Dear
Sirs/Mesdames:



The undersigned, Orion Securities Inc. (the
Lead Underwriter), CIBC World Markets Inc., GMP Securities Limited and RBC Dominion Securities Inc. (the Lead Underwriter, CIBC World Markets Inc., GMP Securities Limited and RBC Dominion Securities Inc. are hereinafter
collectively referred to as the Underwriters and each individually, an Underwriter) understand that SMTC Manufacturing Corporation of Canada (the Company), an indirect wholly-owned subsidiary
of SMTC Corporation (SMTC), proposes to create, issue, offer and sell 33,350,000 special warrants (the Special Warrants), subject to the terms and conditions set out below, at a price of Cdn. $1.20 (the
Issue Price) per Special Warrant (the Offering). The total gross proceeds of the Offering to the Company will be Cdn. $40,020,000.



The Special Warrants will be issued pursuant to the provisions of a special warrant indenture and escrow agreement to be
dated the date hereof (the Special Warrant Indenture) and made between the Company and CIBC Mellon Trust Company (the Trustee). The specific attributes of the Special Warrants will be set forth in the Special
Warrant Indenture. The Special Warrant Indenture will provide, among other things, that holders of Special Warrants will be entitled to receive for each Special Warrant held, upon the conversion thereof and without payment of any additional
consideration, one unit (and including any amounts forming part of a Penalty Unit (as defined below), a Unit) comprised of one exchangeable share in the capital of the Company (including any such shares forming part of a Penalty
Unit, a Special Warrant Share) and one-half of one exchangeable share purchase warrant (each whole warrant, a Warrant) for each Special Warrant held, subject to adjustment as described in Section 5 and in
certain other circumstances specified in the Special Warrant Indenture. The Special Warrant Indenture will otherwise be in such form and contain such terms as may be approved by the Underwriters, the Company, SMTC and their respective counsel. The
Special Warrants will be exercisable by the holders thereof, at any time on or before 5:00 p.m. (Toronto time) on the date (the Special Warrant Expiry Date) that is the earlier of: (i) the sixth Business Day (as defined below)
after the date that a receipt is issued by the securities regulatory authority in the Qualifying Jurisdiction (as defined below) in which the holder is resident



---

(holders of Special Warrants resident outside of Canada will be deemed to be residents of the Province of Ontario for
these purposes) for a (final) prospectus qualifying the distribution of the Units issuable upon exercise of the Special Warrants (the Prospectus Qualification Date); and (ii) the first Business Day following the date that is 12
months after the Closing Date (as defined below). Special Warrants not exercised prior to the Special Warrant Expiry Date will be deemed to have been exercised by the Trustee on behalf of the holders thereof, without any further action on the part
of the holders, at 4:59 p.m. (Toronto time) on the Special Warrant Expiry Date.



The exchangeable shares in the capital of the Company are referred to herein as Exchangeable Shares; the Exchangeable Shares issuable upon the conversion of the Warrants are referred to herein as
Warrant Shares; the common shares in the capital of SMTC are referred to herein as Common Shares; and the Common Shares issuable upon the exchange of the Exchangeable Shares are referred herein as
Underlying Common Shares.



The Warrants will
be issued pursuant to the provisions of a warrant indenture to be dated the date hereof (the Warrant Indenture) and made between the Company and the Trustee. The specific attributes of the Warrants will be set forth in the Warrant
Indenture. The Warrant Indenture will provide, among other things, that each whole Warrant will entitle the holder thereof to acquire one Exchangeable Share for each Warrant held, subject to adjustment in certain other circumstances specified in the
Warrant Indenture, and will be exercisable by the holders thereof at any time on or before 5:00 p.m. (Toronto time) on the date (the Warrant Expiry Date) that is the first Business Day following the date that is five years after
the Closing Date at a price of Cdn. $1.85 per Warrant Share, subject to adjustment in certain circumstances specified in the Warrant Indenture. The Warrant Indenture shall otherwise be in such form and contain such terms as may be approved by the
Underwriters, the Company, SMTC and their respective counsel.



Each Special Warrant Share and Warrant Share will be exchangeable at the option of the holder for one Underlying Common Share, subject to adjustment in certain circumstances specified in the Support Agreement. On or after July 27, 2015,
subject to acceleration in certain circumstances, the Company or one of its affiliates will redeem all of the outstanding Exchangeable Shares by delivering Common Shares to holders of the Exchangeable Shares on a one-for-one basis, subject to
adjustment in certain circumstances.



Based on the foregoing
and subject to the terms and conditions set out below, the Underwriters offer to purchase severally in the respective percentages set out in Section 17, and by its acceptance hereof the Company hereby agrees to issue and sell to the Underwriters,
all but not less than all of, the Special Warrants at the Closing Time (as defined below).



In consideration of the Underwriters agreement to purchase the Special Warrants that will result from acceptance by the Company and SMTC of this offer, and in consideration of the other services to be rendered
by the Underwriters in connection therewith, including assisting in preparing documentation relating to the Special Warrants, including the Preliminary Prospectus and the Prospectus (each as defined below), and performing administrative work in
connection with the distribution of the Special Warrants, the Company and SMTC, jointly and severally, agree to pay to the Underwriters at the Closing Time a cash fee (the Underwriters Fee) of $2,401,200, representing $0.072
(exclusive of federal goods and services tax, if applicable) for each Special Warrant issued and sold at the Closing Time.

It is acknowledged and agreed that the Underwriters may arrange for substituted purchasers (the
Substituted Purchasers) to purchase Special Warrants on their behalf, it being agreed and understood that to the extent that the Underwriters do not arrange for Substituted Purchasers the purchase obligations hereunder shall
continue to be obligations of the Underwriters and if, and only to the extent that, Substituted Purchasers purchase Special Warrants at the Closing Time, the obligations of the Underwriters to do so will be reduced, rateably in accordance with the
respective percentages set out in Section 17, by the number of Special Warrants purchased from the Company by Substituted Purchasers. It is acknowledged and agreed that the Underwriters will be permitted to appoint other registered dealers (or other
dealers duly qualified in their respective jurisdictions) (a Selling Firm) as their agents to assist in the Offering of Special Warrants to Substituted Purchasers and the Underwriters may determine the remuneration to such other
dealers appointed by them, provided that any remuneration payable to any Selling Firm shall be for the account of the Underwriters and the Company and SMTC shall not be required to pay to the Underwriters more than the Underwriters Fee.

be held in escrow pursuant to the terms of the Special Warrant Indenture. The Trustee will hold the

approval referred to herein as the Shareholder Approval). SMTC hereby covenants and agrees that it and its management and board of directors will seek and (subject to fiduciary duties) publicly recommend such approval forthwith,
and will use its commercially reasonable best efforts to hold a meeting (a Shareholders Meeting) of its shareholders for such purpose within 60 days following the Closing Date, but in any event no later than 90 days following the
Closing Date (the Shareholder Approval Deadline).

Warrants will terminate and the Company hereby grants to the Underwriters, in the respective percentages set out in Section 17, a non-assignable (except to a Substituted Purchaser) option (the Option) to purchase, at a price of

an amount equal to one-half of the difference between (A) the average market price of the Exchangeable Shares based on the closing price of the Exchangeable Shares on the TSX for the period that is ten trading days leading up to the date of the
Shareholders Meeting called to approve the Offering, and (B) Cdn. $1.20, such payment to be made in immediately available funds on completion of such Alternative Business Transaction.

Statement becomes effective does not occur on or before the Registration Qualification Deadline, each Special Warrant exercised after the Prospectus Qualification Deadline will entitle the holder thereof to receive 1.1 Units without payment of

therefor) (with the additional Units issuable in such circumstance being referred to herein as the Penalty Units) and each of the Company and SMTC will continue to use its commercially reasonable best efforts to (i) file, clear,

| | (i) | any statement or information (other than the Underwriters Disclosure) contained in the Preliminary Prospectus, the Prospectus, the Registration Statement, any Amendment or any
Supplementary Material that may be filed by or on behalf of the Company or SMTC under the applicable Canadian Securities Laws and the applicable securities laws of the United States in connection with the Offering being or alleged to be a
misrepresentation or untrue or any omission or alleged omission to state therein any fact or information (other than Underwriters Disclosure), required to be stated therein or necessary to make any statement therein not misleading in light of
the circumstances under which it was made;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If any matter or thing contemplated by this Section 14 shall be asserted against any Person in respect of
which indemnification is or might reasonably be considered to be provided, such Person (the Indemnified Person) shall notify the party from whom indemnity is being sought (the Indemnifying Party) as soon as
possible of the nature of such claim, and the Indemnifying Party shall be entitled, but not required, to assume the defence of any suit brought to enforce such claim; provided, however, that the defence shall be through legal counsel reasonably
acceptable to the Indemnified Person. The omission to so notify the Indemnifying Party will not relieve it from liability which it may have to any Indemnified Person provided that the Indemnifying Party is not materially prejudiced by such omission.



| | (b) | In any claim referred to in subsection 14(a) hereof, the Indemnified Person shall have the right to retain other legal counsel to act on his, her or its behalf provided that the
fees and disbursements of such other legal counsel shall be paid by the Indemnified Person unless:
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | the Indemnifying Party and the Indemnified Person shall have mutually agreed to the retention of the other legal counsel;
| | --- | -------------------------------------------------------------------------------------------------------------------------



| | (ii) | the Indemnifying Party fails to defend such claim within a reasonable period of time; or
| | ---- | ----------------------------------------------------------------------------------------



| | (iii) | the Indemnified Person and Indemnifying Party are parties to any such claims and the representation of both parties by the same legal counsel would be inappropriate due to the
actual or potential differing interests between them;
| | ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



in which event such fees and disbursements shall be paid on an on-going basis by the Indemnifying Party to the extent that such fees have been reasonably incurred provided that in no event shall the Company or SMTC be responsible for the
fees and expenses of more than one separate legal counsel in respect of all Indemnified Persons.



| | (c) | The rights of indemnity contained in this Section 14 shall not enure to the benefit of any Indemnified Person if the Underwriters were provided with a copy of any Amendment which
corrects any untrue statement or omission or alleged omission which is the basis of such claim and which is required, under the applicable Canadian Securities Laws and the applicable securities laws of the United States, to be delivered to such
Person by the Underwriters and if the Underwriters do not so deliver the Amendment within five days of the Underwriters receipt.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | The Company and SMTC hereby waives any right to recover contribution from the Underwriters with respect to any liability of the Company and SMTC by reason of or arising out of any
misrepresentation contained in the Preliminary Prospectus, the Prospectus, the Registration Statement, any Amendment or any Supplementary Material; provided, however, that such waiver shall not apply in respect of liability caused or incurred by
reason or arising out of any misrepresentation which is based upon or results from the Underwriters Disclosure.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (e) | If for any reason the indemnification provided for in subsection 14(a) is unavailable, in whole or in part, to an Indemnified Person in respect of any losses, claims, damages,
liabilities, costs or expenses (or claims, actions, suits or proceedings in respect thereof) referred to in subsection 14(a), and subject to the restrictions and limitations referred to therein, the Indemnifying Party shall contribute to the amount
paid or payable (or, if such indemnity is unavailable only in respect of a portion of the amount so paid or payable, such portion of the amount so paid or payable) by such Indemnified Person as a result of such losses, claims, damages, liabilities,
costs or expenses (or claims, actions, suits or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Party on the one hand and the Underwriters on the other hand from the
distribution of the Special Warrants provided that an Underwriter shall not in any event be liable to contribute, in the aggregate, any amount in excess of the amount of the Underwriters Fee paid to it pursuant hereto.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



The relative benefits received by the
Indemnifying Party on the one hand and the Underwriters on the other hand shall be deemed to be in the proportion that the total proceeds received from the distribution of the Special Warrants (net of the Underwriters Fee) is to the
Underwriters Fee in respect of the sale of the Special Warrants. The amount paid or payable by an Indemnified Person as a result of such losses, claims, damages, liabilities, costs or expenses (or claims, actions, suits or proceedings in
respect thereof) referred to above shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Person in connection with investigating or defending any such losses, claims,. damages, liabilities, costs or expenses
(or claims, actions, suits or proceedings in respect thereof), whether or not resulting in any such action, suit, proceeding or claim.



| | (f) | No admission of liability and no settlement of any claims, actions, suits or proceedings in respect of any losses, claims or liabilities referred to in this Section 14 shall be made
without the consent of the Indemnified Person affected, such consent not to be unreasonably withheld. No admission of liability shall be made by an Indemnified Person without the consent of the Indemnifying Party and it shall not be made liable for
any settlement of any such claim, action, suit or proceeding made without its consent, such consent not to be unreasonably withheld.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (g) | The indemnity and contribution obligation of the Indemnifying Party hereof shall be in addition to any liability which the Indemnifying Party may have, shall, to the extent that the
indemnity contained in subsection 14(a) hereof is given in favour of Persons who are not parties to this Agreement, be held by the Underwriters in trust for the Persons in favour of whom such indemnities are given and may be enforced directly by
such Persons and be binding and enure to the benefit of any successors, assigns, heirs and personal representatives of an Indemnified Person.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 37 -



---

| | (h) | If a court of competent jurisdiction in a final judgment determines that any person has engaged in any fraud, fraudulent misrepresentation, wilful misconduct or gross negligence,
such person shall not be entitled to claim contribution from any other person who has not engaged in such fraud, fraudulent misrepresentation, wilful misconduct or gross negligence.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|15. | Expenses
|--- | --------



Whether or not the purchase and sale of the Special Warrants shall be completed as contemplated by this Agreement, all reasonable costs and expenses of or
incidental to the issue and delivery of the Special Warrants to the Substituted Purchasers and of or incidental to all matters in connection with the transactions set out in this Agreement shall be borne by the Company and SMTC, including, without

out-of-pocket costs and expenses, and the reasonable fees and disbursements of the Underwriters legal counsel and any Selling Firms. All reasonable costs and expenses incurred by the Underwriters prior to the Closing Date shall be deducted
from the gross proceeds of the Offering at the Time of Closing. All reasonable costs and expenses incurred by the Underwriters on or after the Closing Date, including the reasonable fees and disbursements of the Underwriters legal counsel in
connection with the Prospectus and related due diligence, shall be reimbursed by the Company and SMTC within 15 days of receiving an invoice therefore.



|16. | Termination
|--- | -----------



| | (a) | Material Change
| | --- | ---------------



If, prior to the Closing Time, there should occur any material change or a change in any material fact (including the discovery by the Underwriters of any
material fact that was not disclosed previously by the Company or SMTC) in the business, operations, capital, affairs or prospects of the Company or SMTC or any of their affiliates, which results or, in the opinion of any of the Underwriters, might
reasonably be expected to result to a materially adverse effect on the market price or value of the Exchangeable Shares or Common Shares, any of the Underwriters shall be entitled, at its option, in accordance with subsection 16, to terminate its
obligations under this Agreement by written notice to that effect given to the other Underwriters and the Company at any time prior to the Closing Time.

If any inquiry, action, suit, investigation or other proceeding (whether formal or informal) is commenced, announced or threatened or any order is made by
any federal, provincial or other governmental department, commission, board, bureau, agency or instrumentality including, without limitation, the TSX or the NASDAQ or any securities regulatory authority (other than any such inquiry, action, suit
investigation or other proceeding or order relating solely to any of the Underwriters) or any law or regulation is enacted or changed which in the reasonable opinion of the Underwriters operates to prevent or restrict the trading of the Exchangeable
Shares or the Common Shares or materially and adversely affects or could be expected to materially and adversely affect the market price or value of the Exchangeable Shares or the Common Shares, any of the Underwriters shall be entitled, at its
option and in accordance with subsection 16, to terminate its obligations under this Agreement by notice to that effect given to the other Underwriters and the Company at any time prior to the Closing Time.

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



If there should develop, occur or come into effect or existence any event, action, state, condition or major financial occurrence of national or
international consequence, any acts of terrorism or hostilities or escalation thereof or other calamity or crises, or any law or regulation which in the reasonable opinion of any Underwriter, materially adversely affects, or could be expected to
materially adversely affect, the financial markets in Canada or the United States or the business, operations, capital, affairs or prospects of SMTC and the Subsidiaries taken as a whole, any of the Underwriters shall be entitled at its option, in

Each of the Company and SMTC agree that all material terms and conditions of this Agreement shall be construed as conditions and complied with so far as
they relate to acts to be performed or caused to be performed by it, that it will use its commercially reasonable best efforts to cause such conditions to be complied with, and that any breach or failure by the Company or SMTC to comply with any
such conditions shall entitle any of the Underwriters to terminate their obligations to purchase the Special Warrants or to refuse to sign the certificate of Underwriters in the Prospectus (provided that, for greater clarity, failure to comply with
any such material term or condition entitles such Underwriter to so refuse pursuant to Section 12 of this Agreement), by notice to that effect given to the other Underwriters, the Company and SMTC at or prior to the Closing Time, unless otherwise
expressly provided in this Agreement. The Underwriters may waive, in whole or in part, or extend the time for compliance with, any terms and conditions without prejudice to their rights in respect of any other of such terms and conditions or any
other or subsequent breach or non-compliance, provided that any such waiver or extension shall be binding upon the Underwriters only if such waiver or extension is in writing and signed by all of the Underwriters.

may arise after such termination under Section 16. A notice of termination given by an Underwriter under subsections 16(a), 16(b), 16(c) and 16(d) shall not be binding upon any other Underwriter.
