             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   unaudited

1. Basis of Presentation

  The accompanying unaudited condensed consolidated financial statements 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 annual financial statements. In the opinion of management, all adjustments
(consisting only of normal recurring accruals) considered necessary for a fair
presentation have been included. The results for the interim periods presented
are not necessarily indicative of the results that may be expected for any
future period. The following information should be read in conjunction with
the financial statements and notes thereto included in EarthWeb's annual
report for the year ended December 31, 1998.

2. Use of Estimates

  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the condensed consolidated
financial statements and accompanying notes. Actual results could differ from
these estimates.

3. Acquisitions

  In February 1999, EarthWeb Inc. (EarthWeb or the Company) acquired D&L
Online, Inc., now known as EW Career Solutions, Inc., for a total base
purchase price of approximately $35.0 million in the form of cash and common
stock. Additional consideration payable in a combination of cash and stock of
up to $12.0 million may be given, contingent on future performance. In April
2000, $4.0 million of this additional consideration is expected to be paid in
a combination of cash and stock. In March 1999, EarthWeb acquired MicroHouse
International, Inc., now known as EW Subscription Services, Inc., for
approximately $9.0 million in the form of cash, common stock and a convertible
note payable issued at a discount on the date of acquisition. In addition,
EarthWeb assumed $1.7 million in debt as part of the acquisition. The
following unaudited pro forma summary presents consolidated results of
operations for the Company as if the acquisitions of EW Career Solutions, Inc.
and EW Subscription Services, Inc. had been consummated on January 1, 1998.
The unaudited pro forma information does not necessarily reflect the results
that would have been achieved, nor is it necessarily indicative of future
consolidated results of the Company.

  In July 1999, EarthWeb acquired the website SysOpt.com, an online service
which provides information on computer hardware products. In August 1999,
EarthWeb acquired the website Codeguru.com, an online service for Windows
programmers. The aggregate base purchase price for both was approximately
$12.0 million, payable in the form of common stock, cash and a convertible
note payable. Additional consideration in the form of cash or stock, with an
aggregate value of up to approximately $6.0 million may be required to be paid
if certain contingencies are met. Such amounts would be payable through 2002.
The historical revenues and expenses for the nine months ended September 30,
1998 and 1999 of these acquired websites were insignificant compared to
EarthWeb's results of operations. Intangibles related to these acquisitions
are being amortized over a three year period and are expected to result in an
additional charge of approximately $4.0 million per year. Amortization of
these intangibles for the year ended December 31, 1999 is expected to be
approximately $1.3 million of which approximately $327,000 has been included
in the third quarter ended September 30, 1999.

Item 2. Management's Discussion and Analysis of Financial Condition and
Results of Operations

  The following discussion of the financial condition and results of
operations of EarthWeb should be read in conjunction with the Management's
Discussion and Analysis of Financial Condition and Results of Operations and
the Consolidated Financial Statements and the Notes thereto included in the
Company's Annual Report for the year ended December 31, 1998. This quarterly
report on Form 10-Q contains 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
involve risks and uncertainties and actual results could differ materially
from those discussed in the forward-looking statements. All forward-looking
statements and risk factors included in this document are made as of the date
hereof, based on information available to EarthWeb as of the date thereof, and
EarthWeb assumes no obligation to update any forward-looking statement or risk
factors.

Results of Operations

  Revenues. Revenues for the three and nine months ended September 30, 1999
were $8.7 million and $19.6 million, respectively versus $944,000 and $1.9
million for the three and nine months ended September 30, 1998. Advertising
revenues including paid listings, banners and sponsorships represented 83% and
86% of total revenues for the quarter and nine months ended September 30, 1999
compared to 94% of total revenues for both the quarter and nine months ended
September 30, 1998. The increases in revenues were primarily due to growth in
advertising revenues, attributable to the acquisition of EW Career Solutions,
Inc. and increases in the volume of advertising sold resulting from increases
in the number of advertising customers. The net impact on advertising revenues
from the acquisition of EW Career Solutions, Inc. for the three and nine
months ended September 30, 1999 was an increase of approximately $4.4 million
and $10.0 million, respectively. For the quarter ended September 30, 1999, no
customer accounted for more than 10% of revenues while two customers accounted
for approximately 22% of revenues for the quarter ended September 30, 1998.
Barter transactions accounted for approximately 10% and 11% of revenues for
the quarter and nine months ended September 30, 1999 and 25% of revenues for
the quarter and nine months ended September 30, 1998, respectively. The
decrease as a percentage of revenue is primarily due to the increased revenues
from acquired companies that do not engage in significant barter transactions.
For both periods, barter advertising revenues primarily related to the
exchange of advertisements, tradeshow booths, and other promotional activities
with other companies.

  Cost of Revenues. Cost of revenues consists primarily of employee salaries
and related expenses, consulting fees, royalties, Internet access and hosting
fees, computer systems related expenses and freelance writing costs required
to support and deliver EarthWeb's online services. Cost of revenues for the
three and nine months ended September 30, 1999 were $3.1 million and $7.1
million, respectively, both representing 36% of total revenues as compared to
$601,000 and $1.4 million for the three and nine months ended September 30,
1998, which represented 64% and 73% of total revenues. The absolute dollar
increase in cost of revenues was primarily attributable to increased employee
salaries and related expenses, consulting fees, royalties and computer systems
related expenses due to the expansion of EarthWeb's online service offerings
of which approximately $1.4 million and $2.6 million related to the expenses
of EW Career Solutions, Inc. and EW Subscription Services, Inc. for the three
and nine months ended September 30, 1999, respectively. Management expects
cost of revenues to increase in absolute dollars in future periods due to the
growth of EarthWeb's business.

  Product Development Expenses. Product development expenses consist primarily
of employee salaries and related expenses, consulting fees and computer
systems related expenses required to support the development of new or
enhanced service offerings. Product development expenses for the three and
nine months ended September 30, 1999 were $1.4 million and $3.0 million,
respectively, representing 16% and 15% of total revenues as compared to
$434,000 and $990,000 for the three and nine months ended September 30, 1998,
which represented 46% and 52% of total revenues. The increase in product
development expenses was primarily attributable to the expansion of EarthWeb's
online service and product offerings and certain professional fees associated
with the evaluation of proposed acquisition targets.

  Sales and Marketing Expenses. Sales and marketing expenses consist primarily
of advertising (including expenses recorded for barter transactions), employee
salaries, commissions and related expenses of EarthWeb's sales force and
marketing personnel, promotional materials and trade show exhibition expenses.
Sales and marketing expenses for the three and nine months ended September 30,
1999 were $7.0 million and $19.0 million, respectively, representing 81% and
97% of total revenues as compared to $1.1 million and $1.9 million for the
three and nine months ended September 30, 1998, which represented 115% and 99%
of total revenues. The increases in the quarter and nine months ended
September 30, 1999, were primarily attributable to increases in advertising
expenses of approximately $3.1 million and $9.2 million, respectively, of
which approximately $1.1 million and $2.8 million related to the expenses of
EW Career Solutions, Inc. and EW Subscription Services, Inc. Additionally,
salaries, commissions and related costs increased approximately $1.8 million
and $5.3 million for the quarter and nine months ended September 30, 1999,
respectively, due to the expansion of the sales force of which $929,000 and
$2.1 million related to the expenses of both EW Career Solutions, Inc. and EW
Subscription Services, Inc. Management expects sales and marketing expenses to
increase due to the continuing growth of its sales force and its planned
increase in advertising and promotional activities.

  General and Administrative Expenses. General and administrative expenses
consist primarily of employee salaries and related expenses for executive,
administrative, and accounting personnel, facility costs, recruiting fees and
professional fees. General and administrative expenses for the three and nine
months ended September 30, 1999 were $2.4 million and $7.0 million,
respectively, representing 28% and 36% of total revenues as compared to
$914,000 and $2.2 million for the three and nine months ended September 30,
1998, which represented 97% and 117% of total revenues. The absolute dollar
increase in general and administrative expenses was primarily attributable to
increased employee salaries and related expenses, facility costs, recruiting
fees and professional fees due to the growth of our business and our operation
as a public company of which approximately $763,000 and $2.2 million related
to the expenses of EW Career Solutions, Inc. and EW Subscription Services,
Inc. for the three months and nine months ended September 30, 1999,
respectively. Management expects general and administrative expenses to
increase in future periods due to the growth of EarthWeb's business.

  Depreciation. Depreciation consists primarily of depreciation of property
and equipment. Depreciation for the three and nine months ended September 30,
1999 was $453,000 and $1.1 million, respectively, both representing 5% of
total revenues as compared to $170,000 and $519,000 for the three and nine
months ended September 30, 1998, which represented 18% and 27% of total
revenues. The increase was primarily a result of additional depreciation due
to purchases of fixed assets. Management expects depreciation to increase in
future periods due to the growth of EarthWeb's business.

  Amortization. Amortization consists primarily of amortization of intangible
assets related to acquisitions. Amortization for the three and nine months
ended September 30, 1999 were $3.5 million and $8.0 million, respectively,
both representing 41% of total revenues as compared to $141,000 and $268,000
for the three and nine months ended September 30, 1998, which represented 15%
and 14% of total revenues. The increases in the quarter and nine months ended
September 30, 1999 were primarily a result of the amortization of intangible
assets of approximately $3.0 million and $7.1 million, respectively recorded
upon the acquisitions of EW Career Solutions, Inc. and EW Subscription
Services, Inc.

  Interest and Other Income, Net. Interest and other income, net consists
primarily of interest earned on cash and cash equivalents. Interest and other
income, net for the three and nine months ended September 30, 1999 were
$258,000 and $651,000, respectively, both representing 3% of total revenues as
compared to $42,000 and $120,000 for the three and nine months ended September
30, 1998, which represented 4% and 6% of total revenues. The increase was
primarily the result of higher average cash balances during 1999, primarily
from the proceeds of EarthWeb's public offerings in November of 1998 and May
of 1999.

  Income Taxes. No provision for federal and state income taxes has been
recorded as EarthWeb has incurred net operating losses through September 30,
1999. Given EarthWeb's limited operating history, losses incurred to

                                       9
<PAGE>

date and the difficulty in accurately forecasting EarthWeb's future results,
management does not believe that the related deferred income tax assets meets
the realization criteria required by generally accepted accounting principles
and, accordingly, a full valuation allowance has been recorded.

Liquidity and Capital Resources

  EarthWeb historically has satisfied its cash requirements primarily through
offerings of common stock and convertible preferred stock and lease financing.

  Net cash used in operating activities was $10.5 million for the nine months
ended September 30, 1999 and $3.9 million for the nine months ended September
30, 1998. Cash used in operating activities for 1999 resulted primarily from a
net loss of $24.9 million offset by depreciation and amortization of $9.1
million, increases in accounts payable and accrued expenses of $4.4 million
and other current liabilities of $1.2 million. Cash used in operating
activities for 1998 resulted primarily from a net loss of $5.3 million offset
by depreciation and amortization of $788,000 and increases in accounts payable
and accrued expenses of $1.1 million.

  Net cash used in investing activities for the six months ended September 30,
1999 of $11.3 million was primarily attributable to acquisitions of $8.1
million and purchases of fixed assets of $2.9 million. Net cash used in
investing activities of $1.9 million for 1998 was primarily attributable to
purchases of fixed assets of $844,000, payments on obligations related to
acquisitions of Web sites of $1.3 million, offset by the release of restricted
cash of $225,000.

  Net cash from financing activities was $25.6 million and $3.7 million for
the nine months ended September 30, 1999 and 1998, respectively. On May 7,
1999, the Company completed a secondary public offering of 1,300,000 shares of
Common Stock at an offering price of $37.00 per share, of which 750,000 shares
were sold by the Company and 550,000 shares were sold by selling stockholders.
Proceeds to the Company, net of issuance costs, were approximately $25.4
million. The Company expects to use the net proceeds for general corporate
purposes, including expansion of sales and marketing capabilities, possible
strategic acquisitions or investments, international expansion, technical
upgrades of internal systems and working capital requirements. In June 1998,
EarthWeb issued 436,446 shares of common stock to EarthWeb LLC through a
private placement, in consideration of net proceeds of $3.7 million of which
$3.1 million was received in June and the balance received in July 1998.

  EarthWeb will continue to evaluate possible acquisitions of, or investments
in, business products and technologies that are complementary to those of
EarthWeb, which may require the use of cash. Management believes that existing
cash balances, will be sufficient to meet anticipated cash requirements for at
least the next twelve months; however, EarthWeb may sell additional equity or
debt securities or obtain credit facilities. The sale of additional securities
could result in dilution to EarthWeb's stockholders.

Year 2000

  The Year 2000 issue involves the potential for system and processing
failures of date-related data resulting from computer-controlled systems using
two digits rather than four to define the applicable year. For example,
computer programs that contain time-sensitive software may recognize a date
using two digits of "00" as the year 1900 rather than the year 2000. This
could result in system failure or miscalculations causing disruptions of
operations, including, among other things, a temporary inability to process
transactions, send invoices or engage in similar ordinary business activities.

  EarthWeb believes that its internal software and hardware systems will
function properly with respect to dates in the year 2000 and thereafter and
has completed its internal IT and non-IT assessment. Nonetheless, there can be
no assurance in this regard until such systems are operational in the year
2000. EarthWeb has contacted

                                      10
<PAGE>

all of its significant suppliers to determine the extent to which EarthWeb's
systems are vulnerable to those third parties' failure to make their own
systems Year 2000 compliant. EarthWeb was informed by such suppliers that
their systems are Year 2000 compliant. Additionally, any Year 2000 problems
experienced by EarthWeb's advertising customers could affect the placement of
advertisements on EarthWeb's online services. In the event any of EarthWeb's
suppliers or vendors prove not to be Year 2000 compliant, EarthWeb believes
that it could find a replacement vendor or supplier which is Year 2000
compliant without significant delay or expense. However, if substantially all
of EarthWeb's suppliers and vendors prove not to be Year 2000 compliant and if
EarthWeb experiences difficulties in finding replacement vendors, then, as a
result, EarthWeb's business could be materially adversely affected. The
failures to correct material Year 2000 problems by EarthWeb's suppliers and
vendors could result in an interruption in, or a failure of, certain normal
business activities or operations of EarthWeb. Such failures could materially
and adversely affect EarthWeb's results of operations, liquidity and financial
condition. Due to the general uncertainty inherent in the Year 2000 problem,
resulting from the uncertainty of the Year 2000 readiness of third-party
suppliers and vendors, EarthWeb is unable to determine at this time whether
the consequences of Year 2000 failures will have a material impact on
EarthWeb's results of operations, liquidity or financial condition.

  To date, EarthWeb has spent an immaterial amount on Year 2000 compliance
uses and expects to incur no significant costs in the future of Year 2000
problems.
