                           the availability of equitable remedies;

                  4.1.6    that the execution, delivery and performance of this
                           Agreement does not and will not contravene the
                           provisions of its articles, by-laws, constating

                           substance satisfactory to legal counsel to the
                           Company, which contains a representation and warranty
                           by the Controlled Entity and the Shareholder that (i)
                           the Controlled Entity is Controlled by the

                  4.3.3    the Controlled Entity shall have executed an
                           intervention in the form of Schedule 4.11;

                  4.3.4    the Shareholder Transferring its Shares to a
                           Controlled Entity shall have executed and delivered

                           legal counsel to the Company, in which the
                           Shareholder acknowledges and agrees to be bound,
                           solidarily with the Controlled Entity, by all the

                           Controlled Entity, and not to permit the issuance of


                                       13


                           any shares in the capital stock of the Controlled
                           Entity nor permit the Transfer of any such shares to
                           a third party, without the consent of the other
                           Shareholders, failing which the initial Transfer by
                           the Shareholder of its Shares to a Controlled Entity
                           shall be deemed to be and shall be in violation of

         4.4      Transfer to Affiliates

                  Notwithstanding any provision of this Agreement other than
                  Section 4.10, each Shareholder may, at any time and from time
                  to time, Transfer all or any of the Shares held by it to any
                  of its Affiliates. A Shareholder must first notify the Company
                  in writing of such Transfer including the proposed transferee
                  and the Company reserves the right to prohibit any such
                  Transfer to an Affiliate who is a Competitor of the Company
                  and provided that such transferee shall have executed and
                  delivered an instrument, in form and substance satisfactory to
                  legal counsel to the Company, in which such transferee makes
                  the representations and warranties made by the Shareholders in
                  this Agreement and agrees to execute an intervention in the
                  form of Schedule 4.11, it being understood and agreed that (i)
                  such transferee, if same had acquired all of the Shareholder's
                  Shares, shall benefit from all the rights of such Shareholder
                  hereunder, as if such transferee had executed this Agreement
                  in lieu and place of such Shareholder and (ii) that such
                  Shareholder shall cease to be bound by the provisions hereof
                  (except for Section 5.2 which shall continue to apply). In the
                  event that only part of the Shares held by such Shareholder
                  holding Shares are transferred to such transferee, such
                  Shareholder holding Shares shall continue to be bound by the
                  provisions hereof in respect of the remaining Shares it holds.

                  to time, Transfer all or any of the Shares held by it to any
                  of its limited partners (a "Limited Partner") if such Transfer
                  results from a distribution by the Limited Partnership or the
                  wind-up of the Limited Partnership, in accordance with the
                  provisions of the limited partnership agreement governing it
                  provided that:

                  4.5.1    the Limited Partner shall have executed and delivered

                           legal counsel to the Company, in which the Limited
                           Partner makes the representations and warranties made
                           by the Shareholders under this Agreement and agrees
                           to execute an intervention in the form of Schedule
                           4.11;

                           Partner grants to the general partner of the


                                       14

                           irrevocable and unconditional grant, the right to
                           vote the Shares transferred to the Limited Partner at
                           all meetings of Shareholders and the right to execute
                           all documents and to do all things which a
                           Shareholder is permitted or required to do under this
                           Agreement; and

                  4.5.3    in the event that only part of the Shares held by the
                           Limited Partnership are Transferred to one or more of
                           its Limited Partners, such Limited Partnership shall
                           continue to be bound by the terms hereof in respect
                           of the remaining Shares it holds.

         4.6      Transfer by Celtic

                  Notwithstanding any provision of this Agreement other than

                  by amalgamation); or (b) a partner or partners of any limited
                  partnership referred to in (a) above, if such Transfer results
                  from a distribution by the limited partnership or the wind-up

                  of the limited partnership agreement governing it, or pursuant
                  to an agreement which requires such partner or partners to
                  Transfer such Shares to the limited partnership, provided in
                  each such case that such transferee is not a Competitor of the
                  Company and shall have executed and delivered an instrument,
                  in form and substance satisfactory to legal counsel to the
                  Company, in which such transferee makes the representations
                  and warranties made by the Shareholders under this Agreement
                  and any others required in the opinion of the Company to
                  comply with Section 4.10 and agrees to execute an intervention
                  in the form of Schedule 4.11, it being understood and agreed
                  that (i) such transferee, if same has acquired all of the
                  transferor's Shares, shall benefit from all the rights of such
                  transferor hereunder, as if such transferee had executed this
                  Agreement in lieu and place of such transferor and (ii) that
                  such transferor shall cease to be bound by the provisions
                  hereof (except for Section 5.2 which shall continue to apply).
                  In the event that only part of the Shares held by such
                  transferor are Transferred to such transferee, such transferor
                  shall continue to be bound by the provisions hereof in respect

         4.7      Right of First Refusal of Avensys

                  4.7.1    Except as otherwise provided herein, Avensys (the
                           "Offeror") shall be permitted to Transfer Shares only
                           if it receives a bona fide written offer (a "Third
                           Party Offer") from a Person (the "Third Party
                           Offeror") dealing at arm's length (as defined in the
                           Income Tax Act) to purchase all and not less than all


                                       15


                           of the Shares that it owns (the "Offered Shares").
                           The Third Party Offer must be a cash offer to
                           purchase only Shares and no other assets and provide
                           for the purchase of the Shares of the ITF Group for a
                           price equal to the greater of (a) the value of the
                           Shares of the ITF Group calculated on the basis of
                           the price per Offered Share set out in the Third
                           Party Offer or (b) $2,000,000. The Offeror shall give
                           a notice ("Notice") to the Company and the ITF Group
                           which Notice must contain a copy of the Third Party
                           Offer, disclose the identity of the Person making the
                           Third Party Offer and provide evidence sufficient to
                           establish that such Person has the power and
                           capacity, including financial capacity, to complete
                           the purchase of the Offered Shares and that the
                           conditions set out in Section 4.10 will be satisfied.
                           Upon the Notice being given, the ITF Group will have
                           the right, to be exercised within 30 days of receipt
                           of the Third Party Offer, to purchase all, but not
                           less than all, of the Offered Shares at the same
                           price and upon the same terms and conditions as are
                           contained in the Third Party Offer.

                  4.7.2    If the ITF Group is willing to purchase all, but not
                           less than all, of the Offered Shares as provided in
                           Section 4.7.1, the transaction of purchase and sale
                           will be completed in accordance with the terms set
                           out in the Third Party Offer by delivery of the
                           Offered Shares by the Offeror with good title, free
                           and clear of all liens, charges, encumbrances and any
                           other rights of others, against payment by certified
                           cheque or bank draft by the ITF Group. If, at the
                           time of completion, any Offered Shares are subject to
                           any lien, charge, encumbrance or other right of
                           others, the Offerees will be entitled to deduct from
                           the purchase money to be paid to the Offeror the
                           amount required to discharge all such liens, charges,
                           encumbrances or other rights of others and will apply
                           such amount to the repayment, on behalf of the
                           Offeror, of the obligations secured thereby.

                  4.7.3    If the ITF Group does not give notice that it wishes
                           to purchase the Offered Shares within 30 days of the
                           giving of the Notice, the rights of the ITF Group,
                           except as hereinafter provided, to purchase the
                           Offered Shares will terminate and Avensys and the ITF
                           Group must use their best efforts to sell to the
                           Third Party Offeror all, but not less than all, of
                           the Shares within 30 days after the expiry of the
                           30-day period. Any such sale must be at a price not
                           less than the purchase price contained in the Third
                           Party Offer and on other terms no more favourable to
                           Avensys than those contained in the Third Party
                           Offer.

                  4.7.4    If the Offeror defaults in transferring the Offered
                           Shares to the ITF Group as provided in this Section
                           4.7, the Company is authorized and directed to
                           receive the purchase money and thereupon to record
                           the transfer of the Offered Shares, to enter the
                           names of the ITF Group in the registers of the
                           Company as the holders of the Shares purchased by


                                       16


                           them, and to cause to be issued to the ITF Group
                           share certificates for the Offered Shares in the
                           names of the respective Preferred Holders. The
                           Company will hold the purchase money received by it
                           in trust on behalf of the Offeror and will not
                           commingle the purchase money with the Company's
                           assets, except that any interest thereon will be for
                           the account of the Company. The receipt by the
                           Company of the purchase money will be a good
                           discharge to the respective Preferred Holders and,
                           after their names have been entered in the registers
                           of the Company, the transaction of purchase and sale
                           will be deemed completed at the price and on the
                           other terms and conditions contemplated herein and
                           the respective Preferred Holders will for all
                           purposes own the Offered Shares purchased by them.
                           Upon such registration, the Offeror will cease to
                           have any right to or in respect of the Offered Shares
                           except the right to receive, without interest, the
                           purchase price received by the Company upon surrender
                           of any certificates that previously represented the
                           Offered Shares.

         4.8      Right of First Refusal of the Preferred Holders

                  4.8.1    Except as otherwise provided herein, each Preferred
                           Holder (each an "Offeror") shall be permitted on and
                           after May 1, 2009 to Transfer Shares only if it
                           receives a bona fide written offer (a "Third Party
                           Offer") from a Person (the "Third Party Offeror")
                           dealing at arm's length (as defined in the Income Tax
                           Act) to purchase all and not less than all of the
                           Shares that it owns (the "Offered Shares"). The Third
                           Party Offer must be a cash offer to purchase only
                           Shares and no other assets. The Offeror shall give a
                           notice ("Notice") to the Company and the other
                           Shareholders (the "Offerees") which Notice must
                           contain a copy of the Third Party Offer, disclose the
                           identity of the Person making the Third Party Offer
                           and provide evidence sufficient to establish that
                           such Person has the power and capacity, including
                           financial, to complete the purchase of the Offered
                           Shares and that the conditions set out in Section
                           4.10 will be satisfied. Upon the Notice being given,
                           the Offerees will have the right, to be exercised
                           within 30 days of receipt of the Third Party Offer,
                           to purchase all, but not less than all, of the
                           Offered Shares at the same price and upon the same
                           terms and conditions as are contained in the Third
                           Party Offer.

                  4.8.2    The Offerees will be entitled to purchase the Offered
                           Shares pro rata based upon the number of Shares owned
                           by the Offerees at the date the Notice was given or
                           in such other proportion as the Offerees may agree in
                           writing. Each Offeree who desires to purchase all the
                           Offered Shares that such Offeree is entitled to
                           purchase in accordance with the provisions of this
                           Section 4.8.2 will give notice of such desire to the
                           Offeror, to the Company and to the other Offerees
                           within 30 days of having been given the Notice.


                                       17


                  4.8.3    If any Offeree does not give notice as provided in
                           Section 4.8.2, the Offered Shares that such Offeree
                           had been entitled to purchase (the "Rejected Shares")
                           may instead be purchased by the Offerees who did give
                           such notice, pro rata based upon the number of Shares
                           owned by such Offerees at the date the Notice was
                           given or in such other proportion as such Offerees
                           may agree in writing, and, within five Business Days
                           of the expiry of the 30 day period specified in
                           Section 4.8.2, each Offeree who desires to purchase
                           all the Rejected Shares that such Offeree is entitled
                           to purchase in accordance with the provisions of this
                           Section 4.8.3 will give an additional notice to the
                           Offeror, to the Company and to the other Offerees. If
                           any Offeree entitled to give the additional notice
                           does not do so, the Rejected Shares that such Offeree
                           had been entitled to purchase may instead be
                           purchased by the Offerees who did give such
                           additional notice, pro rata based upon the number of
                           Shares owned by such Offerees at the date the Notice
                           was given or in such other proportion as such
                           Offerees may agree in writing, and so on from time to
                           time until the Offerees are willing to purchase all
                           the Offered Shares or until they are not willing to
                           purchase any more.

                  4.8.4    If the Offerees are willing to purchase all, but not
                           less than all, of the Offered Shares, the transaction
                           of purchase and sale will be completed in accordance
                           with the terms set out in the Third Party Offer by
                           delivery of the Offered Shares by the Offeror with
                           good title, free and clear of all liens, charges,
                           encumbrances and any other rights of others, against
                           payment by certified cheque or bank draft by the
                           Offerees. If, at the time of completion, any Offered
                           Shares are subject to any lien, charge, encumbrance
                           or other right of others, the Offerees will be
                           entitled to deduct from the purchase money to be paid
                           to the Offeror the amount required to discharge all
                           such liens, charges, encumbrances or other rights of
                           others and will apply such amount to the repayment,
                           on behalf of the Offeror, of the obligations secured
                           thereby.

                  4.8.5    If the Offeror defaults in transferring the Offered
                           Shares to the Offerees as provided in this Section
                           4.8, the Company is authorized and directed to
                           receive the purchase money and thereupon to record
                           the transfer of the Offered Shares, to enter the
                           names of the Offerees in the registers of the Company
                           as the holders of the Shares purchased by them, and
                           to cause to be issued to the Offerees share
                           certificates for the Offered Shares in the names of
                           such Offerees. The Company will hold the purchase
                           money received by it in trust on behalf of the
                           Offeror and will not commingle the purchase money
                           with the Company's assets, except that any interest


                                       18


                           thereon will be for the account of the Company. The
                           receipt by the Company of the purchase money will be
                           a good discharge to the Offerees and, after their
                           names have been entered in the registers of the
                           Company, the transaction of purchase and sale will be
                           deemed completed at the price and on the other terms
                           and conditions contemplated herein and the Offerees
                           will for all purposes own the Offered Shares
                           purchased by them. Upon such registration, the
                           Offeror will cease to have any right to or in respect
                           of the Offered Shares except the right to receive,
                           without interest, the purchase price received by the
                           Company upon surrender of any certificates that
                           previously represented the Offered Shares.

                  4.8.6    If the Offerees do not give notice in accordance with
                           the provisions of Section 4.8.2 that they are willing
                           to purchase all and not less than all the Offered
                           Shares, the rights of the Offerees, except as
                           hereinafter provided, to purchase the Offered Shares
                           will terminate and the Offeror may sell all, but not
                           less than all, of the Offered Shares to any person
                           within four months after the expiry of the 30 day
                           period specified in Section 4.8.2 or the last of the
                           five Business Day periods specified in Section 4.8.3,
                           as the case may be. Any such sale must be at a price
                           not less than the purchase price contained in the
                           Third Party Offer and on other terms no more
                           favourable to such person than those contained in the
                           Third Party Offer. If the Offered Shares are not sold
                           within such four month period on such terms, the
                           rights of the Offerees pursuant to this Section 4.7
                           will again take effect.

         4.9      No Registration of Transfer Unless Transferee is Bound

                  If, pursuant to any provision of this Agreement, a Shareholder
                  Transfers any of such Shareholder's Shares, no Transfer of
                  such Shares shall be made nor shall be effective, and no
                  application shall be made to the Company or to the Company's
                  transfer agent to register the Transfer, and the Company shall
                  not register any such Transfer on the securities register of
                  the Company, until:

                  4.9.1    in the case of a Transfer contemplated by Sections
                           4.3, 4.4, 4.5, 4.6, 4.7 or 4.8 the documentation
                           referred to in those Sections has been delivered; and

                  4.9.2    in the case of any other Transfer, the proposed
                           transferee and the Person, if any, who Controls such
                           transferee, become subject to all of the obligations
                           of the transferor under this Agreement, pursuant to
                           an agreement in writing, in form and substance
                           satisfactory to the legal counsel of the Company. If
                           such transferee has acquired all of the Shares of the
                           transferor (in which case the proposed transferee
                           shall become entitled to exercise all the rights of
                           the transferor under this Agreement) he or it agrees
                           to be bound by all of the provisions hereof as if he
                           or it were an original signatory hereto in the place
                           of the transferor, pursuant to an agreement in
                           writing, in form and substance satisfactory to the
                           legal counsel of the Company whereupon the transferor
                           shall cease to have any rights or obligations
                           hereunder.

                           the date hereof if in the opinion of the Company, the

                           tax credits would be imperilled; and

                  4.10.2   During the first three (3) years of this Agreement,
                           no Transfer of Shares may be made if:

                                    proposed sale by reason of the nationality
                                    or residence of the proposed purchaser or

                                    purchaser or transferee;

                           4.10.2.3 as a result, the remaining Shareholders or
                                    the Company would become subject to any

                                    they were not subject prior to the proposed
                                    sale;

                           4.10.2.4 the sale or transfer is not permitted by
                                    applicable law or any term of any material
                                    agreement affecting the Company, unless any
                                    required consent or approval is obtained; or

                           4.10.2.5 the proposed purchaser or transferee does
                                    not have the power and capacity, including

                                    calculated based on such Preferred Holder's

                                    Price, as defined in the Asset Purchase

                  4.13.2   In the event that any Preferred Holder exercises the
                           Put Option in accordance with Section 4.13.1, each of
                           the other Preferred Holders shall send a notice to

                                    owned by such Preferred Holder to Avensys in

                                    the Second Election Notice.

                           If a Preferred Holder does not send a Second Election
                           Notice within such 15 day time period, said Preferred
                           Holder will be deemed to have elected to exchange its
                           Shares in accordance with Section 4.13.2.1.

                  4.13.3   In the event that none of the Preferred Holders
                           exercises the Put Option in accordance with this
                           Section 4.13, the Shareholders agree to renegotiate
