                    KNOLOGY HOLDINGS, INC. AND SUBSIDIARIES

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS



                                 JUNE 30, 1999
                                  (UNAUDITED)



1.       ORGANIZATION AND NATURE OF BUSINESS

         KNOLOGY (the "Company") offers residential and business customers
         broadband communications services ("Broadband Services"), including
         analog and digital cable television, local and long distance
         telephone, high-speed Internet access service, and broadband carrier
         services ("BCS"), using high capacity hybrid fiber-coaxial networks
         that are two-way interactive ("Interactive Broadband Networks") to
         provide these Broadband Services. The Company operates Interactive
         Broadband Networks in five metropolitan areas (collectively the
         "Systems"): Montgomery, Alabama; Columbus and Augusta, Georgia; Panama
         City, Florida; and Charleston, South Carolina and plans to expand to
         additional mid-sized cities in the southeastern United States. In
         addition, KNOLOGY provides analog cable television services in
         Huntsville, Alabama and is currently upgrading the Huntsville network
         to an Interactive Broadband Network, which will allow the Company to
         offer additional Broadband Services in the Huntsville market.

         The Company has experienced operating losses as a result of the
         expansion of the advanced broadband communications networks and
         services into new and existing markets. Management expects to continue
         the focus on increasing the customer base and expanding the broadband
         operations. Accordingly, operating expenses and capital expenditures
         will continue to increase with the extension of the broadband
         communications networks in existing and new markets in accordance with
         the business plan. While management expects its expansion plans to
         result in profitability, there can be no assurance that growth in the
         Company's revenue or customer base will continue or that the Company
         will be able to achieve or sustain profitability and/or positive cash
         flow.

2.       BASIS OF PRESENTATION

         The accompanying unaudited condensed consolidated financial statements
         of the Company have been prepared in accordance with generally
         accepted accounting principles for interim financial information and
         with the instructions to Form 10-Q and Article 10 of Regulation S-X.
         Accordingly, they do not include all of the information and footnotes
         required by generally accepted accounting principles for complete
         financial statements. In the opinion of management, all adjustments
         considered necessary for the fair presentation of the financial
         statements have been included, and the financial statements present
         fairly the financial position and results of operations for the
         interim periods presented. Operating results at June 30, 1999, and for
         the three and six months then ended are not necessarily indicative of
         the results that may be expected for the year ended December 31, 1999.
         These financial statements should be read in conjunction with the
         consolidated financial statements and notes thereto, together with
         management's discussion and analysis of financial condition and
         results of operations contained in the Company's 1998 Annual Report on
         Form 10-K for the year ended December 31, 1998.

3.       NEW ACCOUNTING PRONOUNCEMENTS

         In June 1998, the Financial Accounting Standards Board ("FASB") issued
         Statement of Financial Accounting Standard No. 133 ("SFAS 133"). This
         statement, which establishes accounting and reporting standards for
         derivative instruments and for hedging activities, is effective for
         the first quarter of fiscal years beginning after June 15, 1999. The
         Company does not currently have any items subject to disclosure
         pursuant to SFAS 133.

         During 1998, the Company adopted the provisions of AICPA Statement of
         Position 98-5, "Reporting on the Costs of Start-up Activities," which
         requires that all non-governmental entities expense costs of start-up
         activities, including pre-operating, pre-opening and organization
         activities, as the costs are incurred. The Company expenses all
         startup costs as they are incurred.


4.       COMPREHENSIVE INCOME

         During 1997, the Financial Accounting Standards Board issued SFAS No.
         130, "Reporting Comprehensive Income", which the Company adopted as of
         January 1, 1997. SFAS No. 130 requires the Company to report in their
         financial statements, in addition to its net income (loss),
         comprehensive income (loss), which includes all changes in equity
         during a period from non-owner sources including, as applicable,
         foreign currency items, minimum pension liability adjustments and
         unrealized gains and losses on certain investments in debt and equity
         securities. The Company's unrealized loss on marketable securities for
         the six months ended June 30, 1999 and the year ended December 31,
         1998 is reported in the Stockholders' Equity section of the Company's
         Condensed Consolidated Balance Sheets.


5.       RECLASSIFICATIONS

         Certain amounts included in the 1998 financial statements have been
         reclassified to conform with the 1999 financial statements.



6.       SEGMENT INFORMATION

         Effective January 1998, the Company adopted SFAS 131, "Disclosures
         about segments of an Enterprise and Related Information," which
         established revised standards for the reporting of financial and
         descriptive information about operating segments in financial
         statements.

         The Company owns and operates advanced hybrid fiber-coaxial networks
         and provides residential and business customers broadband
         communications services, including analog and digital cable
         television, local and long distance telephone, data and broadband
         carrier services ("BCS"). Data services include high-speed Internet
         access via cable modems. BCS includes local transport services such as
         local Internet transport, special access, local private line, and
         local loop services.

         While management of the Company monitors the revenue generated from
         each of the various broadband services, operations are managed and
         financial performance is evaluated based upon the delivery of multiple
         services to customers over a single network. As a result of multiple
         services being provided over a single network, many expenses and
         assets are shared related to providing the various broadband services
         to customers. Management believes that any allocation of the shared
         expenses or assets to the broadband services would be subjective and
         impractical.

The following is a discussion of the consolidated financial condition and
results of operations of the Company for the three and six months ended June
30, 1999 and certain factors that are expected to affect the Company's
prospective financial condition. The following discussion and analysis should
be read in conjunction with the financial statements and notes thereto and
other financial data included elsewhere in this Form 10-Q.

GENERAL

KNOLOGY (the "Company") offers residential and business customers Broadband
Services, including analog and digital cable television, local and long
distance telephone, high-speed Internet access service, and broadband carrier
services ("BCS"). We provide these Broadband Services using high capacity
hybrid fiber-coaxial networks that are two-way interactive. The Company owns,
operates and manages Interactive Broadband Networks in five metropolitan areas:
Montgomery, Alabama; Columbus and Augusta, Georgia; Panama City, Florida and
Charleston, South Carolina and plans to expand to additional mid-sized cities
in the southeastern United States. In addition, we provide analog cable
television services in Huntsville, Alabama and are currently upgrading the
Huntsville network to an Interactive Broadband Network, which will allow
additional Broadband Services to be offered in the Huntsville market.

KNOLOGY has been providing cable television service since 1995. The Company
began providing telephone and high-speed Internet access services in 1997 and
it initially offered BCS services in 1998. We believe our ability to provide
numerous services over the same network facilities and to bundle the services
at an attractive price, coupled with emphasis on customer service, provides a
competitive advantage.

KNOLOGY began providing cable television service by acquiring cable television
systems in Montgomery, Alabama and Columbus, Georgia in 1995 and using those
systems as a base for constructing new Interactive Broadband Networks. Since
acquiring the Montgomery and Columbus systems, we have upgraded the acquired
networks allowing us to offer additional Broadband Services.

The Company acquired a cable television system in Panama City Beach, Florida in
December 1997. Since the acquisition, we have begun upgrading the Beach Cable
system and extending the network into the Panama City metro area.

In early 1998, the Company began expansion into Augusta, Georgia and
Charleston, South Carolina by obtaining new franchise agreements with the local
governments and by constructing new Interactive Broadband Networks.

In June 1998, the Company acquired TTE Inc., a non-facilities based reseller of
local, long distance and operator services to small and medium-sized business
customers throughout South Carolina.

On October 30, 1998, the Company acquired the Cable Alabama cable television
system serving the Huntsville, Alabama area. The existing Cable Alabama plant
is being upgraded to an Interactive Broadband Network.

Operating revenues include charges earned for providing cable television, local
and long distance telephone and Internet access services, as well as
miscellaneous revenues resulting principally from converter rentals,
installation fees, franchise fees and late payment charges. Cable television
revenues consist of fixed monthly fees for basic and premium cable television
services, as well as fees from pay-per-view movies and events, such as boxing
matches and concerts, that involve a charge for each viewing. Revenues from the
Company's telephone services consist primarily of fixed monthly fees for local
service and enhanced services such as call waiting and voice mail, and usage
fees for long distance service. Revenues from Internet access services consist
primarily of fixed monthly fees for service and rental of cable modems.

The Company's operating expenses include cost of services to provide cable
television, telephone and Internet access services, selling, operating and
administrative expenses, and depreciation and amortization expense. Cable
television cost of services consist primarily of monthly fees to the National
Cable Television Cooperative and other programming providers, and are generally
based on the average number of subscribers to each program. Cost of services
related to our Internet access and telephone services include primarily costs
of Internet transport and telephone switching, interconnect and transport
charges payable to local and long distance carriers. Selling costs include the
cost of sales and marketing personnel and advertising and promotional expenses.
Operating expenses include payroll and departmental costs incurred for network
design, maintenance, monitoring and customer service. Administrative expenses
consist of corporate and subsidiary general management and administrative
costs. Depreciation and amortization includes depreciation of our Interactive
Broadband Networks and equipment, and amortization of cost in excess of net
assets and other intangible assets related to acquisitions.

The Company has been expanding its networks and adding corporate staffing
necessary to grow the business into new markets. Accordingly, our operating
expenses and capital expenditures have increased significantly and are expected
to continue to increase with the continued expansion of the existing Systems
and into new markets.

The Company has incurred net losses in each quarter since its inception, and as
of June 30, 1999, the accumulated deficit had reached $80.8 million. Management
anticipates incurring net losses during the next several years while continuing
to expand operations, and as a result of substantially increased depreciation
and amortization from the construction of the new networks and operating
expenses incurred in building

the customer base. There can be no assurance that growth in revenue or the
subscriber base will continue or that Knology will be able to achieve or
sustain profitability or positive cash flow.

REVENUES. Operating revenues increased 109.9% from $5.1 million for the three
months ended June 30, 1998 to $10.6 million for the three months ended June 30,
1999. The increased revenues are primarily due


                                       9
<PAGE>   11

to a higher number of RGU's during the three months ended June 30, 1999
compared to the same period in 1998. The additional RGU's resulted primarily
from:

         -        the extension of the Company's Broadband networks in the
                  Montgomery, Columbus and Panama City Markets,

         -        the continued growth of broadband services in the Augusta and
                  Charleston Markets, and

         -        the acquisition of TTE and Cable Alabama systems in June 1998
                  and October 1998, respectively.

EXPENSES. Operating expenses, excluding depreciation and amortization,
increased 98.8% from $7.5 million for the three months ended June 30, 1998 to
$14.8 million for the three months ended June 30, 1999. Cost of services
increased 139.2% from $2.2 million for the three months ended June 30, 1998 to
$5.2 million for the three months ended June 30, 1999. Selling, operating, and
administrative expenses increased 82.3% from $5.3 million for the three months
ended June 30, 1998 to $9.7 million for the three months ended June 30, 1999.
The increase in the Company's cost of services and operating expenses is
consistent with the growth in revenues and is a result of the expansion of the
operations and the increase in the number of employees associated with such
expansion and growth into new markets.

Depreciation and amortization increased from $1.9 million for the three months
ended June 30, 1998 to $8.3 million for the three months ended June 30, 1999.
The increase in depreciation and amortization is due to significant additions
in property, plant, equipment and intangible assets resulting from the
expansion of the Company's networks; the acquisition of the TTE and Cable
Alabama systems; and the purchase of buildings, computers and office equipment
at the corporate and subsidiary locations.

Interest expense increased from $7.1 million for the three months ended June
30, 1998 to $7.8 million for the three months ended June 30, 1999. The increase
in interest expense reflects the accrual of the interest attributable to the
Senior Discount Notes issued in October 1997.

Interest income was $2.9 million for the three months ended June 30, 1998,
compared to $386,000 for the same period in 1999 and reflects the interest
earned from the investment of certain proceeds received from the issuance of
the Senior Discount Notes in October 1997. The decrease in interest income is
due to the draw down of cash to fund planned expansion and acquisitions.

NET LOSS. The Company incurred a net loss of $8.3 million for the three months
ended June 30, 1998 compared to a net loss of $16.7 million for the three
months ended June 30, 1999. Management expects net losses to continue to
increase as the Company continues to expand its business.

REVENUES. Operating revenues increased 125.3% from $9.2 million for the six
months ended June 30, 1998 to $20.6 million for the six months ended June 30,
1999. The increased revenues are primarily due to a higher number of RGU's
during the six months ended June 30, 1999 compared to the same period in 1998.
The additional RGU's resulted primarily from:

         -        the extension of the Company's Broadband networks in the
                  Montgomery, Columbus and Panama City Markets,

         -        the continued growth of broadband services in the Augusta and
                  Charleston markets, and

         -        the acquisition of TTE and Cable Alabama systems in June 1998
                  and October 1998, respectively.

EXPENSES. Operating expenses, excluding depreciation and amortization,
increased 114.0% from $13.2 million for the six months ended June 30, 1998 to
$28.2 million for the six months ended June 30, 1999. Cost of services
increased 154.4% from $3.9 million for the six months ended June 30, 1998 to
$10.0 million for the six months ended June 30, 1999. Selling, operating, and
administrative expenses increased 96.8% from $9.2 million for the six months
ended June 30, 1998 to $18.2 million for the six months ended June 30, 1999.
The increase in the Company's cost of services and operating expenses is
consistent with the growth in revenues and is a result of the expansion of the
operations and the increase in the number of employees associated with such
expansion and growth into new markets.

Depreciation and amortization increased from $3.6 million for the six months
ended June 30, 1998 to $16.1 million for the six months ended June 30, 1999.
The increase in depreciation and amortization is due to significant additions
in property, plant, equipment and intangible assets resulting from the
expansion of the Company's networks; the acquisition of the TTE and Cable
Alabama systems; and the purchase of buildings, computers and office equipment
at the corporate and subsidiary locations.

Interest expense increased from $14.1 million for the six months ended June 30,
1998 to $15.6 million for the six months ended June 30, 1999. The increase in
interest expense reflects the accrual of the interest attributable to the
Senior Discount Notes issued in October 1997.

Interest income was $6.1 million for the six months ended June 30, 1998,
compared to $1.1 million for the same period in 1999 and reflects the interest
earned from the investment of certain proceeds received from the issuance of
the Senior Discount Notes in October 1997. The decrease in interest income is
due to the draw down of cash to fund planned expansion and acquisitions.

NET LOSS. The Company incurred a net loss of $15.4 million for the six months
ended June 30, 1998 compared to a net loss of $31.0 million for the six months
ended June 30, 1999. Management expects net losses to continue to increase as
the Company continues to expand its business.


LIQUIDITY AND CAPITAL RESOURCES.

As of June 30, 1999, the Company had net working capital of $9.3 million,
compared to $52.7 million at December 31, 1998.

The Company has required significant capital for operating and investing
activities in the development of its business. The Company's operating
activities provided cash of $5.1 million and used cash of $8.7 million for the
six months ended June 30, 1998 and 1999, respectively. Cash used in operating
activities in the 1999 period was primarily due to a net loss and changes in
receivables, partially offset by depreciation and amortization and bond
accretion on the Senior Discount Notes. The Company's investing activities used
cash of $8.2 million and provided cash of $3.9 million for the six months ended
June 30, 1998 and 1999, respectively. The Company's investing activities in the
1999 period primarily consisted of $45.5 million of capital expenditures
principally funded by $49.3 million in proceeds from the sale of short-term
investments. The short-term investments sold represent a portion of the proceeds
received from the October 22, 1997 offering of Senior Discount Notes that were
invested in marketable securities.

On October 22, 1997, the Company received net proceeds of approximately $242.4
million from the offering of Senior Discount Notes (the "Offering"). The Notes
were sold at a substantial discount from their principal amount at maturity and
there will not be any payment of interest on the Notes prior to April 15, 2003.
The Notes will fully accrete to face value of $444.1 million on October 15,
2002. From and after October 15, 2002, the Notes will bear interest, which will
be payable in cash, at a rate of 11-7/8% per annum on April 15 and October 15
of each year, commencing April 15, 2003. The Indenture contains covenants that
affect, and in certain cases significantly limit or prohibit, among other
things, the ability of the Company to incur indebtedness, pay dividends, prepay
subordinated indebtedness, redeem capital stock, make investments, engage in
transactions with stockholders and affiliates, create liens, sell assets and
engage in mergers and consolidations. If the Company fails to comply with these
covenants, the Company's obligation to repay the Notes may be accelerated.
However, these limitations are subject to a number of important qualifications
and exceptions. In particular, while the Indenture restricts the Company's
ability to incur additional indebtedness by requiring compliance with specified
leverage ratios, it permits the Company and its subsidiaries to incur an
unlimited amount of indebtedness to finance the acquisition of equipment,
inventory and network assets and to secure such indebtedness, and to incur up
to $50 million of additional secured indebtedness. Upon a "Change of Control"
of the Company (as defined in the Indenture), the Company would be required to
make an offer to purchase the Notes at a purchase price equal to 101% of their
accreted value, plus accrued interest.

In connection with the Senior Discount Notes Offering, the Company completed an
equity private placement, in which the Company issued approximately 21,400
additional shares of Preferred Stock at $1,500 per share for aggregate proceeds
of approximately $32.2 million.

On December 22, 1998, the Company entered into a $50 million four-year senior
secured credit facility with First Union National Bank and First Union Capital
Markets Corp. The Credit Facility allows the Company to borrow up to five times
certain individual subsidiary's annualized "consolidated adjusted cash flow"
(as defined in the Credit Facility agreement). The maximum amount currently
available under the Credit Facility is approximately $25 million, assuming
compliance with all of the operating and financial covenants. The Credit
Facility may be used for working capital and other purposes, including capital
expenditures and permitted acquisitions. At the Company's option, interest will
accrue based on either the Alternate Base Rate plus applicable margin or the
LIBOR rate plus applicable margin. The applicable margin may vary from .50% to
2.50% based on the leverage ratio of the Company. The Credit Facility contains
a number of covenants including, among others, covenants limiting the ability
of the Company and its subsidiaries to incur debt, create liens, pay dividends,
make distributions or stock repurchases, make certain investments, engage in
transactions with affiliates, sell assets, and engage in mergers and
acquisitions. The Credit Facility also includes covenants requiring compliance
with certain operating and financial ratios on a consolidated basis, including
the number of revenue generating units and average revenue per subscriber. The
Company is currently in compliance with these covenants, however, there are no
assurances that the Company will remain in compliance through the end of the
year. Should the Company not be in compliance with the covenants, the Company
will not be able to draw funds under the Credit Facility without a waiver from
the lender. To date, no funds have been drawn against the Credit Facility.

The Company's business requires substantial investment to finance capital
expenditures and related expenses to expand and/or upgrade the Interactive
Broadband Networks, to fund subscriber equipment, to fund operating losses and
to maintain the quality of its networks. The Company currently expects to spend
approximately $88 million for capital expenditures during 1999, including the
planned expansion and/or upgrade of the Montgomery, Columbus, Panama City,
Augusta, Charleston and Huntsville networks, and approximately $9 million to
fund operating losses. Failure to have access to additional funds during 1999
could require the Company to delay some of its construction plans and possibly
require the Company to constrain certain operations. However, the Company
believes that funding needed in excess of current cash reserves, internally
generated cash flow and any funds available under the Credit Facility may be
obtained by raising capital with additional equity or debt transactions during
1999. The Company currently expects to seek to raise capital, in addition to
any funds available under the Credit Facility, although there is no assurance
that such outside financing could be obtained on terms favorable to the
Company.

The Company presently estimates the cost of constructing networks and funding
initial subscriber equipment in additional new cities at approximately $50 to
$75 million per city. The actual costs may vary significantly from this range
and will depend in part on the number of miles of network to be constructed,
the geographic and demographic characteristics of the city, other factors
affecting construction costs, costs associated with the cable franchise in each
city, the number of subscribers, the mix of services purchased, the cost of
subscriber equipment paid for or financed by the Company and other factors. The
Company will need additional financing to expand into additional cities for new
business activities or in the event it decides to make additional acquisitions.


YEAR 2000

The term "Year 2000 issue" is a general term used to describe the various
problems that may result from the improper processing of dates and
date-sensitive calculations by computers and other machinery as the year 2000
is approached and reached. These problems generally arise from the fact that
most of the world's computer hardware and software have historically used only
two digits to identify the year in a date, often meaning that the computer will
fail to distinguish dates in the "2000's" from dates in the "1900's." These
problems may also arise from other sources as well, such as the use of special
codes and conventions in software that make use of the date field.




STATE OF READINESS

The Company established a Year 2000 Program Office to coordinate appropriate
activity and report to the executive management and the Board of Directors on a
continuing basis with regard to the Year 2000 issue. The Year 2000 Program
Office has implemented a comprehensive plan (the "Year 2000 Plan") for the
Company to become Year 2000 ready by the middle of the fourth quarter 1999. The
Year 2000 Plan covers the following Company systems (collectively, the
"Systems"):

         -        business-critical information technology and operating
                  systems ("Critical IT Systems") which are comprised
                  substantially of commercial off-the-shelf software and other
                  third party software and hardware relating to, among others;
         -        billing of cable, telephone and Internet services;
         -        customer service;
         -        financial operations and reporting, including accounts
                  payable;
         -        materials management;
         -        network monitoring;
         -        non-critical information technology and operating systems
                  ("Non-Critical IT Systems") which also are substantially
                  comprised of commercial off-the-shelf software and other
                  third party software and hardware relating to, among others,
                  spreadsheet, word


                                      13

                  processing, Internet intra-corporate communications and
                  supporting and related operating systems;

         -        the systems of the major vendors, third party network service
                  providers and other material service and content providers
                  ("Third Party Systems") which include, without limitation,
                  cable content providers, network long distance telephone
                  carrier providers and telephony switching services; and

         -        non-information technology systems, including the external
                  customer network, cable and telephone delivery systems
                  embedded technology ("Non-IT Systems") relating to, among
                  others, security systems and HVAC.


The Year 2000 Plan consists of six phases: (i) awareness, (ii) assessment,
(iii) remediation (whether by upgrade or replacement), (iv) testing and
validation, (v) implementation and (vi) creation of contingency plans in the
event of year 2000 failures. The Company has completed the awareness,
assessment and contingency plan phases of its Year 2000 Plan for all the
Critical IT Systems, the Non-Critical IT Systems, and the Non-IT Systems. The
Company has substantially completed the remediation, the testing and the
validation, and the implementation phases for the Critical IT Systems, the
Non-Critical IT Systems and the Non-IT Systems. Certain actions in the
remediation phase have been conducted by the third parties who provide
software, hardware or services that comprise the Systems. The Company has
polled all the third parties who provide material hardware, software, or
services as part of its Critical and Non-Critical IT Systems, with regard to
each of such third party's Year 2000 compliance plan and state of readiness.
Responses have been actively sought from all vendors and third parties as to
Year 2000 compliance, status of plans and readiness. All key vendors have
responded and most of the third parties have assured the Company that their
hardware and/or software is currently, or will be Year 2000 compliant before
the end of the year. The Company expects to have any remaining non-compliant
systems in compliance before the end of 1999.

A Year 2000 Contingency Planning Committee was formed and developed Y2K
Contingency plans for all Critical IT and Non-IT Systems and for each of the
Company's Locations. Key business risks were identified and used to drive the
development of these plans. Additionally, an outside consulting service has
been retained to assist in Year 2000 readiness, project coordination and the
execution of the Year 2000 Plan to completion.

Interstate Telephone Company, Inc. and Valley Telephone Company, Inc., each a
wholly-owned subsidiary of the Company's majority stockholder, ITC Holding
Company, Inc., have informed Knology's management that with the exception of
the one critical IT system still being tested, that each will be Y2K ready by
the 4th quarter. The Company depends on Interstate Telephone Company, Inc. and
Valley Telephone Company, Inc. for its telephony carrier access billing,
customer care and billing, and switching services. Both companies rely on third
party vendors for the telephony customer care and billing, and switching
services and both use a legacy system for telephony carrier access billing
services. The legacy system used in connection with telephony carrier access
billing has completed the remediation phase and is in the process of being
tested. Knology is working with both companies to monitor their year 2000 plans
and to prepare contingency arrangements, if necessary. Although revenues
derived from the Company's telephony services currently comprise a small
percentage of total revenues, the failure to timely remedy any year 2000
problems and/or develop a viable contingency plan could result in the temporary
inability to provide telephony services to customers, and have a material
adverse effect on the business, operations or financial results of the Company.
In addition, a material Year 2000 problem with any of the Company's major
vendors could interrupt its ability to provide cable, telephone or Internet
services to its customers.

The scheduled commencement and completion dates for each of the phases of the
Year 2000 Plan are based upon management's good faith estimates and may be
updated or revised as additional information becomes available.

COSTS

To date, approximately $450,000 of costs have been incurred in connection with
the Year 2000 Plan and the Company anticipates spending approximately $150,000
in additional funds on costs related to the Year 2000 Plan. Future costs will
include, among others, upgrades or replacements of hardware and software, and
implementation of contingency plans. The Company expenses all costs associated
with the Year 2000 Plan as they are incurred and anticipates funding the costs
of the Year 2000 Plan from cash flows. To date, no specific IT project has been
deferred due to the costs of the Year 2000 Plan.

RISKS

The failure to remediate a material Year 2000 problem or implement a viable
contingency plan could result in an interruption in, or a failure of, certain
normal business activities or operations. Such failures could materially and
adversely affect the Company's business, financial condition and results of
operations.

CONTINGENCY PLANS

The Company has developed complete contingency plans that address its most
reasonably likely worst case Year 2000 scenarios and has determined the
material risks associated with this scenario.
