(hereinafter collectively referred to as the "Selling Shareholder"), desires to
sell to a third party with whom the Selling Shareholder is dealing at Arm's
Length all but not less than all of the Shares of the Selling Shareholder, the
Selling Shareholder shall obtain from the third party a bona fide offer in
writing which offer shall be irrevocable for a period of 60 days (hereinafter in
this Section 7.2 and Sections 7.3, 7.4 and 7.5 referred to as the "Offer") which
it is ready and willing to accept, to purchase all of the Shares for the amount
thereof set forth in the Offer by cash or certified cheque and shall give notice

<PAGE>   21
                                       17

                  holdings of Shares a fraction of the number of Shares which
                  are the subject matter of the Offer, which fractions shall
                  have as their numerators, in the case of Selling Shareholder,
                  the number of Shares held by the Selling Shareholder, and in
                  the case of the Electing Shareholder, the number of Shares
                  held by the Electing Shareholder, and the denominator of both
                  such fractions shall be the sum of the number of Shares held
                  by the Selling Shareholder and the Electing Shareholder, for
                  the same price per Share, and at the same time and on the same
                  terms and conditions as contained in the Offer, in which case
                  the Electing Shareholder shall become a "SELLING SHAREHOLDER"
                  for purposes of this Article 7; or

         (b)      if the Selling Shareholder is any of Rivard, Cargnelli or
                  Taylor, as a condition precedent to any sale of the Shares by
                  the Selling Shareholder, require the third party to amend the
                  Offer to provide for the purchase of all of the Shares (or
                  such lesser number as is the subject matter of the Offer) held
                  by the Electing Shareholder, for the same price per Share, and
                  at the same time and on the same terms and conditions as
                  contained in the Offer, in which case the Electing Shareholder
                  shall become a "Selling Shareholder" for purposes of this
                  Article 7.

7.4      RIGHT OF FIRST REFUSAL.

Except in the case where Section 7.6 shall apply, the other Shareholders shall
have the irrevocable right, exercisable by written notice given to the Selling
Shareholder within 30 days after the giving of the notice by the Selling
Shareholder, to purchase all but not less than all of the Shares of the Selling
Shareholder or, if CIBC, MG Fund, WV or DVI has exercised its option set forth
in Section 7.3, the number of Shares of the initial Selling Shareholder and of
CIBC, MG Fund, WV and DVI which are the subject matter of the Offer (in either
case, the "Selling Shareholders Shares"), and, if provided for in the Offer,
indebtedness owed by the Corporation to the Selling Shareholder on the terms and
conditions and for the amount set forth in the Offer by cash or certified cheque
pro rata in proportion to their respective holdings of Shares (or in such other
proportions as they may agree among themselves). In the event that one or more
of the Shareholders elects to purchase his or its pro rata proportion of the
Selling Shareholders Shares and, if applicable, indebtedness owed to the Selling
Shareholder and one or more of the Shareholders declines to elect to so
purchase, the Shareholder(s) electing to so purchase shall have the further
right and option, exercisable by notice in writing within 5 days of being
notified by the Selling Shareholder that one or more of the Shareholders has
declined to so purchase, to purchase the remaining Selling Shareholders Shares
and, if applicable, indebtedness owed to the Selling Shareholder on the same
terms and conditions and for the amount set forth in the Offer by cash or
certified cheque pro rata in proportion to their respective holdings of Shares
of such Shareholders (or in such other proportions as they may agree among
themselves). The foregoing procedure shall be repeated as often as is necessary
until either one or more of the Shareholders have elected to acquire all of the
Selling Shareholders Shares and, if applicable, the indebtedness owed to the
Selling Shareholder or until there remain Shares which no Shareholder has
elected to purchase. Where one or more of the Shareholders have elected to
purchase all of the Selling Shareholders Shares, the Offer of the Shareholders
so electing for the Shares and, if applicable, the indebtedness owe to the
Selling Shareholder shall be completed in accordance with its terms.
<PAGE>   22
                                       18

If there shall remain Shares which no Shareholder has elected to purchase,
notwithstanding that one or more Shareholders has elected to purchase Selling
Shareholders Shares pursuant to this Section 7.4, the right of any Shareholders
to acquire the Selling Shareholders Shares and, if applicable, the indebtedness
owed to the Selling Shareholder shall be null and void and the provisions of
Section 7.5 shall apply.

7.5      SALE OF SHARES - RIGHT OF FIRST REFUSAL NOT EXERCISED.

If following compliance with Section 7.4 there shall remain Shares which no
Shareholder has elected to purchase, the Selling Shareholder shall accept the
Offer and complete the transaction with the said third party in accordance with
the terms and conditions of such third party's Offer and the parties hereby
agree to take all steps and proceedings required to have such third party
entered on the books of the Corporation as a shareholder and, if applicable, as
a debtholder of the Corporation, provided that if the sale of such Shares to the
third party is not completed, the provisions of Article 7 shall again apply to
any proposed sale of Shares. The Selling Shareholder is hereby irrevocably
appointed the agent and attorney of the Shareholders and each of them for the
purposes of effecting registration of the third party as a Shareholder of the
Corporation. The Board of Directors or the Shareholders (including the Selling
Shareholder), as the case may be, before consenting to the transfer of the
purchased Shares to the third party, shall require proof that the sale took
place in accordance with the third party's Offer and the Board of Directors
shall refuse the recording of the transfer of the purchased Shares which may
have been sold otherwise than in accordance with the provisions of such Offer
and of this Agreement.

7.6      DRAG-ALONG RIGHTS.

If any of the Shareholders receive a Take-Over Bid, as hereinafter defined,
which such Shareholder(s) wish to accept, such recipient Shareholder(s) shall
forthwith provide a copy of the Take-Over Bid to the other Shareholders together
with a notice that he, she or it wishes to invoke the provisions of this Section
7.6 in which case if Shareholders holding not less than 77% of the total number
of issued and outstanding Shares, and including at least one of CIBC, MG Fund,
or WV, wish to accept such Take-Over Bid, such Shareholders shall have the right
to require the other Shareholders, on 10 days notice in writing to such other
Shareholders, to sell all of the Shares held by them to the third party pursuant
to the terms of the Take-Over Bid for the amount set forth in the Take-Over Bid.
The Corporation is hereby irrevocably appointed the agent and attorney of all
the Shareholders and each of them for the purposes of effecting registration of
the third party as a Shareholder and, if applicable, debtholder of the
Corporation in completing the sale of the Shares of such other Shareholders to
the third party in accordance with this Section 7.6. For purposes hereof,
"Take-Over Bid" shall mean an offer for all of the Shares made by a third party
dealing at Arm's Length with all of the Shareholders and the Corporation which
complies with the following:

         (a)      the Take-Over Bid must provide for a purchase of the Preferred
                  Shares at a price in cash and which is the greater of the
                  Minimum Purchase Price as defined in the Articles and the
                  price which should be payable if all of the Preferred Shares
                  were converted to Common Shares in accordance with the
                  Articles;
<PAGE>   23
                                       19

         (b)      the Take-Over Bid shall not provide for the provision of
                  management, consulting or other fees, the payment for any
                  non-competition covenant, or the payment of salary which any
                  two of CIBC, MG Fund, WV and DVI in their sole discretion
                  determine to be reasonably attributable to the purchase price
                  as opposed to fair consideration for future services to be
                  rendered by the Shareholders or any of their Affiliates,
                  including the purchaser, or any other Person with whom the
                  Shareholder does not deal at Arm's Length. In addition, no
                  other consideration may be paid by the offeror or its
                  Affiliates otherwise than as set forth in the offer;

         (c)      the liability of each Shareholder under the purchase agreement
                  including, without limitation, liability for a breach of
                  representation or warranty or for a claim under an indemnity
                  shall be several and not joint and several and shall not,
                  under any circumstances, exceed the lesser of their pro rata
                  proportion of any claim and the purchase price payable to each
                  Shareholder as the case may be; and

         (d)      the Take-Over Bid shall contain no provision which would
                  prevent or restrict CIBC's, MG Fund's or WV's ability to make
                  investments in any business.

7.7      PUT OPTION.

Each of CIBC, MG Fund, WV and DVI shall have the right (the "Put Option") at any
time after five years from the date hereof to require the Corporation to
purchase from CIBC, MG Fund, WV or DVI, as the case may be, all, but not less
than all, of CIBC's, MG Fund's, WV's or DVI's Shares (hereinafter in Sections
7.7, 7.8 and 7.9 referred to as the "Putting Shareholder"). Any purchase of the
Putting Shareholder's Shares in accordance with this Section by the Corporation,
or, if the Shareholders elect in accordance with subsection 7.7(c), by the
Shareholders (such Shareholders or the Corporation, as the case may be, being
hereinafter referred to in this Section as the "Purchaser(s)"), shall be subject
to the following terms and conditions, notwithstanding the provisions of Section
7.2.

         (a)      the Put Option shall be exercised by the Putting Shareholder
                  giving to the Corporation and each of the other Shareholders
                  notice in writing (in this Article called the "Put Notice") of
                  the Putting Shareholder's intention to exercise the Put
                  Option;

         (b)      the Put Notice shall also set forth the Putting Shareholder's
                  best estimate, stated in dollars, of the Fair Market Value of
                  its Shares, which, subject to Section 7.8, shall be the
                  purchase price payable by the Purchaser(s);

         (c)      the Shareholders other than the Putting Shareholder shall have
                  the option, exercisable in writing to purchase the Putting
                  Shareholder's Shares, in place of or in addition to the
                  Corporation, in such proportions as may be specified in a
                  notice given by the Shareholders other than the Putting
                  Shareholder to the Putting Shareholder and to the Corporation
                  within 30 days of receipt of the Put Notice. If the
                  Shareholders other than the Putting Shareholder so elect, such
                  of them who
<PAGE>   24
                                       20

                  have elected to be Purchasers, shall be obligated to purchase
                  the Putting Shareholder's Shares, but the Corporation shall
                  not thereby be relieved of its obligation to purchase Putting
                  Shareholder's Shares if the Shareholders who are the
                  Purchasers fail to complete the transaction in accordance with
                  this Section;

         (d)      the purchase price shall be payable in full in cash or by
                  certified cheque or bank draft at the time of completion of
                  the transaction;

         (e)      upon the completion of the transaction, the Putting
                  Shareholder shall cause its nominee(s) to resign from all
                  offices and positions with the Corporation and release the
                  Corporation from any claims other than for contribution and
                  indemnity;

         (f)      the completion of the transaction shall take place at the
                  offices of the Putting Shareholder, before or on the date
                  being 120 days after the date on which the Putting Shareholder
                  delivered the Put Notice, or if a Dispute Notice is duly given
                  under Section 7.8, before or on the date being 45 days after
                  determination of the purchase price in accordance with Section
                  7.8;

         (g)      the Purchaser(s) shall use its best efforts to cause the
                  Putting Shareholder to be fully released from all obligations
                  under any guarantees or indemnities which may have been given
                  by the Putting Shareholder for or in respect of any debts,
                  liabilities or obligations of the Corporation, provided that
                  if the Purchaser(s) are unable to obtain any such release then
                  the Purchaser(s) shall indemnify the Putting Shareholder
                  against any loss it may suffer or incur as a result of having
                  given any said guarantee or indemnity; and

         (h)      in the event that the Putting Shareholder exercises the Put
                  Option and all of the Putting Shareholder's Shares are not
                  acquired by either the Corporation or the Shareholders in
                  accordance with this Section 7.7, without prejudice to any
                  other rights which the Putting Shareholder may have, the
                  provisions of Section 7.9 shall apply.

All of the Shareholders hereby agree that in the event that any of CIBC, MG
Fund, WV or DVI exercise the Put Option under this Section 7.7, the rights of
all Shareholders under the redemption provisions contained in section 6 of the
Series A and Series B Preferred Share provisions of the Company included in
Schedule A to the Articles of the Company as amended January 21, 2000 shall be
suspended until such time as all of the Company's obligations in connection with
the Put Option so exercised shall have been discharged.

7.8      PRICE RESOLUTION.

In the event that any of the Purchaser(s) disagree with the Fair Market Value
contained in the Put Notice given by the Putting Shareholder under Section 7.7,
such Purchaser(s) shall have 15 days from the date the Put Notice is received
within which to give written notice of such disagreement (in this Article called
the "Dispute Notice") to the Putting Shareholder and any other

                  been received by such lending Related Party but for the
                  provisions of Section 10.1, until the principal of and
                  interest on the Other Indebtedness shall be paid in full. No

                  lending Related Party which would be payable or distributable
                  to the holder of Other Indebtedness pursuant to this Section
                  10.1 shall (to the extent paid over to or held for the account
                  of holders of Other Indebtedness), as between the Corporation,
                  its creditors (other than the holders of Other Indebtedness)
                  and such lending Related Party, be deemed to be a payment by
                  the Corporation to or on account of such lending Related
                  Party, it being understood that the provisions of this Section
                  10.1 are, and are intended, solely for the purpose of defining
                  the relative rights of the lending Related Party, on the one
                  hand, and the holders of the Other Indebtedness on the other
                  hand. Nothing contained in this Section 10.1 is intended to or
                  shall impair, as between the Corporation and its creditors
                  (other than the holders of Other Indebtedness and the lending
                  Related Party), the obligation of the Corporation, which is
                  unconditional and absolute, to pay to the lending Related
                  Party the principal of and interest on his, her or its Related
                  Party loan and any other amounts payable under his, her or its
                  Related Party loan as and when the same shall become due and
                  payable in accordance with the terms hereof, or to affect the
                  relative rights of the lending Related Party and creditors of
                  the Corporation, other than the holders of the Other
                  Indebtedness, nor shall anything herein or therein prevent the
                  lending Related Party from exercising all remedies otherwise
                  permitted by applicable law upon default under his, her or its
                  Related Party loan subject to the right(s), if any under this
                  Section 10.1, of the holders of Other Indebtedness upon the
                  exercise of any such remedy.

         (e)      In the event that, notwithstanding the foregoing provisions of
                  this Section 10.1, the lending Related Party shall have
                  received any payment after a Proceeding has commenced before
                  all Other Indebtedness has been paid in full, the lending
                  Related Party shall hold such payment in trust for the benefit
                  of the holders of Other Indebtedness and shall forthwith upon
                  the completion of the Proceeding pay such payment over to such
                  holders of Other Indebtedness for application against unpaid
                  Other Indebtedness.

                                       27

         (f)      For greater certainty, this Section 10.1 shall not be
                  construed so as to prevent the lending Related Party from
                  receiving and retaining any payments on account of his, her or
                  its Related Party loan which are made (A) in a manner that is
                  consistent with the terms of his, her or its Related Party
                  loan and (B) at any time when no event of default, as defined
                  in any Other Indebtedness or the instrument creating the same,
                  has occurred and is continuing and in respect of which notice
                  has been given by or on behalf of the holders of Other
                  Indebtedness to the Corporation and the Related Party. Until
                  written notice shall be given to the Related Party by or on
                  behalf of any holder of any Other Indebtedness of the
                  occurrence of any default with respect to such Other
                  Indebtedness or the existence of any other facts which would
                  have the result that any payment with respect of any Related
                  Party loan would be in contravention of the provisions of this
                  Section 10.1, the lending Related Party shall be entitled to
                  assume that no such default has occurred, or that no such
                  facts exist.

         (g)      The holders of Other Indebtedness shall be entitled to rely
                  and shall be third party beneficiaries of the provisions of
                  this Section 10.1.

         (h)      The provisions of this Section 10.1 shall have no application
                  to loans made by WV to the Corporation.

10.2     FUTURE DEBT FINANCINGS.

If the Corporation requires additional capital by way of debt, it shall first
advise CIBC, MG Fund, WV and DVI of its requirements in writing. Upon receiving
such notice, CIBC, MG Fund, WV and DVI shall have 30 days within which to notify
the Corporation if they wish to provide the required financing on such terms and
conditions as may be negotiated between such parties. During that time, the
Corporation shall provide to CIBC, MG Fund, WV and DVI, at their request, all
such information as CIBC, MG Fund, WV and DVI may reasonably require to make its
determination. In the event that the parties are unable to agree upon the terms
of the financing within such 45 day period, the Corporation shall deliver,
within 5 days following the expiry of such 45 day period, a term sheet outlining
the terms and conditions upon which it would be prepared to proceed with the
financing. CIBC, MG Fund, WV and DVI shall have a further period of 10 days
within which to accept or reject the terms of financing. In the event that CIBC,
MG Fund, WV and DVI all reject the terms of financing or fail to give notice
within the prescribed time period as aforesaid, the Corporation shall be free to
pursue obtaining its debt financing with other Persons on terms no less
favourable to the Corporation or more favourable to such Persons than those set
forth in the term sheet provided to CIBC, MG Fund, WV and DVI. In the event that
any of CIBC, MG Fund, WV or DVI rejects the terms of financing or fails to give
notice within the prescribed time period, the remaining of CIBC, MG Fund, WV or
DVI, as the case may be, may alone or in connection with other Persons provide
the required financing to the Corporation.

10.3     FUTURE EQUITY FINANCINGS.

If the Corporation requires additional capital by way of equity, the Corporation
shall provide written notice to the Shareholders specifying the terms and
conditions of the proposed equity issue including the amount of financing to be
raised, the type of security to be issued, the price per security to be issued
and the target completion date. Each Shareholder shall have the irrevocable
right, exercisable by written notice given to the Corporation within 30 days
after the giving of above notice by the Corporation, to participate in the
equity financing on a pro rata basis based on the number of Shares held by such
Shareholder on the terms and conditions set forth by the Corporation. In the
event that one or more Shareholders elects to subscribe for his or its pro rata
proportion of the proposed equity issue and one or more Shareholders declines to
so subscribe, the Shareholder(s) electing to so subscribe shall have the further
right and option, exercisable by notice in writing within 5 days of being
notified by the Corporation that one or more Shareholders has declined to so
subscribe, to subscribe for the remaining equity on the same terms and
conditions as set forth by the Corporation in proportion to their respective
holdings of Shares (or in such other proportions as they may agree among
themselves). The foregoing procedure shall be repeated as often as is necessary
until the equity issue is fully subscribed or until there remains equity which
no Shareholder has elected to subscribe for. If there remains equity which no
Shareholder has elected to subscribe for, the Corporation may elect to proceed
with the equity financing in an amount equal to the amount subscribed for under
this Section 10.3 or decline to proceed and to pursue its equity capital
requirements through other sources on terms and conditions no more favourable
than the terms and conditions specified to the Shareholders. Nothing contained
in this Section 10.3 shall affect the condition that any proposed equity
financing is subject to the written approval of not less than three of CIBC, MG
Fund, WV and DVI in accordance with Section 5.10 of this Agreement.

10.4     EXCEPTIONS TO PRE-EMPTIVE RIGHTS.

Notwithstanding Section 10.3 hereof, no Shareholder shall have any rights
thereunder in respect of:

         (a)      the issue of any options or shares of the Corporation pursuant
                  to a stock option plan for employees and other persons
                  approved by the Board of Directors and consented to in
                  accordance with Section 5.10 hereof; or

         (b)      shares issued as a stock dividend or pursuant to the exercise
                  of conversion privileges, options or rights previously granted
                  by the Corporation in accordance with Section 10.3.

11.3     ENDORSEMENT OF SHARE CERTIFICATES.

Any and all certificates representing Shares now or hereafter beneficially owned
by the Shareholders during the term of this Agreement shall have endorsed
thereon, in bold type, the following legend:

               24, 2000 made  between the  Corporation  and each and

Neither this Agreement nor any rights or obligations hereunder are assignable by
the parties hereto without the prior written consent of the other parties
hereto, subject to the rights of Shareholders to sell their Shares pursuant to
the terms of this Agreement and provided that the purchaser of such Shares
agrees to be bound hereby. This Agreement shall enure to the benefit of and be
binding upon the parties hereto and their respective heirs, executors, legal
personal representatives, successors and permitted assigns.

11.5     COUNTERPARTS.

         (a)      This Agreement may be executed by the parties hereto in
                  separate counterparts each of which when so executed and
                  delivered shall be an original, but all such counterparts
                  shall together constitute one and the same instrument.

         (b)      This Agreement may also be executed by any of the parties
                  hereto by such party executing and delivering to the
                  Corporation a counterpart in the form set out as Schedule "E"
                  to this Agreement, whereupon such party shall become bound by,
                  and entitled to the benefits of this Agreement as fully and
                  effectively as though such party had executed this Agreement
                  together with the other parties to this Agreement.

         (c)      Any Person who acquires Shares on or subsequent to the date
                  hereof in accordance with the terms of this Agreement and who
                  executes a counterpart to this Agreement in the form set forth
                  in Schedule "E" hereto shall be deemed to be a party to this
                  Agreement and be entitled to the rights and subject to the
                  obligations set forth herein, with like effect as if such
                  Person had been an original party hereto, except that the
                  rights and obligations of such Person pursuant hereto shall
                  arise only as of and from the later of the date on which such
                  Person (i) acquired Shares in accordance with the terms of
                  this Agreement; and (ii) executed such counterpart.

11.6     PUBLICITY.

Each of the Legacy Investors hereby irrevocably makes, constitutes and appoints
the Corporation as his true and lawful attorney and agent, with full power and
authority in his name, place and stead and for his use and benefit to execute
all documents and do all such things, including the approval of any additions,
changes or amendments to this Agreement, as in the Corporation's opinion may be
necessary or desirable to give effect to the terms of this Agreement.

The parties hereto agree to treat all information, data, reports and other

and will not disclose such information to any other person other than their

provided, however,
<PAGE>   35
                                       31

that no Shareholder shall be liable for any such disclosure of such information
of such Shareholder if such information:

         (a)      becomes generally available to the public other than as a
                  result of a disclosure by the Shareholder or its
                  representatives in violation of this Agreement;

         (b)      was available to the Shareholder on a non-confidential basis
                  without violation of this Agreement prior to its disclosure by
                  the Corporation or its representatives;

         (c)      becomes available to the Shareholder on a non-confidential
                  basis without violation of this Agreement from a source other
                  than the Corporation or its representatives provided that such
                  source is not bound by a confidentiality agreement with the
                  Corporation or a duty of confidentiality to or in respect of
                  the Corporation to the knowledge of the Shareholder; or

         (d)      is required by law to be disclosed by the Shareholder,
                  provided that the Shareholder first notifies the Corporation
                  that it believes it is required to disclose such information
                  and it allows the Corporation a reasonable period of time to
                  contest the disclosure of such information.

12.2     SURVIVAL.

The terms of this Article 12 and of Article 8 shall survive any termination of
this Agreement without limit as to time.
