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

technical terms used in this Prospectus.
 
                                  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

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 the ninety-day period prior to his or her termination of employment
during each 182-day period during which such employee's noncompetition
agreement is in effect.

of dot.One. The Company has extended credit and currently sells services and
leases office space to dot.One. The Board of Directors of the Company has

dot.One.
 
  Pursuant to a Stock Redemption Agreement dated November 22, 1996 and

commission.
 
  On March 28, 1997 and May 12, 1997, the Company made two loans at interest
rates of 7% and 10%, respectively, in the principal amounts of $110,000 and
$93,552, respectively, to Jerry E. Romney, Jr., an officer of the Company.
Such loans are secured by 70,750 shares of Common Stock owned by Mr. Romney.
 
  During 1997, the Company loaned $80,400 to Jerry E. Romney, Jr. and $145,200
to Marc B. Cohen, each officers of the Company, to enable them to purchase
85,000 and 67,000 shares of Common Stock, respectively, upon the exercise of
vested stock options. The obligations of Messrs. Romney and Cohen to repay the
borrowed funds to the Company are evidenced by promissory notes that bear
interest at the prime interest rate and mature two years from date of issue.
The notes are secured by the underlying shares of Common Stock and other
assets of Messrs. Romney and Cohen.
 
  On April 9, 1997, the Board of Directors appointed Alan W. Saltzman to a

                         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.

                                   GLOSSARY
 
  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
 
                                     F-11
<PAGE>
 
                        TELTRUST, INC. AND SUBSIDIARIES
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
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

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.

   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
required to be set forth therein in relation to the basic financial statements
taken as a whole.

SECTION XII.  TERMINATION.

12.1  TERMINATION FOR CAUSE.  TELTRUST may terminate this Agreement with
reasonable notice to BSLD in the event BSLD is in default of its payment
obligations under this Agreement, provided that BSLD has failed to cure such 
non-payment within thirty (30) days of notification. BSLD may terminate this
Agreement at any time in the event TELTRUST is in breach of its performance
obligations under this Agreement, and provided TELTRUST fails to take all
commercially reasonable steps to cure such breach or default within sixty (60)
days after written notice of such default or breach is given to TELTRUST. In the
event BSLD terminates with cause pursuant to this SECTION 12.1, it shall be
relieved of its Term Commitment, per SECTION 10.2, and Minimum Live Operator
Charges, per SECTION 11.1 as of the date of termination of services. BSLD shall
not construe any potential negative effects on service levels due to exceeding
projections, as described in SECTION 11.1.2 as breach of TELTRUST performance
obligations.

12.2  TERMINATION PRIOR TO INITIAL MARKET ENTRY: BSLD may terminate this
Agreement at any time prior to Initial Market Entry in the event of an
indefinite legal or regulatory delay [***]. In the event of termination under
this SECTION 12.2, BSLD shall compensate TELTRUST for: a) all capital outlay, as
defined by generally accepted accounting principles, and; b) term contract
commitments made on BSLD's behalf (i.e. rental agreements) in connection with
TELTRUST's provisioning of operator and network services exclusively for BSLD as
contemplated in this Agreement.

In the event that BSLD has remitted "FARR" payments to TELTRUST in accordance
with SECTION 10.1.1 such "FARR" payments shall be credited toward the amount of
compensation to which TELTRUST is entitled under this SECTION 12.2. BSLD shall
incur no other liability or minimum payout to TELTRUST other than, if
applicable, what is described IN SECTIONS 10.1.1.(2), 11.1 and 11.2
respectively. Any amounts due TELTRUST shall be remitted in accordance with
SECTION 8.4.

12.3  TERMINATION WITHOUT CAUSE ON OR AFTER INITIAL MARKET ENTRY:  BSLD may
terminate this Agreement at any time on or after Initial Market Entry without
cause upon ninety (90) days prior written notice to TELTRUST and payment to
TELTRUST of the Early Termination Charge, as defined herein. BSLD acknowledges
and agrees that TELTRUST's willingness to provide equipment, switches, personnel
and the rates agreed to herein are based on BSLD's commitments outlined in
SECTION 10.2. It is difficult if not impossible to calculate TELTRUST's loss if
BSLD terminates the Agreement pursuant to this SECTION 12.3 prior to the end of
the term. [***]

SECTION XIII.  BRANDING AND REGULATORY ISSUES.

13.1  BRANDING AND CALL RATING.  To the extent that the services provided under
this Agreement are resold by BSLD or an Affiliate to an End User purchasing a
BellSouth service, TELRUST shall provide branding and call rating in accordance
with BSLD's federal and state tariffs, or in accordance with BSLD direction, in
which case BSLD warrants that any such direction would not be in conflict with
any local, state or federal regulation or law. Should BSLD seek to change or
alter its rating instructions, it shall inform TELTRUST of such changes in
writing and signed by BSLD's authorized representative. TELTRUST shall implement
such rating changes no later than two (2) business days from receipt of such
written notice, and shall confirm those changes in writing to BSLD within one
(1) business day of implementation.

13.2  EMERGENCY NUMBER DATA AND LIABILITY LIMITATION.  BSLD shall provide
TELTRUST with all applicable emergency number information. BSLD acknowledges and
agrees that TELTRUST shall not be liable to BSLD or any third party for any
special, indirect, incidental, punitive or consequential damages, including
without limitation, claims for damages by BSLD or its Affiliates or End Users
arising from TELTRUST emergency call handling procedures or the integrity of
BSLD's emergency database, or similar claims by a BSLD or Affiliate or End User,
absent TELTRUST's failure to follow the procedures required, as defined in
EXHIBIT XII, and absent such failure being the cause of the damage.

13.3  TARIFFS AND REGULATORY REQUIREMENTS.  BSLD represents that it (or one of
its Affiliates, as appropriate) has all necessary legal authority to charge and
collect the rates for services contemplated in this Agreement, and that BSLD (or
one of its Affiliates, as appropriate) complies with applicable regulatory
requirements incident to such rates. BSLD shall supply to TELTRUST, at its
request, copies of any applicable state and federal tariffs, certifications or
other documentation governing authority and rates, terms and conditions of BSLD
and Affiliates service provisioning.

SECTION XIV.  CONFIDENTIALITY AND NON-DISCLOSURE.

14.1  CONFIDENTIAL INFORMATION.

      14.1.1   Information furnished or disclosed by one Party or its agent or
      representative (the "Originating Party") to the other Party or its agent
      or representative (the "Receiving Party") in connection with or in
      contemplation of this Agreement, or relating to current or anticipated
      voice and data telecommunications needs of BSLD or its Participating
      Affiliates (including but not limited to proposals, contracts, tariff and
      contract drafts, specifications, drawings, network designs and design
      proposals, pricing information, strategic plans, computer programs,
      software and documentation, and other technical or business information
      related to current anticipated TELTRUST or BSLD products and services)
      shall be "Confidential Information".

      14.1.2   If such information is in written or other tangible form
      (including, without limitation, information incorporated in computer
      software or held in electronic storage media) when disclosed to the
      Receiving Party, it shall be Confidential Information only if it is
      identified by clear and conspicuous markings to be confidential and/or
      proprietary information of the Originating Party; provided, however, that
      all written proposals exchanged between the Parties regarding pricing of
      the Services shall be Confidential Information, whether or not expressly
      indicated by markings or statements to be confidential or proprietary.

      14.1.3   If such information is not in writing or other tangible form when
      disclosed to the Receiving Party, it shall be Confidential Information
      only if: (1) the original disclosure of the information is accompanied by
      a statement that the information is confidential or proprietary, or both;
      and (2) the Originating Party provides a written description of the
      information so disclosed, in detail reasonably sufficient to identify such
      information, to the Receiving Party within thirty (30) days after such
      original disclosure.

      14.1.4   The terms and conditions of this Agreement shall be deemed
      Confidential Information as to which each Party shall be both an
      Originating Party and a Receiving Party.

      14.1.5   Confidential Information shall be deemed the Property of the
      Originating Party.

      14.1.6   The following categories of information shall not be Confidential
      Information:

               (1)  Known to the Receiving Party without restriction when
               received, or thereafter developed independently by the Receiving
               Party; or

               (2)  Lawfully obtained from a source other than the Originating
               Party through no breach of confidence by the Receiving Party; or

               (3)  In the Public domain when received, or thereafter enters the
               public domain through no fault of the Receiving Party; or

               (4)  Disclosed by the Originating Party to a third party without
               restriction; or

               (5)  Lawfully in the possession of the Receiving Party at the
               time of receipt from the Originating Party.

      14.1.7   Rights and obligations provided in this Section shall take
      precedence over specific legends or statements associated with information
      when received.

14.2  PROTECTION OF CONFIDENTIALITY.   A Receiving Party  shall hold all
Confidential Information in confidence during the Term of this Agreement and for
a period of three (3) years following the end of the Term or such other period
as the Parties may agree. During that period, the Receiving Party:

      (a)  shall use such Confidential Information solely in furtherance of the
      matters contemplated by this Agreement and related to either Party's
      performance of this Agreement;

      (b)  shall reproduce such Confidential Information only to the extent
      necessary for such purposes;

      (c)  shall restrict disclosure of such Confidential Information to such of
      its employees or its Affiliate's employees as have a need to know such
      information for such purposes only;
 
      (d)  shall advise any employees and agents to whom such Confidential
      Information is disclosed of the obligations assumed in this Agreement;

      (e)  shall not disclose any Confidential Information to any third Party
      (not including disclosure to a BellSouth Subsidiary or persons identified
      in SECTIONS 14.3 AND 14.5) without prior written approval of the
      Originating Party except as expressly provided in this Agreement; and

      (f)  shall take such other reasonable measures as are necessary to prevent
      the disclosure, unauthorized use or publication of Confidential
      Information as a prudent business person would take to protect its own
      similar confidential information, including, at a minimum, the same
      measures it uses to prevent the disclosure, unauthorized use or
      publication or its own similar proprietary or confidential information.

14.3. DISCLOSURE TO OR BY AFFILIATES, CONSULTANTS OR SUBCONTRACTORS.  In the
absence of a contrary instruction by a Party, such Party's Affiliates,
consultants, subcontractors and agents performing work in connection with this
Agreement shall be deemed agents of such Party for purposes of receipt or
disclosure of Confidential Information. Accordingly, any receipt or disclosure
of Confidential Information by a Party's Affiliate, or its consultant or
subcontractor performing work in connection with this Agreement, shall be deemed
a receipt or disclosure by the Party.

14.4. RETURN OR DESTRUCTION OF CONFIDENTIAL INFORMATION.


      14.4.1   Upon termination of this Agreement, or at an earlier time if the
      information is no longer needed for the purposes described in SECTION
      14.2(A), each Party shall cease use of Confidential Information received
      from the other Party and shall use its best efforts to destroy all such
      Confidential Information, including copies thereof, then in its possession
      or control. Alternatively, or at the request of the Originating Party, the
      Receiving Party shall use its best efforts to return all such Confidential
      Information and copies to the Originating Party.

      14.4.2   Any Confidential Information that is contained in databases or
      mechanized systems in such a manner that it reasonably cannot be isolated
      for destruction or return, shall continue to be held in confidence subject
      to the provisions of this Agreement.

      14.4.3   The rights and obligations of the Parties under this Agreement
      with respect to any Confidential Information return to the Originating
      Party shall survive the return of the Confidential Information.

14.5  REQUIRED DISCLOSURE.  A Receiving Party may disclose Confidential
Information if such disclosure is in response to an order or request from a
court, the FCC or other regulatory body provided, however, that before making
such disclosure, the Receiving Party shall first give the Originating Party
reasonable notice and opportunity to object to the order or request, or obtain a
protective order covering the Confidential Information to be disclosed, or both.

SECTION XV.  INDEMNIFICATION AND LIMITATION OF LIABILITY.

15.1  INDEMNIFICATION.  Each Party (as "Indemnitor") shall indemnify, defend
and hold harmless the other Party (as "Indemnitee") from and against any and all
liabilities, costs, damages, fines, assessments, penalties and expenses
(including reasonable attorney's fees) resulting from (a) breach of any
provision in this Agreement by the lndemnitor, its employees or operators, or
(b) any misrepresentation or illegal act of Indemnitor, its employees or
operators, arising out of the Indemnitor's performance hereunder.

15.2  LIMITATION OF LIABILITY.  The liability of TELTRUST for damages resulting
in whole or in part from or arising in connection with the furnishing of service
under this Agreement, including but not limited to mistakes, omissions,
interruptions, delays, errors or other defects shall not exceed an amount equal
to the charges under this Agreement applicable to the specific call or service
that was affected. No other liability shall attach to TELTRUST including, but
not limited to, liability for special, indirect, or consequential damages
arising from or in connection with the furnishing of service or equipment
hereunder. This limitation shall not apply to instances of gross negligence or
willful misconduct on the part of TELTRUST.

15.3  WARRANTIES.  THE WARRANTIES AND REMEDIES SET FORTH IN THIS AGREEMENT ARE
THE ONLY WARRANTIES AND REMEDIES WITH RESPECT TO THE SERVICES PROVIDED
HEREUNDER, AND ARE IN LIEU OF ANY OTHER WARRANTY, WRITTEN OR ORAL, STATUTORY,
EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE.

SECTION XVI.  DISPUTE RESOLUTION.

16.1  MEDIATION.  In the event of material breach of any of the terms or
conditions of this Agreement, the wronged Party shall inform the other Party of
such breach in writing, which writing shall serve as notice to cure or rectify
such breach. The other Party shall have sixty (60) days from receipt of such
notice to cure or rectify such breach, except for non payment, as described in
SECTION 12.1. If, however, after sixty (60) days the wronged Party has not
received a satisfactory remedy, the Parties shall agree to submit all disputes
for mediation in accordance with the rules of the Center for Public Resources.
The mediation, unless otherwise mutually agreed upon by the Parties, shall be
conducted in Atlanta, GA for any dispute submitted by TELTRUST, or in Salt Lake
City, Utah for any dispute submitted by BSLD. The Parties shall use their best
efforts to conclude any mediation initiated hereunder within forty-five (45)
days, unless otherwise agreed to in writing by the Parties, from the initiation
of such mediation.

16.2  ARBITRATION.  If after the initial time period referred to in SECTION 16.1
above expires without resolution of the outstanding dispute, either Party may
request that the dispute be settled by binding arbitration in accordance with
the rules of the Center for Public Resources. The arbitration shall be governed
by the United States Arbitration Act, 9 U.S.C. Sec 1, et seq., and judgment upon
the award rendered by the arbitrator(s) may be entered by any court with

SECTION XVII.  TAXES

17.1  TAXES TO BE BILLED BY TELTRUST.

      17.1.1   For purposes of this Agreement, the term "Taxes" shall include
      but not be limited to Federal, State or local sales, use, excise, gross
      receipts or other taxes or tax-like fees (including tariff surcharges)
      imposed on or with respect to customer's services, excluding however, ad
      valorem property taxes, state and local privilege and license taxes based
      on gross revenue, taxes measured by net income, and any taxes or amounts
      in lieu of the foregoing excluded items.

      17.1.2   To the extent that TELTRUST's provision of services to BSLD is
      subject to any Taxes, TELTRUST shall calculate, bill, collect and remit
      such Taxes. TELTRUST shall collect such Taxes from BSLD in the same manner
      it collects such Taxes from other customers in the ordinary course of
      TELTRUST's business, but in no event prior to the time it invoices BSLD
      for the Services for which such Taxes are levied. TELTRUST shall calculate
      such Taxes for each TELTRUST service and not on the basis of the aggregate
      amount billed on each invoice.

      17.1.3   Should any Federal, State or local jurisdiction determine that
      Taxes are due as a result of TELTRUST's provision of Services, TELTRUST
      shall advise BSLD at least ten (10) days prior to the date by which a
      response, protest or other appeal must be filed, but in no event later
      than thirty (30) days after receipt of such assessment, proposed
      assessment or claim. If BSLD disagrees with the determination that any
      taxes are due by BSLD as a result of TELTRUST's provision of Services,
      BSLD shall, at its option and expense, have the right to seek a ruling as
      to the inapplicability of any such tax, to protest any assessment, to file
      and participate in any legal challenge to such assessment or determination
      or to file a claim for refund in its name or cause a claim for refund to
      be filed in TELTRUST's name. TELTRUST shall cooperate fully by providing
      records, testimony and such additional information or assistance as may
      reasonably be necessary. In the event that all or any portion of an amount
      sought to be collected or assessed must be paid in order to contest the
      imposition of any such Taxes or to avoid the existence of a lien on the
      assets of TELTRUST during the pendency of such contest, BSLD shall be
      responsible for such payment and shall be entitled to the benefit of any
      refund or recovery.

17.2  TAXES NOT TO BE BILLED BY TELTRUST.

      17.2.1   To the extent that TELTRUST's provision of Services to BSLD is
      exempt from Taxes in any jurisdiction, BSLD shall provide to TELTRUST for
      each such jurisdiction a valid tax exemption certificate or such other
      proof of tax-exempt status as may be required by the tax authorities in
      such jurisdiction. TELTRUST shall not bill BSLD for such Taxes.

<PAGE>
 
      17.2.2   BSLD or its Affiliates shall calculate, bill, collect and remit
      any Taxes (and any related interest and penalties) which may apply as a
      result of the provision of service by BSLD or its Affiliates to its
      customers. TELTRUST shall not include such taxes in the Call Detail
      Records furnished to BSLD.

      17.2.3   BSLD shall pay any tax for which it is responsible in connection
      with its receipt of TELTRUST Services that may be levied on or assessed
      against BSLD directly.

17.3  EFFORTS TO MINIMIZE TAXES.  TELTRUST shall cooperate reasonably with BSLD
to lawfully minimize any such taxes payable; such cooperation shall, if
requested, include changes in billing address or service reconfiguration,
subject to the terms of this Agreement governing such changes or
reconfigurations.

17.4  NEITHER PARTY LIABLE FOR OTHER'S INCOME TAXES.  Neither Party shall be
liable for taxes on the other Party's net income.

18.2  COMPLIANCE WITH APPLICABLE LAW.  This Agreement is made subject to all
present and future orders, rules and regulations of any regulatory body having
jurisdiction over the subject matter hereof, and to the laws of the United
States of America or any of its states having jurisdiction over the Parties and
the subject matter contained herein (collectively, "Applicable Law"). In the
event this Agreement or any of its provisions shall be found contrary to, or in
conflict with, any such Applicable Law, this Agreement shall be deemed modified
to the extent necessary to comply with such Applicable Law, and shall be
modified in such a way as the Parties mutually agree is consistent with the
form, intent, and purpose of its surviving provisions.

18.3  AUDIT RIGHTS.  BSLD shall have the right to perform audits as described
herein of the services provided to it by TELTRUST. The audit will be located at
a TELTRUST company location during normal business hours, and will be performed
only on information that reasonably may bear upon the provision of services
specified as part of this Agreement. Unless otherwise agreed, BSLD shall be
limited to one audit per calendar year. BSLD shall give notice of its intent to
perform an audit at least thirty (30) days prior to the proposed commencement
date. Such notice will include the specific objective of the audit, the proposed
commencement date, primary BSLD contact names, and to the best of BSLD's
ability, the information requested for review. TELTRUST will make reasonable
efforts to ensure that all information requested by BSLD and required to perform

information relating to other TELTRUST client or product activity, will be made
available by the audit commencement date. Within sixty (60) days after the
conclusion of an audit, BSLD will

<PAGE>
 
prepare a final written report, identifying any deficiencies found and
documenting any claims associated with the audit. Upon receipt of BSLD's final
report, TELTRUST will investigate all findings and claims, and provide a written
response to BSLD within thirty (30) days. Each Party will bear its own expenses
in connection with performing an audit.

18.4  GOVERNING LAW.  With respect to any lawsuit or binding arbitration
involving this Agreement, the Parties hereto agree that the prevailing law
shall be that of the State of Utah.

18.5  COSTS OF ENFORCEMENT.  In the event of litigation arising from the
enforcement of this Agreement the Parties hereto agree that all costs, including
reasonable attorney's fees of the prevailing Party shall be paid by the losing
Party, unless otherwise agreed.

18.6  NO AGENCY.  Neither Party is authorized to act as an agent for, or legal
representative of, the other Party and neither Party shall have authority to
assume or create any obligation on behalf of, in the name of, or binding upon,
the other Party. Provision of services hereunder shall not create a partnership,
joint venture or other like relationship between the Parties. BSLD, or a BSLD
Affiliate for which BSLD is acting as agent, is the service provider with
respect to End Users. TELTRUST is a supplier to BSLD and its Affiliates and has
no relationship to BSLD End Users.

18.7.  INTELLECTUAL PROPERTY.

  18.7.1  Neither BSLD or TELTRUST shall use the others trade names, trademarks
  or service marks ("Marks"), nor permit them to be displayed or used by third
  parties, except as specifically provided in this Agreement or upon other prior
  written approval of the other Party.  Nothing in this Agreement creates in a
  Party rights in the trade names, trademarks or service marks of the other
  Party.

  18.7.2  Except as otherwise specifically provided in this Agreement, neither
  BSLD nor TELTRUST will:  (a) use the other Party's corporate logos, trade
  dress, or other symbols that serve to identify and distinguish such other
  Party from its competitors (or use confusingly similar corporate logos, trade
  dress or such other symbols); or (b) conduct business under the other Party's
  corporate or trade names, logos, trademarks, service marks, trade dress, or
  other symbols that serve to identify and distinguish such other Party from its
  competitors (or under any confusingly similar corporate or trade names, logos,
  trademarks, service marks, trade dress or such other symbols).

18.8  WAIVER OF BREACH.  Failure of either Party to exercise any rights granted
to it hereunder upon any breach or default by such Party shall not be deemed a
waiver in the event of further breaches or defaults.

18.9  ASSIGNMENT.  Neither this Agreement nor any right or obligation hereunder
may be assigned or delegated to any other entity, except for subsidiaries or

                       TELTRUST DATABASE CONFLICT POLICY





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

                       TELTRUST DATABASE CONFLICT POLICY

A database conflict occurs in the event that a client submits an ANI for order 
entry, either by OSO (Operator Services Order) form or by file transfer, which 
already exists in the Teltrust Master Site Database under another client's 
account.

In order to resolve the conflict, Letters of Agency (LOAs) or other appropriate 
documentation (refer to the "Accepted Proof of Agency / Ownership" section 
below) is requested via fax.

Both clients involved receive a written notice of the database conflict listing 
the ANIs involved. Each client is given a twenty-four hour deadline to submit 
proper documentation to Teltrust via fax. The twenty-four hour deadline insures 
that Teltrust will provide a timely resolution to the database conflict.

If one client fails to submit the requested proof of ownership, the ANIs will, 
by default, be assigned to the other client's account. If both parties fail to 
provide proof of ownership, the ANI remains in the existing account.

ACCEPTED PROOF OF AGENCY / OWNERSHIP INCLUDES:

     LOA: 
     ----
     Teltrust requires that FCC LOA guidelines are met. Refer to the sample FCC 
     approved LOA attached.

     Phone Bill on a PAL (Public Access Line):
     -----------------------------------------

     The most recent bill available should be submitted. All associated ANIs
     must be indicated on the bill with the proper Billing Name and Address
     (BNA) listing the customer of record at the LEC level. The customer of
     record on the bill should be Teltrust's client.

     Contract or Notice of Acquisition:
     ----------------------------------
     
     All associated ANIs must be listed. The effective date of the agreement and
     signatures from both parties should be included. A contract or notice of
     acquisition only applies if one Teltrust client contracts with or sells
     phones to another Teltrust client.

In reviewing the documentation from each client, Teltrust will evaluate the
dates on each agreement and the ANIs listed on the document. The most recently
dated document will take priority. Teltrust will review signatures to insure
that the proper authority has been provided. Property managers and owners are
most commonly the authorized parties designated to choose long distance
providers / carriers. Teltrust reserves the right to contact the party whose
signature appears on the document to verify validity.

Both clients will receive a written notice of the database conflict resolution.

SECTION X.  TERM/EXCLUSIVITY

 10.1 CONTRACT TERM.  The Term of this Agreement shall begin on the Effective
 Date and shall remain in force for a period of three (3) years from the
 Effective Date. This Agreement shall automatically renew for quarterly periods
 subsequent to the expiration of the Initial Contract Term unless either Party
 notifies the other of its intent to terminate the Agreement with written notice
 no less than 120 days prior to the expiration of the Contract Term or any
 renewal period.

 10.2 EXCLUSIVITY.  BSPC shall select TELTRUST for interlata services described
 in this Agreement on an exclusive basis during the Contract Term, and any
 extensions thereof.  Exclusivity shall mean that at least ninety percent (90%)
 of BSPC's eligible pay stations will be PIC'd to TELTRUST.  Eligible pay
 stations are those pay telephones for which the Location Provider has

 the terms of this SECTION 10.2 except for those services specifically related
 to interLATA operator and network services as outlined in EXHIBIT I, "Rate

SECTION XI.  TERMINATION OF AGREEMENT.

 11.1  TERMINATION FOR CAUSE. Either Party may terminate this Agreement with
 reasonable notice to the other in the event that the Party to whom notice is
 given is in default of its payment obligations under this Agreement, provided
 that the defaulting Party has failed to cure such non payment within 30 days of
 notification. BSPC may terminate this Agreement at any time in the event
 TELTRUST is in breach of its performance obligations under this Agreement, and
 provided TELTRUST fails to take all commercially reasonable steps to cure such
 breach or default within sixty (60) days after written notice of such default
 or breach is given to TELTRUST. BSPC shall not construe any potential negative
 effects on service levels due to exceeding projections, as described in SECTION
 9.1.2 as breach of TELTRUST performance obligations.

 11.2  TERMINATION WITHOUT CAUSE. BSPC may terminate this Agreement at any time
 on or after the Effective Date without cause upon 90 days prior written notice
 to TELTRUST and payment to TELTRUST of the Early Termination Charge, as defined
 herein. BSPC acknowledges and agrees that TELTRUST's willingness to provide
 equipment, switches, personnel and the rates agreed to herein are based on
 BSPC's commitments contained in this Agreement. It is difficult if not
 impossible to calculate TELTRUST's loss if BSPC terminates the Agreement
 pursuant to this SECTION 11.2 prior to the end of the term. Therefore, to
 compensate TELTRUST for such loss, and not as a penalty, BSPC shall pay
 TELTRUST an Early Termination Charge in the event of such termination. The
 Early Termination Charge shall be [***]. This Early Termination Charge shall
 not apply in the event BSPC assigns its rights and obligations under this
 Agreement to an Affiliate in accordance with SECTION 17.9.

SECTION XII. BRANDING & REGULATORY ISSUES.

 12.1 BRANDING, CALL RATING, TARIFFS AND REGULATORY REQUIREMENTS. TELRUST shall
 provide branding and call rating in accordance with its  federal and state
 tariffs. TELTRUST represents that it has, or will have (North Carolina
 pending), all necessary legal authority to charge and collect the rates for
 services contemplated in this Agreement, and that TELTRUST will comply with any
 applicable state or federal regulatory requirements incident to such rates.
 BSPC and TELTRUST each represent that it will comply with all applicable local,
 state and federal regulations, including the Telephone Operator Consumer
 Services Improvement Act of 1990 ("TOCSIA"), or other applicable regulatory
 orders.  Both Parties understand that TELTRUST, as the operator service
 provider, is obligated to withhold amounts due BSPC for operator services calls
 if BSPC is not in compliance with regulations.

 12.2 EMERGENCY NUMBER DATA & LIABILITY LIMITATION. BSPC shall provide TELTRUST
 with all applicable emergency number information. BSPC acknowledges and agrees
 that TELTRUST shall not be liable to BSPC or any third party for any special,
 indirect, incidental, punitive or consequential damages, including without
 limitation, claims for damages by BSPC or End Users arising from TELTRUST
 emergency call handling procedures or the integrity of BSPC's emergency
 database, or similar claims by a BSPC End User, absent TELTRUST's negligence or
 failure to follow the procedures required, as defined in EXHIBIT XII, and
 absent such failure or negligence being the cause of the damage.

             (4) Disclosed by the Originating Party to a third party without
             restriction; or

             (5) Lawfully in the possession of the Receiving Party at the time

 13.2   PROTECTION OF CONFIDENTIALITY.   A Receiving Party shall hold all
 Confidential Information in confidence during the Term of this Agreement and
 for a period of three (3) years following the end of the Term or such other
 period as the Parties may agree. During that period, the Receiving Party:

        (a)  shall use such Confidential Information solely in furtherance of
        the matters contemplated by this Agreement and related to either Party's
        performance of this Agreement;

        (b)  shall reproduce such Confidential Information only to the extent
        necessary for such purposes;

        (c)  shall restrict disclosure of such Confidential Information to such
        of its employees or its Affiliate's employees as have a need to know
        such information for such purposes only;

        (d)  shall advise any employees to whom such Confidential Information is
        disclosed of the obligations assumed in this Agreement;

        (e)  shall not disclose any Confidential Information to any third Party

        identified in SECTIONS 13.3 AND 13.5) without prior written approval of
        the Originating Party except as expressly provided in this Agreement;
        and

        (f)  shall take such other reasonable measures as are necessary to
        prevent the disclosure, unauthorized use or publication of Confidential
        Information as a prudent business person would take to protect its own
        similar confidential information, including, at a minimum, the same
        measures it uses to prevent the disclosure, unauthorized use or
        publication or its own similar proprietary or confidential information.

 13.3.  DISCLOSURE TO OR BY AFFILIATES, CONSULTANTS OR SUBCONTRACTORS.  In the
 absence of a contrary instruction by a Party, such Party's Affiliates and its
 consultants and its subcontractors performing work in connection with this
 Agreement shall be deemed agents of such Party for purposes of receipt or
 disclosure of Confidential Information.  Accordingly, any receipt or disclosure
 of Confidential Information by a Party's Affiliate, or its consultant or
 subcontractor performing work in connection with this Agreement, shall be
 deemed a receipt or disclosure by the Party.

 13.4.  RETURN OR DESTRUCTION OF CONFIDENTIAL INFORMATION.

        information is no longer needed for the purposes described in SECTION
        13.2(A), each Party shall cease use of Confidential Information received
        from the other Party and shall use its best efforts to destroy all such
        Confidential Information, including copies thereof, then in its
        possession or control. Alternatively, or at the request of the
        Originating Party, the Receiving Party shall use its best efforts to
        return all such Confidential Information and copies to the Originating
        Party.

        13.4.2  Any Confidential Information that is contained in databases or
        mechanized systems in such a manner that it reasonably cannot be
        isolated for destruction or return, shall continue to be held in
        confidence subject to the provisions of this Agreement.

        13.4.3  The rights and obligations of the Parties under this Agreement
        with respect to any Confidential Information return to the Originating
        Party shall survive the return of the Confidential Information.

 Information if such disclosure is in response to an order or request from a
 court, the FCC or other regulatory body provided, however, that before making

                               SENT PAID CALLING

WHEREAS, BSPC and TELTRUST have entered into an Interlata Operator and Network
Services Agreement (the "Agreement"); and

WHEREAS,  TELTRUST wishes to provide Preferred Interexchange Carrier services
from certain BSPC pay telephone locations equipped with rating functionality,
including, in accordance with its applicable Sent Paid tariffed End User rates,
the network termination of direct dialed, coin sent calls; and

WHEREAS, BSPC maintains, services and collects coin from its pay telephones,
including those pay telephones that TELTRUST will provide Preferred
Interexchange Carrier Services to; and

WHEREAS, based on the specific mutual obligations and commitments as set forth
below, the Parties desire to enter into a business relationship in which BSPC
will collect, on behalf of TELTRUST, coins deposited for direct dialed interlata
calls by End Users, and remit the same to TELTRUST.

NOW, THEREFORE, in consideration of mutual covenants herein and other good and
valuable consideration, receipt of which is hereby acknowledged, the Parties
hereto agree as follows:

                       TELTRUST DATABASE CONFLICT POLiCY




________________________________________________________________________________
TELTRUST COMMUNICATIONS SERVICES, INC.                Proprietary & Confidential

                       TELTRUST DATABASE CONFLICT POLICY

A database conflict occurs in the event that a client submits an ANI for order
entry, either by OSO (Operator Services Order) form or by file transfer, which
already exists in the Teltrust Master Site Database under another client's
account.

In order to resolve the conflict, Letters of Agency (LOAs) or other appropriate
documentation (refer to the "Accepted Proof of Agency / Ownership" section
below) is requested via fax.

Both clients involved receive a written notice of the database conflict listing
the ANIs involved. Each client is given a twenty-four hour deadline to submit
proper documentation to Teltrust via fax. The twenty- four hour deadline insures
that Teltrust will provide a timely resolution to the database conflict.

If one client fails to submit the requested proof of ownership, the ANIs will,
by default, be assigned to the other client's account. If both parties fail to
provide proof of ownership, the ANI remains in the existing account.

Accepted Proof of Agency / Ownership includes:  

         LOA:
         --- 
         Teltrust requires that FCC LOA guidelines are met. Refer to the sample
         FCC approved LOA attached.

         Phone Bill on a PAL (Public Access Line):
         ---------------------------------------- 

         The most recent bill available should be submitted. All associated ANIs
         must be indicated on the bill with the proper Billing Name and Address
         (BNA) listing the customer of record at the LEC level. The customer of
         record on the bill should be Teltrust's client.

         Contract or Notice of Acquisition:
         --------------------------------- 

         All associated ANIs must be listed. The effective date of the agreement
         and signatures from both parties should be included. A contract or
         notice of acquisition only applies if one Teltrust client contracts
         with or sells phones to another Teltrust client.

In reviewing the documentation from each client, Teltrust will evaluate the
dates on each agreement and the ANIs listed on the document. The most recently
dated document will take priority. Teltrust will review signatures to insure
that the proper authority has been provided. Property managers and owners are
most commonly the authorized parties designated to choose long distance
providers / carriers. Teltrust reserves the right to contact the party whose
signature appears on the document to verify validity.

Both clients will receive a written notice of the database conflict resolution.

                        Agreement. TELTRUST agrees to keep confidential all
                        terms of BSLD's Fraud Management agreement in accordance

     procedures mutually established by Quest and Ameritech.

3.2  CUSTOM ORDER PROCESSING PROCEDURES.  Orders for the development of special
     or custom services not then specified in ADDENDUM A as being available to
     Ameritech shall be submitted by Ameritech to Quest in accordance with such
     special order processing procedures as the Parties shall mutually
     establish.  Each order for development of custom or special services shall

     completion or correction or attempt to process the order in the condition
     submitted by Ameritech.

     unless and until such order has been approved by Quest; provided that,

     provide Ameritech with notice of such rejection and the reason therefor.

                             BILLING AND COLLECTION
                             ----------------------

4.1  INVOICES AND PAYMENTS.

     (A)  Invoices.  Within ten (10) days of the last day of each calendar month
          --------                                                              
          during the term of this Agreement and for each month thereafter until
          all charges for the Wholesale Services other than Transmission
          Services have been billed and paid, Quest shall prepare and deliver to
          Ameritech an invoice summarizing the various non-Transmission Services
          charges incurred by Ameritech during the immediately preceding month.
          Quest shall on a weekly basis prepare and deliver to Ameritech an
          invoice summarizing the various Transmission Services charges incurred
          by Ameritech during the immediately preceding week.  Quest's failure
          to forward an invoice within the prescribed time period shall not
          relieve or otherwise modify or alter in any way Ameritech's obligation
          to make the payments required herein.

     (B)  Payments.  Ameritech shall pay the undisputed portion of each non-
          --------                                                         
          Transmission Services invoice no later than thirty (30) days after the
          invoice date.  Ameritech's payment shall be made by wire transfer to
          an account specified by Quest.  Ameritech shall pay the undisputed
          portion of each Transmission Services invoice not later than fifteen
          (15) days after the invoice date.  Ameritech's payment shall be made
          by wire transfer to a separate, specific bank account set up in
          Quest's name, but said account shall be subject to a restriction that
          payments into the account from Ameritech must be automatically
          forwarded by the bank to one (1) or more Carriers specified by
          Ameritech and Quest, and those forwarding instructions 

                                       4
<PAGE>
 
          cannot be altered or canceled without both Quest's and Ameritech's
          prior written consent. Any invoice that is not paid when due,
          including any disputed payment withheld by Ameritech pending
          resolution of the dispute with Quest which is subsequently determined
          to be due and owing to Quest, shall be subject to a late fee
          calculated using the prime rate (the average rate published in The
                                                                         ---
          Wall Street Journal on the payment due date) plus two percent (2%).
          -------------------

     (C)  Statements.  Within fifteen (15) days of the last day of each week
          ----------                                                        
          during the term of this Agreement and for each week thereafter until
          all settlements for the Retail Services have been paid, Ameritech
          shall prepare and deliver to Quest a statement summarizing the various
          revenue(s), calculated in accordance with the Rate Schedule, to be
          paid to Quest for providing the Retail Services during the immediately
          preceding month, less the Service Charges owed by Quest to Ameritech
          in connection therewith.  Ameritech shall include with each such
          statement the full net payment due and owing to Quest.

4.2  DISPUTES.  If either party disputes any calculation or amount shown on an
     invoice, it shall notify the other party of such dispute and the basis
     therefor within twenty (20) business days after receipt of such invoice.
     The non-disputing party shall respond to the disputing party in writing
     within ten (10) business days of its receipt of such a notice.  If the
     dispute is not resolved as a result of the response, Ameritech and Quest
     shall in good faith attempt to resolve such dispute through mediation and
     arbitration in accordance with ARTICLE XI hereof.

4.3  AUDIT.

     (A)  Upon reasonable advance written notice to Quest, Ameritech shall be
          entitled from time to time (but no more frequently than every six (6)
          months) to audit (a) Quest's books and records to confirm the accuracy
          of charges invoiced by Quest to Ameritech, (b) the End User database
          of information to verify its accuracy and completeness, and (c)
          Quest's personnel and methods and procedures to verify Quest's
          compliance with this Agreement.  Any such audit shall be performed at
          reasonably convenient times for the Parties and during normal business
          hours.  Any audit of the accuracy and completeness of Quest's invoices
          to Ameritech shall be limited to transactions underlying those
          invoices submitted within one (1) year of Ameritech's request for the
          audit.  If any audit conducted by Ameritech reveals a discrepancy of
          five percent (5%) or more, then Quest shall reimburse Ameritech's
          reasonable audit expenses.  Nothing herein shall give Ameritech the
          right to have access to any information other than that information
          related to Ameritech's account.

     (B)  Notwithstanding the foregoing, Ameritech shall be entitled to place
          one (1) or more of its employees and/or consultants at Quest's
          facilities in order to audit the accuracy, correctness and
          completeness of the Carrier's bills to Quest for Wholesale
          Transmission Services sold by Quest to Ameritech.  Quest shall furnish
          such employees/consultants reasonable accommodations, facilities and
          assistance in this effort, and Ameritech shall reimburse Quest for any
          reasonable out of pocket expenses (to include such expenses as
          telephone charges but not to include an allocation for rent, lights,
          heat, etc.) incurred by Quest in providing such accommodations,
          facilities and assistance.  If Quest requests and they have time,
          Ameritech will direct those employees/consultants to also audit the
          accuracy, correctness and completeness of the Carrier's bills to Quest
          for Retail Transmission Services provided by Quest to Ameritech's
          Customers and/or End Users, in which event Quest shall reimburse
          Ameritech for a pro rata portion of the employees'/consultants' time
          and expenses based on Ameritech's portion of the Carrier's bill in
          relation to Quest's portion of the Carrier's bill.

4.4  BILLING INQUIRIES AND COLLECTION EFFORTS.  Ameritech shall be solely
     responsible for responding to billing inquiries from its Customers and End
     Users, unless Ameritech has purchased that type of customer service from
     Quest.  Ameritech shall be solely responsible for all collection efforts
     involving its Customers, and the inability to collect payment from its
     Customers and End Users shall not affect Ameritech's obligation to make the
     payments to Quest required herein.

     shall pay or cause to be paid, when due, all federal, state and local taxes
     payable with respect to the revenues and profits recognized by that party
     hereunder.

5.2  COMPLIANCE WITH LAWS.  Each Party shall, at its own expense, comply with
     all federal, state, and local laws, ordinances and regulations relating to
     its duties, obligations, and performance under this Agreement and shall
     procure all certificates, permits, and licenses required in connection
     therewith.

5.3  TRADEMARKS.  Except for Ameritech's use of Quest's name and/or trademark(s)
     and logo(s) to identify that Quest is the provider of Retail Services to
     Ameritech's Customers and/or End Users, neither Party shall use the name or
     logo of the other Party or an Affiliate of the other Party without the
     prior express written consent of the other Party.  All use by a Party of
     the other Party's name, trade names, trademarks, service marks, and logos
     will inure to the benefit of the other Party.  Each Party further agrees
     not to use the other Party's name, trade names, trademarks, service marks,
     or logos as or with any part of any name, mark, or trade name of the Party
     or any Affiliate of the Party.  Without limiting any other provision of
     this Agreement, all uses by a Party of a name or logo of the other Party,
     whether on tangible materials or in communications in connection with the
     rendition of its duties hereunder, must conform to this Agreement and,
     where applicable, the policies and practices of the other Party furnished
     to the Party from time to time.

5.4  MOVEMENT OF CUSTOMERS. During the term of this Agreement, Ameritech shall
     not directly solicit the retail prepaid phone card business of those
     customers of Quest identified in ADDENDUM "C" attached hereto. Nothing
     herein contained shall prohibit Ameritech from responding to an unsolicited
     request for proposal from any such customer, or from pursuing the retail
     prepaid phone card business of such customer if that customer is no longer
     purchasing services from Quest.

5.5  PROPRIETARY SYSTEMS/TECHNOLOGY.  Ameritech acknowledges that the
     technologies and systems, including but not limited to software, procedures
     and methods of processing information, activation and refresh systems, and
     other proprietary information provided to Ameritech and used by Quest in
     connection with Quest's performance under this Agreement, are the sole and
     exclusive property of Quest.  Nothing contained herein shall convey to
     Ameritech any rights or interests in Quest's proprietary programs and
     systems, other than the right for Ameritech to use Quest's proprietary
     programs and systems during, subject to and in conjunction with the terms
     and conditions of this Agreement, and except as such use may be required by
     Ameritech upon or after the expiration or termination of this Agreement to
     continue to utilize the Customer records database and/or convert or
     transition the Customer records database to Ameritech and/or a third party
     of Ameritech's choosing.

5.7  REPORTS.  Attached as EXHIBIT "1" TO ADDENDUM "A" is a listing of the
     reports that Quest will supply to Ameritech on a weekly, monthly and other
     periodic basis, along with a description of the information contained in
     each such report.  The parties may by mutual agreement add or delete
     reports from the list, with a goal to establish an intranet account whereby
     Ameritech may electronically access the data in Quest's possession and
     prepare such reports on such a frequency as Ameritech deems appropriate.

                                  ARTICLE VI
                                CONFIDENTIALITY
                                ---------------
                                        
6.1  DUTY OF CARE.  Each Party acknowledges that any Confidential Information
     which may be provided to it by the other Party or which may be generated by
     a Party in performing its obligations under this Agreement may have
     substantial value to the Disclosing Party.  Accordingly, each Receiving
     Party agrees to take all reasonable and necessary steps to preserve the
     confidentiality of all Confidential Information received from a Disclosing
     Party, whether generated and/or communicated in writing, electronically,
     orally, or otherwise.  A receiving Party shall use not less than the same
     degree of care to avoid disclosure of such Confidential Information as it
     uses with respect to its own proprietary and confidential information of
     like importance and, at a minimum, shall exercise reasonable care.

6.2  CONFIDENTIAL INFORMATION.  For purposes of this Agreement, "Confidential
     Information" shall include, without limitation, the terms of this
     Agreement, Ameritech's Customer and End User lists and associated
     information, Quest's rates or agreements with its Carriers, and such other
     confidential engineering, technical, financial, business, marketing,
     promotional, usage and sales data as a Disclosing Party shall designate as
     "confidential," either in writing or orally.

6.3  RESTRICTIONS ON USE AND DISCLOSURE.  Each Party recognizes and acknowledges
     that a Disclosing Party is disclosing Confidential Information solely to
     facilitate full performance of this Agreement by both Parties and each
     Receiving Party agrees to, and shall, use the Confidential Information
     disclosed to it by the Disclosing Party solely in furtherance of this
     purpose and not for any other purpose.  A Receiving Party shall restrict
     disclosure of Confidential Information to such of its directors, officers,
     employees, and agents as shall have obligated themselves in writing to
     comply with the restrictions on use and disclosure contained in this
     Agreement and who have a reasonable need to know such information for such
     purpose and shall reproduce such information only to the extent necessary
     for such purpose.  A Receiving Party may disclose Confidential Information
     to a Consultant, but if it does so, it must ensure that the Consultant is
     obligated in writing to abide by the restrictions on use and disclosure
     contained in this Agreement and that the Confidential Information bears
     appropriate legends or statements indicating the confidential and/or
     proprietary nature of the information.  A receiving Party shall be liable
     for any violation of the provisions of this ARTICLE VI by any such
     Consultant.  Except as expressly provided otherwise herein, a Receiving
     Party shall not disclose Confidential Information to any third party.

*    Portions of this Agreement have been redacted to preserve the Company's
     confidential information.
<PAGE>
 
6.4  EXCEPTIONS.  The restrictions on disclosure by a Receiving Party of
     Confidential Information shall not apply to: (i) information which at the
     time of disclosure was generally available to the public; (ii) information
     which subsequent to its disclosure by the Disclosing Party to the Receiving
     Party is published or otherwise becomes available to the public through
     means other than an act or omission of the Receiving Party; (iii)
     information which was previously known to the Receiving Party free of any
     obligation to keep it confidential or which is subsequently and
     independently developed in good faith by the Receiving Party without
     reference to or use of the Confidential Information; and (iv) information
     rightfully acquired by a receiving Party in good faith from a third party
     on a non-confidential basis without breach of an agreement to maintain said
     information in confidence.  Notwithstanding anything to the contrary
     herein, a Receiving Party may disclose confidential Information if required
     to do so by law, or if ordered to do so by a court or other governmental
     authority of competent jurisdiction; provided, however, that a Receiving
     Party shall provide the Disclosing Party prior written notice of any such
     mandated disclosure and exercise its best efforts, consistent with sound
     business practice, both to afford the Disclosing Party an opportunity to
     contest the disclosure and to itself limit the extent of the disclosure to
     the maximum extent practicable.  Upon the requests of the Disclosing Party,
     the Receiving Party shall use its best efforts to negotiate with any court
     or governmental authority of competent jurisdiction that has compelled such
     disclosure an appropriate protective order that would permit review of any
     Confidential Information only by the court or appropriate staff of the
     governmental authority and would limit any further disclosure to the
     maximum extent possible.

6.5  OWNERSHIP.  Confidential Information disclosed to and/or generated by a
     Receiving Party is and shall remain the property of the Disclosing Party.
     By disclosing the Confidential Information to a Receiving Party, the
     Disclosing Party does not relinquish any of its proprietary rights and
     interests therein and hereby specifically reserves all such proprietary
     rights and interests to said Confidential Information.  A Receiving Party
     shall return (or, with the consent of the Disclosing Party, which shall not
     be unreasonably withheld, destroy) all Confidential Information and all
     copies thereof, including, without limitation, written and electronic
     copies, as well as all summaries, notes, or other documents, materials or
     things containing Confidential Information, to the Disclosing Party
     promptly upon the reasonable written requests of the Disclosing Party and
     upon termination of this Agreement.

6.6  INJUNCTIVE RELIEF.  In the event of a breach or threatened breach by a
     Receiving Party or its agents of the terms of this ARTICLE VI, the
     Disclosing Party shall be entitled to an injunction prohibiting such breach
     in addition to other legal and equitable remedies available to it in
     connection with such breach.  Each Party acknowledges that the Confidential
     Information of the other Party is valuable and unique and that the use or
     disclosure of such Confidential Information in breach of this Agreement
     will result in irreparable injury to the other Party.

6.7  SURVIVAL.  The Parties hereby agree that the confidentiality and non-use
     undertakings reflected in this ARTICLE VI shall survive the termination of
     this Agreement.

                                  ARTICLE VII

     cumulative and the exercise by a Party of any particular right or remedy
     shall not prevent such Party from exercising any other right or remedy.

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

11.1 MEDIATION.  The parties shall attempt in good faith to promptly resolve
     any dispute relating to this Agreement by negotiation between their
     executives who have authority to settle the controversy and who are at a
     higher level of management than the persons with direct responsibility for
     administration of this Agreement.  Either party may give the other party
     notice of any dispute not resolved in the normal course of business.
     Within fifteen (15) days after receipt of such notice, the receiving party
     shall submit to the other a written response.  The notice and response
     shall include (a) a statement of each party's position and a summary of
     arguments supporting that position, and (b) the name and title of the
     executive who will represent that party and of any other person who will
     accompany the executive.  Within twenty (20) days after receipt of the
     disputing party's notice, the executives of both parties shall meet at a
     mutually acceptable time and place, and thereafter as often as they deem
     reasonably necessary, to attempt to resolve the dispute.  Each party shall
     honor reasonable requests for information made by the other.  If the
     parties are unable to resolve the dispute within sixty (60) days of the
     disputing party's notice requesting mediation, then either party may
     initiate arbitration of the dispute as provided below.

11.2 ARBITRATION.  If the parties are unable to resolve a dispute by mediation
     as provided above, or if either party fails to resort to or comply with a
     request for such negotiation in a reasonable and timely fashion, then the
     exclusive remedy for resolving disputes between Ameritech and Quest
     relating to this Agreement shall be by binding arbitration in accordance
     with the Center for Public Resources ("CPR") Model Procedure for Mediation
     of Business Disputes.  One (1) arbitrator having experience in the data
     processing and/or telecommunications industry shall be selected by CPR to
     adjudicate any such dispute, and the arbitration shall be conducted on an
     expedited basis in the home city of the party against whom the arbitration
     is being invoked.  Each party shall bear its own expenses of the
     arbitration, and the cost and expenses of the arbitrator shall be equally
     shared by the parties.  The arbitration award shall be in writing and shall
     be final and binding upon the parties, and judgment thereon may be entered
     in any court of competent jurisdiction.

11.3 LIMITATION.  The requirements of this ARTICLE XI to utilize mediation and
     arbitration shall not apply to disputes between the parties for which
     injunctive relief is a remedy.  During the pendency of any mediation and
     arbitration conducted under this ARTICLE XI, both parties shall continue
     the full performance of their respective obligations under this Agreement.
     Negotiations pursuant to this ARTICLE XI are confidential and shall be
     treated as compromise and settlement negotiations for purposes of the
     Federal Rules of Evidence and State rules of evidence or any arbitration
     proceeding between the parties.

     10.2 must be in writing signed by the Party to whom compliance is owed, as
     specified in SECTION 10.1 above.  No waiver of any provision of this

     THIS AMENDMENT ("Amendment") is made this 13 day of November, 1997, to the 
Agreement dated September 30, 1997 (the "Agreement") between QUEST GROUP 
INTERNATIONAL, INC. ("Quest") and AMERITECH COMMUNICATIONS, INC. ("Ameritech").

                   ________________________________________


     Notwithstanding anything to the contrary in the Agreement, it is hereby 
agreed between Quest and Ameritech as follows:

     1.   Except as expressly provided to the contrary herein, terms used in 
this Amendment shall have the meaning defined in the Agreement.

     2.   Section 2.6 of the Agreement is amended by adding the following 
sentences as a new subsection (b) thereof:

          "(b)  Quest warrants that its Services and any information supplied by
          Quest to Ameritech hereunder shall properly perform Year 2000
          Processing. Quest shall promptly remedy any breach of this warranty at
          no additional charge to Ameritech by correcting its Services so as to
          make them capable of correctly performing Year 2000 Processing. 
          Quest's breach of this warranty shall not be subject to any provisions
          regarding limitations of Quest's liability set forth in this
          Agreement. "Year 2000 Processing" means processing which is dependent
          upon usage of calendar dates, including dates on or after January 1,
          2000. Year 2000 Processing includes, in addition to software provided
          by Quest, any third party software embedded in the Services that
          manages and/or manipulates data involving dates, including single
          century formulas and multi-century formulas. "Proper processing" means
          the Services will not cause an abnormally ending scenario or
          result in incorrect values generated involving dates."

     3.   The following is hereby added the Agreement or as a new Section 2.7:

     summarizing the various Transmission Services charges incurred by Ameritech
     during the immediately proceeding billing period. Quest's failure to
     forward an invoice within the prescribed time period shall not relieve or
     otherwise modify or alter in any way Ameritech's obligation to make the
     payments required herein; provided that, in no event will Quest invoice
     Ameritech for Services which were performed more than ninety (90) prior to
     the date of the invoice."

     5.   In the third sentence of Section 4.1(b) of the Agreement, the words

     Ameritech Customers identified in Addendum "C" or any other Ameritech
     Customer of whom Quest becomes aware as a result of Quest's performance of

     responding to an unsolicited request for proposal from any such customer,
     or from pursuing the retail prepaid phone card business of such customer if
     that customer is no longer purchasing services from Ameritech."

     9.   Except as expressly amended herein, the Agreement shall continue in 
full force and effect. In the event of any conflict, inconsistency or

delivered by Supplier in connection with this Agreement; (ii) declare all
amounts payable by Supplier to Ameritech hereunder immediately due and payable;
and (iii) exercise all other remedies available to it under this Agreement and
other such agreements and instruments otherwise available at law or in equity.

Each party's rights and remedies hereunder shall be cumulative and the exercise
by a party of any particular right or remedy shall not prevent such party from
exercising any other right or remedy.

1.12  POST-TERMINATION RESPONSIBILITIES
      ---------------------------------

Prior to the expiration or termination in whole or in part, of this Agreement,
and extending for a reasonable period of time beyond such termination or
expiration of this Agreement, if deemed necessary by Ameritech, Supplier shall
supply to Ameritech such reasonable support and assistance as Ameritech shall
specify to assist Ameritech in the orderly winding-down of the performance of
Services by Supplier and the transition of such services to Ameritech or to a
successor selected by Ameritech. These transition services shall include the
transfer of 800/888 access numbers and the transfer (and conversion to a
different database format, if necessary) of the 1-800-AMERITECH customers'
preferences, usage and other database information to Ameritech or its chosen
service provider. Ameritech shall pay for the transition services specified
herein in accordance with the pricing provisions hereof, or if not specified, at
Supplier's then-current prices.

Except as required pursuant to Subsection (a) hereof, upon the partial or
complete expiration or termination of this Agreement, each Party agrees to (i)
immediately cease all new use of the other Party's name, trade names, trademarks
and service marks, and logo; (ii) immediately deliver to the other Party any and
all materials not distributed bearing the other Party's name, trade names,
marks, or logos; and (iii) return all proprietary and confidential information
of the other Party to the other Party.  The obligations contained in this
Section shall survive the termination of this Agreement.

from any liability, obligation or agreement which, pursuant to any provision of
this Agreement, is to survive or be performed after such expiration or
termination.

complete a final true-up.  Within thirty (30) days of agreement on said true-up,
the parties shall settle all amounts due each other.

                                                                          Page 5

                                  ARTICLE TWO

2.01  ASSIGNMENT
      ----------

Neither party shall assign any right or obligation under this Agreement without
the other party's prior written consent. Any attempted assignment shall be void,
except that either party may assign monies due or to become due to it, provided
that (a) the assigning party gives the other party at least thirty (30) days
prior written notice of such assignment and (b) such assignment does not impose
upon the other party obligations to the assignee other than the payment of such
monies.

Notwithstanding the foregoing, Ameritech may assign this Agreement, in whole or
in part, to any of its Affiliates. Ameritech will provide Supplier with at least
thirty (30) days prior written notice of such assignment. Upon such assignment
and assumption of liability thereto by the assignee, Ameritech shall be
discharged of any subsequent liability under this Agreement.

Without limiting the generality of the foregoing, this Agreement shall be
binding upon and shall inure to the benefit of the parties' respective
successors and assigns.

Notwithstanding anything to the contrary herein, Ameritech hereby consents to
the Supplier granting a security interest in Supplier's rights under this
Agreement to any Lender providing financing to the Supplier, including Fleet
National Bank (as Administrative Agent) on behalf of certain lenders to secure
loans and other obligations of the Supplier and certain other related Parties
under a credit agreement among Teltrust Inc., its Affiliates and Fleet National
Bank.

Ameritech further consents to the exercise by Fleet of its rights and remedies
under that certain Credit Agreement, provided, however, Ameritech shall not be
deemed to have consented hereunder, and expressly reserves its right to consent
to the transfer of rights under the Agreement to any third party as a result of
the exercise by Fleet of such rights and remedies, provided that Ameritech shall
not unreasonably withhold its consent to such assumption or transfer.

2.02  AUDITS AND EXAMINATIONS
      -----------------------

(a) Upon reasonable advance written notice to Supplier, Ameritech shall be
entitled from time to time (but no more frequently than every six (6) months) to
audit (a) Supplier's books and records to confirm the accuracy of charges
invoiced and payments made by Supplier to Ameritech, (b) the database of calling
information to verify its accuracy and completeness, and (c) Supplier's
personnel and methods and procedures to verify Supplier's compliance with this
Agreement. Any such audit shall be performed at reasonably convenient times for
the Parties and during normal business hours. Any audit of the accuracy and
completeness of Supplier's invoices to Ameritech shall be limited to
transactions underlying those invoices submitted within one (1) year of
Ameritech's request for the audit. If any audit conducted by Ameritech reveals a
discrepancy of five percent (5%) or more, then Supplier shall reimburse
Ameritech's reasonable audit expenses. Nothing herein shall give Ameritech the
right to have access to any information other than that information related to
Ameritech's account.

(b)  Notwithstanding the foregoing, Ameritech shall be entitled to place one (1)
or more of its employees and/or consultants at Supplier's facilities in order to
audit the accuracy, correctness and completeness of 

                                                                          Page 6
<PAGE>
 
the Carrier's bills to Supplier for Services provided by Supplier pursuant to
this Agreement. Supplier shall furnish such employees/consultants reasonable
accommodations, facilities and assistance in this effort, and Ameritech shall
reimburse Supplier for any reasonable out of pocket expenses (to include such
expenses as telephone charges but not to include an allocation for rent, lights,
heat, etc.) incurred by Supplier in providing such accommodations, facilities
and assistance.

2.03  CHOICE OF LAW AND FORUM
      -----------------------

This Agreement and any claims arising hereunder or related hereto, whether in
contract or tort, shall be governed by the laws of Illinois, except provisions
relating to conflict of laws. Any suit arising out of or regarding this
Agreement which is brought by a party shall be filed in a court of competent
jurisdiction within the home State of the other party hereto.

2.04  COMPLIANCE WITH LAWS
      --------------------

Supplier and all persons furnished by Supplier shall comply with the provisions
of the Fair Labor Standards Act, the Federal Occupational Safety and Health Act,
environmental laws and all other applicable federal, state and local laws,
ordinances and regulations in the performance of this Agreement, including the
procurement of required permits and certificates.

Supplier shall maintain throughout the term of this Agreement all federal, state
and local licenses, permits, and certificates necessary to perform this
Agreement, which shall be promptly furnished to Ameritech upon request.

2.05  CONFIDENTIAL INFORMATION
      ------------------------

Duty of Care - Each Party acknowledges that any Confidential Information which
- ------------                                                                  
may be provided to it by the other Party or which may be generated by a Party in
performing its obligations under this Agreement may have substantial value to
the Disclosing Party. Accordingly, each Receiving Party agrees to take all
reasonable and necessary steps to preserve the confidentiality of all
Confidential Information received from a Disclosing Party, whether generated
and/or communicated in writing, electronically, orally, or otherwise. A
receiving Party shall use not less than the same degree of care to avoid
disclosure of such Confidential Information as it uses with respect to its own
proprietary and confidential information of like importance and, at a minimum,
shall exercise reasonable care.

Confidential Information -  For purposes of this Agreement, "Confidential
- ------------------------                                                 
Information" shall include, without limitation, the terms of this Agreement,
Ameritech's 1-800-AMERITECH Customer lists and associated information,
Supplier's rates or agreements with its Carriers, and such other confidential
engineering, technical, financial, business, marketing, promotional, usage and
sales data as a Disclosing Party shall designate as "confidential," either
orally or in writing.

Restrictions on Use and Disclosure - Each Party recognizes and acknowledges that
- ----------------------------------                                              
a Disclosing Party is disclosing Confidential Information solely to facilitate
full performance of this Agreement by both Parties and each Receiving Party
agrees to, and shall use the Confidential Information disclosed to it by the
Disclosing Party solely in furtherance of this purpose and not for any other
purpose.  A Receiving Party shall restrict disclosure of Confidential
Information to such of its directors, officers, employees, and agents as shall
have obligated themselves in writing to comply with the restrictions on use and
disclosure 

                                                                          Page 7
<PAGE>
 
contained in this Agreement and who have a reasonable need to know such
information for such purpose and shall reproduce such information only to the
extent necessary for such purpose. A Receiving Party may disclose Confidential
Information to a Consultant, but if it does so, it must ensure that the
Consultant is obligated in writing to abide by the restrictions on use and
disclosure contained in this Agreement and that the Confidential Information
bears appropriate legends or statements indicating the confidential and/or
proprietary nature of the information. A receiving Party shall be liable for any
violation of the provisions of this Article 2.05 by any such Consultant. Except
as expressly provided otherwise herein, a Receiving Party shall not disclose
Confidential Information to any third party.

Exceptions - The restrictions on disclosure by a Receiving Party of Confidential
- ----------                                                                      
Information shall not apply to: (i) information which at the time of disclosure
was generally available to the public; (ii) information which subsequent to its
disclosure by the Disclosing Party to the Receiving Party is published or
otherwise becomes available to the public through means other than an act or
omission of the Receiving Party; (iii) information which was previously known to
the Receiving Party free of any obligation to keep it confidential or which is
subsequently and independently developed in good faith by the Receiving Party
without reference to or use of the Confidential Information; and (iv)
information rightfully acquired by a receiving Party in good faith from a third
party on a non-confidential basis without breach of an agreement to maintain
said information in confidence. Notwithstanding anything to the contrary herein,
a Receiving Party may disclose confidential Information if required to do so by
law, or if ordered to do so by a court or other governmental authority of
competent jurisdiction; provided, however, that a Receiving Party shall provide
the Disclosing Party prior written notice of any such mandated disclosure and
exercise its best efforts, consistent with sound business practice, both to
afford the Disclosing Party an opportunity to contest the disclosure and to
itself limit the extent of the disclosure to the maximum extent practicable.
Upon the requests of the Disclosing Party, the Receiving Party shall use its
best efforts to negotiate with any court or governmental authority of competent
jurisdiction that has compelled such disclosure an appropriate protective order
that would permit review of any Confidential Information only by the court or
appropriate staff of the governmental authority and would limit any further
disclosure to the maximum extent possible.

Ownership - Confidential Information disclosed to and/or generated by a
- ---------                                                              
Receiving Party is and shall remain the property of the Disclosing Party. By
disclosing the Confidential Information to a Receiving Party, the Disclosing
Party does not relinquish any of its proprietary rights and interests therein
and hereby specifically reserves all such proprietary rights and interests to
said Confidential Information. A Receiving Party shall return (or, with the
consent of the Disclosing Party, which shall not be unreasonably withheld,
destroy) all Confidential Information and all copies thereof, including, without
limitation, written and electronic copies, as well as all summaries, notes, or
other documents, materials or things containing Confidential Information, to the
Disclosing Party promptly upon the reasonable written requests of the Disclosing
Party and upon termination of this Agreement.

Injunctive Relief - In the event of a breach or threatened breach by a Receiving
- -----------------                                                               
Party or its agents of the terms of this Article 2.05, the Disclosing Party
shall be entitled to an injunction prohibiting such breach in addition to other
legal and equitable remedies available to it in connection with such breach.
Each Party acknowledges that the Confidential Information of the other Party is
valuable and unique and that the use or disclosure of such Confidential
Information in breach of this Agreement will result in irreparable injury to the
other Party.

                                                                          Page 8

Survival - The Parties hereby agree that the confidentiality and non-use
- --------                                                                
undertakings reflected in this Article 2.05 shall survive the termination of
this Agreement.

2.06  FORCE MAJEURE
      -------------

Neither Ameritech nor Supplier shall be liable to the other for any delay or
failure in performance hereunder due to fires, strikes, stoppage of work,
embargoes, requirements imposed by governmental regulations, civil or military
authorities, acts of God, the public enemy or other causes which are beyond the
reasonable control of the party unable to perform (hereinafter "force majeure").
If a force majeure occurs, the party delayed or unable to perform shall give
immediate notice to the other party. In the event Supplier is the party delayed
or unable to perform, Ameritech may elect: (a) to terminate this Agreement
relating to Services not already performed without any further liability to
Supplier, or (b) to suspend performance for the duration of the force majeure,
during which period Ameritech may buy elsewhere substitute services. In the
event the parties established a commitment, purchase level or discount program,
the quantity bought or for which commitments have been made elsewhere shall be
deducted from such commitment, purchase level or discount program. Ameritech
shall not be obligated to pay for Services to the extent and for the duration
that performance thereof is delayed or prevented pursuant hereto. Ameritech's
exercise of its rights under option (b) shall not prevent Ameritech from
subsequently terminating this Agreement. Unless written notice of termination is
given by Ameritech, option (b) shall be deemed selected.

2.07  HEADINGS
      --------

The Clause headings inserted in this Agreement are for convenience only and
shall not affect the meaning or interpretation of this Agreement.

2.08  INDEMNITY
      ---------

Each party shall defend, indemnify and hold harmless the other and the other's
officers, directors, employees, and agents and their successors and assigns
against and from any and all losses, liabilities, suits, damages, claims,
demands, and expenses (including, without limitation, reasonable attorneys'
fees), whether based on contract or tort (including strict liability), arising
out of or in conjunction with this Agreement, but only to the extent that such
losses, liabilities, damages, claims, demands, and expenses arise out of or in
connection with, claims or lawsuits brought by unaffiliated third parties
alleging (1) the negligent or intentional acts or omissions of the indemnifying
party, its Affiliate(s) or subcontractors, or the officers, directors,
employees, agents, successors and assigns of any of them, (2) the failure of the
indemnifying party, its Affiliate(s) or subcontractors to fully comply with the
provisions of this Agreement, (3) defective or malfunctioning Services provided
hereunder, and (4) assertions under Worker's Compensation or similar laws made
by persons furnished by the indemnifying party. The indemnified party shall
promptly notify the indemnifying party of any written claim, loss, or demand for
which the indemnifying party is responsible under this Section.

Notwithstanding the foregoing, Ameritech shall indemnify, defend and hold
harmless Supplier from all liabilities, expenses, costs and damages (including
legal fees and expenses) related to any litigation or regulatory action
resulting from a challenge to Ameritech's authority or authorization to enter
into this Agreement, or to contract with Supplier to provide Services.

                                                                          Page 9

Ameritech and Supplier as joint employers of either Party's employees or agents
or Supplier as a special employer of any employee or agent of Ameritech.

Relationship of the Parties - Each of the Parties shall act as, and shall be,
- ---------------------------                                                  
independent contractors in all aspects of their performance of this Agreement.
Nothing contained in this Agreement shall authorize either Party to act as agent
for the other, nor grant either Party authority to make representations or
agreements on behalf of the other.  Nothing in this Agreement shall be deemed to
constitute or create a joint venture, partnership, pooling arrangement or other
formal business entity or fiduciary relationship between Supplier and Ameritech.
Nothing in this Agreement shall be construed to give any person or entity other
than Supplier and Ameritech any legal or equitable right, remedy or claim under
this Agreement or any provision contained herein.

2.10  INFRINGEMENT
      ------------

Supplier shall defend, indemnify and hold harmless Ameritech and its corporate
affiliates from and against any suits, claims, actions, losses, damages,
expenses (including attorneys' fees and costs) or liabilities that may result by
reason of any alleged violation, infringement or misappropriation of a United
States patent, trade secret, copyright or other proprietary right based on any
Services (including any materials and/or equipment utilized or supplied in the
performance of such Services) provided under this Agreement. Ameritech shall
promptly notify Supplier of any claim of infringement, violation or
misappropriation for which Supplier is responsible and shall cooperate with
Supplier to facilitate the defense or settlement of such claim. Supplier or
Supplier's attorney(s) shall keep Ameritech reasonably apprised of the
continuing status of the claim, including any lawsuit resulting therefrom, and
shall permit Ameritech, upon Ameritech's written request and at its own expense,
to participate in the defense or settlement of such claim.

If use of the Services shall be prevented or appears likely to be prevented by
court order or settlement resulting from any such claim, Supplier shall, at its
expense, either:  (a) by license or release from claim of violation,
infringement or misappropriation, procure for Ameritech the right to continue
receiving the Services; or (b) modify the Services so that they are functionally
equivalent to the original Services but are no longer subject to a claim of
violation, infringement or misappropriation; or (c) remove any infringing
materials and replace same with equally suitable materials free from claim of
violation, infringement or misappropriation.  Unless otherwise agreed in writing
by Ameritech, Supplier shall use its best efforts to procure the right for
Ameritech to use the Services as provided in (a) above.

2.11  INSURANCE
      ---------

Supplier shall maintain during the term of this Agreement: (a) Workers'
Compensation insurance as prescribed by the law of the State in which Supplier's
obligations under this Agreement are performed, (b) Employer's Liability
insurance with limits of at least $500,000 for each occurrence, (c) Commercial

<PAGE>
 
damage. Neither Supplier nor Supplier's insurer(s) shall have a claim, right of
action or right of subrogation against Ameritech based on any occurrence insured
against, in whole or in part, under the foregoing insurance. Supplier's policy
shall be endorsed to name Ameritech Corporation and its corporate affiliates as
additional insureds and state: "Ameritech Corporation is to be notified in
writing at least sixty (60) days prior to cancellation of or any material change
in this policy." Supplier shall furnish a copy of the endorsement and
certificate(s) evidencing the foregoing insurance coverage prior to commencement
of Services hereunder and, if applicable, annually thereafter during the term of
this Agreement. Supplier's purchase of insurance shall not in any way limit
Supplier's liability under this Agreement.

[***]


2.13  NONEXCLUSIVITY
      --------------

Other than as set forth in Section 1.03 above, this Agreement does not grant to
Supplier any exclusive right or privilege to provide to Ameritech services of
the type contemplated herein, and Ameritech reserves the right to contract with
other parties for the procurement of comparable services or to utilize its own
employees or employees of its corporate affiliates to provide comparable
services.

2.14  NONWAIVER
      ---------

Failure of either party to insist on performance of any term or condition of
this Agreement or to exercise any right or privilege hereunder shall not be
construed as a waiver of such term, condition, right or privilege in the future.

2.15  OFFSET
      ------

Both parties' obligations under this Agreement shall be subject to deduction of
any valid claim of one Party against the other Party arising under this
Agreement. Ameritech shall have the right to offset any valid claim related to
disputed amounts in the Quarterly true-up against amounts due under the Billing
and Collection Agreement. Neither Party shall be obligated to make payments
required hereunder during which time such payments are in dispute. The Parties,
however, shall continue performing their respective obligations during such
dispute. Immediately following resolution, a Party shall be responsible for any
amounts due and owing as a result of such dispute.

If either party disputes any calculation or amount shown on an invoice or
payment, it shall notify the other party of such dispute and the basis therefor
within twenty (20) business days after receipt of such invoice.  The non-
disputing party shall respond to the disputing party in writing within ten (10)
business days of its receipt of such a notice.  If the dispute is not resolved

and Supplier shall in good faith attempt to resolve such dispute through
mediation and arbitration in accordance with Article Three hereof.

2.16  PUBLICITY
      ---------

materials without Ameritech's prior written permission.

addition to any other remedies available at law or in equity.

2.18  SEVERABILITY
      ------------

If any provision of this Agreement shall be held invalid or unenforceable, such
provision shall be deemed deleted from this Agreement and shall be replaced by a

continue in full force and effect.

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

Supplier shall not engage or make use of subcontractors for the purpose of
providing Services hereunder, except as authorized in writing by Ameritech.  The
foregoing shall not include Installers, Programmers, Consultants or Third Party

Ameritech for the acts and omissions of any of Supplier's subcontractors 

                                                                         Page 12

2.21  SUSPENSION OF PERFORMANCE
      -------------------------

If bankruptcy proceedings are commenced with respect to Supplier and if this
Agreement has not been otherwise terminated, then Ameritech may suspend all
future performance of this Agreement until Supplier assumes and provides
adequate assurance of future performance or rejects this Agreement pursuant to
(S)365 of the Bankruptcy Code or any successor provision.  Any such suspension
of further performance by Ameritech pending Supplier's assumption or rejection
will not be a breach of this Agreement and will not affect Ameritech's right to
pursue or enforce any of its rights under this Agreement or otherwise.

2.22  TAX
      ---

Supplier shall be solely responsible for the payment of all applicable federal,
state and local excise sales and use taxes to the proper jurisdiction on all
Services provided by Supplier.  Each party shall pay or cause to be paid, when
due, all federal, state and local taxes payable with respect to the revenues and
profits recognized by that party hereunder.  Ameritech shall not be held liable
for Supplier's failure to pay the appropriate tax amounts to the proper
jurisdiction, unless such underpayment is due to Ameritech's failure to properly
assess, collect and remit the appropriate tax amount to Supplier, and provide
Supplier with the appropriate tax information for tax returns.  In such case,
Ameritech shall be liable for any such underpayment, including interest and
penalties.

2.23  WARRANTY

purpose.  In no event shall Supplier be liable for any act or omission of any
Ameritech-approved carriers or suppliers from whom Supplier obtains net-

or its End Users.

2.24  YEAR 2000 CAPABILITIES
      ----------------------

Supplier warrants that its Services and any information supplied by Supplier to
Ameritech shall properly perform Year 2000 Processing. Supplier shall promptly
remedy any breach of this warranty at no additional charge to Ameritech by

2000 Processing. Supplier's breach of this warranty shall not be subject to any
provisions regarding limitations of Supplier's liability set forth in this
Agreement. "Year 2000 Processing" means processing which is dependent upon usage
of calendar dates, including dates on or after January 1, 2000. Year 2000

                                                                         Page 14

2.28  MUTUAL ACCOMMODATION
      --------------------

If and to the extent it will not place a party in breach of an agreement that
party has with its carriers or other suppliers, or it is not otherwise a
violation of any federal, state or local law, ordinance or regulation, the
parties shall periodically discuss the arrangements each has with carriers for
their telecommunications traffic and other related products and services.  The
parties shall in good faith look for opportunities to reduce their respective
costs and expenses by aggregating purchasing volumes in new contractual
arrangements or by allowing one party to purchase under or through the other
party's contract(s).

                                 ARTICLE THREE
                                        
3.01  MEDIATION
      ---------

The parties shall attempt in good faith to promptly resolve any dispute relating
to this Agreement by negotiation between their executives who have authority to
settle the controversy and who are at a higher level of management than the
persons with direct responsibility for administration of this Agreement. Either
party may give the other party notice of any dispute not resolved in the normal
course of business. Within fifteen (15) days after receipt of such notice, the
receiving party shall submit to the other a written response. The notice and
response shall include (a) a statement of each party's position and a summary of
arguments supporting that position, and (b) the name and title of the executive
who will represent that party and of any other person who will accompany the
executive. Within twenty (20) days after receipt of the disputing party's
notice, the executives of both parties shall meet at a mutually acceptable time
and place, and thereafter as often as they deem reasonably necessary, to attempt
to resolve the dispute. Each party shall honor reasonable requests for
information made by the other. If the parties are unable to resolve the dispute
within sixty (60) days of the disputing party's notice requesting mediation,
then either party may initiate arbitration of the dispute as provided below.

3.02  ARBITRATION
      -----------

If the parties are unable to resolve a dispute by mediation as provided above,
or if either party fails to resort to or comply with a request for such
negotiation in a reasonable and timely fashion, then the exclusive remedy for
resolving disputes between Ameritech and Supplier relating to this Agreement
shall be by binding arbitration in accordance with the Center for Public
Resources ("CPR") Model Procedure for Mediation of Business Disputes.  One (1)
arbitrator having experience in the data processing and/or telecommunications
industry shall be selected by CPR to adjudicate any such dispute, and the
arbitration shall be conducted on an expedited basis in the home city of the
party against whom the arbitration is being invoked.  Each party shall bear its
own expenses of the arbitration, and the cost and expenses of the arbitrator
shall be equally shared by the parties.  The arbitration award shall be in
writing and shall be final and binding upon the parties, and judgment thereon
may be entered in any court of competent jurisdiction.

3.03  LIMITATION
      ----------

The requirements of this Article Three to utilize mediation and arbitration
shall not apply to disputes between the parties for which injunctive relief is a
remedy. During the pendency of any mediation and arbitration conducted under
this Article Three, both parties shall continue the full performance of their
respective obligations under this Agreement. Negotiations pursuant to this
Article Three are confidential

                                                                         Page 15
<PAGE>
 
and shall be treated as compromise and settlement negotiations for purposes of
the Federal Rules of Evidence and State rules of evidence or any arbitration
proceeding between the parties.

                       PERFORMANCE METRICS AND PENALTIES


DELAYS BY SUPPLIER
- ------------------

Time is of the essence in Supplier's performance of its obligations under this
Agreement.  If Supplier has knowledge that anything prevents or threatens to
prevent timely performance under this Agreement, Supplier shall immediately
notify Ameritech thereof, provided that such notification shall not relieve
Supplier of the requirement set forth in the preceding sentence.  Ameritech
shall review such notice, and if Ameritech determines it is not adversely
affected by such delay, then Ameritech shall consent in writing to such delay
and the paragraph below shall not apply, unless Supplier subsequently fails to
meet the extended date, in which event such paragraph shall apply retroactively
from the original date if Ameritech does not consent in writing to such further
delay.

If Supplier fails to provide Ameritech Services in accordance with the terms and
conditions set forth in this Agreement on or before April 15, 1998, (and consent
to an extension is not granted by Ameritech) and such failure is not primarily
and directly attributable to Ameritech's failure to perform those obligations
identified in this Agreement as being Ameritech's only responsibility Ameritech
or any of the reasons covered in the Clause entitled "Force Majeure," then
because damages to Ameritech arising from such delay would be difficult if not
impossible to ascertain, Ameritech shall be entitled to receive as liquidated
damages, and not as a penalty the following non-cumulative amounts as scheduled
until such Services are provided.  After sixty (60) days delay either party
shall have the option to terminate this Agreement.

        1-  7 Days delay  [***] 
        8- 14 Days delay  [***] per day

PERFORMANCE
- -----------

If after initial acceptance, Supplier fails to provide to Ameritech the Services

Agreement may be terminated by either party.

PROJECTIONS
- -----------

Ameritech agrees to provide Supplier with Quarterly forecasts no later than
forty five (45) days prior to each Quarter, so that Supplier can adequately
staff to provide Services.  In the event Ameritech materially overestimates the
volume of Services which are actually generated and Supplier incurs costs for
over-staffing, Ameritech agrees to reimburse Supplier for its actual costs
incurred in connection with said over-staffing.  In the event Ameritech
materially underestimates the volume of Services which are actually generated,
and Supplier is unable to meet the Service standards set forth in Attachment A
as a result of said underestimate, Supplier shall be released of meeting said
standards until it can reasonably increase its staff to meet the Service demand.

For purposes of this Paragraph, a "material overestimate/underestimate" shall be
more than [***] variance.
