transactions are contingent upon the release of the Escrowed Funds. For the purpose of satisfying clauses (i) and (ii) of this Section 3.3(1), the Trustee may act and rely on a certificate to such effect delivered to it by SMTC Canada, and for the
purpose of satisfying clause (iii) of this Section 3.3(1), the Trustee may rely on a certificate of the Lead Underwriter to such effect.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | If the evidence contemplated by Subsection 3.3(1) is not delivered to the Trustee on or before the Prospectus Qualification Deadline then the Trustee will, within two
business days of the Prospectus Qualification Deadline, send to each Special Warrantholder a written notice as to the non-receipt of such evidence. Upon receipt of such notice, each Special Warrantholder will be entitled, at any time thereafter up
to the Expiry Time, to instruct the Trustee in writing (a Release Notice) to release to such Special Warrantholder its pro rata share of the Escrowed Funds, together with interest thereon, if any, based upon its holdings of
Special Warrants. Contemporaneously with the release of any Escrowed Funds as aforesaid (i) all Special Warrants held by a Special Warrantholder that has delivered a Release Notice to the Trustee shall be cancelled and, except as specifically set
forth in the Underwriting Agreement or in clause (ii) of this Section 3.3(2), such Special Warrantholder shall have no further rights in respect thereof, other than the right to receive their pro rata share of the Escrowed Funds and interest, if
any, thereon, and (ii) SMTC Canada shall pay to such Special Warrantholder, in immediately available funds, pro rata to their holdings of Special Warrants an amount equal to the difference between the aggregate purchase price of the Special Warrants
and the Escrowed Funds.

Special Warrant Certificate or otherwise in form satisfactory to the Trustee executed by, the registered 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 a written acknowledgement by the transferee substantially in the form of Appendix 3 to the Special Warrant Certificate or otherwise in form satisfactory to the Trustee executed by the transferee
and, subject to compliance with Sections 2.7, 2.8 and 2.9 and such requirements and such other reasonable requirements as the Trustee may prescribe, such transfer will be duly noted on one of such registers of transfers by the Trustee within two
business days of the satisfaction of all such requirements.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(5) | SMTC Canada will be entitled, and may direct the Trustee in writing, to refuse to recognize any transfer, or enter the name of any transferee, of any Special Warrant on the
registers referred to in Subsection 4.1(2), or on any branch registers maintained pursuant to Subsection 4.1(8), if such transfer would constitute a violation of the securities laws of any jurisdiction or would require SMTC Canada to qualify the
Exchangeable Shares or Share Purchase Warrants issuable on exercise or deemed exercise of the Special Warrants for distribution in any jurisdiction other than the Qualifying Jurisdictions.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(6) | Neither SMTC Canada nor the Trustee will be bound to take notice of or see to the execution of any trust, whether express, implied or constructive, in respect of any Special
Warrant, and may transfer any Special Warrant on the written direction of the person registered as the holder thereof and delivered in accordance with Subsection 4.1(3), whether named as trustee or otherwise, as though that person were the
beneficial owner thereof.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(7) | The registers referred to in Subsection 4.1(2), and any branch registers maintained pursuant to Subsection 4.1(8), will at all reasonable times be open for inspection by SMTC Canada
and any Special Warrantholder. The Trustee will from time to time when requested so to do in writing by SMTC Canada or any Special Warrantholder (upon payment of the Trustees reasonable charges), furnish SMTC Canada or such Special
Warrantholder with a list of the names and addresses of holders of Special Warrants entered on such registers and showing the number of Special Warrants held by each such holder.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(8) | The Trustee, with the approval of SMTC Canada, may at any time and from time to time change the place at which the registers referred to in Subsection 4.1(2) are kept, cause branch
registers of holders or transfers to be kept at other places and close such branch registers or change the place at which such branch registers are kept. Notice of any such change or closure shall be given by the Trustee to SMTC Canada and the
holders of Special Warrants.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(9) | The Trustee shall retain until the sixth anniversary of the Expiry Time all instruments of transfer of Special Warrants which are tendered for registration including the details

of different denomination evidencing in the aggregate the same number of Special Warrants as the Special Warrant Certificate or Special Warrant Certificates being exchanged, and such holder shall pay the reasonable cost thereof.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 17 -



---

|(2) | Special Warrant Certificates may be exchanged only at the principal office in Toronto, Ontario of the Trustee or at any other place designated by SMTC Canada with the approval of
the Trustee.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(3) | Any Special Warrant Certificate tendered for exchange shall be surrendered to the Trustee or its agent and cancelled.
|--- | ---------------------------------------------------------------------------------------------------------------------



|(4) | SMTC Canada will sign all Special Warrant Certificates necessary to carry out exchanges pursuant to this Section 4.2 and the Trustee shall certify such Special Warrant Certificates.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.3 | No Charges for Transfer or Exchange
|--- | -----------------------------------



No charge, including any stamp tax or other governmental levy, will be levied on a presenter of a Special Warrant Certificate pursuant to this Indenture
for the transfer of any Special Warrant or the exchange of any Special Warrant Certificate.



|4.4 | Ownership of Special Warrants
|--- | -----------------------------



|(1) | SMTC Canada and the Trustee may deem and treat the person in whose name any Special Warrant is registered as the absolute owner of such Special Warrant for all purposes, and such
person will for all purposes of this Indenture be and be deemed to be the absolute owner thereof, and SMTC Canada and the Trustee will not be affected by any notice or knowledge to the contrary except as required by statute or by order of a court of
competent jurisdiction.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | The registered holder of any Special Warrant will be entitled to the rights evidenced thereby free from all equities and rights of set-off or counterclaim between SMTC Canada and
the original or any intermediate holder thereof and all persons may act accordingly, and the delivery to any such registered holder of the Exchangeable Shares and Share Purchase Warrants issued on exercise or deemed exercise of such Special Warrant
will be a good discharge to SMTC Canada and the Trustee therefor and, unless SMTC Canada or the Trustee are required by statute or by an order of a court of competent jurisdiction, neither SMTC Canada nor the Trustee will be bound to inquire into
the title of any such registered holder.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.5 | Assumption by Transferee
|--- | ------------------------



Upon becoming a Special 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 Special Warrant, the transferor thereof shall cease to have any further rights under this Indenture with respect to such Special Warrant
or the Exchangeable Shares and Share Purchase Warrants to be issued on exercise or deemed exercise thereof.

ARTICLE 5

EXERCISE OF SPECIAL WARRANTS



|5.1 | Exercise
|--- | --------



|(1) | Subject to the limitation set forth in Subsection 5.1(2) and Section 5.6, holders of Special Warrants may at any time following the release of the Escrowed Funds pursuant to Section
3.3(1) and prior to the Expiry Time exercise the right thereby conferred to be issued Units, by surrendering to the Trustee at the principal office in Toronto, Ontario of the Trustee, 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, the Special Warrant Certificate evidencing such Special Warrants, with a duly completed and executed notice of exercise substantially in the form
set out in Appendix 1 to such Special Warrant Certificate, provided such notice is also given to SMTC Canada by either the Special Warrantholder or the Trustee by delivering to SMTC Canada a copy of such documents. Notwithstanding the foregoing, a
holder may exercise the Special Warrants by delivering to the Trustee a facsimile transmission of the Special Warrant Certificate(s) evidencing such Special Warrants together with a duly completed and executed notice of exercise in the form set out
in Appendix 1 to such Special Warrant Certificate(s) to the Trustee provided that the original Special 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 Special Warrant Certificate with a duly completed and executed notice of exercise referred to in Subsection 5.1(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 receipt thereof by, the Trustee or one of the other persons at the office or one of the other places specified in Subsection 5.1(1) provided however that if exercise
is made by facsimile transmission as set out in Subsection 5.1(1), the Special Warrant Certificate and executed notice of exercise will be deemed to be surrendered as at the date of the facsimile transmission only in the event the original Special
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 5.1(1) must be signed by the Special Warrantholder, 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, acting reasonably, and, if any Exchangeable Shares and Share Purchase Warrants thereby issuable are to be issued to a person or persons other than
the Special Warrantholder then the notice of exercise must specify the name or names and the address or addresses of each such person or persons and the number of Exchangeable Shares and Share Purchase Warrants to be issued to each such person if
more than one is so specified.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



- 19 -



---

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



|5.2 | Deemed Exercise
|--- | ---------------



|(1) | If any Special Warrant has not been exercised pursuant to Section 5.1, such Special Warrant will be deemed to have been exercised by the Trustee on behalf of the holders (without
any further action on the part of such holder) immediately prior to the Expiry Time. SMTC Canada will as soon as practicable and in all events no later than two business days after the Deemed Exercise Date give notice of the Deemed Exercise Date to
the Trustee and cause the Trustee as soon as practicable and in all events no later than five business days after the Deemed Exercise Date to give notice to the holders of Special Warrants. Such notice shall specify that the Special Warrants are
deemed to have been exercised automatically in accordance with their terms and will further specify that such holders will receive the certificates representing the Exchangeable Shares and the certificates representing the Share Purchase Warrants to
which the holder is entitled (without further action on the part of the holder or SMTC Canada) within five business days of such notice.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | The holder of any Special Warrant deemed to have been exercised pursuant to Subsection 5.2(1) will have no rights thereunder except (i) to receive certificates representing the
Exchangeable Shares and certificates representing Share Purchase Warrants thereby issued to him, and (ii) as specifically set forth in the Underwriting Agreement..
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5.3 | Effect of Exercise or Deemed Exercise
|--- | -------------------------------------



|(1) | Upon the exercise of any Special Warrant in accordance with Section 5.1 or upon the deemed exercise of any Special Warrant in accordance with Section 5.2, the Exchangeable Shares
and the Share Purchase Warrants thereby issuable will be deemed to have been issued, and the person or persons to whom such Exchangeable Shares and Share Purchase Warrants are to be issued will be deemed to have become the holder or holders of
record thereof, on the Exercise Date or the Deemed Exercise Date, as the case may be, unless the registers for the Exchangeable Shares and Share Purchase Warrants are closed on that date, in which case such Exchangeable Shares and Share Purchase
Warrants 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 registers are reopened, but such Exchangeable Shares and Share Purchase Warrants
will be issued on the basis of the number of Exchangeable Shares and Share Purchase Warrants to which such person or persons were entitled on the Exercise Date or the Deemed Exercise Date, as the case may be.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 20 -



---

|(2) | As soon as practicable and in any event not later than, in the case of the exercise of any Special Warrant in accordance with Section 5.1, the fifth business day on which the
registers for the Exchangeable Shares and Share Purchase Warrants have been open after such exercise or, in the case of the deemed exercise of any Special Warrant in accordance with Section 5.2, within five business days after the surrender to the
Trustee of the Special Warrant Certificate evidencing such Special Warrant in accordance with Subsection 5.2(2), SMTC Canada will cause the Trustee to mail to the person or persons in whose name or names the Exchangeable Shares and Share Purchase
Warrants thereby issued have been issued, at his or their respective addresses.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(3) | If any Exchangeable Shares or Share Purchase Warrants issuable pursuant to any Special Warrant are to be issued to a person or persons other than the Special Warrantholder, the
Special 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 and Share Purchase Warrants unless or until such amount has been so paid or the Special 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.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5.4 | No Fractional Exchangeable Shares or Share Purchase Warrants
|--- | ------------------------------------------------------------



SMTC Canada will not, whether pursuant to an adjustment in accordance with Section 5.7 or under any other circumstances, be obligated to issue any
fraction of a Exchangeable Share or a Share Purchase Warrant on the exercise or deemed exercise of Special Warrants. To the extent that a holder of Special Warrants would otherwise have been entitled to receive, on the exercise or deemed exercise of
Special Warrants, a fraction of a Exchangeable Share or a Share Purchase Warrant, such right may only be exercised in respect of such fraction in connection with another Special Warrant or Special Warrants which in the aggregate entitle the holder
to receive a whole number of Exchangeable Shares or Share Purchase Warrants. If a Special Warrantholder is not able to combine Special Warrants so as to be entitled to acquire a whole number of Exchangeable Shares or Share Purchase Warrants, the
number of Exchangeable Shares or Share Purchase Warrants which such Special Warrantholder is entitled to receive shall be rounded up to the nearest whole number.



|5.5 | Recording
|--- | ---------



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



|5.6 | Restrictions
|--- | ------------



No Exchangeable Shares and no Share Purchase Warrants will be issued on exercise or deemed exercise of any Special Warrant, if in the written opinion of
counsel to SMTC Canada (delivered to the Trustee prior to issue), the issuance of such Exchangeable Shares or Share Purchase Warrants would constitute a violation of the securities laws of any applicable



- 21 -



---

jurisdiction or require SMTC Canada to qualify the Exchangeable Shares and Share Purchase Warrants issuable on exercise
or deemed exercise of the Special Warrants for distribution in any jurisdiction other than the Qualifying Jurisdictions. Without limiting the generality of the preceding sentence, if any Special Warrant is exercised before the Prospectus
Qualification Date or the Registration Qualification Date, the certificates representing the Exchangeable Shares and Share Purchase Warrants 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 other 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 as applicable, 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.



|5.7 | Adjustments
|--- | -----------



|(1) | The rights of the holder of any Special Warrant, including the number of Exchangeable Shares issuable upon the exercise or deemed exercise of such Special Warrant, will be adjusted
from time to time in the events and in the manner provided in, and in accordance with the provisions of this Section 5.7, and for such purposes and as used in this Section 5.7:
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (a) | Adjustment Period means the period commencing on the Closing Date and ending at the Expiry Time; and
| | --- | ------------------------------------------------------------------------------------------------------



| | (b) | Exchange Rate means the rate at which Exchangeable Shares are issuable upon the exercise or deemed exercise of any Special Warrant, which rate, subject to
adjustment in accordance with this Indenture, is one Exchangeable Share and one half of one Share Purchase Warrant for each Special Warrant as of the Closing Date.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | The Exchange Rate 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 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
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 22 -



---

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 5.7(2). To the extent that this Subsection 5.7(2) has become operative because of an issue of
convertible securities referred to in clause (iii) above, the number of Exchangeable Shares obtainable under each Special Warrant shall be readjusted based on the number of Exchangeable Shares issuable upon conversion or exchange of such convertible
or exchangeable securities.



|(3) | 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 5.7(2)), (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 Special Warrants which are thereafter exercised or deemed to have been exercised
will be entitled to receive, and shall accept, in lieu of the number of Exchangeable Shares and Share Purchase Warrants to which such holder was theretofore entitled (after giving effect to all adjustments under this Section 5.7 required as of such
date) upon such exercise or deemed 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 immediately before the transaction such holder was theretofore entitled upon exercise of the Special Warrants. If necessary as a result of any such event, appropriate
adjustments will be made in the application of the provisions set forth in this Section 5.7 with respect to the rights and interests thereafter of the holders of Special Warrants to the end that the provisions set forth in this Section 5.7 and in
this Indenture will thereafter correspondingly be made applicable, as nearly as may reasonably be possible, in relation to any shares or other securities or property thereafter deliverable upon the exercise or deemed exercise of any Special 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. No such capital reorganization or event as described
in this Section 5.7(3) shall be carried into effect unless all necessary steps to be taken by SMTC Canada shall have been taken to afford the Special Warrantholders the entitlement to receive the number of securities or property of SMTC Canada or of
SMTC Canadas successor or transferee, as the case may be, contemplated hereby, in the same manner as holders of Exchangeable Shares, subject to adjustment thereafter in accordance with provisions the same, as nearly possible, as those
contained in this Section 5.7.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(4) | If and whenever at any time during the Adjustment Period SMTC Canada proposes to issue or distribute securities of SMTC Canada (including rights, options or warrants to purchase
shares of SMTC Canada or securities convertible into or exchangeable for shares of SMTC Canada or property or assets, including cash or evidences of indebtedness (but specifically excluding dividends payable in cash)) to all or substantially all of
the holders of the Exchangeable Shares, except in respect of any Exchangeable Shares issuable pursuant to any option, warrant, share option plan and/or share purchase plan in force from time to time for directors, officers, employees or consultants
of SMTC Canada and its affiliates or as otherwise specified in the Underwriting Agreement, such securities, property or assets shall also be offered to the Special Warrantholders, and the Special Warrantholders shall be entitled to receive, and
shall receive for the same aggregate consideration payable, if any, in addition to the number of Exchangeable Shares to which the Special Warrantholder was therefore entitled upon such exercise, the kind and amount of shares or other securities or
property which result from such issue or distribution as if, on the effective date or the record date, as the case may be, at which holders of Exchangeable Shares are determined for the purpose thereof, such Special Warrantholder had been the
registered holder of the number of Exchangeable Shares to which the Special Warrantholder 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 Section 5.7 with respect to the rights and interests thereafter of the holders of Special Warrants to the end that the provisions set forth in this Section 5.7 and in this Indenture will thereafter correspondingly be
made applicable, as nearly as may reasonably be, in relation to any shares or other securities or property thereafter deliverable upon the exercise or deemed exercise of any Special 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) | In any case in which this Section 5.7 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 Special Warrant exercised or deemed to have been 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 or deemed 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 date, 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 the Deemed Exercise Date, as the case may be, or such later date as such holder would, but for the provisions of this Subsection 5.7(5), have become the holder of record of such
additional Exchangeable Shares or of such other securities or property pursuant to Subsection 5.3(1).

|(6) | If SMTC Canada shall set a record date to determine the holders of 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 Special Warrant shall be required by reason of the setting of such record date.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(7) | The adjustments provided for in this Section 5.7 are cumulative, shall, in the case of any adjustment to the Exchange Rate, be computed to the nearest one one-hundredth of a
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 Section 5.7, provided that, notwithstanding any
other provision of this Section 5.7, no adjustment of the Exchange Rate will be required (i) unless such adjustment would require an increase or decrease of at least 1% in the Exchange Rate then in effect (provided, however, that any adjustment
which by reason of this Subsection 5.7(7) is not required to be made will be carried forward and taken into account in any subsequent adjustment), (ii) in respect of any Exchangeable Shares issuable or issued pursuant to any option, warrant, share
option plan, share purchase plan of SMTC Canada or as otherwise specified in the Underwriting Agreement, or (iii) in respect of any Exchangeable Shares issuable or issued pursuant to the Special Warrants.

|(8) | If any question arises with respect to the adjustments provided in this Section 5.7, 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 Special Warrantholders.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(9) | All shares of any class of securities or property which a Special Warrantholder is at the time in question entitled to receive on the full exercise of such holders Special
Warrants, whether or not as a result of adjustments made pursuant to this Section 5.7 shall, for the purposes of the interpretation of this Indenture, be deemed to be securities which such Special Warrantholder is entitled to acquire pursuant to
such Special Warrants.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(10) | 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
Section 5.7, which in the opinion of the directors of SMTC Canada would adversely affect the rights of any holders of Special Warrants, the Exchange Rate will be adjusted by the directors in such manner, if any, and at such time, as the directors
may in their sole discretion, subject to the approval of any stock exchange on which the Exchangeable Shares are listed and posted for trading, determine to be equitable in the circumstances to such holders.
|---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(11) | As a condition precedent to the taking of any action which would require an adjustment in any of the rights under the Special 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 Special Warrants would be entitled to receive thereafter on the exercise or deemed exercise thereof in accordance with the provisions hereof.



|(12) | At least seven days before the earlier of the effective date of or record date for any event referred to in this Section 5.7 that requires or might require an adjustment in any of
the rights under the Special Warrants or such longer notice period as may be applicable in respect of notices required to be delivered by SMTC Canada to holders of its Exchangeable Shares, SMTC Canada will:
|---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

calculated.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Such notice need only set forth such particulars as
have been determined at the date such notice is given. If any adjustment for which such notice is given is not then determinable, promptly after such adjustment is determinable SMTC Canada will:



| | (c) | file with the Trustee a certificate of SMTC Canada showing the computation of such adjustment; and
| | --- | --------------------------------------------------------------------------------------------------



| | (d) | give notice to the Special Warrantholders of such adjustment.
| | --- | -------------------------------------------------------------



Where a notice pursuant to this Subsection has been given, the Trustee shall be entitled to act and rely on any adjustment calculation of SMTC Canada or SMTC
Canadas auditors.



|(13) | Subject to Subsection 11.2(1), the Trustee shall not:
|---- | -----------------------------------------------------



| | (a) | at any time be under any duty or responsibility to any Special Warrantholder to determine whether any facts exist which may require any adjustment in the Exchange Rate, or with
respect to the nature or extent of any such adjustment when made, or with respect to the method employed in making same;

| | (b) | be accountable with respect to the validity or value (or the kind or amount) of any Exchangeable Shares or of any shares or other securities or property which may at any time be
issued or delivered upon the exercise or deemed exercise of any Special Warrant; or

| | (c) | be responsible for any failure of SMTC Canada to make any cash payment or to issue, transfer or deliver Exchangeable Shares or certificates representing Exchangeable Shares upon the
surrender of any Special Warrant for the purpose of exercise or deemed exercise, or to comply with any of the covenants contained in this Section 5.7.

SPECIAL WARRANTS

Exercisable to Acquire

Exchangeable Shares and Share Purchase Warrants

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 Special Warrants of SMTC Manufacturing Corporation of Canada (SMTC Canada) specified above and, for each Special Warrant held, is thereby entitled, without payment of any
additional consideration, to be issued one Unit consisting of one fully paid and non-assessable exchangeable share (Exchangeable Share) in the capital of SMTC Canada and one half of one Exchangeable Share Purchase Warrant (each whole
warrant a Share Purchase Warrant), by surrendering to CIBC Mellon Trust Company (the Trustee) at its principal transfer office in Toronto, Ontario during the exercise period hereinafter referred to, this Special Warrant
Certificate, with a notice of exercise in the form set forth in Appendix 1 annexed hereto duly completed and executed.



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



Surrender of this Special 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 Special Warrant Certificate evidences Special Warrants of SMTC Canada issued or issuable under the provisions of the Special Warrant Indenture. Reference is made to the Special Warrant Indenture for particulars
of the rights of the holders of the Special Warrants and of SMTC Canada and of the Trustee in respect thereof and of the terms and conditions upon which the Special Warrants are issued and held, all to the same effect as if the provisions of the
Special 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 Special Warrant Indenture and the terms of this Special Warrant Certificate, the
terms of the Special Warrant Indenture shall prevail. SMTC Canada will furnish to the holder, on request and without charge a copy of the Special Warrant Indenture.



The Special Warrants evidenced by this Special Warrant Certificate may be exercised by the holder in certain circumstances until 5:00 p.m.
(Toronto time) (the Expiry Time) on the date that is the earlier of (i) the 6thbusiness day following
the Prospectus Qualification Date and (ii) March 3, 2005, provided that if such Special Warrants have not been exercised by the Expiry Time, such Special Warrants will be deemed to have been exercised by the holder (without any



- 2 -



---

further action on the part of the holder) immediately prior to the Expiry Time. Provided the Escrowed Funds have been
released, SMTC Canada will as soon as practicable and in all events, no later than two business days after the Prospectus Qualification Date, give notice of the Prospectus Qualification Date and copies of the Final Prospectus to the Trustee and
cause the Trustee as soon as practicable and in all events no later than five business days after the Prospectus Qualification Date to give notice of the Prospectus Qualification Date to the holders of Special Warrants, together with a copy of the
Final Prospectus. Such notice shall specify that the Special Warrants are deemed to have been exercised automatically in accordance with their terms and will further specify that such holders will receive the certificates representing the
Exchangeable Shares and the certificates representing the Share Purchase Warrants to which the holder is entitled (without further action on the part of the holder or SMTC Canada) within five business days of such notice. Subject to the limitation
referred to below, and where there has not been a deemed exercise by the holder, the holder may exercise less than all of the Special Warrants evidenced by this Special Warrant Certificate, in such event the holder shall be entitled to receive,
without charge therefore a new Special Warrant Certificate evidencing the balance of the Special Warrants not exercised.



On and after the date of any exercise or deemed exercise of the Special Warrants evidenced by this Special Warrant Certificate, the holder will have no rights hereunder
except to receive certificates representing the Exchangeable Shares and certificates representing Share Purchase Warrants thereby issued to it upon surrender of this Special Warrant Certificate to the Trustee at its principal office in Toronto,
Ontario, or upon deemed exercise of the Special Warrants or as otherwise provided in the Special Warrant Indenture.



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



The Special Warrant
Indenture provides for adjustments to the number of Exchangeable Shares issuable upon the exercise or deemed exercise of the Special Warrant, and the Exercise Price in certain events set forth therein.



The Special Warrant Indenture contains provisions making binding on all holders of Special
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 Special Warrants.



On presentation at the principal office of the Trustee in Toronto, Ontario, subject to the
provisions of the Special Warrant Indenture and on compliance with the reasonable requirements of the Trustee, one or more Special Warrant Certificates may be exchanged for one or more



- 3 -



---

Special Warrant Certificates of different denominations evidencing in the aggregate the same number of Special Warrants
as the Special Warrant Certificate or Special Warrant Certificates being exchanged.



The Special Warrants evidenced by this Special Warrant Certificate may only be transferred, upon compliance with the conditions prescribed in the Special 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 recorded 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 Special 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, Share Purchase
Warrants or Underlying Common Shares for distribution in any jurisdiction other than the Qualifying Jurisdictions.



The holding of this Special 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 Special Warrant Indenture. The Share Purchase Warrants will be issued and created pursuant to, and will be governed by, a share purchase warrant indenture dated March 3, 2004 between SMTC Canada and the Trustee.



This Special 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 Special Warrant Indenture. Time will be of the essence hereof.



SMTC Canada has covenanted under the Special Warrant Indenture that SMTC Canada will prepare in conformity with the requirements of all Applicable Legislation in all
material respects, and file the Preliminary Prospectus with the Securities Commissions as soon as possible, and shall use its commercially reasonable efforts to obtain receipts therefor from the Securities Commissions as soon as commercially
practicable thereafter. SMTC Canada will use its commercially reasonable efforts to resolve as soon as commercially practicable any regulatory deficiencies in respect of the Preliminary Prospectus. As soon as possible after such deficiencies have
been resolved and/or satisfied, SMTC Canada will prepare and file in conformity with the requirements of Applicable Legislation, in all material respects, the Final Prospectus with the Securities Commissions. SMTC Canada will use its commercially
reasonable efforts to obtain receipts therefor from the Securities Commissions as soon as commercially practicable, but in no event later than the Prospectus Qualification Deadline, qualifying the distribution of the Units, comprised of Exchangeable
Shares and Share Purchase Warrants, issuable on the exercise of the Special Warrants in each of the Qualifying Jurisdictions. SMTC Canada will prepare in conformity with the requirements of all Applicable Legislation in all material respects, and
file the Registration Statement with the United States Securities and Exchange Commission, registering the distribution of the Underlying Common Shares issuable on the exchange of Exchangeable Shares, by the holder thereof.



If the Prospectus Qualification Date does not occur on or before the Prospectus Qualification
Deadline or if the Registration Qualification Date does not occur on or before the Registration



- 4 -



---

Qualification Deadline, each Special Warrant exercised after the Prospectus Qualification Deadline will entitle the
holder thereof to receive 1.1 Units without the payment of additional consideration.



Statutory restrictions will apply to the resale of Units, comprised of Exchangeable Shares and Share Purchase Warrants that are acquired prior to the Prospectus Qualification Date. In the event that SMTC Canada is unable to cause the
Registration Statement to be filed with, and declared effective by, the United States Securities and Exchange Commission, the Underlying Common Shares will be subject to statutory hold periods during which they may not be resold in Canada or the
United States subject to certain limited exceptions. Holders are advised to consult their own legal advisors in this regard.

|TO: |  | The Registrar and Transfer Agent for securities
of SMTC Manufacturing Corporation of Canada



The undersigned (a) acknowledges that
the sale of the securities of SMTC Manufacturing Corporation of Canada (the Company) to which this declaration relates is being made in reliance on Rule 904 of Regulation S under the United States Securities Act of 1933, as amended (the
1933 Act), and (b) certifies that (1) the undersigned is not an affiliate of the Company as that term is defined in the 1933 Act, (2) the offer of such securities was not made to a person in the United States and either (A) at the time
the buy order was originated, the buyer was outside the United States, or the seller and any person acting on its behalf reasonably believed that the buyer was outside the United States and obtained written certification from the buyer that it was
outside of the United States, or (B) the transaction was executed in, on or through the facilities of the Toronto Stock Exchange or any other designated offshore securities market as defined in Regulation S under the 1933 Act and neither the seller
nor any person acting on its behalf knows that the transaction has been prearranged with a buyer in the United States, (3) neither the seller nor any affiliate of the seller nor any person acting on any of their behalf has engaged or will engage in
any directed selling efforts in the United States in connection with the offer and sale of such securities, (4) the sale is bona fide and not for the purpose of washing off the resale restrictions imposed because the securities are
restricted securities (as such term is defined in Rule 144(a)(3) under the 1933 Act), (5) the seller does not intend to replace the securities sold in reliance on Regulation S of the 1933 Act with fungible unrestricted securities, (6)
the contemplate sale is not a transaction, or part of a series of transaction which, although in technical compliance with Regulation S, is part of a plan or scheme to evade the registration provisions of the 1933 Act, and (7) the seller is not a
dealer or a person receiving selling concessions. Terms used herein have the meanings given to them by Regulation S.
