              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)


1.   The Company and Basis of Presentation

     Lycos, Inc., ("Lycos" or the "Company") is a global Internet navigation and
community network that offers globally branded media properties and aggregated
content distributed primarily through the Web. Under the "Lycos Network" brand,
Lycos provides guides to online content, aggregated third-party content, Web
search and directory services and community and personalization features. Lycos
seeks to draw a large number of viewers to its Websites by providing multiple
destinations for identifying, selecting and accessing resources, services,
content and information on the Web. The Company was formed in June 1995 by
CMG@Ventures L.P., a wholly-owned subsidiary of CMGI, Inc. The Company operates
in one industry segment, generating revenue from selling advertising, electronic
commerce and licensing its products and services. The Company's fiscal year end
is July 31.

     The accompanying unaudited consolidated financial statements include the
accounts of the Company and its wholly-owned subsidiaries and have been prepared
in accordance with generally accepted accounting principles for interim
financial information and with the instructions for Form 10-Q and Article 10 of
Regulation S-X. In the opinion of management, these financial statements contain
all adjustments, consisting only of normal recurring adjustments, necessary for
a fair presentation of the results of these interim periods. Certain information
and related footnote disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted, although the Company believes the disclosures in these
financial statements are adequate to make the information presented not
misleading. These financial statements should be read in conjunction with the
Company's audited financial statements for the year ended July 31, 1998,
included in the Company's Amended Annual Report on Form 10-K/A filed with the
Securities and Exchange Commission on April 16, 1999. The results of operations
for the interim periods shown are not necessarily indicative of the results for
any future interim period or for the entire fiscal year.

Restatement Related to Acquired In-Process Technology

     The accompanying unaudited consolidated financial statements reflect a
change in the original accounting for the purchase price allocation related to
the acquisitions of Tripod, WiseWire, Guestworld and WhoWhere?. The Company has
modified the methods used to value purchased in-process research and development
in connection with the Company's acquisitions. This resulted in a reduction in
the amount of charges for in-process research and development from $106,639,000
to $17,280,000 and an increase in the amounts allocated to intangible assets
from $156,121,336 to $245,480,391. The restatement did not effect previously
reported net cash flows for any period. The Company filed an amended Form 10-K/A
and amended Forms 10-Q/A on April 16, 1999 to reflect the changes.


2.   Revenue Recognition

     The Company's advertising revenues are derived principally from short-term
advertising contracts in which the Company guarantees a number of impressions
for a fixed fee or on a per impression basis with an established minimum fee.
Revenues from advertising are recognized as the services are performed.

     Electronic commerce revenues are derived principally from "slotting fees"
paid for selective positioning and promotion within the Company's suite of
products as well as from royalties from the sale of goods and services from the
Company's Websites. The Company's license and product revenues are derived
principally from product licensing fees and fees from maintenance and support of
its products. Electronic commerce, license and product revenues are generally
recognized upon delivery provided that no significant Company obligations remain
and collection of the receivable is probable. In cases where there are
significant remaining obligations, the Company defers such revenue until those
obligations are satisfied. Fees from maintenance and support of the Company's
products including revenues bundled with the initial licensing fees are deferred
and recognized ratably over the service period.

     Deferred revenues are comprised of license and electronic commerce fees to
be earned in the future on noncancelable agreements at the balance sheet date.

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


3.   Investments

     In March 1999, the Company established Lycos Korea, Inc. as the basis for a
joint venture agreement with Mirae Corporation to create a localized version of
the Lycos Network services to be offered in Korea. The joint venture is owned
50% by Lycos and 50% by Mirae, a Korean high technology company.

4.   Comprehensive Income (Loss)

     The Company adopted Statement of Financial Accounting Standard No. 130
(SFAS 130), "Reporting Comprehensive Income" during the quarter ended October
31, 1998. SFAS 130 establishes standards for the reporting and display of
comprehensive income and its components in the financial statements.
Comprehensive income as defined includes all changes in equity during a period
from non-owner sources. Examples of items to be included in comprehensive
income, which are excluded from net income, include foreign currency translation
adjustment and unrealized gains and losses on available-for-sale securities.
Comprehensive loss was $11,526,461 and $26,386,056 for the three and nine month
periods ended April 30, 1999, respectively. The difference between net loss and
comprehensive loss for the three and nine months ended April 30, 1999 is due to
$1,775,631 and $4,264,619, respectively of unrealized gains on the Company's
remaining investment in Amazon.com, which is classified as an available-for-sale
investment under SFAS 115. The Company had no "other comprehensive income" items
in the three and nine month periods ended April 30, 1998.

5.   Business Combinations

Acquisition of WhoWhere? Inc.

     On August 7, 1998, the Company entered into an Agreement and Plan of Merger
with WhoWhere? Inc., a California corporation ("WhoWhere?"), and certain
shareholders of WhoWhere?. On August 13, 1998, the Company completed the closing
of the merger and WhoWhere? became a wholly-owned subsidiary of the Company. As
a result of a subsequent modification in the Company's original methods used to
value purchased in-process research and development in connection with the
Company's acquisitions, the total purchase price of approximately $160 million
was entirely allocated to developed technology, goodwill and other intangible
assets which are amortized over a period of five years.

     Pro forma financial information for the nine months ended April 30, 1999 is
not materially different than the Company's actual consolidated results as
reported, which do not include the operations of WhoWhere for the twelve days
from August 1, 1998 to August 12, 1998. Unaudited combined pro forma financial
information for the three months ended April 30, 1998, assuming the WhoWhere?
acquisition had occurred on August 1, 1997, would have resulted in net revenues
of $17.2 million, net loss of $23.9 million, and basic and diluted net loss per
share of $0.68. Unaudited combined pro forma financial information for the nine
months ended April 30, 1998, assuming the WhoWhere? acquisition had occurred on
August 1, 1997, would have resulted in net revenues of $41.1 million, net loss
of $26.9 million, and basic and diluted net loss per share of $0.81. The pro
forma net loss includes amortization of developed technology, goodwill and other
intangible assets of $10.3 million and $26.6 million for the three and nine
months ended April 30, 1998, respectively. The unaudited pro forma information
is for illustrative purposes only and is not necessarily indicative of the
actual results of operations had the acquisition occurred on August 1, 1997, nor
the results of any future period.

Acquisition of Wired Ventures, Inc.

     On October 5, 1998, the Company entered into a definitive merger agreement
to acquire Wired Ventures Inc. ("Wired") in a stock-for-stock transaction. The
transaction will be accounted for under the purchase method of accounting, and
accordingly, the purchase price will be allocated to assets acquired and
liabilities assumed based on their respective fair values. Intangible assets
will be amortized over a period of five years. The merger is subject to several
conditions, including Wired's shareholder approval and customary regulatory
approvals. The Company has filed a Registration Statement on Form S-4, which is
pending the approval of the Securities and Exchange Commission, with respect to
the registration of the shares of Lycos Common Stock to be issued in the merger.

5.   Business Combinations (continued)

     Additional information with respect to the proposed transaction is
available on Form S-4 filed with the Securities and Exchange Commission on
November 25, 1998 as amended on February 2, 1999, April 16, 1999 and May 20,
1999.

6.   Reclassifications

     Certain amounts in the three and nine months ended April 30, 1998 have been
reclassified to permit comparison to the current periods presented.

7.   Litigation

     The Company is subject to several purported class action lawsuits. The
complaints allege, among other claims, violations of the United States federal
securities law through alleged misrepresentations relating to the Company's
agreement to enter into an announced transaction with USA Networks, Inc. and
certain affiliated companies. Each complaint seeks an unspecified award of
damages. The Company believes that the allegations in the complaints are without
merit and intends to contest them vigorously.

8.   Subsequent Events

     On May 12, 1999, Lycos, Inc. and USA Networks, Inc. jointly announced a
mutual consent to terminate the merger agreement between Lycos, USA Networks and
Ticketmaster Online-CitySearch. The option agreement between USA Networks and
Lycos that was part of the merger agreement was also terminated. The termination
agreement requires Lycos to pay USAi (Home Shopping Network, Ticketmaster and
First Auction) and TMCS (Ticketmaster Online-CitySearch, Inc.) an aggregate of
$35 million under certain circumstances if prior to July 15, 1999 Lycos enters
into an agreement with respect to, or becomes subject to, certain acquisition
proposals. In addition, subject to certain exceptions, USAi and TMCS each has
agreed that until July 15, 1999, it will not acquire Lycos stock or make any
proposals to acquire Lycos. The Company expects to write-off acquisition costs
paid by Lycos relating to this transaction in the fourth quarter of 1999.

     On May 18, 1999, the Board of Directors of the Company approved a 2-for-1
common stock split. The split is subject to shareholder approval of an amendment
to the Company's Certificate of Incorporation to increase the Company's
authorized common stock. The Company anticipates the split to become effective
in late July 1999.

     On June 8, the Company announced the relocation of all Lycos Pittsburgh
functions and responsibilities to corporate headquarters in Waltham. This
relocation is expected to be completed in the second quarter of 2000. The cost
of this relocation will be recorded in the fourth quarter of 1999.

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

     The matters discussed in this report contain forward-looking statements
that involve risks and uncertainties. The Company's actual results could differ
materially from those discussed herein. Factors that could cause or contribute
to such differences include, but are not limited to, those discussed in this
section and elsewhere in this Report, and the risks discussed in the "Factors
Affecting the Company's Business, Operating Results and Financial Condition"
section included in the Company's Amended 1998 Annual Report on Form 10-K/A
filed with the Securities and Exchange Commission on April 16, 1999.


Results of Operations

Restatement Related to Acquired In-Process Technology

     The accompanying unaudited consolidated financial statements reflect a
change in the original accounting for the purchase price allocation related to
the acquisitions of Tripod, WiseWire, Guestworld and WhoWhere?. The Company has
modified the methods used to value purchased in-process research and development
in connection with the Company's acquisitions. This resulted in a reduction in
the amount of charges for in-process research and development from $106,639,000
to $17,280,000 and an increase in the amounts allocated to intangible assets
from $156,121,336 to $245,480,391. The restatement did not effect previously
reported net cash flows for any period. The Company filed an amended Form 10-K/A
and amended Forms 10-Q/A on April 16, 1999 to reflect the changes.

     Total Revenues   Total revenues for the three and nine months ended April
30, 1999 were $35.1 million and $90.4 million versus $15.1 million and $37.1
million for the three and nine months ended April 30, 1998, as a result of
growth in the number of advertisers and electronic commerce partners. As of
April 30, 1999, deferred revenues, including billings in excess of revenues,
increased to $148.0 million, compared to $57.6 million at July 31, 1998,
attributable to increases in advertising contracts and guaranteed commitments
under electronic commerce agreements for which there are significant obligations
of the Company remaining.

     Advertising Revenues   Advertising revenues were $23.6 million and $61.8
million for the three and nine months ending April 30, 1999, representing 67%
and 68% of total revenues, as compared to advertising revenues of $11.7 million
and $27.7 million for the three and nine months ended April 30, 1998, which
represented 77% and 75% of total revenues. The top ten customers accounted for
16% of advertising revenues in the quarter ended April 30, 1999 as compared to
20% of advertising revenues in the quarter ended April 30, 1998.

     The Company currently derives a substantial portion of its revenues from
the sale of advertisements on its Websites, primarily through banner
advertisements and sponsorships. Advertising contracts are primarily sold as:
(1) a "run of site" contract under which a customer is guaranteed a number of
impressions; (2) a "key word" contract in which a customer purchases the right
to advertise in connection with specified word searches; or (3) a "targeted"
contract where the customer purchases a specified number of impressions in one
of the targeted categories or on a specified page or service.

     Electronic Commerce, Licensing and Other Revenues   Electronic commerce,
licensing and other revenues were $11.5 million and $28.6 million for the three
and nine months ending April 30, 1999, representing 33% and 32% of total
revenues, as compared to electronic commerce, licensing and other revenues of
$3.4 million and $9.4 million for the three and nine months ended April 30,
1998, which represented 23% and 25% of total revenues. The increase in
electronic commerce, licensing and other revenues is attributable primarily to
the addition of several new partners including, among others, WebMD, Audio Book
Club, AutoConnect, AT&T and Preview Travel.


                                      10

     Electronic commerce revenues are derived principally from "slotting fees"
paid for selective positioning and promotion within the Company's suite of
products as well as from royalties from the sale of goods and services from the
Company's websites. The Company's license and product revenues are derived
principally from product licensing fees and fees from maintenance and support of
its products. Electronic commerce, license and product revenues are generally
recognized upon delivery provided that no significant Company obligations remain
and collection of the receivable is probable. In cases where there are
significant remaining obligations, the Company defers such revenue until those
obligations are satisfied. Fees from maintenance and support of the Company's
products including revenues bundled with the initial licensing fees are deferred
and recognized ratably over the service period.

     Cost of Revenues   Cost of revenues were $7.1 million and $18.9 million for
the three and nine months ending April 30, 1999, representing 20% and 21% of
total revenues, as compared to cost of revenues of $4.7 million and $9.2 million
for the three and nine months ended April 30, 1998, which represented 31% and
25% of total revenues. Cost of revenues consist primarily of expenses associated
with the ongoing maintenance and support of the Company's products and services,
including compensation, consulting fees, equipment costs, networking and other
related indirect costs.

Operating expenses

     Research and Development   Research and development expenses were $6.5
million and $17.8 million for the three and nine months ending April 30, 1999,
representing 19% and 20% of total revenues, as compared to research and
development expenses of $2.7 million and $5.9 million for the three and nine
months ended April 30, 1998, which represented 18% and 16% of total revenues.
Research and development expenses consist primarily of equipment and salary
costs. The overall increase in research and development expenses was primarily
due to increased engineering staffing to continue to develop and enhance the
Company's expanded product offerings.

     With the exception of acquired technology, all research and development
costs have been expensed as incurred. The Company believes that significant
investments in research and development are required to remain competitive. As a
consequence, the Company expects to continue to commit substantial resources to
research and development in the future.

     Sales and Marketing   Sales and marketing expenses were $20.6 million and
$54.8 million for the three and nine months ending April 30, 1999, representing
59% and 61% of total revenues, as compared to sales and marketing expenses of
$10.2 million and $23.0 million for the three and nine months ended April 30,
1998, which represented 67% and 62% of total revenues. Sales and marketing
expenses consist primarily of compensation, advertising, public relations, trade
shows, travel and costs of marketing literature. The spending increases were due
to the addition of sales and marketing personnel, increased commissions
associated with higher sales, and expenses pertaining to the Company's expanded
advertising, marketing and public relations campaign. Sales and marketing
expense also includes the cost of the Company's "Premier Provider" Agreements,
as further described below. The Company expects continued increases in sales and
marketing expenses in future periods.

     During the nine months ended April 30, 1999, the Company paid approximately
$19 million under Premier Provider Agreements to provide search and navigation
services between June 1998 and September 1999. The Company recognizes the cost
of the Premier Provider Agreements over the one year terms, with the cost
included in sales and marketing expense.

     General and Administrative   General and administrative expenses were $3.3
million and $8.9 million for the three and nine months ending April 30, 1999,
representing 10% and 10% of total revenues, as compared to general and
administrative expenses of $1.5 million and $3.4 million for the three and nine
months ended April 30, 1998, which represented 10% and 9% of total revenues.
General and administrative expenses consist primarily of compensation, rent
expenses and fees for professional services. The increases in spending were
primarily due to the expansion of the Company's corporate infrastructure,
including the addition of finance and administrative personnel, installation of
information systems and increased costs for professional services.

     Amortization of Intangible Assets   Amortization of intangible assets was
$12.3 million and $35.7 million for the three and nine months ended April 30,
1999 versus $2.3 million and $2.5 million for the three and nine months ended
April 30, 1998. The increase is attributable to increased amortization related
to developed technology and goodwill and other intangible assets recorded upon
the acquisitions of WhoWhere?, Tripod, WiseWire and GuestWorld.

     Interest Income, net   Interest income was $1.4 million and $4.9 million
for the three and nine months ending April 30, 1999, as compared to interest
income of $524,000 and $1.6 million for the three and nine months ended April
30, 1998. Interest income is generated from investment of the Company's cash
equivalents. The increase in interest income reflects the investment of the net
proceeds of the Company's secondary stock offering in June 1998. Interest
expense was not significant for any of the periods presented.

     Gain on sale of Investments   In August 1998, pursuant to an Agreement and
Plan of Merger, Amazon.com acquired all of the outstanding capital stock of
PlanetAll for approximately 2.4 million shares of Amazon.com common stock valued
at approximately $87 million. Of the total 2.4 million shares issued by
Amazon.com, the Company received 322,128 shares valued at approximately $12.8
million at the time of acquisition in exchange for its shares of PlanetAll,
resulting in a gain of $10.1 million in the quarter ended October 31, 1998. The
Company has 32,211 shares of Amazon.com remaining at April 30, 1999, which are
subject to escrow restrictions that expire in August 1999.

Factors which may affect future operations

         There are a number of business factors which singularly or combined may
affect the Company's future operating results. These factors include, without
limitation, the level of usage of the Internet and traffic to the Company's
Internet site, continued acceptance of the Company's products, demand for
Internet advertising, seasonal trends in advertising sales, the advertising
budgeting cycles of individual advertisers, capital expenditures and other costs
relating to the expansion of operations, the introduction of new products or
services by the Company or its competitors, the mix of the services sold and the
channels through which those services are sold, pricing changes, general
economic conditions and specific economic conditions in the Internet industry
and other risks detailed in the Company's filings with the Securities and
Exchange Commission.

         In addition, other risks and uncertainties that could impact the
proposed business combinations with Wired Ventures, Inc. include, but are not
limited to, the satisfaction of conditions to consummation of the proposed
transaction, the risk that the anticipated strategic and financial benefits of
the proposed transaction may not be achieved, or may not be achieved within the
time frame envisioned, general economic conditions and specific economic
conditions in the Internet and media industries, including the volatility of
capital markets in respect to the securities of Internet and media companies,
and other risks detailed in the filings of the Company with the Securities and
Exchange Commission.

Liquidity and Capital Resources

     At April 30, 1999, the Company had cash and cash equivalents of
approximately $132.4 million. The Company regularly invests excess funds in
short-term money market funds, government securities and commercial paper.

     The Company used cash from operations of approximately $34.8 million during
the nine months ended April 30, 1999, due primarily to increases in license fees
receivable and prepaid expenses, and decreases in accrued expenses. The increase
in prepaid expenses reflects approximately $19 million in payments made under
the Company's Premier Provider Agreements, which provide search and navigation
services through September 1999.

     The Company generated cash from investing activities of approximately $8.3
million during the nine months ended April 30, 1999, due primarily to cash
proceeds from the sale of Amazon.com stock in October 1999, net of approximately
$3.5 million of investments, primarily the Company's $2 million investment in
Valent Software Corporation in December 1998.

     The Company generated cash from financing activities of approximately $5.1
million during the nine months ended April 30, 1999, due primarily to proceeds
of $7.3 million received by the Company from the exercise of employee stock
options, net of $3.1 million of payments on notes payable assumed upon the
acquisition of WhoWhere?.


                                      12
<PAGE>

     As of April 30, 1999, the Company had deferred revenues of $148.0 million
representing primarily license fees to be earned in the future on noncancelable
license agreements.

     On June 8, the Company announced the relocation of all Lycos Pittsburgh
functions and responsibilities to corporate headquarters in Waltham. This
relocation is expected to be completed in the second quarter of 2000. The cost
of this relocation will be recorded in the fourth quarter of 1999.

     The Company currently believes that available funds and cash flows expected
to be generated by operations, if any, will be sufficient to fund its working
capital and capital expenditures requirements for at least the next twelve
months. Thereafter, the Company may need to raise additional funds. The Company
may need to raise additional funds sooner in order to fund more rapid expansion,
to develop new or enhanced products and services, to respond to competitive
pressures or to acquire complementary businesses or technologies. If additional
funds are raised through the issuance of equity securities, the percentage
ownership of the stockholders of the Company will be reduced, stockholders may
experience additional dilution, and such equity securities may have rights,
preferences or privileges senior to those of the Company's Common Stock. There
can be no assurance that additional financing will be available when needed on
terms favorable to the Company or at all. If adequate funds are not available or
are not available on acceptable terms, the Company may be unable to develop or
enhance products or services, take advantage of future opportunities or respond
to competitive pressures, which could have a material adverse effect on the
Company's business, results of operations or financial condition.

Proposed Business Combinations

     On October 5, 1998, the Company entered into a definitive merger agreement
to acquire Wired Ventures Inc. ("Wired") in a stock-for-stock transaction. The
transaction will be accounted for under the purchase method of accounting, and
accordingly, the purchase price will be allocated to assets acquired and
liabilities assumed based on their respective fair values. Intangible assets
will be amortized over a period of five years. The merger is subject to several
conditions, including Wired shareholder approval and customary regulatory
approvals. The Company has filed a Registration Statement on Form S-4, which is
pending the approval of the Securities and Exchange Commission, with respect to
the registration of the shares of Lycos Common Stock to be issued in the merger.
Additional information with respect to this proposed transaction is available on
Form S-4 filed with the Securities and Exchange Commission on November 25, 1998,
and amended on February 2, 1999, April 16,1999 and May 20, 1999.

     On February 9, 1999, the Company announced the proposed formation of
USA/Lycos Interactive Networks, Inc.("USA/Lycos"), a three way merger between
Lycos, Ticketmaster Online-CitySearch, Inc. ("TMCS") and certain USA Networks,
Inc. ("USAi") properties - Home Shopping Network, Ticketmaster and First
Auction. On May 12, 1999, Lycos, Inc. and USA Networks, Inc. jointly announced a
mutual consent to terminate the merger agreement. The option agreement between
USA Networks and Lycos that was part of the merger was also terminated. The
termination agreement requires Lycos to pay USAi and TMCS an aggregate of $35
million under certain circumstances if prior to July 15, 1999 Lycos enters into
an agreement with respect to, or becomes subject to, certain acquisition
proposals. In addition, subject to certain exceptions, USAi and TMCS each has
agreed that until July 15, 1999, it will not acquire Lycos stock or make any
proposals to acquire Lycos. Expenses incurred in connection with this
transaction will be recorded in the fourth quarter of 1999.

Year 2000 Compliance

     Many currently installed computer systems and software products are coded
to accept only two-digit entries in the date code field and cannot distinguish
21st century dates from 20th century dates. These date code fields will need to
distinguish 21st century dates from 20th century dates and, as a result, many
companies' software and computer systems may need to be upgraded or replaced in
order to comply with such "Year 2000" requirements.

     State of Readiness   The Company has evaluated the year 2000 readiness of
the hardware and software products sold by the Company ("Products"), the
information technology systems used in its operations ("IT Systems"), and its
non-IT Systems, such as building security, voice mail and other systems. The
Company's evaluation covered the following phases: (i) identification of all
Products, IT Systems, and non-IT Systems; (ii) assessment of repair or
replacement requirements; (iii) repair or replacement; (iv) testing; (v)
implementation; and (vi) creation of contingency plans in the event of year 2000
failures. The evaluation was completed in 1998. Based on this evaluation, the
Company believes it is year 2000 compliant.

                                      13
<PAGE>

     However, the assessment of whether a complete system or device in which a
product is embedded will operate correctly for an end-user depends in large part
on the year 2000 compliance of the product or system's other components, many of
which are supplied by parties other than the Company. The supplier of the
Company's current financial and accounting software has informed the Company
that such software is year 2000 compliant. Further, the Company relies, both
domestically and internationally, upon various vendors, governmental agencies,
utility companies, telecommunications service companies, delivery service
companies and other service providers who are outside of the Company's control.
There is no assurance that such parties will not suffer a year 2000 business
disruption, which could have a material adverse effect on the Company's
financial condition and results of operations.

     Costs   To date, the Company has not incurred any material expenditures in
connection with identifying or evaluating year 2000 compliance issues. Most of
its expenses have related to the opportunity cost of time spent by employees of
the Company evaluating its software, the current versions of its products, and
year 2000 compliance matters generally.

     Contingency Plan   The Company has not developed a year 2000-specific
contingency plan. If year 2000 compliance issues are discovered, the Company
then will evaluate the need for contingency plans relating to such issues.

                                     PART II

ITEM 1.   Legal Proceedings

               On November 5, 1998, Labrador Software, Inc. filed a lawsuit in
          the United States District Court for the District of Massachusetts
          against Lycos alleging Lycos violated several of Labrador's rights
          under 15 U.S.C. 1125, and Massachusetts statutory and common law. More
          specifically, Labrador alleges that Lycos' current advertising
          campaign featuring a black labrador retriever retrieving information
          on the Internet constitutes: (1) both unfair competition and trademark
          infringement under both federal and common law; (2) injury to
          Labrador's business reputation and trademark dilution under
          Massachusetts statutory and common law; and (3) unfair and deceptive
          trade practices under Massachusetts statutory law. Labrador requested
          that the court issue a temporary restraining order restraining Lycos
          from selling or advertising the Lycos products and services under the
          current advertising campaign, which request the court denied. Labrador
          has appealed the order denying the motion. Lycos is vigorously
          defending against the lawsuit and does not believe the outcome would
          have a material adverse effect on its business, financial condition,
          results of operations or cash flows.

               In January 1999, CIVIX-DDI brought a suit for patent infringement
          in the United States District Court for the District of Colorado (Case
          No. 99-B-172) against Lycos, Inc.; Microsoft Corporation; The Denver
          Post Corporation; Rand-McNally & Company, Inc.; Delorme Publishing
          Company, Inc.; InfoUSA, Inc.; Geosystems Global Corporation; Vicinity
          Corporation; Etak, Inc.; America Online, Inc.; Yahoo!, Inc.;
          Ticketmaster Online-CitySearch, Inc.; Zip2 Corporation; Infoseek
          Corporation; Alpine Electronics of America, Inc.; Magellan
          Corporation; Garmin International, Inc.; Excite, Inc.; Infospace.com,
          Inc.; and BellSouth Corporation. CIVIX-DDI asserts that Lycos, among
          others, infringes two patents that generally relate to electronic
          mapping systems. CIVIX-DDI is seeking unspecified damages, including
          attorneys' fees, as well as an injunction. Lycos' answer to the
          complaint is due on March 29, 1999. Discovery has not yet begun in
          this litigation, and as such, it is too early to determine any
          possible effect on the Company's business, financial condition,
          results of operations or cash flows.

               Eight purported class action lawsuits were filed in the Court of
          Chancery for the State of Delaware in and for New Castle County, by
          shareholders of the Company allegedly on behalf of all common

          request that the Court declare them to be proper class actions, enjoin
          the announced transaction, rescind the announced transaction if it is
          consummated prior to a final judgment or award rescissionary damages
          to the purported class, direct the Company to make an accounting to
          plaintiffs and the purported class for all damages and for all profits
          or special benefits obtained by the defendants, and award to
          plaintiffs all costs and fees, including attorneys' fees. The Company
          believes that the allegations in the complaints are without merit and
          intends to contest them vigorously.
