1   INTRODUCTION

1.1     MANAGER'S SUMMARY

This proposal offers High-Tech Travel Service the state of the art in travel
reservations, an integrated intranet, internet and extranet to run a travel
wholesale operation with transparent interface to all 4 major reservation
systems (Sabre, Apollo, Worldspan, and Amadeus).

Tournet's iRES System is a mature and proven software that not only automates
all aspects of a travel wholesale operation, from reservations, operations to
marketing and accounting. It works for outbound, inbound, and all travel
applications for any number of users.

It has been re-written in a 3-tier architecture for Windows 2000 using MS-SQL 7
and Visual Studio, and it is 100% browser driven. It has an innovative
spreasheet-like data entry scheme and a data-driven rate validation system to
handle complex hotel and airline contracts quickly and efficiently and to
provide on-the-fly tour packaging and pricing at the point of sale.

 This leading edge design has made our Tour Reservations Software the
centerpiece of our proposed standard for a Central Reservations System, CRS, for
holiday bookings on the Internet: a true Leisure Reservation System that is
comprehensive and available to agents, suppliers and wholesalers as well as to
the public and even to travel portals.

This proposal provides High-Tech Travel with a complete automation solution,
including 15 months of maintenance and support, iRES as the internal ResSystem,
TravelSite for the travel agents and their customers, and consumerSite for the
direct sales. Once completed, will be closely integrated with the major online
reservation systems for a tour wholesale and air consolidation operations with
widely dispersed offices.

Tournet also brings relief to the travel industry, pretty soon you'll find use
for the efficiency of a graphical interface based point of sale system, and for
modern and versatile tour packaging techniques and innovative report generation
that places automation in your hands, no more total dependency on the system
developers. You could reduce the time to make a sale and data entry by 90
percent not to mention data maintenance.

Tournet is out there moving thousands of passengers; companies have grown with
it. This proposal shows what we can do for you and how we have made it simple
and risk-free for your company to benefit from over 17 years of development to
get the competitive edge needed on today's sophisticated travel marketplace.

1.2     ABOUT TOURNET SYSTEMS, INC.

Tournet has been developing an infrastructure for a Travel Automation Network
since 1983 and thus established the architecture for a ground-breaking e-network
for the promotion, distribution, sales and operations of leisure travel
products. Adopting to the new e-commerce environment, today's Tournet embraces
the internet as the new business medium. Powered by leading edge database and
graphical user interface (GUI) technology, Microsoft's SQL 7 and Visual Studio
we have rebuilt Tournet as a browser driven Travel Reservation System. This is a
state-of-the-art, comprehensive Reservation System for travel wholesalers
irrespective of their specialization, be it inbound, outbound, consolidation,
cruise, ground or groups. A system sophisticated enough to generate on-the-fly
tour packaging required for effective internet leisure sales.

Provided the proper structure and business platform, the opportunities for this
system is bountiful. Tournet is the logical automation choice for today's travel
groups and consortiums. It boasts the sophistication to power leading travel
portals and become a CRS service and travelSite for hundreds of smaller travel
packagers, wholesalers, agencies and suppliers worldwide. Market conditions are
ripe with major travel distributors of all kinds seeking technologies to drive
sales in the new e-era. No competing product has been designed with the clear
objective of becoming the booking engine for the growing demand for flexible
vacation packaging on the internet. As will be discussed below, we believe that
Tournet's technical advantage is estimated to be two years ahead of any
potential competitor.

1.3     PROJECT SCOPE

To build a web-based travel reservation system for consumers and agents. It will
provide Air, Hotel, Car Rental and Vacation/Tour bookings. The consumer can book
directly or request one of the agents to book for them. Any booking done by the
agents will be done through this proposed system. The system will provide
real-time online booking in a quick and efficient manner.

<PAGE>

2   SYSTEM OVERVIEW

2.1     INTRODUCTION

The system will have two basic types of users and therefore have two travel web
portals, the consumer and the travel agent as follows:

     o   CONSUMER - this person wants to either make a reservation (tickets,
         hotel, car, or vacation package) on-line real-time or be able to
         request it. The request (via e-mail or FAX) goes to one of our member
         agents. The system will be as quick and as user friendly as possible.

     o   TRAVEL AGENCY AGENT/INDEPENDENT AGENT - this is the person who will
         make reservations for the consumers (business or personal). Their
         interface will be very fast and to the point. These agents know the
         system and need to make the reservations fast. Commissions are also
         calculated, stored and reported.

2.2     PHASES

2.2.1    PHASE I

CONSUMER FUNCTIONS

The consumer's site will be slightly different from that of the Agents. It will
be more user friendly, and have the ability to "walk them through" the site. The
existing www.extus.com will be used as a basis of the new system. From a
functional view, the following will need to be addressed on the consumer site:

     o   TICKETING (AIR) - this will be basically the same as other major travel
         sites on the web today.
     o   EXPRESS AIR RESERVATIONS - Ability to do a quick lookup from the main
         page.
     o   HOTEL BOOKING - based on a profile or nearest X-star hotel to the
         destination airport.
     o   CAN RENTAL BOOKING - based on a profile or cheapest rate at the
         destination airport.
     o   VACATION BOOKING - based on available CRS packages.
     o   MEMBER PROFILE MAINTENANCE - all the information about the consumer,
         preferences, mileage programs, address and billing info.
     o   SAVE TRIPS/PLANS FOR LATER UPDATES - this would provide people a way to
         save issued and non-issued vacation/ticket reservations. The issued
         reservations could be modified, while the non-issued ones can be held
         and be updateable while they decide.
     o   MULTI-LANGUAGE SUPPORT - ability to build different sites with current
         software.

TRAVEL AGENCY/INDEPENDENT AGENT FUNCTIONS

The Agent on the other hand needs their version of the site to be quick and to
the point. We might consider using the same GUI and methods such as existing CRS
systems. The lists of functions we'll need to provide to the Agents are:

     o   TICKETING (AIR) - via a CRS, in a display format that is similar to the
         interface they currently use.
     o   VACATION BOOKING - most likely they will be able to use on-line (or
         paper) brochures along with our on-line pricing guides and make the
         reservation through our CRS interface.
     o   HOTEL BOOKING - based on a profile or nearest x-star hotel to the
         destination airport.
     o   CAN RENTAL BOOKING - based on a profile or cheapest fare at the
         destination airport.
     o   VACATION BOOKING - based on available CRS packages.
     o   HOLD TRIP INFORMATION ON THE SYSTEM - the Agent can enter information
         into a "reservation" record as it become available. This will help in
         collecting the consumer information (the form data will be imported
         into this record), not only for the reservation but also for agent
         "client management lists". We will keep the data on our system only,
         not locally (don't want to give this to the agent).

2.2.2    PHASE II

In this phase we will capture the vacation/tour booking and "nice to have" items
for both the consumer and agent as follows:
     o   VACATION BOOKING - we will have many different vacation tours (up to 10
         for Phase II), that a consumer can peruse and book via the site. They
         will also be able to request a vacation from one of the member agents
         by simply filling out a form on-line. They will be asked questions
         relating to who, when, and where they will be going. This will be
         similar to what they would have done had they gone to a local travel
         agent.
     o   ALLOW TOUR BOOKINGS - be able to update our databases with the tour
         operators pricing and content.
     o   WEATHER REPORTS -A link.
     o   AIRPORT LAYOUTS - for connecting flights.
     o   DESTINATION CITY INFO - A link.
     o   TRAVEL TIPS/SECURITY BULLETINS/ETC.- a link.
     o   NEWSLETTER - various types based on profile
     o   BIOMETRICS (FINGERPRINTING) - used by the agents to log into the
         system.
     o   CHEAPEST FARES - The system will have the capability of determining
         which CRS to use based on which has the cheapest fares.
     o   ROUND-ROBIN - the system will "round-robin" the requests such that all
         agents get their chance at potential clients.
     o   AGENT CALL - Allow the consumer to call the agent directly with a
         tracking "ticket number"

<PAGE>

2.3     SYSTEM HIGHLIGHTS

     o   Hours of operation will be 7x24.
     o   There will be a customer call center for agent and consumer support
         calls. (HTT responsibility)
     o   Application will be hosted by Tournet systems, Inc. in our NYC hosting
         center.
     o   Login control for agent - they will use the same information as the
         consumer, but in a different format.
     o   Consumer sign-in ONLY when requested - allow flight info and pricing
         before sign-in.
     o   Get the cheapest fare possible by allowing to & from dates for
         departure/return and possible multiple legs.
     o   Allow search & book functions - air, hotel, car rental and vacation
         packages
     o   Allow consumer to request a vacation by filling out an on-line form.
         The information on the form will be sent via e-mail to the next
         available (round-robin) agent.
     o   Independents will be able to get full commission; agents of a travel
         agency will get partial (this is actually per their agreement with
         their agency).
     o   Have a fully functional commission reporting system
     o   Perform all back-end functions such as reporting, database connectivity
         and profile maintenance. o Have calendars available with holidays noted

Company shall in no event be required to qualify generally to do business as a
foreign corporation or as a dealer in any jurisdiction where it is not at the
time so qualified or to execute or file a general consent to service of process

              (a)  Parent will, without limitation as to time, indemnify and
hold harmless, to the full extent permitted by law, each Holder, each of its
officers and directors and partners, and each person controlling such Holder
within the meaning of Section 15 of the Securities Act, with respect to which
registration, qualification or compliance has been effected pursuant to this
Section 1, and each underwriter, if any, and each person who controls any
---------
underwriter within the meaning of Section 15 of the Securities Act or the
Exchange Act, against all expenses, claims, losses, damages or liabilities (or
actions in respect thereof), including any of the foregoing incurred in
settlement of any litigation, commenced or threatened, arising out of or based
on any of the following statements, omissions or violations, or allegations
thereof (any of which, a "Violation"): (i) any untrue statement (or alleged
                          ---------

<PAGE>

statement, prospectus, offering circular or other document, or any amendment or
supplement thereto, incident to any such registration, qualification or
compliance, (ii) any omission (or alleged omission) to state therein a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances in which they were made, not misleading or (iii)
any violation by Parent of the Securities Act, the Exchange Act, state
securities law or any rule or regulation promulgated under such laws applicable
to Parent in connection with any such registration, qualification or compliance,
and within a reasonable period Parent will reimburse each such Holder, each of
its officers and directors, and each person controlling such Holder, each such
underwriter and each person who controls any such underwriter, for any legal and
any other expenses reasonably incurred in connection with investigating,
preparing or defending any such claim, loss, damage, liability or action;
provided that Parent will not be liable in any such case to the extent that any
such claim, loss, damage, liability or expense arises out of or is based on (x)
any untrue statement or omission or alleged untrue statement or omission, made
in reliance upon and in conformity with written information furnished by the
Holder to Parent for use in the Registration Statement or (y) a material
misstatement or omission of fact contained in any preliminary prospectus if a
final, amended or supplemental prospectus which corrects such omission or
misstatement is delivered by Parent to such person at or prior to the written
confirmation of the sale giving rise to the Violation or alleged Violation.

              (b)  Each Holder will, if Registrable Securities held by such
Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify Parent, each of its
directors and officers, each underwriter, if any, of Parent's securities covered
by such a registration statement, each person who controls Parent or such
underwriter within the meaning of Section 15 of the Securities Act, and each
other such Holder, each of its officers and directors and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on a Violation, and within a reasonable period
will reimburse Parent, such Holders, such directors, officers, persons,
underwriters or control persons for any legal or any other expenses reasonably
incurred in connection with investigating or defending any such claim, loss,
damage, liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished by the Holder to Parent for use in the Registration Statement.
Notwithstanding the foregoing, the liability of each Holder under this
subsection (b) shall be limited in an amount equal to the gross proceeds before
expenses and commissions to each Holder received for the shares sold by such
Holder, unless such liability arises out of or is based on willful misconduct by
such Holder.

              (c)  Each party entitled to indemnification under this Section 1.6
                                                                     -----------
(the "Indemnified Party") shall give notice to the party required to provide
      -----------------
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
                      ------------------
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any

                                      -5-
<PAGE>

Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section 1 unless the failure to
                                                 ---------
give such notice is materially prejudicial to an Indemnifying Party's ability to
defend such action and provided further, that the Indemnifying Party shall not
assume the defense for matters as to which there is a conflict of interest or
separate and different defenses. No Indemnifying Party, in the defense of any
such claim or litigation, shall, except with the consent of each Indemnified
Party, consent to entry of any judgment or enter into any settlement which does
not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party of a release from all liability in respect
to such claim or litigation.
