     The following summary is qualified in its entirety by the more detailed
information and financial statements and notes thereto contained elsewhere in
this Prospectus. Unless otherwise indicated, the information in this Prospectus
assumes the Underwriters' over-allotment option is not exercised and gives
retroactive effect to a   -for-1 stock dividend effected in             , 1998.
All references to fiscal years, unless otherwise noted, refer to the Company's
fiscal year which ends on April 30 of each year. The Company was incorporated in
Texas in 1983 under the name "Page-Com, Inc." ("Page-Com") and was thereafter
renamed "Wireless International, Inc." In December 1995, a subsidiary of the
Company merged (the "Merger") with Bear Communications, Inc. ("Bear
Communications"). Unless the context otherwise requires, all references to
"BearCom" shall include the operations of the Company's direct and indirect
wholly owned subsidiaries, Bear Communications, BearCom Operating, L.P. and
their subsidiaries. On March 31, 1998, a wholly owned subsidiary of the Company,
Condor Holdings, Inc. ("Condor Holdings"), acquired substantially all of the
assets of Condor Communications, Inc. ("Condor Communications," and together
with Condor Holdings, "Condor"). The foregoing transaction is referred to herein
as the "Condor Acquisition." Unless the context otherwise requires, all
references to "Condor" shall include Condor and Condor's fifty percent interest
in Condor Telecommunicationes, C.A., a corporation incorporated under the laws
of Venezuela, which operates Condor's Caracas, Venezuela distribution sales
office. As of the date hereof, the Company is awaiting regulatory approval in
the Czech Republic with respect to the acquisition of the entity that operates
Condor's Prague, Czech Republic distribution sales office. Based on the advice
of foreign counsel, the Company believes regulatory approval will be obtained.
All references herein to "Wireless International" or the "Company" shall include
the combined operations of Wireless International, Inc. and its subsidiaries,
including BearCom and Condor.
 
                                  THE COMPANY
 
     The Company is the largest independent distributor of two-way radios in the
world with leading positions in the field sales, catalog sales, export sales and
rental segments of the market. The Company sells, services and rents a broad
line of two-way radios manufactured by industry leaders including Motorola,
Maxon, Icom and Tekk, which are used to communicate within a limited geographic
area without incurring airtime or subscriber charges. In the United States, the
Company's diverse customer base consists primarily of businesses and
organizations across a wide variety of industries, whereas internationally the
Company's customers generally are dealers which, in turn, sell to similar end
users. In addition to its two-way radio product line, the Company sells
complementary wireless communication and related products and services,
including Orbacom console systems, Motorola messaging systems, Nextel handsets
and services and PageMart pagers and services.
 
     Through BearCom, the Company markets its products and services through 34
field offices in the United States and two in Australia and through its catalog
operations throughout the United States. In addition, through Condor, the
Company exports its products and services through its distribution offices in
Miami, Florida, Caracas, Venezuela and Prague, Czech Republic. The Company
believes that it is the only significant distributor of two-way radios
leveraging the strengths of these multiple channels of distribution. Through its
field offices, BearCom provides technical assistance for customers requiring
on-site evaluation of their communications needs. For customers not requiring
this consultative approach (usually when system needs are relatively
uncomplicated or purchases are add-on or replacement units to an existing
system), the catalog marketing channel provides an efficient and convenient
method of purchasing products. During fiscal 1997, BearCom mailed more than 4.4
million catalogs and marketing pieces and processed in excess of 150,000
customer orders. Most orders are processed and shipped on the same day they are
received. The Company uses sophisticated information systems and proprietary
software to monitor and refine its customer database, catalog mailings and
inventory levels. In addition, the Company has a fleet of over 15,000 two-way
radios for rent, which are used in connection with sporting events, conventions,
disaster recovery projects, motion picture productions and other events. The
Company believes that it is the largest renter of two-way radios in the United
States.
 
                                        3
<PAGE>   5
 
     While the Company is not aware of any definitive industry data, the Company
believes that the market for the sale, rental and service of two-way radios and
related products is in excess of $5 billion per year in the United States and an
additional $5 billion per year outside the United States. The independent
distribution of two-way radios is a highly fragmented industry, with thousands
of local and regional independent dealers. The manufacturing of two-way radios,
however, is dominated by a small number of companies, each of which has
developed a network of authorized dealers to augment their internal direct sales
forces. These authorized dealer networks typically comprise several local
dealerships within a given metropolitan area each generating less than $5
million in sales. Over the past ten years, manufacturers have strategically
reduced the size of their direct sales forces, increasingly relying on
independent authorized dealers. The Company believes that an increasing
percentage of two-way radio products will continue to be sold through
independent dealers as manufacturers continue to outsource distribution and
other non-core functions. At the same time, the Company believes manufacturers
are limiting their authorized dealer relationships to fewer, but larger
organizations. The Company believes that these industry fundamentals and
outsourcing trends will lead to a consolidation of independent dealers and that
as the largest independent dealer worldwide it is well positioned to continue to
acquire local authorized dealers and expand its international presence and
market share.
 
     From fiscal 1993 to fiscal 1997, the Company's revenues grew, primarily as
a result of internal growth and the opening of nine new sales offices, from
$37.9 million to $69.6 million, representing a compound annual growth rate of
approximately 16%. Since August 1996, the Company has accelerated its growth
through the acquisition of the operations of 12 independent dealers, a majority
of the assets of Motorola's Radio Products Group rentals business and
substantially all of the assets of Condor. As a result, revenues for the nine
months ended January 31, 1998 were $67.1 million, a 31% increase from revenues
generated during the equivalent period of the prior fiscal year. On a pro forma
basis, giving effect to the Condor Acquisition and the Other Acquisitions (as
defined below under "Unaudited Pro Forma Condensed Consolidated Financial
Statements"), the Company's revenues were $131.4 million and $112.7 million
during fiscal 1997 and the nine months ended January 31, 1998, respectively. The
Company intends to make additional acquisitions to establish a presence in new
geographic areas and to enhance its presence in existing markets. In pursuing
such acquisitions, the Company typically seeks to gain access to the acquired
dealer's skills, experience and customer relationships, while consolidating its
fulfillment operations into existing facilities.
 
     The Company's objective is to expand its position as the largest
independent distributor of two-way radios and related products in the world and
be the leading independent distributor in each market in which it serves. The
Company's strategy is to further develop its network of field offices by opening
and acquiring local operations, expand and enhance its catalog and export
operations, leverage its complementary distribution channels by expanding its
product and service offerings, and support such operations with rapid order
fulfillment and superior customer service and technical support. The Company
seeks to capitalize on its experience and reputation derived from more than 15
years of selling and marketing two-way radio products in executing its strategy
and addressing its market opportunity.
 
                              RECENT DEVELOPMENTS
 
     On March 31, 1998, the Company completed the Condor Acquisition. Condor
reported revenues of $51.4 million during its fiscal year ended December 31,
1997. The Condor Acquisition was accounted for using the purchase method of
accounting.
 
     Based in Miami, Florida, Condor is a leading exporter of two-way radio
communication equipment and communication systems primarily to Latin America,
Eastern Europe, Africa and the Middle East. In addition to its Miami office,
Condor maintains distribution sales offices in Caracas, Venezuela and Prague,
Czech Republic. Condor exports primarily Motorola two-way radio products.
Virtually all of Condor's sales are denominated in U.S. dollars. The Condor
Acquisition provides the Company an operational platform from which it can
expand its international operations. The Company's strategy is to expand its
international operations by establishing additional sales offices within
licensed regions and offering additional products and services within those
regions. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Condor Communications, Inc.," "Unaudited Pro Forma
Condensed Consolidated Financial Statements" and the historical consolidated
financial statements of Condor included elsewhere herein.

                                  RISK FACTORS
 
     This Prospectus contains forward looking statements. The words
"anticipate," "believe," "expect," "plan," "intend," "estimate," "project,"
"will," "could," "may" and similar expressions are intended to identify forward
looking statements. Such statements reflect the Company's current views with
respect to future events and financial performance and involve risks and
uncertainties, including, without limitation, the risks described in this
section. Should one or more of these risks or uncertainties occur, or should
underlying assumptions prove incorrect, actual results may vary materially and
adversely from those anticipated, believed, expected, planned, intended,
estimated, projected or otherwise indicated. In addition to the other
information contained in this Prospectus, prospective investors should carefully
consider the following risk factors before making an investment in the Common
Stock offered hereby.
 
NO ASSURANCE OF GROWTH
 
     In recent years, the Company has rapidly expanded its operations, growing
from total revenues of $37.9 million in fiscal 1993 to $69.6 million in fiscal
1997. The Company plans to seek continued growth of its business by increasing
sales in its existing offices and catalog operations, through strategic
acquisitions and by opening new offices. There can be no assurance, however,
that the Company will continue to grow or will be able to successfully implement
any of these growth strategies.
 
     To successfully implement its growth strategies, the Company must
continually evaluate the adequacy of its existing systems and procedures,
including, among others, its data processing, financial and internal control
systems and management structure. There can be no assurance that the Company
will adequately anticipate all of the changing demands that growth will impose
on the Company's systems, procedures and structure. Any failure to adequately
anticipate and respond to such changing demands is likely to have a material
adverse effect on the Company. In addition, the Company anticipates that
acquiring or opening offices will involve a number of possible risks and
challenges, including the diffusion of managements attention, the dependence on
hiring, training and retaining key personnel, and unanticipated problems or
liabilities, some or all of which could have a material adverse effect on the
Company. See "Business -- Growth Strategy."
 
ACQUISITION RISKS; BUSINESS INTEGRATION RISKS
 
     Since August 1996, the Company has acquired the stock or assets of 12
independent dealers of two-way radios and other wireless communication products,
a majority of the assets of Motorola's Radio Products Group rentals business and
substantially all of the assets of Condor Communications, Inc. The Company
intends to seek continued growth of its business through future strategic
acquisitions. The Company is currently evaluating certain strategic
acquisitions; however, the Company has no binding commitment to acquire any
business or other material assets. There can be no assurance that the Company
will be able to identify future attractive acquisition candidates or complete
the acquisition of any candidates on terms favorable to the Company. Growth
through strategic acquisitions involves numerous risks, including difficulties
in the integration of the operations, systems and personnel, including key
management, of acquired businesses and the diversion of management's attention
from other business concerns. In the event that the Company acquires businesses,
the employees of which are parties to collective bargaining agreements, the
Company would be subject to risks inherent in such arrangements, including
strikes or work stoppages. There can be no assurance that any acquired
businesses, including Condor, can be successfully integrated into the Company's
business. A substantial portion of the Company's capital resources, including a
portion of the proceeds of the Offering, could be used for acquisitions. The
Company may require additional debt or equity financing for future acquisitions,
which additional financing may not be available on terms favorable to the
Company, if at all. See "Business -- Growth Strategy."
 
DEPENDENCE ON VENDOR
 
     The sale of products by BearCom that were purchased from the Company's
largest vendor, Motorola, Inc. ("Motorola"), constituted approximately 73% of
the Company's equipment revenues during fiscal 1997 and approximately 67% of the
Company's equipment revenues during the nine-month period ended
 
                                        7
<PAGE>   9
 
January 31, 1998. In addition, BearCom's rental radio inventory consists
primarily of products manufactured by Motorola and a very high percentage of
Condor's equipment revenues were generated by the sale of products purchased
from Motorola. As is customary in the industry, the Company does not have
long-term contracts with any of its vendors, including Motorola. Although the
Company and its suppliers enter into written vendor agreements to effect
purchases, such agreements generally can be canceled by either party at will.
While the Company does have access to similar products from competing vendors,
the inability to obtain products from certain vendors, particularly Motorola,
would have a material adverse effect upon the Company. If Motorola experiences a
business interruption or other business problems, the Company could be
materially adversely affected. There can be no assurance that Motorola will
continue to grant the Company the right to distribute its products in its
current areas of operation or that Motorola will grant the Company the right to
distribute its products in areas served by offices that the Company may acquire
or open in the future. Also, the Company's status as a Motorola dealer in some
or all of its offices could be unilaterally terminated by Motorola. Termination
of the Company's status as a Motorola dealer would have a material adverse
effect on the Company. See "Business -- Growth Strategy" and
"Business -- Products and Services."
 
     Prior to 1987, a very high percentage of two-way radios were distributed
directly by their manufacturers. Since then, Motorola and other manufacturers
have increasingly distributed two-way radios via independent dealers, with the
exception of large accounts. There can be no assurance that this trend will
continue. Manufacturers could change their distribution strategy and begin to
distribute more or all two-way radios themselves or through distribution means
other than independent dealers. Such change would have a material adverse effect
on the Company. See "Business -- Industry Overview."
 
     Motorola offers a cooperative advertising program pursuant to which the
Company is permitted to claim reimbursements for certain expenses of up to a
percentage of the cost of certain inventory purchased, subject to certain
conditions. This program could be canceled, or the benefits available to the
Company thereunder could be significantly reduced, without the consent of the
Company. Any such cancellation or reduction could have a material adverse effect
on the Company. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Liquidity and Capital Resources."
 
INTERNATIONAL OPERATIONS
 
     In August 1995, the Company opened a field office in Sydney, Australia, and
in July 1997 the Company acquired a dealer in Brisbane, Australia. Revenues from
the Australia offices were less than 2% of the Company's net revenues in fiscal
1997 and the nine-month period ended January 31, 1998. Thus, the Company
historically has had limited experience with international operations. In March
1998, the Company completed the acquisition of Condor, which has distribution
sales offices in Caracas, Venezuela and Prague, Czech Republic. On a pro forma
basis, giving effect to the Condor Acquisition and the Other Acquisitions, the
Company's revenues in its 1997 fiscal year and for the nine-month period ended
January 31, 1998 that were derived from sales to customers outside of the United
States, or to other exporters who then sell such products to customers outside
of the United States, were 36.1% and 37.5%, respectively, with approximately
3.2% and 4.8% of the Company's revenues for such periods being derived from
sales to customers in Venezuela. The Company may open field offices in other
international markets or may acquire dealers with international operations. The
Company's success and plans for future growth in international markets will be
dependent on its ability to attract and retain qualified management personnel
for its international operations.
 
     Foreign operations and sales are subject to political and economic risks,
including political instability, currency controls, exchange rate fluctuations,
increased credit risks, foreign tax laws, changes in import/export regulations
and tariff and freight rates. Political and other factors beyond the control of
the Company, including trade disputes among nations or internal instability in
any nation where the Company conducts business, could have a material adverse
effect on the Company. There can be no assurance that the Company will be able
to successfully manage the risks presented by significant international
operations.

COMPETITION
 
     The two-way radio distribution industry is highly competitive and is
currently comprised of several regional and numerous local dealers. The
principal bases of competition in the industry are price and service. The sale
of two-way radios is a low-margin, high-volume business. Because awareness of
two-way wireless communication products is growing and the cost barriers to
entry into this market are relatively low, the risk of new competitors entering
this market is high. The Company believes that the industry will become more
competitive as the number of competitors increases and as new technologies
emerge. These factors, coupled with the growing industry emphasis on containing
costs, could place significant pressure on the Company to reduce prices, which
could significantly reduce the gross margins realized by the Company on sales of
its products.
 
     In addition, several manufacturers of two-way radio products, including
Motorola, also compete with independent distributors in selling, servicing and
renting two-way wireless communication products. There can be no assurance that
manufacturers of two-way radio products will continue to utilize independent
distributors in the future. In addition, there are several significantly large
global distributors of wireless communication products other than two-way
radios. These companies to date have not entered the two-way radio distribution
market in any significant way, but there can be no assurance that these
companies will not enter this industry in the future. These manufacturers and
distributors are much larger than the Company, and have substantially greater
capital resources, sales experience and distribution capabilities than the
Company. In response to competitive pressure from any of its current or future
competitors, the Company may be required to lower selling prices, which would
lower the Company's gross margins, which could have a material adverse effect on
the Company. See "Business -- Growth Strategy" and "Business -- Competition."
 
FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
 
     The Company has experienced material variations in quarterly revenues and
net income as a result of many factors including, among others, customer
relationships, catalog response rates, product blend, the level of selling,
general and administrative expense, weather conditions and the condition of the
wireless communication industry in general. For example, BearCom's net sales and
profits historically have been lower in the three months ended January 31 due to
lower levels of business activity during the winter months. In addition,
quarterly results may be materially affected by the timing of significant rental
activity, the timing of large system sales, seasonality in the ordering patterns
of users of the Company's products, seasonal buying patterns of dealers that
purchase products from Condor, the timing of new enhancements or product
offerings made available by suppliers, economic conditions in the geographical
areas in which the Company operates and the timing and magnitude of acquisitions
and related assimilation costs. Therefore, the operating results for any fiscal
quarter are not necessarily indicative of the results that may be achieved for
any subsequent fiscal quarter or for a full fiscal year. It is likely that the
Company will experience such fluctuations in the future. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
DEPENDENCE ON SYSTEMS
 
     The Company's success depends on the accuracy and proper utilization of its
management information systems. The Company's ability to manage its inventory
and accounts receivable collection; to purchase, sell and ship its products
efficiently and on a timely basis; and to maintain a cost efficient operation is
dependent upon the quality and utilization of the information generated by its
management information systems. The Company believes that its management
information system, coupled with planned enhancements, is sufficient to sustain
its present operations and its anticipated growth for the foreseeable future,
although no assurance can be given to that effect. The Company has adopted
procedures to protect its computer system and to provide for recovery in the
event of equipment failure. All system data is backed up to tape daily with
backup tapes stored off-site. Although the Company has not experienced a
significant failure in its computer system to date, there can be no assurance
that the Company will not experience such a failure in the future or that such
failure would not have a material adverse effect on the Company. In addition,
there can be no assurance that the Company's competitors will not develop
software applications similar to the proprietary software
 
                                        9
<PAGE>   11
 
developed by the Company or that such development would not have a material
adverse effect on the Company. See "Business -- Management Information System."
 
     The Company is in the process of modifying the software in its management
information system so that all of such software will be Year 2000 compliant.
There can be no assurance that the Company will timely complete such
modifications. Failure of the Company, its vendors or its customers to have in
place Year 2000 compliant systems could have a material adverse effect on the
Company. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Year 2000 Compliant Information Systems."
 
TECHNOLOGICAL CHANGE AND INVENTORY OBSOLESCENCE
 
     Management expects that much of the future growth in the wireless
communications industry will be based upon the introduction of new technologies,
such as digital transmission, and new services, such as satellite-based systems,
Personal Communication Services ("PCS") and Enhanced Specialized Mobile Radio
("ESMR"). The scope and technical attributes of many of these new technologies
and services have not been completely determined, and conflicting technologies
may be developed. In addition, technological advances could reduce the need for
continual product purchases by industry customers. To the extent that the
implementation of new technologies and services is delayed, or that new
technologies and services or reductions in airtime charges for new or existing
technologies and services reduce the need for the products offered by the
Company, the Company could be adversely affected. The Company maintains a
significant investment in its product inventory and, therefore, is subject to
the risk of inventory obsolescence. If a material amount of inventory is
rendered obsolete, the Company could be required to write-down the value of such
inventory and take a charge against earnings, which could have a material
adverse effect on the Company. In addition, if the Company is unable for any
reason to take advantage of marketing programs offered by vendors, it could be
materially and adversely affected.
 
RELIANCE ON MANAGEMENT
 
     The Company's success will depend to a significant extent upon the efforts
and abilities of certain key management personnel. The loss of the services of
the Company's key management personnel could have a material adverse effect on
the Company. The Company's success and plans for future growth will also be
dependent on its ability to attract and retain qualified employees in all areas
of its business. See "Management."
 
DISTRIBUTION COSTS; RELIABILITY RISKS
 
     Postage and shipping are significant expenses in the operation of the
Company's business. The Company ships its products to customers primarily by
United Parcel Service, as well as other overnight delivery and ground delivery
services, and mails its catalogs through the U.S. Postal Service. Any increases
in postal or shipping rates in the future could have a material adverse effect
on the Company. The cost of paper is also a significant expense of the Company
in printing its catalogs. Historically, paper prices have fluctuated from time
to time. Any future increases in the cost of paper could have a material adverse
effect on the Company.
 
     In August 1997, United Parcel Service experienced a labor strike that
adversely affected the Company both in terms of the service the Company was able
to provide as well as in terms of increased costs. A longer strike in the future
would likely have an even more significant adverse effect on the Company.
 
STATE SALES AND USE TAX
 
     Various states have sought to impose on direct marketers the burden of
collecting state use taxes on the sale of products shipped to those states'
residents. The United States Supreme Court has ruled that the various states,
absent Congressional legislation, may not impose tax collection obligations on
an out-of-state mail order company whose only contacts with the taxing state are
the distribution of catalogs and other advertisement materials through the mail
and whose subsequent delivery of purchased goods is by U.S. mail or interstate
common carriers. From time to time, legislation has been introduced in Congress
which, if passed, would impose state use tax collection obligations on
out-of-state mail order companies such as the Company.
                                       10
<PAGE>   12
 
If such legislation were to be enacted, the imposition of a tax collection
obligation on the Company may result in additional administrative expenses to
the Company and price increases to the customer that could adversely affect the
Company. Currently, the Company does not collect sales tax from customers in
states in which the Company does not maintain a sales office.
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
     Upon completion of the Offering, the Company will have outstanding
          shares of Common Stock. Of these shares, the           shares of
Common Stock sold in the Offering (          shares if the Underwriters'
over-allotment option is exercised in full) will be freely transferable without
restriction under the Securities Act of 1933 (the "Securities Act"), by persons
other than "affiliates" of the Company within the meaning of Rule 144
promulgated under the Securities Act ("Rule 144"). The remaining
shares of Common Stock were issued in reliance on exemptions from the
registration requirements of the Securities Act, and those shares are
"restricted" securities under Rule 144. For purposes of Rule 144, approximately
     shares held for more than one year will be eligible for sale beginning
approximately 90 days after the date of this Prospectus, based on current
Securities and Exchange Commission ("Commission") rules and subject to
compliance with the manner-of-sale, volume and other limitations of Rule 144.
 
     The Company has granted registration rights to its existing shareholders.
After the Offering, such shareholders will each have the right to require the
Company, subject to certain limitations, to include shares held by them in one
of the first four registrations of Common Stock by the Company. All shareholders
holding registration rights have waived their rights to participate as selling
shareholders in the Offering, except the Selling Shareholders in this Offering.
See "Principal and Selling Shareholders."
 
     Each of the Company, its officers and directors, and certain other
shareholders of the Company, including the Selling Shareholders, has agreed that
it will not (i) offer, pledge, sell, solicit an offer to buy, contract to sell,
grant any option, right or warrant to purchase, or otherwise transfer or dispose
of, directly or indirectly, or file with the Commission a registration statement
under the Securities Act relating to, any shares of Common Stock, or any
securities that are convertible into or exercisable or exchangeable for Common
Stock or (ii) enter into any swap or other arrangement that transfers all or a
portion of the economic consequences associated with ownership of any Common
Stock, for a period of 180 days after the date of this Prospectus without the
prior written consent of Donaldson, Lufkin & Jenrette Securities Corporation
("DLJ"), except pursuant to certain limited exceptions. See "Shares Eligible for
Future Sale" and "Underwriting."
 
     Future sales of substantial amounts of Common Stock, or the perception that
such sales could occur, may affect the market price of the Common Stock
prevailing from time to time.
 
NO PRIOR PUBLIC MARKET; OFFER PRICE; STOCK PRICE VOLATILITY
 
     Prior to this Offering, there has been no public market for the Company's
Common Stock, and there can be no assurance that following this Offering an
active trading market will develop or be maintained. The initial public offering
price will be determined by negotiations between the Company and the
representatives of the Underwriters and may not be indicative of prices that
will prevail in the trading market following this Offering. For a description of
the factors considered in determining the initial public offering price, see
"Underwriting." After the Offering, the market price of the Common Stock may be
influenced by many factors including, among others, the operating results of the
Company, investors' perceptions of the Company and its prospects, and general
economic and market conditions. In addition, the stock market has historically
experienced volatility which has particularly affected the market prices of
securities of many technology-related companies and which sometimes has been
unrelated to the operating performances of such companies. Furthermore, any
adverse changes in the market price of the common stock of other wireless
communication distribution or related companies or announcements of
technological developments may adversely affect the market price of the
Company's Common Stock, irrespective of whether there has been any deterioration
of the Company's business or financial results.

<PAGE>   13
 
CONTROL BY EXISTING SHAREHOLDERS
 
     Upon completion of this offering, the Company's officers and directors will
beneficially own approximately      % of the outstanding Common Stock. As a
result, these shareholders, acting together, may be able to control the outcome
of certain actions requiring shareholder approval, such as election of
directors, amendments to the Company's charter and mergers or other changes in
control. See "Principal and Selling Shareholders."
 
ANTI-TAKEOVER PROVISIONS
 
     The Texas Business Corporation Act and the Company's Articles of
Incorporation and Bylaws contain various provisions, including, without
limitation, certain provisions authorizing the Company to issue preferred stock
and dividing the Company's Board of Directors into three classes serving
staggered three-year terms, that may make it more difficult for a third party to
acquire, or may discourage acquisition bids for, the Company and could limit the
price that certain investors might be willing to pay in the future for shares of
the Company's Common Stock. The ownership after this Offering by the Company's
officers, directors and their affiliates of substantial shares of Common Stock
could also discourage such bids. In addition, the rights of the holders of
Common Stock will be subject to, and may be adversely affected by, the rights of
any holders of preferred stock that may be issued in the future and that may be
senior to the rights of the holders of Common Stock. The issuance of preferred
stock may have the effect of delaying, deterring or preventing a change in
control of the Company. See "Description of Capital Stock."
 
POSSIBLE HEALTH RISKS
 
     Recently, lawsuits have been filed alleging a link between the non-thermal
electromagnetic field emitted by cellular telephones and two-way radios and the
development of cancer. To date, there have been relatively few medical studies
relating to the effects of non-thermal electromagnetic fields on health, and
there are not any widely accepted theories regarding how exposure to a
non-thermal electromagnetic field could threaten health. Future medical studies
may produce findings that could have a material adverse effect upon the wireless
communications industry and the Company.
 
GOVERNMENT REGULATION
 
     From time to time, the Federal Communications Commission ("FCC") amends its
regulations governing the licensing or sale of the communication equipment
distributed by the Company, the frequencies that such equipment uses, and the
requirements for operating such equipment. The FCC has from time to time
submitted proposals relating to licensing, use and regulation of frequency bands
that could affect operation on certain of the frequency bands where equipment
marketed by the Company operates. It is uncertain what impact, if any, these or
future proposals may have on the Company's operations.
 
DILUTION; NO EXPECTATION OF DIVIDENDS
 
     This Offering will result in an immediate and substantial dilution to
purchasers of the Common Stock offered hereby because the net tangible book
value per share of the Common Stock after this Offering will be substantially
less than the initial public offering price per share. See "Dilution." For the
foreseeable future, it is anticipated that any earnings will be retained for
operations and expansion of the Company's business and that cash dividends will
not be paid to holders of the Common Stock. See "Prior S Corporation Status and
Dividend Policy."

                                  THE COMPANY
 
     In December 1995, the Company (then named Page-Com, Inc.) consummated the
Merger with Bear Communications. Bear Communications was a leading independent
distributor of wireless communication products in the United States through the
field office channel and Page-Com was a leading independent distributor of
wireless communication products in the United States through catalog operations.
The Merger was accounted for as a pooling of interests. From August 1996 through
February 1998, the Company acquired the operations of 12 independent dealers of
wireless communication products and a majority of the assets of Motorola's Radio
Products Group rentals business. All such acquisitions were accounted for as
purchases for financial reporting purposes.
 
     On March 31, 1998, the Company completed the Condor Acquisition. Condor
reported revenues of $51.4 million during its fiscal year ended December 31,
1997. The Condor Acquisition was accounted for using the purchase method of
accounting. Based in Miami, Florida, Condor is a leading exporter of two-way
radio communication equipment and communication systems primarily to Latin
America, Eastern Europe, Africa and the Middle East. In addition to its Miami
office, Condor operates a distribution sales office in Prague, Czech Republic.
Condor owns a fifty percent interest in an entity that operates a distribution
sales office in Caracas, Venezuela. Condor exports primarily Motorola two-way
radio products. Virtually all of Condor's sales are denominated in U.S. dollars.
The Condor Acquisition provides the Company an operational platform from which
it can expand its international operations. The Company's strategy is to expand
its international operations by establishing additional sales offices within
licensed regions and offering additional products and services within those
regions.
 
     The Company's principal executive offices are located at 11545 Pagemill
Road, Dallas, Texas 75243 and its telephone number is (214) 340-8876.
 
                                USE OF PROCEEDS
 
     The net proceeds to be received by the Company from the sale of the shares
of Common Stock offered by the Company hereby (after deducting underwriting
discounts and commissions and estimated offering expenses) are estimated to be
approximately $       , assuming an initial public offering price of $       . A
portion of the net proceeds will be used to repay all of the Company's
borrowings under its $25 million revolving line of credit and its $5 million
term note (the "Senior Bank Facility"), approximately $23.6 million at March 31,
1998. The Company is required to repay the amount of all principal outstanding
under the term note, approximately $4.6 million at March 31, 1998, in equal
monthly installments through November 5, 2001. The Company may re-borrow funds
under the revolving line of credit from time to time. All outstanding amounts
under the revolving line of credit are due and payable on November 5, 1999. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources." The revolving line of credit and
the term note each bear interest at a floating rate (6.86% and 6.98%,
respectively, at March 31, 1998). The balance of the net proceeds will be used
for general corporate purposes, including working capital, and would be
available to finance, among other things, potential strategic acquisitions and
upgrades to the Company's management information systems. The Company is
currently evaluating certain strategic acquisitions; however, the Company has no
binding commitment to acquire any business or other material assets. Pending
such uses, the net proceeds of the Offering will be invested in short-term,
interest-bearing securities. Other than as a result of the anticipated repayment
to the Company of a promissory note from a Selling Shareholder with the proceeds
from shares of Common Stock to be sold by him in the Offering, the Company will
not receive any proceeds from the sale of shares by the Selling Shareholders.
See "Management -- Certain Transactions."

                 PRIOR S CORPORATION STATUS AND DIVIDEND POLICY
 
     For all taxable periods prior to January 1, 1995, Bear Communications was a
corporation subject to taxation under Subchapter S of the Internal Revenue Code
of 1986, as amended (the "Code"). On January 1, 1995, Bear Communications
terminated its "S" corporation status. In connection with this termination, Bear
Communications made distributions aggregating approximately $423,000 to its
shareholders. Other than these distributions, the Company has not paid dividends
on its Common Stock during the last two fiscal years. The Company expects that
in the foreseeable future it will retain all available earnings, if any, for the
development and growth of its businesses and does not anticipate paying any cash
dividends on the Common Stock. The Senior Bank Facility prohibits paying
dividends while any amounts are outstanding thereunder. Subject to this
restriction, the payment of cash dividends in the future will be at the
discretion of the Board of Directors and will depend upon such factors as the
Company's future earnings, capital requirements, financial condition and
business prospects and other factors the Board of Directors deems relevant.

                                    DILUTION
 
     At January 31, 1998, the net tangible book value of the Company was
approximately $5.2 million or $          per share of Common Stock. Net tangible
book value per share is determined by dividing the tangible net worth of the
Company (total tangible assets less total liabilities) by the number of shares
of Common Stock outstanding. After giving effect to the sale by the Company of
the shares of Common Stock offered hereby at an assumed initial public offering
price of $          per share and the deduction of the estimated underwriting
discounts and commissions and Offering expenses payable by the Company in
connection therewith, but without taking into account any other changes in such
net tangible book value, the net tangible book value of the Company at January
31, 1998 would have been approximately $     million or $          per share.
This represents an immediate increase in net tangible book value of $
per share to existing shareholders and an immediate dilution in net tangible
book value of $          per share to purchasers of shares in this Offering. The
following table illustrates this dilution:

(1) Sales by the Selling Shareholders in this Offering will reduce the number of
    shares held by existing shareholders of the Company to           , or      %
    of the total number of shares outstanding after this Offering, and will
    increase the number of shares held by new investors to           shares, or
         % of the total number of shares outstanding after this Offering. See
    "Principal and Selling Shareholders."
 
     The computations in the table set forth above assume no exercise of
outstanding stock options. On the date of this Prospectus, there were
outstanding options to purchase           shares of Common Stock at the Offering

        UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
     The unaudited pro forma condensed consolidated financial statements are
included in order to illustrate the effect on the Company's financial statements
of the transactions described below.
 
     The unaudited pro forma condensed consolidated balance sheet at January 31,
1998 gives effect to (i) the Condor Acquisition (based on the audited balance
sheet of Condor as of December 31, 1997) and (ii) the Offering and the
application of the net proceeds therefrom (and related repayment of shareholder
notes) as if these transactions had occurred on January 31, 1998. All
acquisitions by the Company, other than the Condor Acquisition, were completed
by January 31, 1998 and are reflected in the unaudited pro forma condensed
consolidated balance sheet at January 31, 1998.
 
     The unaudited pro forma condensed consolidated statements of income for the
year ended April 30, 1997 and the nine months ended January 31, 1998 give effect
to (i) the Condor Acquisition and Other Acquisitions and (ii) the Offering and
the application of the net proceeds therefrom (and repayment of shareholder
notes) as if these transactions had occurred on May 1, 1996. As used herein,
"Other Acquisitions" reflects the activity for the period from May 1, 1996 to
the respective closing dates of the acquisitions of seven acquired businesses.
Activity of the remaining five acquisitions are not included due to the
immateriality of four of the acquired businesses and the impracticability of
obtaining information relating to the acquisition of a majority of the assets of
Motorola's Radio Products Group rentals business. The unaudited pro forma
condensed consolidated income statement for the year ended April 30, 1997
includes the results of Condor for the twelve-month period ended March 31, 1997.
The unaudited pro forma condensed consolidated income statement for the nine
months ended January 31, 1998 includes the results of Condor for the nine-month
period ended December 31, 1997.
 
     The unaudited pro forma adjustments are based upon available information
and certain assumptions that the Company believes are reasonable, and in the
opinion of management, include all adjustments necessary to present fairly the
pro forma financial information. The pro forma financial statements and
accompanying notes should be read in conjunction with the historical
consolidated financial statements of the Company and Condor, and other financial
information pertaining to the Company, including the information set forth under
the captions "The Company," "Capitalization" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations" included elsewhere
herein. The unaudited pro forma condensed consolidated statements of income are
not indicative of either future results of operations or the results that might
have occurred if the foregoing transactions had been consummated on the
indicated dates.

    that Condor could be obligated to pay pursuant to an earn-out arrangement
    entered into in connection with the Condor Acquisition. See "Management's
    Discussion and Analysis of Financial Condition and Results of Operation."

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following provides an analysis of the Company's financial condition and
results of operations, and should be read in conjunction with "Selected
Financial Data" and the Consolidated Financial Statements and the notes thereto
included elsewhere in this Prospectus. Except for the historical information
contained herein, the discussion in this Prospectus contains forward-looking
statements that involve risks and uncertainties. The Company's actual
performance or results could differ materially from those discussed herein.
Factors that could contribute to such differences include those discussed below
and in the section entitled "Risk Factors," as well as those discussed elsewhere
in this Prospectus.
 
OVERVIEW
 
     The Company is principally engaged in the business of selling, renting and
servicing site-based two-way communication equipment and accessories. In
December 1995, the Company (then named Page-Com, Inc.) consummated the Merger
with Bear Communications. Prior to the Merger, the Company believes that Bear
Communications was the largest independent distributor of two-way radios in the
United States through the field office channel and Page-Com was the largest
independent distributor of two-way radios in the United States through the
catalog marketing channel. As a result of the Merger, which was accounted for as
a pooling of interests, the Company's Consolidated Financial Statements have
been restated to include the accounts and operations of Page-Com and Bear
Communications for all periods presented. From August 1996 through February
1998, the Company acquired the operations of 12 independent dealers of wireless
communication products and a majority of the assets of Motorola's Radio Products
Group rentals business. On March 31, 1998, the Company consummated the Condor
Acquisition. All such acquisitions were accounted for as purchases for financial
reporting purposes. Accordingly, the results of operations of such acquired
businesses are included in the Company's results of operations from the dates of
acquisition.
 
     The Company's acquisitions have enabled it to enter new domestic and
international markets and increase penetration of existing markets, resulting in
significant sales growth since commencing its acquisition program in August
1996. Acquisitions generally have been financed through the use of the Senior
Bank Facility. During the initial integration phase following an acquisition,
the Company typically has incurred integration-related operating expenses for
training personnel, for the conversion of information systems and other
transition-related costs. Depending on the size and location of an acquired
business, integration costs have been incurred primarily during the first six
months following an acquisition.
 
     The Company's revenues are derived from sales to end-users in a wide
variety of industries, other wireless communication dealers and rental
customers. For the fiscal years ended April 30, 1996 and 1997 and the nine
months ended January 31, 1998, revenues derived from sales to other wholesale
wireless communication dealers accounted for less than 10% of the Company's
revenues. However, as a result of the Condor Acquisition, the Company expects
that revenues from sales to other wholesale wireless communication dealers will
account for a significantly higher percentage of the Company's revenues for
periods subsequent to such acquisition. Additionally, for the last two fiscal
years, no single customer accounted for more than 5% of the Company's revenues.
 
     From May 1, 1996 through January 31, 1998, 81% of the Company's revenues
was derived from the sale of equipment, while 12% was attributable to rental
revenues, 5% to repair revenues and 2% to other revenues. Other revenues
includes revenues from sales of paging services and Nextel activation fees.
Gross profit margins related to rental and repair revenues historically have
been significantly higher than that of revenues derived from the sale of
equipment and accessories.

  NINE MONTHS ENDED JANUARY 31, 1998 COMPARED TO NINE MONTHS ENDED JANUARY 31,
1997
 
     Revenues. Revenues increased $15.7 million, or 30.6%, to $67.1 million for
the nine months ended January 31, 1999 compared to $51.4 million for the nine
months ended January 31, 1997. Of the overall revenue increase, approximately
$10.4 million was related to revenues included from ten businesses acquired
subsequent to January 31, 1997. The remaining $5.3 million increase related to
internal revenue growth from the Company's sales offices existing as of January
31, 1997 and catalog operations. Overall, revenues were not impacted by any
significant price changes. Increases by revenue components were as follows:
equipment revenues increased $10.1 million, or 23.6%; rental revenues increased
$2.0 million, or 30.6%; repair revenues increased $2.4 million; and other
revenues increased $1.3 million. Excluding approximately $800,000 of rental
revenue generated from the 1996 Summer Olympic Games, rental revenues increased
$2.8 million, or 49.1%, during the nine months ended January 31, 1998. This
increase was primarily related to the Company's acquisition of a majority of the
assets of Motorola's Radio Products Group rentals business in June 1997 as well
as rental revenues attributable to other acquired businesses. Of the $2.4
million increase in repair revenues, approximately $1.4 million is attributable
to acquired businesses with the remaining $1.0 million increase attributable to
existing repair services. Additionally, the increase in other revenues is
attributable to increased activation income earned from the sale of Nextel
equipment.
 
     Gross profit. Gross profit increased $5.6 million, or 32.8%, to $22.7
million for the nine months ended January 31, 1998 compared to $17.1 million for
the nine months ended January 31, 1997. Of the overall gross profit increase,
$3.6 million was attributable to acquired businesses. Gross profit margin
increased from 33.2% for the nine months ended January 31, 1997 to 33.8% for the
nine months ended January 31, 1998, primarily as a result of a higher percentage
of revenues being derived from repair and other revenues. The increase in gross
profit margin was partially offset by a decrease in gross profit margins related
to revenues derived from equipment sales, primarily due to the elimination
during 1997 of a special rebate program from a manufacturer.
 
     Operating expenses. Operating expenses increased by $4.7 million, or 33.7%,
to $18.8 million for the nine months ended January 31, 1998 compared to $14.1
million for the nine months ended January 31, 1997. As a percentage of revenues,
operating expenses were 28.1% and 27.4% for the nine months ended January 31,
1998 and 1997, respectively. Of the increase in operating expenses,
approximately $3.0 million was attributable to
 
                                       23
<PAGE>   25
 
acquired businesses. Other increases related to administrative costs to
facilitate the Company's growth, as well as printing and postage costs
associated with an increase in the number of catalogs mailed during the nine
months ended January 31, 1998 compared to the same period in 1997.
 
     Interest expense. For the nine months ended January 31, 1998, interest
expense increased $415,000 to $847,000, from $432,000 for the nine months ended
January 31, 1997. The increase was primarily attributable to increased
borrowings to finance the Company's acquisition activity during the year. The
increase was offset in part by lower interest rates as a result of the Company
amending its revolving credit facility at November 1, 1996.
 
     Other, net. For the nine months ended January 31, 1998, other, net remained
relatively constant compared to the nine months ended January 31, 1997.
 
     Income tax expense. The effective income tax rate for the nine months ended
January 31, 1998 was 36.3%, compared to 38.4% for the nine months ended January
31, 1997. The Company's effective income tax rate differs from the statutory
rate primarily as a result of provisions made for state income taxes.
 
  YEAR ENDED APRIL 30, 1997 COMPARED TO YEAR ENDED APRIL 30, 1996
 
     Revenues. Revenues increased $6.3 million, or 10.0%, to $69.6 million for
the year ended April 30, 1997 compared to $63.3 million for the year ended April
30, 1996. Of the overall revenue increase, approximately $2.6 million was
related to revenues included from three businesses acquired subsequent to April
30, 1996. The remaining $3.7 million increase related to internal revenue growth
from the Company's existing sales offices and catalog operations. Overall,
revenues were not impacted by any significant price changes. Increases by
revenue components were as follows: equipment revenues increased $3.7 million,
or 6.9%; rental revenues increased $2.1 million, or 33.5%; repair revenues
increased $402,000, or 19.4%; and other revenues increased $93,000, or 13.3%.
During September 1995, the Company discontinued selling to a customer that
accounted for approximately $2.1 million of its equipment revenues for the year
ended April 30, 1996. That customer was a chain of discount warehouse clubs that
ceased selling two-way radios and instead allowed a third party to sell two-way
radios in kiosks located in those warehouse clubs. Excluding this revenue,
overall revenues and equipment revenues for the year ended April 30, 1997 would
have increased 13.9% and 11.3%, respectively. Additionally, excluding
approximately $0.8 million of rental revenues generated from the 1996 Summer
Olympic Games, rental revenues increased $1.3 million, or 21.0%, during the year
ended April 30, 1997 compared to the year ended April 30, 1996.
 
     Gross profit. Gross profit increased by $3.1 million, or 15.1%, to $23.4
million for the year ended April 30, 1997 compared to $20.3 million for the year
ended April 30, 1996. Of the overall gross profit increase, $1.1 million was
attributable to the three businesses acquired subsequent to April 30, 1996.
Gross profit margin increased from 32.1% for the year ended April 30, 1996 to
33.6% for the year ended April 30, 1997, primarily as a result of the loss of
sales to a significant customer, which sales resulted in below-average gross
profit margins. Additionally, overall gross profit margins increased primarily
as a result of a higher percentage of revenues being derived from rental and
repair revenues, which have historically provided the Company significantly
higher gross profit margins.
 
     Operating expenses. Operating expenses increased by $3.1 million, or 18.3%,
to $19.8 million for the year ended April 30, 1997 compared to $16.7 million for
the year ended April 30, 1996. As a percentage of revenues, operating expenses
were 28.4% and 26.4% for the years ended April 30, 1997 and 1996, respectively.
Of the increase in operating expenses, approximately $0.9 million was
attributable to acquired businesses. Additionally, operating expenses increased
as a result of increased administrative costs for a full year associated with
the Merger in December 1995 and an increase in freight costs resulting from a
change in the Company's freight program, which increase was not passed on to its
customers.
 
     Interest expense. For the year ended April 30, 1997, interest expense
increased $51,000 to $595,000 from $544,000 for the year ended April 30, 1996.
The net increase was primarily attributable to increased borrowings to finance
the Company's acquisitions during the year, which increase was partially offset
by lower interest rates as a result of the Company amending its revolving credit
facility on November 1, 1996.
 
                                       24

     Other, net. Other income for the year ended April 30, 1997 was $73,000
compared to other expense of $33,000 for the year ended April 30, 1996. For the
year ended April 30, 1997, other income was primarily related to interest income
from notes receivable from an officer of the Company. For the year ended April
30, 1996, other expense is primary attributable to legal and professional fees
that were incurred in connection with the Merger.
 
     Income tax expense. The effective income tax rate for the year ended April
30, 1997 was 38.4%, compared to 38.8% for the year ended April 30, 1996. The
Company's effective income tax rate differs from the statutory rate primarily as
a result of provisions made for state income taxes.
 
  YEAR ENDED APRIL 30, 1996 COMPARED TO YEAR ENDED APRIL 30, 1995
 
     Revenues. Revenues increased $6.7 million, or 11.9%, to $63.3 million for
the year ended April 30, 1996 compared to $56.6 million for the year ended April
30, 1995. Of the overall revenue increase, approximately $1.9 million was
related to revenues included from four new sales offices opened during the
second half of fiscal 1995. The remaining $4.8 million increase related to
internal revenue growth from the Company's existing sales offices and catalog
operations. Overall, revenues were not impacted by any significant price
changes. Increases by revenue components were as follows: equipment revenues
increased $5.4 million, or 11.2%; rental revenues increased $632,000, or 11.0%;
repair revenues increased $488,000, or 30.8%; and other revenues increased
$159,000, or 29.4%. During September 1995, the Company discontinued selling to a
customer that accounted for approximately $2.1 million and $4.6 million of
revenues for the years ended April 30, 1996 and 1995, respectively. Excluding
these revenues from both fiscal years, overall revenues and equipment revenues
increased 17.7% and 18.0%, respectively, for fiscal 1996 compared to fiscal
1995.
 
     Gross profit. Gross profit increased $3.1 million, or 18.1%, to $20.3
million for the year ended April 30, 1996 compared to $17.2 million for the year
ended April 30, 1995. Of the overall gross profit increase, $833,000 was
attributable to four new sales offices opened during the second half of fiscal
1995. Gross profit margin increased from 30.4% for the year ended April 30, 1995
to 32.1% for the year ended April 30, 1996. The increase in gross profit margin
was primarily due to the loss of sales to a significant customer in September
1995, which sales resulted in below average gross profit margins. Excluding
sales to the customer discontinued in September 1995, gross profit margins
related to overall revenues increased to 35.8% for the year ended April 30, 1996
compared to 34.6% for the year ended April 30, 1995. This increase was primarily
attributable to the Company taking advantage of purchase incentives offered by a
significant vendor. Gross profit margins were not affected by the Company's
revenue blend because the percentage of revenues related to equipment, rental,
repair labor and other remained relatively constant between fiscal years.
 
     Operating expenses. Operating expenses increased by $3.1 million, or 22.6%,
to $16.7 million for the year ended April 30, 1996 compared to $13.6 million for
the year ended April 30, 1995. As a percentage of revenues, operating expenses
were 26.4% and 24.1% for the years ended April 30, 1996 and 1995, respectively.
The increase in operating expenses as a percentage of revenue was affected by
approximately $571,000 of expenses incurred at sales offices opened during
fiscal 1996. Additionally, operating expenses increased as a result of increased
administrative costs associated with the Merger in December 1995 and changes
made to the Company's commission program for its field sales representatives,
which changes had the effect of increasing commission expense during fiscal
1996, both in dollars and as a percentage of revenues.
 
     Interest expense. For the year ended April 30, 1996, interest expense
remained relatively constant and increased $25,000 to $544,000.
 
     Other, net. Other expense for the year ended April 30, 1996 was $33,000
compared to $302,000 for the year ended April 30, 1995. Other expense for the
year ended April 30, 1995 included a loss of approximately $180,000 related to
the sale of the Company's former corporate office in Dallas, Texas.
 
     Income tax expense. The effective income tax rate for the year ended April
30, 1996 was 38.8%, compared to 63.0% for the year ended April 30, 1995. For
periods prior to January 1, 1995, Bear Communications was subject to taxation
under Subchapter S of the Code. Effective January 1, 1995, Bear Communications
elected to terminate its "S" corporation status and also changed its method of
accounting for
 
                                       25
<PAGE>   27
 
income tax purposes from the cash basis to the accrual basis. The change in tax
status resulted in a charge to income tax expense of $693,000 for the year ended
April 30, 1995. On a pro forma basis, the effective income tax rate for the year
ended April 30, 1995 was 38.7%. The Company's effective income tax rate differs
from the statutory rate primarily as a result of provisions made for state
income taxes.

     The Company's business is subject to seasonal influences and accordingly,
its revenues and operating results are typically lower during the fiscal quarter
ending January 31 due to lower levels of business activity during the winter
months. The Company's revenues and operating results may be subject to further
fluctuation in future periods. Significant quarterly fluctuations in the
Company's revenue and operating results may be caused by, among other factors,
the timing of significant rental activity, seasonality in the ordering patterns
of users of the Company's products, the timing of new enhancements or product
offerings made available by suppliers, economic conditions in the geographical
areas in which the Company operates and acquisitions and related assimilation
costs. See "Risk Factors -- Fluctuations in Quarterly Operating Results."
 
CONDOR COMMUNICATIONS, INC.
 
     On March 31, 1998, the Company acquired substantially all of the assets of
Condor Communications, Inc., a leading exporter of two-way communication
equipment and communication systems to dealers primarily in Latin America and
Eastern Europe. The acquisition was accounted for using the purchase method of
accounting. Condor is based in Miami, Florida and has distribution offices in
Caracas, Venezuela and Prague, Czech Republic.
 
                                       26
<PAGE>   28
 
     Condor reported revenues of $51.4 million during the twelve months ended
December 31, 1997, an increase of 10.5% from revenues of $46.5 million in 1996.
This increase was due to increased shipments of two-way equipment to dealers.
Condor's gross profit decreased to $6.1 million in 1997 from $8.1 million in
1996. Condor's gross margin decreased to 11.9% in 1997 from 17.6% in 1996.
Condor's decreased gross profit and gross margin in 1997 was primarily due to
decreased sales of MPT-1327 systems, which have higher gross margins than
Condor's other products, and a reduction of sales in Eastern Europe, which
historically have resulted in higher gross margins than sales in other regions.
Condor's selling, general and administrative expenses decreased to $2.8 million
in 1997 from $3.9 million in 1996, primarily due to a reduction in bad debt
expense for 1997 compared to 1996. As a percentage of revenue, Condor's selling,
general and administrative expenses decreased to 5.5% in 1997 from 8.4% in 1996.
Condor's operating income decreased to $3.3 million, or 6.4% of revenue in 1997
from $4.3 million or 9.1% of revenue in 1996.
 
     The Company's historical financial information included in this Prospectus
does not include the operations of Condor in any periods presented. As a result
of the Condor Acquisition, the Company expects that its consolidated gross
profit margin will decline in future periods due to the inclusion of Condor's
export operations, which have had significantly lower gross profit margins than
the Company's domestic operations. However, because Condor's operating expenses
as a percentage of revenues historically have been lower than that of BearCom,
Condor historically has experienced higher operating income margins than
BearCom. Condor's business is subject to seasonal influences and, accordingly,
its quarterly revenues and operating results may be materially affected by the
timing of large system sales, seasonal buying patterns of dealers, the timing of
new enhancements or product offerings made available by suppliers and economic
conditions in the geographical areas in which it operates.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company historically has generated positive cash flows from operations.
In fiscal years 1995 and 1996, the Company generated $2.1 million and $3.1
million of cash flows from operations, respectively. During fiscal 1997 and the
nine months ended January 31, 1998, the Company used approximately $152,000 and
$58,000, respectively of cash in its operating activities. Additionally, capital
expenditures for property and equipment totaled approximately $1.1 million, $1.6
million, $2.1 million and $0.9 million for the years ended April 30, 1995, 1996
and 1997 and the nine months ended January 31, 1998, respectively. Significant
capital expenditures in each period were made primarily to purchase equipment to
update the Company's rental radio fleet. Since August 1996, the Company has
acquired the operations of 12 independent dealers of wireless communication
products, and a majority of the assets of Motorola's Radio Products Group
rentals business and Condor for aggregate consideration of $17.2 million in
cash, notes payable in the amount of $300,000 and amounts to be paid pursuant to
certain earn-out arrangements. As part of the Condor Acquisition, the Company
entered into an earn-out arrangement pursuant to which the Company is obligated
to pay Condor Communications, for each of the first two twelve-month periods
following the consummation of the Condor Acquisition, an amount equal to fifty
percent of the first $3.0 million of EBITDA attributable to Condor Business Unit
Operations (as defined in the agreement governing the Condor Acquisition),
provided that EBITDA for such twelve-month period shall be $2.0 million or
greater, and twenty-five percent of EBITDA in excess of $3.0 million.
 
     In addition to cash flows from operations, the Company's principal source
of liquidity is borrowings under the Senior Bank Facility. The Senior Bank
Facility is comprised of (i) a $25 million revolving line of credit maturing
November 5, 1999 that may be used for working capital, general corporate
purposes and strategic acquisitions and (ii) a $5 million term loan requiring
monthly payments of $104,167 plus accrued interest through November 5, 2001. At
the Company's option (subject to certain terms and conditions), borrowings under
the Senior Bank Facility bear interest at either an adjusted LIBOR rate plus a
margin (1.25% in the case of the revolving line of credit and 1.35% in the case
of the term loan) or at the lender's prime commercial rate. Borrowings under the
Senior Bank Facility are secured by substantially all of the assets of the
Company. Additionally, the Company is entitled to prepay amounts from time to
time, in whole or part, without notice or penalty.
 
                                       27
<PAGE>   29
 
     The maximum amount of borrowings under the revolving line of credit is the
lesser of $25 million or a multiple of "free cash flow" of the Company, as
defined under the Senior Bank Facility. As of March 31, 1998, the Company had
approximately $19.0 million of borrowings outstanding under the revolving line
of credit and approximately $6.0 million available for further advances
thereunder. The Senior Bank Facility requires, among other things, that the
Company maintain certain amounts of tangible working capital, not less than
$1,000 of quarterly net income and certain ratios with regard to debt and
tangible net worth.
 
     As of January 31, 1998, the Company had working capital of approximately
$15.7 million and a current ratio of 2.5:1, compared to working capital of
approximately $13.2 million and a current ratio of 3.3:1 as of April 30, 1997.
The Company's trade accounts receivable balances at April 30, 1996 and 1997 and
January 31, 1998 were $6.7 million, $8.8 million and $13.8 million,
respectively. The increase in accounts receivable is primarily related to the
Company's increase in revenues resulting from acquisitions and internal growth.
The average days sales outstanding for accounts receivable was approximately 42
days at April 30, 1997 and approximately 47 days at January 31, 1998.
 
     The Company is offered discounts from several of its principal suppliers
for certain inventory purchases, with discounts ranging from 2% to 4% if the
Company pays within fifteen days. The Company historically has taken advantage
of these discounts. For the years ended April 30, 1996 and 1997 and the nine
months ended January 31, 1998, discounts totaling $0.9 million, $1.7 million and
$0.9 million, respectively, were taken by the Company. Additionally, the
Company's principal supplier offers a cooperative advertising program pursuant
to which the Company is permitted to claim reimbursements for certain expenses
of up to 3% of certain inventory purchased. Reimbursements are contingent upon
the Company supporting specific advertising expenses incurred in accordance with
policies and procedures established by the supplier. For the years ended April
30, 1996 and 1997 and the nine months ended January 31, 1998, the Company offset
operating expenses by $447,000, $608,000 and $440,000, respectively, relating to
this reimbursement program. Although there can be no assurance that such
programs will be continued, they have been common in the Company's industry for
many years and have routinely been offered by several of its principal
suppliers. If, however, these programs were changed or terminated, the Company's
liquidity requirements could increase materially and results of operations could
be adversely affected.
 
     The Company believes its cash flow from operations, the net proceeds of the
offering made hereby and utilization of available amounts under the Senior Bank
Facility will be adequate to provide for its working capital needs, future
expansion, including opening new sales offices or acquiring additional wireless
communication businesses, and planned capital expenditures in the next fiscal
year.
 
YEAR 2000 COMPLIANT INFORMATION SYSTEMS
 
     The Company uses software and related technologies throughout its business
that will be affected by the Year 2000 problem, which is common to most
businesses, and concerns the inability of information systems, primarily
computer software programs, to properly recognize and process date sensitive
information as the year 2000 approaches. The Company is in the process of
modifying the software in its management information system so that all of such
software will be Year 2000 compliant. The Company believes that it will be able
to modify all such software in time to minimize any detrimental effects on
operations. There can be no assurance that the Company will timely complete such
modifications. While it is not possible, at this time, to give an accurate
estimate of the cost of this work, the Company expects that such costs will not
be material to the Company's results of operations. Failure of the Company, its
vendors or its customers to have in place Year 2000 compliant systems could have
a material adverse effect on the Company.
 
AUTHORITATIVE PRONOUNCEMENTS
 
     The Financial Accounting Standards Board has issued Statements of Financial
Accounting Standards No. 130 "Reporting Comprehensive Income" and No. 131
"Disclosures about Segments of an Enterprise and Related Information," which are
required to be adopted in fiscal 1999. Statement 130 will require the Company to
report comprehensive income and its components with the same prominence as other
financial statements. Statement 131 is not expected to significantly change the
Company's current disclosures.

                                    BUSINESS
 
GENERAL
 
     The Company is the largest independent distributor of two-way radios in the
world with leading positions in the field sales, catalog sales, export sales and
rental segments of the market. The Company sells, services and rents a broad
line of two-way radios manufactured by industry leaders including Motorola,
Maxon, Icom and Tekk, which are used to communicate within a limited geographic
area without incurring airtime or subscriber charges. In the United States, the
Company's diverse customer base consists primarily of businesses and
organizations across a wide variety of industries, whereas internationally the
Company's customers generally are dealers which, in turn, sell to similar end
users. In addition to its two-way radio product line, the Company sells
complementary wireless communication and related products and services,
including Orbacom console systems, Motorola messaging systems, Nextel handsets
and services and PageMart pagers and services.
 
     Through BearCom, the Company markets its products and services through 34
field offices in the United States and two in Australia and through its catalog
operations throughout the United States. In addition, through Condor, the
Company exports its products and services through its distribution offices in
Miami, Florida, Caracas, Venezuela and Prague, Czech Republic. The Company
believes that it is the only significant distributor of two-way radios
leveraging the strengths of these multiple channels of distribution. Through its
field offices, BearCom provides technical assistance for customers requiring
on-site evaluation of their communications needs. For customers not requiring
this consultative approach (usually when system needs are relatively
uncomplicated or purchases are add-on or replacement units to an existing
system), the catalog marketing channel provides an efficient and convenient
method of purchasing products. During fiscal 1997, BearCom mailed more than 4.4
million catalogs and marketing pieces and processed in excess of 150,000
customer orders. Most orders are processed and shipped on the same day they are
received. The Company uses sophisticated information systems and proprietary
software to monitor and refine its customer database, catalog mailings and
inventory levels. In addition, the Company has a fleet of over 15,000 two-way
radios for rent, which are used in connection with sporting events, conventions,
disaster recovery projects, motion picture productions and other events. The
Company believes that it is the largest renter of two-way radios in the United
States.
 
     From fiscal 1993 to fiscal 1997, the Company's revenues grew, primarily as
a result of internal growth and the opening of nine new sales offices, from
$37.9 million to $69.6 million, representing a compound annual growth rate of
approximately 16%. Since August 1996, the Company has accelerated its growth
through the acquisition of the operations of 12 independent dealers, a majority
of the assets of Motorola's Radio Products Group rentals business and
substantially all of the assets of Condor. As a result, revenues for the nine
months ended January 31, 1998 were $67.1 million, a 31% increase from revenues
generated during the equivalent period of the prior fiscal year. On a pro forma
basis, giving effect to the Condor Acquisition and the Other Acquisitions, the
Company's revenues were $131.4 million and $112.7 million during fiscal 1997 and
the nine months ended January 31, 1998, respectively. The Company intends to
make additional acquisitions to establish a presence in new geographic areas and
to enhance its presence in existing markets. In pursuing such acquisitions, the
Company typically seeks to gain access to the acquired dealer's skills,
experience and customer relationships, while consolidating its fulfillment
operations into existing facilities.
 
     The Company's objective is to expand its position as the largest
independent distributor of two-way radios and related products in the world and
be the leading independent distributor in each market in which it serves. The
Company's strategy is to further develop its network of field offices by opening
and acquiring local operations, expand and enhance its catalog and export
operations, leverage its complementary distribution channels by expanding its
product and service offerings, and support such operations with rapid order
fulfillment and superior customer service and technical support. The Company
seeks to capitalize on its experience and reputation derived from more than 15
years of selling and marketing two-way radio products in executing its strategy
and addressing its market opportunity.

INDUSTRY OVERVIEW
 
     The Company's principal focus is selling, servicing and renting site-based
wireless communication products. While the Company is not aware of any
definitive industry data, the Company believes that the market for the sale,
rental and service of two-way radios and related products is in excess of $5
billion per year in the United States and an additional $5 billion per year
outside the United States. Site-based wireless communication products allow
teams of workers to have immediate voice communication over distances generally
ranging from a few hundred feet to up to three to five miles. The Company
believes that such communication can substantially enhance business
productivity. Unlike most other forms of wireless communication products,
site-based two-way radios require no air-time or subscriber charges and are
utilized almost exclusively in business applications. Individual radios
generally range in price from $200 to $1,000 based upon the size and features of
the unit. Depending on the application, users typically require from as a few as
two radios to as many as several hundred. Applications for site-based two way
radios span many industries. Common examples include:
 
     The plant manager of a manufacturing facility coordinates the activities of
     15 maintenance and repair employees across several buildings in a 150,000
     square foot industrial complex.
 
     The three-person staff of a law firm's MIS department communicates with one
     another across multiple floors of an office building to respond rapidly to
     service requests.
 
     The coordinators of a major sporting event require five independent systems
     (security, parking, parade, concession and press personnel) each requiring
     more than 100 radios communicating across a three-mile radius. The
     coordinators rent the equipment for the two-day event.
 
     The golf course superintendent of a top-of-the-line golf course and country
     club coordinates the activities of each of his greenskeepers. In addition,
     the pro shop coordinates its course marshals, each of whom carry a two-way
     radio.
 
     An airline's station chief manages ground operations personnel as well as
     customer service representatives throughout its terminal with two-way
     radios.
 
     The manager of a petrochemical complex manages engineering, maintenance and
     security personnel throughout the 100-acre facility.
 
     Growth in this segment of the wireless communications market has been
driven by several factors. The Company believes that the rapid emergence of
wireless communications technologies, including cellular and paging, has
increased the market acceptance and awareness of the benefits of two-way radios.
This, in turn, has resulted in the development of many new applications for
these products. In addition, as manufacturers of two-way radios have introduced
lower-priced two-way radio units with additional features and have significantly
expanded the marketing and distribution of these products, they have expanded
their appeal to a larger base of potential users who desire to communicate
within a limited geographic area without incurring airtime or subscriber
charges. Finally, as the result of abuse in their day-to-day usage, two-way
radios have a significant replacement demand. As the number of site-based radios
has increased, replacement demand has increased accordingly.
 
     The manufacturing of two-way radios is dominated by a small number of
companies including Motorola, Kenwood, Icom, Yaesu, Maxon, EF Johnson and
Standard each of which has developed a network of authorized dealers to augment
their internal direct sales forces. Over the past ten years, manufacturers have
strategically reduced the size of their direct sales forces, increasingly
relying on independent authorized dealers. The Company believes that an
increasing percentage of two-way radio products will continue to be sold through
independent dealers as manufacturers continue to outsource distribution and
other non-core functions. The Company believes that its worldwide distribution
capability enhances its relationships with suppliers which seek to support
fewer, but larger, dealer organizations and allows it to more effectively
compete for certain customers that have multiple locations around the country.
 
                                       30
<PAGE>   32
 
     The Company believes that Motorola has manufactured a majority of the
two-way radios currently in use in the world. For many years Motorola sold
virtually all its two-way products through a direct sales force and a small
number of full-line dealers. In calendar 1987, Motorola introduced its Radius
line of products to expand its share of the growing market for lower priced
two-way radio products. To market, sell and service these products, Motorola
developed an indirect distribution channel made up of hundreds of local dealers
across the United States, as well as export dealers that serve the rest of the
world. As the quality and size of the indirect distribution channel expanded,
Motorola substantially reduced the size of its direct sales force. Motorola
continues to have a sizable direct sales force which generally focuses on large
scale projects requiring a high level of engineering and significant investment
in equipment and infrastructure. Management estimates that approximately half of
Motorola's sales of site-based radios and equipment are made through its direct
sales force with the remainder being sold through dealers. The Company is the
largest independent distributor of Motorola two-way radios and believes that
Motorola's utilization of dealers will increase. In addition, the Company
believes that the growth in the number of Motorola's full-line dealers has
slowed significantly in recent years as Motorola has begun to limit the
availability of new dealer agreements in markets with an established group of
dealers.
 
     While manufacturing is highly concentrated, the distribution of two-way
radio products is highly fragmented. Dealers sell two-way radios to business
users principally through field offices and to a lesser extent through catalog
marketing. In any given metropolitan area there are generally several authorized
dealers serving local customers. A typical dealer has one or a few locations
covering a local or regional area and has revenues of under $5 million. In
addition, a small number of mail order companies market two-way radio products.
Like local dealers, these companies tend to be relatively small, with revenues
of less than $5 million. The Company's strategy is to capitalize on the
combination of its leadership position in both the field office and catalog
marketing channels and the highly fragmented nature of the two-way radio
distribution business by acquiring local dealerships and otherwise increasing
its market share in the two-way radio market. To the Company's knowledge, no
other distributor of two-way radios has a significant presence in each of the
Company's distribution channels.
 
     Other segments of the wireless communications industry include specialized
mobile radio, enhanced specialized mobile radio, satellite-based wireless
communications, paging, cellular telephone, PCS and wireless data products. The
Company believes that these segments of the wireless communication industry will
experience significant growth in the future. While the principal focus of the
Company historically has been on the sale and rental of two-way radios, the
Company's strategy is to increase its market share in these segments as and if
its channels of distribution allow it to efficiently distribute these products
to customers. In addition, the Company intends to capitalize on its position as
a leading distributor of products manufactured by Nextel Communications, Inc.
("Nextel"). See "-- Products and Services."
 
BUSINESS STRENGTHS
 
     The Company believes that the following factors have been of principal
importance in the success that it has achieved to date:
 
  MARKET LEADERSHIP IN MULTIPLE DISTRIBUTION CHANNELS
 
          Wireless International is the largest independent distributor of
     two-way radios in the world, with leading positions in each of the field
     office, catalog marketing and export channels. The Company believes that it
     is the only significant distributor of two-way radios leveraging the
     strengths of these multiple channels of distribution. The Company believes
     that the combined strength of these channels provides it with broader
     access to its market than most of its competitors.
 
          Field Offices. The Company believes that field offices are essential
     to developing and maintaining customer relationships in local markets. The
     Company currently operates 34 field offices in the United States and two in
     Australia. These field offices employ approximately 170 sales and rental
     representatives who establish local customer relationships by providing
     on-site evaluation and technical assistance in selecting appropriate
     equipment for specific applications. Field sales representatives target
     local opportu-
 
                                       31
<PAGE>   33
 
     nities to both sell or rent the Company's products. The Company provides
     most administrative, order fulfillment and repair functions on a
     centralized basis to enhance the productivity of its field sales
     representatives by providing them with more time to focus on revenue
     generating activities.
 
          Catalog Operations. The Company markets directly to its existing and
     prospective domestic customers through frequent targeted mailings of
     product catalogs, brochures and other direct marketing pieces. In its 1997
     fiscal year, the Company mailed over 4.4 million direct marketing pieces.
     BearCom uses proprietary information systems to analyze the results of each
     mailing and to refine and segment its customer database and mailing lists.
     In addition, the Company has developed internal catalog production and
     mailing capabilities that facilitate flexible production runs and rapid
     cycle times. These capabilities enable the Company to target future
     mailings in a manner designed to enhance profitability and customer
     response.
 
          Export Operations. The Company markets internationally through Condor
     from its Miami, Florida office, as well as offices in Caracas, Venezuela
     and Prague, Czech Republic. Condor's customer base consists of dealers in
     over 75 countries, concentrated in Latin America, Eastern Europe, Africa
     and the Middle East. Since its founding in 1980, Condor has become the
     largest exporter of two-way radios from the United States.
 
  RENTAL MARKET EXPERTISE
 
          In the United States, the Company also rents two-way radios for use at
     sporting events, fairs, parades, conventions and other events, as well as
     in disaster recovery projects, motion picture productions and other
     projects. With a fleet of over 15,000 two-way radios for rent, BearCom
     believes it is the largest renter of two-way radios in the United States.
     In June 1997, the Company acquired a majority of the assets of Motorola's
     Radio Products Group rentals business, including certain inventory, its
     customer list and its toll-free telephone number. The Company generally
     achieves higher profit margins from rental units than from sales of
     comparable two-way radios. In addition, the Company believes that the
     rental market stimulates follow-on purchases of equipment as rental
     customers discover the value to their business of the various uses of these
     products. See "-- Customers."
 
  BREADTH OF PRODUCTS AND CUSTOMER SERVICES
 
          The Company attempts to satisfy its customers' two-way radio needs by
     offering products with a wide range of features from multiple manufacturers
     and a fall range of technical support and repair capabilities. In its 1997
     fiscal year, the Company sold over 100 different models of two-way radios
     that were manufactured by more than ten different companies. These products
     span a wide array of functionality and price points. Unlike many of its
     smaller competitors, the Company maintains a substantial inventory of
     products to allow prompt order fulfillment in most cases. Prior to shipment
     to end users, the Company typically programs and adjusts frequencies in
     order to provide compatibility among the components of the customer's
     two-way system. The Company's service technicians test units prior to
     shipment and thus are able to discover and reduce product malfunctions
     before shipment. Nevertheless, most orders are processed and shipped on the
     same day they are received. The Company's service technicians also provide
     repair services for virtually all of the products the Company sells and in
     most cases perform repairs in less than 48 hours of receipt of the
     equipment. The Company's rapid order fulfillment and repair service
     capability differentiates it from many of its competitors. See "-- Products
     and Services."
 
  ECONOMIES OF SCALE, OPERATIONAL EFFICIENCIES
 
          As the largest independent distributor of two-way radio products, the
     Company believes that it enjoys numerous advantages over its smaller
     competitors. The Company performs most of its administrative and
     distribution activities for its domestic activities at its headquarters
     facility in Dallas and, for its export activities, in Miami. These
     activities include purchasing, credit and collections, catalog production,
     order entry and fulfillment, and management information systems development
     and operations. The
 
                                       32
<PAGE>   34
 
     Company spreads these costs over a greater volume of business than its
     smaller local and regional competitors and believes that in many cases it
     provides its customers with more consistent and higher levels of service.
     Finally, the Company believes that its global distribution capability
     enhances its relationships with suppliers which seek to support fewer, but
     larger, dealer organizations and allows it to more effectively compete for
     certain customers that have multiple locations.
 
GROWTH STRATEGY
 
     The Company's objective is to increase its market share in both the field
sales, catalog marketing and exporting of two-way radios and related products
and be the leading independent distributor in each market it serves. The
Company's strategy is to further develop its global network of field offices by
opening and acquiring field offices in new markets, expand and enhance its
catalog operations, leverage these complementary distribution channels by
broadening its product and service offerings, and support its operations by
providing consistent administrative, distribution, customer service and
technical support functions on a centralized basis. The key elements of its
strategy are as follows:
 
  ACQUIRE AND OPEN OFFICES IN NEW MARKETS
 
          The Company seeks to continue to develop a global network of field
     offices to provide the local service that is essential to developing and
     maintaining customer relationships. Currently, the Company has 34 field
     offices, 29 of which are located in the 50 largest metropolitan statistical
     areas in the United States. The Company intends to pursue opportunities to
     add field offices in additional top 100 metropolitan statistical areas in
     the United States. In addition, the Company currently has two field offices
     in Australia and one each in Venezuela and Czech Republic, and may
     selectively pursue expansion into other international markets. The Company
     plans to enter new markets primarily by acquiring existing operations of
     local and regional dealers, but also by opening new field offices. From
     fiscal 1993 to fiscal 1997, the Company grew primarily as a result of
     internal growth and the opening of nine new sales offices. Since August
     1996, the Company has accelerated its growth through the acquisition of the
     operations of 12 independent dealers, a majority of the assets of
     Motorola's Radio Products Group rentals business and substantially all of
     the assets of Condor. The Company believes that industry fundamentals and
     outsourcing trends by manufacturers will lead to a consolidation of
     independent dealers, and that its position as the largest independent
     dealer will allow it to continue to acquire local authorized dealers and
     expand its national presence. In pursuing acquisitions, the Company
     typically seeks to gain immediate access to the acquired dealer's customer
     base, while consolidating its order fulfillment operations into existing
     facilities.
 
  EXPAND AND ENHANCE CATALOG OPERATIONS
 
          Management believes that its catalog operations represent an efficient
     and complementary distribution channel to its growing network of field
     offices. During fiscal 1997, BearCom mailed over 4.4 million catalogs and
     marketing pieces and processed over 300,000 inbound calls. BearCom uses
     proprietary software to analyze the results of each mailing and enhance
     customer response. In addition, BearCom has developed internal catalog
     production and mailing capabilities that facilitate flexible production
     runs and rapid cycle times. BearCom has made significant investments to
     establish its leading position in the catalog marketing of two-way radios
     and believes that its existing catalog operations can support higher sales
     volumes without incurring significantly higher fixed costs.
 
  EXPAND PRODUCT AND SERVICE OFFERINGS
 
          The Company strives to expand its product offering to include
     complementary products and services that meet the needs of its customers.
     In addition to its broad offering of two-way radios, the Company currently
     sells closed circuit television systems ("CCTV"), aviation transceivers,
     Orbacom console systems, and products and services based on other wireless
     technologies, such as Nextel handsets and services, PageMart pagers and
     services, and Motorola messaging systems. The Company began selling Nextel
     equipment and service in fiscal 1998 and believes it has become a leading
     independent activator of
                                       33
<PAGE>   35
 
     this service. In January 1998, the Company entered into a three year
     agreement with Iridium U.S., L.P. ("Iridium") to nationally market its
     satellite-based communications products and services in selected sales
     channels beginning in fiscal 1999. The Company intends to continue to
     broaden its product offering and may also explore acquiring companies with
     complementary product lines that the Company believes could be efficiently
     distributed to its customers.
 
  EXPAND RENTAL AND REPAIR ACTIVITIES
 
          The Company believes that its ability to offer responsive two-way
     radio rental and repair services enhances its customer relationships. The
     Company currently maintains a rental fleet of over 15,000 two-way radios
     and staffs each office with employees dedicated to local rental
     opportunities. In addition, the Company repairs two-way radios from all of
     its significant suppliers. Most repair services are performed in the
     Company's Dallas and Houston facilities and are typically completed within
     48 hours of receipt. Revenues from rental and repair activities have
     increased as a percentage of total revenues from approximately 13.0% in
     fiscal 1995 to 18.6% for the nine months ended January 31, 1998. The
     Company generally achieves higher profit margins from these activities than
     from the sale of its products. To date, most rentals have been to customers
     in the United States. The Company intends to expand its rental and repair
     activities in international markets.
 
  INCREASE PENETRATION IN EXISTING MARKETS
 
          The Company believes that there are significant opportunities to
     further penetrate existing markets. By centralizing administrative,
     fulfillment and other support functions and by encouraging customers to
     order replacement parts and other routine items directly through the
     Company's toll-free number, management seeks to enhance the productivity of
     its field sales force by providing them with time to focus on more
     significant revenue-generating activities. In addition, the Company uses
     its catalog database to identify quality sales leads that could benefit
     from higher-end or more sophisticated systems. Finally, as certain of its
     existing markets mature, the Company intends to add sales representatives
     and/or acquire other dealers in existing markets to gain new customers and
     better service existing accounts.
 
PRODUCTS AND SERVICES
 
     The Company believes that its ability to offer a broad line of products and
services is instrumental to its success. The Company seeks to offer products
with a wide range of features and price points from multiple manufacturers,
along with a full range of technical support and repair services. In its 1997
fiscal year, the Company sold over 100 different models of two-way radios that
were manufactured by more than ten different companies. The Company also sells
other wireless communication products, including two-way radio accessories,
pagers and accessories, cellular phone accessories and aviation transceivers, as
well as related products like CCTV and Orbacom console systems. In fiscal 1997,
equipment sales accounted for 83% of the Company's revenues.
 
     On September 1, 1997, the Company began marketing wireless equipment and
services of Nextel, and believes that it has become one of the largest
independent activators of such services. Under its marketing agreement, the
Company sells Nextel handsets at the Company's cost and receives an activation
fee for each handset sold, as well as a percentage of the monthly service charge
per handset for a defined period. The terms and fees of the agreement can be
altered without the consent of the Company.
 
     On January 26, 1998, the Company entered into an agreement with Iridium to
become a dealer of Iridium handsets and service within the land mobile radio
market in the United States. Iridium has publicly announced September 1998 as
its anticipated date for commencing service. However, there can be no assurance
as to the eventual timing and impact of this agreement on the Company's
operating results.

     BearCom rents two-way radios and other wireless communication products,
primarily through its field offices. In fiscal 1997, rentals accounted for
approximately 12% of the Company's revenues. The Company maintains a fleet of
over 15,000 rental units, which are used in connection with sporting events,
conventions, disaster recovery projects, motion picture productions and other
events where wireless communication equipment is needed for a period of time
that would not justify the cost of purchasing such products. The rental market
for wireless communication products is seasonal, with rental demand being
greatest during the summer months, or at other peak times of the year in warm
weather climates. The Company believes that the rental market stimulates sales
of these products as rental customers discover the value to their businesses of
the various uses of these products.
 
     The Company repairs two-way radios of leading manufacturers. In fiscal
1997, repair revenue accounted for approximately 4% of the Company's revenues.
In October 1997, the Company acquired a dealer in Houston, Texas which is an
authorized service provider of Motorola two-way radios, including warranty and
non-warranty repair services. In the case of units under warranty, the Company
collects predetermined repair fees directly from the manufacturer. For
non-warranty repairs, the Company bills the customer for repair charges. Such
repair charges are billed on a time and materials basis or, in certain
instances, on a flat rate schedule agreed to in advance. The Company typically
completes and ships repaired units within 48 hours of their receipt. The
Company's primary service and repair operations are located at its facilities in
Dallas and Houston, with limited repairs being performed at 14 of the Company's
field offices. The Company's technicians repair products sold both by the
Company and by others. The Company believes that its ability to repair products
is important to its customers.
 
PURCHASING
 
     The Company purchases its products directly from manufacturers of wireless
communication products. Brand names sold by the Company include, among others,
Motorola, Maxon, Icom, Tekk and Orbacom.
 
                                       35

Equipment revenues generated by the sale of products purchased from the
Company's two largest vendors, Motorola and Maxon, constituted approximately 73%
and 12%, respectively, of the Company's revenues during fiscal 1997, and 67% and
8%, respectively, of the Company's equipment revenues during the nine-month
period ended January 31, 1998. As is customary in the industry, the Company does
not have long-term contracts with any of its vendors, including Motorola and
Maxon. Although the Company and its suppliers enter into written vendor
agreements to effect purchases, such agreements generally can be canceled by
either party at will. Termination of the Company's relationship with Motorola or
any other significant manufacturers would have a material adverse effect on the
Company. See "Risk Factors -- Dependence on Vendors."
 
CUSTOMERS
 
     BearCom's customers range from small businesses to large organizations and
governmental agencies, while Condor's customers generally are dealers, which in
turn sell to similar end users. In fiscal 1997, BearCom sold products to
approximately 80% of the Fortune 100 companies and Condor sold products to
dealers in approximately 75 countries. In fiscal 1997, over 80% of the Company's
revenues were from repeat customers. No customer of the Company accounted for
more than 2% of the Company's revenues in fiscal 1997. Set forth below are
selected customers that have purchased or rented products from the Company since
the beginning of fiscal 1997.

SALES AND MARKETING
 
     Overview. Wireless International markets its products and services through
both its field offices, catalog operations and export operations. The Company
believes that the combined strength of these channels provides it with broader
access to its market than most of its competitors. The Company also rents
two-way radios and other wireless communication products. Through its
approximately 170 person field sales and rental force, the Company services
customers requiring on-site evaluation of their needs and provides the technical
assistance to help them select the appropriate equipment for their specific
applications. For customers not requiring this consultative approach (usually
when system needs are relatively uncomplicated or purchases are add-on or
replacement units to an existing system), the catalog marketing channel provides
customers an efficient and cost-effective method of purchasing products.
 
     The Company attempts to use the combination of its distribution channels to
attract new customers and stimulate additional purchases by previous customers.
The Company seeks to attract new customers by expanding the reach of its sales
representatives, selectively mailing catalogs to prospective customers,
advertising in the Yellow Pages and trade publications, and exhibiting at
industry trade shows. The Company seeks to stimulate purchases by previous
customers by both personal contact and direct mail. The Company provides product
and sales training to its field sales, rentals, catalog marketing and export
sales forces in an effort to employ a knowledgeable workforce.
 
     Field Offices. The Company currently maintains 34 field offices in the
United States and two in Australia, primarily in major metropolitan areas.
Typically, the Company's field office staff is comprised of a branch manager,
three to seven sales representatives and a rental coordinator. Sales
representatives are compensated by salary as well as commission and incentive
bonuses based on predetermined sales quotas. BearCom emphasizes
"need-satisfaction selling," training its sales representatives to identify the
specific communications needs of the customer and to sell products that will
satisfy those needs. The Company encourages its field sales customers to utilize
the Company's toll-free number to purchase replacement parts and other routine
items so that sales representatives may devote their efforts to selling products
to new customers and more sophisticated products to existing customers. The
Company monitors and adjusts its field sales compensation plan periodically to
insure its competitiveness and continuously seeks to improve its support
functions so that field sales representatives can maximize the results of their
marketing efforts.
 
     BearCom also maintains a dedicated rental representative at each field
office. The Company has a fleet of over 15,000 rental units throughout the
United States to satisfy its customers' short-term two-way radio needs. The
Company maintains a constant inventory of rental units at each of its sales
offices to meet its customers' immediate rental needs. The remainder of the
Company's rental fleet is maintained at the Company's Dallas headquarters
facilities. Because the Company has sales offices throughout the United States,
the Company is able to efficiently transfer rental units among its sales offices
in order to meet anticipated rental demand. Prior to a rental order being
filled, the Company programs and tests each unit and ensures that it is equipped
with a fresh battery. For large rental orders, the Company provides on-site
technical personnel. The Company maintains a 24-hour emergency telephone number
for use by all rental customers to remedy operational problems if they occur.
All rental units are checked and serviced upon return to the Company prior to
being returned to the rental inventory.
 
     Catalog Marketing. BearCom also markets its products through the direct
mailing of catalogs, brochures and other direct marketing pieces. The Company
mailed over 4.4 million catalogs and brochures during fiscal 1997 and received
over 300,000 inbound calls, resulting in sales to customers in all 50 states.
BearCom augments its own proprietary mailing lists by selectively renting and
purchasing third-party mailing lists from time to time. BearCom uses proprietary
information systems to refine and segment its customer database and mailing
lists. These procedures enable the Company to target future mailings in a manner
designed to enhance profitability and customer response.
 
     BearCom produces its own catalogs and marketing brochures through its art
department, using desktop publishing systems. These catalogs and brochures are
printed by a small number of national printers and shipped to the Company's
Dallas facility. BearCom has its own mail production department. The mail
production process is managed by BearCom's IBM AS-400 computer so that the mail
is processed to take
                                       37
<PAGE>   39
 
advantage of the lowest postal rates available. See "-- Management Information
System." By having its own mail facility, BearCom has the capability to process
runs as small as a few thousand pieces or as large as several million pieces
with rapid cycle times and still maintain a cost-effective direct marketing
program.
 
     The Company employs catalog sales representatives who staff the Company's
toll-free telephone line, process orders and answer technical questions from
7:30 a.m. to 6:30 p.m. Central Time. The catalog operations rely almost
exclusively on inbound sales. While processing orders, sales representatives
have access, through BearCom's management information system, to technical
information, alternate and complementary product selections, product
availability and pricing information and customer purchasing and credit
histories. The sales representatives are experienced in the sale of wireless
communication products, are knowledgeable of the Company's products and strive
to assist customers in fulfilling their wireless communication needs.
 
     Export Operations. The Company markets internationally through Condor from
its Miami, Florida office, as well as offices in Caracas, Venezuela and Prague,
Czech Republic. Condor's customer base consists of dealers in over 75 countries,
concentrated in Latin America, Eastern Europe, Africa and the Middle East. Since
its founding in 1980, Condor has become the largest exporter of two-way radios
from the United States.
 
OPERATIONS
 
     Order Fulfillment. The Company keeps a sufficient inventory of products
available in its Dallas headquarters and Miami facilities so that, it typically
can ship orders directly to customers on the same day the order is received.
Once a purchase order is accepted by the Company and the products are retrieved
from inventory, the products normally require some technical service before
being delivered to the customer. For example, radio frequencies may need to be
coordinated or ancillary equipment may need to be added to a system. All
products are tested prior to shipment. After testing, BearCom's delivery
department packs the products and ships them to the customer via United Parcel
Service, Federal Express or other common carriers from BearCom's distribution
facility in Dallas. During fiscal 1997, the Company shipped an average of over
15,000 transactions per month. With respect to sales by Condor, products
generally are drop-shipped by the manufacturer directly to customers in Eastern
Europe, while customers in Latin American generally take title to products at
Condor's Miami facility.
 
     Inventory Management. The Company believes that effective purchasing and
inventory control are key elements to its ability to fill customer orders. The
Company maintains an inventory management system which analyzes historical sales
results, sales projections and information regarding vendor lead times in order
to determine appropriate inventory levels. Historically, the Company has not
written-down significant portions of its inventories due to shrinkage or
obsolescence, nor has it relied on its ability to return slow-moving inventory
to the vendor. There can be no assurance that material write-downs of the
Company's inventory will not occur in the future. See "Risk
Factors -- Technological Change."
 
     Credit and Collection Management; Product Returns. BearCom attempts to
minimize losses on credit sales by closely monitoring its customers'
creditworthiness, using both internal credit histories as well as CD-ROM and
on-line services from Dun & Bradstreet. Collection activities are conducted by
using outbound phone calls from the Company's Dallas and Miami facilities.
BearCom's bad debt expense as a percentage of total revenues for fiscal 1996,
fiscal 1997 and the nine-month period ended January 31, 1998 was 0.3%, 0.5% and
1.1%, respectively. Condor's bad debt expense as a percentage of total revenues
for calender 1995, 1996 and 1997 was 1.89%, 1.39% and 0.25%, respectively.
Condor's follows the industry practice of allowing customers to return products
within 30 days, so long as the products have not been damaged.
 
MANAGEMENT INFORMATION SYSTEM
 
     The use of BearCom's IBM AS-400 computer system is pervasive in the
operation of its business. The Company has invested substantial resources to
develop proprietary software applications enabling BearCom to compile and
maintain its marketing database, track customer repair histories, manage its
inventory, maintain its accounting records and track credit and collection
activities. BearCom believes that these applications enable it to deliver
superior customer service and achieve cost savings. Each of BearCom's sales
offices has a continuous on-line connection to BearCom's computer system to
support the sales efforts of its field sales
                                       38

representatives. Condor utilizes a PC-based management information system. The
Company has no immediate plans to integrate this system with BearCom's. The
Company has adopted procedures to protect its computer systems and to provide
for recovery in the event of equipment failure. All system data is backed up to
tape daily with backup tapes stored off-site.
 
COMPETITION
 
     The two-way radio distribution industry is highly competitive and is
currently comprised of several regional and numerous local dealers. The
principal bases of competition in the industry are price and service. The sale
of two-way radios is a low-margin, high-volume business. Because awareness of
two-way wireless communication products is growing and the cost barriers to
entry into this market are relatively low, the risk of new competitors entering
this market is high. The Company believes that the industry will become more
competitive as the number of competitors increases and as new technologies
emerge. These factors, coupled with the growing industry emphasis on containing
costs, could place significant pressure on the Company to reduce prices, which
could significantly reduce the gross margins realized by the Company on sales of
its products.
 
     In addition, several manufacturers of two-way radio products, including
Motorola, also compete with independent distributors in selling, servicing and
renting two-way wireless communication products. There can be no assurance that
manufacturers of two-way radio products will continue to utilize independent
distributors in the future. In addition, there are several significantly large
global distributors of wireless communication products other than two-way
radios. These companies to date have not entered the two-way radio distribution
market in any significant way, but there can be no assurance that these
companies will not enter this industry in the future. These manufacturers and
distributors are much larger than the Company, and have substantially greater
capital resources, sales experience and distribution capabilities than the
Company. In response to competitive pressure from any of its current or future
competitors, the Company may be required to lower selling prices, which would
lower the Company's gross margins, which could have a material adverse effect on
the Company. See "Risk Factors -- Competition."
 
EMPLOYEES
 
     As of April 1, 1998, BearCom had 467 employees, of whom 51 were corporate
employees, 172 were sales or rental managers or sales or rental representatives,
45 were shipping and distribution personnel, 25 were catalog distribution
employees, 104 were service technicians and 70 were in various other positions.
As of April 1, 1998, Condor employed 60 employees in various capacities. The
Company's success is dependent on its ability to attract and retain good
employees. The Company believes that its employee relations are good. The
Company's employees are not covered by any collective bargaining agreements.
 
PROPERTIES
 
     The Company leases its approximately 37,000 square foot headquarters
facility (which includes its warehousing facility, product distribution center
and a field office) and its approximately 10,000 square foot mail distribution
center, each of which is located in Dallas, Texas. The terms of these leases
expire in January 1999 and the Company has options to extend each lease for an
additional one year period. In addition, the Company leases 35 locations as
field offices and owns one sales office in Houston, Texas. As a result of the
Condor Acquisition, the Company owns its approximately 15,000 square foot Miami,
Florida office and distribution facility, as well as its offices in Caracas,
Venezuela and Prague, Czech Republic. See "Management -- Certain Transactions."
 
LEGAL MATTERS
 
     From time to time, the Company is involved in lawsuits that it considers to
be in the normal course of its business, which have not resulted in any material
losses to date.

    Company's 401(k) Plan.
 
STOCK OPTION PLAN
 
     Pursuant to the Wireless International Inc. 1998 Stock Option Plan (the
"Stock Option Plan"), options may be granted to eligible employees of the
Company or its subsidiaries and directors of the Company for the purchase of an
aggregate of           shares of Common Stock of the Company. Employees eligible
under the Stock Option Plan are those employees whose performance and
responsibilities are determined by the Board or a committee selected by the
Board in accordance with the terms of the Stock Option Plan (the "Committee") to
be influential to the Company's success. The Stock Option Plan is administered
by the Board or the Committee which determines, in its discretion, the terms of
each option in accordance with the provisions of the Stock Option Plan,
including the number of shares subject to each option granted, the related
exercise price, the vesting period and vesting conditions, and option period.
The Board or the Committee may grant either nonqualified stock options or
incentive stock options ("ISOs"), as defined by the Code; provided, however,
that ISOs may be granted only to employees.
 
     The Stock Option Plan requires that the exercise price of each option that
is intended to constitute an ISO must not be less than 100% of the fair market
value of the Common Stock at the time of the grant of the option. The option
period may not be more than ten years from the date the option is granted. No
ISO, however, may be granted to an employee who owns more than 10% of the total
combined voting power of all classes of outstanding stock of the Company or its
subsidiaries unless the option price is at least 110% of the fair market value
of the Common Stock at the date of the grant and the option period does not
exceed five years. Options may be exercised in annual installments as specified
by the Board or the Committee, and all installments that become exercisable are
cumulative and may be exercised at any time after they become exercisable until
expiration of the option. Options are not assignable except by will or by the
laws of descent and distribution.
 
     There is no limit on the fair market value of options that may be granted
to an employee in any calendar year, but no employee may be granted ISOs that
first become exercisable during a calendar year for the purchase of stock with
an aggregate fair market value (determined as of the date of grant of each
option) in excess of $100,000. An ISO (or an installment thereof) counts against
the annual limitations only in the year it first becomes exercisable.
 
     Full payment for shares purchased upon exercise of an option must be made
at the time of exercise, and no shares may be issued until full payment is made.
The Stock Option Plan provides that an option agreement may include a provision
permitting an optionee the right to tender previously owned shares of Common
Stock in partial or full payment for shares to be purchased on exercise of an
option. Unless sooner terminated by action of the Board, the Stock Option Plan
will terminate in             , 2008 and no options may thereafter be granted
under the Stock Option Plan. The Stock Option Plan may be discontinued, altered
or amended in certain respects by the Board without the approval of the
shareholders. However, the Stock Option Plan may not be amended without the
approval of the shareholders (i) to materially increase benefits, (ii) to
materially increase the number of shares of Common Stock that may be issued
under the Stock Option Plan, or (iii) to materially modify the requirements for
participation in the Stock Option Plan.

     As of           1998, options to purchase           shares had been granted
at the Offering price to certain directors, key employees and officers of the
Company.
 
EXCULPATORY CHARTER PROVISION; LIABILITY AND INDEMNIFICATION OF OFFICERS AND
DIRECTORS
 
     Texas law permits Texas corporations to include in their articles of
incorporation a provision eliminating or limiting director liability to a
corporation or its shareholders for monetary damages arising from acts or
omissions in the director's capacity as a director. The only limitations imposed
under the statute are that the provision may not eliminate or limit a director's
liability to the extent the director is found liable for (a) a breach of the
director's duty of loyalty to the corporation or its shareholders, (b) an act or
omission not in good faith that constitutes a breach of duty of the director to
the corporation or an act or omission that involves intentional misconduct or a
knowing violation of the law, (c) a transaction from which the director received
an improper benefit, whether or not the benefit resulted from an action taken
within the scope of the director's office, or (d) an act or omission for which
the liability of a director is expressly provided by an applicable statute. The
Company's Restated Articles of Incorporation contain a provision eliminating the
liability of the Company's directors to the fullest extent permitted by Texas
statutory or decisional law, as the same exists or as it may be amended or
interpreted from time to time.
 
     In addition, the Company's Amended and Restated Bylaws require it to
indemnify its directors and officers against any and all liability and
reasonable expense that may be incurred by them in connection with or resulting
from (a) any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative, arbitrative or investigative, (b) an
appeal on such an action, suit or proceeding, or (c) an inquiry or investigation
that could lead to such an action, suit or proceeding, all to the fullest extent
permitted by Texas law.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     During the Company's last completed fiscal year, the Board did not have a
compensation committee or other committee performing equivalent functions. As a
result, during the Company's last completed fiscal year, the entire Board was
responsible for establishing executive officer compensation.
 
CERTAIN TRANSACTIONS
 
     On December 1, 1995, the Company lent to John P. Watson, the Chairman of
the Board of the Company, $933,300, the proceeds of which Mr. Watson used to
exercise a stock option that the Company had granted in April 1992. The loan is
evidenced by a promissory note bearing interest at 7%. In addition, during
fiscal years 1993, 1995 and 1996, the Company made cash advances to Mr. Watson
aggregating $452,200. These advances are evidenced by four separate promissory
notes, each bearing interest at 7%. The greatest aggregate amount of principal
and interest outstanding under these five promissory notes during fiscal years
1995, 1996 and 1997 was $449,896, $1,492,596 and $1,589,581, respectively.
Amounts outstanding under all five notes are secured by           shares of
Common Stock held by Mr. Watson. At January 31, 1998, the aggregate amount of
principal and interest outstanding under these five promissory notes was
approximately $1,662,320. Mr. Watson has indicated that he intends to repay all
amounts outstanding under these five promissory notes with the proceeds from the
sale of shares of Common Stock to be sold by him in the Offering.
 
     On April 28, 1995, the Company sold land and a building to Gary Weber, Vice
President of the Company, in exchange for a note receivable of $325,000 bearing
interest at 9%. The note and accrued interest are due on April 28, 2000 and are
secured by a first lien on the property. At that time, the Company agreed to
reduce the outstanding balance of the note, and related accrued interest, by 20%
per year as long as Mr. Weber stays in the employment of the Company. As a
result, the note receivable and related interest are being charged to
compensation expense over a five-year period.
 
     The Company rents its Costa Mesa, California, office from a partnership
controlled by Jerry Denham, Kenneth H. Doll and Brent A. Bisnar, executive
officers of the Company. Total rental payments to this partnership were
$104,777, $112,816 and $94,740 for the years ended April 30, 1995, 1996 and
1997,

respectively. Bear Communications guaranteed payment of two promissory notes
that are secured by this property and were issued in connection with the
partnership's purchase of this property. It is anticipated that this partnership
will pay all amounts outstanding under these notes with the proceeds from shares
of Common Stock to be sold in the Offering by certain partners.

                          DESCRIPTION OF CAPITAL STOCK
 
     The Company has authorized capital stock consisting of           shares of
Common Stock, $0.01 par value, and 1,000,000 shares of preferred stock, $0.01
par value. At December 31, 1997, there were           shares of Common Stock
outstanding, owned by 21 holders of record, and there were no shares of
preferred stock outstanding. A total of          shares of Common Stock are
reserved for future issuance under, and for issuance upon the exercise of
options granted or which may be granted under, the Stock Option Plan. See
"Management -- Stock Option Plan."
 
COMMON STOCK
 
     The rights of the holder of each share of Common Stock are identical in all
respects. All outstanding shares of Common Stock are, and the shares of Common
Stock offered hereby when issued and paid for will be validly issued, fully paid
and nonassessable. All holders of Common Stock have full voting rights and are
entitled to one vote for each share held of record on all matters submitted to a
vote of the shareholders. Votes may not be cumulated in the election of
directors. Shareholders have no preemptive or subscription rights. The Common
Stock is neither redeemable nor convertible, and there are no sinking fund
provisions. Holders of Common Stock are entitled to dividends when, as and if
declared by the Board of Directors from funds legally available therefor and are
entitled, upon liquidation, to share ratably in all assets remaining after
payment of liabilities. The rights of holders of Common Stock will be subject to
any preferential rights of any preferred stock which may be issued in the
future.
 
PREFERRED STOCK
 
     The Board of Directors of the Company is authorized (without any further
action by the shareholders) to issue preferred stock in one or more series and
to fix the voting rights, liquidation preferences, dividend rates, conversion
rights, redemption rights and terms, including sinking fund provisions, and
certain other rights and preferences. Satisfaction of any dividend preferences
of outstanding preferred stock would reduce the amount of funds available for
the payment of dividends on Common Stock. Also, holders of preferred stock would
normally be entitled to receive a preference payment in the event of any
liquidation, dissolution or winding-up of the Company before any payment is made
to the holders of Common Stock. In addition, under certain circumstances, the
issuance of preferred stock may render more difficult or tend to discourage a
merger, tender offer or proxy contest, the assumption of control by a holder of
a large block of the Company's securities or the removal of incumbent
management. The Board of Directors of the Company, without shareholder approval,
may issue preferred stock with voting and conversion rights which could
adversely affect the holders of Common Stock. The Company has no present
intention to issue any shares of preferred stock.
 
SPECIAL PROVISIONS OF THE AMENDED AND RESTATED ARTICLES OF INCORPORATION AND
AMENDED AND RESTATED BYLAWS
 
     The provisions of the Company's Amended and Restated Articles of
Incorporation and Amended and Restated Bylaws summarized in the succeeding
paragraphs may be deemed to have an anti-takeover effect and may delay, defer or
prevent a tender offer or takeover attempt that a shareholder might consider in
such shareholder's best interest, including attempts that might result in a
premium over the market price for the shares held by shareholders.
 
     Pursuant to the Company's Amended and Restated Articles of Incorporation,
the Company's Board of Directors by resolution may establish one or more series
of preferred stock having such number of shares, designations, relative voting
rights, dividend rates, liquidation and other rights, preferences and
limitations as may be fixed by the Board of Directors without any further
shareholder approval. Such rights, preferences, powers and limitations as may be
established could have the effect of impending or discouraging the acquisition
of control of the Company.
 
     The Company's Amended and Restated Bylaws provides that (a) the Board of
Directors is divided into three classes that are elected for staggered
three-year terms; (b) shareholders may only remove a director for cause, and
only by the affirmative vote of holders of not less than two-thirds of the
outstanding voting stock of
                                       45
<PAGE>   47
 
the Company; and (c) meetings of shareholders can be called only by the Chairman
of the Board, President, a majority of the Board of Directors or holders of not
less than 25% of the shares entitled to vote at such meeting. To be amended,
these provisions require the affirmative vote of a majority of the Board of
Directors or the holders of not less than two-thirds of the outstanding voting
stock of the Company.
 
REGISTRATION RIGHTS
 
     The Company has granted to all of its shareholders the right to register
shares of Common Stock owned by them in connection with the registration by the
Company of shares of Common Stock. The Company would bear the expenses of
registration of any such shareholder. See "Risk Factors -- Shares Eligible for
Future Sale; Registration Rights."
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this offering, the current shareholders of the Company
will own approximately   % of the outstanding Common Stock (     % if the
Underwriters' over-allotment option is exercised in full). Officers, directors
and certain shareholders of the Company, who will own     % of the outstanding
shares following this offering (     % if the Underwriters' over-allotment
option is exercised in full), have agreed with the Underwriters not to sell,
grant any option to sell, transfer or otherwise dispose of, directly or
indirectly, any shares of Common Stock (other than those being sold pursuant to
this offering) for a period of 180 days following the date of this Prospectus
without the prior written consent of the Representatives. See "Underwriting."
 
     Upon completion of this offering, the Company will have     shares of
Common Stock outstanding (          shares if the Underwriters' over-allotment
option is exercised in full). Of these shares, the           shares sold in this
offering (          shares if the Underwriters' over-allotment option is
exercised in full) will be freely tradeable in the public market without
restriction by persons other than affiliates of the Company. All of the
remaining shares are "restricted securities" within the meaning of Rule 144
under the Securities Act. Approximately           shares held for more than one
year may be sold 90 days after the Company has been subject to the reporting
requirements of Section 13 of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), subject to the volume, manner of sale and other
limitations of Rule 144. Following the expiration or release from the 180-day
lock-up agreements with the representatives of the Underwriters, approximately
          additional shares of Common Stock will be eligible for sale in
accordance with the requirements of Rule 144, subject to compliance with certain
volume limitations. See "Underwriting."
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are required to be aggregated) who has beneficially owned, for at
least one year, shares of Common Stock that have not been registered under the
Securities Act or that were acquired from an "affiliate" of the Company, is
entitled to sell within any three month period a number of shares of Common
Stock that does not exceed the greater of 1% of the then-outstanding shares of
Common Stock (     shares upon completion of this offering) and the average
weekly reported trading volume in the Common Stock during the four calendar
weeks preceding such sale. Sales under Rule 144 also are subject to certain
notice and manner-of-sale requirements and the availability of current public
information about the Company. A person (or persons whose shares are aggregated)
who is not an affiliate of the Company (in general, a person who is not a
director, officer or principal shareholder of the Company) during the three
months prior to resale and who has beneficially owned such shares for at least
two years is entitled to sell such restricted stock under Rule 144 without
regard to the requirements discussed above, other than the manner-of-sale
provisions.
 
     The Company is unable to estimate the number of shares that may be sold in
the future by its shareholders since this will depend on the market price for
the Common Stock, the personal circumstances of
 
                                       46
<PAGE>   48
 
the shareholders and other factors. Any sale of substantial amounts of shares in
the open market may significantly reduce the market price of the Common Stock
offered hereby.
 
     Subject to certain limitations on the aggregate offering price of a
transaction and other conditions, Rule 701 under the Securities Act may be
relied upon with respect to the resale of shares of Common Stock originally
purchased from the Company by its employees, directors and officers prior to the
date the Company becomes subject to the reporting requirements of the Exchange
Act pursuant to written compensatory benefit plans or written contracts relating
to the compensation of such persons. Shares of Common Stock issued in reliance
on Rule 701 are "restricted shares" and, beginning 90 days after the Company
becomes subject to the reporting requirements of the Exchange Act, may be sold
by persons other than affiliates, subject to the provisions regarding
manner-of-sale under Rule 144, and by affiliates under Rule 144 without
compliance with its one-year minimum holding period requirements.
 
     The Company intends to file a registration statement on Form S-8 under the
Securities Act to register all of the shares of Common Stock issued or reserved
for future issuance under the Stock Option Plan. After the effective date of
that registration statement, shares purchased upon exercise of options granted
pursuant to the Plan will be available for resale in the public market without
restriction by persons who are not affiliates of the Company, and to the extent
they are held by affiliates, pursuant to Rule 144, without observance of the
holding period requirements. As of          , 1998, there were options
outstanding to purchase a total of        shares of Common Stock, of which
options to purchase           shares are presently exercisable.

     The Company and the Selling Shareholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments that the Underwriters may be
required to make in respect thereof.
 
     The Representatives have advised the Company that the Underwriters propose
initially to offer the shares of Common Stock in part directly to the public at
the initial public offering price set forth on the cover page of this Prospectus
and in part to certain dealers (including the Underwriters) at such price less a
concession not in excess of $          per share. The Underwriters may allow,
and such dealers may reallow, to certain other dealers a concession not in
excess of $          per share. After the initial offering of the Common Stock,
the public offering price and other selling terms may be changed by the
Representatives at any time without notice. The Underwriters do not intend to
confirm sales to any accounts over which they exercise discretionary authority.
 
     The Company has granted an option to the Underwriters, exercisable within
30 days after the date of this Prospectus, to purchase, from time to time, in
whole or in part, up to an aggregate of      additional shares of Common Stock
at the initial public offering price, less underwriting discounts and
commissions. The Underwriters may exercise such option solely to cover
overallotments, if any, made in connection with the Offering. To the extent that
the Underwriters exercise such option, each Underwriter will become obligated,
subject to certain conditions, to purchase its pro rata share of such additional
shares based on such Underwriter's percentage underwriting commitment as
indicated in the preceding table.
 
     Each of the Company, its executive officers and directors and certain
shareholders of the Company (including the Selling Shareholders) has agreed,
subject to certain exceptions, not to (i) offer, pledge, sell, contract to sell,
sell any option or contract to purchase, purchase any option or contract to
sell, grant any option, right or warrant to purchase or otherwise transfer or
dispose of, directly or indirectly, any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock or (ii) enter
into any swap or other arrangement that transfers all or a portion of the
economic consequences associated with the ownership of any Common Stock
(regardless of whether any of the transactions described in clause (i) or (ii)
is to be settled by the delivery of Common Stock, or such other securities, in
cash or otherwise) for a period of 180 days after the date of this Prospectus
without the prior written consent of DLJ. In addition, during such period, the
Company has also agreed not to file any registration statement with respect to,
and each of its executive officers, directors and certain shareholders of the
Company (including the Selling Shareholders) has agreed not to make any demand
for, or exercise any right with respect to, the registration of any shares of
Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock without DLJ's prior written consent.
 
     Prior to the Offering, there has been no established trading market for the
Common Stock. The initial public offering price for the shares offered hereby
will be determined by negotiation among the Company representatives of the
Selling Shareholders and the Representatives. The factors to be considered in

prospects for the industry in which the Company competes, the past and present
operations of the Company, the historical results of operations of the Company,
the prospects for future earnings of the Company, the recent market prices of
securities of generally comparable companies and the general condition of the
securities markets at the time of the Offering.
 
     Application has been made for the Common Stock to be approved for quotation

for that purpose is required. The shares of Common Stock offered hereby may not
be offered or sold, directly or indirectly, nor may this Prospectus or any other
offering material or advertisements in connection with the offer and sale of any

     In connection with the Offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Common Stock. Specifically, the Underwriters may overallot the Offering,
creating a syndicate short position. The Underwriters may bid for and purchase
shares of Common Stock in the open market to cover such syndicate short position
or to stabilize the price of the Common Stock. In addition, the underwriting
syndicate may reclaim selling concessions from syndicate members and selected
dealers if they repurchase previously distributed Common Stock in syndicate

activities may stabilize or maintain the market price of the Common Stock above

The Board of Directors and Stockholders
Wireless International, Inc.:
 
     We have audited the consolidated financial statements of Wireless
International, Inc. and subsidiaries as listed in the accompanying index. In
connection with our audits of the consolidated financial statements, we also
have audited the financial statement schedule as listed in the accompanying
index. These consolidated financial statements and financial statement schedule
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these consolidated financial statements and financial
statement schedule 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 Wireless
International, Inc. and subsidiaries as of April 30, 1996 and 1997 and January
31, 1998, and the results of their operations and their cash flows for each of
the years in the three-year period ended April 30, 1997 and the nine months
ended January 31, 1998, in conformity with generally accepted accounting
principles.

                 WIRELESS INTERNATIONAL, INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
               APRIL 30, 1995, 1996 AND 1997 AND JANUARY 31, 1998
 
(1) GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  (a) General
 
     Wireless International, Inc. (formerly BearCom, Inc.), and subsidiaries
(the "Company"), is the surviving company resulting from the merger of Page-Com,
Inc. ("Page-Com") and Bear Communications, Inc. ("Bear Communications") on
December 27, 1995 (see note 2). The Company is principally in the business of
selling and renting site-based two-way radios, pagers and other wireless
communication equipment to customers throughout the United States, as well as a
number of foreign countries.
 
     The consolidated financial statements include Wireless International, Inc.
and its subsidiaries. All significant intercompany accounts and transactions
have been eliminated in consolidation.
 
  (b) Inventory
 
     Inventory consists primarily of two-way radios and accessories and is
stated at the lower of average cost or market. Inventory is stated net of
reserves for obsolete items of $279,978 and $196,413 at April 30, 1996 and 1997,
respectively, and $374,565 at January 31, 1998.
 
  (c) Fixed Assets
 
     Fixed assets are stated at cost. Depreciation is provided using the
straight-line method over the estimated useful lives of the related assets,
which range from 3 to 7 years for equipment and fixtures and 20 years for the
building. Rental equipment is depreciated over five years. Leasehold
improvements are amortized on a straight-line basis over the shorter of their
useful life or the related lease term. Renewals and improvements that
significantly add to the productive capacity or extend the useful life of an
asset are capitalized. Repairs and maintenance are charged to expense as
incurred.
 
  (d) Costs in Excess of Tangible Net Assets Acquired
 
     Costs in excess of tangible net assets acquired are being amortized using
the straight-line method over an estimated useful life of thirty years. The
Company assesses the recoverability of costs in excess of tangible net assets
acquired by determining whether the amortization of the balance over its
remaining life can be recovered through undiscounted future operating cash flows
of the acquired operation. The amount of impairment, if any, is measured based
on projected discounted future operating cash flows using a discount rate
reflecting the Company's average cost of funds. The assessment of recoverability
will be impacted if estimated future operating cash flows are not achieved.
Costs in excess of tangible net assets acquired are stated net of accumulated
amortization of $65,840 and $98,889 at April 30, 1996 and 1997, respectively,
and $271,538 at January 31, 1998.
 
  (e) Revenue
 
     The Company records revenue from product sales at the time the related
products are shipped. Sales are recorded net of returns and allowances. Rental
income is recognized when earned.
 
  (f) Advertising Costs
 
     The Company expenses the costs of advertising as incurred, except for
direct-response advertising and catalog costs which are capitalized and
amortized over their expected period of future benefit (generally one year).
Direct-response advertising costs consist primarily of the cost of mailing lists
and printing, postage and contract services related to catalogs used to market
the Company's products. Total advertising costs reported as assets included in
"prepaid expenses and other" were $706,926 and $1,413,898 at April 30, 1996
 
                                       F-7

and 1997, respectively, and $1,295,453 at January 31, 1998. Advertising expense
was $1,668,599, $1,654,995 and $1,459,592 for the years ended April 30, 1995,
1996 and 1997, respectively, and $1,568,036 for the nine months ended January
31, 1998.
 
  (g) Foreign Currency Translation
 
     Financial statements of the Company's Australian subsidiary are translated
into U.S. dollars using the exchange rate at each balance sheet date for assets
and liabilities and the average exchange rate for each period for revenues,
expenses and gains and losses. Translation adjustments are reflected as a
component of stockholders' equity. Gains or losses from foreign currency
transactions are included in net income.
 
  (h) Income Taxes
 
     Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date.
 
     For periods prior to January 1, 1995, Bear Communications was subject to
taxation under Subchapter S of the Internal Revenue Code for federal income tax
purposes. Accordingly, no provision was made for federal income taxes as the
liability for such taxes was the responsibility of the stockholders of Bear
Communications. Effective January 1, 1995, Bear Communications terminated its
Subchapter S election. In connection with this change, Bear Communications also
changed its method of accounting for income tax purposes from the cash basis to
the accrual basis. For periods subsequent to January 1, 1995, income taxes have
been provided for Bear Communications using the provisions of Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" (Statement
109) and are included in the consolidated financial statements. The effect of
initial implementation of Statement 109 for Bear Communications at January 1,
1995 due to the change in tax status was a charge to income tax expense of
$693,225.
 
     The unaudited pro forma income tax data included in the consolidated
statement of income for the year ended April 30, 1995 has been determined after
computing federal income taxes as if Bear Communications had been directly
responsible for federal income taxes for all periods presented using the asset
and liability method of accounting for income taxes as prescribed in Statement
109. In connection with the change in tax status, Bear Communications made
distributions to its shareholders in a tax-free distribution of $422,916
representing previously taxed but undistributed earnings.
 
  (i) Earnings Per Share
 
     Basic earnings per share is computed by dividing net income by the weighted
average number of common shares outstanding. Diluted earnings per share is
computed by dividing net income by the weighted average number of common shares
plus the number of additional shares that would have resulted from potentially
dilutive securities.
 
     The weighted average number of shares outstanding for the years ended April
30, 1995 and 1996 were 9,335.5 and 9,480.3, respectively. The weighted average
number of shares outstanding for the year ended April 30, 1997, and the nine
months ended January 1997 and 1998 were 10,372.5. Potentially dilutive
securities were not considered to be dilutive for the years ended April 30,
1995, 1996 or 1997, or the nine months ended January 31, 1997 and 1998.

  (j) Statement of Cash Flows Information
 
     For purposes of the statement of cash flows, the Company considers all
highly liquid investments with original maturities of three months or less to be
cash equivalents. There were no cash equivalents at April 30, 1996 or 1997 or
January 31, 1998.

     Noncash transactions consist of the sale of land and a building to an
officer of the Company in fiscal 1995 in exchange for a note and the sale of
common stock to an officer of the Company in fiscal 1996 in exchange for a full
recourse note (see note 6).
 
  (k) Use of Management Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  (l) Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of
 
     Long-lived assets are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net cash flows expected
to be generated by the asset. If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceed the fair value of the assets. Assets to be disposed
of are reported at the lower of the carrying amount or fair value less costs to
sell.
 
(2) MERGER
 
     On December 27, 1995, Page-Com issued 6,223.5 shares of its common stock in
exchange for all of the outstanding common stock of Bear Communications in a
transaction accounted for as a pooling-of-interests. Accordingly, the
consolidated financial statements for periods prior to the combination have been
restated to combine the accounts and results of operations of Page-Com and Bear
Communications. There were no significant transactions between Page-Com and Bear
Communications prior to the combination.

(6) RELATED PARTY TRANSACTIONS
 
     The Company has notes and interest receivable from a shareholder/officer
related to cash advances of $559,296 and $656,281 at April 30, 1996 and 1997,
respectively, and $729,020 at January 31, 1998. The notes bear interest at 7%
with all unpaid interest and principal due in May 1999. The notes are secured by
222 shares of the Company's common stock. In a separate transaction, this
officer exercised options in December 1995 to acquire 1,037 shares of Page-Com's
common stock at a price of $900 per share. The options were granted in April
1992. The exercise of the options was funded by a full recourse loan from the
Company of $933,300 bearing interest at 7% and due in April 1999. The Company
has no other options outstanding.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     On April 28, 1995, the Company sold land and a building to an employee who
was the former owner of Page-Com in exchange for a note receivable of $325,000
bearing interest at 9%. The note and accrued interest are due on April 28, 2000
and are secured by a first lien on the property. The Company recognized a loss
on disposal of the property of approximately $180,000 which is included in the
consolidated statement of income for the year ended April 30, 1995. The Company
has agreed to reduce the outstanding balance of the note, and related accrued
interest, by 20% per year as long as this employee stays in the employment of
the Company. As a result, the note receivable and related interest are being
charged to compensation expense over a five-year period. Compensation expense of
$94,250 was recognized pursuant to this transaction for each of the years ended
April 30, 1996 and 1997 and $70,688 for the nine months ended January 31, 1998.
 
     The Company rents its Costa Mesa, California office from an affiliated
partnership pursuant to a verbal arrangement. Total rent paid to the partnership
was $104,777, $112,816 and $94,740 for the years ended April 30, 1995, 1996 and
1997, respectively and $71,055 for the nine months ended January 31, 1998.
 
     At April 30, 1995, Bear had outstanding advances to officers of $167,000
which were repaid in the year ended April 30, 1996. At April 30, 1997, the
Company had outstanding advances to a shareholder/officer of $33,000 (none at
January 31, 1998).
 
(7) NOTE PAYABLE TO BANK
 
     The Company had a short-term line of credit with a bank for borrowings of
up to $9,000,000 at April 30, 1996. Borrowings were secured by substantially all
the assets of the Company. The line of credit was due on October 2, 1996, and
amended on November 1, 1996. The amendment, in addition to other changes,
extended the due date of the note, resulting in a reclassification of borrowings
under the line of credit from short-term to long-term (see note 8).
 
(8) LONG-TERM DEBT
 
     Long-term debt at April 30, 1996 and 1997 and January 31, 1998 consists of

     The Company has a credit agreement with a bank (the "Senior Bank
Facility"), as amended on August 29, 1997, which provides for borrowings of up
to $20,000,000 in the form of a $15,000,000 working capital line of credit
("revolving line of credit") and a $5,000,000 acquisition line of credit. The
revolving line of credit bears interest at either an adjusted LIBOR rate (5.6%
at January 31, 1998) plus 1.25% or at the bank's prime rate (8.5% at January 31,
1998). At the request of the Company, the bank may issue letters of
 
                                      F-12

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
credit to the Company's vendors for the acquisition of inventory. The aggregate
outstanding amount of any letters of credit constitute a portion of the
revolving line of credit and shall not exceed $2,000,000. The revolving line of
credit is due on November 5, 1999. The agreement was amended on March 27, 1998
to increase the amount available under the revolving line of credit to
$25,000,000. The actual amount available to the Company on a daily basis under
its revolving line of credit is based on the "free cash flow" of the Company as
defined by the agreement. Borrowings under the Senior Credit Facility are
secured by substantially all the assets of the Company.
 
     The acquisition line of credit bears interest at either an adjusted LIBOR
rate plus 1.35% or at the bank's prime rate. The acquisition line of credit
converted to a term note on November 5, 1997, at which time the Company became
required to repay the amount of all principal outstanding in equal monthly
installments through November 5, 2001.
 
     The Senior Bank Facility agreement restricts the Company's ability to issue
or redeem capital stock, incur additional debt and pay dividends. It also
requires the Company to maintain certain financial ratios. At January 31, 1998,
the Company was not in compliance with one of the financial covenants. In the
March 27, 1998 amendment, the bank waived the requirement to meet certain
financial covenants through May 31, 1998 and agreed to reset those covenants as
a result of the Condor acquisition (see note 13). The fair market value of the
note payable to bank is estimated to approximate the related book value based on
current market rates.
 
(9) LEASES
 
     The Company leases certain of its operating facilities and equipment under
both capital and operating leases. At January 31, 1998, minimum rental payments

     No valuation allowances were considered necessary at April 30, 1996 or 1997
or January 31, 1998 as management believes it is more likely than not that the
existing deductible temporary differences will be offset by future reversals of
differences generating taxable income.
 
(11) BUSINESS AND CREDIT CONCENTRATIONS
 
     The Company's customers are located primarily throughout the United States.
The Company had no customers who accounted for more than 10% of consolidated
sales in 1995, 1996 or 1997 or for the nine months ended January 31, 1998.
 
     Substantially all of the Company's sales are made on credit. The Company
evaluates credit risks on an individual basis before extending credit to its
customers, and it believes the allowance for doubtful accounts adequately
provides for loss or uncollectible accounts.
 
(12) EMPLOYEE BENEFITS PLAN
 
     The Company maintains a 401(k) profit sharing plan for substantially all
employees. Effective February 1, 1996, the Company matches 75% of employee
contributions up to 5% of their compensation. Prior to February 1, 1996,
Page-Com matched 100% and Bear Communications matched 50% of employee
contributions up to 5% of their compensation. Company contributions of $152,630,
$198,599 and $240,977 for the years ended April 30, 1995, 1996 and 1997,
respectively, and $220,214 for the nine months ended January 31, 1998 were
charged to expense.
 
(13) SUBSEQUENT EVENT
 
     In March 1998, the Company entered into a transaction to purchase certain
assets of three related entities which sell communication equipment. The
purchase price of $7,000,000 was financed through borrowings under the long-term
debt arrangement. The agreement also requires additional consideration of
$3,000,000 to be paid over the next two years should the income of the acquired
entities reach certain targets. The acquisition will be accounted for using the
purchase method of accounting. Accordingly, the purchase price will be allocated
to the net assets acquired based on their estimated fair values.

NOTE 3: INVESTMENT IN SUBSIDIARY
 
     In 1996, a joint venture called Condor Telecommunications, C.A. was formed
in which Condor Communications, Ltd. has a 50% equity interest. The Group
accounts for this investment on the equity method. The Group's income from this
subsidiary was not material for the years ended December 31, 1996 and 1997.
 
NOTE 4: LINE OF CREDIT
 
     The Company has a revolving line of credit facility in the amount of
$2,000,000 which was unused at December 31, 1996 and 1997. Bank advances on the
credit line carry a variable interest rate of 1.00% over the base rate of the
bank. The credit line is collateralized by substantially all corporate assets,
and is personally guaranteed by the Company's Stockholders.
 
NOTE 5: INCOME TAXES
 
     Condor Communications, Inc., the principal operating company within the
group, has elected to be taxed under the Internal Revenue Code to be an S
Corporation. In lieu of corporate income taxes, the shareholders of an S
Corporation are taxed on their proportionate share of the Company's taxable
income. Accordingly, provisions for income taxes have not been made on its
earnings. The affiliated companies in the Group serve as distribution channels
and either do not have material net earnings over the three-year period ended
December 31, 1997 or operate out of a tax haven with no corporate income taxes.
As a consequence, no provision for income taxes has been made in the combined
financial statements.

NOTE 6: BUSINESS & CREDIT CONCENTRATIONS
 
     The Company purchases substantially all of its inventory from Motorola Inc.
and is economically dependent on that vendor for favorable trade terms as well
as products for sale.
 
     The Company transacts most of its business with customers located in Latin
American and Eastern Europe. Accordingly, the Company's business may be affected
by political and economic changes in the region.

Item 14. Indemnification of Directors and Officers.

     As permitted by the Texas Business Corporation Act, the Registrant's
Restated Articles of Incorporation and Amended and Restated Bylaws provide that
the directors and officers of the Registrant shall be indemnified by the
Registrant against certain liabilities that those persons may incur in their
capacities as directors or officers. Furthermore, the Registrant's Articles of
Incorporation eliminate the liability of directors of the Registrant to the
maximum extent permitted by the Texas Business Corporation Act. See 
"Management -- Exculpatory Charter Provision; Liability and Indemnification of
Officers and Directors" in the Prospectus.

     The Underwriting Agreement to be filed as Exhibit 1.1 hereto contains
reciprocal agreements of indemnity between the Registrant and the underwriters
as to certain liabilities, including liabilities under the Securities Act of
1933, as amended (the "Securities Act"), and in certain circumstances provides
for indemnification of the Registrant's directors and officers.

Item 15. Recent Sales of Unregistered Securities.

     During the previous three years, the Registrant has issued and sold the
following securities (all such amounts having been adjusted to reflect the
_____-for-1 stock split effected in _____, 1998) without registration under the
Securities Act (none of which sales were underwritten):

     In connection with the Merger, in December 1995 the Company issued an
aggregate of ___________ shares of Common Stock to shareholders of Bear
Communications. The Registrant believes that these transactions were exempt from
the registration requirements of the Securities Act pursuant to Section 4(2)
thereof.

     In December 1995, Mr. Watson exercised options to acquire ______  shares of
Common Stock at an exercise price of approximately _____ per share. The options
were granted in April 1992. The exercise of such options was funded by a full
recourse loan from the Company to Mr. Watson in the amount of $933,000, bearing
interest at 7% and is due in April 1999. The Registrant believes that this
transaction was exempt from the registration requirements of the Securities Act
pursuant to Section 4(2) thereof.

Item 17. Undertakings.

   
(a) Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. If a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

   
(b) The undersigned Registrant hereby undertakes to provide to the
representatives of the underwriters at the closing specified in the Underwriting
Agreement certificates in such denominations and registered in such names as
required by the representatives of the underwriters to permit prompt delivery to
each purchaser.

(c) The undersigned Registrant hereby undertakes that:

    (1) For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.

    (2) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement relating to the securities offered therein,
and this offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

                                    OFFICES

       Section 1.    Principal Office.  The principal office of the Corporation
shall be in Dallas County, Texas, or such other county as the Board of
Directors may from time to time designate.

       Section 2.    Other Offices.  The Corporation may also have offices at
such other places both within and without the State of Texas as the Board of
Directors may from time to time determine or the business of the Corporation
may require.

                                   ARTICLE II

                                  SHAREHOLDERS

       Section 1.    Time and Place of Meetings.  Meetings of the shareholders
shall be held at such time and at such place, within or without the State of
Texas, as shall be determined by the Board of Directors.

       Section 2      Annual Meetings.  Annual meetings of shareholders shall
be held on such date and at such time as shall be determined by the Board of
Directors.  At each annual meeting the shareholders shall elect a Board of
Directors and transact such other business as may properly be brought before
the meeting.

       Section 3.    Special Meetings.  Special meetings of the shareholders
may be called at any time by the Chairman of the Board, the President or the
Board of Directors, and shall be called by the Chairman of the Board, the
President or the Secretary at the request in writing of the holders of not less
than ten percent (10%) of the voting power represented by all the shares
issued, outstanding and entitled to be voted at the proposed special meeting,
unless the Articles of Incorporation provide for a different percentage, in
which event such provision of the Articles of Incorporation shall govern.  Such
request shall state the purpose or purposes of the proposed meeting.  Business
transacted at special meetings shall be confined to the purposes stated in the
notice of the meeting.

       Section 4.    Notice.  Written or printed notice stating the place, day
and hour of any shareholders, meeting and, in the case of a special meeting,
the purpose or purposes for which the meeting is called, shall be delivered not
less than ten nor more than 60 days before the date of the meeting, either
personally or by mail, by or at the direction of the Chairman of the Board,
President, Secretary or the officer or person calling the meeting, to each
shareholder entitled to vote at such meeting.  If mailed, such notice shall be
deemed to be delivered when deposited in the United States mail, postage
prepaid, addressed to the shareholder at his address as it appears on the share
transfer records of the Corporation.

       Section 5.    Closing of Share Transfer Records and Fixing Record Dates
for Matters Other than Consents to Action.  For the purpose of determining
shareholders entitled to notice of or to vote at any meeting of shareholders or
any adjournment thereof, or entitled to receive payment of any distribution or
share dividend, or in order to make a determination of shareholders for any
other proper purpose (other than determining shareholders entitled to consent
to action by shareholders proposed to be taken without a meeting of
shareholders) , the Board of Directors of the Corporation may provide that the
share transfer records shall be closed for a stated period but not to exceed,
in any case, 60 days.  If the share transfer records shall be closed for the
purpose of determining shareholders, such records shall be closed for at least
ten days immediately preceding such meeting.  In lieu of closing the share
transfer records, the Board of Directors may fix in advance a date as the
record date for any such determination of shareholders, such date in any case
to be not more than





                                       1
<PAGE>   5
60 days and, in the case of a meeting of shareholders, not less than ten days
prior to the date on which the particular action requiring such determination
of shareholders is to be taken.  If the share transfer records are not closed
and no record date is fixed for the determination of shareholders entitled to
notice of or to vote at a meeting of shareholders, or shareholders entitled to
receive payment of a distribution (other than a distribution involving a
purchase or redemption by the Corporation of any of its own shares) or share
dividend, the date on which notice of the meeting is mailed or the date on
which the resolution of the Board of Directors declaring such distribution or
share dividend is adopted, as the case may be, shall be the record date for
such determination of shareholders.  When a determination of shareholders
entitled to vote at any meeting of shareholders has been made as provided in
this section, such determination shall apply to any adjournment thereof except
where the determination has been made through the closing of share transfer
records and the stated period of closing has expired.

       Section 6.    Fixing Record Dates for Consents to Action.  Unless a
record date shall have previously been fixed or determined pursuant to this
Section 6, whenever action by shareholders is proposed to be taken by consent
in writing without a meeting of shareholders, the Board of Directors may fix a
record date for the purpose of determining shareholders entitled to consent to
that action, which record date shall not precede, and shall not be more than
ten days after, the date upon which the resolution fixing the record date is
adopted by the Board of Directors.  If no record date has been fixed by the
Board of Directors and the prior action of the Board of Directors is not
required by the Texas Business Corporation Act (herein called the "Act"), the
record date for determining shareholders entitled to consent to action in
writing without a meeting. shall be the first date on which a signed written
consent setting forth the action taken or proposed to be taken is delivered to
the Corporation as provided in Section 10 of this Article II.  Delivery shall
be by hand or by certified or registered mail, return receipt requested.
Delivery to the Corporation's principal place of business shall be addressed to
the President or the Chairman of the Board of the Corporation.  If no record
date shall have been fixed by the Board of Directors and prior action of the
Board of Directors is required by the Act, the record date for determining
shareholders entitled to consent to action in writing without a meeting shall
be at the close of business on the date on which the Board of Directors adopts
a resolution taking such prior action.

       Section 7.    List of Shareholders.  The officer or agent of the
Corporation having charge of the share transfer records for shares of the
Corporation shall make, at least ten days before each meeting of the
shareholders, a complete list of the shareholders entitled to vote at such
meeting or any adjournment thereof, arranged in alphabetical order, with the
address of and the number of voting shares held by each, which list, for a
period of ten days prior to such meeting, shall be kept on file at the
registered office or principal place of business of the Corporation and shall
be subject to inspection by any shareholder at any time during the usual
business hours of the Corporation.  Such list shall also be produced and kept
open at the time and place of the meeting and shall be subject to the
inspection of any shareholder during the whole time of the meeting.  The
original share transfer records shall be prima facie evidence as to who are the
shareholders entitled to examine such list or transfer records or to vote at
any meeting of shareholders.  Failure to comply with the requirements of this
Section 7 shall not affect the validity of any action taken at such meeting.

       Section 8.    Quorum.  With respect to any matter, a quorum shall be
present at a meeting of shareholders if the holders of shares having a majority
of the voting power represented by all issued and outstanding shares entitled
to vote on that matter are present in person or represented by proxy, unless
otherwise provided by the Articles of Incorporation in accordance with the Act.
Once a quorum is present at a meeting of shareholders, the shareholders
represented in person or by proxy at the meeting may conduct such business as
may properly be brought before the meeting until it is adjourned, and the
subsequent withdrawal from the meeting of any shareholder or the refusal of any
shareholder represented in person or by proxy to vote shall not affect the
presence of a quorum at the meeting.  If, however, a quorum shall not be
present at any





                                       2
<PAGE>   6
meeting of shareholders, the shareholders entitled to vote, present in person
or represented by proxy, shall have power to adjourn the meeting, without
notice (other than announcement at the meeting at which the adjournment is
taken of the time and place of the adjourned meeting), until such time and to
such place as may be determined by a vote of the holders of a majority of the
shares represented in person or by proxy at such meeting until a quorum shall
be present.  At such adjourned meeting at which a quorum is present, any
business may be transacted which might have been transacted at the meeting as
originally noticed.

       Section 9.    Voting.  When a quorum is present at any meeting, the vote
of the holders of a majority of the shares entitled to vote on a matter,
present in person or represented by proxy at such meeting, shall decide such
matter brought before such meeting, other than the election of directors or a
matter for which the affirmative vote of the holders of a specified portion of
the shares entitled to vote is required by the Act, and shall be the act of the
shareholders, unless otherwise provided by the Articles of Incorporation or
these Bylaws in accordance with the Act.

       Unless otherwise provided in the Articles of Incorporation or these
Bylaws in accordance with the Act, directors of the Corporation shall be
elected by a plurality of the votes cast by the holders of shares entitled to
vote in the election of directors at a meeting of shareholders at which a
quorum is present.

       At every meeting of the shareholders, each shareholder shall be entitled
to such number of votes, in person or by proxy, for each share having voting
power held by such shareholder, as is specified in the Articles of
Incorporation (including the resolution of the Board of Directors (or a
committee thereof) creating such shares), except to the extent that the voting
rights of the shares of any class or series are limited or denied by the
Articles of Incorporation.  At each election of directors, every shareholder
shall be entitled (a) to cast, in person or by proxy, the number of votes to
which the shares owned by him are entitled for as many persons as there are
directors to be elected and for whose election he has a right to vote or (b)
unless prohibited by the Articles of Incorporation and subject to the
immediately succeeding sentence of this paragraph, to cumulate the votes to
which the shares owned by him are entitled by giving one candidate as many
votes as the number of such directors multiplied by the shares owned by him
shall equal or by distributing such votes on the same principle among any
number of such candidates.  Cumulative voting shall not be allowed in an
election of directors unless a shareholder who intends to cumulate his votes
shall have given written notice of such intention to the Secretary of the
Corporation on or before the day preceding the election at which such
shareholder intends to cumulate his votes; all shareholders entitled to vote
cumulatively may cumulate their votes if any shareholder gives such written
notice.  Every proxy shall be in writing and be executed by the shareholder.  A
telegram, telex, cablegram, or similar transmission by the shareholder, or a
photographic, photostatic, facsimile, or similar reproduction of a writing
executed by the shareholder, shall be treated as an execution in writing for
the purposes of this Section 9. No proxy shall be valid after 11 months from
the date of its execution unless otherwise provided therein.  Each proxy shall
be revocable unless (i) the proxy form conspicuously states that the proxy is
irrevocable, and (ii) the proxy is coupled with an interest, as defined in the
Act and other Texas law.

       Shares standing in the name of another corporation may be voted by such
officer, agent or proxy as the bylaws of such corporation may prescribe or, in
the absence of such provision, as the board of directors of such corporation
may determine.

       Shares held by an administrator, executor, guardian or conservator may
be voted by him, either in person or by proxy, without a transfer of such
shares into his name.  Shares standing in the name of a trustee may be voted by
him, either in person or by proxy, but no trustee shall be entitled to vote
shares held by him without a transfer of such shares into his name as trustee.

       Shares standing in the name of a receiver may be voted by such receiver,
and shares held by or under the control of a receiver may be voted by such
receiver without being transferred into his name, if such authority is
contained in an appropriate order of the court that appointed the receiver.

       A shareholder whose shares are pledged shall be entitled to vote such
shares until the shares have been transferred into the name of the pledgee, and
thereafter the pledgee shall be entitled to vote the shares so transferred.

       Treasury shares, shares of the Corporation's stock owned by another
corporation the majority of the voting stock of which is owned or controlled by
the Corporation, and shares of its own stock held by the Corporation in a
fiduciary capacity shall not be voted, directly or indirectly, at any meeting,
and shall not be counted in determining the total number of outstanding shares
at any given time.

       Section 10.   Action by Consent.  Any action required or permitted to be
taken at a meeting of the shareholders may be taken without a meeting, without
prior notice, and without a vote if a consent in writing, setting forth the
action so taken, shall be signed by all of the shareholders entitled to vote
with respect to the action that is the subject of the consent.

       In addition, if the Articles of Incorporation so provide, any action
required or permitted to be taken at a meeting of the shareholders 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
holder or holders of shares having not less than the minimum number of votes
that would be necessary to take such action at a meeting at which the holders
of all shares entitled to vote on the action were present and voted.  Prompt
notice of the taking of any action by shareholders without a meeting by less
than unanimous written consent shall be given to those shareholders who did not
consent in writing to the action.

       Every written consent signed by the holders of less than all the shares
entitled to vote with respect to the action that is the subject of the consent
shall bear the date of signature of each shareholder who signs the consent.  No
written consent signed by the holders of less than all the shares entitled to
vote with respect to the action that is the subject of the consent shall be
effective to take the action that is the subject of the consent unless, within
60 days after the date of the earliest dated consent delivered to the
Corporation as set forth below in this Section 10, the consent or consents
signed by the holder or holders of shares having not less than the minimum
number of votes that would be necessary to take the action that is the subject
of the consent are delivered to the Corporation by delivery to its registered
office, registered agent, principal place of business, transfer agent,
registrar, exchange agent, or an officer or agent of the Corporation having
custody of the records in which proceedings of meetings of shareholders are
recorded.  Delivery shall be by hand or certified or registered mail, return
receipt requested.  Delivery to the Corporation's principal place of business
shall be addressed to the President or the Chairman of the Board of the
Corporation.

       A telegram, telex, cablegram, or similar transmission by a shareholder,
or a photographic, photostatic, facsimile, or similar reproduction of a writing
signed by a shareholder, shall be regarded as signed by the shareholder for the
purposes of this Section 10.

       Section 11.   Presence at Meetings by Means of Communications Equipment.
Shareholders may participate in and hold a meeting of the shareholders by means
of conference telephone or similar communications equipment by means of which
all persons participating in the meeting can hear each other, and participation
in a meeting pursuant to this Section 11 shall constitute presence in person at
such meeting, except where a person participates in the meeting for the express
purpose of objecting to the transaction of any business on the ground that the
meeting is not lawfully called or convened.

                                  ARTICLE III

                                   DIRECTORS

       Section 1.    Powers.  The business and affairs of the Corporation shall
be managed by its Board of Directors, which shall have and may exercise all
powers of the Corporation and take all lawful acts as are not by the Act, the
Articles of Incorporation or these Bylaws directed or required to be exercised
or taken by the shareholders.

       Section 2.    Number, Election and Terms of Directors; Board Action.
The number of directors shall be fixed from time to time exclusively by the
Board of Directors pursuant to a resolution adopted by a majority of the total
number of directors.  Commencing with the first shareholders, meeting after
adoption of these Restated Bylaws at which directors are elected, the directors
shall be divided, with respect to the time for which they severally hold
office, into three classes, as nearly equal in number as reasonably possible,
with the term of office of the first class to expire at the first annual
meeting of shareholders after their election, the term of office of the second
class to expire at the second annual meeting of shareholders after their
election, and the term of office of the third class to expire at the third
annual meeting of shareholders after their election, with each director to hold
office until his or her successor is duly elected and qualified.  At each
annual meeting of shareholders after the first shareholders' meeting after
adoption of these Restated Bylaws, (i) directors elected to succeed those
directors whose terms then expire shall be elected for a term of office to
expire at the third succeeding annual meeting of shareholders after their
election, with each director to hold office until his or her successor is duly
elected and qualified and (ii) if authorized by a resolution of the Board of
Directors, directors may be elected to fill any vacancy on the Board of
Directors, regardless of how such vacancy shall have been created.

       Section 3.    Resignations.  Any director may resign at any time by
giving written notice of his resignation to the Corporation, effective at the
time specified therein or, if not specified, immediately upon its receipt by
the Corporation.  Unless otherwise specified in the notice, acceptance of a
resignation shall not be necessary to make it effective.

       Section 4.    Vacancies.  Subject to other provisions of this Section 4,
any vacancy occurring in the Board of Directors may be filled by election at an
annual or special meeting of the shareholders called for that purpose or by the
affirmative vote of a majority of the remaining directors, though the remaining
directors may constitute less than a quorum of the Board of Directors as fixed
by Section 10 of this Article III.  A director elected to fill a vacancy shall
be elected for the unexpired term of his predecessor in office.  Any
directorship to be filled by reason of an increase in the number of directors
shall be filled by election at an annual meeting or at a special meeting of
shareholders called for that purpose or may be filled by the Board of Directors
for a term of office continuing only until the next election of one or more
directors by the shareholders; provided that the Board of Directors may not f
ill more than two such directorships during the period between any two
successive annual meetings of shareholders.

       Any director may be removed, with cause, at any time, by the affirmative
vote by written ballot of two-thirds of the voting interest of the shareholders
of record of the Corporation entitled to vote, given at an annual meeting or at
a special meeting of the shareholders called for that purpose.

       Notwithstanding the foregoing, whenever the holders of any class or
series of shares or group of classes or series of shares are entitled to elect
one or more directors by the provisions of the Articles of Incorporation, only
the holders of shares of that class or series or group shall be entitled to
vote for or against the removal of any director elected by the holders of
shares of that class or series or group; and any vacancies in such





                                       5
<PAGE>   9
directorships and any newly created directorships of such class or series or
group to be filled by reason of an increase in the number of such directors may
be filled by the affirmative vote of a majority of the directors elected by
such class or series or group then in office or by a sole remaining director so
elected, or by the vote of the holders of the outstanding shares of such class
or series or group, and such directorships shall not in any case be filled by
the vote of the remaining directors or the holders of the outstanding shares as
a whole unless otherwise provided in the Articles of Incorporation.

       Section 5.    General Powers.  The powers of the Corporation shall be
exercised by or under the authority of, and the business and affairs of the
Corporation shall be managed under the direction of, its Board of Directors,
which may do or cause to be done all such lawful acts and things, as are not by
the Act, the Articles of Incorporation or these Bylaws directed or required to
be exercised or done by the shareholders.

       Section 6.    Place of Meetings.  The Board of Directors of the
Corporation may hold meetings, both regular and special, either within or
without the State of Texas.

       Section 7.    Annual Meetings.  The first meeting of each newly elected
Board of Directors shall be held, without further notice, immediately following
the annual meeting of shareholders at the same place, unless by the majority
vote or unanimous consent of the directors then elected and serving, such time
or place shall be changed.

       Section 8.    Regular Meetings.  Regular meetings of the Board of
Directors may be held with or without notice at such time and place as the
Board of Directors may determine by resolution.

       Section 9.    Special Meetings.  Special meetings of the Board of
Directors may be called by or at the request of the Chairman of the Board or
President and shall be called by the Secretary on the written request of a
majority of the incumbent directors.  The person or persons authorized to call
special meetings of the Board of Directors may fix the place for holding any
special meeting of the Board of Directors called by such person or persons.
Notice of any special meeting shall be given at least 24 hours previous thereto
if given either personally (including written notice delivered personally or
telephone notice) or by telex, telecopy, telegram or other means of immediate
communication, and at least 72 hours previous thereto if given by written notice
mailed or otherwise transmitted to each director at the address of his business
or residence.  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.  Any director may waive notice of
any meeting, as provided in Section 2 of Article IV of these Bylaws.  The
attendance of a director at a meeting shall constitute a waiver of notice of
such meeting, except where a director attends a meeting for the express purpose
of objecting to the transaction of any business on the ground that the meeting
is not lawfully called or convened.

       Section 10.   Quorum and Voting.  At all meetings of the Board of
Directors, the presence of a majority of the number of directors fixed in the
manner provided in Section 2 of this Article III shall constitute a quorum for
the transaction of business, unless a different number or portion is required
by law, the Articles of Incorporation, or these Bylaws.  At all meetings of
committees of the Board of Directors (if one or more be designated in the
manner described in Section 11 of this Article III), the presence of a majority
of the number of directors fixed from time to time by resolution of the Board
of Directors to serve as members of such committees shall constitute a quorum
for the transaction of business.  The affirmative vote of at least a majority
of the directors present and entitled to vote at any meeting of the Board of
Directors or a committee of the Board of Directors at which there is a quorum
shall be the act of the Board of Directors or the committee, except as may be
otherwise specifically provided by the Act, the Articles of Incorporation or
these Bylaws.  Directors may not vote by proxy at any meeting of the Board of
Directors.  Directors with an interest in a





                                       6
<PAGE>   10
business transaction of the Corporation and directors who are directors or
officers or have a financial interest in any other corporation, partnership,
association or other organization with which the Corporation is transacting
business may be counted in determining the presence of a quorum at a meeting of
the Board of Directors or of a committee of the Board of Directors to authorize
such business transaction.  If a quorum shall not be present at any meeting of
the Board of Directors or a committee thereof, a majority of the directors
present thereat may adjourn the meeting, without notice other than announcement
at the meeting, until such time and to such place as may be determined by such
majority of directors, until a quorum shall be present.

       Section 11.   Committees of the Board of Directors.  The Board of
Directors may, by resolution passed by a majority of the whole Board of
Directors, designate from among its members one or more committees, each of
which shall be composed of one or more of its members, and may designate one or
more of its members as alternate members of any committee, who may, subject to
any limitations imposed by the Board of Directors, replace absent or
disqualified members at any meeting of that committee.  Any such committee, to
the extent provided in the resolution of the Board of Directors designating the
committee or in the Articles of Incorporation or these Bylaws, shall have and
may exercise all of the authority of the Board of Directors of the Corporation,
except where action of the Board of Directors is required by the Act or by the
Articles of Incorporation.  Any member of a committee of the Board of Directors
may be removed, for or without cause, by the affirmative vote of a majority of
the whole Board of Directors.  If any vacancy or vacancies occur in a committee
of the Board of Directors caused by death, resignation, retirement,
disqualification, removal from office or otherwise, the vacancy or vacancies
shall be filled by the affirmative vote of a majority of the whole Board of
Directors.  Such committee or committees shall have such name or names as may
be designated by the Board of Directors and shall keep regular minutes of their
proceedings and report the same to the Board of Directors when required.

       Section 12.   Compensation of Directors.  Unless otherwise provided by
resolution of the Board of Directors, directors, as members of the Board of
Directors or of any committee thereof, shall not be entitled to receive any
stated salary for their services.  Nothing herein contained, however, shall be
construed to preclude any director from serving the Corporation in any other
capacity and receiving compensation therefor.

       Section 13.   Action by Unanimous Consent.  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 a written consent, setting
forth the action so taken, is signed by all the members of the Board of
Directors or the committee, as the case may be, and such written consent shall
have the same force and effect as a unanimous vote at a meeting of the Board of
Directors.

       Section 14.   Presence at Meetings by Means of Communications Equipment.
Members of the Board of Directors of the Corporation or any committee
designated by the Board of Directors, may participate in and hold a meeting of
such board or committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation in a meeting pursuant to this
Section 14 shall constitute presence in person at such meeting, except where a
person participates in the meeting for the express purpose of objecting to the
transaction of any business on the ground that the meeting is not lawfully
called or convened.

                                   ARTICLE IV

                                    NOTICES

       Section 1.    Form of Notice.  Whenever under the provisions of the Act,
the Articles of Incorporation or these Bylaws, notice is required to be given
to any director or shareholder, and no provision





                                       7
<PAGE>   11
is made as to how such notice shall be given, it shall not be construed to mean
personal notice exclusively, but any such notice may be given in writing, by
mail, postage prepaid, or by telex, telecopy, or telegram, or other means of
immediate communication, addressed or transmitted to such director or
shareholder at such address as appears on the books of the Corporation.  Any
notice required or permitted to be given by mail shall be deemed to be given at
the time when the same be thus deposited, postage prepaid, in the United States
mail as aforesaid.  Any notice required or permitted to be given by telex,
telecopy, telegram, or other means of immediate communication shall be deemed
to be given at the time of actual delivery.

       Section 2.    Waiver.  Whenever under the provisions of the Act, the
Articles of Incorporation or these Bylaws, any notice is required to be given
to any director or shareholder of the Corporation, a waiver thereof in writing
signed by the person or persons entitled to such notice, whether before or
after the time stated in such notice, shall be equivalent to the giving of such
notice.

       Section 3.    When Notice Unnecessary.  Whenever, under the provisions
of the Act, the Articles of Incorporation or these Bylaws, any notice is
required to be given to any shareholder, such notice need not be given to the
shareholder if:

       (a)    notice of two consecutive annual meetings and all notices of
              meetings held during the period between those annual meetings, if
              any, or

       (b)    all (but in no event less than two) payments (if sent by first
              class mail) of distributions or interest on securities during a
              12-month period,

have been mailed to that person, addressed at his address as shown on the
records of the Corporation, and have been returned undeliverable.  Any action
or meeting taken or held without notice to such a person shall have the same
force and effect as if the notice had been duly given.  If such a person
delivers to the Corporation a written notice setting forth his then current
address, the requirement that notice be given to that person shall be
reinstated.

                                   ARTICLE V

to time.  The officers shall hold office until their successors are chosen and
qualified.  No officer need be a member of the Board of Directors except the
Chairman of the Board, if one be elected.  Any officer elected or appointed by
the Board of Directors may be removed, with or without cause, at any time by a
majority vote of the whole Board.  Election or appointment of an officer or
agent shall not of itself create contract rights.

       Section 3.    Chairman of the Board.  The Chairman of the Board, if any,
shall preside, when present, at all meetings of shareholders and at all
meetings of the Board of Directors, shall have such powers





                                       8

shall perform the duties of the President, and when so acting, shall have all
the powers of and be subject to all the restrictions upon the President.  The
Vice President shall perform such other duties and have such other powers as
the Board of Directors, the Chairman of the Board or the President may from
time to time prescribe.  The Vice President in charge of finance, if any, shall

record, the Secretary shall also keep at the Corporation's registered office or
principal place of business a record of the original issuance of shares issued
by the Corporation and a record of each transfer of those shares that have been
presented to the Corporation for registration of transfer.  Such records shall
contain the names and addresses of all past and current shareholders of the
Corporation and the number and class of shares issued by the Corporation held
by each of them.  He shall give, or cause to be given, notice of all meetings
of the shareholders and special meetings of the Board of Directors, and shall
perform such other duties as may be prescribed by the Board of Directors, the
Chairman of the Board, or the President, under whose supervision he shall be.
He shall have custody of the corporate seal of the Corporation and he, or an
Assistant Secretary, shall have authority to affix the same to any instrument
requiring it, and when so affixed, it may be attested by his signature or by
the signature of such Assistant Secretary.  The Board of Directors may give
general authority to any other officer to affix the seal of the Corporation and

                        CERTIFICATES REPRESENTING SHARES

       Section 1.    Form of Certificates.  The Corporation shall deliver
certificates representing all shares to which shareholders are entitled.
Certificates representing shares of the Corporation shall be in such form as
shall be approved and adopted by the Board of Directors and shall be numbered
consecutively and entered in the share transfer records of the Corporation as
they are issued.  Each certificate shall state on the face thereof that the
Corporation is organized under the laws of the State of Texas, the name of the
registered holder, the number and class of shares, and the designation of the
series, if any, which said certificate represents, and either the par value of
the shares or a statement that the shares are without par value.  Each
certificate shall also set forth on the back thereof a full or summary
statement of matters required by the Act or the Articles of Incorporation to be
described on certificates representing shares, and shall contain a conspicuous
statement on the face thereof referring to the matters set forth on the back
thereof.  Certificates shall be signed by the

<PAGE>   14
Chairman of the Board, President or any Vice President and the Secretary or any
Assistant Secretary, and may be sealed with the seal of the Corporation.
Either the seal of the Corporation or the signatures of the Corporation's
officers or both may be facsimiles.  In case any officer or officers who have
signed, or whose facsimile signature or signatures have been used on such
certificate or certificates, shall cease to be such officer or officers of the
Corporation, whether because of death, resignation or otherwise, before such
certificate or certificates have been delivered by the Corporation or its
agents, such certificate or certificates may nevertheless be issued and
delivered as though the person or persons who signed the certificate or
certificates or whose facsimile signature or signatures have been used thereon
had not ceased to be such officer or officers of the Corporation.

       Section 2.    Lost Certificates.  The Corporation may direct that a new
certificate be issued in place of any certificate theretofore issued by the
Corporation alleged to have been lost or destroyed, upon the making of an
affidavit of that fact by the person claiming the certificate to be lost or
destroyed.  When authorizing the issue of a new certificate, the Board of
Directors, in its discretion and as a condition precedent to the issuance
thereof, may require the owner of the lost or destroyed certificate, or his
legal representative, to advertise the same in such manner as it shall require
and/or give the Corporation a bond in such form, in such sum, and with such
surety or sureties 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 3.    Transfer of Shares.  Shares of stock shall be transferable
only on the share transfer records of the Corporation by the holder thereof in
person or by his duly authorized attorney.  Subject to any restrictions on
transfer set forth in the Articles of Incorporation, these Bylaws or any
agreement among shareholders to which this Corporation is a party or has
notice, upon surrender to the Corporation or to the transfer agent of the
Corporation of a certificate representing shares duly endorsed or accompanied
by proper evidence of succession, assignment or authority to transfer, it shall
be the duty of the Corporation or the transfer agent of the Corporation to
issue a new certificate to the person entitled thereto, cancel the old
certificate and record the transaction upon its books.

       Section 4.    Registered Shareholders.  Except as otherwise provided in
the Act or other Texas law, the Corporation shall be entitled to regard the
person in whose name any shares issued by the Corporation are registered in the
share transfer records of the Corporation at any particular time (including,
without limitation, as of the record date fixed pursuant to Section 5 or
Section 6 of Article II hereof) as the owner of those shares and, accordingly,
shall not be bound to recognize any equitable or other claim to or interest in
such share or shares on the part of any other person, whether or not it shall
have express or other notice thereof.

                                  ARTICLE VII

                                INDEMNIFICATION

       Section 1.    General.  The Corporation shall indemnify persons who are
or were a director or officer of the Corporation both in their capacities as
directors and officers of the Corporation and, if serving at the request of the
Corporation as a director, officer, trustee, employee, agent or similar
functionary of another foreign or domestic corporation, trust, partnership,
joint venture, sole proprietorship, employee benefit plan or other enterprise,
in each of those capacities, against any and all liability and reasonable
expense that may be incurred by them in connection with or resulting from (a)
any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative, arbitrative or investigative (collectively, a
"Proceeding") , (b) an appeal in such a Proceeding, or (c) any inquiry or
investigation that could lead to such a Proceeding, all to the full extent
permitted by Article 2.02-1 of the Act.  The Corporation shall pay or
reimburse, in advance of the final disposition of the Proceeding, to all
persons who are or were a director or





                                       11
<PAGE>   15

officer of the Corporation all reasonable expenses incurred by such person who
was, is or is threatened to be made a named defendant or respondent in a
Proceeding to the full extent permitted by Article 2.02-1 of the Act.  The
Corporation may indemnify persons who are or were an employee or agent (other
than a director or officer) of the Corporation, or persons who are not or were
not employees or agents of the Corporation but who are or were serving at the
request of the Corporation as a director, officer, trustee, employee, agent or
similar functionary of another foreign or domestic corporation, trust,
partnership, joint venture, sole proprietorship, employee benefit plan or other
enterprise (collectively, along with the directors and officers of the
Corporation, such persons are referred to herein as "Corporate Functionaries")
against any and all liability and reasonable expense that may be incurred by
them in connection with or resulting from (a) any Proceeding, (b) an appeal in
such a Proceeding, or (c) any inquiry or investigation that could lead to such a
Proceeding, all to the full extent permitted by Article 2.02-1 of the Act.  The
rights of indemnification provided for in this Article VII shall be in addition
to all rights to which any Corporate Functionary may be entitled under any
agreement or vote of shareholders or as a matter of law or otherwise.

       Section 2.    Insurance.  The Corporation may purchase or maintain
insurance on behalf of any Corporate Functionary against any liability asserted
against him and incurred by him in such a capacity or arising out of his status
as a Corporate Functionary, whether or not the Corporation would have the power
to indemnify him or her against the liability under the Act or these Bylaws;
provided, however, that if the insurance or other arrangement is with a person
or entity that is not regularly engaged in the business of providing insurance
coverage, the insurance or arrangement may provide for payment of a liability
with respect to which the Corporation would not have the power to indemnify the
person only if including coverage for the additional liability has been
approved by the shareholders of the Corporation.  Without limiting the power of
the Corporation to procure or maintain any kind of insurance or arrangement,
the Corporation may, for the benefit of persons indemnified by the Corporation,
(i) create a trust fund, (ii) establish any form of self-insurance, (iii)
secure its indemnification obligation by grant of any security interest or
other lien on the assets of the Corporation, or (iv) establish a letter of
credit, guaranty or surety arrangement.  Any such insurance or other
arrangement may be procured, maintained or established within the Corporation
or its affiliates or with any insurer or other person deemed appropriate by the
Board of Directors of the Corporation regardless of whether all or part of the
stock or other securities thereof are owned in whole or in part by the
Corporation.  In the absence of fraud, the judgment of the Board of Directors
of the Corporation as to the terms and conditions of such insurance or other
arrangement and the identity of the insurer or other person participating in an
arrangement shall be conclusive, and the insurance or arrangement shall not be
voidable and shall not subject the directors approving the insurance or
arrangement to liability, on any ground, regardless of whether directors
participating in approving such insurance or other arrangement shall be
beneficiaries thereof.

                              EMPLOYMENT AGREEMENT


RECITALS:

         WHEREAS, Employer desires to obtain the services of Employee, and
Employee desires to provide services to Employer in accordance with the terms,
conditions, and provisions of this Agreement;

         NOW, THEREFORE, in consideration of the covenants and agreements of
the parties herein contained, the parties to this Agreement agree as follows:

         1.      TERM.    Employee's employment pursuant to this agreement
shall commence as of March 1, 1998 and shall continue pursuant to this
Agreement until the earliest occurrence of (i) death of Employee, (ii)
disability of employee which renders him unable to perform his obligations
hereunder for a period of at least 120 days out of any 150 consecutive day
period or which, in the written opinion of a physician of recognized ability
and reputation, mutually agreeable to Employee and Employer, renders him
permanently unable to perform his duties hereunder, (iii) discharge of Employee
by the Employer pursuant to Section 8 hereof, or (iv) February 28, 2001
provided however, that the term of this Agreement will be automatically renewed
for successive six month periods following the initial term hereof, unless one
party notifies the other party in writing that it or he intends to terminate
this Agreement at least six months prior to the termination date.  In the event
Employee elects to terminate this Agreement as provided in the preceding
sentence, Employee, at the option of the Employer, will cooperate and assist
Employer in the training of Employee's successor during that part (or all) of
the remaining term of this Agreement for which Employee is compensated at the
Salary being received by him pursuant to Section 3(a) below at the time of
termination of this Agreement.  In the event that Employee provides such notice
of termination to Employer, Employer, at its option, may choose to terminate
this Agreement on any date it chooses during such six-month period and Employee
shall be paid through such termination date.

         2.      DUTIES.  Employee will be employed as the Vice President,
Chief Financial Officer, Assistant Secretary and Treasurer of Employer, and in
such capacity will perform the normal duties associated with such position and
such other duties as may be assigned from time to time by the Board of
Directors of Employer.  During the term of this Agreement, employee shall
devote his full time, attention, and energies to the business of Employer in
order to discharge his duties faithfully, diligently, to the best of his
abilities, and in a manner consistent with any and all policies and guidelines
as may  be established by Employer from time to time.

         3.      COMPENSATION.

         (a)     Subject to the terms and conditions of this Agreement and as
compensation for the performance of his services hereunder, Employer will pay
Employee a fixed salary at a minimum annual rate of $132,000 (such rate, as may
be adjusted upward from time to time as provided by the Board of Directors of
Employer, is referred to herein as "Salary").  Employee's Salary will accrue
and be payable to Employee in accordance with payroll practices of Employer for
senior executives in effect from time to time during the term of this
Agreement.

         (b)     Additionally, on the closing date of the Employer's Initial
Public Offering on Registration Form S-1, Employer will pay Employee a lump-sum
cash amount equal to $66,000.

         (c)     At its sole discretion the Board of Directors of Employer may
develop such incentive compensation arrangements as may be determined to be
appropriate for the conduct of Employer's business and Employee's duties in
connection therewith.

         (d)     All payments to Employee pursuant to this Agreement will be
subject to deduction and withholding authorized or required by applicable law.




                                                                               1
<PAGE>   2
         4.      EMPLOYEE BENEFITS; REIMBURSEMENT OF EXPENSES.      During the
term of this Agreement, Employer shall provide such fringe benefits, including
paid sick leave, paid holidays, participation in health insurance plans, and
other employee benefit plans which are regularly maintained by Employer for it
senior executive officers in accordance with the policies of Employer in effect
from time to time.  Notwithstanding the foregoing, Employee shall be entitled
to a minimum of three weeks of paid vacation each year of this Agreement.  In
addition, during the term of this Agreement, Employer shall pay Employee the
amount of $500 each month as car allowance and reimburse Employee for his
travel, entertainment, and other business expenses incurred in connection with
his employment under this Agreement in accordance with the policies of Employer
in effect from time to time.

         5.      CONFIDENTIALITY.          Employee acknowledges that he is
being employed by Employer in a capacity in which he will receive or contribute
to information not generally known, and proprietary to Employer, about
Employer's business, services and products (collectively, "Confidential
Information").  Employee hereby acknowledges and agrees that all Confidential
Information concerning the business or affairs of Employer which Employee may
acquire in connection with or as a result of his association with Employer will
be received in strict confidence and will be used only for the purposes of
performing his duties pursuant to this Agreement and that no such Confidential
Information will be otherwise used or disclosed by Employee during or after the
term of this Agreement without the prior written consent of Employer.  Upon
termination of Employee' employment hereunder, all Confidential Information and
other documents, records, notebooks, customer lists, mailing list, business
proposals, contracts, agreements and other repositories containing information
concerning Employer or its business (including all copies hereof) in Employee's
possession, whether prepared by Employee or others, will remain with or be
returned to Employer.  Notwithstanding the foregoing, this Section shall be
inoperative as to any portion of the Confidential Information which (i) is or
becomes generally available to the public other than as a result of a
disclosure by Employee or (ii) becomes available to Employee on a
non-confidential basis and not in contravention of Employer's rights or
applicable law from a source (other than Employer) which Employee reasonable
believes is entitled to possess and disclose it.

         6.      NONCOMPETITION AND NONSOLICITATION.  Employee acknowledges and 
agrees that the training he will receive, the experience he will gain while
employed and the Confidential Information he will acquire will enable him to
injure Employer if he should violate the provisions set forth in this Section 6.
In addition, Employee acknowledges and agrees that Employer is entering into
this Agreement at the request of Employee and that Employer would not enter into
this Agreement unless this Agreement contained the terms set forth in this
Section 6.  For these reasons, Employee hereby agrees as follows:

                 (a)  During the period Employee is employed by Employer or one
         of its Affiliates and for a period of two years thereafter, except for
         services performed on behalf of Employer or one of its Affiliates,
         Employee agrees that he will not directly or indirectly either as an
         individual, a partner or a joint venturer, or in any other capacity,
         (i) invest in a company engaged in (other than investments in
         publicly-owned companies which constitute not more than 5% of the
         voting securities of any such company), or engage in, within the
         United States or other country from which Employer and its Affiliates
         derive at least 5% of their revenues (such 5% determination to be made
         as of the one-year period ending on the date of such proposed
         investment if Employee is at the time employed by Employer or as of
         the one-year period ending on the date Employee ceases to be employed
         by the Employer if the proposed investment or engagement is after the
         time Employee is employed by Employer) (the "Restricted Area") (x) the
         business of distributing or renting site-based, two-way communication
         equipment to end-users or dealers or any other business that generates
         more than 5% of the revenues of Employer and its Affiliates (such 5%
         determination to be made in the same manner as is described above)
         (the items listed under clause (x) hereto are collectively referred to
         herein as "Competitive Businesses"), or (ii) accept employment with or
         render services to Competitive Businesses that engages in such
         Competitive business within the Restricted Area as a director,
         officer, agent, employee, consultant, or any other capacity.  The
         parties agree that, if such non-competition agreement is determined by
         a court of competent jurisdiction to be unenforceable, such agreement





                                                                               2
<PAGE>   3
         should be reformed by the court to the extent necessary to be
         enforceable and to give effect to the intent of this Section 6.
         "Affiliates" of a person or entity means each entity that controls, is
         controlled by, or under common control with such person or entity.

                 (b)  During the period Employee is employed by Employer or one
         of its Affiliates and for a period of two years thereafter, neither
         Employee nor any of his Affiliates will, directly or indirectly, (i)
         solicit for the purpose of distributing or renting site-based, two-way
         communication equipment to end-users or dealers or any other business
         that generates more than 5% of the revenues of Employer and its
         Affiliates, any customer or former customer of Employer or any of its
         Affiliates, (ii) solicit for employment by himself, itself, or anyone
         else, any employee of Employer or any of its Affiliates or any person
         who was an employee of Employer or any of its Affiliates within a
         one-year period immediately preceding such solicitation or employment;
         or (iii) induce or attempt to induce, any such employee of Employer or
         any of its Affiliates to terminate such Employee's employment.

                 (c)  Employee acknowledges and agrees that the breach by him of
         the provisions of this Section 6 could not be adequately compensated
         with monetary damages and would irreparably injure Employer, and,
         accordingly, that injunctive relief and specific performance shall be
         appropriate remedies to enforce the provisions of this Section against
         Employee, and Employee waives any claim or defense that there is an
         adequate remedy at law for such breach; provided, however, that nothing
         contained herein shall limit the remedies, legal or equitable,
         otherwise available to Employer, and all remedies of Employer herein
         are in addition to any remedies available to Employer at law or
         otherwise.

                 (d)  The parties hereto acknowledge that the provisions of
         this Section 6 are supported by good and valuable consideration.
         Employee acknowledges and agrees that the limitations as to time,
         geographic area and scope of activity set forth in this Section 6 are
         reasonable and do not impose a greater restraint than is necessary to
         protect the goodwill or other business interest of Employer.  Employee
         acknowledges and recognizes that the enforcement of any of the
         noncompetition provisions in this Agreement by Employer will not
         interfere with the ability of him to pursue a proper livelihood.
         Employee further represents that he is capable of pursuing a career
         that would not violate the noncompetition provisions hereof to earn a
         proper livelihood.

                 (e)  The parties hereto intend all provisions of this
         Agreement including the provisions set forth in this Section 6 hereof
         to be enforced to the fullest extent permitted by law.  Accordingly,
         should a court of competent jurisdiction determine that the scope of
         any provision herein is too broad to be enforced as written, the
         parties intend that the court reform the provision to such narrower
         scope as it determines to be reasonable and enforceable.  In addition,
         however, Employee agrees that the noncompetition agreements,
         non-solicitation agreements, and nonemployment agreements set forth
         above each constitute separate agreements independently supported by
         good and adequate consideration and shall be severable from the other
         provisions of, and shall survive, this Agreement.  If any provision of
         this Agreement is held to be illegal, invalid or unenforceable under
         present or future laws effective during the date hereof, such
         provision shall be fully severable and this Agreement shall be
         construed and enforced as if such illegal, invalid or unenforceable
         provision never comprised a part of this Agreement; and the remaining
         provisions of this Agreement shall remain in full force and effect and
         shall not be affected by the illegal, invalid or unenforceable
         provision or by its severance herefrom.  Furthermore, in lieu of such
         illegal, invalid or unenforceable provision, there shall be added
         automatically as part of this Agreement, a provision as similar in its
         terms to such illegal, invalid or unenforceable provision as may be
         possible and be legal, valid and enforceable.

         7.      INJUNCTIVE RELIEF.  This section has been intentionally
                 deleted.





                                                                               3

         8.      TERMINATION.

                 (a)  Employer may terminate Employee's employment with or
         without Cause (as defined herein).  If Employee's employment is
         terminated for Cause, Employee will be paid Salary to the date of such
         termination notice (less all amounts required to be withheld or
         deducted therefrom and all undisputed amounts owed or due by Employee
         to Employer).

                 (b)  In the event Employer terminates Employee other than for
         Cause, except as provided for in Section 8(e) hereof, Employer shall
         (i) continue to pay Salary to Employee through the stated term of this
         Agreement (less all amounts required to be withheld or deducted
         therefrom and all undisputed amounts owed or due by Employee to
         Employer), and (ii) continue to provide Employee during the term of
         this Agreement health insurance with coverage no less than the
         coverage available during such period to Employer's senior executive
         officers, and Employer shall have no other obligation thereunder.

                 (c)  If no other provision in this SECTION 8 is applicable and
         in the event this Agreement terminates pursuant to the expiration of
         the term set forth in SECTION 1, Employee will be paid only Salary as
         has been earned to the date of termination (less all amounts required
         to be withheld or deducted therefrom and all undisputed amounts owed or
         due by Employee to Employer) or such longer period as he is entitled
         pursuant to the provisions of SECTION 9.

                 (d)  If Employee dies during the term hereof, this Agreement 
         will terminate, and Employer will pay to the estate of Employee the
         Salary which would otherwise be payable to Employee up to the end of
         the month in which his death occurs (less all amounts required to be
         withheld or deducted therefrom and all undisputed amounts owed or due
         by Employee to Employer).

                 (e)  If Employee's employment is terminated by Employer
         without Cause, Employee shall use his best efforts to seek other
         reasonably comparable employment.  If Employee becomes employed during
         the remaining term of this Agreement, Employer's obligation to provide
         health insurance to Employee shall terminate upon Employee's gaining
         such other employment.  If Employee gains other employment that
         provides him with compensation equal to 75% or more of Employee's
         Salary as of the date he ceases to be employed by Employer, Employer's
         obligation to pay Salary hereunder shall terminate at the earlier of
         six months after Employee gains such other employment or the end of
         the stated term of this Agreement.  If Employee's new employment does
         not provide him with compensation equal to 75% or more of his Salary
         as of the date he ceased to be employed by Employer, Employer's
         obligation to pay 100% of the Salary hereunder shall terminate at the
         earlier of six months after Employee gains such other employment or
         the end of the stated term of this Agreement, and if the end of such
         six-month period is before the end of the stated term of this
         Agreement then Employer shall also be obligated to pay to Employee
         from the end of such six-month period until the end of the sated term
         of this Agreement the difference between 75% of Employee's Salary as
         of the date Employee ceased to be employed by Employer and Employee's
         compensation from his new employment.  Not withstanding the foregoing,
         payments under this Agreement after termination shall reduce amounts
         payable after termination under the Severance Agreement ("Severance
         Agreement"), if any, that is entered into between Employer and
         Employee

                 (f)  For the purposes of this Agreement, "Cause" shall mean:

                          (i)   the failure or inability for any reason of
                 Employee to devote his full business time to Employer's
                 business,

                          (ii)  the failure of Employee to diligently or

                 than any such failure resulting from incapacity due to
                 physical injury or illness or mental illness as such is
                 provided for in SECTION 9); provided, that, before a
                 termination of Employee pursuant to this Section 8(g)(ii)
                 shall be considered for "Cause", Employer must give Employee
                 10 days' notice and an opportunity during such 10 day





                                                                               4

                 period to cure such failure,

                          (iii)  any intentional dishonest or fraudulent act or
                 course of conduct by Employee that is detrimental to Employer,
                 or other act or course of conduct by Employee constituting a
                 criminal act, or the commission by Employee of an act or a
                 course of conduct involving moral turpitude, or the commission
                 by Employee of an act that renders Employee incapable of
                 performing his duties under this Agreement or materially
                 adversely affects Employer's business reputation,

                          (iv)  any material breach by Employee of any of the
                 terms of, or the material failure to perform any covenant
                 contained in, this Agreement; provided, that, before a
                 termination of Employee pursuant to this Section 8(g)(iv)
                 shall be considered for "Cause" if such breach or failure is
                 curable, Employer must give Employee 10 days' notice and an
                 opportunity during such 10 day period to cure such breach or
                 failure, or the violation by Employee of written policies
                 established by Employer with respect to the operation of its
                 business and affairs or employee's failure to carry out the
                 instructions of the Board of Directors, Chairman or President
                 of Employer, provided that, before a termination of Employee
                 pursuant to this section 8(g)(v) shall be considered for Cause
                 if such violation or failure is curable, Employer must give
                 Employee 10 days' notice and an opportunity during such 10 day
                 period to cure such violation or failure.

         For purposes of this Agreement, Employee's act, or failure to act will
         be deemed "intentional" only if done, or omitted to be done, without
         reasonable belief that his action or omission was in the best interest
         of Employer.

         9.      DISABILITY.  If Employee is unable to perform his assigned
duties by reason of illness, injury or incapacity (other than as a result of
abuse of drugs, alcohol or other substances), he will be entitled to receive
such disability benefits as are provided by Employer's disability policies for
its other senior executive officers.  Notwithstanding the foregoing, upon any
Disability as described in Section 1 hereof, Employee's employment under this
Agreement shall terminate.

         10.     BINDING NATURE.

                 (a)  Employer will require any successor and any corporation
         or other legal person which is in control of such successor (as
         "control" is defined in Regulation 230.405 or any successor rule or
         regulation promulgated under the Securities Act of 1933, as amended)
         to all or substantially all of the business and/or assets of Employer
         (by purchase, merger, consolidation or otherwise), by agreement in
         form and substance satisfactory to Employee, to expressly assume and
         agree to perform this Agreement in the same manner and to the same
         extent that Employer would be required to perform it if no such
         succession had taken place.  Notwithstanding the foregoing, any such
         assumption shall not, in any way, affect or limit the liability of the
         Employer under the terms of this Agreement or release the Employer from
         any obligations hereunder.  As used in this Agreement "Employer" shall
         mean Employer as hereinbefore defined and any successor to its business
         and/or all or part of its assets as aforesaid which executes and
         delivers the agreement provided for in this SECTION 10 or which
         otherwise becomes bound by all the terms and provisions of this
         Agreement by operation of law.

                 (b) This Agreement and all the rights of Employee under this
         Agreement will inure to the benefit of and will be enforceable by
         Employee's personal or legal representatives, executors,
         administrators, successors, heirs, distributees, devisees and
         legatees.

                 (c)  Except as set forth above, neither this Agreement, nor
         any of the rights, interests or





                                                                               5
<PAGE>   6
         obligations hereunder shall be assigned by either party hereto,
         without the prior written consent of the other party (except that
         Employer may assign this Agreement to one of its affiliates without
         Employees consent and such assignment shall not release Employer of
         any obligations hereunder), nor is this Agreement intended to confer
         upon any other person other than the parties hereto any rights or
         remedies hereunder.

         11.     SEVERABILITY.  If any provision of this Agreement is declared
or found to be illegal, unenforceable or void, in whole or in part, then both
parties will be relieved of all obligations arising under such provision, but
only to the extent it is illegal, unenforceable or void.  The intent and
agreement of the parties to this Agreement is that this Agreement will be
deemed amended by modifying any such illegal, unenforceable or void provision
to the extent necessary to make it legal and enforceable while preserving its
intent, or if such is not possible, by substituting therefor another provision
that is legal and enforceable and if the remainder of this Agreement will not
be affected by such declaration or finding and is capable of substantial
performance, then each provision not so affected will be enforced to the extent
permitted by law.

         12.     WAIVER.  No delay or omission by either party to this
Agreement to exercise any right or power under this Agreement will impair such
right or power or be construed as a waiver thereof.  A waiver by either of the
parties to this Agreement of any of the covenants to be performed by the other
or any breach thereof  will not be construed to be a waiver of any succeeding
breach thereof or of any other covenant contained in this Agreement.  All
remedies provided for in this Agreement will be cumulative and in addition to
and not in lieu of any other remedies available to either party at law, in
equity, or otherwise.

         13.     GOVERNING LAW.  This Agreement will be governed by and
construed in accordance with the laws of the State of Texas without giving
effect to any principle of conflict-of-laws that would require the application
of the law of any other jurisdiction.

         14.     NOTICES.  For purposes of this Agreement, notices and all
other communications provided for in this Agreement shall be in writing and
shall be deemed to have been duly given when delivered or mailed by United

will of Employer and BearCom; and

         WHEREAS, the execution and delivery of this Agreement is a condition
precedent to the obligations of Condor and Employee pursuant to the Asset
Purchase Agreement; and

Agreement.  Employees duties hereunder shall be those normally incident to his
position as President and Chief Executive Officer of Employer, which duties

Employee shall devote substantially all his business time and efforts to the
business of Employer; provided, however, that subject to the provisions of
Section 8, Employee may devote limited time to other business matters in which

                 (a)      BASE SALARY.  Employer shall pay to Employee a base

Employee shall be eligible to participate in all employee benefit plans and
arrangements now in effect or which may hereafter be established in
substitution of or in addition to such employee benefit plans and arrangements,

Officer of Employer and adequate for the performance of his duties; provided,
however, that if Employer's executive offices are relocated, which relocation

                                     - 2 -
<PAGE>   3
                 (e)      For Cause, where "Cause" shall mean: (i) any
misappropriation by Employee of funds or property of Employer or any of its
affiliates; (ii) the conviction of Employee for a felony or any crime involving
moral turpitude; (iii) refusal of Employee to perform his duties and
responsibilities, persistent neglect of duty or chronic absenteeism, which
remains uncured for ten (10) days after written notice from Employer to
Employee of such alleged Cause; (iv) a breach by Employee of the provisions of
Section 7 or Section 8; or (v) any attempt by Employee to obtain a personal
profit from any transaction in which Employee has an interest adverse to
Employer unless such adverse interest and the potential profit are disclosed in
writing to the Board and approved in advance of such transaction.

                 Any termination pursuant to subparagraph (a) (b), (c) or (e)
of this Section shall be communicated by a written notice ("Notice of
Termination"), such notice to set forth with specificity the grounds for
termination if the result of "Cause".  Employee's employment under this
Agreement shall be deemed to have terminated as follows: (i) if Employee's
employment is terminated pursuant to subparagraph (b) above, on the date of his
death; or (ii) if Employee's employment is terminated pursuant to subparagraphs
(a), (c) or (e) above, on the date on which Notice of Termination is given; or
(iii) if Employee's employment is terminated pursuant to subparagraph (d)
above, ten (10) days after the date on which a Notice of Termination is given.
The date on which termination is deemed to have occurred pursuant to this
paragraph is hereinafter referred to as the "Date of Termination."

         6.      PAYMENTS ON TERMINATION.  Except as otherwise provided in this
Section, in the event that Employee's employment is terminated, Employer shall
pay to Employee his full Base Salary through the Date of Termination together
with all benefits and other compensation, if any, due and owing as of that
date.  In the event that Employee's employment is terminated at any time by
Employee for "Good Reason" (as defined in this Section) or by Employer without
Cause, then Employer shall pay to Employee on the Date of Termination a lump
sum cash payment equal to all Compensation Benefits that are due, and all Base
Salary that would have become due to Employee under the terms of this Agreement
if the employment had not been terminated.  For purposes of this Section 6 and
Section 8(e), "Good Reason"  shall include: (i) the assignment to Employee of
any duties inconsistent in any material respect with Employee's position
(including status, offices, titles and reporting requirements), authority,
duties or responsibilities as contemplated by Section 3, or any other action by
Employer which results in a diminution of such position, authority, duties or
responsibilities, excluding for this purpose any action taken with the consent
of Employee and any isolated, insubstantial and inadvertent action taken in
good faith and which is remedied by Employer promptly after receipt of notice
of such action given by Employee; (ii) any material breach by Employer of any
of the terms or conditions of this Agreement which remains uncured following
ten (10) days after written notice to Employer of such alleged breach; or (iii)
any material breach by Employer of any of the terms or conditions of the Asset
Purchase Agreement which remains uncured following ten (10) days after written
notice to Employer of such alleged breach.

         7.      DISCLOSURE AND PROTECTION OF CONFIDENTIAL INFORMATION.

                 (a)      For purposes of this Agreement, "Confidential
Information" means knowledge, information and material which is proprietary to
Employer, of which Employee may obtain knowledge or access through or as a
result of his employment by Employer (including information conceived,
originated, discovered or developed in whole or in part by Employee).
Confidential Information includes, but is not limited to, (i) technical
knowledge, information and material such as trade secrets, processes, formulas,
data, know-how, improvements, inventions, computer programs, drawings, patents,
and experimental and development work techniques, and (ii) marketing and other
information, such as supplier lists, customer lists, marketing and business
plans, business or technical needs of customers, consultants, licensees or
suppliers and their methods





                                     - 3 -
<PAGE>   4
of doing business, arrangements with customers, consultants, licensees or
suppliers, manuals and personnel records or data.  Confidential Information
also includes any information described above which Employer obtains from
another party (including Condor and its affiliates) and which Employer treats
as proprietary or designates as confidential, whether or not owned or developed
by Employer.  Notwithstanding the foregoing, any information which is or
becomes available to the general public otherwise than by breach of this
Section 7 shall not constitute Confidential Information for purposes of this
Agreement.

                 (b)      During the term of this Agreement and thereafter,
Employee agrees to hold in confidence all Confidential Information and not to
use such information for Employee's own benefit or to reveal, report, publish,
disclose or transfer, directly or indirectly, any Confidential Information to
any person or entity, or to utilize any Confidential Information for any
purpose, except in the course of Employee's work for Employer.

                 (c)      Employee will abide by any and all security rules and
regulations, whether formal or informal, that may from time to time be imposed
by Employer for the protection of Confidential Information, and will inform
Employer of any defects in, or improvements that should be made to, such rules
and regulations.

                 (d)      Employee will notify Employer in writing immediately
upon receipt of any subpoena, notice to produce, or other compulsory order or
process of any court of law or government agency if such document requires or
may require disclosure or other transfer of Confidential Information.  For this
purpose, Employee irrevocably nominates and appoints Employer (including any
attorney retained by Employer), as his true and lawful attorney-in-fact, to act
in Employee's name, place and stead to perform any act which Employee might
perform to defend and protect against any disclosure of Confidential
Information.

                 (e)      Upon termination of his employment, Employee will
deliver to Employer any and all records and tangible property that contain
Confidential Information that are in his possession or under his control.

         8.      COVENANT NOT TO COMPETE.

                 (a)      Employee covenants and agrees that until the later of

                 (c)      If any court shall determine that the duration or
geographical limit of any covenant contained in this Section 8 is
unenforceable, it is the intention of the parties that covenant shall not
thereby be terminated but shall be deemed amended to the extent required to
render it valid and enforceable, such amendment to apply only in the
jurisdiction of the court that has made such adjudication.

                 (d)      Employee acknowledges and agrees that the covenants
contained in Sections 7 and 8 are of the essence in this Agreement, that each
of such covenants is reasonable and necessary to protect and preserve the
interests, properties, and business of Employer, and that irreparable loss and
damage will be suffered by Employer should Employee breach any of such
covenants.  Employee further represents and acknowledges that he shall not be
precluded from gainful engagement in a satisfactory fashion by the enforcement
of these provisions.

                 (e)      This Section 8 shall not be effective in the event
Employee is terminated by Employer without Cause or by Employee for Good Reason
(as defined in Section 6) but shall be effective following termination for any
other reason.

         9.      AVAILABILITY OF INJUNCTIVE RELIEF.  Employee acknowledges and
agrees that any breach by him of the provisions of Sections 7 or 8 hereof will
cause Employer irreparable injury and damage for which it cannot be adequately
compensated in damages.  Employee therefore expressly agrees that Employer
shall be entitled to seek injunctive and/or other equitable relief, on a
temporary or permanent basis to prevent any anticipatory or continuing breach
of this Agreement or any part hereof, and is in addition to any other remedies
available to it.  Nothing herein shall be construed as a waiver by Employer of
any right it may have or hereafter acquired to monetary damages by reason of
any injury to its property, business or reputation or otherwise arising out of
any wrongful act or omission of Employee.

         10.     ENTIRE AGREEMENT; MODIFICATION.  This Agreement sets forth the
entire understanding of the parties with respect to the subject matter hereof,
supersedes all existing agreements between them concerning such subject matter,
and may be modified only by a written instrument duly executed by each party.

         11.     NOTICES.  Any notice required or permitted hereunder shall be

         12.     WAIVER.  Any waiver by either party of a breach of any
provision of this Agreement shall not operate as or be construed to be a waiver
of any other breach of such provision or of any breach of any other provision
of this Agreement. The failure of a party to insist upon strict adherence to
any term of this Agreement on one or more occasions shall not be considered a
waiver or deprive that party of the right thereafter to insist upon strict
adherence to that term or any other term of this Agreement.  All waivers must
be in writing.

         13.     BINDING EFFECT.  Employer's rights and obligations under this

rights to enforce the confidentiality or non-competition provisions under
Section 7 or 8 of this Agreement to any successor entity shall not have any
effect whatsoever upon the binding nature or enforceability of this Agreement.
The provisions of this Agreement shall be binding upon and inure to the benefit
of Employer (and its successors and assigns) and Employee (and his heirs and
personal representatives).

         14.     HEADINGS.  The headings in this Agreement are solely for
convenience of reference and shall be given no effect in the construction or
interpretation of this Agreement.

         15.     GOVERNING LAW; VENUE.  This Agreement will be governed and
construed in accordance with the laws of the State of Texas, without giving
effect to rules governing conflicts of law, with proper venue with respect to
all disputes related to this Agreement being Dallas, Texas.

         16.     INVALIDITY.  The invalidity or unenforceability of any term of
this Agreement shall not invalidate, make unenforceable or otherwise affect any
other term of this Agreement, which shall remain in full force and effect.

         17.     ATTORNEYS' FEES.  In the event any dispute or litigation
arises hereunder between any of the parties hereto, the prevailing party shall
be entitled to all reasonable costs and expenses incurred by it in connection
therewith (including, without limitation, all reasonable attorneys' fees and
costs incurred before and at any trial or other proceeding and at all tribunal
levels), as well as all other relief granted in any suit or other proceeding.

                   FOURTH AMENDED AND RESTATED LOAN AGREEMENT

         This Fourth Amended and Restated Loan Agreement (this "Agreement") is
entered into as of August 29, 1997 by and between BEARCOM OPERATING, L.P. (the
"Company") and WELLS FARGO BANK (TEXAS), NATIONAL ASSOCIATION, formerly First
Interstate Bank of Texas, N.A. (the "Bank").

                                    Recitals

         WHEREAS, the Company and the Bank have been parties to that certain
Third Amended and Restated Loan Agreement dated as of November 1, 1996 (the "Old
Agreement"), under which the Bank made certain loans and advances to the Company
secured by all or substantially all of the Company's assets; and

         WHEREAS, the Company has requested additional financial accommodations,
and the Company and the Bank have agreed to amend and restate the terms and
conditions of the Old Agreement, as set forth hereinafter.

                                   Agreements

         In consideration of the Bank's making the following described loans,
the mutual covenants herein contained and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged by each of the
parties hereto, the Company and the Bank agree as follows:

                i.        The $15,000,000 Revolving Line of Credit.

         (a)    Subject to, and upon the terms, conditions, covenants and
agreements contained herein, the Bank agrees to loan the Company, at any time,
and from time to time prior to the maturity of the Company's promissory note
executed in conjunction with this Agreement, such amounts as the Company may
request up to but not exceeding an aggregate principal sum at any time
outstanding equal to $15,000,000 (the "Revolving Line of Credit"); within such
limits and during such period, the Company may borrow, repay, and re-borrow
hereunder. All loans under the Revolving Line of Credit shall be evidenced by
the Company's Renewal Master Revolving Credit Note dated the date hereof (the
"Revolving Note"), in form and substance satisfactory to the Bank, payable to
the order of the Bank, and bearing interest upon the terms provided therein (but
in no event to exceed the maximum non-usurious interest rate permitted by law).
The principal of and interest on the Revolving Note shall be due and payable as
set forth on the face of the Revolving Note. Notation by the Bank on its records
shall constitute prima facie evidence of the amount and date of any payment or
borrowing thereunder. The Revolving Line of Credit shall be used by the Company
for its ordinary working capital needs, or for general corporate purposes, or
for its acquisition of all or substantially all of the assets or capital stock
of one or more operating businesses (each such acquisition a "Revolver
Acquisition").


FOURTH AMENDED AND RESTATED LOAN AGREEMENT - PAGE 1
<PAGE>   2




         (b)    Advances Related to Letters of Credit. Advances under the 
Revolving Line of Credit may also be made to fund Letters of Credit (as
hereinafter defined) that are issued under the Revolving Note and are drawn
upon, provided, the Bank may, in its own discretion, advance funds under the
Revolving Line of Credit to fund such Letters of Credit (as hereinafter defined)
when the Company does not reimburse the Bank for such funding. All such advances
shall be added to the principal amount of the Revolving Note and shall be
reimbursable to the Bank by the Company upon demand therefor.

                ii.         The $5,000,000 Acquisition Line of Credit. Subject 
                        to, and upon the terms, conditions, covenants and
                        agreements contained herein, at the Company's request
                        the Bank has agreed to loan the Company up to the sum of
                        $5,000,000 to be utilized by the Company solely for its
                        acquisition of all or substantially all of the assets or
                        capital stock of one or more operating businesses (each
                        an "Acquisition"); within such limits and until October
                        31, 1997 (but not thereafter), the Company may borrow,
                        repay and reborrow hereunder. Such loans (the
                        "Acquisition Indebtedness") are evidenced by the
                        Company's Acquisition Note dated November 1, 1996 (the
                        "Acquisition Note"), executed concurrently with the
                        execution of the Old Agreement, payable to the order of
                        the Bank, and bearing interest upon the terms provided
                        therein (but in no event to exceed the maximum
                        non-usurious interest rate permitted by law). The
                        Acquisition Indebtedness shall convert from a line of
                        credit to a term repayment on November 1, 1997 in
                        accordance with the terms of the Acquisition Note. The
                        principal of and interest on the Acquisition Note shall
                        be due and payable as set forth on the face of the
                        Acquisition Note. Notation by the Bank on its records
                        shall constitute prima facie evidence of the amount and
                        date of any payment or borrowing thereunder.

                iii.        Renewals and Extensions. All renewals, extensions,
                        modifications and rearrangements of the Revolving Note
                        and the Acquisition Note, if any, shall be deemed to be
                        made pursuant to this Agreement, and accordingly, shall
                        be subject to the terms and provisions hereof, and the
                        Company shall be deemed to have ratified, as of such
                        renewal, extension, modification or rearrangement date,
                        all of the representations, covenants and agreements
                        herein set forth.

                iv.         Old Agreement Superseded. This Agreement supersedes
                        and replaces the Old Agreement in its entirety;
                        provided, that the Company's liability to the Bank for
                        outstanding loans and other indebtedness under the Old
                        Agreement and its predecessors (the amount of which the
                        Company acknowledges is, as of August 28, 1997,
                        $8,934,300 under the Revolving Note and $5,000,000 under
                        the Acquisition Note), shall continue in full force and
                        effect under the terms hereof. The foregoing amounts of
                        indebtedness shall constitute the initial outstanding
                        principal amount under the Revolving Note and the
                        Acquisition Note, respectively.


FOURTH AMENDED AND RESTATED LOAN AGREEMENT - PAGE 2

                v.          Letters of Credit. Subject to the conditions herein,
                        the Bank shall from time to time, at the request of the
                        Company, issue Letters of Credit (herein so called) to
                        Company's vendors for the acquisition of inventory for
                        the Company. The aggregate outstanding amount of any
                        Letters of Credit issued by Bank hereunder shall
                        constitute a portion of the Revolving Line of Credit,
                        and shall in no event exceed the sum of $2,000,000. The
                        fees for such issuance shall be in accordance with the
                        Bank's then existing fee schedule therefor. Such Letters
                        of Credit shall be considered in computing the amount of
                        funds available to the Company, as provided in Section 6
                        herein. The Bank shall not be obligated: (a) to issue
                        Letters of Credit if the issuance of same would cause
                        the Outstanding Credit (as hereinafter defined) to
                        exceed the Borrowing Base (as hereinafter defined); (b)
                        to issue such Letters of Credit with an expiration date
                        after the maturity date of the Revolving Note; and (c)
                        to extend the expiration date of such Letters of Credit
                        to a date after the maturity date of the Revolving Note.

                vi.         Availability Under Revolving Note.

                                (i)         Revolving Note. The aggregate 
                                        principal amount at any time outstanding
                                        under the Revolving Note and the 
                                        Acquisition Note, including without 
                                        limitation the face amount of all 
                                        outstanding Letters of Credit issued 
                                        for the account of the Company (said 
                                        principal amount collectively being 
                                        referred to herein as the "Outstanding 
                                        Credit") shall not at any time exceed 
                                        the Borrowing Base, as hereinafter 
                                        defined.

                                (ii)        Borrowing Base Compliance. In the 
                                        event the Outstanding Credit at any time
                                        exceeds the Borrowing Base, then the
                                        Company shall immediately make such
                                        payments to the Bank necessary to reduce
                                        the Outstanding Credit to an amount such
                                        that the Outstanding Credit is less than
                                        or equal to the amount of the Borrowing
                                        Base.

                  vii.          Borrowing Base.

         (a) The "Borrowing Base" shall be equal to an amount that is 5.50 times
the Free Cash Flow of the Company; calculated on a rolling, preceding 12-month
basis. The term "Free Cash Flow" means the Company's net income plus
depreciation and amortization, less any non- discretionary, maintenance capital
expenditures (which shall include, without limitation, all amounts spent for the
purchase and replacement of rental equipment). The Free Cash Flow, and all
components thereof, shall be computed by the Company and reported to the Bank in
accordance with generally accepted accounting principles, consistently applied
("GAAP").


FOURTH AMENDED AND RESTATED LOAN AGREEMENT - PAGE 3
<PAGE>   4


         (b)    For purposes of determining the Borrowing Base upon, or 
following, an Acquisition or a Revolver Acquisition by the Company, the Company
shall include in the calculation in Subsection 7(a) hereinabove the Free Cash
Flow for the division, corporation or other entity that is the subject of such
acquisition, to be computed by the Company and reported to the Bank in
accordance with GAAP, but without any adjustments for efficiencies that the
Company might realize in its operations after the acquisition.

         (c)    In the event that the Bank disputes the amount of the Borrowing
Base as calculated and reported by the Company, the Bank may, upon notice to the
Company, make any reasonable adjustment to the Borrowing Base for purposes of
determining availability under the Revolving Note and the Acquisition Note.

                viii.   Requests for Advances. Advances under the Revolving Line
                        of Credit may be made by telephonic oral request,
                        written request signed by an authorized officer of the
                        Company or by telephonic facsimile request, provided
                        that any such advance shall be deposited in an account
                        of the Company, unless such authority for telephonic
                        oral requests or telephonic facsimile requests is
                        revoked in writing by John P. Watson, as designated
                        agent of the Company (or such other designated agent as
                        the Bank approves in writing), and such revocation is
                        actually received by the Bank (the "Revocation"). Any
                        telephonic oral request shall be followed with a written
                        request for an advance in accordance with this Agreement
                        within twenty- four (24) hours. In consideration of the
                        Bank's permitting the Company to make telephonic oral
                        requests and telephonic facsimile requests for advances
                        under the Revolving Note until Revocation, the Company
                        covenants and agrees to assume liability for and to
                        protect, indemnify and hold the Bank harmless from any
                        and all liabilities, obligations, damages, penalties,
                        claims, causes of action, costs, charges and expenses,
                        including attorneys' fees and expenses of employees,
                        which may be imposed, incurred by or asserted against
                        the Bank (other than that caused by Bank's willful
                        misconduct) by reason of any loss, damage or claim
                        howsoever arising or incurred because of or out of or in
                        connection with (i) any action of the Bank pursuant to
                        telephonic oral requests and telephonic facsimile
                        requests for advances under the Revolving Line of
                        Credit, (ii) the breach of any provisions of this
                        Agreement by the Company, (iii) the transfer of funds
                        pursuant to such telephonic oral requests and telephonic
                        facsimile requests, or (iv) the Bank's honoring or
                        failing to honor any telephonic oral request or
                        telephonic facsimile request for any reason. The Bank is
                        entitled to rely upon and act upon telephonic oral
                        requests and telephonic facsimile requests made or
                        purportedly made by any of the officers or employees
                        specified in the resolutions delivered to the Bank of
                        even date herewith, as supplemented in writing from time
                        to time and accepted by the Bank, and the Company shall
                        be unconditionally and absolutely estopped from denying
                        (i) the authenticity and validity of any such
                        transaction so acted upon by the Bank once the Bank has
                        advanced funds under the Revolving Line of Credit and
                        deposited or

                        transferred such funds as requested in any such
                        telephonic oral request or telephonic facsimile request,
                        and (ii) the Company's liability and responsibility
                        therefor.

                ix.         Prepayments. Any prepayment on the Revolving Note 
                        and the Acquisition Note (collectively, the "Notes")
                        shall be paid at the offices of the Bank. The Company
                        shall be entitled to prepay the Notes from time to time
                        and at any time, in whole or in part, without notice or
                        penalty except as set forth in the Notes. All
                        prepayments on the Notes shall be applied as set forth
                        in the Notes. No prepayment shall relieve the Company of
                        the obligation to pay the principal and interest on the
                        Notes until such time as all obligations are paid in
                        full.

                x.          Collateral for the Loans. The Outstanding Credit and
                        any and all other indebtedness of any kind whatsoever
                        now owing or hereafter arising under this Agreement
                        (which shall collectively be referred to herein as the
                        "Bank Indebtedness") shall be secured by the following
                        (hereinafter called the "Collateral"), as to which the
                        Company hereby grants to the Bank a security interest:

                                        thereof, including without limitation,

                                (ix)        An event of default or Event of
                                        Default occurs under any guaranty
                                        executed in connection with this
                                        Agreement or the Old Agreement, or under

                from such party.

        xx.         Waiver. No failure to exercise and no delay in exercising on
                the part of the Bank of any right, power or privilege
                hereunder, shall operate as a waiver thereof; nor shall any
                single or partial exercise of any right, power or privilege
                hereunder, preclude any other or further exercise thereof, or
                the exercise of any other right, power or privilege. The rights

                renewal thereof.

        xxii.       Amendment. This Agreement may not be amended except in 
                writing signed by the Company and the Bank.

        xxiii.      Successors. This Agreement shall be binding upon and inure

                assigns of each party hereto.

        xxiv.       Severability. In the case any one or more of the provisions
                contained in the Loan Documents should be invalid, illegal, or
                unenforceable, in any respect, the validity, legality, and
                enforceability of the remaining provisions contained therein
                shall not in any way be affected thereby.

        xxv.        Interest. It is the intention of the parties hereto to
                comply with the laws of the State of Texas. Accordingly, it
                is agreed that, notwithstanding any provisions to the contrary
                in the Loan Documents, in no event shall said Loan Documents
                require the payment or permit the collection of interest, as
                defined under the laws of the State of Texas, in excess of the
                maximum amount permitted by such laws. If any such excess of
                interest is contracted for, charged or received, under the Loan
                Documents, or in the event the maturity of the indebtedness
                evidenced by the Notes is accelerated in whole or in part, or in
                the event that all or part of the principal or interest of the
                Notes shall be prepaid, so that under any of such circumstances
                the amount of interest contracted for, charged, or received
                under the Loan Documents on the amount of principal actually
                outstanding from time to time thereunder shall exceed the
                maximum amount of interest permitted by the laws of the State of
                Texas, then in any such event (a) the provisions of this section
                shall govern and control, (b) neither the Company nor any other
                person or entity now or hereafter liable for the payment of the
                Notes shall be obligated to pay the amount of such interest to
                the extent that it is in excess of the maximum


FOURTH AMENDED AND RESTATED LOAN AGREEMENT - PAGE 21
<PAGE>   22

                amount of interest permitted to be contracted for by, charged to
                or received from the party obligated thereon under the laws 
                of the State of Texas, (c) any such excess which may have
                been collected shall be either applied as a credit against the
                then unpaid principal amount on the Notes or refunded to the
                person paying the same, at the holder's option, and (d) the
                effective rate of interest shall be automatically reduced to the
                maximum lawful rate of interest permitted to be contracted for
                by, charged to or received from the party obligated thereon
                under the laws of the State of Texas as now or hereafter
                construed by the courts having jurisdiction thereof. It is
                further agreed that without limitation of the foregoing, all
                calculations of the rate of interest contracted for, charged or
                received under the Loan Documents, for the purpose of
                determining whether such rate exceeds the maximum lawful rate of
                interest, shall be made, to the extent permitted by the laws of
                the State of Texas, by amortizing, prorating, allocating and
                spreading in equal parts during the period of the full stated
                terms of the Notes all interest at any time contracted for,
                charged or received from the undersigned or otherwise by the
                holder or holders thereof in connection with such Notes.

                agrees that the Bank may sell to other lenders participations
                in the loans incurred by the Company pursuant hereto and,
                therefore, as security for the due payment and performance of
                all indebtedness and other liabilities and obligations of the
                Company to the Bank under the Loan Documents and an other
                obligation of the Company to the Bank, whether now existing or
                hereafter arising, and to such lenders arising now by reason of
                such participations or otherwise, the Company hereby grants to
                the Bank and to such lenders, a lien on and security interest in

                the Company, whether in regular or special depository accounts
                or otherwise, and any and all monies, securities and other
                property of the Company, and the proceeds thereof now or
                hereafter held or received by or in transit to the Bank and such
                lenders or either or any of them, from or for the Company
                whether for safekeeping, custody, pledge, transmission,
                collection or otherwise and any such deposit, sums, monies,
                securities and other property may at any time after Default be
                set-off, appropriated and applied by the Bank and by such
                lenders, or either or any of them, against any indebtedness,
                liabilities or other obligations, whether now existing or
                hereafter arising, of the Company or any of them, under this
                Agreement and the Notes, or otherwise whether or not such
                indebtedness, liabilities or other obligation is then due or
                secured by any indebtedness, liabilities or other obligation is
                then due or secured by any collateral or if it is so secured
                whether or not such collateral held by the Bank or such lenders
                is considered to be adequate.

                                FIRST AMENDMENT
                                       TO
                   FOURTH AMENDED AND RESTATED LOAN AGREEMENT

         This First Amendment to Fourth Amended and Restated Loan Agreement
(this "Amendment") is entered into effective as of March 27, 1998, by and
between the following parties:

         a.     BEARCOM OPERATING, L.P. (the "Company"), and

         b.     WELLS FARGO BANK (TEXAS), NATIONAL ASSOCIATION (the "Bank").

                                    RECITALS:

         a.     On August 29, 1997, the Company and the Bank entered into that
certain Fourth Amended and Restated Loan Agreement (the "Loan Agreement"; terms
defined in the Loan Agreement and used herein shall have the definitions herein
as ascribed in the Loan Agreement, unless otherwise defined herein) in which the
Bank agreed to provide certain loans and other accommodations to the Company
upon the conditions and in accordance with the covenants set forth therein.

         b.     Concurrently herewith, Condor Holdings, Inc. ("Condor 
Acquisition Corp."), a direct subsidiary of BearCom, Inc. ("Parent"), who is the
Company's indirect parent, is entering into an asset purchase agreement whereby
Condor Acquisition Corp. will purchase all or substantially all of the assets of
Condor Communications, Inc. ("Condor") for a total cash purchase price not to
exceed Ten Million Dollars ($10,000,000) (the "Condor Acquisition").

         c.     The Company has requested that the Bank provide funds for the 
Condor Acquisition and permit it to loan or otherwise distribute such funds in
an amount not to exceed Ten Million Dollars ($10,000,000) to Parent (such loan
or distribution in such amount herein, the "Condor Acquisition Advance"). Parent
will then contribute, loan or otherwise distribute such funds to Condor
Acquisition Corp. The Bank has agreed to provide such funds and permit the
Condor Acquisition Advance upon and subject to the terms and conditions of this
Amendment and the terms and conditions of the Loan Agreement, as amended hereby.

         d.     Subsequent to the date hereof but prior to June 1998, Parent 
intends to issue capital stock through an initial public offering (the "Parent
IPO"), which may result in a change in the control of the Company of the type
restricted by Section 15(k) of the Loan Agreement.

         e.     The Company has requested that the Bank consent to the Parent 
IPO, and the Bank has agreed to give such consent upon the terms and conditions
of this Amendment and the terms and conditions of the Loan Agreement, as amended
hereby.

         f.     The Company has also advised the Bank that Events of Default 
have occurred under Subsection 17(d) of the Loan Agreement as a result of the
Company's failure to comply with the


FIRST AMENDMENT TO FOURTH AMENDED AND RESTATED LOAN AGREEMENT - Page 1

covenants set forth in (i) Subsection 16(a) of the Loan Agreement as of October
31, 1997, November 30, 1997 and December 31, 1997; (ii) Subsection 16(b) of the
Loan Agreement as of September 30, 1997, October 31, 1997, November 30, 1997,
December 31, 1997, and January 31, 1998; (iii) Subsections 14(a) through (e) of
the Loan Agreement for periods prior to the date hereof; and (iv) Subsection
15(d) of the Loan Agreement, which prohibits the Company's making any
acquisition for consideration in excess of $500,000, due to the acquisitions
made by the Company in 1997 (the Events of Default described above are herein
collectively called the "Existing Defaults", and the covenants in the
Subsections specifically described above, herein the "Violated Covenants").

         g.     The Company has requested that the Bank waive the Existing 
Defaults, and the Bank agrees to waive the Existing Defaults upon the terms and
conditions of this Amendment and the Loan Agreement, as amended hereby.


                                   AGREEMENT:

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

         1.     Waivers and Consents.

                  A.    The Bank hereby waives the Existing Defaults.

                  B.    The Bank hereby consents to the Company's departure from
         Subsection 15(k) of the Loan Agreement to the extent such covenant is
         violated by the Parent IPO.

                  C.    The Bank hereby waives the Company's compliance with the
         covenant set forth in Subsection 16(b) of the Loan Agreement from the

                        (a)     Subject to, and upon the terms, conditions,
                covenants and agreements contained herein, the Bank agrees to
                loan the Company, at any time, and from time to time prior to

                conjunction with this Agreement, such amounts as the Company may
                request up to but not exceeding an aggregate principal sum at
                any time outstanding equal to $25,000,000 (the "Revolving Line
                of Credit"); within such limits and during such period, the
                Company may borrow, repay, and re-borrow hereunder. All loans
                under the Revolving Line of Credit shall be evidenced by the
                Company's Renewal Master Revolving Credit Note dated March 27,

                and payable as set forth on the face of the Revolving Note.
                Notation by the Bank on its records shall constitute prima facie
                evidence of the amount and date of any payment or borrowing
                thereunder. The Revolving Line of Credit shall be used by the
                Company for its ordinary working capital needs, or for general
                corporate purposes, or for its (or Parent's, in the case of the
                Condor Acquisition only, as such term is defined in the First
                Amendment to this Agreement) acquisition of all or substantially
                all of the assets or capital stock of one or more operating
                businesses (each such acquisition a "Revolver Acquisition").

                B.  Subsection 16(a) is amended in its entirety to read
         as follows:

                        (a) Working Capital. Maintain at all times Working
                Capital in an amount not less than $12,000,000. "Working
                Capital" is defined as current assets less current liabilities,
                with the exception that current assets will exclude prepaid
                assets other than prepaid catalog expenses and current
                liabilities shall at all times exclude amounts outstanding under
                the Revolving Line of Credit.

                C.  Exhibits A, B-1 and B-2 are amended in their entireties

                   owned or hereafter acquired, in and to the property described
                   below: (give description)

         The term "Collateral" as used in this Agreement shall mean and include,
and the security interest (and pledge and assignment as applicable) shall cover,
all of the foregoing property, as well as any accessions, additions and
attachments thereto and the proceeds and products thereof, including without
limitation, all cash, general intangibles, accounts, inventory, equipment,
fixtures, farm products, notes, drafts, acceptances, securities, instruments,
chattel paper, insurance proceeds payable because of loss or damage, or other
property, benefits or rights arising therefrom, and in and to all returned or
repossessed goods arising from or relating to any of the property described
herein or other proceeds of any sale or other disposition of such property.

         As additional security for the punctual payment and performance of the
Obligations, and as part of the Collateral, Debtor hereby grants to Secured
Party a security interest in, and a pledge and assignment of, any and all money,
property, deposit accounts, accounts, securities, documents, chattel paper,
claims, demands, instruments, items or deposits of the Debtor, and each of them,
or to which any of them is a party, now held or hereafter coming within Secured
Party's custody or control, including, without limitation, all certificates of
deposit and other depository accounts, whether such have matured or the exercise
of Secured Party's rights results in loss of interest or principal or other
penalty on such deposits, but excluding deposits subject to tax penalties if
assigned. Without prior notice to or demand upon the Debtor, Secured Party may
exercise its rights granted above at any time when a default has occurred or
Secured Party deems itself insecure. Secured Party's rights and remedies under
this paragraph shall be in addition to and cumulative of any other rights or
remedies at law and equity, including, without limitation, any rights of set-off
to which Secured Party may be entitled.

                        to Secured Party concerning Debtor, the Collateral and

                   iv.       AUTHORITY.  Debtor has full right and authority to

                        performance by Debtor of this Agreement will not violate

                        or other agreement to which Debtor is a party, or by
                        which Debtor or any of Debtor's property is bound, or be
                        in conflict with, result in a breach of or constitute
                        (with due notice and/or lapse of time) a default under
                        any such indenture or other agreement, or result in the
                        creation or imposition of any charge, lien, security
                        interest, claim or encumbrance of any and every nature
                        whatsoever upon the Collateral, except as contemplated
                        by this Agreement.

                   v.        ADDRESSES. The address of Debtor designated at the
                        beginning of this Agreement is Debtor's place of
                        business if Debtor has only one place of business;
                        Debtor's chief executive office if Debtor has more than
                        one place of business; or Debtor's residence if Debtor
                        has no place of business. Debtor agrees not to change
                        such address without advance written notice to Secured
                        Party.

                        conformity with all applicable permits or licenses.
                        Debtor shall comply in all respects with all applicable
                        statutes, laws, ordinances and regulations. Debtor shall
                        not use the Collateral in any unlawful manner or for any
                        unlawful purposes, or in any manner or for any purpose
                        that would expose the Collateral to unusual risk, or to
                        penalty, forfeiture or capture, or that would render
                        inoperative any insurance in connection with the
                        Collateral.

                        all parts that may be worn out, lost, destroyed or
                        otherwise rendered unfit for use, with appropriate
                        replacement parts. Debtor shall obtain and maintain in
                        good standing at all times all applicable permits,

                   iv.       NO ENCUMBRANCES. Debtor agrees not to suffer or
                        permit any charge, lien, security interest, adverse
                        claim or encumbrance of any and every nature whatsoever
                        against the Collateral or any part thereof.

                   v.        NO REMOVAL. Except as otherwise provided in this
                        Agreement, Debtor shall not remove the Collateral from
                        the county or counties designated at the beginning of
                        this Agreement without Secured Party's prior written
                        consent.

                   vi.       NO TRANSFER. Except as otherwise provided in this
                        Agreement with respect to inventory, Debtor shall not,
                        without the prior written consent of Secured Party,
                        sell, assign, transfer, lease, charter, encumber,
                        hypothecate or dispose of the Collateral, or any part
                        thereof, or interest therein, or offer to do any of the
                        foregoing.

                   vii.      NOTICES AND REPORTS.  Debtor shall promptly notify
                        Secured Party in writing of any change in the name,
                        identity or structure of Debtor, any charge, lien,
                        security interest, claim or encumbrance asserted against
                        the Collateral, any litigation against Debtor or the
                        Collateral, any theft, loss, injury or similar incident
                        involving the Collateral, and any other material matter
                        adversely affecting Debtor or the Collateral. Debtor
                        shall furnish such other reports, information and data
                        regarding Debtor's financial condition and operations,

                        that is or may be located upon leased premises, such
                        landlord's waivers to be in such form and upon such
                        terms as are acceptable to Secured Party.

                   ix.       ADDITIONAL FILINGS. Debtor agrees to execute and
                        deliver such financing statement or statements, or
                        amendments thereof or supplements thereto, or other
                        documents as Secured Party may from time to time require
                        in order to comply with the Texas Uniform Commercial
                        Code (or other applicable state law of the jurisdiction
                        where any of the Collateral is located) and to preserve
                        and protect the Secured Party's rights to the
                        Collateral.

                   x.        PROTECTION OF COLLATERAL.  Secured Party, at its
                        option, whether before or after default, but without any
                        obligation whatsoever to do so, may (a) discharge taxes,
                        claims, charges, liens, security interests, assessments
                        or other encumbrances of any and every nature whatsoever
                        at any time levied, placed upon or asserted against the
                        Collateral, (b) place and pay for insurance on the
                        Collateral, including insurance that only protects
                        Secured Party's interest, (c) pay for the repair,
                        improvement, testing, maintenance and preservation of
                        the Collateral, (d) pay any filing, recording,
                        registration, licensing or certification fees or other
                        fees and charges related to the Collateral, or (e) take
                        any other action to preserve and protect the Collateral
                        and Secured Party's rights and remedies under this
                        Agreement as Secured Party may deem necessary or
                        appropriate. Debtor agrees that Secured Party shall have
                        no duty or obligation whatsoever to take any of the
                        foregoing action. Debtor agrees to promptly reimburse
                        Secured Party upon demand for any payment made or any
                        expense incurred by the Secured Party pursuant to this
                        authorization. These payments and expenditures, together
                        with interest thereon from date incurred until paid by
                        Debtor at the maximum contract rate allowed under
                        applicable laws, which Debtor agrees to pay, shall
                        constitute additional Obligations and shall be secured
                        by and entitled to the benefits of this Agreement.

                   xi.       INSPECTION. Debtor shall at all reasonable times
                        allow Secured Party by or through any of its officers,
                        agents, attorneys or accountants, to examine the
                        Collateral, wherever located, and to examine and make
                        extracts from Debtor's books and records.

                   xii.      FURTHER ASSURANCES. Debtor shall do, make, procure,
                        execute and deliver all such additional and further
                        acts, things, deeds, interests and assurances as Secured
                        Party may require from time to time to protect, assure
                        and enforce Secured Party's rights and remedies.

                   xiii.     INSURANCE.  Debtor shall have and maintain
                        insurance at all time with respect to all tangible
                        Collateral insuring against risks of fire (including
                        so-called extended coverage), theft and other risks as
                        Secured Party may require, containing such terms, in
                        such form and amounts and written by such companies as
                        may be satisfactory to Secured Party, all of such
                        insurance to contain loss payable clauses in favor of
                        Secured Party as its interest may appear. All policies
                        of insurance shall provide for ten (10) days' written
                        minimum cancellation notice to Secured Party and at the
                        request of Secured Party shall be delivered to and held
                        by it. Secured Party is hereby authorized to act as
                        attorney for Debtor in obtaining, adjusting, settling
                        and canceling such insurance and endorsing any drafts or
                        instruments. Secured Party shall be authorized to apply
                        the proceeds from any insurance to the Obligations
                        secured hereby whether or not such Obligations are then
                        due and payable. Debtor specifically authorizes Secured
                        Party to disclose information from the policies of
                        insurance to prospective insurers regarding the
                        Collateral.

                   xiv.      ADDITIONAL COLLATERAL.  If Secured Party should at
                        any time be of the opinion that the Collateral is
                        impaired, not sufficient or has declined or may decline
                        in value, or should Secured Party deem payment of the
                        Obligations to be insecure, then Secured Party may call
                        for additional security satisfactory to Secured Party,
                        and Debtor promises to furnish such additional security
                        forthwith. The call for additional security may be oral,
                        by telegram, or United States mail addressed to Debtor,
                        and shall not affect any other subsequent right of
                        Secured Party to exercise the same.

              f.        ADDITIONAL PROVISIONS REGARDING ACCOUNTS.  The following
                   provisions shall apply to all accounts included within the
                   Collateral:

                   i.        DEFINITIONS.  The term "account", as used in this
                        Agreement, shall have the same meaning as set forth in
                        the Uniform Commercial Code of Texas in effect as of the
                        date of execution hereof, and as set forth in any
                        amendment to the Uniform Commercial Code of Texas to
                        become effective after the date of execution hereof, and
                        also shall include all present and future notes,
                        instruments, documents, general intangibles, drafts,
                        acceptances and chattel paper of Debtor, and the
                        proceeds thereof.

                   ii.       ADDITIONAL WARRANTIES. As of the time any account
                        becomes subject to the security interest (or pledge of
                        assignment as applicable) granted hereby, Debtor shall
                        be deemed further to have


                                        7

<PAGE>   8

                        warranted as to each and all of such accounts as
                        follows: (a) each account and all papers and documents
                        relating thereto are genuine and in all respects what
                        they purport to be; (b) each account is valid and
                        subsisting and arises out of a bona fide sale of goods
                        sold and delivered to, or out of and for services
                        theretofore actually rendered by the Debtor to, the
                        account debtor named in the account; (c) the amount of
                        the account represented as owing is the correct amount
                        actually and unconditionally owing except for normal
                        cash discounts and is not subject to any set-offs,
                        credits, defenses or counter-charges; and (d) Debtor is
                        the owner thereof free and clear of any charges, liens,
                        security interests, adverse claims and encumbrances of
                        any and every nature whatsoever.

                   iii.      COLLECTION OF ACCOUNTS.  Secured Party shall have
                        the right in its own name or in the name of the Debtor,
                        whether before or after default, to require Debtor
                        forthwith to transmit all proceeds of collection of
                        accounts to Secured Party, to notify any and all account
                        debtors to make payments of the accounts directly to
                        Secured Party, to demand, collect, receive, receipt for,
                        sue for, compound and give acquittal for, any and all
                        amounts due or to become due on the accounts and to
                        endorse the name of the Debtor on all commercial paper
                        given in payment or part payment thereof, and in Secured
                        Party's discretion to file any claim or take any other
                        action or proceeding that Secured Party may deem
                        necessary or appropriate to protect and preserve and
                        realize upon the accounts and related Collateral. Unless
                        and until Secured Party elects to collect accounts, and
                        the privilege of Debtor to collect accounts is revoked
                        by Secured Party in writing, Debtor shall continue to
                        collect accounts, account for same to Secured Party, and
                        shall not commingle the proceeds of collection of
                        accounts with any funds of the Debtor. In order to
                        assure collection of accounts in which Secured Party has
                        a security interest (or pledge or assignment of as
                        applicable) hereunder, Secured Party may notify the post
                        office authorities to change the address for delivery of
                        mail addressed to Debtor to such address as Secured
                        Party may designate, and to open and dispose of such
                        mail and receive the collections of accounts included
                        herewith. Secured Party shall have no duty or obligation
                        whatsoever to collect any account, or to take any other
                        action to preserve or protect the Collateral; however,
                        should Secured Party elect to collect any account or
                        take possession of any Collateral, Debtor releases
                        Secured Party from any claim or claims for loss or
                        damage arising from any act or omission in connection
                        therewith.

                   iv.       IDENTIFICATION AND ASSIGNMENT OF ACCOUNTS. Upon
                        Secured Party's request, whether before or after
                        default, Debtor shall take

                        such action and execute and deliver such documents as
                        Secured Party may reasonably request in order to
                        identify, confirm, mark, segregate and assign accounts
                        and to evidence Secured Party's interest in same.
                        Without limitation of the foregoing, Debtor, upon
                        request, agrees to assign accounts to Secured Party,
                        identify and mark accounts as being subject to the
                        security interest (or pledge or assignment as
                        applicable) granted hereby, mark Debtor's books and
                        records to reflect such assignments, and forthwith to
                        transmit to Secured Party in the form as received by
                        Debtor any and all proceeds of collection of such
                        accounts.

                   v.        ACCOUNT REPORTS.  Upon Secured Party's request,
                        Debtor will deliver to Secured Party, prior to the tenth

                        Secured Party may request, a written report in form and
                        content satisfactory to Secured Party, showing a listing
                        and aging of accounts and such other information as
                        Secured Party may request from time to time. Debtor
                        shall immediately notify Secured Party of the assertion
                        by any account debtor of any set-off, defense or claim
                        regarding an account or any other matter adversely
                        affecting an account.

                   vi.       SEGREGATION OF RETURNED GOODS.  Returned or
                        repossessed goods arising from or relating to any
                        accounts included within the Collateral shall if
                        requested by Secured Party be held separate and apart
                        from any other property. Debtor shall as often as
                        requested by Secured Party, but not less often than
                        weekly even though no special request has been made,
                        report to Secured Party the appropriate identifying
                        information with respect to any such returned or
                        repossessed goods relating to accounts included in
                        assignments or identifications made pursuant hereto.

              g.        ADDITIONAL PROVISIONS REGARDING INVENTORY. The following
                   provisions shall apply to all inventory included within the
                   Collateral:

                   i.        INVENTORY REPORTS.  Upon request by Secured Party,
                        Debtor will deliver to Secured Party, prior to the tenth

                        of any matter adversely affecting the inventory,
                        including, without limitation, any event causing loss or
                        depreciation in the value of the inventory and the
                        amount of such possible loss or depreciation.

                   ii.       LOCATION OF INVENTORY.  Debtor will promptly notify
                        Secured Party in writing of any addition to, change in
                        or discontinuance of its place(s) of business as shown
                        in this agreement, the places at which inventory is
                        located as shown herein, the location of its chief
                        executive office and the location of the office where it

                        sale in the ordinary course of business does not include
                        a transfer in partial or total satisfaction of a debt.

                   iv.       ACCOUNTS AS PROCEEDS. All accounts that are
                        proceeds of the inventory included within the Collateral

                   COLLATERAL. The following provisions shall apply to all
                   securities and similar property included within the
                   Collateral:

                   i.        ADDITIONAL WARRANTIES.  As to each and all
                        securities and similar property included within the

                        compliance with applicable law concerning form, content

                        applicable laws and regulations.

                   ii.       DIVIDENDS AND PROCEEDS.  Any and all payments,
                        dividends, other distributions (including stock
                        redemption proceeds), or other securities in respect of

                        part of the Collateral. Debtor may retain ordinary cash
                        dividends unless and until Secured Party requests that
                        same be paid and delivered to Secured Party (which
                        Secured Party may request either before or after
                        default), but shall not pay or distribute any dividends
                        to its shareholders.

                   iii.      COLLECTIONS.  Secured Party shall have the right at
                        any time and from time to time (whether before or after
                        default) to notify and direct the issuer or obligor to
                        make all payments, dividends and distributions regarding

                        issuer and obligor making payment to Secured Party
                        hereunder shall be fully protected in relying on the
                        written statement of Secured Party that it then holds a
                        security interest which entitles it to receive such

                        payment shall be full acquittance therefor to the one
                        making such payment.

                   iv.       VOTING RIGHTS.  Upon default, or if Secured Party
                        deems itself insecure, Secured Party shall have the
                        right, at its discretion, to transfer to or register in
                        the name of Secured Party or any nominee of Secured
                        Party any of the Collateral, and/or to exercise any or
                        all voting rights as to any or all of the Collateral.
                        For such purposes, Debtor hereby names, constitutes and
                        appoints the President or any Vice President of Secured
                        Party as Debtor's proxy in the Debtor's name, place and
                        stead to vote any and all of the securities, as such
                        proxy may elect, for and in the name, place and stead of
                        Debtor, as to all matters coming before shareholders,
                        such proxy to be irrevocable and deemed coupled with an
                        interest. The rights, powers and authority of said proxy
                        shall remain in full force


                                       11

<PAGE>   12

                        and effect, and shall not be rescinded, revoked,
                        terminated, amended or otherwise modified, until all
                        Obligations have been fully satisfied.

                   v.        NO DUTY.  Secured Party shall never be liable for
                        its failure to give notice to Debtor of default in the
                        payment of or upon the Collateral. Secured Party shall
                        have no duty to fix or preserve rights against prior
                        parties to the Collateral and shall never be liable for
                        its failure to use diligence to collect any amount
                        payable in respect to the Collateral, but shall be
                        liable only to account to Debtor for what it may
                        actually collect or receive thereon. Without limiting
                        the foregoing, it is specifically understood and agreed
                        that Secured Party shall have no responsibility for
                        ascertaining any maturities, calls, conversions,
                        exchanges, offers, tenders, or similar matters relating
                        to any of the Collateral or for informing Debtor with
                        respect to any of such matters (irrespective of whether
                        Secured Party actually has, or may be deemed to have,
                        knowledge thereof). The foregoing provisions of this
                        paragraph shall be fully applicable to all securities or
                        similar property held in pledge hereunder, irrespective
                        of whether Secured Party may have exercised any right to
                        have such securities or similar property registered in
                        its name or in the name of a nominee.

                   vi.       FURTHER ASSURANCES. Debtor agrees to execute such
                        stock powers, endorse such instruments, or execute such
                        additional pledge agreements or other documents as may
                        be required by the Secured Party in order effectively to
                        grant to Secured Party the security interest in (and
                        pledge and assignment of) the Collateral and to enforce
                        and exercise Secured Party's rights regarding same.

                   vii.      SECURITIES LAWS.  Debtor hereby agrees to cooperate
                        fully with Secured Party in order to permit Secured
                        Party to sell, at foreclosure or other private sale, the
                        Collateral pledged hereunder. Specifically, Debtor
                        agrees to fully comply with the securities laws of the
                        United States and of the State of Texas and to take such
                        action as may be necessary to permit Secured Party to
                        sell or otherwise transfer the securities pledged
                        hereunder in compliance with such laws. Without limiting
                        the foregoing, Debtor, at its own expense, upon request
                        by Secured Party, agrees to effect and obtain such
                        registrations, filings, statements, rulings, consents,
                        and other matters as Secured Party may request.

                   viii.     POWER OF ATTORNEY. Debtor hereby makes, constitutes
                        and appoints Secured Party or its nominee, its true and
                        lawful attorney in fact and in its name, place, and
                        stead, and on its behalf, and for

                        its use and benefit to complete, execute and file with
                        the United States Securities and Exchange Commission one
                        or more notices of proposed sale of securities pursuant
                        to Rule 144 under the Securities Act of 1933 and/or any
                        similar filings or notices with any applicable state
                        agencies, and said attorney in fact shall have full
                        power and authority to do, take and perform all and
                        every act and thing whatsoever requisite, proper or
                        necessary to be done, in the exercise of the rights and
                        powers herein granted, as fully to all intents and
                        purposes as Debtor might or could do if personally
                        present. This power shall be irrevocable and deemed
                        coupled with an interest. The rights, powers and
                        authority of said attorney in fact herein granted shall
                        commence and be in full force and effect from the date
                        of this agreement, and such rights, powers and authority
                        shall remain in full force and effect, and this power of
                        attorney shall not be rescinded, revoked, terminated,
                        amended or otherwise modified, until all Obligations
                        have been fully satisfied.

                   ix.       PRIVATE SALES.  Because of the Securities Act of
                        1933, as amended, or any other laws or regulations,
                        there may be legal restrictions or limitations affecting
                        Secured Party in any attempts to dispose of certain
                        portions of the Collateral in the enforcement of its
                        rights and remedies hereunder. For these reasons Secured
                        Party is hereby authorized by Debtor, but not obligated,
                        in the event any default hereunder, to sell all or any
                        part of the Collateral at private sale, subject to
                        investment letter or in any other manner which will not
                        require the Collateral, or any part thereof, to be
                        registered in accordance with the securities Act of
                        1933, as amended, or the rules and regulations
                        promulgated thereunder, or any other law or regulation.
                        Secured Party is also hereby authorized by Debtor, but
                        not obligated, to take such actions, give such notices,
                        obtain such rulings and consents, and do such other
                        things as Secured Party may deem appropriate in the
                        event of a sale or disposition of any of the Collateral.
                        Debtor clearly understands that Secured Party may in its
                        discretion approach a restricted number of potential
                        purchasers and that a sale under such circumstances may
                        yield a lower price for the Collateral or any part or
                        parts thereof than would otherwise be obtainable if same
                        were registered and sold in the open market, and Debtor
                        agrees that such private sales shall constitute a
                        commercially reasonable method of disposing of the
                        Collateral.

              i.        ADDITIONAL PROVISIONS REGARDING CERTIFICATES OF DEPOSIT
                   AND SIMILAR COLLATERAL. The following provisions shall apply
                   to certificates of deposit and similar property included
                   within the Collateral:



                                       13

<PAGE>   14



                   i.        COLLECTION OF DEPOSITS. Debtor agrees that
                        Secured Party may, at any time (whether before or after
                        default) and in its sole discretion, surrender for
                        payment and obtain payment of any portion of the
                        Collateral, whether such have matured or the exercise of
                        Secured Party's rights results in loss of interest or
                        principal or other penalty on such deposits, and, in
                        connection therewith, cause payment to be made directly
                        to Secured Party.

                   ii.       NOTICE TO THIRD PARTY ISSUER.  With regard to any
                        certificates of deposit or similar Collateral for which
                        Secured Party is not the issuer, Debtor agrees to notify
                        the issuer or obligor of the interests hereby granted to
                        Secured Party and to obtain from such issuer or obligor
                        acknowledgement of the interests in favor of Secured
                        Party and the issuer's or obligor's agreement to waive
                        in favor of Secured Party any and all rights of set-off
                        or similar rights or remedies to which such issuer or
                        obligor may be entitled, and, in connection therewith,
                        to execute and cause the issuer or obligor to execute,
                        any and all acknowledgments, waivers and other
                        agreements in such form and upon such terms as Secured
                        Party may request.

                   iii.      PROCEEDS. Any and all replacement or renewal
                        certificates, instruments, or other benefits or proceeds
                        related to the Collateral that are received by Debtor
                        shall be held by Debtor in trust for Secured Party and
                        immediately delivered to Secured Party to be held as
                        part of the Collateral.

                   iv.       NO DUTY.  Secured Party shall never be liable for
                        its failure to give notice to Debtor of default in the
                        payment of or upon the Collateral. Secured Party shall
                        have no duty to fix or preserve rights against prior
                        parties to the Collateral and shall never be liable for
                        its failure to use diligence to collect any amount
                        payable in respect to the Collateral, but shall be
                        liable only to account to Debtor for what it may
                        actually collect or receive thereon. Without limiting
                        the foregoing, it is specifically understood and agreed
                        that Secured Party shall have no responsibility for
                        ascertaining any maturities or similar matters relating
                        to any of the Collateral or for informing Debtor with
                        respect to any of such matters (irrespective of whether
                        Secured Party actually has, or may be deemed to have,
                        knowledge thereof).

              j.        EVENTS OF DEFAULT. Debtor shall be in default hereunder
                   upon the happening of any of the following events or
                   conditions: (i) non-payment when due (whether by acceleration
                   of maturity or otherwise) of any payment of principal,
                   interest or other amount due on any Obligation;


                                       14

<PAGE>   15

                   (ii) the occurrence of any event which under the terms of any
                   evidence of indebtedness, indenture, loan agreement, security
                   agreement or similar instrument permits the acceleration of
                   maturity of any obligation of Debtor or BearCom, Inc.
                   (whether to Secured Party or to others); (iii) any
                   representation or warranty made by Debtor to Secured Party in
                   connection with this Agreement, the Collateral or the
                   Obligations, or in any statements or certificates, proves
                   incorrect in any material respect as of the date of the
                   making or the issuance thereof; (iv) default occurs in the
                   observance or performance of, or if Debtor fails to furnish
                   adequate evidence of performance of, any provision of this
                   Agreement or of any note, assignment, transfer, other
                   agreement, document or instrument delivered by Debtor to
                   Secured Party in connection with this Agreement, the
                   Collateral or the Obligations; (v) death, dissolution,
                   liquidation, termination of existence, insolvency, business
                   failure or winding-up of Debtor or any maker, endorser,
                   guarantor, surety or other party liable in any capacity for
                   any of the Obligations; (vi) the commission of an act of
                   bankruptcy by, or the application for appointment of a
                   receiver or any other legal custodian for any part of the
                   property of, assignment for the benefit of creditors by, or
                   the commencement of any proceedings under any bankruptcy,
                   arrangement, reorganization, insolvency or similar laws for
                   the relief of debtors by or against, the Debtor or any maker,
                   endorser, guarantor, surety or other party primarily or
                   secondarily liable for any of the Obligations; (vii) the
                   Collateral becomes, in the judgment of Secured Party,
                   impaired, unsatisfactory or insufficient in character or
                   value; or (viii) the filing of any levy, attachment,
                   execution, garnishment or other process against the Debtor or
                   any of the Collateral or any maker, endorser, guarantor,
                   surety, or other party liable in any capacity for any of the
                   Obligations.

              k.        REMEDIES. Upon the occurrence of an event of default,
                   or if Secured Party deems payment of the Obligations to be
                   insecure, Secured Party, at its option, shall be entitled to
                   exercise any one or more of the following remedies (all of
                   which are cumulative):

                   i.        DECLARE OBLIGATIONS DUE. Secured Party, at its
                        option, may declare the Obligations or any part thereof
                        immediately due and payable, without demand, notice of
                        intention to accelerate, notice of acceleration, notice
                        of non-payment, presentment, protest, notice of
                        dishonor, or any other notice whatsoever, all of which
                        are hereby waived by Debtor and any maker, endorser,
                        guarantor, surety or other party liable in any capacity
                        for any of the Obligations.

                   ii.       REMEDIES. Secured Party shall have all of the
                        rights and remedies provided for in this Agreement and
                        in any other agreements executed by Debtor, the rights
                        and remedies of the Uniform Commercial Code of Texas,
                        and any and all of the rights


                                       15

<PAGE>   16

                        and remedies at law and in equity, all of which shall
                        be. deemed cumulative. Without limiting the foregoing,
                        Debtor agrees that Secured Party shall have the right
                        to: (a) require Debtor to assemble the Collateral and
                        make it available to Secured Party at a place designated
                        by Secured Party that is reasonably convenient to both '
                        parties, which Debtor agrees to do; (b) peaceably take
                        possession of the Collateral and remove same, with or
                        without judicial process; (c) without removal, render
                        equipment included within the Collateral unusable, and
                        dispose of the Collateral on the Debtor's premises; (d)
                        sell, lease or otherwise dispose of the Collateral, at
                        one or more locations, by public or private proceedings,
                        for cash or credit, without assumption of credit risk;
                        and/or (e) whether before or after default, collect and
                        receipt for, compound, compromise, and settle, and give
                        releases, discharges and acquittances with respect to,
                        any and all amounts owed by any person or entity with
                        respect to the Collateral. Unless the Collateral is
                        perishable or threatens to decline speedily in value or
                        is of a type customarily sold on a recognized market,
                        Secured Party will send Debtor reasonable notice of the
                        time and place of any public sale or of the time after
                        which any private sale or other disposition will be
                        made. Any requirement of reasonable notice to Debtor
                        shall be met if such notice is mailed, postage prepaid,
                        to Debtor at the address of Debtor designated at the
                        beginning of this Agreement, at least five (5) days
                        before the day of any public sale or at least five (5)
                        days before the time after which any private sale or
                        other disposition will be made.

                   iii.      EXPENSES.  Debtor shall be liable for and agrees to
                        pay the reasonable expenses incurred by Secured Party in
                        enforcing its rights and remedies, in retaking, holding,
                        testing, repairing, improving, selling, leasing or
                        disposing of the Collateral, or like expenses,
                        including, without limitation, attorneys' fees and legal
                        expenses incurred by Secured Party. These expenses,
                        together with interest thereon from date incurred until
                        paid by Debtor at the maximum contract rate allowed
                        under applicable laws, which Debtor agrees to pay, shall
                        constitute additional Obligations and shall be secured
                        by and entitled to the benefits of this Agreement.

                   iv.       PROCEEDS; SURPLUS; DEFICIENCIES. Proceeds received
                        by Secured Party from disposition of the Collateral
                        shall be applied toward Secured Party's expenses and
                        other Obligations in such order or manner as Secured
                        Party may elect. Debtor shall be entitled to any surplus
                        if one results after lawful application of the proceeds.

                   v.        REMEDIES CUMULATIVE. The rights and remedies of
                        Secured Party are cumulative and the exercise of any one
                        or more of the rights or remedies shall not be deemed an
                        election of rights or remedies or a waiver of any other
                        right or remedy. Secured Party may remedy any default
                        and may waive any default without waiving the default
                        remedied or without waiving any other prior or
                        subsequent default.

              l.        OTHER AGREEMENTS.

                   i.        SAVINGS CLAUSE.  Notwithstanding any provision to
                        the contrary herein, or in any of the documents
                        evidencing the Obligations or otherwise relating
                        thereto, no such provision shall require the payment or
                        permit the collection of interest in excess of the
                        maximum permitted by applicable usury laws. If any such
                        excessive interest is so provided for, then in such
                        event (i) the provisions of this paragraph shall govern
                        and control, (ii) neither the Debtor nor his heirs,
                        legal representatives, successors or assigns or any
                        other party liable for the payment thereof, shall be
                        obligated to pay the amount of such interest to the
                        extent that is in excess of the maximum amount permitted
                        by law, (iii) any such excess interest that may have
                        been collected shall be, at the option of the holder of
                        the instrument evidencing the Obligations, either
                        applied as a credit against the then unpaid principal
                        amount thereof or refunded to the maker thereof, and
                        (iv) the effective rate of interest shall be
                        automatically reduced to the maximum lawful rate under
                        applicable usury laws as now or hereafter construed by
                        the courts having jurisdiction.

                   ii.       JOINT AND SEVERAL RESPONSIBILITY. If this Security
                        Agreement is executed by more than one Debtor, the
                        obligations of all such Debtors shall be joint and
                        several.

                   iii.      WAIVERS. Debtor and any maker, endorser, guarantor,
                        surety or other party liable in any capacity respecting
                        the Obligations hereby waive demand, notice of intention
                        to accelerate, notice of acceleration, notice of
                        non-payment, presentment, protest, notice of dishonor
                        and any other similar notice whatsoever.

                   iv.       SEVERABILITY. Any provision hereof found to be
                        invalid by courts having jurisdiction shall be invalid
                        only with respect to such provision (and then only to
                        the extent necessary to avoid such invalidity). The
                        offending provision shall be modified to the maximum
                        extent possible to confer upon Secured Party the
                        benefits intended thereby. Such provision as modified
                        and the remaining


                                       17

<PAGE>   18

                        provisions hereof shall be construed and enforced to the
                        same effect as if such offending provision (or portion
                        thereof) had not been contained herein, to the maximum
                        extent possible.

                   v.        USE OF COPIES. Any carbon, photographic or other
                        reproduction of any financing statement signed by Debtor
                        is sufficient as a financing statement for all purposes,
                        including without limitation, filing in any state as may
                        be permitted by the provisions of the Uniform Commercial
                        Code of such state.

                   vi.       RELATIONSHIP TO OTHER AGREEMENTS.  This Security
                        Agreement and the security interests (and pledges and
                        assignments as applicable) herein granted are in
                        addition to (and not in substitution, novation or

                        security agreements, security interests, pledges,
                        assignments, liens, rights, titles or other interests in
                        favor of Secured Party or assigned to Secured Party by
                        others in connection with the Obligations. All rights
                        and remedies of Secured Party in all such agreements are
                        cumulative, but in the event of actual conflict in terms
                        and conditions, the terms and conditions of the latest
                        security agreement shall govern and control.

                   vii.      NOTICES. Any notice or demand given by Secured
                        Party to Debtor in connection with this Agreement, the
                        Collateral or the Obligations, shall be deemed given and

                        gender or number as the circumstances require.

                        provisions may be changed, amended, modified, waived or
                        discharged orally, but only by an instrument in writing

                        change, amendment, modification, waiver or discharge is
                        sought.

                        interest, claim or encumbrance of any and every nature
                        whatsoever upon the Collateral, except as contemplated

                        penalty, forfeiture or capture, or that would render
                        inoperative any insurance in connection with the

                        this Agreement without Secured Party's prior written
                        consent.

                   vi.       NO TRANSFER. Except as otherwise provided in this
                        Agreement with respect to inventory, Debtor shall not,

                        Collateral, any theft, loss, injury or similar incident
                        involving the Collateral, and any other material matter
                        adversely affecting Debtor or the Collateral. Debtor
                        shall furnish such other reports, information and data

                   ix.       ADDITIONAL FILINGS. Debtor agrees to execute and
                        deliver such financing statement or statements, or
                        amendments thereof or supplements thereto, or other
                        documents as Secured Party may from time to time require
                        in order to comply with the Texas Uniform Commercial
                        Code (or other applicable state law of the jurisdiction
                        where any of the Collateral is located) and to preserve
                        and protect the Secured Party's rights to the
                        Collateral.

                   x.        PROTECTION OF COLLATERAL.  Secured Party, at its
                        option, whether before or after default, but without any
                        obligation whatsoever to do so, may (a) discharge taxes,
                        claims, charges, liens, security interests, assessments
                        or other encumbrances of any and every nature whatsoever
                        at any time levied, placed upon or asserted against the
                        Collateral, (b) place and pay for insurance on the
                        Collateral, including insurance that only protects
                        Secured Party's interest, (c) pay for the repair,
                        improvement, testing, maintenance and preservation of
                        the Collateral, (d) pay any filing, recording,
                        registration, licensing or certification fees or other
                        fees and charges related to the Collateral, or (e) take
                        any other action to preserve and protect the Collateral
                        and Secured Party's rights and remedies under this
                        Agreement as Secured Party may deem necessary or
                        appropriate. Debtor agrees that Secured Party shall have
                        no duty or obligation whatsoever to take any of the
                        foregoing action. Debtor agrees to promptly reimburse
                        Secured Party upon demand for any payment made or any
                        expense incurred by the Secured Party pursuant to this
                        authorization. These payments and expenditures, together
                        with interest thereon from date incurred until paid by
                        Debtor at the maximum contract rate allowed under
                        applicable laws, which Debtor agrees to pay, shall
                        constitute additional Obligations and shall be secured
                        by and entitled to the benefits of this Agreement.

                   xi.       INSPECTION. Debtor shall at all reasonable times
                        allow Secured Party by or through any of its officers,
                        agents, attorneys or accountants, to examine the
                        Collateral, wherever located, and to examine and make
                        extracts from Debtor's books and records.

                   xii.     FURTHER ASSURANCES. Debtor shall do, make, procure,
                        execute and deliver all such additional and further
                        acts, things, deeds, interests and assurances as Secured
                        Party may require from time to time to protect, assure
                        and enforce Secured Party's rights and remedies.

                   xiii.     INSURANCE.  Debtor shall have and maintain
                        insurance at all time with respect to all tangible
                        Collateral insuring against risks of fire (including
                        so-called extended coverage), theft and other risks as
                        Secured Party may require, containing such terms, in
                        such form and amounts and written by such companies as
                        may be satisfactory to Secured Party, all of such
                        insurance to contain loss payable clauses in favor of
                        Secured Party as its interest may appear. All policies
                        of insurance shall provide for ten (10) days' written
                        minimum cancellation notice to Secured Party and at the
                        request of Secured Party shall be delivered to and held
                        by it. Secured Party is hereby authorized to act as
                        attorney for Debtor in obtaining, adjusting, settling
                        and canceling such insurance and endorsing any drafts or
                        instruments. Secured Party shall be authorized to apply
                        the proceeds from any insurance to the Obligations
                        secured hereby whether or not such Obligations are then
                        due and payable. Debtor specifically authorizes Secured
                        Party to disclose information from the policies of
                        insurance to prospective insurers regarding the
                        Collateral.

                   xiv.      ADDITIONAL COLLATERAL.  If Secured Party should at
                        any time be of the opinion that the Collateral is
                        impaired, not sufficient or has declined or may decline
                        in value, or should Secured Party deem payment of the
                        Obligations to be insecure, then Secured Party may call
                        for additional security satisfactory to Secured Party,
                        and Debtor promises to furnish such additional security
                        forthwith. The call for additional security may be oral,
                        by telegram, or United States mail addressed to Debtor,
                        and shall not affect any other subsequent right of
                        Secured Party to exercise the same.

              f.        ADDITIONAL PROVISIONS REGARDING ACCOUNTS.  The following
                   provisions shall apply to all accounts included within the
                   Collateral:

                   i.        DEFINITIONS.  The term "account", as used in this
                        Agreement, shall have the same meaning as set forth in
                        the Uniform Commercial Code of Texas in effect as of the
                        date of execution hereof, and as set forth in any
                        amendment to the Uniform Commercial Code of Texas to
                        become effective after the date of execution hereof, and
                        also shall include all present and future notes,
                        instruments, documents, general intangibles, drafts,
                        acceptances and chattel paper of Debtor, and the
                        proceeds thereof.

                   ii.       ADDITIONAL WARRANTIES. As of the time any account
                        becomes subject to the security interest (or pledge of
                        assignment as applicable) granted hereby, Debtor shall
                        be deemed further to have


                                        7

<PAGE>   8

                        warranted as to each and all of such accounts as
                        follows: (a) each account and all papers and documents
                        relating thereto are genuine and in all respects what
                        they purport to be; (b) each account is valid and
                        subsisting and arises out of a bona fide sale of goods
                        sold and delivered to, or out of and for services
                        theretofore actually rendered by the Debtor to, the
                        account debtor named in the account; (c) the amount of
                        the account represented as owing is the correct amount
                        actually and unconditionally owing except for normal
                        cash discounts and is not subject to any set-offs,
                        credits, defenses or counter-charges; and (d) Debtor is
                        the owner thereof free and clear of any charges, liens,
                        security interests, adverse claims and encumbrances of
                        any and every nature whatsoever.

                   iii.      COLLECTION OF ACCOUNTS.  Secured Party shall have
                        the right in its own name or in the name of the Debtor,
                        whether before or after default, to require Debtor
                        forthwith to transmit all proceeds of collection of
                        accounts to Secured Party, to notify any and all account
                        debtors to make payments of the accounts directly to
                        Secured Party, to demand, collect, receive, receipt for,
                        sue for, compound and give acquittal for, any and all
                        amounts due or to become due on the accounts and to
                        endorse the name of the Debtor on all commercial paper
                        given in payment or part payment thereof, and in Secured
                        Party's discretion to file any claim or take any other
                        action or proceeding that Secured Party may deem
                        necessary or appropriate to protect and preserve and
                        realize upon the accounts and related Collateral. Unless
                        and until Secured Party elects to collect accounts, and
                        the privilege of Debtor to collect accounts is revoked
                        by Secured Party in writing, Debtor shall continue to
                        collect accounts, account for same to Secured Party, and
                        shall not commingle the proceeds of collection of
                        accounts with any funds of the Debtor. In order to
                        assure collection of accounts in which Secured Party has
                        a security interest (or pledge or assignment of as
                        applicable) hereunder, Secured Party may notify the post
                        office authorities to change the address for delivery of
                        mail addressed to Debtor to such address as Secured
                        Party may designate, and to open and dispose of such
                        mail and receive the collections of accounts included
                        herewith. Secured Party shall have no duty or obligation
                        whatsoever to collect any account, or to take any other
                        action to preserve or protect the Collateral; however,
                        should Secured Party elect to collect any account or
                        take possession of any Collateral, Debtor releases
                        Secured Party from any claim or claims for loss or
                        damage arising from any act or omission in connection
                        therewith.

                   iv.       IDENTIFICATION AND ASSIGNMENT OF ACCOUNTS. Upon
                        Secured Party's request, whether before or after
                        default, Debtor shall take

                        Secured Party may reasonably request in order to
                        identify, confirm, mark, segregate and assign accounts
                        and to evidence Secured Party's interest in same.
                        Without limitation of the foregoing, Debtor, upon
                        request, agrees to assign accounts to Secured Party,
                        identify and mark accounts as being subject to the
                        security interest (or pledge or assignment as
                        applicable) granted hereby, mark Debtor's books and
                        records to reflect such assignments, and forthwith to
                        transmit to Secured Party in the form as received by

                        accounts.

                   v.        ACCOUNT REPORTS.  Upon Secured Party's request,

                        Secured Party may request from time to time. Debtor
                        shall immediately notify Secured Party of the assertion
                        by any account debtor of any set-off, defense or claim
                        regarding an account or any other matter adversely
                        affecting an account.

                   vi.       SEGREGATION OF RETURNED GOODS.  Returned or
                        repossessed goods arising from or relating to any

                        requested by Secured Party be held separate and apart
                        from any other property. Debtor shall as often as
                        requested by Secured Party, but not less often than

                        report to Secured Party the appropriate identifying
                        information with respect to any such returned or

                   provisions shall apply to all inventory included within the
                   Collateral:

                        including, without limitation, any event causing loss or
                        depreciation in the value of the inventory and the
                        amount of such possible loss or depreciation.

                   ii.       LOCATION OF INVENTORY.  Debtor will promptly notify

                        in this agreement, the places at which inventory is
                        located as shown herein, the location of its chief

                        event of default or if Secured Party deems itself
                        insecure, Debtor may use the inventory in any manner not

                        are necessary in order to carry on Debtor's business. A
                        sale in the ordinary course of business does not include
                        a transfer in partial or total satisfaction of a debt.

                   iv.       ACCOUNTS AS PROCEEDS. All accounts that are
                        proceeds of the inventory included within the Collateral

                   COLLATERAL. The following provisions shall apply to all
                   securities and similar property included within the
                   Collateral:

                   i.        ADDITIONAL WARRANTIES.  As to each and all
                        securities and similar property included within the

                        are part of the Collateral), Debtor further represents
                        and warrants, as of the time of. delivery of same to

                        nonassessable, and are not issued in violation of the
                        preemptive rights of any person or of any agreement by

                        right of any third person; (c) such securities are in
                        compliance with applicable law concerning form, content
                        and manner of preparation and execution; and (d) Debtor
                        acquired and holds the securities in compliance with all
                        applicable laws and regulations.

                   ii.       DIVIDENDS AND PROCEEDS.  Any and all payments,
                        dividends, other distributions (including stock

                        part of the Collateral. Debtor may retain ordinary cash
                        dividends unless and until Secured Party requests that
                        same be paid and delivered to Secured Party (which
                        Secured Party may request either before or after
                        default).

                   iii.      COLLECTIONS.  Secured Party shall have the right at
                        any time and from time to time (whether before or after
                        default) to notify and direct the issuer or obligor to
                        make all payments, dividends and distributions regarding
                        the Collateral directly to Secured Party. Secured Party

                        issuer and obligor making payment to Secured Party
                        hereunder shall be fully protected in relying on the
                        written statement of Secured Party that it then holds a
                        security interest which entitles it to receive such
                        payment, and the receipt by Secured Party for such
                        payment shall be full acquittance therefor to the one
                        making such payment.

                   iv.       VOTING RIGHTS.  Upon default, or if Secured Party
                        deems itself insecure, Secured Party shall have the

                        the name of Secured Party or any nominee of Secured
                        Party any of the Collateral, and/or to exercise any or
                        all voting rights as to any or all of the Collateral.
                        For such purposes, Debtor hereby names, constitutes and
                        appoints the President or any Vice President of Secured
                        Party as Debtor's proxy in the Debtor's name, place and
                        stead to vote any and all of the securities, as such
                        proxy may elect, for and in the name, place and stead of
                        Debtor, as to all matters coming before shareholders,
                        such proxy to be irrevocable and deemed coupled with an
                        interest. The rights, powers and authority of said proxy
                        shall remain in full force and effect, and shall not be
                        rescinded, revoked, terminated,

                        amended or otherwise modified, until all Obligations
                        have been fully satisfied.

                   v.        NO DUTY.  Secured Party shall never be liable for
                        its failure to give notice to Debtor of default in the
                        payment of or upon the Collateral. Secured Party shall
                        have no duty to fix or preserve rights against prior
                        parties to the Collateral and shall never be liable for
                        its failure to use diligence to collect any amount
                        payable in respect to the Collateral, but shall be
                        liable only to account to Debtor for what it may
                        actually collect or receive thereon. Without limiting
                        the foregoing, it is specifically understood and agreed
                        that Secured Party shall have no responsibility for
                        ascertaining any maturities, calls, conversions,
                        exchanges, offers, tenders, or similar matters relating
                        to any of the Collateral or for informing Debtor with
                        respect to any of such matters (irrespective of whether
                        Secured Party actually has, or may be deemed to have,
                        knowledge thereof). The foregoing provisions of this
                        paragraph shall be fully applicable to all securities or
                        similar property held in pledge hereunder, irrespective
                        of whether Secured Party may have exercised any right to
                        have such securities or similar property registered in
                        its name or in the name of a nominee.

                   vi.       FURTHER ASSURANCES. Debtor agrees to execute such
                        stock powers, endorse such instruments, or execute such
                        additional pledge agreements or other documents as may
                        be required by the Secured Party in order effectively to
                        grant to Secured Party the security interest in (and
                        pledge and assignment of) the Collateral and to enforce
                        and exercise Secured Party's rights regarding same.

                   vii.      SECURITIES LAWS.  Debtor hereby agrees to cooperate
                        fully with Secured Party in order to permit Secured
                        Party to sell, at foreclosure or other private sale, the
                        Collateral pledged hereunder. Specifically, Debtor
                        agrees to fully comply with the securities laws of the
                        United States and of the State of Texas and to take such
                        action as may be necessary to permit Secured Party to
                        sell or otherwise transfer the securities pledged
                        hereunder in compliance with such laws. Without limiting
                        the foregoing, Debtor, at its own expense, upon request
                        by Secured Party, agrees to effect and obtain such
                        registrations, filings, statements, rulings, consents,
                        and other matters as Secured Party may request.

                   viii.     POWER OF ATTORNEY. Debtor hereby makes, constitutes
                        and appoints Secured Party or its nominee, its true and
                        lawful attorney in fact and in its name, place, and
                        stead, and on its behalf, and for its use and benefit to
                        complete, execute and file with the United


                                       12

                        States Securities and Exchange Commission one or more
                        notices of proposed sale of securities pursuant to Rule
                        144 under the Securities Act of 1933 and/or any similar
                        filings or notices with any applicable state agencies,
                        and said attorney in fact shall have full power and
                        authority to do, take and perform all and every act and
                        thing whatsoever requisite, proper or necessary to be
                        done, in the exercise of the rights and powers herein
                        granted, as fully to all intents and purposes as Debtor
                        might or could do if personally present. This power
                        shall be irrevocable and deemed coupled with an
                        interest. The rights, powers and authority of said
                        attorney in fact herein granted shall commence and be in
                        full force and effect from the date of this agreement,
                        and such rights, powers and authority shall remain in
                        full force and effect, and this power of attorney shall
                        not be rescinded, revoked, terminated, amended or
                        otherwise modified, until all Obligations have been
                        fully satisfied.

                   ix.       PRIVATE SALES.  Because of the Securities Act of
                        1933, as amended, or any other laws or regulations,
                        there may be legal restrictions or limitations affecting
                        Secured Party in any attempts to dispose of certain
                        portions of the Collateral in the enforcement of its
                        rights and remedies hereunder. For these reasons Secured
                        Party is hereby authorized by Debtor, but not obligated,
                        in the event any default hereunder, to sell all or any
                        part of the Collateral at private sale, subject to
                        investment letter or in any other manner which will not
                        require the Collateral, or any part thereof, to be
                        registered in accordance with the securities Act of
                        1933, as amended, or the rules and regulations
                        promulgated thereunder, or any other law or regulation.
                        Secured Party is also hereby authorized by Debtor, but
                        not obligated, to take such actions, give such notices,
                        obtain such rulings and consents, and do such other
                        things as Secured Party may deem appropriate in the
                        event of a sale or disposition of any of the Collateral.
                        Debtor clearly understands that Secured Party may in its
                        discretion approach a restricted number of potential
                        purchasers and that a sale under such circumstances may
                        yield a lower price for the Collateral or any part or
                        parts thereof than would otherwise be obtainable if same
                        were registered and sold in the open market, and Debtor
                        agrees that such private sales shall constitute a
                        commercially reasonable method of disposing of the
                        Collateral.

              i.        ADDITIONAL PROVISIONS REGARDING CERTIFICATES OF DEPOSIT
                   AND SIMILAR COLLATERAL. The following provisions shall apply
                   to certificates of deposit and similar property included
                   within the Collateral:



                                       13

<PAGE>   14

                   i.        COLLECTION OF DEPOSITS. Debtor agrees that Secured
                        Party may, at any time (whether before or after default)
                        and in its sole discretion, surrender for payment and
                        obtain payment of any portion of the Collateral, whether
                        such have matured or the exercise of Secured Party's
                        rights results in loss of interest or principal or other
                        penalty on such deposits, and, in connection therewith,
                        cause payment to be made directly to Secured Party.

                   ii.       NOTICE TO THIRD PARTY ISSUER.  With regard to any
                        certificates of deposit or similar Collateral for which
                        Secured Party is not the issuer, Debtor agrees to notify
                        the issuer or obligor of the interests hereby granted to
                        Secured Party and to obtain from such issuer or obligor
                        acknowledgement of the interests in favor of Secured
                        Party and the issuer's or obligor's agreement to waive
                        in favor of Secured Party any and all rights of set-off
                        or similar rights or remedies to which such issuer or
                        obligor may be entitled, and, in connection therewith,
                        to execute and cause the issuer or obligor to execute,
                        any and all acknowledgments, waivers and other
                        agreements in such form and upon such terms as Secured
                        Party may request.

                   iii.      PROCEEDS. Any and all replacement or renewal
                        certificates, instruments, or other benefits or proceeds
                        related to the Collateral that are received by Debtor
                        shall be held by Debtor in trust for Secured Party and
                        immediately delivered to Secured Party to be held as
                        part of the Collateral.

                   iv.       NO DUTY.  Secured Party shall never be liable for
                        its failure to give notice to Debtor of default in the
                        payment of or upon the Collateral. Secured Party shall
                        have no duty to fix or preserve rights against prior
                        parties to the Collateral and shall never be liable for
                        its failure to use diligence to collect any amount
                        payable in respect to the Collateral, but shall be
                        liable only to account to Debtor for what it may
                        actually collect or receive thereon. Without limiting
                        the foregoing, it is specifically understood and agreed
                        that Secured Party shall have no responsibility for
                        ascertaining any maturities or similar matters relating
                        to any of the Collateral or for informing Debtor with
                        respect to any of such matters (irrespective of whether
                        Secured Party actually has, or may be deemed to have,
                        knowledge thereof).

              j.        EVENTS OF DEFAULT. Debtor shall be in default hereunder
                   upon the happening of any of the following events or
                   conditions: (i) non-payment when due (whether by acceleration
                   of maturity or otherwise) of any payment of principal,
                   interest or other amount due on any Obligation;


                                       14

<PAGE>   15



                   (ii) the occurrence of any event which under the terms of any
                   evidence of indebtedness, indenture, loan agreement, security
                   agreement or similar instrument permits the acceleration of
                   maturity of any obligation of Debtor or BearCom, Inc.
                   (whether to Secured Party or to others); (iii) any
                   representation or warranty made by Debtor to Secured Party in
                   connection with this Agreement, the Collateral or the
                   Obligations, or in any statements or certificates, proves
                   incorrect in any material respect as of the date of the
                   making or the issuance thereof; (iv) default occurs in the
                   observance or performance of, or if Debtor fails to furnish
                   adequate evidence of performance of, any provision of this
                   Agreement or of any note, assignment, transfer, other
                   agreement, document or instrument delivered by Debtor to
                   Secured Party in connection with this Agreement, the
                   Collateral or the Obligations; (v) death, dissolution,
                   liquidation, termination of existence, insolvency, business
                   failure or winding-up of Debtor or any maker, endorser,
                   guarantor, surety or other party liable in any capacity for
                   any of the Obligations; (vi) the commission of an act of
                   bankruptcy by, or the application for appointment of a
                   receiver or any other legal custodian for any part of the
                   property of, assignment for the benefit of creditors by, or
                   the commencement of any proceedings under any bankruptcy,
                   arrangement, reorganization, insolvency or similar laws for
                   the relief of debtors by or against, the Debtor or any maker,
                   endorser, guarantor, surety or other party primarily or
                   secondarily liable for any of the Obligations; (vii) the
                   Collateral becomes, in the judgment of Secured Party,
                   impaired, unsatisfactory or insufficient in character or
                   value; or (viii) the filing of any levy, attachment,
                   execution, garnishment or other process against the Debtor or
                   any of the Collateral or any maker, endorser, guarantor,
                   surety, or other party liable in any capacity for any of the
                   Obligations.

              k.        REMEDIES. Upon the occurrence of an event of default, or
                   if Secured Party deems payment of the Obligations to be
                   insecure, Secured Party, at its option, shall be entitled to
                   exercise any one or more of the following remedies (all of
                   which are cumulative):

                   i.        DECLARE OBLIGATIONS DUE. Secured Party, at its
                        option, may declare the Obligations or any part thereof
                        immediately due and payable, without demand, notice of
                        intention to accelerate, notice of acceleration, notice
                        of non-payment, presentment, protest, notice of
                        dishonor, or any other notice whatsoever, all of which
                        are hereby waived by Debtor and any maker, endorser,
                        guarantor, surety or other party liable in any capacity
                        for any of the Obligations.

                   ii.       REMEDIES. Secured Party shall have all of the
                        rights and remedies provided for in this Agreement and
                        in any other agreements executed by Debtor, the rights
                        and remedies of the Uniform Commercial Code of Texas,
                        and any and all of the rights


                                       15

<PAGE>   16



                        and remedies at law and in equity, all of which shall be
                        deemed cumulative. Without limiting the foregoing,
                        Debtor agrees that Secured Party shall have the right
                        to: (a) require Debtor to assemble the Collateral and
                        make it available to Secured Party at a place designated
                        by Secured Party that is reasonably convenient to both
                        parties, which Debtor agrees to do; (b) peaceably take
                        possession of the Collateral and remove same, with or
                        without judicial process; (c) without removal, render
                        equipment included within the Collateral unusable, and
                        dispose of the Collateral on the Debtor's premises; (d)
                        sell, lease or otherwise dispose of the Collateral, at
                        one or more locations, by public or private proceedings,
                        for cash or credit, without assumption of credit risk;
                        and/or (e) whether before or after default, collect and
                        receipt for, compound, compromise, and settle, and give
                        releases, discharges and acquittances with respect to,
                        any and all amounts owed by any person or entity with
                        respect to the Collateral. Unless the Collateral is
                        perishable or threatens to decline speedily in value or
                        is of a type customarily sold on a recognized market,
                        Secured Party will send Debtor reasonable notice of the
                        time and place of any public sale or of the time after
                        which any private sale or other disposition will be
                        made. Any requirement of reasonable notice to Debtor
                        shall be met if such notice is mailed, postage prepaid,
                        to Debtor at the address of Debtor designated at the
                        beginning of this Agreement, at least five (5) days
                        before the day of any public sale or at least five (5)
                        days before the time after which any private sale or
                        other disposition will be made.

                   iii.      EXPENSES.  Debtor shall be liable for and agrees to
                        pay the reasonable expenses incurred by Secured Party in
                        enforcing its rights and remedies, in retaking, holding,
                        testing, repairing, improving, selling, leasing or
                        disposing of the Collateral, or like expenses,
                        including, without limitation, attorneys' fees and legal
                        expenses incurred by Secured Party. These expenses,
                        together with interest thereon from date incurred until
                        paid by Debtor at the maximum contract rate allowed
                        under applicable laws, which Debtor agrees to pay, shall
                        constitute additional Obligations and shall be secured
                        by and entitled to the benefits of this Agreement.

                   iv.       PROCEEDS; SURPLUS; DEFICIENCIES. Proceeds received
                        by Secured Party from disposition of the Collateral
                        shall be applied toward Secured Party's expenses and
                        other Obligations in such order or manner as Secured
                        Party may elect. Debtor shall be entitled to any surplus
                        if one results after lawful application of the proceeds.
                        Debtor shall remain liable for any deficiency.

                   v.        REMEDIES CUMULATIVE. The rights and remedies of
                        Secured Party are cumulative and the exercise of any one
                        or more of the rights or remedies shall not be deemed an
                        election of rights or remedies or a waiver of any other
                        right or remedy. Secured Party may remedy any default
                        and may waive any default without waiving the default
                        remedied or without waiving any other prior or
                        subsequent default.

              l.        OTHER AGREEMENTS.

                   i.        SAVINGS CLAUSE.  Notwithstanding any provision to
                        the contrary herein, or in any of the documents
                        evidencing the Obligations or otherwise relating
                        thereto, no such provision shall require the payment or
                        permit the collection of interest in excess of the
                        maximum permitted by applicable usury laws. If any such
                        excessive interest is so provided for, then in such
                        event (i) the provisions of this paragraph shall govern
                        and control, (ii) neither the Debtor nor his heirs,
                        legal representatives, successors or assigns or any
                        other party liable for the payment thereof, shall be
                        obligated to pay the amount of such interest to the
                        extent that is in excess of the maximum amount permitted
                        by law, (iii) any such excess interest that may have
                        been collected shall be, at the option of the holder of
                        the instrument evidencing the Obligations, either
                        applied as a credit against the then unpaid principal
                        amount thereof or refunded to the maker thereof, and
                        (iv) the effective rate of interest shall be
                        automatically reduced to the maximum lawful rate under
                        applicable usury laws as now or hereafter construed by
                        the courts having jurisdiction.

                   ii.       JOINT AND SEVERAL RESPONSIBILITY. If this Security
                        Agreement is executed by more than one Debtor, the
                        obligations of all such Debtors shall be joint and
                        several.

                   iii.      WAIVERS. Debtor and any maker, endorser, guarantor,
                        surety or other party liable in any capacity respecting
                        the Obligations hereby waive demand, notice of intention

                   iv.       SEVERABILITY. Any provision hereof found to be
                        invalid by courts having jurisdiction shall be invalid
                        only with respect to such provision (and then only to
                        the extent necessary to avoid such invalidity). The
                        offending provision shall be modified to the maximum
                        extent possible to confer upon Secured Party the
                        benefits intended thereby. Such provision as modified
                        and the remaining

                                it. Secured Party is hereby authorized to act as
                                attorney for Debtor in obtaining, adjusting,
                                settling and canceling such insurance and
                                endorsing any drafts or instruments. Secured
                                Party shall be authorized to apply the proceeds
                                from any insurance to the Obligations secured
                                hereby whether or not such Obligations are then
                                due and payable. Debtor specifically authorizes
                                Secured Party to disclose information from the
                                policies of insurance to prospective insurers
                                regarding the Collateral.

                        xiv.        ADDITIONAL COLLATERAL. If Secured Party 
                                should at any time be of the opinion that the
                                Collateral is impaired, not sufficient or has
                                declined or may decline in value, or should
                                Secured Party deem payment of the Obligations to
                                be insecure, then Secured Party may call for
                                additional security satisfactory to Secured
                                Party, and Debtor promises to furnish such
                                additional security forthwith. The call for
                                additional security may be oral, by telegram, or
                                United States mail addressed to Debtor, and
                                shall not affect any other subsequent right of
                                Secured Party to exercise the same.

                f.              ADDITIONAL PROVISIONS REGARDING ACCOUNTS. The 
                        following provisions shall apply to all accounts 
                        included within the Collateral:

                        i.          DEFINITIONS. The term "account", as used in
                                this Agreement, shall have the same meaning as
                                set forth in the Uniform Commercial Code of
                                Texas in effect as of the date of execution
                                hereof, and as set forth in any amendment to the
                                Uniform Commercial Code of Texas to become
                                effective after the date of execution hereof,
                                and also shall include all present and future
                                notes, instruments, documents, general
                                intangibles, drafts, acceptances and chattel
                                paper of Debtor, and the proceeds thereof.

                        ii.         ADDITIONAL WARRANTIES. As of the time any
                                account becomes subject to the security interest
                                (or pledge of assignment as applicable) granted
                                hereby, Debtor shall be deemed further to have


                                       7

                                warranted as to each and all of such accounts as
                                follows: (a) each account and all papers and
                                documents relating thereto are genuine and in
                                all respects what they purport to be; (b) each
                                account is valid and subsisting and arises out
                                of a bona fide sale of goods sold and delivered
                                to, or out of and for services theretofore
                                actually rendered by the Debtor to, the account
                                debtor named in the account; (c) the amount of
                                the account represented as owing is the correct
                                amount actually and unconditionally owing except
                                for normal cash discounts and is not subject to
                                any set-offs, credits, defenses or counter-
                                charges; and (d) Debtor is the owner thereof
                                free and clear of any charges, liens, security
                                interests, adverse claims and encumbrances of
                                any and every nature whatsoever.

                        iii.        COLLECTION OF ACCOUNTS. Secured Party shall
                                have the right in its own name or in the name of
                                the Debtor, whether before or after default, to
                                require Debtor forthwith to transmit all
                                proceeds of collection of accounts to Secured
                                Party, to notify any and all account debtors to
                                make payments of the accounts directly to
                                Secured Party, to demand, collect, receive,
                                receipt for, sue for, compound and give
                                acquittal for, any and all amounts due or to
                                become due on the accounts and to endorse the
                                name of the Debtor on all commercial paper given
                                in payment or part payment thereof, and in
                                Secured Party's discretion to file any claim or
                                take any other action or proceeding that Secured
                                Party may deem necessary or appropriate to
                                protect and preserve and realize upon the
                                accounts and related Collateral. Unless and
                                until Secured Party elects to collect accounts,
                                and the privilege of Debtor to collect accounts
                                is revoked by Secured Party in writing, Debtor
                                shall continue to collect accounts, account for
                                same to Secured Party, and shall not commingle
                                the proceeds of collection of accounts with any
                                funds of the Debtor. In order to assure
                                collection of accounts in which Secured Party
                                has a security interest (or pledge or assignment
                                of as applicable) hereunder, Secured Party may
                                notify the post office authorities to change the
                                address for delivery of mail addressed to Debtor
                                to such address as Secured Party may designate,
                                and to open and dispose of such mail and receive
                                the collections of accounts included herewith.
                                Secured Party shall have no duty or obligation
                                whatsoever to collect any account, or to take
                                any other action to preserve or protect the
                                Collateral; however, should Secured Party elect
                                to collect any account or take possession of any
                                Collateral, Debtor releases Secured Party from
                                any claim or claims for loss or damage arising
                                from any act or omission in connection
                                therewith.

                        iv.         IDENTIFICATION AND ASSIGNMENT OF ACCOUNTS. 
                                Upon Secured Party's request, whether before or
                                after default, Debtor shall take

                                       8
<PAGE>   9

                                such action and execute and deliver such
                                documents as Secured Party may reasonably
                                request in order to identify, confirm, mark,
                                segregate and assign accounts and to evidence
                                Secured Party's interest in same. Without
                                limitation of the foregoing, Debtor, upon
                                request, agrees to assign accounts to Secured
                                Party, identify and mark accounts as being
                                subject to the security interest (or pledge or
                                assignment as applicable) granted hereby, mark
                                Debtor's books and records to reflect such
                                assignments, and forthwith to transmit to
                                Secured Party in the form as received by Debtor
                                any and all proceeds of collection of such
                                accounts.

                        v.          ACCOUNT REPORTS. Upon Secured Party's 
                                request, Debtor will deliver to Secured Party,
                                prior to the tenth (10th) day of each month, or
                                on such other frequency as Secured Party may
                                request, a written report in form and content
                                satisfactory to Secured Party, showing a listing
                                and aging of accounts and such other information
                                as Secured Party may request from time to time.
                                Debtor shall immediately notify Secured Party of
                                the assertion by any account debtor of any
                                set-off, defense or claim regarding an account
                                or any other matter adversely affecting an
                                account.

                        vi.         SEGREGATION OF RETURNED GOODS. Returned or
                                repossessed goods arising from or relating to
                                any accounts included within the Collateral
                                shall if requested by Secured Party be held
                                separate and apart from any other property.
                                Debtor shall as often as requested by Secured
                                Party, but not less often than weekly even
                                though no special request has been made, report
                                to Secured Party the appropriate identifying
                                information with respect to any such returned or
                                repossessed goods relating to accounts included
                                in assignments or identifications made pursuant
                                hereto.

                g.              ADDITIONAL PROVISIONS REGARDING INVENTORY. The 
                        following provisions shall apply to all inventory 
                        included within the Collateral:

                        i.          INVENTORY REPORTS. Upon request by Secured
                                Party, Debtor will deliver to Secured Party,
                                prior to the tenth (10th) day of each month, or
                                on such other frequency as Secured Party may
                                request, a written report in form and content
                                satisfactory to Secured Party, with respect to
                                the preceding month or other applicable period,
                                showing Debtor's opening inventory, inventory
                                acquired, inventory sold, inventory returned,
                                inventory used in Debtor's business, closing
                                inventory, any other inventory not within the
                                preceding categories, and such other information
                                as Secured Party may request from time to time.
                                Debtor shall immediately notify Secured Party


                                       9
<PAGE>   10

                                of any matter adversely affecting the inventory,
                                including, without limitation, any event causing
                                loss or depreciation in the value of the
                                inventory and the amount of such possible loss
                                or depreciation.

                        ii.         LOCATION OF INVENTORY. Debtor will promptly
                                notify Secured Party in writing of any addition
                                to, change in or discontinuance of its place(s)
                                of business as shown in this agreement, the
                                places at which inventory is located as shown
                                herein, the location of its chief executive
                                office and the location of the office where it
                                keeps its records as set forth herein. All
                                Collateral will be located at the place(s) of
                                business shown at the beginning of this
                                agreement as modified by any written notice(s)
                                given pursuant hereto.

                        iii.        USE OF INVENTORY. Unless and until the 
                                privilege of Debtor to use inventory in the
                                ordinary course of Debtor's business is revoked
                                by Secured Party in the event of default or if
                                Secured Party deems itself insecure, Debtor may
                                use the inventory in any manner not inconsistent
                                with this Agreement, may sell that part of the
                                Collateral consisting of inventory provided that
                                all such sales are in the ordinary course of
                                business, and may use and consume any raw
                                materials or supplies that are necessary in

                        iv.         VOTING RIGHTS. Upon default, or if Secured 
                                Party deems itself insecure, Secured Party shall
                                have the right, at its discretion, to transfer
                                to or register in the name of Secured Party or

                                rights as to any or all of the Collateral. For
                                such purposes, Debtor hereby names, constitutes
                                and appoints the President or any Vice President
                                of Secured Party as Debtor's proxy in the
                                Debtor's name, place and stead to vote any and
                                all of the securities, as such proxy may elect,
                                for and in the name, place and stead of Debtor,

                                with an interest. The rights, powers and
                                authority of said proxy shall remain in full
                                force and effect, and shall not be rescinded,
                                revoked, terminated,

                                amended or otherwise modified, until all
                                Obligations have been fully satisfied.

                        v.          NO DUTY. Secured Party shall never be liable
                                for its failure to give notice to Debtor of
                                default in the payment of or upon the
                                Collateral. Secured Party shall have no duty to
                                fix or preserve rights against prior parties to
                                the Collateral and shall never be liable for its
                                failure to use diligence to collect any amount
                                payable in respect to the Collateral, but shall
                                be liable only to account to Debtor for what it
                                may actually collect or receive thereon. Without
                                limiting the foregoing, it is specifically
                                understood and agreed that Secured Party shall
                                have no responsibility for ascertaining any
                                maturities, calls, conversions, exchanges,
                                offers, tenders, or similar matters relating to
                                any of the Collateral or for informing Debtor
                                with respect to any of such matters
                                (irrespective of whether Secured Party actually
                                has, or may be deemed to have, knowledge
                                thereof). The foregoing provisions of this
                                paragraph shall be fully applicable to all
                                securities or similar property held in pledge
                                hereunder, irrespective of whether Secured Party
                                may have exercised any right to have such
                                securities or similar property registered in its
                                name or in the name of a nominee.

                        vi.         FURTHER ASSURANCES. Debtor agrees to execute
                                such stock powers, endorse such instruments, or
                                execute such additional pledge agreements or
                                other documents as may be required by the
                                Secured Party in order effectively to grant to
                                Secured Party the security interest in (and
                                pledge and assignment of) the Collateral and to
                                enforce and exercise Secured Party's rights
                                regarding same.

                        vii.        SECURITIES LAWS. Debtor hereby agrees to
                                cooperate fully with Secured Party in order to
                                permit Secured Party to sell, at foreclosure or
                                other private sale, the Collateral pledged
                                hereunder. Specifically, Debtor agrees to fully
                                comply with the securities laws of the United
                                States and of the State of Texas and to take
                                such action as may be necessary to permit
                                Secured Party to sell or otherwise transfer the
                                securities pledged hereunder in compliance with
                                such laws. Without limiting the foregoing,
                                Debtor, at its own expense, upon request by
                                Secured Party, agrees to effect and obtain such
                                registrations, filings, statements, rulings,
                                consents, and other matters as Secured Party may
                                request.

                        viii.       POWER OF ATTORNEY. Debtor hereby makes,
                                constitutes and appoints Secured Party or its
                                nominee, its true and lawful attorney in fact
                                and in its name, place, and stead, and on its
                                behalf, and for its use and benefit to complete,
                                execute and file with the United

                                States Securities and Exchange Commission one or
                                more notices of proposed sale of securities
                                pursuant to Rule 144 under the Securities Act of
                                1933 and/or any similar filings or notices with
                                any applicable state agencies, and said attorney
                                in fact shall have full power and authority to
                                do, take and perform all and every act and thing
                                whatsoever requisite, proper or necessary to be
                                done, in the exercise of the rights and powers
                                herein granted, as fully to all intents and
                                purposes as Debtor might or could do if
                                personally present. This power shall be
                                irrevocable and deemed coupled with an interest.
                                The rights, powers and authority of said
                                attorney in fact herein granted shall commence
                                and be in full force and effect from the date of
                                this agreement, and such rights, powers and
                                authority shall remain in full force and effect,
                                and this power of attorney shall not be
                                rescinded, revoked, terminated, amended or
                                otherwise modified, until all Obligations have
                                been fully satisfied.

                        ix.         PRIVATE SALES. Because of the Securities Act
                                of 1933, as amended, or any other laws or
                                regulations, there may be legal restrictions or
                                limitations affecting Secured Party in any
                                attempts to dispose of certain portions of the
                                Collateral in the enforcement of its rights and
                                remedies hereunder. For these reasons Secured
                                Party is hereby authorized by Debtor, but not
                                obligated, in the event any default hereunder,
                                to sell all or any part of the Collateral at
                                private sale, subject to investment letter or in
                                any other manner which will not require the
                                Collateral, or any part thereof, to be
                                registered in accordance with the securities Act
                                of 1933, as amended, or the rules and
                                regulations promulgated thereunder, or any other
                                law or regulation. Secured Party is also hereby
                                authorized by Debtor, but not obligated, to take
                                such actions, give such notices, obtain such
                                rulings and consents, and do such other things
                                as Secured Party may deem appropriate in the
                                event of a sale or disposition of any of the
                                Collateral. Debtor clearly understands that
                                Secured Party may in its discretion approach a
                                restricted number of potential purchasers and
                                that a sale under such circumstances may yield a
                                lower price for the Collateral or any part or
                                parts thereof than would otherwise be obtainable
                                if same were registered and sold in the open
                                market, and Debtor agrees that such private
                                sales shall constitute a commercially reasonable
                                method of disposing of the Collateral.

                i.          ADDITIONAL PROVISIONS REGARDING CERTIFICATES OF 
                        DEPOSIT AND SIMILAR COLLATERAL. The following provisions
                        shall apply to certificates of deposit and similar
                        property included within the Collateral:

                        i.          COLLECTION OF DEPOSITS. Debtor agrees that
                                Secured Party may, at any time (whether before
                                or after default) and in its sole discretion,
                                surrender for payment and obtain payment of any
                                portion of the Collateral, whether such have
                                matured or the exercise of Secured Party's
                                rights results in loss of interest or principal
                                or other penalty on such deposits, and, in
                                connection therewith, cause payment to be made
                                directly to Secured Party.

                        ii.         NOTICE TO THIRD PARTY ISSUER. With regard to
                                any certificates of deposit or similar
                                Collateral for which Secured Party is not the
                                issuer, Debtor agrees to notify the issuer or
                                obligor of the interests hereby granted to
                                Secured Party and to obtain from such issuer or
                                obligor acknowledgement of the interests in
                                favor of Secured Party and the issuer's or
                                obligor's agreement to waive in favor of Secured
                                Party any and all rights of set-off or similar
                                rights or remedies to which such issuer or
                                obligor may be entitled, and, in connection
                                therewith, to execute and cause the issuer or
                                obligor to execute, any and all acknowledgments,
                                waivers and other agreements in such form and
                                upon such terms as Secured Party may request.

                        iii.        PROCEEDS. Any and all replacement or renewal
                                certificates, instruments, or other benefits or
                                proceeds related to the Collateral that are
                                received by Debtor shall be held by Debtor in
                                trust for Secured Party and immediately
                                delivered to Secured Party to be held as part of
                                the Collateral.

                        iv.         NO DUTY. Secured Party shall never be liable
                                for its failure to give notice to Debtor of
                                default in the payment of or upon the
                                Collateral. Secured Party shall have no duty to
                                fix or preserve rights against prior parties to
                                the Collateral and shall never be liable for its
                                failure to use diligence to collect any amount
                                payable in respect to the Collateral, but shall
                                be liable only to account to Debtor for what it
                                may actually collect or receive thereon. Without
                                limiting the foregoing, it is specifically
                                understood and agreed that Secured Party shall
                                have no responsibility for ascertaining any
                                maturities or similar matters relating to any of
                                the Collateral or for informing Debtor with
                                respect to any of such matters (irrespective of
                                whether Secured Party actually has, or may be
                                deemed to have, knowledge thereof).

                     j.         EVENTS OF DEFAULT. Debtor shall be in default 
                        hereunder upon the happening of any of the following
                        events or conditions: (i) non-payment when due (whether
                        by acceleration of maturity or otherwise) of any payment
                        of principal, interest or other amount due on any
                        Obligation;


                                       14

                                (ii) the occurrence of any event which under the
                                terms of any evidence of indebtedness,
                                indenture, loan agreement, security agreement or
                                similar instrument permits the acceleration of
                                maturity of any obligation of Debtor or BearCom,
                                Inc. (whether to Secured Party or to others);
                                (iii) any representation or warranty made by
                                Debtor to Secured Party in connection with this
                                Agreement, the Collateral or the Obligations, or
                                in any statements or certificates, proves
                                incorrect in any material respect as of the date
                                of the making or the issuance thereof; (iv)
                                default occurs in the observance or performance
                                of, or if Debtor fails to furnish adequate
                                evidence of performance of, any provision of
                                this Agreement or of any note, assignment,
                                transfer, other agreement, document or
                                instrument delivered by Debtor to Secured Party
                                in connection with this Agreement, the
                                Collateral or the Obligations; (v) death,
                                dissolution, liquidation, termination of
                                existence, insolvency, business failure or
                                winding-up of Debtor or any maker, endorser,
                                guarantor, surety or other party liable in any
                                capacity for any of the Obligations; (vi) the
                                commission of an act of bankruptcy by, or the
                                application for appointment of a receiver or any
                                other legal custodian for any part of the
                                property of, assignment for the benefit of
                                creditors by, or the commencement of any
                                proceedings under any bankruptcy, arrangement,
                                reorganization, insolvency or similar laws for
                                the relief of debtors by or against, the Debtor
                                or any maker, endorser, guarantor, surety or
                                other party primarily or secondarily liable for
                                any of the Obligations; (vii) the Collateral
                                becomes, in the judgment of Secured Party,
                                impaired, unsatisfactory or insufficient in
                                character or value; or (viii) the filing of any
                                levy, attachment, execution, garnishment or
                                other process against the Debtor or any of the
                                Collateral or any maker, endorser, guarantor,
                                surety, or other party liable in any capacity
                                for any of the Obligations.

                k           REMEDIES. Upon the occurrence of an event of 
                        default, or if Secured Party deems payment of the
                        Obligations to be insecure, Secured Party, at its
                        option, shall be entitled to exercise any one or more of
                        the following remedies (all of which are cumulative):

                        i           DECLARE OBLIGATIONS DUE. Secured
                                Party, at its option, may declare the
                                Obligations or any part thereof immediately due
                                and payable, without demand, notice of intention
                                to accelerate, notice of acceleration, notice of
                                non-payment, presentment, protest, notice of
                                dishonor, or any other notice whatsoever, all of
                                which are hereby waived by Debtor and any maker,
                                endorser, guarantor, surety or other party
                                liable in any capacity for any of the
                                Obligations.

                        ii          REMEDIES. Secured Party shall have all of 
                                the rights and remedies provided for in this
                                Agreement and in any other agreements executed
                                by Debtor, the rights and remedies of the
                                Uniform Commercial Code of Texas, and any and
                                all of the rights


                                       15
<PAGE>   16

                                and remedies at law and in equity, all of which
                                shall be. deemed cumulative. Without limiting
                                the foregoing, Debtor agrees that Secured Party
                                shall have the right to: (a) require Debtor to
                                assemble the Collateral and make it available to
                                Secured Party at a place designated by Secured
                                Party that is reasonably convenient to both '
                                parties, which Debtor agrees to do; (b)
                                peaceably take possession of the Collateral and
                                remove same, with or without judicial process;
                                (c) without removal, render equipment included
                                within the Collateral unusable, and dispose of
                                the Collateral on the Debtor's premises; (d)
                                sell, lease or otherwise dispose of the
                                Collateral, at one or more locations, by public
                                or private proceedings, for cash or credit,
                                without assumption of credit risk; and/or (e)
                                whether before or after default, collect and
                                receipt for, compound, compromise, and settle,
                                and give releases, discharges and acquittances
                                with respect to, any and all amounts owed by any
                                person or entity with respect to the Collateral.
                                Unless the Collateral is perishable or threatens
                                to decline speedily in value or is of a type
                                customarily sold on a recognized market, Secured
                                Party will send Debtor reasonable notice of the
                                time and place of any public sale or of the time
                                after which any private sale or other
                                disposition will be made. Any requirement of
                                reasonable notice to Debtor shall be met if such
                                notice is mailed, postage prepaid, to Debtor at
                                the address of Debtor designated at the
                                beginning of this Agreement, at least five (5)
                                days before the day of any public sale or at
                                least five (5) days before the time after which
                                any private sale or other disposition will be
                                made.

                        iii         EXPENSES. Debtor shall be liable for and 
                                agrees to pay the reasonable expenses incurred
                                by Secured Party in enforcing its rights and
                                remedies, in retaking, holding, testing,

                                disposing of the Collateral, or like expenses,
                                including, without limitation, attorneys' fees
                                and legal expenses incurred by Secured Party.
                                These expenses, together with interest thereon
                                from date incurred until paid by Debtor at the
                                maximum contract rate allowed under applicable
                                laws, which Debtor agrees to pay, shall
                                constitute additional Obligations and shall be
                                secured by and entitled to the benefits of this
                                Agreement.

                        iv          PROCEEDS; SURPLUS; DEFICIENCIES. Proceeds
                                received by Secured Party from disposition of
                                the Collateral shall be applied toward Secured

                        v.          REMEDIES CUMULATIVE. The rights and remedies
                                of Secured Party are cumulative and the exercise
                                of any one or more of the rights or remedies
                                shall not be deemed an election of rights or
                                remedies or a waiver of any other right or
                                remedy. Secured Party may remedy any default and
                                may waive any default without waiving the
                                default remedied or without waiving any other
                                prior or subsequent default.

                    l.          OTHER AGREEMENTS.

                        i.          SAVINGS CLAUSE. Notwithstanding any 
                                provision to the contrary herein, or in any of
                                the documents evidencing the Obligations or
                                otherwise relating thereto, no such provision
                                shall require the payment or permit the
                                collection of interest in excess of the maximum
                                permitted by applicable usury laws. If any such
                                excessive interest is so provided for, then in
                                such event (i) the provisions of this paragraph
                                shall govern and control, (ii) neither the
                                Debtor nor his heirs, legal representatives,
                                successors or assigns or any other party liable
                                for the payment thereof, shall be obligated to
                                pay the amount of such interest to the extent
                                that is in excess of the maximum amount
                                permitted by law, (iii) any such excess interest
                                that may have been collected shall be, at the
                                option of the holder of the instrument
                                evidencing the Obligations, either applied as a
                                credit against the then unpaid principal amount
                                thereof or refunded to the maker thereof, and
                                (iv) the effective rate of interest shall be
                                automatically reduced to the maximum lawful rate
                                under applicable usury laws as now or hereafter
                                construed by the courts having jurisdiction.

                        ii.         JOINT AND SEVERAL RESPONSIBILITY. If this
                                Security Agreement is executed by more than one
                                Debtor, the obligations of all such Debtors
                                shall be joint and several.

                        iii.        WAIVERS. Debtor and any maker, endorser,
                                guarantor, surety or other party liable in any
                                capacity respecting the Obligations hereby waive
                                demand, notice of intention to accelerate,
                                notice of acceleration, notice of non-payment,
                                presentment, protest, notice of dishonor and any
                                other similar notice whatsoever.

                        iv.         SEVERABILITY. Any provision hereof found to
                                be invalid by courts having jurisdiction shall
                                be invalid only with respect to such provision
                                (and then only to the extent necessary to avoid
                                such invalidity). The offending provision shall
                                be modified to the maximum extent possible to
                                confer upon Secured Party the benefits intended
                                thereby. Such provision as modified and the
                                remaining

                                provisions hereof shall be construed and
                                enforced to the same effect as if such offending
                                provision (or portion thereof) had not been
                                contained herein, to the maximum extent
                                possible.

                        v.          USE OF COPIES. Any carbon, photographic or
                                other reproduction of any financing statement
                                signed by Debtor is sufficient as a financing
                                statement for all purposes, including without
                                limitation, filing in any state as may be
                                permitted by the provisions of the Uniform
                                Commercial Code of such state.

                        vi.         RELATIONSHIP TO OTHER AGREEMENTS. This 
                                Security Agreement and the security interests
                                (and pledges and assignments as applicable)
                                herein granted are in addition to (and not in
                                substitution, novation or discharge of) any and
                                all prior or contemporaneous security
                                agreements, security interests, pledges,
                                assignments, liens, rights, titles or other
                                interests in favor of Secured Party or assigned
                                to Secured Party by others in connection with
                                the Obligations. All rights and remedies of
                                Secured Party in all such agreements are
                                cumulative, but in the event of actual conflict
                                in terms and conditions, the terms and
                                conditions of the latest security agreement
                                shall govern and control.

                        vii.        NOTICES. Any notice or demand given by 
                                Secured Party to Debtor in connection with this

                                unless Debtor requests same in writing and,
                                provided further, that all Obligations have been
                                repaid and discharged in full and there are no

                      agreement to which Debtor is a party, or by which Debtor

                      Collateral, except as contemplated by this Agreement.

               v.          ADDRESSES. The address of Debtor designated at the 
                      beginning of this Agreement is Debtor's place of business
                      if Debtor has only one place of business; Debtor's chief
                      executive office if Debtor has more than one place of
                      business; or Debtor's residence if Debtor has no place of
                      business. Debtor agrees not to change such address without

                      purposes, or in any manner or for any purpose that would
                      expose the Collateral to unusual risk, or to penalty,
                      forfeiture or capture, or that would render inoperative
                      any insurance in connection with the Collateral.

               iv.         NO ENCUMBRANCES. Debtor agrees not to suffer or 
                      permit any charge, lien, security interest, adverse claim

                      the Collateral or any part thereof.

               v.          NO REMOVAL. Except as otherwise provided in this 
                      Agreement, Debtor shall not remove the Collateral from the

                      dispose of the Collateral, or any part thereof, or

               vii.        NOTICES AND REPORTS.  Debtor shall promptly notify 
                      Secured Party in writing of any change in the name,

                                        5
<PAGE>   6

                      leased premises, such landlord's waivers to be in such
                      form and upon such terms as are acceptable to Secured
                      Party.

              ix.          ADDITIONAL FILINGS. Debtor agrees to execute
                      and deliver such financing statement or statements, or
                      amendments thereof or supplements thereto, or other
                      documents as Secured Party may from time to time require
                      in order to comply with the Texas Uniform Commercial Code
                      (or other applicable state law of the jurisdiction where
                      any of the Collateral is located) and to preserve and
                      protect the Secured Party's rights to the Collateral.

              x.           PROTECTION OF COLLATERAL.  Secured Party, at its 
                      option, whether before or after default, but without any
                      obligation whatsoever to do so, may (a) discharge taxes,
                      claims, charges, liens, security interests, assessments or
                      other encumbrances of any and every nature whatsoever at
                      any time levied, placed upon or asserted against the
                      Collateral, (b) place and pay for insurance on the
                      Collateral, including insurance that only protects Secured
                      Party's interest, (c) pay for the repair, improvement,
                      testing, maintenance and preservation of the Collateral,
                      (d) pay any filing, recording, registration, licensing or
                      certification fees or other fees and charges related to
                      the Collateral, or (e) take any other action to preserve
                      and protect the Collateral and Secured Party's rights and
                      remedies under this Agreement as Secured Party may deem
                      necessary or appropriate. Debtor agrees that Secured Party
                      shall have no duty or obligation whatsoever to take any of
                      the foregoing action. Debtor agrees to promptly reimburse
                      Secured Party upon demand for any payment made or any
                      expense incurred by the Secured Party pursuant to this
                      authorization. These payments and expenditures, together
                      with interest thereon from date incurred until paid by
                      Debtor at the maximum contract rate allowed under
                      applicable laws, which Debtor agrees to pay, shall
                      constitute additional Obligations and shall be secured by
                      and entitled to the benefits of this Agreement.

              xi.          INSPECTION. Debtor shall at all reasonable times 
                      allow Secured Party by or through any of its officers,
                      agents, attorneys or accountants, to examine the
                      Collateral, wherever located, and to examine and make
                      extracts from Debtor's books and records.

              xii.         FURTHER ASSURANCES. Debtor shall do, make, procure, 
                      execute and deliver all such additional and further acts,
                      things, deeds, interests and assurances as Secured Party
                      may require from time to time to protect, assure and
                      enforce Secured Party's rights and remedies.

              xiii.        INSURANCE.  Debtor shall have and maintain insurance 
                      at all time with respect to all tangible Collateral
                      insuring against risks of fire (including so-called
                      extended coverage), theft and other risks as Secured Party
                      may require, containing such terms, in such form and
                      amounts and written by such companies as may be
                      satisfactory to Secured Party, all of such insurance to
                      contain loss payable clauses in favor of Secured Party as
                      its interest may appear. All policies of insurance shall
                      provide for ten (10) days' written minimum cancellation
                      notice to Secured Party and at the request of Secured
                      Party shall be delivered to and held by it. Secured Party
                      is hereby authorized to act as attorney for Debtor in
                      obtaining, adjusting, settling and canceling such
                      insurance and endorsing any drafts or instruments. Secured
                      Party shall be authorized to apply the proceeds from any
                      insurance to the Obligations secured hereby whether or not
                      such Obligations are then due and payable. Debtor
                      specifically authorizes Secured Party to disclose
                      information from the policies of insurance to prospective
                      insurers regarding the Collateral.

              xiv.         ADDITIONAL COLLATERAL.  If Secured Party should at 
                      any time be of the opinion that the Collateral is
                      impaired, not sufficient or has declined or may decline in
                      value, or should Secured Party deem payment of the
                      Obligations to be insecure, then Secured Party may call
                      for additional security satisfactory to Secured Party, and
                      Debtor promises to furnish such additional security
                      forthwith. The call for additional security may be oral,
                      by telegram, or United States mail addressed to Debtor,
                      and shall not affect any other subsequent right of Secured
                      Party to exercise the same.

         f.           ADDITIONAL PROVISIONS REGARDING ACCOUNTS.  The following 
              provisions shall apply to all accounts included within the 
              Collateral:

              i.           DEFINITIONS.  The term "account", as used in this
                      Agreement, shall have the same meaning as set forth in the
                      Uniform Commercial Code of Texas in effect as of the date
                      of execution hereof, and as set forth in any amendment to
                      the Uniform Commercial Code of Texas to become effective
                      after the date of execution hereof, and also shall include
                      all present and future notes, instruments, documents,
                      general intangibles, drafts, acceptances and chattel paper
                      of Debtor, and the proceeds thereof.

              ii.          ADDITIONAL WARRANTIES.  As of the time any account
                      becomes subject to the security interest (or pledge of 
                      assignment as

                      applicable) granted hereby, Debtor shall be deemed further
                      to have warranted as to each and all of such accounts as
                      follows: (a) each account and all papers and documents
                      relating thereto are genuine and in all respects what they
                      purport to be; (b) each account is valid and subsisting
                      and arises out of a bona fide sale of goods sold and
                      delivered to, or out of and for services theretofore
                      actually rendered by the Debtor to, the account debtor
                      named in the account; (c) the amount of the account
                      represented as owing is the correct amount actually and
                      unconditionally owing except for normal cash discounts and
                      is not subject to any set-offs, credits, defenses or
                      counter- charges; and (d) Debtor is the owner thereof free
                      and clear of any charges, liens, security interests,
                      adverse claims and encumbrances of any and every nature
                      whatsoever.

              iii.         COLLECTION OF ACCOUNTS.  Secured Party shall have 
                      the right in its own name or in the name of the Debtor,
                      whether before or after default, to require Debtor
                      forthwith to transmit all proceeds of collection of
                      accounts to Secured Party, to notify any and all account
                      debtors to make payments of the accounts directly to
                      Secured Party, to demand, collect, receive, receipt for,
                      sue for, compound and give acquittal for, any and all
                      amounts due or to become due on the accounts and to
                      endorse the name of the Debtor on all commercial paper
                      given in payment or part payment thereof, and in Secured
                      Party's discretion to file any claim or take any other
                      action or proceeding that Secured Party may deem necessary
                      or appropriate to protect and preserve and realize upon
                      the accounts and related Collateral. Unless and until
                      Secured Party elects to collect accounts, and the
                      privilege of Debtor to collect accounts is revoked by
                      Secured Party in writing, Debtor shall continue to collect
                      accounts, account for same to Secured Party, and shall not
                      commingle the proceeds of collection of accounts with any
                      funds of the Debtor. In order to assure collection of
                      accounts in which Secured Party has a security interest
                      (or pledge or assignment of as applicable) hereunder,
                      Secured Party may notify the post office authorities to
                      change the address for delivery of mail addressed to
                      Debtor to such address as Secured Party may designate, and
                      to open and dispose of such mail and receive the
                      collections of accounts included herewith. Secured Party
                      shall have no duty or obligation whatsoever to collect any
                      account, or to take any other action to preserve or
                      protect the Collateral; however, should Secured Party
                      elect to collect any account or take possession of any
                      Collateral, Debtor releases Secured Party from any claim
                      or claims for loss or damage arising from any act or
                      omission in connection therewith.

              iv.          IDENTIFICATION AND ASSIGNMENT OF ACCOUNTS.  Upon 
                      Secured Party's request, whether before or after default,
                      Debtor shall take such action and execute and deliver such
                      documents as Secured Party may reasonably request in order
                      to identify, confirm, mark, segregate and assign accounts
                      and to evidence Secured Party's interest in same. Without
                      limitation of the foregoing, Debtor, upon request, agrees
                      to assign accounts to Secured Party, identify and mark
                      accounts as being subject to the security interest (or
                      pledge or assignment as applicable) granted hereby, mark
                      Debtor's books and records to reflect such assignments,
                      and forthwith to transmit to Secured Party in the form as
                      received by Debtor any and all proceeds of collection of
                      such accounts.

              v.           ACCOUNT REPORTS.  Upon Secured Party's request, 
                      Debtor will deliver to Secured Party, prior to the tenth
                      (10th) day of each month, or on such other frequency as
                      Secured Party may request, a written report in form and
                      content satisfactory to Secured Party, showing a listing
                      and aging of accounts and such other information as
                      Secured Party may request from time to time. Debtor shall
                      immediately notify Secured Party of the assertion by any
                      account debtor of any set-off, defense or claim regarding
                      an account or any other matter adversely affecting an
                      account.

              vi.          SEGREGATION OF RETURNED GOODS.  Returned or 
                      repossessed goods arising from or relating to any accounts
                      included within the Collateral shall if requested by
                      Secured Party be held separate and apart from any other
                      property. Debtor shall as often as requested by Secured
                      Party, but not less often than weekly even though no
                      special request has been made, report to Secured Party the
                      appropriate identifying information with respect to any
                      such returned or repossessed goods relating to accounts
                      included in assignments or identifications made pursuant
                      hereto.

         g.           ADDITIONAL PROVISIONS REGARDING INVENTORY. The following 
              provisions shall apply to all inventory included within the 
              Collateral:

              i.           INVENTORY REPORTS.  Upon request by Secured Party, 
                      Debtor will deliver to Secured Party, prior to the tenth
                      (10th) day of each month, or on such other frequency as
                      Secured Party may request, a written report in form and
                      content satisfactory to Secured Party, with respect to the
                      preceding month or other applicable period, showing
                      Debtor's opening inventory, inventory acquired, inventory
                      sold, inventory returned, inventory used in Debtor's
                      business, closing inventory, any other inventory not
                      within the preceding



                                        9
<PAGE>   10




                      categories, and such other information as Secured Party
                      may request from time to time. Debtor shall immediately
                      notify Secured Party of any matter adversely affecting the
                      inventory, including, without limitation, any event
                      causing loss or depreciation in the value of the inventory
                      and the amount of such possible loss or depreciation.

              ii.          LOCATION OF INVENTORY.  Debtor will promptly notify
                      Secured Party in writing of any addition to, change in or
                      discontinuance of its place(s) of business as shown in
                      this agreement, the places at which inventory is located
                      as shown herein, the location of its chief executive
                      office and the location of the office where it keeps its
                      records as set forth herein. All Collateral will be
                      located at the place(s) of business shown at the beginning
                      of this agreement as modified by any written notice(s)
                      given pursuant hereto, and all Collateral shall be in
                      possession of Debtor unless Secured Party is otherwise
                      notified by Debtor in writing.

              iii.         USE OF INVENTORY.  Unless and until the privilege of 
                      Debtor to use inventory in the ordinary course of Debtor's
                      business is revoked by Secured Party in the event of
                      default or if Secured Party deems itself insecure, Debtor
                      may use the inventory in any manner not inconsistent with
                      this Agreement, may sell that part of the Collateral
                      consisting of inventory provided that all such sales are
                      in the ordinary course of business, and may use and
                      consume any raw materials or supplies that are necessary
                      in order to carry on Debtor's business. A sale in the
                      ordinary course of business does not include a transfer in
                      partial or total satisfaction of a debt.

              iv.          ACCOUNTS AS PROCEEDS. All accounts that are proceeds 
                      of the inventory included within the Collateral shall be
                      subject to all of the terms and provisions hereof
                      pertaining to accounts.

              v.           PROTECTION OF INVENTORY. Debtor shall take all 
                      action necessary to protect and preserve the inventory.

         h.           ADDITIONAL PROVISIONS REGARDING SECURITIES AND SIMILAR 
              COLLATERAL. The following provisions shall apply to all 
              securities and similar property included within the Collateral:

              i.           ADDITIONAL WARRANTIES. As to each and all 
                      securities and  similar property included within the
                      Collateral (including securities hereafter acquired that
                      are part of the Collateral), Debtor further represents
                      and warrants, as of the time of delivery of same to
                      Secured Party, as follows: (a) such securities are
                      genuine, validly issued and outstanding, fully paid and
                      nonassessable, and are not



                                       10
<PAGE>   11




                      issued in violation of the preemptive rights of any person
                      or of any agreement by which the issuer or obligor thereof
                      or Debtor is bound; (b) such securities are not subject to
                      any interest, option or right of any third person; (c)
                      such securities are in compliance with applicable law
                      concerning form, content and manner of preparation and
                      execution; and (d) Debtor acquired and holds the
                      securities in compliance with all applicable laws and
                      regulations.

              ii.          DIVIDENDS AND PROCEEDS.  Any and all payments, 
                      dividends, other distributions (including stock redemption
                      proceeds), or other securities in respect of or in
                      exchange for the Collateral, whether by way of dividends,
                      stock dividends, recapitalizations, mergers,
                      consolidations, stock splits, combinations or exchanges of
                      shares or otherwise, received by Debtor shall be held by
                      Debtor in trust for Secured Party and Debtor shall
                      immediately deliver same to Secured Party to be held as
                      part of the Collateral. Debtor may retain ordinary cash
                      dividends unless and until Secured Party requests that
                      same be paid and delivered to Secured Party (which Secured
                      Party may request either before or after default).

              iii.         COLLECTIONS.  Secured Party shall have the right at 
                      any time and from time to time (whether before or after
                      default) to notify and direct the issuer or obligor to
                      make all payments, dividends and distributions regarding
                      the Collateral directly to Secured Party. Secured Party
                      shall have the authority to demand of the issuer or
                      obligor, and to receive and receipt for, any and all
                      payments, dividends and other distributions payable in
                      respect thereof, regardless of the medium in which paid
                      and whether they are ordinary or extraordinary. Each
                      issuer and obligor making payment to Secured Party
                      hereunder shall be fully protected in relying on the
                      written statement of Secured Party that it then holds a
                      security interest which entitles it to receive such
                      payment, and the receipt by Secured Party for such payment
                      shall be full acquittance therefor to the one making such
                      payment.

              iv.          VOTING RIGHTS.  Upon default, or if Secured Party 
                      deems itself insecure, Secured Party shall have the right,
                      at its discretion, to transfer to or register in the name
                      of Secured Party or any nominee of Secured Party any of
                      the Collateral, and/or to exercise any or all voting
                      rights as to any or all of the Collateral. For such
                      purposes, Debtor hereby names, constitutes and appoints
                      the President or any Vice President of Secured Party as
                      Debtor's proxy in the Debtor's name, place and stead to
                      vote any and all of the securities, as such proxy may
                      elect, for and in the name, place and stead of Debtor, as
                      to all matters coming before shareholders, such



                                       11
<PAGE>   12

                      proxy to be irrevocable and deemed coupled with an
                      interest. The rights, powers and authority of said proxy
                      shall remain in full force and effect, and shall not be
                      rescinded, revoked, terminated, amended or otherwise
                      modified, until all Obligations have been fully satisfied.

              v.           NO DUTY.  Secured Party shall never be liable for 
                      its  failure to give notice to Debtor of default in the
                      payment of or upon the Collateral. Secured Party shall
                      have no duty to fix or preserve rights against prior
                      parties to the Collateral and shall never be liable for
                      its failure to use diligence to collect any amount
                      payable in respect to the Collateral, but shall be liable
                      only to account to Debtor for what it may actually
                      collect or receive thereon. Without limiting the
                      foregoing, it is specifically understood and agreed that
                      Secured Party shall have no responsibility for
                      ascertaining any maturities, calls, conversions,
                      exchanges, offers, tenders, or similar matters relating
                      to any of the Collateral or for informing Debtor with
                      respect to any of such matters (irrespective of whether
                      Secured Party actually has, or may be deemed to have,
                      knowledge thereof). The foregoing provisions of this
                      paragraph shall be fully applicable to all securities or
                      similar property held in pledge hereunder, irrespective
                      of whether Secured Party may have exercised any right to
                      have such securities or similar property registered in
                      its name or in the name of a nominee.

              vi.          FURTHER ASSURANCES. Debtor agrees to execute such 
                      stock powers, endorse such instruments, or execute such
                      additional pledge agreements or other documents as may be
                      required by the Secured Party in order effectively to
                      grant to Secured Party the security interest in (and
                      pledge and assignment of) the Collateral and to enforce
                      and exercise Secured Party's rights regarding same.

              vii.         SECURITIES LAWS.  Debtor hereby agrees to cooperate 
                      fully with Secured Party in order to permit Secured Party
                      to sell, at foreclosure or other private sale, the
                      Collateral pledged hereunder. Specifically, Debtor agrees
                      to fully comply with the securities laws of the United
                      States and of the State of Texas and to take such action
                      as may be necessary to permit Secured Party to sell or
                      otherwise transfer the securities pledged hereunder in
                      compliance with such laws. Without limiting the foregoing,
                      Debtor, at its own expense, upon request by Secured Party,
                      agrees to effect and obtain such registrations, filings,
                      statements, rulings, consents, and other matters as
                      Secured Party may request.

              viii.        POWER OF ATTORNEY.  Debtor hereby makes, constitutes 
                      and appoints Secured Party or its nominee, its true and
                      lawful attorney in fact and in its name, place, and stead,
                      and on its behalf, and for its use and benefit to
                      complete, execute and file with the United States
                      Securities and Exchange Commission one or more notices of
                      proposed sale of securities pursuant to Rule 144 under the
                      Securities Act of 1933 and/or any similar filings or
                      notices with any applicable state agencies, and said
                      attorney in fact shall have full power and authority to
                      do, take and perform all and every act and thing
                      whatsoever requisite, proper or necessary to be done, in
                      the exercise of the rights and powers herein granted, as
                      fully to all intents and purposes as Debtor might or could
                      do if personally present. This power shall be irrevocable
                      and deemed coupled with an interest. The rights, powers
                      and authority of said attorney in fact herein granted
                      shall commence and be in full force and effect from the
                      date of this agreement, and such rights, powers and
                      authority shall remain in full force and effect, and this
                      power of attorney shall not be rescinded, revoked,
                      terminated, amended or otherwise modified, until all
                      Obligations have been fully satisfied.

              ix.          PRIVATE SALES.  Because of the Securities Act of 
                      1933, as amended, or any other laws or regulations, there
                      may be legal restrictions or limitations affecting Secured
                      Party in any attempts to dispose of certain portions of
                      the Collateral in the enforcement of its rights and
                      remedies hereunder. For these reasons Secured Party is
                      hereby authorized by Debtor, but not obligated, in the
                      event any default hereunder, to sell all or any part of
                      the Collateral at private sale, subject to investment
                      letter or in any other manner which will not require the
                      Collateral, or any part thereof, to be registered in
                      accordance with the securities Act of 1933, as amended, or
                      the rules and regulations promulgated thereunder, or any
                      other law or regulation. Secured Party is also hereby
                      authorized by Debtor, but not obligated, to take such
                      actions, give such notices, obtain such rulings and
                      consents, and do such other things as Secured Party may
                      deem appropriate in the event of a sale or disposition of
                      any of the Collateral. Debtor clearly understands that
                      Secured Party may in its discretion approach a restricted
                      number of potential purchasers and that a sale under such
                      circumstances may yield a lower price for the Collateral
                      or any part or parts thereof than would otherwise be
                      obtainable if same were registered and sold in the open
                      market, and Debtor agrees that such private sales shall
                      constitute a commercially reasonable method of disposing
                      of the Collateral.

         i.           ADDITIONAL PROVISIONS REGARDING CERTIFICATES OF DEPOSIT 
              AND SIMILAR COLLATERAL.  The following



                                       13
<PAGE>   14

              provisions shall apply to certificates of deposit and
              similar property included within the Collateral:

              i.           COLLECTION OF DEPOSITS. Debtor agrees that Secured 
                      Party may, at any time (whether before or after default)
                      and in its sole discretion, surrender for payment and
                      obtain payment of any portion of the Collateral, whether
                      such have matured or the exercise of Secured Party's
                      rights results in loss of interest or principal or other
                      penalty on such deposits, and, in connection therewith,
                      cause payment to be made directly to Secured Party.

              ii.          NOTICE TO THIRD PARTY ISSUER.  With regard to any 
                      certificates of deposit or similar Collateral for which
                      Secured Party is not the issuer, Debtor agrees to notify
                      the issuer or obligor of the interests hereby granted to
                      Secured Party and to obtain from such issuer or obligor
                      acknowledgment of the interests in favor of Secured Party
                      and the issuer's or obligor's agreement to waive in favor
                      of Secured Party any and all rights of set-off or similar
                      rights or remedies to which such issuer or obligor may be
                      entitled, and, in connection therewith, to execute and
                      cause the issuer or obligor to execute, any and all
                      acknowledgments, waivers and other agreements in such form
                      and upon such terms as Secured Party may request.

              iii.         PROCEEDS. Any and all replacement or renewal 
                      certificates, instruments, or other benefits or proceeds
                      related to the Collateral that are received by Debtor
                      shall be held by Debtor in trust for Secured Party and
                      immediately delivered to Secured Party to be held as part
                      of the Collateral.

              iv.          NO DUTY.  Secured Party shall never be liable for 
                      its failure to give notice to Debtor of default in the
                      payment of or upon the Collateral. Secured Party shall
                      have no duty to fix or preserve rights against prior
                      parties to the Collateral and shall never be liable for
                      its failure to use diligence to collect any amount payable
                      in respect to the Collateral, but shall be liable only to
                      account to Debtor for what it may actually collect or
                      receive thereon. Without limiting the foregoing, it is
                      specifically understood and agreed that Secured Party
                      shall have no responsibility for ascertaining any
                      maturities or similar matters relating to any of the
                      Collateral or for informing Debtor with respect to any of
                      such matters (irrespective of whether Secured Party
                      actually has, or may be deemed to have, knowledge
                      thereof).

         j.                EVENTS OF DEFAULT.  Debtor shall be in default 
                      hereunder upon the happening of any of the following
                      events or conditions: (i) non- payment when due (whether
                      by acceleration of maturity or otherwise) of any payment
                      of principal, interest or other amount due on any
                      Obligation; (ii) the occurrence of any event which under
                      the terms of any evidence of indebtedness, indenture, loan
                      agreement, security agreement or similar instrument
                      permits the acceleration of maturity of any obligation of
                      Debtor or BearCom Operating, L.P. (whether to Secured
                      Party or to others); (iii) any representation or warranty
                      made by Debtor to Secured Party in connection with this
                      Agreement, the Collateral or the Obligations, or in any
                      statements or certificates, proves incorrect in any
                      material respect as of the date of the making or the
                      issuance thereof; (iv) default occurs in the observance or
                      performance of, or if Debtor fails to furnish adequate
                      evidence of performance of, any provision of this
                      Agreement or of any note, assignment, transfer, other
                      agreement, document or instrument delivered by Debtor to
                      Secured Party in connection with this Agreement, the
                      Collateral or the Obligations; (v) death, dissolution,
                      liquidation, termination of existence, insolvency,
                      business failure or winding-up of Debtor or any maker,
                      endorser, guarantor, surety or other party liable in any
                      capacity for any of the Obligations; (vi) the commission
                      of an act of bankruptcy by, or the application for
                      appointment of a receiver or any other legal custodian for
                      any part of the property of, assignment for the benefit of
                      creditors by, or the commencement of any proceedings under
                      any bankruptcy, arrangement, reorganization, insolvency or
                      similar laws for the relief of debtors by or against, the
                      Debtor or any maker, endorser, guarantor, surety or other
                      party primarily or secondarily liable for any of the
                      Obligations; (vii) the Collateral becomes, in the judgment
                      of Secured Party, impaired, unsatisfactory or insufficient
                      in character or value; or (viii) the filing of any levy,
                      attachment, execution, garnishment or other process

                      endorser, guarantor, surety, or other party liable in any
                      capacity for any of the Obligations.

         k.                REMEDIES. Upon the occurrence of an event of default,
                      or if Secured Party deems payment of the Obligations to be
                      insecure, Secured Party, at its option, shall be entitled
                      to exercise any one or more of the following remedies (all
                      of which are cumulative):

                      i.        DECLARE OBLIGATIONS DUE. Secured Party, at its 
                           option, may declare the Obligations or any part
                           thereof immediately due and payable, without demand,

                           acceleration, notice of non-payment, presentment,

                           party liable in any capacity for any of the
                           Obligations.



                                       15
<PAGE>   16

                      ii.       REMEDIES.  Secured Party shall have all of the 
                           rights and remedies provided for in this Agreement
                           and in any other agreements executed by Debtor, the
                           rights and remedies of the Uniform Commercial Code of
                           Texas, and any and all of the rights and remedies at
                           law and in equity, all of which shall be. deemed
                           cumulative. Without limiting the foregoing, Debtor
                           agrees that Secured Party shall have the right to:
                           (a) require Debtor to assemble the Collateral and
                           make it available to Secured Party at a place
                           designated by Secured Party that is reasonably
                           convenient to both parties, which Debtor agrees to
                           do; (b) peaceably take possession of the Collateral
                           and remove same, with or without judicial process;
                           (c) without removal, render equipment included within
                           the Collateral unusable, and dispose of the
                           Collateral on the Debtor's premises; (d) sell, lease
                           or otherwise dispose of the Collateral, at one or
                           more locations, by public or private proceedings, for
                           cash or credit, without assumption of credit risk;
                           and/or (e) whether before or after default, collect
                           and receipt for, compound, compromise, and settle,
                           and give releases, discharges and acquittances with
                           respect to, any and all amounts owed by any person or
                           entity with respect to the Collateral. Unless the
                           Collateral is perishable or threatens to decline
                           speedily in value or is of a type customarily sold on
                           a recognized market, Secured Party will send Debtor
                           reasonable notice of the time and place of any public
                           sale or of the time after which any private sale or
                           other disposition will be made. Any requirement of
                           reasonable notice to Debtor shall be met if such
                           notice is mailed, postage prepaid, to Debtor at the
                           address of Debtor designated at the beginning of this
                           Agreement, at least five (5) days before the day of
                           any public sale or at least five (5) days before the
                           time after which any private sale or other
                           disposition will be made.

                     iii.       EXPENSES.  Debtor shall be liable for and 
                           agrees  to pay the reasonable expenses incurred by
                           Secured Party in enforcing its rights and remedies,
                           in retaking, holding, testing, repairing, improving,
                           selling, leasing or disposing of the Collateral, or
                           like expenses, including, without limitation,
                           attorneys' fees and legal expenses incurred by
                           Secured Party. These expenses, together with
                           interest thereon from date incurred until paid by
                           Debtor at the maximum contract rate allowed under
                           applicable laws, which Debtor agrees to pay, shall
                           constitute additional Obligations and shall be
                           secured by and entitled to the benefits of this
                           Agreement.

                     iv.        PROCEEDS; SURPLUS; DEFICIENCIES. Proceeds
                           received by Secured Party from disposition of the
                           Collateral shall be applied toward Secured Party's
                           expenses and other Obligations in such

                           order or manner as Secured Party may elect. Debtor
                           shall be entitled to any surplus if one results after
                           lawful application of the proceeds. Debtor shall
                           remain liable for any deficiency.

                     v.         REMEDIES CUMULATIVE. The rights and remedies 
                           of Secured Party are cumulative and the exercise of
                           any one or more of the rights or remedies shall not
                           be deemed an election of rights or remedies or a
                           waiver of any other right or remedy. Secured Party
                           may remedy any default and may waive any default
                           without waiving the default remedied or without
                           waiving any other prior or subsequent default.

            l.             OTHER AGREEMENTS.

                     i.         SAVINGS CLAUSE.  Notwithstanding any provision 
                           to the contrary herein, or in any of the documents
                           evidencing the Obligations or otherwise relating
                           thereto, no such provision shall require the payment
                           or permit the collection of interest in excess of the
                           maximum permitted by applicable usury laws. If any
                           such excessive interest is so provided for, then in
                           such event (i) the provisions of this paragraph shall
                           govern and control, (ii) neither the Debtor nor his
                           heirs, legal representatives, successors or assigns
                           or any other party liable for the payment thereof,
                           shall be obligated to pay the amount of such interest
                           to the extent that is in excess of the maximum amount
                           permitted by law, (iii) any such excess interest that
                           may have been collected shall be, at the option of
                           the holder of the instrument evidencing the
                           Obligations, either applied as a credit against the
                           then unpaid principal amount thereof or refunded to
                           the maker thereof, and (iv) the effective rate of
                           interest shall be automatically reduced to the
                           maximum lawful rate under applicable usury laws as
                           now or hereafter construed by the courts having
                           jurisdiction.

                     ii.        JOINT AND SEVERAL RESPONSIBILITY. If this
                           Security Agreement is executed by more than one
                           Debtor, the obligations of all such Debtors shall be
                           joint and several.

                     iii.       WAIVERS. Debtor and any maker, endorser, 
                           guarantor, surety or other party liable in any
                           capacity respecting the Obligations hereby waive
                           demand, notice of intention to accelerate, notice of
                           acceleration, notice of non-payment, presentment,
                           protest, notice of dishonor and any other similar
                           notice whatsoever.

                     iv.        SEVERABILITY. Any provision hereof found to
                           be invalid by courts having jurisdiction shall be
                           invalid only with respect to such




                                       17
<PAGE>   18

                           provision (and then only to the extent necessary to
                           avoid such invalidity). The offending provision shall
                           be modified to the maximum extent possible to confer
                           upon Secured Party the benefits intended thereby.
                           Such provision as modified and the remaining
                           provisions hereof shall be construed and enforced to
                           the same effect as if such offending provision (or
                           portion thereof) had not been contained herein, to
                           the maximum extent possible.

                     v.         USE OF COPIES. Any carbon, photographic or other
                           reproduction of any financing statement signed by
                           Debtor is sufficient as a financing statement for all
                           purposes, including without limitation, filing in any
                           state as may be permitted by the provisions of the
                           Uniform Commercial Code of such state.

                     vi.        RELATIONSHIP TO OTHER AGREEMENTS.  This Security
                           Agreement and the security interests (and pledges and
                           assignments as applicable) herein granted are in
                           addition to (and not in substitution, novation or
                           discharge of) any and all prior or contemporaneous
                           security agreements, security interests, pledges,
                           assignments, liens, rights, titles or other interests
                           in favor of Secured Party or assigned to Secured
                           Party by others in connection with the Obligations.
                           All rights and remedies of Secured Party in all such
                           agreements are cumulative, but in the event of actual
                           conflict in terms and conditions, the terms and
                           conditions of the latest security agreement shall
                           govern and control.

                    vii.        NOTICES. Any notice or demand given by Secured 
                           Party to Debtor in connection with this Agreement,
                           the Collateral or the Obligations, shall be deemed
                           given and effective upon deposit in the United States
                           mail, postage prepaid, addressed to Debtor at the
                           address of Debtor designated at the beginning of this
                           Agreement. Actual notice to Debtor shall always be
                           effective no matter how given or received.

                    viii.       HEADINGS AND GENDER. Paragraph headings in
                           this Agreement are for convenience only and shall be
                           given no meaning or significance in interpreting this
                           Agreement. All words used herein shall be construed
                           to be of such gender or number as the circumstances
                           require.

                    ix.         AMENDMENTS. Neither this Agreement nor any
                           of its provisions may be changed, amended, modified,
                           waived or discharged orally, but only by an
                           instrument in writing signed by the party against
                           whom enforcement of the change, amendment,
                           modification, waiver or discharge is sought.

                    x.          CONTINUING AGREEMENT.  The security interest

                           granted and all of the terms and provisions in this
                           Agreement shall be deemed a continuing agreement and
                           shall continue in full force and effect until
                           terminated in writing. Any such revocation or
                           termination shall only be effective if explicitly
                           confirmed in a signed writing issued by Secured Party
                           to such effect and shall in no way impair or affect
                           any transactions entered into or rights created or
                           Obligations incurred or arising prior to such
                           revocation or termination as to which this Agreement
                           shall be fully operative until same are repaid and
                           discharged in full. Unless otherwise required by
                           applicable law, Secured Party shall be under no
                           obligation to issue a termination statement or
                           similar documents unless Debtor requests same in
                           writing and, provided further, that all Obligations
                           have been repaid and discharged in full and there are
                           no commitments to make advances, incur any
                           Obligations or otherwise give value.

                           Agreement shall be binding upon the heirs, personal

                           the rights, powers and remedies of Secured Party
                           hereunder shall inure to the benefit of the
                           successors and assigns of Secured Party.

                    xii.        GOVERNING LAW.  This Security Agreement shall 
                           be governed by the law of the State of Texas and
                           applicable federal law.

                    xiii.       AGREEMENT FOR BINDING ARBITRATION. DEBTOR

         Purchaser would pay the Company an additional amount equal to (i)

         Purchaser would pay the Company an additional amount equal to (i)

         Requested with SEC], the product of (A) [Confidential Treatment
         Requested with SEC] and (B) a fraction, the numerator of which is
         Adjusted Net Profits for such period and the denominator of which is
         [Confidential Treatment Requested with SEC].

                  (a) The Partners are the sole partners of the Company.

                  (b) The Assets include all of the assets reflected in the
         December 31, 1996 balance sheet of the Company previously delivered by
         the Company to Purchaser (other than inventory sold in the ordinary
         course of business since that date on a basis consistent with prior
         practices). The inventory amounts on the December 31, 1996 balance
         sheet reflect the cost of such inventory. The Company holds good and
         indefeasible title to the Assets, free and clear of all liens, claims
         and encumbrances. At the Closing Purchaser will acquire good and
         indefeasible title to the Assets, free and clear of all liens, claims
         and encumbrances.

                  (c) The Company has furnished to Purchaser the balance sheet
         and related statements of income, retained earnings, changes in
         stockholders' equity, and cash flows of the Company including the notes
         thereto at and for the period ending December 31, 1996 (collectively,
         the "Financial Statements"). The Financial Statements fairly present
         the financial condition and results of operations of the Company as of
         the dates and for the periods indicated and have been prepared in
         conformity with generally accepted accounting principles ("GAAP")
         applied on a consistent basis with prior practices. There were not any
         significant items of income or expense which were unusual or of a
         nonrecurring nature reflected in the Financial Statements.

                  (d) Except for those liabilities and obligations incurred in
         the ordinary course of business consistent with prior practices since
         the date of the Financial Statements, the Financial Statements reflect
         all liabilities and obligations of the Company, accrued, contingent or
         otherwise (known or unknown and asserted or unasserted), arising out of
         transactions effected or events occurring on or prior to the Closing
         Date. All allowances and reserves shown in the Financial Statements are
         appropriate, reasonable and sufficient to provide for expenses and
         losses thereby contemplated. The Company is not liable upon or with
         respect to, or obligated in any other way to provide funds in respect
         of or to guarantee or assume in any manner, any debt, obligation or
         dividend of any person, corporation, association, partnership, joint
         venture, trust or other entity. The Company and each of the Partners
         knows of no basis for the assertion of any other claims or liabilities
         of any nature or in any amount.

                  (e) This Agreement has been duly authorized, executed and
         delivered by the Company and the Partners and is a valid and binding
         agreement of the Company and the Partners, enforceable against each
         such party in accordance with its terms.

                  (f) Neither the execution and delivery of this Agreement nor
         the consummation of the transactions contemplated herein violates any
         law, agreement, mortgage or other instrument or provision of law to
         which or under which the Company or the Partners are a party or bound.

                  (g) Except for the consents set forth on Schedule 4(g) hereto,
         no consents or approvals are required for execution of this Agreement
         by the Company and the Partners or their consummation of the
         transactions contemplated herein.

                  (h) There is no judicial, administrative or arbitral action,
         suit, proceeding (public or private), claim or demand pending or, to
         the knowledge of the Company and the Partners, threatened against the
         Company or its business.

                  (i) The Company and its business are, and have been, in
         compliance with all applicable laws, rules, regulations, ordinances,
         licenses, permits and orders. The Company has maintained all employee
         benefit plans and arrangements in accordance with all applicable laws,
         rules and regulations including the Internal Revenue Code of 1986, as
         amended, and the Employee Retirement Income Security Act of 1974, as
         amended, and have timely filed with all applicable regulatory
         authorities all applicable reports and returns required to be filed by
         them with respect to its employee benefit plans and arrangements.

                  (j) The Company has no liabilities for federal, state or local
         taxes, including but not limited to income, estimated, sales, use, ad
         valorem, personal property, franchise, payroll, employment, social
         security, unemployment, and disability taxes.

                  (k) The Company has not suffered any material adverse change
         in its business, operations, financial condition or prospects from that
         heretofore represented to Purchaser or its affiliates, officers or
         representatives.

                  (l) The distribution agreement between the Company and
         Motorola, Inc. ("Motorola Contract") and all other contracts being
         assigned by the Company to Purchaser pursuant hereto are in full force
         and effect. Neither party to any such contract is in default under any
         of such contracts, and no event has occurred that would, with the
         passage of time, cause a default under any of such contracts. The
         Company has paid the other party to each such contract all amounts it
         owes them whether or not such amounts are yet due. The Company has
         provided Purchaser with true, correct, and current copies of all such
         contracts. There are no other contracts that are material to the
         Company's business.

                  (m) Set forth in Schedule 4(m) hereto is a complete and
         accurate list of all employees of the Company, together with their
         dates of hire, positions and their annual salaries and other
         compensation. The Company has not granted or become obligated to grant
         any increases in the wages or salary of, or paid or become obligated to
         pay any bonus or made or become obligated to make any similar payment
         to or grant any benefit to or on behalf of, any officer, employee or
         agent. The Company has no direct or indirect, express or implied,
         obligation to pay severance or termination pay to any officer or
         employee of the Company or to pay any amounts to any consultant, agent
         or similar person or entity. The Company and the Partners have no
         knowledge of any facts which would indicate that any employee of the
         Company will not accept employment with Purchaser on a basis no less
         favorable than that upon which such employee is currently employed by
         the Company.

                  (n) All of the fixed assets (including but not limited to all
         equipment), owned or leased by the Company are in good condition and
         repair, fit for their intended use in the ordinary course


                                       -4-

<PAGE>   5



         of business, and conform in all respects with all applicable
         ordinances, regulations and other laws and there are no known latent
         defects therein. All regular maintenance or service requirements, and
         product recalls, have been followed, installed, or otherwise
         implemented on and with respect to the Assets. All inventory of the
         Company is in good, current, standard, and merchantable condition and
         is not obsolete or defective. The inventory of the Company is properly
         recorded on the Financial Statements at the lower of cost (last
         in-first out) or market in accordance with GAAP.

                  (o) The books of account of the Company have been kept
         accurately in the ordinary course of its business, the transactions
         entered therein represent bona fide transactions and the revenues,
         expenses, assets and liabilities of the Company have been properly
         recorded in such books. The records are in good order, are complete,
         and have been maintained in accordance with sound business practices.

                  (p) Set forth in Schedule 4(p) hereto is a complete and
         accurate list and description of all accounts receivable of the
         Company's business from sales made as of December 31, 1996, and the
         payments and rights to receive payments related thereto. All of the
         accounts receivable are free and clear of any security interests,
         liens, encumbrances, or other charges; none of such accounts receivable
         are subject to any offsets or claims of offsets; and none of the
         obligors of the accounts receivable have given notice that they will or
         may refuse to pay the full amount thereof or any portion thereof. All
         accounts receivable, net of an allowance for bad debts in the amount of
         $_________, will be collected in the usual and ordinary course of
         business within 90 days after the Closing assuming Purchaser undertakes
         reasonable efforts to collect these accounts.

                  (q) No distribution, payment, or dividend of any kind has been
         declared or paid by the Company to its Partners at any time since
         November 30, 1996 and, except for amounts agreed to in writing by
         Purchaser, none will be declared or paid after the date hereof until
         the consummation of the transactions contemplated hereby. The parties
         hereto agree that such additional distributions would only be agreed to
         by Purchaser to the extent required to cover the Partners' 1996 income
         tax liability relating to the profits of the Company and only if, and
         to the extent, the net worth of the Company (determined in accordance
         with generally accepted accounting principles) as of the Closing and
         after such distributions would equal or exceed $116,806.

                  (r) No Partner, director, or officer of the Company, nor any
         person who is a spouse or descendant of such Partner, director or
         officer, has any direct or indirect relationship with any customer or
         supplier of, or other contracting party with, the Company.

                  (s) Neither the Company nor any Partner knows or has any
         reason to believe, or has received notice or information, that any
         supplier of the Company will cease or refuse to do business with
         Purchaser after the consummation of the transactions contemplated
         hereby in the same manner, and same amount, as previously conducted
         with the Company. Neither the Company nor any Partner has received any
         notice of any disruption (including delayed deliveries or allocations
         by suppliers or service providers) in the availability of the products
         used by the Company, nor is the Company or any Partner aware of any
         facts which could lead the Company to believe that the Company or
         Purchaser will be subject to any such material disruption. Neither the
         Company nor any Partner is aware of any condition (financial or
         otherwise) affecting any supplier that will, or could be reasonably
         expected to, now or in the future, reduce each such


                                       -5-

<PAGE>   6



         supplier's ability to do business with Purchaser in substantially the
         same manner and amount that each such supplier has done business with
         the Company during the period preceding this Agreement. Set forth in
         Schedule 4(s) is a complete and accurate list and description of all
         volume discounts and other discounts provided by any supplier of the
         Company.

                  (t) All information furnished to Purchaser by the Company or
         the Partners, whether or not herein or in any Exhibit or Schedule
         hereto, is true, correct, and complete. Such information states all
         material facts required to be stated therein or necessary to make the
         statements therein, in light of the circumstances under which such
         statements are made, true, correct and complete in all material
         respects. The Company and the Partners have made due inquiry and
         investigation concerning the matters to which representations and
         warranties of the Company and the Partners under this Agreement pertain
         and the Company and the Partners, and each of them, are unaware of any
         facts, events or circumstances which have not been disclosed to
         Purchaser which are material to the Assets, the business of the
         Company, or the Company.

The representations, warranties and covenants of the Company and the Partners
set forth in this Agreement shall survive execution and delivery of this
Agreement and the Closing.

         5. Closing. The closing of the transactions contemplated hereby (the
"Closing") will take place concurrently with the execution of this Agreement at
the offices of the Company (or such other place as may be mutually agreed upon
by the parties hereto). The day on which the Closing occurs is herein referred
to as the "Closing Date."

         6. Deliveries at Closing.    At the Closing,

                  (a) the Company shall execute and deliver to Purchaser a bill
         of sale in the form reasonably requested by Purchaser and shall deliver
         a list of the fixed assets, inventory and rental two-way radios owned
         by the Company as of the Closing;

                  (b) the Company shall endorse and deliver to Purchaser
         certificates of title relating to all vehicles owned by the Company;

                  (c) Purchaser shall deliver [Confidential Treatment Requested
         with SEC] to the Company by Purchaser check or wire transfer;

                  (d) counsel to the Company shall deliver to Purchaser a legal
         opinion dated the Closing Date in form reasonably acceptable to
         Purchaser opining to the matters set forth in Exhibit C hereto;

                  (e) the Company's accounting firm shall deliver a letter dated
         the Closing Date and addressed to Purchaser stating that to its
         knowledge that there are no pending audits or investigations involving
         the Company and that it has no reason to believe that the Financial
         Statements do not fairly present the financial condition of the Company
         at and for the periods set forth therein;



                                       -6-

<PAGE>   7



                  (f) the Company shall deliver evidence of receipt of all
         required approvals, consents, licenses and permits to the transactions
         contemplated herein in a form acceptable to the Purchaser in its sole
         discretion; and

                  (g) the Company shall execute and deliver such other documents
         as are reasonably requested by Purchaser to effectuate the purposes and
         intent of this Agreement.

         7. Purchase Price Allocation. The parties hereto hereby agree that, for
all accounting and foreign, federal, state and local tax reporting purposes, the
Purchase Price shall be allocated in accordance with the relative fair market
values of the Assets and the non-competition covenant set forth in Section 9
hereof, as determined by Purchaser, as soon as practicable after the Closing
Date. Purchaser shall provide to the Company a schedule setting forth such
allocation as soon as practicable after the Closing Date, and shall thereafter
notify the Company of any changes thereto. Each of the parties hereto hereby
covenants and agrees that it will not take a position on any tax return, before
any governmental agency charged with the collection of any tax, or in any
judicial proceeding that is in any way inconsistent with the terms of this
Section 7.

         8. Confidentiality. The Company and the Partners agree to hold in
confidence the terms of this Agreement and, except as required by law, will not
make the same available or known to any third party other than their counsel,
accountants and other agents or representatives acting on their behalf, and then
only to the extent necessary, provided each such person is advised of the
confidential nature of the terms hereof and agrees to hold the same in
confidence.

         9. Noncompetition and Non-solicitation.

                  (a) For a period of two years after the end of the Second
         Earn-out Period, and except for services performed on behalf of
         Purchaser, the Company and the Partners agree that neither they nor any
         of their affiliates will directly or indirectly either as an
         individual, a partner or a joint venturer, or in any other capacity,
         (i) invest (other than investments in publicly-owned companies which
         constitute not more than 1% of the voting securities of any such
         company), or engage in, within the State of Massachusetts or Rhode
         Island (x) the business of selling, renting, or servicing any wireless
         communication products or (y) any other wireless business that is
         competitive with that of Purchaser or its affiliates (the items listed
         under clauses (x) and (y) hereto are collectively referred to herein as
         "Competitive Businesses"), or (ii) accept employment with or render
         services to Competitive Businesses that engages in such Competitive
         Business within the State of Massachusetts or Rhode Island as a
         director, officer, agent, employee, consultant, or any other capacity.
         For purposes of this Agreement, a "business that is competitive with
         that of Purchaser or its affiliates" specifically includes persons,
         firms, sole proprietorships, partnerships, companies, corporations or
         other entities that market products and/or perform services in direct
         or indirect competition with those marketed and/or performed by
         Purchaser or its affiliates within the State of Massachusetts or Rhode
         Island. The parties agree that, if such non-competition agreement is
         determined by a court of competent jurisdiction to be unenforceable,
         such agreement should be reformed by the court to the extent necessary
         to be enforceable and to give effect to the intent of this Section 9.

                  (b) After the Closing, neither the Company nor the Partners
         will, directly or indirectly, (i) solicit for employment by the Company
         or anyone else, any employee of Purchaser


                                       -7-

<PAGE>   8



         or its affiliates as a result of the transactions contemplated hereby
         or any person who was an employee of the Company or Purchaser or its
         affiliates within the four-month period immediately preceding such
         solicitation or employment, other than such person whose employment was
         terminated by Purchaser or its affiliates; or (ii) induce or attempt to
         induce, any such employee of Purchaser or its affiliates to terminate
         such employee's employment.

                  (c) The parties hereto acknowledge that the provisions of this
         Section 9 are supported by good and valuable consideration and
         Purchaser's agreement to consummate the transactions contemplated
         hereby are conditioned upon its receipt of the protection provided in
         this Section 9. The parties hereto further acknowledge that the scope
         and duration of the covenants set forth in this Section 9 are in all
         respects reasonable.

                  (d) The Company and the Partners acknowledge and agree that
         the breach by either of them of the provisions of this Section 9 could
         not be adequately compensated with monetary damages and would
         irreparably injure Purchaser, and, accordingly, that injunctive relief
         and specific performance shall be appropriate remedies to enforce the
         provisions of this Section against the Company and the Partners, and
         the Company and the Partners waive any claim or defense that there is
         an adequate remedy at law for such breach; provided, however, that
         nothing contained herein shall limit the remedies, legal or equitable,
         otherwise available to Purchaser, and all remedies of Purchaser herein
         are in addition to any remedies available to Purchaser at law or
         otherwise.

                  (e) The Partners acknowledge and recognize that the
         enforcement of any of the noncompetition provisions in this Agreement
         by Purchaser will not interfere with the Partners' ability to pursue a
         proper livelihood. The Partners further represent that they are capable
         of pursuing a career that would not violate the noncompetition
         provisions hereof to earn a proper livelihood. The Partners and the
         Company agree that due to the nature of such business, the
         noncompetition restrictions set forth in this Agreement are reasonable
         as to time and geographic area. At any time during the non-compete
         period, Purchaser may require the Partners and the Company to supply
         such information as Purchaser deems necessary to ascertain whether or
         not the Partners have complied with, or have violated, the covenants
         set forth in this Section 9. Any such request for information will be
         sent to the Partners and/or the Company by certified mail, return
         receipt requested, addressed to such person's last known address. The
         Partners and/or the Company shall furnish the requested information to
         Purchaser within 10 days following the receipt of such request.

         10. Post-Closing Covenants. Purchaser shall have no obligation to
repair or replace any products sold by the Company.

         11. Expenses. Purchaser, on the one hand, and the Company and the
Partners, on the other hand, will bear their own costs and expenses of the
transactions contemplated hereby (i.e., the Company will not pay any of such
costs or expenses prior to Closing and the Purchaser will not assume any
liability to pay any such costs and expenses of the Company or the Partners).


                                       -8-

         12. Further Assurances. At the Closing and after the Closing, each
party hereto shall take all actions and duly execute and deliver or cause to be
executed and delivered all instruments of sale, conveyance, transfer, assignment
or assumption, and all notices, releases, acquittances and other documents that
may be necessary or advisable to consummate the transactions contemplated in
this Agreement, or more fully to sell, convey, transfer, assign, and deliver to
and vest in Purchaser the Assets sold, conveyed, transferred, assigned, and
delivered by the Company pursuant hereto or intended so to be.

         13. Indemnification. The Company and the Partners shall, jointly and
severally, indemnify and hold Purchaser and its affiliates and the officers,
directors, partners, stockholders, employees and agents of Purchaser and its
affiliates harmless from and against any loss, damage, claim, demand, cause of
action, liability, costs or expense (including without limitation interest,
penalties, and attorneys' fees and disbursements) of any kind or nature
whatsoever asserted against or incurred by Purchaser or the Assets by reason of,
resulting from, or based upon: (a) any misrepresentation, breach of warranty or
breach or nonfulfillment of any covenant or other agreement made by them herein
or in any other agreement executed and delivered by them pursuant to this
Agreement, (b) the ownership, management, operation or use of the Assets and
business of the Company prior to the Closing; (c) liabilities or obligations
with respect to the Assets or the business of the Company or the operation
thereof with respect to the periods before the Closing (other than Assumed
Liabilities) including, but not limited to, claims relating to taxes due for
periods prior to the Closing; (d) occurrences of any nature prior to the Closing
relating to the Company's business or the Assets, whether such claims are
asserted prior to or after the Closing; and (e) any obligation or liability
relating to any employee benefit plan of the Company or relating to any employee
of the Company who is not hired by Purchaser. Any claim for indemnification
pursuant to this Section 13 must be asserted on or before five years after the
Closing Date.

NO INVESTIGATION BY OR ON BEHALF OF, AND NO NEGLIGENCE OF, PURCHASER OR ITS
AFFILIATES, NOR ANY INFORMATION THAT THEY MAY HAVE OR OBTAIN WILL AFFECT THE
INDEMNIFICATION OBLIGATIONS OF THE COMPANY AND THE PARTNERS HEREUNDER.

         14. Guarantee. Partners hereby jointly and severally unconditionally
guarantee to Purchaser and its affiliates the full and timely performance of all
of the obligations and agreements of the Company. The foregoing guarantee shall
include the guarantee of the payment of all damages, costs and expenses which
might become recoverable as a result of the breach or nonperformance by the
Company of any provision contained herein. The Purchaser and its affiliates may
proceed against any or all of the Partners for the performance of any such
obligation or agreement, or for damages for default in the performance thereof,
without first proceeding against the Company, the other Partners or against any
of their properties.

         15. Entire Agreement: Counterparts. This Agreement constitutes the
entire agreement among the parties pertaining to the subject matter hereof and
supersedes all other prior or contemporaneous agreements and understandings,
both oral and written, of the parties in connection therewith. This Agreement
may be executed in counterparts.

         16. Severability. If any term, provision, covenant or condition of this
Agreement is held by any court of competent jurisdiction to be invalid, void or
unenforceable in any respect, the remainder of such term, provision, covenant or
condition in every other respect and the remainder of this Agreement shall

Gentlemen:

         The purpose of this letter agreement (this "Agreement") is to set
forth the terms and conditions agreed to by and among BearCom Operating, L.P.,
a Texas limited partnership ("Purchaser"), Mobitel Communications and
Electronics, Inc., a Texas corporation ("Mobitel"), Network Communications,
Inc., a Texas corporation ("Network" and collectively with Mobitel, "Sellers"),
Royce A. Witte, one of the two shareholders of Mobitel and the sole shareholder
of Network ("Witte"), and James D. Reed, one of the two shareholders of Mobitel
("Reed") (Witte and Reed are sometimes collectively referred to herein as the
"Shareholders"), for Purchaser's purchase of certain assets of the Sellers.
For good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties hereto hereby agree as follows:

         1.      Sale of Assets.  At the Closing (hereinafter defined),
Purchaser will purchase and (a) Mobitel will sell, convey and assign to
Purchaser, free and clear of all liens, claims and encumbrances, all of the
business, assets, property and goodwill of Mobitel of every kind and character,
whether real or personal, tangible or intangible, (other than cash and accounts
receivable of Mobitel ("Receivables")) including (without limitation) all of
the fixed assets, inventory, two-way radios, intangible assets, customer data
and related information, permits, insurance proceeds (if any), computers, the
contracts set forth on Exhibit A hereto (the "Assumed Contracts"), records, the
name "Mobitel Communications and Electronics," the phone and fax numbers of
Mobitel, trademarks and trade names, and deposits and prepaid expenses, and (b)
Network will sell, convey and assign to Purchaser, free and clear of all liens,
claims and encumbrances, the rental two-way radios owned by Network that are
described on Exhibit D hereto (the assets listed under clauses (a) and (b) of
this sentence are collectively referred to herein as the "Assets").  Sellers
will be entitled, and Purchaser will not be obligated, to collect the
Receivables after the Closing; Purchaser would, however, remit to Sellers any
payment on the Receivables received by Purchaser.  SEE ADDENDUM.

         2.      Liabilities Not Assumed; Sales Tax.

                 (a)      Purchaser will not assume or be liable for any
         liabilities or obligations of the Sellers and the Sellers and the
         Shareholders will, jointly and severally, indemnify Purchaser against
         and hold it harmless from all such liabilities and obligations.  SEE
         ADDENDUM.

                 (b)      The liabilities and obligations of the Sellers that
         Purchaser will not assume include, but are not limited to, trade
         payables and other accounts payable, bank debt or other debts for
         borrowed money, pension, and other employee benefit plan liabilities
         (including any accruals relating thereto), breaches or violations of
         agreements to which the Sellers or the Assets are subject, violations
         of law or applicable statutory regulations, property damage, personal
         injury, negligence, sexual abuse or harassment or employee claims
         based on events occurring prior to the Closing Date, liabilities or
         obligations of the Sellers for employees' accrued vacations,
         liabilities or obligations to remediate or cleanup any contamination
         or pollution of the air, soil or other environmental conditions
         occurring or existing prior to the Closing Date, any contingent
         liabilities (whether or not known), any other liabilities or
         obligations that relate to the period, or conditions existing, before
         the Closing.

                 (c)      The Sellers shall be liable for and shall pay any
         sales tax and other similar taxes resulting from consummation of the
         transactions contemplated hereby.

         3.      Price for the Assets.     The purchase price for the Assets
(the "Purchase Price") shall be payable by Purchaser to the Sellers as follows:

                 (a)      [Confidential Treatment Requested with SEC] shall be 
         payable to Sellers by Purchaser check or wire transfer at the Closing.

                 (b)      [Confidential Treatment Requested with SEC] shall be 
         payable to Sellers by Purchaser check or wire transfer on the date that
         is six months after the Closing Date.

                 (c)      [Confidential Treatment Requested with SEC] shall be 
         payable to Sellers by Purchaser check or wire transfer on the first 
         anniversary of the Closing Date.

The cash that would be payable to Sellers pursuant to subsections (a), (b) and
(c) of this Section 2 shall be allocated between Mobitel and Network as set
forth on Exhibit B hereto.

         4.      Representations and Warranties.  The Sellers and the
Shareholders jointly and severally represent and warrant to Purchaser that the
following are true and correct as of the date hereof and that the following
will be true and correct as of the Closing Date:

                 (a)      The Shareholders are the sole shareholders of
         Mobitel, and Witte is the sole shareholder of Network.

                 (b)      The Assets include all of the assets reflected in the
         December 31, 1996 balance sheets of the Sellers previously delivered
         by the Sellers to Purchaser (other than inventory sold in the ordinary
         course of business since that date on a basis consistent with prior
         practices).  The inventory amounts on the December 31, 1996 balance
         sheets reflect the cost of such inventory.  The Sellers holds good and
         indefeasible title to the Assets, free and clear of all liens, claims
         and encumbrances.  At the





                                      -2-
<PAGE>   3
         Closing Purchaser will acquire good and indefeasible title to the
         Assets, free and clear of all liens, claims and encumbrances.

                 (c)      The Sellers have furnished to Purchaser the balance
         sheet and related statements of income, retained earnings, changes in
         stockholders' equity, and cash flows of the Sellers including the
         notes thereto at and for the period ending December 31, 1996
         (collectively, the "Financial Statements").  The Financial Statements
         fairly present the financial condition and results of operations of
         the Sellers as of the dates and for the periods indicated and have
         been prepared in conformity with generally accepted accounting
         principles ("GAAP") applied on a consistent basis with prior
         practices.  There were not any significant items of income or expense
         which were unusual or of a nonrecurring nature reflected in the
         Financial Statements.

                 (d)      Except for those liabilities and obligations incurred
         in the ordinary course of business consistent with prior practices
         since the date of the Financial Statements, the Financial Statements
         reflect all liabilities and obligations of the Sellers, accrued,
         contingent or otherwise (known or unknown and asserted or unasserted),
         arising out of transactions effected or events occurring on or prior
         to the Closing Date.  All allowances and reserves shown in the
         Financial Statements are appropriate, reasonable and sufficient to
         provide for expenses and losses thereby contemplated.  Neither of the
         Sellers is liable upon or with respect to, or obligated in any other
         way to provide funds in respect of or to guarantee or assume in any
         manner, any debt, obligation or dividend of any person, corporation,
         association, partnership, joint venture, trust or other entity.  The
         Sellers and each of the Shareholders knows of no basis for the
         assertion of any other claims or liabilities of any nature or in any
         amount.

                 (e)      This Agreement has been duly authorized, executed and
         delivered by the Sellers and the Shareholders and is a valid and
         binding agreement of the Sellers and the Shareholders, enforceable
         against each such party in accordance with its terms.

                 (f)      Neither the execution and delivery of this Agreement
         nor the consummation of the transactions contemplated herein violates
         any law, agreement, mortgage or other instrument or provision of law
         to which or under which the Sellers or the Shareholders are a party or
         bound.

                 (g)      Except for the consents set forth on Schedule 4(g)
         hereto, no consents or approvals are required for execution of this
         Agreement by the Sellers and the Shareholders or their consummation of
         the transactions contemplated herein.

                 (h)      There is no judicial, administrative or arbitral
         action, suit, proceeding (public or private), claim or demand pending
         or, to the knowledge of the Sellers and the Shareholders, threatened
         against the Sellers or their businesses.

                 (i)      The Sellers and their businesses are, and have been,
         in compliance with all applicable laws, rules, regulations,
         ordinances, licenses, permits and orders.  The Sellers have maintained
         all employee benefit plans and arrangements in accordance with all
         applicable laws, rules and regulations including the Internal Revenue
         Code of 1986, as amended, and the Employee Retirement Income Security
         Act of 1974, as amended, and have timely filed with all applicable
         regulatory authorities all applicable reports and returns required to
         be filed by them with respect to its employee benefit plans and
         arrangements.

                 (j)      The Sellers have no liabilities for federal, state or
         local taxes, including but not limited to income, estimated, sales,
         use, ad valorem, personal property, franchise, payroll, employment,
         social security, unemployment, and disability taxes.

                 (k)      The Sellers have not suffered any adverse change in
         its business, operations, financial condition or prospects from that
         heretofore represented to Purchaser or its affiliates, officers or
         representatives.

                 (l)      The distribution agreements between the Sellers and
         Motorola, Inc. ("Motorola Contract") and all other contracts, if any,
         being assigned by the Sellers to Purchaser pursuant hereto are in full
         force and effect.  Neither party to any such contract is in default
         under any of such contracts, and no event has occurred that would,
         with the passage of time, cause a default under any of such contracts.
         The Sellers have paid the other party to each such contract all
         amounts it owes them whether or not such amounts are yet due.  The
         Sellers have provided Purchaser with true, correct, and current copies
         of all such contracts.  There are no other contracts that are material
         to the Sellers' businesses.

                 (m)      Set forth in Schedule 4(m) hereto is a complete and
         accurate list of all employees of the Sellers, together with their
         dates of hire, positions and their annual salaries and other
         compensation.  The Sellers have not granted or become obligated to
         grant any increases in the wages or salary of, or paid or become
         obligated to pay any bonus or made or become obligated to make any
         similar payment to or grant any benefit to or on behalf of, any
         officer, employee or agent.  The Sellers have no direct or indirect,
         express or implied, obligation to pay severance or termination pay to
         any officer or employee of either of the Sellers or to pay any amounts
         to any consultant, agent or similar person or entity.  The Sellers and
         the Shareholders have no knowledge of any facts which would indicate
         that any employee of the Sellers will not accept employment with
         Purchaser on a basis no less favorable than that upon which such
         employee is currently employed by the Sellers.

                 (n)      All of the fixed assets (including but not limited to
         all equipment), owned or leased by the Sellers are in good condition
         and repair, fit for their intended use in the ordinary course of
         business, and conform in all respects with all applicable ordinances,
         regulations and other laws and there are no known latent defects
         therein.  All regular maintenance or service requirements, and product
         recalls, have been followed, installed, or otherwise implemented on
         and with respect to the Assets.  All inventory of the Sellers is in
         good, current, standard, and merchantable condition and is not
         obsolete or defective.  The inventory of the Sellers is properly
         recorded on the Financial Statements at the lower of cost (last
         in-first out) or market in accordance with GAAP.

                 (o)      The books of account of the Sellers have been kept
         accurately in the ordinary course of its business, the transactions
         entered therein represent bona fide transactions and the revenues,
         expenses, assets and liabilities of the Sellers have been properly
         recorded in such books.  The records are in good order, are complete,
         and have been maintained in accordance with sound business practices.

                 (p)      Since December 31, 1996, neither of the Sellers has
         (i) declared, paid or set aside for payment any dividend or
         distribution to its shareholder or shareholders, (ii) made any loan or
         advance to any shareholder, officer, director or employee, (iii)
         redeemed, purchased or otherwise acquired or sold or issued any of its
         capital stock or any right to acquire such capital stock, or (iv)
         increased the





                                      -4-
<PAGE>   5
         compensation of or paid or accrued any bonus to any employee other
         than in accordance with past established practices, and none of such
         actions will be taken after the date hereof until the consummation of
         the transactions contemplated hereby.

                 (q)      No shareholder, director, or officer of either of the
         Sellers, nor any person who is a spouse or descendant of such
         shareholder, director or officer, has any direct or indirect
         relationship with any customer or supplier of, or other contracting
         party with, either of the Sellers.

                 (r)      Neither the Sellers nor any Shareholder knows or has
         any reason to believe, or has received notice or information, that any
         supplier of the Sellers will cease or refuse to do business with
         Purchaser after the consummation of the transactions contemplated
         hereby in the same manner, and same amount, as previously conducted
         with the Sellers.  Neither the Sellers nor any Shareholder has
         received any notice of any disruption (including delayed deliveries or
         allocations by suppliers or service providers) in the availability of
         the products used by the Sellers, nor are the Sellers or any
         Shareholder aware of any facts which could lead the Sellers to believe
         that the Sellers or Purchaser will be subject to any such material
         disruption.  Neither the Sellers nor any Shareholder is aware of any
         condition (financial or otherwise) affecting any supplier that will,
         or could be reasonably expected to, now or in the future, reduce each
         such supplier's ability to do business with Purchaser in substantially
         the same manner and amount that each such supplier has done business
         with the Sellers during the period preceding this Agreement.  Set
         forth in Schedule 4(r) is a complete and accurate list and description
         of all volume discounts and other discounts provided by any supplier
         of the Sellers.

                 (s)      All information furnished to Purchaser by the Sellers
         or the Shareholders, whether or not herein or in any Exhibit or
         Schedule hereto, is true, correct, and complete.  Such information
         states all material facts required to be stated therein or necessary
         to make the statements therein, in light of the circumstances under
         which such statements are made, true, correct and complete in all
         material respects.  The Sellers and the Shareholders have made due
         inquiry and investigation concerning the matters to which
         representations and warranties of the Sellers and the Shareholders
         under this Agreement pertain and the Sellers and the Shareholders, and
         each of them, are unaware of any facts, events or circumstances which
         have not been disclosed to Purchaser which are material to the Assets,
         the businesses of the Sellers, or the Sellers.

The representations, warranties and covenants of the Sellers and the
Shareholders set forth in this Agreement shall survive execution and delivery
of this Agreement and the Closing.

         5.      Closing.  The closing of the transactions contemplated hereby
(the "Closing") will take place concurrently with the execution of this
Agreement at the offices of Mobitel (or such other place as may be mutually
agreed upon by the parties hereto).  The day on which the Closing occurs is
herein referred to as the "Closing Date."

         6.      Deliveries at Closing.    At the Closing,

                 (a)      the Sellers shall execute and deliver to Purchaser
         bills of sale in the form reasonably requested by Purchaser and shall
         deliver a list of the fixed assets, inventory and rental two-way
         radios owned by the Sellers as of the Closing;





                                      -5-
<PAGE>   6
                 (b)      Purchaser shall deliver [Confidential Treatment
         Requested with SEC] to the Sellers (as so designated on Exhibit B 
         hereto) by Purchaser check or wire transfer;

                 (c)      counsel to the Sellers shall deliver to Purchaser a
         legal opinion dated the Closing Date in form reasonably acceptable to
         Purchaser opining to the matters set forth in Exhibit C hereto;

                 (d)      the Sellers shall deliver evidence of receipt of all
         required approvals, consents, licenses and permits, including without
         limitation the consent of Motorola Inc. to the transactions
         contemplated herein in a form acceptable to the Purchaser in its sole
         discretion; and

                 (e)      the Sellers shall execute and deliver such other
         documents as are reasonably requested by Purchaser to effectuate the
         purposes and intent of this Agreement.

         7.      Purchase Price Allocation.  The parties hereto hereby agree
that, for all accounting and foreign, federal, state and local tax reporting
purposes, the Purchase Price shall be allocated in accordance with the relative
fair market values of the Assets and the non-competition covenant set forth in
Section 9 hereof, as determined by Purchaser, as soon as practicable after the
Closing Date.  Purchaser shall provide to the Sellers a schedule setting forth
such allocation as soon as practicable after the Closing Date, and shall
thereafter notify the Sellers of any changes thereto.  Each of the parties
hereto hereby covenants and agrees that it will not take a position on any tax
return, before any governmental agency charged with the collection of any tax,
or in any judicial proceeding that is in any way inconsistent with the terms of
this Section 7.

         8.      Confidentiality.  The Sellers and the Shareholders agree to
hold in confidence the terms of this Agreement and, except as required by law,
will not make the same available or known to any third party other than their
counsel, accountants and other agents or representatives acting on their
behalf, and then only to the extent necessary, provided each such person is
advised of the confidential nature of the terms hereof and agrees to hold the
same in confidence.

         9.      Noncompetition and Non-solicitation.

                 (a)      For a period of three years after the Closing, and
         except for services performed on behalf of Purchaser, the Sellers and
         the Shareholders agree that neither they nor any of their affiliates
         will directly or indirectly either as an individual, a partner or a
         joint venturer, or in any other capacity, (i) invest (other than
         investments in publicly-owned companies which constitute not more than
         1% of the voting securities of any such company), or engage in, within

         extent necessary to be enforceable and to give effect to the intent of
         this Section 9.  SEE ADDENDUM.

                 (b)      For a period of three years after the Closing,
         neither the Sellers nor the Shareholders will, directly or indirectly,
         (i) except on behalf of Purchaser, solicit for any purpose, any
         customer of Purchaser (or former customer of Sellers), (ii) solicit
         for employment by the Sellers or anyone else, any employee of
         Purchaser or its affiliates as a result of the transactions
         contemplated hereby or any person who was an employee of the Sellers
         or Purchaser or its affiliates within the four-month period
         immediately preceding such solicitation or employment, other than such
         person whose employment was terminated by Purchaser or its affiliates;
         or (iii) induce or attempt to induce, any such employee of Purchaser
         or its affiliates to terminate such employee's employment.

                 (c)      The parties hereto acknowledge that the provisions of
         this Section 9 are supported by good and valuable consideration and
         Purchaser's agreement to consummate the transactions contemplated
         hereby are conditioned upon its receipt of the protection provided in
         this Section 9.  The parties hereto further acknowledge that the scope
         and duration of the covenants set forth in this Section 9 are in all
         respects reasonable.

                 (d)      The Sellers and the Shareholders acknowledge and
         agree that the breach by either of them of the provisions of this
         Section 9 could not be adequately compensated with monetary damages
         and would irreparably injure Purchaser, and, accordingly, that
         injunctive relief and specific performance shall be appropriate
         remedies to enforce the provisions of this Section against the Sellers
         and the Shareholders, and the Sellers and the Shareholders waive any
         claim or defense that there is an adequate remedy at law for such
         breach; provided, however, that nothing contained herein shall limit
         the remedies, legal or equitable, otherwise available to Purchaser,
         and all remedies of Purchaser herein are in addition to any remedies
         available to Purchaser at law or otherwise.

                 (e)      The Shareholders acknowledge and recognize that the
         enforcement of any of the noncompetition provisions in this Agreement
         by Purchaser will not interfere with the Shareholders' ability to
         pursue a proper livelihood.  The Shareholders further represent that
         they are capable of pursuing a career that would not violate the
         noncompetition provisions hereof to earn a proper livelihood.  The
         Shareholders and the Sellers agree that due to the nature of such
         business, the noncompetition restrictions set forth in this Agreement
         are reasonable as to time and geographic area.  At any time during the
         non-compete period, Purchaser may require the Shareholders and the
         Sellers to supply such information as Purchaser deems necessary to
         ascertain whether or not the Shareholders and the Sellers have
         complied with, or have violated, the covenants set forth in this
         Section 9.  Any such request for information will be sent to the
         Shareholders and/or the Sellers by certified mail, return receipt
         requested, addressed to such person's last known address.  The
         Shareholders and/or the Sellers shall furnish the requested
         information to Purchaser within 10 days following the receipt of such
         request.

         10.     Employment Arrangement.  Purchaser would employ Reed beginning
immediately after the Closing.  That employment relationship would be at-will
and in accordance with Purchaser's employment policies and procedures.

         11.     Repairs.  Purchaser shall have no obligation to repair or
replace any products sold by the Sellers.  Nonetheless, if Purchaser, in its
sole discretion, chooses to repair or replace any product sold by the





                                      -7-

each party hereto shall take all actions and duly execute and deliver or cause

contemplated in this Agreement, or more fully to sell, convey, transfer,
assign, and deliver to and vest in Purchaser the Assets sold, conveyed,
transferred, assigned, and delivered by the Sellers pursuant hereto or intended
so to be.

         14.     Indemnification.  The Sellers and the Shareholders shall,
jointly and severally, indemnify and hold Purchaser and its affiliates and the
officers, directors, partners, stockholders, employees and agents of Purchaser
and its affiliates harmless from and against any loss, damage, claim, demand,
cause of action, liability, costs or expense (including without limitation

not limited to, claims relating to taxes due for periods prior to the Closing;
(d) occurrences of any nature prior to the Closing relating to the Sellers'
businesses or the Assets, whether such claims are asserted prior to or after

plan of either Seller or relating to any employee of either Seller who is not
hired by Purchaser, and (f) any obligation or liability for any finders',

AFFILIATES, NOR ANY INFORMATION THAT THEY MAY HAVE OR OBTAIN WILL AFFECT THE

         15.     Purchaser's Right Of Offset.  Purchaser shall be entitled to

     hereunder shall give to the party obligated to provide indemnification to
     such Indemnified Party (the "Indemnitor") a notice (a "Claim Notice")
     describing in reasonable detail the facts giving rise to any claim for
     indemnification hereunder and shall include in such Claim Notice (if then
     known) the amount or the method of computation of the amount of such 
     claim, and a reference to the provision of this Agreement or any other
     agreement, document or 


                                    Page 8



<PAGE>   9
instrument executed hereunder or in connection herewith upon which such claim
is based; provided, that a Claim Notice in respect of any action at law or suit
in equity by or against a third person as to which indemnification will be
sought shall be given promptly after the action or suit is commenced; provided
further, that failure to give such notice shall not relieve the Indemnitor of
its obligations hereunder except to the extent it shall have been prejudiced by
such failure.

     (b) In calculating any Loss there shall be deducted (i) any insurance
recovery in respect thereof (and no right of subrogation shall accrue hereunder
to any insurer) and (ii) the amount of any tax benefit to the Indemnified Party
with respect to such Loss or Expense (after giving effect to the tax effect of
receipt of the indemnification payments).

     (c) After the giving of any Claim Notice pursuant hereto, the amount of
indemnification to which an Indemnified Party shall be entitled under this
Article VII shall be determined: (i) by the written agreement between the
Indemnified Party and the Indemnitor; (ii) by a final judgment or decree of any
court of competent jurisdiction, or (iii) by any other means to which the
Indemnified Party and the Indemnitor shall agree. The judgment or decree of a
court shall be deemed final when the time for appeal, if any, shall have
expired and no appeal shall have been taken or when all appeals taken shall
have been finally determined. The Indemnified Party shall have the burden of
proof in establishing the amount of Loss suffered by it.

7.5. THIRD PERSON CLAIMS.

     (a) Subject to Section 7.5(b), the Indemnified Party shall have the right
to conduct and control, through counsel of its choosing, the defense,
compromise or settlement of any third person claim, action or suit against such
Indemnified Party as to which indemnification will be sought by any Indemnified
Party from any Indemnitor hereunder, and in any such case the Indemnitor shall
cooperate in connection therewith and shall furnish such records, information
and testimony and attend such conferences, discovery proceedings, hearings,
trials and appeals as may be reasonably requested by the Indemnified Party in
connection therewith; provided, that the Indemnitor may participate, through
counsel chosen by it and at its own expense, in the defense of any such claim,
action or suit as to which the Indemnified Party has so elected to conduct and
control the defense thereof; and provided, further, that the Indemnified Party
shall not, without the written consent of the Indemnitor (which written consent
shall not be unreasonably withheld), pay, compromise or settle any such claim,
action or suit, except that no such consent shall be required if, following a
written request from the Indemnified Party, the Indemnitor shall fail, within
14 days after the making of such request, to acknowledge and agree in writing
that, if such claim, action or suit shall be adversely determined, such
Indemnitor has an obligation to provide indemnification hereunder to such
Indemnified Party. Notwithstanding the foregoing, the Indemnified Party shall
have the right to pay, settle or compromise any such claim, action or suit
without such consent, provided that in such event the Indemnified Party shall
waive any right to indemnity hereunder unless such consent is unreasonably
withheld.

     (b) If any third person claim, action or suit against any Indemnified
Party is solely for money damages or, where Seller is the Indemnitor, will have
no continuing effect in any material respect on the Purchased Assets, then the
Indemnitor shall have the right to conduct and control, through counsel of its
choosing, the defense, compromise or settlement of any such third person claim,
action or suit against such Indemnified Party from any Indemnitor hereunder if
the Indemnitor has acknowledged and agreed in writing that, if the same is
adversely determined, the Indemnitor has an obligation to provide
indemnification to the Indemnified Party in respect thereof, and in any such
case the Indemnified Party shall cooperate in connection therewith and shall
furnish such records, information and testimony and attend such conferences,
discovery proceedings, hearings, trials and appeals 




                                    Page 9


<PAGE>   10
     as may be reasonably requested by the Indemnitor in connection therewith;
     provided, that the Indemnified Party may participate, through counsel,
     chosen by it and at its own expense, in the defense of any such claim,
     action or suit as to which the Indemnitor has so elected to conduct and
     control the defense thereof. Notwithstanding the foregoing, the
     indemnified party shall have the right to pay, settle or compromise any
     such claim, action or suit, provided that in such event the Indemnified
     party shall waive any right to indemnity therefor hereunder unless the
     Indemnified Party shall have sought the consent of the Indemnitor to such
     payment, settlement or compromise and such consent was unreasonably
     withheld, in which event no claim for indemnity therefor hereunder shall
     be waived.

     7.6. THRESHOLD AND EXCLUSIVITY.

          (a)  Seller shall not be liable and Buyer agrees not to enforce any
     claim for indemnification under this Agreement until the aggregate of all
     such claims exceeds $50,000 (the "Threshold Amount"), and then the Buyer
     shall be entitled to recover only the amount of such claims in excess of
     the Threshold Amount. Buyer shall provide Seller with a notice of all
     claims included in the Threshold Amount. the maximum liability of Seller
     for all claims and damages of every kind and character arising under or
     in connection with this Agreement and the transactions contemplated
     hereby, including indemnification, shall be an amount equal to the
     Purchase Price. Claims for indemnification in excess of the Threshold
     Amount shall be made only in increments of $2,500 or more, and claims
     relating to similar products or constituting like claims may be aggregated
     in determining the $2,500 amount.

          (b)  Indemnification pursuant to this Article VII shall be the sole
     and exclusive remedy for any claim for monetary damages resulting from a
     breach of any representation or warranty under this Agreement, the
     Schedules hereto and any certificate delivered pursuant hereto.

of this Agreement to the same extent as if they were set forth verbatim herein.

     8.7. WAIVERS. Any term or provision of this Agreement may be waived, or
the time for its performance may be extended, by the party or parties entitled
to the benefit thereof. Any such waiver shall be validly and sufficiently
authorized for the purposes of this Agreement if, as to any party, it is
authorized in writing by an authorized representative of such party. The
failure of any party hereto to enforce at any time any provision of this
Agreement shall not be construed to be a waiver of such provision, nor in any
way to affect the validity of this Agreement or any part hereof or the right of
any party thereafter to enforce each and every such provision. No waiver of any
breach of this Agreement shall be held to constitute a waiver of any other or
subsequent breach.

     8.8. EXPENSES. Each party hereto will pay all costs and expenses incident
to its negotiation and preparation of this Agreement and to its performance and
compliance with all agreements and conditions contained herein on its part to
be performed or complied with, including the fees, expenses and disbursements
of its counsel and accountants.

     8.9. PARTIAL INVALIDITY. Wherever possible, each provision hereof shall be
interpreted in such manner as to be effective and valid under applicable law,
but in case any one or more of the provisions contained herein shall, for any
reason, be held to be invalid, illegal or unenforceable in any respect, such
provision shall be ineffective to the extent, but only to the extent, of such
invalidity, illegality or unenforceability without invalidating the remainder
of such invalid, illegal or unenforceable provision or provisions or any other
provisions hereof, unless such a construction would be unreasonable.

     8.10. EXECUTION IN COUNTERPARTS. This Agreement may be executed in one or
more counterparts, each of which shall be considered an original instrument,
but all of which shall be considered one and the same agreement, and shall
become binding when one or more counterparts have been signed by each of the
parties hereto and delivered to each of Seller and Buyer.

     8.11. GOVERNING LAW AND DISPUTE RESOLUTION. This Agreement shall be
governed by and construed in accordance with the internal laws (as opposed to
the conflicts of law provisions) of the State of Illinois. Seller and Buyer
will attempt to settle any claim or controversy arising out of this Agreement
through consultation and negotiation in good faith and a spirit of mutual
cooperation. If those attempts fail, then the dispute will be mediated by a
mutually-acceptable mediator to be chosen by Seller and Buyer within 45 days
after written notice by one of the parties demanding mediation. Neither party
may unreasonably withhold consent to the selection of a mediator, and Seller
and Buyer will share the costs of the mediation equally. By mutual agreement,
however, Seller and Buyer may postpone mediation until each has completed some
specified but limited discovery about the dispute. The parties may also agree
to replace mediation with some other form of alternative dispute resolution
(ADR), such as neutral fact-finding or a minitrial.

     Any dispute which cannot resolve by the parties through negotiation,
mediation or other form of ADR within six months of the date of the initial
demand for it by one of the parties hereto may then be submitted to the courts
within the State of Illinois for resolution (as provided in Section 8.12
below). The use of any ADR procedures will not be construed under the doctrines
of laches, waiver or estoppel to affect adversely the rights of either party.
Nothing in this section will prevent either party from resorting to judicial
proceedings if (a) good faith efforts to resolve the dispute under these
procedures have been unsuccessful or (b) interim relief from a court is
necessary to prevent serious and irreparable injury to one party or to others.

     8.12. SUBMISSION TO JURISDICTION. Seller and Buyer hereby irrevocable
submit in any suit, action or proceeding arising out of or relate to this
Agreement or any of the transactions contemplated hereby or thereby to the
jurisdiction of the United States District Court for the Northern District of
Illinois and the jurisdiction of any court of the State of Illinois located in
Chicago and waive any and all objections to jurisdiction that they may have
under the laws of the State of Illinois or the United States.

     8.13. BULK TRANSFER. Buyer hereby waives compliance by Seller with all
applicable bulk transfer, bulk sales and similar laws and requirements of all
jurisdictions in connection with the transactions contemplated hereby. Seller
shall indemnify and hold harmless Buyer against any and all expense, loss or
damage which Buyer may suffer as a result of claims asserted by third parties
against Buyer due to any noncompliance by Seller with applicable bulk transfer
laws.

Gentlemen:

         The purpose of this letter agreement (this "Agreement") is to set
forth the terms and conditions agreed to by and among Bear Communications,
Inc., a California corporation ("Purchaser"), Alfred Fasano ("Fasano"), Tedco,
Inc.  ("Tedco")(Fasano and Tedco are sometimes collectively referred to herein
as the "Shareholders"), David J. Broser, Susan Broser Guttentag, Mindy Broser
Cepelewicz and Lori Broser Furnari (David J. Broser, Susan Broser Guttentag,
Mindy Broser Cepelewicz and Lori Broser Furnari, being the owners of all of the
capital stock of Tedco, are sometimes collectively referred to herein as the
"Tedco Shareholders") for Purchaser's purchase of all of the capital stock (the
"Shares") of Cellular City, Inc. (fka Convention Communications, Inc.), a
Nevada corporation (the "Company").  For good and valuable consideration, the
receipt and adequacy of which are hereby acknowledged, the parties hereto
hereby agree as follows:

         1.      Sale of Shares.  At the Closing (hereinafter defined),
Purchaser will purchase and the Shareholders will sell, convey and assign the
Shares, free and clear of all liens, claims and encumbrances.

         2.      Price for the Assets. The purchase price for the Shares (the
"Purchase Price") shall be [Confidential Treatment Requested with SEC] and shall
be payable by Purchaser to the Shareholders by wire transfers at the Closing.
The Purchase Price will be divided between the Shareholders based on their share
ownership as set forth in Section 3(b) hereof.

         3.      Representations and Warranties of the Shareholders.  The
Shareholders jointly and severally represent and warrant to Purchaser that the
following are true and correct as of the date hereof and that the following
will be true and correct as of the Closing Date:

                 (a)      The Company is a corporation duly organized, validly
         existing and in good standing under the laws of the State of Nevada
         with all requisite power and authority to carry on the business in
         which it is now engaged and to own and lease the properties it now
         owns and leases.  The Company is qualified to do business as a foreign
         corporation in Illinois.  The Company is not
<PAGE>   2
         required to be qualified to conduct business in any jurisdiction other
         than the States of Nevada and Illinois.  Tedco is a corporation duly
         organized, validly existing and in good standing under the laws of the
         State of Nevada, with all requisite power and authority to execute and
         deliver this Agreement and perform its obligations hereunder.

                 (b)      The authorized capital stock of the Company consists
         of 2,500 shares of Common Stock, of which 700 shares are issued and
         outstanding and no shares are held in treasury.  The outstanding
         Common Stock is held of record and beneficially as follows:  Fasano
         (336 shares) and Tedco (364 shares).  All of the outstanding shares of
         capital stock of the Company have been duly authorized and validly
         issued, are fully paid and nonassessable, and none have been issued or
         disposed of in violation of the preemptive rights of any current or
         former shareholder.  There are no outstanding securities convertible
         into or exchangeable for capital stock of the Company.  There are no
         outstanding options, warrants or other rights to acquire, or any
         plans, contracts or commitments providing for the issuance of or the
         right to acquire (i) any capital stock of the Company or (ii) any
         securities convertible into or exchangeable for the capital stock of
         the Company.

                 (c)      The Shareholders are the sole record and beneficial
         owners of all of the outstanding capital stock of the Company, free
         and clear of all liens, claims, encumbrances and proxies.  At the
         Closing, Purchaser will acquire good and indefeasible title to the
         Shares, free and clear of all liens, claims, encumbrances and proxies
         other than those created by Purchaser, if any.

                 (d)      Each Shareholder has the capacity, power and
         authority to transfer the Shares owned by him or it without the
         consent of any other person.  Each Shareholder has the sole right to
         vote or direct the voting of the shares of capital stock of the
         Company owned by him or it, at his or its discretion, on any matter
         submitted to a vote of shareholders of the Company.

                 (e)      The copies of the Articles of Incorporation and
         Bylaws, and all amendments thereto, of the Company that have been
         delivered to Purchaser are true, correct and complete copies thereof.
         The minute books of the Company, copies of which have been provided to
         Purchaser, contain complete and accurate minutes of all meetings of
         and accurate consents to all actions taken without meetings by the
         Board of Directors (and any committee thereof) and the shareholders of
         the Company since the formation of the Company.  There are no
         outstanding applications or filings that would alter in any way the
         charter documents or corporate status of the Company; no bylaws have
         been passed, enacted, consented to or adopted by the directors or
         shareholders of the Company except those contained in the minute books
         of the Company.

                 (f)      The Company owns all of the assets reflected in the
         October 31, 1996 balance sheet of the Company previously delivered by
         the Shareholders to Purchaser, along with property acquired by the
         Company since October 31, 1996 .  The inventory amounts on the October
         31, 1996 balance sheet reflect the cost of such inventory.  Set forth
         on Schedule 3(f) is a true and correct list of all fixed assets and
         rental cellular phones owned by Company.  The Company holds good and
         indefeasible title to all of its assets, free and clear of all liens,
         claims and encumbrances.  The assets owned and leased by the Company
         constitute all of the assets, property and goodwill of every kind and
         character used in the business of the Company.

                 (g)      The Shareholders have furnished to Purchaser the
         audited balance sheet and related statements of operations, and cash
         flows of the Company including the notes thereto at and for the





                                       2
<PAGE>   3
         period ending October 31, 1996 (the "Audited Financial Statements")
         and the unaudited balance sheet and related statements of operations,
         and cash flows of the Company at and for the period ending July 31,
         1997 (the "Unaudited Financial Statements," and collectively, with the
         Audited Financial Statements, the "Financial Statements").  The
         Financial Statements fairly present the financial condition and
         results of operations of the Company as of the dates and for the
         periods indicated and have been prepared in conformity with generally
         accepted accounting principles ("GAAP") applied on a consistent basis
         with prior practices.  There were not any significant items of income
         or expense which were unusual or of a nonrecurring nature reflected in
         the Financial Statements.

                 (h)      Except for those liabilities and obligations incurred
         in the ordinary course of business consistent with prior practices
         since the date of the Financial Statements, none of which are
         material, the Financial Statements reflect all liabilities and
         obligations of the Company, accrued, contingent or otherwise (known or
         unknown and asserted or unasserted), arising out of transactions
         effected or events occurring on or prior to the Closing Date.  All
         allowances and reserves shown in the Financial Statements are
         appropriate, reasonable and sufficient to provide for expenses and
         losses thereby contemplated.  The Company is not liable upon or with
         respect to, or obligated in any other way to provide funds in respect
         of or to guarantee or assume in any manner, any debt, obligation or
         dividend of any person, corporation, association, partnership, joint
         venture, trust or other entity.  The Company and each of the
         Shareholders know of no basis for the assertion of any other claims or
         liabilities of any nature or in any amount.

                 (i)      This Agreement has been duly authorized, executed and
         delivered by the Shareholders and is a valid and binding agreement of
         the Shareholders, enforceable against each such party in accordance
         with its terms.

                 (j)      Neither the execution and delivery of this Agreement
         nor the consummation of the transactions contemplated herein violates
         any law, agreement, mortgage or other instrument or provision of law
         to which or under which the Company or the Shareholders are a party or
         bound.

                 (k)      Except for the consents set forth on Schedule 3(k)
         hereto, no consents or approvals are required for execution of this
         Agreement by the Shareholders or their consummation of the
         transactions contemplated herein.

                 (l)      There is no judicial, administrative or arbitral
         action, suit, proceeding (public or private), claim or demand pending
         or threatened against the Company or its business.

                 (m)      The Company and its business are, and have been, in
         compliance with all applicable laws, rules, regulations, ordinances,
         licenses, permits and orders.  The Company does not have any employee
         benefit plans other than a group health insurance plan.  The Company
         has paid all amounts due pursuant to the health insurance plan.  The
         Company has maintained all employee benefit plans and arrangements in
         accordance with all applicable laws, rules and regulations including
         the Internal Revenue Code of 1986, as amended, and the Employee
         Retirement Income Security Act of 1974, as amended, and have timely
         filed with all applicable regulatory authorities all applicable
         reports and returns required to be filed by them with respect to its
         employee benefit plans and arrangements.

                 (n)      Except as explicitly disclosed in the July 31, 1997
         balance sheet delivered by the Shareholders to the Purchaser, the
         Company has no liabilities for federal, state or local taxes,
         including but not limited to income, estimated, sales, use, ad
         valorem, personal property, franchise, payroll, employment, social
         security, unemployment, and disability taxes.  The Company has duly
         and timely filed all tax returns required to be filed by or on behalf
         of it pursuant to any applicable federal, state or local law for all
         years and periods for which such tax returns have become due.  All
         such tax returns were correct and complete.  All taxes owed by the
         Company or required to be withheld or collected by the Company and
         paid to a taxing authority have been paid to the appropriate taxing
         authority, or if they are not yet required to be paid to the
         appropriate taxing authority, have been set aside in accounts for such
         purpose or have been reserved on the books of account of the Company.
         The Company has never filed an election to be treated as an S
         corporation in accordance with the provisions of Section 1362(a) of
         the Internal Revenue Code.

                 (o)      The Company has not suffered any adverse change in
         its business, operations, financial condition or prospects from that
         heretofore represented to Purchaser or its affiliates, officers or
         representatives.  Since the date of the Audited Financial Statements,
         the Company has conducted its business in the ordinary and normal
         course consistent with past practices including the payment of
         payables in a timely manner.

                 (p)      Schedule 3(p) hereto sets forth all contracts to
         which the Company is a party (the "Contracts").  The Company has
         provided Purchaser with true, correct, and current copies of the
         Contracts other than the Nevada lease, which the Company can not find.
         All of the Contracts are in full force and effect.  Neither party to
         any Contract is in default under any of such Contract, and no event
         has occurred that would, with the passage of time, cause a default
         under any of such Contracts.  The Company has paid the other party to
         each such Contract all amounts it owes them.  The lease to which the
         Company is a party in Nevada is a month to month lease.  The Company
         does not have a lease in Illinois.

                 (q)      Set forth in Schedule 3(q) hereto is a complete and
         accurate list of all employees of the Company, together with their
         dates of hire, positions and their annual salaries and other
         compensation.  The Company has not granted or become obligated to
         grant any increases in the wages or salary of, or paid or become
         obligated to pay any bonus or made or become obligated to make any
         similar payment to or grant any benefit to or on behalf of, any
         officer, employee or agent.  The Company has no direct or indirect,
         express or implied, obligation to pay severance or termination pay to
         any officer or employee of the Company or to pay any amounts to any
         consultant, agent or similar person or entity.  The Company and the
         Shareholders have no knowledge of any facts which would indicate that
         any employee of the Company will not remain employed by the Company or
         Purchaser on a basis no less favorable than that upon which such
         employee is currently employed by the Company.  The Company is not a
         party to any collective bargaining agreement or the subject of any
         union organization effort, and there are not any pending or threatened
         strikes, labor disputes, slow downs or stoppages pending or threatened
         against the Company.

                 (r)      All of the fixed assets (including but not limited to
         all equipment), owned or leased by the Company are in good condition
         and repair (reasonable wear and tear excepted), fit for their intended
         use in the ordinary course of business, and conform in all respects
         with all applicable ordinances, regulations and other laws and there
         are no known latent defects therein.  To the best of the Company's
         knowledge all regular maintenance or service requirements, and product
         recalls,





                                       4
<PAGE>   5
         have been followed, installed, or otherwise implemented on and with
         respect to the fixed assets.  All inventory of the Company is in good,
         current, standard, and merchantable condition and is not defective.
         The inventory of the Company is properly recorded on the Financial
         Statements at the lower of cost (last in-first out) or market in
         accordance with GAAP.

                 (s)      All patents, trademarks, trade names, service marks,
         copyrights and other proprietary rights ("Proprietary Rights") which
         the Company owns or uses are listed in Schedule 3(s) hereto.  The
         Company has a valid right to use all of such Proprietary Rights
         without conflict with the rights of others.  No person has made or
         threatened to make any claim that the operations of the Company are in
         violation of or infringe upon any Proprietary Right of any other
         person.

                 (t)      The books of account of the Company have been kept
         accurately in the ordinary course of its business, the transactions
         entered therein represent bona fide transactions and the revenues,
         expenses, assets and liabilities of the Company have been properly
         recorded in such books.  The records are in good order, are complete,
         and have been maintained in accordance with sound business practices.

                 (u)      Set forth in Schedule 3(u) hereto is a complete and
         accurate list and description of all accounts receivable of the
         Company's business from sales made as of July 31, 1997, and the
         payments and rights to receive payments related thereto.  All of the
         accounts receivable are free and clear of any security interests,
         liens, encumbrances, or other charges; none of such accounts
         receivable are subject to any offsets or claims of offsets; and none
         of the obligors of the accounts receivable have given notice that they
         will or may refuse to pay the full amount thereof or any portion
         thereof.  All accounts receivable will be collected in the usual and
         ordinary course of business within 90 days after the Closing assuming
         Purchaser undertakes reasonable efforts to collect such receivables.

                 (v)      Since October 31, 1996, the Company has not (i)
         declared, paid or set aside for payment any dividend or distribution
         to its shareholder or shareholders, (ii) made any loan or advance to
         any shareholder, officer, director or employee, (iii) redeemed,
         purchased or otherwise acquired or sold or issued any of its capital
         stock or any right to acquire such capital stock, (iv) increased the
         compensation of or paid or accrued any bonus to any employee other
         than in accordance with past established practices, or (v) except as
         described on Schedule 3(v) hereto, paid any management or consulting
         fee or any other amounts to any Shareholder, Worldwide Communications,
         Inc. or any other person related to or affiliated with the Company,
         any Shareholder or any employee of the Company, and none of such
         actions will be taken after the date hereof until the consummation of
         the transactions contemplated hereby.

                 (w)      No shareholder, director, or officer of the Company,
         nor any person who is a spouse or descendant of such shareholder,
         director or officer, has any direct or indirect relationship with any
         customer or supplier of, or other contracting party with, the Company.

                 (x)      Neither the Company nor any Shareholder knows or has
         any reason to believe, or has received notice or information, that any
         supplier of the Company or any other party that does business with the
         Company will cease or refuse to do business with the Company or
         Purchaser after the consummation of the transactions contemplated
         hereby in the same manner, and same amount, as previously conducted
         with the Company.  Neither the Company nor any Shareholder has
         received





                                       5

         any notice of any disruption (including delayed deliveries or
         allocations by suppliers or service providers) in the availability of
         the products used by the Company, nor are the Company or any
         Shareholder aware of any facts which could lead the Company to believe
         that the Company or Purchaser will be subject to any such material
         disruption.  Neither the Company nor any Shareholder is aware of any
         condition (financial or otherwise) affecting any supplier or any other
         party that does business with the Company that will, or could be
         reasonably expected to, now or in the future, reduce each such party's
         ability to do business with Purchaser in substantially the same manner
         and amount that each such party has done business with the Company
         during the period preceding this Agreement.  Set forth in Schedule
         3(x) is a complete and accurate list and description of all volume
         discounts and other discounts provided by any supplier of the Company
         or other party.

                 (y)      No Shareholder knows or has any reason to believe, or
         has received notice or information, that any customer of the Company
         will cease or refuse to do business with the Company or Purchaser
         after the consummation of the transactions contemplated hereby in the
         same manner, and same amount, as previously conducted with the
         Company.  The Company does not have any customers that constituted 5%
         or more of the Company's revenues for the twelve-month period ended
         July 31, 1997.

                 (z)      All information furnished to Purchaser by the Company
         or the Shareholders, whether or not herein or in any Exhibit or
         Schedule hereto, is true, correct, and complete.  Such information
         states all material facts required to be stated therein or necessary
         to make the statements therein, in light of the circumstances under
         which such statements are made, true, correct and complete in all
         material respects.  The Shareholders have made due inquiry and
         investigation concerning the matters to which representations and
         warranties of the Shareholders under this Agreement pertain and the
         Company and the Shareholders, and each of them, are unaware of any
         facts, events or circumstances which have not been disclosed to
         Purchaser which are material to the financial condition, results of
         operations, business or prospects of the Company.

The representations, warranties and covenants of the Shareholders set forth in
this Agreement shall survive execution and delivery of this Agreement and the
Closing.

         4.      Representations and Warranties of the Tedco Shareholders.  The
Tedco Shareholders jointly and severally represent and warrant to Purchaser
that the following are true and correct as of the date hereof and that the
following will be true and correct as of the Closing Date:

                 (a)      The authorized capital stock of the Company consists
         of 2,500 shares of Common Stock, of which 700 shares are issued and
         outstanding and no shares are held in treasury.  The outstanding
         Common Stock is held of record and beneficially as follows:  Fasano
         (336 shares) and Tedco (364 shares).  All of the outstanding shares of
         capital stock of the Company have been duly authorized and validly
         issued, are fully paid and nonassessable, and none have been issued or
         disposed of in violation of the preemptive rights of any current or
         former shareholder.  There are no outstanding securities convertible
         into or exchangeable for capital stock of the Company.  There are no
         outstanding options, warrants or other rights to acquire, or any
         plans, contracts or commitments providing for the issuance of or the
         right to acquire (i) any capital stock of the Company or (ii) any
         securities convertible into or exchangeable for the capital stock of
         the Company.





                                       6
<PAGE>   7
                 (b)      The Shareholders are the sole record and beneficial
         owners of all of the outstanding capital stock of the Company, free
         and clear of all liens, claims, encumbrances and proxies.  At the
         Closing, Purchaser will acquire good and indefeasible title to the
         Shares, free and clear of all liens, claims, encumbrances and proxies.
         The Tedco Shareholders are the sole record and beneficial owners (and
         have been for at least one year prior to the date hereof) of all of
         the capital stock of Tedco, securities convertible into or
         exchangeable for capital stock of Tedco, and all options, warrants or
         other rights to acquire the foregoing.

                 (c)      Tedco has, and to the best knowledge of Tedco and the
         Tedco Shareholders Fasano has, the capacity, power and authority to
         transfer the Shares owned by him or it without the consent of any
         other person.  Tedco has, and to the best knowledge of Tedco and the
         Tedco Shareholders Fasano has, the sole right to vote or direct the
         voting of the shares of capital stock of the Company owned by him or
         it, at his or its discretion, on any matter submitted to a vote of
         shareholders of the Company.

                 (d)      The Shareholders have furnished to Purchaser the
         audited balance sheet and related statements of operations, and cash
         flows of the Company including the notes thereto at and for the period
         ending October 31, 1996 (the "Audited Financial Statements") and the
         unaudited balance sheet and related statements of operations, and cash
         flows of the Company at and for the period ending July 31, 1997 (the
         "Unaudited Financial Statements," and collectively, with the Audited
         Financial Statements, the "Financial Statements").  The Financial
         Statements fairly present the financial condition and results of
         operations of the Company as of the dates and for the periods
         indicated and have been prepared in conformity with generally accepted
         accounting principles ("GAAP") applied on a consistent basis with
         prior practices.  There were not any significant items of income or
         expense which were unusual or of a nonrecurring nature reflected in
         the Financial Statements.

                 (e)      Except for those liabilities and obligations incurred
         in the ordinary course of business consistent with prior practices
         since the date of the Financial Statements, none of which are
         material, the Financial Statements reflect all liabilities and
         obligations of the Company, accrued, contingent or otherwise (known or
         unknown and asserted or unasserted), arising out of transactions
         effected or events occurring on or prior to the Closing Date.  All
         allowances and reserves shown in the Financial Statements are
         appropriate, reasonable and sufficient to provide for expenses and
         losses thereby contemplated.  The Company is not liable upon or with
         respect to, or obligated in any other way to provide funds in respect
         of or to guarantee or assume in any manner, any debt, obligation or
         dividend of any person, corporation, association, partnership, joint
         venture, trust or other entity.  The Company and each of the Tedco
         Shareholders know of no basis for the assertion of any other claims or
         liabilities of any nature or in any amount.

                 (f)      Except as explicitly disclosed in the July 31, 1997
         balance sheet delivered by the Shareholders to the Purchaser, the
         Company has no liabilities for federal, state or local taxes,
         including but not limited to income, estimated, sales, use, ad
         valorem, personal property, franchise, payroll, employment, social
         security, unemployment, and disability taxes.  The Company has duly
         and timely filed all tax returns required to be filed by or on behalf
         of it pursuant to any applicable federal, state or local law for all
         years and periods for which such tax returns have become due.  All
         such tax returns were correct and complete.  All taxes owed by the
         Company or required to be withheld or collected by the Company and
         paid to a taxing authority have been paid to the





                                       7
<PAGE>   8
         appropriate taxing authority, or if they are not yet required to be
         paid to the appropriate taxing authority, have been set aside in
         accounts for such purpose or have been reserved on the books of
         account of the Company.  The Company has never filed an election to be
         treated as an S corporation in accordance with the provisions of
         Section 1362(a) of the Internal Revenue Code.

The representations, warranties and covenants of the Tedco Shareholders set
forth in this Agreement shall survive execution and delivery of this Agreement
and the Closing.

         5.      Closing.  The closing of the transactions contemplated hereby
(the "Closing") will take place concurrently with the execution of this
Agreement at the offices of the Company (or such other place as may be mutually
agreed upon by the parties hereto).  The day on which the Closing occurs is
herein referred to as the "Closing Date." The effective date of the
consummation of the transactions contemplated hereby shall be July 25, 1997.

         dated the Closing Date and addressed to Purchaser stating that to its
         knowledge that there are no pending audits or investigations involving
         the Company and that it has no reason to believe that the Financial
         Statements do not fairly present the financial condition of the
         Company at and for the periods set forth therein;

                 (e)      the Shareholders shall deliver evidence of receipt of
         all required approvals, consents, licenses and permits to the

<PAGE>   9
                 (i)      the Company and the Shareholders shall execute and
         deliver such other documents as are reasonably requested by Purchaser
         to effectuate the purposes and intent of this Agreement.

         7.      [Intentionally Deleted]

         8.      Confidentiality.  The Shareholders agree to hold in confidence
the terms of this Agreement and, except as required by law, will not make the
same available or known to any third party other than their counsel,
accountants and other agents or representatives acting on their behalf, and
then only to the extent necessary, provided each such person is advised of the
confidential nature of the terms hereof and agrees to hold the same in
confidence.

         9.      Noncompetition and Non-solicitation.

                 (a)      With respect to Tedco and the Tedco Shareholders for
         a period of three years after the Closing, and with respect to Fasano
         for a period until the later of three years after the Closing or one
         year after he ceases to be employed by Purchaser, the Company or any
         of their affiliates (the "Noncompetition Period"), and except for
         services performed on behalf of Purchaser or the Company, the
         Shareholders and the Tedco Shareholders (collectively, the "Restricted
         Persons") agree that neither they nor any of their affiliates will
         directly or indirectly either as an individual, a partner or a joint
         venturer, or in any other capacity, (i) invest (other than investments
         in publicly-owned companies which constitute not more than 1% of the
         voting securities of any such company), or engage in, within the State
         of Nevada or within 100 miles of Chicago, Illinois (x) the business of
         selling, renting, or servicing any wireless communication products or
         (y) any other business that is competitive with that of Purchaser, the
         Company or their affiliates (the items listed under clauses (x) and
         (y) hereto are collectively referred to herein as "Competitive
         Businesses"), or (ii) accept employment with or render services to
         Competitive Businesses that engages in such Competitive Business
         within the State of Nevada or within 100 miles of Chicago, Illinois as
         a director, officer, agent, employee, consultant, or any other
         capacity.  For purposes of this Agreement, a "business that is
         competitive with that of Purchaser, the Company or their affiliates"
         specifically includes persons, firms, sole proprietorships,
         partnerships, companies, corporations or other entities that market
         products and/or perform services within the State of Nevada or within
         100 miles of Chicago, Illinois in direct or indirect competition with
         those marketed and/or performed by Purchaser or its affiliates
         including the Company (with regard to the Restricted Persons other
         than Fasano, a business shall only be considered to be competitive
         with that of Purchaser, the Company or their affiliates if it markets
         products and/or performs services that are in direct or indirect
         competition with those marketed and/or performed as of the Closing
         Date by Purchaser, the Company or their affiliates).  Purchaser
         acknowledges and understands that affiliates of certain of the
         Restricted Persons are in the business of re-selling long distance
         phone services and 800 telephone numbers, and Purchaser agrees that
         such business shall not be considered to be a business that is
         competitive with that of Purchaser, the Company or their affiliates.
         The parties agree that, if such non-competition agreement is
         determined by a court of competent jurisdiction to be unenforceable,
         such agreement should be reformed by the court to the extent necessary
         to be enforceable and to give effect to the intent of this Section 9.

                 (b)      During the Noncompetition Period, the Restricted
         Persons will not, directly or indirectly, (i) except on behalf of the
         Company or Purchaser, solicit for any purpose, any customer or former
         customer of the Company or Purchaser, (ii) solicit for employment by
         himself, itself, or





                                       9
<PAGE>   10
         anyone else, any employee of the Company, Purchaser or their
         affiliates or any person who was an employee of the Company, Purchaser
         or their affiliates within the four-month period immediately preceding
         such solicitation or employment, other than such person whose
         employment was terminated by Purchaser or its affiliates; or (iii)
         induce or attempt to induce, any such employee of the Company,
         Purchaser or their affiliates to terminate such employee's employment.

                 (c)      The parties hereto acknowledge that the provisions of
         this Section 9 are supported by good and valuable consideration and
         Purchaser's agreement to consummate the transactions contemplated
         hereby are conditioned upon its receipt of the protection provided in
         this Section 9.  The parties hereto further acknowledge that the scope
         and duration of the covenants set forth in this Section 9 are in all
         respects reasonable.

                 (d)      The Restricted Persons acknowledge and agree that the
         breach by any of them of the provisions of this Section 9 could not be
         adequately compensated with monetary damages and would irreparably
         injure Purchaser and the Company, and, accordingly, that injunctive
         relief and specific performance shall be appropriate remedies to
         enforce the provisions of this Section against the Restricted Persons,
         and the Restricted Persons waive any claim or defense that there is an
         adequate remedy at law for such breach; provided, however, that
         nothing contained herein shall limit the remedies, legal or equitable,
         otherwise available to Purchaser, and all remedies of Purchaser herein
         are in addition to any remedies available to Purchaser at law or
         otherwise.

                 (e)      The Restricted Persons acknowledge and recognize that
         the enforcement of any of the noncompetition provisions in this
         Agreement by Purchaser will not interfere with the Restricted Persons'
         ability to pursue a proper livelihood.  The Restricted Persons further
         represent that they are capable of pursuing a career that would not
         violate the noncompetition provisions hereof to earn a proper
         livelihood.  The Restricted Persons agree that due to the nature of
         such business, the noncompetition restrictions set forth in this
         Agreement are reasonable as to time and geographic area.  At any time
         during the non-compete period, Purchaser may require the Restricted
         Persons to supply such information as Purchaser deems necessary to
         ascertain whether or not the Restricted Persons have complied with, or
         have violated, the covenants set forth in this Section 9.  Any such
         request for information will be sent to the Restricted Persons by
         certified mail, return receipt requested, addressed to such person's
         last known address.  The Restricted Persons shall furnish the
         requested information to Purchaser within 10 days following the
         receipt of such request.

         10.     Expenses; Transfer Tax.  Purchaser, on the one hand, and the
Shareholders, on the other hand, will bear their own costs and expenses of the
transactions contemplated hereby.  The Company will not bear any costs and
expenses of the transactions contemplated hereby.  The Shareholders shall be
liable for and shall pay any transfer tax, sales tax and other similar taxes
resulting from consummation of the transactions contemplated hereby.

         11.     Further Assurances.  At the Closing and after the Closing,
each party hereto shall take all actions and duly execute and deliver or cause
to be executed and delivered all instruments of sale, conveyance, transfer,
assignment or assumption, and all notices, releases, acquittances and other
documents that may be necessary or advisable to consummate the transactions
contemplated in this Agreement, or more fully to sell, convey, transfer,
assign, and deliver to and vest in Purchaser the Shares sold, conveyed,
transferred, assigned, and delivered by the Company pursuant hereto or intended
so to be.  Purchaser acknowledges that the Shareholders are not guaranteeing
the future profits of the Company.

         12.     Indemnification.  The Shareholders and the Tedco Shareholders
shall, jointly and severally, indemnify and hold Purchaser and its affiliates
and the officers, directors, partners, stockholders, employees and agents of
Purchaser and its affiliates harmless from and against any loss, damage, claim,
demand, cause of action, liability, costs or expense (including without
limitation interest, penalties, and attorneys' fees and disbursements) of any
kind or nature whatsoever asserted against or incurred by Purchaser or the
Company by reason of, resulting from, or based upon: (a) any misrepresentation,
breach of warranty or breach or nonfulfillment of any covenant or other
agreement made by them herein or in any other agreement executed and delivered
by them pursuant to this Agreement, (b) any liability of the Company for
failure to file any federal, state or local income tax return, and any
liability or obligation to pay any federal, state or local taxes, relating to
any tax period ending on or prior to the Closing Date and any liability to pay
interest or penalties upon or with respect to any of the foregoing, (c) any
obligation or liability relating to any period prior to the Closing Date
relating to any employee benefit plan of the Company or relating to any
employee of the Company who is not retained by Purchaser or the Company after
the Closing, and (d) any obligation or liability for any finders', brokers' or
agents' fee in connection with the transactions contemplated hereby; provided,
however, the liability of each Shareholder pursuant to the provisions of this
Section 12 shall not exceed the Purchase Price received by him or it.  No claim
shall be made against the Shareholders pursuant to this Section 12 unless and
until the aggregate amount of such claims exceed the sum of $12,500, whereupon
the indemnified party shall be entitled to recover the full amount of all
claims, including the initial $12,500.

NO INVESTIGATION BY OR ON BEHALF OF, AND NO NEGLIGENCE OF, PURCHASER OR ITS
AFFILIATES, NOR ANY INFORMATION THAT THEY MAY HAVE OR OBTAIN WILL AFFECT THE
INDEMNIFICATION OBLIGATIONS OF THE SHAREHOLDERS OR THE TEDCO SHAREHOLDERS
HEREUNDER.

         13.     Entire Agreement: Counterparts.  This Agreement constitutes
the entire agreement among the parties pertaining to the subject matter hereof
and supersedes all other prior or contemporaneous agreements and
understandings, both oral and written, of the parties in connection therewith.
This Agreement may be executed in counterparts.

         14.     Severability.  The parties hereto intend all provisions of
this Agreement including the provisions set forth in Section 9 hereof to be
enforced to the fullest extent permitted by law.  Accordingly, should a court
of competent jurisdiction determine that the scope of any provision herein is
too broad to be enforced as written, the parties intend that the court reform
the provision to such narrower scope as it determines to be reasonable and
enforceable.  In addition, however, the Restricted Persons agree that the
noncompetition agreements and nonemployment agreements set forth above each
constitute separate agreements independently supported by good and adequate
consideration and shall be severable from the other provisions of, and shall
survive, this Agreement.  If any provision of this Agreement is held to be
illegal, invalid or unenforceable under present or future laws effective during
the term hereof, such provision shall be fully severable and this Agreement
shall be construed and enforced as if such illegal, invalid or unenforceable
provision never comprised a part of this Agreement; and the remaining
provisions of this Agreement shall remain in full force and effect and shall
not be affected by the illegal, invalid or unenforceable provision or by its
severance herefrom.  Furthermore, in lieu of such illegal, invalid or
unenforceable provision, there shall be added automatically as part of this
Agreement, a provision as similar in its terms to such illegal, invalid or
unenforceable provision as may be possible and be legal, valid and enforceable.

a written instrument signed by all the parties hereto.

construed in accordance with the laws of the State of Texas, without regard to
the conflicts of laws principles thereof.  Venue for any disputes regarding
this Agreement, the transactions contemplated hereby or the liabilities or
obligations imposed hereunder shall be in federal or state court in Dallas

         Re:     Tomba Communications, L.L.C.

Gentlemen:

         The purpose of this letter agreement (this "Agreement") is to set
forth the terms and conditions agreed to by and among BearCom Operating, L.P.,
a Texas limited partnership ("Purchaser"), Tomba Communications, L.L.C., a
Louisiana limited liability company (the "Company"), Joseph J. Tomba and Thomas
C. Tomba (Joseph J. Tomba and Thomas C. Tomba are sometimes collectively
referred to herein as the "Sellers") for Purchaser's purchase of certain assets
of the Company.  For good and valuable consideration, the receipt and adequacy
of which are hereby acknowledged, the parties hereto hereby agree as follows:

         1.      Sale of Assets; Purchase Price.

                 (a)      Subject to the terms and conditions hereinafter set
         forth, at the Closing (hereinafter defined), Purchaser will purchase
         and the Company will sell, convey and assign, free and clear of all
         liens, claims and encumbrances, all of the assets owned by the Company
         as of the Closing Date (hereinafter defined) other than cash,
         including, but not limited to, all of the real property, fixed assets,
         inventory, rental two- way radios, accounts receivable, accrued coop
         receivables, intangible assets, customer data and related information,
         permits, computers, the contracts set forth on Exhibit A hereto (the
         "Assumed Contracts"), records, leasehold improvements, fixtures, and
         the phone and fax numbers of the Company (collectively, the "Assets").

                 (b)      The purchase price for the Assets (the "Purchase
         Price") shall be [Confidential Treatment Requested with SEC] and 
         shall be payable by delivery at the Closing of Purchaser checks or 
         wire transfers of the Purchase Price.

                 (c)      Taxes for the current year relating to any of the
         Assets (including the Real Property (hereinafter defined)) shall be
         prorated through the Closing Date.  An estimated adjustment shall be
         made at the Closing.  Once actual amounts are known (including when
         the taxes are actually assessed on the Real Property), the Company and
         the Sellers, on the one hand, and/or the Purchaser shall pay the other
         any amounts due to correctly reflect the intent of parties reflected
         in the proration provisions set forth herein.

<PAGE>   2
         2.      Liabilities Not Assumed.

                 (a)      Purchaser will not assume or be liable for any
         liabilities or obligations of the Company other than the liabilities
         described on Exhibit B hereto (the "Assumed Liabilities"), and the
         Company and the Sellers will, jointly and severally, indemnify
         Purchaser against and hold it harmless from all such liabilities and
         obligations other than the Assumed Liabilities.

                 (b)      The liabilities and obligations of the Company that
         Purchaser will not assume include, but are not limited to, all
         liabilities or obligations that relate to the period, or conditions
         existing, before the Closing, including any liabilities of the Company
         to either Seller or any other person or entity controlled by,
         controlling or under common control with any of them, trade payables
         and other accounts payable not set forth on Exhibit B hereto incurred
         in the ordinary course of business not to exceed $140,000, bank debt
         or other debts for borrowed money, pension, and other employee benefit
         plan liabilities (including any accruals relating thereto), breaches
         or violations of agreements to which the Company or the Assets are
         subject, violations of law or applicable statutory regulations,
         property damage, personal injury, negligence, sexual abuse or
         harassment or employee claims based on events occurring prior to the
         Closing Date, any obligations of the Company to pay employees for
         accrued but not taken vacations, liabilities or obligations to
         remediate or cleanup any contamination or pollution of the air, soil
         or other environmental conditions occurring or existing prior to the
         Closing Date, or any contingent liabilities (whether or not known).

         3.      Representations and Warranties.  The Company and the Sellers
jointly and severally represent and warrant to Purchaser that the following are
true and correct as of the date hereof in all material respects except as set
forth in the Schedules hereto and that the following will be true and correct
as of the Closing Date:

                 (a)      The Company is a limited liability company duly
         organized, validly existing and in good standing under the laws of the
         State of Louisiana with all requisite power and authority to carry on
         the business in which it is now engaged, to own and lease the
         properties it now owns and leases, and to execute and deliver this
         Agreement and perform its obligations hereunder.  The Company is
         qualified to do business as a foreign limited liability company in the
         State of Texas.  The Company is not required to be qualified to
         conduct business in any jurisdiction other than the States of
         Louisiana and Texas.  The Company does not have any subsidiaries or
         any equity or other ownership interest in any corporation, partnership
         or other entity.

                 (b)      The Sellers are the sole record and beneficial owners
         of all of the outstanding interests of the Company.

                 (c)      Set forth on Schedule 3(c) is a true and correct list
         of assets used by the Company  including fixed assets, inventory and
         rental two-way radios.  The Company holds good and indefeasible title
         to all of such assets, free and clear of all liens, claims and
         encumbrances other than the liens described on Schedule 3(c).  The
         Assets purchased by Purchaser at the  Closing will include all of the
         assets listed on Schedule 3(c) (other than inventory sold in the
         ordinary course of business since the date of that Schedule on a basis
         consistent with prior practices) plus inventory purchased
<PAGE>   3
         since the date of that Schedule (which will have a value of at least
         as much as the inventory sold by the Company between the date of that
         Schedule and Closing).  At the Closing, Purchaser will acquire all of
         the assets, property and goodwill of every kind and character used by
         the Company, free and clear of all liens, claims and encumbrances.
         The Assets are all of the assets which are necessary for Purchaser to
         operate the business of the Company in the manner the Company has been
         operating it.

                 (d)      The Company has the power and authority to transfer
         the Assets without the consent of any other person.  The Sellers have
         the sole right to vote or direct the voting of the interests in the
         Company, at their discretion, on any matter submitted to a vote of
         members of the Company.

                 (e)      The Company owns all of the assets reflected in the
         August 31, 1997 balance sheet of the Company previously delivered by
         the Company to Purchaser, along with property acquired by the Company
         since August 31, 1997.  The inventory amounts on the August 31, 1997
         balance sheets reflect the cost of such inventory.  The assets owned
         and leased by the Company constitute all of the assets, property and
         goodwill of every kind and character used in the business of the
         Company.  The Company has an owners' title insurance policy with
         respect to each tract of real property owned by it ("Real Property")
         and has provided true and correct copies thereof to Purchaser.

                 (f)      The Sellers have furnished to Purchaser the compiled
         balance sheet and related statements of income and cash flows of the
         Company at and for the year ending December 31, 1996 and the
         internally-generated balance sheet and related statements of income of
         the Company at and for the period ending August 31, 1997
         (collectively, "Financial Statements").  To the best knowledge of the
         Company and the Sellers, the Financial Statements fairly present the
         financial condition and results of operations of the Company as of the
         dates and for the periods indicated and, to the best knowledge of the
         Company and the Sellers, have been prepared in conformity with
         generally accepted accounting principles ("GAAP") applied on a
         consistent basis with prior practices.  To the best knowledge of the
         Company and the Sellers, there were not any significant items of
         revenue or expense which were unusual or of a nonrecurring nature
         reflected in the Financial Statements.  To the best knowledge of the
         Company and the Sellers, except for those liabilities and obligations
         incurred in the ordinary course of business consistent with prior
         practices since the date of the Financial Statements, none of which
         are material, the Financial Statements reflect all liabilities and
         obligations of the Company, accrued, contingent or otherwise (known or
         unknown and asserted or unasserted), arising out of transactions
         effected or events occurring on or prior to the Closing Date.  To the
         best knowledge of the Company and the Sellers, all allowances and
         reserves shown in the Financial Statements are appropriate, reasonable
         and sufficient to provide for expenses and losses thereby contemplated
         including the reserve for all taxes payable.

                 (g)      This Agreement has been duly authorized, executed and
         delivered by the Company and each Seller and is a valid and binding
         agreement of each of them, enforceable against each of them in
         accordance with its terms.

                 (h)      Neither the execution and delivery of this Agreement
         nor the consummation of the transactions contemplated herein violates,
         breaches, conflicts with or constitutes a default under, or permits
         the termination or the acceleration of maturity of, or results in the
         imposition of any lien, claim or encumbrance upon any property or
         asset of the Company pursuant to, the organizational





                                       3
<PAGE>   4
         documents of the Company or any law, agreement, mortgage or other
         instrument or provision of law to which or under which any of the
         Company or either Seller is a party or bound.

                 (i)      Except for the consents set forth on Schedule 3(i)
         hereto, no consents or approvals are required for execution of this
         Agreement by the Company or either Seller or their consummation of the
         transactions contemplated herein.

                 (j)      The Company and its business are, and have been, in
         compliance with all applicable laws, rules, regulations, ordinances,
         licenses, permits and orders.  The only plans of the Company subject
         to the Employee Retirement Income Security Act of 1974, as amended,
         are its 401(k) Plan and its health insurance plan.

                          The Company purchased the Real Property on December
         28, 1995.  The Company has provided Purchaser with a true and correct
         copy of an environmental audit report relating to the Real Property.
         To the best knowledge of the Company and the Sellers, the location,
         construction, occupancy, operation and use of all of the Real
         Property, including the buildings, improvements, fixtures and
         equipment forming a part thereof, do not violate, and the Company has
         complied with, any applicable federal, state and local law, rule,
         ordinance, regulation, judgment, order determination of any
         governmental authority or any board of fire underwriters (or other
         body exercising similar functions), or any restrictive covenant or
         deed restriction (recorded or otherwise) affecting the Real Property,
         including without limitation all applicable zoning ordinances and
         building codes and laws, common laws, ordinances, regulations or
         policies, as well as orders, decrees, judgments or injunctions issued,
         promulgated, approved or entered thereunder relating to the
         environment, health and safety and the use, handling, transportation,
         production, disposal, discharge or storage of "hazardous substances"
         (including, without limitation, any pollutant, toxic substance,
         hazardous waste, compound, element or chemical that is defined as
         hazardous, toxic, noxious or dangerous pursuant to such Applicable
         Environmental Laws (as defined herein) or regulated in any manner
         pursuant thereto) or to industrial hygiene or the environmental
         conditions on, under or about the Real Property, including, without
         limitation, soil, groundwater, and indoor and ambient air conditions
         (collectively, "Applicable Environmental Laws").

                          Without limiting the generality of the foregoing
         subsection, to the best knowledge of the Company and the Sellers no
         claim has been asserted, and there are no unasserted claims (whether
         or not the potential claimant may be aware of the claim) that might be
         asserted against the Company or Purchaser, and there is no basis for
         any claims, arising out of the handling, treatment, storage,
         transportation, disposal (or the arranging therefor) or the discharge
         into the environment of any hazardous or toxic substance, or hazardous
         or solid waste, including any constituent thereof or other pollutant
         or contaminant or the exposure of workers in the workplace to any
         hazardous or toxic substance or contaminant, including, without
         limitation, claims for penalties, natural resource damage, personal
         injury, property damage or response or remedial costs, whether at
         common law or under any law relating to such substance, including,
         without limitation, the Comprehensive Environmental Response,
         Compensation and Liability Act and the Superfund Amendments and
         Reauthorization Act, the Resource Conservation and Recovery Act, the
         Federal Water Pollution Control Act, the Toxic Substance Control Act,
         the Occupational Safety and Health Act ("OSHA") and applicable state
         and local laws.  To the best knowledge of the Company and the Sellers,
         none of Sellers nor the Company have obtained or are required to
         obtain, and none of Sellers nor the Company knows of any reason
         Purchaser will be required to obtain, any permits, licenses or similar





                                       4
<PAGE>   5
         authorizations to construct, occupy, operate or use any buildings,
         improvements, fixtures or equipment forming a part of the Real
         Property by reason of any Applicable Environmental Laws.

                          To the best knowledge of the Company and the Sellers,
         no underground storage tanks for petroleum or any other substance, or
         underground piping or conduits associated with such tanks, are or have
         previously been located on the Real Property.  To the best knowledge
         of the Company and the Sellers, no asbestos-containing materials or
         PCB-containing materials were installed or are present on the Real
         Property.  To the best knowledge of the Company and the Sellers, none
         of Sellers nor the Company has ever been refused insurance coverage,
         nor has insurance coverage ever been cancelled, as a result of the
         presence of pollutants or contaminants, including, but not limited to,
         hazardous waste, solid waste or hazardous substances, on the Real
         Property.  To the best knowledge of the Company and the Sellers, there
         are no activities on the Real Property, including but not limited to
         the disposal of industrial waste, that would currently require deed
         recordation by the Company now or at any future date.  To the best
         knowledge of the Company and the Sellers, there are no active or
         inactive solid waste management units or hazardous waste management
         units on the Real Property.  To the best knowledge of the Company and
         the Sellers, there has been no past or present spill, discharge or
         other release of hydrocarbons or hazardous or toxic substances onto or
         from the Real Property.  To the best knowledge of the Company and the
         Sellers, Sellers and the Company have taken all steps necessary to
         determine and have determined that no hazardous or toxic substances,
         hazardous or solid wastes are present or have at any time been
         disposed of or otherwise released on or to the Real Property.  To the
         best knowledge of the Company and the Sellers, no building materials
         used to construct improvements upon the Real Property contain any
         toxic or hazardous substances, or hazardous or solid wastes,
         including, but not limited to, asbestos, PCBs, formaldehyde, chlordane
         or heptachlor.  To the best knowledge of the Company and the Sellers,
         there are no company plans or documents, whether or not government
         approved, including, but not limited to, contingency plans, closure
         and post-closure plans which impose environmental obligations on
         Sellers or the Company or against the Real Property.  To the best
         knowledge of the Company and the Sellers, there are no requirements,
         whether by regulation, agreement or otherwise, imposing financial
         obligations with respect to environmental conditions or activities.
         To the best knowledge of the Company and the Sellers, there are no
         environmental liens or security interests against the Real Property
         nor are there any environmental liens or actions pending which would
         result in the creation of any lien relating to environmental
         conditions of the Real Property.

                          To the best knowledge of the Company and the Sellers,
         Sellers and the Company have provided Purchaser with all environmental
         studies and reports in their possession or control conducted by
         independent contractors, environmental records of Sellers or the
         Company, and correspondence with any governmental entities concerning
         environmental conditions of the Real Property, or which identify
         underground tanks, or otherwise relate to contamination of the soil or
         groundwater.

                 (k)      The Company has provided Purchaser with access to,
         and will at Closing provide originals of, true, correct, and current
         copies of the Assumed Contracts.  To the best knowledge of the Company
         and the Sellers, all of the Assumed Contracts are in full force and
         effect.  To the best knowledge of the Company and the Sellers, neither
         party to any Assumed Contract is in default under any of such Assumed
         Contract, and no event has occurred that would, with the passage of
         time, cause a default under any of such Assumed Contracts.  To the
         best knowledge of the Company





                                       5
<PAGE>   6
         and the Sellers, the Company has paid the other party to each such
         Assumed Contract all amounts it owes them.  The Company is not subject
         to any non-competition or other agreement that would restrict its
         ability to engage in any business.

                 (l)      The Company has provided to Purchaser access to, and
         will at Closing provide originals of, true and correct copies of all
         of the personnel records of the Company.  To the best knowledge of the
         Company and Sellers, the Company has not granted or become obligated
         to grant any increases in the wages or salary of, or paid or become
         obligated to pay any bonus or made or become obligated to make any
         similar payment to or grant any benefit to or on behalf of, any
         officer, employee or agent.  To the best knowledge of the Company and
         Sellers, the Company does not have any direct or indirect, express or
         implied, obligation to pay severance or termination pay to any officer
         or employee of the Company or to pay any amounts to any consultant,
         agent or similar person or entity.  None of the Company or either
         Seller has any knowledge of any facts which would indicate that any
         employee of the Company would not accept an offer of employment from
         Purchaser if such offer is tendered on a basis no less favorable than
         that upon which such employee is currently employed by the Company.
         The Company is not a party to any collective bargaining agreement or
         the subject of any union organization effort, and there are not any
         pending or threatened strikes, labor disputes, slow downs or stoppages
         pending or threatened against the Company.

                 (m)      To the best knowledge of the Company and the Sellers,
         (i) all of the fixed assets (including but not limited to all
         equipment), owned or leased by the Company are in condition to
         sufficiently operate the business, and are fit for their intended use
         in the ordinary course of business, and conform in all respects with
         all applicable ordinances, regulations and other laws and there are no
         known latent defects therein, (ii) all regular maintenance or service
         requirements, and product recalls, have been followed, installed, or
         otherwise implemented on and with respect to the Assets, (iii) all
         inventory of the Company is in good, standard, and merchantable
         condition and is not defective, and (iv) the inventory of the Company
         is properly recorded on the Financial Statements at cost (last
         in-first out) in accordance with GAAP.

                 (n)      To the best knowledge of the Company and Sellers, set
         forth in Schedule 3(n) hereto is a complete and accurate list and
         descriptions of all accounts receivable of the Company's business from
         sales made as of September 30, 1997, and the payments and rights to
         receive payments related thereto.  The Company has good and
         indefeasible title to the accounts receivable it is selling to
         Purchaser, free and clear of any security interests, liens,
         encumbrances, or other charges; to the best knowledge of the Company
         and the Sellers, none of such accounts receivable are subject to any
         offsets or claims of offsets; and to the best knowledge of the Company
         and the Sellers, none of the obligors of the accounts receivable have
         given notice that they will or may refuse to pay the full amount
         thereof or any portion thereof.

                 (o)      None of the Company or either Seller knows or has any
         reason to believe, or has received notice or information, that any
         major supplier or major customer of the Company or any other party
         that does business with the Company will cease or refuse to do
         business with Purchaser after the consummation of the transactions
         contemplated hereby in the same manner, and same amount, as previously
         conducted with the Company.  None of the Company or either Seller has
         received any notice of any disruption (including delayed deliveries or
         allocations by suppliers or service providers) in the availability of
         the products used by the Company, nor are any of Company





                                       6
<PAGE>   7
         or either Seller aware of any facts which could lead the Company to
         believe that Purchaser will be subject to any such material
         disruption.  None of the Company or either Seller is aware of any
         condition (financial or otherwise) affecting any major supplier or any
         other party that does business with the Company that will, or could be
         reasonably expected to, now or in the future, reduce each such party's
         ability to do business with Purchaser in substantially the same manner
         and amount that each such party has done business with the Company
         during the period preceding this Agreement.  Set forth in Schedule
         3(o) are complete and accurate lists of the customers that constituted
         5% or more of the revenues of the Company for the twelve-month period
         ended August 31, 1997.

                 (p)      To the best knowledge of the Company and Sellers, all
         information furnished to Purchaser by any of Company or either Seller,
         whether or not herein or in any Exhibit or Schedule hereto, is true,
         correct, and complete.  To the best knowledge of the Company and
         Sellers, such information states all material facts required to be
         stated therein or necessary to make the statements therein, in light
         of the circumstances under which such statements are made, true,
         correct and complete in all material respects.  The Company and the
         Sellers have made due inquiry and investigation concerning the matters
         to which representations and warranties made by them under this
         Agreement pertain and the Company and the Sellers are unaware of any
         facts, events or circumstances which have not been disclosed to
         Purchaser which are material to the financial condition, results of
         operations, business or prospects of Company.

The representations, warranties and covenants of the Company and the Sellers
set forth in this Agreement shall survive execution and delivery of this
Agreement and the Closing.

         4.      Closing.  The closing of the transactions contemplated hereby
(the "Closing") will take place at 10:00 a.m., local time, on October 15, 1997
at the offices of the Company (or such other date, time and/or place as may be
mutually agreed upon by the parties hereto).  The day on which the Closing
occurs is herein referred to as the "Closing Date."

         At the Closing, (a) the Company shall deliver to Purchaser a General
Warranty Deed and Bill of Sale in forms satisfactory to Purchaser and such
other documents and instruments as Purchaser shall reasonably request
sufficient to vest title to such Assets in Purchaser, free and clear of all
liens, claims and encumbrances, (b) the Company and Purchaser will execute and
deliver an Assignment and Assumption Agreement pursuant to which the Company
would assign all of its right, title and interest in the Assumed Contracts to
Purchaser, and Purchaser would assume the Assumed Liabilities and all
liabilities under the Assumed Contracts that arise after the Closing Date (and
the Purchaser would agree to indemnify the Company and hold it harmless from
such Assumed Liabilities and such liabilities under the Assumed Contracts), and
(c) the Company shall provide Purchaser with an owner's title insurance policy
with respect to the Real Property (the cost of which shall be split between the
Company and Purchaser) and such other items reasonably requested by Purchaser
relating to the transfer of the Real Property.

         5.      Covenants.

                 (a)      The Company and the Sellers, jointly and severally,
         covenant and agree that from the date hereof until the Closing, except
         as otherwise permitted or contemplated by this Agreement or with the
         written consent of Purchaser, the Company shall not take any other
         action that would cause or permit the representations and warranties
         of the Company and the Sellers made in this Agreement to be inaccurate
         at the time or Closing or preclude any of the Company and the Sellers
         from making such representations and warranties at and as of the time
         of the Closing.





                                       7
<PAGE>   8

                 (b)      At or promptly after the Closing, the Company shall
         notify (in form satisfactory to Purchaser) all of the obligors of
         accounts receivable that are payable to the Company that such obligors
         should pay such receivables to Purchaser at the address specified by
         Purchaser.  If, nonetheless, the Company receives payments for any
         such receivables, it will promptly endorse the checks to the order of
         Purchaser and promptly deliver such checks to Purchaser.  If, however,
         the Company so receives payment for a receivable at a time in which
         the Purchaser is delinquent in paying a payable that it has assumed
         from the Company and is required to pay (and does not have a valid
         defense or other valid reason not to pay), the Company, upon 14 days'
         written notice to Purchaser, shall have the right to cash such check
         and pay such payable (and to the extent there is money remaining after
         payment of such payable, the Company shall deliver such funds to
         Purchaser).

                 (c)      The Purchaser shall cooperate with the Company's
         efforts in seeking to have the Company and Sellers released from
         liability on the Assumed Liabilities, and the Purchaser agrees to
         provide such information to the payees of such payables as such payees
         shall reasonably request in connection with releasing the Company and
         Sellers from such liability.

         6.      Conditions Precedent to Obligations of Purchaser.  The
obligations of Purchaser to consummate the transactions contemplated by this
Agreement shall be subject to the satisfaction on or before the Closing Date of
each of the following conditions:

                 (a)      The Company and the Sellers shall have executed and
         delivered to Purchaser each document and instrument (including the
         title insurance policy) required to be executed and delivered by any
         of them pursuant to this Agreement, and shall have, or shall have
         caused to be, satisfied or complied with and performed in all respects
         all terms, covenants and conditions of this Agreement to be complied
         with or performed by any of them on or before the Closing Date.

                 (b)      All of the representations and warranties made by the
         Company and the Sellers in this Agreement shall be true and correct in
         all respects as of the date thereof and at the Closing Date with the
         same force and effect as if such representations and warranties had
         been made at and as of, the Closing Date.

                 (c)      Purchaser shall have completed its due diligence
         investigation of the Company, its businesses and operations, and be
         satisfied, in its sole discretion, with the results thereof.

                 (d)      Counsel to the Company and the Sellers shall have
         delivered to Purchaser a legal opinion dated the Closing Date in form
         reasonably acceptable to Purchaser opining to the matters set forth in
         Exhibit C hereto.

                 (e)      The Company's accounting firm shall have delivered a
         letter dated the Closing Date and addressed to Purchaser stating that
         to its knowledge that there are no pending audits or investigations
         involving the Company and that it has no reason to believe that the
         Financial Statements at and for the year ending December 31, 1996 do
         not fairly present the financial condition and operating results of
         the Company at and for the periods set forth therein.

<PAGE>   9
                 (f)      The Company and the Sellers shall have delivered
         evidence of receipt of all required approvals, consents, licenses and
         permits to the transactions contemplated herein in a form acceptable
         to the Purchaser in its sole discretion.

                 (g)      The Company and the Sellers shall have delivered
         estoppel letters from such persons as Purchaser shall request in a
         form acceptable to Purchaser in its sole discretion.

                 (h)      All amounts due pursuant to the loan agreement
         described on Schedule 6(h) hereto shall be paid in full, all liens
         securing such amounts shall be released, and evidence satisfactory to
         Purchaser of the same shall be delivered to Purchaser.

                 (i)      The Company and the Sellers shall have executed and
         delivered such other documents as are reasonably requested by
         Purchaser to effectuate the purposes and intent of this Agreement.

         If Purchaser's conditions are not satisfied by October 31, 1997,
Purchaser shall have the right to terminate this Agreement and any obligations
it has hereunder.  If Purchaser's conditions are not satisfied by October 31,
1997 through no fault of the Company, the Company shall have the right to
terminate this Agreement and any obligations it has hereunder.

         7.      Purchase Price Allocation.  The parties hereto hereby agree
that, for all accounting and foreign, federal, state and local tax reporting
purposes, the Purchase Price shall be allocated in accordance with the relative
fair market values of the Assets and the covenants set forth in Section 9
hereof, as determined by Purchaser, as soon as practicable after the Closing
Date.  Purchaser shall provide to the Company and the Sellers a schedule
setting forth such allocation as soon as practicable after the Closing Date,
and shall thereafter notify the Company and the Sellers of any changes thereto.
Each of the parties hereto hereby covenants and agrees that it will not take a
position on any tax return, before any governmental agency charged with the
collection of any tax, or in any judicial proceeding that is in any way
inconsistent with the terms of this Section 7.

         8.      Confidentiality.  The Company and the Sellers agree to hold in
confidence the terms of this Agreement and, except as required by law, will not
make the same available or known to any third party other than their counsel,
accountants and other agents or representatives acting on their behalf, and
then only to the extent necessary, provided each such person is advised of the
confidential nature of the terms hereof and agrees to hold the same in
confidence.

         9.      Noncompetition and Non-solicitation.

                 (a)      Until three years after the Closing (the
         "Noncompetition Period"), the Company and the Sellers agree that none
         of them nor any of their affiliates will directly or indirectly either
         as an individual, a partner or a joint venturer, or in any other
         capacity, (i) invest (other than investments in publicly-owned
         companies which constitute not more than 1% of the voting securities
         of any such company), or engage in, within any place in the State of
         Texas that is within 100 miles of Houston, Texas (the "Noncompetition
         Area") (x) the business of selling, renting, or servicing any wireless
         communication products or (y) any other business that is competitive
         with that of Purchaser or its affiliates (the items listed under
         clauses (x) and (y) hereto are collectively referred to herein as
         "Competitive Businesses"), or (ii) accept employment with or render
         services to Competitive





                                       9
<PAGE>   10
         Businesses that engage in such Competitive Business within the
         Noncompetition Area as a director, officer, agent, employee,
         consultant, or any other capacity.  For purposes of this Agreement, a
         "business that is competitive with that of Purchaser or its
         affiliates" specifically includes persons, firms, sole
         proprietorships, partnerships, companies, corporations or other
         entities that market products and/or perform services in direct or
         indirect competition with those marketed and/or performed by Purchaser
         or its affiliates within the Noncompetition Area.  The parties agree
         that, if such non-competition agreement is determined by a court of
         competent jurisdiction to be unenforceable, such agreement should be
         reformed by the court to the extent necessary to be enforceable and to
         give effect to the intent of this Section 9.

                 (b)      Sellers have advised Purchaser that it has certain
         customers through its Louisiana affiliate that, since on or prior to
         January 1, 1996, have purchased two-way radios for offices of such
         customers that may be in the Noncompetition Area .  Schedule 9(b)
         hereto sets forth such customers (sales to such customers are not
         included in the Financial Statements of the Company).  Purchaser
         agrees that if Sellers sell two-way radios to its customers in
         Louisiana that are set forth on Schedule 9(b) hereto, and such
         customers provide such two-way radios to their offices located in the
         Noncompetition Area, such sales shall not be considered to violate the
         provisions set forth in this Section 9.

                 (c)      During the Noncompetition Period, none of the Company
         or either Seller will, directly or indirectly, (i) solicit for any
         purpose, any customer or former customer of the Company, (ii) solicit
         for employment by himself, itself, or anyone else, any employee of the
         Company that Purchaser desires to hire after the Closing, Purchaser or
         their affiliates or any person who was an employee of Purchaser or
         their affiliates within the six-month period immediately preceding
         such solicitation or employment, other than such person whose
         employment was terminated by Purchaser or its affiliates and other
         than Lael Lockhart if Lael Lockhart approaches the Sellers about a
         position in Louisiana; or (iii) induce or attempt to induce, any such
         employee of Purchaser or their affiliates to terminate such employee's
         employment.

                 (d)      The parties hereto acknowledge that the provisions of
         this Section 9 are supported by good and valuable consideration and
         Purchaser's agreement to consummate the transactions contemplated
         hereby are conditioned upon its receipt of the protection provided in
         this Section 9.  The parties hereto further acknowledge that the scope
         and duration of the covenants set forth in this Section 9 are in all
         respects reasonable.

                 (e)      The Company and the Sellers acknowledge and recognize
         that the enforcement of any of the noncompetition provisions in this
         Agreement by Purchaser will not interfere with the ability of any of
         them to pursue a proper livelihood.  Each of the Sellers further
         represents that he is capable of pursuing a career that would not
         violate the noncompetition provisions hereof to earn a proper
         livelihood.  The Company and the Sellers agree that due to the nature
         of such business, the noncompetition restrictions set forth in this
         Agreement are reasonable as to time and geographic area.  At any time
         during the non-compete period, if the Company reasonably suspects that
         the Company or a Seller has violated one or more provisions of this
         Section 9, Purchaser may require the Company and/or the Sellers to
         supply such information as Purchaser may reasonably request to
         ascertain whether or not the Company and/or the Sellers has complied
         with, or have violated, the covenants set forth in this Section 9.
         Any such request for information will be sent to the Company and/or
         the Sellers by certified mail, return receipt requested, addressed to
         such person's last known





                                       10
<PAGE>   11
         address.  The Company and/or the Sellers shall furnish the requested
         information to Purchaser within 10 days following the receipt of such
         request.

         10.     Expenses.  Purchaser, on the one hand, and the Company and the
Sellers, on the other hand, will bear their own costs and expenses of the
transactions contemplated hereby.

         11.     Further Assurances.  At the Closing and after the Closing,
each party hereto shall take all actions and duly execute and deliver or cause
to be executed and delivered all instruments of sale, conveyance, transfer,
assignment or assumption, and all notices, releases, acquittances and other
documents that may be necessary or advisable to consummate the transactions
contemplated in this Agreement, or more fully to sell, convey, transfer,
assign, and deliver to and vest in Purchaser the Assets sold, conveyed,
transferred, assigned, and delivered pursuant hereto or intended so to be.

         12.     Indemnification.  Each of the Company and the Sellers shall,
jointly and severally, indemnify and hold Purchaser and its affiliates and the
officers, directors, partners, stockholders, employees and agents of Purchaser
and its affiliates harmless from and against any loss, damage, claim, demand,
cause of action, liability, costs or expense (including without limitation
interest, penalties, and attorneys' fees and disbursements) of any kind or
nature whatsoever asserted against or incurred by Purchaser by reason of,
resulting from, or based upon: (a) any misrepresentation, breach of warranty or
breach or nonfulfillment of any covenant or other agreement made by any of them
herein or in any other agreement executed and delivered by any of them pursuant
to this Agreement, (b) any liability of the Company for failure to file any
federal, state or local income tax return, and any liability or obligation to
pay any federal, state or local taxes, relating to any tax period ending on or
prior to the Closing Date and any liability to pay interest or penalties upon
or with respect to any of the foregoing, (c) any obligation or liability
relating to any period prior to the Closing Date (i) relating to any employee
benefit plan of the Company or (ii) relating to any employee of the Company who
is not retained by the Company or hired by Purchaser after the Closing, (d) any
product liability or breach of warranty claims relating to products sold by the
Company, and all tort or general liability claims arising or relating to
occurrences from any nature relating to the business of the Company, before the
Closing, whether any or such claims or asserted before or after the Closing,
(e) operations of the Company prior to the Closing or conditions in existence
prior to the Closing that give rise to liability (other than Assumed
Liabilities) including, but not limited to, liabilities under any Applicable
Environmental Laws, and (f) any obligation or liability for any finders',
brokers' or agents' fee in connection with the transactions contemplated
hereby.  Any claim for indemnification pursuant to any of clauses (a), (b),
(c), (d) or (f) of this Section 12 must be asserted against the Company or the
Sellers pursuant to a lawsuit filed on or before the date that is two years
after the Closing (such filing shall be sufficient to preserve Purchaser's
indemnification rights even if the amount of damages is not known until after
such date).

         13.     Use of Tomba Name.  Purchaser shall be permitted to use the
Tomba and Tomba Communications names in connection with the Assets purchased by
Purchaser for a period of 120 days after the Closing.

         14.     Entire Agreement; Counterparts.  This Agreement constitutes
the entire agreement among the parties pertaining to the subject matter hereof
and supersedes all other prior or contemporaneous agreements and
understandings, both oral and written, of the parties in connection therewith.
This Agreement may be executed in counterparts.

         15.     Severability.  The parties hereto intend all provisions of
this Agreement including the provisions set forth in Section 9 hereof to be
enforced to the fullest extent permitted by law.  Accordingly, should a court
of competent jurisdiction determine that the scope of any provision herein is
too broad to be enforced as written, the parties intend that the court reform
the provision to such narrower scope as it determines to be reasonable and
enforceable.  In addition, however, the Company and the Sellers agree that the
noncompetition agreements, nonemployment agreements and nonsolicitation
agreements set forth above each constitute separate agreements independently
supported by good and adequate consideration and shall be severable from the
other provisions of, and shall survive, this Agreement.  If any provision of
this Agreement is held to be illegal, invalid or unenforceable under present or
future laws effective during the term hereof, such provision shall be fully
severable and this Agreement shall be construed and enforced as if such
illegal, invalid or unenforceable provision never comprised a part of this
Agreement; and the remaining provisions of this Agreement shall remain in full
force and effect and shall not be affected by the illegal, invalid or
unenforceable provision or by its severance herefrom.  Furthermore, in lieu of
such illegal, invalid or unenforceable provision, there shall be added
automatically as part of this Agreement, a provision as similar in its terms to
such illegal, invalid or unenforceable provision as may be possible and be
legal, valid and enforceable.

         16.     Amendments.  This Agreement may be amended or modified only by
a written instrument signed by all the parties hereto.

         17.     Governing Law; Venue.  This Agreement shall be governed and
construed in accordance with the laws of the State of Texas, without regard to
the conflicts of laws principles thereof.  Venue for any disputes regarding
this Agreement, the transactions contemplated hereby or the liabilities or
obligations imposed hereunder shall be in federal or state court in Harris
County, Texas.

         18.     Notices.  Any notices, consents, demands, requests, approvals
and other communications to be given under this Agreement by any party to
another shall be deemed to have been duly given if given in writing and
personally delivered or sent by mail, registered or certified, postage prepaid
with return receipt requested, as follows:

            REPRESENTATIONS AND WARRANTIES OF SELLER AND SHAREHOLDER

         Seller and Shareholder, jointly and severally, represent and warrant
to BearCom and Newco as of the date of this Agreement that:

         SECTION 2.1      CORPORATE EXISTENCE AND POWER; OWNERSHIP.  Seller is
a corporation duly organized, validly existing and in good standing under the
laws of its jurisdiction of incorporation, and has all requisite corporate
power and authority required to carry on its business and to own and lease the
properties it owns and leases.  Seller is duly qualified to do business as a
foreign corporation and is in good standing in each jurisdiction where the
character of the property owned or leased by it or the nature of its activities
makes such qualification necessary, except for those jurisdictions where the
failure to be so qualified would not, individually or in the aggregate, have a
material adverse effect on its Assets, financial condition, prospects or the
results of operations.  Shareholders are the sole record and beneficial owners
of all of the outstanding capital stock of Seller, free and clear of all Liens,
and have been the sole owners since Seller was formed.  Except as identified on
Schedule 2.1, Seller does not have any direct or indirect ownership or other
equity or profit sharing interest in any other entity related to the Business
of Seller.

         SECTION 2.2      AUTHORITY RELATIVE TO THIS AGREEMENT.  Seller and
Shareholder have full power, capacity and authority to execute and deliver this
Agreement and each other Transaction Document to which it is a party and to
consummate the transactions contemplated hereby and thereby (the "Contemplated
Transactions").  The execution and delivery of this Agreement and the
consummation of the Contemplated Transactions to which Seller or Shareholder is
a party have been duly and validly authorized by Seller and Shareholder and no
other proceedings on the part of Seller or Shareholder are necessary to
authorize the execution and delivery by Seller and Shareholder of this
Agreement or the consummation of the Contemplated Transactions to which Seller
or Shareholder is a party.  This Agreement and the other Transaction Documents
to which Seller or Shareholder is a party have been duly and validly executed
and delivered by Seller or Shareholder, as applicable, and (assuming the valid
execution and delivery thereof by the other parties thereto) constitute the
legal, valid and binding agreements of Seller or Shareholder, as the case may
be, enforceable against such party in accordance with their respective terms.

         SECTION 2.3      NO CONFLICTS, CONSENTS.  Neither the execution,
delivery nor performance by Seller or Shareholder of this Agreement nor the
other Transaction Documents to which it or he is a party nor the consummation
of the Contemplated Transactions, will (i) violate any provision of the
Articles of Incorporation or By-laws (or comparable instruments) of Seller;
(ii) require Seller or Shareholder to obtain any consent, approval or action of
or waiver from, or make any filing with, or give any notice to, any
Governmental Body or any other person except as set forth on Schedule 2.3 (the
"Required Consents"); (iii) if the Required Consents are obtained prior to
Closing, violate, conflict with or result in a breach or default under (after
the giving of notice or the passage of time or both), or permit the termination
of, any Contract of a type required to be listed on Schedule 2.11 to which
Seller or Shareholder is a party, or result in the creation of any Lien upon
any of the Assets or the Shareholder's Property pursuant to the terms of any
such Contract; or (iv) if the Required Consents are obtained prior to Closing,
violate any Law or Order of any Governmental Body against, or binding upon,
Seller or upon its Assets or Shareholder's Property.

<PAGE>   10
         SECTION 2.4      CHARTER DOCUMENTS AND CORPORATE RECORDS.  Seller has
heretofore delivered to BearCom true and complete copies of the Articles of
Incorporation and Bylaws, or comparable instruments, of Seller as in effect on
the date hereof.

         SECTION 2.5      TITLE.  Except as set forth on Schedule 2.5, Seller
has good and valid record and marketable title to, and has the full right to
sell, convey, transfer, assign and deliver to Purchaser, all of the Assets free
and clear of any Liens of any kind or nature, and there are no filings in any
registry of deeds in any jurisdiction or under any Uniform Commercial Code or
any similar statute in any jurisdiction showing Seller as debtor, which create
or perfect or which purport to create or perfect any Lien on any of the Assets.
The Assets are all of the assets that are necessary for Purchaser to operate
the Business of Seller in the manner Seller has been operating it.

         SECTION 2.6      FINANCIAL INFORMATION.  Seller has previously
furnished to BearCom true and complete copies of (i) Seller's audited financial
statement at and for the calendar years ended December 31, 1996 (the "1996
Financial Statement") and Seller's unaudited financial statement at and for the
calendar year ended December 31, 1995 (the "1995 Financial Statement")
(collectively the "Annual Statements"), (ii) Seller's unaudited financial
statements at and for each calendar month during 1997 and through December 31,
1997 (the "Interim Statements"), and (iii) all management letters and attorney
audit response letters issued in connection with Seller's financial statements
for each of the periods comprising the Annual Statements and Interim
Statements.  The Annual Statements and Interim Statements have been prepared in
accordance with GAAP consistently applied as set forth in the notes thereto
(except, with respect to the 1995 Financial Statement and the Interim
Statements, as regards footnote disclosure and normal year end adjustments) and
the 1996 Financial Statement was audited by Seller's regularly engaged
certified public accountants.  Each Annual Statement and Interim Statement
presents fairly the financial position of Seller as of its date, and its
earnings, changes in stockholders' equity and cash flow for the periods then
ended.  Each delivered balance sheet included within the Annual Statements and
the Interim Statements fully sets forth all Assets and Liabilities of Seller
existing as of its date which, under GAAP, should be set forth therein, and
each delivered statement of earnings included within the Annual Statements and
the Interim Statements sets forth the items of income and expense of Seller
which should appear therein under GAAP.  All financial and accounting books,
ledgers, accounts and official and other records relating to Seller have been
properly and accurately kept and completed in all material respects.  All
allowances and reserves shown in the Annual Statements and the Interim
Statements are appropriate, reasonable and sufficient to provide for expenses
and losses thereby contemplated including the reserve for all Taxes payable.
Seller is not liable upon or with respect to, or obligated to provide funds in
respect of or under any guarantee.  Except as identified on Schedule 2.6,
Seller does not know of any basis for the assertion of any other Claims or
Liabilities of any nature or in any amount which could have a MATERIAL ADVERSE
EFFECT on Seller, the Assets or Business.  There were not any material items of
revenue or expense which were unusual or of a nonrecurring nature reflected in
the Annual Statements or the Interim Statements.

         SECTION 2.7      LIABILITIES.  Except as and to the extent reflected
in the interim balance sheet of Seller (the "Latest Balance Sheet") at December
31, 1997 (the "Latest Balance Sheet Date") referred to in Section 2.6, or as
described in Schedule 2.7, Seller did not have, as of the Latest Balance Sheet
Date, any material Liabilities or obligations (other than obligations of
continued performance under Contracts and other commitments and arrangements
entered into in the ordinary course of business).  Except as described in
Schedule 2.7, and except for current Liabilities for trade or business
obligations incurred in the ordinary course of the Business of Seller,
consistent with past practice, and Liabilities reflected on any balance sheet
included in the Interim Statements, since the Latest Balance Sheet Date (i)
there has been no material adverse change





                                     - 6 -
<PAGE>   11
in the Assets, Liabilities, Business condition or prospects of Seller; (ii)
except as otherwise disclosed herein, no factor exists or is threatened which
could reasonably be expected to cause such a material adverse change in the
future; and (iii) no dividends or other distributions have been made upon any
shares of capital stock of Seller nor have any shares of capital stock of
Seller been redeemed, retired, purchased or acquired for value by Seller.

         SECTION 2.8      SELLER RECEIVABLES.  Schedule 2.8 sets forth a true
and complete list of Receivables as of the date hereof.  Except as set forth in
Schedule 2.8, to the knowledge of Seller, all Receivables of Seller are valid
and enforceable claims, constitute bona fide Receivables resulting from the
sale of goods and services in the ordinary course of the Business of Seller,
are not subject to any defenses, offsets, returns, allowances or credits of any
kind, and are collectible, subject to reserves for bad debt, as adjusted from
time to time in the ordinary course of business.  Except as set forth on
Schedule 2.8, none of the obligors of the Receivable have given notice that
they will or may refuse to pay the full amount thereof or any portion thereof.

         SECTION 2.9      ABSENCE OF CERTAIN CHANGES.  Since the Latest Balance
Sheet Date, except as set forth in Schedule 2.9, Seller has conducted its
Business in the ordinary course consistent with past practices and there has
not been: (i) any material adverse change in the Assets; (ii) any material
damage, destruction or other casualty loss, condemnation or other taking
affecting the Assets to the extent material to Seller; or (iii) any change in
any method of accounting or accounting practice by Seller.  Except as described
on Schedule 2.9, since December 31, 1997, Seller has not (i) declared, paid or
set aside for payment any dividend or distribution to the Shareholders, (ii)
made any loan or advance to any Shareholder, officer, director or employee,
(iii) redeemed, purchased or otherwise acquired or sold or issued any of its
capital stock or any right to acquire such capital stock, (iv) increased the
compensation of or paid or accrued any bonus to any employee of Seller or its
Affiliates other than in accordance with past established practices or (v) paid
any management or consulting fee or any other amounts to any Shareholder or any
other person related to or affiliated with Seller or any Shareholder.

         SECTION 2.10     SHAREHOLDER'S PROPERTY AND SELLER'S PROPERTY.

                 (a)      Schedule 2.10A sets forth a list and description of
all real property owned by Seller (the "Seller's Property"), which Seller's
Property and Shareholder's Property constitute all of the real property owned,

                 (b)      Seller has good and marketable title to (or valid
leasehold interest in) all Assets and Seller's Property, free and clear of all
Liens except as disclosed in Schedule 2.5 or 2.10B and Shareholder has good and
marketable title to Shareholder's Property, free and clear of all liens except
as described in Schedule 2.5 or 2.10B.

                 (c)      All of the fixed Assets owned or leased by Seller are
in good condition and repair, fit for their intended use in the ordinary course
of business, and to the knowledge of Seller and Shareholder conform in all
respects with all applicable Laws and to the knowledge of Seller and
Shareholder, there are no known latent defects therein.

                 (d)      Parties in Possession.  There are no adverse or other
parties in possession of the Seller's Property or Shareholder's Property, or of
any part thereof, except for Seller's possession of Shareholder's Property.

Property.

                 (g)      Utility Assessments.  To Seller's and/or

assessments are threatened.

                 (h)      Material Adverse Effect on Use.  To Seller's and/or
Shareholder's knowledge there are no circumstances existing that would
materially adversely affect the use or value of Seller's Property or
Shareholder's Property for its existing use which have not been disclosed in
this Agreement or the Schedules.

         SECTION 2.11  CONTRACTS.

                 (a)      Schedule 2.11 sets forth a list of (i) all Contracts

                                INDEMNIFICATION

         SECTION 7.1      SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

                 (a)      Notwithstanding any right of BearCom or Newco fully
to investigate the affairs of Seller and notwithstanding any knowledge of facts
determined or determinable by BearCom or Newco pursuant to such investigation
or right of investigation, BearCom and Newco have the right to rely fully upon
the representations, warranties, covenants and agreements of Seller contained
in this Agreement, or listed or disclosed on any Schedule hereto, as the same
may be modified by any certificate delivered by Seller on or before Closing and
approved by BearCom or Newco, or in any instrument delivered in connection with
or pursuant to any of the foregoing.  All such representations, warranties,
covenants and agreements shall survive the execution and delivery of this
Agreement and the Closing hereunder.  Notwithstanding the foregoing, all
representations and warranties of Seller contained in this Agreement, on any
Schedule hereto or in any instrument delivered in connection with or pursuant
to this Agreement, and the indemnification obligations of Seller in respect of
the matters specified in clauses (i) and (ii) of Section 7.2, shall terminate

1.6 hereof; provided, however, that the liability of Seller shall not terminate
as to any specific claim or claims of the type referred to in Section 7.2
hereof, whether or not fixed as to liability or liquidated as to amount, with
respect to which Seller has been given specific notice on or prior to the date
on which such liabilities would otherwise terminate pursuant to the terms of
this Section 7.1.  Notwithstanding the foregoing, Seller acknowledges that its
obligation to indemnify Purchaser with respect to any Retained Liabilities
shall survive the Closing until the expiration of any applicable statute of
limitations with respect thereto, and such obligation shall not be affected by
the expiration of any representation and warranty of Seller under this Section
7.1(a).

                 (b)      Notwithstanding any right of Seller and Shareholder
fully to investigate the affairs of BearCom and Newco and notwithstanding any
knowledge of facts determined or determinable by Seller or Shareholder pursuant
to such investigation or right of investigation, Seller and Shareholder have
the right to rely fully upon the representations, warranties, covenants and
agreements of BearCom and Newco contained in this Agreement, or listed or
disclosed on any Schedule hereto, as the same may be modified by any
certificate delivered by BearCom, Newco, or either of them on or before Closing
and approved by Seller and Shareholder, or in any instrument delivered in
connection with or pursuant to any of the foregoing.  All such representations,
warranties, covenants and agreements shall survive the execution and delivery
of this Agreement and the Closing hereunder.  Notwithstanding the foregoing,
all representations and warranties of BearCom and Newco contained in this
Agreement, on any Schedule hereto or in any instrument delivered in connection
with or pursuant to this Agreement, and the indemnification obligations of
BearCom and Newco in respect of the matters specified in clauses (i) and (ii)
of Section 7.3 (other than the obligations of Purchaser to pay all or any
portion of the Asset Purchase Price and Shareholder's Purchase Price
(including, without limitation, post-Closing adjustments thereto) becoming due
at or after Closing, and the covenants and agreements of Purchaser contained in
Section 1.8 hereof), shall terminate and expire at the end of the twenty-four
month period specified in Section 1.6 hereof; provided, however, that the
liability of BearCom and Newco shall not terminate as to any specific claim or
claims of the type referred to in Section 7.3 hereof, whether or not fixed as
to liability or





                                     - 18 -

liquidated as to amount, with respect to which BearCom or Purchaser has been
given specific notice on or prior to the date on which such liabilities would
otherwise terminate pursuant to the terms of this Section 7.1.  Notwithstanding
the foregoing, BearCom and Newco acknowledge that the obligation of BearCom and
Newco to indemnify Seller with respect to any Assumed Liabilities and the
breach or default by Purchaser of its obligations to pay all or any portion of
the Asset Purchase Price or the Shareholder's Purchase Price,  (including,
without limitation, post-Closing adjustments thereto) becoming due at or after
Closing, and the covenants and agreements of Purchaser contained in Section 1.8
hereof, shall survive the Closing until the expiration of any applicable
statute of limitations with respect thereto, and such obligation shall not be
affected by the expiration of any representation and warranty of BearCom or
Newco under this Section 7.1(b).

         SECTION 7.2      OBLIGATION OF SELLER TO INDEMNIFY.  Subject to the
provisions of Section 7.5, Seller and Shareholder, jointly and severally, agree
to indemnify, defend and hold harmless BearCom and Newco (and their respective
directors, officers, employees, Affiliates, successors and assigns) from and
against any and all Claims, losses, liabilities, damages, deficiencies,
judgments, settlements, costs of investigation or other expenses (including
interest, penalties and reasonable attorneys' fees and disbursements and
expenses incurred in enforcing this indemnification) (collectively, "Losses")
suffered or incurred by Newco or any of the foregoing persons arising out of
(i) any breach of the representations and warranties of Seller or Shareholder
contained in this Agreement or in the Schedules or any Transaction Document,
(ii) any breach of the covenants and agreements of Seller contained in this
Agreement or in the Schedules or any Transaction Document, (iii) any Retained
Liabilities, (iv) any Liability of Seller for failure to file any federal,
state, local or foreign Tax Return and any Liability for any Taxes relating to
any tax period ending on or prior to the Closing Date, (v) any Liability under
ERISA for any period prior to the Closing relating to any employee of Seller
who is not hired by Purchaser after the Closing, (vi) any Environmental
Liabilities, and (vii) any other actions or omissions of Seller prior to

Liabilities, or (viii) any Liability to Purchaser in connection with any Claim
by Charles Devito arising prior to Closing.

         SECTION 7.3      OBLIGATION OF BEARCOM AND NEWCO TO INDEMNIFY.
BearCom and Newco, jointly and severally, agree to indemnify, defend and hold
harmless Seller and Shareholder (and their respective directors, officers,
employees, Affiliates, successors and assigns) from and against any and all
Losses suffered or incurred by Seller, Shareholder or any of the foregoing
persons arising out of (i) any breach of the representations and warranties of
BearCom or Newco contained in this Agreement or in the Schedules or any
Transaction Document, (ii) any breach of the covenants and agreements of
BearCom or Newco contained in this Agreement or in the Schedules or any
Transaction Document, (iii) any Assumed Liabilities, and (iv) the operations of
Newco from and after the Closing Date.

         SECTION 7.4      NOTICE AND OPPORTUNITY TO DEFEND THIRD PARTY CLAIMS.

                 (a)      Promptly after receipt by any party hereto (the
"Indemnitee") of notice of any demand, claim, circumstance or Tax Audit which
would or might give rise to a claim or the commencement (or threatened
commencement) of any action, proceeding or investigation (an "Asserted
Liability") that may result in a Loss, the Indemnitee shall give prompt notice
thereof (the "Claims Notice") to the party or parties obligated to provide
indemnification pursuant to Section 7.2 or 7.3 (collectively, the "Indemnifying
Party").  The Claims Notice shall describe the Asserted Liability in reasonable
detail and shall indicate the amount (estimated, if necessary, and to the
extent feasible) of the Loss that has been or may be suffered by the
Indemnitee.

                 (b)      Newco may elect to defend, at its own expense and
with its own counsel, any Asserted Liability against Seller or Shareholder
arising out of an Assumed Liability.  If Newco elects to defend such





                                     - 19 -
<PAGE>   24
Asserted Liability, it shall within thirty (30) days (or sooner, if the nature
of the Asserted Liability so requires) notify the Seller of its intent to do
so.  If Newco elects not to defend such Asserted Liability or fails to notify
Seller or Shareholder, as the case may be, of its election as herein provided,
Seller or Shareholder as the case may be, may pay, compromise or defend such
Asserted Liability at the sole cost and expense of Newco.  In all other
circumstances, each party shall be entitled to control any Asserted Liability
against it.  Notwithstanding the foregoing, neither the Indemnifying Party nor
the Indemnitee may settle or compromise any claim over the reasonable written
objection of the other.  For purposes of this paragraph (b), any such objection
made when such settlement would be in accordance with sound business practices
shall be deemed unreasonable.  Provided further, that if any Indemnitee shall
fail to consent to the monetary terms of any proposed settlement or compromise
of any Asserted Liability, the Indemnifying Party shall not thereafter be
obligated to pay the Indemnitee in respect of such Asserted Liability under
this Article 7 in excess of the amount it would have been required to pay to
the Indemnitee in connection with such proposed settlement or compromise.  Any
Losses of any Indemnitee for which indemnification is available hereunder shall
be paid within thirty (30) days following written demand therefor.

         SECTION 7.5      LIMITS ON INDEMNIFICATION.  Notwithstanding anything
contained in this Agreement to the contrary, BearCom's and Newco's remedies
with respect to Losses, and the liability of Seller and Shareholder, as the
case may be, for indemnification arising out of all Losses incurred by
Purchaser shall not exceed, and shall be limited to an amount equal to the
Purchase Price, including the purchase price for the Related Transactions, and
the sums hereafter becoming due to Seller under clauses 1.6(a) and (b) of this
Agreement.

         SECTION 7.6      SOLE AND EXCLUSIVE REMEDY.  The parties agree that
the indemnification provisions of Section 7 shall constitute the sole and
exclusive remedies of the parties in respect to this Agreement and all of the
Contemplated Transactions, other than fraud.

         SECTION 7.7      RIGHT OF OFFSET.  Purchaser may, at its option, apply
or otherwise offset any and all Losses to which it shall be entitled to be
indemnified by Seller and/or Shareholder pursuant to this Article 7 and/or
Section 9.10(b), against payments due to Seller pursuant to this Agreement or
to Shareholder or Condor, Ltd., pursuant to the Related Transactions.

                                 MISCELLANEOUS

         SECTION 9.1      EXPENSES.  Except as otherwise specifically provided

legal, auditing, accounting, consulting, brokerage, regulatory and other
expenses, BearCom will bear the expenses of Newco, and Shareholder will bear
the expenses of Seller, in each case, incurred in connection with the
preparation, due diligence, negotiation, execution and performance of this
Agreement and the Contemplated Transactions.  Notwithstanding the 





                                     - 20 -
<PAGE>   25
foregoing provisions of this Section, all expenses incurred by Seller prior to
the Closing, including but not limited to, legal, auditing, accounting,
consulting, regulatory and other expenses, incurred in the ordinary course of
business, including but not limited to the preparation of Seller's financial
statement at and for the calendar year ended December 31, 1997, shall not be
borne by Shareholder, but shall be borne by Seller, as expenses incurred in the
ordinary course of business.  If any party hereto shall bring an action at law
or in equity to enforce its rights under this Agreement (including an action
based upon a misrepresentation or the breach of any warranty, covenant,
agreement or obligation contained herein), the prevailing party in such action
shall be entitled to recover from the other party its reasonable costs and
expenses incurred in connection with such action (including fees, disbursements
and expenses of attorneys and costs of investigation).  Seller shall be liable
for and shall pay any transfer tax, sales tax and other similar taxes resulting
from consummation of the Contemplated Transactions.  Purchaser shall pay for the
cost of title policy premiums, premiums on customary endorsements and new
surveys for each of Seller's Property and Shareholder's Property.

              MOTOROLA AUTHORIZED TWO-WAY RADIO DEALER AGREEMENT

This Motorola Authorized Two-Way Radio Dealer Agreement including its
attachments ("Agreement") is made and entered into as of the Agreement Date, as
defined below, at Schaumburg, Illinois, by and between MOTOROLA, INC., a
Delaware Corporation having its principal place of business at 1301 E.
Algonquin Road, Schaumburg, Illinois 60196 ("Motorola") and BearCom Operating
L.P., a Partnership of the State of Texas having its principal place of
business at 11545 Pagemill Road, Dallas, TX 75243 ("Dealer").

WHEREAS, for many years Motorola has sold certain communications products
through a direct sales force of Motorola employees, which it has developed and
supported at great expense; and

WHEREAS, Motorola intends to continue direct distribution to customers of
communications equipment and services which because of business or
technological reasons should, in Motorola's judgment, be served by Motorola; and

WHEREAS, Motorola also desires to expand its distribution system to include
Dealer and other resellers to solicit other customers and develop other markets.

THEREFORE, it is hereby agreed as follows:

1.  TERM 

The initial term of this Agreement shall commence as of the Agreement Date and
shall continue for an initial term which expires on December 31 of the calendar
year that the Agreement Date occurs in, unless sooner terminated as provided in
this Agreement. Thereafter, this Agreement shall renew automatically for
successive one-year additional terms unless a written notice of non-renewal is
sent by either party no less than thirty (30) days prior to the expiration date
of the initial or successive term or unless otherwise terminated pursuant to
the terms of this Agreement.
        
Nothing contained in this Agreement shall be deemed to create any express or
implied obligation on either party to renew or extend this Agreement or to
create any right to continue this Agreement on the same terms and conditions
contained herein. Dealer understands that Motorola intends to review its
distribution strategy and the terms and conditions of this Agreement on an
ongoing basis.

2.  PRODUCTS, PRICES, RETAIL SALE ONLY, FINDER FOR SELECTED SERVICES AND DEALER
    LOCATION 

(a)  During the term of this Agreement, Dealer agrees to purchase and Motorola
agrees to sell, in accordance with the terms and conditions of this Agreement,

products ("Products") as listed in the then current Motorola Authorized Two-Way
Radio Dealer Price Book ("Dealer Price Book").
        
(b)  Motorola appoints Dealer as a finder, in accordance with the terms and
conditions of this Agreement for the sale of Motorola network services contracts

and services not listed in the Dealer Price Book to such Motorola office as may

Motorola from time to time to keep Dealer informed about products and services
available, current prices of those products and services to Dealer, available
discounts, delivery schedules and other terms and conditions of sale and doing
business with Motorola. Dealer agrees that the entire contents of the Dealer
Price Book and Attachment B-Finder's Terms are subject to change or withdrawal

the Dealer Price Book and Attachment B-Finder's Terms and the design or
specifications for the Products, at any time, in any way, without liability or
obligations to Dealer or its customers.

lines and services of Motorola and agrees and consents to the limitation of this
Agreement solely to the Products, Network Services, and Maintenance as listed in
the Dealer's Price Book and Attachment B-Finder's Terms. Dealer also

services by other contractual relationships, and Dealer agrees that nothing
contained in this Agreement shall be deemed to create any express or implied
obligation on Motorola to establish any such other contractual relationship with
Dealer.

(f)  Dealer agrees to limit its distribution of the Products purchased under
this Agreement to direct sale by Dealer to customers at retail for end use as
limited by the terms and conditions of this Agreement. Dealer shall sell the
Products and offer Network Services and Maintenance only from the Dealer's
location written above or such other location as is expressly authorized, in
writing, by an authorized Motorola Division General Manager. Dealer shall not
appoint any sales agent or representative (other that its employees) in

in its sole discretion upon a duly executed amendment to this Agreement, may
allow Dealer to appoint specified agents to seek sales of the Products within
Dealer's Area and promotion of Network Services and Maintenance where defined in
Attachment B-Finder's Terms.

its customer, Dealer will notify its customer of the specific requirements,
rights, duties and limitations contained in the Warranty/Warranty Disclaimer,
Software License and Software Warranty/Warranty Disclaimer, Patent, Copyright
and Trademarks, FCC and Other Governmental Matters provisions in Attachment C,
and any other provisions Motorola may from time to time notify Dealer are
required.

Motorola in Motorola's sole and unrestricted discretion, without any liability
or obligation to Dealer, to appoint additional dealers or finders and/or make
direct or indirect sale or distribution of any Motorola products or services,
similar or dissimilar, or any non-Motorola products or services in Dealer's
defined area of primary marketing responsibility and elsewhere, anytime and to
anyone.

connection with this Agreement shall be used solely in furtherance of the
distribution of Motorola Products and services.
        
6.  AREA OF PRIMARY MARKETING RESPONSIBILITY FOR PRODUCTS

necessary in order to encourage Motorola, Dealer, and Motorola's other dealers,

          matter of this Agreement which is determined to be illegal or an
          unfair or deceptive trade practice in violation of any applicable
          federal, state or local law, or which in the opinion of counsel to
          Motorola constitutes such an illegal, unfair, or deceptive act or

any other party in connection with any such cancellations.

Agreement that by their sense and context are intended to survive the
performance thereof by either or both parties shall so survive the completion

              PER UNIT ADMINISTRATIVE PROCESSING CHARGE AMENDMENT
                                       TO
        MOTOROLA AUTHORIZED TWO-WAY RADIO DEALER AGREEMENT ("AGREEMENT")
                                    BETWEEN
                          MOTOROLA, INC. ("MOTOROLA")
                                      AND
                       BEARCOM OPERATING L.P. ("DEALER")
                          DALLAS, TX ("CITY, STATE")

     Effective Motorola execution date shown below, Dealer and Motorola agree
that the following new sections are added to the end of the Agreement:

" AA. Per Unit Administrative Processing Charge

     Among other things, the Agreement provides that Dealer will limit its
distribution of the Products purchased under the Agreement to direct sale by
Dealer to customers at retail for end use as limited by the terms and
conditions of the Agreement, and that Dealer's defined role in Motorola's
distribution system is necessary in order to encourage Motorola, Dealer and
Motorola's other dealers, distributors and resellers to make the distribution
efforts necessary to expand Motorola's distribution of Products and to provide
the highest levels of customer satisfaction.

     Dealer and Motorola agree that Motorola shall incur serious damages if
Dealer's sale of any Products unit fails to comply with the aforementioned
provisions of the Agreement and, further, that the amount of those damages are
uncertain and difficult of estimation because such damages include by way of
illustration but not limitation, Motorola undertaking a variety of record
keeping, administrative and operational activities and the costs and expenses
related thereto for each such breach of the Agreement by Dealer.

     In addition to Motorola's other rights and remedies under the Agreement,
at law or in equity, to compensate Motorola for such damages, Motorola and
Dealer agree that for each such Products unit sale, as stipulated damages and
not as a penalty, on a per Products unit involved in the transaction basis, the
stipulated sum shall be a Per Unit Administrative Processing Charge which shall
consist of the difference between Motorola's Suggested List Price and the
Dealer purchase price listed in the then current Dealer Price Book for each
Products unit involved in each such non-compliant sale ("Per Unit
Administrative Processing Charge"). To assist in the identification of each
Dealer Products unit subject to the Per Unit Administrative Processing Charge,
Dealer shall give to Motorola full cooperation and access to all of Dealer's
books, contracts and records related in any way to Dealer's sale of Products
units, and to furnish to Motorola all other information with respect to its
affairs, as deemed necessary by Motorola, to identify each such Products unit.

     Motorola shall invoice Dealer for each Per Unit Administrative Processing
Charge. Payment for each such invoice shall be due upon Dealer's receipt of
invoice. In the event Dealer fails to pay an outstanding Per Unit
Administrative Processing Charge invoice within thirty (30) days of the date 
such payment is due, in addition to Motorola's other rights and remedies under
the Agreement, at law or in equity, Motorola may withhold any further
processing of any Dealer order for Products until each such payment is made.

BB.  Marketing Report Delinquency Order Hold

     In the event Dealer fails to provide Motorola any marketing report called
for by this Agreement and Dealer fails to cure such failure within fifteen (15)
days of notice of such failure from Motorola then, in addition to Motorola's
other rights and remedies under the Agreement, at law or in equity, Motorola
may withhold any further processing of any Dealer order for Products until each
such report is provided to Motorola as required by the Agreement."

Except as specifically amended above, the Agreement remains in full force and
effect in accordance with its terms and conditions.

     Effective the Motorola Signature Date shown below, Motorola and Dealer
agree to amend the Agreement as follows:

     A.   Section 7 of the Agreement is entitled "Sales Performance". The third
paragraph of subparagraph (b) of Section 7 which begins "Due to such things as
the......." and ends ".......catalog sales or similar activities." is replaced
in its entirety with the following:

     "Due to such things as the importance of customer contact in connection
     with the sales of the Products, Dealer shall not promote, advertise, or
     sell the Products outside of Dealer's Area through mail order, phone bank
     solicitation, catalogue sales, or similar activities. "Similar activities"
     include but are not limited to the promotion, advertisement or sale of the
     Products through use of any type of on-line computer service (e.g., World
     Wide Web, Internet, etc.).

     Except as amended by the foregoing, the Agreement remains in effect in
accordance with all its existing terms, conditions and amounts.

                RADIUS COMMUNICATION PRODUCTS RESELLER AGREEMENT



     This Radius Communication Products Reseller Agreement ("Agreement") is
made and entered into as of SEP 20 1996 ("Agreement Date") at Schaumburg,
Illinois, by and between MOTOROLA, INC., a Delaware Corporation having a
principal place of business at 1301 E. Algonquin Road, Schaumburg, Illinois
60196 ("Motorola" or "Seller") and BEARCOM OPERATING L.P. a PARTNERSHIP with a
principal place of business at 11545 PAGEMILL ROAD, DALLAS, TX  75243 ("Buyer"
or "Reseller").

     1.   TERM, PRODUCTS, RETAIL SALE ONLY, AND SALES AGENTS.

          The initial term of this Agreement shall commence as of SEP 20 1996
and shall continue for a term expiring on June 30th of each year unless sooner
terminated as provided in this Agreement. Thereafter, this Agreement shall
renew automatically for successive one-year additional terms unless terminated
by either party in writing no less than thirty days prior to the expiration
date of the initial or any additional term or unless otherwise terminated
pursuant to the terms of this Agreement.

          During the term of this Agreement, Buyer agrees to purchase and
Seller agrees to sell selected Radius Communication Products as listed on
Attachment A to this Agreement ("Products"). Motorola in its sole discretion
may revise the list of selected Products from time to time without any
liability to Buyer. Also in its sole discretion, Motorola may discontinue the
production or sale or modify the design or material specifications of any
Products or parts of any Products without any liability or obligations to Buyer
or its customers.

          Buyer specifically acknowledges the existence of other products and
product lines of Motorola and agrees and consents to the limitation of this
Sales Agreement solely to selected Motorola Radius Communication Products as
listed on Attachment A, Products and Pricing Schedule, attached to this
Agreement and made a part of it.

          Buyer shall sell the Products purchased under this Agreement at
retail sale only, (i.e., to end users).

          Additionally, Buyer shall refrain from appointing without the prior
written approval of Motorola any sales agent or representative (other than its
employees) in connection with the performance of this Agreement. In the event
that Motorola grants such approval, it is understood that such appointment
shall be made only in the name and for the account of Buyer and shall be for a
term no greater than the term of this Agreement. Buyer shall not grant to such
sales agent or representative any rights greater than those which are granted
by Motorola to Buyer under this Agreement. Buyer shall also impose on such
sales agent and representative the same obligations as Motorola has imposed on
Buyer under this Agreement for the purpose of protecting the goodwill of
Motorola and the Products.

          Buyer shall provide Motorola with information in detail satisfactory
to Motorola regarding any sales agent or representative proposed by Buyer for
appointment.

     2.   PRICES.

          The prices for the applicable quantity of Products purchased pursuant
to this Agreement shall be as set forth on the Pricing Schedule which is
attached to this Agreement as Attachment A, Products and Pricing Schedule. Such
prices are subject to change upon thirty days written notice to Buyer.

     3.   ORDERS, ACCEPTANCE, CREDIT APPROVAL.

          Purchase and sale shall occur only by Motorola's acceptance of Orders
submitted by Buyer. An order may be submitted on the Reseller Order form
attached to this Agreement as Attachment B and incorporated by reference into
it. Such form may be amended from time to time by Motorola. Facsimile, telegraph
and verbal orders may also be submitted. Acceptance shall be documented by a
Motorola invoice sent to Buyer. Buyer acknowledges and agrees that the invoice
is accurate and final unless objected to in writing within ten days of receipt
by Buyer.

          Acceptance shall be only upon the terms and conditions of this
Agreement and the listed Attachments. The only effect of any terms and
conditions in Buyer's purchase orders or elsewhere shall be to request the time
and place of delivery and number of Products to be delivered, but they shall
not change, alter or add to these terms and 


                                      -1-

<PAGE>   4
conditions in any way. One of the conditions of acceptance is Buyer's obtaining
and maintaining credit approval from Motorola. Buyer shall provide Motorola
with financial information and statements as requested by Motorola to obtain
and maintain Buyer's credit approval.

     4.   CANCELLATION.

          Buyer may cancel an individual order by giving Motorola notice of
such cancellation which notice must be received by Motorola at least six or
more days prior to the scheduled shipping date of such order. Motorola shall
not cancel an individual order when the notice is received by Motorola within
five days of the scheduled shipping date of the order.

     5.   SHIPPING, DELIVERY, PAYMENT, TITLE AND SECURITY.

          (a)  Shipping and handling charges shall be as set forth in
Attachment A. Such shipping and handling charges are subject to change upon
thirty days written notice to Buyer.

          (b)  Each delivery will be separately invoiced without regard to
other deliveries. Payment for each invoice will be according to the payment
terms set forth in Attachment A. Such payment terms are subject to change upon
thirty days written notice to Buyer.

          (c)  Shipping or delivery dates are best estimates only. Motorola
reserves the right to make deliveries in installments and the contract shall be
severable as to such installments. Delivery delay or default of any installment
shall not relieve Buyer of its obligation to accept and pay for remaining
deliveries. IN NO EVENT SHALL MOTOROLA BE LIABLE FOR INCREASED COSTS, LOSS OF
PROFITS OR GOODWILL OR ANY OTHER INCIDENTAL OR CONSEQUENTIAL DAMAGES DUE TO
LATE OR NONDELIVERY OF PRODUCTS.

          (d)  Title to Products sold and risk of loss shall pass to 
Buyer at the shipping point. Buyer grants to Motorola a security interest in
and lien upon all of Buyer's now existing or hereinafter acquired inventory of
the Products and all of Buyer's accounts, chattel paper, instruments, contract
rights, general intangibles, accounts receivable and the proceeds thereof now
existing or hereinafter arising out of Buyer's sale or other disposition of the
Products. Buyer agrees to cooperate in whatever manner necessary to assist
Motorola in perfecting and recording such security interest and lien by
completing the UCC 1 form attached to this Agreement as Attachment C and such
other security as Motorola may from time to time request, all such security
interests and liens to become part of this Agreement.

     6.   WARRANTY.

          Motorola warrants the Products in accordance with the Limited
Warranty attached to the Agreement as Attachment D and made a part of it and
makes no representation or warranty of any other kind. This Limited Warranty is
extended by Motorola not to Buyer but to the original purchaser of the Products
from Buyer and is not assignable or transferable to subsequent purchasers.
Buyer, upon the sale of the Products, is authorized to provide this Limited
Warranty to its customers and shall deliver to its customers the printed
Limited Warranty attached hereto as Attachment D. Buyer shall not issue any
warranties or guarantees with respect to the Products which purport to obligate
Motorola to any person or entity other than the aforesaid Limited Warranty
furnished for the Products by Motorola. Such Warranty may be changed from time
to time by Motorola on one hundred twenty days prior written notice to Buyer.
SUCH WARRANTY IS GIVEN IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED,
WHICH ARE SPECIFICALLY EXCLUDED, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. THE RADIUS
COMMERCIAL WARRANTY DOES NOT APPLY OUTSIDE OF THE FIFTY UNITED STATES AND THE
DISTRICT OF COLUMBIA.

     7.   PATENT, COPYRIGHT AND TRADEMARKS.

          (a)  INDEMNIFICATION. Motorola agrees to defend, at its expense, any
suits against Buyer based upon a claim that any Motorola-manufactured Products
furnished hereunder directly infringe a U.S. patent or copyright and to pay
costs and damages finally awarded in any such suit, provided that Motorola is
notified promptly in writing of the suit and, at Motorola's request and at its
expense, is given control of said suit and all requested assistance for defense
of same. If the use or sale of any such Product(s) furnished hereunder is
enjoined as a result of such suit, Motorola, at its option and at no expense to
Buyer, shall obtain for Buyer the right to use or sell such Product(s), or
shall substitute an equivalent Product reasonably acceptable to Buyer and shall
extend this indemnity thereto, or shall accept the return of such Product(s)
and reimburse Buyer the purchase price therefor less a reasonable charge for
reasonable wear and tear. This indemnity does not extend to any suit based upon
any infringement or alleged infringement of any patent or copyright by the
combination of any such Product(s) furnished hereunder and other elements nor
does it extend to any such Product(s) of Buyer's design or formula. The
foregoing states the entire liability of Motorola for patent or copyright
infringement. IN NO EVENT SHALL MOTOROLA BE LIABLE FOR INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING FROM INFRINGEMENT OR ALLEGED INFRINGEMENT OF
PATENTS OR COPYRIGHTS.

          (b)  COPYRIGHTS AND MASK WORKS. Laws in the United States and other
countries preserve for Motorola certain exclusive rights in the Motorola
Software, mask works and other works of authorship furnished


                                      -2-
<PAGE>   5
hereunder, including without limitation the exclusive right to prepare works
derived from same, reproduce same in copies and distribute copies of same. Such
Motorola Software, mask works and other works of authorship may be used in and
redistributed only with the Products associated with same. No other use,
including without limitation reproduction, modification or disassembly of such
Motorola Software, mask works or other works of authorship or exercise of
exclusive rights in same, is permitted.

          (c)  REVERSE ENGINEERING.     Buyer acknowledges Motorola's claim
that the Motorola Software and Products furnished hereunder contain valuable
trade secrets of Motorola and therefore agrees that it will not translate,
reverse engineer, de-compile or disassemble or make any other unauthorized use
of such Motorola Software and Products. Since unauthorized use of such Motorola
Software and Products will greatly diminish the value of such trade secrets and
cause irreparable harm to Motorola, Buyer agrees that Motorola, in addition to
any other remedies it may have, shall be entitled to equitable relief to
protect such trade secrets, including without limitation temporary and
permanent injunctive relief without the proving of damage by Motorola.

          (d)  TRADEMARK AND PROPRIETARY MARKS.

               (1)  The Products shipped under the terms and conditions of this
Agreement will carry Motorola's trademark and proprietary marks or such other
logo or proprietary marks as Motorola may expressly agree to in writing prior
to any use of such other logo or mark.

               (2)  Buyer hereby acknowledges the validity of the trademark
"RADIUS" as well as of all other proprietary marks which are affixed to the
Motorola Products and agrees that the aforesaid trademark and proprietary
marks are and shall remain the property of Motorola.

               (3)  Buyer shall not do anything to infringe upon, harm, or
contest the validity of the aforesaid trademark or other proprietary marks of
Motorola.

               (4)  Buyer may use the trademark "RADIUS" in connection with the
promotion or sale of such Motorola Products and state that such Products are
manufactured by Motorola. Except as Motorola may otherwise specifically
provide, such promotion shall be at Buyer's sole cost and expense.

               (5)  Buyer agrees that it shall not use the trademark "RADIUS" as
part of the name under which it conducts business.

               (6)  Permission to display the word "MOTOROLA", "RADIUS" or any
other proprietary word or symbol owned by Motorola or its affiliates, is only
as stated above and it is expressly understood that nothing herein shall grant
to Buyer any right, title or interest in the words "MOTOROLA", "RADIUS" (either
alone or in association with other words, names or symbols), or in the
corporate name of Motorola, or any part thereof or in any other trademark or
trade name adopted by Motorola or its affiliates.

               (7)  In order that Motorola may protect its trademarks, trade
names, corporate slogans, goodwill and product designations, Buyer shall not
use any such marks, names, slogans, or designations in any advertising copy,
promotional material, signs or other written or printed material except in a
form specially approved in writing by Motorola.

               (8)  If, as set forth in subparagraph (4) above, any such mark
is used in signs, advertising or in any other manner by Buyer, Buyer will, upon
termination or expiration of this Agreement, immediately discontinue all such
use or display.

     (e)  LICENSE DISCLAIMER. Except for the right to use the Motorola Software
and Products for the purpose provided herein which arises by operation of law
and except as expressly provided in the Agreement, nothing contained in this
Agreement shall be deemed to grant to Buyer either directly or by implication,
estoppel or otherwise, any license or right under any patents, copyrights, 
trademarks or trade secrets of Motorola or any third party.

     8.   USE OF BUYER'S NAME.

          Motorola may advertise the Products subject to this Agreement and
Motorola may with Buyer's consent use Buyer's name in such advertising. To
assist Buyer in promoting sales Motorola may furnish such promotional
literature and other advertising aids as Motorola deems necessary.

     9.   TERM, TERMINATION.

          This Agreement will begin on the Agreement Date and is effective for
the term indicated in Paragraph 1 unless terminated sooner according to this
Paragraph. This Agreement may be terminated:

          (a)  by either party without cause upon sixty days prior written
notice to the other party; or

          (b)  by Motorola immediately upon the occurrence of any of the
following events:

               (1)  a breach of any term or provision of Paragraphs 7 or 15;

               (2)  a change in the control or management of Buyer which is
unacceptable to Motorola;

               (3)  Buyer ceasing to function as a going concern, declaring
bankruptcy, having a receiver for it appointed, or otherwise taking advantage
of any insolvency law;

               (4)  Buyer's failure to cure a breach of this Agreement, other
than a breach of Paragraphs 7 or 15, within thirty days after Motorola's
written notification to Buyer of such breach;


                                      -3-

<PAGE>   6
          (5)  the untrue statement of a material fact, or omission to state a
material fact necessary to make the statements contained therein not misleading,
in any written information or statement furnished by Buyer to Motorola in
connection with this Agreement or the performance of this Agreement;

          (6)  Buyer's engaging in any practice with respect to the Products
which is determined to be an illegal or unfair trade practice in violation of
any applicable Federal, State or Local law, or which in the opinion of counsel
to Motorola is an illegal or unfair trade practice in violation of any
applicable Federal, State or Local law;

          (7)  any direct or indirect sale of Products by Reseller outside of
the fifty United States and the District of Columbia which are not in
accordance with Paragraph 20 of this Agreement; or

          (8)  any use by Buyer of any sales agent or representative (other
than its employees) in connection with the performance of this Agreement
without the prior written approval of Motorola.

     (c)  Nothing contained in this Agreement shall be deemed to create any
express or implied obligation on either party to renew or extend this Agreement
or to create any right to continue this Agreement on the same terms and
conditions contained in it.

10.  EFFECT OF TERMINATION OR EXPIRATION.

     (a)  Neither Motorola nor Buyer shall be liable to the other, or to any
other party, buy virtue of the termination or expiration of this Agreement for
any reason whatsoever, or by virtue of the cancellation of any orders for the
Products that are undelivered on the effective date of any termination of this
Agreement, including, but not limited to, any claim for loss of profits or
prospective profits for anticipated sales of Radius Communication Products.

     (b)  All sums owed by either party to the other shall become due and
payable immediately upon termination of this Agreement.

     (c)  Upon termination or expiration of this Agreement, Buyer shall, within
two working days of such termination or expiration, deliver to such address as
Motorola shall specify all Motorola property, including but not limited to all
catalogs, drawings, designs, engineering photographs, samples, literature, sales
aids and other confidential business information and trade secrets of Motorola
in Buyer's possession.

     (d)  Upon expiration or termination, Motorola shall be relieved of any
obligation to make any further shipments under this Agreement and, with respect
to termination, may cancel all of Buyer's unshipped orders for the Products,
irrespective of previous acceptance by Motorola. Motorola shall have no
obligation or liability to Buyer or its prospective customers in connection
with any such cancellations.

     (e)  Motorola's acceptance of any order by Buyer for the Products after
the termination or expiration of this Agreement shall not be construed as a
renewal or extension of this Agreement, nor as a waiver of termination.

     (f)  The terms, provisions, representations and warranties contained
in this Agreement that by their sense and context are intended to survive the
performance thereof by either or both parties shall so survive the completion
of performances and termination or expiration of this Agreement, including the
making of any and all payments due under this Agreement.

11.  TAXES.

     Except for the amount, if any, of Federal, State, or Local taxes stated in
Attachment A, the prices set forth herein are exclusive of any amount for
Federal, State, or Local excise, sales, use, property, retailers' occupation or
similar taxes. If any such excluded taxes are determined to be applicable to
this transaction or if Motorola is required to pay or bear the burden of such
taxes, the prices set forth herein shall be increased by the amount of such
taxes and any interest or penalty thereon, and Buyer shall pay to Motorola the
full amount of any such increase no later than ten days after receipt of an
invoice for such taxes, or Buyer may provide Motorola an executed resale
exemption certificate as required by state tax authorities to establish Buyer's
tax exempt status as a reseller under this Agreement.

12.  EXCUSABLE DELAYS.

     Motorola shall not be liable for any delay or failure to perform due to
any cause beyond its control. Causes include but are not limited to strikes,
acts of God, acts of the Buyer, interruptions of transportation or inability to
obtain necessary labor, materials or facilities, or default of any supplier.
The delivery schedule shall be considered extended by a period of time equal to
the time lost because of an excusable delay. In the event Motorola is unable to
wholly or partially perform because of any cause beyond its control, Motorola
may terminate any order without any liability to Buyer.

13.  WAIVER.

     The failure of either party to insist in any one or more instances upon
the performance of any of the terms, covenants, or conditions in this
Agreement, or to exercise any right under this Agreement, shall not be construed
as a waiver or relinquishment of the future performance of any such term,
covenant, or condition or the future exercise of any such right but the
obligation of each party with respect to such future performance shall continue
in full force and effect.
                                      -4-

14.  FCC AND OTHER GOVERNMENT MATTERS.

     Buyer or the end-user is solely responsible for obtaining any licenses or
other authorizations required by the Federal Communications Commission ("FCC")
or any other Federal, State or Local governmental agency. Buyer is solely
responsible for complying with applicable FCC rules and regulations and the
applicable rules and regulations of any other Federal, State or Local
governmental agency. Neither Motorola nor any of its employees is an agent of
Buyer or the end-user in FCC or other governmental matters.

15.  COMPLIANCE WITH LAW.

     Buyer shall at all times conduct its efforts hereunder in strict
accordance with all applicable Federal, State and Local laws and regulations
and with the highest commercial standards. Buyer agrees to promptly comply with
any notices received from Motorola regarding compliance with any State or
Federal law including but not limited to laws regarding warranty or consumer
protection.

16.  COMMUNICATIONS SERVICES.

     Buyer agrees that communications services such as Specialized Mobile
Radio, community repeater or other communications services are not provided
under the Agreement. Buyer or the end-user must enter into separate agreements
with the service provider(s) to obtain such services. MOTOROLA DISCLAIMS
LIABILITY FOR RANGE, COVERAGE, AVAILABILITY OR OPERATION OF ANY SYSTEM.

17.  LIMITATIONS.

     (a)  LIMITATION OF LIABILITY.  EXCEPT FOR PERSONAL INJURY AND EXCEPT AS
PROVIDED FOR IN THE SECTION "PATENT, COPYRIGHT AND TRADEMARKS", MOTOROLA'S
TOTAL LIABILITY ARISING OUT OF OR RELATED TO THIS AGREEMENT WHETHER FOR BREACH
OF CONTRACT, WARRANTY, MOTOROLA'S NEGLIGENCE, STRICT LIABILITY IN TORT OR
OTHERWISE, IS LIMITED TO THE PRICE OF THE PARTICULAR PRODUCTS SOLD HEREUNDER
WITH RESPECT TO WHICH LOSSES OR DAMAGES ARE CLAIMED. BUYER'S SOLE REMEDY IS TO
REQUEST MOTOROLA AT MOTOROLA'S OPTION TO EITHER REFUND THE PURCHASE PRICE, OR
REPAIR OR REPLACE PRODUCTS THAT ARE NOT AS WARRANTED. IN NO EVENT, WHETHER FOR
BREACH OF CONTRACT, WARRANTY, MOTOROLA'S NEGLIGENCE, STRICT LIABILITY IN TORT,
OR OTHERWISE, WILL MOTOROLA BE LIABLE FOR INCIDENTAL, SPECIAL OR CONSEQUENTIAL
DAMAGES, INCLUDING, BUT NOT LIMITED TO, FRUSTRATION OF ECONOMIC OR BUSINESS
EXPECTATIONS, LOSS OF PROFITS, LOSS OF DATA, COST OF CAPITAL, COST OF
SUBSTITUTE PRODUCT(S), FACILITIES OR SERVICES, DOWNTIME COST OR ANY CLAIM
AGAINST BUYER BY ANY OTHER PARTY.

     (b)  INSURANCE. IT IS FURTHER UNDERSTOOD THAT MOTOROLA IS NOT AN INSURER
AND THAT BUYER SHALL OBTAIN ALL INSURANCE, IF ANY, THAT IS DESIRED AND THAT
MOTOROLA DOES NOT REPRESENT OR WARRANT THAT MOTOROLA PRODUCTS WILL AVERT OR
PREVENT OCCURRENCES, OR THE CONSEQUENCES THEREFROM, WHICH ARE MONITORED,
DETECTED OR CONTROLLED WITH USE OF THE PRODUCTS.

     (c)  TIME TO SUE. EXCEPT FOR MONEY DUE UPON OPEN ACCOUNT, NO ACTION SHALL
BE BROUGHT FOR ANY BREACH OF THIS AGREEMENT MORE THAN TWO YEARS AFTER THE

PROVIDED BY APPLICABLE LAW.

     (d)  NO REPRESENTATIONS. THE ISSUANCE OF INFORMATION, ADVICE, APPROVALS,
INSTRUCTIONS OR COST PROJECTIONS BY MOTOROLA'S SALES PERSONNEL OR OTHER
REPRESENTATIVES SHALL BE DEEMED EXPRESSIONS OF PERSONAL OPINION ONLY AND SHALL

SAME IS IN WRITING AND SIGNED BY AN OFFICER OF MOTOROLA WITH THE EXPLICIT
STATEMENT THAT IT CONSTITUTES AN AMENDMENT TO THIS AGREEMENT.

its inventory of Products and provide Seller, in a form to be provided by
Seller, a monthly usage forecast to assist Seller in maintaining an orderly
production flow for the purpose of meeting Buyer's delivery requirements.
Buyer's failure to provide such information may be considered cause by Seller
for excusable delivery delay.

19.  PARTY RELATIONSHIP.

     This Sales Agreement does not create an agency, joint venture or
partnership between Buyer and Seller. Neither party shall impose or create any
obligation or responsibility, express or implied, or make any promises,
representations or warranties on behalf of the other party, other than as
expressly provided herein.

20.  SALES OUTSIDE OF THE UNITED STATES.

     In the event that Reseller elects to sell Motorola Radius Products or
services to entities outside of the United States, Reseller does so solely at
its own option and risk. Reseller remains solely and exclusively responsible
for compliance with all statutes and regulations governing sales to foreign
entities. These statutes include, but are not limited to those of the United
States Government including United States export control law and those of the
foreign entity involved, as well as those of certain international
organizations whose function it is to regulate such sales, such as The
Coordinating Committee for East West Trade. Radius makes no representations,
certifications or warranties whatsoever with respect to the ability of its
goods, services or prices to satisfy any such statutes or regulations. Failure
of the Reseller to conduct any sales to foreign entities in strict accordance
with all statutes and regulations of all governments and organizations
involved shall constitute a material breach of this Agreement. The Radius
Limited Warranty does not apply outside of the fifty United States and the
District of Columbia.

21.  SALES TO THE U.S. GOVERNMENT.

     In the event that Reseller sells Products or services to the U.S.
Government, or to a prime contractor selling to the U.S. Government, Reseller
does so at its own option and risk. Reseller remains solely and exclusively
responsible for compliance with all statutes and regulations governing sales to
the U.S. Government. Motorola Radius makes no representations, certifications or
warranties whatsoever with respect to the ability of its goods, services or
prices to satisfy any such statutes or regulations. Failure of the Reseller to
conduct any sales to the U.S. Government, or to U.S. Government prime
contractors, in strict accordance with U.S. law shall constitute a material
breach of this Agreement.

22.  GENERAL.

     (a)  Except for changes by Motorola in the various attachments to this
Agreement or in the price, design, terms of sale, warranty, or specifications
of the Products, any amendment to this Agreement must be in writing and signed
by an authorized representative of Motorola and Reseller.

     (b)  Buyer acknowledges that it has read and understands these terms and

other communications between the parties relating to the subject matter hereof.

     (c)  This Agreement is binding upon and shall inure to the benefit of the
parties hereto and their respective heirs, executors, legal representatives,

written consent of Seller.

     (d)  If any provision of this Agreement is contrary to, prohibited by or
held invalid by any law, rule, order or regulation of any government or by the

                             MASTER AMENDMENT NO. 1
                                       to
         MOTOROLA INC. RADIUS COMMUNICATION PRODUCTS RESELLER AGREEMENT
                                 ("Agreement")
                                    between
                          MOTOROLA, INC. ("Motorola")
                                      and


                      BearCom Operating L.P. ("Reseller")

                           Dallas, TX (City, State")


     Effective the Motorola execution date shown below, Reseller and Motorola
agree that the Agreement is changed as follows:

A.   Subparagraph 9(b)(8) of the Agreement entitled, "TERM, TERMINATION" is
replaced in its entirety with the following:


          "any direct or indirect sale of the Products by Reseller that does
not comply with Reseller's covenant to limit its distribution of the Products
purchased under this Agreement to direct sale by Reseller only to customers at
retail for end use as limited by the terms and conditions of this Agreement."

B.   The following new sections are added to the end of the Agreement:

"    AA.  RESELLER MARKETING REPORTS

          Reseller shall provide to Motorola by the first Wednesday of each
month during any term of this Agreement, a marketing report ("Reseller
Marketing Report") by customer name setting forth the number of units of each
of the Products sold by Reseller during the preceding month, including dollar
volume of sales by ultimate destination zip code, customer Standard Industrial
Code ("SIC"), or other categories or industry groupings requested by Motorola.
Reseller shall provide said information by completing and sending to Motorola a
marketing report in whatever form requested by Motorola. The current form of
marketing report is attached to this amendment as Attachment 1-Reseller
Marketing Report Form.

          In the event Reseller fails to provide Motorola any marketing report
called for by this Agreement and Reseller fails to cure such failure within
fifteen (15) days of notice of such failure from Motorola then, in addition to
Motorola's other rights and remedies under the Agreement, at law or in equity,
Motorola may withhold any further processing of any Reseller order for Products
until each such report is provided to Motorola as required by the Agreement.

BB.  Per Unit Administrative Processing Charge

          Reseller agrees to limit its distribution of the Products purchased
under the Agreement to direct sale by Reseller to customers at retail for end
use as limited by the terms and conditions of the Agreement. Reseller
acknowledges that its defined role in Motorola's distribution system is
necessary in order to encourage Motorola, Reseller and Motorola's other
resellers, distributors and dealers to make the distribution efforts necessary
to expand Motorola's distribution of Products and to provide the highest levels
of customer satisfaction.


                                                              (See Reverse Side)
<PAGE>   2
          Reseller and Motorola agree that Motorola shall incur serious damages
if Reseller's sale of any Products unit fails to comply with the aforementioned
provisions of the Agreement and, further, that the amount of those damages are
uncertain and difficult of estimation because such damages include by way of
illustration but not limitation, Motorola undertaking a variety of record
keeping, administrative and operational activities and the costs and expenses
related thereto for each such breach of the Agreement by Reseller.

          In addition to Motorola's other rights and remedies under the
Agreement, at law or in equity, to compensate Motorola for such damages,
Motorola and Reseller agree that for each such Products unit sale, as
stipulated damages and not as a penalty, on a per Products unit involved in the
transaction basis, the stipulated sum shall be a Per Unit Administrative
Processing Charge which shall consist of the difference between Motorola's
Suggested List Price and the Reseller purchase price listed in Motorola's then
current Reseller Price Book for each Products unit involved in each such
non-compliant sale ("Per Unit Administrative Processing Charge"). To assist in
the identification of each Reseller Products unit subject to the Per Unit
Administrative Processing Charge"). To assist in the identification of each
Reseller Products unit subject to the Per Unit Administrative Processing
Charge, Reseller shall give to Motorola full cooperation and access to all of
the Reseller's books, contracts and records related in any way to Reseller's
sale of Products units, and to furnish to Motorola all other information with
respect to its affairs, as deemed necessary by Motorola, to identify each such
Products unit.

          Motorola shall invoice Reseller for each Per Unit Administrative
Processing Charge. Payment for each such invoice shall be due upon Reseller's
receipt of invoice. In the event Reseller fails to pay an outstanding Per Unit
Administrative Processing Charge invoice within thirty (30) days of the date
such payment is due, in addition to Motorola's other rights and remedies under
the Agreement, at law or in equity, Motorola may withhold any further
processing of any Reseller order for Products until such payment is made."



C.    This Master Amendment No. 1 replaces and supercedes any existing
amendment to the Agreement which had as its purpose an amendment to Paragraph
9(b)(8) of the Agreement. Upon the Motorola execution date shown below, any such
existing amendment between Reseller and Motorola is no longer of any force or
effect.

Except as specifically amended above, the Agreement remains in full force and
effect in accordance with all its terms, conditions and amounts.
