          attorney duly executed in blank.

                                   ARTICLE 3

                     PURCHASE PRICE AND PAYMENT ADJUSTMENT

3.1  The aggregate purchase price for the Purchased Shares shall be satisfied
and paid on Closing by Travelbyus by way of the issuance of 4,000,000 fully paid
and non-assessable common shares in the capital of Travelbyus (the "Travelbyus
Shares") to the Sellers in the numbers set forth on Schedule 3.1 attached hereto
and forming a part hereof. As provided in the LOI, the Deposit shall be retained
by SiteRabbit to be used as and by way of working capital.

3.2  Purchase Price Adjustments - Travelbyus agrees that, subject to requisite
regulatory and stock exchange approvals, the number of the Travelbyus Shares
(from 4,000,000 common shares) shall be adjusted (the "Adjustment") on the
earlier of (the "Reference Date"): (i) December 15, 2000; and (ii) the first
NASDAQ trading date that is ninety days after the SEC declares effective the
Form S-4 registration statement of Aviation (SEC filing number 333-40352).  The
Travelbyus Shares shall be adjusted if (and only if) the average of the daily
per share closing price of the common shares of Travelbyus quoted on NASDAQ for
the five trading days prior to and the five trading days after the Reference
Date (the "Average Daily Closing Price") is less than US$2.50 per share.
Travelbyus will use its best efforts to effect the adjustment within fifteen
trading days after the Reference Date and will use its best efforts to ensure
that additional common shares in the capital of Travelbyus (the "Additional
Shares") are issued to the Sellers pro rata (in accordance with the percentages
set forth in Schedule 3.1) so that the aggregate value of the Travelbyus Shares
and the Additional Shares, equals US$10 million as at the Reference Date.  For
greater certainty and without limitation, if as of the Reference Date, the
common shares of Travelbyus are not listed and quoted on NASDAQ but are listed
and quoted on another foreign stock exchange, then the Average Daily Closing
Price shall be calculated by reference to the closing price on such exchange and
shall be adjusted for currency exchange rates.  Notwithstanding the foregoing,
in no event shall Travelbyus be obligated to issue to the Sellers greater than
an additional 4,000,000 Additional Shares as part of the Adjustment.  If at any
time prior to the issuance of the Additional Shares to the Sellers:

     (a)  the outstanding Travelbyus Shares are subdivided or are consolidated
          into a greater or lesser number of Travelbyus Shares, respectively;

     (b)  the Travelbyus Shares are reclassified, exchanged for or converted
          into other shares, securities or property;

     (c)  a stock dividend has been declared and paid on the Travelbyus Shares;

     (d)  there has been an amalgamation, merger, consolidation or other
          reorganization affecting Travelbyus; or

     (e)  there has been a transfer of all or substantially all of the
          undertaking or
<PAGE>

                                      -13-

          assets of Travelbyus to another corporation or entity,

(any of such events being referred to in this paragraph 3.2 as a "Change"), then
the Sellers, after the effective date of the Change shall be entitled to receive
and shall accept and Travelbyus shall deliver in accordance with this Agreement,
in lieu of the number of Additional Shares deliverable prior to the effective
date, the aggregate number and kind of Additional Shares or other securities or
amount of property which the Sellers would have been entitled to as a result of
the Change if, on the effective date thereof, the Sellers had been the
registered holder of the number of Additional Shares the Sellers would have
received had they received the Additional Shares immediately before the
effective date of the Change.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE LISTED ON THE TORONTO STOCK
EXCHANGE; HOWEVER, THE SAID SECURITIES CAN NOT BE TRADED THROUGH THE FACILITIES
OF SUCH EXCHANGE SINCE THEY ARE NOT FREELY TRADEABLE, AND CONSEQUENTLY ANY

recommending work or repairs in respect of any of the buildings, improvements or
other structures constructed on the Real Property and the premises subject to
the Real Property Leases or any installations therein or of any current non-
compliance with applicable statutes and regulations or building and zoning by-

a lien under any construction lien legislation in any applicable jurisdiction
for such work performed by or on behalf of either of the Targets and the
Management Sellers have no knowledge of any proposed or pending change to any
zoning affecting the Real Property. The Management Sellers have no knowledge of
any expropriation or condemnation or similar proceeding pending or threatened
against the Real Property. There are no matters affecting the right, title and
interest of either of the Targets in and to the Real Property, which in the
aggregate or individually, would materially and adversely affect the ability of
each of the Targets to carry on business upon the Real Property.

5.22 Real Property Leases - Schedule 5.22 sets forth a complete list of the
Real Property Leases.  Each of the Real Property Leases is in full force and

clear of all Encumbrances of any nature and kind whatsoever.  There are no
consents necessary as a result of the completion of the Transaction save and
except as set forth in Schedule 5.22.  All payments required to be made by the
Targets pursuant to the Real Property Leases have been duly paid and neither of
the Targets is otherwise in default in meeting its respective obligations under
any of the Real Property Leases.  The Management Sellers have no knowledge that
any of the landlords under each of the Real Property Leases are in default in
meeting any of the material obligations under their respective Real Property
Leases.  Except as detailed on Schedule 5.22, neither of the Targets has any
option, right of first refusal or other contractual right relating to the Real
Property.  To the knowledge of the Management Sellers, no event exists which,
but for the lapse of time or the giving of notice, or both, would constitute
default under any such option, right of first refusal or other contractual right
and to the knowledge of the Management Sellers, no Person is claiming any such
material default or taking any action purportedly based upon any default.  To
the knowledge of the Management Sellers, no event exists which, but for the
passing of time or the giving of notice or both, would constitute a default by
any party to any of the Real Property Leases and no party to any Real Property
Lease is claiming any such default or taking any action purportedly based upon
any such default.  Neither of the Targets has waived or omitted to take any
action in respect of any substantial rights under any of the Real Property
Leases.

Real Property or any other property now or formerly under its respective charge,
management, operation or control have been and are now, in compliance with all

knowledge of the Management Sellers, threatened to revoke or amend any

operations has been or is now the subject of any Remedial Order nor do the
Management Sellers have any knowledge of any investigation or evaluation
commenced as to whether any such Remedial Order is necessary nor has any threat
of any such Remedial Order been made nor do the Management Sellers have
knowledge of any circumstances which could result in the issuance of any such
Remedial Order. Neither of the Targets has ever been prosecuted for or convicted
of any offence under Environmental Laws nor has either of the Targets been found
liable in any proceeding to pay any fine or judgment to any Person as a result

such Laws against either of the Targets.  There are no complaints nor to the
knowledge of the Management Sellers, are there any threatened complaints,
against either of the Targets before any employment standards branch or tribunal
or human rights tribunal.  To the knowledge of the Management Sellers, nothing
has occurred which might lead to a complaint against either of the Targets under
any human rights legislation or employment standards legislation.  There are no
outstanding decisions or settlements or pending settlements under employment
standards legislation which place any obligation upon either of the Targets to
do or refrain from doing any act.  Neither of the Targets has been subject to

respect of salary, wages, bonus or benefits, have been paid or accrued for on

contractors of either of the Targets. There are no outstanding labour tribunal
proceedings of any kind, including any proceedings which could result in
certification of a trade union as bargaining agent for Employees or independent
contractors of the Targets and there have not been any such proceedings within
the last two years. There are no threatened or apparent union organizing
activities involving the Employees or independent contractors of either of the
Targets. There is no strike or lock-out occurring or threatened which affects or
would affect either of the Targets. Neither of the Targets has any unresolved
grievances or pending arbitration cases outstanding. Neither of the Targets has
any serious labour problems that might materially affect the value of the
Targets or that might lead to an interruption of the Business.

5.26 Benefit Plans - Schedule 5.26 sets forth a complete list of all Benefit
Plans.  Current and complete copies of all written Benefit Plans or where oral,
written summaries of the material terms thereof, have been provided or made
available to  Travelbyus together with current and complete copies of all
documents relating to the Benefit Plans, including without limitation, as
applicable; (i) all documents establishing, creating or amending any Benefit
Plan; (ii) all trust agreements, funding agreements, insurance contracts and
investment management agreements; (iii) all financial statements and accounting
statements and reports and investment reports for each of the last three years

most recent actuarial reports in relation to each such Benefit Plan; (iv) all
reports, returns, filings and material correspondence with any applicable
regulatory authority in the last three years; and (v) all booklets, summaries or
manuals prepared for or circulated to and written communications of a general
nature to Employees concerning any Benefit Plan.  Each Benefit Plan is, and has
been, established, registered, qualified and administered and invested in
compliance with; (i) the terms thereof; and (ii) all applicable Laws.  Neither
of the Targets has received, in the last three years, notice from any Person
questioning or challenging such compliance and the Management Sellers have no
knowledge of any such notice from any Person questioning or challenging such
compliance beyond the last three years.  All obligations under the Benefit Plans
(whether pursuant to the terms thereof or applicable Laws) have been satisfied
and there are no outstanding defaults or violations thereunder by each of the
Targets nor do the Management Sellers have any knowledge of any default or
violation by any other party to any Benefit Plan.  There have been no
amendments, modifications or restatements of any Benefit Plan made or any
improvements in benefits promised under the Benefit Plans that have not been
disclosed to Travelbyus.  All contributions or premiums required to be paid to
or in respect of each Benefit Plan have been paid in a timely fashion in
accordance with the terms thereof and all applicable Laws.  No Taxes, penalties
or fees are owing or exigible under any Benefit Plan.  There is no Claim pending
or threatened involving any Benefit Plan or its assets and no facts exist which
could reasonably be expected to give rise to any such Claim.  No event has
occurred respecting any Benefit Plan which would entitle any Person (without the
consent of either of the Targets) to wind-up or terminate any Benefit Plan, in
whole or in part, or which could reasonably be expected to adversely affect the
tax status thereof or require any penalty taxes to be paid under any applicable
laws.  There are no going concern unfunded actuarial liabilities, past service
unfunded liabilities or solvency deficiencies respecting any of the Benefit
Plans.  No material changes have occurred in respect of any Benefit Plan since
the date of the most recent financial or accounting
<PAGE>

                                      -25-

report issued in connection with any Benefit Plan which could reasonably be
expected to adversely affect the report (including rendering it misleading in
any material respect). All employer contribution or premium holidays that have
been taken under any Benefit Plan have been permitted by the terms of the
relevant Benefit Plan and have been in accordance with applicable Laws. There
have been no improper withdrawals or transfers of assets from any Benefit Plan.
All employee data necessary to administer each Benefit Plan is in the possession
of the Targets and is complete, correct and in a form which is sufficient for
the proper administration of the Benefit Plans and none of the Benefit Plans
provide benefits to retired Employees or to the beneficiaries or dependants of
retired Employees. None of the Benefit Plans require or permit a retroactive
increase in premiums or payments and the level of insurance reserves, if any,
under any insured Benefit Plan is reasonable and sufficient to provide for all
incurred but unreported claims. The consummation of the Transaction shall not
constitute an event under any Benefit Plan that shall or may result; (i) in any
acceleration of, or vesting of, or increase in benefits with respect to any
Employee or former Employee; or (ii) in any acceleration of or increase in the
funding requirements of any Benefit Plan.

5.27 Insurance - Each of the Targets maintains such policies of insurance,
issued by responsible insurers, as are appropriate to its respective operations,
property and assets, in such amounts and against such risks as are customarily
carried and insured against by owners of comparable businesses, properties and
assets.  All such policies of insurance are in full force and effect and neither
of the Targets is in default as to the payment of premiums or otherwise under
the terms of any such policy.  Schedule 5.27 sets forth a complete list of all
policies of insurance which either of the Targets maintains and the particulars
of such policies including the name of the insurer, the risk insured against,

of the parties to such Contracts.  Except as noted on Schedule 5.28 none of the
Material Contracts include provisions requiring consent to a change of control
of the Targets.  Current and complete copies of the Material Contracts have been
delivered to Travelbyus.  There are no current or pending negotiations with
respect to the renewal, repudiation or amendment of any such agreement, plan or
policy.

time and manner required by law including any extensions of time to file) all
federal and state income Tax Returns and election forms and the Tax Returns of
any other jurisdiction required to be filed and all such returns and forms have
been completed accurately and correctly in all respects.  As of Closing, the
Targets will have paid all Taxes (including
<PAGE>

                                      -26-

with respect to the payment of any Tax, governmental charge or deficiency by the
Targets nor are there any examination, actions, suits, proceedings,
investigations or claims now threatened or pending against the Targets in
respect of, or discussions under way with any governmental authority relating
to, any such Tax or governmental charge or deficiency.

Neither of the Targets has:

(i)   acquired or had the use of any property from a Person with whom either of
      the Targets was not dealing at arm's length other than at fair market
      value;

(ii)  disposed of any property to a Person with whom either of the Targets was
      not dealing at arm's length for proceeds less than the fair market value

      losses were incurred and any non-capital losses which either of the

transaction.  The schedules attached to the corporate income tax returns by each
of the Targets for its respective taxation years ended June 30, 1998 and 1999,
reflect and disclose all transactions to which each of the Targets was a party

                                INDEMNIFICATION

10.1 Indemnification by the Management Sellers - The Management Sellers agree
to indemnify and save harmless Travelbyus without duplication on an after-tax
basis from and against all losses suffered or incurred by Travelbyus from and
after Closing as a result of or arising directly or indirectly out of or in
connection with:

     (a) any breach by the Management Sellers of or any inaccuracy of any of the
         representations and warranties of the Management Sellers set out in
         Article 4 of this Agreement, on a several basis as set out in Article 4
         of this Agreement;
<PAGE>

                                      -34-

     (b) any breach by the Management Sellers of or any inaccuracy of any of the
         representations and warranties of the Management Sellers set out in
         Article 5 of this Agreement, on a joint and several basis as set out in
         Article 5 of this Agreement;

     (c) any breach or non-performance by the Management Sellers of any
         covenants to be performed by the Management Sellers under this
         Agreement; and

     (d) except to the extent Taxes are reserved for on the SiteRabbit Financial
         Statements, (i) for any and all Taxes with respect to all taxation
         years of the Targets ending on or prior to June 30, 2000, except and
         excluding any and all Taxes that may arise from or result from the
         Transaction; (ii) all Taxes allocated to the Management Sellers
         pursuant hereto; and (iii) any losses or expenses with respect to all
         taxation years of the Targets ending on or prior to June 30, 2000,
         arising out of or incidental to the imposition, assessment or assertion
         of any such Taxes, including those incurred in connection with the
         assertion or defense of any claim or assessment for such Taxes except

         year ending on or prior to June 30, 2000 (which the Management Sellers

         promptly inform the Management Sellers and the Management Sellers shall
         have the right to control, at their own cost and expense any resulting

         assessment or dispute to the extent such proceedings or determinations
         affect the amount of Taxes for which the Management Sellers are liable
         under this Agreement.  For greater certainty and without limitation,
         each of Travelbyus and the Management Sellers shall provide the other
         Party with such assistance as may reasonably be requested by either of
         them in connection with the preparation of any Tax Return, any audit or
         other examination with the preparation of any Tax Return, any audit or
         other examination by any taxing authority or any judicial or
         administrative proceedings relating to liability for Taxes and each
         will retain and provide the other Party with any records or information
         which may be relevant to such Tax Return, audit or examination,
         proceedings or determination.

10.2 Indemnification by Sellers - The Sellers agree to indemnify and save
harmless Travelbyus without duplication on an after-tax basis from and against

directly or indirectly out of or in connection with:

     (a)  any breach by the Sellers of or any inaccuracy of any of the
          representations and warranties of the Sellers set out in Article 4 of
          this Agreement, on a several basis as set out in Article 4 of this
          Agreement; and

          performed by the Sellers under this Agreement.

10.3 Indemnification Limitations - Sellers will have liability (for
indemnification or otherwise) for any losses suffered or incurred by Travelbyus
from and after Closing with respect to the matters described in this Section 10
only for an amount up to the closing price of the Travelbyus Shares on the
Closing Date.  Each of the Sellers will have liability only for his, her or its
pro-rata amount of Travelbyus Shares received on the Closing Date.

10.4 Indemnification by Travelbyus - Travelbyus agrees to indemnify and save
harmless the Sellers on an after-tax basis from and against all losses suffered
or incurred by the Sellers from and after Closing as a result of or arising
directly or indirectly out of or in connection with:

     (a) any breach by Travelbyus of or any inaccuracy of any of the
         representations and warranties of Travelbyus set out in Article 6 of
         this Agreement; and

     (b) any breach or non-performance by Travelbyus of any covenants to be
         performed by Travelbyus under this Agreement.

10.5 Notification of and Participation in Claims -  No claim for
indemnification shall arise until notice thereof is given to the Sellers or
Travelbyus, as the case may be.  Such notice shall be sent within a reasonable
time following the determination by Travelbyus or the Sellers, 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 the
Sellers or Travelbyus, as applicable, may have an obligation to indemnify
Travelbyus or the Sellers, as the case may be, Travelbyus or the Sellers, as the
case may be, shall give or cause to be given to the Sellers 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 the Sellers, as the
case may be, unless the Sellers or Travelbyus, as the case may be, irrevocably
acknowledges full and complete responsibility for indemnification of Travelbyus
or the Sellers, as the case may be, in which case the  Sellers or Travelbyus, as
the case may be, may assume such control through counsel of their respective
choice provided however that no settlement shall be entered into without
Travelbyus' written consent or the Sellers' written consent, as the case may be,
which shall not be unreasonably withheld.  The Parties shall co-operate
<PAGE>

                                      -36-

fully with each other in connection with the defence, negotiation or settlement
of any such third Person legal proceeding, claim or demand.

following the termination thereof (with respect to J. Michael London) and, with
respect to each of the other Sellers, they shall not for a period ending two
years:

     (a)  directly or indirectly solicit, interfere with or endeavour to direct
          or entice away from either of the Targets, any person, firm or company
          who is or has within the preceding year been a customer, client or
          otherwise in the habit of dealing with either of the Targets; or

     (b)  interfere with, entice away or otherwise attempt to induce the
          termination of employment of any employee of either of the Targets.

11.2 Non-Competition Covenant.  The Sellers do hereby severally covenant and
     ------------------------
agree with Travelbyus (save and except that (i) the covenants and agreements of
the Londons shall be on a joint and several basis with each other; (ii) the
covenants and agreements of the Hohensteins shall be on a joint and several
basis with each other; (iii) the covenants and agreements of the Hornsbys shall
be on a joint and several basis with each other; and (iv) the covenants and
agreements of the Kavanaughs shall be on a joint and several basis with each
other) and the Targets that they will not (without the prior written consent of
Travelbyus and/or the Targets) directly or indirectly, in any manner whatsoever,
including without limitation, either individually or in partnership or jointly
or in conjunction with any other person or persons, firm, association,
syndicate, company or corporation, as principal, agent, shareholder, consultant
or in any other manner whatsoever during the term of the applicable Employment
Agreement and for a period ending one year after the termination of the
applicable Employment Agreement (with respect to J. Michael London) and for a
period ending two years with respect to each of the other Sellers, carry on or
be engaged in any business within two years which is competitive with the
Business or any other business then carried on by the Targets (a "Competitive
Business") or be concerned with or interested in or lend money to, guarantee the
debts or obligations of or permit their name or any part thereof to be used by
any person, persons, firm, association, syndicate, company or corporation
<PAGE>

                                      -37-

engaged or concerned with or interested in a Competitive Business.

Notwithstanding the foregoing provisions, the Sellers may invest in stocks,
bonds or other securities in any Competitive Business (but without participating
in such Competitive Business) if:

     (a)  the stocks, bonds or other securities of the Competitive Business are
          listed on any national or regional securities exchange or are publicly
          traded over the counter;

     (b)  their investment in the Competitive Business does not exceed, in the
          case of any class of capital stock, five percent of the issued and
          outstanding shares or in the case of bonds or other securities, five
          percent of the aggregate principal amount thereof issued and
          outstanding; and

     (c)  such investment would not prevent, directly or indirectly, the
          transaction of business by the Targets with any federal, state or
          provincial government of Canada or the United States of America or any
          governmental subdivision, agency or instrumentality thereof by virtue
          of any statute, law, regulation or administrative practice.

11.3 Injunctive Relief.  The Sellers acknowledge and agree that the agreements
     -----------------
and covenants in this Article 11 are essential to the transactions contemplated
in this Agreement and further to protect the business and goodwill of the
Targets and that a breach by the Sellers of the covenants in this Article 11
could result in irreparable loss to the Targets which could not be adequately
compensated for in damages and that Travelbyus may have no adequate remedy at
law if the Sellers breach such provisions.  Consequently, if the Sellers breach
any of such provisions, in addition to and not in lieu of, any other rights and
remedies available to Travelbyus under any law or in equity, Travelbyus shall
have the right to obtain injunctive relief to restrain any breach or threatened
breach thereof and to have such provisions specifically enforced by any court of
competent jurisdiction.
