AMOUNTS AND TERMS OF THE ADVANCES

     SECTION 2.01. Existing Advances. (a) The Existing Lenders have made the Existing Term Advances to the Borrower pursuant to the
Existing Credit Agreement. For the avoidance of doubt, notwithstanding the amendment and
restatement of the Existing Credit Agreement contained herein, the Existing Term Advances shall for
all purposes constitute Advances hereunder and provisions relating to the Notice of Borrowing
contained in Section 2.02 shall have no effect on the Existing Term Advances. Amounts borrowed
under this Section 2.01(a) and repaid or prepaid may not be reborrowed.

Second Lien Credit Agreement

 

32

          (b) Term Advances. Each Term Lender severally agrees, on the terms and conditions
hereinafter set forth, to make a single advance (a “Term Advance”) to the Borrower on the
Effective Date in an amount not to exceed such Term Lender’s Term Commitment at such time. The
Borrowing shall consist of Term Advances made simultaneously by the Term Lenders according to their
Term Commitments. Amounts borrowed under this Section 2.01(b) and repaid or prepaid may not be
reborrowed. Each of the parties hereto agrees that the Administrative Agent may, in consultation
with the Borrower, take any and all action as may be reasonably necessary to ensure that on the
Effective Date, the aggregate principal amount of the Term Advances shall be added to (and form
part of) the existing Borrowing under the Existing Credit Agreement, so that each Lender will
participate proportionately in the existing Borrowing under the Existing Credit Agreement and so
that the Existing Lenders continue to have the same participation (by amount) in the Borrowing as
they had before the making of the Term Advances. In connection therewith, the Borrower agrees to
compensate the Lenders, pursuant to Section 10.04(c), on such basis as may be agreed between the
Borrower and the Administrative Agent.

     SECTION 2.02. Making the Advances. (a) Each Borrowing shall be made on notice, given not
later than 9:00 A.M. (New York City time) on the Effective Date by the Borrower to the
Administrative Agent, which shall give to each Lender prompt notice thereof by telex or telecopier.
Such notice of Borrowing (the “Notice of Borrowing”) shall be by telephone, confirmed immediately
in writing, or telex or telecopier, in substantially the form of Exhibit B hereto, specifying
therein the requested (i) date of the Borrowing, (ii) Type of Advances comprising the Borrowing,
(iii) aggregate amount of the Borrowing and (iv) if the Borrowing consists of Eurodollar Rate
Advances, initial Interest Period for each such Advance. Each Lender shall, before 11:00 A.M. (New
York City time) on the Effective Date, make available for the account of its Applicable Lending
Office to the Administrative Agent at the Administrative Agent’s Account, in same day funds, such
Lender’s ratable portion of the Borrowing in accordance with the respective Commitment of such
Lender and the other Lenders. After the Administrative Agent’s receipt of such funds and upon
fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will
make such funds available to the Borrower by crediting the Borrower’s Account before noon (New York
City time).

          (b) Each Notice of Borrowing shall be irrevocable and binding on the Borrower. If any Notice
of Borrowing specifies that the Borrowing is to be comprised of Eurodollar Rate Advances, the
Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a
result of any failure to fulfill on or before the date specified in such Notice of Borrowing the
applicable conditions set forth in Article III, including, without limitation, any loss (including
loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment
of deposits or other funds acquired by such Lender to fund the Advance to be made by such Lender as
part of such Borrowing when such Advance, as a result of such failure, is not made on such date.

          (c) Unless the Administrative Agent shall have received notice from a Lender prior to the
Effective Date that such Lender will not make available to the Administrative Agent such Lender’s
ratable portion of such Borrowing, the Administrative Agent may assume that such Lender has made
such portion available to the Administrative Agent on the Effective Date in accordance with
subsection (a) of this Section 2.02 and the Administrative Agent may, in reliance upon such
assumption, make available to
the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not
have so made such ratable portion available to the Administrative Agent and the Borrower has been
advanced such corresponding amount, such Lender and the Borrower severally agree to repay or pay to
the Administrative Agent forthwith on demand such corresponding amount and to pay interest thereon,
for each day from the date such amount is made available to the Borrower until the date such amount
is repaid or paid to the Administrative Agent, at (i) in the case of the Borrower, the interest
rate applicable at such time under Section 2.05 to Advances comprising such Borrowing and (ii) in
the case of such Lender, the Federal Funds Rate. If such Lender shall pay to the Administrative
Agent such corresponding

Second Lien Credit Agreement

 

33

amount, such amount so paid shall constitute such Lender’s Advance as part
of such Borrowing for all purposes.

          (d) The failure of any Lender to make any Advance to be made by it as part of any Borrowing
shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the
Effective Date, but no Lender shall be responsible for the failure of any other Lender to make the
Advance to be made by such other Lender on the Effective Date.

     SECTION 2.03. Repayment of Advances. On the Maturity Date, the Borrower shall repay to the
Administrative Agent for the ratable account of the Lenders the aggregate principal amount of the
Advances outstanding on such date.

     SECTION 2.04. Prepayments and Reductions. The Borrower may, upon at least five Business
Days’ notice to the Administrative Agent stating the proposed date and aggregate principal amount
of the prepayment, and if such notice is given the Borrower shall, prepay the outstanding aggregate
principal amount of the Advances in whole or ratably in part, together with (i) accrued interest to
the date of such prepayment on the aggregate principal amount prepaid and (ii) (A) in the case of
any such prepayment on or prior to the first anniversary of the Amendment No. 1 Effective Date, the
Make Whole Premium, (B) in the case of any such prepayment after the first anniversary of the
Amendment No. 1 Effective Date, but on or prior to the second anniversary of the Amendment No. 1
Effective Date, a premium of 2.0% of the aggregate principal amount so prepaid, (C) in the case of
any such prepayment after the second anniversary of the Amendment No. 1 Effective Date, but on or
prior to the third anniversary of the Amendment No. 1 Effective Date, a premium of 1.0% of the
aggregate principal amount so prepaid and (D) in the case of any such prepayment after the third
anniversary of the Amendment No. 1 Effective Date, no premium; provided, however, that (x) each
partial prepayment shall be in an aggregate principal amount of $5,000,000 or an integral multiple
of $1,000,000 in excess thereof and (y) if any prepayment of a Eurodollar Rate Advance is made on a
date other than the last day of an Interest Period for such Advance, the Borrower shall also pay
any amounts owing pursuant to Section 10.04(c).

     SECTION 2.05. Interest. (a) Scheduled Interest. The Borrower shall pay interest
on the unpaid principal amount of each Advance owing to each Lender from the date of such Advance
until such principal amount shall be paid in full, at the following rates per annum:

     (i) Base Rate Advances. During such periods as such Advance is a Base Rate
Advance, a rate per annum equal at all times to the sum of (A) the Base Rate in effect from
time to time plus (B) the Applicable Margin, payable in arrears monthly first day of each
month during such periods and on the date such Base Rate Advance shall be Converted or paid
in full.

     (ii) Eurodollar Rate Advances. During such periods as such Advance is a
Eurodollar Rate Advance, a rate per annum equal at all times during each Interest Period for
such Advance to the sum of (A) the Eurodollar Rate for such Interest Period for such Advance
plus (B) the Applicable Margin, payable in arrears on the last day of such Interest Period
and, if such Interest Period has a duration of more than three months, on each day that
occurs during such Interest Period every three months from the first day of such Interest
Period and on the date such Eurodollar Rate Advance shall be Converted or paid in full.

          (b) Default Interest. To the fullest extent permitted by applicable law, upon the
occurrence and during the continuance of a Default under Section 7.01(a), (e), (f) or (g) or an
Event of Default, the Administrative Agent may, and upon the request of the Required Lenders shall,
require that the Borrower pay interest (“Default Interest”) on (i) the unpaid principal amount of
each Advance owing to each Lender, payable in arrears on the dates referred to in clause (i) or
(ii) of Section 2.05(a), as

Second Lien Credit Agreement

 

34

applicable, and on demand, at a rate per annum equal at all times to 2%
per annum above the rate per annum required to be paid on such Advance pursuant to clause (i) or
(ii) of Section 2.05(a), as applicable, and (ii) the amount of any interest, fee or other amount
payable under this Agreement or any other Loan Document to any Agent or any Lender that is not paid
when due, from the date such amount shall be due until such amount shall be paid in full, payable
in arrears on the date such amount shall be paid in full and on demand, at a rate per annum equal
at all times to 2% per annum above the rate per annum required to be paid, on Base Rate Advances
pursuant to clause (i) of Section 2.05(a); provided, however, that following the giving of notice
by the Administrative Agent to accelerate the Advances, pursuant to Section 7.01, Default Interest
shall accrue and be payable hereunder whether or not previously required by the Administrative
Agent.

          (c) Notice of Interest Period and Interest Rate. Promptly after receipt of a notice
of Conversion pursuant to Section 2.07 or a notice of selection of an Interest Period pursuant to
the terms of the definition of “Interest Period”, the Administrative Agent shall give notice to the
Borrower and each Lender of the applicable Interest Period and the applicable interest rate
determined by the Administrative Agent for purposes of clause (a)(i) or (a)(ii) above.

     SECTION 2.06. Fees. The Borrower shall pay to each Agent for its own account such fees as
may from time to time be agreed between the Borrower and such Agent.

     SECTION 2.07. Conversion of Advances. (a) Optional. The Borrower may on any
Business Day, upon notice given to the Administrative Agent not later than 11:00 A.M. (New York
City time) on the third Business Day prior to the date of the proposed Conversion and subject to
the provisions of Section 2.08, Convert all or any portion of the Advances of one Type into
Advances of the other Type; provided, however, that any Conversion of Eurodollar Rate Advances into
Base Rate Advances shall be made only on the last day of an Interest Period for such Eurodollar
Rate Advances, any Conversion of Base Rate Advances into Eurodollar Rate Advances shall be in an
amount not less than $5,000,000, and each Conversion of Advances shall be made ratably among the
Lenders in accordance with their Commitments. Each such notice of Conversion shall, within the
restrictions specified above, specify (i) the date of such Conversion, (ii) the Advances to be
Converted and (iii) if such Conversion is into Eurodollar Rate Advances, the duration of the
initial Interest Period for such Advances. Each notice of Conversion shall be irrevocable and
binding on the Borrower.

          (b) Mandatory. (i) On the date on which the aggregate unpaid principal amount of
Eurodollar Rate Advances shall be reduced, by payment or prepayment or otherwise, to less than
$5,000,000, such Advances shall automatically Convert into Base Rate Advances.

          (ii) If the Borrower shall fail to select the duration of any Interest Period for any
Eurodollar Rate Advances in accordance with the provisions contained in the definition of “Interest
Period” in Section 1.01, the Administrative Agent will forthwith so notify the Borrower and the
Lenders, whereupon each such Eurodollar Rate Advance will automatically, on the last day of the
then existing Interest Period therefor, Convert into a Base Rate Advance.

          (iii) Upon the occurrence and during the continuance of any Default, (x) each Eurodollar Rate
Advance will automatically, on the last day of the then existing Interest Period therefor, Convert
into a Base Rate Advance and (y) the obligation of the Lenders to make, or to Convert Advances
into, Eurodollar Rate Advances shall be suspended.

     SECTION 2.08. Increased Costs, Etc. (a) If, due to either (i) the introduction of or any
change (other than any change by way of imposition or increase of reserve requirements included in
the Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or regulation after
the Effective

Second Lien Credit Agreement

 

35

Date or (ii) the compliance with any guideline or request from any central bank or
other governmental authority issued or adopted after the Effective Date (whether or not having the
force of law), there shall be any increase in the cost to any Lender of agreeing to make or of
making, funding or maintaining Eurodollar Rate Advances (excluding, for purposes of this Section
2.08, any such increased costs resulting from (x) Taxes or Other Taxes (as to which Section 2.10
shall govern) and (y) changes in the basis of taxation of overall net income or overall gross
income by the United States or by the foreign jurisdiction, province or state under the laws of
which such Lender is organized or has its Applicable Lending Office or any political subdivision
thereof), then the Borrower shall from time to time, upon demand by such Lender (with a copy of
such demand to the Administrative Agent), pay to the Administrative Agent for the account of such
Lender additional amounts sufficient to compensate such Lender for such increased cost. A
certificate as to the amount of such increased cost, submitted to the Borrower by such Lender,
shall be conclusive and binding for all purposes, absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

     (b) If any Lender determines, acting reasonably, that compliance with any law or regulation or
any guideline or request from any central bank or other governmental authority issued or adopted
after the Effective Date (whether or not having the force of law) affects or would affect the
amount of capital required or expected to be maintained by such Lender or any corporation
controlling such Lender and that the amount of such capital is increased by or based upon the
existence of such Lender’s commitment to lend, then, upon demand by such Lender or such corporation
(with a copy of such demand to the Administrative Agent), the Borrower shall pay to the
Administrative Agent for the account of such Lender, from time to time as specified by such Lender,
additional amounts sufficient to compensate such Lender in the light of such circumstances, to the
extent that such Lender reasonably determines such increase in capital to be allocable to the
existence of such Lender’s commitment to lend hereunder. A certificate as to such amounts
submitted to the Borrower by such Lender shall be conclusive and binding for all purposes, absent
manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate
within 10 days after receipt thereof.

     (c) If, with respect to any Eurodollar Rate Advances, Lenders owed at least a majority of the
then aggregate unpaid principal amount thereof notify the Administrative Agent that the Eurodollar
Rate for any Interest Period for such Advances will not adequately reflect the cost to such Lenders
of making, funding or maintaining their Eurodollar Rate Advances for such Interest Period, the
Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon (i) each
such Eurodollar Rate Advance will automatically, on the last day of the then existing Interest
Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make,
or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Administrative
Agent shall notify the Borrower that such Lenders have determined that the circumstances causing
such suspension no longer exist.

     (d) Notwithstanding any other provision of this Agreement, if the introduction of or any
change in or in the interpretation of any law or regulation shall make it unlawful, or any central
bank or other governmental authority shall assert that it is unlawful, for any Lender or its
Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or
to continue to fund or maintain Eurodollar Rate Advances hereunder, then, on notice thereof and
demand therefor by such Lender to the Borrower through the Administrative Agent, (i) each
Eurodollar Rate Advance will automatically, upon such demand, Convert into a Base Rate Advance and
(ii) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances
shall be suspended until the Administrative Agent shall notify the Borrower that such Lender has
determined that the circumstances causing such suspension no longer exist.

 Second Lien Credit Agreement

 

 

36

          (e) (i) In the event that any Lender demands payment of costs or additional amounts
pursuant to this Section 2.08 or 2.10 or asserts, pursuant to Section 2.08(d) or 2.10, that it is
unlawful for such Lender to make or maintain Eurodollar Rate Advances, then such Lender shall use
reasonable efforts to designate a different Applicable Lending Office for maintaining its Loans
hereunder or to assign its right and obligations hereunder to another of its offices, branches or
affiliates if, in the judgment of such Lender, acting reasonably, such designation or assignment
(A) would eliminate or reduce amounts payable pursuant to Section 2.08 or 2.10, as the case may be,
in the future, or eliminate the basis for asserting pursuant to Section 2.08(d) that it is unlawful
for such Lender to make or maintain Eurodollar Rate Advances, as applicable, and (B) in each case,
would not subject such Lender to any unreimbursed cost or expense and would not otherwise be
disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and
expenses incurred by any Lender in connection with any such designation or assignment, (ii) in the
event that any Lender demands payment of costs or additional amounts pursuant to this Section 2.08
or Section 2.10 or asserts, pursuant to Section 2.08(d), that it is unlawful for such Lender to
make Eurodollar Rate Advances then (subject to such Lender’s right to rescind such demand or
assertion within 10 days after the notice from the Borrower referred to below) the Borrower may,
upon 20 days’ prior written notice to such Lender and the Administrative Agent, elect to cause such
Lender to assign its Advances and Commitments in full to one or more Persons selected by the
Borrower so long as (a) each such Person is reasonably satisfactory to the Administrative Agent,
(b) such Lender receives payment in full in cash of the outstanding principal amount of all
Advances made by it and all accrued and unpaid interest thereon and all other amounts due and
payable to such Lender as of the date of such assignment (including, without limitation, amounts
owing pursuant to Sections 2.08, 2.10 and 10.04) and (c) each such Person assignee agrees to accept
such assignment and to assume all obligations of such Lender hereunder in accordance with Section
10.07.

     SECTION 2.09. Payments and Computations. (a) The Borrower shall make each payment
hereunder and under the other Loan Documents, irrespective of any right of counterclaim or set-off,
not later than 1:00 P.M. (New York City time) on the day when due in U.S. dollars to the
Administrative Agent at the Administrative Agent’s Account in same day funds, with payments being
received by the Administrative Agent after such time being deemed to have been received on the next
succeeding Business Day. The Administrative Agent will promptly thereafter cause like funds to be
distributed (i) if such payment by the Borrower is in respect of principal, interest, commitment
fees or any other Obligation then payable hereunder and under the other Loan Documents to more than
one Lender, to such Lenders for the account of their respective Applicable Lending Offices ratably
in accordance with the amounts of such respective Obligations then payable to such Lenders and (ii)
if such payment by the Borrower is in respect of any Obligation then payable hereunder to one
Lender, to such Lender for the account of its Applicable Lending Office, in each case to be applied
in accordance with the terms of this Agreement.

          (b) The Borrower hereby authorizes each Lender and each of its Affiliates, if and to the
extent payment owed to such Lender is not made by the Borrower to the Administrative Agent when due
hereunder or under the other Loan Documents to charge from time to time, to the fullest extent
permitted by law, against any or all of the Borrower’s accounts with such Lender or such Affiliate
any amount so due.

          (c) All computations of interest and of fees shall be made by the Administrative Agent on the
basis of (i) with respect to Base Rate Advances, a year of 365/366 days and (ii) in all other
cases, a year of 360 days, in each case for the actual number of days (including the first day but
excluding the last day) occurring in the period for which such interest, fees or commissions are
payable. Each determination by the Administrative Agent of an interest rate, fee or commission
hereunder shall be conclusive and binding for all purposes, absent manifest error.

Second Lien Credit Agreement

 

37

          (d) Whenever any payment hereunder or under the other Loan Documents shall be stated to be due
on a day other than a Business Day, such payment shall be made on the next succeeding Business Day,
and such extension of time shall in such case be included in the computation of payment of interest
or commitment or letter of credit fee or commission, as the case may be; provided, however, that,
if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be
made in the next following calendar month, such payment shall be made on the next preceding
Business Day.

          (e) Unless the Administrative Agent shall have received notice from the Borrower prior to the
date on which any payment is due to any Lender hereunder that the Borrower will not make such
payment in full, the Administrative Agent may assume that the Borrower has made such payment in
full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon
such assumption, cause to be distributed to each such Lender on such due date an amount equal to
the amount then due such Lender. If and to the extent the Borrower shall not have so made such
payment in full to the Administrative Agent, each such Lender shall repay to the Administrative
Agent forthwith on demand such amount distributed to such Lender together with interest thereon,
for each day from the date such amount is distributed to such Lender until the date such Lender
repays such amount to the Administrative Agent, at the Federal Funds Rate.

          (f) Whenever any payment received by the Administrative Agent under this Agreement or any of
the other Loan Documents is insufficient to pay in full all amounts due and payable to the Agents
and the Lenders under or in respect of this Agreement and the other Loan Documents on any date,
such payment shall be distributed by the Administrative Agent and applied by the Agents and the
Lenders in the following order of priority:

     (i) first, to the payment of all of the fees, indemnification payments, costs and
expenses that are due and payable to the Agents (solely in their respective capacities as
Agents) under or in respect of this Agreement and the other Loan Documents on such date,
ratably based upon the respective aggregate amounts of all such fees, indemnification
payments, costs and expenses owing to the Agents on such date;

     (ii) second, to the payment of all of the indemnification payments, costs and expenses
that are due and payable to the Lenders under Sections 10.04 hereof and any similar section
of any of the other Loan Documents on such date, ratably based upon the respective aggregate
amounts of all such indemnification payments, costs and expenses owing to the Lenders on
such date;

     (iii) third, to the payment of all of the amounts that are due and payable to the
Administrative Agent and the Lenders under Sections 2.08 and 2.10 hereof on such date,
ratably based upon the respective aggregate amounts thereof owing to the Administrative
Agent and the Lenders on such date;

     (iv) fourth, to the payment of all of the accrued and unpaid interest on the
Obligations under or in respect of the Loan Documents that is due and payable to the Agents
and the Lenders under Section 2.05(b) on such date, ratably based upon the respective
aggregate amounts of all such interest owing to the Agents and the Lenders on such date;

     (v) fifth, to the payment of all of the accrued and unpaid interest on the Advances
that is due and payable to the Lenders under Section 2.05(a) on such date, ratably based
upon the respective aggregate amounts of all such interest owing to the Lenders on such
date;

Second Lien Credit Agreement

 

38

     (vi) sixth, to the payment of the principal amount of all of the outstanding Advances
that is due and payable to the Lenders on such date, ratably based upon the respective
aggregate amounts of all such principal owing to the Lenders on such date; and

     (vii) seventh, to the payment of all other Obligations of the Loan Parties owing under
or in respect of the Loan Documents that are due and payable to the Agents and the other
Secured Parties on such date, ratably based upon the respective aggregate amounts of all
such Obligations owing to the Agents and the other Secured Parties on such date.

          (g) 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.

          (h) 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.

          (i) To the fullest 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 Administrative 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.

          (j) 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.

     SECTION 2.10. Taxes. (a) Unless required by Applicable Law, any and all payments by any
Loan Party to or for the account of any Lender or any Agent hereunder or under any other Loan
Document shall be made, in accordance with Section 2.09 or the applicable provisions of such other
Loan Document, if any, free and clear of and without deduction for any and all present or future
taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding, in the case of each Lender and each Agent,

     (i) taxes that are imposed on its overall net income (and franchise taxes
imposed in lieu thereof) by the federal government state, province or foreign
jurisdiction under the laws of which such Lender or such Agent, as the case may be,
is organized or any political subdivision thereof and, in the case of each Lender,
taxes that are imposed on its overall net income (and franchise taxes imposed in
lieu thereof) by the state, province or foreign jurisdiction of such Lender’s
Applicable Lending Office or any political subdivision thereof,

     (ii) any branch profits taxes imposed by the United States of America or any
similar tax imposed by any other jurisdiction in which a Loan Party is located;

39

     (iii) present or future taxes, levies, imposts, deductions, charges or
withholdings imposed or levied by the Government of Canada or any province or
territory thereof or any Governmental Authority therein (“Canadian Taxes”) by
reason that such Lender or Agent does not deal at arm’s length with the Borrower for
the purposes of the Income Tax Act (Canada); and

     (iv) Canadian Taxes imposed or levied by reason of such Lender or Agent
carrying on business in or being connected with Canada or any province or territory
thereof otherwise than by the mere holding of its interest in the Facility or the
receipt of payments in respect thereof but for greater certainty tax imposed or
levied on a Lender under Part XIII of the Income Tax Act (Canada) shall not be
excluded solely by virtue of this Section 2.10(a)(iv);

     (v) in the case of a Lender organized under the laws of a jurisdiction other
than that which a Loan Party is resident for tax purposes (a “Foreign Lender”)
(other than an assignee pursuant to a request by the Borrower under Section
2.08(e)(i)), any deductions, withholdings or withholding tax (including tax imposed
or levied on a Lender under Part XIII of the Income Tax Act (Canada)) that is
required in respect of or imposed on amounts payable to such Lender at the time such
Lender becomes a party hereto (or designates a new Applicable Lending Office) (other
than as a result of (A) the adoption or taking effect of any law, rules, regulation
or treaty, (B) any change in any law, rules regulation or treaty or in the
administration, interpretation or application thereof by any Governmental Authority
or (C) the making or issuance of any request, guideline or directive (whether or not
having the force of law) by any Governmental Authority , in each case occurring
after the date such Lender becomes a party hereto (or designates a new Applicable
Lending Office)), except to the extent that such Lender (or its assignor, if any)
was entitled, at the time of designation of a new Applicable Lending Office (or
assignment) to receive additional amounts from the applicable Loan Party with
respect to such withholding tax pursuant to this Section 2.10 (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect
of payments hereunder or under any other Loan Document being hereinafter referred to
as “Taxes”).

     (vi) If any Loan Party shall be required by law to deduct any Taxes from or in
respect of any sum payable hereunder or under any other Loan Document to any Lender
or any Agent, the sum payable by such Loan Party shall be increased as may be
necessary so that after such Loan Party and the Administrative Agent have made all
required deductions (including deductions applicable to additional sums payable
under this Section 2.10) such Lender or such Agent, as the case may be, receives an
amount equal to the sum it would have received had no such deductions been made,
such Loan Party shall make all such deductions and such Loan Party shall pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable law.

          (b) In addition, each Loan Party shall pay any present or future stamp, documentary, excise,
property, intangible, mortgage recording or similar taxes, charges or levies that arise from any
payment made by such Loan Party hereunder or under any other Loan Documents or from the execution,
delivery or registration of, performance under, or otherwise with respect to, this Agreement, or
the other Loan Documents (hereinafter referred to as “Other Taxes”).

          (c) The Loan Parties shall indemnify each Lender and each Agent for and hold them harmless
against the full amount of Taxes and Other Taxes imposed or asserted by any jurisdiction on

Second Lien Credit Agreement

 

40

amounts
payable by any Loan Party to or for the account of such Lender or Agent hereunder, or under any
other Loan Document (including any amounts payable under this Section 2.10) imposed on or paid by
such Lender or such Agent (as the case may be) and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto. This indemnification shall be made within 30
days from the date such Lender or such Agent (as the case may be) makes written demand therefor.

          (d) Within 30 days after the date of any payment of Taxes, the appropriate Loan Party shall
furnish to the Administrative Agent, at its address referred to in Section 10.02, the original or a
certified copy of a receipt evidencing such payment, to the extent such a receipt is issued
therefor, or other written proof of payment thereof that is reasonably satisfactory to the
Administrative Agent. In the case of any payment hereunder or under the other Loan Documents by or
on behalf of a Loan Party through an account or branch outside the United States or by or on behalf
of a Loan Party by a payor that is not a United States Person, if such Loan Party determines that
no Taxes are payable in respect thereof, such Loan Party shall furnish, or shall cause such payor
to furnish, to the Administrative Agent, at such address, an opinion of counsel acceptable to the
Administrative Agent stating that such payment is exempt from Taxes. For purposes of this
subsection (d) of this Section 2.10, the terms “United States” and “United States Person” shall
have the meanings specified in Section 7701 of the Internal Revenue Code.

          (e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax
under the law of the jurisdiction in which a Loan Party, is resident for tax purposes, with respect
to payments hereunder or under any other Loan Document shall deliver to such Loan Party (with a
copy to the Administrative Agent), as reasonably requested by a Loan Party or the Administrative
Agent, such properly completed and executed documentation prescribed by applicable law as will
permit such payments to be made without withholding or at a reduced rate of withholding; provided
however (1) that such forms would not, in the good faith judgment of such Lender, require such
Lender to disclose any confidential or proprietary information, (2) such Lender is legally entitled
to complete, execute and deliver such forms, certificates or other documents and (3) the
completion, execution or delivery of such forms, certificates or other documents would not, in the
good faith judgment of the Lender, result in the imposition on the Lender of any additional
material legal or regulatory burdens, any additional material out-of-pocket costs not indemnified
hereunder, or be otherwise materially disadvantageous to such Lender.

     SECTION 2.11. Sharing of Payments, Etc. If any Lender shall obtain at any time any
payment (whether voluntary, involuntary, through the exercise of any right of set-off, or
otherwise, other than as a result of an assignment pursuant to Section 10.07) (a) on account of
Obligations due and payable to such Lender hereunder and under the other Loan Documents at such
time in excess of its ratable share (according to the proportion of (i) the amount of such
Obligations due and payable to such Lender at such time to (ii) the aggregate amount of the
Obligations due and payable to all Lenders hereunder and under the other Loan Documents at such
time) of payments on account of the Obligations due and payable to all Lenders hereunder and under
the other Loan Documents at such time obtained by all the Lenders at such time or (b) on account of
Obligations owing (but not due and payable) to such Lender hereunder and under the other Loan
Documents at such time in excess of its ratable share (according to the proportion of (i) the
amount of such Obligations owing to such Lender at such time to (ii) the aggregate amount of the
Obligations owing (but not due and payable) to all Lenders hereunder and under the other Loan
Documents at such time) of payments on account of the Obligations owing (but not due and payable)
to all Lenders hereunder and under the other Loan Documents at such time obtained by all of the
Lenders at such time, such Lender shall forthwith
purchase from the other Lenders such interests or participating interests in the Obligations due
and payable or owing to them, as the case may be, as shall be necessary to cause such purchasing
Lender to share the excess payment ratably with each of them; provided, however, that if all or any
portion of such excess payment is thereafter recovered from such purchasing Lender,

Second Lien Credit Agreement

 

41

such purchase
from each other Lender shall be rescinded and such other Lender shall repay to the purchasing
Lender the purchase price to the extent of such Lender’s ratable share (according to the proportion
of (i) the purchase price paid to such Lender to (ii) the aggregate purchase price paid to all
Lenders) of such recovery together with an amount equal to such Lender’s ratable share (according
to the proportion of (i) the amount of such other Lender’s required repayment to (ii) the total
amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by
the purchasing Lender in respect of the total amount so recovered. Upon receipt by the
Administrative Agent of notice, if any, of any such purchase (or subsequent rescission), the
Administrative Agent shall promptly give notice thereof to the Borrower. The Loan Parties agree
that any Lender so purchasing an interest or participating interest from another Lender pursuant to
this Section 2.11 may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such interest or participating interest, as the
case may be, as fully as if such Lender were the direct creditor of the Loan Parties in the amount
of such interest or participating interest, as the case may be.

     SECTION 2.12. Use of Proceeds. The proceeds of the Term Advances shall be available to
(and the Borrower agrees that it shall use such proceeds solely to) pay transaction fees and for
general corporate purposes including, without limitation, acquisitions and the funding of
development activities.

     SECTION 2.13. Evidence of Debt. (a) Each Lender shall maintain in accordance with its
usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender
resulting from each Advance owing to such Lender from time to time, including the amounts of
principal and interest payable and paid to such Lender from time to time hereunder. The Borrower
agrees that upon notice by any Lender to the Borrower (with a copy of such notice to the
Administrative Agent) to the effect that a promissory note or other evidence of indebtedness is
required or appropriate in order for such Lender to evidence (whether for purposes of pledge,
enforcement or otherwise) the Advances owing to, or to be made by, such Lender, the Borrower shall
promptly execute and deliver to such Lender, with a copy to the Administrative Agent, a Note in
substantially the form of Exhibit A hereto, payable to the order of such Lender in a principal
amount equal to the outstanding Advances of such Lender. All references to Notes in the Loan
Documents shall mean Notes, if any, to the extent issued hereunder.

          (b) The Administrative Agent shall maintain accounts in which it will record (i) the Type of
Advances comprising each Borrowing and, if appropriate, the Interest Period applicable thereto,
(ii) the amount of any principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder, and (iii) the amount of any sum received by the Administrative
Agent from the Borrower hereunder and each Lender’s share thereof.

          (c) Entries made in good faith by the Administrative Agent pursuant to subsection (b) above,
and by each Lender in its account or accounts pursuant to subsection (a) above, shall be prima
facie evidence of the amount of principal and interest due and payable or to become due and payable
from the Borrower to each Lender, under this Agreement, absent manifest error; provided, however,
that the failure of the Administrative Agent or such Lender to make an entry, or any finding that
an entry is incorrect, in such account or accounts shall not limit or otherwise affect the
obligations of the Borrower under this Agreement.

incorporation or is a partnership or trust validly existing under the laws of the Province of
Alberta; each is duly registered in all other jurisdictions where the nature of its property or

contemplated by the Loan Documents.

          (b) Authority. The Borrower and each of its Subsidiaries has full power, legal right

delivery of this Agreement or performance of any obligation pursuant thereto requires or will
require, pursuant to applicable law now in effect, any approval or consent of any Governmental

agreement to which the Borrower or any of its Subsidiaries is a party or by which they or their
properties or assets are bound, the contravention of which would have or would reasonably be
expected to have a Material Adverse Effect. The Loan Documents when executed and delivered will
constitute valid and legally binding obligations of the Borrower and each Subsidiary which is a
party thereto enforceable against each such party in accordance with their respective terms,
subject to applicable bankruptcy, insolvency and other laws of general application limiting the
enforceability of creditors’ rights and to the fact that equitable remedies are only available in

continuing which has had or would reasonably be expected to have a Material Adverse Effect.

reasonable assumptions at the date of preparation, and, in all other cases, true, complete
and correct in all material respects as of the respective dates thereof; and

of the respective dates thereof.

          (m) Absence of Litigation. There are no actions, suits or proceedings pending or, to
the knowledge of the Borrower, threatened against or affecting the Borrower or any of its
Subsidiaries, their property or any of their undertakings and assets, at law, in equity or before
any arbitrator or before or by any Governmental Authority having jurisdiction in the premises in

the Borrower and its Subsidiaries to Governmental Authorities have been made, are currently up to
date and there are no outstanding arrears, other than those which are being contested by Permitted

Borrower, its Subsidiaries and their respective properties, assets and undertakings taken as
a whole comply in all respects and the businesses, activities and operations of same and the
use of such properties, assets and undertakings and the processes and undertakings performed
thereon comply in all respects with all Environmental Laws except to the extent that failure
to so comply would not have and would not reasonably be expected to have a Material Adverse
Effect; further, the Borrower does not know, and has no reasonable grounds to know, of any
facts which result in
or constitute or are likely to give rise to non-compliance with any Environmental Laws,
which facts or non-compliance have or would reasonably be expected to have a Material
Adverse Effect.

     (ii) The Borrower has not received written notice and, except as previously disclosed
to the Administrative Agent in writing, has no knowledge after due inquiry, of any facts
which could give rise to any notice of non-compliance with any Environmental Laws, which

not received any notice that the Borrower or any of its Subsidiaries is a potentially
responsible party for a federal, provincial, regional, municipal or local clean up or
corrective action in connection with their respective properties, assets and undertakings
where such clean up or corrective action has or would reasonably be expected to have a

Subsidiary Guarantors listed on Schedule II hereto.

credit for the purpose of purchasing or carrying Margin Stock, and no proceeds of any Advance will
be used to purchase or carry any Margin Stock or to extend credit to others for the purpose of
purchasing or carrying any Margin Stock.

          (u) Investment Company Act; Public Utility Holding Company Act. Neither any Loan

ARTICLE VI

SECURITY

     SECTION 6.01. Security on all Assets. (a) The Obligations of the Loan Parties under
the Loan Documents (the “Secured Obligations”) shall be secured, equally and rateably, by perfected
Security Interests on, to and against all present and future property, assets and undertaking of
the Borrower and each of its Material Subsidiaries, second in priority only to (i) the Security
Interests in favor of the lenders or the First Lien Agent under the First Lien Facility, (ii)
Permitted Encumbrances existing as of the Effective Date and (iii) Permitted Encumbrances that are
Security Interests that by the operation of law are granted priority ahead of all other Security
Interests existing over the property by which they are secured.

          (b) The Borrower shall execute and deliver Collateral Documents in the forms of Exhibits J-1,
J-2 and J-3 annexed hereto and shall cause each of its Material Subsidiaries to execute and deliver
a Subsidiary Guaranty and Collateral Documents in the forms of Exhibits J-4, J-5 and J-6 annexed
hereto, in each case with such modifications and insertions as may be required by the
Administrative Agent, acting reasonably.

          (c) The Borrower (i) shall, as soon as reasonably practicable, give written notice to the
Administrative Agent of the acquisition, creation or existence of each Material Subsidiary created
or acquired after the date hereof, together with such other information as the Collateral Agent may
reasonably require, and (ii) shall promptly, and in any event within 10 Business Days of such
acquisition, creation or existence, cause each new Material Subsidiary to promptly execute and
deliver to the Administrative Agent a Subsidiary Guaranty and the Collateral Documents contemplated
hereby (together with a certified copy of its constating documents and a legal opinion in form and
substance satisfactory to the Administrative Agent, acting reasonably).

          (d) The Borrower shall ensure that at all times, at least 95% of the Consolidated assets of
the Borrower shall be legally, beneficially and directly owned by the Borrower and Material
Subsidiaries which have executed and delivered a Subsidiary Guaranty and Collateral Documents

Second Lien Credit Agreement

 

59

hereunder; and if at any time less than 95% of the Consolidated assets of the Borrower shall be
legally, beneficially and directly owned by the Borrower and Material Subsidiaries which have
executed and delivered a Subsidiary Guaranty and Collateral Documents hereunder, the Borrower shall
promptly, and in any event within 10 Business Days after any such occurrence, designate another
Subsidiary which is not then a Material Subsidiary to be a Designated Material Subsidiary pursuant
hereto to the extent required to ensure that after such designation, 95% or more of the
Consolidated assets of the Borrower shall be legally, beneficially and directly owned by the
Borrower and Material Subsidiaries which have executed and delivered a Subsidiary Guaranty and
Collateral Documents hereunder.

          The Borrower shall from time to time, by notice in writing to the Administrative Agent
(together with reasonable particulars which demonstrate compliance with the foregoing covenant), be
entitled to designate that either:

     (i) a Subsidiary which is not a Material Subsidiary shall become a Designated Material
Subsidiary; or

     (ii) a Designated Material Subsidiary shall cease to be a Material Subsidiary,

provided that the Borrower shall not be entitled to designate that a Designated Material Subsidiary
shall cease to be a Material Subsidiary if:

     (iii) a Default or an Event of Default has occurred and is continuing;

     (iv) a Default or an Event of Default would result from or exist immediately after such
a designation; or

     (v) such Designated Material Subsidiary falls within part (a), (b), (c) or (d) of the
definition of “Material Subsidiary”.

In order to give effect to the foregoing provisions of Section 6.01(c) and this Section 6.01(d),
the Borrower shall cause any Material Subsidiary that becomes a Designated Material Subsidiary to
promptly execute and deliver a Subsidiary Guaranty and Collateral Documents to the Administrative
Agent (together with a certified copy of its constating documents and a legal opinion in form and
substance satisfactory to the Administrative Agent, acting reasonably).

          (e) In addition to the Collateral Documents described in subsections (a) and (b) of this
Section 6.01, the Borrower shall execute and deliver, or shall cause to be executed and delivered,
all such guarantees and mortgages, debentures, pledge agreements, assignments and other security
agreements as may be required by the Required Lenders, acting reasonably (each in form and
substance satisfactory to the Required Lenders) in order to, or to more effectively, charge in
favor of the Collateral Agent or grant Security Interests in favor of the Collateral Agent on and
against all of the undertaking, assets and property (real or personal, tangible or intangible,
present or future and of whatsoever nature and kind) of the Borrower and its Material Subsidiaries
as continuing collateral security for the payment and performance by the Borrower of all
Obligations. Notwithstanding the foregoing, and for greater certainty, the Borrower and its
Subsidiaries shall not be obligated by this Section 6.01(e) to provide fixed charges in any
jurisdiction in which a floating charge may be provided on or against their P&NG Rights or P&NG
Leases unless the Borrower or any of its Subsidiaries provides such a charge to secure the First
Lien Obligations (but this sentence shall not restrict the registration, recording or filing of any
other Security otherwise provided by the Borrower and its Subsidiaries in accordance with the terms
hereof).

Second Lien Credit Agreement

 

60

     SECTION 6.02. Registration. The Borrower shall, at its expense, register, file or
record the Collateral Documents in all offices where such registration, filing or recording is
necessary or of advantage to the creation, perfection and preserving of the security applicable to
it; provided that the Borrower (as opposed to the Administrative Agent and the Lenders or another
Administrative Agent thereof on their behalf, in such case at the expense of the Administrative
Agent and the Lenders except during the continuance of a Default or Event of Default and except
where requested by the Administrative Agent, acting reasonably) shall not be obligated to register,
file or record the Collateral Documents at any land registry offices (including any mines and
minerals registration) unless and until the Administrative Agent (acting reasonably) requests such
registration in writing. The Borrower shall amend and renew such registrations, filings and
recordings from time to time as and when required to keep them in full force and effect or to
preserve the priority established by any prior registration, filing or recording thereof.

     SECTION 6.03. Forms. The forms of Collateral Documents shall have been or be prepared
based upon the laws of Canada and Alberta applicable thereto in effect at the date hereof. The
Administrative Agent shall have the right to require that:

     (a) any such Collateral Document be amended to the extent desirable in the reasonable
judgment of the Collateral Agent to reflect any changes in such laws, whether arising as a
result of statutory amendments, court decisions or otherwise, in order to confer upon the
Collateral Agent the Security Interests intended to be created thereby,

     (b) in the event that the Borrower or any Subsidiary Guarantor owns or acquires assets
in the United States of America, that the forms of Collateral Documents applicable to such
assets be amended or replaced to be based on the laws of the United States of America and
any applicable laws of the states thereof in order to confer upon the Collateral Agent the
Security Interests intended to be created thereby,

     (c) any such Collateral Document be amended in accordance with the provisions of the
Intercreditor Agreement, reflect any changes to the document relating to collateral securing
the First Lien Facility, so long as such changes are not adverse to the Lenders hereunder,
and

     (d) the Borrower and its Subsidiaries execute and deliver to the Administrative Agent
such other and further debentures, mortgages, trust deeds, assignments and security
agreements as may be reasonably required to ensure the Collateral Agent holds, subject to
Permitted Encumbrances, perfected Security Interests on, to and against all of the property,
assets and undertakings of the Borrower and each of its Material Subsidiaries, second in
priority only to the Security Interests in favor of the lenders or the First Lien Agent
under the First Lien Facility on, to and against such property, assets and undertakings of
the Borrower and each such Material Subsidiary granted by the Borrower to secure the First
Lien Obligations;

except that in no event shall the Administrative Agent require that the foregoing clauses (a), (b)
or (d) above be effected if the result thereof would be to grant the Collateral Agent or the
Lenders greater rights than is otherwise contemplated herein or therein.

     SECTION 6.04. Continuing Security. Each item of Collateral and each Collateral Document shall for all purposes be treated as a
separate and continuing collateral security and shall be deemed to have been given in addition to
and not in place of any other item of Collateral or other Collateral Document or any other security
now held or hereafter acquired by the Collateral Agent or the Lenders. No Collateral Document
shall be merged or be deemed to have been merged in or by this Agreement or any documents,
instruments or acknowledgements delivered hereunder, or any simple contract debt or any judgment,
and any realization of or steps taken under or pursuant to any security, instrument or

Second Lien Credit Agreement

 

61

agreement shall be independent of and not create a merger with any other right available to the Lenders or
the Collateral Agent under any security, instruments or agreements held by it or at law or in
equity.

     SECTION 6.05. Effectiveness. The Collateral Documents and the security created by any
other Loan Document constituted or required to be created shall be effective, and the undertakings
as to the Collateral herein or in any other Document shall be continuing, whether any Advances are
then outstanding or any amounts thereby secured or any part thereof shall be owing before or after,
or at the same time as, the creation of such Security Interests or before or after or upon the date
of execution of any amendments to this Agreement.

     SECTION 6.06. Secured Hedge Agreements of Former Lenders. If a Lender ceases to be a
Lender under this Agreement (a “Former Lender”), all Financial Instruments entered into by such
Former Lender and its Affiliates while such Former Lender was a Lender shall remain secured by the
Collateral (equally and rateably) to the extent that such Financial Instruments were secured by the
Collateral prior to such Lender becoming a Former Lender and, subject to the following provisions
of this Section 6.06 and unless the context otherwise requires, all references herein to “Secured
Hedge Agreements” shall include such Financial Instruments entered into by Former Lenders and their
Affiliates and all references herein to “Secured Parties” shall include such Former Lenders and
their Affiliates. For certainty, any Financial Instruments entered into with a Former Lender or an
Affiliate thereof after the Former Lender has ceased to be a Lender shall not be secured by the
Collateral. Notwithstanding the foregoing, no Former Lender or any Affiliate thereof shall have
any right to cause or require the enforcement of any rights with respect to the Collateral or have
any right to participate in any decisions relating to the Collateral, including any decisions
relating to the enforcement or manner of enforcement of rights in respect of the Collateral or
decisions relating to any amendment to, waiver under, release of or other dealing with all or any
part of the Collateral Documents; for certainty, the sole right of a Former Lender and its
Affiliates with respect to the Collateral is to share, on a pari passu basis, in any proceeds of
realization and enforcement of rights with respect to the Collateral.

become due and payable or (ii) the Borrower shall fail to pay any interest on any Advance,

Section 5.02(e) is caused by existing Debt described in clause (b) of the definition of
“Permitted Debt” no longer being permitted as a direct result of a decrease in the PDP PV-10
Value, then an Event of Default shall not occur unless the Borrower and its Subsidiaries
have not remedied or cured such failure within 20 Business Days after receipt by the
Borrower of the Engineering Report that reflects such decrease in PDP PV-10 Value;

ARTICLE VIII

THE AGENTS

     SECTION 8.01. Authorization and Action. (a) Each Lender (in its capacities as a Lender
and on behalf of itself and its Affiliates as potential Hedge Banks) hereby appoints and authorizes
each Agent to take such action as agent on its behalf and to exercise such powers and discretion
under this Agreement and the other Loan Documents as are delegated to such Agent by the terms
hereof and thereof, together with such powers and discretion as are reasonably incidental thereto.
As to any matters not expressly provided for by the Loan Documents (including, without limitation,
enforcement or collection of the Obligations of the Loan Parties under the Loan Documents), no
Agent shall be required to exercise any discretion or take any action, but 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 Required Lenders, and such instructions shall be binding upon all
Lenders, all Hedge Banks and all holders of Notes; provided, however, that no Agent shall be
required to take any action that exposes such Agent to personal liability or that is contrary to
this Agreement or applicable law.

          (b) In furtherance of the foregoing, each Lender (in its capacities as a Lender and on behalf
of itself and its Affiliates as potential Hedge Banks) hereby appoints and authorizes the
Collateral Agent to act as the agent of such Lender for purposes of acquiring, holding and
enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the
Secured Obligations, together with such powers and discretion as are reasonably incidental thereto.
In this connection, the Collateral Agent (and any Supplemental Collateral Agents appointed by the
Collateral Agent pursuant to Section 8.01(c) for purposes of holding or enforcing any Lien on the
Collateral (or any portion thereof) granted under the Collateral Documents, or for exercising any
rights or remedies thereunder at the direction of the Collateral Agent), shall be entitled to the
benefits of this Article VIII (including, without limitation, Section 8.05 as though any such
Supplemental Collateral Agents were “Agents” under the Loan Documents) as if set forth in full
herein with respect thereto.

          (c) Any Agent may execute any of its duties under this Agreement or any other Loan Document
(including for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof)
granted under the Collateral Documents or of exercising any rights and remedies thereunder at the
direction of the Collateral Agent) by or through agents, employees or attorneys-in-fact and shall
be entitled to advice of counsel and other consultants or experts concerning all matters pertaining
to such duties. The Collateral Agent may also from time to time, when the Collateral Agent deems
it to be necessary or desirable, appoint one or more trustees, co-trustees, collateral co-agents,
collateral subagents or attorneys-in-fact (each, a “Supplemental Collateral Agent”) with respect to
all or any part of the Collateral; provided, however, that no such Supplemental Collateral Agent
shall be authorized to take any action with respect to any Collateral unless and except to the
extent expressly authorized in writing by the Collateral Agent. Should any instrument in writing
from the Borrower or any other Loan Party be required by any Supplemental Collateral Agent so
appointed by the Collateral Agent to more fully or
certainly vest in and confirm to such Supplemental Collateral Agent such rights, powers,
privileges and duties, the Borrower shall, or shall cause such Loan Party to, execute, acknowledge
and deliver any and all such instruments promptly upon request by the Collateral Agent. If any
Supplemental Collateral Agent, or successor thereto, shall die, become incapable of acting, resign
or be removed, all rights, powers, privileges and duties of such Supplemental Collateral Agent, to
the extent permitted by law, shall automatically vest in and be exercised by the Collateral Agent
until the appointment of a new Supplemental Collateral Agent. No Agent shall be responsible for
the negligence or misconduct of any agent, attorney-in-fact or Supplemental Collateral Agent that
it selects in accordance with the foregoing provisions of this Section 8.01(c) in the absence of
such Agent’s gross negligence or willful misconduct.

Second Lien Credit Agreement

 

66

     SECTION 8.02. Agents’ Reliance, Etc. Neither any Agent nor any of their respective
directors, officers, agents or employees shall be liable for any action taken or omitted to be
taken by it or them under or in connection with the Loan Documents, except for its or their own
gross negligence or willful misconduct. Without limitation of the generality of the foregoing,
each Agent: (a) may consult with legal counsel (including counsel for any Loan Party), 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; (b) makes no warranty or representation to any Lender and shall not be responsible to
any Lender for any statements, warranties or representations (whether written or oral) made in or
in connection with the Loan Documents; (c) shall not have any duty to ascertain or to inquire as to
the performance, observance or satisfaction of any of the terms, covenants or conditions of any
Loan Document on the part of any Loan Party or the existence at any time of any Default under the
Loan Documents or to inspect the property (including the books and records) of any Loan Party; (d)
shall not be responsible to any Lender for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of, or the perfection or priority of any lien or security
interest created or purported to be created under or in connection with, any Loan Document or any
other instrument or document furnished pursuant thereto; and (e) shall incur no liability under or
in respect of any Loan Document by acting upon any notice, consent, certificate or other instrument
or writing (which may be by telegram, telecopy or telex) believed by it to be genuine and signed or
sent by the proper party or parties.

     SECTION 8.03. CS and Affiliates. With respect to its Commitments, the Advances made by it
and any Notes issued to it, CS shall have the same rights and powers under the Loan Documents as
any other Lender and may exercise the same as though each were not an Agent; and the term “Lender”
or “Lender” shall, unless otherwise expressly indicated, include CS in its individual capacity. CS
and its respective affiliates may accept deposits from, lend money to, act as trustee under
indentures of, accept investment banking engagements from and generally engage in any kind of
business with, any Loan Party, any of its Subsidiaries and any Person that may do business with or
own securities of any Loan Party or any such Subsidiary, all as if CS were not an Agent and without
any duty to account therefor to the Lenders. No Agent shall have any duty to disclose any
information obtained or received by it or any of its Affiliates relating to any Loan Party or any
of its Subsidiaries to the extent such information was obtained or received in any capacity other
than as such Agent.

     SECTION 8.04. Lender Credit Decision. Each Lender acknowledges that it has, independently
and without reliance upon any Agent or any other Lender and based on the financial statements
referred to in Section 4.01 and such other documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon any
Agent or any other Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking action under this
Agreement.

     SECTION 8.05. Indemnification. (a) Each Lender severally agrees to indemnify each Agent
(to the extent not promptly reimbursed by the Borrower) from and against such Lender’s ratable
share (determined as provided below) of any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever that may be imposed on, incurred by, or asserted against such Agent in any way relating
to or arising out of the Loan Documents or any action taken or omitted by such Agent under the Loan
Documents (collectively, the “Indemnified Costs”); provided, however, 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 such Agent’s gross negligence or
willful misconduct as found in a final, non-appealable judgment by a court of competent
jurisdiction. Without limitation of the foregoing, each Lender agrees to reimburse each Agent
promptly upon demand for its ratable share of any costs and expenses (including,

Second Lien Credit Agreement

 

67

without
limitation, fees and expenses of counsel) payable by the Borrower under Section 10.04, to the
extent that such Agent is not promptly reimbursed for such costs and expenses by the Borrower. In
the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this
Section 8.05 applies whether any such investigation, litigation or proceeding is brought by any
Lender or any other Person.

          (b) For purposes of this Section 8.05, each Lender’s ratable share of any amount shall be
determined, at any time, according to the sum of (i) the aggregate principal amount of the Advances
outstanding at such time and owing to such Lender and (ii) the aggregate unused portions of such
Lender’s Commitments at such time. The failure of any Lender to reimburse any Agent promptly upon
demand for its ratable share of any amount required to be paid by the Lender to such Agent, as
provided herein shall not relieve any other Lender of its obligation hereunder to reimburse such
Agent for its ratable share of such amount, but no Lender shall be responsible for the failure of
any other Lender to reimburse such Agent for such other Lender’s ratable share of such amount.
Without prejudice to the survival of any other agreement of any Lender hereunder, the agreement and
obligations of each Lender contained in this Section 8.05 shall survive the payment in full of
principal, interest and all other amounts payable hereunder and under the other Loan Documents.

     SECTION 8.06. Successor Agents. Any Agent may resign  at any time by giving
written notice thereof to the Lenders and the Borrower and may be removed at any time with or
without cause by the Required Lenders; provided, however, that any removal of the Administrative
Agent will not be effective until it has also been replaced as Collateral Agent and released from
all of its obligations in respect thereof. Upon any such resignation or removal, the Required
Lenders shall have the right to appoint a successor Agent. If no successor Agent shall have been
so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days
after the retiring Agent’s giving of notice of resignation or the Required Lenders’ removal of the
retiring Agent, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent,
which shall be a commercial bank organized under the laws of the United States or of any State
thereof and having a combined capital and surplus of at least $250,000,000. Upon the acceptance of
any appointment as Agent hereunder by a successor Agent and, in the case of a successor Collateral
Agent, upon the execution and filing or recording of such financing statements, or amendments
thereto, and such amendments or supplements to the Mortgages Collateral Documents, and such other
instruments or notices, as may be necessary or desirable, or as the Required Lenders may request,
in order to continue the perfection of the Liens granted or purported to be granted by the
Collateral Documents, such successor Agent shall succeed to and become vested with all the rights,
powers, discretion, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations under the Loan
Documents. If within 45 days after written notice is given of the retiring Agent’s resignation or
removal under this Section 8.06 no successor Agent shall have been appointed and shall have
accepted such appointment, then on such 45th day (a) the retiring Agent’s resignation or
removal shall become effective, (b) the retiring Agent shall thereupon be discharged from its
duties and obligations under the Loan Documents and (c) the Required Lenders shall thereafter
perform all duties of the retiring Agent under the Loan Documents until such time, if any, as the
Required Lenders appoint a successor Agent as provided above. After any retiring Agent’s
resignation or removal hereunder as Agent shall have become effective, the provisions of this
Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while
it was Agent.

ARTICLE IX

GUARANTY

     SECTION 9.01. Guaranty; Limitation of Liability. (a) Each Guarantor, jointly and
severally, hereby absolutely, unconditionally and irrevocably guarantees the punctual payment when
due, whether at

Second Lien Credit Agreement

 

68

scheduled maturity or on any date of a required prepayment or by acceleration,
demand or otherwise, of all Obligations of each other Loan Party now or hereafter existing under or
in respect of the Loan Documents (including, without limitation, any extensions, modifications,
substitutions, amendments or renewals of any or all of the foregoing Obligations), whether direct
or indirect, absolute or contingent, and whether for principal, interest, premiums, fees,
indemnities, early termination amounts, contract causes of action, costs, expenses or otherwise
(such Obligations being the “Guaranteed Obligations”), and agrees to pay all costs and expenses of
each Agent and each Lender in connection with the enforcement of any rights under this Subsidiary
Guaranty or any other Loan Document, whether in any action, suit or litigation, or bankruptcy,
insolvency or other similar proceeding affecting creditors’ rights generally (including, without
limitation, the reasonable fees and expenses of counsel for the Administrative Agent and each
Lender with respect thereto determined, in respect of actions in a court in Canada, on a solicitor
and his own client full indemnity basis). Without limiting the generality of the foregoing, each
Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed
Obligations and would be owed by any other Loan Party to any Secured Party under or in respect of
the Loan Documents but for the fact that they are unenforceable or not allowable due to the
existence of a bankruptcy, reorganization or similar proceeding involving such other Loan Party.

          (b) Each Guarantor, and by its acceptance of this Subsidiary Guaranty, the Administrative
Agent and each other Secured Party, hereby confirms that it is the intention of all such Persons
that this Subsidiary Guaranty and the Obligations of each Subsidiary Guarantor hereunder not
constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform
Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or
state law to the extent applicable to this Subsidiary Guaranty and the Obligations of each
Subsidiary Guarantor hereunder. To effectuate the foregoing intention, the Administrative Agent,
the other Secured Parties and the Guarantors hereby irrevocably agree that the Obligations of each
Subsidiary Guarantor under this Subsidiary Guaranty at any time shall be limited to the maximum
amount as will result in the Obligations of such Guarantor under this Subsidiary Guaranty not
constituting a fraudulent transfer or conveyance.

          (c) Each Guarantor hereby unconditionally and irrevocably agrees that in the event any payment
shall be required to be made to any Secured Party under this Subsidiary Guaranty or any other
guaranty, such Guarantor will contribute, to the maximum extent permitted by law, such amounts to
each other Guarantor and each other guarantor so as to maximize the aggregate amount paid to the
Secured Parties under or in respect of the Loan Documents.

     SECTION 9.02. Guaranty Absolute. Each Guarantor guarantees that the Guaranteed Obligations
will be paid strictly in accordance with the terms of the Loan Documents, regardless of any law,
regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or
the rights of any Secured Party with respect thereto. The Obligations of each Guarantor under or
in respect of this Subsidiary Guaranty are independent of the Guaranteed Obligations or any other
Obligations of any other Loan Party under or in respect of the Loan Documents, and a separate
action or actions may be brought and prosecuted against each Guarantor to enforce this Subsidiary
Guaranty, irrespective of whether any action is brought against the Borrower or any other Loan
Party or whether the Borrower or any other Loan Party is joined in any such action or actions. The
liability of each Guarantor under this Subsidiary Guaranty shall be irrevocable, absolute and
unconditional irrespective of, and each Guarantor hereby irrevocably waives any defenses it may now
have or hereafter acquire in any way relating to, any or all of the following:

          (a) any lack of validity or enforceability of any Loan Document or any agreement or instrument
relating thereto;

Second Lien Credit Agreement

 

69

          (b) any change in the time, manner or place of payment of, or in any other term of, all or any
of the Guaranteed Obligations or any other Obligations of any other Loan Party under or in respect
of the Loan Documents, or any other amendment or waiver of or any consent to departure from any
Loan Document, including, without limitation, any increase in the Guaranteed Obligations resulting
from the extension of additional credit to any Loan Party or any of its Subsidiaries or otherwise
or any increase in interest rates or fees;

          (c) any taking, exchange, release or non-perfection of any Collateral or any other collateral,
or any taking, release or amendment or waiver of, or consent to departure from, any other guaranty,
for all or any of the Guaranteed Obligations;

          (d) any manner of application of Collateral or any other collateral, or proceeds thereof, to
all or any of the Guaranteed Obligations, or any manner of sale or other disposition of any
Collateral or any other collateral for all or any of the Guaranteed Obligations or any other
Obligations of any Loan Party under the Loan Documents or any other assets of any Loan Party or any
of its Subsidiaries;

          (e) any change, restructuring or termination of the corporate structure or existence of any
Loan Party or any of its Subsidiaries;

          (f) any failure of any Secured Party to disclose to any Loan Party any information relating to
the business, condition (financial or otherwise), operations, performance, properties or prospects
of any other Loan Party now or hereafter known to such Secured Party (each Guarantor waiving any
duty on the part of the Secured Parties to disclose such information);

          (g) the failure of any other Person to execute or deliver this Agreement, any Guaranty
Supplement or any other guaranty or agreement or the release or reduction of liability of any
Guarantor or other guarantor or surety with respect to the Guaranteed Obligations; or

          (h) any other circumstance (including, without limitation, any statute of limitations) or any
existence of or reliance on any representation by any Secured Party that might otherwise constitute
a defense available to, or a discharge of, any Loan Party or any other guarantor or surety.

This Subsidiary Guaranty shall continue to be effective or be reinstated, as the case may be, if at
any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be
returned by any Secured Party or any other Person upon the insolvency, bankruptcy or reorganization
of the Borrower or any other Loan Party or otherwise, all as though such payment had not been made.

     SECTION 9.03. Waivers and Acknowledgments. (a) Each Guarantor hereby unconditionally and
irrevocably waives promptness, diligence, notice of acceptance, presentment, demand for
performance, notice of nonperformance, default, acceleration, protest or dishonor and any other
notice with respect to any of the Guaranteed Obligations and this Guaranty and any requirement that
any Secured Party protect, secure, perfect or insure any Lien or any property subject thereto or
exhaust any right or take any action against any Loan Party or any other Person or any Collateral.

          (b) Each Guarantor hereby unconditionally and irrevocably waives any right to revoke this
Subsidiary Guaranty and acknowledges that this Subsidiary Guaranty is continuing in nature and
applies to all Guaranteed Obligations, whether existing now or in the future.

          (c) Each Guarantor hereby unconditionally and irrevocably waives (i) any defense arising by
reason of any claim or defense based upon an election of remedies by any Secured Party that in any
manner impairs, reduces, releases or otherwise adversely affects the subrogation, reimbursement,

Second Lien Credit Agreement

 

70

exoneration, contribution or indemnification rights of such Guarantor or other rights of such
Guarantor to proceed against any of the other Loan Parties, any other guarantor or any other Person
or any Collateral and (ii) any defense based on any right of set-off or counterclaim against or in
respect of the Obligations of such Guarantor hereunder.

          (d) Each Guarantor acknowledges that the Collateral Agent may, without notice to or demand
upon such Guarantor and without affecting the liability of such Guarantor under this Subsidiary
Guaranty, realize upon any security by nonjudicial sale, and each Guarantor hereby waives any
defense to the recovery by the Collateral Agent and the other Secured Parties against such
Guarantor of any deficiency after such nonjudicial sale and any defense or benefits that may be
afforded by applicable law.

          (e) Each Guarantor hereby unconditionally and irrevocably waives any duty on the part of any
Secured Party to disclose to such Guarantor any matter, fact or thing relating to the business,
condition (financial or otherwise), operations, performance, properties or prospects of any other
Loan Party or any of its Subsidiaries now or hereafter known by such Secured Party.

          (f) Each Guarantor acknowledges that it will receive substantial direct and indirect benefits
from the financing arrangements contemplated by the Loan Documents and that the waivers set forth
in Section 9.02 and this Section 9.03 are knowingly made in contemplation of such benefits.

     SECTION 9.04. Subrogation. Each Guarantor hereby unconditionally and irrevocably agrees
not to exercise any rights that it may now have or hereafter acquire against the Borrower, any
other Loan Party or any other insider guarantor that arise from the existence, payment, performance
or enforcement of such Guarantor’s Obligations under or in respect of this Subsidiary Guaranty or
any other Loan Document, including, without limitation, any right of subrogation, reimbursement,
exoneration, contribution or indemnification and any right to participate in any claim or remedy of
any Secured Party against the Borrower, any other Loan Party or any other insider guarantor or any
Collateral, whether or not such claim, remedy or right arises in equity or under contract, statute
or common law, including, without limitation, the right to take or receive
from the Borrower, any other Loan Party or any other insider guarantor, directly or indirectly, in
cash or other property or by set-off or in any other manner, payment or security on account of such
claim, remedy or right, unless and until all of the Guaranteed Obligations and all other amounts
payable under this Subsidiary Guaranty shall have been paid in full in cash and all Secured Hedge
Agreements shall have expired or been terminated. If any amount shall be paid to any Guarantor in
violation of the immediately preceding sentence at any time prior to the latest of (a) the payment
in full in cash of the Guaranteed Obligations and all other amounts payable under this Subsidiary
Guaranty, (b) the Maturity Date and (c) the latest date of expiration or termination of all Secured
Hedge Agreements, such amount shall be received and held in trust for the benefit of the Secured
Parties, shall be segregated from other property and funds of such Guarantor and shall forthwith be
paid or delivered to the Administrative Agent in the same form as so received (with any necessary
endorsement or assignment) to be credited and applied to the Guaranteed Obligations and all other
amounts payable under this Subsidiary Guaranty, whether matured or unmatured, in accordance with
the terms of the Loan Documents, or to be held as Collateral for any Guaranteed Obligations or
other amounts payable under this Subsidiary Guaranty thereafter arising. If (i) any Guarantor
shall make payment to any Secured Party of all or any part of the Guaranteed Obligations, (ii) all
of the Guaranteed Obligations and all other amounts payable under this Subsidiary Guaranty shall
have been paid in full in cash, (iii) the Maturity Date shall have occurred and (iv) all Secured
Hedge Agreements shall have expired or been terminated, the Secured Parties will, at such
Guarantor’s request and expense, execute and deliver to such Guarantor appropriate documents,
without recourse and without representation or warranty, necessary to evidence the transfer by
subrogation to such Guarantor of an interest in the Guaranteed Obligations resulting from such
payment made by such Guarantor pursuant to this Subsidiary Guaranty.

     SECTION 9.05. Guaranty Supplements. Upon the execution and delivery by any Person of a
guaranty supplement in substantially the form of Exhibit M hereto (each, a “Guaranty Supplement”),
(a) such Person shall be referred to as an “Additional Guarantor” and shall become and be a
Guarantor hereunder, and each reference in this Subsidiary Guaranty to a “Guarantor” shall also
mean and be a reference to such Additional Guarantor, and each reference in any other Loan Document
to a “Subsidiary Guarantor” shall also mean and be a reference to such Additional Guarantor, and
(b) each reference herein to “this Guaranty”, of this “Subsidiary Guaranty”, “hereunder”, “hereof”
or words of like import referring to this Subsidiary Guaranty, and each reference in any other Loan
Document to the “Guaranty”, “Subsidiary Guaranty” “thereunder”, “thereof” or words of like import
referring to this Guaranty, shall mean and be a reference to this Subsidiary Guaranty as
supplemented by such Guaranty Supplement.

     SECTION 9.06. Subordination. Each Guarantor hereby subordinates any and all debts,
liabilities and other Obligations owed to such Guarantor by each other Loan Party (the
“Subordinated Obligations”) to the Guaranteed Obligations to the extent and in the manner
hereinafter set forth in this Section 9.06:

          (a) Prohibited Payments, Etc. Except during the continuance of a Default, each
Guarantor may receive regularly scheduled payments or other payments then due from any other Loan
Party on account of the Subordinated Obligations. After the occurrence and during the continuance
of any Default, however, unless the Required Lenders otherwise agree, no Guarantor shall demand,
accept or take any action to collect any payment on account of the Subordinated Obligations.

          (b) Prior Payment of Guaranteed Obligations. In any proceeding under any Bankruptcy
Law relating to any other Loan Party, each Guarantor agrees that the Secured Parties shall be
entitled to receive payment in full in cash of all Guaranteed Obligations (including all interest
and expenses accruing
after the commencement of a proceeding under any Bankruptcy Law, whether or not constituting
an allowed claim in such proceeding (“Post-Petition Interest”)) before such Guarantor receives
payment of any Subordinated Obligations.

          (c) Turn-Over. After the occurrence and during the continuance of any Default, each
Guarantor shall, if the Administrative Agent so requests, collect, enforce and receive payments on
account of the Subordinated Obligations as trustee for the Secured Parties and deliver such
payments to the Administrative Agent on account of the Guaranteed Obligations (including all
Post-Petition Interest), together with any necessary endorsements or other instruments of transfer,
but without reducing or affecting in any manner the liability of such Guarantor under the other
provisions of this Subsidiary Guaranty.

          (d) Administrative Agent Authorization. After the occurrence and during the
continuance of any Default, the Administrative Agent is authorized and empowered (but without any
obligation to so do), in its discretion, (i) in the name of each Guarantor, to collect and enforce,
and to submit claims in respect of, the Subordinated Obligations and to apply any amounts received
thereon to the Guaranteed Obligations (including any and all Post-Petition Interest), and (ii) to
require each Guarantor (A) to collect and enforce, and to submit claims in respect of, the
Subordinated Obligations and (B) to pay any amounts received on such obligations to the
Administrative Agent for application to the Guaranteed Obligations (including any and all
Post-Petition Interest).

     SECTION 9.07. Continuing Guaranty; Assignments. This Subsidiary Guaranty is a continuing
guaranty and shall (a) remain in full force and effect until the latest of (i) the payment in full
in cash of the Guaranteed Obligations and all other amounts payable under this Subsidiary Guaranty,
(ii) the Maturity Date and (iii) the latest date of expiration or termination of all Secured Hedge
Agreements, (b) be binding

72

upon each Guarantor, its successors and assigns and (c) inure to the
benefit of and be enforceable by the Secured Parties and their successors, transferees and assigns.
Without limiting the generality of clause (c) of the immediately preceding sentence, any Secured
Party may assign or otherwise transfer all or any portion of its rights and obligations under this
Agreement (including, without limitation, all or any portion of its Commitments, the Advances owing
to it and any Note or Notes held by it) to any other Person, and such other Person shall thereupon
become vested with all the benefits in respect thereof granted to such Secured Party herein or
otherwise, in each case as and to the extent provided in Section 10.07. No Guarantor shall have
the right to assign its rights hereunder or any interest herein without the prior written consent
of the Secured Parties.

MISCELLANEOUS

     SECTION 10.01. Amendments, Etc. No amendment or waiver of any provision of this Agreement
or the Notes or any other Loan Document, nor consent to any departure by any Loan Party therefrom,
shall in any event be effective unless the same shall be in writing and signed (or, in the case of
the Collateral Documents, consented to) by the Required Lenders, and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose for which given;
provided, however, that (a) no amendment, waiver or consent shall, unless in writing and signed by
all of the Lenders, do any of the following at any time:

     (i) waive any of the conditions specified in Section 3.01,

     (ii) change the number of Lenders or the percentage of the aggregate unpaid principal
amount of the Advances that shall be required for the Lenders or any of them to take any
action hereunder,

     (iii) release one or more Guarantors (or otherwise limit such Guarantors’ liability

Guaranties) if such release or limitation is in respect of all or substantially all of the
value of the Subsidiary Guaranties to the Lenders,

     (iv) release all or substantially all of the Collateral in any transaction or series of
related transactions, or

     (v) amend this Section 10.01,

73

provided further that no amendment, waiver or consent shall, unless in writing and signed by an
Agent in addition to the Lenders required above to take such action, affect the rights or duties of
such Agent under this Agreement or the other Loan Documents.

          In the event that (1) the Borrower or the Administrative Agent has requested the Lenders to
consent to a departure or waiver of any provisions of the Loan Documents or to agree to any
amendment thereto, (2) the consent, waiver or amendment in question requires the agreement of all
Lenders or all affected Lenders in accordance with the terms of this Section 10.01 and (3) the
Required Lenders have agreed to such consent, waiver or amendment, then any Lender who does not
agree to such consent, waiver or amendment shall be deemed a “Non-Consenting Lender.” The Borrower

full to one or more Persons selected by the Borrower so long as (a) each such Person is reasonably
satisfactory to the Administrative Agent, (b) such Lender receives payment in full in cash of the
outstanding principal amount of all Advances made by it and all accrued and unpaid interest thereon
and all other amounts due and payable to such Lender as of the date of such assignment (including,
without limitation, amounts owing pursuant to Sections 2.08, 2.10 and 9.04 and an amount equal to
the premium that would be payable pursuant to Section 2.04 if such Non-Consenting Lender received a
prepayment of all of its outstanding Advances on the date of such assignment) and (c) each such
Person assignee agrees to accept such assignment and to assume all obligations of such Lender

Credit (including any election of an interest rate or interest period relating thereto), (ii)
relates to the payment of any principal or other amount due under this Agreement prior to the

Administrative Agent to an electronic mail address specified by the Administrative Agent to the
Borrower. In addition, the Borrower agrees to continue to provide the Communications to the
Administrative Agent in the manner specified in the Loan Documents but only to the extent requested
by the Administrative Agent. The Borrower further agrees that the Administrative Agent may make
the Communications available to the Lenders by posting the Communications on IntraLinks or a
substantially similar electronic transmission system (the “Platform”). The Borrower hereby agrees
that certain of the Lenders may be “public-side” Lenders (i.e., Lenders that do not wish to
receive material non-public information with respect to the Borrower or its securities) (each, a
“Public Lender”) and that it will use commercially reasonable efforts to identify that portion of
the Communications that may be distributed to the Public Lenders and that (w) all such
Communications shall be clearly and conspicuously marked “PUBLIC” which, at a minimum, shall mean
that the word “PUBLIC” shall appear prominently on the first page thereof; (x) by marking
Communications “PUBLIC,” the Borrower shall be deemed to have authorized the Administrative Agent
to treat such Communications as either publicly available
information or not material information (although it may be sensitive and proprietary) with
respect to the Borrower or its securities for purposes of United States Federal and state
securities laws; (y) all Communications marked “PUBLIC” are permitted to be made available through
a portion of the Platform designated “Public Investor;” and (z) the Administrative Agent shall be
entitled to treat any Communications that are not marked “PUBLIC” as being suitable only for
posting on a portion of the Platform not designated “Public Investor.”

          (c) THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE”. THE AGENT PARTIES (AS DEFINED BELOW)
DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS, OR THE ADEQUACY OF THE PLATFORM
AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS OR OMISSIONS IN THE COMMUNICATIONS. NO WARRANTY OF ANY
KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR
FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT PARTIES IN CONNECTION WITH THE
COMMUNICATIONS OR THE PLATFORM. IN NO EVENT SHALL THE ADMINISTRATIVE AGENT OR ANY OF ITS
AFFILIATES OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR
REPRESENTATIVES (COLLECTIVELY, “AGENT PARTIES”) HAVE ANY LIABILITY TO ANY BORROWER, ANY LENDER OR
ANY OTHER PERSON OR ENTITY FOR DAMAGES OF ANY KIND, INCLUDING, WITHOUT LIMITATION, DIRECT OR
INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT,
CONTRACT OR OTHERWISE) ARISING OUT OF A BORROWER’S OR THE ADMINISTRATIVE AGENT’S TRANSMISSION OF
COMMUNICATIONS THROUGH THE INTERNET, EXCEPT TO THE EXTENT THE LIABILITY OF ANY AGENT PARTY IS FOUND
IN A FINAL NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED PRIMARILY
FROM SUCH AGENT PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

          (d) The Administrative Agent agrees that the receipt of the Communications by the
Administrative Agent at its e-mail address set forth above shall constitute effective delivery of
the

Second Lien Credit Agreement

 

75

Communications to the Administrative Agent for purposes of the Loan Documents. Each Lender
agrees that notice to it (as provided in the next sentence) specifying that the Communications have
been posted to the Platform shall constitute effective delivery of the Communications to such
Lender for purposes of the Loan Documents. Each Lender agrees to notify the Administrative Agent
in writing (including by electronic communication) from time to time of such Lender’s e-mail
address to which the foregoing notice may be sent by electronic transmission and (ii) that the
foregoing notice may be sent to such e-mail address. Nothing herein shall prejudice the right of
the Administrative Agent or any Lender to give any notice or other communication pursuant to any
Loan Document in any other manner specified in such Loan Document.

     SECTION 10.03. No Waiver; Remedies. No failure on the part of any Lender or any Agent to
exercise, and no delay in exercising, any right hereunder or under any Note or any other Loan
Document shall operate as a waiver thereof; nor shall any single or partial exercise of any such
right preclude any other or further exercise thereof or the exercise of any other right. The
remedies herein provided are cumulative and not exclusive of any remedies provided by law.

     SECTION 10.04. Costs and Expenses. (a) The Borrower agrees to pay on demand within 15 days of demand written (i) all reasonable
and documented costs and expenses of each Agent in connection with the preparation, execution,
delivery, administration, modification and amendment of, or any consent or waiver under, the Loan
Documents (including, without limitation, (A) all due diligence, collateral review, syndication,
transportation, computer, duplication, appraisal, audit, insurance, consultant, search, filing and
recording fees and expenses and (B) the reasonable and documented fees and expenses of counsel for
each Agent with respect thereto, with respect to advising such Agent as to its rights and
responsibilities, or the perfection, protection or preservation of rights or interests, under the
Loan Documents, with respect to negotiations with any Loan Party or with other creditors of any
Loan Party or any of its Subsidiaries arising out of any Default or any events or circumstances
that may give rise to a Default and with respect to presenting claims in or otherwise participating
in or monitoring any bankruptcy, insolvency or other similar proceeding involving creditors’ rights
generally and any proceeding ancillary thereto) and (ii) all costs and expenses of each Agent and
each Lender in connection with the enforcement of the Loan Documents, whether in any action, suit
or litigation, or any bankruptcy, insolvency or other similar proceeding affecting creditors’
rights generally (including, without limitation, the reasonable fees and expenses of counsel for
the Administrative Agent and each Lender with respect thereto determined, in respect of actions in
a court in Canada, on a solicitor and his own client full indemnity basis).

          (b) The Borrower agrees to indemnify, defend and save and hold harmless each Agent, each
Lender and each of their Affiliates and their respective officers, directors, employees, agents and
advisors (each, an “Indemnified Party”) from and against, and shall pay on demand, any and all
claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees
and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified
Party, in each case arising out of or in connection with or by reason of (including, without
limitation, in connection with any investigation, litigation or proceeding or preparation of a
defense in connection therewith) (i) the Facility, the actual or proposed use of the proceeds of
the Advances, the Loan Documents or any of the transactions contemplated thereby, or (ii) the
actual or alleged presence of Hazardous Materials on any property of any Loan Party or any of its
Subsidiaries or any Environmental Claim relating in any way to any Loan Party or any of its
Subsidiaries, except to the extent such claim, damage, loss, liability or expense is found in a
final, non-appealable judgment by a court of competent jurisdiction to have resulted from such
Indemnified Party’s gross negligence or willful misconduct. In the case of an investigation,
litigation or other proceeding to which the indemnity in this Section 10.04(b) applies, such
indemnity shall be effective whether or not such investigation, litigation or proceeding is brought
by any Loan Party, its directors, shareholders or creditors, any Indemnified Party or any other
Person, whether or not any

Second Lien Credit Agreement

 

76

Indemnified Party is otherwise a party thereto and whether or not the
Transaction is consummated. The Borrower also agrees not to assert any claim against any Agent,
any Lender or any of their Affiliates, or any of their respective officers, directors, employees,
agents and advisors, on any theory of liability, for special, indirect, consequential or punitive
damages arising out of or otherwise relating to the Facility, the actual or proposed use of the
proceeds of the Advances, the Loan Documents or any of the transactions contemplated by the Loan
Documents.

          (c) If any payment of principal of, or Conversion of, any Eurodollar Rate Advance is made by
the Borrower to or for the account of a Lender other than on the last day of the Interest Period
for such Advance, as a result of a payment or Conversion pursuant to Section 2.04, 2.07(b)(i),
2.08(d) or 2.14(d), acceleration of the maturity of the Advances pursuant to Section 7.01 or for
any other reason, or if the Borrower fails to make any payment or prepayment of an Advance for
which a notice of prepayment has been given or that is otherwise required to be made, whether
pursuant to Section 2.03, 2.04 or 7.01 or otherwise, the Borrower shall, upon demand by such Lender
(with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the
account of such Lender any amounts required to compensate such Lender for any additional losses,
costs or expenses that it may reasonably incur as a result of such payment or Conversion or such
failure to pay or prepay, as the case
may be, including, without limitation, any loss (including loss of anticipated profits), cost
or expense incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by any Lender to fund or maintain such Advance.

          (d) If any Loan Party fails to pay when due any costs, expenses or other amounts payable by it
under any Loan Document, including, without limitation, fees and expenses of counsel and
indemnities, such amount may be paid on behalf of such Loan Party by the Administrative Agent or
any Lender, in its sole discretion.

          (e) Without prejudice to the survival of any other agreement of any Loan Party hereunder or
under any other Loan Document, the agreements and obligations of the Borrower contained in Sections
2.08 and 2.10 and this Section 10.04 shall survive the payment in full of principal, interest and
all other amounts payable hereunder and under any of the other Loan Documents.

     SECTION 10.05. Right of Set-off. Upon (a) the occurrence and during the continuance of any
Event of Default and (b) the making of the request or the granting of the consent specified by
Section 7.01 to authorize the Administrative Agent to declare the Advances due and payable pursuant
to the provisions of Section 7.01, each Agent and each Lender and each of their respective
Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted
by law, to set off and otherwise apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing by such Agent, such
Lender or such Affiliate to or for the credit or the account of the Borrower against any and all of
the Obligations of the Borrower now or hereafter existing under the Loan Documents, irrespective of
whether such Agent or such Lender shall have made any demand under this Agreement and although such
Obligations may be unmatured. Each Agent and each Lender agrees promptly to notify the Borrower
after any such set-off and application; provided, however, that the failure to give such notice
shall not affect the validity of such set-off and application. The rights of each Agent and each
Lender and their respective Affiliates under this Section are in addition to other rights and
remedies (including, without limitation, other rights of set-off) that such Agent, such Lender and
their respective Affiliates may have.

     SECTION 10.06. Binding Effect. This Agreement shall become effective when it shall have
been executed by the Borrower, each Guarantor and each Agent and the Administrative Agent shall
have been notified by each Existing Lender and each Term Lender that such Lender has executed it
and thereafter shall be binding upon and inure to the benefit of the Borrower, each Agent and each
Lender and

Second Lien Credit Agreement

 

77

their respective successors and assigns, except that the Borrower shall not have the
right to assign its rights hereunder or any interest herein without the prior written consent of
each Lender.

     SECTION 10.07. Assignments and Participations. (a) Whenever in this Agreement any of the
parties hereto is referred to, such reference shall be deemed to include the permitted successors
and assigns of such party; and all covenants, promises and agreements by or on behalf of the
Borrower, the Agents and the Lenders that are contained in this Agreement shall bind and inure to
the benefit of their respective successors and assigns.

          (b) Each Lender may, with the prior written consent of the Administrative Agent (not to be
unreasonably withheld or delayed), assign to one or more assignees all or a portion of its rights
and obligations under this Agreement (including, without limitation, all or a portion of its
Commitment or Commitments, the Advances owing to it and the Note or Notes, if any, held by it);
provided, however,
that (i) each such assignment shall be of a uniform, and not a varying, percentage of all
rights and obligations under and in respect of any or all of the Facilities, (ii) except in the
case of an assignment to a Person that, immediately prior to such assignment, was a Lender, an
Affiliate of any Lender or an Approved Fund of any Lender or an assignment of all of a Lender’s
rights and obligations under this Agreement, the aggregate amount of the Advances being assigned to
such assignee pursuant to such assignment (determined as of the date of the Assignment and
Acceptance with respect to such assignment) shall in no event be less than $1,000,000 (or such
lesser amount as shall be approved by the Administrative Agent, or, if less, the entire remaining
amount of such Lender’s outstanding Advances; provided that such minimum aggregate amount shall be
aggregated for two or more simultaneous assignments by or to two or more Approved Funds or
Affiliates), (iii) no such assignments shall be permitted until the Administrative Agent shall have
notified the Lenders that syndication of the Commitments hereunder has been completed, (iv) the
parties to each such assignment shall (A) electronically execute and deliver to the Administrative
Agent an Assignment and Acceptance via an electronic settlement system acceptable to the
Administrative Agent (which initially shall be ClearPar, LLC) or (B) if no such system shall then
be specified by the Administrative Agent, manually execute and deliver to the Administrative Agent,
for its acceptance and recording in the Register, an Assignment and Acceptance, together with a
processing and recordation fee of $3,500 and (v) the assignee, if it shall not be a Lender, shall
deliver to the Administrative Agent an Administrative Questionnaire and all applicable tax forms.

          (c) Upon such execution, delivery, acceptance and recording, from and after the effective date
specified in such Assignment and Acceptance, (i) the assignee thereunder shall be a party hereto
and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (ii) the
Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been
assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (other than its
rights under Sections 2.08, 2.09 and 10.04 to the extent any claim thereunder relates to an event
arising prior to such assignment) and be released from its obligations under this Agreement (and,
in the case of an Assignment and Acceptance covering all of the remaining portion of an assigning
Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party
hereto).

          (d) By executing and delivering an Assignment and Acceptance, each Lender assignor thereunder
and each assignee thereunder confirm to and agree with each other and the other parties thereto and
hereto as follows: (i) such Lender warrants that it is the legal and beneficial owner of the
interest being assigned thereby free and clear of any adverse claim and that its Commitment, and
the outstanding balance of its Advances, without giving effect to assignments thereof which have
not become effective, are as set forth in such Assignment and Acceptance, (ii) except as set forth
in (i) above, such Lender makes no representation or warranty and assumes no responsibility with
respect to any statements,

Second Lien Credit Agreement

 

78

warranties or representations made in or in connection with any Loan
Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value
of, or the perfection or priority of any lien or security interest created or purported to be
created under or in connection with, any Loan Document or any other instrument or document
furnished pursuant thereto, or the financial condition of any Loan Party or the performance or
observance by any Loan Party of any of its obligations under any Loan Document or any other
instrument or document furnished pursuant thereto; (iii) such assignee represents and warrants that
it is legally authorized to enter into such Assignment and Acceptance; (iv) such assignee confirms
that it has received a copy of this Agreement, together with copies of the most recent financial
statements referred to in Section 4.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such Assignment and
Acceptance; (iv) such assignee will, independently and without reliance upon any Agent, such
assigning Lender or any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or not taking action
under this Agreement; (v) such assignee appoints and authorizes each Agent to take such action as agent on its
behalf and to exercise such powers and discretion under the Loan Documents as are delegated to such
Agent by the terms hereof and thereof, together with such powers and discretion as are reasonably
incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their
terms all of the obligations that by the terms of this Agreement are required to be performed by it
as a Lender, as the case may be.

          (e) The Administrative Agent, acting for this purpose (but only for this purpose) as the agent
of the Borrower, shall maintain at its address referred to in Section 10.02 a copy of each
Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the
names and addresses of the Lenders and the Commitment of, and principal amount of the Advances
owing to, each Lender from time to time (the “Register”). The entries in the Register shall be
conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agents and
the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for
all purposes of this Agreement. The Register shall be available for inspection by the Borrower or
any Agent or any Lender at any reasonable time and from time to time upon reasonable prior notice.

          (f) Upon its receipt of, and consent to, an Assignment and Acceptance executed by an assigning
Lender and an assignee, an Administrative Questionnaire completed in respect of the assignee
(unless the assignee shall already be a Lender hereunder), the processing and recordation fee
referred to in paragraph (b) of this Section 10.07, any applicable tax forms and any Note or Notes
(if any) subject to such assignment, the Administrative Agent shall, if such Assignment and
Acceptance has been completed and is in substantially the form of Exhibit C hereto, (i) accept such
Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii)
give prompt notice thereof to the Borrower and each other Agent. In the case of any assignment by
a Lender, within five Business Days after its receipt of such notice, the Borrower, at its own
expense, shall execute and deliver to the Administrative Agent in exchange for the surrendered Note
or Notes (if any) a new Note to the order of such assignee in an amount equal to the Commitment
assumed by it pursuant to such Assignment and Acceptance and, if any assigning Lender that had a
Note or Notes prior to such assignment has retained a Commitment hereunder, a new Note to the order
of such assigning Lender in an amount equal to the Commitment retained by it hereunder. Such new
Note or Notes shall be dated the effective date of such Assignment and Acceptance and shall
otherwise be in substantially the form of Exhibit A hereto. No assignment shall be effective
unless it has been recorded in the Register as provided in this paragraph (f).

          (g) Each Lender may without the consent of the Borrower, the other Lenders or the
Administrative Agent sell participations to one or more Persons (other than a natural person or any
Loan Party or any of its Affiliates) in or to all or a portion of its rights and obligations under
this Agreement (including, without limitation, all or a portion of its Commitments, the Advances
owing to it and the Note or Notes (if any) held by it); provided, however, that (i) such Lender’s
obligations under this Agreement

Second Lien Credit Agreement

 

79

shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations, (iii) such Lender
shall remain the holder of any such Note for all purposes of this Agreement and (iv) the Borrower,
the Agents and the other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender’s rights and obligations under this Agreement. Any agreement or
instrument pursuant to which a Lender sells such a participation shall provide that such Lender
shall retain the sole right to enforce this Agreement and to approve any amendment, modification
or waiver of any provision of this Agreement; provided that such agreement or instrument may
provide that such Lender will not, without the consent of the participant, agree to any amendment,
modification or waiver that would reduce the principal of, or interest on, the Advances or any fees
or other amounts payable hereunder, in each case to the extent subject to such participation,
postpone any date fixed for any payment of principal of, or interest on, the Advances or any fees
or other amounts payable hereunder, in each case to the extent subject to such participation, or
release all or substantially all of the Collateral or the value of the Subsidiary Guaranties.
Subject to paragraph (h) of
this Section, the Borrower agrees that each participant shall be entitled to the benefits of
Sections 2.08 and 2.10 to the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each
participant shall also be entitled to the benefits of Section 10.05 as though it were a Lender,
provided such participant agrees to be subject to Section 2.11 as though it were a Lender.

          (h) A participant shall not be entitled to receive any greater payment under Sections 2.08 and
2.10 than the applicable Lender would have been entitled to receive with respect to the
participation sold to such participant, unless the sale of the participation to such participant is
made with the Borrower’s prior written consent. A participant that would be Foreign Lender if it
were a Lender shall not be entitled to the benefits of Section 2.10 unless the Borrower is notified
of the participation sold to such participant and such participant agrees, for the benefit of the
Borrower, to comply with Section 2.10(e) as though it were a Lender. For greater certainty, in no
event shall the Borrower be required to pay a greater amount in aggregate under Section 2.10 as a
result of the sale by a Lender of a participation to a participant than the Borrower was required
to pay to such Lender prior to such sale, except to the extent agreed to by the Borrower in
writing.

          (i) Any Lender may, in connection with any assignment or participation or proposed assignment
or participation pursuant to this Section 10.07, disclose to the assignee or participant or
proposed assignee or participant any information relating to the Borrower furnished to such Lender
by or on behalf of the Borrower; provided, however, that, prior to any such disclosure, the
assignee or participant or proposed assignee or participant shall agree to preserve the
confidentiality of any Confidential Information received by it from such Lender.

          (j) Notwithstanding any other provision set forth in this Agreement, any Lender may at any
time create a security interest in all or any portion of its rights under this Agreement
(including, without limitation, the Advances owing to it and the Note or Notes (if any) held by it)
in favor of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of
the Federal Reserve System; provided that no such pledge or assignment shall release such Lender
from any of its obligations hereunder or substitute any such pledge or assignee for such Lender as
a party hereto.

          (k) Notwithstanding anything to the contrary contained herein, any Lender that is a Fund may
create a security interest in all or any portion of the Advances owing to it and any Note or Notes
held by it to the trustee for holders of obligations owed, or securities issued, by such Fund as
security for such obligations or securities; provided that unless and until such trustee actually
becomes a Lender in compliance with the other provisions of this Section 10.07, (i) no such pledge
shall release the pledging Lender from any of its obligations under the Loan Documents and (ii)
such trustee shall not be entitled to

Second Lien Credit Agreement

 

80

exercise any of the rights of a Lender under the Loan
Documents even though such trustee may have acquired ownership rights with respect to the pledged
interest through foreclosure or otherwise.

          (l) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting
Lender”) may grant to a special purpose funding vehicle identified as such in writing from time to
time by the Granting Lender to the Administrative Agent and the Borrower (an “SPC”) the option to
provide all or any part of any Advance that such Granting Lender would otherwise be obligated to
make pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by
any SPC to fund any Advance and (ii) if an SPC elects not to exercise such option or otherwise
fails to make all or any part of such Advance, the Granting Lender shall be obligated to make such
Advance pursuant to the terms hereof. The making of an Advance by an SPC hereunder shall utilize
the Commitment of the Granting Lender to the same extent, and as if, such Advance were made by such
Granting Lender. Each party hereto hereby agrees that (i) no SPC shall be liable for any indemnity
or similar payment obligation under this Agreement for which a Lender would be liable, (ii) no SPC
shall be entitled to the benefits of
Sections 2.08 and 2.10 (or any other increased costs protection provision) and (iii) the
Granting Lender shall for all purposes, including, without limitation, the approval of any
amendment or waiver of any provision of any Loan Document, remain the Lender of record hereunder.
In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the
termination of this Agreement) that, prior to the date that is one year and one day after the
payment in full of all outstanding commercial paper or other senior Debt of any SPC, it will not
institute against, or join any other Person in instituting against, such SPC any bankruptcy,
reorganization, arrangement, insolvency, or liquidation proceeding under the laws of the United
States or any State thereof. Notwithstanding anything to the contrary contained in this Agreement,
any SPC may (i) with notice to, but without prior consent of, the Borrower and the Administrative
Agent and without paying any processing fee therefor, assign all or any portion of its interest in
any Advance to the Granting Lender and (ii) disclose on a confidential basis any non-public
information relating to its funding of Advances to any rating agency, commercial paper dealer or
provider of any surety or guarantee or credit or liquidity enhancement to such SPC. This
subsection (l) may not be amended without the prior written consent of each Granting Lender, all or
any part of whose Advances are being funded by the SPC at the time of such amendment.

          (m) The Borrower shall not assign or delegate any of its rights or duties hereunder without
the prior written consent of the Administrative Agent and each Lender, and any such attempted
assignment without such consent shall be null and void.

     SECTION 10.08. Execution in Counterparts. This Agreement may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original and all of which taken together shall constitute one and
the same agreement. Delivery by telecopier of an executed counterpart of a signature page to this
Agreement shall be effective as delivery of an original executed counterpart of this Agreement.

     SECTION 10.09. Confidentiality. Neither any Agent nor any Lender shall disclose any
Confidential Information to any Person without the consent of the Borrower, other than (a) to such
Agent’s or such Lender’s Affiliates and their officers, directors, employees, agents and advisors
and to actual or prospective assignees and participants, and then only on a confidential basis, (b)
as required by any law, rule or regulation or judicial process, (c) as requested or required by any
state, Federal or foreign authority or examiner (including the National Association of Insurance
Commissioners or any similar organization or quasi-regulatory authority) regulating such Lender,
(d) to any rating agency when required by it, provided that, prior to any such disclosure, such
rating agency shall undertake to preserve the confidentiality of any Confidential Information
relating to the Loan Parties received by it from such Lender, (e) in connection with any litigation
or proceeding to which such Agent or such Lender or any of its Affiliates may be a party or (f) in
connection with the exercise of any right or remedy under this

Second Lien Credit Agreement

 

81

Agreement or any other Loan
Document. In addition, neither any Agent or any Lender shall use any Confidential Information
other than in connection with the transactions contemplated hereby and by the other Loan Documents
including, without limitation, in connection with any proposed assignment or participation (subject
to the limitations in clause (a) above) or in connection with the exercise of any right or remedy
under this Agreement or any other Loan Document.

     SECTION 10.10. Release of Collateral. (a) Upon the sale, lease, transfer or other
disposition of any item of Collateral of any Loan Party (including, without limitation, as a result
of the sale, in accordance with the terms of the Loan
Documents, of the Loan Party that owns such Collateral) in accordance with the terms of the Loan
Documents, the Collateral Agent will, at the Borrower’s expense, execute and deliver to such Loan
Party such documents as such Loan Party may reasonably request to evidence the release of such item
of Collateral from the assignment and security interest granted under the Collateral Documents in
accordance with the terms of the Loan Documents.

          (b) The Collateral Agent will, at the Borrower’s expense, execute and deliver to such Loan
Party such documents as such Loan Party may reasonably request to release any Subsidiary Guarantor
from its obligations under the Subsidiary Guarantor is such Person ceases to be a Subsidiary as a
result of a transaction permitted hereunder.

          (c) The Lenders hereby authorize the Administrative Agent, upon the written request of the
Borrower, to subordinate the Security Interests created by the Collateral Documents with respect to
any property or assets subject to a Permitted Encumbrance described in subparagraph (p) of the
definition thereof or release such Security Interests from any property or assets subject to a
Permitted Encumbrance described in subparagraph (p) of the definition thereof; provided that,
notwithstanding the foregoing, no Security Interests created by the Collateral Documents shall be
subordinated or released by the Administrative Agent on, to or with respect to any P&NG Rights or
P&NG Leases.

     SECTION 10.11. Patriot Act Notice. Each Lender and each Agent (for itself and not on
behalf of any Lender) hereby notifies the Loan Parties that pursuant to any requirements it may
have under the Patriot Act, it may be required to obtain, verify and record information that
identifies each Loan Party, which information includes the name and address of such Loan Party and
other information that will allow such Lender or such Agent, as applicable, to identify such Loan
Party in accordance with the Patriot Act. The Borrower shall, and shall cause each of its
Subsidiaries to, provide to the extent commercially reasonable, such information and take such
actions as are reasonably requested by any Agents or any Lender in order to assist the Agents and
the Lenders in maintaining compliance with the Patriot Act.

     SECTION 10.12. Jurisdiction, Etc. (a) Each of the parties hereto hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New
York State court or Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or relating to this
Agreement or any of the other Loan Documents to which it is a party, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally
agrees that all claims in respect of any such action or proceeding may be heard and determined in
any such New York State court or, to the fullest extent permitted by law, in such Federal court.
Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other
manner provided by law. Nothing in this Agreement shall affect any right that any party may
otherwise have to bring any action or proceeding relating to this Agreement or any of the other
Loan Documents in the courts of any jurisdiction.

          (b) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent
it may legally and effectively do so, any objection that it may now or hereafter have to the laying

Second Lien Credit Agreement

 

82

of venue of any suit, action or proceeding arising out of or relating to this Agreement or any of
the other Loan Documents to which it is a party in any New York State or Federal court. Each of
the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense
of an inconvenient forum to the maintenance of such action or proceeding in any such court.

     SECTION 10.13. Governing Law. Article VI of this Agreement shall be governed by, and
construed in accordance with, the laws of the Province of Alberta and the remainder of this
Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the
State of New York.

	 	Dated:                      ___, ___

          FOR VALUE RECEIVED, the undersigned, Trident Exploration Corp., a Nova Scotia unlimited
liability company (the “Borrower”), HEREBY PROMISES TO PAY                                                              or its
registered assigns (the “Lender”) for the account of its Applicable Lending Office (as defined in
the Credit Agreement referred to below) on the Maturity Date the principal amount of the Advance
(as defined below) then outstanding and owing to the Lender by the Borrower pursuant to the Amended
and Restated Credit Agreement dated as of April 25, 2006 (as amended, amended and restated,
supplemented or otherwise modified from time to time, the “Credit Agreement”; terms defined
therein, unless otherwise defined herein, being used herein as therein defined) among the Borrower,
the Lender and certain other lenders party thereto, Credit Suisse, Toronto Branch, as Collateral
Agent and as Administrative Agent for the Lender and such other lenders in respect of the Facility.

          The Borrower promises to pay interest on the unpaid principal amount of the Advance from the
date of such Advance until such principal amount is paid in full, at such interest rates, and
payable at such times, as are specified in the Credit Agreement.

          Both principal and interest are payable in lawful money of the United States of America to
Credit Suisse, Toronto Branch, as Administrative Agent, at                                         ,                                         ,
in same day funds. The Advance owing to the Lender by the Borrower, and all payments made on
account of principal thereof, shall be recorded by the Lender and, prior to any transfer hereof,
endorsed on the grid attached hereto, which is part of this Promissory Note; provided, however,
that the failure of the Lender to make any such recordation or endorsement shall not prevent any
such payment of principal from being credited against the Obligations of the Borrower under this
Promissory Note.

          This Promissory Note is one of the Notes referred to in, and is entitled to the benefits
of, the Credit Agreement. The Credit Agreement, among other things, (i) provides for the making of
a single advance (the “Advance”) by the Lender to the Borrower in an amount (less any repayments
made prior to the date hereof) not to exceed the U.S. dollar amount first above mentioned, the
indebtedness of the Borrower resulting from such Advance being evidenced by this Promissory Note,
and (ii) contains provisions for acceleration of the maturity hereof upon the happening of certain
stated events and also for prepayments on account of principal hereof prior to the maturity hereof
upon the terms and conditions therein specified. The obligations of the Borrower under this
Promissory Note and the other Loan Documents, and the obligations of the other Loan Parties under
the Loan Documents, are secured by the Collateral as provided in the Loan Documents.

EXHIBIT E

FORM OF

SOLVENCY CERTIFICATE

TRIDENT EXPLORATION CORP.

          Trident Exploration Corp., a Nova Scotia unlimited liability company (the “Borrower”), hereby
certifies that                      (the “Officer”) is the Chief Financial Officer of the Borrower and
is duly authorized to execute this Solvency Certificate on behalf of the Borrower, which is being
delivered pursuant to Section 3.01(a)(vi) of the Amended and Restated Credit Agreement dated as of
April 25, 2006 (the “Credit Agreement”) among the Borrower, the Subsidiary Guarantors, the Lenders
and Credit Suisse, Toronto Branch, as Collateral Agent and Administrative Agent (in such capacity,
the “Administrative Agent”; together with the Lenders party to the Credit Agreement, the “Lender
Group”). Unless otherwise defined herein, terms defined in the Credit Agreement are used herein as
therein defined.

          The Borrower hereby certifies that the Officer is generally familiar with the properties,
prospects, businesses, assets, finances and operations of the Borrower and each of its subsidiaries
and has carefully reviewed the Credit Agreement and the other Loan Documents that the Officer has
deemed relevant to each Guarantor and the contents of this Solvency Certificate and, in connection
herewith, has reviewed such other documentation and information and has made such investigation and
inquiries as the Officer deems necessary and prudent therefor. The Borrower hereby further
certifies that the financial information and assumptions which underlie and form the basis for the
representations made in this Solvency Certificate were reasonable when made and were made in good
faith and continue to be reasonable as of the date hereof.

          The Borrower understands that the Lenders are relying on the truth and accuracy of this
Solvency Certificate in connection with the transactions contemplated by the Credit Agreement and
the other Loan Documents (referred to in the Credit Agreement).

          The Borrower hereby certifies that:

          1. The financial data and projections set forth in the materials delivered by or on behalf of
the Loan Parties in connection with Section 5.01(e) of the Credit Agreement (the “Financial
Statements”) were prepared in good faith on the basis of the assumptions stated therein, which
assumptions are fair in the light of the conditions existing on the date hereof (it being
understood that such data and projections represent a business plan and do not constitute a
forecast or projection and there is no assurance that such business plan can be fully attained).

          2. On the date hereof, before and after giving effect to the consummation of the Transaction
and any other transactions contemplated by the Credit Agreement and the other Loan Documents, the
fair value of the property of the Borrower and its Subsidiaries, on a Consolidated basis, is
greater than the total amount of liabilities (including, without limitation, contingent liabilities
but excluding any intercompany indebtedness existing as of the date hereof) of the Borrower and its
Subsidiaries, on a Consolidated basis.

          3. On the date hereof, before and after giving effect to the consummation of the Transaction
and any other transactions contemplated by the Credit Agreement and the other Loan Documents, the
present fair saleable value of the assets of the Borrower and its Subsidiaries, on a Consolidated
basis, is not less than the amount that will be required to pay the probable liabilities of the

Exhibit E - Form of Solvency Certificate

 

2

Borrower and its Subsidiaries on their debts, on a Consolidated basis, (excluding any intercompany
indebtedness existing as of the date hereof) as such debts become absolute and matured.

          4. On the date hereof, before and after giving effect to the consummation of the Transaction
and any other transactions contemplated by the Credit Agreement and other Loan Documents, the
Borrower and its Subsidiaries, taken as a whole, do not intend to, and do not believe that they
will, incur debts or liabilities (including, without limitation, contingent liabilities but
excluding any intercompany indebtedness existing as of the date hereof) beyond the ability of the
Borrower and its Subsidiaries, on a Consolidated basis, to pay such debts and liabilities as such
debts and liabilities mature.

          5. On the date hereof, before and after giving effect to the consummation of the Transaction
and any other transactions contemplated by the Credit Agreement and the other Loan Documents, the
Borrower and its Subsidiaries, on a Consolidated basis, are not engaged in business or a
transaction, or are not about to engage in business or a transaction, for which the property of the
Borrower and its Subsidiaries, on a Consolidated basis, would constitute an unreasonably small
capital.

          6. The Borrower and its Subsidiaries, in consummating any of the transactions contemplated by
the Credit Agreement and the other Loan Documents, do not intend to hinder, delay or defraud either
present or future creditors or any other person to which the Borrower or any of its Subsidiaries
are or will become, on or after the date hereof, indebted.

          7. Each of the Borrower and its Subsidiaries are not Persons who are bankrupt and are not
Persons who reside, carry on business or have property in Canada, whose liabilities to creditors
provable as claims under the Canadian Federal Bankruptcy and Insolvency Act amount to one thousand
dollars, and

     (a) who are for any reason unable to meet their obligations as they generally become due,

     (b) who have ceased paying their current obligations in the ordinary course of business as
they generally become due, or

     (c) the aggregate of whose property is not, at a fair valuation, sufficient, or, if disposed
of at a fairly conducted sale under legal process, would not be sufficient to enable payment of all
their obligations, due and accruing due.

          8. In reaching the conclusions set forth in this Solvency Certificate, the Borrower has
considered, among other things:

	 	(a)	 	the cash and other current assets of each of the Borrower and
its Subsidiaries;
	 
	 	(b)	 	the contribution rights that each Guarantor will have against
each of the other Guarantors and the subrogation rights that each Guarantor
(other than the Borrower) will have against the Borrower;
	 
	 	(c)	 	all unliquidated and contingent liabilities of the Borrower and
its Subsidiaries, including, without limitation, any claims arising out of
pending or threatened litigation against such Borrower and its Subsidiaries, or
any of its respective property and assets, and in so doing, the Borrower has,
in good faith, computed the maximum amount of such unliquidated and contingent
liabilities as the maximum amount that, in light of all the facts and
circumstances existing on the

Exhibit E - Form of Solvency Certificate

 

3

	 	 	 	date hereof, represents the amount that can
reasonably be expected to become an actual or matured liability;
	 
	 	(d)	 	all of the other obligations and liabilities of the Borrower
and its Subsidiaries, whether matured or unmatured, liquidated or unliquidated,
disputed or
undisputed, secured or unsecured, subordinated, absolute, fixed or
contingent, including, without limitation, any claims arising out of pending
or threatened litigation against the Borrower and its Subsidiaries or any of
