of the date of each Tranche A Notice of Borrowing issued in connection therewith) in connection with the Tranche A Loan. All Tranche B Advances under the Finnvera Facility B shall be in Canadian Dollars alone. The Finnvera Facility B
will not revolve and any amount prepaid or repaid may not be reborrowed.



|3. | USE
|-- | ---

All Tranche B Advances made by the Tranche B Lenders to the Borrower under the Finnvera Facility B in accordance with the provisions of this Agreement shall be used by the Borrower to, without
duplication, (i) finance up to the CAD Equivalent of (x)85% of the Purchase Price and (y)costs for local services up to a maximum of 30% of the Purchase Price by way of reimbursement to the Borrower for eligible
payments made by the Borrower to NSN under the NSN Contract; (ii) pay up to 100% of the upfront portion of the ECA Premium B from the proceeds of the first Tranche B Advance; and (iii) pay all other amounts approved by Finnvera and
owed in connection with the NSN Contract; the whole subject to and in accordance with the terms and conditions of this Agreement.



|4. | ADVANCES AND OPERATION OF ACCOUNTS
|-- | ----------------------------------



|4.1. | Tranche B Notice of Borrowing
|---- | -----------------------------

Subject to the applicable provisions of this Agreement but not more than once per calendar month, the Borrower shall be entitled to request multiple Tranche B Advances under the
Finnvera Facility B, to be made on any Business Day during the Availability Period and in accordance with the payment program set forth in the NSN Contract, up to the maximum amount of the Tranche B Credit, upon delivery of an irrevocable
written Tranche B Notice of Borrowing to the Finnvera Facility B Agent at or before 3:00 P.M. (London, England time) at least four (4) Business Days prior to the date of the proposed Tranche B Advance.

made by a Foreign Tranche B Lender in accordance with Section 4.6 shall be in the form of Tranche B LIBOR Advances.

|4.3. | Notice of New Tranche B Designated Period
|---- | -----------------------------------------

Upon the expiration of any Tranche B Designated Period applicable to any Tranche B LIBOR Advance or any Tranche B CDOR Advance, the Borrower shall have the option to
request the continuation of all or any portion (in minimum amounts of Cdn.$1,000,000 or such smaller amount corresponding to the Tranche B LIBOR Advance Amount or the Tranche B CDOR Advance Amount, respectively) of such Tranche B
Advance on the Tranche B Rollover Date upon delivery of an irrevocable written Notice of New Tranche B Designated Period to the Finnvera Facility B Agent at or before 3:00 P.M. (London, England time) at least four
(4) Business Days prior to the date of the Tranche B Rollover Date. Except in respect of the whole or a portion of the Tranche B Advance Amount for which the Borrower has delivered a Notice of Repayment in accordance with the
provisions of Section 7.2, if the Borrower has not delivered a Notice of New Tranche B Designated Period in a timely manner in accordance with the provisions of this Section 4.3, the Borrower shall be deemed to have chosen a new
Tranche B Designated Period of 6 months (or such shorter period expiring on the next Repayment Date). For greater certainty, if only a portion of a Tranche B Advance is continued under this Section 4.3, the portion not so
continued shall be prepaid and cancelled.



|4.4. | Determination of Interest
|---- | -------------------------

The Finnvera Facility B Agent shall determine the Tranche B LIBOR and the CDOR Rate which will be in effect on the date of the Tranche B Advance or the Tranche B Rollover Date, as the
case may be (which, in each case, must be a Business Day), with respect to the Tranche B LIBOR Advance Amount and the Tranche B CDOR Advance Amount, respectively, having a maturity of 30 to 183 days (during the Availability Period) or
1, 3 or 6 months (during the period of 24 months from the Signing Date) or 3 or 6 months (thereafter), as requested by the Borrower and subject to availability, from the date of the Tranche B Advance or the Tranche B Rollover
Date, as the case may be. However, if the Borrower has not delivered a notice to the Finnvera Facility B Agent in a timely manner in accordance with the provisions of Section 4.1 or 4.3, as the case may be, the Borrower shall be deemed to
have chosen a Tranche B Designated Period of 6months (or such shorter period expiring on the next Repayment Date).

Notwithstanding the foregoing, each Tranche B Advance other than the initial Tranche B Advance shall have a Tranche B Designated Period expiring on the next Tranche B Rollover Date.



|4.5. | Operation of Accounts
|---- | ---------------------

The Finnvera Facility B Agent shall maintain in its books at the Finnvera Facility Agency Branch a record of the Tranche B Loan attesting as to the total of the Borrowers indebtedness to
the Tranche B Lenders. These accounts or registers shall constitute, in the absence of manifest error, prima facie proof of the total amount of the indebtedness of the Borrower to the Tranche B Lenders, of the date of any
Tranche B Advance made to the Borrower and of the total of all amounts paid by the Borrower from time to time with respect to principal and interest owing on the Tranche B Loan and the fees and other sums exigible in connection with the
Finnvera Facility B.



|4.6. | Apportionment of Tranche B Advances
|---- | -----------------------------------

The amount of each Tranche B Advance will be apportioned among the Tranche B Lenders by the Finnvera Facility B Agent by reference to the Tranche B Commitment of
each Tranche B Lender, as such Tranche B Commitment shall be immediately prior to the making of any Tranche B



- 4 -

Advance. If any amount disbursed by the Finnvera Facility B Agent to the Borrower is not in fact made available to the Finnvera Facility B Agent by a Tranche B Lender, the Finnvera
Facility B Agent shall be entitled to recover such amount (together with interest thereon at the rate determined by the Finnvera Facility B Agent as being its cost of funds in the circumstances) on demand from such Tranche B Lender
or, if such Tranche B Lender fails to reimburse the Finnvera Facility B Agent for such amount, on demand from the Borrower.



|4.7. | Limitations on Advances
|---- | -----------------------



| | 4.7.1. | The undrawn Tranche B Credit available under the Finnvera Facility B shall cease to be available at the expiry of the Availability Period.
| | ------ | ------------------------------------------------------------------------------------------------------------------------------------------



| | 4.7.2. | The aggregate principal amount of each Tranche B Advance (other than the initial Tranche B Advance) shall not exceed the CAD Equivalent
(determined as of the date of the Tranche B Notice of Borrowing issued in connection with such Tranche B Advance) of (i) 85% of the portion of the Purchase Price for which such Tranche B Advance is made and (ii) costs for
local services up to a maximum amount which, when combined with all amounts previously disbursed by the Tranche B Lenders in reimbursement of costs for local services, does not exceed 30% of the portion of the Purchase Price paid to date
(collectively, the Maximum Amount) and, in the case of the initial Tranche B Advance only, the sum of the Maximum Amount and up to 100% of the upfront portion of the ECA Premium B.
| | ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.8. | Notices Irrevocable
|---- | -------------------

Any notice given to the Finnvera Facility B Agent in accordance with Article 4 may not be revoked or withdrawn.



|4.9. | Market for Tranche B LIBOR Advances and Tranche B CDOR Advances
|---- | ---------------------------------------------------------------



| | 4.9.1. | If at any time or from time to time as a result of market conditions, (i) there exists no appropriate or reasonable method to establish the
Tranche B LIBOR or the CDOR Rate for a Tranche B LIBOR Advance Amount or a Tranche B CDOR Advance Amount, respectively, or a Tranche B Designated Period, or (ii) the Finnvera Facility B Agent receives notification from
two or more Tranche B Lenders whose Tranche B Commitments exceed, in the aggregate, 20% of the Tranche B Credit, that the Tranche B LIBOR or the CDOR Rate does not accurately reflect its Cost of Funds, then the relevant
Tranche B Lenders shall, prior to the date of a Tranche B Advance or the Tranche B Rollover Date, so advise the Finnvera Facility B Agent and shall thereupon not be obliged to honor any Tranche B Notices of Borrowing or any
Notices of New Tranche B Designated Period and the Borrowers option to request Tranche B LIBOR Advances or Tranche B CDOR Advances or any rollovers thereof, as the case may be, shall thereupon be suspended upon notice by the
Finnvera Facility B Agent to the Borrower, and, until such time as the Finnvera Facility B Agent has determined that the circumstances having given rise to such suspension no longer exist, in respect of which determination the Finnvera
Facility B Agent shall advise the Borrower within a reasonable delay, the rate of interest applicable to such Tranche B Lenders portion of any Tranche B Advance shall be calculated and payable on a Cost of Funds Basis plus a
margin of (a) 1.40%, in the case of rollovers of Tranche B Advances which were originally Tranche B CDOR Advances or in the case of new Tranche B Advances which would otherwise have been Tranche B CDOR Advances in accordance
with the

| | provisions of Section 4.6, or (b) 1.325%, in the case of rollovers of Tranche B Advances which were originally Tranche B LIBOR Advances or in the case of new Tranche B
Advances which would otherwise have been Tranche B LIBOR Advances in accordance with the provisions of Section 4.6. For the purposes of paragraph (ii) of this Section 4.9, a Tranche B Lender shall notify the Finnvera
Facility B Agent of its Cost of Funds as soon as practicable and in any event before interest is due to be paid in respect of the relevant Tranche B Advance.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4.9.2. | If the events described in clause (i) or (ii) of subsection 4.9.1 above occur and the Finnvera Facility B Agent or the Borrower
so requires, the Finnvera Facility B Agent and the Borrower shall enter into negotiations (for a period of not more than thirty (30) days) with a view to agreeing on a substitute basis for determining the rate of interest payable to each
Tranche B Lender affected by such above-mentioned events. Any alternative basis agreed upon pursuant to the above shall, with the prior consent of all of the Tranche B Lenders, be binding on all parties, it being agreed that such
alternative basis shall apply only to the Tranche B Lenders affected by the relevant events described in such clause (i) or (ii).
| | ------ | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4.9.3. | For greater certainty, if no such agreement on an alternative basis is reached in accordance with the provisions of subsection 4.9.2 above, the
provisions of 4.9.1 shall apply.
| | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.10. | Suspension of Tranche B LIBOR Advances and Tranche B CDOR Advances
|----- | ------------------------------------------------------------------

If Canadian Dollar deposits are not available to the Foreign Tranche B Lenders in the ordinary course of business in
amounts sufficient to permit them to make or continue a Tranche B Advance for a Tranche B Designated Period, the Foreign Tranche B Lenders shall, prior to the date of a Tranche B Advance or the Tranche B Rollover Date, so
advise the Finnvera Facility B Agent and thereupon be relieved from their obligation to make or continue a Tranche B Advance until such time as such funds become available in sufficient amounts, but they shall comply with the provisions of
Section 4.11.



|4.11. | Specific Clause with Regard to Foreign Tranche B Lenders
|----- | --------------------------------------------------------

In the event of a suspension of the Borrowers right to request Tranche B Advances (including conversions and
extensions thereof) from one or more Foreign Tranche B Lenders under Section 4.10 (each a Tranche B Affected Lender), each Tranche B Affected Lender shall, concurrently with the notice described in
Section 4.10, seek alternative sources of funding the Tranche B Advances and, if sufficient funds are obtained, shall notify the Borrower as to when such funds will be available for Tranche B Advances. On the date indicated in such
latter notice, the Tranche B Affected Lender shall be deemed to have made a Tranche B Advance with interest payable on a Cost of Funds Basis.

If within 5 Business Days following the notice described in Section 4.10, there remain one or more Tranche B Affected Lenders who have not been deemed to have made a Tranche B Advance
on a Cost of Funds Basis under the preceding paragraph, such Tranche B Affected Lender (a Tranche B Incapable Lender) shall (i) provide an additional notice to the Finnvera Facility B Agent and the Borrower of
such fact and (ii) make Tranche B Advances in US Dollars on a Tranche B LIBOR Basis, and the parties will negotiate such amendments hereto as may be required to give full effect to such intention, it being understood that the Borrower
alone will bear all foreign exchange risks.

|4.12. | Limits on Tranche B LIBOR Advances and Tranche B CDOR Advances

|4.13. | Exclusion of Finnvera Facility B Agent, Security Agent and Tranche B Lenders Liability in respect of NSN Contract
|----- | -----------------------------------------------------------------------------------------------------------------

It is expressly understood and agreed by the Borrower, the Finnvera Facility B
Agent, the Security Agent and the Tranche B Lenders that there is no contractual relationship, either express or implied, between the Finnvera Facility B Agent, the Security Agent and the Tranche B Lenders, on the one hand, and the
Borrower, NSN or any other Person supplying any work, services or material in connection with the NSN Contract, on the other hand, and that the Finnvera Facility B Agent, the Security Agent and the Tranche B Lenders shall not be liable to
the Borrower, NSN or any such other Person in connection with the NSN Contract. The Borrower is not and shall not be the agent of the Finnvera Facility B Agent, the Security Agent or the Tranche B Lenders for any purpose. There shall be no

|5.3. | Payment of Interest

Finnvera Facility B Agent, for the account of the relevant Tranche B Lenders, in arrears on the last day of the Tranche B Designated Period.

If the relevant Tranche B Designated Period is not equal to 1, 2, 3 or 6 months, then the Tranche B LIBOR or the CDOR Rate, as the case may be, shall be determined by
the application of straight line interpolation (rounding upwards, if necessary, to the nearest multiple of 0.01%) by reference



- 7 -

to two Tranche B LIBOR or CDOR Rates, as applicable, one of which shall be the rate per annum for the period shorter than the stated term by the least number of days, and the other of which shall
be the rate per annum for the period which is longer than the stated term by the least number of days.

|5.5. | Arrears of Interest
|---- | -------------------

Any arrears of interest or principal payable by the Borrower to the Finnvera Facility B Agent or the Tranche B Lenders in connection with the Tranche B Loan shall bear interest at the Default Rate.



|5.6. | Maximum Interest
|---- | ----------------

The amount of the interest or fees exigible in applying this Agreement shall not exceed the maximum rate permitted by Law. Where the amount of such interest or such fees is greater than such maximum rate,

The Borrower shall pay to the Finnvera Facility B Agent, for the account of the Tranche B Lenders, a commitment fee (the Commitment Fee) in accordance with the terms and conditions of

For the purposes of the Interest Act (Canada), any amount of interest or fees calculated herein using 360 or 365 days per year and expressed as an annual rate is equal to the said rate of
interest or fees multiplied by the actual number of days comprised within the calendar year, divided by 360 or 365, as the case may be. The parties agree that all interest in this Agreement will be calculated using the nominal rate method and not
the effective rate method, and that the deemed re-investment principle shall not apply to such calculations. In addition, the parties acknowledge that there is a material distinction between the nominal and effective rates of interest and that they
are capable of making the calculations necessary to compare such rates.



|6. | ILLEGALITY, INCREASED COSTS AND INDEMNIFICATION
|-- | -----------------------------------------------



|6.1. | Illegality, Increased Costs
|---- | ---------------------------

If a Tranche B Lender, acting reasonably, determines (which determination shall be attested to by a certificate submitted to the Borrower by the Tranche B Lender with a copy to the Finnvera
Facility B Agent and which shall be final and binding between the parties hereto in the absence of manifest error) that (a) the adoption by a governmental or international authority (including the Bank for International Settlements (the
BIS)) of a law, directive, requirement or guideline, whether or not having the force of law, (b) any modification to a law, directive or guideline, whether or not having the force of law, or to the interpretation or
application of same by a tribunal or governmental or international authority (including the BIS) or other body charged with such interpretation or application, or (c) any quashing by a tribunal or other governmental or international authority
or body (including the BIS) of an interpretation of any law, directive, requirement or guideline, whether or not having the force of law:



| | 6.1.1. | has rendered or will render it illegal or contrary to any law, directive or guideline for any of the Tranche B Lenders to maintain or to give
effect to all or part of their obligations stipulated in this Agreement, including the obligation to make or maintain all or any part of a Tranche B Advance pursuant to the terms hereof, then the obligation of such Tranche B Lender(s) to
maintain or to give effect to such part of its or their obligations will become null and, subject to the provisions of the particular law, directive or guideline and of Section 6.2 with respect to losses, costs and expenses, if the
Tranche B Loan affected is a Tranche B CDOR Advance, the Borrower may convert the principal amount thereof into an advance bearing interest on a Cost of Funds Basis. If the Tranche B Loan affected is a Tranche B LIBOR Advance,
the provisions of Section 4.11 shall apply. In either case, the Borrower shall pay the interest accrued thereon, or may reimburse the particular Tranche B CDOR Advance or Tranche B LIBOR Advance, as the case may be, in whole with
interest accrued thereon. Such conversion or reimbursement shall be made at the expiry of the relevant Tranche B Designated Period of any then outstanding Tranche B LIBOR Advances or Tranche B CDOR Advances, as the case may be, or, if
in the judgment of the Tranche B Lender expressed to the Finnvera Facility B Agent in the certificate referred to above, an immediate conversion or reimbursement is necessary, immediately upon demand by the Finnvera Facility B Agent,
subject to the payment by the Borrower of breakage costs, if any; or
| | ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

applicable any special tax, reserve, deposit, capital adequacy or similar requirement with respect to the assets held

| | by, deposited at or used for the purchase of funds, or to the loans made by the Tranche B Lenders, or (b) changes the basis of taxation on payments made to the Tranche B Lenders
under this Agreement (other than a change affecting the taxes based on net profits of the Tranche B Lenders), or (c) imposes upon the Tranche B Lenders any other monetary conditions or restrictions with respect to this Agreement, all
or any part of a Tranche B Loan, as the case may be, or any other document, effect or operation contemplated hereby, and if the result of any of the foregoing is to increase the cost to such Tranche B Lender of making or maintaining its
Tranche B Commitment or any Tranche B Advance, or to reduce any amount otherwise receivable by such Tranche B Lender hereunder with respect thereto, then, in any such case, the Borrower shall promptly pay to such Tranche B
Lender, within 10 Business Days from demand, such additional amounts necessary to compensate such Tranche B Lender for such additional cost or reduced amount receivable as is determined in good faith by such Tranche B Lender. If a

limitation any loss or expense arising from interest or fees payable by such Tranche B Lender to lenders of funds obtained by it in order to make or maintain any Tranche B Advance and any loss or expense incurred in liquidating or
re-employing deposits from which such funds were obtained, which such Tranche B Lender may sustain or incur as a consequence of any (a) default by the Borrower in the payment when due of the amount of or interest on any Tranche B Loan
or in the payment when due of any other amount hereunder, (b) default by the Borrower in obtaining a Tranche B Advance after the Borrower has given notice hereunder that it desires to obtain such Tranche B Advance, (c) default by

promptly notify the Borrower of the event by reason of which it has become so entitled and reasonable particulars of the related loss or expense, provided that the failure to do so promptly shall not prejudice such Tranche B Lenders right
to claim hereunder.

Without prejudice to the survival or termination of any other agreement of the Borrower
under this Agreement, the obligations of the Borrower under this Section 6.2 shall survive the payment of principal and interest on all Tranche B Loans and the termination of the Tranche B Credit.

Tranche B LIBOR Advance or Tranche B CDOR Advance, respectively, which cash collateral shall be deemed a repayment of such Tranche B Advance and shall be held by the Finnvera Facility B Agent in an interest bearing account and

in (i) or (ii) above in any way restrict the rights or remedies of the Finnvera Facility B Agent under the ECA Guarantee in respect of any amounts already disbursed to the Borrower by way of Tranche B Advances and any interest accrued
thereon (such amounts, the Affected Amounts), the Borrower shall, within 10 days following the date on which the Finnvera Facility B Agent makes a written demand therefor, find a replacement guarantee or other instrument
satisfactory to all Tranche B Lenders, unless within such 10 day period all Tranche B Lenders confirm in writing that the Borrower is released from its obligations under this covenant.

|11.4. | Future Guarantors
|----- | -----------------

The Borrower shall cause each Person that becomes a Wholly Owned Restricted Subsidiary of the Borrower following the Signing Date (a Future Guarantor) to become a Subsidiary Guarantor
hereunder and to execute and deliver to the Security Agent, for the rateable benefit of the Tranche B Lenders, a Subsidiary Guarantee in the form attached hereto as Schedule F and an opinion of counsel to such Wholly Owned Subsidiary, in
form and substance reasonably satisfactory to the Security Agent and the Tranche B Lenders. In addition, the Borrower shall not permit any of its Restricted Subsidiaries, directly or indirectly, to guarantee any other Indebtedness (including
Back-to-Back Debt) of the Borrower or any of its Restricted Subsidiaries unless such Restricted Subsidiary is a Subsidiary Guarantor or simultaneously executes and delivers the Subsidiary Guarantee referred to above, which Subsidiary Guarantee shall
be senior to or pari passu with such Subsidiarys guarantee of such other Indebtedness. For the purposes of this Section 11.4, capitalized terms used but not defined in Schedule G shall have the meanings ascribed to them in the
Trust Indenture.

event or circumstance which makes such statement, attestation, financial statement, report, data, representation or warranty misleading in any material respect is capable of being remedied, such action as may be required to remedy same shall not
have been completed within 15 days of the earlier of (a) the Finnvera Facility B Agent notifying the Borrower of such breach, or (b) the Borrower notifying the Finnvera Facility B Agent of the default in accordance with
subsection 11.1.2; or

| | 12.1.9. | if any Subsidiary Guarantee of a Significant Subsidiary (as defined in the Trust Indenture) ceases, or the Subsidiary Guarantees of any group of
Subsidiaries (as

Significant Subsidiary deny or disaffirm their obligations under their respective Subsidiary Guarantees.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|12.2. | Remedies
|----- | --------

If an Event of Default occurs under subsection 12.1.7 or 12.1.8, the Tranche B Loans shall immediately become due and exigible, without presentation, demand, protest or other notice of any
nature, to which the Borrower hereby expressly renounces. If any other Event of Default occurs, the Finnvera Facility B Agent may, at its option, and shall if required to do so by the Tranche B Lenders, declare immediately due and
exigible, without presentation, demand, protest or other notice of any nature, to which the Borrower hereby expressly renounces, notwithstanding any provision to the contrary effect in this Agreement:



| | 12.2.1. | the entire amount of the Tranche B Loan, in principal and interest. The Borrower shall not have the right to invoke against the Tranche B
Lenders any defence or right of action, indemnification or compensation of any nature or kind whatsoever; and
| | ------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 12.2.2. | an amount equal to the amount of losses, costs and expenses assumed by the Tranche B Lenders and referred to in Section 6.2; and
| | ------- | --------------------------------------------------------------------------------------------------------------------------------

the Tranche B Credit shall cease and as and from such time shall be cancelled, and the
Tranche B Lenders may exercise all of their rights and recourses under the provisions of this Agreement. For greater certainty, from and after the occurrence of any Default or Event of Default, the Tranche B Lenders shall not be obliged to
make any further Tranche B Advances under the Tranche B Credit.



|12.3. | Bankruptcy and Insolvency
|----- | -------------------------

If the Borrower files a notice of intention to file a proposal, or files a proposal under the Bankruptcy and Insolvency Act, or if the Borrower obtains the permission of the court to file a Plan of
Arrangement under the Companies Creditors Arrangements Act, and if a stay of proceedings is obtained or ordered under the provisions of either of those statutes, without prejudice to the Tranche B Lenders rights to contest
such stay of proceedings, the Borrower covenants and agrees to continue to pay interest on all amounts due to the Tranche B Lenders in accordance with the provisions hereof. In this regard, the Borrower acknowledges that permitting the Borrower
to continue to use the proceeds of the Tranche B Loan constitutes valuable consideration provided after the filing of any such proceeding in the same way that permitting the Borrower to use leased premises constitutes such valuable
consideration.



|12.4. | Notice
|----- | ------

Except where otherwise expressly provided herein, no notice or demand of any nature is required to be given to the Borrower by the Finnvera Facility B Agent, the Security Agent or the Tranche B
Lenders in order to put the Borrower in default, the latter being in default by the mere lapse of time granted to perform an obligation or by forfeiture of the term or by the simple occurrence of a Default or by any other cause provided for by law.



- 21 -



---

|12.5. | Relations with the Borrower
|----- | ---------------------------

Each of the Finnvera Facility B Agent and the Security Agent may grant delays, take security or renounce thereto, accept compromises, grant acquittances and releases and otherwise negotiate with the
Borrower as it deems advisable without in any way diminishing the liability of the Borrower or prejudicing the rights of the Tranche B Lenders.



|13. | JUDGMENT CURRENCY
|--- | -----------------



|13.1. | Rules of Conversion
|----- | -------------------

If for the purpose of obtaining judgment in any court or for any other purpose hereunder, it is necessary to convert an amount due, advanced or to be advanced hereunder from the currency in which it is
due (the First Currency) into another currency (the Second Currency) the rate of exchange used shall be that at which, in accordance with normal banking procedures, the Finnvera Facility B Agent could
purchase, in the Canadian money market or the Canadian exchange market, as the case may be, the First Currency with the Second Currency on the date on which the judgment is rendered, the sum is exigible or advanced or to be advanced, as the case may
be. The Borrower agrees that its obligations in respect of any First Currency due from it to the Tranche B Lenders in accordance with the provisions hereof shall, notwithstanding any judgment rendered or payment made in the Second Currency, be
discharged by a payment made to the Finnvera Facility B Agent on account thereof in the Second Currency only to the extent that, on the Business Day following receipt of such payment in the Second Currency, the Finnvera Facility B Agent
may, in accordance with normal banking procedures, purchase on the Canadian money market or the Canadian foreign exchange market, as the case may be, the First Currency with the amount of the Second Currency so paid or which a judgment rendered
exigible; and if the amount of the First Currency which may be so purchased is less than the amount originally due in the First Currency, the Borrower agrees as a separate and independent obligation and notwithstanding any such payment or judgment
to indemnify the Tranche B Lenders against such deficiency.



|13.2. | Determination of an Equivalent Currency
|----- | ---------------------------------------

If, in their discretion, the Tranche B Lenders or the Finnvera Facility B Agent choose or, pursuant to the terms of this Agreement, are obliged to choose the equivalent in
Canadian Dollars of any securities or amounts expressed in US Dollars or the equivalent in US Dollars of any securities or amounts expressed in Canadian Dollars, the Finnvera Facility B Agent, in accordance with the conversion rules as
stipulated in Section 13.1.



| | 13.2.1. | on the date indicated in the Tranche B Notice of Borrowing as the date of a request for a Tranche B Advance; and
| | ------- | ----------------------------------------------------------------------------------------------------------------



| | 13.2.2. | at any other time which in the opinion of the Tranche B Lenders is desirable,
| | ------- | -----------------------------------------------------------------------------

may, using the spot rate of the Finnvera Facility B Agent on such date, determine the equivalent in Canadian Dollars or
in US Dollars, as the case may be, of any security or amount expressed in the other currency pursuant to the terms hereof. Immediately following such determination, the Finnvera Facility B Agent shall inform the Borrower of the conclusion which
the Tranche B Lenders have reached.



- 22 -



---

|14. | ASSIGNMENT
|--- | ----------



|14.1. | Assignment by the Borrower
|----- | --------------------------

The rights of the Borrower under the provisions hereof are purely personal and may not be transferred or assigned, and the Borrower may not transfer or assign any of its obligations, such assignment being
null and of no effect opposite the Tranche B Lenders and rendering any balance outstanding of the amounts referred to in Section 12.2 immediately due and exigible at the option of the Tranche B Lenders and further releasing the
Tranche B Lenders from any obligation to make any further Tranche B Advances under the provisions hereof.



|14.2. | Assignments and Transfers by the Tranche B Lenders
|----- | --------------------------------------------------

in Canada (the Tranche B Assignee) in accordance with this Article up to 100% of its rights, benefits and obligations hereunder with the prior written consent of the Borrower, which shall not be unreasonably withheld or
delayed. After the occurrence of an Event of Default, any Tranche B Lender may transfer all or any part of its rights, benefits and obligations hereunder to any Person, without the consent of the Borrower, but upon notice to the Finnvera
Facility B Agent and the Borrower and subject to the consent of Finnvera.
| | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 14.2.2. | Notwithstanding subsection 14.2.1, each Tranche B Lender shall be entitled to assign or transfer, at its own cost and without the consent
of the Borrower, in accordance with the other provisions of this Article 14, its rights, benefits and obligations hereunder, in whole or in part, (i) to Finnvera; (ii) subject to the written approval of Finnvera, after the
Availability Period; or (iii) subject to the written approval of Finnvera, to a parent or subsidiary corporation or an Affiliate of such Tranche B Lender.

| | 14.2.3. | Notwithstanding anything in this Article 14, a Tranche B Lender may not assign or transfer any of its rights, benefits and obligations
hereunder, in whole or in part, unless such Tranche B Lender also assigns and transfers, in its capacity as Tranche A Lender (as defined in the Credit Agreement) and concurrently therewith, the same portion of its rights, benefits and
obligations with respect to the Tranche A Loan to the same assignee.
| | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|14.3. | Transfer Agreement
|----- | ------------------

If a Tranche B Lender wishes to assign or transfer all or any of its rights, benefits and obligations hereunder in accordance with Section 14.2, then such assignment or transfer shall be
effected by the execution and delivery of a duly completed and executed Finnvera Transfer Agreement by such Tranche B Lender to the Finnvera Facility B Agent together with a transfer fee of Cdn.$3,500 (except where the Tranche B
Assignee is Finnvera, in which case no such transfer fee shall be payable), at least 5 Business Days prior to the effective date of such transfer, whereupon, to the extent that in such Finnvera Transfer Agreement such Tranche B Lender seeks to
assign or transfer its rights and obligations hereunder:



| | 14.3.1. | such Tranche B Lender shall be released from further obligations to the Borrower with respect to the portion of the obligations of such
Tranche B Lender assumed by the Tranche B Assignee under this Agreement;
| | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 23 -



---

| | 14.3.2. | the Tranche B Assignee shall assume the obligations of such Tranche B Lender under this Agreement and acquire the rights of such
Tranche B Lender in respect of the Borrower, without novation of the Borrowers obligations;
| | ------- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 14.3.3. | the Finnvera Facility B Agent, such Tranche B Lender and the Tranche B Assignee shall acquire the same rights and assume the same
obligations between themselves as they would have acquired and assumed had the Tranche B Assignee been an original party hereto with the obligations under this Agreement assumed and the rights acquired by it as a result of such assignment or
transfer; and
| | ------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 14.3.4. | the Borrower, the Finnvera Facility B Agent and such Tranche B Lender shall all execute such documents and perform such acts as may be
required to give effect to the transfer or assignment.
| | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|14.4. | Notice
|----- | ------

|14.5. | Sub-Participations
|----- | ------------------

A Tranche B Lender may, at its own cost, grant one or more sub-participations in its rights, benefits and obligations hereunder, provided that, notwithstanding any such sub-participation, such
Tranche B Lender shall remain, insofar as the Borrower and the Finnvera Facility B Agent are concerned, as the Tranche B Lender responsible hereunder, and the Borrower shall not be obliged to recognize any such sub-participant as
having the rights against it which it would have if it had been a party hereto.



|14.6. | General
|----- | -------

Notwithstanding anything contained in this Article:



| | 14.6.1. | The Finnvera Facility B Agent shall act as agent for each Tranche B Assignee and, in this connection, with respect to all decisions,
notices and other matters relating to anything referred to in this Agreement, the Borrower shall only be obliged to give notice to or request consents from the Finnvera Facility B Agent; and
| | ------- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 14.6.2. | the amounts payable by the Borrower under this Agreement shall not increase, whether in respect of withholding on account of taxes or otherwise, as
a result of any such assignment or transfer to a Tranche B Assignee which is a non-resident of Canada as defined in the Income Tax Act (Canada).
| | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|15. | SUBSIDIARY GUARANTEES
|--- | ---------------------



|15.1. | Guarantee
|----- | ---------

Subject to this Article 15, each of the Subsidiary Guarantors hereby unconditionally guarantees to the Security Agent for the ratable benefit of the Tranche B Lenders, and their respective
permitted successors and assigns (a) the due and punctual payment of all amounts due hereunder, in principal and interest, whether at maturity, by acceleration, or otherwise, and, to the extent permitted by law, the due and punctual performance
of all other liabilities and obligations of the Borrower hereunder (collectively, the Obligations), all in accordance with the terms hereof; and (b) in case of any extension of time of payment or renewal of the Finnvera
Facility B and the



- 24 -



---

Tranche B Advances made thereunder or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal,
whether at maturity, by acceleration pursuant to Section 12.2 hereof, or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Subsidiary Guarantors shall be jointly and
severally obligated to pay the same immediately. Each Subsidiary Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

Each Subsidiary Guarantor hereby agrees that its obligations with regard to its Subsidiary Guarantee shall be solidary (i.e. joint and several), unconditional, irrespective of the validity or
enforceability of the obligations of the Borrower under this Agreement, the absence of any action to enforce the same, the recovery of any judgment against the Borrower or any other obligor with respect to this Agreement or the Obligations, any
action to enforce the same or any other circumstances (other than complete performance) which might otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor. Each Subsidiary Guarantor further, to the extent permitted
by law, waives and relinquishes all claims, rights and remedies accorded by applicable law to guarantors and agrees not to assert or take advantage of any such claims, rights or remedies, including but not limited to: (a) any right to require
any of the Security Agent, the Finnvera Facility B Agent, the Tranche B Lenders or the Borrower (each a Benefited Party), as a condition of payment or performance by such Subsidiary Guarantor, to (1) proceed against
the Borrower, any other guarantor (including any other Subsidiary Guarantor) of the Obligations under the Subsidiary Guarantees or any other Person, (2) proceed against or exhaust any security held from the Borrower, any such other guarantor or
any other Person, (3) proceed against or have resort to any balance of any deposit account or credit on the books of any Benefited Party in favor of the Borrower or any other Person, or (4) pursue any other remedy in the power of any
Benefited Party whatsoever; (b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of the Borrower including any defense based on or arising out of the lack of validity or the unenforceability
of the Obligations under the Subsidiary Guarantees or any agreement or instrument relating thereto or by reason of the cessation of the liability of the Borrower from any cause other than payment in full of the Obligations under the Subsidiary
Guarantees; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (d) any defense based upon
any Benefited Partys errors or omissions in the administration of the Obligations under the Subsidiary Guarantees, except behavior which amounts to bad faith; (e)(1) any principles or provisions of law, statutory or otherwise, which are
or might be in conflict with the terms of the Subsidiary Guarantees and any legal or equitable discharge of such Subsidiary Guarantors obligations hereunder, (2) the benefit of any statute of limitations affecting such Subsidiary
Guarantors liability hereunder or the enforcement hereof, (3) any rights to set-offs, recoupments and counterclaims and (4) promptness, diligence and any requirement that any Benefited Party protect, secure, perfect or insure any
security interest or lien or any property subject thereto; (f) notices, demands, presentations, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance of the Subsidiary Guarantees, notices
of default under this Agreement or any agreement or instrument related thereto, notices of any renewal, extension or modification of the Obligations under the Subsidiary Guarantees or any agreement related thereto, and notices of any extension of
credit to the Borrower and any right to consent to any thereof; (g) to the extent permitted under applicable law, the benefits of any One Action rule and (h) any defenses or benefits that may be derived from or afforded by law
which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms of the Subsidiary Guarantees. Except to the extent expressly provided herein, each Subsidiary Guarantor hereby covenants that its Subsidiary
Guarantee shall not be discharged except by complete performance of the obligations contained in its Subsidiary Guarantee and this Agreement.



- 25 -



---

If any of the Security Agent, the Finnvera Facility B Agent or the Tranche
B Lenders is required by any court or otherwise to return to the Borrower, the Subsidiary Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Borrower or the Subsidiary Guarantors, any amount
paid either to the Security Agent, the Finnvera Facility B Agent or such Tranche B Lender, this Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

Each Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Security
Agent, the Finnvera Facility B Agent, the Tranche B Lenders or the Tranche A Lenders in respect of any obligations guaranteed hereby or in connection with the Tranche A Loan until payment in full of all obligations guaranteed hereby or thereby. Each
Subsidiary Guarantor further agrees that, as between the Subsidiary Guarantors, on the one hand, and the Security Agent, the Finnvera Facility B Agent and the Tranche B Lenders, on the other hand, (x) the maturity of the obligations guaranteed
hereby may be accelerated as provided in Section 12.2 hereof for the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby and
(y) in the event of any declaration of acceleration of such obligations as provided in Section 12.2 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantors for the purpose of
this Subsidiary Guarantee. The Subsidiary Guarantors shall have the right to seek contribution from any non-paying Subsidiary Guarantor so long as the exercise of such right does not impair the rights of the Security Agent, the Finnvera Facility B
Agent or the Tranche B Lenders.



|15.2. | Limitation on Subsidiary Guarantor Liability
|----- | --------------------------------------------

Each Subsidiary Guarantor, the Security Agent and each Tranche B Lender hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Subsidiary
Guarantor not constitute a fraudulent transfer or conveyance for the purposes of any federal or provincial law relating to bankruptcy or insolvency to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing intention, the
Security Agent, the Tranche B Lenders and the Subsidiary Guarantors hereby irrevocably agree that the obligations of such Subsidiary Guarantor under this Article 15 shall be limited to the maximum amount as shall, after giving effect to such maximum
amount and all other contingent and fixed liabilities of such Subsidiary Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other
Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under this Article 15, result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance.
In addition, the liability of each Subsidiary Guarantor governed by the Companies Act (Quebec) under its Subsidiary Guarantee shall be limited to the maximum amount permitted under Section 123.66 of the Companies Act (Quebec). To
that end, but only to the extent such obligations would otherwise be avoidable, the obligations of the Subsidiary Guarantor under this Article 15 shall be limited to the maximum amount that, after giving effect to the incurrence thereof, would not
render the Subsidiary Guarantor insolvent or unable to pay its debts as they mature.



- 26 -



---

|15.3. | Subsidiary Guarantors May Consolidate, etc., on Certain Terms
|----- | -------------------------------------------------------------

No Subsidiary Guarantor may consolidate, merge or amalgamate with or into (whether or not such Subsidiary Guarantor is the
surviving corporation) another Person whether or not affiliated with such Subsidiary Guarantor unless:



| | 15.3.1. | the Person formed by or surviving any such consolidation, merger or amalgamation (if other than a Subsidiary Guarantor or the Borrower)
unconditionally assumes all the obligations of such Subsidiary Guarantor under this Agreement and the Subsidiary Guarantee pursuant to a supplemental agreement in form and substance reasonably satisfactory to the Security Agent; and
| | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 15.3.2. | the Subsidiary Guarantor or the successor or surviving corporation, as applicable, complies with the requirements of Article 5 of the Trust
Indenture.
| | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------

In case of any such consolidation, merger, amalgamation, sale or conveyance and
upon the assumption by the successor Person, by supplemental agreement executed and delivered and satisfactory in form and substance to the Security Agent, of the Subsidiary Guarantee and the due and punctual performance of all of the covenants and
conditions of this Agreement to be performed by the Subsidiary Guarantor, such successor Person shall succeed to and be substituted for the Subsidiary Guarantor with the same effect as if it had been named herein as a Subsidiary Guarantor. All the
Subsidiary Guarantees so issued shall in all respects have the same legal rank and benefit under this Agreement as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this Agreement as though all of such

extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other

|17. | THE FINNVERA FACILITY B AGENT AND THE TRANCHE B LENDERS
|--- | -------------------------------------------------------



|17.1. | Authorization of Finnvera Facility B Agent
|----- | ------------------------------------------

Each Tranche B Lender hereby irrevocably appoints and authorizes the Finnvera Facility B Agent to act for all purposes as its agent hereunder (including, without limitation, its role
as guarantee holder of the ECA Guarantee for and on behalf of the Tranche B Lenders pursuant to the ECA Guarantee) with such powers as are expressly delegated to the Finnvera Facility B Agent by the terms of this Agreement and/or the ECA Guarantee,
together with such other powers as are reasonably incidental thereto and undertakes not to take any action on its own. Notwithstanding the provisions of the Civil Code of Quebec relating to contracts generally and to mandate, the Finnvera
Facility B Agent shall have no duties or responsibilities except those expressly set forth in this Agreement. As to any matters not expressly provided for by this Agreement, the Finnvera Facility B Agent shall act hereunder or in connection herewith
in accordance with the instructions of the Tranche B Lenders in accordance with the provisions of this Article 17, but, in the absence of any such instructions, the Finnvera Facility B Agent may (but shall not be obliged to) act as it shall deem fit
in the best interests of the Tranche B Lenders, and any such instructions and any action taken by the Finnvera Facility B Agent in accordance herewith shall be binding upon each Tranche B Lender. The Finnvera Facility B Agent shall not, by reason of
this Agreement and/or the ECA Guarantee, be deemed to be a trustee for the benefit of any Tranche B Lender, the Borrower or any other Person and the Finnvera Facility B Agents duties under this Agreement and/or the ECA Guarantee are solely
mechanical and administrative in nature. Neither the Finnvera Facility B Agent nor any of its directors, officers, employees or agents shall be responsible to the Tranche B Lenders for any recitals, statements, representations or warranties
contained in this Agreement or in any certificate or other document referred to, or provided for in (including, without limitation, the ECA Guarantee), or received by any of them under, this Agreement and/or the ECA Guarantee, for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement, or any other document referred to or provided for herein (including, without limitation, the ECA Guarantee) or any collateral provided for hereby or for any
failure by the Borrower to perform its obligations hereunder. The Finnvera Facility B Agent may employ agents and attorneys-in-fact to assist the Finnvera Facility B Agent and shall not be responsible for the negligence or misconduct of any such
agents or attorneys-in-fact selected by it with reasonable care. Neither the Finnvera Facility B Agent nor any of its directors, officers, employees or agents shall be responsible for any action taken or omitted to be taken by it or them under or in
connection herewith (including, without limitation, the ECA Guarantee), except for its or their own gross negligence or wilful misconduct.



|17.2. | Finnvera Facility B Agents Responsibility
|----- | ------------------------------------------



| | 17.2.1. | The Finnvera Facility B Agent shall be entitled to rely upon any certificate, notice or other document (including any cable, telegram, telex or
facsimile) believed by it to be genuine and correct and to have been signed or sent by or on behalf of the proper person or persons, and upon advice and statements of legal advisers, independent accountants and other experts selected by the Finnvera
Facility B Agent. The Finnvera Facility B Agent may deem and treat each Tranche B Lender as the holder of the Tranche B Commitment in the Tranche B Loan made by such Tranche B Lender for all purposes hereof unless and until a Tranche B Assignment
has been completed in accordance with Section 14.2.
| | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 17.2.2. | The Finnvera Facility B Agent shall not be deemed to have knowledge of the occurrence of a Default or Event of Default unless the Finnvera Facility
B Agent has
| | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



- 31 -



---

| | received notice from a Tranche B Lender or the Borrower describing such a Default or Event of Default and stating that such notice is a Notice of Default. In the event that the
Finnvera Facility B Agent receives such a notice of the occurrence of a Default or Event of Default or otherwise becomes aware that a Default or Event of Default has occurred, the Finnvera Facility B Agent shall promptly give notice thereof to the
Tranche B Lenders. The Finnvera Facility B Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Tranche B Lenders in accordance with the provisions of this Article 17 provided that,
unless and until the Finnvera Facility B Agent shall have received such directions, the Finnvera Facility B Agent may (but shall not be obliged to) take such action, or refrain from taking such action, with respect to such a Default or Event of
Default as it shall deem advisable in the best interest of the Tranche B Lenders.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 17.2.3. | The Finnvera Facility B Agent shall have no responsibility, (a) to the Borrower on account of the failure of any Tranche B Lender to perform
its obligations hereunder, or (b) to any Tranche B Lender on account of the failure of (i) the Borrower to perform its obligations hereunder or (ii) Finnvera to perform its obligations under the ECA Guarantee.
| | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 17.2.4. | Each Tranche B Lender severally represents and warrants to the Finnvera Facility B Agent that it has made its own independent investigation of the
financial condition and affairs of the Borrower in connection with the making and continuation of its Tranche B Commitment in the Tranche B Loan hereunder and has not relied on any information provided to such Tranche B Lender by the Finnvera
Facility B Agent in connection herewith (including, without limitation, the ECA Guarantee), and each Tranche B Lender represents and warrants to the Finnvera Facility B Agent that it shall continue to make its own independent appraisal of the
creditworthiness of the Borrower while the Tranche B Loan is outstanding or the Tranche B Lenders have any obligations hereunder.
| | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|17.3. | Rights of Finnvera Facility B Agent as Tranche B Lender
|----- | -------------------------------------------------------

With respect to its Tranche B Commitment in the Tranche B Loan, the Finnvera Facility B Agent in its capacity as a Tranche B
Lender shall have the same rights and powers hereunder as any other Tranche B Lender and may exercise the same as though it were not acting as the Finnvera Facility B Agent and the term Tranche B Lender shall, unless the context
otherwise indicates, include the Finnvera Facility B Agent in its capacity as a Tranche B Lender. The Finnvera Facility B Agent may (without having to account therefor to any Tranche B Lender) accept deposits from, lend money to and generally engage
in any kind of banking or other business with the Borrower as if it were not acting as the Finnvera Facility B Agent and may accept fees and other consideration from the Borrower for customary services in connection with this Agreement and the
Tranche B Loan and otherwise without having to account for the same to the Tranche B Lenders.



|17.4. | Indemnity
|----- | ---------

Each Tranche B Lender agrees to indemnify the Finnvera Facility B Agent, to the extent not otherwise reimbursed by the Borrower, rateably in accordance with its respective Tranche B Commitments, for any
and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against, the Finnvera Facility B Agent in
any way relating



- 32 -



---

to or arising out of this Agreement or any other documents contemplated by or referred to herein (including, without limitation, the ECA Guarantee) or therein or the transactions contemplated
hereby or thereby (excluding, unless a Default or Event of Default is apprehended or has occurred and is continuing, normal administrative costs and expenses incidental to the performance of its agency duties hereunder) or the enforcement of any of
the terms hereof or of any such other documents (including, without limitation, the ECA Guarantee), provided that no Tranche B Lender shall be liable for any of the foregoing to the extent they arise from the Finnvera Facility B Agents gross
negligence or wilful misconduct.



|17.5. | Notice by Finnvera Facility B Agent to Tranche B Lenders
|----- | --------------------------------------------------------

As soon as practicable after its receipt thereof, the Finnvera Facility B Agent will forward to each Tranche B Lender a copy
of each report, notice or other document required by this Agreement to be delivered to the Finnvera Facility B Agent for such Tranche B Lender.



|17.6. | Protection of Finnvera Facility B Agent
|----- | ---------------------------------------



| | 17.6.1. | The Finnvera Facility B Agent shall not be required to keep itself informed as to the performance or observance by the Borrower of this Agreement or
any other document referred to or provided for herein or therein or to inspect the properties or books of the Borrower. Except (in the case of the Finnvera Facility B Agent) for notices, reports and other documents and information expressly required
to be furnished to the Tranche B Lenders by the Finnvera Facility B Agent hereunder, the Finnvera Facility B Agent shall have no duty or responsibility to provide any Tranche B Lender with any credit or other information concerning the affairs or
financial condition of the Borrower which may come to the attention of the Finnvera Facility B Agent, except where provided to the Finnvera Facility B Agent for the Tranche B Lenders, provided that such information does not confer any advantage to
the Finnvera Facility B Agent as a Tranche B Lender over the other Tranche B Lenders. Nothing in this Agreement shall oblige the Finnvera Facility B Agent to disclose any information relating to the Borrower if such disclosure would or might, in the
opinion of the Finnvera Facility B Agent, constitute a breach of any Laws or duty of secrecy or confidence.
| | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 17.6.2. | Unless the Finnvera Facility B Agent shall have been notified in writing or by telegraph, telex or facsimile by any Tranche B Lender, prior to the
date of a Tranche B Advance requested hereunder or the Tranche B Rollover Date, that such Tranche B Lender does not intend to make available to the Finnvera Facility B Agent such Tranche B Lenders proportionate share of such Tranche B Advance,
based on its Tranche B Commitment, the Finnvera Facility B Agent may assume that such Tranche B Lender has made such Tranche B Lenders Tranche B Commitment in such Tranche B Advance available to the Finnvera Facility B Agent on the date of
such Tranche B Advance and the Finnvera Facility B Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Finnvera Facility B Agent by
such Tranche B Lender, the Finnvera Facility B Agent shall be entitled to recover such amount (together with interest thereon at the rate determined by the Finnvera Facility B Agent as being its cost of funds in the circumstances) on demand from
such Tranche B Lender or, if such Tranche B Lender fails to reimburse the Finnvera Facility B Agent for such amount on demand, from the Borrower.
| | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 33 -



---

| | 17.6.3. | Unless the Finnvera Facility B Agent shall have been notified in writing or by telegraph, telex or facsimile by the Borrower, prior to the date on
which any payment is due hereunder, that the Borrower does not intend to make such payment, the Finnvera Facility B Agent may assume that the Borrower has made such payment when due and the Finnvera Facility B Agent may, in reliance upon such
assumption, make available to each Tranche B Lender on such payment date an amount equal to such Tranche B Lenders pro rata share of such assumed payment. If it is established that the Borrower has not in fact made such payment to the
Finnvera Facility B Agent, each Tranche B Lender shall forthwith on demand repay to the Finnvera Facility B Agent the amount made available to such Tranche B Lender (together with interest at the rate determined by the Finnvera Facility B Agent as
being its cost of funds in the circumstances).
| | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|17.7. | Notice by Tranche B Lenders to Finnvera Facility B Agent
|----- | --------------------------------------------------------

Each Tranche B Lender shall endeavour to use its best efforts to notify the Finnvera Facility B Agent of the occurrence of
any Default or Event of Default forthwith upon becoming aware of such event, but no Tranche B Lender shall be liable if it fails to give such notice to the Finnvera Facility B Agent.



|17.8. | Sharing Among the Tranche B Lenders
|----- | -----------------------------------

Each Tranche B Lender agrees that as amongst themselves, except as otherwise provided for by the provisions of this Agreement, all amounts received by the Finnvera Facility B Agent,
in its capacity as agent of the Tranche B Lenders, pursuant to this Agreement or any other document contemplated hereby (including, without limitation, in its role as guarantee holder for and on behalf of the Tranche B Lenders pursuant to the ECA
Guarantee) (whether received by voluntary payment, by the exercise of the right of set-off or compensation or by counterclaim, cross-claim or separate action, other than agency fees), and all amounts received by any Tranche B Lender in relation to
this Agreement (including, without limitation, the ECA Guarantee) shall be shared by each Tranche B Lender pro rata, in accordance with their respective Tranche B Commitment and each Tranche B Lender undertakes to do all such things as may be
reasonably required to give full effect to this Section 17.8. If any amount which is so shared is later recovered from the Tranche B Lender who originally received it, each other Tranche B Lender shall restore its proportionate share of such amount
to such Tranche B Lender, without interest. The Finnvera Facility B Agent shall not be bound to account to any Tranche B Lender for any sum or the profit element of any sum received by it for its own account.

As a necessary consequence of the foregoing, each Tranche B Lender shall share, in a percentage equal to its Tranche B
Commitment, any losses incurred as a result of any Default or Event of Default by the Borrower, and shall pay to the Finnvera Facility B Agent, within two (2) Business Days following a request by the Finnvera Facility B Agent, any amount
required to ensure that such Tranche B Lender bears its pro rata share of such losses, if any. Such obligation to share losses shall be absolute and unconditional and shall not be affected by any circumstance, including, without limitation,
(1) any set-off, compensation, counterclaim, recoupment, defence or other right which such Tranche B Lender may have against the Finnvera Facility B Agent, the Borrower or any other Person for any reason whatsoever; (2) the occurrence or
continuance of any Default or Event of Default; (3) any adverse change in the condition (financial or otherwise) of the Borrower or any other Person; (4) any breach of this Agreement by the Borrower or any other Person; or (5) any
other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. If any Tranche B Lender does not make available the amount required hereunder, the Finnvera Facility B Agent shall be entitled to recover such amount
on demand from



- 34 -



---

such Tranche B Lender, together with interest thereon (at the rate determined by the Finnvera Facility B Agent as being its cost of funds in the circumstances) from the date of non-payment until
such amount is paid in full.



|17.9. | Procedure with respect to Tranche B Advances
|----- | --------------------------------------------

Subject to the provisions of this Agreement, upon receipt of a Tranche B Notice of Borrowing or a Notice of New Tranche B Designated Period from the Borrower and no later than three
(3) Business Days prior to the date of the proposed Tranche B Advance or the Tranche B Rollover Date, the Finnvera Facility B Agent shall, without delay, advise each Tranche B Lender of the receipt of such notice, of the date of such Tranche B
Advance or the Tranche B Rollover Date, of its proportionate share of the amount of each Tranche B Advance or continuation thereof and of the relevant details of the Finnvera Facility B Agents account(s). Each Tranche B Lender shall disburse
its proportionate share of each Tranche B Advance, taking into account its Tranche B Commitment, and shall make it available to the Finnvera Facility B Agent on the date of the Tranche B Advance fixed by the Borrower, by depositing its proportionate
share of the Tranche B Advance in the Finnvera Facility B Agents account in Canadian Dollars or US Dollars, as the case may be. Once the Borrower has fulfilled the conditions stipulated in this Agreement, the Finnvera Facility B Agent will
make such amounts available to the Borrower on the date of the Tranche B Advance, at the Finnvera Facility Agency Branch, and, in the absence of other arrangements made in writing between the Finnvera Facility B Agent and the Borrower, by
transferring or causing to be transferred an equivalent amount, in accordance with the instructions of the Borrower which appear in the Tranche B Notice of Borrowing with respect to each Tranche B Advance; however, the obligation of the Finnvera
Facility B Agent with respect hereto is limited to taking the steps judged commercially reasonable in order to follow such instructions, and once undertaken, such steps shall constitute conclusive evidence that the amounts have been disbursed in
accordance with the applicable provisions. The Finnvera Facility B Agent shall not be liable for damages, claims or costs imputed to the Borrower and resulting from the fact that the amount of a Tranche B Advance did not arrive at its agreed-upon
destination.



|17.10. | Accounts kept by each Tranche B Lender
|------ | --------------------------------------

Each Tranche B Lender shall keep in its books, in respect of its Tranche B Commitment, accounts for the Tranche B CDOR Advances and Tranche B LIBOR Advances (as the case may be) and
other amounts payable by the Borrower to such Tranche B Lender under this Agreement. Each Tranche B Lender shall make appropriate entries showing, as debits, the amount of the debt of the Borrower to it in respect of the Tranche B CDOR Advances and
Tranche B LIBOR Advances (as the case may be) the amount of all accrued interest and any other amount due to such Tranche B Lender pursuant hereto and, as credits, each payment or repayment of principal and interest made in respect of such
indebtedness as well as any other amount paid to such Tranche B Lender pursuant hereto. These accounts shall constitute (in the absence of manifest error or of contradictory entries in the accounts of the Finnvera Facility B Agent referred to in
Section 4.5) prima facie evidence of their content against the Borrower.

The accounts which are
maintained by the Finnvera Facility B Agent shall constitute, except in the case of manifest error, prima facie proof of the amounts advanced by the Tranche B Lenders, the interest and other amounts due to them and the payments of principal,
interest or others made to the Tranche B Lenders.



- 35 -



---

|17.11. | Binding Determinations
|------ | ----------------------

The Finnvera Facility B Agent shall proceed in good faith to make any determination which is required in order to apply this Agreement and, once made, such determination shall be final and binding upon
all parties, except in the case of manifest error.



|17.12. | Amendment of Article 17
|------ | -----------------------

The provisions of this Article 17 relating to the rights and obligations of the Tranche B Lenders and the Finnvera Facility B Agent inter se may not be amended or added to, at any time or from time
to time, without the consent and agreement of the Finnvera Facility B Agent and the Tranche B Lenders by way of an instrument in writing, which instrument in writing shall validly and effectively amend or add to any or all of the provisions of this
Article affecting the Tranche B Lenders without requiring the execution of such instrument in writing by the Borrower.



|17.13. | Decisions, Amendments and Waivers of the Tranche B Lenders
|------ | ----------------------------------------------------------

When the Tranche B Lenders may or must consent to an action or to anything or to accomplish another act in applying this
Agreement, the Finnvera Facility B Agent shall request that each Tranche B Lender give its consent in this regard. Subject to the provisions of Section 17.14, all decisions taken by the Tranche B Lenders shall be taken as follows: a) if there are
two Tranche B Lenders, by unanimous consent; b) if there are three or more Tranche B Lenders, by the Majority Tranche B Lenders. The Finnvera Facility B Agent shall confirm such consent to each Tranche B Lender and to the Borrower.



|17.14. | Authorized Waivers, Variations and Omissions
|------ | --------------------------------------------

|17.16. | Resignation of the Finnvera Facility B Agent
|------ | --------------------------------------------



| | 17.16.1. | Notwithstanding the irrevocable appointment of the Finnvera Facility B Agent, the Majority Tranche B Lenders and the Majority Tranche A Lenders (as
defined in the Credit Agreement) may collectively (with the consent of the Borrower), upon giving the Finnvera Facility B Agent thirty (30) days prior written notice to such effect, terminate the Finnvera Facility B Agents appointment
hereunder provided that a successor Finnvera Facility B Agent has been appointed at or prior to the expiry of such notice.

| | 17.16.2. | The Finnvera Facility B Agent may resign its appointment hereunder at any time without giving any reason therefor by giving written notice to such
effect to each of the other parties hereto. Such resignation shall not be effective until a successor Finnvera Facility B Agent has been appointed.
| | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 17.16.3. | In the event of any such notice of termination or resignation, the Majority Tranche B Lenders and the Majority Tranche A Lenders (as defined in the
Credit Agreement) shall collectively appoint a successor Finnvera Facility B Agent that is willing to accept such role and is acceptable to the Borrower within thirty (30) days therefrom, deliver copies of all accounts to such successor and the
retiring Finnvera Facility B Agent shall be discharged from any further obligations hereunder but shall remain entitled to the benefit of the provisions of this Article 17 and the Finnvera Facility B Agents successor and each of the other
parties hereto shall have the same rights and obligations among themselves as they would have had if such successor originally had been a party hereto as Finnvera Facility B Agent. If the Majority Tranche B Lenders and the Majority Tranche A Lenders
have not collectively appointed a successor Finnvera Facility B Agent within thirty (30) days of the delivery of any notice of termination or resignation as set forth above, the Finnvera Facility B Agent (with the consent of the Borrower, which
consent shall not be unreasonably withheld or delayed) may appoint a successor Finnvera Facility B Agent.

agreement containing provisions substantially the same as those of this Article, to (x)any Tranche B Assignee or participant in, or any prospective Tranche B Assignee of or
participant in, any of its rights or obligations under this Agreement and (y)any actual or prospective counterparty (or its advisors) to any swap, hedge, derivative, credit-linked note or similar transaction relating to the Borrower and
its obligations; (g) to any Person with the consent of the Borrower; (h) to any Person to the extent such Information (x)is or becomes publicly available other than as a result of a breach of this Article or
(y)becomes available to the Finnvera Facility B Agent or any Tranche B Lender on a non-confidential basis from a source other than the Borrower and provided such source has not, to the knowledge of the Finnvera Facility B Agent or such
Tranche B Lender, breached a duty of confidentiality owed to the Borrower, the Finnvera Facility B Agent or the Tranche B Lenders; (i) to Finnvera; or (j) to NSN, to the extent necessary in the reasonable opinion of the Finnvera Facility B
Agent and only in respect of the mechanics of the disbursement of Tranche B Advances. For purposes of this Article, Information means all information relating to the Borrower or any of its Affiliates or any of their respective
businesses including all information relating to the transactions contemplated by this Agreement, other than any such information that is available to the Finnvera Facility B Agent or any Tranche B Lender on a non-confidential basis prior to such
receipt. Any Person required to maintain the confidentiality of Information as provided in this Article shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own confidential information. In addition, the Finnvera Facility B Agent may disclose to any agency or organization that assigns standard identification numbers to loan
facilities such basic information describing the facilities provided hereunder as is necessary to assign unique identifiers (and, if requested, supply a copy of this Agreement), it being understood that the Person to whom such disclosure is made
will be informed of the confidential nature of such Information and instructed to make available to the public only such Information as such person normally makes available in the course of its business of assigning identification numbers. In
addition, and notwithstanding anything in this Agreement to the contrary, the Finnvera Facility B Agent and the Tranche B Lenders may disclose the existence of the credit facilities established under this Agreement and non-sensitive information
relating to same to Finnvera (who may publish same on their website), market data collectors, recognized trade publishers and similar service providers for general circulation in the loan market and/or for general advertising purposes.

WHEREAS the obligation of the Tranche B Lenders to continue to make the Finnvera Facility B available to the Borrower is conditioned upon, among other things, the execution and delivery of this
Subsidiary Guarantee by the Subsidiary Guarantor;

WHEREAS the Subsidiary Guarantor is willing to and it is in the best
interest of the Subsidiary Guarantor to execute and deliver this Subsidiary Guarantee ;

NOW, THEREFORE, in
consideration of the Tranche B Lenders having entered into the Finnvera Facility B Credit Agreement with the Borrower and having agreed, subject to the terms and conditions therein provided, to make the Finnvera Facility B available to the Borrower,
the parties hereto have agreed as follows:

|1.2. | Definitions

document or instrument supplemental or ancillary hereto, shall have the meanings ascribed thereto in the Finnvera Facility B Credit Agreement.

|1.3. | Headings

The division of this Subsidiary Guarantee into articles, sections, subsections, paragraphs and subparagraphs and the insertion of titles is for convenience of reference only and does not affect the

|2. | SUBSIDIARY GUARANTEE
|-- | --------------------



|2.1. | Guarantee
|---- | ---------

The Subsidiary Guarantor hereby unconditionally guarantees to the Security Agent for the ratable benefit of the Tranche B Lenders, and their respective permitted successors and assigns (a) the due
and punctual payment of all amounts due under the Finnvera Facility B Credit Agreement, in principal and interest, whether at maturity, by acceleration, or otherwise, and, to the extent permitted by law, the due and punctual performance of all other
liabilities and obligations of the Borrower thereunder (collectively, the Obligations), all in accordance with the terms hereof; and (b) in case of any extension of time of payment or renewal of the Finnvera Facility B and
the Tranche B Advances made thereunder or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at maturity, by acceleration pursuant to
Section 12.2 of the Finnvera Facility B Credit Agreement, or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Subsidiary Guarantor shall be jointly and severally obligated
with the other Subsidiary Guarantors to pay the same immediately. The Subsidiary Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. The Subsidiary Guarantor hereby agrees that its obligations with regard to its
Subsidiary Guarantee shall be solidary (i.e. joint and several), unconditional, irrespective of the validity or enforceability of the obligations of the Borrower under the Finnvera Facility B Credit Agreement, the absence of any action to enforce
the same, the recovery of any judgment against the Borrower or any other obligor with respect to Finnvera Facility B Credit Agreement or the Obligations, any action to enforce the same or any other circumstances (other than complete performance)
which might otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor. The Subsidiary Guarantor further, to the extent permitted by law, waives and relinquishes all claims, rights and remedies accorded by applicable
law to guarantors and agrees not to assert or take advantage of any such claims, rights or remedies, including but not limited to (a) any right to require any of the Security Agent, the Finnvera Facility B Agent, the Tranche B Lenders or the
Borrower (each a Benefited Party), as a condition of payment or performance by the Subsidiary Guarantor, to (1) proceed against the Borrower, any other guarantor (including any other



---

Subsidiary Guarantor) of the Obligations under the Subsidiary Guarantees or any other Person; (2) proceed against or exhaust any security held from the Borrower, any such other guarantor or
any other Person; (3) proceed against or have resort to any balance of any deposit account or credit on the books of any Benefited Party in favor of the Borrower or any other Person; or (4) pursue any other remedy in the power of any
Benefited Party whatsoever; (b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of the Borrower including any defense based on or arising out of the lack of validity or the unenforceability
of the Obligations under the Subsidiary Guarantees or any agreement or instrument relating thereto or by reason of the cessation of the liability of the Borrower from any cause other than payment in full of the Obligations under the Subsidiary
Guarantees; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (d) any defense based upon
any Benefited Partys errors or omissions in the administration of the Obligations under the Subsidiary Guarantees, except behavior which amounts to bad faith; (e) (1) any principles or provisions of law, statutory or otherwise, which
are or might be in conflict with the terms of the Subsidiary Guarantees and any legal or equitable discharge of the Subsidiary Guarantors obligations hereunder; (2) the benefit of any statute of limitations affecting the Subsidiary
Guarantors liability hereunder or the enforcement hereof; (3) any rights to set offs, recoupments and counterclaims; and (4) promptness, diligence and any requirement that any Benefited Party protect, secure, perfect or insure any
security interest or lien or any property subject thereto; (f) notices, demands, presentations, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance of the Subsidiary Guarantees, notices
of default under the Finnvera Facility B Credit Agreement or any agreement or instrument related thereto, notices of any renewal, extension or modification of the Obligations under the Subsidiary Guarantees or any agreement related thereto, and
notices of any extension of credit to the Borrower and any right to consent to any thereof; (g) to the extent permitted under applicable law, the benefits of any One Action rule; and (h) any defenses or benefits that may be
derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms of the Subsidiary Guarantees. Except to the extent expressly provided herein, the Subsidiary Guarantor hereby
covenants that its Subsidiary Guarantee shall not be discharged except by complete performance of the obligations contained herein and in the Finnvera Facility B Credit Agreement.

If any of the Security Agent, the Finnvera Facility B Agent or the Tranche B Lenders is required by any court or otherwise
to return to the Borrower, the Subsidiary Guarantors, or any custodian, trustee, liquidator or other similar official acting in relation to either the Borrower or the Subsidiary Guarantors, any amount paid either to the Security Agent, the Finnvera
Facility B Agent or such Tranche B Lender, this Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

The Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Security Agent, the Finnvera Facility B Agent, the Tranche B Lenders or the Tranche A Lenders
in respect of any obligations guaranteed hereby or in connection with the Tranche A Loan until payment in full of all obligations guaranteed hereby or thereby.



---

The Subsidiary Guarantor further agrees that, as between the Subsidiary
Guarantors, on the one hand, and the Security Agent, the Finnvera Facility B Agent and the Tranche B Lenders, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Section 12.2 of the
Finnvera Facility B Credit Agreement for the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby and (y) in the event of
any declaration of acceleration of such obligations as provided in Section 12.2 of the Finnvera Facility B Credit Agreement, such obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantor
for the purpose of this Subsidiary Guarantee. The Subsidiary Guarantor shall have the right to seek contribution from any non paying Subsidiary Guarantor so long as the exercise of such right does not impair the rights of the Security Agent, the
Finnvera Facility B Agent or the Tranche B Lenders.



|2.2. | Limitation on Subsidiary Guarantor Liability
|---- | --------------------------------------------

The Subsidiary Guarantor and the Security Agent and each Tranche B Lender hereby confirms that it is the intention of all such parties that this Subsidiary Guarantee not constitute a
fraudulent transfer or conveyance for the purposes of any federal or provincial law relating to bankruptcy or insolvency to the extent applicable to this Subsidiary Guarantee. To effectuate the foregoing intention, the Security Agent, the Tranche B
Lenders and the Subsidiary Guarantor hereby irrevocably agree that the obligations of the Subsidiary Guarantor under this Subsidiary Guarantee shall be limited to the maximum amount as shall, after giving effect to such maximum amount and all other
contingent and fixed liabilities of the Subsidiary Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Subsidiary Guarantor
in respect of the obligations of such other Subsidiary Guarantor under Article 15 of the Finnvera Facility B Credit Agreement or under any other Subsidiary Guarantee, as applicable, result in the obligations of the Subsidiary Guarantor hereunder not
constituting a fraudulent transfer or conveyance. [In addition, the liability of the Subsidiary Guarantor governed by theCompanies Act(Quebec) under this Subsidiary Guarantee shall be limited to the maximum amount permitted
under Section 123.66 of theCompanies Act(Quebec). To that end, but only to the extent such obligations would otherwise be avoidable, the obligations of the Subsidiary Guarantor under this Subsidiary Guarantee shall be
limited to the maximum amount that, after giving effect to the incurrence thereof, would not render the Subsidiary Guarantor insolvent or unable to pay its debts as they mature.]



|2.3. | Subsidiary Guarantor May Consolidate, etc., on Certain Terms
|---- | ------------------------------------------------------------

The Subsidiary Guarantor may not consolidate, merge or amalgamate with or into (whether or not the Subsidiary Guarantor is
the surviving corporation) another Person whether or not affiliated with the Subsidiary Guarantor unless:



| | 2.3.1. | the Person formed by or surviving any such consolidation, merger or amalgamation (if other than the Subsidiary Guarantor, any other Subsidiary
Guarantor or the Borrower) unconditionally assumes all the obligations of the Subsidiary Guarantor under the Finnvera Facility B Credit Agreement and this Subsidiary Guarantee pursuant to a supplemental agreement in form and substance reasonably
satisfactory to the Security Agent; and
| | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | 2.3.2. | the Subsidiary Guarantor or the successor or surviving corporation, as applicable, complies with the requirements of Article 5 of the Trust
Indenture.
| | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------

In case of any such consolidation, merger, amalgamation, sale or conveyance and
upon the assumption by the successor Person, by supplemental agreement executed and delivered and satisfactory in form and substance to the Security Agent, of a Subsidiary Guarantee and the due and punctual performance of all of the covenants and
conditions of the Finnvera Facility B Credit Agreement to be performed by the Subsidiary Guarantor, such successor Person shall succeed to and be substituted for the Subsidiary Guarantor with the same effect as if it had been named herein as a
Subsidiary Guarantor. All the Subsidiary Guarantees so issued shall in all respects have the same legal rank and benefit under the Finnvera Facility B Credit Agreement as the Subsidiary Guarantees theretofore and thereafter issued in accordance
with the terms of the Finnvera Facility B Credit Agreement as though all of such Subsidiary Guarantees had been issued at the date of the execution of the Finnvera Facility B Credit Agreement.

Except as set forth in Articles 4 and 5 of the Trust Indenture and notwithstanding subsections 2.3.1 and 2.3.2
above, nothing contained in the Finnvera Facility B Credit Agreement shall prevent any consolidation, merger or amalgamation of a Subsidiary Guarantor with or into the Borrower or another Subsidiary Guarantor, or shall prevent any sale or
conveyance of the property of a Subsidiary Guarantor as an entirety or substantially as an entirety to the Borrower or another Subsidiary Guarantor.



|2.4. | Releases

| | 2.4.1. | In the event of a release of the Subsidiary Guarantor from its obligations under the guarantee it has provided in connection with the Trust
Indenture (the Trust Indenture Guarantee), the whole pursuant to and in accordance with the terms and conditions of Section 10.05 of the Trust Indenture, and upon delivery by the Subsidiary Guarantor to the Security Agent of
all documents executed by the Trustee (as defined in the Trust Indenture) evidencing such a release, the Subsidiary Guarantor shall be released and relieved of its obligations under this Subsidiary Guarantee and the Security Agent shall execute and
deliver any documents reasonably required in order to evidence the foregoing release.
| | ------ | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2.4.2. | All other releases of the Subsidiary Guarantor from its obligations under the Trust Indenture Guarantee not contemplated under Section 10.05 of
the Trust Indenture shall not operate as a release of the Subsidiary Guarantor from its obligations under this Subsidiary Guarantee without the prior written consent of the Tranche B Lenders.
