                     AGREEMENT AND PLAN OF REORGANIZATION


     THIS AGREEMENT AND PLAN OF REORGANIZATION (the "AGREEMENT") is made and
entered into as of January 8, 1999 among Ticketmaster Online - CitySearch, Inc.,
a Delaware corporation ("PARENT"), Nero Acquisition Corporation, a California
corporation and a wholly-owned subsidiary of Parent ("Sub"), CityAuction, Inc.,
a California corporation (the "COMPANY"), and Andrew Rebele and Monica Lee,
individuals and principal shareholders of the Company (the "PRINCIPAL
SHAREHOLDERS").


                                    RECITAL

     The Boards of Directors of each of the Company, Parent and Sub believe it
is in the best interests of each company and their respective shareholders that
the Company and Sub combine into a single company through the merger of Sub with
and into the Company (the "MERGER") pursuant to the terms of this Agreement and,
in furtherance thereof, have approved the Merger.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth herein, and for other good and valuable consideration, the parties agree
as follows:


                                   SECTION 1

                                  THE MERGER

     1.1   MERGER; EFFECTIVE TIME.  Subject to the terms and conditions of this
           ----------------------                                              
Agreement and the Agreement of Merger attached as Exhibit A (the "MERGER
                                                  ---------             
AGREEMENT"), Sub will be merged into the Company (the "MERGER") in accordance
with the California Corporation Code (the "CALIFORNIA CODE").  The Merger
Agreement provides, among other things, the mode of effecting the Merger and the
manner and basis of converting each issued and outstanding share of capital
stock of the Company into shares of Class B common stock, $.01 par value, of
Parent ("PARENT COMMON STOCK").

           Subject to the provisions of this Agreement and the Merger Agreement,
the Merger Agreement, together with required officers' certificates, shall be
filed in accordance with the California Code on the Closing Date (as defined in
Section 1.2).  The Merger shall become effective upon confirmation of such
filing of the Merger Agreement and such officers' certificates (the date of
confirmation of such filing is referred to as the "EFFECTIVE DATE" and the time
of confirmation of such filing is referred to as the "EFFECTIVE TIME").

     1.2   CLOSING.  The closing of the Merger (the "CLOSING") will take place
           -------                                                            
as soon as practicable on the first business day after satisfaction or waiver of
the latest to occur of the 
<PAGE>
 
conditions set forth in Section 6 (the "CLOSING DATE"), at the offices of Wilson
Sonsini Goodrich & Rosati, 650 Page Mill Road, Palo Alto, California 94304-1050,
unless a different date or place is agreed to in writing by the parties hereto.

     1.3   EFFECTS OF THE MERGER.  At the Effective Time, the separate existence
           ---------------------                                                
of Sub shall cease and Sub shall be merged with and into the Company, and the
effects of the Merger shall be as provided in this Agreement, the Merger
Agreement and the applicable provisions of the California Code.  The Company
after the Merger is sometimes referred to as the "SURVIVING CORPORATION."
Without limiting the generality of the foregoing, and subject thereto, at the
Effective Time, all the property, rights, privileges, powers and franchises of
the Company and Sub shall vest in the Surviving Corporation, and all debts,
liabilities, obligations and duties of the Company and Sub shall become the
debts, liabilities, obligations and duties of the Surviving Corporation.

     1.4   ARTICLES OF INCORPORATION; BYLAWS; DIRECTORS; OFFICERS.  At the
           ------------------------------------------------------         
Effective Time, (i) the Articles of Incorporation of the Company shall be the
Articles of Incorporation of the Surviving Corporation; (ii) the Bylaws of the
Company as in effect immediately prior to the Effective Time shall be the Bylaws
of the Surviving Corporation until altered, amended or repealed; (iii) the
directors of Sub shall be the initial directors of the Surviving Corporation and
will hold office from the Effective Time until their respective successors are
duly elected or appointed and qualified in the manner provided in the Articles
of Incorporation and Bylaws of the Surviving Corporation, as the same may be
amended from time to time or otherwise as provided by law; and (iv) the officers
of the Company shall be the initial officers of the Surviving Corporation.

     1.5   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").  The parties have consulted with their own tax
advisors regarding the Merger.


                                   SECTION 2

               EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE
              CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

     2.1   EFFECT ON CAPITAL STOCK.  As of the Effective Time, by virtue of the
           -----------------------                                             
Merger and without any action on the part of the holder of any shares of capital
stock of the Company:

           (a)  Capital Stock of Sub.  Each issued and outstanding share of
                --------------------                                       
capital stock of Sub shall continue to be issued and outstanding and shall be
converted into one share of validly issued, fully paid and non-assessable Common
Stock of the Surviving Corporation.  Each stock certificate of Sub evidencing
ownership of any such shares shall continue to evidence ownership of such shares
of capital stock of the Surviving Corporation.

                                      -2-
<PAGE>
 
          (b)  Cancellation of Certain Shares of Capital Stock of the Company.
               --------------------------------------------------------------  
All shares of capital stock of the Company that are owned directly or indirectly
by the Company shall be canceled and no stock of Parent or other consideration
shall be delivered in exchange therefor.

          (c)  Conversion of Capital Stock of the Company.  Subject to Sections
               ------------------------------------------                      
2.1(d), (e), (f), (g) and (h) below, each issued and outstanding share of common
stock of the Company, .01 par value ("COMPANY COMMON STOCK") (other than shares
to be canceled pursuant to Section 2.1(b)), that are issued and outstanding
immediately prior to the Effective Time shall automatically be canceled and
extinguished and converted, without any action on the part of the holder
thereof, into the right to receive 0.28195 shares of Parent Common Stock.  All
such shares of Company Common Stock, when so converted, shall no longer be
outstanding and shall automatically be canceled and retired and shall cease to
exist, and each holder of a certificate representing any such shares shall cease
to have any rights with respect thereto, except the right to receive the shares
of Parent Common Stock to be issued or paid in consideration therefor upon the
surrender of such certificate in accordance with Section 2.2 of this Agreement.
The ratio pursuant to which each share of Company Common Stock will be exchanged
for shares of Parent Common Stock, determined in accordance with the foregoing
provisions, is referred to as the "EXCHANGE RATIO."

          (d)  Adjustment of Exchange Ratio.  If, between the date of this
               ----------------------------                               
Agreement and the Effective Time, the outstanding shares of Parent Common Stock
(or, subject to Section 5.1 below, Company Common Stock) shall have been changed
into a different number of shares or a different class by reason of any
reclassification, split-up, stock dividend, stock combination, then the Exchange
Ratio shall be correspondingly adjusted.

          (e)  Dissenters' Rights.  Any shares of Company Common Stock held by a
               ------------------                                               
holder who has properly exercised dissenters' rights for such shares in
accordance with the California Code and who, as of the Effective Time, has not
effectively withdrawn or lost such dissenters' rights ("DISSENTING SHARES")
shall not be converted into Parent Common Stock but shall be converted into the
right to receive such consideration as may be determined to be due with respect
to such Dissenting Shares pursuant to the California Code.  The Company shall
give Parent prompt notice of any demand received by the Company to require the
Company to purchase shares of Company Common Stock, and Parent shall have the
right to participate in all negotiations and proceedings with respect to such
demand.  The Company agrees that, except with the prior written consent of
Parent, or as required under the California Code, it will not voluntarily make
any payment with respect to, or settle or offer to settle, any such purchase
demand.  Each holder of Dissenting Shares (a "DISSENTING SHAREHOLDER") who,
pursuant to the provisions of the California Code, becomes entitled to payment
of the value of shares of Company Common Stock shall receive payment therefor
(but only after the value therefor shall have been agreed upon or finally
determined pursuant to such provisions).  In the event of legal obligation,
after the Effective Time, to deliver shares of Parent Common Stock to any holder
of shares of Company Common Stock who shall have failed to make an effective
purchase demand or shall have lost its status as a 

                                      -3-
<PAGE>
 
Dissenting Shareholder, Parent shall issue and deliver, upon surrender by such
Dissenting Shareholder of such holder's certificate or certificates representing
shares of capital stock of the Company, the shares of Parent Common Stock to
which such Dissenting Shareholder is then entitled under this Section 2.1 and
the Merger Agreement.

          (f)   Fractional Shares.  No fractional shares of Parent Common Stock
                -----------------                                              
shall be issued, but in lieu thereof each holder of shares of Company Common
Stock who would otherwise be entitled to receive a fraction of a share of Parent
Common Stock shall receive from Parent an amount of cash equal to the per share
market value of Parent Common Stock (based on the last sales price of Parent
Common Stock as reported on the Nasdaq National Market on the Effective Date)
multiplied by the fraction of a share of Parent Common Stock to which such
holder would otherwise be entitled.  The fractional share interests of each
shareholder of the Company shall be aggregated, so that no Company shareholder
shall receive cash in an amount greater than the value of one full share of
Parent Common Stock.

          (g)   Maximum Merger Consideration.  The maximum consideration to be
                ----------------------------                                  
paid by Parent (including Parent Common Stock to be reserved for issuance upon
exercise of the Company's options assumed by Parent pursuant to Section 5.16)
pursuant to the Merger shall be equal to (i) 800,000 shares of Parent Common
Stock (plus any additional shares of Parent Common Stock exchanged in the Merger
at the Exchange Ratio for shares of capital stock of the Company issued upon
exercise of the Warrant (as defined in section 3.2)) plus (ii) an additional
200,000 shares of Parent Common Stock to be reserved for issuance upon exercise
of options to purchase Parent Common Stock to be granted to the employees of
CityAuction as set forth in Section 2.1 (i)(b) below.  No adjustment shall be
made in the aggregate consideration to be paid in the Merger as a result of any
cash proceeds received by the Company from the date of this Agreement to the
Closing Date pursuant to the exercise of currently outstanding options to
acquire Company Common Stock.

           (h)  Pledged Shares.
                -------------- 

                (i)   As collateral security for the payment of any
indemnification obligations of the shareholders of the Company (the
"SHAREHOLDERS") pursuant to Section 7 of this Agreement, at the Closing the
Company shall, and by execution hereof does hereby, transfer, pledge and assign
to Parent, for the benefit of Parent, a security interest in the following
assets:

                      (A)  75,000 shares of Parent Common Stock issuable by
Parent in the Merger pursuant to Section 2.1 (the "PLEDGED SHARES"), as well as
the certificates and instruments representing or evidencing the Pledged Shares,
and all non-cash dividends and other property at any time received or otherwise
distributed in respect of or in exchange or substitution for any or all of the
Pledged Shares; and in the event the Company or any Shareholder receives any
such property, the Company and such Shareholder shall immediately deliver such
property to Parent as part of the Pledged Shares; and

                                      -4-
<PAGE>
 
                      (B)  all rights, titles, interests, privileges and
preferences appertaining or incident to the foregoing property, except as
provided for in Section 1.2(h)(iii).

                      The Pledged Shares shall be withheld from the shareholders
in relation to the prorated percentage of shares of Company Common Stock
issuable to such shareholders in the Merger as set forth in Section 2.1 (c).

               (ii)   Each certificate evidencing the Pledged Shares issued in
the names of the Shareholders in the Merger, shall, at the Closing, be delivered
to Parent, together with an undated stock power duly signed in blank by each
such Shareholder, such certificate bearing no restrictive or cautionary legend
other than those imprinted by the Transfer Agent at Parent's request.

               (iii)  The Shareholders shall be entitled to exercise any voting
powers incident to the Pledged Shares until such time, if ever, that they are
demanded to be transferred to Parent to satisfy the indemnification obligations
of the Shareholders pursuant to Section 7 hereof.

          (i)  Stock Options.
               ------------- 

               (i)    At the Effective Time, all Company Stock Options (as
defined in Section 3.2) then outstanding shall be assumed by Parent in
accordance with Section 5.16 below.

               (ii)   At the Effective Time, Parent shall grant to the
CityAuction employees stock options under the Parent's 1998 Stock Option Plan
exercisable for an aggregate of 200,000 shares of Parent Common Stock (the
"EMPLOYEE STOCK OPTIONS"). The exercise price for such option shall be equal to
$53.25 per share. The allocation of such options to employees shall be as set
forth on Exhibit B. The Employee Stock Options shall be subject to the following
         --------- 
vesting provisions:
                                                                       
                      (A)  Employee Stock Options to purchase an aggregate of
100,000 shares shall vest over a four year period as follows: 1/48 per month;
provided, however, that no shares shall be exercisable until the first
anniversary of the optionee's employment with the Company.

                      (B)  Employee Stock Options to purchase an aggregate of
100,000 shares shall also vest over a four year period in accordance with the
vesting provisions set forth in subsection (i) above. Such stock options shall
be subject to acceleration in accordance with the following terms:

                           (1)  In the event that aggregate revenues (i.e.
winning bids multiplied by units won whether or not such sales actually occur)
in auctions completed on the Company's web site (the "CITYAUCTION REVENUE")
during the one year period ending on the first anniversary of this Agreement
exceeds $12.0 million (the "YEAR 1 AUCTION TARGET AMOUNT"), 

                                      -5-
<PAGE>
 
then a total of 37,500 options shall be vested as of the first anniversary date
(which total shall include the options which shall otherwise have vested during
such year) and 37,500 options shall vest ratably on a monthly basis for the
twelve months following the first anniversary date (which total shall include
the options which shall otherwise have vested during such year);

                           (2)  In the event that CityAuction Revenue during the
one year period ending on the first anniversary of this Agreement is between 70%
and 99.9% (the "YEAR 1 ACTUAL PERCENTAGE") of the Year 1 Auction Target Amount,
then the total number of options which shall be vested as of such first
anniversary date shall equal 25,000 options plus the Year 1 Actual Percentage
multiplied by 12,500 options (which total shall include the options which
otherwise shall have vested during such year) and 25,000 options plus the Year 1
Actual Percentage multiplied by 12,500 which shall vest ratably on a monthly
basis for the twelve months following such date (which total shall include the
options which shall otherwise have vested during such year);

                           (3)  In the event that CityAuction Revenue during the
one year period ending on the second anniversary of this Agreement exceeds $30.0
million (the "YEAR 2 AUCTION TARGET AMOUNT"), then all remaining unvested
options shall vest as of such second anniversary date; and

                           (4)  In the event that CityAuction Revenue during the
one year period ending on the second anniversary of the Agreement is between 70%
and 99.9% (the "YEAR 2 ANNUAL PERCENTAGE") of the Year 2 Auction Target Amount,
then the number of remaining unvested options multiplied by the Year 2 Annual
Percentage shall vest as of the second anniversary date, and the remainder shall
vest ratably over the next two years.
 
     In the event that there is a material and fundamental change in the
business condition and structure of the Parent (either through an extraordinary
merger, acquisition or similar event involving the Parent which the parties
agree is beyond the scope of what is reasonably contemplated presently as part
of the Parent's growth strategy) prior to the second anniversary of this
Agreement, the parties agree that they shall discuss in good faith whether the
performance criteria set forth in this Section 2.1 (i)(ii)(B) for the
acceleration of the stock options referenced thereunder should be modified in
recognition of such fundamental change in Parent.

           (j)  Rebele Shares.  Fifty percent (50%) shares of Parent Common
                -------------    
Stock received in the Merger pursuant to Section 2.1(c) by Andrew Rebele shall
be subject to vesting over a two year period following the Closing on a pro rata
monthly basis.

     2.2   EXCHANGE OF CERTIFICATES.
           ------------------------ 

           (a)  Exchange Agent.  Prior to the Effective Time, Parent shall
                --------------                                            
designate a bank or trust company, reasonably acceptable to the Company, to act
as exchange agent (the "EXCHANGE AGENT") in the Merger.

          (b)  Parent to Provide Common Stock.  Promptly after the Effective
               ------------------------------                               
Time, Parent shall deliver to the Exchange Agent in accordance with this Section
2 and the Merger Agreement, the shares of Parent Common Stock issuable pursuant
to Section 2.1 and the Merger Agreement in exchange for outstanding shares of
capital stock of the Company, and cash in an amount sufficient for payment in
lieu of fractional shares pursuant to Section 2.1(f).

          (c)  Exchange Procedures.  As soon as practicable after the Effective
               -------------------                                             
Time, the Surviving Corporation shall cause to be mailed to each holder of
record of a certificate or certificates which immediately prior to the Effective
Time represented outstanding shares of Company Common Stock (the "Certificates")
whose shares are being converted into Parent Common Stock pursuant to Section
2.1 and the Merger Agreement, (i) a letter of transmittal (which shall specify
that delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon delivery of the Certificates to the Exchange Agent and
shall be in such form and have such other provisions as Parent may reasonably
specify) and (ii) instructions for use in effecting the surrender of the
Certificates in exchange for Parent Common Stock.  Upon surrender of a
Certificate for cancellation to the Exchange Agent or to such other agent or
agents as may be appointed by Parent, together with such letter of transmittal,
duly executed, the holder of such Certificate shall be entitled to receive in
exchange therefor the number of shares of Parent Common Stock to which the
holder of Company Common Stock is entitled pursuant to Section 2.1.  The
Certificate so surrendered shall forthwith be canceled.  In the event of a
transfer of ownership of Company Common Stock which is not registered on the
transfer records of the Company, the appropriate number of shares of Parent
Common Stock may be delivered to a transferee if the Certificate representing
such capital stock of the Company is presented to the Exchange Agent and
accompanied by all documents required to evidence and effect such transfer and
to evidence that any applicable stock transfer taxes have been paid.  Until
surrendered as contemplated by this Section 2.2, each Certificate shall be
deemed at any time after the Effective Time to represent the right to receive
upon such surrender the number of shares of Parent Common Stock as provided by
this Section 2 and the provisions of the California Code.

          (d)  No Further Ownership Rights in Capital Stock of the Company.  All
               -----------------------------------------------------------      
Parent Common Stock delivered upon the surrender for exchange of shares of
Company Common Stock in accordance with the terms hereof shall be deemed to have
been delivered in full satisfaction of all rights pertaining to such shares of
Company Common Stock, and following the Effective Time, the Certificates shall
have no further rights to, or ownership in, shares of capital stock of the
Company.  There shall be no further registration of transfers on the stock
transfer books of the Surviving Corporation of the shares of Company Common
Stock which were outstanding immediately prior to the Effective Time.  If, after
the Effective Time, Certificates are presented to the Surviving Corporation for
any reason, they shall be canceled and exchanged as provided in this Section 2.

          (e)  Lost, Stolen or Destroyed Certificates.  In the event any
               --------------------------------------                   
certificates evidencing shares of Company Common Stock shall have been lost,
stolen or destroyed, the 

                                      -7-
<PAGE>
 
Exchange Agent shall make payment in exchange for such lost, stolen or destroyed
certificates, upon the making of an affidavit of that fact by the holder
thereof, such shares of Parent Common Stock and cash for fractional shares, if
any, as may be required pursuant to Section 2.1(f); provided, however, that
Parent may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificates to
deliver a bond in such sum as it may reasonably direct as indemnity against any
claim that may be made against Parent or the Exchange Agent with respect to the
certificates alleged to have been lost, stolen or destroyed.

           (f)  No Liability.  Notwithstanding anything to the contrary in this
                ------------                                                   
Section 2.2, none of the Exchange Agent, the Surviving Corporation or any party
hereto shall be liable to a holder of shares of Company Common Stock for any
amount paid to a public official pursuant to any applicable abandoned property,
escheat or similar law.

           (g)  Dissenting Shares.  The provisions of this Section 2.2 shall
                -----------------
also apply to Dissenting Shares that lose their status as such, except that the
obligations of Parent under this Section 2.2 shall commence on the date of loss
of such status.

corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its organization and has all requisite corporate power
and authority to carry on its business as now being conducted.  The Company is
duly qualified to do business and is in good standing in each jurisdiction in

properties makes such qualification or licensing necessary.  The Company has
delivered to the Parent complete and correct copies of its Articles of
Incorporation and Bylaws.

Stock, are outstanding. All of such outstanding shares have been duly
authorized, validly issued, fully paid and non-assessable and have been issued
in compliance with all applicable federal and state securities laws. The
outstanding shares of capital stock of the Company are not subject to preemptive
rights created by statute, the Articles of Incorporation or Bylaws of the
Company, or any agreement to which the Company is a party or by which it may be
bound. There are no voting agreements or voting trusts with respect to any of
the outstanding shares of capital stock of the Company. The outstanding shares
of capital stock of the Company are held by the persons and in the amounts set

repurchased or redeemed, any shares of the capital stock of the Company or
obligating the Company to grant, extend, accelerate the vesting of, change the
price of, otherwise amend or enter into any such option, warrant, call, right,
commitment or agreement.  The Company's Stock Options and the Warrant have been
issued in compliance with all applicable federal and state securities laws. The
holders of Company Stock Options and the Warrant have been or will be given, or
shall have properly waived, any required notice prior to the Merger.  As a
result of the Merger, Parent will be the record and beneficial owner of all
outstanding capital stock of the Company and, except for stock options granted
pursuant to the Company's Stock Option Plan and the Warrant, rights to acquire
capital stock of the Company.

           ---------------- 

           (a)  Section 3.11(a) of the Company Schedules contains a list of all
"employee pension benefit plans" (as defined in Section 3(2) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")) (sometimes
referred to herein as "PENSION PLANS"), "employee welfare benefit plans" (as
defined in Section 3(l) of ERISA) and all other Benefit Plans maintained or
contributed to by the Company or any person or entity that, together with the
Company, is treated as a single employer under Section 414(b), (c), (m) or (o)
of the Code (a "COMMONLY CONTROLLED ENTITY") for the benefit of any current or
former officers, directors or employees of the Company.  The Company has made
available to Parent true, complete and correct copies of (i) each Benefit Plan
(or, in the case of any unwritten Benefit Plans, descriptions thereof), (ii) the
most recent annual report on Form 5500 required to be filed with the Internal
Revenue Service (the "IRS") with respect to each Benefit Plan (if any such
report was required), (iii) the most recent summary plan description for each
Benefit Plan for which such summary plan description is required and (iv) each
trust agreement and group annuity contract relating to any Benefit Plan.  Each
Benefit Plan has been administered in accordance with its terms, except where
the failure to so administer would not, individually or in the aggregate, have a
Material Adverse Effect on the Company.  The Company and all the Benefit Plans
are all in compliance with applicable provisions of ERISA and the Code, except
for instances of possible noncompliance that would not, individually or in the
aggregate, have a Material Adverse Effect on the Company.

           (b)  Each of the Pension Plans has been the subject of a
determination letter (or its equivalent) from the IRS to the effect that such
Pension Plan is qualified and exempt from United States Federal income taxes
under Sections 401(a) and 501(a), respectively, of the Code, and no such
determination letter (or its equivalent) has been revoked nor has any event
occurred since the date of its most recent determination letter (or its
equivalent) or application therefor that would adversely affect its
qualification or materially increase its costs.

           (c)  Neither the Company nor any Commonly Controlled Entity of the
Company has maintained, contributed to or been obligated to contribute to any
Benefit Plan that is subject to Title IV of ERISA.

           (d)  No officer or employee of the Company will be entitled to any
additional compensation or benefits or any acceleration of the time of payment
or vesting of any compensation or benefits under any Benefit Plan as a result of
the transactions contemplated by this Agreement or any benefits under any
Benefits Plan the value of which will be calculated on the basis of any of the
transactions contemplated by this Agreement.

     3.12  TAXES.  The Company has filed all material tax returns and reports
           -----                                                             
required to be filed by it and all such returns and reports were true and
correct in all material respects.  All taxes that accrue or are payable by the
Company in respect of taxable periods that end on or before the Closing Date and
for any taxable period that begins before the Closing Date and ends thereafter
to the extent such taxes are attributable to the portion of such period ending
on the Closing Date, as 

                                      -14-
<PAGE>
 
determined under the closing of the books method of allocation, have been (or
will have been, on or before the Closing Date) timely paid or an adequate
reserve has been established on the Company Balance Sheet. The most recent
financial statements, dated December 31, 1998, (a true, correct complete copy of
which has been delivered to the Parent by the Company) reflect an adequate
reserve for all taxes payable by the Company for all taxable periods and
portions thereof through the date of such financial statements and no
liabilities for taxes have been incurred since the date of such financial
statements except in the ordinary course of business. No deficiencies for any
taxes have been proposed, asserted or assessed against the Company, and no
requests for waivers of the time to assess any such taxes are pending. As used
in this Agreement, "TAXES" shall include all Federal, state, local and foreign
income, property, sales, excise and other taxes, tariffs or governmental charges
of any nature whatsoever, together with an interest and penalties, whether as
primary obligor or as a result of being a "transferor" (within the meaning of
section 6901 of the Code and any corresponding state and local law) of another
person or a member of an affiliated, consolidated or combined group.

     3.13  NO EXCESS PARACHUTE PAYMENTS.  No amount that could be received
           ----------------------------                                   
(whether in cash or property or the vesting of property) in connection with any
of the transactions contemplated by this Agreement by any employee, officer or
director of the Company who is a "disqualified individual" (as such term is
defined in proposed Treasury Regulation Section 1.280G-1) under any employment,
severance or termination agreement, other compensation arrangement or Benefit
Plan currently in effect would be an "excess parachute payment" (as such term is
defined in Section 280G(b)(1) of the Code).  No such person is entitled to
receive any additional payment from the Company, the Surviving Corporation or
any other person (a "PARACHUTE GROSS-UP PAYMENT") in the event that the excise
tax of Section 4999(a) of the Code is imposed on such person.  The Board of
Directors of the Company has not granted to any officer, director or employee of
the Company any right to receive any Parachute Gross-Up Payment.

     3.14  TITLE TO PROPERTIES.
           ------------------- 

           (a)  The Company has good and marketable title to, or valid leasehold
interests in, all of its properties and assets except for such as are no longer
used or useful in the conduct of its business or as have been disposed of in the
ordinary course of business and except for defects in title, easements,
restrictive covenants and similar encumbrances that individually or in the
aggregate would not have a Material Adverse Effect on the Company.  All such
material assets and properties, other than assets and properties in which the
Company has a leasehold interest, are free and clear of all Liens (other than
Liens for current taxes not yet due and payable), except for Liens that
individually or in the aggregate would not have a Material Adverse Effect on the
Company.

           (b)  The Company has complied in all material respects with the terms
of all leases to which it is a party and under which it is in occupancy, all
such leases are in full force and 

                                      -15-
<PAGE>
 
effect and have been made available to the Parent. The Company enjoys peaceful
and undisturbed possession under all such leases.

     3.15  INTELLECTUAL PROPERTY.
           --------------------- 

           (a)  The Company owns, or has the right to use, sell or license all
intellectual property necessary or required for the conduct of its business as
presently conducted and as presently contemplated (such intellectual property
and the rights thereto are collectively referred to as the "COMPANY IP RIGHTS").

           (b)  Section 3.15 of the Company Schedules sets forth with respect to
the intellectual property of the Company:  (i) for each patent and patent
application, the number, normal expiration date, title and priority information
for each country in which such patent has been issued, or, the application
number, date of filing, title and priority information for each country, (ii)
for each trademark, trade name or service mark, whether or not registered, the
date first used, and, if registered, the application serial number or
registration number, the class of goods covered, the nature of the goods or
services, the countries in which the names or mark is used and the expiration
date for each country in which a trademark has been registered and (iii) for
each copyright for which registration has been sought, whether or not
registered, the date of creation and first publication of the work, the number
and date of registration for each country in which a copyright application has
been registered.

           (c)  The Company has taken all reasonable steps necessary or
appropriate (including, entering into appropriate confidentiality, nondisclosure
agreements with officers, directors, subcontractors, independent contractors,
full-time and part-time employees, licensees and customers) to safeguard and
maintain the secrecy and confidentiality of, and the proprietary rights in, the
Company IP Rights.

           (d)  The execution, delivery and performance of this Agreement and
the consummation of the transactions contemplated hereby will not constitute a
breach of any instrument or agreement governing any Company IP Right (the
"COMPANY IP RIGHTS AGREEMENTS"), will not cause the forfeiture or termination or
give rise to a right of forfeiture or termination of any Company IP Right or
impair the right of the Company, the Surviving Corporation or the Parent to use,
sell or license any Company IP Right or portion thereof.

           (e)  (i)  Neither the manufacture, marketing, license, sale or
intended use of any product or technology currently licensed or sold by the
Company violates any license or agreement between the Company and any third
party or infringes any proprietary right of any other party; and (ii) there is
no pending or, to the knowledge of the Company, threatened claim or litigation
contesting the validity, ownership or right to use, sell, license or dispose of
any Company IP Right or operate the Company's Web service.

Agreement, Parent and Sub represent and warrant to the Company as follows:

     4.1  ORGANIZATION, STANDING AND CORPORATE POWER.  Each of the Parent and
          ------------------------------------------                         
Sub is a corporation duly organized, validly existing and in good standing under
the laws of the jurisdiction of its organization and has all requisite corporate
power and authority to carry on its business as now being conducted.  Each of
the Parent and Sub is duly qualified to do business and is in good standing in
each jurisdiction in which the nature of its business or the ownership, leasing
or operation of its properties makes such qualification or licensing necessary,
other than in such jurisdictions where the failure to be so qualified or
licensed or be in good standing individually or in the aggregate would not have
a Material Adverse Effect on Parent.

     4.2  AUTHORITY/NONCONTRAVENTION.  Each of the Parent and Sub has the
          --------------------------                                     
requisite corporate power and authority to execute and deliver this Agreement
and to consummate the transactions contemplated by this Agreement.  The
execution, delivery and performance of this Agreement by the Company and the
consummation by each of the Parent and Sub of the transactions contemplated by
this Agreement have been duly authorized by all necessary corporate action on
the part of each of the Parent and Sub and no other corporate proceedings on the
part of each of the Parent and Sub are necessary to authorize this Agreement or
to consummate the transactions contemplated hereby.  This Agreement has been
duly executed and delivered by each of the Parent and Sub and constitutes valid
and binding obligations of Parent and Sub, enforceable against the Parent and
Sub in accordance with its terms.  The execution and delivery of this Agreement
do not, and the consummation of the transactions contemplated by this Agreement
and compliance with the provisions of this Agreement will not, conflict with, or
result in any violation of, or default (with or without notice or lapse of time,
or both) under, or give rise to a right of termination, cancellation or
acceleration of any obligation or to loss of a material benefit or require any
consent, approval or authorization under, or result in the creation of any Liens
in or upon any of the properties or assets of the Parent under, any provision of
(a) the Certificate of Incorporation or Bylaws of the Parent or the certificates
of incorporation or bylaws (or similar organizational documents) of any of its
subsidiaries, (b) any loan or credit agreement, bond, debenture, note, mortgage,
indenture, lease or other material contract, commitment, agreement, arrangement,
obligation, undertaking, instrument, permit, concession, franchise or license
applicable to Parent or its properties or assets or (c) subject to the
governmental filings and other matters referred to in the following sentence,
any statute, law, ordinance, rule or regulation or judgment, order or decree, in
each case, applicable to Parent or its properties or assets, other than, in the
case of clauses (b) and (c), any such conflicts, violations, defaults, rights,
or Liens or other occurrences that individually or in the aggregate would not
have a Material Adverse Effect on Parent.  No consent, approval, order or
authorization of, or registration, declaration or filing with, any Governmental
Entity is required by or with respect to the Parent or Sub in connection with
the execution and delivery of this Agreement by Parent or Sub or the
consummation by Parent or Sub of the Merger or the other transactions
contemplated by this Agreement, except for (a) the receipt of a valid exemption
from the registration requirements of the Securities Act, (b) the filing of the
Agreement of Merger with the California Secretary of State and appropriate
documents with the 

                                      -21-
<PAGE>
 
relevant authorities of other states in which Parent is qualified to do business
and (c) such other consents, approvals, orders, authorizations, registrations,
declarations and filings the failure of which to be obtained or made
individually or in the aggregate would not have a Material Adverse Effect on the
Parent or impair the ability of Parent or Sub to perform their obligations under
this Agreement.

     4.3  SEC DOCUMENTS; PARENT FINANCIAL STATEMENTS.  Parent has furnished or
          ------------------------------------------

all material respects with the requirements of the Securities Act and did not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements made therein,
in light of the circumstances in which they were made, not misleading.  The
financial statements of Parent, including the notes thereto, included in the
Registration Statement (the "PARENT FINANCIAL STATEMENTS") comply as to form in
all material respects with applicable accounting requirements and with the
published rules and regulations of the SEC with respect thereto, have been
prepared in accordance with GAAP consistently applied (except as may be

permitted by applicable rules and regulations of the SEC) and fairly present the
consolidated financial position of Parent at the dates thereof and of its
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal, recurring audit adjustments).  There has been
no change in Parent accounting policies except as described in the notes to the
Parent Financial Statements.  Parent has no material obligations other than (i)

               ----------------------                                        
been delivered by Parent.

                                   SECTION 7

                                INDEMNIFICATION

     7.1  GENERAL INDEMNIFICATION.  The Shareholders covenant and agree to
          -----------------------                                         
indemnify, defend, protect and hold harmless Parent and the Surviving
Corporation and their respective officers, directors, employees, shareholders,
assigns, successors and affiliates (individually, an "INDEMNIFIED PARTY" and
collectively, "INDEMNIFIED PARTIES") from, against and in respect of:

          (a)  all liabilities, losses, claims, damages, punitive damages,
courses of actions, lawsuits, administrative proceedings (including informal
proceedings), investigations, audits, demands, assessments, adjustments,
judgments, settlement payments, deficiencies, penalties, fines, interest
(including interest from the date of such damages) and costs and expenses
(including without limitation reasonable attorneys' fees and disbursements of
every kind, nature and description) (collectively, "DAMAGES") suffered,
sustained or incurred by the Indemnified Persons in connection with, resulting
from or arising out of, directly or indirectly:

               (i)    any breach of any representation or warranty of the
Company or the Principal Shareholders set forth in this Agreement or any
certificate, document or instrument delivered by or on behalf of the Company or
the Principal Shareholders in connection herewith;

               (ii)   any nonfulfillment of any covenant or agreement on the
part of the Company or the Principal Shareholders in this Agreement;

               (iii)  the business, operations or assets of the Company prior to
the Closing Date, including without limitation all taxes due and payable prior
to the Closing Date, except as otherwise disclosed in the Company Financial
Statements or the Company Schedules; or

               (iv)   the actions or omissions of the Company's directors,
officers, shareholders, employees or agents prior to the Closing Date; and

                                      -31-
<PAGE>
 
          (b)  any and all Damages incident to any of the foregoing or to the
enforcement of this Section 8.1.

     7.2  LIMITATION AND EXPIRATION.  Notwithstanding the above:
          -------------------------                             

          (a)  There shall be no liability for indemnification under Section 7.1
unless the aggregate amount of Damages exceeds $100,000 (the "INDEMNIFICATION
THRESHOLD"), in which event the liability for indemnification will apply to the
entire aggregate amount of Damages.  The Pledged Shares shall represent the
exclusive means of satisfying any claims under this Section 7 except with
respect to Claims (as defined below) relating to any breach of the
representations and warranties set forth in Section 3.12 (Taxes) and 3.22
(Environmental Matters) or for Claims relating to fraud or willful misconduct.
For purposes of satisfying indemnification obligations pursuant to Section 7.1,
the Pledged Shares shall be valued at the average of the closing price of the
Parent Common Stock as reported on the Nasdaq National Market for the ten
trading days preceding the Closing. Any Damages paid pursuant to this Section 7
shall be paid on a prorated basis by the Shareholders in relation to their
allocable portion of the Pledged Shares; and

          (b)  The indemnification obligations under this Section 7 shall
terminate as follows:

               (i)    with respect to claims or demands (a "CLAIM") relating to
a breach of the representations and warranties set forth in Section 3.12 (Taxes)
and 3.22 (Environmental Matters) or fraud or willful misconduct, upon the later
of the expiration of the applicable statute of limitations period or the final
resolution of any and all such Claims pending as of such date; and

               (ii)   with respect to all other Claims for indemnification under
this Section 7, upon the later of the first anniversary of the Closing Date or
the final resolution of any such claims pending as of the first anniversary.

          The term "INDEMNIFICATION DEADLINE DATE" refers to the expiration date
of the applicable statute of limitations period with respect to Claims under
clause (i) above and the first anniversary with respect to claims under clause
(ii) above.  The term "PENDING CLAIMS" refers to the pending claims described in
clauses (i) and (ii) above.  From and after the applicable Indemnification
Deadline Date, the indemnification obligations under this Section 7 shall
survive only to the extent of Pending Claims.
 
     7.3  INDEMNIFICATION PROCEDURES.  All Claims for indemnification under this
          --------------------------                                            
Section 7 shall be asserted and resolved as follows:

          (a)  In the event the Indemnified Party has a Claim hereunder which
does not involve a Claim being asserted against or sought to be collected by a
third party, the Indemnified Party shall with reasonable promptness send a Claim
Notice (as defined in Section 7.3(c) below) 

                                      -32-
<PAGE>
 
with respect to such Claim to the Shareholder Representative (as defined in
Section 7.4 below). If the Shareholder Representative does not notify the
Indemnified Party within 45 days from the date of receipt of such Claim Notice
that the Shareholders dispute such Claim, the amount of such Claim shall be
conclusively deemed a liability of the Shareholders hereunder. In case the
Shareholder Representative shall object in writing to any Claim made in
accordance with this Section 7.3(a), the Indemnified Party shall have fifteen
(15) days to respond in a written statement to the objection of the Shareholder
Representative. If after such fifteen (15) day period there remains a dispute as
to any Claims, the parties shall attempt in good faith for sixty (60) days to
agree upon the rights of the respective parties with respect to each of such
Claims. If the parties should so agree, a memorandum setting forth such
agreement shall be prepared and signed by both parties. If no such agreement can
be reached after good faith negotiation, either party may demand arbitration of
the matter unless the amount of the damage or loss is at issue in pending
litigation with a third party, in which event arbitration shall not be commenced
until such amount is ascertained or both parties agree to arbitration; and in
either such event the matter shall be settled by arbitration conducted by three
arbitrators. Parent and the Shareholders' Representative shall each select one
arbitrator, and the two arbitrators so selected shall select a third arbitrator,
each of which arbitrators shall be independent and have at least ten years
relevant experience. The arbitrators shall set a limited time period and
establish procedures designed to reduce the cost and time for discovery while
allowing the parties an opportunity, adequate in the sole judgment of the
arbitrators, to discover relevant information from the opposing parties about
the subject matter of the dispute. The arbitrators shall rule upon motions to
compel or limit discovery and shall have the authority to impose sanctions,
including attorneys fees and costs, to the extent as a court of competent law or
equity, should the arbitrators determine that discovery was sought without
substantial justification or that discovery was refused or objected to without
substantial justification. The decision of a majority of the three arbitrators
as to the validity and amount of any Claim in such Claim Notice shall be binding
and conclusive upon the parties to this Agreement. Such decision shall be
written and shall be supported by written findings of fact and conclusions which
shall set forth the award, judgment, decree or order awarded by the arbitrators.

          (b)  Judgment upon any award rendered by the arbitrators may be
entered in any court having jurisdiction. Any such arbitration shall be held in
Los Angeles County, California under the rules then in effect of the American
Arbitration Association. For purposes of this Section 7.3, in any arbitration
hereunder in which any claim or the amount thereof stated in the Claim Notice is
at issue, the Indemnified Party shall be deemed to be the Non-Prevailing Party
in the event that the arbitrators award such Indemnified Party less than the sum
of one-half (1/2) of the disputed amount plus any amounts not in dispute;
otherwise, the Indemnifying Party shall be deemed to be the Non-Prevailing
Party. The Non-Prevailing Party to an arbitration shall pay its own expenses,
the fees of each arbitrator, the administrative costs of the arbitration, and
the expenses, including without limitation, reasonable attorneys' fees and
costs, incurred by the other party to the arbitration.

          (c)  In the event that any Claim for which the Shareholders would be
liable to an Indemnified Party hereunder is asserted against an Indemnified
Party by a third party, the Indemnified Party shall with reasonable promptness
notify the Shareholder Representative of such 

                                      -33-
<PAGE>
 
Claim, including a copy of the Claim made if the Claim was made in writing,
specifying the nature of such claim and the amount or the estimated amount
thereof to the extent then feasible (which estimate shall not be conclusive of
the final amount of such Claim) (the "CLAIM NOTICE"). The Shareholder
Representative shall have 30 days from the receipt of the Claim Notice (the
"NOTICE PERIOD") to notify the Indemnified Party (i) whether or not the
Shareholder Representative disputes the Shareholders' liability to the
Indemnified Party hereunder with respect to such Claim and (ii) if the
Shareholder Representative does not dispute such liability, whether or not the
Shareholder Representative desires, at the sole cost and expense of the
Shareholders, to defend against such Claim, provided that the Shareholder is
hereby authorized (but not obligated) prior to and during the Notice Period to
file any motion, answer or other pleading and to take any other action which the
Shareholder Representative shall deem necessary or appropriate to protect the
Shareholders' interests. In the event that the Shareholder Representative
notifies the Indemnified Party within the Notice Period that the Shareholder
Representative does not dispute the Shareholders' obligation to indemnify
hereunder and desires to defend the Indemnified Party against such Claim and
except as hereinafter provided, the Shareholder Representative shall have the
right to defend by appropriate proceedings, which proceedings shall be
diligently settled or prosecuted by the Shareholder Representative to a final
conclusion; provided that, unless the Indemnified Party otherwise agrees in 
            --------                             
writing, the Shareholder Representative may not settle any matter (in whole or
in part) unless such settlement includes a complete and unconditional release of
the Indemnified Party. If the Indemnified Party desires to participate in, but
not control, any such defense or settlement the Indemnified Party may do so at
the Indemnified Party's sole cost and expense. If the Shareholder Representative
elects not to defend the Indemnified Party against such Claim, whether by
failure of the Shareholder Representative to give the Indemnified Party timely
notice as provided above or otherwise, then the Indemnified Party, without
waiving any rights against the Shareholders, may settle or defend against any
such Claim in the Indemnified Party's sole discretion and the Indemnified Party
shall be entitled to recover from the Shareholders the amount of any settlement
or judgment and, on an ongoing basis, all indemnifiable costs and expenses of
the Indemnified Party with respect thereto, including interest from the date
such costs and expenses were incurred.

          (d)  Notwithstanding Section 7.4(b) above, the Indemnified Party shall
have the right to control or assume (as the case may be) the defense of any
Claim and the amount of any judgment or settlement and the reasonable costs and
expenses of defense shall be included as part of the indemnification obligations
of the Shareholders hereunder if any Claim seeks material prospective relief
which, in the reasonable opinion of the Indemnified Party, could have a material
adverse effect on the assets, liabilities, financial condition, results of
operations or business prospects of Parent and the Indemnified Party shall have
given the Shareholder Representative written notice of the same.  If the
Indemnified Party should elect to exercise such right, the Shareholder
Representative shall have the right to participate in, but not control, the
defense of such claim or demand at the sole cost and expense of the
Shareholders.  Notwithstanding the foregoing, the Indemnified Party shall not
settle any Claim without the written consent of the Shareholder Representative,
which consent shall not be unreasonably withheld.

                                      -34-
<PAGE>
 
          (e)  Nothing herein shall be deemed to prevent the Indemnified Party
from making a Claim, and an Indemnified Party may make a Claim hereunder, for
potential or contingent claims or demands provided the Claim Notice sets forth
the specific basis for any such potential or contingent claim or demand to the
extent then feasible and the Indemnified Party has reasonable grounds to believe
that such a claim or demand may be made.

          (f)  The Indemnified Party's failure to give reasonably prompt notice
to the Shareholder Representative of any actual, threatened or possible claim or
demand which may give rise to a right of indemnification hereunder shall not
relieve the Shareholders of any liability which the Shareholders may have to the
Indemnified Party unless the failure to give such notice materially and
adversely prejudiced the Shareholders.

          (g)  The parties will make appropriate adjustments for any tax
benefits, tax detriments or insurance proceeds in determining the amount of any
indemnification obligation under Section 7, provided that the Shareholder
                                            --------                     
Representative shall not be obligated to seek any payment pursuant to the terms
of any insurance policy.

          (h)  The Pledged Shares shall be available to satisfy the
indemnification obligations of the Shareholder pursuant to this Section 7
through the first anniversary of this Agreement; provided however, that in the
event that any Pending Claims are outstanding as of such date, an amount of
Pledged Shares equal to 125% of such Pending Claims shall remain available to
satisfy such Pending Claims until the resolution of such Pending Claims (the
"PLEDGED SHARES EXPIRATION DATE").  As soon as reasonably practicable following
the Pledged Shares Expiration Date, Parent shall distribute all Pledged Shares
not required to satisfy indemnification obligations under this Section 7 to the
Shareholders.  The Pledged Shares shall bear a restrictive legend preventing
their transfer pending expiration of such indemnification obligations in
substantially the form set forth below:

     "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN PLEDGED AS COLLATERAL
     PURSUANT TO THAT CERTAIN AGREEMENT AND PLAN OF REORGANIZATION DATED JANUARY
     8, 1999 BY AND AMONG TICKETMASTER ONLINE-CITYSEARCH, INC., NERO ACQUISITION
     CORPORATION AND CITYAUCTION.   PRIOR TO THE EXPIRATION OF THE PLEDGE AS SET
     FORTH IN SUCH AGREEMENT, SUCH SHARES MAY NOT BE OFFERED, SOLD, EXCHANGED,
     TRANSFERRED OR OTHERWISE DISPOSED OF."

Within three (3) business days following the Indemnification Deadline Date,
Parent shall use its reasonable commercial efforts to remove any stop transfer
orders made to the Transfer Agent, shall authorize the Transfer Agent to remove
the restrictive legend relating to the obligations of this Section 7 and shall
release the number of Pledged Shares equal to (i) the total number of Pledged
Shares minus (ii) the number of Pledged Shares having a Value (as defined below)
equal to the amount of all indemnification obligations of the Shareholders
through the Indemnification Deadline Date plus any amount necessary to satisfy
any Pending Claims as of the Indemnification Deadline Date.  Upon final
resolution of all Pending Claims, Parent shall remove any stop transfer 

                                      -35-
<PAGE>
 
orders made to the Transfer Agent, shall authorize its Transfer Agent to remove
the restrictive legend relating to the indemnification obligations of this
Section 7 and shall release the number of Pledged Shares equal to (i) the number
of Pledged Shares that were retained by Parent on the Indemnification Deadline
Date pursuant to the foregoing sentence minus (ii) the number of Pledged Shares
having a Value equal to the amount of the indemnification obligations of the
Shareholders under this Section 7 as determined upon the resolution of the
Pending Claims. For purposes of this Agreement, the term "Value" per Pledged
Share shall mean the lower of the per share price of Parent Company Common Stock
as reported on the Nasdaq National Market on (i) the Effective Date or (ii) date
of delivery of a Claim.


     7.4  SHAREHOLDERS' REPRESENTATIVE.
          ---------------------------- 

          (a)  Upon the closing of the Merger, Andrew Rebele shall be
constituted and appointed as agent and attorney-in-fact (the "SHAREHOLDERS'
REPRESENTATIVE") for and on behalf of each of the Shareholders to give and
receive notices and communications, to authorize delivery to Parent of Pledged
Shares in satisfaction of Claims, to object to such deliveries, to agree to,
negotiate, enter into settlements and compromises of, and demand arbitration and
comply with orders of courts and awards of arbitrators with respect to Claims,
and to take all actions necessary or appropriate in the judgment of the
Shareholders' Representative for the accomplishment of the foregoing. Such
agency may be changed (whether pursuant to vacancy, removal or resignation) by
the vote of a majority of the Shareholders from time to time upon not less than
thirty (30) days prior written notice to Parent. No bond shall be required of
the Shareholders' Representative, and the Shareholders' Representative shall
receive no compensation for its services, except for payment by the Shareholders
of expenses, including fees of counsel, reasonably incurred by the Shareholders'
Representative in connection with the performance of its duties hereunder.

          (b)  The Shareholders' Representative shall not be liable for any act
done or omitted hereunder as Shareholders' Representative while acting in good
faith, and any act done or omitted pursuant to the advice of counsel shall be
conclusive evidence of such good faith. The Shareholders shall severally
indemnify the Shareholders' Representative and hold such agent harmless against
any loss, liability or expense incurred without bad faith on the part of the
Shareholders' Representative and arising out of or in connection with the
acceptance or administration of the Shareholders' Representative's duties
hereunder.

          (c)  A decision, act, consent or instruction of the Shareholders'
Representative shall constitute a decision of all Shareholders and shall be
final, binding and conclusive upon each Shareholder, and Parent may rely upon
any decision, act, consent or instruction of the Shareholders' Representative
taken in such manner as being the decision, act, consent or instruction of each
and every Shareholder. The Parent is hereby relieved from any liability to any
person for any acts done by them in accordance with such decision, act, consent
or instruction of the Shareholders' Representative.

     7.5  SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS. All
          -----------------------------------------------------     
representations, warranties and covenants made by the Company and the Principal
Shareholders in or pursuant to this Agreement or in any document delivered
pursuant hereto will survive the Closing and will remain in effect until, and
will expire upon the Indemnification Deadline Date, provided, however, that the
indemnification obligations with respect to any Pending Claim (and the related
representations, warranties and covenants) will survive until the final
resolution of such Pending Claim.


                                   SECTION 8

                       TERMINATION, AMENDMENT AND WAIVER

     8.1  TERMINATION.  This Agreement may be terminated and the Merger
          -----------                                                  
abandoned at any time prior to the Effective Time, whether before or after
approval of the Merger by the shareholders of the Company:

          (a)  by mutual written consent of the Company and Parent;

          (b)  by Parent or the Company if the Closing has not occurred by March
31, 1998: provided however, that the right to terminate this Agreement under
this Section 8.1(b) shall not be available to any party whose action or failure
to act has been the principal cause of the failure of the Merger to occur on or
before such date and such action or failure to act constitutes a material breach
of this Agreement;

          (c)  by Parent or the Company if there shall be a final nonappealable
order of a federal or state court in effect preventing consummation of the
Merger; or there shall be any action taken, or any statute, rule, regulation or
order enacted, promulgated or issued or deemed applicable to the Merger by any
Governmental Entity which would make the consummation of the Merger illegal;

          (d)  by Parent if there shall be any action taken, or any statute,
rule, regulation or order enacted, promulgated or issued or deemed applicable to
the Merger by any Governmental Entity, which would: (i) prohibit Parent's or the
Company's ownership or operation of all or a portion of the business of the
Company or (ii) compel Parent or the Company to dispose of or hold separate all
or a portion of the business or assets of the Company or Parent as a result of
the Merger;

          (e)  by Parent if it is not in breach of its obligations under this
Agreement and there has been a breach of any representation, warranty, covenant
or agreement contained in this Agreement on the part of the Company or the
Principal Shareholders and such breach has not been cured within five (5)
business days after written notice to the Company and the Principal Shareholder
(provided that no cure period shall be required for a breach which by its nature
cannot be cured); or

                                      -37-

this Agreement and there has been a breach of any representation, warranty,
covenant or agreement contained in this Agreement on the part of Parent or Sub
and such breach has not been cured within five (5) business days after written
notice to Parent (provided that no cure period shall be required for a breach
which by its nature cannot be cured).

     Where action is taken to terminate this Agreement pursuant to this Section
8.1, it shall be sufficient for such action to be authorized by the Board of
Directors (as applicable) of the party taking such action.

     8.2  EFFECT OF TERMINATION.  In the event of termination of this Agreement
          ---------------------                                                
as provided in Section 8.1, this Agreement shall forthwith become void and there
shall be no liability or obligation on the part of Parent, Sub, the Company or
the Principal Shareholders, or their respective officers, directors or
shareholders, provided that each party shall remain liable for any breaches of
this Agreement prior to its termination; and provided further that, the
provisions of Sections 5.5, 5.6, 8 and 9 of this Agreement shall remain in full
force and effect and survive any termination of this Agreement.

     8.3  AMENDMENT.  This Agreement may be amended by the parties hereto at any
          ---------                                                             
time prior to the Closing by execution of an instrument in writing signed on
behalf of each of the parties hereto, provided however that no amendment shall
be made which by law requires the further approval of the shareholders of the
Company without obtaining such approval.

     8.4  EXTENSION; WAIVER.  At any time prior to the Effective Time, Parent
          -----------------                                                  
and Sub, on the one hand, and the Company, on the other, may, to the extent
legally allowed, (i) extend the time for the performance of any of the
obligations 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 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.

                              AGREEMENT OF MERGER


     THIS AGREEMENT OF MERGER (the "Merger Agreement") is made and entered into

     NOW THEREFORE, in consideration of the premises and mutual covenants and

time of such filing is referred to as the "Effective Time."

        (c) Surviving Corporation. At the Effective Time, Sub shall be merged
            ---------------------
into the Company and the separate corporate existence of Sub shall thereupon
cease. The Company shall be the surviving corporation in the Merger and shall

sale, assignments, assurances or any other actions or things are necessary or
desirable (i) to vest, perfect or confirm of record or otherwise in the

assets of either Constituent Corporation acquired or to be acquired by the
Surviving Corporation as a result of, or in connection with, the Merger or (ii)
to otherwise carry out the purposes of this Merger Agreement, each Constituent
Corporation and its officers and directors shall be deemed to have granted to
the Surviving Corporation an irrevocable power of attorney to execute and
deliver all such deeds, bills of sale, assignments and assurances and to take
and do all such other actions and things as may be necessary or desirable to
vest, perfect or confirm any and all right, title and interest in, to and under

of the Surviving Corporation are fully authorized in the name of each
Constituent Corporation or otherwise to take any and all such actions.

                                  ARTICLE III

                     ARTICLES OF INCORPORATION AND BYLAWS
                         OF THE SURVIVING CORPORATION

  3.1   Articles of Incorporation of the Surviving Corporation. The Articles of
        ------------------------------------------------------

        -------------------------------
immediately prior to the Effective Time shall be the Bylaws of the Surviving

                                  ARTICLE IV

               EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE
              CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

  4.1   Effect on Capital Stock. As of the Effective Time, by virtue of the
        -----------------------
Merger and without any action on the part of the holder of any shares of capital
stock of the Company:

        (a) Capital Stock of Sub. Each issued and outstanding share of capital
            --------------------
stock of Sub shall continue to be issued and outstanding and shall be converted
into one share of validly issued, fully paid and non-assessable Common Stock of
the Surviving Corporation. Each stock certificate of Sub evidencing ownership of
any such shares shall continue to evidence ownership of such shares of capital
stock of the Surviving Corporation.

        (b) Cancellation of Certain Shares of Capital Stock of the Company. All
            --------------------------------------------------------------
shares of Common Stock and Preferred Stock of the Company that are owned
directly or indirectly by the Company shall be canceled and no stock of Parent
or other consideration shall be delivered in exchange therefor.

        (c) Conversion of Capital Stock of the Company. Subject to Sections
            ------------------------------------------
4.1(d), (e), (f) and (g) below, each issued and outstanding share of Common
Stock of Company (other than shares to be canceled pursuant to Section 4.1(b)
hereof and the Reorganization Agreement) that is issued and outstanding
immediately prior to the Effective Time shall automatically be canceled and
extinguished and converted, without any action on the part of the holder
thereof, into the right to receive 0.279971340 shares of Class B Common Stock,
$.01 par value, of Parent ("Parent Common Stock"). Each issued and outstanding
share of Preferred Stock of the Company that is issued and outstanding
immediately prior to the Effective Time shall automatically be canceled and
exstinguished and converted, without any action on the part of the holder
thereof, into the right to receive the number of shares of Parent Common Stock
equal to the number of shares of Company Preferred Stock held multiplied by
0.013520482 plus the number of shares of Company Preferred

                                      -3-
<PAGE>
 
Stock held multiplied by 0.279971340. All such shares of Company capital stock,
when so converted, shall no longer be outstanding and shall automatically be
canceled and retired and shall cease to exist, and each holder of a certificate
representing any such shares shall cease to have any rights with respect
thereto, except the right to receive the shares of Parent Class B Common Stock
to be issued or paid in consideration therefor upon the surrender of such
certificate in accordance with Section 4.2 hereof and the Reorganization
Agreement. The ratios pursuant to which each share of Company Common Stock and
each share of Company Preferred Stock will be exchanged for shares of Parent
Class B Common Stock, determined in accordance with the foregoing provisions, is
referred to as the "Exchange Ratios."

        (d) Dissenters' Rights. Any shares of Company Common or Preferred Stock
            ------------------
held by a holder who has properly exercised dissenters' rights for such shares
in accordance with the California Code and who, as of the Effective Time, has
not effectively withdrawn or lost such dissenters' rights ("Dissenting Shares")
shall not be converted into Parent Common Stock but shall be converted into the
right to receive such consideration as may be determined to be due with respect
to such Dissenting Shares pursuant to the California Code. The Company shall
give Parent prompt notice of any demand received by the Company to require the
Company to purchase shares of Company Common or Preferred Stock, and Parent
shall have the right to participate in all negotiations and proceedings with
respect to such demand. The Company agrees that, except with the prior written
consent of Parent, or as required under the California Code, it will not
voluntarily make any payment with respect to, or settle or offer to settle, any
such purchase demand. Each holder of Dissenting Shares (a "Dissenting
Shareholder") who, pursuant to the provisions of the California Code, becomes
entitled to payment of the value of shares of Company Common Stock shall receive
payment therefor (but only after the value therefor shall have been agreed upon
or finally determined pursuant to such provisions). In the event of legal
obligation, after the Effective Time, to deliver shares of Parent Common Stock
to any holder of shares of Company Common or Preferred Stock who shall have
failed to make an effective purchase demand or shall have lost its status as a
Dissenting Shareholder, Parent shall issue and deliver, upon surrender by such
Dissenting Shareholder of such holder's certificate or certificates representing
shares of capital stock of the Company, the shares of Parent Common Stock to
which such Dissenting Shareholder is then entitled under this Section 2.1 and
the Reorganization Agreement.

        (e) Fractional Shares. No fractional shares of Parent Common Stock shall
            -----------------
be issued, but in lieu thereof each holder of shares of Company Preferred Stock
or Common Stock who would otherwise be entitled to receive a fraction of a share
of Parent Common Stock shall receive from Parent an amount of cash equal to the
per share market value of Parent Common Stock (based on the last sales price of
Parent Common Stock as reported on the Nasdaq National Market on the date of
confirmation of the filing of the Merger Agreement, together with the required
officers' certificates, in accordance with the Code on the closing date of the
Merger) multiplied by the fraction of a share of Parent Common Stock to which
such holder would otherwise be entitled. The fractional share interests of each
shareholder of the Company shall be aggregated, so that no Company shareholder
shall receive cash in an amount greater than the value of one full share of
Parent Common Stock.

                                      -4-
<PAGE>
 
        (f) Pledged Shares. Upon the Closing, 75,000 shares (of Parent Common
            --------------
Stock) of the purchase price shall be held by Parent and shall be available for
satisfaction of indemnification claims made by Parent under Section 7 of the
Reorganization Agreement and such shares shall bear a restrictive legend to such
effect.

        (g) Stock Options. At the Effective Time, all Company Stock Options then
            -------------
outstanding shall be assumed by Parent in accordance with Section 5.16 of the
Reorganization Agreement.

  4.2   Exchange of Certificates.
        ------------------------

        (a) Exchange Agent. Prior to the Effective Time, Parent shall designate
            --------------
a bank or trust company, reasonably acceptable to the Company, to act as
exchange agent (the "Exchange Agent") in the Merger.

        (b) Parent to Provide Common Stock. Promptly after the Effective Time,
            ------------------------------
Parent shall deliver to the Exchange Agent in accordance with Section 4 hereof
and the Reorganization Agreement, the shares of Parent Common Stock issuable
pursuant to Section 4.1 hereof and the Reorganization Agreement in exchange for
outstanding shares of capital stock of the Company, and cash in an amount
sufficient for payment in lieu of fractional shares pursuant to Section 4.1(f)
above.

        (c) Exchange Procedures. As soon as practicable after the Effective
            -------------------  
Time, the Survivin g Corporation shall cause to be mailed to each holder of
record of a certificate or certificates which immediately prior to the Effective
Time represented outstanding shares of Company Preferred Stock or Common Stock
(the "Certificates") whose shares are being converted into Parent Common Stock
pursuant to Section 4.1 hereof and the Reorganization Agreement, (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and shall be in such form and have such other
provisions as Parent may reasonably specify) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for Parent Common Stock.
Upon surrender of a Certificate for cancellation to the Exchange Agent or to
such other agent or agents as may be appointed by Parent, together with such
letter of transmittal, duly executed, the holder of such Certificate shall be
entitled to receive in exchange therefor the number of shares of Parent Common
Stock to which the holder of Company Preferred Stock or Common Stock is entitled
pursuant to Section 4.1 hereof and the Reorganization Agreement. The Certificate
so surrendered shall forthwith be canceled. In the event of a transfer of
ownership of Company Preferred Stock or Common Stock which is not registered on
the transfer records of the Company, the appropriate number of shares of Parent
Common Stock may be delivered to a transferee if the Certificate representing
such capital stock of the Company is presented to the Exchange Agent and
accompanied by all documents required to evidence and effect such transfer and
to evidence that any applicable stock transfer taxes have been paid. Until
surrendered as contemplated by this Section 4.2, each Certificate shall be
deemed at any time after the Effective Time to represent the right to receive
upon such surrender the

                                      -5-
<PAGE>
 
number of shares of Parent Common Stock as provided by this Section 2 and the
provisions of the California Code.

        (d) No Further Ownership Rights in Capital Stock of the Company. All
            -----------------------------------------------------------
Parent Common Stock delivered upon the surrender for exchange of shares of
Company Preferred Stock or Common Stock in accordance with the terms hereof
shall be deemed to have been delivered in full satisfaction of all rights
pertaining to such shares of Company Preferred Stock or Common Stock, and
following the Effective Time, the Certificates shall have no further rights to,
or ownership in, shares of capital stock of the Company. There shall be no
further registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of Company Preferred Stock or Common Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Section 4.

        (e) Lost, Stolen or Destroyed Certificates. In the event any
            --------------------------------------
certificates evidencing shares of Company Preferred Stock or Common Stock shall
have been lost, stolen or destroyed, the Exchange Agent shall make payment in
exchange for such lost, stolen or destroyed certificates, upon the making of an
affidavit of that fact by the holder thereof, such shares of Parent Common Stock
and cash for fractional shares, if any, as may be required pursuant to Section
4.1(f) hereof and the Reorganization Agreement; provided, however, that Parent
may, in its discretion and as a condition precedent to the issuance thereof,
require the owner of such lost, stolen or destroyed certificates to deliver a
bond in such sum as it may reasonably direct as indemnity against any claim that
may be made against Parent or the Exchange Agent with respect to the
certificates alleged to have been lost, stolen or destroyed.

        (f) No Liability. Notwithstanding anything to the contrary in this
            ------------
Section 4.2, none of the Exchange Agent, the Surviving Corporation or any party
hereto shall be liable to a holder of shares of Company Preferred or Common
Stock for any amount paid to a public official pursuant to any applicable
abandoned property, escheat or similar law.

        (g) Dissenting Shares. The provisions of this Section 4.2 shall also
            -----------------
apply to Dissenting Shares that lose their status as such, except that the
obligations of Parent under this Section 4.2 shall commence on the date of loss
of such status.

                           NON-COMPETITION AGREEMENT


     THIS NON-COMPETITION AGREEMENT (the "Agreement") is entered into as of
___________, 1999 by and among Ticketmaster Online-CitySearch, Inc., a Delaware
corporation ("Parent"), CityAuction, Inc., a California corporation (the
"Company") and ________________________________ (the "Manager").

                                   Background

     A.  Parent, Caligula Acquisition Corporation ("Sub") and the Company have
entered into an Agreement and Plan of Reorganization dated as of January __,
1999 (the "Reorganization Agreement"), which provides for the merger (the
"Merger") of Sub with and into the Company.  Capitalized terms not otherwise
defined in this Agreement have the meanings defined for them in the
Reorganization Agreement.

     B.  As a condition to the Merger, to preserve the value of the business
being acquired by Parent, the Reorganization Agreement contemplates, among other
things, that the Manager enter into this Agreement effective upon the Effective
Time of the Merger.

     NOW THEREFORE, in consideration of the mutual promises made in this
Agreement, Parent, the Company and the Manager agree as follows:

     1.  Covenant Not to Compete or Solicit.
         ----------------------------------
         (a) For two (2) years after the termination of Manager's employment
with Parent, the Company or any sudsidiary thereof (the "Non-Compete Period"),
the Manager shall not directly or indirectly for himself/herself or on behalf of
or in conjunction with any other person, company, partnership, corporation,
business, group or other entity, without the prior written consent of Parent,
engage anywhere in the world in (whether as an employee, consultant, proprietor,
partner, director or otherwise), or have any ownership interest in (except for
ownership of one percent (1%) or less of the outstanding securities of an entity
whose securities are listed on a national securities exchange), or participate
in the financing, operation, management or control of, any firm, corporation or
business or any business unit of any firm or corporation in any business selling
products or services in direct competition with the Parent's or the Company's
business, including the on-line ticketing, city guide, on-line auctions, and/or
on-line classifieds businesses.

         During the Non-Compete Period, the Manager shall not, directly or
indirectly, without the prior written consent of Parent, (i) solicit, encourage,
hire or take any other action which is intended to induce any employee of the
Company or Parent or any subsidiary thereof to terminate his or her 
<PAGE>
 
employment with the Company or Parent or any subsidiary thereof (as the case may
be), or (ii) interfere in any manner with the contractual or employment
relationship between the Company and any employee of the Company or Parent and
any employee of Parent or any subsidiary of the Company or Parent and any
employee of any such subsidiary.

        (b) The covenants contained in the preceding paragraphs shall be
construed as a series of separate convents, one of each county, city and state
of any geographic area where any business is presently carried on by Parent or
the Company. Except for geographic coverage, each such separate covenant shall
be identical in terms to the covenant contained in the preceding paragraphs. If,
in any judicial proceeding, a court refuses to enforce any of such separate
covenants (or any part thereof), then such unenforceable covenant (or such part)
shall be eliminated from this Agreement to the extent necessary to permit the
remaining separate covenants (or portions thereof) to be enforced. In the event
that the provisions of this Section 1 are deemed to exceed the time, geographic
or scope limitations permitted by applicable law, then such provisions shall be
reformed to the maximum time, geographic or scope limitations, as the case may
be, permitted by applicable laws.

        (c) The Manager acknowledges that the Manager's covenant not to compete
or solicit contained in this Section 1 is a condition precedent to the Merger to
preserve the value of the business being purchased by Parent pursuant to the
Merger. The Manager further acknowledges that breach of this Section 1 would
cause irreparable injury to Parent and the Company and agrees that in the event
of such breach, Parent and the Company shall each be entitled to injunctive
relief without the necessity of proving actual damages.

  2.    Miscellaneous.
        -------------

        (a) Severability. If any portion of this Agreement is held by a court of
            ------------
competent jurisdiction to conflict with any federal, state or local law, such
portion of this Agreement shall be of no force or effect and this Agreement
shall otherwise remain in full force and effect and be construed as if such
portion had not been included in this Agreement.

        (b) No Assignment. The Manager shall not assign this Agreement or any
            -------------
rights or obligations under this Agreement without the prior written consent of
Parent.

        (c) Notice. Any notice or other communication required or permitted
            ------
under this Agreement shall be made in writing and delivered personally to the
other parties or sent by certified or registered mail, return receipt requested
and postage prepaid to the addresses set forth on the signature page hereto or
such other address as any such party shall have furnished to the other parties
in writing in accordance with this Section 2(c).

        (d) Entire Agreement. This Agreement contains the entire agreement and
            ----------------
understanding of the parties and supersedes all prior discussions, agreements
and understandings relating to the subject matter of this Agreement. This
Agreement may not be changed or modified, except by an agreement in writing
executed by Parent and the Manager.

        (e) Effectiveness: Term. This Agreement shall become effective upon the
            -------------------
Effective Date and shall continue in full force and effect for two (2) years
from its effectiveness.

                                      -2-
<PAGE>
 
      (f) Other. The waiver of a breach of any term or provision of this
          -----
Agreement shall not operate as or be construed to be a waiver of any other
previous or subsequent breach of this Agreement. This Agreement shall be
governed by the laws of the State of California. All captions and section
headings used in this Agreement are for convenient reference only and do not
form a part of this Agreement. This Agreement may be executed in counterparts,
and each counterpart shall have the same force and effect as an original and
shall constitute an effective, binding agreement on the part of each of the
undersigned.

                                      -3-

                                   ---------


                      INVESTMENT REPRESENTATION AGREEMENT


     The undersigned is aware that pursuant to an Agreement and Plan of
Reorganization, dated as of January 8, 1999, (the "Reorganization Agreement"),
entered into by and among Ticketmaster Online - CitySearch, Inc., a Delaware
corporation ("Parent"), Nero Acquisition Corporation, a California corporation
and a wholly owned subsidiary of Parent ("Sub"), CityAuction, Inc., a California
corporation (the "Company"), and Andrew Rebele and Monica Lee, individuals and
principal shareholders of the Company (each, a "Principal Shareholder"), Sub
will merge (the "Merger") with and into the Company and all shares of Company
Capital Stock will be exchanged for shares of Parent Common Stock set forth in
the Reorganization Agreement (the "Merger Consideration").  Unless otherwise
indicated, capitalized terms not defined herein have the meanings set forth in
the Reorganization Agreement.

     The undersigned understands that the execution of this Certificate is a
condition precedent to Parent and Sub's obligation to consummate the Merger and
to the receipt of the shares of Parent Common Stock in connection with the
Merger (pursuant to the terms and conditions of the Reorganization Agreement).

     The undersigned hereby represents and warrants as follows:

          1.   The Parent Common Stock issued to the undersigned will be
acquired for investment for the undersigned's own account, not as a nominee or
agent, and not with a view to the sale or distribution of any part thereof in
violation of the Securities Act of 1933, as amended (the "1933 Act"), and the
undersigned has no present intention of selling, granting any participation in,
or otherwise distributing the same.  The undersigned represents that the entire
legal and beneficial interest of the Parent Common Stock will be held for the
undersigned's account only, and neither in whole or in part for any other person
other than a wholly owned subsidiary of the undersigned.  By executing this
Agreement, the undersigned further represents that the undersigned has no
present contract, undertaking, agreement or arrangement with any person to sell,
transfer, or grant participation to such person or to any third person, with
respect to any of the Parent Common Stock.

          2.   The undersigned represents that (without limiting or affecting
the representations and warranties of Parent or Sub under the Reorganization
Agreement) it: (i) has such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of the undersigned's
prospective investment in the shares of Parent Common Stock; (ii) has received
copies of Parent's Registration Statement on Form S-1 dated December 2, 1998;
(iii) has received all the information it has requested from the Parent and the
Company it considers necessary or appropriate for deciding whether to accept the
Parent Common Stock; (iv) has the ability to bear the economic risks of the
undersigned's prospective investment; and (v) is able, without materially
impairing its financial 
<PAGE>
 
condition, to hold the Parent Common Stock for an indefinite period of time and
to suffer complete loss on its investment.

          3.   Each certificate representing Parent Company Stock issued
pursuant hereto to the undersigned and any shares issued or issuable in respect
of any such Parent Common Stock upon any stock split, stock dividend,
recapitalization, or similar event, shall be stamped or otherwise imprinted with
legends in the following form (in addition to any legend required under
applicable state securities laws):

          THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
          INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933.  THESE SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF
          SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT.  COPIES OF
          THE AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING
          THEIR TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY
          THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE
          CORPORATION AT THE PRINCIPAL EXECUTIVE OFFICES OF THE CORPORATION.

          THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
          RESTRICTIONS UPON TRANSFER, AS SET FORTH IN AN AGREEMENT BETWEEN THE
          CORPORATION AND THE REGISTERED HOLDER, A COPY OF WHICH IS ON FILE AT
          THE PRINCIPAL OFFICE OF THE CORPORATION.  SUCH TRANSFER RESTRICTIONS
          ARE BINDING ON TRANSFEREES OF THESE SHARES.

          4.   The certificates evidencing the Parent Common Stock shall also
bear any legend required pursuant to any state, local or foreign law governing
such securities or the Reorganization Agreement.

          5.   The undersigned understands and acknowledges that the Parent
Common Stock has not been registered under the 1933 Act and Parent Common Stock
must be held indefinitely unless subsequently registered under the 1933 Act or
an exemption from such registration is available and that the Parent is
obligated to register the Parent Common Stock only in accordance with the terms
of the Registration Rights Agreement.

          6.   The undersigned acknowledges that the Parent Common stock shall
not be transferable except upon the conditions specified in this Agreement and
the Reorganization Agreement.

          7.   Prior to any proposed transfer of any Parent Common Stock, unless
there is in effect a registration statement under the 1933 Act covering the
proposed transfer, the undersigned shall

                                      -2-
<PAGE>
 
give written notice to the Company of its intention to effect such transfer.
Each such notice shall describe the manner and circumstances of the proposed
transfer in sufficient detail, and shall, if the Parent so requests, be
accompanied by either (i) a written opinion of legal counsel who shall be
satisfactory to Parent, addressed to Parent and satisfactory in form and
substance to Parent's counsel, to the effect that the proposed transfer of
Parent Common Stock may be effected without registration under the 1933 Act, or
(ii) a "No Action" letter from the Securities and Exchange Commission (the
"Commission") to the effect that the transfer of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such Parent
Common Stock shall be entitled to transfer such shares of Parent Common Stock in
accordance with the terms of the notice delivered by the holder to Parent. Each
certificate evidencing the shares of Parent Common Stock transferred as above
provided shall bear the appropriate restrictive legend set forth in Section (c)
above, except that such certificate shall not bear such restrictive legend if in
the opinion of counsel for Parent such legend is not required in order to
establish compliance with any provisions of the 1933 Act.

          8.   The undersigned is familiar with the provisions of Rule 144,
promulgated under the 1933 Act, which in substance, permits limited public
resale of "restricted securities" acquired, directly or indirectly from the
issuer thereof (or from an affiliate of such issuer) in a non-public offering
subject to the satisfaction of certain conditions, including, among other
things: (i) a public trading market then exists for the Parent Common Stock;
(ii) the availability of certain public information about Parent; (iii) the
resale occurring not less than one (1) year after the party has purchased, and
made full payment for, within the meaning of Rule 144, the securities to be
sold; and (iv) the sale being made through a broker in an unsolicited "broker
transaction" or in transactions directly with a market maker (as said term is
defined under the Securities Exchange Act of 1934) and the amount of securities
being sold during any three (3) month period not exceeding the specified
limitations stated therein, if applicable.  The undersigned further understands
that at the time the undersigned wishes to sell the shares of Parent Common
Stock received from Parent there may be no public market upon which to make such
a sale, and that, even if such a public market then exists, Parent may not be
satisfying the current public information requirements of Rule 144, and that, in
such event, the undersigned would be precluded from selling the shares of Parent
Common Stock received from Parent under Rule 144 even if the one (1) year
minimum holding period had been satisfied.  The undersigned further understands
that in the event all of the applicable requirements of Rule 144 are not
satisfied, registration under the 1933 Act, compliance with Regulation A, or
some other registration exemption would be required to sell the shares of Parent
Common Stock received from Parent.

          9.   The undersigned is the sole record and beneficial owner of
capital stock of the Company in the amount set forth next to its name on the
signature page hereto.  Such capital stock is not subject to any claim, lien,
pledge, charge, security interest or other encumbrance or to any rights of first

                                FORM OF OPINION

     Reference is made to the Agreement and Plan of Reorganization, dated as of
January 8, 1999 the "Reorganization Agreement"), excluding all listed exhibits
thereto, by and among Ticketmaster Online - CitySearch, Inc., a Delaware
corporation ("Parent"), and CityAuction, Inc., a California corporation (the
"Company"), which provides for the merger (the "Merger") of a wholly-owned
subsidiary of Parent with and into the Company. Reference is also made to the
Registration Rights Agreement, the Employment Agreements, the Non-Competition
Agreements and the Voting Agreement, dated January ___, 1999 by and among Parent
and certain shareholders of the Company (such agreements, including the
Reorganization Agreement, are referred to collectively hereinafter as the
"Agreements"). This opinion is rendered to you pursuant to Section 6.2(b) of the
Agreement, and all terms used herein have the meanings defined for them in the
Agreement unless otherwise defined herein.

     Based upon and subject to the foregoing, and except as set forth in the
Company Schedules, we are of the opinion that:

     1.  The Company is a corporation duly organized, validly existing and in
good standing under the laws of its state of incorporation and is duly qualified
as a foreign corporation and in good standing in each other jurisdiction in
which the failure to so qualify would have a material adverse effect on such
Company's business condition. The Company has no subsidiaries. The Company has
all requisite power and authority to own, operate and lease its properties and
to carry on its business as now being conducted.

     2.  (a)  The authorized capital stock of the Company consists (i) of
10,000,000 shares of Common Stock, of which 2,400,000 shares are issued and
outstanding and (ii) 1,015,000 shares of Preferred Stock, of which 415,000
shares, designated Series A Preferred Stock, are outstanding. All of such
outstanding shares have been duly authorized, validly issued, fully paid and 
non-assessable and have been issued in compliance with all applicable federal
and state securities laws. The outstanding shares of Company Capital Stock are
not subject to preemptive rights created by statute, the Articles of
Incorporation or Bylaws of the Company, or any agreement to which the Company is
a party or by which it may be bound. There are no voting agreements or voting
trusts with respect to any of the outstanding shares of capital stock of the
Company. The outstanding shares of capital stock of the Company are held by the
persons and in the amounts set forth in Section 3.2 of the Company Schedules.

         (b) The Company has reserved 300,000 shares of Company Common Stock for
issuance to employees and consultants pursuant to outstanding options (the
"Company Stock Options"), of which 15,019 were issued pursuant to the Company's
1998 Stock Option Plan (the "Company's Stock Option Plan") and 284,981 shares
remain available for future grant under the

                                      -1-
<PAGE>
 
plan. Section 3.2(b) of the Company Schedules sets forth for each outstanding
Company Stock Options the name of the holder of such option, the number of
shares of Company Common Stock subject to such option, the exercise price of
such option and the vesting schedule for such option, including the extent
vested to date. The Company has reserved 600,000 shares of Series A Preferred
Stock issuable upon exercise of a warrant issued to Snap! LLC (the "Warrant").
Except for the Company Stock Options described in Section 3.2(b) of the Company
Schedules and the Warrant, there are no options, warrants, calls, rights,
commitments or agreements of any character, written or oral, to which the
Company is a party or by which it is bound obligating the Company to issue,
deliver, sell, repurchase or redeem, or cause to be issued, delivered, sold,
repurchased or redeemed, any shares of the capital stock of the Company or
obligating the Company to grant, extend, accelerate the vesting of, change the
price of, otherwise amend or enter into any such option, warrant, call, right,
commitment or agreement. The Company's Stock Options and the Warrant have been
issued in compliance with all applicable federal and state securities laws. The
holders of Company Stock Options and the Warrant have given, or have properly
waived, any required notice prior to the Merger. As a result of the Merger,
Parent will be the record and beneficial owner of all outstanding capital stock
of the Company and, except for stock options granted pursuant to the Company's
Stock Option Plan [and the Warrant], rights to acquire capital stock of the
Company.

     3. The execution and delivery of the Reorganization Agreement, the
Agreement of Merger, the Non-Competition Agreement, the Employment Agreement(s)
and the Registration Rights Agreement (the "Agreements") do not, and the
consummation of the transactions contemplated by the Agreements will not,
conflict with or result in any violation of any statute, law, rule, regulation,
judgment, or, to our knowledge, any order, decree or ordinance applicable to the
Company or its properties or assets, or, conflict with or result in any material
breach or default (with or without notice or lapse of time, or both) under, or
give rise to a right of termination, cancellation, or acceleration of any
obligation or to loss of a material benefit under, or result in the creation of
a material lien or encumbrance on any of the properties or assets of the Company
pursuant to (i) any provision of the Articles of Incorporation or Bylaws of the
Company currently in effect or (ii) to the best of our knowledge, except as
disclosed in the Reorganization Agreement and the Company Schedules, any
agreement, contract, note, mortgage, indenture, lease, instrument, permit,
concession, franchise or license to which the Company is a party or by which the
Company or any of its properties or assets may be bound or affected.

     4. The Company has all requisite corporate power and authority to enter
into the Agreements, to perform its obligations thereunder and to consummate the
transactions contemplated thereby. The execution and delivery of the Agreements,
the performance by the Company of its obligations thereunder and the
consummation of the transactions contemplated thereby have been duly and validly
authorized by all necessary corporate action on the part of the Company, and
have been approved by the Board of Directors and shareholders of the Company. No
other corporate proceeding on the part of the Company is necessary to authorize
the Agreements by the Company or the performance of the Company's obligations
thereunder or the consummation of the transactions contemplated thereby. The
Agreements to which the Company is a party have been duly executed

                                      -2-
<PAGE>
 
and delivered by the Company and constitute legal, valid and binding obligations
of the Company, enforceable against the Company in accordance with their
respective terms.

     5.  No consent, approval, authorization or order of, or registration,
declaration or filing with, any Governmental Entity is required by or with
respect to the Company or in connection with the execution and delivery by the
Company of the Agreements to which it is a party, or the consummation by the
Company of the transactions contemplated thereby, except for (i) the filing of
the Merger Agreement by the California Secretary of State, (ii) such as have
been obtained or accomplished, and (iii) such consents, approvals, orders
authorizations, registrations, declarations and filings as may be required under
the laws of California, which if not obtained or made would not have a material
adverse effect on the business condition of the Company.

     6.  The Agreements have been duly approved and adopted by the affirmative
vote of a number of outstanding shares of the Company's capital stock that
equals or exceeds the number of such shares required to approve the Agreements,
under the California Corporations Code and the Company's Articles of
Incorporation.

     7.  There is no action, suit, proceeding, claim or investigation pending
or, to the best of our knowledge, threatened against the Company which could,
individually or in the aggregate, have a material adverse effect on the business
condition of the Company or which in any manner challenges or seeks to prevent,
enjoin, alter or materially delay any of the transactions contemplated by the
Agreements.

     8.  To the best of our knowledge, the Company has not received notice that
it would be, with the passage of time, in default or violation of any material
term, condition or provision of any material judgment, order, injunction or
stipulation applicable to the Company.

     THIS REGISTRATION RIGHTS AGREEMENT (the "Agreement"), is made as of March

     C.  The Reorganization Agreement provides for the execution and delivery of

        -------------------------

    In connection with the registration of the Registrable Securities, Parent
shall have the following obligations:

        a. Parent shall prepare promptly and file with the SEC a Registration
Statement with respect to the Registrable Securities as provided in Section
2(a), and thereafter use its reasonable commercial efforts to cause such
Registration Statement relating to Registrable Securities to become effective,
and keep the Registration Statement effective pursuant to Rule 415 at all times
until such date as is the earlier of (i) the date on which all of the
Registrable Securities have been sold and (ii) the date on which the Registrable
Securities (in the opinion of counsel to the Shareholders) may be immediately
sold without restriction (including without limitation as to volume by each
holder thereof) without registration under the 1933 Act (the "Registration
Period").

        b. Parent shall prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus used in connection with the Registration Statement as may be
necessary to keep the Registration Statement effective at all times during the
Registration Period, and, during such period, comply with the provisions of the
1933 Act with respect to the disposition of all Registrable Securities of the
Company covered by the Registration Statement until such time as all of such
Registrable Securities

                                      -2-
<PAGE>
 
have been disposed of in accordance with the intended methods of disposition by
the seller or sellers thereof as set forth in the Registration Statement.

        c. Parent shall furnish to the Shareholders (i) promptly after the
Registration Statement is prepared and publicly distributed, filed with the SEC,
or received by Parent, one copy of the Registration Statement and any amendment
thereto, each preliminary prospectus and prospectus and each amendment or
supplement thereto and (ii) such number of copies of a prospectus, including a
preliminary prospectus, and all amendments and supplements thereto and such
other documents as the Shareholders may reasonably request in order to
facilitate the disposition of the Registrable Securities owned by such
Shareholders. Parent will immediately notify the Shareholders by facsimile of
the effectiveness of the Registration Statement or any post-effective amendment.
Parent will promptly file an acceleration request as soon as practicable
following the resolution or clearance of all SEC comments or, if applicable,
following notification by the SEC that the Registration Statement or any
amendment thereto will not be subject to review.

        d. Parent shall use reasonable efforts to (i) register and qualify the
Registrable Securities covered by the Registration Statement under such other
securities or "blue sky" laws of such jurisdictions in the United States as the
Shareholders reasonably request, (ii) prepare and file in those jurisdictions
such amendments (including post-effective amendments) and supplements to such
registrations and qualifications as may be necessary to maintain the
effectiveness thereof during the Registration Period, (iii) take such other
actions as may be necessary to maintain such registrations and qualifications in
effect at all times during the Registration Period, and (iv) take all other
actions reasonably necessary or advisable to qualify the Registrable Securities
for sale in such jurisdictions; provided, however, that Parent shall not be
                                --------  -------
required in connection therewith or as a condition thereto to (a) qualify to do
business in any jurisdiction where it would not otherwise be required to qualify
but for this Section 3(d), (b) subject itself to general taxation in any such
jurisdiction, (c) file a general consent to service of process in any such
jurisdiction, (d) provide any undertakings that cause the Company undue expense
or burden, or (e) make any change in its charter or bylaws.

        e. In the event the Shareholders select underwriters for the offering,
Parent shall enter into and perform its obligations under an underwriting
agreement, in usual and customary form, including, without limitation, customary
indemnification and contribution obligations, with the underwriters of such
offering.

        f. As promptly as practicable after becoming aware of such event, Parent
shall notify the Shareholders of (x) the issuance by the SEC of a stop order
suspending the effectiveness of the Registration Statement, (y) the happening of
any event, of which Parent has knowledge, as a result of which the prospectus
included in the Registration Statement, as then in effect, includes an untrue
statement of a material fact or omission to state a material fact required to be
stated therein or necessary to make the statements therein not misleading, (z)
the occurrence or existence of any pending corporate development that, in the
reasonable discretion of Parent, makes it appropriate to suspend the
availability of the Registration Statement and use its best efforts promptly to
prepare a supplement or amendment to the Registration Statement to correct such
untrue statement or omission, and deliver such number of copies of such
supplement or amendment to the Shareholders, 

                                      -3-
<PAGE>
 
as the Shareholders may reasonably request; provided that, for not more than
twenty (20) consecutive trading days (or a total of not more than thirty (30)
trading days in any twelve (12) month period) (or 60 trading days in any 12
month period, in the case of an event described in clause (z) above that arises
from an acquisition or a probable acquisition or financing, recapitalization,
business combination or other similar transaction), Parent may delay the
disclosure of material non-public information concerning Parent (as well as
prospectus or Registration Statement updating) the disclosure of which at the
time is not, in the good faith opinion of Parent, the best interests of Parent
(an "Allowed Delay"); provided, further, that Parent shall promptly (i) notify
the Shareholders in writing of the existence of (but in no event, without the
prior written consent of the Shareholders, shall Parent disclose to such
Shareholder any of the facts or circumstances regarding) material non-public
information giving rise to an Allowed Delay and (ii) advise the Shareholders in
writing to cease all sales under the Registration Statement until the end of the
Allowed Delay. Upon expiration of the Allowed Delay, Parent shall again be bound
by the first sentence of this Section 3(f) with respect to the information
giving rise thereto.

        g. Parent shall use its best efforts to prevent the issuance of any stop
order or other suspension of effectiveness of a Registration Statement, and, if
such an order is issued, to obtain the withdrawal of such order at the earliest
possible moment and to notify each Shareholder who holds Registrable Securities
being sold (or, in the event of an underwritten offering, the managing
underwriters) of the issuance of such order and the resolution thereof.

        h. Parent shall permit a single firm of counsel designated by the
Shareholders to review the Registration Statement and all amendments and
supplements thereto (as well as all requests for acceleration or effectiveness
thereof) a reasonable period of time prior to their filing with the SEC, and not
file any document in a form to which such counsel reasonably objects and will
not request acceleration of the Registration Statement without prior notice to
such counsel. The sections of the Registration Statement covering information
with respect to the Shareholders, the Shareholders' beneficial ownership of
securities of Parent or the Shareholders' intended method of disposition of
Registrable Securities shall conform to the information provided to Parent by
each of the Shareholders.

        i. Parent shall (i) cause all the Registrable Securities covered by the
Registration Statement to be listed on each national securities exchange on
which securities of the same class or series issued by Parent are then listed,
if any, if the listing of such Registrable Securities is then permitted under
the rules of such exchange, or (ii) secure the designation and quotation, of all
the Registrable Securities covered by the Registration Statement on the Nasdaq
or, if not eligible for the Nasdaq on the Nasdaq SmallCap.

    4.  OBLIGATIONS OF THE SHAREHOLDERS.
        -------------------------------

    In connection with the registration of the Registrable Securities, the
Shareholders shall have the following obligations:

                                      -4-
<PAGE>
 
        a. It shall be a condition precedent to the obligations of Parent to
complete the registration pursuant to this Agreement with respect to the
Registrable Securities that the Shareholders shall furnish to Parent such
information regarding themselves, the Registrable Securities held by them and
the intended method of disposition of the Registrable Securities held by them as
shall be reasonably required to effect the registration of such Registrable
Securities and shall execute such documents in connection with such registration
as Parent may reasonably request. At least three (3) business days prior to the
first anticipated filing date of the Registration Statement, Parent shall notify
the Shareholders of the information Parent requires from the Shareholders.

        b. The Shareholders, by their acceptance of the Registrable Securities,
agree to cooperate with Parent as reasonably requested by Parent in connection
with the preparation and filing of the Registration Statement hereunder, unless
the Shareholders have notified Parent in writing of the Shareholders' election
to exclude all of their Registrable Securities from the Registration Statement.

        c. In the event the Shareholders determine to engage the services of an
underwriter, the Shareholders agree to enter into and perform the Shareholders'
obligations under an underwriting agreement, in usual and customary form,
including, without limitation, customary indemnification and contribution
obligations, with the managing underwriter of such offering and take such other
actions as are reasonably required in order to expedite or facilitate the
disposition of the Registrable Securities.

        d. The Shareholders agree that, upon receipt of any notice from Parent
of the happening of any event of the kind described in Section 3(f) or 3(g), the
Shareholders will immediately discontinue disposition of Registrable Securities
pursuant to the Registration Statement covering such Registrable Securities
until the Shareholders' receipt of the copies of the supplemented or amended
prospectus contemplated by Section 3(f) or 3(g) and, if so directed by Parent,
the Shareholders shall deliver to Parent (at the expense of Parent) or destroy
(and deliver to Parent a certificate of destruction) all copies in the
Shareholders' possession, of the prospectus covering such Registrable Securities
current at the time of receipt of such notice.

        e. The Shareholders may not participate in any underwritten registration
hereunder unless they (i) agree to sell their Registrable Securities on the
basis provided in any underwriting arrangements in usual and customary form
entered into by Parent, (ii) complete and execute all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements, and (iii) agree to
pay all underwriting discounts and commissions and any expenses in excess of
those payable by Parent pursuant to Section 5 below.

    5.  EXPENSES OF REGISTRATION.
        ------------------------

    All reasonable expenses, other than underwriting discounts and commissions,
incurred in connection with registrations, filings or qualifications pursuant to
Sections 2 and 3, including, without limitation, all registration, listing and

3(h) hereof, up to a maximum of [$20,000], shall be borne by Parent.

    6.  INDEMNIFICATION.
        ---------------

    In the event any Registrable Securities are included in a Registration

Act of 1934, as amended (the "1934 Act"), if any, (iii) any underwriter (as
defined in the 1933 Act) for the Shareholders, and (iv) the directors, officers,
partners, employees and each person who controls any such underwriter within the
meaning of the 1933 Act or the 1934 Act, if any (each, an "Indemnified Person"),
against any joint or several losses, claims, damages, liabilities or expenses
(collectively, together with actions, proceedings or inquiries by any regulatory
or self-regulatory organization, whether commenced or threatened, in respect
thereof, "Claims") to which any of them may become subject insofar as such
Claims arise out of or are based upon: (i) any untrue statement or alleged
untrue statement of a material fact in a Registration Statement or the omission
or alleged omission to state therein a material fact required to be stated or
necessary to make the statements therein not misleading; (ii) any untrue
statement or alleged untrue statement of a material fact contained in any
preliminary prospectus if used prior to the effective date of such Registration
Statement, or contained in the final prospectus (as amended or supplemented, if

omission or alleged omission to state therein any material fact necessary to
make the statements made therein, in light of the circumstances under which the
statements therein were made, not misleading; or (iii) any violation or alleged

without limitation, any state securities law, or any rule or regulation
thereunder relating to the offer or sale of the Registrable Securities (the
matters in the foregoing clauses (i) through (iii) being, collectively,

respect to the number of legal counsel, Parent shall reimburse the Indemnified
Person, promptly as such expenses are incurred and are due and payable, for any
reasonable legal fees or other reasonable expenses incurred by them in
connection with investigating or defending any such Claim. Notwithstanding
anything to the contrary contained herein, the indemnification agreement
contained in this Section 6(a): (i) shall not apply to a Claim arising out of or
based upon a Violation which occurs in reliance upon and in conformity with
information furnished in writing to Parent by any Indemnified Person or
underwriter for such Indemnified Person expressly for use in connection with the
preparation of the Registration Statement or any such amendment thereof or
supplement thereto, if such prospectus was timely made available by Parent
pursuant to Section 3(c) hereof; (ii) shall not apply to amounts paid in
settlement of any Claim if such settlement is effected without the prior written
consent of Parent, which consent shall not be unreasonably withheld; and (iii)
with respect to any preliminary prospectus, shall not inure to the benefit of
any Indemnified Person if the untrue statement or omission of material fact
contained in the preliminary prospectus was corrected on a

                                      -6-
<PAGE>
 
timely basis in the prospectus, as then amended or supplemented, such corrected
prospectus was timely made available by Parent pursuant to Section 3(c) hereof,
and the Indemnified Person was promptly advised in writing not to use the
incorrect prospectus prior to the use giving rise to a Violation and such
Indemnified Person, notwithstanding such advice, used it. Such indemnity shall
remain in full force and effect regardless of any investigation made by or on
behalf of the Indemnified Person.

        b. In connection with any Registration Statement in which the
Shareholders are participating, the Shareholders agree to indemnify, hold
harmless and defend, to the same extent and in the same manner set forth in
Section 6(a), Parent, each of its directors, each of its officers who signs the
Registration Statement, each person, if any, who controls Parent within the
meaning of the 1933 Act or the 1934 Act, any underwriter and any other
stockholder selling securities pursuant to the Registration Statement or any of
its directors or officers or any person who controls such stockholder or
underwriter within the meaning of the 1933 Act or the 1934 Act (collectively and
together with an Indemnified Person, an "Indemnified Party"), against any Claim
to which any of them may become subject, under the 1933 Act, the 1934 Act or
otherwise, insofar as such Claim arises out of or is based upon any Violation by
such Shareholder, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished to Parent by such Shareholder expressly for use in connection with
such Registration Statement; and subject to Section 6(c) such Shareholder will
reimburse any legal or other expenses (promptly as such expenses are incurred
and are due and payable) reasonably incurred by them in connection with
investigating or defending any Claim; provided, however, that the indemnity
                                      --------  -------
agreement contained in this Section 6(b) shall not apply to amounts paid in
settlement of any Claim if such settlement is effected without the prior written
consent of such Shareholder, which consent shall not be unreasonably withheld;
provided, further, however, that the Shareholder shall be liable under this
--------  -------  -------
Agreement (including this Section 6(b)) for only that amount as does not exceed
the net proceeds to such Shareholder as a result of the sale of Registrable
Securities pursuant to such Registration Statement. Such indemnity shall remain
in full force and effect regardless of any investigation made by or on behalf of
such Indemnified Party. Notwithstanding anything to the contrary contained
herein, the indemnification agreement contained in this Section 6(b) with
respect to any preliminary prospectus shall not inure to the benefit of any
Indemnified Party if the untrue statement or omission of material fact contained
in the preliminary prospectus was corrected on a timely basis in the prospectus,
as then amended or supplemented.

        c. Promptly after receipt by an Indemnified Person or Indemnified Party
under this Section 6 of notice of the commencement of any action (including any
governmental action), such Indemnified Person or Indemnified Party shall, if a
Claim in respect thereof is to be made against any indemnifying party under this
Section 6, deliver to the indemnifying party a written notice of the
commencement thereof, and the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume control of the
defense thereof with counsel mutually satisfactory to the indemnifying party and
the Indemnified Person or the Indemnified Party, as the case may be; provided,
                                                                     --------
however, that an Indemnified Person or Indemnified Party shall have the right to
-------
retain its own counsel with the fees and expenses to be paid by the indemnifying
party, if, in the reasonable

                                      -7-
<PAGE>
 
opinion of counsel retained by the indemnifying party, the representation by
such counsel of the Indemnified Person or Indemnified Party and the indemnifying
party would be inappropriate due to actual or potential differing interests
between such Indemnified Person or Indemnified Party and any other party
represented by such counsel in such proceeding. The indemnifying party shall pay
for only one separate legal counsel for the Indemnified Persons or the
Indemnified Parties, as applicable, and such legal counsel shall be selected by
the Shareholders, if the Shareholders are entitled to indemnification hereunder,
or Parent, if Parent is entitled to indemnification hereunder, as applicable.
The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall not relieve such
indemnifying party of any liability to the Indemnified Person or Indemnified
Party under this Section 6, except to the extent that the indemnifying party is
actually prejudiced in its ability to defend such action. The indemnification
required by this Section 6 shall be made by periodic payments of the amount
thereof during the course of the investigation or defense, as such expense,
loss, damage or liability is incurred and is due and payable.

                                AMENDMENT NO. 1

                                      TO

                     AGREEMENT AND PLAN OF REORGANIZATION

     THIS AMENDMENT NO. 1 TO AGREEMENT AND PLAN OF REORGANIZATION (this
"Amendment") is entered into as of March 19, 1999, by and between Ticketmaster
Online -CitySearch, Inc., a Delaware corporation ("Parent"), Nero Acquisition
Corporation, a California corporation and wholly-owned subsidiary of Parent
("Sub"), CityAuction, Inc., a California corporation (the "Company"), Andrew
Rebele and Monica Lee (collectively, the "Shareholders").

                                   RECITALS

     A.   Parent and the Company are parties to that certain Agreement and Plan
of Reorganization, dated as of January 8, 1999 (the "Reorganization Agreement"),
subject to the terms and conditions of which Sub will merge with and into the
Company (the "Merger"). Capitalized terms not otherwise defined herein shall
have the meanings ascribed to them in the Reorganization Agreement.

     B.   On February __, 1999, the Company restated its Articles of
Incorporation, changing the liquidation preference of the holders of the Series
A Preferred Stock to an amount equal to $0.50 per share.

     C.   Parent and the Company wish to amend the Reorganization Agreement upon
the terms set forth in this Amendment. 

     NOW, THEREFORE, the parties hereby agree as follows:

     1.   Amended Provisions. Sections 2.1(c), (d) and (e) of the Reorganization
Agreement shall be amended and restated in their entirety as follows:

     "(c)  Conversion of Capital Stock of the Company.  Subject to Sections 
           ------------------------------------------                       
2.1(d), (e), (f), (g) and (h) below, each issued and outstanding share of
preferred stock of the Company, $0.01 par value ("COMPANY PREFERRED STOCK")
(other than shares canceled pursuant to Section 2.1(b)), and each issued and
outstanding share of common stock of the Company, $0.01 par value, ("COMPANY
COMMON STOCK") (other than shares cancelled pursuant to Section 2.1(b)), that is
issued and outstanding immediately prior to the Effective Time shall
automatically be canceled and extinguished and converted, without any action on
the part of the holder thereof into the right to receive the number of shares of
Parent Common Stock calculated as set forth below.

     For purposes of this Section 2.1(c), the following terms shall have the
meanings set forth below:
<PAGE>
 
          "Average Trading Price" shall mean average of the closing prices of
           ---------------------                                             
the securities on the NASDAQ National Market System over the 30-day period
ending three (3) days prior to the Closing.

          "Liquidation Preference Amount" shall mean $207,500.
           -----------------------------                      

          "Preference Shares" shall mean the number of shares of Parent Common
           -----------------                                                  
Stock equal to the Liquidation Preference divided by the Average Trading Price.

          "Primary Exchange Ratio" shall equal the Preference Shares divided by
           ----------------------                                              
415,000 (the number of outstanding shares of Company Preferred Stock).

          "Remainder Shares" shall equal the number of shares of Parent Common
           ----------------                                                   
Stock equal to 800,000 shares minus the Preference Shares.

          "Secondary Exchange Ratio" shall equal the Remainder Shares divided by
           ------------------------                                             
2,837,394 (the number of outstanding shares of Parent capital Stock plus
outstanding stock options).

     The Primary Exchange Ratio and the Secondary Ratio shall be subject to
recalculation in the manner set forth in the definitions above in the event the
number of outstanding shares of Company Preferred Stock of Common Stock or
outstanding Company Stock options is changed prior to the Effective Time.

     Each holder of Company Preferred Stock shall be entitled to receive the
number of shares of Parent Common Stock at the Effective Time equal to the
following:

          [Number of shares of Company Preferred Stock held multiplied by the
Primary Exchange Ratio] plus [Number of shares of Preferred Stock held
multiplied by the Secondary Exchange Ratio]

     Each holder of Company Common Stock shall be entitled to receive the number
of shares of Parent Common Stock at the Effective Time equal to the following:

          [Number of shares of Company Common Stock held multiplied by the
Secondary Exchange Ratio]

     FOR EXAMPLE, if the Average Trading Price equaled $45, the Primary Exchange
Ratio would equal 0.01111111 and the Secondary Exchange Ratio would equal
0.280323737.  In such event, a holder of 400,000 shares of Company Preferred
Stock would receive 116,574 shares of Parent Common Stock at the Effective Time,
and a holder of 400,000 shares of Company Common Stock would receive 112,129
shares of Parent Common Stock at the Effective Time.

          (d)  Adjustment of Exchange Ratios.  If, between the date of this
               -----------------------------                               
Agreement and the Effective Time, the outstanding shares of Parent Common Stock
(or, subject to Section 5.1 below, Company Preferred Stock or Common Stock)
shall have been changed into a different 

                                      -2-
<PAGE>
 
number of shares or a different class by reason of any reclassification, split-
up, stock dividend, stock combination, then the Primary and Secondary Exchange
Ratios shall be correspondingly adjusted.

          (e)  Dissenters' Rights.  Any shares of Company Preferred Stock or
               ------------------                                           
Common Stock held by a holder who has properly exercised dissenters' rights for
such shares in accordance with the California Code and who, as of the Effective
Time, has not effectively withdrawn or lost such dissenters' rights ("DISSENTING
SHARES") shall not be converted into Parent Common Stock but shall be converted
into the right to receive such consideration as may be determined to be due with
respect to such Dissenting Shares pursuant to the California Code.  The Company
shall give Parent prompt notice of any demand received by the Company to require
the Company to purchase shares of Company Preferred Stock or Common Stock, and
Parent shall have the right to participate in all negotiations and proceedings
with respect to such demand.  The Company agrees that, except with the prior
written consent of Parent, or as required under the California Code, it will not
voluntarily make any payment with respect to, or settle or offer to settle, any
such purchase demand.  Each holder of Dissenting Shares (a "DISSENTING
SHAREHOLDER") who, pursuant to the provisions of the California Code, becomes
entitled to payment of the value of shares of Company Common Stock shall receive
payment therefor (but only after the value therefor shall have been agreed upon
or finally determined pursuant to such provisions).  In the event of legal
obligation, after the Effective Time, to deliver shares of Parent Common Stock
to any holder of shares of Company Preferred Stock or Common Stock who shall
have failed to make an effective purchase demand or shall have lost its status
as a Dissenting Shareholder, Parent shall issue and deliver, upon surrender by
such Dissenting Shareholder of such holder's certificate or certificates
representing shares of capital stock of the Company, the shares of Parent Common
Stock to which such Dissenting Shareholder is then entitled under this Section
2.1 and the Merger Agreement."

          The second sentence of Section 2.1(i)(ii) is amended and restated to
read as follows: "The exercise price for such option shall be equal to the
closing price of the Parent Common Stock on the NASDAQ National Market System on
the date of the Closing."

          The first sentence of Section 2.1(f) is amended and restated to read
as follows: "No fractional shares of Parent Common Stock shall be issued, but in
lieu thereof each holder of shares of Company Preferred Stock or Common Stock
who would otherwise be entitled to receive a fraction of a share of Parent
Common Stock shall receive from Parent an amount of cash equal to the per share
market value of Parent Common Stock (based on the last sales price of Parent
Common Stock as reported on the Nasdaq National Market on the Effective Date)
multiplied by the fraction of a share of Parent Common Stock to which such
holder would otherwise be entitled."

           The first sentence of Section 2.2(g) shall be amended and restated to
read as follows:

               The maximum consideration to be paid by Parent (including Parent
Common Stock to be reserved for issuance upon exercise of the Company's options
assumed by Parent  

                                      -3-
<PAGE>
 
pursuant to Section 5.16) pursuant to the Merger shall be equal to (i) 800,000
shares of Parent Common Stock (plus any additional shares of Parent Common Stock
exchanged in the Merger at the Secondary Exchange Ratio for shares of capital
stock of the Company issued upon exercise of the Warrant (as defined in Section
3.2)) plus (ii) an additional 200,000 shares of Parent Common Stock to be
reserved for issuance upon exercise of options to purchase Parent Common Stock
to be granted to the employees of CityAuction as set forth in Section 2.1(i)(b)
below.

          The second paragraph of Section 2.1(h)(i)(B) is amended and restated
to read as follows:  "The Pledged Shares shall be withheld from the shareholders
in relation to the prorated percentage of shares of Parent Common Stock issuable
to such shareholders in the Merger as set forth in Section 2.1(c)."

     Sections 2.2 (c), (d), (e) and (f) shall be amended and restated in their
entirety as follows:

          "(c) Exchange Procedures.  As soon as practicable after the Effective
               -------------------                                             
Time, the Surviving Corporation shall cause to be mailed to each holder of
record of a certificate or certificates which immediately prior to the Effective
Time represented outstanding shares of Company Preferred Stock or Common Stock
(the "Certificates") whose shares are being converted into Parent Common Stock
pursuant to Section 2.1 and the Merger Agreement, (i) a letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon delivery of the Certificates to the
Exchange Agent and shall be in such form and have such other provisions as
Parent may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for Parent Common Stock.  Upon
surrender of a Certificate for cancellation to the Exchange Agent or to such
other agent or agents as may be appointed by Parent, together with such letter
of transmittal, duly executed, the holder of such Certificate shall be entitled
to receive in exchange therefor the number of shares of Parent Common Stock to
which the holder of Company Preferred Stock or Common Stock is entitled pursuant
to Section 2.1.  The Certificate so surrendered shall forthwith be canceled.  In
the event of a transfer of ownership of Company Preferred Stock or Common Stock
which is not registered on the transfer records of the Company, the appropriate
number of shares of Parent Common Stock may be delivered to a transferee if the
Certificate representing such capital stock of the Company is presented to the
Exchange Agent and accompanied by all documents required to evidence and effect
such transfer and to evidence that any applicable stock transfer taxes have been
paid.  Until surrendered as contemplated by this Section 2.2, each Certificate
shall be deemed at any time after the Effective Time to represent the right to
receive upon such surrender the number of shares of Parent Common Stock as
provided by this Section 2 and the provisions of the California Code.

          (d)  No Further Ownership Rights in Capital Stock of the Company.  All
               -----------------------------------------------------------      
Parent Common Stock delivered upon the surrender for exchange of shares of
Company Preferred Stock or Common Stock in accordance with the terms hereof
shall be deemed to have been delivered in full satisfaction of all rights
pertaining to such shares of Company Preferred Stock or Common Stock, and
following the Effective Time, the Certificates shall have no further rights to,
or 

                                      -4-
<PAGE>
 
ownership in, shares of capital stock of the Company. There shall be no further
registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of Company Preferred Stock or Common Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Section 2.

          (e)  Lost, Stolen or Destroyed Certificates.  In the event any
               --------------------------------------                   
certificates evidencing shares of Company Preferred Stock or Common Stock shall
have been lost, stolen or destroyed, the Exchange Agent shall make payment in
exchange for such lost, stolen or destroyed certificates, upon the making of an
affidavit of that fact by the holder thereof, such shares of Parent Common Stock
and cash for fractional shares, if any, as may be required pursuant to Section
2.1(f); provided, however, that Parent may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed certificates to deliver a bond in such sum as it may reasonably direct
as indemnity against any claim that may be made against Parent or the Exchange
Agent with respect to the certificates alleged to have been lost, stolen or
destroyed.

          (f)  No Liability.  Notwithstanding anything to the contrary in this
               ------------                                                   
Section 2.2, none of the Exchange Agent, the Surviving Corporation or any party
hereto shall be liable to a holder of shares of Company Preferred or Common
Stock for any amount paid to a public official pursuant to any applicable
abandoned property, escheat or similar law."

     2.   Agreement of Merger. The parties agree that the Agreement of Merger
shall be revised to reflect the amendments, described above.

     3.   Authority.  The Company represents and warrants that the execution and
delivery of this Amendment by the Company has been duly authorized by all
necessary corporate action on the part of the Company, that this Amendment has
been duly executed and delivered by the Company and that this Amendment is the
valid and binding obligation of the Company, enforceable in accordance with its
terms, except that such enforceability may be subject to (i) bankruptcy,
insolvency, reorganization or other similar laws affecting or relating to
enforcement of creditors' rights generally and (ii) general equitable
principles.  Parent represents and warrants that the execution and delivery of
this Amendment by Parent has been duly authorized by all necessary corporate
action on the part of Parent, that this Amendment has been duly executed and
delivered by Parent and that this Amendment is the valid and binding obligation
of Parent, enforceable in accordance with its terms, except that such
enforceability may be subject to (i) bankruptcy, insolvency, reorganization or
other similar laws affecting or relating to enforcement of creditors' rights
generally and (ii) general equitable principles.

     4.   Governing Law; Counterparts. The internal laws of the State of
California (irrespective of its choice of law principles) will govern the
validity of this Amendment, and this Amendment may be executed in counterparts
each of which shall be deemed an original and all of which shall constitute one
instrument.
