                                   DIVIDENDS

3.1  Subject to Section 3.2 below, a holder of an Exchangeable Share shall be
entitled to receive and the Board of Directors shall, subject to applicable law,
on each SMTC Dividend Declaration Date, declare a dividend on each Exchangeable
Share:

     (a)  in the case of a cash dividend declared on the SMTC Common Stock, in
          an amount in cash for each Exchangeable Share in U.S. dollars, or, at
          the option of the Corporation, the Canadian Dollar Equivalent thereof
          on the SMTC Dividend Declaration Date, in each case, corresponding to
          the cash dividend declared on each share of SMTC Common Stock;

     (b)  in the case of a stock dividend declared on the SMTC Common Stock to
          be paid in SMTC Common Stock, in such number of Exchangeable Shares
          for each Exchangeable Share as is equal to the number of shares of
          SMTC Common Stock to be paid on each share of SMTC Common Stock; or

     (c)  in the case of a dividend declared on the SMTC Common Stock in
          property other than cash or SMTC Common Stock, in such type and amount
          of property for each Exchangeable Share as is the same as or
          economically equivalent to (as determined by the Board of Directors
          and as contemplated by Section 3.6 hereof) the type and amount of
          property declared as a dividend on each share of SMTC Common Stock.

3.2  In the case of a stock dividend declared on the SMTC Common Stock to be
paid in SMTC Common Stock, in lieu of declaring a corresponding stock dividend
on the Exchangeable Shares (as contemplated by Section 3.1(b) hereof), the Board
of Directors may, by resolution, in its discretion and subject to applicable
law, subdivide, redivide or change (each, a "Subdivision") each issued and
unissued Exchangeable Share on the basis that each Exchangeable Share before the
Subdivision becomes that number of Exchangeable Shares as is equal to the sum of
(i) one; and (ii) the number of shares of SMTC Common Stock to be paid as a
stock dividend on each share of SMTC Common Stock. In such instance, and
notwithstanding any other provision hereof, such Subdivision shall become
effective on the effective date specified in Section 3.4 hereof without any
further act or formality on the part of the Board of Directors or of the holders
of Exchangeable Shares. For greater certainty, no approval of the holders of
Exchangeable Shares to an amendment to the articles of the Corporation shall be
required to give effect to such Subdivision.

3.3  Cheques of the Corporation payable at par at any branch of the bankers of
the Corporation shall be issued in respect of any cash dividends contemplated by
Section 3.1(a) hereof and the sending of such a cheque to each holder of an
Exchangeable Share shall satisfy the cash dividend represented thereby unless
the cheque is not paid on presentation. Subject to applicable law, certificates
registered in the name of the registered holder of Exchangeable Shares shall be
issued or transferred in respect of any stock dividends contemplated by Section
3.1(b) hereof or any Subdivision contemplated by Section 3.2 hereof and the
sending of such a certificate to each holder of an Exchangeable Share shall
satisfy the stock dividend or

                                      -6-
<PAGE>

Subdivision represented thereby. Such other type and amount of property in
respect of any dividends contemplated by Section 3.1(c) hereof shall be issued,
distributed or transferred by the Corporation in such manner as it shall
determine and the issuance, distribution or transfer thereof by the Corporation
to each holder of an Exchangeable Share shall satisfy the dividend represented
thereby. No holder of an Exchangeable Share shall be entitled to recover by
action or other legal process against the Corporation any dividend that is
represented by a cheque that has not been duly presented to the Corporation's
bankers for payment or that otherwise remains unclaimed for a period of six
years from the date on which such dividend was payable.

3.4  The record date for the determination of the holders of Exchangeable Shares
entitled to receive payment of, and the payment date for, any dividend declared
on the Exchangeable Shares under Section 3.1 hereof shall be the same dates as
the record date and payment date, respectively, for the corresponding dividend
declared on the SMTC Common Stock. The record date for the determination of the
holders of Exchangeable Shares entitled to receive Exchangeable Shares in
connection with any Subdivision of Exchangeable Shares under Section 3.2 hereof
and the effective date of such Subdivision shall be the same dates as the record
date and payment date, respectively, for the corresponding stock dividend
declared on the SMTC Common Stock.

3.5  If, on any payment date for any dividends declared on the Exchangeable
Shares under Section 3.1 hereof, the dividends are not paid in full on all of
the Exchangeable Shares then outstanding, any such dividends that remain unpaid
shall be paid on a subsequent date or dates determined by the Board of Directors
on which the Corporation shall have sufficient moneys, assets or property
properly applicable to the payment of such dividends.

3.6  The Board of Directors shall determine, in good faith and in its sole
discretion, economic equivalence for the purposes of Sections 3.1 and 3.2
hereof, and each such determination shall be conclusive and binding on the
Corporation and its shareholders. In making each such determination, the
following factors shall, without excluding other factors determined by the Board
of Directors to be relevant, be considered by the Board of Directors:

     (a)  in the case of any stock dividend or other distribution payable in
          shares of SMTC Common Stock, the number of such shares issued in
          proportion to the number of shares of SMTC Common Stock previously
          outstanding;

     (b)  in the case of the issuance or distribution of any rights, options or
          warrants to subscribe for or purchase shares of SMTC Common Stock (or
          securities exchangeable for or convertible into or carrying rights to
          acquire shares of SMTC Common Stock), the relationship between the
          exercise price of each such right, option or warrant and the Current
          Market Price of a share of SMTC Common Stock;

     (c)  in the case of the issuance or distribution of any other form of
          property (including, without limitation, any shares or securities of
          SMTC of any class other than shares of SMTC Common Stock, any rights,
          options or warrants other than those referred to in Section 3.6(b)
          above, any evidences of indebtedness of SMTC or any assets of SMTC),
          the relationship between the fair market value

                                      -7-
<PAGE>

          (as determined by the Board of Directors) of such property to be
          issued or distributed with respect to each outstanding share of SMTC
          Common Stock and the Current Market Price of a share of SMTC Common
          Stock;

     (d)  in the case of any subdivision, redivision or change of the then-
          outstanding shares of SMTC Common Stock into a greater number of
          shares of SMTC Common Stock or the reduction, combination,
          consolidation or change of the then-outstanding shares of SMTC Common
          Stock into a lesser number of shares of SMTC Common Stock or any
          amalgamation, merger, reorganization or other transaction affecting
          shares of SMTC Common Stock, the effect thereof upon the then-
          outstanding shares of SMTC Common Stock; and

     (e)  in all such cases, the general taxation consequences of the relevant
          event to holders of Exchangeable Shares to the extent that such
          consequences may differ from the taxation consequences to holders of
          shares of SMTC Common Stock as a result of differences between
          taxation laws of Canada and the United States (except for any
          differing consequences arising as a result of differing marginal
          taxation rates and without regard to the individual circumstances of
          holders of Exchangeable Shares).

                                   ARTICLE 4

Agent, SMTC or the Corporation may reasonably require, at the registered office
of the Corporation or at any office of the Transfer Agent as may be specified by
the Corporation by notice to the holders of the Exchangeable Shares. Payment of
the total Company Liquidation Amount for such Exchangeable Shares shall be made
by delivery to each holder, at the address of the holder recorded in the
securities register of the Corporation for the Exchangeable Shares or by holding
for pick-up by the holder at the registered office of the Corporation or at any
office of the Transfer Agent as may be specified by the Corporation by notice to
the holders of Exchangeable Shares, on behalf of the Corporation, certificates
representing shares of SMTC Common Stock and a cheque of the Corporation payable
at par at any branch of the bankers of the Corporation in respect of the
remaining portion, if any, of the total Company Liquidation Amount (without
interest), in each case, less any amounts withheld pursuant to Section 12.3. On
and after the Company Liquidation Date, the holders of the Exchangeable Shares
shall cease to be holders of such Exchangeable Shares and shall not be entitled
to exercise any of the rights of holders in respect thereof, other than the
right to receive their proportionate part of the total Company Liquidation
Amount, unless payment of the total Company Liquidation Amount for such
Exchangeable Shares shall not be made upon presentation and surrender of share

                                      -9-
<PAGE>

certificates in accordance with the foregoing provisions, in which case the
rights of the holders shall remain unaffected until the total Company
Liquidation Amount has been paid in the manner hereinbefore provided. The
Corporation shall have the right at any time after the Company Liquidation Date
to deposit or cause to be deposited in a custodial account with any chartered
bank or trust company in Canada the total Company Liquidation Amount in respect
of the Exchangeable Shares represented by certificates that have not at the
Company Liquidation Date been surrendered by the holders thereof. Upon such
deposit being made, the rights of the holders of Exchangeable Shares after such
deposit shall be limited to receiving their proportionate part of the total
Company Liquidation Amount (without interest), in each case, less any amounts
withheld pursuant to Section 12.3 for such Exchangeable Shares so deposited,
against presentation and surrender of the said certificates held by them,
respectively, in accordance with the foregoing provisions. Upon such payment or
deposit of the total Company Liquidation Amount, the holders of the Exchangeable
Shares shall thereafter be considered and deemed for all purposes to be holders
of the SMTC Common Stock delivered to them or to the custodian on their behalf.

5.3  After the Corporation has satisfied its obligations to pay the holders of
the Exchangeable Shares the Company Liquidation Amount per Exchangeable Share
pursuant to Section 5.1 of these share provisions, such holders shall not be
entitled to share in any further distribution of the assets of the Corporation.

5.4  SMTC Nova Scotia shall have the overriding right (the "Liquidation Call
Right"), in the event of and notwithstanding the proposed liquidation,
dissolution or winding-up of SMTC Canada pursuant to these share provisions, to
purchase from all but not less than all of the holders of Exchangeable Shares
(other than any holder of Exchangeable Shares which is SMTC or an Affiliate of
SMTC) on the Company Liquidation Date all but not less than all of the
Exchangeable Shares held by each such holder on payment by SMTC Nova Scotia of
an amount per share (the "Liquidation Call Purchase Price") equal to the Current
Market Price of a share of SMTC Common Stock on the last Business Day prior to
the Company Liquidation Date, which shall be satisfied in full by SMTC Nova
Scotia causing to be delivered to such holder one share of SMTC Common Stock,
plus, to the extent not paid by the Corporation, an additional amount equivalent
to the Dividend Amount. In the event of the exercise of the Liquidation Call
Right by SMTC Nova Scotia in accordance with these share provisions, each holder
of Exchangeable Shares (other than SMTC or any Affiliate of SMTC) shall be
obligated to sell all of the Exchangeable Shares held by the holder to SMTC Nova
Scotia on the Company Liquidation Date and, upon payment by SMTC Nova Scotia to
the holder of the Liquidation Call Purchase Price for each such share, the
Corporation shall have no obligation to pay the Company Liquidation Amount of
such shares so purchased by SMTC Nova Scotia. If SMTC Nova Scotia does not
exercise the Liquidation Call Right in the manner described above, on the
Company Liquidation Date the holders of the Exchangeable Shares will be entitled
to receive in exchange therefor the Company Liquidation Amount otherwise payable
by the Corporation in connection with the liquidation, dissolution or winding-up
of the Corporation pursuant to this Article 5.

5.5  To exercise the Liquidation Call Right, SMTC Nova Scotia must notify the
Transfer Agent, as agent for the holders of Exchangeable Shares, and the
Corporation of SMTC Nova Scotia's intention to exercise such right at least 45
days before the Company Liquidation Date

                                      -10-
<PAGE>

in the case of a voluntary liquidation, dissolution or winding-up of the
Corporation and at least five Business Days before the Company Liquidation Date
in the case of an involuntary liquidation, dissolution or winding-up of the
Corporation. The Transfer Agent will notify the holders of Exchangeable Shares
as to whether or not SMTC Nova Scotia has exercised the Liquidation Call Right
forthwith after the expiry of the period during which the same may be exercised
by SMTC Nova Scotia. If SMTC Nova Scotia exercises the Liquidation Call Right,
then on the Company Liquidation Date, SMTC Nova Scotia will purchase and holders
will sell all of the Exchangeable Shares then outstanding for a price per share
equal to the Liquidation Call Purchase Price.

5.6 For the purposes of completing the purchase of the Exchangeable Shares
pursuant to the exercise of the Liquidation Call Right, SMTC Nova Scotia shall
deposit with the Transfer Agent, on or before the Company Liquidation Date,
certificates representing the aggregate number of shares of SMTC Common Stock
deliverable by SMTC Nova Scotia pursuant to such exercise and a cheque or
cheques of SMTC Nova Scotia payable at par at any branch of the bankers of SMTC
Nova Scotia representing the aggregate Dividend Amount in payment of the total
Liquidation Call Purchase Price (without interest), less any amounts withheld
pursuant to Section 12.3. Provided that SMTC Nova Scotia has complied with the
immediately preceding sentence, on and after the Company Liquidation Date, the
rights of each holder of Exchangeable Shares will be limited to receiving such
holder's proportionate part of the total Liquidation Call Purchase Price payable
by SMTC Nova Scotia upon presentation and surrender by the holder of
certificates representing the Exchangeable Shares held by such holder and the
holder shall on and after the Company Liquidation Date be considered and deemed
for all purposes to be the holder of the shares of SMTC Common Stock to which it
is entitled pursuant to the exercise of the Liquidation Call Right. Upon
surrender to the Transfer Agent of a certificate or certificates representing
Exchangeable Shares, together with such other documents and instruments as may
be required to effect a transfer of Exchangeable Shares under the OBCA and the
articles and by-laws of the Corporation and such additional documents and
instruments as the Transfer Agent may reasonably require, the holder of such
surrendered certificate or certificates shall be entitled to receive in exchange
therefor, and the Transfer Agent on behalf of SMTC Nova Scotia shall deliver to
such holder, certificates representing the number of shares of SMTC Common Stock
to which the holder is entitled pursuant to the exercise of the Liquidation Call
Right and a cheque or cheques of SMTC Nova Scotia payable at par at any branch
of the bankers of SMTC Nova Scotia in payment of the remaining portion, if any,
of the total Liquidation Call Purchase Price (without interest), less any
amounts withheld pursuant to Section 12.3.

                                   ARTICLE 6
                  RETRACTION OF EXCHANGEABLE SHARES BY HOLDER

6.1 A holder of Exchangeable Shares shall be entitled at any time, subject to
the exercise by SMTC Nova Scotia of the Retraction Call Right and otherwise upon
compliance with the provisions of this Article 6, to require the Corporation to
redeem any or all of the Exchangeable Shares registered in the name of such
holder for an amount per share equal to the Current Market Price of a share of
SMTC Common Stock on the last Business Day prior to the Retraction Date (the
"Retraction Price"), which shall be satisfied in full by the Corporation causing
to be delivered to such holder one share of SMTC Common Stock for each

                                      -11-
<PAGE>

Exchangeable Share presented and surrendered by the holder, together with, on
the payment date therefor, the Dividend Amount. To effect such redemption, the
holder shall present and surrender at the registered office of the Corporation
or at any office of the Transfer Agent as may be specified by the Corporation by
notice to the holders of Exchangeable Shares the certificate or certificates
representing the Exchangeable Shares which the holder desires to have the
Corporation redeem, together with such other documents and instruments as may be
required to effect a transfer of Exchangeable Shares under the OBCA and the
articles and bylaws of the Corporation and such additional documents and
instruments as the Transfer Agent, SMTC or the Corporation may reasonably
require, and together with a duly executed statement (the "Retraction Request")
in the form of Schedule "A" hereto or in such other form as may be acceptable to
the Corporation:

     (a)  specifying that the holder desires to have all or any number specified
          therein of the Exchangeable Shares represented by such certificate or
          certificates (the "Retracted Shares") redeemed by the Corporation;

     (b)  stating the Retraction Date, provided that in the event that a
          Retraction Date is not specified by the holder in the Retraction
          Request, the Retraction Date shall be deemed to be the fifteenth
          Business Day after the date on which the Retraction Request is
          received by the Corporation; and

     (c)  acknowledging the overriding right (the "Retraction Call Right") of
          SMTC Nova Scotia to purchase all but not less than all of the
          Retracted Shares directly from the holder and that the Retraction
          Request shall be deemed to be a revocable offer by the holder to sell
          all but not less than all of the Retracted Shares to SMTC Nova Scotia
          in accordance with the Retraction Call Right on the terms and
          conditions set out in Section 6.3 of these share provisions.

6.2 Subject to the exercise by SMTC Nova Scotia of the Retraction Call Right,
upon receipt by the Corporation or the Transfer Agent in the manner specified in
Section 6.1 of a certificate or certificates representing the number of
Retracted Shares, together with a Retraction Request, and provided that the
Retraction Request is not revoked by the holder in the manner specified in
Section 6.7, the Corporation shall redeem the Retracted Shares effective at the
close of business on the Retraction Date and shall cause to be delivered to such
holder the total Retraction Price with respect to such shares, provided that all
declared and unpaid dividends for which the record date has occurred prior to
the Retraction Date shall be paid to the holder on the payment date for such
dividends. If only a part of the Exchangeable Shares represented by any
certificate is redeemed (or purchased by SMTC Nova Scotia pursuant to the
Retraction Call Right), a new certificate for the balance of such Exchangeable
Shares shall be issued to the holder at the expense of the Corporation.

6.3 Upon receipt by the Corporation of a Retraction Request, the Corporation
shall immediately notify SMTC Nova Scotia thereof. In order to exercise the
Retraction Call Right, SMTC Nova Scotia must notify the Corporation of its
determination to do so (the "SMTC Nova Scotia Call Notice") within five Business
Days of notification to SMTC Nova Scotia by the Corporation of the receipt by
the Corporation of the Retraction Request. If SMTC Nova Scotia does not so
notify the Corporation within such five Business Day period,

                                      -12-
<PAGE>

the Corporation will notify the holder as soon as possible thereafter that SMTC
Nova Scotia will not exercise the Retraction Call Right. If SMTC Nova Scotia
delivers the SMTC Nova Scotia Call Notice within such five Business Day period,
and provided that the Retraction Request is not revoked by the holder in the
manner specified in Section 6.7, the Retraction Request shall thereupon be
considered only to be an offer by the holder to sell the Retracted Shares to
SMTC Nova Scotia in accordance with the Retraction Call Right. In such event,
the Corporation shall not redeem the Retracted Shares and SMTC Nova Scotia shall
purchase from such holder and such holder shall sell to SMTC Nova Scotia on the
Retraction Date the Retracted Shares for a purchase price (the "Purchase Price")
per share equal to the Retraction Price per share, plus, on the designated
payment date therefor, to the extent not paid by the Corporation on the
designated payment date therefor, an additional amount equivalent to the
Dividend Amount. To the extent that SMTC Nova Scotia pays the Dividend Amount in
respect of the Retracted Shares, the Corporation shall no longer be obligated to
pay any declared and unpaid dividends on such Retracted Shares. For the purposes
of completing a purchase pursuant to the Retraction Call Right, SMTC Nova Scotia
shall deposit with the Transfer Agent, on or before the Retraction Date,
certificates representing shares of SMTC Common Stock registered in the name of
the holder or in such other name as the holder may request, and a cheque or
cheques of SMTC Nova Scotia payable at par at any branch of the bankers of SMTC
Nova Scotia representing the aggregate Dividend Amount (without interest), less
any amounts pursuant to Section 12.3. Provided that SMTC Nova Scotia has
complied with the immediately preceding sentence, the closing of the purchase
and sale of the Retracted Shares pursuant to the Retraction Call Right shall be
deemed to have occurred as at the close of business on the Retraction Date and,
for greater certainty, no redemption by the Corporation of such Retracted Shares
shall take place on the Retraction Date. In the event that SMTC Nova Scotia does
not deliver an SMTC Nova Scotia Call Notice within such five Business Day
period, and provided that the Retraction Request is not revoked by the holder in
the manner specified in Section 6.7, the Corporation shall redeem the Retracted
Shares on the Retraction Date and in the manner otherwise contemplated in this
Article 6.

6.4 The Corporation or SMTC Nova Scotia, as the case may be, shall deliver or
cause the Transfer Agent to deliver to the relevant holder, at the address of
the holder recorded in the securities register of the Corporation for the
Exchangeable Shares or at the address specified in the holder's Retraction
Request or by holding for pick-up by the holder at the registered office of the
Corporation or at any office of the Transfer Agent as may be specified by the
Corporation by notice to the holders of Exchangeable Shares, certificates
representing shares of SMTC Common Stock registered in the name of the holder or
in such other name as the holder may request, and, if applicable and on or
before the payment date therefor, a cheque payable at par at any branch of the
bankers of the Corporation or SMTC Nova Scotia, as applicable, representing the
aggregate Dividend Amount in payment of the total Retraction Price or the total
Purchase Price, as the case may be (without interest), in each case, less any
amounts withheld pursuant to Section 12.3, and such delivery of such
certificates and cheques on behalf of the Corporation or by SMTC Nova Scotia, as
the case may be, or by the Transfer Agent shall be deemed to be payment of and
shall satisfy and discharge all liability for the total Retraction Price or
total Purchase Price, as the case may be, to the extent that the same is
represented by such share certificates and cheques.

                                      -13-
<PAGE>

6.5 On and after the close of business on the Retraction Date, the holder of the
Retracted Shares shall cease to be a holder of such Retracted Shares and shall
not be entitled to exercise any of the rights of a holder in respect thereof,
other than the right to receive its proportionate part of the total Retraction
Price or total Purchase Price, as the case may be, unless upon presentation and
surrender of certificates in accordance with the foregoing provisions, payment
of the total Retraction Price or the total Purchase Price, as the case may be,
shall not be made as provided in Section 6.4, in which case the rights of such
holder shall remain unaffected until the total Retraction Price or the total
Purchase Price, as the case may be, has been paid in the manner hereinbefore
provided. On and after the close of business on the Retraction Date, provided
that presentation and surrender of certificates and payment of the total
Retraction Price or the total Purchase Price, as the case may be, has been made
in accordance with the foregoing provisions, the holder of the Retracted Shares
so redeemed by the Corporation or purchased by SMTC Nova Scotia shall thereafter
be considered and deemed for all purposes to be a holder of the shares of SMTC
Common Stock delivered to it.

6.6 Notwithstanding any other provision of this Article 6, the Corporation shall
not be obligated to redeem Retracted Shares specified by a holder in a
Retraction Request to the extent that such redemption of Retracted Shares would
be contrary to solvency requirements or other provisions of applicable law. If
the Corporation believes that on any Retraction Date it would not be permitted
by any of such provisions to redeem the Retracted Shares tendered for redemption
on such date, and provided that SMTC Nova Scotia shall not have exercised the
Retraction Call Right with respect to the Retracted Shares, the Corporation
shall only be obligated to redeem Retracted Shares specified by a holder in a
Retraction Request to the extent of the maximum number that may be so redeemed
(rounded down to the nearest whole number of shares) as would not be contrary to
such provisions and shall notify the holder and the Trustee at least two
Business Days prior to the Retraction Date as to the number of Retracted Shares
which will not be redeemed by the Corporation. In any case in which the
redemption by the Corporation of Retracted Shares would be contrary to solvency
requirements or other provisions of applicable law, the Corporation shall redeem
the maximum number of Exchangeable Shares which the Board of Directors
determines the Corporation is, on the Retraction Date, permitted to redeem,
which shall be selected as nearly as may be pro rata (disregarding fractions) in
proportion to the total number of Exchangeable Shares tendered for retraction by
holders thereof and the Corporation shall issue to each holder of Retracted
Shares a new certificate, at the expense of the Corporation, representing the
Retracted Shares not redeemed by the Corporation pursuant to Section 6.2.
Provided that the Retraction Request is not revoked by the holder in the manner
specified in Section 6.7 and provided further that SMTC Nova Scotia shall not
have exercised the Retraction Call Right with respect to the Retracted Shares,
the holder of any such Retracted Shares not redeemed by the Corporation pursuant
to Section 6.2 as a result of solvency requirements or other provisions of
applicable law shall be deemed, by giving the Retraction Request, to have
instructed the Trustee to require SMTC to purchase such Retracted Shares from
such holder on the Retraction Date or as soon as practicable thereafter on
payment by SMTC to such holder of the Purchase Price for each such Retracted
Share, all as more specifically provided in the Voting and Exchange Trust
Agreement.

6.7 A holder of Retracted Shares may by notice in writing given by the holder to
the Corporation before the close of business on the Business Day immediately
preceding the

                                      -14-
<PAGE>

Retraction Date, withdraw its Retraction Request, in which event such Retraction
Request shall be null and void and, for greater certainty, the revocable offer
constituted by the Retraction Request to sell the Retracted Shares to SMTC Nova
Scotia and the instruction to the Trustee to require SMTC to purchase such
Retracted Shares shall each be deemed to have been revoked.

                                   ARTICLE 7
                       REDEMPTION OF EXCHANGEABLE SHARES

7.1 Subject to applicable law, and provided that SMTC Nova Scotia has not
exercised the Redemption Call Right, the Corporation shall, on the Redemption
Date, redeem all but not less than all of the then outstanding Exchangeable
Shares for an amount per share equal to the Current Market Price of one share of
SMTC Common Stock on the last Business Day prior to the Redemption Date (the
"Redemption Price"), which shall be satisfied in full by the Corporation causing
to be delivered to each holder of Exchangeable Shares one share of SMTC Common
Stock for each Exchangeable Share held by such holder, together with the
Dividend Amount.

7.2 In any case of a redemption of Exchangeable Shares under this Article 7, the
Corporation shall, at least 60 days before the Redemption Date (other than a
Redemption Date established in connection with an SMTC Control Transaction, an
Exchangeable Share Voting Event or an Exempt Exchangeable Share Voting Event),
send or cause to be sent to each holder of Exchangeable Shares a notice in
writing of the redemption by the Corporation or the purchase by SMTC Nova Scotia
under the Redemption Call Right, as the case may be, of the Exchangeable Shares
held by such holder. In the case of a Redemption Date established in connection
with an SMTC Control Transaction, an Exchangeable Share Voting Event or an
Exempt Exchangeable Share Voting Event, the written notice of redemption by the
Corporation or the purchase by SMTC Nova Scotia under the Redemption Call Right
will be sent on or before the Redemption Date, on as many days' prior written
notice as may be determined by the Board of Directors to be reasonably
practicable in the circumstances. In any such case, such notice shall set out
the Redemption Price, as the case may be, the Redemption Date and, if
applicable, particulars of the Redemption Call Right.

7.3 On or after the Redemption Date and subject to the exercise by SMTC Nova
Scotia of the Redemption Call Right, the Corporation shall cause to be delivered
to the holders of the Exchangeable Shares to be redeemed the Redemption Price
for each such Exchangeable Share, together with the Dividend Amount, upon
presentation and surrender at the registered office of the Corporation or at any
office of the Transfer Agent as may be specified by the Corporation in such
notice of the certificates representing such Exchangeable Shares, together with
such other documents and instruments as may be required to effect a transfer of
Exchangeable Shares under the OBCA and the articles and bylaws of the
Corporation and such additional documents and instruments as the Transfer Agent,
SMTC or the Corporation may reasonably require. Payment of the total Redemption
Price for such Exchangeable Shares, together with payment of such dividends,
shall be made by delivery to each holder, at the address of the holder recorded
in the securities register of the Corporation or by holding for pick-up by the
holder at the registered office of the Corporation or at any office of the
Transfer Agent as may be specified by the Corporation in such notice, on behalf
of the Corporation, certificates representing shares of SMTC Common Stock and,
if applicable, a cheque of the Corporation

                                      -15-
<PAGE>

payable at par at any branch of the bankers of the Corporation in payment of any
such dividends (without interest), in each case, less any amounts withheld
pursuant to Section 12.3. On and after the Redemption Date, the holders of the
Exchangeable Shares called for redemption shall cease to be holders of such
Exchangeable Shares and shall not be entitled to exercise any of the rights of
holders in respect thereof, other than the right to receive their proportionate
part of the total Redemption Price and any such dividends, unless payment of the
total Redemption Price and any such dividends for such Exchangeable Shares shall
not be made upon presentation and surrender of certificates in accordance with
the foregoing provisions, in which case the rights of the holders shall remain
unaffected until the total Redemption Price and any such dividends have been
paid in the manner hereinbefore provided. The Corporation shall have the right
at any time after the sending of a notice of its intention to redeem the
Exchangeable Shares as aforesaid to deposit or cause to be deposited the total
Redemption Price for and the full amount of such dividends on (except as
provided in the preceding sentence) the Exchangeable Shares so called for
redemption, or of such Exchangeable Shares represented by certificates that have
not at the date of such deposit been surrendered by the holders thereof in
connection with such redemption, in a custodial account with any chartered bank
or trust company in Canada named in such notice (without interest), less any
amounts withheld pursuant to Section 12.3. Upon the later of such deposit being
made and the Redemption Date, the Exchangeable Shares in respect whereof such
deposit shall have been made shall be redeemed and the rights of the holders
thereof after such deposit or Redemption Date, as the case may be, shall be
limited to receiving their proportionate part of the total Redemption Price and
such dividends for such Exchangeable Shares so deposited (without interest),
against presentation and surrender of the said certificates held by them,
respectively, in accordance with the foregoing provisions. Upon such payment or
deposit of the total Redemption Price and the full amount of such dividends, the
holders of the Exchangeable Shares shall thereafter be considered and deemed for
all purposes to be holders of the SMTC Common Stock delivered to them or to the
custodian on their behalf.

7.4 SMTC Nova Scotia shall have the overriding right (the "Redemption Call
Right"), notwithstanding the proposed redemption of Exchangeable Shares by the
Corporation pursuant to these share provisions, to purchase from all but not
less than all of the holders of Exchangeable Shares (other than any holder of
Exchangeable Shares which is SMTC or an Affiliate of SMTC) on the Redemption
Date all but not less than all of the Exchangeable Shares held by each such
holder on payment by SMTC Nova Scotia to each holder of an amount per
Exchangeable Share (the "Redemption Call Purchase Price") equal to the Current
Market Price of a share of SMTC Common Stock on the last Business Day prior to
the Redemption Date, which shall be satisfied in full by SMTC Nova Scotia
causing to be delivered to such holder one share of SMTC Common Stock, plus, to
the extent not paid by the Corporation, an additional amount equivalent to the
Dividend Amount. In the event of the exercise of the Redemption Call Right by
SMTC Nova Scotia, each holder shall be obligated to sell all of the Exchangeable
Shares held by the holder to SMTC Nova Scotia on the Redemption Date and, upon
payment by SMTC Nova Scotia to the holder of the Redemption Call Purchase Price
for each such share, the Corporation shall have no obligation to redeem such
shares so purchased by SMTC Nova Scotia or to pay the Redemption Price in
respect thereof. If SMTC Nova Scotia does not exercise the Redemption Call Right
in the manner described above, on the Redemption Date the holders of the
Exchangeable Shares will be entitled to receive in

                                      -16-
<PAGE>

exchange therefor the Redemption Price otherwise payable by the Corporation in
connection with the redemption of Exchangeable Shares pursuant to this Article
7.

7.5 To exercise the Redemption Call Right, SMTC Nova Scotia must notify the
Transfer Agent, as agent for the holders of Exchangeable Shares, and the
Corporation of SMTC Nova Scotia's intention to exercise such right at least 60
days before the Redemption Date, except in the case of a redemption occurring as
a result of an SMTC Control Transaction, an Exchangeable Share Voting Event or
an Exempt Exchangeable Share Voting Event, in which case SMTC Nova Scotia shall
so notify the Transfer Agent and the Corporation on or before the Redemption
Date. The Transfer Agent will notify the holders of Exchangeable Shares as to
whether or not SMTC Nova Scotia has exercised the Redemption Call Right
forthwith after the expiry of the period during which the same may be exercised
by SMTC Nova Scotia. If SMTC Nova Scotia exercises the Redemption Call Right,
then on the Redemption Date, SMTC Nova Scotia will purchase and the holders will
sell all of the Exchangeable Shares then outstanding for a price per share equal
to the Redemption Call Purchase Price.

7.6 For the purposes of completing the purchase of the Exchangeable Shares
pursuant to the exercise of the Redemption Call Right, SMTC Nova Scotia shall
deposit with the Transfer Agent, on or before the Redemption Date, certificates
representing the aggregate number of shares of SMTC Common Stock deliverable by
SMTC Nova Scotia pursuant to such exercise and a cheque or cheques of SMTC Nova
Scotia payable at par at any branch of the bankers of SMTC Nova Scotia
representing the aggregate Dividend Amount in payment of the total Redemption
Call Purchase Price (without interest), less any amounts withheld pursuant to
Section 12.3. Provided that SMTC Nova Scotia has complied with the immediately
preceding sentence, on and after the Redemption Date, the rights of each holder
of Exchangeable Shares will be limited to receiving such holder's proportionate
part of the total Redemption Call Purchase Price payable by SMTC Nova Scotia
upon presentation and surrender by the holder of certificates representing the
Exchangeable Shares held by such holder and the holder shall on and after the
Redemption Date be considered and deemed for all purposes to be the holder of
the shares of SMTC Common Stock to which it is entitled pursuant to the exercise
of the Redemption Call Right. Upon surrender to the Transfer Agent of a
certificate or certificates representing Exchangeable Shares, together with such
other documents and instruments as may be required to effect a transfer of
Exchangeable Shares under the OBCA and the articles and by-laws of the
Corporation and such additional documents and instruments as the Transfer Agent
may reasonably require, the holder of such surrendered certificate or
certificates shall be entitled to receive in exchange therefor, and the Transfer
Agent on behalf of SMTC Nova Scotia shall deliver to such holder, certificates
representing shares of SMTC Common Stock to which the holder is entitled
pursuant to the exercise of the Redemption Call Right and a cheque or cheques of
SMTC Nova Scotia payable at par at any branch of the bankers of SMTC Nova Scotia
in payment of the remaining portion, if any, of the total Redemption Call
Purchase Price (without interest), less any amounts withheld pursuant to Section
12.3.

                                   ARTICLE 8
                           PURCHASE FOR CANCELLATION

8.1 Subject to applicable law and the articles of the Corporation, the
Corporation may at any time and from time to time purchase for cancellation all
or any part of the outstanding

                                      -17-
<PAGE>

Exchangeable Shares at any price by tender to all the holders of record of
Exchangeable Shares then outstanding or through the facilities of any stock
exchange or stock quotation system on which the Exchangeable Shares are then
listed or quoted at any price per share, together with an amount equal to the
Dividend Amount. If in response to an invitation for tenders under the
provisions of this Section 8.1, more Exchangeable Shares are tendered at a price
or prices acceptable to the Corporation than the Corporation is prepared to
purchase, the Exchangeable Shares to be purchased by the Corporation shall be
purchased as nearly as may be pro rata according to the number of shares
tendered by each holder who submits a tender to the Corporation, provided that
when shares are tendered at different prices, the pro rating shall be effected
(disregarding fractions) only with respect to the shares tendered at the price
at which more shares were tendered than the Corporation is prepared to purchase
after the Corporation has purchased all the shares tendered at lower prices. If
only part of the Exchangeable Shares represented by any certificate shall be
purchased, a new certificate for the balance of such shares shall be issued at
the expense of the Corporation.

                                  ARTICLE 9
                                 VOTING RIGHTS

9.1 Except as required by applicable law and by Article 10, Section 11.1 and

                 ACTIONS BY THE CORPORATION AND ITS AFFILIATES

12.1 The Corporation will take all such actions and do all such things as shall
be necessary or advisable to perform and comply with and to ensure performance
and compliance by SMTC, SMTC Nova Scotia and the Corporation with all provisions
of the Exchangeable Share Support Agreement applicable to SMTC, SMTC Nova Scotia
and the Corporation, respectively, in accordance with the terms thereof

Corporation under or pursuant to such agreement.

12.2 The Corporation shall not propose, agree to or otherwise give effect to any
amendment to, or waiver or forgiveness of its rights or obligations under, the
Exchangeable Share Support Agreement without the approval of the holders of the
Exchangeable Shares given in accordance with Section 10.2 of these share

          Board of Directors shall be of the good faith opinion, after
          consultation with counsel, that such provisions and modifications will
          not be prejudicial to the interests of the holders of the Exchangeable
          Shares; or

     (c)  making such changes in or corrections to such agreement which, on the

12.3 The Corporation, SMTC Nova Scotia, SMTC and the Transfer Agent shall be

with respect to such payment under the Income Tax Act (Canada), the United
States Internal Revenue Code of 1986 or any provision of provincial, state,
local or foreign tax law, in each case, as amended. To the extent that amounts
are so withheld, such withheld amounts shall be treated for all purposes hereof
as having been paid to the holder of the Exchangeable Shares in respect of which
such deduction and withholding was made, provided that such withheld amounts are
actually remitted to the appropriate taxing authority. To the extent that the
amount so required or permitted to be deducted or withheld from any payment to a
holder exceeds the cash portion of the consideration otherwise payable to the
holder, the Corporation, SMTC Nova Scotia, SMTC and the Transfer Agent are
hereby authorized to sell or otherwise dispose of such portion of the
consideration as is necessary to provide sufficient funds to the Corporation,
SMTC Nova Scotia, SMTC or the Transfer Agent, as the case may be, to enable it
to comply with such deduction or withholding requirement and the Corporation,
SMTC Nova Scotia, SMTC or the Transfer Agent shall notify the holder thereof and
remit to such holder any unapplied balance of the net proceeds of such sale.

Corporation, SMTC Nova Scotia, or SMTC to any holder of Exchangeable Shares in
accordance with these share provisions shall be duly issued as fully paid and
non-assessable and shall be free and clear of any lien, claim or encumbrance.

13.2 Each holder of an Exchangeable Share, whether of record or beneficial, by
virtue of becoming and being such a holder shall be deemed to acknowledge each
of the Liquidation Call Right, the Retraction Call Right and the Redemption Call
Right, in each case, in favour of SMTC Nova Scotia, and the overriding nature
thereof in connection with the liquidation, dissolution or winding-up of the
Corporation or the retraction or redemption of Exchangeable Shares, as the case

by a holder of Exchangeable Shares shall be in writing and shall be valid and
effective if given by mail (postage prepaid) or by fax or by delivery to the
registered office of the Corporation and addressed to the attention of the
President of the Corporation. Any such notice, request or other communication,
if given by mail, fax or delivery, shall only be deemed to have been given and
received upon actual receipt thereof by the Corporation.

Corporation or the Transfer Agent of certificates representing Exchangeable
Shares in connection with the liquidation, dissolution or winding-up of the
Corporation or the retraction or redemption of Exchangeable Shares shall be made
by ordinary mail (postage prepaid) or by delivery to the registered office of
the Corporation or to such office of the Transfer Agent as may be specified by
the Corporation, in each case, addressed to the attention of the President of

interrupted at the time when the Corporation is required or elects to give any
notice to the holders of Exchangeable Shares hereunder, the Corporation shall,

in The Globe and Mail, national edition, or any other English language daily
newspaper or newspapers of general circulation in Canada and in a French
language daily newspaper of general circulation in the Province of Quebec, once
in each of two successive weeks, and notice so published shall be deemed to have
been given on the latest date on which the first publication has taken place.

     If, by reason of any actual or threatened interruption of mail service due
to strike, lockout or otherwise, any notice to be given to the Corporation would
be unlikely to reach its destination in a timely manner, such notice shall be
valid and effective only if delivered personally to the Corporation in
accordance with Section 14.1 or 14.2, as the case may be.
