</TABLE>

Net income decreased 3% or $1.6 during the three months ended June 30, 1998,
compared to the same period in 1997. Year-to-date net income includes an
extraordinary after-tax charge of $3.4 related to the early retirement of debt.
Excluding this charge, net income decreased 18% or $17.6 for the first six
months of 1998, compared to the same period in 1997. The three and six month
decline is primarily due to lower toll revenues and higher operating expenses,
partially offset by increased local service and other revenues.

</TABLE>

Total revenues and sales increased 1% or $2.1 during the second quarter of 1998
and 1% or $7.7 for the six months ended June 30, 1998, compared to the same
periods in 1997.

Local service revenues increased 4% or $6.2 and 4% or $13.1 for the three and
six months ended June 30, 1998, respectively, compared to the same periods in
1997. For the three months ended June 30, 1998, access line growth of 5%
generated increased revenues of $7.9 primarily from CentraNet(R). Year-to-date
access line growth of 5% generated increased revenues of $4 from basic local
services, $7.9 from CentraNet(R) and $1.9 from Integrated Services Digital
Network (ISDN) and Digital Channel Services (DCS). Partially offsetting the
year-to-date increases was a $3 decline in directory assistance and operator
services.

Network access service revenues decreased 5% or $6.8 and 3% or $6.5 for the
three and six months ended June 30, 1998, respectively, compared to the same
periods in 1997. The impact of interstate access rate reductions from the 1997
Federal Communications Commission (FCC) price cap resulted in a decrease in
network access service revenues of $12.2 in the second quarter and $24.4

year-to-date compared to the same periods in 1997. Also, the FCC ordered
significant changes that altered the structure of access charges collected by
the Company. These changes, effective January 1, 1998, resulted in a $12.9
decrease in network access revenues during the second quarter of 1998 and a $17
decrease year-to-date. Offsetting these decreases was an increase in minutes of
use of 9% in the second quarter and 10% year-to-date, which resulted in higher
revenues of $9.8 and $20.8, respectively. Also, special access revenues grew
$8.5 and $14.1 for the three and six month periods, respectively, due to greater
demand for increased bandwidth by Internet Service Providers (ISPs) and other
high-capacity users.

Toll service revenues decreased 28% and 29% for the three and six months ended
June 30, 1998, compared to the same periods in 1997. These decreases, totaling
$4.5 and $9.7, respectively, are primarily due to lower toll volumes resulting
from intraLATA (local access transport area) toll competition, including 10XXX
and 1+ presubscription.

Other services and sales revenues increased 9% or $7.2 and 8% or $10.8 for the
three and six months ended June 30, 1998, respectively, compared to the same
periods in 1997. These increases are largely the result of an increase in
billing and collection service revenues of $2.2 in the second quarter and $4
year-to-date, and a $1.4 increase for both periods in revenues from voice
messaging services. The results also reflect an increase of $2.1 and $4 relating
to the FCC's order increasing payphone compensation from interexchange carriers
for the three and six months ended June 30, 1998, respectively.

</TABLE>

Total operating costs and expenses increased 2% or $5.6 in the second quarter of
1998 and 6% or $37.1 year-to-date, compared to the same periods in 1997. The
increases are primarily due to an increase in access charges incurred to
terminate intraLATA toll calls outside the Company's territory of $7.9 and $11.6
for the three and six month periods ended June 30, 1998, respectively.
Additional factors included a $2.8 and $15.3 rise in maintenance and repair
costs associated with storm damage within the Company's service territories and
a $6 and $11 increase in information page billings from directory publications
for the three and six month periods, respectively. Offsetting

these increases was a decline in depreciation expense of $11.3 and $4.1 for the
three and six month periods, as a result of rate changes made in the second
quarter of 1997.

</TABLE>

Interest - net increased 14% or $2.1 in the second quarter of 1998 and 12% or
$3.7 year-to-date, compared to the same periods in 1997. The increase is
primarily due to an increase in interest expense due to higher average
short-term debt levels.

Income taxes decreased 9% or $3.4 in the second quarter of 1998 and 23% or $14.7
year-to-date, compared to the same periods in 1997. These decreases are
primarily due to corresponding decreases in pre-tax income and other tax
adjustments.

During the first quarter of 1998, the Company recorded an after-tax
extraordinary charge of $3.4, reflecting premiums paid on the redemption of
high-coupon debt prior to stated maturity.


CAPITAL RESOURCES AND LIQUIDITY

Management believes that the Company has adequate internal and external
resources available to meet ongoing operating requirements for construction of
new plant, modernization of facilities and payment of dividends. The Company
generally funds its construction program from operations, although external
financing is available. Short-term financings can be obtained through borrowings
from the Company's parent, GTE, or GTE Funding Incorporated (GTE Funding), a
wholly-owned subsidiary of the Company. GTE Funding provides short-term
financing and investment vehicles and cash management services for the Company
and six other of GTE's domestic telephone operating subsidiaries, each of which
is contractually obligated to repay all amounts borrowed by it from GTE Funding.
The Company participates with other affiliates in a $1,500, 364-day line of
credit. The Company has an existing shelf registration statement for an
additional $100 of debentures.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (CONTINUED)


The Company's primary source of funds during the first six months of 1998 was
cash from operations of $558.2 compared to $404.5 for the same period in 1997.
The year-to-year increase in cash from operations primarily reflects a decrease
in the Company's working capital requirements, partially offset by a slight
decline in results from operations.

The Company's capital expenditures during the first six months of 1998 were
$217.4 compared to $166.8 for the same period in 1997. The 1998 expenditures
reflect the Company's continued access line growth and modernization of current
facilities to support new products and expanded services. Although the capital
expenditures during the first six months of 1998 were higher than the same
period in 1997, the overall anticipated capital expenditures for 1998 are
expected to be comparable to capital expenditures during 1997.

Cash used in financing activities was $328.9 during the first six months of 1998
compared to $216.2 for the same period in 1997. This included dividend payments
of $93.7 in the first half of 1998 compared to $138.5 for the same period in
1997. Short-term financings, including the net change in affiliate notes,
decreased $395 for the first six months of 1998, compared to an increase of
$27.4 for the same period in 1997. In 1998, the Company paid $3.4 in premiums on
the retirement of $125 of long-term debt redeemed prior to stated maturity,
compared to $1.2 in premiums on the retirement of $103.9 of long-term debt and
preferred stock redeemed prior to stated maturity in 1997. The Company issued
$300 of 6.86% Series E debentures in February 1998. The Company recognized an
interest rate hedge loss of approximately $8.8 on the settlement of forward
contracts related to that debt issuance. The loss is being amortized over the
life of the associated refinanced debt.

In its April 2, 1998 filing on Form 8-K, GTE stated that because the MCI
shareholders had accepted a competing offer, GTE's offer for MCI was no longer
outstanding. As a result, the Company and GTE were removed from "Credit Watch"
by all rating agencies. The Company believes that its present investment grade
credit rating provides ready access to the capital markets at reasonable rates
and provides the Company with the financial flexibility necessary to pursue
growth opportunities as they arise.

OTHER MATTERS

Federal Regulatory Developments

The Company filed interstate access revisions during 1997 that became effective
June 3, 1997 and July 1, 1997. Overall, these filings resulted in a net annual
price reduction of $49. In 1997, the FCC issued an order to file revised access
rates effective January 1, 1998, which resulted in additional interstate access
charge reductions of approximately $4.9 annually.

In 1997, the FCC also ordered significant changes that altered the structure of
access charges collected by the Company, effective January 1, 1998. Generally,
the FCC reduced and restructured the per minute charges paid by long distance
carriers and implemented new per line charges. The FCC also created an access
charge structure that resulted in different access charges for residential
primary and secondary lines and single line and multi-line business access
lines. In aggregate, the annual reductions in usage sensitive access charges of
$17.3 paid by long distance carriers were offset by $17.9 of new per line
charges and the charges paid by end-users. Effective July 1, 1998, access
charges were further reduced by $12.3 annually in compliance with FCC
requirements to restate the impacts of access charge reform.

In May 1997, the FCC released a major decision relating to implementation of the
Telecommunications Act's provision on universal service. GTE and numerous other
parties have challenged the FCC's decision before the U.S. Court of Appeals for
the Fifth Circuit on the grounds that the FCC did not follow the requirements of
the Telecommunications Act to develop a sufficient, explicit and competitively
neutral universal service program. Oral argument is not expected until
mid-September 1998 at the earliest, with a final decision to be issued by
mid-1999.

On March 9, 1998, the FCC adopted a Memorandum Opinion and Order (MO&O)
clarifying the payphone-specific coding digit requirements set forth in the
previous payphone orders and granting limited waivers of the requirement that
local exchange carriers (LECs) provide payphone-specific coding digits to
payphone service providers (PSPs), and that PSPs provide payphone-specific
coding digits from their payphones to interexchange carriers (IXCs), before PSPs
can receive per-call compensation from IXCs for subscriber 800 and access code
calls. GTE was granted waivers through 1998 in this order for Flex-ANI (Flexible
Automatic Number Identification) implementation due to technical problems
associated with switch conversions. 

On April 3, 1998, the FCC issued another MO&O which granted the IXCs a waiver of
the per-call compensation requirement so that they may pay per-phone instead of
per-call compensation for the payphones for which the FCC had granted technology
waivers. GTE will receive per-phone compensation under this waiver until the
Flex-ANI capable offices are activated. Qualifying payphone calls from Flex-ANI
capable switches will then be eligible for per-call compensation rather than
per-phone.

In a related court case between MCI and the FCC, the U.S. Court of Appeals,
District of Columbia Circuit, upheld the fundamental premise underlying the
FCC's

approach to setting the per-call compensation rate for uncompensated payphone
calls, thereby supporting the ordered per-call compensation rate noted in the
March 9th order. At the same time, however, the Court held that the FCC had
failed to clearly explain its methodology on the development of that same
per-call compensation rate. The Court remanded this portion back to the FCC.

State Regulatory Developments

Florida Statutes, enacted in 1995 and revised in 1998, have replaced earnings
regulation with price regulation and opened the local-exchange to competition.
The Company became subject to price regulation effective January 3, 1996. Under
the price regulation provisions, basic service, multi-line business
local-exchange service and intrastate access rates are capped until January 1,
2000 and will continue to be capped for an additional two years unless the
Florida Public Service Commission determines that the level of competition
justifies the elimination of the cap. Subsequent to the price cap period, prices
for basic services can be increased by an inflation factor less 1% annually.
Rates for non-basic services, defined as services other than basic,
interconnection and network access, can increase by up to 6% per year if no
competition exists and up to 20% if there is more than one certified provider of
the service. Also, a change to the statutes eliminates a provision that had
required the Company to reduce intrastate access rates by at least 5% annually
until parity with 1994 interstate rates is attained. It has been replaced by a
provision that requires a reduction to intrastate access rates of 5% on July 1,
1998 and an additional 10% on October 1, 1998 with no further reductions
required. The estimated 1998 impact is an $8.8 revenue reduction and the future
estimated annual impact is a $26.4 reduction.

Other Developments

The Company is managing a class action lawsuit involving disputes over amounts
billed for rental telephones. In July 1997, a tentative settlement was reached
with the plaintiff. An order was issued conditionally certifying the class,
preliminarily approving the settlement, preliminarily enjoining all other
actions affecting the class, approving the class notice and establishing a
fairness hearing for November 26, 1997. The class notice was included in
residential bills in August 1997. A similar class action was filed in June 1997
and enjoined by the preliminary injunction. Having been denied intervention in
the first class action, the plaintiff in the second lawsuit has filed objections
to the proposed settlement. On December 16, 1997, the Court issued a final order
approving the settlement, certifying the class, overruling the objections of the
second class action suit that had

been filed in June and dismissing the case with prejudice. The appeal of the
Court's order by the plaintiff in the second lawsuit was dismissed and the
settlement became effective on June 3, 1998. The Company is in the process of
implementing the settlement.

In July 1997, Time Warner Communications (Time Warner) sued the Company and GTE
Media Ventures (GTEMV), an affiliate of the Company, for damages allegedly
arising out of the Company's construction of a video dialtone network which was
subsequently transferred to GTEMV for construction of a competing cable network.
In the lawsuit, Time Warner alleges that both the Company and GTEMV moved Time
Warner's facilities without authorization during installation of their
respective networks. In doing so, Time Warner alleges that the Company and GTEMV
violated the National Electric Safety Code, breached various pole attachment
agreements and damaged Time Warner's facilities. Time Warner's motion for a
temporary injunction was denied. The parties are presently engaged in settlement
discussions.


RECENT DEVELOPMENTS

On July 27, 1998, GTE and Bell Atlantic entered into a merger agreement
providing for the combination of the two companies in a merger of equals
transaction. Under terms of the definitive agreement, which was unanimously
approved by the board of directors of both companies, GTE shareholders will
receive 1.22 shares of Bell Atlantic stock for each GTE share they own. The
merger is expected to be accounted for as a pooling of interests, is subject to
shareholder and regulatory approval, and is expected to be completed during the
second half of 1999. For additional information regarding the merger, refer to
the Form 8-K filed by GTE dated July 27, 1998.

In April 1998, GTE announced a series of actions designed to further sharpen its
strategic focus and improve its competitive position by repositioning
non-strategic properties and reducing costs. GTE expects to generate after-tax
proceeds of $2,000 to $3,000 by selling non-strategic or under-performing
operations and plans to reduce annual costs by more than $500 through improved
efficiencies and productivity while it continues to invest in new high-growth
opportunities. The impact of this announcement on the Company is unknown at this
time. GTE's management is currently assessing its options and, as decisions are
finalized regarding the sale of non-strategic operations and cost reductions,
the Company could be affected.

GTE Florida Incorporated and Subsidiaries
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


(1)      BASIS OF PRESENTATION:

         The unaudited condensed consolidated financial statements included
         herein have been prepared by the Company pursuant to the rules and
         regulations of the Securities and Exchange Commission. Certain
         information and footnote disclosures normally included in financial
         statements prepared in accordance with generally accepted accounting
         principles have been condensed or omitted pursuant to such rules and
         regulations. However, in the opinion of management of the Company, the
         condensed consolidated financial statements include all adjustments,
         which consist only of normal recurring accruals, necessary to present
         fairly the financial information for such periods. These condensed
         consolidated financial statements should be read in conjunction with
         the consolidated financial statements and the notes thereto included in
         the Company's 1997 Annual Report on Form 10-K.

         Reclassifications of prior year data have been made, where appropriate,
         to conform to the 1998 presentation.

(2)      EXTRAORDINARY CHARGE:

         During the first quarter of 1998, the Company recorded an after-tax
         extraordinary charge of $3.4 million, reflecting premiums paid on the
         redemption of high-coupon debt prior to stated maturity.

(3)      DEBT:

         In February 1998, the Company issued $300 million of 6.86% Series E
         Debentures, due 2028. The net proceeds were used to finance the
         Company's construction program and for general corporate purposes. The
         Company recognized an interest rate hedge loss of approximately $8.8
         million on the settlement of forward contracts related to that debt 
         issuance. The loss is being amortized over the life of the associated
         refinanced debt.

(4)      RECENT ACCOUNTING PRONOUNCEMENTS:

         Computer Software

         In March 1998, the American Institute of Certified Public Accountants
         issued Statement of Position 98-1, "Accounting for the Costs of
         Computer Software Developed or Obtained for Internal Use" (SOP 98-1).
         SOP 98-1 defines internal-use software and establishes accounting
         standards for the costs of such software. The Company is currently
         assessing the impact of adopting SOP 98-1, and intends to implement as
         of January 1, 1999.

         Derivative Instruments and Hedging Activities

         In June 1998, the Financial Accounting Standards Board issued Statement
         of Financial Accounting Standards No. 133, "Accounting for Derivative
         Instruments and Hedging Activities" (FAS 133). FAS 133 establishes
         accounting and reporting standards for derivative instruments,
         including certain derivative instruments embedded in other contracts,
         and for hedging activities. The Company has not yet assessed the impact
         of adopting FAS 133.
