information, including "Risk Factors" and the Consolidated Financial Statements
and notes thereto appearing elsewhere in this Prospectus. Unless otherwise
indicated, references in this Prospectus to "Teltrust" or the "Company" refer

                                  THE COMPANY
 
  Teltrust is a leading independent outsource provider of a broad range of
enhanced call processing and calling card services to the domestic
telecommunications industry. The Company believes that it offers the most
comprehensive suite of services of any independent outsource provider in its
industry. This diversified suite of services includes call completion, national
directory assistance and third-party verification services in addition to
calling card services. Teltrust serves its customers through state-of-the-art
technology and switch-based call processing platforms and, as of March 1998,
more than 1,000 employees. The Company's customers include regional Bell
operating company ("RBOC") affiliates (such as BellSouth Long Distance and
BellSouth Public Communications), pay telephone and hospitality aggregators
(such as Peoples Telephone Company, AMI Telecommunications and Global Net),
interexchange carriers ("IXCs") (such as US Long Distance, WorldCom and LCI
International), and other large telecommunications resellers or users (such as
TON Services and Eastern Communications Network). The Company has also recently
established contractual relationships with affiliates of Ameritech Corporation
(Ameritech Communications and Ameritech Services) and emerging
telecommunications companies including competitive local exchange carriers
("CLECs") (such as Nextlink and Cox Com), wireless providers (such as
Centennial Cellular, Omnipoint Communications and PowerTel) and international
carriers (such as Justice Technology Corp. and Star Telecommunications). Many
of the Company's customers purchase a number of the Company's services under
multi-year contracts and utilize Teltrust to provide complex outsourcing
solutions. During the quarter ended March 31, 1998, Teltrust processed over 21
million call processing transactions and decremented more than 17.6 million
domestic minutes for its prepaid calling card customers.
 
  A brief description of Teltrust's enhanced call processing and calling card
service offerings is as follows:
 
CALL PROCESSING SERVICES
 
  CALL COMPLETION SERVICES. Teltrust provides call completion services to
RBOCs, IXCs, other local exchange carriers ("LECs"), CLECs, wireless providers,
pay telephone providers, hospitality service providers and international
carriers. Call completion services include calling card calling, collect
calling and third-party billed calling. A majority of calls handled are branded
in the names of Teltrust's customers. The Company also offers STATUS(TM), a
proprietary refund and repair service.
 
  NATIONAL DIRECTORY ASSISTANCE SERVICES. Teltrust provides national directory
assistance services to RBOCs, IXCs, LECs, wireless providers and other
telecommunications resellers. As part of its national directory assistance
services, the Company offers enhanced features such as direct call connection,
reverse searches and standard industrial classification code searches.
 
  THIRD-PARTY VERIFICATION SERVICES. Teltrust provides third-party verification
services to RBOCs, IXCs, LECs, CLECs, international carriers and
telecommunications resellers. These services allow Teltrust customers to verify
consumer orders for changes in local and long distance telephone service and
public utility service in compliance with regulations promulgated by the
Federal Communications Commission ("FCC") and many state public utility
commissions ("PUCs"). These regulations were implemented to combat "slamming"
(the practice of changing a consumer's telecommunications or other utility
provider without such consumer's knowledge).
 
CALLING CARD SERVICES
 
  The Company provides calling card programs and platform services to RBOCs,
IXCs, LECs, CLECs, wireless providers, major retail operations and other firms
to allow such customers to sell prepaid and postpaid
 
                                       3
<PAGE>
 
calling card products to the general public. Teltrust's customers utilize the
Company's advanced point-of-sale activation technology and can offer users of
calling cards serviced by Teltrust access to numerous enhanced services,
including voice mail, paging, faxing and conference calling.
 
INDUSTRY
 
  During the 1990s, changes in the regulatory environment and the emergence of
new technologies have created a growing and fiercely competitive environment in
the telecommunications industry. According to FCC reports, the
telecommunications market in the United States, including local, long distance,
wireless and prepaid calling, generated revenues of more than $220 billion in
1996. As new participants enter the market, telecommunications companies,
including RBOCs, IXCs, LECs, CLECs and wireless providers, are evaluating their
existing services and seeking opportunities that will allow them to compete
more effectively, reduce operating costs, and increase usage, market
penetration and customer retention. Many of these companies are seeking access
to call completion services, national directory assistance services and calling
card platforms which are considered essential by end-users. Partnering with an
outsource provider, such as Teltrust, allows telecommunications companies to
bring to market new value-added products and services in a more expeditious and
cost-effective manner than by building the necessary infrastructure to provide
such services internally and enables telecommunications companies to focus on
their core competencies and strategies.
 
GROWTH STRATEGY
 
  Teltrust believes it is well-positioned to capitalize on the changes in the
telecommunications industry by utilizing its competitive advantages as an
experienced independent outsource provider of a broad range of enhanced call
processing and calling card services. Teltrust's distinct operational advantage
is its focus on providing enhanced call processing and calling card services on
a wholesale basis to its customers. This emphasis has allowed the Company to
avoid competing in the core businesses of its customers and enables Teltrust to
concentrate on offering and expanding a diversified suite of enhanced call
processing and calling card services. Other advantages include the Company's
use of a proven operating infrastructure and technology that can be customized
to respond to customer needs, a commitment to excellence in customer service
and a demonstrated ability to meet the performance expectations of
sophisticated customers with demanding and changing standards.
 
  Teltrust's goal is to be the premier provider of outsourced enhanced call
processing and calling card services. The key elements of the Company's focused
growth strategy are (i) cross-selling its current service offerings to existing
customers, (ii) pursuing customers in new and existing markets, (iii)
developing new services, (iv) leveraging its operating structure to enable the
Company to expand its business and meet the needs and requirements of current
and future customers, (v) maintaining its dedication to high levels of customer
satisfaction and (vi) considering strategic acquisitions.
 
QUEST ACQUISITION
 
  On December 31, 1997, the Company completed the acquisition of Quest
International Group, Inc. and its affiliated companies ("Quest"), a pioneer in
the United States prepaid calling industry. This acquisition enabled the
Company to combine its existing calling card operations with Quest's
proprietary technology, innovative management and marketing team. Teltrust
believes this acquisition will enable it to offer its customers a broader range
of services and position it for additional growth in its calling card services
business.
 
  Teltrust was incorporated under the laws of Delaware in 1998, and its
predecessor was incorporated under the laws of Utah in 1986. The Company's
principal executive offices are located at 6322 South 3000 East, Salt Lake
City, Utah, 84121, and its telephone number is (801) 535-2000.
 
  "Teltrust", "Quest" and the Company's logo are trademarks of the Company and
are used throughout this document as such. All other trademarks and trade names
referred to in this Prospectus are the property of their respective owners.

                                 RISK FACTORS
 
  An investment in the Common Stock offered hereby involves a high degree of
risk. Prospective investors should carefully consider the following risk
factors, in addition to the other information contained in this Prospectus,
before purchasing the Common Stock offered hereby. This Prospectus contains
forward-looking statements within the meaning of the federal securities laws.
Discussions containing such forward-looking statements may be found in the
material set forth below and under "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business," as well as
elsewhere in this Prospectus. Prospective investors are cautioned that any
such forward-looking statements are not guarantees of future performance and
involve risks and uncertainties. Actual events or results may differ
materially from those discussed in the forward-looking statements as a result
of various factors, including, without limitation, the risk factors set forth
below and other matters set forth in this Prospectus.
 
HISTORY OF OPERATING LOSSES
 
  Primarily as a result of expenses associated with the expansion of its
business and certain infrastructure and capital equipment upgrades undertaken
since 1993, the Company has incurred significant net operating losses and
negative cash flows from operating activities. As of December 31, 1997, the
Company had an accumulated deficit of $23.6 million. For the years ended
December 31, 1995, 1996 and 1997, net losses were approximately $2.1 million,
$2.5 million and $13.2 million, respectively, and the Company generated
negative cash flows from operating activities of approximately $5.3 million,
$3.5 million and $6.7 million, respectively. The Company expects to incur
significant expenditures in the future in connection with the development and
expansion of its call centers, network, services and customer base. Although
the Company achieved profitability and positive cash flows in the quarter
ended March 31, 1998, there can be no assurance that the Company will achieve
or sustain profitability or generate positive cash flows from operating
activities in the future. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
FUTURE NEEDS FOR ADDITIONAL FINANCING
 
  The Company's continued development, expansion and delivery of existing
services and its further development and enhancement of new services will
require substantial capital expenditures. The funding of these expenditures
will depend in part upon the Company's ability to raise substantial additional
financing. Since January 1, 1996, the Company has raised approximately $15.0
million from preferred equity financings, obtained $2.0 million in debt
financing and established a $20.0 million senior secured credit facility (the
"Credit Facility") of which $12.1 million had been drawn at December 31, 1997.
In addition, the Company continues to consider potential acquisitions or other
arrangements that may fit the Company's strategic plan. Any such acquisitions
or arrangements that the Company might consider are likely to require
additional equity or debt financing.
 
  The Company believes that its existing cash and cash equivalents,
availability under the Credit Facility and expected cash from operations will
be sufficient to fund its operating activities through at least the end of
1998.
 
  To meet its capital requirements and to successfully implement its growth
strategy thereafter, the Company anticipates that it will be required to sell
additional equity securities, increase the Credit Facility, obtain additional
credit facilities or sell additional debt securities. The Company may not be
able to obtain additional required capital on satisfactory terms, if at all.
Any failure by the Company in its efforts to raise the funds necessary to
finance future cash requirements could have a material adverse effect on the
Company's business, financial condition and results of operations. If Teltrust
raises additional funds through the issuance of equity securities, dilution to
the Company's existing stockholders may result. If the Company raises
additional funds through the incurrence of debt, the agreements governing such
debt may contain restrictive financial, operating and security covenants.
Because the Credit Facility is secured by substantially all of its assets, the
Company may not be able to obtain future financings which require security.
Because there can be no assurance that the Company will be able to obtain
additional financing, the Company may be unable to fund its ongoing
operations,
 
                                       8
<PAGE>
 
which would have a material adverse effect on its business, financial
condition and results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Liquidity and Capital
Resources."
 
RISKS RELATED TO SUBSTANTIAL CUSTOMER CONTRACT
 
  The Company has entered into three contracts with affiliates of BellSouth
Corporation ("BellSouth"), BellSouth Long Distance ("BSLD") and BellSouth
Public Communications ("BSPC"), under which Teltrust has agreed to provide a
variety of services. Under the terms of the Company's October 1997 agreement
with BSLD, Teltrust provides enhanced call processing services for calls
placed through the 1-800-BELLSOUTH(TM) access number and certain network
services. In providing such services, the Company recognizes operating
revenues directly from end-users and pays BSLD certain commissions for
interLATA service outside the nine-state BellSouth region. The Company also
contributes to the expenses of marketing the 1-800-BELLSOUTH(TM) name.
BellSouth is currently prohibited from providing interLATA service within the
nine-state BellSouth region although it has applied for regulatory approval to
provide such services. When BellSouth obtains such approval, the Company will
no longer earn its operating revenues directly from end-users as provided in
the October 1997 contract with BSLD. Instead, the arrangement for this service
will change substantially so that the Company will earn operating revenues
directly from BSLD only for the specific services the Company provides to BSLD
under its November 1996 contract with BSLD. In addition, when BellSouth
obtains the aforementioned approval, it is expected that BSLD will cease using
the Company for automated call processing services. As a result of these
factors, the Company expects that there will be a substantial reduction in
operating revenues to the Company and it is unlikely that operating revenues
under these contracts will return to the level of operating revenues prior to
such change. Although the Company believes that, after such changes in its
contracts with BellSouth, the services it will provide to BellSouth will
generate significant gross profit, the operating revenues and gross profits
generated from such services are dependent upon the timing of BellSouth's
achieving a meaningful long distance market penetration, if at all, in the
markets that BellSouth will serve. Accordingly, it is unlikely that after such
changes the Company's gross profit under these contracts will return to the
levels achieved prior to such changes. For the year ended December 31, 1997
and the quarter ended March 31, 1998, operating revenues from the October 1997
contract accounted for approximately 2.7% and 27.5%, respectively, of the
Company's total operating revenues. Failure to return to such levels of gross
profit from such contracts may have a material adverse effect on its business,
financial condition and results of operations. In addition, future contracts
with RBOC affiliates may also contain provisions that could result in a
similar transition upon the customer's obtaining regulatory approval to
provide interLATA long distance service. See "Business--Significant Customer
Contracts."
 
SIGNIFICANT CUSTOMER RELATIONSHIPS
 
  For the year ended December 31, 1997, revenues from the three contracts
between the Company and BSLD and BSPC accounted for approximately 2.7%, 11.9%
and 1.6% of the Company's total operating revenues. For the quarter ended
March 31, 1998, these three contracts accounted for approximately 27.5%, 7.4%
and 3.1% of the Company's total operating revenues. In addition, the Company
currently has contracts with two subsidiaries of Ameritech Corporation,
Ameritech Services ("ASI") and Ameritech Communications ("ACI"). The Company
began earning revenues under the Ameritech contracts during April 1998. The
aforementioned contracts require payment of a contractually-agreed upon amount
in the event of early termination of such contracts without cause. There can
be no assurance, however, that the Company would be able to collect such
amounts or that such amounts, if received, together with operating revenues
generated under such contracts, would sufficiently compensate the Company for
the investment it has made to support the canceled contracts. The amount of
such termination fees are relatively insignificant when compared to the
operating revenues generated and expected to be generated under such
contracts. There can be no assurance, however, that such expected revenues
will be realized.
 
  None of the Company's contracts with BSLD, ASI or ACI have current terms
that extend beyond the year 2000. The Company's contract with BSPC currently
terminates in 2002. There can be no assurance that any of these customers will
renew their contracts after the expiration of their current terms, nor can
there be any assurance that these customers will not terminate the contracts
during their initial terms. In addition, if the contracts are not
 
                                       9
<PAGE>
 
renewed, there can be no assurance that the Company can replace these
contracts with contracts with other customers. Consequently, the failure of
the Company to obtain renewal of any of the contracts with BSLD, BSPC, ASI or
ACI, or the termination of such contracts, could have a material adverse
effect on the Company's business, financial condition and results of
operations. See "Business--Significant Customer Contracts."
 
  The Company's five largest customers accounted for 20.4%, 27.3% and 39.7% of
the Company's operating revenues for 1995, 1996 and 1997, respectively. The
Company expects that operating revenues attributable to a relatively small
number of customers including BSPC, BSLD, ASI and ACI, will represent a
significant percentage of its total operating revenues for the foreseeable
future. The terms of the Company's contracts with these customers vary from
one to three years. Although Teltrust believes that it has good relationships
with its customers, there can be no assurance that the Company's largest
customers will continue to use the Company's services in amounts similar to
previous years or at all. The loss or significant reduction of business from
any of the Company's large customers could have a material adverse effect on
the Company's business, financial condition and results of operations.
Additionally, customers who account for significant portions of the Company's
operating revenues may have the ability to negotiate prices for the Company's
services that are more favorable to the customer and that result in lower
profit margins for the Company. See "Business--Significant Customer
Contracts."
 
DEPENDENCE ON THE RAPIDLY CHANGING TELECOMMUNICATIONS INDUSTRY
 
  Substantially all of the Company's revenues to date have resulted from
services provided to companies in the telecommunications industry.
Developments in the telecommunications industry generally or by any reduction
in expenditures for, or future outsourcing of, activities by
telecommunications companies could materially and adversely affect the
Company's business, financial condition and results of operations.
Expenditures by telecommunications companies could be negatively impacted by,
among other things, changes in governmental regulations designed to alter the
manner in which companies provide their products.
 
  Recent events, including the passage of the Telecommunications Act of 1996,
are expected to result in an increasing number of telecommunications companies
operating in each market. This may result in competitive situations that
unfavorably impact the Company, such as the withdrawal of a customer from a
market that the Company serves or the acquisition or merger of a major
customer, where the acquiror or surviving entity provides those services
itself or obtains them from another third-party or exerts substantial
influence on the contract negotiation process. In addition, the creation of
alliances and joint ventures among telecommunications companies may increase
the negotiating leverage for these carriers as they deal with providers of
services such as those the Company offers. Although the Company believes that
an increase in the number of providers generally will be beneficial to the
Company as the providers look for ways to differentiate their services, no
assurance can be given that the Company will not be adversely impacted, either
directly or indirectly, by the potential changes in the marketplace. See
"Business--Significant Customer Contracts."
 
DEPENDENCE ON CERTAIN SUPPLIERS
 
  The Company relies on other telecommunications companies to supply certain
key components of its network infrastructure, including telecommunications
services, network capacity and switching and networking equipment, which, in
the quantities and quality demanded by the Company, are available only from
certain limited sources. The Company is also dependent upon certain IXCs and
other carriers to provide telecommunications services and facilities to the
Company and its customers. The Company relies on a national data provider to
supply information used by the Company in providing its national directory
assistance services and on a third-party billing and collection service to
perform certain billing and collection services for the Company's operations.
The Company has, from time to time, experienced delays, outages or other
problems in receiving telecommunications components, services and facilities
and data which it requests from certain suppliers, and there can be no
assurance that the Company will be able to obtain such services or facilities
or data on the scale and within the time frames required by the Company at an
affordable cost, or at all. Any failure to obtain such components, services,
facilities or data on a timely basis, at an affordable cost or at all, would
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Business--Operations and Technology."
 
                                      10
<PAGE>
 
DEPENDENCE UPON NETWORK INFRASTRUCTURE; RISK OF SYSTEM FAILURE; SECURITY RISKS
 
  The Company's success in marketing its services to telecommunications
companies requires that the Company provide superior reliability, capacity and
security via its network infrastructure. The Company owns and operates
switching, call processing and networking sites located in Salt Lake City and
additional facilities in Atlanta, Los Angeles, Miami and New York City. The
Company's call processing platforms and networks and the third-party networks
upon which they depend are subject to physical damage, power loss, capacity
limitations, software defects, breaches of security (by computer virus, break-
ins or otherwise) and other factors, certain of which may cause interruptions
in service or reduced capacity for customers. Although the Company has taken
precautions to protect itself and its customers from events that could
interrupt delivery of services, including the use of back-up systems and
redundant operations, there can be no assurance that a fire, act of sabotage,
technical failure, human error, natural disaster or any similar event would
not cause the failure of a significant technical component, thereby resulting
in a failure of service. Interruptions in service, capacity limitations or
security breaches could have a material adverse effect on the Company's
business, financial condition and results of operations. Certain losses
suffered by Teltrust as a result of any infrastructure-related disruptions
would be covered by business interruption insurance maintained by the Company.
However, there can be no assurance that the Company will be able to maintain
its business interruption insurance, that such insurance will continue to be
available at reasonable prices, that such insurance would cover all such
losses or that such insurance would be sufficient to compensate the Company
for losses it may experience due to the Company's inability to provide
services to its customers. See "Business--Operations and Technology."
 
RISKS RELATED TO RAPID GROWTH
 
  Although the Company has recently experienced substantial growth in
operating revenues, there can be no assurance that such growth will continue
or that the Company will be able to effectively manage such growth. The
Company's ability to continue to grow and to effectively manage such growth
may be affected by various factors, many of which are not within the Company's
control, including competition and federal and state regulation of the
telecommunications industry. The Company's rapid growth has placed, and is
expected to continue to place, significant demands on all aspects of the
Company's business, including its administrative, technical and financial
personnel and systems. The Company's operating and reporting systems will
require enhancement and substantial investment in the future to accommodate
the Company's anticipated growth. There can be no assurance that the Company
will not encounter difficulties in expanding these systems to meet its future
needs. If the Company is unable to respond to and manage changing business
conditions, the quality of its services and its results of operations could be
materially adversely affected. Difficulties in managing continued growth could
have a material adverse effect on the 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 MANAGEMENT AND PERSONNEL; ABILITY TO HIRE ADDITIONAL
QUALIFIED PERSONNEL
 
  The Company's future operating results will substantially depend on the
ability of its officers and key employees to manage its growth, to attract,
retain and integrate additional highly qualified management, technical and
financial personnel and to implement and/or improve its technical,
administrative, financial controls and reporting systems. Further, the loss of
key management personnel would likely have a material adverse impact on the
Company. Although the Company believes that it would be able to locate
suitable replacements for such management personnel if their services were
lost, there can be no assurance that qualified personnel will be available in
the regions in which the Company operates. Accordingly, the loss of the
services of any of such management personnel could have a material adverse
effect on the Company. Failure to retain and attract additional management
personnel who can manage the Company's growth effectively would have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
  The success of the Company also depends upon its ability to hire and retain
qualified operating, marketing, sales, financial, accounting and technical
personnel. Competition for qualified personnel in the telecommunications
industry is intense and, accordingly, there can be no assurance that the
Company will be
 
                                      11
<PAGE>
 
able to continue to hire or retain necessary personnel. Further, tight labor
markets in areas where the Company operates, including the existence of
significant competition for skilled employees in the Salt Lake City area, may
affect the Company's ability to recruit and hire the substantial number of new
accounting, sales, information systems, network engineering and support
personnel and service agents required to implement the Company's growth
strategy. See "Management."
 
COMPETITION
 
  Telecommunications markets are intensely competitive, rapidly evolving and
subject to constant technological change. The Company currently faces
significant competition in each of the markets in which it operates and
expects competition to increase in the future. Many of the Company's current
and potential competitors are substantially larger and have greater financial,
technical, engineering, personnel and marketing resources; longer operating
histories; greater name recognition; and larger and more diversified customer
bases than the Company. Telecommunications companies compete for customers
(both in the wholesale and end-user segments) on the basis of service,
quality, price, reputation, technological innovation and experience. The
Company believes that existing competitors are likely to continue to expand
their service offerings to their customers. Moreover, with the continuing
trend toward business alliances in the telecommunications industry and the
absence of substantial barriers to entry in the call completion, national
directory assistance, third-party verification and calling card services
markets, the Company expects that new competitors are likely to enter the
telecommunications market and attempt to market telecommunications services
similar to the Company's services, which would result in greater competition.
 
  The ability of the Company to compete effectively in telecommunications
markets will depend upon the Company's continued ability to provide high
quality services at prices generally competitive with, or lower than, those
charged by its competitors. Certain of the Company's current and potential
competitors dominate the telecommunications industry and have the financial
resources to enable them to withstand substantial price competition, which is
expected to increase significantly, and there can be no assurance that the
Company will be able to compete successfully in the future. Moreover, there
can be no assurance that certain of the Company's competitors will not be
better positioned to negotiate contracts with telecommunications companies
that are more favorable than contracts negotiated by the Company. In addition,
there can be no assurance that competition from existing or new competitors or
a decrease in the rates charged for telecommunications services by competitors
would not have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business--Competition."
 
IMPACT OF TECHNOLOGICAL CHANGE; DEPENDENCE ON NEW SERVICES
 
  The market for the Company's services is characterized by rapidly changing
technology, evolving industry standards, emerging competition and frequent new
product and service introductions. The Company's future success will depend on
the continued use of its existing services and products, the acceptance of new
services and products in the markets in which Teltrust operates and the
Company's ability to develop new products and services or adapt existing
products and services to keep pace with changes in the telecommunications
industry. Future technological changes, including changes related to
automation of certain call processing functions, network protocols and
software, could have a material adverse effect on the Company's business,
results of operations and financial condition. There can be no assurance that
the Company will successfully identify new service opportunities and develop
and bring new services to market in a timely manner. The Company's pursuit of
necessary technological advances may require substantial time and expense, and
there can be no assurance that the Company will be successful in adapting to
new technologies and market and product evolutions. In addition, there can be
no assurance that the Company will not experience difficulties that could
delay or prevent the successful development, introduction and marketing of its
existing services or that its new services or enhancements thereto will
adequately meet the requirements of the marketplace and achieve market
acceptance. Delay in the introduction of new services or enhancements, or the
failure of such services or enhancements to achieve market acceptance could
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Business--Industry Overview."

YEAR 2000 COMPLIANCE
 
  The Company has reviewed its information and technology systems to assess
what changes might be needed for those systems to recognize the year 2000
("Y2K") and not to treat any date after December 31, 1999 as a date during the
twentieth century. Management believes that all such changes have been or will
be implemented in an orderly and timely manner and without material cost. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Year 2000 Compliance." The Company has begun to coordinate its
response to these issues with those third parties with whom the Company
engages in electronic transactions, both domestically and internationally,
including suppliers, customers, creditors and financial service organizations,
although the Company cannot effectively ensure against all potential Y2K
problems that might originate with third parties. If the Company or any third
party with whom the Company does business were to have a Y2K problem, the
Company's business could be seriously disrupted and the Company's business,
financial condition and results of operations could be materially adversely
affected. See "Business--Operations and Technology--Year 2000 Compliance."
 
DEPENDENCE ON PROPRIETARY AND LICENSED SOFTWARE
 
  The Company has developed, and depends on, its own proprietary in-house data
reporting and tracking system to provide a series of database query and report
capabilities that are used to track inventory, control fraud and monitor
system usage. The Company also depends on its software, as well as software
developed by third parties, to provide services to its customers. The software
utilized by the Company in providing its services may contain undetected
errors. Although the Company engages in extensive testing of its software
prior to using the software on its network, there can be no assurance that
errors will not be found in software after commencement of use of such
software. Any such error may result in partial or total failure of the
Company's network, requiring the Company to commit additional and
unanticipated funds for further product development, including the retention
of additional programming personnel. In addition, any such failure may result
in a loss of customers and a corresponding decrease in revenue which could
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Business--Operations and Technology."
 
  The Company regards certain of the software it uses as proprietary and
relies primarily on a combination of statutory and common law copyright,
trademark and trade secret laws, customer licensing agreements, employee and
third-party nondisclosure agreements and other methods to protect its
proprietary rights. These laws and contractual provisions provide only limited
protection of the Company's proprietary rights. Despite the Company's efforts
to protect its proprietary rights, it may be possible for a third party to
copy or otherwise obtain and use the Company's technology without
authorization or to develop similar technology independently. If unauthorized
copying or misuse of the Company's products were to occur to any substantial
degree, the Company's business, results of operations and financial condition
could be materially adversely affected. There can be no assurance that the
Company's means of protecting its proprietary rights will be adequate or that
the Company's competitors will not independently develop similar technology.
 
  Although the Company does not believe that it is infringing intellectual
property rights of third parties in its operations, there can be no assurance
that third parties will not claim that the Company's current or future
products violate the proprietary rights of others. The Company expects that
software developers will increasingly be subject to such claims as the number
of products and competitors providing products and services to the
telecommunications industry grows. Any such claim, with or without merit,
could result in costly litigation, require significant management resources,
require the Company to enter into royalty or licensing agreements or cause the
Company to discontinue the use of the challenged trade name, service mark or
technology, any of which could have a material adverse effect on the Company's
business, financial condition and results of operations. Furthermore, such
royalty or licensing agreements, if required, may not be available on terms
acceptable to the Company or at all. See "Business--Operations and
Technology."
 
RISKS OF OPERATING IN A REGULATED INDUSTRY
 
  As a common carrier, the Company is subject to substantial federal, state,
and local regulation. The following paragraphs describe certain impacts of
these regulations as currently in force; however, regulatory
 
                                      13
<PAGE>
 
policies are subject to change as a result of agency, legislative and judicial
actions and there can be no assurance that the Company will not be adversely
affected by future changes of this nature.
 
  Teltrust currently must file with the FCC tariffs setting forth the
Company's rates, terms and conditions of service for prepaid and postpaid
calling card operations and call processing services and must provide certain
information about its interstate and international long distance traffic. In
addition, the Company is required to maintain a certificate, issued by the
FCC, in connection with its international services. State regulatory agencies
regulate intrastate communications, call completion services, third-party
verification services, in-state long distance services and prepaid, postpaid
and proprietary calling card services. The Company generally must obtain and
maintain certificates of public convenience and necessity from regulatory
authorities in most states in which it offers services. In most of these
jurisdictions, the Company must file and obtain prior regulatory approval of
tariffs for intrastate services. In addition, the Company must update or amend
the tariffs and, in some cases, the certificates of public convenience and
necessity when rates are adjusted or new products are added to the
telecommunications services offered by the Company. The FCC and numerous state
agencies also impose prior approval requirements on transfers of control,
including corporate reorganizations, and assignments of certain regulatory
authorizations. Failure by the Company to adhere to these filing requirements
and other regulations could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
  The Telecommunications Act of 1996 directs the FCC to prescribe mechanisms
for the preservation of universal service, the promotion of nationwide access
to telecommunications services in rural, insular and high cost areas that are
reasonably comparable in price and type to those found in urban areas and the
promotion of access to advanced services for schools, libraries and certain
health care providers. Providers of interstate telecommunications, including
call completion services providers, pay telephone providers and private
network operators that offer services to others for a fee on a non-common
carrier basis, must contribute toward the funding of universal service
according to a formula prescribed by the FCC. Although the Company's
competitors will be similarly affected, the universal service fund annual
assessment may have a material adverse effect on the long-term financial
condition of the Company.
 
  Section 276 of the 1996 Telecommunications Act mandated the establishment of
a per call compensation plan to insure that all pay telephone providers are
fairly compensated for each completed intrastate and interstate pay telephone
initiated coinless call. Such calls include those placed to toll free numbers
(800/888), dial around access code calls (such as 1-800-BELLSOUTH(TM)) and
other such access code calls. The FCC has established a two-year "default"
compensation rate, payable by all IXCs including the Company, of $0.284 per
compensable call. At the end of the two year interim period, the per call pay
telephone compensation rate will be the deregulated market-based local coin
rate less $0.066. The current FCC rules became effective on October 7, 1997,
but continue to be subject to regulatory and legal challenges. The Company is
unable to predict whether this regulation or other potential changes in the
communications laws, other regulations or determinations will have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
  In May 1997, the FCC adopted changes to its system of interstate access
charges to make them compatible with the pro-competitive, deregulatory
framework established by the Telecommunications Act of 1996. The FCC's access
reform order adopts various reforms to the existing rate structure for
interstate access that are designed to move access charges, over time, to more
economically efficient levels and rate structures. The FCC's access reform
order also imposes the phase-in of replacing usage-based carrier common line
charges with a line-based flat fee to be assessed upon all telecommunications
carriers beginning on January 1, 1998. In addition, the FCC's access order
requires LECs to reduce their access revenue requirements by reducing
interconnection access charges to telecommunications carriers. Although the
Company's competitors will be similarly affected, the changes in the system of
interstate access charges may have a material adverse effect on the business,
financial condition and results of operations of the Company.
 
  In January 1998, the FCC addressed what it viewed as widespread consumer
dissatisfaction concerning high charges by many IXCs and call completion
service providers for calls from public phones and other aggregator locations
such as pay telephones, hospitals, hospitality locations and educational
institutions. Although it declined to implement a concept known as "billed
party preference," which would have required that the billed
 
                                      14
<PAGE>
 
party be allowed to choose the preferred long-distance service provider for
each of its calls, the FCC issued an order requiring call processing service
providers and IXCs to disclose orally to "away from home callers" how to
obtain the total cost of a 0+ interstate domestic call before the call is
connected. The Company is unable to predict whether this regulation or other
potential changes in the communications laws, other regulations or
determinations could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business--Government
Regulation."
 
RISKS RELATED TO STRATEGIC INVESTMENTS OR BUSINESS COMBINATIONS
 
  The Company recently completed the acquisition of Quest and may consider
future acquisitions of, or strategic investments in, companies engaged in
businesses similar or related to the business of the Company in order to
complement Teltrust's existing services, broaden its customer base and improve
its operating efficiencies. Acquisitions and strategic investments also
involve numerous additional risks, including difficulties in the integration
of the operations, services, products and personnel of the acquired company,
which could result in charges to earnings or otherwise adversely effect the
Company's operating results. In addition, there can be no assurance that
acquisition opportunities will be available, that the Company will have access
to the capital required to finance potential acquisitions, that the Company
will acquire businesses, that any acquired business will be profitable or that
any acquisition or strategic investment effected through the issuance of
equity will not ultimately prove to be dilutive. There can be no assurance
that the anticipated benefits of the Quest acquisition will be fully realized
or that the combination of the Company and Quest will ultimately be considered
successful.
 
  In addition, the Company from time to time engages in discussions with
potential business partners to consider formation of business combinations or
strategic alliances that would expand the reach of the Company's networks or
services and potential strategic investors who have expressed an interest in
making an investment in the Company. Such acquisitions, combinations or
alliances, if consummated, could divert the resources and management time of
the Company and may require integration with the Company's existing networks
and services. There can be no assurance that any acquisitions, combinations or
alliances will occur or, if consummated, would be on terms favorable to the
Company or would be successfully integrated into the Company's operations.
 
CONTROL BY CERTAIN STOCKHOLDERS AND MANAGEMENT
 
  Upon completion of the Offering, the Company's Directors and executive
officers are expected to own beneficially approximately 64.7% of the
outstanding Common Stock. At such time, approximately 22.6% of the outstanding
Common Stock will be beneficially owned by Lyle O. Keys, the Company's
Chairman and 11.8% of the outstanding Common Stock will be beneficially owned
by Carmelo Catalano, a Director of the Company. In addition, at such time,
entities affiliated with Media/Communications Partners, whose designees occupy
two positions on the Board of Directors, will own approximately 23.6% of the
outstanding Common Stock. As a result, these stockholders will be able to
exercise significant influence over all matters requiring stockholder
approval, including the election of directors and the approval of significant
corporate transactions. Such concentration of ownership may also have the
effect of delaying or preventing a change in control of the Company. See
"Principal and Selling Stockholders."
 
SEASONALITY; FACTORS AFFECTING OPERATING RESULTS; POTENTIAL FLUCTUATIONS IN
PERIOD-TO-PERIOD RESULTS
 
  The Company's sales have been, and the Company expects that its sales will
continue to be, somewhat seasonal, due to the nature of call traffic from
independent and LEC-owned pay telephones and the use of prepaid and other
calling cards. Traditional agent-assisted long distance services produce peak
revenues during the summer months, coincident with domestic travel and
vacation patterns. To a lesser degree, national directory assistance, prepaid
and other calling card and third-party verification services are also affected
by seasonal demand fluctuations with demand peaking in the spring and summer
months.
 
  The Company's operating results have varied significantly from period-to-
period in the past and may vary significantly in the future. Factors that may
cause the Company's operating results to vary include: (i) changes in
 
                                      15
<PAGE>
 
operating expenses; (ii) the timing of the introduction of services; (iii)
market acceptance of new and enhanced versions of services; (iv) potential
acquisitions; (v) changes in legislation and regulations that affect the
competitive environment for services; (vi) customer marketing strategies; and
(vii) general economic factors. As a result of these factors, the Company
believes that period-to-period comparisons of its results of operations are
not necessarily meaningful and should not be relied upon as an indication of
future performance.
 
RISK OF LOSS FROM RETURNED TRANSACTIONS; FRAUD; BAD DEBT; THEFT OF SERVICES
 
  The Company utilizes national and credit card clearance systems for
electronic credit card settlement and billing of telephone calls. The Company
often bears the same credit risks normally assumed by other users of these
systems arising from returned transactions that are caused by closed accounts,
frozen accounts, unauthorized use, disputes, theft or fraud. The Company's
relationship with providers of merchant card services, including credit card
issuers, could be adversely affected by excessive uncollectables or
chargebacks, which are generally higher in the telecommunications services
industry than in other industries, particularly with respect to recharging (or
"refreshing") the limits on prepaid calling cards because the transaction does
not require a cardholder signature. Termination of the Company's ability to
refresh prepaid calling cards through merchant card services would have a
material adverse effect on the business, financial condition and results of
operations of the Company. Although the Company attempts to limit its
financial exposure by limiting the amount that consumers can refresh within
specified time frames, from time to time, persons have obtained services
without rendering payment to the Company by unlawfully utilizing the Company's
access numbers and personal identification numbers. The Company attempts to
manage these credit, theft and fraud risks through its internal controls,
monitoring and blocking systems. The Company also maintains reserves which it
deems adequate for such risks. Past experience in estimating and establishing
reserves and the Company's historical losses are not necessarily accurate
indications of the future. Although the Company believes that its risk
management and bad debt reserve practices are adequate, there can be no
assurance that the Company's risk management practices or reserves will be
sufficient to protect the Company from unauthorized or returned transactions
or thefts of services which could have a material adverse effect on the
Company. See "Business--Operations and Technology--Fraud Prevention."
 
POSSIBLE DELAY IN RECOGNIZING A PORTION OF DEFERRED REVENUE
 
  The sale of long distance domestic and outbound international telephone
service through prepaid calling cards may be subject to "escheat" laws in
various states. These laws generally provide that payments or deposits
received in advance or in anticipation of the provision of utility (including
telephone) services that remain unclaimed for a specific period of time after
the termination of such services are deemed "abandoned property" and must be
submitted to the state. The Company, however, is not aware of any case in
which escheat laws have been applied to unused balances remaining on prepaid
calling cards and does not believe that such laws are applicable. In the event
that such laws were deemed applicable and tariffed service charges for periods
of non-use had not accumulated to reduce such unused balance, the Company may
be unable to recognize the portion of its deferred revenue remaining upon the
expiration of the cards with unused calling time. In such event, the Company
may be required to deliver such amounts to certain states in accordance with
these laws, which could have a material adverse effect on the Company.
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
  The sale of a substantial number of shares of Common Stock of the Company in
the public market could adversely affect the market price of the Common Stock.
After giving effect to the offering of the Company's 2,500,000 shares of
Common Stock, the 3,200,000 shares offered hereby will be eligible for
immediate sale in the public market without restriction under the Securities
Act (except that any shares purchased in the Offering by "affiliates" of the
Company may generally be resold only in compliance with applicable provisions
of Rule 144). Beginning 90 days after the date of this Prospectus, an
additional    shares may be resold under Rule 144 subject to the volume and
manner limitations set forth in Rule 144 and an additional     shares may be
resold under Rule 144 without such restrictions (in each case, subject to the
lock-up agreements described in "Underwriting"). Holders of approximately
of these shares have contractual rights to have those shares
 
                                      16
<PAGE>
 
registered with the Commission for resale to the public. In addition, after
the effective date of the Registration Statement, the Company intends to file
a registration statement covering the 2,200,000 shares of Common Stock issued
or reserved for issuance under the Company's 1993 Stock Option Plan and 1998
Stock Option Plan, and, upon filing any shares subsequently issued under such
plans will be eligible for sale in the public market, subject to compliance
with Rule 144 in the case of affiliates of the Company. A decision by any such
stockholder(s) to publicly sell a significant number of shares of the Common
Stock will have the potential to cause a material decrease in the trading
price of the Common Stock and may impair the future ability of the Company to
raise capital at prices or on terms favorable to the Company. See "Shares
Eligible for Future Sale."
 
SUBSTANTIAL DISCRETION OF MANAGEMENT CONCERNING USE OF PROCEEDS
 
  The Company has allocated approximately $30.0 million of the net proceeds of
the Offering for specific identified purposes, with the remainder of
approximately $6.0 million to be used for working capital and general
corporate purposes, including possible acquisitions. Accordingly, management
will have substantial discretion in using a significant percentage of the
proceeds to be received by the Company, and there is no assurance that
management's use of the proceeds can or will yield a return. See "Risks
Related to Strategic Investments or Business Combinations" and "Use of
Proceeds."
 
ANTI-TAKEOVER CONSIDERATIONS
 
  Prior to the completion of the Offering, the Company will adopt an amended
and restated certificate of incorporation and amended and restated by-laws.
Certain provisions of these documents may have the effect of discouraging a
third party from making an acquisition proposal for the Company and thereby
inhibit a change in control of the Company in circumstances that could give
holders of the Common Stock the opportunity to realize a premium over the then
prevailing market price of such stock. Such provisions may also adversely
affect the market price of the Common Stock. Such provisions include, among
other things, a classified Board of Directors serving staggered three-year
terms, the elimination of stockholder voting by consent, the removal of
Directors only for cause, the vesting of exclusive authority in the Board of
Directors to determine the size of the Board of Directors and (subject to
certain limited exceptions) to fill vacancies thereon, the vesting of
exclusive authority in the Board of Directors (except as required by law) to
call special meetings of stockholders and certain advance notice requirements
for stockholder proposals and nominations for election to the Board of
Directors. These provisions, and the ability of the Board of Directors to
issue preferred stock without further action by stockholders, could delay or
frustrate the removal of incumbent Directors or the assumption of control by
stockholders, even if such removal or assumption of control would be
beneficial to stockholders, and also could discourage or make more difficult a
merger, tender offer or proxy contest, even if such events could be beneficial
to the interests of stockholders. The Company will be subject to Section 203
of the General Corporation Law of the State of Delaware which, in general,
imposes restrictions upon certain acquirors (including their affiliates and
associates) of 15% or more of the Company's Common Stock. See "Description of
Capital Stock--Certain Provisions of Certificate of Incorporation and By-laws"
and "Description of Capital Stock--Statutory Business Combination Provision."
 
DIVIDEND POLICY; RESTRICTIONS ON PAYMENT OF DIVIDENDS
 
  The Company has never paid a cash dividend on the Common Stock and does not
anticipate paying cash dividends on the Common Stock in the foreseeable
future. Further, the ability of the Company to pay cash dividends is subject
to contractual restrictions contained in the Credit Facility. See "Dividend
Policy."
 
ABSENCE OF PUBLIC MARKET
 
  Prior to the Offering, there has been no established trading market for the
Common Stock and there can be no assurance that, following this Offering, an
active trading market for the Common Stock will develop or be sustained or
that the market price of the Common Stock will not decline below the initial
public offering price. The initial public offering price will be determined by
negotiations between the Company and the Underwriters
 
                                      17
<PAGE>
 
and will not necessarily be indicative of the market price of the Common Stock
after this Offering. See "Underwriting" for a discussion of the factors to be
considered in determining the initial public offering price. After the
Offering, the market price of shares of Common Stock is likely to be volatile.
The Company believes factors such as actual or anticipated quarterly
fluctuations in financial results, changes in earnings estimates by securities
analysts and announcements of material events by the Company, its customers or
its competitors may cause the market price for the Common Stock to fluctuate.
In addition, in recent years the stock market has experienced extreme price
and volume fluctuations which have affected the market price for many
companies in industries similar to the telecommunications industry and which
have often been unrelated to the operating performance of these companies.
These fluctuations, as well as general economic conditions, may have a
material adverse effect on the price of the Common Stock.
 
DILUTION
 
  Purchasers of the Common Stock offered hereby will experience immediate and
substantial dilution of the net tangible book value of the Common Stock in the
amount of $13.02 per share. To the extent options to purchase the Common Stock
are exercised in the future, there will be further dilution. See "Dilution."
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of 2,500,000 shares of Common
Stock offered by the Company hereby, at an assumed public offering price of
$16.00 per share (the midpoint of the filing range), are estimated to be $36.0
million. Of the net proceeds to be received by the Company, the Company plans
to use (i) approximately $20.0 million to repay amounts outstanding under the
Credit Facility and (ii) approximately $10.0 million for anticipated capital
expenditures, over the next 12 to 18 months, including purchases of new
switches and software, expansion of the Company's facilities and network
infrastructure and implementation of telephony and other related improvements.
The Company entered into the Credit Facility in November 1997 and subsequently
amended such facility in March 1998. The Credit Facility consists of a five-
year revolving credit facility in the amount of $20.0 million. The Credit
Facility expires on December 31, 2002. Funds may be borrowed at either the
bank's base rate plus 1.5% or LIBOR plus 2.75%. The Company has used its
borrowings under the Credit Facility for working capital and capital
expenditures. See "Capitalization" and "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Liquidity and Capital
Resources."
 
  The remaining estimated net proceeds of approximately $6.0 million will be
used for working capital and other general corporate purposes. Such general
corporate purposes include the continued funding of the development and
enhancement of the Company's services and technology and the expansion of its
operations. The Company may also use a portion of the net proceeds to acquire
businesses, technologies, services or products complementary to the Company's
current business, although the Company currently has no agreements or
understandings with respect to any acquisition, and no portion of the net
proceeds has been allocated to specific acquisitions. Pending such uses of the
net proceeds, the Company intends to invest such funds in short-term,
interest-bearing investment grade securities.
 
                                DIVIDEND POLICY
 
  The Company has never declared or paid any cash dividends on its Common
Stock. The Company currently intends to retain its earnings for future growth
and, therefore, does not anticipate paying cash dividends in the foreseeable
future. Payment of future dividends, if any, will be at the discretion of the
Company's Board of Directors after taking into account various factors,
including the Company's financial condition, operating results and current and
anticipated cash needs. In addition, under the terms of the Credit Facility,
the payment of cash dividends generally is prohibited without the consent of
the lenders.

                            CASH AND CAPITALIZATION
 
  The following table sets forth the cash and cash equivalents, current
portion of long-term debt and capitalization of the Company as of December 31,
1997 and as adjusted as of such date to reflect the sale of the 2,500,000
shares of Common Stock offered by the Company hereby (at an assumed public
offering price of $16.00 per share) and the application of the net proceeds
therefrom, after deducting estimated underwriting discounts and offering
expenses payable by the Company. See "Use of Proceeds." This table should be
read in conjunction with "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and Consolidated Financial Statements and
notes thereto appearing elsewhere in this Prospectus.

                                   DILUTION
 
  As of December 31, 1997, Teltrust had a pro forma deficit in net tangible
book value of approximately $6.1 million or a deficit of $0.60 per share of
Common Stock. Pro forma net tangible book value represents the amount of total
tangible assets less total liabilities divided by the number of shares of
Common Stock outstanding, excluding all outstanding stock options. Without
taking into account any other changes in the pro forma net tangible book value
after December 31, 1997, other than to give effect to the receipt by the
Company of the net proceeds from the sale of the 2,500,000 shares of Common
Stock offered by the Company hereby at an assumed public offering price of
$16.00 per share, the pro forma net tangible book value of the Company as of
December 31, 1997 would have been approximately $30.2 million or $2.38 per
share. This represents an immediate increase in pro forma net tangible book
value of $2.98 per share to existing stockholders and an immediate dilution of
$13.02 per share to new investors. The following table illustrates this per
share dilution:

  Other than as noted above, the foregoing computations assume no exercise of

to purchase 1,183,799 shares of Common Stock were outstanding at a weighted
average exercise price of $5.24 per share. To the extent these options or the

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
  The following discussion of the results of operations and financial
condition of the Company should be read in conjunction with the Company's
Consolidated Financial Statements and the Notes thereto included elsewhere in
this Prospectus. This Prospectus contains forward-looking statements.
Discussions containing such forward-looking statements may be found in the
material set forth below and under "Business," as well as elsewhere in this
Prospectus. Prospective investors are cautioned that any such forward-looking
statements are not guarantees of future performance and involve risks and
uncertainties. Actual events or results may differ materially from those
discussed in the forward-looking statements as a result of various factors,
including, without limitation, the risk factors set forth under "Risk Factors"
and the matters set forth elsewhere in this Prospectus.
 
OVERVIEW
 
  Teltrust is a leading independent outsource provider of a broad range of
enhanced call processing and calling card services to the domestic
telecommunications industry. The Company believes that it offers the most
comprehensive suite of services of any independent outsource provider in its
industry. This diversified suite of services includes call completion,
national directory assistance and third-party verification services in
addition to calling card services. Teltrust serves its customers through
state-of-the-art technology and switch-based call processing platforms and, as
of March 1998, more than 1,000 employees. The Company's customers include RBOC
affiliates (such as BSLD and BSPC), pay telephone and hospitality aggregators
(such as Peoples Telephone Company, AMI Telecommunications and Global Net),
IXCs (such as US Long Distance, WorldCom and LCI International), and other
large telecommunications resellers or users (such as TON Services and Eastern
Communications Network). The Company has also recently established contractual
relationships with affiliates of Ameritech Corporation and emerging
telecommunications companies including CLECs (such as Nextlink and Cox Com),
wireless providers (such as Centennial Cellular, Omnipoint Communications and
PowerTel) and international carriers (such as Justice Technology Corp. and
Star Telecommunications). Many customers purchase a number of the Company's
services under multi-year contracts and utilize Teltrust to provide complex
outsourcing solutions. During the quarter ended March 31, 1998, Teltrust
processed over 21 million call processing transactions and decremented more
than 17.6 million domestic minutes for its prepaid calling card customers.
 
  The Company believes the following market factors, among others, create
excellent opportunities for growth as an outsource service provider in the
telecommunications industry. With the continued increase in telecommunications
competition, fostered by the Telecommunications Act of 1996 and subsequent
entry of new providers, an increasing number of telecommunications companies
are seeking to outsource certain functions, such as those provided by
Teltrust, in order to focus capital and other resources on consumer market
penetration and core asset deployment. Also critical to these companies is the
ability to offer differentiated enhanced call processing services to end-
users. Teltrust's growth strategy addresses these two factors by offering
customers the ability to bring enhanced services to market in a more
expeditious and cost-effective manner when compared to building the necessary
infrastructure and expertise to deliver the services internally and enables
customers to focus instead on their core competencies and strategies.
 
  The Company has over 12 years of experience in the telecommunications
industry, its predecessor having been incorporated under the laws of the State
of Utah as Romney & Johnson Company on July 21, 1986. The Company became one
of the largest independent pay telephone providers in Utah by 1988. In 1989,
the Company initiated its call completion services business by installing a
small switch, along with its own dedicated network lines, and obtaining
necessary federal and state regulatory approvals. The Company changed its name
on July 31, 1990 to Teltrust, Inc. Since 1992, the Company has expanded its
service offerings to include national directory assistance, third-party
verification and calling card services. On November 1, 1995, the Company sold
all of the assets of its independent pay telephone business in order to focus
on its enhanced call processing and calling card service businesses. Effective
December 31, 1997, the Company acquired Quest to expand the
 
                                      23
<PAGE>
 
Company's calling card services market and infrastructure. TTST Holdings, Inc.
was incorporated under the laws of the State of Delaware in April 1998.
Following the reorganization of the Company in April 1998, TTST Holdings
changed its name to Teltrust, Inc.
 
  Teltrust's business is primarily transaction-based and operating revenues
are recognized as fees are earned for services performed. Depending on the
application, fees can be based on a variety of factors, including but not
limited to, calls attempted, calls completed, minutes of usage or hours of
service. The Company has a recurring revenue stream from a majority of its
customers. See "Business--Significant Customer Contracts."
 
  The Company's costs of operating revenues consist primarily of compensation
and benefits for service agents, network and telephony costs, the cost of data
for its national directory assistance services and direct overhead costs
associated with generating operating revenues.
 
  Operating expenses consist primarily of salaries, wages and related
benefits, sales and marketing costs, professional fees, legal fees, accounting
fees, rent, insurance and other general expenses including depreciation and
amortization.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
 OPERATING REVENUES
 
  Operating revenues increased $15.9 million, or 39%, to $57.0 million in 1997
from $41.1 million in 1996. Call processing services revenues increased $12.3
million, or 36%, to $46.2 million in 1997 from $33.9 million in 1996. Calling
card services revenues increased $3.6 million, or 49%, to $10.8 million in
1997 from $7.2 million in 1996. The primary reasons for the increased revenues
can be attributed to: (i) additional business volumes with existing customers,
(ii) business with new customers and (iii) a shift to larger contracts with
both new and existing customers.
 
  The Company's three contracts with BSLD and BSPC accounted for approximately
2.7%, 11.9% and 1.6% of the Company's 1997 consolidated operating revenues,
which combined represented 16.2% of the Company's 1997 consolidated operating
revenues. There were no other customers that accounted for more than 10% of
the Company's consolidated operating revenues during 1997. Furthermore, there
were no customers that accounted for more than 10% of the Company's
consolidated operating revenues in 1996. See "Business--Significant Customer
Contracts."
 
 COSTS OF OPERATING REVENUES
 
  Costs of operating revenues increased $16.2 million, or 55%, to $45.5
million in 1997 from $29.3 million in 1996. Approximately $12.7 million of
this increase was associated with the 39% increase in operating revenue during
1997 from 1996 levels. The remaining $3.5 million increase can be attributed
to: (i) a shift in the mix of operating revenues toward more lower-margin
services; (ii) the opening of two new call centers; (iii) increased staffing
and training costs; and (iv) additional network and telephony infrastructure
required for new business that the Company contracted for in 1996 and 1997.
Most of the operating revenues for this new business were not realized in
1997, but are expected to be realized in 1998 and thereafter.
 
 OPERATING EXPENSES
 
  Operating expenses increased $10.1 million, or 74%, to $23.7 million in 1997
from $13.6 million in 1996. This increase was primarily due to: (i) a $2.6
million provision for bad debts in 1997 (as opposed to a $0.8 million
provision for bad debts in 1996); (ii) the write-down of the Company's
investment in, and assets related to, dot.One (formerly Teltrust Data
Services, LLC d.b.a. Teltrust.com), which totaled $1.9 million; (iii) costs
associated with the Company's acquisition of Quest; (iv) increased
depreciation expenses of $ 0.5 million relating to greater capital asset
acquisitions and infrastructure enhancements during 1997; (v) increased
staffing and related compensation and benefits expense consistent with the 39%
growth in 1997 operating revenues; and (vi) increases in operating expenses
attributable to the increased business volume in 1997 and the ramp-up of
programs to accommodate expected future growth based upon new contracts
obtained during 1997.
 
 OTHER EXPENSE
 
  Other expense increased $0.3 million, or 42%, to $1.0 million in 1997 from
$0.7 in 1996. This increase was primarily attributable to increased interest
expense relating to higher borrowing levels in 1997 than in 1996 which was
partially offset by increased interest income on higher average cash and cash
equivalent balances in 1997.
 
 INCOME TAXES
 
  During 1997, the Company's effective income tax rate was less than 1% as a
result of recording a valuation allowance against the deferred tax asset
resulting from the 1997 net operating loss. During 1996, the Company's
effective income tax rate was less than 1% also as a result of recording a
valuation allowance against the 1996 net operating loss which was partially
offset by a benefit resulting from refunds of previously paid income taxes.
 
  Certain of the Company's net operating loss carryforwards ("NOLs") are
limited by ownership changes (as that term is defined in Section 382 of the
Internal Revenue Code of 1986, as amended) that occurred on
 
                                      25

January 21, 1997 and December 31, 1997. See Note 7 to the Consolidated
Financial Statements for a more detailed discussion of the Company's NOLs.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
 OPERATING REVENUES
 
  Operating revenues increased $7.2 million, or 21%, to $41.1 million in 1996
from $33.9 million in 1995. Call processing service revenues rose $4.6 million,
or 16%, to $33.9 million in 1996 from $29.3 million in 1995. The national
directory assistance services and third-party verification services revenues
increased due to increased business with a broader range of customers and
additional revenues being realized from previously secured contracts. Both of
these product lines were in the formative stages in 1995 with revenue growth
accelerating in 1996. Calling card services grew $2.6 million, or 58%, to $7.2
million in 1996 from $4.6 million in 1995. The Company increased its focus and
its sales efforts on larger accounts with longer sales cycles in 1995 and 1996
and was successful in securing a contract with BSLD in November 1996.
 
 COSTS OF OPERATING REVENUES
 
  Costs of operating revenues increased $5.8 million, or 25%, to $29.3 million
in 1996 from $23.5 million in 1995. Approximately $5.0 million of this increase
was associated with the 21% increase in revenue during 1996 from 1995 levels.
The remaining $0.8 million increase is attributable to: (i) the opening of a
second call center and the corresponding increase in staffing and training
costs and (ii) additional network and telephony infrastructure required for new
business that the Company contracted for in 1995 and 1996.
 
 OPERATING EXPENSES
 
  Operating expenses decreased $0.4 million, or 3%, to $13.6 million in 1996
from $14.0 million in 1995. This decrease of $0.4 million was primarily due to
cost reductions by Teltrust during 1996.
 
 OTHER EXPENSE
 
  Other expense increased $0.1 million, or 16%, to $0.7 million in 1996 from
$0.6 million in 1995. This increase was primarily attributable to increased
interest expense relating to higher borrowing levels in 1996 than in 1995 which
was partially offset by increased interest income on higher average cash and
cash equivalent balances in 1996.
 
 INCOME TAXES
 
  During 1996, the Company's effective income tax rate was less than 1% as a
result of recording a valuation allowance against the deferred tax asset
resulting from 1996 net operating loss which was partially offset by a benefit
resulting from refunds of previously paid income taxes. During 1995, the
Company's net effective income tax rate (after combining the benefit from
income taxes with the income tax provision for the discontinued operations and
gain on disposal) was 2%. This net income tax provision primarily resulted from
the Company's alternative minimum tax liability. During 1995, the Company
provided a valuation allowance against the deferred tax asset resulting from
the 1995 net operating loss.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's liquidity requirements consist primarily of working capital
needs, capital expenditures and payments of interest on its Credit Facility.
The Company's working capital requirements have increased largely as a result
of higher accounts receivable due to increases in operating revenues. In
addition, the Company has purchased and deployed additional property and
equipment in anticipation of future operating revenue growth.
 
 
                                       26
<PAGE>
 
  Teltrust had a negative $6.0 million working capital position at December
31, 1997 compared with a negative $1.7 million working capital position at
December 31, 1996. This $4.3 million change in working capital was primarily
due to the net loss the Company incurred in 1997.
 
  The Company has a $20.0 million secured operating line of credit with Fleet
National Bank (the "Credit Facility"). The Credit Facility expires September
30, 2002 but is subject to quarterly reductions in the commitment amount
beginning March 31, 1999 in the following amounts: (i) 3.0% per quarter in
1999; (ii) 5.625% per quarter in 2000; (iii) 9.0% per quarter in 2001; and
(iv) 9.833% per quarter in 2002. Under the terms of the Credit Facility,
outstanding borrowings bear interest at the bank's base rate plus 1.5% or the
LIBOR rate plus 2.75%, although, these rates can change based upon the ratio
of total debt to EBITDA. Availability under the Credit Facility is subject to,
among other things, compliance with loan covenants. The Credit Facility
contains certain restrictive covenants such as: (i) minimum EBITDA
requirements; (ii) minimum interest and debt service coverage ratios; (iii) a
minimum fixed charge coverage ratio; (iv) a capital expenditures limitation;
and (v) a prohibition against the payment of cash dividends. The Credit
Facility is secured by a first priority perfected security interest in all
assets of the Company in addition to a pledge of the capital stock of Holdings
and its subsidiaries. As of December 31, 1997, the Company had advances under
the Credit Facility of $12.1 million with an effective interest rate of 8.8%.
 
  As of December 31, 1997, the Company had $0.5 million in cash and cash
equivalents compared to a total of $8.5 million in cash and cash equivalents
and restricted cash at December 31, 1996, a decrease of approximately $8.0
million resulting primarily from the Company's net losses, the expansion of
the Company's switch and network infrastructure, and the addition of two new
call centers.
 
 CASH FLOWS FROM OPERATING ACTIVITIES
 
  Net cash used by operating activities for the year ended December 31, 1997
was $6.7 million, resulting primarily from the net loss for 1997 of $13.2
million. The impact of the net loss was mitigated in part by increases in
current liabilities of $7.2 million, depreciation and amortization of $2.0
million, provision for doubtful accounts of $3.6 million and loss on writedown
of joint venture of $0.8 million which were partially offset by increases in
receivables of $6.6 million due to longer payment terms on larger contracts.
 
  Net cash used by operating activities for the year ended December 31, 1996
was $3.4 million, resulting primarily from the net loss for that period. The
impact of the net loss was mitigated in part by depreciation and amortization
of $1.5 million and provision for doubtful accounts of $0.8 million and an
increase in receivables of $2.0 million. The use of cash by operating
activities in 1995 was primarily due to the Company's net loss of $2.0
million. The net loss was mitigated in part by depreciation and amortization
of $1.4 and a provision for doubtful accounts of $0.5 million and increased by
(i) increases in accounts receivable of $1.2 million and (ii) decreases in
current liabilities of $1.5 million and a gain not relating to operating
activities of $1.6 million. The gain related to the disposal of the assets of
the Company's pay telephone business in November 1995.
 
 CASH FLOWS FROM INVESTING ACTIVITIES
 
  Cash used in investing activities was $3.2 million for 1997 and was related
primarily to $7.2 million of capital expenditures for new switch and computer
equipment, software, operator stations, furniture and leasehold improvements
for new call centers which was partially offset by use of $4.0 million in cash
restricted pursuant to the Company's sale of preferred stock. During the year
ended December 31, 1997, approximately $1.0 million of capital equipment was
acquired through lease financing.
 
  Cash used in investing activities was $5.7 million in 1996 and was related
primarily to capital expenditures for equipment upgrades and expansion. During
the year ended December 31, 1996, approximately $1.9 million of capital
equipment was acquired through lease financing. In addition, $4.0 million of
the proceeds from the Company's sale of preferred stock was restricted for
capital expenditures. Net cash provided by investing activities in 1995 was
$2.5 million. Approximately $1.1 million was used for the purchase of
equipment which
 
                                      27
<PAGE>
 
was offset by proceeds from the sale of the Company's pay telephone operations
for $3.7 million. Capital equipment acquired through lease financing was $0.5
million during the year ended December 31, 1995.
 
 CASH FLOWS FROM FINANCING ACTIVITIES
 
  Net cash provided from financing activities for the year ended December 31,
1997 was $8.9 million resulting primarily from $12.1 million in borrowings
under the Company's line of credit which was established in November 1997, the
use of $2.9 million of restricted cash to repurchase common stock and retire
debt and $0.8 million from the exercise of warrants, offset by $3.1 million in
notes payable that were retired in conjunction with the Quest acquisition,
$2.4 million in payments made to repurchase the Company's common stock and
$1.5 million in other debt and capital lease obligations that were retired.
 
  Net cash provided from financing activities for the year ended December 31,
1996 was $10.2 million resulting primarily from $14.5 million of proceeds from
the sale of preferred stock, $1.5 million from the issuance of notes relating
to Quest and $0.5 million of proceeds from the issuance of subordinated notes
payable offset by $3.1 million in notes that were retired during 1996 and $0.3
million in capital lease obligations that were retired. In addition, $2.9
million of the proceeds from the sale preferred stock was restricted for the
retirement of debt.
 
  Net cash provided from financing activities for the year ended December 31,
1995 was $3.0 million resulting primarily from the issuance of $4.9 million in
notes payable net of $1.5 million in notes that were retired in 1995 and $0.4
million in capital lease obligations that were retired.
 
 FUTURE CAPITAL NEEDS AND RESOURCES
 
  The Company expects to incur approximately $7.8 million in capital
expenditures during 1998 for: (i) additional switches, (ii) software, (iii)
network capability, (iv) telephony infrastructure and (v) the expansion and
improvement of the Company's facilities including its corporate offices and
call center operations. The Company will also use capital to repay principal
and interest on indebtedness.
 
  The Company believes that its existing cash and cash equivalents,
availability under the Credit Facility and expected cash from operations will
be sufficient to fund its operating activities at least through the end of
1998. See "Risk Factors--Future Needs for Additional Financing."
 
IMPACT OF INFLATION
 
  Teltrust does not consider inflation to have had a material impact on the
results of operations for the years ended December 31, 1995, 1996 and 1997.
 
YEAR 2000 COMPLIANCE
 
  The Company believes that it has achieved substantial compliance on all
systems and software utilized in its operations. At present, the fraud control
systems at each of the Company's sites are not yet Y2K compliant. However,
each of the systems is being upgraded, with a target compliance date of
September 1998. The Company expects its total cost to achieve Y2K compliance
to be between $100,000 and $150,000. See "Risk Factors--Year 2000 Compliance"
and "Business--Operations and Technology--Year 2000 Compliance."
 
SEASONALITY
 
  The Company's business follows the seasonal trends of its customers'
businesses. The Company generally experiences lower operating revenues during
the first and fourth quarters of each calendar year due to seasonal travel and
vacation patterns and reduced sales efforts by the Company's customers.

                                   BUSINESS
 
  Teltrust is a leading independent outsource provider of a broad range of
enhanced call processing and calling card services to the domestic
telecommunications industry. The Company believes that it offers the most
comprehensive suite of services of any independent outsource provider in its
industry. This diversified suite of services includes call completion,
national directory assistance and third-party verification services in
addition to calling card services. Teltrust serves its customers through
state-of-the-art technology and switch-based call processing platforms and, as
of March 1998, more than 1,000 employees. The Company's customers include RBOC
affiliates (such as BSLD and BSPC), pay telephone and hospitality aggregators
(such as Peoples Telephone Company, AMI Telecommunications and Global Net),
IXCs (such as US Long Distance, WorldCom and LCI International), and other
large telecommunications resellers or users (such as TON Services and Eastern
Communications Network). The Company has also recently established contractual
relationships with affiliates of Ameritech Corporation (ACI and ASI) and
emerging telecommunications companies including CLECs (such as Nextlink and
Cox Com), wireless providers (such as Centennial Cellular, Omnipoint
Communications and PowerTel) and international carriers (such as Justice
Technology Corp. and Star Telecommunications). Many of the Company's customers
purchase a number of the Company's services under multi-year contracts and
utilize Teltrust to provide complex outsourcing solutions. During first
quarter ended March 1998, Teltrust processed over 21 million call processing
transactions and decremented more than 17.6 million domestic minutes for its
prepaid calling card customers.
 
INDUSTRY OVERVIEW
 
  During the 1990s, changes in the regulatory environment and the emergence of
new technologies have created a growing and fiercely competitive environment
in the telecommunications industry. As a result, telecommunications companies,
including RBOCs, IXCs, LECs, CLECs and wireless providers, are evaluating
their existing services and seeking opportunities that will allow them to
compete more effectively, reduce operating costs, and increase usage, market
penetration and customer retention. Many of these companies are seeking access
to call completion services, national directory assistance services and
calling card platforms which are considered essential by end-users. Partnering
with an outsource provider, such as Teltrust, allows telecommunications
companies to bring new value-added products and services to market in a more
expeditious and cost-effective manner than by building the necessary
infrastructure to provide such services internally and enables
telecommunications companies to focus on their core competencies and
strategies. Additionally, such consumer service providers, through
outsourcing, are able to focus capital and other resources on marketing, in
addition to building and maintaining switching and network capacity. The
Company believes that an increasing number of telecommunications companies
consider outsourcing a critical element in executing their business plans as
evidenced by the emergence of growing numbers of third-party billing, customer
care and calling card service providers.
 
  According to FCC reports, the telecommunications market in the United
States, including local, long distance, wireless and prepaid calling,
comprised an overall market estimated at more than $220 billion in 1996. In
addition, CLEC and wireless markets are growing at rates in excess of the
telecommunications industry as a whole, thus attracting new entrants into
those markets. As a result, the competitive environments in which
telecommunications companies compete for market share are being reshaped,
placing increasing demands on these companies to establish and differentiate
themselves in order to penetrate new markets and retain existing business.
Outsourcing allows new entrants in the telecommunications industry to
accomplish these goals without incurring extensive capital expenditures.
 
TELTRUST'S COMPETITIVE ADVANTAGES
 
  Teltrust provides telecommunications companies with a broad range of
flexible and cost-effective solutions to their call completion, national
directory assistance, third-party verification service and calling card needs.
The Company believes that its services allow its customers to: (i) offer new,
value-added services to their retail customers, (ii) expand and enhance
traditional services such as agent-assisted, calling card and directory
assistance calling, (iii) reduce capital expenditures and operating costs
through outsourcing, and (iv) differentiate themselves in markets in ways that
enhance brand recognition and customer loyalty.
 
                                      29
<PAGE>
 
  The Company believes that the following constitute key competitive
advantages in its ability to successfully market and deliver to its customers
and potential customers the enhanced call processing and calling card services
they need:
 
 FOCUS ON PROVIDING WHOLESALE OUTSOURCE SERVICES
 
  Teltrust offers its diversified suite of enhanced call processing and
calling card services on a wholesale basis to companies in the
telecommunications industry. The Company's ability to provide a diversified
suite of outsource services to its customers distinguishes Teltrust from most
of its competitors who provide a more limited range of services. In addition,
unlike many other providers of call processing services, the Company does not
compete with its customers in their core businesses or target the end-users of
their products and services. Because Teltrust does not engage in mass market
operations, it is able to direct its service, technical and other resources
toward offering and developing a broad array of enhanced call processing and
calling card services to telecommunications companies. The Company believes
that telecommunications companies are increasingly seeking to outsource
functions to specialized third-party service providers, particularly those who
can offer a wide array of services.
 
 PROVEN AND FLEXIBLE OPERATING INFRASTRUCTURE AND TECHNOLOGY
 
  The Company's advanced technology and infrastructure has met and continues
to meet the rigorous service performance standards of its customers. The
Company believes its proven infrastructure and technology are key
differentiating factors in furthering existing relationships and attracting
new customers. In addition, the Company's flexible infrastructure allows it to
customize services to meet its customers' changing needs. The call processing
software resident in its switch platforms offers flexible call treatment and
routing options, and the search engine technology utilized in national
directory assistance services offers enhanced search capabilities and service
agent responsiveness. Components of the Company's call completion platforms
and calling card platforms are proprietary and have been developed to offer a
highly versatile approach to service delivery and have been tested over
several years of operations.
 
 EXCELLENCE IN CUSTOMER SERVICE
 
  Teltrust is committed to providing excellent service to its customers and
strives to respond to their individual needs. For example, many of Teltrust's
customers need to provide call processing and calling card services to end-
users who do not speak English. The Company believes that its ability to offer
service to its customers in over 20 foreign languages has been an important
factor for many of its customers in choosing Teltrust as its service provider.
Teltrust's customer support staff works closely with its customers to
establish quality standards and tailor the Company's services to meet the
individual needs of such customers. Service representatives participate in
extensive training that emphasizes courtesy, accuracy and time of response to
callers.
 
 DEMONSTRATED PERFORMANCE AND EXPERIENCE
 
  Since its founding in 1986, Teltrust has developed the infrastructure,
technology and operating methods and procedures necessary to secure ongoing
relationships with telecommunications companies. The Company provides reliable
and high quality enhanced call processing and calling card services as
measured against the stringent contractual performance standards that its
customers demand. The Company believes this experience has positioned it as a
recognized provider of high quality services and has enabled it to attract
customers such as BSLD, BSPC, ACI and ACS, LCI International, Cox Com and
Nevada Bell. Additionally, the Company believes its demonstrated performance
for existing clients has prompted such clients to turn to the Company to
fulfill their expanding service needs.
 
TELTRUST'S GROWTH STRATEGY
 
  Teltrust's goal is to be the premier provider of outsourced enhanced call
processing and calling card services. The key elements of the Company's
focused growth strategy are as follows:
 
 
                                      30
<PAGE>
 
 CROSS-SELL TO EXISTING CUSTOMERS
 
  The Company is focusing on expanding current customer relationships by
cross-selling additional services. The majority of the Company's customers
require many or all types of services the Company provides as part of its end-
user service offerings. Local, long distance and wireless providers offer call
completion and national directory assistance as standard services to their
retail customers, and many also offer prepaid calling card programs. In
addition, many of the Company's customers operate in regulated environments
requiring third-party verification of new service orders. The Company has been
successful in forming relationships in which its customers purchase one or,
more frequently, a combination of the Company's enhanced call processing and
calling card services. In some instances, network connectivity between the
Company and a particular customer for a single service can be utilized for the
provision of additional services, increasing operating efficiencies for the
customer, the Company, or both.
 
 SECURE NEW CUSTOMERS
 
  The Company is expanding its customer base by continuing to target RBOCs,
IXCs, LECs, CLECs, wireless providers and others that are not currently
customers. Such companies are seeking cost-effective and flexible ways to
provide enhanced services such as those offered by Teltrust to distinguish
themselves in retail markets. The Company intends to use its operating
experience, product strength and position in the marketplace to capture
increased market share and become the leading provider of outsourced enhanced
call processing and calling card services. The Company also intends to
generate growth by expanding its current service offerings to new markets.
Further, as deregulation continues and competition expands in international
telecommunications markets, the Company intends to offer its suite of call
processing and calling card services to international carriers. In addition,
deregulation of the public utility industry may lead to opportunities to
utilize the Company's third-party verification services in new markets.
 
 DEVELOP ADDITIONAL SERVICES
 
  The Company believes that telecommunications companies seeking to outsource
call processing and calling card functions will increasingly rely on full-
service outsource providers who can offer a broad array of high-quality
services. To meet this demand, the Company intends to continue to expand the
types of services it offers to meet its customers' expanding needs. One
current example of a new service is the Company's proprietary B.O.S.S.TM
system which expedites carrier change orders. Possible additional service
offerings could include international directory assistance and enhanced
calling card features such as conferencing, "follow me/find me" service and
speed-dialing.
 
 MAINTAIN HIGH LEVELS OF CUSTOMER SATISFACTION
 
  The Company intends to continue to provide superior customer service in
order to maintain and enhance its reputation as a leading independent provider
of outsourced call processing and calling card services. By responding to the
individual needs of customers, tailoring its services to those needs and
delivering its services professionally and efficiently, the Company believes
it will continue to be regarded as a high quality provider of such services.
 
 LEVERAGE OPERATING INFRASTRUCTURE
 
  Teltrust's operational structure provides opportunities to realize operating
leverage as the Company expands its business to meet the needs of current and
future customers. The Company currently operates 14 switches at 11 locations
in five cities, maintains network facilities in 24 states, operates four
service agent centers and employs, as of March 1998, more than 1,000 people.
In 1997, the Company upgraded and expanded certain switch sites and invested
in additional service agent centers. The flexible architecture of the
Company's infrastructure facilitates network connectivity between Teltrust and
its customers. Once it establishes a connection in order to provide a service
to a customer, the Company is often able to leverage this relationship to
provide additional services with the existing network connection.
Additionally, the Company has significant infrastructure capacity. As a
result, the Company can realize greater efficiencies through growth in its
business.

 CONSIDER STRATEGIC ACQUISITIONS
 
  The Company's business strategy includes consideration of strategic
acquisitions in complementary and existing business areas, which may
facilitate more effective and rapid development of a broader array of services
or expansion of existing services than developing these service capabilities
internally. As an example, the Company's acquisition of Quest expanded
Teltrust's presence in the calling card services market and enhanced its
technology base.
 
DESCRIPTION OF TELTRUST SERVICES
 
 ENHANCED CALL PROCESSING SERVICES
 
  Teltrust provides its customers with a variety of enhanced call processing
services. These services provide the Company's customers the ability to
distinguish themselves in mass markets, bring products and services to market
faster and reduce operating costs. The Company's suite of enhanced call
processing services includes (i) call completion services, (ii) national
directory assistance and (iii) third-party verification services.
 
  CALL COMPLETION SERVICES. The Company provides call completion services to
many sectors of the telecommunications industry, including RBOCs, IXCs, LECs,
CLECs, wireless providers, pay telephone and hospitality aggregators,
telecommunications resellers and international carriers. Customers of the
Company's call completion services include RBOC affiliates, such as BSPC and
BSLD; pay telephone and hospitality aggregators, such as Peoples Telephone
Company, Global Net and AMI Telecommunications; and IXCs, such as Access Long
Distance and Tel America/Kenna Communications. The Company also recently
entered into an agreement with an affiliate of Ameritech Corporation and
emerging telecommunications companies including CLECs, such as Cox Com and
Comcast Telecommunications. Teltrust's call completion services consist of
automated or live agent assisted calling card calling, collect calling and
third-party billed calling. The Company generally earns revenues from its call
completion services customers on a per-completed call, per call-attempt or
per-minute-of-use basis.
 
  The Company's call completion services are delivered through the use of
state-of-the-art automated call processing platforms and highly trained
service agents. The Company provides call completion services from call
processing platforms located in Salt Lake City, Atlanta, Los Angeles, Miami,
and New York City, and from three service agent centers located in Salt Lake
City. Call completion services are accessed when users dial proprietary 1-800
numbers (e.g. 1-800-BELLSOUTH(TM) or 1-800-AMERITECH(TM)), 0 + area code and
phone number or 00 or 0. Calls being transported to Company facilities for
call completion services are dependent on network routing, programming of
premise equipment, or customer switch to Company switch connections.
 
  When a call is routed to Company telecommunications switches for service,
databases are accessed to determine the type of service(s) to be provided.
Switching databases capture the incoming circuit identification, and the line
number (i.e., the phone number) from which a call was originated. Customer
specific configurations are implemented at the time of service initiation
based on customer requirements. These configurations instruct switching
systems how to treat a call based on circuit identification and/or line
number. The Company's switching databases employ extensive use of local and
wide area networks and are centrally managed from the Company's headquarters
in Salt Lake City. See "Business--Operations and Technology."
 
  In conjunction with providing call completion services, the Company also
offers STATUS(TM), a proprietary refund and repair service that enables
callers who are experiencing difficulty in completing a call or who may have
lost money at a pay telephone to register their complaint and either arrange
to receive a cash refund or have their call completed at no charge (or free
call completion service). Each call that identifies a problem with a telephone
location results in a "trouble ticket" being posted on an electronic bulletin
board to enable the Company's customer to retrieve the information and take
corrective measures. The Company has developed a sophisticated fraud control
system in conjunction with its free call completion service, without which
system the offering of free calls would entail a high degree of risk of
fraudulent abuse of the system. Customers who utilize the Company's free call
completion service are able to realize substantial savings by avoiding the
expense of
 
                                      32
<PAGE>
 
mailing small refund checks, and they are able to minimize their risk of
losses from callers abusing the system by making repeated requests for free
calls. Among the Company's clients utilizing this service are Peoples
Telephone Company and Nevada Bell.
 
  One of the Company's advantages in the marketplace is its ability to offer
multiple services from a single platform. In addition to traditional calling
card, collect or third-party call options, the Company can implement enhanced
service options for its customers. For example, a customer may wish to offer
their telecommunications cardholders the ability to access national directory
assistance or customer service, in addition to traditional call completion
options, by dialing "0" or a proprietary "1-800" number. The Company believes
its ability to integrate service offerings in this fashion provides a
competitive advantage.
 
  According to industry reports, it is estimated that calling card or agent-
assisted calls generate more than $13.0 billion in revenue per year. The vast
majority of these calls are handled by the major IXCs, such as AT&T, MCI and
Sprint, the RBOCs and GTE. Over the last five or more years, the
telecommunications industry has seen a significant transition to "access code"
calling, such as 1-800-BELLSOUTH(TM). These calls, handled by automated
platforms or live operators, are generally billed to IXC- or LEC-issued
calling cards or are collect or third-party billed. Many second and third tier
IXCs, as well as CLECs and wireless communications providers, simply route
these calls, from their telephony switches, to the major IXCs or RBOCs for
call completion, instead of building the necessary infrastructure to handle
such calls. Historically, these calls were placed by consumers dialing "0"
plus the area code and the number to which they wished to be connected.
 
  With increased competition in telecommunications markets, many
telecommunications companies seek a more economical way to provide call
completion services to end-users, and expect increased flexibility and
functionality in the platforms and operators who provide such services. The
Company has developed and deployed systems, technology, management and trained
service agents to deliver a broad range of call completion services. These
services are distinguished by branding capabilities and enhanced functionality
resident in platforms to which such "0" or "1-800" calls are routed.
 
  NATIONAL DIRECTORY ASSISTANCE SERVICES. The Company currently provides
national directory assistance services to many sectors of the
telecommunications industry including RBOCs, IXCs, LECs, CLECs, wireless
providers, pay telephone and hospitality aggregators, telecommunications
resellers and international carriers. Customers of the Company's national
directory assistance services are telecommunications aggregators, such as
Eastern Communications Network, and IXCs, such as US Long Distance (recently
acquired by LCI International), Total Tel and Coastal Telephone. The Company
has also established relationships with wireless providers, such as Omnipoint
Communications, CellularOne of Springfield, Centennial Cellular and PowerTel,
and CLECs, such as Cox Com. Teltrust provides national directory assistance
service covering the entire United States, Puerto Rico and the United States
Virgin Islands. The Company earns revenues from its national directory
assistance operations on a per-call basis.
 
  One of the advantages of the Company's national directory assistance
services is that a user does not need to know the area code for the listing
being requested. This is an important feature given the recent proliferation
of new area codes throughout the United States. Under traditional directory
assistance service models, if a user dialed 213-555-1212 to find a listing in
Los Angeles, but the desired listing was in the 310 area code, the user would
need to hang up and dial 310-555-1212 to access the listing. Teltrust's
national directory assistance services can provide the 310 listing even if the
user dialed 213-555-1212. Additionally, listings can be provided for different
geographic regions during the same call.
 
  Teltrust's national directory assistance service has a number of enhanced
features, including automated national directory assistance call completion
services. A user has the option, after having received the listing, of
automatically being connected to the listing received. The Company's wireless
provider customers, in particular, find this option attractive in enhancing
"ease of use" for their subscribers. Industry estimates indicate that by the
year 2000 calls placed through wireless providers will account for 50% of all
directory assistance calls. The Company's national directory assistance
services can also provide reverse search listings to an end-user who has a
phone number for which a name listing is sought. Additionally, the Company's
systems can provide listings
 
                                      33
<PAGE>
 
based on a single key word search criterion. For example, if an end-user is on
California Street in San Francisco, and is looking for the nearest flower
shop, national directory assistance can provide a listing by searching on the
entry "flower" and the entry "California Street" in San Francisco. In
addition, the Company's national directory assistance services can perform
searches by standard industrial classification code.
 
  The Company utilizes a leading national database provider to supply the data
used by the Company in providing national directory assistance services.
Additionally, the Company has access to Electronic Directory Assistance
databases maintained by LECs. Access to such data enhances the Company's
accuracy in providing listings to callers and provides it with a competitive
advantage in the marketplace.
 
  In late 1997, the Company invested in substantial system upgrades to further
enhance its national directory assistance services. The upgrades are expected
to provide additional value-added service components to the existing national
directory assistance service, reduce Company operating costs by providing
additional staff management tools and enhancing system interface for service
agents and provide the Company with the ability to offer a stratified product
set to meet its customers' demands.
 
  According to industry reports, it is estimated that directory assistance
calls generate more than $1.5 billion in revenue per year. The directory
assistance market has historically been primarily served by the RBOCs and
other traditional LECs such as GTE. Only recently has the market seen IXCs and
other directory assistance companies provide this service. This is due to the
fact that the RBOCs and LECs issue a phone number when local service is
initiated for a residence or business and therefore have been the parties who
control and maintain the data regarding phone numbers and addresses. The RBOCs
and LECs operate directory assistance centers within their respective regions
and ultimately handle most calls needing a directory listing for residences or
businesses served by that RBOC or LEC. This historically included providing
service to IXCs and wireless providers. For example, if a long distance
carrier customer dialed information for a listing in another state, the long
distance carrier would typically route that call to the LEC that provided
local service to that listing.
 
  With the advent of national listing databases, long distance and wireless
providers have an alternative and can begin to purchase directory assistance
service from new competitive providers. During recent years, the market has
seen companies develop comprehensive and updated national listing databases,
followed by companies who set up operations to utilize such data for directory
assistance resale. These databases are typically comprised of any number of
input sources, including white and yellow page listings and the purchase of
RBOC and LEC data.
 
  The demand for competitive directory assistance service has grown in recent
years, in large part due to increased competition among established local and
long distance carriers and wireless providers, as well as new entrants in each
of these markets. Telecommunications companies are looking to single source,
competitive alternatives to provide their retail customers with national
directory assistance, complemented by enhanced services. The introduction of
national "411" directory assistance by some of the RBOCs has heightened
consumer awareness of national directory assistance, and has set the stage for
local competitors also requiring a national product. Competition in the
directory assistance marketplace has also spurred innovation and resulted in
increased functionality of directory assistance platforms, above and beyond
the typical playback of a listed number. For many companies, a single source,
national provider can reduce network interconnection costs and provide branded
service, something historically not available from the RBOCs and LECs. The
Company has established key relationships with data providers and deployed
highly technical database interface software to take advantage of this trend,
with the goal of becoming the premier national directory assistance provider
in its markets.
 
  THIRD-PARTY VERIFICATION SERVICES. The Company is one of the leading
independent providers of third-party verification services to
telecommunications companies in the United States. The Company recently
expanded operations into a new service agent center with 250 stations
dedicated to its third-party verification services. Utilizing a strong
management team and sophisticated call management and digital recording
technology, the Company provides third-party verification services to all
sectors of the telecommunications industry. Customers utilizing the Company's
third-party verification services include IXCs, such as LCI
 
                                      34
<PAGE>
 
International and WorldCom, and telecommunications resellers, such as The
Furst Group and Cydcor. The Company also recently entered into agreements to
provide third-party verification services to an RBOC affiliate, US West
Communications, CLECs, such as Cox Com and Comcast Telecommunications and
international carriers, such as Star Telecommunications and RSL Com U.S.A.
 
  Third-party verification is an FCC requirement designed to protect consumers
from a practice known as "slamming," which is the unauthorized switching of an
end-user's IXC or LEC without first obtaining the consent of the end-user.
Slamming first emerged as a significant problem in the late 1980's and early
1990's with the emergence of significant competition in the long distance
marketplace. Hundreds of new long distance carriers and resellers began
competing with AT&T through a variety of innovative marketing approaches
including telemarketing. The increase in competition in the long distance
marketplace benefited end-users by lowering long distance charges
significantly, but it also created an environment that made slamming all too
common. By 1996, the FCC and many state PUCs received more complaints
regarding slamming than any other issue.
 
  To deter slamming, in 1992 the FCC ordered all IXCs to implement one of four
procedures to verify long distance service change orders generated by
telemarketing. The four alternatives are: (i) obtain a written Letter of
Agency from the end-user; (ii) receive confirmation from the end-user via a
toll-free number provided exclusively for the purpose of confirming change
orders electronically; (iii) use an independent third party to verify the end-
user's order; or (iv) send an information package that includes a postpaid
postcard which the end-user can use to deny, cancel or confirm a service
order, and wait 14 days after mailing the packet before submitting the
preferred IXC change order. Because the third option, the use of an
independent third party to verify an end-user's order, is the quickest way to
effect the change to an end-user's preferred IXC, most IXC's have adopted this
option when telemarketing their services. It is estimated that more than 40
million third-party verification transactions were processed in the United
States in 1997. With the passage of the Telecommunication Act of 1996 and the
emergence of telecommunications competition in local markets, Congress, the
FCC, state PUCs and numerous other consumer protection organizations have
begun to evaluate the need to implement third-party verification and other
anti-slamming measures on a broader scale than is currently in place in the
long distance marketplace. For example, the FCC has proposed to amend its
rules to apply the four verification procedures described above to changes in
local exchange, as well as long distance, services.
 
  In addition to the FCC's efforts to expand verification requirements to all
carriers, several state PUCs have implemented anti-slamming rules, which the
Company believes will result in the increased need for the Company's third-
party verification services. For example, on January 1, 1997, the State of
California implemented rules that expanded the requirements for third-party
verification services by requiring that an independent third-party
verification company verify any residential subscriber carrier change, no
matter how the carrier marketed its services to the residential consumer.
Numerous other states have either implemented new verification requirements or
are in the process of implementing verification requirements to combat
slamming.
 
  The Company believes third-party verification services will benefit from
regulatory changes taking place in the United States telecommunications
industry. Third-party verification should become increasingly important as
telecommunications competition increases at the local level. The Company
believes that deregulation in other monopoly markets such as gas and electric
utilities may also create new demand for third-party verification services
beyond the telecommunications industry.
 
 CALLING CARD SERVICES
 
  The Company's calling card services are provided through two applications:
wholesale service applications and co-branded applications. Wholesale service
applications customers purchase network and platform services from the Company
on a "minutes of use" basis. Such customers have their own distribution or
end-user bases in place and outsource the telecommunications carriage and
technology provision. Certain customers, including IXCs, CLECs and others, may
utilize an existing network and simply route calls over that network to the
Company's platforms, paying the Company solely for the use of its call
processing technology. The Company
 
                                      35
<PAGE>
 
also works closely with its customers to offer additional enhanced services to
end-users. Customers of co-branded service applications purchase cards from
the Company at a discount from retail value. Customers in this market segment
are generally retail chains who wish to offer patrons prepaid calling cards in
their name. Customers utilizing the Company's calling card services include
TON Services (an affiliate of one of the largest operators of truck stop
fueling and convenience facilities in the United States) and ACI. In co-
branded service applications, the Company provides services to retailers, such
as Heilig Myers and El Amal, a Puerto Rico-based convenience and drug store
chain.
 
  All customers have access to state-of-the-art point-of-sale activation
technology, offering users quick, convenient activation of accounts. The
Company also can supply ready-to-use displays for its customers' outlets.
Customers are able to leverage the Company's technology to offer end-users
multiple services from a single access point. Enhanced services available as
part of the Company's calling card services include: voice mail, fax
capabilities, the ability to purchase other types of products, and access to
weather and stock market reports. The Company's technology also provides its
customers with the ability to quickly refresh cards for re-use.
 
  Point-of-sale activation and refresh technology is a critical component of
prepaid calling card services. Generally, cards are either "active" on the
shelf or activated by swiping an exposed magnetic strip at the time of end-
user payment. Such programs generally utilize cards carrying certain
denominations of value, such as $10, $25 or $50. The Company has developed
technology allowing retail locations to stock cards that carry no pre-
determined denomination or value. The end-user elects how much credit to
purchase, and upon remittance of payment, the card is swiped through a cash
register or credit card verification machine, and instantly activated in the
Company's platforms. Cards can be refreshed either at a point of sale or
through a customer service agent over the telephone. The Company is also
deploying postpaid applications utilizing its technologically advanced
existing prepaid platforms. The Company's objective is to provide a robust,
flexible calling card platform giving Teltrust customers the ability to offer
a broad range of services with flexible payment options.
 
  Prepaid calling cards have been widely accepted and used for many years
outside of the United States and have become an increasingly accepted method
of payment for away from home calling over the last four years in the United
States. The prepaid calling card segment is now one of the fastest growing
segments in the telecommunications industry and is estimated in industry
reports to be a $2.0 billion market by 2000. Prepaid calling cards allow the
consumer to purchase a pre-determined amount of calling value. Cards are
usually purchased in grocery stores, drug stores, convenience stores and other
retail locations. A prepaid calling card enables a consumer to place local,
long distance and international calls from virtually any touch tone phone.
Callers dial special "1-800" numbers, are prompted for a card number and PIN,
and then given access to Company platforms for a variety of service options.
End-users in the United States are increasingly finding prepaid calling cards
advantageous and convenient. With prepaid calling cards, users receive no
monthly billing statement, can purchase and refresh cards by purchasing
additional minutes based on their calling needs, and the risk of fraud or
theft is limited to the purchased amount of time on the card.
 
  In December 1997, the Company completed the acquisition of Quest and
combined its calling card operations with those of the Company. Quest is a
ten-year old company and over the last five years has been a pioneer in the
United States prepaid calling card market, being one of the first prepaid
service companies to be fully tariffed for service provision in the entire
United States. Quest has developed and deployed sophisticated and flexible
proprietary technology, utilizing Harris Digital Telephone Systems ("Harris")
telephony switches similar to those used by the Company. The Company believes
the acquisition will enable it to offer its customers a broader range of
services, position it for additional growth and enhance the Company's focus on
the ongoing growth of prepaid and postpaid calling card revenues and profits.
The Quest transaction was the Company's first acquisition and was executed as
a strategic expansion of an existing service. Certain economies of scale are
anticipated to be realized from the acquisition, including purchasing power
relative to network transmission, the primary cost in the provision of prepaid
services.

SALES AND MARKETING
 
  The Company markets its services through its executive management, sales
management, customer support and marketing teams. Executive level personnel
are based in Salt Lake City and Atlanta, and the Company has sales
representatives in several other locations in the United States. Sales and
marketing strategies focus on leveraging initial service contacts to include
additional services and often cross multiple vertical markets, taking
advantage of the Company's diversified suite of services.
 
  Product management teams facilitate the Company's marketing strategies
through: (i) market research performed in-house and by outside specialty
firms; (ii) evaluations of the Company's product lines vis-a-vis its
competition; (iii) product enhancements required to meet vertical market
demands; and (iv) product development recommendations to meet short and long-
term marketing and profitability goals.
 
  In Salt Lake City, the Company's sales force is comprised of three sales
executives and five sales professionals. This staff focuses primarily on the
following markets: RBOCs, IXCs, LECs, CLECs, wireless providers and calling
card service providers. In Atlanta, the Company has a sales executive and
professional staff focused on the calling card services market. Additionally,
the Company has sales professionals located in Chicago, Las Vegas and Vero
Beach who serve clients in the pay telephone provider and hospitality service
markets. The Company also engages a limited number of brokers or non-employee
sales aggregators nationwide. Sales cycles are typically measured in months.
 
  An important component of the Company's sales and marketing efforts is its
customer support team. Once the sales staff has secured a customer contract,
Teltrust's customer support specialists work closely with the new customer to
coordinate operations set up and implement the appropriate technical interface
applications, such as switch interfaces and customized data communications
processes. In addition, the customer support staff works with the Company's
clients to establish quality standards and tailor Teltrust's services to the
individual needs of such customers. In addition, as customer support
specialists learn about new customers, they work with sales and marketing
personnel to attract these customers to other components of the Company's
suite of services.
 
  The Company's advertising and promotional activities include the production
of a variety of sales and marketing materials across all markets served. The
Company advertises in prominent trade publications, and produces white papers
and feature articles aimed at local and national publications. The Company has
a public relations program assisted by an outside public relations firm for
development of press materials and participates in major industry trade shows
in all of the Company's vertical markets.
 
OPERATIONS AND TECHNOLOGY
 
  The technology segments that support the Company's operations are (i)
switching and service agent centers, (ii) network technology, (iii)
information systems and (iv) remote systems and a network control center.
 
  SWITCHING AND SERVICE AGENT CENTERS. The Company utilizes Harris 2020
switches for both tandem and operator switching systems for its call
processing and calling card services. The Company utilizes the Harris
Protocall operator services systems for automated and live agent services. In
its calling card operations, the Company utilizes the Harris 2020 system as
the base switching system. The Harris 2020 system is modular and scalable in
design allowing for cost-effective systems deployment from 768 to 10,000
ports. The Harris 2020 system is fully certified for Class 4 (tandem), agent
services/ACD and Class 5 (local exchange) operation, is fully Signaling System
7 ("SS7") compliant and has full critical component redundancy for network
reliability. In addition to such designed redundancy, each site has been
configured with fully redundant and dual redundant SS7 links, battery back-up
and triple redundant common control links from all sites to the Salt Lake City
tandem and network operations center. All sites are also supported by
emergency power systems.
 
  Switching sites for its call processing services currently include the
principal tandem location in Salt Lake City, four additional switching sites
in the Salt Lake City area and remote switching sites in Atlanta, Miami, Los
 
                                      37
<PAGE>
 
Angeles and New York City. Switching sites for the Company's calling card
operations currently include Salt Lake City and two switches in Atlanta. The
Company currently plans to install several new switch sites in 1998 to
accommodate additional business under contract.
 
  The following chart depicts the Company's switch deployment as at March 31,

(1)  The Company expects to terminate its operations at the Gatty Center in
     November 1998. Termination of such operations will result in a station-
     capacity reduction of 269 stations. Such capacity loss is expected to be
     offset, however, by the planned opening of an additional Utah-based
     service agent center in the quarter ending September 30, 1998 that would
     provide approximately 125 additional stations. After giving effect to a
     net 144-station capacity loss, the Company's utilization of its station
     capacity on a pro forma basis at March 31, 1998 would be 50% of capacity
     rather than 42%. The Company believes, however, that its current capacity
     is adequate for its existing business and that it will have the ability
     to add additional station capacity when required in the future.
 
  The Company operates a proprietary Least Queue Routing system for its call
processing services to provide the network the ability to query the service
agent center command routing database prior to selecting a location to which
to route each call. This system allows the network to be updated every second
as to the availability of agents in each functional service center which
increases overall efficiency while adding a level of redundancy not otherwise
available.
 
                                      38

  NETWORK TECHNOLOGY. The Company has developed a communications and control
network between all remote locations and the Salt Lake City main tandem and
the Company's network operations control center. The Company's communications
and control network provides triple redundant high-speed data communication
between each site and the main tandem, all service agent centers, the
information systems center and the network operations center. Each independent
function within the network that requires command and control is not only
triple redundant but all circuits are also routed on diverse routes for
greater reliability.
 
  The network technology operation utilizes highly reliable communications
equipment such as Codex, Cisco routers, Cisco ATM and 100Mb wide area data
networks. The Company has also embarked on a program of developing an even
higher level of network reliability with the deployment of synchronous optical
network self-healing technology between all locations in the greater Salt Lake
City area.
 
  INFORMATION SYSTEMS. The Company's information systems operation is based on
client server technology. Network data is processed by the information systems
department into a base call record. The Company utilizes the base call record
to deliver all revenue, traffic, utilization, exception and agent activity
reports. Complete and comprehensive reporting packages have been developed
over the last seven years. Network technology provides dual redundant data
feeds from all sites to the information systems operations. Data feeds are
both real time and hourly. Dual real-time feeds are crosschecked to each other
and the dual hourly feeds are also checked to each other. Accuracy is further
maximized by cross checking the real-time feeds to the hourly feeds. Data
processing systems are all client server systems with redundant or triple
redundant mission critical components. Quality control processes are managed
by the Company's information systems support and quality control group within
the information systems department. The Company has taken aggressive steps to
ensure that its information systems are able to consistently handle and
process information using post-year 2000 date information.
 
  REMOTE SYSTEMS AND NETWORK CONTROL. The Company presently monitors and
manages all sites, including all Salt Lake City sites, remotely from the
technical operations center. The present remote systems and network control
operation allows the Company's technical and engineering staff to manage and
monitor all network elements and network support elements remotely. The
Company's technical operations center currently utilizes several surveillance
systems for monitoring and managing its remote sites including: a Boole and
Babbage "Command Post" system used to monitor the Harris switches and many of
the site support systems; a General Signal 7 View system used to monitor SS7
links at all sites; a Hewlett Packard HP Open View system used to monitor all
peripheral processors, billing, validation, and fraud control processors,
local area networks, wide area networks, routers, data communications gear and
all other SNMP compliant network and network support elements.
 
  FRAUD PREVENTION. The Company presently utilizes a three-tiered fraud
prevention system: the Company's internal controls, checks conducted by the
Company's "Hub" provider and safeguards implemented by credit card companies.
All of the Company's switches have on-site proprietary fraud-control systems
that are redundant and utilize the validation, verification and fraud control
processes of both its validation "Hub" provider and each of the RBOCs and
major commercial credit card companies. Prior to any call being placed on the
network, the billing number or card number is checked against Teltrust's
proprietary fraud system which analyzes factors such as high usage in a short
time period, long call durations, high-risk location information,
international calling patterns and several other factors. After call
information clears the Company's proprietary fraud control application, a
query is sent to the validation "Hub" provider which conducts a similar fraud-
control check based on activity from dozens of other carriers that utilize the
validation networks. After call information clears the Hub provider's
scrutiny, a query is launched to the applicable RBOC or credit card system for
final verification. The applicable RBOC or credit card company conducts
additional audits on a more global basis and then sends an appropriate
acceptance, warning or negative response to the Hub provider which in turn
forwards such information to the Company's system. Statistics are provided on
a real-time basis to the Company's fraud control department and the technical
operations center for additional decision making if necessary. Management
believes that its fraud prevention program has enabled its losses attributable
to fraud to be substantially less than the industry average.

  YEAR 2000 COMPLIANCE. In mid-1997, the Company embarked upon an in-depth Y2K
compliance project. Working with the major system and software manufacturers,
the Company believes that it has achieved substantial compliance on all
systems and software utilized in its operations. Presently, the Harris
switching systems and the Harris-provided automated operator service systems
are Y2K compliant. In addition, the Company's billing and validation systems,
information systems, database systems and network surveillance and control
center systems are presently Y2K compliant. At present, the fraud control
systems at each of the Company's sites are not yet Y2K compliant; however,
each of such systems is being upgraded, with a target compliance date of
September 1998.
 
  Y2K compliance "inter-operability" testing is currently underway or has been
completed with all major customers such as BSLD, BSPC and ASI. All bulletin
board data files have been brought up to Y2K compliance, and all of the
Company's customers have been notified of the compliance methodology and file
modifications. The Company intends to continue to notify all customers of
compliance issues and implementation.
 
SIGNIFICANT CUSTOMER CONTRACTS
 
  The Company has entered into a series of multi-service contracts with BSLD,
BSPC, ACI and ASI. For the year ended December 31, 1997, operating revenues
from Teltrust's three contracts with BSLD and BSPC accounted for 2.7%, 11.9%
and 1.6% of the Company's operating revenues, and operating revenues from
these contracts are expected to generate a higher percentage of total
operating revenues in the future. The Company expects to begin earning
operating revenues under its contracts with ASI and ACI during the quarter
ending June 30, 1998. The Company believes its contracts with ASI and ACI will
generate significant operating revenues in the future. An overview of the
principal terms of Teltrust's contracts with these customers is set forth
below. See "Risk Factors--Risk Related to Loss of Substantial Customer
Contract" and "--Significant Customer Relationships."
 
  BELLSOUTH AGREEMENTS.  In November 1996, the Company entered into a contract
with BSLD under which the Company provides call processing and national
directory assistance services to BSLD's markets, which currently include
wireless markets, wireline markets outside of the nine-state BellSouth region
and certain intraLATA markets within the nine-state BellSouth region. At this
time, BellSouth does not have the authority to provide interLATA long distance
service within the nine-state BellSouth region. When BellSouth obtains such
authority and commences providing such service, this contract provides that
Teltrust will supply call processing and national directory assistance
services to BSLD in such expanded markets. It is expected, however, that when
BellSouth obtains the aforementioned authority, BSLD will cease using the
Company for automated call processing services. The initial term of the
contract expires on January 2000, but the agreement is automatically renewed
quarterly unless one of the parties provides prior written notice of its
intention to terminate.
 
  In February 1997, the Company entered into a contract with BSPC to provide
call processing and national directory assistance services for calls
originating from BSPC's paystations. In addition, the Company serves as the
interLATA network carrier for services originating from certain BSPC
locations. In the event that BellSouth becomes able to provide interLATA long
distance service within the nine-state BellSouth region, the Company will
cease to provide interLATA long distance carrier services and will lose the
interLATA network carrier operating revenues generated by the provision of
these services. The initial term of the contract expires in February 2002, but
the agreement is automatically renewed quarterly unless one of the parties
provides prior written notice of its intention to terminate.
 
  In October 1997, the Company entered into an additional contract with BSLD
to provide call processing and national directory assistance services for
calls placed through the 1-800-BELLSOUTH(TM) access number. As the contract is
currently structured, the Company earns revenues directly from the end-users
of its services and remits certain commissions to BSLD for calls initiated
outside the nine-state BellSouth region. The Company also contributes to the
expenses of marketing the 1-800-BELLSOUTH(TM)name. In the event BellSouth
receives regulatory authority to provide interLATA long distance service in
any of the nine states in the BellSouth region prior to December 31, 1999, the
nature of the relationship will change substantially so that the Company will
 
                                      40
<PAGE>
 
begin paying commissions that it has not previously incurred. If BellSouth
secures such regulatory authority in all nine states, the Company will
recognize a wholesale operating revenue stream under the terms of the November
1996 contract with BSLD, and the Company will no longer recognize operating
revenues from end-users. As a result, there would be a substantial reduction
in operating revenues to the Company. The Company would continue, however, to
be a provider of outsourced services to BSLD to support its 1-800-
BELLSOUTH(TM) service. The initial term of the contract expires on December
31, 1999, but the agreement is automatically renewed on a monthly basis unless
otherwise agreed by the parties. See "Risk Factors--Risks Related to
Substantial Customer Contract" and "Risk Factors--Significant Customer
Relationships."
 
  AMERITECH AGREEMENTS. In February 1998, the Company entered into a contract
with ASI to be a provider of call processing services for calls placed through
the 1-800-AMERITECH(TM) access number. Teltrust provides the
telecommunications services sold under such name which originate from the
Ameritech region. The ASI contract is scheduled to terminate in March 2000 but
is renewable at ASI's option for additional twelve-month periods. ASI has the
right to terminate the agreement if a change in control of the Company occurs
so that it is controlled by any of certain specified telecommunications
companies or, after the initial term of the contract, without cause.
 
  In September 1997, Quest entered into a contract with ACI to provide
technology and a variety of services in connection with ACI's prepaid calling
card program. ACI purchases from Teltrust on a wholesale basis services such
as calling card activation and personal identification number implementation,
card printing and design, and three-way calling, voice mail and similar
services. The initial term of this contract is scheduled to expire in
September 2000, but the agreement is automatically renewed on an annual basis
unless one of the parties delivers notice of its intention to terminate. ACI
has the right to terminate the agreement if a change in control of the Company
occurs so that it is controlled by any of certain specified telecommunications
companies.
 
  Each of the BSLD, BSPC, ASI and ACI contracts requires payment of a
contractually-agreed upon amount in the event of early termination of such
contracts without cause. There can be no assurance, however, that any such
amount will sufficiently compensate the Company for the investment it has made
to support the canceled contract or that it will replace the revenues it will
lose as a result of the early termination. Consequently, the failure of the
Company to obtain renewal of any of the contracts with BSLD, BSPC, ASI or ACI,
or the termination of such contracts, could have a material adverse effect on
the Company's business, financial condition and results of operations. See
"Risk Factors--Significant Customer Relationships."
 
PERSONNEL AND TRAINING
 
  The Company believes a key component of its success is the quality of its
employees; therefore, the Company emphasizes a systematic approach to
recruiting, training and managing qualified personnel. The Company enjoys a
full-time training staff that customizes programs for all its service
applications. Typically, training for call completion and national directory
assistance is a four-week process that includes classroom training and closely
supervised call handling. Sales and marketing personnel also attend the
training sessions provided to the Company's service agents. The Company
provides regular refresher training, motivational training sessions and
training on how to address process changes, new services features and enhanced
system functions.
 
  As of February 28, 1998, the Company employed approximately 1,030 persons.
Of this total, approximately 714 persons worked full time and 316 persons
worked on a part-time basis. None of the Company's employees are members of a
labor union or are covered by a collective bargaining agreement. The Company
believes that its relations with its employees are good. The Company has
located its primary switching and service agent centers in Salt Lake City to
take advantage of the available high quality, dedicated, multilingual work
force. The Company believes that its relatively high proportion of full time
employees provides a stable work force and reduces the Company's recruiting
and training expenditures.
 
COMPETITION
 
  The various markets in which the Company competes are characterized by
rapidly changing market forces, technological advancements and increasing
competition from large IXC- or RBOC-affiliated companies and a
 
                                      41
<PAGE>
 
variety of small, independent companies. The Company expects competition to
increase in the future. The Company attempts to differentiate itself from its
competitors by offering an integrated suite of services primarily on a
wholesale basis to other telecommunications companies. Other providers
currently offer each of the individual services and certain combinations of
the services offered by the Company, but Teltrust is unaware of any single
competitor offering the full range of products offered by the Company.
 
  CALL COMPLETION SERVICES. In the call completion services market, the
Company's principal competitors include RBOCs and RBOC affiliates, IXCs and
IXC affiliates, independent LECs, such as SNET and Century Telephone, and
other independent companies offering various forms of call completion services
including Opticom, a division of One Call Communications.
 
  NATIONAL DIRECTORY ASSISTANCE SERVICES. In the national directory assistance
services market, the Company's principal competitors include RBOCs and RBOC
affiliates, IXCs and IXC affiliates and independent LECs. The Company also
faces competition in this market from independent companies offering various
forms of directory assistance services including Metro One Telecommunications,
Excell Agent Services, INFONXX and HebCom. Management believes that many of
these independent companies typically focus on narrow market segments, such as
the wireless market, rather than offer directory assistance services to the
broader telecommunications marketplace.
 
  THIRD-PARTY VERIFICATION SERVICES. In the third-party verification services
market, the Company's principal competitors include specialized companies such
as Verification Plus--Advanced Datacomm, Quick Response, Unibase Technologies
and Century Telecommunication. The Company also faces competition from smaller
companies that offer automated verification services including VoiceLog and
Unitel. Because federal and state third-party verification rules typically
mandate that carrier verification services be conducted by an "independent"
third-party, the Company does not anticipate that large RBOCs, IXCs, or other
telecommunication carriers will enter this business segment.
 
  CALLING CARD SERVICES. In the calling card services market, the Company's
principal competitors include RBOCs and RBOC affiliates, IXCs and IXC
affiliates and independent LECs. The Company also faces competition in this
market from independent companies including SmarTalk Teleservices and Premiere
Technologies.
 
  The Company believes that the principal competitive factors in the
aforementioned markets are service, quality, price, reputation, technological
innovation and experience. Historically, the Company has sought to distinguish
itself from competitors based on its independence in the marketplace, the
quality of its product, the development of enhanced features and its
experience derived from successfully establishing its call centers and
operations centers. The Company believes, however, that its future growth will
depend on its ability to maintain and improve the quality of its products, and
to develop and successfully introduce new connectivity features and content.
 
PROPERTIES
 
  The Company's corporate headquarters is located in approximately 33,000
square feet of office space in Salt Lake City under a lease expiring March 31,
2004. The lease may be renewed for two additional five-year terms. On December
31, 1997, the Company acquired a building with approximately 25,000 square
feet in Atlanta as part of its acquisition of Quest. The Company also leases
approximately 124,000 square feet of space for its various call centers and
network operations in and around Salt Lake City, Los Angeles, New York City,
Atlanta and Miami. The various leases expire on dates ranging from November
30, 1998, to July 8, 2007. Most leases have renewal options. Additional office
space and equipment rooms will be leased as additional network switches are
added and the Company's operations are expanded. The Company believes that its
insurance coverage on these properties is adequate and in compliance with the
related leases.

GOVERNMENT REGULATION
 
  FEDERAL REGULATION OF LONG DISTANCE AND CALL PROCESSING SERVICES. The
Company, as a provider of call processing and calling card services, is
subject to substantial federal regulation. Under the Telephone Operator
Consumer Services Improvement Act of 1990 and implementing rules promulgated
by the FCC thereunder, interstate call processing services providers are
required to file "informational" tariffs, in order to ensure that their
aggregator customers unblock access to other providers of call processing
services and to identify their services prior to the initiation of charges,
through both an audible "brand" and the posting of consumer information near
pay telephones and other aggregator telephones. In addition, long distance
companies are required to obtain authority under Section 214 of the
Communications Act of 1934 (as amended) prior to providing international
service and to file tariffs setting forth their international rates and
charges with the FCC.
 
  Providers of interstate long distance, operator services and calling card
services are considered nondominant interstate service providers by the FCC
and, as such, have for many years been subject to an FCC policy, known as
"forbearance," pursuant to which rates and charges for such services are not
reviewed or affirmatively regulated by the FCC and, except for the requirement
to file informational tariffs for call processing services, tariff filings
were optional. However, a Supreme Court decision in 1994 reinstated the
requirement that all carriers file tariffs for all interstate communications
services. Under the Telecommunications Act of 1996, the FCC has proposed
extending the forbearance doctrine by requiring mandatory detariffing of all
interstate, nondominant interexchange services. Under this proposal, which has
been stayed pending legal challenges, long distance services including
traditional 1+ long distance services, travel and calling card services and
prepaid calling card services and call processing services available to
presubscribed customers would be provided as a nontariff offerings. Call
processing services provided at aggregator locations, such as hotels,
hospitals, prisons, public and private pay telephones etc., would not be
detariffed.
 
  The FCC's forbearance doctrine continues its traditional policy favoring
competition in the marketplace as the principal means of ensuring just and
reasonable interstate rates for telephone end-users. It nonetheless requires
that long distance companies implement methods, other than tariffs, for
setting rates, terms and other conditions of their relationship with end-
users. The FCC suggests that a legal relationship, known as an "implied-in-
fact" contract, may be established when the caller provides billing or payment
information and completes use of the telecommunications service.
 
  Since 1992, the FCC has been considering proposals for adoption of a billed
party preference system for interstate 0 + operator-assisted calls. A billed
party preference system is an access plan pursuant to which 0+ calls from
aggregator locations, including call processing services and calls placed with
calling cards, would be routed to the carrier chosen by the billed party,
rather than the presubscribed provider of call processing services, thus
eliminating the need for the caller to input an access code to "dial around"
the presubscribed carrier.
 
  In June 1994, the FCC had proposed that a billed party preference system
should apply to all interstate operator assisted 0 + calls. This proposed
solution was widely criticized by various IXCs, RBOCs, LECS, call processing
services providers and others as excessively costly and not in the public
interest. Trade associations representing both pay telephone providers and
competitive long distance companies had submitted alternative proposals for
rate "ceilings" on interstate call processing services as an alternative to a
billed party preference system. These rate ceiling proposals, with
modification, were tentatively endorsed by the FCC in a proposal to establish
benchmarks for call processing services rates at the average charges of AT&T,
MCI and Sprint, the three largest providers of interstate call processing
services. The FCC, in a June 1996 Notice of Proposed Rulemaking, proposed to
require call processing services providers that charge rates above the
benchmark to disclose the applicable charges to consumers orally before
completing a call. Although the FCC did not formally withdraw its earlier
proposal for implementation of a billed party preference system, it noted the
cost and widespread opposition to the billed party preference plan and sought
comment on the efficacy of rate benchmarks as an alternative to a billed party
preference system.
 
 
                                      43
<PAGE>
 
  In May 1997, the FCC adopted changes to its system of interstate access
charges to make them compatible with the pro-competitive, deregulatory
framework established by the Telecommunications Act of 1996. The FCC's access
reform order adopts various reforms to the existing rate structure for
interstate access that are designed to move access charges, over time, to more
economically efficient levels and rate structures. The FCC's access reform
order also imposes the phase-in of replacing usage-based carrier common line
charges with a line-based flat fee to be assesssed upon all telecommunications
carriers beginning on January 1, 1998. In addition, the FCC's access order
requires LECs to reduce their access revenue requirements by reducing
interconnection access charges to telecommunications carriers.
 
  In January 1998, the FCC took action on the billed party preference issue.
In its order, the FCC addressed what it views as widespread consumer
dissatisfaction concerning high charges by many IXCs and call processing
services providers for calls from public phones and other aggregator locations
such as pay telephones, hospitals, hospitality locations and educational
institutions. Rather than implement its billed party preference system or any
of the other alternative proposed by participants in the telecommunications
industry, the FCC has ordered all call processing services providers and IXCs
providing call processing services to orally disclose to "away from home
callers" how to obtain the total cost of a 0 + interstate domestic call,
before the call is connected. The FCC required that such consumer disclosure
must be done without the consumer having to hang up or dial a separate
telephone number and must be accomplished by dialing no more than two keys.
The FCC mandated that the rate notification apply to all domestic 0+
interstate calls. While the Company is unable to predict whether this
regulation will have a material adverse effect on the Company, it is a far
more favorable proposal to the Company than the original billed party
preference system proposal and other alternatives considered by FCC.
 
  FEDERAL REGULATION OF PREPAID CALLING CARD SERVICES. As noted above, prepaid
calling card services are considered interstate services, subject to the FCC's
forbearance doctrine and mandatory detariffing. Currently, providers of these
services are required to file tariffs with the FCC disclosing the rates, terms
and conditions of their services. The FCC has proposed to abolish this tariff
requirement, but its order has been stayed pending court review.
 
  PAYPHONE COMPENSATION. The Telecommunications Act of 1996 mandated that the
FCC promulgate rules to establish a per call compensation plan to insure that
all pay telephone providers are fairly compensated for each completed
intrastate and interstate pay telephone initiated call, including non-coin
calls for which pay telephone providers had not heretofore received
compensation. The FCC has established a two year "default" compensation rate,
effective October 7, 1997, of $0.284 per pay telephone originated toll free or
access code call. At the end of the two year interim period, the per call pay
telephone-compensation rate will be the deregulated market-based local coin
rate less $0.066. This amount is payable by all IXCs and may be passed through
to non-facilities-based resellers. The revised FCC rules continue to be
subject to regulatory and legal challenges.
 
  While prepaid calling cards are one of the types of so-called "dial-around"
calling for which compensation to pay telephone service providers is due under
the Telecommunications Act of 1996, the FCC has not fully addressed the unique
technical and competitive impact of per-call pay telephone compensation on
prepaid card services. Comments submitted by the International Telecard
Association, a prepaid card trade group, urged the FCC to limit pay telephone
compensation to calls completed to the end-user (i.e., the called party),
rather than calls that only reach the calling card "platform" switch via an
"800" toll-free access number. In a November 1996 order, the FCC accepted the
International Telecard Association's position and, in addition, ruled that pay
telephone compensation is to be implemented on a "carrier pays" basis, without
deciding how, if they choose to do so, facilities-based carriers may recover
such charges from their reseller customers.
 
  STATE REGULATORY ISSUES. Long distance service, call processing services and
prepaid and calling card services are also regulated at the state level
through state PUCs. Such regulation typically includes certification and/or
registration requirements, authorizations for changes in corporate control,
filing and approval of tariffs for in-state calls and special consumer
protection rules applicable to call processing services and calling card
services. Certification can generally be conditioned, modified, canceled,
terminated or revoked by state regulatory
 
                                      44
<PAGE>
 
agencies for failure to comply with state law and/or the rules, regulations
and policies of the state regulatory authorities. Penalties, fines and other
sanctions, such as refund of monies collected from residents of a state, may
be imposed for violations such as overcharging, billing errors, or
noncompliance with certain requirements of intrastate services. In extreme
cases, PUCs have the authority to revoke a carrier's right to offer in-state
services within a state.
 
  In connection with the Company's provision of intrastate call processing
services and prepaid calling card services, the Company's Teltrust
Communications Services and Quest Telecommunications, Inc. subsidiaries must
maintain certificates of public convenience and necessity from state
regulatory authorities and are generally required to file tariffs with such
authorities.
 
  INTERNATIONAL REGULATORY ISSUES. International common carriers, such as the
Company and its regulated subsidiaries, are required to obtain authority under
Section 214 of the Communications Act of 1934 (as amended) and file a tariff
containing the rates, terms and conditions applicable to their services prior
to initiating their international value-added telecommunications services. The
Company has obtained all required authorizations from the FCC to use, on a
facilities and resale basis, various transmission media for the provision of
international switched services and international private line services.
 
LEGAL PROCEEDINGS
 
  The Company is not party to any legal proceedings which, individually or in
the aggregate, the Company expects to have a material adverse effect on its
financial condition or results of operations. The Company is, from time to
time, involved in regulatory proceedings before various PUCs, as well as
before the FCC.

(1) Amounts represent hypothetical gains that could be achieved for the
    respective options if exercised at the end of the option term. These gains
    are based upon assumed rates of share price appreciation set by the
    Securities and Exchange Commission of 5% and 10% compounded annually from
    the date the respective options were granted to their expiration date. The
    gains shown are net of the option exercise price but do not include
    deductions for taxes or other expenses associated with the exercise.
    Actual gains, if any, are dependent on the performance of the Common Stock
    and the date on which the option is exercised. There can be no assurance
    that the amounts reflected will be achieved.
(2) The exercise price equals the fair market value of the Common Stock on the
    date of grant as determined by the Company's Board of Directors.
(3) Such options vest in equal installments over the five-year period
    following the date of grant and terminate on the tenth anniversary of the
    date of grant.

STOCK OPTION PLANS
 
  1993 STOCK OPTION PLAN. The 1993 Stock Option Plan permits the grant of (i)
options to purchase shares of Common Stock intended to qualify as incentive
stock options under Section 422 of the Internal Revenue Code of 1986, as
amended, and (ii) options that do not so qualify. The 1993 Stock Option Plan
is designed and intended as a performance incentive for key employees,
including officers, of the Company to encourage such persons to acquire or
increase a proprietary interest in the success of the Company. The
Compensation Committee administers the 1993 Stock Option Plan and grants
options to eligible employees in its discretion
 
                                      50

3subject to certain limits in the 1993 Plan. As of April 1, 1998, options to
purchase 1,183,799 shares of Common Stock were outstanding and an additional
64,201 shares of Common Stock were available for issuance under the 1993 Stock
Option Plan.
 
  1998 STOCK OPTION PLAN. In April 1998, the Board of Directors adopted, and
the stockholders of the Company approved, the 1998 Stock Option Plan, which
authorizes the issuance of up to 800,000 shares of Common Stock. The 1998
Stock Option Plan permits the grant of (i) options to purchase shares of
Common Stock intended to qualify as incentive stock options under Section 422
of the Internal Revenue Code of 1986, as amended, (the "Code"), (ii) options
that do not so qualify, (iii) stock appreciation rights and (iv) restricted
and unrestricted stock awards.
 
  The 1998 Stock Option Plan is designed and intended as a performance
incentive for officers, directors, employees, consultants and other key
persons performing services for the Company to encourage such persons to
acquire or increase a proprietary interest in the success of the Company. The
1998 Stock Option Plan provides that it shall be administered by the
Compensation Committee appointed by the Board of Directors from time to time,
the majority of whom shall be non-employee directors. With respect to option
grants or other awards to executive officers of the Company under the 1998
Stock Option Plan, such grants and awards shall be subject to the approval of
the entire Board of Directors. The Compensation Committee determines the terms
of each individual stock option and stock award, subject to the terms of the
1998 Stock Option Plan, including the exercise price or purchase price of such
awards. The exercise price for incentive stock options must be equal to the
fair market value of the Common Stock on the date of grant. The exercise price
for non-qualified stock options and the purchase price for Common Stock awards
is determined at the discretion of the Compensation Committee. As of April 1,
1998, no options were outstanding under the 1998 Stock Option Plan and 800,000
shares of Common Stock were available for issuance under the 1998 Stock Option
Plan.

during each 182-day period during which such employee's noncompetition
agreement is in effect.

                         DESCRIPTION OF CAPITAL STOCK
 
AUTHORIZED AND OUTSTANDING CAPITAL STOCK
 
  Upon completion of the Offering, the authorized capital stock of the Company
will consist of    shares of Common Stock, of which 12,695,023 shares will be
issued and outstanding and 5,000,000 shares of undesignated preferred stock
issuable in one or more series by the Board of Directors ("Preferred Stock"),
of which no shares will be issued and outstanding.
 
  COMMON STOCK. The holders of Common Stock are entitled to one vote per share
on all matters to be voted on by stockholders and are entitled to receive such
dividends, if any, as may be declared from time to time by the Board of
Directors from funds legally available therefor. Any issuance of Preferred
Stock with a dividend preference over Common Stock could adversely affect the
dividend rights of holders of Common Stock. The holders of Common Stock are
not entitled to cumulative voting rights. Therefore, the holders of a majority
of the shares voted in the election of directors can elect all of the
directors then standing for election, subject to any voting rights of the
holders of any then outstanding Preferred Stock. The holders of Common Stock
have no preemptive or other subscription rights, and there are no conversion
rights or redemption or sinking fund provisions with respect to the Common
Stock. All outstanding shares of Common Stock, including the shares offered
hereby, are, or will be upon completion of the offering, fully paid and non-
assessable.
 
  The Company's By-laws, which will be effective upon completion of the
Offering, provide, subject to the rights of the holders of any Preferred Stock
then outstanding, that the number of directors shall be fixed by the
stockholders. The directors, other than those who may be elected by the
holders of any Preferred Stock, are divided into three classes, as nearly
equal in number as possible, with each class serving for a three-year term.
Subject to any rights of the holders of any Preferred Stock to elect
directors, and to remove any Director whom the holders of any Preferred Stock
had the right to elect, any Director of the Company may be removed from office
only with cause and by the affirmative vote of at least two-thirds of the
total votes which would be eligible to be cast by stockholders in the election
of such director.
 
  UNDESIGNATED PREFERRED STOCK. The Board of Directors of the Company is
authorized, without further action of the stockholders, to issue up to
5,000,000 shares of Preferred Stock in one or more series and to fix the
designations, powers, preferences and the relative, participating, optional or
other special rights of the shares of each series of preferred stock and any
qualifications, limitations and restrictions thereon as set forth in the
Company's Amended and Restated Certificate of Incorporation (the
"Certificate"). Any such Preferred Stock issued by the Company may rank prior
to the Common Stock as to dividend rights, liquidation preference or both, may
have full or limited voting rights and may be convertible into shares of
Common Stock.
 
  The issuance of Preferred Stock could have the effect of making it more
difficult for a third party to acquire a significant portion of the
outstanding Common Stock.
 
CERTAIN PROVISIONS OF CERTIFICATE OF INCORPORATION AND BY-LAWS
 
  A number of provisions of the Certificate and By-laws which will be
effective upon completion of the Offering concern matters of corporate
governance and the rights of stockholders. Certain of these provisions, as
well as the ability of the Board of Directors to issue shares of Preferred
Stock and to set the voting rights, preferences and other terms thereof, may
be deemed to have an anti-takeover effect and may discourage takeover attempts
not first approved by the Board of Directors, including takeovers which
stockholders may deem to be in their best interests. To the extent takeover
attempts are discouraged, temporary fluctuations in the market price of the
Common Stock, which may result from actual or rumored takeover attempts, may
be inhibited. These provisions, together with the classified Board of
Directors and the ability of the Board of Directors to issue Preferred Stock
without further stockholder action, also could delay or frustrate the removal
of incumbent directors or the assumption of control by stockholders, even if
such removal or assumption would be beneficial to stockholders of Company.
These provisions also could discourage or make more difficult a merger, tender
 
                                      55
<PAGE>
 
offer or proxy contest, even if favorable to the interests of stockholders,
and could depress the market price of the Common Stock. The Board of Directors
believes that these provisions are appropriate to protect the interests of the
Company and all of its stockholders. The Board of Directors has no present
plans to adopt any other measures or devices which may be deemed to have an
"anti-takeover effect."
 
  MEETINGS OF STOCKHOLDERS. The By-laws provide that a special meeting of
stockholders may be called only by the President or the Board of Directors
unless otherwise required by law. The By-laws provide that only those matters
set forth in the notice of a special meeting may be considered or acted upon
at such special meeting unless otherwise provided by law. In addition, the By-
laws set forth certain advance notice and informational requirements and time
limitations on any Director nomination or any new proposal which a stockholder
wishes to make at an annual meeting of stockholders.
 
  INDEMNIFICATION AND LIMITATION OF LIABILITY. The By-laws provide that
directors and officers of the Company shall be, and in the discretion of the
Board of Directors non-officer employees may be, indemnified by the Company to
the fullest extent authorized by Delaware law, as it now exists or may in the
future be amended, against all expenses and liabilities reasonably incurred in
connection with service for or on behalf of the Company. The By-laws also
provide that the right of directors and officers to indemnification shall be a
contract right and shall not be exclusive of any other right now possessed or
hereafter acquired under any by-law, agreement, vote of stockholders or
otherwise. The Certificate contains a provision permitted by Delaware law that
generally eliminates the personal liability of a director for monetary damages
arising from a breach of his or her fiduciary duty, including a breach
involving negligence or gross negligence in business combinations, unless such
director has breached his or her duty of loyalty, failed to act in good faith,
engaged in intentional misconduct or a knowing violation of law, paid a
dividend or approved a stock repurchase in violation of the Delaware General
Corporation Law or obtained an improper personal benefit. This provision does
not alter a director's liability under the federal securities laws and does
not affect the availability of equitable remedies, such as an injunction or
rescission, for breach of fiduciary duty. The Company has also entered into
indemnification agreements with each of its directors reflecting the foregoing
and requiring the advancement of expenses in proceedings involving the
directors in most circumstances.
 
  AMENDMENT OF THE CERTIFICATE. The Certificate provides that any amendment
thereof must first be approved by a majority of the Board of Directors and
(with certain exceptions) thereafter approved by a majority (or  % in the case
of any proposed amendment to the provisions of the Certificate relating to the
composition of the Board or amendments of the Certificate) of the total votes
eligible to be cast by holders of voting stock with respect to such amendment.
 
  AMENDMENT OF BY-LAWS. The Certificate provides that the By-laws may be
amended or repealed by the Board of Directors or by the stockholders. Such
action by the Board of Directors requires the affirmative vote of a majority
of the directors then in office. Such action by the stockholders requires the
affirmative vote of at least two-thirds of the total votes eligible to be cast
by holders of voting stock with respect to such amendment or repeal at an
annual meeting of stockholders or a special meeting called for such purpose
unless the Board of Directors recommends that the stockholders approve such
amendment or repeal at such meeting, in which case such amendment or repeal
shall only require the affirmative vote of a majority of the total votes
eligible to be cast by holders of voting stock with respect to such amendment
or repeal.
 
  ABILITY TO ADOPT SHAREHOLDER RIGHTS PLAN. The Board of Directors may in the
future resolve to issue shares of Preferred Stock or rights to acquire such
shares to implement a shareholder rights plan. A shareholder rights plan
typically creates voting or other impediments or under which shares are
distributed to a third-party investor, to a group of investors or shareholders
or to an employee stock ownership plan, to discourage persons seeking to gain
control of the Company by means of a merger, tender offer, proxy contest or
otherwise if such change in control is not in the best interest of the Company
and its stockholders. The Board of Directors has no
 
                                      56
<PAGE>
 
present intention of adopting a shareholder rights plan and is not aware of
any attempt to obtain control of the Company.
 
STATUTORY BUSINESS COMBINATION PROVISION
 
  The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law ("Section 203"). Section 203 provides, with certain
exceptions, that a Delaware corporation may not engage in any of a broad range
of business combinations with a person or affiliate, or associate of such
person, who is an "interested stockholder" for a period of three years from
the date that such person became an interested stockholder, unless: (i) the
transaction resulting in a person becoming an interested stockholder, or the
business combination, is approved by the board of directors of the corporation
before the person becomes an interested stockholder; (ii) the interested
stockholder acquired 85% or more of the outstanding voting stock of the
corporation in the same transaction that makes it an interested stockholder
(excluding shares owned by persons who are both officers and directors of the
corporation, and shares held by certain employee stock ownership plans); or
(iii) on or after the date the person becomes an interested stockholder, the
business combination is approved by the corporation's board of directors and
by the holders of at least 66 2/3% of the corporation's outstanding voting
stock at an annual or special meeting, excluding shares owned by the
interested stockholder. Under Section 203, an "interested stockholder" is
defined (with certain limited exceptions) as any person that is (i) the owner
of 15% or more of the outstanding voting stock of the subject corporation or
(ii) an affiliate or associate of the subject corporation that was the owner
of 15% or more of the outstanding voting stock of the subject corporation at
any time within the three-year period immediately prior to the date on which
it is sought to be determined whether such person is an interested
stockholder.
 
  A corporation may, at its option, exclude itself from the coverage of
Section 203 by amending its certificate of incorporation or by-laws by action
of its stockholders to exempt itself from coverage, provided that such by-law
or charter amendment shall not become effective until 12 months after the date
it is adopted. Neither the Certificate nor the By-laws contains any such
exclusion.
 
TRANSFER AGENT AND REGISTRAR
 
  The Company has selected      as the transfer agent and registrar for the
Common Stock.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of the Offering, the Company will have a total of 12,695,023
shares of Common Stock outstanding. Of the 12,695,023 outstanding shares, the
3,200,000 shares registered in the Offering will be freely tradeable without
restriction under the Securities Act (except that any shares purchased in the
Offering by "affiliates" of the Company may generally be resold only in
compliance with applicable provisions of Rule 144, as described below).
Beginning 90 days after the date of this Prospectus, an additional
shares maybe resold under Rule 144 without restriction under the Securities
Act subject to the volume and manner limitations set forth in Rule 144 and an
additional        shares may be resold under Rule 144 without such
restrictions (in each case, subject to the lock-up agreements described in
"Underwriting").
 
  In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned restricted securities
for at least one year (including the holding period of any prior owner except
an affiliate), including persons who may be deemed "affiliates" of the
Company, is entitled to sell within any three-month period a number of shares
that does not exceed the greater of one percent of the number of shares of
Common Stock then outstanding (approximately 126,950 shares upon completion of
the offering) or the average weekly trading volume of the Common Stock during
the four calendar weeks preceding the filing of a Form 144 with respect to
such sale. Sales under Rule 144 are also subject to certain manner of sale
provisions and notice requirements, and to the availability of current public
information about the Company. In addition, a
 
                                      57
<PAGE>
 
person who is not deemed to have been an affiliate of the Company at the time
during the 90 days preceding a sale, and who has beneficially owned the shares
proposed to be sold for at least two years (including the holding period of
any prior owner except an affiliate), would be entitled to sell such shares
under Rule 144(k) without regard to the requirements described above. Rule 144
also provides that affiliates who are selling shares that are not Restricted
Shares must nonetheless comply with the same restrictions applicable to
Restricted Shares with the exception of the holding period requirement.
 
  Rule 701 promulgated under the Securities Act provides that shares of Common
Stock acquired pursuant to the exercise of outstanding options or the grant of
Common Stock pursuant to written compensation plans or contracts prior to this
Offering may be resold by persons other than affiliates beginning 90 days
after the date of this Prospectus, subject only to the manner of sale
provisions of Rule 144, and by affiliates, beginning 90 days after the date of
this Prospectus, subject to all provisions of Rule 144 except its one-year
minimum holding period requirement.
 
  Certain stockholders of the Company (who in the aggregate will hold
restricted shares of Common Stock upon completion of the Offering) have
agreed, for a period of 180 days after the date of this Prospectus (the "Lock-
up Period"), pursuant to lock-up agreements and subject to certain exceptions,
not to (i) offer for sale, sell, pledge or otherwise dispose of any shares of
Common Stock or securities convertible into or exchangeable for Common Stock
or (ii) enter into any swap or other derivatives transaction that transfers to
another, in whole or in part, any of the economic benefits or risks of
ownership of such shares of Common Stock. Such stockholders have also agreed
not to cause the Company to effect the registration of such shares of Common
Stock or securities convertible into or exchangeable for Common Stock during
the Lock-up Period. In addition, the Company has agreed that for a period of
180 days after the date of this Prospectus, subject to certain exceptions, it
will not, without the prior written consent of Lehman Brothers Inc., offer,
sell or otherwise dispose of any shares of Common Stock except for shares of
Common Stock offered hereby.
 
  As of April 1, 1998, there were (i) 1,183,799 outstanding options to
purchase shares of Common Stock and 64,201 additional shares of Common Stock
reserved for issuance under the 1993 Stock Option Plan and (ii) no outstanding
options to purchase shares of Common Stock and 800,000 shares of Common Stock
reserved for issuance under the 1998 Stock Option Plan. The Company intends to
file a registration statement on Form S-8 under the Securities Act to register
all shares of Common Stock issuable pursuant to the 1993 Stock Option Plan and
the 1998 Stock Option Plan. The Company expects to file this registration
statement within 90 days following the date of this Prospectus, and such
registration statement will become effective upon filing. Shares covered by
this registration statement will thereupon be eligible for sale in the public
markets, subject to Rule 144 limitations applicable to affiliates and the
lock-up agreements described above.
 
  In connection with the investment of M/C III in the Company, the Company
entered into a registration rights agreement with M/C III and M/C Investors
(collectively, "the M/C Holders"). Upon Closing of the Offering, the M/C
Holders will hold 2,990,284 shares of Common Stock (the "M/C Shares"). At such
time as the Company is eligible to file a registration statement on Form S-3,
the Company shall, except during the 180-day period following the Closing of
the Offering and subject to certain other exceptions, upon request of the M/C
Holders use its best efforts to effect a registration of the number M/C Shares
requested to be so registered by the M/C Holders. During the term of such
registration rights agreement, the Company is obligated to effect an unlimited
number of registrations to the extent such registrations may be effected on
Form S-3. If the Company for itself or any of its security holders shall at
any time after the Offering determine to register under the Securities Act any
shares of its capital stock or other securities, subject to certain
exceptions, the Company is obligated to use its best efforts to cause such
number of M/C Shares as is requested by the M/C Holders to be included in such
registration statement to the extent permissible under the Securities Act.
 
  In connection with its acquisition of Quest, the Company entered into a
registration rights agreement with the former stockholders of Quest
(collectively, "the Quest Holders"). Upon Closing of the Offering, the Quest
Holders will hold 836,100 shares of Common Stock (the "Quest Shares"). At such
time as the Company is eligible to file a registration statement on Form S-3,
the Company shall, except during the 180-day period
 
                                      58
<PAGE>
 
following the Closing of the Offering and subject to certain other exceptions,
upon the request of holders of more than 50% of the Quest Shares, use its best
efforts to effect a registration of all or a portion of the Quest Shares. The
Company is not obligated to effect more than one such registration during any
12-month period. If the Company for itself or any of its security holders
shall at any time after the Offering determine to register under the
Securities Act any shares of its capital stock or other securities, subject to
certain exceptions, the Company is obligated to use its best efforts to cause
such number of Quest Shares as is requested by any Quest Holder to be included
in such registration statement to the extent permissible under the Securities
Act.
 
  Prior to this offering, there has been no public market for the Common Stock
and no prediction can be made of the effect, if any, that the sale or
availability for sale of shares of additional Common Stock will have on the
market price of the Common Stock. Nevertheless, sales of substantial amounts
of such shares in the public market, or the perception that such sales could
occur, could materially and adversely affect the market price of the Common
Stock and could impair the Company's future ability to raise capital through
an offering of its equity securities.

  The Underwriting Agreement provides that the obligations of the Underwriters
to pay for and accept delivery of the shares of Common Stock offered hereby
are subject to approval of certain legal matters by counsel and to certain
other conditions, as well as the requirement that, if any of the foregoing
shares of Common Stock are purchased by the Underwriters pursuant to the
Underwriting Agreement, all of the shares of Common Stock agreed to be
purchased by the Underwriters pursuant to the Underwriting Agreement (other
than those covered by the over-allotment option described below), must be so
purchased.
 
  The Company and the Selling Stockholders have granted to the Underwriters an
option to purchase up to an additional 480,000 shares of Common Stock at the
public offering price, less the aggregate underwriting discounts and
commissions shown on the cover page of the Prospectus, solely to cover over-
allotments, if any. The option may be exercised at any time up to 30 days
after the date of the Underwriting Agreement. To the extent that the
Underwriters exercise such an option, each of the Underwriters will be
committed, subject to certain conditions, to purchase a number of option
shares proportionate to such Underwriter's initial commitment as indicated in
the preceding table.
 
  Each of the Company and its executive officers and directors, and certain of
the Company's stockholders (including the Selling Stockholders) and option
holders, has agreed, for a period of 180 days after the date of this
Prospectus (the "Lock-up Period"), not to, directly or indirectly and subject
to certain exceptions, (i) offer for sale, sell, pledge, or otherwise dispose
of (or enter into any transaction or device that is designed to, or could be
expected to, result in the disposition by any person at any time in the future
of) any shares of Common Stock or securities convertible into or exchangeable
for Common Stock or (ii) enter into any swap or other derivatives transaction
that transfers to another, in whole or in part, any of the economic benefits
or risks of ownership of such shares of Common Stock. In addition, during the
Lock-up Period, the Company has agreed not to cause the registration of any
shares of such Common Stock or securities convertible into or exchangeable for
Common Stock.
 
  Prior to the Offering, there has been no public market for the shares of
Common Stock. There can be no assurance that an active trading market will
develop for shares of the Common Stock or as to the price at which shares of
the Common Stock may trade in the public market from time to time subsequent
to the Offering. The initial public offering price will be negotiated between
the Company and the Representatives. Among the factors to be considered in
determining the initial public offering price of the Common Stock, in addition
to prevailing market conditions, will be the Company's historical performance,
capital structure, estimates of the business potential and earnings prospects
of the Company and its industry in general, an overall assessment of the
Company, an assessment of the Company's management and the market price of
securities of companies engaged in businesses similar to that of the Company.
The initial price per share to the public set forth on the cover page of this
Prospectus should not, however, be considered an indication of the actual
value of the Common Stock. Such price is subject to change as a result of
market conditions and other factors.
 
  Application has been made to list the Common Stock on the Nasdaq National
Market under the symbol "TTST."

  Other than in the United States, no action has been taken in any
jurisdiction by the Company, the Selling Stockholders or the Underwriters that
would permit a public offering of the shares of Common Stock offered hereby in
any jurisdiction where action for that purpose is required. The shares of
Common Stock offered hereby may not be offered or sold, directly or
indirectly, nor may this Prospectus or any other offering material or
advertisements in connection with the offer and sale of any such shares of
Common Stock be distributed or published in any such jurisdiction, except
under circumstances that will result in compliance with the applicable rules
and regulations of such jurisdiction. Persons into whose possession this
Prospectus comes are advised to inform themselves about and to observe any
restrictions relating to the Offering and the distribution of this Prospectus.
This Prospectus does not constitute an offer to sell or a solicitation of an
offer to buy any shares of Common Stock offered hereby in any jurisdiction in
which such an offer or a solicitation is unlawful.
 
  If the Underwriters create a short position in the Common Stock in
connection with the Offering (i.e., if they sell more shares of Common Stock
than are set forth on the cover page of this Prospectus), the Representatives
may reduce that short position by purchasing Common Stock in the open market.
The Representatives may also elect to reduce any short position by exercising
all or part of the over-allotment option described herein.
 
  The Representatives may also impose a penalty bid on certain Underwriters
and selling group members. This means that if the Representatives purchase
shares of Common Stock in the open market to reduce the Underwriters' short
position or to stabilize the price of the Common Stock, they may reclaim the
amount of the selling concession from the Underwriters and selling group
members who sold those shares as part of the Offering.
 
  In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher
than it might be in the absence of such purchases. The imposition of a penalty
bid might also have an effect on the price of a security to the extent that it
were to discourage resales of the security by purchasers in an offering.
 
  Neither the Company nor any of 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 Representatives will engage in such transactions or
that such transactions, once commenced, will not be discontinued without
notice.
 
  Purchasers of the Common Stock offered hereby may be required to pay stamp
taxes and other charges in accordance with the laws and practices of the
country of purchase in addition to the offering price set forth on the cover
page hereof.
 
  The Representatives have informed the Company that they do not intend to
confirm sales of shares of Common Stock offered hereby to any accounts over
which they exercise discretionary authority.
 
                                 LEGAL MATTERS
 
  The validity of the shares of Common Stock offered hereby will be passed
upon for the Company by Goodwin, Procter & Hoar LLP, Boston, Massachusetts.
Certain legal matters related to the Offering will be passed upon for the
Underwriters by Cahill Gordon & Reindel (a partnership including a
professional corporation), New York, New York.

  CLEC (Competitive Local Exchange Carrier): A LEC that provides switched
local services in competition with the incumbent LEC (typically, an RBOC), as
an alternative for local transport of private line, special access and
interstate transport of switched access telecommunications services.
 
  Common Carrier: A government-regulated, private company that furnishes the
general public with telecommunications services and facilities (such as a
telephone or telegraph company).
 
  FCC: Federal Communications Commission.
 
  Hub: A collection center located centrally in an area where
telecommunications traffic can be aggregated at a central point for transport
and distribution.
 
  InterLATA Service: Telecommunications between a point located in a local
access and transport area and a point located outside such area.
 
  IntraLATA Service: Calls are those calls that originate and terminate within
the same LATA, but are outside the local calling area.
 
  IXC (Inter-Exchange Carriers): Usually referred to as long distance
providers. There are many facilities-based IXCs including AT&T, MCI, WorldCom
and Sprint, as well as numerous CLECs.
 
  LATA (Local Access Transport Area): The approximately 164 geographic areas
which define the regions in which each RBOC is authorized to provide service.
LATAs roughly reflect the population density of their respective states
(California has 11 LATAs while Wyoming has only one). The RBOCs are generally
prohibited from providing long distance service between LATAs in their
territory (i.e., interLATA services).
 
  LEC (Local Exchange Carrier): A company providing local telephone services,
including the RBOCs, GTE and more than 1,000 other independents. The term
includes incumbent LECs and CLECs.
 
  Local Exchange Services: Generally refers to all services provided by a LEC
or CLEC including local dial tone, the provision of telephone numbers, calling
within the local exchange area and long distance access services.
 
  Long Distance Carrier: A company providing interLATA or long distance
services between local exchanges on an intrastate or interstate basis. Long
distance carriers may also be long distance reseller companies. A long
distance carrier may offer services over its own or another carrier's
facilities. Major long distance carriers include AT&T, MCI, Sprint and
WorldCom and may also include resellers of long distance capacity.
 
  Network: Any system designed to provide one or more access paths for
communications between users at different geographic locations. Communications
networks may be designed for voice, text, data, facsimile image and/or video.
They may feature limited access (private networks) or open access (public
networks) and will employ whatever switching and transmission technologies are
appropriate.
 
  Paystation: A publicly accessible pay telephone.
 
  Platform: The Harris 2020 tandem switching system, Harris Protocall
automated operator system and, at some sites, a proprietary voice call
distribution system.
 
  PUC (Public Utility Commission): A state regulatory body, established in
most states, which regulates utilities, including telephone companies,
providing intrastate services.
 
 
                                      63
<PAGE>
 
  RBOC (Regional Bell Operating Company): One of the regional companies
created by the AT&T divestiture and their operating subsidiary companies. They
are Ameritech, Bell Atlantic, BellSouth, SBC Corporation (formerly
Southwestern Bell) and US WEST. The RBOCs have numerous unregulated
subsidiaries engaged in variety of communications-related and non-
communications businesses. The divestiture agreement barred RBOCs from
providing interLATA services within their service areas and from manufacturing
telecommunications equipment and certain other business activities, such as
providing long distance service, but provided mechanisms for review, waiver,
modification or removal of the prohibitions.
 
  Redundancy: The capability of telecommunications facility to use two
separate electronic devices to transmit a telecommunications signal so that if
one device malfunctions, the signal may continue without interruption.
 
  Reseller: A carrier that does not operate its own transmission facilities
(although it may own its own switches or other equipment) but obtains
communications services from another carrier for resale to the public for
profit.
 
  Slamming: The practice of unlawfully switching a customer's telephone
service provider without the consent of the affected consumer.
 
  SS7 (Signaling System 7): A sophisticated network signaling system that
utilizes out-of-band signaling where signaling information is sent over a
separate channel from the call itself. SS7 improves call processing set-up
times and frees circuits for voice, data and video transmissions.
 
  Switch: A mechanical or electronic device that opens or closes circuits or
selects the paths or circuits to be used for the transmission of information.
Switching is a process of interconnecting different circuits to create a
temporary transmission path between users. In operation, a switch may be a
sophisticated computer that accepts instructions from a caller in the form of
a telephone number. Like an address on an envelope, the numbers tell the
switch where to route the call. The switch opens or closes circuits or selects
the paths or circuits to be used for transmission of information. Switches
allow local telecommunications service providers to connect calls directly to
their destination while providing advanced features and recording connection
information for future billing.
 
  Telecommunications Act of 1996: Federal telecommunications legislation
passed in February 1996 which was to provide for a pro-competitive,
deregulatory national policy framework designed to accelerate rapidly private
sector deployment of advanced telecommunications and information technologies
and services in the United States by opening all telecommunications markets to
competition.
 
  Third-Party Verification: The process by which an independent third party
verifies a consumer's decision to change his or her selected IXC, CLEC or
other service provider.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Teltrust, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Teltrust,
Inc. (a Delaware corporation) and subsidiaries (collectively, the "Company")
as of December 31, 1996 and 1997, and the related consolidated statements of
operations, stockholders' equity (deficit) and cash flows for each of the
three years in the period ended December 31, 1997. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Teltrust,
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.

                        TELTRUST, INC. AND SUBSIDIARIES
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 NATURE OF OPERATIONS AND REORGANIZATION
 
  Teltrust, Inc. (formerly known as TTST Holdings, Inc.) was incorporated in
Delaware on April 8, 1998 to acquire all of the outstanding capital stock of
Teltrust Holdings, Inc., a Utah corporation (formerly known as Teltrust,
Inc.), through a corporate reorganization under the laws of Delaware and Utah.
This corporate reorganization was completed on April 22, 1998 (see Note 15).
The capital accounts presented in the accompanying consolidated balance sheets
reflect the authorized common and preferred stock of Teltrust, Inc., organized
on April 8, 1998. Teltrust and its subsidiaries (collectively referred to as
"the Company") provide a broad range of enhanced call processing and calling
card services to the domestic telecommunications industry. The Company
provides a broad range of enhanced call processing services, including call
completion, national directory assistance and third party verification
services, in addition to calling card services. Services are delivered through
the use of state-of-the-art technology, switch-based call processing platforms
and more than 1,000 employees. Telecommunications service providers contract
with the Company to provide enhanced call-processing services to their end
user business and consumer customers. The Company's customers include
interexchange carriers ("IXCs"), regional Bell operating companies ("RBOCs"),
other local exchange carriers ("LECs") and competitive local exchange carriers
("CLECs"), wireless providers, pay telephone and hospitality service
providers, calling card service providers, and international
telecommunications carriers. Customers access the Company's telecommunications
platforms and services through a multi-state leased line network served by
fourteen tandem and operator switches in eleven locations in Salt Lake City,
Atlanta, Los Angeles, Miami and New York City.
 
  During 1994, the Company launched new strategies and products designed to
position itself as a premier provider of enhanced call processing services to
take advantage of emerging markets in telecommunications. The continued
increase in telecommunications competition, fostered by the Telecommunications
Act of 1996 and subsequent entry of new providers created additional
opportunity for the Company to penetrate newly established markets with its
products. The Company further expanded its calling card services through the
acquisition of Quest Group International, Inc. and its affiliates
(collectively, "Quest") in December 1997 (see Note 3).
 
  The Company's sales have been, and the Company expects that its sales will
continue to be, somewhat seasonal, due to the nature of call traffic from
independent and LEC-owned pay telephones and the use of prepaid and other
calling cards. Traditional agent-assisted long distance services produce peak
revenues during the summer months, coincident with domestic travel and
vacation patterns. To a lesser degree, national directory assistance, prepaid
and other calling cards and third-party verification services are also
affected by seasonal demand fluctuations with demand peaking in the spring and
summer months.
 
 DISCONTINUED OPERATIONS
 
  Effective November 1, 1995, the Company entered into an agreement with
Cherokee Communications, Inc. for the sale of substantially all of the assets
of Teltrust Phones, Inc., a wholly-owned subsidiary of Teltrust, for
$3,664,889 in cash. Additionally, the Company is bound by a covenant not to
compete by operating or managing pay telephones for five years subsequent to
the effective date of the sale. A gain on the disposal of the subsidiary's
operations of $1,575,570 (before related income taxes of $587,688) has been
reflected in the accompanying 1995 consolidated statement of operations.
Revenue from discontinued operations was $3,275,781 for the period from
January 1, 1995 through October 31, 1995. Operating income and gain from
disposal of discontinued operations have been presented as separate captions
in the 1995 statement of operations.
 
NOTE 2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 PRINCIPLES OF CONSOLIDATION
 
  The accompanying consolidated financial statements include the accounts of
Teltrust and its wholly owned subsidiaries Teltrust Communication Services,
Inc. ("TCS"), Teltrust Phones, Inc. ("Phones", now inactive), Teltrust
Teleservices, Inc. ("Teleservices"), Quest Group International, Inc. and Quest
Real Estate, Inc. All significant intercompany transactions and accounts have
been eliminated in consolidation.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 CASH AND CASH EQUIVALENTS
 
  For purposes of the statements of cash flows, the Company considers all
highly liquid investments purchased with maturities of three months or less to
be cash equivalents.
 
 RESTRICTED CASH
 
  As of December 31, 1996, $6,900,000 of the Company's cash and cash
equivalents were restricted to repayment of an approximately $400,000
subordinated note payable to a stockholder, $2,500,000 to repurchase common
stock and $4,000,000 for capital expenditures. No such restriction existed as
of December 31, 1997.
 
 REVENUE RECOGNITION
 
  The Company's business is primarily transaction based, and accordingly,
revenues are recognized as services are performed.
 
CALL PROCESSING SERVICES
 
  Depending upon the nature of the relationship with its customer, the Company
may recognize revenue on a "wholesale basis" or a "retail basis". Wholesale
revenues consist of relationships where the Company provides a service to
another entity servicing the end-user. In a wholesale-type relationship, the
Company does not assume the credit risk from the end-user. Retail revenues
consist of relationships where the Company assumes ownership of the entire
call transaction and recognizes the gross call billing to the end-user as
revenue. In a retail-type relationship, the Company does assume the credit
risk related to the end-user. The following describes the nature of the
services and revenue earning process for each of the Company's call processing
services.
 
  .  Call Completion Services--These services consist of automated or live
     agent assisted calling card calling, collect calling and third-party
     billed calling. The Company earns revenues from its call completion
     services on a per-completed call, pre-call attempt or per-minute-of-use-
     basis. These services are performed on both a wholesale and retail
     basis.
 
  .  National Directory Assistance--These services consist of national
     directory assistance covering the 50 United States, the District of
     Columbia, Puerto Rico and the United States Virgin Islands. The Company
     generally earns revenues from this service on a wholesale, per-inquiry
     basis.
 
  .  Third-Party Verification Services--Third-party verification is an FCC
     requirement designed to protect consumers from unauthorized switching of
     an end-user's IXC, LEC or public utility provider without first
     obtaining the consent of the end-user. In providing this service, the
     Company acts as an independent third-party to verify an end-user's order
     to change its IXC, LEC or public utility provider. The Company generally
     earns fees from its third-party verification operations on a wholesale,
     per-call or hourly basis.
 
CALLING CARD SERVICES
 
  The Company's calling card services are provided through two applications:
wholesale applications and co-branded retail applications. In wholesale
service applications, customers purchase network and platform services from
the Company on a per-minute-of-use basis. Revenue is recognized as services
are provided. In co-branded retail service applications, customers purchase
calling cards from the Company at a discount from the retail value. The
Company receives cash upon the sale of prepaid calling cards, net of the
discount given to the co-branded services retail customer. The Company
recognizes revenue as the calling card is utilized by the end-user. Cash
received is recorded as unearned revenue in the accompanying consolidated
balance sheets.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 FAIR VALUE OF FINANCIAL INSTRUMENTS
 
  The book value of the Company's financial instruments approximates fair
value. The estimated fair values have been determined using appropriate market
information and valuation methodologies.
 
THIRD-PARTY BILLINGS RECEIVABLE
 
  The Company bills the majority of its accounts receivable under an agreement
with a third-party billing provider. This agreement allows the Company to
submit call detail records to the third-party billing provider, which in turn
forwards these records to LECs to be billed. The third-party billing provider
collects the funds from the LEC and then remits the funds, net of clearing
costs, to the Company. Because this collection process can take up to 90 days
to complete, the Company participates in an advance funding program offered by
the third-party billing provider whereby certain call records are purchased
for 80 percent of their value within five days of presentment. The remaining
20 percent of the value of the call records is remitted to the Company, net of
interest and clearing costs, as the third-party billing provider collects the
funds from the LECs. The allowance for clearing costs includes the Company's
estimate of uncollectible calls at December 31, 1996 and 1997. The Company's
customers are responsible for any amounts that ultimately are not collectible;
however, the Company is subject to the credit risks associated with collecting
these amounts from its customers. As of December 31, 1996 and 1997, the
Company has established reserves (estimated clearing costs) which management
believes are sufficient for potential charge backs.
 
  As a component of this agreement, the Company is charged interest on the 80
percent of the call record value which is advanced to the Company at the prime
lending rate as quoted in the Wall Street Journal (8.5 percent at December 31,
1997) plus two percent. The Company, in turn, charges its customers for
interest on these amounts at the same rate.
 
  The Financial Accounting Standards Board ("FASB") issued SFAS No. 125,
"Accounting for Transfers and Servicing of Financial Assets and
Extinguishments of Liabilities" in June 1996. This statement provides
accounting and reporting standards for, among other things, the transfer and
servicing of financial assets, such as factoring receivables with recourse.
The statement is effective for transfers and servicing of financial assets
occurring after December 31, 1996 and requires prospective application. In
December 1996, the FASB issued SFAS No. 127, "Deferral of the Effective Date
of Certain Provisions of SFAS No. 125." SFAS No. 127 amended the effective
date for certain provisions of SFAS No. 125 to December 31, 1997. The adoption
of these statements did not have a material impact on the financial position
or results of operations of the Company.
 
  As of December 31, 1996 and 1997, third-party billings receivables include
approximately $775,000 and $724,000, respectively, of gross billings for which
advance funding has not been received.
 
 PROPERTY AND EQUIPMENT
 
  Property and equipment are stated at cost. Depreciation and amortization are
computed using the straight-line method over the estimated useful lives of the
related assets. Upon sale or other disposition of property and equipment, the
cost and related accumulated depreciation or amortization is removed from the
accounts and any gain or loss is included in the determination of net income
or loss.
 
  Expenditures for maintenance and repairs are charged to expense as incurred.
Direct installation costs and major improvements are capitalized.

 INCOME TAXES
 
  The Company recognizes liabilities or assets for the deferred tax
consequences of all temporary differences between the tax bases of assets or
liabilities and their reported amounts in the financial statements. These
temporary differences will result in taxable or deductible amounts in future
years when the reported amounts of the assets or liabilities are recovered or
settled. The deferred tax assets are reviewed for recoverability and valuation
allowances are provided as necessary.
 
 RECENT ACCOUNTING PRONOUNCEMENT
 
  In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 131, "Disclosures About Segments
for an Enterprise and Related Information". The statement establishes new
standards for public companies to report information about operating segments,
products and services, geographic areas and major customers. This statement is
effective for periods beginning after December 15, 1997. The Company
anticipates it will have two reporting segments; namely, call processing
services and calling card services.
 
  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." SOP 98-5 requires costs of start-up activities and organization
costs to be expensed as incurred and is effective for financial statements for
fiscal years beginning after December 15, 1998. The Company currently expenses
such costs and therefore, the implementation of this pronouncement is not
expected to have any impact on the Company's financial position or results of
operations.
 
 PERVASIVENESS OF ESTIMATES
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions. The use of estimates and assumptions may affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts
of revenues and expenses during the reporting period. Actual results could
differ from those estimates.
 
  The Company manages its credit, theft and fraud risks through its internal
controls, monitoring and blocking systems. The Company also maintains reserves
which it deems adequate for such risks. However, past experience in estimating
and establishing reserves and the Company's historical losses may not
necessarily be accurate indications of the future. The Company believes that
its risk management and bad debt reserve practices are adequate; however the
actual losses resulting from unauthorized or returned transactions or thefts
of services could be different from those estimates.
 
 NET LOSS PER COMMON SHARE
 
  In accordance with SFAS No. 128, "Earnings per Share," basic net income per
common share ("Basic EPS") excludes the effects of all common stock
equivalents and convertible securities and is computed by

dividing net income by the weighted-average number of common shares
outstanding during the year. Diluted net income per common share ("Diluted
EPS") reflects the potential dilution that could occur if common stock
equivalents and convertible securities were exercised or converted into common
stock. The computation of Diluted EPS does not assume exercise or conversion
of securities that would have an anti-dilutive effect on net income (loss) per
common share. The Company has incurred net losses for all years presented and
therefore, all common stock equivalents were excluded from the calculation of
diluted loss per common share for the years ended December 31, 1995, 1996 and
1997 because they would have been anti-dilutive, thereby decreasing the net
loss per common share.
 
  At December 31, 1995, 1996 and 1997, there were outstanding options to
purchase 589,000, 873,648 and 1,183,799 shares, respectively, of common stock.
In accordance with SFAS No. 128, in determining the net loss attributable to
common stockholders, the Company has increased the net loss by undeclared
dividends on preferred stock of $131,507 and $1,200,000 for the years ended
December 31, 1996 and 1997, respectively. There were no undeclared preferred
stock dividends for the year ended December 31, 1995. The calculation of basic
and dilutive net loss per common share is as follows for 1995, 1996 and 1997:

 SIGNIFICANT CUSTOMERS
 
  Three contracts with two independent affiliates of one RBOC accounted for
approximately 2.7%, 11.9% and 1.6% of the Company's 1997 consolidated
revenues. There were no other customers that accounted for more than 10% of
the Company's consolidated revenues during 1995, 1996 and 1997. The Company's
five largest customers accounted for 20.4%, 27.3% and 39.7% of total operating
revenues for the years ended December 31, 1995, 1996 and 1997, respectively.
The Company expects that revenues attributable to a relatively small number of
customers will continue to represent a significant percentage of its total
revenues for the foreseeable future. The terms of the contracts with its most
significant customers have terms varying from one to three years. Although the
Company believes that it has good relationships with its customers, there can
be no assurance that the Company's customers, including its significant
customers, will continue to use the Company's services in amounts greater than
or similar to previous years, or at all. The loss or significant reduction of
revenues from its significant customers could have a material adverse effect
on the Company's results of operations and financial condition.
 
  At December 31, 1997, the customers with the four highest accounts
receivable balances totaled $6,857,289, or 55%, of gross accounts receivable.
At December 31, 1997, the outstanding accounts receivable balance from one
customer was $3,975,649, or 31%, of gross accounts receivable. If any one or a
group of these customers' receivable balances should be uncollectible, it
would have a material adverse effect on the Company's results of operations
and financial condition.

 ADVERTISING
 
  In accordance with Statement of Position 93-7, "Reporting on Advertising
Costs," costs for advertising are expensed as incurred within the fiscal year.
If it is determined that the advertising costs will provide a future economic
benefit, the costs are capitalized and amortized over the period of benefit,
not to exceed one year. For the years ended December 31, 1995, 1996 and 1997,
advertising expenses were $578,434, $1,051,480 and $1,025,838, respectively.
 
 ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS
 
  The Company accounts for impairment of long-lived assets in accordance with
SFAS No. 121, "Accounting for Impairment of Long-Lived Assets and for Long-
Lived Assets to be Disposed Of" ("SFAS No. 121"). SFAS No. 121 requires that
long-lived assets be reviewed for impairment when events or changes in
circumstances indicate that the book value of an asset may not be recoverable.
The Company evaluates, at each balance sheet date, whether events and
circumstances have occurred that indicate possible impairment. In accordance
with SFAS No. 121, the Company uses an estimate of future undiscounted net
cash flows of the related asset over the remaining life in measuring whether
assets are recoverable. As of December 31, 1997, the Company has determined
that none of its long-lived assets have been impaired.
 
NOTE 3 MERGER
 
  On December 31, 1997, the Company merged with Quest Group International,
Inc. and Quest Real Estate, Inc. (collectively, "Quest") in a stock-for-stock
transaction that resulted in Quest becoming a wholly owned subsidiary of
Teltrust, Inc. Under the terms of the agreement, Quest stockholders received
1.6516 shares of Teltrust common stock for each Quest share. Accordingly, the
Company issued 900,000 shares of common stock for all outstanding shares of
Quest common stock.
 
  The merger qualified as a tax-free reorganization and was accounted for as a
pooling-of-interests. Accordingly, the Company's financial statements have
been restated to include the accounts and operations of Quest for all periods
presented as though the two companies had always been a combined entity.
 
  Consolidated and separate results of Teltrust, Inc. and Quest during the
periods preceding the merger were as follows:

NOTE 4 REVOLVING LINE OF CREDIT
 
  In November 1997, the Company entered into a five-year Reducing Revolving
Credit Facility ("Credit Facility") with a bank in the amount of $15,000,000
(see Note 15). Up to the full amount of the Credit Facility may be borrowed,
repaid and reborrowed subject to quarterly reductions in the commitment amount
beginning on March 31, 1999, as follows:

     2002................................................   9.833     1,474,950
</TABLE>
 
  The Credit Facility's final maturity is September 30, 2002 and provides for
either Base Rate or LIBOR Rate advances at the Company's discretion. Base Rate
advances are at the bank's base rate plus 1.5% ("margin") and LIBOR Rate
advances are at the LIBOR rate plus 2.75% ("margin"). Beginning after March
31, 1998, the margin for the Credit Facility will be determined based upon the
ratio of total funded debt (the current outstanding balance of the Credit
Facility) to EBITDA (earnings before interest, taxes, depreciation and
amortization) (the "Ratio"). As the Ratio improves, the margin added to the
Base rate and the LIBOR rate declines. Among others, the financial covenants
include a requirement for a maximum ratio of 3.75 to 1.00 during 1998, 2.50 to
1.00 during 1999 and 1.50 to 1.00 thereafter.
 
  The Credit Facility is secured by a first priority perfected security
interest in all assets of the Company, including a pledge of all capital stock
of its subsidiaries. The Company pays maintenance fees of $25,000 per quarter
to continue the Credit Facility. Additionally, the Credit Facility contains
financial covenant requirements such as a maximum leverage ratio; minimum
interest, debt and fixed charge service coverage ratios; limitations on
additional debt; minimum EBITDA of $7,000,000 in 1998; and limits on capital
expenditures of $8,250,000 in 1998 and $5,000,000 in 1999 and subsequent
years.
 
  As of December 31, 1997, advances under the Credit Facility totaled
$12,100,000. These were LIBOR advances with an effective interest rate of 8.8
percent.

exercisable based upon a graduating exercise price and were exercised in
September 1997 at $1.00 per share. In connection with their issuance, the
Company valued these warrants at $50,000. The debt was originally recorded at
$450,000 and the principal balance was accreted through additional interest
expense up to the amount due when it was repaid.

  As a result of incurring taxable losses, the Company had no regular federal
income tax provision in 1995, 1996 and 1997. However, the Company is subject
to approximately $37,905, $6,577 and $5,218 of federal alternative minimum tax
and state income tax for the years ended December 31, 1995, 1996 and 1997,
respectively.
 
  For tax reporting purposes, the Company has consolidated net operating loss
carryforwards of approximately $17,347,000 at December 31, 1997 available to
offset future taxable income. Approximately $5,010,000 of the consolidated net
operating loss carryforwards can only be used by Quest, as those net operating
losses were generated by Quest prior to its merger with Teltrust. The Tax
Reform Act of 1986 contains provisions which limit net operating loss
carryforwards available based upon certain changes in ownership. In January
1997, changes in the ownership of Teltrust resulted in limitations on all pre-
existing net operating loss carryforwards of Teltrust. As a result, at
December 31, 1997, management estimates that $4,447,000 of the Company's net
operating loss carryforwards are limited to utilization of approximately
$1,692,000 per year. In December 1997, changes in the ownership of Quest
resulted in limitations on all pre-existing net operating loss carryforwards
of Quest. As a result, at December 31, 1997, management estimates that all of
the Quest net operating loss carryforwards are limited to utilization of
approximately $250,000 per year. If the annual limited amount is unutilized in
any particular year, it remains available on a cumulative basis through the
expiration date (15 years from the net operating loss inception date).

NOTE 8 COMMITMENTS AND CONTINGENCIES AND FINANCING NEEDS
 
 CLAIMS AND LEGAL ACTIONS
 
  The Company is involved in various claims and legal actions arising in the
ordinary course of business. In the opinion of management, after consultation
with legal counsel, the ultimate disposition of these matters will not have a
material adverse effect on the Company's financial position or results of
operations. However, due to the inherent uncertainty of litigation, there can
be no assurance that new developments or the resolution of any particular
claim or proceeding would not have an adverse effect on the Company's results
of operations for the period in which such new developments or resolution
occurred.
 
 EMPLOYMENT AGREEMENTS
 
  The Company has entered into noncompetition agreements with each of its
executive officers and other key employees which provide that, during the six-
month period following any such employee's termination of employment, the
employee shall refrain from engaging in any activities competitive with the
Company. The Company has the right to extend the initial six-month period for
up to five additional six-month periods. The Company, in turn, is obligated to
pay to such employee an amount equal to 100% of such employee's highest base
salary during the ninety-day period prior to his or her termination of
employment during each six-month period during which such employee's
noncompetition agreement is in effect.
 
 MINIMUM USAGE CHARGES
 
  The Company is obligated to pay approximately $3,000,000 during 1998 for
minimum usage (network) charges under agreements with certain providers of
network services. As of December 31, 1997, the Company had not entered into
any commitments beyond December 31, 1998 and believes that its existing
commitment will be used through the normal course of business in 1998 (See
Note 15).
 
 FINANCING NEEDS
 
  Primarily as a result of expenses associated with the expansion of its
business and certain infrastructure and capital equipment upgrades, the
Company has incurred significant net losses and negative cash flows from
operating activities during the years ended December 31, 1995, 1996 and 1997.
In addition, as of December 31, 1997, the Company has negative working capital
and a stockholders' deficit of $6,040,614 and $5,658,592, respectively. The
Company expects to incur significant expenditures in the future in connection
with the development and expansion of its call centers, network, services and
customer base. The ability of the Company to pursue its strategy and make
these expenditures is dependent, in part, upon the Company raising substantial
additional financing. There can be no assurance that the Company will achieve
or sustain profitability or generate positive cash flows in the future.
However, management believes that the availability under the Company's
revolving credit agreement and other available sources of financing will be
sufficient to fund the Company's working capital needs and required capital
expenditures through at least December 31, 1998.

NOTE 9 CAPITAL STOCK AND EQUITY TRANSACTIONS
 
 SERIES A CONVERTIBLE PREFERRED STOCK
 
  The Company's Series A Convertible Preferred Stock consists of 3,218,884
preferred shares and were issued on November 21, 1996 in exchange for
$15,000,000 of cash (before offering costs of $489,049). The holders of Series
A Convertible Preferred Stock, in preference to the holders of the Company's
common shares, are entitled to receive cumulative dividends at the rate of 8
percent per annum if, as and when declared by the Company's board of
directors. Undeclared or unpaid dividends are added to the liquidation
preference of the Series A Convertible Preferred Stock. In addition, the
holders of Series A Convertible Preferred Stock vote together with the shares
of the Company's common stock in the same manner as the Company's common
stock. Holders of Series A Convertible Preferred Stock are entitled, at their
option, to convert preferred shares (but not undeclared or unpaid dividends)
to common shares a conversion price of $4.66 per share. All of the Series A
Preferred Stock will convert to Common Stock in connection with the proposed
initial public offering discussed in Note 15.
 
  The affirmative vote of a majority of the then outstanding shares of Series
A Convertible Preferred Stock is required to affect any of the following
actions on behalf of the Company and its subsidiaries:
 
  .  Increasing the number of outstanding common or preferred shares.
 
  .  Increasing the Company's indebtedness beyond $3,000,000 in aggregate.
 
  .  Amending the Company's articles of incorporation and bylaws.
 
  .  Purchasing or selling of material assets.
 
  .  Merging, consolidating, liquidating, dissolving or winding up of
     business activities.
 
  .  Initiating new business activities outside the telecommunications
     sector.
 
  .  Executing any material contract or agreement which is outside of the
     ordinary course of business.
 
  .  Hiring or changing compensation, other than normal base salary
     adjustments to reflect cost-of-living increases, related to senior
     management personnel.
 
  The holders of Series A Convertible Preferred Stock have certain
registration rights which allow them to demand a registration statement to be
filed for which the Company would bear the cost of filing (except for
underwriters' discounts, commissions and legal counsel for selling
stockholders). Holders of Series A Convertible Preferred Stock may also
"piggyback' registration rights on registrations filed by the Company.
 
  The Company is required to keep available out of its authorized but unissued
shares of common stock such number of shares of common stock as are issuable
upon the conversion of all outstanding Series A Convertible Preferred Stock.
As of December 31, 1997, the Company has reserved 3,218,884 shares for such
purpose.
 
 COMMON STOCK WARRANTS
 
  During 1992, the Company issued warrants to purchase 2,000,520 shares of
common stock. The warrants were issued to stockholders in connection with the
issuance of subordinated notes payable from the Company. Each warrant was
exercisable at $0.167 per share, which was the estimated fair market value on
the date of grant. The Company valued these warrants at $100,000. The related
subordinated notes payable were recorded net of this amount and the principal
balance was accreted through additional interest expense to the amount due
when the debt was repaid. The warrants provided the stockholders with the
option to pay for the common stock with cash or by reducing the amount of
their subordinated notes by the equivalent amount. On March 31, 1997, all of
these warrants were exercised.

                        TELTRUST, INC. AND SUBSIDIARIES
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  During 1995, 1996 and 1997 the Company issued warrants to purchase 64,889,
69,227 and 45,968 shares of common stock, respectively. In connection with the
issuance of these warrants, the Company valued these warrants at $125,000,
$150,000 and $28,649, respectively. The warrants were issued to a venture
capital firm that entered into notes payable agreements with the Company (see
Note 5). The related notes payable were recorded net of this amount and the
principal balance was accreted through additional interest expense to the
amount due when the debt was repaid.
 
  During 1996, the Company issued warrants to purchase 400,000 and 100,000
shares of common stock. The warrants were issued to independent investors that
entered into subordinated revolving credit agreements with the Company (see
Note 5). In connection with their issuance, the Company valued these warrants
at $50,000. These warrants were exercised in 1997.
 
 COMMON STOCK OPTIONS
 
  The Company applies Accounting Principles Board Opinion No. 25 and related
interpretations in accounting for its stock option plan (as described below).
Accordingly, no compensation costs have been recognized for options granted
under its stock option plan to employees and directors. Had compensation costs
for the Company's stock-based compensation plan been determined based on the
fair value of the option at the grant dates for awards under the plan
consistent with statement of SFAS No. 123, "Accounting for Stock-Based
Compensation" ("SFAS No. 123"), the Company's net loss would have been
increased to the pro forma amounts indicated below:

     Pro forma........................ $     (0.49) $     (0.60) $      (2.53)
</TABLE>
 
  Because the SFAS No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995, and due to the nature and timing of
option grants, the resulting pro forma compensation costs may not be
indicative of future years.
 
  The fair value of each option grant has been estimated on the date of grant
using the Black-Scholes option pricing model with the following weighted
average assumptions used for grants in 1995, 1996 and 1997, in calculating
compensation costs:
 
  .  Risk-free interest rate of 6.10 percent, 6.95 percent and 6.30 percent
     for 1995, 1996 and 1997, respectively.
 
  .  Expected life of seven years for 1995, 1996 and 1997.
 
  .  No dividends and a volatility factor of zero.
 
  Effective September 27, 1994, the Company's stockholders approved the 1993
Employee Stock Option Plan (the "1993 Plan") by unanimous written consent. The
purpose of the 1993 Plan is to enable the Company to attract and retain
experienced and able officers, directors and other key employees. The 1993
Plan is administered by a committee, consisting of at least three members of
the board of directors (the "Committee"). Subject to the terms of the 1993
Plan, the Committee determines the persons who are to receive options, the
number of shares subject to each option and the terms and conditions of each
option. The Committee has the authority to construe and interpret any
provisions of the 1993 Plan or any options granted thereunder.

  In November 1996, an amendment to the 1993 Plan was adopted by the Company,
which increased the maximum number of shares of common stock that may be
issued pursuant to the 1993 Plan from 600,000 to 1,100,000. In December, an
amendment to the 1993 Plan was adopted by the Company, which increased the
maximum number of shares of common stock that may be issued pursuant to the
1993 Plan from 1,100,000 to 1,400,000.
 
  The 1993 Plan permits the granting of options that are intended to qualify
either as Incentive Stock Options ("ISO's") or Non-qualified Stock Options
("NQSO's"). The option exercise price for each ISO must be no less that 100
percent of the "fair market value' (as defined in the 1993 Plan) of a share of
common stock at the time such option is granted. Except in the case of a 10
percent or greater stockholder, in which case the exercise price must be no
less than 110 percent of fair market value. The Committee determines the
exercise price for each NQSO option at the time of grant. Both types of
options are exercisable for the period defined by the Committee on the date of
grant. However, no stock option will be exercisable before six months have
elapsed from the date it is granted and no incentive stock option shall be
exercisable after ten years from the date of grant.

NOTE 10 REGULATORY MATTERS
 
 FEDERAL REGULATION OF LONG DISTANCE AND CALL PROCESSING SERVICES
 
  The Company, as a provider of call processing and calling card services, is
subject to substantial federal regulation. Under the Telephone Operator
Consumer Services Improvement Act of 1990 and implementing rules promulgated
by the FCC thereunder, interstate call processing services providers are
required to file "informational' tariffs, in order to ensure that their
aggregator customers unblock access to other providers of call processing
services, and to identify their services prior to the initiation of charges,
through both an audible
 
                                     F-21
<PAGE>
 
                        TELTRUST, INC. AND SUBSIDIARIES
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
"brand' and the posting of consumer information near pay telephones and other
aggregator telephones. In addition, long distance companies are required to
obtain authority under Section 214 of the Communications Act of 1934 (as
amended) prior to providing international service and to file tariffs setting
forth their international rates and charges with the FCC.
 
  Providers of interstate long distance, operator services and calling card
services are considered nondominant interstate service providers by the FCC
and, as such, have for many years been subject to an FCC policy, known as
"forbearance," pursuant to which rates and charges for such services are not
reviewed or affirmatively regulated by the FCC and, except for the requirement
to file informational tariffs for call processing services, tariff filings
were optional. However, a Supreme Court decision in 1994 reinstated the
requirement that all carriers file tariffs for all interstate communications
services. Under the Telecommunications Act of 1996, the FCC has proposed
extending the forbearance doctrine by requiring mandatory detariffing of all
interstate, nondominant interexchange services. Under this proposal, which has
been stayed pending legal challenges, long distance services--including
traditional 1+ long distance services, travel and calling card services and
prepaid calling card services and call processing services available to
presubscribed customers--would be provided as a non-tariff offerings. Call
processing services provided at aggregator locations, such as hotels,
hospitals, prisons, public and private pay telephones, etc., would not be
detariffed.
 
  The FCC's forbearance doctrine continues its traditional policy favoring
competition in the marketplace as the principal means of ensuring just and
reasonable interstate rates for telephone end-users. It nonetheless requires
that long distance companies implement methods, other than tariffs, for
setting rates, terms and other conditions of their relationship with end-
users. The FCC suggests that a legal relationship, known as an "implied-in-
fact' contract, may be established when the caller provides billing or payment
information and completes use of the telecommunications service.
 
 BILLED PARTY PREFERENCE
 
  Since 1992, the FCC has been considering proposals for adoption of a billed
party preference system for interstate 0 + operator-assisted calls. A billed
party preference system is an access plan pursuant to which 0 + calls from
aggregator locations, including call processing services and calls placed with
calling cards, would be routed to the carrier chosen by the billed party,
rather than the presubscribed provider of call processing services, thus
eliminating the need for the caller to input an access code to "dial around'
the presubscribed carrier.
 
  In June 1994, the FCC had proposed that a billed party preference system
should apply to all interstate operator assisted 0 + calls. This proposal
conclusion was widely criticized by various IXCs, RBOCs, LECS, call processing
services providers and others as excessively costly and not in the public
interest. Trade associations representing both pay telephone providers and
competitive long distance companies had submitted alternative proposals for
rate "ceilings' on interstate call processing services as an alternative to a
billed party preference system. These rate ceiling proposals, with
modification, were tentatively endorsed by the FCC in a proposal to establish
benchmarks for call processing services rates at the average charges of AT&T,
MCI and Sprint, the three largest providers of interstate call processing
services. The FCC, in a June 1996 Notice of Proposed Rulemaking, proposed to
require call processing services providers that charge rates above the
benchmark to disclose the applicable charges to consumers orally before
completing a call. Although the FCC did not formally withdraw its earlier
proposal for implementation of a billed party preference system, it noted the
cost and widespread opposition to the billed party preference plan and sought
comment on the efficacy of rate benchmarks as an alternative to a billed party
preference system.
 
  In May 1997, the FCC adopted changes to its system of interstate access
charges to make them compatible with the pro-competitive, deregulatory
framework established by the Telecommunications Act of 1996. The FCC's access
reform order adopts various reforms to the existing rate structure for
interstate access that are
 
                                     F-22
<PAGE>
 
                        TELTRUST, INC. AND SUBSIDIARIES
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
designed to move access charges, over time, to more economically efficient
levels and rate structures. The FCC's access reform order also imposes the
phase-in of replacing usage-based carrier common line charges with a
line-based flat fee to be assesssed upon all telecommunications carriers
beginning on January 1, 1998. In addition, the FCC's access order requires
LECs to reduce their access revenue requirements by reducing interconnection
access charges to telecommunications carriers.
 
  In 1998, the FCC took action on the billed party preference issue. In its
order, the FCC addressed what it views as widespread consumer dissatisfaction
concerning high charges by many IXCs and call processing services providers
for calls from public phones and other aggregator locations such as pay
telephones, hospitals, hospitality locations and educational institutions.
Rather than implement its billed party preference system or any of the other
alternatives proposed by participants in the telecommunications industry, the
FCC has ordered all call processing services providers and IXCs providing call
processing services to orally disclose to "away from home callers' how to
obtain the total cost of a 0 + interstate domestic call, before the call is
connected. The FCC required that such consumer disclosure must be done without
the consumer having to dial a separate telephone number or hang up and dial a
separate telephone number and must be accomplished by dialing no more than two
keys. The FCC mandated that the rate notification apply to all domestic 0 +
interstate calls. While the Company is unable to predict whether this
regulation will have a material adverse effect on the Company, it is a far
more favorable proposal to the Company than the original billed party
preference system proposal and other alternatives considered by the Company.
 
 FEDERAL REGULATION OF PREPAID CALLING CARD SERVICES
 
  As noted above, prepaid calling card services are considered interstate
services, subject to the FCC's "forbearance' doctrine and mandatory
detariffing. Currently, providers of these services are required to file
tariffs with the FCC disclosing the rates, terms and condition of their
services. The FCC has proposed to abolish this tariff requirement, but its
order has been stayed pending current review.
 
 PAYPHONE COMPENSATION
 
  The Telecommunications Act of 1996 mandated that the FCC promulgate rules to
establish a per call compensation plan to insure that all pay telephone
providers are fairly compensated for each completed intrastate and interstate
pay telephone initiated call, including calls for which pay telephone
providers had not heretofore received compensation. The FCC has established a
two year "default' compensation rate, effective October 7, 1997, of $0.284 per
pay telephone originated toll free or access code call. At the end of the two
year interim period, the per call pay telephone-compensation rate will be the
deregulated market-based local coin rate less $0.066. This amount is payable
by all IXCs and may be passed through to nonfacilities based resellers. The
revised FCC rules continue to be subject to regulatory and legal challenges.
 
  While prepaid calling cards are one of the types of so-called "dial-around'
calling for which compensation to pay telephone service providers is due under
the Telecommunications Act of 1996, the FCC has not fully addressed the unique
technical and competitive impact of per-call pay telephone compensation on
prepaid card services. Comments submitted by the International Telecard
Association, a prepaid card trade group, urged the FCC to limit pay telephone
compensation to calls completed to the end-user (i.e., the called party),
rather than calls that only reach the calling card "platform' switch via an
"800' toll-free access number. In a November 1996 order, the FCC accepted the
International Telecard Association's position and, in addition, ruled that pay
telephone compensation is to be implemented on a "carrier pays' basis, without
deciding how, if they choose to do so, facilities-based carriers may recover
such charges from their reseller customers.
 
 STATE REGULATORY ISSUES
 
  Long distance, call processing services and prepaid and calling card
services are also regulated at the state level through state PUCs. Such
regulation typically includes certification and/or registration requirements,
 
                                     F-23
<PAGE>
 
                        TELTRUST, INC. AND SUBSIDIARIES
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
authorizations for changes in corporate control, filing and approval of
tariffs for in-state calls, and special consumer protection rules applicable
to call processing services and calling card services. Certification can
generally be conditioned, modified, canceled, terminated or revoked by state
regulatory agencies for failure to comply with state law and/or the rules,
regulations and policies of the state regulatory authorities. Penalties, fines
and other sanctions, such as refund of monies collected from residents of a
state, may be imposed for violations such as overcharging, billing errors, or
noncompliance with certain requirements of intrastate services. In extreme
cases, PUCs have the authority to revoke a carrier's right to offer in-state
services within a state.
 
  In connection with the Company's provision of intrastate call processing
services and calling and prepaid calling card services, the Company's
subsidiary, Teltrust Communication Services, Inc., must maintain certificates
of public convenience and necessity from state regulatory authorities and is
generally required to file tariffs with such authorities. In connection with
the Company's prepaid calling card services, the Company's subsidiary, Quest
International, Inc., must maintain certificates of public convenience and
necessity from state regulatory authorities and is generally required to file
tariffs with such authorities.
 
 INTERNATIONAL REGULATORY ISSUES
 
  International common carriers, such as the Company and its regulated
subsidiaries, are required to obtain authority under Section 214 of the
Communications Act of 1934 (as amended) and file a tariff containing the
rates, terms and conditions applicable to their services prior to initiating
their international value-added telecommunications services. The Company has
obtained all required authorizations from the FCC to use, on a facilities and
resale basis, various transmission media for the provision of international
switched services and international private line services.
 
NOTE 11 INVESTMENTS IN JOINT VENTURES
 
 FYI NATIONAL DIRECTORY ASSISTANCE
 
  In 1994, the Company entered into a joint venture general partnership
agreement with Metromail, Inc. to jointly market its directory assistance
service under the name of FYI National Directory Assistance ("NDA"). Each
party owned 50 percent of the joint venture. During 1995, the Company
contributed $25,000 as its initial investment in NDA. Metromail, Inc.'s
contribution to NDA was in the form of operator stations, software and the
directory data base. The Company accounted for this joint venture under the
equity method of accounting.
 
  On July 1, 1997, Teltrust and Metromail entered into a three-year Reseller
Agreement (the "Agreement") for the resale of national directory assistance
data from Metromail to Teltrust, thereby terminating the joint venture. The
Agreement includes minimum volume commitments aggregating 67,500,000 data
queries during the term of the Agreement in exchange for "most favored
customer' per data query pricing.
 
 DOT.ONE (FORMERLY TELTRUST DATA SERVICES, LLC D.B.A., TELTRUST.COM)
 
  In October 1994, the Company entered into a joint venture with Premier
Messaging Integrators, Inc. to jointly market its experience and expertise in
workgroup and messaging solutions to the greater Novell market place. The
joint venture was operated as a limited liability company under the laws of
the State of Utah. The Company's initial capital contribution was $100,000 for
its common ownership interest. The Company accounted for this joint venture
under the equity method of accounting.
 
  The Company advanced additional funds to dot.One in the form of loans in the
amount of $200,994, $574,016 and $581,576 during the years ended December 31,
1994, 1995 and 1996, respectively. These loans were generally interest bearing
and provided for repayment as cash (if any) became available from the profits
of dot.One.

                        TELTRUST, INC. AND SUBSIDIARIES
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Dot.One's operating agreement provided for the conversion of outstanding
loans, except for the original $100,000 start-up loan, into shares of capital
stock of dot.One. The exercise of this conversion option was at the sole
discretion of the Company. As of August 31, 1997, no outstanding debt of
dot.One had been converted to shares of capital stock.
 
  Effective August 31, 1997, the Company exchanged its common stock
investment, loans and accounts receivable for a preferred stock investment,
subordinated interest bearing loan (at 12 percent) and accounts receivable. As
of August 31, 1997, the Company commenced accounting for its investment in
dot.One under the cost method.
 
  During 1997, the Company determined that the realizability of its investment
($831,991 at December 31, 1997), the collectibility of its outstanding loans
($651,052 at December 31, 1997) and the collectibility of its outstanding
accounts receivable ($448,274 at December 31, 1997) were doubtful.
Accordingly, the Company established reserves during 1997 totaling $1,931,317
reflecting the write-down of its investment, subordinated loans and accounts
receivable related to dot.One. During the years ended December 31, 1995, 1996
and 1997, the Company billed dot.One approximately $775,000, $886,000 and
$774,000, respectively, for network services.
 
NOTE 12 RELATED-PARTY TRANSACTIONS
 
  During the years ended December 31, 1995, 1996 and 1997, the Company paid
approximately $60,000, $79,000 and $96,000, respectively, of insurance
premiums to an insurance company for which a former member of the board of
directors of the Company was an agent for the insurance company. The Company
believes these services were obtained at prices no less favorable than could
have been obtained from an independent party.
 
  At December 31, 1996 and 1997, the Company's notes receivable from related
parties on the consolidated balance sheet includes notes receivable from a
stockholder and officer of the Company. These notes bear interest at rates
ranging from 7 to 10 percent and mature at various times through December
1998.
 
  At December 31, 1996, the Company owed $251,434 to a related party. These
net payable amounts are the result of both receivable and payable transactions
arising from the day-to-day activities of the Company's NDA joint venture.
(see Note 11)
 
  During 1997, and in connection with the exercise of options to purchase
common stock, the Company loaned $145,200 to its CEO and President and $80,400
to its Vice Chairman. The notes receivable bear interest at prime (8.5 percent
at December 31, 1997) and are secured by the underlying common stock and other
personal assets of the officers. The notes receivable mature during 1999. The
notes receivable have been included in stockholder receivables, as an offset
to stockholders' equity, in the accompanying 1997 consolidated balance sheet.
 
  In December 1997, the Company paid to M/C III, L.L.C. a $75,000 fee for its
assistance in helping the Company to obtain its revolving line of credit. Two
members of the Company's board of directors are members of M/C III, L.L.C. M/C
III, L.L.C. is the general partner of Media/Communications Partners III,
Limited Partnership, a stockholder of the Company. The Company believes this
service was obtained at a price no less favorable than could have been
obtained from an independent party.
 
NOTE 13 EMPLOYEE BENEFIT PLAN
 
  During 1997, the Company established a contributory 401(k) savings and
profit sharing plan covering all eligible full-time employees. The Company's
contribution amount is determined at the discretion of the board of directors.
During the year ended December 31, 1997, the Company made no contributions to
the plan.

NOTE 15 SUBSEQUENT EVENTS
 
CORPORATE REORGANIZATION
 
  In connection with the corporate reorganization completed on April 22, 1998
(see Note 1), the Board of Directors authorized the assumption of the Teltrust
Holdings, Inc. 1993 Employee Stock Option Plan by Teltrust, Inc. All option
agreements were amended such that shares of Teltrust, Inc. common stock are to
be substituted for shares of common stock of Teltrust Holdings, Inc. to be
issued upon the proper exercise of the outstanding options. In addition, the
Board of Directors authorized the Company's registration rights agreements
with certain stockholders to be amended to reflect the reorganization. The
Board of Directors approved the Company becoming a guarantor of Teltrust
Holdings, Inc.'s obligations under the revolving line of credit. The common
stock of Teltrust Holdings, Inc. has been added as collateral to the Company's
revolving line of credit.
 
AMENDMENT OF REVOLVING LINE OF CREDIT
 
  The Company entered into an Amended and Restated Revolving Credit Note and
the First Amendment to the Credit Agreement (the "Amended Agreement")
effective April 10, 1998. In connection with the Amended

Agreement, the revolving line of credit was increased to $20,000,000. In
addition, the Amended Agreement requires the Company to deliver to the bank by
May 31, 1998 collateral assignments of policies insuring the lives of the
Company's CEO and President and Vice Chairman in the amount of not less than
$3,000,000 for the CEO and President and $2,000,000 for the Vice Chairman. The
Amended Agreement requires the Company to deliver, by December 31, 1998, a

OTHER MATTERS
 
  On April 9, 1998, the Board of Directors of the Company approved the
following:
 
 .  An initial public offering of the Company's common stock for up to
   $90,000,000 in aggregate gross proceeds to be allocated between the Company
   and certain selling stockholders.
 
 .  Adoption of the 1998 Teltrust, Inc. Stock Option and Grant Plan (the "1998
   Plan") with 800,000 shares of common stock reserved for issuance
   thereunder. The Compensation Committee of the Board of Directors will
   administer the 1998 Plan. The shares issuable under the 1998 Plan, as well
   as shares issuable under the 1993 Plan, are to be registered under the
   Securities Act of 1933 subsequent to the Company's initial public offering
   of common stock.
 
 .  Subject to the completion of the Company's initial public offering, the
   Board of Directors approved the appointment of the President of Billing
   Information Concepts, Inc. ("BIC") as a director of the Company. BIC has
   been the Company's third-party billing provider for approximately the last
   five years and is a major vendor to the Company. During the years ended
   December 31, 1995, 1996 and 1997, the Company paid BIC approximately
   $2,916,000, $2,379,000 and $2,245,000, respectively, for services provided
   to the Company.
 
  Effective March 27, 1998, the Company entered into an agreement to purchase
network services. The agreement requires the Company to purchase minimum
services of $500,000 per month over a two-year period for an aggregate minimum
commitment of $24,000,000. The Company believes that this commitment will be
fulfilled through the normal course of business during the commitment period.

</TABLE>
- ---------------------
(1) The amounts set forth above, except for the SEC, NASD and Nasdaq fees, are
    in each case estimated.
 
ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  In accordance with Section 145 of the General Corporation Law of the State
of Delaware, Article VII of the Company's Certificate, provides that no
Director of the Company shall be personally liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a Director,
except for liability (i) for any breach of the Director's duty of loyalty to
the Company or its stockholders, (ii) for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, (iii)
in respect of certain unlawful dividend payments or stock redemptions or
repurchases, or (iv) for any transaction from which the Director derived an
improper personal benefit. In addition, the Certificate provides that if the
Delaware General Corporation Law is amended to authorize the further
elimination or limitation of the liability of Directors, then the liability of
a Director of the Company shall be eliminated or limited to the fullest extent
permitted by the Delaware General Corporation Law, as so amended.
 
  Reference is made to Article V of the Amended and Restated By-laws of the
Company which provides for indemnification by the Company of its directors and
officers under certain circumstances against expenses (including attorneys'
fees, judgments, fines and amounts paid in settlement) actually and reasonably
incurred in connection with the defense or settlement of any threatened,
pending or completed legal proceeding in which any such person is involved by
reason of the fact that such person is or was a director or officer of the
Company if such person acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
Company, and, with respect to criminal actions or proceedings, if such person
had no reasonable cause to believe that his or her conduct was unlawful.
 
  Reference is made to the form of Underwriters Agreement (to be attached as
Exhibit 1 to this Registration Statement) which provides for indemnification
by the Underwriters of the directors and officers of the Company signing the
Registration Statement and certain controlling persons of the Company against
certain liabilities, including those arising under the Securities Act.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
  During the past three years, the Company has issued unregistered securities
to a limited number of persons, as described below. No underwriters or
underwriting discounts or commissions were involved. There was no public
offering in any such transaction, and the Company believes that each
transaction, unless otherwise noted,
 
                                     II-1
<PAGE>
 
was exempt from registration requirements of the Securities Act of 1933 as
amended (the "Securities Act"), by reason of Section 4(2) thereof, based on
the private nature of the transactions and the financial sophistication of the
purchasers, all of whom had access to complete information concerning the
Company and acquired the securities for investment and not with a view to the
distribution thereof.
 
  On April 14, 1995, Lyle O. Keys and Carmelo Catalano purchased an aggregate
of 1,063,000 shares of Common Stock at a purchase price of $2,126,000.
 
  On November 21, 1996, Media/Communications Partners III Limited Partnership
and M/C Investors L.L.C. purchased an aggregate of 3,218,884 shares of Series
A Preferred Stock at an aggregate purchase price of $14,510,951 (net of
issuance costs of $489,049).
 
  On March 31, 1997, Lyle O. Keys, Carmelo Catalano and Jerry E. Romney, Sr.
acquired 1,570,974, 405,000 and 24,546 shares of Common Stock, respectively,
upon the exercise of warrants for an aggregate purchase price of $333,426.
 
  On October 3, 1997, GFA Capital Corporation acquired 400,000 shares of
Common Stock upon the exercise of warrants for an exercise price of $400,000.
 
  On October 3, 1997, NuCom Company, LLC acquired 100,000 shares of Common
Stock upon the exercise of warrants for an exercise price of $100,000.
 
  On December 31, 1997, the Company issued 900,000 shares of Common Stock to
the stockholders of Quest International Group, Inc. and its affiliates
("Quest") in connection with the Company's acquisition of all of the
outstanding capital stock of Quest.
 
  Between April 15, 1995 and April 20, 1998, the Company issued options to
purchase 1,308,216 shares of Common Stock to employees of the Company pursuant
to the Company's 1993 Stock Option Plan and the Quest Stock Option Plan.
During such period, 190,017 shares of Common Stock were issued to option
holders upon exercise of options granted pursuant to the 1993 Stock Option
Plan and the Quest Stock Option Plan. The Company believes that the
transactions described in this paragraph are exempt from the registration
requirements of the Securities Act by reason of Rule 701 promulgated
thereunder because the issuance of the options described was pursuant to a
written compensatory benefit plan of the Company, a copy of which was given to
each participant in the plan, and the aggregate offering price did not exceed
the limit prescribed by Rule 701.

ITEM 17. UNDERTAKINGS
 
  The undersigned registrant hereby 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.
 
  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. In the event that a claim for
indemnification against such liabilities (other than payment by the registrant
of expenses incurred or paid by a director, officer or controlling person of
the registrant in the successful defense of any action, suit or proceeding)
 
                                     II-3
<PAGE>
 
is asserted by such director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.
 
  The undersigned registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
  We have audited in accordance with generally accepted auditing standards,
the consolidated financial statements of Teltrust, Inc. and subsidiaries
included in this registration statement and have issued our report thereon
dated March 6, 1998 (except with respect to the matters discussed in the first
paragraph of Note 1 and Note 15, as to which the date is April 22, 1998). Our
audit was made for the purpose of forming an opinion on the basic financial
statements taken as a whole. Schedule II is the responsibility of the
Company's management and is presented for purposes of complying with the
Securities and Exchange Commission's rules and is not part of the basic
financial statements. This Schedule has been subjected to the auditing
procedures applied in the audit of the basic consolidated financial statements
and, in our opinion, fairly states in all material respects the financial data

                                 CAPITAL STOCK
                                 -------------

     The total number of shares of capital stock which the Corporation shall
have authority to issue is twenty-five million (25,000,000) of which five
million (5,000,000) shall be shares of preferred stock, par value $.01 per
share, designated as Preferred Stock (hereinafter called "Preferred Stock"), and
twenty million (20,000,000) shall be shares of common stock, par value $.01 per
share, designated as Common Stock (hereinafter called "Common Stock").

     The powers, preferences, qualifications, restrictions, limitations and
relative rights of each class of shares (to the extent established hereby), and
the express grant of authority to the Board of Directors to amend this
Certificate of Incorporation to divide the Preferred Stock into series, to

the DGCL, as the same may be hereafter amended, are as follows:
<PAGE>
 
                              A.  PREFERRED STOCK
                                  ---------------

     1.   Number; Series.  The Preferred Stock shall be issued in one or more
          --------------                                                     
series.  The first series shall consist of 3,218,884 shares and is designated
"Series A Convertible Preferred Stock."  The remaining shares of Preferred Stock
may be issued from time to time in one or more series, with each such series to
have such designation, preferences, limitations and relative rights, as shall be
stated and expressed in an amendment to this Certificate of Incorporation
providing for the issue of such series.  The Board of Directors of the
Corporation is hereby expressly vested with authority to amend this Certificate
of Incorporation, without shareholder action or approval (other than as provided
in Section B.3 of this Article IV), to: (i) create one or more series of
Preferred Stock, fix the number of shares of each such series (within the total
number of authorized shares of Preferred Stock available for designation as a
part of such series), and designate and determine, in whole or part, the
preferences, limitations, and relative rights of each series of Preferred Stock;
(ii)  alter or revoke the preferences, limitations and relative rights granted
to or imposed upon any wholly unissued series of Preferred Stock; or (iii)
increase or decrease the number of shares constituting any series of Preferred
Stock (the number of shares of which was originally fixed by the Board of
Directors) either before or after the issuance of shares of the series, provided
that the number may not be decreased below the number of shares of such series
then outstanding, or increased above the total number of authorized shares of
the Preferred Stock available for designation as a part of such series.  The
authority of the Board of Directors with respect to each such series shall
include, but not be limited to, the determination or fixing of the following:

          (a)  The distinctive designation and number of shares comprising such
     series, which number may (except where otherwise provided by the Board of
     Directors in creating such series) be increased or decreased (but not below
     the number of shares then outstanding) from time to time by like action of
     the Board of Directors;

          (b)  The dividend rate of such series, the conditions and times upon
     which such dividends shall be payable, the relation which such dividends
     shall bear to the dividends payable on any other class or classes of stock
     or series thereof, or on the other series of the same class, and whether
     dividends shall be cumulative or noncumulative;

          (c)  The conditions upon which the shares of such series shall be
     subject to redemption by the Corporation and the times, prices and other
     terms and provisions upon which the shares of the series may be redeemed;

          (d)  Whether or not the shares of the series shall be subject to the
     operation of retirement or sinking fund provisions to be applied to the
     purchase or redemption of such shares and, if such retirement or sinking
     fund be established, the annual amount thereof and the terms and provisions
     relative to the operation thereof;

                                       2
<PAGE>
 
          (e)  Whether or not the shares of the series shall be convertible into
     or exchangeable for shares of any other class or classes, with or without
     par value, or of any other series of the same class and, if provision is
     made for conversion or exchange, the times, prices, rates, adjustments, and
     other terms and conditions of such conversion or exchange;

          (f)  Whether or not the shares of the series shall have voting rights,
     in addition to the voting rights provided by law, and, if so, the terms of
     such voting rights;

          (g)  The rights of the shares of the series in the event of voluntary
     or involuntary liquidation, dissolution, or upon distribution of assets of
     the Corporation;

          (h)  Any other powers, preferences and relative, participating,
     optional or other special rights, and qualifications, limitations or
     restrictions thereof, of the shares of such series, as the Board of
     Directors may deem advisable and as shall not be inconsistent with the
     provisions of this Certificate of Incorporation.

     2.   Preemptive Rights.  Except as may be provided in this Certificate of
          -----------------                                                   
Incorporation or an amendment hereto providing for the issue of any series of
Preferred Stock, or except as may be provided by contract, no holder of shares
of the Preferred Stock of the Corporation shall, as such holder, be entitled as
of right to subscribe for, purchase or receive any part of any new or additional
issue of stock of any class, whether now or hereafter authorized, or of bonds,
debentures or other securities convertible into or exchangeable for stock, but
all such additional shares of stock of any class, or bonds, debentures or other
securities convertible into or exchangeable for stock, may be issued and
disposed of by the Board of Directors on such terms and for such consideration,
so far as may be permitted by law, and to such persons, as the Board of
Directors in its absolute discretion may deem advisable.

B.   SERIES A CONVERTIBLE PREFERRED STOCK

     1.   Dividends.
          --------- 

     (a)  The holders of shares of Series A Convertible Preferred Stock, in
preference to the holders of the Junior Securities, shall be entitled to receive
if, as and when declared by the Board of Directors or upon the liquidation,
dissolution or winding up of the Corporation, and not otherwise, out of funds
legally available for such purpose, cumulative dividends as provided in this
Section 1.  Dividends on each share of Series A Convertible Preferred Stock
shall accrue at the rate of 8% per annum of the sum of (i) the Liquidation Value
and (ii) all accumulated and unpaid dividends thereon from the date of issuance.
Such dividends will be calculated and compounded annually on December 31 of each
year (each a "dividend date") in respect of the prior twelve month period (the
initial such calculation to be made at the same rate for the number of days
elapsed from the date of issue of the Series A Convertible Preferred Stock to
and including the 31st day of December, 1996).  Such dividends shall commence to
accrue on each share of Series A Convertible Preferred Stock from the date of
issuance thereof whether or not declared 

                                       3
<PAGE>
 
by the Board of Directors, and whether or not there are profits, surplus or
other funds of the Corporation legally available for the payment of dividends,
and shall continue to accrue thereon until the date the Liquidation Value of
such share (plus all accrued and unpaid dividends thereon) is paid or such share
is converted as set forth in Section 4. The amount of dividends accrued on the
Series A Convertible Preferred Stock pursuant to this Section in connection with
the sale, redemption or repurchase of any Series A Convertible Preferred Stock
between any two dividend dates shall equal the product of (a) the sum of (i) the
Liquidation Value plus (ii) all accumulated and unpaid dividends thereon as of
the immediately preceding dividend date, multiplied by (b) the product of (i) 8%
multiplied by (ii) a fraction, the numerator of which is the actual number of
days elapsed in the then current annual period and the denominator of which is
the total number of days comprising such annual period.

     (b)  If at any time the Corporation pays less than the total amount of
dividends then accrued with respect to the Series A Convertible Preferred Stock,
such payment shall be distributed ratably among the holders of Series A
Convertible Preferred Stock based upon the aggregate accrued but unpaid
dividends on the Series A Convertible Preferred Stock held by each holder.

     (c)  Without the consent of the holders of a majority of the issued and
outstanding Series A Convertible Preferred Stock, the Corporation shall not
declare, pay, or set apart for payment any dividends or make any other
distribution on any Junior Securities (other than stock dividends and
distributions in the nature of a stock split or the like), if there shall then
be outstanding any Series A Convertible Preferred Stock unless all dividends
theretofore accrued on the Series A Convertible Preferred Stock in accordance
with Section 1(a) shall have been declared by the Board of Directors and paid.
The holders of Series A Convertible Preferred Stock shall be entitled to
participate in all dividends and other distributions (other than stock dividends
and distributions in the nature of a stock split or the like and distributions
made upon the liquidation, dissolution and winding up of the Corporation's
affairs in addition to the amounts to which the holders of Series A Convertible
Preferred Stock are entitled in accordance with Section 2 hereof) that are
declared and paid on Common Stock in compliance with the provisions of this
Section 1(c) on the same basis as if all of the Series A Convertible Preferred
Stock had been converted into Common Stock in accordance with Section 4 hereof.

     (d)  Without the consent of the holders of a majority of the issued and
outstanding Series A Convertible Preferred Stock, the Corporation shall not
redeem any Junior Securities and will not permit any Subsidiary or other
affiliate to redeem, purchase or otherwise acquire for value, or set apart for
any sinking or other analogous fund for the redemption or purchase of, any
Junior Securities if there shall then be outstanding any Series A Convertible
Preferred Stock.

     2.   Liquidation Preference.
          ---------------------- 

     (a)  In the event of any liquidation, dissolution or winding up of the
affairs of the Corporation, either voluntarily or involuntarily, each holder of
Series A Convertible Preferred Stock shall be entitled, after provision for the
payment of the Corporation's debts and other 

                                       4
<PAGE>
 
liabilities, to be paid in cash, before any distribution is made on any Junior
Securities, the aggregate Liquidation Value of all shares of Series A
Convertible Preferred Stock held by such holder plus an amount equal to the sum
of all accrued and unpaid dividends thereon, whether or not declared to the date
of such payment. If, upon any such liquidation, dissolution or other winding up
of the affairs of the Corporation, the net assets of the Corporation
distributable among the holders of all outstanding Series A Convertible
Preferred Stock shall be insufficient to permit the payment in full to such
holders of the preferential amounts to which they are entitled under this
Certificate of Incorporation, then the entire net assets of the Corporation
remaining after provision for the payment of the Corporation's debts and other
liabilities shall be distributed among the holders of the Series A Convertible
Preferred Stock ratably in proportion to the full amounts to which they would
otherwise be respectively entitled. Holders of Series A Convertible Preferred
Stock shall not be entitled to any additional distribution in the event of any
liquidation, dissolution or winding up of the affairs of the Corporation in
excess of the preferential amount referred to above in this Section 2(a).

     (b)  The consolidation or merger of the Corporation into or with any other
entity or entities which results in the exchange of outstanding shares of the
Corporation for cash, securities or other consideration issued or paid or caused
to be issued or paid by any such entity or affiliate thereof (other than a
merger to reincorporate the Corporation in a different jurisdiction), and the
sale, lease, abandonment, transfer or other disposition of all or substantially
all its assets, shall be deemed to be a liquidation, dissolution or winding up
of the Corporation within the meaning of the provisions of this Section 2.

     3.   Voting.
          ------ 

     (a)  Except as otherwise required by law or as set forth herein and subject
to the rights of any class or series of Preferred Stock which may from time to
time come into existence hereafter, the shares of the Series A Convertible
Preferred Stock shall vote together with the shares of the Corporation's Common
Stock at any annual or special meeting of shareholders of the Corporation, or
may act by written consent in the same manner as the Corporation's Common Stock,
upon the following basis: Each holder of shares of Series A Convertible
Preferred Stock shall be entitled to such number of votes for the Series A
Convertible Preferred Stock held by it or him on the record date fixed for such
meeting, or on the effective date of such written consent, as shall be equal to
the whole number of shares of the Corporation's Common Stock into which its or
his shares of Series A Convertible Preferred Stock are convertible, in
accordance with the terms of Section 4 hereof, immediately after the close of
business on the record date fixed for such meeting or the effective date of such
written consent.

     (b)  The holders of shares of Series A Convertible Preferred Stock shall
also have the following voting rights:

          (i)  The affirmative vote of the holders of a majority of the then
     outstanding shares of Series A Convertible Preferred Stock, consenting or
     voting separately as a

                                       5
<PAGE>
 
     single class, as the case may be, in person or by proxy, at an annual or
     special meeting of stockholders called for the purpose, shall be necessary
     to do any of the following:

               (A)  authorize, or increase, or permit any Subsidiary to
          authorize or increase, the authorized number of shares of, or issue or
          permit any Subsidiary to issue any class or series of the
          Corporation's or any Subsidiary's capital stock or options, warrants
          or other rights to acquire any such capital stock other than shares
          issuable upon the exercise of Outstanding Options and shares issuable
          upon the exercise of Options and Convertible Securities that have been
          approved pursuant to the provisions of this Section 3(b)(i)(A);

               (B)  authorize the Corporation to, or permit any Subsidiary to,
          incur indebtedness for borrowed money, including, without limitation,
          indebtedness under capital leases or the like, if after giving effect
          to such incurrence the principal amount of Corporation's and the
          Subsidiaries' total indebtedness for borrowed money would exceed
          $3,000,000 in the aggregate;

               (C)  amend, repeal or change, directly or indirectly, any of the
          provisions of the Amended and Restated Certificate of Incorporation or
          the Amended and Restated Bylaws of the Corporation in any manner that
          would alter or change the powers, preferences or special rights of the
          shares of Series A Convertible Preferred Stock;

               (D)  authorize or effect, or permit any Subsidiary to authorize
          or effect, the sale of any material assets or business units of the
          Corporation or any Subsidiary;

               (E)  authorize or effect, or permit any Subsidiary to authorize
          or effect, the merger or consolidation of the Corporation or any
          Subsidiary with any other Person;

               (F)  authorize or effect, or permit any Subsidiary to authorize

     4.   Conversion Rights.
          ----------------- 

     (a)  Conversion Procedure.
          -------------------- 

          (i)  At any time and from time to time, any holder of Series A
     Convertible Preferred Stock shall have the right, at its option, to convert
     all or any portion of each share of Series A Convertible Preferred Stock
     (including any fraction of a share) held by such holder into such number of
     shares of fully paid and nonassessable Common Stock computed by dividing
     $4.66 by the Conversion Price in effect at the time of such conversion.

                                       7
<PAGE>
 
          (ii)  Each conversion of Series A Convertible Preferred Stock shall be
     deemed to have been effected as of the close of business on the date on
     which the certificate or certificates representing the Series A Convertible
     Preferred Stock to be converted have been surrendered at the principal
     office of the Corporation or at such other place as may be designated by
     the Corporation. At such time as any such conversion has been effected, the
     rights of the holder of such Series A Convertible Preferred Stock being
     converted as such holder shall cease (including the right to receive any
     accrued and unpaid dividends on such Series A Convertible Preferred Stock),
     and the Person or Persons in whose name or names any certificate or
     certificates for shares of Common Stock are to be issued upon such
     conversion shall be deemed to have become the holder or holders of record
     of the shares of Common Stock represented thereby.

          (iii) Notwithstanding any other provision hereof, if a conversion of
     Series A Convertible Preferred Stock is to be made in connection with a
     Public Offering, such conversion may, at the election of the holder of
     Series A Convertible Preferred Stock, be conditioned upon the consummation
     of the Public Offering, in which case such conversion shall not be deemed
     to be effective until the consummation of the Public Offering.

          (iv)  As soon as possible after a conversion has been effected (but in
     any event within five business days in the case of subparagraph (v) below),
     the Corporation shall deliver the following to the converting holder:

               (y)  a certificate or certificates representing, in the
          aggregate, the number of shares of Common Stock issuable by reason of
          such conversion, in the same name or names as the certificates
          representing the converted shares and in such denomination or
          denominations as the converting holder has specified and a check for
          cash with respect to any fractional interest in a share of Common
          Stock as provided in clause (viii) of this Section 4(a); and

               (z)  a certificate representing any shares which were represented
          by the certificate or certificates delivered to the Corporation in
          connection with such conversion but which were not converted.

          (v)  The issuance of certificates for shares of Common Stock
     conversion of Series A Convertible Preferred Stock shall be made without
     charge to the holders of such Series A Convertible Preferred Stock for any
     issuance tax in respect thereof or other cost incurred by the Corporation
     in connection with such conversion and the related issuance of shares of
     Common Stock. Upon conversion of any shares of Series A Convertible
     Preferred Stock, the Corporation shall take all such actions as are
     necessary in order to insure that the Common Stock usable with respect to
     such conversion shall be validly issued, fully paid and nonassessable.

                                       8
<PAGE>
 
          (vi)   The Corporation shall not close its books against the transfer
     of Series A Convertible Preferred Stock or of Common Stock issued or
     issuable upon conversion of Series A Convertible Preferred Stock in any
     manner which interferes with the timely conversion of Series A Convertible
     Preferred Stock. The Corporation shall assist and cooperate with any holder
     of shares of Series A Convertible Preferred Stock required to make any
     governmental filings or obtain any governmental approval prior to or in
     connection with any conversion of shares of Series A Convertible Preferred
     Stock hereunder (including, without limitation, making any filings required
     to be made by the Corporation).

          (vii)  The Corporation shall at all times reserve and keep available
     out of its authorized but unissued shares of Common Stock, solely for the
     purpose of issuance upon the conversion of the Series A Convertible
     Preferred Stock, such number of shares of Common Stock as are issuable upon
     the conversion of all outstanding Series A Convertible Preferred Stock. All
     shares of Common Stock which are so issuable shall, when issued, be duly
     and validly issued, fully paid and nonassessable and free from all taxes,
     liens and charges. The Corporation shall take all such actions as may be
     necessary to assure that all such shares of Common Stock may be so issued
     without violation of any applicable law or governmental regulation or any
     requirements of any domestic securities exchange upon which shares of
     Common Stock may be listed (except for official notice of issuance which
     shall be immediately delivered by the Corporation upon each such issuance).

          (viii) No fractional shares of Common Stock or script shall be issued
     upon conversion of shares of the Series A Convertible Preferred Stock. If
     more than one share of Series A Convertible Preferred Stock shall be
     surrendered for conversion at any one time by the same holder, the number
     of full shares of Common Stock issuable upon conversion thereof shall be
     computed on the basis of the aggregate number of shares of Series A
     Convertible Preferred Stock so surrendered. Instead of any fractional
     shares of Common Stock which would otherwise be issuable upon conversion of
     any shares of Series A Convertible Preferred Stock, the Corporation shall
     pay a cash adjustment in respect of such fractional interest equal to the
     fair market value of such fractional interest as determined by the
     Corporation's Board of Directors.

     (b)  Conversion Price.  The initial conversion price shall be $4.66, which
          ----------------                                                     
may be adjusted from time to time hereafter (the "Conversion Price") .  If and
whenever on or after the original date of issuance of the Series A Convertible
Preferred Stock the Corporation issues or sells, or in accordance with Section
4(c) is deemed to have issued or sold, any shares of its Common Stock or other
capital stock, options, warrants or other securities convertible into Common
Stock for a consideration per share less than the Conversion Price in effect
immediately prior to the time of such issue or sale, then forthwith upon such
issue or sale, the Conversion Price shall be reduced to an amount determined by
dividing (a) the sum of (1) the product derived by multiplying the Conversion
Price in effect immediately prior to such issue or sale times the number of
shares of Common Stock Deemed Outstanding immediately prior to such issue or
sale, plus (2) the consideration, if any, received (or deemed received pursuant
to Section 4(c) below) 

                                       9
<PAGE>
 
by the Corporation upon such issue or sale, by (b) the number of shares of
Common Stock Deemed Outstanding immediately after such issue or sale.

     (c)  Effect on Conversion Price of Certain Events.  For purposes of
          --------------------------------------------                  
determining the adjusted Conversion Price under this Section 4, the following
shall be applicable:

          (i)  Issuance of Rights or Options. If the Corporation in any manner
               -----------------------------
     grants any warrants or options or other rights to subscribe for or to
     purchase either (x) Common Stock or (y) any stock or other securities
     convertible into or exchangeable for Common Stock (such warrants, rights or
     options being herein called "Options" and such convertible or exchangeable
     stock or securities being herein called "Convertible Securities"), whether
     or not such Options or the right to convert or exchange any such
     Convertible Securities are immediately exercisable, and the price per share
     for which Common Stock is issuable upon the exercise of such Options or
     upon conversion or exchange of such Convertible Securities is less than the
     Conversion Price in effect immediately prior to the time of the granting of
     such Options, then the total maximum number of shares of Common Stock
     issuable upon the exercise of such Options or upon conversion or exchange
     of the total maximum amount of such Convertible Securities shall be deemed
     to be outstanding and to have been issued and sold by the Corporation at
     the time of the granting of such Options for such price per share. For
     purposes of this paragraph, the "price per share for which Common Stock is
     issuable" shall be determined by dividing (a) the total amount, if any,
     received or receivable by the Corporation as consideration for the granting
     of such Options, plus the minimum aggregate amount of additional
     consideration payable to the Corporation upon exercise of all such Options,
     plus in the case of such Options which relate to Convertible Securities,
     the minimum aggregate amount of additional consideration, if any, payable
     to the Corporation upon the issuance or sale of such Convertible Securities
     and the conversion or exchange thereof (such amount is the consideration
     "deemed received" for purposes of Section 4(b) above), by (b) the total
     maximum number of shares of Common Stock issuable upon the exercise of such
     Options or upon the conversion or exchange of all such Convertible
     Securities issuable upon the exercise of such Options. No further
     adjustment of the Conversion Price shall be made when Convertible
     Securities are actually issued upon the exercise of such Options or when
     Common Stock is actually issued upon the exercise of such Options or the
     conversion or exchange of such Convertible Securities.

          (ii) Issuance of Convertible Securities. If the Corporation in any
               ----------------------------------
     manner issues or sells any Convertible Securities, whether or not the
     rights to exchange or convert any such Convertible Securities are
     immediately exercisable, and the price per share for which Common Stock is
     issuable upon such conversion or exchange is less than the Conversion Price
     in effect immediately prior to the time of such issue or sale, then the
     maximum number of shares of Common Stock issuable upon conversion or
     exchange of such Convertible Securities shall be deemed to be outstanding
     and to have been issued and sold by the Corporation at the time of the
     issuance or sale of such Convertible Securities for such price per share.
     For the purposes of this paragraph, the "price per share for which

                                      10
<PAGE>
 
     Common Stock is issuable" shall be determined by dividing (a) the total
     amount received or receivable by the Corporation as consideration for the
     issue or sale of such Convertible Securities, plus the minimum aggregate
     amount of additional consideration, if any, payable to the Corporation upon
     the conversion or exchange thereof, by (b) the total maximum number of
     shares of Common Stock issuable upon the conversion or exchange of all such
     Convertible Securities. No further adjustment of the Conversion Price shall
     be made when Common Stock is actually issued upon the conversion or
     exchange of such Convertible Securities, and if any such issue or sale of
     such Convertible Securities is made upon exercise of any Options for which
     adjustments of the Conversion Price had been or are to be made pursuant to
     other provisions of this Section 4, no further adjustment of the Conversion
     Price shall be made by reason of such issue or sale.

          (iii)  Change in Option Price or Conversion Rate. If the purchase
                 -----------------------------------------
     price provided for in any Options, the additional consideration, if any,
     payable upon the conversion or exchange of any Convertible Securities, or
     the rate at which any Convertible Securities are convertible into or
     exchangeable for Common Stock change at any time, the Conversion Price in
     effect at the time of such change shall be readjusted to the Conversion
     Price which would have been in effect at such time had such Options or
     Convertible Securities then outstanding provided for such changed purchase
     price, additional consideration or changed conversion rate, as the case may
     be, at the time initially granted, issued or sold; but only if as a result
     of such adjustment the Conversion Price then in effect hereunder is thereby
     reduced; and on the termination date of any such Option or any such right
     to convert or exchange such Convertible Securities, the Conversion Price
     then in effect hereunder shall forthwith be increased to the Conversion
     Price which would have been in effect at the time of such termination had
     such Option or Convertible Securities, to the extent outstanding
     immediately prior to such termination, never been issued.

          (iv)   Exception for Outstanding Options. The adjustments provided for
                 ---------------------------------
     under this Section 4 for adjusting the Conversion Price shall not be
     applied with respect to the Outstanding Options or any shares of Common
     Stock issued upon the exercise of any of the Outstanding Options.

     (d)  Subdivision or Combination of Common Stock.  If the Corporation at any
          ------------------------------------------                            
time subdivides (by stock split, stock dividend, recapitalization or otherwise)
its outstanding shares of Common Stock into a greater number of shares, the
Conversion Price in effect immediately prior to such subdivision shall be
proportionately reduced, and, conversely, in case the outstanding shares of
Common Stock shall be combined (by reverse stock split or otherwise) into a
smaller number of shares, the Conversion Price in effect immediately prior to
such combination shall be proportionately increased.

     (e)  Certain Events.  If an event not specifically enumerated in this
          --------------                                                  
Section 4 occurs which has substantially the same economic effect on the Series
A Convertible Preferred Stock as those specifically enumerated shall occur, then
this Section 4 shall be construed liberally, mutatis mutandis, in order to give
                                             ----------------                  
the Series A Convertible Preferred Stock the benefit of the protections 

                                      11
<PAGE>
 
provided under this Section 4. The Corporation's Board of Directors shall make
an appropriate adjustment in the Conversion Price so as to protect the rights of
the holders of Series A Convertible Preferred Stock; provided that no such
                                                     --------
adjustment shall increase the Conversion Price as otherwise determined pursuant
to this Section 4 or decrease the number of shares of Common Stock issuable upon
conversion of each share of Series A Convertible Preferred Stock.

     (f)  Notices.
          ------- 

          (i)  Immediately upon any adjustment of the Conversion Price, the
     Corporation shall give written notice thereof to all holders of Series A
     Convertible Preferred Stock, setting forth in reasonable detail and
     certifying the calculation of such adjustment.

          (ii) The Corporation shall give written notice to all holders of
     Series A Convertible Preferred Stock at least twenty (20) days prior to the
     date on which the Corporation closes its books or takes a record (a) with
     respect to any dividend or distribution upon Common Stock, (b) with respect
     to any pro rata subscription offer to holders of Common Stock or (c) for
     determining rights to vote with respect to any dissolution or liquidation.

     (g)  Mandatory Conversion.  Each share of Series A Convertible Preferred
          --------------------                                               
Stock shall automatically be converted into fully paid and nonassessable shares
of Common Stock of the Corporation on the basis set forth in this Section 4
immediately upon the closing of a sale, pursuant to an effective registration
statement under the Securities Act of 1933, as amended, of shares of the
Corporation's Common Stock in a firmly underwritten registered initial public
offering in which the following two conditions shall be met:

          (i)  Aggregate gross proceeds to the Corporation (before underwriting
               discounts and commissions) of at least $25,000,000; and

          (ii) An offering price per share to the public equal to or greater
               than 300% of the then Liquidation Value (as adjusted for stock
               splits, stock dividends and combinations) of the Series A
               Convertible Preferred Stock.

Holders of shares of Series A Convertible Preferred Stock so converted may
deliver to the Corporation at its principal office (or such other office or
agency of the Corporation as the Corporation may designate by notice in writing
to such holders) during its usual business hours, the certificate or
certificates for the shares so converted.  As promptly as practicable
thereafter, the Corporation shall issue and deliver to such holder a certificate
or certificates for the number of whole shares of Common Stock to which such
holder is entitled, together with any cash dividends and payment in lieu of
fractional shares to which such holder may be entitled pursuant to this Section
4.  Until such time as a holder of shares of Series A Convertible Preferred
Stock shall surrender its certificate or certificates therefor as provided
above, such certificates shall be deemed to represent the shares of Common Stock
to which such holder shall be entitled upon the surrender thereof.

                                      12

     5.   Identical Rights.  Each share of the Series A Convertible Preferred
          ----------------                                                   
Stock shall have the same relative rights and preferences as, and shall be
identical in all respects with, all other shares of the Series A Convertible
Preferred Stock.

     6.   Certificates.  So long as any shares of the Series A Convertible

exercise is exempt from such registration requirements. The Eligible Employee
shall represent that unless and until the shares have been registered under the
Securities Act and applicable state securities laws: (1) the Eligible Employee
will be acquiring the shares upon exercise for investment purposes only and
without the intent of making any sale or disposition thereof, (2) the Eligible
Employee has been advised and understands that the shares underlying the Options
have not been registered for sale pursuant to federal and state securities laws
and are "restricted securities" under such laws, and (3) the Eligible Employee
acknowledges that the shares will be subject to stop transfer instructions and
bear a legend in substantially the following form in addition to any other
legend set forth in the Plan:

       THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
       THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER ANY STATE SECURITIES
       LAWS AND MAY NOT BE OFFERED, SOLD, OR TRANSFERRED IN THE ABSENCE OF
       REGISTRATION OR THE AVAILABILITY OF AN EXEMPTION FROM SUCH REGISTRATION.
       NO OFFER, SALE OR TRANSFER MAY TAKE PLACE WITHOUT PRIOR WRITTEN APPROVAL
       OF THE COMPANY BEING AFFIXED HERETO. IN THE ABSENCE OF AN EFFECTIVE
       REGISTRATION STATEMENT SUCH APPROVAL SHALL BE GRANTED ONLY IF THE COMPANY
       HAS RECEIVED AN OPINION OF SHAREHOLDER'S COUNSEL, AT SHAREHOLDER'S
       EXPENSE, SATISFACTORY TO THE COMPANY, TO THE EFFECT THAT SUCH SHARES MAY
       BE LAWFULLY TRANSFERRED PURSUANT TO AN EXEMPTION FROM REGISTRATION.

1.8        Acceptance of Notes to Finance Exercise

           The Corporation may, with the Committee's approval, accept one or
more notes from any Eligible Employee in connection with the exercise or receipt
of any outstanding Option, provided that any such note shall be subject to the
following terms and conditions:

           (a) The principal of the note shall not exceed the amount required to
be paid to the Corporation upon the exercise or receipt of one or more Options
under the Plan and the note shall be delivered directly to the Corporation in
consideration of such exercise or receipt

           (b) The initial term of the note shall be determined by the
Committee; provided that the term of the note, including extensions, shall not
exceed a period of five years.

           (c) The note shall provide for full recourse to the Employee
Participant and shall bear interest at a rate determined by the Committee but
not less than the applicable imputed interest rate specified by the Code.

           (d) if the employment of the Employee Participant terminates, the
unpaid principal balance of the note shall become due and payable on the 10th
business day after such termination; provided, however, that if a sale of such
shares would cause such Employee Participant to incur liability under Section
l6(b) of the Exchange Act, the unpaid balance shall become due and payable on
the 10th business day after the first day on which a sale of such shares could
have been made without incurring such liability assuming for these purposes that
there are no other transactions by the Employee Participant subsequent to such
termination.

                                       3
<PAGE>
 
           (e) If required by the Committee or by applicable law, the note shall
be secured by the shares financed thereby in compliance with applicable law.

           (f) The terms, repayment provisions, and collateral release
provisions of the note and the pledge securing the note shall conform with
applicable rules and regulations of the Federal Reserve Board as then in effect.

1.9        No Transferability

           Options may be exercised only by, and shares issuable pursuant to an
Option shall be issued only to (or registered only in the name of), the
Participant or, if the Participant has died, the Participant's Beneficiary or,
if the Participant has suffered a Disability, the Participant's Personal
Representative, if any, or if there is none, the Participant, or (to the extent
permitted by applicable law and Rule 16b-3) to a third party pursuant to such
conditions and procedures as the Committee may establish. Other than by will or
the laws of descent and distribution or pursuant to a QDRO or other exception to
transfer restrictions under Rule 16b-3 (except to the extent not permitted in
the case of an Incentive Stock Option), no right or benefit under this Plan or
any Option, shall be transferable by the Participant or shall be subject in any
manner to anticipation, alienation, sale, transfer, assignment, pledge,
encumbrance or charge (other than to the Corporation) and any such attempted
action shall be void. The Corporation shall disregard any attempt at transfer,
assignment or other alienation prohibited by the preceding sentences and shall
deliver such shares of Common Stock in accordance with the provisions of this
Plan. The designation of a Beneficiary hereunder shall not constitute a transfer
for these purposes.


                              II. EMPLOYEE OPTIONS

2.1        Grants

           One or more Options may be granted under this Article to any Eligible
Employee. Each Option granted may be either an Option intended to be an
Incentive Stock Option, or an Option not so intended, and such intent shall be
indicated in the applicable Option Agreement

2.2        Option Price

           (a) Pricing Limits. The purchase price per share of the Common Stock
covered by each Option shall be determined by the Committee at the time the
Option is granted, but in the case of Incentive Stock Options shall not be less
than 100% (110% in the case of a Participant who owns or is deemed to own under
Section 424(d) of the Code more than 10% of the total combined voting power of
all classes of stock of the Corporation) of the Fair Market Value of the Common
Stock on the Grant Date.

           (b) Payment Provisions. The purchase price of any shares purchased on
exercise of an Option granted under this Article shall be paid in full at the
time of each purchase in one or a combination of the following methods: (i) in
cash or by electronic fluids transfer; (ii) by check payable to the order of the
Corporation; (iii) if authorized by the Committee or specified in the applicable
Option Agreement, by a promissory note of the Participant consistent with the
requirements of Section 1.8; (iv) by notice and third party payment in such
manner as may be authorized by the Committee; or (v) by the delivery of shares
of Common Stock of the Corporation already owned by the Participant, provided,
however, that the Committee may in its absolute discretion limit the
Participant's ability to exercise an Option by delivering such shares. Shares of
Common Stock used to satisfy the exercise price of an Option shall be valued at
their Fair Market Value on the date of exercise.

2.3        Limitations on Grant and Terms of Incentive stock Options

           (a) $100,000 Limit. To the extent that the aggregate "fair market
value" of stock with respect to which incentive stock options first become
exercisable by a Participant in any calendar year exceeds $100,000, taking into
account both Common Stock subject to Incentive Stock Options under this Plan and
stock subject to incentive stock options under all other plans of the Company,
such options shall be treated as nonqualified stock options. For this purpose,
the "fair market value" of the stock subject to options shall be determined as
of the date the options were optioned. In reducing the number of options treated
as incentive stock options to meet the

                                       4
<PAGE>
 
$100,000 limit, the most recently granted options shall be reduced first. To the
extent a reduction of simultaneously granted options is necessary to meet the
$100,000 limit, the Committee may, in the manner and to the extent permitted by
law, designate which shares of Common Stock are to be treated as shares acquired
pursuant to the exercise of an Incentive Stock Option:

           (b) Option Period. Each Incentive Stock Option and all rights there
under shall expire no later than ten years after the Grant Date.

           (c) Other Code Limits. There shall be imposed in any Option Agreement
relating to Incentive Stock Options such terms and conditions as from time to
time are required in order that the Option be an "incentive stock option" as
that term is defined in Section 422 of the Code.

2.4        Limits on 10% Holders

           No Incentive Stock Option may be granted to any person who, at the
time the Option is granted, owns (or is deemed to own under Section 424(d) of
the Code) shares of outstanding Common Stock possessing more than 10% of the
total combined voting power of all classes of stock of the Corporation, unless
the exercise price of such Option is at least 110% of the Fair Market Value' of
the stock subject to the Option and such Option by its terms is not exercisable
after the expiration of five years from the date such Option is granted.

2.5        Option Repricing/Cancellation and Regrant/Waiver of Restrictions

           Subject to Section 1.4 and Section 3.6 herein and the specific
limitations on Options contained in this Plan, the Committee from time to time
may authorize, generally or in specific cases only, for the benefit of any
Eligible Employee, any adjustment in the exercise price, the number of shares
subject to or the term of, an Option granted under this Article by cancellation
of an outstanding Option and a subsequent regranting of an Option, by amendment,
by substitution of an outstanding Option, by waiver or by other legally valid
means. Such amendment or other action may result among other changes in an
exercise price which is higher or lower than the exercise or purchase price of
the original or prior Option, provide for a greater or lesser number of shares
subject to the Option, or provide for a longer or shorter vesting or exercise
period.

2.6        Company's Right to Repurchase Common stock Issued under the Plan

           (a) Repurchase Right. The Company shall have the right to repurchase
for cash all shares of Common Stock acquired by an Eligible Employee under the
Plan upon the Eligible Employee's termination of employment with the Company
(regardless of reason) for a purchase price per share equal to the price paid
for the shares by the Eligible Employee together with interest thereon at the
rate of ten percent (10%) per annum. This right to repurchase shall
automatically terminate and be of no further force or effect upon the earlier of
(i) thirty (30) days after the termination of employment of the Eligible
Employee, (ii) the registration of the Corporation's Common Stock under Section
12(g) of the Exchange Act, or (iii) the trading of the Corporation's Common
Stock on a recognized trading market such as NASDAQ or a national or regional
stock exchange.

           (b) Repurchase Legend. The face of certificates of Common Stock
issued to an Eligible Employee upon exercise of any Option shall bear a legend
in conspicuous capital letters in substantially the following form:

          THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
          RESTRICTIONS ON TRANSFER AND A REPURCHASE OPTION HELD BY THE ISSUER OR
          ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE ANY THE OPTION
          AGREEMENT. COPIES OF THESE DOCUMENTS ARE AVAILABLE AT THE PRINCIPAL
          OFFICE OF THE ISSUER IN SALT LAKE CITY, UTAH. SAID TRANSFER
          RESTRICTIONS AND REPURCHASE OPTION ARE BINDING UPON TRANSFEREES OF
          THESE SHARES.

                              III. OTHER PROVISIONS

3.1        Rights of Eligible Employees, Participants and Beneficiaries

           (a) Employment Status. Status as an Eligible Employee shall not be
construed as a commitment that any Option will be granted under this Plan to an
Eligible Employee or to Eligible Employees generally.

           (b) No Employment Contract. Nothing contained in this Plan (or in any
other documents related to this Plan or to any Option) shall confer upon any
Eligible Employee or other Participant any right to continue in the employ or
other service of the Company or constitute any contract or agreement of
employment or other service, nor shall interfere in any way with the right of
the Company to change such person's compensation or other benefits or to
terminate the employment of such person, with or without cause, but nothing
contained in this Plan or any document related hereto shall adversely affect any
independent contractual right of such person without his or her consent thereto.

           (c) Plan Not Funded. No Participant, Beneficiary or other person
shall have any right, title or interest in any fund or in any specific asset
(including shares of Common Stock, except as expressly otherwise provided) of
the Company by reason of any Option hereunder. Neither the provisions of this
Plan (or of any related documents), nor the creation or adoption of this Plan,
nor any action taken pursuant to the provisions of this Plan shall create, or be
construed to create, a trust of any kind or a fiduciary relationship between the
Company and any Participant, Beneficiary or other person.

3.2        Adjustments; Acceleration

           (a) Adjustments. If there shall occur any recapitalization, stock
split (including a stock split in the form of a stock dividend), reverse stock
split, reorganization, merger, combination, consolidation, split-up, spin-off
combination, repurchase, or exchange of Common Stock or other securities of the
Corporation, or there shall occur any other like corporate transaction or event
in respect of the Common Stock, then the Committee shall, in such manner and to
such extent (if any) as it deems appropriate and equitable (1) proportionately
adjust any or all of (a) the number and type of shares of Common Stock (or other
securities) which thereafter may be made the subject of Options (including the
specific maximum and numbers of shares set forth elsewhere in this Plan), (1))
the number, amount and type of shares of Common Stock (or other securities or
property) subject to any or all outstanding Options, (c) the grant, purchase, or
exercise price of any or all outstanding Options, (d) the securities issuable
upon exercise of any outstanding Options, or (2) in the case of an extraordinary
dividend or other distribution, merger, reorganization, consolidation,
combination, sale of assets, split-up, exchange, or spin-off, make provision for
a cash payment or for the substitution or exchange of any or all outstanding
Options or the securities deliverable to the holder of any or all outstanding
Options based upon the distribution or consideration payable to holders of the
Common Stock of the Corporation upon or in respect of such event; provided,
however, in each case, that with respect to Incentive Stock Options, no such
adjustment shall be made which would cause the Plan to violate Section 424(a) of
the Code or any successor provisions thereto.

           (b) Acceleration of Options Upon Change in Control. As to any
Eligible Employee Participant, unless prior to a Change in Control Event the
Committee determines that, upon its occurrence, there shall be no acceleration
of benefits under Options or determines that only certain or limited benefits
under Options shall be accelerated and the extent to which they shall be
accelerated, and/or establishes a different time in respect of such Event for
such acceleration, then upon the occurrence of a Change in Control Event each
Option shall become immediately exercisable. The Committee may override the
limitations on acceleration in this Section 3.2(b) by express provision in the
Option Agreement and may accord any Eligible Employee a right to refuse any
acceleration, whether pursuant to the Option Agreement or otherwise, in such
circumstances as the Committee may approve. Any acceleration of Options shall
comply with applicable regulatory requirements, including, without limitation,
Section 422 of the Code.

           (c) Possible Early Termination of Accelerated Options. If any Option
or other right to acquire Common Stock under this Plan has been fully
accelerated as permitted by Section 3.2(b) but is not exercised prior to (i) a
dissolution of the Corporation, or (ii) a reorganization event described in
Section 3.2(a) that the Corporation does not survive, or (iii), the consummation
of reorganization event described in Section 3.2(a) that results in a Change of
Control approved by the Board, and no provision has been made for the survival,
substitution, exchange or other settlement of such Option or right, such Option
or right shall thereupon terminate.

                                       6
<PAGE>
 
3.3        Effect of Termination of Employment

           The Committee shall establish in respect of each Option granted to an
Eligible Employee the effect of a termination of employment on the rights and
benefits thereunder and in so doing may make distinctions based upon the cause
of termination.

3.4        Compliance with Laws

           This Plan, the granting and vesting of Options under this Plan and
the issuance and delivery of shares of Common Stock under this Plan or under
Options granted hereunder are subject to compliance with all applicable federal
and state laws, rules and regulations (including, but not limited to, state and
federal securities laws and federal margin requirements) and to such approvals
by any listing, regulatory or governmental authority as may, in the opinion of
counsel for the Corporation, be necessary or advisable in connection therewith.
Any securities delivered under this Plan shall be subject to such restrictions,
and the person acquiring such securities shall, if requested by the Corporation,
provide such assurances and representations to the Corporation as the
Corporation may deem necessary or desirable to assure compliance with all
applicable legal requirements.

3.5        Tax Withholding

           (a) Cash or Shares. Upon any exercise or vesting of any Option or
upon the disposition of shares of Common Stock acquired pursuant to the exercise
of an Incentive Stock Option prior to satisfaction of the holding period
requirements of Section 422 of the Code, the Company shall have the right at its
option to (i) require the Participant (or Personal Representative or
Beneficiary, as the case may be) to pay or provide for payment of the amount of
any taxes which the Company may be required to withhold with respect to such
transaction or (ii) deduct from any amount payable in cash the amount of any
taxes which the Company may be required to withhold with respect to such cash
amount. In any case where a tax is required to be withheld in connection with
the delivery of shares of Common Stock under this Plan, the Committee may grant
(either at the time the Option is granted or thereafter) to the Participant the
right to elect, pursuant to such rules and subject to such conditions as the
Committee may establish, to have the Corporation reduce the number of shares to
be delivered by (or otherwise reacquire) the appropriate number of shares valued
at their then Fair Market Value, to satisfying such withholding obligation.

           (b) Tax Loans. The Committee may, in its discretion, authorize a loan
to an Eligible Employee in the amount of any taxes which the Company may be
required to withhold with respect to shares of Common Stock received (or
disposed of, as the case may be) pursuant to a transaction described in
subsection (a) above. Such a loan shall be for a term, at a rate of interest and
pursuant to such other terms and conditions as the Committee, under applicable
law, may establish and such loan need not comply with the provisions of Section
1.8.

3.6        Plan Amendment, Termination and Suspension

           (a) Board Authorization. The Board may, at any time, terminate or,
from time to time, amend, modify or suspend this Plan, in whole or in part. No
Options may be granted during any suspension of this Plan or after termination
of this Plan, but the Committee shall retain jurisdiction as to Options then
outstanding in accordance with the terms of this Plan.

           (b) Stockholder Approval. If any amendment would (i) materially
increase the benefits accruing to Participants under this Plan, (ii) materially
increase the aggregate number of securities that may be issued under this Plan,
or (iii) materially modify the requirements as to eligibility for participation
in this Plan, then to the extent then required by Rule 16b-3 to secure benefits
thereunder or to avoid liability under Section 16 of the Exchange Act (and Rules
thereunder) or required under Section 425 of the Code or any other applicable
law, or deemed necessary or advisable by the Board, such amendment shall be
subject to stockholder approval.

           (c) Amendments to Options. Without limiting any other express
authority of the Committee under but subject to the express limits of this Plan,
the Committee by agreement or resolution may waive conditions of or limitation
on Options to Eligible Employees that the Committee in the prior exercise of its
discretion has imposed, without the consent of a Participant, and may make other
changes to the terms and

                                       7
<PAGE>
 
conditions of Options that do not affect in any manner materially adverse to
the Employee Participant, his or her rights and benefits under an Option.

           (d) Limitations on Amendment to Plan and Options. No amendment,
suspension or termination of the Plan or change of or affecting any outstanding
Option shall, without written consent of the Participant, affect in any manner
materially adverse to the Participant any rights or benefits of the Participant
or obligations of the Corporation under any Option granted under this Plan prior
to the effective date of such change. Changes contemplated by Section 3.2 shall
not be deemed to constitute changes or amendments for purposes of this Section.

3.7        Privileges of Stock Ownership

           Except as otherwise expressly authorized by the Committee or this
Plan, a Participant shall not be entitled to any privilege of stock ownership as
to any shares of Common Stock not actually delivered to and held of record by
him or her. No adjustment will be made for dividends or other rights as a
stockholder for which a record date is prior to such date of delivery.

3.8        Effective Date of the Plan

           This Plan shall be effective when approved by the Teltrust, Inc.
shareholders.

3.9        Term of the Plan

           No Option shall be granted more than five years after the effective
date of this Plan (the "termination date"). Unless otherwise expressly provided
in this Plan or in an applicable Option Agreement, any Option theretofore
granted may extend beyond such date, and all authority of the Committee with
respect to Options hereunder shall continue during any suspension of this Plan
and in respect of outstanding Options on such termination date.

3.10       Governing Law; Construction; Severability

           (a) Choice of Law. This Plan, the Options, all documents evidencing
Options and all other related documents shall be governed by, and construed in
accordance with the laws of the State of Utah.

           (b) Severability. If any provision shall be held by a court of 
competent jurisdiction to be invalid and unenforceable, the remaining
provisions of this Plan shall continue in effect.

           (c) Plan Construction. It is the intent of the Corporation that this
Plan and Options hereunder satisfy and be interpreted in a manner that, in the
case of Participants who are or may be subject to Section 16 of the Exchange
Act, satisfy the applicable requirements of Rule 16b-3 so that such persons will
be entitled to the benefits of Rule 16b-3 or other exemptive rules under Section
16 of the Exchange Act and will not be subjected to avoidable liability
thereunder. If any provision of this Plan or of any Option would otherwise
frustrate or conflict with the intent expressed above, that provision to the
extent possible shall be interpreted and deemed amended so as to avoid such
conflict, but to the extent of any remaining irreconcilable conflict with such
intent as to such persons in the circumstances, such provision shall be deemed
void.

3.11       Captions

           Captions and headings are given to the sections and subsections of
this Plan solely as a convenience to facilitate reference. Such headings shall
not be deemed in any way material or relevant to the construction or
interpretation of the Plan or any provision thereof.

3.12       Effect of Change of Subsidiary Status

           For purposes of this Plan and any Option hereunder, if an entity
ceases to be a Subsidiary a termination of employment shall be deemed to have
occurred with respect to each employee of such Subsidiary who does not continue
as an employee of another entity within the Company. 

                                       8

3.13       Non-Exclusivity of Plan

           Nothing in this Plan shall limit or be deemed to limit the authority
of the Board or the Committee to grant options or authorize any other
compensation, with or without reference to the Common Stock, under any other
plan or authority.

reserved shall be overdue and unpaid, or any other sum payable by Tenant to
Landlord hereunder shall be overdue and unpaid, then Landlord may, at its
option (but Landlord shall not be required to), appropriate and apply any

and performed by Tenant, then Landlord, at its option, may appropriate and apply
the entire deposit, or so much thereof as may be necessary, to compensate
Landlord for loss or damage sustained or suffered by Landlord, due to such
breach on the part of Tenant. Should the entire deposit, or any portion thereof,
be appropriated and applied by Landlord for the payment of overdue lease
payments or other sums due and payable to Landlord, by Tenant hereunder, then
Tenant shall, upon the written demand of Landlord, forthwith remit to Landlord a
sufficient amount, in cash, to restore said security to the original sum

such demand shall constitute a breach of this Agreement. Should Tenant properly
comply with all of said terms, covenants and conditions, and properly comply
with all of the lease payments herein provided for, as they fall due, and all

Property, in the event that such interest be sold, and thereupon Landlord shall
be discharged from any further liability with respect to such deposit.

than $600,000 (before taxes), the security deposit reflected in subparagraph
5.04.A., above, shall be reduced to an amount equal to one (1) month's rent.
Thereafter and in the event Tenant's annualized income, based upon two (2)
consecutive fiscal quarters' performance, appears that Tenant's annualized
income (before taxes) is less than $600,000, the security deposit provided for
under this Section 5.04 shall be again increased to the amount specified in
subsection 5.04.A., above. Tenant shall deliver to Landlord quarterly financial
statements, accompanied by Tenant's certification thereof to the effect that
said financial statements are true, correct and complete, for each of Tenant's
fiscal quarters during the term hereof, beginning with the reduction of the
security deposit as provided in the first sentence of this subsection 5.04.E.

(3) diminish the general utility of the Premises.

additional space, in or on the Building or anywhere on the Land shown on Exhibit
"A" except in the actual space constituting the Premises. Tenant shall not, in

adequate notice to Tenant, also have the right to enter the Premises at all
times to inspect or to exhibit the same to prospective purchasers, mortgagees,
tenants, and lessees, and to make necessary repairs, additions, alterations or
improvements. During the six (6) months prior to expiration of this Lease or of

maintain property as required hereunder to the reasonable satisfaction of
Landlord as soon as reasonably possible after written demand, Landlord may make
such repairs without liability on its part to Tenant for any loss or damage that
may accrue to Tenant's business by reason thereof, and upon completion thereof,

against the Premises or any part thereof by reason of Tenant's acts or omissions
or because of a claim against Tenant, Tenant shall cause the same to be canceled
and discharged of record by bond or otherwise within thirty (30) days after
notice by Landlord.

                           ASSIGNMENT AND SUBLETTING
                           -------------------------

     13.01  No Assignment or Subletting by Tenant. Tenant may not assign or in
            -------------------------------------                             
any manner transfer this Lease or any interest, nor sublet nor re-let the
Premises or any part or parts, nor permit occupancy by anyone with, through or
under it, without the prior written consent of Landlord, which consent shall not
be unreasonably withheld. Consent by Landlord to one or more assignments or to
one or more subletting or re-lettings shall not operate as a waiver of
Landlord's right to refuse its consent to any subsequent assignment or
subletting or re-letting, nor release Tenant from any of its obligations nor be
construed as a waiver of any of the Landlord's rights or remedies hereunder. Any
assignment or subletting which in the Landlord's reasonable discretion shall
limit or reduce the price of space or hinder in any way the ability to lease
other space in the Building shall be adequate cause to refuse consent to the
assignment or subletting. Such prohibition against assigning or subletting shall
include any assignment or subletting by operation of law, any corporate
restructuring or reorganization. Any transfer of this Lease from the Tenant by
merger, consolidation, transfer of assets, or liquidation of this Lease from the
Tenant by merger, consolidation, transfer of assets, or liquidation shall
constitute an assignment for purposes of this Lease. In the event that Tenant
hereunder is a corporation, the transfer, assignment, or hypothecation of any
stock or interest in such corporation, in the aggregate in excess of forty-nine
percent (49%) shall be deemed an assignment within the meaning of this Section.
It is contemplated that Landlord will consent to an assignment by Tenant to
wholly owned or controlled subsidiaries or affiliates. Any assignment will also
be subject to approval of Landlord's lenders, if and when required. It is
contemplated that transfers of
<PAGE>
 
                                      16

ownership of stock in Tenant that do not affect Tenant's credit or otherwise
negatively impact Tenant's ability to comply with Lease, will be approved by
Landlord. The above prohibition of assignment will not apply in the case of a
registered offering of shares by Tenant or the public trading of registered
shares subsequent to an initial offering.

     13.02  Consent Required. Any assignment or subletting without Landlord's
            ----------------                                                 
consent shall be void, and shall constitute a default hereunder which, at the
option of Landlord, shall result in the termination of this Lease or exercise of
Landlord's other remedies hereunder. Landlord's consent cannot be unreasonably
withheld.

     13.03  Landlord's Right in Event of Assignment. If this Lease is assigned
            ---------------------------------------                           
or if the Premises or any portion thereof are sublet or occupied by any person
other than the Tenant, Landlord may collect rent and other charges from such
assignee or other party, and apply the amount collected to the rent and other
charges reserved hereunder, but such collection shall not constitute consent or
waiver of the necessity of consent to such assignment, subleasing, or other
transfer, nor shall such collection constitute the recognition of such assignee,
sublessee, or other party as the Tenant hereunder or a release of Tenant from
the further performance of all of the covenants and obligations, including
obligation to pay rent, of Tenant herein contained. In the event that Landlord
shall consent to a sublease or assignment hereunder, Tenant shall pay to
Landlord reasonable fees, not to exceed $1,000.00, incurred in connection with
processing of documents necessary to the giving of such consent.

     13.04  Assignment by Landlord. Landlord may assign or pledge its interest
            ----------------------                                            
in this Lease without limitation, provided any such assignment or pledge shall
not release Landlord from any of its duties, responsibilities or obligations
herein.

untenantable, or (b) the Premises should be damaged as a result of a risk which
is not covered by Landlord's insurance, or (c) the Premises should be damaged in
whole or in part during the last two (2) years of the Term or of any Renewal

cancellation within sixty (60) days after such event and thereupon this Lease
shall expire, and Tenant shall vacate and surrender the Premises to Landlord.
Tenant's liability for rent upon the termination of this Lease shall cease as of
the day following Landlord's giving notice of cancellation. In the event
Landlord elects to repair any damage, any abatement of rent shall end five (5)
days after notice by Landlord to Tenant that the Premises have been repaired.
Unless this Lease is terminated by Landlord or by Tenant, as permitted herein,
Tenant shall repair and re-fixture the interior of the Premises in a manner and
in at least a condition equal to that existing prior to the destruction or
casualty and the proceeds of all insurance carried by Tenant on its property and
fixtures shall be held in trust by Tenant for the purpose of said repair and
replacement.

     B.     Tenant's Options. In the event that the Premises are damaged for any
            ----------------

thirty (30) days or more, Tenant shall have the right to terminate this Lease by
giving written notice of such termination to Landlord no later than forty-five
(45) days after the occurrence of such damage. Upon such termination, Tenant's
obligations hereunder and each of them, including the obligation to pay rent of
any kind or nature, shall cease as of the day the Premises were so damaged.

business operations because of such casualty damage, rent of any kind or nature
due hereunder shall be abated for such portion of the Premises which Tenant
cannot reasonably occupy and use.

     In the event the Premises are partially damaged by fire or other casualty
and Tenant is able to carry on its normal business operations, Tenant shall pay
rent for only such portion of the Premises which Tenant may reasonably occupy or
use during the time required to make repairs. All repairs necessary to restore
the Premises to its original condition shall be commenced within sixty

the Building is condemned or acquired in lieu of condemnation for any public or
quasi-public use or purpose, by right of eminent domain or otherwise, and Tenant
is substantially unable to carry on its normal business operations for a period
of thirty (30) days or more, Tenant shall have the right to terminate this Lease
by giving written notice of such termination to Landlord no later than forty-
five (45) days after the occurrence of such condemnation. Upon such termination,
Tenant's obligations hereunder and each of them, including the obligation to pay
rent of any nature, shall cease as of the day Tenant vacates the Premises.
During any period that Tenant is unable to conduct its normal business
operations because of such condemnation, rent of any kind or nature due
hereunder shall be abated for such portion of the Premises which Tenant cannot
reasonably occupy and use. Tenant may make a separate claim against the
condemning authority for an award for the value of any of Tenant's tangible
personal property and trade fixtures, for moving and relocation expenses and for
such business damages and/or consequential damages as may be allowed by law.

     In the event the Premises are partially condemned and Tenant shall
determine that it is able to carry on its normal business operations, Tenant
shall pay rent for only such portion of the Premises which Tenant may reasonably
occupy and use during the time after such partial condemnation. Any repairs
necessary to restore the Premises to a tenantable condition after a partial
condemnation shall be undertaken by Landlord in a reasonable and prompt manner.

     18.02  Total Condemnation. In the event the entire Building be acquired
            ------------------                                              
under the power of eminent domain proceedings during the Term or Renewal Term
including any renewal period or in the event of a partial acquisition whereby
the portion of said Building remaining after such acquisition shall not be
suitable or adequate for the uses and purposes for which the Premises then are
being utilized by Tenant, then and in any such event, this Lease Agreement shall
be terminated upon the date the entire Building or portion is acquired, and no
further rent shall be due the Landlord from the Tenant. Upon such termination
each party shall be entitled to any award of condemnation depending upon their
proportionate interest in the entire Property as their interests appear in this
Lease. The Landlord shall be entitled to the distributive part of the award that
represents its ownership of the Building and the Land and the Tenant, providing
Tenant is not in default of any of the terms of this lease, shall be entitled to
its share of any award representing the value of its leasehold interest in the
Premises to be taken or condemned (and the value of any fixtures or equipment
owned by the Tenant and which have not become the properly of Landlord by virtue
of this Lease and located on the Premises, or the part taken or condemned, to
the extent that any such fixtures are taken or condemned).

     18.03  Landlord's Option to Terminate. Notwithstanding anything to the
            ------------------------------                                 
contrary, if more than fifty percent (50%) of the total floor area of the
building in which the Premises are located shall be taken as aforesaid, Landlord
may, by written notice to Tenant, terminate this Lease. If this Lease is
terminated as provided in this Section, rent shall be paid up to the day that
possession is so taken by public authority and Landlord shall make an equitable
refund of any rent paid by Tenant for periods subsequent to such termination
date.

                          EVENTS OF DEFAULT: REMEDIES
                          ---------------------------

     19.01  Default by Tenant. Upon the occurrence of any of the following
            -----------------                                             
events Landlord shall have the remedies set forth in Section 19.02.

     A.  Tenant fails to pay any rental or any other sum due hereunder within
ten (10) days after Tenant receives written notice of an amount due for rental
or otherwise.

     B.  Tenant fails to perform any other term, condition, or covenant to be
performed by it pursuant to this Lease within thirty (30) days after the written
notice of such default shall have been given to Tenant by Landlord. The thirty
(30) and ten (10) day rights to cure provided in Section 23.01 shall not be in
addition to but the same (concurrent) period as provided in this paragraph.

     C.  Tenant or its agent shall falsify any information required to be
furnished to Landlord.

     D.  Tenant shall become bankrupt or insolvent or file any debtor
proceedings or have taken against such party in any court pursuant to state or
federal statute, a petition in bankruptcy or insolvency, reorganization, or
appointment of a receiver or trustee; and such proceeding shall not be
dismissed, discontinued or vacated within thirty (30) days from the filing or
appointment.

     E.  The doing, or permitting to be done, by Tenant of any act which creates
a mechanic's lien or claim against the Land or Building of which the Premises
are a part if not released or otherwise provided for by indemnification
satisfactory to Landlord within thirty (30) days thereafter.

     19.02  Remedies. Upon the occurrence of the events set forth in Section
            --------                                                        
19.01, Landlord shall have the option to take any or all of the following
actions, without further notice of demand of any kind to Tenant or any other
person:

     A.  Immediately re-enter and remove all persons and property from the
Premises, storing said property in a public place, warehouse, or elsewhere at
the cost of, and for the account of, Tenant, all without service of notice or
resort to legal process and without being deemed guilty of or liable in
trespass. No such re-entry or taking possession of the Premises by Landlord
shall be construed as an election on its part to terminate this Lease unless a
written notice of such intention is given by
<PAGE>
 
                                      24

Landlord to Tenant. No such action by Landlord shall be considered or construed
to be a forcible entry.

     B.  Collect by suit or otherwise each installment of rent or other sum as
it becomes due hereunder, or enforce, by suit or otherwise, any other term or
provision on the part of Tenant required to be kept or performed.

     C.  Terminate this Lease by written notice to Tenant. In the event of such
termination, Tenant agrees to immediately surrender possession of the Premises.
Should Landlord terminate this Lease, it may recover from Tenant all reasonable
damages it may incur by reason of Tenant's breach, including the reasonable cost
of recovering the Premises, reasonable attorney's fees, and the worth at the
time of such termination of the excess, if any, of the amount of rent and
charges equivalent to rent reserved in this Lease for the remainder of the
stated term over the then-reasonable rental value of the Premises for the
remainder of the stated term, all of which amounts shall be immediately due and
payable from Tenant to Landlord, excluding any unexercised Renewal Term. In
determining the rent which would be payable by Tenant subsequent to default, the
rent for each year of the unexpired Term shall be equal to the average minimum
rent and additional rents paid by Tenant from the Commencement Date to the time
of default, or during the preceding full calendar year, whichever period is
shorter.

     D.  Should Landlord re-enter, as provided above, or should it take
possession pursuant to legal proceedings or pursuant to any notice provided for
by law, and whether or not it terminates this Lease, it may make such reasonable
alterations and repairs as may be necessary in order to relet the Premises, and
relet the same or any part for such term or terms (which may be for a term
extending beyond the term of this Lease) and at such reasonable rental or
rentals and upon such other terms and conditions as Landlord in its sole
discretion may deem advisable. Upon each such reletting all rentals received by
the Landlord from such reletting shall be applied, first, to the payment of any
indebtedness other than rent due hereunder from Tenant to Landlord; second, to
the payment of any costs and expenses of such reletting, including reasonable
brokerage fees and reasonable attorney's fees and reasonable costs of any
alterations and repairs; third, to the payment of rent due and unpaid, and the
residue, if any, shall be held by Landlord and applied in payment of future rent
as the same may become due and payable. If such rentals received from such
reletting during any month be less than that to be paid during such month by
Tenant, Tenant shall pay any such deficiency to Landlord. Such deficiency shall
be calculated and paid monthly. No such reentry and reletting of the Premises by
Landlord shall be construed as an election on its part to terminate this Lease
unless a written notice of such intention be given to Tenant pursuant to
subparagraph C. above. Notwithstanding any such reletting without termination,
Landlord may at any time thereafter elect to terminate this Lease for such
previous breach. The remedies given to Landlord in this Section 19.02 shall be
in addition and supplemental to all other rights or remedies which Landlord may
have under laws then in force.

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

     20.01  Liquidation. In the event that Tenant shall become a debtor under
            -----------

                                                              -- ---      
"Bankruptcy Code"), and Tenant's trustee or Tenant shall elect to assume this
Lease for the purpose of assigning the same or otherwise, such election and
assignment may be made only if the provisions of this Article XX are satisfied.
If Tenant or Tenant's trustee shall fail to elect to assume this Lease within 60
days after the filing of such petition or such additional time as provided by
the court within such 60-day period, this Lease shall be deemed to have been
rejected. Immediately thereupon Landlord shall be entitled to possession of the
Premises without further obligation to Tenants or Tenant's trustee and this
Lease shall terminate, but Landlord's right to be compensated for damages in any
such proceeding shall survive.

     20.02  Reorganization. In the event that a petition for reorganization or
            --------------                                                    
adjustment of debts is filed concerning Tenant under Chapter 11 of the
Bankruptcy Code, or a proceeding is filed under Chapter 7 of the Bankruptcy Code
and is transferred to Chapter 11, Tenant's trustee or Tenant, as debtor-in-
possession, must elect to assume this Lease within 120 days from the date of the
filing of the petition under Chapter 11 or Tenant's trustee or the debtor-in-
possession shall be deemed to have rejected this Lease. In the event that
Tenant, Tenant's trustee or the debtor-in-possession has failed to perform all
of Tenant's obligations under this Lease within the time periods (excluding
grace periods) required for such performance, no election by Tenant's trustee or
the debtor-in-possession to assume this Lease, whether under Chapter 7 or
Chapter 11, shall be effective unless each of the following conditions has been
satisfied:

     A.  Tenant's trustee or the debtor-in-possession has cured all defaults
under the Lease, or has provided Landlord with Assurance (as defined below) that
it will cure, (1) all defaults susceptible of being cured by the payment of
money within ten (10) days from the date of such assumption and (2) all other
defaults under this Lease which are susceptible of being cured by the
performance of any act promptly after the date of such assumption.

     B.  Tenant's trustee or the debtor-in-possession has compensated, or has
provided Landlord with Assurance that within ten (10) days from the date of such
assumption it will compensate Landlord for any actual pecuniary loss incurred by
Landlord arising from the default of Tenant, Tenant's trustee, or the debtor-in-
possession indicated in any statement of actual pecuniary loss sent by Landlord
to Tenant's trustee or the debtor-in-possession.

     C.  Tenant's trustee or the debtor-in-possession has provided Landlord with
Assurance of the future performance of such of the obligations under this Lease
of Tenant, Tenant's trustee or the debtor-in-possession, and if Tenant's trustee
or the debtor-in-possession has provided such Assurance. Tenant's trustee or the
debtor-in-possession shall also (1) deposit with Landlord, as security for the
timely payment of rent hereunder, an amount equal to three (3) months' Rent as
<PAGE>
 
                                      26

contained herein and (2) pay in advance to Landlord on the date any rent is due
and payable, one-twelfth (1/12th) of Tenant's annual obligations for Additional
Rent pursuant to this Lease. The obligations imposed upon Tenant's trustee or
the debtor-in-possession shall continue with respect to Tenant or any assignee
of this Lease after the completion of bankruptcy proceedings.

     D.  Such assumption will not breach or cause a default under any provision
of any other lease, mortgage, financing agreement or other agreement by which
Landlord is bound relating to the Building.

     For purposes of this Article XX, Landlord and Tenant acknowledge that
"Assurance" shall mean no less than Tenant's trustee or the debtor-in-possession
has and will continue to have sufficient unencumbered assets after the payment
of all secured obligations and administrative expenses to assure Landlord that
sufficient funds will be available to fulfill the obligations of Tenant under
this Lease and there shall have been deposited with Landlord, or the sufficient
cash payable to Landlord, and/or Tenant's trustee or the debtor-in-possession,
acceptable as to the value and kind to Landlord, to secure to Landlord the
obligation of Tenant, Tenant's trustee or the debtor-in-possession to cure the
defaults under this Lease, monetary and/or non-monetary, within the time periods
set forth above.

     20.03  Subsequent Liquidation or Petition. In the event that this Lease is
            ----------------------------------                                 
assumed in accordance with Section 20.02 and thereafter Tenant is liquidated or
files a subsequent petition for reorganization or adjustment of debts under
Chapter 11 of the Bankruptcy Code, Landlord may, at its option, terminate this
Lease and all rights of Tenant hereunder, by giving Tenant notice of its
election so to terminate within thirty (30) days after the occurrence of either
of such events.

     20.04  Assignment.
            ---------- 

     A.  If Tenant's trustee or the debtor-in-possession has assumed the Lease
pursuant to the terms and provisions of Section 20.01 or 20.02 for the purpose
of assigning (or elects to assign) this Lease to an assignee, this Lease may be
so assigned only if the proposed assignee has provided adequate assurance of
future performance of all of the terms, covenants and conditions of this Lease
to be performed by Tenant. As used herein, "adequate assurance of future
performance" shall mean that no less than each of the following conditions shall
have been satisfied.

            (1) The proposed assignee has furnished Landlord with either (a) a
     current financial statement audited by a certified public accountant
     indicating a net worth and working capital in amounts which Landlord
     reasonably determines to be sufficient to assure the future performance by
     such assignee of Tenant's obligations under this Lease or (b) a guaranty,
     or guaranties, in form and substance satisfactory to Landlord from one or
     more persons with a net worth and working capital in amounts which
     Landlord reasonably determines to be sufficient to assure the future
     performance of Tenant's obligations under this Lease.
<PAGE>
 
                                      27

            (2) Landlord has obtained from others required under any lease,
     mortgage, financing arrangement or other agreement by which Landlord is
     bound all consents or waivers necessary to permit Landlord to consent to
     such assignment.

            (3) The proposed assignment will not release or impair any guaranty
     of the obligations of Tenant (including the proposed assignee) under this
     Lease.

     B.  Any and all monies or other considerations payable or otherwise to be
delivered in connection with the assignment referred to in subparagraph A., next
above, shall be paid or delivered to Landlord, shall be and remain the exclusive
property of Landlord and shall not constitute property of Tenant or of the
estate of Tenant within the meaning of the Bankruptcy Code. Any and all monies
or other considerations constituting Landlord's property under the preceding
sentence not paid or delivered to Landlord shall be held in trust for the
benefit of Landlord and be promptly paid to or turned over to Landlord.

     C.  Any person or entity to which this Lease is assigned pursuant to the
provisions of the Bankruptcy Code shall be deemed without further act or deed to
have assumed all of the obligations arising under this Lease on and after the
date of such assignment. Any such assignee shall upon demand execute and deliver
to Landlord an instrument confirming such assumption.

     20.05  Reasonable Charges. When, pursuant to the Bankruptcy Code, Tenant's
            ------------------                                                 
trustee or the debtor-in-possession shall be obliged to pay reasonable use and
occupancy charges for the use of the Premises, such charges shall not be less
than the Rent, Additional Rent, and other sums payable by Tenant under this
Lease.

     20.06  Consent. Neither in whole nor any portion of Tenant's interest in
            -------                                                          
this Lease or its estate in the Premises shall pass to any trustee, receiver,
assignee for the benefit of creditors, or any other person or entity, or
otherwise by operation of law under the laws of any state having jurisdiction of
the person or property of the Tenant unless Landlord shall have consented to
such transfer in writing. No acceptance by Landlord of Rent or any other
payments from any such trustee, receiver, assignee, person or other entity shall
be deemed to constitute such consent by Landlord, nor shall it be deemed a
waiver of Landlord's right to terminate this Lease for any transfer of Tenant's
interest under this Lease without such consent.

under this Lease unless and until (i) Tenant shall fail to cure the same within
ten (10) days after written notice to do so from Landlord in the event the
default relates to the non-payment of rentals, or (ii) Tenant shall fail to
commence to cure a nonpayment default in good faith' within thirty (30) days
after a written notice from Landlord to do so and to promptly prosecute the same
to completion in the event the default relates to matters other than the non-
payment of rentals. If Tenant should breach this Lease or be in non-compliance
and not cure this Lease within the time limits subscribed, then Landlord shall
have the rights as described herein.

     23.02  Landlord's Right to Cure. In the event of breach, default, or

noncompliance hereunder by Landlord, Tenant shall, before exercising any right
or remedy available to it, give Landlord written notice of the claimed breach,
default, or noncompliance. If prior to its giving such notice Tenant has been
notified in writing (by way of Notice of Assignment of Rents and Leases,

                                      29

financing referred to in Article XXI hereof, concurrently with giving the
aforesaid notice to Landlord, Tenant shall, by registered mail, transmit a copy
thereof to such lender. For the thirty (30) days following the giving of the
notice(s) required by the foregoing portion of this paragraph (or such longer
period of time as may be reasonably required to cure a matter which, due to its
nature, cannot reasonably be rectified within thirty (30) days, Landlord shall
have the right to cure the breach, default, or noncompliance involved. If
Landlord has failed to cure a default within said period, any such lender shall
have an additional thirty (30) days within which to cure the same or, if such
default cannot be cured within that period, such additional time as may be
necessary if within such thirty (30) day period lender has commenced and is
diligently pursing the actions or remedies necessary to cure the breach,
default, or noncompliance involved (including, but not omitted to, commencement
and prosecution of proceedings to foreclose or otherwise exercise its rights
under its mortgage or other security instrument, if necessary to effect such
cure), in which event this Lease shall not be terminated by Tenant so long as
such actions or remedies are being diligently pursued by said lender and
provided the breach, default or noncompliance does not unreasonably interfere
with Tenant's use of the Premises.

Landlord, and shall repair any damage caused by such property or the removal.

alteration or addition made by Tenant when the alteration or addition was
approved by Landlord, then Tenant need not remove the alteration or addition
upon surrender of the Premises. If Tenant fails to remove its personal property

shall be deemed abandoned and shall become the property of Landlord, or at
Landlord's option, the same may be removed and disposed of at Tenant's expense.

     THIS AMENDMENT TO LEASE (the "Amendment") is made and entered into this 7th
day of November, 1997, by and between ICON HEALTH & FITNESS, INC., a Delaware
corporation ("ICON") and TELTRUST, INC., ("Teltrust").

                                  WITNESSETH:

Agreement, covering the real property described therein (hereinafter the
"Property"); and

     WHEREAS, Teltrust has requested ICON to sign certain lending documents in
favor of Fleet National Bank ("Bank") in connection with a loan from Bank to
Teltrust.

     NOW THEREFORE, in consideration of the mutual promises and covenants set
forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are acknowledged, ICON and Teltrust hereby agree as
follows:

     1.   Paragraphs 5.04A. and 5.04B. of said Lease are stricken and amended
to read as follows:

          A.   Amount. Within five (5) days of Tenant's execution of this 
               ------     
          Amendment the Tenant will (i) pay the sum of $50,000.00 to ICON; and

               -----------

          Sublease Agreement.

     3.   In the event of any inconsistency between the term of this Amendment
and the terms of the Lease, the terms of this Amendment shall control. Except as

     THIS AMENDMENT TO LEASE AGREEMENT is made and entered into as of the _____
day of March, 1998, by and between HOLLADAY BUILDING L.L.C. ("Lessor") and
TELTRUST, INC. ("Lessee").


                               R E C I T A L S: 

     A.  Icon Health & Fitness, Inc. ("Icon"), as lessor, and Lessee previously
entered into a Lease Agreement dated March 24, 1997 ("the Lease") for premises
in the building presently known as the HealthRider Building, which is located at
6322 South 3000 East, Salt Lake County, Utah ("the Building").

     B.  Lessor purchased the Building from Icon, and Icon assigned all of its
rights, title and interest under the Lease to Lessor.

     C.  Lessee desires to terminate its possession of certain space on the
first floor of the Building and to acquire additional space in the Building.

     D.  The parties have agreed to modify other portions of the Lease as set
forth hereinafter.

     NOW, THEREFORE, in consideration of their mutual promises and covenants set
forth hereinafter, the parties agree as follows:

     1.  TERMINATION OF OCCUPANCY OF FIRST FLOOR SPACE. On or before March 15,
1998 Lessee shall terminate its occupancy of all space that it occupies on the
first floor of the Building, which consists of 1,093 rentable square feet.
Lessee's monthly lease payments under the Lease shall be reduced by $1,343.48
per month as of the date Lessee terminates its possession of the first floor
space. Lessor shall give Lessee a credit against the next month's rent for the
reduced rent on the vacated space.

     2.  LEASE OF NEW PREMISES. Lessor hereby leases to Lessee and Lessee rents
from Lessor certain space designated as suites L1E, L3C, BIW and L1C, consisting
of approximately 32,654 rentable square feet, as specified on Schedule A
attached hereto and included herein by this reference ("the New Premises").

     3.  COMMISSIONS AND FEES. Lessee shall be solely responsible for paying any
brokerage commissions or consulting fees with respect to the lease of the New
Premises, including any consulting fees owed to Mohr Partners, Inc..

     4.  TERM OF LEASE FOR NEW PREMISES. The term of the Lease for the New
Premises shall commence on March 15, 1998 and shall terminate on March 31, 2004.
<PAGE>
 
     5.  RENT FOR NEW PREMISES. Lessee shall pay Lessor as rent for the use of
the New Premises $14.75 per rentable square foot per annum. Such rent shall be
payable monthly in advance on or before the first day of each month. As it
applies to the New Premises, the Lease shall be a triple net lease; and Lessee
shall be obligated to pay its share of operating expenses for the Building,
which Lessor estimates will be $5.00 per square foot of rentable space. (See
Schedule B attached hereto and included herein by this reference). The estimated
monthly payment for operating expenses shall be $13,605.83 per month. Should
Lessee occupy a portion but less than all of the New Premises prior to May 1,
1998, rent and Lessee's share of operating expenses for the New Premises shall
be prorated. Should Lessee occupy any portion of the New Premises on any day
other than the first day of the month, rent and Lessee's share of operating
expenses shall be prorated. Commencing May 1, 1998 and continuing through April
30, 1999, the rent for the New Premises shall be $40,137.21 per month. On May 1,
1999 and on the corresponding date of each year thereafter through March 31,
2004, rent for the New Premises shall increase by 2.5% over the monthly rent
paid during the preceding year.

proportionate share of the Kitchen/Dining Area. The parties acknowledge that as
of the date of this Amendment, Lessee's proportionate share of the
Kitchen/Dining Area is 1,914 square feet and that such number is included in the
net rentable square footage specified in paragraph 2 above. Lessee's
proportionate share of such Area is determined by multiplying the total area of
the Kitchen/Dining Area by a fraction, the numerator of which is the gross
rentable square footage of the New Premises and the denominator of which is the
gross rentable square footage of the Building. Lessee's share of the
Kitchen/Dining Area shall be subject to adjustment due to increases or decreases
in the gross rentable square footage of the Building. In the event there is a
change in the gross rentable square footage of the Building at any time,
Lessee's share of the rent shall be prorated as of the date of such change.

     7.  RENEWAL OPTIONS. Lessee shall have the option to extend the lease on
the New Premises for two (2) terms of five (5) years each, provided Lessee is
not in default of any provision of the Lease or this Amendment at the time such
option is exercised. The rent at the commencement of each extension term shall
be five percent (5%) below the then current market rate; provided, however, on
May 1st of the second, third, fourth and fifth years of each option term the
rent shall increase by 2.5% over the monthly rate paid during the preceding
year. In the event Lessee desires to exercise its option to extend the term of
the Lease on the New Premises, Lessee shall give Lessor written notice not less
than 180 days prior to the expiration of the current term of the Lease. Lessee
shall be solely responsible for the payment of any brokerage commissions or
consulting fees with respect to such extensions, including but not limited to
any consulting fees owed to Mohr Partners, Inc.

     8.  SIGNING BONUS. Upon execution of this Amendment, Lessor shall credit
Lessee with the sum of Three Hundred Twenty-Five Thousand Dollars ($325,000.00).

consulting fees owed by Lessee.

     9.  PLANS AND SPECIFICATIONS. Lessee shall be solely responsible for paying
for plans and specifications with respect to the New Premises.

     10. SECURITY DEPOSIT. lessee shall not be required to pay a security
deposit with respect to its lease of the New Premises. Lessor shall cooperate
with Lessee to obtain the return of the security deposit in the amount of 
$188,515.48 currently being held in escrow at Zions First National Bank ("the
Bank"). The parties acknowledge that Lessee shall be responsible for preparing
the necessary documents to obtain the release of the security deposit from the
Bank; and upon completion of such documents, Lessor agrees to sign the same.

     11. ADDITIONAL PARKING. Lessor shall provide Lessee with 140 parking spaces
in addition to those provided under the Lease. Lessee may rent on a month to
month basis up to four (4) additional underground parking stalls at a cost of
$40 per stall per month (the monthly charge being subject to increase from time
to time).

     12. LESSOR'S AGENT. Lessor hereby represents to Lessee that Lessor's agent
with respect to any and all matters regarding the Lease, this Amendment, the
Building and the New Premises is Beckstrand & Associates L.L.C. Lessee shall
direct any and all notices or other correspondence under the Lease or this
Amendment to Beckstrand & Associates L.L.C. at the address to which Lessee makes
its rent payments.

     13. LEASE PROVISIONS. The terms and conditions of the Lease are
incorporated herein and made a part hereof.  Except as expressly amended herein,
the terms and conditions of the Lease shall remain in full force and effect. In
the event of any inconsistency between the provisions of this Amendment and the
Lease, the provisions of this Amendment shall control.

     14. OPTION FOR ADDITIONAL SPACE. Provided this Lease is in full force and 
effect with no delinquencies or defalcations of any kind by Lessee hereunder,
Lessee shall have and is hereby granted an option to lease all or any portion of
the space in any addition to the Building. Rent for the space shall be the
current market rate for similar space in similar buildings. Prior to listing
space in an addition to the Building with a broker, Lessor shall give Lessee
written notice that such space will be available and the rate or rates for such
space. Lessee shall have a period of thirty (30) days after receiving written
notice from Lessor within which to exercise its option to rent the space in the
addition to the Building. If Lessee exercises its option to rent all or any
portion of the space in the addition, Lessee shall give Lessor written notice of
its exercise, specifying the amount of space that Lessee desires to lease.
Thereafter, the parties shall enter into a lease for such space for a term of
not less than ten (10) years on the same general covenants and conditions as set
forth in the Lease and this Amendment. If Lessee does not exercise its option to
lease any of the space in the addition, Lessee's option shall terminate, and
Lessor may lease the space in the addition to one or more tenants on such terms
and conditions as Lessor determines.

owned or hereafter acquired in and to the Lease and the leasehold estate
pursuant to that certain Leasehold Deed of Trust dated November 7, 1997 ("the

approves of the execution and delivery by Lessee of any amendments of or
modifications to such Leasehold Deed of Trust to reflect the modification to the
Lease made by this Agreement, including the change in the premises to be

the modified terms of the Lease. Lender also agrees to execute, and to use its
good faith efforts to cause any mortgagee to execute, a Subordination, Non-
disturbance and Attornment Agreement in substantially the form attached hereto
as Exhibit D and to use its good faith efforts to obtain the consent of any

and year first above written.

     Attn: Stephen J. Healey


Gentlemen:

     Reference is hereby made to the following:

          A.   Teltrust, Inc., as tenant (the "Tenant") and the undersigned, as
     landlord (the "landlord") entered into a lease dated March 24,1997) (as it
     may be hereafter amended, modified or supplemented, the "Lease", for
     premises situated at 6350 South 3000 East, Salt Lake City, State of Utah,
     as more particularly described in the Lease (the "Premises"); and

          B.   We are informed that Tenant, and certain related corporations,
     are the Borrower or one of the Guarantors under the terms of a Credit
     Agreement, dated on or about the date hereof (as amended from time to time,
     the "Credit Agreement") pursuant to which Fleet National Bank (the
     "Lender") and the lenders listed in Schedule 2. 1 to the Credit Agreement
     agreed to make certain Revolving Credit Loans and other extensions of
     credit to the Borrower, as defined in the Credit Agreement (the "Loan").

     We are also informed that it is a condition precedent to the Lender's
obligation to make the Loan that Landlord execute and deliver this letter to
Lender.

     Accordingly, in order to induce Lender to make the Loan and in
consideration therefore, and in consideration of the mutual covenants set forth
herein. Lender and Land1ord agree as follows;
<PAGE>
 
November 7, 1997
Page 2



     1.   Landlord hereby consents to and approves of the execution and delivery
by Tenant of a Mortgage (the "Mortgage") to Lender, pursuant to which Tenant
will grant a mortgage lien on all of its right, title and interest in and to the
Lease and the leasehold estate in the Premises, assign all leases, subleases,
rents and profits and grant other security interests in the Premises, in favor
of Lender as security for the payment or performance of all or the indebtedness,
liabilities and obligations, whether now existing or hereafter arising, of
Tenant to Lender.

     2.   The Landlord agrees that upon the occurrence of a default under the
Lease, Landlord will send to Lender a copy or any written notice of such default
at the same time such notice ("Default Notice") is sent to Tenant. Landlord
shall give such Default Notice to Lender at the address set forth above, or to
such other address as Lender shall designate to Landlord in writing. Notices
given Lender shall be deemed received by Lender on the same terms and conditions
as deemed to be received by Tenant as provided in the Lease.

     3.   The Landlord agrees that Landlord will accept the cure of a default
whether provided by Lender or by Tenant as specified in a Default Notice.

     4.   The Landlord acknowledges that this letter serves as a notification of
the Lender's interest in the Premises as prescribed by the Lease.
Notwithstanding any prohibition or condition on such assignments in the Lease,
and provided that Lender obtains Landlord's prior written consent, which consent
shall not be unreasonably withheld, Landlord agrees that the Lease may be
assigned in connection with the foreclosure of the Mortgage, or any action in
lieu of foreclosure of the Mortgage, and may be assigned by Lender following
such foreclosure of the Mortgage of the Lease or by assignment in lieu of
foreclosure.

     5.   Landlord agrees that at Lender's request Landlord will, if necessary,
and provided Landlord determines in its sole discretion that it is in Landlord's
best interest to do so, at the sole cost and expense of Lender, cooperate in the
prosecution of the proceedings to evict Tenant if Tenant is in default. Landlord
shall be paid by Lender, in advance, for any reasonable costs and fees Landlord
reasonably anticipates incurring in such proceedings and providing such
cooperation.

     6.   The Landlord represents to Lender that:

          (a)  As of the date of this Agreement, Tenant has paid all rent,
additional rent, and other charges and amounts due to Landlord under the Lease
or with respect to the Premises;

          (b)  Except for the rents due for the month of November 1997 which are
now due and owing, no default has occurred under the terms of the Lease of which
Landlord has

knowledge and no event has occurred or failed to occur of which Landlord has
knowledge which, with the giving of notice, the passage to time, or both, would
constitute a default or event of default with respect to the Lease; and

         (c) Except for the First Amendment to Lease of even date hereof (of
which a copy is attached) the Lease has not been amended, modified, terminated
or revoked, is in full force and effect, and is binding and enforceable against
Landlord, and against Tenant in accordance with its terms.

     7.  This Agreement may not be modified, waived or amended in any respect,
except in writing, signed by Landlord and Lender, shall be binding upon and
shall inure to the benefit of the parties hereto and their respective heirs,
legal representatives, estates, successors and assigns, and shall be governed by
and construed in accordance with the laws of the State of Utah.

     8.  Landlord acknowledges and agrees that the lien and security interest of
the Lender on any equipment owned by Tenant located on the Premises shall be
superior to any lien, right, title, claim or interest that Landlords may now or
hereafter have therein. Landlord further covenants and agrees that in the event
the Lender exercises its right to take possession of or remove said equipment
from the Premises, Landlord will not hinder or interfere therewith, and Landlord
consents to the taking of possession and removal of such equipment. Should any
of the collateral constitute "fixtures," as defined in Utah Code Ann. (S)(S)
70A-9-313. Lender agrees that it shall repair, or reimburse Landlords for the
cost of repair of, any damage to the Premises caused by the removal of any
fixtures (but Lender shall not be liable for any diminution in value of the real
estate caused by the absence of the fixtures removed or by any necessity of
replacing them).

     9.  Landlord hereby consents to the filing of a notice or memorandum of
lease with respect to the Lease and the Mortgage with the Salt Lake County
Recorders Office.

                                   Very truly yours,

                             PRELIMINARY STATEMENT
                             ---------------------

     A.  Tenant has entered into a lease with Landlord dated ___________ (the
"Lease") of premises described therein (the "Premises") consisting of an
approximately _________ square foot portion of the building located at
______________________________________________. The premises are located on a
parcel of land which is more fully described in Exhibit A attached hereto
                                                ---------                
(together with the buildings and improvements thereon, called the "Property").
                                                                   --------

     B.  Mortgagee is the holder of a certain mortgage dated ________________
from the Landlord to Mortgagee encumbering the Property (the "Mortgage"). The
term "Mortgage" includes any renewal, modification, consolidation or extension
of the same, including increases thereof and supplements thereto. The Mortgage
and all documents executed in connection therewith or secured thereby are
called the "Loan Documents."

     C.  The parties desire to establish certain rights of quiet and peaceful
possession for the benefit of Tenant under the Lease and to define the terms,
covenants and conditions precedent for such additional rights.

     NOW, THEREFORE, in consideration of the foregoing arid other valuable
consideration, the receipt and sufficiency of which is acknowledged, the parties
covenant and agree as follows:

     1.  The Lease is and shall remain subject and subordinate to the lien of
the Mortgage.   

     2.  In the event of foreclosure of the Mortgage or a deed in lieu of
foreclosure or exercise of Mortgagee's rights or remedies under the Mortgage, or
the Loan Documents, Tenant shall not be made a party in any action or proceeding
to remove or evict Tenant and Mortgagee shall not disturb Tenant's possession
under the Lease during the term provided therein, including any extensions and
renewals of the Lease now provided therein, and the Lease and the rights of
Tenant thereunder shall continue as a direct Lease between
<PAGE>
 
Mortgagee, as landlord, and Tenant, as tenant and shall not be terminated or
disturbed if and so long as Tenant is not in default under the Lease of such a
nature as would permit the Landlord to terminate the Lease after the expiration
of any applicable grace period, provided that:

          (a)  Mortgagee shall not be bound by any payment made by Tenant to
Landlord more than thirty (30) clays prior to the due date thereof unless such
prepayment was required pursuant to the terms of the Lease;

          (b)  Mortgagee shall not be bound by any amendment or modification of
the Lease affecting the term or the rent made without the written consent of
Mortgagee, which consent shall not be unreasonably withheld or delayed; and

          (c)  Tenant shall not have any right to recover from Mortgagee or set
off against payments otherwise owed under the Lease (1) any damage then accrued 
as the result of any past act, omission or default of Landlord or any prior
landlord under the Lease, except to the extent such right of offset or defense
is specifically set forth in the Lease or unless Mortgagee was previously
notified of the act or event giving rise to such offset or defense, or (2) any
security deposit unless actually received by Mortgagee.

     3.   In the event of foreclosure of the Mortgage or a deed in lieu of
foreclosure, Tenant shall attorn to Mortgagee and accept Mortgagee as the
landlord under the Lease, and Mortgagee shall have all of the rights and
remedies of the Landlord under the Lease, and Mortgagee or any person
claiming thereunder shall be bound to Tenant under all of the terms, covenants
and conditions of the Lease for the balance of the term thereof remaining and
any extensions or renewals thereof.

     4.   The foregoing provisions shall be self-operative. Nevertheless,
Mortgagee and Tenant agree, upon request, in the event of foreclosure of the
Mortgage or a deed in lieu thereof, to execute an instrument mutually
satisfactory to Mortgagee and Tenant in recordable form confirming the foregoing
provisions.

     5.   Tenant acknowledges and agrees that this Agreement satisfies any
condition or requirement in the Lease relating to the granting of a non-
disturbance agreement with respect to this particular holder of the Mortgage on
the Property.

     6.   Upon notice from Mortgagee in form reasonably satisfactory to Tenant
that (a) the Mortgagee has exercised its rights under the Loan Documents, which
may include but not necessarily be limited to (i) declaring a default under the
Loan Documents that has not been cured within the applicable grace or cure
periods, (ii) foreclosure of the Mortgage, (iii) acceptance of a deed from the
Landlord in lieu of foreclosure, or (iv) any one or more of the foregoing or
other rights exercised under the Loan Documents which may or may not involve

                                      -2-
<PAGE>
 
the Mortgagee's actual possession of the Property, and (b) the Mortgagee demands
that Tenant pay its rent to Mortgagee, then Tenant shall thereafter pay all rent
and other moneys payable to Landlord under the Lease or at the direction of
Mortgagee until otherwise notified in writing by Mortgagee. Landlord
unconditionally authorizes and directs Tenant to make rental payments directly
to Mortgagee following receipt of such notice and further agrees that Tenant may
rely upon such notice without any obligation to further inquire as to whether or
not any default exists under the Mortgage or Loan Documents and that Landlord
shall have no right or claim against Tenant for or by reason of any payments of
rent or other charges made by Tenant to Mortgagee following receipt of such
notice. Landlord, its successors and assigns hereby agree to indemnify and
hold harmless Tenant against any expense, claims, losses or damages incurred
by Tenant resulting from or arising out of claims by Landlord, its successors or
assigns that such rental payments should not have been, or cannot be, made to
Mortgagee.

     7.   Tenant agrees to give Mortgagee prompt notice of any notice of default
sent to Landlord with respect to the Lease. Tenant agrees that in the event of 
any act or omission by Landlord which would give Tenant the right, either 
immediately or after any lapse of time, to terminate the Lease or to set off 
against or reduce the rent payable thereunder or to claim a partial or total 
eviction, Mortgagee shall have the same opportunity to cure such default 
available to Landlord under the Lease except Tenant shall have the right to 
terminate the Lease without giving Mortgagee notice or the opportunity to cure.

     8.   Any notice under this Agreement shall be in writing and shall be sent 
by certified or registered mail, return receipt requested or by Federal Express 
or similar overnight courier to the following address:

     If to Mortgagee:         ______________________________
                              ______________________________
                              ______________________________
                                                            
     If to Tenant:             ______________________________
                              ______________________________
                              ______________________________
                                                            
     If to Landlord:           ______________________________
                              ______________________________
                              ______________________________

     Or, in any case, to such substitute address or addresses (up to a maximum 
of two for any party) as any party may specify by notice to the other parties.

                                      -3-
<PAGE>
 
     9.   The terms "Mortgagee," "Landlord" and "Tenant" shall be construed to
include the heirs, executors, administrators, successors and assigns of the
respective parties hereto, including, in the case of Mortgagee anyone who
succeeds to title to the Property after foreclosure or a deed in lieu thereof,
and this Agreement shall inure to their benefit and be binding on them.

     10.  No modification, amendment, waiver or release of any provision of this
Agreement or of any right, obligation, claim or cause of action arising
hereunder shall be valid or effective unless in writing and signed by the party
against whom the same is sought to be asserted.

     11.  In the event that any provision or provisions of this Agreement shall
for any reason be invalid, illegal or unenforceable by the final ruling of a
court of competent jurisdiction, the remaining provisions of this Agreement
shall not be affected thereby, and in the place of such invalid, illegal or
unenforceable provision there shall be substituted a like, but valid legal and
enforceable provision which most nearly accomplishes the original intention of
the parties, as evidenced by this Agreement.

                          INDUSTRIAL LEASE AGREEMENT



THIS LEASE is made and entered as of this 1st day of May, 1994, by and between
Rockwell International Corp., a Delaware corporation (hereinafter "Landlord"),
and Teltrust, Inc., a Utah corporation (hereinafter "Tenant").

For and in consideration of the rental and of the covenants and agreements
hereinafter set forth to be kept and performed by the Tenant, Landlord hereby
leases to Tenant and Tenant hereby leases from Landlord the Premises herein
described for the term, at the rental and subject to and upon all of the terms,
covenants and agreements hereinafter set forth.


1.       PREMISES

         A. Description. Landlord hereby leases to Tenant and Tenant hereby
         rents from Landlord those certain Premises, crosshatched on Exhibit A,
         located in the City of Salt Lake, County of Salt Lake, Utah, commonly
         known as 5520 West Harold Gatty Drive and described as approximately
         30,000 sq. ft. of office space and 360 parking stalls.

         B. Work of Improvement. Tenant to supply additional improvements at
         Tenant's cost. Such improvements to be approved by Landlord. Such
         approval not to be unreasonably withheld.

         C. Additional Parking. In the event that Tenant needs additional
         parking, in excess of the 360 spaces initially provided as part of the
         Premises, then Landlord shall make reasonable efforts to provide
         additional paved parking stalls to Tenant, so long as Landlord can do
         so without, in its judgement, impairing the use and utility to Landlord
         of the remainder of the building and land of which the Premises are a
         part. In such event Landlord and Tenant shall agree upon a reasonable
         increase in the rent, in an amount sufficient to permit Landlord to
         recover, over the remainder of the Lease term, all of its costs and
         expenses incurred in providing such additional parking

2.       TERM

         A. Term. The term of this Lease shall be for two years commencing May
         1, 1994 and ending on November 30, 1996, unless sooner terminated
         pursuant to this lease. Occupancy of the Premises shall be made
         available to Tenant upon execution of this Lease by both parties.
         Additionally, Landlord shall have the right to cancel this Lease upon
         120 days written notice to Tenant. In the event that Landlord conveys
         the Premises to Nicholas & Co. or another third party, Landlord's right
         to
<PAGE>
 
         cancel this Lease, as provided in the immediately foregoing sentence,
         shall terminate.

         B. Delay in Commencement. Tenant agrees that in the event of the
         inability of Landlord to deliver possession of the Premises to Tenant
         on the commencement date set forth in Section 2A, such inability will
         not affect the validity of this Lease or the obligations of Tenant
         hereunder, but in such case Tenant shall not be obligated to pay rent
         or other monetary sums until possession of the Premises is tendered to
         Tenant. Nevertheless, if the delay in delivery of possession exceeds
         thirty (30) days, then the expiration date of the term of the Lease
         shall be extended by the period of time computed from the scheduled
         commencement date to the date possession is tendered, or the Tenant may
         cancel the lease at Tenant's option.

3.       RENT

Concurrent with the execution hereof, Tenant shall pay to Landlord the sum of
Four Thousand Six Hundred Eighty-Seven and 50/100 Dollars ($4,687.50), as rent
for the month of May, 1994. Beginning June 1, 1994, Tenant shall pay to Landlord
as rent for the Premises in advance on the first day of each calendar month of
the term of this Lease without deduction, offset, prior notice or demand, in
lawful money of the United States, the sum of Eighteen Thousand Seven Hundred
Fifty and No/100 Dollars ($18,750.00) per month.

4.       SECURITY DEPOSIT

Concurrently with Tenant's execution of this Lease, Tenant shall deposit with
Landlord the sum of Eighteen Thousand Seven Hundred Fifty and No/100 Dollars
($18,750.00). Said sum shall be held by Landlord as a security deposit for the
faithful performance by Tenant of all of the terms, covenants, and conditions of
this Lease to be kept and performed by Tenant during the term hereof. If Tenant
defaults with respect to any provisions of this Lease, including but not limited
to the provisions relating to the payment of rent and any of the monetary sums
due herewith, Landlord may (but shall not be required to) use, apply or retain
all or any part of this security deposit for the payment of any other amount
which Landlord may spend or become obligated to spend by reason of Tenant's
default or to compensate Landlord for any other loss or damage which Landlord
may suffer by reason of Tenant's default. If any portion of said deposit is so
used or applied, Tenant shall, within ten (10) days after written demand
thereof, deposit cash with Landlord in an amount sufficient to restore the
security deposit to its original amount; Tenant's failure to do so shall be a
material breach of this Lease. Landlord shall not be required to keep this
security deposit separate from its general funds, and Tenant shall not be
entitled to interest on such deposit. If Tenant shall fully and faithfully
perform every provision of this Lease to be performed by it, the security
deposit or any balance thereof shall be returned to tenant (or, at 


                                       2
<PAGE>
 
Landlord's option, to the last assignee of Tenant's interests hereunder) at the
expiration of the Lease term and after Tenant has vacated the Premises. In the
event of termination of Landlord's interest in this Lease, Landlord shall
transfer said deposit to Landlord's successor in interest, whereupon Tenant
agrees to release Landlord from all liability for the return of such deposit or
the accounting therefor.

5.       TAXATION AND COMMON AREA MAINTENANCE CHARGES

         A. Payment of Realty Property Taxes. Tenant shall pay his proportionate
         share of Real Property Taxes and common area maintenance charges
         (including but not limited to assessments against the property for
         common expenses of the Salt Lake International Center, reasonable and
         necessary expenses incurred by Landlord for the operation, cleaning,
         maintenance, repair, insurance, and management of the building and
         grounds), including utility charges where not separately metered, and
         the repair, operation, and maintenance of land common area. Such
         payment shall be made by the Tenant to the Landlord on a monthly basis.
         At year end, the actual taxes levied against property and common area
         charges incurred during that year shall be determined by Landlord, and
         any adjustment in such estimate shall be made, with additional payments
         by or refunds to Tenant as appropriate.

         B. Proration; Joint Assessment. In the event any such real property
         taxes paid by Tenant cover any period of time prior to commencement or
         after the expiration of the term of this Lease, Tenant's share of such
         taxes shall be equitably prorated to cover only the period of time
         within the fiscal tax year during which this Lease is in effect, and
         Landlord shall reimburse Tenant to the extent required. With respect to
         any assessments which may be levied against or upon the Premises, or
         under which the laws then in force may be evidenced by improvement or
         other bonds or may be paid in annual installments, only the amount of
         such annual installment (with appropriate proration for any partial
         year) and interest due thereon shall be included within the computation
         of the annual taxes and assessments levied against the Premises. In the
         event the Premises are not separately assessed, Tenant's liability
         shall be an equitable proportion of the real property taxes for all of
         the land and improvements included within the tax parcel assessed, such
         proportion to be determined by Landlord form the respective valuations
         assigned in the Assessor's worksheets or such other information as may
         be reasonably available to Landlord, with Landlord's reasonable
         determination thereof in good faith to be conclusive.

         C. Definition of "Real Property Tax". As used in this Lease, the term
         "real property tax" shall include any form of assessment, levy or tax
         (other than inheritance, estate, net income or franchise 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 or other improvement district thereof,
         whether such tax is (a) upon or with respect to the possession,


                                       3
<PAGE>
 
          leasing, operation, management, maintenance, alteration, repair, use
          or occupancy by Tenant of the Premises or any portion thereof; or (b)
          upon or measured by the value of Tenant's personal property, equipment
          or fixtures located in the Premises; or (c) upon this transaction or
          any document to which Tenant is a part creating or transferring an
          interest or an estate in the Premises; or (d) whether or not now
          customary or within the contemplation of the parties.

                  i. Tenant shall not do or permit anything to be done in or

                  increased premium as a result of such use or acts) or cause
                  the cancellation of any insurance policy covering said
                  Premises or any building of which the Premises may be a part,

                  ii. 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 or occupants of any building
                  of which the Premises may be a part or injure or annoy them or
                  use or allow the Premises to be used for any 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.

                  iii. Tenant shall not use the Premises or permit anything to
                  be done in or about the Premises which will in anyway conflict
                  with any law, statute, zoning restriction, ordinance or
                  governmental rule or regulation or requirements or duly
                  constituted public authorities now in force or which may
                  hereafter be enacted or promulgated. Tenant shall at its sole
                  cost and expense promptly comply with all laws, statutes,
                  ordinances and governmental rules, regulations or requirements
                  now in force or which may hereafter be in force and with the
                  requirements of any board of fire underwriters or other
                  similar body now or hereafter constituted relating to or
                  affecting the condition, use or occupancy of the Premises. The
                  judgment of any court of competent jurisdiction or the
                  admission of Tenant in any action against Tenant, whether
                  Landlord be a party thereto or not, that Tenant has violated
                  any law, statute, ordinance or governmental rule, regulation
                  or requirement, shall be conclusive of that fact as between
                  Landlord and Tenant.

                  limitation thereto, all plumbing, heating, air conditioning,

                  ii. Upon the expiration or earlier termination of this Lease,
                  Tenant shall surrender the Premises in the same condition as
                  received, broom clean, ordinary wear and tear and damage by
                  fire, earthquake, act of God or the elements alone excepted.
                  Tenant at its sole cost and expense, agrees to repair any
                  damage to the Premises caused by or in connection with the
                  removal of any articles or personal property, business or
                  trade fixtures, machinery, equipment, cabinetwork, furniture,

         C.       Landlord's Rights. In the event Tenant fails to perform
         Tenant's obligations under this Section 8, Landlord shall give Tenant
         notice to do such acts as are reasonably required to so maintain the
         Premises; if Tenant shall fail to commence such work and diligently
         prosecute it to completion, then Landlord shall have the right but not
         the obligation to do such acts and expend such funds at the expense of
         Tenant as are reasonably required to perform such work. Any amount so
         expended by Landlord shall be paid by Tenant promptly after demand with
         interest at ten percent (10%) per annum from the date of such work.
         Landlord shall have no liability to Tenant for any damage,
         inconvenience or interference with the use of the Premises by Tenant as
         a result of performing any such work.

         D.       Alterations and Additions.

                  i. Tenant shall not, without Landlord's prior written consent,
                  make any alterations, additions, improvements or utility
                  installations in, on or about the Premises, except for non-
                  structural alterations not exceeding $2,500 in cost. As used

                  As a condition to giving such consent, Landlord may require
                  that Tenant agree to remove any such alterations, additions,
                  improvements or utility installations at the expiration of the
                  term and to restore the Premises to their prior condition.

                  ii. Unless Landlord requires their removal as set forth in
                  Paragraph 8D, and except for those items and improvements
                  listed on Exhibit B, all alterations, additions, improvements
                  and utility installations which may be made on the Premises,
                  shall at the expiration of earlier termination of the Lease
                  become the property of Landlord and remain upon and be
                  surrendered with the Premises. Notwithstanding the provisions
                  of the immediately preceding sentence, personal property,

                  material damage to the Premises, and all of the items listed
                  on Exhibit B, shall remain the property of Tenant and may be
                  removed by Tenant subject to the provisions of Paragraph 8B,
                  at any time during the term of this Lease when Tenant is not

Tenant shall keep the Premises and any building of which the Premises are a part
free from any liens arising out of work performed, materials furnished or
obligations incurred by Tenant and shall indemnify, hold harmless and defend

ten percent (10%) per annum. Landlord shall have the right at all times to post

         harmless from and against any and all claims of liability for any
         injury or damage to any person or property arising from Tenant's use of
         the Premises, or from the conduct of Tenant's business or from any
         activity, work or thing done, permitted or suffered by Tenant in or
         about the Premises or elsewhere. Tenant shall further indemnify and
         hold Landlord 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 this Lease, or arising from any negligence
         of Tenant or Tenant's agents, contractors or employees, and from and
         against all costs, attorney's fees, expenses and liabilities incurred
         in the defense of any such claim or any action or proceeding brought
         thereon. In the event any action or proceeding is brought against
         Landlord by reason of any such claim, Tenant upon notice from Landlord
         shall defend same at Tenant's expense by counsel satisfactory to
         Landlord.

         B. Indemnification by Landlord. Landlord shall indemnify and hold
         Tenant harmless from and against any and all claims arising from any
         breach or default in the performance of any obligation on Landlord's
         part to be performed under this Lease, or arising from any negligence
         of Landlord or Landlord's agents, contractors or employees, and from
         and against all costs, attorney's fees, expenses and liabilities
         incurred in the defense of any such claim or any action or proceeding
         brought thereon. In the event any action or proceeding is brought
         against Tenant by reason of any such claim, Landlord upon notice from
         Tenant shall defend same at Landlord's expense by counsel satisfactory
         to Tenant.

         C. Exemption of Landlord from Liability. Landlord shall not be liable
         for injury to Tenant, its employees, invitees, customers, agents or
         contractors or any other person in or about the Premises, caused by or
         resulting from fire, steam, electricity, gas, water or rain, which may
         leak or flow from or into any part of the Premises, or from the
         breakage, leakage, obstruction or other defects of the pipes,
         sprinklers, wires, appliances, plumbing, air conditioning or lighting
         fixtures of the same, whether the said damage or injury results from
         conditions arising upon the Premises or upon other portions of the
         building of which the Premises are a part, or from other sources or
         places and regardless of whether the cause of such damage or injury or
         the means of repairing the same is inaccessible to Tenant. Landlord
         shall

         other tenant, if any, of the building in which the Premises are
         located.


12.      INSURANCE

         A. Liability Insurance. Tenant shall, at Tenant's expense, procure and
         maintain at all times during the term of this Lease a policy of
         comprehensive public liability insurance insuring Landlord and Tenant
         against any liability arising out of the ownership, use, occupancy, or
         maintenance of the Premises and appurtenant areas. Such insurance shall
         at all times be in an amount of not less than $1 million for injury to
         or death of any one person in any one accident or occurrence and in
         amount of not less than $3 million for liability for property damage.
         The limits of such insurance shall not limit the liability of Tenant.
         If the Premises are part of a larger property, said insurance shall
         have a Landlord's Protective Liability endorsement attached hereto. All
         insurance required hereunder shall be with companies rated A+ or
         better in "Best's Insurance Guide". Tenant shall deliver to Landlord
         certificates of insurance evidencing the existence and amounts of such
         insurance with loss payable clauses satisfactory to Landlord, provided
         that in the event Tenant fails to procure and maintain such insurance,
         Landlord may (but shall not be required to) procure same at Tenant's
         expense after ten (10) days prior written notice. No such policy shall
         be cancelable or subject to reduction of coverage or other modification
         except after thirty (30) days prior written notice to Landlord by the
         insurer. All such policies shall be written as primary policies, not
         contributing with and not in excess of coverage which the Landlord may
         carry. Tenant shall, within twenty (20) days prior to the expiration of
         such policies, furnish Landlord with renewals or binders or Landlord
         may order such insurance and charge the cost to Tenant, which amount
         shall be payable by Tenant upon demand. Tenant shall have the right to
         provide such insurance coverage pursuant to blanket policies obtained
         by Tenant provided such blanket policies expressly afford coverage to
         the Premises and to Tenant as required by this Lease.

         B. Property Insurance. Landlord shall, at Landlord's expense, procure
         and maintain at all times during the term of this Lease a policy or
         policies of insurance covering loss or damage to the Premises in the
         amount of the full replacement value thereof (exclusive of Tenant's
         trade fixtures and equipment), providing protection against all perils
         included within the classification of fire, extended coverage,
         vandalism, malicious mischief, sprinkler leakage and special extended
         peril (all risk). Tenant shall pay such annual insurance premiums to
         Landlord within fifteen (15) days after receipt by Tenant of copy of
         the premium statement or other reasonably satisfactory evidence of the
         amount due, which shall include the method of calculation of Tenant's
         share thereof if the insurance covers other improvements than the
         Premises. Such insurance shall provide for payment of loss thereunder
         to Landlord or the holder of a first mortgage or deed of trust on the
         Premises.




                                       9
<PAGE>
 
         C. Waiver of Subrogation. Landlord and Tenant each hereby waive any and
         all rights of recovery against the other or against the officers,
         employees, agents and representatives of the other, on account of loss
         or damage occasioned to such waiving party of its property or the
         property of others under its control caused by fire or any of the
         extended coverage risks described above to the extent that such loss or
         damage is insured against under any insurance policy in force at the
         time of such loss or damage. The insuring party shall, upon obtaining
         the policies of insurance required under this Lease, give notice to the
         insurance carrier or carriers that the foregoing mutual waiver of
         subrogation is contained in this Lease.


13.      DAMAGE OR DESTRUCTION

         A. Partial Damage - Insured. In the event improvements on the Premises
         are damaged by any casualty which is covered under an insurance policy
         required to be maintained pursuant to Section 12B, then Landlord shall
         repair such damage as soon as reasonably possible and this Lease shall
         continue in full force and effect.

         B. Partial Damage - Uninsured. In the event the improvements on the
         Premises are damaged, except by a negligent or willful act or omission
         of Tenant, by any casualty not covered under an insurance policy
         required to be maintained pursuant to Section 12B, then Landlord may,
         at Landlord's option, either (a) repair such damage as soon as
         reasonably possible at Landlord's expense, in which event this Lease
         shall continue in full force and effect, or (b) give written notice to
         Tenant within thirty (30) days after the date of occurrence of such
         damage of Landlord's intention to cancel and terminate this Lease as of
         the date of the occurrence of the damage. In the event Landlord elects
         to terminate this Lease pursuant to this Section 13B, Tenant shall have
         the right within ten (10) days after receipt of the required notice to
         notify Landlord in writing of Tenant's intention to repair such damage
         at Tenant's expense, without reimbursement from Landlord, in which
         event this Lease shall continue in full force and effect, and Tenant
         shall proceed to make such repairs as soon as reasonably possible. If
         Tenant does not give such notice within the ten (10) day period, this
         Lease shall be canceled and terminated as of the date of the occurrence
         of such damage.

         C. Total Destruction. If the Premises are totally destroyed during the
         term of this Lease from any cause whether or not covered by the
         insurance required under Section 12B (including any destruction
         required by any authorized public authority), this Lease shall
         automatically terminate as of the date of such total destruction.

         D. Damage Near End of The Term. If the Premises are partially destroyed
         or damaged during the last six (6) months of the term of this Lease,
         Landlord may at Landlord's option cancel and terminate this Lease as of
         the date of occurrence of such 



                                       10
<PAGE>
 
         damage by giving written notice to Tenant of Landlord's election to do
         so within thirty (30) days after the date of such damage.

         E. Landlord's Obligations. The Landlord shall not be required to repair
         any injury or damage by fire or other cause, or to make any restoration
         or replacement of any panelings, decorations, office fixtures,
         partitions, railings, ceilings, floor covering, equipment, machinery or
         fixtures or any other improvements or property installed in the
         Premises by Tenant or at the direct or indirect expense of Tenant.
         Tenant shall be required to restore or replace same in the event of
         damage.

         F. Abatement of Rent; Tenant's Remedies.

            i.  If the Premises are partially destroyed or damaged and Landlord
                or Tenant repairs them pursuant to this Lease, the rent payable
                hereunder for the period during which such damage and repair
                continues shall be abated in proportion to the extent to which
                Tenant's use of the Premises is impaired. Except for abatement
                of rent, if any, Tenant shall have no claim against Landlord for
                any damage suffered by reason of any such damage, destruction,
                repair or restoration.

            ii. If Landlord shall be obligated to repair or restore the Premises
                under this Section 13 and shall not commence such repair or
                restoration within ninety (90) days after such obligation shall
                accrue, Tenant at Tenant's option may cancel and terminate this
                Lease by written notice to Landlord at any time prior to the
                commencement of such repair or restoration. In such event this
                Lease shall terminate as of the date of such notice.

         G. Termination - Advance Payments. Upon termination of this Lease
         pursuant to Section 13, an equitable adjustment shall be made
         concerning advance rent and any advance payments made by Tenant to
         Landlord. Landlord shall, in addition, return to Tenant so much of
         Tenant's security deposit as has not theretofore been applied by
         Landlord.


14.      CONDEMNATION

If the Premises or any portion thereof are taken under the power of eminent
domain, or sold by Landlord under the threat of the exercise of said power (all
of which is herein referred to as "condemnation"), this Lease shall terminate as
to the part so taken as of the date the condemning authority takes title or
possession, whichever occurs first. If more than ten percent (10%) of the floor
area of any buildings on the Premises, or more than twenty-five percent (25%) of
the land area of the Premises not covered with buildings, is taken by
condemnation, either Landlord or Tenant may terminate this Lease, as of the date
the condemning authority takes possession, by notice in writing of such election
within twenty 



                                       11
<PAGE>
 
(20) days after Landlord shall have notified Tenant of the taking, or in the
absence of such notice then within twenty (20) days after the condemning
authority shall have taken possession.

If this Lease is not terminated by either Landlord or Tenant then it shall
remain in full force and effect as to the portion of the Premises remaining,
provided the rent shall be reduced in the proportion that the floor area of the
buildings taken within the Premises bears to the total floor area of all
buildings located on the Premises. In the event this Lease is not so terminated
then Landlord agrees, at Landlord's sole cost, to restore the Premises to a
complete unit of like quality and character as existed prior to the condemnation
as soon as reasonably possible. All awards for the taking of any part of the
Premises or any payment made under the threat of the exercise of power of
eminent domain shall be the property of Landlord, whether made as compensation
for diminution of value of a leasehold or for the taking of the fee or as
severance damages; provided, however, that Tenant shall be entitled to any award
for loss of or damage to Tenant's trade fixtures and removable personal
property. In the event that this lease is not terminated by reason of such
condemnation, Landlord shall, to the extent of severance damages received by
Landlord in connection with such condemnation, repair any damage to the Premises
caused by such condemnation except to the extent that Tenant has been reimbursed
therefor by the condemning authority. Tenant shall pay any amount in excess of
such severance damages required to complete such repair.


15.      ASSIGNMENT & SUBLETTING

         A. Landlord's Consent Required. Tenant shall not assign, transfer,
         mortgage, pledge, hypothecate or encumber this Lease or any interest
         therein, and shall not sublet the Premises or any part thereof, without
         the prior written consent to Landlord and any attempt to do so without
         such consent being first had and obtained shall be wholly void and
         shall constitute a breach of this Lease.

         B. Reasonable Consent. If Tenant complies with the following
         conditions, Landlord shall not unreasonably withhold its consent to the
         subletting of the Premises or any portion thereof. Tenant shall submit
         in writing to Landlord: (a) the name and legal composition of the
         proposed subtenant; (b) the nature of the proposed subtenant's business
         to be carried on in the Premises; (c) the terms and provisions of the
         proposed sublease; (d) such reasonable financial information as
         Landlord may request concerning the proposed subtenant.

         C. No Release of Tenant. No consent by Landlord to any assignment or
         subletting by Tenant shall relieve Tenant of any obligation to be
         performed by the Tenant under this Lease, whether occurring before or
         after such consent, assignment or subletting. The consent by Landlord
         to any assignment or subletting shall not relieve Tenant from the
         obligation to obtain Landlord's express written consent to any other
         assignment or subletting. The acceptance of rent by Landlord from any
         other 



                                       12
<PAGE>
 
         person shall not be deemed to be a waiver by Landlord of any provision
         of this Lease or to be a consent to any assignment, subletting or other
         transfer. Consent to one assignment, subletting or other transfer shall
         not be deemed to constitute consent to any subsequent assignment,
         subletting or other transfer.

         D. Attorney's Fees. In the event Landlord shall consent to a sublease
         or assignment under this Section 15, Tenant shall pay Landlord's
         reasonable attorney's fees not to exceed $500.00 incurred in connection
         with giving such consent.


16.      SUBORDINATION

         A. Subordination. This Lease, at Landlord's option, shall be subject
         and subordinate to all ground or underlying leases which now exist or
         may hereafter by executed affecting the Premises or the land upon which
         the Premises are situated or both, and the lien of any mortgages or
         deeds of trust in any amount or amounts whatsoever now or hereafter
         placed on or against the land or improvements or either thereof, of
         which the Premises are a part, or on or against Landlord's interest or
         estate therein, or on or against any ground or underlying Lease without
         the necessity of the execution and delivery of any further instruments
         on the part of the Tenant to effectuate such subordination.
         Alternatively, any mortgagee, trustee or ground lessor may elect to
         have this Lease prior to the lien of its mortgage, deed of trust or
         ground lease, whether this Lease is dated prior or subsequent to the
         date of said mortgage, deed of trust or ground lease or the date of the
         recording thereof.

         B. Subordination Agreements. Tenant covenants and agrees to execute and
         deliver upon demand without charge therefore, such further instruments
         evidencing such subordination of the Lease to such ground or underlying
         leases and to the lien of any such mortgages or deeds of trust as may
         be required by Landlord. Tenant hereby appoints Landlord as Tenant's
         attorney-in-fact, irrevocably, to execute and deliver any such
         agreements, instruments, releases or other documents.

         C. Quiet Enjoyment. Landlord covenants and agrees with Tenant that upon
         Tenant paying rent and other monetary sums due under the Lease and
         performing its covenants and conditions, Tenant shall and may peaceably
         and quietly have, hold and enjoy the Premises for the term of the
         Lease, described above.

         D. Attornment. In the event any proceedings are brought for default
         under any ground or underlying lease or in the event of foreclosure or
         the exercise of the power of sale under any mortgage or deed of trust
         made by the Landlord covering the Premises, the Tenant shall attorn to
         the purchaser upon any such foreclosure or sale and recognize such
         purchaser as the Landlord under this Lease; provided said purchaser
         expressly agrees in writing to be bound by the terms of the Lease.

17.      DEFAULT; REMEDIES

         A. Default. The occurrence of any of the following shall constitute a
         material default and breach of this Lease by Tenant:

            i.   Any failure by Tenant to pay the rent or any other monetary
            sums required to be paid hereunder (where such failure continues for
            thirty (30) days after written notice thereof by Landlord to
            Tenant);

            ii.  The abandonment or vacation of the Premises by Tenant;

            iii. A failure by Tenant to observe and perform any other provision
            of this Lease to be observed or performed by Tenant, where such
            failure continues for thirty (30) days after written notice thereof
            by Landlord to Tenant; provided, however, that if the nature of such
            default is such that the same cannot reasonably be cured within such
            thirty (30) day period, Tenant shall not be deemed to be in default
            if Tenant shall within such period commence such cure and thereafter
            diligently prosecute the same to completion;

            iv.  The making by Tenant of any general assignment or general
            arrangement for the benefit of creditors; the filing by or against
            Tenant of a petition to have Tenant adjudged a bankrupt or of a
            petition for reorganization or arrangement under any law relating to
            bankruptcy (unless, in the case of a petition filed against Tenant,
            the same is dismissed within sixty (60) days); the appointment of a
            trustee or receiver to take possession of substantially all of
            Tenant's assets located at the Premises or of Tenant's interest in
            this Lease, where possession is not restored to Tenant within thirty
            (30) days; or the attachment, execution or other judicial seizure of
            substantially all of Tenant's assets located at the Premises or of
            Tenant's interest in this Lease, where such seizure is not
            discharged within thirty (30) days.

         B. Remedies. In the event of any such material default or breach by
         Tenant, Landlord may at any time thereafter, with or without notice and
         demand and without limiting Landlord in the exercise of any right or
         remedy at law or in equity which Landlord may have by reason of such
         default or breach:

            i. Maintain this Lease in full force and effect and recover the
            rent and other monetary charges as they become due, without
            terminating Tenant's right to possession, irrespective of whether
            Tenant shall have abandoned the Premises. In the event Landlord
            elects to not terminate the Lease, Landlord shall have the right to
            attempt to re-let the Premises at such rent and upon such conditions
            and for such a term, and to do all acts necessary to maintain or
            preserve the Premises as Landlord deems reasonable and necessary
            without being deemed to have elected to terminate the Lease
            including removal of all




                                       14
<PAGE>
 
              persons and property from the Premises; such property may be
              removed and stored in a public warehouse or elsewhere at the cost
              of and for the account of Tenant. Notwithstanding that Landlord
              fails to elect to terminate the Lease initially, Landlord at any
              time during the term of this Lease may elect to terminate this
              Lease by virtue of such previous default of Tenant.

              ii. Terminate Tenant's right to possession by any lawful means, in
              which case this Lease shall terminate and Tenant shall immediately
              surrender possession of the Premises to Landlord. In such event,
              Landlord shall be entitled to recover from Tenant all damages
              incurred by Landlord by reason of Tenant's default, including
              without limitation thereto, the following: (i) the worth at the
              time of award of any unpaid rent which had been earned at the time
              of such termination; plus (ii) 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 is proved could have been reasonably
              avoided; plus (iii) 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 is
              proved could be reasonably avoided; plus (iv) 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; plus (v) 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 state law. Upon any such
              reentry Landlord shall have the right to make any reasonable
              repairs, alterations or modifications to the Premises, which
              Landlord in its sole discretion deems reasonable and necessary. As
              used in subparagraph (i) above, the "worth at the time of award"
              is computed by allowing interest at the rate of ten percent (10%)
              per annum from the date of default. As used in subparagraphs (ii)
              and (iii) the "worth at the time of award" is computed by
              discounting such amount at the discount rate of the U.S. Federal
              Reserve Bank at the time of award plus one percent (1%). The term
              "rent", as used in this Section 17, shall be deemed to be and to
              mean the rent to be paid pursuant to Section 3 and all other
              monetary sums required to be paid by Tenant pursuant to the terms
              of this Lease.

         C. Late Charges. Tenant hereby acknowledges that late payment by Tenant
         to Landlord or rent and other sums due hereunder will cause Landlord to
         incur costs not contemplated by this Lease, the exact amount of which
         will be extremely difficult to ascertain. Such costs include, but are
         not limited to, processing and accounting charges, and late charges
         which may be imposed on Landlord by the terms of any mortgage or trust
         deed covering the Premises. Accordingly, if any installment of rent or
         any other sum due from Tenant shall not be received by Landlord or
         Landlord's designee within ten (10) days after such amount shall be
         due, Tenant shall pay to 

                                       15
<PAGE>
 
         Landlord a late charge equal to ten percent (10%) of such overdue
         amount. The parties hereby agree that such late charge represents a
         fair and reasonable estimate of the costs Landlord will incur by reason
         of late payment by Tenant. Acceptance of such late charge by Landlord
         shall in no event constitute a waiver of Tenant's default with respect
         to such overdue amount, nor prevent Landlord from exercising any of the
         other rights and remedies granted hereunder.

         D. Default by Landlord. Landlord shall not be in default unless
         Landlord fails to perform obligations required of Landlord within a
         reasonable time, but in no event later than thirty (30) days after
         written notice by Tenant to Landlord and to the holder of any first
         mortgage or deed of trust covering the Premises whose name and address
         shall have theretofore been furnished to Tenant in writing, specifying
         wherein Landlord has failed to perform such obligation; provided,
         however, that if the nature of Landlord's obligation is such that more
         than thirty (30) days are required for performance, then Landlord shall
         not be in default if Landlord commences performance within such
         thirty-day period and thereafter diligently prosecutes the same to
         completion.

18.      MISCELLANEOUS

         A.       Estoppel Certificate.

                  i.   Tenant shall at any time upon not less than ten (10)
                  days' prior written notice from Landlord execute, acknowledge
                  and deliver to Landlord a statement in writing (i) certifying
                  that this Lease is unmodified and in full force and effect
                  (or, if modified, stating the nature of such modification and
                  certifying that this Lease, as so modified, is in full force
                  and effect) and the date to which the rent and other charges
                  are paid in advance, if any, and (ii) acknowledging that there
                  are not, to Tenant's knowledge, any uncured defaults on the
                  part of Landlord hereunder, or specifying such defaults if any
                  are claimed. Any such statement may be conclusively relied
                  upon by a prospective purchaser or encumbrancer of the
                  Premises.

                  ii.  Tenant's failure to deliver such statement within such
                  time shall be conclusive upon Tenant (i) that this Lease is in
                  full force and effect, without modification except as may be
                  represented by Landlord, (ii) that there are no uncured
                  defaults in Landlord's performance and (iii) that not more
                  than one month's rent has been paid in advance.

                  iii. If Landlord desires to finance or refinance said
                  Premises, or any part thereof, Tenant hereby agrees to deliver
                  to any lender designated by Landlord such financial statements
                  of Tenant as may be reasonably required by such lender. Such
                  statements shall include the past three years' financial
                  statements

                                       16
<PAGE>
 
              of Tenant. All such financial statements shall be received by
              Landlord in confidence and shall be used only for the purposes
              herein set forth.

         B.   Transfer of Landlord's Interest. In the event of a sale or
         conveyance by Landlord of Landlord's interest in the Premises other
         than a transfer for security purposes only, Landlord shall be relieved
         from and after the date specified in such notice of transfer of all
         obligations and liabilities accruing thereafter on the part of the
         Landlord, provided that any funds in the hands of Landlord at the time
         of transfer in which Tenant has an interest, shall be delivered to the
         successor of Landlord. This Lease shall not be affected by any such
         sale and Tenant agrees to attorn to the purchaser or assignee provided
         all Landlord's obligations hereunder are assumed in writing by the
         transferee.

         C.   Captions; Attachments; Defined Terms.

              i. The captions of the paragraphs of this Lease are for
              convenience only and shall not be deemed to be relevant in
              resolving any question of interpretation or construction of any
              section of this Lease.

              ii. Exhibits attached hereto, and addendum and schedules initialed
              by the parties, are deemed by attachment to constitute part of
              this Lease and are incorporated herein.

              iii. The words "Landlord" and "Tenant", as used herein, shall
              include the plural as well as the singular. Words used in neuter
              gender include the masculine and feminine and words in the
              masculine or feminine gender include the neuter. If there be more
              than one Landlord or Tenant, the obligations hereunder imposed
              upon Landlord or Tenant shall be joint and several. If the Tenants
              are husband and wife, the obligations shall extend individually to
              their sole and separate property as we as to their community
              property. The term "Landlord" shall mean only the owner or owners
              at the time in question of the fee title or a tenant's interest in
              a ground lease of the Premises. The obligations contained in this
              Lease to be performed by Landlord shall be binding on Landlord's
              successors and assigns only during their respective periods of
              ownership.

         D.   Entire Agreement. This instrument along with any exhibits and
         attachments hereto constitutes the entire agreement between Landlord
         and Tenant relative to the Premises and this Agreement and the exhibits
         and attachments may be altered, amended or revoked only by an
         instrument in writing signed by both Landlord and Tenant. Landlord and
         Tenant agree hereby that all prior or contemporaneous oral agreements
         between and among themselves and their agents or representatives
         relative to the leasing of the Premises are merged in or revoked by
         this Agreement.

                                       17
<PAGE>
 
         E.   Severability. If any term or provision of this Lease shall, to any
         extent, be determined by a court of competent jurisdiction to be
         invalid or unenforceable, the remainder of this Lease shall not be
         affected thereby, and each term and provision of this Lease shall be
         valid and be enforceable to the fullest extent permitted by law.

         F.   Costs of Suit.

              i. If Tenant or Landlord shall bring any action for any relief
              against the other, declaratory or otherwise, arising out of 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 a reasonable sum for attorneys' fees which shall
              be deemed to have accrued on the commencement of such action and
              shall be paid whether or not such action is prosecuted to
              judgment.

              ii. Should Landlord, without fault on Landlord's part, be made a
              party to any litigation instituted by any third party against
              Tenant, or for the foreclosure of any lien for labor or material
              furnished to or for Tenant, or otherwise arising out of or
              resulting from any act or transaction of Tenant, Tenant covenants
              to save and hold Landlord harmless from any judgment rendered
              against Landlord or the Premises or any part thereof, and all
              costs and expenses, including reasonable attorneys' fees, incurred
              by Landlord in or in connection with such litigation.

              iii. Should Tenant, without fault on Tenant's part, be made a
              party to any litigation instituted by any third party against
              Landlord, or for the foreclosure of any lien for labor or material
              furnished to or for Landlord, or otherwise arising out of or
              resulting from any act or transaction of Landlord, Landlord
              covenants to save and hold Tenant harmless from any judgment
              rendered against Tenant or the Premises or any part thereof, and
              all costs and expenses, including reasonable attorneys' fees,
              incurred by Tenant in or in connection with such litigation.

         G.   Time; Joint and Several Liability. Time is of the essence of this
         Lease and each and every provision hereof, except as to the conditions
         relating to the delivery of possession of the Premises to Tenant. All
         the terms, covenants and conditions contained in this Lease to be
         performed by either party, if such party shall consist of more than one
         person or organization, shall be deemed to be joint and several, and
         all rights and remedies of the parties shall be cumulative and
         non-exclusive of any other remedy at law or in equity.

         H. Binding Effect; Choice of Law. The parties hereto agree that all the
         provisions hereof are to be construed as both covenants and conditions
         as though the words importing such covenants and conditions were used
         in each separate paragraph hereof; subject to any provisions hereof
         restricting assignment or subletting by Tenant

                                       18
<PAGE>
 
         and subject to Section 19B, all of the provisions hereof shall bind and
         inure to the benefit of the parties hereto and their respective heirs,
         legal representatives, successors and assigns. This Lease shall be
         governed by the laws of the State of Utah.

         I. Waiver. No covenant, term or condition or the breach thereof shall
         be deemed waived, except by written consent of the part against whom
         the waiver is claimed, and any waiver or the breach of any covenant,
         term or condition shall not be deemed to be a waiver of any proceeding
         or succeeding breach of the same or any other covenant, term or
         condition. Acceptance by Landlord of any performance by Tenant after
         the time the same shall have become due shall not constitute a waiver
         by Landlord of the breach or default of any covenant, term or condition
         unless otherwise expressly agreed to by Landlord in writing.

         J. Surrender of Premises. The voluntary or other surrender of this
         Lease by Tenant, or a mutual cancellation thereof, shall not work a
         merger, and shall, at the option of the Landlord, terminate all or any
         existing subleases or subtenancies.

         K. Holding Over. If Tenant remains in possession of all or any part of
         the Premises after the expiration of the term hereof, with or without
         the express or implied consent of Landlord, such tenancy shall be from
         month to month only, and not a renewal hereof or an extension for any
         further term, and in such case, rent and other monetary sums due
         hereunder shall be payable in an amount equal to 150% of the rent
         charged immediately prior to expiration, and such month to month
         tenancy shall be subject to every other term, covenant and agreement
         contained herein.

         L. Signs and Auction. Tenant shall not place any sign upon the Premises
         or conduct any auction thereon without Landlord's prior written
         consent.

         M. Reasonable Consent. Except as limited elsewhere in this Lease,
         wherever in this Lease Landlord or Tenant is required to give its
         consent or approval to any action on the part of the other, such
         consent or approval shall not be unreasonably withheld. In the event of
         failure to give any such consent, the other party shall be entitled to
         specific performance at law and shall have such other remedies as are
         reserved to it under this Lease, but in no event shall Landlord or
         Tenant be responsible in monetary damages for failure to give consent
         unless said failure is withheld maliciously or in bad faith.

         N. Interest on Past Due Obligations. Except as expressly herein
         provided, any amount due to Landlord not paid when due shall bear
         interest at twelve percent (12%) per annum from the due date. Payment
         of such interest shall not excuse or cure any default by Tenant under
         this Lease.

                                       19
<PAGE>
 
         O. Recording. Tenant shall not record this Lease without Landlord's
         prior written consent, and such recordation shall, at the option of
         Landlord constitute a non-curable default of Tenant hereunder. Either
         party shall, upon request of the other, execute, acknowledge and
         deliver to the other a "short form" memorandum of this Lease for
         recording purposes.

         P. Notices. All notices or demands of any kind required or desired to
         be given by Landlord or Tenant hereunder shall be in writing and shall
         be deemed delivered forty-eight (48) hours after depositing the notice
         or demand in the United States mail, certified or registered, postage
         prepaid, addressed to the Landlord or Tenant respectively at the
         addressed set forth after their signatures at the end of this Lease.

         Q. Corporate Authority. If Tenant is a corporation, each individual
         executing this Lease on behalf of said corporation represents and
         warrants that he is duly authorized to execute and deliver this Lease
         on behalf of said corporation in accordance with a duly adopted
         resolution of the Board of Directors of said corporation or in
         accordance with the Bylaws of said corporation, and that this Lease is
         binding upon said corporation in accordance with its terms. If Tenant
         is a corporation, Tenant shall, within thirty (30) days after execution
         of this Lease, deliver to Landlord a certified copy of a resolution of
         the Board of Directors of said corporation authorizing or ratifying the
         execution of this Lease.

19.      HAZARDOUS MATERIALS

         A. Lessor's Prior Consent. Notwithstanding anything contained in this
         Lease to the contrary, Tenant shall not cause or permit any Hazardous
         Materials (as defined in Section 19B below) to be brought upon, kept,
         stored, discharged, released or used in, under or about the Premises by
         Tenant, its agents, employees, contractors, subcontractors, licensees
         or invitees, without the prior written consent of Landlord.

         B. Compliance with Hazardous Materials Laws. Tenant shall at all times
         in all respects comply will all federal, state and local laws,
         ordinances and regulations relating to or involving the use,
         generation, manufacture, storage, discharge, release, disposal or
         transportation of any materials, substances or wastes which are
         considered to be or may be hazardous to human health or safety or to
         the environment due to their radioactivity, ignitability,
         corrositivity, reactivity, carcinogenicity, infectiousness or other
         harmful properties and which are defined as or included within the
         definition of "hazardous materials," "toxic substances" or "chemical

         Materials in, on, under or about the Premises in total conformity with
         all applicable Hazardous Materials Laws and prudent industry practices
         regarding management of such Hazardous Materials. Upon expiration or
         earlier termination of this Lease, Tenant shall, at Tenant's sole cost
         and expense, cause all Hazardous Materials brought or allowed on the
         Premises during the lease term to be removed from the Premises and
         transported for use, storage or disposal in accordance and in
         compliance with all applicable Hazardous Materials Laws. Tenant shall
         not take any remedial action in response to the presence of any
         Hazardous Materials in or about the Premises or enter into any
         settlement agreement, consent decree or other compromise in respect to
         any claims relating to any Hazardous Materials in any way connected
         with the Premises, without first notifying Landlord of Tenant's
         intention to do so affording Lessor ample opportunity to appear,
         intervene or otherwise appropriately assert and protect Landlord's
         interests with respect hereto.

         Tenant or the Premises relating to damage, contribution, cost recovery
         compensation, loss or injury resulting from or claimed to result from

         Materials on or removed from the Premises, including any complaints,
         notices, warnings, or asserted violations in connection therewith.
         Tenant shall also supply to Landlord as promptly as possible, and in no
         event later than five (5) business days after Tenant first receives or
         sends the same, copies of all claims, reports, complaints, notices,
         warnings or asserted violations relating in any way to the Premises of
         Tenant's use thereof. Tenant shall maintain copies of hazardous waste
         manifests reflecting the legal and proper disposal of all Hazardous
         Materials removed from the Premises and supply Landlord with copies of
         same on request.

         D. Indemnification. Tenant shall indemnify, defend and hold Landlord
         harmless from any and all damages, losses, expenses, liabilities,
         obligations, costs, etc., arising out of the handling or release of
         Hazardous Materials on the Premises, or the violation of any Hazardous
         Materials Laws by Tenant or any party subject to its control. Landlord
         shall indemnify, defend and hold Tenant harmless from any and all
         damages, losses, expenses, liabilities, obligations, costs, etc.,
         arising out of the handling or release of Hazardous Materials on the
         Premises or the violation of any Hazardous Materials Laws by Landlord
         or any party subject to its control (other than Tenant and any parties
         subject to Tenant's control). The foregoing indemnities shall survive
         the expiration or earlier termination of this Lease.

Re:   Property:     Rockwell International Facility at 5520 Harold Gatty Road,
                    Salt Lake City, Utah

      Lease Dated:  May 1, 1994 

      Landlord:     Rockwell International Corp.

From: Teltrust,Inc. ("Tenant")


      The undersigned Tenant is the lessee of approximately 30,000 square feet
of office space (the "Premises") located in the Property under the terms of a
lease (the "Lease") with Rockwell International Corp. ("Landlord"). Buyer is
about to purchase the Property. At Buyer's request, and knowing that Buyer will
rely upon the accuracy of the information contained herein in connection with
the purchase of the Property, the undersigned Tenant certifies to Buyer as
follows:

       1.    The Lease is dated May 1, 1994.

       2.    The commencement date of the Lease was May 1, 1994, and the
expiration date of the Lease term is November 30, 1996.

       3.    Rent:

             3.1    The fixed monthly rental payable under the Lease is
       $18,750.00 and has been paid through Sept. 1, 1994.
       
             3.2    All additional rent (including, as applicable, common area
       expenses, taxes, utilities, insurance, etc.) payable under the terms of
       the Lease has been paid through Sept. 1, 1994, and the Tenant is not
       presently contesting any amount or Tenant's share thereof.

             3.3    Tenant has paid all other taxes, charges, maintenance,
       insurance, utilities and other costs or expenses payable by Tenant under
       the terms and provisions of the Lease and no amounts remain unpaid as of
       the date hereof.

<PAGE>
 
         4.     The amount of security deposit being held by Landlord is
     $18,750.00. No interest is or will in the future become due or payable in
     connection with the security deposit.

         5.     The Lease is in full force and effect, and is binding and
     enforceable against Tenant in accordance with its terms.

         6.     The Lease constitutes the entire agreement between Landlord and
     Tenant with respect to the Premises and the Lease has not been amended,
     modified, supplemented, renewed or otherwise changed in any way, and there
     are no agreements or obligations between Tenant and Landlord, either oral
     or written, to so amend, renew, supplement, change or modify the terms or
     provisions of the Lease.

         7.     The Tenant has accepted the Premises and is in full and complete
     possession thereof.

         8.     The Tenant has not assigned, sublet, or encumbered its interest
     in the Lease.

         9.     Tenant has performed no alterations or works of improvement upon
     the Premises for which any contractor, workman or supplier is still unpaid
     or for which any mechanic or materialman may be entitled to file a lien
     against the Premises or the Property.

         10.    Tenant claims no offsets, rebates, concessions, abatements,
     "free rent" or defenses to the enforcement of the agreements, terms,
     covenants or conditions of the Lease. No rent under the Lease has been paid
     other than as is currently due, and there exists no credits or allowances
     to which Tenant is entitled.

         11.    To the best of knowledge of Tenant, neither the Landlord nor the
     Tenant is in default in the performance or observance of any of its
     obligations under the Lease, and no event has occurred and no conditions
     exist that, with the giving of notice or the passage of time, or both,
     would constitute a default under the terms of the Lease.

         12.    Tenant has no option to renew the Lease, or to lease any other
     space in, or to purchase all or part of, the Property, except as set forth
     in the Lease.

         13.    No action or proceeding instituted by Tenant against Landlord is
     pending in any court.

         14.    Tenant agrees to recognize Buyer as the Landlord under the Lease
     from and after the conveyance of the Property to Buyer.

         15.    Tenant has received no notice of prior sale, transfer,
     assignment, hypothecation or pledge of the Lease or of the rents provided
     therein.

the Premises. In the event the Premises shall be damaged to the extent for more
than 50% of the cost of replacement, or the building of which the Premises are a
part is damaged to the extent of 50% or more of the cost of replacement, Lessor
may elect either to repair or rebuild the Premises or the building or to
terminate this Lease upon giving notice of such election in writing to the
Lessee within Thirty (30) days after the happening of the event causing the
damage. If the Lessor fails to notify the Lessee that he will not repair, Lessor

portion of the Premises rendered untenable and all other rents shall continue as
provided in this Lease. Lessee shall continue the operation of Lessee's business

payments shall be withheld until such time as repairs are made and Lessee is
notified to again take possession of the Premises. Such notification to Lessee
shall be done in writing by the Lessor. If the Leased Premises cannot be
occupied for the intended use and business cannot be conducted due to partial
damage to the Leased Premises, the rents shall fully abate until Lessee is
notified by the Lessor to again take possession of the Premises. Lessee shall
not be entitled to and hereby waives all claims against Lessor for any
compensation or damage to and hereby waives all claims against Lessor for any
compensation or damage for loss of use of the whole or any part of the Premises

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

         13.0  CONSENT REQUIRED, LESSEE LIABLE: Lessee may not assign this Lease
and/or sublet the Premises other than to an affiliate, subsidiary, related or
parent company with the same use, or any part thereof, without in each instance
obtaining prior written consent from the Lessor, such permission shall not be
unreasonably withheld. Lessor may withhold his consent for assigning or
subletting to any sub-lessee or assignee which would be in violation of; the
restrictive covenants, exclusions, or other tenant Lease Agreements of the
Center, and the requirements heretofore agreed to with Lessee. Consent by the
Lessor to any assignment or subleasing shall not constitute waiver of the
necessity for such consent to any subsequent assignment or subletting.

         This prohibition against any assigning or subletting shall be construed
to include a prohibition against any assignment or subletting by operation of
law. If this Lease is assigned, or if the Premises or any part thereof or area
within be sublet or occupied by any person other than Lessee, Lessor may, if
Lessor elects, collect rent from the assignee, sublessee, or occupant and apply
the net amount collected to the rent herein reserved, but no such assignment,
subletting, occupancy or collection shall be deemed a waiver of this covenant,
or a release of Lessee from the further performance by Lessee of any covenants
or conditions herein contained. The Tenant will be released from the obligations
of this lease if the Sublessee has a net worth equal to or greater than the
Lessee, provided there is an adequate corporate guaranty for the performance of
the terms and conditions of this lease.

         14.0  LESSEE EVENTS OF DEFAULT AND LESSOR REMEDIES; LIEN: Lessor may
terminate the Lease and Term demised or terminate Lessee's right to possession
in the event Lessee makes assignment for the benefit of creditors; or writ of
execution or judgement is levied

                                       15

and not released in ten (10) days against days against leasehold estate or
Lessee's property; or if Lessee fails to pay any installment of any rents or any
other charge provided herein, or any portion thereof when the same shall be due
and payable and the same shall remain unpaid for a period of fifteen (15) days
after written notice from Lessor; or Lessee shall have failed to comply with any
other provisions of this Lease and shall not cure such failure within fifteen
(15) days after Lessor, by written notice, has informed Lessee of such
noncompliance (in case of a default which cannot, with diligence, be cured
within a period of Seven (7) days) Lessee shall have such additional time as
Lessor in writing shall extend to cure the same as may reasonably be necessary,
provided Lessee proceeds promptly and with due diligence to cure such default
after receiving said notice; or Lessee or its guarantor, if any, shall file in
any court a petition in bankruptcy or insolvency or for reorganization within
the meaning of Chapter X of the bankruptcy act or for arrangements within the
meaning of Chapter XI of said bankruptcy act, as amended, or for the appointment
of a Receiver of Trustee of all or a portion of Lessee's property; or an
involuntary petition if bankruptcy shall be filed against Lessee's property; or
an involuntary petition in bankruptcy shall be filed against Lessee or his
guarantor, if any, but Lessee may be reinstated if he is not otherwise in
default and such petition shall be vacated or withdrawn within ninety (90) days
after the date of filing thereof; or Lessee or its guarantor, if any, shall be
adjudicated a bankrupt or Lessee shall for reasons other than those
specifically permitted in this Lease, must cease to conduct his normal business
operations in the Premises or shall vacate or abandon the Premises and leave the
same vacated or abandoned for a period of three (3) days; or Lessee shall do or
permit to be done anything which creates a lien upon the Premises, provided,
however, that Lessee may contest the validity of such lien without being in
default hereunder by posting a bond equal to one and one-half (1 1/2) times the
amount of said lien.

        Upon any of the foregoing events Lessor may elect either;
              (1)   to cancel or terminate this Lease, or,
              (2)   to terminate Lessee's right to possession only without
                    terminating Lease, or,
              (3)   pursue any other remedy available by law or in equity.

In the event of election under (2) above to terminate Lessee's right to
possession only, Lessor may, at Lessor's option, enter into the Premises and
take and hold possession thereof without such entry into possession terminating
this Lease or releasing Lessee and holder in part from Lessee's

                                       16
<PAGE>
 
obligation to pay the rent hereunder for the full Term of this Lease. Upon such
re-entry, Lessor may remove all persons and property from the Premises and such
property may be removed and stored in a public warehouse or elsewhere at the
cost of and for the account of Lessee, all without service of notice or resort
to legal process or without being guilty of trespass, or becoming liable for any
loss or damage which may be occasioned thereby. Upon and after entry into
possession without termination of the Lease, Lessor shall use his best efforts
to relet the Premises, or any part thereof, for the account of the Lessee, to
any qualified parties.

         In the event that Lessor shall relet the Premises after retaking
possession of said Premises, the Lessor shall at his own discretion decide and
determine the rent terms and parties associated with such re-letting. In the
consideration collected by Lessor upon any such reletting for Lessee's account,
and after deducting all expenses incident thereto, including reasonable
brokerage fees, reasonable attorney's fees and court costs, shall not be
sufficient to pay monthly the full amount of the rents provided in this Lease,
Lessee shall pay Lessor the amount of each monthly deficiency upon demand. In
the event that Lessor shall have terminated Lessee's right to possession only,
Lessor shall have the right to cancel and terminate this Lease by serving five
(5) days written notice to Lessee of such further election and to pursue any
remedy at law or equity that may be available to the Lessor. Lessee specifically
agrees to be liable for all back rents and all future rents, including
additional rents, for the entire term of this Lease. A receiver may not operate
the Lessee's business or conduct sales on the Premises.

         14.1  DEFAULT REMEDIES, CUMULATIVE COSTS: All remedies expressed in
Article 14 and all other Articles of this Lease are cumulative, and a failure to
exercise one remedy or the exercise of one remedy shall not foreclose the
exercise of any other remedy. In the event it becomes necessary to begin to
enforce or encourage performance under this contract by involving an attorney,
the defaulting party shall be liable for all costs incurred, including
reasonable attorneys fees.

         14.2  LESSOR DEFAULT, NOTICE: Lessor shall in no event be charged with
default in the performance of any of its obligations hereunder unless and until
Lessor shall have failed to perform such obligations within thirty (30) days,
(or such additional time as is required to correct any such default) after
written notice by Lessee to Lessor properly specifying wherein Lessor has

                                       17
<PAGE>
 
failed to perform any such obligation.

         14.3  WAIVERS AND ACCEPTANCE OF PART PAYMENT BY EITHER PARTY: No waiver
by Lessor or Lessee of a breach of any agreement, obligation or condition of
this Lease shall be construed to be a waiver of any future breach of the same or
other covenants herein. No receipt of money by either party from the other,
after notice of default, after termination of this Lease, after commencement of
any suit, after final judgement, or after repossession of the Premises shall
reinstate, continue or extend the term of this Lease or effect any notice demand
or suit.

         RENEWAL, HOLDOVER, TENANCY, RENT, AND FIRST RIGHT OF REFUSAL
         ------------------------------------------------------------

         15.0 RENEWAL: Provided the Lessee is not in default and notifies Lessor
within six (6) months of the conclusion of the Term of this Lease, Lessee shall
have the option to renew this Lease for two separate five (5) year terms under
                                        --------------------------------
the same conditions expressed herein except that the basic and additional rents
for the renewal term shall be renegotiated with the Lessor. Should the Lessor
and Lessee fail to reach agreement on the basic and additional rents for any
such renewal term within four (4) months of expiration, a mutually agreed upon
Appraiser shall be employed with the cost to be split 50/50 to perform an
appraisal to determine the rents. Should the Lessor and Lessee fail to agree on
the appraised rents, a second mutually agreed upon Appraiser shall be employed
with the cost to be split 50/50 to perform a second appraisal. The rents shall
then be determined as the blended rate between the first and second appraisal.
Should the appraised base rental rate be 125% of the previous year's rate or
greater, the Lessee shall have the right to cancel the renewal notice with 60
days written notice to the Lessor. If renewal term rents have not been agreed
upon within thirty (30) days of the latter of the termination date of the Term
or the completion of the appraisal, Lessor may proceed with any actions it deems
pertinent to procure another Lessee for the Premises, and Lessor may elect
and/or pursue all of the remedies available to him by law, equity, or under this
Lease to evict the Lessee. After the expiration of the Term, if Lessee remains
in possession, Lessee shall be deemed to be a Lessee at will subject to all
covenants and & conditions of this lease, and rent shall accrue at 125% of the
previous year's rate. The Lessee shall have a on-going seven day first right of
refusal to lease any adjacent area in the

                                       18

building, should the existing occupant of any adjacent area vacate. The Lessee
shall exercise it's right to lease said area by notifying the Lessor in writing
within seven (7) days of receipt of Lessor's "Notice of Availability" of such
area(s). The terms and conditions of such expansion shall be consistent with the
terms and conditions of the initial lease should such expansion occur within
five (5) years of the initial commencement date. Thereafter, the terms and
conditions shall be consistent with the terms and conditions, including
concessions being offered in the market at that time.

        15.1  SURRENDER AT END OF TERM; HOLDOVER BY LESSEE: Lessee shall be
obligated to surrender the Premises at or before the conclusion of the Term of
this Lease. Premises shall be returned in a condition equal to or better than
those existing at the time the Term commenced, reasonable wear and tear
excepted. Lessee shall make all repairs occasioned by removal of Lessee's trade
fixtures, provided that Lessor has specifically waived continued ownership of
same as is provided in Article 12.

affirmatively assume Lessor's obligation under this covenant of quiet enjoyment,
as well as all other covenants to be performed by Lessor pursuant to the
provisions of this Lease.

        Lessee shall use the Premises during the full term of this Lease solely

        assistance services for other telecommunications companies; refund and
        repair services for independent pay telephone companies; independent

        Lessee covenants that during the entire term of this Lease it shall
        operate continuously in the premises the business above stated and will

        knowingly hire any employees who have previously been employed by TPUSA,

        efforts to implement hiring procedures designed to assure that no former
        employees of Teleperformance (i.e. persons employed by TPUSA, INC.
        within the previous three months) are hired by Lessee at the Premises.

                 SUBORDINATION, ATTORNMENT, AND NONDISTURBANCE
                                   AGREEMENT

        THIS AGREEMENT is made this 16th day of September, between  WASHINGTON
MUTUAL BANK (fsb), (a Washington corporation/federal savings bank) ("Lender"),
THE KIER CORPORATION, a UTAH CORPORATION ("Owner"), and Teltrust, Inc., a UTAH
CORPORATION ("Tenant").

        Owner is the land lord and Tenant is the tenant under that certain lease
dated February 26, 1997 (the "Lease"). The Lease demises portions (the "Leased
Premises") of the improvements located on certain real property in Davis County,
Utah, more particularly described in such Lease and on Exhibit A attached hereto
(the land and improvements are collectively referred to as the "Property").
Owner has obtained a commitment from Lender for financing for the Property
(the "Loan") to be evidenced by a promissory note (the "Note") in favor of
Lender, payment of which is to be secured by, among other things, a deed of
trust, security agreements, assignments of leases and rents and fixture filing
(the "Deed of Trust") on the Property, (and an assignment of leases and rents
made by Owner as assignor in favor of Lender as assignee (the "Assignment of
Rents", and collectively with the Deed of Trust, the "Security Documents").

        In order to induce Lender to make the Loan to Owner, and in order to
establish certain safeguards and priorities with respect to their respective
rights in connection with the Leased Premises, Lender has requested that Owner
obtain certain warranties and agreements from Tenant as hereinafter set forth.

        In consideration of the mutual benefits accruing to each, the receipt
and sufficiency of which is hereby acknowledged, the parties agree as
follows:

        1.     Restriction Against Modification.  The Lease  shall not be
               --------------------------------
modified, amended, terminated, or superseded, nor shall the Leased Premises be
sublet by Tenant, nor shall Tenant assign its rights under the Lease to a third
party, without the express prior written approval of Lender, which approval
shall not be unreasonably withheld.

        2.     Acknowledgment of Collateral Assignment. Tenant acknowledges that
               ---------------------------------------
the Lease will be collaterally assigned to Lender as security for the Loan and
that the terms of the collateral assignment will prohibit the collection of
rent more than one month in advance or the collection of a security deposit
exceeding two months rent. Upon written request by Lender accompanied by
Lender's written certification that an event of default has occurred under the
Note, or Security Documents, Tenant will commence paying

                                      -1-
<PAGE>
 
the rental and other amounts due and owing to Owner under the Lease directly
to Lender, and such payment to Lender shall constitute a full and complete
discharge of the obligations of Tenant to Owner under the Lease to the extent
of the amount(s) so paid.

        3.     Notice and Opportunity to Cure Defaults. Tenant agrees to notify
               ---------------------------------------
Lender of any breach or default by Owner under the Lease and offer Lender the
opportunity to cure such breach or default; and not to pursue any action or
exercise any legal right or remedy that Tenant may have to terminate the Lease
because of such breach of default for a period of thirty (30) days following
the later of: (I) expiration of the grace period, if any which Owner is given
to cure such default pursuant to the Lease or under applicable law; and (II) the
date upon which notice of such default was actually received by Lender. Tenant
further agrees that it will not exercise any right or remedy which it may have
to terminate the Lease because a breach or default which Lender had failed to
cure or cause to be cured within the aforementioned thirty (30) day period if
tile breach or default is one that can be cured, but cannot with due diligence 
by cured prior to the expiration of said thirty (30) day period, if Lender gives
notice of its intent to cure or cause such breach or default to be cured prior
to the expiration of said thirty (30) day period, and thereafter proceeds
promptly with and prosecutes with all due diligence the curing of such breach
or default.

               Nothing contained herein shall be construed as obligating Lender
to cure any breach or default or perform any obligation of Owner under the
Lease

               Notices which Lender is entitled to receive pursuit to this
Section 3 shall be delivered personally or by reputable overnight courier
service such as Federal Express to the address set forth below (or to such other
address or addresses as Lender may from time to time designate in writing):

                           Washington Mutual Bank (fsb)
                           1201 Third Avenue, WMT0710
                           1191 Second Avenue, SAS090
                           Seattle, Washington 98101
                           Attention:
                                     -------------------

        4.      Subordination.  The Lease is and at all times shall continue
                --------------
to be subject and subordinate to the Note and the lien of the Deed of Trust and
to all advances made or to be made thereunder, and to any renewals,
extensions, modifications, or replacements thereof.

        Specifically, and without limiting the generality of the foregoing,
Tenant agrees that with respect to: (I) any damage to or destruction of the
Property or any portion thereof by hazards insured against and for which
compensation is paid; payable or recoverable; or (II) any taking of the Property
or any portion thereof by partial or total condemnation (or a transfer in
lieu thereof); or (III) damages awarded for change of grade or loss of any use 
or enjoyment of the Property or any portion thereof, Tenant's claims thereto 
shall be subordinate to those of Lender under the Deed of Trust notwithstanding 
the covenants of Lender under Section 8 below.

        Tenant shall not subordinate the Lease to any lien., claim, mortgage,
deed of trust, or other encumbrance or any kind, except as provided in this
Section 4, and any such other subordination shall be deemed a default under 
the Lease and this Agreement.

                                      -2-
<PAGE>
 
        Until such time the Loan has been repaid in full and the Deed of Trust
fully reconveyed of record, any provisions of the Lease which purport to make
the Lease automatically subordinate to any other existing or future mortgage,
ground lease, deed of trust, or other encumbrance of any kind shall be of no
force or effect, and the Lease shall be deemed to have amended to delete such
provisions.

        5.      Attornment.  In the event of a foreclosure or sale of the
                ----------
Property pursuant to the trustee's power of sale, the Lease shall be recognized
as a direct lease from Lender, the purchaser at tile sheriff's or trustee's
sale, or any subsequent owner (collectively referred to as "Purchaser"), except
Purchaser shall not be liable for any previous act or omission of Owner under
the Lease; (II) subject to any offset which shall therefore have accrued to
Tenant against Owner; (III) subject to any obligation with respect to any
security deposit or prepaid rental for greater than one month under the Lease
unless such security deposit or prepaid rental has been physically delivered to
Purchaser; or (IV) bound by any previous modification of the Lease unless such
modification shall have been expressly approved in writing by Lender.

        The provisions of the immediately preceding paragraph shall be
equally applicable if Lender elects to accept from Owner a deed in lieu of
foreclosure.

        6.      Nondisturbance.  So long as no default exists, nor any event
                --------------
has continued to exist for such period of time (after notice, if any, required
by the Lease) as would entitle Owner under the Lease to terminate the Lease or
would cause, without any further action of Owner, the termination of the
Lease or would entitle Owner to dispossess Tenant thereunder, the Lease shall
not be terminated, nor shall Tenant's use, possession, or enjoyment of the
Leased Premises be interfered with, nor shall tile leasehold estate granted by
the Lease be affected in any foreclosure, or in any action or proceeding
instituted under or in connection with the Deed of Trust.

        7.      Hazardous Substances.  Tenant represents, warrants, covenants 
                --------------------
and agrees that any use or occupancy of the Property by Tenant is presently and
shall throughout the term of the Lease be in compliance with all state, federal
and local laws and regulations governing or in any way relating to the
generation, handling, treatment, storage, use, dumping, discharge or disposal of
any "Hazardous Substance" (as hereinafter defined); and that Tenant has not at
any time engaged in or permitted any material dumping, discharge or disposal of
such Hazardous Substances, at, on, in, above, under or about the Property.
Tenant agrees to indemnify, protect, defend and hold Lender harmless from any
claims, actions, proceedings, judgments, damages, penalties, fines, costs,
liabilities, losses and expenses of any kind that arise from any
misrepresentation or breach by Tenant of the representations, liabilities,
covenants and agreement contained in this Section 8. For purposes of this
Agreement, "Hazardous Substances" means any hazardous or toxic substances,
materials or wastes listed in tile United States Department of Transportation
Hazardous Materials Table (49 CFR 172.101) or by the Environmental Protection
Agency as hazardous substances (40 CFR Part 302) and amendments thereto, or now
or in the future defined in or regulated under any applicable local, state or
federal law, rule, regulation or ordinance.

        8.      Further Documents.  Owner and Tenant shall execute and deliver
                -----------------
to Lender or to any party to whom Tenant hereby agrees to attorn, in form and
substance satisfactory to Lender or such other party, such other instruments or
assurances as Lender or such other party shall request in order to more fully
carry out the intents and purposes of this Agreement.

                                      -3-
<PAGE>
 
         9.    Binding Effect.  This Agreement shall inure to the benefit of
               --------------
and be binding upon the parties hereto, their successors and assigns, and the
holder from time to time of the Note.

        10.    Modification.  This Agreement may not be modified other than by
               -------------
an agreement in writing, signed by the parties hereto or their respective
successors in interest.

        11.    Entire Agreement.  This Agreement constitutes the entire
               -----------------
agreement of the parties with respect to the subordination of the Lease to
the lien of the Deed of Trust. By its acceptance of Tenant's signature on
this Agreement, Lender has not agreed to any conditions to Tenant's agreement to
subordinate the Lease to a future mortgage or deed of trust which are contained
in the Lease itself and are not restated in this Agreement, including, but not
limited to, provisions which purport to obligate Lender for items with respect
to which Lender has been relieved of responsibility for pursuant to Section 5,
or provisions which purport to require Lender, as a condition to Tenant's
subordination, to make condemnation and insurance proceeds available to Owner
or Tenant and/or to apply such proceeds toward the cost of restoring or
repairing the Property.

        12.    Effect on Lease. Except as herein modified, all of the terms
               ----------------
and provisions of the Lease shall remain in full force and effect. In the event
of a conflict between the Lease and his Agreement, the terms and provisions of
this Agreement shall control.

        13.    Governing Law.  This Agreement shall be governed by and
               --------------
controlled in accordance with the laws of the state of Washington.

                                      -4-

                                 LEASE AGREEMENT


         THIS LEASE AGREEMENT, is made and entered into this 8th day of August,
1997, by and between PWK INVESTMENT, LLC, a Utah limited liability company, as
Lessor, and TELTRUST, INC., a Utah corporation, as Lessee.

         ARTICLE 1. PREMISES. Lessor is the owner, or shall become the owner, of
                    --------
real property situated at 401 North Eddie Rickenbacker Drive, Salt Lake City,
Salt Lake County, Utah 84116, and certain personal property located therein,
which real and personal property are described in Exhibits "A" and "B" attached
hereto. The real property described in Exhibit "A," the buildings and
improvements located thereon, and the personal property described in Exhibit
"B," are hereinafter referred to as the "Leased Property." "Leased Property"
shall also include all other buildings and improvements, and modifications and
additions thereto, hereafter located on the real property, to the extent such
improvements constitute the property of Lessor hereunder, and replacements of
the personal property.

         Lessor hereby leases to Lessee and Lessee hereby leases from Lessor the
Leased Property, which includes a building containing a total of approximately
26,266 square feet of floor space. The parties agree that this Lease is subject
to the effect of any covenants, conditions, restrictions, easements, mortgages
or deeds of trust, ground leases, rights of way and any other matters or
documents of record; the effect of any zoning laws of the city, county and state
where the Leased Property is situated, and general and special taxes not
delinquent. Lessee agrees that Lessee, and all persons in possession or holding
under Lessee, will conform to and will not violate the terms of any covenants,
conditions or restrictions of record which may now or hereafter encumber the
Leased Property (the "Restrictions"); and this Lease is subordinate to the
Restrictions and any amendments or modifications thereto.

         ARTICLE 2. PURPOSE. The Leased Property is to be used only for office
                    -------
and call center purposes, and for no other purpose without the prior written
consent of Lessor, which consent shall not be unreasonably withheld.

         ARTICLE 3. TERM; OPTION. The term of this Lease shall be for a period
                    ------------
of ten (10) consecutive full Lease Years, as the term Lease Year is hereinafter
defined, plus the fractional Lease Month, if any, from the "Commencement Date"
(as defined below) to the beginning of the first Lease Year ("Initial Term"),
plus any option periods exercised as provided below. The term "Lease Year" means
a period of twelve (12) full consecutive calendar months, beginning on the first
day of the calendar month coinciding with or immediately following the
Commencement Date.

         Provided that Lessee is not in default of any of the terms, covenants
and conditions of this Lease at the time the option provided herein is required
to be exercised; then Lessee shall have the right to extend the term of this
Lease for one (1) additional option term of five (5) years, upon the terms
herein stated.

                                        1
<PAGE>
 
         The option shall be exercised by Lessee giving Lessor written notice of
its intent to exercise the option at least 180 days prior to the expiration of
the Initial Term. If Lessee fails timely to exercise the option to extend, the
option shall be null and void and of no further force or effect. The option term
shall be governed by the same terms, covenants and conditions as the Initial
Term, with the exception of the length of the term, as referenced above, and the
rent. The minimum monthly rent during the option period shall be as set forth in
Article 5 below.

         ARTICLE 4. COMMENCEMENT DATE; LESSOR'S PURCHASE.  The
                    ------------------------------------
"Commencement Date" shall be the date Lessor delivers possession of the Leased
Property to Tenant. Lessor shall notify Tenant in writing at least fifteen (15)
days prior to the Commencement Date that the Leased Property is ready for
Lessee's work or occupancy. The effectiveness of this Lease is expressly
conditioned upon the closing of Lessor's purchase of the Leased Property on or
before September 15, 1997. Should Lessor fail to close the purchase of the
Leased Property on or before said date, or within such additional time as may be
agreed by Lessor and Lessee, then this Lease shall become null and void.

         ARTICLE 5. RENT. Lessee shall pay to Lessor, as Minimum Rent for the
                    ----
Leased Property during the term of this Lease, according to the schedule set
forth in Exhibit "C." Rent shall be paid in advance on or before the third day
of each calendar month during the term hereof. Minimum Rent for any partial
month shall be prorated on a per diem basis.

         Minimum Rent shall be abated for the first fourteen (14) months of the
Initial Term. Lessee shall, however, be obligated to pay Additional Rent and to
observe and perform all other covenants and conditions of this Lease during the
period Minimum Rent is abated.

         Rent shall be paid to Lessor without deduction or offset, in lawful
money of the United States of America and shall be paid to Lessor at 4449 South
Adonis Drive, Salt Lake City, Utah 84124, or to such other place as Lessor may
from time to time designate by written notice to Lessee. Any installment of
rent, other sum or any portion of such installment or other sum required under
this Lease to be paid by Lessee which has not been paid within eight (8) days
after the due date thereof (withstanding postal delays) shall, whether or not
demand therefor is made or notice of default is given, bear interest at the rate
of one and one half percent (1-1/2%) per month from the due date thereof until
paid in full. In addition thereto, Lessor may charge a sum equal to five percent

         ARTICLE 6. NET LEASE; ADDITIONAL RENT. Except as expressly provided in
                    --------------------------
this Lease, it is the intent of both parties that the Minimum Rent specified
herein shall be absolutely net to Lessor throughout each Lease Year of the term
of this Lease, and that all costs, expenses, and obligations of every kind
relating to the Leased Property, or the repair, replacement or maintenance of
the Leased Property, which may arise or become due during

                                        2
<PAGE>
 
the term hereof shall be paid by Lessee and that Lessor shall be indemnified by
Lessee against such costs, expenses, and obligations, except to the extent such
costs, expenses and obligations arise from Lessor's own fault or negligent
conduct. In addition to the other covenants and obligations set forth in this
Lease, Lessee specifically agrees to pay to Lessor, as Additional Rent, the
expenses and charges set forth below:

                  (i)    If the Leased Property is included in any P.U.D.,
                  condominium, or other form of development in which the owner
                  of the Leased Property is liable, under the Restrictions or
                  otherwise, for the payment of any taxes, costs, fees,
                  assessments, or similar expenses, then Lessee shall pay all
                  such costs and expenses.

                  (ii)   Lessee shall pay any and all Taxes (as defined below)
                  levied against the Leased Property for any period occurring
                  during the term of this Lease.

                  (iii)  Lessee shall pay the premiums for insurance required by
                  Article 16.

         "Taxes" shall mean and include all general and special taxes,
assessments, duties and levies, charged and levied upon or assessed by any
governmental authority against the Leased Property or any portion thereof, or
any leasehold improvements, fixtures, installations, additions, and equipment
whether owned by Lessor or Lessee. Taxes shall also include the reasonable cost
to Lessor in contesting the amount, validity, or the applicability of any Taxes
mentioned in this Article. Further included in the definition of Taxes herein
shall be general and special assessments, fees of every kind and nature,
commercial rental tax, levy, penalty or tax (other than inheritance or estate
taxes) imposed by any authority having the direct or indirect power to tax, as
against any legal or equitable interest of Lessor in the Leased Property or on
the act of entering into this Lease or as against Lessor's right to rent or
other income therefrom, or as against Lessor's business of leasing the Leased
Property, any tax, fee, or charge with respect to the possession, leasing,
transfer of interest, operation, management, maintenance, alteration, repair,
use, or occupancy by Lessee of the Leased Property, or any tax imposed in
substitution, partially or totally, for any tax previously included within the
definition of Taxes herein, or any additional tax, the nature of which may or
may not have been previously included within the definition of Taxes. Further,
if at any time during the term of this Lease the method of taxation or
assessment of real estate or the income therefrom prevailing at the time of
execution hereof shall be, or has been altered so as to cause the whole or any
part of the Taxes now or hereafter levied, assessed or imposed on real estate to
be levied, assessed or imposed upon Lessor, wholly or partially, as a capital
levy, business tax, permit or other charge, or on or measured by the rents
received therefrom, then such new or altered Taxes, regardless of their nature,
which are attributable to the Leased Property shall be deemed to be included
within the term "Taxes'.' for purposes of this Article 6, whether in
substitution for, or in addition to any other Taxes, save and except that such
shall not be deemed to include any enhancement of said tax attributable to other
income of Lessor. With respect to any general or special assessments which may
be levied upon or against the Leased

                                        3
<PAGE>
 
Property, or which may be evidenced by improvement or other bonds, or may be
paid in annual or semi-annual installments, only the amount of such installment,
pro rated for any partial year, and statutory interest, shall be included within
the computation of Taxes for which Lessee is responsible hereunder.

         During the term hereof Lessee shall pay prior to delinquency all taxes
assessed against and levied upon fixtures, furnishings, equipment and all other
personal property of Lessee and when possible Lessee shall cause said fixtures,
furnishings and equipment to be assessed and billed separately from the property
of Lessor. If any of Lessee's personal property shall be assessed with the
Leased Property, Lessee shall pay to Lessor or directly to the taxing authority,
the Taxes attributable to Lessee's personal property.

         Lessor shall estimate the Taxes, insurance, assessments, and common
area (and similar charges) required to be paid by Lessee hereunder for the
current calendar year (or other convenient period established by Lessor) or
portion thereof, and Lessee shall pay to Lessor at the same time each payment of
Minimum Rent is due, the amount of the estimate divided by the total number of
months included in the period covered by the estimate. Within three months after
the end of each calendar year (or other period), Lessor shall render a statement
to Lessee showing the difference between the Lessee's obligations for such
amounts and the amounts collected by Lessor from Lessee. Lessee shall pay any
shortage to Lessor within thirty (30) days after the date of such statement.
Correspondingly, Lessee shall receive a credit in the amount of any overpayment,
which credit may be applied by Lessee to subsequent payments due under this
Section, as long as Lessee is not in default for failure to pay under this
Lease. Lessee may audit Lessor's estimates and the expenses paid by Lessor, at
Lessee's expense. If the audit reveals that the amounts charged to Lessee for
actual expenses (as opposed to estimated expenses) exceeded actual expenses by
more than five percent (5%), then Lessor shall reimburse Lessee for the cost of
the audit. If the Lessee has overpaid such expenses at the end of the term of
the Lease, Lessor shall reimburse Lessee the amount of such overpayment.

         Lessee shall cause all bills, statements and other documents related to
Taxes, insurance, assessments, and common area (and similar charges) to be sent
directly to Lessor. The size of the monthly payments required by this Section to
be made by Lessee shall be adjusted from time to time as may be necessary in
light of the total taxes, assessments and insurance premiums to which such
payments are related.

         ARTICLE 7. USE OF LEASED PROPERTY. Lessee shall not use the Leased
                    ----------------------
Property or allow the Leased Property to be used for any improper, immoral, or
unlawful purpose, nor shall Lessee cause, maintain or permit any nuisance in, on
or about the Leased Property. Lessee shall not damage or deface or otherwise
commit or suffer to be committed any waste in, of or upon the Leased Property.

                                        4
<PAGE>
 
         ARTICLE 8. COMPLIANCE WITH LAW. Lessee shall not use the Leased
                    -------------------
Property or permit anything to be done in or about the Leased Property which
will in any way conflict with any law, statute, ordinance or government rule or
regulation now in force or which may hereafter be enacted or promulgated. Lessee
shall at its sole cost and expense promptly comply with all laws, statutes,
ordinances and governmental rules, regulations or requirements now in force or
which may hereafter be in force and with the requirements of any board of fire
underwriters or other similar body now or hereafter constituted related to or
affecting the condition, use or occupancy of the Leased Property, including
making such repairs, replacements, additions, or modifications to the Leased
Property as may be required (whether or not such are in the nature of capital
improvements). The judgment of any court of competent jurisdiction or the
admission of Lessee in an action against Lessee, whether Lessor be a party
thereto or not, that Lessee has violated any such law, statute, ordinance or
governmental rule, regulation or requirement, shall be conclusive of that fact
as between Lessor and Lessee.

         Lessee accepts the Leased Property subject to all applicable zoning,
municipal, county and state laws, ordinances, rules, regulations, orders,
restrictions of record, and requirements in effect during the term or any part
of the term hereof regulating the Leased Property.

         For purposes hereof, "Hazardous Materials" shall mean any and all
flammable explosives, radioactive material, hazardous waste, toxic substance or
related material, including but not limited to, those materials and substances
defined as "hazardous substances", "hazardous materials", "hazardous wastes" or
"toxic substances" in the Environmental Laws. For purposes hereof,
"Environmental Laws" shall mean all local, state and federal laws, statues,
rules and regulations, in force from time to time during the term of this Lease,
pertaining to Hazardous Materials and other environmental matters, including but
not limited to, the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, 42 U.S.C. Section 9601 et seq.; the Hazardous Materials
Transportation Act, 39 U.S.C. Section 1801, et seq.; the Solid Waste Disposal
Act, as amended by the Resource Conservation and Recovery Act, 42 U.S.C. Section
6901 et seq.; the Federal Clean Water Act 33 U.S.C. Section 1251 et seq.; the
Clean Air Act 42 U.S.C. Section 7401 et seq.; the Porter-Cologne Water Quality
Act, including all amendments thereto, replacements thereof, and regulations
adopted and publications promulgated pursuant thereto.

         Lessee agrees that, during the term of this Lease, Lessee shall not be
in violation of any federal, state or local law, ordinance or regulation then
applicable to the Leased Property and relating to industrial hygiene, soil,
water, or environmental conditions on, under or about the Leased Property
including, but not limited to, the Environmental Laws. Lessee further agrees
that during the term of this Lease, there shall be no use, presence, disposal,
storage, generation, release, or threatened release of Hazardous Materials on,
from or under the Leased Property. Lessee agrees to indemnify, defend, protect
and hold harmless Lessor, its directors, officers, employees, partners, and
agents from and against any and all losses, claims, demands, actions, damages
(whether direct or consequential), penalties, liabilities, costs and

                                        5
<PAGE>
 
expenses, including all reasonable attorney's fees and legal expenses, arising
out of any violation or alleged violation of any of the laws or regulations
referred to in this Article, or breach of any of the provisions of this Article.

         Lessor warrants that, as of the Commencement Date, the real property
shall be free of Hazardous Materials, and Lessor agrees to indemnify and defend
Lessee against any losses, claims, and damages with respect to any violation of
this covenant.

         The provisions of this Article shall survive the termination or
expiration of this Lease.

         ARTICLE 9. INITIAL TENANT IMPROVEMENTS; ALTERATIONS.     Lessee
                    ----------------------------------------
shall make the tenant improvements described in Exhibit "D" hereto and within
the time specified therein. Such tenant improvements shall be at Lessee's sole
cost and expense.

         Except as stated herein, Lessee shall not make or permit to be made any
other alterations, additions or improvements to or of the Leased Property or any
part thereof without the written consent of Lessor, which consent shall not be
unreasonably withheld, and any alterations, additions or improvements to, or on
the Leased Property, except movable furniture and trade fixtures, shall at once
become a part of the realty and belong to Lessor. Lessor's prior consent shall
not be required for minor alterations, additions or improvements that do not
affect the structure or roof of the buildings and that cost less than
$10,000.00. Lessee shall submit working drawings for any such alterations,
additions or improvements to Lessor for Lessor's prior written approval. In the
event Lessor consents to the making of any alterations, additions or
improvements to the Leased Property by Lessee, the same shall be made by Lessee
at Lessee's sole cost and expense and such work shall be performed in a
workmanlike manner.

         Lessee shall keep the Leased Property free from any liens arising out
of any work performed, materials furnished, or obligations incurred by Lessee.
In the event a mechanic's or other lien is filed against the Leased Property as
a result of a claim arising through the Lessee, Lessee shall, upon request by
Lessor, furnish to Lessor a surety bond satisfactory to Lessor in an amount
equal to at least one hundred fifty percent (150%) of the amount of the
contested lien, claim or demand, indemnifying Lessor against liability for the
same. Lessor may require Lessee to pay Lessor's reasonable attorneys' fees and
costs in participating in any action to foreclose such lien if Lessor shall
decide it is to its best interest to do so.

         Lessee shall return the Leased Property to Lessor at the expiration or
earlier termination of this Lease in good and sanitary order, condition and
repair, free of rubble and debris, broom clean, reasonable wear and tear
excepted. Any deferred maintenance or other conditions other than normal wear
and tear shall be remedied at Lessee's sole cost and expense. All damage to the
Leased Property caused by the removal of trade fixtures and other personal
property that Lessee is permitted to remove under the terms of this Lease and/or
such restoration shall be repaired by Lessee at its sole cost and expense prior
to termination.

                                        6
<PAGE>
 
         Lessee shall have the right to remove its personal property, including,
Lessee's switches, emergency power systems and generators, and
telecommunications equipment (but not including replacements of the personal
property being leased hereunder).

         ARTICLE 10. REPAIRS; MAINTENANCE; REPLACEMENT.     Lessor shall be 
                     ---------------------------------
responsible for the repair and maintenance of the roofs of buildings (both 
structure and membrane or covering) located on the Leased Property.

         Lessee shall, at all times during the term hereof and at Lessee's sole
cost and expense, keep, maintain and repair the remainder of the Leased Property
in good, working, and sanitary order and condition, including, without
limitation, replacement of all broken or damaged glass, replacement of light
globes or tubes and doors, window casements, heating and air conditioning
systems, plumbing, pipes, electrical wiring conduit, interior partitions,
fixtures, leasehold improvements and alterations, walls (both exterior and
interior), and all structural components, floor slab and subgrade and
foundations and footings, pavement, sidewalks, walls, fences, curbs, bumpers,
landscaping, irrigations systems, striping and line painting, sweeping, removal
of snow, ice, trash, garbage and other refuse. Lessee shall pay all fees,
required licenses and permits relating to the Leased Property.

         Lessor warrants that the HVAC system shall be in good working order on
the Commencement Date. On the Commencement Date, Lessor, Lessee, and an HVAC
professional mutually agreeable to the parties shall jointly inspect the HVAC
system, any deficiencies in the HVAC system then existing shall be noted in
writing, and Lessor shall cause any such deficiencies to be corrected promptly.
Except for such deficiencies noted in writing, the Lessee shall be deemed to
have accepted the HVAC system in good working order on the Commencement Date.

         Except as stated in this Lease, Lessee accepts the Leased Property in
its "as-is" condition. Lessee agrees on the last day of the term or sooner
termination of this Lease to surrender the Leased Property in good and sanitary
order, condition and repair, and in compliance with Lessee's obligations to
repair, replace and maintain the Leased Property as set forth in this Lease.

         Except as stated in this Lease, Lessee's obligations to repair and
maintain the Leased Property during the term hereof, and its obligations
respecting the condition of the Leased Property from time to time during the
term hereof and at the time the Leased Property are surrendered to Lessor, are
absolute and unconditional, and Lessee agrees that Lessor shall have no
obligation to repair, replace, or maintain the Leased Property regardless of the
existence of latent defects or circumstances now existing or hereafter arising.

         ARTICLE 11. WASTE AND NUISANCE. (a) Lessee covenants that it: 
                     ------------------
(i) will keep the Leased Property and every part thereof in a clean, reasonably
neat and orderly condition; (ii) will in all respects and at all times
fully comply with all health and policy regulations; (iii)

                                        7
<PAGE>
 
shall not overload the floors or permit or allow any waste, abuse, deterioration
or destructive use of the Leased Property to occur.

          (b) Lessee further covenants that it will (i) not cause or permit any
Hazardous Materials to be brought upon or used in or about the Leased Property;
(ii) immediately notify Lessor of any environmental concern raised by a private
party or governmental agency as it relates to the Leased Property; and (iii)
immediately notify Lessor of any Hazardous Material spill. In the event of a
violation hereof, Lessee shall immediately proceed, at Lessee's expense, to
remedy same. Failure of Lessee to commence clean up activities within five (5)
days after receipt of notice to so do shall be a default under this Lease.
Lessor shall, thereafter, have the right, but not the obligation, to remedy any
environmental violation upon the Leased Property and Lessee shall promptly
reimburse Lessor for all costs relating thereto. Lessor further retains the
right, in its sole, but reasonable discretion, to conduct any environmental
tests on the Leased Property should Lessor suspect a violation to exist upon the
Leased Property. Lessee shall and does agree to indemnify and hold Lessor
harmless from and against any and all damages, costs, expenses and liability
whatsoever, including, without limitation, attorneys' fees that Lessor may incur
because of Lessee's violation of, or the resulting enforcement of, any
Environmental Laws, which covenant shall survive the expiration or earlier
termination of this Lease.

     ARTICLE 12. ABANDONMENT. Lessee shall not, except in case of default by
                 -----------
Lessor, abandon the Leased Property at any time prior to the expiration or
earlier termination of the term hereof. In the event Lessee shall abandon or
surrender the Leased Property or be dispossessed by process of law or otherwise,
any personal property belonging to Lessee and left on the Leased Property beyond
thirty (30) days shall be deemed to have been abandoned.

     ARTICLE 13. ASSIGNMENT AND SUBLETTING. Lessee shall not assign this Lease 
                 -------------------------
or sublet the Leased Property or any part thereof to occupy or use the Leased
Property or any portion thereof without the prior written consent of Lessor,
which consent shall not be unreasonably withheld. Acceptance of rent by Lessor
of Lessee or Assignee shall not be deemed approval or acceptance of assignment
or subletting. Lessee shall remain liable for all terms and conditions of this
Lease at all times notwithstanding assignment or subletting; provided, however,
in the event of an assignment of the lease to an assignee that has a stated net
worth equal to or greater than Fifty Million Dollars ($50,000,000.00), as
established by current audited financial statements of such assignee, prepared
in accordance with generally accepted accounting principles, then Lessee shall
be released from liability hereunder from and after the effective date of such
assignment. In the event Lessor grants permission in writing for Lessee to
sublet or assign, Lessee shall pay to Lessor its reasonable costs and attorney's
fees incurred in reviewing the Lessee's request (not to exceed $300.00). Any
assignment or subletting by Lessee without Lessor's consent shall be a default
by Lessee hereunder. Lessee may assign, transfer or sublet the Leased Property
to an affiliate, subsidiary or parent company

                                        8
<PAGE>
 
of Lessee without the consent of Lessor; provided, however, that Lessee shall
remain fully liable hereunder.

         ARTICLE 14. PARKING AND LANDSCAPING. Lessee shall, at its sole cost,
                     -----------------------
maintain in good condition and repair all of the pavement, parking, striping and
line painting, exterior lights, irrigation systems, shrubs, grass and landscaped
areas on the Leased Property, and shall repair, maintain and/or replace the
pavement, parking area and landscaping as may be reasonably necessary to keep it
in good condition and repair, regardless of whether the nature of such repairs
may be in the nature of capital expenditures.

         ARTICLE 15. INDEMNIFICATION OF LESSOR. Lessee releases Lessor, and its
                     -------------------------
authorized representatives, from any claims for damage to any person, to the
Leased Property, or to the fixtures, personal property, Lessee's improvements
and alterations of either Lessor or Lessee, in or on the Leased Property,
including loss of income, that are caused by or result from risks insured or
required under the terms of this Lease to be insured against.

         Except as otherwise provided herein, Lessee, as a material part of the
consideration to be rendered to Lessor, shall indemnify, defend, protect and
hold harmless Lessor against all actions, claims, demands, damages, liabilities,
losses, penalties, or expenses of any kind which may be brought or imposed upon
Lessor or which Lessor may pay or incur by reason of injury to person or
property, from whatever cause, all or in any way connected with the condition or
use of the Leased Property on or after the Commencement Date, or the
improvements or personal property therein or thereon, including without
limitation any liability or injury to the person or property of Lessee, its
agents, officers, employees or invitees. Lessee agrees to indemnify, defend and
protect Lessor and hold it harmless from any and all liability, loss, cost or
obligation on account of, or arising out of, any such injury or loss however
occurring, including breach of the provisions of this Lease, and for any
conditions or occurrences arising prior to the date hereof. Nothing contained
herein shall obligate Lessee to indemnify Lessor against Lessor's active
negligence or willful acts, for which Lessor shall indemnify Lessee.

         In the event any action, suit or proceeding is brought against Lessor
by reason of such occurrence or condition, Lessee, upon Lessor's request will at
Lessee's expense resist and defend such action, suit or proceeding, or cause the
same to be resisted and defended by counsel designated either by Lessee or by
the insurer whose policy covers the occurrence and in either case approved by
Lessor. The obligations of Lessee under this Article arising by reason of any
occurrence taking place during the Lease term shall survive any termination of
this Lease.

         Lessee, as a material part of the consideration to be rendered to
Lessor, hereby waives all claims against Lessor for damages to goods, wares,
merchandise and loss of business in, upon or about the Leased Property and for
injury to Lessee, its agents, employees, invitees or third persons in or about
the Leased Property from any cause arising at any time, including

                                        9
<PAGE>
 
breach of the provisions of this Lease and the negligence of the parties hereto,
unless caused by the gross negligence or willful acts of Lessor.

         Wherever in this Article the term Lessor or Lessee is used and such
party is to receive the benefit of a provision contained in this Article, such
term shall refer not only to that party but also to its officers, directors,
employees, partners and agents.

         ARTICLE 16. INSURANCE. (a) Lessor, at the expense of Lessee as provided
                     ---------
herein, shall secure comprehensive general liability insurance on the Leased
Property on an occurrence basis with a minimum limit of liability in an amount
of One Million Dollars ($1,000,000.00) per occurrence, Two Million Dollars
($2,000,000.00) aggregate, or such other limits as Lessor may reasonably
determine. Lessor (and, at Lessor's option, the lender interested under any
mortgage or similar instrument then affecting the Leased Property) shall be
solely responsible for determining the amount of insurance and the specific
endorsements to be maintained.

         The foregoing requirement shall be satisfied, and Lessor shall not
purchase a separate liability policy, if and only for those time periods that
Lessee furnishes a prepaid insurance policy having coverage and limits equal to
or in excess of the above-specified policy, as such limits may be adjusted by
Lessor from time to time, and Lessee furnishes evidence of such to Lessor. Any
such policy shall not be cancelable except upon thirty (30) days' prior written
notice to Lessor. Lessor and any lender on the Leased Property shall be named
therein as additional insureds.

                  (b) Lessor, at the expense of Lessee as provided herein, shall
procure insurance coverage insuring Lessor against loss of, or damage to, all
buildings and structures on the Leased Property by reason of fire or any other
casualties. Such insurance shall be underwritten by a responsible insurance
company qualified to do business in the State where the Leased Property is
located, shall be in the face amount equal to the full replacement cost of all
buildings and structures on the Leased Property, and may include coverage for
loss of rents. Such insurance may cover loss or damage by fire, windstorm, hail,
acts of God, explosion, riot attending a strike, civil commotion, aircraft,
vehicles, smoke, and earthquake. Lessor (and, at Lessor's option, the lender
interested under any mortgage or similar instrument then affecting the Leased
Property) shall be solely responsible for determining the amount of fire and
extended coverage insurance and the specific endorsements to be maintained.
Lessor may also maintain boiler insurance on all heating boilers within the
Leased Property in such amounts as it determines. Lessor shall be named as an
insured on each such policy. The proceeds of such insurance in case of loss or
damage shall be paid to Lessor to be applied on account of the obligation of
Lessor to repair and/or rebuild the Premises as provided herein. Any proceeds
not required for such purpose shall be the sole property of Landlord. In any
event, Tenant shall have no interest in or claim to any such proceeds.

                  (c) Lessee agrees during the entire term hereof, to keep in
full force and effect a policy of comprehensive general liability insurance with
respect to the Leased Property, the

                                       10
<PAGE>
 
business operated by Lessee, and any subtenants, concessionaires, or licensees
of Lessee in the Leased Property, with minimum limits of not less than
$1,000,000 per occurrence, $2,000,000 in the aggregate. The policy shall name
Lessor, any person, firms, or corporations designated by Lessor, and Lessee as
insureds.

         At all times during the term hereof, Lessee shall keep in force at its
sole cost and expense, fire and extended coverage insurance, and against
sprinkler leakage or malfunction and water damage and against vandalism and
malicious mischief, on Lessee's trade fixtures, furnishings, equipment and other
personal property located or brought upon the Leased Property in full
replacement value thereof. Lessee shall also obtain broad form boiler and
machinery insurance on all air-conditioning equipment, boilers and other
pressure vessels or systems, whether fired or unfired, which are installed by
Lessee or which serve the Leased Property, except to the extent such items are
covered under insurance secured by Lessor. Such boiler and machinery insurance
shall cover the replacement value of such items. During the Lease term, the
proceeds from any such policy or policies of insurance shall be used for the
repair or replacement of the property so insured.

         The foregoing insurance required to be procured by Lessee shall be
issued by an insurance company approved by Lessor and a copy of the policy or a
certificate of insurance shall be delivered to Lessor.

                  (d) Each party shall cause each insurance policy obtained by
it to provide that the insurance company waives all rights of recovery by way of
subrogation against either party in connection with any damage covered by such
policy. Neither party shall be liable to the other for any damage caused by fire
or any other risks insured against under any property insurance policy carried
under the terms of this Lease.

                  (e) Any mortgage lender interested in any part of the Leased
Property may, at Lessor's option, be afforded coverage under any policy required
to be secured by Lessee hereunder, by use of a mortgagee's endorsement to the
policy concerned.

                  (f) No use shall be made or permitted to be made on the Leased
Property, nor acts done, which will increase the existing rate of insurance upon
the Leased Property or cause the cancellation of any insurance policy or any
part thereof as a result of such use or acts, nor shall Lessee sell, or permit
to be kept, used or sold, in or about the Leased Property, any article which
may be prohibited by the standard form of fire insurance policies. Lessee shall,
at its sole cost and expense, comply with any and all requirements pertaining to
the Leased Property, of any insurance organization or company, necessary for the
maintenance of reasonable property damage and public liability insurance,
covering the Leased Property.

         ARTICLE 17. UTILITIES; JANITORIAL SERVICE. (a) Lessee shall be solely
                     -----------------------------
responsible for, and shall promptly pay before delinquency, all charges for use
or consumption

                                       11
<PAGE>
 
of heat, sewer, water, gas, electricity, telephone or any other utility services
supplied to Lessee or to the Leased Property during the term hereof.

                (b)     Unless caused by Lessor's negligence or willful act,
Lessor shall not be liable in the event of any interruption in the supply of any
utility service to the Leased Property. Lessee agrees that it will not install
any equipment which will exceed or overload the capacity of any utility
facilities and that if any equipment installed by Lessee shall require
additional utility facilities, the same shall be installed at Lessee's expense
in accordance with plans and specifications first approved in writing by Lessor.

                (c)     Lessee shall provide at its sole expense regular
janitorial service for the Leased Property. In addition, Lessee shall provide an
adequate sized dumpster for the storage of refuse. Lessee shall arrange for the
removal of such refuse and periodic cleaning of such dumpster and the areas
immediately adjacent thereto.

          ARTICLE 18. ENTRY AND INSPECTION. Lessee shall permit Lessor and its
                      --------------------
agents to enter into and upon the Leased Property at all reasonable times and
upon twenty-four (24) hours advance notice for the purpose of inspecting the
same. During the six (6) months preceding the expiration of the term of this
Lease, Lessor may place usual and ordinary signs on the Leased Property
advertising the availability of the property for sale or lease. Lessor or its
agents may, during normal business hours, enter upon said Leased Property and
exhibit same to prospective lessees.

          ARTICLE 19. DEFAULT. In the event of any failure of Lessee to pay any
                      -------
rental or other sum due hereunder within eight (8) days after the same shall be
due, or any failure to perform any other of the terms, conditions or covenants
of this Lease to be observed or performed by Lessee for more than thirty (30)
days after written notice of such default shall have been given to Lessee (or,
if such failure cannot reasonably be cured within such thirty (30) days, if
Lessee fails to commence the cure within thirty (30) days or thereafter fails to
diligently prosecute such cure to completion), or if Lessee or any guarantor of
the Lease shall become bankrupt or insolvent or file any debtor proceedings or
take or have taken against Lessee or any guarantor of this Lease in any court
pursuant to any statute either of the United States or of any state a petition
in bankruptcy or insolvency or for reorganization or for the appointment of a
receiver or trustee of all or a portion of Lessee's or any such guarantor's
property, or if Lessee or any such guarantor makes an assignment for the benefit
of creditors or petitions for or enters into an arrangement, or if Lessee shall
abandon said Leased Property or suffer this Lease to be taken under any writ of
execution, Lessor, besides other rights or remedies it may have, shall have the
immediate right of re-entry and may remove all persons and property from the
Leased Property and such property may be removed and stored in a public
warehouse or elsewhere at the cost of and for the account of Lessee, all without
service of notice or resort to legal process and without being deemed guilty of
trespass or becoming liable, absent Lessor's negligence or willful misconduct,
for any loss or damage which may be occasioned thereby.

                                       12
<PAGE>
 
         Should Lessor elect to re-enter, as herein provided, or should it take
possession pursuant to legal proceedings or pursuant to any notice provided for
by law, it may either terminate this Lease or it may from time to time without
terminating this Lease, make such alterations and repairs as may be necessary in
order to relet the Leased Property and relet said Leased Property or any part
thereof for such term or terms (which may be for a term extending beyond the
term of this Lease) and at such rental or rentals and upon such other terms and
conditions as Lessor in its sole discretion may deem advisable, upon such
reletting, all rentals received by Lessor from such reletting shall be applied,
first, to the payment of any indebtedness other than rent due hereunder from
Lessee to Lessor, second, to the payment of any costs and expenses of such
alterations, repairs, and reletting (including commissions), third, to the
payment of rent due and unpaid hereunder, and the residue, if any, shall be held
by Lessor and applied toward payment of future rent as the same may become due
and payable hereunder. No such re-entry or taking possession of the Leased
Property by Lessor shall be construed as an election on its part to terminate
this Lease unless a written notice of such intention be given to Lessee or
unless the termination thereof be decreed by a court of competent jurisdiction.
Notwithstanding any such reletting without termination, in addition to any other
remedies it may have, it may recover from Lessee all damages it may incur by
reason of such breach, including the worth at the time of such termination of
the excess, if any, of the present value of the rent and charges equivalent to
rent reserved in this Lease for the remainder of the stated term (using a
discount rate of 10.0%) over the present value of the then reasonable rental
value of the Leased Property for the remainder of the stated term (using a
discount rate of 10.0%), all of which amounts shall be immediately due and
payable from Lessee to Lessor. To give effect to the remedies provided herein,
Lessee expressly waives the benefit of any statutory or common law that limits
or delays the Lessor's ability to recover damages for future rents and agrees
that such rents may be accelerated for purposes of determining Lessee's
liability and Lessor's damages.

         The remedies given to Lessor in this section shall be in addition and
supplemental to all other rights or remedies which Lessor may have under the
laws then in force.

         ARTICLE 20. DESTRUCTION. (a) If any building or structure on the Leased
                     -----------
Property shall be damaged or destroyed by fire or other casualty or cause,
Lessor shall repair such building or structure to a condition which is
substantially similar to the condition in existence prior to such casualty.

              (b) Notwithstanding the foregoing, however, if the building or
structure on the Leased Property is damaged to the extent of thirty-three and
one-third percent (33-1/3%) or more of its then replacement value, or if the
repair of the Leased Property would require more than one hundred twenty (120)
days, either party may terminate this Lease upon written notice given to the
other within thirty (30) days following such casualty or loss. If Lessee
determines, in its reasonable judgment, that its business on the Leased Property
cannot be carried on notwithstanding the repair or replacement of the Leased
Property, then Lessee shall

                                       13
<PAGE>
 
have the right to terminate this Lease upon written notice given to Lessor
within thirty (30) days following such casualty or loss.

               (c) Unless this Lease is terminated, Lessee shall, at its
expense, repair the fixtures and improvements installed by it within the Leased
Property and repair or replace any of Lessee's furniture, equipment or other
personal property damaged by such casualty or event.

               (d) If any building or structure on the Leased Property shall
be damaged or destroyed by fire or other casualty or cause, Minimum Rent shall
abate proportionately as to the portion of the Leased Property rendered
untenantable; but only upon the condition that insurance covers Lessor's loss of
rents for such period.

         ARTICLE 21. EMINENT DOMAIN. If all or more than 33-1/3% of the Leased
                     --------------
Property shall be taken or appropriated by any public or quasi-public authority
under the power of eminent domain, or transfer in lieu thereof, either party
hereto shall have the right, at its option, to terminate this Lease as of the
date title vests in the condemning entity. Lessor shall be entitled to any
award, or other payment made in connection with such condemnation. Lessee,
however, shall have the right to pursue a claim in any condemnation proceeding
against the condemning authority (but not against Lessor) for compensation for
any resulting damages to Lessee's business, trade fixtures and personal property
(but not for any diminution or loss of Lessee's leasehold estate). If a part of
the Leased Property shall be so taken or appropriated and this Lease is not
thereafter terminated, the rental thereafter to be paid shall be reduced in the
proportion that the area of the Leased Property so taken bears to the entire
Leased Property. Notwithstanding the foregoing, however, before Lessee may
terminate this Lease by reason of a taking or appropriation as described above,
such taking or appropriation shall be of such an extent and nature as to
substantially handicap, impede or impair Lessee's use of the Leased Property for
a period in excess of ninety (90) days.

         ARTICLE 22. MORTGAGE REQUIREMENTS. This Lease and all rights of Lessee
                     ---------------------
under this Lease are hereby subordinate hereunder to any lien of any mortgage or
mortgages or lien or other security interest resulting from any other method of
financing or refinancing, now or hereafter in force against the Leased Property.
The provisions of this Article notwithstanding, so long as Lessee is not in
default hereunder, this Lease shall remain in full force and effect for the full
term hereof and shall not be terminated as a result of any foreclosure or sale
or transfer in lieu of such proceedings pursuant to a mortgage or other
instrument to which Lessee has subordinated its rights pursuant hereto.

         In the event of the sale or assignment of Lessor's interest in the
Leased Property, or in the event of any proceeding brought for the foreclosure
of, or in the event of exercise of the power of sale under any mortgage or other
security instrument made by Lessor covering the Leased Property, Lessee shall
attorn to the assignee or purchaser and recognize such purchaser as Lessor under
this Lease.

                                       14
<PAGE>
 
         Lessee agrees to give any mortgagees (as defined below), by registered
mail, a copy of any notice of default served by Lessee upon Lessor, provided
that prior to such notice, Lessee has been notified, in writing (by way of a
Notice of Assignment of Rents and Leases or otherwise) of the addresses of any
such mortgagees. Lessee further agrees that if Lessor shall have failed to cure
such default within the time set forth in this Lease, then any such mortgagees
shall have an additional thirty (30) days within which to cure such default or
if such default cannot be cured within that time, then such additional time as
may be necessary, if within such thirty (30) days, any such mortgagee has
commenced and is diligently pursuing the remedies necessary to cure such default
(including but not limited to commencement of foreclosure proceedings, if
necessary to effect such cure), in which event this Lease shall not be
terminated. "Mortgagee" shall mean the holder of any mortgage, the beneficiary
under any deed of trust or the holder of any other security interest which
encumbers the Leased Property.

         ARTICLE 23. RULES REGULATIONS AND RESTRICTIVE COVENANTS.
                     --------------------------------------------
Lessee shall faithfully observe and comply with any rules, regulations and/or
restrictive covenants applicable to the Leased Property.

         ARTICLE 24. HOLDING OVER. If Lessee holds possession of the Leased
                     ------------
Property after the term of this Lease with Lessor's consent, and Lessor accepts
rent in the amounts hereinafter provided, Lessee shall become a lessee from
month-to-month upon terms equal to the then existing terms hereunder, except
that the Minimum Rent shall be the then existing Minimum Rent then payable
hereunder at the end of the term (on a monthly basis) multiplied by one hundred
twenty-five percent (125%). Minimum Rent and Additional Rent shall be paid in
advance on or before the third day of each month and Lessee shall continue in
possession until such tenancy shall be terminated by Lessor or until Lessee
shall have given to Lessor a written notice at least thirty (30) days prior to
the date of termination of such tenancy of its intention to terminate such
tenancy.

         ARTICLE 25. NOTICES. All notices and demands which may or are required
                     -------
to be given by either party to the other hereunder shall be sent by overnight
courier or United States certified or registered mail, postage prepaid,
addressed to:

         ARTICLE 26. LESSOR'S RIGHT TO CURE DEFAULTS. All covenants and
                     -------------------------------
agreements to be performed by Lessee under any of the terms of this Lease shall
be at its sole cost and expense and, except as otherwise specifically provided
herein, without any abatement of rent. If Lessee shall fail to pay any sum of
money, other than rent, required to be paid by it hereunder or shall fail to
perform any other act on its part to be performed hereunder, shall fail to cure
any such default within the applicable cure period, and such failure shall
continue for five (5) days after Lessee has received notice thereof by Lessor,
Lessor may, but shall not be obligated to do so, and without waiving any rights
of Lessor or releasing Lessee from any obligations of Lessee hereunder, make
such payment or perform such other act. All sums to be paid by Lessor and all
necessary incidental costs together with interest thereon at the rate of one and
one-half percent (1-1/2%) per month from the date of such payment by Lessor in
connection with the performance of any such act by Lessor shall be considered
additional rent hereunder and, except as otherwise in this Lease expressly
provided, shall be payable to Lessor on demand or, at the option of Lessor, in
such installments as Lessor may elect and may be added to any rent then due or
thereafter becoming due under this Lease.

         ARTICLE 27. FORCE MAJEURE. Lessor shall not be responsible or liable
                     -------------
for any delay in the observance or performance of any term or condition of this
Lease to be observed or performed by Lessor to the extent such delay results
from action of governmental authorities, civil commotions, strikes, fires, acts
of God, whether or not similar to the matters herein specifically enumerated and
any such delay shall extend by like time any period of performance by Lessor and
shall not be deemed a breach of or failure to perform this Lease or any
provision hereof.

         ARTICLE 28. TRANSFER OF LESSOR'S INTEREST. In the event Lessor
                     -----------------------------
transfers its interest in the Leased Property (other than a transfer for
security purposes), Lessor shall be relieved of all obligations accruing
hereunder after the effective date of such transfer, provided that such
obligations have been expressly assumed in writing by the transferee.

         ARTICLE 29. QUIET ENJOYMENT. Lessor covenants that so long as Lessee
                     ---------------
performs all of its obligations hereunder it shall peacefully and quietly have,
hold and enjoy the Leased Property for the term hereof.

         ARTICLE 30. SIGNS. Lessee shall have the right to use the monument sign
                     -----
located on the Leased Property. Lessee shall comply with all applicable
governmental regulations and other restrictions in the placement of signs or
advertisements on or in the Leased Property. The cost of installation and
regular maintenance of any signs shall be at the sole expense of Lessee. At the
termination of this Lease, or any extensions thereof, Lessee shall remove such
signs as are requested to be removed by Lessor, and alt damage caused by such
removal shall be repaired at Lessee's expense.

         ARTICLE 31. SURRENDER OF LEASE. The voluntary or other surrender of 
                     ------------------
this Lease by Lessee, or a mutual cancellation thereof, shall not work as a
merger, and shall, at the

                                       16
<PAGE>
 
option of Lessor, terminate all or any existing subleases or subtenancies, or
may, at the option of Lessor, operate as an assignment to it of any or all such
subleases or subtenancies.

         ARTICLE 32. LESSOR'S EXCULPATION. Anything in this Lease to the
                     --------------------
contrary notwithstanding, Lessee agrees that it shall look solely to the estate
and property of Lessor in the Leased Property for the collection of any judgment
(or other judicial process) requiring the payment of money by Lessor in the
event of any default or breach by Lessor with respect to any of the terms,
covenants, and conditions of this Lease to be observed and/or performed by
Lessor, and no other assets of Lessor shall be subject to levy, execution, or
other procedures for the satisfaction of Lessee's remedies.

         ARTICLE 33. ATTORNEYS' FEES. In any action or proceeding brought by
                     ---------------
either party to enforce or interpret this Lease or any provision hereof, the
prevailing party shall be entitled to recover its reasonable attorney fees and
costs incurred therein. Further, Lessee hereby agrees to pay, as additional
rent, all reasonable attorney's fees and disbursements, and all other court
costs or expenses of legal proceedings or other legal services which Lessor may
incur or pay out by reason of, or in connection with:

              (a) any appearance by Lessor (or any officer, partner, or
employee of Lessor) as a witness or otherwise in any action or proceeding
whatsoever involving or affecting Lessee or this Lease (provided, however, that
this clause shall not apply to actions between Lessor and Lessee, which are
governed by the first sentence of this Article);

              (b) subject to the provisions of Article 13 above, any
assignment, sublease, or leasehold mortgage proposed or granted by Lessee
(whether or not permitted under this Lease), and all negotiations with respect
thereto; and

              (c) any alteration of the Leased Property by Lessee or at the
request of Lessee, and all negotiations with respect thereto.

         Lessee's obligations under this Article shall survive the expiration or
any other termination of this Lease. This Article is intended to supplement (and
not to limit) other provisions of this Lease pertaining to indemnities and/or
attorney's fees.

         Should it be necessary for Lessor to employ legal counsel to enforce
any of the provisions of this Lease, Lessee agrees to pay, as additional rent,
all reasonable attorney's fees and court costs reasonably incurred thereby,
whether or not Lessor commences any legal action or proceeding.

         ARTICLE 34. ESTOPPEL CERTIFICATES AND FINANCING. Lessee agrees at any
                     -----------------------------------
time and from time to time upon not less than ten (10) days prior request by
Lessor, to execute, acknowledge and deliver to Lessor a written certificate in
recordable form certifying (if true), as of the date of such certificate: (1)
the beginning and termination dates hereof; (2)

                                       17
<PAGE>
 
that this Lease is in full force and effect and has not been assigned, modified,
supplemented or amended (except by such writings as shall be stated); (3)
stating that all conditions under this Lease to be performed by either party
have been satisfied (or stating which conditions remain unsatisfied); (4)
stating that there are no defenses or offsets against the enforcement of this
Lease by the Lessor, or stating those claimed by Lessee; (5) verifying the
amount of advance rental, if any paid by Lessee; (6) stating the date to which
rental has been paid; and (7) setting forth such other factual information
pertaining to the terms of the Lease as Lessor may reasonably request. Lessor,
Lessor's mortgage lenders and any purchasers of all or a portion of the Leased
Property shall be entitled to rely upon such certificate. Should Lessee fail
timely to comply with this Article, Lessor shall have the right to execute such
certificate as attorney in fact for Lessee and such certificate and the
representations contained therein shall be fully binding on Lessee as though
duly executed by Lessee.

         ARTICLE 35. SUCCESSORS AND ASSIGNS. The covenants and conditions herein
                     ----------------------
contained shall, subject to the provisions as to assignment, apply to and bind
the heirs successors, executors, administrators and assigns of all of the
parties hereto.

         ARTICLE 36. TIME. Time is of the essence of this Lease with respect to
                     ----
each and every Article, Section and Subsection hereof.

         ARTICLE 37. MISCELLANEOUS. Subject to any limitations on assignment set
                     -------------
forth herein, all of the terms and provisions of this Lease shall inure to the
benefit of and be binding upon the successors and assigns of each of the parties
hereto.

         The waiver by Lessor of any term, covenant or condition herein
contained shall not be deemed to be a waiver of the same or any other term,
covenant or condition or any subsequent breach of the same of any other term,
covenant or condition herein contained. The subsequent acceptance of rent
hereunder by Lessor shall not constitute a waiver of any preceding breach by
Lessee of any term, covenant or condition of this Lease, other than the failure
of Lessee to pay the particular rent so accepted, regardless of Lessor's
knowledge of such preceding breach at the time of acceptance of such rent.

         This Lease shall be governed by and construed in accordance with law of
Utah.

         The invalidity or enforceability of any provision hereof shall not
affect or impair any other provision hereof.

         The term "Lessor" as used herein shall include the agents, officers and
employees thereof. If there is more than one Lessee, the obligations of Lessee
hereunder shall be joint and several.

         Paragraph headings in this Lease are for convenience only and shall not
define or limit the scope or intent of any provision hereof.

         Lessee shall not record this Lease or a Memorandum thereof without the
written consent of Lessor. Lessor may file this Lease for record with the
Recorder of the County in which the Leased Property is located.

         Any consent required or permitted herein of Lessor or Lessee, as the
case may be, shall not be unreasonably withheld or delayed.

         ARTICLE 38. ENTIRE AGREEMENT. This Lease and the Exhibits and addenda
                     ----------------
if any, attached hereto constitute the entire agreement between the parties. All
Exhibits and addenda mentioned in this Lease are incorporated herein by
reference. No subsequent amendment to this Lease shall be binding upon Lessor or
Lessee unless reduced to writing and signed by the party to be charged
therewith. Submission of this Lease for examination does not constitute an
option for the Leased Property and becomes effective as a Lease only upon
execution and delivery thereof by Lessor to Lessee. If any provision contained
in an Exhibit or addendum is inconsistent with a provision in the body of this
Lease, the provision contained in said Exhibit addendum shall control. It is
hereby agreed that this Lease contains no restrictive covenants binding on other
lessees or exclusive use provisions in favor of Lessee. There are no
representations or promises by either party to the other except as are
specifically set forth herein. This Lease supersedes and revokes all previous
conversations, negotiations, arrangements, letters of intent, writings,
brochures, understandings, and information conveyed, whether oral or in writing,
between the parties hereto or their respective representatives or any agents of
any of them.

         ARTICLE 39. AUTHORITY OF SIGNATORIES. Each person executing this Lease
                     ------------------------
individually and personally represents and warrants that he is duly authorized
to execute and deliver the same on behalf of the entity for which he is signing
(whether it be a corporation, general or limited partnership or otherwise) and
that this Lease is binding upon said entity in accordance with its terms.

        (a)      Requested Registration. At any time after the earlier to occur
                 ----------------------
of (A) the fourth anniversary of the date hereof and (B) the Company's initial
public offering of equity securities, upon written request by the Holders of at
least twenty-five percent of the Registrable Securities outstanding at the time
of the request to the Company, that the Company effect the registration under
the Securities Act of all or part of the Registrable Securities (a "Requested
Registration"), the Company will use its best efforts to effect the registration
under the Securities Act of the Registrable Securities which the Company has
been so requested to register by the Holders within sixty (60) days after
receipt of such request or within thirty (30) days after receipt of such request
if the Company is qualified to file a registration statement on Commission Form
S-3 (or any successor or similar short-form registration statement
(collectively, "Commission Form S-3")); provided, however, that the Company
shall not be obligated to effect a Requested Registration, pursuant to this
subdivision (a) (X) unless either (i) the requesting Holders pay the
Registration Expenses pursuant to Section 2(d) hereof or (ii) the anticipated
aggregate offering price of the Registrable Securities to be sold is at least
$750,000, in the case of registration on Commission Form S-3, or at least
$5,000,000 in the case of other registrations or (Y) during the 180 day period
immediately following the commencement of the Company's public offering of
equity securities. The Company must effect an unlimited number of registrations
pursuant to this subdivision (a) to the extent such registrations may be
effected on Commission Form S-3, but the


                                      -2-
<PAGE>
 
Company shall not be obligated to effect more than three Requested Registrations
hereunder other than on Commission Form S-3. Subject to subdivision (f), the
Company may include in such Requested Registration other securities of the
Company for sale, for the Company's account or for the account of any other
person, if and to the extent that the managing underwriter determines that the
inclusion of such additional shares will not interfere with the orderly sale of
the underwritten securities at a price range acceptable to the Holders. Upon
receipt of a written request pursuant to this subdivision (a) the Company shall
promptly give written notice of such request to all Holders, and all Holders
shall be afforded the opportunity to participate in such request as follows: The
Company will be obligated to include in the Requested Registration such number
of Registrable Securities of any Holder joining in such request as are specified
in a written request by the Holder received by the Company within 20 days after
receipt of such written notice from the Company.

        (b)      Incidental Registration. If the Company for itself or any of
                 -----------------------
its security holders shall at any time or times after the date hereof determine
to register under the Securities Act any shares of its capital stock or other
securities (other than: (i) the registration of an offer, sale or other
disposition of securities solely to employees of; or other persons providing
services to, the Company, or any subsidiary pursuant to an employee or similar
benefit plan; or (ii) relating to a merger, acquisition or other transaction of
the type described in Rule 145 under the Securities Act or a comparable or
successor rule, registered on Form S-4 or similar or successor forms), on each
such occasion the Company will notify each Holder of such determination at
least thirty (30) days prior to the filing of such registration statement, and
upon the request of any Holder given in writing within twenty (20) days after
the receipt of such notice, the Company will use its best efforts as soon as
practicable thereafter to cause any of the Registrable Shares specified by any
such Holder to be included in such registration statement to the extent such
registration is permissible under the Securities Act and subject to the
conditions of the Securities Act (an "Incidental Registration").

        (c)      Registration Statement Form. The Company shall, if permitted
                 ---------------------------
by law, effect any registration requested under Section 2 by the filing of a
registration statement on Commission Form S-3 and shall use its best efforts to
take any action necessary to maintain its eligibility to utilize Commission Form
S-3 to permit resales as requested by the Holders with respect to Transactions
Involving Secondary Offerings as described in General Instruction I.B.3 of
Commission Form S-3.

        (d)      Expenses. The Company shall pay all Registration Expenses
                 --------
incurred in connection with any Incidental Registration, any Requested
Registrations that do not become effective and the first three Requested
Registrations that become effective pursuant to this Section 2. The requesting
Holders shall pay the Registration Expenses of any Requested Registrations after
the third Requested Registration.


        (e)      Effective Registration Statement. A Requested Registration or
                 --------------------------------
an Incidental Registration requested pursuant to Section 2(a) or Section 2(b),
respectively, shall not be deemed to have been effected unless it has become
effective with the Commission. Notwithstanding the


                                      -3-
<PAGE>
 
foregoing, a registration statement will not be deemed to have been effected if:
(i) after it has become effective with the Commission, such registration is
interfered with by any stop order, injunction, or other order or requirement of
the Commission or other governmental agency or any court proceeding for any
reason other than a misrepresentation or omission by any Holder; or (ii) the
conditions to closing specified in the purchase agreement or underwriting
agreement entered into in connection with such registration are not satisfied,
other than solely by reason of some act or omission by any Holder.

        (f)      Priority in Incidental Registration. If an Incidental
                 -----------------------------------
Registration is an underwritten registration initiated by the Company, and the
managing underwriters shall give written advice to the Company that, in their
opinion, market conditions dictate that no more than a specified maximum number
of securities (the "Underwriter's Maximum Number") could successfully be
included in such Incidental Registration, then: (i) the Company shall be
entitled to include in such registration that number of securities which the
Company proposes to offer and sell for its own account in such registration and
which does not exceed the Underwriter's Maximum Number; and (ii) the Company
will be obligated and required to include in such registration that number of
shares of Registrable Securities which shall have been requested by the Holders
thereof having registration rights hereunder or by holders having registration
rights pursuant to another registration rights agreement with the Company to be
included in such registration and which does not exceed the difference between
the Underwriter's Maximum Number and that number of securities which the Company
is entitled to include therein pursuant to clause (i) above and such number of
shares shall be allocated pro rata between the Holders and any other such
holders on the basis of the number of shares requested to be included therein by
the Holders, on the one hand, and such other holders, on the other hand.

        If less than all of the Registrable Securities requested to be included
in any such registration by the Holders can be so included due to these priority
requirements, then each requesting Holder's request shall be granted on an pro
rata basis with the other requesting Holders.

        (g)      Notwithstanding anything in paragraphs (a) and (b) of this
Section 2, the Company shall have the right to delay any registration of
Registrable Securities requested pursuant to paragraph (a) or (b) of this
Section 2 for up to ninety (90) days if such registration would, in the sole
reasonable judgment of the Company's Board of Directors, substantially interfere
with any material transaction being considered at the time of receipt of the
request from the Holders.

        3.       Registration Procedures.
                 -----------------------

        (a)      If and whenever the Company is required to use its best efforts
to effect the registration of any Registrable Securities under the Securities
Act as provided in Section 2, the Company, as expeditiously as possible and
subject to the terms and conditions of Section 2, will:

                (i) prepare and file with the Commission the requisite
registration statement to effect such registration and use its best efforts to
cause such registration to become and remain effective;

                                       -4-
<PAGE>
 
                (ii) permit any Holder which, in the reasonable judgment of the
Holder, might be deemed to be an underwriter or a controlling person of the
Company, to participate in the preparation of such registration statement and to
require the insertion therein of material, furnished to the Company in writing,
which in the reasonable judgment of such Holder and its counsel should be
included;

                (iii) prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and
to comply with the provisions of the Securities Act with respect to the
disposition of all securities covered by such registration statement until the
earlier of such time as all of such securities have been disposed of in
accordance with the intended methods of disposition by the seller or sellers
thereof set forth in such registration statement or the expiration of 180 days
after such registration statement becomes effective;

                (iv) furnish to the Holders such number of conformed copies of
such registration statement and of each such amendment and supplement thereto
(in each case including all exhibits), such number of copies of the prospectus
contained in such registration statement (including each preliminary prospectus
and any summary prospectus) and any other prospectus filed under Rule 424 under
the Securities Act, in conformity with the requirements of the Securities Act,
and such other documents, as the purchaser or any Holder of Registrable
Securities to be sold under such registration statement may reasonably request;

                (v) use its best efforts to register or qualify all Registrable
Securities covered by such registration statement under such other United States
state securities or blue sky laws of such jurisdictions as any Holder of
Registrable Securities to be sold under registration statement shall reasonably
request, to keep such registration or qualification in effect for so long as
such registration remains in effect, and take any other action which may be
reasonably necessary or advisable to enable the Holder of Registrable Securities
to be sold under such registration statement to consummate the disposition in
such jurisdictions of the securities owned by such Holder, except that the
Company shall not for any such purpose be required to (a) qualify generally to
do business as a foreign corporation in any jurisdiction wherein it would not
but for the requirements of this subdivision (v) be obligated to be so
qualified, or (b) subject itself to taxation in any such jurisdiction.

                (vi) use its best efforts to cause all Registrable Securities
covered by such registration statement to be registered with or approved by such
other United States state governmental agencies or authorities as may be
necessary to enable the Holder of Registrable Securities to be sold under such
registration statement to consummate the intended disposition of such
Registrable Securities;

                (vii) in the event of the issuance of any stop order suspending
the effectiveness of the registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Registrable Securities included in such

                                       -5-
<PAGE>
 
registration statement for sale in any jurisdiction, the Company shall use its
best efforts promptly to obtain the withdrawal of such order;

                (viii) use it best efforts to furnish to the Holders of
Registrable Securities to be sold under such registration statement (1) an
opinion, dated the effective date of the registration statement, of the
independent counsel representing the Company for the purposes of such
registration, addressed to the underwriters, if any, and to the Holders making
such request, stating that such registration statement has become effective
under the Securities Act and that (i) to the best knowledge of such counsel, no
stop order suspending the effectiveness thereof has been issued and no
proceedings for that purpose have been instituted or are pending or contemplated
under the Securities Act; (ii) the registration statement, the related
prospectus, and each amendment or supplement thereto, comply as to form in all
material respects with the requirements of the Securities Act and the applicable
rules and regulations of the Commission thereunder (except that such counsel
need express no opinion as to financial statements contained therein); (iii)
such counsel has no reason to believe that either the registration statement or
the prospectus, or any amendment or supplement thereto, contains any untrue
statement of a material fact or omits a material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading; (iv) the descriptions in the registration statement or the
prospectus, or any amendment or supplement thereto, of all legal and
governmental matters and contracts and other legal documents or instruments are
accurate and fairly present the information required to be shown; and (v) such
counsel does not know of any legal or governmental proceedings, pending or
contemplated, required to be described in the registration statement or
prospectus, or any amendment or supplement thereto, which are not described as
required nor of any contracts or documents or instruments of a character
required to be described in the registration statement or prospectus, or any
amendment or supplement thereto or to be filed as exhibits to the registration
statement which are not described and filed as required; and (2) a letter, dated
the effective date of the registration statement, from the independent certified
public accountants of the Company, addressed to the underwriters, if any, and to
the Holders making such request, stating that they are independent certified
public accountants within the meaning of the Securities Act and that in the
opinion of such accountants, the financial statements and other financial data
of the Company included in the registration statement or the prospectus, or any
amendment or supplement thereto, comply as to form in all material respects with
the applicable accounting requirements of the Securities Act.

                Such opinion of counsel shall additionally cover such legal
matters with respect to the registration in respect of which such opinion is
being given as the Holders may reasonably request. Such letter from the
independent certified public accountants shall additionally cover such other
financial matters (including information as to the period ending not more than
five business days prior to the date of such letter) with respect to the
registration in respect of which such letter is being given as the Holders may
reasonably request.

                (ix) immediately notify the Holders of Registrable Securities
included in such registration statement at any time when a prospectus relating
thereto is required to be delivered under the Securities Act, of the happening
of any event as result of which the prospectus included in such registration
statement, as then in effect, includes an untrue statement of material

                                       -6-
<PAGE>
 
fact or omits to state any material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the
circumstances under which they were made, and at the request of the Holders
promptly prepare and furnish to the Holders a reasonable number of copies of a
supplement to or an amendment of such prospectus as may be necessary so that, as
thereafter delivered to the purchasers of such securities, such prospectus shall
not include an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in the light of the circumstances under which they were made;

                (x) otherwise use its best efforts to comply with all applicable
rules and regulations of the Commission, and make available to its security
holders, as soon as reasonably practicable, an earnings statement covering the
period of at least twelve months, but not more than eighteen months, beginning
with the first full calendar month after the effective date of such registration
statement, which earnings statement shall satisfy the provisions of Section
11(a) of the Securities Act and Rule 158 thereunder, and not file any amendment
or supplement to such registration statement or prospectus to which any Holder
shall have reasonably objected in writing on the grounds that such amendment or
supplement does not comply in all material respects with the requirements of the
Securities Act or of the rules or regulations thereunder, having been furnished
with a copy thereof at least two business days prior to the filing thereof;

                (xi) provide a transfer agent for all Registrable Securities
covered by such registration statement not later than the effective date of such
registration statement; and

                (xii) use its best efforts to list all Registrable Securities
covered by such registration statement on any securities exchange on which any
of the Registrable Securities are then listed.

        (b)      The Company may require each Holder of Registrable Securities
to be sold under such registration statement, at the Company's expense, to
furnish the Company with such information and undertakings as it may reasonably
request regarding such Holder and the distribution of such securities as the
Company may from time to time reasonably request in writing.

        (c)      Each Holder, by execution of this Agreement, agrees (A) that
upon receipt of any notice of the Company of the happening of any event of the
kind described in subdivision (a)(ix) of this Section 3, such Holder will
forthwith discontinue its disposition of Registrable Securities pursuant to the
registration statement relating to such Registrable Securities until the receipt
by such Holder of the copies of the supplemented or amended prospectus
contemplated by subdivision (a)(ix) of this Section 3 and, if so directed by the
Company, will deliver to the Company all copies other than permanent file
copies, then in possession of the Holders of the prospectus relating to such
Registrable Securities current at the time of receipt of such notice and (B)
that it will immediately notify the Company, at any time when a prospectus
relating to the registration of such Registrable Securities is required to be
delivered under the Securities Act, of the happening of any event as a result of
which information previously furnished by such Holder to the Company for
inclusion in such prospectus contains an untrue statement of a material fact

                                      -7-
<PAGE>
 
or omits to state any material fact required to be stated therein or necessary
to make the statements therein not misleading in the light of the circumstances
under which they were made. In the event the Company or any such Holder shall
give any such notice, the period referred to in subdivision (a)(iii) of this
Section 3 shall be extended by a number of days equal to the number of days
during the period from and including the giving of notice pursuant to
subdivision (a)(ix) of this Section 3 to and including the date when such Holder
shall have received the copies of the supplemented or amended prospectus
contemplated by subdivision (a)(ix) of this Section 3.

        4.       Underwritten Offerings.
                 ----------------------

        (a)      Underwritten Offering. In connection with any underwritten
                 ---------------------
offering pursuant to a registration requested under Section 2(a), the Company
will enter into an underwriting agreement with the underwriters for such
offering, such agreement to be in form and substance reasonably satisfactory to
all Holders requesting such registration and such Holders' underwriters in their
reasonable judgment and to contain such representations and warranties by the
Company and such other terms as are customarily contained in agreements of that
type, including, without limitation, indemnities to the effect and to the extent
provided in Section 6. Each such Holder shall be a party to such underwriting
agreement and may, at its or their option, require that any or all of the
representations and warranties by, and the other agreements on the part of; the
Company to and for the benefit of such underwriters shall also be made to and
for the benefit of each such Holder and that any or all of the conditions
precedent to the obligations of such underwriters under such underwriting
agreement be conditions precedent to the obligations of each such Holder. No
Holder requesting such registration shall be required to make any
representations or warranties to or agreements with the Company or the
underwriters other than representations, warranties or agreements regarding such
Holder and its intended method of distribution and any other representation
required by law.

        (b)      Selection of Underwriters. If a Requested Registration pursuant
                 -------------------------
to Section 2(a) involves an underwritten offering, then the Company shall select
the underwriter from underwriting firms of national reputation, subject to the
approval of the Holders of a majority of the Registrable Securities to be
included in such registration.

        (c)      Holdback Agreements. Each Holder agrees, if so reasonably
                 -------------------
required by the managing underwriter in a registration pursuant to Section 2,
not to effect any public sale or distribution of Registrable Securities or sales
of such Registrable Securities pursuant to Rule 144 or Rule 144A under the
Securities Act, during the seven (7) days prior to and the 180 days after any
firm commitment underwritten registration pursuant to Section 2 has become
effective (except as part of such underwritten registration) or, if the managing
underwriter advises the Company that, in its opinion, no such public sale or
distribution should be effected for a period of not more than 180 days after
such underwritten registration in order to complete the sale and distribution of
securities included in such registration and the Company gives notice to such
effect to such Holders of such advice, each Holder shall not effect any public
sale or distribution of Registrable Securities or sales of such Registrable
Securities pursuant to Rule 144 or Rule 144A under the Securities Act during
such period after such underwritten registration, except as

                                      -8-
<PAGE>
 
part of such underwritten registration, whether or not such Holder participates
in such registration.

        5.       Preparation, Reasonable Investigation.
                 -------------------------------------

        In connection with the preparation and filing of each registration
statement under the Securities Act, the Company will give the Holders of
Registrable Securities to be sold under such registration statement, the
underwriters, if any, and their respective counsel and accountants, drafts and
final copies of such registration statement, each prospectus included therein or
filed with the Commission and each amendment thereof or supplement thereto, at
least 5 business days prior to the filing thereof with the Commission, and will
give each of them such access to its books and records and such opportunities to
discuss the business of the Company with its officers and the independent public
accountants who have certified its financial statements as shall be necessary,
in the opinion of such Holders and such underwriters' respective counsel, to
conduct a reasonable investigation within the meaning of the Securities Act.

        6.       Indemnification and Contribution.
                 --------------------------------

        (a)      Indemnification by the Company. In the event of any
                 ------------------------------
registration under the Securities Act pursuant to Section 2 of any Registrable
Securities covered by such registration, the Company will, and hereby does,
indemnify and hold harmless each Holder of Registrable Securities to be sold
under such registration statement, each such Holder's legal counsel, each other
person who participates as an underwriter in the offering or sale of such
securities (if so required by such underwriter as a condition to including the
Registrable Securities of the Holders in such registration) and each other
person, if any, who controls any such Holder or any such underwriter within the
meaning of the Securities Act (collectively, the "Indemnified Parties"), against
any losses, claims, damages or liabilities, joint or several, to which the
Holders or underwriter or controlling person may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions or proceedings, whether commenced or threatened, in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such securities were registered under the Securities Act, any
preliminary prospectus, final prospectus or summary prospectus contained therein
or any document incorporated therein by reference, or any amendment or
supplement thereto, or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or arise out of any violation by the Company of any rule
or regulation promulgated under the Securities Act or state securities law
applicable to the Company and relating to action or inaction required of the
Company in connection with any such registration, and the Company will reimburse
the Indemnified Parties for any legal or any other expenses reasonably incurred
by them in connection with investigating or defending any such loss, claim,
liability, action or proceeding; provided, however, that the Company shall not
                                 --------  -------
be liable to any Indemnified Party in any such case to the extent that any such
loss, claim, damage, liability (or action or proceeding in respect thereof) or
expense arises out of or is based upon any untrue statement or alleged untrue
statement or omission or alleged omission made in such registration statement,
any such preliminary prospectus, final prospectus, summary prospectus, amendment

                                      -9-
<PAGE>
 
or supplement in reliance upon and in conformity with written information
furnished to the Company by such Indemnified Party.

        (b)      Indemnification by the Holders. The Company may require, as a
                 ------------------------------
condition to including any Registrable Securities of any person or entity in any
registration statement filed pursuant to Section 2, that the Company shall have
received an undertaking reasonably satisfactory to it from such person or entity
to indemnify and hold harmless (in the same manner and to the same extent as set
forth in subdivision (a) of this Section 6) the Company, each director of the
Company, each officer of the Company and each other person, if any, who controls
the Company within the meaning of the Securities Act, with respect to any
statement or alleged statement in or omission or alleged omission from such
registration statement, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto, if; and
only if; such statement or alleged statement or omission or alleged omission was
made in reliance upon and in conformity with information furnished in writing to
the Company directly by such person or entity specifically for use therein;
provided, however, that the obligation of any Holder hereunder shall be limited
to an amount equal to the proceeds received by such Holder upon the sale of
Registrable Securities sold in the offering covered by such registration.

        (c)      Notices of Claims, etc. Promptly after receipt by an
                 ----------------------
Indemnified Party of notice of the commencement of any action or proceeding
involving a claim referred to in the preceding subdivisions of this Section 6,
such Indemnified Party will, if a claim in respect thereof is to be made against
a party required to provide indemnification (an "Indemnifying Party"), give
written notice to the latter of the commencement of such action, provided,
                                                                 --------
however, that the failure of any Indemnified Party to give notice as provided
- -------
herein shall not relieve the Indemnifying Party of its obligation under the
preceding subdivisions of this Section 6, except to the extent that the
Indemnifying Party is actually prejudiced by such failure to give notice. In
case any such action is brought against an Indemnified Party, unless in such
Indemnified Party's reasonable judgment a conflict of interest between such
Indemnified and indemnifying parties may exist in respect of such claim, the
Indemnifying Party shall be entitled to participate in and to assume the defense
thereof; jointly with any other Indemnifying Party similarly notified to the
extent that it may wish, with counsel reasonably satisfactory to such
Indemnified Party, and after notice from the Indemnifying Party to such
Indemnified Party of its election so to assume the defense thereof; the
Indemnifying Party shall not be liable to such Indemnified Party for any legal
or other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation. No Indemnifying
Party shall consent to entry of any judgment or enter into any settlement
without the consent of the Indemnified Party which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.


        (d)      Other Indemnification. Indemnification similar to that
                 ---------------------
specified in the preceding subdivisions of this Section 6 (with appropriate
modifications) shall be given by the Company and each Holder of Registrable
Securities included in any registration statement with respect to

                                      -10-
<PAGE>
 
any required registration or other qualification of securities under any Federal
or state law or regulation of any governmental authority, other than the
Securities Act.

        (e)      Indemnification Payment. The indemnification required by this
                 -----------------------
Section 6 shall be made by periodic payments of the amount thereof during the
course of the investigation or defense, as and when bills are received or
expense, loss, damage or liability is incurred.

        (f)      Survival of Obligations. The obligations of the Company and of
                 -----------------------
the Holders under this Section 6 shall survive the completion of any offering of
Registrable Securities under this Agreement.

        (g)      Contribution. If the indemnification provided for in this
                 ------------
Section 6 is unavailable or insufficient to hold harmless an Indemnified Party,
then each Indemnifying Party shall contribute to the amount paid or payable to
such Indemnified Party as a result of the losses, claims, damages or liabilities
referred to in this Section 6 an amount or additional amount, as the case may
be, in such proportion as is appropriate to reflect 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 which resulted in such
losses, claims, demands or liabilities as well as any other relevant equitable
considerations. The relative fault 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 Indemnifying Party or parties on the one hand or the
Indemnified Party on the other and the parties' relative, intent, knowledge,
access to information and opportunity to correct or prevent such untrue
statement or omission. The amount paid to an Indemnified Party as a result of
the losses, claims, damages or liabilities referred to in the first sentence of
this Section 6(g) shall be deemed to include any legal or other expenses
reasonably incurred by such Indemnified Party in connection with investigating
or defending any action or claim which is the subject of this Section 6. No
person guilty of fraudulent misrepresentation within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

        7.       Covenants Relating to Rule 144.
                 ------------------------------

        With a view to making available the benefits of certain rules and
regulations of the Commission which may at any time permit the sale of
securities of the Company to the public without registration after such time as
a public market exists for the Common Stock of the Company, the Company agrees:

                 (a)     to make and keep public information available, as those
terms are understood and defined in Rule 144 under the Securities Act, at all
times after the effective date of the first registration under the Securities
Act filed by the Company for an offering of its securities to the general
public;

                 (b)     to use its best efforts to then file with the
Commission in a timely manner all reports and other documents required of the
Company under the Securities Act and the

                                      -11-
<PAGE>
 
Exchange Act, as amended (at any time after it has become subject to such
reporting requirements); and

                (c)     so long as a Holder owns any Registrable Securities, to
furnish to the Holder forthwith upon request a written statement by the Company
as to its compliance with the reporting requirements of said Rule 144 (at any
time after 90 days after the effective date of the first registration statement
filed by the Company for an offering of its securities to the general public),
and of the Securities Act and the Exchange Act (at any time after it has become
subject to such reporting requirements) a copy of the most recent annual or
quarterly report of the Company, and such other reports and documents of the
Company as a Holder may reasonably request in availing itself of any rule or
regulation of the Commission allowing a Holder to sell any such securities
without registration.

        8.       Other Registration Rights.
                 -------------------------

        The Company shall not grant to any Person any registration rights more
favorable than or inconsistent with any of those contained herein, so long as
any of the registration rights under this Agreement remain in effect.

        9.       Miscellaneous.
                 -------------

        (a)      Specific Performance. The parties hereto acknowledge that there
                 --------------------
may be no adequate remedy at law if any party fails to perform any of its
obligations hereunder and that each party may be irreparably harmed by any such
failure, and accordingly agree that each party, in addition to any other remedy
to which it may be entitled at law or in equity, shall be entitled to compel
specific performance of the obligations of any other party under this Agreement
in accordance with the terms and conditions of this Agreement.

        (b)      Notices. All demands, requests, notices and other
                 -------

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

         (a) Requested Registration. Subject to Section 8(g), at any time after
             ----------------------
180 days following the Company's registered initial public offering of equity
securities, upon written request by the Holders of more than fifty percent of
the Registrable Securities outstanding at the time of the request to the Company
that the Company effect the registration under the Securities Act of all or part
of the Registrable Securities (a "Requested Registration"), the Company will use
its best efforts to effect the registration under the Securities Act of the
Registrable Securities which the Company has been so requested to register by
the Holders within sixty (60) days after receipt of such request; provided,
however, that the Company shall not be obligated to effect a Requested
Registration pursuant to this Section 2(a) (A) if such registration may not be
effected on Commission Form S-3 (or any successor or similar short-form
registration statement), or (B) during the 180 day period immediately following
the commencement of a public offering of the Company's equity securities. The
Company will not be required to effect more than one Requested Registration
under this Section 2(a) in any 12-month period. The Company may include in a
Requested Registration other securities of the Company for sale, for the
Company's account or for the account of any other person if and to the extent
the managing underwriter, if any, determines that the inclusion of such
additional shares will not interfere with the orderly sale of the underwritten
securities at a price range acceptable to the Holders. Upon receipt of a written
request pursuant to this subdivision (a) the Company shall promptly give written
notice of such request to all Holders, and all Holders shall be afforded the
opportunity to participate in such request as follows: The Company will be
obligated to include in the Requested Registration such number of Registrable
Securities of any Holder joining in such request as are specified in a written
request by the Holder received by the Company within 20 days after receipt of
such written notice from the Company.

         (b) Incidental Registration. If the Company for itself or any of its
             -----------------------
security holders shall at any time or times after the date hereof determine to
register under the Securities Act any shares of its capital stock or other
securities (other than: (i) the registration of an offer, sale or other
disposition of securities solely to employees of, or other persons
providing services to, the Company or any subsidiary pursuant to an employee or
similar benefit plan; or (ii) relating to a merger, acquisition or other
transaction of the type described in Rule 145 under the Securities Act or a
comparable or successor rule, registered on Form S-4 or similar or successor
forms), on each such occasion the Company will notify each Holder of such
determination at least thirty (30) days prior to the filing of such registration
statement, and upon the request of any Holder given in writing within twenty
(20) days after the receipt of such notice, the Company will use its best
efforts as soon as practicable thereafter to cause any of the Registrable
Securities specified by any such Holder to be included in such registration
statement to the extent such registration is permissible under the Securities
Act and subject to the conditions of the Securities Act (an "Incidental
Registration").

         (c) S-3 Eligibility. During any period in which the Holders may request
             ---------------
a Requested Registration pursuant to the provisions of Section 2(a), the Company
shall use its best efforts to take any action necessary to maintain its
eligibility to utilize Form S-3 to permit resales as requested by the Holders
with respect to Transactions Involving Secondary Offerings as described in
General Instruction I.B.3 of Commission Form S-3.

         (d) Expenses. The Company shall pay all Registration Expenses incurred
             --------
in connection with any Requested or Incidental Registrations, including any that
do not become effective.

<PAGE>
 
         (e) Effective Registration Statement. A Requested Registration or an
             --------------------------------
Incidental Registration requested pursuant to Section 2(a) or Section 2(b),
respectively, shall not be deemed to have been effected unless it has become
effective with the Commission. Notwithstanding the foregoing, a registration
statement will not be deemed to have been effected if: (i) after it has become
effective with the Commission, such registration is interfered with by any stop
order, injunction, or other order or requirement of the Commission or other
governmental agency or any court proceeding for any reason other than a
misrepresentation or omission by any Holder; or (ii) the conditions to closing
specified in the purchase agreement or underwriting agreement entered into in
connection with such registration are not satisfied, other than solely by reason
of some act or omission by any Holder.

         (f) Priority in Incidental Registration. If an Incidental Registration
             -----------------------------------
is an underwritten registration initiated by the Company, and the managing
underwriters shall give written advice to the Company that, in their opinion,
market conditions dictate that no more than a specified maximum number of
securities (the "Underwriter's Maximum Number") could successfully be included
in such Incidental Registration, then: (i) the Company shall be entitled to
include in such registration that number of securities which the Company
proposes to offer and sell for its own account in such registration and which
does not exceed the Underwriter's Maximum Number; and (ii) the Company will be
obligated and required to include in such registration that number of shares of
Registrable Securities which shall have been requested by the Holders thereof
having registration rights hereunder, by holders having registration rights
pursuant to another registration rights agreement with the Company or by Lyle
Keys to be included in such registration and which does not exceed the
difference between the Underwriter's Maximum Number and that number of
securities which the Company is entitled to include therein pursuant to clause
(i) above and such number of shares shall be allocated pro rata between the
                                                       --------
Holders, any other such holders, and Lyle Keys on the basis of the number of
shares requested to be included therein by the Holders, on the one hand, and
such other holders, and Lyle Keys on the other hand.

If less than all of the Registrable Securities requested to be included in any
such registration by the Holders can be so included due to these priority
requirements, then each requesting Holder's request shall be granted on an pro
rata basis with the other requesting Holders.

         (g) Notwithstanding anything in paragraphs (a) and (b) of this 
Section 2, the Company shall have the right to delay any registration of
Registrable Securities requested pursuant to paragraph (a) or (b) of this
Section 2 for up to 90 days if such registration would, in the sole reasonable
judgment of the Company's Board of Directors, substantially interfere with any
material transaction being considered at the time of receipt of the request from
the Holders.

3.  Registration Procedures.
    -----------------------

         (a) If and whenever the Company is required to use its best efforts to
effect the registration of any Registrable Securities under the Securities Act
as provided in Section 2, the Company, as expeditiously as possible and subject
to the terms and conditions of Section 2, will:

                  (i)   prepare and file with the Commission the requisite
registration statement to effect such registration and use its best efforts to
cause such registration to become and remain effective;

                  (ii)  with respect to a Requested Registration, permit any
Holder which, in the reasonable judgment of the Company, might be deemed to be

preparation of such registration statement and to require the insertion therein
of material furnished to the Company in writing, which in the reasonable
judgment of such Holder or its counsel should be included; provided, however,
the Company shall not be required to insert any material which in the reasonable
judgment of the Company's outside counsel includes an untrue statement of
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein not misleading in the light of the
circumstances under which they were made;

                  (v)    use its best efforts to register or qualify all

United States state securities or blue sky laws of such jurisdictions as any
Holder of Registrable Securities to be sold under such registration statement
shall reasonably request, to keep such registration or qualification in effect
for so long as such registration remains in effect, and take any other action
which may be reasonably necessary or advisable to enable the Holder of
Registrable Securities to be sold under such registration statement to
consummate the disposition in such jurisdictions of the securities owned by such
Holder, except that the Company shall not for any such purpose be required to
(a) qualify generally to do business as a foreign corporation in any
jurisdiction wherein it would not but for the requirements of this subdivision
(v) be obligated to be so qualified, or (b) subject itself to taxation in any
such jurisdiction.

                  (vi)   use its best efforts to cause all Registrable

Registrable Securities;

suspending the effectiveness of the registration statement, or of any order

promptly to obtain the withdrawal of such order;

underwriters and such selling Holder stating that such registration statement

of such counsel, no stop order suspending the effectiveness thereof has been
issued and no proceedings for that purpose have been instituted or are pending
or contemplated under the Securities Act, (B) the registration statement, the
related prospectus and each amendment or supplement thereof comply as to form in
all material respects with the requirements of the Securities Act (except that

counsel for the underwriters or the selling Holder; and (ii) a letter dated such
date from the independent public accountants retained by the Company, addressed
to the underwriters and to such selling Holder, stating that they are

circumstances under which they were made, and at the request of the Holders
promptly prepare and furnish to the Holders a reasonable number of copies of a
supplement to or an amendment of such prospectus as may be necessary so that, as

not include an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in the light of the circumstances under which they were made;

underwriters shall also be made to and for the benefit of each such Holder and
that any or all of the conditions precedent to the obligations of such
underwriters under such underwriting agreement be conditions precedent to the
obligations of each such Holder. No Holder requesting such registration shall be
required to make any representations or warranties to or agreements with the
Company or the underwriters other than representations, warranties or agreements
regarding such Holder, its Registrable Securities, its intended method of
distribution and any other representation required by law.

         (b) Selection of Underwriters. If a Requested Registration pursuant to
             -------------------------
Section 2(a) involves an underwritten offering, then the Company shall select
the underwriter from underwriting firms of national reputation, subject to the
approval of the Holders of a majority of the Registrable Securities to be
included in such registration.

         (c) Underwriter's Agreement. In the event of an underwritten offering
             -----------------------
pursuant to which the Holders request registration under Section 2, the sellers
of Registrable Securities to be distributed by such underwriters shall, as a
condition to inclusion of their Registrable Securities in such registration, be
parties to such underwriting agreement and shall be required to make such
representations or warranties as the underwriters may reasonably request,
including representations and warranties regarding such holder, such holder's
Registrable Securities and such holder's intended method of distribution and any
other representation required by law.

         (d) Holdback Agreements. Each Holder agrees, if so reasonably required
             ------------------- 
by the managing underwriter in a registration pursuant to Section 2, not to
effect any public sale or distribution of Registrable Securities or sales of
such Registrable Securities pursuant to Rule 144 or Rule 144A under the
Securities Act, during the seven (7) days prior to and the 180 days after any
firm commitment underwritten registration pursuant to Section 2 has become
effective (except as part of such underwritten registration), or if the managing
underwriter advises the Company that, in its opinion, no such public sale or
distribution should be effected for a period of not more than 180 days after
such public underwritten registration in order to complete the sale and
distribution of securities included in such registration and the Company gives
notice to such effect to such Holders of such advice, each Holder shall not
effect any public sale or distribution of Registrable Securities or sales of
such Registrable Securities pursuant to Rule 144 or Rule 144A under the
Securities Act during such period after such underwritten registration, except
as part of such underwritten registration, whether or not such Holder
participates in such registration.

5.  Preparation: Reasonable Investigation.
    -------------------------------------

         In connection with the preparation and filing of each registration
statement under the Securities Act, the Company will give the Holders of
Registrable Securities to be sold under such registration

                                        6
<PAGE>
 
statement, the underwriters, if any, and their respective counsel and
accountants, drafts and final copies of such registration statement, each
prospectus included therein or filed with the Commission and each amendment
thereof or supplement thereto, at least 5 business days prior to the filing
thereof with the Commission, and will give each of them such access to its books
and records and such opportunities to discuss the business of the Company with
its officers and the independent public accountants who have certified its
financial statements as shall be necessary, in the opinion of such Holders and
such underwriters' respective counsel, to conduct a reasonable investigation
within the meaning of the Securities Act.

6.  Indemnification and Contribution.
    --------------------------------

         (a) Indemnification of the Company. In the event of any registration
             ------------------------------
under the Securities Act pursuant to Section 2 of any Registrable Securities
covered by such registration, the Company will, and hereby does, indemnify and
hold harmless each Holder of Registrable Securities to be sold under such
registration statement, each such Holder's legal counsel, each other person who
participates as an underwriter in the offering or sale of such securities (if so
required by such underwriter as a condition to including the Registrable
Securities of the Holders in such registration) and each other person, if any,
who controls any such Holder or any such underwriter within the meaning of the
Securities Act (collectively, the "Indemnified Parties"), against any losses,
claims, damages or liabilities, joint or several, to which the Holders or
underwriter or controlling person may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions or
proceedings, whether commenced or threatened, in respect thereof) arise out of
or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any registration statement under which such
securities were registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus contained therein or any document
incorporated therein by reference, or any amendment or supplement thereto, or
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
arise out of any violation by the Company of any rule or regulation promulgated
under the Securities Act or state securities law applicable to the Company and
relating to action or inaction required of the Company in connection with any
such registration, and the Company will reimburse the Indemnified Parties for
any legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, liability, action or
proceeding; provided, however, that the Company shall not be liable to any
            --------  -------
Indemnified Party in any such case to the extent that any such loss, claim,
damage, liability (or action or proceeding in respect thereof) or expense arises
out of or is based upon any untrue statement or alleged untrue statement or
omission or alleged omission made in such registration statement, any such
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement in reliance upon and in conformity with written information
furnish to the Company by such Indemnified Party.

         (b) Indemnification by the Holders. The Company may require, as a
             ------------------------------
condition to including any Registrable Securities of any person or entity in any
registration statement filed pursuant to Section 2, that the Company shall have
received an undertaking reasonably satisfactory to it from such person or entity
to indemnify and hold harmless (in the same manner and to the same extent as set
forth in subdivision (a) of this Section 6) the Company, each director of the
Company, each officer of the Company and each other person, if any, who controls
the Company within the meaning of the Securities Act, with respect to any
statement or alleged statement in or omission or alleged omission from such
registration statement, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto, if, and
only if, such statement or alleged statement or omission or alleged omission was
made in reliance upon and in conformity with information furnished in writing
to the Company directly by such person or entity specifically for use therein;
provided, however, that the obligation of any Holder hereunder shall be limited
to an amount equal to the proceeds received by such Holder upon the sale of
Registrable Securities sold in the offering covered by such registration;
provided further, however, that the liability of such Holder shall not be
limited in the event that any loss or claim arises from the fraudulent
misrepresentations of the Holder.

         (c) Notices of Claims. Promptly after receipt by an Indemnified Party
             -----------------
of notice of the commencement of any action or proceeding involving a claim
referred to in the preceding subdivisions of this Section 6, such Indemnified
Party will, if a claim in respect thereof is to be made against a party required
to provide indemnification (an "Indemnifying Party"), give written notice to the
latter of the commencement of such action, provided, however that the failure of
any Indemnified Party to give notice as provided herein shall not relieve the
                                        -------- ------
Indemnifying Party of its obligation under the preceding subdivisions of this
Section 6, except to the extent that the Indemnifying Party is actually
prejudiced by such failure to give notice. In case any such action is brought
against an Indemnified Party, unless in such Indemnified Party's reasonable
judgement a conflict of interest between such Indemnified and indemnifying
parties may exist in respect of such claim, the Indemnifying Party shall be
entitled to participate in and to assume the defense thereof, jointly with any
other Indemnifying Party similarly notified to the extent that it may wish, with
counsel reasonably satisfactory to such Indemnified Party, and after notice from
the Indemnifying Party to such Indemnified Party of its election so to assume
the defense thereof, the Indemnifying Party shall not be liable to such
Indemnified Party for any legal or other expenses subsequently incurred by the
latter in connection with the defense thereof other then reasonable costs of
investigation. No Indemnifying Party shall consent to entry of any judgment or
enter into any settlement without the consent of the Indemnified Party which
does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party of a release from all liability in respect
to such claim or litigation.

         (d) Other Indemnification. Indemnification similar to that specified in
             ---------------------
the preceding subdivisions of this Section 6 (with appropriate modifications)
shall be given by the Company and each Holder of Registrable Securities included
in any registration statement with respect to any required registration or other
qualification of securities under any Federal or state law or regulation of any
governmental authority, other than the Securities Act.

         (e) Indemnification Payment. The indemnification required by this
             -----------------------
Section 6 shall be made by periodic payments of the amount thereof during the
course of the investigation or defense, as and when bills are received or
expense, loss, damage or liability is incurred.

         (f) Survival of Obligations. The obligations of the Company and of the
             -----------------------
Holders under this Section 6 shall survive the completion of any offering of
Registrable Securities under this Agreement.

         (g) Contribution. If the indemnification provided for in this Section 6
             ------------
is unavailable or insufficient to hold harmless an Indemnified Party, then each
Indemnifying Party shall contribute to the amount paid or payable to such
Indemnified Party as a result of the losses, claims, damages or liabilities
referred to in this Section 6 an amount or additional amount, as the case may
be, in such proportion as is appropriate to reflect 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 which resulted in such
losses, claims, demands or liabilities as well as any other relevant equitable
considerations. The relative fault 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 Indemnifying Party or parties on the one hand or the
Indemnified Party on the other and the parties' relative, intent, knowledge,
access to information and opportunity to correct or prevent such untrue
statement or omission. The amount paid to an Indemnified Party as a result of
the losses, claims, damages or liabilities referred to in the first sentence of
this Section 6(g) shall be deemed to include any legal or other expenses
reasonably incurred by such Indemnified Party in connection with investigating
or defending any action or claim which is the subject of this Section 6. No
person guilty of fraudulent misrepresentation within the meaning of Section
11(f) of the Securities Act shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

7.  Covenants Relating to Rule 144.
    ------------------------------

         With a view to making available the benefits of certain rules and
regulations of the Commission which may at any time permit the sale of
securities of the Company to the public without registration after such time as
a public market exists for the Common Stock of the Company' the Company agrees:

         (a) to make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, at all times after
the effective date of the first registration under the Securities Act filed by
the Company for an offering of its securities to the general public;

         (b)to use its best efforts to then file with the Commission in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act, as amended (at any time after it has become
subject to such reporting requirements); and

         (c) so long as a Holder owns any Registrable Securities, to furnish to
the Holder forthwith upon request a written statement by the Company as to its
compliance with the reporting requirements of said Rule 144 (at any time after
90 days after the effective date of the first registration statement filed by
the Company for an offering of its securities to the general public), and of the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements) a copy of the most recent annual or quarterly
report of the Company, and such other reports and documents of the Company as a
Holder may reasonably request in availing itself of any rule or regulation of
the Commission allowing a Holder to sell any such securities without
registration.

8.  Miscellaneous.
    -------------

         (a) Specific Performance. The parties hereto acknowledge that there may
             --------------------

specific performance of the obligations of any other party under this Agreement
in accordance with the terms and conditions of this Agreement.

             ------------
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.
