examination or other proceeding, action or claim initiated by any Governmental
Entity or by any other party (other than routine claims for benefits) and there
exists no state of facts which after notice or lapse of time or both could
reasonably be expected to give rise to any such investigation, examination or
other proceeding, action or claim or to affect the registration of any
Travelbyus Benefit Plan required to be registered. All contributions or premiums
required to be made by Travelbyus or any of its Subsidiaries under the terms of
a Travelbyus Benefit Plan or by Applicable Laws have been made in a timely
fashion in accordance with Applicable Laws and the terms of a Travelbyus Benefit
Plan, and neither Travelbyus nor any of its Subsidiaries has and, as of the
Effective Time, will have any Liability (other than Liabilities accruing after
the Effective Time) with respect to any of Travelbyus Benefit Plans.
Contributions or premiums will be paid by Travelbyus and its Subsidiaries on an
accrual basis for the period up to the Effective Time even though not otherwise
required to be made until a later date. No amendments have been made to any
Travelbyus Benefit Plan and no improvements to any Travelbyus Benefit Plan have
been promised. No statement, either written or oral, has been made by or on
behalf of Travelbyus or its Subsidiaries that was not in accordance with the
terms of Travelbyus Benefit Plans which would have a Material Adverse Effect.
There have been no withdrawals, applications or transfers of assets from any
Travelbyus Benefit Plan or the trusts or other funding media relating thereto in
violation of Applicable Laws or the terms of Travelbyus Benefit Plans and
neither Travelbyus nor any of its Subsidiaries or any agent thereof has been
negligent, or in breach of any fiduciary obligation, with respect to the
administration of Travelbyus Benefit Plans. Each Travelbyus Benefit Plan is
fully funded or fully insured on both an ongoing and solvency basis. All
employee data necessary to administer each Travelbyus Benefit Plan has been
provided to T24 and is true and correct. No insurance policy or other contract
or agreement affecting Travelbyus Benefit Plans requires or permits a
retroactive increase in premiums or payments due thereunder. The level of
insurance reserves under each insured Travelbyus Benefit Plan is reasonable and
sufficient to provide for all incurred claims. No Travelbyus Benefit Plan
provides benefits to retired employees or to the beneficiaries or dependants of
retired employees. No Travelbyus Benefit Plan is a plan or arrangement to which
more than one employer that is not Travelbyus nor any of its Subsidiaries is
required or permitted to contribute and no Travelbyus Benefit Plan is a multi-
employer plan.

3.13.    Employment-Related Matters - Neither Travelbyus nor any of its
Subsidiaries is a party to any collective bargaining agreement or other contract
or agreement with any labor organization or other representative of any of the
employees of Travelbyus or any of its Subsidiaries nor are any of such contracts
or agreements pending or contemplated. There is no labor strike, dispute,
slowdown, work stoppage or lockout that is pending or to the knowledge of
Travelbyus, threatened against or otherwise affecting Travelbyus or any of its
Subsidiaries and neither Travelbyus nor any of its Subsidiaries has experienced
the same. Except as set forth in section 3.13 of the Travelbyus Disclosure
Schedule neither Travelbyus nor any of its Subsidiaries has closed any plant or
facility, effectuated any layoffs of employees or implemented any early
retirement or separation program at any time from or after December 31, 1999 nor
<PAGE>

                                     -21-

has Travelbyus or any of its Subsidiaries planned or announced any such action
or program for the future with respect to which Travelbyus or any of its
Subsidiaries may have any liability. All salaries, wages, vacation pay, bonuses,
commissions and other compensation payable by Travelbyus or any of its
Subsidiaries to their respective employees before the date hereof have been paid
or accrued in all material respects as of the date hereof. No Person has
asserted any claim or to the knowledge of Travelbyus, has any reasonable basis
to assert any valid claim against Travelbyus or any of its Subsidiaries that
either the continued employment by or association with Travelbyus or any of its
Subsidiaries of any of the current officers or employees of or consultants to
Travelbyus or any of its Subsidiaries contravenes any agreements or Applicable
Laws relating to unfair competition, trade secrets or proprietary information.
Closing will not result in the payment, vesting or acceleration of any benefit,
payment or amount under any of Travelbyus Benefit Plans.

3.14.    Environmental

3.14.1.  Environmental Laws - Travelbyus and its Subsidiaries are in compliance
in all material respects with all applicable Environmental Laws. Neither

Law. To the knowledge of Travelbyus there are no circumstances that may prevent
or interfere with compliance in the future with all applicable Environmental
Laws.

3.14.2.  Environmental Claims - There is no Environmental Claim pending or to
the knowledge of Travelbyus, threatened against or involving Travelbyus or any
of its Subsidiaries or against any Person whose liability for any Environmental

either contractually or by operation of law that if existed, would cause a
Material Adverse Effect.

3.15.1.  Title - Travelbyus and its Subsidiaries have good and marketable title
to all of the tangible assets shown on the Travelbyus Balance Sheet, in each

in a manner consistent with past practice and not material in amount; (b)

recent consolidated financial statements filed by Travelbyus with the
Commissions; (c) Permitted Encumbrances; and (d) Encumbrances set forth in

sections (a) through (d) individually or in the aggregate, would result in a
Material Adverse Effect.

any real property.

3.16.2. Travelbyus Leases - Section 3.16.2 of the Travelbyus Disclosure Schedule

Schedule). Travelbyus Leases grant to Travelbyus or its Subsidiaries leasehold
estates free and clear of all Encumbrances except Permitted Encumbrances.
Travelbyus Leases are in full force and effect and are binding and enforceable
against each of the parties thereto in accordance with their respective terms.
Neither Travelbyus nor any of its Subsidiaries nor to the knowledge of
Travelbyus, any other party to a Travelbyus Lease is in material Violation of
any Travelbyus Lease nor are there any facts or circumstances that would
reasonably indicate that Travelbyus or any of its Subsidiaries is likely to be
in material Violation of any Travelbyus Lease. Section 3.16.2 of the Travelbyus
Disclosure Schedule correctly identifies each Travelbyus Lease that requires the
consent of any Person in connection with the transactions contemplated hereby.
No material construction, alteration or other leasehold improvement work with
respect to the real property covered by any of Travelbyus Leases remains to be
paid for or to be performed by Travelbyus or any of its Subsidiaries.

3.16.3. Condition - All buildings, structures and fixtures or parts thereof used

intangible proprietary information or material that are used in the business of
Travelbyus and its Subsidiaries (the "Travelbyus Proprietary Rights"), free and
clear of any and all Encumbrances. To the knowledge of Travelbyus, there is no
reason why Travelbyus and its Subsidiaries will not be able to
<PAGE>

                                     -23-

continue to own or have perpetual, fully paid, worldwide rights to use all

respective business as currently conducted and as currently proposed to be
conducted without any infringement or conflict with the rights of others. Except
as set forth in section 3.17.1 of the Travelbyus Disclosure Schedule all of the

or any of its Subsidiaries to be in violation or in default under any material
license, sublicense or agreement nor will entitle any other party to any such
license, sublicense or agreement to terminate or modify such license, sublicense
or agreement.

performance by Travelbyus of its obligations hereunder and the consummation by

the Transaction including without limitation the making of the T24 Loan
Commitment will not cause T24 or any of its Subsidiaries to be in violation or

other party to any material license, sublicense or agreement to terminate or
modify such license, sublicense or agreement.

pending, have been asserted or to the knowledge of T24 are threatened by any
Person nor to the knowledge of T24 are there any valid grounds for any bona fide
claims; (a) to the effect that the development, sale, licensing or use of any of
the products of T24 and its Subsidiaries as now developed, sold, licensed or
used or as proposed for development, sale, licensing or use by T24 and its
Subsidiaries infringes on any patent, industrial design, trademark, trade name,
service mark, copyright, trade secret, website or domain name or other
proprietary right of any Person; (b) against the use by T24 or any of its
Subsidiaries of any patents, industrial designs, trademarks, trade names,

consultant of T24 or any of its Subsidiaries is in violation of any term of any

provision of any Contract to which T24 or any of its Subsidiaries is a party or
by which it, any of its Subsidiaries or any of their respective material assets
or properties is bound or which is applicable to it, any of its Subsidiaries or
any of their respective material assets or properties, except for such
Violations which, individually or in the aggregate, would not result in a

Except as set forth in section 4.19 of the T24 Disclosure Schedule, all of the
T24 Insurance Contracts are in full force and effect with no default thereunder
by T24 or any of its Subsidiaries which could permit the insurer to deny payment
of claims thereunder. The execution and delivery by T24 of this Agreement, the
performance by T24 of its obligations hereunder and the consummation by T24 of
the Transactions including without limitation the making of the T24 Loan
Commitment and thereby will not cause T24 or any of its Subsidiaries to be in
Violation of any T24 Insurance Contracts nor entitle any other party thereto to
terminate or modify a T24 Insurance Contract. Neither T24 nor any of its
Subsidiaries has received notice from any of their respective insurance carriers
that any insurance premiums will be materially increased in the future or that
any insurance coverage provided under the T24 Insurance Contracts will not be

material supplier,
<PAGE>

                                     -42-

distributor or customer of T24 or any of its Subsidiaries has cancelled or
otherwise adversely modified its relationship with T24 or any of its
Subsidiaries, and to the knowledge of T24, no supplier, distributor or customer
of T24 or any of its Subsidiaries has any intention to do so. To the knowledge
of T24, none of the execution and delivery by T24 of this Agreement, the
performance by T24 of its obligations hereunder and the consummation by T24 of
the Transaction including without limitation the making of the T24 Loan
Commitment will materially adversely affect any such relationship.

4.22. Products - Each product sold, leased, licensed or delivered by T24 or any
of its Subsidiaries has been in material conformity with all applicable
contractual commitments.

4.23. No Broker's or Finder's Fees - None of T24, any of its Subsidiaries and
their respective directors, officers, employees and agents has employed any
broker, finder, financial advisor or intermediary or has paid or incurred any
liability for any fee or commission to any broker, finder, financial advisor or
intermediary in connection with this Agreement except for contracts with Von
Weichs and Partner GmbH and CMF AG.

4.24. Full Disclosure - This Agreement does not contain any untrue statement of
a material fact or omit to state a material fact necessary to make the
statements contained herein not false or misleading. To the knowledge of T24
there is no fact existing on the date hereof that T24 has not disclosed to
Travelbyus in writing that could result in a Material Adverse Effect.

5.1   Non-Waiver - No investigations made by or on behalf of Travelbyus or T24

otherwise affecting any representation or warranty made by the Travelbyus or
T24, as applicable, in or pursuant to this Agreement. No waiver of any condition
or other provision, in whole or in part, shall constitute a waiver of any other
condition or provision (whether or not similar) nor shall such waiver constitute
a continuing waiver unless otherwise expressly provided. However, the
circumstances set forth in the Travelbyus and the T24 Disclosure Schedules are,
to the extent they have been duly disclosed, deemed known to the respective
other Party; the Agreement is concluded with imputed knowledge of such
circumstances and therefore no claims may be raised in this respect.

contained in this Agreement on the part of each of the Parties shall survive the
Closing, the execution and delivery under this Agreement of any share or
security transfer instruments or other documents of title to any of the

           Corporation for any particular taxation year ended on or prior to the
           Closing Date; and

     (v)   all other representations and warranties shall survive for a period
           of three years from the Closing Date.

8.3  Notification of and Participation in Claims - No claim for indemnification
will arise until notice thereof is given to T24 or Travelbyus , as the case may
be. Such notice shall be sent within a reasonable time following the
determination by Travelbyus or T24, as applicable, that a claim for indemnity
exists. If any legal proceedings shall be instituted or any claim or demand is
asserted by any third Person in respect of which T24 or Travelbyus , as
applicable, may have an obligation to indemnify Travelbyus , or T24, as the case
may be, Travelbyus or T24, as the case may be, shall give or cause to be given
to T24 or Travelbyus , as the case may be, written notice thereof and such Party
shall have the right, at its option and expense, to be present at the defence of
such proceedings, claim or demand, but not to control the defence, negotiation
or settlement thereof, which control shall at all times rest with Travelbyus or
T24, as the case may be, unless T24 or Travelbyus , as the case may be,
irrevocably acknowledges full and complete responsibility for indemnification of
Travelbyus or T24, as the case may be, in which case T24 or Travelbyus , as the
case may be, may assume such control through counsel of its choice provided
however that no settlement shall be entered into without Travelbyus 's written
consent or the Vendor's written consent, as the case may be, which shall not be
unreasonably withheld. The Parties shall co-operate fully with each other in
connection with the defence, negotiation or settlement of any such third Person
legal proceeding, claim or demand by reason of a breach of the provisions of
section 11.2.

8.4  De Minimis Threshold - Travelbyus and T24 shall be liable for claims for
indemnification only in the event that the aggregate amount of such claims
exceeds US$1,000,000 (United Sates Dollar one million), respectively. In case
the aggregate

amount of such damages exceeds the aforementioned threshold, Travelbyus and T24,
respectively, shall be liable for the entire amount of the claims.

8.5  Limitation of Remedies - The claims for indemnification and resulting
remedies shall not include the claim to rescind or cancel or in any other way
withdraw from this Agreement. Otherwise, the rights and remedies of Travelbyus
and T24 arising out of a breach of misrepresentations, warranties or covenants
under this Agreement shall not be limited, unless such limitation is
specifically provided for.
