         Bolton, Paul Abraham and James R. Stevens, have entered into an asset
         purchase agreement (the "Agreement"), the result of which will be the
         acquisition by EXFO Gnubi of substantially all the assets of Gnubi
         Communications for a total consideration of between US$4,280,205 and
         US$7,230,205 payable by way of US$2,500,000 through the issuance of
         subordinate voting shares of EXFO at closing, US$1,780,205 in cash at
         closing, and a further amount payable in cash one (1) year and sixty
         (60) days after the closing that will be established in relation to a
         percentage of earnings of EXFO Gnubi but which shall not exceed
         US$2,950,000.




ITEM 5:  FULL DESCRIPTION OF MATERIAL CHANGE

         The Agreement provides for the purchase by the subsidiary of EXFO, EXFO
         Gnubi, incorporated pursuant to the laws of the State of Delaware, of
         substantially all the assets of Gnubi Communications. At closing, the
         Gnubi Shareholders shall have the right to receive cash and EXFO
         subordinate shares, as well as a further amount of cash one (1) year
         and sixty (60) days after the closing.

         The total consideration (the "Asset Consideration") to be paid by EXFO
         and EXFO Gnubi in the asset acquisition shall be between US$4,280,205
         and US$7,230,205 consisting of (a) US$1,780,205 payable in cash at
         closing; (b) US$2,500,000 payable in the form of subordinate voting
         shares of EXFO (the "Stock Consideration") at closing; and (c) an
         amount payable in cash one (1) year and sixty (60) days after the
         closing that will be established in relation to a percentage of
         earnings of EXFO Gnubi but which shall not exceed US$2,950,000.

         The Agreement provides for the following:

         (a)      The aggregate number of shares of EXFO payable shall be
                  determined by dividing the amount of the Stock Consideration
                  by the Closing Price. The Closing Price shall be the average
                  closing price per share of the subordinate voting shares of
                  EXFO for the ten (10) trading days ending on the third day
                  immediately preceding the closing, as reported by the Nasdaq
                  National Market.

         (b)      The Gnubi Shareholders representing in the aggregate 100% of
                  the Stock Consideration to be issued as a result of the asset
                  acquisition have agreed to a lock-up of their shares. Such
                  shareholders have agreed to lock-up 100% of the EXFO
                  subordinate voting shares received by such shareholders from
                  the transaction. The shares subject to the lock-up shall be
                  released as to 1/3 on each anniversary date of the closing
                  starting on the first anniversary of the closing.

         The transaction is expected to close in October 2002. The Agreement
         contains provisions that are customary in agreements of this nature and
         is subject to regulatory approval.
