994 Nonemployee Director Stock
Ownership Plan (the "Director Plan"), which was approved by the stockholders of
the Company in 1994. A total of 200,000 shares of the Company's common stock was
initially reserved for issuance under the Director Plan. The Director Plan
initially allowed each non-employee director to elect to receive all or a part
of such director's annual retainer fee, which would otherwise be paid in cash,
in shares of restricted stock held in custody by the Company. The Director Plan
was amended by the Board of Directors on May 18, 1999, to require that directors
receive their entire annual retainer fee in the form of "Stock Units", which
represent the right to receive shares of common stock upon the earliest of the
fifth anniversary of the date on which the Stock Units are granted, the
termination of the participant's service as a director, or a change of control.

15. STOCKHOLDERS' EQUITY

    On September 24, 1990, the Company announced that its Board of Directors had
authorized the acquisition, through both negotiated transactions involving large
blocks and open-market purchases, of up to 1.5 million shares of its common
stock to be held as treasury shares and be available to meet

                                       30
<PAGE>
requirements of its Key Executives' Stock Option Plan. As of December 31, 1999
and 1998, 1,133,565 shares have been purchased, respectively.

    On December 29, 1997, the Company paid a dividend of $0.10 per share to
stockholders of record as of the close of business on December 15, 1997.

16. RESTRUCTURING

    During the third quarter of 1997, the Company recorded a restructuring
charge of $3.4 million related to cost-cutting measures including early
retirement costs, work force reductions, and expenses associated with the
development and implementation of this program. The provision for the reduction
in workforce included severance and other benefits for approximately 25
employees, the majority of whom were based in Peoria, Illinois and Frankfort,
Indiana.

    During 1997, cash expenditures of $1.9 million were charged against the
reserve. Approximately $1.1 million of expenses were charged against the reserve
in 1998. The Company spent the remaining $0.4 million of the restructuring
reserve in 1999.

17. RELATED PARTY TRANSACTIONS

    The Company held three notes receivable for a total of $2,300,000 from
executive officers of the Company which were paid in full by the executive
officers during 1997 by transferring 309,000 shares of common stock to the
Company. These notes were related to the 1994 Executive Stock Purchase Plan
approved by shareholders of the Company on November 1, 1994. Under the Plan,
executive officers purchased 1,650,000 shares of common stock from the Company,
at the then fair market value. Shares were paid for in cash in the amount of the
par value of the stock and the balance in promissory notes due in three years.
The notes were interest free (although interest was imputed for tax purposes),
except in the event a participant resigned from the Company, was terminated for
cause or, if the stock was sold within three years, the notes would become due
and interest at the applicable federal rate was applied retroactively from the
date of the notes.

18. INVESTMENT IN CORPORATE JOINT VENTURE

    In December 1997, the Company formed a corporate joint venture with
BrasilSat Harald, S.A., Brazil's largest tower manufacturer and installer, to
serve the growing telecommunications infrastructure industry in Brazil and the
rest of South America. In September 1999, after re-evaluating its investment,
the Company sold its 49% in ROHN BrasilSat to its joint venture partner,
BrasilSat Harald, S.A.

    ROHN accounted for the corporate joint venture under the equity method until
its disposition in September 1999. The Company recorded a loss of approximately
$355,000 in 1999 arising out of the corporate joint venture, of which $120,000
represented the Company's share of the operating losses of the joint venture and
$235,000 of the loss was related to the sale of the Company's interest in the
joint venture. The Company's investment in ROHN BrasilSat amounted to $0 and
$3,129,000 at December 31, 1999, and 1998, respectively. There was no investment
in ROHN BrasilSat in 1997. The Company recorded a loss of $540,000 for the year
ended December 31, 1998, which represented the Company's share of the start-up
losses.

19. BUSINESS SEGMENT INFORMATION

    The Company operates in two business segments: Tower Structures and
Enclosures. The segments are managed as strategic business units due to their
distinct manufacturing processes and potential end-user application. The Tower
Structures segment includes manufacturing plants in Peoria, Illinois and
Frankfort, Indiana, as well as a world-wide sales, marketing and distribution
effort. The Enclosures segment includes a manufacturing plant in Bessemer,
Alabama and has a sales, marketing and distribution effort separate from the
Tower Structures segment's sales and marketing resources.

    Accounting policies for measuring segment assets and earnings before
interest and taxes are substantially consistent with those described in Note 2.
The Company evaluates segment performance

                                       31

based on earnings before interest and taxes. Transfers between segments, which
are not material in nature, are recorded at cost.

(2) Includes equity investment in Brazil of $3,129.

    In 1999, the Tower Structures segment had one customer that accounted for
approximately 16% of total segment revenues and 11% of consolidated net sales.
The Enclosures segment had two customers that accounted for 24% of total segment
revenue, or 7% of consolidated net sales. In 1998, the Tower Structures segment
had one customer that accounted for approximately 13% of total segment revenues.
The Enclosures segment had four customers that accounted for 65% of total
segment revenue with one customer at 35% of total segment revenues, or 13% of
consolidated net sales. In 1997, no one customer accounted for more than 10% of
the Company's sales.

    Revenues and long-lived assets are related to U.S. operations, except for
Mexico, which had revenues of approximately $3.9 million, $0.9 million and
$0.5 million for the years ended December 31, 1999, 1998 and 1997, respectively,
and long-lived assets of $60,000, $50,000 and $10,000 as of December 31, 1999,
1998 and 1997, respectively.

20. EXPORT SALES

    Export sales for the years ended December 31, 1999, 1998, and 1997 were
$22.1 million, $12.1 million, and $10.2 million, respectively.

21. COMMITMENTS AND CONTINGENCIES

    From time to time, the Company becomes party to various claims and legal
actions arising during the ordinary course of business. Management believes that
the Company's cost and any potential judgments resulting from such claims and
actions would be covered by the Company's product liability insurance, except
for deductible limits and self-insured retention. The Company intends to defend
such claims and actions in cooperation with its insurers. It is management's
opinion that, in any event, their outcome would not have a material adverse
effect on the Company's financial position or results of operations.

                                       32
<PAGE>
    The Company employs some materials in its manufacturing processes, including
oils and solvents that are regulated by environmental laws. The Company has made
expenditures to comply with environmental laws and regulations, including
investigation and remediation of ground and water contamination, and expects to
continue to make such expenditures to comply with existing and future
requirements. While such expenditures have not had, and are not expected to
have, a material adverse effect on the Company's financial condition or results
of operations, there can be no assurance that more stringent regulations or
enforcement in the future will not have such effects.

    In some cases, the Company has notified state or federal authorities of a
possible need to remedy sites it previously operated. The Company has also been
notified by various state and federal governmental authorities that they believe
it may be a "potentially responsible party" or otherwise have responsibility
with respect to clean-up obligations at certain hazardous and other waste
disposal sites which were not owned or operated by the Company. In several such
cases, the Company has entered into settlements with the relevant authorities or
other parties for immaterial amounts. In other cases, the Company is
participating in negotiations for settlement with the relevant authorities or
other parties or has notified the authorities that it denies liability for
clean-up obligations. The costs or liabilities the Company may incur with
respect to these sites are difficult to predict until the level of contamination
is determined. The Company, after consultation with legal counsel and
environmental experts, believes that the ultimate outcome with respect to all of
these sites will not have a material adverse effect on the Company's financial
condition or on its results of operations.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

TO THE STOCKHOLDERS AND BOARD OF DIRECTORS OF
ROHN INDUSTRIES, INC.:

    We have audited the accompanying consolidated balance sheets of ROHN
Industries, Inc. (a Delaware corporation) and Subsidiaries as of December 31,
1999 and 1998, and the related consolidated statements of income, stockholders'
equity and cash flows for each of the three years in the period ended
December 31, 1999. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

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

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of ROHN
Industries, Inc. and Subsidiaries as of December 31, 1999 and 1998, and the
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1999 in conformity with generally accepted accounting
principles.

       REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SUPPLEMENTAL SCHEDULE

To the Stockholders and Board of Directors of ROHN Industries, Inc.:

    We have audited in accordance with generally accepted auditing standards,
the consolidated financial statements of ROHN Industries, Inc. and subsidiaries
included in this Form 10-K, and have issued our report thereon dated
February 16, 2000. Our audit was made for the purpose of forming an opinion on
the basic consolidated financial statements taken as a whole. The supplemental
Allowance for Doubtful Accounts Schedule Included in Part IV, Item 14(d) is the
responsibility of the Company's management and is presented for purposes of
complying with the Securities and Exchange Commission's rules and is not part of
the basic consolidated financial statements. This schedule has been subjected to
the auditing procedures applied in the audit of the basic consolidated financial
statements and, in our opinion, fairly states in all material respects the
financial data required to be set forth therein in relation to the basic
consolidated financial statements taken as a whole.

Meetings of stockholders for any other purpose may be held at such time and

                  SECTION 3. ADVANCE NOTICE PROVISIONS FOR BUSINESS TO BE
TRANSACTED AT A MEETING. For business properly to be brought before any meeting
of stockholders by a stockholder, the stockholder must have given timely notice

the principal executive offices of the corporation not less than 30 days nor
more

<PAGE>

than 60 days prior to the date of the meeting; provided, however, that in

of the meeting is given or made to stockholders, for such notice by the
stockholder to be timely, it must be so received prior to the date of the
meeting and not later than the close of business on the tenth day following the
day on which such notice of the date of the meeting was mailed or such public
disclosure was made. To be in proper written form, a stockholder's notice to the

be brought before the meeting and the reasons for conducting such business at
the meeting; (ii) the name and address, as they appear on the corporation's

stockholder in such business. The chairman of the meeting shall have the sole
authority to determine whether business was properly brought before the meeting
in accordance with the provisions of this Section 3 and, if the chairman of the

or she shall so declare to the meeting, and any such business not properly
brought before the meeting shall not be transacted.

meeting shall be given to each stockholder entitled to vote at such meeting not
less than ten nor more than sixty days before the date of the meeting. Business
transacted at any special meeting of stockholders shall be limited to the
purposes stated in the notice. Notice of any meeting shall not be required to be
given to any person who attends such meeting, except when such person attends
the meeting in person or by proxy for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened, or who, either before or after the meeting,
shall submit a signed written waiver of notice, in person or by proxy. Neither
the business to be transacted at, nor the purpose of, an annual or special
meeting of stockholders need be specified in any written waiver of notice.

                  SECTION 5. LIST OF STOCKHOLDERS ENTITLED TO VOTE. The officers
or agents who have charge of the stock ledger or transfer book of the
corporation shall prepare and make, at least ten days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the

and the number of shares of capital stock of the corporation registered in the
name of each stockholder. Such list shall be open to the examination of any
stockholder, for any purpose germane to the meeting, during ordinary business
hours, for a period of at least ten days prior to the meeting, either at a place
within the city where the meeting is to be held, which place shall be specified
in the notice of the meeting, or, if not so specified, at the place where the
meeting is to be held. The list shall also be produced and kept at the time and
place of the meeting during the whole time thereof, and may be inspected by any
stockholder who is present.

                  SECTION 6. SPECIAL MEETINGS. Special meetings of the
stockholders for any purpose or purposes, unless otherwise prescribed by
statute, by these By-Laws or by the certificate of incorporation, may be called
by the chairman of the board or by the president and shall be called by the
chairman of the board, president or secretary at the request in writing of a

                                       2
<PAGE>

majority of the board of directors, or at the request in writing of stockholders
owning a majority of the shares of capital stock of the corporation issued and
outstanding and entitled to vote. Such request shall state the purpose or
purposes of the proposed meeting. Business transacted at any special meeting of
stockholders shall be limited to the purposes stated in the notice.

                  SECTION 7. ORGANIZATION. At each meeting of stockholders, the
Chairman of the Board, if one shall have been elected, or, in such person's
absence or if one shall not have been elected, the President, shall act as
chairman of the meeting. The Secretary or, in such person's absence or inability
to act, the person whom the chairman of the meeting shall appoint secretary of
the meeting, shall act as secretary of the meeting and keep the minutes thereof.

                  SECTION 8. QUORUM; ADJOURNMENTS. The holders of a majority of
the shares of capital stock of the corporation issued and outstanding and
entitled to vote thereat, present in person, or represented by proxy, shall
constitute a quorum at all meetings of the stockholders for the transaction of
business except as otherwise provided by statute, by these By-Laws or by the
certificate of incorporation. Abstentions shall be counted as present in person
or represented by proxy for purposes of determining the existence of a quorum
for purposes of this Section 8. If, however, such quorum shall not be present or
represented at any meeting of the stockholders, the stockholders entitled to
vote thereat, present in person or represented by proxy, shall have the power to
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present or represented. At such adjourned
meeting at which a quorum shall be present or represented any business may be
transacted which might have been transacted at the meeting as originally
notified. If the adjournment is for more than thirty days, or if after the
adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each stockholder of record entitled to
vote at the meeting.

                  SECTION 9. VOTING. When a quorum is present at any meeting, a
majority of the votes cast shall decide any question (other than the election of
directors, which shall be determined by a plurality vote) brought before such
meeting, unless the question is one upon which by express provision of statute,
these By-Laws or of the certificate of incorporation, a different vote is
required, in which case such express provision shall govern and control the
decision of such question. Abstentions shall not be included in calculating the
number of votes cast on, in favor of, or in opposition to any question.

                  SECTION 10. VOTING POWER. Unless otherwise specifically
provided by statute, these By-Laws or the certificate of incorporation, each
stockholder shall at every meeting of the stockholders be entitled to one vote
for each Share held by such stockholder.

                  SECTION 11. PROXIES. Each stockholder entitled to vote at a
meeting of stockholders or to express consent or dissent to corporate action in
writing without a meeting may authorize another person or persons to act for him
by proxy, but no such proxy shall be voted or acted upon after three years from
its date, unless the proxy provides for a longer period.

                  SECTION 12. CONSENT OF STOCKHOLDERS IN LIEU OF MEETING. Unless
otherwise provided in the certificate of incorporation, any action required to
be taken at any annual or special meeting of stockholders of the corporation, or
any action which may be taken at any

                                       3
<PAGE>

annual or special meeting of such stockholders, may be taken without a meeting,
without prior notice and without a vote, if a consent or consents in writing,
setting forth the action so taken, shall be signed by the holders of outstanding
shares of capital stock of the corporation having not less than the minimum
number of votes that would be necessary to authorize or take such action at a
meeting at which all shares entitled to vote thereon were present and voted and
shall be delivered to the corporation by delivery to its registered office in
the State of Delaware, its principal place of business, or an officer or agent
of the corporation having custody of the book in which proceedings of meetings
of stockholders are recorded. Prompt notice of the taking of the corporate
action without a meeting by less than unanimous written consent shall be given
to those stockholders who have not consented in writing.

                  SECTION 13. INSPECTORS. The board of directors, in advance of
any stockholders' meeting, shall appoint one or more inspectors to act at the
meeting or any adjournment thereof and to make a written report thereof. In case
any person appointed fails to appear or act, the vacancy may be filled by
appointment made by the board of directors in advance of the meeting or at the
meeting by the persons presiding thereat. Each inspector, before entering upon
the discharge of his duties, shall take and sign an oath faithfully to execute
the duties of inspector at such meeting with strict impartiality and according
to the best of his ability.

                  The inspectors shall ascertain the number of shares of capital
stock of the corporation outstanding and the voting power of each, determine the
shares of capital stock of the corporation represented at the meeting and the
validity of proxies and ballots, count all votes and ballots, determine and
retain for a reasonable period a record of the disposition of any challenges
made to any determination by the inspectors, and certify their determination of
the number of shares of capital stock of the corporation represented at the
meeting and their count of all votes and ballots. The inspectors may appoint or
retain other persons or entities to assist the inspectors in the performance of
the duties of the inspectors.

                  In determining the validity and counting of proxies and
ballots, the inspectors shall be limited to an examination of the proxies, any
envelopes submitted with those proxies, any information provided in accordance
with Section 212(c)(2) of the Delaware General Corporation Law (the "DGCL"),
ballots and the regular books and records of the corporation, except that the
inspectors may consider other reliable information for the limited purpose of
reconciling proxies and ballots submitted by or on behalf of banks, brokers,
their nominees or similar persons which represent more votes than the holder of
a proxy is authorized by the record owner to cast or more votes than the
stockholder holds of record. If the inspectors consider other reliable
information for the limited purpose permitted herein, the inspectors at the time
they make their certification pursuant to the paragraph above shall specify the
precise information considered by them, including the person or persons from
whom they obtained the information, when the information was obtained, the means
by which the information was obtained and the basis for the inspectors' belief
that such information is accurate and reliable.

                  The date and time of the opening and the closing of the polls
for each matter upon which the stockholders will vote at a meeting shall be
announced at the meeting. No ballot, proxies or votes nor any revocations
thereof or changes thereto, shall be accepted by the

                                       4
<PAGE>

inspectors after the closing of the polls unless the Court of Chancery of the
State of Delaware, upon application by a stockholder, shall determine otherwise.

                  SECTION 1. NUMBER; ELECTION BY STOCKHOLDERS; FILLING
VACANCIES. The authorized number of directors may be determined from time to
time by a vote of a majority of the then authorized number of directors;
provided, however, that such number shall initially be eight, and provided
further, that such number shall not be less than three nor more than 11; and
provided further, that such number and such minimum and maximum may be increased
pursuant to resolution of the board adopted pursuant to the certificate of
incorporation. The directors shall be elected at annual meetings of stockholders
and may be elected at any special meeting of stockholders, except as otherwise
provided herein, and each director shall hold office until a successor is
elected and qualified or until that director's earlier resignation or removal.
Except as otherwise provided in the certificate of incorporation, newly created
directorships resulting from any increase in the number of directors and any
vacancies on the board of directors resulting from death, resignation,
disqualification, removal, or other cause shall be filled by the affirmative
vote of a majority of the remaining directors then in office, even if less than
a quorum of the board, or by a sole remaining director. Any director elected in
accordance with the preceding sentence shall hold office until the next annual
meeting of stockholders. No person shall serve as a director of this corporation
after the annual stockholders meeting next following his or her 70th birthday.

stockholder entitled to vote generally in the election of directors who complies
with the procedures set forth in this Section 2 of Article III. All nominations
by stockholders must be made pursuant to timely notice in proper written form to
the secretary of the corporation. To be timely, a stockholder's notice must be
delivered to or mailed and received at the principal executive offices of the
corporation not less than 30 days nor more than 60 days prior to the date of the
meeting; provided, however, that in the event that less than 40 days notice or
prior public disclosure of the date of the meeting is given to stockholders, for
such notice by the stockholder to be timely, it must be so received prior to the
date of the meeting and not later than the close of business on the tenth day
following the day on which such notice of the date of the meeting was mailed or
such public disclosure was made. To be in proper written form, such
stockholder's notice shall set forth in writing (a) as to each person whom the
stockholder proposes to nominate for election or reelection as a director, all
information relating to such person that is required to be disclosed in
solicitations of proxies for election of directors, or is otherwise required, in
each case pursuant to Regulation 14A under the Securities Exchange Act of 1934,
as amended, including, without limitation, such person's written consent to
being named in the proxy statement as a nominee and to serving as a director if
elected; and (b) as to the

                                       5

corporation's books, of such stockholder and (ii) the class and number of shares
of capital stock of the corporation which are beneficially owned by such
stockholder. At the request of the board of directors, any person nominated by
the board of directors, or a committee appointed by the board of directors, for
election as a director shall furnish to the secretary of the corporation the
information required to be set forth in a stockholder's notice of nomination
which pertains to the nominee. The chairman of the meeting shall, if the facts
warrant, determine and declare to the meeting that a nomination was not made in
accordance with the procedures prescribed by this Section 2 of Article III, and
the defective nomination shall thereupon be disregarded.

                  SECTION 3. POWERS OF THE BOARD OF DIRECTORS. The business of
the corporation shall be managed by its board of directors which may exercise
all such powers of the corporation and do all such lawful acts and things as are

directors. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the board of directors need be specified in the
notice or waiver of notice of such meeting except as provided in Article IV of
these By-Laws.

                  SECTION 7. QUORUM AND MANNER OF ACTING. At all meetings of the
board of directors, a majority of the entire board shall constitute a quorum for
the transaction of business and the act of a majority of the directors present
at any meeting at which there is a quorum shall be the act of the board of
directors, except as may be otherwise specifically provided by statute or by the
certificate of incorporation. If a quorum shall not be present at any meeting of
the board of directors, the directors present thereat may adjourn the meeting
from time to time, without notice other than announcement at the meeting, until
a quorum shall be present.

                  SECTION 8. ACTION BY CONSENT. Unless otherwise restricted by
the certificate of incorporation or these By-Laws, any action required or
permitted to be taken at any meeting of the board of directors, or of any
committee thereof, may be taken without a meeting, if all members of the board
or committee as the case may be, consent thereto in writing, and the writing or
writings are filed with the minutes of the proceedings of the board or
committee.

meeting of the committee. Any such committee, to the extent provided in the
resolution of the board of directors and to the extent permitted by Delaware
law, shall have and may exercise all of the powers and authority of the board of
directors in the management of the business and affairs of the corporation, and
may authorize the seal of the corporation to be affixed to all papers which may

directors.

                  SECTION 13. RESIGNATION. A resignation of a director shall be
effective upon receipt by the chairman of the board of a signed written notice

                  SECTION 14. REMOVAL. Any director may be removed from office
by the affirmative vote of the holders of at least a majority of the voting
power of all shares of capital stock of the corporation entitled to vote

other corporation, partnership, association, or other organization in which one
or more of its directors or officers are directors or officers, or have a
financial interest, shall be void or voidable solely for this reason, or solely
because the director or officer is present at or participates in the meeting of
the board of directors or a committee thereof which authorized the contract or
transaction, or solely because his or their votes are counted for such purpose,
if:

                  (a) The material facts as to his interest and as to the
contract or transaction are disclosed or are known to the board of directors or
committee, which in good faith authorizes the contract or transaction by a vote
sufficient for such purpose without counting the vote of the interested director
or directors; or

                  (b) The material facts as to his interest and as to the
contract or transaction are disclosed or are known to the stockholders entitled
to vote thereon, and the contract or transaction is specifically approved in
good faith by vote of the stockholders; or

                  (c) The contract or transaction is fair as to the corporation
as of the time it is authorized, approved or ratified by the board of directors
or the stockholders.

                  SECTION 1. RIGHT TO INDEMNIFICATION. Each person who was or is
a party or is threatened to be made a party to or is involved in or called as a
witness in any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, and any appeal
therefrom (hereinafter collectively a "proceeding"), by reason of the fact that
he, or a person of whom he is the legal representative, is, was or had agreed to
become a director, officer, or Delegate (as defined hereinafter) of the
corporation, shall be indemnified and held harmless by the corporation, to the
fullest extent permitted under the DGCL as the same now exists or may hereafter
be amended (but in the case of any such amendment, only to the extent that such
amendment permits the corporation to provide broader indemnification rights than
the DGCL permitted the corporation to provide prior to such amendment), against
all expenses (including, but not limited to, attorneys' fees and expenses of
litigation) reasonably incurred, and all liabilities and losses (including, but
not limited to, judgments, fines, excise taxes, ERISA penalties and amounts paid
in settlement) incurred by him in connection with such proceeding; provided that
except as explicitly provided herein, the corporation shall indemnify any such
person seeking indemnity in connection with a proceeding (or part thereof)
initiated by such person only if authorization for such proceeding (or part
thereof) initiated by such person was not denied by a majority of the board of
directors prior to the earlier of (i) 30 days after receipt of notice thereof
from such person or (ii) an Event, as defined hereinafter. For purposes of this
Article VII, a "Delegate" is any director or officer who is or was serving at
the request of the corporation or the board of directors as a director, officer,
trustee, fiduciary, partner, employee or agent of an entity or enterprise other
than the corporation (including, but not limited to, a partnership, joint
venture, trust, other corporation, or an employee benefit plan or trust); and an
"Event" shall be deemed to have occurred if (i) any "Person" (as that term is
used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as
amended) is or becomes (except in a transaction approved in advance by the board
of directors) the beneficial owner (as defined in Rule 13d-3 under such Act),
directly or indirectly, of securities of the corporation representing 25% or
more of the combined voting power of the corporation's then outstanding
securities, provided that the UNR Asbestos-Disease Claims Trust (as defined in
the Plan of Reorganization dated March 14, 1989 (the "Plan")) holding securities
of the corporation pursuant to the Plan shall not be deemed a Person for
purposes of this Article VII, or (ii) during any period of two consecutive
years, individuals who at the beginning of such period constitute the board of
directors of the corporation cease for any reason to constitute at least a
majority thereof unless the election of each director who was not a director at
the beginning of the period was approved by either (x) a vote of at least
two-thirds of the directors then still in office who were directors at the
beginning of the period or (y) the UNR Asbestos-Disease Claims Trust (as defined
in the Plan).

                  SECTION 2. EXPENSES. Expenses, including attorneys' fees,
incurred by a person indemnified pursuant to Section 1 of this Article VII in
defending or otherwise being involved in a proceeding shall be paid by the
corporation in advance of the final disposition of such proceeding upon receipt
of an undertaking (the "Undertaking") by or on behalf of such person to repay
such amount if it shall ultimately be determined that he is not entitled to be
indemnified by the corporation; provided that in connection with a proceeding
(or part thereof) initiated by such person except as provided in Section 3 of
this Article VII for proceedings to enforce a person's right to the advancing of
expenses for either a proceeding not initiated by such person or a proceeding
initiated by such person for which authorization was not denied, the corporation
shall pay said expenses in advance of final disposition only if authorization
for such proceeding (or part thereof) was not denied by a majority of the board
of directors of the corporation. A person to whom expenses are advanced pursuant
hereto shall not be obligated to repay pursuant to the Undertaking until the
final determination of any pending proceeding in a court of competent
jurisdiction, including appeals therefrom, concerning the right of such person
to be indemnified or the obligations of such person to repay pursuant to the
Undertaking.

                  SECTION 3. PROTECTION OF RIGHTS. If a claim under Section 1 of
this Article VII is not promptly paid in full by the corporation after a written
claim has been received by the corporation or if expenses pursuant to Section 2
of this Article VII have not been promptly advanced after a written request for
such advancement accompanied by the Undertaking has been received by the
corporation, the claimant may at any time thereafter bring suit against the
corporation to recover the unpaid amount of the claim or the advancement of
expenses. If successful, in whole or in part, in such suit such claimant shall
also be entitled to be paid the reasonable expense thereof. It shall be a
defense to any such action (other than an action brought to enforce a claim for
expenses incurred in defending any proceeding in advance of its final
disposition where the required Undertaking has been tendered to the corporation)
that the claimant has not met the standards of conduct which make it permissible
under the DGCL for the corporation to indemnify the claimant for the amount
claimed, but the burden of proving such defense shall be on the corporation. If
an Event has occurred, a claimant making a claim under Section 1 of this Article
VII or seeking to avoid repayment to the corporation pursuant to an Undertaking
shall have (i) the right, but not the obligation, to have a determination made
by independent legal counsel as to whether indemnification of the claimant is
proper because he has met the applicable standard of conduct required under the
DGCL, and (ii) the right to select as independent legal counsel for such purpose
any law firm designated for such purpose in a resolution adopted by a majority
of the board of directors prior to the Event and in full force and effect
immediately prior to the Event. If a determination has been made in accordance
with the preceding sentence, no determination inconsistent therewith by other
legal counsel, by the board of directors, or by stockholders shall be of any
force or effect. Neither the failure of the corporation (including its board of
directors, independent legal counsel, or its stockholders) to have made a
determination, if required, prior to the commencement of such action that
indemnification of the claimant is proper in the circumstances because he has
met the applicable standard of conduct required under the DGCL, nor an actual
determination by the corporation (including its board of directors, independent
legal counsel, or its stockholders) that the claimant had not met such
applicable standard of conduct, shall be a defense to the action or create a
presumption that claimant had not met the applicable standard of conduct.

                  SECTION 4.  MISCELLANEOUS.

                  (a) NON-EXCLUSIVITY OF RIGHTS. The rights conferred on any
person by this Article VII shall not be deemed exclusive of any other right
which such person may have or hereafter acquire under any statute, provision of
the certificate of incorporation, By-Law, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity at the request of the corporation while
holding such office, and shall, unless otherwise provided when authorized or
ratified, continue as to a person who has ceased to be a director, officer,
employee or agent and shall inure to the benefit of the heirs, executors and
administrators of such person. The board of directors shall have the authority,
by resolution, to provide for such indemnification of employees or agents of the
corporation or others and for such other indemnification of directors, officers
or Delegates as it shall deem appropriate.

                  (b) INSURANCE. The corporation shall have power to purchase
and maintain insurance, at its expense, to protect itself and any director,
officer, employee or agent of the corporation, or any person who is or was
serving at the request of the corporation in any other capacity with the
corporation, another corporation, a partnership, a joint venture, trust or other
enterprise against any expenses, liabilities or losses, asserted against him or
incurred by him in any such capacity, or arising out of his status as such,
whether or not the corporation would have the power to indemnify him against
such expenses, liabilities or losses under the DGCL.

                  (c) CONTRACTUAL NATURE. The provisions of this Article VII
shall be applicable to all proceedings commenced after its adoption, whether
such arise out of events, acts or omissions which occurred prior or subsequent
to such adoption, and shall continue as to a person who has ceased to be a
director, officer or Delegate and shall inure to the benefit of the heirs,
executors and administrators of such person. This Article VII shall be deemed to
be a contract between the corporation and each person who, at any time that this
Article VII is in effect, serves or agrees to serve in any capacity which
entitles him to indemnification hereunder and any repeal or other modification
of this Article VII or any repeal or modification of the DGCL or any other
applicable law shall not limit any rights of indemnification existing or arising
out of events, acts or omissions occurring prior to such repeal or modification
to enforce this Article VII with regard to acts, omissions or events arising
prior to such repeal or modification.

                  (d) SEVERABILITY. If this Article VII or any portion hereof
shall be invalidated or held to be unenforceable on any ground by any court of
competent jurisdiction, the decision of which shall not have been reversed on
appeal, such invalidity or unenforceability shall not affect the other
provisions hereof, and this Article VII shall be construed in all respects as if
such invalid or unenforceable provisions had been omitted therefrom.

                                  ARTICLE VIII

                          CERTIFICATES OF CAPITAL STOCK

                  SECTION 1. STOCK CERTIFICATES. Every holder of shares of
capital stock of the corporation shall be entitled to have a certificate, signed
by, or in the name of the corporation by,

                                       13
<PAGE>

the chairman of the board or the president or a vice president, and by the
treasurer or an assistant treasurer, or the secretary or an assistant secretary,
of the corporation, certifying the number of shares owned by him in the
corporation.

                  SECTION 2. FACSIMILE SIGNATURES. Any or all of the signatures
on the certificate may be facsimile. In case the chairman of the board, any
officer, transfer agent or registrar who has signed or whose facsimile signature
has been placed upon a certificate shall have ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the corporation with the same effect as if he were such officer, transfer
agent or registrar at the date of issue.

                  SECTION 3. LOST CERTIFICATES. The board of directors may
direct a new certificate or certificates of shares of capital stock of the
corporation to be issued in place of any certificate or certificates theretofore
issued by the corporation, alleged to have been lost, stolen or destroyed, upon
the making of an affidavit of that fact by the person claiming the certificate
of shares of capital stock of the corporation to be lost, stolen or destroyed.
When authorizing such issue of a new certificate or certificates, the board of
directors may, in its discretion and as condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or his legal representative, to advertise the same in such manner
as it shall require and/or to give the corporation a bond, in such sum as it may
direct as indemnity against any claim that may be made against the corporation
with respect to the certificate alleged to have been lost, stolen or destroyed.

                  SECTION 4. TRANSFER OF STOCK. Upon surrender to the
corporation or the transfer agent of the corporation of a certificate for shares
of capital stock of the corporation duly endorsed or accompanied by proper
evidence of succession, assignment or authority to transfer, it shall be the
duty of the corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transaction upon its books;
provided, however, that such duty shall be subject to federal and state
securities and other applicable laws, the certificate of incorporation, and any
legends and stop transfer instructions with respect to such old certificate.

                  SECTION 5. FIXING RECORDING DATE. In order that the
corporation may determine the stockholders entitled to notice of or to vote at
any meeting of stockholders or any adjournment thereof, or to express consent to
corporate action in writing without a meeting, or entitled to receive payment of
any dividend or other distribution or allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion or exchange of shares
of capital stock of the corporation or for the purpose of any other lawful
action, the board of directors may fix, in advance, a record date, which shall
not be more than sixty nor less than ten days before the date of such meeting,
nor more than sixty days prior to any other action. A determination of
stockholders of record entitled to notice of or to vote at a meeting of
stockholders shall apply to any adjournment of the meeting; provided, however,
that the board of directors may fix a new record date for the adjourned meeting.

                  SECTION 6. REGISTERED STOCKHOLDERS. The corporation shall be
entitled to recognize the exclusive right of a person registered on its books as
the owner of shares of capital

                                       14
<PAGE>

stock of the corporation to receive dividends, and to vote as such owner, and to
hold liable for calls and assessments a person registered on its books as the
owner of shares of capital stock of the corporation, and shall not be bound to
recognize any equitable or other claim to or interest in such share or shares of
capital stock of the corporation on the part of any other person, whether or not
it shall have express or other notice thereof, except as otherwise provided by
the laws of Delaware.

                                   ARTICLE IX

                  SECTION 2. MANAGEMENT. The president shall from time to time
appoint individuals to manage the operations of these divisions and these
individuals shall be designated by such titles as may be appropriate. These
titles shall include the name of the division and may include the word
president, vice-president or manager. Such individuals, however, irrespective of
such titles, shall not be, nor shall they be deemed to be, officers of the
corporation. Such division personnel shall be authorized to have general and
active management of the activities of their respective divisions, all subject
to the right of the president to (a) delegate any specific management power, (b)
fix their compensation, and (c) remove such personnel at any time without
further prior authorization of the board of directors.

stock of the corporation, subject to any additional requirements of the
certificate of incorporation, if any, may be declared by the board of directors
at any regular or special meeting, pursuant to law. Dividends may be paid in
cash, in property, or in shares of capital stock of the corporation, subject to
the provisions of the certificate of incorporation.

                  SECTION 2. RESERVES. Before payment of any dividend, there may
be set aside out of any funds of the corporation available for dividends such
sum or sums as the board of directors from time to time, in its absolute
discretion, shall think proper as a reserve or reserves to meeting
contingencies, or for equalizing dividends, or for repairing or maintaining any
property of the corporation, or for such other purpose as the board of directors
shall think conducive to the interest of the corporation, and the board of
directors may modify or abolish any such reserve in the manner in which it was
created.

<PAGE>

with the normal payroll practices of the Company, until April 30, 2001 or for

                           (e) NO MITIGATION. In no event shall the Executive be
obligated to seek other employment or take any other action by way of mitigation
of the amounts payable to the Executive under any of the provisions of this
Agreement, nor shall such amounts be reduced by any earnings or benefits that
the Executive may receive from any other source.

                           (f) INTERNAL REVENUE CODE SECTION 280G.
Notwithstanding anything contained in this Agreement to the contrary, to the
extent that any payment or distribution of any type to or for the benefit of the
Executive by the Company, any affiliate of the Company, any person who acquires
ownership or effective control of the Company or ownership of a substantial
portion of the Company's assets (within the meaning of Section 280G of the
Internal Revenue Code (the "Code"), and the regulations thereunder), or any
affiliate of such person, whether paid or payable or distributed or
distributable pursuant to the terms of this Agreement or otherwise (the "Total
Payments") is or will be subject to the excise tax imposed under Section 4999 of
the Code (the "Excise Tax"), then the Total Payments shall be reduced (but not
below zero) if and to the extent that a reduction in the Total Payments would
result in the Executive retaining a larger amount, on an after-tax basis (taking
into account federal, state and local income taxes and the Excise Tax), than if
the Employee received the entire amount of such Total Payments. Unless the
Executive shall have given prior written notice specifying a different order to
the Company to effectuate the foregoing, the Company shall reduce or eliminate
the Total Payments, by first reducing or eliminating the portion of the Total
Payments which are not payable in cash (other than Total Payments attributable
to stock options or other equity awards ("EQUITY AWARDS")) and then by reducing
or eliminating cash payments, in each case in reverse order beginning with
payments or benefits which are to be paid the latest in time, and then by
reducing Equity Awards in the manner which will maximize the after-tax benefit
to the Executive. Any notice given by the Executive pursuant to the preceding
sentence shall take precedence over the provisions of any other plan,
arrangement or agreement governing the Executive's rights and entitlements to
any benefits or compensation. The determination of whether the Total Payments
shall be reduced pursuant to the foregoing and the amount of such reduction
shall be made, at the

                                       4
<PAGE>

Company's expense, by an accounting firm selected by the Company which is one of
the five largest accounting firms in the United States (other than the Company's
regular independent auditor).

                           (g) For purposes of this SECTION 5, the Executive's
employment shall not be treated as terminated for so long as he is an employee
of the Company or any of its subsidiaries.

                  6. EXECUTIVE COVENANTS.

                           (a) UNAUTHORIZED DISCLOSURE. The Executive agrees and
understands that in the Executive's position with the Company, the Executive has
been and will be exposed to and has and will receive information relating to the
confidential affairs of the Company, its subsidiaries and affiliates, including
but not limited to technical information, intellectual property, business and
marketing plans, strategies, customer information, other information concerning
the products, promotions, development, financing, expansion plans, business
policies and practices of the Company, its subsidiaries and affiliates, and
other forms of information considered by the Company to be confidential and in
the nature of trade secrets ("Confidential Information"). The Executive agrees
that during the Employment Term and thereafter, the Executive will not disclose
such Confidential Information, either directly or indirectly, to any third
person or entity without the prior written consent of the Company. This
confidentiality covenant has no temporal, geographical or territorial
restriction. Upon termination of the Employment Term, the Executive will
promptly supply to the Company all property, keys, notes, memoranda, writings,
lists, files, reports, customer lists, correspondence, tapes, disks, cards,
surveys, maps, logs, machines, technical data or any other tangible product or
document which has been produced by, received by or otherwise submitted to the
Executive during or prior to the Employment Term. Any material breach of the
terms of this paragraph shall be considered Cause.

                           (b) NON-COMPETITION. By and in consideration of the
Company's entering into this Agreement and the payments to be made and benefits
to be provided by the Company hereunder, and further in consideration of the
Executive's exposure to the proprietary information of the Company, the
Executive agrees that the Executive will not, during the Employment Term, and
thereafter during the "Non-competition Term" (as defined below), directly or
indirectly, own, manage, operate, join, control, be employed by, or participate
in the ownership, management, operation or control of, or be connected in any
manner with, including but not limited to holding any position as a shareholder,
director, officer, consultant, independent contractor, employee, partner, or
investor in, any "Restricted Enterprise" (as defined below); PROVIDED, that in
no event shall the ownership of less than 1% of the outstanding equity
securities of any issuer whose securities are registered under the Securities
and Exchange Act of 1934, as amended, standing alone, be

                                       5
<PAGE>

prohibited by this SECTION 6(b). For purposes of this SECTION 6(b), the term
"RESTRICTED ENTERPRISE" shall mean any person, corporation, partnership or other
entity that competes, directly or indirectly, with any business or activity
conducted or proposed to be conducted by the Company or any of its subsidiaries
or affiliates as of the date of the Executive's termination of employment.
Following termination of the Employment Term, upon request of the Company, the
Executive shall notify the Company of the Executive's then current employment
status. For purposes of this Agreement, the "NON-COMPETITION TERM" shall mean
the period beginning on the Termination Date and ending on the second
anniversary of such date. Any material breach of the terms of this SECTION 6(b)
shall be considered Cause. Notwithstanding the foregoing, in the event the
Executive's employment with the Company is terminated following a Change in
Control by the Company without Cause or by the Executive for Good Reason, the
Executive shall not be subject to this SECTION 6(b), and this SECTION 6(b) shall
have no force or effect.

                           (c) NON-SOLICITATION. During the Non-competition
Term, the Executive shall not, and shall not cause any other person to,
interfere with or harm, or attempt to interfere with or harm, the relationship
of the Company, any of its subsidiaries or affiliates with, or endeavor to
entice away from the Company, any of its subsidiaries or affiliates, or hire,
any person who at any time during the Employment Term was an employee or
customer of the Company, or any of its subsidiaries or affiliates.
Notwithstanding the foregoing, in the event the Executive's employment with the
Company is terminated following a Change in Control by the Company without Cause
or by the Executive for Good Reason, the Executive shall not be subject to this
SECTION 6(c), and this SECTION 6(c) shall have no force or effect.

                           (d) REMEDIES. The Executive agrees that any breach of
the terms of this SECTION 6 would result in irreparable injury and damage to the
Company, its subsidiaries and/or affiliates for which the Company, its
subsidiaries and/or affiliates would have no adequate remedy at law; the
Executive therefore also agrees that in the event of said breach or any threat
of breach, the Company, its subsidiaries and/or affiliates, as applicable, shall
be entitled to an immediate injunction and restraining order to prevent such
breach and/or threatened breach and/or continued breach by the Executive and/or
any and all persons and/or entities acting for and/or with the Executive,
without having to prove damages, in addition to any other remedies to which the
Company, its subsidiaries and/or affiliates may be entitled at law or in equity.
The terms of this SECTION 6(d) shall not prevent the Company, its subsidiaries
and/or affiliates from pursuing any other available remedies for any breach or
threatened breach hereof, including but not limited to the recovery of damages
from the Executive. The Executive and the Company further agree that the
provisions of the covenants contained in this SECTION 6 are reasonable and
necessary to protect the businesses of the Company, its subsidiaries and
affiliates because of the Executive's access to Confidential Information and his
material participation in the operation of such businesses. The Executive hereby
acknowledges

                                       6
<PAGE>

that due to the global aspects of the Company's, its subsidiaries' and
affiliates' businesses and competitors it would not be appropriate to include
any geographic limitation on this SECTION 6. Should a court or arbitrator
determine, however, that any provision of the covenants contained in this
SECTION 6 are not reasonable or valid, either in period of time, geographical
area, or otherwise, the parties hereto agree that such covenants should be
interpreted and enforced to the maximum extent which such court or arbitrator
deems reasonable or valid.

                  The existence of any claim or cause of action by the Executive
against the Company, its subsidiaries and/or affiliates, whether predicated on
this Agreement or otherwise, shall not constitute a defense to the enforcement
by the Company of the covenants contained in this SECTION 6.

                  7. NON-WAIVER OF RIGHTS. The failure to enforce at any time
the provisions of this Agreement or to require at any time performance by any
other party of any of the provisions hereof shall in no way be construed to be a
waiver of such provisions or to affect either the validity of this Agreement or
any part hereof, or the right of any party to enforce each and every provision
in accordance with its terms.

                  8. NOTICES. Every notice relating to this Agreement shall be

HOWEVER, that no individual shall be considered a member of the Incumbent Board
if such individual initially assumed office as a result of either an actual or
threatened "Election Contest" (as described in Rule 14a-11 promulgated under the
Exchange Act) or other actual or threatened solicitation of proxies or consents
by or on behalf of a Person other than the Board (a "Proxy Contest"), including
by reason of any agreement intended to avoid or settle any Election Contest or
Proxy Contest; or

                           (c) The consummation of:

the Merger at least fifty percent (50%) of the outstanding common stock and the

percent (50%) or more of the combined voting power of the then outstanding
voting securities of the Surviving Corporation is not Beneficially Owned,
directly or indirectly by another corporation (a "Parent Corporation"), or (y)
the Parent Corporation, if fifty percent (50%) or more of the combined voting
power of the Surviving Corporation's then outstanding voting securities is

                                            (B) the individuals who were members
of the Incumbent Board immediately prior to the execution of the agreement
providing for the Merger, constitute at least a majority of the members of the
board of directors of, (x) the Surviving Corporation, if fifty percent (50%) or
more of the combined voting power of the then outstanding voting securities of
the Surviving Corporation is not Beneficially Owned, directly or indirectly by a
Parent Corporation, or (y) the Parent Corporation, if fifty percent (50%) or
more of the combined voting power of the Surviving Corporation's then
outstanding voting securities is Beneficially Owned, directly or indirectly, by

Merger had Beneficial Ownership of fifty percent (50%) or more of the then
outstanding Common Stock or Voting Securities, has Beneficial Ownership
immediately following the Merger, directly or indirectly, of fifty percent (50%)
or more of the combined voting power of the outstanding voting securities or
common stock of (x) the Surviving Corporation, if fifty percent (50%) or more of
the combined voting power of the then outstanding voting securities of the
Surviving Corporation is not Beneficially Owned, directly or indirectly by a
Parent Corporation, or (y) the Parent Corporation, if fifty percent (50%) or
more of the combined voting power of the Surviving Corporation's then
outstanding voting securities is Beneficially Owned, directly or indirectly, by

or substantially all of the assets of the Company to any Person (other than a
transfer to a Related Entity or under conditions that would constitute a
Non-Control Transaction with the disposition of assets being regarded as a
Merger for this purpose or the distribution to the Company's stockholders of the
stock of a Related Entity or any other assets).

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur
solely because any Person (the "Subject Person") acquired Beneficial Ownership
of more than the permitted amount of the then outstanding Common Stock or Voting
Securities as a result of the acquisition of Common Stock or Voting Securities
by the Company which, by reducing the number of Common Stock or Voting
Securities then outstanding, increases the proportional number of shares
Beneficially Owned by the Subject Persons, provided that if a Change in Control
would occur (but for the operation of this sentence) as a result of the
acquisition of Common Stock or Voting Securities by the Company, and after such
share acquisition by the Company, the Subject Person becomes the Beneficial
Owner of any additional Common Stock or Voting Securities which increases the
percentage of the then outstanding Common Stock or Voting Securities
Beneficially Owned by the Subject Person, then a Change in Control shall occur.

                  "DISABILITY" shall mean the inability of the Executive to
perform his duties, services and responsibilities hereunder by reason of a
physical or mental infirmity, as reasonably determined by the Board, for a total
of 180 calendar days in any twelve-month period during the Employment Term.

                  "GOOD REASON" shall mean after a Change in Control, the
occurrence of any of the following events: (i) a material diminution in the

Executive's Base Salary; or (iii) a relocation of the Company's corporate
headquarters to a location that is more than 50 miles from the location of the
corporate headquarters immediately before the Change in Control.

                  "PRO RATA BONUS AMOUNT" shall mean an amount equal to the
annual bonus paid to the Executive for the year prior to the year in which the
Executive's employment is terminated, multiplied by a fraction, the numerator of
which is the number of days elapsed from the beginning of the bonus period
through and including the Termination Date, and the denominator of which is 365.

The number of Stock Units so credited shall be determined by dividing the amount
of the retainer or fee otherwise paid in cash on such date by the Fair Market

receive one Share upon the Share Delivery Date. An election made under this

receive Stock Units must be made in writing and filed with the Secretary of the
Corporation prior to November 30 to be effective with respect to a retainer or

date for the payment of such dividend;

Stock Unit Account will be credited with a number of Stock


                                      -4-
<PAGE>

Units equal to the number of Stock Units in such account immediately prior to
such dividend multiplied by the number of Shares paid as a dividend per Share.

     5.3  VESTING. Participants shall be fully (100%) vested in their Stock
Unit Accounts at all times.

                   ARTICLE VI - PAYMENT OF STOCK UNIT ACCOUNT

     6.1  SHARE DELIVERY DATE. Upon the Share Delivery Date, one or more
certificates representing a number of Shares equal to the number of Stock Units
credited to the Participant's Stock Unit Account, including any Stock Units
credited as a result of dividend equivalents, (rounded to the nearest whole
number) shall be delivered to such Participant, or in the case of the
Participant's death or Disability, to the Participant's personal representative
or to the person to whom such Shares are transferred by will or by the
applicable laws of descent and distribution.

     6.2  TERMINATION FOR CAUSE. In the event a Participant's service as a
Nonemployee Director is terminated on account of (a) fraud or intentional
misrepresentation, or (b) embezzlement, misappropriation, or conversion of
assets or opportunities of the Corporation, all Stock Units awarded to such
Participant prior to the date of termination shall be immediately forfeited.


              ARTICLE VII - AMENDMENT, MODIFICATION AND TERMINATION

     7.1  AMENDMENT, MODIFICATION AND TERMINATION. Subject to the terms set
forth in this Section 7.1, the Board may terminate, amend, or modify the Plan at
any time and from time to time. The Plan shall terminate when all of the Shares
subject to it have been awarded according to the provisions of the Plan.

     Without the approval of the voting securityholders of the Corporation as
may be required by the Code, by the rules of Section 16 of the Exchange Act, by
any national securities exchange or system on which the Shares are then listed
or reported, or by a regulatory body having jurisdiction with respect hereto, no
such termination, amendment or modification may:

     (a)  Materially increase the total number of Shares which may be available
for grants of Awards under the Plan, except as provided in Section 4.2 herein;

     (b)  Materially modify the requirements with respect to eligibility to
participate in the Plan; or


                                      -5-
<PAGE>

     (c)  Materially increase the benefits accruing to Nonemployee Directors
under the Plan.

     7.2  AWARDS PREVIOUSLY GRANTED. Unless required by law, no termination,
amendment or modification of the Plan shall materially affect, in an adverse
manner, any Award previously granted under the Plan, without the consent of the
Participant to whom the Award was made.


                          ARTICLE VIII - MISCELLANEOUS


     8.1  NO RIGHTS OF A SHAREHOLDER. Participants shall have none of the rights
of shareholders of the Corporation with respect to any Stock Unit.

     8.2  NO RIGHT OF NOMINATION. Nothing in the Plan shall be deemed to create
any obligation on the part of the Board to nominate any Participant for
reelection by the Corporation's securityholders.

     8.3  NONASSIGNABILITY. The right to receive benefits under the Plan may not
be anticipated, alienated, sold, transferred, assigned, pledged, encumbered or
subjected to any garnishment, charge or legal process.

     8.4  UNSECURED GENERAL CREDITOR. Participants shall have no legal or
equitable rights, interest or claims in any property or assets of the
Corporation. For purposes of the payment of benefits under the Plan, any and all
of the Corporation's assets shall be, and remain, the general, unpledged
unrestricted assets of the Corporation. The Corporation's obligations under the
Plan shall be merely that of an unfunded and unsecured promise to make payments
in the future.

     8.5  REQUIREMENTS OF LAW. The granting of Awards under the Plan and the
issuance of stock certificates shall be subject to all applicable laws, rules,
and regulations and to such approvals by any governmental agencies or national
securities exchanges as may be required.

     8.6  EFFECTIVE DATE. The Amended and Restated Plan is effective as of
March 27, 2000.

                              ROHN INDUSTRIES, INC.
                             1999 STOCK OPTION PLAN
                         (AS AMENDED NOVEMBER 11, 1999)

         SECTION 1. PURPOSE. The purpose of the Rohn Industries, Inc. 1999 Stock
Option Plan (this "Plan") is to benefit Rohn Industries, Inc. (the "Company")
and its subsidiaries by offering certain present and future employees, including
officers, a favorable opportunity to become holders of stock in the Company over
a period of years, thereby giving them a stake in the growth and prosperity of
the Company and encouraging the continuance of their services with the Company
or its subsidiaries.

         SECTION 2. ADMINISTRATION.

         2.1 COMMITTEE. This Plan shall be administered by the Compensation
Committee (the "Committee") of the Board of Directors of the Company (the
"Board"). The Committee's interpretation and construction of any terms or
provisions of this Plan or any option issued hereunder, or of any rule or
regulation adopted in connection therewith, shall be conclusive and binding on
all interested parties, so long as such interpretation and construction with
respect to incentive stock options corresponds to the requirements of Section
422 of the Internal Revenue Code, as amended (the "Code") and the regulations
thereunder.

         2.2 GRANTS TO SECTION 16 PERSONS. For so long as the Company's Common
Stock is registered under Section 12 of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), the Committee may not grant options to an officer
of the Company subject to Section 16 of the Exchange Act unless the grant is (i)
approved in advance by the Committee in accordance with the provisions of Rule
16b-3(d)(1) under the Exchange Act (where the Committee is composed solely of
two or more non-employee directors who satisfy the requirements of Rule
16b-3(b)(3) under the Exchange Act), (ii) approved in advance, or subsequently
ratified by the stockholders in accordance with the provisions of Rule
16b-3(d)(2) under the Exchange Act or (iii) absent approval pursuant to clauses
(i) or (ii), no officer of the Company may sell shares received upon the
exercise of an option during the six-month period immediately following the
grant of such option.

         2.3 GRANTS TO SECTION 162(m) OFFICERS. The Board may not grant options
to an officer subject to Section 162(m) of the Code unless the grant is approved
by the Committee where the Committee is composed of at least two "outside
directors" (as defined in the regulations promulgated under Section 162(m) of
the Code).

         2.4 SECTION 16(b) COMPLIANCE AND BIFURCATION OF PLAN. It is the
intention of the Company that this Plan comply in all respects with Section
16(b) and Rule 16b-3 under the Exchange Act, to the extent applicable, and, if
any Plan provision is later found not to be in compliance with such Section or
Rule, the provision shall be deemed null and void, and the Plan shall be
construed in favor of its meeting the requirements of Section 16(b) and Rule
16b-3 under the Exchange Act. Notwithstanding anything in

<PAGE>

the Plan to the contrary, the Committee, in its absolute discretion, may
bifurcate the Plan so as to limit the use of any provision of the Plan to
participants who are executive officers or other persons subject to Section
16(b) of the Exchange Act without so restricting, limiting or conditioning the
Plan with respect to other participants.

         SECTION 3. STOCK SUBJECT TO THIS PLAN. The stock subject to this Plan
shall be the Company's common stock, par value $.01 per share (the "Common
Stock"), authorized but unissued or held in the Company's treasury or
subsequently acquired by the Company. Subject to adjustment as provided in
Section 7 hereof, the aggregate amount of Common Stock to be delivered upon the
exercise of all options granted under this Plan shall not exceed 2,500,000
shares as such Common Stock was constituted on the effective date of this Plan.
If any option granted under this Plan shall expire, or be surrendered, exchanged
for another option, canceled or terminated for any reason without having been
exercised in full, the unpurchased shares subject thereto shall thereupon again
be available for purposes of this Plan, including for replacement options which
may be granted in exchange for such surrendered, canceled or terminated options.

         SECTION 4. ELIGIBILITY. An incentive stock option may be granted only
to an individual who, at the time the option is granted, is an employee of the
Company or any subsidiary. A nonqualified stock option may be granted to any
employee of the Company or any subsidiary, whether an individual or an entity.
Any party to whom an option is granted under this Plan shall be referred to
hereinafter as an "Optionee."

         SECTION 5. TERMS AND CONDITIONS OF OPTIONS. Options granted under this
Plan shall contain such terms, conditions, limitations and restrictions as the
Committee shall deem advisable and which are not inconsistent with this Plan.
Notwithstanding the foregoing, options shall include or incorporate by reference
the following terms and conditions:

         5.1 NUMBER OF SHARES AND PRICE. The maximum number of shares that may
be purchased pursuant to the exercise of each option and the price per share at
which such option is exercisable (the "exercise price") shall be as established
by the Committee, provided that the Committee shall act in good faith to
establish an exercise price which shall be not less than the fair market value
per share of the Common Stock at the time the option is granted with respect to
incentive stock options and not less than 85% of the fair market value per share
of the Common Stock at the time the option is granted with respect to
nonqualified stock options and also provided that, with respect to incentive
stock options granted to greater than 10% stockholders, the exercise price shall
be as required by Section 6. In addition, in any five-year period, no individual
may be granted options under the Plan to purchase more than 1,000,000 shares of
Common Stock, subject to adjustment as set forth in Section 7.

         5.2 TERM AND MATURITY. Subject to the restrictions contained in Section
6 with respect to granting incentive stock options to greater than 10%
stockholders, the

                                       2
<PAGE>

term of each incentive stock option shall be as established by the Committee
and, if not so established, shall be 10 years from the date it is granted but in
no event shall the term of any incentive stock option exceed 10 years. The term
of each nonqualified stock option shall be as established by the Committee and,
if not so established, shall be 10 years from the date it is granted. To ensure
that the Company or its subsidiaries will achieve the purpose and receive the
benefits contemplated in this Plan, any option granted to any Optionee hereunder
shall, unless the condition of this sentence is waived by resolution adopted by
the Committee, be exercisable according to the following schedule:

<TABLE>
<CAPTION>

          PERIOD OF OPTIONEE'S
          CONTINUOUS EMPLOYMENT
       WITH THE COMPANY OR RELATED
        CORPORATION FROM THE DATE                PORTION OF TOTAL OPTION
          THE OPTION IS GRANTED                    WHICH IS EXERCISABLE
       ---------------------------               -----------------------
<S>                                            <C>
            after 1 year                                 33-1/3%
            after 2 years                                66-2/3%
            after 3 years                                   100%

</TABLE>

         5.3 EXERCISE. Subject to the vesting schedule described in Section 5.2
above, each option may be exercised in whole or in part; provided, however, that
no fewer than 100 shares (or the remaining shares then purchasable under the
option, if less than 100 shares) may be purchased upon any exercise of option
rights hereunder and that only whole shares will be issued pursuant to the
exercise of any option. Options shall be exercised by delivery to the Company of
notice of the number of shares with respect to which the option is exercised,
together with payment of the exercise price.

         5.4 PAYMENT OF EXERCISE PRICE. Payment of the option exercise price
shall be made in full at the time the notice of exercise of the option is
delivered to the Company and shall be in cash, bank certified or cashier's check
or personal check (unless at the time of exercise the Committee in a particular
case determines not to accept a personal check) for the Common Stock being
purchased.

         The Committee can determine at the time the option is granted for
incentive stock options, or at any time before exercise for nonqualified stock
options, that additional forms of payment will be permitted. To the extent
permitted by the Committee and applicable laws and regulations (including, but
not limited to, federal tax and securities laws and regulations and state
corporate law), an option may be exercised by:

                  (a) delivery of shares of Common Stock held by an Optionee
         having a fair market value equal to the exercise price, such fair
         market value to be determined in good faith by the Committee;

                                       3
<PAGE>

                  (b) delivery of a properly executed exercise notice, together
         with irrevocable instructions to a broker, all in accordance with the
         regulations of the Federal Reserve Board, to promptly deliver to the
         Company the amount of sale or loan proceeds to pay the exercise price
         and any federal, state or local withholding tax obligations that may
         arise in connection with the exercise; provided, that the Committee, in
         its sole discretion, may at any time determine that this subparagraph
         (b), to the extent the instructions to the broker call for an immediate
         sale of the shares, shall not be applicable to any Optionee whose
         employment with the Company has terminated prior to the time of
         exercise; or

                  (c) delivery of a properly executed exercise notice together
         with instructions to the Company to withhold from the shares that would
         otherwise be issued upon exercise that number of shares having a fair
         market value equal to the option exercise price.

         5.5 WITHHOLDING TAX REQUIREMENT. The Company or any subsidiary shall
have the right to retain and withhold from any payment of cash or Common Stock
under the Plan the amount of taxes required by any government to be withheld or
otherwise deducted and paid with respect to such payment. At its discretion, the
Company may require an Optionee receiving shares of Common Stock to reimburse
the Company for any such taxes required to be withheld by the Company and
withhold such shares in whole or in part until the Company is so reimbursed. In
lieu thereof, the Company shall have the right to withhold from any other cash
amounts due or to become due from the Company to the Optionee an amount equal to
such taxes or retain and withhold a number of shares having a market value not
less than the amount of such taxes required to be withheld by the Company to
reimburse the Company for any such taxes and cancel (in whole or in part) any
such shares so withheld. If required by Section 16(b) of the Exchange Act, the
election to pay withholding taxes by delivery of shares held by any person who
at the time of exercise is subject to Section 16(b) of the Exchange Act, shall
be made either six months prior to the date the option exercise becomes taxable
or at such other times as the Company may determine as necessary to comply with
Section 16(b) of the Exchange Act.

         5.6 ASSIGNABILITY AND TRANSFERABILITY OF OPTION. Options granted under
this Plan and the rights and privileges conferred hereby may not be transferred,
assigned, pledged or hypothecated in any manner (whether by operation of law or
otherwise) other than (i) by will or by the applicable laws of descent and
distribution, (ii) pursuant to a property settlement in connection with a
divorce proceeding, or (iii) as otherwise determined by the Committee by
resolution. Any attempt to transfer, assign, pledge, hypothecate or otherwise
dispose of any option under this Plan or of any right or privilege conferred
hereby, contrary to the Code or to the provisions of this Plan, or the sale or
levy or any attachment or similar process upon the rights and privileges
conferred hereby shall be null and void. The designation by an Optionee of a
beneficiary does not, in and of itself, constitute an impermissible transfer
under this Section.

                                       4
<PAGE>

         5.7 TERMINATION OF EMPLOYMENT. If the Optionee's employment with the
Company or any subsidiary ceases for any reason other than termination for
cause, death or total disability, and unless by its terms the option sooner
terminates or expires, then the Optionee may exercise, for an 18-month period
(and in the case of incentive stock options, for a three-month period) that
portion of the Optionee's option which is exercisable at the time of such
cessation, but the Optionee's option shall terminate at the end of the 18-month
period (three-month period for incentive stock options) following such cessation
as to all shares for which it has not theretofore been exercised, unless such
provision is waived by resolution adopted by the Committee within 90 days of
such cessation.

         If an Optionee is terminated for cause, any option granted hereunder
shall automatically terminate as of the first discovery by the Company of any
reason for termination for cause, and such Optionee shall thereupon have no
right to purchase any shares pursuant to such option. "Termination for cause"
shall mean dismissal for dishonesty, conviction or confession of a crime
punishable by law (except minor violations), fraud, misconduct or unauthorized
disclosure of confidential information. If an Optionee's employment with the
Company or any subsidiary is suspended pending an investigation of whether or
not the Optionee shall be terminated for cause, all Optionee's rights under any
option granted hereunder likewise shall be suspended during the period of
investigation.

         If an Optionee's employment with the Company or any subsidiary ceases
because of a total disability, the Optionee's option shall not terminate until
the end of the 18-month period and, in the case of an incentive stock option,
shall not cease to be treated as an incentive stock option until the end of the
12-month period, following such cessation (unless by its terms it sooner
terminates and expires). As used in this Plan, the term "total disability"
refers to a mental or physical impairment of the Optionee which is expected to
result in death or which has lasted or is expected to last for a continuous
period of 12 months or more and which causes the Optionee to be unable, in the
opinion of the Company and two independent physicians, to perform his or her
duties for the Company and to be engaged in any substantial gainful activity.
Total disability shall be deemed to have occurred on the first day after the
Company and the two independent physicians have furnished their opinion of total
disability to the Committee.

         For purposes of this Section 5.7, a transfer of employment between or
among the Company and/or any subsidiary shall not be deemed to constitute a
cessation of employment with the Company or any subsidiary. For purposes of this
Section 5.7, with respect to incentive stock options, employment shall be deemed
to continue while the Optionee is on military leave, sick leave or other bona
fide leave of absence (as determined by the Committee). The foregoing
notwithstanding, employment shall not be deemed to continue beyond the first 90
days of such leave, unless the Optionee's reemployment rights are guaranteed by
statute or by contract.

                                       5
<PAGE>

         5.8 DEATH OF OPTIONEE. If an Optionee dies while he or she is employed
by the Company or any subsidiary or within the 12-month period following
cessation of such employment, any option held by such Optionee to the extent
that the Optionee would have been entitled to exercise such option, may be
exercised within 12 months after his or her death by the personal representative
of his or her estate or by the person or persons to whom the Optionee's rights
under the option shall pass by will or by the applicable laws of descent and
distribution.

         5.9 STATUS OF SHAREHOLDER. Neither the Optionee nor any party to which
the Optionee's rights and privileges under the option may pass shall be, or have
any of the rights or privileges of, a shareholder of the Company with respect to
any of the shares issuable upon the exercise of any option granted under this
Plan unless and until such option has been exercised.

         5.10 CONTINUATION OF EMPLOYMENT. Nothing in this Plan or in any option
granted pursuant to this Plan shall confer upon any Optionee any right to
continue in the employ of the Company or of a subsidiary, or to interfere in any
way with the right of the Company or of any such subsidiary to terminate his or
her employment with the Company at any time.

         5.11 MODIFICATION AND AMENDMENT OF OPTION. Subject to the requirements
of Code Section 422 with respect to incentive stock options and to the terms and
conditions and within the limitations of this Plan, the Committee may modify or
amend outstanding options granted under this Plan. The modification or amendment
of an outstanding option shall not, without the consent of the Optionee, impair
or diminish any of his or her rights or any of the obligations of the Company
under such option. Except as otherwise provided in this Plan, no outstanding
option shall be terminated without the consent of the Optionee. Unless the
Optionee agrees otherwise, any changes or adjustments made to outstanding
incentive stock options granted under this Plan shall be made in such a manner
so as not to constitute a "modification" as defined in Code Section 424(h) and
so as not to cause any incentive stock option issued hereunder to fail to
continue to qualify as an incentive stock option as defined in Code Section
422(b).

         5.12 LIMITATION ON VALUE FOR INCENTIVE STOCK OPTIONS. As to all
incentive stock options granted under the terms of this Plan, to the extent that
the aggregate fair market value (determined at the time the incentive stock
option is granted) of the stock with respect to which incentive stock options
are exercisable for the first time by the Optionee during any calendar year
(under this Plan and all other incentive stock option plans of the Company, a
subsidiary or a predecessor corporation) exceeds $100,000, such options shall be
treated as nonqualified stock options. The previous sentence shall not apply if
the Code is amended or if the Internal Revenue Service publicly rules, issues a
private ruling to the Company, any Optionee, or any legatee, personal
representative or distributee of an Optionee or issues regulations, changing or

                                       6
<PAGE>

eliminating such annual limit, in which case the limitation shall be that
provided by the Code or the Internal Revenue Service, as the case may be.

         5.13 VALUATION OF COMMON STOCK RECEIVED UPON EXERCISE

                  5.13.1 EXERCISE OF OPTIONS UNDER SECTIONS 5.4(a) AND (c). The
         value of Common Stock received by the Optionee from an exercise under
         Sections 5.4(a) and 5.4(c) hereof shall be the fair market value as
         determined by the Committee, provided that, if the Common Stock is
         traded in a public market, such valuation shall be the average of the
         high and low trading prices or bid and asked prices, as applicable, of
         the Common Stock for the date of receipt by the Company of the
         Optionee's delivery of shares under Section 5.4(a) hereof or delivery
         of the exercise notice under Section 5.4(c) hereof.

                  5.13.2 EXERCISE OF OPTION UNDER SECTION 5.4(b). The value of
         Common Stock received by the Optionee from an exercise under Section
         5.4(b) hereof shall equal (a) in the case of the sale of the Common
         Stock received as a result of the exercise by a broker on the date of
         receipt by the Company of the Optionee's exercise notice, the sales
         price received for such shares; and (b) in all other cases, the average
         of the high and low trading prices or bid and asked prices, as
         applicable, of the Common Stock for the date of receipt by the Company
         of the Optionee's exercise notice.

         SECTION 6. GREATER THAN 10% STOCKHOLDERS.

         6.1 EXERCISE PRICE AND TERM OF INCENTIVE STOCK OPTIONS. If incentive
stock options are granted under this Plan to employees who own more than 10% of
the total combined voting power of all classes of stock of the Company or any
subsidiary, the term of such incentive stock options shall not exceed five years
and the exercise price shall be not less than 110% of the fair market value of
the Common Stock at the time the incentive stock option is granted. This
provision shall control notwithstanding any contrary terms contained in any
other document. The term and exercise price limitations of this provision shall
be amended to conform to any change required by a change in the Code or by a
ruling or pronouncement of the Internal Revenue Service.

         6.2 ATTRIBUTION RULE. For purposes of Section 6.1, in determining stock
ownership, an employee shall be deemed to own the stock owned, directly or
indirectly, by or for his or her brothers, sisters, spouse, ancestors and lineal
descendants. Stock owned, directly or indirectly, by or for a corporation,
partnership, estate or trust shall be deemed to be owned proportionately by or
for its stockholders, partners or beneficiaries. If an employee or a person
related to the employee owns an unexercised option or warrant to purchase stock
of the Company, the stock subject to that portion of the option or warrant which
is unexercised shall not be counted in determining stock ownership. For purposes
of this Section 6, stock owned by an employee shall include

                                       7
<PAGE>

all stock owned by him which is actually issued and outstanding immediately
before the grant of the incentive stock option to the employee.

         SECTION 7. ADJUSTMENT.

         7.1 UPON CHANGES IN CAPITALIZATION. The aggregate number and class of
shares for which options may be granted under this Plan, the number and class of
shares covered by each outstanding option, and the exercise price per share
thereof (but not the total price), and each such option, shall all be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a split-up or consolidation of shares or
any like capital adjustment, or the payment of any stock dividend.

         7.2 EFFECT OF CHANGE IN CONTROL.

                  7.2.1 Except as otherwise determined by the Committee at the
         time an option is granted, options outstanding on the date of a Change
         of Control and held by an Optionee who is an employee of the Company or
         any subsidiary on such date shall be immediately exercisable in full on
         or after such date during its term, without regard to any time of
         exercise established under Section 5 hereof. "Change in Control" shall
         mean the occurrence, at any time during the specified term of an option
         granted under the Plan, of any of the following events:

                           (i) The acquisition, by a person or group of persons
                  acting in concert, of a beneficial ownership interest in the
                  Company, resulting in the total beneficial ownership of such
                  persons or group of persons equaling or exceeding 50% of the
                  outstanding Common Stock; provided, however, that no such
                  person or group of persons shall be deemed to beneficially own
                  (i) any Common Stock acquired directly from the Company or
                  (ii) any Common Stock held by the Company or any subsidiary or
                  any employee benefit plan (or any related trust) of the
                  Company or its subsidiaries. The Change in Control shall be
                  deemed to occur on the date the beneficial ownership of the
                  acquiring person or group of persons first equals or exceeds
                  50% of the outstanding Common Stock.

                           (ii) A change, within any period of 24 months or
                  less, in the composition of the Board such that at the end of
                  such period a majority of the directors who are then serving
                  were not serving at the beginning of such period, unless at
                  the end of such period the majority of the directors in office
                  were nominated upon the recommendation of a majority of the
                  Board at the beginning of such period. The Change in Control
                  shall be deemed to occur on the date the last director
                  necessary to result in a Change in Control takes office or
                  resigns from office, as applicable.

                           (iii) Approval by shareholders of the Company of a
                  merger, consolidation or other reorganization having
                  substantially the same effect,

                                       8
<PAGE>

                  or the sale of all or substantially all the consolidated
                  assets of the Company in each case, with respect to which the
                  persons or group of persons who were the respective beneficial
                  owners of the Common Stock immediately prior to such event do
                  not, following such event, beneficially own, directly or
                  indirectly, more than 50% of the then outstanding voting
                  securities of the Company resulting from such event or the
                  Company purchasing or receiving assets pursuant to such event.

                  If more than one of the foregoing events shall occur, each
         such event shall constitute a separate Change in Control.

                  7.2.2 Except as otherwise determined by the Committee at the
         time an option is granted, notwithstanding any other provisions in the
         Plan, prior to the passage of one year from and after any Change in
         Control, each Optionee shall have the right to require the Company (or,
         if the Company is not the survivor of a merger, consolidation or
         reorganization with an acquiror, the acquiror) to purchase from him or
         her any or all unexercised options granted under this Plan at a
         purchase price equal to (i) the excess of the fair market value per
         share over the exercise price multiplied by (ii) the number of option
         shares specified by the Optionee for purchase in a written notice to
         the Company (or, if the Company is not the survivor of a merger,
         consolidation or reorganization with an acquiror, the acquiror),
         attention of the Secretary.

                  7.2.3 For purposes of Section 7.2.2 above, "fair market value
         per share" shall mean, (i) except in the case of a merger,
         consolidation or reorganization with an acquiror in which the Company
         is not the survivor (a "Termination Merger"), the higher of (A) the
         average of the highest sales price per share of the Company's Common
         Stock on the NASDAQ Stock Market (as reported in THE WALL STREET
         JOURNAL, Midwest Edition) (or, if the Company's Common Stock is not
         then traded on the NASDAQ Stock market, on the principal market where
         such Common Stock is actively traded) on each of the five trading days
         immediately preceding the date the Optionee so notifies the Company or
         (B) the average of the highest sales price per share of the Company's
         Common Stock on the NASDAQ Stock Market (as reported in THE WALL STREET
         JOURNAL, Midwest Edition) (or, if the Company's Common Stock is not
         then traded on the NASDAQ Stock Market, reported on the principal
         market where such Common Stock is actively traded) on each of the five
         trading days immediately preceding the date of the Change in Control,
         and (ii) in the case of a Termination Merger, the higher of (C) the
         fair market value of the consideration receivable per share by holders
         of Common Stock in such Termination Merger, which fair market value
         as to any securities included in such consideration shall be the
         average of the highest sales price per unit of such security on the
         NASDAQ Stock Market (as reported in THE WALL STREET JOURNAL, Midwest
         Edition) (or, if such security is not then traded on the NASDAQ Stock
         Market, reported on the principal market where such security is
         actively traded) on each of the five trading days immediately


                                       9
<PAGE>



         preceding the date of the Termination Merger and as to any such
         security not actively traded in any market and as to all other property
         included in such consideration, shall be the amount determined by the
         Committee in its discretion or (D) the amount determined pursuant to
         Clause (i)(B) of this Section 7.2.3. The amount payable to each
         Optionee by the Company or acquiror, as the case may be, shall be in
         cash or by certified check and shall be reduced by any taxes required
         to be withheld.

         7.3 FRACTIONAL SHARES. In the event of any adjustment in the number of
shares covered by an option, any fractional shares resulting from such
adjustment shall be disregarded and each such option shall cover only the number
of full shares resulting from such adjustment.

         7.4 DETERMINATION OF COMMITTEE TO BE FINAL. All Section 7 adjustments
shall be made by the Committee, and its determination as to what adjustments
shall be made, and the extent thereof, shall be final, binding and conclusive.
Unless an Optionee agrees otherwise, any change or adjustment to an incentive
stock option shall be made in such a manner so as not to constitute a
"modification" as defined in Code Section 424(h) and so as not to cause his or
her incentive stock option issued hereunder to fail to continue to qualify as an
incentive stock option as defined in Code Section 422(b).

         SECTION 8. SECURITIES REGULATION. Shares shall not be issued with
respect to an option granted under this Plan unless the exercise of such option
and the issuance and delivery of such shares pursuant thereto shall comply with
all relevant provisions of law, including, without limitation, any applicable
state securities laws, the Securities Act of 1933, as amended, the Exchange Act,
the rules and regulations promulgated thereunder, and the requirements of any
stock exchange or inter-dealer quotation system upon which the shares may then
be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance, including the availability of an
exemption from registration for the issuance and sale of any shares hereunder.
Inability of the Company to obtain from any regulatory body having jurisdiction
the authority deemed by the Company's counsel to be necessary for the lawful
issuance and sale of any shares hereunder or the unavailability of an exemption
from registration for the issuance and sale of any shares hereunder shall
relieve the Company of any liability in respect of the nonissuance or sale of
such shares as to which such requisite authority shall not have been obtained.

         As a condition to the exercise of an option, the Company may require
the Optionee to represent and warrant at the time of any such exercise that the
shares are being purchased only for investment and without any present intention
to sell or distribute such shares if, in the opinion of counsel for the Company,
such representation is required by any relevant provision of the aforementioned
laws. At the option of the Company, a stop-transfer order against any shares of
stock may be placed on the official stock books and records of the Company, and
a legend indicating

                                       10
<PAGE>

that the stock may not be pledged, sold or otherwise transferred unless an
opinion of counsel is provided (concurred in by counsel for the Company) stating
that such transfer is not in violation of any applicable law or regulation, may
be stamped on stock certificates in order to assure exemption from registration.
The Company may also require such other action or agreement by the Optionees as
it may from time to time deem to be necessary or advisable. THE COMPANY SHALL
NOT BE OBLIGATED, BY REASON OF THIS PROVISION OR OTHERWISE, TO UNDERTAKE
REGISTRATION OF THE OPTIONS OR STOCK HEREUNDER.

         Should any of the Company's capital stock of the same class as the
stock subject to options granted hereunder be listed on a national securities
exchange or inter-dealer quotation system, shares shall not be issued with
respect to an option granted this Plan unless, prior to issuance, such exchange
or inter-dealer quotation system shall have authorized the listing of the shares
thereon.

         SECTION 9. AMENDMENT AND TERMINATION.

         9.1 BOARD ACTION. The Board may at any time suspend, amend or terminate
this Plan, provided that except as set forth in Section 7, the approval of the
holders of a majority of the Company's outstanding shares of voting capital
stock present and entitled to vote at any meeting is necessary for the adoption
by the Board of any amendment which will:

                  (a) increase the number of shares which are to be reserved for
         the issuance of options under this Plan;

                  (b) permit the granting of stock options to a class of persons
         other than those currently permitted to receive stock options under
         this Plan; or

                  (c) require shareholder approval under applicable law,
         including Section 16(b) of the Exchange Act.

         9.2 AUTOMATIC TERMINATION. Unless sooner terminated by the Board, this
Plan shall terminate ten years from the earlier of (a) the date on which this
Plan is adopted by the Board or (b) the date on which this Plan is approved by
the stockholders of the Company. No option may be granted after such termination
or during any suspension of this Plan. The amendment or termination of this Plan
shall not, without the consent of the option holder, alter or impair any rights
or obligations under any option theretofore granted under this Plan.

         SECTION 10. EFFECTIVENESS OF THIS PLAN. This Plan shall become
effective upon adoption by the Board so long as it is approved by the holders of
a majority of the Company's outstanding shares of voting capital stock present
and entitled to vote at any meeting at any time within 12 months before or after
the adoption of this Plan. Options may be granted hereunder prior to such
stockholder approval, but subject thereto.

                            INDEMNIFICATION AGREEMENT

         THIS AGREEMENT, made and entered into this ___ day of ____________,
19__ ("Agreement"), by and between ROHN Industries, Inc. a Delaware corporation
("Corporation", which term shall include one or more of its subsidiaries where
appropriate), and ____________________ ("Indemnitee"):

         WHEREAS, highly competent persons are becoming more reluctant to serve
corporations as directors or officers or in other capacities unless they are
provided with adequate protection through insurance or adequate indemnification
against inordinate risks of claims and actions against them arising out of their
service to, and activities on behalf of, such corporations; and

         WHEREAS, the current impracticability of obtaining adequate insurance
and the uncertainties relating to indemnification have increased the difficulty
of attracting and retaining such persons;

         WHEREAS, the Board of Directors of the Corporation (the "Board") has
determined that the difficulty in attracting and retaining such persons is
detrimental to the best interests of the Corporation's stockholders and that the
Corporation should act to assure such persons that there will be increased
certainty of such protection in the future;

         WHEREAS, it is reasonable, prudent and necessary for the Corporation
contractually to obligate itself to indemnify such persons to the fullest extent
permitted by applicable law so that they will serve or continue to serve the
Corporation free from undue concern that they will not be so indemnified; and

         WHEREAS, Indemnitee is willing to serve, continue to serve and/or to
undertake additional service for or on behalf of the Corporation on the
condition that he be so indemnified; and

         NOW, THEREFORE, in consideration of the premises and the covenants
contained herein, the Corporation and Indemnitee do hereby covenant and agree as
follows:

         1. SERVICES BY INDEMNITEE. Indemnitee agrees to serve or continue to
serve as a director and/or officer of the Corporation. This Agreement shall not
impose any obligation on the Indemnitee or the Corporation to continue the
Indemnitee's position with the Corporation beyond any period otherwise
applicable.

                                       2
<PAGE>

         2. GENERAL. The Corporation shall indemnify Indemnitee for, and hold
Indemnitee harmless from and against, any Losses or Expenses (as hereinafter
defined) at any time incurred by or assessed against Indemnitee arising out of
or in connection with the service of Indemnitee as a director or officer of the
Corporation to the fullest extent permitted by the laws of the State of Delaware
in effect on the date hereof or as such laws may from time to time hereafter be
amended to increase the scope of such permitted indemnification. Without
diminishing the scope of such permitted indemnification provided by this
Section, the rights of indemnification of Indemnitee provided hereunder shall
include but shall not be limited to those rights set forth hereinafter.

         3. PROCEEDINGS OTHER THAN PROCEEDINGS BY OR IN THE RIGHT OF THE
CORPORATION. Indemnitee shall be entitled to the rights of indemnification
provided in this Section 3 if, by reason of (a) his Corporate Status (as
hereinafter defined) or (b) anything done or not done by Indemnitee in any such
capacity, he, was or is, or is threatened to be made, a party to any Proceeding
(as hereinafter defined) or is involved (including, without limitation as a
witness) in an Proceeding, other than a Proceeding by or in the right of the
Corporation. Pursuant to this Section 3, Indemnitee shall be indemnified against
all Losses and Expenses actually and reasonably incurred by him or on his behalf
in connection with such Proceeding or any claim, issue or matter therein, if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal Proceeding, had no reasonable cause to believe his conduct was
unlawful.

         4. PROCEEDINGS BY OR IN THE RIGHT OF THE CORPORATION. Indemnitee shall
be Entitled to the rights of indemnification provided in this Section 4 if, by
reason of (a) his Corporate Status or (b) anything done or not done by
Indemnitee in any such capacity he was or is, or is threatened to be made, a
party to any, Proceeding brought by or in the right of the Corporation to
procure a judgment in its favor. Pursuant to this Section 4, Indemnitee shall be
indemnified against all Losses and Expenses actually and reasonably incurred by
him or on his behalf in connection with the defense or settlement of such
Proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Corporation. Notwithstanding
the foregoing, no indemnification against such Losses or Expenses shall be made
in respect of any claim, issue or matter as to which Indemnitee shall have been
adjudged to be liable to the Corporation if such indemnification is not
permitted by Delaware or other applicable law, provided, however, that
indemnification against all Losses and Expenses shall nevertheless be made by
the Corporation in such event to the extent that the Court of Chancery of the
State of Delaware, or the court in which such proceeding shall have been brought
or is pending, shall determine.

                                       3
<PAGE>

         5. INDEMNIFICATION FOR LOSSES AND EXPENSES OF A PARTY WHO IS WHOLLY OR
PARTLY SUCCESSFUL. Notwithstanding any other provision of this Agreement, to the
extent that Indemnitee is, by reason of (a) his Corporate Status or (b) anything
done or not done by Indemnitee in any such capacity, a party to and is wholly
successful, on the merits or otherwise, in any Proceeding, he shall be
indemnified against all Losses and Expenses actually and reasonably incurred by
him or on his behalf in connection therewith. If Indemnitee is not wholly
successful in such Proceeding but is successful, on the merits or otherwise, as
to one or more but less than all claims, issues or matters in such proceeding,
the Corporation shall indemnify Indemnitee to the maximum extent permitted by
law against all Losses and Expenses actually and reasonably incurred by him or
on his behalf in connection with each successfully resolved claim, issue or
matter. In any review or Proceeding to determine the extent of indemnification,
the Corporation shall bear the burden of proving any lack of success and which
amounts sought in indemnity are allocable to claims, issue or matters which were
not successfully resolved. For purposes of this Section 5 and without
limitation, the termination of any claim, issue or matter in such a Proceeding
by dismissal or withdrawal with or without prejudice, shall be deemed to be a
successful result as to such claims, issue or matter.

         6. PAYMENT FOR EXPENSES OF A WITNESS. Notwithstanding any other
provision of this Agreement, to the extent that Indemnitee is, by reason of his
Corporate Status, a witness in any Proceeding, the Corporation agrees to pay to
Indemnitee all Expenses actually and reasonably incurred by Indemnitee or on
Indemnitee's behalf in connection therewith.

         7. ADVANCEMENT OF EXPENSES. The Corporation shall advance all
reasonable Expenses incurred by or on behalf of Indemnitee (or reasonably
expected by Indemnitee to be incurred by Indemnitee within three months) in
connection with any Proceeding within twenty (20) days after the receipt by the
Corporation of a statement or statements from Indemnitee requesting such advance
or advances from time to time, whether prior to or after final disposition of
such Proceeding, whether or not a determination to indemnify has been made under
Section 8. Indemnitee's entitlement to such advancement of Expenses shall
include those incurred in connection with any Proceeding by Indemnitee seeking
an adjudication or award in arbitration pursuant to this Agreement. The
financial ability of Indemnitee to repay an advance shall not be a prerequisite
to the making of such advance. Such statement or statements shall reasonably
evidence the Expenses (which shall not include in any case the right of
indemnitee to receive payments pursuant to Section 6 and Section 7 hereof, which
shall not be subject to this Section 8), incurred (or reasonably expected to be
incurred) by Indemnitee in connection therewith and shall include or be preceded
or accompanied by an undertaking by or on behalf of Indemnitee to repay any
Expenses advanced if it shall ultimately be determined pursuant to the terms of
this agreement that Indemnitee is not entitled to be indemnified against such
Expenses. Unpaid expenses shall bear

                                       4
<PAGE>

interest accruing at the prime rate of interest from the twenty-first (21) day
after receipt by the Corporation of such statement until said expenses are paid.

         8. PROCEDURE FOR DETERMINATION OF ENTITLEMENT TO INDEMNIFICATION.

         (a) To obtain indemnification under this Agreement, Indemnitee shall
         submit to the Corporation a written request, including therein or
         therewith such documentation and information as is reasonably available
         to Indemnitee and is reasonably necessary to determine whether and to
         what extent Indemnitee is entitled to indemnification. Determination of
         Indemnitee's entitlement to indemnification shall be made promptly, but
         in no event later than 60 days after receipt by the Corporation of
         Indemnitee's written request for indemnification. The Secretary of the
         Corporation shall, promptly upon receipt of such a request for
         indemnification, advise the Board and counsel for the Corporation in
         writing the Indemnitee has requested indemnification.

         (b) Upon written request by Indemnitee for indemnification pursuant to
         Section 8(a) hereof, a determination, if required by applicable law,
         with respect to Indemnitee's entitlement thereto shall be made in the
         specific case: (i) if a Change in Control (as hereinafter defined)
         shall have occurred, by Independent Counsel (as hereinafter defined) in
         a written opinion to the Board, a copy of which shall be delivered to
         Indemnitee (unless Indemnitee shall request that such determination be
         made by the Board or the stockholders, in which case the determination
         shall be made in the manner provided below in clause (ii) or (iii);
         (ii) if a Change of Control shall not have occurred, (A) by the Board
         by a majority vote even though less than a quorum consisting of
         Disinterested Directors (as hereinafter defined), (B) by a committee of
         such directors designated by majority vote of such directors, even
         though less than a quorum (B) if there are no such directors or if
         directors so directs, by Independent Counsel in a written opinion to
         the Board, a copy of which shall be delivered to Indemnitee, or (C) by
         the stockholders of the Corporation; or (iii) as provided in Section
         9(b) of this Agreement; and, if it is so determined that Indemnitee is
         entitled to the indemnification, payment to Indemnitee shall be made
         within ten (10) days after such determination. Indemnitee shall
         cooperate with the person, persons or entity making such determination
         with respect to Indemnitee's entitlement to indemnification, including
         providing to such person, persons or entity upon reasonable advance
         request any documentation or information that is not privileged or
         otherwise protected from disclosure and which is reasonably available
         to Indemnitee and reasonably necessary to such determination. Any costs
         or expenses (including attorneys' fees and disbursements) incurred by
         Indemnitee in so cooperating shall be borne by the Corporation
         (irrespective of the determination as to Indemnitee's entitlement to
         indemnification) and the

                                       5
<PAGE>

         Corporation hereby indemnifies and agrees to hold Indemnitee harmless
         therefrom.

         (c) If the determination of entitlement to indemnification is to be
         made by Independent Counsel pursuant to Section 8(b) of this Agreement,
         the Independent Counsel shall be selected as provided in this Section
         8(c). If a Change of Control shall not have occurred, the Independent
         Counsel shall be selected by the Board, and the Corporation shall give
         written notice to Indemnitee advising him of the identity of the
         Independent Counsel so selected. If a Change of Control shall have
         occurred, the Independent Counsel shall be selected by Indemnitee
         (unless Indemnitee shall request that such selection be made by the
         Board, in which event the preceding sentence shall apply), and
         Indemnitee shall give written notice to the Corporation advising it of
         the identity of the Independent Counsel so selected. In either event,
         Indemnitee or the Corporation, as the case may be, may, within seven
         (7) days after such written notice of selection shall have been given,
         deliver to the Corporation or to Indemnitee, as the case may be, a
         written objection to such selection. Such objection may be asserted
         only on the ground that the Independent Counsel so selected does not
         meet the requirement of "Independent Counsel" as defined in Section 15
         of this Agreement, and the objection shall set forth with particularly
         the factual basis of such assertion. If such written objection is made,
         the Independent Counsel so selected may not serve as Independent
         Counsel unless and until a court has determined that such objection is
         without merit. If, within twenty (20) days after submission by
         Indemnitee of a written request for indemnification pursuant to Section
         8(a) of this Agreement, no Independent Counsel shall have been selected
         or, if selected, shall have been objected to, in accordance with this
         Section 8(c), either the Corporation or Indemnitee may petition the
         Court of Chancery of the State of Delaware or other court or competent
         jurisdiction for resolution of any objection that shall have been made
         by the Corporation or Indemnitee to the other's selection of
         Independent Counsel of a person selected by the Court or by such other
         person as the Court shall designate, and the person with respect to
         whom an objection is favorably resolved or the person as so appointed
         shall act as Independent Counsel under Section 8(b) of this Agreement.
         The Corporation shall pay any and all reasonable fees and expenses of
         Independent Counsel incurred by such Independent Counsel in connection
         with acting pursuant to Section 8(b) of this Agreement, and the
         Corporation shall pay all reasonable fees and expenses incident to the
         procedures of this Section 8(c), regardless of the manner in which such
         Independent Counsel was selected or appointed. Upon the due
         commencement of any judicial proceeding or arbitration pursuant to
         Section 10(a)(iii) of this Agreement, Independent Counsel shall be
         discharged and relieved of any further responsibility in such capacity
         (subject to the applicable standards of professional conduct then
         prevailing).

         9. PRESUMPTIONS AND EFFECT OF CERTAIN PROCEEDINGS.

         (a) If a Change of Control shall have occurred, in making a
         determination with respect to entitlement to indemnification hereunder,
         the person, persons or entity making such determination shall presume
         that Indemnitee is entitled to indemnification under this Agreement if
         Indemnitee has submitted a request for indemnification in accordance
         with Section 8(a) of this Agreement, and the Corporation shall have the
         burden of proof to overcome that presumption in connection with the
         making by any person, persons or entity of any determination contrary
         to that presumption.

         (b) If the person, persons or entity empowered or selected under
         Section 7 of this Agreement to determine whether Indemnitee is entitled
         to indemnification shall not have made such determination within sixty
         (60) days after receipt by the Corporation of the request therefor, the
         requisite determination of entitlement to indemnification shall be
         deemed to have been made and Indemnitee shall be entitled to such
         indemnification, absent (i) a misstatement by Indemnitee of a material
         fact, or an omission of a material fact necessary to make Indemnitee's
         statement not materially misleading, in connection with the request for
         indemnification, or (ii) a prohibition of such indemnification under
         applicable law; provided, however, that such sixty-day period may be
         extended for a reasonable time, not to exceed an additional thirty (30)
         days, if the person, persons or entity making the determination with
         respect to entitlement to indemnification in good faith requires such
         additional time for the obtaining or evaluating of documentation and/or
         information relating thereto; and provided, further, that the foregoing
         provisions of this Section 8(b) shall not apply (i) if the
         determination of entitlement to indemnification is to be made by the
         stockholders pursuant to Section 8(b) of this Agreement and if (A)
         within fifteen (15) days after receipt by the Corporation of the
         request such determination the Board has resolved to submit such
         determination to the stockholders for their consideration at an annual
         meeting thereof to be held within seventy-five (75) days after such
         receipt and such determination is made threat, or (B) a special meeting
         of stockholders is called within fifteen (15) days after such receipt
         for the purpose of making such determination, such meeting is held for
         such purpose within sixty (60) days after having been so called and
         such determination of entitlement is made thereat, or (ii) if the
         determination of entitlement to indemnification is to be made by
         Independent Counsel pursuant to Section 8(b) of this Agreement.

         (c) The termination of any Proceeding or of any claim, issue or matter
         therein by judgment, order, settlement or conviction, shall not (except
         as otherwise expressly provided in this Agreement) of itself adversely
         affect the right of

                                       7
<PAGE>

         Indemnitee to indemnification hereunder or create a presumption that
         Indemnitee did not act in good faith and in a manner that he reasonably
         believed to be in or not opposed to the best interests of the
         Corporation or, with respect to any criminal Proceeding, that
         Indemnitee had reasonable cause to believe that his conduct wads
         unlawful.

         (d) For purposes of any determination of good faith hereunder,
         Indemnitee shall be deemed to have acted in good faith if in taking
         such action Indemnitee relied on the records or books of account of the
         Corporation, including financial statements, or on information supplied
         to Indemnitee by the officers of the Corporation in the course of their
         duties, or on the advice of legal counsel for the Corporation or on
         information or records given or reports made to the Corporation by an
         independent certified public accountant or by an appraiser or other
         expert selected with reasonable care to the Corporation. The
         Corporation shall have the burden of establishing the absence of good
         faith. The provisions of this Section 9(d) shall not be deemed to be
         exclusive or to limit in any way the other circumstances in which
         Indemnitee may be deemed to have met the applicable standard of conduct
         set forth in this Agreement.

         (e) The knowledge and/or actions, or failure to act, of any other
         director, officer, agent or employee of the Corporation shall not be
         imputed to Indemnitee for purposes of determining the right to
         indemnification under this Agreement.

         10. REMEDIES OF INDEMNITEE.

         (a) If (i) a determination is made pursuant to Section 8 of this
         Agreement that Indemnitee is not entitled to indemnification under this
         Agreement, (ii) advancement of Expenses is not timely made pursuant to
         Section 7 of this Agreement, (iii) the determination of entitlement to
         indemnification is to be made by Independent Counsel pursuant to
         Section 8(b) of this Agreement and such determination shall not have
         been made and delivered in a written opinion within ninety (90) days
         after receipt by the Corporation of the request for indemnification,
         (iv) payment of indemnification is not made pursuant to Section 5 of
         this Agreement within ten (10) days after receipt by the Corporation of
         a written request therefor or (v) payment of indemnification or such
         determination is deemed to have been made pursuant to Section 9 of this
         Agreement, Indemnitee shall be entitled to a final adjudication in an
         appropriate court of the State of Delaware, or in any other court of
         competent jurisdiction, of his entitlement to such indemnification or
         advancement of Expenses. Alternatively, Indemnitee, at his option, may
         seek an award in arbitration to be conducted by a single arbitrator,
         which arbitrator shall be a member of the bar in the State of Illinois,
         pursuant to the rules of the American Arbitration Association.
         Indemnitee shall commence such proceeding seeking an adjudication or an

                                       8
<PAGE>

         award in arbitration within 180 days following the date on which
         Indemnitee first has the right to commence such proceeding pursuant to
         this Section 10(a). The Corporation shall not oppose Indemnitee's right
         to any such adjudication or award in arbitration.

         (b) In the event that a determination shall have been made pursuant to
         Section 8 of this Agreement that Indemnitee is not entitled to
         indemnification, any judicial proceeding or arbitration commenced
         pursuant to this Section 10 shall be conducted in all respects as a de
         novo trial, or arbitration, on the merits and Indemnitee shall not be
         prejudiced by reason of that adverse determination. Regardless of
         whether a Change of Control shall have occurred, in any judicial
         proceeding or arbitration commenced pursuant to this Section 9 the
         Corporation shall have the burden of proving that Indemnitee is not
         entitled to indemnification or advancement of Expenses, as the case may
         be.

         (c) If a determination shall have been made or deemed to have been made
         pursuant to Section 8 or 9 of this Agreement that Indemnitee is
         entitled to indemnification, the Corporation shall be bound by such
         determination in any judicial proceeding or arbitration commenced
         pursuant to this Section 10, absent (i) a misstatement by Indemnitee of
         a material fact, or an omission of a material fact necessary to make
         Indemnitee's statement not materially misleading, in connection with
         the request for indemnification or (ii) a prohibition of such
         indemnification under applicable law.

(c)      The Corporation shall be precluded from asserting in any judicial
         proceeding or arbitration commenced pursuant to this Section 10 that
         the procedures and presumptions of this Agreement are not valid,
         binding and enforceable and shall stipulate in any such court or before
         any such arbitrator that the Corporation is bound by all the provisions
         of this Agreement.

         (d) If Indemnitee, pursuant to this Section 10, seeks a judicial
         adjudication of or an award in arbitration to enforce his rights under,
         or to recover damages for breach of, this Agreement, Indemnitee shall
         be entitled to recover from the Corporation, and shall be indemnified
         by the Corporation against, any and all expenses (of the types
         described in the definition of Expenses in Section 14 of this
         Agreement) actually and reasonably incurred by him in such judicial
         adjudication or arbitration, but only if he prevails therein. If it
         shall be determined in said judicial adjudication or arbitration that
         Indemnitee is entitled to receive part but not all of the
         indemnification or advancement of Expenses sought, the expenses
         incurred by Indemnitee in connection with such judicial adjudication or
         arbitration shall be appropriately prorated.

         11. SECURITY

         (a) To the extent requested by the Indemnitee and approved by the
         Board, the Corporation may at any time and from time to time provide
         security to the Indemnitee for the Corporation's obligations hereunder
         through an irrevocable bank line of credit, funded trust or other
         collateral. Any such security, once provided to the Indemnitee, may not
         be revoked or released without the prior written consent of Indemnitee.

         (b) For each Proceeding in which Indemnitee is entitled to
         indemnification, the Corporation, at the time such Proceeding is
         commenced, shall deposit a minimum of One Million Dollars ($1,000,000)
         in an escrow account to fund any Losses or Expenses for or on behalf of
         Indemnitee pursuant to this Agreement. In the event a single Proceeding
         involves more than one Indemnitee, only one such escrow account shall
         be established with respect to such Proceeding. The Corporation shall
         maintain a minimum balance in each such escrow account of One Million
         Dollars ($1,000,000) and shall increase such amount from time to time
         as it shall deem necessary or desirable to meet the Corporation's
         anticipated obligations in connection with such Proceeding, pursuant to
         this Agreement. The amount deposited by the Corporation in any such
         escrow account shall not limit the Corporation's liability under this
         Agreement. At the termination of any such Proceeding, after payment of
         all Losses and Expenses, judgments, fines or settlement amounts, the
         balance of funds remaining in the escrow account established for such
         Proceeding shall be returned to the Corporation for its general
         purposes and such escrow account shall be closed.

         12. NON-EXCLUSIVITY; DURATION OF AGREEMENT; INSURANCE; SUBROGATION.

         (a) The rights of indemnification and to receive advancement of
         Expenses as provided by this Agreement shall not be deemed exclusive at
         any other rights to which Indemnitee may at any time be entitled under
         applicable law, the Corporation's certificate of incorporation or
         bylaws, any other agreement, a vote of stockholders or a resolution of
         directors, or otherwise both as to action in Indemnitee's official
         capacity and as to action in another capacity while holding such
         office. To the extent Indemnitee would be prejudiced thereby, no
         amendment, alteration, rescission or replacement of this Agreement or
         any provision hereof shall be effective as to Indemnitee with respect
         to any action taken or omitted by such Indemnitee in Indemnitee's
         position with the Corporation or any other entity which Indemnitee is
         or was serving at the request of the Corporation prior to such
         amendment, alteration, rescission or replacement. This Agreement shall
         continue until and terminate upon the latter of: (a) ten (10) years
         after the date that Indemnitee shall have ceased to serve as

                                       10
<PAGE>

         a director and officer of the Corporation or as an officer, employee,
         agent or fiduciary of the Corporation or of any other corporation,
         partnership, joint venture, trust, employee benefit plan or other
         enterprise that Indemnitee served at the request of the Corporation; or
         (b) one year after the final termination of all pending or threatened
         Proceedings in respect of which Indemnitee is granted rights of
         indemnification or advancement of Expenses hereunder and of any
         proceeding commenced by Indemnitee pursuant to Section 9 of this
         Agreement relating thereto. This Agreement shall be binding upon the
         Corporation and its successors and assigns and shall inure to the
         benefit of Indemnitee and his heirs, executors and administrators.

         (b) If the Corporation maintains an insurance policy or policies
         providing liability insurance for directors or officers of the
         Corporation of fiduciaries of any other corporation, partnership, joint
         venture, trust, employee benefit plan or other enterprise that such
         person serves at the request of the Corporation, Indemnitee shall be
         covered by such policy or policies in accordance with the terms thereof
         to the maximum extent of the coverage available for any such director
         or officer under such policy or policies.

         (c) If any payment is made under this Agreement, the Corporation shall
         be subrogated to the extent of such payment to all of the rights of
         recovery of Indemnitee, who shall execute all papers required and take
         all action necessary to secure such rights, including execution of such
         documents as are necessary to enable the Corporation to bring suit to
         enforce such rights.

         (d) The Corporation shall not be liable under this Agreement to make
         any payment of amounts otherwise indemnifiable hereunder if and to the
         extent that Indemnitee has otherwise actually received such payment
         (net of Expenses incurred in collecting such payment) under any
         insurance policy, contact, agreement or otherwise.

         13. SEVERABILITY. If any provision or provisions of this Agreement
shall be held to be invalid, illegal or unenforceable for any reason whatsoever
(a) the validity, legality and enforceability of the remaining provisions of
this Agreement (including, without limitation, each portion of any Section of
this Agreement containing any such provision held to invalid, illegal or
unenforceable, that is not itself invalid, illegal or unenforceable) shall not
in any way be affected or impaired thereby; and (b) to the fullest extent
possible, the provisions of this Agreement (including, without limitation, each
portion of any Section of this Agreement containing any such provision held to
be invalid, illegal or unenforceable, that is not itself invalid, illegal or
unenforceable) shall be construed so as to give effect to the intent manifested
by the provision held invalid, illegal or unenforceable.

         14. EXCEPTION TO RIGHT OF INDEMNIFICATION OR ADVANCEMENT OF EXPENSES.
Notwithstanding any other provision of this Agreement, Indemnitee shall not be
entitled to indemnification or advancement of Expenses under this Agreement with
respect to any Proceeding, or any claim, issue or matter therein, brought or

                  THE PLAN. The Company established the Plan, effective March 6,
1990 (the "Effective Date"). The Company hereby amends and restates the Plan,
effective May 30, 1990. Such establishment of the Plan, as so amended and

It is anticipated that the acquisitions of such a financial interest will
stimulate the efforts of such employees on behalf of the Company and its
subsidiaries and strengthen their desire to continue in the service of the
Company and its subsidiaries. It is also anticipated that the opportunity to
obtain such a financial interest will prove attractive to promising executive
talent and will assist the Company and its subsidiaries in attracting such

granted additional options or change of control rights if the Committee shall so
determine. Subject to the other provisions of the Plan, the Committee may grant
options or change of control rights with differing terms and conditions among
the Grantees. To the extent not set forth in the Plan, the terms and conditions
of each grant of an option or change of control rights shall be set forth in a
written agreement between the Company and the Grantee thereof.

with change of control rights is exercised, the number of the change of control
rights equal in number to the shares of Stock purchased shall be canceled.

         the Grantee during any such calendar year with respect to Stock which
         would have an aggregate Fair Market Value (determined at the time of
         each such grant) in excess of the $100,000 Limit shall, notwithstanding
         the terms of the Current Grant, be exercisable for the first time by
         the Grantee in the first subsequent calendar year or years in which it

<PAGE>

                  (ii) if, viewed as of the date of the Current Grant, any

         of the immediately preceding sentence during any calendar year
         commencing with the calendar year in which it is first exercisable
         through and including the last calendar year in which it may by its
         terms be exercised, such portion of the Current Grant shall not be an
         incentive stock option, but shall be exercisable as a separate
         non-qualified option at such date or dates as are provided in the
         Current Grant;

                  (6) shall be granted within ten (10) years from the earlier of

rights shall automatically be granted to each Grantee upon the grant of any
non-qualified option under the Plan. Each change of control right shall be
identified with a share of Stock subject to the non-qualified option of the
Grantee and the number of change of control rights granted to a Grantee shall
equal the number of shares of Stock subject to the option with which such change
of control rights are identified. At the time change of control rights of the
Grantee are exercised, a number of shares of Stock subject to the option equal
in number to the change of control rights exercised shall be canceled.

                  (d) NON-TRANSFERABILITY OF OPTIONS AND CHANGE OF CONTROL
RIGHTS. An option or change of control right granted hereunder shall, by its
terms, not be assignable or transferable other than by will or the laws of
descent and distribution and may be exercised, during his lifetime, only by the
Grantee.

each option of change of control right granted hereunder shall be for a period
of no more than ten years from the Grant Date, and shall be subject to earlier
termination as herein provided.

concert, of a beneficial ownership interest in the Company, resulting in the
total beneficial ownership of such persons or group of persons equaling or
exceeding 50% of the outstanding common stock and warrants of the Company;
provided, however, that no such person or group of persons shall be deemed to
beneficially own (i) any common stock or warrants acquired directly from the
Company or (ii) any common stock or warrants held by the Company or any of its
subsidiaries or any employee benefit plan (or any related trust) of the Company
or its subsidiaries. The Change of Control shall be deemed to occur on the date
the beneficial ownership of the acquiring person or group of persons first
equals or exceeds 50% of the outstanding common stock and warrants of the
Company.

                  (b) A change, within any period of twenty-four (24) months or
less, in the composition of the Board such that at the end of such period a
majority of the directors who are then serving were not serving at the beginning
of such period, unless at the end of such period the majority of the directors
in office were nominated upon the recommendation of a majority of the Board at
the beginning of such period. The Change of Control shall be deemed to occur on
the date the last director necessary to result in a Change of Control takes
office or resigns from office, as applicable.

immediately prior to such event do not, following such event, beneficially own,
directly or indirectly, more than 50% of, respectively, the then outstanding
voting securities of the corporation resulting from such event or the
corporation purchasing or receiving assets pursuant to such event. The Change of
Control shall be deemed to occur on the date on which the transaction is
approved by the Company's Securityholders.

                  If more than one of the foregoing events shall occur, each
such event shall constitute a separate Change of Control.

                  Notwithstanding the foregoing provisions of this Paragraph 6,
a Change of Control shall be deemed not to have occurred with respect to any
event occurring prior to or concurrently with the securityholders' approval of
this Plan.

                  The impact on the Plan of a Change of Control shall be (1) the
acceleration. of the exercisability of options and change of control rights as
provided in Paragraphs 7(b) and (c) and (2) the use for determining the benefit
payable upon exercise of change of control rights of the definition of Fair
Market Value contained on Paragraph 1(g)(3).

<PAGE>

                  The Company shall notify all Grantees of the occurrence of a
Change of Control promptly after its occurrence, but any failure of the Company
to notify shall not deprive the Grantees of any rights accruing hereunder by
virtue of a Change of Control.

</TABLE>

                  Options shall be exercised by delivery to the Company of
written notice of intent to purchase a specific number of shares of stock. The
exercise of a non-qualified option shall cancel a number of change of control
rights identified with such option equal to the number of shares of Stock
purchased upon exercise of the option. The Option Price of any shares of Stock
as to which an option shall be exercised shall be paid in full at the time of
the exercise. Payment of the Option Price shall be made (1) in cash or (2) in
whole or in part, in Stock of the Company held by the Grantee for a period of at
least six months, valued at Fair Market Value.

                  Notwithstanding the foregoing, if the Grantee's employment is
terminated by the Grantee's retirement pursuant to the terms of any
tax-qualified retirement plan of the Company or any of its subsidiaries, or by
the Disability or death of the Grantee, any unexercised options held by the
Grantee on the date of such retirement, Disability or death shall become
immediately exercisable.

                  (b) EXERCISE OF CHANGE OF CONTROL RIGHTS. Subject to the
provisions of Paragraph 8, each change of control right held by a Grantee who is
subject to potential liability for "short-swing" profits under Section 16(b) of
the 1934 Act at the time of a Change of Control shall become exercisable upon
the occurrence of the Change of Control. No change of control right held by any
Grantee who is not subject to potential liability for "short-swing" profits
under Section 16(b) of the 1934 Act at the time of a Change of Control shall
become exercisable upon the occurrence of the Change of Control. The exercise of
change of control rights shall cancel a number of shares of Stock subject to the
option identified with such change of control rights equal to the number of
change of control rights exercised. Change of control rights shall be exercised
by delivery to the Company, within sixty (60) days following the date of such
Change of Control, of written notice of intent to exercise a specific number of
change of control rights.

<PAGE>

                  Within three (3) days following the exercise of any change of
control right, the Company shall pay the Grantee, in cash, an amount equal to
the difference between

                  (1) the Fair Market Value of one share of Stock on the date of
exercise of the change of control right, and

                  (2) the Option Price of the option identified with the change
of control right.

                  (c) ACCELERATED EXERCISE. subject to Paragraph 7(g), all
outstanding options granted hereunder shall be fully exercisable on the date of
a Change of Control.

                  (d) WITHHOLDING TAXES. Whenever under the Plan, shares of
Stock are to be delivered upon exercise of an option the Company shall be
entitled to require as a condition of delivery that the Grantee remit an amount
sufficient to satisfy all federal, state, and other governmental withholding tax
requirements related thereto. A Grantee may, subject to Committee approval,
elect the withholding ("Share Withholding") by the Company of a portion of the
shares of Stock otherwise deliverable to such Grantee upon such Grantee's
exercise of an option having a Fair Market Value equal to

                  (1) the amount necessary to satisfy such Grantee's required
federal, state, or other governmental withholding tax liability with respect to
the exercise of the option, or

                  (2) a greater amount, not to exceed the estimated total amount
such Grantee's tax liability with respect to the exercise of the option.

                  Share Withholding is subject to Committee approval. Each Share
Withholding election by a Grantee shall be subject to the following
restrictions.

                  (1) it shall be made prior to the date on which the amount of
tax to be withheld is determined (the "Tax Date");

                  (2) it shall be irrevocable;

                  (3) it shall be subject to the disapproval of the Committee;

                  (4) if a Grantee is subject to potential liability for
"short-swing" profits under Section 16(b) of the 1934 Act, such election may not
be made within six (6) months after the Grant Date of the related option (except
that this limitation shall not apply if the death or Disability of the
participant occurs prior to the expiration of the six-month period or if, in the
opinion of counsel for the Company, such limitation is unnecessary to satisfy
the requirements of Rule 16B-3 under Section 16(b) of the 1934 Act or the rules
of any exchange on which the Stock is listed for trading; and

                                       9
<PAGE>

                  (5) If a Grantee is subject to potential liability for
"short-swing" profits under Section 16(b) of the 1934 Act, such election must he
made either six (6) months prior to the Tax Date or in the ten business day
"window period" beginning on the third business day following the release of the
Company's quarterly or annual summary statement of sales and earnings, unless,
in the opinion of counsel for the Company, such limitation is unnecessary to
satisfy the requirements of Rule 16b-3 under Section 16(b) of the 1934 Act or
the rules of any exchange on which the Stock is listed for trading.

                  If any disqualifying disposition described in Paragraph 5(b),
(7) or any election described in Paragraph 7(e) is made, then the person making
such disposition or election shall remit to the Company an amount sufficient to
satisfy all federal, state, and other governmental withholding taxes thereby
incurred; provided that, in lieu of or in addition to the foregoing, the Company
shall have the right to withhold such sums from compensation otherwise due to
such person.

                  (e) NOTIFICATION UNDER SECTION 83(b). Provided that the
Committee does not prohibit such Grantee from making the following election, if
a Grantee shall in connection with the exercise of any option make the election
permitted under Section 83(b) of the Code (i.e., an election to include in such
Grantee's gross income in the year of transfer the amount specified in section
83(b) of the Code), then such Grantee shall notify the committee of such
election within ten (10) days of filing notice of the election with the Internal
Revenue Service, in addition to any filing and notification required pursuant to
regulations issued under the authority of Section 83(b) of the Code.

                  (f) STOCK PURCHASED FOR INVESTMENT. Shares of Stock purchased
under an option shall be purchased for investment and without present intention
of resale and the certificates representing such Stock shall bear an appropriate
legend, unless, in the opinion of counsel for the Company, the shares may be
purchased without investment representation. Where an investment representation
is deemed necessary, the Committee may require a written representation to that
effect by the Grantee at the time the option is exercised.

                  (g) SPECIAL RULES FOR OFFICERS AND DIRECTORS. No officer or
director shall exercise an option identified with change of control rights or
change of control rights for six months from the Grant Date of such options or
change of control rights except that this limitation shall not apply in the
event the death or Disability of the Grantee occurs prior to the expiration of
the six-month period or if, in the opinion of counsel for the Company, such
limitation is unnecessary to satisfy the requirements of Rule 16b-3 under
Section 16(b) of the 1934 Act or the rules of any exchange on which the Stock is
listed for trading.

<PAGE>

                  8. TERMINATION OF EMPLOYMENT. Except as provided below or as
determined by the Committee, an unexercised option shall terminate upon the
Grantee's termination of employment. Termination of employment means the first
date the Grantee is no longer an employee of the Company or any of its
subsidiaries or, with respect to a Grantee who is an employee of a subsidiary of
the Company, on the first date on which the Company no longer (directly or
indirectly) owns shares of stock conferring at least fifty percent (50%) of the
aggregate voting power of such subsidiary's outstanding stock (both events
hereunder are referred to as "termination of employment").

                  (a) Except as provided in (b) and (c), any unexercised options
previously granted to the Grantee and otherwise exercisable on such Grantee's
termination of employment may be exercised, in whole or in part, at any time
within six months after the Grantee's termination of employment

                  (b) If such employment is terminated by death of the Grantee,
any unexercised options on the date of death may be exercised, in whole or in
part, at any time within 18 months after the date of death by the Grantee's
personal representative or by the person to whom the option is transferred by
will or the applicable laws of descent and distribution; and

                  (c) If such employment is terminated by reason of the
Grantee's retirement pursuant to the terms of any tax-qualified retirement plan
of the Company or any of its subsidiaries or Disability of the Grantee, any
unexercised options on the date of such retirement or Disability may be
exercised, in whole or in part, at any time within 18 months after date of such
termination of employment, provided that, if such person dies after such
termination of employment, and before the expiration of the 18-month period,
such options may be exercised by the deceased Grantee's personal representative
or by the person to whom the options are transferred by will or the applicable
laws of descent and distribution within such 18-month period.

                  Any unexercised change of control right exercisable on the
Grantee's termination of employment shall remain exercisable until the end of
the sixty-day period provided for in Paragraph 7(b).

                  Any of the provisions of this Paragraph 8 to the contrary
notwithstanding, in no event shall any option or change of control right be
exercised after ten years from the Grant Date.

                  9. NO EMPLOYMENT RIGHTS. Neither the establishment of, nor the
awarding of options or change of control rights under, the Plan shall be
construed to give any employee the right to be retained in the Company's (or any
of its subsidiaries') service or to any benefits not specially provided by the
Plan, or to modify in any manner the Company's right to modify, amend or
terminate any of its pension or retirement plans.

                                       11
<PAGE>

                  10. NATURE OF PAYMENTS. Any and all grants of options or
change of control rights or deliveries of shares of Stock hereunder shall
constitute special incentive payments to the Grantee and shall not be taken into
account in computing the amount of salary or compensation of the Grantee for the
purposes of determining any pension, retirement, death or other benefits under
(a) any pension, retirement, profit-sharing, bonus, life insurance or other
employee benefit plan of the Company or any of its Subsidiaries, or (b) any
agreement between the Company or any of its subsidiaries and the Grantee, except
as such plan or agreement shall otherwise expressly provide.

                  11. STOCKHOLDERS' RIGHTS. A Grantee shall not, by reason of
any options or change of control rights granted hereunder, have any right of a
stockholder of the Company with respect to the shares of Stock subject to his
options.

                  12. ADJUSTMENTS. Any option agreement or change of control
rights agreement entered into hereunder shall contain provisions for equitable
adjustment of

                  (a) the number, class, and series of shares of stock subject
thereto, or

                  (b) the Option Prices,

to reflect a stock dividend, stock split-up, share combination,
recapitalization, merger, consolidation, asset spin-off, reorganization, or
similar event, of or by the Company. In any such event, regardless of whether
specified in an option agreement or change of control rights agreement, the
aggregate number, class and series of shares of stock and change of control
rights available under the Plan, the number, class and series of shares of stock
subject to the option agreement, or the Option Price shall be appropriately
adjusted to equitably reflect such event.

                  13. AMENDMENT OF THE PLAN. The Board may not amend the Plan
without further approval of the securityholders of the Company, unless, in the
opinion of counsel for the Company, such approval is unnecessary to satisfy the
requirements of Rule 16B-3 under Section 16(b) of the 1934 Act or the rules of
any exchange on which the Stock is listed for trading and except as provided in
Paragraph 12.

                  14. TERMINATION OF THE PLAN. The Plan shall terminate ten
years after the Effective Date, or at such earlier time as the Board may
determine. Any termination, whether in whole or in part, shall not effect any
options or change of control rights then outstanding under the Plan.

                  15. SUBSTITUTED OPTIONS. If the Committee cancels, with the
consent of a Grantee, any options granted under this Plan, and a new option is
substituted therefor, then the Committee may, in its discretion, provide that
the Grant Date of the canceled option (other than an option subject to the
restrictions of paragraph 5(b)), shall (subject to

                                       12
<PAGE>

the provisions of Paragraph 7(g)) be the date used to determine the earliest
date for exercising the new substituted option under Paragraph 7 so that the
Grantee may exercise the substituted option at the same time as if the Grantee
had held the substituted option since the Grantee Date of the canceled option.

                  16. FUNDING. Benefits payable under the Plan to any person
shall be paid directly by the Company. The Company shall not be required to
fund, or otherwise segregate assets to be used for payment of, benefits under
the Plan.

                  17. CONTROLLING LAW. The law of the State of Illinois, except
its law with respect to choice of law, shall be controlling in all matters
relating to the Plan.

                  18. ACTION BY THE COMPANY. Any action required by the Company
under the Plan shall be by resolution of the Board.

          progress or other payments, or acknowledge receipt of any equipment
          until successful completion of all applicable Acceptance Test
          Procedures as defined in Rider H.

     E.   The Commonwealth may, at its option, accept a Site or Subsystem prior
          to successful completion of Acceptance Testing, recognizing that some
          discrepancies exist. These discrepancies shall be compiled and listed
          at the time of Acceptance Testing and acknowledged by the contractor
          on what is commonly referred to as a "punch list". Before the
          Commonwealth shall exercise this option, an agreement in writing shall
          be established between the Commonwealth and the contractor stating
          that the contractor shall make all corrections noted on the punch list
          by the date agreed to. If the contractor fails to make correction of
          all deficiencies noted on the punch list on the date specified, the
          Commonwealth may take appropriate legal action against the contractor,
          and the surety company under the performance bond, for damages
          incurred by the Commonwealth.

     F.   If successful completion of repeated Acceptance Testing is not
          attained within one hundred twenty (120) days of the Installation
          Date, the Commonwealth shall have the option of terminating this
          Contract, or continuing repeated Acceptance Tests. The Commonwealth's
          option to terminate this Contract shall remain in effect until such
          time as a successful completion of the Acceptance Testing is attained.
          If termination occurs, the Contractor shall be liable for all inbound
          and outbound preparation and shipping costs for contracted items
          returned.

     G.   After a Site or Subsystem has completed a successful Acceptance Test,
          a Site or Subsystem which:

<PAGE>

          i.   is field modified from one model to another; or,

          ii.  is installed as a Replacement by the Contractor,

          shall be subject to a new original Acceptance Test, which shall be in
          accordance with the provisions of this paragraph, but independently of
          other Sites or Subsystems in the System. The Commonwealth and the
          Contractor jointly shall maintain appropriate records to satisfy the
          requirements of this paragraph.

A.13 LIQUIDATED DAMAGES

     A.   The installation dates set forth in the SDOs will be fixed in such a
          manner that the integration of the System is consistent with the
          timing and schedules of the Commonwealth's programs. If the Contractor
          does not complete Installations within the time limits specified in
          the SDOs, the delays will interfere with the proper implementation of
          the Commonwealth's System and with coordination between the various
          contractors installing the system to the loss and damage of the
          Commonwealth. From the nature of the case it would be impractical and
          extremely difficult to fix the actual damage sustained in the event of
          any such action. The Commonwealth and the Contractor, therefore,
          presume that in the event of any such delay the amount of damage
          sustained from the delay will be the amount set forth in this
          paragraph. They further agree that in the event of any such delay, the
          Contractor shall pay such amount as liquidated damages and not as a
          penalty; and that such liquidated damages are in lieu of all other
          damages arising from such delay. The Commonwealth is not obligated for
          payment of liquidated damages under the terms of this Contract.

<PAGE>

     B.   If the Contractor does not meet the Installation Date(s) of the
          SDO(s), the Contractor shall pay the Commonwealth, as fixed and agreed
          liquidated damages for each calendar day between the required
          Installation Date and the actual Installation Date, but not for more
          than one hundred eighty (180) calendar days in any instance, in lieu
          of all other damages due to such non-installation, an amount of 0.05%
          (0.0005) daily of the purchase price including maintenance, but less
          the purchase price applicable to installed Components, for each
          Subsystem rendered inoperable as a result of such delay in Ready for
          Use.

     C.   Delays of the contractor in meeting scheduled Installation Date for a
          Site, a Subsystem, or the System as specified in the SDO shall result
          in a loss to the Commonwealth of 0.05% (0.0005) per day of the
          purchase price, for a maximum of 180 working days for each subsystem
          rendered inoperable as a result of each calendar day delay in
          completing the tasks. An extension of time granted by the Commonwealth
          shall not be construed as a waiver of liquidated damages unless such
          extension shall specifically provide such waiver.

     D.   If the delays are caused by a subcontractor, and if such delay arises
          out of causes beyond the control of both the Contractor and
          subcontractor, and without the fault or negligence of any of them, the
          Contractor shall not be liable for liquidated damages for delays,
          unless the Equipment or Services to be furnished by the Contractor or
          Subcontractor were obtainable from other sources in sufficient time to
          permit the Contractor to meet the required Installation Date.

     E.   The Commonwealth shall have the option of billing the Contractor or
          deducting from any invoice an amount equal to the above as liquidated
          damages or waiting for the Contractor's certification so the
          Acceptance Testing can begin.

     F.   If the delay of installation of any Equipment is more than thirty (30)
          calendar days, then during that or the subsequent thirty (30) day
          period the Contractor may elect to install substitute Equipment,
          acceptable to the Commonwealth, of at least equal capabilities (or
          greater capabilities at the Contractor's option) and capable of
          performing the functions of such Equipment, as specified in the
          manufacturer's published specifications for the Equipment and the
          Commonwealth's required functions and features. If the Contractor does
          not elect to install substitute Equipment during either such period,
          then by written notice to the Contractor, the Commonwealth may
          terminate the right of the Contractor to install such original or such
          substitute Equipment, and may obtain other Equipment in place thereof.
          The Commonwealth is not liable for any packing, unpacking, drayage,
          rigging, shipping and installation charges for any of the Contractor's
          substitute Equipment.

     G.   If some, but not all, of the System or a Subsystem is Ready For Use by
          the required date, and the Commonwealth uses for operational purposes
          any such installed Subsystem, liquidated damages shall not accrue
          against the Subsystem used.

     H.   If the delays are caused by the Engineering and Quality Assurance
          Contractor, the Site

<PAGE>

          Development contractor or the Microwave contractor, the delay shall be
          handled in the same manner as a delay in Site availability and
          liquidated damages shall not apply.

A.14 NEED FOR EQUIPMENT DUE TO EMERGENCY

     A.   For a period of two (2) years after System Acceptance, the Contractor
          shall make reasonable efforts to assist the Commonwealth in procuring
          use of Equipment compatible with that used by the Commonwealth to meet
          emergencies such as, but not limited to, major breakdowns and
          unforeseen incidents.

     B.   The Commonwealth, at its option, may accept or reject the offer of use
          of emergency Equipment. If accepted, the charge for such use, if any,
          shall be by separate arrangement between the Commonwealth and the
          entity providing the emergency Equipment.

     C.   Contractor shall make available spare parts and service support for
          all equipment supplied under this procurement for a minimum of 10
          years from the date of execution of the contract. Contractor agrees to
          supply the Commonwealth with written notification of the
          discontinuance of production of any Contractor-manufactured hardware
          or equipment no later than 1 year prior to discontinuance.

A.15 ALTERATIONS AND INTERCONNECTIONS

     A.   The Commonwealth may make Alterations or install Interconnections to
          Sites, Subsystems, Equipment or Components at the Commonwealth's

          Contractor:

          i.   The Commonwealth shall be responsible for damage to the System
               caused by or resulting from such Alterations or Interconnections;

          ii.  The Contractor shall not be held responsible for any defects or
               malfunctions or non-conformance caused by or resulting from such
               Alterations or Attachments;

          iii. The Commonwealth shall pay the Contractor for any increase in the
               cost of effort related to maintenance service for the System,
               caused by or resulting from such Alterations or Interconnections;

          iv.  Such Alterations or Interconnections shall be removed and the
               Equipment restored to the prior configuration at the
               Commonwealth's expense upon return of the Equipment to the
               Contractor; and

          v.   There shall be no effect on the Contractor under this Contract as
               a result of such Alterations or Interconnections, whether for
               warranty, time of performance or other purposes.

A.16 TRAINING AND TECHNICAL SERVICES

          Commonwealth at the Contractor's then standard terms and charges.

A.17 ASSIGNED PERSONNEL

     A.   The Contractor shall provide to the Commonwealth a summary of
          technical qualifications for each individual assigned to the
          Commonwealth at the Commonwealth's location in support of this
          contract. The Commonwealth must approve the selection of these
          personnel in advance of their assignment to this project.

     B.   Contractor agrees that key personnel, including management,
          engineering, and supervisory, assigned to the project shall remain
          assigned to the project unless terminated or due to unforeseen
          circumstances.

     C.   In the event of termination or unforeseen circumstances, substitutes
          for assigned personnel shall be approved in advance by the
          Commonwealth, shall have comparable levels of responsibility and
          authority, and shall have substantially equivalent experience and
          skill. Contractor agrees to make available for interview purposes any
          individuals proposed for this project, and agrees to supply the
          Commonwealth with resume, work history, or other requested
          documentation supporting the contractor's proposed assignment or
          substitution. The Commonwealth reserves the right to accept or reject
          any or all individuals recommended for project assignment.

A.18 SITE PREPARATION

     A.   The Contractor will notify the Commonwealth in writing as to the
          adequacy of the Commonwealth's planned layout of each Site for the
          Equipment within thirty (30) days after receipt of the Commonwealth's
          plans. The parties shall mutually agree upon any changes, if a planned
          layout is not adequate. If such agreement is not reached, Paragraph
          A.53 shall be applicable.

     B.   Any Contractor alterations or modifications in Site Preparation, which
          are attributable to incomplete or erroneous investigations,
          calculations, or engineering requirements provided by the Contractor
          and which involve additional expense to the Commonwealth, shall be
          made at the expense of the Contractor.

     C.   If any such alterations as specified in Paragraph C above, cause a
          delay in the installation, the provisions as specified in LIQUIDATED
          DAMAGES paragraph of this Contract will apply in accordance with the
          provision thereof.

     D.   If Commonwealth or federal environmental agencies provide the
          Contractor with guidelines or directives on site preparation, which
          are followed in good faith by the

<PAGE>

               Contractor, and it later proves to be erroneous or incomplete,
               the Commonwealth will pay the additional expense and no
               liquidated damages shall be applicable.

          Commonwealth location to another.

     C.   Relocation of Equipment for the Commonwealth's convenience shall be at
          the Commonwealth's expense. However, if relocation is due to the
          Contractor's improper initial location of Equipment, the Contractor
          shall be liable for relocation, packing and unpacking of Equipment
          without charge to the Commonwealth.

A.20 RISK OF LOSS

The Commonwealth shall be relieved from all risk of loss or damage to the
Equipment while it is at the Contractor's storage and service facilities, when
it is shipped to installation locations, and until the Commonwealth accepts the
System. However, Contractor shall not be responsible for loss or damage caused
by the Commonwealth, its Engineering and Quality Assurance Contractor, the
Microwave System contractor or the Trunked Radio System contractor.

A.21 LAWS AND REGULATIONS

     A.   The attention of Contractor is directed to the federal state and local

     F.   The Commonwealth acknowledges responsibility for integration of the
          System purchased under this Contract and other systems and equipment
          purchased through other related contracts. Contractor agrees to
          provide the Commonwealth with technical support, including engineering
          investigation and research if required, necessary to enable the
          Commonwealth to fully characterize the interface requirements

<PAGE>

          of Contractor's System as needed to complete system integration.

     C.   During the period covered by the Contract, and until the expiration of
          three (3) years after final payment under the Contract, the Contractor
          agrees to provide the Commonwealth, its duly authorized
          representative, and any person, agency or instrumentality providing
          the Commonwealth with financial support to the work undertaken
          hereunder with access to and the right to examine any books,

          quantities of the various items of work actually done or services and
          materials actually furnished, and the quantities indicated in the RFQC
          and Proposal.

     C.   The various parts of the Contract are intended to supplement but not
          necessarily duplicate each other. Any work exhibited in one part and
          not in another shall be performed as if it had been set forth in all
          parts, so that the work will be performed according to the Contract.

     D.   Compensation for all profit and loss, both anticipated and actual,
          shall be considered as fully made in the Contract price(s) contained
          in Rider C.

A.34 OTHER CONTRACTS

     A.   Contractor is advised that this Contract is a part of a larger
          project, and that related contracts may be let accordingly. Contractor
          shall afford other contractors and subcontractors a reasonable
          opportunity for the performance of their work, and shall properly
          coordinate and schedule its work with theirs.

     B.   If a part of Contractor's work depends upon the work of another
          contractor or subcontractors for proper performance and results,
          Contractor shall carefully review and promptly report to the
          Commonwealth in writing any defect or delay in the performance of such
          work that renders it unsuitable for Contractor's proper performance
          and results, or that Contractor believes excuse the full and timely
          performance by Contractor.

A.35 RIGHT OF ENTRY

The Commonwealth reserves the right at any time to enter the property or
location on which the work is to be performed, by such agent or agents, as it
may elect, for the purpose of inspecting the work.

A.36 SAFETY REQUIREMENTS

     A.   All parts of this Contract shall be performed in strict accordance
          with the safety requirements of applicable codes and statues, federal,
          state and local requirements, and the best industry practice.
          Contractor is fully obligated to follow all safety procedures on
          behalf of its Site personnel, Equipment, and properties involved in
          this project, including Contractor's subcontractors, the
          Commonwealth's employees and visitors.

     B.   All work performed by the Contractor at above-ground elevations,
          including work on masts, poles, towers, monopoles, rooftops, chimneys,
          and similar installation sites and antenna support structures, shall
          comply with regulations established by OSHA and with the guidelines
          established by the National Association of Tower Erectors.

A.37 PROTECTION OF PROPERTY AND EQUIPMENT


<PAGE>

     A.   Contractor shall use its best efforts to protect the adjacent or
          adjoining properties and equipment from damage or loss from
          Contractor's operations or its subcontractors' operations. Contractor
          shall bear the costs of damage or loss caused by its operations or
          those of his subcontractors.

     B.   Existing underground installations such as water pipes, oil and gas
          pipelines, sewers, telephone lines, power lines, and buried structures
          in the vicinity of the Work are indicated on the drawings only to the
          extent such information has been made available to or discovered by an
          Architect, Engineer, or the Commonwealth in preparing the drawings.
          There is no guarantee as to the accuracy or completeness of such
          information, and the responsibility for accuracy and completeness is
          expressly disclaimed. Contractor shall be responsible for the location
          and protection of underground installations that are crossed or
          exposed by his design.

     C.   Contractor shall be solely responsible for accurately locating
          existing underground installations in advance of excavating or
          trenching, by contacting their owners and by having the owners locate
          and mark the location of the underground facilities placed within the
          Site. Repair of damage to underground installations for which the
          Contractor is legally responsible shall be paid by the Contractor.

     D.   Delays, additional Work, or extra cost to Contractor caused by
          existing underground installations shall not constitute a claim for
          extra Work, additional payment, damages, or extensions of time. In the
          event that it is determined that existing underground installations
          may cause to be incurred, additional costs, delays, damages, etc.,
          Contractor will notify the Commonwealth to arrange for the appropriate
          disposition. This disposition may include, but not be limited to:
          additional compensation, modification/extension of the Schedule,
          relocation of the applicable Work to another Site, etc.

A.38 HOLD HARMLESS CLAUSE ISSUE

The Contractor shall be responsible for and agrees to indemnify and hold
harmless the Commonwealth from damages to property or personal injuries
(including wrongful death) to any person(s) and from related losses, damages,
expenses, claims, demands, suits and actions arising in connection with the work
performed by the Contractor. The Commonwealth shall give prompt written notice
to Contractor upon Commonwealth becoming aware of or receiving notice of any
matter covered by this Paragraph and Contractor shall have the right to
participate in the defense thereof.

A.39 FORCE MAJEURE

     A.   The term Force Majeure as used herein shall mean any and all causes
          beyond the reasonable control and without any fault or negligence of
          the Party failing to perform, such as action of the elements,
          including floods, tornadoes, or hurricanes, acts of public authorities
          and/or regulatory agencies, including inability to obtain required
          permits or authorizations, acts of public enemy, insurrection, riots,
          strikes, labor and material shortages, fires, explosions, breakdowns
          of or damage to plant, equipment or


<PAGE>

          facilities, interruptions of transportation, embargoes, acts of
          military authorities, or other causes of a similar nature which wholly
          or partly prevent the performance of an obligation under this
          Contract.

     B.   Inclement weather including rain, snow, ice, or conditions resulting
          therefrom shall not be considered Force Majeure. However, such
          inclement weather may provide the basis for a requested extension of
          schedule at the discretion of the Commonwealth without being
          considered Force Majeure.

     C.   If because of Force Majeure, either Party hereto is delayed in the
          performance of an obligation(s) under this Contract (other than the
          obligation of a party for monetary payment in connection with the
          performance of this Contract), and if such Party shall promptly
          deliver to the other Party written notice of such Force Majeure, then
          such obligation of the Party giving notice shall be suspended, as of
          the date of the notice, to the extent made necessary by Force Majeure
          and during its continuance. However, the Party giving notice shall use
          its best efforts to eliminate or overcome Force Majeure in order to
          minimize any delay in performance. The Party claiming Force Majeure
          shall use all reasonable efforts to mitigate the effects of Force
          Majeure upon the performance of the Contract.

     D.   Each party shall bear the costs it encounters as a result of the Force
          Majeure delay and the required efforts to mitigate the effects of the
          Force Majeure.

A.40 EXTENSION OF TIME DUE TO FORCE MAJEURE

     A.   After the beginning of any delay due to Force Majeure, Contractor
          shall promptly notify the Commonwealth verbally and in writing of the
          circumstances, and describe the action being taken to mitigate the
          effects of the delay.

     B.   Upon cessation of the Force Majeure, Contractor shall notify the
          Commonwealth in writing of the extension of time required, the
          Commonwealth shall then ascertain the facts, the effect on the
          Contract schedule(s), and make a good faith determination of the
          extension of time required, if any, and so notify Contractor in
          writing of the delay in the Contract schedule.

     C.   At a minimum, each day of Force Majeure delay should provide for an
          equivalent delay in the Contract schedule.

A.41 DAMAGES FOR DELAYS

     A.   Contractor shall receive no compensation for delays or hindrances to
          the work, except when direct and unavoidable extra cost to the
          Contractor is caused by the failure of the Commonwealth to provide
          information or material, if any, which is to be furnished by the
          Commonwealth and except as otherwise provided in this Contract.

     B.   When such extra compensation is claimed, the Contractor shall present
          a written claim to the Project Manager. Disapproval by the
          Commonwealth shall be subject to review


<PAGE>

          under Paragraph A.53, Dispute Resolution Process.

     C.   If delay is caused by specific orders given by the Project Manager to
          stop work, or by the performance of extra work, or by the failure of
          the Commonwealth to provide material or necessary instructions for
          carrying on the work, then such delay will entitle the Contractor to
          an equivalent extension of time, its applications for which shall,
          however, be subject to the approval of the Commonwealth; and no such
          extension of time shall release the Contractor or the surety on its
          performance bond from all of Contractor's obligations hereunder which
          shall remain in full force until the discharge of the Contract.

     D.   Contractor hereby covenants and agrees that each subcontract shall
          contain the following clause:

               "Except where the Contractor is found to be at fault or
          contributorily negligent, Contractor shall not be liable to a
          subcontractor for any delay to a subcontractor's work resulting from
          any act, negligence or default of the Commonwealth, or by reason of
          fire of other casualty, or on account of riots, strikes or other
          combined action of the workers or others, or on account of any acts of
          God or any other cause beyond Contractor's control; or on account of
          any circumstances caused or contributed to by a subcontractor."

A.42 BACKGROUND CHECKS

Contractor understands that its employees, agents, and subcontractors may have
access to sensitive or confidential information or materials under the control
of the Commonwealth during this Contract. Contractor agrees to require its
employees, agents, and subcontractors, and their employees, to agree to execute
signed individual releases authorizing the Commonwealth to conduct
investigations into those employees' backgrounds, criminal records, driving
records, and other desired measures as a condition of approval for assignment to
work on this Contract. Contractor further agrees that assignment of individuals,
agents, or subcontractors to work on this Contract shall be contingent upon
completion of such investigations with results to the satisfaction of the
Commonwealth.

A.43 INTOXICANTS AND DRUGS

     A.   Contractor shall not permit the introduction or use of intoxicating
          liquors or illegal drugs or any other drugs or substances which impair
          or may reasonably be expected to impair the performance or safety
          practices of any worker on the Site or on any of the grounds occupied
          or controlled by Contractor. Contractor shall not permit any worker or
          any other person on the Site who is or appears to be under the
          influence of any of the above stated substances.

     B.   If Contractor has an established drug screening program for its
          employees, Contractor shall apply such program to the work performed
          on the Site of the Contract.

A.44 PERFORMANCE BOND


<PAGE>

Contractor shall cause its surety to issue and maintain in favor of the
Commonwealth a performance bond in form and substance as set forth in Rider G.

A.45 PATENT, TRADEMARK, AND COPYRIGHT INFRINGEMENT INDEMNITY

     A.   WARRANTY. Contractor warrants that all goods, services, processes, and
          intellectual property furnished through, or used to perform this
          Contract will not infringe any patent, trademark, trade secret or
          copyright, provided that these items are not designed by the
          Commonwealth without Contractor's assistance. Contractor shall obtain
          all required licenses for the Commonwealth to use all software and
          hardware. If the use of any good, service, process or intellectual
          property furnished or used under this Contract is adjudged infringing
          and its use enjoined, Contractor shall, at its own expense, procure
          for use by the Commonwealth the right to continue using it, or replace
          it with a non-infringing equivalent, or modify it so that it becomes
          non-infringing. Contractor shall defend and reimburse the Commonwealth
          for any losses, costs and expenses including attorney's fees in
          connection with the enforcement of this warranty.

     B.   INDEMNITY. Contractor shall defend at its own expense any suits or
          proceedings brought against by the Commonwealth based on a patent,
          trademark or copyright infringement claim pertaining to any goods,
          services, processes, or intellectual property furnished or used by
          Contractor under this Contract. Upon receipt of a notice of a claim,
          the Commonwealth shall promptly notify Contractor of such a claim and
          provide assistance and information at Contractor's expenses. The
          Commonwealth has the right of participation in the suit or
          proceedings, if necessary. Contractor shall pay all judgments,
          damages, royalties and costs awarded against the Commonwealth and
          shall reimburse the Commonwealth therefor. This indemnity shall not
          apply to items designed by the Commonwealth without the Contractor's
          assistance.

A.46 REQUIRED INSURANCE COVERAGE

     A.   Contractor agrees to furnish certificates of insurance coverage issued
          by companies qualified to do business in the Commonwealth and in form
          acceptable to Commonwealth evidencing the following coverage and terms
          as hereinafter stated:

          i.   Worker's compensation insurance for all of the Contractor's
               employees and those of any subcontractor engaged in work at the
               Site of the project in accordance with the Worker's Compensation
               Act of 1915 and any supplements or amendments thereof.

          ii.  Public liability and property damage insurance to protect the
               Commonwealth, the Contractor, and any and all subcontractors from
               claims for damages for personal injury (including bodily injury),
               sickness or disease, accidental death, and damage to property,
               including loss of use resulting from any property damage, which
               may arise from operations under this Contract, whether such
               operation be by the Contractor or by anyone directly or
               indirectly employed by either. The limits of such insurance shall
               be in an amount not less than $5,000,000 each person and

<PAGE>

               $5,000,000 each occurrence, personal injury and property damage
               combined. Such policies shall be occurrence rather than claims
               made policies and shall name the Commonwealth as an additional
               insured.

          iii. The insurance shall also cover the following: Contractor's own
               trucks and automobiles, trucks and automobiles hired by the
               Contractor, trucks and automobiles not owned or hired by the
               Contractor but used in connection with this project. The
               Automobile Liability Policy shall cover the use of automobiles
               and trucks on and off the Site of this Contract.

          iv.  No policy of insurance provided hereunder shall contain any
               endorsements or any other form or clause designed to limit and
               restrict any action by the Commonwealth as an additional insured
               against the insurance coverage in regard to the work performed
               for the Commonwealth.

          v.   The deductible portion of each type of coverage shall not exceed
               five percent (5%) of the coverage limit.

     B.   Prior to commencement of work under the Contract, the Contractor shall
          provide the Office of Administration, Director, Radio Project Office,
          with current certificates of insurance as set forth above. These
          certificates shall contain a provision that coverage afforded under
          the policies will not be canceled or changed until at least thirty
          (30) days prior written notice has been given to the Office of
          Administration, Radio Project Office.

A.47 SUSPENSION

     A.   The Commonwealth shall have the right at any time to suspend all or
          any part of the work upon written notice to the Contractor.
          Thereafter, the Commonwealth shall pay to Contractor the difference
          between the value of the work performed, and the sum of the payments
          made prior to the date of suspension. This additional payment, if any,
          shall be credited to payments due following resumption of the work.
          Further payments in accordance with the terms of payment shall cease
          during the period of suspension, and Contractor shall be compensated
          for the delay and related damages incurred by it. When directed by the
          Commonwealth to resume the suspended work, Contractor and the
          Commonwealth shall establish a revised Project Schedule and revised
          deliverable dates.

     B.   The Contract price shall be adjusted to reflect any costs or savings
          attributable to such suspension of the work and extension of the
          schedule, and the adjustment to the Contract price shall be based upon
          the revised completion dates. Contract payments in accordance with
          terms of payment shall resume based upon the revised completion dates
          and revised Contract price.

     C.   If the work or any portion thereof has been suspended in accordance
          with the foregoing paragraph, and if the Commonwealth does not give
          notice in writing to Contractor to resume the work within thirty (30)
          days, then Contractor may declare the


<PAGE>

          suspended work or the suspended portion thereof as terminated for
          convenience, and then the termination charges as specified in
          Paragraph A.48 shall be based only on the portion of the work that is
          so terminated.

A.48 TERMINATION/CANCELLATION

     A.   The rights of termination and cancellation shall take precedence over
          the other provisions of the Contract.

     B.   The Commonwealth has the right to terminate this Contract for any of
          the following reasons:

          i.   TERMINATION FOR CONVENIENCE: The Commonwealth may terminate this
               Contract for its convenience if the Commonwealth determines
               termination to be in its best interest. The Contractor shall be
               paid for work satisfactorily completed prior to the effective
               date of the termination as well as for work in process and its
               costs of termination, but in no event shall the Contractor be
               entitled to recover loss of profits.

          ii.  NON-APPROPRIATION: Contractor understands that the Commonwealth's
               funds for this Contract are contingent on the availability of
               lawful appropriations by the Pennsylvania Legislature and
               authorization by the Governor. If the Pennsylvania Legislature or
               the Governor fails at any time to continue funding for the
               Contract, the Commonwealth's obligations under the Contract are
               terminated as of the date that the funding expires without
               further obligations of the Commonwealth. The Commonwealth
               represents that as at the date of this Contract sufficient funds
               have been appropriated for the full payment under this Contract.
               In the event this Contract is terminated pursuant to this
               Paragraph, the Commonwealth shall not procure the same or a
               similar statewide radio system for the remainder of the current
               fiscal year, unless less than 182 calendar days remain in the
               current fiscal year, in which case the Commonwealth shall not
               procure the same or similar statewide radio system until the end
               of the following fiscal year.

          iii. TERMINATION FOR CAUSE: Unless otherwise specified herein, the
               Commonwealth reserves the right to terminate this Contract upon
               written notice for Contractor's nonperformance or inadequate
               performance if Contractor fails to commence remedial actions to
               cure the same within thirty (30) days after receipt of written
               notice thereof.

     C.   Upon termination or cancellation for any reason, Contractor shall
          deliver to the Commonwealth at the Site, in good operating condition,
          and normal wear and tear excepted, materials or equipment supplied to
          Contractor by the Commonwealth.

A.49 PERFORMANCE GUARANTEES

During the period of this contract, Contractor guarantees that the performance
of the materials furnished under the Contract will meet the requirements of the
Contract relating to design and


<PAGE>

performance when operated in accordance with generally accepted operating
practices of public safety.

A.50 TAXES

     A.   The Commonwealth and the Contractor understand and agree that the
          Contractor will not be responsible for paying or collecting
          Pennsylvania sales and use tax, or any similar tax, levy, duty or
          charge ("Sales Tax"), with respect to any services or property,
          whether tangible or intangible, provided to the Commonwealth by the
          Contractor under this Contract. In particular, it is agreed and
          acknowledged that all tangible property to be transferred to the
          Commonwealth under this Contract will either retain its character as
          tangible personal property or will be considered building machinery
          and equipment for purposes of the Sales Tax. The Commonwealth shall
          provide such exemption certificates as may be required by the
          Contractor from time to time to substantiate or qualify for any
          applicable exemptions from the Sales Tax.

     B.   The amounts payable to the Contractor under this Contract have been
          determined based upon the assumption that no county, municipality,
          city, town or other political subdivision of the Commonwealth will
          impose a mercantile license tax, business privilege tax or any other
          local tax, duty, levy or similar charge ("Local Tax") on the
          Contractor with respect to this Contract or the Contractor's
          activities hereunder.

     C.   If and to the extent that a Sales Tax is imposed on any services or
          property transferred by the Contractor to the Commonwealth under this
          Contract, or that any Local Tax is imposed on the Contractor with
          respect to this Contract or the Contractor's activities hereunder, the
          Commonwealth shall reimburse the Contractor, as an additional payment
          under the Contract, the amount of any such Sales Tax or Local Tax.

     D.   The Commonwealth is exempt from all excise taxes imposed by the
          Internal Revenue Service and has accordingly registered with the
          Internal Revenue Service to make tax free purchases under Registration
          No. 2374001-K. With the exception of purchases of the following items,
          no exception certificates are required and none will be issued: undyed
          diesel fuel, tires, trucks, gas-guzzler emergency vehicles, and sports
          fishing equipment. The Commonwealth is also exempt from the
          Pennsylvania Sales Tax. The Sales and Use Tax Regulations provide that
          exemption certificates are not required for sales made to government
          entities and none will be issued. Nothing in this paragraph is meant
          to exempt a construction contractor from payment of sales tax or use
          tax required to be paid with respect to its purchase or use of
          tangible personal property used or transferred in connection with the
          performance of its construction contract.

A.51 WARRANTY

     A.   Contractor shall provide Factory Warranty on all items purchased via
          this Contract as specified in Rider F. Factory Warranty is included in
          the price of Equipment as listed in Rider C. This is Contractor's
          standard twelve (12) month "Return to Factory" commercial product
          warranty, covering repair or replacement only of defective


<PAGE>

          products, with the warranty period starting the date the product is
          shipped from the factory. The factory is defined as the Factory
          Staging Facility for the Commonwealth and as the point of manufacture
          for other purchasers (i.e., counties and municipalities).

     B.   Regional Warranty is a separately priced and optional service provided

          determined at selection of options as specified in Rider F. The
          Commonwealth must provide written notification of its intent to
          exercise either the two (2) year or five (5) year System Maintenance
          option at least sixty (60) days prior to the expiration of the two (2)
          year System Warranty.

          in the Proposal by making alternations or additions to or deletions
          from the work, without invalidating the Contract and without relieving
          or releasing Contractor from any responsibility or guarantee given by

          costs, and for anticipated profits or overhead on any portion of the
          Work that may be deleted by a change order. Agreed upon changes in the

          the change.

     D.   For any authorized change in the work, the contracting parties are
          restricted to the use of one of the following pricing methods to
          determine the amount to be added to or deducted from the Contract
          price for the change in work. The pricing method to be used shall be
          agreed upon and stated on the change order prior to Contractor's
          starting the change.

          i.   Method (1): By agreement upon unit prices, where applicable unit
               prices are not stipulated in the Contract, for the work to be
               done; or

          ii.  Method (2): By agreement upon a lump sum price for the work to be

               method is agreed upon, Contractor shall maintain accurate,
               current, itemized records for such time as the Commonwealth may
               require for a correct accounting of hours expended by labor
               category and the cost of materials, together with all proper
               vouchers and supporting documents.

     E.   If the change in work results in a credit to the Commonwealth from
          Contractor or from a subcontractor, the amount credited to the
          Commonwealth shall be the total actual


<PAGE>

          cost (as defined above) of the change in work.

     F.   An itemized statement of actual cost for changes increasing the work
          or for net credit to the Commonwealth for changes decreasing the work,

          Services. The information provided will be reviewed and if deemed to

          for contract awards.

          debarment by the Commonwealth, any other state, or the federal
          government, and if the Contractor cannot so certify, then it agrees to
          submit along with the bid/proposal, a written explanation of why such
          certification cannot be made.

          Contract any subcontractors/individuals who are currently suspended or
          debarred by the Commonwealth or federal government or who become
          suspended or debarred by the Commonwealth or federal government during
          the term of this Contract or any extensions or renewals thereof, the
          Commonwealth shall have the right to require the Contractor to
          terminate such subcontracts or employment.

          costs of investigation incurred by the Office of the Inspector General
          for investigations of the Contractor's compliance with the terms of
          this or any other agreement between the Contractor and the
          Commonwealth which results in the suspension or debarment of the
          Contractor. Such costs shall include, but not be limited to, salaries
          of investigators, including overtime; travel and lodging expenses; and
          expert witness and documentary fees. The Contractor shall not be
          responsible for investigative costs for investigations which do not

A.60 YEAR 2000 COMPLIANCE

The Contractor presents and warrants that each hardware, software and firmware
product delivered (or service performed) under the Contract, including

No hardware, software, firmware or service provided under the Contract shall
change the status of hardware, software and firmware product not supplied by
Contractor which is Year 2000 compliant from Year 2000 compliant to Year 2000
noncompliant. The Contractor must notify the Commonwealth of any Year 2000

delivered to the Commonwealth, by or though the Contractor, or any payment by
the Commonwealth to the Contractor under the Contract limit the effectiveness or
survival of this Year 2000 compliance representation and warranty.

contractor. No provision of this Contract will be interpreted to make the
parties to this Contract a partnership, principal-agent, employer-employee, or

No delay, waiver, omission, or forbearance on the part of the Commonwealth to

contained herein will constitute a waiver by the Commonwealth thereof to enforce
such right, option, or power as to any subsequent breach or default by
Contractor or a subcontractor.

A.63 PARTIAL INVALIDITY

Any provision of this Contract prohibited by law or by court decree in any
locality or state shall be suspended to the extent of such prohibition without

of warranty or contract, tort (including negligence) or otherwise, exceed an
amount equal to the aggregate value of RPRs issued under this Contract at the
time the Commonwealth first became aware of the occurrence of the event
allegedly giving rise to such liability. Such amount shall be reduced by any
monies paid to the Commonwealth pursuant to the Liquidated Damages clause to the
extent that such liability is attributable to Contractor caused delays. Any work
or services provided by the Performance Bond shall be taken into consideration
as mitigating any damage to the Commonwealth. In no event shall Contractor of

of $500,000 for consequential, indirect, incidental, or special damages

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

B-2.1.3 REQUEST FOR DESIGN (RFD) - SITE

The Request for Design is a written notification to the Contractor from the
Commonwealth that the Contractor shall proceed with generation of a preliminary
site development design for consideration by the Commonwealth. The RFD will be
accompanied by a Site Information Package, in which the Commonwealth will
provide the Contractor with specific site details to the extent it is available.
Any information not available at the time the RFD is released, will be provided
to the Contractor during the initial site visit or upon approval of the
Preliminary Site Plan. Site Information Packages will be provided for either new
sites or existing sites that may require site development modification.

The Site Information Package (SIP) will consist of the site description
including: site location, latitude and longitude data, site elevation, legal
description, and travel directions; site access information including:
identification of any locked gates and key locations, land/site owner to include
a point of contact and telephone number, site use agreement, or authorization as
applicable. The SIP will also provide (if available) any known easements, zoning
or permit issues; access road, compound information, and existing utility
locations. Also included will be planned or existing: tower type, height,
lighting requirements, and ice bridges; shelter size and orientation, generator
size and positioning, fuel tank size and positioning, and existing or planned
foundation type and location. The Site Information Package will also provide
approximate tower and shelter loading to the extent that the appropriate tower,
shelter, and power/generator templates can be incorporated into the Preliminary
Site Plan. Inclusion or omission of any of the above data in the SIP, by the
Commonwealth does not relieve the Contractor of their responsibilities to gather
Site Planning and Design data as described in the RFP, the Proposal or the
Contract.

B-2.1.4 REQUEST FOR DESIGN (RFD) - REGION

The Request for Design - Region is a written notification from the Commonwealth
to the Contractor to proceed with generation of a regional development design,

B-5      TOWERS

The tower system is intended to support the two-way voice, data, and microwave
communications equipment for the Commonwealth of Pennsylvania Statewide Radio
System. The Commonwealth shall define the actual types, heights and locations
based upon the final radio and microwave system designs.

The Commonwealth has developed requirements for towers and has composed a set of
specifications. The RFP defines basic and optional requirements to support the
system implementation of the microwave and radio subsystems. The following
defines these requirements and tasks as provided in the RFP.

TOWER DESIGN

All towers will have basic requirements. These basic requirements are the same
for all towers. An example of a basic requirement is wind loading of 80 mph with
concurrent 1/2-inch radial ice (non-derated). The performance of this
requirement is independent of the size of the tower, material type, or the
foundation design.

In addition to basic requirements, there will also be variable requirements. As
tower sizes increase these variable requirements may require more material,
increase in capacity, or replace a specific item to provide required
performance. An example of a variable requirement is the use of different tower
members to support different antenna loads. The tower members need to be
stronger in order to support greater antenna loads.

There will also be variable features that can be applied to any tower as
required on a site by site basis. These variable features shall be in addition
to the basic requirements of any tower. In some specific circumstances, an
optional feature may altogether replace a basic requirement. This is noted in
the RFP. An example of a variable feature is the type of tower lighting. Some

F-1.1    DEGREES OF FAILURE ON INFRASTRUCTURE EQUIPMENT

The following defines two categories of failure. Major and Minor failures shall
have different response and restoration times as described below.

F-1.1.1       MAJOR FAILURE

Any failure that results in a loss of voice or data service, a complete
outage or reduction of System capacity, that are not restored by hot standby or
fault tolerant Equipment, shall constitute a major failure. All major failures
require immediate service as stipulated by the response and repair times
associated with the various Equipment types outlined in this document.

F-1.1.2       MINOR FAILURE

Any failure that generates a concern or alarm of any nature other
than major, as defined above, shall be deemed a minor failure. All minor
failures must be cleared during the course of the normal workday on which they
occur. In the event a minor failure occurs after hours, on a weekend or holiday,
as defined in Rider B, shall be repaired during the next normal working day.

F-1.2    MALFUNCTIONED EQUIPMENT

Malfunctions that cannot be immediately or unequivocally diagnosed and
pinpointed to a certain item of Equipment or service shall require the
participation of all service suppliers until responsibility for the problem
has been established. In no instance shall the failure to resolve the issue
of responsibility relieve any of the suppliers of the mutual obligation to
restore System operability with the least impact on the availability of the
System to the end users.

F-1.3    PREVENTATIVE MAINTENANCE

Contractor shall provide preventative maintenance on all Equipment as specified
in order to be compliant with the response times as indicated in this rider. In
addition Rider B (Statement of Work) shall further define the Preventive

All test equipment utilized for installation, warranty and
maintenance on the Statewide-Integrated Voice and Data System shall be
calibrated as recommended by the Equipment manufacture(s) and traceable to the
National Bureau of Standards. The Contractor Program Manager must maintain
certificates of calibration.

F-2      STANDARD WARRANTY TERMS

Warranty shall be defined as the standard Contractor Warranty Terms, as
indicated below.

                         CONTRACTOR'S STANDARD WARRANTY

Contractor warrants for a period of twenty-four (24) months from the date of
completion and acceptance of a site commodity that the Equipment will be free
from defects in material and workmanship and will be in conformity with
applicable specifications and drawings (the "Specifications"); provided,
however, that this warranty shall not apply to any Equipment which shall have
been abused or misused physically or electrically, or on which the trademark
shall have been defaced or obliterated. Buyer shall request written return
material authorization within the warranty period prior to the return of any
nonconforming Equipment. If Equipment is found not in conformance with this
warranty, it will be covered by this warranty only if written authorization is
requested within a period of twenty-four (24) months from the date of
commencement.

Authorization for return must be secured from Contractor and will not commit
Contractor to the making of any repair or replacement hereunder. Requests for
return authorization should list types and quantities of Equipment involved, the
reason for the request, information concerning operating conditions involved,
and the period of use. In addition, the Order number and, where possible, the
original invoice number covering the original purchase of the Equipment involved
must be shown. Returned Equipment must be shipped, and transportation prepaid,
by the most practical method of shipment. Shipping costs will be credited to the
Buyer for all Equipment found to be not in compliance with this warranty.
Excessive transportation costs will not be allowed. Contractor can accept no
billing for packing, inspection, labor charges or other incidental costs in
connection with any Equipment returned. Unless otherwise requested by Buyer,
returned Equipment found not subject to this warranty will be sent back to
Buyer, transportation collect. In all cases, Contractor's determination will be
final. With respect to Equipment found not in conformity with this warranty, the
remedy will take the form, at Contractor's option, of a replacement or repair of
the defective or nonconforming Equipment.

In the event that it is uneconomical to replace or repair warranted Equipment,
Contractor may, at its sole option, remit the dollar equivalent based upon the
original Equipment sales price and said remittance will be calculated by
applying the pro rata percentage of the unexpired warranty to the original
Equipment sales price. Seller makes no representation or warranty, express,
implied (including but not limited to warranties of merchantability and fitness
for particular purposes), statutory, or related to "Year 2000" matters, other
than the foregoing express warranty. THIS WARRANTY IS IN LIEU OF ALL OTHER
WARRANTIES WHETHER WRITTEN, ORAL, EXPRESS OR IMPLIED (INCLUDING, WITHOUT
LIMITING THE GENERALITY OF THE FOREGOING, ANY WARRANTY OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE). IN NO EVENT WILL CONTRACTOR BE

      CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR" PROVISIONS OF
                   THE PRIVATE SECURITIES REFORM ACT OF 1995

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

         We caution readers that the important factors set forth below, as well
as factors discussed in other documents filed by us with the Securities and
Exchange Commission, among others, could cause our actual results to differ
materially from statements contained in this report, our future filings with the
Securities and Exchange Commission, our press releases and oral statements made
by or on behalf of our Company. Forward-looking statements are not guarantees of
future performance and are subject to risks, uncertainties and other factors
(many of which are beyond our control) that could cause actual results to differ
materially from future results expressed or implied by such forward-looking
statements. The word "estimate", "project", "anticipate", "expect", "intend",
"believe", "target", and similar expressions are intended to identify
forward-looking statements. Among these statements are those concerning

         -        Our anticipated growth and business strategies

         -        Our expected growth in international markets

         -        Our ability to expand into new markets such as HDTV towers

         -        Anticipated trends and conditions in the telecommunications
                  industry

         -        Our future capital needs

         -        Our ability to compete, on time and on budget, large scale
                  projects, such as our Level III and State of Pennsylvania
                  projects, where the Company acts as a project Manager, as well
                  as a manufacturer.

         -        Our continued ability to decrease costs and maintain or
                  increase our margins

         -        Our ability to compete

         The forward-looking statements regarding such matters are based certain
assumptions and analyses made by us in light of our management's experience and
its perception of historical trends, current conditions, and expected future
developments, as well as other factors it believes are appropriate in the
circumstances.

         Important factors that could cause actual results to differ materially
from those implicit in our forward-looking statements include, without
limitation:

         (1)      the price and quality of similar or comparable communications
                  infrastructure equipment offered or to be offered by our
                  competitors; increased price-based competition could have a
                  significant impact on our margins;

         (2)      decreases in demand of, or continued softness levels of demand
                  for, our tower and enclosure products;

         (3)      fluctuations in demand for our products resulting in
                  inefficient labor force utilization;

         (4)      difficulties in obtaining or retaining management or other
                  human resource competencies we need to achieve our business
                  objectives;

         (5)      failure to penetrate new markets, especially in Latin
                  America;

         (6)      general economic conditions in the United States and Latin
                  America;

         (7)      increases in domestic or international interest rates;

         (8)      the price and availability of certain raw materials used in
                  our production processes; and

         (9)      future domestic or international legislation or regulatory
                  actions relating to wireless communications services or
                  telecommunications generally.
