ITEM 1:   DESCRIPTION OF BUSINESS

USTN Holdings, Inc., and its wholly-owned subsidiary Illuminet, Inc.,
(collectively referred to as ("ILLUMINET") were incorporated in the State of
Delaware on August 2, 1995 to effect the merger of U.S. Intelco Holdings, Inc.
("U.S. Intelco") and Independent Telecommunications Network, Inc. ("ITN").  In
accordance with terms of the merger, U.S. Intelco and ITN merged with and into
USTN Services, Inc. ("USTN Services") on February 23, 1996 (the "Merger").
USTN Services subsequently changed its name to Illuminet, Inc.

The Merger was accounted for as a purchase  business  combination  in accordance
with generally  accepted  accounting  principles with U.S. Intelco designated as
the acquiring company.  Accordingly,  the consolidated  statements of operations
and cash flows for the year  ended  December  31,  1995  presented  in this Form
10-KSB  represent the  stand-alone  results of operations and cash flows of U.S.
Intelco.  The  results of ITN's  operations  are  included  in the  consolidated
financial  statements  prospectively  from the date of the Merger. The pro forma
information  presented in the  Management's  Discussion  and Analysis or Plan of
Operations item reflects the combined  activities of U.S.  Intelco and ITN as if
the Merger had occurred effective January 1, 1995.

ILLUMINET is engaged in the  business of  developing,  managing and  marketing a
Signaling System 7 ("SS7") network and related products and services based on SS
technology  to the  entire  telecommunications  marketplace,  including  network
services  and other  products  and  services  to the  cellular  market.  SS7 is
a telecommunications  industry-standard system of protocols and procedures that
is used to control  telephone  communications  and provide  routing  information
in association with vertical calling  features,  such as card validation,  
Advanced Intelligent Network ("AIN") services, cellular services, 800 Number 
Portability, and Calling Name Delivery.  Additionally,  ILLUMINET provides 
advanced data base services,  billing-and-collection services, and calling card
services to a range of telephone companies as well as inter-exchange carriers
("Carriers"), operator service providers ("OSPs") and other telecommunications 
companies and providers of telecommunications services.  ILLUMINET  primarily  
provides services to companies in the  telecommunications  industry that are 
located throughout the United States and considers all of its operations as 
one segment.

COMPETITION

     The  advanced  data base,  billing  and  collection,  calling  card and SS7
network  services  offered  by  ILLUMINET  are  offered  by a  number  of  other
companies. In the area of billing-and-collection services, ILLUMINET competes
with Independent NECA Services, a New Jersey-based company. Each of the Regional
Bell Operating  Companies  ("RBOCs") created by the AT&T break-up,  Southern New
England  Telephone  Company  ("SNET"),   Sprint  Corporation   ("Sprint"),   MCI
Communications  Corporation  ("MCI"),  and GTE Corporation  ("GTE") operate line
information data bases and SS7 networks that are in competition with ILLUMINET's
services. In addition, a few state  telecommunications  associations have formed
intrastate networks to provide services to member companies. These are primarily
equal access and facilities networks;  however, their associations with carriers
could allow these statewide  associations  to offer  competing  calling card and
marketing services on a local level.

     Although  ILLUMINET's  network  may be similar  to the other SS7  networks,
ILLUMINET believes its network offers its customers significant advantages apart
from the  technology.  Since the  ILLUMINET  network  is  dedicated  to  serving
customers without competing with them, customers provide viewpoints on

                              -3-
<PAGE>
services  offered by the network and the timing of the delivery of such services
without the concern of aiding their competitors.

REGULATION

     ILLUMINET does not provide voice-grade or data telecommunications  services
to the public.  ILLUMINET  will  provide  facilities  and  services on a private
contractual  basis to other  entities in the  telecommunications  industry which
will utilize the services and  facilities in their  provision of both  regulated
and nonregulated  telecommunications  services. In as much as ILLUMINET does not
provide voice-grade or data common carrier  telecommunications  services,  it is
anticipated  that the  construction  of facilities  and provision of services by
ILLUMINET  will not be subject to regulation by the FCC or state public  utility
commissions.

SUPPLIERS

     Certain aspects of ILLUMINET's  services  incorporate  services or products
provided by third parties. For example,  Ameritech Corp. provides the data base
used in ILLUMINET's  800 data base services which allow carriers to query an 800
data base to obtain screening and routing information for originating 800 calls.
Additionally,  several  inter-exchange  carriers provide data transmission lines
that are integral to  ILLUMINET's  SS7 network.  The providers of these services
are not the only  available  sources of such services.  Consequently,  ILLUMINET
believes  that if  necessary,  such  services can be obtained  from  alternative
vendors at competitive rates.

INTELLECTUAL PROPERTY

    ILLUMINET relies on a combination of copyright, trademark, trade secret,
unfair competition and other intellectual property laws, a patent,
confidentiality procedures and contractual provisions to protect its
proprietary rights.  Such protections, however, may not be adequate to prevent
misappropriation of such rights and may not preclude competitors from
independently developing services similar to the ILLUMINET's services.  The
technology  underlying  ILLUMINET's  patent is a usage measurement  system for a
telephone signaling network. The patent will expire on January 18, 2010. As part
of a patent  settlement  arrangement,  ILLUMINET has granted UNISYS  Corporation
("UNISYS") a non-exclusive,  irrevocable, fully paid license to make, have made,
sell, offer to sell and/or use products, systems, methods and/or processes under
the patent.  The license  granted to UNISYS does not include any right of UNISYS
in or to any particular  technology of ILLUMINET which embodies the patent, such
as ILLUMINET's INMART or AMAT7 (TM) software. From time to time ILLUMINET
receives or solicits inquiries for the sale or licensing of certain of its 
assets, including the patent, which it will consider on a case-by-case basis.

EMPLOYEES

     As of December 31, 1996, ILLUMINET had 199 full time employees.

ITEM 2:   DESCRIPTION OF PROPERTY

     ILLUMINET's headquarters and a portion of its operations center are located
in Lacey,  Washington,  where it owns a 70,000 square foot facility.  The 
building, approximately  13.7  acres of land on which the  building  is 
constructed,  and certain of  ILLUMINET's  computer  hardware  and  software are
financed by Rural Telephone  Finance  Cooperative  ("RTFC").  RTFC  has a first
priority  lien on substantially all of ILLUMINET's assets,  revenues and
property,  excluding cash collected  and held on  behalf  of others  in the  
normal course of providing ILLUMINET's services.

                                   -4-
<PAGE>

     ILLUMINET  also leases 18,683 square feet of office space in Overland Park,
Kansas,  where in addition  to certain  selling  and  administrative  functions,
ILLUMINET has its Network  Surveillance and Control Center (NSCC) which operates
on a 24-hour a day basis,  7 days a week.  The lease term began  August 16, 1993
and  expires  August  15,  1998,  with an  option  to renew  the  lease  for two
additional five-year periods.

     ILLUMINET's  network  operations  include  redundant Signal Transfer Points
("STPs") facilities located in Mattoon, Illinois, and Rock Hill, South Carolina.
Additional STP facilities are currently being installed in Lacey, Washington and
Las  Vegas,  Nevada.  ILLUMINET  has  subleased  4,657  square  feet for its STP
facilities   at  Mattoon,   Illinois  in  the   headquarters   of   Consolidated
Communications,  Inc., a shareholder of ILLUMINET.  The sublease expired on July
31, 1996,  and was renewed under one of the three  additional  five-year  period
renewal  options.  ILLUMINET  leases 6,468 square feet for its STP facilities at
Rock Hill,  South  Carolina,  of which it subleases 1,243 square feet to another
party.  The lease  expired  April 30, 1996,  and was renewed  under one of three
additional  five-year  period  renewal  options.  In  February  1997,  ILLUMINET
negotiated a five-year  lease expiring in December 2001 for 600 square feet with
an unrelated party for its STP facilities at Las Vegas, Nevada.

ITEM 3:  LEGAL PROCEEDINGS

     On  February  6, 1996,  one ITN  shareholder  filed a lawsuit  in  Delaware
Chancery  Court  against  ITN and its board of  directors  alleging  breaches of
fiduciary  duty on the  part of the ITN  board  of  directors  related  to their
approval  of the  Merger  into  ILLUMINET.  In  February  1997,  this  suit  was
voluntarily dismissed without prejudice by the plaintiff.

ITEM 4:   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matter was submitted  to a vote of security  holders  during the fourth
quarter of 1996.

                                     PART II

ITEM 5:   MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

     There  are no  established  public  trading  markets  for  shares  of  USTN
Holdings,  Inc. Common Stock ("USTN Common Stock") or USTN Holdings, Inc. Series
A Preferred Stock ("USTN Series A Preferred").

     At December 31, 1996,  USTN  Holdings,  Inc. had 267 holders of USTN Common
Stock (43 of which also hold USTN Series A Preferred  Stock),  and 78 holders of
USTN Series A Preferred Stock (43 of which also hold USTN Common Stock).

     When authorized by the USTN Holdings, Inc. Board of Directors,  payments of
dividends are  restricted  under  ILLUMINET's  long-term debt  arrangements,  as
follows:  (1) approval of RTFC is required unless ILLUMINET's ratio of equity to
total assets  exceeds 40% and (2) dividends are  restricted to 75% of net income
as defined in the indenture  relating to the USTN debentures.  Dividends are not
payable to USTN Series A Preferred  Stock unless  dividends  are  declared,  set
aside or paid simultaneously to holders of USTN Common Stock. To date, no 
dividends have been declared.

ITEM 6:   MANAGEMENT'S DISCUSSION AND ANALYSIS OR
          PLAN OF OPERATIONS

BASIS OF PRESENTATION

USTN Holdings, Inc., and its wholly-owned subsidiary, Illuminet, Inc.
(formerly named USTN Services, Inc.), (collectively referred to as
("ILLUMINET"), were incorporated for the purpose of effecting the merger of
U.S. Intelco Holdings, Inc. ("U.S. Intelco") and Independent
Telecommunications Network, Inc. ("ITN") that was consummated effective
February 23, 1996 ("Merger").  The Merger was accounted for as a purchase
business combination in accordance with generally accepted accounting
principles, with U.S. Intelco designated as the acquiring company.
Accordingly, the consolidated statements of operations and cash flows for the
year ended December 31, 1995, and the balance sheet as of December 31, 1995,
represent the stand-alone results of operations and cash flows of U.S.
Intelco. The results of ITN's operations are included in the consolidated
financial statements prospectively from the date of the Merger.  The pro forma
information presented in this Management's Discussion and Analysis or Plan of
Operations reflects the combined activities of U.S. Intelco and ITN as if the
Merger had occurred effective January 1, 1995.

Billing-and-collection  services  revenues  for 1996  increased  primarily  as a
result of a $966,926,  or 18%, increase in clearinghouse  product line revenues.
This increase reflects a 28% increase in messages processed from 53.7 million in
1995 to 68.8  million in 1996,  due to the  addition of a large  customer in the
second quarter of 1995. Although  clearinghouse volumes are expected to increase
in 1997,  revenues are expected to remain at 1996 levels due to a fourth quarter
1996 price decrease.

Data  base  services  revenues   decreased,   reflecting  a  reduction  in  Line
Information  Data Base ("LIDB")  product line revenues  offset by an increase in
Calling Name Delivery  ("CNAM") product line revenues.  LIDB revenues  decreased
$550,810,  or 9%, in 1996,  reflecting a 10% decrease in queries  processed from
177.0 million in 1995 to 159.3 million in 1996. This was due to increased market
penetration by competing calling card service providers. CNAM revenues increased
$552,822,  or 385%, in 1996, reflecting growing market acceptance of the service
introduced in 1995.

Network usage  measurement  revenues  derived from the sale of  ILLUMINET's  SS7
network traffic tracking and measurement software products AMAT7 (RM) and CDR7
(RM) decreased in 1996 due to  finalization of sales that began in late 1995. No
new sales were completed in 1996.

Other  services  revenues  decreased  primarily  due to Personal  Communications
Services ("PCS") revenues decreasing $332,567, or 67%, in 1996. This decrease is
due to a change in focus from PCS limited  partnership  sponsorship  activities,
with the  completion of the Federal  Communications  Commission  ("FCC") C Block
broadband  radio  spectrum  license  auction,  to  new  service  offerings.   As
anticipated,  ILLUMINET's  contract to provide voice messaging  services for the
State  of  Washington  was not  renewed  in  September,  1996.  Voice  messaging
contributed  revenues of $801,283 and  $548,408  for the 1995 and 1996  periods,
respectively.  ILLUMINET's  independent  customer survey program which generated
revenues of $146,031 in the 1995 period was  discontinued  in late 1995,  as its
market cycle ended.

                                  -7-
<PAGE>
Intelligent  network services revenues for 1996 increased  primarily as a result
of a  $1,405,785,  or 42%,  increase  in trunk  signaling  and  related  service
revenues,  reflecting  new customer  growth.  800 switch and transport  revenues
increased  $333,260,  or 8%,  in 1996,  reflecting  volume  growth  from a large
customer. Network connectivity product line revenues increased $728,925, or 10%,
from growth in chargeable customer links. Offsetting the revenue growth in these
product lines, LIDB switch and transport revenues decreased $1,255,979,  or 24%,
in 1996 due to reduced prices brought on by competition.

Wireless  services  revenue  increased  primarily due to a $1,689,348,  or 101%,
increase  in 1996 in  cellular  switch  and  transport  revenues.  The  increase
reflects  customer growth and increased  utilization of the network with message
volumes  increasing  211% from  403.5  million  for the 1995  period to  1,253.9
million for the comparable 1996 period.  The growth was offset by an approximate
60%  decrease  in price due to  competition.  Other new  services  delivered  to
wireless service providers beginning in 1995 and 1996 contributed an increase in
revenues of $478,000 over 1995 levels with increases in volumes processed.

EXPENSES. ILLUMINET's primary costs are related to network expenses, followed by
personnel  costs,  depreciation  and  amortization  of  hardware,  software  and
facilities  assets,  and  software  maintenance  expenses.   Expenses  increased
$14,827,070,  or 77%,  from  $19,157,731  to  $33,984,801  for the  years  ended
December 31, 1995 and 1996,  respectively.  The increase  reflects ten months of
combined  expenses  resulting  from the Merger.  On a pro forma basis,  expenses
decreased $2,212,779, or 6%, from $39,908,494 for the 1995 period to $37,695,715
for the comparable 1996 period.

Pro forma operating expenses decreased $1,594,048,  or 13%, from $11,864,041 for
the 1995 period to $10,269,993 for the comparable 1996 period.  This decrease is
caused primarily by reduced  PCS-related  business  development costs,  software
maintenance  savings related to cost reduction  projects  completed in 1995, and
reduced personnel costs. The decrease in PCS business  development costs results
from a change in focus from PCS limited partnership sponsorship activities, with
the completion of the FCC C Block broadband radio spectrum license  auction,  to
new service  offerings  requiring a lower level of resources.  Operating expense
savings were offset by increased operating costs related to the AMAT7 and CDR7
computer software  products.  Illuminet  completed development and market 
introduction of AMAT7 and CDR7 in mid-1995 and the end of 1995, respectively.

Pro forma selling, general and administrative expenses decreased $1,490,336,  or
14%, from $10,976,647 to $9,486,311 for the 1995 and 1996 periods, respectively,
due to a reduction in personnel costs as well as expenses  related to litigation
settled  in 1995 to protect  ILLUMINET's  patent on a common  channel  signaling
usage measurement system.  Selling,  general and administrative  expense savings
are offset by  one-time  implementation  costs that  resulted  from the  Merger,
including  legal  fees  and  new  marketing  material  printing  costs.  Network
operating expenses increased $1,433,735,  or 15%, from $9,629,291 to $11,063,026
for the 1995 and 1996 periods,  respectively,  due to increased  leased  network
connectivity,  link, and LATA access charges  incurred to establish and maintain
customer connectivity to the SS7 network.

On a pro forma basis, depreciation and amortization expenses increased $791,171,
or  15%,  from   $5,384,339  to  $6,175,510  for  the  1995  and  1996  periods,
respectively,  primarily due to  depreciation  and  amortization  of capitalized
computer  software costs  associated  with the AMAT7 and CDR7  products,  and to
operating  hardware and software  placed into  production  in the second half of
1995  and  1996.  Corporate   realignment   expenses,   comprised  primarily  of
Merger-related severance expenses, decreased $1,353,301, or 66%, from $2,054,176
to $700,875 for the 1995 and 1996  periods,  respectively,  primarily due to the
completion of Merger activities in the first quarter of 1996.

                                -8-

INTEREST INCOME/INTEREST EXPENSE. Interest income increased by $204,099, or 75%,
from  $271,026  for the year  ended  December  31,  1995,  to  $475,125  for the
comparable  1996 period.  This increase  resulted  primarily from an increase in
available cash balances over the two periods resulting from the Merger.

On a pro forma basis,  interest income decreased by $3,388, or 1%, from $495,918
for the 1995 period to $492,530 for the 1996 period.

Interest expense increased $873,674,  or 199%, from $439,625 for the 1995 period
to $1,313,299 for the 1996 period.  The increase reflects ten months of combined
interest expense resulting from the Merger, a higher aggregate  outstanding debt
balance resulting from two additional  twenty-year mortgage loans for a total of
approximately  $2.7 million  obtained from Rural Telephone  Finance  Cooperative
("RTFC") in March,  1995,  and a loan obtained from RTFC in October,  1995,  for
approximately $1.1 million.

On a pro forma basis, interest expense decreased $93,706, or 6%, from $1,621,437
for the 1995 period to $1,527,731 for the comparable 1996 period.

INCOME TAXES.  ILLUMINET has Federal income tax net operating loss carryforwards
available  to offset  future  taxable  income for  Federal  income tax  purposes
totaling  $20,964,492.  These carryforwards  expire in various amounts from 2006
through  2011.   ILLUMINET's   ability  to  utilize  such  net  operating   loss
carryforwards is dependent on ILLUMINET's ability to generate sufficient taxable
income from its  operations.  The current  1997 tax  provision  is  comprised of
Federal alternative minimum taxes which cannot be completely offset by tax loss
carryforwards.

EARNINGS

ILLUMINET's net income increased  $4,468,441 from a net loss of $(1,515,459) for
the year ended December 31, 1995, to net income of $2,952,982 for the comparable
1996  period.  This  increase  primarily  reflects an increase in  clearinghouse
revenues,  cellular  switch and transport  revenues,  a decrease in PCS business
development  costs,  and  the  impact  of the  Merger  on  reducing  costs  as a
percentage of revenues.

On a pro forma basis,  ILLUMINET's  net income  increased  $4,108,233 from a net
loss of  $(1,253,965)  to net income of $2,854,268  for the years ended December
31, 1995 and 1996,  respectively,  primarily  resulting  from  positive  revenue
trends offset by one-time Merger costs incurred in 1996.

ILLUMINET  believes that it will achieve  higher  earnings in the future through
new  product  and   customer   diversification   and   expansion   into  related
telecommunications markets. ILLUMINET anticipates that increased expenditures in
the  development  of services and products  will  continue over the next several
years.  While it is anticipated  that the existing primary services and products
will continue to be profitable,  overall  profitability  in the immediate future
could be negatively impacted by delays in obtaining new product revenues coupled
with  related  increases  in new  product  start-up  costs.  A general  downward
pressure on price caused by increased  competition  may also  negatively  impact
profitability.

LIQUIDITY AND CAPITAL RESOURCES

U.S. Intelco and ITN individually relied on a combination of cash generated from
operations,  debt and equity to fund their  service  development  and  expansion
activities.  Currently, ILLUMINET's operating activities are generating positive
cash flows.  However,  as ILLUMINET  broadens its services and products to those
requiring  larger  investments  coupled with longer  periods  before  subsequent
revenues are generated,  ILLUMINET  believes there may be increased  pressure on
cash generated from operations. ILLUMINET anticipates

                                -9-
<PAGE>
continued  high levels of  investment  in the  development  of new  services and
products over the next several years as ILLUMINET  processes  increased  volumes
relating to its network,  data base, and  billing-and-collection  services,  and
broadens its product base to keep pace with changing markets and customer needs.

ILLUMINET's  working  capital  (current  assets minus current  liabilities)  was
$6,458,504  as of  December  31,  1996.  ILLUMINET's  cash and  cash  equivalent
balances include $7,709,000  required as working capital to service  ILLUMINET's
clearinghouse  customers.  Such funds are  received  and  disbursed on a monthly
basis. The increase in working capital of $2,362,670 from $4,095,834 at December
31, 1995,  reflects  the increase in cash  balances  from  operating  activities
offset by an increase in liabilities  assumed in the Merger  including  accruals
for  network  expenses  and the current  portion of  long-term  debt  financing.
ILLUMINET believes that its existing cash balances, funds generated from its 
operations and borrowings available under its existing credit agreements will be
sufficient to meet existing  capital  expenditure and working capital needs for
the immediate future.

ILLUMINET's expenditures for property and equipment were $5,463,559 for the year
ended December 31, 1996.  Expenditures for property and equipment were primarily
for network equipment.

At December 31, 1996,  ILLUMINET has a secured line of credit  expiring  August,
2001, with RTFC that permits ILLUMINET to borrow up to $7,300,000, not to exceed
80% of accounts receivable.  There were no borrowings against the line of credit
at December  31,  1996.  In December,  1996,  ILLUMINET  drew against one of its
existing  mortgage  notes  totaling  $2,680,765  to finance the expansion of the
network with the purchase of additional  switching  equipment.  Additionally  at
December  31,  1996,   ILLUMINET  has  $5,188,007  of  unused  loan   facilities
established or committed with RTFC, maturing in the years 2000 and 2001.

                  Notes to Consolidated Financial Statements

                                December 31, 1996


Note 1:  Summary of Significant Accounting Policies
- ---------------------------------------------------

Description of Business and Basis of Presentation
- -------------------------------------------------

USTN Holdings, Inc., and its wholly-owned subsidiary Illuminet, Inc.,
(collectively referred to as "ILLUMINET") were incorporated in the State of
Delaware on August 2, 1995, to effect the merger of U.S. Intelco Holdings,
Inc. ("U.S. Intelco") and Independent Telecommunications Network, Inc.
("ITN").  In accordance with terms of the merger, U.S. Intelco and ITN merged
with and into USTN Services, Inc. ("USTN Services") on February 23, 1996 (the
"Merger").  USTN Services subsequently changed its name to Illuminet, Inc.
The Merger was accounted for as a purchase combination with U.S. Intelco
designated as the acquiring company.  Accordingly, references to USTN
Holdings, Inc. and ILLUMINET in the accompanying financial statements and
related notes for the periods prior to the Merger represent U.S. Intelco,
while references to USTN Holdings, Inc. and ILLUMINET for the periods after
the Merger represent the consolidated entity including the net assets and
operations of ITN (see Note 2).

ILLUMINET is engaged in the  business of  developing,  managing and  marketing a
Signaling  System 7 ("SS7")  network and related  products and services based on
SS7 technology to the entire telecommunications  marketplace,  including network
services  and other  products  and  services to the  cellular  market.  SS7 is a
telecommunications  industry-standard system of protocols and procedures that is
used to control  telephone  communications  and provide  routing  information in
association with vertical calling  features,  such as card validation,  Advanced
Intelligent Network ("AIN") services, cellular services, 800 Number Portability,
and Calling Name Delivery.  Additionally,  ILLUMINET provides advanced data base
services,  billing-and-collection services, and calling card services to a range
of telephone companies as well as interexchange carriers ("Carriers"),  operator
service providers ("OSPs") and other telecommunications  companies and providers
of  telecommunications   services.  ILLUMINET  primarily  provides  services  to
companies in the  telecommunications  industry that are located  throughout  the
United States and considers all of its operations as one segment.

ILLUMINET has its corporate headquarters and a portion of its operations located
in Lacey, Washington, a network control center and related operations located in
Overland Park, Kansas, and additional SS7 Signal Transfer Points located in Rock
Hill,  South Carolina,  and Mattoon,  Illinois.  A new SS7 Signal Transfer Point
will be located in Las Vegas, Nevada and become operational in 1997.


Principles of Consolidation
- ---------------------------

The consolidated  financial  statements include the financial statements of USTN
Holdings, Inc. and its subsidiaries.  All significant  intercompany balances and
transactions have been eliminated in consolidation.

                                   -16-
<PAGE>
Cash Equivalents
- ----------------

ILLUMINET  considers all highly liquid  investments with original  maturities of
three  months  or less at  purchase  to be cash  equivalents.  Cash  equivalents
consist of money market funds that are stated at cost which approximates  market
value. At December 31, 1996 and 1995, such  investments  include  $9,538,536 and
$5,039,027,  respectively,  invested in a money market fund consisting of direct
obligations of the U.S.  Treasury and repurchase  agreements  collateralized  by
such obligations of the U.S. Treasury.

Accounts Receivable
- -------------------

One of ILLUMINET's services involves providing a clearinghouse function for toll
collected by telephone companies on behalf of other  telecommunications  service
providers.   At  December  31,  1996  and  1995,  accounts  receivable  included
$11,964,000  and  $9,779,000,  respectively,  of  such  toll  amounts  due  from
telephone companies,  and due to customers included $16,917,000 and $12,676,000,
respectively,  owed to such service  providers.  Accounts  receivable from these
companies  are  uncollateralized;  however,  uncollected  amounts  may be offset
against amounts otherwise due to service providers.

Concentration of credit risk with respect to trade receivables is limited due to
the diversity of the customer base and geographic dispersion and is evidenced by
a history of minimal customer account write-offs.

Property and Equipment and Capitalized Software
- -----------------------------------------------

Property and equipment and capitalized software are stated at cost. Depreciation
and amortization are provided using the straight-line  method over the estimated
useful lives of the assets.  Estimated  useful lives for property and  equipment
are as follows:

        Corporate  headquarters building 31.5 years Capitalized network costs 10
        years Office  equipment and systems 5 to 20 years Furniture and fixtures
        5 to 15 years  Computer  equipment  and software 3 to 5 years  Leasehold
        improvements 5 years

Computer   software   product  costs   represent  costs  incurred  for  software
development related to ILLUMINET's software products, which became available for
sale in 1995. Costs incurred after the technological feasibility of the
product was established have been capitalized. Costs incurred prior to that date
were  expensed.  For the years  ended  December  31,  1996 and  1995,  ILLUMINET
recognized  $561,000 and $101,000,  respectively,  of  amortization  expense for
computer software product costs. Capitalized computer software product costs are
amortized on a product-by-product basis. The annual amortization is equal to the
greater of the amount  computed  using (a) the ratio that current gross revenues
for a product bear to the total of current and anticipated future gross revenues
for that product,  or (b) the straight-line  method over the remaining estimated
economic life of the product.  Amortization starts when the product is available
for general release to customers.

                                        -17-
<PAGE>
ILLUMINET  evaluates the net realizable  value of capitalized  software based on
estimated  future  revenue and costs  associated  with the service for which the
software is utilized.

Revenue Recognition
- -------------------

ILLUMINET's  revenues are  recognized  when earned.  Computer  software  product
revenues are recognized  when all contractual  obligations  have been fulfilled.
Revenues are recorded net of amounts passed through to service providers.

Income Taxes
- ------------

ILLUMINET provides for income taxes under the liability method, whereby deferred
tax assets and liabilities are determined based on differences between financial
reporting and tax bases of assets and liabilities and are measured using enacted
tax rates and laws that will be in effect when the  differences  are expected to
reverse.

Earnings (Loss) Per Share
- -------------------------

Earnings  (loss) per share is  computed  using the  weighted  average  number of
common  shares and dilutive  common share  equivalents  outstanding  during each
period. Other potentially dilutive securities include USTN Holdings, Inc. Series
A Preferred Stock ("USTN Series A Preferred  Stock") and convertible  redeemable
subordinated  debentures,  which if dilutive, are included in the calculation of
fully diluted earnings (loss) per share.

Use of Estimates
- ----------------

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
reported  amounts of revenues and expenses during the reporting  period.  Actual
results could differ from these estimates.

Reclassifications
- -----------------

Certain  reclassifications  to the 1995 financial  statements  have been made to
conform to the 1996 presentation.

Note 2:  Acquisition and Corporate Realignment
- ----------------------------------------------

In exchange for the net assets of ITN, excluding U.S. Intelco's 36% ownership of
ITN on the  date  of the  Merger,  USTN  Holdings,  Inc.  issued  the  following
consideration and incurred the following costs:

    Fair value of USTN Common Stock issued  $5,561,778 Fair value of USTN Series
    A Preferred Stock issued 808,171 Direct and incremental merger costs 678,076
                                                            ---------
    Aggregate purchase price                               $7,048,025
                                                            =========

                                     -18-
<PAGE>
As  consideration  for  the  sale,   non-dissenting  ITN  shareholders  received
1,566,988  shares of USTN Holdings,  Inc. Common Stock ("USTN Common Stock") and
2,675 shares of USTN Series A Preferred  Stock. ITN Debentures were converted to
USTN convertible redeemable  subordinated  debentures ("USTN Debentures") having
the same  amount  of  outstanding  principal  and  interest  under the terms and
conditions  set forth in the Merger.  Payments  made to ITN  dissenters  totaled
$738,634 during the year ended December 31, 1996.

The aggregate  purchase price exceeded the fair value of the assets  acquired by
$2,506,548, and accordingly,  has been recorded as a reduction in the long-lived
assets.  The purchase price has been allocated to the acquired net assets of ITN
as of February 23, 1996, as follows:

          Cash                                            $  613,086

          Other current assets                               282,267
          Deferred tax assets                                991,644

In 1996, ILLUMINET paid dissenting U.S. Intelco shareholders a total of $183,229
in exchange for U.S.  Intelco stock held by such  dissenters on the merger date.
The payments were recorded as a stock repurchase and retirement transaction.

Assuming that this acquisition had taken place on January 1, 1995, unaudited pro
forma results of operations would have been as follows:

The pro forma  results do not  necessarily  represent  results  which would have
occurred if the acquisition had taken place on the dates indicated, nor are such
results necessarily indicative of the results of future operations.

In connection with the acquisition,  U.S. Intelco was substantially reorganized,
resulting in corporate realignment expenses totaling $350,067 and $1,077,590 for
the years ended December 31, 1996 and 1995,  respectively,  comprised  mainly of
severance costs.

Additional  borrowings  available  under the various note  agreements  with RTFC
aggregate  $5,188,007 at December 31, 1996.  All of the RTFC notes have variable
interest rates that are based on RTFCs short-term  funding costs. In accordance
with the  terms  of the  loan  agreements,  ILLUMINET  purchased  lender-issued,
non-interest-bearing  subordinated capital certificates based on a percentage of
the  gross  loan  amount.  Such  certificates  are  amortized  against  the loan
principal  balance  over  the  terms  of  the  respective  loans.   Certificates
purchased, net of amortization,  totaled $1,142,012 and $777,561 at December 31,
1996 and 1995,  respectively,  are  carried at cost,  and are  included in other
long-term  assets.  The loan  agreements  contain  certain  covenants,  the most
restrictive of which requires  ILLUMINET to maintain  certain cash  flow-to-debt
service ratios.

All RTFC loans are currently  secured by a first priority lien on  substantially
all of ILLUMINET's assets,  revenues and property,  excluding cash collected and
held on behalf of others in the normal course of providing ILLUMINET's services.
Cash and cash  equivalents  not subject to the mortgage lien were  $7,709,000 at
December 31, 1996.

In August,  1996, ILLUMINET entered into a secured line of credit agreement with
RTFC that  permits  ILLUMINET to borrow up to  $7,300,000,  not to exceed 80% of
accounts  receivable for a term of five years. The line of credit bears interest
at the lesser of the prime rate plus 1.5% or RTFC's monthly line of credit rate,
and contains certain covenants, the most restrictive of which requires ILLUMINET
to maintain a zero balance in the line at least five  consecutive  business days
every 360 days after the initial advance.  There were no borrowings  outstanding
against the line of credit at December 31, 1996.

The USTN  Debentures,  formerly ITN  Debentures  converted  in the Merger,  bear
interest  at 7.5% and are due August 15,  2001.  Interest on the  debentures  is
payable in quarterly installments,  in arrears.  Interest accrued for the period
prior to  December  31,  1995,  was  deferred  and will be paid  ratably on each
interest  payment  date  over the  remaining  term of the  debentures.  The USTN
Debentures are convertible  into the number of shares of USTN Common Stock equal
to the principal amount of the USTN Debenture at the time of conversion  divided
by the market price of USTN Common Stock at the time of  conversion  (as defined
in the  Indenture),  or if no market price exists,  on the basis of 90 shares of
USTN Common  Stock for each $1,000 in  principal  amount.  USTN  Debentures  are
subordinated to all senior debt.  USTN  Debentures are directly  associated with
USTN Series A Preferred Stock in that these securities were issued as a unit.

Maturities of the long-term debt for the years ending  December 31 are scheduled
as follows:

                  1997                 $2,174,850

Note 4:  Shareholders' Equity
- -----------------------------

At  December  31,  1996,  USTN  Holdings,  Inc.  is  authorized  to  issue up to
12,100,000  shares of capital stock consisting of (i) 12,000,000  shares of USTN
Common  Stock,  par  value  $.01 per  share,  and (ii)  100,000  shares  of USTN
Preferred Stock,  par value $.01 per share.  Each share of USTN Common Stock and
USTN  Series  A  Preferred  Stock  is  entitled  to  one  vote  and  100  votes,
respectively.

Each  share of USTN  Series A  Preferred  Stock will be  convertible  into 85.12
shares of USTN Common Stock ("Conversion  Amount"),  at the option of the holder
thereof at any time that the holder elects to convert a USTN Debenture issued as
a unit with such a share.  Each share of USTN Series A  Preferred  Stock will be
convertible,  at the option of USTN Holdings, Inc., into USTN Common Stock based
on the Conversion  Amount, at such time that the USTN Debenture issued as a unit
with such share is  converted  into  shares of USTN  Common  Stock.  If the USTN
Debentures and accrued interest  thereon,  and USTN Series A Preferred Stock had
been converted at December 31, 1996, 1,150,204 shares of USTN Common Stock would
have been issued.  In the event of  liquidation,  USTN Series A Preferred  Stock
will be  entitled to $1,000 per share out of the assets of  ILLUMINET  available
for distribution to its shareholders,  but before any payment or distribution is
made to holders of USTN Common Stock or any other  series of preferred  stock of
USTN Holdings, Inc.

Payments  of  dividends  are  restricted   under   ILLUMINET's   long-term  debt
arrangements,  as follows:  (1) approval of RTFC is required unless  ILLUMINET's
ratio of equity to total assets  exceeds 40% and (2) dividends are restricted to
75% of net income as defined in the indenture  relating to the USTN  Debentures.
Dividends are not payable to USTN Series A Preferred Stock unless  dividends are
declared, set aside or paid simultaneously to holders of USTN Common Stock.

ILLUMINET provides for deferred taxes based on the differences between the bases
of assets  and  liabilities  for  financial  reporting  purposes  and income tax
purposes,  calculated  using  enacted tax rates as of the balance sheet date. At
December 31, 1996 and 1995,  such  differences  primarily  related to the use of
accelerated depreciation and amortization for tax purposes, accruals for certain
expenses that are not currently  deductible for tax purposes until paid, the tax
basis of certain  investments that have been written-off for financial statement
purposes,  and software  development  costs that were  capitalized for financial
statement purposes. ILLUMINET has established a valuation reserve related to tax
benefits  associated  with  capital  losses  recorded  for  financial  statement
purposes  but not yet  realized  for tax  purposes,  unused net  operating  loss
carryforwards,  and other net  deferred  tax  assets due to the  uncertainty  of
ILLUMINET's future taxable income.

During the years ended December 31, 1996 and 1995,  ILLUMINET  redeemed  $23,248
and $84,765 respectively,  of lender-issued,  non-interest-bearing  subordinated
capital  certificates,  which were  deducted  from the mortgage  loan  principal
balance.

Note 7:  Employee Benefit Plans
- -------------------------------

ILLUMINET has qualified  profit  sharing/401(k)  retirement  plans  covering all
employees  subject  to  certain  eligibility  requirements.  ILLUMINET  provides
matching   contributions   to  the  plans'  trusts  on  a  portion  of  employee
contributions  to the plans,  and also may,  at the  discretion  of the board of
directors, provide a discretionary contribution. For 1996 and 1995, contribution
expense was approximately  $788,000 and $336,000,  respectively,  reflecting the
increase in employees covered by the plans as a result of the Merger.

Note 8:  Commitments and Contingencies
- --------------------------------------

ILLUMINET  assumed  non-cancelable  operating leases entered into by ITN for its
Rock  Hill,  Mattoon  and  Overland  Park  operating  facilities.   The  Mattoon
facilities are leased from one of ILLUMINET's corporate  shareholders,  formerly
an ITN shareholder, for a total of $38,000 for the period February 23, 1996, the
Merger date, to December 31, 1996.  The initial  leases for the Mattoon and Rock
Hill  facilities  expired  during  1996 and were  renewed for the first of three
five-year  optional  renewal  periods.  The lease for the Overland Park facility
expires August,  1998.  During the period February 23, 1996, the Merger date, to
December 31, 1996, ILLUMINET incurred rental costs of $321,000 on the leases.

Future  minimum lease  payments  under the  non-cancelable  leases for the years
ending December 31 are as follows:

                     1997                   $385,200

ILLUMINET is party to a contract  with the  subsidiary  of one of its  corporate
shareholders,  formerly  an  ITN  shareholder,  which  supplies  ILLUMINET  with
transmission  facilities  in the form of private  leased  lines.  Such lines are
leased from the corporate  shareholder  only if the arrangement is determined to
be the lowest  cost  after  completion  of a formal  bidding  process.  Payments

on the part of the ITN  board of  directors  related  to their  approval  of the
Merger into ILLUMINET.  In February,  1997, this suit was voluntarily  dismissed

Board of Directors and Shareholders
USTN Holdings, Inc.

We have audited the accompanying  consolidated  balance sheets of USTN Holdings,

statements of  operations,  shareholders'  equity,  and cash flows for the years
then  ended.  These  financial  statements  are  the  responsibility  of  USTN'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  USTN as of

                      U.S. TELNET HOLDINGS, INC.


     U.S. TELNET HOLDINGS, INC., a corporation organized and existing under

     No  holder of stock of the  Corporation  shall be  entitled  as such to any

and expressed in the resolution or  resolutions  providing for the issue of such
Preferred  Stock  from time to time  adopted  by the Board of  Directors  of the
Corporation pursuant to authority to do so which is hereby vested in the Board.
<PAGE>

Subdivision B. Common Stock.

     1. Dividends and Liquidation.  Subject to those rights expressly granted to
the holders of Preferred  Stock,  the holders of Common Stock shall have (a) the
right to receive  dividends,  when and as declared by the Board of  Directors of
the Corporation  out of the assets of the Corporation  available for the payment
of  dividends  under  the  laws of the  State  of  Delaware,  and (b)  upon  any
liquidation (complete or partial), dissolution or winding up of the Corporation,
whether voluntary or involuntary, the right to receive ratably all assets of the
Corporation remaining after the payment to the holders of Preferred Stock of any

of  Common  Stock  upon  such  liquidation,  dissolution  or  winding  up of the
Corporation, as provided in any Certificate of Designations, Powers, Preferences
and Rights of the Preferred Stock adopted by the Board of Directors, and subject
to any right the Preferred Stock may have to participate in the  distribution of

and Rights of the Preferred Stock.

     2.  Voting.  Each share of Common Stock shall entitle the holder thereof
to one vote, in person or by proxy, at any and all meetings of the
stockholders of the Corporation, on all propositions before such meetings.

     FIFTH:  The name and address of the Incorporator is as follows:

               Name                    Address

          Michael B. Fischer       Rudnick & Wolfe
                                   203 N. LaSalle St., Suite 1800
                                   Chicago, Illinois 60601

     SIXTH:  The number of directors of the Corporation  which shall  constitute
the entire Board shall initially be sixteen (16), but such number may be changed
from time to time to a number not less than five (5) nor more than  sixteen (16)
by resolution adopted by a majority of the entire Board; provided, however, that
the number of directors  constituting the entire Board shall not be decreased by
the Board of  Directors  below the number then in office  unless  such  decrease
shall become effective at any annual meeting of stockholders to the extent terms
of office are then expiring. As used in this Article SIXTH, "entire Board" means
the total number of directors which the Corporation  would have if there were no
vacancies.  Any director or directors  may be removed from office only for cause
and only by the  vote of  eighty  percent(80%)  of the  voting  power of all the
shares of capital stock of the  Corporation  then entitled to vote  generally in
the election of directors, voting together as a single class. Any vacancy on the
Board of Directors that

<PAGE>
results for any reason, including an increase in the number of directors, may be
filled by the affirmative vote of a majority of the directors then in office.

     SEVENTH:  Any of the following actions must be approved by the holders of
two-thirds of the outstanding shares of stock entitled to vote thereon:

          (a) a plan of merger  in which the  Corporation  merges  into  another
     corporation  or in  which  one or more  corporations  (other  than  solvent
     corporations at least 90% of the  outstanding  share of each class of which
     are owned by the  Corporation)  merge  into the  Corporation,  or a plan of
     consolidation  with one or more  corporations  or a plan of mandatory share
     exchange with another corporation;

          (b)  a  sale,  lease,   exchange  or  other  disposition  of  all,  or
     substantially  all,  of the  Corporation's  property  and  assets,  with or
     without  goodwill,  if not made in the  usual  and  regular  course  of the
     Corporation's business; and

          (c)  the voluntary dissolution of the Corporation.

     EIGHTH:  The following provisions are inserted for management of the
business and conduct of the affairs of the Corporation and to define and
regulate the powers of the Corporation, the directors and the stockholders:

          (a)  Election of directors need not be by written ballot unless the
     by-laws so provide.

          (b) The Board of Directors of the Corporation shall have power without
     the assent or vote of the stockholders to make, alter,  amend,  change, add
     to or repeal the by-laws of the corporation;  to fix and vary the amount of
     capital stock or cash to be reserved for any proper  purpose;  to authorize
     and cause to be  executed  mortgages  and liens upon all or any part of the
     property of the  Corporation;  to determine the use and  disposition of any
     surplus or net profits; and to fix the times for
     the declaration and payment of dividends.

<PAGE>


          (c) The directors in their  discretion  may submit any contract or act
     for approval or ratification  at any annual meeting of the  stockholders or
     at any meeting of the  stockholders  called for the purpose of  considering
     any such act or contract, and any contract or act that shall be approved or
     be  ratified  by the vote of the  holders of a majority of the stock of the
     Corporation  which is represented in person or by proxy at such meeting and
     entitled to vote there at (provided that a lawful quorum of stockholders be
     there  represented  in person or by proxy) shall be as valid and as binding
     upon the  Corporation  and upon all the  stockholders as though it had been
     approved or ratified by every  stockholder of the  Corporation,  whether or
     not the contract or act would  otherwise be open to legal attack because of
     directors' interest, or for any other reason.

          (d) In  addition  to the powers  and  authorities  hereinbefore  or by
     statute  expressly  conferred upon them, the directors are hereby empowered
     to  exercise  all such  powers  and do all such  acts and  things as may be
     exercised or done by the Corporation; subject, nevertheless, to the
     provisions  of the statutes of  Delaware,  of this  Certificate  and to any
     by-laws from time to time made by the stockholders;  provided however, that
     no by-laws so made shall  invalidate  any prior act of the directors  which
     would have been valid if such by-law had not been made.
<PAGE>

     NINTH: The Corporation  shall to the full extent provided by Section 145 of
the Delaware General  Corporation  Law, as amended from time to time,  indemnify
all persons whom it may indemnify pursuant thereto.

     TENTH:  Whenever a  compromise  or  arrangement  is  proposed  between  the
Corporation  and  its  creditors  or  any  class  of  them  and/or  between  the
Corporation  and its  stockholders  or any class of them, any court of equitable
jurisdiction  within the State of Delaware may, on the  application in a summary
way of the  Corporation  or of any  creditor  or  stockholder  thereof or on the
application of any receiver or receivers appointed for the Corporation under the
provisions of Section 291 of Title 8 of the Delaware Code or on the  application
of trustees in  dissolution  or of any receiver or receivers  appointed  for the
Corporation under the Provisions of Section 279 of Title 8 of the Delaware Code,
order  a  meeting  of  the  creditors  or  class  of  creditors,  and/or  of the
stockholders or class of stockholders of the Corporation, as the case may be, to
be  summoned  in such  manner  as the court  directs.  If a  majority  in number
representing  three-fourths  in value of the  creditors  or class of  creditors,
and/or of the stockholders or class of stockholders of the  Corporation,  as the
case may be, agree to any compromise or arrangement and to any reorganization of
the  Corporation  as  consequence of such  compromise or  arrangement,  the said
compromise or arrangement  and the said  reorganization  shall, if sanctioned by
the court to which the said  application  has been  made,  be binding on all the
creditors  or class of  creditors,  and/or on all the  stockholders  or class of
stockholders,  of  the  Corporation,  as  the  case  may  be,  and  also  on the
Corporation.
<PAGE>

     ELEVENTH: The Corporation reserves the right to amend, alter, change or
repeal any of the provisions  contained in its certificate of  incorporation  in
the manner now or hereafter  prescribed by statute,  and all rights conferred on
officers,  directors  and  stockholders  herein  are  granted  subject  to  this
reservation;  provided,  that the  affirmative  vote of the holders of record of
outstanding shares representing at least two-thirds (2/3rds) of the voting power
of all of the shares of capital stock of the  Corporation  then entitled to vote
generally, voting together as a single class, shall be required to amend, alter,
change or repeal  any  provision  of, or to adopt any  provision  or  provisions
inconsistent   with  Articles   SIXTH  and  SEVENTH  of  this   Certificate   of
Incorporation.

     TWELFTH:  No director of the Corporation  shall be personally liable to the
Corporation  or its  stockholders  for monetary  damages for breach of fiduciary
duty by such  director  as a  director;  provided,  however,  that this  Article
TWELFTH  shall not  eliminate or limit the liability of a director to the extent
provided by applicable law (i) for any breach of the director's  duty of loyalty
to the Corporation or its  stockholders,  (ii) for acts or omissions not in good
faith or which involve  intentional  misconduct  or a knowing  violation of law,
(iii) under Section 174 of the General Corporation Law of the State of Delaware,
or (iv) for any transaction from which the director derives an improper personal
benefit.  No amendment to or repeal of this  Article  TWELFTH  shall apply to or
have any effect on the liability or alleged  liability of any director of the
Corporation for or with respect to any acts or omissions  of such  director and 
occurring  prior to such  amendment or repeal.  If the  Delaware  General  
Corporation  Law  is  amended  to  authorize corporate  action  further  
eliminating  or limiting the  personal  liability of directors,  then  the 
liability  of a  director  of the  Corporation  shall  be eliminated or limited 
to the fullest  extent  permitted by the Delaware  General Corporation Law, as 
so amended.

     IN WITNESS WHEREOF, I have hereunto set my hand and seal.


DATED: August 2, 1995.

<PAGE>

     SECOND SUPPLEMENTAL INDENTURE, dated as of June 24, 1996 (the "Supplemental
Indenture"),  between USTN HOLDINGS, INC., a Delaware corporation  ("Holdings"),
USTN SERVICES,  INC., a Delaware  corporation  ("Services"),  and UMB BANK, N.A.
(f/k/a United Missouri Bank, N.A.), as Trustee (the "Trustee"),  to an Indenture
dated as of August 15, 1991,  between  Independent  Telecommunications  Network,
Inc. and the Trustee.

     WHEREAS, Section 2.6 of the Indenture provides that the Securities may only
be  sold  or  otherwise  transferred  together  with  the  shares  of  Series  A
Convertible  Preferred  Stock (the  "Series A Stock")  issued as a unit with the
Securities; and

     WHEREAS, the Trustee, Holdings and Services desire to permit holders of the
Securities  to transfer  the  Securities  without the Series A Stock issued as a
unit with such  Securities when the separation of the Securities from the Series
A Stock resulted from an involuntary event; and

     WHEREAS,  Section  2.6 of the  Indenture  does not  adequately  address the
situation when the occurrence of an involuntary  event results in the separation
of the Securities from the Series A Stock; and

     WHEREAS, Section 9.1 of the Indenture permits an amendment of the Indenture
without  the  consent of any  Securityholder  to cure any  ambiguity,  defect or
inconsistency in the Indenture; and

     WHEREAS, all acts and things necessary to make this Supplemental Indenture,
when duly  executed and  delivered,  a valid,  binding and legal  instrument  in
accordance with its terms and for the purposes herein expressed,  have been done
and  performed by the parties  hereto;  and the  execution  and delivery of this
Supplemental Indenture have been in all respects duly
authorized by said parties;

     NOW, THEREFORE,  in consideration of the premises and other  consideration,
the receipt of which is hereby acknowledged,  the Trustee, Holdings and Services
mutually  covenant  and agree,  for the equal and  proportionate  benefit of the
respective Holders from time to time of the Securities, as follows:

                                  ARTICLE I

                                 DEFINITIONS

     The third  paragraph of Section 2.6 of the Indenture is hereby  deleted and
replaced in its entirety with the following language:
<PAGE>
     "The  Securities  may only be sold or otherwise  transferred as a unit with
the  Series A Stock  issued as a unit with the  Securities;  PROVIDED,  HOWEVER,
that, if Securities  held by a  Securityholder  are separated  from the Series A
Stock  due  to the  redemption  of the  Series  A  Stock  by  the  Company,  the
cancellation  of Series A Stock by  operation  of law or the  occurrence  of any
event that is  involuntary on the part of the  Securityholder  (as determined by
Holdings and Services in their discretion),  then such  Securityholder  (and any
transferee of the  Securities)  shall be permitted to transfer  such  Securities
without the Series A Stock  issued as a unit with such  Securities  upon written
notice to the Trustee,  Holdings and Services." Prior to the  authentication  of
any  Security,  the Company and Holdings  shall provide the Trustee with written
certification of the transferability of such Security pursuant to this Section.

                                   ARTICLE II

                                   THE TRUSTEE

     The Trustee shall not be  responsible in any manner  whatsoever  for, or in
respect of, the validity or  sufficiency of this  Supplemental  Indenture or the
due  execution  hereof by  Holdings or  Services,  or for, or in respect of, the

conditions  set  forth in the  Indenture,  as fully  to all  intents  as if this

                            USTN HOLDINGS, INC.


Pursuant to Section 151 of the Delaware General Corporation Law

1.   DESIGNATION

     The designation of the series of Preferred Stock created by this Resolution
     shall be the Series A Convertible  Preferred Stock (hereinafter called this
     "Series")  and the  number  of  shares  constituting  this  Series  is Four
     Thousand Four Hundred and Sixteen (4,416).

2.   DIVIDENDS

     Dividends  shall be  declared,  set aside and paid on this Series only upon
     resolution of the Board of Directors of the  Corporation;  provided that no
     dividends  may be  declared,  set  aside  or  paid on  this  Series  unless
     dividends are declared,  set aside or paid simultaneously to holders of the
     common stock of the Corporation.


3.   LIQUIDATION PREFERENCE

     In the event of  voluntary  or  involuntary  liquidation,  dissolution,  or
     winding-up of the affairs of the Corporation,  whether complete or partial,
     the  holders of the shares of this  Series  shall be  entitled to and shall
     receive total cash payments equal to One Thousand  Dollars  ($1,000.00) per
     share  (the  "Liquidation  Preference  Amount")  out of the  assets  of the
     Corporation available for distribution to its stockholders,  but before any
     payment  or  distribution  is made to  holders  of the shares of the common
     stock or of any other series of preferred stock of the Corporation. If upon
     the  occurrence  of such event the assets and  property  to be  distributed
     among the  holders  of this  Series,  shall be  insufficient  to permit the
     payment to such holders of this Series of the full  Liquidation  Preference
     Amount,  then the entire  remaining  assets and property of the Corporation
     legally available for distribution  shall be distributed  ratably among the
     holders of this Series.

4.   VOTING RIGHTS

     The holders of shares of this Series shall be entitled to one hundred (100)
     votes per share with respect to all matters  submitted to the Corporation's
     shareholders  for  decision  and will be entitled to vote  separately  as a
     Series with respect to the approval of the sale,  lease,  exchange or other
     disposition of all or substantially all of the  Corporation's  property and
     assets,  or the merger or consolidation of the Corporation with or into any
     other corporation or entity, if such approval is required by law.

5.   CONVERSION

    (a)  Each share of this Series shall be convertible into 85.12 shares of the
         common  stock,  $.01 par value,  of the  Corporation  (the  "Conversion
         Amount"),  at the  option of the  holder  thereof  at any time that the
         holder   elects  to  convert   the   Corporation's   7.5%   Convertible
         Subordinated Debenture due August 15, 2001 (the "Debenture") issued
         as a unit with such share.

    (b)  Each share of this Series  shall be  convertible,  at the option of the
         Corporation, into the Conversion Amount, at any time that the Debenture
         issued as a unit with such  share is  converted  into  shares of common
         stock, $.01 par value, of the Corporation.

    (c)  In  the  event  the  corporation   shall  at  any  time  subdivide  the
         outstanding  shares of common stock, or shall issue a stock dividend on
         its  outstanding   common  stock,   the  Conversion   Amount  shall  be
         proportionately  increased,  and in case the  Corporation  shall at any
         time combine the outstanding shares of common stock, the Conversion


<PAGE>



         Amount  in  effect  immediately  prior  to such  combination  shall  be
         proportionately  decreased,  effective  at the close of business on the
         date of such subdivision,  dividend or combination, as the case may be.
         In the  event  the  Corporation  merges  or  otherwise  reorganizes  or
         consolidates with any other corporation or corporations,  the holder of
         any  share of this  Series  shall  have the right to  receive  from any
         surviving  corporation  preferred stock with the same or  substantially
         identical  rights,  privileges  and  preferences  as the shares of this
         Series;  provided,  however,  that an  aggregate of  two-thirds  of the
         holders of this Series may elect not to receive  such  preferred  stock
         from the surviving corporation, in which case no holders of this Series
         shall be entitled to receive such preferred stock.

    (d)  The holder of any share of this Series may exercise the conversion
         rights as to such share by delivering to the Corporation during
         regular business hours, at the principal office of the Corporation,
         the certificate or certificates for the shares to be converted, duly
         endorsed for transfer to the Corporation (if required by the
         Corporation), and accompanied by written notice stating that the
         holder elects to convert such shares. Conversion shall be deemed to
         have been effective on the date when such delivery is made, and
         such date is referred to herein as the Conversion Date.  As promptly
         as practicable thereafter, the Corporation shall issue and deliver to
         or upon the written order of such holder, at such office, a
         certificate or certificates for the number of shares of common stock
         to which such holder is entitled.  The holder shall be deemed to have
         become a shareholder of common stock of record on the applicable
         Conversion bate unless the transfer books of the Corporation are
         closed on that date, in which event such holder shall be deemed to
         have become a shareholder of common stock of record on the next
         succeeding date on which the transfer books are open.

    (e)  In the event the Corporation elects to exercise its right to convert
         any shares of this Series pursuant to paragraph (b) above, the
         Corporation shall notify the holder of such shares of the
         Corporation's election to convert and the number of shares to be
         converted.  Upon receipt of such notice the holder shall deliver to
         the Corporation during regular business hours, at the principal
         office of the Corporation, their certificate or certificates for the
         shares to be converted, duly endorsed for transfer to the Corporation
         (if required by the Corporation).  As promptly as practicable
         thereafter, the Corporation shall issue and deliver to such holder a
         certificate or certificates for the number of shares of common stock
         to which such holder is entitled.  The shares of this Series shall he
         deemed converted as of the mailing of the notice of conversion,
         however, such holder shall not be deemed to have become a shareholder
         of common stock of record until his certificate or certificates for
         the shares to be converted have been delivered to the Corporation.
         The holder shall be deemed to have become a shareholder of common
         stock of record on such delivery date unless the transfer books of
         the Corporation are closed on that date; in which event such holder
         shall be deemed to have become a shareholder of common stock of
         record on the next succeeding date on which the transfer books are
         open.

    (f)  The Corporation  shall at all times reserve and keep available,  out of

                         CALCULATION OF BONUS AMOUNTS

Section 2.01 Committee Designations.

     (a)  The Committee  shall meet  before  the  beginning  of each Performance
          Measurement Period and designate:

     (1)  The name of each Participant.

     (2)  The Performance Measurement Areas either for the Plan as a whole or an

          Measurement Period;

     (3)  The  percentage  of Base  Salary  to which the  Stretch  Point and the

          shall be  evaluated  in  determining  what the  total  Bonus  for each
          Participant shall be.

Section  2.02   Calculation  of  Bonus.  The  Committee  shall  determine  which
established performance criteria have been achieved by each Participant, whether
a  Participant  has achieved the Stretch Point or Target Point for any criteria,
and the  calculation  of the Bonus  pursuant to the formula  designated for each
Participant.  This  will  occur  90 days  after  the  close  of the  Performance
Measurement Period (fiscal year).

In no event  will any bonus be earned or  payable  under  this Plan  unless  the
Company's  earnings  before  interest,  taxes,  depreciation,  and  amortization
(EBITDA)  equals  at  least  80%  of  the  Company's  budgeted  EBITDA  for  the
Performance Measurement Period.

Section 2.03 Election.  Each  participant  may make an irrevocable  election for
his/her  Bonus  for any  Performance  Measurement  Period  to be paid in Cash or
Shares.

An annual  valuation of the Company's  shares will be conducted by the committee
and all  Plan  Participants  will be  notified  in  writing  of such  valuation.
Participant's  payment  election  will be required  within 10  business  days of
receipt of the valuation notice.

If a Participant  elects to have the Bonus paid in Shares,  the number of Shares
credited to a Participant's  account pursuant to Article 111 shall be the amount
of the Bonus divided by (i) the closing sale price of the Company's common stock
on the first trading day of that Performance  Measurement  Period as reported by
the  NASDAQ  Stock  Market  or, if the  common  stock is  traded  on a  national
securities  exchange then as reported by that exchange or (ii) if the Shares are
not publicly traded, the value per Share as determined by a market
price  valuation  as of the  beginning  of the  Performance  Measurement  Period
performed  by an  independent  third  party  approved by the Board or if no such
valuation has been  performed  within the preceding  15-month  period,  then the
value per Share  shall be  determined  by the Board as of the  beginning  of the
Performance  Measurement  Period. If no election is made, the Bonus will be paid
in cash.

Section 2.04 Mid-Period  Termination.  In the event a  Participant's  employment
terminates prior to the end of a Performance Measurement Period, other than in a
manner  resulting in a forfeiture under Section 3.06, such  Participant's  Bonus
shall be  calculated  based on the  results  of the Bonus  calculation  for that
Participant through such date of termination, extrapolated to a full Performance
Measurement  Period basis,  and then prorated for the portion of the Performance
Measurement  Period prior to  termination.  Such prorated Bonus shall be paid in
accordance with the terms of Section 3.01.

                                   ARTICLE III

                        PAYMENT OF BONUS AND FORFEITURES

Bonuses  shall  be  calculated  and  credited  to a  Participant's  account,  as
described in Section 3.02. Bonuses will be paid no later than the 90th day after
the date on which the  Participant  becomes vested under Section 3.05.  Interest
will begin to accrue from the close of the Performance Measurement Period of the
Long Term Plan, at the actual rate, if any, earned on the company's cash account
at it's primary financial institution.

Section 3.02  Participant  Account.  The Committee  shall cause an account to be
kept in the name of each  Participant and each  Beneficiary  which shall reflect

the Plan.

Section 3.03 Contingent  Interest.  Until and except to the extent that deferred
benefits  hereunder  are  distributed  to  or  vested  in  the  Participants  or
Beneficiaries  from time to time in  accordance  with this Plan or orders of the
Committee,   the  interest  of  each  Participant  and  Beneficiary  therein  is
contingent only and is subject to forfeiture as provided in Section 3.05.  Title
to and beneficial  ownership of any assets,  whether cash or investments,  which
the Company may set aside or earmark to meet its  contingent or vested  deferred
obligations hereunder,  shall at all times remain in the Company; no Participant
or Beneficiary  shall under any  circumstances  acquire any property interest in
any  specific  assets of the Company;  and no assets shall secure the  Company's
obligations hereunder.

Section 3.04  Beneficiaries.  Each Participant shall have the right to designate
Beneficiaries  who are to  succeed  to his or her  contingent  right to  receive
future  payments  hereunder  in the event of his or her death by delivery to the
Committee of a Beneficiary Designation Form. In case of a failure of designation
or the  death  of a  designated  Beneficiary  without  a  designated  successor,
distribution shall be made to the Participant's estate.

          the end of the Performance Period.

          unvested payments  hereunder shall be forfeited upon the occurrence of
          any one or more of the following events:

         (1)  if the Participant is discharged for Cause (as defined in
              Section 3.05(e)) from employment by the Company or a Subsidiary;
              or

         (2)  if the Participant shall voluntarily terminate employment with
              the Company.

     (c)  Upon death,  disability or termination from employment  without Cause,
          all amounts in a Participant's  account shall  immediately vest and be
          non-forfeitable,  and shall be paid  within 90 days after such  death,
          disability, or termination without cause.

     (d)  The  Committee  may at any time and from time to time order all or any
          part  of the  value  of  the  contingent  right  of a  Participant  or
          Beneficiary  to  receive  future  payments  to be vested and no longer
          subject to forfeiture,  and may order payment of the amounts so vested
          on dates specified in such orders, if it finds such action appropriate
          under the circumstances.

     (e)  "Cause" means any one of the following:

          (1)  Indictment  or  conviction  of a  crime  which  in the  sole  and
               absolute  discretion  of  the  Board  reflects  adversely  on the
               Company's public image; or

          (2)  Failure to perform in a manner satisfactory to the Board the
               duties and responsibilities of the Participant's position; or

          (3)  Any breach of the Participant's fiduciary duty to the Company
               deemed significant by the Board in its sole and absolute
               discretion; or

          (4)  The Board determines that a material breach by the Participant of
               any written employment  agreement he may have with the Company or
               a Subsidiary has occurred.

Section 3.06 Change in Control.  No forfeiture  under Section  3.05(b)(2)  shall
occur in the event a Participant  voluntarily  terminates employment between the
time that a Change in Control occurs and the end of the fiscal year within which
such  Change  in  Control  occurs.  A  Change  in  Control  shall  mean  (i) the
acquisition  by a third party not currently a shareholder  of the Company of 30%
or more of the voting power of the Company;  (ii) the merger or consolidation of
the Company with  another  entity and the Company is not the  surviving  entity;
(iii) the sale of  substantially  all of the assets of the Company,  or (iv) any
other event which the Board  determines  constitutes  a change in control of the
Company.

Section 4.01 Books and Records; Expenses. The books and records to be maintained
for the purpose of the Plan shall be maintained by the officers and employees of
the Company at its expense  and  subject to the  supervision  and control of the

from the  general  funds of the  Company  and shall not be charged  against  any
Participant account.

Section  4.02  Attachment.  To the  extent  permitted  by law,  the right of any
Participant or any Beneficiary in any benefit or to any payment  hereunder shall
not be subject in any manner to  attachment or other legal process for the debts
of such Participant or Beneficiary; and any such benefit or payment shall not be
subject to anticipation, alienation, sale, transfer, assignment or encumbrance.

Section 4.03 No Fiduciary Relationship. Nothing contained herein shall be deemed
to  create a trust of any  kind or  create  any  fiduciary  relationship.  Funds
invested  hereunder  shall continue for all purposes to be a part of the general
funds of the Company,  and no person other than the Company shall,  by virtue of
the provisions of this Plan, have any interest in such funds. To the extent that
any person  acquires a right to receive  payments  from the  Company  under this
Plan,  such right shall be no greater  than the right of any  unsecured  general
creditor of the Company.

Section 4.04 No  Liability.  No member of the Board or of the  Committee  and no
officer or employee of the Company  shall be liable to any person for any action
taken or omitted  in  connection  with the  administration  of this Plan  unless
attributable  to his own fraud or willful  misconduct;  nor shall the Company be
liable to any person for any such action unless attributable to fraud or willful
misconduct on the part of a director, officer or employee of the Company.

time by the  Board  of  Directors  of the  Company.  In the  event  the  Plan is
terminated  or amended in such a way as to eliminate a Bonus for any  particular
Participant during the course of a Performance  Measurement Period, all Bonuses,
if any, for such Participants shall nevertheless be determined at the end of the
Performance  Measurement  Period,  but shall be prorated  for the period of time
prior to such amendment or termination, and shall be paid in accordance with the
terms of this Plan.

notice  and a copy  of  every  amendment  shall  be  given  in  writing  to each
Participant.

be deemed to give any Participant the right to be retained in the service of
the  Company or to  interfere  with the right of the  Company to  discharge  any
Participant,  for or without Cause, at any time,  regardless of the effect which
such discharge shall have upon such individual as a Participant in the Plan.

Section 5.04 Governing Law.  This plan shall be construed in accordance with
the laws of the State of Washington.

Section 5.05  Interpretation of Plan. The Committee shall have sole and absolute
discretion and authority to interpret all provisions of this Plan and to resolve

shall receive any payments pursuant to this Plan, and the amount of any payments

so comply,  it shall be deemed null and void, to the extent permitted by law and
deemed advisable by the Committee.

Section  5.08  Taxes:  Withholding,.  In the  event  a  Participant  receives  a
distribution  of  Shares  as  payment  of  a  Bonus  which  is  taxable  to  the
Participant, the taxable amount will be based on the fair value of the Shares at
the time of  payment.  In order to pay any  applicable  federal,  local or state
income taxes on such  distribution,  the Participant may request the Company (i)
to convert a portion  of the  Shares  then  being  distributed  to cash,  at the
valuation  of those  Shares  as  determined  by the Board as of the date of such
conversion;  or (ii) to withhold a specified amount from other cash compensation
which the Participant may receive.

               Section 3.04(d)) from employment by the Company or a
               Subsidiary;

          (2)  if the Participant shall voluntarily terminate employment with
               the Company.
<PAGE>
     (b)  The  Committee  may at any time and from time to time order all or any
          part  of the  value  of  the  contingent  right  of a  Participant  or
          Beneficiary  to receive a Bonus to be vested and no longer  subject to
          forfeiture,  and may order  payment of the  amounts so vested on dates
          specified in such orders,  if it finds such action  appropriate in the
          circumstances.

     (c)  Upon death,  disability or termination from employment  without Cause,
          all Bonus amounts due to a  Participant  for the portion of the fiscal
          year prior to such event shall immediately vest and be on-forfeitable,
          and shall be paid in accordance with Section 3.01.

     (d)  "Cause" means any one of the following:

           (1)  Indictment  or  conviction  of a crime  which  in the  sole  and
                absolute  discretion  of the  Board  reflects  adversely  on the
                Company's public image; or

           (2)  Failure to perform in a manner satisfactory to the Board the
                duties and responsibilities of the Participant

           (3)  Any breach of the Participant's fiduciary duty to the Company
                deemed significant by the Board in its sole and absolute
                discretion; or

           (4)  The Board  determines  that a material breach by the Participant
                of any written employment agreement he may have with the Company
                or a Subsidiary has occurred.

Section 3.05 No Fiduciary Relationship. Nothing contained herein shall be deemed
to  create a trust of any kind or  create  any  fiduciary  relationship.  To the
extent  that any person  acquires a right to receive  payments  from the Company
under this Plan,  such right shall be no greater than the right of any unsecured
general creditor of the Company.

Section  3.06  Change  in  Control.  In  the  event  a  Participant  voluntarily
terminates  employment  between the time that a Change in Control  occurs,  such
Participant shall not be entitled to receive any Bonus under this Plan. A Change
in Control  shall mean (i) the  acquisition  by a third  party not  currently  a
shareholder  of the Company of 30% or more of the voting  power of the  Company;
(ii) the merger or  consolidation  of the Company  with  another  entity and the
Company is not the surviving entity;  (iii) the sale of substantially all of the
assets of the  Company,  or (iv) any  other  event  which  the Board  determines
constitutes a change in control of the Company.

with the terms of this Plan.

Section 5.02 Notice.  Notice of every such amendment shall be given in writing
to each Participant.

Section 5.03 No Guarantee of Employment. Nothing contained in this Plan shall be
deemed to give any  Participant  the right to be  retained in the service of the
Company  or to  interfere  with  the  right  of the  Company  to  discharge  any
Participant,  for or without Cause, at any time,  regardless of the effect which
such discharge shall have upon such individual as a Participant in the Plan.

Section 5.04 Governing Law.  This Plan shall be construed in accordance with
the laws of the State of Kansas.

Section 5.05  Interpretation of Plan. The Committee shall have sole and absolute
discretion and authority to interpret all provisions of this Plan and to resolve
all  questions  arising  under  this  Plan;  including,   but  not  limited  to,
determining  whether any person is eligible under this Plan,  whether any person
shall receive any payments pursuant to this Plan, and the amount of any payments
to be made  pursuant  to this Plan.  Any  interpretation,  resolution  or 
determination of the Committee shall be final and binding upon all concerned and

ITEM 8:   CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON
          ACCOUNTING AND FINANCIAL DISCLOSURE

Effective  September 12, 1995, U.S. Intelco engaged,  upon approval of its Board
of  Directors,  Ernst & Young LLP to  perform  an audit of, and issue its report
with  respect to U.S.  Intelco's  December  31,  1994  financial  statements  in
response to Coopers & Lybrand  L.L.P.  ("Coopers &  Lybrand")  confirmation,  by
letter dated September 5, 1995, to U.S. Intelco that it would not consent to the
inclusion in the Merger related Proxy  Statement/Prospectus of its report on the
U.S. Intelco Financial Statements for the years ended December 31, 1994 and 1993
(which report appeared in U.S. Intelco's Special Financial Report filed with the
Securities and Exchange  Commission pursuant to Rule 15d- 2 under the Securities
Exchange  Act of 1934).  Such  report of Coopers & Lybrand  did not  contain any
adverse opinion or disclaimer of opinion, nor was it modified as to uncertainty,
audit scope or accounting principles.  Since January 1, 1993, there have been no
disagreements  between  U.S.  Intelco  and  Coopers & Lybrand  on any  matter of
accounting  principles or practices,  financial statement disclosure or auditing
scope or procedure.  A letter from Coopers & Lybrand stating that it agrees with
the  statements  made by USTN Holding,  Inc. in this paragraph is included as an
exhibit hereto.
