Item 1.    BUSINESS

           Overview of the Company

           Geotek Communications, Inc. (the "Company" or "Geotek") is a provider
of mobile logistics systems operating over the Company's proprietary network, a
spectrum-efficient, high quality, 900 MHz integrated digital voice and data
wireless communication network which is based on frequency hopping, multiple
access technology (the "FHMA(R) Network"). The Company's core product is the
Driver Logistics(TM) System, a motor vehicle-based intelligence system designed
to improve the productivity of the fleet driver.


           Geotek markets Driver Logistics Systems in the 11 markets in which it
operates FHMA Networks. The Company maintains specialized mobile radio licenses
("SMR") in over 40 metropolitan trading areas throughout the United States.
During 1997, the Company devoted, and expects to continue to devote, substantial
financial and management resources to continue developing and implementing its
Driver Logistics Systems and network technology.

           The Driver Logistics System integrates voice and data communications,
hardware and specialized software applications with the Company's proprietary
digital voice and packet data network. The system allows users to increase the
productivity of drivers in the field by organizing work schedules, assigning
jobs to mobile workers, tracking work status and completion, sending and
receiving directions, locating stolen and lost vehicles, verifying transactions
and communications among mobile work groups. The Company believes that mobile
fleets, with their dynamic job scheduling and rapid response requirements stand
to benefit the most from the use of the Driver Logistics System.

Background

            During a substantial portion of 1997, the Company engaged in two
business activities: wireless communications and communications products. In
late 1997, the Company announced its intent to realign its operations to focus
on its wireless communications activities in the United States. Consistent with
this change in focus, on November 26, 1997, the Company discontinued its
communications products segment and sold Bogen Communications International,
Inc. ("BCI"), for $18.5 million. BCI was primarily engaged in the development,
manufacturing, and marketing of telephone peripherals and sound and
communications equipment. (See "Discontinued Operations" below.)

           During 1997, Geotek's wireless communications subsidiaries provided
mobile voice and data services to businesses in the United States, the United
Kingdom and Germany. The Company and its affiliates held licenses and network
interests in the United States, the United Kingdom, Germany, Korea, Canada and
Argentina. In February 1998, the Company sold both its interest in its German
joint venture ("Terrafon") and its wholly-owned subsidiary in the United
Kingdom, National Band Three Ltd. ("NB3") for DM7 million and $82 million
respectively. (See "International Operations" below). During 1997, the Company's
wireless communications subsidiaries also marketed and sold FHMA digital network
equipment to network operators and equipment suppliers in Korea (See
"International Operations" below).

           The Company is incorporated under the laws of the State of Delaware.
Its principal executive offices are located at 102 Chestnut Ridge Road,
Montvale, NJ 07645 and its telephone number is (201) 930-9305.

The 1998 Market Focus


           The Company is focused on the substantial market for mobile
logistics. As part of its effort to engage the mobile marketplace, during the 
first quarter of 1998, the Company announced both a corporate repositioning and
a major branding initiative under the concept of "WorkPower for the Road(TM)."
The Company's Driver Logistics System is designed to provide the tools for
increasing the productivity of drivers, while reducing errors, late deliveries,
and wasted trips. The Company believes that many businesses will seek to realize
the value associated with improving driver productivity.

The Driver Logistics System

           The five key features to the Geotek Driver LogisticsSystem are: 1)
navigation to aid on time arrival, improve routing, and increase customer
service; 2) safety and security to protect drivers, their passengers, their
payloads, and their vehicles; 3) task processing to simplify paperwork and
automate routine tasks; 4) driver well-being to relieve driver stress and
fatigue and to enhance, alertness; and 5) communications to provide real-time
voice and data transmissions between drivers and their key contacts.

           The Company's core product offering, the Driver Logistics System(TM)
1000, is a restructured, upgraded and integrated system that includes
hardware, software applications, network usage, installation, training, and
maintenance and is sold under a multi-year contract. The Driver Logistics System
1000 software, "WorkPak(TM), which is included in the package, is a software
suite that runs on the Windows 95(R)operating environment and is planned to
contain the following software applications, including:

o   OfficeLine(TM)- two-way telephony, two-way messaging, and digital two-way
    dispatch radio services.

o   OfficeLine Messaging - allows users to send and receive text from mobile
    workers. Messages can be stored in memory for recall at any time. Message
    receipt can be confirmed and messages which are not received, are resent
    until received. All messages are time and date-stamped for accurate
    communications records.

o   OfficeLine Voice - allows dispatchers to communicate immediately with
    individuals or groups and to log these transmissions. Two-way cellular-like
    telephony features include speed dialing, last number redial,
    previously-dialed number memory, and dual-tone multi-frequency (DTMF)
    capabilities during active telephone calls. All voice communications are
    logged into the system for reporting purposes.

o   JobSMART(TM) - a fleet and driver optimization tool for real-time job
    assignment and tracking. It allows dispatchers to schedule assignments for
    the entire mobile fleet, track their progress, identify problems as they
    occur, and update the driver's schedule throughout the day. This function
    organizes the workday more effectively to enable drivers to do more in less
    time.

o   DriveGuide(TM)- a real time GPS-based vehicle location system that allows
    dispatchers to locate their fleet vehicles on the Driver Logistics
    WorkStation(TM) at any time. The system uses detailed electronic maps and
    global positioning satellite receivers to plot the location of vehicles.


o   G-Protect(SM) - a vehicle tracking function designed to prevent theft and
    loss. It also uses detailed electronic maps and global positioning satellite
    receivers to plot the location of stolen vehicles.

The Driver Logistics System 1000 Hardware includes:

o   The DriveStation(TM) - an in-vehicle device with a four-inch screen and
    ergonomically designed keys. Formerly called the Enhanced Mobile Workstation
    or "EMW", the DriveStation(TM) is designed to operate


                                       3

<PAGE>

    under all vehicle and road conditions using the Geotek SmartPort(TM), the
    gateway to the FHMA network. With the DriveStation(TM), drivers can receive
    job assignments, customer information, job status changes, routing and
    re-routing directions, and emergency assistance. They can also engage
    two-way text messaging, voice telephony, and digital radio communication.
    The DriveStation(TM) has two optional accessories that provide additional
    communication:

           - S.W.I.P.E.(TM) (Send. Write. Identify. Print. Exchange.), a Point
of Sale device that enables on-site credit transactions and provides printed
receipts; and

           - The Driver Logistics Portable which allows users to extend
information exchange beyond the vehicle by providing portable voice and text
communications capabilities.

o   The Driver Logistics(TM) WorkStation - is an IBM-personal computer, powered
    by an Intel 166 MHz Pentium microprocessor with 32 megabits of RAM. The
    WorkStation features a 15-inch color monitor, a high quality microphone, and
    built-in speakers housed in a mini-tower configuration.

Product Development

           Subject to the availability of financing, the Company, in the future,
plans to introduce additional products and services, including the Driver
Logistics System 2000 and System 3000 which are currently in the early stages of
development. The Driver LogisticsSystem 2000 is expected to feature more robust
software and advancements in the areas of safety/security, communications, and
task processing. In addition, the Company intends to introduce with its Driver
Logistics System 3000, a menu-driven, pad-sized screen device designed to
provide drivers with portability, an Internet interface, and a full portfolio of
hosted services.

Configuration of the Geotek Network Service Area

           The Company's FHMA Network employs a macrocellular architecture
consisting of a relatively small number of transmission sites with transmitters
capable of covering a radius of up to approximately 25 miles in diameter, the 

precise size depending upon geography and topography. The macrocells are
configured to form a digital wireless network in a given market. A base station
containing the central computer system and switching equipment is located at or
near one of the transmission sites in each market The system's use of a
relatively small number of sites and its ability to reuse frequencies enables
the Company to divide each cell coverage area into several sectors. In contrast,
many other wireless service providers, including conventional cellular system
and other enhanced specialized mobile radio ("ESMR") operators, build multiple
overlapping "cells," (multicell) sometimes dozens in a market, each with its own
low power transmission station. The Company believes its use of a relatively
small number of transmission sites enables it to reduce the infrastructure cost
required to service a market relative to the multicell approach employed by more
traditional wireless service providers. The Company also believes that its
system design allows it to initiate service in a given market at a lower cost
and achieve profitability with fewer customers than other digital wireless
communications providers. Further, the Company's ability to reuse frequencies
enables it to increase, at a relatively low cost, the capacity of its networks,
as such capacity is needed by further dividing a coverage area into sectors or
adding additional sites. The Company also believes that its networks will be
less expensive to operate than other multicell systems because, among other
things, the networks require less equipment, which results in lower costs for
transmission lines and site leases.

Technology

           The U.S. digital wireless network is based on the Company's
proprietary frequency hopping FHMA Network. The FHMA Network integrates Time
Division Multiple Access (TDMA), a standard digital transmission technique
currently utilized by digital cellular systems, with spatial sectorization,
frequency hopping, error correction coding and voice multiplexing. The Company
believes that the combination of

                                       4

<PAGE>

these techniques permits it to significantly increase the capacity of its radio
spectrum over that of traditional analog specialized mobile radio ("SMR")
capacity and improve the quality and security of wireless communications over
current analog systems.

The Network Roll-Out

           The Company is in the early stages of operations of its FHMA networks
in 11 metropolitan markets in the United States in Baltimore/Washington D.C.,
Boston, Dallas, Miami, New York, Orlando, Philadelphia, Tampa, Houston, San
Antonio and Phoenix. Subject to the availability of financing, the Company's
short-term business plan is to add customers and customer revenues and upgrade
the Driver Logistics System for sale in the 11 markets in which it is currently
operating. In accordance with its long-term business plans, subject to the
availability of additional financing, the Company intends to deploy its networks
in over 40 of the largest metropolitan markets throughout the United States in
which it currently owns licenses, on a regional basis. In the United States, the
Company controls 900 MHz frequencies with approximately 2,170 channels which the

Company believes should be sufficient to initiate digital wireless services in
all of the Company's targeted markets.

           The Company will be required to raise substantial financing, a
portion of which must be raised beginning in the second quarter of 1998, in
order to fund its ongoing working capital needs and to implement both its short
and long term business plans. (See Negative Cash Flow; Anticipated Future
Losses; Significant Future Capital Requirements; Need for Additional Cash;
Dilution, in Risk Factors below, as well as Footnote 1 to the Consolidated
Financial Statements.)

The Key Stages of the FHMA Network Roll-Out

The roll-out of the Company's FHMA Network in a particular market, the
pre-requisite to providing Driver Logistics Systems, consists of the following
key stages:

Propagation. Propagation analysis involves the identification, through software
programs and engineering analyses, of the optimal areas in a target market for
the placement of the base station and remote sites. The Company has
substantially completed its propagation analysis for the 11 U.S. target markets
in which it is currently operating.

Procurement of Site Leases and Permits. The Company must procure leases and
permits for the sites at which the digital wireless infrastructure base stations
and remote sites are to be located. The Company has engaged multiple site
leasing organizations to assist the Company in identifying potential site
leases, negotiating leases and acquiring required local approvals. The
acquisition of leases and required permits is typically a two-to-six-month
process, although delays may occur from time to time. As the Company increases
its coverage area in each of its target markets (including the markets where it
currently provides service), it will need to procure additional site leases.

Build-out. Preparation of each base station, which includes ventilation and air
conditioning, grounding and

                                       5

<PAGE>

equipment installation, testing and optimization, averages ten to twelve weeks.
As the Company adds customers and increases its coverage area in markets, it may
be required to increase the number of remote sites in such market.

Acquisition of Additional Spectrum and Transmission Sites. The Company may
require additional spectrum to add capacity and services in certain of its
existing markets as well as any future markets in the U.S. The Company
anticipates that it may eventually need more spectrum in its more populated
markets. As spectrum is a finite resource, there can be no assurance that the
Company will be able to obtain additional spectrum to meet its possible needs.
Additionally, the acquisition of additional spectrum may require significant
additional capital in certain of its more populated markets.

There are only a limited number of existing communications towers capable of

providing the Company with sufficient coverage for its radio transmissions and
supporting its transmission equipment. If the Company cannot obtain leases for
existing towers, it may be required to purchase sites, obtain necessary permits
and build such towers, which could take up to one year for each tower and
require additional financing. (See "Need for Additional Spectrum and
Transmission Sites" in Risk Factors below).

Integration Of New Services and Software. The Company's current and proposed
Driver Logistics Systems involve a complex integration of sophisticated voice
and data applications that utilize newly developed hardware and specialized
software products. The introduction of additional services requires testing and
hardware and software modifications in order to integrate such services with the
existing FHMA Network and Driver Logistics Systems. In addition, new software
may be required to solve technical difficulties that may arise in the operation
and performance of the FHMA Network and Driver Logistics Systems due to the
addition of customers, increased coverage area, and differences in geography and
topography in particular markets. (See "Integration of New Services and
Software" in Risk Factors below).

Marketing and Distribution

           The Company markets its Driver Logistics System both directly to
end-users and indirectly through a network of independent dealers and
distribution partners that have existing relationships with a large number of
its target customers. The Company utilizes dealers and agents that sell
communications systems solutions and services to business users. The Company's
strategy is to focus on acquiring and maintaining several dealer relationships
within each market. The Company supports its dealers in each local market with
Geotek employees that consist of indirect channel managers in the sales and
training area and technical support staff for installation and technical
information.

          The Company has initiated marketing activities with selected
distribution partners. These partners sell logistics solutions to business
customers and, in many cases, these customers want to extend these solutions to
their mobile workforce by means of a wireless communications system. For
example, the Company is pursuing an arrangement with IBM, whereby IBM and the
Company are jointly developing a solution to integrate existing legacy office
applications with wireless networks, which the Company believes can provide
additional value to both IBM's and the Company's customers.

          The Company intends to pursue further alliances, relationships, and
additional distribution agreements with data equipment, data services, and data
software companies. If consummated, the relationships could provide the Company
with access to both distribution capabilities as well as an established customer
base. The successful implementation of the Company's Driver Logistics Systems
and FHMA Network will depend, in part, on the Company's ability to develop,
maintain, and grow relationships with such parties. Delays in the implementation
of the wireless networks may adversely affect the Company's relationship with
its dealers, VARS, and distribution partners.

         In addition, the Company has increased its direct sales force to
augment the dealer network.


                                       6

<PAGE>

Increasing the size of the Company's sales force will result in substantial
additional expenses to the Company. The Company has no proven record of success
with marketing its products and services.

International Operations

Korea

           The Company holds a 21% interest in Anam Telecommunications, Inc.
("Anam Telecom"), a holder of a nationwide trunked radio system license in
Korea. The license covers a geographic area with a population of approximately
45 million people and is based on the implementation of the Company's FHMA
Network on an 800 MHz frequency. Anam Telecom commenced operations in November
1997 in the Seoul region of Korea.

           In 1997, the Company, through its subsidiary, Geotek Technologies,
Inc. ("GTI"), began delivering equipment and supervising the construction of
FHMA based digital networks under contracts with Anam Telecom, a related party,
and Hyundai Electronics Industries Co., Ltd. ("HEI"). HEI, in turn, sold such
equipment and services to unrelated Korean regional operators. The Korean
regional operators commenced operation in the fourth quarter of 1997. (See
"Risks of International Business" below.)

Canada

           In July 1997, the Company entered into a joint venture agreement with
two Canadian partners for the purpose of deploying FHMA Networks in the
provinces of Ontario, Quebec and British Columbia utilizing 900 MHz licenses
previously awarded to Geotek Communications Canada, Inc., a wholly owned
subsidiary of GeoNet Communications Canada, Inc. by Industry Canada, the
regulatory agency responsible for spectrum allocation in Canada. The Company's
joint venture partners withdrew from the joint venture in the first quarter of
1998. The Company has the option to reapply to Industry Canada for licenses at
such time that the Company obtains financing sufficient to pursue its business
in Canada.

Argentina

           The Company owns a 70% equity interest in Geotek Argentina S.A.,
which holds a nationwide trunked radio system license in Argentina. In August,
1997, Geotek Argentina S.A., was awarded 1 MHz frequency licenses in the 900 MHz
band covering metropolitan Buenos Aires, Cordova, Mendoza and Santa Fe, and is
currently in the process of deploying its demonstration site in Buenos Aires.

European Assets

           In December 1997, consistent with the Company's strategy to focus on
its U.S. operations and FHMA Networks, the Company entered into definitive
agreements to sell its European analog assets. In February 1998, the Company
completed the sale to Telesystems International Wireless, Inc. ("Telesystems")

of the Company's interest in its German joint venture ("Terrafon") and the
Company's wholly-owned subsidiary in the United Kingdom, National Band Three
Ltd. ("NB3").

           The Company sold all of the issued and outstanding shares of capital
stock of NB3, a wholly-owned subsidiary and provider of analog Private Mobile
Access Radio ("PAMR") service to approximately 64,900 business subscribers in
the United Kingdom, for approximately $82 million in cash. Five percent of the
$82 million purchase price is being held in escrow to satisfy the Company's
indemnity obligations, if any, under the agreement and will be released within
six months after the closing of the transaction, assuming no indemnity claims
are made. This transaction resulted in a gain to the Company of approximately,
$60.2 which will be recorded in the first quarter of 1998. At December 31, 1997,

million in cash, $3.2 million in accounts receivable, $5.2 million in goodwill
and $18.5 million in property, plant and equipment. The Company sold its
interest in Terrafon, the Company's 50/50 joint venture in Germany which was
formed through the merger of the Company's German networks with RWE Telliance
A.G. ("RWE") mobile radio network in December 1996 for DM 7,000,000
(approximately $3.9 million) in cash. DM 500,000 of the purchase price is being
held in escrow to satisfy the Company's indemnity obligations, if any, under the
agreement and will be released within fifteen months after the closing of the
transaction. Upon the decision to sell its investment in Terrafon, the
Corporation recognized a loss of approximately $12.9 million which was
recognized in the period ended December 31, 1997.

GMSI

          The Company owns an 80% interest in GMSI, Inc. ("GMSI"), a system
integrator for the transportation market which designs, manufactures, and sells
fleet management systems using mobile data software. GMSI is a leader in the
market for data dispatch systems used in large fleets for taxi, limousine,
paratransit, and public transportation. GMSI provides integrated solutions which
can operate on the Company's network. GMSI markets its products through a
combination of direct sales and value added resellers in North America, Asia,

enables the GMSI systems to work with a variety of wireless networks, in
addition to the Company's network, including SMR, private channel, and public
wireless data systems.

          The GMSI systems are integrated into the customers' office based
dispatch systems and host computer systems. In addition, GMSI provides a variety
of mobile data terminals, radio modems, installation services, and licenses,
third party software applications for use in fleet management.

Discontinued Operations - Communications Product Segment


           On November 26, 1997, the Company sold its communications products
subsidiary, Bogen Communications, Inc. ("BCI") for $18.5 million in cash. The
Company owned approximately 64% of the issued and outstanding capital stock of
BCI, which, in turn, owned 99% of Bogen Corporation ("Bogen") and 68% of Speech
Design GmbH ("Speech Design"). Bogen developed, produced and sold telephone and
telecommunications peripherals and sound and communications equipment through
its wholly-owned subsidiary, Bogen Communications, Inc. Speech Design, located
in Munich, Germany, developed, manufactured, and marketed telephone peripheral
hardware utilizing digital voice processing technologies. The Company has
presented the financial position and results of operations as discontinued
operations in the Company's Consolidated Financial Statements (See Footnote 2 to
the Company's consolidated financial statements).

Competition

           See discussion of "Competition" in Risk Factors, below.

Government and Industry Regulation

          The licensing, construction and operation of SMR systems in the United
States is regulated by the FCC under the Communications Act of 1934, as amended
(the "Communications Act"). The FCC currently regulates two types of 900 MHz SMR
licenses, both authorizing ten channels of 12.5 kHz in width from base station
to mobile. The Company holds both types. The first type is the Designated Filing
Areas ("DFA") licenses, which were issued by the FCC in the 1980's in 50 urban
markets, on a site-specific basis. The second type is the Major Trading Areas
("MTA") license, issued pursuant to the FCC's 900 MHz specialized mobile radio
("SMR") spectrum auctions, which were concluded in 1996. MTA licenses authorize
much larger

                                       8

<PAGE>

territories in 51 markets.

          At December 31, 1997, the Company held authorizations for 185 MTA
licenses and 98 DFA licenses. The MTA licenses are non-site-specific and have an
extended construction period of 3-5 years. Where the MTA licenses overlap
coverage with a DFA license, the MTA licensee must ensure non-interference
protection for the incumbent DFA licensee. Where the MTA licensee itself holds
the incumbent DFA license, the DFA license may be canceled or subsumed into the
MTA license, thereby assuming the regulatory/construction advantages of an MTA
license. In 1998, the Company has subsumed virtually all of its DFA licenses
that are surrounded by its MTA licenses, in order to take advantage of
regulatory/construction advantages. (See "Need for Additional Spectrum and
Transmission Sites.")

           Most of the equipment utilizing the Company's technology that is used
to send signals must satisfy certain technical standards and receive FCC type
acceptance approval. In addition, the Company's equipment and transmitter sites
must comply with the FCC's guidelines for human exposure to radio frequency
("RF") radiation. These guidelines apply to all MTA-based 900 MHz SMR licenses.

Although the Company's base stations and current subscriber units have received
such type acceptance approval from the FCC, there can be no assurance that
future generations of subscriber units or other equipment will meet such
standards.

           Under the Communications Act, SMR system providers were traditionally
regulated as private carriers and, therefore, were subject to less regulation by
both the FCC and individual states than were common carriers such as cellular
telephone companies. However, the FCC has initiated and is likely to continue to
initiate regulatory proceedings with wide-ranging implications for the wireless
telecommunications industry. Most of the rule-makings were initiated in response
to congressional amendments to the Communications Act, as directed by the
Omnibus Budget Reconciliation Act of 1993 (the "Budget Act"). The Budget Act
reconfigured the wireless marketplace to include a category of Commercial Mobile
Radio Service (CMRS) providers, which included all wireless carriers who offer
wireless services, interconnected to the public switched network to a
substantial portion of the public, for profit. In 1996, President Clinton signed
into law the Telecommunications Act of 1996 (the "Telecommunications Act") which
imposes sweeping reform of telecommunications policy. Although the majority of
the Telecommunications Act's measures directly impact large common carriers,
cable and broadcast operators, and Internet service providers, many of the
Telecommunications Act's provisions have an effect upon the wireless
marketplace, and upon the Company.

           Under the Budget Act and Regulations which have been promulgated
thereunder, the Company is now required to provide services on a
"non-discriminatory basis" and on terms that are not "unjust and unreasonable,"
as such terms are defined in the Communications Act. As a practical matter,
"non-discriminatory basis" means that the Company cannot tailor certain service
packages and price offerings to individual customers that are not generally
available to similarly situated parties. In addition, the Company must now limit
its foreign investors to 25% or less.

           The Company, like other common carriers, is now subject to various
state and federal programs designed to aid poor, rural, or disabled users of
telecommunications services. In particular, as a common carrier providing
interstate telecommunications services, the Company must comply with the FCC's
Universal Service program as well as the FCC's Telecommunications Relay Services
program. Both of these programs generally require the Company to contribute a
certain percentage of its interstate telecommunications revenues. In addition to
Federal requirements, many states have adopted, or will soon adopt, universal
service programs as well. States are permitted to require CMRS providers to
contribute in a non-discriminatory manner. The Company is also subject to the
requirements that it comply with the Commission's Equal Employment Opportunity
("EEO") rules and file annual reports concerning EEO complaints. Finally, the
Company is required to pay annual regulatory fees to the Commission based upon
the number of subscribers.

           Under past proceedings, the FCC determined that Local Exchange
Carriers ("LECs") must offer

                                       9

<PAGE>


interconnection to CMRS providers on reasonable terms and conditions, and under
the principle of mutual compensation. The FCC declined to impose direct
interconnection obligations for CMRS-to-CMRS transmissions. Although it is not
yet final, the FCC may enforce specific limits with respect to prices, terms,
and conditions of interconnection arrangements for LEC-CMRS interconnection, to
ensure that CMRS providers are granted equal competitive footing with more
established LEC service providers. While the 8th Circuit Court of Appeals
vacated much of the FCC's local competition rules and policies dealing with
interconnection to LEC networks in July 1997, it generally left intact those
policies governing LEC-CMRS interconnection. In addition, on December 30, 1997,
the FCC's Common Carrier Bureau issued a formal letter ruling, declaring that
LECs may not charge CMRS providers for LEC-originated traffic that terminates on
CMRS networks. This letter confirmed prior FCC rule-making policy and may be
further challenged by LECs.

           In a separate proceeding, the FCC amended its rules to permit
broadband and narrowband CMRS providers to offer wireless local loop and related
services. Specifically, the FCC adopted a definition of "wireless local loop"
that is sufficiently broad to allow the provision, by CMRS providers such as the
Company, of certain fixed services. The definition of "wireless local loop" is
"the path between the subscriber and the first point of switching or aggregation
of traffic." Such an expansion in available service offerings could be
beneficial to the Company.

           In late 1997, the FCC completed its proceeding designed to ensure the
availability of 911 and enhanced 911 (or "E911") services for users of mobile
telephones. The FCC's decision generally requires covered providers (as well as
other mobile telephone providers) to transmit all 911 calls to Public Safety
Answering Points ("PSAPs") , including calls made by non-subscribers. In
compliance with FCC rules, the Company will satisfy its 911 responsibilities
through the use of a trained dispatcher.

           If digital calling technology is employed by the Company in a
particular market, it must generally transmit 911 calls made using text
telephone devices ("TTY's'), used by the hearing-impaired, by no later than
October 1, 1998 (analog service providers must already provide TTY access to
911). With regard to the FCC's E911 requirements, by April 1998, the Company is
required to transmit certain caller data to the PSAP as well as the cell site of
the caller. Finally, by October 2001, the Company's systems must be capable of
notifying the PSAP of the approximate geographic location of the caller. These
last two E911 requirements only become effective if the local or state 911
system has adopted a cost recovery mechanism and has requested these enhanced
services from the wireless provider.

           In its docket No. 94-54 proceeding, the FCC adopted several
operational requirements for CMRS providers, including the requirement that
"covered SMR" providers offer "manual" roaming. The FCC is currently seeking
comment on whether it should require "automatic" (carrier-to-carrier) roaming as
well. In this same proceeding, the FCC already concluded that covered SMR
providers must allow the unrestricted resale of their services. Because the
Docket No. 94-54 proceeding's definition of covered SMR provider includes those
900 MHz SMR providers holding MTA licenses, the Company is required to comply
with the agency's resale and roaming policies. For the same reason, the Company

is subject to the FCC's "number portability" requirements adopted in Docket
95-116. Several industry trade associations have sought to delay or eliminate
the FCC's number portability requirements for certain CMRS providers, including
covered SMR providers. The applicability of these four proceedings -- "E911",
"roaming", "resale", and "number portability" - to the Company depends upon the
FCC's definition of "covered SMR" and whether the Company falls within that
definition. The FCC's determination in these proceedings remains subject to
further revision.

Other Regulatory Matters

           In 1996, the President signed into law the Communications Assistance
for Law Enforcement Act ("CALEA") which requires communications carriers to
allow law enforcement the ability to "monitor" calls on their wireless systems.
CALEA requires compliance with Federal Bureau of Investigation Assistance

                                     10

<PAGE>

Capability Requirements within four years of the signing of CALEA into law. On
October 10, 1997, the FCC commenced a rule making proceeding, soliciting comment
on which types of communications providers should be subject to CALEA. The FCC
tentatively concluded that carriers offering services similar to those offered
by the Company should be covered by CALEA. However, this proposal is subject to
revision through the agency's rule making process as well as the actions of the
FBI. Although it is not yet certain, it is likely that the Company, along with
other SMR operators, may be waived from complying with CALEA.

Patents and Technology Rights

           GTI-Israel, in its own name and jointly with the Company, has filed
several patent applications in Israel and in other countries, including the
United States. In addition, GTI-Israel has an exclusive royalty free right to
utilize the technology covered by U.S. patents issued to Rafael.

           In addition to those patent applications filed by GTI-Israel, the
Company also has filed patent applications in Israel, the United States and
other countries based on technology developed by the Company. In August, 1997,
the Company was granted a design patent in the United States for a mobile
communications terminal. As of December 31, 1997, no Israeli patents have been
issued to the Company or GTI-Israel and there can be no assurance that a patent
will be issued from any pending or future patent applications or that if any are
issued that any of them will have any commercial significance. The Company is
aware of certain patents and patent applications held or filed by others which
generally relate to the subject matter of the Company's activities. The Company
believes that none of such patents or applications is likely to have a material
adverse effect on the ability of the Company to utilize any technology currently
intended to be utilized by the Company.

           The Company owns several trademarks, including Geotek(R) and FHMA, in
the United States and certain other countries. Where other applications have
been filed, registrations are still pending.


           The Company's engineering and development expense related to the
digital wireless communication system totaled $39.6 million in 1997 compared to
$34.0 million in 1996 and $33.0 million in 1995.

Employees

           As of December 31, 1997, the Company had approximately 685 full-time
employees engaged in its wireless communications businesses. The Company
considers its relationship with its employees to be good.

           As of December 31, 1997, subcontractors, including Rafael, were
engaged in the production, development and enhancement of the Company's FHMA
Network. Rafael's employees are represented by a labor union, and, from time to
time, there have been labor disputes between Rafael and its employees. To date,
these slow-downs have not had a material effect on the Company's business. There
can be no assurance, however, that any future disputes will not adversely affect
Rafael's ability to deliver equipment to the Company, which could further delay
the future technical development and enhancements to the Driver Logistics
System.

RISK FACTORS

Negative Cash Flow; Anticipated Future Losses; Significant Future Capital
Requirements; Need For Additional Cash; Dilution

           The Company has never been profitable, has never generated positive
cash flow from consolidated operations and, since its inception, has incurred
significant net operating losses and negative cash flow. The Company had
consolidated net losses from continuing operations of $225.7 million, $140.3
million and $83.1 million for the years ended December 31, 1997, 1996 and 1995,
respectively. In addition, the Company had a

                                       11


<PAGE>

deficiency of earnings before interest, taxes, depreciation and amortization
("EBITDA") of $161.5 million, $96.6 million and $62.4 million for such periods,
respectively. The Company anticipates that its net losses from operations and
its EBITDA deficiency will continue during the commercialization and continued
development of the Driver Logistics System and the implementation of the FHMA
Network. There can be no assurance that the Company's Driver Logistics System
and FHMA Network will ever provide a revenue base adequate to achieve or sustain
profitability or generate positive cash flow.

           The Company will be required to raise substantial financing, a
portion of which must be raised beginning in the second quarter of 1998, in 
order to continue to fund its ongoing working capital needs and to implement 
its business plan. The Company's short-term business plan is to increase the 
number of customers and customer revenues and to offer new services in the 11 
markets in which it is currently operating, and its long-term business plan is 
to roll-out the Driver Logistics System utilizing the FHMA network in over 40 
markets and to enhance its network operations and to take advantage of 
international

opportunities. The Company estimates that through the end of 1998, approximately
$85 million will be required in order to fund working capital needs and debt
service, affecting the Company's ability to significantly increase the number of
customers subscribing to the Driver Logistics System in the 11 markets in which
it is currently operating. At December 31, 1997, the Company had approximately
$13.4 million of cash and cash equivalents and a $89.6 million vendor credit
facility available, the last $50 million of which is subject to satisfaction of
certain conditions and can only be used for the purchase of infrastructure
equipment from Hughes Network Systems, Inc. The $13.4 million in cash and cash
equivalent may be used for working capital and general corporate purposes. In
addition, the Company had $9.1 million in restricted cash from the sale of BCI,
which was released in the first quarter of 1998, and in February 1998, upon
completion of the sale of its European analog networks, received an additional
$85 million in restricted cash. In accordance with amendments under the
indenture governing its Senior Secured Discount Notes due 2005 ("15% Discount
Notes"), the Company can use the proceeds from the sale of European assets as
follows: 40% for qualifying capital expenditures; 40% for working capital; and
20% for the repayment of the pro rata portion of the accreted value of the
Discount Notes. The Company does not intend to construct additional U.S. markets
until such time as it obtains sufficient financing to do so. In addition, the
Company does not intend to expand existing or to deploy new international FHMA
networks until additional capital is obtained. Further, the Company may require
financing for certain of its debt obligations, including potential redemption
obligations with respect to certain series of the Company's preferred stock.
(See "Substantial Leverage; Future Repayment Obligations.")

           To meet its additional capital requirements and to successfully
implement its strategy, the Company plans to seek additional financing, to the
extent available, from one or more sources, including, but not limited to,
public or private equity or debt financing, bank loans, strategic partners,
joint ventures, vendor financing, leasing arrangements, asset sales or a
combination of these sources. The Company has obtained the consent of a majority
of the holders of certain of the Company's debt securities to utilize up to
approximately $40 million of the proceeds from debt financings and/or additional
asset sales for working capital purposes. There can be no assurance that the
Company will be able to obtain the additional financing, in a timely manner,
necessary to satisfy its cash requirements or to implement its strategy
successfully. The failure to obtain the requisite additional capital in the
short term, fiscal 1998, would prevent the Company from executing its short and
long-term business plan, would result in the Company violating certain debt and
contractual covenants, and would raise substantial doubts about the Company's
ability to continue as a going concern.

           The issuance of additional equity securities or securities
convertible into equity securities, in addition to the possible conversion of
existing convertible preferred stock, and convertible notes, the redemption of
redeemable preferred stock, the exercise of warrants and options or the possible
repayment of other similar obligations in Company stock, will result in the
dilution of the Company's stockholders. Further, under the applicable conversion
formulae for certain series of Preferred Stock, the number of shares of Common
Stock issuable upon conversion will increase if the market price of the Common
Stock decreases. Moreover, the Company cannot determine accurately the number of
dividend shares which may be issued to the holders of the Company's Series N
through Series S Convertible Preferred Stock, as such number is based upon the


                                       12

<PAGE>

market price of the Common Stock prior to the payment of such dividend.

Substantial Leverage; Future Repayment Obligations

           As of December 31, 1997, the Company's consolidated long-term debt,
including current portion and redeemable preferred stock, was approximately
$326.1 million. During 1997, the Company's annual cash payments for debt service
and preferred stock dividends were $18.2 million and will increase to
approximately $20 million in 1998 and to at least $55.0 million beginning in
2001. The Company's obligations to pay principal on its currently outstanding
indebtedness will commence in October 1998 (except that the Company is required
to use 20% of the proceeds from the sale of NB3 and Terrafon to make a tender
offer to the holders of the Company's 15% Senior Secured Discount Notes due 2005
(the "15% Discount Notes"), on a pro rata basis according to the accreted value
of the 15% Discount Notes, within 30 days after the consummation of such sales)
when principal and interest payments on indebtedness to Hughes Network Systems
in the original principal amount of $24.5 million will become due and payable to
the extent this indebtedness has not then been converted into Common Stock or
renegotiated by the Company.

           Interest payments on borrowings under the Company's vendor financing
agreement with HNS are semi-annual and will commence on July 15, 1999 (unless an
event of default occurs earlier), and principal payments will commence in 1999.
The Company's obligations will increase significantly starting in 2001, when
interest payments will commence on the 15% Discount Notes and the principal
amount of any of the Company's 12% Senior Subordinated Convertible Notes due
2001 (the "12% Notes") then outstanding will become due and payable. The Company
also is required to repay $40 million in November 2002 pursuant to a Senior Loan
Facility (the "Senior Loan Facility") to entities affiliated with S-C Rig (as
defined below). In October 2000, the Company's Series H Cumulative Redeemable
Convertible Preferred Stock ("Series H Preferred Stock") is redeemable at the
option of the holders for an aggregate price of $40 million. The Company may
elect to pay the redemption price in shares of Common Stock having an aggregate
market value equal to 150% of the redemption value of the Series H Preferred
Stock being redeemed. If the Company's cash flow from operations is insufficient
to make such payments, the Company would be required to refinance or renogotiate
the terms of some or all of such indebtedness in order to avoid a default. There
can be no assurance that the Company would be able to refinance such
indebtedness on acceptable terms or in a timely manner. A default under the 15%
Discount Notes or the 12% Notes would have a material adverse effect on the
Company's financial position (see Footnote 1 to the Company's consolidated
financial statements).

           The Company's substantial indebtedness may have important adverse
consequences, including (i) impairment of the Company's ability to obtain
additional financing in the future for working capital, capital expenditures and
general corporate purposes; (ii) direction of a substantial portion of the
Company's cash flow from operations to the payment of principal and interest,
reducing funds available for other purposes, including the successful and timely

development and marketing of the Driver Logistics System, (iii) the Company
becoming more highly leveraged than other competing companies; and (iv) an
increased vulnerability to a downturn in its business or the economy in general.
In addition, the instruments governing the Company's outstanding indebtedness
impose significant operating and financial restrictions, which limit, among
other things, the Company's ability to incur indebtedness, utilize proceeds of
debt financings and/or asset sales for working capital purposes, repay new
indebtedness, pay dividends, make investments, engage in transactions with
stockholders and affiliates, issue capital stock of its subsidiaries, create
liens, sell assets and engage in mergers and acquisitions. Although these
instruments contain exceptions to these restrictions that are designed to allow
the Company to operate its business without undue restraint, such restrictions,
together with the Company's high degree of leverage, could limit its ability to
effect future financings and respond to changing market conditions.

                                       13

Dependence Upon Commercial Implementation of the Driver Logistics System and
FHMA Network

           The Company's success will depend to a significant extent on its
ability to successfully market its Driver Logistics System in its target United
States markets. The successful and timely commercialization of the Driver
Logistics System will depend on various factors, many of which are beyond the
Company's control. These factors include, among others, the timely and
cost-effective manufacture, construction, testing, and integration of the FHMA
network infrastructure and software sufficient to provide adequate coverage,
stability, and capacity, the procurement and preparation of base station and
remote sites, the receipt of necessary regulatory approvals, the availability of
substantial additional financing in the short term and long term, recruitment
and successful training of the Company's sales staff and dealer network,
increasing competition, and market acceptance of the Driver Logistics System.

Dependence Upon Integration of New Services and Software

           The Company's current and proposed services involve a complex
integration of sophisticated voice and data applications that utilize newly
developed hardware and specialized software products. The development and
implementation of the Driver Logistics System and FHMA Network to date has
raised and continue to raise technical difficulties, which have and may
continue to adversely affect service to customers in certain markets. Additional
technical difficulties may arise from time to time as the Company continues to
make hardware and software modifications, add new services and increase the
number of customers in a particular market. The introduction of additional
services is expected to require testing and hardware and software modifications
in order to integrate such services with the existing services, which may
present technical problems. During the fourth quarter of 1997, the Company began
introducing new operating system software in its current U.S. markets.
Integration of such software required significant modification to the network
and the hardware utilized by the Company's customers, as well as testing. The
success and timing of the integration of new services and new software and/or
the negative impact, if any, to the Company's customers from an interruption of

service cannot be predicted. In addition, new software may be required to solve
technical difficulties that may arise in the operation and performance of the
Driver Logistics System and FHMA Network as additional subscribers are added in
a particular market or as the coverage area in any market is increased.
Furthermore, each of the Company's U.S. target markets could present unique
technical issues due to differences in geography and topography, which may also
require new software. Delays in the integration of new services and new
software, or an adverse reaction from the Company's customers, could have a
material adverse effect on the Company's ability to successfully market the
Driver Logistics System, and accordingly upon other financial results, such as
revenues, cash flow and results of operations.

Dependence On Customer Receipts; Need to Lower Cost of Manufacturing Customer
Equipment

           To date, the Company's operating expenditures incurred with respect
to its existing and planned offerings in each of its commercial markets have
significantly exceeded customer receipts. The Company attributes this
performance to two factors. Currently, customer equipment is provided to
customers for substantially less than the cost to manufacture such equipment.
Second, as a result of the Company's early promotional efforts and technical
difficulties, the Company has no significant amounts of anticipated revenue from
its U.S. customers. The Company's goal is to decrease such losses as it
continues to add customers and eliminate technical difficulties. Additionally,
the Company hopes to be able to lower the manufacturing cost of customer
equipment as customer volume increases and additional vendors manufacture the
units. However, there can be no assurance regarding the amount, if any, that the
Company's customers will pay for the Driver Logistics System or for service or
that the Company will be able to reduce the manufacturing cost of customer
equipment sufficiently to make manufacturing cost-effective; nor can there be
any assurance that the Company will be able to improve its collection of
revenues. More generally, there can be no assurance that the Driver Logistics
System will achieve market acceptance in the Company's targeted markets. The
inability of the Company to increase the price paid by customers, reduce
sufficiently its costs for its equipment, or establish an adequate customer base
in each of its markets could have a material adverse effect on the

                                       14

<PAGE>

Company's cash flow from operations and financial position and the Company's
ability to compete in the marketplace (see Footnote 1 to the Company's
consolidated financial statements for discussion on impairment of long-lived
assets).

Dependence Upon The Driver Logistics  Portable.

           The Company recently introduced the Driver Logistics(TM) Portable
(the "Portable"). This may create additional technical challenges specific to
those customers using the Portable, including being able to provide a
commercially acceptable level of system coverage to those customers. In order to
provide proper network support for the Portable, the Company may be required to
construct additional sectors and acquire additional frequencies, which could

materially impact cost structure. The Company's ability to successfully
integrate the Portable and the costs required for such integration cannot be
accurately determined until the completion of additional analysis and testing.
The Company's inability to adequately integrate the Portable into its network or
to successfully market the Portable to its customers could adversely affect the
Company's ability to successfully market the Driver Logistics Portable.

Limited Operating History

           The Company has limited experience in marketing Driver Logistics
Systems and in developing, establishing and operating wireless communications
networks. Further, a significant portion of the Company's operating experience
to date has occurred in foreign markets, primarily the United Kingdom and has
involved technology different from the Company's proprietary technology. The
Company's experience to date in the United States has been limited to providing
primarily voice and data dispatch services during 1996 to a relatively few
number of customers in seven of its 11 current markets. During 1997, the Company
provided voice and data services in eleven markets. Therefore, there is limited
historical financial and operating information to evaluate the Company's ability
to operate successfully as a provider of integrated digital voice and data
wireless communications services.

Need to Manage Growth; Dependence On Key Personnel

           Successful development and marketing of the Driver Logistics System
in the Company's target markets will require expansion of the Company's
operating, financial and management systems, which, in turn, will require
additional senior management and a substantial number of additional technical
and sales personnel. The Company's success will depend in part on its ability to
attract, retain, motivate, train and manage additional individuals as well as
existing personnel. The substantial growth in the wireless communications
industry in recent years has created a strong need for talented and experienced
individuals and, accordingly, the market for such individuals is very
competitive. There can be no assurance that the Company will be able to attract
and retain such individuals necessary to support the proposed expansion of its
operations.

           The success of the Company will depend greatly upon the experience
and active participation of its management. The Company has entered into
employment agreements with certain members of senior management, including those
employees who oversee the operations of the Company's main operating units. The
loss of members of its senior management could adversely affect the Company's
business. In addition, the successful further development and successful
marketing of the Driver Logistics System will depend, to a large extent, upon
the ability of the Company's engineers and scientific technical personnel to
perfect and improve existing and proposed products. The loss of some or all of
such personnel, the inability of the Company to attract additional personnel, or
the inability of such persons to design products or to continue product
enhancement in response to subscribers' demands or competitive pressures would
inhibit the Company's ability to sell its products and services and to operate
profitably.

Need for Additional Spectrum and Transmission Sites

           The Company may require additional spectrum to add capacity and
services in certain of its existing markets as well as any future markets in the
U.S. The Company anticipates that it may eventually need more spectrum in
certain of its more populated markets. Because spectrum is a finite resource,
there can be no assurance that the Company will be able to obtain additional
spectrum to meet its possible needs. Additionally, acquisition of additional
spectrum may require significant capital resources. The inability of the Company
to obtain additional spectrum that it may require could limit its ability to
expand its services and to increase the number of customers able to utilize the
Company's proprietary FHMA digital wireless network and Driver Logistics Systems
in certain markets.

           There are only a limited number of existing communications towers
capable of providing the Company with sufficient coverage for its radio
transmissions and supporting its transmission equipment. If the Company cannot
obtain leases for existing towers, it may be required to purchase sites, obtain
necessary permits and build such towers, which could take up to one year for
each tower. If the Company is required to build new towers, the implementation
of the FHMA network Driver Logistics System in one or more of its target U.S.
markets could be delayed.

Impact of Government Regulation

           The licensing, construction and operation of SMR systems in the
United States is regulated by the FCC under the Communications Act of 1934, as
amended (the "Communications Act"). The FCC currently regulates two types of 900
MHz SMR licenses, both authorizing ten channels of 12.5 KHz in width from base
station to mobile. The Company holds both types. The first type is the
Designated Filing Areas ("DFAs") licenses, which were issued by the FCC in the
1980's in 50 urban markets, on a site-specific basis. The second type is the
Major Trading Areas ("MTA") license, issued pursuant to the FCC's 900 MHz
specialized mobile radio ("SMR") spectrum auctions, which were concluded in
1996. MTA licenses authorize much larger territories in 51 markets. At December
31, 1997, the Company held authorizations for 185 MTA and 98 DFA licenses. The
MTA licenses are non-site-specific and have an extended construction period of
3-5 years. Where the MTA licenses overlap coverage with a DFA license, the MTA
licensee must ensure non-interference protection for the incumbent DFA licensee.
Where the MTA licensee itself holds the incumbent DFA license, the DFA license
may be canceled or subsumed into the MTA license, thereby assuming the
regulatory/construction advantages of an MTA license. The Company has subsumed
virtually all of its DFA licenses that are surrounded by its MTA licenses, in
order to take advantage of regulatory/construction advantages. (See "Need for
Additional Spectrum and Transmission Sites.")

           In accordance with the Indenture (the "Indenture") governing the 15%
Discount Notes, the Company pledged an interest in certain of its subsidiaries
that hold a majority of the Company's DFA Licenses. In addition, on December 21,
1995, the Company, through its subsidiaries, entered into the Loan Agreement and
on September 27, 1996 entered into a Vendor Credit Financing Agreement (the
"Credit Agreement") with HNS pursuant to which the assets of the Company's

subsidiary, Geotek License Holdings, Inc., consisting of all MTA licenses
obtained by the Company during 900 MHz SMR spectrum auctions were pledged to HNS
as security. In December 1997, the trustee under the Indenture and HNS agreed to
reallocate the MTA licenses among subsidiaries of the Company all of whose stock
is pledged either to the Indenture trustee or to HNS.

           As permitted by the FCC, the Company subsumed its Designated
Frequency Area ("DFA") licenses which were acquired prior to the 1996 auctions
with the Company's MTA licenses so that, together, they are regulated as a
single MTA license. Under the terms of the MTA licenses the Company acquired
during the auctions, a MTA will be "constructed" if one-third of the market's
population is served within three years of the grant, August 12,

                                       16

<PAGE>

1999, and two-thirds of the population are served within five years of the 
grant, August 12, 2001. As an alternative, the Company may elect for the FCC to
waive the requirements for August 12, 1999 and agree that the construction
requirements, that the Company provide substantial service to the MTA, be met by
August 12, 2001. At December 31, 1997, approximately $39.4 million (cost basis) 
of the Company's $72.7 million of licenses were being utilized for commercial
service.

           Most of the equipment utilizing the Company's technology that is used
to send signals must satisfy certain technical standards and receive FCC type
acceptance approval. In addition, the Company's equipment and transmitter sites
must comply with the FCC's guidelines for human exposure to radio frequency
("RF") radiation. These guidelines apply to all MTA-based 900 MHz SMR licenses.
Although the Company's base stations and current customer equipment have
received such type acceptance approval from the FCC, there can be no assurance
that future generations of customer units or other equipment will meet such
standards.

Dependence Upon Third Party Providers

           The Company is dependent upon a relatively small number of
manufacturers for its products. Rafael Armament Development Authority
("Rafael"), a related party and a division of the Israeli Ministry of Defense,
is subcontracted for manufacturing and enhancing the base station and remote
sites. The terms of the Company's license of FHMA technology from Rafael and the
Company's receipt of certain capital grants provided by the State of Israel
impose limitations on the Company's ability to transfer the manufacture and
enhancement of certain aspects of its FHMA infrastructure absent the approval of
Rafael and the State of Israel.

           Rafael has developed the base station equipment. In September 1996,
the Company and a wholly-owned subsidiary of the Company, Geotek Financing
Corporation ("GFC"), entered into an agreement with HNS pursuant to which HNS
agreed to manufacture certain of the components required for the construction of
900 MHz FHMA base station equipment in order to expand the Company's
manufacturing supply sources. In addition, HNS is providing up to $100 million
of financing (the last $50.0 million of which is subject to the satisfaction by

the Company of certain operating criteria) for up to 90% of the purchase price
of equipment scheduled for delivery by HNS to the Company prior to June 30,
1999. As of December 31, 1997, the Company has drawn down $10.4 million of the
$100 million. Rafael and HNS are currently producing base station equipment for
the Company's U.S. wireless network.

           The Company procures all other components utilized in connection with
its digital wireless system from third parties. Farbell Electronics manufactures
large and small screen vehicle-mounted customer units and HNS manufactures the
portable unit. In 1997, Mitsubishi Consumer Electronics of America ("MCEA")
manufactured the mobile car radio, but will no longer do so. The Company does
not believe this will have a material impact on the Company's business because
going forward, the mobile car radio will be manufactured by GTI-Israel, a
subsidiary of the Company. In June 1997, the Company also entered into a
development and purchasing agreement with IBM to develop and produce an enhanced
telephone and dispatch switch, in order to upgrade its existing switches for
high customer capacity.

           There can be no assurance that such third parties will deliver such
equipment on a timely basis. Although the Company believes that it can obtain
all components necessary to build the digital wireless system from other
sources, it may encounter delays in the event of a component shortage due to the
time needed to identify alternative sources and manufacture substitute
components. With the exception of Rafael and HNS, none of the Company's
suppliers has previously manufactured FHMA system equipment. Failure to obtain
hardware components on a timely basis or at satisfactory prices could result in
delays or cost overruns in the implementation of the U.S. network and Driver
Logistics System.

           The Company has agreements with several parties, including IBM to
manage the construction of the U.S. wireless network base station and remote
sector sites. The Company also has engaged, and intends to engage, other third
party contractors to manage all or certain aspects of such construction or
installation in certain of its U.S. target markets. A failure such
contractors to manage properly the

                                       17

<PAGE>

preparation and construction of the Company's base station and remote sector
sites could delay the enhancement and continued roll-out of the FHMA Network,
thereby jeopardizing the Company's FCC licenses and general adversely affect the
Company's business.

Risks of International Business

           Certain of the Company's products and components are manufactured
outside of the U.S. and its engineering and development activities are dependent
upon foreign providers. (See "Dependence on Third Party Providers.") Further,
the Company currently sells its products and services in various countries and
may pursue opportunities in other countries. Accordingly, the Company is
subject, but not limited, to the risks inherent in conducting business across
international boundaries, including currency exchange rate fluctuations,

international incidents, military outbreaks, economic downturns, government
instability, nationalization of foreign assets, government protectionism and
changes in governmental policy, any of which could adversely affect the
Company's business in one or more of its international markets or in the U.S.
For instance, the November devaluation of the Korean Won may have an adverse
impact on the Company's investments in Korea, the Company's ability to collect
receivables in dollars, or the Company's ability to successfully market its
products in that country in the future.

           The Company and entities in which the Company has an interest
currently hold licenses to operate communication networks in Korea and
Argentina. The licensing and other operational risks attendant upon commencing
and maintaining wireless communications networks in foreign countries are
similar to those in the U.S., including availability of spectrum capacity and
transmission sites, competition and government regulation.

           In July 1997, the Company entered into a joint venture agreement with
two Canadian partners for the purpose of deploying FHMA Networks in the
provinces of Ontario, Quebec and British Columbia utilizing 900 MHz licenses
previously awarded to Geotek Communications Canada, Inc., a wholly owned
subsidiary of Geotek Communications Canada, Inc. by Industry Canada, the
regulatory agency responsible for spectrum allocation in Canada.

           The Company's joint venture partners withdrew from the joint venture
in the first quarter of 1998. The Company has the option to reapply to Industry
Canada for licenses at such time that the Company obtains financing sufficient
to pursue its business in Canada.

         In Korea, the network is based upon the implementation of the FHMA
Network on the 800 MHz frequency. There can be no assurance that the Company
will be able to successfully adapt and market its FHMA Network to another
frequency or standard on a timely or cost-effective basis, if at all. Further,
the roll-out of products and services in each of these countries will be subject
to the same risks attendant to the marketing and development of the Company's
Driver Logistics System and FHMA Network in the U.S. Moreover, certain foreign
regulatory authorities may limit the Company's ownership interest in licenses or
the operating entity which it owns and operates under such licenses. There can
be no assurance that the Company will be successful in developing its business
in any of these markets.

         Certain international regulations may limit the Company's interest in
entities that hold licenses or operate wireless networks in various countries.
Thus, the Company's ability to expand its interest in international markets may
be limited.

Year 2000 Issues

           The Company's software and hardware were developed relatively
recently and, therefore, do not require any significant modifications for the
Year 2000. However, the Company may face Year 2000 issues as it seeks to
coordinate with other entities with which it interacts electronically, including
suppliers, customers and

                                       18


<PAGE>

distribution partners. Although the Company is not currently aware of any
material problems, an assessment has not been made of the anticipated costs,
problems and uncertainties associated with the Year 2000 consequences.

Competition

           Competition in the logistic wireless communications industry is
intense and is expected to increase. The Company faces significant competition
in each of the U.S. markets that it currently serves and expects to face
significant competition in its planned United States markets as well. The
Company competes with established, new and planned SMR, cellular, paging,
satellite, personal communications services ("PCS") and public data service
providers. In addition, the Company competes with manufacturers of PMR
equipment, which target private network operators and SMR customers. Many of the
Company's competitors have substantially greater technical, marketing, sales and
distribution resources, access to capital, and experience providing wireless
communications services than the Company.

           The Company competes for subscribers primarily on the basis of
services offered, the technical quality of its system, capacity, coverage and
price. Many of the target customers for the Company currently use other wireless
communications services. In order to compete effectively, the Company must
attract a portion of its target customers from their existing providers. The
Company's marketing strategy emphasizes its integrated package of voice and data
services, which the Company believes differentiates it from other wireless
communications providers. However, there can be no assurance that potential
customers will perceive the Company's services to be superior to those offered
by other wireless communications providers.

Risk of Rapid Technology Changes

           The telecommunications industry is subject to rapid and significant
technological changes, which could result in new product and/or service
offerings. The Company believes that such new offerings could compete directly
with those currently offered by the Company or could lower the cost of currently
competing offerings such that the Company would be required to reduce the prices
for its offerings. Any such reduction would ultimately affect the Company's cash
flow from operations. While the Company is unaware of any proposed changes that
are expected to materially diminish the attractiveness of its products and
services, the nature or timing of technological changes or the effect of such
changes on the Company's business cannot be predicted. In the future, the
Company expects to encounter competition from new technologies, including but
not limited to ESMR networks, PCS and possibly satellite technology, as well as
from advances in existing technologies such as cellular, paging and mobile data
transmission. (See "Competition" above).

Proprietary Information and Patent Issues.

           The Company protects its proprietary information by way of
confidentiality and non-disclosure agreements with employees and third parties
who may have access to such information. The Company continually reviews its

technology developments in order to file patent applications and has filed
patent applications with respect to certain aspects of its FHMA technology in
Israel, the U.S. and other countries and expects to file additional patent
applications in Israel and the U.S. Generally, the Company intends to file all
patent applications in the United States and Israel and in such other countries
as it deems appropriate. There can be no assurance that such applications will
be granted. There can be no assurance that any patents issued will afford
meaningful protection against competitors with similar technology or that any
patents issued will not be challenged by third parties. There also can be no
assurance that others will not independently develop similar technologies,
duplicate the Company's technologies or design around the patented aspects of
any technologies developed by the Company. Many patents and patent applications
have been filed by third parties with respect to wireless communications
technology. The Company does not believe that its technology infringes on the
patent rights of third parties. However, there can be no assurance that certain
aspects of the Company's technology will not be challenged by the holders of
such patents or that

                                       19

<PAGE>

the Company will not be required to obtain a license from or otherwise acquire
from third parties the right to use certain technology. The failure to overcome
such challenges or obtain such licenses or rights could have a material adverse
effect on the Company's operations.

Influence by Significant Stockholders; Preemptive Rights

           As of December 31, 1997, approximately 36.2% of the total voting
power of the Common Stock (on a fully-diluted basis) was beneficially owned by
the directors and executive officers of the Company and their affiliates.
Consequently, the Company's directors and executive officers will be able to
exert significant influence with respect to all matters upon which stockholder
approval is required.

           Pursuant to certain agreements among them, certain of the principal
stockholders of the Company have the right to require certain other stockholders
to cause (to the extent permitted by law and to the extent within such other
stockholders' control) the directors of the Company to vote, or refrain from
voting, in accordance with such stockholders' direction with respect to the
election of directors. In addition, S-C Rig Investments-III, L.P. ("S-C Rig")
and Vanguard Cellular Systems, Inc. have preemptive rights with respect to
certain issuances of voting securities by the Company which permit them to
purchase voting securities of the Company, at the same price and on the same
terms as the Company may offer to third parties, in an amount sufficient to
maintain their respective percentage interests in the voting securities of the
Company on a fully-diluted basis. The Company also has granted to the holders of
the Series H Preferred Stock, Series I Cumulative Convertible Preferred Stock,
Series K Cumulative Convertible Preferred Stock and Series N Cumulative
Convertible Preferred Stock the right to elect additional directors to the Board
of Directors of the Company upon the occurrence of certain events of default.
The operation of such provisions could result in such stockholders exerting
significant influence over the Board of Directors of the Company.


Shares of Common Stock Reserved for Issuance; Shares of Common Stock Eligible
for Sale

           As of December 31, 1997, the Company had an aggregate of
approximately 73.6 million issued and outstanding shares of Common Stock. In
addition as of such date, the Company had reserved for issuance an aggregate of
approximately 124.9 million shares of Common Stock issuable pursuant to (i)
outstanding vested and non-vested options, warrants and similar rights; (ii)
conversion of other outstanding convertible securities of the Company (including
shares issuable upon conversion of the Company's preferred stock); (iii)
dividends on the Company's preferred stock; and (iv) contingent obligations to
issue additional shares. Pursuant to the Company's Restated Certificate of
Incorporation, the Company currently has 200 million authorized shares of Common
Stock. Subject to certain limitations, the persons holding such options,
warrants and convertible securities may obtain the shares of Common Stock
underlying such options, warrants and convertible securities at any time. The
issuance of a large number of shares of Common Stock would dilute the percentage
interest of other existing stockholders of the Company.

Item 2. PROPERTIES

           In February 1997, the Company's principal place of business was moved
to 102 Chestnut Ridge Road, Montvale, New Jersey. The Company rents, from an
unaffiliated third party, approximately 50,000 square feet of office space for
approximately $1.2 million per year, plus taxes and utilities. The lease expires
February 2007. The Company's Montvale facility functions as its corporate
headquarters.

           GMSI leases its facilities in Ontario, Canada pursuant to a lease,
with an unaffiliated third party, that expires in April 2005. Annual base rental
payments over the remainder of the lease are approximately $140,000.

           In addition, the Company leases office space in each of the target
markets in which it intends to provide service as it enters a target market. In
addition to office space, the Company must secure leases for its

                                       20

<PAGE>

transmission equipment at suitable locations in each of these U.S. markets. As
of December 31, 1997, the Company had leased office space in 11 of its target
sales markets and transmission sites in 14 of its target sales markets. The
aggregate annual rental payments pursuant to these leases are approximately $5.1
million.

Item 3.    LEGAL PROCEEDINGS

           Harris Adacom. In June 1994, the Company filed a lawsuit against
Harris Adacom Corporation B.V. ("Harris"), a Dutch Corporation, to enforce the
Company's right to repayment of a $3.5 million loan made to Harris in January
1994. In or about May 1994, creditors placed Harris into bankruptcy. In response
to the Company's lawsuit, Harris and its subsidiaries filed a lawsuit against

the Company in the courts of the State of Israel, requesting a declaratory
judgment that the Company entered into a binding agreement for the purchase by
the Company of a significant interest in certain wireless communication business
assets owned by Adacom Technologies Ltd., an affiliate of Harris and an Israeli
publicly traded company, and subsequently breached such agreement. In July 1997,
the plaintiffs filed a motion with the court seeking to amend the Statement of
Claim to assert a claim for monetary damages of approximately $27 million
arising out of the same transaction. This motion is pending. In addition,
plaintiffs are seeking to add Yaron Eitan, the Company's Chairman of the Board,
and Yoram Bibring, who, prior to the Company's reorganization in December 1997,
was President and CEO of Geotek International Networks, Inc. as defendants. The
Company believes that plaintiffs' claims in such action are primarily an attempt
to delay efforts to collect Harris' debt to the Company and that the Company has
meritorious defenses. The Company intends to defend such action vigorously.

                                       ***

           The Company develops and utilizes technology for substantially all of
the services and products it offers and intends to offer and has, from time to
time, been the subject of infringement claims related thereto. It is often
difficult to predict the outcome of such litigation and the amount of damages
that may be awarded. The Company does not believe that any pending or threatened
litigation related to the Company's technology or use thereof will have a
material adverse effect on financial position and results of operations.

           The Company also is, from time to time, a party to litigation, which
may or may not be covered by insurance, arising in the ordinary course of
business. The Company does not believe that results of such litigation, even if
the outcome were unfavorable to the Company, would have a material adverse
effect on its business.

The historical financial results have been reclassified to reflect the 1997
disposition of the Company's communication products segment.

The difference in financial results among the years is influenced by the
following acquisitions and dispositions. In 1993 NB3, GMSI and the remaining
interest in PowerSpectrum, Inc. were acquired and Oram Electric Industries,
Ltd., Oram Power Supplies 1990, Ltd. and Geopower were sold. In 1994, 49%
interests in PBG and DBF were acquired. In 1995, the remaining interests in PBG
and DBF were acquired and the Company increased its interest in GTIL from 56% to
94%. In 1996, the operating assets of the Company's German Networks were
contributed to a 50/50 joint venture, Terrafon, the Company acquired the
remaining 50% interest in MIS, and the Company formed a joint venture in Korea,
Anam Telecom and increased its interest is GTIL from 94% to 97%. During 1997
the Company increased its ownership interest in GTIL to 98%. On November 26,
1997, with the discontinuation of the communications products segment, the
Company sold its 64% interest in BCI for $18.5 million and in December 1997 the
Company entered into two agreements to sell NB3 and Terrafon which sales were
consummated during the first quarter of 1998, See "Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operations."
Accordingly, the Company reduced the carrying value of its investment in

Terrafon to the fair market value.

Item 7  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

The following discussion should be read in conjunction with, and is qualified in
its entirety by, the consolidated financial statements and the notes thereto,
included elsewhere in this report. The consolidated financial statements have
been prepared on a going concern basis which contemplates the realization of
assets and liquidation of liabilities in the ordinary course of business. They
do not include any adjustments to the carrying value of assets and liabilities
that might result from the aforementioned uncertainty (see risk factors
contained in Part I of the form 10-K and footnote 1 to the consolidated
financial statements).

Results of Operations

General

Geotek Communications, Inc. and subsidiaries (collectively, "the Company") have
devoted and expect to continue to devote substantial financial and management
resources to the development and marketing of its Driver Logistics(TM) System
and for the deployment of its frequency hopping multiple access ("FHMA(R)")
Network. The Driver Logistics(TM) System involves a complex integration of
sophisticated digital voice and data applications that utilize hardware and
specialized software. The Company currently operates its FHMA(R) Network in
eleven markets in the United States ("U.S. Network"). The Company, through its
joint ventures, may deploy FHMA(R) systems internationally. Although Management
believes these activities will have a positive effect on the Company's results
of operations in the long term, it is expected to have and has had a substantial
negative effect on the Company's results of operations and financial position in
the short term. The Company expects to incur substantial losses and have
negative cash flow from operations for the foreseeable future, attributable
primarily to the operating, sales, marketing, general and administrative
expenses relating to the roll-out of the U.S. Network as well as an ongoing
investment in engineering and development related to its wireless communications
activities. There can be no assurance that the Company will operate at
profitable levels, have positive cash flow from operations, or continue to
obtain financing to proceed with the implementation of its operating plan.

The Company is in various stages of operations of its networks in
Philadelphia, Washington DC/Baltimore, New York, Boston, Miami, Dallas, Tampa,
San Antonio, Houston and Phoenix and, as a result, has not yet generated
positive cash flow. The Company's existing cash resources at December 31, 1997,
proceeds from the sale of non-strategic assets, and expected cash flow from
operations will be insufficient to fund its current operations and the full
implementation of the Company's business plan in the short and long term. 
The Company's short term business plan is to add customers and customer revenues
and market its Driver Logistics System in its existing markets. The
Company's long term business plan includes: the roll out of the US Network in

over 40 markets; the ongoing deployment of existing international digital
wireless networks; the repayment of convertible debt and redeemable preferred
stock (if such are not converted into equity); and, the repayment of the
Company's line of credit and vendor credit facility and Senior Secured Discount
Notes ("Discount Notes") due 2005.

Based on the Company's current business plan, the Company estimates that it will
need approximately $85 million of additional financing through the end of fiscal
1998, with a portion needed beginning in the second quarter of 1998, to execute
its short term business plan (fiscal 1998) and significant additional financing
thereafter to implement its long term business plan. The amount of additional
financing required will increase if the Company experiences: delays in the
commercial implementation of its U.S. Network (which have occurred in the past);
cost overruns; or other unanticipated cash needs. The Company does not intend to
construct additional U.S. markets or to expand into new international digital
wireless networks until such time as it obtains sufficient financing to do so.
The Company believes that its market by market roll-out plan of the FHMA(R)
Network will permit the Company to control its cash expenditures to a limited
extent by focusing its activities in certain markets while reducing or delaying
its activities in other markets. Additionally, the Company intends and hopes to
renegotiate certain existing cash obligations. The Company will attempt to
obtain additional financing from one or more sources, including, but not limited
to, public or private equity or debt offerings, bank loans, strategic partners,
joint ventures, vendor financing, leasing arrangements, or a

                                       27

<PAGE>

combination thereof. There can be no assurance that the Company will be able to
obtain any such financing or renegotiate existing obligations on acceptable
terms or at all. Any additional equity or debt financing may involve substantial
dilution to the interest of holders of the Company's equity securities. The
failure to obtain the requisite additional capital commencing in the second
quarter would prevent the Company from executing its short and long term
business plan, would result in the Company violating certain contractual and
debt covenants, and would affect and raise substantial doubt about the Company's
ability to continue as a going concern. The Company also expects to impact cash
flow through stringent cost control and expenditure reduction. The consolidated
financial statements have been prepared on a going concern basis which
contemplates the realization of assets and liquidation of liabilities in the
ordinary course of business. They do not include any adjustments to the carrying
value of assets and liabilities that might result from the aforementioned
uncertainty.

The Company has historically grouped its operations into two types of
activities: wireless communications and communications products. On November 26,
1997, the Company discontinued its communication products subsidiary, with the
sale of its 64% interest in Bogen Communications International, Inc. ("BCI"),
for $18.5 million in cash (see discussion below). BCI was primarily engaged in
the development, manufacturing, and marketing of telephone peripherals and sound
and communications equipment. The Company's wireless communications subsidiaries
are currently engaged in marketing and enhancing its Driver Logistics(TM) System
in the United States. Additionally, the wireless communications subsidiaries are

involved in: enhancing the proprietary FHMA(R) Network; selling its proprietary
digital wireless infrastructure equipment internationally; and implementing
digital wireless communications systems internationally. In December 1997, the
Company entered into two definitive agreements to sell its analog trunked mobile
radio services in the United Kingdom and Germany for approximately $82 million
and DM 7 million, respectively. These sales were consummated in February 1998
(see discussion below).

In July 1997, the Company entered into a joint venture agreement with two
Canadian partners for the purpose of deploying FHMA(R) Networks in the provinces
of Ontario, Quebec and British Columbia utilizing 900MHz licenses previously
granted to Geotek Communications Canada Inc., a wholly-owned subsidiary of
GeoNet Communications Canada Inc. ("GeoNet Canada"), by Industry Canada, the
regulatory agency responsible for spectrum allocation in Canada. The Company
invested $2 million in GeoNet Canada and the two Canadian partners invested $1
million each for a total initial investment of $4 million. Additionally, the
Company deposited $2.3 million in a restricted cash account as collateral for
the Canadian partners' investments. The parties reserved the right to withdraw
from the venture.  In the first quarter of 1998, the Canadian partners notified
the Company and subsequently withdrew from the joint venture. The Canadian
partners were repaid their investment from the restricted cash account and the
balance of cash in the joint venture became available to the Company.  The
withdrawal of the Canadian partners resulted in the loss of The Canadian
licenses although the Company may reapply for licenses at such time that the
Company obtains sufficient financing to pursue its deployment of the network in
Canada.

The Company holds a 21% interest in Anam Telecommunications, Inc. ("Anam
Telecom"), a holder of a nationwide trunked radio system license in Korea. The
license covers a geographic area with a population of approximately 45 million
people and is based on the implementation of the Company's FHMA(R) system on an
800MHz frequency. The Company's FHMA(R) system operates in the 900MHz frequency
band in the United States. Anam Telecom commenced commercial operations in
November 1997 in the Seoul region of Korea. The deployment of a FHMA(R)-based
digital system in Korea is subject, but not limited to, the same risks attendant
to the deployment of the Company's digital wireless system in the United States.
Additionally, the devaluation of the Korean Won during the fourth quarter of
1997 or any additional devaluation of the Won could result in an adverse effect
on the ability of Anam Telecom to deploy and operate the FHMA(R) system in
Korea.

In 1997, the Company, through its subsidiary Geotek Technologies, Inc. ("GTI"),
entered into contracts to provide Anam Telecom, as well as Hyundai Electronics
("HEI"), FHMA(R) Network equipment and to supervise network construction. HEI,
in turn, will sell such equipment to the Korean regional operators. To date all

                                       28

<PAGE>

contracts have been denominated in dollars; however, the further devaluation of
the Korean Won may have an adverse effect on the Company's ability to sell
infrastructure in Korea in the future or to negotiate satisfactory agreements or
amendments to existing agreements.


The Company owns a 70% interest in Geotek Argentina S.A. which holds a
nationwide trunked radio system license in Argentina. The license was awarded in
August 1997 and covers metropolitan Buenos Aires, Cordova, Mendoza and Santa Fe.
Geotek Argentina is currently deploying a demonstration site in Buenos Aires.
The deployment of a FHMA(R) Network in Argentina is subject, but not limited to,
the same risks attendant to the deployment of the Company's digital wireless
system in the United States.

In connection with its strategic initiative to focus its efforts on marketing
the Driver Logistics(TM) System in the U.S., in December 1997, the Company
entered into two definitive agreements to sell its European assets. The sales
were consummated in February 1998. Under the first agreement, the Company sold
its operating subsidiary, National Band Three Ltd. ("NB3"), for approximately
$82 million in cash. NB3 provides analog Public Access Mobile Radio ("PAMR")
services to approximately 64,500 subscribers in the United Kingdom and, in 1996,
was awarded a license to operate a digital PAMR network in the United Kingdom.
Under the second agreement, the Company sold its 50/50 joint venture in Germany,
Terrafon, for approximately DM 7 million in cash. Terrafon was established in
December 1996 through a merger of the Company's German networks and RWE
Telliance A.G. ("RWE") mobile radio network and provides analog radio service to
approximately 42,700 subscribers. The use of proceeds from the sales of NB3 and
Terrafon are subject to significant limitations outlined in the Indenture
governing the Company's Discount Notes (see "Liquidity and Capital Resources").

Summary of Operations

The results of operations are presented for continuing operations of the
Company. Results of the discontinued operation, communication products, have
been reclassified.

Consolidated

1997 Compared to 1996

Consolidated revenues from continuing operations increased by 41% in 1997 over
1996 principally due to revenues from GTI for the sale of digital wireless
infrastructure equipment to two customers in Korea which totaled approximately
$22.7 million in 1997.

Consolidated operating expenses increased by 38% in 1997, due to increased
engineering and development activities associated with the enhancement of the
Company's digital wireless network and development of portable customer units;
cost of sales for digital wireless infrastructure (which approximate the revenue
recognized); increase in general and administration expenses to support the U.S.
Network roll-out and international activities; and increased marketing expenses
associated with the roll-out of the U.S. Network.

Consolidated losses from continuing operations increased by $85.4 million to
$225.7 million in 1997.

On a consolidated basis, interest expense increased in 1997 by 20% due to the
accretion of the Discount Notes and the accretion of the value of the warrants
issued in connection with the Discount Notes; the March 1996 issuance of the 12%

Senior Subordinated Convertible Notes ("Convertible Notes"); deemed interest on
the Company's debt that is convertible at a discount to market; and interest on
the Company's line of credit and vendor financing facilities. This increase in
interest was offset by capitalized interest on construction in progress.

Interest income decreased by 34% in 1997 due to a lower level of cash and cash
equivalents held during the year.

                                       29

<PAGE>

1996 Compared to 1995

Consolidated revenues from continuing operations increased by 30% in 1996 over
1995 principally due to subscriber growth on the Company's NB3 network in the
United Kingdom and the inclusion of the Company's German Networks on a
consolidated basis in 1996 prior to the contribution of the operating assets and
liabilities of these networks to the Terrafon joint venture.

Consolidated operating expenses increased by 52% in 1996, due to: increased
engineering and development activities associated with the enhancement of the
Company's digital wireless network and development of customer units, increase
in general and administration expenses to support the U.S. Network roll-out and
international activities, and increased marketing expenses associated with the
roll-out of the U.S. Network.

Consolidated losses from continuing operations increased by $57.2 million to
$140.3 million in 1996.

On a consolidated basis, interest expense increased by 87% in 1996 due to the
accretion of the Discount Notes, the accretion of the value of the warrants
issued in connection with the Discount Notes and the March 1996 issuance of the
Convertible Notes.

Interest income increased in 1996 due to a higher level of cash and cash
equivalents held during the year.

Wireless Communications Activities

As discussed previously, the Company entered into two agreements to sell its
ownership interests in its European assets in the United Kingdom and Germany.
The table below set forth certain information with respect to the results of
operations of the Company's core activities as of December 31, 1997, 1996 and

1997 Compared to 1996

Revenues from wireless communications activities increased by $20.3 million or
146% for the year ended December 31, 1997. This increase was primarily due to an
increase in GTI revenues resulting from the sale of digital wireless
infrastructure equipment to the Company's Korean customers of $22.7 million
which includes the Company's joint venture in Korea (for which the Company
eliminates its 21% ownership interest of revenue). The cost related to the sales
to Korea approximate the revenues recognized. Additionally, revenues increased
due to the increase in the number of customers using the U.S. Network. The
increase in negative gross profit for the Company is primarily the result of
increased direct service costs related to the roll-out of the digital network in
additional

                                       30

<PAGE>

markets in the U.S. Network, the cost of which are currently not covered by
revenues, and the cost of inventory of customer handsets which are marketed
under a promotion program at an amount less than cost.

Engineering and development costs related to the digital wireless system and
customer handsets increased $5.1 million or 15% for the year ended December 31,
1997 and 1996, respectively. The increase was due to one time development costs
for the portable unit and related portable docking station as well as switch
development costs. The Company expects significant engineering and development
costs to continue in the future in connection with continued enhancements to the
FHMA(R) Network and Driver Logistics(TM) System, but at lower levels than 1997.

The Company's U.S. Network is in various stages of operations in 11 markets
throughout the United States and, accordingly, continues to put in place its
marketing, engineering, operations and administrative staff and systems. During
the third quarter of 1997, the Company commenced operations in Houston, Phoenix
and San Antonio. Marketing expenses increased by approximately $1.7 million or
7% due to the U.S. Network marketing programs and an increase in staff needed to
execute the roll-out of the U.S. Network in its markets.

The increase in the Company's 1997 general and administrative expenses of $11.3
million or 41% was due to costs associated the Company's financing activities
related to the construction of the U.S. Network.

The Company's equity in losses of less than 50% owned entities in 1997 was
primarily attributable to the results of the Company's Korean joint ventures. As
discussed above, the Company's Korean joint ventures are in the process of
establishing a digital network in Korea. It is expected that these entities will

continue to generate substantial losses in the near future.

Wireless communications activities generated a loss before interest, taxes,
amortization and depreciation of $148.6 million for the year ended December 31,
1997 compared to $99.2 million in 1996. This increase was primarily due to costs
related to the
ongoing roll-out of the digital wireless network in the U.S. and enhancement of
the digital wireless network.

1996 Compared to 1995

Revenues from wireless communications activities increased by $3.8 million to
$13.9 million or 38% for the year ended December 31, 1996 compared to 1995. This
increase was primarily due to the increase for GMSI, Inc.'s contract related to
the Singapore taxi fleet as well as revenues from Geotest Inc., a subsidiary
sold in 1996, which recorded revenues of $3.9 million and $2.8 million in 1996
and 1995, respectively.

The increase in negative gross profit for the U.S. Network was primarily the
result of increased direct costs related to the roll-out, the cost of which are
currently not covered by revenues, and the write-down of pre-production
inventory to replacement cost. In 1995, the U.S. Network included the results of
the Company's MetroNet subsidiary. In November 1995, the Company exchanged the
assets of MetroNet, primarily 800MHz licenses, with Nextel Communications Inc.
for certain 900MHz licenses.

Engineering and development expenses (net of government grants of $0.3 million
and $5.9 million in 1996 and 1995, respectively) related to the digital wireless
system and customer units were $34.5 million for the year ended December 31,
1996 compared to $33.3 million for the same period of 1995. The increase in the
1996 expense was primarily attributable to costs related to the development of
the U.S. Network's commercial customer unit and enhancements to the Company's
proprietary digital wireless network, including system software. In addition,
the Company expensed the $1.9 million excess of the consideration paid over the
fair value of the net assets received in the purchase of MIS Information Systems
Holdings Ltd. as the acquisition primarily related to ongoing software
development projects in process. The Company expects significant engineering and
development expenses to continue in the future in connection with enhancements
made to the

                                       31

system and subscriber unit.

The Company was in the process of rolling out its wireless service over its
proprietary digital wireless network in the United States and, accordingly,
continued to put in place its marketing, engineering, operations and
administrative staff and systems. Marketing expenses increased by approximately
$11.7 million or 97% due to the U.S. Network marketing programs and an increase
in staff needed to execute the roll-out of the U.S. Network in the initial 1996
markets.


General and administrative expense increased $8.7 million or 46% due to an
increase in administrative staff needed to support the beginning of the U.S.
Network roll-out and the Company's expanding international business development
activities.

The Company's equity in losses of less than 50% owned entities for the year
ended December 31, 1996 and 1995 is attributable primarily to the results of the
Korean joint ventures. The loss for 1996 is presented net of a $1.4 million
reimbursement received by the Company from Anam Telecom for expenses incurred by
the Company on behalf of its Korean joint venture in connection with the trunked
radio system license process. As discussed above, the Company's Korean joint
ventures are in the process of establishing a digital network in Korea. It is
expected that these entities will continue to generate substantial losses in the
near future.

Wireless communications activities generated a loss before interest, taxes,
amortization and depreciation of $99.2 million for the year ended December 31,
1996 compared to $63.5 million in 1995. This increase is primarily due to costs
related to the commencement of the roll-out of the digital wireless
communication system for the U.S.

As previously discussed, in December, 1997, the Company entered into two
definitive agreements to sell its analog trunked mobile radio services in the
United Kingdom and Germany for approximately $82 million and DM 7 million,
respectively. These sales were consummated in February 1998. The net assets of
NB3 and investment in Terrafon at December 31, 1997 are presented as net assets
held for sale. This transaction will result in a gain of approximately $60.2
million which will be recognized in the first quarter of 1998. Upon the decision
to sell Terrafon, the Company reduced the carrying value of the investment to
fair market value. The loss, which is included in Equity in loss of investees
at December 31, 1997, was $12.9 million.

Discontinued Operations -- Communications Products Activities

On November 26, 1997, the Company discontinued its communication products
segment with the sale of its 64% interest in BCI for $18.5 million in cash. The
capital stock of BCI was pledged to the holders of the Company's Discount Notes.
The Company's debt covenants and amendment thereto place timing restrictions on
the Company's ability to utilize the proceeds for working capital purposes. At
December 31, 1997, the Company had received $18.5 million in proceeds, however, 
$9.1 million is reflected in the 1997 consolidated balance sheet under the
caption Restricted Cash. This amount was released based upon the completion
of certain conditions during the first quarter of 1998. This transaction
resulted in a 1997 gain of approximately $3.8 million.

Liquidity and Capital Resources

The following discussion of liquidity and capital resources, among other things,
compares the Company's financial and cash position as of December 31, 1997 to
the Company's financial and cash position as of December 31, 1996 (See footnote
1 to the consolidated financial statements).

The Company requires significant additional capital, commencing in the second
quarter of 1998; to fund its current operations, working capital, and debt
service requirements and to implement its strategy of providing WorkPower for
the Road through the Driver Logistics(TM) System. The Company estimates that the
amount required for Fiscal 1998 is approximately $85 million. In furtherance of
its capital financing strategy in fiscal 1997, the Company sold $55 million in
convertible preferred stock and renegotiated its $40.0 million line of credit
facility. At December 31, 1997, the Company had $13.4 million of cash and cash
equivalents. In November 1997, the Company discontinued its communication
products segment. At December 31, 1997, $9.1 million of the net proceeds is
included in restricted cash and was released during the first quarter of 1998.

The Company has a $100.0 million vendor credit facility, the last $50 million of
which is subject to the satisfaction of certain conditions, with Hughes Network
Systems ("HNS"). The credit facility is for the purchase of infrastructure
equipment for which the Company began accepting delivery in October 1997. At
December 31, 1997, $10.4 million of this facility was utilized. Additionally,
the Company entered into two agreements to sell its interests in NB3 and
Terrafon for approximately $82 million and DM 7 million, respectively. The
Company's ability to utilize the proceeds of the sales is limited in
accordance with the amended Indenture governing the Company's Discount Notes.
Under the Indenture, the Company must repay the pro-rata portion of the
accreted value of the Discount Notes

                                       33

<PAGE>

in the aggregate of 20% of the net proceeds. In addition, 40% of the net
proceeds must be used for the purchase of qualifying capital expenditures. The
balance of the net proceeds, 40%, can be used for general corporate purposes and
working capital with funds accessible under certain time restrictions beginning
in February 1998.


The Company's short term cash needs related to fiscal 1998 are attributable
primarily to debt service requirements, capital expenditures, inventory,
marketing, general and administrative expenses, trade payables and engineering
and development costs associated with the marketing of its Driver Logistic(TM)
System and the implementation and deployment of its digital FHMA(R) Networks.
One of the advantages of the Company's FHMA(R) Network is its modularity, which
allows the Company to execute a flexible roll-out plan requiring a relatively
low investment in infrastructure in a given geographical area (compared to other
wireless communications systems) in order to provide initial commercial service.
Additionally, the Company is rolling out its U.S. Network market by market and
is targeting customers which require primarily local or regional coverage.
Management believes that this modularity and its local deployment provides the
Company flexibility in controlling its financial resources by accelerating or
slowing down the rate at which the U.S. Network is rolled out in various markets
without materially impacting the business results, or cash flows, of its then
operating networks.

The Company estimates that a minimum average initial capital investment of
approximately $7 million is required to roll-out its U.S. network in an average
target market. Additional expenditures will be required later in a given market
if and when increased coverage or capacity is needed. In addition, the Company
currently estimates that it will continue engineering and development activities
during the next 12 months but at substantially lower levels than in 1997. These
activities include enhancements to the Driver Logistic(TM) System and FHMA(R)
Network including additional hardware and software applications.

During 1997, cash and cash equivalents decreased by $89.3 million to $ 13.4
million while working capital decreased by $129.7 million to ($18.4) million.

Operating Activities

Cash utilized in connection with operating activities, for the year ended
December 31, 1997, amounted to $117.1 million. This included changes in
operating assets and liabilities of $11.3 million. This change was primarily
related to a decrease in prepaid expenses of $2.7 million, a decrease in
receivables of $1.3 million, and an increase in accounts payable and accrued
expenses of $24.8 million.

The Company's U.S. Network operations extended sales and marketing promotions
under which a dealer will be eligible to purchase equipment at a discount based
on achievement of sales goals. According to the Company's policy in which the
Company does not adjust inventory values for sales promotions, the Company has
neither provided an accrual nor adjusted the $13.1 million carrying value of the
U.S. Network inventory for promotions as of December 31, 1997. The results of
promotions will be recorded commensurate with the sale.

Investing Activities

Cash used in investing activities was $67.0 million for the year ended December
31, 1997. The Company expended $61.7 million to acquire equipment during 1997
and capitalized $8.6 million in interest on construction in progress and
pre-commercial FCC licenses. Commensurate with the definitive agreement to sell
NB3 and reclassification of NB3's assets and liabilities to net assets held for

sale, NB3's cash balance of $4.5 million was reclassified to net assets held for
sale.

In November 1997, the Company sold its 64% interest in BCI. The proceeds from
the sale were $18.5 million.

                                       34

<PAGE>

During the first quarter of 1997, the Company contributed approximately $2.6
million to Terrafon, the Company's joint venture in Germany, representing the
initial capital call for the Company's 50% portion of Terrafon's estimated 1997
operating capital. During the second quarter of 1997, the Company contributed
$4.7 million to Anam Telecom, the Company's joint venture in Korea, representing
the Company's 21% portion of the 1997 capital requirements. As discussed
previously, the Company entered into a joint venture agreement in Canada in July
1997 under which the Company made an initial investment of $2.0 million and
placed $2.3 million into a restricted account as collateral for the
co-investors. In January 1998, this $2.3 million was used to repay the investors
for their initial investment and the cash in the joint venture became available
to the Company.

Financing Activities

In January 1997, the Company sold 500 shares of its Series P Cumulative
Convertible Preferred Stock ("Series P Stock") to a group of investors
affiliated with George Soros for an aggregate purchase price of $25 million. The
Series P Stock pays dividends in either shares of the Company's Common Stock or
cash at a rate of 10% per annum (12% per annum after a dividend payment failure)
at the option of the Company. Additionally, commencing April 1, 1997, each share
of Series P Stock is convertible by the holder into the number of shares of the
Company's Common Stock as obtained by dividing the $50,000 stated value per
share plus any accrued or unpaid dividends at the date of conversion by the
lowest daily volume weighted average price of the Company's Common Stock during
the four trading days immediately preceding conversion multiplied by the
conversion factor (the conversion factor began at 100%, became 95%, and 90% on
June 29, 1997 and December 31, 1997, respectively, and becomes 88% on June 29,
1998). However, the holder could only convert up to a maximum of 20% prior to
June 30, 1997, an additional 30% prior to December 31, 1997, and can convert an
additional 30% prior to June 29, 1998 and the remainder thereafter. In
connection with this transaction, the Company issued warrants to purchase
850,000 shares of the Company's Common Stock at $9.2625 per share (subject to
adjustment in certain circumstances). The warrants are exercisable at any time,
and from time to time, before June 30, 2000.

In April 1997, the Company and S-C Rig Investments - III, L.P. ("S-C Rig"), a
significant stockholder of the Company and an investment group affiliated with
George Soros, modified the terms of the Senior Loan Agreement whereby S-C Rig
made a $40.0 million unsecured credit facility ("S-C Rig Credit Facility")
available to the Company. Under the modified terms of the S-C Rig Credit
Facility, all borrowings are required to be made within three years from the
initial establishment of the credit facility. The borrowings will accrue
interest at a rate of 8% per annum and will mature five years from the date of

the final borrowing thereunder. Original terms of the S-C Rig Credit Facility
were a 10% interest rate per annum and a four year term from the final borrowing
which was required to be made within two years from the establishment of the
Credit Facility. In connection with the modification to the S-C Rig Credit
Facility, the Company lowered the exercise price of the warrants to purchase
approximately 4.2 million shares of common stock (the "Warrant Shares") from
$9.50 to $6.00 per share and extended the Warrant Shares termination date from
April 2001 to April 2003. As of December 31, 1997, $40.0 million was outstanding
under this facility.

In August 1997, the Company, in a private placement, sold 600 shares of its
Series Q Convertible Preferred Stock ("Series Q Stock") for an aggregate
purchase price of $30 million. The Series Q Stock pays dividends in either
shares of the Company's Common Stock or cash at a rate of 10% per annum (12% per
annum after a dividend payment failure) at the option of the Company.
Additionally, commencing October 10, 1997, each share of Series Q Stock is
convertible by the holder into the number of shares of the Company's Common
Stock as obtained by dividing the $50,000 stated value per share plus any
accrued or unpaid dividends at the date of conversion by the lowest daily volume
weighted average price of the Company's Common Stock during the four trading
days immediately preceding conversion multiplied by the conversion factor (the
conversion factor began at 100% and becomes 95%, and 90% on January 1, 1998 and
April 1, 1998, respectively). However, the holder could only convert up to a
maximum of 25% prior to January 1, 1998, an additional 25% prior to March 31,
1998, an additional 30% prior to June 30, 1998 and the remainder

                                       35

<PAGE>

thereafter. In connection with this transaction, the Company issued warrants to
purchase 1,800,000 shares of the Company's Common Stock at $8.00 per share
(subject to adjustment in certain circumstances). The warrants are exercisable
at any time, and from time to time, before February 10, 2001.

In February 1998, the Company completed an exchange offer whereby certain
holders of the Company's Series O Cumulative Convertible Preferred Stock
("Series O Stock") and Series Q Cumulative Convertible Preferred Stock ("Series
Q Stock") exchanged $22.4 million for shares of the Company's Series R Preferred
Stock ("Series R Stock") and Series S Preferred Stock ("Series S Stock"), whose
conversion price is fixed at an amount above the market price of the Company's
Common Stock. The $15.6 million of Series R Stock is convertible at $2.00 per
share and the $6.5 million of Series S Stock is convertible at $4.00 per share
which is adjusted under certain circumstance to $3.00 or at 110% of the market
price. Additionally, the Company lowered the exercise price of 3.0 million of
the Series O Stock and Series Q Stock warrants to $4.00 per share.
Under the exchange the holders also converted $12.1 million of Series O and Q
stock into Common Stock at $1.00 per share.

In October 1997, in connection with the receipt of infrastructure equipment from
HNS, the Company began drawing down on its $100 million vendor credit facility
with HNS. At December 31, 1997, approximately $10.4 million was drawn down and
$89.6 million was available, the last $50 million of which is subject to
satisfaction of certain conditions.


The Company paid cash dividends totaling approximately $5.1 million on its
outstanding preferred stocks during the year ended December 31, 1997 and
proceeds from the exercise of warrants and options totaled approximately $0.2
million.

As discussed previously, the Company must raise additional capital beginning in
the second quarter of 1998 to continue financing its current operations and to
implement its business plan in the short (fiscal 1998) and the long term.  The
Company's long term capital needs relate to: the planned roll-out of the U.S.
Network in over 40 cities; the repayment of convertible debt and redeemable
preferred stock (if such are not converted into equity); the repayment of the
Company's vendor credit and Discount Notes due 2005; the financing of existing
international digital wireless networks; and the acquisition of spectrum in the
United States and internationally. The amount of additional financing required
will increase if the Company experiences: delays in the commercial
implementation of its U.S. Network (which have occurred in the past); cost
overruns; or, unanticipated cash needs. Although the Company believes that its
market-by-market roll-out plan of its FHMA(R) network will permit the Company to
control its cash expenditures to a limited extent by focusing its activities in
certain markets while reducing or delaying its activities in other markets, the
failure by the Company to obtain necessary financing on a timely basis will
prevent the Company from executing its short (fiscal 1998) and long term
business plan. The Company does not intend to construct additional U.S. markets
or to expand into new international digital wireless networks until such time
that it obtains sufficient financing to do so.

The Company is considering a number of alternatives to raise additional
financing including, but not limited to, public or private equity or debt
financing, bank loans, strategic partners, joint ventures, vendor financing,
leasing arrangements, or a combination of these sources. The documents governing
the Company's outstanding indebtedness impose certain significant operating and
financial restrictions on the Company which limit, among other things, the
Company's ability to incur indebtedness, make prepayments of certain
indebtedness, pay dividends on common stock, make investments and engage in
mergers and acquisitions. There can be no assurance that the Company will be
able to obtain any such financing on acceptable terms or at all. The failure to
obtain such financing will prevent the Company from fully executing its short
and long term business plan, would result in the Company violating certain
contractual covenants and would affect the Company's ability to continue as a
going concern.

Recently Issued Accounting Pronouncements

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 130, "Reporting Comprehensive Income"
("SFAS No. 130"). SFAS No. 130 establishes

                                       36

<PAGE>

standards for reporting and display of comprehensive income and its components
in a full set of general-purpose financial statements. SFAS No. 130 is effective

for fiscal years beginning after December 15, 1997. Reclassification of
financial statements for earlier periods provided for comparative purposes is
required. The adoption of SFAS No. 130 will have no impact on the Company's
consolidated results of operations, financial position or cash flows.

In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information" ("SFAS No. 131"). SFAS No. 131 establishes
standards for the way that public business enterprises report information about
operating segments in annual financial statements and requires that those
enterprises report selected information about operating segments in interim
financial reports issued to shareholders. It also establishes standards for
related disclosures about products and services, geographic area, and major
customers. SFAS No. 131 is effective for financial statements for fiscal years
beginning after December 15, 1997. The adoption of SFAS No. 131 will have no
impact on the Company's consolidated results of operations, financial position
or cash flows but may affect the determination and presentation of reportable
segments; although it may impact the disclosures of reportable segment data, the
Company is currently assessing the disclosure requirements.

                       REPORT OF INDEPENDENT ACCOUNTANTS

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


To the Board of Directors and Shareholders
of Geotek Communications, Inc.:


We have audited the consolidated financial statements and the consolidated
financial statement schedule of Geotek Communications, Inc. and Subsidiaries as
listed in Item 14(a)(1) and (2) of this Form 10-K. The consolidated financial
statements and the consolidated financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements and the consolidated
financial statement schedule based on our audits. We did not audit the financial
statements of Geotek Technologies Israel (1992) Ltd, a consolidated
subsidiary, which statements reflect revenues of approximately 32%, 0% and 0%
and losses from continuing operations of approximately 10%, 13%, and 12% of the
corresponding consolidated totals in 1997, 1996 and 1995, respectively. These
statements were audited by other auditors whose report, which included an
explanatory paragraph with respect to Geotek Technologies Israel (1992) Ltd.'s
ability to continue as a going concern, has been furnished to us, and our
opinion, insofar as it relates to the amounts included for Geotek Technologies
Israel (1992) Ltd. for 1997, 1996, and 1995, is based solely on the report of
other auditors.

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 consolidated financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the
consolidated financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall consolidated financial statement presentation.
We believe that our audits, and the report of other auditors, provide a
reasonable basis for our opinion.

In our opinion, based on our audits and the report of other auditors, the
consolidated financial statements referred to above presently fairly, in all
material respects, the consolidated financial position of Geotek
Communications, Inc. and Subsidiaries as of December 31, 1997 and 1996, and
the consolidated results of its operations and its cash flows for each of the
three years in the period ended December 31, 1997, in conformity with
generally accepted accounting principles. In addition, in our opinion, based
on our audits and the report of other auditors, the consolidated financial
statement schedule referred to above, when considered in relation to the basic
financial statements taken as a whole, presents fairly, in all material
respects, the information required to be included therein.


The consolidated financial statements referred to above have been prepared
assuming that the Company will continue as a going concern. As discussed in
Note 1 to the consolidated financial statements, the Company has suffered
recurring losses from operations, has significant debt obligations and has
negative operating and investing cash flows that raise substantial doubt about
its ability to continue as a going concern. Management's plans in regard to
these matters are also described in Note 1. The consolidated financial
statements do not include any adjustments to reflect the possible future
effects on the recoverability and classification of assets, including
long-lived assets which is dependent on the Company's ability to implement its
operating plans, or the amounts and classification of liabilities, that may
result from the outcome of this uncertainty.

                AUDITORS= REPORT TO THE BOARD OF DIRECTORS OF


GEOTEK TECHNOLOGIES ISRAEL (1992) LTD.

We have audited the accompanying balance sheets of GEOTEK TECHNOLOGIES ISRAEL
(1992) LTD. (f/k/a PowerSpectrum Technology Ltd.) as of  December 31, 1997 and
1996, and the statements of operations, changes in  shareholders' equity and
statements of cash flows for the years ended December 31, 1997,  1996, and 1995.
These financial statements are the responsibility of the  Company's Board of
Directors and management. Our responsibility is to express  an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards
in Israel (which do not materially differ from those established by the American
Institute of Certified Public Accountants), including those prescribed under 
the Auditors' Regulations (Auditor's Mode of Performance), 1973. Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement, whether
caused by an error in the financial statements or by an irregularity therein. 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 the Company's Board
of Directors and management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a fair basis for our
opinion.

The financial statements referred to above have been prepared on the basis of
historical cost, restated for the general purchasing power of the Israeli
currency, in conformity with statements of the Institute of Certified Public
Accountants in Israel ("ICPA"). Condensed financial statements in nominal NIS
values as required according to the guidelines of the ICPA, are not presented.


In our opinion, except for the omission of the condensed financial statements in
nominal NIS values, the financial statements referred to above present fairly,
in all material respects, the financial position of the Company as of December
31, 1997 and 1996 and the results of its operations, changes in shareholders'
equity and cash flows for the years ended December 31, 1997, 1996 and 1995, in
conformity with generally accepted accounting principles.

The financial statements referred to above have been prepared assuming that the
Company will continue as a going concern.  As discussed in Note 1B to the
financial statements, the Company has suffered recurring losses from operations
and has incurred significant working capital and shareholders' deficit that
raise substantial doubt about its ability to continue as a going concern. 
Recoverability of the Company's assets including intangible and other long-lived
assets, is dependent on the Company's ability to receive further funding and
purchase orders from its shareholders or others.  The financial statements do
not include any adjustments to reflect the possible future effects on the
recoverability and classification of assets, or the amounts and classification
of liabilities, that may result from the outcome of this uncertainty.

Pursuant to Section 211 of the Companies Ordinance (New Version) 1983, we state
that we have obtained all the information and explanations we have required and
that our opinion on the above mentioned financial statements is given according
to the best of our information and the explanations received by us and as shown
by the books of the Company.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    Basis of Presentation and Summary of Significant Accounting Policies:

      Basis of Presentation and Principles of Consolidation
      The consolidated financial statements of Geotek Communications, Inc.
      ("the Company") include all wholly-owned, majority-owned and controlled
      subsidiaries. The Company accounts for 20%-50% owned entities by the
      equity method. All significant intercompany accounts and transactions
      have been eliminated.

      Certain amounts in the 1996 and 1995 financial statements and notes have
      been reclassified to conform to the 1997 presentation.

      The consolidated financial statements have been prepared on a going
      concern basis, which contemplates the realization of assets and
      liquidation of liabilities in the ordinary course of business. The
      Company's existing cash resources at December 31, 1997, proceeds from
      the sale of non-strategic assets (see Note 2), lines of credit
      facilities (see Note 8) and expected cash flow from operations will be
      insufficient to fund its current operations and the implementation of
      the Company's business plan in the short and long term. The Company's
      short term business plan is to add customers and customer revenues and
      market its Driver Logistic(TM) Systems in its existing eleven markets.
      The Company's long term business plan includes: the rollout of the U.S.
      Network in over 40 markets; the ongoing deployment of existing
      international wireless networks; the repayment of convertible debt and
      redeemable preferred stock (if such are not converted into equity); and
      the repayment of the Company's line of credit and vendor credit
      facilities and Discount Notes. Further, under terms of the Indenture
      governing the Company's 15% Senior Secured Discount Notes ("Discount
      Notes") and other contractual commitments, the Company is limited in the
      use of proceeds from the sale of assets and indebtedness as the
      indenture restricts the availability of cash for general corporate
      purposes (see Note 2).

      The Company is in various stages of operations in eleven markets in
      Philadelphia, Washington D.C./Baltimore, New York, Boston, Miami,
      Dallas, Tampa, San Antonio, Houston and Phoenix and, as a result, has
      not yet generated positive cash flow. Thus, the Company must raise
      significant additional capital, a portion of which must be raised
      beginning in the second quarter fiscal 1998, to fund current operating
      losses, working capital, debt service and capital expenditures. The
      Company does not intend to construct additional markets in the U.S. or
      expand into new international FHMA(R) Networks until such time as it
      obtains sufficient additional financing to do so. Additionally, the
      Company expects to re-negotiate certain cash commitments by deferring
      payments or making payments in shares of the Company's common stock to
      decrease its short and long term cash requirements. In addition to cash
      receipts from anticipated customer growth in the current year, the
      Company will attempt to obtain additional financing from one or more

      sources including, but not limited to, public or private equity or debt
      offerings, bank loans, strategic partners, joint ventures, vendor
      financing, leasing arrangements, or a combination thereof. The Company
      also expects to impact cash flow through stringent cost control and
      expenditure reductions. There can be no assurance that the Company will
      be able to obtain any such financing on acceptable terms or at all. Any
      additional equity or debt financing may involve substantial dilution to
      the interest of holders of the Company's debt and equity securities. The
      failure to obtain the requisite additional capital would prevent the
      Company from executing its short (fiscal 1998) and long term business
      plans, would result in the Company violating certain contractual and
      debt covenants (see Note 8) and raises substantial doubt about the
      Company's ability to continue as a going concern. The accompanying
      consolidated financial statements do not include any adjustments to
      reflect the possible future effects on the recoverability and
      classification of assets or the amounts and classification of
      liabilities which might result from this uncertainty.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

      Risks and Uncertainties

      The Company's Driver Logistics(TM) System using the Company's FHMA(R)
      digital wireless network involves a complex integration of sophisticated
      voice and data applications. The implementation of the FHMA(R) System to
      date has raised numerous technical difficulties. Additional technical
      difficulties may arise from time to time as the Company continues to
      make hardware and software modifications, add new functionality to the
      Driver Logistics(TM) System and increase the number of customers in a
      particular market. The introduction of additional services is expected
      to require testing and hardware and software modifications in order to
      integrate such services with the existing FHMA(R) System services, which
      may present technical problems. During the fourth quarter of 1997, the
      Company began introducing new operating system software in its current
      U.S. markets. Integration of such software required modification to the
      network and the hardware utilized by the Company's customers, as well as
      testing. The success and timing of the integration of new services and
      new software and/or the negative impact, if any, to the Company's
      customers from an interruption of service cannot be predicted. In
      addition, new software may be required to solve technical difficulties
      that may arise in the operation and performance of the FHMA(R) System as
      additional users are added in a particular market or as the coverage
      area in any market is increased. Furthermore, each of the Company's
      United States target markets could present unique technical issues due
      to differences in geography and topography, which may also require new
      system software. Delays in the integration of new services and new
      system software, or an adverse reaction from the Company's customers,
      could have a material adverse effect on the Company's ability to
      successfully market its Driver Logistics(TM) System and on the financial
      position, cash flow and results of operations.


      The Company may eventually need additional spectrum in certain of its
      more populated markets, beyond what it has already. Because spectrum is
      a finite resource, there can be no assurance that the Company will be
      able to obtain additional spectrum to meet its possible needs.
      Additionally, acquisition of additional spectrum may require significant
      capital resources. The inability of the Company to obtain additional
      spectrum could limit its ability to expand its services and increase the
      number of customers on its system in a given market.

      There are only a limited number of existing communications towers
      capable of providing the Company with sufficient coverage for its radio
      transmissions and support its transmission equipment. If the Company
      cannot obtain leases for existing towers, it may be required to purchase
      sites, obtain necessary permits and build such towers which could take
      up to one year for each tower. If the Company is required to build new
      towers, additional financing may be required and the deployment of the
      FHMA(R) System in one or more of its target U.S. markets could be
      delayed.

      Additionally, the Company's joint venture in Korea (see Note 4) is
      currently deploying an 800MHz FHMA(R) System in Korea. The Company also
      sells FHMA(R) System infrastructure to unrelated parties in Korea. The
      deployment of such a network is subject to the same risks and estimates
      attendant to the U.S. network rollout in addition to currency exchange
      rate fluctuation, international incidents, economic downturn and changes
      in government policy.

      The Company is dependent upon a relatively small number of manufacturers
      for its products. Rafael Armament Development Authority, a related party
      and a division of the Israeli Ministry of Defense ("Rafael"), and Hughes
      Network Systems ("HNS"), a related party and a unit of GM Hughes
      Electronics, currently are manufacturing the base station equipment for
      the U.S. wireless network on a schedule that is intended to enable the
      Company to meet its projected roll-out. Other third parties, including
      HNS and Farbell Electronics ("Farbell") currently are manufacturing
      customer units and certain other components of the system hardware for
      the U.S. wireless network on a schedule to meet anticipated customer
      demand. There can be no assurance that such third parties will deliver
      such equipment on a timely basis. Although the Company believes that it

                                    F - 11
<PAGE>

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

      can obtain all components necessary to build the digital wireless system
      and Driver Logistics(TM) System from other sources, it may encounter
      delays in the event of a component shortage due to the time needed to
      identify alternative sources and manufacture substitute components.
      Failure to obtain hardware components on a timely basis or at
      satisfactory prices could result in delays or cost overruns in the
      implementation of the U.S. digital wireless system and Driver
      Logistics(TM) System.


      Many of the target customers for the Company currently use one or more
      wireless communications services. In order to compete effectively, the
      Company must attract a portion of its target customers from their
      existing providers. The Company's marketing strategy emphasizes its
      Driver Logistics(TM) System, an integrated package of voice and data
      services, which the Company believes differentiates it from wireless
      communications and logistics providers. However, there can be no
      assurance that potential customers will perceive the Company's services
      to be superior to those offered by wireless communications providers.

      Long-Lived Assets

      In 1996, the Company adopted Financial Accounting Standards Board
      ("FASB") Statement of Financial Accounting Standards ("SFAS") No. 121
      "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
      Assets to be Disposed of". This statement requires that long-lived
      assets and certain identifiable intangibles be periodically 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 undiscounted 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 exceeds 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 (see Note 2). Pursuant to SFAS
      No. 121, the Company periodically reviews long-lived assets, including
      its property, plant and equipment, intangible assets and investments in
      affiliates, whenever events or changes in circumstances indicate that
      the carrying amount of such assets may not be recoverable. When such
      circumstances occur, the Company evaluates the possible effects on the
      carrying amount of such assets. The adoption of this Statement did not
      have a significant effect on the Company's financial position, results
      of operations, or liquidity.

      The Company's estimates of future gross revenues and operating cash
      flows, the remaining estimated lives of long-lived assets, or both,
      could be reduced in the future due to changes in, among other things,
      technology, government regulation, available financing or competition.
      The Company's estimate of future gross revenues and operating cash flows
      assumes that the Company will successfully implement its short and long
      term business plan and achieve the growth in market penetration and
      customers and will continue as a going concern (see Basis of
      Presentation above). There is no assurance that the Company can
      successfully implement its plan or that it will be able to achieve
      positive cash flow from any operating activities. As a result, the
      carrying amounts of long-lived assets could be reduced by an amount
      which may be material to the consolidated financial statements.

      Use of Estimates

      The preparation of financial statements in conformity with generally
      accepted accounting principles requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities

      and disclosure of contingent assets and liabilities as of the date of
      the financial statements and revenues and expenses during the period
      reported. Actual results could differ from those estimates and have a
      material adverse effect on the financial position of the Company.
      Estimates are used for, among other things: revenue recognition, 
      allowance for doubtful accounts; inventory reserve for the lower of cost 
      or market; product warranty reserves; depreciation and amortization; and, 
      the estimated lives of assets and recoverability of long lived assets, 
      including intangibles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

      Revenue Recognition

      Product sales related to handsets and telephone peripherals are
      recognized on shipment. Revenues for service income are recognized when
      services are provided. Deferred revenues are recognized when the
      customer is billed in advance and are recorded in income in the period
      to which the advance billing relates.

      Revenues and estimates of profit for the Company's Geotek Technologies,
      Inc. ("GTI") and GMSI, Inc. ("GMSI") subsidiaries relating to long term
      construction contracts for the sale of digital wireless networks and
      wireless dispatch products are recognized under the percentage of
      completion method of accounting using the cost to cost methodology.
      Profit estimates are revised periodically based upon changes in facts
      and circumstances. Any losses on contracts are recognized immediately.

      Inventories

      Inventories, which include handsets and telephone peripherals, are
      stated at the lower of cost (first-in, first-out method) or market. The
      carrying value of handsets held for resale to the Company's subscribers
      are not adjusted to reflect promotional discounts which are recognized
      upon the sale to the customer.

      Cash Equivalents

      Cash equivalents are highly liquid debt instruments purchased with an
      original maturity of three months or less, and are considered to be cash
      equivalents for cash flow reporting purposes.

      Restricted Cash

      Restricted cash includes certain proceeds from the sale of certain
      assets and compensating balances under Letters of Credit. Under the
      terms and conditions of the Indenture governing the Company's Discount
      Notes, and amendments thereto, the use of proceeds from the sale of
      assets are restricted. At December 31, 1997, $9.1 million from the sale
      of Bogen Communications International Inc. ("BCI") was restricted and
      subsequently released during the first quarter of 1998.


      Concentration of Credit Risk and Off-Balance-Sheet Risks

      The Company provides mobile radio services to commercial customers in
      the United States, Europe (see Note 2) and Korea under contractual
      arrangements. The Company performs ongoing credit evaluations of its
      commercial customers and generally does not require collateral. The
      Company maintains reserves for potential losses from these contractual
      arrangements. Credit risk with respect to accounts receivable for the
      U.S. network is limited due to the large number of customers and their
      industry and geographic dispersion. The Company's Israel subsidiary,
      Geotek Technologies Israel ("GTI - Israel"), has credit risk from
      contracts with two customers in Korea and is prohibited from making
      certain payments, including loans, to entities outside of Israel without
      the Bank of Israel's approval. The subsidiaries are permitted, however,
      to distribute dividends, reimburse expenses and make other specific
      payments.

      Property, Plant and Equipment

      Property, plant and equipment is stated at cost. Property, plant and
      equipment obtained through acquisition is recorded at the fair value at
      the date of acquisition. Depreciation and amortization are provided
      principally by the straight-line method over the estimated useful lives
      of the related assets which range between 3 and 10 years, commencing
      with commercial operations. Gains or losses arising from dispositions
      are recorded in operations.

      Interest costs incurred on borrowings during the construction phase of
      the network infrastructure buildout for each market (until the assets
      are substantially complete and ready for use) are capitalized and
      depreciated over

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

      the service life of the equipment. Interest capitalized on construction
      in progress amounted to $2.6 million for 1997 and 1996 and $0.5 million
      in 1995.

      Intangible Assets

      Goodwill -The excess of cost over the fair value of net assets acquired
      is amortized on a straight-line basis over ten to twenty years. At each
      balance sheet date management assesses whether there has been an other
      than temporary impairment in the value of goodwill by comparing
      anticipated undiscounted future cash flows from operating activities
      with the carrying value of goodwill. For those assets where a decision
      has been made to sell or dispose, once made, management looks to the
      estimated proceeds from the sale of such assets.

      Federal Communications Commission ("FCC") Licenses - FCC and other

      private radio licenses are recorded at cost and amortized over twenty
      years. Interest costs incurred on borrowings throughout the period
      during which the certain FCC licenses are being readied for use are
      capitalized and amortized over the life of the license once the market
      to which the license pertains becomes commercial. Interest capitalized
      amounted to $4.6 million and $3.9 million in 1997 and 1996,
      respectively. The factors considered by management in performing this
      assessment include current operating results, trends and prospects as
      well as the effects of obsolescence, demand, competition and other
      economic factors.

      Foreign Currency Translation

      For international operations, assets and liabilities are translated at
      year-end exchange rates and income statement items are translated at
      average exchange rates for the period. Resulting translation adjustments
      are recorded as a separate component of shareholders' equity.
      Transaction gains and losses are recognized in the period incurred.

      Engineering and Development

      Engineering and development expenditures are expensed as incurred. All
      expenses relating to engineering and development ventures are recorded,
      net of grants, as engineering and development expense. Grants are
      recorded once the Company receives approval reflecting the fact that all
      terms and conditions relating to the expenditures have been met.

      Taxes on Income

      The Company provides for deferred taxes using the liability method
      whereby deferred tax assets are recognized for deductible temporary
      differences and operating loss carryforwards and deferred liabilities
      are recognized for taxable temporary differences. Temporary differences
      are the differences between the reported amounts of assets and
      liabilities and their tax bases. Deferred tax assets are reduced by a
      valuation allowance when, in the opinion of management, it is more
      likely than not that the deferred tax asset will not be realized.

      The Company does not provide for taxes which would be payable if
      undistributed earnings of its foreign subsidiaries were remitted because
      the Company considers these earnings to be permanently invested in these
      operations. Such amount of undistributed earnings is not significant at
      December 31, 1997.

      Earnings Per Share

      In February 1997, the FASB issued SFAS No. 128, "Earnings Per Share"
      ("SFAS 128"). SFAS 128 simplifies the standards for computing earnings
      per share and is effective for financial statements for both interim and
      annual periods ending after December 15, 1997. Basic earnings/loss per
      share is computed by dividing the net loss, after preferred stock
      dividend requirements, by the weighted average number of common shares
      outstanding during the year. In determining diluted EPS, Common stock 
      equivalents are excluded since the effect would be anti-dilutive.

      Recently Issued Accounting Pronouncements

      In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
      Income" ("SFAS No. 130"). SFAS No. 130 establishes standards for
      reporting and display of comprehensive income and its components in the
      financial statements. SFAS No. 130 is effective for fiscal years
      beginning after December 15, 1997. Reclassification of financial
      statements for earlier periods provided for comparative purposes is
      required. The Company is in the process of determining its preferred
      format. The adoption of SFAS No. 130 will have no impact on the
      Company's consolidated results of operations, financial position or cash
      flows.

      In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments
      of an Enterprise and Related Information" ("SFAS No. 131"). SFAS No. 131
      establishes standards for the way that public business enterprises
      report information about operating segments in annual financial
      statements and requires that those enterprises report selected
      information about operating segments in interim financial reports issued
      to shareholders. It also establishes standards for related disclosures
      about products and services, geographic areas and major customers. SFAS
      No. 131 is effective for financial statements for fiscal years beginning
      after December 15, 1997. Financial statement disclosures for prior
      periods are required to be restated. The adoption of SFAS No. 131 will
      have no impact on the Company's consolidated results of operations,
      financial position or cash flows; although it may impact the disclosure
      of reportable segment data. The Company is currently assessing the
      disclosure requirements.

2.    Disposed of Operations and Segments and Acquisitions:

      Discontinuation of Communication Products Segment / Sale of  BCI

      On November 26, 1997, the Company disposed of its communication products
      segment with the sale of its 64% interest in BCI for $18.5 million in
      cash resulting in a gain of $3.8 million. In accordance with the
      Company's debt covenants, at December 31, 1997, $9.1 million of the
      proceeds were limited in the timing of their use and, subsequently,
      these proceeds were released. The Company has reclassified BCI in its
      financial statements and has accounted for it as discontinued
      operations. The net assets of the discontinued operations were $12.9
      million at December 31, 1996, principally consisting of $0.9 million in
      cash, $6.5 million in receivables, $6.5 million in inventory, goodwill of
      $8 million, $6.3 million in accounts payable and accrued expenses and $4.8
      million in notes payable to banks.

      In August 1995, the Company transferred its interest in Speech Design
      GmbH and Bogen Communications, Inc. to BCI in exchange for $7.0 million
      in cash, $3.0 million in convertible notes, approximately 64% of BCI's
      common shares and warrants to purchase 200,000 shares of BCI common
      stock. Effective January 1, 1996, the $3.0 million convertible notes
      were reduced and restructured to a $0.5 million non-convertible
      promissory note due July 1997. In connection with this restructuring,
      the Company was granted an option to purchase up to $3.0 million of the
      common stock of BCI at up to a 35% discount. This option expired on
      October 31, 1997.

      Assets Held For Sale

      In connection with its strategic initiative to focus its efforts on
      marketing Driver Logistic(TM) Systems in the United States, on December
      18, 1997, the Company entered into two definitive agreements with
      Telesystems International Wireless, Inc. ("Telesystems") and affiliates
      to sell the Company's interest in its German joint venture ("Terrafon")
      and the Company's wholly-owned subsidiary in the United Kingdom,
      National Band Three Ltd. ("NB3"). These transactions closed in February
      1998.

      The Company sold all of the issued and outstanding shares of capital
      stock of NB3, a wholly-owned subsidiary and provider of analog public
      access mobile radio ("PAMR") service in the United Kingdom, for
      approximately $82 million in cash. Five percent of the purchase price
      will be held in escrow to satisfy the Company's indemnity obligations,
      if any, under the agreement and will be released within six months after
      the closing of the transaction. NB3 assets and liabilities were
      reclassified and are considered an asset held for sale. The transaction
      resulted in a pre tax gain of approximately $60.2 million to the Company
      which will be recognized in the first quarter of 1998. At December 31,
      1997, the total assets and liabilities of NB3 were $33.8 million and
      $10.5 million, respectively. Assets principally included approximately
      $4.5 million in cash, $3.2 million in accounts receivable, $5.2 million
      in goodwill and $18.5 million in property, plant and equipment.
      Liabilities consisted principally of accounts payable and accrued
      expenses incurred in the ordinary course of business.

      The Company sold its interest in Terrafon, the Company's 50/50 joint
      venture in Germany, which was formed through the merger of the Company's
      German networks with RWE Telliance A.G. ("RWE"), a mobile radio network
      in December 1996, for DM7 million (approximately $3.9 million) in cash.
      The investment in Terrafon at December 31, 1997 is presented as an asset
      held for sale and, as such, the Company reduced the carrying value of
      the investment to fair market value. Accordingly, the Company recognized
      a loss of $12.9 million on the investment balance of $18.0 million. The
      loss is included in equity in loss of subsidiaries. DM0.5 million of the
      purchase price is currently being held in escrow to satisfy the
      Company's indemnity obligations, if any, under the agreement and will be
      released within fifteen months after the closing of the transaction.

      Acquisitions

      During 1997, the Company issued approximately 57,000 shares of common
      stock to purchase a minority interest in the Company's subsidiary Geotek
      Technologies Israel ("GTI-Israel"). The shares were valued at $265,000.
      In July 1996, in a private transaction, the Company issued a Convertible
      Promissory Note ("Promissory Note") in the amount of $800,000 due
      December 31, 1996 in exchange for shares, held by a minority
      shareholder, in GTI-Israel. In October 1996, the holder converted the
      Promissory Note and accrued interest into approximately 102,000 shares
      of the Company's common stock. As of December 31, 1997, the Company owns
      98% of GTI-Israel.

      The Company purchased the remaining 50% ownership interest in software
      developer M.I.S. Information Systems Holdings Ltd. ("MIS") effective
      July 1, 1996. MIS was formed in 1994 as a 50/50 joint venture between
      the Company and Decision Systems Israel Ltd. The remaining 50% interest
      was acquired for a $2.0 million promissory note which bears interest at
      8.25% per annum and is due July 1, 1998. The Company attributed the
      excess of consideration paid over the fair value of net the assets
      acquired, approximately $1.9 million, to an acquired engineering and
      development project and expensed this amount at the time of the purchase
      as the acquisition primarily related to ongoing software development

      projects in process. In February 1998, the Company entered into an
      agreement to repay the $2.0 million note plus accrued interest in shares
      of the Company common stock (see Notes 8 and 17).

      In January 1997, the Company adjusted inventory standard costs to more
      accurately reflect replacement value of finished goods.

4.    Investments in Affiliates:

      In July 1997, the Company entered into a joint venture agreement with
      two Canadian partners for the purpose of deploying FHMA(R) Networks in
      the provinces of Ontario, Quebec and British Columbia utilizing 900MHz
      licenses previously granted to Geotek Communications Canada Inc., a
      wholly-owned subsidiary of GeoNet Communications Canada Inc. ("GeoNet
      Canada") by Industry Canada, the regulatory agency responsible for
      spectrum allocation in Canada. The Company invested $2 million in GeoNet
      Canada and the two Canadian partners invested $1 million each for a
      total initial investment of $4 million. Additionally, the Company
      deposited $2.3 million in a restricted cash account as collateral for
      the Canadian partner's investment. The parties reserved the right to
      withdraw from the venture. In the first quarter of 1998, the partners
      notified the Company and subsequently withdrew from the joint venture.
      The investors were repaid their investment from the restricted cash
      account. The withdrawal of the Canadian partners resulted in the loss of
      the Canadian license although the Company may reapply for licenses at
      such time that the Company obtains sufficient financing to pursue the
      deployment of networks in Canada.

      In July 1997 and 1996, the Company contributed approximately $4.7
      million and $7.7 million, respectively, to Anam Telecommunications Co.
      Ltd. ("Anam Telecom") in which the Company holds a 21% interest,
      representing of the Company's portion of the capital requirements. Anam

      Telecom holds a license to operate a nationwide trunked radio system in
      Korea. Additionally, the Company paid the Korean Ministry of Information
      and Communications $1.8 million in 1996, representing the Company's
      portion of the fee for the Korean nationwide license. Interest costs
      incurred by the Company during the development period prior to Anam
      Telecom commencing commercial service were capitalized. The amount
      capitalized in 1997 and 1996 was approximately $1.4 million and $0.6
      million, respectively, and has been included in investments in
      affiliates. In October 1997, commercial service began. The costs for the
      capitalized interest and nationwide license are being amortized over a
      twenty year period which began in October 1997. Amortization expense for
      1997 was not material. At December 31, 1997, the Company's investment in
      Anam Telecom was approximately $13.6 million and equity in loss was
      approximately $2.4 million in 1997 and was not material in 1996.

      As part of the joint venture agreement, in 1996, upon obtaining a
      national license in Korea, the Company granted the joint venture partner
      and other related parties options to purchase 800,000 shares of the
      Company's common stock for $10.00 per share. The Company estimated the
      fair value of the options granted at approximately $2.2 million. The
      Company recorded this amount as an additional investment in Anam Telecom
      and is amortizing this amount over a two year period.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

      In September 1996, the Company entered into an agreement with Anam
      Telecom pursuant to which the Company will provide Anam Telecom with up
      to $13.3 million ($10.5 million after the elimination of intercompany
      revenues) of 800 MHz infrastructure equipment. Additionally, the Company
      entered into a separate agreement to sell customer subscriber units to
      Anam Telecom. In connection with these agreements, the Company received
      advance payments of approximately $9.5 million in 1996 which were
      included in accrued liabilities. At December 31, 1997, the Company,
      after the elimination of inter-company revenues, recognized
      approximately $8.8 million on its sale of digital wireless
      infrastructure equipment to Anam Telecom, a related party, and no
      advance payment remained outstanding.

      During 1996, the Company contributed the net operating assets of their
      two wireless networks in Germany to a joint venture, Terrafon, with RWE
      and entered into an agreement in 1997 with Telesystems to sell its
      interest in Terrafon as described in Note 2. In March 1997, the Company
      contributed approximately $2.6 million to Terrafon, which represented
      the Company's portion of the estimated 1997 operating budget.

      The Company acquired, in August 1993, a 25% equity interest in Cumulous
      Communications Company ("Cumulous") for an aggregate consideration of
      $1.5 million. Cumulous is a provider of SMR services in the San Joaquin
      Valley of California. The Company's investment exceeds its share of the
      underlying net assets of Cumulous by approximately $940,000 which amount
      is being amortized over 20 years. The carrying value of this investment

      as of December 31, 1997 and 1996 was $1.0 million and $1.1 million,
      respectively.

(a)  In July 1995, the Company issued, in a private offering, $207.0 million
     aggregate principal amount at maturity of the Discount Notes due July 15,
     2005. Gross proceeds of the Discount Notes were approximately $100.0

     million. Interest accretes semi-annually at 15% until January 15, 2001 at
     which time the carrying value will equal the principal amount. The
     Discount Notes were issued with 6,210,000 detachable warrants ("the
     Warrants"). Each Warrant entitles the holder to purchase one share of the
     Company's common stock at an exercise price of $9.90 per share. The
     Warrants, which were valued at $29.2 million, were recorded as a
     reduction of the Discount Notes and are being accreted over the ten year
     life of the Discount Notes. The Discount Notes accrue interest until
     maturity at a rate of 15% per annum. Interest on the Discount Notes will
     be payable semi-annually, in cash, on July 15 and January 15, commencing
     January 15, 2001. The Discount Notes are fully and unconditionally
     guaranteed, jointly and severally on a senior basis, by certain
     subsidiaries of the Company.

     In August 1996, in connection with the original issuance of the Discount
     Notes, investors affiliated with George Soros purchased approximately
     $21.0 million principal amount of additional units consisting of 15%
     Senior Secured Discount Notes due 2005 and 621,000 ten year warrants to
     purchase shares of Company common stock at $9.90 per share. The warrants,
     which were valued at $2.9 million, were recorded as a reduction on the
     Discount Notes and are being accreted over the ten year life of the
     Discount Notes. Gross proceeds to the Company were approximately $10.0
     million, bringing total gross proceeds from the issuance of the Discount
     Notes to approximately $110.0 million.

     The Company recorded in other assets approximately $4.3 million of
     deferred financing costs relating to this transaction which are being
     amortized, using the interest method, over the ten year life of the
     Discount Notes. Accumulated amortization as of December 31, 1997 and 1996
     was approximately $1.1 million and $0.6 million, respectively.

     In accordance with the terms of the Indenture governing the Discount
     Notes, the proceeds from the sale of assets collateralizing the Discount
     Notes (See Note 2) are limited in their use (see Debt Compliance Matters
     below). In accordance with an amendment to the Indenture, the Company is
     required to use 20% of the net proceeds from the sale of its European
     Assets (estimated at $85 million) to tender the pro-rata share of the
     accreted value of the Discount Notes. At December 31, 1997, the Company
     has reclassified the estimated tender offer amount of $17.2 million to
     the current portion of long-term debt. Additionally, under the amendment
     to the Indenture, the Company granted the Discount Note holders a
     security interest in certain assets.

     In November 1995, the Company registered the Discount Notes and the
     Warrants through an exchange offer under the Securities Act of 1933, as
     amended.

(b)  In March 1996, the Company issued $75.0 million aggregate principal
     amount of Senior Subordinated Convertible Notes due 2001 ("Convertible
     Notes"). Each Convertible Note is in the principal amount of $1,000 and,
     beginning on March 5, 1997, are convertible by the holders into shares of

     the Company's common stock, par value $0.01, at a conversion price equal
     to $9.50 per share. Cash interest on the Convertible Notes accrues at a
     rate of 12% per annum and is payable semi-annually on each February 15
     and August 15. The Convertible Notes are unsecured senior subordinated
     obligations of the Company. Beginning October 1997, the Convertible Notes
     can be converted at the option of the Company if the closing price of the
     Company's common stock for 20 of the 30 trading days and for the five
     trading days before the conversion is at least $15.20 per share. The
     Company has reserved 7,894,737 shares of the Company's $0.01 par value
     Common Stock which are issuable upon conversion of the Convertible Notes.

     In connection with the issuance of the Convertible Notes, the Company
     incurred approximately $2.3 million in financing costs which have been
     recorded in other assets and are being amortized over the five year term
     of the

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     Convertible Notes. Accumulated amortization as of December 31, 1997 and
     1996 was approximately $0.8 and $0.4 million, respectively.

(c)  These notes were assumed in connection with the purchase of certain SMR
     licenses in various cities in the US. Certain analog SMR equipment as
     well as revenues generated by the systems is pledged as collateral for
     the notes.

(d)  In December 1995, the Company and HNS, the Company's strategic partner in
     the development of the Company's portable subscriber unit, entered into
     an agreement whereby HNS extended the Company a two year, $24.5 million
     line of credit for the Company to acquire additional 900 MHz spectrum in
     the United States. In October 1996, the Company borrowed $24.5 million
     under the line of credit agreement. Under the terms of the agreement, the
     two year loan bears interest at 12%, payable quarterly, and is
     convertible by the holder, beginning 181 days after drawdown, at the
     lower of 90% of the average sale price of the Company's common stock for
     the 10 days preceding conversion or $9.75. In connection with this
     agreement, the Company has reserved 16,333,333 shares of the Company's
     $.01 per value Common Stock which are issuable upon conversion of the
     note. The original $24.5 million loan agreement was collateralized by the
     pledge of the capital stock of the Company's subsidiary which holds the
     Company's Major Trading Area ("MTA") licenses. In conjunction with the
     amendment to the Indenture governing the Discount Notes, (see Debt
     Compliance Matters below) the MTA licenses were reallocated between the
     subsidiary pledged to HNS and the subsidiary pledged to the Discount Note
     Holders.

(e)  In April 1996, the Company and S-C Rig Investments - III, L.P. ("S-C
     Rig"), a significant stockholder of the Company and an investment group
     affiliated with George Soros, entered into a Senior Loan Agreement
     whereby S-C Rig made a $40.0 million unsecured credit facility ("S-C Rig
     Credit Facility") available to the Company beginning June 1996. In April

     1997, the Company and S-C Rig modified the terms of the S-C Rig Credit
     Facility. Under the modified terms, all of the borrowings are required to
     be made within three years from the initial establishment of the credit
     facility. The borrowings will accrue interest at a rate of 8% per annum
     and will mature in five years from the date of the final borrowings
     thereunder. The Company is obligated to pay S-C Rig a fee equal to 3% of
     each borrowing under the S-C Rig Credit Facility at the time of such
     borrowing. Borrowings under the S-C Rig Credit Facility constitute senior
     indebtedness of the Company.

     In connection with the establishment of the credit facility, the Company
     issued to S-C Rig a five year warrant ("S-C Rig Warrant") to purchase
     approximately 4.2 million shares of Common Stock (subject to adjustment
     in certain circumstances) at an exercise price of $9.50 per share
     (subject to adjustment in certain circumstances). With the modification
     of the S-C Rig Credit Facility, the exercise price of the warrants was
     lowered to $6.00 per share and the warrant termination date was extended
     from April 2001 to April 2003. This warrant is exercisable at any time
     during the warrant period. The S-C Rig Warrant, which was originally
     valued in 1996 at $13.4 million, was revalued in 1997 at $4.5 million due
     to the modification of terms. The $6.0 million excess of net book value
     of the S-C Rig Warrant over the new valuation was recorded by the Company
     in 1997 as a decrease in additional paid in capital. The S-C Rig Warrant
     is being amortized over the term of the underlying credit facility,
     approximately five years. In connection with the drawdown of $40.0
     million under the S-C Rig Credit Facility, the remaining valuation of the
     S-C Rig Warrants, $3.9 million was reclassified to long-term debt and is
     reflected as a discount on the issuance of loans made under the facility.

(f)  In September 1996, the Company, through its wholly owned subsidiary
     Geotek Financing Corporation ("GFC"), entered into a series of agreements
     with HNS under which HNS agreed to manufacture at least 50% of certain
     components utilized by the Company in its 900 MHz infrastructure
     equipment and to provide the Company with up to $100 million in vendor
     credit financing, the last $50 million of which is subject to the

                                    F - 22
<PAGE>

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     satisfaction of certain conditions. Under the terms of the vendor credit
     financing agreement, the Company will finance 90% of its purchases of
     infrastructure related equipment from HNS until June 1999. All borrowings
     made under the agreement bear interest at a rate of 11% per annum which
     is not payable until December 1999, unless there is an event of default,
     at which time interest would be payable quarterly. Beginning December
     1999, principal and interest are to be paid semi-annually in equal
     installments over a five year period. The HNS Vendor Credit Facility is
     collateralized by the pledge of the capital stock of the Company's
     subsidiary which holds certain of the Company's MTA licenses.

     In connection with the above agreement, the Company issued HNS seven year
     warrants ("HNS Warrants") to purchase 2,500,000 shares of the Company's

     common stock. The HNS Warrants allow HNS to purchase 1,000,000 shares at
     $8.625 per share, 1,000,000 shares at $10.78 per share, and 500,000
     shares at $12.94 per share. These warrants are exercisable at any time,
     and from time to time, after September 27, 1997. The HNS Warrants, which
     have been classified as debt issuance costs and were valued at
     approximately $8.7 million, were recorded as other assets and are being
     amortized over the life of the facility and the debt payback period,
     approximately seven years. Accumulated amortization as of December 31,
     1997 and 1996 was approximately $1.6 million and $0.3 million,
     respectively.

     Debt Compliance Matters

     The Discount Notes are collateralized by a pledge of substantially all
     subsidiary capital stock owned by the Company. In December 1997, the
     Indenture governing the Discount Notes was amended allowing the Company
     to utilize the proceeds of the sale of the stock of BCI and portions of
     the proceeds of the sale of the stock of NB3 and Terrafon for working
     capital purposes. Specifically, the amendment permits the Company's use
     of net proceeds from the sale of NB3 and Terrafon, approximately as $85
     million as follows: 20% to repay the Discount Notes; 40% for working
     capital; and 40% for replacement assets defined as qualifying capital
     expenditures. Additionally, the Company increased its ability to utilize
     the proceeds from future debt issuances for working capital by (i) $40
     million, including the proceeds from the sale of BCI; (ii) an additional
     $2.00 for every $1.00 of equity raised by the Company up to $40.0
     million; and (iii) an additional $1.00 for every $1.00 in equity raised
     thereafter up to a total of $30.0 million.

     The covenants place generally more stringent limitations, the most
     restrictive of which are related to making certain investments in assets
     other than telecommunication assets, incurring additional debt, use of
     proceeds from possible future asset sales, and paying dividends on common
     shares. There was no event of default at December 31, 1997. In the event
     that the Company does not obtain additional financing or successfully
     renegotiate the terms of certain indebtedness, it may be in default of
     certain covenants.

      income taxes for the years ended December 31, 1997, 1996, and 1995 is as

      The provision for income taxes, solely attributable to foreign taxes,
      consists of the following for the years ended December 31, 1997, 1996
      and 1995 (dollars in thousands):

                                            1997        1996        1995

      Included in the current foreign tax provision in 1996 and 1995 is
      $357,000 and $950,000, respectively, related to the utilization of
      pre-acquisition net operating losses of a subsidiary which had a full
      valuation allowance established at the time of the acquisition by the
      Company and has been recorded as a reduction to intangible assets. The
      pre-acquisition net operating loss was fully utilized in 1996. The
      Company has not provided deferred U.S. income taxes which would be
      payable if the undistributed earnings of its foreign subsidiaries, which
      totaled $3.5 million, $3.6 million and $2.1 million at December 31,
      1997, 1996 and 1995, respectively, were remitted because the Company
      considers these earnings to be permanently reinvested in these
      operations.

      The Company has established a valuation allowance substantially
      offsetting the tax benefit of current and long term deferred tax assets
      as it is more likely than not that the tax benefit will not be realized.
      The Company has domestic net operating loss carryforwards ("NOL") for
      tax purposes of approximately $301.1 million and $169.7 million as of
      December 31, 1997 and 1996, respectively, which expire between the years
      2001 through 2011. Additionally, the Company had foreign NOL
      carryforwards of approximately $7.1 million and $35.9 million in 1997
      and 1996, respectively. The NOL's are subject to certain limitations on
      their utilization as a result of various changes in control which have
      occurred.

      Rent expense included in continuing operations was $9.6 million, $7.7
      million, and $6.3 million in 1997, 1996 and 1995, respectively.

      Government Participation in Engineering and Development Project

      The Chief Scientist of the Israeli Ministry of Industry and Commerce
      ("Chief Scientist") has agreed to fund certain eligible expenditures
      related to the development of the digital wireless communication system
      by GTI-Israel. Funding received from the Chief Scientist is repayable
      without interest based on 3% of revenues generated by the product being
      developed by GTI-Israel up to 120% of the grant received which may be
      increased to 150% if certain manufacturing milestones are not met. Such
      participation amounted to $0.3 million and $5.9 million for 1996 and
      1995, respectively, and has been reported in the statement of operations
      as a reduction of engineering and development expenses. Accumulated
      grants under this program, subject to repayment under certain
      conditions, are $12.0 million.

      Manufacturing and Sales Commitments

      In 1994, the Company contracted with Mitsubishi Consumer Electronics of
      America ("MCEA") to manufacture mobile radios on behalf of the Company.
      This agreement was terminated by MCEA in 1998 and MCEA reserved any
      rights, if any, it had under the contract claiming defaults and
      deficiencies by the Company.

      In March 1995, the Company and HNS, a related party, formed a strategic
      partnership to develop a portable unit. Under the terms of the
      agreement, HNS and the Company will share equally in the cost of
      developing the portable unit. During 1995, the Company included as
      engineering and development expense approximately $6.0 million paid to
      HNS under the terms of this development contract. Additionally, during
      the year ended December 31, 1997, the Company accrued $3.2 million in
      engineering and development expense relative to final development costs
      under the contract. During 1996 the Company made advances on account of

      production of $11.5 million to HNS, which is included in Advances to
      Related Parties. The Company has included all advances made to HNS which
      will be applied against future purchases in advances to related parties.

      In June 1997, the Company entered into an agreement with HNS for HNS to
      produce a docking station for the Company's portable unit.

      In September 1996, in connection with the HNS Vendor Credit Facility,
      the Company entered into an

      agreement with HNS, whereby HNS will manufacture at least 50% of certain
      components utilized by the Company in its 900 MHz infrastructure
      equipment through June 1999. The Company made a 10% or approximately
      $0.9 million advance to HNS for production. At December 31, 1997, $7.3
      million in purchase orders were placed with HNS.

      In 1996, the Company entered into a manufacturing agreement with
      Farbell, whereby Farbell will produce Drive Station(TM) for the
      Company's digital wireless system. At December 31, 1997 and 1996, the
      Company placed $2.5 million and $2.2 million into a restricted cash
      account to fund these purchases.

      In 1996, the Company entered into an agreement with Anam Telecom (see
      Note 4) whereby the Company will provide the Company's digital wireless
      system infrastructure equipment and subscriber units to Anam Telecom. In
      connection with these agreements, the Company received advance payments
      of approximately $5.0 million and $9.5 million which is included in
      accrued expenses as of December 31, 1997 and 1996, respectively.

      Guarantees of Debt of a Subsidiary

      The Company has guaranteed the repayment of certain indebtedness of its
      subsidiary, GMSI, to its former owner in the amount of CDN $2.0 million
      (approximately $1.4 million).

      FCC Waiver

      As permitted by the FCC, the Company subsumed its Designated Frequency
      Area ("DFA") licenses which were acquired prior to the 1996 auctions
      with the Company's MTA licenses so that, together, they are regulated as
      a single MTA license. Under the terms of the MTA licenses the Company
      acquired during the auctions, a MTA will be "constructed' if one-third
      of the market's population is served within three years of the grant,
      August 12, 1999, and two-thirds of the population are served within five
      years of the grant, August 12, 2001. As an alternative, the Company may
      elect for the FCC to waive the requirements for August 12, 1999 and
      agree to provide substantial service to the MTA by August 12, 2001. At
      December 31, 1997, approximately $39.4 million of the Company's $72.7
      million (cost basis) of licenses were commercial.


      Litigation

      In June 1994, the Company filed a lawsuit against Harris Adacom
      Corporation B.V. ("Harris"), a Dutch Corporation, to enforce the
      Company's right to repayment of a $3.5 million loan made to Harris in
      January 1994. In or about May 1994, creditors placed Harris into
      bankruptcy. In response to the Company's lawsuit, Harris and its
      subsidiaries filed a lawsuit against the Company in the courts of the
      State of Israel requesting a declaratory judgment that the Company
      entered into a binding agreement for the purchase by the Company of a
      significant interest in certain wireless communication business assets
      owned by Adacom Technologies Ltd., ("ATL"), an affiliate of Harris and
      an Israeli publicly traded company, and subsequently breached such
      agreement. In July 1997, the plaintiffs filed a motion with the court
      seeking to amend the Statement of Claim to assert a claim for monetary
      damages of approximately $27 million arising out of the same
      transaction. This motion is pending. In addition, the plaintiffs are
      seeking to add Yaron Eitan, the Company's Chairman of the Board, and
      Yoram Bibring, who, prior to the Company's reorganization in December
      1997, was President and CEO of Geotek International Networks, Inc., as
      party defendants. The Company believes that the plaintiffs' claims and
      such actions are primarily an attempt to delay efforts to collect
      Harris's debt to the Company and the Company has meritorious defense.
      The Company intends to defend this action vigorously.

      The Company develops and utilizes technology for substantially all of
      the services and products it offers and intends to offer and has, from
      time to time, been the subject of infringement claims related thereto.
      It is often difficult to predict the outcome of such litigation and the
      amount of damages that may be awarded. The

      Company does not believe that any pending or threatened litigation
      related to the Company's technology or use thereof will have a material
      adverse effect on its business.

      The Company also is, from time to time, a party to litigation, which may
      or may not be covered by insurance, arising in the ordinary course of
      business. The Company does not believe that results of such litigation,
      even if the outcome were unfavorable to the Company, would have a material
      adverse effect on the financial position and results of operations.

11.   Redeemable Preferred Stock

      In December 1993, the Company issued to investors affiliated with George
      Soros, a related party, 444,445 shares of Series H Cumulative Redeemable
      Preferred Stock ("Series H Stock") at a price of $90 per share. The
      shares bear a dividend for five years, at a rate of five percent per
      year, payable quarterly. The shares are redeemable, at stated value, on

      October 31, 2000 only if the Company's common stock has not closed at an
      average price of $18 for any 20 consecutive trading days after the third
      anniversary of the date of issuance of the preferred shares. In the
      event that the shares are redeemed, the Company may elect to pay the
      redemption price in shares of its common stock, provided that the common
      shares will have an aggregate market value equal to 150% of the
      redemption value of the Series H shares being redeemed. The shares are
      convertible into common shares at any time at a ratio (adjusted for
      splits) of ten common shares for each preferred share. The Company has
      reserved 4,444,450 shares of its $.01 par value Common Stock issuable
      upon conversion of the Series H Stock. The holders of the Series H Stock
      are entitled to vote on all matters voted on by common shareholders as
      if the Series H Stock were converted to common stock. The Company has
      paid cash dividends of $2.0 million during each of the years ended
      December 31, 1997, 1996 and 1995.

      the $50,000 stated value per share plus any accrued or unpaid dividends
      at the date of conversion, by the lowest daily volume weighted averaged
      price of the Company's Common Stock during the four trading days
      immediately preceding conversion multiplied by the conversion factor
      (the conversion factor began at 100%, became 95% and 90% on June 29,
      1997 and December 31, 1997, respectively, and becomes 88% on June 29,
      1998). The holders could only convert up to a maximum of 20% prior to

      Series O Stock to convert additional shares of Series O Stock beyond the
      20% limitation prior to July 1, 1997, holders agreed to a higher
      conversion price than what otherwise would have been in effect, at the

(g)   The Company issued 500 shares of Series P Cumulative Convertible

      in either shares of the Company's Common Stock or cash at the rate of
      10% per annum (12% per annum after a dividend payment failure) at the

      plus any accrued or unpaid dividends at the date of conversion by the
      lowest daily volume weighted average price of the Company's Common Stock
      during the four trading days immediately preceding conversion multiplied
      by the conversion factor (this factor began at 100%, became 95% and 90%
      on June 1, 1997 and December 31, 1997, respectively, and will be 88% on
      June 29, 1998). However, the holder was only able to convert up to a
      maximum of 20% prior to June 30, 1997, an additional 30% prior to
      December 31, 1997 and will be able to convert an additional 30% prior to
      June 29, 1998 and the remainder thereafter. In connection with this

      transaction, the Company issued warrants to purchase 850,000 shares of
      the Company's Common Stock at $9.2625 per share (subject to adjustment
      in certain circumstances). The warrants are exercisable at any time, and

      dividends of approximately 398,000 shares of Common Stock with a value
      of approximately $1.5 million and 250 shares of Series P Stock,

      Company's Common Stock or cash at the rate of 10% per annum (12% per
      annum after a dividend payment failure) at the option of the Company.
      Currently, each share of Series Q Stock is convertible by the holder
      into the number of shares of the Company's Common Stock as obtained by
      dividing the $50,000 stated value per share plus any accrued or unpaid
      dividends at the date of conversion by the lowest daily volume weighted
      average price of the Company's Common Stock during the four trading days
      immediately preceding conversion multiplied by the conversion factor
      (this factor began at 100% and becomes 95% and 90% on January 1, 1998
      and April 1, 1998, respectively). However, the holder was only able to
      convert up to a maximum of 25% prior to January 1, 1998 and can convert
      an additional 25% prior to March 31, 1998, an additional 30% prior to
      June 30, 1998 and the remainder thereafter. In connection with this
      transaction, the Company issued warrants to purchase 1,800,000 shares of
      the Company's Common Stock at $8.00 per share (subject to adjustment in
      certain circumstances). The warrants are exercisable at any time, and
      from time to time, before February 10, 2001. During 1997, the Company
      paid dividends of approximately 423,000 shares of Common Stock with a
      value of approximately $1.2 million, 32 shares of Series Q Stock,

      Series Q Stock.

      A portion of the Series O Stock and Series Q Stock was exchanged for
      shares in the Company's Preferred Stock Series R ("Series R Stock") and
      Preferred Stock Series S ("Series S Stock") in February 1998 (See Note
      17). Additionally, a portion of Series O Stock, Series P Stock and
      Series Q Stock was converted subsequent to December 31, 1997 (see Note
      17).

      Common Stock

      In April 1996, the Company purchased 100% of the outstanding stock of
      MacDermott Communications, Inc., a private company whose only asset was

      an SMR License, for 190,988 shares of the Company's Common Stock. The
      value of the Common Stock issued was approximately $2.0 million. This
      amount was ascribed to the SMR license, which is included in intangible
      assets, and is being amortized over twenty years.

      The Company has reserved approximately 124.9 million shares of the
      Company's $.01 par value Common Stock issuable upon the conversion of
      redeemable preferred stocks; convertible preferred stock; exercise of
      warrants; and options and convertible indebtedness.

      Deemed Dividends and Interest

      The staff of the Securities and Exchange Commission clarified their
      position on accounting for convertible preferred stock and convertible
      debt containing a conversion feature with a stated discount to the
      market price of the Company's Common Stock at the time of conversion.
      With respect to convertible preferred stock, solely for the purposes of
      calculating earnings per share, the stated discount is amortized over
      the period from the date of issuance until the holder is permitted to
      convert and thus reduces the amount of income available to common
      stockholders. During the year ended December 31, 1997, the Company
      recognized approximately $5.2 million as a deemed dividend on Series O
      Stock, Series P Stock, and Series Q Stock which resulted in a $0.08
      increase in net loss applicable to common shares. As discussed in Note
      17, Series O Stock and Series Q Stock was exchanged for Series R Stock
      and Series S Stock which is convertible at a fixed cost greater than the
      market price at the time of the exchange. With respect to convertible
      debt, the stated discount is amortized as additional non-cash interest
      expense over the period from the date of issuance until the holder is
      permitted to convert. The Company recognized approximately $2.5 million
      in deemed interest on its $24.5 million convertible note with HNS during
      the year ended December 31, 1997.

      All warrants and options outlined above are vested upon issuance, except
      those issued in September 1996 pursuant the Company's vendor financing
      agreement with HNS which were exercisable beginning September 27, 1997.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

      Rig Credit Facility, and HNS vendor financing, the Company issued
      approximately 6.8 million, 1.0 million, 4.2 million and 2.5 million
      warrants to purchase Common Stock, respectively. In April 1997, the S-C
      Rig Credit Facility was modified and the warrant price was lowered from
      $9.50 to $6.00. In connection with the issuance of Series N Stock and
      Series O Stock, the Company issued 1.65 million and 1.7 million warrants
      at $11.00 and $8.00 respectively. In 1998, the warrants on Series O
      Stock were repriced (see Note 17).

b)    Preferred Stock - During 1997, in connection with the issuance of Series
      P Stock and Series Q Stock, the Company issued warrants to purchase .85
      million and 1.8 million shares of the Company's common stock at $9.2625
      and $8.00 per share, respectively (see Note 17 for discussion regarding
      the adjustment to warrant strike price).

c)    Vanguard Options - In 1994, the Company issued Vanguard options to
      purchase 10 million shares of the Company's Common Stock ("Series A
      Options") at an exercise price of $15.00 to $17.00 per share. In
      connection with the issuance of the Series L Stock to Vanguard and TDI,
      the terms of the Series A Options were modified whereby the total number
      of Series A Options were decreased from 10 million to 7 million and TDI
      held approximately 1.8 million of the Series A Options. In September
      1996, the Series A Options expired. Additionally, the Company's
      management consulting contract with Vanguard was terminated (See Note
      15).

d)    Other Warrants and Options - In July 1996, in accordance with the terms
      of the Company's joint venture agreement with Anam Industrial Co., Ltd.
      and other related agreements, which required the Company to grant options
      to its joint venture partner and other related parties upon receipt of a
      regional or national license in Korea (see Note 4), the Company granted
      options to purchase a total of 800,000 shares of the Company's common
      stock at $10 per share.

13.   Stock Compensation Plans

      The Company issues employee and director options to purchase shares of
      the Company's $.01 par value Common Stock under non-qualified stock
      option plans adopted in 1989 and 1994. The plans were combined and
      amended in July 1997. The amended 1994 plan allows the Company to issue
      10.0 million shares and to replenish the plan for options expired or
      canceled. Under the plan, employees and directors are granted ten year
      options to purchase shares of the Company's Common Stock at the greater
      of the closing price of the Company's Common Stock on the NASDAQ Stock
      Market(SM) on the date of grant or a price per share designated by the
      compensation committee of the Board of Directors. Employees vest over a
      period of three to five years from the date of grant.

      In September 1997, the Company offered a voluntary repricing plan to its
      employees and directors under which the strike price of outstanding
      grants would be reduced to $4.19. If the repricing was elected, any
      options vested would be required to revest annually in equal

      installments over a two year period commencing on the repricing date.
      The vesting period for unvested options, scheduled to vest in the
      subsequent 24 months, was extended six months. If an employee terminates
      prior to revesting, all terms, including price, revert back to the
      original terms. Approximately 360 employees and directors holding 3.5
      million options elected to reprice their options in accordance with the
      voluntary repricing plan. The repricing resulted in no compensation
      expense in the current year.

      The Company has adopted the disclosure only provision of SFAS No. 123,
      "Accounting for Stock-Based Compensation" ("SFAS No. 123") but applies
      the recognition criteria under Accounting Principles Board Opinion No.
      25 ("APB No. 25") and related interpretations in accounting for its
      plans. Compensation expense

      related to the Company's stock option activity in accordance with APB
      No. 25 was insignificant to the Company's results of operations in 1997,
      1996 and 1995. If the Company elected to recognize compensation costs
      for stock option plans based on the fair value at the date of grant for
      awards under these plans, consistent with methods prescribed by SFAS No.
      123, net loss and loss per share would have been the following pro forma
      amounts for the years ended December 31 (in thousands):

                               1997             1996            1995

          Pro forma             (3.76)       $   (2.58)       $  (1.80)

      The pro forma net loss and loss per share for 1996 and 1995 are not
      necessarily representative of the net loss and loss per share in future
      years because the 1996 and 1995 amounts do not include the incremental
      fair value of non-vested stock options granted prior to the adoption of
      SFAS No. 123.

      The fair value of the Company's stock options used to compute pro forma
      net income and loss per share disclosures is the estimated present value
      at grant date using the Black Scholes option-pricing model with the
      following assumptions for 1997:

                                          1997         1996          1995

14.   Fair Value of Financial Instruments

      The recorded amount of cash, cash equivalents, temporary investments and
      notes payable banks and other, approximates fair value due to the short
      term maturities of these assets and liabilities.

      Investments in affiliates are accounted for by the equity method and
      pertain to equity investments in privately held companies and joint
      ventures for which fair values are not readily available. The fair value
      of the Company's cash and cash equivalents, restricted cash, and notes
      payable are considered to be equal to their carrying amount as they are
      short-term in nature. The value of the Company's Convertible Notes and
      Discount Notes was determined using the market price of the debt
      instrument at December 31. The Company determines the fair value of its
      warrants using the Black Scholes option pricing model.

      In connection with the Company's HNS vendor financing agreement, the
      Company issued 2.5 million warrants to purchase shares of the Company's
      Common Stock. At December 31, 1997 and 1996, the HNS Warrants were
      carried at $7.2 million and $8.4 million, respectively, and have a fair
      value of $1.5 million and $5.7 million , respectively.

15.   Certain Other Related Party Transactions:

      In connection with the expiration of the Vanguard Options in September
      1996, the Company's five-year management consulting agreement with
      Vanguard, pursuant to which Vanguard provided operational and marketing
      support to the Company for an aggregate of 1.5 million shares of common
      stock, was terminated. For the years ended December 31, 1996 and 1995,
      Vanguard earned approximately 199,000 and 300,000 shares, respectively
      pursuant to this agreement. The fair market value of these shares were
      recorded as marketing expenses in 1996 and 1995 at approximately $2.1
      million and $2.4 million, respectively.

      The Company incurred expenses of $300,000 in 1997, 1996 and 1995,
      pursuant to its consulting agreement with a company affiliated with
      George Soros. Entities affiliated with George Soros also hold the
      Company's Series H Redeemable Preferred Shares, Series I Convertible
      Preferred Shares, $5.0 million of the Company's Series N Convertible
      Preferred Stock, Series P Convertible Preferred Stock, 10% of the

      GTI-Israel has entered into a subcontractor agreement with Rafael under
      which Rafael will partake in the development of the digital wireless
      network to be deployed by the Company and its subsidiaries in the United
      States and Korea. Engineering and development expense for the years
      ended December 31, 1997, 1996 and 1995 includes approximately $7.2
      million, $11.7 million, and $12.5 million, respectively, for research
      performed by Rafael under this agreement. Included in the 1995 expense
      is $2.0 million related to 250,000 shares of common stock issued to
      Rafael in connection with the development of the digital wireless
      network. GTI-Israel has also entered into agreements with Rafael under
      which Rafael manufactures the infrastructure equipment to be used by the
      Company in its U.S. network and for the sale of such equipment by the
      Company to third parties. Through December 31, 1997 and 1996, the
      Company had placed firm orders for equipment and engineering totaling
      $18.5 million and $24.0 million, respectively, and had made an advance
      payment (recorded in other current assets) of $2.5 million to Rafael
      under these orders as of December 31, 1996. At December 31, 1997, the
      Company had an $18.0 million payable to Rafael.

      In July 1996, the Company issued a Convertible Promissory Note in the
      amount of $0.8 million due December 31, 1996, for additional shares held

      by a minority shareholder, in the Company's subsidiary GTI-Israel (see
      Note 2). The Convertible Promissory Note was converted into 57,000
      shares of common stock during 1997.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

      In 1995, Rafael converted all the principal and interest issued to it by
      GTI-Israel under convertible debentures into shares of GTI-Israel
      representing its 38% interest in GTI-Israel. The Company issued to
      Rafael 1.8 million shares of unregistered Company Common Stock in
      exchange for RDC's shares of GTI-Israel. The Company valued the
      unregistered shares at $8.6 million and recorded the excess of the value
      of the shares over the fair value of the underlying assets of GTI-Israel
      of $7.8 million as goodwill. As part of the arrangement, Rafael was
      granted an option to purchase up to 10% of GTI-Israel in certain
      circumstances. Additionally, in October 1995, RDC purchased 338,000
      shares of Company common stock for $3.0 million.

      During the twelve months ended December 31, 1997, the Company provided
      certain senior executive officers $0.5 million in loans.

16.   Segment Information:

      Prior to November 1997, the Company's operations were classified into
      two business segments: wireless communications and communications
      products. The wireless communications group is engaged in the commercial
      roll-out and enhancement of its digital wireless network in the United
      States, principally through its subsidiary Geotek USA, Inc. ("Geotek
      USA"), formerly PowerSpectrum Inc., and GTI-Israel subsidiaries, sale of
      digital wireless infrastructure equipment, provision of mobile radio
      services in the United States (Geotek USA and MetroNet), analog mobile
      radio service in the United Kingdom (NB3) and Germany, prior to the sale
      of these activities (see Note 2) and the development of certain mobile
      data applications (GMSI and MIS). The development associated with the
      enhancement of the Company's digital wireless network is primarily
      taking place in Israel. GMSI is located in Canada and markets its
      products in Canada, the United States and the United Kingdom. In 1997,
      $9.1 million and $10.8 million of revenues for GTI - Israel were derived
      from its Korean customers, Anam Telecom, a related party, and Hyundai
      Electronics. These amounts represent a substantial portion of the work
      anticipated to be performed under the contracts with these customers.

      In November 1997, the Company disposed its communication products
      segment with the sale of BCI. BCI was engaged in the development,
      manufacturing and marketing of telephone and facsimile peripheral
      products and commercial audio and paging equipment in the United States
      and Germany (see Note 2).

      The Company is subject to the risks inherent in conducting business
      across national boundaries, including currency exchange rate
      fluctuations, international incidents, military outbreaks, economic
      downturns, government instability, nationalization of foreign assets,

      government protectionism and changes in governmental policy, any of
      which could adversely affect the Company's business in one or more of
      its international markets or in the U.S. In addition, the licensing and
      other operational risks attendant upon commencing and maintaining
      wireless communications networks in foreign countries are similar to
      those in the U.S., including availability of spectrum capacity and
      transmission sites, competition and government regulation. Development
      of the Company's business in international markets may impose a
      significant burden on the Company's financial, managerial and personnel
      resources. There can be no assurance that the Company will be successful
      in developing its business in any of these markets or that any such
      expansion of the Company's business will be profitable.

17.   Subsequent Events:

      As discussed in Note 2, the Company entered into two definitive
      agreements with Telesystems to sell the Company's interest in its German
      joint venture ("Terrafon") and the Company's wholly-owned subsidiary in
      the United Kingdom, National Band Three Ltd. ("NB3"). Both transactions
      were completed in February 1998.

      In February 1998, the Company completed an exchange of Series O Stock and
      Series Q Stock into new fixed price preferred instruments, Series R and
      Series S. Under the restructuring, the Series O Stock and Q Stock
      preferred holders have agreed to immediately convert approximately $12.4
      million of Series O Stock and Series Q Stock into common stock at $1.00
      per share and exchange a total of $22.4 million for new Series R Stock and
      S Stock ($15.9 million for Series R Stock and $6.5 million for Series S).
      The remaining $12.5 million will continue to be subject to a floating
      conversion rate and may be converted into common stock in increments over
      the next six months. Of the $12.5 million, $4.2 million has been converted
      since the exchange date leaving $8.3 million unconverted and subject to
      floating conversion rates. For each of the Series O Stock and Series Q
      Stock exchanged, the holders will receive 1.1111 shares of Series R Stock
      or 1 share of Series S Stock. The Company has also agreed to reset the
      exercise price of the approximately 3.2 million warrants issued in
      connection with the Series O Stock and Series Q Stock transactions at the
      same pricing terms of Series S Stock.

      The terms of the Series R Stock provide for the conversion at the option
      of the holder at any time into shares of the Company's Common Stock at a
      fixed price of $2.00 while Series S Stock provides for a conversion at
      $4.00 per share. Under the terms of Series S, if after six months the
      market price of the Company's common stock is less than $4.00 per share,
      the conversion price will adjust to $3.00 per share. If after twelve
      months, the market price is below $2.73 per share, the conversion price
      will adjust to 110% of the then prevailing market price. In addition,
      both Series R Stock and Series S Stock will continue to pay dividends
      quarterly at the 10% per annum rate that existed prior to the exchange.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


      The terms of the exchange require the Company to meet certain financing
      milestones, including the closing of the European asset sale mentioned
      above and the raising of an additional $50 million in financing by
      September 15, 1998 of which $25 million must be raised before May 15, 1998
      and which can immediately be applied for general working capital purposes.
      In addition, the Company must enter into agreements to exchange the
      remaining Series P preferred stock, currently with a floating conversion
      rate, into a fixed rate instrument or, alternatively, push back the right
      to convert the Series P until September 1998. Currently, Series P may be
      converted beginning in June 1998. In the event any of these milestones are
      not met, the investors will have the right to exchange the Series R Stock
      and Series S Stock for securities with a floating conversion rate. The
      Series R Stock and Series S Stock investors will also be given the
      opportunity to participate in new offerings of the Company's securities
      issued in connection with new financing.

      During the months of January and February 1998, shareholders of Series O 
      Stock converted 418 shares, valued at $20.9 million, into 24,807,144 
      shares of common stock, excluding accrued dividends; shareholders of 
      Series P Stock converted 150 shares valued at $7.5 million into 
      7,083,000 shares of common stock, excluding accrued dividends; 
      shareholders of Series Q Stock converted 68 shares valued at $3.4 million
      into 3,419,000 shares of common stock, excluding accrued dividends.

      In January 1998, the Company repaid the initial investors in its joint
      venture in Canada upon their request to terminate the joint venture (see
      Note 4).

      In February, 1998, the Company entered into an agreement to repay the
      $2.0 million note payable due July 1, 1998 plus accrued interest in
      shares of the Company's Common Stock based upon the stock price at the
      time the shares are registered.

19.   Condensed Consolidating Financial Information For Guarantors ("Guarantor
      Information"):

      In July and August 1995, the Company issued, in a private offering,
      $227.7 million aggregate principal amount at maturity of 15% Discount
      Notes due July 15, 2005 ("the Discount Notes"). In connection with the
      Discount Note offering, the Company's wholly-owned U.S. Domestic
      Subsidiaries, including Geotek USA, formerly PowerSpectrum Inc., and its
      Subsidiaries, (collectively referred to as the "Guarantor Subsidiaries")
      fully and unconditionally guarantee such Discount Notes jointly and
      severally. The Guarantor Subsidiaries are wholly owned by the Company.
      In addition, the Discount Notes are collateralized by a pledge of the
      capital stock owned by the Company in NB3, Geotek USA, Inc. and
      Subsidiaries, MetroNet Systems, Inc., Geotek

      GmbH Holding Corporation and BCI. As discussed in Note 2, the Company
      entered into agreements to sell NB3 and BCI.


      The Guarantor Information of Geotek Communications, Inc. and
      Subsidiaries has been presented on pages F-42 through F-49 in order to
      present the Guarantor Subsidiaries pursuant to the Guarantor
      relationship. The Guarantor Information is presented as management does
      not believe that separate financial statements of the Guarantor
      Subsidiaries would be meaningful. This Guarantor Information should be
      read in conjunction with the Consolidated Financial Statements. The
      Discount Notes include covenants that place restrictions on the Company
      primarily related to making certain investments, permitting liens,
      paying dividends and incurring additional debt.

      Notes to Guarantor Information:

      Basis of Presentation - To conform with the terms and conditions of the
      Notes, the condensed consolidating financial information of the
      Guarantor Subsidiaries are presented on the following basis:

    (1) Geotek Communications, Inc.  -Investments in consolidated subsidiaries
        (Parent Company)             are accounted for by the Parent Company
                                     on the cost basis for purposes of the
                                     Guarantor Information. Operating results
                                     of Subsidiaries are therefore not
                                     reflected in the Parent's investment
                                     accounts or earnings.

    (2) Guarantor Subsidiaries       -For purposes of the Guarantor
                                     Information, Guarantor Subsidiaries
                                     includes all U.S. wireless subsidiaries
                                     of Geotek USA combined with Geotek
                                     Financing Corporation, Geotek License
                                     Holding Inc., MetroNet Systems, Inc. and
                                     ANSA Communications, Inc., all direct
                                     wholly owned subsidiaries of the Parent
                                     Company. For purposes of the Guarantor
                                     Information, Geotek USA does not contain
                                     the consolidated financial statements of
                                     GTI - Israel, subsidiary of Geotek USA,
                                     since GTI - Israel is not a Guarantor
                                     Subsidiary. Such statements of GTI -
                                     Israel are included with Non-Guarantor
                                     Subsidiaries.

    (3) Non-Guarantor Subsidiaries   -This includes the Company's subsidiaries
                                     that are not Guarantor Subsidiaries,
                                     principally GTI - Israel, and NB3 which
                                     at December 31, 1997 was reclassified to
                                     assets held for sale.

    (4) Reclassifications and        -Certain reclassifications were made to
        Eliminations                 conform all of the Guarantor Information
                                     to the financial presentation of the
                                     Company's consolidated financial
                                     statements. The principal elimination
                                     entries eliminate investments in

                                     subsidiaries and intercompany balances
                                     and transactions.

NATIONAL BAND THREE LIMITED

Directors' report

for the year ended 31 December 1997

The directors present their report and the audited financial statements for the
year ended 31 December 1997.

Principal activities

The profit and loss account for the year is set out on page F- 57.

The principal activity of the company is the operation of regional and national
mobile communications networks, under licences granted by the Department of
Trade and Industry under the Telecommunications Act 1984 and the Wireless
Telegraphy Act 1949 and the marketing and sale of products and services for use
on the networks.

Review of business and future developments

During the year the company continued the operation of the networks and invested
in and strengthened its sales and marketing capability. This helped the
continued growth in the subscriber base during the year and provided new
products and services. Both the level of business and the year end financial
position were satisfactory, and the directors expect the level of activity to
continue for the foreseeable future.

Dividends

The directors do not recommend the payment of a dividend. The profit for the
period ?1,248,000 (1996: ?2,490,000) has been taken to reserves.

Post balance sheet event

In December the parent company, Geotek Inc (formerly Geotek Industries, Inc)
entered into an agreement to sell the entire share capital of the company to an
indirect, wholly-owned subsidiary of Telesystem International Wireless Inc. This
transaction was completed on 12 February 1998.

Research and development activities

During the year the company continued with the development of the digital
business and data products for use on the analogue networks.


Changes in fixed assets

The movements in fixed assets during the year are set out in note 9 to the
financial statements.

Report of the auditors to the members of
NATIONAL BAND THREE LIMITED

We have audited the financial statements on pages F - 57 to  F- 72.

Respective responsibilities of directors and auditors

As described on page F - 53 the company's directors are responsible for the
preparation of financial statements. It is our responsibility to form an
independent opinion, based on our audit, on those statements and to report our
opinion to you.

Basis of opinion

We conducted our audit in accordance with Auditing Standards issued by the
Auditing Practices Board. An audit includes examination, on a test basis, of
evidence relevant to the amounts and disclosures in the financial statements. It
also includes an assessment of the significant estimates and judgements made by
the directors in the preparation of the financial statements, and of whether the
accounting policies are appropriate to the company's circumstances, consistently
applied and adequately disclosed.

We planned and performed our audit so as to obtain all the information and
explanations which we considered necessary in order to provide us with
sufficient evidence to give reasonable assurance that the financial statements
are free from material misstatement, whether caused by fraud or other
irregularity or error. In forming our opinion we also evaluated the overall
adequacy of the presentation of information in the financial statements.

Opinion


In our opinion the financial statements give a true and fair view of the state
of the company's affairs at 31 December 1997 and of its profit and cash flows
for the year then ended and have been properly prepared in accordance with the
Companies Act 1985.

Notes to the financial statements
for the year ended 31 December 1997

1        Principal accounting policies

The financial statements have been prepared in accordance with applicable
Accounting Standards in the United Kingdom. A summary of the more important
accounting policies, which have been applied consistently, is set out below.

Basis of accounting

The financial statements are prepared in accordance with the historical cost
convention.

Goodwill

Goodwill arising on the acquisition of businesses is written off directly to an
unrealised goodwill reserve. It is amortised to the profit and loss account
reserve over five years, the directors' estimate of its useful economic life.

Tangible fixed assets

The cost of tangible fixed assets is their purchase cost, together with any
incidental expenses of acquisition.

Depreciation is calculated so as to write off the cost of tangible fixed assets,
less their estimated residual values, on a straight line basis over the expected
useful economic lives of the assets concerned.
The estimated useful lives used for this purpose are:


Short term leasehold improvements                Over the term of the lease
Plant and machinery                              Between three and ten years
Fixtures and fittings                            Between three and five years
Motor vehicles                                   Four years

No depreciation is charged on assets in the course of construction.

Stocks

Stocks are stated at the lower of cost and net realisable value. Provision is
made where necessary for obsolete, slow moving and defective stocks.

Turnover

Turnover, which excludes value added tax, represents the invoiced value of goods
and services supplied.

Operating leases

Costs in respect of operating leases are charged on a straight line basis over
the lease term.

Deferred taxation

Provision is made for deferred taxation, using the liability method, on all
material timing differences to the extent that it is probable that a liability
or asset will crystallise.

Pension costs

The company operates a "money purchase" pension scheme for the benefit of its
employees.

The company provides no other post retirement benefits to its employees.

Related party transactions

The company has taken advantage of the exemptions under Financial Reporting
Standard 8 not to disclose any transactions with entities that are part of the
group qualifying as related parties.

2        Turnover

Turnover consists entirely of sales in one class of business made in the United
Kingdom.

Directors' bonus provisions

A provision of 160,000 (1996: 80,000) has been made in these financial
statements in respect of bonus payments which may be made to the directors at
the company's discretion in respect of their performance during 1997.

Under a bonus scheme implemented in 1997, a bonus is payable to directors during
the period of the development of the proposed digital business. In the event of
a change in ownership of the company these bonuses crystallise in full. As a
result of the change of ownership referred to in note 20, 442,000 including
national insurance contributions was paid by Geotek Inc directly to the
directors after the year end.

23       Summary of differences between UK GAAP and US GAAP


         These financial statements on pages 1 to 17 are prepared in British
         pounds and presented in accordance with UK GAAP which differs in
         certain significant respects from US GAAP. These differences, which
         have a significant effect on consolidated net income and shareholders'
         equity, are discussed and quantified in a table of adjustments below.
         While this is not a comprehensive summary of all differences between UK
         GAAP and US GAAP, other differences are immaterial.

                  Significant differences between UK GAAP and US GAAP

         (a)      Deferred income taxes

                  Under UK GAAP, deferred taxes are only provided on timing
                  differences where it is considered probable that such taxes
                  will become payable in the foreseeable future. Under SFAS No
                  109, "Accounting for Income Taxes", US GAAP requires deferred
                  taxes to be provided in full under the liability method. There
                  is no net adjustment recorded to the deferred income tax
                  accounts for them to comply with US GAAP. Taxes on income
                  presented in 1996 reflect the utilisation of 630,000
                  pre-acquisition net operating loss, which had a full valuation
                  allowance established at the time of acquisition by the
                  company. The utilisation of this net operating loss has been
                  recorded in 1995 as a reduction to intangible assets. In 1997
                  full provision has been made for deferred taxation in the UK
                  financial statements.

         (b)      Goodwill

                  Under UK GAAP, the company eliminates goodwill against
                  reserves in the year in which it arises. US GAAP requires that
                  goodwill is capitalised and amortised through the income
                  statement over the estimated period of benefit. Additionally,
                  under applicable rules of "push-down accounting" goodwill
                  associated with the parent company's acquisition of the
                  company was "pushed-down" onto the books of the company at the
                  time of the acquisition. The parent company's policy is to
                  amortise goodwill on a straight line basis over 20 years.
                  Amortisation expense relating to goodwill was 200,000 and
                  227,000 for 31 December 1997 and 1996 respectively. The
                  carrying value of goodwill at 31 December 1997 after the
                  adjustment for utilisation of pre-acquisition net operating
                  loss (see (a)) and amortisation was 3,553,000.

         (c)      Statements of cash flows

                  The company prepares its consolidated statements of cash flows
                  under United Kingdom Financial Reporting Standard No 1, "Cash
                  Flow Statements" ("FRS1"). Its objectives and principles are
                  similar to those set out in the US Statement of Financial
                  Accounting Standards No 95, "Statement of Cash Flows"
                  ("SFAS95"). The principal differences between the standards
                  relate to classification. Under FRS1, the company presents its
                  cash flows as (a) operating activities; (b) returns on
                  investments and servicing of finance; (c) taxation; (d)
                  investing activities; and (e) financing activities. SFAS95
                  requires only three categories of cash flow activity; (a)
                  operating; (b) investing; and (c) financing. Cash flows from
                  taxation and returns on investments and servicing of finance
                  shown under FRS1 would be included as operating activities in
                  SFAS95.

                  (whether by amendment, renewal, substitution, replacement,
                  extension or refunding) Indebtedness (plus reasonable fees and
                  expenses directly associated with such financing) of such
                  Subsidiary, in each case other than Indebtedness refinanced,
                  redeemed or retired under clause (j), (k), (m), (n) or (o) of
                  this Section 4.08; provided, however, that (A) the principal
                  amount of Indebtedness incurred pursuant to this clause (p)
                  (or, if such Indebtedness provides for an amount less than the
                  principal amount thereof to be due and payable upon a
                  declaration of acceleration of the maturity thereof, the
                  original issue price of such Indebtedness) shall not exceed
                  the sum of the principal amount of Indebtedness so refinanced,
                  plus the amount of any premium required to be paid in
                  connection with such refinancing pursuant to the terms of such
                  Indebtedness or the amount of any premium reasonably
                  determined by the Board of Directors as necessary to
                  accomplish such refinancing by means of a tender offer or
                  privately negotiated purchase, plus the amount of expenses in
                  connection therewith and (B) in the case of Indebtedness
                  incurred by the Company pursuant to this clause (p) to
                  refinance Indebtedness subordinated in right of payment to the
                  Securities, such Indebtedness (I) has an Average Life to
                  Stated Maturity equal to or greater than the remaining Average
                  Life to Stated Maturity of the Indebtedness being refinanced
                  and (II) is subordinated to the Securities in the same manner
                  and to the same extent that the Indebtedness being refinanced
                  is subordinated to the Securities.

                  For purposes of determining compliance with this Section 4.08,
                  in the event that an item of Indebtedness meets the criteria
                  of more than one of the types of Indebtedness described in the
                  above clauses, the Company in its sole discretion, 

                                      6

<PAGE>

                  shall classify such item of Indebtedness and only shall be 
                  required to include the amount and type of such Indebtedness 
                  in one of such clauses.

Each reference in the Indenture to Section 4.08(n) is hereby amended to refer to
Section 4.08(p).

                           (b) Section 4.08 of the Indenture is hereby further 
amended to add the following clauses after clause (m) and before clause (p):

                           (n) unsecured Indebtedness of the Company or any
                  Subsidiary of the Company, in addition to that described in
                  clauses (a) through (m) above and clause (o) below, in an
                  aggregate principal amount outstanding at any time not
                  exceeding (i) $40,000,000 (less the amount of the Bogen Sale
                  Reinvestment Credit, if any, that is included in the Working
                  Capital Share of the Net Cash Proceeds from a Permitted

                  Foreign Asset Sale), minus (ii) the Working Capital Proceeds
                  from all Permitted Asset Sales occurring after November 1,
                  1997;

                           (o) unsecured Indebtedness of the Company or any
                  Subsidiary of the Company, in addition to that described in
                  clauses (a) through (n) above, in an aggregate principal
                  amount outstanding at any time not exceeding (i) two times the
                  net cash proceeds received by the Company from the issuance
                  and sale of Capital Stock (other than Redeemable Capital
                  Stock) by the Company or any of its Subsidiaries after
                  November 1, 1997, provided that the aggregate principal amount
                  of Indebtedness permitted by this clause (i) shall not exceed
                  $40,000,000, plus (ii) the net cash proceeds received by the
                  Company from the issuance and sale of Capital Stock (other
                  than Redeemable Capital Stock) by the Company or any of its
                  Subsidiaries after November 1, 1997 in excess of the amount of
                  cash proceeds utilized for purposes of incurring Indebtedness
                  permitted by clause (i) above, provided that the aggregate
                  principal amount of Indebtedness permitted by this clause (ii)
                  shall not exceed $30,000,000; provided, however, that if the
                  Capital Stock referred to in clause (i) or (ii) above is
                  issued by a Subsidiary of the Company, then any Indebtedness
                  based on the issuance of such Capital Stock shall be incurred
                  only by such Subsidiary and its direct and indirect
                  subsidiaries and not by the Company or any of its other
                  Subsidiaries;

                  5. Asset Sales.

                           (a) Section 4.12(a) of the Indenture is hereby 
amended and restated in its entirety to read as follows:

                           (a) (i) The Company will not, and will not permit any
                  of its Subsidiaries to, make any Asset Sale (including without
                  limitation a Permitted Asset Sale) unless (A) the Company or
                  such Subsidiary, as the case may be, receives consideration at
                  the time of such Asset Sale at least equal to the Fair Market
                  Value of the shares or assets sold or otherwise disposed of,
                  and (B) at least 85% of such consideration consists of cash or
                  Cash Equivalents or the assumption of Indebtedness of the
                  Company or such Subsidiary or other obligations relating to
                  such assets ("Assumed Obligations") and release from all
                  liability on such Assumed Obligations, unless, in the case of
                  clause (B), the remainder of such consideration consists of
                  (x) property or assets that will be owned by the Company or a
                  Subsidiary of the Company and are to be used in a
                  telecommunications business or related activities or services
                  that thereafter will be conducted by the Company or such
                  Subsidiary or (y) Capital Stock or other securities issued by

                  a party to the transaction or an Affiliate thereof, which
                  Capital Stock or other securities are freely tradeable and
                  which are sold for cash within 90 days of the consummation of
                  the Asset Sale in connection with which they were acquired,
                  provided that any such cash (net of any expenses related to
                  such sale or provisions for taxes payable as a result thereof)
                  shall constitute Net Cash Proceeds from the Asset Sale for
                  purposes of this Indenture (including without limitation
                  Section 10.08).

                                    (ii) The Company or its Subsidiary, as the
                  case may be, may, within 180 days of an Asset Sale, apply the
                  Net Cash Proceeds therefrom (or enter into a binding agreement
                  within such 180-day period to apply such Net Cash Proceeds
                  within 45 days of the date of such agreement) to (A) an
                  investment in properties and assets that replace the
                  properties and assets that were the subject of such Asset Sale
                  or in properties and assets that will be used in the business
                  of the Company and its Subsidiaries existing on the Issue Date
                  or in businesses reasonably related thereto ("Replacement
                  Assets") or (B) in the case of an Asset Sale by a Subsidiary
                  of the Company, the repayment of any Indebtedness of such
                  Subsidiary; provided, however, that so long as no Default or
                  Event of Default has occurred and is continuing, 

                                      8

<PAGE>

               the Company or such Subsidiary, as the case may be, may apply any
               Working Capital Proceeds received from a Permitted Asset Sale to
               the working capital needs and general corporate purposes of the
               Company or any Subsidiary of the Company. Any Net Cash Proceeds
               from any Asset Sale (other than Working Capital Proceeds from a
               Permitted Asset Sale) that are not invested in Replacement Assets
               (or in the case of an Asset Sale by a Subsidiary of the Company
               used to repay Indebtedness of such Subsidiary) within the 180-day
               period described above shall constitute "Excess Proceeds" subject
               to disposition as provided in Section 4.12(b). Notwithstanding
               the foregoing, the application of the Bogen Sale Proceeds shall
               be governed by Section 4.20 and the application of the Net Cash
               Proceeds of a Permitted Foreign Asset Sale or a Collateral Sale
               (other than the Bogen Sale) shall be governed by Section 10.08.

                                    (iii) The Company will not, and will not
                  permit any of its Subsidiaries to, make any Permitted Asset
                  Sale, a Permitted Foreign Asset Sale or a Collateral Sale if a
                  Default or an Event of Default has occurred and is continuing.

                  6. Subsidiary Guarantees. Sections 4.18(c) and (d) of the
Indenture are hereby amended and restated in their entirety to read as follows:

                           (c) To the extent that, after the date of this
                  Indenture, the Company establishes or acquires any additional

                  wholly owned direct and indirect subsidiaries which are
                  organized under the laws of a state of the United States or
                  the District of Columbia and which do business in the United
                  States, the Company shall promptly, but in no case later than
                  30 days after the date of such establishment or acquisition,
                  cause each such subsidiary to jointly and severally guarantee
                  the obligations of the Company under the Securities, this
                  Indenture, the Pledge Agreements, the Note Pledge Agreements,
                  the Security Agreements and any other security arrangements
                  pursuant to a Guarantee in form and substance satisfactory to
                  the Trustee, to the fullest extent provided herein and shall
                  be accompanied by an Opinion of Counsel as to the
                  enforceability thereof and such other matters as the Trustee
                  may reasonably request. Notwithstanding the foregoing, no
                  subsidiary of the Company (other than the Pledged Companies as
                  defined in the U.S. Pledge Agreement and their direct and
                  indirect Subsidiaries) shall be required to guarantee any of
                  the above-referenced 

                                      9

<PAGE>

                  obligations if the only material assets of such subsidiary
                  consist of Licenses and rights related thereto (including
                  rights under license agreements with respect to such Licenses)
                  and if all of the Capital Stock of such subsidiary is pledged
                  to secure Indebtedness (other than Indebtedness in respect of
                  the Securities) permitted to be incurred by the Company or one
                  of its Subsidiaries hereunder (an "Exempt Subsidiary").

                           (d) To the extent that any wholly-owned subsidiary of
                  the Company that is organized under the laws of a state of the
                  United States or the District of Columbia (other than Cumulous
                  if it is not a Guarantor and other than an Exempt Subsidiary)
                  is not required to execute and deliver a Guarantee as
                  contemplated above, the Company hereby covenants that such
                  subsidiary shall not engage in any business activities in the
                  United States or hold any License. To the extent any such
                  subsidiary engages in such business activities or holds any
                  License at such time, the Company shall cause such business
                  activities to be ceased promptly and/or such Licenses to be
                  transferred (and the Company will use its best efforts to
                  cause any Licenses to be so transferred), as soon as
                  practicable to a Guarantor.

                  7. Bogen Sale Proceeds; Restrictions Pending License
Reallocation; Quarterly Compliance Certificate. Article Four of the Indenture is
hereby further amended to add the following sections after Section 4.19:

                  4.20  Application of Bogen Sale Proceeds.

                           (a) Upon the First Amendment to this Indenture
                  becoming effective, and so long as no Default or Event of

                  Default has occurred and is continuing, the Company may use up
                  to $5,000,000 of the Bogen Sale Proceeds for the working
                  capital needs and general corporate purposes of the Company
                  and its Subsidiaries. The balance of the Bogen Sale Proceeds
                  shall be deposited in the Custody Account and shall be applied
                  as provided in this Section 4.20.

                           (b) Upon delivery to the Trustee of an Officers'
                  Certificate that (i) the License Reallocation has been
                  approved by an order of the FCC (the finality of which is
                  subject to the expiration of a 45-day period for objections or
                  appeals), (ii) Hughes Network Systems, Inc. has consented to
                  the License Reallocation, and (iii) no person has objected to
                  the License Reallocation 

                                      10

<PAGE>

                  or attempted to intervene in the FCC proceedings relating to
                  the License Reallocation, the Company may withdraw from the
                  Custody Account up to an additional $5,000,000 of the Bogen
                  Sale Proceeds for the working capital needs and general
                  corporate purposes of the Company and its Subsidiaries.

                           (c) On or after the later of (i) February 1, 1998,
                  and (ii) the delivery of the Officers' Certificate referred to
                  in Section 4.20(b), the Company may withdraw from the Custody
                  Account up to an additional $4,000,000 of the Bogen Sale
                  Proceeds for the working capital needs and general corporate
                  purposes of the Company and its Subsidiaries.

                           (d) On or after the expiration of 45 days from the
                  date of the FCC's order approving the License Reallocation and
                  the delivery to the Trustee of the Officers' Certificate and
                  opinion of counsel referred to in Section 4.1.11 of the U.S.
                  Pledge Agreement, the Company may withdraw the balance of the
                  Bogen Sale Proceeds from the Custody Account for the working
                  capital needs and general corporate purposes of the Company
                  and its Subsidiaries.

                           (e) No Bogen Sale Proceeds shall be withdrawn from
                  the Custody Account for the working capital needs and general
                  corporate purposes of the Company and its Subsidiaries if a
                  Default or Event of Default has occurred and is continuing,
                  and the Company shall deliver to the Trustee an Officers'
                  Certificate to such effect at the time of any such withdrawal.
                  Any Bogen Sale Proceeds which are applied to the working
                  capital needs and general corporate purposes of the Company
                  and its Subsidiaries shall constitute Working Capital Proceeds
                  from a Permitted Asset Sale occurring after November 1, 1997.

                           (f) The Company may at any time apply all or any part
                  of the Bogen Sale Proceeds remaining in the Custody Account to

                  purchase Replacement Collateral or to pay outstanding invoices
                  for previously purchased Replacement Collateral, provided that
                  not less than 33 % of the Bogen Sale Proceeds so applied shall
                  be used to purchase Northeast Replacement Collateral or to pay
                  outstanding invoices for previously purchased Northeast
                  Replacement Collateral. The Company may withdraw the Bogen
                  Sale Proceeds from the Custody Account for the purchase of (or
                  payment of outstanding invoices for) Replacement Collateral

                                      11

<PAGE>

                  upon delivery to the Trustee of (i) an Officers' Certificate
                  certifying (A) the type of Replacement Collateral to be
                  purchased (or paid for), the locations where such Collateral
                  will be (or has been) installed or used, and the fact that
                  such Replacement Collateral will meet the requirements of the
                  Indenture relating to Replacement Collateral, and (B) that no
                  Default or Event of Default has occurred and is continuing,
                  and (ii) an opinion of independent counsel that such
                  Replacement Collateral will be subject to a first priority
                  perfected Lien in favor of the Trustee under the GEONET System
                  Security Agreement or will be Licenses held by the License
                  Holding Company, all of the capital stock of which is subject
                  to a first priority perfected Lien in favor of the Trustee
                  under the U.S. Pledge Agreement; provided, however, that no
                  such opinion shall be required with respect to (A) Northeast
                  Replacement Collateral which will be installed in
                  jurisdictions (both state and local) containing Collateral
                  with respect to which an opinion of independent counsel was
                  previously furnished to the Trustee (provided that in such
                  case the next annual Opinion of Counsel furnished to the
                  Trustee under Section 10.02(c) shall expressly cover such
                  newly installed Northeast Replacement Collateral), or (B)
                  Other Replacement Collateral if the cost thereof, when added
                  to the cost of all other Other Replacement Collateral being
                  installed in the same state, does not exceed $1,000,000,
                  except that if Other Replacement Collateral will be installed
                  in a state with respect to which no opinion of independent
                  counsel has been previously furnished to the Trustee, such
                  opinion of independent counsel shall nevertheless be required
                  if the cost of such Other Replacement Collateral, when added
                  to the cost of all other Other Replacement Collateral being
                  installed or previously installed in such state, will exceed
                  $1,000,000; and further provided, that upon the First
                  Amendment to this Indenture becoming effective, the Company
                  may make an initial withdrawal of Bogen Sale Proceeds of up to
                  $2,750,000 for the purchase of (or payment of outstanding
                  invoices for) Other Replacement Collateral without delivering
                  such opinion of independent counsel provided that such opinion
                  is delivered to the Trustee within thirty (30) days
                  thereafter. Nothing contained in this Section 4.20 shall amend
                  or modify the obligation of the Company to furnish to the

                  Trustee the annual Opinion of Counsel required under Section
                  10.02(c).

                           (g) Any Bogen Sale Proceeds that are not withdrawn
                  for working capital needs and general corporate purposes or
                  invested in Replacement Collateral as required by this Section
                  4.20 within 18 months of the Bogen Sale shall constitute
                  "Excess Proceeds" subject to disposition as provided in
                  Section 4.12(b) (but without regard to the $10,000,000
                  threshold set forth therein).

                  4.21  Restrictions Pending License Reallocation.

                           Unless and until the Company has completed the
                  License Reallocation and the Trustee has received the
                  Officers' Certificate and opinion of counsel referred to in
                  Section 4.1.11 of the U.S. Pledge Agreement, the Company will
                  not, and will not permit any of its Subsidiaries to, (i) use
                  any Net Cash Proceeds from a Permitted Asset Sale or a
                  Permitted Foreign Asset Sale for the working capital needs and
                  general corporate purposes of the Company or any of its
                  Subsidiaries, except as permitted by Section 4.20, (ii) incur
                  or permit to exist any Indebtedness under Section 4.08(n) or
                  4.08(o) of the Indenture, or (iii) grant or permit to exist
                  any Lien under clause (k) of the definition of Permitted Liens
                  which, together with all other Liens granted or permitted to
                  exist under such clause, in the aggregate secure more than
                  $10,000,000 of Indebtedness.

                  4.22  Quarterly Compliance Certificate Regarding Custody 
                        Account

                           The Company will deliver to the Trustee, within 15
                  days after the end of each fiscal quarter, a statement setting
                  forth the following information as of the end of such fiscal
                  quarter, in each case for the Custody Account as a whole and
                  for the amounts in the Custody Account derived from the Bogen
                  Sale, Permitted Foreign Asset Sales and Collateral Sales: (i)
                  the amount in the Custody Account, (ii) any additional Net
                  Cash Proceeds deposited in the Custody Account since the end
                  of the prior fiscal quarter, indicating the source of such Net
                  Cash Proceeds, (iii) any funds withdrawn from the Custody
                  Account and the use to which such funds were applied, (iv) the
                  total amounts withdrawn from the Custody Account to date for
                  working capital needs and general corporate purposes, (v) the
                  total amounts withdrawn from the Custody Account to date for
                  investment in Northeast Replacement Collateral and Other
                  Reinvestment Collateral, (vi) the total amounts withdrawn from
                  the Custody Account to date for use as Excess Proceeds, (vii)
                  the total amount 


                                      13

<PAGE>

                  of Working Capital Proceeds generated to date by all other
                  Permitted Asset Sales (the Net Cash Proceeds of which were not
                  deposited in the Custody Account), and (viii) the total amount
                  of Working Capital Proceeds generated to date by Indebtedness
                  incurred under Section 4.08(n).

                  8. Events of Default. Section 6.01 of the Indenture is hereby
amended to amend and restate clause (c) in its entirety to read as follows:

                           (c) a failure to perform or observe any other term,
                  covenant or agreement contained in the Securities, this
                  Indenture, the Custody Account Pledge Agreement or any of the
                  Pledge Agreements or Security Agreements (other than a default
                  specified in clause (a) or (b) above), which failure continues
                  for a period of 30 days after written notice thereof requiring
                  the Company to remedy the same shall have been given (i) to
                  the Company by the Trustee or (ii) to the Company and the
                  Trustee by Holders of at least 25% aggregate principal amount
                  of the Securities then outstanding; or

                  9. Release of Collateral. Section 10.03(a) of the Indenture is
hereby amended to amend and restate the proviso in the second sentence of such
Section as follows:

                  provided, that if such sale, conveyance or disposition
                  constitutes an Asset Sale, the Company shall apply the Net
                  Cash Proceeds in accordance with Sections 4.12 (Asset Sales
                  generally), 4.20 (the Bogen Sale) and 10.08 (Permitted Foreign
                  Asset Sales and Collateral Sales) and any such agreements, to
                  the extent applicable.

                  10. Permitted Foreign Asset Sales; Collateral Sales. Section
10.08 of the Indenture is hereby amended and restated in its entirety to read as
follows:

                           (a) The Company will not, and will not permit any of
                  its Subsidiaries to, make any Permitted Foreign Asset Sale or
                  any Collateral Sale unless the requirements of Section
                  4.12(a)(i) and (iii) and this Section 10.08 are satisfied.

                           (b) The Company or its Subsidiary, as the case may
                  be, shall apply the Net Cash Proceeds from a Permitted Foreign
                  Asset Sale as follows: (i) not less than 20% of such Net Cash
                  Proceeds shall constitute "Excess Proceeds" (the "Excess
                  Proceeds Share"), which the Company shall use within 30 days
                  after such Sale to make an Asset Sale Offer in accordance with
                  Section 4.12(b) (but 

                                      14


<PAGE>

                  without regard to the $10,000,000 threshold set forth
                  therein); (ii) within 18 months after such Sale, the Company
                  or such Subsidiary shall apply not less than 40% of such Net
                  Cash Proceeds (less the amount of any Bogen Sale Reinvestment
                  Credit) (the "Reinvestment Share") to purchase Northeast
                  Replacement Collateral, provided that the Company may use up
                  to $10,000,000 of the Reinvestment Share (less the amount of
                  any Bogen Sale Other Reinvestment Credit) for investment in
                  Other Replacement Collateral; and (iii) so long as no Default
                  or Event of Default has occurred and is continuing, the
                  Company or such Subsidiary may apply up to 40% of such Net
                  Cash Proceeds (plus the amount of any Bogen Sale Reinvestment
                  Credit) (the "Working Capital Share") to the working capital
                  needs and general corporate purposes of the Company and its
                  Subsidiaries; provided, however, that if the consideration for
                  a Permitted Foreign Asset Sale does not consist entirely of
                  cash and Cash Equivalents or the assumption of Assumed
                  Obligations, then (x) the Working Capital Share shall be
                  reduced (on a dollar-for-dollar basis, but not less than zero)
                  by the amount of the consideration which is not cash or Cash
                  Equivalents or Assumed Obligations, (y) the Excess Proceeds
                  Share shall be increased by one-third of the amount of such
                  reduction and the Reinvestment Share shall be increased by
                  two-thirds of the amount of such reduction, and (z) the amount
                  of the Reinvestment Share that would otherwise be available
                  for investment in Other Replacement Collateral under the
                  foregoing allocation shall be reduced by the percentage that
                  the noncash consideration bears to the total consideration for
                  such Sale. If within 18 months after a Permitted Foreign Asset
                  Sale, the Company has not invested the Reinvestment Share in
                  Replacement Collateral, the uninvested amount of the
                  Reinvestment Share shall constitute Excess Proceeds and shall
                  be used to make an Asset Sale Offer in accordance with Section
                  4.12(b) (but without regard to the $10,000,000 threshold set
                  forth therein). The Company shall cause any noncash proceeds
                  (including securities) from a Permitted Foreign Asset Sale to
                  immediately become subject to a first priority perfected Lien
                  in favor of the Trustee. If such noncash proceeds are
                  subsequently sold for cash, the Company may, so long as no
                  Default or Event of Default has occurred and is continuing,
                  apply the Net Cash Proceeds from such sale to the working
                  capital needs and general corporate purposes of the Company
                  and its Subsidiaries; provided, however, that the amount of
                  such Net Cash Proceeds that are 

                                               15

<PAGE>

                  applied to working capital needs and general corporate
                  purposes, when taken together with all other Net Cash Proceeds

                  from the Permitted Foreign Asset Sale that are so applied,
                  shall not exceed the Working Capital Share that would have
                  resulted if all of the consideration from such Asset Sale had
                  been cash.

                           (c) The Company or its Subsidiary, as the case may
                  be, shall apply the Net Cash Proceeds from a Collateral Sale
                  (other than the Bogen Sale) to the purchase of Replacement
                  Collateral; provided, however, that if the Collateral Sale
                  involves any Collateral which is part of or used in connection
                  with any GEONET system located in the Northeast Licensed Area,
                  the Net Cash Proceeds therefrom shall be applied solely to the
                  purchase of Northeast Replacement Collateral; and provided
                  further, that if the Collateral Sale involves the sale of a
                  Northeast License as permitted by Section 10.08(e)(ii)(B), the
                  cash proceeds therefrom shall be applied solely to the
                  purchase of Licenses that will constitute Northeast
                  Replacement Collateral. Any Net Cash Proceeds from a
                  Collateral Sale that are not invested in Replacement
                  Collateral as required by this Section 10.08(c) within 18
                  months of such Sale shall constitute "Excess Proceeds" subject
                  to disposition as provided in Section 4.12(b) (but without
                  regard to the $10,000,000 threshold set forth therein). Except
                  for the use of the Bogen Sale Proceeds as permitted by Section
                  4.20, the Net Cash Proceeds from a Collateral Sale shall not
                  be used for the working capital needs and general corporate
                  purposes of the Company and its Subsidiaries. The Company
                  shall cause any noncash proceeds (including securities) from a
                  Collateral Sale to immediately become subject to a first
                  priority perfected Lien in favor of the Trustee.
                  Notwithstanding the foregoing, in the event of a sale of
                  Collateral which is subject to a Release Condition Senior Lien
                  (as defined in the U.S. Pledge Agreement), the application of
                  the proceeds of such sale pursuant to this Section 10.08(c)
                  shall be subject to the prior application of such proceeds to
                  any Indebtedness secured by such Release Condition Senior
                  Lien.

                           (d) Subject to the provisions of Section 10.08(e),
                  any Liens in favor of the Trustee on the assets (including
                  stock) sold in a Permitted Foreign Asset Sale or a Collateral
                  Sale will be released upon (i) the deposit of the Net Cash
                  Proceeds from such Sale in the Custody Account subject to a
                  first priority perfected Lien in 

                                      16

<PAGE>


                  favor of the Trustee, and (ii) the delivery to the Trustee of
                  an Officers' Certificate and opinion of independent counsel
                  that any noncash proceeds from such Sale are subject to a
                  first priority perfected Lien in favor of the Trustee. The Net

                  Cash Proceeds shall continue to be held in the Custody Account
                  until such Proceeds have been applied in the manner set forth
                  in Section 10.08(b) (in the case of a Permitted Foreign Asset
                  Sale) or Section 10.08(c) (in the case of a Collateral Sale).
                  So long as no Default or Event of Default has occurred and is
                  continuing, the Company may withdraw such Net Cash Proceeds
                  from the Custody Account upon its delivery to the Trustee and
                  the custodian of (A) an Officers' Certificate certifying (1)
                  the purpose for which the withdrawn funds will be used, (2)
                  the amount of the requested withdrawal, (3) in the case of
                  withdrawals for working capital needs and general corporate
                  purposes, the total amount of Working Capital Proceeds
                  previously withdrawn from the Custody Account and the amount
                  of available Working Capital Proceeds remaining in the Custody
                  Account (prior to the requested withdrawal), (4) in the case
                  of withdrawals for investment in Replacement Collateral, the
                  type of Collateral to be purchased, the locations where such
                  Collateral will be installed or used, and the fact that such
                  Replacement Collateral will meet the requirements of the
                  Indenture relating to Replacement Collateral, and (5) that no
                  Default or Event of Default has occurred and is continuing,
                  and (B) in the case of withdrawals for investment in
                  Replacement Collateral, an opinion of independent counsel that
                  such Replacement Collateral will be subject to a first
                  priority perfected Lien in favor of the Trustee under the
                  GEONET System Security Agreement or will be Licenses held by
                  the License Holding Company, all of the capital stock of which
                  is subject to a first priority perfected Lien in favor of the
                  Trustee under the U.S. Pledge Agreement; provided, however,
                  that no such opinion shall be required with respect to (A)
                  Northeast Replacement Collateral which will be installed in
                  jurisdictions (both state and local) containing Collateral
                  with respect to which an opinion of independent counsel was
                  previously furnished to the Trustee (provided that in such
                  case the next annual Opinion of Counsel furnished to the
                  Trustee under Section 10.02(c) shall expressly cover such
                  newly installed Northeast Replacement Collateral), or (B)
                  Other Replacement Collateral if the cost thereof, when added
                  to the cost of all other Other Replacement Collateral being
                  installed in the same state, does not exceed $1,000,000,
                  except that if 

                                      17

<PAGE>

                  Other Replacement Collateral will be installed in a state with
                  respect to which no opinion of independent counsel has been
                  previously furnished to the Trustee, such opinion of
                  independent counsel shall nevertheless be required if the cost
                  of such Other Replacement Collateral, when added to the cost
                  of all other Other Replacement Collateral being installed or
                  previously installed in such state, will exceed $1,000,000.

                  transfer, lease or otherwise dispose of, or grant any rights

                  best efforts to cause the removal of such License Restriction

                  Geotek shall take all actions necessary to provide the

entirety to read as follows, and the last paragraph of Section 7.14 of the

                           In addition, in the event that any Pledged Collateral
                  is sold or transferred in a transaction permitted by this
                  Agreement and the Indenture, the Collateral Agent shall

                  Pledged Collateral so sold or transferred on the terms and
                  conditions set forth in Section 10.08 of the Indenture.

                  11. Conditions Precedent. The amendment of the Pledge

thereof have been satisfied.

                  12. Counterparts. This First Amendment may be signed in any
number of counterpart copies, each of which shall constitute an original, with
the same effect as if the signatures thereon and hereon were upon the same
instrument.

         13. Governing Law. This First Amendment shall be construed, interpreted
and governed by the laws of the State of New York, without giving effect to the
principles of conflicts of law.

                  14. No Other Amendments. Except as to the matters referred to
in this First Amendment, the Pledge Agreement shall remain in full force and
effect in accordance with its terms.

ARTICLE 2.            SECURITY INTERESTS

         2.1          Grant of Security Interests.

         To secure the full and punctual payment of all Obligations, and in
order to induce the Collateral Agent to enter into the First Amendment and any
other related amendments and agreements, the Company hereby collaterally assigns
to the Collateral Agent for the benefit of the Securityholders, and grants to
the Collateral Agent a security interest in, all right, title and interest of
the Company, or any of them, or any Subsidiary, in, to and under the following
assets, whether now existing or hereafter acquired, to the extent and only to
the extent any such asset is a Qualifying Asset (all of which are herein
collectively referred to as the "Collateral"):

                      (a)     all Intangibles;

                      (b)     all Equipment;

                      (c)     all Leases;


                      (d) to the extent not included in the foregoing, all
         books, ledgers and records and all computer programs, tapes, discs,
         punch cards, data processing software, transaction files, master files
         and related property and rights (including computer and peripheral

         establishing any item of Collateral (subject to Section 5.3 hereof);
         and

                      (e) to the extent not otherwise included, all Proceeds and
         products of any or all of the foregoing, whether existing on the date
         hereof or arising hereafter.

         2.2          Continuing Liability of the Company.

         Anything herein to the contrary notwithstanding, the Company shall
remain liable to observe and perform all the terms and conditions to be observed
and performed by it under any contract, 

                                      6

<PAGE>

lease, agreement, warranty or other obligation with respect to the Collateral,
and shall do nothing to impair the security interests herein granted. The
Collateral Agent shall not have any obligation or liability under any such
contract, agreement, warranty or obligation by reason of or arising out of this
Security Agreement or the receipt by the Collateral Agent of any payment
relating to any Collateral, nor shall the Collateral Agent be required to
perform or fulfill any of the obligations of the Company with respect to the
Collateral, to make any inquiry as to the nature or sufficiency of any payment
received by it or the sufficiency of the performance of any party's obligations
with respect to any Collateral. Furthermore, the Collateral Agent shall not be
required to file any claim or demand to collect any amount due or to enforce the
performance of any party's obligations with respect to, the Collateral.

         2.3          Sales and Collections.

                      Except as expressly provided in the Indenture, the 
Company will not, and will not permit any of its or their Subsidiaries to,
directly or indirectly sell, convey, transfer, lease or otherwise dispose of any
Collateral.

         2.4          Release of Collateral.

         Upon the final indefeasible payment in full in cash and performance of
the Obligations, this Agreement and the covenants contained herein shall
terminate (except for Sections 4.19, 6.3 and 6.4 hereof) and the Collateral
shall be released by the Collateral Agent to the Company and the Collateral
Agent shall have no further security interest in the Collateral. In addition,
this Agreement shall terminate (except for the Sections 4.19, 6.3 and 6.4
hereof) and the Collateral shall be released upon the prior written consent of
the holders of at least 66 2/3% of the aggregate principal amount of the
Securities then outstanding (the "Requisite Vote") pursuant to a request (a
"Collateral Release Request") made by the Company to the holders. In the event

that the Company does not receive the Requisite Vote pursuant to any such
Collateral Release Request, the Company may, at its option, within five business
days after the latest date on which such consents are required to be delivered
to the Company pursuant to the terms of the Collateral Release Request, make an
offer to purchase (a "Collateral Release Repurchase Offer") all of the
outstanding Securities at a purchase price of 101.5% of the Accreted Value
thereof, plus accrued and unpaid interest, if any, to the date of repurchase.
Upon the consummation of such Collateral Release Repurchase Offer, this
Agreement automatically shall terminate and the Collateral shall be released. If
the Company shall at any time make a Collateral Release Request, the Company
shall pay to the voting holders an amount in cash equal to .50% of the Accreted
Value on such date as provided in the Indenture. Any Collateral Release Request
shall be made as 

                                      7

<PAGE>

provided in the Indenture. Upon such termination, the Collateral Agent shall
promptly reassign and redeliver (or cause to be reassigned and redelivered) to
the Company, or to such person or persons as the Company shall designate or to
whomever may be lawfully entitled to receive such surplus, against receipt, such
of the Collateral (if any) as shall not have been sold or otherwise applied by
the Collateral Agent pursuant to the terms hereof and shall still be held by it
hereunder, together with appropriate instruments of reassignment and release.
Any such reassignment shall be without recourse upon or warranty by the
Collateral Agent (other than a warranty that the Collateral Agent has not
assigned or delivered the Collateral so reassigned and redelivered its rights
and interests hereunder to any other person) and at the expense of the Company.
Upon final indefeasible payment in full in cash and performance of the
Obligations, the Collateral Agent will (as soon as reasonably practicable after
receipt of notice from the Company requesting the same but at the expense of the
Company) send the Company, for each jurisdiction in which a UCC financing
statement is on file to perfect the security interests granted to the Collateral
Agent hereunder, a termination statement.

         2.5          Certain Assurances Regarding Subsidiaries and Collateral.

         In the event that it is at any time or from time to time determined
that any Subsidiary has any right, title or interest in any asset which, if
owned by Company, or any of them, would be Collateral hereunder, or if the
Company, or any of them, acquires any right, title or interest in any asset
which constitutes Collateral but which is not adequately described or included
in this Security Agreement or any applicable financing statement in the
necessary manner to grant to the Collateral Agent a valid first priority
perfected security interest in such asset, then, without notice or demand from
the Collateral Agent, the Company shall immediately furnish written notice of
such fact to the Collateral Agent and the Company shall immediately take all
necessary and appropriate action, and Company shall cause any and all such
Subsidiaries to immediately take all necessary and appropriate actions
(including without limitation, execution of or joinder to this Security
Agreement), (i) to grant to the Collateral Agent for the benefit of the
Securityholders a first priority perfected lien in such assets in accordance
with the provisions of this Security Agreement, and (ii) to bind any and all

such Subsidiaries to all of the provisions of this Security Agreement without
exception.

         2.6          Consents Regarding Licenses and Leases. 

                      To the extent that Company's right to assign to the  
Collateral Agent, and to grant it a security interest in, any Licenses or Leases
is conditioned upon any third party's consent, Company shall use its
commercially reasonable efforts to expeditiously procure such 

                                      8

<PAGE>

consent; provided, however, that, unless an Event of Default shall have occurred
and be continuing, the Company shall have no obligation to comply with this
Section 2.6 with respect to (i) any Leases existing as of December 15, 1997, and
(ii) any agreements between the Company and its Subsidiaries and Raphael
Armaments Development Agency.

         The Company represents and warrants that:

         3.1          Validity of Security Agreement; Consents.

                      (a)     The execution, delivery and performance of this 
Security Agreement by the Company and the creation of the security interests

Security Agreement by the Company, the creation of the security interests
provided for herein, and the exercise and enforcement by the Collateral Agent
(including its successors and assigns) of its rights and remedies hereunder upon
the occurrence of an Event of Default, including without limitation the
possession, use and operation of the Collateral by the Collateral Agent and the
sale of the Collateral in whole or in part by the Collateral Agent to a third

Company, or any of them, except to the extent that FCC Licenses may be needed to

result in a breach of, or constitute a default under, any indenture, mortgage,
deed of trust, license agreement, lease, or other agreement or instrument to

<PAGE>

that (A) the transfer of the FCC Licenses needed to operate such GEONET systems
would require the approval of the FCC and (B) the assignment of Leases of Real
Estate may require the consent of the lessors, and except for any such consents
or approvals which, if not procured, would not in the aggregate have a material
adverse effect on the business, assets, operations or financial condition of the
Company or the value of the Collateral or the ability of the Collateral Agent or
any purchaser of the Collateral to own, operate, use, sell or otherwise transfer
the Collateral.

                      (c)     This Security Agreement has been duly executed 
and delivered by the Company and constitutes the legal, valid and binding
obligation of the Company, enforceable against it, and each of them, in
accordance with its terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
relating to or affecting the enforceability of creditors' rights generally and
by general provisions of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

        3.2          Title to Collateral; All Necessary Northeast Licensed 
                     Area Assets.

                      (a)     Except for the security interests granted to the 
Collateral Agent pursuant to this Security Agreement, the Company is the sole
owner of each item of the Collateral, having good title thereto, free and clear
of any and all Liens exclusive of Permitted Liens (as such term is modified in
Section 3.3(b) hereof).

                      (b)     The Collateral includes all material assets, 
property interests and rights (including all intellectual property) necessary
for the operation of the Company's GEONET systems in the Northeast Licensed
Area, such that upon the occurrence of an Event of Default the Collateral Agent
or any purchaser of the Collateral could use and operate such GEONET systems in
substantially the same manner that such GEONET systems are presently operated by
the Company, without (i) violating any law or regulation or any order or decree
of any court or governmental instrumentality, except to the extent that FCC
Licenses may be needed to use and operate such GEONET systems, (ii) causing or
creating a conflict with or a breach of, or a default under, any indenture,
mortgage, deed of trust, license agreement, lease, or other agreement or
instrument to which any of the Collateral is subject, except for conflicts,
breaches or defaults which would not in the aggregate have a material adverse
effect on the ability of the Collateral Agent or such purchaser to own, operate,
use, sell or otherwise transfer the Collateral, or (iii) obtaining the consent
or approval of any governmental authority or other person, except that (A) the
transfer of the 


                                      10

<PAGE>

FCC Licenses needed to operate such GEONET systems would require the approval of
the FCC and (B) the assignment of Leases of Real Estate may require the consent
of the lessors, and except for any such consents or approvals which, if not
procured, would not in the aggregate have a material adverse effect on the
ability of the Collateral Agent or such purchaser to own, operate, use, sell or
otherwise transfer the Collateral.

                      (c)     All of the leasehold interests and any other 
rights or assets previously held by the Subsidiaries of Geotek USA (including
without limitation the PowerSpectrum Subsidiaries) which are part of, used in
connection with or otherwise relate to the Northeast Licensed Area, have been
assigned or otherwise transferred to Geotek USA, except for the leases listed on
the attached Schedule 10(a).

                      (d)     Geotek America owns no leasehold interests or 
other rights or assets which are part of, used in connection with or otherwise
relate to the Northeast Licensed Area except for the leases listed on the
attached Schedule 10(b).

         3.3          Validity, Perfection and Priority of Security Interests.

                      (a)     By complying with Section 4.1 hereof, Company 
will have created a valid perfected first priority security interest in favor of
the Collateral Agent in all existing Collateral and in all identifiable Proceeds
of such Collateral subject only to Permitted Liens (as such term is modified in
Section 3.3(b) hereof). Continuing compliance by Company with the provisions of
Section 4.2 hereof will also (i) create valid security interests in all
Collateral acquired after the date hereof and in all identifiable Proceeds of
such Collateral and (ii) cause such security interests in all Collateral and in
all Proceeds which are (A) identifiable cash Proceeds of Collateral covered by
financing statements required to be filed hereunder and (B) identifiable
Proceeds in which a security interest may be perfected by such filing under the
UCC to be, in each case, prior to the claims of a trustee in bankruptcy under
the United States Federal Bankruptcy Code.

                      (b)     The security interests of the Collateral Agent 
in the Collateral, as set forth in Section 3.3(a) hereof, rank first in
priority, except that the priority of the security interests may be subject to
Permitted Liens (exclusive of those Permitted Liens described in paragraphs (g),
(h), (j), (k) and (l) of the definition of Permitted Liens contained in Section
1.01 of the Indenture and exclusive of Liens described in clauses (iii), (iv)
and (v) of the proviso set forth in Section 4.10 of the Indenture). Except as
described in the immediately preceding sentence, other than financing statements
or other similar documents perfecting the security interests or deed of trust

                                      11

<PAGE>

liens of the Collateral Agent, no financing statements, deeds of trust,

mortgages or similar documents covering all or any part of the Collateral are on
file or of record in any government office in any jurisdiction in which such
filing or recording would be effective to perfect a security interest in such
Collateral, nor is any of the Collateral in the possession of any Person (other
than the Company) asserting any claim thereto or security interest therein.

         3.4          Enforceability of Intangibles.

         To the best knowledge of the Company, each Intangible is a valid and
binding obligation of the related third party in respect thereof, enforceable in
accordance with its terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditors' rights generally and by general
provisions of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law), and complies with any applicable legal
requirements.

         3.5          Place of Business; Location of Collateral.

         The attached Schedule 3 correctly sets forth the Company's (and each of
their) chief executive office and principal place of business of the Company,
and each of them, and the offices of the Company where records concerning
Intangibles are kept. The attached Schedule 4 correctly sets forth the location
of all Equipment. Except as otherwise specified in the attached Schedule 4, all
Equipment has been located at the address(es) specified on such Schedule 4 at
all times during or acquired by the Company within the four-month period prior
to the date hereof while owned by the Company, or any of them. No amount payable
under or in connection with any of the Collateral is evidenced by promissory
notes or other instruments. The leased real estate listed in the attached
Schedule 5 includes all existing Real Estate which constitutes Qualifying
Assets. The attached Schedule 6 lists all material Leases constituting
Qualifying Assets, provided that for purposes of this Security Agreement, all
leased Real Estate shall be considered material.

         3.6          Trade Names.

         Any and all trade names, division names, assumed names or other names
under which the Company, or any of them, transacts, or within the four-month

rules, regulations, orders, decrees and directions of any governmental authority
applicable to the Collateral or any part thereof or to the operation of the
Company's business except to the extent that the failure to comply would not
have a material adverse effect on the financial or other condition of the
Company, or any of them; provided, however, that the Company may contest any
act, regulation, order, decree or direction in any reasonable manner which shall

written consent, grant any extension of the amounts due under any material
Intangible, compromise, compound or settle the same for less than the full
amount thereof, release, wholly or partly, any person liable for the payment
thereof or allow any credit or discount whatsoever thereon other than trade

Collateral Agent against liability for personal injury arising from, and
property damage relating to, such Equipment, such policies to be in amounts
customary and appropriate for companies engaged in the same or similar business,

composition of the Collateral, and (c) of the occurrence of any other event

ARTICLE 5.            REMEDIES; RIGHTS UPON DEFAULT

         5.1          UCC Rights.

in this Security Agreement and in any other instrument or agreement securing,

secured party under the UCC and all other rights available to the Collateral
Agent at law or in equity.

         5.2          Payments on Collateral.

         Without limiting the rights of the Collateral Agent under any other
provision of this Security Agreement, if an Event of Default shall occur and be
continuing:

                      (a)     all payments received by the Company under or in 
connection with any of the Collateral shall be held by the Company in trust for
the Collateral Agent, shall be segregated from other funds of the Company and
shall forthwith upon receipt by the Company be turned over to the Collateral
Agent, in the same form as received by the Company (duly endorsed by the Company
to the Collateral Agent, if required to permit collection thereof by the
Collateral Agent); and

                      (b)     all such payments received by the Collateral 
Agent (whether from the Company or otherwise) may, in the sole discretion of the
Collateral Agent, be held by the Collateral Agent as collateral security for,

Collateral Agent to the payment of the expenses and Obligations as set forth in
Section 5.10 hereof.

be located, and without charge or liability to the Collateral Agent seize and
remove such Collateral from such premises and (b) have access to and use of the
Company's books, records, files and other documents relating to such Collateral.
The Company may retain possession of any books, records, files and other
documents that do not relate primarily to the Northeast Licensed Area, provided

books, records, files and other documents and furnishes to the Collateral Agent
such copies thereof as it may from time to time request.

         5.4          Sale of Collateral.

                      (a)     The Company expressly agrees that if an Event of 
Default shall occur and be continuing, the Collateral Agent, without demand of
performance or other demand or notice of any kind (except the notice specified
below of the time and place of any public or private sale) to the Company or any
other Person (all of which demands and/or notices are hereby waived by the
Company), may forthwith collect, receive, appropriate and realize upon the
Collateral and/or forthwith sell, lease, assign, give an option or options to
purchase or otherwise dispose of and deliver the Collateral (or contract to do
so) or any part thereof in one or more parcels at public or private sale, at any
exchange, broker's board or at any office of the Collateral Agent or elsewhere
in such manner as is commercially reasonable and as the Collateral Agent may
deem best, for cash or on credit or for future delivery without assumption of
any credit risk. The Collateral Agent shall have the right upon any such public
sale, and, to the extent permitted by law, upon any such private sale, to
purchase the whole or any part of the Collateral so sold. The Company further
agrees, at the Collateral Agent's request, to assemble the Collateral, and to
make it available to the Collateral Agent at places which the Collateral Agent
may reasonably select. To the extent permitted by applicable law, the Company
waives all claims, damages and demands against the Collateral Agent arising out
of the foreclosure, repossession, retention or sale of the Collateral.

                      (b)     Unless the Collateral threatens to decline 
speedily in value or is of a type customarily sold in a recognized market, the
Collateral Agent shall give the Company twenty days' written notice of its
intention to make any such public or private sale or sale at a broker's board or
on a securities exchange. Such notice shall (i) in the case of a public sale,
state the time and place fixed for such sale, (ii) in the case of a sale at a
broker's board or on a securities exchange, state the board or exchange at which
such sale is to be made and the day on which the Collateral, or any portion
thereof being sold, will first be offered for sale and (iii) in the case of a
private sale, state the day after which such sale may be consummated. The
Collateral Agent shall not be required or obligated to make any such sale
pursuant to any such notice. The Collateral Agent may adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for the sale, and such sale may be made at any time
or place to which the same may be so adjourned. In the case of any sale of all
or any part of the Collateral for credit or for future delivery, the Collateral
so sold may be retained by the Collateral Agent until the selling price is paid

by the purchaser thereof, but the Collateral Agent shall not incur any liability
in case of failure of such purchaser to pay for the 

                                      22

<PAGE>

Collateral so sold and, in the case of such failure, such Collateral may again
be sold upon like notice.

         5.5          Rights of Purchasers.

         Upon any sale of the Collateral (whether public or private) by the
Collateral Agent as described in this Security Agreement, the Collateral Agent
shall have the right to deliver, assign and transfer to the purchaser thereof
the Collateral so sold. Each purchaser (including the Collateral Agent) at any
such sale shall hold the Collateral so sold free from any claim or right of
whatever kind, except Permitted Liens (as such term is modified in Section
3.3(b) hereof), including any equity or right of redemption of the Company, and
the Company, to the extent permitted by law, hereby specifically waives all
rights of redemption, including, without limitation, the right to redeem the
Collateral under Section 9-506 of the UCC, and any right to a judicial or other
stay or approval which it has or may have under any law now existing or
hereafter adopted.

         5.6          Intellectual Property.

                      (a)     The Company, and each of them, hereby grants to 
the Collateral Agent, for the benefit of the Securityholders, upon the
occurrence and during the continuation of an Event of Default, an irrevocable
nonexclusive, royalty-free license or sublicense under all Patents, Licenses and
other Intangibles (other than Trademarks) that do not constitute Collateral to
provide wireless telecommunications services and related equipment and products
in the Northeast Licensed Area, except (in the case of Licenses and other
Intangibles) to the extent that the license agreement or other agreement
pursuant to which the Company holds such Licenses or other Intangibles requires
the consent of the licensor or other third party and the Company is not able
(after making commercially reasonable efforts to do so) to obtain such consent;
provided, however, that the Company shall not be required to use its efforts to

                      (b)     The Company, and each of them, hereby authorizes,
on behalf of itself and its Subsidiaries, Rafael to grant to the Collateral

provisions and other provisions of their respective agreements with Rafael, a

                      (c)     The Company, and each of them, hereby grants to 
the Collateral Agent, for the benefit of the Securityholders, upon the
occurrence and during the continuation of an Event of Default, an irrevocable
nonexclusive royalty-free license under their intellectual property rights to
use the Trademarks that do not constitute Collateral in connection with the
provision of wireless telecommunications services and related equipment and
products in the Northeast Licensed Area, provided that all goods and services
offered, sold or provided in conjunction with the Trademarks shall meet or
exceed the quality standards reasonably imposed by Company.

                      (e)     The Collateral Agent shall be entitled to assign 
or sublicense its rights under the licenses in this Section 5.6 in whole or
relevant part in connection with any sale or other disposition of Collateral in
accordance with this Article 5.

                      (f)     The Company, and each of them, hereby grants to 
any successor of the Company, or any of them (including without limitation any
reorganized debtor under a Chapter 11 Plan of Reorganization approved by the
Securityholders) the right to use the Patents, Trademarks, copyrights, Licenses
and other Intangibles of the Company, and each of them, and its Subsidiaries,
subject to the rights of the Collateral Agent under this Agreement.

         5.7          Additional Rights of the Collateral Agent.

                      (a)     The Company expressly agrees that if an Event of 
Default shall occur and be continuing, the Collateral Agent shall have the right
and power to institute and maintain such suits and proceedings as it may deem
appropriate to protect and enforce the rights vested in it by this Security
Agreement and may proceed by suit or suits at law or in equity to enforce such
rights and to foreclose upon and sell the Collateral or any part thereof
pursuant to the judgment or decree of a court of competent jurisdiction.

                      (b)     The Collateral Agent shall, to the extent 
permitted by law and without regard to the solvency or insolvency at the time of
any Person then liable for the payment of any of the Obligations or the then
value of the Collateral, and without requiring any bond from any party to such
proceedings, be entitled to the appointment of a special receiver or receivers
(who may be the Collateral Agent) for the Collateral or any part thereof and for
the rents, issues, tolls, profits, royalties, revenues and other income
therefrom, which receiver shall have such powers as the court making such
appointment shall confer, and to the entry of an order directing that the rents,
issues, tolls, profits, royalties, revenues and other income of the property
constituting the whole or any part of the Collateral be segregated, sequestered
and impounded for the benefit of the 

                                      24

<PAGE>

Collateral Agent, and the Company irrevocably consents to the appointment of
such receiver or receivers and to the entry of such order.


         5.8          Remedies Not Exclusive.

                      (a)     No remedy conferred upon or reserved to the 
Collateral Agent in this Security Agreement is intended to be exclusive of any
other remedy or remedies, but every such remedy shall be cumulative and shall be
in addition to every other remedy conferred herein or now or hereafter existing
at law, in equity or by statute.

                      (b)     If the Collateral Agent shall have proceeded to
enforce any rights, remedy or power under this Security Agreement and the
proceeding for the enforcement thereof shall have been discontinued or abandoned
for any reason or shall have been determined adversely to the Collateral Agent,
the Company and the Collateral Agent shall, subject to any determination in such
proceeding, severally and respectively be restored to their former positions and
rights under this Security Agreement, and thereafter all rights, remedies and
powers of the Collateral Agent shall continue as though no such proceedings had
been taken.

                      (c)     All rights of action under this Security 
Agreement may be enforced by the Collateral Agent without the possession of any
instrument evidencing any Obligation or the production thereof at any trial or
other proceeding relative thereto, and any suit or proceeding instituted by the
Collateral Agent shall be brought in its name and any judgment shall be held as
part of the Collateral.

         5.9          Waiver and Estoppel.

                      (a)     The Company, to the extent it may lawfully do so,
on behalf of itself and all who may claim through or under it, including without
limitation any and all subsequent creditors, vendees, assignees and lienors,
waives and releases all rights to demand or to have any marshalling of the
Collateral upon any sale, whether made under any power of sale granted herein or
pursuant to judicial proceedings or upon any foreclosure or any enforcement of
this Security Agreement and consents and agrees that all the Collateral may at
any such sale be offered and sold as an entirety.

                      (b)     The Company, to the extent it may lawfully do so,
waives presentment, demand, protest and any notice of any kind (except notices
explicitly required hereunder) in connection with this Security Agreement and
any action taken by the Collateral Agent with respect to the Collateral.

         5.10         Power of Attorney.

         The Company hereby irrevocably constitutes and appoints the Collateral
Agent, with full power of substitution, as its true and lawful attorney-in-fact
with full irrevocable power and authority in the place and stead of the Company
and in the name of the Company, or any of them, or in its own name, from time to
time in the Collateral Agent's reasonable discretion for the purpose of carrying
out the terms of this Security Agreement at any time (i) upon an occurrence of
an Event of Default and during the continuance thereof, or (ii) in the event the

Company, or any of them, fails to promptly perform any of its or their
obligations under this Security Agreement following the Collateral Agent's
demand for such performance, to take any and all appropriate action and to
execute any and all documents and instruments which may be necessary or
desirable to accomplish the purposes of this Security Agreement and, without
limiting the generality of the foregoing, hereby gives the Collateral Agent the
power and right, on behalf of the Company, without notice to or assent by the
Company to do the following:

                      (a)     to pay or discharge taxes, liens, security 
interests or other encumbrances levied or placed on the Collateral;

                      (b)     to effect any repairs or any insurance called for
by the terms of this Security Agreement and to pay all or any part of the
premiums therefor and the costs thereof; and

                      (c)     upon the occurrence and continuance of any Event 
of Default, (i) to direct any party liable for any payment under any of the
Collateral to make payment of any and all moneys due and to come due thereunder
directly to the Collateral Agent or as the Collateral Agent shall direct; (ii)
to receive payment of and receipt for any and all moneys, claims and other
amounts due and to become due at any time in respect of or arising out of any
Collateral; (iii) to sign and endorse any invoices, freight or express bills,
bills of lading, storage or warehouse receipts, drafts against debtors,
assignments, verifications and notices in connection with accounts and other
documents relating to the Collateral; (iv) to commence and prosecute any suits,
actions or proceedings at law or in equity in any court of competent
jurisdiction to collect the Collateral or any thereof and to enforce any other
right in respect of any Collateral; (v) to defend any suit, action or proceeding
brought against the Company, or any of them, with respect to any Collateral;
(vi) to settle, compromise and adjust any suit, action or proceeding described
above and, in connection therewith, to give such discharges or releases as the
Collateral Agent may deem appropriate; (vii) to assign any Patent or Trademark
(along with the goodwill of the business to which such Trademark pertains), for
such term or terms, on such conditions, and in such manner, 

                                      26

<PAGE>

as the Collateral Agent shall in its sole discretion determine; and (viii)
generally to sell, transfer, pledge, make any agreement with respect to or
otherwise deal with any of the Collateral as fully and completely as though the
Collateral Agent were the absolute owner thereof for all purposes, and to do, at
the Collateral Agent's option and the Company's expense, at any time, or from
time to time, all acts and things which the Collateral Agent deems necessary to
protect, preserve or realize upon the Collateral and the Collateral Agent's
security interest therein, in order to effect the intent of this Security
Agreement, all as fully and effectively as the Company might do.

         The Company hereby ratifies all that said attorneys shall lawfully do
or cause to be done by virtue hereof. This power of attorney is a power coupled
with an interest and shall be irrevocable.


         5.11         Application of Proceeds.

         All proceeds realized by the Collateral Agent in respect of any or all
of the Collateral, including the proceeds of any sale thereof or any cash
distributed in respect of any of the Collateral shall be applied against the
Obligations in accordance with the Indenture. To the extent permitted by
applicable law, the Company shall be liable for any deficiency, and any surplus
shall be returned by the Collateral Agent to the person or persons legally
entitled thereto.

termination.
