Part II - Rules 12b-25(b) and (c)

If the subject report could not be filed without unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25(b), the following should
be completed. (Check box if appropriate)

[  ]     (a)      The reasons  described in  reasonable  detail in Part III of
                  this form could not be eliminated  without  unreasonable
                  effort or expense;

[x]      (b)      The subject annual report, semi-annual report, transition
                  report on Form 10-K, Form 20-F, 11-K, Form N-SAR, or portion
                  thereof, will be filed on or before the fifteenth calendar day
                  following the prescribed due date; or the subject quarterly
                  report or transition report on Form 10-Q, or portion thereof
                  will be filed on or before the fifth calendar day following

PART III - NARRATIVE

State below in reasonable  detail the reasons why the Form 10-K and Form 10-KSB,
20-F,  11-K, 10-Q and Form 10Q-SB,  N-SAR,  or the transition  report or portion
thereof,  could not be filed within the  prescribed  time period.  (Attach Extra
Sheets if Needed)

         The registrant is unable to timely file its annual report on Form
         10-QSB for the quarter ended March 31, 2001 without unreasonable effort
         or expense due to the additional time needed by the registrant to
         consolidate the financial reporting of the constituent companies to the
         Arrangement described in response to the question in Part IV, Item 3,
         below, one of which constituents has historically reported its
         financial results in accordance with accounting principles generally
         accepted in Canada.

PART IV - OTHER INFORMATION

(1)      Name and telephone number of person to contact in regard to this
         notification.

         Richard Morgan               214                      922-8100
         --------------           -----------             ----------------
         (Name)                   (Area Code)            (Telephone Number)

(2)      Have all other periodic reports required under Section 13 or 15(d) of
         the Securities Exchange Act of 1934 or Section 30 of the Investment
         Company Act of 1940 during the preceding 12 months or for such shorter
         period that the registrant was required to file such report(s) been
         filed? If answer is no, identify report(s).

                                    [x] Yes [ ] No

(3)      Is it anticipated that any significant change in results of operations
         from the corresponding period for the last fiscal year will be
         reflected by the earnings statements to be included in the subject
         report or portion thereof?

                                    [x] Yes [ ] No

If so, attach an explanation of the anticipated change, both narratively and
quantitively, and, if appropriate, state the reasons why a reasonable estimate
of the results cannot be made.

          On January  25,  2001,  Aviation  Group,  Inc.,  a Texas  corporation,
          completed an  arrangement  (the  "Arrangement")  with  travelbyus.com,
          Ltd.,  an  Ontario  corporation,  in  which  the  operations  of these
          companies  were  combined.  Immediately  prior  to  completion  of the
          Arrangement, Aviation Group, Inc. changed its name to travelbyus, Inc.
          Under the terms of the Arrangement, Aviation Group, Inc. was the legal
          acquirer of  travelbyus.com,  Ltd.  and  travelbyus.com,  Ltd. was the
          accounting acquirer. Accordingly, the historical financial information
          to be set forth in the registrant's 10-QSB for the quarter ended March
          31,  2001 will be that of the  accounting  acquirer,  travelbyus.com.,
          Ltd.,  which   historically  has  been  reported  in  accordance  with
          accounting  principles generally accepted in Canada.  Principally as a
          result  of the  consolidation  of  the  constituent  companies  in the
          Arrangement,  the results of operations of the registrant reported for
          the  three  months  ended  March  31,  2001  are   anticipated  to  be
          significantly  different from (i) the historical  financial results of
          Aviation Group,  Inc.  reported in the quarterly report on Form 10-QSB
          for the quarter ended March 31, 2000, and (ii) the historical  results
          for the  accounting  acquirer,  travelbyus.com,  Ltd.  for the quarter
          ended March 31, 2000 that will be included in the forthcoming 10-QSB.

          The  registrant has not completed its  consolidation  of the financial
          results of the  constituent  companies to the  Arrangement or made the
          necessary   adjustments   associated  with  such   consolidation  and,
          therefore,  is unable to provide a meaningful  estimate of its results
          for the three and six months ended March 31, 2001.
