3.4 Interest on Arrears



|(a) | Any amount in principal which has not been paid on the Maturity Date and any other amount (in interest or otherwise) which is not paid when due will bear interest at the Prime Rate

Y is the portion of same that the Borrower elects to exclude from the prepayment (provided that the aggregate of all amounts so excluded must not exceed $ 1,000,000 per financial year), in each case as specified in the notice. For
greater certainty, the Borrower will have no obligation to give said notice in any instance where the result of X minus Y is not a positive amount (due to an election made by it pursuant to the previous sentence).
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

any payment due or made by the Borrower, the Borrower must pay to the Agent or such Lender such additional amount as may be necessary in order that the payment actually received be equal to the payment which otherwise would have been received in the
absence of such withholding or deduction or tax (including in the absence of any additional withholding or deduction or tax in

| | expenditures. Following any such withdrawal, the Borrower will deposit, within 45 days from the end of each subsequent financial quarter, all Free Cash Flow
(less any portion thereof required to be deposited for the relevant quarter in the Debt Service Account) until the credit balance in the Maintenance Account becomes equal to the Maintenance Requirement.

| | (c) | Following however the delivery of a stop notice pursuant to the terms and conditions of the Depositary Agreement, the Borrower will only be entitled to require withdrawals from the
Maintenance Account to fund maintenance capital expenditures acceptable to the Agent; such withdrawals will then be subject to the Agents consent further to its review of the Borrowers request detailing the maintenance capital
expenditures to be funded with such withdrawal. The Agent will be entitled to give a stop notice only if a Default has occurred and is continuing.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

5.3 Debt Service Account



| | (a) | The Borrower will establish with the Depositary an account entitled Debt Service Reserve Account (the Debt Service Account) and enter into with the
Agent and the Depositary Agreement concerning such account. The Borrower will cause to be deposited in the Debt Service Account on the Business Day following the closing of the Transaction an amount sufficient to meet the Debt Service Reserve
Requirement. Thereafter, if at the end of any financial quarter of the Borrower, the credit balance in the Debt Service Account is less than the Debt Service Reserve Requirement, the Borrower will deposit, within 45 days from the end of such
financial quarter, all Free Cash Flow for such quarter until the credit balance in the Debt Service Account becomes equal to the Debt Service Reserve Requirement.

| | (b) | The Borrower may make withdrawals from the Debt Service Account if it does not expect that the Excess Cash Flow for the financial quarter of the withdrawal (calculated for such
purposes only without deducting Interest Expense) will be sufficient to make the next interest payment on the Loan.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Provided that no Default has occurred and is continuing and to the extent that from time to time the credit balance in the Debt Service Account exceeds the then applicable Debt
Service Reserve Requirement, the Borrower may also withdraw the amount of such excess. For greater certainty, no withdrawal will be made if a Default has occurred and is continuing.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | Following however the delivery of a stop notice pursuant to the terms and conditions of the Depositary Agreement, the Borrower will no longer be entitled to make withdrawals from
the Debt Service Account and the Agent will be entitled to debit the Debt Service Account and to apply the amounts so debited to indebtedness owing under the Credit Documents.

15.8 Liability of Lenders

Each Lender acknowledges that it has been and will continue to be solely responsible for making its own independent appraisal and investigation of the financial condition of the Borrower and any other Credit Party,

such information as such person normally makes available in the course of its business of assigning identification numbers. In addition, the Agent may provide to Loan Pricing Corporation or other recognized publishers of information for circulation
in the loan market information of the type customarily provided by financial institutions to Loan Pricing Corporation.

17 - MISCELLANEOUS

17.1 Books and Accounts

The Agent will keep
books and accounts evidencing the transactions made pursuant to this Agreement. Absent manifest error, such books and accounts will be deemed to represent accurately such transactions and the indebtedness of the Borrower under the Loan.

17.2 Determination

In the absence of
manifest error, any determination made by the Agent of the amounts payable hereunder will be conclusive and binding upon the Lenders and the Borrower.

17.3 Prohibition on Assignment by Borrower

The Borrower may not assign its rights, or the amounts to be received by
it, under this Agreement.

17.4 Assignments and Participations



|(a) | A Lender (the Assignor) may assign, in whole or in part, its Commitment (including outstanding advances owing to it) to any Person who makes, purchases or otherwise
invests in commercial loans in the course of its business (the Assignee). The assignment must be made in an instrument substantially in the form of Schedule C. The Assignor must pay to the Agent, for its own account, an
assignment fee of $3,500. When the assignment becomes effective, the Assignee will become a Lender and will benefit from the rights and be liable for the obligations of the Assignor, proportionally to the assigned Commitment, and, to the same
extent, the Assignor will be released from its obligations. The Assignor and the Assignee will be liable for all expenses incurred by the Agent in connection with such assignment.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(b) | Except if made in favour of an Affiliate of the Assignor or after a Default has occurred and is continuing, no partial assignment of a Commitment may be made if the portion thereof
intended to be assigned is less than $5,000,000.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(c) | Concurrently with any assignment in favour of an Assignee who is not, at the time of the assignment, party to this Agreement, each Credit Party must confirm that the Assignee is
entitled to the benefit of the Guarantee Agreements.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(d) | Each assignment by a Lender is subject to the prior consent of the Agent and, if made at a time when no Default is continuing, to the prior consent of the Borrower (which consents
will not be unreasonably withheld). However, no such consent will be required if the Assignee is a Lender or an Affiliate of a Lender.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 33 -



---

|(e) | Sections (a) to (d) do not apply to a participation that a Lender may grant to another financial institution provided that no such participation will release any Lender of
its obligations under the Credit Documents.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

17.5 Notes

At the request of a Lender, the Borrower will execute in favour of such Lender a note evidencing its indebtedness to such Lender under this Agreement.

17.6 No Waiver

The omission by
the Agent or any Lender to exercise any of its rights will not be deemed to be a waiver of the exercise of any such right subsequently. The omission by the Agent or any Lender to notify the Borrower of the occurrence of a Default will not be deemed
to be a waiver of the right of the Agent or of such Lender to avail itself of such Default.

17.7 Set-off

The Agent and each Lender are authorized, if an Event of Default has occurred and is continuing, to set off and to apply any and all deposits held for the
Credit Parties against any amount due and payable by the Borrower under the Credit Documents. The Agent or the Lender concerned will promptly notify the Borrower of any such application of payment.

17.8 Indemnification



|(a) | The Borrower must pay on demand the amount of all reasonable costs and expenses (including legal and other professional fees) incurred by the Agent in connection with the Loan and
the preparation, negotiation, execution and administration of the Credit Documents, as well as the reasonable costs and expenses incurred by the Agent or the Lenders in connection with the enforcement of, or the preservation of any rights under, any
Credit Document.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(b) | If any law, regulation, administrative decision or guideline or decision of a Court (i) increases the cost of the Loan for any Lender or (ii) reduces the income receivable
by any Lender from the Loan (including, without limitation, by reason of the imposition of reserves, taxes or requirements as to the capital adequacy of such Lender but in no event by reason of taxes on the overall net income of a Lender), such
Lender may send to the Borrower a statement indicating the amount of such additional cost or reduction of income; in the absence of manifest error, this statement will be conclusive evidence of the amount of such additional cost or reduction of
income and the Borrower must pay forthwith said amount to such Lender.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(c) | In addition to Redeployment Costs, the Borrower must pay on demand the amount of any other cost or loss, if any, suffered by a Lender as a result of the repayment
of the Loan
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 34 -



---

| | before maturity, irrespective of the cause of such repayment (including a repayment resulting from a demand for payment after the occurrence of an Event of
Default). In the absence of manifest error, a statement prepared by the affected Lender indicating the amount of such cost or other loss and the method by which same was calculated will be binding and conclusive.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(d) | The Borrower must indemnify the Agent, the Lenders, their Affiliates and their respective officers, directors, employees and agents and hold them harmless from and against all
losses, liabilities, claims, damages or expenses (including the costs to defend any claim) suffered or incurred by or made against any of them in any manner whatsoever arising from or related to the Credit Documents or the transactions contemplated
thereby (including as a result of any Default or any claim under Environmental Laws in connection with the operations of, or any property owned or operated by, any Credit Party).
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

17.9 Mitigation of costs

Each Lender will use
its best efforts to avoid any additional cost or reduction of income for which the Borrower is required to indemnify such Lender pursuant to Section 17.8(b). However, nothing herein will require any Lender to take any action which would cause
such Lender to incur any expense which would not materially reduce any amount to be received pursuant to Section 17.8(b) or which the Lender determines in its sole judgment to be inadvisable for regulatory, competitive or internal management
reasons. The Borrower will reimburse any Lender for any such expense incurred by such Lender in taking any action pursuant to this Section 17.9.

17.10 Inconsistency

In the event of inconsistency between this Agreement and any other Credit Document, the
provisions of this Agreement must be accorded precedence.

17.11 No Liability of Limited Partners

The obligations of the Borrower under any Credit Documents will not be personally binding upon, nor will resort be had to, the property of any of the
limited partners of the Borrower, their heirs, successors and assigns.

17.12 Corrections of Errors

The Agent is authorized to correct any typographical error or other error of an editorial nature in this Agreement and to substitute such corrected text
in the counterparts of this Agreement, provided that such corrections do not modify the meaning or the interpretation of this Agreement and provided that copies of the corrected texts are remitted to each party.



- 35 -



---

make the applicable transaction.

Dear Sirs/Mesdames:

Re: ACH Limited Partnership / Debt Service Account and Maintenance Account

ACH Limited Partnership (the Customer) has
entered into or will enter into a $250,000,000 term loan with Caisse de depôt et placement du Québec, as agent (the Agent) pursuant to which the Customer has agreed to establish a Debt Service Account and a Maintenance
Account, the whole pursuant to a credit agreement dated as of March 31, 2007 (as amended, restated or otherwise modified from time to time (the Credit Agreement)).

The Customer maintains an account no.  (Maintenance Account) and account no.  (Debt Service Account) (collectively, the Accounts)
with Canadian Imperial Bank of Commerce (CIBC) at its  branch (the Branch of Account) into which the Customer will make deposits from time to time.

In order for the Customer to comply with the requirements of the Credit Agreement, the Customer requests that CIBC acknowledge and agree with the Customer and the Agent
for their benefit, as follows:



|1. | Establishment of the Accounts
|-- | -----------------------------

CIBC has established
and will maintain the Accounts in the name of the Customer, subject to the rights of the Agent as provided for in this Agreement.



|2. | Withdrawals
|-- | -----------

Except as otherwise provided for in
this Agreement, CIBC will be entitled to operate the Accounts in the normal course of its business with the Customer and CIBC will be permitted to honour all withdrawals, debit memos, cheques, payment orders, wire transfers, items and other forms of
payment in accordance with the applicable banking resolutions, authorizations and agreements governing the operation of the Accounts.



|3. | Authorizations and Directions to CIBC
|-- | -------------------------------------

CIBC is
authorized and directed that upon receipt of a notice from the Agent instructing CIBC to block the Accounts (a Stop Notice), CIBC will block the Accounts and (except as otherwise provided for in section 5 of this Agreement) CIBC will
accept only the instructions of the Agent with respect to permitting withdrawals from or the debiting of fees, charges and other amounts to the Accounts. The authorization contained in this section 3 is irrevocable unless the Agent will deliver to
CIBC a written notice (with a copy to the Customer) withdrawing the Stop Notice, whereupon the Customer will again have control over the Accounts.



---

|4. | Fees
|-- | ----

The Customer agrees that it is responsible to
pay CIBC for all fees, charges and expenses relating to the establishment and operation of the Accounts (including CIBCs reasonable legal fees) and all other normal and customary fees, charges and expenses for services that may be provided to
the Customer by CIBC, including but not limited to, debit fees and other normal and customary charges, fees and expenses in connection with wire transfers, business banking services and the operation of the Accounts (all such amounts referred to as
Fees).



|5. | Operation of Accounts After Receipt of Stop Notice
|-- | --------------------------------------------------



| | (a) | From and after receipt by CIBC of a Stop Notice and until this Agreement is terminated or until CIBC receives a written notice withdrawing the Stop Notice, whichever occurs first,
CIBC will not make any charge, debit or offset against any cheques, drafts or other items received for deposit in the Accounts or against any amounts in an Account, provided that CIBC retains the right, at all times, to debit an Account for the
amount of any Fees, any cheques or other forms of payment deposited in such Account and subsequently returned to CIBC unpaid for any reason (whether in accordance with the rules of the Canadian Payment Association or otherwise), any required
adjustment due to clerical error or calculation error and any other debit that CIBC would process against the Accounts in the ordinary course of operating the Accounts (all such amounts referred to as Chargeback Amounts).
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | If debiting an Account for any Fees or Chargeback Amounts creates a debit balance in an Account, CIBC will be entitled to offset any cheques, drafts or any other forms of payment
(including cash deposits received) for deposit in such Account against that debit balance.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Despite any other term of this Agreement, CIBC will have the right to act in accordance with its standard procedures, policies and practices and to debit each Account upon receipt
of and in accordance with any third party demand, including, but not limited to, any court order, notice of garnishment, execution, seizure or governmental direction to pay which is received by CIBC. CIBC agrees to provide the Customer and the Agent
with notice and the details of any such third party deemed forthwith upon receipt thereof.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|6. | Statements/Advices
|-- | ------------------

CIBC will provide the Customer
and, at the request of the Agent, the Agent with monthly statements of account, debit and credit advices and copies of all relevant communications issued or received by CIBC in the normal course of operating the Accounts.



|7. | Liability
|-- | ---------

CIBC undertakes to perform only those
duties that are expressly set forth in this Agreement. The Customer and the Agent agree that CIBC will not be liable for any act or omission taken or made by CIBC or its directors, officers, employees or agents in connection with this Agreement
other than for acts or omissions constituting gross negligence or willful malfeasance of CIBC. In the case of gross negligence or willful malfesance with any act or omission taken or made by CIBC under this Agreement, CIBC will be liable for no more
than the actual damages directly caused by such gross negligence or willful malfesance. In no event will CIBC be liable for any indirect, special or consequential damages even if informed of the possibility of such damages or for any losses or
delays resulting from acts of god, computer malfunctions, interruption of communication facilities, labour difficulties, legal impediments beyond CIBCs control that expressly limit CIBCs power under this Agreement or other causes beyond
CIBCs control.



---

|8. | Indemnity
|-- | ---------

The Customer agrees to indemnify and
save CIBC harmless from and against any and all liabilities, obligations, losses, damages, claims (including, without limitation, any third party claims), penalties, actions, judgments, suits, costs, reasonable expenses or disbursements of any kind
or nature whatsoever (including, without limitation, reasonable legal fees) sustained or incurred by CIBC as a result of entering into this Agreement or the performance by CIBC of any of its obligations hereunder, including, without limitation,
complying with any Stop Notice, except for any liability, loss, damage or expense resulting from CIBCs gross negligence or willful malfesance.



|9. | No Duty to Inquire
|-- | ------------------

Any notice or instruction
purporting to be given by the Agent under this Agreement will be conclusive authority for CIBC to act in accordance with that notice or instruction. CIBC is not obliged or required to monitor any requirements or obligations of the Customer pursuant
to this Agreement and has no duty to question any notice or instruction provided by the Agent to CIBC. The Customer authorizes CIBC to act on any such notice or instruction and waives any claim or action against CIBC in connection therewith.



|10. | Termination/Closing of the Accounts
|--- | -----------------------------------

CIBC may
terminate this Agreement for any reason by providing thirty (30) days prior written notice to the Customer and the Agent. CIBC may also terminate this Agreement effective immediately if any proceeding in bankruptcy, receivership,
liquidation or insolvency is commenced against the Customer or its property or if the Customer becomes insolvent, commits any act of bankruptcy, ceases to do business as a going concern, or seeks any arrangement or compromise with its creditors
under any statute or otherwise upon written notice to the Agent and the Customer. CIBC may close an Account in accordance with its usual banking practice and upon written notice to the Customer and the Agent provided that, upon the Agents
instructions, CIBC will transfer all funds in the applicable Account to the Agent.

The Agent may terminate this Agreement by providing ten
(10) days prior written notice to the Customer and CIBC.



|11. | Assignment
|--- | ----------

The Customer will not have the right to
assign this Agreement. The Agent may assign this Agreement to a successor agent in accordance with the provisions of the Credit Agreement provided that the prior consent of CIBC is obtained, which consent will not be unreasonably withheld or
delayed. CIBC may assign its rights and obligations under this Agreement, without the approval of the Agent or the Customer, to an affiliate of CIBC or any entity which acquires all or substantially all of assets of CIBC or to any subsidiary or
affiliate or successor in a merger, amalgamation or acquisition of CIBC.



|12. | CIBC is not a Fiduciary or Trustee
|--- | ----------------------------------

Nothing in this
Agreement constitutes CIBC as a trustee or a fiduciary in respect of either the Customer or the Agent. The Customer and the Agent agree that CIBC will have no other obligations in respect of the Accounts or the funds held in the Accounts except for
those obligations set out in this Agreement.



|13. | Notices
|--- | -------

All notices, including, without
limitation, Stop Notice, statements of account, debit and credit advices, returned items, general correspondence and termination notices, may be sent by the parties to this Agreement to the following addresses, or to such other address as any party
receiving notices will designate to the other parties, in writing from time to time:
