Closing (the "Closing Date"), at the offices of Preston Gates & Ellis LLP in
Seattle, Washington, unless another time, date, or place is agreed to in writing
by the parties hereto. Any party to this Agreement, including such party's
representative(s), may participate in the Closing telephonically.

     1.3  Effects of the Merger. At the Effective Time, (i) Sub shall be merged
          ---------------------

     1.4  Conversion of Company Securities.
          --------------------------------

          1.4.1  Company Shares.
                 --------------

          (a)  Each issued and outstanding Company Common Share and each issued
and outstanding Company Preferred Share (each as defined in Section 2.1.2
hereto), but excluding any Eligible Dissenting Shares, as defined in Section
1.10, shall, at the Effective Time, by virtue of the Merger, be converted,
without any action on the part of the holders thereof, into and Expedia shall
thereupon issue to the holders of the Company Common Shares and the Company
Preferred Shares a number of Expedia Common Shares ("Expedia Common Shares"),
pursuant to an exchange ratio ("Exchange Ratio") calculated in accordance with
the following and rounded to the nearest ten thousandth:

          (i)  Where the Expedia Closing Price (as defined below) is equal to or
     less than 40.4126 per share but greater than or equal to 25.4126 per share,
     the Exchange Ratio shall be equal to the quotient of the Adjusted Company
     Share Price (as defined in Section 1.5) divided by the Initial Expedia
     Price (as defined below);

          Solely for purposes of example, where Initial Expedia Price is $35 at
          signing and the Final Expedia Price is anywhere between $27.51 and
          $42.49 at Closing and the price per Company Share is not adjusted
          (i.e. $5.1446), the Exchange Ratio will be equal to $5.1446/$35, or
          .1470 Expedia Common Shares per Company Share Equivalent.

          (ii)  Where the Expedia Closing Price is greater than 40.4126, the
     Exchange Ratio shall be equal to the quotient of the Adjusted Company Share
     Price divided by 40.4126; and

          Solely for purposes of example, where the Initial Expedia Price is $35
          at signing and the Final Expedia Price is $50.00 at Closing and the
          price per Company Share is not adjusted (i.e. $5.1446), the Exchange
          Ratio will be equal to $5.1446/$42.50, or .1210 Expedia Common Shares
          per Company Share Equivalent.

          (iii)  In the event that upon such time as the conditions to closing
     the Merger set forth in Article VI have been satisfied or waived the
     Expedia Closing Price is less than 25.4126 but greater than 20.4126, the
     Board of Directors of the Company shall have the right to terminate this
     Agreement (such authority having been granted by the holders of Company
     Shares by approving the Merger in accordance with the DGCL), provided,

                                       2

 
     however, that no such right to terminate shall apply if Expedia shall
     offer, in its sole discretion, to deliver Expedia Common Shares at an
     Exchange Ratio equal to the quotient of the Adjusted Company Share Price
     divided by 25.4126.

          Solely for purposes of example, where the Initial Expedia Price is $35
          at signing and the Final Expedia Price is $22 at Closing and the price
          per Company Share is not adjusted (i.e. $5.1446), the Exchange Ratio
          will be equal to $5.1446/$27.50, or .1871 Expedia Common Shares per
          Company Share Equivalent.

          (iv)  In the event that upon such time as the conditions to closing
     the Merger set forth in Article VI have been satisfied or waived the
     Expedia Closing Price is less than 20.4126, the Board of Directors of the
     Company shall have the right to terminate this Agreement (such authority
     having been granted by the holders of Company Shares by approving the
     Merger in accordance with the DGCL).

          (b)  Notwithstanding the foregoing, each issued and outstanding
Company Common Share, but excluding any Eligible Dissenting Shares, held by
Holders (as defined in Section 1.4.5) who upon the conversion of Company Shares
into Expedia Common Shares set forth in subsection (a), above, would be entitled
to receive a number of Expedia Common Shares which when multiplied by the
Initial Expedia Price as of the Effective Time would be equal to $140,000 or
less, shall at the Effective Time, by virtue of the Merger, and in lieu of the
conversion set forth in subsection (a), above, be converted, without any action
on the part of the holders thereof, into the right to receive and Expedia shall
promptly thereafter deliver immediately available funds equal to the Adjusted
Company Share Price as of the Effective Time.

          (c)  Schedule 1.4 sets forth as of the date hereof: (i) the Company
Common Shares, and all other rights to purchase any securities convertible into
Company Common Shares, (ii) the number of Company Common Share Equivalents as of
such date, and (iii) a pro forma computation of the consideration payable per
Company Common Share Equivalent, the Exchange Ratio and the Expedia Common
Shares to be issued in accordance with subsection (a), above or cash deliverable
in accordance with subsection (b), above, as of the Closing using an assumed
Expedia Closing Price (as defined below) as of such date. Schedule 1.4 shall be
revised and updated as of the Closing Date using the actual Expedia Closing
Price and reflecting any changes in Company Common Share Equivalents.

          (d)  For purposes of this Agreement, the "Expedia Closing Price" shall
mean the Expedia Average Price (as defined below) as of two (2) trading days
prior to the date set for Closing in accordance with Section 1.2. For purposes
of this Agreement, the "Initial Expedia Price" shall mean the Expedia Average
Price as of two (2) trading days prior to the execution of this Agreement. For
purposes of this Agreement, "Expedia Average Price" shall mean the average price
as publicly reported for the Nasdaq Stock Market as of 4:00 p.m. Eastern Time of
Expedia Common Shares over the last five (5) trading days prior to a specified
date, rounded to the nearest one hundredth of one cent. For purposes of this
Agreement, "Company Common Share Equivalents" shall mean all Company Common
Shares (as defined in Section 2.1.2) and all other securities convertible into
and rights to purchase Company Common Shares (in each

                                       3

 
instance assuming full exercise of the right to convert into or purchase Company
Common Shares) outstanding as of immediately prior to the Closing, but excluding
Company Common Share Equivalents, if any, which expire on or before the Closing
Date.

          1.4.2  Company Options.
                 ---------------

               (a)  Not less than seventeen (17) days prior to the anticipated
Closing Date, the Company shall provide to each of the holders of then
outstanding Company Options (as defined in Section 2.1.2) notice that, in
accordance with the Company Stock Plan (as defined in Section 2.1.2) but subject
to subsection (b), immediately below, each Company Option shall be accelerated
and the holders of Company options shall be given the opportunity to exercise
their Company Options for Company Common Shares. Such notice shall provide that
exercise may be made on a "net" basis (meaning that such Company Option shall be
exercised for the number of Company Common Shares underlying such option minus
the quotient of the aggregate exercise price for such Company Options divided by
Adjusted Company Share Price. Schedule 1.4 has been prepared on the basis that
assumes that all holders avail themselves of the right to exercise on an net
basis. Any unvested Company Options held by persons other than Company employees
as of the Effective Time shall be canceled as of the Effective Time.

               (b)  Notwithstanding the provisions of subsection (a) immediately
above, any and all Company Options held by certain persons who continue as
employees of Company or Expedia in senior management positions ("Senior
Managers") or as consultants of Company or Expedia following the Closing shall
be converted into a nonqualified stock option ("Expedia Option") to purchase
Expedia Common Shares in accordance with the offer letters or consulting
agreements of such persons with Expedia.

          1.4.3  Founder Shares. The Expedia Common Shares issuable pursuant to
                 --------------
this Agreement to Thomas Breitling and Timothy Poster (the "Founders"), but
excluding the 10 percent (10%) of the shares held in escrow pursuant to Section
1.4.5, will be subject to certain other contractual restrictions set forth in
the offer letters between the Founders and Expedia.

          1.4.4  Fractional Securities. No fraction of a Expedia Common Share or
                 ---------------------
Expedia Option exercisable for a fraction of a Expedia Common Share will be
issued in the Merger. In lieu of such issuance, all Expedia Common Shares issued
to the Company shareholders shall be rounded to the closest whole Expedia Common
Share, and the number of Expedia Common Shares subject to any Expedia Option
shall be rounded to the nearest whole number of Expedia Common Shares.

          1.4.5  Escrow Securities. Ten Percent (10%) of the Expedia Common
                 -----------------
Shares to be issued in the Merger shall be held by the Escrow Agent pursuant to
the Escrow Agreement attached as Exhibit 1.4.5 ("Escrow Agreement") to secure
claims by Expedia for indemnification pursuant to Article VII hereof. For
avoidance of doubt, the ten percent (10%) of Expedia Common Shares to be held in
escrow shall include Founder Shares and shares received upon exercise vested and
accelerated Company Options, but shall not include unvested Company Options to
be converted upon the Effective Time into Expedia Options, and cash received in
lieu of Expedia common Shares in accordance with Section 1.4.1(b) shall not be
subject to escrow.

                                       4

 
The Expedia Common Shares to be held on behalf of the holders of Company Common
Shares and Expedia Preferred Shares as of the Effective Time (collectively, the
"Holders") are set forth on Schedule 1.4 on a pro forma basis which shall be
revised as of Closing. Execution of the Escrow Agreement by each Holder
receiving Expedia Common Shares under Section 1.4.1(a) (or any attorney in fact
appointed by such Holder) is a condition precedent to receiving the Expedia
Common Shares by such Holder.

     1.5  Price Per Company Share. The term "Adjusted Company Share Price" shall
          -----------------------
mean Five United States Dollars and Fourteen and Fourty Six Hundredths Cents
(U.S.$5.1446) per Company Share and Company Share Equivalent, provided that, in
the event that the Company's Net Liabilities, as defined below, set forth on the
Company's Final Pro Forma Closing Balance Sheet (as defined in Section 2.1.6
hereof) are greater than the amount of Net Liabilities set forth on the balance
sheet in the Company's Financial Statements (as defined in Section 2.1.6) of
December 31, 1999 (the amount of such difference being hereinafter referred to
as "Increased Liabilities"), then the Adjusted Company Share Price shall be
equal to the product of $5.1446 multiplied by a fraction, the numerator of which
is $100,000,000 minus the Increased Liabilities and the denominator of which is
$100,000,000. For purposes of the foregoing, "Net Liabilities" as of December
31, 1999 shall mean total liabilities, less the sum of (a) deferred revenue,
accounts payable and accrued expenses up to 70% of previous 90 days gross
bookings, plus (b) Current assets at December 31, 1999; and "Net Liabilities" on
the Company's Final Pro Forma Closing Balance Sheet shall mean total
liabilities, less the sum (a) deferred revenue, accounts payable and accrued
expenses up to 70% of previous 90 days gross bookings, plus (b) Adjusted Current
Assets (as defined below) at the Closing. "Adjusted Current Assets" shall be
computed as follows: Current assets plus: (i) capital expenditures of up to
$166,667 per month made between December 31, 1999 and Closing, (ii) expenses
incurred that are directly attributable to this transaction up to the amount set
forth on the estimate delivered under Section 5.4, (iii) security deposits made
between December 31, 1999 and Closing, and (iv) beginning in March 2000, the
expected EBITDA loss of $927,226 in March 2000 and $714,362 in April 2000 (for
purposes of this calculation, the Closing date will be rounded to the nearest
half month). In the event that the certain Engagement Letter between CIBC World
Markets and Company dated July 2, 1999, shall not be terminated or released in
full to the reasonable satisfaction of Expedia on or prior to Closing, the
Adjusted Company Share Price shall be further adjusted to be equal to the
product of the Adjusted Company Share Price calculated in accordance with the
above multiplied by .9868.

     1.6  Delivery of Certificates or Cash. At or as soon as practicable after
          --------------------------------
the Effective Time, Expedia will send to the holders of Company Shares (i) a
letter of transmittal in customary form and containing such provisions as
Expedia may reasonably specify (including a notice of election to opt out of
registering for sale Expedia Common Shares subject to registration under Section
1.9.2), and (ii) instructions for use in effecting the surrender of certificates
representing Company Shares in exchange for either certificates representing
Expedia Common Shares or cash in accordance with Section 1.4.1. After the
Effective Time, and after receiving such letter of transmittal, each Shareholder
of a certificate or other documentation representing Company Shares, other than
Eligible Dissenting Shares, shall surrender such certificates or other
documentation to Expedia or the exchange agent designated by Expedia and letter
of transmittal, and those Holders whose Company Shares are converted into
Expedia Common Shares under

                                       5

 
Section 1.4.1(a) shall in addition deliver duly executed counterparts of the
Investment Agreement (as defined in Section 5.1) and Escrow Agreement and such
other duly executed documentation as may be reasonably required by Expedia or
the exchange agent to effect a transfer of such shares. Promptly following such
surrender and delivery each Holder shall be entitled to receive either a
certificate or other documentation for the applicable number of Expedia Common
Shares calculated pursuant to Section 1.4.1(a), except as provided in Section
1.4.5, or cash calculated pursuant to Section 1.4.1(b), which shall be delivered
by check. If any certificate representing Company Shares shall have been lost,
stolen or destroyed, Expedia may, in its discretion and as a condition precedent
to the delivery of consideration hereunder, require the owner of such lost,
stolen or destroyed certificate representing Company Shares to provide an
appropriate affidavit and indemnity against any claim that may be made against
Expedia or the Surviving Corporation with respect to such certificate
representing Company Shares. Execution and delivery of an Escrow Agreement and
an Investment Agreement shall be a condition precedent to the issuance of the
Expedia Common Shares to each Holder whose Company Shares are converted into
Expedia Common Shares under Section 1.4.1(a).

     1.7  Tax-Free Reorganization. The Merger is intended to be a
          -----------------------
"reorganization" within the meaning of Section 368 of the Internal Revenue Code
of 1986, as amended (the "Code"), and this Agreement is intended to constitute a
"plan of reorganization" within the meaning of the regulations promulgated under
Section 368 of the Code. Notwithstanding the foregoing, no party shall be
relieved of any obligation or denied any right set forth hereunder in the event
it is determined that the tax consequences differ from those intended or those
described in the solicitation statement/private placement memorandum (if any) or
otherwise.

     1.8  No Further Ownership Rights in Company Common Shares or Company
          ---------------------------------------------------------------
Options. All Expedia Common Shares issued on or after the Effective Time upon
-------
cancellation of the Company Common Shares or replacement of the Company Options
in accordance with the terms hereof shall respectively be deemed to have been
delivered in full satisfaction of all rights pertaining to the Company Common
Shares or the Company Options. After the Effective Time, there shall be no
transfers on the stock transfer books of Company of the Company Common Shares or
the Company Options.

     1.9  Regulation D and Registration Statements.
          ----------------------------------------

          1.9.1  Regulation D Offering. Each holder of Company Shares shall
                 ---------------------
execute such documents as may be reasonably required by Expedia to determine
such holder's qualification as an "accredited investor," as that term is defined
in Rule 501 of Regulation D under the Securities Act of 1933 (the "1933 Act") or
as a person with the financial sophistication required to be a purchaser
pursuant to Rule 506(b)(2)(ii) of Regulation D. Company agrees, if required
under the provisions of Rule 506, to provide, at its sole expense, any
shareholder reasonably determined by Expedia as not having the requisite
financial sophistication with a purchaser representative who can provide such
shareholder with the requisite financial sophistication.

          1.9.2  Registration Rights.
                 -------------------

                                       6

 
               (a)  Expedia shall prepare and file with the Securities and
Exchange Commission registration statements on the form under the 1933 Act that
Expedia determines to be the least burdensome available (such registration
statement and the prospectus included therein being referred to as the
"Registration Statement", regardless of the form actually used) to register for
resale Expedia Common Shares issued in the Merger to the Company shareholders,
and their permitted transferees (collectively, the "New Expedia Shareholders"),
and shall use its commercially reasonable efforts to have pursuant to this
paragraph (a) no more than one such Registration Statement declared effective
under the 1933 Act by and kept continuously effective during the following dates
and upon the following conditions:

               (i)  From May 15, 2000 through June 16, 2000, provided that
Expedia shall receive a demand for registration as of such dates from holders of
not less than twenty five percent (25%) of the Expedia Common Shares issued in
the Merger on or prior to April 1, 2000 if the Effective Time has occurred prior
to April 1, 2000 or April 8, 2000 if the Effective Time has occurred after April
1, 2000 and on or prior to April 8, 2000.

               (ii)  From August 1, 2000 through August 13, 2000, provided that
Expedia shall receive a demand for registration as of such dates from holders of
not less than twenty five percent (25%) of the Expedia Common Shares issued in
the Merger after April 8, 2000 and on or prior to July 1, 2000 and, provided
that no Registration Statement was made effective pursuant to subsection (i),
above, unless such lack of effectiveness resulted from a withdrawal of the
demand for such registration or the failure of the holders of Expedia Common
Shares making such demand to provide to Expedia the requisite information for
such filing or through other fault of the holders of Expedia Common Shares.

Upon receipt of a demand under (i) or (ii) above, Expedia shall within five (5)
business days thereafter deposit with the United States post office or national
courier service notice to holders making such demand of Expedia's election
whether the Registration Statement to be filed shall be for an underwritten
secondary offering, an underwritten primary offering by Expedia in which holders
issuing such demand shall be permitted to participate, or a secondary offering
under Section 415 under the 1933 Act.  An underwritten primary offering by
Expedia may include an offering of Expedia Common Shares, derivative instruments
that are economically substantially equivalent to Expedia Common Shares, or
securities convertible into either Expedia Common Shares or derivative
instruments that are economically substantially equivalent to Expedia Common
Shares. Should Expedia elect to undertake any such underwritten primary offering
after receiving a demand under subsection (i), Expedia will include in such
registration first, the aggregate number of securities to be issued by Expedia,
and second, as many of the shares of Expedia Common Shares covered by the demand
made under (i) as the managing underwriter shall determine is its sole
discretion are permitted by market conditions, provided that in no event shall
the shares of such holders included in such demand be less than the greater of
(A) 15% of the Expedia Common Shares issuable under the Registration Statement
for such offering or (B) Expedia Common Shares with a value of $22.5 million at
the time of such offering, provided that no more than 750,000 shares shall be
registered pursuant to this clause (B). Expedia shall select the managing
underwriters for any underwritten offering made pursuant to this subsection in
its sole discretion.  Each Registration Statement shall list as selling

                                       7

 
shareholders each New Expedia Shareholder still holding Expedia Common Shares
that has (A) provided to Expedia the requisite information for such filing and
(B) requested to be included in such demand on or prior to last date required to
make such request.  Notwithstanding the foregoing, if Expedia shall furnish the
New Expedia Shareholders entitled to be listed as selling shareholders on a
Registration Statement under this subsection a certificate signed by an officer
of Expedia stating that in the good faith judgment of the Board of Directors of
Expedia, it would be detrimental to Expedia for such Registration Statement to
be filed or made effective, then Expedia shall have the right to defer such
filing or the effective date of such Registration Statement until the next date
upon which Expedia would be obligated to use its commercially reasonable efforts
to make a Registration Statement effective, provided that Expedia shall not have
the right to defer any such filing more than once.

               (b) If at any time after the Effective Time, Expedia proposes to
register any Expedia Common Shares, derivative instruments that are economically
substantially equivalent to Expedia Common Shares, or securities convertible
into either Expedia Common Shares or derivative instruments that are
economically substantially equivalent to Expedia Common Shares under the 1933
Act on any Registration Statement (other than a registration statement subject
to Section 1.9.2 (b)) prescribed by the Securities Exchange Commission, which
registration shall permit a public secondary offering or distribution (other
than any form solely for registration of securities issuable pursuant to
employee equity or option ownership plans or as consideration for business
combinations), not less than thirty (30) days prior to each such registration,
Expedia shall give to the New Expedia Shareholders written notice of such
proposal which shall describe in detail the proposed registration and
distribution and, upon the written request of any New Expedia Shareholders given
within fifteen (15) days after the date of any such notice, provided that such
holders shall have provided to Expedia the requisite information for such
filing, proceed to include in such registration such Expedia Common Shares as
have been requested by any such holder to be included in such registration.
Expedia will in each instance use its commercially reasonable efforts to cause
Expedia Common Shares subject to such request to be registered under the 1933
Act; provided, that in the event such registration is an underwritten primary
offering on behalf of Expedia and the managing underwriters advise Expedia in
writing that, in their opinion, the number of securities requested to be
included in such registration exceeds the number which can be sold in such
offering, Expedia will include in such registration (i) first, the aggregate
number of securities to be issued by Expedia, (ii) second, the shares of Expedia
common stock registrable under any demand for registration giving rise to the
right of registration of New Expedia Shareholders under this subsection (b); and
(iii) third, Expedia Common Shares requested to be included in such registration
under this subsection (b) together with other securities requested to be
included in such registration, such shares to be treated on a pro rata basis.
Expedia shall select the managing underwriters for any offering made pursuant to
this subsection (b) in its sole discretion.

               (c) As soon as practicable after Form S-3 becomes available to
Expedia, provided that Expedia Common Shares held by New Expedia Shareholders
remain outstanding at such time, Expedia shall prepare and file with the
Securities Exchange Commission a Registration Statement on Form S-3 to register
for resale Expedia Common Shares issued in the Merger to the New Expedia
Shareholders. Expedia shall use its commercially

                                       8

 
reasonable efforts to have such Registration Statement declared effective under
the 1933 Act as promptly as practicable after such filing. Expedia shall use its
commercially reasonable efforts to cause such registration statement to continue
to be effective and the prospectus contained therein to be updated as reasonably
deemed necessary by Expedia to enable the New Expedia Shareholders to resell the
Expedia Common Shares that were issued in the Merger.

               (d) Expedia shall use its commercially reasonable efforts to
cause any Registration Statement filed under Sections 1.9.2(a), 1.9.2(b) and
1.9.2(c) to continue to be effective during the time specified for such and the
prospectus contained therein to be updated during such time to enable the New
Expedia Shareholders making a demand for registration under subsection (a) or
exercising their rights under subsection (b) or entitled to registration under
subsection (c) to resell during such time the Expedia Common Shares that were
issued in the Merger over the Nasdaq Stock Market or such other national market
as Expedia Common Shares may be traded. Expedia shall also endeavor to take any
action required to be taken under any applicable state securities laws in
connection with the issuance of Expedia Common Shares in the Merger and the
resale of those shares pursuant to the Registration Statement. Expedia agrees to
use its commercially reasonable efforts to cause the Expedia Common Shares
covered by the Registration Statement to be registered with or approved by such
other governmental agencies or authorities as may be necessary to enable the
holders of such Expedia Common Shares to consummate the disposition of such
Expedia Common Shares and cause all such Expedia Common Shares to be listed on

with respect to the Merger and to be paid the fair value of such shares in
accordance with Section 262 et seq. of the DGCL and, as of the Effective Time,
has not effectively withdrawn or lost such appraisal rights, shall not be
converted into or represent a right to receive the Merger Consideration, but the
holder thereof shall be entitled only to such rights as are granted by the DGCL

notice of any notice of intent to demand appraisal for any Company Shares,
withdrawals of such notices, and any other instruments served pursuant to the

                                INDEMNIFICATION
                                        

     7.1  Indemnification Relating to Agreement. The Holders (other than the
          -------------------------------------
Principal Shareholders), by reason of the approval by the Holders of the Merger
and/or each Holder's acceptance of the consideration provided for in Section 1.4
and by the execution of the Escrow Agreement pursuant to Section 1.4.4 which is
a condition to receiving such consideration, severally but not jointly, and the
Principal Shareholders, jointly and severally, shall, agree to defend,
indemnify, and hold Expedia harmless from and against, and to reimburse Expedia
with respect to, any and all losses, damages, liabilities, claims, judgments,
settlements, fines, costs, and expenses (including attorneys' fees)
("Indemnifiable Amounts") of every nature whatsoever incurred by Expedia by
reason of or arising out of or in connection with (i) any breach, or any claim
(including claims by parties other than Expedia) that if true, would constitute
a breach, by Company or the Principal Shareholders of any representation or
warranty of Company or the Principal Shareholders contained in this Agreement or
in any certificate or other document delivered to Expedia pursuant to the
provisions of this Agreement, (ii) the failure, partial or total, of Company or
the Principal Shareholders to perform any agreement or covenant required by this
Agreement to be performed by it or them, (iii) any action or omission by
Company, the Principal Shareholders, their affiliates, agents or representatives
relating to this Agreement, and (iv) any federal or state tax liability, or
asserted liability of the Company relating to any period of time prior to and
through the Closing which is not disclosed in the Financial Statements or the
Final Pro Forma Closing Balance Sheet, and in each case without giving effect to
any "materiality" limitations or references to "material adverse effect" set
forth therein. The obligations of any Holder to indemnify Expedia shall be
determined without regard to any right to indemnification to which any Holder
may have in his or her capacity as an officer, director, employee, agent or any
other capacity of Company and no Holder shall be entitled to any indemnification
from Company or the Surviving Corporation for amounts paid hereunder. There
shall be no right of contribution from Company or any successor to Company.

     7.2  Claims for Indemnification. With respect to any claims or demands by
          --------------------------
third parties, other than claims or demands covered by Section 7.3, whenever
Expedia shall have received a written notice that such a claim or demand has
been asserted or threatened, or whenever Expedia shall seek indemnification
pursuant to this Article VII, Expedia shall notify the "Holders' Representative"
(as designated in the Escrow Agreement) of such claim or demand and of the facts
within Expedia's knowledge that relate thereto within a reasonable time after
receiving such written notice. The Holders' Representative shall then have the
right to contest, negotiate or settle any such claim or demand through counsel
of his own selection, satisfactory to Expedia and solely at the Holders' own
cost, risk, and expense. Notwithstanding the preceding sentence, the Holders
shall not settle, compromise, or offer to settle or compromise any such claim or
demand without the prior written consent of Expedia, which consent shall not be
unreasonably withheld. By way of illustration and not limitation it is
understood that Expedia may object to a settlement or compromise which includes
any provision which in its reasonable judgment may have an adverse impact on or
establish an adverse precedent for the Business Condition of Expedia or any of
its Subsidiaries. Expedia shall not have the right to object to a settlement
which consists solely of the payment of a monetary damage amount and which is
subject to full indemnification under this Agreement. If the Holders'
Representative fails to give

                                       42

 
written notice to Expedia of his intention to contest or settle any such claim
or demand within twenty (20) calendar days after Expedia has notified the
Holders' Representative that any such claim or demand has been made in writing
and received by Expedia, or if any such notice is given but any such claim or
demand is not promptly contested by the Holders' Representative, Expedia shall
have the right to satisfy and discharge the same by payment, compromise, or
otherwise, in accordance with the procedures set forth in the Escrow Agreement.
Expedia may also, if it so elects and entirely within its own discretion, defend
any such claim or demand if the Holders' Representative fails to give notice of
his intention to contest or settle any such claim or demand, in which event
Expedia and its affiliates shall be entitled to indemnification to the full
extent of the Total Escrow (as defined in the Escrow Agreement ) for any and all
costs, losses, liabilities, and expenses whatsoever, including without
limitation reasonable attorneys' and other professional fees, that Expedia may
sustain, suffer, incur, or become subject to as a result of Expedia's decision
to defend any such claim or demand.

     7.3  Tax Contests. Notwithstanding any of the foregoing, the Holders shall
          ------------
have no right to control any federal or state income tax audit, and Expedia
shall have the sole right to conduct any tax audit or other tax contest relating
to the Expedia tax return, subject to the provisions of this paragraph.
Notwithstanding the foregoing, in the event of any audit of the reorganization
of the Company effected January 21, 1999, Expedia shall have no right to control
such audit, and the Principal Shareholders shall have the sole right to conduct
any tax audit or other tax contest relating to such, subject to the provisions
of this paragraph. The party controlling the response to an audit under this
paragraph shall (A) consult with the other parties with respect to the
resolution of any issue that would affect such other parties in that or any
other taxable year, and (B) not settle any such issue, or file any amended
Return relating to such issue, without the consent of the other parties, which
consent shall not unreasonably be withheld. Where consent to a settlement is
withheld by another party pursuant to clause (B) of the preceding sentence, such
other party may continue or initiate any further proceedings at its own expense,
provided, that the liability of the first party, after giving effect to this
Agreement, shall not exceed the liability that would have resulted from the
settlement or amended return. In the event any Indemnifiable Amounts arise out
of such tax audits, the party controlling such audit will notify the other party
and the Holders' Representative and allow him to comment on any written
submissions relating to any Indemnifiable Amounts.

     7.4  Limitations. The representations, warranties, covenants and agreements
          -----------
of Company and the Principal Shareholders set forth in this Agreement shall
survive the Closing and the consummation of the transactions contemplated by
this Agreement and shall continue until September 30, 2001 (the "Termination
Date"), at which time all representations and warranties shall expire, provided,
however, that the obligation to indemnify Expedia for breaches of the
representations, warranties and covenants in Sections 2.1.7 and 5.8 relating to
taxes (as defined in Section 2.1.7) shall continue until thirty (30) days after
the expiration of all statutes of limitations applicable to such taxes.
Notwithstanding any other provision in this Article VII, Indemnifiable Amounts
to be paid by the Holders and Principal Shareholders shall be satisfied solely
by the securities deposited into escrow pursuant to Section 1.4.5, provided that
(i) the representations, warranties and covenants in Sections 2.1.7 and 5.8

in January 1999, if any, and (ii) obligations of the Principal Shareholders for

willful omissions or fraud of Company or the Principal Shareholders shall not be
subject to such limitation.

     7.5  Binding Effect. The indemnification obligations of the Holders

of, or constitute a waiver of, any remedies at law or in equity that Expedia may

by such persons, including without limitation claims arising out of willful
misstatements, willful omissions or fraud of Company or the Principal
Shareholders.

     7.7  Tax Consequences. As stated in Section 1.7, it is the intent of the
          ----------------
parties that the Merger is intended to be a "reorganization" within the meaning
of Section 368 of the Code; however, except as otherwise provided in Section
7.8, no party or its counsel shall have any obligation, of indemnification or
otherwise, in the event it is determined that the tax consequences differ from
those intended or those described in the solicitation statement/private
placement memorandum or otherwise.

     7.8  Indemnity by Expedia. Expedia agrees to defend, indemnify, and hold
          --------------------

     Such addresses may be changed, from time to time, by means of a notice
given in the manner provided in this Section 9.3.

     9.4  Severability. If any provision of this Agreement is held to be
          ------------
unenforceable for any reason, it shall be modified rather than voided, if
possible, in order to achieve the intent of the parties to this Agreement to the
extent possible. In any event, all other provisions of this Agreement shall be
deemed valid and enforceable to the full extent. If it is ever held that any
covenant hereunder is too broad to permit enforcement of such covenant to its
fullest extent, each party agrees that a court of competent jurisdiction may
enforce such covenant to the maximum

                                       46

 
extent permitted by law, and each party hereby consents and agrees that such
scope may be judicially modified accordingly in any proceeding brought to

warranties contained in this Agreement, including the exhibits and schedules

     9.6  Assignment. No party to this Agreement may assign, by operation of law
          ----------
or otherwise, all or any portion of its rights, obligations, or liabilities
under this Agreement without the prior written consent of the other party to
this Agreement, which consent may be withheld in the absolute discretion of the
party asked to grant such consent. Any attempted assignment in violation of this
Section 9.6 shall be voidable and shall entitle the other party to this
Agreement to terminate this Agreement at its option in addition to any and all
other remedies that may be available to such party at law or in equity. Subject
to the preceding sentence, this Agreement will be binding upon, inure to the
benefit of and be enforceable by the parties and their respective successors and
assigns.

     9.7  Counterparts. This Agreement may be executed in two or more partially
          ------------
or fully executed counterparts each of which shall be deemed an original and
shall bind the signatory, but all of which together shall constitute but one and
the same instrument. The execution and delivery of a Signature Page - Agreement
and Plan of Reorganization in the form annexed to this Agreement by any party
hereto who shall have been furnished the final form of this Agreement shall
constitute the execution and delivery of this Agreement by such party.

     9.8  Amendment. This Agreement may not be amended except by an instrument
          ---------
in writing signed on behalf of each of the parties hereto.

     9.9  Extension, Waiver. At any time prior to the Effective Time, any party
          -----------------
hereto may, to the extent legally allowed: (i) extend the time for the
performance of any of the obligations or other acts of the other party hereto,
(ii) waive any inaccuracies in the representations and warranties made to such
party contained herein or in any document delivered pursuant hereto, and (iii)
waive compliance with any of the agreements, covenants or conditions for the
benefit of such party contained herein. Any agreement on the part of a party
hereto to any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party.

     9.10  Interpretation. When a reference is made in this Agreement to
           --------------
Sections, Exhibits or Schedules, such reference shall be to a Section, Exhibit
or Schedule to this Agreement unless otherwise indicated. The words "include,"
"includes," and "including" when used therein shall be deemed in each case to be
followed by the words "without limitation." The table of contents, index to
defined terms, references to sections of the Company Disclosure Schedule or
Expedia Disclosure Schedule, and headings contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement. The phrase "made available" in this Agreement
shall mean that the information referred to has been made available, if
requested, by the party to whom such information is to be

                                       47

 
made available. The phrase "the date of this Agreement", "the date hereof" and
terms of similar import, unless the context otherwise requires, shall be deemed
to refer to January 30, 2000.

     9.11  Confidentiality. Company and the Principal Shareholders agree to keep
           ---------------
confidential and not to disclose the terms and conditions of this Agreement
specifically including, without limitation, the price payable per share of
Company Common Stock Equivalents, the aggregate consideration payable hereunder
and number of Expedia Common Shares to be issued and to advise all Company
officers, directors, stockholders and employees (and counsel to Company and its
stockholders) of this obligation and to indemnify and hold Expedia harmless from
any breach of this agreement in accordance with the provisions of Article VII.

     9.12  Arbitration. The parties shall endeavor to resolve all disputes by
           -----------
agreement and to that end shall each provide the other with sufficient
descriptions and information regarding its position to permit informed
assessments and decisions. Any disagreement, claim, demand, controversy, or
dispute which arises after the Closing in any way relating to this Agreement and
the performance or alleged breach by the parties, whether involving questions of
law or fact or both and regardless of the nature thereof or the remedy therefor,
which is not settled by agreement of the parties shall be resolved pursuant to
the arbitration provisions in Section 2.3.3 of the Escrow Agreement.
