     (2) If, in respect of any Currency Excess, the repayments made by the Borrower have not
completely removed such Currency Excess (the remainder thereof being herein called the “Currency
Excess Deficiency”), the Borrower shall within the aforementioned 5 or 20 Banking Days, as the case
may be, after receipt of the aforementioned request of the Agent, place an amount equal to the
Currency Excess Deficiency on deposit with the Agent in an interest-bearing account with interest
at rates prevailing at the time of deposit for the account of the Borrower, to be assigned to the
Agent on behalf of the Lenders by instrument satisfactory to the Agent and to be applied to
maturing Bankers’ Acceptances or Libor Loans (converted if necessary at the exchange rate for
determining the Equivalent Amount on the date of such application). The Agent is hereby
irrevocably directed by the Borrower to apply any such sums on deposit to maturing Loans as
provided in the preceding sentence. In lieu

 

-26-

of providing funds for the Currency Excess Deficiency, as provided in the preceding provisions
of this Section, the Borrower may within the said period of 5 or 20 Banking Days, as the case may
be, provide to the Agent an irrevocable standby letter of credit in an amount equal to the Currency
Excess Deficiency and for a term which expires not sooner than 10 Banking Days after the date of
maturity of the relevant Bankers’ Acceptances or Libor Loans, as the case may be; such letter of
credit shall be issued by a financial institution, and shall be on terms and conditions, acceptable
to the Agent in its sole discretion. The Agent is hereby authorized and directed to draw upon such
letter of credit and apply the proceeds of the same to Bankers’ Acceptances or Libor Loans as they
mature. Upon the Currency Excess being eliminated as aforesaid or by virtue of subsequent changes
in the exchange rate for determining the Equivalent Amount, then, provided no Default or Event of
Default is then continuing, such funds on deposit, together with interest thereon, or such letters
of credit shall be returned to the Borrower, in the case of funds on deposit, or shall be cancelled
or reduced in amount, in the case of letters of credit.

2.18 Permitted Increase in Credit Facility

          The Borrower may, at any time and from time to time, increase the maximum principal amount of
the Credit Facility by adding additional financial institutions as Lenders hereunder or by
increasing the Commitments of existing Lenders with (in the latter case) the consent of such
increasing Lenders, or any combination thereof. The right to increase the maximum principal amount
of the Credit Facility as aforesaid shall be subject to the following (for each such increase):

	 	(a)	 	no Default or Event of Default shall have occurred and be continuing and the
Borrower shall have delivered to the Agent a certificate of an officer of the Borrower
confirming the same and confirming (i) its corporate authorization to make such
increase, (ii) the truth and accuracy in all material respects of its representations
and warranties contained in Section 8.1 hereof as of such date, other than any such
representations and warranties which expressly speak as of an earlier date and (iii)
that no consents, approvals or authorizations are required for such increase (except as
have been unconditionally obtained and are in full force and effect, unamended), each
as at the effective date of such increase;
	 
	 	(b)	 	the Borrower shall have delivered to the Agent an opinion of its legal counsel
in form and substance as may be required by the Agent, acting reasonably (and such
opinion shall, inter alia, opine as to the corporate authorization of the Borrower to
effect such increase);
	 
	 	(c)	 	after giving effect to any such increase, the maximum principal amount of the
Credit Facility shall not exceed U.S. $2,000,000,000;
	 
	 	(d)	 	the Agent shall have consented to any additional financial institution becoming
a Lender, such consent not to be unreasonably withheld, conditioned or delayed; and
	 
	 	(e)	 	the Borrower and the increasing existing Lender or the financial institution being added, as
the case may be, shall execute and deliver such documentation as is required by the Agent, acting
reasonably, to effect the increase in question (including the partial assignment of Loans or
purchase of participations from Lenders to the extent necessary to ensure that, after giving effect
to such increase, each Lender holds its Rateable Portion of each outstanding Loan under the Credit
Facility) and, if applicable, to add any such new financial institution as a Lender under the
Documents.

2.19 Hostile Acquisitions

     (1) In the event the Borrower wishes to utilize the proceeds of one or more Loans under the
Credit Facility to, or to provide funds to any Subsidiary to, finance a Hostile Acquisition, then
the following steps shall be followed:

	 	(a)	 	at least five (5) Banking Days prior to the delivery to the Agent of any
Drawdown Notice pursuant to Section 2.7 requesting one or more Loans under the Credit
Facility intended to be used to finance such Hostile Acquisition, the Borrower shall
notify the Agent and shall provide the Agent with particulars of such Hostile
Acquisition, including particulars in sufficient detail to enable each Lender to
determine whether it has a conflict of interest if the proceeds of Loans from such
Lender are used by the Borrower to finance such Hostile Acquisition;
	 
	 	(b)	 	promptly after receipt of such notice and particulars from the Borrower, the
Agent shall (i) notify an appropriate officer of each Lender and provide such
particulars to such officer and (ii) confirm receipt (other than by way of an automated
response) of such notice and particulars by each such officer;
	 
	 	(c)	 	within three (3) Banking Days of such confirmation by the Agent of each such
appropriate officer being so advised, each Lender shall notify the Agent of such
Lender’s determination as to whether (i) such a conflict of interest exists or (ii) the
funding of such Hostile Acquisition would contravene an internal policy of general
application of such Lender (each such determination to be made by each such Lender in
the exercise of its sole discretion, having regard to such considerations as it deems
appropriate); provided that in the event such Lender does not so notify the Agent
within such three (3) Banking Day period, such Lender shall be deemed to have notified
the Agent that it has no such conflict of interest or contravention; and
	 
	 	(d)	 	the Agent shall promptly notify the Borrower of each such Lender’s
determination,

and, in the event that any Lender has such a conflict of interest or the funding would contravene
such a policy (each, a “Conflicted Lender”), then upon such Conflicted Lender so notifying the
Agent, the Conflicted Lender shall have no obligation to provide Loans to finance such Hostile
Acquisition, notwithstanding any other provision of this Agreement to the contrary; provided,
however, that each other Lender (each, a “Non-Conflicted Lender”) which has, or is deemed to have,
no such conflict of interest or contravention shall have an obligation, up to the amount of its
Commitment, to provide Loans to finance such Hostile Acquisition, and the Loans to finance such
Hostile Acquisition shall be provided by each Non-Conflicted Lender in accordance with the ratio,
determined prior to the provision of any Loans to finance such Hostile Acquisition, that the
Commitment of such Non-Conflicted Lender under the Credit Facility bears to the aggregate
Commitments of all Non-Conflicted Lenders under the Credit Facility.

     (2) If Loans are used to finance a Hostile Acquisition and there are Conflicted Lenders,
subsequent Loans under the Credit Facility shall be funded firstly by Conflicted Lenders, up to the
amount of their Commitments, and subsequent repayments under the Credit Facility shall be applied
firstly to Non-Conflicted Lenders, in each case, until such time as the proportion that the amount
of each Lender’s Outstanding Principal under the Credit Facility bears to the amount of the total
Outstanding Principal of all Lenders is equal to such proportion which would have been in effect
but for the application of this Section 2.19.

owing by the Borrower to the Lenders hereunder. The Agent shall enter in the foregoing accounts
details of all amounts from time to time owing, paid or repaid by the Borrower hereunder. The

ARTICLE 5

PAYMENTS OF INTEREST AND FEES

5.1 Interest on Canadian Prime Rate Loans

          The Borrower shall pay interest on each Canadian Prime Rate Loan owing by it during each
Interest Period applicable thereto in Canadian Dollars at a rate per annum equal to the Canadian
Prime Rate in effect from time to time during such Interest Period plus the Applicable Pricing
Rate. Each determination by the Agent of the Canadian Prime Rate applicable from time to time
during an Interest Period shall be prima facie evidence thereof. Such interest shall accrue daily
and shall be payable in arrears on each Interest Payment Date for such Loan for the period from and
including the Drawdown Date or the preceding Conversion Date or Interest Payment Date, as the case
may be, for such Loan to and including the day preceding such Interest Payment Date and shall be
calculated on the principal amount of the Canadian Prime Rate Loan outstanding during such period
and on the basis of the actual number of days elapsed in a year of 365 days. Changes in the
Canadian Prime Rate shall cause an immediate adjustment of the interest rate applicable to such
Loans without the necessity of any notice to the Borrower.

5.2 Interest on U.S. Base Rate Loans

          The Borrower shall pay interest on each U.S. Base Rate Loan owing by it during each Interest
Period applicable thereto in United States Dollars at a rate per annum equal to the U.S. Base Rate
in effect from time to time during such Interest Period plus the Applicable Pricing Rate. Each
determination by the Agent of the U.S. Base Rate applicable from time to time during an Interest
Period shall be prima facie evidence thereof. Such interest, shall accrue daily and be payable in
arrears on each Interest Payment Date for such Loan for the period from and including the Drawdown
Date or the preceding Conversion Date or Interest Payment Date, as the case may be, for such Loan
to and including the day preceding such Interest Payment Date and shall be calculated on the
principal amount of the U.S. Base Rate Loan outstanding during such period and on the basis of the
actual number of days elapsed in a year of 365 days. Changes in the U.S. Base Rate shall cause an
immediate adjustment of the interest rate applicable to such Loans without the necessity of any
notice to the Borrower.

5.3 Interest on Libor Loans

          The Borrower shall pay interest on each Libor Loan owing by it during each Interest Period
applicable thereto in United States Dollars at a rate per annum, calculated on the basis of a 360
day year, equal to the Libor Rate with respect to such Interest Period plus the Applicable Pricing
Rate. Each determination by the Agent of the Libor Rate applicable to an Interest Period shall be
prima facie evidence thereof. Such interest shall accrue daily and shall be payable in arrears on each
Interest Payment Date for such Loan for the period from and including the Drawdown Date or the
preceding Rollover Date, Conversion Date or Interest Payment Date, as the

 

-30-

case may be, for such Loan to and including the day preceding such Interest Payment Date and shall be calculated on the
principal amount of the Libor Loan outstanding during such period and on the basis of the actual
number of days elapsed divided by 360.

5.4 Interest Act (Canada)

     (1) Whenever a rate of interest hereunder is calculated on the basis of a year (the “deemed
year”) which contains fewer days than the actual number of days in the calendar year of
calculation, such rate of interest shall be expressed as a yearly rate for purposes of the Interest
Act (Canada) by multiplying such rate of interest by the actual number of days in the calendar year
of calculation and dividing it by the number of days in the deemed year.

     (2) Whenever a rate of interest or other rate per annum hereunder is expressed or calculated
on the basis of a year of 360 days, such rate of interest or other rate shall be expressed as a
rate per annum, calculated on the basis of a 365-day year, by multiplying such rate of interest or
other rate by 365 and dividing it by 360.

5.5 Nominal Rates; No Deemed Reinvestment

          The principle of deemed reinvestment of interest shall not apply to any interest calculation
under this Agreement; all interest payments to be made hereunder shall be paid without allowance or
deduction for deemed reinvestment or otherwise, before and after maturity, default and judgment.
The rates of interest specified in this Agreement are intended to be nominal rates and not
effective rates. Interest calculated hereunder shall be calculated using the nominal rate method
and not the effective rate method of calculation.

5.6 Standby Fees

     (1) The Borrower shall pay to the Agent for the account of the Lenders a standby fee in United
States Dollars in respect of the Credit Facility calculated at a rate per annum equal to the
Applicable Pricing Rate on the amount, if any, by which the amount of the Outstanding Principal
under the Credit Facility for each day in the period of determination is less than the maximum
principal amount of the Credit Facility on such day. Fees determined in accordance with this
Section shall accrue daily from and after the date hereof and be payable by the Borrower (a)
quarterly in arrears, (b) on cancellation in full of the Credit Facility, and (c) on the Maturity
Date.

     (2) As of: (a) January 1, April 1, July 1 and October 1 in each year, (b) the date of any
cancellation in full of the Credit Facility, and (c) the Maturity Date, the Agent shall determine
the standby fees under this Section in respect of the Credit Facility for the period from and
including the date hereof or the date of the immediately preceding determination, as the case may
be, to but excluding that date of determination and shall deliver to the Borrower a written request
for payment of the standby fees so determined, as detailed therein. The Borrower shall pay to the
Agent for the account of the Lenders the standby fees referred to above within 5 Banking Days after
receipt of each such written request.

5.7 Agent’s Fees

          The Borrower shall (from time to time) pay to the Agent, for its own account, the annual
agency fee and other amounts set forth in the Agency Fee Agreement by the payment dates set forth
therein.

5.8 Interest on Overdue Amounts

          Notwithstanding any other provision hereof, in the event that any amount due hereunder
(including, without limitation, any interest payment) is not paid when due (whether by acceleration
or otherwise), the Borrower shall pay interest on such unpaid amount (including, without
limitation, interest on interest), if and to the fullest extent permitted by applicable law, from
the date that such amount is due until the date that such amount is paid in

 

-31-

full (but excluding the date of such payment if the payment is received for value at the required place of payment on the
date of such payment), and such interest shall accrue daily, be calculated and compounded monthly
and be payable on demand, after as well as before maturity, default and judgment, at a rate per
annum that is equal to (a) in respect of amounts due in Canadian Dollars, the rate of interest then
payable on Canadian Prime Rate Loans plus 2.0% per annum or (b) in respect of amounts due in United
States Dollars, the rate of interest then payable on U.S. Base Rate Loans plus 2.0% per annum.

5.9 Waiver

          To the extent permitted by applicable law, the covenant of the Borrower to pay interest at the
rates provided herein shall not merge in any judgment relating to any obligation of the Borrower to
the Lenders or the Agent and any provision of the Interest Act (Canada) or Judgment Interest Act
(Alberta) which restricts any rate of interest set forth herein shall be inapplicable to this
Agreement and is hereby waived by the Borrower.

5.10 Maximum Rate Permitted by Law

          No interest or fee to be paid hereunder shall be paid at a rate exceeding the maximum rate
permitted by applicable law. In the event that such interest or fee exceeds such maximum rate,
such interest or fees shall be reduced or refunded, as the case may be, so as to be payable at the
highest rate recoverable under applicable law.

ARTICLE 6

BANKERS’ ACCEPTANCES

6.1 Bankers’ Acceptances

          The Borrower may give the Agent notice that Bankers’ Acceptances will be required under the
Credit Facility pursuant to a Drawdown, Rollover or Conversion.

6.2 Acceptance Fees

          Upon the acceptance by a Lender of a Bankers’ Acceptance, the Borrower shall pay to the Agent
for the account of such Lender an acceptance fee in Canadian Dollars equal to the Applicable
Pricing Rate calculated on the principal amount at maturity of such Bankers’ Acceptance and for the
period of time from and including the date of acceptance to but excluding the maturity date of such
Bankers’ Acceptance and calculated on the basis of the number of days elapsed in a year of 365
days.

6.3 Form and Execution of Bankers’ Acceptances

          The following provisions shall apply to each Bankers’ Acceptance hereunder:

	 	(a)	 	the face amount at maturity of each draft drawn by the Borrower to be accepted
as a Bankers’ Acceptance shall be Cdn. $100,000 and integral multiples thereof;
	 
	 	(b)	 	the term to maturity of each draft drawn by the Borrower to be accepted as a
Bankers’ Acceptance shall, subject to market availability as determined by all of the
Lenders, be 1, 2, 3 or 6 months (or such other longer or shorter term as agreed by the
Lenders), as selected by the Borrower in the relevant Drawdown Notice, Rollover Notice
or Conversion Notice, and each Bankers’ Acceptance shall be payable and mature on the
last day of the Interest Period selected by the Borrower for such Bankers’ Acceptance
(which, for certainty, pursuant to the definition of “Interest Period” shall be on or
prior to the Maturity Date);

 

-32-

	 	(c)	 	each draft drawn by the Borrower and presented for acceptance by a Lender shall
be drawn on the standard form of such Lender in effect at the time; provided, however,
that the Agent may require the Lenders to use a generic form of Bankers’ Acceptance, in
a form satisfactory to each Lender, acting reasonably, provided by the Agent for such
purpose in place of the Lenders’ own forms;
	 
	 	(d)	 	subject to Section 6.3(e) below, Bankers’ Acceptances shall be signed by duly
authorized officers of the Borrower or, in the alternative, the signatures of such
officers may be mechanically reproduced in facsimile thereon and Bankers’ Acceptances
bearing such facsimile signatures shall be binding on the Borrower as if they had been
manually executed and delivered by such officers on behalf of the Borrower;
notwithstanding that any person whose manual or facsimile signature appears on any
Bankers’ Acceptance may no longer be an authorized signatory for the Borrower on the
date of issuance of a Bankers’ Acceptance, such signature shall nevertheless be valid
and sufficient for all purposes as if such authority had remained in force at the time
of such issuance and any such Bankers’ Acceptance shall be binding on the Borrower; and
	 
	 	(e)	 	in lieu of signing Bankers’ Acceptances in accordance with Section 6.3(d)
above, the Borrower may provide a Power of Attorney to a Lender; for so long as a Power
of Attorney is in force with respect to a given Lender, such Lender shall execute and
deliver Bankers’ Acceptances on behalf of the Borrower in accordance with the
provisions thereof and, for certainty, all references herein to drafts drawn by the
Borrower, Bankers’ Acceptances executed by the Borrower or similar expressions shall be
deemed to include Bankers’ Acceptances executed in accordance with a Power of Attorney,
unless the context otherwise requires.

6.4 Power of Attorney; Provision of Bankers’ Acceptances to Lenders

     (1) Unless revoked with respect to a given Lender in accordance herewith, the Borrower hereby
appoints each Lender, acting by any authorized signatory of the Lender in question, the attorney of
the Borrower:

	 	(a)	 	to sign for and on behalf and in the name of the Borrower as drawer, drafts in
such Lender’s standard form which are depository bills as defined in the Depository
Bills and Notes Act (Canada) (the “DBNA”), payable to a “clearing house” (as defined in
the DBNA) including CDS Clearing and Depository Services Inc., or its nominee, CDS &
Co. (the “clearing house”);
	 
	 	(b)	 	for drafts which are not depository bills, to sign for and on behalf and in the
name of the Borrower as drawer and to endorse on its behalf, Bankers’ Acceptances drawn
on the Lender payable to the order of the undersigned or payable to the order of such
Lender;
	 
	 	(c)	 	to fill in the amount, date and maturity date of such Bankers’ Acceptances; and
	 
	 	(d)	 	to deposit and/or deliver such Bankers’ Acceptances which have been accepted by
such Lender,

provided that such acts in each case are to be undertaken by the Lender in question strictly in
accordance with instructions given to such Lender by the Borrower as provided in this Section 6.4.
For certainty, signatures of any authorized signatory of a Lender may be mechanically reproduced in
facsimile on Bankers’ Acceptances in accordance herewith and such facsimile signatures shall be
binding and effective as if they had been manually executed by such authorized signatory of such
Lender.

          Instructions from the Borrower to a Lender relating to the execution, completion, endorsement,
deposit and/or delivery by that Lender on behalf of the Borrower of Bankers’ Acceptances which the
Borrower wishes to submit to the Lender for acceptance by the Lender shall be communicated by the
Borrower in writing to the Agent by delivery to the Agent of Drawdown Notices, Conversion Notices
and Rollover Notices, as the case

 

-33-

may be, in accordance with this Agreement which, in turn, shall be communicated by the Agent, on behalf of the Borrower, to the Lender.

          The communication in writing by the Borrower, or on behalf of the Borrower by the Agent, to
the Lender of the instructions set out in the Drawdown Notices, Conversion Notices and Rollover
Notices referred to above shall constitute (a) the authorization and instruction of the Borrower to
the Lender to sign for and on behalf and in the name of the Borrower as drawer the requested
Bankers’ Acceptances and to complete and/or endorse Bankers’ Acceptances in accordance with such
information as set out above and (b) the request of the Borrower to the Lender to accept such
Bankers’ Acceptances and deposit the same with the clearing house or deliver the same, as the case
may be, in each case in accordance with this Agreement and such instructions. The Borrower
acknowledges that a Lender shall not be obligated to accept any such Bankers’ Acceptances except in
accordance with the provisions of this Agreement.

          A Lender shall be and it is hereby authorized to act on behalf of the Borrower upon and in
compliance with instructions communicated to that Lender as provided herein if the Lender
reasonably believes such instructions to be genuine. If a Lender accepts Bankers’ Acceptances
pursuant to any such instructions, that Lender shall confirm particulars of such instructions and
advise the Agent that it has complied therewith by notice in writing addressed to the Agent and
served personally or sent by facsimile transmission or other electronic transmission in accordance
with the provisions hereof. A Lender’s actions in compliance with such instructions, confirmed and
advised to the Agent by such notice, shall be conclusively deemed to have been in accordance with
the instructions of the Borrower.

          This Power of Attorney may be revoked by the Borrower with respect to any particular Lender at
any time upon not less than 5 Banking Days’ prior written notice served upon the Lender in question
and the Agent, provided that no such revocation shall reduce, limit or otherwise affect the
obligations of the Borrower in respect of any Bankers’ Acceptance executed, completed, endorsed,
deposited and/or delivered in accordance herewith prior to the time at which such revocation
becomes effective.

     (2) Unless the Borrower has provided Powers of Attorney to the Lenders, to facilitate
Drawdowns, Rollovers or Conversions of Bankers’ Acceptances, the Borrower shall, upon execution of
this Agreement and thereafter from time to time as required by all Lenders, provide to the Agent
for delivery to each Lender drafts drawn in blank by the Borrower (pre-endorsed and otherwise in
fully negotiable form, if applicable) in quantities sufficient for each Lender to fulfil its
obligations hereunder. Any such pre-signed drafts which are delivered by the Borrower to the Agent
or a Lender shall be held in safekeeping by the Agent or such Lender, as the case may be, with the same degree of care as
if they were the Agent’s or such Lender’s property, and shall only be dealt with by the Lenders and
the Agent in accordance herewith. No Lender shall be responsible or liable for its failure to make
its share of any Drawdown, Rollover or Conversion of Bankers’ Acceptances required hereunder if the
cause of such failure is, in whole or in part, due to the failure of the Borrower to provide such
pre-signed drafts to the Agent (for delivery to such Lender) on a timely basis.

     (3) By 12:00 noon (Toronto time) on the applicable Drawdown Date, Conversion Date or Rollover
Date, the Borrower shall (a) either deliver to each Lender in Toronto, or, if previously delivered,
be deemed to have authorized each Lender to complete and accept, or (b) where the Borrower has
previously executed and delivered a Power of Attorney to the Lender, be deemed to have authorized
each such Lender to sign on behalf of the Borrower, complete and accept, drafts drawn by the
Borrower on such Lender in a principal amount at maturity equal to such Lender’s share of the
Bankers’ Acceptances specified by the Borrower in the relevant Drawdown Notice, Conversion Notice
or Rollover Notice, as the case may be, as notified to the Lenders by the Agent.

 

-34-

6.5 Mechanics of Issuance

     (1) Upon receipt by the Agent of a Drawdown Notice, Conversion Notice or Rollover Notice from
the Borrower requesting the issuance of Bankers’ Acceptances, the Agent shall promptly notify the
Lenders thereof and advise each Lender of the aggregate face amount of Bankers’ Acceptances to be
accepted by such Lenders, the date of issue and the Interest Period for such Loan; the
apportionment among the Lenders of the face amounts of Bankers’ Acceptances to be accepted by each
Lender shall be determined by the Agent by reference and in proportion to the respective Commitment
of each Lender, provided that, when such apportionment cannot be evenly made, the Agent shall round
allocations amongst such Lenders consistent with the Agent’s normal money market practices.

     (2) On each Drawdown Date, Rollover Date or Conversion Date involving the issuance of Bankers’
Acceptances:

	 	(a)	 	before 11:00 a.m. (Toronto time) on such date, the Agent shall determine the
CDOR Rate in respect of an issue of bankers’ acceptances in a comparable amount and
with comparable maturity to the Bankers’ Acceptances proposed to be issued on such
date;
	 
	 	(b)	 	on or about 11:00 a.m. (Toronto time) on such date, the Agent shall advise each
Lender of the applicable BA Discount Rate;
	 
	 	(c)	 	each Lender shall complete and accept, in accordance with the Drawdown Notice,
Conversion Notice or Rollover Notice delivered by the Borrower and advised by the Agent
in connection with such issue, its share of the Bankers’ Acceptances to be issued on
such date and shall purchase such Bankers’ Acceptances for its own account at a
purchase price which reflects the BA Discount Rate applicable to such issue; and
	 
	 	(d)	 	in the case of a Drawdown, each Lender shall, for same day value on the
Drawdown Date, remit the Discount Proceeds or advance the BA Equivalent Advance, as the
case may be, payable by such Lender (net of the acceptance fee payable to such Lender
pursuant to Section 6.2) to the Agent for the account of the Borrower; the Agent shall
make such funds available to the Borrower for same day value on such date.

     (3) Each Lender may at any time and from time to time hold, sell, rediscount or otherwise
dispose of any or all Bankers’ Acceptances accepted and purchased by it for its own account.

6.6 Rollover, Conversion or Payment on Maturity

          In anticipation of the maturity of Bankers’ Acceptances, the Borrower shall, subject to and in
accordance with the requirements hereof, do one or a combination of the following with respect to
the aggregate face amount at maturity of all such maturing Bankers’ Acceptances:

	 	(a)	 	(i) deliver to the Agent a Rollover Notice that the Borrower intends to draw
and present for acceptance on the maturity date new Bankers’ Acceptances in an
aggregate face amount up to the aggregate amount of the maturing Bankers’ Acceptances
and (ii) on the maturity date pay to the Agent for the account of the Lenders an
additional amount equal to the difference between the aggregate face amount of the
maturing Bankers’ Acceptances and the Discount Proceeds of such new Bankers’
Acceptances;
	 
	 	(b)	 	(i) deliver to the Agent a Conversion Notice requesting a Conversion of the
maturing Bankers’ Acceptances to another type of Loan under the Credit Facility and
(ii) on the maturity date pay to the Agent for the account of the Lenders an amount
equal to the difference, if any, between the 

 

-35-

	 	 	 	aggregate face amount of the maturing Bankers’ Acceptances and the amount of the Loans into which Conversion is requested; or

	 	(c)	 	on the maturity date of the maturing Bankers’ Acceptances, pay to the Agent for
the account of the Lenders an amount equal to the aggregate face amount of such
Bankers’ Acceptances.

If the Borrower fails to so notify the Agent or make such payments on maturity, the Agent shall
effect a Conversion into a Canadian Prime Rate Loan of the entire amount of such maturing Bankers’
Acceptances as if a Conversion Notice had been given by the Borrower to the Agent to that effect.

6.7 Restriction on Rollovers and Conversions

          Subject to the other provisions hereof, Conversions and Rollovers of Bankers’ Acceptances may
only occur on the maturity date thereof.

6.8 Rollovers

          In order to satisfy the continuing liability of the Borrower to a Lender for the face amounts
of maturing Bankers’ Acceptances accepted by such Lender, the Lender shall receive and retain for
its own account the Discount Proceeds of new Bankers’ Acceptances issued on a Rollover, and the
Borrower shall on the maturity date of the Bankers’ Acceptances being rolled over pay to the Agent
for the account of the Lenders an amount equal to the difference between the face amounts of the
maturing Bankers’ Acceptances and the Discount Proceeds from the new Bankers’ Acceptances together
with the acceptance fees to which the Lenders are entitled pursuant to Section 6.2.

6.9 Conversion into Bankers’ Acceptances

          In respect of Conversions into Bankers’ Acceptances, in order to satisfy the continuing
liability of the Borrower to the Lenders for the amount of the converted Loan, each Lender shall
receive and retain for its own account the Discount Proceeds of the Bankers’ Acceptances issued
upon such Conversion, and the Borrower shall on the Conversion Date pay to the Agent for the
account of the Lenders an amount equal to the difference between the principal amount of the
converted Loan and the aggregate Discount Proceeds from the Bankers’ Acceptances issued on such
Conversion, together with the acceptance fees to which the Lenders are entitled pursuant to Section
6.2.

6.10 Conversion from Bankers’ Acceptances

          In order to satisfy the continuing liability of the Borrower to the Lenders for an amount
equal to the aggregate face amount of the maturing Bankers’ Acceptances converted to another type
of Loan, the Agent shall record the obligations of the Borrower to the Lenders in respect of those
maturing Bankers’ Acceptances as Loans of the type into which such continuing liability has been
converted.

6.11 BA Equivalent Advances

          Notwithstanding the foregoing provisions of this Article, a Non-Acceptance Lender shall, in
lieu of accepting Bankers’ Acceptances, make a BA Equivalent Advance. The amount of each BA
Equivalent Advance shall be equal to the Discount Proceeds which would be realized from a
hypothetical sale of those Bankers’ Acceptances which, but for this Section, such Lender would
otherwise be required to accept as part of such a Drawdown of, Conversion into or Rollover of
Bankers’ Acceptances. To determine the amount of such Discount Proceeds, the hypothetical sale
shall be deemed to take place at the applicable BA Discount Rate for such Loan. Any BA Equivalent
Advance shall be made on the relevant Drawdown Date, Rollover Date or Conversion Date as the case
may be and shall remain outstanding for the term of the relevant Bankers’ Acceptances. Concurrent with

 

-36-

the making of a BA Equivalent Advance, a Non-Acceptance Lender shall be entitled to deduct
therefrom an amount equal to the acceptance fee which, but for this Section, such Lender would
otherwise be entitled to receive as part of such Loan. Subject to Section 6.6, upon the maturity
date for such Bankers’ Acceptances, the Borrower shall pay to each Non-Acceptance Lender an amount
equal to the face amount at maturity of the Bankers’ Acceptances which, but for this Section, such
Lender would otherwise be required to accept as part of such a Drawdown of, Conversion into or
Rollover of Bankers’ Acceptances as repayment of the amount of its BA Equivalent Advance plus
payment of the interest accrued and payable thereon to such maturity date.

          All references herein to “Loans” and “Bankers’ Acceptances” shall, unless otherwise expressly
provided herein or unless the context otherwise requires, be deemed to include BA Equivalent
Advances made by a Non-Acceptance Lender as part of a Drawdown of, Conversion into or Rollover of
Bankers’ Acceptances.

6.12 Termination of Bankers’ Acceptances

          If at any time a Lender ceases to accept bankers’ acceptances in the ordinary course of its
business, such Lender shall be deemed to be a Non-Acceptance Lender and shall make BA Equivalent
Advances in lieu of accepting Bankers’ Acceptances under this Agreement.

          All payments of principal, interest, fees or other amounts to be made by the Agent to the
Lenders pursuant to this Agreement shall be made for value on the day required hereunder, provided

free and clear of, and without deduction or withholding for or on account of, any and all present
or future Taxes and all liabilities with respect thereto imposed, levied, collected, withheld or
assessed by any Governmental Authority imposed on the Agent or the Lenders, or by or on behalf of
the foregoing, excluding Taxes imposed with respect to such payments by such Governmental Authority
if such Taxes are imposed on or measured by reference to or in respect of the overall net income or

transfer, registration, excise, issues, documentary or other taxes, charges or similar levies which
arise from any payment made under this
Agreement or the Loans or in respect of the execution, delivery or registration or the
compliance with this Agreement or the other Documents contemplated hereunder. The Borrower shall
indemnify and hold harmless the Agent and the Lenders for the full amount of all of the foregoing
Taxes or other amounts paid or payable by the Agent or the Lenders and any liability (including
penalties, interest, additions to tax and reasonable out-of-pocket expenses) resulting therefrom or
with respect thereto which arise from any payment made under or pursuant to this Agreement or the

or other amount required to be paid to the Agent or the Lenders hereunder, or if any liability
therefor shall be imposed or shall arise from or in respect of any sum payable hereunder, then the
sum payable to the Agent or the Lenders hereunder shall be increased as may be necessary so that
after making all required deductions, withholdings, and additional income tax payments attributable
thereto (including deductions, withholdings or income tax payable for additional sums payable under
this provision) the Agent or the Lenders, as the case may be, receive an amount equal to the amount
they would have received had no such deductions or withholdings been made or if such additional
taxes had not been imposed; in addition, the Borrower shall pay the full amount deducted or
withheld for such liabilities to the relevant taxation authority or other authority in accordance
with applicable law, such payment to be made (if the liability is imposed on the Borrower) for its
own account or (if the liability is imposed on the Agent or the Lenders) on behalf of and in the
name of the Agent or the Lenders, as the case may be. If the liability is imposed on the Agent or
the Lenders, the Borrower shall deliver to the Agent or the Lenders evidence satisfactory to the

7.6 Set Off

     (1) In addition to any rights now or hereafter granted under applicable law and not by way of
limitation of any such rights, upon the occurrence of an Event of Default which remains unremedied
(whether or not the Loans have been accelerated hereunder), the Agent and each Lender shall have
the right (and are hereby authorized by the Borrower) at any time and from time to time to combine
all or any of the Borrower’s accounts with the Agent or the Lender, as the case may be, and to set
off and to appropriate and to apply any and all deposits (general or special, term or demand)
including, but not limited to, indebtedness evidenced by certificates of deposit whether matured or
unmatured, and any other indebtedness at any time held by the Borrower or owing by such Lender or
the Agent, as the case may be, to or for the credit or account of the Borrower against and towards
the satisfaction of any Obligations owing by the Borrower, and may do so notwithstanding that the
balances of such accounts and the liabilities are expressed in different currencies, and the Agent
and each Lender are hereby authorized to effect any necessary currency conversions at the noon spot
rate of exchange announced by the Bank of Canada on the Banking Day before the day of conversion.

     (2) The Agent or the applicable Lender, as the case may be, shall notify the Borrower of any
such set-off from the Borrower’s accounts within a reasonable period of time thereafter, although
the Agent or the Lender, as the case may be, shall not be liable to the Borrower for its failure to
so notify.

7.7 Margin Changes; Adjustments for Margin Changes; Notice of Rating Changes

     (1) Changes in Applicable Pricing Rates shall be effective:

	 	(a)	 	on the Banking Day immediately following any change in the relevant Debt Rating
(or when the Borrower ceases to have a Debt Rating, if applicable) which results in a
change in the Applicable Pricing Rate in accordance with the definition thereof; and
	 
	 	(b)	 	without the necessity of notice to the Borrower.

     (2) For any Loans outstanding as of the effective date of a change in an Applicable Pricing
Rate:

	 	(a)	 	in the case of increases in such rates per annum, the Borrower shall pay to the
Agent for the account of the Lenders such additional interest or fees, as the case may
be, as may be required to give effect to the relevant increases in the interest or fees
payable on or in respect of such Loans from and as of the effective date of the
relevant increase in rates; and
	 
	 	(b)	 	in the case of decreases in such rates per annum, the Borrower shall receive a
credit against subsequent interest payable on Loans or fees payable pursuant to Section
6.2, as the case may be, to the extent necessary to give effect to the relevant
decreases in the interest or fees payable on or in respect of such Loans from and as of
the effective date of the relevant decrease in rates.

     (3) The additional payments required by Section 7.7(2)(a) shall be made on the last Banking
Day of the calendar month immediately following the calendar month in which the changes in
Applicable Pricing Rates are effective. The adjustments required by Section 7.7(2)(b) shall be
accounted for in successive interest and fee payments by the Borrower until the amount of the
credit therein contemplated has been fully applied; provided that, upon satisfaction in full of all
Obligations and cancellation of the Credit Facility in accordance herewith, the Lenders shall pay
to the Borrower an amount equal to any such credit which remains outstanding.

     (4) The Borrower hereby covenants and agrees to give notice to the Agent of any change in the
Debt Rating or if the Borrower ceases to have a Debt Rating, promptly upon becoming aware of such
change. For certainty, the change in Applicable Pricing Rate shall, subject to Section 7.7(1)(a),
be effective from the date of the change in the Debt Rating regardless of the date notice thereof
is given by the Borrower to the Agent.

	 	 	 	The Borrower shall, and shall cause each of the Material Subsidiaries to, keep
proper books of account and records covering all its business and affairs on a
current basis, make full, true and correct entries in all material respects of their
transactions in such books, set aside on their books from their earnings all such
proper reserves as required by GAAP and permit representatives of the Agent to
inspect such books of account, records and documents and to make copies therefrom
during reasonable business hours and upon reasonable notice and to discuss the
affairs, finances and accounts of the Companies with the officers of the Companies
and their auditors during reasonable business hours and upon reasonable notice;
provided, however, that absent an Event of Default which is then continuing, all but
one such inspection in any 12 month period shall be at the Agent’s expense.
	 
	 	(k)	 	Environmental Matters.
	 
	 	 	 	The Borrower shall, as soon as practicable and in any event within 30 days, notify
the Agent and provide copies upon receipt of all written claims, complaints, notices
or inquiries from a Governmental Authority relating to the condition of the
facilities and properties of the Companies or compliance with Environmental Laws,
which claims, complaints, notices or inquiries relate to matters which would have,
or may reasonably be expected to have, a Material Adverse Effect, and shall, and
shall cause each of the Subsidiaries to, proceed diligently to resolve any such
claims, complaints, notices or inquiries relating to compliance with Environmental
Laws and provide such information and certifications which the Agent may reasonably
request from time to time to evidence compliance with this provision.

	 	(l)	 	Notice of Default or Event of Default.
	 
	 	 	 	Upon the occurrence of a Default or an Event of Default, the Borrower shall promptly
deliver to the Agent a notice specifying the nature and date of occurrence of such
Default or Event of Default and the action which the Borrower proposes to take with
respect thereto.
	 
	 	(m)	 	Ranking of Obligations.
	 
	 	 	 	The Borrower shall at all times ensure that the Obligations rank at least pari passu
with the most senior unsecured, unsubordinated Debt of the Borrower.

9.2 Negative Covenants of the Borrower

          So long as any Obligation is outstanding or the Credit Facility is available hereunder, the
Borrower covenants and agrees with each of the Lenders and the Agent that, unless (subject to
Section 14.10) the Majority of the Lenders otherwise consent in writing:

	 	(a)	 	Encumbrances.
	 
	 	 	 	The Borrower shall not, and shall not suffer or permit any of the Subsidiaries to,
enter into or grant, create, assume or suffer to exist any Lien affecting any of its
property, assets or undertaking, save and except only for the Permitted Liens.
	 
	 	(b)	 	Corporate Existence.
	 
	 	 	 	The Borrower shall not change its jurisdiction of continuation or incorporation.
The Borrower shall not, and shall not suffer or permit any of the Material
Subsidiaries to, take part in any amalgamation, merger, winding-up, dissolution,
capital or corporate reorganization or similar proceeding or arrangement, except
that: (i) any of them may amalgamate or merge with any Subsidiary which is a direct
or indirect Wholly-Owned Subsidiary of the Borrower, (ii) any Material Subsidiary
may wind up into any other Subsidiary or the Borrower if it is a direct Wholly-Owned
Subsidiary of the entity or entities into which it is winding up, (iii) any of them
may transfer any or all of its assets to any Subsidiary which is a direct or
indirect Wholly-Owned Subsidiary of the Borrower, and (iv) the Borrower or any
Material Subsidiary may merge or amalgamate with any other person (other than as
contemplated in subclauses (i) through (iii), inclusive, of this Section 9.2(b)
above) so long as the Borrower or such Material Subsidiary is the surviving entity
of such merger or amalgamation; provided that:

	 	(A)	 	in each case, no Default and no Event of
Default shall have occurred and be continuing, or will occur as a
result of such transaction, or shall exist immediately after the
consummation of such transaction; and
	 
	 	(B)	 	in each case, where the transaction involves
the Borrower, the Borrower, surviving entity or other successor thereto
(each, a “Successor”) shall have executed and delivered or caused to be
executed and delivered to the Agent such instruments and shall have
done or caused to be done such things as, in the reasonable opinion of
Lenders’ Counsel, are necessary or advisable to establish that upon the
consummation of such transaction: (I) the Successor will have assumed
all the covenants and obligations of the Borrower under this Agreement and the other
Documents and (II) this Agreement and the other Documents, as the
case may be, will be valid and binding obligations of the Successor,
entitling the Lenders and the Agent, as against the Successor, to
exercise all their respective rights under this 

 

-46-

	 	 	 	Agreement and the other Documents to the same extent that the Lenders and the Agent
were entitled to exercise such rights against the Borrower prior to
such transaction.

	 	(c)	 	Change in Operations.
	 
	 	 	 	The Borrower shall not materially change the nature or conduct of its consolidated
operations as carried on as at the date hereof.
	 
	 	(d)	 	Disposition of Assets.
	 
	 	 	 	During any Fiscal Year, the aggregate net book value of the assets disposed of by
the Companies (including any disposition by reason of an expropriation of such
assets but excluding any disposition of inventory in the ordinary course of
business, any disposition of obsolete, unusable or redundant assets or any
disposition to the Borrower or any Subsidiary) shall not exceed 25% of Total Assets
as at the last day of the immediately preceding Fiscal Year. Notwithstanding the
foregoing but for greater certainty, the disposition of assets as a result of the
securitization of assets shall only be included in the foregoing calculation if the
assets are transferred to create a securitized asset pool or to increase the overall
size of a securitized asset pool but not if the assets are transferred to replenish
a depleting securitized asset pool.
	 
	 	(e)	 	Debt of Subsidiaries.
	 
	 	 	 	Debt of Subsidiaries shall not at any time exceed U.S. $650,000,000 in the aggregate.

9.3 Agent May Perform Covenants

          If the Borrower fails to perform any covenants on its part herein contained, subject to any
consents or notice or cure periods required by Section 10.1, the Agent may give notice to the
Borrower of such failure and if such covenant remains unperformed, the Agent may, in its discretion
but need not, perform any such covenant capable of being performed by the Agent and if the covenant
requires the payment or expenditure of money, the Agent may, upon having received approval of all
Lenders, make such payments or expenditure and all sums so expended shall be forthwith payable by
the Borrower to the Agent on behalf of the Lenders and shall bear interest at the applicable
interest rate provided in Section 5.8 for amounts due in Canadian Dollars or United States Dollars,
as the case may be. No such performance, payment or expenditure by the Agent shall be deemed to
relieve the Borrower of any default hereunder or under the other Documents.

$40,000,000 or the Equivalent Amount thereof in United States Dollars or the equivalent
thereof in any other currency which is payable on demand is not paid on demand;
	 
	 	(l)	 	this Agreement is determined by a court of competent jurisdiction not to be
valid and enforceable by the Agent and the Lenders against the Borrower, and this
Agreement has not been replaced by a valid and enforceable document which is prepared
by the Agent and presented to the Borrower and is equivalent in effect and commercial
terms (where possible) to this Agreement (other than its; validity and enforceability)
and is executed and delivered by the Borrower within thirty days following such
presentment;
	 
	 	(m)	 	any ERISA Affiliate shall fail to pay when due an amount or amounts aggregating
in excess of the Equivalent Amount in United States Dollars of Cdn. $40,000,000 (or the

thereof in any other currency); or
	 
	 	(n)	 	any person alone or acting jointly in concert with any other person shall own
more than one-half of the outstanding voting securities of the Borrower.

10.2 Acceleration

          If any Event of Default shall occur and for so long as it is continuing:

	 	(a)	 	the entire principal amount of all Loans then outstanding and all accrued and
unpaid interest thereon,

 

-49-

	 	(b)	 	an amount equal to the aggregate face amount at maturity of all Bankers’
Acceptances issued by the Borrower which are unmatured, and
	 
	 	(c)	 	all other Obligations outstanding hereunder,

shall, at the option of the Agent in accordance with Section 13.11 or upon the request of the
Majority of the Lenders, become immediately due and payable upon written notice to that effect from
the Agent to the Borrower, all without any other notice and without presentment, protest, demand,
notice of dishonour or any other demand whatsoever (all of which are hereby expressly waived by the
Borrower). In such event and if the Borrower does not immediately pay all such amounts upon
receipt of such notice, either the Lenders (in accordance with the proviso in Section 13.11(a)) or
the Agent on their behalf may, in their discretion, exercise any right or recourse and/or proceed
by any action, suit, remedy or proceeding against the Borrower authorized or permitted by law for
the recovery of all the indebtedness and liabilities of the Borrower to the Lenders and proceed to
exercise any and all rights hereunder and under the other Documents and no such remedy for the
enforcement of the rights of the Lenders shall be exclusive of or dependent on any other remedy but
any one or more of such remedies may from time to time be exercised independently or in
combination.

10.3 Conversion on Default

          Upon the occurrence of an Event of Default in respect of the Borrower, the Agent on behalf of
the Lenders may convert, at the Equivalent Amount, if applicable, a U.S. Base Rate Loan or Libor
Loan owing by the Borrower, to a Canadian Prime Rate Loan. Interest shall accrue on each such
Canadian Prime Rate Loan at the rate specified in Section 5.1 with interest on all overdue interest
at the same rate, such interest to be calculated daily and payable on demand.

10.4 Remedies Cumulative and Waivers

          For greater certainty, it is expressly understood and agreed that the rights and remedies of
the Lenders and the Agent hereunder or under any other Document are cumulative and are in addition
to and not in substitution for any rights or remedies provided by law or by equity; and any single
or partial exercise by the Lenders or by the Agent of any right or remedy for a default or breach
of any term, covenant, condition or agreement contained in this Agreement or other Document shall
not be deemed to be a waiver of or to alter, affect or prejudice any other right or remedy or other
rights or remedies to which any one or more of the Lenders and the Agent may be lawfully entitled
for such default or breach. Any waiver by, as applicable, the Majority of the Lenders, the Lenders
or the Agent of the strict observance, performance or compliance with any term, covenant, condition
or other matter contained herein and any indulgence granted, either expressly or by course of
conduct, by, as applicable, the Majority of the Lenders, the Lenders or the Agent shall be
effective only in the specific instance and for the purpose for which it was given and shall be
deemed not to be a waiver of any rights and remedies of the Lenders or the Agent under this
Agreement or any other Document as a result of any other default or breach hereunder or thereunder.

10.5 Termination of Lenders’ Obligations

          The occurrence and continuance of a Default or an Event of Default shall relieve the Lenders
of all obligations to provide any further Drawdowns, Rollovers or Conversions to the Borrower
hereunder; provided that the foregoing shall not prevent the Lenders or the Agent from disbursing
money or effecting any Conversion which, by the terms hereof, they are entitled to effect, or any
Conversion or Rollover requested by the Borrower and acceptable to all of the Lenders and the
Agent.

ARTICLE 11

CHANGE OF CIRCUMSTANCES

11.1 Market Disruption Respecting Libor Loans

          In the event that at any time subsequent to the giving of a Drawdown Notice, Rollover Notice
or Conversion Notice to the Agent by the Borrower with regard to any requested Libor Loan, but
before 2:00 p.m. (Toronto time) on the third Banking Day prior to the date of the requested
Drawdown, Rollover or Conversion, as the case may be, a Lender (acting reasonably) makes a
determination, which shall be conclusive and binding upon the Borrower, that:

	 	(a)	 	by reason of circumstances affecting the London interbank market, adequate and
fair means do not exist for ascertaining the rate of interest with respect to, or
deposits are not available in sufficient amounts in the ordinary course of business at
the rate determined hereunder to fund, a requested Libor Loan during the ensuing
Interest Period selected;
	 
	 	(b)	 	the making or continuing of the requested Libor Loan by such Lender has been
made impracticable by the occurrence of an event which materially adversely affects the
London interbank market generally; or
	 
	 	(c)	 	the Libor Rate will not or does not represent the effective cost to such Lender
of United States Dollar deposits in such market for the relevant Interest Period,

then such Lender shall give notice thereof to the Agent and the Borrower as soon as possible after
such determination, but in any event before the aforementioned time, (and the Agent shall, in turn,
give notice thereof to the other Lenders) and the Borrower shall, within one Banking Day after
receipt of such notice and in replacement of the Drawdown Notice, Rollover Notice or Conversion
Notice, as the case may be, previously given by the Borrower, give the Agent a Drawdown Notice or a
Conversion Notice, as the case may be, which specifies the Drawdown of any other Loan or the
Conversion of the relevant Libor Loan on the last day of the applicable Interest Period into any
other Loan which would not be affected by the notice from such Lender pursuant to this Section
11.1. In the event the Borrower fails to give, if applicable, a valid replacement Conversion
Notice with respect to the maturing Libor Loans which were the subject of a Rollover Notice, such
maturing Libor Loans shall be converted on the last day of the applicable Interest Period into U.S.
Base Rate Loans as if a Conversion Notice had been given to the Agent by the Borrower pursuant to
the provisions hereof. In the event the Borrower fails to give, if applicable, a valid replacement
Drawdown Notice with respect to a Drawdown originally requested by way of a Libor Loan, then the
Borrower shall be deemed to have requested a Drawdown by way of a U.S. Base Rate Loan in the amount
specified in the original Drawdown Notice and, on the originally requested Drawdown Date, the
Lenders (subject to the other provisions hereof) shall make available the requested amount by way
of a U.S. Base Rate Loan.

11.2 Market Disruption Respecting Bankers’ Acceptances

          If:

	 	(a)	 	the Agent (acting reasonably) makes a determination, which determination shall
be conclusive and binding upon the Borrower, and notifies the Borrower, that there no
longer exists an active market for bankers’ acceptances accepted by the Lenders; or
	 
	 	(b)	 	the Agent is advised by Lenders holding at least 20% of the Commitments of all
Lenders hereunder by written notice (each, a “Lender BA Suspension Notice”) that such
Lenders have determined (acting reasonably) that the BA Discount Rate will not or does
not accurately reflect the cost of

 

-51-

funds of such Lenders or the discount rate which would be applicable to a sale of
Bankers’ Acceptances accepted by such Lenders in the market;

then:

	 	(c)	 	the right of the Borrower to request Bankers’ Acceptances or BA Equivalent
Advances from any Lender shall be suspended until the Agent determines that the
circumstances causing such suspension no longer exist, and so notifies the Borrower and
the Lenders;
	 
	 	(d)	 	any outstanding Drawdown Notice requesting a Loan by way of Bankers’
Acceptances or BA Equivalent Advances shall be deemed to be a Drawdown Notice
requesting a Loan by way of Canadian Prime Rate Loans in the amount specified in the
original Drawdown Notice;
	 
	 	(e)	 	any outstanding Conversion Notice requesting a Conversion of a Loan by way of
U.S. Base Rate Loans or Libor Loans into a Loan by way of Bankers’ Acceptances or BA
Equivalent Advances shall be deemed to be a Conversion Notice requesting a Conversion
of such Loan into a Loan by way of Canadian Prime Rate Loans; and
	 
	 	(f)	 	any outstanding Rollover Notice requesting a Rollover of a Loan by way of
Bankers’ Acceptances or BA Equivalent Advances, shall be deemed to be a Conversion
Notice requesting a Conversion of such Loans into a Loan by way of Canadian Prime Rate
Loans.

The Agent shall promptly notify the Borrower and the Lenders of any suspension of the Borrower’s
right to request the Bankers’ Acceptances or BA Equivalent Advances and of any termination of any
such suspension. A Lender BA Suspension Notice shall be effective upon receipt of the same by the
Agent if received prior to 2:00 p.m. (Toronto time) on a Banking Day and if not, then on the next
following Banking Day, except in connection with a Drawdown Notice, Conversion Notice or Rollover
Notice previously received by the Agent, in which case the applicable Lender BA Suspension Notice
shall only be effective with respect to such previously received Drawdown Notice, Conversion Notice
or Rollover Notice if received by the Agent prior to 2:00 p.m. (Toronto time) two Banking Days
prior to the proposed Drawdown Date, Conversion Date or Rollover Date (as applicable) applicable to
such previously received Drawdown Notice, Conversion Notice or Rollover Notice, as applicable.

11.3 Change in Law

     (1) If the adoption of any applicable law, regulation, treaty or official directive (whether
or not having the force of law) or any change therein or in the interpretation or application
thereof by any court or by any Governmental Authority or any other entity charged with the
interpretation or administration thereof or compliance by a Lender with any request or direction
(whether or not having the force of law) of any such court, Governmental Authority or other entity
in each case after the date hereof:

	 	(a)	 	subjects such Lender to, or causes the withdrawal or termination of a
previously granted exemption with respect to, any Taxes (other than Taxes on such
Lender’s overall income or capital), or changes the basis of taxation of payments due
to such Lender, or increases any existing Taxes (other than Taxes on such Lender’s
overall income or capital) on payments of principal, interest or other amounts payable
by the Borrower to such Lender under this Agreement;
	 
	 	(b)	 	imposes, modifies or deems applicable any reserve, liquidity, special deposit,
regulatory or similar requirement against assets or liabilities held by, or deposits in
or for the account of, or loans by such Lender, or any acquisition of funds for loans
or commitments to fund loans or obligations in respect of undrawn, committed lines of
credit or in respect of Bankers’ Acceptances accepted by such Lender;

 

-52-

	 	(c)	 	imposes on such Lender or requires there to be maintained by such Lender any
capital adequacy or additional capital requirements (including, without limitation, a
requirement which affects such Lender’s allocation of capital resources to its
obligations) in respect of any Loan or obligation of such Lender hereunder, or any
other condition with respect to this Agreement; or
	 
	 	(d)	 	directly or indirectly affects the cost to such Lender of making available,
funding or maintaining any Loan (other than changes in Taxes on such Lender’s overall
income) or otherwise imposes on such Lender any other condition or requirement
affecting this Agreement or any Loan or any obligation of such Lender hereunder;

and the result of (a), (b), (c) or (d) above, in the sole determination of such Lender acting in
good faith, is:

	 	(e)	 	to increase the cost to such Lender of performing its obligations hereunder
with respect to any Loan;
	 
	 	(f)	 	to reduce any amount received or receivable by such Lender hereunder or its
effective return hereunder or on its capital in respect of any Loan or the Credit
Facility;
	 
	 	(g)	 	to reduce the standby fees payable to such Lender pursuant to Section 5.6; or
	 
	 	(h)	 	to cause such Lender to make any payment with respect to or to forego any
return on or calculated by reference to, any amount received or receivable by such
Lender hereunder with respect to any Loan or the Credit Facility;

such Lender shall determine that amount of money which shall compensate the Lender for such
increase in cost, payments to be made or reduction in income or return or interest foregone (herein
referred to as “Additional Compensation”). Upon a Lender having determined that it is entitled to
Additional Compensation in accordance with the provisions of this Section, such Lender shall
promptly so notify the Borrower and the Agent. The relevant Lender shall provide the Borrower and
the Agent with a photocopy of the relevant law, rule, guideline, regulation, treaty or official
directive (or, if it is impracticable to provide a photocopy, a written summary of the same) and a
certificate of a duly authorized officer of such Lender setting forth the Additional Compensation
and the basis of calculation therefor, which shall be conclusive evidence of such Additional
Compensation in the absence of manifest error. The Borrower shall pay to such Lender within 10
Banking Days of the giving of such notice such Lender’s Additional Compensation. Each of the
Lenders shall be entitled to be paid such Additional Compensation from time to time to the extent
that the provisions of this Section are then applicable notwithstanding that any Lender has
previously been paid any Additional Compensation.

     (2) Each Lender agrees that it will not claim Additional Compensation from the Borrower under
Section 11.3(1):

	 	(a)	 	if it is not generally claiming similar compensation from its other customers
in similar circumstances; or
	 
	 	(b)	 	in respect of any period greater than 9 months prior to the delivery of notice
in respect thereof by such Lender, unless the adoption, change or other event or
circumstance giving rise to the claim for Additional Compensation is retroactive or is
retroactive in effect.

11.4 Prepayment of Portion

          In addition to the other rights and options of the Borrower hereunder and notwithstanding any
contrary provisions hereof, if a Lender gives the notice provided for in Section 11.3 with respect
to any Loan (an “Affected Loan”), the Borrower may, upon 2 Banking Days notice to that effect given
to such Lender and the

 

-53-

Agent (which notice shall be irrevocable), prepay in full without penalty such Lender’s
Rateable Portion of the Affected Loan outstanding together with accrued and unpaid interest on the
principal amount so prepaid up to the date of such prepayment, such Additional Compensation as may
be applicable to the date of such payment and all costs, losses and expenses incurred by such
Lender by reason of the liquidation or re-deployment of deposits or other funds or for any other
reason whatsoever resulting from the repayment of such Affected Loan or any part thereof on other
than the last day of the applicable Interest Period, and upon such payment being made that Lender’s
obligations to make such Affected Loans to the Borrower under this Agreement shall terminate.

11.5 Illegality

          If a Lender determines, in good faith, that the adoption of any applicable law, regulation,
treaty or official directive (whether or not having the force of law) or any change therein or in
the interpretation or application thereof by any court or by any Governmental Authority or any
other entity charged with the interpretation or administration thereof or compliance by a Lender
with any request or direction (whether or not having the force of law) of any such court,
Governmental Authority or other entity, now or hereafter makes it unlawful or impossible for any
Lender to make, fund or maintain a Loan under the Credit Facility or to give effect to its
obligations in respect of such a Loan, such Lender may, by written notice thereof to the Borrower
and to the Agent declare its obligations under this Agreement in respect of such Loan to be
terminated whereupon the same shall forthwith terminate, and the Borrower shall, within the time
required by such law (or at the end of such longer period as such Lender at its discretion has
agreed), either effect a Conversion of such Loan in accordance with the provisions hereof (if such
Conversion would resolve the unlawfulness or impossibility) or prepay the principal of such Loan
together with accrued interest, such Additional Compensation as may be applicable with respect to
such Loan to the date of such payment and all costs, losses and expenses incurred by the Lender by
reason of the liquidation or re-deployment of deposits or other funds or for any other reason
whatsoever resulting from the repayment of such Loan or any part thereof on other than the last day
of the applicable Interest Period. If any such change shall only affect a portion of such Lender’s
obligations under this Agreement which is, in the opinion of such Lender and the Agent, severable
from the remainder of this Agreement so that the remainder of this Agreement may be continued in
full force and effect without otherwise affecting any of the obligations of the Agent, the other
Lenders or the Borrower hereunder, such Lender shall only declare its obligations under that
portion so terminated.

the Borrower hereunder for overdue amounts);
	 
	 	(d)	 	the Borrower’s repayment or prepayment of a Libor Loan otherwise than on the

12.3 Judgment Currency

     (1) If for the purpose of obtaining or enforcing judgment against the Borrower in any court in
any jurisdiction, it becomes necessary to convert into any other currency (such other currency
being hereinafter in this Section referred to as the “Judgment Currency”) an amount due in Canadian
Dollars or United States Dollars under this Agreement, the conversion shall be made at the rate of
exchange prevailing on the Banking Day immediately preceding:

	 	(a)	 	the date of actual payment of the amount due, in the case of any proceeding in
the courts of any jurisdiction that will give effect to such conversion being made on
such date; or
	 
	 	(b)	 	the date on which the judgment is given, in the case of any proceeding in the
courts of any other jurisdiction (the date as of which such conversion is made pursuant
to this Section being hereinafter in this Section referred to as the “Judgment
Conversion Date”).

     (2) If, in the case of any proceeding in the court of any jurisdiction referred to in Section
12.3(1)(b), there is a change in the rate of exchange prevailing between the Judgment Conversion
Date and the date of actual payment of the amount due, the Borrower shall pay such additional
amount (if any) as may be necessary to ensure that the amount paid in the Judgment Currency, when
converted at the rate of exchange prevailing on the date of payment, will produce the amount of
Canadian Dollars or United States Dollars, as the case may be, which could have been purchased with
the amount of Judgment Currency stipulated in the judgment or judicial order at the rate of
exchange prevailing on the Judgment Conversion Date.

     (3) Any amount due from the Borrower under the provisions of Section 12.3(2) shall be due as a
separate debt and shall not be affected by judgment being obtained for any other amounts due under
or in respect of this Agreement.

     (4) The term “rate of exchange” in this Section 12.3 means the noon rate of exchange for
Canadian interbank transactions in Canadian Dollars or United States Dollars, as the case may be,
in the Judgment Currency published by the Bank of Canada for the day in question, or if such rate
is not so published by the Bank of Canada, such term shall mean the Equivalent Amount of the
Judgment Currency.

12.4 Limits on Liability of Indemnified Parties

          No Indemnified Party shall have any liability to the Borrower, any Subsidiary or any person
asserting claims on behalf of, or in right of, the Borrower or any Subsidiary thereof in connection
with or as a result of the Credit Facility, this Agreement or any other Documents or any
transaction contemplated hereby or thereby, except to the extent (and only to the extent) that any
losses, claims, damages, liabilities or expenses incurred by the Borrower, such Subsidiary or other
person are determined by a final non-appealable judgment of a court of competent jurisdiction to
have (a) resulted solely by reason of the gross negligence or wilful misconduct of such Indemnified
Party or (b) in respect only of a Lender, resulted from the intentional failure of such Lender to
advance funds under its Commitment when all conditions precedent to a Drawdown have been satisfied.
In any event, and notwithstanding the foregoing or any other provision hereof or of the other
Documents to the contrary, no Indemnified Party shall be liable for any special, indirect,
consequential or punitive damages in connection with or as a result of the Credit Facility, this
Agreement or any other Document or any transaction contemplated hereby or thereby.

ARTICLE 13

THE AGENT AND ADMINISTRATION OF THE CREDIT FACILITY

13.1 Authorization and Action

     (1) Each Lender hereby irrevocably appoints and authorizes the Agent to be its agent in its
name and on its behalf to exercise such rights or powers granted to the Agent or the Lenders under
this Agreement to the extent specifically provided herein and on the terms hereof, together with
such powers as are reasonably incidental thereto and the Agent hereby accepts such appointment and
authorization. As to any matters not expressly provided for by this Agreement, the Agent shall not
be required to exercise any discretion or take any action, but, subject to Section 14.10, shall be
required to act or to refrain from acting (and shall be fully protected in so acting or refraining
from acting) upon the instructions of the Majority of the Lenders and such instructions shall be
binding upon all Lenders; provided, however, that the Agent shall not be required to take any
action which exposes the Agent to liability in such capacity or which could result in the Agent’s
incurring any costs and expenses, without provision being made for indemnity of the Agent by the
Lenders against any loss, liability, cost or expense incurred, or to be incurred or which is
contrary to this Agreement or applicable law.

     (2) The Lenders agree that all decisions as to actions to be or not to be taken, as to
consents or waivers to be given or not to be given, as to determinations to be made and otherwise
in connection with this Agreement and the Documents, shall be made upon the decision of the
Majority of the Lenders except in respect of a decision or determination where it is specifically
provided in this Agreement that “all of the Lenders” or “the Lenders” or words to similar effect,
or the Agent alone, is to be responsible for same. Each of the Lenders shall be bound by and
agrees to abide by and adopt all decisions made as aforesaid and covenants in all communications
with the Borrower to act in concert and to join in the action, consent, waiver, determination or
other matter decided as aforesaid.

13.2 Procedure for Making Loans

     (1) The Agent shall make Loans available to the Borrower as required hereunder by debiting the
account of the Agent to which the Lenders’ Rateable Portions of such Loans have been credited in
accordance with Section 2.12 (or causing such account to be debited) and, in the absence of other
arrangements agreed to by the Agent and the Borrower in writing, by crediting the United States
Dollar or Canadian Dollar account of the Borrower, as applicable, at the Agent or, at the expense
of the Borrower, transferring (or causing to be transferred) like funds in accordance with the
instructions of the Borrower as set forth in the Drawdown Notice, Rollover Notice or Conversion
Notice, as the case may be, in respect of each Loan; provided that the obligation of the Agent
hereunder to effect such a transfer shall be limited to taking such steps as are commercially
reasonable to implement such instructions, which steps once taken shall constitute conclusive and
binding evidence that such funds were advanced hereunder in accordance with the provisions relating
thereto and the Agent shall not be liable for any damages, claims or costs which may be suffered by
the Borrower and occasioned by the failure of such Loan to reach the designated destination.

     (2) Unless the Agent has been notified by a Lender at least one Banking Day prior to the
Drawdown Date, Rollover Date or Conversion Date, as the case may be, requested by the Borrower that
such Lender will not make available to the Agent its Rateable Portion of such Loan, the Agent may
assume that such Lender has made or will make such portion of the Loan available to the Agent on
the Drawdown Date, Rollover Date or Conversion Date, as the case may be, in accordance with the
provisions hereof and the Agent may, but shall be in no way obligated to, in reliance upon such
assumption, make available to the Borrower on such date a corresponding amount. If and to the
extent such Lender shall not have so made its Rateable Portion of a Loan available to the Agent,
such Lender agrees to pay to the Agent forthwith on demand such Lender’s Rateable Portion of the
Loan and all reasonable costs and expenses incurred by the Agent in connection therewith together
with interest thereon (at the rate payable hereunder by the Borrower in respect of such Loan or, in
the case of funds made available in

 

-57-

anticipation of a Lender remitting proceeds of a Bankers’ Acceptance, at the rate of interest
per annum applicable to Canadian Prime Rate Loans) for each day from the date such amount is made
available to the Borrower until the date such amount is paid to the Agent; provided, however, that
notwithstanding such obligation if such Lender fails to so pay, the Borrower covenants and agrees
that, without prejudice to any rights the Borrower may have against such Lender, it shall repay
such amount to the Agent forthwith after demand therefor by the Agent. The amount payable to the
Agent pursuant hereto shall be set forth in a certificate delivered by the Agent to such Lender and
the Borrower (which certificate shall contain reasonable details of how the amount payable is
calculated) and shall be conclusive and binding evidence thereof in the absence of manifest error.
If such Lender makes the payment to the Agent required herein, the amount so paid shall constitute
such Lender’s Rateable Portion of the Loan for purposes of this Agreement. The failure of any
Lender to make its Rateable Portion of any Loan shall not relieve any other Lender of its
obligation, if any, hereunder to make its Rateable Portion of such Loan on the Drawdown Date,
Rollover Date or Conversion Date, as the case may be; for certainty, without derogating from the
operation of Section 13.14 or Section 14.2, no Lender shall be responsible for the obligations or
any other Lender hereunder.

13.3 Remittance of Payments

          Except for amounts payable to the Agent for its own account, forthwith after receipt of any
repayment pursuant hereto or payment of interest or fees pursuant to Article 5 or payment pursuant
to Article 7, the Agent shall remit to each Lender its Rateable Portion of such payment; provided
that, if the Agent, on the assumption that it will receive on any particular date a payment of
principal, interest or fees hereunder, remits to a Lender its Rateable Portion of such payment and
the Borrower fails to make such payment, each of the Lenders on receipt of such remittance from the
Agent agrees to repay to the Agent forthwith on demand an amount equal to the remittance together
with all reasonable costs and expenses incurred by the Agent in connection therewith and interest
thereon at the rate and calculated in the manner applicable to the Loan in respect of which such
payment is made, or, in the case of a remittance in respect of Bankers’ Acceptances, at the rate of
interest applicable to Canadian Prime Rate Loans for each day from the date such amount is remitted
to the Lenders without prejudice to any right such Lender may have against the Borrower. The exact
amount of the repayment required to be made by the Lenders pursuant hereto shall be as set forth in
a certificate delivered by the Agent to each Lender, which certificate shall be conclusive and
binding for all purposes in the absence of manifest error.

13.4 Redistribution of Payment

          Each Lender agrees that:

	 	(a)	 	if the Lender exercises any security against or right of counter-claim, set off
or banker’s lien or similar right with respect to the property of the Borrower or if
under any applicable bankruptcy, insolvency or other similar law it receives a secured
claim and collateral for which it is, or is entitled to exercise any set-off against, a
debt owed by it to the Borrower, the Lender shall apportion the amount thereof
proportionately between:

	 	(i)	 	such Lender’s Rateable Portion of all outstanding Obligations
owing by the Borrower (including the face amounts at maturity of Bankers’
Acceptances accepted by the Lenders), which amounts shall be applied in
accordance with Section 13.4(b); and
	 
	 	(ii)	 	amounts otherwise owed to such Lender by the Borrower,

provided that (i) any cash collateral account held by such Lender as collateral for a letter
of credit or bankers’ acceptance (other than a Bankers’ Acceptance) issued or accepted by
such Lender on behalf of the Borrower may be applied by such Lender to such amounts owed by
the Borrower to such Lender pursuant to such letter of credit or in respect of any such
bankers’ acceptance without apportionment and (ii) these provisions do not apply to:

 

-58-

	 	(A)	 	a right or claim which arises or exists in respect
of a loan or other debt in respect of which the relevant Lender holds a
Lien which is a Permitted Encumbrance;
	 
	 	(B)	 	cash collateral provided, or the exercise of rights
of counterclaim, set-off or banker’s lien or similar rights, in respect
of account positioning arrangements for the Borrower and its Subsidiaries
provided by a Lender in the ordinary course of business or in respect of
other cash management services provided by a Lender in the ordinary
course of business;
	 
	 	(C)	 	any reduction in amounts owing to the Borrower or a
Subsidiary upon the termination of Hedging Instruments entered into with
the relevant Lender or its Affiliates; or
	 
	 	(D)	 	any payment to with a Lender is entitled as a
result of any credit derivative or other form of credit protection
obtained by such Lender;

	 	(b)	 	if, in the aforementioned circumstances, the Lender, through the exercise of a
right, or the receipt of a secured claim described in Section 13.4(a) above or
otherwise, receives payment of a proportion of the aggregate amount of Obligations due
to it hereunder which is greater than the proportion received by any other Lender in
respect of the aggregate Obligations due to the Lenders (having regard to the
respective Rateable Portions of the Lenders), the Lender receiving such proportionately
greater payment shall purchase, on a non-recourse basis at par, and make payment for a
participation (which shall be deemed to have been done simultaneously with receipt of
such payment) in the outstanding Loans of the other Lender or Lenders so that their
respective receipts shall be pro rata to their respective Rateable Portions; provided,
however, that if all or part of such proportionately greater payment received by such
purchasing Lender shall be recovered by or on behalf of the Borrower or any trustee,
liquidator, receiver or receiver-manager or person with analogous powers from the
purchasing Lender, such purchase shall be rescinded and the purchase price paid for
such participation shall be returned to the extent of such recovery, but without
interest unless the purchasing Lender is required to pay interest on such amount, in
which case each selling Lender shall reimburse the purchasing Lender pro rata in
relation to the amounts received by it. Such Lender shall exercise its rights in
respect of such secured claim in a manner consistent with the rights of the Lenders
entitled under this Section to share in the benefits of any recovery on such secured
claims; and
	 
	 	(c)	 	if the Lender does, or is required to do, any act or thing permitted by Section
13.4(a) or (b) above, it shall promptly provide full particulars thereof to the Agent.

13.5 Duties and Obligations

          Neither the Agent nor any of its directors, officers, agents or employees (and, for purposes
hereof, the Agent shall be deemed to be contracting as agent and trustee for and on behalf of such
persons) shall be liable to the Lenders for any action taken or omitted to be taken by it or them
under or in connection with this Agreement except for its or their own gross negligence or willful
misconduct. Without limiting the generality of the foregoing, the Agent:

	 	(a)	 	may assume that there has been no assignment or transfer by any means by the
Lenders of their rights hereunder, unless and until the Agent receives written notice
of the assignment thereof from such Lender and the Agent receives from the assignee an
executed Assignment Agreement providing, inter alia, that such assignee is bound hereby
as it would have been if it had been an original Lender party hereto;

 

-59-

	 	(b)	 	may consult with legal counsel (including receiving the opinions of Borrower’s
counsel and Lenders’ Counsel required hereunder), independent public accountants and
other experts selected by it and shall not be liable for any action taken or omitted to
be taken in good faith by it in accordance with the advice of such counsel, accountants
or experts;
	 
	 	(c)	 	shall incur no liability under or in respect of this Agreement by acting upon
any notice, consent, certificate or other instrument or writing (which may be by
telegram, cable, facsimile transmission, electronic mail or other electronic means of
communication which may generate a written record thereof) believed by it to be genuine
and signed or sent by the proper party or parties or by acting upon any representation
or warranty of the Borrower made or deemed to be made hereunder;
	 
	 	(d)	 	may assume that no Default or Event of Default has occurred and is continuing
unless it has actual knowledge to the contrary;
	 
	 	(e)	 	may rely as to any matters of fact which might reasonably be expected to be
within the knowledge of any person upon a certificate signed by or on behalf of such
person;
	 
	 	(f)	 	shall not be bound to disclose to any other person any information relating to
the Borrower, any of its Subsidiaries or any other person if such disclosure would or
might in its opinion constitute a breach of any applicable law, be in default of the
provisions hereof or be otherwise actionable at the suit of any other person; and
	 
	 	(g)	 	may refrain from exercising any right, power or discretion vested in it which
would or might in its reasonable opinion be contrary to any applicable law or any
directive or otherwise render it liable to any person, and may do anything which is in
its reasonable opinion necessary to comply with such applicable law.

Further, the Agent (i) does not make any warranty or representation to any Lender nor shall it be
responsible to any Lender for the accuracy or completeness of the representations and warranties of
the Borrower herein or the data made available to any of the Lenders in connection with the
negotiation of this Agreement, or for any statements, warranties or representations (whether
written or oral) made in or in connection with this Agreement; (ii) shall not have any duty to
ascertain or to enquire as to the performance or observance of any of the terms, covenants or
conditions of this Agreement on the part of the Borrower or to inspect the property (including the
books and records) of the Borrower or any of its Subsidiaries; and (iii) shall not be responsible
to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency
or value of this Agreement or any instrument or document furnished pursuant hereto.

13.6 Prompt Notice to the Lenders

          Notwithstanding any other provision herein, the Agent agrees to provide to the Lenders, with
copies where appropriate, all information, notices and reports required to be given to the Agent by
the Borrower, promptly upon receipt of same, excepting therefrom information and notices relating
solely to the role of Agent hereunder.

13.7 Agent’s and Lenders’ Authorities

          With respect to its Commitment and the Drawdowns, Rollovers, Conversions and Loans made by it
as a Lender, the Agent shall have the same rights and powers under this Agreement as any other
Lender and may exercise the same as though it were not the Agent. Subject to the express
provisions hereof relating to the rights and obligations of the Agent and the Lenders in such
capacities, the Agent and each Lender may accept deposits from, lend money to, and generally engage
in any kind of business with the Borrower and its Subsidiaries or any

 

-60-

corporation or other entity owned or controlled by any of them and any person which may do
business with any of them without any duties to account therefor to the Agent or the other Lenders
and, in the case of the Agent, all as if it was not the Agent hereunder.

13.8 Lender Credit Decision

          It is understood and agreed by each Lender that it has itself been, and will continue to be,
solely responsible for making its own independent appraisal of and investigations into the
financial condition, creditworthiness, condition, affairs, status and nature of the Borrower and
its Subsidiaries. Each Lender represents to the Agent that it is engaged in the business of making
and evaluating the risks associated with commercial revolving or term loans, or both, to
corporations similar to the Borrower, that it can bear the economic risks related to the
transaction contemplated hereby, that it has had access to all information deemed necessary by it
in making such decision (provided that this representation shall not impair its rights against the
Borrower) and that it is entering into this Agreement in the ordinary course of its commercial
lending business. Accordingly, each Lender confirms with the Agent that it has not relied, and
will not hereafter rely, on the Agent (i) to check or enquire on its behalf into the adequacy,
accuracy or completeness of any information provided by the Borrower or any other person under or
in connection with this Agreement or the transactions herein contemplated (whether or not such
information has been or is hereafter distributed to such Lender by the Agent), or (ii) to assess or
keep under review on its behalf the financial condition, creditworthiness, condition, affairs,
status or nature of the Borrower or any of its Subsidiaries. Each Lender acknowledges that a copy
of this Agreement has been made available to it for review and each Lender acknowledges that it is
satisfied with the form and substance of this Agreement. Each Lender hereby covenants and agrees
that, subject to Section 13.4, it will not make any arrangements with the Borrower for the
satisfaction of any Loans or other Obligations without the consent of all the other Lenders.

13.9 Indemnification of Agent

          The Lenders hereby agree to indemnify the Agent (to the extent not reimbursed by the
Borrower), on a pro rata basis in accordance with their respective Commitment as a proportion of
the aggregate of all outstanding Commitments, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted
against the Agent in any way relating to or arising out of this Agreement or any action taken or
omitted by the Agent under or in respect of this Agreement in its capacity as Agent; provided that
no Lender shall be liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs expenses or disbursements resulting from the Agent’s
gross negligence or willful misconduct. If the Borrower subsequently repays all or a portion of
such amounts to the Agent, the Agent shall reimburse the Lenders their pro rata shares (according
to the amounts paid by them in respect thereof) of the amounts received from the Borrower. Without
limiting the generality of the foregoing, each Lender agrees to reimburse the Agent promptly upon
demand for its portion (determined as above) of any out-of-pocket expenses (including counsel fees)
incurred by the Agent in connection with the preservation of any rights of the Agent or the Lenders
under, or the enforcement of, or legal advice in respect of rights or responsibilities under, this
Agreement, to the extent that the Agent is not reimbursed for such expenses by the Borrower.

13.10 Successor Agent

          The Agent may, as hereinafter provided, resign at any time by giving 45 days’ prior written
notice thereof to the Lenders and the Borrower. Upon any such resignation, the Lenders shall,
after soliciting the view of the Borrower, have the right to appoint another Lender as a successor
agent (the “Successor Agent”) who shall be acceptable to the Borrower, acting reasonably. If no
Successor Agent shall have been so appointed by the Lenders and shall have accepted such
appointment within 30 days after the retiring Agent’s giving of notice of resignation, then the
retiring Agent shall, on behalf of the Lenders, appoint a Successor Agent who shall be a Lender
acceptable to the Borrower, acting reasonably. Upon the acceptance of any appointment as Agent
hereunder by a Successor

 

-61-

Agent, such Successor Agent shall thereupon succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Agent, and the retiring Agent shall thereupon be
discharged from its further duties and obligations as Agent under this Agreement. After any
retiring Agent’s resignation hereunder as Agent, the provisions of this Article shall continue to
enure to its benefit as to any actions taken or omitted to be taken by it as Agent or in its
capacity as Agent while it was Agent hereunder.

13.11 Taking and Enforcement of Remedies

          Each of the Lenders hereby acknowledges that, to the extent permitted by applicable law, the
remedies provided hereunder to the Lenders are for the benefit of the Lenders collectively and
acting together and not severally and further acknowledges that its rights hereunder are to be
exercised not severally, but collectively by the Agent upon the decision of the Majority of the
Lenders regardless of whether acceleration was made pursuant to Section 10.2. Notwithstanding any
of the provisions contained herein, each of the Lenders hereby covenants and agrees that it shall
not be entitled to individually take any action with respect to the Credit Facility, including,
without limitation, any acceleration under Section 10.2, but that any such action shall be taken
only by the Agent with the prior written agreement or instructions of the Majority of the Lenders;
provided that, notwithstanding the foregoing, if (a) the Agent, having been adequately indemnified
against costs and expenses of so doing by the Lenders, shall fail to carry out any such
instructions of the Majority of the Lenders, any Lender may do so on behalf of all Lenders and
shall, in so doing, be entitled to the benefit of all protections given the Agent hereunder or
elsewhere, and (b) in the absence of instructions from the Majority of the Lenders and where in the
sole opinion of the Agent the exigencies of the situation warrant such action, the Agent may
without notice to or consent of the Lenders or any of them take such action on behalf of the
Lenders as it deems appropriate or desirable in the interests of the Lenders. Each of the Lenders
hereby further covenants and agrees that upon any such written consent being given by the Majority
of the Lenders, or upon a Lender or the Agent taking action as aforesaid, it shall cooperate fully
with the Lender or the Agent to the extent requested by the Lender or the Agent in the collective
realization including, without limitation, and, if applicable, the appointment of a receiver, or
receiver and manager to act for their collective benefit. Each Lender covenants and agrees to do
all acts and things and to make, execute and deliver all agreements and other instruments,
including, without limitation, any instruments necessary to effect any registrations, so as to
fully carry out the intent and purpose of this Section; and each of the Lenders hereby covenants
and agrees that, subject to Section 5.7, Section 13.4 and Section 9.2(a) it has not heretofore and
shall not seek, take, accept or receive any security for any of the obligations and liabilities of
the Borrower hereunder or under any other document, instrument, writing or agreement ancillary
hereto and shall not enter into any agreement with any of the parties hereto or thereto relating in
any manner whatsoever to the Credit Facility, unless all of the Lenders shall at the same time
obtain the benefit of any such security or agreement.

          With respect to any enforcement, realization or the taking of any rights or remedies to
enforce the rights of the Lenders hereunder, the Agent shall be a trustee for each Lender, and all
monies received from time to time by the Agent in respect of the foregoing shall be held in trust
and shall be trust assets within the meaning of applicable bankruptcy or insolvency legislation and
shall be considered for the purposes of such legislation to be held separate and apart from the
other assets of the Agent, and each Lender shall be entitled to their Rateable Portion of such
monies. In its capacity as trustee, the Agent shall be obliged to exercise only the degree of care
it would exercise in the conduct and management of its own business and in accordance with its
usual practice concurrently employed or hereafter instituted for other substantial commercial
loans.

13.12 Reliance Upon Agent

          The Borrower shall be entitled to rely upon any certificate, notice or other document or other
advice, statement or instruction provided to it by the Agent pursuant to this Agreement, and the
Borrower shall generally be entitled to deal with the Agent with respect to matters under this
Agreement which the Agent is authorized to deal with without any obligation whatsoever to satisfy
itself as to the authority of the Agent to act on behalf of the Lenders and without any liability
whatsoever to the Lenders for relying upon any certificate, notice or

 

-62-

other document or other advice, statement or instruction provided to it by the Agent,
notwithstanding any lack of authority of the Agent to provide the same.

13.13 No Liability of Agent

          The Agent shall have no responsibility or liability to the Borrower on account of the failure
of any Lender to perform its obligations hereunder (unless such failure was caused, in whole or in
part, by the Agent’s failure to observe or perform its obligations hereunder), or to any Lender on
account of the failure of the Borrower or any Lender to perform its obligations hereunder.

13.14 The Agent and Defaulting Lenders

     (1) Each Defaulting Lender shall be required to provide to the Agent cash in an amount, as
shall be determined from time to time by the Agent in its discretion, equal to all obligations of
such Defaulting Lender to the Agent that are owing or may become owing pursuant to this Agreement,
including such Defaulting Lender’s obligation to pay its Rateable Portion of any indemnification or
expense reimbursement amounts not paid by the Borrower. Such cash shall be held by the Agent in
one or more cash collateral accounts, which accounts shall be in the name of the Agent and shall
not be required to be interest bearing. The Agent shall be entitled to apply the foregoing cash in
accordance with Section 13.9.

     (2) In addition to the indemnity and reimbursement obligations noted in Section 13.9, the
Lenders agree to indemnify the Agent (to the extent not reimbursed by the Borrower and without
limiting the obligations of the Borrower hereunder) rateably according to their respective Rateable
Portions (and in calculating the Rateable Portion of a Lender, ignoring the Commitments of
Defaulting Lenders) any amount that a Defaulting Lender fails to pay the Agent and which is due and
owing to the Agent pursuant to Section 13.9. Each Defaulting Lender agrees to indemnify each other
Lender for any amounts paid by such Lender and which would otherwise be payable by the Defaulting
Lender.

     (3) The Agent shall be entitled to set off any Defaulting Lender’s Rateable Portion of all
payments received from the Borrower against such Defaulting Lender’s obligations to fund payments
and Loans required to be made by it and to purchase participations required to be purchased by it
in each case under this Agreement and the other Documents. The Agent shall be entitled to withhold
and deposit in one or more non-interest bearing cash collateral accounts in the name of the Agent
all amounts (whether principal, interest, fees or otherwise) received by the Agent and due to a
Defaulting Lender pursuant to this Agreement, which amounts shall be used by the Agent:

	 	(a)	 	first, to reimburse the Agent for any amounts owing to it by the Defaulting
Lender pursuant to any Document;
	 
	 	(b)	 	second, to repay on a pro rata basis any (i) Loans made by a Lender pursuant to
Section 14.2(4) in order to fund a shortfall created by a Defaulting Lender which
repayment shall be in the form of an assignment by each such Lender of such Loan to the
Defaulting Lender against receipt of such repayment, and (ii) any payments made by a
Lender pursuant to Section 13.14(2) in order to fund a shortfall created by a
Defaulting Lender;
	 
	 	(c)	 	third, to cash collateralize all other obligations of such Defaulting Lender to
the Agent owing pursuant to this Agreement in such amount as shall be determined from
time to time by the Agent in its discretion, including such Defaulting Lender’s
obligation to pay its Rateable Portion of any indemnification or expense reimbursement
amounts not paid by the Borrower; and
	 
	 	(d)	 	fourth, to fund from time to time the Defaulting Lender’s Rateable Portion of
Loans.

 

-63-

     (4) For greater certainty and in addition to the foregoing, neither the Agent nor any of its
Affiliates nor any of their respective shareholders, officers, directors, employees, agents or
representatives shall be liable to any Lender (including, without limitation, a Defaulting Lender)
for any action taken or omitted to be taken by it in connection with amounts payable by the
Borrower to a Defaulting Lender and received and deposited by the Agent in a cash collateral
account and applied in accordance with the provisions of this Agreement, save and except for the
gross negligence or wilful misconduct of the Agent as determined by a final non-appealable
judgement of a court of competent jurisdiction.

13.15 Article for Benefit of Agent and Lenders

          The provisions of this Article 13 which relate to the rights and obligations of the Lenders to
each other or to the rights and obligations between the Agent and the Lenders shall be for the
exclusive benefit of the Agent and the Lenders, and, except to the extent provided in Sections
13.1, 13.2, 13.6, 13.10, 13.11, 13.12, 13.13, 13.14 and this Section 13.15, the Borrower shall not
have any rights or obligations thereunder or be entitled to rely for any purpose upon such
provisions. Any Lender may waive in writing any right or rights which it may have against the
Agent or the other Lenders hereunder without the consent of or notice to the Borrower.

ARTICLE 14

GENERAL

14.1 Exchange and Confidentiality of Information

     (1) The Borrower agrees that the Agent and each Lender may provide any assignee or participant
or any bona fide prospective assignee or participant pursuant to Sections 14.6 or 14.7 with any
information concerning the financial condition of the Borrower and its Subsidiaries provided such
party agrees in writing with the Agent or such Lender for the benefit of the Borrower to be bound
by a like duty of confidentiality to that contained in this Section.

     (2) Each of the Agent and the Lenders acknowledges the confidential nature of the financial,
operational and other information and data provided and to be provided to them by the Borrower
pursuant hereto (the “Information”) and agrees to prevent the disclosure thereof provided, however,
that:

	 	(a)	 	the Agent and the Lenders may disclose all or any part of the Information if,
in their reasonable opinion, such disclosure is required: (i) by their respective
auditors, or (ii) in connection with any actual or threatened judicial, administrative
or governmental proceedings (including proceedings initiated under or in respect of
this Agreement or upon the request of its independent auditors or a Governmental
Authority having jurisdiction over it);
	 
	 	(b)	 	the Agent and the Lenders shall incur no liability in respect of any
Information required to be disclosed by any applicable law, or by applicable treaty,
order, policy or directive having the force of law, to the extent of such requirement;
	 
	 	(c)	 	the Agent and the Lenders may provide Lenders’ Counsel and their other agents
and professional advisors with any Information; provided that such persons shall be
under a like duty of confidentiality to that contained in this Section 14.1;
	 
	 	(d)	 	the Agent and each of the Lenders shall incur no liability in respect of any
Information: (i) which is or becomes readily available to the public (other than by a
breach hereof) or which has been made readily available to the public by the Borrower
or its Subsidiaries, (ii) which the Agent or the relevant Lender can show was, prior to receipt thereof from the Borrower, lawfully in
the Agent’s or Lender’s possession and not then subject to any obligation on its part
to the Borrower to 

 

-64-

	 	 	 	maintain confidentiality, or (iii) which the Agent or the relevant
Lender received from a third party who was not, to the knowledge of the Agent or such
Lender, under a duty of confidentiality to the Borrower at the time the information
was so received;
	 
	 	(e)	 	the Agent and the Lenders may disclose the Information to other financial
institutions and other persons in connection with the assignment by a Lender of the
Credit Facility or the granting by a Lender of a participation in the Credit Facility
where such financial institution or other person agrees to be under a like duty of
confidentiality to that contained in this Section; and
	 
	 	(f)	 	the Agent and the Lenders may disclose all or any part of the Information so as
to enable the Agent and the Lenders to initiate any lawsuit against the Borrower or to
defend any lawsuit commenced by the Borrower the issues of which touch on the
Information, but only to the extent such disclosure is necessary to the initiation or
defense of such lawsuit.

14.2 Nature of Obligation under this Agreement; Defaulting Lenders

     (1) The obligations of each Lender and of the Agent under this Agreement are several. The
failure of any Lender to carry out its obligations hereunder shall not relieve the other Lenders,
the Agent or the Borrower of any of their respective obligations hereunder.

     (2) Without derogating from the operation of Section 13.14 and this Section 14.2, neither the
Agent nor any Lender shall be responsible for the obligations of any other Lender hereunder.

     (3) Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a
Defaulting Lender, then the following provisions shall apply for so long as such Lender is a
Defaulting Lender:

	 	(a)	 	the standby fees payable pursuant to Section 5.6 shall cease to accrue on the
unused portion of the Commitment of such Defaulting Lender;
	 
	 	(b)	 	a Defaulting Lender shall not be included in determining whether, and the
Commitment and the Rateable Portion of the Outstanding Principal of such Defaulting
Lender shall not be included in determining whether, all Lenders or the Majority of the
Lenders have taken or may take any action hereunder (including any consent to any
amendment or waiver pursuant to Section 14.10), provided that any waiver, amendment or
modification requiring the consent of all Lenders or each affected Lender that affects
such Defaulting Lender differently than other affected Lenders shall require the
consent of such Defaulting Lender; and
	 
	 	(c)	 	for the avoidance of doubt, the Borrower shall retain and reserve its other
rights and remedies respecting each Defaulting Lender.

     (4) Should any Lender fail to fund its Rateable Portion of a Loan hereunder, then each other
Lender shall fund a portion of such defaulted amount in an amount equal to such other Lender’s
Rateable Portion (and in calculating the Rateable Portion of a Lender, ignoring the Commitments of
Defaulting Lenders) of such unfunded portion; provided that, for certainty, no Lender shall be
obligated by this Section to make or provide Loans in excess of its Commitment.

     (5) If any Lender shall cease to be a Defaulting Lender, then, upon becoming aware of the
same, the Agent shall notify the other Lenders and (in accordance with the written direction of the
Agent) such Lender (which has ceased to be a Defaulting Lender) shall purchase, and the other
Lenders shall on a rateable basis sell and assign to such Lender, portions of such Loans equal in total to such Lender’s Rateable Portion
thereof without regard to Section 14.2 (4).

          This Agreement shall enure to the benefit of and be binding upon the Borrower, the Lenders,

14.6 Assignment

          Any Lender may, without consent during the continuance of an Event of Default and at all other
times with the prior written consent of each of the Borrower and the Agent, which consents shall
not be unreasonably withheld or delayed, sell, assign, transfer or grant an interest in its
Commitment, its Rateable Portion of the Loans and its rights under the Documents; provided that,
except during the continuance of an Event of Default or except with the consent of the Borrower and
the Agent, such consents not to be unreasonably withheld or delayed, no Lender shall, without the
consent of the Borrower and the Agent, sell, assign, transfer or grant an interest in its
Commitment if the effect of the same would be to have a Lender with a Commitment of less than U.S.
$25,000,000 (such amount to be reduced in proportion to any partial reductions in the Credit
Facility), and further provided that, it shall be a precondition to any such sale, assignment,
transfer or grant that the contemplated assignee Lender shall have paid to the Agent, for the
Agent’s own account, a transfer fee of U.S. $3,500.00. Upon any such sale, assignment, transfer or
grant, the granting Lender shall have no further obligation hereunder with respect to such
interest. Upon any such sale, assignment, transfer or grant, the granting Lender, the new Lender,
the Agent and the Borrower shall execute and deliver an Assignment Agreement. Subject to the

          Any Lender may, without the consent of the Borrower, grant one or more participations in its
Commitment and its Rateable Portion of the Loans to other persons, provided that the granting of
such a participation shall be at the Lender’s own cost and shall not affect the obligations of such
Lender hereunder nor shall it increase the costs to the Borrower hereunder or under any of the
other Documents. No such participant shall by virtue of such participations be party to this
Agreement.

14.8 Severability

          Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall

expressions, (viii) the definition of “Event of Default” or (ix) this Section, shall
require the agreement or waiver of all the Lenders; and
	 
	 	(b)	 	an amendment or waiver which changes or relates to the rights and/or
obligations of the Agent shall also require the agreement of the Agent thereto.

Lenders under any provision of this Agreement must be in writing and may be given subject to any
conditions thought fit by the person giving that waiver or consent. Any waiver or consent shall be
effective only in the instance and for the purpose for which it is given.

Ladies and Gentlemen:

			
	Re:	 	Potash Corporation of Saskatchewan Inc.

     We have acted as Ontario counsel to Potash Corporation of Saskatchewan Inc. (the “Borrower”)
in connection with a credit agreement dated May 29, 2008 as amended and restated pursuant to an
amended and restated credit agreement dated as of January 21, 2009 (such amended and restated
credit agreement, the “Credit Agreement”) among the Borrower, as borrower, The Bank of Nova Scotia,
Royal Bank of Canada, Bank of Montreal, HSBC Bank Canada, Bank of America, N.A., Canada Branch,
Canadian Imperial Bank of Commerce and Export Development Canada, together with such other persons
as become parties thereto, as lenders (collectively, the “Lenders”) and The Bank of Nova Scotia, as
agent of the Lenders (the “Agent”). Our opinion relates to the Credit Agreement as in effect on
the date hereof and does not speak to any expansion of the Credit Facility under Section 2.18 of
the Credit Agreement. Capitalized terms used in this opinion that we do not define have the
meanings given to them in the Credit Agreement.

     This opinion is being provided to you pursuant to Section 3.2(d) of the Credit Agreement. We
have participated in the preparation of and examined an executed copy of the Credit Agreement.

     For the purposes of this opinion, we have also examined originals or copies, certified or
otherwise identified to our satisfaction, and relied upon the following documents (collectively,
the “Corporate Documents”):

	 	(a)	 	the articles of continuance of the Borrower;

	 	(b)	 	the by-laws of the Borrower;

	 	(c)	 	certain resolutions of the Borrower’s directors relating to the Credit
Agreement;

	 	(d)	 	a certificate of compliance provided by governmental authorities of Canada with
respect to the Borrower (the “Certificate of Compliance”); and

 

 

	 	(e)	 	a certificate of an officer of the Borrower (the “Officer’s Certificate”).

     Duplicate copies of the Officer’s Certificate are delivered contemporaneously with this
opinion. Copies of the other Corporate Documents, other than the Certificate of Compliance, are
annexed to the Officer’s Certificate. We have relied upon the Corporate Documents without
independent investigation of the matters provided for in them for the purpose of providing our
opinions expressed below. We have not conducted a review of the minute books of the Borrower.

     In examining all documents and in providing our opinions below we have assumed that:

	 	(a)	 	all individuals had the requisite legal capacity;

	 	(b)	 	all signatures are genuine;

	 	(c)	 	all documents submitted to us as originals are complete and authentic and all
photostatic, certified, telecopied, notarial or other copies conform to the originals;

	 	(d)	 	all facts set forth in the official public records, certificates and documents
supplied by public officials or otherwise conveyed to us by public officials are
complete, true and accurate;

	 	(e)	 	the articles of continuance are conclusive evidence that the Borrower is
incorporated under the Canada Business Corporations Act;

	 	(f)	 	all facts set forth in the certificates supplied by the respective officers and
directors of the Borrower including, without limitation, the Officer’s Certificate are
complete, true and accurate;

	 	(g)	 	the Credit Agreement has been duly authorized, executed and delivered by and is
enforceable in accordance with its terms against each party to it other than the
Borrower; and

	 	(h)	 	performance of the obligations would not be illegal under the law of the place
of performance if that is a place other than Ontario.

     Our opinion below is expressed only with respect to the laws of the province of Ontario (the
“Jurisdiction”) and of the laws of Canada applicable in the Jurisdiction. Any reference to the
laws of the Jurisdiction includes the laws of Canada that apply in the Jurisdiction.

     Our opinion is expressed with respect to the laws of the Jurisdiction in effect on the date of
this opinion and we do not accept any responsibility to take into account or inform the addressees,
or any other person authorized to rely on this opinion, of any changes in law, facts or other
developments subsequent to this date that do or may affect the opinions we express, nor do we have
any obligation to advise you of any other change in any matter addressed in this opinion or to
consider whether it would be appropriate for any other person other than the addressees to rely on
our opinion.

- 2 -

 

          Based on the above, and subject to the qualifications below, we are of the opinion that:

	1.	 	The Borrower (a) is a corporation incorporated and existing under the laws of Canada, and (b)
has the corporate power to enter into and perform its obligations under the Credit Agreement.

	2.	 	The execution and delivery of and performance by the Borrower of the Credit Agreement have
been authorized by all necessary corporate action on the part of the Borrower.

	3.	 	The execution and delivery of and performance by the Borrower of the Credit Agreement does
not constitute or result in a violation or breach of or a default under:

	 	(a)	 	its articles of continuance or by-laws; or

	 	(b)	 	any applicable law in the Jurisdiction.

	4.	 	No authorization, consent or approval of, or filing, registration, qualification or recording
with any Governmental Authority having jurisdiction in the Jurisdiction is required in
connection with the execution and delivery of or performance by the Borrower of the Credit
Agreement, except any continuous disclosure filings required to be made by a reporting issuer
pursuant to applicable securities laws.

	5.	 	The Credit Agreement has been duly executed and delivered by the Borrower.

	6.	 	The Credit Agreement constitutes a legal, valid and binding agreement of the Borrower
enforceable against it in accordance with its terms.

          All of the opinions expressed above are subject to the following qualifications:

	 	(a)	 	the enforceability of the Credit Agreement may be limited by bankruptcy,
winding-up, insolvency, arrangement, fraudulent preference and conveyance, assignment
and preference and other similar laws of general application affecting the enforcement
of creditors’ rights;

	 	(b)	 	a court may exercise discretion in the granting of equitable remedies such as
specific performance and injunction;

	 	(c)	 	the enforceability of the Credit Agreement may be limited by general principles
of law and equity relating to the conduct of the Agent and/or the Lenders prior to
execution of or in the administration or performance of the Credit Agreement,
including, without limitation, (i) estoppel and waiver, (ii) laches, and (iii)
reasonableness and good faith in the exercise of discretionary powers;

	 	(d)	 	the discretion that a court may reserve to itself to decline to hear an action
if it is not the proper forum to hear the action or if concurrent proceedings are being
brought elsewhere;

- 3 -

 

	 	(e)	 	the Currency Act (Canada) precludes a court in Canada from giving judgment in
any currency other than Canadian currency;

	 	(f)	 	a court may decline to accept the factual and legal determinations of a party
notwithstanding that a contract or instrument provides that the determinations of that
party shall be conclusive;

	 	(g)	 	we express no opinion as to the enforceability of any term providing for the
severance of illegal or unenforceable provisions from the remaining provisions of an
agreement;

	 	(h)	 	we express no opinion as to the enforceability of any provision that states
that modifications, amendments or waivers are not binding unless in writing;

	 	(i)	 	we express no opinion as to the enforceability of any provision exculpating any
party from liability in respect of acts or omissions that may be illegal, fraudulent or
involve wilful misconduct or gross negligence;

	 	(j)	 	any provision that provides for interest to be paid at a higher rate after than
before default, that provides for a forfeiture of a deposit or any other property or
that provides for a particular calculation of damages upon breach may not be
enforceable if it is interpreted by a court to be a penalty or if the court determines
that relief from forfeiture is appropriate;

	 	(k)	 	a court may decline to enforce rights of indemnification or contribution to the
extent that they directly or indirectly relate to liabilities imposed by law on the
indemnified party for which it would be contrary to public policy to require
indemnification by the indemnifying party or which relate to liabilities for
non-Canadian taxes;

	 	(l)	 	we express no opinion as to the enforceability of, nor as to the manner in
which a court would interpret and apply, any provision of the Credit Agreement which
refers to, incorporates by reference, or requires compliance with any law, statute,
rule or regulation of any jurisdiction other than the Jurisdiction;

	 	(m)	 	we express no opinion as to the enforceability by or against a person who is
not a party to the Credit Agreement of any provision in the Credit Agreement which
purports to bind or affect or confer a benefit upon that person;

	 	(n)	 	we express no opinion as to the enforceability of any provisions of the Credit
Agreement which require the Borrower to pay or indemnify the Agent or the Lenders for
costs and expenses in connection with judicial proceedings since the recoverability of
such costs and expenses are in the discretion of the court and the court has the
discretion to determine by whom and to what extent these costs shall be paid;

- 4 -

 

	 	(o)	 	we express no opinion as to the enforceability of the provisions of the Credit
Agreement which purport to waive generally all defences which might be available to or
constitute a discharge of the liability of the Borrower;

	 	(p)	 	the Agent on behalf of the Lenders may be required to give the Borrower a
reasonable time to repay following a demand for payment prior to taking any action to
enforce right of repayment or before exercising any of the rights and remedies
expressed to be exercisable by the Agent and/or the Lenders in the Credit Agreement;

	 	(q)	 	the provisions for the payment of interest in the Credit Agreement may not be
enforceable if those provisions provide for the receipt of interest by the Agent and/or
the Lenders at a “criminal rate” within the meaning of section 347 of the Criminal Code
(Canada); and

	 	(r)	 	we express no opinion as to compliance with the Personal Information Protection
and Electronic Documents Act or any other privacy laws with respect to any provision in
the Credit Agreement which purport to grant to the Agent, the Lenders or any other
person, access to books, correspondence, records or other information of the Borrower.

          This opinion is solely for the benefit of the addressees and not for the benefit of any other
person except that it may be relied on by a person who becomes a Lender from time to time under the
Credit Agreement. It is rendered solely in connection with the transaction to which it relates.
It may not be quoted, in whole or in part or otherwise referred to or used for any purpose without
our prior written consent.

Yours truly,

    Right settled in Shares, the gross number of Shares covered by
    the portion of the Award so exercised will cease to be available
    under the Plan. If the exercise price of an Option is paid by
    tender to the Company, or attestation to the ownership, of
    Shares owned by the Participant, the number of Shares available
    for issuance under the Plan will be reduced by the gross number
    of Shares for which the Option is exercised. Shares that have
    actually been issued under the Plan under any Award will not be
    returned to the Plan and will not become available for future
    distribution under the Plan; provided, however, that if unvested
    Shares of Restricted Stock, Performance Shares or Performance
    Units are repurchased by the Company or are forfeited to the
    Company, such Shares will become available for future grant
    under the Plan. Shares used to pay the tax and exercise price of
    an Award will not become available for future grant or sale
    under the Plan. To the extent an Award under the Plan is paid
    out in cash rather than Shares, such cash payment will not
    result in reducing the number of Shares available for issuance
    under the Plan. Notwithstanding the foregoing provisions of this
    Section 3(c), subject to adjustment provided in
    Section 13, the maximum number of Shares that may be issued
    upon the exercise of Incentive Stock Options will equal the
    aggregate Share number stated in Section 3(a), plus, to the
    extent allowable under Section 422 of the Code, any Shares
    that become available for issuance under the Plan under this
    Section 3(c).

 

    (d) Share Reserve.  The Company,
    during the term of this Plan, will at all times reserve and keep
    available such number of Shares as will be sufficient to satisfy
    the requirements of the Plan.

 

    4. Administration of the Plan.

 

    (a) Procedure.

 

    (i) Multiple Administrative
    Bodies.  Different Committees with respect to
    different groups of Service Providers may administer the Plan.

 

    (ii) Section 162(m).  To the
    extent that the Administrator determines it to be desirable to
    qualify Awards granted hereunder as “performance-based
    compensation” within the meaning of Section 162(m) of
    the Code, the Plan will be administered by a Committee of two or
    more “outside directors” within the meaning of
    Section 162(m) of the Code.

 

    (iii)
    Rule 16b-3.  To
    the extent desirable to qualify transactions hereunder as exempt
    under
    Rule 16b-3,
    the transactions contemplated hereunder will be structured to
    satisfy the requirements for exemption under
    Rule 16b-3.

    

    5

 

    (iv) Other Administration.  Other
    than as provided above, the Plan will be administered by
    (A) the Board or (B) a Committee, which committee will
    be constituted to satisfy Applicable Laws.

 

    (b) Powers of the
    Administrator.  Subject to the provisions of
    the Plan, and in the case of a Committee, subject to the
    specific duties delegated by the Board to such Committee, the
    Administrator will have the authority, in its discretion:

 

    (i) to determine the Fair Market Value;

 

    (ii) to select the Service Providers to whom Awards may be
    granted hereunder;

 

    (iii) to determine the number of Shares to be covered by
    each Award granted hereunder;

 

    (iv) to approve forms of agreement for use under the Plan;

 

    (v) to determine the terms and conditions of any, and with
    the approval of the Company’s stockholders, to institute an
    Exchange Program;

 

    (vi) to determine the terms and conditions, not
    inconsistent with the terms of the Plan, of any Award granted
    hereunder. Such terms and conditions include, but are not
    limited to, the exercise price, the time or times when Awards
    may be exercised (which may be based on performance criteria),
    any vesting acceleration or waiver of forfeiture restrictions,
    and any restriction or limitation regarding any Award or the
    Shares relating thereto, based in each case on such factors as
    the Administrator will determine;

 

    (vii) to construe and interpret the terms of the Plan and
    Awards granted pursuant to the Plan;

 

    (viii) to prescribe, amend and rescind rules and
    regulations relating to the Plan, including rules and
    regulations relating to sub-plans established for the purpose of
    satisfying applicable foreign laws;

 

    (ix) to modify or amend each Award (subject to
    Section 18(c) of the Plan), including the discretionary
    authority to extend the post-termination exercisability period
    of Awards longer than is otherwise provided for in the Plan;

 

    (x) to allow Participants to satisfy withholding tax
    obligations by electing to have the Company withhold from the
    Shares to be issued upon exercise of an Award that number of
    Shares having a Fair Market Value equal to the minimum amount
    required to be withheld (the Fair Market Value of the Shares to
    be withheld will be determined on the date that the amount of
    tax to be withheld is to be determined and all elections by a
    Participant to have Shares withheld for this purpose will be
    made in such form and under such conditions as the Administrator
    may deem necessary or advisable);

 

    (xi) to authorize any person to execute on behalf of the
    Company any instrument required to effect the grant of an Award
    previously granted by the Administrator;

 

    (xii) to allow a Participant to defer the receipt of the
    payment of cash or the delivery of Shares that would otherwise
    be due to such Participant under an Award

 

    (xiii) to make all other determinations deemed necessary or
    advisable for administering the Plan.

 

    (c) Prohibition Against
    Repricing.  Subject to adjustments made
    pursuant to Section 13, in no event shall the Administrator
    have the right to amend the terms of any Award to reduce the
    exercise price of such outstanding Award or cancel an
    outstanding Award in exchange for cash or other Awards with an
    exercise price that is less than the exercise price of the
    original Award without stockholder approval.

 

    (d) Effect of Administrator’s
    Decision.  The Administrator’s decisions,
    determinations and interpretations will be final and binding on
    all Participants and any other holders of Awards.

 

    5. Eligibility.  Nonstatutory Stock
    Options, Restricted Stock, Stock Appreciation Rights,
    Performance Units and Performance Shares may be granted to
    Service Providers. Incentive Stock Options may be granted only
    to Employees.

    

    6

 

    6. Stock Options.

 

    (a) Limitations.

 

    (i) Each Option will be designated in the Award Agreement
    as either an Incentive Stock Option or a Nonstatutory Stock
    Option. However, notwithstanding such designation, to the extent
    that the aggregate Fair Market Value of the Shares with respect
    to which Incentive Stock Options are exercisable for the first
    time by the Participant during any calendar year (under all
    plans of the Company and any Parent or Subsidiary) exceeds
    $100,000, such Options will be treated as Nonstatutory Stock
    Options. For purposes of this Section 6(a), Incentive Stock
    Options will be taken into account in the order in which they
    were granted. The Fair Market Value of the Shares will be
    determined as of the time the Option with respect to such Shares
    is granted.

 

    (ii) The following limitations will apply to grants of
    Options:

 

    (1) No Service Provider will be granted, in any Fiscal
    Year, Options to purchase more than 1,500,000 Shares.

 

    (2) In connection with his or her initial service, a
    Service Provider may be granted Options to purchase up to an
    additional 1,500,000 Shares, which will not count against
    the limit set forth in Section 6(a)(ii)(1) above.

 

    (3) The foregoing limitations will be adjusted
    proportionately in connection with any change in the
    Company’s capitalization as described in Section 13.

 

    (4) If an Option is cancelled in the same Fiscal Year in
    which it was granted (other than in connection with a
    transaction described in Section 13), the cancelled Option will
    be counted against the limits set forth in subsections (1)
    and (2) above.

 

    (b) Term of Option.  The term of
    each Option will be stated in the Award Agreement. In the case
    of an Incentive Stock Option, the term will be ten
    (10) years from the date of grant or such shorter term as
    may be provided in the Award Agreement. Moreover, in the case of
    an Incentive Stock Option granted to a Participant who, at the
    time the Incentive Stock Option is granted, owns stock
    representing more than ten percent (10%) of the total combined
    voting power of all classes of stock of the Company or any
    Parent or Subsidiary, the term of the Incentive Stock Option
    will be five (5) years from the date of grant or such
    shorter term as may be provided in the Award Agreement.

 

    (c) Option Exercise Price and Consideration.

 

    (i) Exercise Price.  The per share
    exercise price for the Shares to be issued pursuant to exercise
    of an Option will be determined by the Administrator, subject to
    the following:

 

    (1) In the case of an Incentive Stock Option

 

    a) granted to an Employee who, at the time the Incentive
    Stock Option is granted, owns stock representing more than ten
    percent (10%) of the voting power of all classes of stock of the
    Company or any Parent or Subsidiary, the per Share exercise
    price will be no less than 110% of the Fair Market Value per
    Share on the date of grant.

 

    b) granted to any Employee other than an Employee described
    in paragraph (A) immediately above, the per Share exercise
    price will be no less than 100% of the Fair Market Value per
    Share on the date of grant.

 

    c) Notwithstanding the foregoing, Incentive Stock Options
    may be granted with a per Share exercise price of less than 100%
    of the Fair Market Value per Share on the date of grant pursuant
    to a transaction described in, and in a manner consistent with,
    Section 424(a) of the Code.

 

    (2) In the case of a Nonstatutory Stock Option, the per
    Share exercise price will be determined by the Administrator. In
    the case of a Nonstatutory Stock Option intended to qualify as
    “performance-based compensation” within the meaning of
    Section 162(m) of the Code, the per Share exercise price
    will be no less than 100% of the Fair Market Value per Share on
    the date of grant.

    

    7

 

    (ii) Waiting Period and Exercise
    Dates.  At the time an Option is granted, the
    Administrator will fix the period within which the Option may be
    exercised and will determine any conditions that must be
    satisfied before the Option may be exercised.

 

    (iii) Form of Consideration.  The
    Administrator will determine the acceptable form of
    consideration for exercising an Option, including the method of
    payment. In the case of an Incentive Stock Option, the
    Administrator will determine the acceptable form of
    consideration at the time of grant. Such consideration may
    consist entirely of: (1) cash; (2) check;
    (3) promissory note; (4) other Shares, provided that
    such Shares have a Fair Market Value on the date of surrender
    equal to the aggregate exercise price of the Shares as to which
    said Option will be exercised and provided that accepting such
    Shares, in the sole discretion of the Administrator, shall not
    result in any adverse accounting consequences to the Company;
    (5) consideration received by the Company under a cashless
    exercise program implemented by the Company in connection with
    the Plan; (6) a reduction in the amount of any Company
    liability to the Participant, including any liability
    attributable to the Participant’s participation in any
    Company-sponsored deferred compensation program or arrangement;
    (7) such other consideration and method of payment for the
    issuance of Shares to the extent permitted by Applicable Laws;
    or (8) any combination of the foregoing methods of payment.

 

    (d) Exercise of Option.

 

    (i) Procedure for Exercise; Rights as a
    Stockholder.  Any Option granted hereunder
    will be exercisable according to the terms of the Plan and at
    such times and under such conditions as determined by the
    Administrator and set forth in the Award Agreement. An Option
    may not be exercised for a fraction of a Share.

 

    An Option will be deemed exercised when the Company receives:
    (i) written or electronic notice of exercise (in accordance
    with the Award Agreement) from the person entitled to exercise
    the Option, and (ii) full payment for the Shares with
    respect to which the Option is exercised. Full payment may
    consist of any consideration and method of payment authorized by
    the Administrator and permitted by the Award Agreement and the
    Plan. Shares issued upon exercise of an Option will be issued in
    the name of the Participant or, if requested by the Participant,
    in the name of the Participant and his or her spouse. Until the
    Shares are issued (as evidenced by the appropriate entry on the
    books of the Company or of a duly authorized transfer agent of
    the Company), no right to vote or receive dividends or any other
    rights as a stockholder will exist with respect to the Shares,
    notwithstanding the exercise of the Option. The Company will
    issue (or cause to be issued) such Shares promptly after the
    Option is exercised. No adjustment will be made for a dividend
    or other right for which the record date is prior to the date
    the Shares are issued, except as provided in Section 13 of
    the Plan.

 

    Exercising an Option in any manner will decrease the number of
    Shares thereafter available, both for purposes of the Plan and
    for sale under the Option, by the number of Shares as to which
    the Option is exercised.

 

    (ii) Termination of Relationship as a Service
    Provider.  If a Participant ceases to be a
    Service Provider, other than upon the Participant’s death
    or Disability, the Participant may exercise his or her Option
    within such period of time as is specified in the Award
    Agreement to the extent that the Option is vested on the date of
    termination (but in no event later than the expiration of the
    term of such Option as set forth in the Award Agreement). In the
    absence of a specified time in the Award Agreement, the Option
    will remain exercisable for three (3) months following the
    Participant’s termination. Unless otherwise provided by the
    Administrator, if on the date of termination the Participant is
    not vested as to his or her entire Option, the Shares covered by
    the unvested portion of the Option will revert to the Plan. If
    after termination the Participant does not exercise his or her
    Option within the time specified by the Administrator, the
    Option will terminate, and the Shares covered by such Option
    will revert to the Plan.

 

    (iii) Disability of
    Participant.  If a Participant ceases to be a
    Service Provider as a result of the Participant’s
    Disability, the Participant may exercise his or her Option
    within such period of time as is specified in the Award
    Agreement to the extent the Option is vested on the date of
    termination (but in no event later than the expiration of the
    term of such Option as set forth in the Award Agreement). In the
    absence of a specified time in the Award Agreement, the Option
    will remain exercisable for twelve (12) months following
    the Participant’s termination. Unless otherwise provided by
    the Administrator, if on the date of termination the Participant
    is not vested as to his or her entire Option, the Shares covered
    by the unvested portion of the Option will revert to the Plan.
    If after

    

    8

 

    termination the Participant does not exercise his or her Option
    within the time specified herein, the Option will terminate, and
    the Shares covered by such Option will revert to the Plan.

 

    (iv) Death of Participant.  If a
    Participant dies while a Service Provider, the Option may be
    exercised following the Participant’s death within such
    period of time as is specified in the Award Agreement to the
    extent that the Option is vested on the date of death (but in no
    event may the option be exercised later than the expiration of
    the term of such Option as set forth in the Award Agreement), by
    the Participant’s designated beneficiary, provided such
    beneficiary has been designated prior to Participant’s
    death in a form acceptable to the Administrator. If no such
    beneficiary has been designated by the Participant, then such
    Option may be exercised by the personal representative of the
    Participant’s estate or by the person(s) to whom the Option
    is transferred pursuant to the Participant’s will or in
    accordance with the laws of descent and distribution. In the
    absence of a specified time in the Award Agreement, the Option
    will remain exercisable for twelve (12) months following
    Participant’s death. Unless otherwise provided by the
    Administrator, if at the time of death Participant is not vested
    as to his or her entire Option, the Shares covered by the
    unvested portion of the Option will immediately revert to the
    Plan. If the Option is not so exercised within the time
    specified herein, the Option will terminate, and the Shares
    covered by such Option will revert to the Plan.

 

    7. Restricted Stock.

 

    (a) Grant of Restricted
    Stock.  Subject to the terms and provisions of
    the Plan, the Administrator, at any time and from time to time,
    may grant Shares of Restricted Stock to Service Providers in
    such amounts as the Administrator, in its sole discretion, will
    determine.

 

    (b) Restricted Stock
    Agreement.  Each Award of Restricted Stock
    will be evidenced by an Award Agreement that will specify the
    Period of Restriction, the number of Shares granted, and such
    other terms and conditions as the Administrator, in its sole
    discretion, will determine. Notwithstanding the foregoing
    sentence, for Restricted Stock intended to qualify as
    “performance-based compensation” within the meaning of
    Section 162(m) of the Code, during any Fiscal Year no
    Participant will receive more than an aggregate of
    1,000,000 Shares of Restricted Stock. Notwithstanding the
    foregoing limitation, in connection with his or her initial
    service as an Employee, for Restricted Stock intended to qualify
    as “performance-based compensation” within the meaning
    of Section 162(m) of the Code, an Employee may be granted
    an aggregate of up to an additional 1,000,000 Shares of
    Restricted Stock. Unless the Administrator determines otherwise,
    Shares of Restricted Stock will be held by the Company as escrow
    agent until the restrictions on such Shares have lapsed.

 

    (c) Transferability.  Except as
    provided in this Section 7, Shares of Restricted Stock may
    not be sold, transferred, pledged, assigned, or otherwise
    alienated or hypothecated until the end of the applicable Period
    of Restriction.

 

    (d) Other Restrictions.  The
    Administrator, in its sole discretion, may impose such other
    restrictions on Shares of Restricted Stock as it may deem
    advisable or appropriate.

 

    (e) Removal of
    Restrictions.  Except as otherwise provided in
    this Section 7, Shares of Restricted Stock covered by each
    Restricted Stock grant made under the Plan will be released from
    escrow as soon as practicable after the last day of the Period
    of Restriction. The Administrator, in its discretion, may
    accelerate the time at which any restrictions will lapse or be
    removed.

 

    (f) Voting Rights.  During the
    Period of Restriction, Service Providers holding Shares of
    Restricted Stock granted hereunder may exercise full voting
    rights with respect to those Shares, unless the Administrator
    determines otherwise.

 

    (g) Dividends and Other
    Distributions.  During the Period of
    Restriction, Service Providers holding Shares of Restricted
    Stock will be entitled to receive all dividends and other
    distributions paid with respect to such Shares unless otherwise
    provided in the Award Agreement. If any such dividends or
    distributions are paid in Shares, the Shares will be subject to
    the same restrictions on transferability and forfeitability as
    the Shares of Restricted Stock with respect to which they were
    paid.

    

    9

 

    (h) Return of Restricted Stock to
    Company.  On the date set forth in the Award
    Agreement, the Restricted Stock for which restrictions have not
    lapsed will revert to the Company and again will become
    available for grant under the Plan.

 

    (i) Section 162(m) Performance
    Restrictions.  For purposes of qualifying
    grants of Restricted Stock as “performance-based
    compensation” under Section 162(m) of the Code, the
    Administrator, in its discretion, may set restrictions based
    upon the achievement of Performance Goals. The Performance Goals
    will be set by the Administrator on or before the Determination
    Date. In granting Restricted Stock which is intended to qualify
    under Section 162(m) of the Code, the Administrator will
    follow any procedures determined by it from time to time to be
    necessary or appropriate to ensure qualification of the Award
    under Section 162(m) of the Code (e.g., in determining the
    Performance Goals).

 

    8. Stock Appreciation Rights.

 

    (a) Grant of SARs.  Subject to the
    terms and conditions of the Plan, a SAR may be granted to
    Service Providers at any time and from time to time as will be
    determined by the Administrator, in its sole discretion. The
    Administrator may grant Affiliated SARs, Freestanding SARs,
    Tandem SARs, or any combination thereof.

 

    (b) Number of Shares.  The Administrator
    will have complete discretion to determine the number of SARs
    granted to any Service Provider; provided, however, no Service
    Provider will be granted, in any Fiscal Year, SARs covering more
    than 1,500,000 Shares. Notwithstanding the limitation in
    the previous sentence, in connection with his or her initial
    service a Service Provider may be granted SARs covering up to an
    additional 1,500,000 Shares. The foregoing limitations will
    be adjusted proportionately in connection with any change in the
    Company’s capitalization as described in Section 13.
    In addition, if a SAR is cancelled in the same Fiscal Year in
    which it was granted (other than in connection with a
    transaction described in Section 13), the cancelled SAR
    will be counted against the numerical share limits set forth
    above.

 

    (c) Exercise Price and Other
    Terms.  The Administrator, subject to the
    provisions of the Plan, will have complete discretion to
    determine the terms and conditions of SARs granted under the
    Plan; provided, however, that the per Share exercise price of a
    SAR will be no less than 100% of the Fair Market Value per Share
    on the date of grant. However, the exercise price of Tandem or
    Affiliated SARs will equal the exercise price of the related
    Option.

 

    (d) Exercise of Tandem
    SARs.  Tandem SARs may be exercised for all or
    part of the Shares subject to the related Option upon the
    surrender of the right to exercise the equivalent portion of the
    related Option. A Tandem SAR may be exercised only with respect
    to the Shares for which its related Option is then exercisable.
    With respect to a Tandem SAR granted in connection with an
    Incentive Stock Option: (a) the Tandem SAR will expire no
    later than the expiration of the underlying Incentive Stock
    Option; (b) the value of the payout with respect to the
    Tandem SAR will be for no more than one hundred percent (100%)
    of the difference between the exercise price of the underlying
    Incentive Stock Option and the Fair Market Value of the Shares
    subject to the underlying Incentive Stock Option at the time the
    Tandem SAR is exercised; and (c) the Tandem SAR will be
    exercisable only when the Fair Market Value of the Shares
    subject to the Incentive Stock Option exceeds the Exercise Price
    of the Incentive Stock Option.

 

    (e) Exercise of Affiliated
    SARs.  An Affiliated SAR will be deemed to be
    exercised upon the exercise of the related Option. The deemed
    exercise of an Affiliated SAR will not necessitate a reduction
    in the number of Shares subject to the related Option.

 

    (f) Exercise of Freestanding
    SARs.  Freestanding SARs will be exercisable
    on such terms and conditions as the Administrator, in its sole
    discretion, will determine.

 

    (g) SAR Agreement.  Each SAR grant
    will be evidenced by an Award Agreement that will specify the
    exercise price, the term of the SAR, the conditions of exercise,
    and such other terms and conditions as the Administrator, in its
    sole discretion, will determine.

 

    (h) Maximum Term/Expiration of
    SARs.  An SAR granted under the Plan will
    expire upon the date determined by the Administrator, in its
    sole discretion, and set forth in the Award Agreement.
    Notwithstanding

    

    10

 

    the foregoing, the rules of Section 6(b) relating to the
    maximum term and Section 6(d) relating to exercise also
    will apply to SARs.

 

    (i) Payment of SAR Amount.  Upon
    exercise of an SAR, a Participant will be entitled to receive
    payment from the Company in an amount determined by multiplying:

 

    (i) The difference between the Fair Market Value of a Share
    on the date of exercise over the exercise price; times

 

    (ii) The number of Shares with respect to which the SAR is
    exercised.

 

    At the discretion of the Administrator, the payment upon SAR
    exercise may be in cash, in Shares of equivalent value, or in
    some combination thereof.

 

    9. Performance Units and Performance Shares.

 

    (a) Grant of Performance
    Units/Shares.  Performance Units and
    Performance Shares may be granted to Service Providers at any
    time and from time to time, as will be determined by the
    Administrator, in its sole discretion. The Administrator will
    have complete discretion in determining the number of
    Performance Units and Performance Shares granted to each
    Participant provided that during any Fiscal Year, for
    Performance Units or Performance Shares intended to qualify as
    “performance-based compensation” within the meaning of
    Section 162(m) of the Code, (i) no Participant will
    receive Performance Units having an initial value greater than
    $4,000,000, and (ii) no Participant will receive more than
    1,000,000 Performance Shares. Notwithstanding the foregoing
    limitation, for Performance Shares intended to qualify as
    “performance-based compensation” within the meaning of
    Section 162(m) of the Code, in connection with his or her
    initial service, a Service Provider may be granted up to an
    additional 1,000,000 Performance Shares.

 

    (b) Value of Performance
    Units/Shares.  Each Performance Unit will have
    an initial value that is established by the Administrator on or
    before the date of grant. Each Performance Share will have an
    initial value equal to the Fair Market Value of a Share on the
    date of grant.

 

    (c) Performance Objectives and Other
    Terms.  The Administrator will set performance
    objectives or other vesting provisions in its discretion which,
    depending on the extent to which they are met, will determine
    the number or value of Performance Units/Shares that will be
    paid out to the Service Providers. Each Award of Performance
    Units/Shares will be evidenced by an Award Agreement that will
    specify the Performance Period, and such other terms and
    conditions as the Administrator, in its sole discretion, will
    determine. The Administrator may set performance objectives
    based upon the achievement of Company-wide, divisional, or
    individual goals, applicable federal or state securities laws,
    or any other basis determined by the Administrator in its
    discretion.

 

    (d) Earning of Performance
    Units/Shares.  After the applicable
    Performance Period has ended, the holder of Performance
    Units/Shares will be entitled to receive a payout of the number
    of Performance Units/Shares earned by the Participant over the
    Performance Period, to be determined as a function of the extent
    to which the corresponding performance objectives or other
    vesting provisions have been achieved. After the grant of a
    Performance Unit/Share, the Administrator, in its sole
    discretion, may reduce or waive any performance objectives or
    other vesting provisions for such Performance Unit/Share.

 

    (e) Form and Timing of Payment of Performance
    Units/Shares.  Payment of earned Performance
    Units/Shares
    will be made as soon as practicable after the expiration of the
    applicable Performance Period. The Administrator, in its sole
    discretion, may pay earned Performance Units/Shares in the form
    of cash, in Shares (which have an aggregate Fair Market Value
    equal to the value of the earned Performance Units/Shares at the
    close of the applicable Performance Period) or in a combination
    thereof.

 

    (f) Cancellation of Performance
    Units/Shares.  On the date set forth in the
    Award Agreement, all unearned or unvested Performance
    Units/Shares will be forfeited to the Company, and again will be
    available for grant under the Plan.

 

    (g) Section 162(m) Performance
    Restrictions.  For purposes of qualifying
    grants of Performance Units/Shares as “performance-based
    compensation” under Section 162(m) of the Code, the
    Administrator, in its discretion, may set restrictions based
    upon the achievement of Performance Goals. The Performance Goals
    will

    

    11

 

    be set by the Administrator on or before the Determination Date.
    In granting Performance Units/Shares which are intended to
    qualify under Section 162(m) of the Code, the Administrator
    will follow any procedures determined by it from time to time to
    be necessary or appropriate to ensure qualification of the Award
    under Section 162(m) of the Code (e.g., in determining the
    Performance Goals).

 

    10. Performance Goals.  The
    granting
    and/or
    vesting of Awards of Restricted Stock, Performance Shares and
    Performance Units and other incentives under the Plan may be
    made subject to the attainment of performance goals relating to
    one or more business criteria within the meaning of
    Section 162(m) of the Code and may provide for a targeted
    level or levels of achievement (“Performance Goals” )
    including: (i) Cash Position, (ii) Clinical
    Progression, (iii) Collaboration Arrangement,
    (iv) Collaboration Progression, (v) Earnings Per
    Share, (vi) Financing Event, (vii) Net Income,
    (viii) Operating Cash Flow, (ix) Operating Expenses,
    (x) Operating Income, (xi) Product Approval,
    (xii) Product Revenues, (xiii) Profit After Tax,
    (xiv) Projects in Development, (xv) Regulatory
    Filings, (xvi) Return on Assets, (xvii) Return on
    Equity, (xviii) Revenue Growth, and (xix) Total
    Stockholder Return. Prior to the Determination Date, the
    Administrator will determine whether any significant element(s)
    will be included in or excluded from the calculation of any
    Performance Goal with respect to any Participant. Any
    Performance Goals may be used to measure the performance of the
    Company as a whole or a business unit of the Company and may be
    measured relative to a peer group or index. With respect to any
    Award, Performance Goals may be used alone or in combination.
    The Performance Goals may differ from Participant to Participant
    and from Award to Award. Prior to the Determination Date, the
    Administrator will determine whether any significant element(s)
    will be included in or excluded from the calculation of any
    Performance Goal with respect to any Participant. In all other
    respects, Performance Goals will be calculated in accordance
    with the Company’s financial statements, generally accepted
    accounting principles, or under a methodology established by the
    Administrator prior to the issuance of an Award, which is
    consistently applied and identified in the financial statements,
    including footnotes, or the management discussion and analysis
    section of the Company’s annual report. In determining the
    amounts earned by a Participant pursuant to an Award intended to
    qualified as “performance-based compensation” under
    Section 162(m) of the Code, the Administrator will have the
    right to reduce or eliminate (but not to increase) the amount
    payable at a given level of performance to take into account
    additional factors that the Administrator may deem relevant to
    the assessment of individual or corporate performance for the
    Performance Period. A Participant will be eligible to receive
    payment pursuant to an Award intended to qualify as
    “performance-based compensation” under
    Section 162(m) of the Code for a Performance Period only if
    the Performance Goals for such period are achieved.

 

    11. Leaves of Absence.  Unless the
    Administrator provides otherwise, vesting of Awards granted
    hereunder will be suspended during any unpaid leave of absence.
    A Service Provider will not cease to be an Employee in the case
    of (i) any leave of absence approved by the Company or
    (ii) transfers between locations of the Company or between
    the Company, its Parent, or any Subsidiary. For purposes of
    Incentive Stock Options, no such leave may exceed ninety
    (90) days, unless reemployment upon expiration of such
    leave is guaranteed by statute or contract. If reemployment upon
    expiration of a leave of absence approved by the Company is not
    so guaranteed, then six months and a day following the
    1st day of such leave any Incentive Stock Option held by
    the Participant will cease to be treated as an Incentive Stock
    Option and will be treated for tax purposes as a Nonstatutory
    Stock Option.

 

    12. Transferability of
    Awards.  Unless determined otherwise by the
    Administrator, an Award may not be sold, pledged, assigned,
    hypothecated, transferred, or disposed of in any manner other
    than by will or by the laws of descent or distribution and may
    be exercised, during the lifetime of the Participant, only by
    the Participant. If the Administrator makes an Award
    transferable, such Award will contain such additional terms and
    conditions as the Administrator deems appropriate; provided,
    however, that the Administrator may only make an Award
    transferable to one or more of the following: (i) the
    Participant’s spouse, children or grandchildren (including
    any adopted and step children or grandchildren), parents,
    grandparents, siblings or any “Family Member” (as
    defined pursuant to Rule 701 of the Securities Act of 1933,
    as amended) of the Participant; (ii) a trust for the
    benefit of one or more of the Participant or the persons
    referred to in clause (i); (iii) a partnership, limited
    liability company or corporation in which the Participant or the
    persons referred to in clause (i) are the only partners,
    members or stockholders; or (iv) charitable donations.

    

    12

 

    13. Adjustments; Dissolution or Liquidation; Merger
    or Change in Control.

 

    (a) Adjustments.  In the event that
    any dividend or other distribution (whether in the form of cash,
    Shares, other securities, or other property), recapitalization,
    stock split, reverse stock split, reorganization, merger,
    consolidation,
    split-up,
    spin-off, combination, repurchase, or exchange of Shares or
    other securities of the Company, or other change in the
    corporate structure of the Company affecting the Shares occurs,
    the Administrator, in order to prevent diminution or enlargement
    of the benefits or potential benefits intended to be made
    available under the Plan, shall appropriately adjust the number
    and class of Shares that may be delivered under the Plan
    and/or the
    number, class, and price of Shares covered by each outstanding
    Award, the numerical Share limits in Sections 3, 6, 7, 8,
    and 9 of the Plan.

 

    (b) Dissolution or Liquidation.  In
    the event of the proposed dissolution or liquidation of the
    Company, the Administrator will notify each Participant as soon
    as practicable prior to the effective date of such proposed
    transaction. To the extent it has not been previously exercised,
    an Award will terminate immediately prior to the consummation of
    such proposed action.

 

    (c) Change in Control.  In the
    event of a Change in Control, each outstanding Award will be
    assumed or an equivalent option or right substituted by the
    successor corporation or a Parent or Subsidiary of the successor
    corporation. In the event that the successor corporation refuses
    to assume or substitute for the Award, the Participant will
    fully vest in and have the right to exercise all of his or her
    outstanding Options and Stock Appreciation Rights, including
    Shares as to which such Awards would not otherwise be vested or
    exercisable, all restrictions on Restricted Stock shall lapse,
    and, with respect to Performance Shares and Performance Units,
    all performance goals or other vesting criteria will be deemed
    achieved at target levels and all other terms and conditions
    met. In addition, if an Option or Stock Appreciation Right is
    not assumed or substituted for in the event of a Change in
    Control, the Administrator will notify the Participant in
    writing or electronically that the Option or Stock Appreciation
    Right will be fully vested and exercisable for a period of time
    determined by the Administrator in its sole discretion, and the
    Option or Stock Appreciation Right will terminate upon the
    expiration of such period.

 

    With respect to Awards granted to an Outside Director that are
    assumed or substituted for, if on the date of or following such
    assumption or substitution the Participant’s status as a
    Director or a director of the successor corporation, as
    applicable, is terminated other than upon a voluntary
    resignation by the Participant not at the request of the
    successor, then the Participant will fully vest in and have the
    right to exercise Options
    and/or Stock
    Appreciation Rights as to all of the Shares subject to the
    Award, including Shares as to which such Awards would not
    otherwise be vested or exercisable, all restrictions on
    Restricted Stock shall lapse, and, with respect to Performance
    Shares and Performance Units, all performance goals or other
    vesting criteria will be deemed achieved at target levels and
    all other terms and conditions met.

 

    For the purposes of this subsection (c), an Award will be
    considered assumed if, following the Change in Control, the
    Award confers the right to purchase or receive, for each Share
    subject to the Award immediately prior to the Change in Control,
    the consideration (whether stock, cash, or other securities or
    property) or, in the case of a Stock Appreciation Right upon the
    exercise of which the Administrator determines to pay cash or a
    Performance Share or Performance Unit which the Administrator
    can determine to pay in cash, the fair market value of the
    consideration received in the merger or Change in Control by
    holders of Common Stock for each Share held on the effective
    date of the transaction (and if holders were offered a choice of
    consideration, the type of consideration chosen by the holders
    of a majority of the outstanding Shares); provided, however,
    that if such consideration received in the Change in Control is
    not solely common stock of the successor corporation or its
    Parent, the Administrator may, with the consent of the successor
    corporation, provide for the consideration to be received upon
    the exercise of an Option or Stock Appreciation Right or upon
    the payout of a Performance Share or Performance Unit, for each
    Share subject to such Award (or in the case of Performance
    Units, the number of implied shares determined by dividing the
    value of the Performance Units by the per share consideration
    received by holders of Common Stock in the Change in Control),
    to be solely common stock of the successor corporation or its
    Parent equal in fair market value to the per share consideration
    received by holders of Common Stock in the Change in Control.

 

    Notwithstanding anything in this Section 13(c) to the
    contrary, an Award that vests, is earned or paid-out upon the
    satisfaction of one or more performance goals will not be
    considered assumed if the Company or its successor

    

    13

 

    modifies any of such performance goals without the
    Participant’s consent; provided, however, a modification to
    such performance goals only to reflect the successor
    corporation’s post-Change in Control corporate structure
    will not be deemed to invalidate an otherwise valid Award
    assumption.

 

    14. Tax Withholding

 

    (a) Withholding
    Requirements.  Prior to the delivery of any
    Shares or cash pursuant to an Award (or exercise thereof), the
    Company will have the power and the right to deduct or withhold,
    or require a Participant to remit to the Company, an amount
    sufficient to satisfy federal, state, local, foreign or other
    taxes (including the Participant’s FICA obligation)
    required to be withheld with respect to such Award (or exercise
    thereof).

 

    (b) Withholding Arrangements.  The
    Administrator, in its sole discretion and pursuant to such
    procedures as it may specify from time to time, may permit a
    Participant to satisfy such tax withholding obligation, in whole
    or in part by (without limitation) (i) paying cash,
    (ii) electing to have the Company withhold otherwise
    deliverable cash or Shares having a Fair Market Value equal to
    the amount required to be withheld, (iii) delivering to the
    Company already-owned Shares having a Fair Market Value equal to
    the amount required to be withheld, or (iv) selling a
    sufficient number of Shares otherwise deliverable to the
    Participant through such means as the Administrator may
    determine in its sole discretion (whether through a broker or
    otherwise) equal to the amount required to be withheld. The
    amount of the withholding requirement will be deemed to include
    any amount which the Administrator agrees may be withheld at the
    time the election is made, not to exceed the amount determined
    by using the maximum federal, state or local marginal income tax
    rates applicable to the Participant with respect to the Award on
    the date that the amount of tax to be withheld is to be
    determined. The Fair Market Value of the Shares to be withheld
    or delivered will be determined as of the date that the taxes
    are required to be withheld.

 

    15. No Effect on Employment or
    Service.  Neither the Plan nor any Award will
    confer upon a Participant any right with respect to continuing
    the Participant’s relationship as a Service Provider with
    the Company, nor will they interfere in any way with the
    Participant’s right or the Company’s right to
    terminate such relationship at any time, with or without cause,
    to the extent permitted by Applicable Laws.

 

    16. Date of Grant.  The date of
    grant of an Award will be, for all purposes, the date on which
    the Administrator makes the determination granting such Award,
    or such later date as is determined by the Administrator. Notice
    of the determination will be provided to each Participant within
    a reasonable time after the date of such grant.

 

    17. Term of Plan.  Subject to
    Section 21 of the Plan, the Plan will become effective upon
    its adoption by the Board. It will continue in effect for a term
    of ten (10) years unless terminated earlier under
    Section 18 of the Plan.

 

    18. Amendment and Termination of the Plan.

 

    (a) Amendment and Termination.  The
    Administrator may at any time amend, alter, suspend or terminate
    the Plan.

 

    (b) Stockholder Approval.  The
    Company will obtain stockholder approval of any Plan amendment
    to the extent necessary and desirable to comply with Applicable
    Laws.

 

    (c) Effect of Amendment or
    Termination.  No amendment, alteration,
    suspension or termination of the Plan will impair the rights of
    any Participant, unless mutually agreed otherwise between the
    Participant and the Administrator, which agreement must be in
    writing and signed by the Participant and the Company.
    Termination of the Plan will not affect the Administrator’s
    ability to exercise the powers granted to it hereunder with
    respect to Awards granted under the Plan prior to the date of
    such termination.

 

    19. Conditions Upon Issuance of Shares.

 

    (a) Legal Compliance.  Shares will
    not be issued pursuant to the exercise of an Award unless the
    exercise of such Award and the issuance and delivery of such
    Shares will comply with Applicable Laws and will be further
    subject to the approval of counsel for the Company with respect
    to such compliance.

 

    (b) Investment Representations.  As
    a condition to the exercise of an Award, the Company may require
    the person exercising such Award to represent and warrant at the
    time of any such exercise that the Shares are being

    

    14

 

    purchased only for investment and without any present intention
    to sell or distribute such Shares if, in the opinion of counsel
    for the Company, such a representation is required.

 

    20. Inability to Obtain
    Authority.  The inability of the Company to
    obtain authority from any regulatory body having jurisdiction,
    which authority is deemed by the Company’s counsel to be
    necessary to the lawful issuance and sale of any Shares
    hereunder, will relieve the Company of any liability in respect
    of the failure to issue or sell such Shares as to which such
    requisite authority will not have been obtained.

 

    21. Stockholder Approval.  The Plan
    will be subject to approval by the stockholders of the Company
    within twelve (12) months after the date the Plan is
    adopted. Such stockholder approval will be obtained in the
    manner and to the degree required under Applicable Laws.
