                         NOTES TO FINANCIAL STATEMENTS
                                  (Unaudited)
                                        
1.   Basis of Presentation

     Bell Atlantic - Delaware, Inc. (the Company) is a wholly owned subsidiary
of Bell Atlantic Corporation (Bell Atlantic). The accompanying unaudited
condensed financial statements have been prepared based upon Securities and
Exchange Commission rules that permit reduced disclosure for interim periods.
These financial statements include certain reclassifications in presentation and
certain retroactive adjustments to conform accounting methodologies as a result
of the merger of Bell Atlantic and NYNEX Corporation (NYNEX) (see Note 2). These
financial statements reflect all adjustments which are necessary for a fair
presentation of results of operations and financial position for the interim
periods shown including normal recurring accruals and other items (see Note 2).
The results for the interim periods are not necessarily indicative of results
for the full year. For a more complete discussion of significant accounting
policies and certain other information, refer to the financial statements filed
with the Company's 1996 Form 10-K.

2.   Bell Atlantic - NYNEX Merger

     On August 14, 1997, Bell Atlantic and NYNEX completed a merger of equals
under a definitive merger agreement entered into on April 21, 1996 and amended
on July 2, 1996.  The stockholders of each company approved the merger at
special meetings held in November 1996.  Under the terms of the amended
agreement, NYNEX became a wholly owned subsidiary of Bell Atlantic.  The merger
has been accounted for as a pooling of interests.

     As a result of conforming the accounting methodologies of Bell Atlantic and
NYNEX, the Company has recorded an after-tax charge of $418,000 to reinvested
earnings to recognize its liability for carryover vacation pay as if the merger
had occurred as of the beginning of the earliest period presented.

Merger-Related Costs

     Results of operations for the third quarter of 1997 include merger-related
pre-tax costs totaling approximately $1,700,000, consisting of $500,000 for
direct incremental costs and $1,200,000 for employee severance costs. A small
portion of costs for transition and integration were also incurred by the
Company. These costs include the Company's allocated share of merger-related
costs from Bell Atlantic Network Services, Inc. (NSI), an affiliate which
provides centralized services on a contract basis.

     Direct incremental costs consist of expenses associated with compensation
arrangements related to completing the merger transaction. Employee severance
costs represent the Company's proportionate share of benefit costs for the
separation by the end of 1999 of management employees who are entitled to
benefits under preexisting Bell Atlantic separation pay plans. Transition and
integration costs consist of the Company's proportionate share of costs
associated with integrating the operations of Bell Atlantic and NYNEX.

Additional Charges

     In the third quarter of 1997, the Company recorded pre-tax charges of
approximately $3,700,000 in connection with consolidating operations and
combining organizations and for special items arising in the quarter. These
charges include the Company's allocated share of charges from NSI. A discussion
of these charges follows:

     The Company recognized pre-tax charges of approximately $1,300,000 for the
write-down of obsolete fixed assets.

     The Company also recognized pre-tax charges of approximately $2,400,000 for
contingencies associated with various regulatory and legal matters.


3.   Dividend

     On November 3, 1997, the Company declared and paid a dividend in the amount
of $5,400,000 to Bell Atlantic.

                        Bell Atlantic - Delaware, Inc.

4.   Transfer of Directory Publishing Activities

     On January 1, 1997, the Company transferred, at net book value without gain
or loss, certain assets and liabilities associated with its directory publishing
activities to a newly formed, wholly owned subsidiary. The stock of the
subsidiary was immediately distributed to Bell Atlantic. The transfer of such
assets and liabilities was completed as part of Bell Atlantic's and the
Company's response to the requirements of the Telecommunications Act of 1996,
which prohibits the Company from engaging in electronic publishing or joint
sales and marketing of electronic products.

     Net assets transferred by the Company totaled approximately $3,500,000, and
consisted of deferred directory production costs (included in prepaid expenses),
fixed assets, and related deferred tax liabilities.

     Revenues and direct expenses related to the Company's directory publishing
activities transferred were approximately $33,800,000 and $11,400,000,
respectively, for the nine month period ended September 30, 1996. The Company
does not separately identify indirect expenses attributable to the directory
publishing activities, including expenses related to billing and data management
and processing services, legal, external affairs, depreciation, interest expense
and any corresponding tax expense.

5.   Litigation and Other Contingencies

     Various legal actions and regulatory proceedings are pending to which the
Company is a party. The Company has established reserves for liabilities in
connection with regulatory and legal matters which it currently deems to be
probable and estimable. The Company does not expect that the ultimate resolution
of these matters in future periods will have a material effect on the Company's
financial position, but it could have a material effect on results of
operations.

Item 2.  Management's Discussion and Analysis of Results of Operations
         (Abbreviated pursuant to General Instruction H(2).)

     This discussion should be read in conjunction with the Financial Statements
and Notes to Financial Statements.

RESULTS OF OPERATIONS
---------------------

     The Company reported net income for the first nine months of 1997 of
$26,462,000, compared to net income of $31,343,000 for the same period in 1996.

Bell Atlantic - NYNEX Merger

     On August 14, 1997, Bell Atlantic and NYNEX completed a merger of equals
under a definitive merger agreement entered into on April 21, 1996 and amended
on July 2, 1996. The stockholders of each company approved the merger at special
meetings held in November 1996. Under the terms of the amended agreement, NYNEX
became a wholly owned subsidiary of Bell Atlantic. The merger has been accounted
for as a pooling of interests.

     As a result of conforming the accounting methodologies of Bell Atlantic and
NYNEX, the Company has recorded an after-tax charge of $418,000 to reinvested
earnings to recognize its liability for carryover vacation pay as if the merger
had occurred as of the beginning of the earliest period presented.

Merger-Related Costs

     Results of operations for the third quarter of 1997 include merger-related
pre-tax costs totaling approximately $1,700,000, consisting of $500,000 for
direct incremental costs and $1,200,000 for employee severance costs. A small
portion of costs for transition and integration were also incurred by the
Company. These costs include the Company's allocated share of merger-related
costs from Bell Atlantic Network Services, Inc. (NSI), an affiliate which
provides centralized services on a contract basis.

     Direct incremental costs consist of expenses associated with compensation
arrangements related to completing the merger transaction. Employee severance
costs represent the Company's proportionate share of benefit costs for the
separation by the end of 1999 of management employees who are entitled to
benefits under preexisting Bell Atlantic separation pay plans. Transition and
integration costs consist of the Company's proportionate share of costs
associated with integrating the operations of Bell Atlantic and NYNEX.

     Bell Atlantic expects to incur between $400 million and $500 million (pre-
tax) in additional transition and integration merger-related expenses over the
three years following the closing of the merger. It is anticipated that the
Company will recognize a portion of these costs.

Additional Charges

     In the third quarter of 1997, the Company recorded pre-tax charges of
approximately $3,700,000 in connection with consolidating operations and
combining organizations and for special items arising in the quarter. These
charges include the Company's allocated share of charges from NSI. A discussion
of these charges follows:

     The Company recognized pre-tax charges of approximately $1,300,000 for the

     The Company also recognized pre-tax charges of approximately $2,400,000 for

     Net assets transferred by the Company totaled approximately $3,500,000, and
consisted of deferred directory production costs (included in prepaid expenses),
fixed assets, and related deferred tax liabilities.

     Revenues and direct expenses related to the Company's directory publishing
activities transferred were approximately $33,800,000 and $11,400,000,
respectively, for the nine month period ended September 30, 1996. The Company
does not separately identify indirect expenses attributable to the directory
publishing activities, including expenses related to billing and data management
and processing services, legal, external affairs, depreciation, interest expense
and any corresponding tax expense.

     Effective January 1, 1997, revenues from directory publishing activities
transferred are no longer earned, and the related expenses are no longer
incurred, by the Company. Certain other revenues, primarily fees for non-
publication of telephone numbers and multiple white page listings continue to be
earned by the Company. Additionally, contracts between the Company and another
affiliate of Bell Atlantic for billing and collection services related to the
directory activities, use of directory listings, and rental charges have created
new revenue sources for the Company.

Cumulative Effect of Change in Accounting - Directory Publishing

     The Company changed its method of accounting for directory publishing
revenues and expenses, effective January 1, 1996. The Company adopted the point-
of-publication method, which requires directory revenues and expenses to be
recognized upon publication rather than over the lives of the directories. The
Company recorded an after-tax increase in income of $88,000 in the first quarter
of 1996, representing the cumulative effect of this accounting change. Results
of operations for the first three quarters of 1996 were restated to reflect the
impact of this change.

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

     These and other items affecting the comparison of the Company's results of
operations for the nine month periods ended September 30, 1997 and 1996 are
discussed in the following sections. This Management's Discussion and Analysis
should also be read in conjunction with the Company's 1996 Annual Report on Form
10-K.

LOCAL SERVICE REVENUES

     1997-1996                      Increase
--------------------------------------------------------------------------------
     Nine Months          $10,948             11.2%
--------------------------------------------------------------------------------

     Local service revenues are earned by the Company from the provision of
local exchange, local private line, public telephone (pay phone) and value-added
services. Value-added services are a family of services which expand the
utilization of the network. These services include products such as Caller ID,
Call Waiting and Return Call, as well as more mature products such as Touch-
Tone.

     Higher usage of the Company's network facilities was the primary reason for
the increase in local service revenues in the nine months ended September 30,
1997. This growth was generated by an increase in access lines in service of
4.3% from September 30, 1996. This access line growth primarily reflects higher
demand for Centrex services and an increase in additional residential lines.
Higher revenues from private line and switched data services also contributed to
the revenue growth in 1997.

     Revenue growth in 1997 was boosted by increased revenues from value-added
services. This increase was principally the result of higher customer demand and
usage, fueled in part by the introduction of new and enhanced optional features.

     For a discussion of the Telecommunications Act of 1996, which will open the
local exchange market to competition, see "Factors That May Impact Future

     1997-1996                      Increase
--------------------------------------------------------------------------------
     Nine Months             $358               .7%
--------------------------------------------------------------------------------

     Network access revenues are earned from long distance carriers for their
use of the Company's local exchange facilities in providing long distance
services to their customers, and from end-user subscribers. Switched access
revenues are derived from usage-based charges paid by long distance carriers for
access to the Company's network. Special access revenues arise from access
charges paid by long distance carriers and end-users who have private networks.
End-user access revenues are earned from the Company's customers who pay for
access to the network.

     Network access revenues increased in the first nine months of 1997 due to
higher customer demand as reflected by growth in access minutes of use of 5.1%
in the nine month period of 1997 over the same period last year. Volume growth
was boosted by the expansion of the business market, particularly for high
capacity services. Higher end-user revenues attributable to an increase in
access lines in service also contributed to revenue growth in 1997.

     Volume-related growth was partially offset by the effect of price
reductions mandated by the Federal Communications Commission (FCC). Effective
July 1, 1997, the Company implemented price decreases of approximately
$6,600,000 on an annual

basis for interstate access services, in connection with the FCC's price cap
plan. Revenues also were reduced by special charges for contingencies associated
with regulatory matters, as previously discussed.

     It is expected that the impact of price decreases, in connection with the
FCC's price cap plan effective July 1, 1997, will be more than offset by volume
increases and the effect of prior year accruals. For a further discussion of FCC
rulemakings concerning price caps, access charges and universal service, see
"Factors That May Impact Future Results - Recent Developments - FCC Orders"

LONG DISTANCE SERVICES REVENUES

     1997-1996                     (Decrease)
--------------------------------------------------------------------------------
     Nine Months            $(525)            (2.2)%
--------------------------------------------------------------------------------

     Long distance services revenues are earned primarily from calls made
outside a customer's local calling area, but within the same service area of the
Company (intraLATA toll). Other long distance services include 800 services and
Wide Area Telephone Service (WATS).

     Increased competition for intraLATA toll, WATS and private line services
contributed substantially to the reduction in long distance services revenues in
1997. The effect on revenues and message volumes from competition for long
distance services increased in the third quarter of 1997 as a result of the
introduction of presubscription. These revenue decreases were partially offset
by growth in toll message volumes of 5.8% in the first nine months of 1997 as
compared to the same period in 1996.

     The Company believes that competition for long distance services, including
the introduction of presubscription in the third quarter of 1997, will continue
to impact future revenue trends. See "Factors That May Impact Future Results -
Competition - IntraLATA Toll Services" on page 15 for a further discussion of
presubscription.


ANCILLARY SERVICES REVENUES

     1997-1996                      Increase
--------------------------------------------------------------------------------
     Nine Months           $2,462             20.1%
--------------------------------------------------------------------------------

     The Company provides ancillary services which include billing and
collection services for long distance carriers and affiliates, customer premises
equipment (CPE) services, facilities rental services for affiliates and non-
affiliates, voice messaging, sales of materials and supplies to affiliates, ISDN
and other high bandwidth services.

     Higher ancillary services revenues in 1997 resulted from increases in
facilities rental revenues from affiliates and nonperformance fees received from
a vendor. Revenue growth from voice messaging services, principally Answer Call,
and billing and collection services performed for affiliates also contributed to
higher revenues in 1997.


DIRECTORY AND INFORMATION SERVICES REVENUES

     1997-1996                     (Decrease)
--------------------------------------------------------------------------------
     Nine Months         $(33,570)           (95.4)%
--------------------------------------------------------------------------------

     As described earlier, the Company transferred certain assets and
liabilities associated with its directory publishing activities to a newly
formed, wholly owned subsidiary, effective January 1, 1997. As a result,
revenues associated with directory publishing activities transferred are no
longer earned by the Company. The Company's directory and information services
revenues in 1997 are earned primarily from fees for non-publication of telephone
numbers, multiple white page listings and usage of directory listings.

     The decrease in directory and information services revenues in 1997 was
principally due to the effect of the transfer of directory publishing
activities.

EMPLOYEE COSTS

     1997-1996                     (Decrease)
--------------------------------------------------------------------------------
     Nine Months          $(5,132)           (11.9)%
--------------------------------------------------------------------------------

     Employee costs consist of salaries, wages and other employee compensation,
employee benefits and payroll taxes paid directly by the Company. Similar costs
incurred by employees of Bell Atlantic Network Services, Inc. (NSI), who provide
centralized services on a contract basis, are allocated to the Company and are
included in other operating expenses.

     The decrease in employee costs was primarily due to a reduction in benefit
costs caused by a number of factors, including an increase in the discount rate
used to develop pension and postretirement benefit costs, favorable pension plan
asset returns and lower than expected medical claims. Lower overtime pay and a
decline in the level of employee costs incurred for repair and maintenance
activity also contributed to the expense reduction in 1997. This decline was
partially due to the impact of the severe weather experienced in the first
quarter of 1996 which caused a higher level of costs to be expensed during that
period.

     These cost reductions were partially offset by annual salary and wage
increases, the effect of increased work force levels principally as a result of
higher business volumes, and merger-related costs recorded in the third quarter
of 1997. As described earlier, the Company recognized approximately $300,000 in
benefit costs for the separation by the end of 1999 of management employees who
are entitled to benefits under preexisting Bell Atlantic separation pay plans.
The Company also recorded approximately $200,000 for direct incremental merger-
related costs associated with compensation arrangements. Merger-related costs
associated with employees of NSI were allocated to the Company and are included
in other operating expenses.


DEPRECIATION AND AMORTIZATION

     1997-1996                      Increase
--------------------------------------------------------------------------------
     Nine Months           $3,752              8.9%
--------------------------------------------------------------------------------

     Depreciation and amortization increased in the first nine months of 1997 as
a result of the recording of approximately $1,300,000 for the write-down of
obsolete fixed assets in the third quarter of 1997, as previously mentioned.
Charges associated with the write-down of obsolete fixed assets of NSI were
allocated to the Company and are included in other operating expenses. Higher
depreciation expense was also caused by growth in depreciable telephone plant.
These expense increases were partially offset by the effect of lower rates of
depreciation and amortization.

TAXES OTHER THAN INCOME

     1997-1996                     (Decrease)
--------------------------------------------------------------------------------
     Nine Months             $(72)            (1.7)%
--------------------------------------------------------------------------------

     Taxes other than income consist of taxes for gross receipts, property,
capital stock and other nonincome-based items.

     The decrease in taxes other than income was primarily due to prior period
adjustments to the federal superfund tax recorded in 1997. This decrease was
partially offset by higher property tax expense.


OTHER OPERATING EXPENSES

     1997-1996                     (Decrease)
--------------------------------------------------------------------------------
     Nine Months          $(9,870)           (14.1)%
--------------------------------------------------------------------------------

     Other operating expenses consist of contract services including centralized
services expenses allocated from NSI, rent, network software costs, the
provision for uncollectible accounts receivable, and other costs.

     As a result of the transfer of directory publishing activities, certain
direct and allocated expenses related to the activities transferred are no
longer incurred by the Company.

     The decrease in other operating expenses was primarily attributable to the
effect of the transfer of directory publishing activities. This decrease was
partially offset by the Company's allocated share of employee severance costs,
direct incremental and transition merger-related costs and charges associated
with the write-down of obsolete fixed assets incurred by NSI.


OTHER INCOME AND (EXPENSE), NET

     1997-1996                      Increase
--------------------------------------------------------------------------------
     Nine Months             $393            172.4%
--------------------------------------------------------------------------------

     The change in other income and (expense), net, was primarily attributable
to the effect of a loss related to the disposition of certain property
recognized in the third quarter of 1996. Additional interest income primarily
resulting from the purchase of short-term investments in December 1996 to
prefund a trust for the payment of certain employee benefits also contributed to
the change in other income and (expense), net.


INTEREST EXPENSE

     1997-1996                      Increase
--------------------------------------------------------------------------------
     Nine Months             $942             15.9%
--------------------------------------------------------------------------------

     Interest expense increased principally due to a reduction in capitalized
interest costs resulting from lower levels of telephone plant under
construction.

EFFECTIVE INCOME TAX RATES

     Nine Months Ended September 30
--------------------------------------------------------------------------------
     1997                            39.6%
--------------------------------------------------------------------------------
     1996                            41.5%
--------------------------------------------------------------------------------

     The effective income tax rate is the provision for income taxes as a
percentage of income before provision for income taxes and cumulative effect of
change in accounting principle. The Company's effective income tax rate was
lower in the first nine months of 1997 principally due to the effect of prior
period adjustments recorded in 1996.


FINANCIAL CONDITION
-------------------

     The Company uses the net cash generated from operations and from external
financing to fund capital expenditures for network expansion and modernization,
and pay dividends. While current liabilities exceeded current assets at
September 30, 1997, September 30, 1996 and December 31, 1996, the Company's
sources of funds, primarily from operations and, to the extent necessary, from
readily available financing arrangements with an affiliate, are sufficient to
meet ongoing operating requirements. Management expects that presently
foreseeable capital requirements will continue to be financed primarily through
internally generated funds. Additional long-term debt may be needed to fund
development activities or to maintain the Company's capital structure to ensure
financial flexibility.

     As of September 30, 1997, the Company had $14,541,000 of an unused line of
credit with an affiliate, Bell Atlantic Network Funding Corporation.

     The Company's debt ratio was 50.7% as of September 30, 1997, compared to
48.6% as of September 30, 1996 and 48.7% as of December 31, 1996.

     On November 3, 1997, the Company declared and paid a dividend in the amount
of $5,400,000 to Bell Atlantic.


FACTORS THAT MAY IMPACT FUTURE RESULTS
--------------------------------------

Bell Atlantic- NYNEX Merger

     The merger of Bell Atlantic and NYNEX was completed on August 14, 1997. 
Bell Atlantic expects to recognize recurring expense savings following 
completion of the merger as a result of consolidating operating systems and 
other administrative functions and reducing management positions. It is 
anticipated that the Company will recognize a portion of these savings.

Telecommunications Industry Changes

     The telecommunications industry is undergoing substantial changes as a
result of the Telecommunications Act of 1996 (the Act), other public policy
changes and technological advances. These changes are likely to bring increased
competitive pressures in the Company's current business, but will also open new
markets to Bell Atlantic.

     The Act became law on February 8, 1996 and replaced the Modification of
Final Judgment (MFJ). In general, the Act includes provisions that open local
exchange markets to competition and permit Bell Atlantic to provide interLATA
(long distance) services and to engage in manufacturing, previously prohibited
by the MFJ. However, the ability of Bell Atlantic to provide in-region long
distance service is largely dependent on satisfying certain conditions contained
in the Act. The requirements include a 14-point "competitive checklist" of steps
the Company must take which will help competitors offer local service, through
resale, the purchase of unbundled network elements, or through their own
networks. Bell Atlantic must also demonstrate to the FCC that its entry into the
in-region long distance market would be in the public interest.

     Bell Atlantic expects to petition the FCC for permission to enter the in-
region long distance market in New York by early 1998 and one or more other
states during the first half of 1998, and anticipates entering the long distance
market in at least one jurisdiction during the second half of 1998. The timing
of Bell Atlantic's long distance entry in each of its 14 jurisdictions 

                                       13
<PAGE>
 
                        Bell Atlantic - Delaware, Inc.

depends on the receipt of FCC approval. There can be no assurance that any
approval will be forthcoming in time to permit Bell Atlantic to enter the in-
region long distance market on this schedule.

     A U.S. Court of Appeals recently found that the FCC unlawfully attempted to
preempt state authority in implementing key provisions of the Act. It also found
that several particularly objectionable provisions of the FCC's rules were
inconsistent with the statutory requirements. In particular, it affirmed that
states have exclusive jurisdiction over the pricing of interconnection elements
and that the FCC could not lawfully allow competitors to "pick and choose"
isolated terms out of negotiated interconnection agreements. This decision
should not delay the advent of local competition, since, under the previous stay
of the FCC's rules, a number of interconnection agreements have been concluded
and the Delaware Public Service Commission (PSC) has proceeded to address
pricing and other standards for local interconnection.

     On December 30, 1996, the PSC established a schedule for its consideration
of the Company's "Statement of Generally Available Terms and Conditions for
Interconnection, Unbundled Network Elements, Ancillary Services and Resale of
Telecommunications Services," to establish the template for telecommunications
competition in Delaware. The PSC issued its Findings and Opinions on this filing
on July 8, 1997. The Company filed a petition for reconsideration on July 18,
1997, which was denied by the PSC on July 29, 1997. The Company appealed the
PSC's decision to the federal district court in Delaware on September 8, 1997.
While the appeal is pending, competitors may continue to purchase network
elements at the prices established by the PSC.

     The Company is unable to predict definitively the impact that the Act will
ultimately have on its business, results of operations or financial condition.
The financial impact will depend on several factors, including the timing,
extent and success of competition in the Company's markets, and the timing,
extent and success of Bell Atlantic's pursuit of new opportunities resulting
from the Act.

     The Company anticipates that these industry changes, together with the
rapid growth, enormous size and global scope of these markets, will attract new
entrants and encourage existing competitors to broaden their offerings. Current
and potential competitors in telecommunication services include long distance
companies, other local telephone companies, cable companies, wireless service
providers, and other companies that offer network services. Some of these
companies have a strong market presence, brand recognition and existing customer
relationships, all of which contribute to intensifying competition and may
affect the Company's future revenue growth. See the "Competition" section below
for additional information.

Recent Developments - FCC Orders

     On May 7, 1997, the FCC adopted orders to reform the interstate access
charge system, to modify its price cap system and to implement the "universal
service" requirements of the Act. While there are additional decisions pending
on Universal Service and Access Reform, based on the decisions to date the
Company does not believe that these proceedings will result in a material
adverse impact on its results of operations or financial condition.

     Access Charges

     Interstate access charges are the rates long distance carriers pay for use
and availability of the Company's facilities for the origination and termination
of interstate interLATA service. On May 7, 1997, the FCC adopted changes to the
tariff structures it has prescribed for such charges in order to permit the
Company to recover a greater portion of its costs through rates which reflect
the manner in which those costs are incurred. Beginning in January 1998, the FCC
will require a phased restructuring of access charges, so that interstate costs
of the Company which do not vary based on usage will be recovered from long
distance carriers through flat rate charges, and those interstate costs that do
vary based on usage be recovered from long distance carriers through usage-based
rates. In addition, the FCC will require establishment of separate usage-based
charges for originating and for terminating interstate interLATA traffic.

     A portion of the Company's interstate costs are also recovered through flat
monthly charges to subscribers (subscriber line charges). Under the FCC's order,
subscriber line charges for primary residential and single line businesses will
remain unchanged initially, but such charges for additional residential lines
and multi-line businesses will rise.

<PAGE>
 
                        Bell Atlantic - Delaware, Inc.

     Price Caps

     The FCC also adopted modifications to its price cap rules that affect
access rate levels. Under the FCC's price cap rules, the Company's price cap
index is adjusted annually by an inflation index (GDP-PI) less a fixed
percentage intended to reflect increases in productivity (Productivity Factor).
In the prior year, the Company's Productivity Factor was 5.3%. Effective July 1,
1997, the FCC created a single Productivity Factor of 6.5% for all price cap
companies, and eliminated requirements to share a portion of future interstate
earnings. The FCC required that rates be set as if the higher Productivity
Factor had been in effect since July 1996. Any local exchange company that earns
a rate of return on its interstate services of less than 10.25% in any calendar
year will be permitted to increase its interstate rates in the following year.
The FCC also ordered elimination of recovery for amortized costs associated with
the Company's implementation of equal access to all long distance carriers.

     On June 30, 1997, Bell Atlantic made its Annual Access Tariff Filing of
Interstate Rates, which became effective on July 1, 1997. The rates included in
the filing resulted in annual price decreases for the Company totaling
approximately $6,600,000, of which $1,500,000 is a result of one-time
adjustments which will only be in effect until July 1998.

     The FCC is expected to adopt an order in 1998 to address the conditions
under which the FCC would relax or remove existing access rate structure
requirements and price cap restrictions as increased local market competition
develops. The Company is unable to predict the results of this further
proceeding.

     Universal Service

     The FCC also adopted rules designed to preserve "universal service" by
ensuring that a basket of designated services is widely available and affordable
to all customers, including low-income customers and customers in areas that are
expensive to serve. The FCC's universal service support will approximate $1.5
billion for high cost areas pending completion of further FCC proceedings. The
FCC, in conjunction with the Federal-State Joint Board on Universal Service,
will determine the methodology for determining high cost areas for non-rural
carriers, and the proper amount of federal universal service support for high
cost areas. A new federal high cost universal service support mechanism will
become effective January 1, 1999.

     The FCC also adopted rules to implement the Act's requirements to provide
discounted telecommunications services to schools and libraries, beginning
January 1, 1998, and to ensure that not-for-profit rural health care providers
have access to such services at rates comparable to those charged their urban
counterparts.

     All telecommunications carriers will be required to contribute funding for
these universal service programs. The federal universal service funding needs as
of January 1, 1998 will require the Company to contribute approximately 2% of
its interstate retail revenues for high cost and low income subsidies. The
Company will also be contributing a portion of its total retail revenues for
schools, libraries and not-for-profit health care. The Company will recover its
contributions through interstate charges to long distance carriers and end
users.

Competition

     IntraLATA Toll Services

     IntraLATA toll services are calls that originate and terminate within the
same LATA, but cover a greater distance than a local call. These services are
generally regulated by the PSC rather than federal authorities. The PSC permits
other carriers to offer intrastate intraLATA toll services in the Company's
jurisdiction.

     On September 15, 1997, the Company implemented presubscription as required
by the PSC. Presubscription enables customers to make intraLATA toll calls using
a competing carrier without having to dial an access code. Prior to the
implementation of presubscription, these toll calls were completed by the
Company unless the customer dialed a code to access another carrier.

     Implementation of presubscription for intraLATA toll services could have a
material negative effect on intraLATA toll services revenues, especially since
Bell Atlantic is not permitted to offer long distance services at this time. The
adverse impact on intraLATA toll services revenues is expected to be partially
offset by an increase in intraLATA access revenues.

     Local Exchange Services

     Local exchange services have historically been subject to regulation by the
PSC. Since July 1996, applications from competitors to provide and resell local
exchange services had been conditionally approved by the PSC, subject to the
outcome of a proceeding to consider interim rules for local exchange competition
or approval of an interconnection agreement. PSC interim rules were established
and applications which had been conditionally approved by the PSC were made
final as of April 11, 1997. The Act is expected to significantly increase the
level of competition in the Company's local exchange market.
