                                    PART I

Item 1.  Description of Business
- ------   -----------------------

     (a) General Development of Business:
         ------------------------------- 

     North Pittsburgh Systems, Inc. (the Registrant), organized May 31, 1985, is
a holding company and has no operating function.  Its predecessor, North
Pittsburgh Telephone Company (North Pittsburgh or NPTC), a telephone public
utility incorporated in 1906, became a wholly-owned subsidiary of the Registrant
on May 31, 1985.  Penn Telecom, Inc. (Penn Telecom) became a wholly-owned
subsidiary of the Registrant on January 30, 1988.  Prior to this date, Penn
Telecom was a wholly-owned subsidiary of North Pittsburgh.  The principal
business activities of Penn Telecom consist of the sale, rental and servicing of
telecommunication equipment to end users, the resale of bulk billed message toll
services and high capacity intercity facilities.  Penn Telecom has recently been
certificated as a Competitive Access Provider and has entered into this
business.  Pinnatech, Inc. (Pinnatech), a wholly-owned subsidiary of the
Registrant formed in 1995, provides Internet access services. Management
Consulting Solutions, Inc. (MCSI), formed in 1995, was sold on July 31, 1997.
MCSI provided consulting and computer outsourcing services to healthcare and
other industries.  The Registrant, NPTC, Penn Telecom and Pinnatech operate
under the provisions of the Pennsylvania Business Corporation Law.  Other than
the sale of MCSI, no significant changes in the mode of conducting business by
the Registrant or its subsidiaries have occurred since the beginning of the
fiscal year ended December 31, 1997.

     (b) Financial Information About Industry Segments:
         --------------------------------------------- 

     This paragraph is not applicable.  The Registrant, through North Pittsburgh
and Penn Telecom, is engaged in the business of providing telecommunication
services and equipment which is not considered separable into industry segments.
The business activities of Pinnatech, to date, are not considered significant
and are not reportable as an industry segment of the Registrant.

     (c) Narrative Description of Business:
         --------------------------------- 

     (1) Business Done and Intended To Be Done:
         ------------------------------------- 

          (i)  Principal Services Rendered.
               --------------------------- 

          The Registrant, through North Pittsburgh and Penn Telecom, is engaged
in providing the following telecommunication services and equipment to customers
generally located in Western Pennsylvania:

          Local Network Services.  North Pittsburgh furnishes wireline
          -----------------------                                     
telecommunication services in parts of Allegheny, Armstrong, Butler and
Westmoreland Counties subject to the jurisdiction of the Pennsylvania Public
Utility Commission (PA PUC) under the provisions of the Pennsylvania Public
Utility Code which confers upon that Commission broad powers of supervision and
regulation over public utilities with respect to service and facilities, rates
and charges, securities, the encumbering or disposition of public

                                       1
<PAGE>
 
utility properties, accounting and various other matters.  At January 31, 1998,
North Pittsburgh served approximately 66,600 customers through its digital
fiber-linked central offices.

     The Telecommunications Act of 1996 (the 1996 Act) prohibits state
legislative or regulatory restrictions or barriers to entry regarding the
provision of local telephone service. It also requires most incumbent local
exchange carriers to interconnect with the networks of other telecommunications
carriers, unbundle their services into network elements, offer their
telecommunications services at wholesale rates to allow the resale of such
services and allow other telecommunications carriers to locate equipment on
their premises.  Local exchange telephone carriers are also required to
compensate each other for the transport and termination of calls.

     North Pittsburgh's wireline operations are considered Rural under the 1996
Act and are exempt from certain of the foregoing obligations unless, in response
to a bona fide request for interconnection, the PA PUC removes that exemption.
North Pittsburgh along with 17 other rural companies in Pennsylvania was granted
a temporary suspension for a two-year period of the interconnection requirements
outlined in the 1996 Act.

     North Pittsburgh is currently under rate base rate-of-return (ROR)
regulation within the intrastate jurisdiction.  However, under PA PUC Chapter 30
rules, North Pittsburgh is required to develop and file a Network Modernization
Plan prior to July 8, 1998 that commits North Pittsburgh to providing broadband
service capability throughout its service area or be subject to a show cause
order for failure to do so.  North Pittsburgh, as part of this filing, may seek
approval of an alternative form of regulation from the PA PUC, such as price cap
regulation.

     Historically, North Pittsburgh's wireline operations have not experienced
significant competition in its franchised service area.  As a result of the
passage of the 1996 Act, North Pittsburgh's local wireline operations is
experiencing increased competition from various sources, including, but not
limited to, resellers of their local exchange services, large end users
installing their own networks, Interexchange Carriers (IXCs), satellite
transmission services, cellular communications providers, cable television
companies, radio-based personal communications companies, Competitive Access
Providers (CAPs) and other systems capable of completely or partially bypassing
local telephone facilities. North Pittsburgh cannot predict the specific effects
of competition on its local telephone business, but is intent on taking
advantage of the various opportunities that competition should provide. North
Pittsburgh is currently addressing potential competition by focusing on improved
customer satisfaction, reducing costs, increasing efficiency, restructuring
rates and examining new product offerings and new markets for entry.

          Long Distance and Access Services.  Telephone service by North
          ----------------------------------                            
Pittsburgh to locations outside of its franchised telephone service territory
but within the Local Access Transport Area (LATA) is furnished through switched
and special access connections with Bell Atlantic - Pennsylvania, Inc., (BAPA),
other independent telephone companies and, in some instances, IXCs, CAPs or
resellers.

     North Pittsburgh bills toll calls within the LATA to its customers using
toll rates contained in a Pennsylvania Telephone Association (PTA) tariff on
file with the PA PUC. North Pittsburgh retains the revenues for such calls and
pays network access charges to BAPA

                                       2
<PAGE>
 
and other telephone companies for terminating this toll traffic.  Conversely,
North Pittsburgh receives network access charge revenues for terminating the
traffic of others.

     North Pittsburgh is a participating Issuing Carrier in the National
Exchange Carrier Association (NECA) tariffs which are on file with the Federal
Communications Commission (FCC) in respect to the provision of network access to
IXCs and others for interstate telephone service to areas beyond the LATA. Such
tariffs contain the rates chargeable for interstate switched and special access
to and from North Pittsburgh's telephone facilities.  North Pittsburgh is also a
participating Issuing Carrier under the authority of a PTA tariff on file with
the PA PUC which contains the rates chargeable for intrastate switched and
special access from North Pittsburgh's telephone facilities to other
Pennsylvania locations and to North Pittsburgh's facilities from such locations.
Penn Telecom, as an IXC, markets intrastate and interstate toll services by
reselling bulk billed message toll services.  North Pittsburgh also provides
facilities for special circuits (alarms, data transmission, etc.).

     Access charges concerning interstate services are regulated by the FCC.  On
December 24, 1996, the FCC released a Notice of Proposed Rulemaking regarding
access charge reform. The proposed rules, in most significant aspects, are not
applicable to North Pittsburgh's wireline operation as they apply predominantly
to price cap regulated companies.  The FCC has indicated it will issue another
proposed rulemaking with respect to ROR companies which may affect North
Pittsburgh.  The PA PUC also has instituted access and universal service
investigations.

     Toll telecommunications services beyond North Pittsburgh's franchised
telephone service area and within the Pittsburgh LATA, hereinafter referred to
as intraLATA, are presently provided through interconnections with BAPA and
other telephone companies.  The PA PUC has ordered intraLATA Presubscription
(also known as equal access) under which a customer chooses his or her intraLATA
toll carrier similar to the choice currently made for an interLATA toll carrier.
North Pittsburgh implemented presubscription on August 8, 1997.  It is not
possible to determine the ultimate impact of intraLATA Presubscription, but it
is expected that it may result in some reduction of revenues.

     North Pittsburgh's unique location in a growing commercial/residential
suburban traffic corridor to the north of the City of Pittsburgh, its state-of-
the-art switching transmission and transport facilities and its extensive fiber
network place it in a solid position to meet competition and minimize any loss
of revenues.  In addition, North Pittsburgh continues to make its network
flexible and responsive to the needs of its customers to meet competitive
threats.  New services, access line growth and anticipated usage growth will
lessen or offset any reductions in North Pittsburgh's revenue sources.

          Directory Advertising, Billing and Other Services.  North Pittsburgh
          --------------------------------------------------                  
receives revenues from the sale of advertising space in telephone directories
and from billing and collection activities.  Directory Advertising is subject to
competition from a number of sources and, to date, efforts to meet such
competition have been successful.  Billing and collection services are provided
to various IXCs, including Penn Telecom.

          Telecommunication Equipment.  Penn Telecom sells, rents and services
          ----------------------------                                        
telecommunication equipment to customers generally in the Western Pennsylvania
area.  Penn

                                       3
<PAGE>
 
Telecom has been able to sustain its business activities in a strong,
competitive market. Penn Telecom is certified by the PA PUC to offer toll resale
services and has a tariff on file with the FCC to provide interstate toll
services and has recently petitioned the PA PUC for authority to operate as a
Competitive Local Exchange Carrier. As a reseller of both interstate and
intrastate toll services, Penn Telecom is in direct competition with other IXCs.

          Operating Revenues.  The respective amounts of operating revenues
          -------------------                                              
contributed by local network services, long distance and access services,
telecommunication equipment sales, directory advertising and billing and
collection services during each of the last three fiscal years are set forth in
the Financial Statements and Schedules provided in response to Item 8 and are
incorporated herein by reference.

          (ii) Other Services.

         (iii) Status of New Products.
               ---------------------- 

          This paragraph is not applicable.  The Registrant and its subsidiaries
have not made public any information concerning new products or services that
would require the investment of a material amount of the assets of the
Registrant or that otherwise would be material.

          (iv) Equipment Availability.
               ---------------------- 

          The Registrant and its subsidiaries have not  encountered, nor do they
anticipate, any difficulty in obtaining a ready  supply of telecommunication
equipment from manufacturer suppliers.  Although certain individual suppliers
may each supply more than 10 percent of their equipment requirements, the
Registrant and its subsidiaries are not primarily dependent upon any one
supplier with alternative suppliers of telecommunication equipment being readily
available.


          (v) Certificates, Franchises, Etc. and Licenses.
              ------------------------------------------- 

          North Pittsburgh holds valid, continuing and subsisting rights,
certificates, franchises, licenses (other than those mentioned in the following
paragraph) and renewable permits adequate for the conduct of its business in the
territory it serves, none of which contain any burdensome restrictions.
However, see Local Network Services under paragraph (c)(1)(i) concerning, inter
alia, impact of the 1996 Act.                                             -----
- ----

     North Pittsburgh has an FCC license to operate a private operational
telephone maintenance radio service station (WIK 838 expiring on March 20,
2001).  The FCC license to operate an Improved Mobile Telephone System (IMTS)
(call sign KGH-862) was discontinued as of January 1, 1998.  Renewal license
applications were filed on December 27, 1990 with the FCC for the continued
operation by North Pittsburgh of two point-to-point microwave systems (call
signs KG0-21 and KGN-88).  The FCC acknowledged such renewal applications in a
Public Notice dated March 21, 1991 indicating an expiration date of February 1,
2001.  A renewal license application was filed on February 4, 1998 with the FCC
for the continued operation by North Pittsburgh of a non-commercial private
license for its own maintenance radio service and other purposes (call sign WPCD
845 which will expire, after renewal, on April 29, 2003).  North Pittsburgh has
not encountered in the past, nor does it anticipate in the future, any
difficulty in renewing these FCC licenses.

          (vi) Seasonality of Business.
               ----------------------- 

               None of the business activities of the Registrant or its
subsidiaries are seasonal.

         (vii) Practices Relating to Working Capital.
               ------------------------------------- 

          This paragraph is not applicable.  No special practices relating to
working capital have been adopted by the Registrant or its subsidiaries.  (See
Item 7, Management's Discussion and Analysis of Financial Condition and Results
of Operations.)

        (viii) Customers.
               --------- 

          No material part of the overall business of the Registrant or it
subsidiaries is dependent upon a single customer or a few customers, the loss of
any one or more of whom would have a materially adverse effect on its business.

          (ix) Backlog of Orders.
               ----------------- 

          The Registrant and its subsidiaries do not have a significant backlog
of service and installation orders.  Improvements and expansion of their
facilities are, to the extent possible, made in anticipation of demands for
service and a reasonable and adequate inventory is maintained to meet the
requirements of customers.

          (x) Renegotiation of Profits or Termination of Contracts.
              ---------------------------------------------------- 

          The Registrant and its subsidiaries do not have a material portion of
their business subject to renegotiation of profits or termination of contracts
or subcontracts at the election of the Government.

          (xi) Competition.
               ------------

          The competitive environment faced by the Registrant in respect to the
services provided by it or by its subsidiaries is fully discussed under
paragraph (c)(1)(i) of this Item 1.

         (xii) Research Activities.
               ------------------- 

          The Registrant and its subsidiaries do not engage in any research
activities relating to the development of new products or services or the
improvement of existing products or services and no amounts have been expended
in the past three years for such activities.

        (xiii) Environmental Matters.
               --------------------- 

          Compliance with federal, state and local provisions which have been
adopted regulating the discharge of materials into the environment or otherwise
relating to the protection of the environment have not materially affected the
capital expenditures, earnings and competitive position of the Registrant and
its subsidiaries.

         (xiv) Employees.
               --------- 

          At December 31, 1997, the Registrant, through all of its subsidiaries,

Item 2.   Properties
- ------    ----------

     The Registrant owns in fee, an office/warehouse building which houses the
operations of Penn Telecom and leases excess space to unrelated businesses.

     The materially important physical properties of North Pittsburgh, all owned
in fee (except some rights-of-way) and most of which are held subject to certain
mortgage and security agreements executed in connection with loans through the
Rural Utilities Service, consist principally of land, buildings, central office
equipment, long distance switching facilities, transmission facilities, pole
lines, aerial cable, underground cable, aerial wire, buried cable, buried wire,
distribution wire, underground conduit, furniture, office and computer
equipment, garage facilities, vehicles and work equipment and generally any and
all property required to operate a modern telecommunications network.  Such
facilities are fully utilized except that improvement and expansion of those
facilities are, to the extent possible, made in anticipation of the demand for
service.  All of the foregoing properties are located within Allegheny,
Armstrong, Butler and Westmoreland Counties in Western Pennsylvania.

     From January 1, 1993 to December 31, 1997, North Pittsburgh made gross
property additions of approximately $66,611,000 (which is about 51.1% of the
original cost of the present telephone plant) and property retirements of
approximately $10,802,614.  North Pittsburgh's 1998 construction program,
subject to adjustment for economic conditions, postponements of housing
developments, etc. is projected to be in the $23 million to $26 million range
which includes central office equipment additions, distribution lines, etc. to
permit expansion or improvement of North Pittsburgh's telecommunications
services.

Item 3.   Legal Proceedings
- ------    -----------------

     As of the date hereof, except for regulatory matters before the PA PUC and
FCC, including matters which could result in the expansion of competition, there
were no material pending legal or governmental proceedings directly involving
the Registrant or its subsidiaries, other than ordinary routine litigation or
ordinary routine utility matters incidental to the business and matters as to
which the Registrant and its subsidiaries are insured.

Item 4.   Submission of Matters to a Vote of Security Holders

Item 7.  Management's Discussion and Analysis of Financial Condition
- -------  -----------------------------------------------------------
         and Results of Operations (Amounts in Thousands)
         ------------------------------------------------

                (a)  Results of Operations
                     ---------------------

     Net earnings for 1997 were $22,185, an increase of $10,455 (89.1%) over
1996 net earnings of $11,730.  The 1996 net earnings represented an increase of
$1,043 (9.8%) as compared to 1995.  These fluctuations were attributable to the
following factors:

                   (1)  Stock Sales
                        -----------

     As reported in its Current Report on Form 8-K, dated January 28, 1998, the
Registrant had an investment in the common stock of Conquest Telecommunications
Services Corporation (Conquest), a non-public company, engaged in the
development and marketing of prepaid calling cards and other enhanced
telecommunications services.  In 1997, SmarTalk Teleservices, Inc. (SmarTalk), a
public company, engaged, inter alia, in similar businesses, and Conquest
                         ----- ----                                     
announced the proposed acquisition of Conquest by SmarTalk. The merger was
completed on December 31, 1997. In connection with liquidating its investment in
Conquest, the Registrant entered into the following transactions which resulted
in a net pre-tax gain of $14,516 ($9,003 after income taxes, $.60 per share) in
1997.

          (i) In November 1997, the Registrant agreed to settle litigation
brought against it by certain other Conquest shareholders (Plaintiffs).  The
settlement agreement, which became effective only upon completion of the
proposed merger, resulted in a 1997 pre-tax loss of $3,180.  In January 1998,
the Registrant, in satisfaction of the settlement agreement, paid the Plaintiffs
$750 in cash and transferred 106,820 shares of SmarTalk stock (the Settlement
Shares) which it received upon completion of the merger.

          (ii) In order to ensure utilization of expiring tax loss
carryforwards, the Registrant entered into a transaction in December, 1997
whereby it sold a portion of its investment in Conquest to a third party for
cash resulting in a pre-tax gain of $1,572.  In addition, the Registrant granted
the buyer an option to purchase all of the SmarTalk shares it would receive upon
completion of the merger, except the Settlement Shares, at a price of $21 per
share (the Option Price).

          (iii) On December 31, 1997, the merger was completed and
the Registrant exchanged its remaining shares of Conquest common stock for
shares of SmarTalk common stock resulting in a realized pre-tax gain of $16,124.
As of December 31, 1997, the SmarTalk shares were included in Available for Sale
securities and were valued at the Option Price.  The option was exercised in
January, 1998 resulting in the Registrant selling its remaining SmarTalk shares
for cash.

                (2) Operating Revenues
                    ------------------

     Total operating revenues increased $6,274 (10.5%) during 1997.  This change
was principally due to increases in long distance and access services of $1,632
(3.9%), local network services of $1,525 (17.6%) and other operating revenues of
$2,958 (65.0%).  Higher long distance and access service revenues were generally
the result of an increase in the

                                       13
<PAGE>
 
number of customers and minutes of use.  However, the rate of increase has
slowed due to the introduction of an automatic savings plan in July, 1997.
Increased local network service revenues were attributable to customer growth,
growth in second lines, expanded penetration of enhanced services and line rate
increases for residential and business customers in several exchanges.  Other
operating revenues increased due to growth of Pinnatech's Internet access
customers and the growth of consulting and outsourcing services provided by MCSI
through July 31, 1997.

     Total operating revenues increased $7,176 (13.6%) during 1996.  This change
was principally due to increases in long distance and access services of $2,983
(7.7%), local network services of $1,160 (15.4%) and other operating revenues of
$2,582 (131.3%).  Higher long distance and access service revenues were
generally the result of an increase in the number of customers and in minutes of
use.  Increased local network service revenues were attributable to customer
growth, growth in second lines and expanded penetration of enhanced services.
Other operating revenues increased due to growth of Pinnatech's Internet access
customers, MCSI's consulting customers and the introduction of MCSI's data
processing outsourcing services.

                (3) Operating Expenses and Net Revenues
                    -----------------------------------

     Total operating expenses for 1997 increased $3,741 (9.3%) over the
preceding year. That change was principally the result of increases in network
and other operating expenses of $1,737 (6.7%) and depreciation and amortization
expenses of $1,169 (12.3%).  The increase in network and other operating expense
was principally due to an increase in Central Office switching expenses and an
increase in advertising costs.  The growth in depreciation and amortization
expenses is the direct result of the growth in fixed assets to serve current and
future customer needs.  The increase in total operating revenues of $6,274
discussed above, coupled with the increase in total operating expenses of
$3,741, resulted in a 12.9% increase in net operating revenues in 1997 as
compared to 1996.

     Total operating expenses for 1996 increased $6,601 (19.6%) over the
preceding year. That change was principally the result of increases in network
and other operating expenses of $4,931 (23.3%) and depreciation and amortization
expenses of $1,163 (14.0%). Approximately $4,000 of the $4,931 increase in
network and other operating expenses was directly associated with the increase
in other operating revenues of $2,582 discussed above. The growth in
depreciation and amortization expenses is the direct result of the growth in
fixed assets to serve current and future customer needs.  The increase in total
operating revenues of $7,176 discussed above coupled with the increase in total
operating expenses of $6,601 resulted in a modest 3% increase in net operating
revenues in 1996 as compared to 1995.

     The composition and amounts of sundry expense (income), net, is comparable
between 1996 and 1997.  Approximately $509 more of cellular partnership income
was recorded in 1996 than 1995.  Included in 1995 is approximately $567 of non-
recurring charges related to costs of start-up businesses.

          (b)   Liquidity and Capital Resources
                -------------------------------

     In 1987, North Pittsburgh exhausted the remaining unborrowed funds which
had first become available from the Rural Telephone Bank in 1977.  Information
relating to long-term debt is included in Note 2  to the Consolidated Financial
Statements. The Registrant and its subsidiaries financed capital expenditures,
debt service and dividend payments from internal sources from 1987 to 1996.

     In 1996, North Pittsburgh was granted approval for a loan from the Federal
Financing Bank (FFB) guaranteed by the  Rural Utilities Service in the maximum
principal amount of $75 million.  The maximum principal amount will be advanced
periodically over a five-year period which began on January 2, 1997 to furnish
or improve telephone service in rural areas. Funds were advanced in 1997 for
$3,132 and $3,771 with Interim Maturity Dates of June 30, 1998 and March 31,
1998, respectively. Per the Note Agreement with the FFB, North Pittsburgh
intends to elect to extend the maturity dates of the advances, but not beyond
the Final Maturity Date of December 31, 2012.

     North Pittsburgh established a line of credit in 1994 in the amount of $10
million with the Rural Telephone Finance Cooperative that is available for
general business purposes.  No borrowings have taken place against the line of
credit.

     Capital expenditure commitments for the purchase and installation of new
equipment at December 31, 1997 amounted to approximately $1.1 million, with such
amount being part of a 1998 construction program of $23 million to $26 million.
Management expects cash flows provided by operating activities and cash reserves
in 1998 to service long-term debt, to pay dividends and to finance approximately
25% to 50% of capital additions.  The balance of capital additions will be
financed from new borrowings.  It is anticipated that future payments for long-
term debt service will be made from the same sources of internally generated
funds.  Capital additions beyond 1998 are anticipated to be 25% internally
financed.

     Temporary excess funds are invested in short-term cash equivalents with
maturity dates scheduled to coincide with tax payment due dates, debt principal
payments, etc.  Management expects to continue the investment of such excess
funds in 1998 which will satisfactorily meet all short-term obligations.

            (c) Other Information
                -----------------

                (1)  Inflation and Changing Prices
                     -----------------------------
 
     During the three most recent fiscal years, inflation and changing prices
have not had a significant impact on net sales and on income from continuing
operations.

                (2)  Regulatory Assets
                     -----------------
 
     Management does not believe that the Registrant has any significant
regulatory assets or liabilities under Statement of Financial Accounting
Standards No. 71, "Accounting for the Effects of Certain Types of Regulation."
Historically, the Registrant has monitored closely the

                                       15
<PAGE>
 
economic lives of plant in service and has adjusted depreciable lives as
necessary to conform to generally accepted accounting principles.

                (3) Alternative Form of Regulation Petition
                    ---------------------------------------

     As discussed in Item 1(c)(i), North Pittsburgh, under Chapter 30 of the
Pennsylvania Public Utility Code, must, prior to July 8, 1998, file a petition
with the PA PUC for approval of an alternative form of regulation to replace
traditional rate base/rate of return regulation or be subject to a show cause
proceeding.  The petition must include a proposed network modernization plan.
Although North Pittsburgh has not determined the form and content of its
petition, the ultimate filing of such petition is expected to be of significance
to North Pittsburgh.  However, it is not possible at this time to determine the
PA PUC's disposition of any petition filed or the effect on North Pittsburgh's
financial position or results of operations.

                (4) Federal and State Regulatory Proceedings
                    ----------------------------------------

     The Federal Communications Commission (FCC) continues to work on
Rulemakings that will spell out the specifics of the Telecommunications Act of
1996 (the 1996 Act) and the PA PUC must then finalize its course of action to
fully implement the 1996 Act, or to the extent possible and permissible, change
the manner in which such regulations are implemented in Pennsylvania before the
impact on North Pittsburgh, a Rural Telephone Company under the 1996 Act, can be
fully understood and measured.  However, the clear intent of the 1996 Act is to
open up the local exchange market to competition.  This appears to mandate,
among other items, that North Pittsburgh, at some point in time, permit the
resale of its services at wholesale rates, provide number portability, if
feasible, provide dialing parity, provide interconnection to any requesting
carrier for the transmission and routing of telephone exchange service and
exchange access and provide access to network elements.  The Company joined with
17 other rural companies in Pennsylvania to file a Petition with the PA PUC
requesting a temporary suspension of the interconnection requirements of Section
251 of the 1996 Act for a two-year period following resolution of the FCC's
Universal Service and Access Reform Orders. The Petition was filed February 20,
1997 and the PA PUC approved the petition on July 10, 1997.

     The 1996 Act, FCC and PA PUC regulatory proceedings and the thrust towards
a fully competitive marketplace have created some uncertainty in respect to the
levels of North Pittsburgh's revenue growth in the future.  However, its unique
location in a growing commercial/residential suburban traffic corridor to the
north of the City of Pittsburgh, its state-of-the-art switching transmission and
transport facilities and its extensive fiber network place North Pittsburgh in a
solid position to meet competition and minimize any loss of revenues. In
addition, North Pittsburgh continues to make its network flexible and responsive
to the needs of its customers to meet competitive threats. New services, access
line growth and anticipated usage growth is expected to lessen or offset any
reductions in North Pittsburgh's revenue sources.

                (5)   Year 2000
                      ---------

     The Registrant has taken actions to understand the nature and extent of the
work required to make its systems and infrastructure Year 2000 compliant.  The
Registrant began

                                       16
<PAGE>
 
work last year to prepare its operational support, financial and other computer-
based systems for the Year 2000, including replacing and/or updating existing
legacy systems.  Some of the work is part of larger systems upgrades.  In mid-
1999, the Registrant will begin outsourcing operational support systems and
accounting functions currently performed in-house. The outsourcing vendors
report that their systems are Year 2000 compliant. These systems will enable the
Registrant to provide for its future data processing needs. The Registrant
estimates that the incremental costs associated with downsizing its internal
data processing workforce will be $1.5 million over the next two years. Other
costs associated with outsourcing data processing functions cannot be estimated
at this time. The Registrant expects to avoid disruption of its information,
telephony and business systems as a result of these efforts.

            (6) New Accounting Pronouncements
                -----------------------------

     Statements of Financial Accounting Standards No. 128, "Earnings Per Share",
No. 130, "Reporting Comprehensive Income Summary" and No. 131, "Disclosures
about Segments of an Enterprise and Related Information" were effective for the
year ended December 31, 1997. These statements have no material impact on the
Registrant.

The Board of Directors
North Pittsburgh Systems, Inc.:


We have audited the consolidated financial statements of North Pittsburgh
Systems, Inc. and subsidiaries (the Company) as listed in the accompanying
index.  In connection with our audits of the consolidated financial statements,
we also have audited the financial statement schedule as listed in the
accompanying index.  These consolidated financial statements and financial
statement schedule are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these consolidated financial
statements and financial statement schedule 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 consolidated financial statements referred to above present
fairly, in all material respects, the financial position of North Pittsburgh
Systems, Inc. and subsidiaries at December 31, 1997 and 1996, and the results of
their operations and their cash flows for each of the years in the three-year
period ended December 31, 1997, in conformity with generally accepted accounting
principles.  Also, in our opinion, the related financial statement schedule,
when considered in relation to the basic consolidated financial statements taken
as a whole, presents fairly, in all material respects, the information set forth
therein.

                   Notes to Consolidated Financial Statements

                        December 31, 1997, 1996 and 1995

                 (Amounts in Thousands, Except Per Share Data)


(1) Summary of Significant Accounting Policies
    ------------------------------------------

    Basis of Presentation and Consolidation
    ---------------------------------------

    The consolidated financial statements include the accounts of North
     Pittsburgh Systems, Inc. (the Company) and its subsidiaries, North
     Pittsburgh Telephone Company (NPTC), Penn Telecom, Inc. (PTI) and
     Pinnatech, Inc.  Also consolidated herein is the financial activity of
     Management Consulting Solutions, Inc. (MCSI) until its sale on July 31,
     1997.  The Company, through NPTC and PTI, is primarily engaged in providing
     telecommunications equipment and services to its customers generally
     located in western Pennsylvania.  All significant intercompany accounts and
     transactions have been eliminated in consolidation.

    The preparation of the consolidated financial statements in conformity with
     generally accepted accounting principles requires management to make
     estimates and assumptions that affect the reported amounts of assets,
     liabilities, revenues and expenses and disclosure of contingent assets and
     liabilities.  The estimates and assumptions used in the accompanying
     consolidated financial statements are based upon management's evaluation of
     the relevant facts and circumstances as of the date of the financial
     statements.  Actual results may differ from the estimates and assumptions
     used in preparing the accompanying consolidated financial statements.

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

    Revenues are recognized when earned.  Local service and intralata long
     distance revenues are subject to the jurisdiction of the Pennsylvania
     Public Utilities Commission (PUC).  The Company participates in interstate
     pooling arrangements with other telephone companies.  Such pools are funded
     by access service charges regulated by the Federal Communications
     Commission.  Revenue earned through pooling is initially recorded based on
     estimates.  The Company has settled substantially all access service
     arrangements through 1996.

                                                                   (Continued)

             Notes to Consolidated Financial Statements, Continued



   Marketable Securities
   ---------------------

   All marketable equity securities are considered available for sale, and debt
     securities are classified either as available for sale or held to maturity.
     Marketable securities available for sale are recorded at fair value, based
     on quoted market prices.  Significant changes in value of available for
     sale securities are included as a separate component of shareholders'
     equity.  Marketable securities held to maturity are recorded at amortized
     cost.  A decline in the fair value of any marketable investment security
     below cost, that is deemed other than temporary, is charged to earnings
     resulting in a new cost basis for the security.  Costs of investments sold
     are determined on the basis of specific identification.

   Investments
   -----------

   The Company's investments in three cellular limited partnerships are carried
     at cost plus equity in accumulated net profits or losses.  Other
     investments in nonmarketable securities are carried either at cost or at
     equity as the circumstances warrant.

   Property, Plant and Equipment
   -----------------------------

   Telephone plant in service is recorded at cost.  Retirements relating to
     replacements of telephone plant and equipment are accounted for in
     accordance with applicable regulations of the PUC.  Accordingly, the
     original costs of facilities retired, plus costs of removal, net of salvage
     or other credits, are charged to accumulated depreciation.

   Depreciation on telephone plant in service is provided on a straight-line
     basis over estimated useful lives of 10 to 30 years for buildings and 5 to
     20 years for equipment.  In 1995, the Company reduced estimated useful
     lives of cable and central office equipment due to technological and
     competitive changes in the telecommunications industry, resulting in a 1995
     charge of $593 ($357 after income taxes, $.02 per share).  Depreciation as
     a percentage of average depreciable plant in service amounted to 8.4%, 8.2%
     and 8.2% in 1997, 1996 and 1995, respectively.  The average remaining life
     of plant in service as of December 31, 1997, is approximately 6.0 years.

   On construction projects lasting 12 months or more, interest costs incurred
     on the related funds expended during the construction period are
     capitalized as part of the project cost in accordance with regulatory
     requirements.  No interest was capitalized during 1997, 1996 or 1995.

   Expenditures for maintenance, repairs and renewals are charged to operations
     as incurred.

                                                                     (Continued)

   Inventories
   -----------

   Inventories consist of telecommunication equipment and parts to provide
     service to, or to make sales to, the Company's customers.  Inventories are
     valued at the lower of cost (using the moving average method) or market.

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

   The Company provides telecommunication services to customers (business and
     residential) located in western Pennsylvania and access connectivity to
     interexchange carriers.  Access service settlements and other represent,
     for the most part, amounts due from interexchange carriers.

   The Company employs the direct write-off method for bad debts.  Uncollected
     accounts receivable are expensed approximately 90 days after telephone
     service to such customer has been disconnected.

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

   Income taxes are accounted for under the asset and liability method.
     Deferred tax assets and liabilities are recognized for the future tax
     consequences attributable to differences between the financial statement
     carrying amounts of existing assets and liabilities and their respective
     tax bases and operating loss and tax credit carryforwards.  Deferred tax
     assets and liabilities are measured using enacted tax rates expected to
     apply to taxable income in the years in which those temporary differences
     are expected to be recovered or settled.  The effect on deferred tax assets
     and liabilities of a change in tax rates is recognized in income in the
     period that includes the enactment date.

   Investment tax credits applicable to assets acquired or committed for by
     January 1, 1986, are being amortized over the average useful lives of the
     assets to which they relate.

   The Company and its subsidiaries file a consolidated federal income tax
     return.

   Cash Equivalents
   ----------------

   For purposes of the consolidated statements of cash flows, the Company
     considers all temporary investments with a maturity of three months or less
     to be cash equivalents.

    Postretirement Benefits
    -----------------------

    The Company provides pension and other postretirement benefits to
     substantially all of its employees and eligible retirees.  Benefits
     provided by these plans are expensed over the estimated working lives of
     employees.

    Earnings Per Share
    ------------------

    In 1997, the Company adopted the provisions of Statement of Financial
     Accounting Standards No. 128, "Earnings Per Share" (SFAS 128), which
     requires the presentation of "Basic Earnings Per Share" and "Diluted
     Earnings Per Share."  The adoption of SFAS 128 had no impact on the
     Company's calculation of earnings per share because the Company has no
     potential, dilutive common shares outstanding.

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

    Certain prior year amounts have been reclassified to conform with the
     current year's presentation.

(2) Long-Term Debt
    --------------

    Long-term debt as of December 31, 1997 and 1996, was as follows:

    Principal payments required over the next five years calculated on the
     outstanding indebtedness at December 31, 1997, are:  $803 in 1998; $857 in
     1999; $913 in 2000; $974 in 2001; and $1,039 in 2002.

                                                                     (Continued)

    The notes payable to the Rural Telephone Bank are secured by a supplemental
     Mortgage Agreement executed by NPTC which provides that substantially all
     of the property, plant and equipment of NPTC are subject to a lien or a
     security interest.  Such agreement contains restrictions regarding
     dividends and other distributions.  Under these restrictions, unless
     certain working capital and net worth levels are maintained, NPTC is not
     permitted to pay dividends on its capital stock (other than in shares of
     capital stock), or to make any other distributions to its shareholder, or
     purchase, redeem or retire any of its capital stock or make any investment
     in affiliated companies.  As of December 31, 1997, consolidated retained
     earnings of the Company of approximately $35,639 were available for
     dividends and other distributions.

    In 1996, NPTC was granted approval for a loan from the Federal Financing
     Bank (FFB) guaranteed by the Rural Utilities Service in the maximum
     principal amount of $75 million. The maximum principal amount will be
     advanced periodically over a five-year period beginning January 2, 1997, to
     furnish or improve telephone service in rural areas. In 1997, advances of
     $3,132 and $3,771 were made to the Company with interim maturity dates of
     June 30, 1998, and March 31, 1998, respectively. As permitted by the note
     agreement with the FFB, the Company intends to extend the maturity dates of
     the advances up to December 31, 2012.

    Based on borrowing rates currently available to the Company for loans with
     similar terms and maturities, the estimated fair value of long-term debt as
     of December 31, 1997, is $27,437.

    NPTC also has a $10 million line of credit at a rate of prime plus 1-1/2%
     with the Rural Telephone Finance Cooperative.  The line of credit was not
     used in 1997 or 1996.

(3) Retirement Plan
    ---------------

    Substantially all employees of the Company are covered by a noncontributory,
     defined benefit retirement plan.  The benefits are based on each employee's
     years of service and compensation.  The Company's funding policy is to
     contribute an amount annually that satisfies at least the minimum funding
     required under the Employee Retirement Income Security Act of 1974.  The
     assets of the plan are held in a trust and are invested in a variety of
     equity and fixed income securities.

                                                                   (Continued)

   For measurement purposes, the annual rate of increase in the per capita cost
     of covered benefits (i.e., healthcare cost trend rate) for 1997 was 10.3
     percent for participants whose coverage included Major Medical insurance
     and Point-of-Service Plan and 8.9 percent for participants who have Blue
     Cross/Blue Shield coverage only; the rates were assumed to decrease
     gradually to 5 percent by the year 2008 and remain at that level
     thereafter.  The healthcare cost trend rate assumption has a significant
     effect on the amounts reported.  For example, increasing the assumed
     healthcare cost trend rates by one percentage point in each year would
     increase the accumulated postretirement benefit obligation as of December
     31, 1997, by $462 and the aggregate of the service and interest cost
     components of net periodic postretirement benefit cost for the year ended
     December 31, 1997, by $59.

    The weighted-average discount rate used in determining the accumulated
     postretirement benefit obligation was 7 percent at December 31, 1997 and
     1996.  Salaries were assumed to increase at a rate of 5 percent per year in
     1997 and 6 percent per year in 1996 for current active employees for life
     insurance benefit projections.

   The valuation allowance for deferred tax assets relates to state loss
     carryforwards of subsidiaries and impairment write-downs.  The valuation
     allowance for deferred tax assets as of January 1, 1997 and 1996, was
     $1,287 and $1,188, respectively.  The net change in the total valuation
     allowance for the years ended December 31, 1997 and 1996, was a decrease of
     $845 and an increase of $99, respectively.  In assessing the realizability
     of deferred tax assets, management considers whether it is more likely than
     not that some portion or all of the deferred tax assets will not be
     realized.  The ultimate realization of deferred tax assets is dependent
     upon the generation of future taxable income during the periods in which
     those temporary differences become deductible.  Management considers the
     scheduled reversal of deferred tax liabilities, projected future taxable
     income and tax planning strategies in making this assessment.  Based upon
     the level of historical taxable income and projections for future taxable
     income over the periods which the deferred tax assets are deductible,
     management believes it is more likely than not the Company will realize the
     benefits of these deductible differences, net of the existing valuation
     allowances at December 31, 1997.  The amount of the deferred tax asset
     considered realizable, however, could be reduced in the near term if
     estimates of future taxable income during the carryforward period are
     reduced.

    In 1997 and 1996, the Company had capital calls amounting to $1,800 and
     $898, respectively, to maintain its ownership percentages in its cellular
     limited partnership investments.

   Since 1988, the Company has owned an investment in the common stock of
     Conquest Telecommunications Services Corporation (Conquest), a non-public
     company.  In 1997, SmarTalk Teleservices, Inc. (SmarTalk), a public
     company, announced a proposed acquisition of Conquest, which was completed
     on December 31, 1997.  In connection with liquidating its investment in
     Conquest, the Company entered into the following transactions which
     resulted in a net pre-tax gain of $14,516 ($9,003 after income taxes, $.60
     per share) in 1997.

     (1) In November 1997, the Company agreed to settle litigation brought
         against it by other Conquest shareholders (Plaintiffs).  The settlement
         agreement, which became effective only upon completion of the proposed
         acquisition, resulted in a 1997 pre-tax loss of $3,180.  In January
         1998, the Company  paid the Plaintiffs $750 in cash and $2,430 in

     (2) In order to utilize expiring tax loss carryforwards, the Company
         entered into a transaction in December 1997 whereby it sold a portion
         of its investment in Conquest to a third party for cash resulting in a
         pre-tax gain of $1,572.  In addition, the Company granted the buyer an
         option to purchase all of its SmarTalk shares, except the Settlement
         Shares, received upon completion of the acquisition, at $21 per share
         (the Option Price).

     (3) On December 31, 1997, the acquisition was completed, and the Company
         exchanged its remaining shares of Conquest common stock for shares of
         SmarTalk common stock resulting in a realized pre-tax gain of $16,124.
         As of December 31, 1997, the SmarTalk shares were included in
         available-for-sale securities (note 7) and were valued at the Option
         Price.  The option was exercised in January 1998 resulting in the
         Company exchanging its remaining SmarTalk shares for cash.
