                                  -----------

WHEREAS, GI owns and markets its computerized reservations and ticketing and
other services ("Galileo Services"); and

WHEREAS, Vendor owns and operates a computer system ("Orbit System") and has
developed a computerized database ("TravelFile"); and

WHEREAS, GI has developed a Galileo Services communications capability (the
"Direct Link") which will enable Galileo Subscribers to query TravelFile and
possibly, the travel related products and services of third party vendors
(respectively "Third Party Products" and "Third Party Vendors"); and

WHEREAS, Vendor desires to participate in Galileo Services for purposes of
facilitating the display of TravelFile and Third Party Products, and, at GI's
sole option, provide booking capabilities for Third Party Products, through
Galileo Services via the Direct Link;

NOW, THEREFORE, in consideration of the premises and the mutual obligations
hereinafter set forth, GI and Vendor hereby agree as follows:

1.   DEFINITIONS
     -----------

     For the purpose of this Agreement and its attachment, the following words
     and terms shall have the following meanings:

     A.   "Ancillary Services" means limited access to Galileo Services by
          Vendor solely for the purpose of facilitating the display of
          TravelFile or Third Party Products.

     B.   "TravelFile" means Vendor's computerized database, which resides on
          the Orbit System, which contains listings and information about
          TravelFile Advertisers' (as defined in Section 1.I below) products and
          services.

     D.   "Direct Link" means a Galileo Services communications capability
          which, when a request for information or a transaction is being made
          for a TravelFile Advertisers' products or services through TravelFile,
          or for Third Party Products, by a GS through Galileo Services,
          simultaneously transmits the transaction data or request to the Orbit
          System.

     E.   "Galileo Services" or "Galileo" means GI's computerized reservations
          and ticketing service and other services. For purposes of this
          Agreement, Galileo Services may include services of Galileo(R),
          Appolo(R) and any other computerized reservation system or authorized
          agent thereof with whom GI has an agreement to distribute such
          services or similar service ("Related CRS"). Said parties shall not be
          considered third parties under this Agreement.

     F.   "Galileo Subscriber" or "GS" means any authorized user of Galileo
          Services or any portion thereof.

Galileo and Apollo are registered trademarks of Galileo International in the
United States and/or other countries.
<PAGE>

     G.   "Third Party Vendor" means a third party, other than a TravelFile
          Advertiser, who has been approved by GI and is included in Attachment
          A, who has contracted with Vendor to provide access to its travel-
          related products and services through the Direct Link to Galileo
          Subscribers.

     H.   "Third Party Products" means information and the travel related
          products and services of the Third Party Vendors as set forth in
          Attachment A hereto.

     I.   "TravelFile Advertiser" means a third party entity who has contracted
          with Vendor to list its travel related products or services through
          TravelFile, where such products or services directly benefit the
          consumer and are generally considered destination related. For the
          purposes of this Agreement, a vendor whose services are listed in
          TravelFile does not have to be under contract with the Vendor to be
          included in a TravelFile vendor listing.

2.   RESPONSIBILITIES OF VENDOR
     --------------------------

     A.   Vendor, at its own cost, shall coordinate TravelFile Services with
          Galileo Services to provide as advantageous and uniform reservations
          services to all GSs as it provides through other computerized
          reservations systems.

     B.   Vendor shall be responsible for ensuring that the contents of
          TravelFile Services provided by it under this Agreement are current
          and accurate.

     C.   Vendor is responsible for continually maintaining TravelFile,
          including, but not limited to, the appropriate maintenance of rates,
          charges, procedures, availability, and marketing information, pursuant
          to the following guidelines:

          (i)   All data is to be logically indexed by Vendor;
          (ii)  All data is to be stored by Vendor in a "user friendly" format
                requiring a minimum of input by GS to retrieve;
          (iii) All data must be displayed in a literate, easily discernible
                manner; and
          (iv)  Data must be maintained by Vendor in a timely manner and all
                obsolete data must be deleted.

     D.   Vendor's use of the Direct Link shall be limited to the provision of
          TravelFile to GSs through Galileo Services, or the provision of Third
          Party Products approved by GI and included in Attachment A to this
          Agreement. This does not include the acceptance of bookings, unless
          terms related to the acceptance of bookings are specifically outlined
          in Attachment A hereto. The data provided by Vendor through TravelFile
          shall be of a quality and content at least equal to that provided by
          Vendor through other computerized reservations systems.

     E.   Vendor shall be responsible for all of its costs associated with the
          advertising, promotion and marketing of the availability of TravelFile
          to others, including GSs. Vendor may use the GI service marks
          "Galileo" and "Apollo" in promotional materials, provided that GI's
          written approval for each such use is first obtained and Vendor
          complies with any and all conditions GI may impose to protect the use
          of GI's service marks. Vendor must state in all such materials that
          "Galileo and Apollo are registered trademarks or service marks of
          Galileo International".

     F.   Vendor is solely responsible for processing and responding to
          questions and correspondence from GSs, consumers and others regarding
          TravelFile or Third Party Products provided pursuant to this
          Agreement.

     G.   Vendor shall make available to GI the same improvements, enhancements
          or additions to TravelFile offered by Vendor to other end users of
          other computerized reservations systems.

     H.   If Vendor participates in two or more computerized reservations
          systems by offering TravelFile, then Vendor agrees not to recommend to
          others any other systems over Galileo Services and it shall not
          disparage Galileo Services in any way.

                                      -2-
<PAGE>

     I.   Vendor shall pay one hundred percent (100%) of the costs associated
          with the provision of telecommunications circuit(s) for the Direct
          Link between Galileo and the Orbit System and Vendor shall pay GI for
          such charges within thirty (30) days after the date of each monthly
          invoice. In addition to monthly line charges, these communications
          costs include all charges for installation, deinstallation, circuit
          moves, circuit upgrades, and protocol changes. In the event Vendor
          requires GI hardware (terminals, printers, etc.), such hardware shall
          be contracted for under a separate Ancillary Services Agreement.

     J.   Upon execution of this Agreement, Vendor shall establish, and Vendor
          shall enforce consistently and non-discriminatorily during the term of
          this Agreement, objective and verifiable standards of quality and
          performance of all of Vendor's travel information suppliers whose
          products and services are reflected in TravelFile.

     K.   Vendor shall be responsible for all Third Party Product and TravelFile
          Advertiser data and shall be subject to the same responsibilities as
          defined in this Agreement as if the data were its own.

     L.   Following execution of this Agreement Vendor reserves the right to
          contract with additional third party vendors and, if approved by GI,
          the Agreement shall be amended to add such approved third party vendor
          to Attachment A. Vendor agrees to terminate the display of any
          transmission of Third Party Vendor data immediately unless such Third
          Party Vendor is indicated on the Attachment A to this Agreement, or an
          agreement has been reached between Vendor and GI to offer said service
          and this Agreement is amended to indicate same.

     M.   Vendor shall provide GI with thirty (30) days prior written notice in
          the event of termination of any Third Party Vendor listed on
          Attachment A.

3.   RESPONSIBILITIES OF GI
     ----------------------

     A.   During the term of and in accordance with this Agreement, GI shall
          provide GSs with access to TravelFile and Third Party Products through
          Galileo Services via the Direct Link.

     B.   GI shall communicate procedures to GSs which allow them to access
          TravelFile through Galileo Services.

     C.   GI shall inform GSs of TravelFile and Third Party Products, as made
          available under this Agreement; however, GI shall have no liability of
          any kind whatsoever to any party as a result of or in any way
          associated with the contents or accuracy of TravelFile or Third Party
          Products provided by Vendor through Galileo Services.

     D.   GI reserves the right to request that Vendor discontinue display of
          information in TravelFile or Third Party Products which, in GI's
          reasonable judgment, fail to conform to acceptable standards of
          practice and service or to the terms of this Agreement; provided,
          however, GI shall give Vendor thirty (30) days prior written notice in
          order that Vendor may remedy such defects in said standards.
          Notwithstanding the provisions of the previous sentence, GI reserves
          the right, upon notifying Vendor, to request Vendor to immediately
          delete any subject matter which it reasonably considers to be
          inappropriate, misleading or defamatory.

     E.   Except for those duties set forth herein, GI assumes no responsibility
          for any other duties in connection with Vendor's services or any
          TravelFile Advertiser or Third Party Products, including without
          limitation, providing written confirmations of reservations,
          confirmation number call-backs, answering complaints or any other form
          of customer follow-up or contact.

     F.   GI may advertise, promote and market the availability of TravelFile or
          Third Party Products provided to others pursuant to this Agreement,
          including GSs. GI may use Vendor's tradename "TravelFile" in such
          advertising, promotional and marketing efforts provided that Vendor's
          written approval for each such use is first obtained and GI complies
          with any and all conditions Vendor may impose to protect the use of
          Vendor's tradename. GI must state in all such materials that
          "TravelFile is a registered trademark of Orbit Network".

4.   FEES AND PAYMENTS
     -----------------

     A.   Vendor agrees to pay for services covered by this Agreement as set
          forth on Attachment A hereto.

     B.   Vendor shall reimburse GI for one hundred percent (100%) of the
          installation charges and recurring monthly cost of the
          telecommunications services referred to in Article 2.I and any fees
          associated with de-installation and circuit moves.

     C.   GI shall invoice Vendor for all fees and charges hereunder. The
          determination of Vendor's total invoiced fees and charges shall be
          based solely on Galileo's records. All payments required under this
          Agreement are due within thirty (30) days after receipt of invoice;
          failure to pay invoices in timely fashion shall subject Vendor to a
          late payment charge of one and one-half percent (1 1/2%) of the
          delinquent balance per month compounded or the maximum rate permitted
          by law, whichever is less. Notwithstanding, if Vendor disputes any
          invoiced fees or charges, Vendor shall pay the entire invoice within
          the timeframe set forth herein and shall identify such dispute in
          writing within sixty (60) days from the date of invoice. GI shall
          investigate such dispute, and if GI determines that such dispute is
          valid, GI shall credit Vendor in the amount of the dispute found to be
          valid.

     D.   GI reserves the right to increase or decrease the charge for any
          service provided pursuant to this Agreement under thirty (30) days
          prior written notice to Vendor. Among other things, this includes the
          right to introduce charges for existing or new services provided
          pursuant to this Agreement and the right to change the method by which
          charges are calculated or assessed.

5.   TERM
     ----

     This Agreement shall commence on August 1, 1998 (the "Commencement Date")
     and, subject to the provisions of this Article, shall continue in full
     force and effect for fifteen (15) months from the Commencement Date. Prior
     to the end of such fifteen month term, the parties shall re-evaluate the
     relationship between the parties to determine the feasibility of extending
     this Agreement or negotiate a new agreement.

6.   PROMOTION, ADVERTISING AND PUBLICITY

     GI and Vendor, from time to time, may promote and advertise the services
     provided for under this Agreement in accordance with programs developed in
     cooperation with each other. Promotions under this Agreement relating to
     Vendor and its services, which include, but are not limited to, the use of
     Vendor's trademarks, service marks, or logos, shall be subject to prior
     written approval of Vendor. Promotions under this Agreement relating to GI
     and its services, which include, but are not limited to, the use of GI's
     trademarks, service marks, or logos, shall be made only upon written
     approval of GI.

7.   SUBSCRIBER LISTING
     ------------------

     Vendor agrees that any GS listing which may be provided to Vendor, at GI's
     discretion and upon the payment of its prevailing rates, is proprietary to
     and is the trade secret of GI, and Vendor shall treat such listing as
     confidential. Any such listing is deemed to be confidential information
     subject to the provisions of Article 14. Vendor shall permit only those of
     its officers, directors, agents and employees with a need to know to have
     access to the listing in the performance of their duties under this
     Agreement, and to take all reasonable measures necessary to ensure that its
     officers, directors, agents and employees are informed of and comply with
     these confidentiality requirements.

          GI), now or hereafter imposed by any local or foreign taxing
          authority, or governmental agency or other similar bodies arising out
          of or in connection with this Agreement. Vendor shall reimburse GI for
          all such taxes, fees and charges within thirty (30) days of receipt of
          GI's invoice therefor. Notwithstanding the foregoing Vendor shall not
          be responsible for any taxes payable or based on GI's net income.

          in advance by the parties hereto, GI shall be responsible for the
          filing of all personal property tax returns and shall pay all taxes

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

     A.   Except in any proceeding to enforce any of the provisions of this

          consent of the other party (the "Owner"), publicize or disclose to any

     B.   If either party is served with a subpoena or other legal process
          requiring the production or disclosure of any Confidential
          Information, then that party, before complying, shall immediately
          notify the Owner and shall use its best efforts to permit the Owner a
          reasonable period of time to intervene and contest disclosure or
          production.

16.  INDEPENDENT CONTRACTORS
     -----------------------

     This Agreement is not intended to and shall not be construed to create or
     establish any agency, partnership or joint venture relationship between the
     parties hereto.

17.  TERMINATION FOR CAUSE
     ---------------------

     A.   If either party (the "Defaulting Party") becomes insolvent, if the
          other party (the "Insecure Party") has evidence that the Defaulting
          Party is not paying its bills when due without just cause; if the
          Defaulting Party takes any step leading to its cessation as a going
          concern, or if the Defaulting Party either causes or suspends
          operations for reasons other than a strike, then the Insecure Party
          may immediately

<PAGE>

          terminate this Agreement on notice to the Defaulting Party unless the
          Defaulting Party immediately gives adequate assurance of the future
          performance of this Agreement by establishing an irrevocable letter of
          credit -- issued by a U.S. bank acceptable to the Insecure Party, on
          terms and conditions acceptable to the Insecure Party, and in an
          amount sufficient to cover all amounts potentially due from the
          Defaulting Party under this Agreement -- that may be drawn upon by the
          Insecure Party if the Defaulting Party does not fulfill its
          obligations under this Agreement in a timely manner.

     B.   If bankruptcy proceedings are commenced with respect to either party
          (the "Bankrupt") and if this Agreement has not otherwise terminated,
          then the other party (the "Other Party") may suspend all further
          performance of this Agreement until the Bankrupt assumes or rejects
          this Agreement pursuant to Section 365 of the Bankruptcy Code or any
          similar or successor provision. Any such suspension of further
          performance by the Other Party pending the Bankrupt's assumption or
          rejection shall not be a breach of this Agreement and shall not affect
          the Other Party's right to pursue or enforce any of its rights under
          this Agreement or otherwise.

     C.   If either party (the "Defaulting Party") fails to observe or perform
          any of its obligations under this Agreement, and such failure
          continues for a period of thirty (30) days after written notice to the
          Defaulting Party by the other party thereof (except in the case of any
          payments due, where the period to cure such nonpayment shall be five
          (5) days after notice), then, without prejudice to any other rights or
          remedies the other party may have, this Agreement shall terminate
          without further notice as of the expiration date of such notice
          period. Notwithstanding anything to the contrary herein, in the event
          Vendor is the Defaulting Party, then GI may, at its sole option and
          without prejudice to any other of its rights or remedies, reduce or
          restrict provision of services provided under the Agreement without
          termination of the Agreement.

18.  NON-WAIVER, POST-TERMINATION RIGHTS
     -----------------------------------

     The right of either party to require strict performance and observance of
     any obligations under this Agreement shall not be affected in any way by
     any previous waiver, forbearance or course of dealing. Exercise by either
     party of its right to under this Agreement shall not affect or impair its
     right to bring suit for any default or breach of this Agreement. All
     obligations of each party that have accrued before termination or that are
     of a continuing nature shall survive termination.

19.  INVALIDITY, SEVERABILITY
     ------------------------

     In the event that any material provision in this Agreement is or is about
     to be prohibited or declared unenforceable in any jurisdiction, or becomes
     impractical or uneconomical to perform as a result of any impending or
     actual change in any applicable law, GI shall, at its option, have the
     right to terminate this Agreement, or to amend, supersede, or delete the
     prohibited, unenforceable, impracticable or uneconomical provision or
     provisions, upon written notice to Vendor. If any provision of this
     Agreement is held invalid or otherwise unenforceable, the enforceability of
     the remaining provisions shall not be impaired thereby.
