                               EXPLANATORY NOTES
   
  All historical share and per share information has been removed from this
registration statement (the "Registration Statement") pending a proposed
reverse stock split that Communications Systems International, Inc. ("CSI")
intends to effectuate in order to comply with the listing requirements of The
Nasdaq Stock Market, Inc. Upon the determination of the reverse stock split
ratio, this Registration Statement will be amended to include all such share
and per share information.     
          
  This Registration Statement contains two prospectuses: one related to the
offering of     shares of Common Stock (the "Common Stock") by CSI (the
"Prospectus"); and one relating to the offering of shares of Common Stock by
certain selling Securityholders (the "Selling Securityholders' Prospectus").
The exact number of Selling Securityholders' Shares to be registered cannot be
determined until CSI effects its proposed reverse stock split. Following the
Prospectus are certain substitute pages of the Selling Securityholders'
Prospectus, including alternate front outside and back outside cover pages, an
alternate "The Offering" section of the "Prospectus Summary" and sections
entitled "Concurrent Offering" and "Plan of Distribution." Each of the
alternate pages for the Selling Securityholder Prospectus included herein is
labeled "Alternate Page for Selling Securityholders' Prospectus" or
"Additional Page for Selling Securityholders' Prospectus." All other sections
of the Prospectus, other than "Underwriting" and "Concurrent Offering," are to
be used in the Selling Securityholders' Prospectus. In addition, cross-
references in the Prospectus will be modified in the Selling Securityholders'
Prospectus to refer to the appropriate sections.

  All of the shares of Common Stock offered hereby are being sold by
Communications Systems International, Inc. ("CSI"). The Common Stock is
currently traded on the OTC Bulletin Board under the symbol "CSYG." Prior to
the offering, there has been a limited public market for the Common Stock of
CSI. On      , 1998, the closing bid price of the Common Stock was $     per
share. See "Price Range of Common Stock." It is currently estimated that the
public offering price will be between $     and $     per share. See
"Underwriting" for a discussion of factors to be considered in determining the
offering price. Application has been made to have the Common Stock approved for
quotation on the Nasdaq SmallCap Market under the symbol "CSGL." Following
quotation on the Nasdaq SmallCap Market, the Common Stock will no longer be
quoted on the OTC Bulletin Board.     
   
  Concurrent with the offering,    shares of Common Stock are being registered
for offer and sale by certain Securityholders (collectively, the "Selling
Securityholders") of the Company. Such shares consist of a maximum of 113,600
shares of Common Stock that were issued in a private placement completed in
December 1997 and      shares issuable upon the exercise of certain warrants
(collectively, the "Selling Security- holders' Shares"). The Selling
Securityholders' Shares are not part of the underwritten offering. Other than
receipt of the exercise price of certain warrants, the Company will not receive
any proceeds from the sale of the Selling Securityholders' Shares. In addition,
the Selling Securityholders have agreed with the Representatives not to sell or
transfer the Selling Securityholders' Shares for a period of 180 days following
the date of this Prospectus.

                                THE COMPANY     
       
   
  The Combined Company is a growing provider of international
telecommunications services offering long distance, calling cards and enhanced
voice and data services. With more than 25,500 customers in over 170 countries,
the Combined Company primarily serves markets that have been historically
underserved by large telecommunications providers and incumbent telephone
operators ("ITOs"). The Combined Company presently focuses on international
call-reorigination, capitalizing on the arbitrage opportunity created by
differences between U.S. and international long-distance rates. Going forward,
the Combined Company intends to leverage the expertise derived from its call-
reorigination business, and capitalize on the established customer base
generated by its call-reorigination business, to provide higher margin
telecommunications services such as call-through, enhanced fax and business
grade Internet services.     
   
  The world's larger telecommunications carriers, such as AT&T, MCI, British
Telecom, Deutsche Telecom AG and France Telecom, have focused on developed
telecommunications markets that are characterized by high teledensity (ratio of
telephone lines to inhabitants), an advanced stage of deregulation, a large
volume of international telecommunications traffic and a concentration of
multinational corporations. These markets include the United States, the United
Kingdom, Germany, France and Japan. The Combined Company focuses on what it
characterizes as emerging telecommunications markets, which are (i) smaller
developed countries such as Argentina, Austria, Brazil, Switzerland, Ireland,
Singapore and South Africa, and (ii) markets that typically have less developed
telecommunications infrastructures, are in an earlier stage of deregulation and
have more monopolistic distribution profiles. Based on data from the
International Telecommunications Union, the Combined Company has calculated
that the approximately 145 countries that the Combined Company targets as
emerging telecommunications markets generated approximately 23.0 billion
minutes in outgoing international telecommunications traffic in 1995.     
   
  The Combined Company's telecommunications services are marketed and sold
through a network of independent sales agents, strategic relationships and in-
house direct marketing. The Combined Company relies primarily on over 170
independent sales agents that cover over 170 countries. GlobalTel has an
exclusive agreement with the International Business Network for World Commerce
and Industry, Ltd. ("IBNET"), the managing member of the Consortium of Global
Commerce, under which IBNET will market the services of GlobalTel, and
ultimately the Combined Company, through several thousand individual chambers
of commerce located in over 200 countries. In addition, GlobalTel has a
strategic relationship with Novell that provides it with a distribution channel
for its services, and ultimately those of the Combined Company, through a
select number of Novell's network of over 25,000 value-added resellers.     
   
  The Combined Company has a broad customer base including foreign offices of
multinational corporations, including Nike Inc., Microsoft Corporation,
Mitsubishi Corporation and Chrysler Corporation; major international hotels,
including the Inter-Continental Hotel and the Copacabana Palace in Rio de
Janeiro, Brazil and Southern Sun Group's Holiday Inn Hotels in South Africa;
and embassies and international agencies, including the United States embassies
in Chile, Korea, Australia and the Ukraine and the United Nations consulate in
South Africa.     
       
                                       1
<PAGE>
 
   
  The Combined Company provides telecommunications services through its (i)
voice switching and global fax messaging infrastructure in Los Angeles,
California, (ii) voice switching and billing center in Ft. Lauderdale, Florida,
(iii) access to third party infrastructure through international
telecommunications carriers and through Equant, a global data network services
provider, and (iv) enhanced fax nodes in Hong Kong and Mexico City. The
Combined Company uses both off-the-shelf technologies, which provide
flexibility to adapt to the rapidly changing telecommunications environment,
and proprietary automated call processing technologies (DIAL and LINK-US),
which enhance the Combined Company's competitive position in serving high
volume customers.     
          
  The principal components of the Combined Company's strategy are to (i)
increase penetration of emerging telecommunications markets by capitalizing
upon its call-reorigination experience, strategic marketing relationships and
proprietary technologies, (ii) pursue and implement additional strategic
acquisitions of complementary international customer bases, products and
infrastructure, (iii) exploit strategic marketing relationships to expand its
customer base and establish new relationships with independent ISPs and other
network providers in its target markets, (iv) provide an increasingly broad
range of services, such as enhanced voice and data services and a suite of
business grade Internet services, (v) employ flexible open architecture
technology that is modular, scalable and allows for the integration of a
variety of technologies, (vi) utilize proprietary call processing technologies
to provide quality telecommunications services to high volume customers, (vii)
increase revenue through targeted growth in its carrier and reseller business,
and (viii) exploit operating and marketing synergies and efficiencies resulting
from the GlobalTel Merger and the ITC Acquisition.     
          
  CSI is a Colorado corporation formed in April 1993. The Combined Company
intends to change its name to "CS GlobalTel, Inc." upon completion of the
GlobalTel Merger. The Combined Company's executive offices are located at 8
South Nevada Avenue, Colorado Springs, Colorado 80903, and its telephone number
is (719) 471-3332. The Combined Company's Internet address is
http://www.csil.com.     
   
  Unless otherwise indicated, the information contained in this Prospectus (i)
assumes no exercise of the Underwriters' over-allotment option or outstanding
options, warrants or convertible securities, and (ii) gives effect to a
proposed 1 for     reverse stock split that will be completed prior to the date
of this Prospectus. CSI has entered into an agreement in principle to merge
(the "GlobalTel Merger") with GlobalTel, CSI has entered into an agreement to
acquire all of the outstanding stock of ITC (the "ITC Acquisition"), which is
expected to occur simultaneously with the completion of this offering.
References to the present action of the Combined Company refer to activities or
matters that are common to each of CSI, GlobalTel and ITC as of the date of
this Prospectus. Statements regarding prospective activities or matters
relating to the Combined Company refer to activities that may be undertaken or

                                 RISK FACTORS
   
  In addition to the other information contained in this Prospectus, the
following risk factors should be considered carefully in evaluating the
Combined Company and its business before purchasing shares of Common Stock
offered hereby. This Prospectus contains certain forward-looking statements
that involve substantial risks and uncertainties. When used in this
Prospectus, the words "may," "will," "expect," "anticipate," "continue,"
"estimate," "project," "intend," "believe" and similar expressions are
intended to identify forward-looking statements within the meaning of Section
27A of the Securities Act of 1933 (the "Securities Act") and Section 21E of
the Exchange Act regarding events, conditions and financial trends that may
affect the Combined Company's future plan of operations, business strategy,
operating results and financial position. Prospective investors are cautioned
that any forward-looking statements are not guarantees of future performance
and are subject to risks and uncertainties and that actual results could
differ materially from the results expressed in or implied by these forward-
looking statements as a result of various factors, many of which are beyond
the Combined Company's control. These factors are described under the headings
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business" and in the risk factors set forth below.     
 
RISKS RELATED TO THE COMBINED COMPANY AND THE TELECOMMUNICATIONS INDUSTRY
   
LIMITED OPERATING HISTORY; SUBSTANTIAL AND CONTINUING LOSSES; SUBSTANTIAL
DOUBT ABOUT THE ABILITY TO CONTINUE AS GOING CONCERNS     
   
  Both CSI and ITC commenced operations in 1993 and GlobalTel commenced
operations in 1995. Accordingly, CSI, GlobalTel and ITC have limited operating
histories upon which an evaluation of their performance can be based. The
Combined Company has no combined operating history. The Combined Company's
prospects must be considered in light of the risks, expenses and difficulties
frequently encountered by companies in their early stage of operations. There
is no assurance that the Combined Company will operate profitably or be
successful in capitalizing on perceived synergies. CSI has incurred
significant losses, including losses of approximately $2.5 million and
$259,000 during the 12 months ended April 30, 1996 and 1997, respectively, and
a loss of approximately $770,000, during the nine months ended January 31,
1998, resulting in an accumulated deficit of approximately $4.8 million as of
January 31, 1998. GlobalTel has incurred significant losses, including losses
of $5.9 million and $7.8 million for the 12 months ended December 31, 1996 and
1997, respectively, resulting in an accumulated deficit of $15.6 million as of
December 31, 1997. In addition, ITC incurred a loss of approximately $850,000
during the 10 months ended October 31, 1997. Losses may continue until such
time, if ever, that the Combined Company is able to generate a level of
revenue sufficient to offset its cost structure. There can be no assurance
that the Combined Company will achieve significantly increased revenue or
profitable operations. The Combined Company's results of operations may be
below the expectations of public market analysts and investors in future
quarters, which would likely result in a decline in the trading price for the
Common Stock. CSI's and GlobalTel's independent auditors have each included an
explanatory paragraph in their respective reports on the financial statements
stating that they have been prepared assuming that each of CSI and GlobalTel,
respectively, will continue as separate going concerns. However, recurring
losses from operations and projected future cash requirements raise
substantial doubt about each company's ability to continue as a going concern.
The explanatory paragraphs in the reports on the financial statements do not
consider the proposed consummation of this offering. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
the Financial Statements.     
   
GLOBALTEL BILLING SYSTEM AND INTERNAL CONTROLS     
   
  In November 1997, GlobalTel commenced using a new billing system to record
revenue from calls made by GlobalTel's customers and the application of cash
receipts to customer accounts. In connection with auditing GlobalTel's 1997
financial statements, GlobalTel's independent auditors identified a material
weakness in GlobalTel's internal accounting controls with respect to the
administration of the billing system that could, if not corrected, lead to
errors in revenue reporting which may not be detected by management of
GlobalTel on a timely     
 
                                       5
<PAGE>
 
   
basis. GlobalTel intends to eliminate this material weakness by outsourcing
the administration of its billing system to its billing system vendor until
the completion of the GlobalTel Merger, at which time GlobalTel's billing
functions will be transferred to the Combined Company's billing system. There
can be no assurance that this or other control deficiences will not occur in
the future. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."     
   
NEED FOR ADDITIONAL CAPITAL AND CAPITAL REQUIREMENTS     
   
  The efforts of CSI, GlobalTel and ITC to develop and introduce an array of
enhanced telecommunications services have required, and will continue to
require, the Combined Company to invest in network infrastructure and systems
development. Also, the Combined Company has incurred substantial pro forma
losses and expects to continue to incur losses due, in part, to significant
depreciation and amortization expense, through the foreseeable future. At
January 31, 1998, CSI and ITC, and at December 31, 1997, GlobalTel,
respectively, had working capital deficits of approximately $3.0 million, $1.4
million and $4.9 million, respectively. The Combined Company believes that,
based upon its present business plan, the net proceeds of this offering,
together with revenue from operations, will be sufficient to finance operating
losses, the development and introduction of enhanced services and to meet its
other currently planned working capital and capital expenditure requirements
through the next 12 months. However, due to the need to continue to expand its
network operations and service offerings and other factors, the Combined
Company expects that it will need to raise additional capital in future
periods. The Combined Company also intends to seek lease financing for a
portion of the equipment and systems that it acquires in 1998 and beyond,
although there can be no assurance that this financing will be available to
the Combined Company when needed or on acceptable terms. If the Combined
Company experiences greater than anticipated capital requirements, if the
implementation of the Combined Company's operating strategy fails to produce
anticipated revenue growth and cash flows, if lease financing is not available
or if additional working capital is required for any other reason, the
Combined Company will be required to obtain additional capital earlier than
currently anticipated. The timing of the need for additional capital
subsequent to the next 12 months also will be affected by the extent to which
the Combined Company's rescission offer is accepted. See "Rescission Offer."
There can be no assurance that the Combined Company will be able to obtain
equity, debt or lease financing when needed or on terms that the Combined
Company finds acceptable. Any issuances of additional equity or convertible
debt may cause substantial dilution to the Combined Company's shareholders. If
the Combined Company is unable to obtain sufficient funds to satisfy its
capital requirements, it will be forced to reduce the scope of its expansion
plans, curtail operations, dispose of assets or seek extended payment terms
from its vendors, any of which could have a material adverse effect on the
Combined Company's business, financial condition and results of operations.
See "Management's Discussion and Analysis of Financial Condition and Results
of Operations."     
   
DEPENDENCE ON KEY INDEPENDENT SALES AGENTS     
   
  CSI currently depends on approximately 42 independent sales agents to sell
its services, including Edward Stoever, who operates in Argentina, and CS do
Brazil. These two independent sales agents accounted for approximately 54.3%,
and 11.5%, respectively, of CSI's revenue in the 12 months ended December 31,
1997, and the ten largest independent sales agents accounted for approximately
91.3% of CSI's revenue in the nine months ended January 31, 1998. GlobalTel
currently depends on 81 independent sales agents to sell its services. The 10
largest independent sales agents accounted for approximately 30.9% of
GlobalTel's revenue in the 12 months ended December 31, 1997. ITC currently
depends on approximately 55 independent sales agents to sell its services,
including Generic Telecom, Inc., Zohair Attoue and Janel Richards
(collectively, with Mr. Stoever and CS do Brazil, the "Key Independent Sales
Agents"). These three independent sales agents accounted for approximately
26.6%, 21.4% and 12.7%, respectively, of ITC's revenue in the 10 months ended
October 31, 1997, and the ten largest independent sales agents accounted for
approximately 89.1% of ITC's revenue in the 10 months ended October 31, 1997.
       
  If the Combined Company fails to retain the services of any of the Key
Independent Sales Agents for any reason or loses the services of other
independent sales agents that contribute significantly to the Combined
Company's revenue, the Combined Company's cash flow and results of operations
would be adversely affected because of expected high customer attrition. The
Combined Company also depends on its independent sales agents and persons
engaged by them to install and service much of the Combined Company's
technologies. The     
 
                                       6

failure of such persons to properly install or service the Combined Company's
systems could adversely affect the Combined Company. Although independent
sales agents are subject to agreements, such agreements may be difficult to
enforce because the independent sales agents are domiciled in foreign
countries. Under the terms of the agreements, independent sales agents are
responsible for collecting customer payments except for credit card payments,
and are generally responsible for customer bad debts less, in some cases, an
allowance granted by the Combined Company. Failure of independent sales agents
to collect and remit customer payments to the Combined Company presents risks
to the Combined Company. CSI's former independent sales agent in Singapore
recently failed to remit aggregate payments of $215,000. CSI is aggressively
pursuing collection of this receivable, although its ultimate recovery is not
assured. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business--Sales and Marketing."     
   
NEED TO INTEGRATE AND MANAGE GLOBALTEL AND ITC; SELECTION AND INTEGRATION OF
UNSPECIFIED ACQUISITIONS     
   
  Management believes that the consummation of the GlobalTel Merger and the
ITC Acquisition will substantially increase the Combined Company's independent
sales agent base, technological capabilities, management expertise and carrier
relationships. The Combined Company's ability to realize any long-term
advantages from the GlobalTel Merger and the ITC Acquisition will depend in
large part on successfully integrating, managing and improving the operations
of GlobalTel and ITC. The Combined Company's management team has no experience
in integrating acquired companies. Risks relating to such integration include
the risk of loss of services of executive officers, including Ronald P.
Erickson and Philip A. Thomas, the loss of independent sales agents of the
Combined Company or adverse changes in strategic or carrier relationships.
There can be no assurance that CSI will be able to successfully integrate
GlobalTel or ITC, the failure of which would have a material adverse effect on
the business of the Combined Company.     
   
  A key element of the Combined Company's strategy is expansion through the
additional acquisitions of complementary international customer bases,
products and infrastructure. Except for the GlobalTel Merger agreement in
principle and the ITC Acquisition agreement, the Combined Company has no
agreements, arrangements or understandings for any such acquisition as of the
date of this Prospectus. There can be no assurance that the Combined Company
will be successful in identifying appropriate acquisition opportunities or
negotiating favorable terms. In most cases, the Combined Company will not be
required to obtain shareholder approval in order to complete its acquisitions.
Under the Colorado Business Corporation Act, a corporation may effect a merger
with or an acquisition of another company without shareholder approval if the
corporation will be the surviving entity, the articles of incorporation of the
corporation are not substantively amended, each shareholder will hold the same
number and type of shares after the transaction as he did before, and the
outstanding shares of the corporation will not be increased by more than 20%
as a result of the transaction. Any future acquisitions or related activity
will involve additional risks including, among others, the difficulty of
identifying appropriate acquisition candidates, the difficulty of assimilating
the operations and personnel of the respective entities, the potential
disruption of the Combined Company's ongoing business and the inability of
management to capitalize on the opportunities presented by the acquisitions.
In addition, the failure to successfully incorporate acquired technology and
rights into the Combined Company's services, the inability to maintain uniform
standards, controls, procedures and policies, the impairment of relationships
with employees and customers as a result of changes in management and an
increase in amortization of intangible assets in the Combined Company's
financial statements may adversely affect the Combined Company. If the
Combined Company completes acquisitions through the issuance of Common Stock,
the ownership interest of existing holders would be decreased. There can be no
assurance that the Combined Company will be able to finance any future
acquisitions.     
   
  The successful integration of any such acquisition is critical to the future
financial performance of the Combined Company. Complete integration of any
acquisitions could take several fiscal quarters to accomplish and would
require, among other things, coordination of the respective companies' sales,
marketing and technical development efforts. The integration process may cause
management's attention to be diverted from operating the Combined Company, and
any difficulties encountered in the transition process could have an adverse
impact on the business, financial condition and results of operations of the
Combined Company. There can be no assurance that present and potential
customers of the Combined Company and any acquired entity would     
 
                                       7
<PAGE>
 
   
continue their historic usage patterns without regard to the acquisition, and
any significant delay or reduction in usage could have an adverse effect on
the Combined Company's business, financial condition and results of
operations.     
   
  The difficulty of combining companies may be increased by geographic
distances between companies and the need to integrate personnel. Changes
brought about by any acquisition may cause key employees, independent sales
agents, or carriers to terminate their relationships with the Combined
Company. There can be no assurance that the Combined Company will retain the
employees, independent sales agents and carrier relationships of an acquired
entity or that the Combined Company will realize any of the other anticipated
benefits of any acquisition. There can be no assurance that costs of combining
potential acquisitions will not have an adverse effect upon the Combined
Company's operating results. There can be no assurance that, following any
acquisition, the Combined Company will be able to operate any acquired
business on a profitable basis.     
   
MANAGEMENT OF GROWTH     
   
  The Combined Company has experienced significant growth in the past two
years and expects such growth to continue. The Combined Company's growth may
place significant strains on the Combined Company's management, staff, working
capital and operating and financial control systems. There can be no assurance
that the Combined Company's management, staff, working capital and systems
will be adequate to support its future anticipated growth. The failure to
recruit qualified staff, to continue to upgrade operating and financial
control systems or to respond effectively to difficulties encountered during
expansion could have a material adverse effect on the Combined Company's
business, financial condition and results of operations.     
   
DEPENDENCE ON CARRIERS AND OTHER SUPPLIERS     
   
  The Combined Company's ability to achieve and maintain profitable operations
is heavily dependent upon the agreements the Combined Company has with certain
international long distance carriers. The Combined Company, among other
things, must negotiate favorable rates with these long distance carriers.
Because of the frequent fluctuations in rates of long distance carriers, the
Combined Company believes that it is in its best interest to have short-term
agreements with its carriers. Most of the Combined Company's agreements with
its carriers will expire, or may be terminated by either party, within one
year, and there can be no assurance that these agreements will be renewed or
that the Combined Company will be able to obtain favorable rates from these or
other carriers. There are a small number of carriers with whom the Combined
Company has carrier agreements. The Combined Company's dependence on
particular carriers will vary because the Combined Company shifts its use of
carriers depending on the rates offered. The Combined Company periodically
renegotiates rates with its current carriers and seeks to establish
relationships with new long distance carriers that provide the most favorable
rates. The Combined Company's ability to obtain favorable rates from the
carriers depends, in large part, on the Combined Company's total volume of
long distance traffic. There is no guarantee that the Combined Company will be
able to maintain the volume of international long distance traffic necessary
to obtain favorable rates. The loss of any carrier could have a material
adverse effect on the Combined Company.     
   
  Due to its financial condition, CSI defaulted on payment obligations to
certain carriers in 1995, 1996 and 1997. Although CSI was able to negotiate
deferred payment arrangements with these carriers (and thereafter made such
deferred payments) and was able to continue purchasing minutes from certain of
these carriers, there is no assurance that it will be able to make such
arrangements with these or other carriers if required in the future. As of
March 31, 1998, CSI was in arrears on payments due to one carrier of
approximately $780,000. In October 1997, GlobalTel failed to pay amounts due
to one of its principal long distance carriers within the time period that
this carrier customarily had required payment. As a result, this carrier
ceased providing services to GlobalTel and, under the terms of its agreement
with GlobalTel, could demand a termination payment of up to $1.2 million.
GlobalTel was able to re-route traffic that previously had been carried by
this carrier without any interruption in service to GlobalTel's customers. In
December 1997, after GlobalTel paid this carrier a substantial portion of the
amounts past due, services were restored. GlobalTel has negotiated payment
terms on the     
 
                                       8
<PAGE>
 
   
remaining balance owed and does not believe that it will be required to pay an
amount in excess of that owed for carrier services provided. As of March 31,
1998, GlobalTel was in arrears on approximately $641,000 due to this carrier.
There can be no assurance that GlobalTel will not be required to pay a penalty
to this or any other supplier or that the Combined Company will not be in
default of its obligations to its suppliers in the future. In addition, in
November 1997, WorldCom, Inc. ("WorldCom") commenced an action against ITC in
Connecticut state court seeking damages of approximately $1.1 million for
alleged past due carrier bills. ITC recorded a $1.1 million charge against
earnings in the ten month period ended October 31, 1997. ITC believes it has
meritorious defenses to the suit. ITC intends to vigorously defend its
position and will attempt to reach a settlement with this carrier.     
   
  Under certain carrier contracts, the Combined Company obtains rate
commitments (subject to adjustment, as provided in each carrier contract),
which are generally more favorable than otherwise would be available by
committing to purchase a minimum number of minutes from such carriers. If the
Combined Company fails to meet its minimum requirements under a carrier
contract, it could still be required to pay some or all of its minimum monthly
commitment as a penalty. Historically, CSI failed to meet required minimum
purchases and incurred unused usage charges from AT&T and MCI. The Combined
Company's aggregate minimum monthly commitments currently are approximately
$550,000, which represent approximately 23.5% of the Combined Company's
average monthly cost of revenue for the 12 months ended December 31, 1997.
Failure to maintain favorable carrier contracts would increase the Combined
Company's cost of revenue and the ability to achieve and maintain
profitability. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business."     
   
  A failure by a carrier to deliver quality services or products on a timely
basis, or the inability of the Combined Company to develop alternative
suppliers if and as required, could result in delays in the provision of
service to the Combined Company's customers which could have a material
adverse effect on the Combined Company. The Combined Company's remedies
against carriers that fail to deliver services or products on a timely basis
are limited, in certain cases, by the Combined Company's desire to maintain
relationships with its key carriers. In addition, as the Combined Company's
carriers upgrade their technology, the Combined Company may encounter
difficulties in integrating new technology into the Combined Company's
network.     
   
  The Combined Company is dependent on certain third-party suppliers of
equipment and hardware components, including its integrated computer systems
and switching platforms, and expects that it will become more dependent on
such suppliers as its business expands. A failure by a supplier to deliver
quality products on a timely basis, or the inability to develop other sources
of supply if required, could result in delays that could adversely affect the
Combined Company. In addition, the Combined Company's business is highly
dependent on its computer systems, telephone equipment and software. See
"Business."     
   
RECENT INTRODUCTION AND ONGOING DEVELOPMENT OF ENHANCED SERVICES     
   
  Substantially all of the Combined Company's revenue to date has been derived
from international call- reorigination services and reselling international
long distance minutes to other carriers and resellers. The Combined Company
believes that as deregulation occurs and competition increases in markets
around the world, the pricing advantage of traditional call-reorigination
relative to conventional international long-distance service will diminish. In
order to maintain its existing customer base, attract new customers and
increase its revenue, the Combined Company must offer a variety of enhanced
telecommunications services, as well as its own call-through service, at
competitive prices. Accordingly, the Combined Company is in the process of
developing a number of enhanced telecommunications services such as fax and
business grade Internet services. The first of these enhanced services was
offered to GlobalTel's customers in November 1997. To date GlobalTel has not
generated significant revenue from these services. Several other new services
described in this Prospectus are still under development and are not scheduled
for implementation until various times in 1998 or later. It is not uncommon
for the introduction of new telecommunications services to be delayed or
occasioned by technical problems. There can be no assurance that the Combined
Company will not encounter delays or technical problems in the introduction of
new services which will inhibit the Combined Company's ability to compete.
Also, there can be no assurance that the Combined Company will have sufficient
capital to complete development     
 
                                       9
<PAGE>
 
   
and introduction of all of the enhanced services that it currently plans to
offer to its customers or that the introduction of such services will result
in increased revenue. The failure to introduce enhanced telecommunications and
Internet-related services, failures in the systems that would deliver those
services or the absence of demand for such services when introduced would have
a material adverse effect on the Combined Company's ability to achieve or
sustain profitability in the future. See "Business--Services."     
   
DEPENDENCE ON NEW NETWORK SYSTEMS     
   
  The Combined Company's success is dependent upon its ability to deliver high
quality, uninterrupted telecommunications services. During 1997, GlobalTel
installed new switching software and hardware in its Los Angeles switching
center. These facilities did not commence carrying customer traffic until the
fourth quarter of 1997. Prior to implementing these new systems, virtually all
of GlobalTel's revenue was attributable to international call-reorigination
services and sales to carriers. Accordingly, successful implementation and
reliable operation of these new systems is essential to the Combined Company's
operations. Under terms of its Reciprocal Telecommunications Agreement with
ITC, CSI transferred its telecommunications traffic to ITC's switching center
in Ft. Lauderdale in early 1998. This transfer occurred after CSI technicians
upgraded ITC's switches to accept Internet triggering of its call-
reorigination services. There can be no assurance that these recently
installed systems and system upgrades will be adequate to perform their
intended functions or that the Combined Company will not suffer adverse
consequences in connection with their implementation. For example, there can
be no assurance that the Combined Company will not encounter material delays
in the introduction or provisioning of new services to new or existing
customers. There also can be no assurance that the Combined Company will not
encounter difficulties in enhancing, or integrating new technology into, its
systems. The inability of the Combined Company to implement any required
system enhancement, to acquire new systems or to integrate new technology in a
timely and cost effective manner could have a material adverse effect on the
Combined Company's business, financial condition and results of operations.
See "Business--Services" and "--Network and Operations."     
 
CHANGING INDUSTRY ENVIRONMENT
   
  The majority of the Combined Company's operations involve the international
call-reorigination industry. This industry operates under the guidelines of
multiple foreign and domestic government regulations. If the Combined Company
should lose the authorization to offer call-reorigination services in any of
its current markets, the results of operations of the Combined Company could
be materially adversely affected. The call-reorigination industry is based
upon the arbitrage opportunities created by higher international calling rates
charged by ITOs compared to rates charged by U.S.-based long distance
carriers. However, ITOs may lower their international calling rates, thereby
eliminating or severely affecting the market for call-reorigination services.
Representatives of 69 countries, including the United States, recently entered
into an agreement with the World Trade Organization ("WTO"), which became
effective on February 5, 1998, with the goal of increasing competition among
telecommunications providers in those markets. If some or all of the ITOs
operating in the Combined Company's current markets lower their rates, the
results of operations of the Combined Company in those markets would be
adversely affected. In addition, certain European countries have enacted or
have proposed enacting a value added tax (VAT) on international call-
reorigination services. In February 1997, the government of Argentina enacted
legislation that simultaneously lowered the international long distance
calling rates from Argentina and increased the domestic rates within
Argentina. Historically, the Combined Company has received a significant
portion of its revenue from customers in Argentina. To date, this legislation
has not had an adverse effect on the Combined Company's results of operations
because the rates charged by Argentina's ITOs remain higher than the Combined
Company's rates. There can be no assurance such an adverse effect will not
occur in the future as a result of this or other legislation. See "Business."
    
       
COMPETITION
   
  General. The Combined Company faces a high level of competition for
customers and independent sales agents in all of its markets, and expects
competition to intensify in the future. There are no substantial barriers to
entry in the call-reorigination industry. The Combined Company believes that
there are more than 150 companies     
 
                                      10
<PAGE>
 
   
engaged in the international call-reorigination business. Many of the Combined
Company's competitors are significantly larger, have substantially greater
financial, technical and marketing resources, larger networks and a broader
portfolio of services than the Combined Company. Additionally, many
competitors have strong name recognition and brand loyalty, long-standing
relationships with the Combined Company's target customers, and economies of
scale that can result in a lower relative cost structure compared to the
Combined Company.     
   
  Competition for customers and independent sales agents in the
telecommunication markets in which the Combined Company operates is on the
basis of price, type and quality of services offered. Increased competition
could force the Combined Company to reduce its prices and profit margins if
the Combined Company's competitors are able to procure rates or enter into
service agreements comparable to or better than those the Combined Company
obtains or if competitors are able to offer other incentives to existing and
potential customers and independent sales agents. Similarly, the Combined
Company has no control over the prices set by its competitors in the long
distance market. The Combined Company is aware that its ability to market its
long distance services depends upon the existence of spreads between the rates
offered by the Combined Company and those offered by the carriers with which
it competes as well as those from which it obtains service. A decrease in such
spreads or price competition in the Combined Company's markets could have a
material adverse effect on the Combined Company's business, financial
condition and results of operations.     
          
  Other potential competitors include cable television providers, wireless
telephone providers, Internet access providers, electric and other utilities
with rights of way, railways, microwave carriers and large end users that have
private networks. The intensity of such competition has recently increased and
the Combined Company believes that such competition will continue to intensify
as the number of new entrants increases. If the Combined Company's competitors
devote significant additional resources to the provision of international long
distance telecommunications services to the Combined Company's target customer
base, the Combined Company could suffer a reduction in revenue which could
have a material adverse effect on the Combined Company's business, financial
condition and results of operations.     
   
  U.S. Based Competition. The large U.S. long distance carriers have, in the
past, been reluctant to compete directly with ITOs by entering the
international call-reorigination business and attempting to capture
significant market share. This is changing and AT&T, among others, is entering
the call-reorigination business. The Combined Company's principal U.S.-based
competitors are providers of international call-reorigination services such as
Access Authority, AT&T, IDT Corporation, Justice Technology Corporation,
International Telecom, Ltd. (Kallback), Telegroup, Inc., USA Global Link,
Inc., UTG Communications International, Inc., Viatel, Inc. and Worldpass
Communications Corp., and as well as providers of traditional long distance
services such as AT&T, Cable & Wireless, Frontier Corp., GTE Communications,
LCI International, Inc., MCI, Qwest Communications International, Inc.,
Sprint, WorldCom, and Regional Bell Operating Companies ("RBOCs") outside
their exchange territories.     
   
  International Based Competition. The Combined Company's principal
international-based competitors include, among others, Telefonica de Argentina
and Telecom Argentina in Argentina; Optus Communications in Australia,
Telebras, Telesp and Telerj in Brazil; France Telecom in France; Deutsche
Telecom AG in Germany; Kokusan Denshin Denwa International Telecom Japan (KDD)
and International Digital Communications in Japan; PTT Telecom B.V. in the
Netherlands; and Telekom S.A. in South Africa; and Cable & Wireless plc,
British Telecommunications plc, Mercury Communications Ltd., AT&T, WorldCom,
Sprint and ACC Corp., Swiftcall Ltd., Oystel Communications, Ltd. and First
Telecom in the United Kingdom. The Combined Company also competes with non-
U.S. based providers of international call-reorigination or other alternative
international long-distance services. The Combined Company believes that ITOs
generally have certain competitive advantages due to their control over local
connectivity and close ties with national regulatory authorities. The Combined
Company also believes that, in certain instances, regulators have shown a
reluctance to adopt policies and grant regulatory approvals that would result
in increased competition for the ITO. If an ITO were to successfully pressure
national regulators to outlaw the provision of call-reorigination services and
prevent the Combined Company from providing its services, the Combined Company
could be denied regulatory approval in certain jurisdictions in which its
services would otherwise be permitted. Any delay in obtaining     
 
                                      11
<PAGE>
 
   
regulatory approval, or failure to obtain regulatory approval, could have a
material adverse effect on the Combined Company's business, financial
condition and results of operations. If the Combined Company encounters anti-
competitive behavior in countries in which it operates (such as an ITO
attempting to block access to call-reorigination services) or if the ITO in
any country in which the Combined Company operates uses its competitive
advantages to the fullest extent, the Combined Company's business, financial
condition and results of operations could be materially adversely affected.
Deregulation and increased competition in international markets could cause
prices for international calls to decrease so much that the Combined Company's
international call-reorigination services would no longer be attractive to
customers. See "Business--Competition" and "--Regulation."     
   
REGULATION     
   
  United States domestic interstate long-distance telecommunications services
are subject to limited regulation by the FCC. Intrastate long distance
services are regulated by state commissions, which have varying requirements.
International call-reorigination services are subject to regulation by both
U.S. and foreign regulators. The United States Federal Communications
Commission ("FCC") has imposed certain restrictions on international call-
reorigination providers, including the requirement that authorized carriers
provide service in a manner consistent with the laws of the countries in which
they operate. Recently, the International Telephone Union ("ITU") agreed that
any country could ban call-reorigination services. The provision of some forms
of call-reorigination is illegal in Uruguay, Venezuela, the Philippines and
certain other countries. In addition, 34 countries, primarily in Central and
South America, the Middle East and Asia (including China), have informed the
FCC that they have banned certain forms of call-reorigination. Call-
reorigination service providers or customers violating these countries' laws
may be subject to fines or penalties. Call-reorigination services in these
countries comprised approximately 10.6% of the Combined Company's revenue in
the 12 months ended December 31, 1997. Currently, the Combined Company
believes that it is not in violation of any country's laws or regulations
related to the provision of international long distance services because it
has either ceased actively recruiting customers or employed alternate, non-
banned forms of call-reorigination in those countries. If the Combined Company
is found to have violated such foreign laws it could be subject to fines,
penalties or revocation of its FCC license. However, regulations could be
adopted by one or more countries that could prevent the Combined Company from
operating in such countries, thereby having a material adverse effect on the
Combined Company's operations. Local laws and regulations differ significantly
among the jurisdictions in which the Combined Company operates, and the
interpretation and enforcement of such laws and regulations are often based on
the informal views of the local ministries which, in some cases, are subject
to influence by ITOs. In addition, failure to interpret accurately the
applicable laws and regulations and the mode of their enforcement in
particular jurisdictions could result in monetary penalties imposed against
the Combined Company that could be significant. There can be no assurance that
the Combined Company has accurately predicted or will accurately predict the
interpretation of foreign laws and regulations or regulatory and enforcement
trends or will be found to be in compliance with all such laws and
regulations. The Combined Company generates a significant portion of its
revenue from customers originating calls in South America, Europe, the Pacific
Rim, Africa, the Middle East and Central America. There can be no assurance
that foreign regulation will not have a material adverse effect on the
Combined Company's business, financial condition and results of operations.
See "Business--Regulation."     
   
  The Combined Company is regulated by the FCC and is currently authorized by
the FCC as a reseller of international long distance telephone services. The
Combined Company has not been the subject of any action by the FCC or any
other regulatory entity that would affect its ability to resell international
long distance services. The FCC has determined that call-reorigination service
using uncompleted call signaling, such as that used by the Combined Company,
does not violate United States or international law, but has held that United
States companies providing such services must comply with the laws of the
countries in which they operate as a condition of such companies' FCC
authorizations. The FCC reserves the right to condition, modify or revoke any
authorizations and impose fines for violations of the Communications Act of
1934, as amended (the "Communications Act"), or the FCC's regulations, rules
or policies promulgated thereunder, or for violations     
 
                                      12
<PAGE>
 
   
of the clear and explicit telecommunications laws of other countries that are
unable to enforce their laws against U.S. carriers. See "Business--
Regulation."     
   
  The Telecommunications Act of 1996 (the "1996 Act") and the WTO Agreement
substantially altered the regulatory framework for the telecommunications
industry for domestic and international telecommunications services. The 1996
Act and the WTO Agreement will require the FCC to conduct a variety of
rulemakings to implement various requirements. The Combined Company cannot
predict the ultimate effects of the WTO Agreement or the 1996 Act upon the
Combined Company's business other than to note that the Combined Company will
not be required to contribute to the FCC's Universal Service fund. Such
contributions could be as much as 4.5% or more of revenue for the calendar
year 1998, and would increase in subsequent years.     
          
LEGAL PROCEEDINGS     
   
  In November 1997, WorldCom commenced an action entitled "WorldCom, Inc. v.
International Telephone Company d/b/a Interglobal Telephone Company" against
ITC in Connecticut state court (Docket No. CV-970407418, Superior Court, J.D.
of New Haven) seeking damages of approximately $1.1 million for alleged past
due carrier bills. Although ITC believes it has meritorious defenses to the
suit, there can be no assurance that it will be successful in such defense.
Failure to successfully defend such suit could have a material adverse effect
on the Combined Company.     
   
RESCISSION OFFER     
   
  Immediately after the closing of this offering, the Combined Company intends
to commence a rescission offer (the "Rescission Offer") in accordance with the
federal securities laws and the securities laws of the State of Washington
(the "Washington Securities Act") with respect to an aggregate of     shares
of Common Stock (the "Rescission Stock"), $350,000 in aggregate principal
amount of promissory notes (the "Rescission Notes") and warrants (the
"Rescission Warrants") to purchase an aggregate of approximately     shares of
Common Stock issued in conjunction with the Rescission Stock and Rescission
Notes. The Rescission Notes, the Rescission Stock and the Rescission Warrants
are hereinafter collectively referred to as the "Rescission Securities." The
Rescission Securities were issued or sold by GlobalTel from 1995 through 1997
to approximately 40 individuals and entities who GlobalTel believes at the
time of purchase were residents of the State of Washington. Following this
offering the Combined Company intends to refile a registration statement
previously filed by GlobalTel relating to the Rescission Offer (the
"Rescission Offer Registration Statement") under the Securities Act.     
   
  GlobalTel believes that the Rescission Securities may have been issued or
sold in violation of the registration requirements of the Washington
Securities Act. As a precaution against potential claims by holders of
Rescission Securities, and without admitting non-compliance with the
Washington Securities Act, the Combined Company plans to offer to rescind such
prior issuances and sales by offering to repurchase the Rescission Securities
at the price paid therefor plus interest at the statutory rate of 8% per annum
from the date of purchase to the expiration of the Rescission Offer. The price
paid will be based upon the price paid for the original security purchased by
the purchaser from GlobalTel, regardless of the type of Rescission Security
currently held by the purchaser. The weighted average price paid for the
Rescission Stock is $    per share. The aggregate price paid for the
Rescission Notes, which are to be repaid from the proceeds of this offering,
is $350,000. See "Use of Proceeds." Each of the Rescission Warrants was issued
in conjunction with Rescission Stock or Rescission Notes and for no separate
consideration. Accordingly, the Rescission Warrants must be surrendered for no
separate consideration if the holder of the related Rescission Securities
elects to accept the Rescission Offer with respect to its Rescission
Securities. The aggregate accrued interest with respect to all of the
Rescission Securities as of June 30, 1998 will be approximately $397,000. If
all holders of Rescission Securities were to accept the Rescission Offer, the
Combined Company would be required to make payments aggregating approximately
$3.2 million, plus the aggregate amount of any additional interest thereon
that accrues after June 30, 1998. The Rescission Offer will expire 15 days
after the offer is transmitted. The Combined Company currently expects to use
a portion of the proceeds from this offering to make payments under the
Rescission Offer, if any are required. Offerees who do not accept the
Rescission Offer will thereafter hold     
 
                                      13
<PAGE>
 
   
registered Rescission Securities under the Securities Act which, in the case
of the Rescission Stock, will be freely tradeable by non-affiliates in the
public market as of the effective date of the Rescission Offer Registration
Statement.     
   
  As of the date hereof, GlobalTel is not aware of any claims for rescission
against GlobalTel. Also, current and former officers and directors of
GlobalTel holding an aggregate of $1.4 million (including statutory interest
accrued thereon as of June 30, 1998) of the Rescission Securities have
indicated their intent not to accept the Rescission Offer, although no formal
Rescission Offer has been made to them and they have not and may not agree to
reject the Rescission Offer until the Rescission Offer Registration Statement
has been declared effective by the Securities and Exchange Commission and the
Rescission Offer has commenced. There can be no assurance that all or a
substantial portion of the Rescission Securities will not be tendered in
response to the Rescission Offer. Use of a portion of the proceeds of this
offering in connection with the Rescission Offer will reduce the amount of
working capital available to the Combined Company and require it to seek
additional capital sooner than otherwise might be required. The Rescission
Offer is being made in order to limit, so far as may be permitted under
applicable federal and state securities laws, the potential liability of the
Combined Company with respect to the offer and sale of the Rescission
Securities. Although the Combined Company believes that the offer and sale of
the Rescission Securities were made in compliance with the registration
requirements of federal securities laws, if a holder of the Rescission
Securities were to assert a claim that the Rescission Securities were sold in
violation thereof, the position of the Securities and Exchange Commission is
that liabilities under the federal securities laws are not terminated by
making a rescission offer. Furthermore, notwithstanding the Rescission Offer,
there can be no assurance that the Combined Company will not be subject to
penalties or fines relating to past securities issuances or that other holders
of the Combined Company's securities will not assert or prevail in claims
against the Combined Company for rescission or damages under state or federal
securities laws. See "Use of Proceeds," "Rescission Offer," "Shares Eligible
for Future Sale" and Note 6 of Notes to GlobalTel's Consolidated Financial
Statements.     
   
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS     
   
  The Combined Company's strategy is to focus on international markets. In
many emerging telecommunications markets in which the Combined Company seeks
to market its services, ITOs control access to the local networks, enjoy
better brand recognition and customer loyalty and possess significant
operational economies, including operating agreements with other ITOs.
Moreover, an ITO may take many months before allowing competitors, such as the
Combined Company, to interconnect to its switches within the target market.
There can be no assurance that the Combined Company will be able to obtain the
permits and operating licenses required to operate, access transmission
facilities or market and sell competitive services in its markets. In
addition, pursuit of international growth opportunities may require
significant investments for extended periods before returns, if any, on such
investments are realized.     
   
  The Combined Company's operations also will be subject to a wide range of
general business risks associated with international operations, including
unexpected changes in legal and regulatory requirements; changes in tariffs,
exchange rates and other barriers; political and economic instability;
restrictions on repatriation of funds or profits from foreign markets; long
accounts receivable payment cycles in certain countries; difficulty in
protecting the Combined Company's intellectual property; potentially adverse
tax consequences and the regulation of ISPs by foreign regulatory authorities.
       
  Although the Combined Company's sales to date have been denominated in U.S.
dollars, the value of the U.S. dollar in relation to foreign currencies also
may adversely affect the Combined Company's results of operations. To the
extent the Combined Company changes its pricing practices to denominate prices
in foreign currencies, the Combined Company will be exposed to increased risks
of currency fluctuation. Any such fluctuation could have a material adverse
effect on the Combined Company's earnings or assets when translated into U.S.
dollars. Although the Combined Company has not entered into foreign exchange
contracts to hedge exchange transactions, it may do so in the future.
Additionally, the Combined Company generally will be subject to taxes in
foreign countries where the Combined Company operates. The Combined Company's
ability to claim a foreign tax credit against its U.S. federal income taxes is
subject to various limitations that could result in a     
 
                                      14
<PAGE>
 
   
high effective tax rate on the Combined Company's earnings, if any. There can
be no assurance that laws or administrative practice relating to taxation,
foreign exchange or other matters in countries in which the Combined Company
operates or will operate will not change in a manner adverse to the Combined
Company. There can be no assurance that such factors will not have a material
adverse effect on the Combined Company's business, financial condition and
results of operations.     
   
  The Combined Company is subject to the Foreign Corrupt Practices Act
("FCPA"), which generally prohibits U.S. companies and their intermediaries
from bribing foreign officials for the purpose of obtaining or keeping
business. The Combined Company may be exposed to liability under the FCPA as a
result of past or future actions taken without the Combined Company's knowledge
by independent sales agents, strategic partners and other intermediaries. Any
liability incurred by the Combined Company under the FCPA could be material.
       
RAPID CHANGES IN TECHNOLOGY     
   
  The telecommunications industry is characterized by rapidly changing
technology, evolving industry standards, emerging competition and frequent new
service introductions. Examples of some newly developed telecommunications
technologies include satellite-based transmission systems such as those
proposed by Iridium World Communications Ltd., GlobalStar Telecommunications
Limited and Teledesic Corporation, utilization of the Internet for voice and
data transmission, and digital wireless communications systems. The Combined
Company has invested significantly in sophisticated and specialized
telecommunications and computer technologies such as LINK-US and DIAL. The
Combined Company anticipates that it will be necessary to continue to select,
invest in and develop new and enhanced technology on a timely basis in order to
maintain its competitiveness. The Combined Company's future success will also
depend, in part, on its ability to continue to evolve and adapt
telecommunications technology solutions that keep pace with changing customer
demands. There can be no assurance that the Combined Company can successfully
identify new service opportunities and develop and bring new services to market
in a timely and cost-effective manner, or that services or technologies
developed by others will not render the Combined Company's services or
technologies noncompetitive or obsolete. In addition, there can be no assurance
that service developments or enhancements introduced by the Combined Company
will achieve or sustain market acceptance or that the Combined Company's
technologies will be compatible with new technology or new industry standards.
See "Business--Competition."     
       
DEPENDENCE ON EFFECTIVE MANAGEMENT INFORMATION SYSTEMS
   
  As a telecommunications service provider, the Combined Company must record
and process millions of call detail records quickly and accurately to produce
customer bills and financial reports in a timely manner. The Combined Company
believes that the integration of its management information systems and
switching platforms is essential in order to provide least cost routing and
efficient billing. Although the Combined Company's billing systems and
switching platforms located at its network switching centers in Ft. Lauderdale
and Los Angeles, California are to be integrated following this offering, there
can be no assurance that such integration can be completed on a cost effective
and timely basis. If its current systems become obsolete or are damaged, the
Combined Company may be unable to upgrade or replace such systems with another
integrated system at commercially reasonable prices, or at all. Failure to
maintain integrated billing and management information systems could have a
material adverse effect on the Combined Company.     
   
  Demands on the Combined Company's information systems will increase
significantly if the Combined Company realizes anticipated growth and expands
its customer base. There can be no assurance that the Combined Company's
information systems will be adequate as the volume of customer traffic
increases or that the Combined Company will not suffer adverse consequences
should such systems fail to operate effectively. In addition, the Combined
Company has not previously reported financial results on a quarterly basis and
there can be no assurance that the Combined Company will not encounter material
delays or errors in billing of customers or in financial reporting. While the
Combined Company believes that its information systems are sufficient for its
current operations, it will be necessary to expand the capacities and
capabilities of its systems as the Combined Company grows. There can be no
assurance that the Combined Company will be able to do so, and     
 
                                       15
<PAGE>
 
   
the failure to implement enhancements or to make the necessary investments in
the Combined Company's information systems in a timely fashion could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business--Network and Operations."     
   
  The computer system that runs the Combined Company's switches and billing
operation has not yet been upgraded to be Year 2000 compliant. The Combined
Company is currently evaluating its computer systems to identify potential
problems relating to the Year 2000 date change. The Combined Company does not
expect the cost to modify its computer systems to address Year 2000 issues
will be material to the Combined Company's financial condition or results of
operations, and does not anticipate any material disruption in its operations
as a result of any Year 2000 issues. The Combined Company does not have any
information concerning the potential impact of Year 2000 issues on any of its
suppliers or customers. In the event that the Combined Company or any of the
Combined Company's significant suppliers or customers does not successfully
and timely address Year 2000 issues, the Combined Company's business or
operations could be adversely affected.     
          
RISK OF NETWORK FAILURE     
   
  The success of the Combined Company is largely dependent upon the efficient
and uninterrupted operation of its network infrastructure. While the Combined
Company has fully redundant network switching centers, the Combined Company's
systems and operations remain vulnerable to damage or interruption from fire,
earthquake or other natural disaster and from power loss, telecommunications
failure, break-ins and similar events. The Combined Company's switching
centers are located in Los Angeles, California and Ft. Lauderdale, Florida,
and the Combined Company has additional equipment located in Hong Kong, Mexico
City, Colorado Springs, Colorado and Seattle, Washington. Although the
Combined Company carries business interruption insurance, there can be no
assurance that such insurance will be sufficient to cover any losses suffered
by the Combined Company. In addition, despite the implementation of network
security measures by the Combined Company, its servers are vulnerable to
computer viruses, electronic break-ins and similar disruptions, any of which
could lead to loss of customer data. The occurrence of any of the foregoing
could have a material adverse effect on the Combined Company's business,
financial condition and results of operations.     
   
  In the first two quarters of 1997, GlobalTel experienced temporary technical
and operational difficulties associated with the relocation of its primary
switching platform from Las Vegas to Los Angeles. As the Combined Company
attempts to expand its network to accommodate traffic growth, there will be
increased stress on its network equipment and traffic management systems.
There can be no assurance that the Combined Company will not experience
failure of all or part of its network. The Combined Company's operations also
are dependent on its ability to successfully expand its network and integrate
new and emerging technologies and equipment into its network, which are likely
to increase the risk of system failure and cause unforeseen strains upon the
network. Significant or prolonged system failures could damage the reputation
of the Combined Company and result in the loss of customers, could hinder the
Combined Company's ability to obtain new customers and could have a material
adverse effect on the Combined Company's business, financial condition and
results of operations. See "Business--Network and Operations."     
 
DEPENDENCE UPON EXECUTIVE OFFICERS AND MANAGEMENT PERSONNEL
   
  The Combined Company's operations are dependent upon the continued services
of Ronald P. Erickson, its Chairman of the Board, Robert A. Spade, its Vice-
Chairman of the Board and Chief Executive Officer, and Patrick R. Scanlon, its
President and Chief Operating Officer. The loss of the services of any of
Messrs. Erickson, Spade or Scanlon could have a material adverse effect on the
Combined Company. The Combined Company has employment agreements with Messrs.
Spade and Scanlon that expire in 2000 and intends to enter into an employment
agreement with Mr. Erickson. The Combined Company maintains a key-person life
insurance policy on the life of Mr. Spade in the amount of $2 million, and has
applied for key-person life insurance on the life of Mr. Scanlon in the amount
of $2 million. The Combined Company's success also is dependent on its ability
to hire and retain other qualified management, technical, sales and customer
service personnel. There can be no     
 
                                      16
<PAGE>
 
   
assurance that the Combined Company will be successful in recruiting and
retaining such personnel. See "Management."     
          
PROPRIETARY RIGHTS     
   
  The Combined Company does not have a formal intellectual property protection
program. It relies on trade secrets and contractual restrictions to establish
and protect its technology. The Combined Company's success depends in part on
its ability to enforce intellectual property rights for its proprietary
technology, both in the United States and in other countries. The Combined
Company's proprietary technology is protected by the use of confidentiality
agreements that restrict the unauthorized distribution of the Combined
Company's proprietary data. While the Combined Company has attempted to limit
unauthorized use of its technology and the dissemination of its proprietary
information, there can be no assurance that the Combined Company will be able
to retain its proprietary technology and prohibit the unauthorized use of
proprietary information. The hardware and other equipment used by the Combined
Company for its call-reorigination systems are purchased from third party
suppliers and therefore are not proprietary to the Combined Company. See
"Business--Technology" and "--Intellectual Property."     
          
VALUE ADDED TAX AND SALES TAX COLLECTION     
   
  The Combined Company does not currently collect value-added tax ("VAT"),
sales tax or other similar taxes (other than federal excise tax) in respect of
any of its services. In addition, the rules for imposition of VAT vary from
country to country. For example, some EU member states deem telecommunications
services provided by U.S.-based companies to be performed outside the EU and,
therefore, exempt from VAT. Other EU member states, however, impose VAT on
telecommunications services provided by non-EU based companies. If the
Combined Company is required to collect VAT, sales or similar taxes on the
sale of its services, its business, financial condition and results of
operations could be materially adversely affected.     
       
       
RISKS RELATED TO THE OFFERING
   
OFFERING PRICE DETERMINATION; LIMITED PUBLIC MARKET; PRICE FLUCTUATIONS     
   
  The public offering price of the Common Stock has been determined by the
Combined Company and the Representatives of the Underwriters (the
"Representatives") and does not necessarily bear any relationship to the
assets, book value, or earnings history of the Combined Company or any other
investment criteria. Prior to this offering, there has been only a limited
public market for the Common Stock of CSI on the OTC Bulletin Board. Although
the Common Stock is expected to be approved for quotation on the Nasdaq
SmallCap Market upon notice of issuance, there can be no assurance that an
active trading market will develop. Factors such as quarterly fluctuations in
results of operations, the Combined Company's ability to meet analysts'
expectations, changes in financial estimates by securities analysts or market
conditions in general may cause the market price of the Common Stock to
fluctuate, perhaps substantially. In addition, in recent years the stock
market has experienced significant price and volume fluctuations. These
fluctuations, which are often unrelated to the operating performance of
specific companies, have had a substantial effect on the market price of the
stock of many small capitalization companies such as the Combined Company.
Factors such as those cited above, as well as other factors that may be
unrelated to the operating performance of the Combined Company and may be
beyond its control, could adversely affect the price of the Common Stock. See
"Underwriting."     
   
SHARES ELIGIBLE FOR FUTURE SALE; RIGHTS TO ACQUIRE SHARES     
   
  Following this offering,    shares of the Combined Company's outstanding
shares of Common Stock will be "restricted securities" and may in the future
be sold upon registration or in compliance with an exemption from registration
such as the exemption provided by Rule 144 adopted under the Securities Act.
Rule 144 as currently in effect generally provides that beneficial owners of
shares who have held such shares for one year may sell within a three-month
period a number of shares not exceeding the greater of 1% of the total
outstanding shares or the average trading volume of the shares during the four
calendar weeks preceding such sale. Of the     
 
                                      17
<PAGE>
 
   
   shares of restricted stock that are presently outstanding, approximately
shares of restricted stock will have satisfied the one year holding period
required by Rule 144. The remaining shares of restricted stock will become
available for resale pursuant to Rule 144 in various amounts each month, with
all shares of restricted stock being available for resale by      1999. All of
the officers and directors and persons known by CSI to be the beneficial
holders of 2% or greater of the Common Stock outstanding prior to this
offering have agreed with the Representatives not to sell such shares for a
period of 12 months following the date of this Prospectus. The Selling
Securityholders have agreed with the Representatives not to sell their shares
for a period of 180 days following the date of this Prospectus. See "Shares
Eligible For Future Sale."     
          
  At the date of this Prospectus, the Combined Company has reserved shares for
issuance upon the exercise or conversion of: (i) options to purchase up to
shares of Common Stock, which have a weighted average exercise price of $
per share, (ii) warrants to purchase up to    shares of Common Stock, which
have a weighted average exercise price of $   per share, (iii) convertible
promissory notes in the aggregate principal amount of $30,000 convertible into
an undeterminable number of shares of Common Stock, which have a conversion
price per share equal to 90% of the average bid and asked price of the Common
Stock on the day before conversion, (iv)    shares of GlobalTel's Series A
Convertible Preferred Stock, which will be converted into approximately
shares of Common Stock and unpaid dividends on the Series A Convertible
Preferred Stock, which will be converted into Common Stock at a price of $
per share, (v) convertible promissory notes in the aggregate principal amount
of approximately $2.7 million that were issued by GlobalTel, which have a
conversion price per share equal to the price of the Common Stock in this
offering, and (vi) GlobalTel Full Coverage Notes in the aggregate principal
amount of approximately $3.0 million which have a conversion price of $   per
share. At the completion of this offering, the Representatives will receive
warrants (the "Representatives' Warrants") to purchase up to    shares of
Common Stock at an exercise price of $   (120% of the offering price of the
Common Stock) during a period of four years commencing one year following the
date of this Prospectus. During the terms of the outstanding options and the
Representatives' Warrants, the holders thereof are given the opportunity to
profit from a rise in the market price of the Common Stock, and the exercise
thereof may dilute the ownership interests of existing shareholders, including
investors in this offering. The existence of warrants, options and the
Representatives' Warrants may adversely affect the terms on which the Combined
Company may obtain additional equity financing in the future. Moreover, the
holders are likely to exercise their rights to acquire Common Stock at a time
when the Combined Company would otherwise be able to obtain capital on terms
more favorable than through the exercise of such options and warrants. See
"Management--Stock Option Plan" and "Underwriting."     
   
BENEFITS TO RELATED PARTIES; RELATED PARTY TRANSACTIONS     
   
  The Combined Company will use a portion of the net proceeds of the offering
to repay the Bridge Notes, as to which Robert A. Spade and Patrick R. Scanlon
have provided personal guaranties and pledged a portion of their Common Stock.
Such guaranties and pledges will be released upon completion of this offering.
A number of the officers and directors of GlobalTel who will become executive
officers and directors of the Combined Company hold notes and warrants to
purchase common stock of GlobalTel. Messrs. Ronald P. Erickson, Bruce L.
Crockett and Lyman C. Hamilton, members of the Board of Directors of the
Combined Company, are also directors of IBNET, and each holds options to
purchase   shares of IBNET's common stock. In addition, Mr. Hamilton owns
100,000 shares of IBNET's common stock. IBNET previously entered into a ten-
year marketing agreement with GlobalTel. See "Management" and "Certain
Transactions."     
   
ANTI-TAKEOVER EFFECTS OF CERTAIN CHARTER AND STATUTORY PROVISIONS     
   
  The Combined Company's Articles of Incorporation authorizes the issuance of
up to 5,000,000 shares of Preferred Stock. The Preferred Stock may be issued
in series with the material terms of any series determined solely by the Board
of Directors. Such terms would likely include dividend rights, conversion
features, voting rights, redemption rights and liquidation preferences. The
Combined Company does not currently anticipate that it will issue any
Preferred Stock. However, if the Combined Company does issue any series of
Preferred Stock in the future, it is likely that such shares will have
dividend privileges and liquidation preferences superior to those of the
Common Stock. Further, the Preferred Stock may be issued with voting,
conversion or other terms     
 
                                      18
<PAGE>
 
   
determined by the Board of Directors including, among others, dividend payment
requirements, redemption provisions, preferences as to dividends and
distributions, and preferential voting rights. In addition, certain provisions
of Colorado law could have the effect of delaying, deterring or preventing a
change in control of the Combined Company.     
   
ABSENCE OF DIVIDENDS     
   
  The Combined Company does not anticipate paying any cash dividends on its
Common Stock in the foreseeable future. The Combined Company intends to retain
profits, if any, to fund growth and expansion. See "Dividend Policy."     
   
DILUTION     
   
  This offering will result in immediate substantial dilution of $   ( %) per
share, which amount represents the difference between the pro forma net
tangible book value per share after the offering and an assumed public
offering price of $   per share. See "Dilution."     
   
LIMITATION OF LIABILITY     
   
  The Combined Company's Articles of Incorporation provides that directors of
the Combined Company shall not be personally liable for monetary damages to
the Combined Company or its shareholders for a breach of fiduciary duty in
their capacities as directors, subject to limited exceptions. Although such
limitation of liability does not affect the availability of equitable remedies
such as injunctive relief or rescission, the presence of these provisions in
the Articles of Incorporation could prevent the recovery of monetary damages
against directors of the Combined Company. See "Management--Limitation of
Liability and Indemnification."     
   
LISTING AND MAINTENANCE CRITERIA FOR NASDAQ SECURITIES     
   
  The Combined Company has applied for listing on the Nasdaq SmallCap Market
and believes it will meet the recently adopted standards for such listing
which require: (i) net tangible assets of $4 million, (ii) a public float of
one million shares, (iii) a market value of the public float of $5 million,
(iv) three market makers, (v) a minimum $4.00 bid price per share of common
stock, and (vi) at least 300 shareholders.     
   
  Nasdaq has also adopted new criteria for continued Nasdaq SmallCap Market
eligibility. In order to continue to be included on the Nasdaq SmallCap Market
(thereby exempting a company from the "penny stock" regulations described
below), a company must maintain (i) at least two market makers, (ii) 300
holders of its common stock, (iii) a minimum bid price of $1.00 per share of
common stock, (iv) net tangible assets of $2 million (unless the company had
net income of $500,000 in two of the last three years or a market
capitalization of $35 million), (v) 500,000 shares in the public float, and
(vi) a market value of the public float of $1 million. The Combined Company's
failure to meet these maintenance criteria in the future may result in the
termination of listing of the Common Stock on the Nasdaq SmallCap Market. In
such event, trading, if any, in the Common Stock may continue to be conducted
in the non-Nasdaq over-the-counter market in what are commonly referred to as
OTC Bulletin Board and the "pink sheets." As a result, an investor may find it
more difficult to dispose of or to obtain accurate quotations as to the market
value of the Common Stock.     
   
DISCLOSURE RELATED TO PENNY STOCKS     
   
  The Commission has adopted rules that define a "penny stock" as equity
securities priced at under $5.00 per share which are not listed for trading on
Nasdaq (unless (i) the issuer has a net worth of $2 million if in business for
more than three years or $5 million if in business for less than three years,
or (ii) the issuer has had average annual revenue of $6 million or more for
the prior three years). The Combined Company's Common Stock will not be
considered a "penny stock" initially if listed on the Nasdaq SmallCap Market.
In the event that the Common Stock is characterized in the future as penny
stock, broker-dealers dealing in the Common Stock will be subject to the
disclosure rules for transactions involving penny stocks which require the
broker-dealer, among other things, to (i) determine the suitability of
purchasers of the Common Stock, and obtain the     
 
                                      19
<PAGE>
 
   
written consent of purchasers to purchase such Common Stock prior to the
transaction, (ii) provide customers with required risk disclosure documents,
disclose quotation and compensation information and provide monthly price
information and other required information, and (iii) disclose the best
(inside) bid and offer prices for such Common Stock and the price at which the
broker-dealer last purchased or sold the Common Stock. The additional burdens
imposed upon broker-dealers may discourage them from effecting transactions in
penny stocks, which usually reduces the liquidity of such securities.     
   
RISKS RELATING TO FORWARD-LOOKING STATEMENTS     
   
  This Prospectus contains certain forward-looking statements within the
meaning of Section 27A of the Securities Act and Section 21E of the Exchange
Act. Such forward-looking statements include, but are not limited to,
statements regarding the Combined Company's marketing plans, expectations
concerning growth in the market, and the planned use of proceeds. Actual
results could differ from those projected in any forward-looking statement.
The forward-looking statements are made as of the date of this Prospectus and
the Combined Company assumes no obligation to update such forward-looking
statements, or to update the reasons why actual results may differ from those
projected in the forward-looking statements. Numerous factors, including
without limitation those factors mentioned in this "Risk Factors" section,
could cause future results to differ substantially from those contemplated in
such forward-looking statements. A number of the factors that may influence
future results of operations are outside the Combined Company's control. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

<PAGE>
 
                               THE ACQUISITIONS
   
  Following completion of the offering, CSI will complete the GlobalTel Merger
and the ITC Acquisition.     
   
  GlobalTel provides international telecommunications services, principally to
small- and medium-sized business customers, in emerging telecommunications
markets. Currently, GlobalTel offers international long-distance, calling
cards and enhanced voice services to more than 8,500 customers in over 120
countries. GlobalTel began operations in 1995 with its entry into the
international call-reorigination business. GlobalTel primarily markets its
telecommunications services through a network of over 81 independent sales
agents that currently cover more than 80 countries. GlobalTel also has several
strategic relationships, including an exclusive marketing agreement with
IBNET, the managing member of the Consortium of Global Commerce, which will
enable the Combined Company to market its services through several thousand
individual chambers of commerce located in over 200 countries. In addition,
Novell will provide the Combined Company with a distribution channel for its
services through a select number of Novell's 25,000 value-added resellers
("VARs"). GlobalTel's telecommunications network includes an international
network switching center in Los Angeles, California consisting of two Summa
Four telecommunications switches and the use of a Northern Telecom DMS 250
tandem switch.     
   
  ITC provides call-reorigination services, primarily targeting individuals
and small business customers in Europe, Africa and the Middle East. Currently,
ITC offers international long-distance, calling cards and enhanced voice
services to more than 8,500 customers. ITC markets its call-reorigination
services through a network of approximately 55 independent sales agents. ITC
services its customers through a switching platform located at its
telecommunications center in Ft. Lauderdale, Florida. The center is a fiber
optic facility consisting of two NACT 1000 port class 3 switches that direct
international telephone and facsimile traffic and also have a broad spectrum
of Internet capabilities. ITC's facility includes an integrated management
information system and switching platform, which enhances ITC's ability to
provide least cost routing and efficient billing services.     
   
Benefit of Acquisitions     
   
  CSI believes that the GlobalTel Merger and the ITC Acquisition will provide
a number of advantages to the Combined Company. These advantages include:     
   
  Increased Buying Power with Carriers. The Combined Company will continue to
purchase minutes from substantial international telecommunications carriers
such as AT&T, Sprint, Cable & Wireless and Teleglobe. Upon completion of the
GlobalTel Merger and the ITC Acquisition, the Combined Company will use its
much larger combined call volume to seek lower rates from its carriers. In
addition, the carriers' minimum volume commitments will be easier for the
Combined Company to fulfill and redundant carrier deposits may be eliminated.
See "Business--Industry and Market Opportunity" and "--Network and
Operations."     
   
  Combined Cost Structures. Although there can be no assurance, management
believes the integration of existing cost structures will result in immediate
savings for the Combined Company. CSI has traditionally concentrated its
marketing efforts on South America, GlobalTel has focused on the Pacific Rim,
while ITC has focused on Africa and Europe. Through relationships with its
carriers, each company believes it has achieved superior rate structures in
its geographic region. The Combined Company anticipates integrating the best
of all three rate structures to realize cost reductions.     
          
  Operating Efficiencies and Geographic Diversification. As the Combined
Company attains greater geographic diversity, management believes it will
realize efficiencies by having traffic spread more evenly over the 24-hour
day. Equipment and personnel can be allocated and optimized more efficiently
over 24 hours, rather than over the shorter "peak" periods associated with
each continent. Geographic diversity also reduces the concentration of the
Combined Company's exposure to regulatory and business risk and reduces its
dependence upon individual independent sales agents.

  Cross-Marketing Additional Services. In addition to the telecommunications
services each company presently provides, GlobalTel's and ITC's switches make
it possible for the Combined Company to significantly expand its carrier and
reseller business, and to introduce new enhanced services such as enhanced fax
and business grade Internet services to its existing customers. In addition,
the Combined Company's DIAL and LINK-US technologies facilitate transparent
call-reorigination, under which the mechanics of the call-reorigination
process are invisible to the customer.     
   
  Elimination of Redundant Overhead. The Combined Company believes it will be
able to reduce its number of employees and its outside contractors through the
consolidation of functional areas such as accounting, customer service and
technical operations. The Combined Company intends that marketing, accounting
and administration functions will be centralized in Colorado Springs,
Colorado, while technical and customer service functions will be concentrated
in Fort Lauderdale, Florida. Some additional technical and administrative
functions will continue to be performed in Los Angeles, California and
Seattle, Washington.     
   
  Capitalizing on Personnel Experience and Expertise. CSI, GlobalTel and ITC
each possess broad telecommunications industry experience. The Combined
Company anticipates that synergies will be achieved in the areas of marketing,
collections, customer provisioning, carrier relationships, Internet expertise,
and development and enhancement of switch technologies. Pursuant to the
Reciprocal Telecommunications Agreement between CSI and ITC, those companies
have already integrated certain of their key operations and personnel.     
   
 Terms of the Acquisitions     
   
  In April 1998, CSI entered into an agreement in principle to merge with
GlobalTel. Following the GlobalTel Merger, the Combined Company will be
renamed "CS GlobalTel, Inc." The agreement provides for the exchange of all of
the outstanding shares of common stock of GlobalTel for shares of Common Stock
of CSI. The holders of GlobalTel common stock will receive    shares of Common
Stock of CSI for each share of GlobalTel common stock. Upon completion of the
GlobalTel Merger, Ronald P. Erickson, the current Chief Executive Officer of
GlobalTel, will become Chairman of the Board of the Combined Company. The
GlobalTel Merger is conditioned on, among other things, the approval of the
shareholders of both CSI and GlobalTel and there being no material adverse
change in the condition of either company. CSI expects the GlobalTel Merger
will be completed shortly after this offering.     
   
  CSI has entered into an agreement to acquire all of the outstanding capital
stock of ITC for $3.3 million in cash and     shares of Common Stock based on
an assumed initial offering price of $    per share, to be issued on the first
anniversary of the closing of this offering. A portion of the cash will be
held in escrow for one year to secure certain indemnification obligations of
the shareholders of ITC. ITC is currently owned by Lynch Family, LLC, Philip
A. Thomas and Sean Thomas. Upon completion of the ITC Acquisition, Philip A.
Thomas will become Vice President--General Manager and Sean Thomas will become
Director of Business Development for Europe of the Combined Company. The ITC
Acquisition is conditioned upon, among other things, there being no material
adverse change in the condition of either company. The ITC Acquisition is
expected to occur concurrent with the consummation of this offering.     
   
Prior Acquisition     
   
  In September 1995, in an effort to increase the number of shareholders of
CSI's Common Stock, and become a publicly traded entity, CSI's shareholders
approved a plan of merger to acquire all of the outstanding shares of Redden
Dynamics Corporation ("Redden") for $34,500 cash and     shares of CSI's
Common Stock. Under the plan of merger, the shareholders of Redden received
one share of the CSI's Common Stock in exchange for each     shares of Redden
stock. Effective as of the date of the merger, all shares of Redden were
canceled, the assets of Redden became assets of CSI and Redden ceased to
exist. Redden's only recorded asset consisted of $11,050 of organizational
costs. Redden had no liabilities and had no revenue or expenses from its
inception. Subsequent to the merger, CSI determined that Redden's assets were
of no value to CSI. Accordingly, no amounts have been recognized for the
issuance of the Common Stock in connection with the merger of Redden. See
"Certain Transactions."

                             USE OF PROCEEDS     
   
  Based on an assumed offering price of $      per share, the net proceeds
from the sale of the shares of Common Stock offered hereby are estimated to be
approximately $   million ($     million if the Underwriters' over-allotment
option is fully exercised).     
   
  The Combined Company plans to use (i) approximately $3.1 million to repay
the outstanding amount of Bridge Notes issued in December 1997 and estimated
accrued interest thereon; (ii) approximately $3.0 million to repay the
GlobalTel Full Coverage Notes issued by GlobalTel in December 1997; (iii)
approximately $3.0 million to pay deferred payables owed by the Combined
Company; (iv) approximately $2.9 million to complete the ITC Acquisition; (v)
approximately $1.6 million to pay the outstanding amount of the GlobalTel
Bridge Notes, issued at various times during 1996 and 1997; (vi) approximately
$1.1 million to repay the outstanding amount of the GlobalTel Note that
becomes payable in June 1998; (vii) approximately $600,000 to repay various
outstanding short term debt of CSI; (viii) approximately $400,000 to install
automated switching equipment that facilitates transparent call-reorigination
services in high volume customers; (ix) approximately $400,000 to purchase or
lease and install regional switches or other telecommunications equipment in
select countries to facilitate least cost routing; (x) approximately $200,000
for technical development associated with the Combined Company's enhanced
services; and (xi) the remaining net proceeds for working capital and general
corporate purposes, which includes an $80,000 severance payment to a former
employee of CSI and $50,000 to be paid a director of CSI for consulting
services provided. Additionally, a portion of the proceeds will be used to
fund the repurchase of any securities of the Combined Company tendered in
connection with the Rescission Offer in an approximate amount of up to $2.8
million, plus approximately $397,000 of statutory interest (as of June 30,
1998), of which up to approximately $1.4 million may be paid to officers and
directors of the Combined Company and their affiliates if they accept the
Rescission Offer. See "Rescission Offer."     
   
  The Bridge Notes bear interest at a rate of 10% per annum and are repayable
on the earlier of five days after the consummation of this offering or
December 30, 1998. CSI used the proceeds of the December 1997 Financing
principally to repay trade payables and notes to telecommunications carriers.
The notes issued by GlobalTel bear interest at a rate of either 10% or 12% and
are due upon the completion of this offering. The proceeds of such note
issuances were used for working capital or to repay debt.     
   
  The foregoing represents the Combined Company's best estimate of the use of
the net proceeds to be received in this offering, based on current planning
and business conditions. However, the Combined Company reserves the right to
change such uses when and if market conditions or unexpected changes in
operating conditions or results of operations occur. The amounts actually
expended for each use may vary significantly depending upon a number of
factors including, but not limited to, future growth and the amount of cash
generated by the Combined Company's operations. The Combined Company believes
that its existing capital resources, together with the net proceeds of this
offering, will be sufficient to maintain the current and planned operations of
the Combined Company for a period of at least 12 months from the date of this
Prospectus. Net proceeds not immediately required for the purposes described
above will be invested principally in U.S. government securities, short-term
certificates of deposit, money market funds or other short-term, interest-
bearing securities.     
       
                                DIVIDEND POLICY
   
  CSI has never declared or paid any cash dividends or distributions on its
capital stock. The Combined Company anticipates that for the foreseeable
future all earnings will be retained for use in the Combined Company's
business and no cash dividends will be paid to shareholders. Any payment of
cash dividends in the future on the Common Stock will be dependent upon the
Combined Company's financial condition, results of operations, current and
anticipated cash requirements, plans for expansion, restrictions, if any,
under debt obligations, as well as other factors that the Board of Directors
deems relevant.

  On       , 1998, the closing bid price of the Common Stock as reported on
the OTC Bulletin Board was $   per share. CSI had approximately    holders of
record of Common Stock as of March 31, 1998. While CSI is aware that a number
of beneficial owners of its Common Stock hold shares in street name, no
estimate has been made as to the number of shareholders owning stock of CSI in
street name.

                                 DILUTION     
   
  As of December 31, 1997, CSI's net tangible book value was a $    million
deficit or $    per share of Common Stock. After giving effect to the sale by
the Combined Company of     shares of Common Stock at an assumed offering
price of $   per share and the receipt of the estimated net proceeds thereof,
the GlobalTel Merger and the ITC Acquisition, the pro forma net tangible book
value of the Combined Company as of December 31, 1997 would have been
approximately $    million or $     per share. This represents an immediate
increase in pro forma net tangible book value of $     per share to existing
shareholders and an immediate dilution of $    per share to new investors.
"Dilution" is determined by subtracting pro forma net tangible book value per
share after the offering from the assumed offering price per share of Common
Stock, as illustrated by the following table:

                            SELECTED FINANCIAL DATA
                (IN THOUSANDS, EXCEPT PER SHARE AND SHARE DATA)
   
  The following selected financial data should be read in conjunction with the
financial statements of CSI, GlobalTel and ITC and the related notes thereto
and "Management's Discussion and Analysis of Financial Condition and Results
of Operations." The selected financial data below has been derived from CSI's
audited financial statements as of April 30 1996 and 1997 and for each of the
three years in the period ended April 30, 1997, from GlobalTel's audited
consolidated financial statements as of December 31, 1996 and 1997 and for
each of the three years in the period ended December 31, 1997, from ITC's
audited statement of operations data for the ten months ended October 31, 1997
and the years ended December 31, 1995 and 1996, and the balance sheet data as
of December 31, 1996, and October 31, 1997. The selected financial data for
CSI with respect to the periods ended January 31, 1997 and 1998 and the
balance sheet data as of January 31, 1998 have been derived from CSI's
unaudited financial statements. The selected financial data for ITC with
respect to the periods ended December 31, 1996 and January 31, 1998 and the
balance sheet data as of January 31, 1998 have been derived from ITC's
unaudited financial statements. Management believes that CSI's and ITC's
interim financial statements as of January 31, 1998 and for the periods ended
December 31, 1996, January 31, 1997 and 1998 include all adjustments,
consisting of normal recurring accruals, necessary for a fair presentation of
the financial position and the results of operations of CSI and ITC for such
interim periods. Prior results are not a prediction of future results of
operations. The Pro Forma As Adjusted information does not purport to present
the Combined Company's financial position or results of operations that would
have occurred had the transactions, to which pro forma effect is given, been
consummated as of the dates or for the periods indicated and do not purport to
project the Combined Company's financial position or results of operations at
any future date or for a future period, and should be read in conjunction with
the separate financial statements of CSI, GlobalTel and ITC and the pro forma
condensed combined financial statements of CSI, GlobalTel and ITC.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
          
  With the exception of historical matters, the matters discussed herein are
forward-looking statements that involve risks and uncertainties. Forward-
looking statements include, but are not limited to, statements concerning
anticipated trends in revenue and net income, the mix of the Combined
Company's revenue, projections concerning operations and available cash flow.
The Combined Company's actual results could differ materially from the results
discussed in such forward-looking statements. Factors that could cause or
contribute to such differences include those discussed below, as well as those
discussed in "Risk Factors" and elsewhere in this Prospectus.     
 
                             THE COMBINED COMPANY
   
OVERVIEW     
   
  The Combined Company is a growing provider of international
telecommunications services offering long distance, calling cards and enhanced
voice and data services. With more than 25,500 customers in over 170
countries, the Combined Company primarily serves markets that historically
have been underserved by large telecommunications providers and ITOs. The
Combined Company provides its telecommunications services through its (i)
voice switching and global fax messaging infrastructure in Los Angeles,
California, (ii) voice switching and billing center in Ft. Lauderdale,
Florida, (iii) access to third party infrastructure through international
telecommunications carriers and through Equant, a global data network services
provider, and (iv) enhanced fax nodes in Hong Kong and Mexico City.     
   
  The Combined Company currently focuses on international call-reorigination,
capitalizing on the arbitrage opportunity created by differences between U.S.
and international long-distance rates. The Combined Company also resells its
international long-distance services to other telecommunications carriers and
resellers on a wholesale basis. In addition, the Combined Company provides
prepaid calling cards and enhanced voice services, consisting of voice-mail
and conference calling. For the 12 months ended December 31, 1997,
approximately 88.0% of the Combined Company's revenue was derived from call-
reorigination and 12.0% was provided by carrier resales. Going forward, the
Combined Company intends to leverage the expertise derived from, and
capitalize on the established customer base generated by, its call-
reorigination business to provide higher margin telecommunications services
such as call-through, enhanced fax and business grade Internet services.     
   
  The Combined Company generally realizes higher gross margins from its call-
reorigination services than from sales to carriers and resellers. Sales to
carriers and resellers, however, provide a source of additional revenue and
add significant minutes originating on the Combined Company's network, which
improves the Combined Company's purchasing power with its carriers and enables
it to take advantage of volume discounts. Unlike call-reorigination, minutes
generated from sales to carriers and resellers generally are "billable"
minutes even if the destination segment of the call is not answered or
connected. Furthermore, the Combined Company is not responsible for billing
end users or paying independent sales agent commissions. Therefore, operating
costs generally are lower for sales to carriers and resellers.     
   
  The Combined Company seeks to minimize costs through negotiation of
favorable rates with its existing long distance carriers. Under certain
carrier contracts, the Combined Company obtains guaranteed rates, which
generally are more favorable than otherwise would be available, by committing
to purchase a minimum number of minutes from such carriers. If the Combined
Company fails to meet its minimum requirements under a carrier contract, it
could still be required to pay its minimum monthly commitment as a penalty.
The Combined Company is seeking to enter into agreements with additional long
distance carriers in order to apply "least cost routing" techniques, which
enable the Combined Company to access the lowest transmission costs charged by
its carriers for each call segment. The Combined Company also intends to
establish additional switching facilities outside the U.S. in order to utilize
a larger number of long distance carriers and reduce its per minute
transmission costs. See "Use of Proceeds" and "Business--Business Strategy."

   As part of its acquisition strategy, CSI has entered into an agreement in
principle to merge with GlobalTel and an agreement to acquire ITC. The
GlobalTel Merger and the ITC Acquisition will enable the Combined Company to
rapidly obtain access to complementary infrastructure, personnel, customer
bases, sales and marketing resources and strategic relationships. The
integration of GlobalTel and ITC with CSI will afford the Combined Company an
opportunity to increase revenue through cross-marketing its services to each
company's customer base and the sale of excess international capacity to other
carriers and resellers. The Combined Company will seek to improve its margins
through the administrative efficiencies and operating synergies created by the
combination of the companies and through improved rate structures with
carriers.     
          
  The Combined Company's fiscal year end will be December 31.     
       
          
ACCOUNTING POLICIES AND PROCEDURES     
   
  Revenue is generated primarily from international call-reorigination
services and is based on the minutes of customer use billed by the Combined
Company on completed calls. The Combined Company's call-reorigination revenue
represents the majority of the Combined Company's revenue and has increased as
the Combined Company has added independent sales agents and introduced its
services into new countries. The Combined Company also sells international
long distance minutes to other telecommunications carriers and resellers on a
wholesale basis. The Combined Company's call re-origination customer base is
diversified both geographically and by customer type.     
   
  Approximately 60.0% of all revenue is collected through automatic charges to
pre-approved customer credit cards. Under the terms of their agreements, the
independent sales agents are responsible for collecting customer payments
except for credit card payments, and independent sales agents generally are
responsible for customer bad debts less, in some cases, an allowance granted
by the Combined Company. Failure of independent sales agents to collect and
remit customer payments to the Combined Company presents a risk to the
Combined Company. Although collection terms for cash customers are net 30
days, the time necessary to process and collect billings through the Combined
Company's independent sales agents may at times result in receivables reaching
60 to 90 days.     
   
  Cost of revenue consists primarily of costs paid to carriers for the
origination and transmission of voice and data telecommunications services and
to a lesser extent, debit card costs and allowances and discounts. Currently,
a substantial portion of the Combined Company's telecommunications revenue is
derived from services that are accessed through the facilities of long
distance carriers. Accordingly, a significant portion of the Combined
Company's cost of telecommunications services is variable, based on the number
of minutes of use, with transmission costs being the Combined Company's most
significant expense. In December 1997, the Combined Company's aggregate
minimum monthly commitments were approximately $550,000, which represented
approximately 23.5% of the Combined Company's monthly variable transmission
cost.     
          
  Sales and marketing expense primarily represents commissions paid to
independent sales agents, compensation paid to in-house salespersons and
advertising expense. To date, the Combined Company's decision to use
independent sales agents has been primarily driven by the low initial fixed
costs associated with this distribution channel, and the benefits of
independent sales agents' familiarity with local business and marketing
practices. See "Risk Factors--Dependence on Key Sales Agents" and "Business--
Sales and Marketing."     
   
  General and administrative expense primarily represents compensation for
customer service, executive and accounting personnel, costs associated with
the operation and maintenance of the Combined Company's network switching
centers, costs related to the technical development of, and market planning
for, the Combined Company's planned enhanced services, professional fees, bad
debt expense and other operating and corporate overhead costs. The Combined
Company has a policy of aggressively attempting to collect receivables from
independent sales agents and customers who fail to remit payment in a timely
manner. While the Combined Company seeks to minimize bad debt, the Combined
Company's experience indicates that a certain portion of past due receivables
will never be collected.     
 
                                      29

  Depreciation expense includes depreciation of switching and network
equipment, furniture and fixtures. The Combined Company provides for
depreciation using the straight line method of depreciation over the estimated
useful lives of the assets, which range from five to ten years. The Combined
Company will incur amortization expense which relates to the amortization of
the intangible assets recorded in the GlobalTel Merger and the ITC
Acquisition. The intangible assets will include identifiable intangible assets
which will be amortized over a two to seven year period and that relate to
distribution and customer arrangements, intellectual property and licenses.
Identifiable intangible assets also include in-process research and
development which will be charged to operating expense upon completion of the
GlobalTel Merger. In addition, intangible assets include goodwill, which will
be amortized over a five-year period.     
          
  Interest and debt discount expense includes interest expense on indebtedness
and non-cash financing expenses including amortized debt discount and
amortized deferred offering costs associated with debt financing.     
   
  As used herein, "EBITDA' is defined as net income or loss plus depreciation,
amortization and interest expense, income taxes and other non-cash charges,
minus extraordinary income and gains and non-cash income, if any, and plus
extraordinary losses, if any. EBITDA is not a measure of financial performance
under generally accepted accounting principles and should not be considered a
substitute for measures of performance prepared in accordance with generally
accepted accounting principles.     
       
          
COMPARISON OF 12 MONTHS ENDED DECEMBER 31, 1995, 1996 AND 1997     
   
  The Combined Company's historical combined revenue was $15.1 million, $27.1
million and $35.3 million for the 12 months ended December 31, 1995, 1996 and
1997, respectively. The increase in revenue resulted from increased usage by
existing customers, the addition of new customers as the Combined Company
expanded its independent sales agent network and commenced providing services
in new countries, and the commencement of sales to carriers and resellers.
Call-reorigination revenue represented 100.0%, 95.8% and 88.0% for 1995, 1996
and 1997, respectively, while carrier and reseller revenue represented 4.2%
and 12.0% for 1996 and 1997, respectively. The Combined Company anticipates
that revenue will increase as it begins to cross-market its services to its
customers and continues to focus on carrier sales.     
   
  The Combined Company's historical combined cost of revenue was $11.2
million, $20.8 million and $28.1 million for the 12 months ended December 31,
1995, 1996 and 1997, respectively. As a percent of revenue, these costs were
74.3%, 76.8% and 79.7% for 1995, 1996 and 1997, respectively. The Combined
Company anticipates a significant increase in transmission costs associated
with greater calling volume. The growth in transmission volume should improve
the Combined Company's ability to negotiate preferential rates with its
carriers. In addition, integrating the cost structures of the Combined Company
may result in reduced costs per minute of use. The Combined Company expects
gross margin percentages may decline if carrier and reseller revenue increases
as a percentage of revenue or if price reductions occur due to competition.
       
  The Combined Company's historical combined sales and marketing expense was
$2.6 million, $3.7 million and $3.5 million for the 12 months ended December
31, 1995, 1996 and 1997, respectively. As a percent of revenue, these costs
were 17.5%, 13.6% and 10.0% for 1995, 1996 and 1997, respectively. The
Combined Company anticipates a significant increase in sales and marketing
expense in absolute dollars due to an increase in independent sales agent
commissions caused by an expected increase in revenue. However, these costs as
a percentage of revenue are expected to decrease as the fixed portion of sales
and marketing expense, such as costs associated with in-house sales personnel
and advertising, are spread across a broader revenue base. In addition, the
Combined Company expects sales and marketing expense to decrease as a
percentage of revenue if carrier and reseller revenue increase as a percent of
total revenue because sales to carriers and resellers do not have advertising
and sales commission costs.     
   
  The Combined Company's historical combined general and administrative
expense was $3.6 million, $9.3 million and $11.8 million for the 12 months
ended December 31, 1995, 1996 and 1997, respectively. General and
administrative expense in 1997 included non-recurring costs totaling $670,000
associated with GlobalTel's     
 
                                      30
<PAGE>
 
   
terminated public offering and $447,000 of non-cash compensation cost. As a
percent of revenue, general and administrative expense was 24.0%, 34.4% and
33.4% for 1995, 1996 and 1997, respectively. The Combined Company expects
general and administrative expense will decrease as a percent of revenue due
to cost savings resulting from operating efficiencies and the elimination of
redundant overhead.     
   
  The Combined Company's historical combined depreciation and amortization
expense was $203,000, $251,000 and $480,000 for the 12 months ended December
31, 1995, 1996 and 1997, respectively. As a percent of revenue, these costs
were 1.4%, .9% and 1.4% for 1995, 1996 and 1997, respectively. The Combined
Company anticipates amortization expense will increase by $11.5 million
annually due to amortization of the intangible assets related to the GlobalTel
Merger, the ITC Acquisition and future acquisitions not yet identified. In
addition, the Combined Company expects that depreciation expense may increase
due to planned capital expenditures related to the purchase and installation
of regional switches and automated switching equipment for its high volume
customers.     
   
  The Combined Company's historical combined interest and debt discount
expense was $50,000, $341,000 and $1.6 million for the 12 months ended
December 31, 1995, 1996 and 1997, respectively. As a percent of revenue, these
costs were .3%, 1.3% and 4.5% for 1995, 1996 and 1997, respectively. The
Combined Company anticipates non-cash financing expense of $1.4 million will
be incurred until completion of this offering due to the amortization of debt
discount expense, amortization of deferred offering costs and accrued interest
expense related to CSI's December 1997 Financing and the GlobalTel Full
Coverage Notes. The Combined Company expects interest expense may increase as
the Combined Company seeks other financing arrangements, such as a working
capital line of credit, lease financing, acquisition financing and term debt
to be used to fund the Combined Company's growth.     
   
  The Combined Company's historical combined negative EBITDA was $2.4 million,
$6.7 million and $8.0 million for the 12 months ended December 31, 1995, 1996
and 1997, respectively. As a percentage of revenue, negative EBITDA was 15.8%,
24.7% and 22.6% for 1995, 1996 and 1997, respectively.     
   
LIQUIDITY AND CAPITAL RESOURCES     
   
  The Combined Company's capital resources have been used to fund operating
losses, debt service and capital expenditures associated with development of
its customer base and the establishment and upgrade of its network
infrastructure. The Combined Company had a working capital deficit of $8.8
million at December 31, 1997. The Combined Company has historically satisfied
its capital requirements principally through a combination of sales of equity
and debt securities, borrowings from third parties and trade credit extended
by carriers.     
   
  The Combined Company believes that cash on hand, together with cash flow
from its operating activities and cash available from this offering, will be
sufficient to fund the Combined Company's existing operations at least for the
next 12 months. However, the Combined Company intends to continue its strategy
of rapid growth, primarily through the expansion of its infrastructure and
pursuing other growth opportunities such as acquisitions of complementary
international customer bases, products and infrastructure. The Combined
Company is currently reviewing various alternatives for obtaining additional
financing to fund this strategy. The proceeds from such financing are
anticipated to be used to expand the Combined Company's operations, fund the
Combined Company's growth and enable the Combined Company to undertake
additional strategic initiatives. There can be no assurance that the Combined
Company will be able to raise additional capital on acceptable terms or at
all. If the Combined Company is unable to obtain such additional capital, the
Combined Company may have to curtail its expansion of operations, growth and
other strategic initiatives, which could adversely affect the Combined
Company's business, financial condition and results of operations and its
ability to compete.     
 
EFFECTS OF INFLATION AND FOREIGN CURRENCY EXCHANGE
   
  Although increases in salaries, carrier costs and operating overhead can
adversely affect the Combined Company's operations, the Combined Company does
not believe that inflation has had a material effect on its operating results.
However, because future increases in inflation may cause the Combined
Company's suppliers     
 
                                      31
<PAGE>
 
   
to increase prices of materials and services to the Combined Company, an
increase in inflation could increase the Combined Company's cost of revenue
and operating expenses. Although the Combined Company's sales to date have
been denominated in U.S. dollars, the value of the U.S. dollar in relation to
foreign currencies also may adversely affect the Combined Company's revenue.
To the extent the Combined Company changes its pricing practices to denominate
prices in foreign currencies, the Combined Company will be exposed to
increased risks of currency fluctuation. Any such fluctuation could have a
material adverse effect on the Combined Company's earnings or assets when
translated into U.S. dollars. Although the Combined Company has not entered
into foreign exchange contracts to hedge exchange transactions, it may do so
in the future.     
 
SEASONALITY
 
  The Combined Company's business exhibits a small degree of seasonality.
Historically, the Combined Company's revenue (as well as sales in the
telecommunications industry in general) has decreased slightly in August and
December, which CSI attributes to vacations and holidays in its European and
Latin American markets and in the United States. As a result of these factors,
reported quarterly revenue in future periods will vary and are not indicative
of revenue in subsequent comparable periods.
 
ACCOUNTING PRONOUNCEMENTS
   
  In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 131, "Disclosure about
Segments of an Enterprise and Related Information" ("Statement 131"), which is
effective for financial statements with fiscal years beginning after December
15, 1997. Statement 131 requires that public business enterprises report
certain information about operating segments in complete sets of financial
statements of the enterprise and in condensed financial statements of interim
periods issued to shareholders. Statement 131 also requires that public
business enterprises report certain information about their products and
services, the geographic areas in which they operate and their major
customers.     
   
  In February 1998, the FASB issued Statement of Financial Accounting
Standards No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits" ("Statements 132"), which revises employers'
disclosures about pension and other postretirement benefit plans. Statement
132 does not change the measurement or recognition of those plans, but
requires additional information on changes in benefit obligations and fair
values of plan assets, and eliminates certain disclosures previously required
by SFAS Nos. 87, 88 and 106. Statement 132 is effective for financial
statements with fiscal years beginning after December 15, 1997.     
   
  The Combined Company has not determined what additional disclosures, if any,
may be required by the provisions of Statements 131 and 132, but does not
expect adoption of either statement to have a material effect on its results
of operations.     
   
  In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-5, "Reporting on the Costs of Start-Up
Activities," which requires costs of start-up activities and organization
costs to be expensed as incurred. The SOP is effective for financial
statements with fiscal years beginning after December 15, 1998, although
earlier application is encouraged. The adoption of the SOP is not expected to
have a material adverse effect on the Combined Company.     
 
YEAR 2000 STATEMENT
       
   
  The Combined Company is currently evaluating its computer systems to
identify potential problems relating to the Year 2000 date change. The
Combined Company does not expect the cost to modify its computer systems to
address Year 2000 issues will be material to its financial condition or
results of operations, and does not anticipate any material disruption in its
operations as a result of any Year 2000 issues. The Combined Company does not
have any information concerning the potential impact of Year 2000 issues on
any of its suppliers or customers. In the event that the Combined Company or
any of the Combined Company's significant suppliers or customers does not
successfully and timely address Year 2000 issues, the Combined Company's
business or operations could be adversely affected.

COMPARISON OF NINE MONTHS ENDED JANUARY 31, 1997 AND 1998     
   
  Revenue increased $235,000 or 2.7% from approximately $8.7 million for the
nine months ended January 31, 1997 to $8.9 million for the nine months ended
January 31, 1998. Revenue decreased $606,000 or 19.4% from approximately $3.1
million for the third quarter of fiscal 1997 to approximately $2.5 million
during the third quarter of fiscal 1998. This decrease in revenue was due to a
decline in customers and usage resulting from service disruptions caused by
the transfer of CSI's switching and billing functions into ITC's systems. CSI
experienced operational difficulties during this transfer process which
resulted in service disruptions for a number of customers. Although CSI's
revenue was adversely affected during this period, CSI believes that it has
resolved these difficulties.     
   
  CSI's cost of revenue decreased $301,000 or 5.3% from approximately $5.7
million in the nine months ended January 31, 1997 to approximately $5.4
million for the nine months ended January 31, 1998. As a percentage of
revenue, these costs decreased from 65.8% to 60.6% for the nine months ended
January 31, 1997 and 1998, respectively. As of March 1997, CSI had new
contractual commitments with Sprint reflecting more favorable rates that
resulted in improved gross margins during the nine months ended January 31,
1998.     
   
  Sales and marketing expense increased $471,000 or 31.6% from $1.5 million
for the nine months ended January 31, 1997 to $2.0 million for the nine months
ended January 31, 1998. As a percentage of revenue, these costs increased from
17.2% to 22.1% for the nine months ended January 31, 1997 and 1998,
respectively. The increase in absolute dollars was due in part to an increase
in independent sales agent commissions caused by the increase in revenue and
advertising expense and additional in-house sales personnel, while the
increase as a percentage of revenue was due primarily to an increase in
advertising expense and hiring of additional in-house sales personnel.     
   
  General and administrative expense increased $1.3 million or 96.3% from $1.3
million for the nine months ended January 31, 1997 to $2.6 million for the
nine months ended January 31, 1998. As a percentage of revenue, these costs
increased from 15.3% to 29.2% for the nine months ended January 31, 1997 and
1998, respectively. The significant increase in expenses is the result of CSI
building its administrative infrastructure during fiscal 1998 in anticipation
of significant growth. These expenses included costs associated with
relocating personnel and integrating operations with ITC's operations in Ft.
Lauderdale, Florida, costs associated with terminating former members of
senior management and hiring experienced executive management, and costs
associated with     
 
                                      33
<PAGE>
 
   
adding additional customer support and administrative personnel to support the
growth of CSI's operations. CSI also increased its reserve for bad debt by
$350,000, which was primarily associated with a receivable owed by a former
independent sales agent. CSI has implemented internal control procedures to
mitigate the risk of significant loss in the future from individual
independent sales agents. CSI continues to vigorously pursue the collections
of all bad debt expenses from former customers and independent sales agents.
    
       
   
  Depreciation and amortization expense increased $34,000 or 48.4% from
approximately $71,000 for the nine months ended January 31, 1997 to
approximately $105,000 for the nine months ended January 31, 1998. These costs
increased primarily as a result of CSI's higher fixed asset base during the
nine months ended January 31, 1998 as compared with the nine months ended
January 31, 1997.     
   
  Interest and debt discount expense increased $234,000, or 205% from
approximately $114,000 for the nine months ended January 31, 1997 to
approximately $348,000 for the nine months ended January 31, 1998. These
expenses primarily represent amortized costs associated with the December 1997
Financing. Interest and debt discount expense will increase significantly
until completion of this offering due to accrued interest and amortized costs
associated with the December 1997 Financing.     
   
  CSI did not record an income tax expense or benefit for the nine months
ended January 31, 1997 or 1998 but recorded valuation allowances to offset the
deferred tax asset due to the uncertainty of the ultimate realization of the
net operating loss carryforwards.     
   
  CSI had a net loss of approximately $37,000 for the nine months ended
January 31, 1997 compared to a net loss before extraordinary item of
approximately $1.5 million for the nine months ended January 31, 1998. The
increase in net loss before extraordinary items was due primarily to the
significant increase in general and administrative expense and debt financing
costs.     
   
  CSI recorded an extraordinary gain on extinguishment of debt totaling
$747,000, net of related expense, associated with the early repayment of notes
from proceeds of the December 1997 Financing.     
   
  CSI had a net loss of $37,000 for the nine months ended January 31, 1997
compared to a net loss of $770,000 for the nine months ended January 31, 1998.
The increase in net loss was due primarily to the significant increase in
general and administrative expense and debt financing costs partially offset
by the gain on extinguishment of debt.     
   
  CSI had basic loss per share of $   for the nine months ended January 31,
1997 compared to basic loss per share of $    for the nine months ended
January 31, 1998. The change in per share results was due primarily to an
increase in net loss and by an increase in weighted average shares
outstanding.     
   
  CSI had positive EBITDA of $148,000 for the nine months ended January 31,
1997 compared to negative EBITDA of $1.1 million for the nine months ended
January 31, 1998. The decrease in EBITDA was primarily due to the increase in
general and administrative expenses.     
   
COMPARISON OF FISCAL YEARS ENDED APRIL 30, 1996 AND 1997     
   
  Revenue increased $5.1 million or 76.0% from $6.7 million for fiscal 1996 to
$11.9 million for fiscal 1997. This increase was primarily due to growth in
the number of customers. The significant increase in revenue was primarily due
to CSI's efforts to increase its independent sales agent base in its target
markets.     
   
  Cost of revenue increased $1.8 million or 30.1% from $6.0 million for fiscal
1996 to $7.8 million for fiscal 1997. As a percentage of revenue, cost of
revenue decreased from 88.5% to 65.4%, respectively. Cost of revenue increased
at a lower rate than revenue as CSI recognized the benefit of more favorable
carrier rates.     
   
  Sales and marketing expenses increased $507,000 or 32.3% from $1.6 million
for fiscal 1996 to $2.1 million for fiscal 1997. As a percentage of revenue,
these costs decreased from 23.3% to 17.5% for fiscal 1996 and fiscal 1997,
respectively. The increase in absolute dollars was due primarily to
commissions due on increased revenue     
 
                                      34

while the decrease as a percentage of revenue was due primarily to revenue
increasing at a greater rate than marketing expense and costs associated with
in-house salespersons.     
   
  General and administrative expense increased $372,000 or 22.5% from $1.7
million for fiscal 1996 to $2.0 million for fiscal 1997. As a percentage of
revenue, these costs decreased from 24.5% to 17.1% for fiscal 1996 and fiscal
1997, respectively. The increase in costs were due to additional customer
support and administrative personnel hired to support the growth of CSI's
operations.     
   
  Depreciation and amortization expense increased $45,000 or 78.0% from
approximately $58,000 for fiscal 1996 to approximately $103,000 for fiscal
1997. These expenses increased primarily as a result of CSI's higher fixed
asset base in fiscal 1997 which was principally due to investments in
telecommunications equipment, infrastructure and facility expansion.     
   
  Interest expense increased $143,000 from approximately $19,000 for fiscal
1996 to approximately $162,000 for fiscal 1997. The increase in interest
expense was due primarily to the issuance of notes to satisfy carrier
obligations.     
   
  CSI did not record an income tax benefit in either fiscal 1996 or fiscal
1997 but recorded valuation allowances to offset the deferred tax asset due to
the uncertainty of the ultimate realization of the net operating loss
carryforwards.     
   
  The net loss decreased from $2.4 million for fiscal 1996 to $259,000 for
fiscal 1997. The decrease in net loss was primarily due to CSI's obtaining
more favorable carrier rates and increases in customer volume.     
   
  CSI had basic loss per share of $     for fiscal 1996 compared to basic loss
per share of $    for fiscal 1997. The decrease in basic loss per share was
due primarily to CSI's obtaining more favorable carrier rates and increases in
customer volumes as well as an increase in the weighted average number of
shares outstanding.     
   
  CSI had negative EBITDA of $2.5 million for fiscal 1996 compared to positive
EBITDA of $6,000 for fiscal year 1997. The increase in EBITDA was primarily
due to CSI's obtaining more favorable carrier rates, which improved gross
margin percentages.     
   
COMPARISON OF FISCAL YEARS ENDED APRIL 30, 1995 AND 1996     
   
  Revenue increased $4.9 million or 266.8% from $1.8 million for fiscal 1995
to $6.7 million for fiscal 1996. This increase was primarily due to growth in
the number of customers, which resulted from CSI's efforts to increase its
independent sales agent base in its target markets.     
   
  Cost of revenue increased $4.7 million or 359.4% from $1.3 million for
fiscal 1995 to $6.0 million for fiscal 1996 and as a percentage of revenue
increased from 70.6% to 88.5%, respectively. During fiscal 1996, CSI increased
minute volume in advance of its ability to secure more favorable volume
discount rates with its carriers.     
   
  Sales and marketing expense increased $1.0 million or 197.2% from $529,000
for fiscal 1995 to $1.6 million for fiscal 1996. As a percentage of revenue,
these costs decreased from 28.8% to 23.3% for fiscal 1995 and fiscal 1996,
respectively. The increase in absolute dollars was due primarily to
commissions on increased revenue while the decrease as a percentage of revenue
was due primarily to revenue increasing at a greater rate than marketing
expenses and costs associated with in-house salespersons.     
   
  General and administrative expense increased $1.0 million or 164.6% from
$624,000 for fiscal 1995 to $1.7 million for fiscal 1996. As a percentage of
revenue, these costs decreased from 34.0% to 24.5% for fiscal year 1995 and
fiscal 1996, respectively. The increase in absolute dollars was due to
additional customer support and administrative personnel hired to support the
growth of CSI's operations.     
       
                                      35

  Depreciation and amortization expense increased $39,000 or 202.7% from
approximately $19,000 for fiscal 1995 to approximately $58,000 for fiscal
1996. These expenses increased primarily as a result of CSI's higher fixed
asset base in fiscal 1996 which was principally due to investments in
telecommunications equipment, infrastructure and facility expansion.     
   
  Interest expense was approximately $19,000 for fiscal 1996 and was a nominal
amount in fiscal 1995. Interest expense was due primarily to the issuance of
notes payable to satisfy carrier obligations.     
   
  CSI did not record an income tax benefit in either fiscal 1995 or fiscal
1996 but recorded valuation allowances to offset the deferred tax asset due to
the uncertainty of the ultimate realization of the net operating loss
carryforwards.     
   
  The net loss increased from $633,000 for fiscal 1995 to $2.5 million for
fiscal 1996. The increase in net loss was primarily due to CSI's unfavorable
carrier rates and significant increase in operating expenses.     
   
  CSI had basic loss per share of $    for fiscal 1996 compared to basic loss
per share of $     for fiscal 1995. The increase in basic loss per share was
due primarily to an increase in CSI's net loss as well as an increase in the
weighted average number of shares outstanding.     
   
  CSI had negative EBITDA of $614,000 for fiscal 1995 compared to negative
EBITDA of $2.4 million for fiscal 1996. The decrease in EBITDA was due
primarily to a significant increase in operating expenses during fiscal 1996.
    
          
QUARTERLY RESULTS OF OPERATIONS     
   
  The following table sets forth certain quarterly financial data for the
seven quarters ended January 31, 1998. This quarterly information has been
derived from CSI's unaudited financial statements which, in the opinion of
CSI's management, reflect all adjustments (consisting only of normal recurring
adjustments) necessary for a fair presentation of the information for the
periods presented. Operating results for any one quarter are not necessarily
indicative of the results that may be expected in any future period.     
   
  CSI's quarterly operating results have fluctuated in the past and may
fluctuate significantly in the future as a result of a variety of factors,
some of which are outside CSI's control. These factors include demand for
international telecommunications services, capital expenditures and other
costs relating to the expansion of operations, the timing of new service
introductions by CSI or its competitors, market availability and acceptance of
new and enhanced versions of CSI's or its competitors' services, changes in
the mix of revenue, rates of customer acquisition and retention and general
economic conditions.

  CSI experienced declining revenue in the quarters ended October 31, 1997 and
January 1, 1998 in comparison to prior quarters. This decline was primarily a
result of a decline in customers and usage resulting from service disruptions
caused by the transfer of CSI's switching and billing functions into ITC's
systems. CSI experienced operational difficulties during this transfer process
which resulted in service disruptions for a number of customers. Although
CSI's revenue was adversely affected during this period, CSI believes that it
has resolved these difficulties.     
   
  Operating expenses have increased during each quarter, reflecting an
increase in general and administrative expense associated with the development
of CSI's administrative infrastructure. Installation, sales and marketing
expense has increased primarily due to commissions on increased revenue and
in-house sales personnel. CSI also increased its reserve for bad debt during
quarters ended October 31, 1997 and January 31, 1998, due to unpaid
receivables owed by a former independent sales agent. Interest expense
increased significantly during the quarter ended January 31, 1998, primarily
to non-cash financing activities in the quarter. CSI also recognized gain on
extinguishment of debt during the quarter ended January 31, 1998 related to
the repayment of notes using the proceeds of the December 1997 Financing.     
 
LIQUIDITY AND CAPITAL RESOURCES
   
  CSI's capital resources have been used to fund operating losses, debt
service and capital expenditures associated with development of its customer
base and the establishment and upgrade of its network infrastructure. Since
its inception, CSI has experienced net losses and negative cash flow from
operations. As of January 31, 1998, CSI had a working capital deficit of
approximately $3.0 million. CSI has satisfied its capital requirements
principally through a combination of sales of equity and debt securities,
borrowings from third parties (including its shareholders) and trade credit
extended by carriers. The proceeds from the issuance of stock and notes were
used for expansion of operations and general corporate purposes. During fiscal
1996 and fiscal 1997, CSI issued shares of its Common Stock for aggregate
proceeds of $537,000 and $111,000, respectively, and generated additional
working capital of $320,000 in fiscal 1997 through the issuance of convertible
notes. The notes bear interest at the rate of 10% per annum and mature two
years after issuance. In fiscal 1998, $95,000 of principal amount of such
notes were also issued. The notes are convertible into shares of Common Stock
at a conversion price equal to 90% of the average of the bid and asked price
on the day preceding the date of conversion. As of January 31, 1998, $385,000
of the convertible notes had been converted. In fiscal 1997, CSI also raised
$85,000 through the issuance of notes that bear interest at 15% per annum and
mature in September 1998. In December 1997, CSI issued Bridge Notes in the
principal amount of $2.8 million. The Bridge Notes bear interest at 10% per
annum and are due five days following the closing of this offering. CSI has
entered into employment agreements that obligate the Combined Company to pay
annual salaries of approximately $400,000. CSI also has an agreement to pay
certain royalties to Gary Kamienski relating to CSI's LINK-US technology.     
   
  As a result of CSI's operating losses, working capital has not always been
sufficient to satisfy CSI's obligations, and CSI from time to time has been in
arrears on its payment obligations to its carriers. During fiscal 1996 and
fiscal 1997, CSI incurred usage fees, which it was unable to pay on a current
basis, with two of its primary carriers totaling approximately $2.0 million.
In February 1997, CSI restructured these obligations and converted all amounts
into notes bearing interest ranging from 10% to 12% payable in monthly
installments ranging from $40,000 to $123,000 through August 1997 and $40,000
thereafter through January 2001. In December 1997, all carrier obligations
were paid in full from the proceeds of the December 1997 Financing. CSI
anticipates that its minimum commitments to carriers (exclusive of any carrier
commitments of GlobalTel or ITC) will be approximately $4.2 million and $1.5
million for fiscal 1998 and fiscal 1999, respectively. As of March 31, 1998,
CSI was again in arrears on carrier payments due to one carrier of
approximately $780,000. The Combined Company intends to use a portion of the
proceeds of this offering to repay such amount. There can be no assurance CSI
will not be required to pay a penalty to this or any other carrier or that CSI
will not be in default of its obligations to its carriers in the future.     
   
  Net cash used in operating activities was approximately $882,000 for the
nine months ended January 31, 1998, as compared to cash provided by operating
activities of approximately $473,000 for the nine months ended January 31,
1997. Adjustments to the $770,000 net loss for the period to reconcile to net
cash used in operating

activities consisted primarily of a $747,000 extraordinary gain on
extinguishment of debt, $208,000 in amortized costs associated with the
December 1997 Financing and $105,000 in depreciation and amortization. The
decrease in cash provided from operating activities was primarily due to a
$733,000 increase in net loss for such period partially offset by an increase
in accounts payable and accrued expenses. Net cash used in investing
activities was approximately $362,000 for the nine months ended January 31,
1998, compared to approximately $167,000 for the nine months ended January 31,
1997. The increase was primarily due to acquisition deposits paid to ITC. Net
cash provided by financing activities was approximately $1.7 million for the
nine months ended January 31, 1998, compared to cash used in financing
activities of approximately $314,000 for the nine months ended January 31,
1997. The increase in cash provided by financing activities was primarily due
to receipt of proceeds from the Bridge Notes from the December 1997 Financing,
issuance of stock, net of cash payments to acquire treasury stock from two
former CSI employees, and repayment of a carrier note.     
   
  Net cash provided by operating activities was approximately $730,000 for
fiscal 1997, compared to cash used in operating activities of approximately
$362,000 for fiscal 1996. The increase in cash provided was primarily due to a
$2.3 million decrease in net loss and by an increase in accounts payable of
approximately $911,000. Net cash used in investing activities was
approximately $244,000 for fiscal 1997, compared to approximately $223,000 for
fiscal 1996. The increase was primarily due to acquisition deposits paid to
ITC. Net cash used in financing activities was approximately $397,000 for
fiscal 1997, compared to cash provided by financing activities of
approximately $560,000 for fiscal 1996. The increase in cash used was
primarily due to repayment of notes, net of proceeds from the sale of stock
and issuances of additional notes.     
   
  Net cash used in operating activities was approximately $362,000 for fiscal
1996, as compared to cash used in operating activities of approximately
$398,000 for fiscal 1995. The decrease in cash used was primarily due to an
increase in accounts payable of approximately $2.7 million partially offset by
a $1.9 million increase in net loss. Net cash used in investing activities was
approximately $223,000 for fiscal 1996, compared to approximately $54,000 for
fiscal 1995. The increase was primarily due to the acquisition of switching
equipment. Net cash provided by financing activities was approximately
$560,000 for fiscal 1996, compared to cash provided by financing activities of
approximately $526,000 for fiscal 1995. The increase in cash provided was
primarily due to proceeds from the sale of stock and issuances of notes.

COMPARISON OF YEARS ENDED DECEMBER 31, 1996 AND 1997     
   
  Revenue increased $3.8 million or 41.7% from $9.1 million in 1996 to $12.9
million in 1997. Revenue from call-reorigination increased $262,000 or 3.1%
from $8.3 million in 1996 to $8.6 million in 1997. This increase resulted from
higher usage by existing customers, the addition of new customers and the
expansion of GlobalTel's agent network. Following the relocation of
GlobalTel's primary switching platform to Los Angeles in late 1996, GlobalTel
also commenced selling international long-distance minutes on a wholesale
basis to several carriers. Revenue from carriers, which commenced in October
1996, increased to $4.3 million in 1997. Call-reorigination and carrier
revenue represented 66.9% and 33.1% of GlobalTel's revenue, respectively, in
1997.     
   
  Cost of revenue increased $2.9 million or 35.7% from $8.2 million in 1996 to
$11.2 million in 1997. This increase is primarily attributable to increased
transmission costs associated with greater calling volume. As a percentage of
revenue, cost of revenue decreased from 90.1% to 86.9% in 1996 and 1997,
respectively. This decrease in percentage of revenue is primarily attributable
to a decrease in the costs associated with implementation of least-cost call
routing in late 1996. This decrease was offset, in part, by higher cost of
revenue as a percentage of revenue attributable to GlobalTel's carrier
revenue.     
   
  Sales and marketing expense increased $106,000 or 15.5% to $788,000 in 1997
from $682,000 in 1996. This increase is primarily attributable to increased
sales commissions and a higher effective commission rate. Substantially all of
GlobalTel's sales commissions are related to call-reorigination sales
generated by independent sales agents. As a percentage of revenue, sales and
marketing expense declined from 7.5% to 6.1% in 1996 and 1997, respectively,
resulting in part from higher levels of carrier sales not requiring
advertising or sales commissions.     
   
  General and administrative expense increased $1.3 million or 22.4% from $5.8
million in 1996 to $7.1 million in 1997. This increase is primarily
attributable to $670,000 in expense that was charged to operations and
associated with GlobalTel's discontinued public offering and $447,000 of non-
cash compensation costs. General and administrative expense also increased due
to compensation costs resulting from increased staffing levels. As a
percentage of revenue, general and administrative expense declined from 63.1%
to 55.3% in 1996 and 1997, respectively. This decrease is primarily
attributable to economies of scale associated with GlobalTel's ability to
spread general and administrative expense across a broader revenue base.

  Depreciation and amortization increased $155,000 or 158.2% from $98,000 in
1996 to $253,000 in 1997. This increase is primarily attributable to the
depreciation of capital assets acquired in late 1996 and in 1997, including a
new voice switching platform, facility improvements, fax gateway switching
platform and an electronic billing and customer interface system.     
   
  Interest expense and amortization of debt discount increased $1.1 million or
508.0% from $225,000 in 1996 to $1.4 million in 1997. This increase is
primarily attributable to an increase in GlobalTel's outstanding indebtedness,
together with financing costs associated with the incurrence of additional
debt. Also included in 1997 is $440,000 of additional amortized debt expense
as a result of the conversion of a portion of GlobalTel's indebtedness to
common stock, issuance of certain GlobalTel notes, and amendment of certain
stock warrant agreements.     
   
  GlobalTel did not record a provision for income taxes for either 1996 or
1997 as a full valuation allowance was recorded for both periods to offset net
deferred tax assets due to the uncertainty of the ultimate realization of the
net operating loss carryforwards.     
   
  GlobalTel had a net loss of $5.9 million for 1996 and $7.9 million for 1997.
The increase in net loss was due primarily to the significant increase in
general and administrative expense and debt financing costs.     
   
  GlobalTel had basic loss per share of $   for 1996 and basic loss per share
of    for 1997. The increase in basic loss per share was due primarily to an
increase in net loss, offset by an increase in weighted average shares
outstanding.     
   
  GlobalTel had negative EBITDA of $5.5 million for 1996 compared to negative
EBITDA of $6.2 million for 1997. The increase in negative EBITDA was primarily
due to the increase in general and administrative expense.     
   
COMPARISON OF YEARS ENDED DECEMBER 31, 1995 AND 1996     
   
  Revenue increased $7.0 million or 333.3% from $2.1 million in 1995 to $9.1
million in 1996 . Revenue from call-reorigination increased $6.2 million or
295.2% from $2.1 million in 1995 to $8.3 million in 1996. The increase in
call-reorigination revenue was primarily due to increased usage by existing
customers and the addition of new customers. Revenue in 1996 also included
$793,000 of sales to carriers commencing in October 1996. GlobalTel's revenue
from call-reorigination and carrier sales represented approximately 91.3% and
8.7%, respectively, of GlobalTel's revenue in 1996.     
   
  Cost of revenue increased $6.3 million or 331.6% from $1.9 million in 1995
to $8.2 million in 1996. This increase is primarily attributable to increased
transmission costs associated with greater calling volume. As a percentage of
revenue, these costs decreased from 91.3% to 90.1% in 1995 and 1996,
respectively, primarily as a result of better network utilization offset in
part by carrier revenue.     
   
  Sales and marketing expense increased $444,000 or 186% from $238,000 in 1995
to $682,000 in 1996. This increase was primarily attributable to higher sales
commissions and advertising costs. The increase in sales commissions is
attributable to increased levels of sales generated by agents as well as an
increase in the effective commission rate. As a percentage of revenue, sales
and marketing expense decreased from 11.3% to 7.5% in 1996, respectively. This
decrease is primarily attributable to economies of scale associated with
GlobalTel's ability to spread costs of operations across a broader revenue
base.     
   
  General and administrative expense increased $4.3 million or 286.7% from
$1.5 million in 1995 to $5.8 million in 1996. This increase is primarily
attributable to the costs, including wages, travel and facilities, associated
with the addition of administrative, technical and customer support personnel
as GlobalTel developed its management team and network. During this period
GlobalTel also incurred professional, consulting and facilities expense
associated with the establishment of its relationship with Equant and the
development of     
 
                                      40
<PAGE>
 
   
GlobalTel's enhanced services. General and administrative expense declined as
a percentage of revenue from 72.7% to 63.1% in 1995 and 1996, respectively.
This decrease is primarily attributable to economies of scale associated with
GlobalTel's ability to spread general and administrative expense across a
broader revenue base.     
          
  Depreciation and amortization decreased $13,000 or 11.8% from $111,000 in
1995 to $98,000 in 1996. This decrease resulted from a one-time write-off in
1995 of certain organizational costs.     
   
  Interest expense increased $191,000 or 561.8% from $34,000 in 1995 to
$225,000 in 1996. This increase is primarily attributable to an increase in
GlobalTel's outstanding indebtedness, together with the amortization of debt
issuance costs.     
   
  GlobalTel did not record a provision for income taxes for either 1996 or
1995 as a full valuation allowance was recorded for both periods to offset net
deferred tax assets due to the uncertainty of the ultimate realization of net
operating loss carryforwards.     
   
  GlobalTel had a net loss of $1.7 million for 1995 and a net loss of $5.9
million for 1996. The increase in net loss was due primarily to the
significant increase in general and administrative expenses and increased debt
financing costs.     
   
  GlobalTel had basic loss per share of $   for 1995 compared to basic loss
per share of $   for 1996. The change in basic loss per share was due
primarily to an increase in net loss.     
   
  GlobalTel had negative EBITDA of $1.6 million for 1995 compared to negative
EBITDA of $5.5 million for 1996. The increase in negative EBITDA was primarily
due to the increase in general and administrative expense.     
          
QUARTERLY RESULTS OF OPERATIONS     
   
  The following table sets forth certain quarterly financial data for the
eight quarters ended December 31, 1997. This quarterly information has been
derived from unaudited consolidated financial statements which, in the opinion
of GlobalTel's management, reflect all adjustments (consisting only of normal
recurring adjustments) necessary for a fair presentation of the information
for the periods presented. Operating results for any one quarter are not
necessarily indicative of the results that may be expected in any future
period.     
   
  GlobalTel's quarterly operating results have fluctuated in the past and may
fluctuate significantly in the future as a result of a variety of factors,
some of which are outside GlobalTel's control. These factors include demand
for international telecommunications services, capital expenditures and other
costs relating to the expansion of operations, the timing of new product
introductions by GlobalTel or its competitors, market availability and
acceptance of new and enhanced versions of GlobalTel's or its competitors'
services, changes in the mix of revenue, customer acquisition and retention
and general economic conditions.

  Following the relocation of GlobalTel's switch to Los Angeles in the fourth
quarter of 1996, GlobalTel commenced reselling long-distance minutes to
certain carriers. Sales to carriers accounted for a major portion of the 45.3%
and 32.6% increase in total revenue for the fourth quarter of 1996 and the
first quarter of 1997, respectively. Revenue from carrier sales increased $1.2
million or 152.2% to $2.0 million in the first quarter of 1997 from $793,000
in the fourth quarter of 1996. As a percentage of revenue, GlobalTel's cost of
revenue increased as a percentage of revenue in the third and fourth quarters
of 1996 due to lower margins associated with carrier sales. In the first
quarter of 1997, GlobalTel raised prices on sales to carrier customers, while
cost of revenue as a percentage of revenue declined to 86.9% despite the
increasing proportion of carrier sales.     
   
  GlobalTel experienced declining revenue in the quarters ended June 30, 1997,
September 30, 1997, and December 31, 1997. This decline was primarily a result
of GlobalTel's decision in May 1997 to temporarily de-emphasize its carrier
business. Due to the lengthy payment cycles GlobalTel had experienced with
certain of its carrier customers and GlobalTel's relatively low cash reserves,
GlobalTel reduced its carrier sales in order to limit its credit risk and to
reduce its effective carrying costs associated with carrier accounts
receivable. Specifically, GlobalTel ceased doing business with two carriers
and reduced its level of business with several others, resulting in a decline
in carrier revenue from $2.0 million in the quarter ended March 31, 1997 to
$473,000 in the quarter ended December 31, 1997. In order to continue to
capitalize on the benefits of greater network utilization and increased buying
power, GlobalTel anticipates increasing the level of carrier sales in the next
12 months as GlobalTel seeks to develop business relationships with additional
carriers.     
   
  Additionally, call-reorigination revenue declined moderately during the
second, third, and fourth quarters of 1997. Due to anticipated capacity
constraints and limited access to multiple carriers, GlobalTel relocated its
primary switching platform from Las Vegas to Los Angeles in late 1996.
GlobalTel experienced technical and operational difficulties in connection
with this relocation process which resulted in service disruptions for a
number of customers. Although GlobalTel's sales were adversely affected during
this period, GlobalTel believes that it resolved these difficulties by June
1997. Increased competitive pressures encountered by some of GlobalTel's
independent sales agents also contributed to the decline in revenue during
these quarters. During the second half of 1997 GlobalTel installed a new
switching platform which became fully operational on November 1, 1997,
enabling GlobalTel to offer a wider variety and more competitive package of
services to its independent sales agents and customers.     
   
  GlobalTel also experienced an increase in cost of revenue as a percentage of
revenue in the quarter ending December 31, 1997. This increase was primarily
due to an increase in transmission costs resulting from the temporary re-
routing of traffic previously carried by one of its principal long-distance
carriers after this carrier ceased providing services to GlobalTel. General
and administrative expense increased in the quarter ending December 31, 1997
primarily due to professional fees charged to operations and relating to
GlobalTel's discontinued public offering. In addition, interest expense
increased significantly in the quarter ending December 31, 1997, resulting
primarily from non-cash financing activities in the quarter.     
   
LIQUIDITY AND CAPITAL RESOURCES     
   
  GlobalTel's capital resources have been used to fund operating losses, debt
service and capital expenditures associated with development of its customer
base and the establishment and upgrade of its network infrastructure. Since
its inception, GlobalTel has experienced net losses and negative cash flow
from operations. As of December 31, 1997, GlobalTel had a working capital
deficit of approximately $4.9 million. Through December 31, 1997, GlobalTel
had met these capital requirements largely through financing activities that
included $2.7 million in net proceeds from the sale of Common Stock, $1.0
million in net proceeds from the sale of Preferred Stock, $5.2 million in net
borrowings from shareholders and others represented by promissory notes (the
"Notes"), as well as revenue from operations. See "Certain Transactions." At
December 31, 1997, Notes aggregating approximately $7.0 million remained
outstanding, of which $1.8 million will mature prior to December 31, 1998.
Substantially all of the Notes accrue interest at the rate of 10% per annum,
increasing to 12% when the Notes become past due. Notes outstanding at
December 31, 1997, with an aggregate principal amount of $2.7 million are
convertible at the option of the holders into an aggregate of         shares
of     
 
                                      42
<PAGE>
 
   
Common Stock, assuming an initial public offering price of $     per share.
Warrants to purchase an aggregate of         shares of Common Stock were
issued in connection with the issuance of the Notes, all of which remained
outstanding at December 31, 1997. Also, in September 1997, deferred salaries
aggregating $1.2 million were converted into warrants to purchase    shares of
Common Stock. In October 1997, GlobalTel obtained an additional $550,000 in
connection with the issuance of notes to four individuals. These notes bear
interest at a rate of 10% per annum, are due in full on March 1, 1999, and are
convertible at any time prior to maturity at the fair market value per share
of Common Stock in effect as of the date of conversion. Warrants exercisable
for an aggregate of    shares of Common Stock at an exercise price of $    per
share were granted in this round of financing.     
   
  In November 1997 GlobalTel obtained an additional $325,000 in connection
with the issuance of notes to three individuals. These notes bore interest at
10% per annum and were repaid in full from the proceeds of certain notes
issued in November and December 1997. In addition, each holder of these notes
will receive, following the closing of this offering, shares of Common Stock
equal to one-half of the principal amount of such holder's note divided by the
initial public offering price of the Common Stock.     
   
  In November and December 1997 GlobalTel obtained approximately $3.0 million
in connection with the issuance of additional notes. These GlobalTel Full
Coverage Notes bear interest at the rate of 10% per annum and will be repaid
from proceeds of this offering.     
       
   
  As a result of GlobalTel's operating losses, available working capital has
not always been sufficient to satisfy GlobalTel's obligations and GlobalTel
from time to time has been in arrears on payment obligations to its carriers.
In October 1997, GlobalTel failed to pay amounts due to one of its principal
long-distance carriers within the time period that this carrier customarily
had required payment. As a result, this carrier ceased providing services to
GlobalTel and, under the terms of its agreement with GlobalTel, could demand a
termination payment of up to $1.2 million. GlobalTel was able to re-route
traffic that previously had been carried by this carrier without any
interruption in service to GlobalTel's customers. In December 1997, after
GlobalTel paid this carrier a substantial portion of the amounts past due,
services were restored. GlobalTel has negotiated the payment terms of the
remaining balance owed and does not believe that it will be required to pay an
amount in excess of that owed for carrier services provided. As of March 31,
1998, GlobalTel was in arrears on approximately $641,000 due to this carrier.
There can be no assurance that GlobalTel will not be required to pay a penalty
to this or any other carrier or that GlobalTel will not be in default of its
obligations to its carriers in the future.     
       
   
  Net cash used in operating activities was $5.1 million for 1997, as compared
to net cash used in operating activities of $2.6 million for 1996. The
increase in net cash used in operating activities was due primarily to a $2.0
million increase in net loss as well as a $3.3 million decrease in trade
accounts payable, accrued liabilities and notes payable. Net cash used in
investing activities was $667,000 for 1997, as compared to net cash used in
investing activities of $688,000 for 1996. Investing activities for 1997 and
1996 primarily represent capital expenditures for hardware and software. Net
cash provided by financing activities was $6.2 million for 1997, as compared
to net cash provided by financing activities of $3.0 million for 1996.
Financing activities in 1997 and 1996 primarily represent proceeds from the
issuance of bridge loans and Series A Convertible Preferred Stock in 1997.
       
  Net cash used in operating activities was $2.6 million for 1996, as compared
to net cash used in operating activities of $1.0 million for 1995. The
increase in net cash used in operating activities was due primarily to a $4.1
million increase in net loss which was partially offset by a $3.1 million
increase in trade accounts payable, accrued liabilities and notes payable. Net
cash used in investing activities was $688,000 for 1996, as compared to net
cash used in investing activities of $522,000 for 1995. Investing activities
for 1996 primarily represent capital expenditures for hardware and software
while investing activities for 1995 includes $260,000 in capital equipment and
$262,000 in capitalized organization costs. Net cash provided by financing
activities was $3.0 million for 1996, as compared to net cash provided by
financing activities of $2.0 million for 1995. Financing activities in 1996
primarily represent proceeds from the issuance of bridge loans while investing
activities in 1995 primarily represent proceeds from the issuance of common
stock.

RESULTS OF OPERATIONS
   
  Due to the pendency of the ITC Acquisition, ITC's financial statements are
being presented for the period ending October 31, 1997. The statement of
operations data for the ten months ended October 31, 1997 is therefore not
directly comparable to the statement of operations data for the year ended
December 31, 1996. The results of operations for the ten-month period ended
October 31, 1997 may also not be reflective of results achieved in the 12
months ended December 31, 1997 and the three months ended December 31, 1996 is
not directly comparable to the three months ended January 31, 1998. The
following table sets forth, for the periods indicated, the percentage
relationship to revenue of certain items in ITC's statements of operations:

COMPARISON OF THREE MONTHS ENDED DECEMBER 31, 1996 TO THE THREE MONTHS ENDED
JANUARY 31, 1998     
          
  Revenue increased $907,000 or 46.7% from approximately $1.9 million for the
three months ended December 31, 1996 to approximately $2.8 million for the
three months ended January 31, 1998. The increase is due primarily to an
increase in customers and customer usage. During this period of time, the
number of customers increased due to additions in ITC's independent sale agent
base as well as the improved performance of the existing independent sales
agent base.     
   
  Cost of revenue increased $920,000 or 72.2% from approximately $1.3 million
for the three months ended December 31, 1996 to approximately $2.2 million for
the three months ended January 31, 1998. As a percentage of revenue, these
costs increased from 65.6% to 77.0% for the periods ended December 31, 1996
and January  31, 1998, respectively. The increase in cost of revenue is due to
an increase in transmission costs directly related to usage. The increased
cost of revenue as a percentage of total revenue was due to an increase in
revenue from sales to carriers and resellers, which has lower gross margins.
       
  Sales and marketing expense increased $34,000 or 16.2% from approximately
$210,000 for the three months ended December 31, 1996 to approximately
$244,000 for the three months ended January 31, 1998. As a percentage of
revenue, sales and marketing expense decreased from 10.8% to 8.6% for the
periods ended December 31, 1996 and January 31, 1998, respectively. The
decrease was due primarily to higher levels of carrier and reseller sales not
requiring advertising and sales commissions.

  General and administrative expense decreased $18,000 or 3.6% from $494,000
for the three months ended December 31, 1996 to $476,000 for the three months
ended January 31, 1998. The decrease in these costs was due primarily to lower
officers' compensation.     
   
  Depreciation expense increased $7,000 or 31.8% from approximately $22,000
for the three months ended December 31, 1996 to approximately $29,000 for the
three months ended January 31, 1998. These costs increased primarily as a
result of ITC's higher fixed asset base during the three months ended January
31, 1998.     
   
  Interest expense increased $10,000 or 200.0% from approximately $5,000 for
the three months ended December 31, 1996 to approximately $15,000 for the
three months ended January 31, 1998. The increase in interest expense was due
primarily to a capital lease obligation incurred to acquire telecommunications
equipment.     
   
  ITC did not record an income tax benefit for the three months ended January
31, 1998 but recorded valuation allowances to offset the deferred tax asset
due to the uncertainty of the ultimate realization of the net operating loss
carryforwards. ITC recorded an income tax expense of $4,000 for the year ended
December 31, 1996.     
   
  ITC reported a net loss of approximately $97,000 for the three months ended
January 31, 1998 compared to net loss of approximately $56,000 for the three
months ended December 31, 1996.     
   
COMPARISON OF YEAR ENDED DECEMBER 31, 1996 TO THE TEN MONTHS ENDED OCTOBER 31,
1997     
          
  Revenue increased $451,000 or 5.9% from approximately $7.6 million for the
year ended December 31, 1996 to approximately $8.1 million for the ten months
ended October 31, 1997. The increase is due primarily to an increase in
customers and customer usage. During this period of time, the number of
customers increased due to additions in ITC's independent sale agent base as
well as the improved performance of the existing independent sales agent base.
       
  Cost of revenue increased $1.7 million or 33.9% from approximately $5.1
million for the year ended December 31, 1996 to approximately $6.8 million for
the ten months ended October 31, 1997. As a percentage of revenue, these costs
increased from 66.7% to 84.3% for the periods ended December 31, 1996 and
October 31, 1997, respectively. The increase in cost of revenue is due to an
increase in transmission costs directly related to usage as well as a dispute
with a carrier. The increased cost of revenue as a percentage of total revenue
was due to an increase in revenue from sales to carriers and resellers, which
has lower gross margin percentages, and an increase in costs associated with
the carrier dispute. See "Business--Legal Proceedings."     
   
  Sales and marketing expense decreased $384,000 or 34.9% from approximately
$1.1 million for the year ended December 31, 1996 to approximately $715,000
for the ten months ended October 31, 1997. As a percentage of revenue, sales
and marketing expense decreased from 14.5% to 8.9% for the periods ended
December 31, 1996 and October 31, 1997, respectively. The decrease was due
primarily to higher levels of carrier and reseller sales not requiring
advertising and sales commissions.     
   
  General and administrative expense remained relatively constant at $1.4
million for the year ended December 31, 1996 and $1.4 million for the ten
months ended October 31, 1997. The similarity in these costs was due primarily
to the different length of the time periods presented.     
   
  Depreciation expense increased $4,000 or 5.8% from approximately $69,000 for
the year ended December 31, 1996 to approximately $73,000 for the ten months
ended October 31, 1997. These costs increased primarily as a result of ITC's
higher fixed asset base during the ten months ended October 31, 1997 as
compared with the year ended December 31, 1996.     
   
  Interest and other income decreased $26,000 or 29.5% from approximately
$88,000 for the year ended December 31, 1996 to approximately $62,000 for the
ten months ended October 31, 1997. The decrease in     
 
                                      45
<PAGE>
 
   
interest and other income was due primarily to an increase in other expenses
related to a loss on the sale of equipment and an increase in interest expense
related to a capital lease obligation. ITC had consulting fees totaling
approximately $113,000, net of related consulting expenses, which it received
from CSI for assistance in the settlement of a dispute with a carrier.     
   
  ITC did not record an income tax benefit for the ten months ended October
31, 1997 but recorded valuation allowances to offset the deferred tax asset
due to the uncertainty of the ultimate realization of the net operating loss
carryforwards. ITC recorded an income tax expense of $4,000 for the year ended
December 31, 1996.     
   
  ITC reported a net loss of approximately $850,000 for the ten months ended
October 31, 1997 compared to net income of approximately $7,000 for the year
ended December 31, 1996. The net loss includes a $1.1 million claim against
ITC by a carrier for usage charges, a portion of which ITC is disputing.     
   
COMPARISON OF THE YEARS ENDED DECEMBER 31, 1995 AND 1996     
   
  Revenue decreased $594,000 or 7.3% from approximately $8.2 million for 1995
to approximately $7.6 million for 1996. The decrease is due primarily to a
decrease in customers resulting from the loss of a significant independent
sales agent.     
   
  Cost of revenue decreased $337,000 or 6.2% from approximately $5.4 million
for 1995 to approximately $5.1 million for 1996. As a percentage of revenue,
these costs increased from 65.9% to 66.7% for 1995 and 1996, respectively. The
decrease in cost of revenue is due to a decrease in transmission costs
directly related to usage resulting from a decrease in customer base. The
increased cost of revenue as a percentage of total revenue was due to an
increase in revenue from sales to carriers and resellers.     
   
  Sales and marketing expense decreased $121,000 or 9.9% from approximately
$1.2 million for 1995 to approximately $1.1 million for 1996. As a percentage
of revenue, sales and marketing expense decreased from 14.9% to 14.5% for 1995
and 1996, respectively. This decrease was due primarily to higher levels of
carrier and reseller sales not requiring advertising and sales commissions.
       
  General and administrative expense increased $297,000 or 25.8% from $1.1
million for 1995 to $1.4 million for 1996. The increase in this expense was
due primarily to an increase in officers' compensation.     
   
  Depreciation expense increased $16,000 or 30.2% from approximately $53,000
for 1995 to approximately $69,000 for 1996. This expense increased primarily
as a result of ITC's higher fixed asset base during 1996 as compared with
1995.     
   
  Interest and other income/expense increased $112,000 from a net expense of
approximately $24,000 for 1995 to net other income of approximately $88,000
for 1996. The increase in interest and other income was due primarily to the
receipt of consulting fees totaling approximately $113,000, net of related
consulting expenses.     
   
  ITC recorded valuation allowances to offset the deferred tax asset due to
the uncertainty of the ultimate realization of the net operating loss
carryforwards. ITC recorded an income tax expense of $21,000 and $4,000 for
1995 and 1996, respectively.     
   
  ITC reported net income of approximately $344,000 for 1995 compared to net
income of approximately $7,000 for 1996. The decrease in net income is due
primarily to a decrease in gross margin, the loss of a significant independent
sales agent and an increase in general and administrative expense related to
officers' compensation.

LIQUIDITY AND CAPITAL RESOURCES
   
  Net cash provided by operating activities was approximately $205,000 for the
three months ended January 31, 1998, compared to cash used in operating
activities of approximately $143,000 for the three months ended December 31,
1996. The increase in cash provided by operating activities was due primarily
to the increase in accounts payable and a payable due to CSI under the
Reciprocal Telecommunications Agreement, net of an increase in trade
receivables related primarily to an increase in revenue from the comparable
period in 1996. Net cash used in investing activities totaling $10,000 during
the three months ended January 31, 1998 was due primarily to additional
equipment purchases. Net cash used in financing activities totaling $65,000
during the three months ended January 31, 1998 was due to payments on capital
lease obligations.     
   
  Net cash provided by operating activities was approximately $626,000 for the
ten months ended October 31, 1997, compared to cash provided by operating
activities of approximately $286,000 for the year ended December 31, 1996. The
increase in cash provided by operating activities was primarily due to a net
loss of $850,000 offset by an increase in accounts payable of $1.2 million and
a decrease in accounts receivable of $180,000. Net cash provided by investing
activities was approximately $242,000 for the ten months ended October 31,
1997, compared to cash used in investing activities of approximately $29,000
for the year ended December 31, 1996. The increase was primarily due to
proceeds received from the sale of telecommunications equipment. Net cash used
in financing activities was approximately $238,000 for the ten months ended
October 31, 1997, compared to cash used in financing activities of
approximately $186,000 for the year ended December 31, 1996. The change was
due primarily to an increase in capital lease payments related to the
acquisition of telecommunications equipment.     
   
  Net cash provided by operating activities was approximately $286,000 for
1996, compared to cash provided by operating activities of approximately
$533,000 for 1995. The decrease in cash provided by operating activities was
primarily due to a decrease in net income. Net cash used in investing
activities was approximately $29,000 for 1996, compared to cash used in
investing activities of approximately $152,000 for 1995. The decrease was
primarily due to fewer equipment purchases in 1996. Net cash used in financing
activities was approximately $186,000 for 1996, compared to cash used in
financing activities of approximately $291,000 for 1995. The decrease was due
primarily to proceeds from loan payable.

                                   BUSINESS
   
OVERVIEW     
   
  The Combined Company is a growing provider of international
telecommunications services offering long distance, calling cards and enhanced
voice and data services. With more than 25,500 customers in over 170
countries, the Combined Company primarily serves markets that have been
historically underserved by large telecommunications providers and ITOs. The
Combined Company presently focuses on international call-reorigination,
capitalizing on the arbitrage opportunity created by differences between U.S.
and international long-distance rates. Going forward, the Combined Company
intends to leverage the expertise derived from, and capitalize on the
established customer base generated by, its call-reorigination business to
provide higher margin telecommunications services such as call-through,
enhanced fax and business grade Internet services.     
   
  The Combined Company's telecommunications services are marketed and sold
through a network of independent sales agents, strategic relationships and in-
house direct marketing. The Combined Company relies primarily on over 170
independent sales agents that cover over 170 countries. GlobalTel has an
exclusive agreement with the International Business Network for World Commerce
and Industry, Ltd. ("IBNET"), the managing member of the Consortium of Global
Commerce, under which IBNET will market the services of GlobalTel, and
ultimately the Combined Company, through several thousand individual chambers
of commerce located in over 200 countries. In addition, GlobalTel has a
strategic relationship with Novell that provides it with a distribution
channel for its services, and ultimately those of the Combined Company,
through a select number of Novell's network of over 25,000 value-added
resellers. The Combined Company intends to pursue additional strategic
relationships and to expand its sales channels. The Combined Company's also
markets and sells through its small in-house sales staff, which is responsible
for call-reorigination sales and carrier resales.     
   
  The Combined Company has a broad customer base including foreign offices of
multinational corporations, including Nike Inc., Microsoft Corporation,
Mitsubishi Corporation and Chrysler Corporation; major international hotels,
including the Inter-Continental Hotel and the Copacabana Palace in Rio de
Janeiro, Brazil and Southern Sun Group's Holiday Inn Hotels in South Africa;
and embassies and international agencies, including the United States
embassies in Chile, Korea, Australia and the Ukraine and the United Nations
consulate in South Africa.     
          
  The GlobalTel Merger and the ITC Acquisition will enable the Combined
Company to rapidly obtain access to complementary infrastructure, personnel,
customer bases, sales and marketing resources and strategic relationships. The
integration of GlobalTel and ITC with CSI will afford the Combined Company a
greater opportunity to enter new markets, acquire new infrastructure, improve
its rate structure with carriers, and resell excess international capacity to
other carriers and resellers. The Combined Company intends to actively pursue
additional acquisitions of complementary international customer bases,
products and infrastructure.     
       
       
          
  The Combined Company provides its telecommunications services through its
(i) voice switching and global fax messaging infrastructure in Los Angeles,
California; (ii) voice switching and billing center in Ft. Lauderdale,
Florida; (iii) access to third party infrastructure through international
telecommunications carriers and through Equant, a global data network services
provider; and (iv) enhanced fax nodes in Hong Kong and Mexico City. The
Combined Company uses both off-the-shelf technologies, which provide
flexibility to adapt to the rapidly changing telecommunications environment,
and proprietary automated call processing technologies (DIAL and LINK-US),
which enhance the Combined Company's competitive position in serving larger,
high-volume customers.     
       
          
INDUSTRY AND MARKET OPPORTUNITY     
          
  Historically, telephone service within individual countries has been
monopolized by large, typically government-owned or protected entities, often
referred to as incumbent telephone operators ("ITOs"). As a result,
international callers have had little choice but to use the services provided
by and pay the prices charged by local ITOs. Deregulation, together with
decreases in the cost of providing services, and the introduction of     
 
                                      48
<PAGE>
 
   
more sophisticated enhanced services has made it possible for new entrants to
compete with the ITOs in providing international telecommunications services.
The resulting decrease in non-regulated rates has produced a resale market for
long-distance telecommunications services permitting companies to obtain
favorable volume-based rates from third party providers and to resell services
at competitive rates to other providers and users. These and other factors
have contributed to an increase in telecommunications usage and a
proliferation of enhanced telecommunications services in these markets. The
combination of a continually expanding global telecommunications market,
demand for lower prices and improved quality, and ongoing deregulation has
created competitive opportunities for new telecommunications companies in many
countries. According to the ITU, the international telecommunications industry
accounted for $52.8 billion in revenue and 61.9 billion minutes of long
distance international telephone calls worldwide in 1995. Based upon trends in
revenue growth from 1991 through 1995 measured by the ITU, the Combined
Company believes that international long distance telecommunications revenue
will surpass $76 billion by the year 2000. The projected revenue and growth
rates, as reported by the ITU, should not be relied upon as an indication of
the Combined Company's financial future.     
   
  Emerging Telecommunications Markets. The world's larger telecommunications
carriers (AT&T, Sprint, MCI, WorldCom, Deutsche Telecom AG, France Telecom)
have focused on developed telecommunications markets that are characterized by
high teledensity (ratio of telephone lines to inhabitants), an advanced stage
of deregulation, a large volume of international telecommunications traffic
and a concentration of large multinational corporations. These markets include
the United States, the United Kingdom, Germany, France and Japan. The Combined
Company focuses on what it characterizes as emerging telecommunications
markets, which are (i) smaller developed countries such as Argentina, Austria,
Brazil, Switzerland, Ireland, Singapore and South Africa, and (ii) markets
that typically have less developed telecommunications infrastructures, are in
an earlier stage of deregulation and have more monopolistic distribution
profiles. Based on data from the ITU, the Combined Company has calculated that
the approximately 145 countries that the Combined Company targets as emerging
telecommunications markets generated approximately 23.0 billion minutes in
outgoing international telecommunications traffic in 1995.     
          
  Convergence of Technology. Deregulation and evolving price competition have
coincided with technological innovation in the telecommunications industry.
New technologies such as fiber optic cable and improvements in digital
compression, computer software and call processing technology have contributed
to improvements in telecommunications quality and speed, increased
transmission capacities, and decreased transmission costs. For example, fiber
optic cable has dramatically increased the capacity and speed of telephone
lines and has eliminated capacity constraints as a technical barrier to entry
for new international telecommunications providers. The improved quality of
these new telephone lines also has facilitated the development of global
voice-mail and fax services and has enhanced data communication. Improvements
in computer software and processing technology have laid a foundation for
services such as itemized and multi-currency billing. In addition,
international debit and credit networks now permit customers to pay for long-
distance calls made from any telephone using a single home account. The
convergence of conventional telephony and computing technologies also has
created the opportunity for data networks, and computers in general, to become
primary telecommunications tools.     
   
  Private Networks and Emergence of the Internet. Until recently, the data
communications services offered by public carriers had limited security
features, were expensive and did not adequately ensure accurate and reliable
transmission. As a result, many corporations established private networks to
provide network-based services, such as transaction processing, to their
customers and to coordinate operations between employees, suppliers and
business partners. These private networks were frequently customized and thus
had the capability of providing organizations and users with tailored
performance, security, reliability and private-label branding. As the demand
for private networks has grown, there has been an increase in intranet
services and virtual private networks ("VPNs"), which combine the security of
a private network and the cost efficiencies of a public network.     
   
  Despite the benefits of private networks, they still have limitations that
reduce their effectiveness. These networks require leased telephone lines,
dedicated bandwidth and vendor-specific networking equipment. As a     
 
                                      49
<PAGE>
 
   
result, such networks are inherently expensive. The Combined Company believes
that the costs of maintaining a private network infrastructure and the risks
of investing in new technologies have precluded many small- and medium-sized
businesses from utilizing private networks, VPNs and intranet infrastructures.
       
  The emergence of the Internet and the widespread adoption of internet
protocol ("IP") as a data transmission standard, combined with deregulation of
the telecommunications industry and advances in telecommunications technology,
have significantly increased the attractiveness of providing data
communications over a public network. At the same time, the growth in
client/server computing, multimedia personal computers, on-line computing
services and network technologies has resulted in a large and growing group of
people who are accustomed to using networked computers for a variety of
purposes, including e-mail, electronic file transfers, on-line computing and
electronic financial transactions. These trends increasingly have led
businesses to explore opportunities to provide IP-based applications and
services within their organizations and to customers and business partners
outside the enterprise. The ubiquitous nature and relatively low cost of the
Internet have resulted in its widespread usage for certain applications, most
notably Internet access and electronic mail. However, use of the Internet for
mission-critical business applications has been impeded by the limited
security and unreliable performance inherent in the structure and management
of the Internet. Therefore, there is a market opportunity to offer a service
combining the best features of the Internet with the security of private
networks. The Combined Company intends to address this need with its business
grade Internet services.     
   
  Industry analysts expect the market size for both enhanced IP data services
and Internet access to continue to grow rapidly as businesses and consumers
increase their use of the Internet, intranets, and privately managed IP
networks. Industry sources project total Internet service provider ("ISP")
enhanced services revenue alone to grow from $197.8 million in 1996 to
approximately $11.4 billion in the year 2000, reaching average annual growth
of approximately 175.6% during that period.     
          
  Regulatory Environment. In a deregulated telecommunications market such as
the United States, carriers have multiple options for providing
telecommunications access to their customers. Carriers can establish switching
facilities, own or lease fiber optic cable or enter into operating agreements
with foreign carriers. In markets that have not deregulated or are slowly
deregulating, international long-distance carriers have used advances in
technology to develop innovative alternative access methods, such as call-
reorigination and other less regulated enhanced voice and data services. In
other countries, such as Japan and most European Union ("EU") member states,
where the deregulation process is more advanced but not complete, carriers
often are permitted to offer facilities-based data and facsimile services, as
well as limited voice services. As countries deregulate telecommunications
services, the market for alternative access methods typically becomes more
competitive as ITO's and other providers are permitted to offer a wider range
of facilities-based services on a more cost-competitive basis.     
   
  Call-reorigination, which is the most common form of alternative
international access, avoids the high international rates charged by the ITO
in a particular regulated country by providing a dial tone from a deregulated
country, typically the United States. To place a call using traditional call-
reorigination, a user dials a unique phone number to an international
carrier's switching center and then hangs up. The user then receives an
automated call back providing a dial tone from the United States, which
enables the user to complete the call using U.S. telecommunications
infrastructure. Technical innovations such as inexpensive dialers have enabled
telecommunications carriers to offer a newer, more advanced form of call-
reorigination (referred to as "transparent call-reorigination") that makes the
call-reorigination mechanics transparent to the customer. In addition, in-
country switching platforms have enabled carriers to offer "call-through"
services, allowing the customer direct access to a provider's network without
the need to reoriginate the call in the U.S.     
   
  The Combined Company believes that as deregulation occurs and competition
increases in markets around the world, the pricing advantage of call-
reorigination to most destinations will diminish relative to call-through
international long-distance service. The Combined Company also believes that
deregulation will continue to create opportunities for new entrants in
telecommunications services, particularly companies capable of meeting the
challenges presented by emerging telecommunications markets.

  World Trade Organization Agreement. On February 15, 1997, pursuant to the
WTO Agreement, which became effective on February 5, 1998, 69 members of the
WTO, including the United States, agreed to open their respective
telecommunications markets to competition and foreign ownership, and to
protect market entrants against anticompetitive behavior by dominant
telecommunications providers. By eroding the traditional monopolies held by
ITOs, many of which are wholly or partially government owned, implementation
of the WTO Agreement will allow U.S.-based providers the opportunity to
negotiate more favorable agreements with both ITOs and other providers in
emerging telecommunications markets. In addition, deregulation in certain
foreign countries will enable U.S.-based providers to establish local
switching and transmission facilities in order to terminate their own traffic
and carry international long distance traffic originating in those countries.
    
       
BUSINESS STRATEGY
   
  The Combined Company's objective is to become a leading provider of enhanced
telecommunications services in markets that historically have been underserved
by large telecommunications providers and ITOs. The Combined Company's
strategy to accomplish this objective includes the following key elements:
       
  Increase Penetration of Emerging Telecommunications Markets. The Combined
Company markets its services in emerging telecommunications markets that
typically have less developed telecommunications infrastructures, are in an
earlier stage of deregulation and have historically faced less competition
from larger telecommunications providers. The Combined Company believes that,
due to the more monopolistic distribution profile of these markets, customers
traditionally have been underserved and consequently are more receptive to
higher quality, competitively priced services. The Combined Company believes
that its experience in offering call-reorigination, combined with its
strategic marketing relationships and proprietary technologies, will enable
the Combined Company to more effectively penetrate these markets and provide
more sophisticated and higher margin telecommunications services.     
   
  Pursue and Implement Strategic Acquisitions. The Combined Company intends to
actively pursue and execute strategic acquisitions of complementary
international customer bases, products and infrastructure. GlobalTel and ITC
are its first significant acquisitions. Management believes the worldwide
telecommunications industry will continue to undergo a period of strong
consolidation activity due to the savings associated with larger operations.
The Combined Company intends to actively pursue those customer bases, products
and infrastructure that fit its strategy of providing high quality, state-of-
the-art telecommunications services. Except for the GlobalTel Merger and the
ITC Acquisition agreements in principle, the Combined Company has no
agreements, arrangements or understandings for any acquisitions as of the date
of this Prospectus.     
          
  Exploit Strategic Marketing Relationships and Sales Channels. In addition to
its over 170 independent sales agents, the Combined Company has access to
channels of distribution through its strategic marketing relationships.
Management expects that its relationships with IBNET and Novell will enhance
the Combined Company's ability to expand its customer base as well as
establish new relationships with independent ISPs and other network providers
in its target markets. The Combined Company believes that it can most
effectively increase its customer base and revenue by recruiting independent
sales agents. The Combined Company will be able to recruit independent sales
agents because of its advanced technology, its focus on high volume customers
and its emphasis on quality service.     
   
  Leverage Customer Base Through Enhanced Service Offerings. The Combined
Company has developed and is introducing additional telecommunications
services. To retain existing customers and attract new customers, the Combined
Company plans to increase its range of services to include enhanced voice and
data services and a suite of business grade Internet services. Most of these
services can be provided under the existing regulatory frameworks in the
Combined Company's markets. In addition, as regulatory and competitive
environments evolve and the availability of capital permits, the Combined
Company intends to migrate its call-reorigination customers, including its
enhanced service customer base, to a more cost effective call-through service.
    
       
                                      51

  Employ Flexible, Open Architecture and Proprietary Technology. By using off-
the-shelf technology that is modular, scalable and allows for the integration
of a variety of technologies, the Combined Company expects to provide its
customers with enhanced services in a timely and cost-efficient manner. The
Combined Company is committed to continue to invest in improvements in its
electronic billing, customer interface and network management systems, all of
which are critical to its delivery of services. The Combined Company also uses
proprietary call processing technologies that enable it to provide quality
telecommunications services to high volume customers. The Combined Company
intends to expand its offering of CSI's proprietary DIAL and LINK-US
transparent call processing systems and to market such systems to customers of
GlobalTel and ITC.     
   
  Increase Sales to Carriers and Resellers; Reduce Transmission Costs.
Utilizing its enhanced telecommunications infrastructure and combined carrier
transmission rates, the Combined Company intends to substantially increase its
carrier and reseller business. In expanding this business, the Combined
Company intends to leverage its extensive relationships and contacts among
telecommunications carriers and resellers. In addition to expected increases
in revenue, the related growth in transmission volume should also improve the
Combined Company's ability to negotiate preferential rates with its carriers.
The Combined Company also intends to utilize additional point-to-point private
lines, access IP and other data networks to process compressed voice and data
telecommunications traffic, and employ alternate telecommunications solutions
such as "call-through" to further reduce its overall transmission costs.     
   
  Capitalize on GlobalTel and ITC Synergies. The Combined Company anticipates
that the GlobalTel Merger and the ITC Acquisition will provide operating
synergies and efficiencies. In addition to integrating networks of independent
sales agents and infrastructure and increasing sales to carriers and
resellers, the Combined Company will seek to introduce new enhanced services
such as call-through, enhanced fax and business-grade Internet services. The
Combined Company also will have the opportunity to cross-market CSI's
proprietary DIAL and LINK-US systems to the 17,000 existing customers of
GlobalTel and ITC and to take advantage of the new business opportunities
provided by GlobalTel's strategic relationships and business grade Internet
services.     
          
SERVICES     
   
  The Combined Company seeks to address the evolving telecommunications needs
of customers located in emerging telecommunications markets. Currently, the
Combined Company offers international long-distance services, calling cards,
and enhanced voice and data services such as voice-mail, conference calling
and enhanced fax services. As changes in regulatory environments and the
availability of capital permits, the Combined Company intends to migrate its
call-reorigination customers and its enhanced service customer base to a more
cost effective call-through service.     
   
  The Combined Company believes that the growing globalization of business has
increased the mobility of business people and led to the proliferation of
multi-office enterprises, creating greater demand for convenient access to
electronic information from remote locations worldwide. As a result, the
Combined Company is designing and implementing a range of business grade
Internet services. The Combined Company expects these services to include
business quality messaging, global enhanced VPNs and other enhanced services.
GlobalTel also is designing a comprehensive "Turnkey Business ISP" solution
that incorporates all of the Combined Company's business grade Internet
services. "Turnkey Business ISP" is designed for independent ISPs and other
network providers in the Combined Company's target markets. These service
offerings are being designed to emphasize authentication, security and
notification. The following tabulates the Combined Company's current services
and services under development:

Current Services     
   
  International Call-Reorigination. The largest segment of the Combined
Company's business is call-reorigination services. Call-reorigination service
involves connecting international customers to the U.S. telephone system via
computer triggering, which makes each international customer's call originate
in the U.S. As a result, the customer's call cost structure is based on the
lower charges of the U.S. telecommunications marketplace rather than the
charges of the ITO. The Combined Company believes that the quality of the
calls made using the Combined Company's call-reorigination system is as good
as, if not better than, the quality obtained by using the ITO. The Combined
Company provides two basic types of call-reorigination: non-transparent and
transparent. To place a call using non-transparent call-reorigination, a
customer dials a unique phone number to an international carrier's switching
center and then hangs up. The customer then receives an automated call back
providing a dial tone from the United States, which enables the customer to
complete the call using U.S. telecommunications infrastructure. As of the date
of this Prospectus, approximately 89.1% of the Combined Company's customers
use non-transparent call-reorigination services. Customers who use non-
transparent call-reorigination typically are individuals or smaller businesses
that do not require the convenience and speed of transparent call-
reorigination.     
          
  Transparent call-reorigination involves the transmission of an international
call via a processor at the customer's site and one of the Combined Company's
switches in Ft. Lauderdale, Florida or Los Angeles, California. The switch
automatically connects the call to the caller's dialed destination. When
customers use the Combined Company's transparent call-reorigination service,
the call-reorigination mechanics are transparent to the customer. CSI has
developed advanced proprietary call processors called "DIAL" and "LINK-US."
When used with standard triggering methods and commercially available call
processing devices, DIAL and LINK-US provide transparent access to the
Combined Company's call-reorigination system. These systems are more expensive
than non-transparent call-reorigination systems and are typically installed in
hotels and businesses that have PBX telephone systems and require fast,
reliable, high-volume service. Less expensive systems are available for small
businesses and other customers desiring transparent call-reorigination. These
systems initiate all reorigination through global data networks, such as X.25,
Internet and frame relay, and local network digital services such as
Integrated Services Digital Networks (ISDN). The Combined Company currently
utilizes the X.25 network in Brazil and Argentina and the Internet in Brazil,
Argentina, Venezuela, South Africa and Lebanon to facilitate the call-
reorigination process. The Combined Company plans to have Internet triggering
installed in Singapore, Hong Kong and New Zealand in the near future. The
Combined Company is able to quickly adapt its call processors to virtually any
type of customer requirement, providing extremely fast and reliable service.
    
       
          
  CSI estimates that approximately 10.9% of the Combined Company's traffic is
currently routed through transparent call processors. The Combined Company has
installed approximately 200 DIAL and five LINK-US as well as approximately 200
other transparent call processors at various hotels and businesses.
Transparent call processors are proposed to be installed in several additional
hotels and businesses in Brazil, Argentina, South Africa and Hong Kong. The
Combined Company intends to focus its future sales and marketing efforts
toward recruitment of hotels and businesses that will use the Combined
Company's transparent call-reorigination service.     
   
  Carrier Reselling. The Combined Company resells its international long-
distance services to other telecommunications carriers on a wholesale basis.
The Combined Company intends to expand such services and anticipates that the
additional traffic from carrier resale customers will enable it to negotiate
more favorable rates with its carriers.     
   
  Prepaid Calling Cards. The Combined Company recently launched prepaid card
services to its customers worldwide. The Combined Company's prepaid domestic
and international calling cards may be used by customers for international
telephone calls from more than 70 countries. Calling card customers also have
access to 24-hour multi-lingual customer service and certain customization
options.     
   
  Enhanced Voice Services. The Combined Company offers enhanced voice
services, consisting of voice-mail and conference calling. Conference calling
enables customers to set up "meet me" dial-in conference calls     
 
                                      53
<PAGE>
 
   
as well as add-on conference calls, with or without operator intervention.
Conference calling has a higher margin than the Combined Company's basic voice
services. The Combined Company's services also enable customers to originate
international voice calls over the Internet by allowing call-reorigination
service to be activated from their PCs.     
   
  Hotel Operator Services and Other Hotel Services. The Combined Company plans
to introduce operator services for hotel customers. With operator services in
place, a hotel guest seeking to use a credit card to "dial around" the hotel
system is routed via the Combined Company's call-reorigination system to an
international operator. The call is billed on the guest's credit card once the
card is validated. The hotel normally would not receive any international
long-distance revenue from such "dial around" calls. In order to market and
expand its hotel operator services, the Combined Company intends to share a
percentage of its revenue from operator services with the hotel. The Combined
Company also intends to offer a variety of other services to hotel customers,
including transparent call-reorigination, facsimile, Internet access, voice-
mail and debit card services.     
          
  Facsimile Services. The Combined Company offers its customers the ability to
send high-speed international facsimiles over its network. The Combined
Company also intends to offer transmission of facsimiles via the Internet or
private data networks. The Combined Company has redundant, dedicated T-1
access to the Internet to enhance this service. The Combined Company intends
to use a portion of the proceeds of this offering to implement and expand
these services.     
   
Services Under Development     
   
  The Combined Company is developing the following new services:     
   
  Call-Through. The Combined Company will offer call-through or "direct
access" service to customers in selected markets where current regulations and
local market access charges make call-reorigination less competitive than
call-through. Call-through service involves the installation of an access
point in the local market that is connected to one of the Combined Company's
switches by a dedicated long-distance line that is leased from a carrier or
other network operator. The international customer accesses this connection to
the Combined Company's switch either by dialing a local telephone number or,
in markets where the regulatory environment permits, through an
interconnection with the ITO.     
   
  Enhanced Fax. The Combined Company's enhanced fax service, currently being
tested in Hong Kong and Mexico City, uses advanced technology to provide
customers with a higher quality and less expensive method to send facsimile
messages than conventional analog fax. Unlike conventional analog fax service,
enhanced fax service: (i) results in significantly fewer transmission errors,
particularly with international transmissions, because it is transmitted over
a digital data network; (ii) is easier to use than conventional fax, with a
feature that will retransmit the fax until it is successfully received at its
destination; and (iii) is much less expensive because it can be sent as a
digital packet in a shorter period of time. A recent study conducted by Pitney
Bowes/Gallup found that international faxes transmitted over analog phone
lines are transmitted twice on average due to interruptions and quality
problems, creating a hidden cost for users. Other features of the enhanced fax
offering include commercial-grade broadcast fax, fax on demand (or "fax
catalog") and timed delivery.     
   
  In the first half of 1998, the Combined Company plans to install an
Internet-based fax service to its fax gateway in Los Angeles, California. This
service will allow customers with Internet access to send faxes to any fax
machine worldwide and to any Internet-based e-mail address.     
   
  Business Grade Internet Services. The Combined Company is developing a suite
of enhanced services that will permit business-grade communications utilizing
Internet technologies. The Combined Company expects these business grade
Internet services to include: (i) Global Enhanced VPN, (ii) Business Quality
Messaging, (iii) Global Desktop and (iv) "Turnkey Business ISP." These
services will combine the best features of the Internet, such as openness,
easy access and low cost, with the advantages of a private network, such     
 
                                      54
<PAGE>
 
   
as high security and customized features. The Combined Company believes its
services will overcome many of the perceived inefficiencies of today's
Internet and will allow its customers to conduct business quality transactions
via the Combined Company's network infrastructure.     
   
  The Combined Company, in conjunction with Novell and other technology
providers, is developing business grade Internet services. In addition,
GlobalTel has become a Novell Business Internet Services ("BIS") partner, an
affiliation that the Combined Company believes will further enhance its
service delivery strategy and provide it access to certain key networking
technologies. Other BIS partners include AT&T, Bell Atlantic Corporation,
Nippon Telegraph and Telephone Corporation, Deutsche Telecom AG, Singapore
Telecommunications Limited Corporation and Korea Telecom. See "--Network and
Operations" and "--Sales and Marketing."     
     
    Global Enhanced VPN. The Combined Company's Global Enhanced VPN service
  enables customers to establish a wide area network among several locations
  by using the Combined Company's network infrastructure, thereby eliminating
  the cost associated with establishing and maintaining a dedicated private
  network. For example, a U.S.-based user in Hong Kong would dial a local
  number to access his or her wide area network in the United States and
  could then work on the network in the United States in accordance with the
  user's normal access privileges. The Combined Company's VPN service will be
  enhanced through the use of a commercial-grade directory infrastructure and
  certain certification and security mechanisms. Global Enhanced VPN enables
  electronic commerce by providing the user with controlled, managed and
  secure access to its VPN for customers, vendors and business partners.     
     
    Business Quality Messaging. The Combined Company's Business Quality
  Messaging ("BQM") service will enable customers to exchange messages, faxes, 
  e-mail or voice-mail in a secure and reliable manner via the Combined 
  Company's network infrastructure. BQM also will allow companies to connect
  dissimilar mail systems. These features can be customized to enable the
  Combined Company to provide different levels of service based on customer
  requirements and to price such service levels accordingly.     
     
    Global Desktop. The Global Desktop product will combine the Global
  Enhanced VPN, BQM and additional features targeting the global business
  traveler. Specifically, it will permit the user to access and exchange
  electronic information from public switched or wireless telephone networks
  worldwide.     
     
    "Turnkey Business ISP." The Combined Company believes that the great
  majority of regional ISPs need to offer additional enhanced services to
  remain competitive, but have insufficient resources to develop these
  services internally. According to an August 1997 report by Business
  Research Group, 77% of all ISPs in the United States were regional ISPs,
  83% of which lacked out-of-region access and therefore were required to
  develop their own billing and tracking systems. The Combined Company is
  designing a comprehensive turnkey service solution for regional ISPs that
  will include its business grade Internet services. This "Turnkey Business
  ISP" solution will enable regional ISPs to access the Combined Company's
  suite of enhanced services and, when available, voice-over-IP.     
          
  Completion of Services Under Development. The Combined Company has not
generated significant revenue from its enhanced services to date. The new
services described above are still under development and are not scheduled for
implementation until various times in 1998 or later. Also, the completion of
development and introduction of new services will require the investment of
significant operating capital. Of the net proceeds from this offering,
$300,000 have been allocated to the development and introduction of these new
services. It is not uncommon that the introduction of new telecommunications
services is delayed or is occasioned by technical problems.     
       
   
SALES AND MARKETING     
   
  The Combined Company's telecommunications services are marketed and sold
through a network of independent sales agents, strategic relationships and
direct marketing efforts.     
   
 Independent Sales Agents     
   
   In selling its retail services, the Combined Company employs a network of
over 170 independent sales agents that sell to customers located in over 170
countries, supplemented by direct marketing efforts. Independent     
 
                                      55
<PAGE>
 
   
sales agents are recruited through advertising in the Combined Company's
target markets and by referrals from customers and industry contacts. The
Combined Company's agreements with its independent sales agents typically are
non-exclusive and require the independent sales agents to offer the Combined
Company's services at rates prescribed by the Combined Company in accordance
with the Combined Company's policies. The Combined Company's ten largest
independent sales agents accounted for 68.6% of the Combined Company's pro
forma revenue for the 12 months ended December 31, 1997. See "Risk Factors--
Dependence on Independent Sales Agents."     
       
   
 Strategic Relationships     
   
  The Combined Company intends to leverage its strategic marketing
relationships to expand its customer base. In particular, the Combined Company
expects that its relationship with IBNET and its access to a select number of
Novell's network of over 25,000 VARs will facilitate additional contact with
many small- and medium-sized domestic business customers, foreign branch
offices of large multinational corporations and local ISPs.     
   
  IBNET     
   
  IBNET is the managing member of the Consortium for Global Commerce, which
represents thousands of individual chambers of commerce (the "Chambers") in
over 200 countries. The Consortium for Global Commerce was established to (i)
create a global intranet enabling the Chambers and their members to exchange
information and conduct business transactions electronically, and (ii) obtain
more favorable pricing and terms for certain products and services for such
members.     
   
  The Consortium's four member organizations are the International Chambers of
Commerce, the Paris Chamber of Commerce and Industry, the G77 (a non-
governmental organization comprised of 137 developing countries and China) and
IBNET, the managing partner of the Consortium. The Combined Company believes
that its relationship with the Consortium, through GlobalTel's agreement with
IBNET, will enhance its ability to establish relationships with regional ISPs
and expand its customer base in its target markets.     
   
  In April 1997, GlobalTel entered into a ten-year marketing agreement with
IBNET to provide the Chambers and their members with telecommunications
services including international voice, international fax, calling card
services, Internet services, intranet, VPN and messaging. The individual
Chambers may act as sales and marketing agents for GlobalTel's, and
ultimately, the Combined Company's services. IBNET has agreed to market
GlobalTel's services to the Chambers by promoting GlobalTel services in
Consortium literature, at Consortium trade shows and speaking engagements, and
by listing the Combined Company's services in the Consortium's databases. In
November 1997, the Consortium launched its marketing campaign to inform the
Chambers about available products and services, including GlobalTel's
services. Under its agreement with IBNET, the Combined Company also will have
the right to co-brand its services with the Chambers' trademarks, a feature
that the Combined Company believes will enhance its marketing and sales
efforts because the local chamber brand is typically well recognized and held
in high regard by local business communities. Following execution of the
agreement, Ronald P. Erickson, who will serve as Chairman of the Board of the
Combined Company, and Bruce L. Crockett and Lyman C. Hamilton, who will serve
as Directors of the Combined Company, were invited and accepted offers to
serve as Directors of IBNET.     
       
   
  Novell     
   
  In October 1997, GlobalTel entered into a three-year technology licensing
agreement with Novell that provides the Combined Company with access, and
support in marketing, to Novell's over 25,000 VARs. Novell VARs range from
small computer networking companies to large system integration firms. The
Combined Company, in conjunction with Novell, intends to create a
certification program for channel partners with respect to the Combined
Company's product offerings. In addition, GlobalTel has become a Novell BIS
partner. Other BIS partners include Deutsche Telecom AG, Bell Atlantic
Corporation, Nippon Telegraph and Telephone Corporation and Singapore
Telecommunications Limited. BIS partners have agreed upon standards for
interconnecting their respective Internet networks. The Combined Company
believes that its status as a BIS partner will allow it to benefit from any
future network connections among the BIS partners.     
 
                                      56
<PAGE>
 
       
   
Direct Sales     
   
  The Combined Company has a direct sales force of ten individuals. The direct
sales force is responsible for agent recruitment and development, retail and
wholesale sales and development of high volume corporate accounts. The
Combined Company plans to expand the existing direct sales force, which will
enable it to take advantage of its strategic marketing relationships, expand
its carrier resale business, and develop additional relationships with
regional ISPs and other network providers.     
   
  Customer Service     
   
  The Combined Company provides its customers, independent sales agents and
resellers with high-quality customer service. As of January 31, 1998, the
Combined Company employed ten customer service representatives in Seattle,
Washington and ten customer service representatives at the Combined Company's
switching facility in Ft. Lauderdale, Florida. The Combined Company intends
ultimately to concentrate its customer service functions in Ft. Lauderdale.
The customer service center operates 24 hours a day, seven days a week and
offers support in over five languages.     
       
   
CUSTOMERS     
   
  As of March 31, 1998, the Combined Company's customer base consisted of more
than 25,500 customers in over 170 countries. The Combined Company believes
that its customers prefer its service compared to the ITO's service for the
following reasons: (i) lower international, and in some cases intra-country,
telephone rates; (ii) increased system reliability and call completion rates;
(iii) improved line quality, with less echo, static and snow; and (iv)
available and responsive customer service support.     
   
  In addition to selling directly to customers, the Combined Company also
sells its reorigination service on a wholesale basis to resellers and long-
distance carriers. The Combined Company believes that long-distance services,
when sold to resellers and other carriers, are generally a commodity product
with the purchase decision based primarily on price. Although the margins on
sales to other carriers and resellers are lower than the margins on sales to
business and government customers, these sales involve lower operating
expenses and help the Combined Company optimize the use of its network and
reduce its overall carrier transmission costs. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Overview."     
   
 Business and Government Customers     
   
  The Combined Company's geographically diversified business and government
customers include: foreign offices of multinational corporations, major
international hotels and embassies and international agencies. Among these
customers are:

 Resellers     
   
  The Combined Company sells its reorgination service to resellers on a
wholesale basis. These resellers purchase service in bulk at a discounted rate
for resale to their customers. Resellers are responsible for billing their
users and for providing customer service. Resellers may sell the Combined
Company's services to their customers under their own company's name. The
Combined Company can prepare bills for resellers or resellers can prepare
their own bills based on information provided by the Combined Company.
Resellers, rather than the Combined Company, are responsible for collecting
amounts due from the customers.  See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."     
       
   
 Carriers     
   
  The Combined Company's carrier customers are long-distance companies that
purchase the Combined Company's excess international long distance capacity on
a wholesale basis for their own use. These carriers purchase service in bulk
at a discounted rate for resale to their customers. The carriers are
responsible for billing their customers and for providing customer service.
The Combined Company currently provides these services to four carrier
customers that are based in the United States.     
   
NETWORK AND OPERATIONS     
   
  The Combined Company provides its telecommunication services through its (i)
voice switching and global fax messaging infrastructure in Los Angeles,
California, and Ft. Lauderdale, Florida, (ii) access to third party
infrastructure through international telecommunications carriers and through
Equant, and (iii) enhanced fax nodes in Hong Kong and Mexico City. By using
off-the-shelf technology, which is modular and scalable and allows for the
integration of a variety of technologies, the Combined Company expects to be
able to provide its customers with enhanced services in a timely and cost-
efficient manner. The Combined Company is committed to investing in
improvements in its electronic billing, customer interface and network
management systems, which the Combined Company believes are critical to its
delivery of services. The Combined Company expects these systems to provide it
with the ability to quickly upgrade its customers from a single service to
multiple services.     
   
  International Network Switching Center--Los Angeles, California. GlobalTel's
switching center is located at One Wilshire Boulevard, Los Angeles,
California, the West Coast's principal telecommunications gateway. Most major
carriers have a switching facility at this location. In 1997, GlobalTel
upgraded its switching center to provide fiber optic access for GlobalTel to
all major carriers in the facility. As a protective measure, GlobalTel has
diversified its access to long-distance providers through contracts with
various local access providers supplying redundancy in the event of single
point failures.     
   
  At this facility GlobalTel uses two Summa Four voice switches that are
controlled by a real-time rating, billing and switching platform. This
switching platform provides enhanced voice telecommunications services and has
sufficient capacity to accommodate customer growth. GlobalTel also leases a
portion of a Northern Telecom DMS 250 tandem switch, which is connected to the
Summa Four switching platform to support GlobalTel's carrier traffic.
GlobalTel's switching center also houses a fax gateway switching platform with
e-mail to fax conversion capability and software for enhanced service
features, including fax broadcasting, fax on demand and fax mail.     
   
  International Network Switching Center--Ft. Lauderdale, Florida. ITC's
switching center is located in Ft. Lauderdale, Florida, which is
interconnected to the Miami gateway to the Latin American, African and
European telecommunications markets. The switching center consists of a
billing and provisioning system and two 1000 port class 4 tandem switches. The
switches are designed to handle international call-reorigination,
international and domestic long-distance and debit card traffic. The inbound
and outbound traffic is cross-connected to eight telecommunications carriers
via a DS3 fiber optic line. ITC uses NACT switches, billing platform and
interactive voice response ("IVR").     
       
   
  The Combined Company has recently added voice recognition, fax functions and
Internet and X.25 triggering to the switching center. These features enable
the Combined Company to offer transparent call-     
 
                                      58
<PAGE>
 
   
reorigination and call-through services, daily agent reports via the Internet
and automated credit card debiting. An additional feature under development is
customer provisioning via the World Wide Web. The Combined Company's customers
are able to access its switches in any one of 12 languages.     
   
  Redundancy. The Combined Company's operations center will be in Ft.
Lauderdale, Florida, which has redundant computer systems and fiber optics.
The Combined Company believes that redundancy gives it enhanced service
reliability, which gives it an advantage compared to many of the Combined
Company's smaller competitors that do not have redundant systems. In addition,
the Combined Company's redundant system architecture allows the flexibility to
take individual computers off line intentionally for scheduled maintenance,
upgrades and enhancements.     
   
  Fax Nodes--Hong Kong and Mexico City. GlobalTel leases and operates two fax
nodes in Hong Kong and Mexico City that are co-located in Equant's network
facilities. The nodes are serviced and maintained by Equant on a 24-hour basis
and are interconnected to local access providers. The Combined Company intends
to deploy fax nodes in additional locations during 1998.     
   
  Carriers and Network Access. The Combined Company has resale agreements with
a number of long-distance carriers in order to obtain the best available
pricing and service on certain routes. The Combined Company's enhanced fax and
business-grade Internet services will be carried through Equant's global data
network. GlobalTel's Los Angeles switching center is connected to the Equant
network center through high-speed fiber optic circuits. The Combined Company's
switching nodes have the ability to select quality and least cost routes,
depending on the quality of service desired by the customer.     
       
   
  The Combined Company relies on major telecommunications carriers including
AT&T, Sprint, WorldCom Cable & Wireless and Teleglobe to provide service to
its customers. Carrier costs constitute the largest portion of the Combined
Company's variable costs. The Combined Company has entered into contracts to
purchase capacity from various domestic and foreign carriers. Pursuant to
these contracts, the Combined Company obtains rates, which are generally more
favorable than otherwise would be available. To obtain these rates, the
Combined Company commits to purchase minute minimums from such carriers. If
the Combined Company fails to meet its minute minimums under a carrier
contract, it could still be required to pay its minimum monthly commitment as
a penalty or the contracts could be canceled. The Combined Company's aggregate
minimum monthly commitments are approximately $550,000, which represent
approximately 23.5% of the Combined Company's average monthly cost of revenue
for the 12 months ended December 31, 1997. Because of the frequent
fluctuations of long distance carriers' rates, the Combined Company believes
that it is in its best interest to have short-term carrier agreements. Most of
the Combined Company's carrier agreements will expire, or may be terminated by
either party, within one year. The Combined Company's dependence on particular
carriers will vary because the Combined Company shifts its use of carriers
depending on the rates that are offered. The Combined Company periodically
attempts to renegotiate rates with its current carriers and to establish
relationships with new long distance carriers that provide the most favorable
rates.     
       
   
  The Combined Company's ability to obtain favorable rates from the carriers
depends, in large part, on the Combined Company's total volume of long
distance traffic. The Combined Company does not believe that the loss of any
one supplier or contract would have a material adverse impact on the Combined
Company's business, financial condition or results of operations. See "Risk
Factors--Dependence on Carriers and Other Suppliers" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
    
COMPETITION
 
 General
   
  The Combined Company faces a high level of competition for customers and
independent sales agents in all of its markets, and expects competition to
intensify in the future. There are no substantial barriers to entry in the
call-reorigination industry. The Combined Company believes that there are more
than 150 companies     
 
                                      59
<PAGE>
 
   
engaged in the international call-reorigination industry. Many of the Combined
Company's competitors are significantly larger, have substantially greater
financial, technical and marketing resources, larger networks and a broader
portfolio of services than the Combined Company. Additionally, many
competitors have strong name recognition and brand loyalty, long-standing
relationships with their target customers, and economies of scale resulting in
a lower relative cost structure. There can be no assurance that the Combined
Company will be able to compete successfully against new or existing
competitors.     
   
  Inasmuch as the Combined Company believes that competition for customers and
independent sales agents is based primarily on price, transmission quality,
services offered and the ability of the supplier to "bundle" various
telecommunications services, the U.S.-based providers of international long
distance service typically set pricing, quality, service, and standards that
the Combined Company seeks to match or exceed. Increased competition could
force the Combined Company to reduce its prices and profit margins if the
Combined Company's competitors are able to procure rates or enter into service
agreements comparable to or better than those of the Combined Company, or if
competitors are able to offer other incentives to existing and potential
customers and independent sales agents. Similarly, the Combined Company has no
control over the prices set by its competitors in the long distance resale
market. The Combined Company is aware that its ability to market its long
distance resale services depends upon its ability to offer rates lower than
those of ITOs. A decrease in arbitrage spreads between U.S.-based
international calling rates and ITO rates could have a material adverse effect
on the Combined Company's business, financial condition and results of
operations.     
   
  Other potential competitors include cable television providers, wireless
telephone providers, Internet access providers, electric and other utilities
with rights of way, railways, microwave carriers and large-end users that have
private networks. The intensity of such competition has recently increased,
and the Combined Company believes that such competition will continue to
intensify as the number of new entrants increases. If the Combined Company's
competitors devote significant additional resources to the provision of
international and national long distance telecommunications services to the
Combined Company's target customer base, the Combined Company could suffer a
reduction of revenue and profits that could have a material adverse effect on
the Combined Company's business, financial condition and results of
operations.     
   
  On February 15, 1997, representatives of 69 countries, including the United
States, finalized the WTO Agreement, which addresses market access, foreign
investment and procompetitive regulatory principles for countries generating
more than 90% of worldwide telecommunications revenue. The WTO Agreement
became effective February 5, 1998. Although certain countries took specific
exceptions to the agreement, the WTO Agreement generally provides (i) market
access for United States companies to local, long distance and international
service through means of network technology on either a resale or facilities
basis, (ii) the opportunity for United States companies to hold a significant
stake in telecommunications companies in the countries that are parties to the
WTO Agreement, and (iii) the ability to take advantage of these opportunities
within a framework of pro competitive regulatory principles. The Combined
Company expects to benefit from the anticipated effects of the WTO Agreement
because of its procompetitive aspects, but it expects that it may take several
years before the principles of the agreement are implemented in many countries
and it cannot predict the extent of the opportunities that may be presented.
       
 U.S. Based Competition     
   
  Historically, the large U.S. long distance carriers have been reluctant to
compete directly with ITOs by entering the international call-reorigination
business. AT&T and others, are beginning to enter the call-reorigination
business. The Combined Company's principal U.S.-based competitors are
providers of international call-reorigination services such as AT&T, Access
Authority, IDT Corporation, International Telecom, Ltd.(Kallback), Justice
Technology Corporation, Telegroup, Inc., USA Global Link, Inc., UTG
Communications International, Inc., Viatel, Inc. and Worldpass Communications
Corp. as well as providers of traditional long distance services such as AT&T,
Cable & Wireless, Frontier Corp., GTE Communications, LCI International, Inc.,
MCI, Qwest Communications International, Inc., Sprint, WorldCom and RBOCs that
provide long distance services outside their exchange territories.     
 
                                      60
<PAGE>
 
   
 International Based Competition     
   
  The Combined Company's principal international-based competitors include,
among others, Telekom S.A. in South Africa; Telefonica de Argentina and
Telecom Argentina in Argentina; Telebras, Telesp and Telerj in Brazil; France
Telecom; PTT Telecom B.V. in the Netherlands; ACC Corp., First Telecom plc,
Oystel Communications Ltd., Swiftcall Ltd., AT&T, British Telecommunications
plc, Cable & Wireless, Mercury Communications Ltd., Sprint and WorldCom in the
United Kingdom; Deutsche Telecom AG in Germany; Optus Communications in
Australia and Kokusan Denshin, Denwa, International Telecom Japan and
International Digital Communications in Japan. The Combined Company also
competes with non-U.S. based providers of international call-reorigination
services.     
   
  The Combined Company believes that ITOs generally have certain competitive
advantages due to their control over local connectivity and their close ties
with national regulatory authorities. The Combined Company also believes that,
in certain instances, some regulators have shown a reluctance to adopt
policies and grant regulatory approvals that would result in increased
competition for the local ITO. If an ITO were to successfully pressure
national regulators to outlaw the provision of call-reorigination services,
the Combined Company could be denied regulatory approval in certain
jurisdictions in which its services would otherwise be permitted, thereby
requiring the Combined Company to seek judicial or other legal enforcement of
its right to provide services. Any delay in obtaining approval, or failure to
obtain approval, could have a material adverse effect on the Combined
Company's business, financial condition and results of operations.     
   
  ITOs may influence regulatory authorities to outlaw the provision of certain
call-reorigination services or block access to the call-reorigination services
the Combined Company markets. The ITOs generally seek to prevent call-
reorigination companies from using uncompleted local telephone calls to
trigger international calls. In such environments, the Combined Company uses
X.25 or Internet triggering to avoid violating local laws or regulations. The
Combined Company has benefited from the high differential between the rates
charged by ITOs and the rates charged by the Combined Company. As deregulation
continues in foreign markets, this differential in rates is expected to
decrease, thus placing pricing pressure on the Combined Company. Furthermore,
deregulation may lead to additional competitors entering the international
telecommunications market. If the Combined Company encounters anti-competitive
behavior in countries in which it operates (such as an ITO attempting to block
access to call-reorigination services) or if the ITO in any country in which
the Combined Company operates uses its competitive advantages to the fullest
extent, the Combined Company's business, financial condition and results of
operations could be materially adversely affected. Deregulation and increased
competition in foreign markets could cause prices for direct-dial
international calls to decrease to such a degree that customers are no longer
willing to use the Combined Company's international call-reorigination
services.     
   
TECHNOLOGY     
          
  DIAL and LINK-US Technology. CSI utilizes proprietary DIAL and LINK-US
technologies in connection with transparent call-reorigination. These
technologies are incorporated into a switch that permits transparent call-
reorigination to occur when interconnected with PBX's of hotels, large
businesses and other high volume customers. As of December 31, 1997, CSI had
installed approximately 200 DIAL systems and five LINK-US systems.     
   
  The DIAL technology, which largely consists of proprietary programming
enhancements to third-party switching equipment, is beneficially owned
entirely by CSI and is not subject to royalty payments, restrictions or
financial penalties whatsoever regarding its deployment.     
   
  CSI supports two versions of its DIAL technology. The first version is the
Enhanced DIAL system, which is installed to facilitate transparent call-
reorigination in large hotels and business parks. Enhanced DIAL utilizes a
unique combination of X.25 and Internet triggering technologies interconnected
with commercial PBX environments. The Combined Company plans to emphasize the
installation of its Enhanced DIAL system, which can support the same volume of
traffic as 64 of the Basic DIAL systems. The Combined Company's Basic DIAL
    
                                      61
<PAGE>
 
   
system is an entry-level system that is installed to facilitate transparent
call-reorigination for smaller companies. The Basic DIAL system is also
capable of utilizing X.25 and Internet triggering, but is commonly used in
locations that do not currently have X.25 or Internet access.     
   
  The LINK-US system is a PC-based automated call processing system designed
to link an internationally located PBX to the CSI switching center. Its design
includes multiple call processing redundancies to insure rapid call
completion, real time billing, and other enhanced features including voice
prompts and remote programming capability. For a description of the license
agreement relating to the LINK-US technology see "Management--Consulting
Agreement."     
          
  X.25 Triggering Technology. An X.25 data network can transport data or voice
information to any network destination in the world. CSI has proprietary
software technology that uses X.25 triggering technology in its call-
reorigination system. The Combined Company provides X.25 triggering in
Argentina and Brazil and plans to provide it in any locality where it has
several high volume customers.     
   
  In countries with underdeveloped telecommunications systems, it can be
difficult and time consuming to make an international phone call. With X.25
triggering technology up to 100% of the trigger calls to the Combined
Company's switch are transmitted out of the country and nearly 100% of the
call-reorigination calls are transmitted into the country. The combination of
X.25 triggering technology with a DIAL or LINK-US switch provides a highly
reliable telecommunications service that is especially appealing to hotels and
business owners. See "--Services."     
   
  By utilizing alternate call-triggering mechanisms, the ITO is removed from
the call-reorigination process. ITOs typically object to call-reorigination
because call-reorigination companies use the ITO's lines to trigger the call-
reorigination without paying the ITO for the use of its lines on the long
distance segment because that long distance call is not completed. When the
Combined Company uses X.25 or Internet triggering technology to trigger its
call-reoriginations, the ITO's long distance lines are not used. Instead, a
low cost, local call is completed as part of the call-reorigination triggering
process. See "Risk Factors--Risks Associated with International Operations."
       
  Internet Triggering Technology. Internet triggering is a newer technology
and is less expensive than X.25 triggering technology. CSI is currently
triggering call-reoriginations via the Internet in Brazil, Argentina,
Venezuela, South Africa and Lebanon. It intends to install Internet triggering
in Singapore, Hong Kong and New Zealand. CSI has found that call-
reoriginations using Internet triggering usually take four to six seconds and
are nearly 100% effective.     
   
INTELLECTUAL PROPERTY     
   
  GlobalTel owns U.S. Registration No. 1,944,078 for the mark PRIMECALL for
reselling long-distance telecommunications services. GlobalTel has filed
applications in the national trademark offices of Australia, Hong Kong and
Japan and in the regional European Community trademark office to register the
service mark PRIMECALL. GlobalTel filed an Intent to Use with the Patent and
Trademark Office for the mark "GLOBALTEL." There can be no assurance that the
Combined Company's trademark applications will result in any registration
being issued, or that such registration will be held valid and enforceable if
challenged. The Combined Company currently does not hold any trademark
registrations for the marks CS GLOBALTEL, GLOBALTEL, DIAL or LINK-US.     
   
  The Combined Company is aware of a pending U.S. application by Cellnet
Corporation ("Cellnet") to register the mark GLOBALTEL for providing
international wireless telephone communication services on a temporary basis.
The Combined Company believes that GlobalTel may have commenced using the mark
GLOBALTEL before Cellnet and is assessing whether to oppose Cellnet's
application. The Combined Company is also aware that Interactive Media
Technologies, Inc. is doing business in the area of international callback
services under the trade name GlobalTel. There can be no assurance that the
Combined Company's use of the     
 
                                      62
<PAGE>
 
   
mark GLOBALTEL will continue unimpeded or the Combined Company's measures to
protect its intellectual property will deter or prevent the unauthorized use
of the Combined Company's intellectual property. The Combined Company could
incur substantial costs and diversion of management resources relating to the
enforcement of its intellectual property rights. In addition, if the Combined
Company is unable to adequately protect its intellectual property, including
existing service marks and trademarks, there could be a material adverse
effect on the Combined Company's business, financial condition and results of
operations.     
   
  The Combined Company does not have an intellectual property protection
program and does not hold any patents or copyrights. It relies on trade secret
and contractual restrictions to establish and protect its technology. The
Combined Company's success depends in part on its ability to enforce
intellectual property rights for its proprietary software technology, both in
the United States and in other countries. The Combined Company's proprietary
software is protected by the use of confidentiality agreements that restrict
the unauthorized distribution of the Combined Company's proprietary
information.     
 
REGULATION
   
  The Combined Company's international call-reorigination services are subject
to the jurisdiction of many regulators. The terms and conditions under which
the Combined Company provides international communications services are
subject to government regulation. The FCC has imposed certain restrictions on
international call-reorigination providers, including the requirement that
authorized carriers provide service in a manner consistent with the laws of
the countries in which they operate. Local laws and regulations differ
significantly among the jurisdictions in which the Combined Company operates,
and the interpretation and enforcement of such laws and regulations vary.
These regulations are often based on the informal views of the local
ministries which, in some cases, are subject to influence by ITOs. In
addition, since the Combined Company's call-reorigination services effectively
bypass the local telephone system, regulators in certain countries have
objected to call-reorigination services, and 34 countries have notified the
FCC that they have declared certain call-reorigination services illegal. The
Combined Company's services in such countries comprised approximately 10.6% of
its revenue for the 12 months ended December 31, 1997. The Combined Company
generates a significant portion of its revenue from customers originating
calls in Europe, the Middle East, South Africa and South America. In the event
that countries in these regions that now permit call-reorigination prohibited
the Combined Company's services or regulated the pricing or profit levels of
such services, the Combined Company's business, financial condition and
results of operations could be materially adversely affected. At this time,
the Argentine government is attempting to provide sufficient information to
demonstrate to the FCC's satisfaction that call-reorigination is unlawful in
Argentina. Although the Combined Company believes that it is unlikely that the
FCC would rescind the Combined Company's authority to provide call-
reorigination, such action by the FCC would have a material adverse effect on
the Combined Company's business.     
   
  To facilitate the Combined Company's expansion plans, it may deploy
additional switching facilities to be located in a number of countries. As a
result, the Combined Company may be directly subject to regulation in an
increasing number of countries. In addition, there can be no assurance that
the Combined Company has accurately interpreted or will accurately predict the
interpretation of applicable laws and regulations or regulatory and
enforcement trends in a given jurisdiction, or that the Combined Company will
be found to be in compliance with all such laws and regulations. Failure to
interpret accurately the applicable laws and regulations and the mode of their
enforcement in particular jurisdictions could cause the Combined Company to
lose, or be unable to obtain, regulatory approvals necessary for it to be able
to provide certain services in such jurisdictions or to use certain of its
transmission methods. Such failure could result in significant monetary
penalties being imposed against the Combined Company. See "Risk Factors--
Regulation."     
   
  Federal regulations, regulatory actions and court decisions have had, and
may have in the future, an impact on the Combined Company and its ability to
compete. The FCC typically imposes obligations to file tariffs containing the
rate, terms and conditions of service. The FCC does not currently regulate the
Combined Company's profit levels, although the FCC has the authority to do so.
There can be no assurance that regulators     
 
                                      63
<PAGE>
 
   
will not raise material issues with regard to the Combined Company's
compliance with existing or future regulations.     
   
  The Combined Company offers service by means of call-reorigination pursuant
to an FCC authorization ("Section 214 Switched Voice Authorization") pursuant
to Section 214 of the Communications Act and certain relevant FCC decisions.
The FCC has determined that call-reorigination service using uncompleted call
signaling does not violate United States or international law, but has held
that United States companies providing such services must comply with the laws
of the countries in which they operate as a condition of such companies'
Section 214 Switched Voice Authorizations. The FCC reserves the right to
condition, modify or revoke any Section 214 Authorizations and impose fines
for violations of the Communications Act or the FCC's regulations, rules or
policies promulgated thereunder, or for violations of the clear and explicit
telecommunications laws of other countries that are unable to enforce their
laws against U.S. carriers. FCC policy provides that foreign governments that
satisfy certain conditions may request FCC assistance in enforcing their laws
against U.S. carriers. Thirty-four countries have formally notified the FCC
that certain call-reorigination services violate their laws. Only eight of
these countries have submitted copies of actual laws to the FCC that declare
certain call-reorigination services unlawful. Two of the 34 countries have
requested assistance from the FCC in enforcing their prohibitions on call-
reorigination within their respective jurisdictions. The FCC has held that it
would consider enforcement action against companies based in the United States
engaged in call-reorigination by means of uncompleted call signaling in
countries where this activity is expressly prohibited. While the Combined
Company believes that the FCC has not initiated any action to date to limit
the provisions of call-reorigination services, there can be no assurance that
it will not take action in the future. Enforcement action could include an
order to cease providing call-reorigination services in such country, the
imposition of one or more restrictions on the Combined Company, monetary fines
or, ultimately, the revocation of the Combined Company's Section 214 Switched
Voice Authorization, any of which could have a material adverse effect on the
Combined Company's business, financial condition and results of operations.
    
EMPLOYEES AND CONSULTANTS
   
  As of March 31, 1998, CSI had 18 full-time employees and two consultants;
GlobalTel had 28 full-time employees; and ITC had 18 full-time employees and
two consultants. The Combined Company plans to hire additional employees and
consultants as may be required to support expansion of the Combined Company's
operations and independent sales agent network. None of the Combined Company's
employees are covered by a collective bargaining agreement. Management
believes that the Combined Company's relationship with its employees is good.
       
PROPERTIES     
   
  CSI's executive offices are located at 8 South Nevada Avenue, Colorado
Springs, Colorado 80903. The Combined Company leases approximately 11,000
square feet of space under a lease that expires January 31, 1999 with respect
to 5,100 square feet, and December 31, 1999 with respect to the remainder. CSI
pays approximately $10,720 per month for such space. See "Certain
Transactions."     
   
  GlobalTel leases approximately 4,800 square feet of office space for its
headquarters and operations center at 1520 Eastlake Avenue East, Seattle,
Washington 98102 under a lease that expires on December 31, 1998 and requires
monthly payments of $5,850. In addition, GlobalTel leases approximately 1,500
square feet of space in Los Angeles, California, for switch equipment under a
lease that expires on June 30, 2006 and requires monthly payments of $5,040.
       
  ITC leases approximately 2,310 square feet for its executive offices at 290
Pratt Road, Meriden, Connecticut 06450 at a rate of approximately $2,380 per
month. ITC leases approximately 1,027 square feet for its switching center at
110 East Broward Boulevard, Suite 610, Ft. Lauderdale, Florida 33301 at a rate
of approximately $4,225 per month.

  In the opinion of management, each of the properties is adequately covered
by insurance and is suitable for each of such properties' current and intended
future uses. Following completion of the offering, the Combined Company
intends to evaluate and may sub-lease certain properties in order to optimize
operating efficiencies.     
   
LEGAL PROCEEDINGS     
   
  In November 1997, WorldCom commenced an action entitled "WorldCom, Inc. v.
International Telephone Company d/b/a Interglobal Telephone Company" against
ITC in Connecticut state court (Docket No. CV-970407418, Superior Court, J.D.
of New Haven) seeking damages of approximately $1.1 million for alleged past
due carrier bills. ITC believes it has meritorious defenses to the suit. ITC
intends to vigorously defend its position and will attempt to reach a
settlement with this carrier.     
   
  In addition, in the ordinary course of business, the Combined Company may
become a party to legal proceedings, the outcome of which, singly or in the
aggregate, is not expected to be material to the Combined Company's business,
financial condition and results of operations. The Combined Company intends to
aggressively pursue collection of debts, including those owed by a former
independent sales agent in Singapore.

LIMITATION OF LIABILITY AND INDEMNIFICATION
 
  CSI's Articles of Incorporation eliminate the personal liability of its
directors to CSI and its shareholders for monetary damages for breach of the
directors' fiduciary duties in certain circumstances. CSI's Bylaws provide
that CSI will indemnify its officers and directors to the fullest extent
permitted by law. In addition, CSI carries officers' and directors' liability
insurance with an annual $1 million aggregate limit. Insofar as
indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers and controlling persons of CSI pursuant to
the foregoing provisions, or otherwise, CSI has been advised that in the
opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable.

Philip A. Thomas and Sean Thomas which provide for base salaries of $115,000
and $65,000, respectively. CSI may terminate Messrs. Thomas and Thomas only
for cause (as defined in the agreements). Messrs. Thomas and Thomas have each
agreed not to compete with the Combined Company for a period of six months
following termination of the respective agreements. The Combined Company
intends to establish a cash bonus plan with an aggregate of less than $100,000
prior to completion of the offering.     
 
STOCK OPTION PLAN
   
  In 1995, the Board of Directors adopted, and the shareholders approved, an
Incentive Stock Option Plan and a Non-qualified Stock Option Plan, which in
January 1998 the shareholders approved combining into one stock option plan
(the "Stock Option Plan"). The Stock Option Plan allows for the issuance of
stock options to officers, employees, and directors, and to consultants and
advisors who render bona fide services to CSI not in connection with the
issuance of securities in a capital-raising transaction. CSI has authorized
3,000,000 shares of Common Stock for issuance upon the exercise of options
granted under the Stock Option Plan. The aggregate fair market value (measured
at the time the options are granted) of all Common Stock issued pursuant to
exercise of Incentive Stock Options under the Stock Option Plan to any one
individual to be exercisable for the first time in any one calendar year may
not exceed $100,000. The Incentive Stock Options granted under the Stock
Option Plan are intended to qualify as "Incentive Stock Options" within the
meaning of Section 422 of the Internal Revenue Code. The Non-Qualified Stock
Options granted under the Stock Option Plan are not intended to meet the
requirements of Section 422 of the Internal Revenue Code. The Stock Option
Plan is administered by the Compensation Committee. As of January 31, 1998,
Non-Qualified Stock Options to purchase up to     shares of Common Stock have
been granted under the Stock Option Plan. No Incentive Stock Options have been
granted under the Stock Option Plan.     
   
  The exercise price and period for the options granted under the plans are as
determined by the Board of Directors or committee thereof. For Incentive Stock
Options, the exercise price cannot be below the fair market value of the
underlying Common Stock at the time the options are granted, and in the case
of holders of over 10% of the combined voting power of all classes of voting
stock of CSI, the exercise price cannot be below 110% of the fair market value
of the underlying Common Stock at the time the options are granted. The
exercise period cannot exceed ten years under the Stock Option Plan. Options
may not be transferred other than by will and the laws of descent and
distribution.     
 
                                      72
<PAGE>
 
   
  The exercise of such options is subject to the satisfaction of any
applicable withholding tax or other liabilities and any listing, registration,
or qualification with any regulatory authority of the shares of Common Stock
to be issued upon exercise of such options. Unless the Common Stock issuable
upon exercise of the options has been registered with the Commission and any
applicable state regulatory authorities, each optionee represents, by
accepting such shares, that such optionee is acquiring such shares for
investment and not for resale or distribution.     
   
  The Board of Directors has reserved the right to modify or terminate the
Stock Option Plan, but may not, without the affirmative vote of a majority of
shares of capital stock then entitled to vote, do any of the following:
abolish the committee then administering the Stock Option Plan, if any, change
the qualification of its members, or withdraw the Stock Option Plan from its
supervision; make any material change to the class of persons eligible to
receive options; increase the total number of shares of Common Stock reserved
for issuance under the Stock Option Plan; increase the number of shares for
which an option is exercisable to any one employee; extend the term of the
Stock Option Plan or the maximum option periods; decrease the minimum exercise
price; or materially increase the benefits accruing to participants in the
Stock Option Plan.

                           CERTAIN TRANSACTIONS     
   
CSI     
          
  Effective September 14, 1995, Redden Dynamics, Inc. ("Redden") was merged
with and into CSI. Shareholders of Redden received a total of     shares of
Common Stock of CSI in connection with the merger. At the time of the merger,
Redden had no operations, minimal assets and no liabilities. CSI undertook the
merger in order to enable it to have a sufficient number of shareholders to
permit CSI to commence trading of its Common Stock on the OTC Bulletin Board,
which occurred effective March 18, 1996. To acquire control of Redden in order
to facilitate the merger, Robert A. Spade purchased approximately 80% of
Redden's outstanding common stock in May 1995 from certain shareholders of
Redden for $34,500. Mr. Spade was a principal shareholder, director and
President of Redden and was a principal shareholder, Chief Executive Officer,
President and Chairman of CSI prior to the merger. In the merger, Mr. Spade
exchanged the Redden shares for    shares of Common Stock. Immediately after
the merger, Mr. Spade transferred     shares of such Common Stock to 21
persons, including Mr. Nipert (    shares) and Mr. Scanlon (    shares).     
   
  CSI has received periodic advances from Robert A. Spade. In April 1996, CSI
issued an unsecured note payable to Mr. Spade in the principal amount of
$160,000, payable on May 31, 1999 and bearing interest at 10% to reflect
advances made through that date. As of January 31, 1998, the total amount of
outstanding advances from Mr. Spade under the note was $149,000.     
   
  The building in which CSI has its principal executive office is owned by a
partnership, the managing general partner of which is owned by Robert A. Spade
and his wife. CSI paid the partnership $37,592 and $87,259 in lease expense
for the fiscal years ended April 30, 1996 and 1997, respectively. Minimum
lease payments for the fiscal years ended April 30, 1998, 1999 and 2000 are
approximately $137,000, $118,000 and $55,000 reflecting the increase in leased
space from 5,100 square feet in fiscal year 1996 to 11,000 square feet
commencing September 1996. See "Business--Facilities" and the Financial
Statements.     
   
  In August 1996, CSI issued     shares of Common Stock and granted options to
purchase     shares of Common Stock at $    per share to certain minority
shareholders of WIN in exchange for their shares of WIN Common Stock. As a
result of this exchange, CSI became a shareholder of WIN. CSI then transferred
the WIN shares to WIN for certain technology and equipment owned by WIN.
Certain family members of Mr. Spade, who were shareholders of WIN, received
options to purchase     and     shares of Common Stock respectively, in the
WIN transaction. The Common Stock was valued at $    per share in the WIN
transaction. Following the WIN transaction, John Spade, who was an officer,
director and a principal shareholder of WIN, became an employee of CSI. John
Spade is the son of Robert A. Spade. Robert A. Spade was a director of WIN at
the time of the transaction and therefore this transaction may have been at
terms less favorable than one with a third party. See "Management."     
   
  In January 1997, CSI granted Dean H. Cary, a Director of CSI, options to
purchase     shares of Common Stock at $  per share in connection with
consulting services provided by Mr. Cary to CSI. The options vest 20% per year
over five years from the date of grant; provided that vesting may be
accelerated if the trading price of the Common Stock exceeds certain levels
ranging from $    to $    per share.     
   
  In October 1997, CSI incurred an obligation to pay $50,000 and in January
1998 granted options to purchase shares of Common Stock at an exercise price
of $    per share to Mr. Cary, in each case in consideration of business
consulting services.     
   
  In March and April 1998, CSI issued $320,000 aggregate principal amount of
10% Notes. For each $10,000 principal amount of 10% Notes, the holder received
warrants to purchase    shares of Common Stock at an exercise price equal to
the closing bid price on the date of the 10% Notes. Three CSI directors
invested in the notes, including: Richard F. Nipert, who was issued a $40,000
10% Note and granted     warrants; Charles A. Shields (and his wife Mary Jo
Shields), who was issued a $50,000 10% Note and granted     warrants; Dean H.
Cary, who was issued a $100,000 10% Note and granted     warrants. James L.
Williams, was also issued a $40,000 10% Note and granted     warrants.     
 
                                      76
<PAGE>
 
   
  In December 1997, Robert A. Spade and Patrick R. Scanlon each guaranteed up
to $750,000 of the amounts due on the Bridge Notes in connection with the
December 1997 Financing.     
   
  Richard F. Nipert, a Director of CSI, is a partner of the law firm of
Bright, Gibson and Nipert P.C., which from time to time has provided legal
services to CSI. Fees paid to the firm by CSI were less than 5% of the law
firm's gross revenue for each fiscal year in which they have represented CSI.
       
  Other than as set forth above, the transactions described above were on
terms that CSI's Board of Directors believed to be fair to CSI and no less
favorable to CSI than terms that could have been obtained from an unrelated
party.     
   
GLOBALTEL     
   
  In December 1995, GlobalTel acquired GFP Group. Inc. ("GFP") through the
issuance of          shares of GlobalTel common stock in a one-for-one
exchange for all of the outstanding capital stock of GFP. Pursuant to this
transaction, North Willow Family L.P., a limited partnership in which Ronald
P. Erickson, GlobalTel's Chairman, President and Chief Executive Officer, and
his two daughters are limited partners, was issued        shares of GlobalTel
common stock; and Sirius International Communications, a general partnership
in which German F. H. Burtscher, GlobalTel's Senior Vice President, Marketing
and Sales, and Frank Krentzman, a director and former Senior Vice President of
GlobalTel, were the sole partners, was issued        shares of GlobalTel
common stock. In connection with the acquisition, GlobalTel also agreed to
issue to each of Messrs. Burtscher and Krentzman         shares of GlobalTel
common stock, and to grant Mr. Erickson an option to purchase         shares
of GlobalTel common stock, all conditioned upon GlobalTel obtaining certain
financing as determined by GlobalTel's Board of Directors. Additionally,
GlobalTel assumed GFP's obligations under employment agreements with Messrs.
Erickson and Burtscher. By mutual consent of the parties, the terms of these
employment agreements were never performed.     
   
  In December 1995, as part of GlobalTel's acquisition of GFP, GlobalTel
assumed GFP's obligations under two demand promissory notes totaling $70,000
that are payable to Michael S. Brownfield, who will become a director of the
Combined Company upon completion of the GlobalTel Merger, both bearing
interest at a rate of 10% per annum, increasing to 12% per annum when the
notes are past due. Both of these notes are secured by a pledge of certain
shares of GFP stock held by GlobalTel. In connection with the assumption of
these notes, GlobalTel also issued to Mr. Brownfield a warrant to purchase for
nominal consideration         shares of GlobalTel common stock. Concurrently
therewith, GlobalTel sold to Mr. Brownfield         shares of GlobalTel common
stock for a purchase price of $     per share and granted Mr. Brownfield a
warrant to purchase        shares of GlobalTel common stock at an exercise
price of $     per share.     
   
  In November 1995, Gereg Capital Corporation ("Gereg") purchased
shares of GlobalTel common stock from GlobalTel for a purchase price of $
per share. In consideration of this purchase of GlobalTel common stock,
GlobalTel granted Gereg a warrant to purchase        shares of GlobalTel
common stock. The warrant has an exercise price of $     per share and expires
on December 29, 1998. Stephen S.V. Wong, a director of GlobalTel, is Chairman
and a controlling shareholder of Gereg.     
   
  In April 1997, GlobalTel entered into an Exclusive Services and Marketing
Agreement with IBNET. See "Business--Sales and Marketing." Pursuant to this
agreement, GlobalTel granted to IBNET a warrant to purchase        shares of
GlobalTel common stock, and will grant additional warrants if GlobalTel
reaches certain revenue targets. The warrants all have an exercise price of
$     per GlobalTel share and expire three years from the date of grant.
GlobalTel also agreed to pay IBNET certain fees based upon a percentage of
GlobalTel's gross margin for services purchased by customers referred to
GlobalTel by IBNET. In return, IBNET agreed to issue to GlobalTel 100,000
shares of common stock of IBNET. Bruce L. Crockett, Ronald P. Erickson and
Lyman C. Hamilton are directors of IBNET, and each holds options to purchase
50,000 shares of IBNET's common stock. In addition, Mr. Hamilton owns 100,000
shares of IBNET's common stock (or approximately 2% of IBNET's total
outstanding common stock).

Description of Indebtedness." The following table describes promissory notes
issued by GlobalTel to persons who will become directors or executive officers

  In November 1997, Stephen S.V. Wong loaned GlobalTel $25,000 pursuant to a
promissory note bearing interest at a rate of 10% per annum, increasing to 15%
after default. This note was repaid in full in December 1997.     
   
  Other than as set forth above, the transactions described above were on
terms that GlobalTel's Board of Directors believed to be fair to GlobalTel and
no less favorable to GlobalTel than terms that could have been obtained from
an unrelated party.     
   
ITC     
   
   In August 1997, CSI entered into a Reciprocal Telecommunications Agreement
with ITC. In April 1998, CSI entered into an agreement with ITC and its
shareholders, Lynch Family, LLC, Sean Thomas and Philip Thomas by which CSI
will purchase all of the outstanding common stock of ITC from its
shareholders. Upon consummation of this offering and the ITC Acquisition,
Lynch Family, LLC and Messrs. Thomas and Thomas will receive an aggregate of
$3.3 million in cash and     shares of Common Stock based on an assumed
initial offering price of $    per share to be issued on the first anniversary
of the closing of this offering. Furthermore, John Lynch, the manager of Lynch
Family, LLC, will enter into a one year consulting agreement with the Combined
Company under which he will receive $125,000, and Philip Thomas and Sean
Thomas will enter into one year employment agreements with the Combined
Company under which they will receive annual salaries of $115,000 and $65,000,
respectively. See "Management."     
          
  In December 1997, CSI paid $178,000 to ITC in consideration of consulting
services provided by ITC in negotiating an agreement with a carrier on behalf
of CSI.     
          
  The Combined Company has adopted a policy that future transactions between
the Combined Company and its officers, directors and 5% or more shareholders
are subject to approval by a majority of the disinterested directors of the
Combined Company. Any such transactions will be on terms believed to be no
less favorable than could be obtained from unaffiliated parties.     
 
TRANSACTIONS WITH PROMOTERS
   
  CSI believes that Messrs. Robert A. Spade and James L. Williams may be
considered "founders" or "promoters" of CSI. In addition to the transactions
referenced in "Certain Transactions," Mr. Spade purchased     shares of Common
Stock from CSI at various times from April 1993 to December 1994 at prices
ranging from $    per share to $    per share.     
 
                                      79
<PAGE>
 
   
  Mr. Williams purchased     shares of Common Stock from CSI at various times
from April 1993 to June 1995 at prices ranging from $    to $    per share.
Mr. Williams also acquired     shares from Mr. Spade at various times from
August 1993 to December 1994. Mr. Williams has received approximately $38,400
from CSI as compensation for services in connection with equity and debt
financings by CSI. In addition, Mr. Williams loaned $40,000 to CSI and
received a 10% convertible note in October 1996 that he converted into shares
of Common Stock in January 1997. In connection with the note, Mr. Williams
received warrants to purchase     shares of Common Stock at $    per share. In
June 1997, Mr. Williams purchased an additional 10% convertible note with a
$20,000 principal amount. In connection therewith, he received a warrant to
purchase     shares of Common Stock at an exercise price of $    per share. In
October 1997, Mr. Williams purchased     shares of Common Stock for $    per
share in a private placement. In March 1998, Mr. Williams loaned $40,000 to
CSI and received a note bearing interest at 10% per annum.     
   
  CSI used the proceeds from the sales of Common Stock discussed above to fund
its operations. CSI believes that these transactions were conducted on terms
that were fair and reasonable to CSI and at prices that approximated the fair
market value of the Common Stock at the time of the transactions. See
"Principal Shareholders."

<PAGE>
 
                           DESCRIPTION OF SECURITIES
   
  The authorized capital stock of CSI consists of 25,000,000 shares of Common
Stock, no par value per share, and 5,000,000 shares of Preferred Stock, no par
value per share.     
   
COMMON STOCK     
   
  Upon consummation of the offering,     shares of Common Stock will be issued
and outstanding (assuming no options are exercised after March 31, 1998, and
assuming the Underwriters' over-allotment option is not exercised). If the
over-allotment option is exercised in full,     shares of Common Stock will be
issued and outstanding.     
   
  Holders of Common Stock are each entitled to cast one vote for each share
held of record on all matters presented to shareholders. Cumulative voting is
not allowed; hence, the holders of a majority of the outstanding Common Stock
can elect all directors. Holders of Common Stock are entitled to receive such
dividends as may be declared by the Board of Directors out of funds legally
available therefor and, in the event of liquidation, to share pro rata in any
distribution of CSI's assets after payment of liabilities. The Board of
Directors is not obligated to declare a dividend and it is not anticipated
that dividends will be paid in the foreseeable future. See "Dividend Policy."
Holders of Common Stock do not have preemptive rights to subscribe to
additional shares if issued by CSI. Except for     shares which were purchased
with a note, which is outstanding, all of the outstanding shares of Common
Stock are fully paid and non-assessable and all of the shares of Common Stock
offered hereby will be, upon issuance, fully paid and non-assessable.     
 
PREFERRED STOCK
   
  The Board of Directors has the authority, without further shareholder
approval, to issue up to 5,000,000 shares of Preferred Stock from time to time
in one or more series, to establish the number of shares to be included in
each such series, and to fix the designation, powers, preferences and rights
of the shares of each such series and the qualifications, limitations or
restrictions thereof. The issuance of Preferred Stock may have the effect of
delaying or preventing a change in control of CSI. The issuance of Preferred
Stock could decrease the amount of earnings and assets available for
distribution to the holders of Common Stock or could adversely affect the
rights and powers, including voting rights, of the holders of the Common
Stock. In certain circumstances, such issuances could have the effect of
decreasing the market price of the Common Stock. As of the closing of this
offering, no shares of Preferred Stock will be outstanding and CSI currently
has no plans to issue any shares of Preferred Stock.     
 
DESCRIPTION OF INDEBTEDNESS
   
  Mandatorily Redeemable Convertible Promissory Notes. In December 1997, CSI
issued Bridge Notes in an aggregate principal amount of $2.8 million. Interest
on the Bridge Notes is payable at a rate of 10% per annum, semi-annually. The
aggregate outstanding principal amount of the Bridge Notes is due five days
following the closing of this offering. Robert A. Spade, the Chairman and
Chief Executive Officer of CSI, and Patrick R. Scanlon, the President and
Chief Operating Officer of CSI, each guaranteed payment of the Bridge Notes
for up to $750,000. For each $100,000 of principal amount of the Bridge Notes,
the holder will receive    Bridge Shares upon the closing of this offering,
based on a $   per share initial offering price. Such Bridge Shares are
offered by this Registration Statement.     
   
  10% Notes. From October 1996 through July 1997, CSI issued unsecured
convertible promissory notes (the "10% Notes") in an aggregate principal
amount of $415,000. Interest on the 10% Notes is payable at a rate of 10% per
annum, semi-annually, commencing on March 31, 1997 and continuing until the
maturity date, which is two years from the respective dates of investment. The
aggregate outstanding principal amount of the 10% Notes is due on the maturity
date. The 10% Notes may be converted into shares of Common Stock at a
conversion price of 90% of the average high bid and low asked price of the
Common Stock on the day before     
 
                                      81
<PAGE>
 
   
conversion. CSI may prepay any of the 10% Notes in full at any time without
penalty, and any note holders may cause CSI to repay such holder's note at the
end of each six-month period that any principal is outstanding upon 30 days
written notice. As of January 31, 1998, $385,000 principal amount of 10% Notes
have been converted. For each $10,000 of principal amount of the 10% Notes,
the holder received warrants to purchase    shares of Common Stock of CSI at
an exercise price equal to the closing bid price of the Common Stock on the
date of the 10% Notes.     
   
  15% Notes. From February 1997 through March 1997, CSI issued $85,000
aggregate principal amount of the 15% Notes. Interest on the 15% Notes, and
the aggregate outstanding principal amount of the 15% Notes, are payable on
the maturity date, which is six months after the date of each Note. For each
$10,000 of principal amount of 15% Notes, the holder received warrants to
purchase    shares of Common Stock at an exercise price equal to the closing
bid price of the Common Stock on the date of the 15% Notes. In March 1998, the
note holders agreed to extend their notes until various times between June
1998 and September 1998.     
   
  GlobalTel Convertible Notes. As of January 31, 1998, promissory notes issued
by GlobalTel in the aggregate principal amount of $2.7 million convertible
into an aggregate of approximately     shares of GlobalTel common stock were
outstanding. The notes generally bear interest at a rate of 10% per annum, are
for a term of 12 or 18 months and are convertible into GlobalTel common stock
under certain circumstances.     
   
  GlobalTel Full Coverage Notes. Promissory notes issued by GlobalTel in
November and December 1997 (the "GlobalTel Full Coverage Notes") in the
aggregate principal amount of $3.0 million are outstanding. These notes bear
interest at a rate of 10% per annum, increasing to 15% after default, and are
due upon the closing of this offering. In addition to repayment of principal
and interest, note holders will receive a total of    shares of Common Stock
upon the closing of the GlobalTel Merger. If the offering is not completed by
July 1, 1998, noteholders have the right to receive warrants to purchase
shares of common stock equal to the principal amount of the note divided by
$   , in lieu of the shares of common stock to be issuable upon closing of the
GlobalTel Merger, warrants equal to the principal amount of the note divided
by $   . These warrants will have an exercise price of $    per share and will
expire three years from the date of grant.     
 
REGISTRATION RIGHTS
   
  CSI has agreed to grant to two holders of    shares of the Common Stock (the
"Rights Holders") certain "piggy-back" registration rights under the
Securities Act with respect to such shares. Under the terms of agreements
between CSI and these Rights Holders, if CSI proposes to register any of its
Common Stock under the Securities Act for its own account or for the account
of other security holders (other than pursuant to this offering and certain
excluded registration forms), the Rights Holders are entitled to notice of
such registration and to include in such registration shares of Common Stock
that they hold, subject to cutback limitations that may be imposed by the
underwriter of any underwritten public offering of the Common Stock. The
Rights Holders are not required to bear any expenses incurred by CSI in
connection with registering the Rights Holders' shares, but underwriting fees,
discounts, or commissions relating to the sale of each Rights Holder's shares
are borne by the applicable Rights Holder. CSI is not required to include any
of the shares with registration rights in a registration if the holders of
such shares would be able to sell such shares without registration pursuant to
Rule 144 of the Securities Act or otherwise. None of the Rights Holders will
participate in this offering.     
   
  CSI has agreed to grant to Lynch Family, LLC, Philip Thomas and Sean Thomas
(collectively, the "Former ITC Shareholders") certain "demand" registration
rights under the Securities Act with respect to the Common Stock (the "ITC
Acquisition Stock") they will receive in connection with the ITC Acquisition.
Under the terms of the Stock Purchase Agreement, CSI is obligated, after the
first anniversary of the completion of the ITC Acquisition, upon the demand of
the Former ITC Shareholders, to file within 30 days of such demand (subject to
    
                                      82
<PAGE>
 
   
an extension in the event CSI is then involved in certain transactions not in
the ordinary course of business) a registration statement on Form S-3 covering
the ITC Acquisition Stock. The Former ITC Shareholders are not required to
bear any expenses incurred by CSI in connection with registering the ITC
Acquisition Stock.     
       
   
  Following the closing of the GlobalTel Merger, the holders of approximately
   shares of outstanding Common Stock and Common Stock issued upon conversion
or exercise of certain of GlobalTel's outstanding securities will be entitled
to certain rights with respect to the registration of such shares under the
Securities Act.     
       
TRANSFER AGENT
   
  The transfer agent and registrar for CSI's Common Stock is American
Securities Transfer & Trust, Inc.     
 
                               RESCISSION OFFER
   
  Immediately after the closing of this offering, the Combined Company intends
to commence the Rescission Offer in accordance with the federal securities
laws and the Washington Securities Act with respect to the following
securities which were issued or sold by GlobalTel from 1995 through 1997 to
approximately 40 individuals and entities who GlobalTel believes at the time
of purchase were residents of the State of Washington:     
   
(i)   an aggregate of    shares of Common Stock, of which    and    shares were
      issued at $   and $   per share, respectively (the "Cash Rescission
      Stock");     
   
(ii)  an aggregate of    shares of Common Stock (the "1995 Rescission Stock")
      which were issued to one individual at $   per share, together with a
      warrant to purchase approximately    shares of Common Stock;     
       
   
(iii) an aggregate of    shares of Common Stock (the "Converted Note
      Rescission Stock") issued upon conversion of promissory notes, together
      with warrants to purchase an aggregate of approximately    shares of
      Common Stock delivered in conjunction with the issuance of such
      promissory notes;     
   
(iv)  $350,000 in aggregate principal amount of promissory notes (the
      "Rescission Notes"), together with warrants to purchase an aggregate of
      approximately    shares of Common Stock; and     
   
(v)   an aggregate of    shares of Common Stock (the "Converted Warrants
      Rescission Stock") to be issued upon the closing of this offering upon
      conversion of certain warrants (the "Converted Warrants").     
   
  The Converted Warrants were originally issued to certain individuals in
conjunction with promissory notes that were subsequently converted (together
with accrued interest thereon) into shares of Converted Note Rescission Stock.
The Cash Rescission Stock, 1995 Rescission Stock, Converted Note Rescission
Stock and Converted Warrants Rescission Stock are hereinafter collectively
referred to as the "Rescission Stock." The Converted Warrants, together with
the warrants delivered in connection with the 1995 Rescission Stock, Converted
Note Rescission Stock and Rescission Notes are hereinafter collectively
referred to as the "Rescission Warrants." The Rescission Notes, the Rescission
Stock and the Rescission Warrants are hereinafter collectively referred to as
the "Rescission Securities." Following this offering the Combined Company
intends to refile a registration statement previously filed by GlobalTel
relating to the Rescission Offer.     
   
  The Combined Company believes that the Rescission Securities may have been
issued or sold in violation of the registration requirements of the Washington
Securities Act. As a precaution against potential claims by holders of
Rescission Securities, and without admitting non-compliance with the
Washington Securities Act, the Combined Company plans to offer to rescind such
prior issuances and sales by offering to repurchase the Rescission Securities
at the price paid therefor plus interest at the statutory rate of 8% per annum
from the date of purchase to the expiration of the Rescission Offer. The price
paid will be based upon the price paid for the original security purchased by
the purchaser from GlobalTel, regardless of the type of Rescission Security
currently held by the purchaser. The price paid for the Cash Rescission Stock
is $   per share with respect to    shares and $   per share with respect to
   shares, for an aggregate price of $1.0 million. The price     
 
                                      83
<PAGE>
 
   
paid for the 1995 Rescission Stock is $    per share for an aggregate price of
approximately $500,000. The price paid for the Converted Note Rescission Stock
is equal to the principal amount of the original promissory notes related
thereto for an aggregate price of $791,000. The aggregate price paid for the
Rescission Notes is $350,000. There is no separate price for the Converted
Warrants Rescission Stock because by the terms and conditions of the
Rescission Offer, the Converted Warrants Rescission Stock must be surrendered
if the holder of the related Converted Note Rescission Stock elects to accept
the Rescission Offer with respect to its Converted Note Rescission Stock. The
aggregate accrued interest with respect to all of the Rescission Securities as
of June 30, 1998 will be approximately $397,000. If all holders of Rescission
Securities were to accept the Rescission Offer, the Combined Company would be
required to make payments aggregating approximately $3.2 million, plus the
aggregate amount of any additional interest thereon that accrues after June
30, 1998. The Rescission Offer will expire 15 days after the offer is
transmitted. The Combined Company currently expects to use a portion of the
proceeds from this offering to make payments under the Rescission Offer, if
any are required. Offerees who do not accept the Rescission Offer will
thereafter hold registered Rescission Securities under the Securities Act
which, in the case of the Rescission Stock, will be freely tradeable by non-
affiliates in the public market as of the effective date of the Rescission
Offer Registration Statement.     
   
  As of the date hereof, management is not aware of any claims for rescission
against GlobalTel or the Combined Company. Also, current and former officers
and directors of GlobalTel holding an aggregate of $1.4 million (including
statutory interest accrued thereon as of February 28, 1998) of the Rescission
Securities have indicated their intent not to accept the Rescission Offer,
although no formal Rescission Offer has been made to them and they have not
and may not agree to reject the Rescission Offer until the Rescission Offer
Registration Statement has been declared effective by the Securities and
Exchange Commission and the Rescission Offer has commenced. There can be no
assurance that all or a substantial portion of the Rescission Securities will
not be tendered in response to the Rescission Offer. Use of a portion of the
proceeds of this offering in connection with the Rescission Offer will reduce
the amount of working capital available to the Combined Company and may
require it to seek additional capital sooner than otherwise might be required.
The Rescission Offer is being made in order to limit, so far as may be
permitted under applicable federal and state securities laws, the potential
liability of the Combined Company with respect to the offer and sale of the
Rescission Securities. Although the Combined Company believes that the offer
and sale of the Rescission Securities were made in compliance with the
registration requirements of federal securities laws, if a holder of the
Rescission Securities were to assert a claim that the Rescission Securities
were sold in violation thereof, the position of the Securities and Exchange
Commission is that liabilities under the federal securities laws are not
terminated by making a rescission offer. Furthermore, notwithstanding the
Rescission Offer, there can be no assurance that the Combined Company will not
be subject to penalties or fines relating to past securities issuances or that
other holders of the Combined Company's securities will not assert or prevail
in claims against the Combined Company for rescission or damages under state
or federal securities laws.

<PAGE>
 
                        SHARES ELIGIBLE FOR FUTURE SALE
   
  Upon completion of this offering, CSI will have    shares of Common Stock
outstanding, assuming no options are exercised after March 31, 1998 and
assuming the Underwriters' over-allotment option is not exercised. If the
Underwriters' over-allotment option is exercised in full,    shares of Common
Stock will be outstanding. Of these shares, the    shares sold in this
offering (and any shares sold by CSI upon exercise of the Underwriters' over-
allotment option) will be freely transferable by persons other than
"affiliates" of CSI (as that term is defined under the Securities Act) without
restriction or further registration under the Securities Act.     
   
  The remaining    outstanding shares of Common Stock are "restricted
securities" within the meaning of Rule 144 under the Securities Act and may
not be sold in the absence of registration under the Securities Act unless an
exemption from registration is available, including the exemption contained in
Rule 144. All of such shares are eligible for sale under Rule 144 commencing
on or after 90 days from the date of this Prospectus. Pursuant to the terms of
the Underwriting Agreement, the Representative has required that the Common
Stock owned by officers, directors and holders of 2% or greater of the Common
Stock may not be sold until 12 months (180 days with respect to the Selling
Securityholders' Shares) from the date of this Prospectus without the prior
written consent of the Representative.     
   
  In general, under Rule 144 as currently in effect, a shareholder who has
beneficially owned shares for at least one year is entitled to sell, within
any three-month period, a number of "restricted" shares that does not exceed
the greater of 1% of the then outstanding shares of Common Stock or the
average weekly trading volume during the four calendar weeks preceding such
sale. Sales under Rule 144 are also subject to certain manner of sale
limitations, notice requirements and the availability of current public
information about CSI. Rule 144(k) provides that a shareholder who is not
deemed to be an "affiliate" and who has beneficially owned shares for at least
two years is entitled to sell such shares at any time under Rule 144(k)
without regard to the limitations described above.     
   
  In addition to the shares of Common Stock that are currently outstanding, a
total of     shares of Common Stock have been reserved for issuance upon
exercise of options granted under the Option Plan, under which options to
acquire     shares of Common Stock have been granted. Shares purchased
pursuant to options will be freely tradeable without restriction under the
Securities Act, except for shares held by an "affiliate" of the Combined
Company, which shares will remain subject to certain restrictions. See
"Management--Stock Option Plan."     
          
  The Combined Company is unable to estimate the number of shares that may be
sold in the future by the existing shareholders or holders of options or the
effect, if any, that sales of shares by the existing shareholders or option
holders will have on the market price of the Common Stock prevailing from time
to time. Sales of substantial amounts of Common Stock by the existing
shareholders or holders of options could adversely affect then prevailing
market prices.

  The Underwriting Agreement provides that the Underwriters' obligations are
subject to certain conditions precedent and that the Underwriters are
committed to purchase all shares of Common Stock offered hereby (other than
those covered by the over-allotment option described below) if the
Underwriters purchase any shares.     
   
  The Representatives have advised CSI that the several Underwriters propose
to offer the shares of Common Stock in part directly to the public at the
price to public set forth on the cover page of this Prospectus, and in part to
certain dealers at the price to public less a concession not exceeding $
per share. The Underwriters may allow, and such dealers may reallow, a
concession not exceeding $     per share to other dealers. After the shares of
Common Stock are released for sale to the public, the Representatives may
change the initial price to public and other selling terms. No change in such
terms shall change the amount of proceeds to be received by CSI as set forth
on the cover page of this Prospectus. The Representatives will also receive a
nonaccountable expense allowance equal to 2.5% of the gross proceeds of the
offering including the over-allotment option, if exercised, of which $75,000
has been paid.     
   
  CSI has granted the Underwriters an option, exercisable for 45 days after
the date of this Prospectus, to purchase up to     additional shares of Common
Stock at the initial price to public. The Underwriters may purchase these
shares solely to cover over-allotments, if any, in connection with the sale of
the shares of Common Stock offered hereby. If the Underwriters exercise the
over-allotment option, the Underwriters will purchase additional shares in
approximately the same proportions as those in the above table.     
   
  The Representatives have informed CSI that it does not expect any sales of
the shares of Common Stock offered hereby to be made to discretionary accounts
by the Underwriters.     
   
  The Underwriting Agreement provides that CSI and the Underwriters will
indemnify each other against certain liabilities under the Securities Act.
    
          
  The Underwriters may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation
M under the Exchange Act. Over-allotment involves syndicate sales in excess of
the offering size, which creates a syndicate short position. Stabilizing
transactions permit bids to purchase the underlying security so long as the
stabilizing bids do not exceed a specified maximum. Syndicate     
 
                                      86
<PAGE>
 
   
covering transactions involve purchases of the securities in the open market
after the distribution has been completed in order to cover syndicate short
positions. Penalty bids permit the Underwriters to reclaim a selling
concession from a syndicate member when the securities originally sold by such
syndicate member are purchased in a syndicate covering transaction to cover
syndicate short positions. Such stabilizing transactions, syndicate covering
transactions and penalty bids may cause the price of the Common Stock to be
higher than it would otherwise be in the absence of such transactions.     
   
  Neither CSI nor the Underwriters makes any representation or prediction as
to the direction or magnitude of any effect that the transactions described
above may have on the price of the Common Stock. In addition, neither the
Company nor any of the Underwriters makes any representation that the
Underwriters will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.     
   
  CSI's officers and directors, holding in the aggregate    shares of Common
Stock, have agreed not to offer, sell or otherwise dispose of any shares of
Common Stock for a period of 12 months after the date of this Prospectus
without the prior written consent of the Representatives.     
   
  CSI has also agreed to sell to the Representatives, for nominal
consideration, warrants (the "Representatives' Warrants") to purchase
shares of Common Stock. The Representatives' Warrants will be exercisable, at
a price per share equal to 120% of the initial price to public, commencing one
year from the date hereof and for a period of four years thereafter. During
the exercise period, holders of the Representatives' Warrants are entitled to
certain demand and incidental registration rights with respect to the
securities issuable upon exercise of the Representatives' Warrants. The Common
Stock issuable upon exercise of the Representatives' Warrants is subject to
adjustment in certain events to prevent dilution. The Representatives'
Warrants cannot be transferred, assigned or hypothecated for a period of one
year from the date of issuance except to Underwriters, selling group members
and their officers or partners.     
   
  Cruttenden Roth Incorporated ("Cruttenden Roth"), one of the
Representatives, provided GlobalTel with consulting, advisory and valuation
services throughout 1997 and agreed to continue to provide such services
throughout 1998 for a fee of $125,000. The fee is represented by a promissory
note due on the earlier of completion of this offering or July 1, 1999. The
note bears interest at the rate of 7% per annum. Following the completion of
the GlobalTel Merger, Cruttenden Roth will provide consulting, advisory and
valuation services to the Combined Company pursuant to the prior understanding
with GlobalTel.     
   
  In January 1998, GlobalTel entered into a letter agreement with Cruttenden
Roth (as amended, the "Letter Agreement") pursuant to which Cruttenden Roth
agreed to perform various investment banking services. The Letter Agreement
provides that, upon a change in control of GlobalTel, Cruttenden Roth will
receive a transaction fee equal to 5% of the consideration received by
GlobalTel or its shareholders (the "Transaction Fee"). Consideration is
defined by the Letter Agreement to include the cash or securities received,
the face amount of debt assumed by a purchaser, change of control compensation
and any distributions in contemplation of the change of control. Cruttenden
Roth will receive a Transaction Fee equal to $    on consummation of the
GlobalTel Merger. Other than $10,000 received as an advance, Cruttenden Roth
has not received any payments under the Letter Agreement.     
   
  The Common Stock is traded infrequently in limited quantities on the OTC
Bulletin Board under the symbol CSYG. The public offering price of the Common
Stock has been determined by arms-length negotiation between CSI and the
Representatives. There is no direct relation between the offering price of the
Common Stock and the assets, book value or net worth of CSI. Among the factors
considered by CSI and the Representatives in pricing the Common Stock were the
results of operations, the current financial condition and future prospects of
the Combined Company, the experience of management, the amount of ownership to
be retained by the existing shareholders, the general condition of the economy
and the securities markets, and the demand for securities of companies
considered comparable to CSI.

  call-reorigination (or "call-back")--A form of dial-up access that allows a
user to access a telecommunications company's network by placing a telephone
call, hanging up, and waiting for an automated callback. The callback then
provides the user with dial tone which enables the user to initiate and
complete a call.     
   
  call-through--The provision of international long distance service through
the conventional long distance network or via an in-country switch allowing
the customer direct access to a long distance carrier's network without the

network equipment at the facility of another telecommunications provider.     
 
  dedicated or direct access--A means of accessing a network through the use
of a permanent point-to-point circuit typically leased from a facilities-based
carrier. The advantage of dedicated access is simplified premises-to-anywhere
calling, faster call set-up times and potentially lower access and

carrier networks that offer the lowest rates.
   
  node--A specially configured piece of telecommunications equipment which
provides the interface between the local ITO where the node is located and the
Combined Company's gateway switch. A node collects and concentrates call
traffic from its local area and transfers it to Combined Company's switch via

locations.
 
  resale--Resale by a provider of telecommunications services of services sold

            PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS     
                                  
                               (UNAUDITED)     
   
  The following unaudited pro forma condensed combined financial statements of
Communications Systems International, Inc. (CSI) have been prepared to give
effect to the completion of the proposed public offering (the Offering) and
the proposed acquisitions of GlobalTel Resources, Inc. (GlobalTel) (the
Merger) and International Telephone Company (ITC) (the Acquisition), described
below.     
       
   
  CSI has entered into a letter of intent with GlobalTel pursuant to which
GlobalTel will merge with CSI and CSI will issue shares of its Common Stock
for all outstanding shares of GlobalTel's preferred and common stock. The pro
forma condensed combined balance sheet as of December 31, 1997 assumes the
Merger was consummated on December 31, 1997. The pro forma condensed combined
statement of operations for the year ended December 31, 1997 assumes the
Merger was consummated on January 1, 1997.     
   
  CSI has entered into an agreement to acquire all of the stock of ITC for
$3,300,000 cash and the issuance of shares of CSI's Common Stock valued at
$2,070,000. The number of shares to be issued by CSI will be based on the
public offering per share price. The pro forma condensed balance sheet as of
December 31, 1997 assumes the Acquisition was consummated on December 31,
1997. The pro forma condensed combined statement of operations for the year
ended December 31, 1997 assumes the Acquisition was consummated on January 1,
1997.     
   
  In management's opinion, all material adjustments necessary to reflect the
transactions are presented in the pro forma adjustments as of and for the year
ended December 31, 1997 which are based upon available information and the
currently agreed upon terms of the Merger and Acquisition. The financial
statements of ITC as of and for the twelve months ended December 31, 1997 are
unaudited and are not derived from the audited financial statements of ITC as
of and for the ten months ended October 31, 1997. The pro forma condensed
combined financial statements do not purport to present CSI's financial
position or results of operations that would have occurred had the
transactions, to which pro forma effect is given, been consummated as of the
dates or for the periods indicated and do not purport to project CSI's
financial position or results of operations at any future date or for any
future period, and should be read in conjunction with the separate financial
statements of CSI, GlobalTel, and ITC.

                               (UNAUDITED)     
   
  The following pro forma adjustments give effect to (i) the completion of the
GlobalTel Merger, the ITC Acquisition and the Offering as of December 31, 1997
for the balance sheet and (ii) the Merger, the Acquisition and the Offering as
of January 1, 1997 for the statement of operations:     
 
PURCHASE ADJUSTMENTS
     
  (a) Reflects the proposed acquisition of GlobalTel through the issuance of
          shares of CSI's Common Stock for all the outstanding preferred and
      common stock of GlobalTel, including GlobalTel's common stock subject
      to rescission. The CSI Common Stock to be issued to GlobalTel's common
      shareholders has been valued at an assumed public offering price of
      $    per share, discounted by 30% due to trading restrictions and other
      limitations on their transferability. The number of CSI's common shares
      to be issued to GlobalTel's preferred shareholders has been determined
      based on the liquidation value of such preferred shares. Adjustments
      made to GlobalTel's assets and liabilities are based on estimates of
      their fair values.     
     
  (b) Reflects the increase in amortization expense due to the amortization
      of the intangible assets and the write-off of in-process research and
      development recorded in the acquisition of GlobalTel. Such intangible
      asset amortization assumes the following useful lives: distribution
      channels and customer lists--2 to 3 years; intellectual property and
      license agreement--5 to 7 years; goodwill--5 years. A deferred income
      tax benefit, resulting from the generation of net operating losses
      subsequent to the GlobalTel Merger and from the decreasing differences
      between the book and tax bases of intangible assets, is recognized to
      eliminate the deferred income tax liability. Interest expense, which
      includes the amortization of debt issuance costs and debt discounts,
      has been reduced as a result of the adjustment of GlobalTel's debt to
      its fair value at the date of the Merger.     
     
  (c) Reflects the proposed acquisition of ITC for $5,370,000 based on
      currently agreed upon terms which include: cash payments of $1,750,000
      (excluding deposits of $225,000 made prior to December 31, 1997) due to
      the ITC shareholders at the completion of the Offering; the commitment
      to issue an estimated number of CSI Common Stock valued at $1,250,900
      to the ITC shareholders, which value is based on the public offering
      price and discounted by 30% as a result of the timing of the issuance
      of such stock and the limitations on its transferability; accrual of an
      estimated payment to the ITC shareholders of $873,000; reclassification
      of deposits given to ITC of $225,000; and the elimination of ITC's
      historical equity balances in connection with purchase accounting. The
      recorded values of ITC's assets and liabilities are believed to be
      reasonable estimates of their fair values. The number of shares to be
      issued to, and the amount of cash to be paid from escrow to, ITC
      shareholders, is ultimately dependent upon the resolution of certain
      ITC liabilities; the acquisition cost, however, is not expected to be
      affected.     
     
  (d) Reflects the increase in amortization expense due to the amortization
      of the distribution channels and customer lists recorded in the
      acquisition of ITC which are amortized over a three-year period.     
 
  (e) Reflects the elimination of intercompany transactions and balances
      between CSI and ITC.
       
RECAPITALIZATION ADJUSTMENT
     
  (f) Reflects the issuance of the CSI Common Stock valued at $795,200 to the
      holders of the bridge debt issued by CSI in December 1997. Such amount
      is the estimated value of the equity features of the debt.

                               (UNAUDITED)     
 
OFFERING ADJUSTMENTS
     
  (g) Reflects the estimated net proceeds of the Offering of $25,617,719, of
      which $1,325,000 is to be placed in escrow to satisfy the terms of the
      ITC acquisition agreement. Reflects deferred offering costs of $117,719
      incurred as of December 31,1997, which have been added back in
      determining the estimated net proceeds of the Offering.     
     
  (h) Reflects the repayment of CSI's bridge debt of $2,840,000 which is
      payable upon successful completion of the Offering. Reflects the write-
      offs to accumulated deficit totalling $1,245,127 of the unamortized
      debt issuance costs of $449,927 and the unamortized discount on such
      debt of $795,200.     
     
  (i) Reflects the cash payment of $1,750,000 due to the shareholders of ITC
      upon the successful completion of the Offering in accordance with the
      terms of the acquisition (this pro forma adjustment does not take into
      consideration any additional deposits which would have been made in
      1998)     
     
  (j) Reflects payment amount due to a former officer of CSI pursuant to a
      settlement agreement.

                       INDEPENDENT AUDITORS' REPORT     
   
Communications Systems International, Inc.     
   
Colorado Springs, Colorado     
   
  We have audited the accompanying balance sheets of Communications Systems
International, Inc. (CSI) as of April 30, 1996 and 1997, and the related
statements of operations, shareholders' deficit and cash flows for each of the
three years in the period ended April 30, 1997. These financial statements are
the responsibility of CSI's management. Our responsibility is to express an
opinion on these financial statements based on our audits.     
   
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.     
   
  In our opinion, such financial statements present fairly, in all material
respects, the financial position of Communications Systems International, Inc.
as of April 30, 1996 and 1997, and the results of its operations and its cash
flows for each of the three years in the period ended April 30, 1997 in
conformity with generally accepted accounting principles.     
   
  The accompanying financial statements have been prepared assuming that CSI
will continue as a going concern. As discussed in Note 1 to the financial
statements, CSI's substantial losses since inception and working capital
deficit at April 30, 1997 raise substantial doubt about CSI's ability to
continue as a going concern. Management's plans in regard to these matters are
described in Note 1. The financial statements do not include any adjustments
that might result from the outcome of this uncertainty.

                      NOTES TO FINANCIAL STATEMENTS     
    
 (INFORMATION AS OF AND FOR THE NINE MONTHS ENDED JANUARY 31, 1997 AND 1998 IS
                                UNAUDITED)     
   
1.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES     
   
  Communications Systems International, Inc. (CSI) is a rapidly growing
provider of international telecommunications services principally in South
America, Europe, the Pacific Rim, Central America and South Africa. CSI
purchases long distance time increments from established international
telecommunication carriers and derives its revenue by providing competitively
priced international telecommunications services combined with enhanced
technical capabilities and services in markets that are underserved by large
telecommunications providers and incumbent telephone operators (ITOs).     
   
  The accompanying financial statements have been prepared in conformity with
generally accepted accounting principles, which contemplates continuation of
CSI as a going concern. CSI has sustained substantial operating losses since
inception through April 30, 1997. In addition, CSI has used substantial
amounts of working capital in its operations. At April 30, 1997, current
liabilities exceeded current assets by $2,331,255 and total liabilities
exceeded total assets by $1,668,645.     
   
  In fiscal 1997, CSI's management took actions to increase its revenue
through increased calling volume and, as a result, CSI has been able to
negotiate more favorable rates with its telecommunications carriers enabling
CSI to reduce its cost of revenue per unit of service sold. These steps have
enabled CSI to significantly improve its gross margins during the year ended
April 30, 1997 and the nine-month period ended January 31, 1998.     
   
  In fiscal 1998, in order to raise additional working capital and satisfy
certain obligations, CSI issued mandatorily redeemable convertible promissory
notes (see Note 3) in a private offering. Also in fiscal 1998, management
believes it will be successful in raising a significant amount of equity
capital in a public offering (see Note 12) and intends to use the proceeds for
repayment of the mandatorily redeemable convertible promissory notes, and to
complete the pending acquisitions (see Note 13) as well as repay existing
obligations, working capital, development of new service offerings and
enhancement and expansion of existing services.     
   
  Management believes that these actions and others presently being taken will
allow CSI to successfully meet its obligations and achieve and sustain
profitable levels of operations.     
   
  Accounts Receivable--Accounts receivable are presented net of an allowance
for doubtful accounts which is based on management's estimate of uncollectible
accounts. At April 30, 1996 and 1997 and January 31, 1998, the allowance for
doubtful accounts was $164,245, $186,489 and $403,991, respectively.     
   
  Property and Equipment--Property and equipment are recorded at cost.
Depreciation is provided on a straight-line method over the estimated useful
lives of the respective assets (generally five to seven years).     
   
  Use of Estimates--The preparation of CSI's financial statements in
conformity with generally accepted accounting principles requires management
to make estimates and assumptions that affect the reported amounts of assets
and liabilities and disclosure of contingent assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.     
   
  Stock-Based Compensation--Statement of Financial Accounting Standards No.
123, "Accounting for Stock-Based Compensation," encourages, but does not
require companies to record compensation cost for stock-based employee
compensation plans at fair value. CSI has elected to continue to account for
stock-based compensation using the intrinsic value method prescribed in
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees," and related interpretations. Accordingly, compensation cost for
stock options is measured as the excess, if any, of the quoted market price of
CSI's stock at the date of the grant over the amount an employee must pay to
acquire the stock. See Note 5.

                NOTES TO FINANCIAL STATEMENTS--(CONTINUED)     
   
  Per Share Amounts--The net loss per share is based upon the weighted average
of common shares outstanding during the period; the effect of outstanding stock
options and warrants is antidilutive.     
   
  Interim Financial Statements--The financial statements of CSI for the nine
months ended January 31, 1997 and 1998 are unaudited. In management's opinion,
the financial statements reflect all adjustments necessary for a fair
presentation of the results for these periods, all adjustments being of a
normal and recurring nature. CSI's interim financial statements may not be
indicative of the results of operations for a full year.

  On October 9, 1997, CSI entered into an agreement with a long distance
carrier to which CSI had a note payable with an outstanding balance of
$1,485,909 as of April 30, 1997. The agreement provided that the carrier would
accept a payment of $650,000 in full satisfaction of the remaining principal
balance on the note ($1,458,292 at October 9, 1997) and all accrued and unpaid
interest thereon ($116,755 at October 9, 1997). CSI was also obligated to pay
a fee of $178,047 to one of the companies which CSI intends to acquire (see
Note 13) for assistance in obtaining this agreement. CSI recognized a gain of
$747,000 in December 1997 upon the payment of the $650,000 liability.     
   
  CSI issued mandatorily redeemable convertible promissory notes totalling
$2,840,000 on December 30, 1997 in a private placement offering,
collateralized by a first security interest on all unpledged assets of CSI and
a second security interest on all assets subject to a prior lien. The notes
are personally guaranteed as to $1,500,000 of principal and interest by two of
CSI's officers and directors ($750,000 guaranteed by each, severally). The
notes are convertible into CSI's Common Stock after nine months at a 50%
discount to the average of the closing bid price for the immediately preceding
20 trading days. The holders of the converted shares have certain registration
rights. As additional consideration for purchasing the notes, if the public
offering is (a) not completed within nine months of the closing of the
offering, the noteholder is to receive 30,000 shares of CSI's Common Stock for
each $100,000 of principal or (b) completed, the noteholder will receive a
certain number of shares valued at $40,000 based on the proposed public
offering price per share. As a result of the stock conversion rights, CSI has
recorded a discount on the notes and recognized an obligation to issue Common
Stock of $795,200. The discount is being amortized over a six-month period
since management believes CSI will complete its offering by June 30, 1998. At
January 31, 1998, the unamortized portion of the discount was $662,667. In
connection with the placement of the notes, CSI incurred debt issuance costs
of $449,927 which are also being amortized over a six-month period. At January
31, 1998, the unamortized portion of the debt issuance costs was $374,856.

                NOTES TO FINANCIAL STATEMENTS--(CONTINUED)     
   
  As of April 30, 1997, all of CSI's obligations are classified as current
liabilities due to their repayment terms or CSI's failure to make timely
principal and interest payments.     
   
4.SHAREHOLDERS' EQUITY     
          
  During the year ended April 30, 1995, CSI accepted deposits for purchase of
1,687,263 shares of its common stock in excess of the number of shares
authorized. In September 1995, CSI's shareholders voted to increase the number
of authorized shares of common stock to 25,000,000 shares and the subscribed
shares were issued.     
   
  CSI offered up to 1,000,000 shares of its no par Common Stock at a purchase
price of $.50 per share under a private placement memorandum dated January 31,
1995. At April 30, 1995, 185,000 shares had been subscribed. During the year
ended April 30, 1996, the offering was fully subscribed.     
   
  In September 1995, in an effort to increase the number of shareholders of
CSI's Common Stock, CSI's shareholders approved a plan of merger to acquire
all of the outstanding shares of Redden Dynamics Corporation (Redden) for
$34,500 cash and 818,774 shares of CSI's Common Stock. Under the plan of
merger, the shareholders of Redden received one share of CSI's Common Stock in
exchange for each 13.5 shares of Redden stock. Effective as of the date of the
merger, all shares of Redden were cancelled, the assets of Redden became
assets of CSI and Redden ceased to exist. Redden's only recorded asset
consisted of $11,050 of organizational costs. Redden had no liabilities and
had no revenue or expenses since inception. Subsequent to the merger, CSI
determined that Redden's assets were of no value to CSI. Accordingly, no
amounts have been recognized for the issuance of the CSI Common Stock in
connection with the merger of Redden.     
   
  During the year ended April 30, 1996, CSI issued 657,910 shares of its
Common Stock in exchange for financial and technological consulting services.
The cost of the services provided of $312,775 has been charged to operations.
       
  During the year ended April 30, 1997, CSI sold 61,500 shares of Common Stock
for $2.00 per share and received $111,200 after offering costs of $11,800.
       
  In August 1996, CSI acquired the net assets of an affiliated company through
the issuance of 179,076 shares of CSI's Common Stock to certain shareholders
of the affiliate and granted options to purchase 97,000 shares of CSI's Common
Stock (see Note 5) to certain other shareholders of the affiliate. The assets
acquired totalling $72,749 and liabilities assumed totalling $22,756 were
recorded by CSI at the affiliate's net book value. Pro forma information
combining the results of operations of CSI and the affiliate as if the
acquisition had occurred at the beginning of fiscal 1996 and 1997 has not been
presented as such information would not differ significantly from the reported
amounts.     
   
  During the year ended April 30, 1997, CSI sold convertible notes totalling
$320,000, of which $190,000 of such notes were issued to three current
directors of CSI. The notes, bearing interest at 10%, are convertible into
shares of CSI's Common Stock at a conversion price equal to 90% of the average
of the bid and ask price on the day prior to conversion. As of April 30, 1997,
the holders of notes totalling $270,000 principal amount had converted their
notes and accrued interest of $4,342 into 326,027 shares of stock; upon
conversion, CSI charged the remaining unamortized deferred financing costs of
$22,834 relating to such notes against the recorded amount of Common Stock.
During the nine months ended January 31, 1998, CSI sold an additional $95,000
principal amount of the convertible notes, and noteholders converted notes
totalling $115,000 principal amount and accrued interest of $475 into 231,426
shares of Common Stock. Upon conversion, CSI charged unamortized deferred
financing costs of $1,166 relating to such notes against the recorded amount
of Common Stock.     
   
  During the year ended April 30, 1997, CSI issued 140,000 shares of its
Common Stock in exchange for financial and technological consulting services.
The cost of the services provided of $34,224 has been charged to operations.

                NOTES TO FINANCIAL STATEMENTS--(CONTINUED)     
   
  CSI has notes receivable from a shareholder totalling $35,000 which resulted
from the issuance of Common Stock, bear interest at 10% and are payable on
demand.     
   
  In August 1997, CSI entered into settlement agreements with two former
employees who were also shareholders of CSI to repurchase 841,126 shares of
its Common Stock from such individuals for $.55 per share, or a total price of
$462,619. The agreements require payments by CSI of $220,000 no later than
September 12, 1997, $110,000 no later than February 11, 1998, and $132,619 no
later than August 11, 1998. As of January 31, 1998, CSI has made payments
totalling $220,000 to these individuals and received 400,000 shares of its
Common Stock which have been retired. As of January 31, 1998, CSI has recorded
a liability for the remaining payments totalling $242,619 and treasury stock
for the shares that it is committed to purchase.     
   
  In a private placement in September and October 1997, CSI sold 908,641
shares of its Common Stock for $499,752, or $.55 per share, the proceeds of
which were partially used to repurchase the shares described in the preceding
paragraph.     
   
5.STOCK OPTIONS     
   
  Under the terms of CSI's non-qualified stock option plan, options to

  The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted-average
assumptions used for grants in the years ended April 30, 1996 and 1997;
expected volatility of 132%; risk-free interest rate of 6% and expected lives
of three to ten years.     
   
6.WARRANTS     
   
  During the year ended April 30, 1996, CSI issued warrants in connection with
Common Stock in exchange for financial services. The warrants provide for the
purchase of 150,000 shares of CSI's common stock at prices ranging from $1.50
to $3.50, and expire in 2000 and 2001.     
   
  In connection with the issuance of the convertible and 15% promissory notes
(see Note 3), CSI also is committed to deliver to the noteholders 58,500
warrants to purchase shares of CSI's Common Stock. The exercise price of the
warrants is equal to the bid price of such stock on the date the note was
executed and ranges from $.27 to $1.38 per share; the warrants expire in 1998
and 1999.     
   
  In connection with the placement of the mandatorily redeemable convertible
promissory notes, CSI issued to the placement agent 284,000 warrants to
purchase shares of CSI's Common Stock. The warrants are exercisable at 125% of
proposed public offering price per share; if no offering occurs within one
year from the closing of the offering of the notes, the exercise price is
reduced to 50% of the closing bid price. (See note 3)

</TABLE>    
   
  As of April 30, 1997, CSI's net operating loss carryforwards of
approximately $3,400,000 will begin expiring in the year 2009. The
carryforwards will be available for the reduction of future income tax
liabilities. As of April 30, 1997, CSI has recorded a valuation allowance to
reduce the existing deferred tax asset to an amount that is more likely than
not to be realized. The valuation allowance increased by $210,000, $860,000
and $60,000 during the years ended April 30, 1995, 1996 and 1997,
respectively. The utilization of approximately $540,000 of tax loss
carryforwards is limited to approximately $80,000 each year as a result of an
ownership change in CSI (as defined by Section 382 of the Internal Revenue
Code of 1986, as amended), which occurred in 1995. The amount of the remaining
carryforwards that can be used in any given year may be limited in the event
of additional future changes in the ownership of CSI.

8.RELATED PARTY TRANSACTIONS     
   
  CSI leases office space from a partnership in which CSI's principal
shareholder owns a general partnership interest. Rental expense under such
leases totalled $17,346, $37,592 and $87,259 for the years ended April 30,
1995, 1996 and 1997, respectively. Future annual minimum lease payments
required under such leases are as follows as of April 30, 1997:

  CSI receives periodic advances from its principal shareholder. At April 30,
1996 and 1997 and January 31, 1998, CSI had an unsecured note payable of
$159,915, $148,761 and $148,761, respectively, to its principal shareholder,
payable May 31, 1999 and bearing interest at 10%.     
   
  In fiscal year 1998, CSI entered into a settlement agreement with one of its
former officers which provided for payments totalling $63,000 through December
1997 and, a promissory note for $125,000 requiring twelve monthly payments of
$10,417 beginning January 1998. If the proposed public offering (see Note 12)
is completed prior to full payment of the note, the remaining balance is due.
Such amounts have been reflected as general and administrative expense for the
nine months ended January 31, 1998.     
   
9.MAJOR CUSTOMERS, SUPPLIERS AND FOREIGN MARKETS     
   
  CSI's major markets are currently in Argentina, Brazil, Europe and South
Africa. As a result, CSI's operations may be adversely affected by significant
fluctuations in the value of the U.S. dollar against certain foreign
currencies, the enactment of exchange controls, or foreign governmental or
regulatory restrictions on the transfer of funds. CSI currently prices all its
products and services in terms of U.S. dollars. Significant fluctuations in
the value of the U.S. dollar in relation to currencies in countries where CSI
conducts operations can greatly affect the competitive price position of CSI's
products and services. CSI's distributors in Argentina and Brazil generated
revenue (as a percentage of CSI's total revenue) as follows:

10.COMMITMENTS AND CONTINGENCIES     
          
  In September 1996, CSI entered into a consulting and royalty agreement to
acquire the rights of to a switching system which is installed at customer
locations. Under the terms of the agreement, CSI is required to pay the
developer a monthly royalty equal to 4% of CSI's gross collected revenue
related to the system. In addition, CSI is also required to provide monthly
funding for the installation of two systems. In the event that CSI fails to
provide such funds and installation is prevented or delayed by more than sixty
days, the royalty payment to the developer is increased to 6%. CSI has the
option to buy out the royalty obligation for $1,500,000 prior to September
1997; after September 1997, the buyout amount is the greater of $2,500,000 or
an amount equal to three times the aggregate royalty payments for the first
twelve months of the agreement. In addition, for each installation, CSI agrees
to pay the developer $1,500 if such installation produces gross revenue
between $10,000 and $20,000 in the first full billing month, and $3,000 if
such revenue exceed $20,000. The developer has agreed to provide ongoing
maintenance, support and consulting while the system is in operation at a rate
of $4,000 per month through September 1, 1997, and $5,200 thereafter. The
agreement is in effect for as long as the system is operational until
September 1, 2006, unless earlier terminated.     
   
  CSI has employment agreements with certain of its officers which provide for
annual salaries totalling $400,000 and expire in 1999 and 2000. One of the
agreements requires annual increases of 4%.     
   
  CSI is subject to a $100,000 claim by a manufacturer from which CSI received
telecommunications equipment. CSI believes that the equipment is not suitable
for its intended purpose and that the manufacturer misrepresented certain
matters pertaining to this equipment. CSI has offered to return the equipment
in exchange for a release of the manufacturer's claim and the manufacturer has
rejected CSI's offer. CSI has not made a provision for any loss that might
result from the outcome of this matter; however, CSI believes that the
ultimate resolution of this claim will not have a material adverse effect on
its financial position or results of operations.     
   
  CSI has agreements with certain of its carriers that provide for guaranteed
rates and minimum annual usage. Certain agreements require CSI to make
deposits with the carriers; such deposits totalled $25,000, $95,000 and
$220,000 at April 30, 1996, and 1997 and January 31, 1998, respectively. The
agreements expire through 1999 and require minimum annual usage as follows:

11.PROPOSED STOCK SPLIT     
   
  In December 1997, CSI's Board of Directors authorized a reverse split of
CSI's common stock (not to exceed 1-for-30) whereby CSI will issue one share
of common stock in exchange for a number of shares yet to be determined. The
authorization for the reverse split was approved by CSI's shareholders in
January 1998. All references to numbers of shares, options and warrants and
per share amounts, including exercise prices, in the accompanying financial
statements and related notes have not been restated to reflect any potential
reverse stock split.     
   
12.PROPOSED PUBLIC OFFERING     
   
  CSI is planning a public offering of its Common Stock in 1998, the net
proceeds from which are expected to be used to complete the acquisitions
described in Note 13, to repay the mandatorily redeemable promissory notes
described in Note 3, for working capital, development of new service
offerings, and enhancement and expansion of existing services.

13.PENDING ACQUISITIONS     
   
  CSI has entered into an agreement to acquire all of the outstanding stock of
International Telephone Company (ITC), another telecommunications company that
provides services similar to that of CSI. The purchase price of $5,370,000 is
to be satisfied by the payment of $3,300,000 in cash and the issuance of
shares of CSI's Common Stock valued at $2,070,000 (before any discount) based
on the public offering per share price in CSI's proposed public offering (see
Note 12). The agreement provides that $1,325,000 of the cash payment will be
placed into an escrow account to satisfy any potential claims against the
selling shareholders, and for the shares of CSI's Common Stock to be issued to
the selling shareholders one year after the acquisition is completed to ensure
compliance with certain provisions of the agreement. Included in deposits in
the accompanying balance sheets at April 30, 1997 and January 31, 1998 are
standstill deposits totalling $25,000 and $225,000, respectively, which are
nonrefundable and are to be credited against the purchase price. The agreement
also requires additional standstill deposits to be made prior to the expected
acquisition date. The acquisition is expected to occur upon closing of CSI's
proposed public offering.     
   
  On April 22, 1998, CSI entered into a letter of intent to acquire all of the
outstanding common stock of GlobalTel Resources, Inc. (GlobalTel), another
telecommunications company which also provides services similar to that of
CSI, through the issuance of a number of shares of CSI's Common Stock to be
determined.     
   
  CSI's acquisitions of GlobalTel and ITC will be accounted for by the
purchase method.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
   
To GlobalTel Resources, Inc.:     
   
  We have audited the accompanying consolidated balance sheets of GlobalTel
Resources, Inc. (a Washington corporation) and subsidiaries as of December 31,
1996 and 1997, and the related consolidated statements of operations, common
stock subject to rescission and shareholders' deficit and cash flows for each
of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of GlobalTel's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.     
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
   
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of GlobalTel Resources, Inc.
and subsidiaries as of December 31, 1996 and 1997, and the results of their
operations and their cash flows for each of the three years in the period
ended December 31, 1997, in conformity with generally accepted accounting
principles.     
   
  The accompanying consolidated financial statements have been prepared
assuming that GlobalTel will continue as a going concern. As discussed in
Notes 1 and 5, a significant portion of GlobalTel's bridge loans call for
principal repayment during 1998. In addition, as discussed in Note 6,
GlobalTel plans to commence an offer to rescind a significant portion of
GlobalTel's common stock and bridge loans. Management's current projections
indicate that there will not be sufficient cash flows from operations to fund
these obligations. These matters raise substantial doubt about GlobalTel's
ability to continue as a going concern. Management's plans in regard to these
matters are discussed in Note 1. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               
                            DECEMBER 31, 1997     
 
1. DESCRIPTION OF THE BUSINESS
   
  GlobalTel Resources, Inc. ("GlobalTel"), a Washington corporation, was
formed on November 17, 1994, to provide international telecommunications
services. GlobalTel began operations in 1995 with its entry into the
international call-reorigination business. GlobalTel also markets long-
distance calling cards and enhanced voice services including voice mail and
conference calling.     
   
  On December 29, 1995, GlobalTel acquired GFP Group, Inc. ("GFP"), a
Washington corporation formed on September 15, 1995. GFP was formed primarily
for the purpose of acquiring Ratsten International Telecommunications, Inc.
d/b/a Netstar Telecommunications, Inc. ("Ratsten") and was thereafter acquired
by GlobalTel. Ratsten held certain license rights critical to GlobalTel's
mission of providing global telecommunications services.     
   
  GlobalTel provides global long-distance call-reorigination services through
Primecall, Inc., ("Primecall") a wholly owned subsidiary. GlobalTel began
generating revenue in March 1995. Prior to January 1, 1995, GlobalTel's sole
operations consisted of general and administrative activities, which amounted
to $75,638 for the period ended December 31, 1994.     
   
  GlobalTel has generated substantial operating losses and has a limited
operating history. GlobalTel must be considered in light of the risks,
expenses and difficulties frequently encountered by companies in their early
stage of operations. Losses may continue until such time, if ever, that
GlobalTel is able to generate a level of revenue sufficient to offset its cost
structure. There can be no assurance that GlobalTel will achieve increased
revenue or profitable operations. To date GlobalTel's losses have been
principally funded by a combination of common and preferred stock sales and
bridge loans, which mature in 1998 and early 1999 (see Notes 3 and 5). In
addition, GlobalTel will require additional capital to effect the Recission
Offer (see Note 6), to bring current approximately $2 million of certain past
due trade accounts payable as of April 10, 1998, and to finance its short- and
long-term growth strategies. To meet these obligations, management's plans
include merging (the "Merger") with Communications Systems International, Inc.
("CSI"), a communications company located in Colorado Springs, Colorado, which
has filed a registration statement for a public offering ("the CSI Offering")
of its common stock. However, there is no assurance that the Merger or the CSI
Offering will be completed or that GlobalTel will operate profitably or will
be successful in capitalizing on perceived synergies of the Merger. These
matters raise substantial doubt about GlobalTel's ability to continue as a
going concern. The consolidated financial statements do not include any
adjustments that might results from the outcome of this uncertainty.     
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Consolidated Financial Statements
   
  The accompanying consolidated financial statements include the financial
accounts of GlobalTel and its wholly owned subsidiaries, Primecall and GFP.
All intercompany transactions have been eliminated.     
 
 Use of Estimates
   
  The preparation of consolidated 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,
the disclosure of contingent assets and liabilities at the date of the
financial statements and the reported amounts of revenue and expenses during
the reporting periods. Actual results could differ from those estimates.

                            DECEMBER 31, 1997     
 
         
 Cash
   
  For purposes of the consolidated statements of cash flows, cash includes all
amounts on deposit with financial institutions. GlobalTel has no short-term
investments.     
   
 Property and Equipment     
   
  Property and equipment consist primarily of office furniture, computer and
telecommunications equipment. Property and equipment are recorded at cost and
are depreciated using the straight-line method over the estimated useful lives
of the related assets, which range from 5 to 10 years. Repairs, maintenance
and minor renewals are charged to expense as incurred. Major renewals and
betterments which substantially extend the useful life of the assets are
capitalized. Upon sale or other disposition of assets, the cost and the
related accumulated depreciation are removed from the accounts and a gain or
loss, if any, is reflected in the consolidated statements of operations.     
   
  Property and equipment is composed of the following:

</TABLE>    
   
  GlobalTel recorded depreciation expense of $55,272, $76,884, and $206,763
for the years ended December 31, 1995, 1996 and 1997, respectively.     
 
 Other Assets
   
  Other assets consist primarily of a license agreement, organizational costs,
bridge loan issue costs and telecommunications equipment to be placed in
service. The license agreement purchased by GlobalTel (see Note 7) is being
amortized on a straight-line basis over 15 years. GlobalTel recorded
amortization expense related to the license agreement of $1,970, $11,825 and
$11,825 for the years ended December 31, 1995, 1996 and 1997, respectively.     
   
  Certain organizational costs (primarily legal expenses) incurred in
connection with establishing and organizing GlobalTel and its subsidiaries are
being amortized on a straight-line basis over a period of five years.
GlobalTel recorded amortization expense related to these organizational costs
of $53,820, $9,579 and $34,732 for the years ended December 31, 1995, 1996 and
1997, respectively.     
   
  Bridge loan issue costs incurred in connection with obtaining bridge loans
have been deferred and are being amortized into interest expense on a
straight-line basis (which approximates the effective interest method) over
the terms of the loans. For the years ended 1995, 1996 and 1997, GlobalTel
recognized $7,904, $28,999 and $214,666, respectively, in additional interest
expense from amortization of the bridge loan issue costs.     
   
  For the years ended December 31, 1996 and 1997, GlobalTel held
telecommunications equipment to be placed in service of $374,075 and $519,688,
respectively. GlobalTel has not yet placed this equipment into service as
certain components necessary to complete the installation have not yet been
acquired.

  As of December 31, 1996, GlobalTel had deferred salaries payable to certain
members of GlobalTel's management. Interest accrued on the deferred balances
at an annual rate of 10%. During 1997, an additional $517,856 of deferred
salaries was accrued. During the year ended December 31, 1997, these deferred
salaries were converted to common stock warrants (see Note 3).     
 
 Equity-Based Compensation
   
  GlobalTel accounts for employee equity-based compensation following the
provisions of Accounting Principles Board Opinion No. 25 ("APB 25"),
"Accounting for Stock Issued to Employees." In accordance with the provisions
of APB 25, GlobalTel has not recognized deferred compensation or compensation
expense in connection with its equity-based plans as the exercise price of the
options granted was equal to the fair value of the underlying equity
instrument at the date of grant.     
   
  Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting
for Stock-Based Compensation," requires expanded disclosures of equity-based
compensation arrangements with employees and does not require, but encourages,
compensation cost to be measured based on the fair value of equity instruments
when awarded. GlobalTel, as allowed, intends to continue to measure employee
equity-based compensation under APB 25, which recognizes compensation cost
based on the intrinsic value of the equity instrument awarded.     
   
 Revenue Recognition and Cost of Revenue     
   
  Revenue and related cost of revenue are recognized in the period services
are provided. The related accruals for revenue, cost of revenue and customer
prepayments are included in the accompanying consolidated balance sheets.     
   
 Research and Development     
   
  Research and development costs are expensed as incurred, and are included in
general and administrative expense in the accompanying consolidated statements
of operations.     
 
 Income Taxes
   
  GlobalTel accounts for income taxes using the asset and liability method. To
date, GlobalTel has fully reserved all net deferred tax assets.     
 
 Concentrations of Risk
   
  During October 1996, GlobalTel began reselling international long-distance
service to other telecommunications carriers on a wholesale basis. As of
December 31, 1996, $793,000 of GlobalTel's accounts receivable was due from a
single telecommunications carrier. This receivable was fully collected during
the first quarter of 1997.

  Cost of revenue as a percentage of revenue does not vary significantly from
region to region. There are no other direct costs incurred outside the United
States, nor does GlobalTel own material assets located outside of the United
States. The continued legality and competitive advantage of call-reorigination
businesses in certain foreign countries is uncertain due to changing
regulatory environments.     
   
  GlobalTel's call-reorigination business is facilitated by a single switch
located in Los Angeles, California.     
   
 Basic Loss Per Share     
          
  In February 1997, the Financial Accounting Standards Board issued SFAS No.
128, "Earnings Per Share," ("SFAS 128") which revises the calculation and
presentation of earnings per share. SFAS 128 is effective for GlobalTel's
fiscal year ending December 31, 1997, and retroactive application is required.
Basic loss per share for all periods presented in the accompanying
consolidated statements of operations has been computed under the provisions
of SFAS 128. As such, the anti-dilutive effects of convertible securities have
been excluded.     
   
 Reclassifications     
   
  Certain prior year amounts have been reclassified to conform with the
current year presentation.     
   
 Recently Issued Accounting Pronouncements     
   
  In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-5, "Reporting on the Costs of Start-Up Activities,"
(the "SOP") which requires costs of start-up activities and organization costs
to be expensed as incurred. The SOP is effective for financial statements with
fiscal years beginning after December 15, 1998, although earlier application
is encouraged. In the period that the SOP is adopted, GlobalTel will be
required to write-off any previously deferred start-up or organizational costs
as a cumulative effect of a change in accounting principle. Management intends
to adopt the SOP in the first quarter of 1998, which will result in a charge
of approximately $75,000 to GlobalTel's consolidated statement of operations.
Effects of retroactive application are not required by the SOP upon adoption.

3. SHAREHOLDERS' DEFICIT
 
 Series A Convertible Preferred Stock
   
  Each share of Series A convertible preferred stock is entitled to a dividend
at an annual rate of 6% of the issuance price, deferrable at the election of
GlobalTel but payable in preference to dividends on any other securities
issued by GlobalTel. All accrued and unpaid dividends on a share must be paid
before dividends on other securities. Each share is also entitled, in
liquidation, to a preferred distribution of the initial issuance price plus
all accrued but unpaid dividends. Each share is subject to automatic
conversion to common stock upon the sale of all or substantially all of the
assets of GlobalTel, an election to convert by two-thirds of the holders of
such shares, or upon the closing of an initial public offering ("IPO") of
GlobalTel, the net proceeds of which exceed $15 million if certain other
conditions are satisfied. Any unpaid cumulative dividends at the time of
conversion may be paid at the option of GlobalTel in cash, common stock, or as
notes payable to the preferred shareholders. Each share of Series A preferred
stock has a voting right based upon the number of shares of common stock into
which the Series A preferred stock would then be convertible, in addition to
certain demand and piggyback registration rights.     
   
  During 1996, GlobalTel incurred $58,088 in connection with its issuance of
Series A convertible preferred stock. These costs were capitalized as other
long-term assets in the accompanying December 31, 1996 consolidated balance
sheet and were subsequently reclassified as a charge to equity in connection
with GlobalTel's private placement of Series A convertible preferred stock.
    
 Common Stock
   
  During 1995, GlobalTel executed a stock purchase agreement with certain
common shareholders to buy back 262,573 shares of GlobalTel's common stock at
a price of $5.50 per share. GlobalTel paid $200,000 in cash and issued
$1,244,153 in promissory notes bearing interest at 8% to finance the
repurchase. These promissory notes were paid in full as of December 31, 1996.
       
  During 1997, several bridge loan holders accepted an offer from GlobalTel to
convert their bridge loans in the amount of $2,835,208, and related unpaid
interest of $327,218 into 574,987 shares of common stock at a value equal to
$5.50 per share. The net amount of bridge loans converted to common stock
included a charge of approximately $28,000 relating to the unamortized bridge
loan issue costs that were simultaneously written off.     
   
  During September 1997, GlobalTel issued 24,242 shares of common stock with a
value of $133,333 to a former employee in satisfaction of GlobalTel's
obligations under the employee's severance agreement. The value of the common
stock issued was charged to compensation expense in the accompanying
consolidated statement of operations for the year ended December 31, 1997.
       
  In November 1997, the Board of Directors ("the Board") approved a reverse
common stock split and increased the authorized number of common shares from
20 million to 50 million. The ratio of the reverse common stock split is 1:5.
All share and per share amounts have been retroactively adjusted in these
consolidated financial statements to reflect the reverse common stock split.
       
  During 1997, an aggregate of $207,705 in trade payables due to certain
vendors were converted into 37,765 shares of common stock. Also during 1997,
GlobalTel issued 14,000 shares of common stock to certain Board members and
others in recognition of past services rendered to GlobalTel. GlobalTel
recognized consulting expense of $77,000 in connection with these stock
issuances.     
 
 Equity-Based Compensation
   
  During 1996, GlobalTel approved the 1996 Stock Option Plan ("the Plan")
which provides for the granting of qualified and nonqualified stock options.
GlobalTel has reserved 520,000 shares of common stock for granting of stock
options under the Plan. During February 1998, GlobalTel's shareholders
approved an amendment to the Plan to increase the shares available for grants
to 700,000 shares of common stock. GlobalTel's Board has the authority to
determine all matters relating to options to be granted under the Plan,
including the selection of

  There were 13,100, 63,609 and 162,546 options exercisable as of December 31,
1995, 1996 and 1997, respectively. The outstanding options at December 31,
1997 have a weighted average remaining contractual life of 8.9 years. As of
December 31, 1997, there were 301,574 shares available for future option
grants.     
   
  Pro forma information regarding results of operations and loss per share is
required by SFAS 123 for awards granted after December 31, 1994 as if
GlobalTel had accounted for its stock-based awards to employees under a
valuation method permitted by SFAS 123. The value of GlobalTel's stock-based
awards to employees in 1996 and 1997 was estimated using the minimum value
method, which does not consider stock price volatility. Had compensation cost
for the Plan been determined consistent with SFAS 123, GlobalTel's net loss
for the years ended December 31, 1995, 1996 and 1997 would have been increased
to $1,748,144, $5,918,197 and $7,930,158, respectively. Also under SFAS 123,
GlobalTel's basic loss per share would have been increased to $2.78, $5.93 and
$6.53, respectively.     
   
  The weighted average fair value per option of GlobalTel's stock-based awards
granted to employees was $1.05, $0.91 and $0.90 as of December 31, 1995, 1996
and 1997, respectively, and was estimated assuming no expected dividends and
the following weighted average assumptions:

  In connection with the bridge loans issued by GlobalTel, warrants to
purchase 78,910 and 209,489 shares of GlobalTel's common stock were issued in
1996 and 1997, respectively. These warrants generally provide for increases in
the number of shares of common stock issuable if GlobalTel has not closed a
major financing transaction within specified periods. All of these warrants
were exercisable immediately upon issuance. GlobalTel estimated the value of
these warrants to be $41,555 and $197,584 in 1996 and 1997, respectively.     
   
  GlobalTel also issued warrants to various individuals in consideration for
consulting and other services received. With respect to the 1996 warrants,
30,000 vest upon the earlier of two years or the filing of a registration
statement in connection with a public offering. The remaining 25,800 warrants
were exercisable immediately upon issuance. The 1997 warrants were also
immediately exercisable upon issuance. The fair market value of the 1996
warrants when issued were not considered to be material. GlobalTel recognized
consulting expense of $187,993 with respect to the 1997 grants.     
   
  During 1997, certain former and current employees accepted common stock
warrants in lieu of salaries owed to them. Accordingly, deferred salaries of
$1,184,856 were converted into warrants to purchase 215,428 shares of common
stock with an exercise price of $0.05 per share. These warrants were
immediately exercisable upon issuance and have a three-year term.     
   
  During 1997, the Board amended certain common stock warrant agreements
whereby certain warrant holders could exercise their warrants at a price of
$3.50 per share in a cashless conversion to common stock rather than at the
original exercise price of $5.50 per share upon GlobalTel successfully
completing an IPO by April 30, 1998, at which time the amendments will expire.
Warrant holders representing 264,760 shares of common stock had indicated
their intention to exercise their warrants under these amended terms. As a
result of the amendment to these warrant agreements, GlobalTel recognized
$529,521 of additional debt discount, of which $296,985 resulted in additional
interest expense in 1997. The remaining debt discount will be amortized to
April 30, 1998.

  GlobalTel's net operating loss carryforward of approximately $9,794,000 as
of December 31, 1997 is subject to limitations and expires in 2012. GlobalTel
has determined that its deferred tax assets do not satisfy the recognition
criteria set forth under the provisions of SFAS No. 109, "Accounting for
Income Taxes." Accordingly, a valuation allowance has been recorded against
the applicable deferred tax assets. Therefore, no tax benefits have been
recorded in the accompanying consolidated statements of operations. The
valuation allowance increased by $538,000, $1,990,000 and $2,647,000 during
1995, 1996 and 1997, respectively.     
   
  The difference between the statutory tax rate of approximately 34% and the
tax benefit of zero recorded by GlobalTel is primarily due to GlobalTel's full
valuation allowance against its net deferred tax assets.     
 
5. BRIDGE LOANS
   
  To fund operations and capital expenditures, GlobalTel obtained bridge loans
from certain investors, some of whom are shareholders or management of
GlobalTel. All bridge loans bear interest at 10% annually and in certain cases
increase to 12% if the loans are past due. In addition, stock warrants were
granted to certain of these investors as discussed in Note 3. Bridge loans
outstanding were:

</TABLE>    
   
  During November and December 1997, GlobalTel obtained additional bridge note
financing of $2,865,800, $25,000 of which was from a related party. These
notes bear interest at an annual rate of 10% and are due in full at the
earlier of the closing of an IPO or January 1999. In addition, following the
closing of an IPO, each holder of these notes will receive shares of common
stock equal to the initial principal amount of the note divided by the IPO
price per share. This obligation to issue stock was valued at $1,008,109 and
is included as a component of shareholders' deficit in the accompanying
December 31, 1997 consolidated balance sheet. The offsetting charge was
recorded as debt discount and will be amortized to June 30, 1998. As of
December 31, 1997, GlobalTel had recognized $146,838 of interest expense from
amortization of the debt discount. If an IPO has not closed by July 1, 1998,
these bridge note holders will have the right to receive warrants to purchase
shares of common stock in lieu of the GlobalTel common stock issuable on
closing of an IPO equal to the initial principal amount of the note divided by
$5.50. The warrants associated with these bridge loans will have an exercise
price of $5.50 per share. Closing costs incurred associated with these notes
included approximately $280,000 in cash and 23,165 shares of common stock at
$5.50 per share. The total amount of this consideration was recorded as bridge
loan issue costs to be amortized over the life of the loan.

6. SECURITIES SUBJECT TO RESCISSION
   
  GlobalTel believes that certain of its outstanding shares of common stock
("Rescission Stock") and bridge loans and warrants to purchase shares of
common stock (collectively, the "Rescission Securities") may have been issued
in violation of certain state securities laws. As a result, conditioned on
completion of the proposed Merger and the CSI Offering, GlobalTel plans to
offer to rescind such prior sales by offering to repurchase the Rescission
Securities (the "Rescission Offer") at the price originally paid plus interest
at the annual statutory rate of eight percent from the date of purchase to the
expiration of the Rescission Offer. As such, the shares of common stock and
bridge loans making up the Rescission Securities have been classified as
common stock subject to rescission and current liabilities, respectively, in
the accompanying consolidated financial statements. As of December 31, 1997,
there were 496,466 shares of common stock, $350,000 in aggregate principal
amounts of bridge loans and warrants to purchase an aggregate of approximately
35,000 shares of common stock identified for possible rescission. In addition,
GlobalTel expects to repay $455,000 in bridge loans from proceeds of the CSI
Offering that would otherwise be identified for possible rescission. If all
holders of Rescission Securities as of December 31, 1997 were to accept the
Rescission Offer, GlobalTel would be required to pay approximately $3.1
million including statutory accrued interest.     
   
  GlobalTel estimates that the total amount of its obligation for the
statutory accrued interest with respect to Rescission Stock could aggregate
approximately $278,000 as of December 31, 1997, if all offerees holding
Rescission Stock were to accept the Rescission Offer. Because of the
contingent nature of this liability and because the ultimate amount to be
paid, if any, is not presently known, the potential interest liability with
respect to Rescission Stock has not been accrued in the accompanying
consolidated financial statements, but will be recorded as an expense and a
liability of GlobalTel if and when the shares of common stock subject to
rescission are tendered pursuant to the Rescission Offer. The statutory rate
of interest with respect to the bridge loans covered by the Rescission Offer
is less than the interest that has already been accrued by GlobalTel under the
original terms of the bridge loans.     
   
  GlobalTel plans to make the Rescission Offer if the CSI Offering and the
Merger are completed. A portion of the net proceeds of the CSI Offering will
be used to fund payments pursuant to the repurchase of the Rescission
Securities, if any are required. However, there can be no assurance that the
proposed Merger and CSI Offering will be successfully completed. The
consolidated financial statements do not include any adjustments that might
result from the outcome of the Rescission Offer. Furthermore, notwithstanding
the Rescission Offer, there can be no assurance that GlobalTel will not be
subject to penalties or fines relating to past issuances or that other holders
of securities from GlobalTel will not assert or prevail in claims against
GlobalTel for rescission or damages under state or federal securities laws.
    
       
7. ACQUISITIONS
 
 Ratsten International Telecommunications, Inc.
   
  On October 18, 1995, GFP purchased 50% of the outstanding common stock of
Ratsten for $100,000 and the other 50% for 108,791 shares of GFP's common
stock in a business acquisition accounted for using the purchase method of
accounting, the purpose of which was to acquire certain licensing rights held
by Ratsten. Prior to the Ratsten acquisition, GFP had issued 108,000 shares of
common stock to its founders. In total, GFP's common stock issued was valued
at approximately $91,600. Of the total purchase price, including the
obligation to issue shares described below, $177,368 was assigned to the
license agreement, with the remainder assigned to certain assets acquired and
liabilities assumed. No goodwill was recognized from the purchase. The sellers

                            DECEMBER 31, 1997     
         
   
Ratsten made certain warranties to GlobalTel, primarily that the license
agreement was valid and fully transferable to GFP after the purchase.     
   
  The acquisition agreement included an obligation for the issuance of an
additional 60,000 shares of GlobalTel's common stock to the sellers of one-
half of Ratsten, contingent upon GlobalTel obtaining additional financing
(other than bridge funding) in excess of a certain amount. This contingent
obligation was valued at approximately $8,400 as of the date of the agreement.
During the year ended December 31, 1997, 30,000 of these shares had been
issued.     
 
 GFP
   
  On December 29, 1995, pursuant to a share exchange agreement and statutory
share exchange, GlobalTel issued 216,791 of voting common stock on a one-for-
one basis for all of GFP's issued and outstanding common stock. GFP's only
significant asset was the license agreement which had been acquired from
Ratsten in anticipation of the share exchange agreement. GFP did not have any
material operations during the period from its inception through December 29,
1995.     
 
8. COMMITMENTS AND CONTINGENCIES

9. SUBSEQUENT EVENTS     
   
  On April 22, 1998, GlobalTel entered into a letter of intent with CSI
whereby CSI will acquire all of the outstanding common stock of GlobalTel
through the issuance of CSI's common stock in the Merger based on a conversion
formula to be determined. On April 24, 1998, CSI filed a registration
statement with the Securities and Exchange Commission related to the CSI
Offering.

                         INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors
International Telephone Company
Meriden, Connecticut
   
  We have audited the accompanying balance sheets of International Telephone
Company (ITC) as of December 31, 1996 and October 31, 1997 and the related
statements of operations, changes in shareholders' equity (capital deficiency)
and cash flows for the years ended December 31, 1995 and December 31, 1996 and
the ten months ended October 31, 1997. These financial statements are the
responsibility of ITC's management. Our responsibility is to express an
opinion on these financial statements based on our audits.     
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
   
  In our opinion, the financial statements enumerated above present fairly, in
all material respects, the financial position of International Telephone
Company, at December 31, 1996 and October 31, 1997 and the results of its
operations and its cash flows for the years ended December 31, 1995 and
December 31, 1996 and the ten months ended October 31, 1997, in accordance
with generally accepted accounting principles.     
   
  As discussed in Note G[2], one of ITC's carriers has initiated litigation
against ITC for collection of approximately $1.1 million.

                        INTERNATIONAL TELEPHONE COMPANY
 
                         NOTES TO FINANCIAL STATEMENTS
   
(UNAUDITED WITH RESPECT TO DATA AS OF JANUARY 31, 1998 AND FOR THE THREE-MONTH
          PERIODS ENDED DECEMBER 31, 1996 AND JANUARY 31, 1998)     
 
NOTE A--ORGANIZATION AND BUSINESS
   
  International Telephone Company ( "ITC") was organized in the State of
Delaware on March 3, 1993. ITC operates an international telecommunications
system offering long distance telephone service to corporations and
individuals located outside the United States.     
   
  ITC incurred a loss of $850,000 during the ten months ended October 31,
1997, including a $1.1 million claim against ITC by a carrier for usage
charges that ITC is disputing (see Note G[2]). ITC intends to vigorously
defend such claim and is attempting to settle with the carrier. If ITC is not
successful in its defense or in reaching a settlement, ITC believes that by
reducing its administrative expenses, including officers' compensation, the
cash flow from operations will be sufficient for ITC to pay such claim and to
operate as a going concern. In addition, ITC believes that it will be able to
obtain financing, if necessary.     
 
NOTE B--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 (1) Cash equivalents:
   
  ITC considers money-market funds to be cash equivalents.     
 
 (2) Revenue recognition:
   
  Telecommunication revenue is recognized at the time services are provided.
       
 (3) Cost of telecommunication revenue and selling expenses:     
 
  Cost of telecommunication services are recorded as incurred and consist
principally of charges from carriers for long distance services. Selling
expenses includes commissions to agents, which are recorded net of chargebacks
for amounts deemed uncollectible in the period the related services were
provided.
 
 (4) Depreciable assets:
 
  Depreciable assets, consisting principally of telecommunication related
equipment such as switches and computer equipment, are stated at cost.
Equipment acquired under capital leases is stated at the present value of the
future minimum lease payments.
   
  Depreciation is provided for using the straight-line method over the
estimated useful lives of the assets which range from five to seven years.
Equipment under capital leases is depreciated over the estimated useful life
of the equipment, which is generally longer than the terms of the leases since
the leases generally contain bargain purchase options which ITC intends to
exercise.     
 
 (5) Use of estimates in the preparation of financial statements:
   
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
   
(UNAUDITED WITH RESPECT TO DATA AS OF JANUARY 31, 1998 AND FOR THE THREE-MONTH
          PERIODS ENDED DECEMBER 31, 1996 AND JANUARY 31, 1998)     

 (6) Deferred income taxes:
   
  ITC provides for income taxes using the asset and liability method under
which deferred income taxes are recognized for the estimated future tax
consequences attributable to net operating loss carryforwards and temporary
differences between the basis of assets and liabilities for financial and tax
reporting purposes. Such differences relate primarily to depreciation and
equipment acquired under capital leases.     
   
 (7) Interim Financial Statements:     
   
  In the opinion of management, the unaudited balance sheet as of January 31,
1998, and the unaudited statements of operations and cash flows for the three
month periods ended December 31, 1996 and January 31, 1998, reflect all
adjustments (which include only normal recurring adjustments) necessary to
present fairly the information set forth therein. The results of operations
for interim periods are not necessarily indicative of results for the full
year.

NOTE D--LOAN PAYABLE
   
  ITC has a $250,000 line of credit, which expires on September 30, 1998, with
a financial institution. At October 31, 1997 and January 31, 1998 the balance
due under this line of credit was $3,000, which is collateralized by the
assets of ITC, including cash on deposit with such institution. Amounts due
under the line of credit bear interest at prime plus 1.5%.     
 
NOTE E--CAPITAL LEASE OBLIGATIONS
   
  ITC leases equipment under agreements with original terms of thirty-six
months, which are accounted for as capital leases. During the ten months ended
October 31, 1997, ITC acquired telecommunications equipment with a cost of
$634,000 under a capital lease. Simultaneously, ITC exchanged
telecommunications equipment with a book value of $281,000 and received
proceeds of $259,000, resulting in a loss on the exchange of $22,000. The net
book value of equipment held under capital lease was $196,000, $609,000 and
$580,000, respectively, at December 31, 1996, October 31, 1997 and January 31,
1998.     
 
  Future annual lease payments at October 31, 1997 are as follows:

  At October 31, 1997 and January 31, 1998, ITC has a net operating loss
carryforward of approximately $1,000,000 and $1,100,000, respectively,
resulting principally from its loss for income tax purposes for the ten months
ended October 31, 1997 and January 31, 1998. As a result, ITC has a deferred
tax asset of approximately $400,000 at October 31, 1997 and January 31, 1998.
ITC has provided a valuation allowance, which increased by approximately
$300,000 and during the ten months ended October 31, 1997, against the entire
deferred tax asset. Accordingly, there is no provision for federal and state
income taxes for the ten months ended October 31, 1997 and the three months
ended January 31, 1998.     
   
  The deferred tax liability of approximately $100,000 at October 31, 1997 and
January 31, 1998, respectively, represents the anticipated future tax
consequences attributable to temporary differences between the basis of assets
and liabilities for financial and tax reporting purposes. Such differences
relate to depreciation and the acquisition of equipment under a capital lease.
    
  The difference between the tax provision (benefit) and the amount that would
be computed by applying the statutory federal income tax rate to income before
taxes is attributable to the following:

NOTE G--COMMITMENTS, CONTINGENCIES AND OTHER MATTERS
 
 [1] Operating leases:
   
  ITC is subject to operating leases for its office space in Florida and
Connecticut, which include escalation clauses for increases in real estate
taxes and certain operating expenses. Rent expense for the years ended
December 31, 1995 and 1996, for the ten months ended October 31, 1997, and the
three months ended January 31, 1998 totaled $51,000, $69,000, $73,000 and
$16,000, respectively.     
 
  Future minimum lease payments at October 31, 1997 are as follows:

</TABLE>
 
 [2] Carrier payables:
   
  Pursuant to an agreement, ITC was committed to purchase transmission
capacity from a certain carrier. ITC has requested credits from the carrier
for minimum usage charges and losses incurred in connection with the
unavailability of sufficient capacity. As a result a significant balance due
to the carrier became past due. The carrier has initiated litigation against
ITC for collection of approximately $1.1 million, which is included in
accounts payable at October 31, 1997. ITC intends to vigorously defend its
position and will continue to try to reach a settlement with the carrier.     
   
  In May 1997, a carrier agreed to issue a credit for $210,000 in connection
with the settlement of charges disputed by ITC and ITC agreed to pay the
outstanding balance by December 1, 1997. The carrier subsequently presented an
invoice to ITC which did not reflect such credit and ITC believes that such
statement does not acknowledge a $100,000 payment made in January 1997. As a
result, ITC has not made the scheduled payments and accounts payable at
October 31, 1997 includes $400,000 due to this carrier.     
 
 [3] Concentration of carriers:
   
  ITC purchases transmissions capacity from a limited number of domestic
telephone carriers. ITC purchased 75% of such capacity from three telephone
carriers, 85% of such capacity from 3 carriers and 94% of such capacity from 5
carriers during the year ended December 31, 1996, the ten months ended October
31, 1997 and the three months ended January 31, 1998, respectively.     
 
 [4] Concentration of agents:
   
  During the years ended December 31, 1995 and 1996, the ten months ended
October 31, 1997 and the three months ended January 31, 1998, 3 agents were
responsible for 65%, 3 agents were responsible for 66%, 3 agents were
responsible for 53% and 4 agents were responsible for 65%, of ITC's
telecommunications revenue, respectively.

NOTE I--OTHER INCOME
   
  During the year ended December 31, 1996, ITC recognized $100,000 of income
from a nonrefundable deposit received in connection with a potential
transaction which did not close by the agreed upon date.     
   
  During the ten months ended October 31, 1997, ITC recognized $113,000 of
consulting fees in connection with assisting another telecommunications
company in settling its charges with a carrier.     
 
NOTE J--REGULATORY MATTERS
   
  In June 1993, the Federal Communications Commission (the "FCC") granted the
ITC's Application for Authority under Section 214 of the Communications Act of
1934, as amended. Pursuant to such action, ITC is authorized to resell the
public switched telecommunications services of other U.S. carriers.     
   
  ITC is subject to regulation in other countries in which it does business.
ITC believes that an adverse determination as to the permissibility of the
ITC's services under the laws and regulations of any such country would not
have a material adverse long-term effect on its business.     
   
NOTE K--PROPOSED SALE OF ITC     
   
  ITC and its stockholders have signed an agreement relating to the purchase
by Communications Systems International, Inc. ("CSI"), another
telecommunications company, of all of the outstanding shares of common stock
of ITC. ITC's stockholders have received $125,000 from CSI in connection with
such anticipated sale. ITC and CSI utilize each others' transmission capacity.
During the three months ended January 31, 1998, ITC incurred
telecommunications charges aggregating approximately $190,000 and recognized
telecommunications revenue of approximately $72,000 from CSI. There were no
significant telecommunications charges incurred or telecommunications revenue
earned from CSI during the year ended December 31, 1996 or the ten months
ended October 31, 1997.

                   COMMUNICATIONS SYSTEMS INTERNATIONAL, INC.
 
                                  COMMON STOCK
   
  This Prospectus relates to the offer and sale by certain Securityholders
(collectively, the "Selling Securityholders") of a maximum of 113,600 shares of
Common Stock of Communications Systems International, Inc. that were issued in
a private placement completed in December 1997 and    shares issuable upon the
exercise of certain warrants (collectively, the "Selling Securityholders'
Shares"). The Selling Securityholders' Shares are not part of the concurrent
underwritten offering and may not be offered or sold prior to 180 days from the
date of this Prospectus without the consent of Cohig & Associates, Inc. The
Company will not receive any proceeds from the sale of the Selling
Securityholders' Shares. See "Selling Securityholders and Plan of
Distribution."     
   
  Prior to this Offering, the Common Stock was traded sporadically in limited
amounts on the OTC Bulletin Board under the symbol CSYG. On April  , 1998, the
last reported closing high bid price of the Common Stock was $   per share. It
is currently estimated that the offering price of the Common Stock will be
between $   and $   per share after giving effect to a proposed reverse stock
split to be effective prior to the date of this Prospectus. The Company has
applied to have the Common Stock quoted on the Nasdaq SmallCap Market under the
symbol "CSGL". Upon listing on the Nasdaq SmallCap Market, the Company's Common
Stock will no longer be listed on the OTC Bulletin Board. See "Price Range of
Common Stock."     
 
  The distribution of shares of Common Stock offered hereby by the Selling
Securityholders may be effected in one or more transactions that may take place
on the over-the-counter market, including ordinary broker's transactions,
privately negotiated transactions or through sales to one or more dealers for
sale of such securities as principals, at market prices prevailing at the time
of sale, at prices relating to such prevailing market prices or at negotiated
prices. Usual and customary or specifically negotiated brokerage fees or
commissions may be paid by the Selling Securityholders.
   
THE SECURITIES OFFERED HEREBY ARE SPECULATIVE AND INVOLVE A HIGH DEGREE OF RISK
AND IMMEDIATE SUBSTANTIAL DILUTION AND SHOULD NOT BE PURCHASED BY INVESTORS WHO
CANNOT AFFORD THE LOSS OF THEIR ENTIRE INVESTMENT. SEE "RISK FACTORS" BEGINNING
ON PAGE 6.     
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE COMMISSION OR
ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
   
  The Selling Security holders and intermediaries through whom such securities
are sold may be deemed "underwriters" within the meaning of the Securities Act
of 1933, as amended (the "Securities Act") with respect to the securities
offered, and any profits realized or commission received may be deemed
underwriting compensation.     
   
  On the date of this Prospectus, a registration statement including a
prospectus of even date filed under the Securities Act with respect to an
underwritten public offering by the Company of     shares of Common Stock and
up to an additional     shares of Common Stock to cover over-allotments, if
any, was declared effective by the Securities and Exchange Commission (the
"Commission"). The Company will receive net proceeds of approximately $    from
the sale of the shares of Common Stock included in the underwritten public
offering, and will receive approximately $    in additional net proceeds if the
over-allotment option is exercised in full after payment of underwriting
discounts and commission and estimated expenses of the underwritten public
offering. See "Concurrent Offering."

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS.     
 
  The Registrant's Bylaws require the Registrant to indemnify all of its
present and former officers and directors, or any person who may have served
at the Registrant's request as an officer or a director of another corporation
in which the Registrant owns shares of capital stock or of which the
Registrant is a creditor, and the personal representatives of all such
persons, against expenses actually and necessarily incurred in connection with
the defense of any legal proceeding in which any such person was made a party
by reason of having served in such capacity, unless such person is adjudged to
be liable for negligence or misconduct in the performance of any duty owed to
the Registrant.
 
  The Registrant's Articles of Incorporation provide that no director of the
Registrant shall be liable to the Registrant or any of its shareholders for
damages caused by a breach of a fiduciary duty by such director except for the
breach of the duty of loyalty, acts or omissions not in good faith or which
involve intentional misconduct or knowing violation of the law, acts as
specified in the Colorado Business Corporation Act, or any transaction from
which such director received an improper personal benefit.
 
  Section 7-109-102 of the Colorado Business Corporation Act authorizes the
indemnification against reasonable expenses of current and former directors
made party to a proceeding if the director conducted himself in good faith, in
the case of conduct in his official capacity with the corporation, the
director reasonably believed that his conduct was in the best interests of the
corporation, in the case of a criminal proceeding, the director had no
reasonable cause to believe that his conduct was unlawful, and in all other
cases, the director reasonably believed that his conduct was at least not
opposed to the corporation's best interest. A corporation may not indemnify a
director in connection with a proceeding (1) in which a director was adjudged
liable to the corporation or, (2) charging that the director derived an
improper personal benefit in which the director was adjudged liable. Section
7-109-107 provides that a corporation may indemnify an officer to the same
extent that it may indemnify a director.
 
  The above discussion of the Registrant's Bylaws, Articles of Incorporation
and the Colorado Business Corporation Act is only a summary and is qualified
in its entirety by the full text of each of the foregoing.

  Reference is made to the Underwriting Agreement, the proposed form of which
is filed as Exhibit 1.1, in which the Underwriters agree, under certain
circumstances, to indemnify the directors and officers of the Registrant and
certain other persons against certain civil liabilities.
          
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.     
          
  Note: The information contained in this Item 15 is based on the actual
current share and per share amounts. These numbers are subject to change
pursuant to the Registrant's proposed reverse stock split.     
   
  The Registrant made the following sales of securities within the past three
years without registering such securities under the Securities Act. Except as
otherwise stated, the Registrant believes that the issuance of such securities
was exempt from registration pursuant to Section 4(2) of the Securities Act as
transactions not involving a public offering. The purchasers in such private
offerings represented their intention to acquire the securities for investment
only and not with a view to the distribution thereof and appropriate legends
were affixed to the stock certificates issued in such transactions. All
purchasers had adequate access, through their employment or other
relationships, to sufficient information about the Registrant to make an
informed investment decision. No underwriter was employed with respect to any
such sales.     
 
  Unless otherwise stated, no underwriters or placement agents were used in
connection with any of the issuances of securities described below.
   
  During 1995, the Registrant issued 175,000 shares of Common Stock to certain
directors, officers and key employees of the Registrant and consultants and
advisors who have rendered bona fide services to the Registrant not in
connection with the issuance of securities in a capital-raising transaction,
pursuant to its Stock Bonus Plan. The Combined Company believes that such
issuances were exempt from Registration pursuant to Rule 701 and Section 3(b)
of the Securities Act.     
   
  From 1995 to the present, the Registrant has granted options to purchase
1,108,800 shares of Common Stock to certain directors, officers and key
employees of the Registrant and consultants and advisors who have rendered
bona fide services to the Registrant not in connection with the issuance of
securities in a capital-raising transaction, pursuant to its Non-Qualified
Stock Option Plan (the "Plan"). The Combined Company believes that such
issuances were exempt from Registration pursuant to Rule 701 and Section 3(b)
of the Securities Act.     
   
  From March 1995 through June 1995, the Registrant issued an aggregate of
1,091,500 shares of Common Stock to accredited investors as defined under
Regulation D of the Securities Act ("Accredited Investors") at a price of $.50
per share.     
   
  On July 1, 1995, the Registrant granted options for 600,000 shares to two
employees who rendered bona fide services to the Registrant not in connection
with the issuance of securities in a capital-raising transaction. The Combined
Company believes that such issuances were exempt from Registration pursuant to
Rule 701 and Section 3(b) of the Securities Act.     
   
  On September 14, 1995, the Registrant issued 818,774 shares of the Common
Stock to Redden Dynamics Corporation ("Redden") pursuant to a plan of merger
to acquire all of the outstanding shares of capital stock of Redden.

per share, warrants to purchase 50,000 shares of Common Stock are exercisable
at $2.50 per share, and warrants to purchase 50,000 shares of Common Stock are

sophisticated investors. The notes are convertible into shares of Common Stock
at the option of the holder, at a conversion price equal to 90% of the average

share, warrants to purchase 7,000 shares of Common Stock are exercisable at
$.88 per share and warrants to purchase 7,000 shares of Common Stock are
exercisable at $1.38 per share. From January 1997 through January 1998,
557,453 shares of Common Stock were issued upon conversion of approximately
$389,817 principal amount of the notes, and no warrants have been exercised.
    
   
  In February and March 1997, the Registrant issued 15% promissory notes in

exercised.     
   
  From September through December 1997, the Registrant issued 908,641 shares
of Common Stock to 30 investors (29 of whom were Accredited Investors) for
$.55 per share.     
   
  In December 1997, the Registrant issued Bridge Notes in the aggregate
principal amount of $2,840,000 to 17 Accredited Investors. Upon the closing of
this Offering, each investor will receive 4,000 shares of Common Stock for

of $10.00 per share. The Representative acted as placement agent in the

ITEM 17. UNDERTAKINGS.     
 
  (a) Rule 415 Offering. The Registrant hereby undertakes that it will:
 
    (1) File, during any period in which it offers or sells securities, a
  post-effective amendment to this Registration Statement to:
 
      (i)   Include any prospectus required by Section 10(a)(3) of the
    Securities Act;
 
      (ii)  Reflect in the prospectus any facts or events which,
    individually or together, represent a fundamental change in the
    information in the Registration Statement; and
 
      (iii) Include any additional or changed material information on the
    plan of distribution.
 
    (2) For determining liability under the Securities Act, treat each post-
  effective amendment as a new registration statement of the securities
  offered, and the offering of the securities at that time to be the initial
  bona fide offering.
 
    (3) File a post-effective amendment to remove from registration any of
  the securities that remain unsold at the end of the offering.
 
  (d) Prompt Delivery. The Registrant undertakes to provide to the
Underwriters at the closing specified in the Underwriting Agreement
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.
 
  (e) Indemnification. Insofar as indemnification for liabilities arising
under the Securities Act may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable.
 
                                     II-5
<PAGE>
 
  In the event that a claim for indemnification against such liabilities
(other than the payment by the small business issuer of expenses incurred or
paid by a director, officer or controlling person of the small business issuer
in the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with the securities
being registered, the small business issuer will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.
 
  (f) Rule 430A.
 
  The Registrant hereby undertakes that it will:
 
    (i) For determining any liability under the Securities Act, treat the
  information omitted from the form of Prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of Prospectus filed by the Registrant under Rule 424(b)(1) or (4) or 497(h)
  under the Securities Act as part of this Registration Statement as of the
  time the Commission declared it effective.
 
    (ii) For determining any liability under the Securities Act, treat each
  post-effective amendment that contains a form of Prospectus as a new
  registration statement for the securities offered in the registration
  statement, and that offering of the securities at that time as the initial
  bona fide offering of those securities.

As Representatives of the Several Underwriters
18301 Von Karman, Suite 100
Irvine,  California  92715

Dear Sirs:

     Communication Systems International, Inc., a Colorado corporation (the
"Company"), hereby confirms its agreement with the several underwriters named in
Schedule 1 hereto (the "Underwriters"), for whom you have been duly authorized
to act as representatives (in such capacity, the "Representatives"), as set
forth below.  If you are the only Underwriters, all references herein to the
Representatives shall be deemed to be to the Underwriters.

     1.  SECURITIES.  Subject to the terms and conditions herein contained, the
         ----------                                                            
Company proposes to sell to the several Underwriters an aggregate of
shares (the "Firm Securities") of the Company's Common Stock, no par value per
share (the "Common Stock").  The Company also proposes to sell to the several
Underwriters not more than                  additional shares of Common Stock
(15% of the number of shares constituting the Firm Securities) if requested by
the Representatives as provided in Section 3 of this Agreement.  Any and all
shares of Common Stock to be purchased by the Underwriters pursuant to such
option are referred to herein as the "Option Securities."  The Firm Securities
and any Option Securities are collectively referred to herein as the
"Securities."

     2.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.
         --------------------------------------------- 

         (a)   The Company represents and warrants to, and agrees with, each of
     the several Underwriters that:

               (i) a registration statement on Form S-1 (File No. 333-47045)
          with respect to the Securities, including a prospectus subject to
          completion, has been filed by the Company with the Securities and
          Exchange Commission (the "Commission") under the Securities Act of
          1933, as amended (the "Act"), and one or more amendments to

____________________
     /1/Plus an option to purchase up to           additional shares to cover 
over-allotments, if any.
<PAGE>
 
          such registration statement may have been so filed.  After the
          execution of this Agreement, the Company will file with the Commission
          either (A) if such registration statement, as it may have been
          amended, has been declared by the Commission to be effective under the
          Act, a prospectus in the form most recently included in an amendment
          to such registration statement (or, if no such amendment shall have
          been filed, in such registration statement), with such changes or
          insertions as are required by Rule 430A under the Act or permitted by
          Rule 424(b) under the Act, and as have been provided to and approved
          by the Representatives prior to the execution of this Agreement, or
          (B) if such registration statement, as it may have been amended, has
          not been declared by the Commission to be effective under the Act, an
          amendment to such registration statement, including a form of
          prospectus, a copy of which amendment has been furnished to and
          approved by the Representatives prior to the execution of this
          Agreement.  As used in this Agreement, the term "Registration
          Statement" means the registration statement initially filed relating
          to the Securities, as amended at the time when it was or is declared
          effective, including all financial schedules and exhibits thereto and
          including any information omitted therefrom pursuant to Rule 430A
          under the Act and included in the Prospectus (as hereinafter defined);
          the term "Preliminary Prospectus" means each prospectus subject to
          completion filed with such registration statement or any amendment
          thereto (including the prospectus subject to completion, if any,
          included in the Registration Statement or any amendment thereto at the
          time it was or is declared effective); the term "Prospectus" means:
          the prospectus first filed with the Commission pursuant to Rule 424(b)
          under the Act; or if no prospectus is required to be filed pursuant to
          Rule 424(b) under the Act, the prospectus included in the Registration
          Statement.

               (ii) The Commission has not issued or, to the best knowledge of
          the Company, threatened or contemplated any order preventing or
          suspending the use of any Preliminary Prospectus; no stop order
          suspending the sale of the Securities in any jurisdiction has been
          issued and no proceedings for that purpose are pending or, to the best
          knowledge of the Company, threatened or contemplated, and any request
          of the Commission for additional information (to be included in the
          Registration Statement, any Preliminary Prospectus or the Prospectus
          or otherwise) has been complied with.  When the Prospectus or any
          amendment or supplement to the Prospectus is filed with the Commission
          pursuant to Rule 424(b) (or, if the Prospectus or any part thereof or
          such amendment or supplement is not required to be so filed, when the
          Registration Statement or the amendment thereto containing such
          amendment or supplement to the Prospectus was or is declared
          effective) and on the Firm Closing Date and any Option Closing Date
          (both as hereinafter defined), the Prospectus, as amended or
          supplemented at any such time, (A) contained or will contain all
          statements required to be stated therein in accordance with, and
          complied or will comply in all material respects with the requirements
          of, the Act and the rules and regulations of the Commission thereunder
          and (B) did not or will not include any untrue statement of a material
          fact or omit to state any material fact necessary in order to make the
          statements therein, in the light of the circumstances under which they
          were made, not misleading.  The foregoing provisions of this paragraph
          (ii) do not apply to statements or omissions made in the Registration
          Statement or any amendment thereto or the Prospectus or any amendment
          or supplement thereto in

                                      -2-
<PAGE>
 
          reliance upon and in conformity with written information furnished to
          the Company by any Underwriter through the Representatives
          specifically for use therein.

               (iii)  The Company and International Telephone Company, which
          will be a subsidiary of the Company at the Closing Date (the
          "subsidiary") have been duly organized and are validly existing as
          corporations in good standing under the laws of their respective
          jurisdictions of incorporation and are duly qualified to transact
          business as foreign corporations and are in good standing under the
          laws of all other jurisdictions where the ownership or leasing of
          their respective properties or the conduct of their respective
          businesses requires such qualification, except where the failure to be
          so qualified does not result in a material adverse change in the
          condition (financial or otherwise), business, prospects, net worth or
          results of operations of the Company and its subsidiary, taken as a
          whole (a "Material Adverse Effect").

               (iv) The Company and its subsidiary have full power (corporate
          and other) to own or lease their respective properties and conduct
          their respective businesses as described in the Registration Statement
          and the Prospectus (or, if the Prospectus is not in existence, the
          most recent Preliminary Prospectus); the Company has full power
          (corporate and other) and authority to enter into this Agreement and
          to carry out all the terms and provisions hereof to be carried out by
          it; and the Company has full power (corporate and other) and authority
          to execute and deliver the warrants to purchase Common Stock to be
          issued and sold to the Representatives under the terms of the Warrant
          Agreement (as hereinafter defined) in accordance with Section 5(n)
          hereto (the "Representatives' Warrants").

               (v) The issued shares of capital stock of the Company's
          subsidiary have been duly authorized and validly issued, are fully
          paid and nonassessable and are owned beneficially by the Company free
          and clear of any security interests, liens, encumbrances, equities or
          claims, other than the pledge thereof to secure the Mandatory
          Redeemable Convertible Promissory Notes issued in December 1997 (the
          "Bridge Notes").  The Common Stock issuable pursuant to the
          Representatives' Warrants, when issued in accordance with the terms
          thereof, will be duly authorized, validly issued, fully paid and
          nonassessable.  The Representatives' Warrants and the shares of Common
          Stock issuable thereunder were not and will not be issued in violation
          of any preemptive rights of any security holder of the Company.  The
          Company has reserved a sufficient number of shares of Common Stock for
          issuance pursuant to the Representatives' Warrants.  The holders of
          the Common Stock issuable pursuant to the Representatives' Warrants
          will not be subject to personal liability solely by reason of being
          such holders.  The issuance and sale of the Common Stock pursuant to
          the Representatives' Warrants will be made in conformity with the
          applicable registration requirements or exemptions therefrom under
          federal and applicable state securities law.

               (vi) The Company has an authorized, issued and outstanding
          capitalization as set forth in the Prospectus (or, if the Prospectus
          is not in existence, the most recent Preliminary Prospectus).  All of
          the issued shares of capital stock of the Company have been duly
          authorized and validly issued and are fully paid and nonassessable.
          The Firm Securities and the Option Securities have been duly
          authorized and at the

                                      -3-
<PAGE>
 
          Firm Closing Date or the related Option Closing Date (as the case may
          be), after payment therefor in accordance herewith, will be validly
          issued, fully paid and nonassessable.  At the Firm Closing Date or the
          Option Closing Date, no holders of outstanding shares of capital stock
          of the Company will be entitled as such to any preemptive or other
          rights to subscribe for any of the Securities, and no holder of
          securities of the Company has any right which has not been fully
          exercised or waived to require the Company to register the offer or
          sale of any securities owned by such holder under the Act in the
          public offering contemplated by this Agreement.

               (vii)  The capital stock of the Company conforms in all material
          respects to the description thereof contained in the Prospectus (or,
          if the Prospectus is not in existence, the most recent Preliminary
          Prospectus), and this Agreement, the Warrant Agreement and the
          Representatives' Warrants conform in all material respects to the
          descriptions thereof contained in the Prospectus (or, if the
          Prospectus is not in existence, the most recent Preliminary
          Prospectus).

               (viii)  Except as disclosed in the Prospectus (or, if the
          Prospectus is not in existence, the most recent Preliminary
          Prospectus), there are no outstanding (A) securities or obligations of
          the Company or its subsidiary convertible into or exchangeable for any
          capital stock of the Company or its subsidiary, (B) warrants, rights
          or options to subscribe for or purchase from the Company or its
          subsidiary any such capital stock or any such convertible or
          exchangeable securities or obligations, or (C) obligations of the
          Company or its subsidiary to issue any shares of capital stock, any
          such convertible or exchangeable securities or obligations, or any
          such warrants, rights or options.

               (ix) The financial statements and schedules of the Company and
          its subsidiary included in the Registration Statement and the
          Prospectus (or, if the Prospectus is not in existence, the most recent
          Preliminary Prospectus) fairly present in all material respects the
          financial position of the Company and its subsidiary and the results
          of operations and cash flows as of the dates and periods therein
          specified.  Such financial statements and schedules have been prepared
          in accordance with generally accepted accounting principles ("GAAP")
          consistently applied throughout the periods involved (except as
          otherwise noted therein).  The selected financial data set forth under
          the captions "Summary Financial Information" and "Capitalization" in
          the Prospectus (or, if the Prospectus is not in existence, the most
          recent Preliminary Prospectus) fairly present, in accordance with
          GAAP, as applicable, on the basis stated in the Prospectus (or such
          Preliminary Prospectus), the information included therein.  No other
          financial statements or schedules are required to be included in the
          Registration Statement.

               (x) Stockman Kast Ryan & Scruggs, P.C., which has audited the
          financial statements of the Company, and Richard A. Eisner & Company,
          LLP, which has audited the financial statements of the subsidiary and
          delivered their reports with respect to the audited financial
          statements included in the Registration Statement and the Prospectus
          (or, if the Prospectus is not in existence, the most recent
          Preliminary Prospectus), are independent public accountants as
          required by the Act and the applicable rules and regulations
          thereunder.

               (xi) The execution and delivery of this Agreement, the Warrant
          Agreement and the Representatives' Warrants have been duly authorized
          by the Company; this Agreement has been duly executed and delivered by
          the Company and, as of the Closing Date, the Warrant Agreement and the
          Representatives' Warrants will have been duly executed and delivered
          by the Company and this Agreement is, and the Warrant Agreement and
          the Representatives' Warrants when executed and delivered by the
          Company on the Closing Date, and in the case of the Representatives'
          Warrants, paid for by the Representatives, will be the valid and
          binding obligations of the Company, enforceable against the Company in
          accordance with their respective terms, except as such enforceability
          may be limited by the effect of bankruptcy, insolvency,
          reorganization, moratorium and other similar laws relating to rights
          and remedies of creditors or by general equitable principles. The
          information in the Registration Statement and the Prospectus insofar
          as it relates to the Representatives' Warrants, in each case as of the
          date on which the Registration Statement is declared effective by the
          Commission, the Closing Date and any Option Closing Date, is true,
          correct and complete in all material respects.

               (xii)  No legal or governmental proceedings are pending to which
          the Company or its subsidiary is a party or to which the property of
          the Company or its subsidiary is subject that are required to be
          described in the Registration Statement or the Prospectus and are not
          described therein (or, if the Prospectus is not in existence, the most
          recent Preliminary Prospectus), and, to the Company's knowledge, no
          such proceedings have been threatened against the Company or its
          subsidiary or with respect to any of their respective properties; and
          no contract or other document is required to be described in the
          Registration Statement or the Prospectus or to be filed as an exhibit
          to the Registration Statement that is not described therein (or, if
          the Prospectus is not in existence, the most recent Preliminary
          Prospectus) or filed as required.

               (xiii)  The issuance, offering and sale of the Securities to the
          Underwriters by the Company pursuant to this Agreement and of the
          Representatives' Warrants to the Representatives by the Company
          pursuant to the Warrant Agreement; the execution and delivery of this
          Agreement, the Warrant Agreement and the Representatives' Warrants by
          the Company; the compliance by the Company with the provisions of this
          Agreement, the Warrant Agreement and the Representatives' Warrants;
          and the consummation of all transactions contemplated therein do not
          (A) require the consent, approval, authorization, registration or
          qualification of or with any court, government or governmental
          authority, domestic or foreign, except such as have been obtained,
          such as may be required under state securities or blue sky laws, such
          as may be required by the National Association of Securities Dealers,
          Inc. (the "NASD") and, if the Registration Statement filed with
          respect to the Securities (as amended) is not effective under the Act
          as of the time of execution hereof, such as may be required (and shall
          be obtained as provided in this Agreement) under the Act, or (B)
          conflict with or result in a breach or violation of any of the terms
          and provisions of, or constitute a default under, any indenture,
          mortgage, deed of trust, lease or other agreement or instrument to
          which the Company or its subsidiary is a party or by which the Company
          or its subsidiary or any of their respective properties are bound, or
          the charter documents or by-laws of the Company or its subsidiary, or

                                      -5-
<PAGE>
 
          any statute or any judgment, decree, order, rule or regulation of any
          court or other governmental authority or any arbitrator applicable to
          the Company or its subsidiary, which would have a Material Adverse
          Effect.

               (xiv)  Subsequent to the respective dates as of which information
          is given in the Registration Statement and the Prospectus (or, if the
          Prospectus is not in existence, the most recent Preliminary
          Prospectus), neither the Company nor its subsidiary has sustained any
          loss or interference with their respective businesses or properties
          having or resulting in a Material Adverse Effect from fire, flood,
          hurricane, accident or other calamity, whether or not covered by
          insurance, or from any labor dispute or any legal or governmental
          proceeding and there has not been any event, circumstance, or
          development that results in, or that the Company believes would result
          in, a Material Adverse Effect, except in each case as described in the
          Prospectus (or, if the Prospectus is not in existence, the most recent
          Preliminary Prospectus).

               (xv) The Company and its subsidiary have not, directly or
          indirectly (except for the sale of Securities under this Agreement),
          (i) taken any action designed to cause or to result in, or that has
          constituted or which might reasonably be expected to constitute, the
          stabilization or manipulation of the price of any security of the
          Company to facilitate the sale or resale of the Securities or (ii)
          since the filing of the Registration Statement (A) sold, bid for,
          purchased, or paid anyone any compensation for soliciting purchases
          of, the Securities or (B) paid or agreed to pay to any person any
          compensation for soliciting another to purchase any other securities
          of the Company.

               (xvi) (a) The Company and its subsidiary possess all
          certificates, authorizations and permits issued by the appropriate
          federal, state or foreign regulatory authorities necessary to conduct
          their respective businesses except where the failure to possess any
          such item would not have a Material Adverse Effect, and (b) neither
          the Company nor its subsidiary has received any notice of proceedings
          relating to the revocation or modification of any such certificate,
          authorization or permit that, singly or in the aggregate, if the
          subject of an unfavorable decision, ruling or finding, would have a
          Material Adverse Effect, except as described in the Prospectus (or, if
          the Prospectus is not in existence, the most recent Preliminary
          Prospectus).

               (xvii)  The Company is not an investment company under the
          Investment Company Act of 1940, as amended (the "1940 Act"), and this
          transaction will not cause the Company to become an investment company
          subject to registration under the 1940 Act.

               (xviii)  The Company and its subsidiary have filed all foreign,
          federal, state and local tax returns that are required to be filed or
          has requested extensions thereof (except in any case in which the
          failure so to file would not have a Material Adverse Effect) and has
          paid all taxes required to be paid by them and any other assessment,
          fine or penalty levied against them, to the extent that any of the
          foregoing is due and payable, except for any such assessment, fine or
          penalty that is currently being

                                      -6-
<PAGE>
 
          contested in good faith or as described in or contemplated by the
          Prospectus (or, if the Prospectus is not in existence, the most recent
          Preliminary Prospectus).

               (xix)  Except for the shares of capital stock of the subsidiary
          owned by the Company, and except with respect to the merger pending
          with GlobalTel Resources, Inc. ("GlobalTel") neither the Company nor
          its subsidiary owns any shares of stock or any other equity securities
          of any corporation or has any equity interest in any firm,
          partnership, association or other entity.

               (xx) The books, records and accounts of the Company and its
          subsidiary accurately and fairly reflect, in reasonable detail, the
          transactions in and dispositions of the assets of the Company and its
          subsidiary, respectively.  The Company and its subsidiary maintain a
          system of internal accounting controls sufficient to provide
          reasonable assurance that (A) transactions are executed in accordance
          with management's general or specific authorizations; (B) transactions
          are recorded as necessary to permit preparation of financial
          statements in conformity with generally accepted accounting principles
          and to maintain asset accountability; (C) access to assets is
          permitted only in accordance with management's general or specific
          authorization; and (D) the recorded accountability for assets is
          compared with the existing assets at reasonable intervals and
          appropriate action is taken with respect to any differences.

               (xxi)  Except as described in the Registration Statement and the
          Prospectus (or, if the Prospectus is not in existence, the most recent
          Preliminary Prospectus), no default exists and no event has occurred
          that, with notice or lapse of time or both, would constitute a
          default, in the due performance and observance of any term, covenant
          or condition of any contract, indenture, mortgage, deed of trust,
          lease or other agreement or instrument to which the Company or its
          subsidiary is a party or by which the Company or its subsidiary or any
          of their respective properties is bound or may be affected, in any
          respect that would have a Material Adverse Effect.  The agreements to
          which the Company or its subsidiary is a party described in the
          Registration Statement are valid agreements, enforceable by the
          Company or its subsidiary, except as the enforcement thereof may be
          limited by applicable bankruptcy, insolvency, reorganization,
          moratorium or other similar laws relating to or affecting creditors'
          rights generally or by general equitable principles and, to the best
          of the Company's knowledge, the other contracting party or parties
          thereto are not in material breach or material default under any of
          such agreements.

               (xxii)  The Company and the subsidiary have not distributed and,
          prior to the later of (A) the Firm Closing Date or any Option Closing
          Date and (B) the completion of the distribution of the Securities,
          will not distribute any written offering material in connection with
          the offering and sale of the Securities other than the Registration
          Statement or any amendment thereto, any Preliminary Prospectus, the
          Prospectus or any amendment or supplement thereto, or other materials,
          if any, permitted by the Act.

               (xxiii)  The Company and its subsidiary have good and marketable
          title to all personal property owned by each of them, in each case
          free and clear of any security

                                      -7-
<PAGE>
 
          interests, liens, encumbrances, equities, claims and other defects,
          except for those relating to debts of the Company or its subsidiary
          described in the Registration Statement and the Prospectus (or, if the
          Prospectus is not in existence, the most recent Preliminary
          Prospectus) and those that do not interfere with the use made or
          proposed to be made of such property by the Company or its subsidiary,
          and any real property and buildings held under lease by the Company or
          its subsidiary are held under valid, subsisting and enforceable leases
          (except as enforceability may be limited by the effect of bankruptcy,
          insolvency, reorganization, moratorium and other similar laws relating
          to rights and remedies of creditors or by general equitable
          principles), with such exceptions as are not material and do not
          interfere with the use made or proposed to be made of such property
          and buildings by the Company or its subsidiary, in each case except as
          described in or contemplated by the Prospectus (or, if the Prospectus
          is not in existence, the most recent Preliminary Prospectus).  The
          Company and its subsidiary own or lease all such properties as are
          necessary to their respective operations as now conducted and as
          described in the Registration Statement and the Prospectus (or, if the
          Prospectus is not in existence, the most recent Preliminary
          Prospectus).

               (xxiv)  No labor dispute with the employees of the Company or its
          subsidiary exists or to the Company's knowledge, is threatened or
          imminent that could result in a Material Adverse Effect, except as
          described in or contemplated by the Prospectus (or, if the Prospectus
          is not in existence, the most recent Preliminary Prospectus), and the
          Company is not aware of an existing, imminent or threatened labor
          disturbance by the employees of any principal suppliers,
          manufacturers, contractors or others that could result in a Material
          Adverse Effect, except as described in or contemplated by the
          Prospectus (or, if the Prospectus is not in existence, the most recent
          Preliminary Prospectus).

               (xxv)  The Company and its subsidiary own or possess all material
          trademarks, service marks, trade names, licenses, copyrights and
          proprietary or other confidential information currently employed by
          them in connection with their respective businesses, and neither the
          Company nor its subsidiary has received any notice of infringement of
          or conflict with asserted rights of any third party with respect to
          any of the foregoing which, singly or in the aggregate, if the subject
          of unfavorable decisions, rulings or findings, would have a Material
          Adverse Effect, except as described in the Prospectus (or, if the
          Prospectus is not in existence, the most recent Preliminary
          Prospectus).  The description of the Company's agreements with its
          independent sales agents and carriers and resellers, and the
          agreements relating to its strategic relationships, contained in the
          Registration Statement and the Prospectus (or, if the Prospectus is
          not in existence, the most recent Preliminary Prospectus), are true
          and complete in all material respects.  All such agreements are valid,
          binding and in full force and effect and neither the Company nor its
          subsidiary is, or has received any notice that it is, in default (or
          with the giving of notice or lapse of time or both, would be in
          default) under any such agreements.

               (xxvi)  The Company and its subsidiary are insured by insurers of
          recognized financial responsibility against such losses and risks and
          in such amounts as are prudent and customary in the businesses in
          which they are engaged; and neither the

                                      -8-
<PAGE>
 
          Company nor its subsidiary has any reason to believe that it will not
          be able to renew its existing insurance coverage as and when such
          coverage expires or to obtain similar coverage from similar insurers
          as may be necessary to continue its business at a cost that would not
          have a Material Adverse Effect, except as described in or contemplated
          by the Prospectus (or, if the Prospectus is not in existence, the most
          recent Preliminary Prospectus).

               (xxvii)  The Common Stock will be registered pursuant to Section
          12(g) of the Securities Exchange Act of 1934, as amended (the
          "Exchange Act"), on the date hereof and is traded on the OTC Bulletin
          Board and, upon notice of issuance, the Securities will be traded on
          the Nasdaq SmallCap Market, and the Company has taken no action
          designed to, or likely to have the effect of, terminating the
          registration of the Common Stock under the Exchange Act or delisting
          the Common Stock from the OTC Bulletin Board or that could in the
          future cause the Common Stock to be delisted from the Nasdaq SmallCap
          Market, nor has the Company received any notification that the
          Commission or The Nasdaq Stock Market, Inc. is contemplating
          terminating such registration or listing.

               (xxviii)  Neither the Company nor the subsidiary has at any time
          during the last five (5) years (A) made any unlawful contribution to
          any candidate for foreign office or failed to disclose fully any
          contribution in violation of law, or (B) made any payment to any
          federal or state governmental officer or official, or other person
          charged with similar public or quasi-public duties, other than
          payments required or permitted by the laws of the United States or any
          jurisdiction thereof.

               (xxix)  Any pro forma financial or other information and related
          notes included in the Registration Statement, each Preliminary
          Prospectus and the Prospectus comply (or, if the Prospectus has not
          been filed with the Commission, as to the Prospectus, will comply) in
          all material respects with the requirements of the Act and the rules
          and regulations of the Commission thereunder and present fairly in all
          material respects the pro forma information shown, as of the dates and
          for the periods covered by such pro forma information.  Such pro forma
          information, including any related notes and schedules, has been
          prepared on a basis consistent with the historical financial
          statements and other historical information, as applicable, included
          in the Registration Statement, the Preliminary Prospectus and the
          Prospectus, except for the pro forma adjustments specified therein,
          and give effect to assumptions made on a reasonable basis to give
          effect to historical and, if applicable, proposed transactions
          described in the Registration Statement, each Preliminary Prospectus
          and the Prospectus.

               (xxx)  Except as set forth in the Prospectus (or, if the
          Prospectus is not in existence, the most recent Preliminary
          Prospectus), there are no outstanding loans, advances or guaranties of
          indebtedness by the Company or its subsidiary to or for the benefit of
          any of (i) its "affiliates," as such term is defined in the Act and
          the rules and regulations thereof or (ii) any of the members of the
          families of any of them.

               (xxxi)  The Company and its subsidiary have no liability,
          absolute or contingent, relating to:  (A) public health or safety; (B)
          worker health or safety; (C)

                                      -9-
<PAGE>
 
          product defect or warranty (except, as to product defect or warranty,
          as is disclosed in the Registration Statement and Prospectus (or, if
          the Prospectus is not in existence, the most recent Preliminary
          Prospectus)); or (D) pollution, damage to or protection of the
          environment, including, without limitation, relating to damage to
          natural resources, emissions, discharges, releases or threatened
          releases of hazardous materials into the environment (including,
          further without limitation, ambient air, surface water, groundwater,
          land surface or subsurface strata) or otherwise relating to the
          manufacture, processing, use, treatment, storage, generation,
          disposal, transport or handling of any hazardous materials, except any
          such liability that would not result in a material adverse effect.
          The Company is not aware of the date hereof of the existence of any
          such liability, absolute or contingent, of the type discussed above.
          As used herein, "hazardous material" includes chemical substances,
          wastes, pollutants, contaminants, hazardous or toxic substances,
          constituents, materials or wastes, whether solid, gaseous or liquid in
          nature.

               (xxxii)  Neither the Company nor its subsidiary is presently
          doing business with the government of Cuba or with any person or
          affiliate located in Cuba.

          (b) Any certificate signed by any officer of the Company and delivered
     to the Representatives or to counsel for the Representatives pursuant to
     this Agreement shall be deemed a representation and warranty by the Company
     to each Underwriter, as to the matters covered thereby.

          (c) The Representatives shall receive, at the Firm Closing Date and
     any Option Closing Date, representations and warranties of GlobalTel which
     shall be identical in form and substance to the representations and
     warranties of the Company set forth in Section 2(a) above.  Such
     representations and warranties shall be set forth in a certificate by the
     executive officers of GlobalTel and delivered to the Representatives or to
     counsel for the Representatives.

     3.   PURCHASE, SALE AND DELIVERY OF THE SECURITIES.
          --------------------------------------------- 

          (a) On the basis of the representations, warranties, agreements and
     covenants herein contained and subject to the terms and conditions herein
     set forth, (i) the Company agrees to issue and sell               Firm
     Securities, (ii) each of the Underwriters agrees to purchase from the
     Company at a purchase price of [$           ] per share, an aggregate
     number of Firm Securities set forth opposite the name of such Underwriter
     in Schedule 1 hereto.  One or more certificates in definitive form for the
     Firm Securities that the several Underwriters have agreed to purchase
     hereunder from the Company, in such denomination or denominations and
     registered in such name or names as the Representatives request upon notice
     to the Company at least 48 hours prior to the Firm Closing Date, shall be
     delivered by or on behalf of the Company to the Representatives for the
     respective accounts of the Underwriters, against payment by or on behalf of
     the Underwriters of the aggregate purchase price therefor by wire transfer
     in same day funds (the "Wired Funds") to the account of the Company.  Such
     delivery of and payment for the Firm Securities shall be made at the
     offices of Cruttenden Roth Incorporated, 18301 Von Karman, Suite 100,
     Irvine, California 92715, at 6:30 a.m., Pacific time, on June _____, 1998,
     or at such other place, time or date as the Representatives and the Company
     may agree upon or as the Representatives may determine

                                      -10-
<PAGE>
 
     pursuant to Section 9 hereof, such time and date of delivery against
     payment being herein referred to as the "Firm Closing Date."  The Company
     will make such certificate or certificates for the Firm Securities
     available for checking and packaging by the Representatives at the offices
     of the Company's transfer agent or registrar at least 24 hours prior to the
     Firm Closing Date or, if available, will coordinate the transfer of the
     Firm Securities to the Underwriters through the book-entry facilities of
     the Depository Trust Company.

          (b) For the sole purpose of covering any over-allotments in connection
     with the distribution and sale of the Firm Securities as contemplated by
     the Prospectus, on the basis of the covenants and agreements of the
     Underwriters contained in this Agreement and subject to the terms and
     conditions set forth in this Agreement, the Company hereby grants to the
     several Underwriters an option to purchase the Option Securities.  The
     purchase price to be paid for any Option Securities shall be the same price
     per share as the price per share for the Firm Securities set forth above in
     paragraph (a) of this Section 3.  The option granted hereby may be
     exercised as to all or any part of the Option Securities from time to time
     within 45 days after the date of the Prospectus (or, if such 45th day shall
     be a Saturday or Sunday or a holiday, on the next business day thereafter
     when the Nasdaq SmallCap Market is open).  The Underwriters shall not be
     under any obligation to purchase any of the Option Securities prior to the
     exercise of such option.  The Representatives may from time to time
     exercise the option granted hereby by giving notice in writing or by
     telephone (confirmed within 24 hours in writing) to the Company setting
     forth the aggregate number of Option Securities as to which the several
     Underwriters are then exercising the option and the date and time for
     delivery of and payment for such Option Securities.  Any such date of
     delivery shall be determined by the Representatives but shall not be
     earlier than two business days or later than five business days after such
     exercise of the option and, in any event, shall not be earlier than the
     Firm Closing Date.  The time and date set forth in such notice, or such
     other time on such other date as the Representatives and the Company may
     agree upon or as the Representatives may determine pursuant to Section 9
     hereof, is herein called the "Option Closing Date" with respect to such
     Option Securities.  Upon exercise of the option as provided herein, the
     Company shall become obligated to sell to each of the several Underwriters,
     and, subject to the terms and conditions herein set forth, each of the
     Underwriters (severally and not jointly) shall become obligated to purchase
     from the Company, the same percentage of the total number of the Option
     Securities as to which the several Underwriters are then exercising the
     option as such Underwriter is obligated to purchase of the aggregate number
     of Firm Securities, as adjusted by the Representatives in such manner as it
     deems advisable to avoid fractional shares.  If the option is exercised as
     to all or any portion of the Option Securities, one or more certificates in
     definitive form for such Option Securities, and payment therefor, shall be
     delivered on the related Option Closing Date in the manner, and upon the
     terms and conditions, set forth in paragraph (a) of this Section 3, except
     that reference therein to the Firm Securities and the Firm Closing Date
     shall be deemed, for purposes of this paragraph 3(b), to refer to such
     Option Securities and Option Closing Date, respectively.

          (c) It is understood that you, individually and not as the
     Representatives, may (but shall not be obligated to) make payment on behalf
     of any Underwriter or Underwriters for any of the Securities to be
     purchased by such Underwriter or Underwriters.  No such

                                      -11-
<PAGE>
 
     payment shall relieve such Underwriter or Underwriters from any of its or
     their obligations hereunder.

          (d) The Company hereby acknowledges that the wire transfer by or on
     behalf of the Underwriters of the purchase price for any Securities does
     not constitute closing of a purchase and sale of the Securities.  Only
     execution and delivery of a receipt (by facsimile or otherwise) for the
     Securities by the Underwriters indicates completion of the closing of a
     purchase of the Securities from the Company.  Furthermore, in the event
     that the Underwriters wire funds to the Company prior to the completion of
     the closing of a purchase of Securities, the Company hereby acknowledges
     that until the Underwriters execute and deliver a receipt for the
     Securities, by facsimile or otherwise, the Company will not be entitled to
     the wired funds and shall return the wired funds received by it to the
     Underwriters as soon as practicable (by wire transfer of same-day funds)
     upon demand.  In the event that the closing of a purchase of Securities is
     not completed and the wired funds are not returned by the Company to the
     Underwriters on the same day the wired funds were received by the Company,
     the Company agrees to pay to the Underwriters in respect of each day the
     wired funds are not returned by it, in same-day funds, interest at the
     Prime Rate (as defined in Section 8(a)) on the date hereof on the amount of
     such wire funds received by them.

          (e) At the Firm Closing Date and any Option Closing Date, the Company
     shall pay to the Representatives a non-accountable expense allowance equal
     to 2 1/2% of the gross proceeds from the sale of the Securities.

     4.   OFFERING BY THE UNDERWRITERS.  Upon your authorization of the release
          ----------------------------                                         
of the Firm Securities, the several Underwriters propose to offer the Firm
Securities for sale to the public upon the terms set forth in the Prospectus.

     5.   COVENANTS OF THE COMPANY.  The Company covenants and agrees with each
          ------------------------                                             
of the Underwriters that:

          (a) The Company will use its best efforts to cause the Registration
     Statement, if not effective at the time of execution of this Agreement, to
     become effective as promptly as possible.  If required, the Company will
     file the Prospectus and any amendment or supplement thereto with the
     Commission in the manner and within the time period required by Rule
     424(b) under the Act.  During any time when a prospectus relating to the
     Securities is required to be delivered under the Act, the Company (i) will
     comply with all requirements imposed upon it by the Act and the rules and
     regulations of the Commission thereunder to the extent necessary to permit
     the continuance of sales of or dealings in the Securities in accordance
     with the provisions hereof and of the Prospectus, as then amended or
     supplemented, and (ii) will not file with the Commission the Prospectus or
     the amendment referred to in the second sentence of Section 2(a)(i) hereof,
     any amendment or supplement to such Prospectus, or any amendment to the
     Registration Statement of which the Representatives shall not previously
     have been advised and furnished with a copy for a reasonable period of time
     prior to the proposed filing and as to which filing the Representatives
     shall not have given their consent.  The Company will prepare and file with
     the Commission, in accordance with the rules and regulations of the
     Commission, promptly upon request by the Representatives or counsel for the
     Representatives, any amendments to the Registration Statement or amendments
     or supplements to the Prospectus that may be deemed necessary or advisable
     in connection with the distribution of the Securities by the several
     Underwriters, and will use its best efforts to cause any such amendment to
     the Registration Statement to be declared effective by the Commission as
     promptly as possible.

                                      -12-
<PAGE>
 
     The Company will advise the Representatives, promptly after receiving
     notice thereof, of the time when the Registration Statement or any
     amendment thereto has been filed or declared effective or the Prospectus or
     any amendment or supplement thereto has been filed and will provide to the
     Representatives copies of each such filing.

          (b) The Company will advise the Representatives, promptly after
     receiving notice or obtaining knowledge thereof, of (i) the issuance by the
     Commission of any stop order suspending the effectiveness of the
     Registration Statement or any amendment thereto or any order preventing or
     suspending the use of any Preliminary Prospectus or the Prospectus or any
     amendment or supplement thereto, (ii) the suspension of the qualification
     of the Securities for offering or sale in any jurisdiction, (iii) the
     institution, threatening or contemplation of any proceeding for any such
     purpose, or (iv) any request made by the Commission for amending the
     Registration Statement, for amending or supplementing the Prospectus or for
     additional information.  The Company will use its best efforts to prevent
     the issuance of any such stop order and, if any such stop order is issued,
     to obtain the withdrawal thereof as promptly as possible.

          (c) The Company will arrange for the qualification of the Securities
     for offering and sale under the securities or blue sky laws of such
     jurisdictions as the Representatives may designate and will continue such
     qualifications in effect for as long as may be necessary to complete the
     distribution of the Securities; provided, however, that in connection
     therewith the Company shall not be required to qualify as a foreign
     corporation or to execute a general consent to service of process in any
     jurisdiction.  If, after the public offering of the Securities by the
     Underwriters and during such period, the Underwriters propose to vary the
     terms of offering thereof by reason of changes in general market conditions
     or otherwise, the Representatives will advise the Company in writing of the
     proposed variation and if, in the opinion either of counsel for the Company
     or counsel for the Representatives, such proposed variation requires that
     the Prospectus be supplemented or amended, the Company will forthwith
     prepare and file with the Commission a supplement to the Prospectus or an
     amended Prospectus setting forth such variation.  The Company authorizes
     the Underwriters and all dealers to whom any of the Securities may be sold
     by the Underwriters to use the Prospectus, as from time to time so amended
     or supplemented, in connection with the sale of the Securities in
     accordance with the applicable provisions of the Act and the rules and
     regulations thereunder for such period.

          (d) If, at any time prior to the later of (i) the final date when a
     prospectus relating to the Securities is required to be delivered under the
     Act or (ii) the Option Closing Date, any event occurs as a result of which
     the Prospectus, as then amended or supplemented, would include any untrue
     statement of a material fact or omit to state a material fact necessary in
     order to make the statements therein, in the light of the circumstances

          authorizations relating to environmental laws.

               (xxiii) at the Closing Date and upon payment of the consideration
          set forth in the Registration Statement, the Company shall have
          purchased all of the outstanding common stock of the subsidiary, and
          shall have received good title to such shares of common stock of the
          subsidiary , free and clear of all liens, security interests, pledges,
          charges, encumbrances, shareholders' agreements and voting trusts.
          Each outstanding share of common stock of the subsidiary is validly
          authorized, validly issued, fully paid and nonassessable, with no
          personal liability attaching to the ownership thereof, and has not
          been issued and is not owned or held in violation of any preemptive
          right of shareholders. There is no commitment, plan or arrangement to
          issue, and no outstanding option, warrant and or other right for the
          issuance of any share of capital stock of the subsidiary or any other
          security or other instrument which by its terms is convertible into,
          exercisable for, or exchangeable for capital stock of the subsidiary,
          except as is properly described in the Prospectus.

Such counsel shall also state that such counsel has participated in conferences
with officers and other representatives of the Company, the independent public
accountants of the Company and the subsidiary, the Representatives and counsel
to the Representatives, at which conferences the contents of the Registration
Statement and the Prospectus and related matters were discussed and, although
such counsel has not undertaken to investigate or verify independently and does
not assume any responsibility for factual statements contained in the
Registration Statement and Prospectus (except as otherwise expressly set forth
herein), on the basis of the foregoing they have no reason to believe that the
Registration Statement, as of its effective date, contained any untrue statement
of a material fact or omitted to state any material fact required to be stated
therein or necessary to make the statements therein not misleading or that the
Prospectus, as of its date or the date of such opinion, contained or contains
any untrue statement of a material fact or omitted or omits to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading (except such counsel
need express no view as to the financial statements and notes thereto, schedules
and reports thereon, and other financial data included in the Registration
Statement or Prospectus).

In rendering any such opinion, such counsel may rely, as to matters of fact, to
the extent such counsel deems proper, on certificates or opinions of responsible
officers of the Company and public officials, and may limit its opinions to the
laws of the United States of America and the States of Colorado and Delaware, as
appropriate.

References to the Registration Statement and the Prospectus in this paragraph
(b) shall include any amendment or supplement thereto at the date of such
opinion.

          (c) At the Firm Closing Date, you shall have received the favorable
     opinion of Haligman & Lottner, P.C., telecommunications counsel for the
     Company, dated the date of delivery, addressed to you, and in form and
     scope satisfactory to your counsel, to the effect that:

               i.  Each of the Company and its subsidiary is in compliance in
          all material respects with all applicable telecommunications-related
          rules and regulations of the United States and their respective state
          of incorporation, compliance with which is necessary to their business
          as currently conducted, including with respect

                                      -20-
<PAGE>
 
          to rules, regulations and tariffs promulgated by the Federal
          Communications Commission;

               ii.  To the best knowledge of such counsel after review of the
          Company's and the subsidiary's operations, each of the Company and its
          subsidiary is in compliance in all material respects with applicable
          telecommunications-related rules and regulations of foreign countries
          in which the Company and its subsidiary currently operate, including
          specifically the countries of Argentina, Brazil, Italy, Lebanon, South
          Africa and South Korea;

               iii.  The statements of international or federal law or
          regulations contained under the captions "Risk Factors" and "Business
          - Regulation" and other references in the Registration Statement and
          Prospectus to telecommunications regulatory matters (collectively, the
          "Regulatory Portion") are, in all material respects, correct and
          accurate statements or summaries of applicable international, federal
          and state law and regulation, subject to the qualifications set forth
          therein; and

               iv.  The Regulatory Portion of the Registration Statement and the
          Prospectus, at the time the Registration Statement became effective
          and at the Firm Closing Date, did not contain any untrue statement of
          a material fact, or omit to state any material fact required to be
          stated therein or necessary to make the statements therein, in light
          of the circumstances under which they were made, not misleading.

          (d) The Representatives shall have received from Stockman Kast Ryan &
     Scruggs, P.C. and Richard A. Eisner & Company, LLP, letters dated,
     respectively, the date hereof and the Firm Closing Date, in form and
     substance satisfactory to the Representatives, to the effect that:

               (i) they are independent accountants with respect to the Company
          and its subsidiary, respectively, within the meaning of the Act and
          the applicable rules and regulations thereunder;

               (ii) in their opinion, the audited financial statements and the
          as adjusted financial data examined by them and included in the
          Registration Statement and the Prospectus comply in form in all
          material respects with the applicable accounting requirements of the
          Act and the related published rules and regulations;

               (iii)  on the basis of carrying out certain specified procedures
          (which do not constitute an examination made in accordance with
          generally accepted auditing standards) that would not necessarily
          reveal matters of significance with respect to the comments set forth
          in this paragraph (iii), a reading of the minute books of the
          shareholders, the board of directors and any committees thereof of the
          Company and its subsidiary, and inquiries of certain officials of the
          Company and its subsidiary who have responsibility for financial and
          accounting matters, nothing came to their attention that caused them
          to believe that at a specific date not more than five business days
          prior to the date of such letter, there were any changes in the
          capital stock or total debt of the Company and its subsidiary or any
          decreases in total assets or shareholders' equity of the Company and
          its subsidiary, in each case compared

                                      -21-
<PAGE>
 
          with amounts shown on the latest balance sheet included in the
          Registration Statement and the Prospectus, or for the period from
          April 30, 1997 or October 31, 1997 to such specified date there were
          any decreases, as compared with the same period in the prior year, in
          total revenue, net loss or net loss per share, respectively, of the
          Company and its subsidiary, except in all instances for changes,
          decreases or increases set forth in such letters;

               (iv) they have carried out certain specified procedures, not
          constituting an audit, with respect to certain amounts, percentages
          and financial information that are derived from the general accounting
          records of the Company and its subsidiary and are included in the
          Registration Statement and the Prospectus, and have compared such
          amounts, percentages and financial information with such records of
          the Company and its subsidiary and with information derived from such
          records and have found them to be in agreement, excluding any
          questions of legal interpretation; and

               (v) their review of the system of internal controls of the
          Company and its subsidiary, to the extent they deemed necessary in
          establishing the scope of their examination of the Company's financial
          statements as of April 30, 1997 or October 31, 1997 did not disclose
          any weaknesses in internal controls that they considered to be
          material weaknesses.

               In the event that the letters referred to above set forth any
          such changes, decreases or increases which, in the reasonable
          discretion of the Representatives, are likely to result in a Material
          Adverse Effect, it shall be a further condition to the obligations of
          the Underwriters that such letters shall be accompanied by a written
          explanation of the Company as to the significance thereof, unless the
          Representatives deem such explanation unnecessary.

               References to the Registration Statement and the Prospectus in
          this paragraph (c) with respect to either letter referred to above
          shall include any amendment or supplement thereto by the date of such
          letter.

          (e) The Representatives shall have received a certificate, dated the
     Firm Closing Date, of Ronald P. Erickson, Robert A. Spade and Patrick R.
     Scanlon, in their capacities as Chairman of the Board, Chief Executive
     Officer and President, respectively, of the Company to the effect that:

               (i) the representations and warranties of the Company in this
          Agreement are true and correct as if made on and as of the Firm
          Closing Date; the Registration Statement, as amended as of the Firm
          Closing Date, does not include any untrue statement of a material fact
          or omit to state any material fact necessary to make the statements
          therein not misleading, and the Prospectus, as amended or supplemented
          as of the Firm Closing Date, does not include any untrue statement of
          a material fact or omit to state any material fact necessary in order
          to make the statements therein, in the light of the circumstances
          under which they were made, not misleading; and the Company has
          performed all covenants and agreements and satisfied all conditions on
          its part to be performed or satisfied at or prior to the Firm Closing
          Date;

                                      -22-
<PAGE>
 
               (ii) no stop order suspending the effectiveness of the
          Registration Statement or any amendment thereto has been issued, and
          no proceedings for that purpose have been instituted or, to the best
          of the Company's knowledge, threatened or are contemplated by the
          Commission; and

               (iii)  subsequent to the respective dates as of which information
          is given in the Registration Statement and the Prospectus, neither the
          Company nor its subsidiary has sustained any loss or interference with
          their respective businesses or properties having or resulting in a
          Material Adverse Effect from fire, flood, hurricane, accident or other
          calamity, whether or not covered by insurance, or from any labor
          dispute or any legal or governmental proceeding, and there has not
          been any event, circumstance, or development that results in, or that
          the Company reasonably believes will result in, a Material Adverse
          Effect, except in each case as described in or contemplated by the
          Prospectus (exclusive of any amendment or supplement thereto).

          (f) The Representatives shall have received from each officer and
     director of the Company and the persons and entities listed in Schedule 3
     an agreement to the effect that such person or entity will not, except to
     the extent otherwise specifically permitted by the terms of each such
     person's or entity's agreement, directly or indirectly, without the prior
     written consent of the Representatives, offer, sell, offer to sell,
     contract to sell, pledge, grant any option to purchase or otherwise sell or
     dispose (or announce any offer, sale, offer of sale, contract of sale,
     pledge, grant of an option to purchase or other sale or disposition) of any
     shares of Common Stock or any securities convertible into, or exchangeable
     or exercisable for, shares of Common Stock for a period of 12 months after
     the date of this Agreement, without the Representatives' prior written
     consent, which consent shall not be unreasonably withheld; provided,
     however, that intra-family transfers or transfers to trust for estate
     planning purposes shall not be so restricted.

          (g) On or before the Firm Closing Date, the Representatives and their
     counsel shall have received such further certificates, documents or other
     information as they may have reasonably requested from the Company.

          (h) Upon consummation of the offering of the Securities, the
     Securities shall have approved for trading, on notice of issuance, on the
     Nasdaq SmallCap Market.

          (i) The Representatives shall have received an opinion, dated the Firm
     Closing Date, of Berliner Zisser Walter & Gallegos, P.C., counsel for the
     Representatives, with respect to the issuance and sale of the Firm
     Securities, the Registration Statement and Prospectus, and such other
     related matters as the Representatives may reasonably require, and the
     Company shall have furnished to such counsel such documents as they may
     reasonably request for the purpose of enabling them to pass upon such
     matters.

          (j) The Company shall have executed and delivered a Warrant Agreement
     in a form satisfactory to the Representatives (the "Warrant Agreement"),
     and there shall have been tendered to the Representatives all of the
     Representatives' Warrants described in Section 5(n) hereof to be purchased
     by the Representatives on the Closing Date.

                                      -23-
<PAGE>
 
     All opinions, certificates, letters and documents delivered pursuant to
this Agreement will comply with the provisions hereof only if they are
reasonably satisfactory in all material respects to the Representatives and
counsel for the Representatives.  The Company shall furnish to the
Representatives such conformed copies of such opinions, certificates, letters
and documents in such quantities as the Representatives and counsel for the
Representatives shall reasonably request.

     The respective obligations of the several Underwriters to purchase and pay
for any Option Securities shall be subject, in their discretion, to each of the
foregoing conditions to purchase the Firm Securities, except that all references
to the Firm Securities and the Firm Closing Date shall be deemed to refer to
such Option Securities and the related Option Closing Date, respectively.

     8.   INDEMNIFICATION AND CONTRIBUTION.
          -------------------------------- 

          (a) The Company agrees to indemnify and hold harmless each Underwriter
     and each person, if any, who controls any Underwriter within the meaning of
     Section 15 of the Act or Section 20 of the Exchange Act, against any
     losses, claims, damages or liabilities to which such Underwriter or such
     controlling person may become subject under the Act or otherwise, insofar
     as such losses, claims, damages or liabilities (or actions in respect
     thereof) arise out of or are based upon:

               (i) any breach by the Company of its representations or
          warranties set forth in Section 2(a) and (b) of this Agreement;

               (ii) any untrue statement or alleged untrue statement of any
          material fact contained in (A) the Registration Statement or any
          amendment thereto, the Prospectus or any amendment or supplement
          thereto or (B) any application or other document, or any amendment or
          supplement thereto, executed by the Company or based upon written
          information furnished by or on behalf of the Company filed in any
          jurisdiction in order to qualify the Securities under the securities
          or blue sky laws thereof or filed with the Commission or any
          securities association or securities exchange (each, an
          "Application");

               (iii)  the omission or alleged omission to state in the
          Registration Statement or any amendment thereto, or the Prospectus or
          any amendment or supplement thereto, or any Application, a material
          fact required to be stated therein or necessary to make the statements
          therein not misleading; or

               (iv) any untrue statement or alleged untrue statement of any
          material fact made by the Company or prepared at its direction and
          contained in any audio, visual, electronic or electronically
          transmitted materials produced by the Company or at its direction and
          used in connection with the marketing of the Securities, including
          without limitation, slides, videos, films, Internet presentations,
          tape recordings, and, such party or parties, as the case may be, will
          reimburse, as incurred, each Underwriter and each such controlling
          person for any legal or other expenses reasonably incurred by such
          Underwriter or such controlling person in connection with
          investigating, defending against or appearing as a third-party witness
          in connection with any such loss, claim, damage, liability or action;

                                      -24-
<PAGE>
 
provided, however, that the Company will not be liable in any such case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon any untrue statement or alleged untrue statement or omission or alleged
omission made in such Registration Statement or any amendment thereto, any
Preliminary Prospectus, the Prospectus or any amendment or supplement thereto or
any Application in reliance upon and in conformity with written information
furnished to the Company by any Underwriter through the Representatives
specifically for use therein; and provided, further, that the Company will not
be liable to any Underwriter or any person controlling such Underwriter with
respect to any such untrue statement or omission made in any Preliminary
Prospectus that is corrected in the Prospectus (or any amendment or supplement
thereto) if the person asserting any such loss, claim, damage or liability
purchased Securities from such Underwriter but was not sent or given a copy of
the Prospectus (as amended or supplemented) at or prior to the written
confirmation of the sale of such Securities to such person in any case where
such delivery of the Prospectus (as amended or supplemented) is required by the
Act, unless such failure to deliver the Prospectus (as amended or supplemented)
was a result of noncompliance by the Company with Section 5(d) and (e) of this
Agreement.  The Company shall not, without the prior written consent of the
Representatives, settle or compromise or consent to the entry of any judgment in
any pending or threatened claim, action, suit or proceeding in respect of which
indemnification may be sought hereunder (whether or not any Underwriter or any
person who controls any Underwriter within the meaning of Section 15 of the Act
or Section 20 of the Exchange Act is a party to such claim, action, suit or
proceeding), unless such settlement, compromise or consent includes an
unconditional release of all of the Underwriters and such controlling persons
from all liability arising out of such claim, action, suit or proceeding.

     In addition to its other obligations under this Section 8(a), the Company
agrees that, as an interim measure during the pendency of any claim, action,
investigation, inquiry, or other proceeding arising out of or based upon any
statement or omission, or any alleged statement or omission, described in this
Section 8(a), it will reimburse the Representatives and each Underwriter on a
monthly basis for all reasonable legal fees or other expenses incurred in
connection with investigating or defending any such claim, action,
investigation, inquiry, or other proceeding, notwithstanding the absence of a
judicial determination as to the propriety and enforceability of the Company's
obligation to reimburse the Representatives or Underwriters for such expenses
and the possibility that such payments might later be held to have been improper
by a court of competent jurisdiction.  To the extent that any such interim
reimbursement payment is so held to have been improper, the Representatives and
the Underwriters shall promptly return it to the party or parties that made such
payment, together with interest, compounded daily, determined on the basis of
the prime rate (or other commercial lending rate for borrowers of the highest
credit standing) announced from time to time by Bank of America (the "Prime
Rate").  Any such interim reimbursement payments which are not made to the
Representatives and Underwriters within 45 days of a request for reimbursement
shall bear interest at the Prime Rate from the date of such request.  This
indemnity agreement shall be in addition to any liabilities which the Company
may otherwise have.

          (b) Each Underwriter, severally and not jointly, will indemnify and
     hold harmless the Company, each of its directors, each of its officers who
     signed the Registration Statement, each person, if any, who controls the
     Company within the meaning of Section 15 of the Act or Section 20 of the
     Exchange Act, against any losses, claims, damages or liabilities to which
     the Company or any such director, officer or controlling person of the
     Company may become subject under the Act or otherwise, insofar as such
     losses, claims, damages or liabilities (or actions in respect thereof)
     arise out of or are based upon (i) any untrue statement or alleged

                                      -25-
<PAGE>
 
     untrue statement of any material fact contained in the Registration
     Statement or any amendment thereto, any Preliminary Prospectus or the
     Prospectus or any amendment or supplement thereto, or any Application; (ii)
     the omission or the alleged omission to state therein a material fact
     required to be stated in the Registration Statement or any amendment
     thereto, any Preliminary Prospectus or the Prospectus or any amendment or
     supplement thereto, or any Application or necessary to make the statements
     therein not misleading, in each case to the extent, but only to the extent,
     that such untrue statement or alleged untrue statement or omission or
     alleged omission was made in reliance upon and in conformity with written
     information furnished to the Company by such Underwriter through the
     Representatives specifically for use therein; or (iii) any use of the
     access code for the "NetRoadshow" by other than qualified investors,
     registered broker-dealers or investment advisors which results in action
     taken against the Company by such third party obtaining access to the
     "NetRoadshow"; provided, however, the Underwriter responsible for
     distributing such access code to other than a qualified investor shall be
     the sole party responsible to the Company in connection therewith.  The
     Representatives shall not, without the prior written consent of the
     Company, settle or compromise or consent to the entry of any judgment in
     any pending or threatened claim, action, suit or proceeding in respect of
     which indemnification may be sought hereunder (whether or not the Company
     or any person who controls the Company within the meaning of Section 15 of
     the Act or Section 20 of the Exchange Act is a party to such claim, action,
     suit or proceeding), unless such settlement, compromise or consent includes
     an unconditional release of the Company and such controlling persons from
     all liability arising out of such claim, action, suit or proceeding.  This
     indemnity agreement will be in addition to any liability which such
     Underwriter may otherwise have.

          (c) Promptly after receipt by an indemnified party under this Section
     8 of notice of the commencement of any action, such indemnified party will,
     if a claim in respect thereof is to be made against the indemnifying party
     under this Section 8, notify the indemnifying party of the commencement
     thereof, but the omission so to notify the indemnifying party will not
     relieve it from any liability which it may have to any indemnified party,
     except to the extent that the indemnifying party demonstrates it has been
     irreparably prejudiced by such failure to receive notice.

          (d) In case any such action is brought against any indemnified party,
     and it notifies the indemnifying party of the commencement thereof, the
     indemnifying party will be entitled to participate therein and, to the
     extent that it may wish, jointly with any other indemnifying party
     similarly notified, to assume the defense thereof, with counsel
     satisfactory to such indemnified party; provided, however, that if the
     defendants in any such action include both the indemnified party and the
     indemnifying party and the indemnified party shall have reasonably
     concluded or shall have been advised by its counsel that there may be one
     or more legal defenses available to it and/or other indemnified parties
     that conflict with those available to the indemnifying party, the
     indemnifying party shall not have the right to direct the defense of such
     action on behalf of such indemnified party or parties and such indemnified
     party or parties shall have the right to select separate counsel to defend
     such action on behalf of such indemnified party or parties.  After notice
     from the indemnifying party to such indemnified party of its election so to
     assume the defense thereof and approval by such indemnified party of
     counsel appointed to defend such action, the indemnifying party will not be
     liable to such indemnified party under this Section 8 for any legal or
     other

                                      -26-
<PAGE>
 
     expenses, other than reasonable costs of investigation, subsequently
     incurred by such indemnified party in connection with the defense thereof,
     unless (i) the indemnified party shall have employed separate counsel in
     accordance with the proviso to the next preceding sentence (it being
     understood, however, that in connection with such action the indemnifying
     party shall not be liable for the expenses of more than one separate
     counsel (in addition to local counsel) in any one action or separate but
     substantially similar actions in the same jurisdiction arising out of the
     same general allegations or circumstances, designated by the
     Representatives in the case of paragraph (a) of this Section 8,
     representing the indemnified parties under such paragraph (a) who are
     parties to such action or actions) or (ii) the indemnifying party does not
     promptly retain counsel satisfactory to the indemnified party or (iii) the
     indemnifying party has authorized the employment of counsel for the
     indemnified party at the expense of the indemnifying party.

          (e) In circumstances in which the indemnity agreement provided for in
     the preceding paragraphs of this Section 8 is unavailable or insufficient,
     for any reason, to hold harmless an indemnified party in respect of any
     losses, claims, damages or liabilities (or actions in respect thereof),
     each indemnifying party, in order to provide for just and equitable
     contribution, shall contribute to the amount paid or payable by such
     indemnified party as a result of such losses, claims, damages or
     liabilities (or actions in respect thereof) in such proportion as is
     appropriate to reflect (i) the relative benefits received by the
     indemnifying party or parties on the one hand and the indemnified party on
     the other from the offering of the Securities or (ii) if the allocation
     provided by the foregoing clause (i) is not permitted by applicable law,
     not only such relative benefits but also the relative fault of the
     indemnifying party or parties on the one hand and the indemnified party on
     the other in connection with the statements or omissions or alleged
     statements or omissions that resulted in such losses, claims, damages or
     liabilities (or actions in respect thereof), as well as any other relevant
     equitable considerations.  The relative benefits received by the Company on
     the one hand and the Underwriters on the other shall be deemed to be in the
     same proportion as the total proceeds from the offering (before deducting
     expenses) received by the Company bear to the total underwriting discounts
     and commissions received by the Underwriters.  The relative fault of the
     parties shall be determined by reference to, among other things, whether
     the untrue or alleged untrue statement of a material fact or the omission
     or alleged omission to state a material fact relates to information
     supplied by the Company or the Underwriters, the parties' relative intent,
     knowledge, access to information and opportunity to correct or prevent such
     statement or omission, and any other equitable considerations appropriate
     in the circumstances.  The Company and the Underwriters agree that it would
     not be equitable if the amount of such contribution were determined by pro
     rata or per capita allocation (even if the Underwriters were treated as one
     entity for such purpose) or by any other method of allocation that does not
     take into account the equitable considerations referred to above in this
     paragraph (e).  Notwithstanding any other provision of this paragraph (e),
     no Underwriter shall be obligated to make contributions hereunder that in
     the aggregate exceed the total public offering price of the Securities
     purchased by such Underwriter under this Agreement, less the aggregate
     amount of any damages that such Underwriter has otherwise been required to
     pay in respect of the same or any substantially similar claim, and no
     person guilty of fraudulent misrepresentation (within the meaning of
     Section 11(f) of the Act) shall be entitled to contribution from any person
     who was not guilty of such fraudulent misrepresentation.  The Underwriters'
     obligations to contribute hereunder are several in proportion to their
     respective underwriting obligations and not joint, and as between
     themselves, contributions

                                      -27-
<PAGE>
 
     among Underwriters shall be governed by the provisions of the
     Representatives' Agreement Among Underwriters.  For the purposes of this
     paragraph 8(e), each person, if any, who controls an Underwriter within the
     meaning of Section 15 of the Act or Section 20 of the Exchange Act shall
     have the same rights to contribution as such Underwriter, and each director
     of the Company, each officer of the Company who signed the Registration
     Statement, and each person, if any, who controls the Company within the
     meaning of Section 15 of the Act or Section 20 of the Exchange Act, shall
     have the same rights to contribution as the Company.

     9.   DEFAULT OF UNDERWRITERS.  If one or more Underwriters default in their
          -----------------------                                               
obligations to purchase Firm Securities or Option Securities hereunder and the
aggregate number of such Securities that such defaulting Underwriter or
Underwriters agreed but failed to purchase is ten percent or less of the
aggregate number of Firm Securities or Option Securities to be purchased by all
of the Underwriters at such time hereunder, then the other Underwriters may make
arrangements satisfactory to the Representatives for the purchase of such
Securities by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives), but if no such arrangements are
made by the Firm Closing Date or the related Option Closing Date, as the case
may be, the other Underwriters shall be obligated severally in proportion to
their respective commitments hereunder to purchase the Firm Securities or Option
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase.  If one or more Underwriters so default with respect to an aggregate
number of Securities that is more than ten percent of the aggregate number of
Firm Securities or Option Securities, as the case may be, to be purchased by all
of the Underwriters at such time hereunder, and if arrangements satisfactory to
the Representatives are not made within 36 hours after such default for the
purchase by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives) of the Securities with respect to
which such default occurs, this Agreement will terminate without liability on
the part of any non-defaulting Underwriter or the Company other than as provided
in Section 10 hereof.  In the event of any default by one or more Underwriters
as described in this Section 9, the Representatives shall have the right to
postpone the Firm Closing Date or the Option Closing Date, as the case may be,
established as provided in Section 3 hereof for not more than seven business
days in order that any necessary changes may be made in the arrangements or
documents for the purchase and delivery of the Firm Securities or Option
Securities, as the case may be.  As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 9.  Nothing herein shall relieve any defaulting Underwriter from
liability for its default.

     10.  SURVIVAL.  The respective representations, warranties, agreements,
          --------                                                          
covenants, indemnities and other statements of the Company, its officers, and
the several Underwriters set forth in this Agreement or made by or on behalf of
them, respectively, pursuant to this Agreement shall remain in full force and
effect, regardless of (i) any investigation made by or on behalf of the Company,
any of its officers or directors, any Underwriter or any controlling person
referred to in Section 8 hereof and (ii) delivery of and payment for the
Securities.  The respective agreements, covenants, indemnities and other
statements set forth in Sections 6 and 8 hereof shall remain in full force and
effect, regardless of any termination or cancellation of this Agreement.

     11.  TERMINATION.
          ----------- 

          (a) This Agreement may be terminated with respect to the Firm
     Securities or any Option Securities in the sole discretion of the
     Representatives by notice to the Company

                                      -28-
<PAGE>
 
     given prior to the Firm Closing Date or the related Option Closing Date,
     respectively, in the event that the Company shall have failed, refused or
     been unable to perform all obligations and satisfy all conditions on its
     part to be performed or satisfied hereunder at or prior thereto or, if at
     or prior to the Firm Closing Date or, such Option Closing Date,
     respectively,

               (i) after the respective dates as of which information is given
          in the Registration Statement and the Prospectus, any material adverse
          change or development involving a prospective adverse change in or
          affecting particularly the business, properties, condition (financial
          or otherwise), results of operations or prospects of the Company,
          whether or not arising in the ordinary course of business, occurs
          which would, in the Representatives' sole judgment, make the offering
          or the delivery of the Securities impracticable or inadvisable;

               (ii) trading in the Common Stock shall have been suspended by the
          Commission or the Nasdaq SmallCap Market or minimum or maximum prices
          shall have been established on the Nasdaq SmallCap Market;

               (iii)  a banking moratorium shall have been declared by New York
          or United States authorities; or

               (iv) there shall have been (A) an outbreak or escalation of
          hostilities between the United States and any foreign power, (B) an
          outbreak or escalation of any other insurrection or armed conflict
          involving the United States or (C) any other calamity or crisis or
          material adverse change in general economic, political or financial
          conditions having an effect on the U.S. financial markets that, in the
          sole judgment of the Representatives, makes it impractical or
          inadvisable to proceed with the public offering or the delivery of the
          Securities as contemplated by the Registration Statement, as amended
          as of the date hereof.

          (b) Termination of this Agreement pursuant to this Section 11 shall be
     without liability of any party to any other party except as provided in
     Section 10 hereof.

     12.  INFORMATION SUPPLIED BY UNDERWRITERS.  The statements set forth in (a)
          ------------------------------------

Prospectus, (b) under the heading "Underwriting" in any Preliminary Prospectus

Prospectus pertaining to stabilization (to the extent such statements relate to
the Underwriters) constitute the only information furnished by any Underwriter
through the Representatives to the Company for the purposes of Section 8 hereof.
The Underwriters confirm that such statements (to such extent) are correct.

     13.  NOTICES.  All communications hereunder shall be in writing and, if
          -------

          ----------                                                            
binding upon the several Underwriters, the Company and their respective
successors and legal representatives, and nothing expressed or mentioned in this
Agreement is intended or shall be construed to give any other person any legal
or equitable right, remedy or claim under or in respect of this Agreement, or
any provisions herein contained, this Agreement and all conditions and
provisions hereof being intended to be and being for the sole and exclusive
benefit of such persons and for the benefit of no other person except that (a)
the indemnities of the Company contained in Section 8 of this Agreement shall
also be for the benefit of any person or persons who control any Underwriter
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act
and (b) the indemnities of the Underwriters contained in Section 8 of this
Agreement shall also be for the benefit of the directors of the Company and the
officers of the Company who have signed the Registration Statement and any
person or persons who control the Company within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act.  No purchaser of Securities from any
Underwriter shall be deemed a successor because of such purchase.

     15.  APPLICABLE LAW.  The validity and interpretation of this Agreement,
          --------------                                                     
and the terms and conditions set forth herein, shall be governed by and
construed in accordance with the laws of the State of California, without giving
effect to any provisions relating to conflicts of laws.

     16.  CONSENT TO JURISDICTION AND SERVICE OF PROCESS.  All judicial
          ----------------------------------------------               
proceedings arising out of or relating to this Agreement may be brought in any
state or federal court of competent jurisdiction in the State of California, and
by execution and delivery of this Agreement, the Company accepts for itself and
in connection with their respective properties, generally and unconditionally,
the nonexclusive jurisdiction of the aforesaid courts and waives any defense of
forum non conveniens and irrevocably agrees to be bound by any judgment rendered
thereby in connection with this Agreement.  The Company designates and appoints
Robert A. Spade and such other persons as may hereafter be selected by the
Company irrevocably agreeing in writing to so serve, as its agent to receive on
its behalf service of all process in any such proceedings in any such court,
such service being hereby acknowledged by the Company to be effective and
binding service in every respect.  A copy of any such process so served shall be
mailed by registered mail to the Company at its address provided in Section 13
hereof; provided, however, that, unless otherwise provided by applicable law,
any failure to mail such copy shall not affect the validity of service of such
process.  If any agent appointed by the Company refuses to accept service, the
Company hereby agrees that service of process sufficient for personal
jurisdiction in any action against the Company in the State of California may be
made by registered or certified mail, return receipt requested, to the Company
at its address provided in Section 13 hereof, and the Company hereby
acknowledges that such service shall be effective and binding in every respect.
Nothing herein shall affect the right to serve process in any other manner
permitted by law or shall limit the right of any Underwriter to bring
proceedings against the Company in the courts of any other jurisdiction.

     17.  NO RULE OF CONSTRUCTION.  The parties acknowledge that this Agreement
          -----------------------                                              
was initially prepared by the Representatives, and that all parties have read
and negotiated the language used in this Agreement.  The parties agree that,
because all parties participated in negotiating and drafting this Agreement, no
rule of construction shall apply to this Agreement which construes ambiguous
language in favor of or against any party by reason of that party's role in
drafting this Agreement.

     2.1       Transfer of Stock.  On the Closing Date and subject to the terms
               -----------------                                               
               and conditions set forth in this Agreement, the Stockholders will
               sell, convey, assign, transfer and
<PAGE>
 
               deliver all of the issued and outstanding Stock to Purchaser,
               free and clear of all Liens with respect thereto.

     2.2       Purchase Price.
               -------------- 

      (a) The total consideration (the "Purchase Price") to be paid and/or
provided by Purchaser to Stockholders for the Stock shall be as set forth below
which amounts shall be divided equally among the three Stockholders (i.e., one-
third (1/3/rd/) each), to be paid as follows:

           (A) The Standstill Payments previously paid by Purchaser (i.e.,
      $225,000 or such greater amount as actually paid);

           (B) (i) Purchaser shall, on the first anniversary of the Closing
      Date, deliver to the Stockholders (or their estates, in the case of
      deceased Stockholders who are natural Persons) Certificates for duly
      authorized, validly issued, fully paid and nonassessable shares of common
      stock of Purchaser ("Purchaser Common Stock") equal in number to
      $2,070,000 divided by the "Price to Public" of Purchaser Common Stock set
      forth on the cover of the final prospectus relating to the Proposed Public
      Offering; provided, however that the number of shares of Purchaser Common
                -----------------         
      Stock to be issued and delivered may be reduced by set-off pursuant to
      Article XI hereof. Purchaser Common Stock shall be issued (and registered
      in the name of) one-third to each of the Stockholders.

               (ii)  If any time after the completion of the Closing but prior
      to the issuance and delivery of Purchaser Common Stock pursuant to this
      subsection, Purchaser increases or decreases the number of its issued and
      outstanding shares of Common Stock of Purchaser, or changes in any way the
      rights and privileges of such shares of Common Stock, by means of (a) the
      payment of a share dividend or the making of any other distribution on
      such shares of Common Stock payable in its shares of Common Stock, (b) a
      split or subdivision of shares of Common Stock, or (c) a merger,
      consolidation or combination of shares of Common Stock, then the number of
      shares of Purchaser Common Stock to be issued pursuant to this subsection
      shall be proportionately adjusted so that the number of shares of
      Purchaser Common Stock shall be increased, decreased or changed in like
      manner, as if Purchaser Common Stock required to be issued pursuant to
      this Subsection immediately prior to the event had been issued,
      outstanding, fully paid and nonassessable at the time of such event. Any
      dividend paid or distributed on the shares of Common Stock in shares of
      any other class of Purchaser or securities convertible into shares of
      Common Stock shall be treated as a dividend paid in shares of Common Stock
      to the extent shares of Common Stock are issuable on the payment or
      conversion thereof. Any adjustment made pursuant to this Subsection shall,
      in the case of a stock dividend or distribution, become effective as of
      the record date therefor and, in the case of a split, subdivision,
      consolidation or combination, be made as of the effective date thereof.
      Purchaser shall not be required to deliver fractions of shares of Common
      Stock; provided, however, that Purchaser shall purchase such fraction for
      an amount in cash equal to the current value of such 
<PAGE>
 
      fraction computed on the basis of the closing bid price on the trading day
      immediately preceding the day upon such Purchaser Common Stock is required
      to be delivered.

               (iii)  The obligation of Purchaser to deliver Purchaser Common
      Stock shall not entitle the Stockholders to any of the rights of
      shareholders or to any dividend declared on the shares of Purchaser Common
      Stock unless the record date fixed by the Board of Directors of Purchaser
      for the determination of holders of shares of Common Stock entitled to
      such dividend or other right is set after the first anniversary of the
      Closing Date and the Stockholders are still holders of the Purchaser
      Common Stock as of such record date.

          (C) Purchaser shall pay a total of $3,300,000 (less the Standstill
      Payments previously paid and the Escrow Payments) in cash, payable by wire
      transfer or other immediately available funds on the Closing Date, payable
      one-third to each of the Stockholders (the "Cash Payments"); and

          (D) Purchaser shall pay to the Escrow Agent, in its capacity as the
      Escrow Agent under the terms of the Escrow Agreement with each of the
      Stockholders, a total of an amount equal to $385,430.00 in cash payable by
      wire transfer or other immediately available funds on the Closing, to be
      held and disbursed in accordance with the terms of the Escrow Agreement
      (the "Escrow Payments").

          (b) Purchaser agrees that: (a) it shall claim a tax basis in the Stock
equal only to the sum of the Standstill Payments plus the Cash Payments plus the
Escrow Payments until the Purchaser Common Stock is delivered pursuant to
Section 2.2(a)(B) hereof; (b) when the Purchaser Common Stock is delivered, it
shall increase its tax basis in the Stock by the fair market value of the
Purchaser Common Stock on such delivery date and (c) if delivery of the
Purchaser Common Stock is deferred longer than one year after the Closing Date,
Purchaser shall be required to report a portion of the Purchaser Common Stock as
an interest payment in accordance with the Code and regulations promulgated
thereunder.  The Stockholders agree that they shall not report the transactions
contemplated by this Agreement in a manner inconsistent therewith.

     2.3  Registration Rights.
          ------------------- 

          (a)  At any time after the first anniversary of the Closing Date, any,

               Stockholder), in order to comply with the provisions of the
               Securities Act of 1933, as amended (the "Act"), as to permit a
               public offering and sale of the Purchaser Common Stock by the
               Stockholders; provided however, that Purchaser shall not be
                             ----------------
               obligated to

               effect any such registration if Purchaser shall furnish to the
               Stockholders a certificate signed by the President of Purchaser
               stating that in the good faith judgment of the Board of Directors
               of Purchaser, it is currently entering into, or engaged in
               discussions with respect to, a transaction for which a Form 8-K,
               including financial statements, will need to be filed with the
               Commission, in which event Purchaser shall have the right to
               defer the filing of the Registration Statement for a period of
               not more than 90 days after receipt of the request of any of the
               Stockholders pursuant to this Section 2.3.

          (b)  For the purposes of this Section 2.3, Purchaser shall not be
               deemed to have satisfied its obligations hereunder, unless

                     Statement to become effective under the Act within ninety

                     comply with the provisions of the Act with respect to the
                     disposition of all securities covered by the Registration
                     Statement;

               (iii) Filed such supplements and post-effective amendments as may
                     be required in order that the Registration Statement shall

                     the Stockholders to dispose of all of the Purchaser Common
                     Stock without regard as to whether any shares of the
                     Purchaser Common Stock shall otherwise become freely
                     tradable without restriction under the Act by any or all of
                     the Stockholders pursuant to Rule 144 promulgated under the

                     be reasonably appropriate for the distribution of the
                     securities covered by said Registration Statement, except
                     no such registration shall be required in any jurisdiction
                     where solely as a result of such registration Purchaser
                     would be subject to service of general process or to
                     taxation or qualification as a foreign corporation doing
                     business in such jurisdiction.

Statement to become effective within 90 days of filing such Registration
Statement, then Purchaser shall pay to the Stockholders a penalty of $2,500 per
day for each day said effectiveness is delayed beyond the expiration of such 90
day period.  Said penalties shall be payable on a monthly basis, in arrears,
commencing on the first day of the month following the expiration of such 30 or
90 day period, as the case may be, and on the first day of each month

          Stockholders to sell the Purchaser Common Stock to the public without
          registration, Purchaser shall (a) make and keep "public information"
          available, as such terms are contemplated and defined in Rule 144, (b)

     The Company and each of the Stockholders jointly and severally (except with

represent and warrant to Purchaser as follows.

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

          the jurisdictions in which the ownership, lease or operation of its
          property or the conduct of its business requires such qualification,
          except jurisdictions in which the failure to be so qualified or
          licensed would not reasonably be expected to have a Material Adverse
          Effect. The Stockholders have delivered to Purchaser complete and

                        become subject under the Act or otherwise (which will,

                        fact contained in any registration statement, amendment,

                        Rights set forth in Section 2.3 hereof, unless such
                        untrue statement or alleged untrue statements were made

                        Company or a Stockholder, or (B) any violations by the
                        Purchaser of the Act or state securities laws. The
                        Purchaser shall reimburse the Company or any such person
                        for any legal or other expenses reasonably incurred in
                        connection with investigating or defending against any
                        such claim, damage, liability or action, proceeding or
                        investigation to which such indemnity obligation
                        applies, and such indemnity obligations shall be in
                        addition to any liability of the Purchaser herein or
                        otherwise at law or equity. The obligations of the
                        Purchaser under this Section 11.2(b) shall survive the
                        termination of this Agreement for any reason prior to
                        Closing.

        11.3    Procedures for Third-Party Claims.
                --------------------------------- 

                (a)     If any Indemnitee receives written notice of the
                        assertion of any claim or of the commencement of any
                        action or proceeding by any Governmental Authority or
                        any person or entity who is not a party to this
                        Agreement (a "Third Party Claim") against or affecting
                        such Indemnitee, and if such assertion were presumed to
                        be true (regardless of the actual outcome) then a party
                        could be obligated to provide indemnification under this
                        Agreement as a result of or in connection with such
                        claim, action or proceeding, such Indemnitee will give
                        such Indemnifying Party reasonably prompt written notice
                        thereof, but in any event no later than thirty (30)
                        calendar days after receipt of such written notice of
                        such Third Party Claim; provided however, that failure
                        to give notice as provided in this paragraph (a) shall
                        not relieve the Indemnifying Party of its
                        indemnification obligations under this Article XI except
                        to the extent that such Indemnifying Party is actually
                        prejudiced by such failure. Said written notice to the
                        Indemnifying Party shall set forth the basis of the
                        Third Party Claim in reasonable detail and include
                        copies of all pertinent correspondence relating to such
                        Third Party
<PAGE>
 
          Claim. The Indemnifying Party (which, in the case of any matter for
          which the Stockholders are severally liable and for purposes of this
          Section 11.3 shall act as a single group) will have the right to
          assume and control the defense of any Third Party Claim at such
          Indemnifying Party's sole expense and by such Indemnifying Party's own
          counsel (which counsel must be reasonably satisfactory to the
          Indemnitee), by giving written notice to the Indemnitee (the "Notice
          to Defend") no later than thirty (30) calendar days after receipt of
          the above-described notice of such Third Party Claim. The Indemnitee
          also will have the right to participate in the defense of any Third
          Party Claim assisted by counsel of its own choosing, but all fees and
          expenses of such counsel shall be paid by the Indemnitee. The
          Indemnifying Party and the Indemnitee will reasonably cooperate with
          each other in good faith in such defense and make available all
          employees and books and records in its control as reasonably deemed
          necessary with respect to such defense (but not to the extent that
          would require waiver of any privilege). If the Indemnitee does not
          receive from the Indemnifying Party a Notice to Defend with respect to
          a Third Party Claim or a written notice of objection to the claim for
          indemnification specifying in reasonable detail the basis for the
          objection within the thirty (30) day period described above, the
          Indemnitee may, at its option, elect to solely defend the Third Party
          Claim assisted by counsel of its own choosing, and the Indemnifying
          Party will be liable for all reasonable costs and expenses, and all
          settlement amounts (subject to and in accordance with paragraph (c)
          below of this Section 11.3) or other liabilities, losses, damages and
          injuries paid or incurred in connection therewith to the extent such
          claim is or would have been indemnifiable under this Agreement if such
          claim is or had been proved.

     (b)  If, within the thirty (30) day period set forth in paragraph (a) above
          of this Section 11.3, an Indemnitee receives a Notice to Defend from
          an Indemnifying Party with respect to any Third Party Claim, the
          Indemnifying Party will not be liable for any legal expenses of the
          Indemnitee incurred after receipt by the Indemnitee of such Notice to
          Defend.

     (b)  In the event there is a dispute between the Indemnifying Party and
          Indemnitee concerning whether a Third Party Claim should be contested,
          settled or compromised, it shall be settled, compromised or contested,
          in accordance with the next succeeding sentences; provided, however,
                                                            --------  -------
          that the Indemnitee, or its respective successors or assigns, shall
          neither be required to refrain from paying or satisfying any claim
          which has matured by court judgment or decree, unless appeal is taken
          thereafter and proper appeal bond posted by the Indemnifying Party,
          nor shall the Indemnitee be required to refrain from paying or
          satisfying any Third Party Claim after and to the extent that such
          Third Party Claim has resulted in an unstayed injunction. The
          Indemnifying Party shall not, without the Indemnitee's prior written
          consent, not to be unreasonably withheld, settle or compromise any
          action or claim or consent to the entry of any judgment with respect
          to any action, claim or proceeding.

<PAGE>
 
          Subject to the foregoing, in the event that the Indemnifying Party, on
          the one hand, or the Indemnitee, on the other hand, has reached a good
          faith, bona fide settlement, agreement or compromise, subject only to
          approval hereunder, with any claimant regarding a matter which may be
          the subject of indemnification hereunder and desires to settle on the
          basis of such agreement or compromise, such party who desires to so
          settle or compromise shall notify the other party in writing of its
          desire setting forth the terms of such settlement or compromise (the
          "Notice of Settlement"). The Third Party Claim may be settled or
          compromised on such basis unless within twenty (20) days of the
          receipt of the Notice of Settlement the party who issued the Notice of
          Settlement receives a notice from the other party of its desire to
          continue to contest the matter (the "Notice to Contest") and, in such
          case:

          (i)   Should the Indemnitee deliver a Notice to Contest, the claim
                shall be so contested and the liability of the Indemnifying
                Party shall be limited as provided in clause (iii) below;

          (ii)  If the settlement or compromise could result in a further claim
                for indemnification being made against the Indemnifying Party
                and if the Indemnifying Party delivers the Notice to Contest,
                the claim shall be so contested and the liability of the
                Indemnitee shall be limited as provided in clause (iii) below;
                and

          (iii) If a matter is contested as provided in clauses (i) or (ii)
                above and is later adjudicated, settled, compromised or
                otherwise disposed of and such adjudication, compromise,
                settlement or disposition results in a liability, loss, damage
                or injury in excess of the amount for which one party desired
                previously to settle the matter, then the liability of such
                party shall be limited to such lesser proposed settlement amount
                (plus attorney's fees and expenses to the date of the proposed
                but unapproved settlement to the extent provided for in
                paragraphs (a) and (b) above) and the party contesting the
                matter shall be solely responsible for any additional amount.

     11.4 Direct Claim.  Any claim for which an Indemnitee intends to assert a
          ------------                                               
          right to indemnifiable Damages under this Agreement which does not
          result from a Third-Party Claim (a "Direct Claim") shall be asserted
          by giving each Indemnifying Party reasonably prompt written notice
          thereof, and each Indemnifying Party shall have a period of thirty
          (30) calendar days within which to respond to such Direct Claim. If
          any Indemnifying Party does not so respond within such thirty (30)
          calendar day period, such Indemnifying Party shall be deemed to have
          rejected such claim, in which event the Indemnitee shall be free to
          pursue such remedies as may be available to the Indemnitee pursuant to
          this Agreement. A failure to give timely notice as provided in this
          Section 11.4 shall not affect the rights or obligations of any party
          hereunder except and only to the extent that, as a result of such
          failure, any party which was entitled to receive such notice was
          deprived of its right to recover any

<PAGE>
 
          payment under its applicable insurance coverage, incurred an
          obligation or liability which otherwise would have been avoided, or
          was otherwise actually prejudiced.

     11.5 Limitations of Indemnification Obligations.
          ------------------------------------------ 

          (a)  All warranties, representations, conditions, covenants,
               agreements and undertakings of the parties under this Agreement
               shall survive the consummation of the Closing hereunder;
               provided, however, claims by the Purchaser Indemnitees against
               the Stockholders for the breach of any warranty or representation
               contained in Article III hereof and claims by Stockholder
               Indemnitees against Purchaser for the breach of any warranty or
               representation contained in Article IV hereof shall survive only
               for 12 months following the Closing Date. All other obligations
               shall be unlimited as to duration. Any claims for indemnification
               based upon any such breach which are pending on or asserted or
               identified prior to the expiration of the 12 month time period
               specified above may continue to be made and indemnified against
               pursuant to this Agreement and the Escrow Agreement and the
               related obligation to indemnify shall not terminate.

          (b)  Losses Net of Insurance, Etc.  The amount of any Damages suffered
               ----------------------------
               as a result of an injury to an Indemnitee for which
               indemnification is available hereunder, shall be net of any
               insurance proceeds, if any, actually received by the Indemnitee
               in respect of such injury and (i) increased to take account of
               any net tax cost incurred by the Indemnitee arising from the
               receipt of indemnity payments hereunder (grossed up for such
               increase and any tax consequences resulting from any payments
               pursuant to this Section 11.5(b)) and (ii) reduced to take
               account of any net tax benefit realized by the Indemnitee arising
               from the incurrence or payment of any such Damage. In computing
               the amount of any such tax cost or tax benefit, the Indemnitee
               shall be deemed to recognize all other items of income, gain,
               loss, deduction or credit before recognizing any item arising
               from the receipt of any indemnity payment hereunder or the
               incurrence or payment of any indemnified Damages. Any indemnity
               payment under this Agreement shall be treated as an adjustment to
               the Purchase Price for tax purposes, unless a final determination
               (which shall include the execution of a Form 870-AD or successor
               form) with respect to the Indemnitee or any Affiliate of such
               Indemnitee causes any such payment not to be treated as an
               adjustment to the Purchase Price for Federal tax purposes. The
               purpose of this Section 11.5(b) is to put the Indemnitee in such
               a position as if the Damage for which indemnification is provided
               hereunder had not occurred.

          (c)  Exclusive Remedy.  The parties acknowledge and agree that after
               ----------------
               the Closing the indemnities set forth in this Article XI shall be
               the sole and exclusive remedy for breach, default, inaccuracy or
               failure of any of the warranties, representations, conditions,
               covenants or agreements contained in this Agreement and in any
               certificates or documents delivered pursuant hereto,

<PAGE>
 
               except in the case of judicially determined fraud, intentional or
               willful misrepresentation or breach, equitable remedies and
               except that the Stockholders shall have the right to seek
               specific performance and/or to pursue any and all remedies
               available at law or in equity (all of which shall be cumulative)
               in connection with any failure of the Purchaser to perform its
               obligations under Sections 2.2(a)(B), 2.3 and/or 2.4. The
               foregoing is not intended to limit or in any way affect the
               respective rights and obligations of the parties under the Escrow
               Agreement and/or the employment agreements and consulting
               agreement entered into by the Purchaser.

          (d)  No Lost Profits.  Notwithstanding anything to the contrary in
               ---------------
               this Agreement, except for any breach of Purchaser's obligations
               under Sections 2.2(a)(B), 2.3 and 2.4 hereof, in no event will
               any party hereto have any liability under this Agreement to any
               other party hereto for consequential, indirect or incidental
               damages of any kind or nature or lost profits.

          (e)  Maximum Indemnification by Purchaser. With respect only to claims
               ------------------------------------
               by Stockholder Indemnitees against Purchaser for indemnification
               based upon breaches defaults or inaccuracies of the warranties
               and representations contained in Article IV, there shall be an
               aggregate limitation of $2,070,000.00. There shall be no
               limitation on Purchaser's liability for, or in connection with,
               any of its other obligations under this Agreement.

     11.6 Recourse for Indemnification by the Stockholders.
          ------------------------------------------------ 

          (a)  To induce the Purchaser and the Stockholders to enter into this
Agreement and to serve as the sole recourse for the indemnity obligations of the
Stockholders under this Article XI (except as set forth in Sections 11.6(e) and
11.7), the Purchaser shall have a right of set-off against the shares of
Purchaser Common Stock to be issued to the Stockholders (to be exercised prior
to their issuance) to enforce the Stockholders' obligations and the Purchaser
Indemnitees collective rights.  Except for breaches referred to in Section
11.6(e), said right of set-off shall be exercised equally with respect to each
of the Stockholders (i.e., one-third (1/3/rd/) against the Purchaser Common
Stock to be issued to each Stockholder.

          (b)  Notwithstanding anything contained in this Agreement (or in any
instrument or document delivered pursuant hereto; provided, however that the
                                                  -----------------         
parties agree and acknowledge that Purchaser shall have rights against the
Escrow Payment (to the extent and as provided in the Escrow Agreement) and
Purchaser shall have certain indemnification rights under the related Employment
Agreements and the Consulting Agreement) to the contrary, Purchaser hereby
acknowledges and agrees as follows, except as and to the extent provided in (e)
below with respect to any breach of the representations and warranties contained
in Section 3.2 hereof, that:

               (i)   the Stockholders shall have no personal liability of any
                     sort under or in connection with this Agreement and/or any
                     related instrument or document;

<PAGE>
 
               (ii)  after the Closing, the sole and exclusive right, remedy and
                     recourse of the Purchaser, any Purchaser Indemnitee and/or
                     any other person claiming by, through or under the
                     Purchaser for the enforcement of breach, default,
                     inaccuracy or failure of any of the warranties,
                     representations, conditions, covenants or agreements on the
                     part of any of the Company or the Stockholders (and/or for
                     any other obligation of any of the Company or the
                     Stockholders) in, under, pursuant to or in connection with
                     this Agreement and/or any instrument or document made or
                     delivered pursuant thereto, whether for Damages or other
                     legal or equitable relief, and whether based upon contract,
                     tort, fraud, or upon any other theory of law, shall be said
                     right of set-off against the Purchaser Common Stock to be
                     issued pursuant to Section 2.2(a)(B).

               (iii) the Purchaser, for itself and its successors and assigns,
                     and any Purchaser Indemnitees hereby irrevocably waive and
                     relinquish any and all right to pursue any Action relating
                     to this Agreement of any kind or nature against the
                     Stockholders or any of their respective assets other than
                     an Action against the Purchaser Common Stock as aforesaid;

               (iv)  the limitations on the liability of the Stockholders set
                     forth herein were a material inducement to the Stockholders
                     entering into this Agreement, and but for said limitations,
                     the Stockholders would not have entered into this
                     Agreement; and

               (v)   Purchaser shall be responsible for any and all reasonable
                     legal and other costs and expenses paid or incurred by the
                     Stockholders (or any of them) in enforcing the foregoing
                     limitations on liability.

          (c)  Purchaser shall have the right (pending judicial determination or
mutual agreement as to the amount of claimed Damages for which set-off may be
made) to set-off from the number of shares owed to the Stockholders pursuant to
Section 2.2(a)(B) hereto a number of shares equal to (x) any and all Damages
which may be asserted against, imposed upon or sustained by a Purchaser
Indemnitee by reason of or arising out of the breach, default, inaccuracy or
failure of any of the warranties, representations, covenants or agreements of
the Company or the Stockholders contained in this Agreement or in any
certificate or instrument required to be delivered pursuant hereto divided by
(y) the Fair Market Value of the shares of Purchaser Common Stock as of the
first anniversary of the Closing Date

          (d)  For purposes of this Agreement, shares of Purchaser Common Stock
shall be deemed to have a "Fair Market Value" per share equal to the daily
average of the volume-weighted average trading price per share of Purchaser
Common Stock as quoted by Bloomberg (or if Bloomberg service is not available,
the daily average closing bid price per share as reported on the Nasdaq) for
each trading day of the most recent period of twenty consecutive trading days
ending prior to the date of determination.

<PAGE>
 
          (e)  In the event any Stockholder breaches any of such Stockholder's
representations or warranties contained in Section 3.2, such Stockholder (but
not any of the other Stockholders) shall be liable for any and all Damages which
are actually sustained by a Purchaser
Indemnitee by reason of such breach.  With respect to such Damages only,
Purchaser shall have the right to recover against the Purchaser Common Stock and
against such Stockholder personally.

     11.7 WorldCom Dispute.
          ---------------- 

     (a)  Unless on or prior to the first anniversary of the Closing Date the
WorldCom Dispute has been adjudicated, arbitrated or settled in the favor of the
Company or in the favor of WorldCom for an amount less than or equal to
$365,000, then, as an adjustment of the Purchase Price, Purchaser shall have the
right to recover against certain portions of the Escrow Payment and set-off from
the Purchaser Common Stock to be issued to the Stockholders as follows:

               (i)   If on the first anniversary of the Closing Date the
WorldCom Dispute has not been adjudicated, arbitrated or settled then Purchaser
shall be entitled to $770,860.35 ($1,135,860.35 less $365,000) to be recovered
pursuant to Section 11.7(a)(iii) below.

               (ii)  If on or prior to the first anniversary of the Closing Date
the WorldCom Dispute has been adjudicated, arbitrated or settled in favor of
WorldCom for an amount greater than $365,000 then Purchaser shall be entitled to
the amount of such adjudication, arbitration or settlement plus reasonable
attorneys' fees and costs and related consulting fees less $365,000 to be
recovered pursuant to Section 11.7(a)(iii) below as of the date of such
adjudication, arbitration or settlement.

               (iii) Any amount to be recovered pursuant to Section (i) and (ii)
shall be exclusively recovered equally (i.e., one-half) from the Escrow Payments
and from set-offs from the Purchaser Common Stock based on the Fair Market Value
of the Purchaser Common Stock.

     (b)  Said right of recovery against the Escrow Payment and right of set-off
from the Purchaser Common Stock to be issued shall be the sole remedy for
Purchaser, and in no case shall any Stockholder be personally liable with
respect to any such amounts recoverable  in connection with the WorldCom
Dispute.

     (c)  The obligations of the Stockholders and the rights of the Purchaser
under this Section 11.7 are conditioned upon (i) Purchaser vigorously defending
the WorldCom Dispute and vigorously pursuing its counterclaims in connection
therewith, all with counsel reasonably acceptable to the Stockholders (it being
agreed that Parcel, Mauro & Spaanstra, P.C. is acceptable to the Stockholders),
and (ii) John Lynch being authorized to pursue the settlement of the WorldCom
Dispute with WorldCom on terms reasonably acceptable to Purchaser, and (iii)
Purchaser shall not settle the WorldCom Dispute prior to the first anniversary
of the Closing Date without the prior written consent of the Stockholders, which
consent shall not be unreasonably withheld.

     (d)  If WorldCom offers or agrees (or otherwise indicates its willingness)
to settle the WorldCom Dispute for the payment of a sum certain, regardless of
whether the Purchaser or the Company accepts said offer or agreement or
consummates said settlement, then, at the option of the 

<PAGE>
 
Stockholders, the WorldCom Dispute shall be deemed to have been settled for said
sum certain; provided, however that if such offer, agreement or indication of
             -----------------    
settlement contains additional conditions (i.e. other than the payment of money
and delivery of a release) that Purchaser reasonably deems commercially
unreasonable, then the Stockholders shall not have the option to deem the
WorldCom Dispute settled unless such offer, agreement or indication of
settlement is actually accepted by Purchaser or the Company; provided, further
                                                             --------- ------- 
that if the Company or Purchaser attempts on a timely basis to settle with
WorldCom based on such offer, agreement or indication of WorldCom, Inc.'s
willingness to settle the WorldCom Dispute for the payment of a sum certain and
the Company or Purchaser is unable to complete such settlement solely because
WorldCom withdraws or materially changes such offer, agreement or indication,
then the Stockholders shall not have the option to deem the WorldCom Dispute
settled.

     (e)  In the event that after the first anniversary of the Closing Date, but
before the second anniversary of the Closing Date, the WorldCom Dispute is
settled or otherwise satisfied for less than $1,135,860.35, then the Purchaser
shall promptly (but in any event within 30 days) pay and provide to the
Stockholders the sums recovered from the Escrow Payment and the number of shares
of Purchaser Common Stock set-off against in excess of such amounts as Purchaser
would have been entitled to recover and set-off had the WorldCom Dispute been
settled for said amount prior to said first anniversary. In the event the
Stockholders have exercised their demand registration right under Section 2.3
prior to the issuance and delivery of such additional shares of Purchaser Common
Stock pursuant to this Subsection, then the Stockholders shall not be entitled
to a second demand registration right with respect to such shares of Purchaser
Common Stock.

     11.8 Survival of Representations, Warranties and Covenants.  The
          -----------------------------------------------------      
          representations, warranties, covenants, indemnities, conditions and
          agreements contained herein are and will be deemed to be continuing
          representations, warranties, covenants, indemnities, conditions and
          agreements that survive the Closing and remain in full force and
          effect regardless of any investigations or knowledge of or on behalf
          of any party, but subject to the applicable limitations contained in
          this Article XI.

     11.9 Third Parties.  It is the intention and agreement of the parties that
          -------------                                                   
          the obligations of the Stockholders to the Purchaser under this
          Article XI do not and will not create any rights whatsoever in any
          third parties other than the Purchaser Indemnitees and Stockholder
          Indemnitees; provided, however that the Purchaser Indemnitees and
          Stockholder Indemnitees shall not have any rights or remedies under
          this Agreement beyond those granted to the Purchaser and the
          Stockholders, respectively.

                                  ARTICLE XII

                                  TERMINATION

     12.1 Termination of this Agreement.
          ----------------------------- 

          (a)  In the event that for any reason the Closing shall not have
               occurred on or before June 30, 1998 (the "Termination Date"),
               then the Company and the Stockholders or Purchaser shall have the
               right (regardless of whether such person or persons is in
               material breach of its obligations under this Agreement),
               exercisable at any time after such date by notice in writing, to
               terminate this Agreement and its obligations hereunder.

          (b)  In the event that, on or prior to the Termination Date, any Party
               (the "Breaching Party") is in material breach of its or their
               obligations under this Agreement (and such breach cannot
               reasonably be expected to be cured by the Breaching Party prior
               to the Termination Date, or the Breaching Party is not taking
               reasonable efforts to cure such breach, and, in either event,
               such breach is not waived), then, so long as any other Party (the
               "Non-Breaching Party") entitled to the benefit of such
               obligations is not in default of its or their obligations under
               this Agreement, the Non-Breaching Party shall have the right, as
               its sole and exclusive remedy in event of such breach, to
               terminate this Agreement pursuant to this Article XII (unless
               such breach is or has been cured prior to the giving of such
               notice of termination). The failure of the Proposed Public
               Offering to be completed shall not constitute a material breach
               of this Agreement so long as Purchaser uses its best efforts to
               cause such Registration Statement to become effective. The sole
               remedy of the Company and the Stockholders in the event of such a
               failure of the Proposed Public Offering to be completed shall
               that described in Section 12.2(a)(i). Failure by the Purchaser to
               timely pay any Standstill Payment shall constitute material
               breach by the Purchaser.

          (c)  If any party attempts to terminate this Agreement for any reason
               other than those contained in Section 12.1(a) or (b), such
               termination shall constitute a material breach of this Agreement
               by the terminating party.

     12.2 Effect of Termination.
          --------------------- 

          (a)  Termination by Stockholders or the Company.  Notwithstanding
               ------------------------------------------
               anything contained in this Agreement or in the Standstill
               Agreements to the contrary, if this Agreement is terminated by
               any of the Stockholders or the Company: (i) pursuant to Section
               12.1(a) then Purchaser shall forfeit and the Company shall retain
               any Standstill Payments paid by Purchaser as liquidated damages
               to the Company, or (ii) pursuant to Section 12.1(b) then
               Purchaser shall forfeit and the Company shall retain any
               Standstill Payments paid by

<PAGE>
 
               Purchaser and Purchaser shall pay to the Company a fee equal to
               $150,000 as liquidated damages to the Company; and thereupon, in
               each such case, the parties shall be released of all further
               liabilities under this Agreement.

          (b)  Termination by Purchaser.  Notwithstanding anything contained in
               ------------------------
               this Agreement or in the Standstill Agreements to the contrary,
               if this Agreement is terminated by Purchaser: (i) pursuant to
               Section 12.1(a) then Purchaser shall forfeit and the Company
               shall retain any Standstill Payments paid by Purchaser as
               liquidated damages to the Company, or (ii) pursuant to Section
               12.1(b) then the Company shall return all Standstill Payments to
               Purchaser and the Company shall pay to Purchaser a fee equal to
               $150,000 as liquidated damages to Purchaser; and thereupon, in
               each case, the parties shall be released of all further
               liabilities under this Agreement.

     12.3 Sole Remedy for Termination.  The remedies provided in Section 12.2(a)
          ---------------------------                                  
          and (b) shall constitute the sole and exclusive rights and remedies of
          the Purchaser, on one hand, and of the Company and the Stockholders,
          on the other, against the other in the event of any termination of
          this Agreement by any party for any reason and/or breach of this
          Agreement by any party prior to the consummation of the Closing under
          this Agreement. Notwithstanding anything contained in this Agreement
          to the contrary, except for the right of Purchaser to terminate this
          Agreement under Section 12.1(b) above and to receive the return of the
          Standstill Payments and receive payment of $150,000 from the Company
          as provided in Section 12.2 above, Purchaser hereby acknowledges and
          agrees that it shall have no right to seek or pursue damages, specific
          performance and/or any other rights or remedies, whether at law or in
          equity, against the Company and/or against any of the Stockholders for
          or on account of or in connection with any breach of or failure or
          refusal to perform any of their respective obligations under this
          Agreement (regardless of whether such breach or failure or refusal to
          perform is intentional or unintentional). Notwithstanding anything
          contained in this Agreement to the contrary, except for the right of
          the Company or the Stockholders to terminate this Agreement under
          Section 12.1(a) or (b) above and to retain the Standstill Payments
          and/or receive payment of $150,000, as the case may be, from Purchaser
          as provided in Section 12.2 above, the Company and the Stockholders
          hereby acknowledge and agree that it shall have no right to seek or
          pursue damages, specific performance and/or any other rights or
          remedies, whether at law or in equity, against Purchaser for or on
          account of or in connection with any breach of or failure or refusal
          to perform any of its obligations under this Agreement (regardless of
          whether such breach or failure or refusal to perform is intentional or
          unintentional). The parties acknowledge that the foregoing limitations
          on the liability of the parties hereto and on the rights and remedies
          of the other parties are a material inducement to the parties entering
          into this Agreement. Purchaser shall be responsible for any and all
          reasonable legal and other costs and expenses paid or incurred by the
          Company or the Stockholders (or any of them) in enforcing the
          foregoing limitations on their liability. The Company and the
          Stockholders shall be responsible for any and all reasonable legal and
          other costs and expenses paid or incurred by the Purchaser in
          enforcing the foregoing limitations on its liability.

                                 MISCELLANEOUS

     13.1 Entire Agreement.  This Agreement, which also includes the Exhibits
          ----------------                                          
          and Schedules hereto, sets forth the entire agreement and
          understanding among the parties and merges and supersedes all prior
          discussions, agreements and understandings of every kind and nature
          among them as to the subject matter hereof, and no party shall be
          bound by any condition, definition, warranty or representation other
          than as expressly provided for in this Agreement or as may be on a
          date on or subsequent to the date hereof duly set forth in writing
          signed by each party which is to be bound thereby. Except as otherwise
          expressly provided herein, the foregoing is not intended to supersede
          or otherwise affect the respective rights and obligations of the
          parties under the Standstill Agreement dated October 31, 1997, the
          Reciprocal Telecommunications Agreement or the Confidentiality
          Agreement.

     13.2 Amendments.  This Agreement (including the Exhibits and Schedules
          ----------                                                       
          hereto) shall not be changed, modified or amended except by a writing
          signed by each party to be charged, and this Agreement may not be
          discharged except by performance in accordance with its terms or by a
          writing signed by each party to be charged. The rights and remedies of
          the parties hereunder are cumulative and not exclusive of any other
          right or remedy any party may have. No failure or delay by any party
          hereto in exercising any right, power or privilege shall operate as a
          waiver of any such right, power or privilege, except as expressly set
          forth in this Agreement. No waiver of any default shall constitute a
          waiver of any other or any subsequent default. No single or partial
          exercise of any right, power or privilege shall preclude the further
          or other exercise of the same or other right, power or privilege.

     13.3 Governing Law.  THIS AGREEMENT AND ITS VALIDITY, CONSTRUCTION AND
          -------------                                                  
          PERFORMANCE SHALL BE GOVERNED IN ALL RESPECTS BY THE LAWS OF THE STATE
          OF DELAWARE WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAW.

     13.4 Representation by Counsel.  Each party and its counsel cooperated in
          -------------------------                                        
          the drafting and preparation of this Agreement and the documents
          referred to herein. Accordingly, any rule of law or any legal decision
          that would require interpretation of any ambiguities in this Agreement
          against the party that drafted it is of no application and is hereby
          expressly waived by each party.

     13.5 Benefit of Parties; Assignment.  This Agreement shall be binding upon
          ------------------------------                                  
          and shall inure to the benefit of the parties hereto and their
          respective successors, legal representatives and permitted assigns.
          The Agreement may not be assigned by any party except with the prior
          written consent of other parties hereto. Nothing herein contained
          shall confer or is intended to confer on any third party or entity
          which is not a party to this Agreement any rights under this
          Agreement, except as provided in Section 11.8.

     13.6 Expenses.  Except as specifically provided otherwise in this

          Agreement, or as otherwise agreed in writing by any party (e.g., the
          Purchaser has previously agreed, in writing, to pay certain fees to
          Richard A. Eisner & Company, LLP, Trager & Trager, P.C. and Neal
          Simmons, CPA, and the failure by the Purchaser to timely pay any such
          sums in accordance with said agreement shall be a material default by
          the Purchaser under this Agreement), each party will pay its own
          expenses incident to this Agreement and the transactions contemplated
          hereby, including legal and accounting fees.

     After the date hereof, the Company shall not incur any material fees or
expenses on behalf of the Stockholders in connection with the transactions
contemplated by this Agreement; provided, however that nothing contained in this
or any other Section of this Agreement shall prohibit or affect the right of the
Company to pay, after the date hereof and prior to or at the Closing, any of the
following: (i) accounting and other reasonable fees to Richard A. Eisner &
Company, LLP and/or Neal Simmons, CPA; or (ii) up to a total of $50,000 of the
legal fees incurred by the Company and/or the Stockholders in connection with
this Agreement and/or the transactions contemplated hereby which are payable to
Berkowitz & Balbirer, P.C. and/or Trager & Trager, P.C.

          which shall be deemed to be an original instrument and all of which
          shall constitute one and the same instrument.

          only and shall not constitute a part hereof.

       Shares in the capital stock of the Corporation shall be transferred only
on the books of the Corporation by the holder thereof in person, or by his
attorney, upon surrender and cancellation of certificates for a like number of
shares. The delivery of a certificate of stock of this Corporation to a bona
fide purchaser or pledgee for value, together with a written transfer of the
same or a written power of attorney to sell, assign, and transfer the same,
signed by the owner of the certificate, shall be a sufficient delivery to

determined; and only stockholders of record on such day shall be entitled to
notice or to vote at such meeting, or to receive dividends, as the case may be.

such Registrar.

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

       The Board of Directors may restrict any stock issued by giving the
Corporation or any stockholder "first right of refusal to purchase" the stock,
by making the stock redeemable or by restricting the transfer of the stock,
under such terms and in such manner as the directors may deem necessary and as
are not inconsistent with the Articles of Incorporation or the laws of the State
of Colorado. Any stock so restricted must carry a stamped legend setting out the
restriction or conspicuously noting the restriction and stating where it may be
found in the records of the Corporation.

                               WARRANT AGREEMENT


     This WARRANT AGREEMENT ("Agreement") dated as of June ___, 1998 is by
and between among Communications Systems International, Inc., a Colorado
corporation (the "Company"), and Cruttenden Roth Incorporated and Cohig & 
Associates, Inc. ( the "Representatives").

     WHEREAS, the Representatives have agreed pursuant to the Underwriting
Agreement dated June ___, 1998 (the "Underwriting Agreement") to act as the
representative of the several underwriters in connection with the proposed
public offering by the Company of up to ________ shares of Common Stock, _______
of such shares covered by an over-allotment option (the "Public Offering"); and

     WHEREAS, pursuant to Section 5(n) of the Underwriting Agreement, the
Company has agreed to issue warrants to the Representatives (the "Warrants") to
purchase, at a price of $0.001 per warrant, up to an aggregate of ______ shares
(hereinafter, and as the number thereof may be adjusted hereto, the "Warrant
Shares"), of the Company's Common Stock, no par value per share (the "Common
Stock"), each Warrant initially entitling the holder thereof to purchase one
share of Common Stock.

     NOW, THEREFORE, in consideration of the premises and the mutual agreements
herein and in the Underwriting Agreement the parties hereto agree as follows:

     1.  ISSUANCE OF WARRANTS: FORM OF WARRANT.  The Company will issue and
         -------------------------------------                             
deliver to the Representatives, Warrants to purchase ________ Warrant Shares on
the Closing Date referred to in the Underwriting Agreement in consideration for,
and as part of the Representatives' compensation in connection with, the
Representatives acting as the representative of the several underwriters for the
Public Offering pursuant to the Underwriting Agreement. The text of the Warrants
and of the form of election to purchase shares shall be substantially as set
forth in Exhibit A attached hereto. The Warrants shall be executed on behalf of
the Company by the manual or facsimile signature of the present or any future
Chairman of the Board, President or Chief Executive Officer of the Company,
under its corporate seal, affixed or in facsimile, attested by the manual or
facsimile signature of the Secretary or an Assistant Secretary of the Company.

     Warrants bearing the manual or facsimile signatures of individuals who were
at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any one of them shall have ceased to
hold such offices prior to the delivery of such Warrants or did not hold such
offices on the date of this Agreement. Warrants shall be dated as of the date of
execution thereof by the Company either upon initial issuance or upon division,
exchange, substitution or transfer.

     2.  REGISTRATION.  The Warrants shall be numbered and shall be registered
         ------------                                                         
on the books of the Company (the "Warrant Register") as they are issued. The
Company shall be entitled to treat the registered holder of any Warrant on the
Warrant Register (the "Holder") as the owner in fact therefor for all purposes
and shall not be bound to recognize any equitable or other claim to or interest
in such Warrant on the part of any other person, and shall not be liable for any
registration or transfer of Warrants which are registered or are to be
registered in the name of a fiduciary or the nominee of a fiduciary unless made
with the actual knowledge that a fiduciary or nominee is committing a breach of
trust in requesting such registration or transfer, or with the knowledge of
<PAGE>
 
such facts that its participation therein amounts to bad faith.  Warrants to
purchase the initial Warrant Shares shall be registered initially in the names
of "Cruttenden Roth Incorporated" or "Cohig & Associates, Inc." or in such
other denominations as the Representatives may request in writing to the
Company.

     3.  EXCHANGE OF WARRANT CERTIFICATES.  Subject to any restriction upon
         --------------------------------                                  
transfer set forth in this Agreement, each Warrant certificate may be exchanged
for another certificate or certificates entitling the Holder thereof to purchase
a like aggregate number of Warrant Shares as the certificate or certificates
surrendered then entitled such Holder to purchase. Any Holder desiring to
exchange a Warrant certificate or certificates shall make such request in
writing delivered to the Company, and shall surrender, properly endorsed, the
certificate or certificates to be so exchanged. Thereupon, the Company shall
execute and deliver to the person entitled thereto a new Warrant certificate or
certificates, as the case may be, as so requested.

     4.  TRANSFER OF WARRANTS.  Until June ___, 1999, the Warrants will not
         --------------------                                                  
be sold, transferred, assigned or hypothecated except to bona fide officers of
the Representatives who agree in writing to be bound by the terms hereof. The
Warrants shall be transferable only on the Warrant Register upon delivery
thereof duly endorsed by the Holder or by the Holder's duly authorized attorney
or representative, or accompanied by proper evidence of succession, assignment
or authority to transfer. In all cases of transfer by an attorney, the original
power of attorney, duly approved, or an official copy thereof, duly certified,
shall be deposited with the Company. In case of transfer by executors,
administrators, guardians or other legal representatives, duly authenticated
evidence of their authority shall be produced and may be required to be
deposited with the Company in its discretion. Upon any registration of transfer,
the Company shall deliver a new Warrant or Warrants to the person entitled
thereto.

     5.  TERM OF WARRANTS; EXERCISE OF WARRANTS.
         -------------------------------------- 

               5.1(a) Each Warrant entitles the registered owner thereof to
         purchase one share of Common Stock at any time from 10:00 a.m.,
         Mountain time, on June ___, 1999 (the "Initiation Date") until 6:00
         p.m., Mountain time, on December ___, 2003 (the "Expiration Date") at a
         purchase price of [$_____], subject to adjustment (the "Warrant
         Price"). Payment may be in cash, wire transfer or by check payable to
         the order of the Company. Notwithstanding the foregoing, if at 6:00
         p.m., Mountain time on the Expiration Date, any Holder or Holders of
         the Warrants have not exercised their Warrants and the Closing Price
         (as defined below) for the Common Stock on the Expiration Date is
         greater than the Warrant Price, then each such unexercised Warrant
         shall be automatically converted into a number of shares of Common
         Stock of the Company equal to: (A) the number of shares of Common Stock
         then issuable upon exercise of a Warrant multiplied by (B) a fraction
         (1) the numerator of which is the difference between the Closing Price
         for the Common Stock on the Expiration Date and the Warrant Price and
         (2) the denominator of which is the Closing Price for the Common Stock
         on the Expiration Date.

               5.1(b) Upon written request of any Holder, and in lieu of payment
         of the Warrant Price, any Holder may exercise the Warrants (or any
         portion thereof held by such Holder) for and receive the number of
         Warrant Shares equal to a fraction, the numerator of which equals (i)
         the difference between the Warrant Price per share and

                                      -2-
<PAGE>
 
          the average of the Closing Price of the Common Stock for the ten (10)
          trading days preceding the date of exercise (the "Current Market
          Price"), multiplied by (ii) the number of Warrant Shares to be
          purchased; and the denominator of which equals the Current Market
          Price.  This provision shall apply solely in the event a public
          trading market exists with respect to the Common Stock.  The rights
          granted to each Holder in this Section 5.1(b) are exercisable at any
          time after the Initiation Date and up to the Expiration Date at the
          sole election of each Holder.  The provisions of Section 5.1(a) will
          apply as of the Expiration Date.

          5.2  The Warrant Price and the number of Warrant Shares issuable upon
     exercise of Warrants are subject to adjustment upon the occurrence of
     certain events, pursuant to the provisions of Section 11 of this Agreement.
     Subject to the provisions of this Agreement, each Holder of Warrants shall
     have the right, which may be exercised as expressed in such Warrants, to
     purchase from the Company (and the Company shall issue and sell to such
     Holder of Warrants) the number of fully paid and nonassessable Warrant
     Shares specified in such Warrants, upon surrender to the Company, or its
     duly authorized agent, of such Warrants, with the form of election to
     purchase on the reverse thereof duly filled in and signed, and upon payment
     to the Company of the Warrant Price, as adjusted in accordance with the
     provisions of Section 11 of this Agreement, for the number of Warrant
     Shares in respect of which such Warrants are then exercised.  All Warrants
     surrendered in the exercise of the rights thereby evidenced shall be
     cancelled.  No adjustment shall be made for any dividends on any Warrant
     Shares of stock issuable upon exercise of a Warrant.

          5.3  Upon such surrender of Warrants, and payment of the Warrant Price
     as aforesaid, the Company shall issue and cause to be delivered with all
     reasonable dispatch to or upon the written order of the Holder of such
     Warrants and in such name or names as such registered Holder may designate,
     a certificate or certificates for the number of full Warrant Shares so
     purchased upon the exercise of such Warrants, together with cash, as
     provided in Section 12 of this Agreement, in respect of any fraction of a
     share otherwise issuable upon such surrender and, if the number of Warrants
     represented by a Warrant Certificate shall not be exercised in full, a new
     Warrant Certificate, executed by the Company for the balance of the number
     of whole Warrant Shares represented by the Warrant Certificate.

          5.4  If permitted by applicable law, such certificate or certificates
     shall be deemed to have been issued and any person so designated to be
     named therein shall be deemed to have become a holder of record of such
     shares as of the date of the surrender of such Warrants and payment of the
     Warrant Price as aforesaid. The rights of purchase represented by the
     Warrants shall be exercisable, at the election of the registered Holders
     thereof, either as an entirety or from time to time for only part of the
     shares specified therein.

     6.   COMPLIANCE WITH GOVERNMENT REGULATIONS.  The Company covenants that if
          --------------------------------------                                
any shares of Common Stock required to be reserved for purposes of exercise or
conversion of Warrants require, under any Federal or state law or applicable
governing rule or regulation of any national securities exchange, registration
with or approval of any governmental authority before such shares may be issued
upon exercise, the Company will in good faith and as expeditiously as possible
endeavor to cause such shares to be duly registered or approved, as the case may
be; provided that (except to the extent legally permissible with respect to
Warrants of which the Representatives is the

                                      -3-
<PAGE>
 
Holder) in no event shall such shares of Common Stock be issued, and the Company
is hereby authorized to suspend the exercise of all Warrants, for the period
during which such registration, approval or listing is required but not in
effect.

     7.   PAYMENT OF TAXES. The Company will pay all documentary stamp taxes, if
          ----------------                                                      
any, attributable to the initial issuance of Warrant Shares upon the exercise of
Warrants; provided that the Company shall not be required to pay any tax or
taxes which may be payable in respect of any transfer involved in the issue or
delivery of any Warrants or certificate for Warrant Shares in a name other than
that of the registered Holder of such Warrants or for any Warrants issued
pursuant to Section 8 of this Agreement.

     8.   MUTILATED OR MISSING WARRANTS.  In case any of the Warrants shall be
          -----------------------------                                       
mutilated, lost, stolen or destroyed, the Company shall issue and deliver in
exchange and substitution for and upon cancellation of the mutilated Warrant, or
in lieu of and substitution for the Warrant lost, stolen or destroyed, a new
Warrant of like tenor and representing an equivalent right or interest; but only
upon receipt of evidence reasonably satisfactory to the Company of such loss,
theft or destruction of such Warrant and, if requested, indemnity or bond also
reasonably satisfactory to the Company. An applicant for such substitute
Warrants shall also comply with such other reasonable regulations and pay such
other reasonable charges as the Company may prescribe.

     9.   RESERVATION OF WARRANT SHARES.  There have been reserved out of the
          -----------------------------                                      
authorized and unissued shares of Common Stock a number of shares sufficient to
provide for the exercise of the rights of purchase represented by the Warrants
and the transfer agent for the Common Stock ("Transfer Agent") and every
subsequent Transfer Agent for any shares of the Company's capital stock issuable
upon the exercise of any of the rights of purchase aforesaid are hereby
irrevocably authorized and directed at all times until the Expiration Date to
reserve such number of authorized and unissued shares as shall be required for
such purpose. The Company will keep a copy of this Agreement on file with the
Transfer Agent and with every subsequent Transfer Agent for any shares of the
Company's capital stock issuable upon the exercise of the rights of purchase
represented by the Warrants. The Company will supply such Transfer Agent with
duly executed stock certificates for such purposes and will itself provide or
otherwise make available any cash which may be issuable as provided in Section
12 of this Agreement. The Company will furnish to such Transfer Agent a copy of
all notices of adjustments, and certificates related thereto, transmitted to
each Holder pursuant to Section 11.2 of this Agreement.

     10.  OBTAINING STOCK EXCHANGE LISTINGS.  The Company will from time to time
          ---------------------------------                                     
take all action which may be necessary so that the Warrant Shares, immediately
upon their issuance upon the exercise of Warrants, will be listed on the
principal securities exchanges and markets within the United States of America,
if any, on which other shares of Common Stock are then listed.

     11.  ADJUSTMENT OF WARRANT PRICE AND NUMBER OF WARRANT SHARES.  The number
          --------------------------------------------------------             
and kind of securities purchasable upon the exercise of each Warrant and the
Warrant Price shall be subject to adjustment from time to time upon the
happening of certain events as hereinafter defined. For purposes of this Section
11, "Common Stock" means shares now or hereafter authorized of any class of
common stock of the Company and any other stock of the Company, however
designated, that has the right (subject to any prior rights of any class or
series of preferred stock) to participate in any distribution of the assets or
earnings of the Company without limit as to per share amount.

                                      -4-
<PAGE>
 
          11.1  MECHANICAL ADJUSTMENTS.  The number of Warrant Shares
     purchasable upon the exercise of each Warrant and the Warrant Price shall
     be subject to adjustment as follows:

               (a) In case the Company shall (i) pay a dividend in shares of
          Common Stock or make a distribution in shares of Common Stock, (ii)
          subdivide its outstanding shares of Common Stock, (iii) combine its
          outstanding shares of Common Stock or (iv) issue by reclassification
          of its shares of Common Stock other securities of the Company
          (including any such reclassification in connection with a
          consolidation or merger in which the Company is the surviving
          corporation), the number of Warrant Shares purchasable upon exercise
          of each Warrant immediately prior thereto shall be adjusted so that
          the Holder of each Warrant shall be entitled to receive the kind and
          number of Warrant Shares or other securities of the Company which the
          holder would have owned or would have been entitled to receive after
          the happening of any of the events described above, had such Warrants
          been exercised immediately prior to the happening of such event or any
          record date with respect thereto. An adjustment made pursuant to this
          paragraph (a) shall become effective immediately after the effective
          date of such event retroactive to the record date, if any, for such
          event. Such adjustment shall be made successively whenever any event
          listed above shall occur.

               (b) In case the Company shall distribute to all holders of its
          shares of Common Stock (including any such distribution made in
          connection with a consolidation or merger in which the Company is the
          surviving corporation) evidences of its indebtedness or assets
          (including securities, but excluding cash dividends or distributions
          payable out of consolidated earnings or earned surplus and dividends
          or distributions referred to in paragraph (a) above or in the
          paragraph immediately following this paragraph) or rights, options or
          warrants, or convertible or exchangeable securities containing the
          right to subscribe for or purchase shares of Common Stock, then in
          each case the number of Warrant Shares thereafter purchasable upon the
          exercise of each Warrant shall be determined by multiplying the number
          of Warrant Shares theretofore purchasable upon the exercise of each
          Warrant by a fraction, the numerator of which shall be the then
          current market price per share of Common Stock (as defined in
          paragraph (c) below) on the date of such distribution, and the
          denominator of which shall be the then current market price per share
          of Common Stock on the date of such distribution, less the then fair
          value (as reasonably determined by the Board of Directors of the
          Company) of the portion of the assets or evidences of indebtedness so
          distributed or of such subscription rights, options or warrants, or of
          such convertible or exchangeable securities applicable to one share of
          Common Stock. Subject to paragraph (d) below, such adjustment shall be
          made whenever any such distribution is made and shall become effective
          on the date of distribution retroactive to the record date for the
          determination of stockholders entitled to receive such distribution.

               In the event of a distribution by the Company to all holders of
          its shares of Common Stock of a subsidiary or securities convertible
          into or exercisable for such stock, then in lieu of an adjustment in
          the number of Warrant Shares purchasable upon the exercise of each
          Warrant, the Holder of each Warrant, upon the exercise thereof at any
          time after such distribution, shall be entitled to receive from the

                                      -5-
<PAGE>
 
          Company, such subsidiary or both, as the Company shall determine, the
          stock or other securities to which such Holder would have been
          entitled if such Holder had exercised such Warrant immediately prior
          thereto, all subject to further adjustment as provided in this Section
          11.1; provided, however, that no adjustment in respect of dividends or
          interest on such stock or other securities shall be made during the
          term of a Warrant or upon the exercise of a Warrant.

               (c) For the purpose of any computation under paragraph (b) of
          this Section, the current market price per share of Common Stock at
          any date shall be the average of the daily Closing Prices for 20
          consecutive trading days commencing 30 trading days before the date of
          such computation. The selling price for each day (the "Closing Price")
          shall be the last such reported sales price regular way or, in case no
          such reported sale takes place on such day, the average of the closing
          bid and asked prices regular way for such day, in each case on the
          principal national securities exchange on which the shares of Common
          Stock are listed or admitted to trading or, if not listed or admitted
          to trading, the average of the closing bid and asked prices of the
          Common Stock in the over-the counter market as reported by the Nasdaq
          National Market System or Nasdaq SmallCap System or if not approved
          for quotation on the Nasdaq National Market System or Nasdaq SmallCap
          Market, the average of the closing bid and asked prices as furnished
          by two members of the National Association of Securities Dealers, Inc.
          selected from time to time by the Company for that purpose.

               (d) No adjustment in the number of Warrant Shares purchasable
          hereunder shall be required unless such adjustment would require an
          increase or decrease of at least one percent (1%) in the number of
          Warrant Shares purchasable upon the exercise of each Warrant;
          provided, however, that any adjustments which by reason of this
          paragraph (d) are not required to be made shall be carried forward and
          taken into account in any subsequent adjustment. All calculations
          shall be made to the nearest one-thousandth of a share.

               (e) Whenever the number of Warrant Shares purchasable upon the
          exercise of each Warrant is adjusted, as herein provided, the Warrant
          Price payable upon exercise of each Warrant shall be adjusted by
          multiplying such Warrant Price immediately prior to such adjustment by
          a fraction, the numerator of which shall be the number of Warrant
          Shares purchasable upon the exercise of each Warrant immediately prior
          to such adjustment, and the denominator of which shall be the number
          of Warrant Shares purchasable immediately thereafter.

               (f) No adjustment in the number of Warrant Shares purchasable
          upon the exercise of each Warrant need be made under paragraph (b) if
          the Company issues or distributes to each Holder of Warrants the
          rights, options, warrants or convertible or exchangeable securities,
          or evidences of indebtedness or assets referred to in those paragraphs
          which each Holder of Warrants would have been entitled to receive had
          the Warrants been exercised prior to the happening of such event or
          the record date with respect thereto. No adjustment need be made for a
          change in the par value of the Warrant Shares.

                                      -6-
<PAGE>
 
               (g) In the event that at any time, as a result of an adjustment
          made pursuant to paragraph (a) above, the Holders shall become
          entitled to purchase any securities of the Company other than shares
          of Common Stock, thereafter the number of such other shares so
          purchasable upon exercise of each Warrant and the Warrant Price of
          such shares shall be subject to adjustment from time to time in a
          manner and on terms as nearly equivalent as practicable to the
          provisions with respect to the Warrant Shares contained in this
          Section 11, and the other provisions of this Agreement, with respect
          to the Warrant and Warrant Shares, shall apply as nearly equivalent as
          practicable on like terms to such other securities.

               (h) Upon the expiration of any rights, options, warrants or
          conversion or exchange privileges for which an adjustment was made
          hereunder, if any thereof shall not have been exercised, the Warrant
          Price and the number of shares of Common Stock purchasable upon the
          exercise of each Warrant shall, upon such expiration, be readjusted
          and shall thereafter be such as it would have been had it been
          originally adjusted (or had the original adjustment not been required,
          as the case may be) as if (i) the only shares of Common Stock so
          issued were the shares of Common Stock, if any, actually issued or
          sold upon the exercise of such rights, options, warrants or conversion
          or exchange rights and (ii) such shares of Common Stock, if any, were
          issued or sold for the consideration actually received by the Company
          upon such exercise plus the aggregate consideration, if any, actually
          received by the Company for the issuance, sale or grant of all such
          rights, options, warrants or conversion or exchange rights whether or
          not exercised; provided, however, that no such readjustment shall have
          the effect of increasing the Warrant Price or decreasing the number of
          shares of Common Stock purchasable upon the exercise of each Warrant
          by an amount in excess of the amount of the adjustment initially made
          in respect to the issuance, sale or grant of such rights, options,
          warrants or conversion or exchange rights.

          11.2  NOTICE OF ADJUSTMENT.  Whenever the number of Warrant Shares
     purchasable upon the exercise of each Warrant or the Warrant Price of such
     Warrant Shares is adjusted, as herein provided, the Company shall promptly
     mail by first class, postage prepaid, to each Holder notice of such
     adjustment or adjustments and a certificate of a firm of independent public
     accountants selected by the Board of Directors of the Company (who may be
     the regular accountants employed by the Company) setting forth the number
     of Warrant Shares purchasable upon the exercise of each Warrant and the
     Warrant Price of such Warrant Shares after such adjustment, setting forth a
     brief statement of the facts requiring such adjustment and setting forth
     the computation by which such adjustment was made.

          11.3  NO ADJUSTMENT FOR DIVIDENDS.  Except as provided in Section
     11.1, no adjustments in respect of any dividends shall be made during the
     term of a Warrant or upon the exercise of a Warrant.

          11.4  PRESERVATION OF PURCHASE RIGHTS UPON MERGER, CONSOLIDATION ETC.
     In case of any consolidation of the Company with or merger of the Company
     into another corporation or in case of any sale, transfer or lease to
     another corporation of all or substantially all the property of the
     Company, the Company or such successor or purchasing corporation, as the
     case may be, shall execute with each Holder an agreement that each

                                      -7-
<PAGE>
 
     Holder shall have the right thereafter upon payment of the Warrant Price in
     effect immediately prior to such action to purchase upon exercise of each
     Warrant the kind and amount of shares and other securities, cash and
     property which he would have owned or would have been entitled to receive
     after the happening of such consolidation, merger, sale, transfer or lease
     had such Warrant been exercised immediately prior to such action; provided,
     however, that no adjustment in respect of dividends, interest or other
     income on or from such shares or other securities, cash and property shall
     be made during the term of a Warrant or upon the exercise of a Warrant.
     Such agreement shall provide for adjustments, which shall be as nearly
     equivalent as may be practicable to the adjustments provided for in this
     Section 11.  The provisions of this Section 11.4 shall similarly apply to
     successive consolidations, mergers, sales transfer or leases.

          11.5  STATEMENTS ON WARRANTS.  Irrespective of any adjustments in the
     Warrant Price or the number or kind of shares purchasable upon the exercise
     of the Warrants, Warrants theretofore or thereafter issued may continue to
     express the same price and number and kind of shares as are stated in the
     Warrants initially issuable pursuant to this Agreement.

     12.  FRACTIONAL INTERESTS. The Company shall not be required to issue
          --------------------                                            
fractional Warrant Shares on the exercise of Warrants. If more than one Warrant
shall be presented for exercise in full at the same time by the same holder, the
number of full Warrant Shares which shall be issuable upon the exercise thereof
shall be computed on the basis of the aggregate number of Warrant Shares
purchasable on exercise of the Warrants so presented. If any fraction of a
Warrant Share would, except for the provisions of this Section 12, be issuable
on the exercise of any Warrant (or specified portion thereof), the Company shall
pay an amount in cash equal to the closing price for one share of the Common
Stock, as defined in paragraph (c) of Section 11.1, on the trading day
immediately preceding the date the Warrant is presented for exercise, multiplied
by such faction.

     13.  REGISTRATION UNDER THE SECURITIES ACT OF 1933.
          --------------------------------------------- 

          (a) The Holder understands that the Warrants and the Warrant Shares
     purchasable hereunder constitute "Restricted Securities" under the federal
     securities laws since they are, or will be, acquired from the Company in
     transactions not involving a public offering and accordingly may not, under
     such laws and applicable regulations, be resold or transferred without
     registration under the Act or an applicable exemption from such
     registration.  In this connection, the Holder acknowledges that Rule 144 of
     the Commission may not in the future be available for resales of the
     Warrants or Warrant Shares.  Unless the Warrant Shares are subsequently
     registered pursuant to Section 15, the Holder further acknowledges that the
     securities legend in Section 14 hereof shall be placed on any Warrant
     Shares issued to the Holder upon exercise of this Warrant.

          (b) Unless a current registration statement under the Act shall be in
     effect with respect to the securities to be issued upon exercise of this
     Warrant, the Holder covenants and agrees that, at the time of exercise
     hereof, it will deliver to the Company a written certification executed by
     the Holder that the securities acquired by him upon exercise hereof are for
     the account of such Holder and acquired for investment purposes only and
     that such securities are not acquired with a view to, or for sale in
     connection with, any distribution thereof in violation of applicable
     securities law.

                                      -8-
<PAGE>
 
          (c) Holder hereby agrees not to make any disposition of any Warrant
     Shares purchased hereunder unless and until:

               (i) Holder shall have complied with all requirements of this
          Warrant applicable to the disposition of the Shares; and

               (ii) Holder shall have provided the Company with written
          assurances, in form and substance reasonably satisfactory to legal
          counsel of the Company, that (i) the proposed disposition does not
          require registration of the Warrant Shares under the Act or (ii) all
          appropriate action necessary for compliance with registration
          requirements of the Act or of any exemption from registration
          available under the Act has been taken.

          (d) The Company shall not be required to transfer on its books any
     Warrant Shares which have been sold or transferred in violation of the
     provisions of this Section 13.

     14.  CERTIFICATE TO BEAR LEGENDS.  The Warrant shall be subject to a  stop-
          ---------------------------                                          
transfer order and the certificate or certificates therefore shall bear the
following legend:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAW.
     THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED UNTIL
     ___________, 1999.  THEREAFTER, SAID SECURITIES MAY NOT BE SOLD OR
     TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM
     UNDER SAID ACT.

     The Warrant Shares or other securities issued upon exercise of the Warrant
shall be subject to a stop-transfer order and the certificate or certificates
evidencing any such Warrant Shares or securities shall bear the following
legend:

     THE SHARES OR OTHER SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT
     BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE
     SECURITIES LAW.  THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE
     TRANSFERRED UNTIL ________, 1999.  THEREAFTER, SAID SECURITIES MAY NOT BE
     SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION
     THEREFROM UNDER SAID ACT.

     15.  REGISTRATION RIGHTS.
          ------------------- 

          15.1  DEMAND REGISTRATION RIGHTS.  The Company covenants and agrees
     with the Representatives and any subsequent Holders of the Warrants and/or
     Warrants Shares that, on two occasions, within 60 days after receipt of a
     written request from the Representatives or from Holders of more than 50%
     in interest of the aggregate of Warrants and/or Warrant Shares issued
     pursuant to this Agreement that the Representatives or such Holders of the
     Warrants and/or Warrant Shares desire and intend to transfer more than 50%
     in interest of the aggregate number of the Warrant Shares under such
     circumstances that a public offering, within the meaning of the Act, will
     be involved, the Company shall, on those two occasions, file a registration
     statement (and use its reasonable best efforts to cause such registration

                                      -9-
<PAGE>
 
     statement to become effective under the Act at the Company's expense) with
     respect to the offering and sale or other disposition of the Warrant Shares
     (the "Offered Warrant Shares"); provided, however, that the Company shall
     have no obligation to comply with the foregoing provisions of this Section
     15.1 if in the opinion of counsel to the Company reasonably acceptable to
     the Holder or Holders, from whom such written requests have been received,
     registration under the Act is not required for the transfer of the Offered
     Warrant Shares in the manner proposed by such person or persons or that a
     post-effective amendment to an existing registration statement would be
     legally sufficient for such transfer (in which latter event the Company
     shall promptly file such post-effective amendment (and use its reasonable
     best efforts to cause such amendment to become effective under the Act)).
     Notwithstanding the foregoing, the Company shall not be obligated to file a
     registration statement with respect to the Offered Warrant Shares on more
     than two occasions.

          The Company may defer the preparation and filing of a registration
     statement for up to 120 days after the request for registration is made if
     the Board of Directors determines in good faith that such registration or
     post-effective amendment would materially adversely affect or otherwise
     materially interfere with a proposed or pending transaction by the Company,
     including without limitation a material financing or a corporate
     reorganization, or during any period of time in which the Company is in
     possession of material inside information concerning the Company or its
     securities, which information the Company determines in good faith is not
     ripe for disclosure.

          The Company shall not honor any request to register Warrant Shares
     pursuant to this Section 15.1 received later than five (5) years from the
     effective date of the Company's registration statement on Form S-1 (File
     No. 333-47045) (the "Effective Date"). The Company shall not be required
     (i) to maintain the effectiveness of the registration statement beyond the
     earlier to occur of 90 days after the effective date of the registration
     statement or the date on which all of the Offered Warrant Shares have been
     sold (the "Termination Date"); provided, however, that if at the
     Termination Date the Offered Warrant Shares are covered by a registration
     statement which also covers other securities and which is required to
     remain in effect beyond the Termination Date, the Company shall maintain in
     effect such registration statement as it relates to Offered Warrant Shares
     for so long as such registration statement (or any substitute registration
     statement) remains or is required to remain in effect for any such other
     securities, or (ii) to cause any registration statement with respect to the
     Warrant Shares to become effective prior to the Initiation Date. All
     expenses of registration pursuant to this Section 15.1 shall be borne by
     the Company (excluding underwriting discounts and commissions on Warrant
     Shares not sold by the Company).

          The Company shall be obligated pursuant to this Section 15.1 to
     include in the registration statement Warrant Shares that have not yet been
     purchased by a Holder of Warrants so long as such Holder of Warrants
     submits an undertaking to the Company that such Holder intends to exercise
     Warrants representing the number of Warrant Shares to be included in such
     registration statement prior to the consummation of the public offering
     with respect to such Warrant Shares. In addition, such Holder of Warrants
     is permitted to pay the Company the Warrant Price for such Warrant Shares
     upon the consummation of the public offering with respect to such Warrant
     Shares.

                                      -10-
<PAGE>
 
          15.2  PIGGY-BACK REGISTRATION RIGHTS.  The Company covenants and
     agrees with the Holders and any subsequent Holders of the Warrants and/or
     Warrant Shares that in the event the Company proposes to file a
     registration statement under the Act with respect to any class of security
     (other than in connection with an exchange offer, a non-cash offer or a
     registration statement on Form S-4 or Form S-8 or other unsuitable
     registration statement form) which becomes or which the Company believes
     will become effective at any time after the Initiation Date then the
     Company shall in each case give written notice of such proposed filing to
     the Holders of Warrants and Warrant Shares at least 30 days before the
     proposed filing date and such notice shall offer to such Holders the
     opportunity to include in such registration statement such number of
     Warrant Shares as they may request, unless, in the opinion of counsel to
     the Company reasonably acceptable to any such holder of Warrants or Warrant
     Shares who wishes to have Warrant Shares included in such registration
     statement, registration under the Act is not required for the transfer of
     such Warrant Shares in the manner proposed by such Holders. The Company
     shall not honor any such request to register any such Warrant Shares if the
     request is received later than six (6) years from the Effective Date, and
     the Company shall not be required to honor any request (a) to register any
     such Warrant Shares if the Company is not notified in writing of any such
     request pursuant to this Section 15.2 within at least 20 days after the
     Company has given notice to the Holders of the filing, or (b) to register
     Warrant Shares that represent in the aggregate fewer than 50% of the
     aggregate number of Warrant Shares. The Company shall permit, or shall
     cause the managing underwriter of a proposed offering to permit, the
     Holders of Warrant Shares requested to be included in the registration (the
     "Piggy-back Shares ") to include such Piggy-back Shares in the proposed
     offering on the same terms and conditions as applicable to securities of
     the Company included therein or as applicable to securities of any person
     other than the Company and the Holders of Piggy-back Shares if the
     securities of any such person are included therein. Notwithstanding the
     foregoing, if any such managing underwriter shall advise the Company in
     writing that it believes that the distribution of all or a portion of the
     Piggy-back Shares requested to be included in the registration statement
     concurrently with the securities being registered by the Company would
     materially adversely affect the distribution of such securities by the
     Company for its own account, then the Holders of such Piggy-back Shares
     shall delay their offering and sale of Piggyback Shares (or the portion
     thereof so designated by such managing underwriter) for such period, not to
     exceed 120 days, as the managing underwriter shall request; provided that
     no such delay shall be required as to Piggy-back Shares if any securities
     of the Company are included in such registration statement for the account
     of any person other than the Company and the Holders of Piggy-back Shares.
     In the event of such delay, the Company shall file such supplements, post-
     effective amendments or separate registration statements, and take any such
     other steps as may be necessary to permit such Holders to make their
     proposed offering and sale for a period of 90 days immediately following
     the end of such period of delay ("Piggy-back Termination Date"); provided,
     however, that if at the Piggy-back Termination Date the Piggyback Shares
     are covered by a registration statement which is, or required to remain, in
     effect beyond the Piggy-back Termination Date, the Company shall maintain
     in effect the registration statement as it relates to the Piggy-back Shares
     for so long as such registration statement remains or is required to remain
     in effect for any of such other securities. All expenses of registration
     pursuant to this Section 15.2 shall be borne by the Company, except that
     underwriting commissions and expenses attributable to the Piggy-back Shares
     and fees and disbursements of counsel (if any) to the Holders requesting
     that such Piggy-back Shares be offered will be borne by such Holders.

                                      -11-
<PAGE>
 
          The Company shall be obligated pursuant to this Section 15.2 to
     include in the Piggy-back Offering, Warrant Shares that have not yet been
     purchased by a holder of Warrants so long as such Holder of Warrants
     submits an undertaking to the Company that such Holder intends to exercise
     Warrants representing the number of Warrant Shares to be included in such
     Piggy-back Offering prior to the consummation of such Piggy-back Offering.
     In addition, such Holder of Warrants is permitted to pay the Company the
     Warrant Price for such Warrant Shares upon the consummation of the Piggy-
     back Offering.

          If the Company decides not to proceed with a Piggy-back Offering, the
     Company has no obligation to proceed with the offering of the Piggy-back
     Shares, unless the Holders of the Warrants and/or Warrant Shares otherwise
     comply with the provisions of Section 15.1 hereof (without regard to the 60
     days' written request required thereby). Notwithstanding any of the
     foregoing contained in this Section 15.2, the Company's obligation to offer
     registration rights to the Piggy-back Shares pursuant to this Section 15.2
     shall terminate two (2) years after the Expiration Date.

          15.3  In connection with the registration of Warrants Shares in
     accordance with Section 15.1 and 15.2 above, the Company agrees to:

               (a) Use its reasonable best efforts to register or qualify the
          Warrant Shares for offer or sale under the state securities or Blue
          Sky laws of such states which the Holders of such Warrant Shares shall
          designate, until the dates specified in Section 15.1 and 15.2 above in
          connection with registration under the Act; provided, however, that in
          no event shall the Company be obligated to quality to do business in
          any jurisdiction where it is not now so qualified or to take any
          action which would subject it to general service of process in any
          jurisdiction where it is not now so subject or to register or get a
          license as a broker or dealer in securities in any jurisdiction where
          it is not so registered or licensed or to register or qualify the
          Warrant Shares for offer or sale under the state securities or Blue
          Sky laws of any state other than the states in which some or all of
          the shares offered or sold in the Public Offering were registered or
          qualified for offer and sale.

                    (b) (i) In the event of any post-effective amendment or
               other registration with respect to any Warrant Shares pursuant to
               Section 15.1 or 15.2 above, the Company will indemnify and hold
               harmless any Holder whose Warrant Shares are being so registered,
               and each person, if any, who controls such Holder within the
               meaning of the Act, against any losses, claims, damages or
               liabilities, joint or several, to which such Holder or such
               controlling person may be subject, under the Act or otherwise,
               insofar as such losses, claims, damages or liabilities (or
               actions in respect thereof) arise out of or are based upon any
               untrue statement or alleged untrue statement of any material fact
               contained, on the effective date thereof, in any such
               registration statement, any preliminary prospectus or final
               prospectus contained therein, or any amendment or supplement
               thereto, or arise out of or are based upon the omission or
               alleged omission to state therein a material fact required to be
               stated therein or necessary to make the statements therein not
               misleading; and will reimburse each such Holder and each such
               controlling person for any legal or other expenses reasonably
               incurred by

                                      -12-
<PAGE>
 
               such Holder or such controlling person in connection with
               investigating or defending any such loss, claim, damage,
               liability or action; provided, however, that the Company will not
               be liable in such case to the extent that any such loss, claim,
               damage or liability arises out of or is based upon any untrue
               statement or alleged untrue statement or omission or alleged
               omission made in any such registration statement, any preliminary
               prospectus or final prospectus, or any amendment or supplement
               thereto, in reliance upon and in conformity with written
               information furnished by such Holder expressly for use in the
               preparation thereof. The Company will not be liable to a claimant
               to the extent of any misstatement corrected or remedied in any
               amended prospectus if the Company timely delivers a copy of such
               amended prospectus to such indemnified person and such
               indemnified person does not timely furnish such amended
               prospectus to such claimant. The Company shall not be required to
               indemnify any Holder or controlling person for any payment made
               to any claimant in settlement of any suit or claim unless such
               payment is approved by the Company.

                    (ii) Each Holder of Warrants and/or Warrant Shares who
               participates in a registration pursuant to Section 15.1 or 15.2
               will indemnify and hold harmless the Company, each of its
               directors, each of its officers who have signed any such
               registration statement, and each person, if any, who controls the
               Company within the meaning of the Act, against any losses,
               claims, damages or liabilities to which the Company, or any such
               director, officer or controlling person may become subject under
               the Act, or otherwise, insofar as such losses, claims, damages or
               liabilities (or actions in respect thereof) arise out of or are
               based upon any untrue or alleged untrue statement of any material
               fact contained in any such registration statement, any
               preliminary prospectus or final prospectus, or any amendment or
               supplement thereto, or arise out of or are based upon the
               omission or the alleged omission to state therein a material fact
               required to be stated therein or necessary to make the statements
               therein not misleading, in each case to the extent, but only to
               the extent, that such untrue statement or alleged untrue
               statement or omission or alleged omission was made in any such
               registration statement, any preliminary prospectus or final
               prospectus, or any amendment or supplement thereto, in reliance
               upon and in conformity with written information furnished by such
               Holder expressly for use in the preparation thereof; and will
               reimburse any legal or other expenses reasonably incurred by the
               Company, or any such director, officer or controlling person in
               connection with investigating or defending any such loss, claim,
               damage, liability or action; provided, however, that the
               indemnity agreement contained in this subparagraph (ii) shall not
               apply to amounts paid to any claimant in settlement of any suit
               or claim unless such payment is first approved by such Holder.

                    (iii)  In order to provide for just and equitable
               contribution in any action in which a claim for indemnification
               is made pursuant to this clause (b)(iii) of Section 15.3 but is
               judicially determined (by the entry of a final judgment or decree
               by a court of competent jurisdiction and the expiration

               of time to appeal or the denial of the last right of appeal) that
               such indemnification may not be enforced in such case
               notwithstanding the fact that this clause (b)(iii) of Section
               15.3 provides for indemnification in such case, all the parties
               hereto shall contribute to the aggregate losses, claims, damages
               or liabilities to which they may be subject (after contribution
               from others) in such proportion so that each Holder whose Warrant
               Shares are being registered is responsible pro rata for the
               portion represented by the public offering price received by such
               Holder from the sale of such Holder's Warrant Shares, and the
               Company is responsible for the remaining portion; provided,
               however, that (i) no Holder shall be required to contribute any
               amount in excess of the public offering price received by such
               Holder from the sale of such Holder's Warrant Shares and (ii) no
               person guilty of a fraudulent misrepresentation (within the
               meaning of Section 11(f) of the Act) shall be entitled to
               contribution from any person who is not guilty of such fraudulent
               misrepresentation. This subsection (b)(iii) shall not be
               operative as to any Holder of Warrant Shares to the extent that
               the Company has received indemnity under this clause (b)(iii) of
               Section 15.3.

     16.  NO RIGHTS AS STOCKHOLDER; NOTICES TO HOLDERS.  Nothing contained in
          --------------------------------------------

the Holders or their transferee(s) the right to vote or to receive dividends or
to consent to or receive notice as stockholders in respect of any meeting of
stockholders for the election of directors of the Company or any other matter or
any rights whatsoever as stockholders of the Company. If, however, at any time
prior to the expiration of the Warrants and prior to their exercise, any of the
following events shall occur:

          (a) the Company shall declare any dividend payable in any securities
     upon its shares of Common Stock or make any distribution (other than a cash
     dividend) to the holders of its shares of Common Stock; or

          (b) the Company shall offer to the holders of its shares of Common
     Stock any additional shares of Common Stock or securities convertible into
     or exchangeable for shares of Common Stock or any right to subscribe to or
     purchase any thereof; or

          (c) a dissolution, liquidation or winding up of the Company (other
     than in connection with a consolidation, merger, sale, transfer or lease of
     all or substantially all of its property, assets and business as an
     entirety) shall be proposed,

then in any one or more of said events the Company shall (i) give notice in
writing of such event to the Holders, as provided in Section 17 hereof and (ii)
if there are more than 100 Holders, issue a press release providing notice of
such event to a national business wire service, such giving of notice and
publication to be completed at least 20 days prior to the date fixed as a record
date or the date of closing the transfer books for the determination of the
stockholders entitled to such dividend, distribution or subscription rights, or
for the determination of stockholders entitled to vote on such proposed
dissolution, liquidation or winding up. Such notice shall specify such record
date or the date of closing the transfer books, as the case may be. Failure to
publish, mail or receive such notice or any defect therein or in the publication
or mailing thereof shall not affect the validity of any action taken in
connection with such dividend, distribution or subscription rights, or such
proposed dissolution, liquidation or winding up.

                              WARRANT CERTIFICATE

                  COMMUNICATIONS SYSTEMS INTERNATIONAL, INC.

          This Warrant Certificate certifies that _____________________, or
registered assigns, is the registered holder of Warrants expiring June __,
2003 (the "Warrants") to purchase Common Stock, no par value per share (the
"Common Stock"), of Communications Systems International, Inc., a Colorado
corporation (the "Company").  Each Warrant entitles the holder upon exercise to
receive from the Company from 10:00 a.m., Mountain time, on June __, 1999
through and until 6:00 p.m., Mountain time, on June ____, 2003, one fully
paid and nonassessable share of Common Stock (a "Warrant Share") at the initial
exercise price (the "Warrant Price") of [$_____] payable in lawful money of the
United States of America upon surrender of this Warrant Certificate and payment
of the Warrant Price at the office of the Company designated for such purpose,
but only subject to the conditions set forth herein and in the Warrant Agreement
referred to on the reverse hereof. The Warrant Price and number of Warrant
Shares issuable upon exercise of the Warrants are subject to adjustment upon the
occurrence of certain events set forth in the Warrant Agreement.

          No Warrant may be exercised after 6:00 p.m., Mountain time, on June
__, 2003 (the "Expiration Date"). Notwithstanding the foregoing, if at 6:00
p.m., Mountain time on the Expiration Date, any Holder or Holders of the
Warrants have not exercised their Warrants and the Closing Price (as defined in
the Warrant Agreement) for the Common Stock on the Expiration Date is greater
than the Warrant Price, then each such unexercised Warrant shall be
automatically converted into a number of shares of Common Stock of the Company
equal to: (A) the number of shares of Common Stock then issuable upon exercise
of a Warrant multiplied by (B) a fraction (1) the numerator of which is the
difference between the Closing Price for the Common Stock on the Expiration Date
and the Warrant Price and (2) the denominator of which is the Closing Price for
the Warrant Stock on the Expiration Date.

          Reference is hereby made to the further provisions of this Warrant
Certificate set forth on the reverse hereof and such further provisions shall
for all purposes have the same effect as though fully set forth at this place.

          This Warrant Certificate shall not be valid unless countersigned by
the Company.

                                   [REVERSE]

     The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants expiring June __, 2003 entitling the holder on
exercise to receive shares of Common Stock, no par value per share, of the
Company (the "Common Stock"), and are issued or to be issued pursuant to a
Warrant Agreement, dated as of June __, 1998 (the "Warrant Agreement"), duly
executed and delivered by the Company, which Warrant Agreement is hereby
incorporated by reference in and made a part of this instrument and is hereby
referred to for a description of the rights, limitation of rights, obligations,
duties and immunities thereunder of the Company and the holders (the words
"holders" or "holder" meaning the registered holders or registered holder) of
the Warrants. A copy of the Warrant Agreement may be obtained by the holder
hereof upon written request to the Company.

     The Warrants may be exercised at any time on or before June __, 2003.
The holder of Warrants evidenced by this Warrant Certificate may exercise them
by surrendering this Warrant Certificate, with the form of election to purchase
set forth hereon properly completed and executed, together with payment of the
Warrant Price in cash at the office of the Company designated for such purpose.
In the event that upon any exercise of Warrants evidenced hereby the number of
Warrants exercised shall be less than the total number of Warrants evidenced
hereby, there shall be issued to the holder hereof or his assignee a new Warrant
Certificate evidencing the number of Warrants not exercised. No adjustment shall
be made for any dividends on any Common Stock issuable upon exercise of this
Warrant.

     The Warrant Agreement provides that upon the occurrence of certain events
the number of shares of Common Stock issuable upon the exercise of each Warrant
shall be adjusted. If the number of shares of Common Stock issuable upon such
exercise is adjusted, the Warrant Agreement provides that the Warrant Price set
forth on the face hereof may, subject to certain conditions, be adjusted. No
fractions of a share of Common Stock will be issued upon the exercise of any
Warrants but the Company will pay the cash value thereof determined as provided
in the Warrant Agreement.

     The holders of the Warrants are entitled to certain registration rights
with respect to the Common Stock purchasable upon exercise thereof. Said
registration rights are set forth in full in the Warrant Agreement.

     Warrant Certificates, when surrendered at the office of the Company by the
registered holder thereof in person or by legal representative or attorney duly
authorized in writing, may be exchanged, in the manner and subject to the
limitations provided in the Warrant Agreement, but without payment of any
service charge, for another Warrant Certificate or Warrant Certificates of like
tenor evidencing in the aggregate a like number of Warrants.

     Upon due presentation for registration of transfer of this Warrant
certificate at the office of the Company, a new Warrant certificate or Warrant
certificates of like tenor and evidencing in the aggregate a like number of
Warrants shall be issued to other transferee(s) in exchange for this Warrant
Certificate, subject to the limitations provided in the Warrant Agreement,
without charge except for any tax or other governmental charge imposed in
connection therewith.

     The Company may deem and treat the registered holder(s) thereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, of any distribution to the holder(s) hereof and for all other
purposes, and the Company shall not be affected by any notice to the contrary.
Neither the Warrants nor this Warrant Certificate entitles any holder hereof to
any rights of a stockholder of the Company.

                   COMMUNICATIONS SYSTEMS INTERNATIONAL, INC.
                             1998 STOCK OPTION PLAN

     On September 14, 1995, the stockholders of Communications Systems

Incentive Stock Options or had been granted pursuant to the exercise of
Incentive Stock Options under the 1995 Incentive Stock Option Plan.  Incentive
Stock Options granted prior to January 16, 1998 shall be governed by the 1995
Incentive Stock Option Plan.
     On September 14, 1995, the stockholders of the Corporation approved the
Corporation's 1995 Non-Qualified Stock Option Plan (the "1995 Non-Qualified
Stock Option Plan").  The effective date of the 1995 Non-Qualified Stock Option
Plan was August 7, 1995.  The maximum number of shares authorized to be granted
pursuant to Non-Qualified Stock Options (as defined below) under the 1995 Non-

shares were subject to outstanding Non-Qualified Stock Options or had been
granted pursuant to the exercise of Non-Qualified Stock Options under the 1995
Non-Qualified Stock Option Plan.  Non-Qualified Stock Options granted prior to
January 16, 1998, except those Non-Qualified Stock Options conditionally
granted, shall be governed by the 1995 Non-Qualified Stock Option Plan.
     On January 22, 1998, the stockholders of the Corporation approved a
proposal to combine the 1995 Incentive Stock Option Plan and the 1995 Non-
Qualified Stock Option Plan.  The effective date of this combined plan (the
"1998 Stock Option Plan" or the "Plan") is January 16, 1998.  On January 22,
1998, the stockholders also approved a proposal to increase the aggregate number
of authorized shares for Options (as defined below) to be granted under the Plan
to 3,000,000.  The total number of shares that may be issued pursuant to Options
under the Plan is 2,512,100.  The Board conditionally approved the granting of
Non-Qualified Stock Options representing 528,400 shares upon the stockholders
approval of the proposal to combine the Original Plans and approval of the
proposal to increase the number of authorized shares under the Plan.  These
conditionally granted Non-Qualified Stock Options shall be governed by this

<PAGE>

but unissued shares, shares issued and reacquired by the Corporation or shares
purchased on the market for the purposes of the Plan.  If an Option shall expire
or terminate for any reason without having been exercised in full, the
unpurchased shares, shall (unless the Plan shall have been terminated) become

     4.)  Administration.  The Plan shall be administered by the Board provided
          --------------                                                       
that the Board may appoint, from time to time, the Committee.  If a Committee
should be appointed, the Committee shall report all action taken by it to the
Board and the Committee shall have full and final authority in its discretion,
subject to the provisions of the Plan.

     The Corporation shall grant Options pursuant to the Plan upon
determinations of the Committee as to which of the eligible persons shall be
granted Options, the number of shares to be Optioned, the exercise price of the
Option and the term during which any such Options may be exercised.  The
Committee may from time to time adopt rules and regulations for carrying out the
Plan and interpretations and constructions of any provision of the Plan.  All
such determinations and  interpretations by the Committee shall be conclusively
binding for all purposes and upon all persons.

     5.)  Eligibility for Incentive Stock Options.  All employees of the
          ---------------------------------------                       
Corporation are eligible to receive Incentive Stock Options.  Incentive Stock
Options shall be granted in connection with the Optionee's employment with the
Corporation.  A director of the Corporation who is not also an employee and a
consultant to the Corporation who is not also an employee, shall not be eligible
to receive an Incentive Stock Option.

     In selecting the employees to whom Options shall be granted, as well as
determining the number of shares subject to each Option, the Committee shall
take into consideration such factors as it deems relevant in connection with
accomplishing the purposes of the Plan.  For any calendar year, the aggregate
Fair Market Value (determined at the Option Date) of the stock with respect to
which any Incentive Stock Options are exercisable for the first time by any
individual employee (under all stock option plans of the Corporation) shall not
exceed $100,000.  An employee who has been granted an Option may, if he or she
is otherwise eligible, be granted an additional Option or Options if the
Committee shall so determine.

     6.)  Eligibility for Non-Qualified Stock Options.  Non-Qualified Stock
          -------------------------------------------                      
Options may be granted to any employee, director, advisor or consultant of the
Corporation, provided however that bona fide services shall be rendered by such
advisor or consultant and such services must not be in connection with the offer
or sale of securities in a capital-raising transaction.  No further restrictions
are placed on the Committee in determining eligibility for granting Non-
Qualified Stock Options.

     7.)  Terms and Conditions of Options.  Whenever the Committee shall
          -------------------------------                               
designate an Optionee, it shall communicate to the Secretary of the Corporation
the name of the Optionee, the number of shares to be subject to the Option, the
nature of the Option (Incentive Stock Option or

                                       4
<PAGE>
 
Non-Qualified Stock Option) and such other terms and conditions as it shall
determine, not inconsistent with the provisions of this Plan.  The President or
other officer of the Corporation shall then enter into an Option Agreement with
the Optionee, complying with and subject to the following terms and conditions
and setting forth such other terms and conditions of the Option as determined by
the Committee:

     (01) The Option Agreement shall state whether it is an Incentive Stock
     Option or a Non-Qualified Stock Option.

     (02)  Number of Shares and Option Price.  The Option Agreement shall state
           ---------------------------------                                   
     the total number of shares to which it pertains.  The price of the Option
     Stock subject to an Incentive Stock Option shall be not less than one
     hundred percent (100%) of the Fair Market Value of the Option Stock at the
     Option Date.  The price of the Option Stock subject to a Non-Qualified
     Stock Option shall be determined by the Committee and may be less than the
     Fair Market Value of the Option Stock at the Option Date but shall in no
     instance be less than the par value of the Option Stock.  In the event an
     Incentive Stock Option is granted to an employee who, at the Option Date,
     owns more than ten percent (10%) of the voting power of all classes of the
     Corporation's stock then outstanding, the price of the Option Stock covered
     by such Option shall be not less than one hundred ten percent (110%) of the
     Fair Market Value of the Option Stock at the Option Date.  The Option price
     shall be subject to adjustment as provided in Section 8 hereof.

     (03)  Time and Manner of Exercise of Option.  The vesting and time of
           -------------------------------------                          
     exercise of each Option shall be determined from time to time by the
     Committee and shall be set forth in the Option Agreement with each
     Optionee.  An Option, by its terms, shall be exercisable only by the
     Optionee during the Optionee's lifetime.

          (a)   No Option may be exercised after ten (10) years from the Option
                Date; provided that no Incentive Stock Option granted to an
                owner of more than ten percent (10%) of the voting power of all
                classes of the Corporation's stock then outstanding may be
                exercised after five (5) years from the Option Date.

     (04)  Termination of Employment, Except Death or Disability.  In the event
           -----------------------------------------------------               
     that an Optionee shall cease to be employed by the Corporation for any
     reason other than his or her death, disability or "for cause," such
     Optionee shall have the right to exercise any outstanding Options which
     were exercisable at the time of termination of employment at any time
     within three (3) months after the termination of employment or until the
     earlier expiration of the Option under this Plan or the Option Agreement.
     Any exercisable Options not exercised within the three (3) month period
     shall expire at the end of such period.  In the event that the Optionee
     shall be terminated "for cause" including but not limited to: (i) willful
     breach of any agreement entered into with the Corporation; (ii)
     misappropriation of the Corporation's property, fraud, embezzlement, other
     acts of dishonesty against the Corporation; or (iii)

                                       5
<PAGE>
 
     conviction of any felony or crime involving moral turpitude, the Option
     shall expire immediately upon the Optionee's termination of employment.

     (05)  Death or Disability of Optionee.  If the Optionee shall die or become
           -------------------------------                                      
     disabled within the definition of Section 22(e)(3) of the Code while in the
     employ of the Corporation and in either case shall not have fully exercised
     his or her Options, any Options granted pursuant to the Plan which were
     exercisable at the date of termination of employment shall be exercisable
     only within twelve (12) months following his or her death or date of
     disability or until the earlier originally stated expiration thereof.  Any
     exercisable Options not exercised within the twelve (12) month period shall
     expire at the end of such period.  In the case of death, such Options shall
     be exercised pursuant to subparagraph (07) of this Section by the Successor
     and only to the extent that such Options were exercisable at the time of
     the Optionee's death.

     (06)  Transfer of Option.  Each Option granted hereunder shall, by its
           ------------------                                              
     terms, be not transferable by the Optionee other than by will or by the
     laws of descent and distribution, and shall be, during the Optionee's
     lifetime, exercisable only by the Optionee or the Optionee's legally
     appointed personal representative in the event the Optionee has been found
     legally incompetent to handle his or her affairs.  Except as permitted by
     the preceding sentence, each Option granted under the Plan and the rights
     and privileges thereby conferred shall not be transferred, assigned or
     pledged in any way (whether by operation of law or otherwise), and shall
     not be subject to execution, attachment or similar process except with the
     express consent of the Committee.  Upon any attempt to so transfer, assign,
     pledge, or otherwise dispose of the Option, or of any right or privilege
     conferred thereby, contrary to the provisions of the Option Agreement or
     the Plan, or upon levy of any attachment or similar process upon such
     rights and privileges without the express consent of the Committee, the
     Option, and such rights and privileges, shall immediately become null and
     void.

     (07)  Manner of Exercise of Options.  An Option shall be exercisable only
           -----------------------------                                      
     by: (i) written notice to the Corporation of intent to exercise the Option
     with respect to a specified number of shares of Option Stock; (ii)
     tendering the original Option Agreement to the Corporation; and (iii)
     payment to the Corporation of the amount of the Option purchase price for
     the number of shares of stock with respect to which the Option is then
     exercised.  Payment of the Option purchase price may be made in cash, by
     certified bank check, by delivery of shares of Common Stock with a Fair
     Market Value equal to the Option purchase price, by a combination of cash,
     certified bank check and such shares, whose value together with such cash
     and certified bank check shall equal the Option purchase price or by any
     other method of payment which the Committee shall approve and, in the case
     of an Incentive Stock Option, which shall not be inconsistent with the
     provisions of Section 422 of the Code.  An Option may be exercised in whole
     or in part; provided, however, that there shall be no such exercise at any
     one time as to fewer than one hundred (100) shares or all of the remaining
     shares then purchasable by the Optionee or person exercising the Option.
     When shares of Option Stock are issued to the Optionee pursuant to the
     exercise of an Option, the fact of such issuance

                                       6
<PAGE>
 
     shall be noted on the Option Agreement by the Corporation before the Option
     Agreement is returned to the Optionee.  When all shares of Optioned stock
     covered by the Option Agreement have been issued to the Optionee, or the
     Option shall expire, the Option Agreement shall be canceled and retained by
     the Corporation.  When shares of Option Stock are issued to the Optionee
     pursuant to the exercise of an Incentive Stock Option, the Corporation may
     (but shall not be required to) notify the Optionee of the period the
     Optionee must hold the shares to obtain the preferred tax treatment of the
     Incentive Stock Option.

     (08) Delivery of Certificate.  Except where shares are held for unpaid
          -----------------------                                          
     withholding taxes, between fifteen (15) and thirty (30) days after receipt
     of the written notice and payment specified above, the Corporation shall
     deliver to the Optionee certificates for the number of shares with respect
     to which the Option has been exercised, issued in the Optionee's name;
     provided, however, that such delivery shall be deemed effected for all
     purposes when the Corporation, or the stock transfer agent for the
     Corporation, shall have deposited such certificates in the United States
     mail, postage prepaid, addressed to the Optionee at the address specified
     in the written notice of exercise.

     (09) Certain Dispositions of Option Stock.  Any Incentive Stock Options
          ------------------------------------                              
     granted pursuant to this Plan shall be conditioned such that if an Optionee
     or Successor shall dispose of Option Stock by way of sale, exchange, gift,
     transfer of legal title, or otherwise within (i) the two-year period
     beginning on the Option Date, or (ii) the one-year period beginning on the
     date on which the Option Stock was transferred to such individual pursuant
     to the exercise of an Incentive Stock Option, such individual shall
     promptly report the disposition to the Corporation in writing and shall
     furnish to the Corporation such details concerning the disposition as the
     Corporation may reasonably request.

     (10) Other Provisions.  The Option Agreements under this Section shall
          ----------------                                                 
     contain such other provisions as the Committee shall deem advisable.

     8.)  Adjustments.  In the event that the outstanding shares of the Common
          -----------                                                         
Stock are changed into or exchanged for a different number or kind of shares or
other securities of the Corporation or of another corporation by reason of any
reorganization, merger, consolidation, recapitalization, reclassification, stock
split-up, combination of shares or dividends payable in Common Stock,
appropriate adjustment shall be made in the number and kind of shares as to
which Options may be granted under the Plan and as to which outstanding Options
or portions thereof then unexercised shall be exercisable, to the end that the
proportionate interest of the participant shall be maintained as before the
occurrence of such event; such adjustment in outstanding Options shall be made
by the Committee without change in the total price applicable to the unexercised
portion of such Options and with a corresponding adjustment in the Option Price
per share.  The Committee's determination shall be conclusive.  No such
adjustment shall be made which shall, within the meaning of any applicable
sections of the Code, constitute a modification, extension or renewal of an
Option or a grant of additional benefits to a participant.

                                       7
<PAGE>
 
     If the Corporation does not exercise its right under Section 13 hereof to
accelerate the date of any Options and is a party to a merger, consolidation,
reorganization or similar corporate transaction and if, as a result of that
transaction, its shares of Common Stock are exchanged for: (i) other securities
of the Corporation or (ii) securities of another corporation which has assumed
the outstanding Options under the Plan or has substituted for such Options its
own options, then each Optionee shall be entitled (subject to the conditions
stated herein or in such substituted options, if any), in respect of that
Optionee's Options, to purchase that amount of such other securities of the
Corporation or of such other corporation as is sufficient to ensure that the
value of the Optionee's Options immediately before the corporate transaction is
equivalent to the value of such options immediately after the transaction,
taking into account the Option Price of the Option before such transaction, the
Fair Market Value per share of the Common Stock immediately before such
transaction and the Fair Market Value immediately after the transaction of the
securities then subject to that Option (or to the option substituted for that
Option, if any).  Upon the happening of any such corporate transaction, the
class and aggregate number of shares subject to the Plan which have been
heretofore or may be hereafter granted under the Plan shall be appropriately
adjusted to reflect the events specified in this clause.

     9.)  Rights as Stockholder.  Neither an Optionee nor a Successor shall, by
          ---------------------                                                
reason of any Option granted hereunder, have any right of a stockholder of the
Corporation with respect to the shares covered by his or her Option until such
shares shall have been issued to the Optionee or the Successor.

     10.) No Obligation to Exercise Option.  The granting of an Option
          --------------------------------                            
shall impose no obligation upon the Optionee to exercise such Option.  Neither
shall the Plan confer upon the Optionee any rights respecting continued
employment nor limit the Optionee's rights or the Corporation's rights to
terminate such employment.

     11.) Withholding Taxes.  Whenever under the Plan shares of Option Stock
          -----------------                                           
are to be issued upon exercise of the Options granted hereunder and prior to the
delivery of any certificate or certificates for said shares by the Corporation,
the Corporation shall have the right to require the Optionee to remit to the
Corporation an amount sufficient to satisfy any federal and state withholding or
other employment taxes resulting from such exercise. In the event that
withholding taxes are not paid within five days after the date of exercise, to
the extent permitted by law the Corporation shall have the right, but not the
obligation, to cause such withholding taxes to be satisfied by reducing the
number of shares of Option Stock deliverable or by offsetting such withholding
taxes against amounts otherwise due from the Corporation to the Optionee. If
withholding taxes are paid by reduction of the number of shares deliverable to
the Optionee, such shares shall be valued at the Fair Market Value as of the
fifth business day following the date of exercise.

     12.) Purchase for Investment; Rights of Holder on Subsequent
          -------------------------------------------------------
Registration.  Unless the shares to be issued upon exercise of an Option granted
- ------------                                                                    
under the Plan have been effectively registered under the Securities Act of 1933
as now in force or hereafter amended (the "1933 Act"), the Corporation shall be
under no obligation to issue any shares covered by any Option unless the

                                       8
<PAGE>
 
person who exercises such Option, whether such exercise is in whole or in part,
shall give a written representation and undertaking to the Corporation which is
satisfactory in form and scope to counsel for the Corporation and upon which, in
the opinion of such counsel, the Corporation may reasonably rely, that he or she
is acquiring the shares issued to him or her pursuant to such exercise of the
Option for his or her own account as an investment and not with a view to, or
for sale in connection with, the distribution of any such shares, and that he or
she will make no transfer of the same except in compliance with any rules and
regulations in force at the time of such transfer under the 1933 Act, or any
other applicable law.  Such shares may be disposed of by an Optionee in the
following manner only:  (1) pursuant to an effective registration statement
covering such resale or reoffer, (2) pursuant to an applicable exemption from
registration as indicated in a written opinion of counsel acceptable to the
Company, or (3) in a transaction that meets all the requirements of Rule 144 of
the Securities and Exchange Commission.  If shares of stock covered by the Plan
have been registered with the Securities and Exchange Commission, no such
restrictions on resale shall apply, except in the case of Optionees who are
directors, officers, or principal shareholders of the Company.  Such persons may
dispose of shares only by one of the three aforesaid methods.  In the event that
the Corporation shall, nevertheless, deem it necessary or desirable to register
under the 1933 Act or other applicable statutes any shares with respect to which
an Option shall have been exercised, or to qualify any such shares for exemption
from the 1933 Act or other applicable statutes, then the Corporation shall take
such action at its own expense and may require from each participant such
information in writing for use in any registration statement, prospectus,

reserves the right to increase from time to time the rates for the Services
provided under this Agreement, regardless of any provisions in this Agreement

charges imposed on AT&T stemming from an order, rule or regulation of the

rights pursuant to this Section shall not trigger any right by Customer to
renegotiate or terminate the Agreement.

credits, or bonuses that are not expressly provided for in this Agreement.

    2.3.8. INTERNATIONAL BILLING. AT&T will calculate the length of each Carrier

seconds. The total minutes (including any fractional portion) per country will
be multiplied by that country's rate per minute. AT&T will calculate the length
of each Carrier Service International Outbound call to Mexico based upon one (1)
minute timing. The country sub-totals will be added to determine the Customer's
total usage for purposes of calculation of the Customer's attainment levels. The
Customer's total usage will be compared to the volume discount thresholds. Any
applicable volume discounts will be applied in the same month in which the
minutes occurred.

impacted by such constraints, AT&T will provide Customer with a good-faith
estimate of the availability date for such services.

4.2. INSTALLATION. Upon execution of this Agreement AT&T shall establish a due
     ------------
date for commencement of installation of Service and confirm said date with the
Customer (CISD). Customer may delay said due date for commencement of
installation when the Customer's written request for said delay is received by
AT&T at least five (5) business days prior to said due date, provided that the
delay  of said due date shall not exceed 30 cumulative calendar days. AT&T will
make every reasonable effort to commence installation of Service by the due
date,  but Customer acknowledges that in some cases a delay in commencement of
installation may be unavoidable. If commencement of installation is delayed for
more than 30 days beyond the due date, and such delay is not requested or caused
in whole or in part by the Customer, the Customer may cancel its order for
Service pursuant to this Agreement and shall not thereby be considered to have
breached this Agreement; such cancellation shall be Customer's sole remedy for
such delay.

4.3. MAINTENANCE. AT&T will maintain Service in conformity with its standard
     -----------
network operating procedures.

4.4. LIMITATION OF LIABILITY. AT&T (including its subsidiaries, affiliates,
     -----------------------
predecessors, successors and assigns) makes no warranties, express or implied,
and specifically disclaims any warranty of merchantability or fitness for a
particular purpose with respect to services or products provided pursuant to
this agreement. AT&T's liability for service interruptions for any service
provided pursuant to this agreement shall not exceed an

amount equal to a pro-rated portion of the recurring charges provided for under
this agreement for the service affected for the period(s) during which said
service was affected. This limitation of liability shall apply regardless of the
form of action, whether in contract, tort, warranty, strict liability, or
negligence (including without limitation active and passive negligence). In no
event shall AT&T be liable for consequential, special or indirect damages or
lost profits sustained by reason of its performance or non-performance of this
Agreement, or for any failure, breakdown, or interruption of service, whatever
shall be the cause, or however long it shall last, and regardless of whether
anyone has been advised of the possibility of such damages. AT&T shall have no
liability for damages caused (1) by Customer's failure to perform its
responsibilities under this agreement, or (2) by the acts of third parties
(including without limitation Customer's users or end users). AT&T does not
guarantee or make any warranty with respect to the service provided pursuant to
this agreement when used in an explosive atmosphere. This agreement does not
create any claim or right of action, nor is it intended to confer any benefit on
any third party, including but not limited to any user or end-user of Customer.
The limitations of liability set forth in this agreement shall survive failure
of an exclusive remedy.

4.5. SERVICE, CHANNELS OR EQUIPMENT OF OTHERS. AT&T is not liable for damages
     ----------------------------------------
associated with service, channels, or equipment that it does not furnish. AT&T
does not provide Customer equipment.

     ----------------------------
copyrights (other than a limited license to use) is granted by AT&T or shall be
implied or arise by estoppel, with respect to Service offered under this
Agreement.

applicable federal and state laws and regulations utilizing in part end-user
certification for verification of compliance. Customer's obligations include
payment for Service calls or services:

    - Originated at the Customer's number(s),
    - Accepted at the Customer's number(s) (e.g., Collect Calls),
    - Billed to the Customer's number(s) via Third Number Billing if the
      Customer is found to be responsible for such call or service, the use of a
      Calling Card, the use of AT&T EasyReach Service, or the use of a Company-
      assigned Special Billing Number, and
    - Incurred at the specific request of the Customer.

5.2. BILLING; PAYMENT DUE DATES; RESTRICTION OR DISCONNECTION OF SERVICE;

consolidated at AT&T's option. Said bill or bills will be sent to one Customer
location designated by the Customer. Payment is due on the 20th calendar day
from the Customer's receipt of a given bill ("Due Date"). Customer shall pay
each such bill on or before the due date by wire transfer in accordance with
AT&T's instructions. If full payment by wire transfer is not received by AT&T
on the Due Date, AT&T will notify Customer that such Service will be
disconnected unless payment is received by the 5th calendar day following the
Due Date ("Disconnect Date"). If payment is not received by the Disconnect Date
and AT&T disconnects customer for non-payment, AT&T will again notify Customer
on the day after the Disconnect Date that the disconnect order was issued.

associated with collecting delinquent payments from Customer. At AT&T's option,
interest charges may be added to any past due amounts at the rate of one and

maximum allowed by applicable law, in which case interest shall be at the
maximum lawful rate.

practicable, based on its internal business procedures. Upon agreement between
the parties, AT&T shall attempt to provide Customer within 48 hours with a call
detail in a paper form, for the given month, if requested by the Customer and
only if the Customer experiences an emergency requiring such call detail in a
paper form.

be made by Customer every Wednesday morning based on such Interim Statement.
Monthly bills will continue to be rendered pursuant to Section 5.2.

          5.2.2.1  SUSPENSION OF SERVICE. If full payment for actual usage plus
Commitment Shortfall, if any, is not received by AT&T by Wednesday noon in any
given week, AT&T shall have the right to suspend Service hereunder that day upon
oral or faxed notice to Customer. AT&T shall restore service promptly upon
receipt of such past due amounts, subject to its rights under Section 5.2 above.

    5.2.3. MEANS OF PAYMENT. Payment shall be effected by wire transfer to
AT&T's account at Mellon Bank, 3 Mellon Bank Center, Room 153-2614, Pittsburgh,

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

Agreement, including but not limited to the responsibility to render to AT&T
timely payment of charges.

5.4.  INTERFACING AND COMMUNICATING WITH END-USERS. Interfacing and
      --------------------------------------------

BETWEEN AT&T AND CS INTL                            RESPONSIBILITIES OF CUSTOMER
- --------------------------------------------------------------------------------

5.5.  DEPOSITS. AT&T may require the Customer, prior to or during the provision
      --------
of Service pursuant to this Agreement, to tender a deposit in an amount to be
determined by AT&T in its reasonable discretion to be held by AT&T as a
guarantee for the payment of charges. To determine the financial responsibility
of Customer and/or the specific amount of any deposit required, AT&T may rely
upon commercially reasonable factors to assess and manage the risk of
non-payment, including but not limited to payment history for telecommunications
service (including such service purchased from AT&T), number of years in
business, bankruptcy or insolvency history, current AT&T account treatment
status, financial statement analysis, and commercial credit bureau rating. It
shall be Customer's responsibility to provide to AT&T upon request such
information as is necessary for AT&T to determine the financial responsibility
of Customer, including but not limited to Customer's tax returns, audited or
unaudited financial statements and loan applications. A deposit does not relieve
Customer of the responsibility for the prompt payment of bills on presentation
or the due date appearing on the face of the bills. In lieu of a cash deposit,
AT&T will accept Bank Letters of Credit and Surety Bonds which have been
approved by AT&T. Interest will be paid to Customer for the period that a cash
deposit is held by AT&T. The interest rate used will be compound interest
compounded monthly at the rate of six percent annually unless a different rate
has been established by the appropriate legal authority in the state where the
Service offering is located. The failure of Customer to post a deposit as
required by AT&T pursuant to this paragraph shall constitute a material breach
of this Agreement by Customer which shall entitle AT&T to terminate this
Agreement and the Service provided hereunder upon five (5) business days written
notice to Customer. When the Service for which the deposit has been required is
discontinued, the deposit will be applied to the final bill and any credit
balance will be refunded to the Customer with applicable interest accrued.

5.6.  CUSTOMER'S USE OF SERVICE. Customer may use the Services provided pursuant
      -------------------------
to this Agreement for any lawful purpose consistent with the transmission and
switching parameters of the telecommunications network, and may resell its use
(or the use of any part thereof) to a third party in the normal course of the
Customer's business, subject to the following:

5.6.1.   ABUSE. The abuse of Service is prohibited. The following activities 
         -----
constitute abuse:

         5.6.1.1.  Using Service to make calls that might reasonably be
         expected to frighten, abuse, torment, or harass another, or

         5.6.1.2. Using Service in such a way that it interferes unreasonably
         with the use of Service or AT&T's network by others.

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

       In any instance in which AT&T believes in good faith that there is abuse
       of Service as set forth above, AT&T may, upon 5 days prior written notice
       to the Customer, and without liability on the part of AT&T, restrict,
       suspend or discontinue providing Service, unless Customer cures such
       abuse to AT&T's reasonable satisfaction within such period.

5.6.2. FRAUDULENT USE. The fraudulent use of, or the intended or
       --------------
attempted fraudulent use of, Service is prohibited. The following
activities constitute fraudulent use:

       5.6.2.1. Using Service to transmit any message or code, locate a person,
       or otherwise give or obtain information, without payment for Service, or

       5.6.2.2. Using or attempting to use Service with the intent to avoid the
       payment, either in whole or in part, of any charges by any means or
       device, or

       5.6.2.3. Using Service to carry calls that originate on the network of a
       facilities-based interexchange carrier other than AT&T and terminate
       disproportionately to locations for which the cost to AT&T of terminating
       switched access is above the average cost of terminating switched access,
       based on the published access tariffs of local exchange companies.

       In any instance in which AT&T believes in good faith that there is
       fraudulent use of Service as set forth above, AT&T may, immediately and
       upon written notice to the Customer, and without liability on the part of
       AT&T, restrict, suspend or discontinue providing Service.

    5.6.3. INTERFERENCE, IMPAIRMENT OR IMPROPER USE. Customer may not use
Service in any manner that subjects AT&T personnel or non-AT&T personnel to
hazardous conditions or results in immediate harm to the AT&T network or other
AT&T services. In any instance in which AT&T believes in good faith that Service
is being used in such manner, AT&T may immediately restrict Service on a
temporary basis. In such cases, AT&T will make a reasonable effort to give the
Customer prior notice. In the event that Customer does not provide to AT&T
within five (5) business days of the temporary restriction of Service acceptable
proof that said use has ceased and that appropriate measures have been taken to
prevent its recurrence, AT&T may immediately and without further notice
terminate Service.

5.7.  ACCESS TO CUSTOMER'S PREMISES. The Customer is responsible for arranging
      -----------------------------
premises access at any reasonable time so that AT&T personnel may install,
repair,

      ----------------------------
harmless AT&T and its directors, officers, employees, agents, parent,
subsidiaries, successors, and assigns from all claims, damages and expenses
(including reasonable attorneys' fees) arising out of or resulting from, in

Customer's Users or End-users arising out of any failure, breakdown, or
interruption of service provided to Customer by AT&T or to End-users by

withheld. AT&T may, in its discretion, condition its consent to such
assignment upon the posting of an appropriate deposit by the assignee pursuant
to Paragraph 5.5. of this Agreement. AT&T reserves the right to deny or revoke
its consent to such assignment at any time if the assignee proves unwilling or
unable to comply with the representations and warranties set forth in Section 3
of this Agreement, in which event the Customer shall remain or again become
responsible for performance of all terms of this Agreement. This provision shall
not affect the Customer's right to resell Service. Further, any resale or

                                   RECITALS
                                   --------

     A.   Landlord is the owner of the One Wilshire Building, located at 624 S. 
Grand Avenue, Los Angeles, California 90017 (the "Building"). Landlord leases to
Tenant Suite 2840 in the Building (the"Premises") pursuant to a written lease 
dated June 10, 1996, as amended to date (the "Lease").

     B.   Landlord has set aside a portion of the fourth floor of the Building 
for use as a special conduit room (the "Conduit Room") and has set aside a 
portion of the Building's parking elevator shaft for use as a special conduit 
shaft (the "Conduit Shaft"). The purpose of the Conduit Room and the Conduit 
Shaft will be to facilitate interconnections between various telecommunications 
company tenants in the Building who elect to participate.

     C.   Tenant wishes to obtain a license from Landlord for use of the Conduit
Room, in common with others, and use of certain conduit space (the "Connecting 
Conduit") running from the Premises through the Conduit Shaft to the Conduit 
Room. Landlord is willing to give Tenant a non-exclusive license, revocable by 
Landlord at will under the circumstances described in Section 5 below, for use 
of the Conduit Room and the Connecting Conduit on the terms and conditions set 
forth below.

     NOW THEREFORE, the parties hereby agree as follows:

                                       1
<PAGE>
 
                                   AGREEMENT
                                   ---------

     1.   License for Use of Conduit. Landlord hereby grants to Tenant a 
          --------------------------
non-exclusive license, revocable by Landlord at will under the circumstances 
described in Section 5 below, for use of the Conduit Room and the Connecting 
Conduit. Such use shall be on the terms and conditions set forth in this 
Amendment. Tenant shall have the right to commence such use on or after the date
Landlord first makes the Conduit Room available for use by Landlord's licensees
following Landlord's construction of the Conduit Room and installation of the
Connecting Conduit (the "Effective Date"). If for any reason the Conduit Room
has not been constructed or the Connecting Conduit has not been installed by
the estimated Effective Date of August 1, 1997, Landlord shall have no liability
to Tenant for such delay. However, in such event, Tenant, as Tenant's sole and
exclusive remedy, shall have no obligation for the monthly license fee described
in Section 2 until the Conduit Room has been constructed, the Connecting Conduit
has been installed, and the Effective Date has occurred.

     In connection with Tenant's use of the Conduit Room, Tenant shall be 
provided with use of the following items ("Landlord Installations") in the 
Conduit Room in the quantities indicated:

     ______ 22-inch relay racks

        1   2' by 2' lockable cabinets
     ------       

     ______ 4' by 6' lockable cages

     The Connecting Conduit shall run from the Premises and through the Conduit 
Shaft to one of Tenant's racks, cages or cabinets in the Conduit Room, as 
designated by Tenant. Landlord, in its reasonable discretion, shall designate 
which conduit in the Conduit Shaft shall be used for the Connecting Conduit. The
Connecting Conduit shall consist of conduit in the following quantities and 
sizes:

        1    1-inch conduits
     ------

     ______  4-inch conduits
     
     Tenant acknowledges that other tenants and licensees in the Building will
also be using similar Landlord Installations in the Conduit Room. Tenant agrees
to use the Conduit Room only for the purpose of facilitating interconnections
between Tenant's telecommunications system and the telecommunications systems of
other tenants and licensees who reserve Landlord Installations in the Conduit
Room and who consent in writing to such an interconnection. Tenant agrees not to
store, install or use any equipment, conduit, cable, connecting lines or other
property of Tenant in the Conduit Room for any other purpose. Tenant shall
cooperate in keeping the Conduit Room locked and in restricting access to the
Conduit Room to employees, contractors and other persons who need access in
order to facilitate such interconnections. In no event shall Tenant cause (or
permit its employees, representatives, contractors or invitees to cause) any
interference with or damage to the Landlord Installations, equipment, conduits,
cable, wiring or connecting lines owned or used by other tenants in the Conduit
Room. Landlord shall equip the Conduit Room with security cameras and a 24-hour
security access system. Landlord shall also provide all tenants and licenses of
Landlord who use the Conduit Room with standard specifications for all wiring,
cabling and connecting lines to be installed in the Conduit Room by such tenants
or licensees. Landlord also shall have the right, in Landlord's reasonable
discretion, to enforce such other security measures and installation guidelines
as Landlord deems appropriate. However, Landlord shall have no liability to
Tenant for any damage or in terference caused by any person to the Landlord
Installations assigned to Tenant or to the cable, wiring, connecting lines,
equipment or other property of Tenant in the Conduit Room or the Connecting
Conduit.

     Landlord's only obligation to Tenant regarding the installation of
facilities pursuant to this Amendment shall be to install the Landlord
Installations assigned to Tenant in the Conduit Room and the Connecting Conduit.
The cost of such work, together with Landlord's related administrative fee, is
included in Tenant's installation payment to Landlord described in item
          
                                       2
<PAGE>
 
(b) in Section 2 below. Tenant's share of Landlord's cost of constructing the 
Conduit Room and the Conduit Shaft themselves is included in Tenant's one-time 
participation payment described in item (a) in Section 2.

     All installation of wiring or cabling that Tenant wishes installed in the 
Connecting Conduit shall be installed by Landlord's designated contractor at 
Tenant's expense. Tenant agrees to pay Landlord the cost of such work, together 
with Landlord's 10% administrative fee, within 10 days after receipt of a 
billing from Landlord. Landlord shall have the right, at Landlord's election, to
require Tenant to pay for the work in advance.

     All installation of wiring, cabling and connections for Tenant's use within
the Conduit Room, including but not limited to any wiring, cabling or
connections in or about the Landlord Installations, shall be performed at
Tenant's sole expense by a qualified, duly licensed contractor selected by
Tenant. Landlord shall have no obligation or liability with respect to such work
by Tenant's contractors. Tenant shall cause all such work by Tenant's
contractors to be completed and paid for promptly to prevent any mechanic's
liens being filed. Tenant shall also cause all such work by Tenant's contractors
to comply with Landlord's rules and regulations in effect from time to time for
work in the Building, as well as the requirements in Landlord's Special Conduit
Room Rules in effect from time to time. (The Special Conduit Room Rules
initially shall be as set forth in Exhibit A.) Such requirements include, but
shall not be limited to, the requirement that, prior to starting the work, the
contractor or Tenant must provide to Landlord (i) evidence of insurance coverage
for the work in conformity with the standards in Landlord's rules, (ii) copies
of all legally required permits for the work, and (iii) a copy of the written
consent of any other licensee in the Conduit Room with whose facilities a
connection will be made as part of the work. Tenant shall notify Landlord in
writing before Tenant's contractor commences any such work, so that Landlord
may, if Landlord so elects, post notices of nonresponsibility.

     Tenant's ongoing use of the Conduit Room, the Connecting Conduit and 
Tenant's cable, wiring, and connecting lines shall comply with all applicable 
laws, the other provisions of the Lease, and the Building's rules (including but
not limited to the Special Conduit Room Rules) adopted by Landlord from time to
time. Tenant's use shall not interfere in any way with the operation of the
Building or with the occupancy or activities of any other tenant.

     2.   License Fees. Tenant agrees to pay Landlord a license fee for use of 
          ------------
the Conduit Room and the Connecting Conduit, which initially shall be (a) a 
one-time participation fee of $12,000 for use of the Conduit Room, plus (b) 
installation costs in the amount of $11,100 for the Connecting Conduit and for 
the Landlord Installations assigned to Tenant in the Conduit Room (not including
Tenant's cable, wiring, or connecting lines in the Connecting Conduit and the 
Conduit Room). The additional installation amounts of section b shall be due and
payable within 30 days of the actual installation date. (No portion of such 
amounts shall be refundable if the Lease or this license is terminated for any 
reason.)

     After Tenant's initial payment, the license fee for the Conduit Room and
the Connecting Conduit shall be $500 per month, subject to adjustment as
provided below. Such license fee shall be due and payable to Landlord on the
first day of each month or portion of a calendar month throughout the balance of
the Lease term, unless and until this license is revoked by Landlord in
accordance with Section 5 below. (Any such revocation shall not affect the
balance of the Lease, except that Landlord may treat any default by Tenant
hereunder as a default under the Lease.) Such license fee shall be paid together
with Tenant's Base Rent and other monthly charges, with the first such
installment of the license fee due on the Effective Date. The monthly license
fee for any partial calendar month shall be equitably prorated, as calculated by
Landlord in its reasonable discretion. In addition to the monthly charges stated
above, Tenant shall be obligated to pay for any power usage on a monthly basis
if Tenant requires equipment to be hooked up to a power source.

     The amount of the monthly license fee shall be adjusted as of each January
1 during the Lease term. For purposes of calculating such adjustment, the
Consumer Price Index for All Urban Consumers, U.S. City Average, All Items
(1967=100), unadjusted (herein the "Index") published by the Bureau of Labor
Statistics of the United States Department of Labor for the month during which
the Effective Date occurs shall be the base Index figure (the "Base Index"). The
Base Index shall be compared to the Index figure for December of each year
during the term of the Lease, including the initial partial calendar year during
which the Effective Date occurs. In the event that the Index figure for December
of any year during the term of the Lease shall be greater than the Base Index,
then in addition to the monthly license fee, Tenant shall pay to Landlord a
monthly amount equal to the same percentage increase in the monthly license fee
as the percentage increase in the Index for

                                       3
<PAGE>
 
such December over the Base Index. Such amount shall be payable monthly 
commencing with the payment of the license fee for the January immediately 
following such December.

     In the event that the Index for any December during the term of the Lease 
is not yet available upon the date that any installment of the monthly license 
fee is due, Tenant shall continue paying the monthly license fee, as previously 
adjusted, in the amount applicable for such December until the Index for that 
month is published, whereupon Tenant shall immediately pay Landlord the 
adjustments which would have been due in the months following such December had 
the Index for such December been available. In the event that publication of the
Index is discontinued, Landlord and Tenant agree that the index of consumer 
prices which is most closely analogous to the Index shall be used in place of 
the Index for calculation of the adjustments payable hereunder. In the event 
that the referents or techniques employed in the calculation of the Index shall 
be modified and such modification would have resulted in a different figure for 
the Base Index, Landlord and Tenant agree that the Base Index shall be 
appropriately adjusted and that the Index, as modified, shall be used as 
provided hereunder.

     3.   INDEMNITY AND WAIVER. Tenant hereby agrees to indemnify and hold 
          --------------------
harmless Landlord and its partners, its agent Paramount Group, Inc. and their
respective officers, directors, shareholders, agents and employees
(collectively, the "Landlord Group") from and against any and all claims
(including but not limited to claims for bodily injury or property damage),
actions, mechanic's liens, losses, liabilities, and expenses (including
reasonable attorney fees and costs of defense by Landlord's legal counsel)
(collectively, "Claims"), which may arise from the installation, operation, use,
maintenance or removal of conduit, cable, wiring, connecting lines, equipment or
other property pursuant to this Amendment or from Tenant's use of the Conduit
Room, the Connecting Conduit, or the Landlord Installations. Similarly, Tenant
shall pay upon demand by Landlord the costs to repair any physical damage to the
Building caused by such installation, operation, use, maintenance or removal.
Tenant hereby waives and releases the Landlord Group from any Claims Tenant may
have at any time (including but not limited to Claims relating to interruptions
in services) arising out of or relating in any way to the installation,
operation, use, maintenance, or removal of conduit, cable, wiring, connecting
lines, equipment or other property described in this Amendment or Tenant's use
of the Conduit Room, the Connecting Conduit, or the Landlord Installations,
whether or not caused by the negligence of any member of the Landlord Group or
Landlord's contractors. Such waiver and release shall not apply to Claims to the
extent caused by Landlord's wilful misconduct. However, in no event shall
Landlord or any member of the Landlord Group be liable to Tenant for lost
profits or consequential, incidental or punitive damages of any kind.

     4.   REMOVAL OF CABLE, WIRING AND CONNECTING LINES. Tenant agrees that, 
          ---------------------------------------------
upon the termination of this license as described in Section 5 below, Tenant 
(or, at Landlord's election, the contractor designated by Landlord) shall
promptly remove, at Tenant's sole cost and expense, all cable, wiring,
connecting lines, and other installations, equipment or property installed or
placed by or for Tenant in the Conduit Room or the Connecting Conduit (excepting
the Connecting Conduit itself and the Landlord Installations, which shall remain
the property of Landlord), and restore those portions of the Building damaged by
such removal to their condition immediately prior to the installation or
placement of such items. If Tenant fails to promptly remove all such items
pursuant to this Section 4, or if Landlord elects to have such work performed by
Landlord's contractor, Landlord may remove such items and restore those portions
of the Building damaged by such removal to their condition immediately prior to
the installation or placement of such items, in which case Tenant agrees
promptly to pay Landlord's reasonable costs of removal and restoration,
including Landlord's administrative fee.

     5.   NO LEASE OR EASEMENT OF CONDUIT ROOM OR CONNECTING CONDUIT: 
          -----------------------------------------------------------
TERMINATION OF LICENSE.  Tenant acknowledges that the rights granted to Tenant 
- ----------------------
hereunder do not constitute a lease of any portion of the Conduit Room, the
Connecting Conduit or the Landlord Installations nor an easement, but rather
constitute a non-exclusive license for use in common with others. Such license
is revocable by Landlord in Landlord's sole discretion upon any default by
Tenant under the Lease which is not cured within the applicable cure period.
Landlord shall retain such rights of revocation notwithstanding any expenditure
of money on the installations described herein or other actual or alleged
reliance by Tenant. Such revocation shall be made by written notice from
Landlord to Tenant. The license shall terminate in any event, without notice
from Landlord, upon the expiration or termination of the Lease. Such license is
personal to Tenant, and Tenant's rights hereunder may not be assigned (except in
connection with a permitted assignment of Tenant's entire interest in the
Lease), sub-licensed, or otherwise transferred in any fashion, regardless of
whether such an arrangement is called an assignment, a sub-license, a co-
location agreement or any other name. Tenant agrees not to permit any third
party to place, use or operate their own equipment, wiring, cabling or
connecting lines in or about Tenant's Landlord Installations or Connecting
Conduit. Any default by Tenant under this Amendment shall be deemed to be a
default under the Lease. The license fee described in Section 2 above shall be
deemed to be additional rent for the Premises described in the Lease, and Tenant
acknowledges that the availability of the license enhances the value of those
Premises. Tenant shall remain obligated for such additional rent for the balance
of

                                       4

the Lease term, and shall remain obligated for Tenant's other obligations under
this Amendment, regardless of whether Tenant actually makes use of the license,
or whether Tenant surrenders the license, or whether the license is terminated
due to Tenant's default under the Lease.

     6.   Applicability of Other Provisions. Except as explicitly provided 
          ---------------------------------
otherwise herein, Tenant's obligations under the Lease for the protection of the
Building, Landlord, the Landlord Group, and third parties, including but not
limited to Tenant's obligations regarding maintenance, repairs, mechanic's
liens, insurance, attorneys' fees and costs of suit, shall apply in the same
fashion with respect to Tenant's use of the Conduit Room, the Connecting Conduit
and the Landlord Installations as they do with respect to Tenant's use of the
Premises.

     7.   Miscellaneous. This Amendment supersedes all prior or contemporaneous 
          -------------
understandings, negotiations, or agreements between the parties, whether written
or oral, with respect to its subject matter. The Lease, as amended herein, may
be further amended only in a writing signed by both Landlord and Tenant.

     IN WITNESS WHEREOF, the parties have executed this Amendment as of the date
and at the place first written above.

                             ONE WILSHIRE BUILDING
                             ---------------------
                       CONDUIT ("MEET POINT") ROOM RULES
                       ---------------------------------

     The Meet Point Room is a conduit room located on the fourth floor of the 
One Wilshire Building located at 624 S.  Grand Avenue, Los Angeles, California 
90017 (the "Building") for the special purpose of facilitating interconnections 
between various telecommunications providers and users who currently hold 
licenses with the Building for the use of such facilities ("Participants").  As 
a condition to maintaining their license and to the ongoing use of the Meet 
Point Room, all Participants must comply with the Meet Point Room set forth 
herein and as may be adopted or revised by the Building in its reasonable 
discretion from time to time.

     These Meet Point Room Rules are in addition to the terms, convenants, and 
conditions of any agreement (including but not limited to a lease) between 
Participant and the Building for use of the Meet Point Room.  In the event these
Rules conflict with any provision of such agreement, such agreement shall 
control.

     The Building may waive any one or more of these Meet Point Room Rules for 
the benefit of a Participant, but no such waiver by the Building shall be 
construed as a waiver of such Rules in favor of anyone other than such 
Participant for whose benefit such waiver was expressly intended, nor prevent 
the Building from thereafter enforcing such Rules against such Participant or 
any or all of the other Participants.

     The Building reserves the right to make such other and reasonable Meet 
Point Room Rules as, in its judgement, may from time to time be necessary or 
desirable.  Participant agrees to abide by all such Meet Point Room Rules as 
stated herein and any additional rules and regulations which are adopted.

1.   Participants must furnish the Building with the names (and other necessary
     identification as Building may require) of its personnel who are authorized
     by Participant to enter the Meet Point Room.  Participants are responsible
     for keeping such authorized user list current.

2.   Participants wishing to enter into the Meet Point Room must sign in at the 
     Meet Point Room log book located at the Building Security Desk.

3.   Each person wishing to enter the Meet Point Room must be on the authorized
     user list.  Positive proof of identity is required before entrance to the
     Meet Point Room is permitted.  A driver's license or other authenticated
     photograph identification is the only acceptable form of positive proof.
     Such form of identification will be held as security until Participant
     completes Participant's activities in the Meet Point Room.

4.   Each person wishing to enter the Meet Point Room must obtain a security
     access card from Building Security each time he or she wishes to enter. On
     entering or leaving the Meet Point Room, Participant must make sure the
     door is shut and not left ajar.

5.   If Participant intends to perform cross-connect work in the Meet Point 
     Room, upon entry Participant must submit a fully executed (by Participant 
     and the Building's authorized representative) Cross-Connect Authority Form 
     in the form provided by the Building.

6.   Upon leaving the Meet Point Room, Participant must sign out in the Meet
     Point Room log book at which time Participant's photo identification will
     be returned.

7.   All activities in the Meet Point Room must be in compliance with the law 
     including all applicable local, state, and federal laws, rules, codes and 
     regulations.

                                     CRR-1

8.   Participants desiring to interconnect to another Participant's cross-
     connect array must negotiate such interconnection directly with such other
     Participant and the Building shall have no obligations in that regard.

9.   All cross-connects must be accomplished utilizing Building-standard cable
     and wire and following approved procedures.

10.  All wiring shall be routed through the furnished channels, raceways, etc.
     All cable shall be dressed-in and secured so as to ensure a professional
     appearance, run straight and level, with 90 degree corners where possible.
     Where to wraps are used, the end shall be cut to preserve the professional
     appearance.

11.  Groups of cable routed to the Meet Point Room shall remain bundled together
     to the degree possible for easy indentification.

12.  All cables must be clearly labeled utilizing Building-provided tags.

13.  The Meet Point Room must be kept clean and free of debris at all times.

14.  Tampering in any way with other Participants' circuits and cross-connects
     is not permissible and is grounds for immediate revocation of Participant's
     Meet Point Room rights. All other infractions of Meet Point Room Rules must
     be corrected within 24 hours of notification.

15.  If circuit tampering is detected at any time by any Participant, it must be
     reported immediately to the Building Security Desk.

16.  Notification of infraction is accomplished by Building Management's
     delivery of a written warning to the Participant.

17.  Receipt of three (3) warnings within a six-month period is cause for
     immediate revocation of Meet Point Room participation rights.

18.  Meet Point Room participation rights are subject to revocation for any
     default under the agreement between the Building and Participant regarding
     Participant's use of the Meet Point Room.

19.  Upon expiration or revocation of Meet Point Room participation rights,
     Participant must make arrangements to vacate the Meet Point Room and remove
     all cross-connects associated with Participant's assigned array(s) within
     30 calender days of notification.

                                   AGREEMENT
                                   ---------

     1.   PREMISES.  Landlord hereby leases the Premises to Tenant and Tenant
hereby hires and takes the Premises from Landlord. The Premises are located at
the address set forth in Section A(1) on page 1 and are more particularly shown
on Exhibit "A" attached hereto and incorporated herein by this reference. The
office building in which the Premises are located is referred to herein as the
"Building."

     2.   TERM.

     2.1  The term of this Lease shall commence on the "Commencement Date"
indicated in Section D on Page 1 and shall extend for the period set forth in
Section C on Page 1. In the event that Landlord, for any reason, cannot tender
possession of the Premises to Tenant on or before the "Estimated Commencement
Date" indicated in Section D on Page 1, this Lease shall not be void or
voidable, nor shall Landlord be liable to Tenant in any way as a result of such
failure to tender possession. In the event that Landlord cannot tender
possession of the Premises to Tenant for any reason other than the acts or
omissions of Tenant, Tenant's obligation to pay rent hereunder shall be deferred
by a period of time equal to the delay in Landlord's delivery of possession not
caused by Tenant. If such inability to tender possession of the Premises for
reasons other than the acts or omissions of Tenant continues for a period in
excess of 90 days after the Estimated Commencement Date, Tenant shall have the
right, exercisable by notice to Landlord, to terminate this Lease, but the
suspension of rent obligations and the right of termination pursuant to this
Section 2.1 shall be Tenant's sole remedies in the circumstances herein
described.

     2.2  In the event that Tenant is allowed to enter into possession of the
Premises prior to the Commencement Date, such possession shall be deemed to be
pursuant to, and shall be governed by, the terms, covenants and conditions of
this Lease, including without limitation the covenant to pay rent, as though the
Commencement Date occurred upon the date of taking of possession by Tenant.

     2.3  In the event that the Commencement Date falls on other than the first
day of a month, rent for any initial partial month of the term hereof shall be
appropriately prorated; and if the date of commencement of Tenant's rent
obligations is delayed, pursuant to Section 2.1, the end of the term hereof
shall be correspondingly delayed. At the request of either party hereto, both
parties shall execute a memorandum confirming the date of commencement of
Tenant's rent obligations.

     3.   RENT.  Beginning on the Commencement Date (subject to adjustment
pursuant to Section 2.1 above), the base rent ("Base Rent") for the Premises
shall be in accordance with the Schedule of Monthly Base Rents set forth in
Section E on Page 2. Each installment of Base Rent shall be payable in advance
on the first day of each and every month throughout the term of this Lease.
Tenant agrees to pay all rent, without offset, demand or deduction of any kind,
to Landlord by mail to the address set forth in Section A(3) on page 1 or in
such manner, to such other person or at such other place as Landlord may from
time to time designate. Tenant agrees that no payment made to Landlord by check
or other instrument shall contain a restrictive endorsement of any kind; and if
any such instrument should contain a restrictive endorsement in violation of the
foregoing, that endorsement shall have no legal effect whatever, notwithstanding
that such item is processed for payment.

     4.   RENT ESCALATION.

     4.1  Tenant shall pay, as monthly rent hereunder, in addition to the Base
Rent, the sums provided in this Section 4. Tenant shall be advised of any
change, from time to time, in rent escalation payments required hereunder by
written notice from Landlord, which shall include information in such detail as
Landlord may reasonably determine to be necessary in support of such change.
Tenant shall have 30 days after the receipt of any such notice to protest the
change indicated therein, and Tenant's failure to make such protest in a written
notice to Landlord within such 30-day period shall be conclusively deemed to be
Tenant's agreement to such charges. Notwithstanding any such protest all rent
escalation payments falling due after service of such notice shall be made in
accordance with such notice until the protest has been resolved, whereupon any
necessary adjustment shall be made between Landlord and Tenant. Any audit
arising out of such a protest by Tenant shall be done, at Tenant's expense, in
accordance with generally accepted auditing and management standards by a major
public accounting firm selected by Tenant and approved by Landlord in its
reasonable discretion. Such audit shall be performed at the offices of Paramount
Group, Inc. in New York City or at such other location in the United States as
Landlord may select from time to time for the maintenance of its accounting
records for the Building.

     4.2  Following the first December 31 during the term of the Lease, Tenant
shall pay Landlord in a single lump sum upon billing therefor, Tenant's
Percentage Share (as defined in Section G on Page 2 of the Lease) of each of the
following amounts: (1) the amount (if any) by which Real Estate Taxes for the
then current tax fiscal year exceed the Real

                                       3
<PAGE>
 
Estate Taxes for the Base Year for Real Estate Taxes set forth in Section F on 
Page 2; (2) the amount (if any) by which Operating Costs for the just completed 
calendar year exceed the Operating Costs for the Base Year for Operating Costs 
set forth in Section F on Page 2; and (3) the amount (if any) by which Utility 
Costs for the just completed calendar year exceed the Utility Costs for the Base
Year for Utility Costs set forth in Section F on Page 2. At the same time Tenant
shall also pay to Landlord one-twelfth of Tenant's Percentage Share of such 
amounts for each month that has commenced since December 31 as estimated 
payments towards Tenant's share of the Real Estate Taxes, Operating Costs, and 
Utility Costs for the following year. Following each succeeding December 31, 
Landlord again shall determine in the same fashion the increase or decrease (if 
any) in annual Real Estate Taxes, Operating Costs, and Utility Costs over or 
under those for the previous year. If there is an increase in one or more of the
three categories, Tenant shall pay to Landlord in a single lump sum upon billing
Tenant's Percentage Share of the increase plus one-twelfth of Tenant's 
Percentage Share of such increase for each month that has then commenced in the 
new calendar year. If there is a decrease in one or more of the three 
categories, Landlord shall refund to Tenant or, at Landlord's option, credit 
against the next rent falling due under the Lease the amount of the overpayment 
made by Tenant during the preceding calendar year, provided that the amount of 
such refund or credit shall in no event exceed the total payments previously 
made by Tenant for such calendar year toward Tenant's Percentage Share of excess
charges for the category in question. Thereafter, with each month's Base Rent 
until the next adjustment hereunder, Tenant shall pay one-twelfth of Tenant's 
Percentage Share of each of the following amounts: (I) the excess (if any) of
annual Real Estate Taxes (based on the then-current fiscal year) over the Base
Year Real Estate Taxes; (II) the excess (if any) of annual Operating Costs
(based on the preceding calendar year) over the Base Year Operating Costs; and
(III) the excess (if any) of annual Utility Costs (based on the preceding
calendar year) over Base Year Utility Costs. The Real Estate Taxes for any
partial fiscal year at the end of the Lease term and the Operating Costs and
Utility Costs for any partial calendar year at the end of the Lease term shall
be appropriately prorated.

     For purposes hereof, "Real Estate Taxes" shall include any form of 
assessment, license fee, license tax, business license fee, commercial rental 
tax, levy, penalty, charge, tax or similar imposition (other than net income, 
inheritance or estate taxes) imposed by any authority having the direct or 
indirect power to tax, including any city, county, state or federal government, 
or any school, agricultural, lighting, drainage, flood control or other special 
district thereof, as against any legal or equitable interest of Landlord in the 
Premises or in the real property of which the Premises and the Building are a 
part, including, but not limited to, the following:

          (i)    Any tax on Landlord's "right" to rent or "right" to other 
income from the Premises or as against Landlord's business of leasing the 
Premises;

          (ii)   Any assessment, tax, fee, levy or charge in substitution, 
partially or totally, of any assessment, tax, fee, levy of charge previously 
included within the definition of Real Estate Taxes, it being acknowledged by 
Tenant and Landlord that Proposition 13 was adopted by the voters of the State 
of California in the June, 1978 Election and that assessments, taxes, fees, 
levies and charges may be imposed by governmental agencies for such services as 
fire protection, street, sidewalk and road maintenance, refuse removal and for 
other governmental services formerly provided without charge to property owners 
or occupants. It is the intention of Tenant and Landlord that all such new and 
increased assessments, taxes, fees, levies and charges be included within the 
definition of "Real Property Taxes" for the purpose of this Lease;

          (iii)  Any assessment, tax, fee, levy or charge allocable to or 
measured by the area of the Premises or the rent payable hereunder, including, 
without limitation, any gross income tax or excise tax levied by the State, City
or Federal government, or any political subdivision thereof, with respect to the
receipt of such rent, or upon or with respect to the possession, leasing, 
operating, management, maintenance, alteration, repair, use or occupancy by 
Tenant of the Premises, or any portion thereof;

          (iv)   Any assessment, tax, fee, levy or charge upon this transaction 
or any document to which Tenant is a party, creating or transferring an interest
or an estate in the Premises;

          (v)    Any assessment, tax, fee, levy or charge by any governmental 
agency related to any transportation plan, fund or system instituted within the 
geographic area of which the Building is a part; or

          (vi)   Reasonable legal and other professional fees, costs and 
disbursements incurred in connection with proceedings to contest, determine or 
reduce real property taxes.

     The definition of "Real Estate Taxes," including any additional tax the 
nature of which was previously included within the definition of "Real Estate 
Taxes," shall include any increases in such taxes, levies, charges or 
assessments occasioned by increases in tax rates or increases in assessed 
valuations, whether occurring by sale or otherwise.

                                       4

     As used in this Lease, the term "Operating Costs" shall mean all costs and

accounting practices, including the following costs by way of illustration but
not limitation:

          (a)  Any and all assessments imposed with respect to the Building,

improvement or repair of the Building;

          (e)  Building management office and storage rental;

          (f)  Management and administrative fees (which Tenant acknowledges

adjusted from time to time);

          (h)  Costs of, and appropriate reserves for, repair, painting,

including but not limited to the elevators, the structural portions of the

          (i)  Depreciation on a straight-line basis and rental of personal

capital repairs, capital equipment and capital tools);

               (1)  reasonably intended to produce a reduction in Operating 
Costs, Utility Costs or energy consumption; or

               (2)  required under any governmental or quassi-governmental law,

          (k)  Costs and expenses of gardening and landscaping;
 
          (l)  Maintenance of signs (other than signs of tenants of the

          (o)  Reasonable accounting, audit, verification, legal and other

     The following shall be excluded from Operating Costs: federal and state

procure tenants for the Building, including but not limited to brokerage
commissions, legal fees,and costs of remodeling suites; mortgage or debt

     For purposes hereof, "Utility Costs": shall include all charges, surcharges
and other costs of all utilities paid for by Landlord in connection with the
Premises and/or Building, cost of furnishing gas, electricity and other fuels or
power sources to the Premises and/or Building, and costs of furnishing water and
sewer services to the Premises and/or Building.

     The term "Building" as used in this Section 4.2 shall be deemed to include
not only the Building but also any parking facility owned, leased or operated by
Landlord in order to meet the parking requirements of the Building.

     If the average occupancy of the rentable area of the Building during the
Tenant's Base Year for Operating and Utility Costs as set forth in Section F on
page 2 or during any other calender year of the lease term is less than 90 % of
the total rentable area of the Building, the Operating Costs and Utility Costs
shall be adjusted by Landlord for such calendar year, prior to the pass-through
of Operating Costs and Utility Costs to Tenant pursuant to this Section 4.2, to
reflect what they would have been had 90% of the rentable area been occupied
during that year. In making such calculation, the Landlord's reasonable opinion
of what portion, if any, of each costs and affected by changes in occupancy
shall be binding upon the parties.

     5.    TAX ON TENANT'S PROPERTY; OTHER TAXES. 

     5.1   Tenants shall be liable for, and shall pay at least 10 days before
delinquency, and Tenant hereby indemnifies and holds Landlords harmless from
and against any personal property, fixtures, machinery, equipment, apparatus
systems and appurtenances placed by Tenant in or about, or utilized by Tenant
in, upon or in connection with, the Premises ("Equipment Taxes"). If any
Equipment Taxes are levied against Landlord or Landlord's property or if the
assessed value of Landlords property is increased by the inclusion therein of a
value placed upon such personal property, fixtures, machinery, equipment,
apparatus, systems or appurtenances of Tenant, and if Landlord, after written
notice to Tenant, pays the Equipment Taxes or taxes based upon such an increased
assessment (which Landlord shall have the right to do regardless of the validity
of such levy, but only under proper protest if requested by Tenant prior to such
payment and if payment under protest is permissible). Tenant shall pay to
Landlord upon demand, as additional rent hereunder, the taxes so levied against
Landlord or the proportion of such taxes resulting from such increased in the
assessment; provided however, that in any such event Tenant shall have the
right, in the name of Landlord and with Landlord's full cooperation, but at no
cost to Landlord, to bring suit in any court of competent jurisdiction to
recover the amount of such tax so paid under protest, and any amount so
recovered shall belong to Tenants.

     5.2   If the tenant improvements in the Premises, whether installed and/or
paid for by Landlord or Tenant and whether or not affixed to the real property
so as to become a part thereof, are assessed for real property tax purposes at a
valuation higher than the valuation at which tenant improvements conforming to
Landlord's building standards in other space in the Building are assessed, then
the real property taxes and assessments levied against Landlord or Landlord's
property by reason of such excess assessed valuation shall be deemed to be
Equipment Taxes and shall be governed by the provisions of Section 5.1. Any such
amounts, and any similar amounts attributable to excess improvements by other
tenants of the Building and Recovered by Landlords from such other tenants under
comparable lease provisions, shall not be included in Real Estate Taxes for
purposes of rent escalation under Section 4 of this Lease.

     5.3   Tenant shall pay, as additional rent hereunder, upon demand and in 
such manner and at such times as Landlord shall direct from time to time by
written notice to Tenant, any excise, sales, privilege or other tax, assessment
or other charge (other than income or franchise taxes) imposed, assessed or
levied by any governmental or quasi-governmental authority or agency upon
Landlord on account of this Lease, the rent or other payments made by Tenant

                                      6 
<PAGE>
 
hereunder, any other benefit received by Landlord hereunder, Landlord's business
as a lessor hereunder, or otherwise in respect of or as a result of the 
agreement or relationship of Landlord and Tenant hereunder.

     6.   SECURITY DEPOSIT.

     6.1  A deposit (the "Security Deposit") in the amount set forth in Section 
H on page 2 shall be paid by Tenant upon execution of this Lease and shall be 
held by Landlord without liability for interest and as security for the 
performance by Tenant of Tenant's covenants and obligations under this Lease, it
being expressly understood that the Security Deposit shall not be considered an 
advance payment of rent or a measure of Landlord's damages in case of default by
Tenant. Upon the occurrence of any breach or default under this Lease by Tenant,
Landlord may, from time to time, without prejudice to any other remedy, use the 
Security Deposit or any portion thereof to the extent necessary to make good any
arrearages of rent or any other damage, injury, expense, or liability caused to 
Landlord by such breach or default. Following any application of the Security 
Deposit, Tenant shall pay to Landlord on demand an amount to restore the 
Security Deposit to its original amount. In the event of bankruptcy or other 
debtor relief proceedings by or against Tenant, the Security Deposit shall be 
deemed to be applied first to the payment of rent and other charges due 
Landlord, in the order that such rent or charges become due and owing, for all 
periods prior to filing of such proceedings. Landlord shall not be required to 
keep the Security Deposit separate from its general funds. Upon termination of 
this Lease any remaining balance of the Security Deposit shall be returned by 
Landlord to Tenant within 14 days after termination of Tenant's tenancy.

     6.2  (Intentionally deleted.)

     7.   LATE PAYMENTS. All covenants and agreements to be performed by Tenant 
under any of the terms of this Lease shall be performed by Tenant at Tenant's 
sole cost and expense and without any abatement of rent. Tenant acknowledges 
that the late payment by Tenant to Landlord of any sums due under this Lease 
will cause Landlord to incur costs not contemplated by this Lease, the exact 
amount of such cost being extremely difficult and impractical to fix. Such costs
include, without limitation, processing and accounting charges, and late charges
that may be imposed on Landlord by terms of any note or other obligation secured
by any encumbrance covering the Premises or the Building of which the Premises 
are a part. Therefore, if any monthly installment of rent is not received by 
Landlord by the date when due, or if Tenant fails to pay any other sum of money 
due hereunder, Tenant shall pay to Landlord, as additional rent, the sum of ten 
percent (10%) of the overdue amount as a late charge. Landlord's acceptance of 
any late charge, or interest pursuant to Section 33.9, shall not be deemed to be
liquidated damages, nor constitute a waiver of Tenant's default with respect to 
the overdue amount, nor prevent Landlord from exercising any of the other rights
and remedies available to Landlord under this Lease or any law now or hereafter 
in effect. Further, in the event such late charge is imposed by Landlord for 2 
consecutive months for whatever reason, Landlord shall have the option to 
require that, beginning with the first payment of rent due following the 
imposition of the second consecutive late charge, rent shall no longer be paid 
in monthly installments but shall be payable 3 months in advance.

     8.   USE OF PREMISES. Tenant, and any permitted subtenant or assignee, 
shall use the Premises only for the use described in Section 1 on page 2. Any 
other use of the Premises is absolutely prohibited. Tenant shall not use or 
occupy the Premises in violation of any recorded covenants, conditions and 
restrictions affecting the land on which the Building is located nor of any law,
ordinance, rule and regulation. Tenant shall not do or permit to be done 
anything which will invalidate or increase the cost of any fire, extended 
coverage or any other insurance policy covering the Building or property located
therein and shall comply with all rules, orders, regulations and requirements of
any applicable fire rating bureau or other organization performing a similar 
function. Tenant shall promptly upon demand reimburse Landlord as additional 
rent for any additional premium charged for any issuance policy by reason of 
Tenant's failure to comply with the provision of this Section 8. Tenant shall 
not do or permit anything to be done in or about the Premises which will in any
way obstruct or interfere with the rights of other tenants of occupants of the 
Building, or injure or annoy them, or use or allow the Premises to be used for 
any improper, immoral, unlawful or objectionable purpose, nor shall Tenant 
cause, maintain or permit any nuisance in, on or about the Premises. Tenant 
shall not commit or suffer to be committed any waste in or upon the Premises and
shall keep the Premises in first class repair and appearance. Tenant shall not 
place a load upon the Premises exceeding the average pounds of live load per 
square foot of floor area specified for the Building by Landlord's architect, 
with any partitions to be considered a part of the live load. Landlord reserves 
the right to prescribe the weight and position of all safes, files and heavy 
equipment which Tenant desires to place in the Premises so as to distribute 
properly the weight thereof. Tenant's business machines and mechanical equipment
which cause vibration or noise that may be transmitted to the Building structure
or to any other space in the Building shall be so installed, maintained and used
by Tenant as to eliminate such vibration or noise. Tenant shall be responsible 
for the cost of all structural engineering required to determine structural 
load. In any event, unless specifically authorized herein, Tenant shall not 
prepare or serve, or authorize the preparation or service of, food or beverages 
in the Premises, except only the occasional preparation of coffee, tea, hot 
chocolate and other such common refreshments for Tenant and its employees. 
Tenant shall not conduct any auction in or about the Premises or the Building 
without Landlord's prior written consent.

     9.    BUILDING SERVICES.

     9.1   Throughout the term of this Lease, subject to shortage and accidents
beyond Landlord's reasonable control, and subject to reimbursement pursuant to
Section 4.2, Landlord shall repair and maintain all structural elements of the
Building and common areas (including, without limitation, the structural walls,
doors, floor, ceilings, roof, elevators, stairwells, lobby, heating system, air
conditioning system, telephone cable riser for Building-standard service from
the Building's main terminal to the terminal box on the same floor as the
Premises [but excluding Tenant's telephone equipment and the cable and wiring
from such equipment to the terminal box], plumbing and electrical wiring) and
maintain the exterior of the Premises, including grounds, walks, drives and
loading area, if any. Tenant shall reimburse Landlord upon demand as additional
rent hereunder, for the cost of any repairs or extraordinary maintenance
necessitated by acts of Tenant or Tenant's employees, contractors, agents,
licensees or invitees.

     9.2   Provided that Tenant is not in default hereunder, subject to
shortages and accidents beyond Landlord's reasonable control, Landlord shall
furnish building standard heating and air conditioning service Monday through
Friday from 8:00 A.M. to 6:00 P.M., and Saturday from 8:00 A:M. to 1:00 P.M.,
except for holidays. No heating or air conditioning will be furnished by
Landlord on Sundays, holidays or during hours other than as set forth above,
except upon prior arrangement with Tenant and at an extra charge as may be
agreed to between Landlord and Tenant. For purposes of this Section 9.2,
"holidays" shall mean and refer to the holidays of Christmas, New Year's Day,
President's Day, Memorial Day, the Fourth of July, Labor Day, Thanksgiving and
the day after Thanksgiving, as those holidays are defined, recognized or
established by governmental authorities or agencies from time to time and such
other days the New York Stock Exchange is closed. Tenant shall install, at its
expense, such additional air conditioning equipment as may be reasonably
determined by Landlord to be necessary in order to maintain building air
conditioning standards resulting from Tenant's installation and operation of
computer equipment or other special equipment or facilities placing a greater
burden on the air conditioning system than would general office use. Landlord
shall furnish electric current to the Premises in amounts reasonably sufficient
for normal business use, including operation of building standard lighting and
operation of typewriters and standard fractional horsepower office machinery.
Tenant agrees that, at all times during the term of this Lease, Tenant's use of
electric current shall never exceed the capacity of the feeders to the Building
or the risers or wiring installation in the Building. Tenant shall not install
or use or permit the installation or use upon or about the Premises of any
computer or electronic data processing or other equipment using current in
excess of 110 volts or requiring power in excess of 500 watts, without the
express prior written consent of Landlord. Tenant shall pay monthly upon billing
as additional rent under this Lease such sums as Landlord's building engineer
may reasonably determine to be necessary in order to reimburse Landlord for the
additional cost of utilities (including, without limitation, electricity, gas
and other fuels or power sources, and water, and Landlord's reasonable costs of
administration) attributable to the operation of additional air conditioning
equipment and any other requirements in excess of those for normal office use by
reason of the operation of computer equipment or other special equipment or
facilities, or attributable to Tenant's conducting business beyond the business
hours described in the first sentence of this Section 9.2. Moreover, at
Landlord's election, Landlord may separately meter at Tenant's expense the
electrical usage of some or all of Tenant's equipment, facilities or Premises.
In such event Tenant shall pay the charges for all such separately metered
electrical usage within 10 days after receipt of a billing therefor. Any such
amounts billed directly to Tenant shall not be included in the Building's
"Utility Costs" for purposes of Section 4 above. Any extra maintenance charges
or service calls attributable to the actions of Tenant (e.g., continual
                                                        ---
adjustments of the thermostats or the failure to keep window coverings closed as
necessary) shall be payable by Tenant to Landlord upon demand, as additional
rent hereunder.

     9.3   Landlord shall furnish unheated water from mains for drinking,
lavatory and toilet purposes drawn through fixtures installed by Landlord, or by
Tenant with Landlord's express prior written consent, and heated water for
lavatory purposes from regular building supply in such quantities as required in
Landlord's judgement for the comfortable and normal use of the Premises. Tenant
shall pay Landlord for additional water which is furnished for any other
purpose. The amount that Tenant shall pay Landlord for such additional water
shall be the average price per gallon charged to the Landlord for the Building
by the entity providing water, increased by 25% to cover Landlord's
administrative expense.

     9.4   Landlord shall furnish janitor service (including washing of windows
with reasonable frequency as determined by Landlord) in and about the Premises,
to the extent necessitated by normal office use of the Premises, Monday through
Friday, holidays excepted. Landlord shall have no obligation to furnish janitor
service for any portion of the Premises which is occupied after 7:00 p.m., is
locked or may be used (to the extent permitted under this Lease) for the
preparation, dispensing or consumption of food or beverages or for any purpose
other than general office use, and Tenant shall keep all such portions of the
Premises in a clean and orderly condition at Tenant's sole cost and expense. In
the event that Tenant shall fail to keep such portions of the Premises in a
clean and orderly condition, Landlord may do so and any costs incurred by
Landlord in connection therewith shall be payable by Tenant to Landlord upon
demand, as additional rent hereunder. Tenant shall also pay to Landlord, as
additional rent hereunder, amounts equal to any increase in cost of janitor
service in and about the Premises if such increase in costs is due to (a) use of
the Premises by Tenant during hours other

                                       8

than normal business hours, or (b) location in or about the Premises of any
fixtures, improvements, materials or finish items (including without limitation
wall coverings and floor coverings) other than those which are of the standard
type adopted by Landlord for the Building. Only those persons who have been
approved by Landlord may perform janitorial services.

     9.5   Landlord shall furnish passenger and freight elevator service in
common with Landlord and other tenants Monday through Friday from 8:00 A.M. to
6.00 P.M. and Saturday from 8:00 A.M. to 1:00 P.M. Landlord shall provide
limited passenger elevator service daily at all times such normal passenger
service is not furnished.

     9.6   Landlord does not warrant that any service will be free from
interruptions caused by repairs, renewals, improvements, changes of service,
alterations, strikes, lockouts, labor controversies, accidents, inability to
obtain fuel, steam, water or supplies or other cause, provided the cause is
beyond the reasonable control of Landlord. Landlord agrees to give Tenant notice
of any extended interruptions of which Landlord has prior knowledge. No
interruption of service shall be deemed an eviction or disturbance of Tenant's
use and possession of the Premises or any part thereof, nor relieve Tenant from
performance of Tenant's obligations under this Lease. Landlord shall not be
liable for any failure to make such repairs or furnish such services unless the
failure shall be reasonably curable by Landlord and nonetheless shall persist
for an unreasonable time after written notice from Tenant of the need for such
repairs or the failure to furnish such service. There shall be no abatement of
rent and no liability of Landlord by reason of any injury to or interference
with Tenant's business arising from the making of any repairs, alterations or
improvements, or provision of any service in or to any portion of the Building,
including the Premises, or in or to the fixtures, appurtenances and equipment
therein; provided that in making such repairs, alterations or improvements or
providing such service Landlord shall interfere as little as reasonably
practicable with the conduct of Tenant's business in the Premises, without,
however, being obligated to incur liability for overtime or other premium
payment to its agents, employees or contractors in connection therewith. If
Tenant's beneficial use of all or a substantial portion of the Premises is
prevented for a period in excess of 3 consecutive business days (excluding
Saturdays, Sundays, and holidays), the Base Rent shall be equitably abated
commencing with the fourth business day and continuing until such use is no
longer prevented. Such abatement, to the extent provided above, shall be
Tenant's sole remedy. Except as provided above, Tenant shall not be entitled to
any abatement or reduction of rent or other remedy by reason of Landlord's
failure to furnish any of the services or Building systems called for by this
Lease when such failure is caused by accident, breakage, repairs, strikes,
lockouts or other labor disturbances or labor disputes of any character, or any
other cause. As a material inducement to Landlord's entry into this Lease,
Tenant waives and releases any rights it may have to make repairs at Landlord's
expense under Sections 1941 and 1942 of the California Civil Code.

     10.   CONDITIONS OF PREMISES. By occupying the Premises, Tenant shall be
deemed to accept the same and acknowledge that they comply fully with Landlord's
covenants and obligations hereunder, subject to completion of any items which it
is Landlord's responsibility hereunder to furnish and which are listed by
Landlord and Tenant upon inspection of the Premises. Tenant acknowledges that
neither Landlord nor any agent, employee or representative of Landlord has made
any representation or warranty with respect to any matter, including but not
limited to any matter regarding the Building or Premises, the applicable zoning
or the effect of other applicable laws, or the suitability or fitness of the
Building or Premises for the conduct of Tenant's business or any other purpose.
Tenant is relying solely on its own investigations with respect to all such
matters. During the term of this Lease, Tenant shall maintain the Premises in as
good condition as when Tenant took possession, ordinary wear and tear and
repairs which are specifically made the responsibility of Landlord hereunder
excepted, and shall repair all damage or injury to the Building or to fixtures,
appurtenances and equipment of the Building caused by Tenant's installation or
removal of its property or resulting from the negligence or tortious conduct of
Tenant, its employees, contractors, agents, licensees and invitees. In the event
of failure by Tenant to perform its covenants of maintenance and repair
hereunder, Landlord may perform such maintenance and repair, and any amounts
expended by Landlord in connection therewith shall be payable by Tenant to
Landlord upon demand, as additional rent hereunder.

     11.   DAMAGE TO PREMISES OR BUILDING.

     11.1  In the event that the Building should be totally destroyed by fire or
other casualty, this Lease shall terminate. In the event the Premises or a
substantial portion of the Building should be so damaged or destroyed that
rebuilding or repairs cannot, in Landlord's opinion, be completed within 180
days after the date of such damage or Landlord will not receive insurance
proceeds sufficient to cover the costs of such repairs, reconstruction and
restoration (including proceeds from Tenant and/or Tenant's insurance which
Tenant is required to deliver to Landlord pursuant to Subsection 11.2 below),
Landlord may at its option terminate this Lease upon notice to Tenant, or
Landlord may proceed to restore the Building. In the event that such rebuilding
or repairs can, in Landlord's opinion, be completed within 180 days after the
date of such damage and Landlord will receive insurance proceeds sufficient to
cover the costs of such repairs, reconstruction and restoration (including
proceeds from Tenant and/or Tenant's insurance which Tenant is required to
deliver to Landlord pursuant to Subsection 11.2 below), Landlord shall restore
the Building. In the event that Landlord is obligated or elects to restore the
Building, Landlord shall commence to rebuild or repair the Building reasonably
promptly after such

                                       9

<PAGE>
 
damage or destruction and shall proceed with reasonable diligence to restore it 
to substantially the condition in which it was immediately prior to the 
casualty, except that Landlord shall not be required to rebuild, repair or 
replace any part of the partitions, fixtures, alterations, decorations or other 
Improvements which may have been constructed by or specifically for Tenant 
(except the improvements built by Landlord pursuant to the Landlord's 
Improvement Construction Rider, which Landlord shall restore), or by or for 
other tenants within the Building. In such event this Lease shall remain in full
force and effect, provided that if Tenant is dispossessed by reason of such 
casualty from all or a substantial portion of the Premises for more than 3 
consecutive business days, Tenant shall be entitled to a ratable abatement of 
the Base Rent during the time and to the extent the Premises are unfit for 
occupancy, commencing with the fourth business day; and provided further that 
Tenant shall have the right to terminate this Lease upon notice served upon 
Landlord prior to actual completion of any necessary restoration of the Premises
if such restoration is not substantially completed within 360 days after the 
casualty. Such abatement or termination, to the extent provided above, shall be 
Tenant's sole remedy. Notwithstanding the foregoing to the contrary, if the 
damage is due to the negligence or wilful misconduct of Tenant or any of 
Tenant's agents, employees or invitees, there shall be no abatement of rent. 
Except for abatement of rent as provided hereinabove, Tenant shall not be 
entitled to any compensation or damages for loss of, or interference with, 
Tenant's business or use or access of all or any part of the Premises resulting 
from any such damage, repair, reconstruction or restoration.

     11.2  In the event of any damage or destruction of all or any part of the 
Premises, Tenant shall immediately; (a) notify Landlord thereof; and (b) deliver
to Landlord all insurance proceeds received by Tenant with respect to the 
Leasehold improvements and Tenant changes in the Premises to the extent such 
items are not covered by Landlord's casualty insurance (excluding proceeds for 
Tenant's furniture and other personal property), whether or not this Lease is 
terminated as permitted in this Section 11, and Tenant hereby assigns to 
Landlord all rights to receive such insurance proceeds. If, for any reason 
(including Tenant's failure to obtain insurance for the full replacement cost of
any Tenant changes which Tenant is required to insure pursuant to this Lease), 
Tenant fails to receive insurance proceeds covering the full replacement cost of
such Tenant changes which are damaged, Tenant shall be deemed to have 
self-insured the replacement cost of such tenant changes, and upon any damage or
destruction thereof, Tenant shall immediately pay to Landlord the full 
replacement cost of such items, less any insurance proceeds actually received by
Landlord from Landlord's or Tenant's insurance with respect to such items.

     11.3  In the event any holder of a mortgage or deed of trust on the 
Building should require that the insurance proceeds payable upon damage or 
destruction to the Building by fire or other casualty be used to retire the debt
secured by such mortgage or deed of trust, or in the event any lessor under any 
underlying or ground lease should require that such proceeds be paid to such 
lessor, Landlord shall in no event have any obligation to rebuild, and at 
Landlord's election this Lease shall terminate.

     11.4  With the exception of insurance required to be carried by Tenant 
under Section 28 of this Lease, and except as provided in Section 11.2, any 
insurance which may be carried by Landlord or Tenant against loss or damage to 
the Building or to the Premises shall be for the sole benefit of the party 
carrying such insurance and under its sole control. Landlord shall not be 
required to carry insurance of any kind on Tenant's property and, except by 
reason of the breach by Landlord of any of its obligations hereunder, shall not 
be obligated to repair any damage thereto or to replace the same.

     11.5  In addition to its termination rights in Subsection 11.1 above, 
Landlord shall have the right to terminate this Lease if any damage to the 
Building or Premises occurs during the last 12 months of the Term of this Lease 
and Landlord estimates that the repair, reconstruction or restoration of such 
damage cannot be completed within the earlier of (a) the scheduled expiration
date of the Lease Term, or (b) 60 days after the date of such casualty.

     11.6  Tenant, as a material inducement to Landlord's entering into this 
Lease, irrevocably waives and releases its rights under the provisions of 
Sections 1932(2) and 1933(4) of the California Civil Code (and any successor 
statutes permitting Tenant to terminate this Lease as a result of any damage or 
destruction), it being the intention of the parties hereto that the express 
terms of this Lease shall control under any circumstances in which those 
provisions might otherwise apply.

     12.   EMINENT DOMAIN.

     12.1  In the event that the whole of the Premises, or so much thereof as to
render the balance unusable to Tenant for the purposes leased hereunder, as
reasonably determined by Landlord, shall be lawfully condemned or taken in any
manner for any public or quasi-public use, or conveyed by Landlord in lieu
thereof (a "Taking"), this Lease and the term hereby granted shall forthwith
cease and terminate on the date of the taking possession by of the condemning
authority (the "Date of Taking").

                                      10
<PAGE>
 
     12.2   In the event of a taking of a portion of the Premises which does not
result in the termination of this Lease pursuant to Section 12.1, above, the
Base Rent shall be abated in proportion to the part of the Premises so taken.

     12.3   In the event that there is a Taking of a portion of the Building
other than the Premises, and if, in the opinion of Landlord, the Taking is so
substantial as to render the remainder of the Building uneconomic to maintain
despite reasonable reconstruction or remodeling, or if it would be necessary to
alter the Building or Premises materially, Landlord may terminate this Lease by
notifying Tenant of such termination within 60 days following the Date of
taking, and this Lease shall end on the date specified in the notice of
termination, which shall not be less than 60 days after the giving of such
notice.

     12.4   No temporary Taking of the Building or Premises and/or of Tenant's
rights therein or under this Lease shall terminate this Lease or give Tenant any
right to abatement of rent hereunder. Tenant shall be entitled to receive such
portion or portions of any award made for the temporary use with respect to the
period of the taking which is within the term of this Lease, provided that, if
such taking shall remain in force at the expiration or earlier termination of
this Lease, then Tenant shall pay to Landlord a sum equal to the reasonable
costs of performing Tenant's obligations under Section 15 with respect to
Tenant's surrender of the Premises and, upon such payment, shall be excused from
such obligations. For purposes of this Section 12.4, a temporary taking shall be
defined as a taking for a period of 270 days or less.

     12.5   Except for the award in the event of a temporary Taking as
contemplated in Section 12.4, above, Tenant hereby releases and shall have no
interest in, or right to participate with respect to the determination of, any
compensation for any Taking, except only that Tenant shall be entitled to the
portion of any award specifically designated by the condemning authority to be
for any personal property of Tenant included in any such Taking or for any
relocation expenses or business interruption loss incurred by Tenant.

     13.    DEFAULT.

     13.1   The following events shall be deemed to be events of default by 
Tenant under this Lease:

            (a)     If Tenant shall fail to pay any installment of rent or any 
other sum required to be paid by Tenant under this Lease as due.

            (b)     If Tenant shall fail to comply with any term, provision or 
covenant of this Lease, other than provisions pertaining to the payment of 
money.

            (c)     If Tenant shall make an assignment for the benefit of 
creditors.

            (d)     If Tenant shall file a petition under any section or chapter
of the federal Bankruptcy Code, as amended from time to time, or under any 
similar law or statute of the United States or any State thereof pertaining to 
bankruptcy, insolvency or debtor relief, or Tenant shall have a petition or 
other proceedings filed against Tenant under any such law or chapter thereof and
such petition or proceeding shall not be vacated or set aside within 60 days
after such filing.

            (e)     If a receiver or trustee shall be appointed for all or 
substantially all of the assets of Tenant and such receivership shall not be 
terminated and possession of such assets restored to Tenant within 30 days after
such appointment.

            (f)     If Tenant shall desert or vacate any substantial portion of 
the Premises and the same shall remain unoccupied for more than 14 days 
thereafter.

            (g)     If Tenant shall assign this Lease or sublet the Premises in 
violation of the terms hereof.

     13.2   Any shorter period for cure provided by law notwithstanding, and in 
lieu thereof, including without limitation California Code of Civil Procedure 
Section 1161, Tenant may cure any monetary default under Subsection 13.1(a), 
above, at any time within 5 days after written notice of default is received by 
Tenant from Landlord; and (except as specifically provided otherwise in Section 
24) Tenant may cure any non-monetary default within 15 days after written notice
of default is received by Tenant from Landlord, provided that if such 
non-monetary default is curable but is of such a nature that the cure cannot be 
completed within 15 days, Tenant shall be allowed to cure the default if Tenant 
promptly commences the cure upon receipt of the notice and diligently prosecutes
the same to completion, which completion shall occur not later than 60 days 
from the date of such notice from Landlord.

                                      11

     14.   REMEDIES UPON DEFAULT.

     14.1  Upon the occurrence of any event of default by Tenant, Landlord shall
have, in addition to any other remedies available to Landlord at law or in
equity, the option to pursue any one or more of the following remedies (each and
all of which shall be cumulative and non-exclusive) without any notice or demand
whatsoever:

           (a)  Terminate this Lease, in which event Tenant shall immediately 
surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, 
without prejudice to any other remedy which it may have for possession or 
arrearages in rent, enter upon and take possession of the Premises and expel or 
remove Tenant and any other person who may be occupying the Premises or any part
thereof, without being liable for prosecution or any claim or damages therefor; 
and Landlord may recover from Tenant the following:

                (1)  The worth at the time of award of any unpaid rent which has
been earned at the time of such termination; plus

                (2)  The worth at the time of award of the amount by which the
unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that Tenant proves could have been
reasonably avoided; plus

                (3)  The worth at the time of award of the amount by which the 
unpaid rent for the balance of the term after the time of award exceeds the 
amount of such rental loss that Tenant proves could have been reasonably 
avoided; plus

                (4)  Any other amount necessary to compensate Landlord for all 
the detriment proximately caused by Tenant's failure to perform its obligations 
under this Lease or which in the ordinary course of things would be likely to 
result therefrom, specifically including but not limited to attorney's fees, 
removal and storage (or disposal) of Tenant's personal property, unreimbursed 
leasehold improvement costs (e.g., the amounts Landlord has expended for 
leasehold improvements which have not been recovered as of the termination of 
the Lease when amortized on a straight-line basis over the originally scheduled 
lease term), brokerage commissions and advertising expenses incurred, expenses 
of remodeling the Premises or any portion thereof for a new tenant, whether for 
the same or a different use, and any special concessions made to obtain a new 
tenant; and

                (5)  At Landlord's election, such other amounts in addition to 
or in lieu of the foregoing as may be permitted from time to time by applicable 
law.

The term "rent" as used in this Subsection 14.1(a) shall be deemed to be and to 
mean all sums of every nature required to be paid by Tenant pursuant to the 
terms of this Lease, whether to Landlord or to others. Any such sums which are 
based on percentages of income, increased costs or other historical data shall 
be reasonable estimates or projections computed by Landlord on the basis of the 
amounts thereof accruing during the 24-month period immediately prior to 
default, except that if it becomes necessary to compute such sums before a 
24-month period has expired, then the computation shall be made on the basis of 
the amounts accruing during such shorter period. As used in Subsections 
14.1(a)(1) and (2), above, the "worth at the time of award" shall be computed by
allowing interest from the date the sums became due at the lesser of (i) the 
Bank of America prime rate on the due date plus 6%, or (ii) the maximum rate 
permitted by law. As used in Subsection 14.1(a)(3), above, the "worth at the 
time of award" shall be computed by discounting such amount at the discount 
rate of the Federal Reserve Bank of San Francisco at the time of award plus 1%.

           (b)  In the event of any such default by Tenant, in addition to any 
other remedies available to Landlord under this Lease, at law or in equity, 
Landlord shall also have the right, with or without terminating this Lease, to 
re-enter the Premises and remove all persons and property from the Premises; 
such property may be removed, stored and/or disposed of pursuant to any 
procedures permitted by applicable law, including but not limited to those 
described in Section 15.3. No re-entry or taking possession of the Premises by 
Landlord pursuant to this Subsection 14.1(b), and no acceptance of surrender of 
the Premises or other action on Landlord's part, shall be construed as an 
election to terminate this Lease unless a written notice of such intention be 
given to Tenant or unless the termination thereof be decreed by a court of 
competent jurisdiction.

           (c)  In the event of any such default by Tenant, in addition to any 
other remedies available to Landlord under this Lease, at law or in equity, 
Landlord shall have the right to continue this Lease in full force and effect, 
whether or not Tenant shall have abandoned the Premises. The foregoing remedy 
shall also be available to Landlord pursuant to California Civil Code Section 
1951.4 and any successor statute in the event Tenant has abandoned the Premises.
In the event Landlord elects to continue this Lease in full force and effect 
pursuant to this Subsection 14.1(c), then Landlord shall 

                                      12
<PAGE>
 
be entitled to enforce all of its rights and remedies under this Lease, 
including the right to recover rent as it becomes due. Landlord's election not 
to terminate this Lease pursuant to this Subsection 14.1(c) or pursuant to any 
other provision of this Lease, at law or in equity, shall not preclude Landlord 
from subsequently electing to terminate this Lease or pursuing any of its other 
remedies.

          (d)  Whether or not Landlord elects to terminate this Lease on account
of any default by Tenant, Landlord shall have the right to terminate any and all
subleases, licenses, concessions or other consensual arrangements for possession
entered into by Tenant and affecting the Premises or may, in Landlord's sole 
discretion, succeed to Tenant's interest in such subleases, licenses, 
concessions or arrangements. If Landlord so elects to succeed to Tenant's 
interest, Tenant shall, as of the date of notice by Landlord of such election, 
have no further right to or interest in the rent or other consideration 
receivable thereunder.

     14.2 Following the occurrence of an event of default by Tenant, Landlord 
shall have the right to require that any or all subsequent amounts paid by 
Tenant to Landlord hereunder, whether in cure of the default in question or 
otherwise, be paid in the form of cash, money order, cashier's or certified 
check drawn on an institution acceptable to Landlord, or by other means approved
by Landlord, notwithstanding any prior practice of accepting payments in any 
different form.

     14.3 All rights, options and remedies of Landlord contained in this Section
14 and elsewhere in this Lease shall be construed and held to be cumulative, and
no one of them shall be exclusive of the other, and Landlord shall have the 
right to pursue any one or more of such remedies or any other remedy or relief 
which may be provided by law or in equity, whether or not stated in this Lease. 
Nothing in this Section 14 shall be deemed to limit or otherwise affect Tenant's
indemnification of Landlord pursuant to any provision of this Lease.

     14.4 Landlord shall not be deemed in default in the performance of any 
obligation required to be performed by Landlord under this Lease unless Landlord
has failed to perform such obligation within 30 days after the receipt of 
written notice from Tenant specifying in detail Landlord's failure to perform; 
provided however, that if the nature of Landlord's obligation is such that more 
than 30 days are required for its performance, then Landlord shall not be deemed
in default if it commences such performance within such 30-day period and 
thereafter diligently pursues the same to completion. Upon any such uncured 
default by Landlord, Tenant shall be entitled, as Tenant's sole and exclusive 
remedy, to recover from Landlord Tenant's actual damages (but not lost profits 
or other incidental or consequential damages) shown by Tenant to have been 
directly caused thereby; provided, however; (a) Tenant shall have no right to 
offset or abate rent in the event of any default by Landlord under this Lease, 
except to the extent offset rights are specifically provided to Tenant in this 
Lease; (b) Tenant shall in no event be entitled to terminate this Lease by 
reason of Landlord's default; and (c) Tenant's rights and remedies hereunder 
shall be limited to the extent Tenant has expressly waived in this Lease any of 
such rights or remedies, including the limitation on Landlord's liability 
contained in Section 33.17 hereof.

     14.5 No waiver by Landlord or Tenant of any violation or breach of any of 
the terms, provisions and covenants herein contained shall be deemed or 
construed to constitute a waiver of any other or later violation or breach of 
the same or any other of the terms, provisions, and covenants herein contained. 
Forbearance by Landlord in enforcement of one or more of the remedies herein 
provided upon an event of default shall not be deemed or construed to constitute
a waiver of such default. The acceptance of any rent hereunder by Landlord 
following the occurrence of any default, whether or not known to Landlord, shall
not be deemed a waiver of any such default, except only a default in the payment
of the rent so accepted, subject to the provisions of Section 33.1.

     15.  SURRENDER OF PREMISES; REMOVAL OF PROPERTY.

     15.1 No act or thing done by Landlord or any agent or employee of Landlord 
during the term hereof shall be deemed to constitute an acceptance by Landlord 
of a surrender of the Premises unless such intent is specifically acknowledged 
in a writing signed by Landlord. The delivery of keys to the Premises to 
Landlord or any agent or employee of Landlord shall not constitute a surrender 
of the Premises or effect a termination of this Lease, whether or not the keys 
are thereafter retained by Landlord, and notwithstanding such delivery Tenant 
shall be entitled to the return of such keys at any reasonable time upon request
until this Lease shall have been properly terminated. The voluntary or other 
surrender of this Lease by Tenant, whether accepted by Landlord or not, or a 
mutual termination hereof, shall not work a merger, and at the option of 
Landlord shall operate as an assignment to Landlord of all subleases or 
subtenancies affecting the Premises.

     15.2 Upon the expiration of the term of this Lease, or upon any earlier 
termination of this Lease, Tenant shall, subject to the provisions of this 
Section 15, quit and surrender possession of the Premises to Landlord in as good
order and condition as when Tenant took possession and as thereafter improved by
Landlord and/or Tenant, reasonable wear and tear and repairs which are 
specifically made the responsibility of Landlord hereunder excepted. Upon such 
expiration or 

                                      13
<PAGE>
 
termination, Tenant shall, without expense to Landlord, remove or cause to be 
removed from the Premises all debris and rubbish, and such items of furniture, 
equipment, free-standing cabinet work, movable partitions and other articles of 
personal property owned by Tenant or installed or placed by Tenant at its 
expense in the Premises, and such similar articles of any other persons claiming
under Tenant, as Landlord may, in its sole discretion, require to be removed, 
and Tenant shall repair at its own expense all damage to the Premises and
Building resulting from such removal.

     15.3 Whenever Landlord shall re-enter the Premises as provided in this 
Lease, any personal property of Tenant not removed by Tenant upon the expiration
of the term of this Lease, or within 48 hours after a termination by reason of 
Tenant's default as provided in this Lease, shall be deemed abandoned by Tenant 
and may be disposed of by Landlord (without liability to Tenant) in accordance 
with Sections 1980 through 1991 of the California Civil Code and Section 1174 of
the California Code of Civil Procedure, or in accordance with any laws or 
judicial decisions which may supplement or supplant those provisions from time 
to time, or in accordance with any other legally permissible procedure, whether 
by public or private sale or otherwise. Landlord shall be entitled to apply any 
proceeds of the sale of such items to any sums due to Landlord by Tenant and to 
Landlord's costs of removal, storage and sale of such items. Alternatively, 
Landlord shall be entitled to treat Tenant's failure to remove such items from 
the Premises as either a permitted or unpermitted holdover pursuant to Section 
19 of this Lease.

     15.4 All fixtures, alterations, additions, repairs, improvements and/or 
appurtenances attached to or built into or on or about the Premises prior to or 
during the term hereof, whether by Landlord at its expense or at the expense of 
Tenant, or by Tenant at its expense, or by previous occupants of the Premises, 
shall be and remain part of the Premises and shall not be removed by Tenant at 
the end of the term of this Lease. Such fixtures, alterations, additions, 
repairs, improvements and/or appurtenances shall include, without limitation, 
floor coverings, drapes, paneling, molding, doors, kitchen and dishwashing 
fixtures and equipment, plumbing systems, electrical systems, lighting systems, 
silencing equipment, communication systems, all fixtures and outlets for the 
systems mentioned above and for all telephone, radio, telegraph and television 
purposes, and any special flooring or ceiling installations. Notwithstanding the
foregoing, Landlord may, in its sole discretion, require Tenant, at Tenant's 
sole cost and expense, to remove any fixtures, alterations, additions, repairs, 
improvements and/or appurtenances attached or built into or on or about the 
Premises, and to repair any damage to the Building and Premises occasioned by 
the installation, construction, operation and/or removal of such fixtures, 
equipment, alterations, additions, repairs, improvements and/or appurtenances. 
If Tenant shall fail to complete such removal and repair such damage, Landlord 
may do so and may charge the reasonable cost thereof to Tenant.

     15.5 Tenant hereby waives all claims for damages or other liability in
connection with Landlord's re-entering and taking possession of the Premises or
removing, retaining, storing or selling the property of Tenant as herein
provided, and Tenant hereby indemnifies and holds Landlord harmless from any
such damages or other liability, and no such re-entry shall be considered or
construed to be a forcible entry.

     16.  COSTS OF SUIT; ATTORNEYS' FEES; WAIVER OF JURY TRIAL.

     16.1 If Tenant or Landlord shall bring any action for any relief, 
declaratory or otherwise, against the other arising out of or under this Lease, 
including any suit by Landlord for the recovery of rent or possession of the 
Premises, the losing party shall pay the successful party its costs of suit, 
including, without limitation, a reasonable sum for attorneys' and other 
professional fees relating to such suit, and such fees shall be deemed to have 
accrued on the commencement of such action and shall be paid whether or not such
action is contested or prosecuted to judgment.

     16.2 In the event that Landlord shall, without fault of Landlord's part, be
made party to any litigation instituted by Tenant or by any third party against
Tenant, or by or against any person holding under or using the Premises by
license of Tenant, or for the foreclosure of any lien for labor or material
furnished to or for Tenant or of any such other person, Tenant hereby
indemnifies and holds Landlord harmless from and against all costs and expenses,
including reasonable attorneys' fees, incurred by Landlord in or in connection
with such litigation.

     16.3 In order to limit the cost of resolving any disputes between the 
parties, and as a material inducement to each party to enter into this Lease, 
each party hereby waives the right to a jury trial with respect to any 
litigation between the parties arising out of this Lease, Tenant's occupancy of 
the Premises, or Landlord's ownership, operation or management of the Building, 
irrespective of any rights to a jury trial which either party otherwise then 
would have under applicable statutes, constitutions, judicial decisions or other
laws.

     17.   ASSIGNMENT AND SUBLETTING.

     17.1  Except as hereinafter provided, Tenant shall not sublet all or any 
part of the Premises, nor assign this Lease, nor enter any license, "co-location
agreement" or other agreement permitting a third party (other than Tenant's 
employees and occasional guests) to use or occupy any portion of the Premises, 
without Landlord's express prior written consent, which consent shall not 
unreasonably be withheld. (For purposes of the balance of this Section 17.1 and 
Sections 17.2 through 17.4, the term "sublease" shall be deemed to include 
licenses, co-location agreements, and other agreements for use or occupancy of 
the Premises as described in the preceding sentence. The terms "subtenant" and 
"sublet" shall be construed accordingly.)

     In order to assist Landlord in evaluating any proposed assignment or 
sublease, Tenant agrees to provide Landlord with the proposed subtenant or 
assignee's current financial statement and financial statements for the 
preceding 2 years and such other information concerning the business background 
and financial condition of the proposed subtenant or assignee and of Tenant as 
Landlord may reasonably request.

     Landlord and Tenant hereby agree that Landlord's disapproval of any 
proposed sublease or assignment hereunder shall be deemed reasonable if based 
upon any reasonable factor, including, without limitation, any or all of the 
following factors:

           (a)  The proposed transfer would result in more than two subleases of
portions of the Premises being in effect at any time during the term;

           (b)  The rent payable by the proposed transferee would be less than 
the fair market rental value for the space as determined pursuant to the last 
paragraph of this Section 17.1;

           (c)  The proposed transferee is an existing tenant or occupant of the
Building or has negotiated with Landlord within the last twelve months for space
in the Building or is another transferee prohibited by the next to last 
paragraph of this Section 17.1;

           (d)  The proposed transferee is a governmental entity;

           (e)  The transaction calls for new demising walls to be built, and 
the portion of the Premises proposed to be sublet or assigned is irregular in 
shape and/or has inadequate means of ingress and egress;

           (f)  The use of the Premises by the proposed transferee (i) is not 
permitted by the use provisions of this Lease, or (ii) might, in Landlord's 
reasonable opinion, violate any right for an exclusive use granted by Landlord 
to another Tenant in the Building;

           (g)  The transfer would likely result, in Landlord's reasonable 
opinion, in a significant increase in the use of the parking areas or common 
areas of the Building due to the transferee's employees or visitors, and/or 
significant increase in the demand for utilities and services to be provided by 
Landlord to the Premises;

           (h)  The assignee or subtenant does not, in Landlord's reasonable 
opinion, have the financial capability to fulfill the obligations imposed by the
transfer, or in the case of an assignment, the assignee does not, in Landlord's 
reasonable opinion, have income and net worth at least equal to that of Tenant;

           (i)  The transferee is not, in the Landlord's reasonable opinion, of 
reputable or good character or consistent with Landlord's desired tenant mix;

           (j)  The transferee is a real estate developer or landlord or is 
acting directly or indirectly on behalf of a real estate developer or landlord;

           (k)  The proposed transferee may, in Landlord's reasonable opinion, 
increase the chances of significant hazardous waste contamination within the 
Premises or the Building;

           (l)  In the reasonable judgment of the Landlord, the purpose for 
which the transferee intends to use the Premises is not in keeping with the 
standards of the Landlord for the Building or is in violation of the terms of 
any other lease in the Building; or

           (m)  Landlord has not leased 95% of the rentable area in the 
Building.

                                      15

     Notwithstanding the foregoing, Tenant may, subject to the rest of the 
terms hereof, sublet all of the Premises or assign this Lease to any entity 
controlling, controlled by or under common control with Tenant, (including 
assignment or subletting to any corporation resulting from a merger or 
consolidation with Tenant, or to any person or entity which acquires all the 
assets of Tenant's business as a going concern) provided that, with regard to 
each such assignment or subletting: (A) Landlord receives the financial 
statements prescribed above and such other financial and background information 
as Landlord may request regarding the assignee or subtenant at least 20 days 
prior to such proposed assignment or sublease; (B) the Landlord determines, in 
its reasonable discretion, that the income and net worth of the assignee or 
subtenant comply with the standards prescribed in item (h) above; (C) the use of
the Premises is not altered; (D) the Landlord determines, in its sole and 
absolute discretion, that the transaction is not being entered into as a 
subterfuge to avoid the restrictions on assignment and subletting in the Lease; 
and (E) the subtenant or assignee expressly assumes the obligations of Tenant 
hereunder as prescribed below in this Section 17.1.

     Neither this Lease nor the term hereby demised shall be mortgaged by 
Tenant, nor shall Tenant mortgage, assign, pledge or otherwise transfer the 
interest of Tenant in and to any sublease or the rentals payable thereunder or 
in the Security Deposit.

     Any sublease, assignment, mortgage, pledge, encumbrance, or transfer made 
in violation of this Section 17.1 shall be void and at Landlord's election shall
terminate this Lease.

     Each subtenant, assignee or transferee of Tenant, other than Landlord, 
shall assume all obligations of Tenant under this Lease and shall be and remain 
liable jointly and severally with Tenant for the payment of the rent, and for 
the due performance of all the terms, covenants, conditions and agreements 
herein contained on Tenant's part to be performed for the term of this Lease 
(provided that in the case of a sublease, the subtenant's obligations shall be 
limited to those obligations relating to the subleased space and the common 
areas during the sublease term). No sublease or assignment shall be deemed 
approved by Landlord unless such subtenant or assignee and Tenant shall deliver 
to Landlord a counterpart of such sublease or assignment and an instrument in a 
form acceptable to Landlord, which contains a covenant of assumption by the 
subtenant or assignee satisfactory in substance and form to Landlord, consistent
with the requirements of this Section 17.1, but the failure or refusal of the 
subtenant or assignee to execute such instrument or assumption shall not release
or discharge the subtenant or assignee from its liability as set forth above.

     No subtenant or assignee not complying with the foregoing requirements 
shall have any interest in the Security Deposit. Any assignee that does 
comply with the foregoing requirements shall automatically succeed to Tenant's 
position with respect to the Security Deposit, and Landlord shall have the right
to refund all or any portion of the Security Deposit to the assignee at any time
or under any circumstances with no liability to the assignor.

     Landlord may require that the assignee or subtenant remit directly to 
Landlord on a monthly basis, all monies due to Tenant by said assignee or 
subtenant. In such event Landlord shall apply the sums received to the 
obligations of Tenant and its successors under this Lease.

     In the event of default by any assignee or subtenant or any successor of
Tenant in the performance of any of the terms hereof, Landlord may proceed
directly against Tenant without the necessity of exhausting remedies against
such assignee, subtenant or successor.

     Landlord may consent to subsequent assignments of the Lease or sublettings 
or amendments or modifications to the Lease with the assignee or other successor
of Tenant, and without obtaining Tenant's consent thereto, and any such actions 
shall not relieve Tenant of liability under this Lease.

     Consent by Landlord to one assignment or subletting shall not be deemed 
consent to any subsequent assignment or subletting.

     If Tenant is a corporation which, under California law, is not deemed a 
publicly-held corporation, or is an unincorporated association or partnership, 
the transfer, assignment or hypothecation of any stock or interest controlling  
such corporation, association or partnership shall be deemed an assignment 
within the meaning and provisions of this Section 17. For purposes hereof, 
"control" shall be deemed to refer to any amount, in the aggregate, exceeding 
25% of the voting power of such corporation, association or partnership. 
Notwithstanding the foregoing, the immediately preceding sentence shall not 
apply to any transfer of stock of Tenant if Tenant is a publicly-held 
corporation and such stock is transferred publicly over a recognized security 
exchange or over-the-counter market.

     Tenant agrees that all advertising by Tenant to market the space in the 
Premises to be sublet or assigned shall require Landlord's prior written 
approval, which shall not be unreasonably withheld. Tenant further agrees that 
it shall not, 

                                      16
<PAGE>
 
without Landlord's prior written consent, which may be granted or withheld in 
Landlord's sole discretion, market any space in the Premises, assign the lease 
or sublet any space in the Premises to existing tenants or occupants of the 
Building, or to any entity controlling, controlled by, or under common control 
with any existing tenant or occupant of the Building, except for any entity 
controlling, controlled by or under common control with Tenant.

     Tenant agrees that it shall not sublet, nor assign, nor advertise as 
available for subletting or assignment, nor list with brokers for subletting or 
assignment, all or any portion of the Premises for a consideration which is 
equal to less than the fair market rental value, as determined by Landlord in 
its reasonable discretion, for comparable space in the Building for a comparable
term commencing concurrently with the assignment or sublease term, with 
comparable rent credits and tenant improvement allowances. Within 10 days after 
Landlord receives any written request from Tenant for Landlord's estimate of the
fair market rental value for specified space (which request shall identify the 
space in question, the proposed term and the proposed rent credits and 
improvement allowances), Landlord shall notify Tenant in writing of the fair 
market rental value for such space for a comparable term with comparable rent 
credits and tenant improvement allowances.

     17.2  In the event that Tenant desires to assign this Lease, or to enter 
into a sublease, as to all or any portion of the Premises, except where the 
subtenant or assignee is an entity controlling, controlled by or under common 
control with Tenant, Tenant shall, prior to solicitation of offers therefor, 
give Landlord notice of Tenant's desire to assign or sublet and of the portion 
of the Premises to be affected by the proposed assignment or sublease. Landlord 
shall have the right, exercisable by notice to Tenant within 60 days after 
Landlord's receipt of Tenant's notice of desire to assign or sublet, to 
terminate this Lease as to the portion of the Premises affected by the proposed 
assignment or sublease, such termination to be effective as of the date 60 days 
after notice by Landlord to Tenant of such termination.

     In the event of a termination of this Lease as to a portion of the Premises
pursuant to this Section 17.2, effective as of such termination, the Premises 
shall be deemed to no longer include the portion of the Premises subject to such
termination, Tenant shall surrender possession of that portion of the Premises 
in accordance with the provisions of this Lease, and the rent payable hereunder 
and Tenant's Percentage Share shall be appropriately adjusted based upon the 
rentable area remaining within the Premises.

     If Landlord does not elect to terminate pursuant to this Section 17.2, and 
if Tenant does not enter into an assignment or sublease as specified in Tenant's
notice of desire to assign or sublet within 6 months after the expiration of 
Landlord's 60-day period for election to terminate, then Tenant shall again
comply with the provisions of this Section 17.2 before assigning this Lease, or
entering into a sublease, as to all or any portion of the Premises.

     17.3  In the event that Tenant has sought and received Landlord's consent 
to assign this Lease, or to enter into a sublease as to all or any portion of 
the Premises, the monthly rent payable by Tenant to Landlord, pursuant to 
Section 3, shall be increased by the amount to be received by Tenant during each
month pursuant to the terms of the assignment or sublease, in excess of Tenant's
monthly rental payable to Landlord for the space subject to the assignment or 
sublease. The amounts referred to in the previous sentence include rent, 
additional rent, or any other payment in respect of use or occupancy, or in 
reimbursement of costs of leasehold improvements installed by Tenant, and
whether paid in a lump sum or periodic payments. In no event shall the total
sums payable to the Landlord be less than the monthly rental Landlord would have
received but for such assignment or sublease.

     The additional rent shall be due and payable to Landlord in accordance with
the schedule specified in the sublease or assignment instrument, and the failure
of any subtenant or assignee to make any payments in accordance with that
schedule shall not affect the obligation of Tenant to pay the additional rent to
Landlord.

     The calculation of the amount of rentable space being sublet shall be made
by Landlord in accordance with its usual standards. Landlord may require 
acknowledgment by Tenant of Tenant's concurrence on the Landlord's calculation 
of the amount of rentable space being sublet as a condition to Landlord's 
consent to any sublease.

     The provisions of a sublease or assignment instrument consented to by 
Landlord cannot be modified, nor the sublease or assignment terminated, other 
than in accordance with its terms, without the prior written consent of the 
Landlord, which consent shall not be unreasonably withheld. The terms of this 
Section 17.3 shall apply to any subleasing or assignment by any subtenant or 
assignee.

     17.4  Tenant shall pay to Landlord, promptly upon receipt of a billing from
Landlord, the amount of Landlord's reasonable attorney fees incurred in 
connection with Landlord's review or approval of any sublease or assignment 
transaction requiring Landlord's consent hereunder.

                                      17
<PAGE>
 
     18.   TRANSFER OF LANDLORD'S INTEREST.  In the event of any transfer of 
Landlord's interest in the Building or Premises, other than a transfer for 
security purposes only, the transferor shall be automatically relieved of any 
and all obligations and liabilities on the part of Landlord accruing from and 
after the date of such transfer, including, without limitation, the obligation 
of Landlord to return the Security Deposit as provided in this Lease: provided 
that the transferor shall, within a reasonable time, transfer any Security 
Deposit then held by Landlord, or any portion thereof remaining after proper 
deductions therefrom, to the transferee and shall thereafter notify Tenant of 
such transfer, of any claims made against the Security Deposit, and of the 
transferee's name and address, by written notice delivered personally (in which 
case Tenant shall acknowledge receipt of such notice by signing Landlords's copy
of such notice) or by registered or certified mail.

     19.   HOLDING OVER.  If Tenant holds over after the term hereof, with or 
without the express or implied consent of Landlord, such tenancy shall be from 
month-to-month only, and shall not constitute a renewal hereof or an extension 
for any further term, and in such case, Base Rent shall be payable at a monthly 
rate equal to the greater of: (a) two hundred percent (200%) of the Base Rent 
applicable to the Premises immediately prior to the date of such expiration or 
earlier termination; or (b) one hundred fifty percent (150%) of the prevailing
market rate excluding any rental or other concessions (as reasonably determined 
by Landlord) for the Premises in effect on the date of such expiration or 
earlier termination.  Such month-to-month tenancy shall be subject to every 
other term, covenant and agreement contained herein.  Nothing contained in this
Section 19 shall be construed as consent by Landlord to any holding over by 
Tenant, and Landlord expressly reserves the right to require Tenant to surrender
possession of the Premises to Landlord as provided in this Lease upon the 
expiration or other termination of this Lease.

     20.   NOTICES.  In every case when, under the provisions of this Lease, it 
shall be necessary or desirable for one party hereto to serve any notice, 
request or demand on the other, such notice or demand shall be in writing and 
shall be served personally or by deposit in the United States mail, postage and 
fees fully prepaid, registered or certified mail, with return receipt requested,
addressed to the applicable address for notice set forth in Section A on page 1.
Landlord or Tenant may, from time to time, by notice in writing served upon the 
other as aforesaid, designate a different mailing address or a different 
person to whom all such notices or demands are thereafter to be addressed.  
Service of any such notice or demand if given personally shall be deemed 
complete upon delivery, and if made by mail shall be deemed complete on the day
of actual delivery as shown by the addressee's registry or certification receipt
or at the expiration of 2 business days after the date of mailing, whichever is 
earlier.

     Notwithstanding the provisions of this Section 20, any notice of default as
described in Section 13.2 and any pleadings or notices given by either party to 
the other with respect to any judicial proceeding between the parties shall be 
served in the manner prescribed by applicable California law without reference 
to this paragraph, and shall be deemed served at such time as is provided by 
such applicable law without reference to this paragraph.

     21.   QUIET ENJOYMENT.  Landlord covenants that Tenant, upon paying the 
rent and performing the covenants of this Lease on Tenant's part to be 
performed, shall and may peaceably and quietly have, hold and enjoy the Premises
for the term of this Lease.

     22.   TENANT'S FURTHER OBLIGATIONS.

     22.1  Except for ordinary wear and as otherwise provided in this Lease, 
Tenant shall, at Tenant's expense, keep in good order, condition and repair the 
interior of the Premises and shall promptly and adequately repair all damage to 
the interior of the Premises and replace or repair all glass, fixtures, 
equipment and appurtenances therein damaged or broken, under the supervision and
with the approval of Landlord and, if Tenant does not do so, Landlord may, but 
need not, make such repairs and replacements. If Landlord does so, Tenant shall
pay Landlord the cost thereof promptly upon demand, as additional rent
hereunder.

     22.2  Tenant shall comply with all laws, ordinances, rules, regulations, 
orders and directives of governmental and quasi-governmental bodies and 
authorities having jurisdiction over Tenant or the Premises from time to time 
and shall obtain and keep in effect all licenses, permits (including but not 
limited to conditional use permits) and other authorizations required with 
respect to the business or businesses conducted by Tenant within or from the 
Premises or with respect to any special equipment or facilities of Tenant 
permitted under the other provisions of this Lease.  Tenant and its employees, 
agents, licensees and invitees shall also comply with all reasonable rules and 
regulations which Landlord may adopt from time to time for the protection and 
welfare of the Building and its tenants and occupants; provided that Tenant 
shall not be responsible for compliance with any rule or regulation adopted by 
Landlord unless or until Tenant is furnished with a copy thereof.  The present 
rules and regulations for the Building are attached hereto as Exhibit "B".  
Landlord shall have no liability to Tenant for the failure of any other tenant 
in the Building to observe the rules and regulations.

                                      18
<PAGE>
 
     23.   ESTOPPEL CERTIFICATE BY TENANT.  At any time and from time to time,
within 15 days after written request by Landlord, Tenant shall execute,
acknowledge and deliver to Landlord a statement in writing certifying that this
Lease is unmodified and in full force and effect (or if there have been
modifications, that this Lease is in full force and effect as modified and
stating the modifications), that Tenant knows of no default hereunder by
Landlord and has no right of offset or deduction against the rent or any other 
charge payable to Landlord (or specifying any claimed), the amount of any 
security posted by Tenant, the dates to which the rent and other charges have 
been paid in advance, any increases or decreases of rent that are anticipated, 
the commencement date of the Lease and such other matters as may be reasonably 
requested by Landlord.  It is intended that any statement delivered pursuant to 
this Section 23 may be relied upon by any purchaser of the fee or mortgagee or 
beneficiary or assignee of any mortgage or trust deed upon the fee of the 
Building or Premises.  Tenant's failure to deliver the statement within the 
period specified above shall be conclusive and binding upon Tenant that the 
Lease is in full force and effect without modification except as may be 
represented by Landlord, that there are no uncured defaults in Landlord's 
performance and that Tenant has no right of offset, counterclaim or deduction 
against rental, and that no more than one month's rental has been paid in 
advance.

     24.   SUBORDINATION AND ATTORNMENT.  This Lease is and at all times shall
be subject and subordinate to any ground or underlying leases, mortgages, trust
deeds or like encumbrances, which may now or hereafter affect the Building or
Premises, and to all renewals, modifications, consolidations, replacements and
extensions of any such lease, mortgage, trust deed or like encumbrance.  As a
condition precedent to the effectiveness of any such subordination of this Lease
to any future ground or underlying leases or the lien of any future mortgages,
deeds of trust, or like encumbrances, Landlord shall provide to Tenant a
commercially reasonable non-disturbance and attornment agreement in favor of
Tenant executed by such future ground lessor, master lessor, mortgagee or deed
of trust beneficiary, as the case may be, which shall provide that Tenant's
quiet possession of the Premises shall not be disturbed on account of such
subordination to such future lease or lien so long as Tenant is not in default
under any provisions of this Lease. Notwithstanding the foregoing, Landlord
shall have the right to subordinate or cause to be subordinated any or all
ground or underlying leases or the lien of any or all mortgages, deeds of trust
or like encumbrances to the Lease. In the event that any ground or underlying
lease terminates for any reason or any mortgage, deed of trust or like
encumbrance is foreclosed or a conveyance in lieu of foreclosure is made for any
reason, then at the election of Landlord's successor-in-interest, Tenant shall
attorn to and become the tenant of such successor. Tenant hereby waives its
rights under any current or future law which gives or purports to give Tenant
any right to terminate or otherwise adversely affect this Lease and the
obligations of Tenant hereunder in the event of any such foreclosure proceeding
or sale. Tenant covenants and agrees to execute and deliver to Landlord in the
form reasonably required by Landlord, within 10 days after receipt of written
demand by Landlord, any additional documents evidencing the priority or
subordination of this Lease with respect to any ground or underlying lease or
the lien of any mortgage, deed of trust, or like encumbrance. Should Tenant fail
to sign and return any such documents within said 10-day period, Tenant shall be
in default hereunder without the benefit of any additional notice or cure
periods, except as may be required by statute.

     25.   RIGHTS RESERVED TO LANDLORD.

     25.1  All portions of the Building are reserved to Landlord, including 
exterior building walls, core corridor walls and doors and any core corridor 
entrance, but excluding the Premises and the inside surfaces of all walls, 
windows and doors bounding the Premises.  Landlord also reserves any space in or
adjacent to the Premises used for shafts, stacks, pipes, conduits, fan rooms, 
ducts, electric or other utilities, sinks or other building facilities, and the 
use thereof, as well as the right to access thereto through the Premises for the
purposes of operation, maintenance, decoration and repair.

     25.2  Landlord shall have the following rights exercisable without notice 
and without liability to Tenant for damage or injury to property, person or 
business (all claims for damage being hereby released), and without effecting an
eviction or disturbance of Tenant's use or possession or giving rise to any 
claim for setoffs or abatement of rent:

           (a)      To enter the Premises at all reasonable times during the 
term of this Lease for the purpose of inspecting the same, supplying janitorial 
service, posting notices of non-responsibility, exhibiting the Premises to 
prospective tenants, purchasers or others, or making such repairs or 
replacements therein as may be required by this Lease or as Landlord may deem 
appropriate; provided that Landlord shall use all reasonable efforts not to 
disturb Tenant's use and occupancy and shall, when practical, give Tenant prior 
notice of such repairs.  For each of the foregoing purposes, Tenant shall 
provide to Landlord a key with which to unlock at any time all of the doors in, 
upon and about the Premises, excluding Tenant's vaults and safes.  Landlord may 
use any other means which Landlord may deem  proper to open such doors in an 
emergency in order to obtain entry to the Premises.  Any entry to the Premises 
obtained by Landlord by any means shall not under any circumstances be construed
or deemed to be a forcible or unlawful entry into, or a detainer of, the 
Premises, or an eviction of Tenant from the Premises or any portion thereof, or 
grounds for any abatement or reduction of rent.  Any damages or losses on 
account of any such entry by Landlord shall be Tenant's sole responsibility 
except as otherwise

                                      19
<PAGE>
 
expressly provided herein. Nothing in this Section 25 shall be construed as 
obligating Landlord to perform any repairs, alterations or decorations, except 
as otherwise expressly required in this Lease.

           (b)  To change the name or street address of the Premises or
Building.

           (c)  To install and maintain signs on the exterior and interior of
the Building, except within the Premises.

           (d)  To have pass keys to the Premises.

           (e)  To decorate, remodel, repair, alter or otherwise prepare the 
Premises for reoccupancy during the last 6 months of the term hereof if, during 
or prior to such time, Tenant has vacated the Premises, or at any time after 
Tenant abandons the Premises.

           (f)  To have access to all mail chutes according to the rules of the 
United States Postal Service.

           (g)  To do or permit to be done any work in or about the exterior of 
the Building or any adjacent or nearby building, land, street or alley.

           (h)  To grant to anyone the exclusive right to conduct any business
or render any service in the Building, provided such exclusive right shall not
operate to exclude Tenant from the use expressly permitted by this Lease.

     26.   FORCE MAJEURE. Whenever there is provided in this Lease a time 
limitation for performance by Landlord or Tenant of any construction, repair, 
maintenance or service, the time provided for shall be extended for as long as 
and to the extent that delay in compliance with such limitation is due to an act
of God, governmental control or other factors beyond the reasonable control of 
Landlord or Tenant, respectively.

     27.   WAIVER OF CLAIMS; INDEMNITY.

     27.1  Tenant, as a material part of the consideration to Landlord, hereby 
assumes all risk of, and waives all claims it may have against Landlord, its 
agents, employees, affiliates and successors in interest for damage to or loss 
of property or personal injury or loss of life resulting from the Building or 
Premises or any part thereof becoming out of repair, by reason of any repair or 
alteration thereof, or resulting from any accident within the Building or 
Premises or on or about any space adjoining the Building or Premises, or 
resulting directly or indirectly from any act or omission of any person, or due 
to any condition, design or defect of the Building or Premises, or any space 
adjoining the Building or Premises, or the mechanical systems of the Building or
Premises, which may exist or occur, whether such damage, loss or injury results 
from conditions arising upon the Premises or upon other portions of the 
Building, or from other sources or places, and regardless of whether the cause 
of such damage, loss or injury or the means of repairing the same is accessible 
to Tenant; provided such assumption and waiver shall not apply to claims caused 
by the gross negligence or willful misconduct of Landlord or its agents.

     27.2  Tenant hereby indemnifies and holds Landlord and Landlord's agents, 
employees, affiliates and successors in interest harmless from and against any 
and all claims, demands, suits, fines, losses and other liabilities for or 
relating to injury or loss of life to persons or damage to or loss of property 
arising from Tenant's use of the Building or the Premises or from the conduct of
Tenant's business or from any work done, permitted or suffered by Tenant in or 
about the Premises or elsewhere, and further indemnifies and holds Landlord and 
Landlord's agents, employees, affiliates and successors in interest harmless 
from and against any and all claims arising from any breach or default in the
performance of any obligation on Tenant's part to be performed under the terms
of this Lease, or arising from any negligence or intentional conduct of Tenant
or Tenant's agents, employees, contractors, licensees, invitees, representatives
or successors in interest, and from and against all costs, attorneys' and other
professional fees, expenses and liabilities incurred by Landlord or Landlord's
agents, employees, affiliates and successors in interest in or in connection
with any such claim, demand, suit, fine or proceeding. In the event that any
action or proceeding be brought against Landlord or Landlord's agents,
employees, affiliates or successors in interest by reason of any such claim,
Tenant upon notice from Landlord shall defend such action or proceeding at
Tenant's cost and expense by counsel approved by Landlord, such approval not to
be unreasonably withheld.

     28.   INSURANCE.

     28.1  Tenant shall procure and shall maintain in effect, at Tenant's sole 
cost and expense throughout the term of this Lease, including any extensions and
renewals thereof, public liability and property damage insurance against claims 
for bodily injury, death or property damage occuring upon or about the Premises 
or Building, in each case naming Landlord as additional insured and, upon 
request by Landlord, naming the holder of any mortgage, deed of trust or like 
encumbrance or the lessor under any underlying lease covering the Building as 
additional insured, with a limit of liability of (a) not less than $1,000,000.00
single limit during the initial three-year period of the Lease term from the 
Commencement Date to the third anniversary of the Lease term; and (b) not less 
than $2,000,000.00 single limit during the balance of the Lease term from the 
day after the third anniversary of the Lease term to the end of the Lease term. 
If from time to time, the limits of liability set forth in Subsection 28.1(b) 
above are, in the reasonable opinion of Landlord, inadequate, Tenant shall 
increase such insurance coverage to an amount as shall be designated by 
Landlord's notice to Tenant.

     Tenant shall also procure and maintain, at Tenant's sole cost and expense 
throughout the term of this Lease, casualty insurance on Tenant's personal 
property in the Premises and any leasehold improvements which the Tenant 
installed at its own cost in an amount at least equal to the full replacement 
cost of such property, providing coverage against all perils insured against by 
a "fire and extended coverage" policy, as well as sprinkler damage, vandalism 
and malicious mischief.

     Tenant shall also obtain the following insurance:

           (a)   Worker's compensation and employer's liability insurance in
form and amount satisfactory to Landlord.

           (b)   Loss of income and extra expense insurance in such amounts as 
will reimburse Tenant for direct or indirect loss of earnings attributable to 
all perils commonly insured against by prudent tenants or attributable to
prevention of access to or use of the Premises or the Building as a result of
such perils.

           (c)   Liquor liability insurance coverage in limits of not less than 
Five Hundred Thousand Dollars ($500,000) if at any time during the term hereof 
any alcoholic beverages of any nature are served on the Premises.

           (d)   Any other form or forms of insurance as Landlord or Landlord's 
lender or ground or primary lessors may reasonably require from time to time in 
form, in amounts, and for insurance risks against which a prudent tenant of a 
comparable size and in a comparable business would protect itself.

     Such policies of insurance shall be with insurance companies acceptable to 
Landlord, shall not have a deductible amount exceeding $5,000.00 in the 
aggregate, and shall specifically provide that the insurance afforded by such 
policies for the benefit of Landlord and Landlord's mortgagees and ground 
lessors shall be primary, and that any insurance carried by Landlord or 
Landlord's, mortgagees and ground lessors shall be excess and non-contributing. 
Such policies shall be evidenced by certificates of insurance delivered to
Landlord from time to time showing such insurance to be at all times prepaid and
in full force and effect and providing that such insurance cannot be cancelled
or modified upon less than 30 days' prior written notice to Landlord. If at any
time Tenant has not provided Landlord with a then currently effective
certificate of insurance acceptable to Landlord as to any insurance required to
be maintained by Tenant, Landlord may, without further inquiry as to whether
such insurance is actually in force, obtain such a policy and Tenant shall
reimburse Landlord, upon demand as additional rent hereunder, for the cost
thereof, together with Landlord's administrative fee equal to 25% of the
premium.

     28.2  Tenant hereby waives its rights against Landlord and its managing 
agent and their respective partners, officers, directors, shareholders, 
employees, agents, representatives, contractors, affiliates, successors, 
licensees, and invitees with respect to any claims or damages or losses 
(including any claims for bodily injury to persons and/or damage to property)
which are caused by or result from (a) risks insured against under any insurance
policy carried by Tenant at the time of such claim, damage, loss or injury, or
(b) risks which would have been covered under any insurance required to be
obtained and maintained by Tenant under this Lease had such insurance been
obtained and maintained as required. The foregoing waivers shall be in addition
to, and not a limitation of, any other waivers or releases contained in this
Lease.

     28.3  Tenant shall cause each insurance policy required to be obtained by 
it pursuant to this Section 28 to provide that the insurer waives all rights of 
recovery by way of subrogation against Landlord and its managing agent and their
respective partners, officers, directors, shareholders, employees, agents, 
representatives, contractors, affiliates, successors, licensees, and invitees in
connection with any claims, losses and damages covered by such policy. If Tenant

                                      21
<PAGE>
 
fails to maintain insurance required hereunder, Tenant shall be deemed to be
self-insured with a deemed full waiver of subrogation as set forth in the
immediately preceding sentence.

     29.   FIXTURES, TENANT IMPROVEMENTS AND ALTERATIONS.

     29.1  Except as otherwise provided in any rider to this Lease, all
improvements, fixtures and/or equipment which Tenant may install or place in or
about the Premises, and all alterations, repairs or changes to the Premises, and
all signs installed in, on or about the Premises, from time to time shall be at
the sole cost of Tenant. Landlord shall be without any obligation in connection
therewith. Tenant hereby indemnifies and holds Landlord harmless from any
liability, cost, obligation, expense or claim of lien in any manner relating to
the installation, placement, removal or financing of any such alterations,
repairs, changes, improvements, fixtures and/or equipment in, on or about the
Premises.

     29.2  Nothwithstanding any provision in this Section 29 to the contrary,
Tenant is absolutely prohibited from making any alterations, additions,
improvements or decorations which: (i) affect any area outside the Premises;
(ii) affect the Building's structure, equipment, services or systems, or the
proper functioning thereof, or Landlord's access thereto; (iii) affect the
outside appearance, character or use of the Building or the common areas; (iv)
weaken or impair the structural strength of the Building; (v) in the opinion of
Landlord, lessen the value of the Building; (vi) will violate or require a
change in any occupancy certificate applicable to the Premises; or (vii) in the
opinion of Landlord, will increase the Building's Operating Costs or Utility
Costs.

     29.3  Before proceeding with any alteration, repair or change which is not 
otherwise prohibited in Subsection 29.2 above, Tenant must first obtain 
Landlord's written approval of(i) the plans and specifications for all such 
work; (ii) with respect to any connecting lines that will be outside the 
Premises (if such lines are permitted by Landlord in its sole discretion), a 
description of the areas of the Building to which Tenant will require access 
both for the initial work and for ongoing maintenance of the improvements or 
installations; (iii) the names of all contractors and subcontractors who will 
perform such work, all of whom shall be selected from Landlord's then-current 
list of approved contractors, which Landlord may compile in Landlord's sole 
discretion and will provide to Tenant within ten days following Landlord's 
receipt of Tenant's written request; (iv) copies of all liability, casualty and 
worker's compensation insurance applicable to the construction, maintenance and 
ongoing operation of the improvements and installations; and (v) copies of all 
governmental permits required for the work. Landlord's consent to such matters 
shall not unreasonably be withheld; provided, however, that with regard to any 
such matters which may affect the structural members, the heating, ventilation, 
air conditioning or other building systems, exterior walls, windows and doors of
the Building, and with regard to the installation of any signs outside the 
Premises, Landlord may grant or withhold its consent in its unlimited 
discretion. Landlord may impose, as a condition of its consent to any
alterations, repairs or changes of the Premises, such requirements as Landlord
in its sole discretion may deem desirable, including, but not limited to, the
requirement that Tenant utilize for such purposes only contractors, materials,
mechanics and materialmen previously used and currently approved by Landlord for
work in the Building.

     29.4  After Landlord has approved the change, repair or alteration and the
other items listed in Section 29.3, Tenants shall enter into an agreement for
the performance of such change, repair or alteration with the contractors and
subcontractors approved by Landlord, as provided in Section 29.3. Before
proceeding with any change, repair or alteration Tenant shall (i) provide
Landlord with 10 days' prior written notice thereof; and (ii) pay to Landlord,
within 10 days after written demand, the costs of any increased insurance
premiums incurred by Landlord as a result of such changes, repairs or
alterations. In additions, before proceeding with any change, repair or
alteration, Tenant's contractors shall obtain, on behalf of Tenant and at
Tenant's sole cost and expense: (A) all necessary governmental permits and
approvals for the commencement and completion of such change, repair or
alteration; and (B) a completion and lien indemnity bond, or other surety,
satisfactory to Landlord for such change, repair or alteration. Landlord's
approval of permits pursuant to Section 29.3 shall not relieve Tenant of the
obligation to obtain any other or supplemental permits required by the preceding
sentence.

     29.5  Tenant shall pay to Landlord, as additional rent, the reasonable
costs of Landlord's engineers and other consultants (but not Landlord's on-site
management personnel) for review of all plans, specifications and working
drawings for the change, repair or alteration within 10 business days after
Tenant's receipt of invoices either from Landlord or such consultants. In
addition to such costs, Tenant shall pay to Landlord, within 10 business days
after completion of any change, repair or alteration, the actual, reasonable
costs incurred by Landlord for services rendered by Landlord's management
personnel and engineers to coordinate and/or supervise any of the change, repair
or alteration to the extent such services are provided in excess of or after the
normal on-site hours of such engineers and management personnel.

     29.6  All changes, repairs and alterations shall be performed: (i) in
accordance with the approved plans, specifications and working drawings; (ii)
lien-fee and in a fist-class and workmanlike manner; (iii) in compliance with
all laws, rules, and regulations of all governmental agencies and authorities;
(iv) in such a manner so as to not interfere with

                                      22

<PAGE>
 
the occupancy of any other tenant in the Building, nor impose any additional 
expense or delay upon Landlord in the maintenance and operation of the Building;
and (v) at such times, in such manner and subject to rules and regulations as 
Landlord may from time to time reasonably designate.

     29.7 Throughout the performance of any such change, repair or alteration 
Tenant shall obtain, or cause its contractors to obtain, worker's compensation 
insurance and general liability insurance covering the work in compliance with 
provisions of Section 28 of this Lease, and builder's risk insurance for the 
work reasonably acceptable to Landlord.

     29.8 In the event Tenant orders any construction, alteration, decorating or
repair work directly from Landlord, or from the contractor selected by Landlord,
the charges for such work, together with Landlord's administration fee equal to 
15% of the contract price, shall be deemed additional rent under this Lease, 
payable upon billing therefor, either in advance of the start of work, or 
periodically during construction, or upon the substantial completion of such 
work, at Landlord's option.

     30.  MECHANIC'S LIENS.   Tenant agrees to give Landlord written notice of 
the commencement date of any alterations, improvements or repairs to be made in,
to or upon the Premises not later than 15 days prior to the commencement of any 
such work, in order to give Landlord time to post notices of nonresponsibility. 
Tenant will not permit any mechanic's, materialman's or other lien to be placed 
upon the Premises or Building or improvements therein during the term thereof; 
and in the event that any mechanic's materialman's or other lien is filed 
against the Premises or Building or improvements therein in connection with any 
alteration, repair, improvement or change of, or installation of fixtures or 
equipment in, the Premises, Tenant shall cause such lien to be released within 
10 days after such filing, either by satisfaction of such claim or by posting of
a bond. Notwithstanding the foregoing, Landlord shall have the right and 
privilege at Landlord's option of paying the amount of any such lien or claim, 
or any portion thereof, without inquiry as to the validity thereof, and any 
amounts so paid, including expenses and interest, shall be deemed additional 
rent hereunder due from Tenant to Landlord upon demand.

     31.  ALTERNATE SPACE.    If the Premises comprise less than a full floor 
in the Building, Landlord shall have the privilege of moving Tenant to other 
space in the Building comparable to the Premises, and all terms hereof shall 
apply to the new space with equal force. In such event Landlord shall give 
Tenant at least 60 days' prior notice in writing and shall move Tenant's effects
to the new space at Landlord's sole cost and expense at such time and in such 
manner as to inconvenience Tenant as little as practicable.

     32.  HAZARDOUS MATERIALS.

     32.1 In addition to its other obligations under this Lease, Tenant 
covenants to comply with all laws relating to Hazardous Materials, as defined 
below, with respect to the Premises and the Building. Except for general office 
supplies typically used in an office area in the ordinary course of business 
(such as copier toner, liquid paper, glue, ink and cleaning solvents), for use 
in the manner for which they were designed and only in accordance with all 
Hazardous Materials laws and the highest standards prevailing in the industry 
for such use, and then only in such amounts as may be normal for the office 
business operations conducted by Tenant on the Premises, neither Tenant nor any 
of Tenant's agents, employees, contractors, subtenants, assignees, licensees or 
invitees ("Tenant's Parties") shall use, handle store or dispose of any 
Hazardous Materials in, on, under or about the Premises, the Building or the 
site on which the Building is located. Tenant shall promptly take all actions, 
as its sole cost and expense, as are necessary to return the Premises, Building 
and site to the condition existing prior to the introduction of any such 
Hazardous Materials by Tenant or any Tenant Parties, provided Landlord's 
approval of such actions shall first be obtained. Furthermore, Tenant shall 
immediately notify Landlord of any inquiry, test, investigation or enforcement 
proceeding by or against Tenant or the Premises concerning the presence of any 
Hazardous Material.

     32.2 Tenant shall be solely responsible for and shall indemnify, defend 
(with counsel reasonably approved by Landlord) and hold Landlord harmless from 
and against any and all claims, demands, judgments, suits, causes of action, 
damages, penalties, fines, liabilities, losses and expenses (including, without 
limitation, investigation and clean-up costs, attorneys' fees, consultant fees 
and court costs) which arise during or after the term of this Lease as a result 
of the breach of any of the obligations and covenants set forth in this Section 
33, and/or any contamination of the Premises, Building or site directly or 
indirectly arising from the activities of Tenant or any Tenant Parties.

     32.3 For purposes of this Lease, the term "Hazardous Materials" shall mean,
collectively, asbestos, any petroleum fuel, and any hazardous or toxic 
substance, material or waste which is or becomes regulated or defined as 
hazardous or toxic by any local governmental authority, the State of California 
or the United States Government, including, but not limited to, any material or 
substance defined as hazardous or toxic under the Comprehensive Environmental 
Response, Compensation and Liability Act, 42 U.S.C. (S) 9601, et seq.; the

time to time.

     32.4  The foregoing covenants and indemnities of Tenant shall survive the 
expiration or earlier termination of the Lease.

     33.   MISCELLANEOUS.

     33.1  No receipt of money by Landlord from Tenant after the termination of
this Lease, the service of any notice, the commencement of any suit or final
judgement for possession shall reinstate, continue or extend the term of this
Lease or affect any such notice, demand, suit or judgment. No payment by Tenant
or receipt by Landlord of a lesser amount than the rent payment herein
stipulated shall be deemed to be other than on account of the rent, nor shall
any endorsement or statement on any check or any letter accompanying any check
or payment as rent be deemed an accord and satisfaction, and Landlord may accept
such check or payment without prejudice to Landlord's right to recover the
balance of such rent or pursue any other remedy provided in this Lease. Tenant
agrees that each of the foregoing covenants and agreements shall be applicable
to all obligations of Tenant to Landlord, whether expressly contained in this
Lease or imposed by any statute or at common law.

     33.2  If any provision of this Lease or its application to any party or 
circumstances shall be determined by any court of competent jurisdiction to be 
invalid or unenforceable to any extent, the remainder of this Lease or the 
application of such provision to such person or circumstances, other than those 
as to which it is so determined invalid or unenforceable to any extent, shall 
not be affected thereby, and each provision hereof shall be valid and shall be 
enforced to the fullest extent permitted by law; and it is the intention of the 
parties to this Lease that in lieu of each clause or provision of this Lease 
that is illegal, invalid or unenforceable, there be added as a part of this 
Lease a clause or provision as similar in terms to such illegal, invalid or 
unenforceable clause or provision as may be possible and be legal, valid and 
enforceable.

     33.3  The covenants and obligations of Tenant pursuant to this Lease shall
be independent of performance by Landlord of the covenants and obligations of
Landlord pursuant to this Lease, and performance by Tenant of each covenant and
obligation of Tenant pursuant to this Lease shall be a condition precedent to
the duty of Landlord to perform the covenants and obligations of Landlord
pursuant to this Lease.

     33.4 The headings of Sections of this Lease are of convenience only and do
not define, limit or construe the contents thereof. References made in this
Lease to numbered Sections, Paragraphs and Subparagraphs shall refer to numbered
Sections, Paragraphs or Subparagraphs of this Lease unless otherwise indicated.

     33.5 Where appropriate, words in the singular, including without limitation
the words "Landlord" and Tenant", include the plural, and vice versa. Words in
the neuter gender include the masculine and feminine genders, and vice versa,
and words in the masculine gender include the feminine gender, and vice versa.

     33.6  If more than one person or entity executes this Lease as Tenant: (a)
each of them is and shall be jointly and severally liable for the covenants,
conditions, provisions and agreements of this Lease to be kept, observed and
performed by Tenant; and (b) the act or signature of, or notice from or to, any
one or more of them with respect to this Lease shall be binding upon each and
all of the persons and entities executing this Lease as Tenant with the same
force and effect as if each and all of them had so acted or signed, or given or
received such notice.

     33.7  Time is of the essence of this Lease. Failure of either party to
perform any act strictly within the applicable period specified herein shall
entitle the other to exercise all remedies herein contemplated. All references
in this Lease to "days" shall mean calendar days unless specifically stated
herein to be "business" days.

     33.8  This Lease shall be governed by and interpreted in accordance with
the laws of the State of California.

                                      24
<PAGE>
 
     33.9   All monetary obligations of either party hereunder to the other 
remaining past due 10 days or more after the date specified herein for payment 
shall bear interest until paid at the lesser of (i) the Bank of America prime 
rate as of the due date plus 6%, or (ii) the maximum rate permitted by law.

     33.10  This instrument, along with any riders, exhibits and attachments or 
other documents referred to in Section M on page 2 (all of which riders, 
exhibits, attachments and other documents are hereby incorporated into this 
instrument by this reference), constitutes the entire and exclusive agreement 
between Landlord and Tenant relating to the Premises, and this agreement and 
said riders, exhibits and attachments and other documents may be altered, 
amended or revoked only by an instrument in writing signed by the party to be 
charged thereby. All prior or contemporaneous oral agreements, understandings 
and/or practices relative to the leasing of the Premises are merged herein or 
revoked hereby. References in this instrument to this "Lease" shall mean, refer 
to and include this instrument as well as any riders, exhibits, attachments or 
other documents referred to in Section M, and references to any covenant, 
condition, obligation and/or undertaking "herein", "hereunder" or "pursuant
hereto" (or language of like import) shall mean, refer to and include the
covenants, conditions, obligations and undertakings existing pursuant to this
instrument and such riders, exhibits, attachments or other documents. All terms
defined in this instrument shall be deemed to have the same meanings in all
riders, exhibits, attachments or other documents referred to in Section M unless
the context thereof clearly requires the contrary.

     33.11  Tenant hereby consents to amendment of this Lease as and to the 
extent required by any lender which makes a loan to Landlord secured in whole or
in part by the Building, provided that no such change shall increase the rent 
payable hereunder or impair Tenant's use of the Premises.

     33.12  Unless otherwise agreed in writing, if Tenant has dealt with any 
real estate broker or other person or firm with respect to leasing or renting 
space in the Building, Tenant shall be solely responsible for the payment of any
fee due said broker, person or firm and Tenant hereby indemnifies and holds 
Landlord harmless from and against any liability with respect thereto. 
Notwithstanding the foregoing, Landlord agrees to pay, and to hold Tenant 
harmless from, the commission owing to the brokers identified in Section L on 
page 2, as provided in a separate agreement between Landlord and such brokers.

     33.13  Tenant agrees to pay to Landlord as additional rent hereunder any 
taxes required by law to be paid by Tenant and collected from Tenant by 
Landlord.

     33.14  Submission of this Lease for examination, even though executed by 
Tenant, shall not bind Landlord in any manner, and no lease or other obligation 
on the part of Landlord shall arise until this Lease is executed and delivered 
by Landlord to Tenant. This Lease shall not be binding and in effect until a 
counterpart hereof has been executed and delivered by the parties, each to the 
other.

     33.15  Tenant shall not cause the recordation of this Lease, a short form 
memorandum of this Lease or any reference to this Lease.

     33.16  Upon 10 days' prior written request from Landlord (which Landlord 
may make at any time during the term but no more than two times in any calendar 
year), Tenant shall deliver to Landlord (a) a current financial statement of 
Tenant and any guarantor of this Lease, and (b) financial statements of Tenant 
and such guarantor for the two years prior to the current financial statement 
year. Such statements shall be prepared in accordance with generally acceptable 
accounting principles, and certified as true in all material respects by Tenant 
(if Tenant is an individual) or by an authorized officer or general partner of 
Tenant (if Tenant is a corporation or partnership, respectively).

     33.17  Notwithstanding anything contained in this Lease to the contrary, 
the obligations of Landlord under this Lease (including any actual or alleged 
breach or default of Landlord) do not constitute personal obligations of the 
individual partners, directors, officers, shareholders, agents or employees of 
Landlord or of Landlord's partners or agents, and Tenant shall not seek recourse
against any such persons or entities or any of their personal assets for 
satisfaction of any liability with respect to this Lease. In addition, in 
consideration of the benefits accruing hereunder to Tenant and notwithstanding 
anything contained in this Lease to the contrary, Tenant hereby covenants and 
agrees for itself and all of its successors and assigns that the liability of 
Landlord for its obligations under this Lease (including any liability as a 
result of any actual or alleged failure, breach or default hereunder by 
Landlord) shall be limited solely to, and Tenant's and its successors' and 
assigns' sole and exclusive remedy shall be against, Landlord's interest in the 
Building and proceeds therefrom, and no other assets of Landlord.

     33.18  If Tenant is identified herein as a corporation, then the persons 
executing this Lease on behalf of Tenant hereby represent that they are duly 
authorized to execute and deliver this Lease on behalf of Tenant pursuant to 
Tenant's by-laws or a resolution of its board of directors.

                                      25
<PAGE>
 
     If Tenant is identified herein as a partnership, the undersigned represent 
that they are all of the general partners of Tenant, that Tenant has been formed
under the laws of the State of California, and is duly qualified to do business 
in the State of California, and that this Lease is being executed on behalf of 
Tenant. Each of the partners of Tenant executing this Lease agrees that he or 
she and Tenant are irrevocably bound by execution of any amendment to or 
modification of this Lease by one or more of the partners of Tenant. Tenant 
agrees that each new partner in Tenant shall be obligated under this Lease, in 
the same fashion as the existing partners, and that each new partner shall 
execute a copy of this Lease and deliver it to Landlord within 60 days after 
that partner's admission to the partnership. In the event that such newly 
admitted partner is a corporation, the principal or principals for whose benefit
the corporation has been organized shall execute and deliver to Landlord a lease
guaranty in form acceptable to Landlord. Each newly admitted partner in Tenant 
shall be jointly and severally liable with the remaining partners for the 
performance and satisfaction of all obligations of the Tenant under this Lease 
accruing from and after the effective date of the admission of the new partner 
to the Partnership. If the provisions of this paragraph are satisfied, the

control and prevent access thereto of all persons whose presence in the judgment
of Landlord would be prejudicial to the safety, character, reputation and

persons are engaged in illegal activities.

     2.   Tenant shall not commit any act or permit any thing in or about the 
Building which shall or might subject Landlord to any liability or 
responsibility for injury to any person or property by reason of any business or

operate upon the Premises any vending machine without the consent of Landlord.

     10.  Tenant shall move all freight, supplies, furniture, fixtures and other
personal property into, within and out of the Building only at such times and 
through such entrances as may be designated by Landlord, and such movement of 
such items shall be under the supervision of Landlord. Landlord reserves the 
right to inspect all such freight, supplies, furniture, fixtures and other 
personal property to be brought into the Building and to exclude from the 
Building all such objects which violate any of these rules and regulations or 
the provisions of the Lease. Tenant shall not move or install such objects in or
about the Building in such a fashion as to unreasonably obstruct the activities 
of other tenants, and all such moving shall be at the sole expense, risk and 
responsibility of Tenant. Prior to permitting access into the Building of the 
moving company or other persons performing such moving activities, Landlord may 
require from such moving company or other persons evidence of insurance 
reasonably acceptable to Landlord, from an insurer and with coverage and amounts
reasonably acceptable to Landlord, covering the moving activities and naming 
Landlord and its managing agent as additional insureds. Tenant shall not use in

be designated by Landlord.

     11.  Tenant shall not place a load upon any floor of the Premises which 
exceeds the load per square foot which such floor was designed to carry and 
which is allowed by law. Landlord shall have the right to prescribe the weight, 
size and position of all equipment, materials, furniture or other property 
brought into the Building. Heavy objects, if such objects are considered 
necessary by Tenant, and are permitted by Landlord, shall stand on such 
platforms as determined by Landlord to be necessary to properly distribute the 
weight. Business machines and mechanical equipment belonging to Tenant, which 
cause noise or vibration that may be transmitted to the structure of the 
Building or to any space therein to such a degree as to be objectionable to 
Landlord or to any tenants in the Building, shall be placed and maintained by 
Tenant, at Tenant's expense, on vibration eliminators or other devices 
sufficient to eliminate noise or vibration. The persons employed to move such 
equipment in or out of the Building must be acceptable to Landlord. Landlord 
will not be responsible for loss of, or damage to, any such equipment or other 
property from any cause, and all damage done to the Building by maintaining or 
moving such equipment or other property shall be repaired at the expense of 
Tenant.

     12.  Tenant shall not deposit any trash, refuse, cigarettes, or other

right to control or prevent access thereto by all persons whose presence, in the
judgment of Landlord, shall be prejudicial to the safety, character, reputation 
or interests of the Building and its tenants. Neither Tenant nor any employee or
invitee of Tenant shall enter the mechanical rooms, air conditioning rooms, 
electrical closets, janitorial closets, or similar areas or go upon the roof of 
the Building without the express prior written consent of Landlord.

     14.  Landlord reserves the right to exclude or expel from the Building any 
person who, in the judgment of Landlord, is intoxicated or under the influence 
of liquor or drugs or who shall in any manner act in violation of the rules and 
regulations of the Building.

of the Building, and appurtenances thereto, for any other purpose than the
purpose for which they were constructed, and Tenant shall not deposit any

waste water by interfering or tampering with the faucets or otherwise. If Tenant
or Tenant's servants, employees, contractors, jobbers, agents, licensees,

plumbing fixtures or appurtenances, such damage shall be repaired at Tenant's
expense, and Landlord shall not be responsible therefor.

All cleaning and janitorial services for the Building and the Premises shall be
provided exclusively through Landlord, and except with the written consent of
Landlord, no person or persons other than those approved by Landlord shall be
employed by Tenant or permitted to enter the Building for the purpose of
cleaning the same. Tenant shall not cause any unnecessary labor by carelessness
or indifference to the good order and cleanliness of the Premises. Landlord
shall not in any way be responsible to Tenant for any loss of property on the
Premises, however occurring, or for any damage to any Tenant's property by the
janitor or any other employee or any other person. Without limitation upon any
of the provisions of the Lease, Tenant shall refer all contractors'
representatives, installation technicians, janitorial workers and other
mechanics, artisans and laborers rendering any service in connection with the
repair, maintenance or improvement of the Premises to Landlord for Landlord's
supervision, approval and control before performance of any such service. This
Paragraph 17 shall apply to all work performed in the Building, including
without limitation installation of telephones, telegraph equipment, electrical
devices and attachments and installations of any nature affecting floors, walls,

and other office equipment affixed to the Premises shall be subject to the
express prior written approval of Landlord. Tenant shall not lay linoleum or
similar floor coverings so that the same shall come into direct contact with the

deadening felt shall be first affixed to the floor, by a paste or other material
soluble in water. The use of cement or other similar adhesive material is
expressly prohibited.

     18.   No signs, awnings, showcases, advertising devices or other

drapes or other window coverings shall be installed in the Building without the 
express prior written consent of Landlord. No sign, picture, advertisement,

the express prior written consent of Landlord. In the event of the violation of 
any of the foregoing by Tenant, Landlord may remove the articles constituting 
the violation without any liability and Tenant shall reimburse Landlord for the 
expense incurred in such removal upon demand as additional rent under the Lease.
Interior signs on doors and upon the Building directory shall be subject to the 
express prior written approval of Landlord and shall be inscribed, painted, or

Landlord's express prior written consent, except for the purpose of identifying 
Tenant's address.

     20.   Tenant shall be entitled to have its name entered upon the directory 
of the Building. In the event that Tenant wishes to have additional entries made
upon the Building directory for the names of employees of Tenant who occupy 
office space within the Premises, such entries may be allowed by Landlord in its
reasonable discretion, and Landlord may require that Tenant pay a reasonable fee
for each such additional entry. However, the directory of the Building is 
provided primarily for the display of the name and location of tenants only, and
Landlord reserves the right to exclude any other names therefrom at any time. 
All entries upon the Building directory shall be in uniform print of a size, 
style and format selected by Landlord.

     21.  The sashes, sash doors, skylights, windows and doors that reflect or
admit light or air into the Common Areas shall not be covered or obstructed by 
Tenant, through placement of objects upon window sills or otherwise. Tenant 
shall cooperate with Landlord in obtaining maximum effectiveness of the cooling 
and heating systems of the Building by keeping corridor doors closed and by 
closing drapes and other window coverings when the sun's rays fall upon windows
of the Premises and at the end of the business day. Tenant shall not obstruct,
alter or in any way impair the efficient operation of Landlord's heating,
ventilating, air conditioning, electrical, fire, safety or lighting systems, nor
shall Tenant tamper with or change the setting of any thermostat or temperature
control valves in the Building. Tenant shall not waste electricity, water or air
conditioning and agrees to cooperate fully with Landlord to assure the most
effective operation of the Building's heating and air conditioning and to comply
with any governmental energy-saving rules, laws or regulations of which Tenant
has actual notice.

     22.  Subject to applicable fire or other safety regulations, all doors 
opening onto Common Areas and all doors upon the perimeter of the Premises shall
be kept closed and, during non-business hours, locked, except when in use for 
ingress or egress. If Tenant uses the Premises after regular business hours or 
on non-business days Tenant shall lock any entrance doors to the Building or to 
the Premises used by Tenant immediately after using such doors.

     23.  The requirements of Tenant will be attended to only upon appropriate 
application to the office of the Building by an authorized individual. Tenant

outside of their regular duties unless under special instructions from Landlord 
or the project manager for the Building. Tenant shall not request any employee 
of Landlord to admit any person (Tenant or otherwise) to any office without 
specific instructions from Landlord or the project manager for the Building. 
Employees of Landlord shall not receive or carry messages for or to Tenant or 
any other person, nor contract with nor render free or paid services to Tenant 
or Tenant's servants, employees, contractors, jobbers, agents, invitees, 
licensees, guests or visitors. In the event that any of Landlord's employees 
perform any such services, such employees shall be deemed to be the agents of 
Tenant regardless of whether or how payment is arranged for such services, and 
Tenant hereby indemnifies and holds Landlord harmless from any and all 
liability in connection with any such services and any associated injury or 
damage to property or injury or death to persons resulting therefrom.

     24.  All keys to the exterior doors of the Premises shall be obtained by 
Tenant from Landlord, and Tenant shall pay to Landlord a reasonable deposit 
determined by Landlord from time to time for such keys. Landlord will furnish 
Tenant, free of charge except for the deposit, with two keys to each door lock 
in the Premises. Landlord may make a reasonable charge for any additional keys. 
Tenant shall not make or have made duplicate copies of such keys. Tenant shall 
not install additional locks or bolts of any kind upon any of the doors or 
windows of, or within, the Building, nor shall Tenant make any changes in 
existing locks or the mechanisms thereof. Tenant shall, upon the termination of 
its tenancy, provide Landlord with the combination locks on safes, safe cabinets
and vaults and deliver to Landlord all keys to the Building, the Premises and 
all interior doors, cabinets, and other key-controlled mechanisms therein, 
whether or not such keys were furnished to Tenant by Landlord. In the event of 
the loss of any key furnished to Tenant by Landlord, Tenant shall pay to 
Landlord the cost of replacing the same or of changing the lock or locks opened
by such lost key if Landlord shall deem it necessary to make such a change.

     25.  Access may be had by Tenant to the Common Areas and to the Premises at
any time between the hours of 8:00 A.M. and 6:00 P.M., Monday through Friday, 
legal holidays excepted. At other times access to the Building may be refused 
unless the person seeking admission is known to the watchman in charge, if any, 
and/or has a pass or is properly identified. Tenant shall be responsible for all
persons for whom Tenant requests passes, and shall be liable to Landlord for all
acts of such persons. In the event Building has, or there is subsequently, a 
card access system for using the elevators at other than normal operating hours 
for the Building, Landlord may deny access to any area served by the elevators 
by anyone not having the necessary elevator access card. Landlord shall in no 
case be liable for damages for the admission or exclusion of any person from the
Building. In case of invasion, mob, riot, public excitement, or other commotion,
Landlord reserves the right to prevent access to the Building for the safety of 
tenants and protection of property in the Building.

     26.  Landlord shall not be responsible for, and Tenant hereby indemnifies 
and holds Landlord harmless from any liability in connection with, the loss, 
theft, misappropriation or other disappearance of furniture, furnishings, 
fixtures, machinery, equipment, money, jewelry or other items of personal 
property from the Premises or other parts of the Building, regardless of whether
the Premises or Building are locked at the time of such loss.

     27.  Tenant shall not use or permit to be used in the Premises any foul or 
noxious gas or substance, or permit or allow the Premises to be occupied or  
used in a manner offensive or objectionable to Landlord or other occupants of

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

     Provided Tenant is not in default under this Lease and pays the applicable 
prevailing monthly parking rate in effect from time to time, and subject to such
rules and regulations as may be adopted from time to time by Landlord or the 
operator of the parking facility serving the Building, Tenant and Tenant's 
authorized employees designated by Tenant ("Authorized Users") shall have the 
right to use in such parking facility up to the full Tenant's Parking Allotment 
described in Paragraph K on page 2 of this Lease, on an unreserved monthly basis
until the expiration or termination of this Lease. However, if at any time 
during the term of this Lease, Tenant does not choose to pay for the full number
of such parking spaces, Tenant shall not thereafter have the right to recommence
the use of the spaces not paid for if other commitments have been made for those
spaces in the interim.

     Landlord reserves the right at any time to relocate any parking spaces and 
to substitute an equivalent number of parking spaces in another parking 
structure or subterranean parking facility or in a surface parking area within a
reasonable distance of the Premises.

     Tenant agrees that it will use its best efforts to cooperate in programs 
which may be undertaken by Landlord independently, or in cooperation with local 
municipalities or governmental agencies or other property owners in the vicinity
of the Building, to reduce peak levels of commuter traffic. Such programs may 
include, but shall not be limited to, car pools, van pools and other ride 
sharing programs, public and private transit, and flexible work hours.

     Tenant and Tenant's Authorized Users shall comply with the Parking Rules 
and Regulations set forth in this Rider. Landlord reserves the right to modify, 
add, or delete from time to time such Parking Rules and Regulations as it deems 
reasonably necessary for the operation of such parking. Landlord may refuse to 
permit any person who violates the Parking Rules and Regulations to park in the 
Building parking facility, and any violation of the rules shall subject to the 
car to removal, at the vehicle owner's expense. Tenant agrees to use its best 
efforts to acquaint Tenant's Authorized Users and visitors with the Parking 
Rules and Regulations set forth in this Rider.


                         PARKING RULES AND REGULATIONS

1.   Neither Tenant nor Tenant's Authorized Users shall park vehicles in any
     parking areas designated by Landlord, the parking operator or governmental
     entities with jurisdiction for other uses, including use by visitors or
     other tenants. Tenant and such Authorized Users shall not leave vehicles in
     the Building parking areas overnight nor park any vehicles in the Building
     parking areas other than automobiles, motorcycles, motor driven or non-
     motor driven bicycles or four-wheeled trucks. Landlord may, in its sole
     discretion, designate separate areas for bicycles and motorcycles.

2.   Tenant shall not permit or allow any vehicles that belong to or are
     controlled by Tenant or Tenant's employees or Authorized Users, suppliers,
     shippers, customers, or invitees to be loaded, unloaded, or parked in areas
     other than those designated by Landlord for such activities. If Tenant
     permits or allows any of the prohibited activities described in this
     Parking Rider, then Landlord shall have the right, without notice, in
     addition to such other rights and remedies that it may have, to remove or
     tow away the vehicle involved and charge the cost to Tenant, which cost
     shall be immediately payable upon demand by Landlord.

3.   Tenant shall submit a written notice in a form reasonably specified by
     Landlord or the parking operator, containing the names, home and office
     addresses and telephone numbers of those persons who are designated as
     Authorized Users by Tenant to use the parking privileges on a monthly basis
     and shall use its best efforts to identify each vehicle by make, model and
     license number. Such notice, as amended from time to time, is hereafter
     referred to as the "Parking Notice." No person whose name and address is
     not contained in the Parking Notice shall have any right to park a vehicle
     in the area of the Building parking facilities designated for monthly
     parking, and no person whether or not his name is included in the Parking
     Notice shall have any right to park in such facilities a

                                     PR-1

<PAGE>
 
     vehicle not identified in the Parking Notice without paying the parking
     charge then applicable for daily parking and parking in the area designated
     for daily parking.

4.   Cars must be parked entirely within the stall lines painted on the floor.

5.   All directional signs and arrows must be observed.

6.   The speed limit within all parking areas shall be 5 miles per hour.

7.   Parking is prohibited, unless a floor parking attendant approved by 
     Landlord directs otherwise:

          a.   In areas not striped for parking;

          b.   In aisles;

          c.   Where "No Parking" or "Handicap" signs are posted (except that
               handicapped persons displaying on their vehicles the legalty
               prescribed identification may park in such "Handicap" areas);

          d.   On ramps;

          e.   In crosshatched areas; or

          f.   In reserved spaces and in such other areas as may be designated 
               by Landlord or the parking operator.

8.   Parking stickers or any other device or form of identification supplied by
     Landlord or the parking operator shall remain the property of Landlord or
     the parking operator, as the case may be. Such parking identification
     device must be displayed as requested and may not be mutilated in any
     manner. The serial number of the parking identification may not be
     obliterated. Devices are not transferable, and any device not in the
     possession of an Authorized User will be void. There will be a replacement
     charge to the Tenant or Authorized User for loss of any magnetic parking
     card or other parking identification device.

9.   Every Authorized User is requested to park and lock his own car. All
     responsibility for damage to or loss of cars is assumed by Authorized
     Users, and Landlord shall not be responsible for any such damage or loss by
     water, fire, defective brakes, the act or omission by others, theft, or by
     any other cause. Tenant shall repair or cause to be repaired at its sole
     cost and expense any and all damage to the Building parking facility or any
     part thereof caused by Tenant or its Authorized Users or vehicles of Tenant
     or such Authorized Users.

10.  Loss or theft of parking identification devices from automobiles must be
     reported to the garage manager immediately, and a lost or stolen report
     must be filed by the Tenant or user of such parking identification device
     at that time. Any parking identification devices found on any unauthorized
     vehicle will be confiscated and the illegal holder will be subject to
     prosecution. Lost or stolen devices previously reported and then found must
     be reported found to the office of the garage immediately. Landlord has the
     right to exclude any vehicle from the parking facilities that does not have
     a parking identification device.

11.  Spaces are for the express purpose of one automobile per space unless a
     floor parking attendant approved by Landlord directs otherwise. Washing,
     waxing, cleaning or servicing of any vehicle in the parking facility by
     Tenant or by the Authorized User and/or his agents is prohibited.

                             RENT ESCALATION RIDER
                             ---------------------


     In order to adjust the rent payable under the Lease in accordance with 
changes in the cost of living from time to time, Tenant agrees to pay to 
Landlord, with the installments of Base Rent, and as additional monthly rent 
under the Lease, an amount representing rent escalation. For purposes of 
calculating the rent escalation payable hereunder, the Consumer Price Index for 
All Urban Consumers, U.S. City Average, All Items (1967=100), unadjusted (herein
the "Index") published by the Bureau of Labor Statistics of the United States 
Department of Labor for the month of June, 1996 shall be the base Index figure 
(the "Base index"). The Base Index shall be compared to the index figure for 
December of each year during the term of the Lease, including the initial 
partial calendar year if the Lease term commences other than during December. In
the event that the Index figure for December of any year during the term of the 
Lease shall be greater than the Base Index, in addition to the Base Rent Tenant 
shall pay rent escalation to Landlord in an amount equal to the same percentage 
increase in the Base Rent as the percentage increase in the index for such 
December over the Base Index. Such amount shall be payable monthly commencing 
with the payment of Base Rent for the month following such December.

     In the event that the Index for any December during the term of the Lease 
is not yet available upon the date that any installment(s) of Base Rent is due, 
Tenant shall continue paying the monthly installments of Base Rent and rent 
escalation in the amount applicable for such December until the index for that 
month is published, whereupon Tenant shall immediately pay Landlord the rent 
escalation which would have been due in the months following such December had 
the index for such December been available. In the event that publication of the
Index is discontinued, Landlord and Tenant agree that the index of consumer 
prices which is most closely analogous to the index shall be used in place of 
the index for calculation of the rent escalation payable hereunder. In the event
that the referents or techniques employed in the calculation of the index shall 
be modified and such modification would have resulted in a different figure for 
the Base Index, Landlord and Tenant agree that the Base Index shall be 
appropriately adjusted and that the Index, as modified, shall be used as 
provided hereunder.

     The term "Base Rent" as used in this Rider shall be deemed to include the 
additional monthly rent for conduit space pursuant to Section 2 of the 
Telecommunications Conduit Rider (excluding the initial one-time payment of 
$7,200) as well as the Base Rent described in Section E on page 2 and Section 3 
on page 3 of the body of this Lease. Thus, the additional rent for the conduit 
space shall be adjusted from time to time in the same fashion as the Base Rent.

                       TELECOMMUNICATIONS CONDUIT RIDER
                       --------------------------------


     1.   Lease and Use of Conduit. Landlord hereby leases to Tenant, as part of
          ------------------------
the Premises for the Lease Term, the conduit space described below (the "Conduit
Space"). Tenant shall use the Conduit Space solely for telecommunications cable
to connect the Premises to the Premises of other telecommunications companies
that lease space on the floors of the Building through which the Conduit Space
passes. Any such connection shall require the mutual written agreement of Tenant
and the other affected telecommunications companies.

     The Conduit Space is contained within one 1-inch interduct running from 
floor 3 through floor 28.

     The interduct from floor 3 through floor 18 runs through conduit closets in
the northwest corner of the corridor on each floor. Access to the conduit closet
on each floor shall, at Landlord's election, be restricted so that no entry to 
the closet will be permitted unless Landlord's designated contractor or other 
representative is present. The interduct from floor 19 to floor 28 is located in
the north stairwell of the Building. Landlord may require any installation of 
cable in the Conduit Space or any connection of Tenant's cable to the Premises 
or cable of other tenants in the Building to be performed by Landlord's approved
contractor. All costs of such installations and connections (including but not 
limited to Landlord's administrative fee) and the ongoing use and maintenance of
such items shall be at Tenant's sole expense. Tenant shall pay Landlord any 
costs incurred by Landlord, together with Landlord's administrative fee, within 
ten days after Tenant's receipt of a bill for such items. Tenant's use of the 
Conduit Space and such cable and connecting lines shall comply with all 
applicable laws, the other provisions of the Lease, and such Building Rules as 
are adopted by Landlord from time to time, and shall not interfere in any way 
with the operation of the Building or with the use by any other tenant of the 
Building of such tenant's premises or the common areas of the Building. All 
required cabling and connecting lines shall be installed out of sight.

     Prior to any installation of cable in the Conduit Space or connecting lines
to the Premises or the premises of other tenants, Tenant shall obtain Landlord's
written approval as set forth in Section 29.3 of the Lease, and in the case of 
connecting lines to the Premises or cable systems of another tenant, obtain the 
written consent of such other tenants to the work.

     2.   Conduit Rent. Tenant agrees to pay Landlord additional rent for the 
          ------------
Conduit Space, which initially shall be a one-time payment of $7,200. Such 
$7,200 shall be due and payable upon execution of this Lease. (No portion of 
such payment shall be refundable if the Lease is terminated for any reason.) 
Thereafter, the additional rent for the Conduit Space shall be $50 per month 
during the remaining Lease Term, subject to adjustment as provided below. Such 
additional rent shall be due and payable to Landlord on the first day of each 
month or portion of a calendar month throughout the Lease Term, together with 
Tenant's Base Rent and other monthly charges, with the first such installment of
additional rent due on the Commencement Date. The amount of such monthly conduit
rent shall be adjusted from time to time in accordance with the Rent Escalation 
Rider to this Lease to reflect increases in the Consumer Price Index as 
described in that Rider.

     3.   Indemnity and Waiver. Tenant hereby agrees to indemnify and hold 
          --------------------
harmless Landlord and its partners, its agent Paramount Group, Inc. and their 
respective officers, directors, shareholders, agents and employees 
(collectively, the "Landlord Group") from and against any and all claims 
(including but not limited to claims for bodily injury or property damage), 
actions, mechanic's liens, losses, liabilities, and expenses (including 
reasonable attorney fees and costs of defense by Landlord's legal counsel) 
(collectively, "Claims"), which may arise from the installation, operation, use,
maintenance or removal of the cable and connecting lines pursuant to this Rider 
and the Lease. Similarly, Tenant shall pay upon demand by Landlord the costs to 
repair any damage to the Building caused by such installation, operation, use, 
maintenance or

                                     TCR-1

<PAGE>
 
removal. Tenant hereby waives and releases the Landlord Group from any Claims 
Tenant may have at any time (including but not limited to Claims relating to 
interruptions in services) arising out of or relating in any way to the 
installation, operation, use, maintenance, or removal of the cable and 
connecting lines described in this Rider and the Lease, whether or not caused by
the negligence of any member of the Landlord Group or Landlord's contractors. In
no event shall Landlord or any member of the Landlord Group be liable to Tenant 
for lost profits or consequential, incidental, or punitive damages of any kind.

     4.   Removal of Cable and Connecting lines.  Tenant agrees that, upon the 
          -------------------------------------
expiration or termination of the Lease, Tenant (or, at Landlord's election, the
contractor designated by Landlord) shall promptly remove, at Tenant's sole cost
and expense, all cable, connecting lines, and other installations installed
under this Rider and the Lease (excepting the interduct and conduit themselves,
which shall remain the property of Landlord), and restore those portions of the
Building damaged by such removal to their condition immediately prior to the
installation of such items. If Tenant fails to promptly remove all such items
pursuant to this Section 4, or if Landlord elects to have such work performed by
Landlord's contractor, Landlord may remove such items installed hereunder, and
restore those portions of the Building damaged by such removal to their
condition immediately prior to the installation, in which case Tenant agrees
promptly to pay Landlord's reasonable costs of removal and restoration,
including Landlord's administrative fee.

     5.   Applicability of Other Provisions.  Except as explicitly provided 
          ---------------------------------
otherwise herein, Tenant's obligaitons under the Lease for the protection of the
Building, Landlord, the Landlord Group, and third parties, including but not
limited to Tenant's obligations regarding maintenance, repairs, mechanic's
liens, insurance, attorneys' fees and costs of suit, shall apply in the same
fashion with respect to Tenant's use of the Conduit Space and the cable and
connecting lines described in this Rider as they do with respect to Tenant's use
of the rest of the Premises.

     6.   Miscellaneous.  This Rider supersedes all prior or contemporaneous 
          -------------
understandings, negotiations, or agreements between the parties, whether written
or oral, with respect to its subject matter.

                           EMERGENCY GENERATOR RIDER
                           -------------------------


     1.   The parties acknowledge that Landlord has installed a second Emergency
Generator in the Building which is in service as of the execution of this Lease.
Tenant is granted the right to use up to 20 kilowatts of emergency power from 
such Emergency Generator in the event of an interruption of normal electrical 
service to the Premises during the Lease Term, provided that: (a) Tenant 
notifies Landlord in writing within thirty (30) days following the Commencement 
Date of the number of kilowatts (not to exceed 20 kilowatts) of emergency power 
which Tenant reserves the right to use; (b) Tenant pays Landlord, at the time of
notification in (a) above, a one-time installation fee in an amount equal to 
$475 per kilowatt of emergency power so reserved; and (c) Tenant pays Landlord 
as additional rent under the Lease a monthly sum in an amount reasonably 
determined by Landlord in good faith based on the amount of emergency power 
reserved by Tenant, and Landlord's costs of operation, use, maintenance, fuel, 
oil, governmental permits, licenses and fees, insurance, Landlord's profit and 
administration and other expenses relating to the Emergency Generator. The 
monthly amount of the additional rent described in item (c) initially shall be 
$75 per month.

     2.   Each such payment described in subparagraph 1(c) above shall be due on
the first day of each month with Tenant's other rent payments, with the first 
such payment due on the Commencement Date. Such monthly amount may be adjusted 
annually, in Landlord's discretion, during the term of the Lease and any 
extensions thereto.

     3.   Tenant's use of such emergency power shall be in accordance with such 
rules and regulations as may be established by Landlord from time to time.

     4.   Landlord shall repair and maintain the Emergency Generator, provided 
that Tenant shall reimburse Landlord upon demand, as additional rent hereunder, 
for the cost of any repairs or extraordinary maintenance for the Emergency 
Generator necessitated by acts of Tenant or Tenant's employees, contractors, 
assignees, sublessees, agents, licensees or invitees. In addition, any 
installation of equipment or cabling in the Premises or the Building for the 
purpose of enabling Tenant to access the Emergency Generator shall be performed 
by Landlord in accordance with plans and specifications approved by the parties 
in writing in advance, and Tenant shall reimburse Landlord for the costs of such
installation, including, but not limited to, design fees and costs of 
demolition.

     5.   The provision of Emergency Generator service by Landlord to Tenant 
shall be subject to Section 9.6 of the Lease.

     6.   This Emergency Generator Rider supersedes all prior or contemporaneous
understandings, negotiations, or agreements between the parties, whether written
or oral, with respect to its subject matter. This Emergency Generator Rider is 
part of and shall be attached to the Lease.

     7.   All terms of the Lease which have not been expressly altered by this 
Emergency Generator Rider shall remain in full force and effect.

                            EXTENSION OPTION RIDER
                            ----------------------


     Provided that Tenant is not in default under this Lease, Tenant shall have 
the option to extend the term of this Lease for an additional five-year period 
following the expiration of the initial term. Tenant may exercise such option 
only by giving Landlord a written notice at least nine (9) months, but not more 
than twelve (12) months, prior to the commencement of the five-year period, and 
only if Tenant is not in default at the time Tenant gives such notice. If Tenant
has exercised such option, but is in default on the date the additional 
five-year extended term is to commence, then at Landlord's election, the 
extended term shall not commence until and unless the Tenant timely cures such 
default.

     With respect to the additional five-year term, the Lease shall be adjusted 
to reflect the following: (a) a new Base Rent for the Premises at a rate equal 
to the Base Rent rates being charged by Landlord for telecommunications space in
the Building of comparable size and quality in comparable renewal leases for a 
comparable term entered into by Landlord within six months prior to the date 
Tenant exercises this option (provided, however, that if no such comparable 
renewal leases were entered into within such six month period, then the 
valuation of comparable transactions shall be based on the Base Rent rate 
Landlord would have been willing to accept at that time in such comparable 
renewal leases, as reasonably calculated by Landlord in good faith); (b) a new 
rental rate for the Conduit Space based on the then-prevailing rate being 
charged by Landlord for similar conduits in the Building; and (c) a new rental 
rate for use of the Emergency Generator as provided for in the Emergency 
Generator Rider attached to the Lease, based on the then-prevailing rate charged
by Landlord for comparable usage.

     Landlord shall advise Tenant of such rental adjustments within one month 
after Landlord's receipt of Tenant's notice. Tenant shall have ten days 
following Tenant's receipt of notice of the rental adjustment within which to 
accept such terms by executing any appropriate documentation submitted by 
Landlord to Tenant. If Tenant fails to so accept such terms, Tenant's rights to 
extend the term pursuant to this Rider shall be cancelled.

     In no event shall the terms offered by Landlord under this Rider bind 
Landlord to offer such terms to Tenant or to any other person or entity at any 
time except as explicitly set forth in this Rider, nor shall such terms prevent 
Landlord from leasing the Premises to any person or entity on different terms if
Tenant does not timely accept the terms determined in accordance with this 
Rider.

              General Terms and Conditions for Carrier Agreements

[LOGO OF CABLE & WIRELESS, INC.
 APPEARS HERE]

1. Service to be Provided by CWI: CWI will provide the following long-distance
   -----------------------------
   services: Domestic Outbound, Domestic Inbound, International Outbound and
   Directory Assistance (hereinafter collectively, "Services").

   The Carrier will access CWI's network as soon as is reasonably possible, via
   dedicated T-1 lines ("Access Lines") ordered from local exchange carriers or
   alternate access carriers (collectively, "Local Carriers") and paid for by
   the Carrier. If the Carrier orders an Access Line from a Local Carrier, the
   Carrier will pay the Local Carrier directly for the Access Line. If the
   Carrier requests CWI to order the Access Line and if permitted by the Local
   Carrier, CWI will order the Access Line on behalf of the Carrier and will
   have the Local Carrier bill the Carrier directly for the Access Line.

2. Term and Termination: The initial term of this Agreement will end the number
   --------------------
   of full CWI monthly billing periods ("Month(s)") after service is initiated
   as set forth in the "Initial Term" portion of the Order Information section
   of this Agreement ("Initial Term"). Either party may terminate this Agreement
   at the end of the Initial Term, by providing thirty (30) days' prior written
   notice. If no such notice is given, this Agreement will continue after the
   Initial Term, until terminated by either party providing the other with
   thirty (30) days' prior written notice. The term "Term" as used herein will
   mean the Initial Term plus any subsequent period of time during which this
   Agreement continues beyond the end of the Initial Term. If CWI shall have
   undertaken efforts to provide Services prior to the date of full execution of
   this Agreement, the provisions of this Agreement shall apply retroactively
   with respect to such efforts and such Services.

   At any time prior to the end of the Initial Term, the Carrier may, for its
   convenience, terminate this Agreement in its entirety by providing CWI with
   thirty (30) days' prior written notice. In such event, in addition to paying
   for all charges incurred through the date service is discontinued, including
   any applicable shortfall charges, the Carrier will pay (as a contract
   discontinuance fee and not as a penalty) an amount equal to the sum of the
   minimum monthly payment obligations for each of the remaining Months in the
   Initial Term.

   If CWI has not received any traffic from Carrier hereunder within sixty (60) 
   days after full execution of this Agreement, CWI shall have the right to 
   terminate this Agreement upon written notice to Carrier.

   If the Carrier fails to do any of the following when due and then does not
   cure such failure within two (2) days after receiving notice thereof from
   CWI, CWI may, in addition to any other remedies available to it and without
   any further written notice to the Carrier, immediately terminate this
   Agreement in its entirety and discontinue providing Services: (i) make a
   payment in full; (ii) provide any required security deposit amount; or (iii)
   provide any required financial report. In addition to any other remedies
   available to it, CWI may immediately terminate this Agreement in its entirety
   if Carrier fails to comply with the terms of any license accompanying any
   software relating to E-BIS(R) reporting options.

3. Rates and Taxes: The Carrier will pay the monthly, non-recurring and usage
   ---------------
   charges set forth in this Agreement. Each call will be billed in 6-second
   increments and will be subject to a 30-second minimum charge except that
   domestic outbound calls (both interstate and intrastate) will be subject to a
   6-second minimum charge. The Carrier will pay any applicable federal, state,
   or local taxes, surcharges, or similar fees for the Services.

   CWI may, upon fifteen (15) days written notice to Carrier, increase any of
   the rates for any of the countries set forth in this Agreement. If Carrier
   subsequently discontinues routing traffic to CWI for a country for which such
   increased rate applies and providing traffic to such country would have
   contributed to the Carrier's minimum monthly payment obligations set forth in
   the Order Information section of the Agreement, then, for so long as Carrier
   discontinues routing traffic to such country to CWI, the amount of such
   minimum monthly payment obligations will be reduced by a percentage that is
   equivalent to the average total charges incurred by the Carrier for calls
   placed to that country in each of the three (3) Months immediately preceding
   the date the Carrier discontinues routing such traffic to CWI, divided by the
   average of the Carrier's total charges for Services in each such month.

   Any software which CWI supplies for use in connection with the E-BIS(R)
   reporting options shall be provided subject to the software license agreement
   that accompanies such software. Carrier agrees to comply with all terms and
   conditions set forth in such software license agreement. Title to, all rights
   to and all interest in, such software shall at all times remain with CWI or
   its third-party suppliers.

4. Payment: CWI will provide monthly invoices covering CWI-designated periods
   -------
   which will be due and payable within the number of days after the invoice
   date as set forth in the "Payment Period" section of the Order Information
   section of this Agreement. The "invoice date" for a particular monthly
   billing period will be the day immediately following the last day of such
   monthly billing period. For example, if the monthly billing period runs from
   January 24th to February 23rd, the invoice date for such billing period will
   be February 24th, and, if the "Payment Period" set forth in the Order
   Information section of the Agreement is "10 days after invoice date", then
   payment for such monthly billing period is due no later than the tenth
   (10th) day after February 24th.

   If the Order Information section of this Agreement indicates that estimated
   payments are required, CWI will notify the Carrier on the last day of the
   "Estimated Usage Period," or if such day is not a business day, on the next
   business day, as to CWI's estimate of the charges incurred by the Carrier
   during such period. The Carrier will pay CWI such estimated amount
   ("Estimated Payment") no later than the "Estimated Payment Due Date". At the
   end of a Month, CWI will provide an invoice for the usage charges actually
   incurred that Month less that Month's Estimated Payment; provided, however,
   that if a minium monthly payment obligation applies for that Month and such
   minimum has not been met, then the invoice amount will be that Month's
   minimum payment obligation less that Month's Estimated Payment. The Carrier
   will pay the invoiced amount within the Payment Period.

   A late payment charge will be applied on balances that remain unpaid after
   the Payment Period in the amount of the lesser of (a) 1 1/2% per month of the
   amount of the late payment starting from the day following the Payment
   Period, or (b) maximum amount allowed under applicable law. The Carrier must
   pay all invoices when due; any questions which the Carrier may have
   concerning an invoice must be brought to CWI's attention within forty-five
   (45) days of the invoice date. The Carrier shall reimburse CWI for any
   expenses, including, without limitation, reasonable attorney's fees, CWI may
   incur in collecting amounts due hereunder.

   If so indicated in the Order Information section of this Agreement, all
   payments by the Carrier will be made via wire transfer (in immediately
   available funds) to Mellon Bank, 3 Mellon Bank Center, Room 153-2718,
   Pittsburgh, PA 15259-0001, ABA #0430-00261/Account #1705643.

5. Financial Reports: If the Order Information section of this Agreement
   -----------------
   indicates that financial reports are required, within thirty (30) days after
   the end of each calendar quarter, the Carrier will provide CWI with a written
   report updating the Carrier's financial status ("Quarterly Report"), and
   within ninety (90) days after the end of each calendar year, the Carrier will
   provide CWI with an audited annual report. Each Quarterly Report will
   contain, as a minimum, an updated balance sheet and income statement. The
   Carrier represents and warrants that no Quarterly Report will contain any
   material misstatement or omission.

6. Security Deposits: If the Order Information section of this Agreement
   -----------------
   indicates that security deposits are required, each required security deposit
   will be either in cash (paid by check or via wire transfer) on an irrevocable
   stand-by letter of credit in a form and from a financial institution
   reasonably acceptable to CWI. The "Initial Security Deposit" amount will be
   provided prior to the initiation of service. Thereafter, if requested in
   writing by CWI, the Carrier will add additional amounts to the Initial
   Security Deposit such that the total amount of security deposit being held by
   CWI at all times is at least equal to the "Continuing Security Deposit". The
   Carrier will provide any such required additional amounts within five (5)
   business days after receiving CWI's written request. CWI will refund or
   release, as applicable, any security deposit it is holding (plus, if the
   security deposit is in the form of cash, accrued interest at the applicable
   rate set by regulation of the state in which CWI invoices the Carrier, or if
   no such rate is set by regulation, CWI's then-prevailing interest rate for
   security deposit refunds) if the following conditions are met by the Carrier:
   (i) for the entire "Deposit Release Period", the Carrier pays CWI in full
   when each payment is due; and (ii) CWI determines that the Carrier's
   Quarterly Reports covering the Deposit Release Period indicate that the
   Carrier's financial condition has had no materially adverse change as
   compared to the equivalent period of time immediately prior to the start of
   the Deposit Release Period. If CWI does not refund or release the security
   deposit during the Term as set forth above, the security deposit will be
   refunded or released, as applicable, at the end of the Term. If, at any time
   during the term of the Agreement, CWI determines that there has been a
   materially adverse change in the Carrier's financial condition as compared
   with the equivalent period of time immediately prior to the Effective Date,
   CWI may require Carrier to provide a security deposit or an additional
   security deposit in an amount to be determined by CWI. The Carrier shall
   provide any such required amounts within five (5) business days after
   receiving CWI's written request therefor.

7. Minimum Payment Obligations: If the total amount of usage charges incurred by
   ---------------------------
   the Carrier for international service in any Month is less than the amount of
   the then-applicable minimum monthly payment obligation set forth in the Order
   Information section of this Agreement, then in addition to paying for its
   actual usage that Month, the Carrier will pay (as an underutilization fee and
   not as a penalty) a shortfall charge equal to the difference between (i) the
   actual usage charges incurred for international service that Month, and (ii)
   the amount of the then-applicable minimum monthly payment obligation. If this
   Agreement remains in effect after the Initial Term, the minimum monthly
   payment obligation for each subsequent Month, shall be equal to the amount of
   the minimum monthly payment obligation for the last Month of the Initial
   Term.

8. Additional Terms: This is a carrier-to-carrier agreement subject to (S)211 of
   ----------------
   the Communications Act of 1934, as amended. The Carrier is responsible for
   and shall comply with any and all legal and regulatory requirements with
   respect to the Carrier's use and resale of the Services, including those of
   the Federal Communications Commission and state public utility commissions.
   The Services are governed by this Agreement and all Carrier obligations and
   CWI rights as set forth in the "General Rules and Regulations" section of
   CWI's interestate tariff, as may be amended by CWI in accordance with
   applicable laws and regulations. The Carrier shall defend, indemnify and hold
   CWI harmless from and against all claims, demands, actions, causes of action,
   judgments, costs and reasonable attorneys' fees and expenses of any kind
   arising from or related to any use of the Service or otherwise arising under
   this Agreement. In no

4.        Charges and Payment Terms
          -------------------------

          (A) STAR and CUSTOMER hereby acknowledge the charges for the provision
of Services will be billed as provided herein and that payment for such Service
shall be payable in U.S. dollars. For each month during the term of this
Agreement, STAR and CUSTOMER will provide the other party with an invoice for
Service provided during the previous month. The invoice amounts will be due and
payable from both parties within twenty (20) days after the invoice date (the
"Due Date"), which shall be the last date of the previous month's billing cycle.
Late payments will be assessed a late payment penalty of one and one-half
percent (1.5%) per month on the delinquent balance of any undisputed Service
usage not paid by the Due Date. Payments shall be made by wire transfer or such
other methods as may be agreed by the parties. Nothing herein shall be construed
to constitute a waiver of either parties rights to declare a default by the
other party under this Agreement on account of delinquency, to terminate this
Agreement and to exercise any other rights under this Agreement or at law or in
equity.

          (B) Should either STAR or CUSTOMER dispute any of the monthly charges
on the monthly invoice, it shall notify the other party of the disputed charges
not later than sixty (60) days from the date of invoice. Said dispute shall set
forth all details concerning the disputed charges in writing. In the event of a
dispute, the entire invoice shall nevertheless by paid in accordance with
payment terms set forth herein. After resolution of the disputed portion of the
invoice, the adjustments, if any shall be immediately credited to the other
party's account.

          (C) All calls will be billed in six (6) second increments utilizing
Hardware Answer Supervision where available. All international calls, with the
exception of Mexico, will be billed in six (6) second increments subject to a
thirty (30) second minimum charge. Mexico calls will be billed in one (1) minute
increments.

          (D) CUSTOMER and STAR shall at all times comply with the other party's
initial and continuing credit approval procedures and policies. Each party
reserves the right to withhold initiation and full implementation of services
under this Agreement pending initial satisfactory credit review and approval
thereof, which may be conditioned upon terms specified, including, but not
limited to, security for payments due hereunder in the form of a cash deposit,
guarantee, irrevocable letter of credit or other means. Upon request by either
party, at any time, the other party agrees to provide financial statements or
other indications of financial circumstances. As may be determined by either
party, in its sole discretion, at any time, if the financial circumstances or
payment history of the other party is or becomes unacceptable, the party
furnishing Services may require a new or increased deposit, guarantee or
irrevocable letter of credit, at such party's option, to secure the other
party's payments for the term of the Agreement. Failure of a party to provide
requested security shall permit the other party to immediately suspend Services,
without further notice or demand, until such time as requested security is
provided.

payment when due.

                    SWITCH PORT LEASE AND SERVICE AGREEMENT


      This Switch Port Lease and Service Agreement ("Agreement") is hereby
entered into as of this 7th [handwritten] day of August [handwritten], 1996 and

having its principal offices at 300 120th Ave., NE, Building One, Suite 204,
Bellevue, Washington 98005 and PrimeCall, Inc., a Washington corporation
(hereinafter "Lessee") having its principal offices at 1520 Eastlake Ave., E,
Suite 205, Seattle, Washington 98102 (collectively "Parties").

      The Parties agree as follows:

      1. Lease of Ports. Subject to the terms and conditions contained herein,
         --------------
Lessor hereby leases to Lessee, and Lessee hereby leases from Lessor the
quantity of DS-1 ports (set forth in Exhibit "A") on a Northern Telecom DMS-250
Switch (the "Switch"), located at 625 So. Grand Avenue, 7th Floor #711, (1
Wilshire Bldg.), Los Angeles, California 90017 to receive, process, and output
voice grade telephone message traffic.

      2. Term. This Agreement and the services contemplated hereunder shall not
         ----                                                                   
become effective until Lessee pays to Lessor $[*] representing first months
rental payment. Unless sooner terminated as provided herein, this Agreement
shall have a initial term of six (6) months (the "Initial Service Term")
commencing on the date set forth above. After the initial Service Term, service
shall automatically continue on a month-to-month basis (each month period is
referred to as an "Extended Term"), unless terminated by either party at the end
of the Initial Service Term or an extended Term, by giving at least 60 days
written notice of intent to terminate prior to the end of such Term. All terms
set forth herein shall apply to any 'Extended Term' of this Agreement.

      3. Charges, Payment and Billing. 
         ----------------------------   

         a. Lessee will pay Lessor monthly for the lease of ports and services
provided pursuant to this Agreement. As of the execution date of this Port
Agreement, the charges which apply are set forth in Exhibit "A" attached hereto.
Charges for ports will be paid in advance each month. In-use port charges
commence when the ports are activated in accordance with Section 6. Ports placed
in In-Use during a partial calendar month shall still be charged at a rate equal
to the full monthly In-Use port rate.

         b. Payment. Lessee agrees to remit any payment due to Lessor pursuant
to this Agreement on the first of each month (the "Due Date") . Any payment

<PAGE>
 
received more than thirty (30) days after the first of the month shall
constitute a late payment resulting in a late payment charge of 1.5% of the
total invoice amount per month of the maximum legal rate, whichever is less. If
the total amount due on any invoice is not received by Lessor within fifteen
(15) days of the Due Date, Lessor may send Lessee written notice that all
services may be temporarily suspended due to non-payment. Lessor shall have the
right after ten (10) days following such notice to discontinue services pursuant
to this Agreement unless or until the total amount due including late payment
charges is paid in full by Lessee.

         c. Disputes. In the event of any billing disputes, Lessee will provide
to Lessor, prior to Due Date, a detailed presentation in writing of any disputed
charges. Notwithstanding such dispute Lessee shall pay any undisputed portion of
the disputed invoice. Any dispute by Lessee must be raised within sixty (60)
days of the Due Date, or such disputed claim is hereby waived. Disputes will be
resolved in accordance with the procedures outlined in paragraph 14(j).

         d. Additional Charges. Any applicable federal, state, or local use,
excise, sales, or privilege taxes, duties, or similar liabilities, chargeable to
or against Lessor because of the services provided to Lessee pursuant to this
Agreement shall be charged and payable by Lessee in addition to the other charge
specified in this Section 3. Any extra services provided by Lessor to Lessee
shall be billed to Lessee and paid within ten (10) days of invoice provided that

ports. Such routing procedure is to be implemented after a mutually acceptable
initial routing procedure has been approved by both parties. Lessee shall
provide Lessor with a written listing of all the output NPA-NXX's and country
codes to be entered into the Initial Routing Tables and shall specify the output
port(s) to which each NPA-NXX or country code, Lessee agrees that traffic bound
for that NPA-NXX or country code will be intercepted by the Switch and treated
with an announcement, or routed to a trunk group designated by Lessee. When
input to the Initial Routing Tables has been completed, Lessor shall provide
Lessee with a paper printout of the Initial Routing Tables. Lessee agrees:

                i.    to review the Initial Routing Tables to verify their 
accuracy;

of receipt of the printout of any error; and

                iii.  to specify changes needed to the Initial Routing Tables

      Input to all tables will be considered correct and accepted by Lessee
unless Lessor is notified within five (5) business days otherwise.

Tables resulting in revised routing tables (the "Revised Routing Tables"), which

routing procedures specified in Exhibit B.

      8. Service Outage Recovery. Lessor agrees to work with Lessee to develop a
         ----------------------- 
mutually acceptable plan for alternative routing of Lessee traffic to mitigate
the outage in the event of a disaster or major Switch outage.

      9. Defaults and Remedies. It shall be a default under this Port Agreement,
         ---------------------

to cancel this Agreement effectively immediately.

      10. Required Termination. Either party shall also have the right, whether
          --------------------
or not a default shall have occurred, to terminate this Agreement prior to the
expiration of the Initial Service Term or any Extended Term, upon no less than
thirty (30) days prior written notice to the other party if either party is
prohibited from furnishing any service related solely to this Agreement by order
of any court, the Federal Communications Commissions, or any other government
authority having jurisdiction as a result of any change in circumstance
occurring after creation of this Agreement; and in the event of early
termination under the paragraph, neither party shall have any continuing
obligation or liability to the other, except for such obligations or liabilities

         c. The Indemnifying Party will not be liable under this section for
settlements by the Indemnified Party of any claim, demand, or lawsuit unless the
Indemnifying Party has approved the settlement in advance or unless the defense
of the claim, demand, or lawsuit has been tendered to the Indemnifying Party in
writing and the Indemnifying Party has failed promptly to undertake the defense.

         d. Indemnified party is defined to include directors, officers,

                                   EXHIBIT B

                    Routing Table Change Request Procedure

      Both parties to this Port Agreement dated 8/7, 1996,
                                                ---
understand that procedures should be established and followed to assure that
required routing changes are executed accurately and in a timely and cost
efficient manner. Lessor agrees to work with Lessee to customize the basic
procedures set forth below in ways which are mutually acceptable for achieving
these goals.

      1. Submitting Requests. Change requests must be made in writing and must
         -------------------
indicate exactly how the Routing Table data is to appear after the change.
Lessee may submit changes to Lessor via first-class mail, recognized courier or
facsimile transmission. In order to expedite processing, Lessor may request that
changes be sent to the attention of a particular individual or department and/or
that a particular form or format be used. Lessee shall pay for all changes
within 10 days of receipt of an invoice from Lessor.

      2. Acknowledging Receipt. Lessor shall acknowledge receipt of change
         --------------------- 
requests by facsimile transmission on the next business day after receipt of
Lessee's written request. If Lessor fails to acknowledge receipt of a change
request within one business day, Lessee should call Lessor to confirm receipt or
resubmit the request. Change requests will not be deemed received unless
acknowledged by Lessor.

      3. Timing of Input. Lessor shall review all change requests and contact
         ---------------
Lessee for clarification of the request, if applicable, within a reasonable
period of time after acknowledging receipt. A reasonable period of time for
reviewing the request generally will not exceed the next business day after the
receipt of the request. The change request will generally be completed within
the next business day following acknowledgment of Lessor's receipt of written
clarifications, if any from Lessee. Should Lessee request that any routing
change be completed by Lessor in less than the time interval specified above,
Lessor will use its best efforts to comply with Lessee's requests at an extra
charge. Lessee will always attempt to limit expedited changes to emergency
situations.

      4. Acknowledging Input. Within 1 business day following completion of
         -------------------
input, Lessor will send Lessee, via first-class mail, recognized courier or
facsimile transmission, a hard copy of print out of the changed routing tables
showing the contents before and after changes were made. Lessee shall review the
input to verify its accuracy. Completed changes will be considered correct and
accepted by Lessee unless Lessor is 

                                       12
<PAGE>
 
notified otherwise within the next business day after the information was
received or five (5) days after it is sent, whichever is less.

      5. Data Base Management. Lessee shall be allowed direct input control via
         --------------------
password protected software of the routing, management, and authorization code
data base on the switch under a mutually acceptable procedure for security and
implementation. Any other user of the switch shall coordinate their input
process in conjunction with the Lessor procedures. However, such input control
and access does not allow Lessee to make changes to any data base or routing
other than that associated with Lessee.

<PAGE>
 
      4. If required by Lessee, due to billing link failure, Lessor will send a
billing tape of lost raw detail call records to Lessee. Lessee will be

industry standards. Lessor's failure of any of the provisions herein and failure
to remedy such deficiency within five days of notice shall constitute a material
breach of the terms and conditions of the Agreement for purposes of Paragraph 9.

MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, WITH RESPECT TO THE
MATTERS COVERED HEREIN.

11.   Indemnification. Limitation of Liability.
      -----------------------------------------

      11.1. Each party (the "indemnifying party") agrees to indemnify, defend,
and hold harmless the other party, its officers, directors, employees, and
agents, from any and all third party causes of action, claims, demands, damages,
liabilities, costs, and expenses (including without limitation reasonable
attorneys' fees and costs) (hereinafter referred to as "Claims") arising out of
or in connection with any claim which, if true, would be a breach of the
indemnifying party's warranties, representations, or obligations under this
Agreement. If any action shall be brought against a party under this Agreement
in respect to which indemnity may be sought hereunder, the party claiming such
indemnity shall promptly notify the other party in writing, specifying the
nature of the Claim and the total monetary amount sought or other such relief as
is sought therein. The indemnified party shall cooperate with the indemnifying
party in all reasonable respects in connection with the defense of any Claim.
Except as otherwise provided herein, the indemnifying party may upon written
notice to the indemnified party undertake to conduct all proceedings or
negotiations in connection with a Claim, and assume the defense thereof, and, if
it so undertakes, it shall also undertake all other required steps or
proceedings to settle or defend any such Claim at its own expense. Each party
shall have the right to employ separate counsel and participate in the defense
of any Claim hereunder. The indemnifying party shall reimburse the indemnified
party hereunder upon demand for any payment made by such indemnified party that
is based upon the judgment of any court of competent jurisdiction or pursuant to
a bona fide compromise or settlement of any Claim; provided, however, that the
indemnifying party shall not be responsible for any settlement made by the
indemnified party without the indemnifying party's written approval, which shall
not be unreasonably withheld.

      11.2. IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER FOR ANY
INDIRECT, CONSEQUENTIAL, INCIDENTAL, SPECIAL, OR PUNITIVE DAMAGES (INCLUDING
WITHOUT LIMITATION DAMAGES FOR LOSS OF BUSINESS PROFITS, BUSINESS INTERRUPTION,
LOSS OF BUSINESS INFORMATION, OR OTHER PECUNIARY LOSS) ARISING OUT OF THIS
AGREEMENT.

12.      Miscellaneous.
         --------------

franchise, employment relationship or joint

service related to this Agreement with regard to compliance with all applicable
laws, rules and regulations governing such party relating to employment, labor,

      12.3. The failure of any party to enforce its rights, remedies or any

consent shall not be unreasonably withheld. For purposes of this Agreement, a
"change in control" shall mean the acquisition of more than fifty percent (50%)
of any class of either party's voting stock by another entity, or the sale of

         (i) amounts due and amounts paid under a Statement of Work, and (ii)
         [*]. The parties shall have the right, at their own expense and upon no
         less than fifteen business days prior written notice, to audit the
         other party's records. Such audit may be conducted by a party's own
         audit team or by its authorized representative(s), shall not interfere
         unreasonably with the other party's business activities, and shall be
         conducted no more often than once per calendar year, unless a previous
         audit disclosed a material discrepancy. If such audit shows that a
         party has underpaid amounts owing, that party shall immediately pay all
         amounts owning. If such audit shows that a party has underpaid amounts
         owing by more than five percent (5%), the defaulting party shall also
         pay the reasonable expenses of the audit. Each party shall use the
         information obtained from any such audit solely to determine the other
         party's compliance or non-compliance with this Agreement and any
         Statement of Work and to remedy any non-compliance. Each party shall
         otherwise maintain the confidentiality of all such information.

     e.  Tax Consequences. Unless otherwise explicitly stated in this MTA or in
         ----------------
         a Statement of Work, the party making a payment to the other party will
         be responsible for all sales or equivalent taxes arising out of the
         payment and will either include such taxes with the payment or will
         provide the other party with a resale certificate or other
         documentation to successfully claim exemption from the tax. Each party
         will be responsible for payment of all income or equivalent taxes based
         upon that party's net income.

     f.  Late Payment. For any payment made late than the appropriate payment
         ------------
         date, the party making the payment will pay the other party a late fee
         of one and one-half percent of the amount paid late for each calendar
         month beyond the payment date.

7.   INVENTIONS AND PATENTS UNDER A STATEMENT OF WORK. Each Statement of Work
     ------------------------------------------------
     will be deemed to incorporate by reference this Section 7 unless the
     Statement of Work explicitly states otherwise.

     a.  Patent License. If a Statement of Work states that a copyright license
         --------------
         to certain Materials is granted by one party to the other, then such
         Statement of Work will automatically include a grant by the Copyright
         Licensor to the Copyright Licensee of a worldwide, non-exclusive, paid-
         up and royalty-free license under the Copyright Licensor's patents,
         inventor's certificates, and utility models (and similar forms of legal
         protection of any country) and applications therefor, to make, have
         made, use and sell those certain Materials. Such license will be
         limited in scope

          to the minimum extent that is consistent with the grant of the
          copyright license. Such patent license is also extended, at the
          minimum scope necessary to be consistent with the grant of the
          copyright license, to the Copyright Licensee's agents, distributors
          and customers.

     b.   Ownership Of Inventions.  If an invention, whether or not patentable,
          -----------------------
          is conceived or reduced to practice by one or more employees of one of
          the parties, then that party will own such invention and all patents 
          and patent applications on the invention. If an invention, whether or
          not patentable, is conceived or reduced to practice jointly by one or
          more employees of each of the parties, then each party will own such
          invention and all patents and patent applications on the invention
          jointly with the other party without any duty to account for profits
          to the other party, and each party may freely license third parties.

8.   TERM AND TERMINATION.  Each Statement of Work will be deemed to incorporate
     --------------------
     by reference this Section 8 unless the Statement of Work explicitly states
     otherwise.

     a.   MTA.  This MTA will be effective upon the date specified at the
          ---
          beginning of this MTA, and will remain in force for a period of [*],
          unless otherwise terminated as provided in Section 8.c. After this
          initial term of [*], this MTA will automatically renew for additional
          terms of [*] each, unless 90 days or more prior to the end of either
          the initial term or any subsequent term either party provides the
          other party with written notice terminating this MTA.

     b.   Statements of Work.
          ------------------

          (1)   Term Of A Statement of Work.  The Statement of Work will enter 
                ---------------------------
                into effect upon its effective date and will continue in effect
                for the term specified in the Statement of Work unless earlier
                extended, terminated by mutual written agreement of the parties,
                or terminated for cause in accordance with Section 8.c below.
                In the event that a Statement of Work fails to contain a term, 
                the Statement of Work will be deemed to have a term of [*] and
                will be subject to the termination provisions provided in
                Section 8.c.

          (2)   Relationship to MTA.  As long as a Statement of Work is in 
                -------------------
                effect this MTA will remain in effect.

     c.   Termination for Cause.  Either party may terminate this MTA or a 
          ---------------------
          Statement of Work for the substantial breach by the other party of a
          material term.  The terminating party will first give the other party
          written notice of the alleged breach and a reasonable period of at
          least 90 days in which to cure the alleged breach.  If a cure is not
          achieved during the cure period, then the parties will enter into the
          dispute resolution procedures specified in Section 9.f below.  
          Termination of the Statement of Work will occur upon the expiration of
          the cure period and the

          subsequent unsuccessful completion of the dispute resolution 
          procedures specified in Section 9.f below.

     d.   Insolvency, Assignment, or Bankruptcy.  Either party may terminate 
          -------------------------------------
          this MTA or a Statement of Work upon written notice to the other party
          if the other party (i) is not paying its debts as such debts generally
          become due, (ii) becomes insolvent, (iii) files or has filed against 
          it a petition (or other document) under any Bankruptcy Law or similar
          law, which is unresolved within sixty (60) days of the filing of such 
          petition (or document), (iv) proposes any dissolution, liquidation,
          composition, financial reorganization or recapitalization with 
          creditors, (v) makes a general assignment or trust mortgage for the 
          benefit of creditors, or (vi) if a receiver, trustee, custodian or
          similar agent is appointed or takes possession of any of its property
          or business.

     e.   Survival Of Terms.  In the event of a termination of a Statement of 
          -----------------
          Work, all obligations of confidentiality (including those specified in
          Section 9.c below) will continue in effect in accordance with their 
          terms.  In addition, the terms of Section 9.k (Intellectual Property 
          Indemnity), Section 9.n (Limitation Of Liabilities), and Section 9.q
          (Representations And Warranties) will continue in effect in accordance
          with their terms.

9.   GENERAL TERMS.  Each Statement of Work will be deemed to incorporate by 
     -------------
     reference this Section 9 unless the Statement of Work explicitly states 
     otherwise.

     a.   Assignment.  Except as otherwise provided herein, neither party may 
          ----------
          transfer or assign any right or obligation set forth in this MTA or in
          a Statement of Work without the prior written consent of the other
          party. Any such attempted transfer or assignment will be void.
          Notwithstanding the above, either party may assign any right or
          obligation in this MTA or in a Statement of Work in connection with a
          corporate merger by that party or a sale of substantially all of its
          assets.

     b.   Changes To This MTA Or To A Statement of Work.  This MTA or a 
          ---------------------------------------------
          Statement of Work may only be modified in a writing that is executed
          by authorized representatives of both parties. A change to this MTA
          will not affect any Statement of Work that is already in effect when
          the MTA is changed unless the parties agree in writing that the change
          to this MTA will affect that Statement of Work. The parties will
          indicate the level of revision to this MTA by assigning each revised
          MTA a new MTA agreement number.

     c.   Confidentiality And Information Exchange.  It is the intention of 
          ----------------------------------------
          GlobalTel and Novell to transfer and/or exchange information,
          including confidential information, as may be necessary under the
          Statements of Work.  Such information may be disclosed in oral, 
          visual, or written form (including magnetic media).  Novell and
          GlobalTel agree that all Source Code received under a Statement of 
          Work (or

================================================================================
                                    PAGE 13                Master Task Agreement

Novel/GlobelTel Confidential                                  Execution Original
================================================================================

     developed from Source Code received under a Statement of Work) will be
     considered to be confidential information for the purposes of this Section
     9.c.

     (1)  The party receiving confidential information under a Statement of Work
          ("Recipient") will make use of the confidential information only for
          the purposes of that Statement of Work. However, this Section 9.c.(1)
          will not be construed to limit either party's right to independently
          develop or acquire products without use of the other party's
          confidential information. Further, either party will be free to use
          the residuals resulting from access to or work with the other party's
          confidential information, provided that such party otherwise complies
          with these nondisclosure provisions. The term "residuals" means
          information in non-tangible form which may be retained by persons who
          have had access to the confidential information.

     (2)  The Recipient will protect the disclosed confidential information by
          using the same degree of care, but no less than a reasonable degree of
          care, to prevent the unauthorized use, dissemination, or publication
          of the confidential information as the Recipient uses to protect its
          own confidential information of like nature.

     (3)  The Recipient's duty to hold confidential information in confidence
          expires (i) [*] after its return or destruction in the case of
          confidential information embodied in received or developed (whichever
          is later) source and related descriptions, specifications and system
          documentation, or (ii) in the case of any other confidential
          information, [*] after the MTA terminates. The expiration of the duty
          of confidentiality will not modify other restrictions on the Recipient
          including, for example, any restrictions on distribution of Source
          Code arising out of granted copyright license.
     
     (4)  [*]

     (5)  This MTA and the Statement of Work impose no obligation upon Recipient
          with respect to information that: (a) was in Recipient's possession
          before receipt from the disclosing party ("Discloser"); (b) is or
          becomes a matter of public knowledge through no fault of Recipient;
          (c) is rightfully received by the Recipient from a third party without
          a duty of confidentiality; (d) is disclosed by the Discloser to a
          third party without a duty of confidentiality on the third party; (e)
          is independently developed by the Recipient without thereby violating
          the Discloser's patent or copyright; (f) is disclosed under operation
          of law after all reasonable means have been afforded to the

              Discloser to protect the information; or (g) is disclosed by the
              Recipient with Discloser's prior written approval.

     d.   Construction.  The headings in this MTA and in the Statements of Work 
          ------------
          are provided for reference only and will not be used as a guide to
          interpretation. When used in this MTA or in a Statement of Work, the
          singular includes the plural and the plural includes the singular, and
          gender related pronouns include the feminine, masculine and neuter.

     e.   Copyright Notices.  Each party will ensure that all copyright notices 
          -----------------
          of the other party that are marked on or included in any portion of
          Materials under a Statement of Work will be marked on or included at
          least once in each copy or Derivative Work of the Materials.

     f.   [*]

     g.   Entire Agreement.  A Statement of Work, including the incorporated 
          ----------------
          portions of this MTA, sets forth the entire agreement and 
          understanding between the parties as to its specific subject matter
          and merges all prior discussions between them with regard to such
          specific subject matter.  Neither of the parties will be bound by any 
          conditions, definitions, warranties, understandings, agreements, or
          representations, whether written or oral, with respect to such
          specific subject matter other than as expressly provided in the 
          Statement of Work or as duly set forth on or subsequent to its
          effective date, in a written document that is signed by a duly
          authorized representative of each Party.  However, the parties 
          acknowledge that they do not intend, at the present time, to merge any
          independent written agreements existing between them and executed 
          prior to the execution of this MTA, and such independent agreements
          will not be considered merged into this MTA or into any Statement of
          Work except as specifically set forth in a Statement of Work executed
          under this MTA.

     h.   Export of Technical Data.  Regardless of any disclosure made by one 
          ------------------------
          party to the other of an ultimate destination of the Licensed Work,
          neither party will transfer, export or re-export or cause to be
          exported or re-exported, directly or indirectly, any Licensed Work or
          technical information or direct product thereof or Confidential
          Information received from the other party to anyone outside the United
          States without first complying strictly and fully with all export
          controls that may be imposed on the Licensed Work, technical 
          information or direct product

     thereof or confidential information by the United States Government or any
     country or organization of nations within whose jurisdiction the party
     operates or does business. In particular, each party assures the other
     that, absent any required prior authorization from the Office of Export
     Licensing U.S. Department of Commerce, 14th and Constitution Avenue,
     Washington D.C. 20230, that party will not export or reexport (as defined
     in Section 779 of the Export Administration Regulations, as amended
     ("Regulations")) the Licensed Work or any technical data or other
     confidential information, or direct product of any of the foregoing, to
     Iraq, Iran, Syria, or any Group S or Z country specified in Supplement No.
     1 to Section 770 or the Regulations which, as of the date of this contract,
     include the countries of Libya (Group S), and North Korea, Cuba (Group Z),
     or such other countries as come under restriction by action of the United
     States Government, or to nationals from or residing in the foregoing
     contries, without first obtaining permission from the appropriate United
     States Government authorities. The countries subject to restriction by
     action of the United States Government are subject to change, and it is
     each party's responsibility to comply with the United States Government
     requirements as they may be amended from time to time.

i.   Force Maleure. Neither party will be liable in damages or have the right to
     -------------    
     cancel or terminate this MTA or any Statement of Work for any delay or
     default in performance if such delay or default is caused by unforeseen
     conditions or conditions beyond the control of the delaying or defaulting
     party, including but not limited to acts of God, government restrictions,
     continuing domestic or international problems such as wars or
     insurrections, strikes, fires, floods, work stoppages and embargoes. Either
     party will have the right to terminate a Statement of Work upon 60 days
     prior written notice if the delay or default of the other party due to any
     of the above-mentioned causes continues for a period of six (6) months.
     Each party will give the other party prompt written notice of any such
     condition likely to cause any delay or default.

j.   Freedom of Action. This MTA and the Statements of Work will not prevent
     -----------------
     either party from (i) entering into any agreement similar to this MTA or
     any Statement of Work with any corporation in any industry or any non-
     profit body such as a university or a government, or (ii) developing,
     manufacturing and/or selling any product or service that can compete with
     the other party's products or services in the marketplace.

k.   Intellectual Property Indemnity.
     -------------------------------

     (1)   If, under a Statement of Work, one party ("Licensor") transfers
           Materials, whether its own or those of a third party, to the other
           party ("Licensee"), the Licensor, except as otherwise provided below,
           will defend or settle any claim made or any suit or proceeding
           brought against the Licensee so far as its is based on an allegation
           that any Materials furnished under the Statement of Work infringes a
           patent or copyright of the country in which

                 the Licensee takes delivery of the product (or the country in
                 which an end-user takes delivery of the product), if the
                 Licensor is notified promptly in writing and is given
                 information, assistance and the sole authority to defend or
                 settle same at the Licensor's expense. The Licensor will pay
                 all damages and costs finally awarded therein against the
                 Licensee. In addition, GlobalTel agrees that it will indemnify
                 Novell, and hold it harmless, from any action based on an
                 allegation that any Materials, provided by an entity other than
                 Novell, that are provided by GlobalTel in connection with
                 GlobalTel's offering, infringe a patent or copyright of the
                 country in which an end user takes delivery of the Materials.
                 Moreover, GlobalTel agrees that it will pay Novell's reasonable
                 attorney's fees incurred in connection with any such action.

           (2)   In case the Materials in such suit are held to infringe and use
                 of the Materials are enjoined or the case is settled, as
                 referred to above, the Licensor will have the option, at its
                 expense, to procure for the Licensee the right to continue
                 using the Materials, to replace or modify such Materials so
                 that they become non-infringing materials which have the same
                 or additional functionality and comparable or better
                 performance characteristics, or to terminate the license with
                 respect to the Materials that are infringing.

           (3)   The Licensor will have no liability for any infringement of
                 patents, copyrights, trademarks or other intellectual property
                 rights that result from (a) the Licensor's compliance with the
                 Licensee's designs, specifications, or instructions, (b)
                 modifications of the Materials that were not requested or
                 authorized by the Licensor, (c) use of the Materials other than
                 as specified in relevant Licensor publications, (d) use of the
                 Materials with goods not supplied by the Licensor, or (e) the
                 furnishing of any intangible information, service or technical
                 support to the Licensee.

           (4)   This Section 9.k will represent the entire and exclusive
                 obligation of one party to the other regarding any claim of
                 intellectual property infringement arising under a Statement of
                 Work, except as explicitly stated otherwise in the Statement of
                 Work.

           (5)   This Section 9.k is subject to the provisions of Section 9.n 
                 below.

     i.    Independent Contractors. Each party is and will remain an independent
           -----------------------
           contractor with respect to all performance under this MTA and the
           Statements of Work. No employee of either party will be considered an
           employee or agent of the other party for any purpose. Each party
           assumes sole responsibility for the supervision, daily direction and

                  10.1.1.1   In all cases under this Service Platform SOW in 
                  which GlobalTel consults with Novell or otherwise obtains
                  Novell's input or assistance, GlobalTel will in good faith

                 10.1.1.2 Statements of a party's intent in this Service
                 Platform SOW reflect that party's good faith intent as of the
                 Effective Date, but do not represent binding obligations of
                 that party.

                 10.1.1.3 The term "include" and its derivatives are
                 illustrative and not limiting or exclusive.

           10.1.2    Severability.  If any provision of this Service Platform 
                     ------------
           SOW will be found by a court of competent jurisdiction to be invalid
           or unenforceable, such finding will not affect the validity and/or
           enforceability of the Service Platform SOW as a whole or of any other
           part of the Service Platform SOW. In such case this Service Platform
           SOW will be construed and enforced as if it did not contain the
           invalid and/or unenforceable provision. However, if either party
           considers that provision to be an essential element of this Service
           Platform SOW, the parties agree to promptly negotiate a replacement
           achieving the same intent to the extent possible.

     10.2  Termination.
           -----------

           10.2.1    Either party may terminate this Service Platform SOW if the
           other party is in default. A party to this Service Platform SOW is in
           default if, subject to Section 10.2.2, it commits a material breach;
           or it ceases normal operations or becomes insolvent. As used in this
           Section 10.2.1, "insolvent" means that the party is unable to pay its
           debts as they become due, files or has filed against it a petition
           under an bankruptcy law (which, if involuntary, is unresolved after
           60 calendar days), proposes any dissolution, liquidation,
           composition, financial reorganization, or recapitalization with
           creditors, makes an assignment or trust mortgage for the benefit of
           creditors, or that a receiver trustee, custodian, or similar agent is
           appointed or takes possession with respect to any major property or
           business of that party.

           10.2.2    If a material breach of this Service Platform SOW will be
           claimed to have occurred by either party, that party will give the
           violating party Formal Notice stating the nature of the violation
           with reasonable particularity. Termination will not become effective
           unless the violating party will have failed to cure or correct the
           violation within 90 days of the receipt of such notice.

           10.2.3    Upon expiration or termination of this Service Platform SOW
           for any reason, each party will, at the request of the other party,
           return and make no further use of property, Materials, and other
           items (and all copies thereof) belonging to the other party and
           relating to this Service Platform SOW.

     10.3  Survival of Obligations. The obligations of the parties under this

           Workers' Compensation or similar acts made by persons furnished by
           Employer or by an subcontractor, or by reason of any injuries to such
           persons for which Indemnitee would be responsible under Workers'
           Compensation or similar acts if the persons were employed by
           Indemnitee, (3) any failure on the part of Employer to satisfy all
           claims for labor, equipment, materials, and other obligations

           Employer agrees, at its expense, to defend Indemnitee, at
           Indemnitee's request, against any such claim, demand, or suit.
           Indemnitee agrees to notify Employer within a reasonable time of any
           written claims or demands against Indemnitee for which Employer is
           liable under this Section 11.2.1.

           11.2.2  Employer will not implead or bring any action against the
           other party or its employees based on any claim by a person for
           personal injury or death that

     amended, or any state securities law. It may not be sold or otherwise
     transferred unless registered under applicable federal or state securities
     laws or the Company issuing the stock is furnished with an opinion of
     counsel acceptable to it that an exemption from registration is available.
     This stock is also subject to certain restrictions set forth in a
     shareholders' agreement or the bylaws of GlobalTel Resources, Inc., and may
     not be sold or transferred except in compliance therewith.

     After Closing, transfer of shares in Purchaser shall be restricted by a
provision in Purchaser's Bylaws or Articles of Incorporation consistent with the

6.   OWNERSHIP OF WORKS CREATED BY EMPLOYEE.  The Employee acknowledges that the
Corporation shall have exclusive ownership of all inventions, technology and
know-how that the Employee creates or modifies during the term of this Agreement
and any subsequent agreement.  The Corporation shall have the exclusive
copyright rights in such works and related materials and shall be considered the
author and owner of any such copyrightable work created by the Employee during
the term of this Agreement, as authorship is defined in the Copyright Act, 17
U.S.C. (S) 102.  All such work shall be considered "work made for hire" under 17
U.S.C. 201(b).  To the extent that any such work does not qualify as a "work
made for Hire" under applicable law, the Employee hereby irrevocably and
exclusively assigns to the Corporation, its successors and assigns all right,
title and interest in and to such work, including the right to copyright,
patent, trade secret, and other proprietary rights protection.  To the extent
that any of the Employee's rights in such a work are not, or may not be, subject
to assignment or transfer, or the Employee may have a right of avoidance as to
any such assignment or transfer, the Employee hereby irrevocably and
unconditionally waives enforcement of all such rights, including moral rights.
The Employee acknowledges that the transfer, assignment and waiver of the

section resides exclusively with the Corporation.

7.   TERMINATION.  This Agreement may be terminated by either party upon 30 days
written notice, if for cause, and upon 180 days advance written notice, if
without cause.  The term "cause" means any material breach of the Employee's
duty of loyalty to the Corporation; material failure to perform his Corporate
duties for a period of 30 days on a consistent basis after written notice of
such failure, regardless of the cause; any failure to carry out a lawful order
of the Board, or for any fact of documented material corporate misconduct,
fraud, or criminal malfeasance.

     Termination of this Agreement for cause shall automatically terminate for
cause all other agreements between the Corporation or its subsidiary and the
Employee.  In the event of "for-cause" termination, the employee would forfeit
any right to additional stock grants or ISOP awards not yet vested or exercised,
or the payment of salary or benefits beyond the effective contract three year
date, together with any continuing Board representation.

     The Company shall retain the right to terminate the Employee without cause,
so long as the Company honors the balance of the compensation (cash, benefits,
stock or other compensation elements specified in the Employee's contract) under
the full term of this Agreement as provided for under this agreement.  The scope
and enforceability of this section shall be determined in accordance with
Washington law.

     In the event that the Corporation establishes the Employee's breach or
threatened breach of this section's provisions, the Corporation shall be
entitled to any injunction restraining the Employee from disclosing any
Proprietary Trade Secrets or Customer Confidences and/or restraining the
Employee from rendering any services to any person, firm, corporation,
association or other entity to whom any Proprietary Trade Secret or Customer
Confidence, in whole or in part, either has been disclosed or is threatened to
be disclosed.

     Nothing contained in this section shall be construed as prohibiting the
Corporation from pursuing any other remedies available to the Corporation for
breach or threatened breach of this provision, including the recovery of damages
from the Employee, as well as reasonable attorneys fees and costs.

                                                                               3

8.   CHANGE OF CONTROL EVENT.  Should the Company (or its successor GTR) undergo
a change of control event, including acquisition of a 50% or larger controlling
interest, sale of the Company (excluding an initial acquisition of GFP by GTR)
or its principal assets, the Employee shall, as an obligation of the acquirer,
have the right to receive an additional three years cash compensation and
continuation of benefits beyond the stated contract period (including a bonus
which represents the sum of the prior two years bonus, or an equivalent amount
if less than two years of employment in service has been gained).

9.   DISPUTES/ARBITRATION.  Any controversy or claim arising out of or relating
to this Agreement, or a breach hereof, shall be settled by binding arbitration
under the Judicial Arbitration Management Services ("JAMS") conducted in
accordance with the then existing Washington Civil Court rules and judgment upon
the award rendered by the arbitrator may be entered in any court having
jurisdiction thereof.  The losing or substantially non-prevailing party shall
pay the JAMS arbitration and private counsel attorney fees and reasonable costs
to the winning or substantially prevailing party in the event of such
arbitration.

10.  ASSIGNMENT.  This Agreement shall not be transferred or assigned whether
voluntarily or by operation of law without the written consent of the other
party, with the exception of an acquisition of the Company or its principal
assets by GTR under any sale/purchase agreement, wherein the assignment of the
contractual obligations to GTR becomes automatic.

11.  WAIVER.  No waiver of any of the provisions hereof shall be valid unless in
writing, signed by the party against whom such claim or waiver is sought be
enforced, nor shall failure to enforce any right hereunder constitute a
continuing waiver of the same or a waiver of any other right hereunder.

12.  NON-COMPETITION.  Employee agrees not to compete with the Company (or its
successor, following its acquisition by GTR) for a period of two years from the
date of termination in the same or similar business, including the attempt to
develop other telecom business from SCITOR/SITA, should the employee be
terminated for cause.

     Such non-competition covenant shall include a restriction on the Employee
as of the termination date preventing the Employee from:  soliciting business
from any customer of the Company of a similar type; or soliciting business from
any customer of management-level employees of the Company to leave the
Corporation's employment or hire any management employee of the Company.  Should
the employee be terminated not for cause or leave employment voluntarily, this
non-competition covenant shall survive for twelve months from the date of
termination, with the ability of the Employee to conduct any business with
customers of the Company based upon a written request approved in writing by the
Board of Directors detailing how the business arrangement does not conflict with
the Company's business.  The Company shall be entitled to an injunction
restraining the Employee from any action which represents a breach or threatened
breach of this provision.  Nothing in this section shall be construed as
prohibiting the Corporation from pursuing any other available remedies for the
breach or threatened breach, including the recovery of damages from the
Employee, as well as reasonable attorneys fees and costs.

13.  AMENDMENT.  No modification of any of the provisions hereof shall be
binding upon either Employee or Company, unless in writing, signed by the party
against whom such modification is sought to be enforced.  Amendments upon merger
with GTR shall not be binding unless agreed to in writing by the Employee.

14.  APPLICABLE LAW.  This agreement shall be governed by the laws of the State
of Washington.

                                                                               4

fully sets forth their entire agreement concerning terms and conditions of the
employment agreement between them.

7. TERMINATION. This Agreement may be terminated by either party upon 30 days
written notice, if for cause, and upon 180 days advance written notice, if
without cause. The term "cause" means any material breach of the Employee's duty
of loyalty to the Corporation; material failure to perform his corporate duties
for a period of 30 days on a consistent basis after written notice of such
failure, regardless of the cause; any failure to carry out a lawful order of the
CEO, or for any fact of documented material corporate misconduct, fraud, or
criminal malfeasance. Termination of this Agreement for cause shall
automatically terminate for cause all other agreements between the Corporation
or its subsidiary and the Employee. In the event of "for-cause" termination, the
employee would forfeit any right to additional stock grants or ISOP stock awards
not yet vested or exercised, or the payment of salary or benefits beyond the
effective contract three year date, together with any continuing Board
representation.

          The Company shall retain the right to terminate the Employee without
cause, so long as the Company honors the balance of the compensation (cash,
benefits, stock or other compensation elements specified in the Employee's
contract) under the full term of this Agreement as provided for under this
agreement.  The scope and enforceability of this section shall be determined in
accordance with Washington law.

          In the event that the Corporation establishes the Employee's breach or
threatened breach of this section's provisions, the Corporation shall be
entitled to an injunction restraining the Employee for disclosing any
Proprietary Trade Secrets or Customer Confidences and/or restraining the
Employee from rendering any services to any person, firm, corporation,
association or other entity to whom any Proprietary Trade Secret or Customer
Confidence, in whole or in part, either has been disclosed or is threatened to
be disclosed.
                                                                               3

          Nothing contained in this section shall be construed as prohibiting
the Corporation from pursuing any other remedies available to the Corporation
for breach or threatened breach of this provision, including the recovery of
damages from the Employee, as well as reasonable attorneys fees and costs.

8. CHANGE OF CONTROL EVENT. Should the Company (or its successor GTR) undergo a
change of control event, including acquisition of a 50% or larger controlling
interest, sale of the Company (excluding an initial acquisition by GTR) or its
principal assets, the Employee shall, as an obligation of the acquirer, have the
right to receive an additional three years cash compensation and benefits beyond
the stated contract period (including a bonus which represents the sum of the
prior two years bonus, or an equivalent amount if less than two years of
employment in service has been gained).

9. DISPUTES/ARBITRATION. Any controversy or claim arising out of or relating to
this Agreement, or a breach hereof, shall be settled by binding arbitration
under the Judicial Arbitration Management Service ("JAMS") conducted in
accordance with the then existing Washington Civil Court rules and judgment upon
the award rendered by the arbitrator may be entered in any court having
jurisdiction thereof. The losing or substantially non-prevailing party shall pay
the JAMS arbitration and private counsel attorney fees and reasonable costs to
the winning or substantially prevailing party in the event of such arbitration.

10. ASSIGNMENT. This Agreement shall not be transferred or assigned whether
voluntarily or by operation of law without the written consent of the other
party, with the exception of an acquisition of the Company or its principal
assets by GTR under any sale/purchase agreement, wherein the assignment of the
contractual obligations to GTR becomes automatic.

11. WAIVER. No waiver of any of the provisions hereof shall be valid unless in
writing, signed by the party against whom such claim or waiver is sought to be
enforced, nor shall failure to enforce any right hereunder constitute a
continuing waiver of the same or a waiver of any other right hereunder.

12. NON-COMPETITION. Employee agrees not to compete with the Company (or its
successor, following its acquisition by GTR) for a period of two years from the
date of termination in the same or similar business, including the attempt to
develop other telecom business from SCITOR/SITA, should the employee be
terminated for cause. Such non-competition covenant shall include a restriction
on the Employee as of the termination date preventing the Employee from:
soliciting business from any customer of the Company of a similar type; or
soliciting, recruiting or attempting to induce any management-level employees of
the Company to leave the Corporation's employment or hire any management
employee of the Company.

          Should the employee be terminated not for cause or leave employment
voluntarily, this non-competition covenant shall survive for twelve months from
the date of termination, with the ability of the Employee to conduct any
business with customers of the Company based upon a written request approved in
writing by the Board of Directors detailing how the business arrangement does
not conflict with the Company's business.

          The Company shall be entitled to an injunction restraining the
Employee from any action which represents a breach or a threatened breach of
this provision.  Nothing in this section shall be construed as prohibiting the
Corporation from pursuing any other available remedies for the breach or
threatened breach, including the recovery of damages from the Employee, as well
as reasonable attorneys fees and costs.
                                                                               4

13. AMENDMENT. No modification of any of the provisions hereof shall be binding
upon either Employee or Company, unless in writing, signed by the party against
whom such modification is sought to be enforced. Amendments upon merger with GTR
shall not be binding unless agreed to in writing by the Employee.

14. APPLICABLE LAW. This agreement shall be governed by the laws of the State of
Washington.

15. NOTICE. Any notice required or desired to be given under this Agreement
shall be sufficient if in writing and sent by certified mail, return receipt
requested, to the Employee's residence or to the principal office of the
Corporation, as the case may be.

16. COMPLETE AGREEMENT. The parties understand and agree that this Agreement
fully sets forth their entire agreement concerning terms and conditions of the
employment agreement between them.

          IN WITNESS WHEREOF, the parties have agreed to the content of this
Agreement, and have executed and entered into this Agreement on the date set
forth above.

must request written consent of the Corporation's Board of Directors to engage
in any such outside business activity which writing shall specify the outside
business activity in detail, and shall be attached to this Agreement. As to any
request for consent, the Board of Directors shall not unreasonably withhold
consent, taking into account the nature of the outside business activity, its
relationship to the Corporation's business, the relative time that the Employee

would have an adverse impact on the Corporation's business. The Corporation has

service or product of the Corporation. The Employee may invest the Employee's
assets without restriction so long as the investment does not require the

for hire" under 17 U.S.C. (S) 201(b).  To the extent that any such work does not

assigns all right, title and interest in and to such work, including the right
to copyright, patent, trade secret, and other proprietary rights protection.  To

be, subject to assignment or transfer, or the Employee may have a right of
avoidance as to any such assignment or transfer, the Employee hereby irrevocably
and unconditionally waives enforcement of all such rights, including moral
rights.  The Employee acknowledges that the transfer, assignment, and waiver of
the foregoing rights and interests are complete and effective as of the date of

and execution of this Agreement and without regard to the time or circumstances
under which the Agreement may be terminated.  The Employee agrees to execute any
assignments or other documents and take such other actions as may be necessary

actual or demonstrably anticipated research or development at the time the
software is created and does not result from any work performed by the Employee

technology, work in progress, know-how, techniques, and current and anticipated

threatened breach of this section's provisions, the Corporation shall be
entitled to an injunction restraining the Employee from disclosing any
Proprietary Trade Secrets or Customer Confidences and/or restraining the
Employee from rendering any services to any person, firm, corporation,
association or other entity to whom any Proprietary Trade Secret or Customer

recovery of damages from the Employee, as well as reasonable attorneys fees and
costs.

competing or conflicting part of the outside business into the Corporation for
its fair market value on mutually agreed terms, permit the Corporation to
acquire the competing or conflicting portion of the employee's business for its
fair market value on mutually agreed terms, or terminate employment with the
Corporation.  After termination of this Agreement for any reason, the Employee-
may request written consent from the Corporation's Board of Directors to permit
the Employee to become associated with a competitor prior to expiration of the
12-month period stated above.  The Board of Directors shall not unreasonably
withhold consent and shall base any denial of consent upon its determination
that the former Employee's requested business activity would significantly
impair the Corporation's operations, market position, proposals in progress, or
relationship with existing customer(s).  In the event that the Corporation
establishes the Employee's actual or threatened breach of this section's
provisions, the Corporation shall be entitled to an injunction restraining the
Employee from the action or threatened action.  Nothing in this section shall be
construed as prohibiting the Corporation from pursuing any other available
remedies for the breach or threatened breach, including the recovery of damages
from the Employee, as well as reasonable attorneys fees and costs.

          18.  Arbitration.  Any controversy or claim arising out of, or
               -----------                                              
relating to, the meaning or enforceability of any provision of this Agreement,
the terms of employment, the work performed by the Employee, or ownership of any
product or right created during or after the terms of this Agreement, shall be
settled by binding arbitration before a single arbitrator of the Judicial
Arbitration and Mediation Service in the city of Seattle, Washington, or as
agreed-upon by the parties or selected by the King County Presiding Judge.  The
arbitration shall be conducted in accordance with the then existing Washington
Civil Court Rules and judgment upon the award shall be rendered within six
months of commencement of arbitration, if practicable, and shall be final and
enforceable in any court of competent jurisdiction.

          19.  Attorneys Fees.  In the event of any dispute arising out of this
               --------------                                                  
Agreement or the employment relationship, the substantially prevailing party in
such dispute shall be entitled, in addition to any other relief, to an award of
attorneys fees and actual costs, including expert fees and arbitration fees.
The award shall include fees and costs incurred before any proceeding or
arbitration is commenced.  If a proceeding is commenced and neither party wholly
prevails, the party receiving substantially greater relief shall be considered
the prevailing party as to all fees and costs relating to the dispute.  The
actual attorneys fees and costs incurred by the substantially prevailing- party
shall be presumptively reasonable, which presumption is rebuttable.

          20.  Notices.  Any notice required or desired to be given under this
               -------                                                        
Agreement shall be sufficient if in writing and sent by certified mail, return
receipt requested, to the Employee's residence or to the principal office of the
Corporation, as the case may be.

               ----------------                                              
Employee of a breach of any provision of this Agreement shall not operate or be
construed as a waiver of any subsequent breach by either the Corporation or the
Employee.

          22.  Assignment. Sale or Merger.  The Employee acknowledges that the
               --------------------------                                     
services to be rendered by him or her are unique and personal.  Accordingly, the
Employee may not assign any of his or her rights or delegate any of his or her
duties or obligations under this Agreement.  The rights and obligations of the
Corporation under this Agreement shall inure to the benefit of, and shall be
binding upon, the successors and assigns of the Corporation.  The parties
contemplate and intend that this Agreement shall be assumed without material
change by GlobalTel as part of its acquisition of GFP Group and that it will be
fully enforceable by GlobalTel and the Employee without the need of any
additional agreement.  In the event of a sale or merger of the Corporation to
any other entity, the successor to the Corporation shall assume the
Corporation's obligations pursuant to this Agreement.  In the event that a sale,
merger or corporate restructure results in a 50 percent or greater change of
ownership or control of the Corporation's affairs, except as a result of the
GlobalTel acquisition, the Employee may terminate this Agreement and require
that the Corporation redeem the Employees stock pursuant to the formula and
method of valuation stated in the Shareholder Agreement, and pay the other
amounts as provided in paragraph 14 above.

this Agreement and signed by the parties contain the entire agreement of the
parties.  There are no other agreements, oral or written.  This Agreement may be
changed only by a written agreement signed by the party against whom enforcement
is sought.  In the event of a conflicts the terms of more recently executed
documents supersede those of earlier documents.

          24.  Severability.  The provisions of Section 5 "Extent of Service,"
               ------------

Services; Accounting and Disclosure of Income and Unrelated Software," Section
15 "Conflict of Interest," Section 16 "Proprietary Information," Section 17
"Restrictive Covenant," and any addendum that concerns the subject matter of any
of those provisions, state obligations of the parties that are independent of
each other, severable, and separately enforceable.  To the extent that any
portion of a provision is deemed unenforceable, the balance of that provision
shall be fully enforced.  The unenforceability of any provision shall have no
effect on the enforceability of any other provision of this Agreement.

          25.   Applicable Law.  This Agreement shall be construed in accordance
                --------------

(the "Employee") and GFP GROUP, INC., a Washington corporation (the
"Corporation"), in consideration of the mutual covenants and conditions
contained in this Agreement, agree as follows:

          1.  Employment.  The Corporation hereby employs the Employee and the
              ----------                                                      
Employee hereby accepts employment upon the terms and conditions set forth in
this Agreement.

          2.  Term.  The term of this Agreement shall begin on the effective
              ----                                                          
date set forth above and shall continue on a rolling  three year term, renewing
daily.  The parties acknowledge the Corporation's intention to be acquired by
GlobalTel Resources, Inc. ("GlobalTel") in a manner that will require that
GlobalTel assume the Corporation's obligations pursuant to this Agreement, in
which case GlobalTel will automatically assume GFP Group's rights and
obligations and the term of this Agreement shall continue without requiring any
action by either party, or GlobalTel.

          3.  Compensation. For all services rendered by the Employee under this
              ------------                                                      
Agreement, the Corporation shall compensate the Employee as determined by the
Board of Directors.  The Employee shall receive a one-time payment of $10,000,
half on execution of this Agreement and half on completion of GlobalTel's
Acquisition of GFP Group.  Starting compensation of $5,000 per month.
Compensation shall be increased to $10,000 per month on the earlier of -March 1,
1996 or receipt of significant institutional funding for operations.
Compensation shall be increased to a minimum of $12,500 per month at the
beginning of the second year of employment and to $15,000 per month at the
beginning of the third year of employment.  The Corporation and the Employee
contemplate significant increases in salary and benefits if target goals for
corporate financing and expansion are met.  Employee shall receive increases in
compensation equal to any increases in the compensation of the Corporation's
other comparable officers, currently Curtis Lew and Alan Chin.  Compensation may
also be increased in the discretion of the Board of Directors and additional
bonuses may be paid to the Employee at the discretion of the Board of Directors.

          4.  Duties.  The Corporation employs the Employee as Vice President to
              ------                                                            
perform work in connection with marketing, sales, network operations or such
other projects or products that are being undertaken by the Corporation, as
directed by the President of the Corporation.  The Employee shall also continue
duties as an officer of the Corporation's GFP Group  subsidiary, including
administration of the SITA/SCITOR Agreement.  The employee shall report directly
to the Chief Executive Officer of the 

                                       1
<PAGE>
 
Corporation. Any duties of the Employee as a director or an officer of the
Corporation shall be without further compensation.

          5.  Extent Of Service.  The Employee shall devote his or her time,
              -----------------                                             
attention and energies to the Corporation's business on a full time basis,
unless a different basis is provided in an addendum to this Agreement, and shall
not become involved in any other business activity that would in any way detract
from, limit, or impair the Employee's performance of his work for the
Corporation or may adversely impact the Corporation's business interests,
whether or not such outside business activity is pursued for gain, profit, or
other pecuniary advantage.  The Employee must request written consent of the
Corporation's Board of Directors to engage in any such outside business activity
which writing shall specify the outside business activity in detail, and shall
be attached to this Agreement.  As to any request for consent, the Board of
Directors shall not unreasonably withhold consent, taking into account the
nature of the outside business activity, its relationship to the Corporation's
business, the relative time that the Employee would be required to devote to the
Corporation's business and to the outside business activity, and whether the
effect on the Employee's work performance would have an adverse impact on the
Corporation's business.  The Corporation has no obligation to consent to an
outside business activity that, in its sole opinion, could adversely impact
conduct of the Corporation's business.  The Corporation may condition consent
upon a reasonable compensation adjustment reflecting the impact on the
Corporation.  The Corporation acknowledges that the Employee operated a
consulting business prior to becoming an employee and agrees that the Employee
may continue to service existing customers described in Exhibit A for a
transition period of six months.  The Employee represents that time devoted to
such consulting work shall not prevent him from working full time for the
Corporation and that such work shall not be in competition with any service or
product of the Corporation.  The Employee may invest the Employee's assets
without restriction so long as the investment does not require the Employee to
devote his or her services to operation of the companies in which the
investments are made and so long as the subject of the investment is not
inconsistent with the Corporation's business interests.

          6.  Ownership of Works Created By Employee.  The Employee acknowledges
              --------------------------------------                            
that the Corporation shall have exclusive ownership of all inventions,
technology, and know-how that the Employee creates or modifies during the term
of this Agreement and any previous agreement.  The Corporation shall have the
exclusive copyright rights in such, works and related materials and shall be
considered the author and owner of any such copyrightable work created by the
Employee during the term of this Agreement, as authorship is defined in the
Copyright Act, 17 U.S.C. (S) 102.  All such work shall be considered "work made
for hire" under 17 U.S.C. (S) 201(b).  To the extent that any such work does not
qualify as a "work made for hire" under applicable law, the Employee hereby
irrevocably and exclusively assigns to the Corporation, its successors and
assigns all right, title, and interest in and to such work, including the right
to copyright, patent, trade secret, and other proprietary rights protection.  To
the extent that any of the 

                                       2
<PAGE>
 
Employee's rights in such a work are not, or may not be, subject to assignment
or transfer, or the Employee may have a right of avoidance as to any such
assignment or transfer, the Employee hereby irrevocably and unconditionally
waives enforcement of all such rights, including moral rights. The Employee
acknowledges that the transfer, assignment, and waiver of the foregoing rights
and interests are complete and effective as of the date of this Agreement in
consideration of the Corporation's employment of the Employee and execution of
this Agreement and without regard to the time or circumstances under which the
Agreement may be terminated. The Employee agrees to execute any assignments or
other documents and take such other actions as may be necessary or desirable to
assure or verify that ownership of the rights addressed in this section resides
exclusively with the Corporation.

          7.  Ownership Of Unrelated Works.  The Corporation's ownership of
              ----------------------------                                 
works created by the Employee during the term of this Agreement shall not apply
to Unrelated Works, which is defined as a work that is not created through the
use of any of the Corporation's equipment, supplies, facilities, or trade secret
information, which was developed entirely on the Employee's own time and which
does not relate directly to the Corporation's business or the Corporation's
actual or demonstrably anticipated research or development at the time the
software is created and does not result from any work performed by the Employee
for the Corporation.  The Employee's development of Unrelated Works shall not
limit the Corporation's business or prohibit the Corporation from developing
similar or related works.  Should all or part of the Employee's Unrelated Work
be incorporated into the Corporation's inventions or other works, the
Corporation shall have a royalty-free license to copy, use, and sell such works
without restriction, unless the Employee and the Corporation have executed a
written agreement providing otherwise in advance of such incorporation, or the
Employee establishes that the Corporation wrongfully obtained the Unrelated
Works through no fault of the Employee.

          8.  Fringe Benefits.  The relationship between the Corporation and the
              ---------------                                                   
Employee is that of an employer and employee.  The parties acknowledge that the
nature of the Employee's work requires substantial technological expertise and
the consistent exercise of substantial discretion and judgment.  The Employee is
a professional, salaried, full-time employee who shall be entitled to
participate in the Senior Management Benefit Package.  "Senior Management
Benefit Package" means the retirement, ISOP, bonus, expense allowance, profit
sharing, vacation, and similar plans adopted by the Corporation for the
President and Vice-Presidents having the same full-time status and length of
service as the Employee.  The Corporation anticipates having the package in
place within six months after execution of this Agreement.

          9.  Income From Services; Accounting And Disclosure Of Income And
              -------------------------------------------------------------
Unrelated Software.  Income generated by the Employee from the creation,
- ------------------                                                      
maintenance, or modification, use, license, sale, or any other transfer of
Unrelated Works, and from outside business activities permitted by this
Agreement shall belong to the Employee.  

                                       3
<PAGE>
 
While employed by the Corporation and for three years thereafter, the Employee
agrees upon request of the Corporation to render a true account of all
information and transactions concerning Unrelated Works and/or outside business
activities should the Corporation receive information reasonably suggesting that
the such Works or outside business activity violates the terms of this
Agreement. The Corporation shall require that those employees and agents of the
Corporation having access to this information shall keep confidential all
information disclosed pursuant to this section and the Corporation shall limit
access to such information to the members of the Board of Directors and the
management-level employee conducting the accounting.

          10.  Working Facilities.  The Corporation will furnish the Employee
               ------------------                                            
with working space, hardware, technical and secretarial assistance, and other
facilities and services suitable to Employee's position and adequate for the
performance of the Employee's duties.  Any automobile allowance or payment of
relocation expenses shall be as provided in the Senior Management Benefit
Package.  The Corporation shall provide the Employee with an office in Los
Angeles, California, near the SCITOR switch facility.  The Employee shall have a
full time administrative assistant in the Los Angeles office.

          11.  Expenses.  The Corporation shall pay for or reimburse the
               --------                                                 
Employee for travel, lodging, and all reasonable and necessary expenses for the
promotion of the business of the Corporation, including expenses for
entertainment, dues, and other expenses that the Employee reasonably and
necessarily incurs in the performance of the duties for the Corporation covered
by this Agreement.

          12.  Vacations.  The Employee shall be entitled each calendar year to
               ---------                                                       
a vacation consisting of two two-week periods, which may be increased by the
Corporation's business and subject to any policies adopted prospectively by the
Board of Directors, during which time the Employee's salary shall be paid in
full.  The Employee may carry over no more than one two-week period to the next
calendar year (for a total of six weeks).  The Employee shall take the vacation
at such time or times as shall be approved by the Corporation.  Vacation time
may not be accrued from year to year without the advance written consent of the
Corporation, but the Corporation shall pay the Employee for any vacation days
lost.

               ----------------                                                
may be granted to the Employee for attendance at professional conventions,
seminars, and other professional or business activities approved by the
Corporation.  All expenses reasonably and necessarily incurred by the employee
in these activities shall be paid for or reimbursed by the Corporation.  The
Corporation may from time to time approve leaves of absence with full or partial
payment of salary and other expenses for other reasons in its sole discretion.

               -----------                                                   
upon 30 days written notice, if for cause, and upon 60 days advance written
notice, if without' cause.  The term "cause" means any material breach of the
employee's duty of loyalty to the Corporation; material failure to perform his
corporate duties for a period of 30 days on a consistent basis after written
notice of such failure, regardless of the cause; any act of criminal fraud,
whether or not involving the Corporation; or any material breach of the terms of
this Agreement, the Acquisition and Management Agreement, Shareholder Agreement,
or any other written agreement between the Employee and the Corporation or its
subsidiary, GFP Group, Inc.  Termination of this Agreement for cause shall
automatically terminate for cause all other agreements between the Corporation
or its subsidiary and the Employee.  In the case of termination for cause,
unless the Employee contests the grounds stated in the notice and demands
arbitration, all rights of the Employee under such agreements and all rights
under this Agreement, including salary, benefits, and Board representation shall
automatically be extinguished as of the termination date stated in the notice
and the Employee's stock, including vested options, shall be redeemed by the
Corporation at 75 per cent of the value calculated pursuant to the method stated
in the shareholder agreement, so long as the Corporation's stock is not then
publicly traded, in which case there shall be no redemption.  If the Employee
demands arbitration of the termination grounds, the parties will immediately
proceed to arbitration and all compensation, benefits, and stock voting rights
of the Employee shall be suspended pending the decision of the arbitrator, which
shall take place within six months from the commencement of arbitration unless
delay is caused by the Employee.  If the Corporation terminates this Agreement
without cause, the Corporation shall be obligated to continue to provide the
Employee with the full salary and compensation benefits required by this
Agreement until the expiration of the rolling three-year term.  Unless the
Corporation's stock is then publicly traded, the Corporation shall redeem the
Employee's stock, including vested options, at market value determined by the
method stated in the Shareholder Agreement.  All stock acquisition rights shall
cease as of the termination date stated in the written notice of termination,
whether the stock is publicly traded or not.  Unless otherwise agreed, the
redemption amount shall be paid as follows: in 12 equal monthly installments if
the amount is less than $500,000; in 24 equal monthly installments if the
redemption amount is between $500,000 and $1,000,000  and in equal quarterly
installments over a five-year period if the redemption amount is $1,000,000 or
more.  Each installment shall include interest on the declining balance at 6%
per annum, compounded monthly.

          15.  Conflict Of Interest.  Except as provided in Section 5, above,
               --------------------                                          
the Employee warrants and represents that:  (1) the Employee has no conflict of
interest in performing the duties for which the Corporation is hiring the
Employee; (2) that the Employee is not under any legal disability regarding
these duties and is not prohibited by any employment agreement or covenant not
to compete from performing these duties; (3) that the work the Employee is
performing and will perform for the Corporation does not to the knowledge of the
Employee, breach any contract or infringe upon any existing patent or copyright
or 

                                       5
<PAGE>
 
contain any proprietary information or trade secrets of any former employer or
other person or entity.

          16.  Proprietary Information. The Employee acknowledges that the list
               -----------------------                                         
of Corporation's contracts, suppliers, customers, material information on the
business of those customers, and the Corporation's telecommunication technology,
work in progress,' know-how, techniques, and current and anticipated research
and development activities, as well as the related printed and tangible
materials, as these may exist from time to time, constitute Proprietary Trade
Secrets of the Corporation that are valuable, special and unique assets of the
Corporation's business and which the Corporation takes reasonable steps to
safeguard from disclosure to persons that do not owe a duty of confidentiality
to the Corporation.  The Employee also acknowledges that conducting the
Employee's duties for Corporation's business may require that the Employee come
into contact with information belonging to the Corporation's customers which
information is disclosed to the Employee pursuant to the Corporation's agreement
to keep the information confidential ("Customer Confidences").  The employee
will not, during or after the term of employment, disclose any Proprietary Trade
Secrets or Customer Confidences, directly or indirectly, in whole or in part, to
any person, firm, corporation, association, or other entity for any reason or
purpose whatsoever.  Nor shall the Employee include any know-how, or techniques
that constitute Proprietary Trade Secrets of the Corporation or Customer
Confidences, in any invention or work unless it is owned by the Corporation.
Information shall cease being Proprietary Trade Secrets or Customer Confidences
if the Corporation or the Customer has permitted the information to enter the
public domain without any involvement of the Employee.  The scope and
enforceability of this section shall be determined in accordance with Washington
law.  In the event that the Corporation establishes the Employee's breach or
threatened breach of this section's provisions, the Corporation shall be
entitled to an injunction restraining the Employee from disclosing any
Proprietary Trade Secrets or Customer Confidences and/or restraining the
Employee from rendering any services to any person, firm, corporation,
association or other entity to whom any Proprietary Trade Secret or Customer
Confidence, in whole or in part, either has been disclosed or is threatened to
be disclosed.  Nothing contained in this section shall be construed as
prohibiting the Corporation from pursuing any other remedies available to the
Corporation for breach or threatened breach of this provision, including the
recovery of damages from the Employee, as well as reasonable attorneys fees and
costs.

          17.  Restrictive Covenant.  During the term of this Agreement and for
               --------------------                                            
a period of 12 months after termination or expiration of this Agreement, the
Employee will not (a) directly or indirectly, own, manage, operate, control, be
employed by, participate in, or be connected in any manner with any business
that derives income from providing the same or similar services or products as
those of the Corporation, or is in competition with any business that the
Corporation is conducting or demonstrably anticipates conducting as of the
Employee's termination date; (b) solicit business or perform work for any

                                       6
<PAGE>
 
customer of the Corporation, which work is similar to the type of work performed
by the Corporation for it-s customers, regardless of whether the Employee would
be performing the work on his or her own behalf or on behalf of some other
business; (c) solicit, recruit, or attempt to induce any employee to leave the
Corporation's employment or hire any employee whose employment with the
Corporation was terminated less than six months before the date of hire. If, at
any time during the term of this Agreement, the Employee's outside business
activity or Unrelated Work business conflicts with or competes with the
Corporation's then existing business, the Employee agrees either to merge the
competing or conflicting part of the outside business into the Corporation for
its fair market value on mutually agreed terms, permit the Corporation to
acquire the competing or conflicting portion of the employee's business for its
fair market value on mutually agreed terms, or terminate employment with the
Corporation. After termination of this Agreement for any reason, the Employee
may request written consent from the Corporation's Board of Directors to permit
the Employee to become associated with a competitor prior to expiration of the
12-month period stated above. The Board of Directors shall not unreasonably
withhold consent and shall base any denial of consent upon its determination
that the former Employee's requested business activity would significantly
impair the Corporation's operations, market position, proposals in progress, or
relationship with existing customer(s). In the event that the Corporation
establishes the Employee's actual or threatened breach of this section's
provisions, the Corporation shall be entitled to an injunction restraining the
Employee from the action or threatened action. Nothing in this section shall be
construed as prohibiting the Corporation from pursuing any other available
remedies for the breach or threatened breach, including the recovery of damages
from the Employee, as well as reasonable attorneys fees and costs.

          18.  Arbitration.  Any controversy or claim arising out of, or
               -----------                                              
relating to, the meaning or enforceability of any provision of this Agreement,
the terms of employment, the work performed by the Employee, or ownership of any
product or right created during or after the terms of this Agreement, shall be
settled by binding arbitration before a single arbitrator of the Judicial
Arbitration and Mediation Service in the city of Seattle, Washington, or as
agreed-upon by the parties or selected by the King County Presiding Judge.  The
arbitration shall be conducted in accordance with the then existing Washington
Civil Court Rules and judgment upon the award shall be rendered within six
months of commencement of arbitration, if practicable, and shall be final and
enforceable in any court of competent jurisdiction.

          19.  Attorneys Fees.  In the event of any dispute arising out of this
               --------------                                                  
Agreement or the employment relationship, the substantially prevailing party in
such dispute shall be entitled, in addition to any other relief, to an award of
attorneys fees and actual costs, including expert fees and arbitration fees.
The award shall include fees and costs incurred before any proceeding or
arbitration is commenced.  If a proceeding is commenced and neither party wholly
prevails, the party receiving substantially greater relief shall be considered
the prevailing party as to all fees and costs relating to the 

                                       7
<PAGE>
 
dispute. The actual attorneys fees and costs incurred by the substantially
prevailing party shall be presumptively reasonable, which presumption is
rebuttable.

               -------                                                        
Agreement shall be sufficient if in writing and sent by certified mail, return
receipt requested, to the Employee's residence or to the principal office of the
Corporation, as the case may be.

          21.  Waiver Of Breach.  The waiver by either the Corporation or the
               ----------------                                              
Employee of a breach of any provision of this Agreement shall not operate or be
construed as a waiver of any subsequent breach by either the Corporation or the
Employee.

          22.  Assignment, Sale or Merger.  The Employee acknowledges that the
               --------------------------                                     
services to be rendered by him or her are unique and personal.  Accordingly, the
Employee may not assign any of his or her rights or delegate any of his or her
duties or obligations under this Agreement.  The rights and obligations of the
Corporation under this Agreement shall inure to the benefit of, and shall be
binding upon, the successors and assigns of the Corporation.  The parties
contemplate and intend that this Agreement shall be assumed without material
change by GlobalTel as part of its acquisition of GFP Group and that it will be
fully enforceable by GlobalTel and the Employee without the need of any
additional agreement.  In the event of a sale or merger of the Corporation to
any other entity, the successor to the Corporation shall assume the
Corporation's obligations pursuant to this Agreement.  In the event that a sale,
merger or corporate restructure results in a 50 percent or greater change of
ownership or control of the Corporation's affairs, except as a result of the
GlobalTel acquisition, the Employee may terminate this Agreement and require
that the Corporation redeem the Employees stock pursuant to the formula and
method of valuation stated in the Shareholder Agreement, and pay the other
amounts as provided in paragraph 14, above.

          23.  Entire Agreement.  This Agreement and any addenda attached to
               ----------------                                             
this Agreement and signed by the parties contain the entire agreement of the
parties.  There are no other agreements, oral or written.  This Agreement may be
changed only by a written agreement signed by the party against whom enforcement
is sought.  In the event of a conflict, the terms of more recently executed
documents supersede those of earlier documents.

          24.  Severability.  The provisions of Section 5 "Extent of Service,"
               ------------

Services; Accounting and Disclosure of Income and Unrelated Software," Section
15 "Conflict of Interest," Section 16 "Proprietary Information," Section 17
"Restrictive Covenant,' and any addendum that concerns the subject matter of any
of those provisions, state obligations of the parties that are independent of
each other, severable, and separately enforceable.  To the extent that any
portion of a provision is deemed unenforceable, the 

                                       8
<PAGE>
 
balance of that provision shall be fully enforced. The unenforceability of any
provision shall have no effect on the enforceability of any other provision of
this Agreement.

          25.  Applicable Law.  This Agreement shall be construed in accordance
               --------------

                                   EXHIBIT C
 
     SECTION 4.5 - RESTRICTIONS ON SHARE TRANSFERS. Notwithstanding Section
     ---------------------------------------------                 
4.4, the shares of the corporation are restricted shares and may not be sold,
resold, assigned, pledged, gifted, or otherwise transferred (collectively
"transferred") except in full compliance with federal and state securities laws,
which may require registration of such stock or an exemption from registration.
Shares thus may not be transferred by a shareholder unless that shareholder has
first obtained written assurance from the corporation's attorney, at the expense
of the shareholder, that such sale would not violate any federal or state law or
regulation. After receiving such an assurance, the transferring shareholder may
then freely transfer shares in a transaction in which no consideration is given
or received for those shares, including without limitation transfers by bequest,
by gift, in trust for estate planning purposes, and similar transfers.

     After receiving such an assurance in the case of a sale of the shares,
if the proposed purchaser is not an existing shareholder, the selling
shareholder shall deliver to the corporation and the other shareholders an offer
in writing to sell all of those shares, at the price to be paid by the proposed
purchaser, to the corporation and the other shareholders, in that order.  The
offer shall state the name of the prospective purchaser and shall include a copy
of the corporation's counsel's opinion that no federal or state law or
regulation would be violated by such sale to the other shareholders.  The
corporation shall have ten (10) days after receipt of the offer within which to
accept or reject the offer, which may be accepted or rejected only as to all the
shares offered.

     If the corporation rejects the offer, it shall immediately so notify
the other shareholders in writing.  The other shareholders of the corporation
shall each have the right to purchase the same proportion of those offered
shares as their beneficially-owned shares bear to the beneficial ownership of
all issued and outstanding shares of the corporation, excluding those
beneficially owned by the selling shareholder.  The other shareholders shall
have thirty (30) days after receipt of notice of the corporation's rejection of
the selling shareholder's offer to accept or reject the offer, as to all of the
shares offered, by a written notice delivered to the other shareholders
including the selling shareholder.  If an individual shareholder rejects the
offer, the remaining shareholders may, within ten (10) days after receipt of
that notice, accept the offer as to that shareholder's proportionate share, in
the same proportion as their beneficial share ownership bears to the aggregate
beneficial ownerships of all shareholders electing to purchase that share.

     Unless otherwise agreed, the purchase price to be paid for shares
purchased as provided for above shall be paid within ten (10) days after
delivery of the purchaser's acceptance of the offer to sell.

     All stock certificates of the corporation will bear legends stating
the foregoing restrictions.

     SECTION 7.4 - AMENDMENTS. The Bylaws may be amended, altered or repealed,
     ------------------------                                         
at any regular or special meeting of the Board, by a vote of the majority of the
whole Board, provided that a written statement of the proposed action shall have
been delivered personally or by facsimile transmission or mailed to all
directors with the notice of the meeting. Section 4. 5 of the Bylaws may be
amended by the shareholders of the corporation only by the affirmative vote of
the holders of two-thirds (2/3) of the issued and outstanding shares of the
corporation.

     GFP Group shall immediately commence negotiations with GlobalTel for

G.   OBLIGATIONS IN CONNECTION WITH GLOBALTEL ACQUISITION.
     ---------------------------------------------------- 

     1.   GENERAL OBLIGATIONS AND CONDITIONS.  GFP Group shall structure the
          ----------------------------------                                
acquisition of GFP Group by GlobalTel so that Burtscher and Krentzman receive
the stock interest, compensation package and operational duties generally
described in this Agreement.  The primary reason for GlobalTel's interest in
acquiring GFP Group after GFP Group acquires Ratsten is to the benefit of the
SITA/SCITOR contract and the services of Burtscher and Krentzman.  The parties
to this Agreement acknowledge that the terms and conditions of the final
acquisition of GFP Group by GlobalTel have yet to be determined.  The parties,
further acknowledge that additional agreements among them, such as a Shareholder
Agreement and agreements with funding sources, will need to be prepared and
executed.  Nonetheless, the parties agree that any acquisition by GlobalTel must
meet the minimal requirements stated in this Agreement and that any material
deviation from these requirements must be agreed upon in writing by the party
adversely affected.  The parties also agree that it is GFP Group's
responsibility to conduct negotiations with GlobalTel and to obtain GlobalTel's
agreement to structure the acquisition of GFP Group to meet the requirements of
this Agreement.

     2.   BENEFITS TO KRENTZMAN AND BURTSCHER.  As part of the acquisition by
          -----------------------------------

          a.   SHARES IN GLOBALTEL.  GlobalTel shall restructure its stock so
               -------------------                                           
that there is only a single class of voting common stock.  GlobalTel shall issue
250,000 shares of GlobalTel voting common stock and enter into a binding
obligation to issue additional 

                                       2
<PAGE>
 
stock to each of Burtscher and Krentzman at the first anniversary and second
anniversary of employment with GlobalTel. Issuance of these shares shall be
sufficient to cause Krentzman and Burtscher to achieve stock parity with Alan
Chin and Curtis Lew. Stock parity includes all stock that represents an equity
interest in GlobalTel, or convertible to an equity interest, but does not
include debt instruments. The Corporation shall make financing available on
renewable terms to Krentzman and Burtscher to purchase any instruments or rights
possessed by Chin or Lew that are convertible to equity. Stock parity may be
achieved either by direct issuance of stock to Krentzman and Burtscher or
pursuant to the terms of an ISOP, or by any other means that accomplishes stock
parity. GFP Group agrees to increase its capitalization by 40,000 shares and to
issue 25,000 shares to Peter Gust and 15,000 shares to Donald Kovaks or a
nominee identified by October 31, 1995, with the parties to this Agreement
retaining the proxy rights to vote these shares until the acquisition by
GlobalTel is complete, at which time these shares shall be exchanged for a like
number of GlobalTel shares. Issuance of these shares is subject to, and
conditioned on, the shareholders: (a) executing appropriate investment letters
required by applicable securities laws and meeting the legal requirements for
investing in GFP Group or GlobalTel; (b) executing the appropriate shareholder
agreement restricting resale of such shares, voting, redemption and similar
matters; and (c) acknowledging in writing that issuance of these shares
satisfies the obligations of Krentzman and Burtscher to each of them. The
parties shall select a means that will have the least overall adverse tax impact
upon the parties as a whole. The parties shall execute a shareholder agreement
by no later than October 28, 1995 that provides in part that these stock
acquisition rights terminate, and all issued shares redeemed by the Corporation
pursuant to the valuation methods detailed in the shareholder agreement, upon
termination of employment by the employee or by GlobalTel, material breach of
the employment agreements, material failure to perform operational duties to
GlobalTel for any reason, or termination by SCITOR of the SITA/SCITOR contract,
for any reason, within 135 days from the effective date of this Agreement.

          b.   DUTIES, COMPENSATION AND EMPLOYMENT AGREEMENTS.  Krentzman and
               ----------------------------------------------

relationship with SCITOR and supervising compliance with the SITA/SCITOR
contract and GlobalTel's growth in relation to such services, under the
direction of Ronald P. Erickson, who shall become GlobalTel's President and
Chief Executive Officer.  Krentzman and Burtscher shall also alternate one of
them serving as a member of the seven-person Board of Directors of GlobalTel

agreement in substantially the form attached to this Agreement as Exhibit C-1
and C-2.  The duration of the obligations stated in this section and the term of
the employment agreements shall be a rolling three years.  Krentzman

<PAGE>
 
and Burtscher shall each, be officers of the Corporation of equal rank with Alan
Chin and Curtis Lew, who are currently vice-presidents. Their initial monthly
compensation shall equal the monthly compensation provided to Mr. Chin and Mr.
Lew. Krentzman and Burtscher shall receive the same regular retirement, health,
stock, and expense benefits ("Senior Management Benefit Package), that GlobalTel
provides to Alan Chin and Curtis Lew during, the term of the employment
agreement. This parity arrangement shall not apply to merit bonuses tied to
performance of the corporation which will be available.

          c.   LOANS FOR PRIOR RATSTEN AND PERSONAL EXPENSES.  Krentzman and
               ---------------------------------------------

acquisition has been completed and at such time as GlobalTel receives
significant institutional financing, GlobalTel shall loan Burtscher $14,500 and
shall loan Krentzman $31,500, to repay personal loans, upon presentation of
documents evidencing such loans and the outstanding balance of each.  GlobalTel
shall have the option of making payments directly to the creditors.  These loans
shall be evidenced by a note in the usual form, shall be at 6 percent per annum
interest, compounded monthly and shall be repaid by deductions from net merit or
operating bonuses payable to Krentzman or Burtscher during, the first three
years of employment.  Each loan shall be fully repaid before any portion of a
bonus is paid the employee borrowing the funds.  The loans shall not, however,
be payable from or chargeable against merit or operating bonuses earned after
the third anniversary of this Agreement.  Termination of employment at GlobalTel
for cause shall cause the entire loan balance to become due and payable in four
equal quarterly installments.  In addition to and at the same time as these
loans, GlobalTel shall pay up to an aggregate of $30,000 to repay person who
have advanced funds to Krentzman and Burtscher for Ratsten operations.  The
identities of these persons and amount that each advanced for Ratsten operations
is stated in Exhibit D to be prepared by Krentzman and Burtscher and approved by
GFP Group.  Payments shall be made directly to the persons identified in Exhibit
D upon execution of a release acknowledging that the amount paid fully satisfies
the repayment obligation of Ratsten and Burtscher or Krentzman.

obligations on termination:

          (1)  In the event that this Agreement is terminated by GFP Group

               Krentzman and Burtscher agree to reimburse GFP Group for all

               sufficient interim funding in excess of that required by this
               Agreement, if the benefit of the SITA/SCITOR contract is not
               available through no fault of Burtscher or Krentzman, or for any

                    AMENDMENT TO ACQUISITION & MANAGEMENT AGREEMENT

                                      FOR

              GFP GROUP, INC., FRANK KRENTZMAN & GERMAN BURTSCHER


          GFP Group, Inc. ("GFP Group"), Frank Krentzman ("Krentzman"), and
German Burtscher ("Burtscher") are parties to the Acquisition and Management
Agreement for GFP Group, Inc., Frank Krentzman, and German Burtscher, signed
October 10, 1995 ("A&M Agreement").  The following amendments are necessary to
conform the A&M Agreement to the intent of the parties at the time the A&M
Agreement was signed.  As the parties intended, these amendments give Krentzman
and Burtscher the bargained for shares they expected in the exchange.

          The parties agree that the A&M Agreement is amended as follows:

          1.  Krentzman and Burtscher at no cost to either shall each receive
150,000 additional shares of GlobalTel Resources, Inc. ("GlobalTel") common
stock at such time as GlobalTel receives significant funding, or other
significant developments in GlobalTel's operations and plans such that the Board
of Directors of GlobalTel deems it appropriate to issue the shares, distribution
not to be unreasonably withheld (the "date of significant funding").  The
issuance of the 150,000 shares each shall satisfy the obligation in Section E of
the A&M Agreement to issue 75,000 additional shares of GlobalTel common stock
each to Krentzman and Burtscher beginning in the second and third years of
employment with GlobalTel.

          2.  Krentzman and Burtscher shall, at the closing of the share
exchange under which GlobalTel is acquiring Krentzman and Burtscher's GFP shares
(the "closing"), receive sufficient GlobalTel shares to give Krentzman and
Burtscher the share parity with Alan Chin and Curtis Lew required by Section
G.2(a) of the A&M Agreement.  Krentzman and Burtscher each agree to pay $1.10
per share for these parity shares, payable without interest at the earlier of
(i) the date of significant funding (as stated in paragraph 1 above) or (ii) the
date upon which they individually receive a raise in salary under their
employment agreement.

          3.  Except for those shares being paid for as set forth in section 2
above, all shares issued pursuant to the A&M Agreement, including as amended by
this Amendment, are part of the exchange unrelated to any compensation due
Krentzman and Burtscher under their employment agreements.

     The next order of business was review of a proposed agency agreement
submitted to the Corporation by Mr. Chin and Mr. Lew. Mr. Brownfield reported
for the Compensation Committee that the Committee had reviewed the proposal,
which features future compensation to the agents based on the lesser of 3% of
gross receipts of 25% net margin realized on revenues from the proposed China
venture. In addition, the Corporation would provide, as an additional incentive,
5% of the ownership interest in the China venture entity that will come to the
Corporation, but only when the venture entity achieves a liquidation event. Mr.
Brownfield confirmed that the Committee determined that these were fair terms
reflective of market conditions. Mr Chin indicated his (and Mr. Lew's)
willingness to proceed on the basis of these terms. After further discussion,
upon motion to be made and seconded (Wong/Brownfield), and with directors Chin
and Lew abstaining, it was, by unanimous vote


                                       3

     RESOLVED that the terms of the proposed agency agreement with Messrs. Chin
     and Lew approved by the Compensation Committee are hereby adopted and
     approved by the Board of Directors, and the Chairman and the President of
     the Corporation are each authorized to execute and deliver an agency
     agreement incorporating those terms on behalf of the Corporation.
