stock, without par value, of Acquisition shall be converted into one share of

shares of Parent Common Stock received as Merger Consideration (the "PARENT
SHARES") for investment solely for its own account and not with a view to, or
for resale in connection with, any distribution thereof and is aware that Parent
is relying upon the bona fide nature of Microsoft's investment intent as
expressed herein.  Microsoft further understands that the Parent Shares to be
acquired have not been registered under the Securities Act (as defined below)
and have not been qualified under applicable state securities laws and that any
subsequent disposition thereof must be registered under the Securities Act and
qualified under applicable state securities laws or be exempt from such
registration and qualification.  Microsoft confirms that in making the decision
to acquire the Parent Shares, Microsoft and its advisors have been given the
opportunity to examine all documents and to ask questions of, and to receive
answers from, Parent's management and advisors concerning the terms and
conditions of the transactions contemplated by this Agreement and other matters
set forth in any schedule or attachment hereto.  Such examination shall not
render any representation or warranty ineffective except to the extent that
Microsoft has actual knowledge (without any duty of inquiry) of any breach in
the representations or warranties of Parent made herein.

                                ARTICLE IV.
           REPRESENTATIONS AND WARRANTIES OF PARENT AND ACQUISITION

              As an inducement to Microsoft and the Company to enter into
this Agreement and to consummate the transactions contemplated herein, Parent
and Acquisition hereby represent and warrant to Microsoft and the Company
that:

              4.01   ORGANIZATION AND EXISTENCE.  Each of Parent and
Acquisition is a corporation duly incorporated, validly existing and in good
standing under the laws of the State of Delaware and has all corporate power
and authority to enter into this Agreement and the Ancillary Agreements and
consummate the transactions contemplated hereby and thereby.  Each of Parent
and Acquisition is duly qualified to do business as a foreign corporation in
each jurisdiction where the character of the property owned or leased by it
or the nature of its activities makes such qualification necessary to carry
on its business as now conducted, except for those jurisdictions where in the
aggregate the failure to be so qualified is not, and is not reasonably
expected to become, material.

              4.02   CORPORATE AUTHORIZATION.  The execution, delivery and
performance by each of Parent and Acquisition of this Agreement and the
Ancillary Agreements and the consummation by Parent and Acquisition of the
transactions contemplated hereby are within the corporate powers of Parent
and Acquisition and have been duly authorized by all necessary corporate
action on the part of Parent and Acquisition.  This Agreement and the
Ancillary Agreements constitute a legal, valid and binding agreement of
Parent and Acquisition, each enforceable in accordance with its terms, except
(a) as rights to indemnity hereunder may be limited by federal or state
securities laws or the public policies embodied therein, (b) as such
enforceability may be limited by bankruptcy, insolvency, moratorium,
reorganization or similar laws affecting the enforcement of creditors' rights
generally and (c) as the remedy of specific performance and other forms of
injunctive relief may be subject to equitable defenses and to the discretion
of the court before which any proceeding therefor may be brought.

              4.03   GOVERNMENTAL AUTHORIZATION.  The execution, delivery and
performance of this Agreement and the Ancillary Agreements by Parent and
Acquisition  require no action by, consent or approval of, or filing with,
any Governmental Authority other than any actions, consents, approvals or
filings otherwise expressly referred to in this Agreement.

              4.04   NON-CONTRAVENTION.  The execution, delivery and
performance by the Parent and Acquisition of this Agreement and the Ancillary
Agreements does not and will not (a) contravene or conflict with the Charters
or Bylaws of Parent and Acquisition, (b) contravene or constitute a default
under any material agreement to which Parent or Acquisition  is a party or
(c) assuming compliance with the matters referred to in SECTION 4.03,
contravene or conflict with or constitute a violation of any provision of any
Applicable Law binding upon or applicable to Parent or Acquisition.

              4.05   LITIGATION.  There is no Proceeding pending against, or
to the best knowledge of Parent and Acquisition, threatened against or
affecting, Parent or Acquisition

                                      20

<PAGE>

before any court or arbitrator or any governmental body, agency or official
that challenges or seeks to prevent, enjoin, alter or materially delay the
transactions contemplated by this Agreement.

              4.06   SEC DOCUMENTS.  Since December 2, 1998, Parent has made
all filings required by the Securities Act of 1933 (the "SECURITIES ACT") and
the Securities Exchange Act of 1934 (the "EXCHANGE ACT"), including for each
act all amendments, rules and regulations (the "PARENT SEC DOCUMENTS").
Except to the extent that information contained in any SEC Report has been
revised or superseded by a later filing, none of the Parent SEC Documents
contains any untrue statement of a material fact or omits to state any
material fact required to be stated wherein or necessary in order to make the
statements therein, in light of the circumstances under which they were made
not misleading.  Since January 1, 1998, as of their respective dates, all
Parent SEC Documents filed under the Securities Act and the Exchange Act
complied in all material respects with the published rules and regulations of
the Securities and Exchange Commission ("SEC") with respect thereto.

              4.07   CAPITALIZATION.  As of the Closing Date, the authorized
capital stock of Acquisition will consist of 25,000 shares of common stock,
without par value, of which 1,000 shares are outstanding, all of which are
owned by Parent.

              4.08   FINANCIAL STATEMENTS.  The financial statements of
Parent (including, in each case, any notes and schedules thereto) included in
the Parent SEC Documents (a) were prepared from the books and records of
Parent and its Subsidiaries, (b) comply as to form in all material respects
with all applicable accounting requirements and the rules and regulations of
the SEC with respect thereto, (c) are in conformity with applicable
accounting principles applied on a consistent basis and (d) fairly present
the consolidated financial position of Parent at the dates thereof and of its
operations and cash flows for the periods then ended (except in the case of
unaudited statements, as permitted by the rules and regulations of the SEC).
There has been no change in Parent accounting policies except as described in
the notes to the financial statements included in Parent SEC Documents.
Parent has no material liabilities or obligations other than (i) those set
forth in such financial statements and (ii) those not required to be set
forth in such financial statements under generally accepted accounting
principles.

              4.09   ACQUISITION'S OPERATIONS.  Acquisition was formed solely
for the purpose of engaging in the transactions contemplated hereby and has
not (a) engaged in any business activities, (b) conducted any operations
other than in connection with the transactions contemplated hereby or (c)
incurred any liabilities other than in connection with the transactions
contemplated hereby.

              4.10   TAX REPRESENTATIONS.  The representations of Parent and
Acquisition to be provided in the Tax Representation Letter in substantially
the form set forth in EXHIBIT B hereto (the "PARENT TAX REPRESENTATION
LETTER") shall have the same force and effect as if such representations of
Acquisition and Parent were set forth in this Section of the Agreement.

                            COVENANTS OF MICROSOFT

              Microsoft hereby covenants and agrees with Parent and
Acquisition as follows:

              5.01   CONDUCT OF THE BUSINESS.  From the date hereof until the
Closing Date, Microsoft will cause the Company to conduct the Business in the
ordinary course and use its commercially reasonable efforts, without paying
or increasing the compensation, payments, remuneration or fees payable to any
Person other than in the ordinary course of business, to preserve intact the
business organizations and relationships and goodwill with third parties
PROVIDED, HOWEVER, that with respect to Microsoft's employees and contingent
staff, Microsoft shall have no obligation other than as set forth in the
Transition Services Agreement (as defined below).  Without limiting the
generality of the foregoing, from the date hereof until the Closing Date:

                     (a)    without Parent's prior consent (which consent shall
not be unreasonably withheld), Microsoft will not allow the Company to and will
not agree to allow the Company to:

                     (i)    purchase or otherwise acquire assets from any other
       Person, or sell or transfer any assets of the Business, other than in the
       ordinary course of business;

                     (ii)   incur any Liability, except Liabilities (A) incurred
       in the ordinary course of business where the aggregate dollar amount of
       all such Liabilities incurred by the Business does not exceed One Hundred
       Thousand Dollars ($100,000), (B) incurred pursuant to existing
       obligations of the Company or Microsoft in connection with the Business
       that are disclosed in the Schedules hereto or (C) expressly contemplated
       by the terms of this Agreement;

                     (iii)  amend or modify in any material respect or terminate
       any Material Contract or any other Contract entered into by the Company
       or Microsoft in connection with the Business after the date hereof which,
       if in existence on the date hereof, would be considered a Material
       Contract (each, a "SUBSEQUENT MATERIAL CONTRACT"); or

                     (iv)   make or commit to make any capital expenditure, or
       group of related capital expenditures, in excess of One Hundred Thousand
       Dollars ($100,000) for the Business, other than (y) capital expenditures
       set forth on SCHEDULE 5.01(a)(iv) and (z) capital expenditures expressly
       required under any Material Contract.

                     (b)    In connection with the Business, Microsoft shall
cause the Company to:

                     (i)    (A) maintain its assets in the ordinary course of
       business in reasonably serviceable operating order and condition,
       reasonable wear and tear, damage by fire and other casualty excepted,
       (B) promptly repair, restore or replace any material assets in the
       ordinary course of business and (C) upon any damage, destruction or loss
       to

                                      22

<PAGE>

       any of such assets, apply any and all insurance proceeds received with
       respect thereto to the prompt repair, replacement and restoration thereof
       to the condition of such assets before such event to the extent
       reasonably practicable;

                     (ii)   comply with all material Applicable Laws;

                     (iii)  not allow any liens for Taxes to be placed on any of
       the assets of the Company, except for liens arising from Taxes which are
       due but not yet payable;

                     (iv)   use its commercially reasonable efforts to obtain,
       prior to the Closing Date, all Required Consents;

                     (v)    take all actions within its reasonable control to be
       in compliance with, and to maintain the effectiveness of, all material
       Permits;

                     (vi)   promptly notify Parent in writing if the Company or
       Microsoft has knowledge of any action, event, condition or circumstance,
       or group of actions, events, conditions or circumstances that results in,
       or could reasonably be expected to result in, a Material Adverse Effect,
       other than changes in general economic conditions;

                     (vii)  promptly notify Parent in writing of the
       commencement of any Proceeding by or against the Business, or of becoming
       aware of any material claim, action, suit, inquiry, proceeding, notice of
       violation, subpoena, government audit or disallowance that could
       reasonably be expected to result in a Proceeding; and

                     (viii) pay accounts payable and pursue collection of its
       accounts receivable in the ordinary course of business.

              5.02   AUDITED FINANCIAL STATEMENTS.

                     (a)    In order to enable Parent to comply with its
obligation to file with the SEC financial statements with a Current Report on
Form 8-K or any other document required by the SEC, Microsoft and Company agree
to, as soon as practical upon the execution of this Agreement, prepare and
complete such financial statements for the Business (the "FINANCIAL STATEMENTS")
and to have Deloitte & Touche LLP audit said Financial Statements (as audited,
the "AUDITED FINANCIAL STATEMENTS").  Within two Business Days of the completion
of the audit, and, in any event, within sixty (60) days after the Closing Date,
the Company shall deliver such audited Financial Statements to Parent.  In
addition, Parent shall have the right to review and copy, promptly upon request,
the workpapers of Microsoft, the Company and Deloitte & Touche LLP utilized in
the preparation of the Audited Financial Statements for purposes of verifying
the accuracy thereof.

                     (b)    Microsoft and Company covenant and agree that the
Audited Financial Statements (i) will be prepared based on the books and records
of the Business in accordance with GAAP and present fairly the financial
condition, results of operations and statements of cash flow of the Business as
of the dates indicated or the periods indicated and

                                      23
<PAGE>

(ii) will contain and reflect all necessary adjustments, accruals, provisions
and allowances for a fair presentation of the financial condition of the
Business and the results of operations of the Business for the periods
covered by such financial statement.

                     (c)    Parent and Microsoft each agree to pay fifty percent
(50%) of the fees and costs of Deloitte & Touche LLP in preparing the Audited
Financial Statements and Microsoft and the Company shall bear their own costs in
preparing the Financial Statements; PROVIDED, HOWEVER, that the total amount to
be paid by Parent pursuant to this SECTION 5.02(C) will not exceed Seventy Five
Thousand Dollars ($75,000).

                     (d)    Parent, Microsoft and Company agree to cooperate in
an effort to (i) complete the Audited Financial Statements as soon as
practicable upon the execution of this Agreement and (ii) minimize the burden
imposed upon Microsoft and Company under SECTION 5.02 to provide the Audited
Financial Statements to Parent.  Parent will use its best commercially
reasonable efforts to obtain permission from the SEC to file only audited
statements of assets and liabilities acquired and statements of revenues and
direct expenses in lieu of the full financial statements required by Regulation
S-X, and will include an explanation of the impracticality of providing such
full financial statements in any filing on a Current Report on Form 8-K.

              5.03   SIDEWALK CONTENT AGREEMENTS.  Promptly following the date
hereof, Microsoft agrees to provide to Parent copies of each and every agreement
and arrangement involving the supply by third parties to Microsoft of Sidewalk
Content, including without limitation all "work made for hire" agreements with
independent contractors that supply Sidewalk Content used in a local site and,
to the extent available, make commercially reasonable efforts to provide the
name of the contact person and phone number of the individual within the
organization of the other contracting party that is responsible for
administering such agreement or arrangement.  Microsoft will use commercially
reasonable efforts to provide all such information sufficiently in advance of
the Closing Date to afford an adequate opportunity for Parent to review such
information, contact the other contracting parties and, if desired by Parent,
negotiate new arrangements for the provision of additional content with such
parties, and Microsoft otherwise will cooperate with Parent to ensure, to the
extent practicable, a smooth and efficient transfer to Parent of the Sidewalk
Content together with the Business.

              5.04   RELEASE OF MORAL RIGHTS.  Microsoft irrevocably waives and
relinquishes, and agrees never to assert or bring, any claim, action or
proceeding in which Microsoft asserts any "moral rights" or their equivalent
arising under the law of any country anywhere in the world that Microsoft may
possess with respect to any Sidewalk Content owned by Microsoft or the Company.

              5.05   CERTAIN PROCEEDINGS.

                     (a)    With respect to the oppositions to Microsoft's
applications for registration in Argentina and Brazil described in SCHEDULE
3.13(b)(2), Microsoft agrees that if such oppositions at any time result in
claims by Universal Studios or any other third party against the Company or
Parent, Microsoft will indemnify and hold Parent and the Company harmless from
and against any and all Damages incurred or to be incurred arising from or in
connection

                                      24
<PAGE>

with such claims and will defend against such third party claims at
Microsoft's sole cost and expense.

                     (b)    With respect to the two patent infringement
lawsuits described on SCHEDULE 3.13(E)(3), Microsoft agrees to indemnify and
hold Parent and the Company harmless from and against any and all Damages
incurred or to be incurred arising from or in connection with such lawsuits
and to continue to defend such lawsuits at Microsoft's sole cost and expense.

                     (c)    The obligations of Microsoft set forth in this
SECTION 5.05 shall not be subject to the limitations of SECTION 8.03.

                                 ARTICLE VI.
                          COVENANTS OF ALL PARTIES

              The parties hereto hereby covenant and agree as follows:

              6.01   FURTHER ASSURANCES.  The parties hereto shall execute
and deliver such other documents, certificates, agreements and other writings
and shall take such other actions as may be reasonably necessary or desirable
(including, without limitation, obtaining the Required Consents and making
necessary filings with all Governmental Authorities) in order to consummate
or implement expeditiously the transactions contemplated by this Agreement.
Each of the parties hereto shall comply with the notification and reporting
requirements of the HSR Act and use its reasonable best efforts to obtain
early termination of the waiting period under the HSR Act.  Notwithstanding
the foregoing, no party hereto shall have any obligation to expend any funds
or to incur any other obligation in connection with the consummation of the
transactions contemplated hereby (including, by way of illustration only, any
payment in connection with obtaining the Required Consents) other than normal
out-of-pocket expenses (such as fees and expenses of counsel and accountants)
reasonably necessary to consummate such transactions.

              6.02   CONFIDENTIALITY; PUBLIC ANNOUNCEMENTS.  The parties
hereto shall use their best efforts to keep this Agreement and the execution
and terms hereof confidential, and shall consult with each other before
issuing any press release or making any public statement with respect to this
Agreement or the transactions contemplated hereby.  The parties may, however,
disclose such matters to its directors, officers, executive employees and
professional advisors and those of prospective financing sources to such
extent as may be reasonable for the negotiation, execution and consummation
of this Agreement. Each party shall keep confidential all information
concerning the other obtained pursuant to this Agreement and shall not use
such information except in connection with the transactions set forth herein.
If for any reason such transactions shall not be consummated, each party
will return all such information (including all copies thereof) regarding the
other, to the other party.  The foregoing obligations of confidentiality in
this SECTION 6.02 do not pertain to the disclosure of information which is
available publicly, is required to be disclosed by any court or any party
discloses, upon advice of counsel, in order to comply with Applicable Law.
The parties hereto recognize and agree that in the event of a breach by a
party of this section, money damages would not be an adequate remedy to the
injured party for such breach and, even if money damages were adequate, it
would

                                      25
<PAGE>

be impossible to ascertain or measure with any degree of accuracy the damages
sustained by such injured party therefrom.  Accordingly, if there should be a
breach or threatened breach by a party of the provisions of this section, the
injured party shall be entitled to an injunction restraining the breaching
party from any breach without showing or proving actual damage sustained by
the injured party.  Nothing in the preceding sentence shall limit or
otherwise affect any remedies that a party may otherwise have under
Applicable Law.  The parties agree to jointly prepare and to distribute
(singly or jointly) a press release disclosing the execution and delivery of
this Agreement and the substance of the transactions contemplated hereby.

              6.03   DISTRIBUTION AGREEMENT.  On or before the Closing Date,
Parent and Microsoft will enter into that certain MSN/CitySearch Distribution
and Cross Promotion Agreement in the form attached hereto as EXHIBIT C (the
"DISTRIBUTION AGREEMENT").

              6.04   TRANSITION SERVICES AGREEMENT.  Concurrently herewith,
Parent and Microsoft will enter into that certain Transition Services
Agreement of even date herewith (the "TRANSITION SERVICES AGREEMENT"),
pursuant to which Microsoft will provide transitional services to Parent on
the terms provided therein.

              6.05   LICENSE AGREEMENT.  On or before the Closing Date,
Parent and Microsoft will enter into that certain License Agreement in the
form attached hereto as EXHIBIT D (the "LICENSE AGREEMENT).

              6.06   TAX MATTERS.

                     (a)    Parent, Microsoft and Acquisition will report the
Merger on their U.S. federal income tax returns in a manner consistent with
the Merger constituting a reorganization within the meaning of Code Section
368(a) and will comply with all reporting obligations of such a
reorganization set forth in the Code and the Treasury Regulations promulgated
thereunder, unless any of the parties to this Agreement are required,
pursuant to a "determination" within the meaning of Code Section 1313(a), to
treat the Merger in a different manner.

                     (b)    Microsoft shall arrange to have all Tax Returns
of the Company with respect to periods ending on or prior to the Closing Date
prepared and filed, and signed by a current officer of the Company.
Microsoft, Parent and the Company shall cooperate in good faith in the
preparation of such Tax Returns and in any tax audit or examination of the
Company, and shall retain and make available to any other party any
documentation which is necessary or required for the preparation of such Tax
Returns or in connection with any such audit or examination.

                     (c)    Following the Closing, from time to time as the
Company may reasonably request, Microsoft will provide to the Company
information regarding the tax basis and other tax attributes of the assets of
the Company sufficient to enable Parent and the Company to comply with their
Tax reporting obligations.  Thereafter, Microsoft shall inform Parent on a
timely basis of any adjustments to the tax basis of the assets or other tax
attributes of the Company as a result of any audit, examination or other Tax
proceedings.

                                      26
<PAGE>

              6.07   LOCK-UP.  Microsoft agrees that it will not offer to
sell, contract to sell, or otherwise sell, dispose of, loan, pledge or grant
any rights with respect to (collectively, a "DISPOSITION") any Parent Shares
for a period commencing on the Closing Date and continuing to a date 180 days
after the Closing Date (the "LOCK-UP PERIOD"); PROVIDED, HOWEVER, that
nothing in this SECTION 6.07 will prevent Microsoft from engaging in certain
"hedging transactions" so long as Microsoft uses commercially reasonable
efforts to affect such hedging transactions in a manner that will minimize
any adverse effects on the trading price of Parent Common Stock on the Nasdaq
National Market.  Microsoft also consents to the entry of stop transfer
instructions by Parent's transfer agent and registrar prohibiting the
transfer of Parent Shares by Microsoft except in compliance with the
foregoing restrictions; PROVIDED, HOWEVER, that, upon the reasonable request
of Microsoft, the Parent Shares shall be released from such stop transfer
instructions and issued without legends to permit Microsoft to lend such
Parent Shares to counterparties in connection with hedging transactions, but
only insofar as any such transaction is conducted in accordance with the
covenants set forth in the immediately preceding sentence.

              6.08   CASH ADJUSTMENT TO MERGER CONSIDERATION.

                     (a)    Microsoft and Parent understand and agree that
Microsoft will be responsible for, and will reimburse Parent for, or pay
directly, any and all operating expenses of the Company incurred during the
period ending on the Closing Date (the "INTERIM PERIOD").  Such operating
expenses shall include, without limitation, (i) salaries, wages and other
employee expenses, (ii) rental payments, (iii) utility payments, (iv) Taxes
and (v) Liabilities or commitments incurred in violation of SECTIONS
5.01(A)(ii) and (iv), in each case whether or not then due and payable and
prorated through the Closing Date (collectively, the "PAYABLES").

                     (b)    Without limiting the generality of the foregoing,
within ten (10) Business Days following the Closing Date (i) to the extent
that the Payables exceed the cash on hand of the Company, net of any
outstanding checks or bank drafts (the "CASH"), Microsoft shall pay to Parent
an amount in cash equal to such excess and (ii) to the extent that the Cash
exceeds the Payables, then Parent shall pay to Microsoft an amount in cash
equal to such excess.

                     (c)    Parent will, from time to time, tender to
Microsoft payments in respect of accounts receivable relating exclusively to
the Interim Period received by the Company after the Closing Date.

                                    ARTICLE VII.
                               CONDITIONS TO CLOSING

              7.01   CONDITIONS TO OBLIGATION OF PARENT AND ACQUISITION.  The
obligations of Parent and Acquisition to consummate the Closing are subject to
the satisfaction of each of the following conditions:

                     (a)    (i) Each of Microsoft and the Company shall have
performed and satisfied each of its obligations hereunder and in the Ancillary
Agreements required to be performed and satisfied by it on or prior to the
Closing Date, (ii) each of the representations and warranties of Microsoft and
the Company contained herein and in the Ancillary Agreements

                                      27
<PAGE>

shall have been true, correct and complete when made and shall be true,
correct and complete at and as of the Closing with the same force and effect
as if made as of the Closing, except for breaches that (x) do not have a
Material Adverse Effect on the benefits of the transaction reasonably
anticipated by this Agreement or (y) result from or arise out of actions
taken or avoided at the direction of Parent which Microsoft or the Company
would not have otherwise taken or avoided and (iii) Parent shall have
received certificates signed by duly authorized executive officers of
Microsoft and the Company to the foregoing effect and to the effect that the
conditions specified within this SECTION 7.01 have been satisfied.

                     (b)    All Required Consents shall have been obtained
without condition, and shall be in full force and effect, except to the
extent that the failure to obtain such consents does not have a Material
Adverse Effect on the benefits of the transaction reasonably anticipated by
this Agreement. All waiting periods under the HSR Act (and any extension
thereof) applicable to the transactions contemplated by this Agreement shall
have expired or terminated.  No Proceedings shall have been instituted or
threatened by any Governmental Authority with respect to any Required
Governmental Approval as to which there is a material risk of a determination
that would terminate the effectiveness of, or otherwise materially and
adversely modify the terms of, any such Required Governmental Approval.  All
conditions and requirements prescribed by Applicable Law or any Required
Consent to be satisfied on or prior to the Closing Date shall have been
satisfied to the extent necessary such that all such Required Consents are,
and will remain, in full force and effect assuming continued compliance with
the terms thereof after the Closing, except to the extent that the failure to
satisfy such conditions and requirements does not have a Material Adverse
Effect on the benefits of the transaction reasonably anticipated by this
Agreement.

                     (c)    The transactions contemplated by this Agreement
and the Ancillary Agreements and the consummation of the Closing shall not
materially violate any Applicable Law.  There shall be no actions or
Proceedings underway or threatened by any Governmental Authority (or
determinations by any Governmental Authority) or by any other Person
challenging or in any manner seeking to materially restrict or prohibit the
transactions contemplated hereby or the consummation of the Closing, or to
impose conditions that would be reasonably likely to have a Material Adverse
Effect; PROVIDED, HOWEVER, that Parent and Acquisition shall be deemed to
automatically waive this condition if Microsoft agrees to indemnify, defend
and hold harmless Parent and Acquisition against any such action.

                     (d)    Microsoft shall have duly executed and delivered
to Parent the Distribution Agreement.

The obligations of Microsoft and the Company to consummate the Closing are
subject to the satisfaction of each of the following conditions unless waived
by Microsoft:

                     (a)    (i) Each of Parent and Acquisition shall have
performed and satisfied each of its obligations hereunder and in the
Ancillary Agreements required to be performed and satisfied by it on or prior
to the Closing Date; (ii) each of the representations and warranties of
Parent and Acquisition contained herein and in the Ancillary Agreements shall
have been true, correct and complete when made and shall be true, correct and
complete at and as of the Closing with the same force and effect as if made
as of the Closing, except for breaches that (x) do not have a Material
Adverse Effect on the benefits of the transaction reasonably anticipated by
this Agreement or (y) result from or arise out of actions taken or avoided at
the direction of Microsoft which Parent or Acquisition would not have
otherwise taken or avoided and (iii) Microsoft shall have received a
certificate signed by duly authorized executive officers of Parent and
Acquisition to the foregoing effect and to the effect that the conditions
specified within this SECTION 7.02 have been satisfied.

                     (b)    All Required Consents shall have been obtained

extent that the failure to obtain such consents does not have a Material
Adverse Effect on the benefits of the transaction reasonably anticipated by

thereof) applicable to the transactions contemplated by this Agreement shall
have expired or terminated.  No Proceedings shall have been instituted or
threatened by any Governmental Authority with respect to any Required
Governmental Approval as to which there is a material risk of a determination
that would terminate the effectiveness of, or otherwise materially and
adversely modify the terms of, any such Required Governmental Approval.  All
conditions and requirements prescribed by Applicable Law or any Required
Consent to be satisfied on or prior to the Closing Date shall have been
satisfied to the extent necessary such that all such Required Consents are,
and will remain, in full force and effect assuming continued compliance with
the terms thereof after the Closing, except to the extent that the failure to
satisfy such conditions and requirements does not have a Material Adverse
Effect on the benefits of the transaction reasonably anticipated by this
Agreement.

                     (c)    The sale and transfer contemplated by this
Agreement and the Ancillary Agreements and the consummation of the Closing

Proceedings underway or threatened by any Governmental Authority (or
determinations by any Governmental Authority) or by any other Person
challenging or seeking to materially restrict, prohibit or condition the
transactions contemplated hereby or the consummation of the Closing.

                     (d)    Parent shall have duly executed and delivered to
Microsoft the Distribution Agreement.

                     (e)    Parent shall have duly executed and delivered to
Microsoft the Transition Services Agreement.

                                  INDEMNIFICATION

              8.01   AGREEMENT TO INDEMNIFY.

                     (a)    Parent and its Affiliates (collectively, the "PARENT
INDEMNITEES") shall each be indemnified and held harmless to the extent set
forth in this ARTICLE VIII by Microsoft in respect of any and all Damages
reasonably and proximately incurred by any Parent Indemnitee:

                            (i) as a result of any inaccuracy or
misrepresentation in or breach of any representation, warranty, covenant or
agreement made by Microsoft or the Company in this Agreement as of the Closing;
and

                            (ii) arising from a claim by a third party that:

                            (A) any of the Sidewalk Content or any other Content
       used or displayed by Microsoft or the Company on or in connection with
       Sidewalk.com at any time prior to the Closing Date, or the Sidewalk Mark
       or any other Mark used or displayed by Microsoft or the Company on or in
       connection with Sidewalk.com at any time prior to the Closing Date, or
       the exercise of any Intellectual Property Rights in connection with the
       conduct of the Business prior to the Closing Date, or

                            (B) any of the Owned Content Copyrights or the
       Sidewalk Mark, or the use, display or exploitation of the Sidewalk Mark
       in the same manner as used by Microsoft as of the Closing Date or of any
       of the Owned Content Copyrights, by any Parent Indemnities in connection
       with the conduct on and after the Closing Date of (1) the Business, (2)
       the business of Parent relating to Parent's Citysearch online business or
       (3) any similar online city guide business launched by any Parent
       Indemnitee (including without limitation any successor to the Business or
       the Citysearch online business),

infringes, violates, misappropriates or otherwise wrongfully exploits any
Intellectual Property Rights of any third party, excluding any such claim to the
extent it is based on, or would not have arisen but for, modifications made
following the Closing Date by any person other than

                                      30
<PAGE>

Microsoft, or otherwise violates any rights of any third party (including by
giving rise to libel or defamation cause of action).

                     (b)    Microsoft shall indemnify Parent and the Company
(i) for all Taxes of Microsoft and the Microsoft affiliated group, and for
all Taxes of the Company for all periods ending on or before the Closing
Date, (ii) for all Excluded Liabilities (as defined in SCHEDULE II) and (iii)
for any Damages resulting from claims by third parties that Microsoft or the
Company breached any obligations to such third party on or before the Closing
Date or as a result of the transactions contemplated hereby (it being
understood that Microsoft shall not be responsible for, and shall not
indemnify Parent for Damages resulting from, the inability to assign certain
contracts relating to the Business to the Company).

                     (c)    The Company and its Affiliates (collectively, the
"COMPANY INDEMNITEES") shall be indemnified and held harmless to the extent
set forth in this ARTICLE VIII by Parent in respect of any and all Damages
reasonably and proximately incurred by any Company Indemnitee as a result of
any inaccuracy or misrepresentation in or breach of any representation,
warranty, covenant or agreement made by the Parent in this Agreement.

                     (d)    Except as set forth in SECTIONS 8.01(a), (b) and
(c) and except to the extent of confidentiality provisions in this Agreement,
no Person shall have any claim or cause of action as a result of any
inaccuracy or misrepresentation in or breach of or failure to perform any
representation, warranty, covenant, agreement or obligation of any
Indemnifying Party referred to in this SECTION 8.01 against any Affiliate,
stockholder, director, officer, employee, consultant or agent of such
Indemnifying Party.  Nothing set forth in this ARTICLE VIII shall be deemed
to prohibit or limit any Parent Indemnitee's or Company Indemnitee's right at
any time before, on or after the Closing Date, to seek injunctive or other
equitable relief for the failure of any Indemnifying Party to perform any
covenant or agreement contained herein.

              8.02   SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.

                     (a)    Except as hereinafter provided in this SECTION
8.02, all representations, warranties, covenants, agreements and obligations
of each Indemnifying Party contained herein and all claims of any Parent
Indemnitee or Company Indemnitee in respect of any breach of any
representation, warranty, covenant, agreement or obligation of any
Indemnifying Party contained in this Agreement, shall survive the Closing and
shall expire on April 30, 2001, except for covenants or obligations which by
their terms shall be performed after the Closing which shall survive the
Closing and not expire unless otherwise provided in this Agreement.
Notwithstanding anything herein to the contrary, indemnification for claims
for which written notice as provided in SECTION 8.05 has been timely given
shall not expire until the final resolution of such claim in accordance with
SECTION 10.11.

                     (b)    Notwithstanding SECTION 8.02(a), each of the
following representations, warranties, covenants, agreements and obligations
of Microsoft as Indemnifying Party shall survive the Closing Date until the
thirty (30) days after the expiration of any applicable statute of
limitations, including extensions thereof:  (i) the inaccuracy or
misrepresentation in or breach of any representation, warranty, covenant or
agreement made by

                                      31
<PAGE>

Microsoft at any time in this Agreement arising out of fraud; (ii) any
inaccuracy or misrepresentation in or breach of any representation or
warranty made in SECTIONS 3.01, 3.02, 3.14 or 3.15 or any breach of any
covenant contained in SECTION 10.03 regardless of whether such inaccuracy or
misrepresentation or breach arises out of fraud, gross negligence or willful
misconduct; (iii) any obligation of Microsoft as Indemnifying Party under
SECTION 8.01(b)(i); and (iv) the breach or failure to perform by Microsoft or
the Company after the Closing Date of any of the covenants, agreements or
obligations of Microsoft contained in this Agreement or in the Exhibits
attached hereto which by their terms shall be performed after the Closing.

                     (c)    Notwithstanding SECTION 8.02(a), each of the
following representations, warranties, covenants, agreements and obligations
of Parent as an Indemnifying Party shall survive the Closing Date until the
expiration of the applicable statute of limitations, including extensions
thereof:  (i) any inaccuracy or misrepresentation in or breach of any
representation, warranty, covenant or agreement made by Parent in this
Agreement arising out of fraud; (ii) any inaccuracy or misrepresentation in
or breach of any representation or warranty made in SECTIONS 4.01 and 4.02,
regardless of whether such inaccuracy or misrepresentation or breach arises
out of fraud, gross negligence or willful misconduct; and (iii) the breach or
failure to perform by Parent after the Closing Date of any of the covenants,
agreements or obligations of Parent contained in this Agreement or in the
Exhibits attached hereto which by their terms shall be performed after the
Closing.

              8.03   LIMITATION.  The Parent Indemnitees shall be entitled to
indemnification pursuant to SECTION 8.01(a) only if the total aggregate
Damages under SECTION 8.01(a) exceeds One Million Five Hundred Thousand
Dollars ($1,500,000).  The aggregate amount which the Parent Indemnitees
shall be entitled to be indemnified for under SECTION 8.01(a) will not exceed
Sixty Million Dollars ($60,000,000).  The sole remedy of the Parent
Indemnities for breaches of this Agreement shall be claims made in accordance
with and subject to the limitations of this ARTICLE VIII.

              8.04   CLAIMS FOR INDEMNIFICATION.  If any Indemnitee shall
believe that such Indemnitee is entitled to indemnification pursuant to this
ARTICLE VIII in respect of any Damages, such Indemnitee shall give the
appropriate Indemnifying Party prompt written notice thereof.  Any such
notice shall set forth in reasonable detail and to the extent then known the
basis for such claim for indemnification.  The failure of such Indemnitee to
give notice of any claim for indemnification promptly, but within the periods
specified by SECTION 8.02(A), (b) or (c), as the case may be, shall not
adversely affect such Indemnitee's right to indemnity hereunder except to the
extent that such failure adversely affects the right of the Indemnifying
Party to assert any reasonable defense to such claim.  Each such claim for
indemnity shall expressly state that the Indemnifying Party shall have only
the twenty (20) Business Day period referred to in the next sentence to
dispute or deny such claim.  The Indemnifying Party shall have twenty (20)
Business Days following its receipt of such notice either (y) to acquiesce in
such claim and its respective responsibilities to indemnify the Indemnitee in
respect thereof in accordance with the terms of this ARTICLE VIII by giving
such Indemnitee written notice of such acquiescence or (z) to object to the
claim by giving such Indemnitee written notice of the objection.  If the
Indemnifying Party does not object thereto within such twenty (20) Business
Day period, such Indemnifying Party

                                      32
<PAGE>

shall be deemed to have acquiesced in such claim and their respective
responsibilities to indemnify the Indemnitee in respect thereof in accordance
with the terms of this ARTICLE VIII.

              8.05   DEFENSE OF CLAIMS.  In connection with any claim which
may give rise to indemnity under this ARTICLE VIII resulting from or arising
out of any claim or Proceeding against an Indemnitee by a Person that is not
a party hereto, the Indemnifying Party may (unless such Indemnitee elects not
to seek indemnity hereunder for such claim), upon written notice sent at any
time to the relevant Indemnitee, assume the defense of any such claim or
Proceeding if the Indemnifying Party with respect to such claim or Proceeding
acknowledges to the Indemnitee the Indemnitee's right to indemnity pursuant
hereto in respect of the entirety of such claim (as such claim may have been
modified through written agreement of the parties or arbitration hereunder)
and provide assurances, reasonably satisfactory to such Indemnitee, that the
Indemnifying Party will be financially able to satisfy such claim in full if
such claim or Proceeding is decided adversely.  If the Indemnifying Party
assumes the defense of any such claim or Proceeding, the Indemnifying Party
shall select counsel reasonably acceptable to such Indemnitee to conduct the
defense of such claim or Proceeding, shall take all steps reasonably
necessary in the defense or settlement thereof and shall at all times
diligently and promptly pursue the resolution thereof.  If the Indemnifying
Party shall have assumed the defense of any claim or Proceeding in accordance
with this SECTION 8.05, the Indemnifying Party shall be authorized to consent
to a settlement of, or the entry of any judgment arising from, any such claim
or Proceeding, without the prior written consent of such Indemnitee;
PROVIDED, HOWEVER, that the Indemnifying Party shall pay or cause to be paid
all amounts arising out of such settlement or judgment either concurrently
with the effectiveness thereof or shall obtain and deliver to such
Indemnitees prior to the execution of such settlement a general release
executed by the Person not a party hereto, which general release shall
release such Indemnitee from any liability in such matter; PROVIDED, FURTHER,
that the Indemnifying Party shall not be authorized to encumber any of the
assets of any Indemnitee or to agree to any restriction that would apply to
any Indemnitee or to its conduct of business; and PROVIDED, FURTHER, that a
condition to any such settlement shall be a complete release of such
Indemnitee and its Affiliates, officers, employees, consultants and agents
with respect to such claim.  Such Indemnitee shall be entitled to participate
in (but not control) the defense of any such action, with its own counsel and
at its own expense.  Each Indemnitee shall, and shall cause each of its
Affiliates, officers, employees, consultants and agents to, cooperate fully
with the Indemnifying Party in the defense of any claim or Proceeding being
defended by the Indemnifying Party pursuant to this SECTION 8.05.  If the
Indemnifying Party does not assume the defense of any claim or Proceeding
resulting therefrom in accordance with the terms of this SECTION 8.05, such
Indemnitee may defend against such claim or Proceeding in such manner as it
may deem appropriate, including settling such claim or Proceeding after
giving notice of the same to the Indemnifying Party, on such terms as such
Indemnitee may deem appropriate.  If the Indemnifying Party seeks to question
the manner in which such Indemnitee defended such claim or Proceeding or the
amount of or nature of any such settlement, the Indemnifying Party shall have
the burden to prove by a preponderance of the evidence that such Indemnitee
did not defend such claim or Proceeding in a reasonably prudent manner.

                                    TERMINATION

              9.01   GROUNDS FOR TERMINATION.  This Agreement may be terminated
at any time prior to the Closing:

                     (a)    by mutual written agreement of all of the parties
hereto;

                     (b)    by either Parent or Microsoft at any time by
written notice if there shall have been (1) any one or more material
inaccuracies or material misrepresentations in or material breaches of the
representations or warranties made by another party hereto contained herein
which have had or, if not cured prior to the Closing Date, could be
reasonably expected to have, a Material Adverse Affect when taken into
account with all other uncured inaccuracies or misrepresentations in or
breaches of such representations or warranties or (2) a failure by another
party hereto to perform and satisfy in any material respect and in a timely
fashion any of its obligations under this Agreement required to be performed
and satisfied on or prior to the Closing Date, or a failure by such party to
perform and satisfy any other obligations under this Agreement if the
aggregate of all such other failures shall be material; PROVIDED, HOWEVER,
that a termination pursuant to this SECTION 9.01(b) shall become effective
(i) fifteen (15) days after notice with respect to a misrepresentation or
breach that is not capable of being cured on or prior to the Closing Date is
given, or (ii) immediately prior to the Closing with respect to a
misrepresentation or breach that is capable of being cured, but is not cured,
on or immediately prior to the Closing Date;

                     (c)    by Parent or Microsoft if any Federal, state or
foreign law or regulation thereunder shall hereafter be enacted or become
applicable that makes the transactions contemplated hereby or the
consummation of the Closing illegal or otherwise prohibited, or if any
judgment, injunction, order or decree enjoining either party hereto from
consummating the transactions contemplated hereby is entered, and such
judgment, injunction, order or decree shall become final and nonappealable;
and

                     (d)    by Parent or Microsoft, if the Closing shall not
have been consummated by November 1, 1999 or, only if a Governmental
Authority has made a second request for information under the HSR Act,
January 1, 2000 (the "OUTSIDE DATE"); PROVIDED, HOWEVER, that neither Parent
or Microsoft may terminate this Agreement pursuant to this SECTION 9.01(d) if
the Closing shall not have been consummated within such time period by reason
of the failure of such party or any of its Affiliates to perform in all
material respects any of its or their respective covenants or agreements
contained in this Agreement.

              9.02   EFFECT OF TERMINATION.  If this Agreement is terminated
as permitted by SECTION 9.01 such termination shall be without liability of
any party to any other party to this Agreement except as hereinafter
expressly provided in this SECTION 9.02.  If one party to this Agreement (i)
willfully fails to fulfill a condition to the other's performance of its
obligations hereunder, (ii) fails to perform a covenant contained herein,
(iii) willfully breaches this Agreement or (iv) materially breaches any of
its representations and warranties contained herein, such party shall be
fully responsible for all damages and expenses incurred by the other party to

                                      34
<PAGE>

this Agreement as a result of such breach or failure.  The provisions of
SECTIONS 6.02, 10.03, 10.05 and 10.11 shall survive any termination of this
Agreement pursuant to ARTICLE IX, and each party hereto shall be fully
responsible for any breach of any such provision, whether or not such breach
occurs prior to the termination of this Agreement.

negotiations, both written and oral, between the parties with respect to the
subject matter of this Agreement.  Neither this Agreement nor any provision
hereof is intended to confer upon any Person other than the parties hereto
any rights or remedies hereunder.

              10.08  CAPTIONS.  The captions herein are included for
convenience of reference only and shall be ignored in the construction or
interpretation hereof.  All references to an Article or Section include all
subparts thereof.

              10.09  SEVERABILITY.  If any provision of this Agreement, or
the application thereof to any Person, place or circumstance, shall be held
by a court of competent jurisdiction to be invalid, unenforceable or void,
the remainder of this Agreement and such provisions as applied to other
Persons, places and circumstances shall remain in full force and effect only
if, after excluding the portion deemed to be unenforceable, the remaining
terms shall provide for the consummation of the transactions contemplated
hereby in substantially the same manner as originally set forth at the later
of the date this Agreement was executed or last amended.

              10.10  CONSTRUCTION.  The parties hereto intend that each
representation, warranty, and covenant contained herein shall have
independent significance.  If any party has breached any representation,
warranty or covenant contained herein in any respect, the fact that there
exists another representation, warranty or covenant relating to the same
subject matter (regardless of the relative levels of specificity) that the
party has not breached shall not detract from or mitigate the fact that the
party is in breach of the first representation, warranty or covenant.

              10.11  ARBITRATION.

                     (a)    Any dispute or difference between or among the
parties (such parties being referred to individually as a "DISPUTING PARTY,"
and, together, as the "DISPUTING PARTIES") arising out of this Agreement or
the transactions contemplated hereby, including without limitation any
dispute between an Indemnitee and any Indemnifying Party under ARTICLE IX,
which the parties are unable to resolve themselves shall be submitted to and
resolved by arbitration as herein provided.  Any Disputing Party may request
the American Arbitration Association (the "AAA") to designate one arbitrator,
who shall be qualified as an arbitrator under the standards of the AAA, and
who shall have been engaged in the private practice of law for not less than
fifteen (15) years immediately prior to appointment as arbitrator pursuant to
this Agreement, who, in any such case, (i) is not affiliated with any party
in interest to such arbitration, (ii) is not a law firm that has within the
last three years rendered, or is then rendering, services to any party
hereto, (iii) has not appeared, or is not then appearing, as counsel of
record in opposition to any party hereto and (iv) is qualified to serve by
training for and experience in the matters for which such arbitrator is
designated to serve.

                     (b)    The arbitrator shall consider the dispute at
issue in Portland, Oregon, at a mutually agreed upon time within one hundred
twenty (120) days (or such other period as may be acceptable to the Disputing
Parties or as directed by the arbitrator) of the designation of the
arbitrator.  The arbitration proceeding shall be held in accordance with the
rules for commercial arbitration of the AAA in effect on the date of the
initial request by the Disputing Party, that gave rise to the dispute to be
arbitrated (as such rules are modified by the terms of this Agreement or may
be further modified by mutual agreement of the Disputing Parties) and shall
include an opportunity for the parties to conduct discovery in advance of the
proceeding using all of the authorized methods of discovery allowed by the
Federal Rules of Civil Procedure in effect on the date of the initial request
by the Disputing Party. Notwithstanding the foregoing, the Disputing Parties
shall agree that they will attempt, and they intend that they and the
arbitrator should use its best efforts in that attempt, to conclude the
arbitration proceeding and have a final decision from the arbitrator within
one hundred twenty (120) days from the date of selection of the arbitrator;
PROVIDED, HOWEVER, that the arbitrator shall be entitled to extend such one
hundred twenty (120) day period for a total of two one hundred twenty (120)
day periods.  The arbitrator shall be bound to follow the laws of the State
of Delaware, both decisional and statutory, in reaching any decision and
making any award and shall deliver a written award, including written
findings of fact and conclusions of law, with respect to the dispute to each
of the parties, who shall promptly act in accordance therewith.  Each
Disputing Party to such arbitration agrees that any award of the arbitrator
shall be final, conclusive and binding and that they will not contest any
action by any other party thereto in accordance with an award of the
arbitrator; PROVIDED, HOWEVER that any party may appeal based on statutory
grounds.  It is specifically understood and agreed that any party may enforce
any award rendered pursuant to the arbitration provisions of this SECTION
10.11 by bringing suit in any court of competent jurisdiction.

                     (c)    All costs and expenses attributable to the
arbitrator shall be allocated among the parties to the arbitration in such
manner as the arbitrator shall determine to be appropriate under the
circumstances.

                     (d)    The arbitrator chosen in accordance with these
provisions shall not have the power to alter, amend or otherwise affect the
terms of these arbitration provisions or the provisions of this Agreement or
any other documents that are executed in connection therewith.

                     (e)    Arbitration under this Section shall be the sole
and exclusive remedy of the parties for any dispute arising out of this
Agreement.

              10.12  CONTRIBUTIONS.  Parent covenants that Parent shall not,
nor shall Parent cause the Company to, take any action inconsistent with the
treatment of Microsoft's contributions of assets to the Company prior to the
date hereof as a tax-free exchange pursuant to Code Section 351 and the
Regulations promulgated thereunder, unless any of the parties to this
Agreement are required, pursuant to a "determination" within the meaning of
Code Section 1313(a), to treat the transaction in a different manner.  Parent
will cause its Affiliates to comply with this covenant.

              10.13  CUMULATIVE REMEDIES.  The rights, remedies, powers and
privileges herein provided are cumulative and not exclusive of any rights,
remedies, powers and privileges provided by law.

              10.14  THIRD PARTY BENEFICIARIES.  Except as specifically
provided in Article XI with respect to indemnification provided to the
Indemnitees identified therein, no provision of this Agreement shall create
any third party beneficiary rights in any Person, including any employee of
Parent or employee or former employee of Microsoft in connection with the
Business (including any beneficiary or dependent thereof).
