             CAUTIONARY STATEMENT REGARDING RISKS AND UNCERTAINTIES
                   RELATING TO OUR FORWARD-LOOKING STATEMENTS

     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 words
"estimate", "project", "anticipate", "expect", "intend", "believe", "target",
"potential", "outlook" and similar expressions are intended to identify
forward-looking statements. Among these statements are those concerning

-    Our revenues, earnings and earnings per share for the year 2001 and
     subsequent periods,
-    Our liquidity and the sufficiency of our working capital and other sources
     of liquidity for the conduct of our business,
-    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 and plans for capital expenditures,
-    Our ability to complete, on time and on budget, large scale projects, such
     as our Commonwealth of Pennsylvania project, where we act as a project
     manager, as well as a manufacturer,
-    Our continued ability to decrease costs and maintain or increase our
     margins, and
-    Our ability to compete.

     Our forward-looking statements regarding these and other matters are based
on 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,
those discussed below.

     WE DEPEND ON THE CONTINUED GROWTH IN DEMAND FOR WIRELESS AND FIBER OPTIC
COMMUNICATIONS SERVICES AND THE CONTINUED ACCESS OF OUR DIRECT AND INDIRECT
CUSTOMERS TO CAPITAL IN ORDER TO FUND EXPANSION. DECREASES IN THE GROWTH RATES
FOR CONSUMPTION OF WIRELESS OR FIBER OPTIC COMMUNICATIONS SERVICES, THE BUILD
OUT OR UPGRADING OF NETWORKS TO PROVIDE THOSE SERVICES, OR THE INABILITY FOR
COMMUNICATIONS SERVICE PROVIDERS TO RAISE CAPITAL, COULD REDUCE DEMAND FOR OUR
PRODUCTS AND ADVERSELY IMPACT OUR REVENUES AND OPERATING RESULTS.

     Achievement of our business objectives depends on the continued growth of
the wireless and fiber optic communications industries. If these industries do
not continue to grow, the demand for our products and services may not continue
to develop.

<PAGE>

     While the wireless and fiber optic communication service industries have
made substantial investments in the build out of communications infrastructure
since 1999, more recently companies in this sector have found it more difficult
to raise capital. This difficulty, if continued, will impede the continued
growth and upgrading of wireless and fiber optic communications infrastructure
and could reduce demand for our products.

     MANY OF OUR CUSTOMERS MAY TERMINATE CONTRACTS WITH MINIMAL OR NO PENALTY
BEFORE COMPLETION, OR DELAY DELIVERY OF PREVIOUSLY PLACED ORDERS; THIS COULD
ADVERSELY AFFECT OUR BACKLOG (OR "BOOKINGS"), REVENUES AND EARNINGS.

     Most of the agreements we have with our customers, including contracts we
include in our backlog, allow those customers to terminate their contracts with
little or no penalty or require delivery of a purchase order or similar
authorization in order for us to produce and complete delivery of the relevant
product or service. As a result, often the customer maintains the ability to
cancel or delay, indefinitely or significantly, the delivery of products or
services. When a customer cancels an order or withdraws a firm delivery date,
that order is removed from our backlog. The exercise by a significant portion of
our customers of these termination or deferral rights could adversely affect our
backlog, revenues and earnings.

     OUR INDUSTRY IS HIGHLY COMPETITIVE. COMPETITIVE PRESSURES HAVE IN THE PAST,
AND COULD AGAIN IN THE FUTURE, ADVERSELY AFFECT OUR REVENUES AND OPERATING
MARGINS.

     The telecommunications infrastructure industry is highly competitive. We
face substantial competition in the Tower Structures, Equipment Enclosures and
Construction Services segments of our business from established competitors,
some of which have greater financial, engineering, manufacturing, and marketing
resources than us. Our 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 our operating margins in 1998 and early 1999,
ADVERSELY AFFECTING OUR EARNINGS. IN THE FUTURE, PARTICULARLY IN THE EVENT OF
SOFTENING DEMAND FOR OUR products, competitive pressures could necessitate price
reductions, adversely affecting operating results.

     OUR INDEBTEDNESS COULD RESTRICT OUR OPERATIONS, MAKE US MORE VULNERABLE TO
ADVERSE ECONOMIC CONDITIONS AND MAKE IT MORE DIFFICULT FOR US TO IMPLEMENT OUR
BUSINESS STRATEGY AND ACHIEVE THE OBJECTIVES OF THAT STRATEGY.

     Assuming the successful completion of our March 2001 self tender offer, and
the related purchase of common stock from our largest stockholder, we will have
a significant amount of indebtedness, particularly as compared to the net cash
position we operated with prior to entering into credit facilities related to
the tender offer.

     Our current and future indebtedness could have important consequences to
us. For example, it could:
-    impair our ability to obtain additional financing for working capital,
     capital expenditures, acquisitions or general corporate or other purposes
-    limit our ability to use operating cash flow in other areas of our business
     because we must dedicate a substantial portion of these funds to make
     principal and interest payments on our indebtedness
-    put us at a competitive disadvantage to less leveraged competitors
-    hinder our ability to adjust rapidly to changing market conditions
-    increase our vulnerability in the event of a business or general economic
     downturn
-    increase our vulnerability to interest rate increases to the extent our
     variable-rate debt is not effectively hedged, and
-    limit, along with the financial and other restrictive covenants in our
     indebtedness, our ability to make investments or take other actions or
     borrow additional funds.

     Our ability to repay or refinance our indebtedness will depend on our
financial and operating performance, which, in turn, is subject to prevailing
economic and competitive conditions and to financial, business and other
factors, many of which are beyond our control. These factors could include
operating

<PAGE>

difficulties, increased operating costs or raw material prices, the response of
competitors, regulatory developments and delays in implementing strategic
projects. Our ability to meet our debt service and other obligations may depend
in significant part on the extent to which we can successfully implement our
business strategy. We may not be able to implement our business strategy or the
anticipated results of our strategy may not be realized.

     IF, IN THE FUTURE, WE CANNOT GENERATE ENOUGH CASH FROM OPERATIONS TO MAKE
SCHEDULED PAYMENTS ON our indebtedness, we may be required to reduce or delay
capital expenditures, refinance our indebtedness, obtain additional financing or
sell assets. Our business may not be able to generate sufficient cash flow, and
we may not be able to obtain funding sufficient or utilize other means to
satisfy our debt service requirements.

     THE OPERATING AND FINANCIAL RESTRICTIONS IMPOSED BY OUR CREDIT FACILITY
COULD NEGATIVELY AFFECT OUR ABILITY TO FINANCE OPERATIONS AND CAPITAL NEEDS OR
TO ENGAGE IN OTHER BUSINESS ACTIVITIES.

     Our credit facility will contain covenants that limit our ability and our
subsidiaries' ability to:

-    incur additional indebtedness
-    incur liens on property or assets
-    make acquisitions
-    merge or consolidate with third parties
-    make restricted payments and investments
-    pay dividends and make distributions
-    repurchase or redeem capital stock
-    dispose of assets
-    guarantee obligations
-    enter into sale and leaseback transactions, and
-    engage in certain transactions with subsidiaries and affiliates and
     otherwise restrict corporate activities.

     In addition, our credit facility contains financial covenants, including:

-    a maximum ratio of total debt to EBITDA
-    a minimum fixed charge coverage ratio
-    a maximum ratio of book value to our non-guarantor subsidiaries to our
     consolidated book value
-    a minimum EBITDA test, and
-    a minimum net worth test.

     OUR ABILITY TO MEET THESE COVENANTS AND REQUIREMENTS IN THE FUTURE MAY BE
AFFECTED BY EVENTS BEYOND our control, including prevailing economic, financial
and industry conditions. Our breach or failure to comply with any of these
covenants could result in a default under our credit facility. If we default
under our credit facility, the lenders could cease to make further extensions of
credit, cause all of our outstanding debt obligations under our credit facility
to become due and payable, require us to apply all of our available cash to
repay the indebtedness under our credit facility or prevent us from making debt
service payments on any other indebtedness we owe. If the indebtedness under our
credit facility or the notes is accelerated, we may not have sufficient assets
to repay amounts due under our credit facility or other debt agreements then
outstanding.

     OUR BUSINESS PLAN CALLS FOR THE EXPANSION OF OUR CASA GRANDE , ARIZONA
ENCLOSURE FACILITY AND THE START-UP OF OUR PEORIA, ILLINOIS POLE FACILITY. IF WE
ARE UNABLE TO INITIATE PRODUCTION OR ACHIEVE EXPECTED COST LEVELS ON OUR
ANTICIPATED SCHEDULE, OUR REVENUE AND OPERATING MARGINS COULD BE ADVERSELY
AFFECTED.

     During 2001, we expect to complete an expansion of our Casa Grande, Arizona
enclosure facility and construct and start-up a new pole facility at our Peoria,
Illinois location. While we expect to experience

<PAGE>

increased costs in connection with the start-up of these facilities, we also
expect these costs to decrease as we and our employees gain more experience.
Delays in the expansion of our Casa Grande, Arizona facility or the start-up of
the our Peoria, Illinois facility or in achieving the anticipated cost
reductions could adversely affect our revenues and operating margins.

     WE MAY BE UNABLE TO IMPLEMENT SUCCESSFULLY OUR GROWTH OBJECTIVES IN
INTERNATIONAL MARKETS.

     Our business strategy includes increasing our international sales through
increased sales and marketing activities in targeted regions, by entering into
strategic alliances, joint ventures and/or other business arrangements. Our
efforts to increase international sales may be adversely affected by, among
other things:

-    changes in foreign import restrictions and regulations,
-    taxes,
-    currency exchange rates,
-    currency and monetary transfer restrictions and regulations,
-    changes in U.S. law affecting foreign trade, and
-    economic and political changes in the foreign nations in which our products
     are sold.

     One or more of these factors could have a material adverse effect on our
business, financial condition or results of operations in the future.

     In addition, our international business strategy may require us to make
significant investments outside of the United States. While our credit agreement
permits international investments, subject to specified limits, we can not be
certain that the permitted amount will be sufficient to fully execute our
international business strategy.

     OUR CONSTRUCTION BUSINESS'S SUCCESS REQUIRES THAT WE COMPLETE THE PROJECTS
WE MANAGE ON TIME AND ON BUDGET. OUR ABILITY TO DO THIS CAN BE ADVERSELY
AFFECTED BY VARIOUS FACTORS, MANY OF WHICH ARE BEYOND OUR CONTROL, INCLUDING THE
FAILURE OF SUB-CONTRACTORS TO PERFORM THEIR SERVICES, THE INABILITY OF CUSTOMERS
TO OBTAIN NECESSARY PERMITS AND OTHER AUTHORIZATIONS ON SCHEDULE, AND INCLEMENT
WEATHER.

     Our construction business typically manages projects for which a fixed
price has been provided to the customer. As a result, the success of that
business depends on our ability to complete these projects in accordance with
the schedules and budgets on which we based the pricing of the projects. Our
ability to meet this objective is subject to various risks including:

-    the failure of subcontractors and other third parties who perform services
     in connection with our construction projects to perform their services in a
     satisfactory and timely manner, or the inability of our customers, who
     typically are responsible for obtaining the necessary permits and
     authorizations for tower construction, to obtain those permits and
     authorizations on a basis that allows the project to be constructed on the
     anticipated schedule; and
-    delays caused by unusual or inclement weather.

     INCREASES IN RAW MATERIAL COSTS COULD ADVERSELY IMPACT OUR GROSS PROFIT
MARGINS.

     Steel, zinc and concrete constitute a significant portion of our costs of
goods sold. In the event of an increase in our costs for these products, we may
not be able to pass on the increased cost by raising the prices of our products,
which could have a material and adverse impact on our gross profit margins.

     WE ARE DEPENDENT ON OUR SENIOR MANAGEMENT. IF WE LOSE MEMBERS OF OUR SENIOR
MANAGEMENT, WE MAY NOT BE ABLE TO FIND APPROPRIATE REPLACEMENTS ON A TIMELY
BASIS AND OUR BUSINESS COULD BE ADVERSELY AFFECTED.
<PAGE>

     Our existing operations and continued future development depend to a
significant extent upon the performance and active participation of certain key
individuals as employees. We cannot guarantee that we will be successful in
retaining the services of these, or other key personnel. If we were to lose any
of these individuals, we may not be able to find appropriate replacements on a
timely basis and our financial condition and results of operations could be
materially adversely affected.

     RISKS ASSOCIATED WITH THE OPERATION OF OUR MANUFACTURING FACILITIES MAY
HAVE A MATERIAL ADVERSE AFFECT ON OUR BUSINESS.

     Our revenues are dependent on the continued operation of our various
manufacturing facilities. The operation of manufacturing plants involves many
risks including

-    the breakdown, failure or substandard performance of equipment,
-    inclement weather and natural disasters,
-    THE NEED TO COMPLY WITH DIRECTIVES OF, AND MAINTAIN ALL NECESSARY PERMITS
     FROM, GOVERNMENT AGENCIES,
-    raw material supply disruptions,
-    labor force shortages, work stoppages or other labor difficulties, and
-    transportation interruptions.

     The occurrences of material operational problems, including but not limited
to the above events, may have a material adverse effect on the productivity and
profitability of a particular manufacturing facility, or with respect to various
facilities of our company as a whole, during the period of the operational
difficulties.

     FUTURE DOMESTIC OR INTERNATIONAL LEGISLATION OR REGULATORY ACTIONS RELATING
TO WIRELESS COMMUNICATIONS SERVICES OR TELECOMMUNICATIONS COULD NEGATIVELY
IMPACT TOWER SALES.

     Concern over tower proliferation has grown in recent years, and as a result
certain communities have placed restrictions on new tower construction or have
delayed granting permits required for construction. These concerns could result
in our customers not being able to place all of the towers currently
anticipated.

     We do not undertake any obligation to release publicly any revisions to our
forward-looking statements to reflect events or circumstances after the release
of such statements or to reflect the occurrence of unanticipated events.
