|3.5 | Assumption by Transferee
|--- | ------------------------



Upon becoming a Warrantholder in accordance with the provisions of this Indenture, the transferee thereof shall be deemed to have acknowledged and agreed
to be bound by this Indenture. Upon the registration by the Trustee of such transferee as the holder of a Share Purchase Warrant, the transferor thereof shall cease to have any further rights under this Indenture with respect to such Share Purchase
Warrant or any Exchangeable Shares to be issued on exercise.



ARTICLE 4

EXERCISE OF SHARE PURCHASE WARRANTS



|4.1 | Exercise
|--- | --------



|(1) | Subject to the limitation set forth in Subsection 4.1(2) and Section 4.5, holders of Share Purchase Warrants may at any time prior to the Expiry Time exercise the right thereby
conferred to be issued Exchangeable Shares by surrendering to the Trustee at its principal office in Toronto, Ontario or to any other person or at any other place designated by SMTC Canada with the approval of the Trustee, during normal business
hours on a business day at such place:
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (a) | a certified cheque or bank draft payable to SMTC Canada in the amount of the Exercise Price in respect of each Exchangeable Share to be issued;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | the Share Purchase Warrant Certificate evidencing such Share Purchase Warrants; and
| | --- | -----------------------------------------------------------------------------------



| | (c) | a duly completed and executed notice of exercise substantially in the form set out in Appendix 1 to such Share Purchase Warrant Certificate,
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------



provided such notice is also given to SMTC Canada by either the
Warrantholder or the Trustee by delivering to SMTC Canada a copy of such documents. Notwithstanding the foregoing, a holder may exercise the Share Purchase Warrants by delivering to the Trustee a facsimile transmission of the Share Purchase Warrant
Certificate(s) evidencing such Share Purchase Warrants together with a duly completed and executed notice of exercise in the form set out in Appendix 1 to such Share Purchase Warrant Certificate(s) provided that the original Share Purchase Warrant
Certificate(s) and notice of exercise are received by the Trustee or other person as may be designated herein within three business days of the date of such facsimile transmission.



|(2) | Any certified cheque or bank draft, Share Purchase Warrant Certificate or notice of exercise referred to in Subsection 4.1(1) will be deemed to have been surrendered only on
personal delivery thereof to, or, if sent by mail or other means of transmission, on actual
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 15 -



---

| | receipt thereof by, the Trustee or one of the other persons at the office or one of the other places specified in Subsection 4.1(1), provided however that if exercise is made by
facsimile transmission as set out in Subsection 4.1(1), the Share Purchase Warrant Certificate and executed notice of exercise will be deemed to be surrendered as of the date of the facsimile transmission only in the event that the original Share
Purchase Warrant Certificate and executed notice are received by the Trustee or other person as designated herein within three business days of the date of the facsimile transmission.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(3) | Any notice of exercise referred to in Subsection 4.1(1) must be signed by the Warrantholder, or such Warrantholders executors, administrators or other legal representatives or
his or their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Trustee, acting reasonably, and, if any Exchangeable Shares thereby issuable are to be issued to a person or persons other than the
Warrantholder and must specify the name or names and the address or addresses of each such person or persons and the number of Exchangeable Shares to be issued to each such person if more than one is so specified.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(4) | Any issuance of Exchangeable Shares upon exercise of Share Purchase Warrants must be in accordance with applicable law (as determined by SMTC Canada).
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------



|(5) | The holder of any Share Purchase Warrant Certificate who wishes to exercise the Share Purchase Warrants evidenced by such Share Purchase Warrant Certificate may exercise less than
all of such Share Purchase Warrants and in the case of any such partial exercise shall be entitled to receive, without charge therefor, a Share Purchase Warrant Certificate, in form, signed and certified in accordance with the provisions of Article
2, evidencing the number of Share Purchase Warrants held by the Warrantholder which remain unexercised. Such Share Purchase Warrant Certificate will be delivered by the Trustee to the holder concurrently with the certificates representing the
Exchangeable Shares issued on partial exercise of such holders Share Purchase Warrants.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.2 | Effect of Exercise
|--- | ------------------



|(1) | Upon the exercise of any Share Purchase Warrant in accordance with Section 4.1, the Exchangeable Shares thereby issuable will be deemed to have been issued, and the person or
persons to whom such Exchangeable Shares are to be issued will be deemed to have become the holder or holders of record thereof on the Exercise Date, unless the transfer registers for the Exchangeable Shares are closed on that date, in which case
such Exchangeable Shares will be deemed to have been issued and such person or persons will be deemed to have become the holder or holders of record thereof on the date on which such transfer registers are reopened, but such Exchangeable Shares will
be issued on the basis of the number of Exchangeable Shares to which such person or persons were entitled on the Exercise Date.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | As soon as practicable and in any event not later than the fifth business day on which the transfer registers for the Exchangeable Shares have been open after such exercise, SMTC
Canada will cause the Trustee to mail to the person or persons in whose name or names the Exchangeable Shares thereby issued have been issued, at his or their respective addresses, or, if so specified, cause to be delivered to such person or persons
at the place where the Share Purchase Warrant Certificate evidencing such Share Purchase Warrant was surrendered, certificates representing the Exchangeable Shares so issued.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 16 -



---

|(3) | If any Exchangeable Shares issuable pursuant to any Share Purchase Warrant are to be issued to a person or persons other than the Warrantholder, the Warrantholder must pay to SMTC
Canada or to the Trustee on its behalf an amount equal to all exigible transfer taxes or other government charges, and SMTC Canada will not be required to issue or deliver any certificates representing any such Exchangeable Shares unless or until
such amount has been so paid or the Warrantholder has established to the satisfaction of SMTC Canada that such taxes and charges have been paid or that no such taxes or charges are owing.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.3 | No Fractional Exchangeable Shares
|--- | ---------------------------------



SMTC Canada shall not be required to issue fractional Exchangeable Shares upon the exercise of Share Purchase Warrants. To the extent that a holder of
Share Purchase Warrants would otherwise have been entitled to receive, on the exercise of Share Purchase Warrants, a fraction of an Exchangeable Share, such right may only be exercised in respect of such fraction in connection with another Share
Purchase Warrant or Share Purchase Warrants which in the aggregate entitle the holder to receive a whole number of Exchangeable Shares. If a Warrantholder is not able to combine Share Purchase Warrants so as to be entitled to acquire a whole number
of Exchangeable Shares, the number of Exchangeable Shares which such Warrantholder is entitled to receive upon exercise of Share Purchase Warrants shall be rounded up to the nearest whole number.



|4.4 | Recording
|--- | ---------



The Trustee will record particulars of each Share Purchase Warrant exercised which will include the name and address of each person to whom Exchangeable
Shares are thereby issued, the number of Exchangeable Shares so issued and the Exercise Date in respect thereof. Within five business days after each Exercise Date the Trustee will provide such particulars in writing to SMTC Canada.



|4.5 | Securities Restrictions
|--- | -----------------------



|(1) | No Exchangeable Shares will be issued on exercise of any Share Purchase Warrant, if in the opinion of counsel to SMTC Canada (delivered to the Trustee prior to issue), the issuance
of such Exchangeable Shares would constitute a violation of the securities laws of any applicable jurisdiction or require SMTC Canada to qualify the Exchangeable Shares issuable upon exercise of the Share Purchase Warrants for distribution in any
jurisdiction other than the Qualifying Jurisdictions. Without limiting the generality of the previous sentence, if any Share Purchase Warrant is exercised before the Prospectus Qualification Date, the certificates representing Exchangeable Shares
thereby issued will bear such legends as may, in the opinion of counsel to SMTC Canada, be necessary or advisable in order to avoid a violation of any applicable securities laws of any province or territory of Canada, of the United States of America
or any jurisdiction or to comply with the requirements of any stock exchange on which the Exchangeable Shares are then listed, provided that if, at any time, in the opinion of counsel to SMTC Canada, such legends are no longer necessary or advisable
in order to avoid a violation of any such
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

---

| | laws or requirements, or the holder of any such legended certificate, at his expense, provides SMTC Canada with evidence reasonably satisfactory in form and substance to SMTC Canada
(which may include an opinion of counsel reasonably satisfactory to SMTC Canada) to the effect that such holder is entitled to sell or otherwise transfer such Exchangeable Shares in a transaction in which such legends are not required, such legended
certificate may thereafter be surrendered to SMTC Canada in exchange for a certificate which does not bear such legends.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



ARTICLE 5

ADJUSTMENTS



|5.1 | Definitions
|--- | -----------



|(1) | The rights of the holder of any Share Purchase Warrant, including the number of Exchangeable Shares issuable upon the exercise of such Share Purchase Warrant and the Exercise Price
payable on exercise of such Share Purchase Warrant, will be adjusted from time to time in the events and in the manner provided in, and in accordance with this Article 5 and for such purposes:
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (a) | Adjustment Period means in respect of each Share Purchase Warrant, the period commencing on the Issue Date thereof and ending at the Expiry Time;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Current Market Price, on any date, means the average, during the period of 20 consecutive Trading Days ending on the second Trading Day before such date, of the
average of the high and low prices per share at which the Exchangeable Shares have traded on such stock exchange on which the Exchangeable Shares are listed as may be selected for that purpose by the directors or, if the Exchangeable Shares have not
been listed on a stock exchange for such number of Trading Days, then such lesser number of Trading Days as the Exchangeable Shares have been so listed, or, if the Exchangeable Shares are not listed on any stock exchange, then in the
over-the-counter market as reported by such other stock exchange or as quoted by the most commonly quoted or carried source of quotations for shares traded in the over-the-counter market, provided that if, on any such Trading Day, there are no such
reported or quoted high and low prices, the average of the closing bid and asked prices per share for board lots of the Exchangeable Shares reported by such stock exchange or as quoted by the most commonly quoted or carried source of quotations for
shares traded in the over-the-counter market, for such Trading Day shall be utilized in computing such average, and provided further that if the Exchangeable Shares are not listed on any stock exchange or traded in any over-the-counter market, then
the Current Market Price of the Exchangeable Shares shall be determined by the directors;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Exchange Rate means the rate at which Exchangeable Shares are issuable upon the exercise of any Share Purchase Warrant, which rate, subject to adjustment in
accordance with this Indenture, is one Exchangeable Share for each Share Purchase Warrant as of the Effective Date;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | Trading Day, with respect to any stock exchange or over-the-counter market, means a day on which shares may be traded through the facilities of such stock
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------



- 18 -



---

| |  | exchange or in such over-the-counter market, and, otherwise, means a day on which shares may be traded through the facilities of the principal stock exchange on which the
Exchangeable Shares are listed (or, if the Exchangeable Shares are not listed on any stock exchange, then in the over-the-counter market).
| |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5.2 | Adjustment of Exchange Rate
|--- | ---------------------------



|(1) | The Exchange Rate in effect at any date will be subject to adjustment from time to time and whenever at any time during the Adjustment Period, SMTC Canada shall (i) subdivide or
redivide the outstanding Exchangeable Shares into a greater number of Exchangeable Shares, (ii) consolidate, combine or reduce the outstanding Exchangeable Shares into a lesser number of Exchangeable Shares, or (iii) issue Exchangeable Shares or
other securities of SMTC Canada that are convertible into Exchangeable Shares (convertible securities) to all or substantially all of the holders of Exchangeable Shares or convertible securities (as the case may be) by way of a stock
dividend or other distribution. In any such event, the Exchange Rate will, on the effective date of such event, be adjusted so that it will equal the rate determined by multiplying the Exchange Rate in effect immediately prior to such date by a
fraction, of which the denominator shall be the total number of Exchangeable Shares outstanding on such date before giving effect to such event, and of which the numerator shall be the total number of Exchangeable Shares outstanding on such date
after giving effect to such event. Such adjustment will be made successively whenever any such event shall occur and any such issue of Exchangeable Shares or convertible securities by way of a stock dividend is deemed to have occurred on the record
date for the stock dividend for the purpose of calculating the number of outstanding Exchangeable Shares under this Subsection 5.2(1). To the extent that this Subsection 5.2(1) has become operative because of an issue of convertible securities
referred to in clause (iii) above, the number of Exchangeable Shares obtainable under each Share Purchase Warrant shall be readjusted based on the number of Exchangeable Shares issuable upon conversion or exchange of such convertible or exchangeable
securities.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | If and whenever at any time during the Adjustment Period, there is (i) any reclassification of the Exchangeable Shares at any time outstanding, any change of the Exchangeable Shares
into other shares or any other capital reorganization of SMTC Canada (other than as described in Subsection 5.2(1)), (ii) any consolidation, amalgamation, arrangement, merger or other form of business combination of SMTC Canada with or into any
other corporation resulting in any reclassification of the outstanding Exchangeable Shares, any change of the Exchangeable Shares into other shares or any other capital reorganization of SMTC Canada, or (iii) any sale, lease, exchange or transfer of
the undertaking or assets of SMTC Canada as an entirety or substantially as an entirety to another corporation or entity, then, in each such event, each holder of any Share Purchase Warrant which is thereafter exercised will be entitled to receive,
and shall accept, in lieu of the number of Exchangeable Shares to which such holder was theretofore entitled upon such exercise, the kind and number or amount of shares or other securities or property which such holder would have been entitled to
receive as a result of such event if, on the effective date thereof, such holder had been the registered holder of the number of Exchangeable Shares to which such holder was theretofore entitled upon such exercise. If necessary as a result of any
such event, appropriate adjustments will be made
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | in the application of the provisions set forth in this Article 5 with respect to the rights and interests thereafter of the holders of Share Purchase Warrants to the end that the
provisions set forth in this Article 5 will thereafter correspondingly be made applicable, as nearly as may reasonably be possible, in the relation to any shares or other securities or property thereafter deliverable upon the exercise or deemed
exercise of any Share Purchase Warrant. Any such adjustments will be made by and set forth in an indenture supplemental hereto approved by the directors and shall for all purposes be conclusively deemed to be an appropriate adjustment.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5.3 | Adjustment of Exercise Price
|--- | ----------------------------



|(1) | The Exercise Price in effect at any date will be subject to adjustment from time to time if and whenever at any time during the Adjustment Period, SMTC Canada shall (i) subdivide or
redivide the outstanding Exchangeable Shares into a greater number of Exchangeable Shares, (ii) consolidate, combine or reduce the outstanding Exchangeable Shares into a lesser number of Exchangeable Shares, or (iii) issue Exchangeable Shares to all
or substantially all of the holders of Exchangeable Shares by way of a stock dividend or other distribution. In any such event, the Exercise Price will, on the effective date of such event, be adjusted so that it will equal the price determined by
multiplying the Exercise Price in effect immediately prior to such date by a fraction, the numerator of which shall be the total number of Exchangeable Shares outstanding on such date before giving effect to such event and the denominator of which
shall be the total number of Exchangeable Shares outstanding immediately after giving effect to such event. Such adjustment will be made successively whenever any such event shall occur.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | If and whenever at any time during the Adjustment Period, SMTC Canada shall fix a record date for the issue of rights, options or warrants to all or substantially all of the holders
of Exchangeable Shares entitling the holders thereof, within a period expiring not more than 45 days after the date of the issue thereof, to subscribe for or purchase Exchangeable Shares (or securities convertible into or exchangeable for
Exchangeable Shares) at a price per share (or having a conversion or exchange price per share) less than 95% of the Current Market Price on the earlier of such record date and the date on which SMTC Canada announces its intention to make such
issuance, then, in each such case, the Exercise Price will be adjusted immediately after such record date so that it will equal the price determined by multiplying the Exercise Price in effect on such record date by a fraction, of which the
numerator shall be the total number of Exchangeable Shares outstanding on such record date plus a number of Exchangeable Shares equal to the number arrived at by dividing the aggregate price of the total number of additional Exchangeable Shares so
offered for subscription or purchase (or the aggregate conversion or exchange price of the convertible or exchangeable securities so offered) by such Current Market Price, and of which the denominator shall be the total number of Exchangeable Shares
outstanding on such record date plus the total number of additional Exchangeable Shares so offered for subscription or purchase (or into or for which the convertible or exchangeable securities so offered are convertible or exchangeable). If by the
terms of such rights, options or warrants, there is more than one purchase, conversion or exchange price per Exchangeable Share, the aggregate price of the total number of additional Exchangeable Shares offered for subscription or purchase, or the
additional conversion or exchange price of the convertible or exchangeable securities so offered,
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 20 -



---

| | shall be calculated for the purposes of the adjustment on the basis of the lowest purchase, conversion or exchange price per Exchangeable Share, as the case may be. Any Exchangeable
Shares owned by or held for the account of SMTC Canada or any affiliate or any subsidiary of SMTC Canada shall be deemed not to be outstanding for the purpose of any such computation. Such adjustment will be made successively whenever such a record
date is fixed, provided that if two or more such record dates or record dates referred to in Subsection 5.3(3) are fixed within a period of 25 Trading Days, such adjustment will be made successively as if each of such record dates occurred on the
earliest of such record dates. To the extent that any such rights, options or warrants are not so issued or any such rights, options or warrants are not exercised prior to the expiration thereof, the Exercise Price will then be readjusted to the
Exercise Price which would then be in effect if such record date had not been fixed or to the Exercise Price which would then be in effect based on the number of Exchangeable Shares (or securities convertible into or exchangeable for Exchangeable
Shares) actually issued upon the exercise of such rights, options or warrants, as the case may be.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(3) | If and whenever at any time during the Adjustment Period, SMTC Canada shall fix a record date for the making of a distribution to all or substantially all of the holders of
Exchangeable Shares of:
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (a) | shares of any class other than Exchangeable Shares whether of SMTC Canada or any other corporation;
| | --- | ---------------------------------------------------------------------------------------------------



| | (b) | rights, options or warrants (other than rights, options or warrants exercisable by the holders thereof within a period expiring not more than 45 days after the date of issue
thereof);
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | evidences of indebtedness; or
| | --- | -----------------------------



| | (d) | cash, securities or other property or assets;
| | --- | ---------------------------------------------



then, in each such case, the Exercise Price will be adjusted immediately after such record date so that it will equal the price determined by multiplying the Exercise
Price in effect on such record date by a fraction, of which the numerator shall be the total number of Exchangeable Shares outstanding on such record date multiplied by the Current Market Price on the earlier of such record date and the date on
which SMTC Canada announces its intention to make such distribution, less the aggregate fair market value (as determined by the directors at the time such distribution is authorized) of such shares or rights, options or warrants or evidences of
indebtedness or cash, securities or other property or assets so distributed, and of which the denominator shall be the total number of Exchangeable Shares outstanding on such record date multiplied by such Current Market Price. Any Exchangeable
Shares owned by or held for the account of SMTC Canada or any subsidiary of SMTC Canada shall be deemed not to be outstanding for the purpose of such computation. Such adjustment will be made successively whenever such a record date is fixed,
provided that if two or more such record dates or record dates referred to in paragraph 5.3(3) are fixed within a period of 25 Trading Days, such adjustment will be made successively as if each of such record dates occurred on the earliest of such
record dates. To the extent that such distribution is not so made or to the extent that any such rights, options or warrants so distributed are not exercised prior to the expiration thereof, the Exercise Price will then be readjusted to the Exercise
Price which would then be in effect if



- 21 -



---

such record date had not been fixed or to the Exercise Price which would then be in effect based upon such shares or
rights, options or warrants or evidences of indebtedness or cash, securities or other property or assets actually distributed or based upon the number or amount of securities or the property or assets actually issued or distributed upon the exercise
of such rights, options or Share Purchase Warrants, as the case may be.



|5.4 | Adjustment Rules
|--- | ----------------



|(1) | In any case in which this Article 5 shall require that an adjustment shall become effective immediately after a record date for or effective date of an event referred to herein,
SMTC Canada may defer, until the occurrence and consummation of such event, issuing to the holder of any Share Purchase Warrant exercised after such record date or effective date and before the occurrence and consummation of such event the
additional Exchangeable Shares or other securities or property issuable upon such exercise by reason of the adjustment required by such event, provided, however, that SMTC Canada will deliver to such holder, as soon as reasonably practicable after
such record date or effective dates, as applicable, an appropriate instrument evidencing such holders right to receive such additional Exchangeable Shares or other securities or property upon the occurrence and consummation of such event and
the right to receive any dividend or other distribution in respect of such additional Exchangeable Shares or other securities or property declared in favour of the holders of record of Exchangeable Shares or of such other securities or property on
or after the Exercise Date, or such later date as such holder would, but for the provisions of this Section 5.4, have become the holder of record of such additional Exchangeable Shares, warrants or of such other securities or property pursuant to
Subsection 4.2(1).
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | If SMTC Canada shall set a record date to determine the holders of the securities for the purpose of entitling them to receive any dividend or distribution or any subscription or
exercise rights and shall, thereafter and before the distribution to such securityholders of any such dividend, distribution or subscription or exercise rights, legally abandon its plan to pay or deliver such dividend, distribution or subscription
or exercise rights, then no adjustment in the number of Exchangeable Shares obtainable upon exercise of any Share Purchase Warrant shall be required by reason of the setting of such record date.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(3) | The adjustments provided for in this Article 5 are cumulative, shall, in the case of any adjustment to the Exchange Rate or the Exercise Price, be computed to the nearest one
one-hundredth of an Exchangeable Share and will apply (without duplication) to successive subdivisions, consolidations, distributions, issuances or other events resulting in any adjustment under the provisions of this Article 5, provided that,
notwithstanding any other provision of this Section 5.4, no adjustment of the Exchange Rate or the Exercise Price will be required (i) unless such adjustment would require an increase or decrease of at least 1% in the Exchange Rate or the Exercise
Price then in effect (provided, however, that any adjustment which by reason of this Subsection 5.4(3) is not required to be made will be carried forward and taken into account in any subsequent adjustment), or (ii) in respect of any Exchangeable
Shares issuable or issued pursuant to any option or share purchase plan of SMTC Canada or (iii) in respect of any Exchangeable Shares issuable or issued pursuant to the Special Warrants or upon exercise of the Share Purchase Warrants.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 22 -



---

|(4) | If any question arises with respect to the adjustments provided in this Article 5, such question shall be conclusively determined by SMTC Canadas auditors or, if they are
unable or unwilling to act, by such firm of chartered accountants as is appointed by SMTC Canada and acceptable to the Trustee. Such accountants shall have access to all necessary records of SMTC Canada and such determination shall be binding upon
SMTC Canada, the Trustee and the Warrantholders.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(5) | All shares of any class or other securities or property which a Warrantholder is at the time in question entitled to receive on the full exercise of his Share Purchase Warrants,
whether or not as a result of adjustments made pursuant to this Article 5 shall, for the purposes of the interpretation of this Indenture, be deemed to be Exchangeable Shares which such Warrantholder is entitled to subscribe for pursuant to the
exercise of such Share Purchase Warrants.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(6) | If and whenever at any time during the Adjustment Period, SMTC Canada shall take any action affecting or relating to the Exchangeable Shares, other than any action described in this
Article 5, which in the opinion of the directors, after consultation with the Trustee, would adversely affect the rights of any holders of Share Purchase Warrants, the Exchange Rate and/or the Exercise Price will be adjusted by the directors in such
manner, if any, and at such time, as the directors, may in their sole discretion determine to be equitable in the circumstances to such holders.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(7) | As a condition precedent to the taking of any action which would require an adjustment in any of the rights under the Share Purchase Warrants, SMTC Canada will take any action which
may, in the opinion of counsel to SMTC Canada, be necessary in order that SMTC Canada, or any successor to SMTC Canada or successor to the undertaking or assets of SMTC Canada, will be obligated to and may validly and legally issue all the
Exchangeable Shares or other securities or property which the holders of Share Purchase Warrants would be entitled to receive thereafter on the exercise thereof in accordance with the provisions hereof.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(8) | At least seven days before the earlier of the effective date of or record date for any event referred to in this Article 5 that requires or might require an adjustment in any of the

ARTICLE 10

CONCERNING THE TRUSTEE



|10.1 | Trust Indenture Legislation
|---- | ---------------------------



|(1) | If and to the extent that any provision of this Indenture limits, qualifies or conflicts with a mandatory requirement of Applicable Legislation, the mandatory requirement will
prevail.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | SMTC Canada and the Trustee each will at all times in relation to this Indenture and any action to be taken hereunder observe and comply with and be entitled to the benefits of
Applicable Legislation.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|10.2 | Trustees Authority to Carry on Business
|---- | ----------------------------------------



The Trustee represents and warrants to SMTC Canada that at the date hereof it is authorized to carry on the business of a trust company in Toronto,
Ontario. If, notwithstanding the provisions of this Section 10.2, it ceases to be authorized to carry on such business, the validity and enforceability of this Indenture and the Share Purchase Warrants issued hereunder shall not be affected in any
manner whatsoever by reason only of such event provided that the Trustee, within 30 days after ceasing to be authorized to carry on such business either becomes so authorized or resigns in the manner and with the effects specified in Section 10.8.



|10.3 | Rights and Duties of Trustee
|---- | ----------------------------



|(1) | In the exercise of the rights and duties prescribed or conferred by the terms of this Indenture, the Trustee will act honestly and in good faith with a view to the best interests of
the Warrantholders, and will exercise that degree of care, diligence and skill that a reasonably prudent warrant trustee would exercise in comparable circumstances. Subject to the foregoing, the Trustee shall not be bound to give any notice or do or
take any act, action or proceeding by virtue of the powers conferred on it hereby unless and until it shall have been required so to do under the terms hereof; nor shall the Trustee be required to take notice of any default hereunder, unless and
until notified in writing of such default, which notice shall distinctly specify the default desired to be brought to the attention of the Trustee and in the absence of any such notice the Trustee may for all purposes of this Indenture conclusively
assume that no default has been made in the observance or performance of any of the representations, warranties, covenants, agreements or conditions contained therein. Any such notice shall in no way limit any discretion herein given to the Trustee
to determine whether or not the Trustee shall take action with respect to any default.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | No provision of this Indenture will be construed to relieve the Trustee from liability for its own negligent act, negligent failure to act, wilful misconduct or bad faith.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(3) | The obligation of the Trustee to commence or continue any act, action or proceeding for the purpose of enforcing any right of the Trustee or the Warrantholders hereunder is on the
condition that, when required by notice to the Warrantholders by the Trustee, the Trustee is furnished by one or more Warrantholders with sufficient funds to commence or continue such act, action or proceeding and indemnity reasonably satisfactory
to the Trustee to protect and hold it harmless against the costs, charges and expenses and liabilities to be incurred thereby and any loss and damage it may suffer by reason thereof.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 35 -

|(4) | No provision of this Indenture will require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties or in the
exercise of any of its rights or powers unless it is so indemnified.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(5) | The Trustee may, before commencing or at any time during the continuance of any such act, action or proceeding, require the Warrantholders at whose instance it is acting to deposit
with the Trustee the Share Purchase Warrant Certificates held by them, for which certificates the Trustee will issue receipts.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(6) | Every provision of this Indenture that relieves the Trustee of liability or entitles it to rely on any evidence submitted to it is subject to the provisions of Applicable
Legislation, of this Section 10.2 and of Section 10.3.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|10.4 | Evidence, Experts and Advisers

|(1) | In addition to the reports, certificates, opinions and other evidence required by this Indenture, SMTC Canada will furnish to the Trustee such additional evidence of compliance with
any provision hereof, and in such form, as is prescribed by Applicable Legislation or as the Trustee reasonably requires by written notice to SMTC Canada.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | In the exercise of any right or duty hereunder the Trustee, if it is acting in good faith, may rely, as to the truth of any statement or the accuracy of any opinion expressed
therein, on any statutory declaration, opinion, report, certificate or other evidence furnished to the Trustee pursuant to a provision hereof or of Applicable Legislation or pursuant to a request of the Trustee, if such evidence complies with
Applicable Legislation and the Trustee examines such evidence and determines that it complies with the applicable requirements of this Indenture.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(3) | Whenever Applicable Legislation requires that evidence referred to in Subsection 10.3(1) be in the form of a statutory declaration, the Trustee may accept such statutory declaration
in lieu of a certificate of SMTC Canada required by any provision hereof.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(6) | Proof of the execution of any document or instrument in writing, including a Warrantholders Request, by a Warrantholder may be made by the certificate of a notary public, or
other officer with similar powers, that the person signing such instrument acknowledged to him the execution thereof, or by an affidavit of a witness to such execution, or in any other manner that the Trustee considers adequate.

discharging its duties hereunder and may pay reasonable remuneration for all services so performed by any of them, without taxation of costs of any counsel, and will not be responsible for any misconduct or negligence on the part of any of them who
has been selected with due care by the Trustee. Any remuneration so paid by the Trustee shall be repaid to the Trustee in accordance with Section 6.2.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(2) | Unless herein otherwise expressly provided, any money so held pending the application or withdrawal thereof under any provision of this Indenture shall be deposited in the name of
the Trustee in any Canadian chartered bank or trust company at the rate of interest (if any) then current on similar deposits or may be invested with the consent of the SMTC Canada in securities issued or guaranteed by the Government of Canada or a
province thereof or in obligations, maturing not more than one year from the date of the investment, of any Canadian chartered bank or trust company as SMTC Canada may consent to. All interest or other income received by the Trustee in respect of

| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (c) | subject to Section 10.9 the Trustee will not be bound to give notice to any person of the execution hereof;

costs and actions which may be brought against or suffered by it arising out of or connected with the performance by it of its duties hereunder except to the extent that such liabilities, suits, damages, costs and actions are attributable to the
negligence, wilful misconduct or bad faith of the Trustee. This provision shall survive the resignation or termination of the Trustee or the termination of this Indenture.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|10.9 | Replacement of Trustee
|---- | ----------------------



|(1) | The Trustee may resign its trust hereunder and be discharged from all further duties and liabilities hereunder, except as provided in this Section, by giving to SMTC Canada and the

|(7) | On any such appointment the new Trustee will be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Trustee without any
further assurance, conveyance, act or deed, but there will be immediately executed, at the expense of SMTC Canada, all such conveyances or other instruments as, in the opinion of counsel, are necessary or advisable for the purpose of assuring such
powers, rights, duties and responsibilities to the new Trustee provided that, any resignation or termination of the Trustee and appointment of a successor Trustee shall have executed an appropriate instrument accepting such appointment and, at the
request of SMTC Canada, the predecessor Trustee, upon payment of its outstanding remuneration and expenses, shall execute and deliver to the successor Trustee an appropriate instrument transferring to such successor Trustee all rights and powers of
the Trustee hereunder.

fiduciary hereunder and its role in any other capacity and if a material conflict of interest arises hereafter it will, within 90 days after ascertaining that it has such material conflict of interest, either eliminate the conflict of interest or

If any such material conflict of
interest exists or hereafter shall exist, the validity and enforceability of this Indenture and of the Share Purchase Warrants shall not be affected in any manner whatsoever by reason thereof.

Exercisable to Acquire

Exchangeable Shares

of

SMTC MANUFACTURING CORPORATION OF CANADA



(Incorporated under the Business Corporations Act (Ontario))



THIS IS TO CERTIFY THAT, for value received,
 (the holder) is the registered holder of the number of Share Purchase Warrants (Share Purchase Warrants)
of SMTC Manufacturing Corporation of Canada (SMTC Canada) specified above and for each Share Purchase Warrant held is thereby entitled, to be issued fully paid and non-assessable exchangeable shares (Exchangeable
Shares) in the capital of SMTC Canada, on the basis of one Exchangeable Share for each such Share Purchase Warrant, subject to the limitation referred to below, by surrendering to CIBC Mellon Trust Company (the Trustee)
at its principal transfer office in Toronto, Ontario during the exercise period hereinafter referred to, a certified cheque or bank draft made payable to SMTC Canada in the amount of the Exercise Price as hereinafter determined in respect of each
Exchangeable Share to be issued, this Share Purchase Warrant Certificate and a notice of exercise in the form set forth in Appendix 1 annexed hereto duly completed and executed provided notice is also sent to SMTC Canada by delivering to it a copy
of such documents.



Capitalized terms which are not otherwise defined herein
shall have the same meaning as in the share purchase warrant indenture (which indenture, together with all instruments supplemental or ancillary thereto, is herein referred to as the Share Purchase Warrant Indenture) dated as of
March 3, 2004 between SMTC Canada and the Trustee, as trustee.



Surrender of
this Share Purchase Warrant Certificate will be deemed to have been effected only on personal delivery thereof to, or, if sent by mail or other means of transmission, on actual receipt thereof by, the Trustee at the office specified above.



This Share Purchase Warrant Certificate evidences Share Purchase Warrants of
SMTC Canada issued or issuable under the provisions of the Share Purchase Warrant Indenture. Reference is made to the Share Purchase Warrant Indenture for particulars of the rights of the holders of the Share Purchase Warrants and of SMTC Canada and
of the Trustee in respect thereof and of the terms and conditions upon which the Share Purchase Warrants are issued and held, all to the same effect as if the provisions of the Share Purchase Warrant Indenture were herein set forth, to all of which
the holder, by acceptance hereof, assents. To the extent of any inconsistency between the terms of the Share Purchase Warrant Indenture and the terms of this Share Purchase Warrant Certificate, the terms of the Share Purchase Warrant Indenture shall
prevail. SMTC Canada will furnish to the holder, on request and upon payment of a reasonable charge for photocopying and postage, a copy of the Share Purchase Warrant Indenture.

The Share Purchase Warrants evidenced by this Share Purchase Warrant Certificate may be exercised by the holder until
5:00 p.m. (Toronto time) on March 3, 2009.



On and after the date of any
exercise of the Share Purchase Warrants evidenced by this Share Purchase Warrant Certificate, the holder will have no rights hereunder except to receive certificates representing the Exchangeable Shares thereby issued to him upon delivery of a
certified cheque or bank draft payable to SMTC Canada in the amount of $1.85 (the Exercise Price) in respect of each Exchangeable Share to be issued, this Share Purchase Warrant Certificate and duly completed Notice of Exercise as
set out on Appendix 1 to the Trustee at its principal office in Toronto, Ontario. After the Expiry Time, all rights under any unexercised Share Purchase Warrant evidenced hereby will wholly cease and terminate and this Share Purchase
Warrant Certificate will be void.



SMTC Canada will not be obligated to issue
any fraction of an Exchangeable Share on the exercise of any Share Purchase Warrant. To the extent that a holder of Share Purchase Warrants would otherwise have been entitled to receive, on the exercise of the Share Purchase Warrants, a fraction of
an Exchangeable Share such rate may only be exercised in respect of such fraction in connection with another Share Purchase Warrant or Share Purchase Warrants which in the aggregate entitle the holder to receive a whole number of Exchangeable
Shares. If a Warrantholder is not able to combine Share Purchase Warrants so as to be entitled to acquire a whole number of Exchangeable Shares the number of Exchangeable Shares which such Warrantholder is entitled to receive shall be rounded up to
the nearest whole number.



The Share Purchase Warrant Indenture provides for
adjustments to the number of Exchangeable Shares issuable upon the exercise of the Share Purchase Warrants and the Exercise Price in certain events set forth therein.



No Exchangeable Share will be issued pursuant to any Share Purchase Warrant if the issuance of such security would constitute a violation of
the securities laws of any applicable jurisdiction or require SMTC Canada to qualify or register such Exchangeable Shares in any jurisdiction other than the Qualifying Jurisdictions.



The Share Purchase Warrant Indenture contains provisions making binding on all holders of Share Purchase Warrants outstanding thereunder
resolutions passed at meetings of such holders held in accordance with such provisions and instruments in writing signed by holders of a specified majority of all outstanding Share Purchase Warrants.



On presentation at the principal office of the Trustee in Toronto, Ontario, subject to the
provisions of the Share Purchase Warrant Indenture and on compliance with the reasonable requirements of the Trustee, one or more Share Purchase Warrant Certificates may be exchanged for one or more Share Purchase Warrant Certificates of different
denominations evidencing in the aggregate the same number of Share Purchase Warrants as the Share Purchase Warrant Certificate or Share Purchase Warrant Certificates being exchanged.



The Share Purchase Warrants evidenced by this Share Purchase Warrant Certificate may only be transferred, upon compliance with the
conditions prescribed in the Share Purchase Warrant Indenture, on the register of transfers to be kept at the principal office of the Trustee in Toronto, Ontario by the holder or his executors, administrators or other legal representatives or his or
their attorney duly appointed by an instrument in writing in form and execution satisfactory to the

Trustee, and, upon compliance with such requirements and such other reasonable requirements as the Trustee may prescribe,
such transfer will be duly notified on such register of transfers by the Trustee. Notwithstanding the foregoing, SMTC Canada will be entitled, and may direct the Trustee, to refuse to record any transfer of any Share Purchase Warrant on such
register if such transfer would constitute a violation of the securities laws of any jurisdiction or require SMTC Canada to qualify the Exchangeable Shares for distribution in any jurisdiction other than the Qualifying Jurisdictions.



The holding of this Share Purchase Warrant Certificate will not constitute the holder a
shareholder of SMTC Canada or entitle him to any right or interest in respect thereof except as otherwise provided in the Share Purchase Warrant Indenture.



This Share Purchase Warrant Certificate will not be valid for any purpose until it has been certified by or on behalf of the Trustee for the time being under the Share
Purchase Warrant Indenture. Time will be of the essence hereof.



In the event
that SMTC Canada is unable to obtain a receipt for the Final Prospectus in a Qualifying Jurisdiction, the Share Purchase Warrants and the Exchangeable Shares issuable upon the exercise of the Share Purchase Warrants will be subject to statutory
resale restrictions under the applicable securities legislation of that province. In addition, statutory restrictions will apply to the resale of such Share Purchase Warrants and such Exchangeable Shares that are acquired prior to the issuance of
receipts for the Final Prospectus by the securities regulatory authority in the applicable Qualifying Jurisdiction. Holders are advised to consult their own legal advisors in this regard.
