                           TELEMATE.NET SOFTWARE, INC.
                          NOTES TO FINANCIAL STATEMENTS
                                  (UNAUDITED)

1.       Basis of Presentation

                  The accompanying unaudited financial statements have been
         prepared in conformity with generally accepted accounting principles
         for interim financial statements. Accordingly, certain information or
         footnote disclosures normally included in complete financial statements
         prepared in accordance with generally accepted accounting principles
         have been condensed, or omitted, pursuant to the rules and regulations
         of the Securities and Exchange Commission. In the opinion of
         management, the statements include all adjustments necessary (which are
         of a normal and recurring nature) for the fair presentation of the
         results of the interim periods presented. These financial statements
         should be read in conjunction with the audited financial statements for
         the year ended December 31, 1998, included in the Company's
         registration statement on Form S-1 declared effective by the Securities
         and Exchange Commission on September 28, 1999. Operating results for
         the three and nine months ended are not necessarily indicative of the
         results which may be expected for the year ended December 31, 1999.

2.       Shareholders' Equity (Deficit)

                  On October 4, 1999, Telemate.Net Software, Inc. (the
         "Company") completed an initial public offering ("IPO") of 3,500,000
         shares including 3,284,000 newly issued shares sold by the Company


                                      -5-
<PAGE>   6

         and 216,000 outstanding shares sold by existing shareholders. The IPO
         generated net proceeds to the Company of approximately $42.8 million
         before IPO expenses. Because this transaction did not close until after
         September 30, 1999, it is not reflected in the September 30, 1999
         financial statements. Had the transaction been completed prior to
         September 30, 1999, the balance of cash and cash equivalents would
         have been approximately $43.0 million and shareholders' equity,
         including the effect of the conversion of preferred stock to common
         stock associated with the IPO, would have been approximately $42.0
         million. In addition, certain expenses related to the IPO have been
         recorded in other assets and generally are included in accounts payable
         or accrued expense. These IPO expenses will be netted against the
         proceeds.

                  Subsequently, pursuant to the underwriters' exercise of their
         over-allotment option, selling shareholders sold an additional 100,000
         outstanding shares and the Company sold an additional 165,000 newly
         issued shares. The Company received $2.1 million from the proceeds of
         the sale of the 165,000 shares on November 1, 1999.

3.       Net Income (Loss) Per Share

                  The Company has presented net income (loss) per share pursuant
         to SFAS No. 128, Earnings Per Share, and the Securities and Exchange
         Commission Staff Accounting bulletin No. 98. Pursuant to SEC Staff
         Accounting Bulletin No. 98, common stock and convertible preferred
         stock issued for nominal consideration, prior to the effective date of
         the initial public offering ("IPO"), are required to be included in the
         calculation of basic and diluted net income (loss) per share, as if
         they were outstanding for all periods presented. The Company has not
         had any such issuances or grants for nominal consideration. Potentially
         dilutive securities include stock options and Series A redeemable
         convertible preferred stock.

4.       Long-Term Debt and Redeemable Stock Purchase Warrant

                  In anticipation of receipt of the proceeds from the IPO, the
         Company retired approximately $1.0 million of long-term debt on
         September 29, 1999. In connection with the issuance of the $1.0 million
         note payable, the Company issued a warrant for the purchase of common
         stock at an exercise price of $.003 per share. On September 23, 1999,
         the debt holder exercised the warrant for 122,448 shares. Based on the
         fair value of $14.00 per share, the Company increased the redeemable
         stock purchase warrant and recorded a charge to interest expense of
         $883,674 in the third quarter. For the nine months ended September 30,
         1999, the Company recorded a charge to interest expense of $1,617,674
         to reflect the increased value of the warrant. Upon exercise of the
         warrant, and the Company's repayment of the debt, the warrant was no
         longer redeemable; accordingly, the redeemable stock purchase warrant
         was reclassified to common stock and additional paid in capital.


ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

                  Certain information included in this report constitutes
         forward-looking statements within the meaning of Section 27A of the
         Securities Act of 1933, as amended, and Section 21E of the Securities
         Exchange Act of 1934, as amended. These forward-looking statements
         reflect the Company's current views with respect to future events and
         financial performance, but are subject to many uncertainties and risk
         factors relating to the Company's operations and business environment
         that may cause the actual results of the Company to be materially
         different from future results expressed or implied by such
         forward-looking statements. Reference is made in particular to the
         discussion set forth below and set forth in the section entitled "Risk
         Factors" in the Company's Registration Statement on Form S-1 declared
         effective by the Securities and Exchange Commission on September 28,
         1999.

OVERVIEW

         Telemate.Net provides integrated network usage management solutions.
From our inception in 1986, through 1996, we focused exclusively on providing
call accounting software solutions. By the early 1990's, we had emerged as a
call accounting market leader by evolving our product line to meet the
functionality and price performance requirements of our customers. In 1996,
seeking to capitalize on the opportunity the Internet would present, we began
researching and developing an Internet usage management solution. In May 1997,
we released the initial version of our Internet usage management solution, which
we believe was the first such product on the market. In May 1998, we began
shipping our latest generation of Internet usage management software. In
November 1998, we introduced our integrated network usage management products,
which can be used by our customers for Internet usage management only, call
accounting only, or a combination of both.

         In 1996, our management decided to invest the cash flow from our call
accounting business in the development of an Internet usage management solution.
Our focus on developing an Internet product included sacrificing potential
profits and borrowing $1.0 million in 1998. The refocusing of our business
resulted in reduced call accounting revenue growth. From 1996 through 1998,
average annual call accounting revenue growth was 17%, which is significantly
lower than the call accounting revenue growth from 1990 through 1995. We believe
the investments we have made have positioned us for future growth in emerging
integrated network usage management market.

         Our revenue consists of product and service revenue. Our product
revenue is derived primarily from licensing our software products. We also
resell complementary hardware, which has historically accounted for less than
10% of our total annual revenue. For the three months the Company's hardware
sales represented 13.1% of revenue due to a number of large product sales
requiring an unusually high amount of hardware. These sales also resulted in
hardware accounting for 10.6% of revenue for the nine months ended September 30,
1999. We expect the hardware revenue percentage to be within our historical
range for the year. Support service revenue consists of fees paid for
maintenance services, product updates, and professional services. Maintenance
services include diagnosis and correction of errors in the current version of
the product and telephone consultation to discuss general support questions.
Product updates include error correction and minor enhancements to the product
models purchased, and periodic updates to tariff information for call accounting
products. Substantially all of our license agreements are perpetual. Support
agreements are typically for a term of one year and renew automatically upon
payment of an annual maintenance fee by the customer. This support fee typically
represents 20% of the current list price of the products licensed. Professional
services includes installation, training and custom report generation.

         We recognize revenue from software licenses in accordance with the
American Institute of Certified Public Accountants Statement of Position 97-2,
Software Revenue Recognition, Statement of Position 98-4, Deferral of the
Effective Date of a Provision of SOP 97-2 and Statement of Position 98-9,
Modification of SOP 97-2, Software Revenue Recognition, With Respect to Certain
Transactions. Revenue derived from software license fees and hardware is
recognized upon shipment. Revenue derived from software support services
primarily involves annual contracts and is recognized ratably over the service
period. Revenue related to professional services is recognized as services are
provided. Deferred revenue generally represents advance payments received from
customers and billings invoiced to customers for software support and
professional services in advance of the time revenue is recognized.

         We identify revenue as call accounting revenue or Internet/integrated
revenue based upon the types of data sources licensed and the delivery of call
accounting product features. If a customer is delivered tariff information for
all data sources they have licensed, the product revenue is identified as call
accounting. All other product revenue is identified as Internet/integrated.
Service revenue is identified based on the associated product identification.

         We sell our products through a combination of direct sales by our sales
personnel and indirect sales primarily through resellers and distributors. While
our direct sales force is expected to continue to generate a large


                                      -7-
<PAGE>   8

proportion of future revenue, we are increasingly utilizing indirect
distribution channels, such as network resellers, systems integrators and
distributors, as an important complement to our direct sales force. We expect to
grow our international distribution significantly in the next few years and have
added several European distributors this year. Distributors and resellers
purchase the product for resale at a discount from our standard price list. This
discount ranges from 20% to 65% and varies based on a number of factors
including their volume of business, whether they distribute to other resellers
and whether they provide product support.

         We also maintain relationships with leading networking and network
security product vendors that help to market and distribute our products. These
vendors assist in the sales and marketing of our products by bundling them with
their own products, selling our products through their sales forces and
promoting our products at trade shows, seminars and through their web sites. We
intend to continue to focus sales resources on strengthening existing
relationships and creating new relationships with strategic organizations.

revenue, both in absolute dollars and as a percentage of total revenue:

RESULTS OF OPERATIONS

  Three Months Ended September 30, 1999 and 1998

         Revenue. Total revenue was $3.5 million for the three months ended
September 30, 1999, representing a 28.5% increase from $2.7 million for the same
period in 1998. Total product revenue was $1.8 million, or 51.6% of total
revenue, in the three months ended September 30, 1999, representing a 27.8%
increase from $1.4 million, or 51.9% of total revenue, for the same period in
1998. Total service revenue was $1.7 million, or 48.4% of total revenue, in the
three months ended September 30, 1999, representing a 29.4% increase from $1.3
million, or 48.1% of total revenue, for the same period in 1998. The increase in
total revenue was the result of the increase in Internet/integrated product and
service revenue for the period.

         Internet/Integrated Revenue. Total Internet/integrated revenue was $1.3
million, or 37.3% of total revenue, in the three months ended September 30,
1999, representing a 262.3% increase from $359,000, or 13.3% of total revenue,
for the same period in 1998. Internet/integrated product revenue was $872,000,
or 25.0% of total revenue, in the three months ended September 30, 1999,
representing a 161.3% increase from $334,000, or 12.3% of total revenue, for the
same period in 1998. Internet/integrated service revenue was $429,000, or 12.3%
of total revenue, in the three months ended September 30, 1999, representing a
1,597.8% increase from $25,000, or 1.0% of total revenue, for the same period in
1998. The increase in Internet/integrated product revenue and the increase as a
percentage of total revenue were due to the sales of our integrated product,
which was first released in the fourth quarter of 1998. The increase in
Internet/integrated service revenue was driven by the services associated with
the increase in Internet/integrated product sales.

         Call Accounting Revenue. Total call accounting revenue was $2.2
million, or 62.7% of total revenue, for the three months ended September 30,
1999, representing a 7.2% decrease from $2.4 million, or 86.7% of total revenue
for the same period in 1998. Call accounting product revenue was $926,000, or
26.6% of total revenue, for the three months ended September 30, 1999,
representing a 13.7% decrease from $1.1 million, or 39.6% of total revenue, for
the same period in 1998. Call accounting service revenue was $1.26 million, or
36.1% of total revenue, in the three months ended September 30, 1999,
representing a 1.6% decrease from $1.28 million, or 47.1% of total revenue, for
the same period in 1998. The decline in call accounting revenue and percentage
share of total revenue in the third quarter of 1999 was due to the focus of our
sales force on selling Internet/integrated products and the conversion of call
accounting product customers to integrated product customers. The integrated
product was released in the fourth quarter of 1998.

         Cost of Product Revenue. Cost of product revenue was $402,000, or 11.6%
of total revenue, in the three months ended September 30, 1999, representing a
91.7% increase from $210,000, or 7.7% of total revenue, for the same period in
1998. This increase in cost and the corresponding increase in percentage of
revenue were primarily attributable to an increase in hardware costs related to
increased sales, and royalty payments for third-party licensing incurred since
the release of our fourth generation call accounting and integrated products in
the fourth quarter of 1998.

         Cost of Service Revenue. Cost of service revenue was $492,000, or 14.1%
of total revenue, for the three months ended September 30, 1999, representing a
51.6% increase from $324,000, or 12.0% of total revenue, for the same period in
1998. This increase was due to an increase in staff to handle the expansion of
the number of companies under annual maintenance contracts and the increase in
professional services sold.

         Research and Development Expenses. Research and development expenses
were $585,000, or 16.8% of total revenue, for the three months ended September
30, 1999, representing an 18.1% increase from $495,000, or 18.3% of total
revenue, for the same period in 1998. The increase in research and development
expenses reflects


                                      -9-
<PAGE>   10
the expansion of our use of outside contractor to accelerate the development of
our product line. In the third quarter of 1998 we were reducing our use of
contractors as we were completing the development of our initial version of our
Internet/integrated product.

         Sales and Marketing Expenses. Sales and marketing expenses were $1.7
million, or 47.7% of total revenue, for three months ended September 30, 1999,
representing a 36.7% increase from $1.2 million, or 44.9% of total revenue, for
the same period in 1998. The increase reflects higher commission expense related
to increased sales revenue, and increased compensation costs due to expansion of
the sales and marketing staff.

         General and Administrative Expenses. General and administrative
expenses were $969,000, or 27.8% of total revenue, in the three months ended
September 30, 1999, representing a 36.4% increase from $711,000, or 26.2% of
total revenue, for the same period in 1998. This increase was primarily due to
increased recruiting fees, travel expenses and compensation related charges.

         Non-cash Compensation Expenses. Non-cash compensation of $153,000, or
4.4% of total revenue, was charged in connection with stock options granted at a
price below market value, primarily to an executive officer.

Other income (expense). Other income (expense) was $62,000, or 1.8% of total
revenue, in the three months ended September 30, 1999, representing a 96.0%
increase from $32,000, or 1.2% of total revenue, for the same period in 1998.
The accelerated amortization of the balance of the initial stock purchase
warrant charge in conjunction with the repayment of the $1,000,000 loan
accounts for this increase.

Nine months Ended September 30, 1999 and 1998

         Revenue. Total revenue was $8.9 million for the first nine months of
1999, representing a 15.2% increase from $7.7 million for the same period in
1998. Total product revenue was $4.6 million, or 51.7% of total revenue, in the
first nine months of 1999, representing a 15.9% increase from $4.0 million, or
51.4% of total revenue, for the same period in 1998. Total service revenue was
$4.3 million, or 48.3% of total revenue, in the first nine months of 1999,
representing a 14.4% increase from $3.8 million, or 48.6 % of total revenue, for
the same period in 1998. The increase in total revenue was the result of the
increase in sales of Internet/integrated products and services in the first nine
months of the year.

         Internet/Integrated Revenue. Total Internet/integrated revenue was $2.3
million, or 25.7% of total revenue, in the first nine months of 1999,
representing a 232.2% increase from $689,000, or 8.9% of total revenue, for the
same period in 1998. Internet/integrated product revenue was $1.6 million, or
18.5% of total revenue, in the first nine months of 1999, representing a 156.5%
increase from $642,000, or 8.3% of total revenue, for the same period in 1998.
Internet/integrated service revenue was $641,000, or 7.2% of total revenue, in
the first nine months of 1999, representing a 1,280.3% increase from $46,000, or
0.6% of total revenue, for the same period in 1998. The increase in
Internet/integrated product revenue and the increase as a percentage of total
revenue were due to the sales of our integrated product, which was first
released in the fourth quarter of 1998. The increase in Internet/integrated
service revenue was driven by the increase in Internet/integrated product sales.

         Call Accounting Revenue. Total call accounting revenue was $6.6
million, or 74.3% of total revenue, for the first nine months of 1999,
representing a 6.1% decrease from $7.0 million, or 91.1% of total revenue for
the same period in 1998. Call accounting product revenue was $3.0 million, or
33.2% of total revenue, for the first nine months of 1999, representing a 11.2%
decrease from $3.3 million, or 43.1% of total revenue, for the same period in
1998. Call accounting service revenue was $3.7 million, or 41.1% of total
revenue, in the first nine months of 1999, representing 1.4% decrease from $3.7
million, or 48.0% of total revenue, for the same period in 1998. The decline in
call accounting revenue and percentage share of total revenue in the first nine
months of 1999 was due to the increased focus of our sales force on selling
Internet/integrated products as compared to selling call accounting only
products and an increase in the provision for product returns.


                                      -10-
<PAGE>   11

         Cost of Product Revenue. Cost of product revenue was $958,000, or 10.8%
of total revenue, in the first nine months of 1999, representing a 49.2%
increase from $642,000, or 8.3% of total revenue, for the same period in 1998.
This increase in cost and the corresponding increase in percentage of total
revenue was primarily attributable to an increase in hardware costs related to
increased sales volumes and royalty payments for third-party licensing incurred
since the release of our fourth generation call accounting and integrated
products in the fourth quarter of 1998.

         Cost of Service Revenue. Cost of service revenue was $1.2 million, or
13.5% of total revenue, for the first nine months of 1999, representing a 26.2%
increase from $951,000, or 12.3% of total revenue, for the same period in 1998.
This increase was due to an increase in staff to handle the expansion of the
number of companies under annual maintenance contracts and the increase in
professional services sold.

         Research and Development Expenses. Research and development expenses
were $1.3 million, or 15.1% of total revenue, for the first nine months of 1999,
representing a 2.3% decrease from $1.4 million, or 17.8% of total revenue, for
the same period in 1998. The decrease in total research and development
expenditures reflects the reduction in expenditures for outside contractors that
were used in 1998 to accelerate the development of our Internet/integrated
product line.

         Sales and Marketing Expenses. Sales and marketing expenses include
salaries and related costs, commissions, travel, facilities, communications
costs and promotional expenses for our sales organizations and marketing staff.
Sales and marketing expenses were $3.8 million, or 43.1% of total revenue, in
the first nine months of 1999, representing an 11.2% increase from $3.5 million,
or 44.6% of total revenue, for the same period in 1998. The increase reflects
higher commission expense related to the increased sales revenue, and increased
compensation costs due to expansion of the sales and marketing staffs.

         General and Administrative Expenses. General and administrative
expenses include administration salaries and related benefits, depreciation and
amortization , management recruiting fees, as well as legal and professional
fees. General and administrative expenses were $2.7 million, or 29.9% of total
revenue, in the first nine months of 1999, representing a 19.1% increase from
$2.2 million, or 28.9% of total revenue, for the same period in 1998. This
increase was primarily due to an increased provision for uncollectible accounts,
an increase in sales taxes, and recruiting fees.

         Non-cash Compensation Expenses. Non-cash compensation of $153,000, or
1.7% of total revenue, was charged in connection with stock options granted at a
price below market value, primarily to an executive officer.

         Other income (expense). Other income (expense) was $140,000, or 1.6% of
total revenue, for the first nine months of 1999, representing a 90.3% increase
from $73,000, or 0.9% of total revenue, for the same period in 1998. Interest
expense relating to $1,000,000 borrowed from Sirrom Investments, Inc. in March
1998 and repaid in September 1999 accounts for this increase.

         Redeemable Stock Purchase Warrant. Charges for the increase in value of
the redeemable stock purchase warrant were $1.6 million, or 18.2% of total
revenue, in the first nine months of 1999. There was no similar charge in 1998.
This charge represents the increase in the value of the warrant granted Sirrom
Investments, Inc. in connection with the $1,000,000 loan from Sirrom. The
warrant was exercised and the loan was repaid in September 1999.

LIQUIDITY AND CAPITAL RESOURCES

         Historically, we have funded our operations from cash generated from
operations and the issuance of long-term debt. We had cash and cash equivalents
of $1.0 million at September 30, 1999, and $113,000 at September 30, 1998.

         Cash provided by (used in) operating activities during the nine months
ended September 30, 1999 and September 30, 1998 was $6,000, and $(762,000),
respectively. This increase reflects the net impact of increases in our net loss
and in accounts receivable, which were offset by an increase in accounts payable
and accrued expenses, the recording of accretion of the redeemable common stock
warrant related to our loan with Sirrom Investments, Inc. and an increase in
deferred revenue.

         Our investing activities primarily include expenditures for fixed
assets in support of our product development activities and infrastructure. Net
cash used in investing activities increased to $580,000 in the nine months ended
September 30, 1999, compared to $247,000 for the same period in 1998. This
increase resulted primarily from an increase in fixed assets purchased.

         Net cash provided by financing activities was $1.6 million in
the nine months ended September 30, 1999, compared to $1.0 million for the same
period in 1998. This change was due primarily to the sale of Series A redeemable
convertible preferred stock for $6.0 million, the redemption of common stock for
$4.0 million, the repayment of the loan from Sirrom Investments, Inc. for $1.0
million, and the sale of common stock for $500,000 in the nine months ended
September 30, 1999, and the issuance of long-term debt in 1998. We also have a
$750,000 bank line of credit with Silicon Valley Bank, which expires in November
1999. As of September 30, 1999, there was $750,000 available under this line of
credit.

         Since we have not generated significant revenue from sales outside the
United States, we have not sustained material foreign currency exchange losses
and presently do not attempt to hedge our exposure to fluctuations in foreign
currency exchange rates. Should our revenue from international sales increase,
and should such sales be denominated in foreign currencies, we intend to adopt a
hedging strategy against foreign currency fluctuations.

         We believe that our existing liquidity and capital resources, including
the proceeds resulting from the sale of our common stock in the IPO, will be
sufficient to satisfy our cash requirements for at least the next 12 months.
Beyond the next 12 months, we expect income from operations and the remaining
proceeds from the IPO to provide sufficient liquidity and capital resources, and
we are not aware of any events that may cause our liquidity to increase or
decrease in a material way. However, our business strategies will require a
substantial increase in expenditures. To the extent that income from operations
is insufficient to implement our business strategies, or if we identify
additional strategic investments in our business, technology or products, we may
be required to raise additional funds through equity or debt financing. If
adequate funds are not available on acceptable terms or at all, our ability to
implement our business strategies or take advantage of unanticipated
opportunities or otherwise respond to competitive pressures would be limited.
There can be no assurance that we will be able to raise these additional funds
on terms acceptable to us, or at all.


IMPACT OF THE YEAR 2000 COMPUTER PROBLEM

         State of Readiness of our Products. All new products introduced by us
will be year 2000 compliant. We have been testing our existing products for use
in the year 2000 and beyond. The results suggest that current versions of our
products are year 2000 compliant. However, our testing does not cover every
possible computing environment. Accordingly, some customers may have year 2000
problems with products that we believe are 2000 compliant.

         Previous purchasers may be using older versions of our products. We
believe problems encountered by such users could be quickly remedied with our
year 2000 upgrades for those products. In addition, we have not


                                      -12-
<PAGE>   13
tested discontinued products for year 2000 compliance, some of which are still
in use. We have identified and attempted to inform customers that rely on such
discontinued products of their lack of compliance and are working with them to
provide alternate operating arrangements. We cannot guarantee that we will be
able to locate all users of our older, non-compliant products. Our experience in
developing year 2000 compliant versions of our existing products suggests that
we can correct year 2000 problems in our discontinued products without incurring
material expenses.

         State of Readiness of our Internal Systems. We may be affected by year
2000 issues related to non-compliant internal systems developed by us or by
third-party vendors. We have completed testing all material internal systems for
year 2000 compliance. We are not currently aware of any year 2000 problem
relating to any internal systems material to the operation of our business. We
have also received assurances from our third-party vendors for all material
systems in use by us that such systems are year 2000 compliant, except with
respect to an application for customer order tracking. We anticipate that the
non-compliant application for customer order tracking will be made year 2000
compliant or replaced before December 31, 1999.

         Our internal operations and business are also dependent upon the
computer-controlled systems of third parties such as suppliers, customers, and
service providers. We believe that absent a critical failure beyond our control,
such as a prolonged loss of electrical or telephone service, year 2000 problems
experienced by third parties will not have a material impact on us. We have no
contingency plan for critical failures in third-party products. Our contingency
plan in the event of non-critical failure is to establish relationships with
alternative suppliers or vendors to replace failed suppliers or vendors.

         Cost. We do not separately track expenditures relating to year 2000
compliance. Such expenditures are primarily absorbed with our development
organization. To date, our costs related to year 2000 compliance have not been
material relative to our overall development expenditures. Furthermore, based on
our experience to date, and our assessment that all material internal systems
other than the order tracking application and all currently marketed products
are year 2000 compliant, we do not anticipate that costs associated with
remediating our non-compliant products or internal systems will be material.

         Risks. We believe the most likely consequences of a failure by us to
make our products year 2000 compliant would be a decrease in sales of our
products, an increase in allocation of resources to address year 2000 problems
of our customers without additional revenue commensurate with such dedication of
resources, or an increase in litigation costs relating to losses suffered by our
customers due to such year 2000 problems. We believe the most likely
consequences of a failure of our internal systems or the systems of third-party
suppliers or service providers would be our inability to process orders, issue
invoices, and develop products. Should any of these problems occur, we could be
required to devote significant resources to correct them. Aside from the
possibility of having to establish relationships with alternative suppliers or
vendors to replace failed suppliers of vendors, we do not currently anticipate
having to develop a contingency plan for handling any year 2000 problems that
are not detected or corrected prior to their occurrence. Due to the general
uncertainty inherent in the year 2000 computer problem, resulting for the
uncertainty of the year 2000 readiness of third-party suppliers and vendors, we
are unable to determine at this time whether the consequences of year 2000
failures will have a material impact on our business, results or operations and
financial condition.
