Re: Amendment to Employment Agreement

Dear Pat:

     This letter shall confirm our agreement to amend your employment agreement with Emmis
Operating Company dated September 4, 2006, (the “Agreement”), upon the terms and subject to the
conditions set forth in this letter (the “Amendment”). Any capitalized words or phrases used and
not defined in this Amendment shall have the meanings ascribed to them in the Agreement. This
shall confirm that the parties have agreed as follows:

1. Section 6.4 is hereby deleted in its entirety and replaced with the following:

     “Completion Bonus. On or about September 3, 2009, Executive shall receive Twenty
Thousand (20,000) Shares (the “Completion Shares”) and Two Hundred Thousand Dollars ($200,000) (the
“Completion Payment”); provided, that (i) this Agreement is in effect on September
3, 2009 and has not been terminated for any reason (other than a material breach of this Agreement
by Employer); and (ii) Executive has fully performed all of Executive’s duties and obligations
under this Agreement throughout the Term and is not in breach of any of the material terms and
conditions of this Agreement. The Completion Shares shall be freely transferable when delivered to
Executive subject to Employer’s securities trading policy and applicable federal and state law.
Employer shall have the right, in its sole and absolute discretion, to pay Executive the value of
the Completion Shares (in the same manner applied to other senior management level employees) in
cash in lieu of granting Executive the Completion Shares. Employer may pay all or a portion of the
Completion Payment in Shares in the same manner utilized for other senior management level
employees. The Completion Shares and the Completion Payment shall be subject to withholding for
applicable taxes and as otherwise required by law.”

2. The following sentence shall be added at the end of Section 11.4:

     “Notwithstanding the preceding provisions or any provision of Exhibit A, Employer
shall have the right to amend the Change in Control Agreement to the extent

 

 

that it reasonably deems such amendment necessary to comply with the requirements of Code Section
409A.”

3. Section 11.5(g) shall be deleted in its entirety and replaced with the following language:

     “(g) Grant or pay to Executive The Completion Shares and Completion Payment, in the manner
otherwise prescribed in Section 6.4 within two (2) weeks after the termination date (subject to
applicable tax withholding and deductions as required by law).”

4. In Section 14, “David O. Barrett, Esq.” is deleted and replaced in its entirety with “Ian D.
Arnold, Esq.”

5. Section 15.12 is hereby deleted in its entirety and replaced with the following:

     “16. Gross Up for Taxes Imposed Under Code Section 409A.

     16.1 Employer’s Gross-Up Obligation. This Agreement is intended to comply
with Code Section 409A, and it is intended that no amounts payable hereunder shall be
subject to tax under Section 409A. If, however, Executive pays taxes imposed pursuant to
Code Section 409A, Employer shall reimburse Executive to the extent provided in Section
16.2 or 16.3.

     16.2 Reimbursement by Agreement. If, before Executive’s tax return due date
for the year in which an amount is paid hereunder, (i) Employer reasonably determines that
part or all of the amounts payable pursuant to this Agreement during the year was subject
to taxes under Code Section 409A, or (ii) Executive reasonably determines that part or all
of such amounts was subject to taxes under Code Section 409A, and Employer agrees with
Executive’s determination (such agreement not to be unreasonably withheld, conditioned or
delayed), Employer shall reimburse Executive for any taxes under Code Section 409A with
respect to such payment and any additional federal, state, or local income or employment
taxes imposed on Executive due to the foregoing reimbursement, so that the after-tax
payment to Executive is equal to the after-tax amount that Executive would have received if
Code Section 409A had not applied. Employer shall pay the reimbursement required by the
preceding sentence only if Executive provides acceptable proof of payment within sixty (60)
days after having paid the taxes subject to reimbursement. If Executive provides
acceptable proof to Employer within such period, Employer shall pay the reimbursement
required by this Section 16.2 as soon as administratively feasible (and under no
circumstances more than one hundred twenty (120) days) after receiving such proof.

     16.3 Reimbursement following Audit. If Employer does not report any portion
of the amounts payable to Executive hereunder as subject to taxes under Code Section 409A,
and as a result of a later tax audit by the Internal Revenue Service, Executive is required
to pay taxes under Code Section 409A, Employer

2

 

shall reimburse Executive for any taxes under Code Section 409A with respect to such
payment, any interest and penalties imposed on Executive for the failure to make timely
payment of such taxes (with respect to any period before the end of the audit), and any
additional federal, state, or local income or employment taxes imposed on Executive due to
the foregoing reimbursement, so that the after-tax payment to Executive is equal to the
after-tax amount that Executive would have received if Code Section 409A had not applied.
Employer shall pay the reimbursement required by the preceding sentence only if Executive
provides acceptable proof of payment within sixty (60) days after having paid the taxes
subject to reimbursement. If Executive provides acceptable proof to Employer within such
period, Employer shall pay the reimbursement required by this Section 16.3 as soon
as administratively feasible (and under no circumstances more than one hundred twenty (120)
days) after receiving such proof.”

     All of the terms and conditions set forth in the Agreement shall remain unchanged and in full
force and effect unless specifically modified in this Amendment. This Amendment shall be
incorporated by reference into the Agreement and made a part thereof. In the event of any conflict
between any provision of this Amendment and any provision of the Agreement, this Amendment shall
govern and control.

     Please sign below where indicated to signify your acceptance of the terms and conditions set
forth in this Amendment. Should you have any questions about this Amendment, please let me know.
I look forward to much continued success together.

Sincerely,

/s/ Jeffrey H. Smulyan

calculated by dividing the appropriate component by the other component, carrying the result to one
place more than the number of places by which such ratio is expressed herein and rounding the
result up or down to the nearest number (with a rounding-up if there is no nearest number).

1.05 Exchange Rates; Currency Equivalents.

     (a) The Domestic Administrative Agent shall determine the Spot Rates as of each Revaluation
Date to be used for calculating U.S. Dollar Equivalent amounts of Outstanding Amounts denominated
in Alternative Currencies. The Canadian Administrative Agent shall determine the Spot Rates as of
each Revaluation Date to be used for calculating Canadian Dollar Equivalent amounts of Outstanding
Amounts denominated in Alternative Currencies. Such Spot Rates shall become effective as of such
Revaluation Date and shall be the Spot Rates employed in converting any amounts between the
applicable currencies until the next Revaluation Date to occur. Except for purposes of financial
statements delivered by Loan Parties hereunder or calculating financial covenants hereunder or
except as otherwise provided herein, the applicable amount of any currency for purposes of the Loan
Documents shall be such U.S. Dollar Equivalent amount as so determined by the Domestic
Administrative Agent.

     (b) Wherever in this Agreement in connection with a Borrowing, conversion, continuation or
prepayment of a Loan or a Letter of Credit, an amount, such as a required maximum, minimum or
multiple amount, is expressed in U.S. Dollars or Canadian Dollars, as applicable, but such
Borrowing, Loan or Letter of Credit is denominated in an Alternative Currency, such amount shall be
the Alternative Currency Equivalent, respectively, of such amount (rounded to the nearest 1,000
units of the applicable currency), as determined by the applicable Administrative Agent.

1.06 Times of Day.

     Unless otherwise specified, all references herein to times of day shall be references to
Eastern time (daylight savings or standard, as applicable).

31

 

1.07 Letter of Credit Amounts.

     Unless otherwise specified herein, the amount of a Letter of Credit at any time shall be
deemed to be the stated amount of such Letter of Credit in effect at such time; provided,
however, that with respect to any Letter of Credit that, by its terms or the terms of any
Issuer Document related thereto, provides for one or more automatic increases in the stated amount
thereof, the amount of such Letter of Credit shall be deemed to be the maximum stated amount of
such Letter of Credit after giving effect to all such increases, whether or not such maximum stated
amount is in effect at such time.

Borrowing of, conversion to or continuation of Eurodollar Rate Loans that are Domestic
Revolving Loans shall be in a principal amount of US$5,000,000 or a whole multiple of
US$1,000,000 in excess thereof. Except as provided in Sections 2.03(c) and
2.04(c) each Borrowing of, or conversion to, Base Rate Loans that are Domestic
Revolving Loans shall be in a principal amount of US$1,000,000 or a whole multiple of
US$500,000 in excess thereof.

     (ii) With respect to Canadian Revolving Loans, each Borrowing, each conversion of
Canadian Revolving Loans from one Type to the other, and each continuation of Eurodollar
Rate Loans shall be made upon the Canadian Borrower’s irrevocable notice to the Canadian
Administrative Agent, which may be given by telephone. Each such notice must be received by
the Canadian Administrative Agent not later than (A) 12:00 p.m. three Business Days prior to
the requested date of any Borrowing of, conversion to or continuation of Eurodollar Rate
Loans that are Canadian Revolving Loans denominated in Canadian Dollars or of any conversion
of Eurodollar Rate Loans to Base Rate Loans, (B) 12:00 p.m. four Business Days prior to the

promptly by delivery to the Canadian Administrative Agent of a written Loan Notice,
appropriately completed and signed by a Responsible Officer of the Canadian Borrower. Each
Borrowing of, conversion to or continuation of Eurodollar Rate Loans that are Canadian

CAN$500,000 in excess thereof. Except as provided in Sections 2.03(c) each
Borrowing of, or conversion to, Base Rate Loans that are Canadian Revolving Loans shall be
in a principal amount of CAN$1,000,000 or a whole multiple of CAN$500,000 in excess thereof.

     (b) Each Loan Notice (whether telephonic or written) shall specify (i) whether the applicable
Borrower is requesting a Domestic Revolving Borrowing, a Canadian Revolving Borrowing, a conversion
of the Revolving Loans from one Type to the other, or a continuation of Eurodollar Rate Loans,
(ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which
shall be a Business Day), (iii) the principal amount of Loans to be borrowed, converted or
continued, (iv) the Type of Loans to be borrowed or to which existing Loans are to be converted,
(v) the currency of the Loans to be borrowed and (vi) if applicable, the duration of the Interest
Period with respect thereto. If EMS fails to specify a currency in a Loan Notice requesting a
Domestic Revolving Borrowing, then the Domestic

33

 

Revolving Loans so requested shall be made in U.S. Dollars. If the Canadian Borrower fails to
specify a currency in a Loan Notice requesting a Canadian Revolving Borrowing, then the Canadian
Revolving Loans so requested shall be made in Canadian Dollars. If a Borrower fails to specify a
Type of Loan in a Loan Notice or if a Borrower fails to give a timely notice requesting a
conversion or continuation, then the applicable Loans shall be made as, or converted to, Base Rate
Loans; provided, however, that in the case of a failure to timely request a
continuation of Domestic Revolving Loans denominated in Euros, such Domestic Revolving Loans shall
be continued as Eurodollar Rate Loans in their original currency with an Interest Period of one
month. Any automatic conversion to Base Rate Loans shall be effective as of the last day of the
Interest Period then in effect with respect to the applicable Eurodollar Rate Loans. If a Borrower
requests a Borrowing of, conversion to, or continuation of Eurodollar Rate Loans in any such Loan
Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest
Period of one month. No Loan may be converted or continued as a Loan denominated in a different
currency, but instead must be prepaid in the original currency of such Loan and reborrowed in other
currency.

     (c) Following receipt of a Loan Notice, the Domestic Administrative Agent shall promptly
notify each applicable Lender of the amount of its Applicable Percentage of the applicable Loans,
and if no timely notice of a conversion or continuation is provided by EMS, the Domestic
Administrative Agent shall notify each applicable Lender of the details of any automatic conversion
to Base Rate Loans or continuation of Loans denominated in Euros, in each case as described in the
preceding subsection. Following receipt of a Loan Notice, the Canadian Administrative Agent shall
promptly notify each applicable Lender of the amount of its Applicable Percentage of the applicable
Loans, and if no timely notice of a conversion or continuation is provided by the Canadian
Borrower, the Canadian Administrative Agent shall notify each applicable Lender of the details of
any automatic conversion to Base Rate Loans, in each case as described in the preceding subsection.
In the case of any Domestic Revolving Borrowing, each Domestic Lender shall make the amount of its
Loan available to the Domestic Administrative Agent in immediately available funds at the Domestic
Administrative Agent’s Office not later than 1:00 p.m. on the Business Day specified in the
applicable Loan Notice. In the case of any Canadian Revolving Borrowing, each Canadian Lender
shall make the amount of its Loan available to the Canadian Administrative Agent in immediately
available funds at the Canadian Administrative Agent’s Office for the applicable currency not later
than 1:00 p.m. (Toronto time), on the Business Day specified in the applicable Loan Notice. Upon
satisfaction of the applicable conditions set forth in Section 5.02 (and, if such Borrowing
is the initial Credit Extension, Section 5.01), the applicable Administrative Agent shall
make all funds so received available to the applicable Borrower in like funds as received by the
applicable Administrative Agent either by (i) crediting the account of the applicable Borrower on
the books of Bank of America (including Bank of America, acting through its Canada branch, as
applicable) with the amount of such funds or (ii) wire transfer of such funds, in each case in
accordance with instructions provided to (and reasonably acceptable to) such Administrative Agent
by the applicable Borrower; provided, however, (1) that if, on the date of a
Borrowing of Domestic Revolving Loans, there are Domestic L/C Borrowings outstanding, then the
proceeds of such Domestic Revolving Borrowing, first, shall be applied to the payment in
full of any such Domestic L/C Borrowings, and second, shall be made available to EMS as
provided above and (2) that if, on the date of a Borrowing of Canadian Revolving Loans, there are
Canadian L/C Borrowings outstanding, then the proceeds of such Canadian Revolving Borrowing,
first, shall be applied to the payment in full of any such Canadian L/C Borrowings, and
second, shall be made available to the Canadian Borrower as provided above.

     (d) Except as otherwise provided herein, a Eurodollar Rate Loan may be continued or converted
only on the last day of an Interest Period for such Eurodollar Rate Loan. During the existence of
a Default or Event of Default, (i) no Loans may be converted to or continued as Eurodollar Rate
Loans (other than Eurodollar Rate Loans denominated in Euros), (ii) the Required Canadian Lenders
may demand any or all of the then outstanding Eurodollar Rate Loans denominated in U.S. Dollars be
prepaid, or redenominated into Canadian Dollars in the amount of the Canadian Dollar Equivalent
thereof, on the

34

 

last day of the then current Interest Period with respect thereto, and (iii) the Required
Domestic Lenders may demand any or all of the then outstanding Eurodollar Rate Loans denominated in
Euros be prepaid, or redenominated into U.S. Dollars in the amount of the U.S. Dollar Equivalent
thereof, on the last day of the then current Interest Period with respect thereto

     (e) The applicable Administrative Agent shall promptly notify the applicable Borrower and the
applicable Lenders of the interest rate applicable to any Interest Period for Eurodollar Rate Loans
upon determination of such interest rate. At any time that Base Rate Loans are outstanding, the
applicable Administrative Agent shall notify the applicable Borrower and the applicable Lenders of
any change in prime rate as determined by the applicable Administrative Agent used in determining
the Base Rate promptly following the public announcement of such change.

     (f) After giving effect to all Borrowings, all conversions of Loans from one Type to the
other, and all continuations of Loans as the same Type, there shall not be more than ten Interest
Periods in effect with respect to all Loans.

     (g) EMS or the Canadian Borrower may at any time and from time to time, upon prior written
notice by the applicable Borrower to the applicable Administrative Agent, increase either (A) the
Aggregate Domestic Revolving Commitments (but not the Domestic Letter of Credit Sublimit or the
Euro Currency Sublimit) or (B) the Aggregate Canadian Revolving Commitments, or both, by an
aggregate amount of up to FIFTY MILLION DOLLARS (US$50,000,000) with additional Domestic Revolving
Commitments or Canadian Revolving Commitments or both from any existing Lender or any other Person
selected by the applicable Borrower and reasonably acceptable to the applicable Administrative
Agent and the applicable L/C Issuer; provided that:

     (i) any such increase shall be in a minimum principal amount of US$5,000,000 and in
integral multiples of US$1,000,000 in excess thereof and the Borrowers collectively may make
a maximum of three (3) requests;

     (ii) no Default or Event of Default shall exist and be continuing at the time of any
such increase;

     (iii) no existing Lender shall be under any obligation to increase its Domestic
Revolving Commitment or Canadian Revolving Commitment, as applicable, and any such decision
whether to increase its Domestic Revolving Commitment or Canadian Revolving Commitment, as
applicable, shall be in such Lender’s sole and absolute discretion;

     (iv) (A) any new Lender shall join this Agreement by executing such joinder documents
required by the applicable Administrative Agent and/or (B) any existing Lender electing to
increase its Domestic Revolving Commitment or Canadian Revolving Commitment, as applicable,
shall have executed a commitment agreement satisfactory to the applicable Administrative
Agent; and

     (v) as a condition precedent to such increase, the applicable Borrower shall deliver to
the applicable Administrative Agent a certificate of each Canadian Loan Party or each
Domestic Loan Party, as applicable, dated as of the date of such increase signed by a
Responsible Officer of such Loan Party (A) certifying and attaching the resolutions adopted
by such Loan Party approving or consenting to such increase and (B) certifying that, before
and after giving effect to such increase, (1) the representations and warranties contained
in Article VI and the other Loan Documents are true and correct in all material
respects on and as of the date of such increase, except to the extent that such
representations and warranties specifically refer to an earlier date, in

35

 

which case they are true and correct in all material respects as of such earlier date,
and except that for purposes of this Section 2.02(g), the representations and
warranties contained in subsections (a) and (b) of Section 6.05 shall be deemed to
refer to the most recent statements furnished pursuant to clauses (a) and (b), respectively,
of Section 7.01, (2) EMS is in compliance with the financial covenants of
Section 8.11, and (3) no Default or Event of Default exists.

     The applicable Borrower shall prepay any Loans owing by it and outstanding on the date
of any such increase (and pay any additional amounts required pursuant to Section
3.05) to the extent necessary to keep the outstanding Loans ratable with any revised
Domestic Revolving Commitments or Canadian Revolving Commitments, as applicable, arising
from any nonratable increase in the Domestic Revolving Commitments or Canadian Revolving
Commitments, as applicable, under this Section.

unless the applicable L/C Issuer has entered into satisfactory arrangements with the
applicable Borrower or such Lender to eliminate such L/C Issuer’s risk with respect
to such Lender.

extension provisions (each, an “Auto-Extension Letter of Credit”);
provided that any such Auto-Extension Letter of Credit must permit the applicable
L/C Issuer to prevent any such extension at least once in each twelve-month period
(commencing with the date of issuance of such Letter of Credit) by giving prior notice to
the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in
each such twelve-month period to be agreed upon at the time such Letter of Credit is issued.
Unless otherwise directed by the applicable L/C Issuer, a Borrower shall not be required to
make a specific request to such L/C Issuer for any such extension. Once an Auto-Extension
Letter of Credit has been issued, the applicable Lenders shall be deemed to have authorized
(but may not require) the applicable L/C Issuer to permit the extension of such Letter of
Credit at any time to an expiry date not later than the Letter of Credit Expiration Date;
provided, however, that the applicable L/C Issuer shall not permit any such
extension if (A) such L/C Issuer has determined that it would not be permitted, or would
have no obligation, at such time to issue such Letter of Credit in its revised form (as
extended) under the terms hereof (by reason of the provisions of clause (ii) or (iii) of
Section 2.03(a) or otherwise), or (B) it has received notice (which may be by
telephone or in writing) on or before the day that is seven Business Days before the
Non-Extension Notice Date (1) from the applicable Administrative Agent that the Required
Domestic Lenders or the Required Canadian Lenders, as applicable, have elected not to permit
such extension or (2) from the Domestic Administrative Agent, the Canadian Administrative
Agent, any Lender or either Borrower that one or more of the applicable conditions specified
in Section 5.02 is not then satisfied, and in each such case directing such L/C
Issuer not to permit such extension.

     (iv) Promptly after its delivery of any Letter of Credit or any amendment to a Letter
of Credit to an advising bank with respect thereto or to the beneficiary thereof, the
applicable L/C Issuer will also deliver to the applicable Borrower and the applicable
Administrative Agent a true and complete copy of such Letter of Credit or amendment.

     (c) Drawings and Reimbursements; Funding of Participations.

(i) (A) Upon receipt from the beneficiary of any Domestic Letter of Credit of any
notice of a drawing under such Domestic Letter of Credit, the Domestic L/C Issuer
shall notify EMS and the Domestic Administrative Agent thereof, including, in the
case of a Domestic Letter of Credit denominated in an Alternative Currency, both the
Alternative Currency amount of such drawing and the U.S. Dollar Equivalent thereof.
In the case of a Domestic Letter denominated in an Alternative Currency, the EMS
shall reimburse the Domestic L/C Issuer in U.S. Dollars in the U.S. Dollar
Equivalent of the amount of the applicable drawing. Not later than 11:00 a.m. on
the date of any payment by the Domestic L/C Issuer under a Domestic Letter of Credit
(each such date, a “Domestic Honor Date”), EMS shall reimburse the Domestic
L/C Issuer through the Domestic Administrative Agent in U.S. Dollars in an amount
equal to the U.S. Dollar Equivalent of the amount of such drawing (expressed in U.S.
Dollars in the amount of the U.S. Dollar Equivalent thereof). If EMS fails to so
reimburse the Domestic L/C Issuer by such time, the Domestic L/C Issuer shall
promptly notify the Domestic Administrative Agent of the Domestic Honor Date and the
amount of the unreimbursed drawing shall become the unreimbursed amount (the
“Domestic Unreimbursed Amount”). The Domestic Administrative Agent shall
promptly notify each Domestic Lender of the Domestic Honor Date, the Domestic
Unreimbursed Amount, and the amount of such Domestic Lender’s Applicable Percentage
thereof. In such event, EMS shall be deemed to have requested a Domestic Revolving
Borrowing of Base Rate Loans to be disbursed on the Domestic Honor Date in an amount
equal to the Domestic Unreimbursed Amount, without regard to the minimum and
multiples specified in Section 2.02 for the principal

40

 

amount of Base Rate Loans, but subject to the conditions set forth in Section
5.02 (other than the delivery of a Loan Notice) and provided that, after giving
effect to such Domestic Revolving Borrowing, the Total Domestic Revolving
Outstandings shall not exceed the Aggregate Domestic Revolving Commitments. Any
notice given by the Domestic L/C Issuer or the Domestic Administrative Agent
pursuant to this Section 2.03(c)(i)(A) may be given by telephone if
immediately confirmed in writing; provided that the lack of such an
immediate confirmation shall not affect the conclusiveness or binding effect of such
notice.

     (B) Upon receipt from the beneficiary of any Canadian Letter of Credit of any
notice of a drawing under such Canadian Letter of Credit, the Canadian L/C Issuer
shall notify the Canadian Borrower and the Canadian Administrative Agent thereof,
including, in the case of a Letter of Credit denominated in an Alternative Currency,
both the Alternative Currency amount of such drawing and the Canadian Dollar
Equivalent thereof. In the case of a Canadian Letter of Credit denominated in an
Alternative Currency, the Canadian Borrower shall reimburse the Canadian L/C Issuer
in Canadian Dollars; provided, that, the Canadian Borrower may reimburse the
Canadian L/C Issuer in Alternative Currency if such reimbursement is received by the
Canadian L/C Issuer on the date the drawing is paid by the Canadian L/C Issuer. In
the case of any such reimbursement in Canadian Dollars of a drawing under a Canadian
Letter of Credit denominated in an Alternative Currency, the Canadian L/C Issuer
shall notify the Canadian Borrower of the Canadian Dollar Equivalent of the amount
of the drawing promptly following the determination thereof. Not later than 11:00
a.m. (Toronto time) on the date of any payment by the Canadian L/C Issuer under a
Canadian Letter of Credit to be reimbursed in Canadian Dollars, or 11:00 a.m. on the
date of any payment by the Canadian L/C Issuer under a Canadian Letter of Credit to
be reimbursed in an Alternative Currency (each such date, a “Canadian Honor
Date”), the Canadian Borrower shall reimburse the Canadian L/C Issuer through
the Canadian Administrative Agent in an amount equal to the amount of such drawing
and in the applicable currency. If the Canadian Borrower fails to so reimburse the
Canadian L/C Issuer by such time, the Canadian L/C Issuer shall promptly notify the
Canadian Administrative Agent of the Canadian Honor Date and the amount of the
unreimbursed drawing shall become the unreimbursed amount (expressed in Canadian
Dollars in the amount of the Canadian Dollar Equivalent thereof in the case of a
Canadian Letter of Credit denominated in an Alternative Currency) (the “Canadian
Unreimbursed Amount”). The Canadian Administrative Agent shall promptly notify
each Canadian Lender of the Canadian Honor Date, the Canadian Unreimbursed Amount,
and the amount of such Canadian Lender’s Applicable Percentage thereof. In such
event, the Canadian Borrower shall be deemed to have requested a Canadian Revolving
Borrowing of Base Rate Loans to be disbursed on the Canadian Honor Date in an amount
equal to the Canadian Unreimbursed Amount, without regard to the minimum and
multiples specified in Section 2.02 for the principal amount of Base Rate
Loans, but subject to the conditions set forth in Section 5.02 (other than
the delivery of a Loan Notice) and provided that, after giving effect to such
Canadian Revolving Borrowing, the Total Canadian Revolving Outstandings shall not
exceed the Aggregate Canadian Revolving Commitments. Any notice given by the
Canadian L/C Issuer or the Canadian Administrative Agent pursuant to this
Section 2.03(c)(i)(B) may be given by telephone if immediately confirmed in
writing; provided that the lack of such an immediate confirmation shall not
affect the conclusiveness or binding effect of such notice.

41

 

(ii) (A) Each Domestic Lender shall upon any notice pursuant to Section
2.03(c)(i)(A) make funds available to the Domestic Administrative Agent for the
account of the Domestic L/C Issuer, in U.S. Dollars, at the Domestic Administrative
Agent’s Office in an amount equal to its Applicable Percentage of the Domestic
Unreimbursed Amount not later than 1:00 p.m. on the Business Day specified in such
notice by the Domestic Administrative Agent, whereupon, subject to the provisions of
Section 2.03(c)(iii)(A), each Domestic Lender that so makes funds available
shall be deemed to have made a Base Rate Loan to EMS in such amount. The Domestic
Administrative Agent shall remit the funds so received to the Domestic L/C Issuer in
U.S. Dollars.

     (B) Each Canadian Lender shall upon any notice pursuant to Section
2.03(c)(i)(B) make funds available to the Canadian Administrative Agent for the
account of the Canadian L/C Issuer, in Canadian Dollars, at the Canadian
Administrative Agent’s Office in an amount equal to its Applicable Percentage of the
Canadian Unreimbursed Amount not later than 1:00 p.m. (Toronto time) on the Business
Day specified in such notice by the Canadian Administrative Agent, whereupon,
subject to the provisions of Section 2.03(c)(iii)(B), each Canadian Lender
that so makes funds available shall be deemed to have made a Base Rate Loan to the
Canadian Borrower in such amount. The Canadian Administrative Agent shall remit the
funds so received to the Canadian L/C Issuer in Canadian Dollars.

(iii) (A) With respect to any Domestic Unreimbursed Amount that is not fully
refinanced by a Domestic Revolving Borrowing of Base Rate Loans because the
conditions set forth in Section 5.02 cannot be satisfied or for any other
reason, EMS shall be deemed to have incurred from the Domestic L/C Issuer a Domestic
L/C Borrowing in the amount of the Domestic Unreimbursed Amount that is not so
refinanced, which Domestic L/C Borrowing shall be due and payable on demand
(together with interest) and shall bear interest at the Default Rate. In such
event, each Domestic Lender’s payment to the Domestic Administrative Agent for the
account of the Domestic L/C Issuer pursuant to Section 2.03(c)(ii)(A) shall
be deemed payment in respect of its participation in such Domestic L/C Borrowing and
shall constitute a Domestic L/C Advance from such Domestic Lender in satisfaction of
its participation obligation under this Section 2.03.

     (B) With respect to any Canadian Unreimbursed Amount that is not fully
refinanced by a Canadian Revolving Borrowing of Base Rate Loans because the
conditions set forth in Section 5.02 cannot be satisfied or for any other
reason, the Canadian Borrower shall be deemed to have incurred from the Canadian L/C
Issuer a Canadian L/C Borrowing in the amount of the Canadian Unreimbursed Amount
that is not so refinanced, which Canadian L/C Borrowing shall be due and payable on
demand (together with interest) and shall bear interest at the Default Rate. In
such event, each Canadian Lender’s payment to the Canadian Administrative Agent for
the account of the Canadian L/C Issuer pursuant to Section 2.03(c)(ii)(B)
shall be deemed payment in respect of its participation in such Canadian L/C
Borrowing and shall constitute a Canadian L/C Advance from such Canadian Lender in
satisfaction of its participation obligation under this Section 2.03.

     (iv) Until each Lender funds its Revolving Loan or L/C Advance, as applicable, pursuant
to this Section 2.03(c) to reimburse the applicable L/C Issuer for any amount drawn

42

 

under any Letter of Credit, interest in respect of such Lender’s Applicable Percentage of
such amount shall be solely for the account of the applicable L/C Issuer.

     (v) Each Lender’s obligation to make Revolving Loans or L/C Advances to reimburse the
applicable L/C Issuer for amounts drawn under Letters of Credit, as contemplated by this
Section 2.03(c), shall be absolute and unconditional and shall not be affected by
any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right
which such Lender may have against the applicable L/C Issuer, any Borrower, any Subsidiary
or any other Person for any reason whatsoever; (B) the occurrence or continuance of a
Default, or (C) any other occurrence, event or condition, whether or not similar to any of
the foregoing; provided, however, that each Lender’s obligation to make
Revolving Loans pursuant to this Section 2.03(c) is subject to the conditions set
forth in Section 5.02 (other than delivery by the applicable Borrower of a Loan
Notice). No such making of an L/C Advance shall relieve or otherwise impair the obligation
of the applicable Borrower to reimburse the applicable L/C Issuer for the amount of any
payment made by such L/C Issuer under any Letter of Credit, together with interest as
provided herein.

     (vi) If any Lender fails to make available to the applicable Administrative Agent for
the account of the applicable L/C Issuer any amount required to be paid by such Lender
pursuant to the foregoing provisions of this Section 2.03(c) by the time specified
in Section 2.03(c)(ii), the applicable L/C Issuer shall be entitled to recover from
such Lender (acting through the applicable Administrative Agent), on demand, such amount
with interest thereon for the period from the date such payment is required to the date on
which such payment is immediately available to such L/C Issuer at a rate per annum equal to
the applicable Overnight Rate from time to time in effect. If such Lender pays such amount
(with interest and fees as aforesaid), the amount so paid shall constitute such Lender’s
Revolving Loan included in the relevant Revolving Borrowing or L/C Advance in respect of the
relevant L/C Borrowing, as the case may be. A certificate of the applicable L/C Issuer
submitted to any Lender (through the applicable Administrative Agent) with respect to any
amounts owing under this clause (vi) shall be conclusive absent manifest error.

     (d) Repayment of Participations.

     (i) At any time after an L/C Issuer has made a payment under any Letter of Credit and
has received from any Lender such Lender’s L/C Advance in respect of such payment in
accordance with Section 2.03(c), if the applicable Administrative Agent receives for
the account of the applicable L/C Issuer any payment in respect of the related Unreimbursed
Amount or interest thereon (whether directly from the applicable Borrower or otherwise,
including proceeds of Cash Collateral applied thereto by the applicable Administrative
Agent), the applicable Administrative Agent will distribute to such Lender its Applicable
Percentage thereof in the same funds as those received by such Administrative Agent.

     (ii) If any payment received by an Administrative Agent for the account of an L/C
Issuer pursuant to Section 2.03(c)(i) is required to be returned under any of the
circumstances described in Section 11.05 (including pursuant to any settlement
entered into by the applicable L/C Issuer in its discretion), each Lender shall pay to the
applicable Administrative Agent for the account of the applicable L/C Issuer its Applicable
Percentage thereof on demand of the applicable Administrative Agent, plus interest thereon
from the date of such demand to the date such amount is returned by such Lender, at a rate
per annum equal to the applicable Overnight Rate from time to time in effect. The
obligations of the Lenders under this clause shall survive the payment in full of the
Obligations and the termination of this Agreement.

43

 

     (e) Obligations Absolute. The obligation of the applicable Borrower to reimburse the
applicable L/C Issuer for each drawing under each Letter of Credit and to repay each L/C Borrowing
shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the
terms of this Agreement under all circumstances, including the following:

     (i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or
any other Loan Document;

     (ii) the existence of any claim, counterclaim, setoff, defense or other right that any
Borrower or any Subsidiary may have at any time against any beneficiary or any transferee of
such Letter of Credit (or any Person for whom any such beneficiary or any such transferee
may be acting), the applicable L/C Issuer or any other Person, whether in connection with
this Agreement, the transactions contemplated hereby or by such Letter of Credit or any
agreement or instrument relating thereto, or any unrelated transaction;

     (iii) any draft, demand, certificate or other document presented under such Letter of
Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any
statement therein being untrue or inaccurate in any respect; or any loss or delay in the
transmission or otherwise of any document required in order to make a drawing under such
Letter of Credit;

     (iv) any payment by the applicable L/C Issuer under such Letter of Credit against
presentation of a draft or certificate that does not strictly comply with the terms of such
Letter of Credit; or any payment made by the applicable L/C Issuer under such Letter of
Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession,
assignee for the benefit of creditors, liquidator, receiver or other representative of or
successor to any beneficiary or any transferee of such Letter of Credit, including any
arising in connection with any proceeding under any Debtor Relief Law;

     (v) any adverse change in the relevant exchange rates or in the availability of the
relevant Alternative Currency to the applicable Borrower or in the relevant currency markets
generally; or

     (vi) any other circumstance or happening whatsoever, whether or not similar to any of
the foregoing, including any other circumstance that might otherwise constitute a defense
available to, or a discharge of, any Borrower or any Subsidiary.

     The applicable Borrower shall promptly examine a copy of each Letter of Credit and each
amendment thereto that is delivered to it and, in the event of any claim of noncompliance with the
applicable Borrower’s instructions or other irregularity, the applicable Borrower will promptly
notify the applicable L/C Issuer. The applicable Borrower shall be conclusively deemed to have
waived any such claim against the applicable L/C Issuer and its correspondents unless such notice
is given as aforesaid.

     (f) Role of the L/C Issuers. Each of the Lenders and the Borrowers agrees that, in
paying any drawing under a Letter of Credit, the applicable L/C Issuer shall not have any
responsibility to obtain any document (other than any sight draft, certificates and documents
expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or
accuracy of any such document or the authority of the Person executing or delivering any such
document. None of the L/C Issuers, the Administrative Agents, any of their respective Related
Parties nor any correspondent, participant or assignee of an L/C Issuer shall be liable to any
Lender for (i) any action taken or omitted in connection herewith at the request or with the
approval of the Required Domestic Lenders or the Required Canadian Lenders, as

44

 

applicable; (ii) any
action taken or omitted in the absence of gross negligence or willful misconduct; or
(iii) the due execution, effectiveness, validity or enforceability of any document or
instrument related to any Letter of Credit or Issuer Documents. Each Borrower hereby assumes all
risks of the acts or omissions of any beneficiary or transferee with respect to such Borrower’s use
of any Letter of Credit; provided, however, that this assumption is not intended to, and
shall not, preclude the applicable Borrower’s pursuing such rights and remedies as such Borrower
may have against the beneficiary or transferee at law or under any other agreement. None of the
L/C Issuers, the Administrative Agents, any of their respective Related Parties nor any
correspondent, participant or assignee of an L/C Issuer, shall be liable or responsible for any of
the matters described in clauses (i) through (v) of Section 2.03(e); provided,
however, that anything in such clauses to the contrary notwithstanding, a Borrower may have a claim
against the applicable L/C Issuer, and the applicable L/C Issuer may be liable to the applicable
Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or
exemplary, damages suffered by the applicable Borrower that such Borrower proves were caused by the
applicable L/C Issuer’s willful misconduct or gross negligence or such L/C Issuer’s willful failure
to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft
and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In
furtherance and not in limitation of the foregoing, the applicable L/C Issuer may accept documents
that appear on their face to be in order, without responsibility for further investigation,
regardless of any notice or information to the contrary, and the applicable L/C Issuer shall not be
responsible for the validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or
proceeds thereof, in whole or in part, that may prove to be invalid or ineffective for any reason.

     (g) Cash Collateral.

     (i) Upon the request of the applicable Administrative Agent, (A) if the applicable L/C
Issuer has honored any full or partial drawing request under any Letter of Credit and such
drawing has resulted in an L/C Borrowing, or (B) in addition to the requirement to provide
Cash Collateral in the following sentence, if, as of the Letter of Credit Expiration Date,
any L/C Obligation for any reason remains outstanding, the applicable Borrower shall, in
each case, immediately Cash Collateralize the then Outstanding Amount of its L/C
Obligations. Furthermore, if Letters of Credit have been issued pursuant to Section
2.03 with expiry dates beyond the Letter of Credit Expiration Date, then not later than
thirty (30) days prior to the Letter of Credit Expiration Date, the applicable Borrower
shall Cash Collateralize with the applicable Administrative Agent cash equal to 105% of the
Outstanding Amount of such Domestic Letters of Credit or Canadian Letters of Credit, as
applicable, as of such date plus any accrued and unpaid interest thereon.

     (ii) The Canadian Administrative Agent may, at any time and from time to time, request
that Cash Collateral be provided to the extent the Canadian Dollar Equivalent of all
outstanding Canadian Obligations exceeds the Canadian Revolving Commitments due to an
exchange rate fluctuation.

     (iii) EMS hereby grants to the Domestic Administrative Agent, for the benefit of the
Domestic L/C Issuer and the Domestic Lenders, a security interest in all such cash, deposit
accounts and all balances therein and all proceeds of the foregoing. Cash Collateral for
the Domestic L/C Obligations shall be maintained in blocked, interest bearing deposit
accounts at Bank of America. The Canadian Borrower hereby grants to the Canadian
Administrative Agent, for the benefit of the Canadian L/C Issuer and the Canadian Lenders, a
security interest in all such cash, deposit accounts and all balances therein and all
proceeds of the foregoing. Cash Collateral

45

 

for the Canadian L/C Obligations shall be
maintained in blocked, interest bearing deposit accounts at Bank of America, acting through
its Canada branch.

     (h) Applicability of ISP and UCP. Unless otherwise expressly agreed by the applicable
L/C Issuer and the applicable Borrower when a Letter of Credit is issued (including any such
agreement applicable to an Existing Domestic Letter of Credit or Existing Canadian Letter of
Credit), (i) the rules of the ISP shall apply to each standby Letter of Credit, and (ii) the rules
of the Uniform Customs and Practice for Documentary Credits, as most recently published by the
International Chamber of Commerce at the time of issuance, shall apply to each commercial Letter of
Credit.

     (i) Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of
Credit issued or outstanding hereunder is in support of any obligations of, or is for the account
of, any Subsidiary of a Borrower, the applicable Borrower shall be obligated to reimburse the
applicable L/C Issuer for any and all drawings under such Letter of Credit. The Borrowers hereby
acknowledge that the issuance of Letters of Credit for the account of either of any Subsidiary of
any Borrower inures to the benefit of such Borrower, and that such Borrower’s businesses derive
substantial benefits from the businesses of such Subsidiaries.

     (j) Letter of Credit Fees. EMS shall pay to the Domestic Administrative Agent for the
account of each Domestic Lender in accordance with its Applicable Percentage a Letter of Credit fee
(the “Domestic Letter of Credit Fee”) for each Domestic Letter of Credit equal to the
Applicable Rate times the U.S. Dollar Equivalent of the daily amount available to be drawn
under such Domestic Letter of Credit. The Canadian Borrower shall pay to the Canadian
Administrative Agent for the account of each Canadian Lender in accordance with its Applicable
Percentage a Letter of Credit fee for each Canadian Letter of Credit (the “Canadian Letter of
Credit Fee”) equal to the Applicable Rate times the Canadian Dollar Equivalent of the
daily amount available to be drawn under such Canadian Letter of Credit. For purposes of computing
the daily amount available to be drawn under any Letter of Credit, the amount of such Letter of
Credit shall be determined in accordance with Section 1.07. The Domestic Letter of Credit
Fee and the Canadian Letter of Credit Fee shall be (A) computed on a quarterly basis in arrears and
(B) due and payable on the last Business Day of each March, June, September and December,
commencing with the first such date to occur after the issuance of each such Letter of Credit, on
the Letter of Credit Expiration Date and thereafter on demand. If there is any change in the
Applicable Rate during any quarter, the daily amount available to be drawn under each Letter of
Credit shall be computed and multiplied by the Applicable Rate separately for each period during
such quarter that such Applicable Rate was in effect. Upon the request of the Required Domestic
Lenders, while any Event of Default exists, all Domestic Letter of Credit Fees shall accrue at the
Default Rate. Upon the request of the Required Canadian Lenders, while any Event of Default
exists, all Canadian Letter of Credit Fees shall accrue at the Default Rate.

     (k) Fronting Fee and Documentary and Processing Charges. EMS shall pay directly to
the Domestic L/C Issuer for its own account in U.S. Dollars a fronting fee (i) with respect to each
Domestic Letter of Credit, at the rate per annum specified in the Fee Letter, computed on the U.S.
Dollar Equivalent of the daily amount available to be drawn under such Domestic Letter of Credit
(whether or not such maximum amount is then in effect under such Domestic Letter of Credit) on a
quarterly basis in arrears and (ii) with respect to any amendment of a commercial Domestic Letter
of Credit increasing the amount of such Domestic Letter of Credit, at a rate separately agreed
between EMS and the Domestic L/C Issuer (such rate not to exceed the rate in the Fee Letter for
fronting fees), computed on the U.S. Dollar Equivalent of the amount of such increase, and payable
upon the effectiveness of such amendment. The Canadian Borrower shall pay directly to the Canadian
L/C Issuer for its own account a fronting fee (i) with respect to each Canadian Letter of Credit,
at the rate per annum specified in the Fee Letter, computed on the Canadian Dollar Equivalent of
the daily amount available to be drawn under such Canadian Letter of Credit (whether or not such
maximum amount is then in effect under such Canadian Letter of Credit) on a quarterly basis in
arrears and (ii) with respect to any amendment of a commercial Canadian Letter

46

 

of Credit increasing the amount of such Canadian Letter of Credit, at a rate separately agreed
between the Canadian Borrower and the Canadian L/C Issuer (such rate not to exceed the rate in the
Fee Letter for fronting fees), computed on the Canadian Dollar Equivalent of the amount of such
increase, and payable upon the effectiveness of such amendment. Such fronting fees shall be due
and payable on the last Business Day of each March, June, September and December in respect of each
quarter period (or portion thereof, in the case of the first payment), commencing with the first
such date to occur after the issuance of any such Letter of Credit, on the Letter of Credit
Expiration Date and thereafter on demand. For purposes of computing the daily amount available to
be drawn under any Domestic Letter of Credit, the amount of such Letter of Credit shall be
determined in accordance with Section 1.07. In addition, (i) EMS shall pay directly to the
Domestic L/C Issuer for its own account the customary issuance, presentation, amendment and other
processing fees, and other standard costs and charges, of the Domestic L/C Issuer relating to
letters of credit as from time to time in effect and (ii) the Canadian Borrower shall pay directly
to the Canadian L/C Issuer for its own account the customary issuance, presentation, amendment and
other processing fees, and other standard costs and charges, of the Canadian L/C Issuer relating to
letters of credit as from time to time in effect. Such customary fees and standard costs and
charges are due and payable on demand and are nonrefundable.

     (l) Conflict with Issuer Documents. In the event of any conflict between the terms
hereof and the terms of any Issuer Document, the terms hereof shall control.

2.04 Prepayments.

     (a) Voluntary Prepayment. The Loans may be prepaid, in whole or in part without
premium or penalty, upon notice from the applicable Borrower; provided that (A) such notice
must be received not later than 11:00 a.m. by the Domestic Administrative Agent, with respect to
any Domestic Revolving Loans, and not later than 11:00 a.m. (Toronto time) by the Canadian
Administrative Agent, with respect to Canadian Revolving Loans, (1) three Business Days prior to
any date of prepayment of Eurodollar Rate Loans denominated in U.S. Dollars or Canadian Dollars,
(2) on the date of prepayment of Base Rate Loans that are Domestic Revolving Loans and (3) (x) one

date of prepayment of Eurodollar Rate Loans that are Domestic Revolving Loans denominated in Euros;
(B) any such prepayment of Eurodollar Rate Loans shall be in a principal amount of (1) with respect
to Domestic Revolving Loans and Canadian Revolving Loans denominated in U.S. Dollars, US$1,000,000
or a whole multiple of US$500,000 in excess thereof (or, if less, the entire principal amount
thereof then outstanding) (2) with respect to Canadian Revolving Loans denominated in Canadian
Dollars, CAN $1,000,000 or a whole multiple of CAN $500,000 in excess thereof (or, if less, the
entire principal amount thereof then outstanding), and (3) with respect to Domestic Revolving Loans
denominated in Euros, US$1,000,000 or a whole multiple of US$500,000 in excess thereof; and (C) any
prepayment of Base Rate Loans shall be in a principal amount of (1) with respect to Domestic
Revolving Loans and Canadian Revolving Loans denominated in U.S. Dollars, US$500,000 or a whole
multiple of US$100,000 in excess thereof (or, if less, the entire principal amount thereof then
outstanding), and (2) with respect to Canadian Revolving Loans denominated in Canadian Dollars,
CAN$500,000 or a whole multiple of CAN$100,000 in excess thereof (or, if less, the entire principal
amount thereof then outstanding). Each such notice shall specify the date and amount of such
prepayment and the Type(s) of Loans to be prepaid and, if Eurodollar Rate Loans are to be prepaid,
the Interest Period(s) of such Loans. The applicable Administrative Agent will promptly notify
each Lender of its receipt of each such notice, and of the amount of such Lender’s Applicable
Percentage of such prepayment. If such notice is given by a Borrower, such Borrower shall make
such prepayment and the

47

 

payment amount specified in such notice shall be due and payable on the
date specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied by all
accrued interest on the amount
prepaid, together with any additional amounts required pursuant to Section 3.05. Each
such prepayment shall be applied to the Loans of the Lenders in accordance with their respective
Applicable Percentages.

     (b) Mandatory Prepayments of Loans.

     (i) Revolving Commitments.

     (A) Domestic Revolving Commitments. (1) If for any reason the Total
Domestic Revolving Outstandings at any time exceed the Aggregate Domestic Revolving
Commitments then in effect, EMS shall immediately prepay the Domestic Revolving
Loans and/or Cash Collateralize the Domestic L/C Obligations in an aggregate amount
equal to such excess.

     (2) Euro Currency Sublimit. If the Domestic Administrative Agent
notifies EMS at any time that the Outstanding Amount of all Domestic Revolving Loans
denominated in Euros exceeds the Euro Currency Sublimit then in effect, then, within
two Business Days after receipt of such notice, EMS shall prepay Domestic Revolving
Loans in an aggregate amount sufficient to reduce such Outstanding Amount as of such
date of payment to an amount not to exceed the Euro Currency Sublimit then in
effect.

     (B) Canadian Revolving Commitments. If for any reason the Total
Canadian Revolving Outstandings at any time exceed the Aggregate Canadian Revolving
Commitments then in effect, the Canadian Borrower shall immediately prepay the
Canadian Revolving Loans and/or Cash Collateralize the Canadian L/C Obligations in
an aggregate amount equal to such excess.

     (ii) Application of Mandatory Prepayments. All amounts required to be paid
pursuant to this Section 2.04(b) shall be applied as follows:

     (A) (1) with respect to all amounts prepaid pursuant to Section
2.04(b)(i)(A)(1), to Domestic Revolving Loans and (after all Domestic Revolving
Loans have been repaid) to Cash Collateralize the Domestic L/C Obligations; and

          (2) with respect to all amounts prepaid pursuant to Section
2.04(b)(i)(B), to Canadian Revolving Loans and (after all Canadian Revolving
Loans have been repaid) to Cash Collateralize the Canadian L/C Obligations.

Within the parameters of the applications set forth above, prepayments shall be
applied first to Base Rate Loans and then to Eurodollar Rate Loans in direct order
of Interest Period maturities. All prepayments under this Section 2.04(b)
shall be subject to Section 3.05, but otherwise without premium or penalty,
and shall be accompanied by interest on the principal amount prepaid through the
date of prepayment.

2.05 Termination or Reduction of Commitments.

     (a) Domestic Revolving Commitments. EMS may, upon notice to the Domestic
Administrative Agent, terminate the Aggregate Domestic Revolving Commitments, or from time to time
permanently reduce the Aggregate Domestic Revolving Commitments; provided that (i) any such
notice shall be received by the Domestic Administrative Agent not later than 11:00 a.m. five
Business Days

48

 

prior to the date of termination or reduction, (ii) any such partial reduction shall
be in an aggregate amount of US$1,000,000 or any whole multiple of US$500,000 in excess thereof,
(iii) EMS shall not
terminate or reduce the Aggregate Domestic Revolving Commitments if, after giving effect
thereto and to any concurrent prepayments hereunder, the Total Domestic Revolving Outstandings
would exceed the Aggregate Domestic Revolving Commitments as so reduced, and (iv) if, after giving
effect to any reduction of the Aggregate Domestic Revolving Commitments, the Domestic Letter of
Credit Sublimit or the Euro Currency Sublimit exceeds the amount of the Aggregate Domestic
Revolving Commitments, such sublimit shall be automatically reduced by the amount of such excess.
The Domestic Administrative Agent will promptly notify the applicable Lenders of any such notice of
termination or reduction of the Aggregate Domestic Revolving Commitments. The amount of any such
Aggregate Domestic Revolving Commitment reduction shall not be applied to the Domestic Letter of
Credit Sublimit or the Euro Currency Sublimit unless otherwise specified by EMS. Any reduction of
the Aggregate Domestic Revolving Commitments shall be applied to the Domestic Revolving Commitment
of each Domestic Lender according to its Applicable Percentage. All fees accrued until the
effective date of any termination of the Aggregate Domestic Revolving Commitments shall be paid on
the effective date of such termination.

     (b) Canadian Revolving Commitments. The Canadian Borrower may, upon notice to the
Canadian Administrative Agent, terminate the Aggregate Canadian Revolving Commitments, or from time
to time permanently reduce the Aggregate Canadian Revolving Commitments; provided that (i)
any such notice shall be received by the Canadian Administrative Agent not later than 11:00 a.m.
(Toronto time) five Business Days prior to the date of termination or reduction, (ii) any such
partial reduction shall be in an aggregate amount of CAN$1,000,000 or any whole multiple of
CAN$500,000 in excess thereof, and (iii) the Canadian Borrower shall not terminate or reduce the
Aggregate Canadian Revolving Commitments if, after giving effect thereto and to any concurrent
prepayments hereunder, the Total Canadian Revolving Outstandings would exceed the Aggregate
Canadian Revolving Commitments, as so reduced. The Canadian Administrative Agent will promptly
notify the applicable Lenders of any such notice of termination or reduction of the Aggregate
Canadian Revolving Commitments. Any reduction of the Aggregate Canadian Revolving Commitments
shall be applied to the Canadian Revolving Commitment of each Canadian Lender according to its
Applicable Percentage. All fees accrued until the effective date of any termination of the
Aggregate Canadian Revolving Commitments shall be paid on the effective date of such termination.

2.06 Repayment of Loans.

     (a) EMS shall repay to the Domestic Lenders on the Maturity Date the aggregate
principal amount of all Domestic Revolving Loans outstanding on such date.

     (b) The Canadian Borrower shall repay to the Canadian Lenders on the Maturity Date the
aggregate principal amount of all Canadian Revolving Loans outstanding on such date.

2.07 Interest.

     (a) Subject to the provisions of subsection (b) below, (i) each Eurodollar Rate Loan shall
bear interest on the outstanding principal amount thereof for each Interest Period at a rate per
annum equal to the sum of the Eurodollar Rate for such Interest Period plus the Applicable
Rate; and (ii) each Base Rate Loan shall bear interest on the outstanding principal amount thereof
from the applicable borrowing date at a rate per annum equal to the Base Rate plus the
Applicable Rate.

49

 

     (b) (i) If any amount of principal of any Loan is not paid when due (without regard to any
applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount
shall
thereafter bear interest at a fluctuating interest rate per annum at all times equal to the
Default Rate to the fullest extent permitted by applicable Laws.

     (ii) If any amount (other than principal of any Loan) payable by any Borrower under any
Loan Document is not paid when due (without regard to any applicable grace periods), whether
at stated maturity, by acceleration or otherwise, such amount shall thereafter bear interest
at a fluctuating interest rate per annum at all times equal to the Default Rate to the
fullest extent permitted by applicable Laws.

     (iii) Upon the request of the Required Domestic Lenders, while any Default or Event of
Default exists, EMS shall pay interest on the principal amount of all outstanding
Obligations (other than Canadian Obligations) hereunder at a fluctuating interest rate per
annum at all times equal to the Default Rate to the fullest extent permitted by applicable
Laws. Upon the request of the Required Canadian Lenders, while any Default or Event of
Default exists, the Canadian Borrower shall pay interest on the principal amount of all
outstanding Canadian Obligations hereunder at a fluctuating interest rate per annum at all
times equal to the Default Rate to the fullest extent permitted by applicable Laws.

     (iv) Accrued and unpaid interest on past due amounts (including interest on past due
interest) shall be due and payable upon demand.

     (c) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date
applicable thereto and at such other times as may be specified herein. Interest hereunder shall be
due and payable in accordance with the terms hereof before and after judgment, and before and after
the commencement of any proceeding under any Debtor Relief Law.

2.08 Fees.

     In addition to certain fees described in subsections (j) and (k) of Section 2.03:

     (a) (i) Domestic Commitment Fee. EMS shall pay to the Domestic Administrative
Agent for the account of each Domestic Lender in accordance with its Applicable Percentage,
a commitment fee (the “Domestic Commitment Fee”) equal to the product of (i) the
Applicable Rate times (ii) the actual daily amount by which the Aggregate Domestic
Revolving Commitments exceed the sum of (y) the Outstanding Amount of Domestic Revolving
Loans and (z) the Outstanding Amount of Domestic L/C Obligations. The Domestic Commitment
Fee shall accrue at all times during the Domestic Availability Period, including at any time
during which one or more of the conditions in Article V is not met, and shall be due
and payable quarterly in arrears on the last Business Day of each March, June, September and
December, commencing with the first such date to occur after the Closing Date, and on the
last day of the Domestic Availability Period. The Domestic Commitment Fee shall be
calculated quarterly in arrears, and if there is any change in the Applicable Rate during
any quarter, the actual daily amount shall be computed and multiplied by the Applicable Rate
separately for each period during such quarter that such Applicable Rate was in effect.

     (ii) Canadian Commitment Fee. The Canadian Borrower shall pay to the Canadian
Administrative Agent for the account of each Canadian Lender in accordance with its
Applicable Percentage, a commitment fee (the “Canadian Commitment Fee”) equal to the
product of (i) the Applicable Rate times (ii) the actual daily amount by which the
Aggregate Canadian Revolving

50

 

Commitments exceed the sum of (y) the Outstanding Amount of
Canadian Revolving Loans and (z) the Outstanding Amount of Canadian L/C Obligations. The
Canadian Commitment Fee shall
accrue at all times during the Canadian Availability Period, including at any time
during which one or more of the conditions in Article V is not met, and shall be due
and payable quarterly in arrears on the last Business Day of each March, June, September and
December, commencing with the first such date to occur after the Closing Date, and on the
last day of the Canadian Availability Period. The Canadian Commitment Fee shall be
calculated quarterly in arrears, and if there is any change in the Applicable Rate during
any quarter, the actual daily amount shall be computed and multiplied by the Applicable Rate
separately for each period during such quarter that such Applicable Rate was in effect.

     (b) Fee Letter. EMS shall pay to the Domestic Administrative Agent and the Canadian
Administrative Agent for their own respective accounts fees in the amounts and at the times
specified in the Fee Letter. Such fees shall be fully earned when paid and shall not be refundable
for any reason whatsoever.

2.09 Computation of Interest and Fees.

     (a) All computations of interest for Base Rate Loans when the Base Rate is determined by Bank
of America’s “prime rate” as determined by the applicable Administrative Agent shall be made on the
basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other
computations of fees and interest shall be made on the basis of a 360-day year and actual days
elapsed (which results in more fees or interest, as applicable, being paid than if computed on the
basis of a 365-day year). Interest shall accrue on each Loan for the day on which the Loan is
made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such
portion is paid, provided that any Loan that is repaid on the same day on which it is made
shall, subject to Section 2.11(a), bear interest for one day. Each determination by the
applicable Administrative Agent of an interest rate or fee hereunder shall be conclusive and
binding for all purposes, absent manifest error.

     (b) For the purposes of the Interest Act (Canada), (i) whenever a rate of interest or fee rate
hereunder is calculated on the basis of a year (the “deemed year”) that contains fewer days than
the actual number of days in the calendar year of calculation, such rate of interest or fee rate
shall be expressed as a yearly rate by multiplying such rate of interest or fee rate by the actual
number of days in the calendar year of calculation and dividing it by the number of days in the
deemed year, (ii) the principle of deemed reinvestment of interest shall not apply to any interest
calculation hereunder and (iii) the rates of interest stipulated herein are intended to be nominal
rates and not effective rates or yields.

     (c) If, as a result of any restatement of or other adjustment to the financial statements of
EMS or for any other reason, EMS or the Lenders determine that (i) the Consolidated Leverage Ratio
as calculated by EMS as of any applicable date was inaccurate and (ii) a proper calculation of the
Consolidated Leverage Ratio would have resulted in higher pricing for such period, EMS shall
immediately and retroactively be obligated to pay to the applicable Administrative Agent for the
account of the applicable Lenders or the applicable L/C Issuer, as the case may be, promptly on
demand by the applicable Administrative Agent (or, after the occurrence of an actual or deemed
entry of an order for relief with respect to EMS under the Debtor Relief Laws, automatically and
without further action by the applicable Administrative Agent, any Lender or the applicable L/C
Issuer), an amount equal to the excess of the amount of interest and fees that should have been
paid for such period over the amount of interest and fees actually paid for such period. This
paragraph shall not limit the rights of the Administrative Agents, any Lender or the L/C Issuers,
as the case may be, under Section 2.03(c)(iii), 2.03(i) or 2.07(b) or under
Article IX. EMS’s obligations under this paragraph shall survive the termination of the
Aggregate Commitments and the repayment of all other Obligations hereunder.

51

 

2.10 Evidence of Debt.

     (a) The Credit Extensions made by each Lender shall be evidenced by one or more accounts or
records maintained by such Lender and by the applicable Administrative Agent in the ordinary course
of business. The accounts or records maintained by the applicable Administrative Agent and each
Lender shall be conclusive absent manifest error of the amount of the Credit Extensions made by the
Lenders to the Borrowers and the interest and payments thereon. Any failure to so record or any
error in doing so shall not, however, limit or otherwise affect the obligation of the applicable
Borrower hereunder to pay any amount owing with respect to the Obligations. In the event of any
conflict between the accounts and records maintained by any Lender and the accounts and records of
the applicable Administrative Agent in respect of such matters, the accounts and records of the
applicable Administrative Agent shall control in the absence of manifest error. Upon the request
of any Lender made through the applicable Administrative Agent, the applicable Borrower shall
execute and deliver to such Lender (through the applicable Administrative Agent) a Note, which
shall evidence such Lender’s Loans in addition to such accounts or records. Each such Note shall
(i) in the case of Domestic Revolving Loans, be in the form of Exhibit 2.10(a)(i) (a
“Domestic Revolving Note”) and (ii) in the case of Canadian Revolving Loans, be in the form
of Exhibit 2.10(a)(ii) (a “Canadian Revolving Note”). Each Lender may attach
schedules to its Note and endorse thereon the date, Type (if applicable), amount and maturity of
its Loans and payments with respect thereto.

     (b) In addition to the accounts and records referred to in subsection (a), each Lender and the
applicable Administrative Agent shall maintain in accordance with its usual practice accounts or
records evidencing the purchases and sales by such Lender of participations in applicable Letters
of Credit. In the event of any conflict between the accounts and records maintained by the
applicable Administrative Agent and the accounts and records of any Lender in respect of such
matters, the accounts and records of the applicable Administrative Agent shall control in the
absence of manifest error.

2.11 Payments Generally; Administrative Agent’s Clawback.

     (a) General. All payments to be made by the Borrowers shall be made without condition
or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly
provided herein, (i) all payments by EMS hereunder with respect to principal and interest on
Domestic Revolving Loans (A) denominated in U.S. Dollars shall be made to the Domestic
Administrative Agent, for the account of the respective Lenders to which such payment is owed, at
the Domestic Administrative Agent’s Office in U.S. Dollars and in immediately available funds not
later than 2:00 p.m. on the date specified herein and (B) denominated in Euros shall be made to the
Domestic Administrative Agent, for the account of the respective Lenders to which such payment is
owed, at the Domestic Administrative Agent’s Office in Euros and in immediately available funds not
later than 2:00 p.m. on the date specified herein, and (ii) all payments by the Canadian Borrower
hereunder with respect to principal and interest on Canadian Revolving Loans (A) denominated in
Canadian Dollars shall be made to the Canadian Administrative Agent, for the account of the
respective Lenders to which such payment is owed, at the Canadian Administrative Agent’s Office in
Canadian Dollars and in immediately available funds not later than 2:00 p.m. (Toronto time) on the
dates specified herein, and (B) denominated in U.S. Dollars shall be made to the Canadian
Administrative Agent at the Canadian Administrative Agent’s Office in U.S. Dollars and in
immediately available finds not later than 2:00 p.m. on the date specified herein. Without
limiting the generality of the foregoing, (i) the Domestic Administrative Agent may require that
any payments due under this Agreement be made in the United States and (ii) the Canadian
Administrative Agent may require that any payments due from the Canadian Borrower under this
Agreement be made in Canada. If, for any reason, (a) EMS is prohibited by any Law from making any
required payment hereunder in Euros, EMS shall make such payment in U.S. Dollars in the U.S. Dollar
Equivalent of Euros

52

 

and/or (b) the Canadian Borrower is prohibited from making any required payment hereunder in
U.S. Dollars, the Canadian Borrower shall make such payment in Canadian Dollars in the Canadian
Dollar Equivalent of U.S. Dollars. The applicable Administrative Agent will promptly distribute to
each Lender its Applicable Percentage of such payment in like funds as received by wire transfer to
such Lender’s Lending Office. All payments received by (x) the Domestic Administrative Agent after
2:00 p.m. and (y) the Canadian Administrative Agent after 2:00 p.m. (Toronto time) shall in each
case be deemed received on the next succeeding Business Day and any applicable interest or fee
shall continue to accrue. Subject to the definition of “Interest Period”, if any payment to be
made by the Borrowers shall come due on a day other than a Business Day, payment shall be made on
the next following Business Day, and such extension of time shall be reflected in computing
interest or fees, as the case may be.

	 	(b)	 	(i) Funding by Lenders; Presumption by the Administrative Agent.
Unless the applicable Administrative Agent shall have received notice from a Lender
prior to the proposed date of any Borrowing of Eurodollar Rate Loans (or, in the case
of any Borrowing of Base Rate Loans, prior to 12:00 noon Eastern time on the date of
such Borrowing) that such Lender will not make available to the applicable
Administrative Agent such Lender’s share of such Borrowing, the applicable
Administrative Agent may assume that such Lender has made such share available on such
date in accordance with Section 2.02 (or, in the case of any Borrowing of Base
Rate Loans, that such Lender has made such share available in accordance with and at
the time required by Section 2.02) and may, in reliance upon such assumption,
make available to the applicable Borrower a corresponding amount. In such event, if a
Lender has not in fact made its share of the applicable Borrowing available to the
applicable Administrative Agent, then such Lender and the applicable Borrower severally
agree to pay to the applicable Administrative Agent forthwith on demand such
corresponding amount in immediately available funds with interest thereon, for each day
from and including the date such amount is made available to the applicable Borrower to
but excluding the date of payment to the applicable Administrative Agent, at (A) in the
case of a payment to be made by such Lender, the Overnight Rate, plus any
administrative, processing or similar fees customarily charged by the applicable
Administrative Agent in connection with the foregoing, and (B) in the case of a payment
to be made by the applicable Borrower, the interest rate applicable to Base Rate Loans.
If the applicable Borrower and such Lender shall pay such interest to the applicable
Administrative Agent for the same or an overlapping period, the applicable
Administrative Agent shall promptly remit to the applicable Borrower the amount of such
interest paid by the applicable Borrower for such period. If such Lender pays its
share of the applicable Borrowing to the applicable Administrative Agent, then the
amount so paid shall constitute such Lender’s Loan included in such Borrowing. Any
payment by the applicable Borrower shall be without prejudice to any claim the
applicable Borrower may have against a Lender that shall have failed to make such
payment to the applicable Administrative Agent.
	 
	 	(ii)	 	Payments by Borrower; Presumptions by Administrative Agent. Unless the
applicable Administrative Agent shall have received notice from the applicable
Borrower prior to the date on which any payment is due to the applicable
Administrative Agent for the account of the applicable Lenders or the applicable L/C
Issuer hereunder that the applicable Borrower will not make such payment, the
applicable Administrative Agent may assume that the applicable Borrower has made
such payment on such date in accordance herewith and may, in reliance upon such
assumption, distribute to the applicable Lenders or the applicable L/C Issuer, as
the case may be, the amount due. In such event, if the applicable Borrower has not
in fact made such payment, then each of the applicable Lenders or the applicable L/C
Issuer, as the case may be, severally agrees

53

 

	 	 	 	to repay to the applicable Administrative Agent forthwith on demand the amount so
distributed to such Lender or the applicable L/C Issuer, in immediately available
funds with interest thereon, for each day from and including the date such amount is
distributed to it to but excluding the date of payment to the applicable
Administrative Agent, at the Overnight Rate.

          A notice of the applicable Administrative Agent to any Lender or any Borrower with
respect to any amount owing under this subsection (b) shall be conclusive, absent manifest
error.

     (c) Failure to Satisfy Conditions Precedent. If any Lender makes available to the
applicable Administrative Agent, as the case may be, funds for any Loan to be made by such Lender
as provided in the foregoing provisions of this Article II, and such funds are not made
available to the applicable Borrower by the applicable Administrative Agent because the conditions
to the applicable Credit Extension set forth in Article V are not satisfied or waived in
accordance with the terms hereof, the applicable Administrative Agent shall return such funds (in
like funds as received from such Lender) to such Lender, without interest.

     (d) Obligations of Lenders Several. The obligations of the Lenders hereunder to make
Loans, to fund participations in Letters of Credit and to make payments pursuant to Section
11.04(c) are several and not joint. The failure of any Lender to make any Loan, to fund any
such participations or to make any payment under Section 11.04(c) on any date required
hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date,
and no Lender shall be responsible for the failure of any other Lender to so make its Loan, to
purchase its participation or to make its payment under Section 11.04(c).

     (e) Funding Source. Nothing herein shall be deemed to obligate any Lender to obtain
the funds for any Loan in any particular place or manner or to constitute a representation by any
Lender that it has obtained or will obtain the funds for any Loan in any particular place or
manner.

     (f) Allocation of Funds. If at any time insufficient funds are received by or are
available to an Administrative Agent to pay fully all amounts of principal and Domestic L/C
Borrowings, Canadian L/C Borrowings, interest and fees then due hereunder, such funds shall be
applied (i) first, toward costs and expenses (including all reasonable fees, expenses and
disbursements of any law firm or other counsel and amounts payable under Article III)
incurred by each Administrative Agent and each Lender, (ii) second, toward repayment of
interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with
the amounts of interest and fees then due to such parties, and (iii) third, toward
repayment of principal, Domestic L/C Borrowings and Canadian L/C Borrowings then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of principal, Domestic
L/C Borrowings and Canadian L/C Borrowings then due to such parties.

2.12 Sharing of Payments by Lenders.

     (a) If any Lender shall, by exercising any right of setoff or counterclaim or otherwise,
obtain payment in respect of any principal of or interest on any of the Loans made by it, or the
participations in L/C Obligations held by it resulting in such Lender’s receiving payment of a
proportion of the aggregate amount of such Loans or participations and accrued interest thereon
greater than its pro rata share thereof as provided herein, then the Lender
receiving such greater proportion shall (a) notify each Administrative Agent of such fact, and
(b) purchase (for cash at face value) participations in (1) Domestic Revolving Loans and
subparticipations in Domestic L/C Obligations of the other Lenders if such Lender is a Domestic
Lender and/or (2) the Canadian Revolving Loans and subparticipations in Canadian L/C Obligations of
the other Lenders if such Lender is a Canadian Lender, or make such other adjustments as

54

 

shall be equitable, so that the benefit of all such payments shall be shared by the Lenders,
as applicable, ratably in accordance with the aggregate amount of principal of and accrued interest
on their respective Loans and participations and other amounts owing them, provided that:

     (i) if any such participations or subparticipations are purchased and all or any
portion of the payment giving rise thereto is recovered, such participations or
subparticipations shall be rescinded and the purchase price restored to the extent of such
recovery, without interest; and

     (ii) the provisions of this Section shall not be construed to apply to (x) any payment
made by the Borrowers pursuant to and in accordance with the express terms of this Agreement
or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a
participation in any of its Loans or subparticipations in L/C Obligations to any assignee or
participant, other than to a Borrower or any Subsidiary thereof (as to which the provisions
of this Section shall apply).

     Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so
under applicable law, that any Lender acquiring a participation pursuant to the foregoing
arrangements may exercise against such Loan Party rights of setoff and counterclaim with respect to
such participation as fully as if such Lender were a direct creditor of such Loan Party in the
amount of such participation.

ARTICLE III

TAXES, YIELD PROTECTION AND ILLEGALITY

3.01 Taxes.

     (a) Payments Free of Taxes. Any and all payments by or on account of any obligation
of the Loan Parties hereunder or under any other Loan Document shall be made free and clear of and
without reduction or withholding for any Indemnified Taxes or Other Taxes; provided that if
any Loan Party shall be required by applicable law to deduct any Indemnified Taxes (including any
Other Taxes) from such payments, then (i) the sum payable shall be increased as necessary so that
after making all required deductions (including deductions applicable to additional sums payable
under this Section) each Administrative Agent, Lender or L/C Issuer, as the case may be, receives
an amount equal to the sum it would have received had no such deductions been made, (ii) such Loan
Party shall make such deductions and (iii) such Loan Party shall timely pay the full amount
deducted to the relevant Governmental Authority in accordance with applicable law.

     (b) Payment of Other Taxes by the Loan Parties. Without limiting the provisions of
subsection (a) above, the Loan Parties shall timely pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.

     (c) Indemnification by the Loan Parties. The Loan Parties shall indemnify each
Administrative Agent, each Lender and each L/C Issuer within ten (10) days after demand therefor,
for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other
Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by such
Administrative Agent, such Lender or such L/C Issuer, as the case may be, and any penalties,
interest and reasonable expenses arising therefrom or with respect thereto, whether or not such
Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or liability delivered to
the applicable Borrower by a Lender or an L/C Issuer

55

 

(with a copy to the applicable Administrative Agent), or by the applicable Administrative
Agent on its own behalf or on behalf of a Lender or an L/C Issuer, shall be conclusive absent
manifest error.

     (d) Evidence of Payments. As soon as practicable after any payment of Indemnified
Taxes or Other Taxes by any Loan Party to a Governmental Authority, the applicable Borrower shall
deliver to the applicable Administrative Agent the original or a certified copy of a receipt issued
by such Governmental Authority evidencing such payment, a copy of the return reporting such payment
or other evidence of such payment reasonably satisfactory to the applicable Administrative Agent.

     (e) Status of Lenders. Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which a Borrower is resident for
tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments
hereunder or under any other Loan Document shall deliver to the applicable Borrower (with a copy to
the applicable Administrative Agent), at the time or times prescribed by applicable law or
reasonably requested by such Borrower or the applicable 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. In addition, any Lender, if
requested by the applicable Borrower or the applicable Administrative Agent shall deliver such
other documentation prescribed by applicable law or reasonably requested by such Borrower or the
applicable Administrative Agent as will enable such Borrower or the applicable Administrative Agent
to determine whether or not such Lender is subject to backup withholding, withholding or
information reporting requirements.

     Without limiting the generality of the foregoing, in the event that a Borrower is resident for
tax purposes in the United States, any Foreign Lender shall deliver to such Borrower and the
applicable Administrative Agent (in such number of copies as shall be requested by the recipient)
on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and
from time to time thereafter upon the request of the applicable Borrower or the applicable
Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of
the following is applicable:

     (i) duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility
for benefits of an income tax treaty to which the United States is a party,

     (ii) duly completed copies of Internal Revenue Service Form W-8ECI,

     (iii) in the case of a Foreign Lender claiming the benefits of the exemption for
portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that
such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the
Code, (B) a “10 percent shareholder” of either Borrower within the meaning of section
881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section
881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form
W-8BEN, or

     (iv) any other form prescribed by applicable law as a basis for claiming exemption from
or a reduction in United States Federal withholding tax duly completed together with such
supplementary documentation as may be prescribed by applicable law to permit a Borrower to
determine the withholding or deduction required to be made.

     (f) Treatment of Certain Refunds. If an Administrative Agent, any Lender or any L/C
Issuer determines, in its sole discretion, that it has received a refund of any Taxes or Other
Taxes as to which it has been indemnified by any Loan Party or with respect to which any Loan Party
has paid additional amounts pursuant to this Section, it shall pay to such Loan Party an amount
equal to such refund (but only to the extent of indemnity payments made, or additional amounts
paid, by such Loan Party under this

56

 

Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all
out-of-pocket expenses of such Administrative Agent, such Lender or such L/C Issuer, as the case
may be, and without interest (other than any interest paid by the relevant Governmental Authority
with respect to such refund), provided that each Loan Party, upon the request of such
Administrative Agent, such Lender or such L/C Issuer, agrees to repay the amount paid over to such
Loan Party (plus any penalties, interest or other charges imposed by the relevant Governmental
Authority) to such Administrative Agent, such Lender or such L/C Issuer in the event such
Administrative Agent, such Lender or such L/C Issuer is required to repay such refund to such
Governmental Authority. This subsection shall not be construed to require either Administrative
Agent, any Lender or any L/C Issuer to make available its tax returns (or any other information
relating to its taxes that it deems confidential) to the Borrowers or any other Person.

3.02 Illegality.

     If any Lender determines that any Change in Law has made it unlawful, or that any Governmental
Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to
make, maintain or fund Eurodollar Rate Loans (whether denominated in U.S. Dollars, Canadian Dollars
or Euros) or to determine or charge interest rates based upon the Eurodollar Rate, or any
Governmental Authority has imposed material restrictions on the authority of such Lender to
purchase or sell, or to take deposits of, U.S. Dollars, Canadian Dollars or Euros in the applicable
interbank market, then, on notice thereof by such Lender to the applicable Borrower through the
applicable Administrative Agent any obligation of such Lender to make or continue Eurodollar Rate
Loans in the affected currency or currencies or, to convert Base Rate Loans to Eurodollar Rate
Loans, as applicable, shall be suspended until such Lender notifies the applicable Administrative
Agent and such Borrower that the circumstances giving rise to such determination no longer exist.
Upon receipt of such notice, the applicable Borrower shall, upon demand from such Lender (with a
copy to the applicable Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate
Loans of such Lender to Base Rate Loans, on the last day of the Interest Period therefor, if such
Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if
such Lender may not lawfully continue to maintain such Eurodollar Rate Loans. Upon any such
prepayment or conversion, the applicable Borrower shall also pay accrued interest on the amount so
prepaid or converted.

3.03 Inability to Determine Rates.

     If the Required Lenders determine that for any reason in connection with any request for a
Eurodollar Rate Loan or a conversion to or continuation thereof that (a) deposits (whether in U.S.
Dollars, Canadian Dollars or Euros) are not being offered to banks in the applicable offshore
interbank market for such currency for the applicable amount and Interest Period of such Eurodollar
Rate Loan, (b) adequate and reasonable means do not exist for determining the Eurodollar Rate for
any requested Interest Period with respect to a proposed Eurodollar Rate Loan (whether denominated
in U.S. Dollars, Canadian Dollars or Euros), or (c) the Eurodollar Rate for any requested Interest
Period with respect to a proposed Eurodollar Rate Loan does not adequately and fairly reflect the
cost to such Lenders of funding such Loan, the applicable Administrative Agent will promptly so
notify the applicable Borrower and each applicable Lender. Thereafter, the obligation of the
Lenders to make or maintain Eurodollar Rate Loans in the affected currency or currencies shall be
suspended until the applicable Administrative Agent revokes such notice. Upon receipt of such
notice, the applicable Borrower may revoke any pending request for a Borrowing of, conversion to or
continuation of Eurodollar Rate Loans in the affected currency or currencies or, failing that, will
be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in the
amount specified therein.

3.04  Increased Costs; Reserves on Eurodollar Rate Loans.

     (a) Increased Costs Generally. If any Change in Law shall:

     (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan,
insurance charge or similar requirement against assets of, deposits with or for the account
of, or credit extended or participated in by, any Lender (except (A) any reserve requirement
contemplated by Section 3.04(e) and (B) the requirements of the Bank of England and
the Financial Services Authority or the European Central Bank reflected in the Mandatory
Cost, other than as set forth below) or any L/C Issuer;

     (ii) subject any Lender or any L/C Issuer to any Tax of any kind whatsoever with
respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit,
any Eurodollar Rate Loan made by it, or change the basis of taxation of payments to such
Lender or such L/C Issuer in respect thereof (except for Indemnified Taxes or Other Taxes
covered by Section 3.01 and the imposition of, or any change in the rate of, any
Excluded Tax payable by such Lender or such L/C Issuer);

     (iii) result in the failure of the Mandatory Cost, as calculated hereunder, to
represent the cost to any Lender of complying with the requirements of the Bank of England
and/or the Financial Services Authority or the European Central Bank in relation to its
making, funding or maintaining Eurodollar Rate Loans; or

     (iv) impose on any Lender or any L/C Issuer or the London interbank market any other
condition, cost or expense affecting this Agreement, Eurodollar Rate Loans made by such
Lender, any Letter of Credit or any participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurodollar Rate Loan (or of maintaining its obligation to make any such Loan), or
to increase the cost to such Lender or such L/C Issuer of participating in, issuing or maintaining
any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of
Credit), or to reduce the amount of any sum received or receivable by such Lender or such L/C
Issuer hereunder (whether of principal, interest or any other amount) then, upon request of such
Lender or such L/C Issuer, the applicable Borrower will pay to such Lender or such L/C Issuer, as
the case may be, such additional amount or amounts as will compensate such Lender or such L/C
Issuer, as the case may be, for such additional costs incurred or reduction suffered.

     (b) Capital Requirements. If any Lender or any L/C Issuer determines that any Change
in Law affecting such Lender or such L/C Issuer or any Lending Office of such Lender or such
Lender’s or such L/C Issuer’s holding company, if any, regarding capital requirements has or would
have the effect of reducing the rate of return on such Lender’s or such L/C Issuer’s capital or on
the capital of such Lender’s or such L/C Issuer’s holding company, if any, as a consequence of this
Agreement, the Commitments of such Lender or the Loans made by or participations in Letters of
Credit held by, such Lender, the Letters of Credit issued by such L/C Issuer, to a level below that
which such Lender, such L/C Issuer or such Lender’s or such L/C Issuer’s holding company could have
achieved but for such Change in Law (taking into consideration such Lender’s or such L/C Issuer’s
policies and the policies of such Lender’s or such L/C Issuer’s holding company with respect to
capital adequacy), then from time to time the applicable Borrower will pay to such Lender or such
L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or
such L/C Issuer or such Lender’s or such L/C Issuer’s holding company for any such reduction
suffered.

58

 

     (c) Certificates for Reimbursement. A certificate of a Lender or any L/C Issuer
setting forth the amount or amounts necessary to compensate such Lender or such L/C Issuer or its
holding company, as the case may be, as specified in subsection (a) or (b) of this Section, and
delivered to the applicable Borrower shall be conclusive absent manifest error. The applicable
Borrower shall pay such Lender or such L/C Issuer, as the case may be, the amount shown as due on
any such certificate within ten (10) days after receipt thereof.

     (d) Delay in Requests. Failure or delay on the part of any Lender or any L/C Issuer
to demand compensation pursuant to the foregoing provisions of this Section shall not constitute a
waiver of such Lender’s or such L/C Issuer’s right to demand such compensation; provided
that no Borrower shall be required to compensate a Lender or an L/C Issuer pursuant to the
foregoing provisions of this Section for any increased costs incurred or reductions suffered more
than six months prior to the date that such Lender or such L/C Issuer, as the case may be, notifies
the applicable Borrower of the Change in Law giving rise to such increased costs or reductions and
of such Lender’s or such L/C Issuer’s intention to claim compensation therefor (except that, if the
Change in Law giving rise to such increased costs or reductions is retroactive, then the six month
period referred to above shall be extended to include the period of retroactive effect thereof).

     (e) Reserves on Eurodollar Rate Loans. The applicable Borrower shall pay to each
Lender, (i) as long as such Lender shall be required to maintain reserves with respect to
liabilities or assets consisting of or including Eurocurrency funds or deposits (currently known as
“Eurocurrency liabilities”), additional interest on the unpaid principal amount of each Eurodollar
Rate Loan equal to the actual costs of such reserves allocated to such Loan by such Lender (as
determined by such Lender in good faith, which determination shall be conclusive), and (ii) as long
as such Lender shall be required to comply with any reserve ratio requirement or analogous
requirement of any central banking or financial regulatory authority imposed in respect of the
maintenance of the Commitments or the funding of the Eurodollar Rate Loans, such additional costs
(expressed as a percentage per annum and rounded upwards, if necessary, to the nearest five decimal
points) equal to the actual costs allocated to such Commitment or Loan by such Lender (as
determined by such Lender in good faith, which determination shall be conclusive), which, in each
case, shall be due and payable on each date on which interest is payable on such Loan;
provided the applicable Borrower shall have received at least 10 days’ prior notice (with a
copy to the applicable Administrative Agent) of such additional interest or costs from such Lender.
If a Domestic Lender fails to give notice ten (10) days prior to the relevant Interest Payment
Date, such additional interest or costs shall be due and payable ten (10) days from receipt of such
notice.

3.05 Compensation for Losses.

     Upon demand of any Lender (with a copy to the applicable Administrative Agent) from time to
time, the applicable Borrower shall promptly compensate such Lender for and hold such Lender
harmless from any loss, cost or expense incurred by it as a result of:

     (a) any continuation, conversion, payment or prepayment of any Loan other than a Base
Rate Loan on a day other than the last day of the Interest Period for such Loan (whether
voluntary, mandatory, automatic, by reason of acceleration, or otherwise);

     (b) any failure by such Borrower (for a reason other than the failure of such Lender to
make a Loan) to prepay, borrow, continue or convert any Eurodollar Rate Loan on the date or
in the amount notified by such Borrower;

     (c) any failure by such Borrower to make payment of any Loan denominated in an
Alternative Currency on its scheduled date or any payment thereof in a different currency;
or

59

 

     (d) any assignment of a Eurodollar Rate Loan on a day other than the last day of the
Interest Period therefor as a result of a request by such Borrower pursuant to Section
11.13;

including any loss of anticipated profits and any loss or expense arising from the
liquidation or reemployment of funds obtained by it to maintain such Loan or from fees
payable to terminate the deposits from which such funds were obtained. The applicable
Borrower shall also pay any customary administrative fees charged by such Lender in
connection with the foregoing.

     For purposes of calculating amounts payable by a Borrower to the Lenders under this
Section 3.05, each Lender shall be deemed to have funded each Eurodollar Rate Loan made by
it at the Eurodollar Rate for such Loan by a matching deposit or other borrowing in the London
interbank eurodollar market for a comparable amount and for a comparable period, whether or not
such Eurodollar Rate Loan was in fact so funded.

3.06 Mitigation Obligations; Replacement of Lenders.

     (a) Designation of a Different Lending Office. If any Lender requests compensation
under Section 3.04, or either Borrower is required to pay any additional amount to any
Lender, any L/C Issuer or any Governmental Authority for the account of any Lender or any L/C
Issuer pursuant to Section 3.01, or if any Lender gives a notice pursuant to
Section 3.02, then such Lender or such L/C Issuer shall, as applicable, use reasonable
efforts to designate a different Lending Office for funding or booking its Loans hereunder or to
assign its rights and obligations hereunder to another of its offices, branches or affiliates, if,
in the judgment of such Lender or such L/C Issuer, such designation or assignment (i) would
eliminate or reduce amounts payable pursuant to Section 3.01 or 3.04, as the case
may be, in the future, or eliminate the need for the notice pursuant to Section 3.02, as
applicable, and (ii) in each case, would not subject such Lender or such L/C Issuer, as the case
may be, to any unreimbursed cost or expense and would not otherwise be disadvantageous to such
Lender or such L/C Issuer, as the case may be. Such Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender or any L/C Issuer in connection with any such designation
or assignment.

     (b) Replacement of Lenders. If any Lender requests compensation under
Section 3.04, or if a Borrower is required to pay any additional amount to any Lender or
any Governmental Authority for the account of any Lender pursuant to Sections 3.01,
3.02 or 3.04, such Borrower may replace such Lender in accordance with Section
11.13.

3.07 Survival.

     All of the obligations of the Borrowers under this Article III shall survive
termination of the Aggregate Commitments and repayment of all other Obligations hereunder and
resignation of any Administrative Agent.

presentment, demand of payment, protest and all notices whatsoever, and any requirement that any
Administrative Agent or any Lender exhaust any right, power or remedy or proceed against any Person
under any of the Loan Documents, any Swap Contract or any Treasury Management Agreement between any
Loan Party and any Lender, or any Affiliate of a Lender, or any other agreement or instrument
referred to in the Loan Documents or such Swap Contracts or such Treasury Management Agreements, or

letter is currently being processed by the IRS with respect thereto and, to the best knowledge of

contemplated hereby and the negotiation of this Agreement or delivered hereunder or under any other
Loan Document (in each case, as modified or supplemented by other information so furnished)
contains any material misstatement of fact or omits to state any material fact necessary to make
the statements therein, in the light of the circumstances under which they were made, not
misleading; provided that, with respect to any projected financial information, each Loan
Party represents only that such projected financial information was prepared in good faith based
upon assumptions believed to be reasonable at the time.

(a) such requirement of Law or order, writ, injunction or decree is being contested in good faith
by appropriate proceedings diligently conducted or (b) the failure to comply therewith, either
individually or in the aggregate, could not reasonably be expected to have a Material Adverse
Effect.

knowledge of the Loan Parties, the use of any IP Rights by any Loan Party or any of its
Subsidiaries or the granting of a right or a license in respect of any IP Rights from any Loan
Party or any of its Subsidiaries does not infringe on the rights of any Person. As of the Closing

by the proper Person. Each Administrative Agent also may rely upon any statement made to it orally
or by telephone and believed by it to have been made by the proper Person, and shall not incur any

unless the applicable Administrative Agent shall have received notice to the contrary from such
Lender or such L/C Issuer prior to the making of such Loan or the issuance of such Letter of
Credit, as applicable. Each Administrative Agent may consult with legal counsel (who may be

resignation hereunder and under the other Loan Documents, the provisions of this Article X
and Section 11.04 shall continue in effect for the benefit of such retiring Domestic
Administrative Agent and/or Canadian Administrative Agent, their sub-agents and their respective
Related Parties in respect of any actions taken or omitted to be taken by any of them while the
retiring Domestic Administrative Agent and/or Canadian Administrative Agent was acting as Domestic

become vested with all of the rights, powers, privileges and duties of such retiring Domestic L/C
Issuer, and (b) such retiring Domestic L/C Issuer shall be discharged from all of their respective

     Each Lender and each L/C Issuer acknowledges that it has, independently and without reliance
upon the Domestic Administrative Agent, the Canadian Administrative Agent or any other Lender or
any of their Related Parties and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender
and each L/C Issuer also acknowledges that it will, independently and without reliance upon the
Domestic Administrative Agent, the Canadian Administrative Agent or any other Lender or any of
their Related Parties and based on such documents and information as it shall from time to time
deem appropriate, continue to make its own decisions in taking or not taking action under or based
upon this Agreement, any other Loan Document or any related agreement or any document furnished
hereunder or thereunder.

10.08 No Other Duties, Etc.

96

 

the applicable Administrative Agent and, in the event that the applicable Administrative Agent
shall consent to the making of such payments directly to the Lenders and the L/C Issuers to pay to
the applicable Administrative Agent any amount due for the reasonable compensation, expenses,
disbursements and advances of such Administrative Agent and its agents and counsel, and any other
amounts due such Administrative Agent under Sections 2.09 and 11.04.

     Nothing contained herein shall be deemed to authorize any Administrative Agent to authorize or
consent to or accept or adopt on behalf of any Lender or any L/C Issuer any plan of reorganization,
arrangement, adjustment or composition affecting the Obligations or the Canadian Obligations, as
appropriate or the rights of any Lender or any L/C Issuer or to authorize any Administrative Agent
to vote in respect of the claim of any Lender in any such proceeding.

11.02 Notices; Effectiveness; Electronic Communication.

     (a) Notices Generally. Except in the case of notices and other communications
expressly permitted to be given by telephone (and except as provided in subsection (b) below), all
notices and other communications provided for herein shall be in writing and shall be delivered by
hand or overnight courier service, mailed by certified or registered mail or sent by telecopier as
follows, and all notices and other communications expressly permitted hereunder to be given by
telephone shall be made to the applicable telephone number, as follows:

     (i) if to EMS or any other Loan Party, an Administrative Agent, or an L/C Issuer, to
the address, telecopier number, electronic mail address or telephone number specified for
such Person on Schedule 11.02; and

     (ii) if to any other Lender, to the address, telecopier number, electronic mail address
or telephone number specified in its Administrative Questionnaire.

Notices sent by hand or overnight courier service, or mailed by certified or registered mail, shall
be deemed to have been given when received; notices sent by telecopier shall be deemed to have been
given when sent (except that, if not given during normal business hours for the recipient, shall be
deemed to have been given at the opening of business on the next business day for the recipient).
Notices delivered through electronic communications to the extent provided in subsection (b) below,
shall be effective as provided in such subsection (b).

     (b) Electronic Communications. Notices and other communications to the Lenders and
the L/C Issuers hereunder may be delivered or furnished by electronic communication (including
e-mail and Internet or intranet websites) pursuant to procedures approved by the applicable
Administrative Agent; provided that the foregoing shall not apply to notices to any Lender
or any L/C Issuer pursuant to

99

 

Article II if such Lender or such L/C Issuer, as applicable, has notified the applicable
Administrative Agent that it is incapable of receiving notices under such Article by electronic
communication. The applicable Administrative Agent or EMS may, in its discretion, agree to accept
notices and other communications to it hereunder by electronic communications pursuant to
procedures approved by it; provided that approval of such procedures may be limited to
particular notices or communications.

     Unless the applicable Administrative Agent otherwise prescribes, (i) notices and other
communications sent to an e-mail address shall be deemed received upon the sender’s receipt of an
acknowledgement from the intended recipient (such as by the “return receipt requested” function, as
available, return e-mail or other written acknowledgement), provided that if such notice or
other communication is not sent during the normal business hours of the recipient, such notice or
communication shall be deemed to have been sent at the opening of business on the next business day
for the recipient, and (ii) notices or communications posted to an Internet or intranet website
shall be deemed received upon the deemed receipt by the intended recipient at its e-mail address as
described in the foregoing clause (i) of notification that such notice or communication is
available and identifying the website address therefor.

     (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 BORROWER MATERIALS OR THE ADEQUACY OF THE
PLATFORM, AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS IN OR OMISSIONS FROM THE BORROWER MATERIALS.
NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING 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 ANY AGENT PARTY IN CONNECTION WITH THE BORROWER MATERIALS OR THE
PLATFORM. In no event shall any Administrative Agent or any of its Related Parties (collectively,
the “Agent Parties”) have any liability to the Borrowers, any Lender, any L/C Issuer, or
any other Person for losses, claims, damages, liabilities or expenses of any kind (whether in tort,
contract or otherwise) arising out of any Borrower’s, or any Administrative Agent’s transmission of
Borrower Materials through the Internet, except to the extent that such losses, claims, damages,
liabilities or expenses result from the gross negligence or willful misconduct of such Agent Party;
provided, however, that in no event shall any Agent Party have any liability to any
Borrower, any Lender, any L/C Issuer, or any other Person for indirect, special, incidental,
consequential or punitive damages (as opposed to direct or actual damages).

     (d) Change of Address, Etc. Any Borrower, any Administrative Agent or any L/C Issuer
may change its address, telecopier or telephone number for notices and other communications
hereunder by notice to the other parties hereto. Each Lender may change its address, telecopier or
telephone number for notices and other communications hereunder by notice to the applicable
Borrower, the applicable Administrative Agent or the applicable L/C Issuer. In addition, each
Lender agrees to notify the applicable Administrative Agent from time to time to ensure that such
Administrative Agent has on record (i) an effective address, contact name, telephone number,
telecopier number and electronic mail address to which notices and other communications may be sent
and (ii) accurate wire instructions for such Lender.

     (e) Reliance by Administrative Agents, L/C Issuers and Lenders. Each Administrative
Agent, each L/C Issuer and the Lenders shall be entitled to rely and act upon any notices
(including telephonic Loan Notices) purportedly given by or on behalf of any Loan Party even if (i)
such notices were not made in a manner specified herein, were incomplete or were not preceded or
followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by
the recipient, varied from any confirmation thereof. The Borrowers shall indemnify each
Administrative Agent, each L/C Issuer,

100

 

each Lender and the Related Parties of each of them from all losses, costs, expenses and
liabilities resulting from the reliance by such Person on each notice purportedly given by or on
behalf of a Borrower. All telephonic notices to and other telephonic communications with each
Administrative Agent may be recorded by such Administrative Agent, and each of the parties hereto
hereby consents to such recording.

11.03 No Waiver; Cumulative Remedies; Enforcement.

     No failure by any Lender, any L/C Issuer or any Administrative Agent to exercise, and no delay
by any such Person in exercising, any right, remedy, power or privilege hereunder shall operate as
a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege
hereunder preclude any other or further exercise thereof or the exercise of any other right,
remedy, power or privilege. The rights, remedies, powers and privileges herein provided are
cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

11.04 Expenses; Indemnity; Damage Waiver.

     (a) Costs and Expenses. The Loan Parties shall pay (i) all reasonable out-of-pocket
expenses incurred by the Administrative Agents and their Affiliates (including the reasonable fees,
charges and disbursements of counsel for the Administrative Agents), in connection with the
syndication of the credit facilities provided for herein, the preparation, negotiation, execution,
delivery and administration of this Agreement and the other Loan Documents or any amendments,
modifications or waivers of the provisions hereof or thereof (whether or not the transactions
contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses
incurred by an L/C Issuer in connection with the issuance, amendment, renewal or extension of any
Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket expenses incurred
by any Administrative Agent, any Lender or any L/C Issuer (including the reasonable fees, charges
and disbursements of any counsel for any Administrative Agent, any Lender or any L/C Issuer), and
shall pay all reasonable fees and time charges for attorneys who may be employees of any
Administrative Agent, any Lender or any L/C Issuer, in connection with the enforcement or
protection of its rights (A) in connection with this Agreement and the other Loan Documents,
including its rights under this Section, or (B) in connection with the Loans made or Letters of
Credit issued hereunder, including all such out-of-pocket expenses incurred during any workout,
restructuring or negotiations in respect of such Loans or Letters of Credit; provided that
the Borrowers shall not be required to reimburse the fees and expenses of outside counsel to any
Lender unless in the written opinion of outside counsel to such Lender reasonably acceptable to the
Borrowers, (a) the representation by outside counsel to the Administrative Agents would be
inappropriate due to the existence of an actual conflict between either Administrative Agent and
such Lender, in which case the Borrowers shall be required to reimburse the fees and expenses of
one outside counsel to all the Lenders and (b) the representation by one outside counsel to all the
Lenders would be inappropriate due to the existence of an actual conflict between such Lender and
another Lender, in which case the Borrowers shall be required to reimburse the fees and expenses of
one outside counsel to such Lender.

     (b) Indemnification by the Loan Parties. The Loan Parties shall indemnify each
Administrative Agent (and any sub-agent thereof), each Lender, each L/C Issuer and each Related
Party of any of the foregoing Persons (each such Person being called an “Indemnitee”)
against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities
and related expenses (including the reasonable fees, charges and disbursements of any counsel for
any Indemnitee), other than Taxes, and shall indemnify and hold harmless each Indemnitee from all
reasonable fees and time charges and disbursements for attorneys who may be employees of any
Indemnitee, incurred by any Indemnitee or asserted against any Indemnitee by any third party or by
EMS or any other Loan Party arising out of, in connection with, or as a result of (i) the execution
or delivery of this Agreement, any other Loan

101

 

Document or any agreement or instrument contemplated hereby or thereby, the performance by the
parties hereto of their respective obligations hereunder or thereunder, the consummation of the
transactions contemplated hereby or thereby, or, in the case of the Domestic Administrative Agent
(and any sub-agent thereof) and its Related Parties only, the Canadian Administrative Agent (and
any sub-agent thereof) and its Related Parties only, the administration of this Agreement and the
other Loan Documents and/or the syndication of the facilities contemplated by this Agreement
(including in respect of any matters addressed in Section 3.01), (ii) any Loan or Letter of
Credit or the use or proposed use of the proceeds therefrom (including any refusal by an L/C Issuer
to honor a demand for payment under a Letter of Credit if the documents presented in connection
with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual
or alleged presence or release of Hazardous Materials on or from any property owned or operated by
a Loan Party or any of its Subsidiaries, or any Environmental Liability related in any way to a
Loan Party or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation,
investigation or proceeding relating to any of the foregoing, whether based on contract, tort or
any other theory, whether brought by a third party or by EMS or any other Loan Party, and
regardless of whether any Indemnitee is a party thereto, in all cases, whether or not caused by or
arising, in whole or in part, out of the comparative, contributory or sole negligence of the
Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be available to
the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by
a court of competent jurisdiction by final and nonappealable judgment to have resulted from the
gross negligence or willful misconduct of such Indemnitee, or (y) result from a claim brought by
EMS or any other Loan Party against an Indemnitee for material breach of such Indemnitee’s
obligations hereunder or under any other Loan Document, if EMS or such other Loan Party has
obtained a final and nonappealable judgment in its favor on such claim as determined by a court of
competent jurisdiction.

     (c) Reimbursement by Lenders. To the extent that the Loan Parties for any reason fail
to indefeasibly pay any amount required under subsection (a) or (b) of this Section to be paid by
them to any Administrative Agent (or any sub-agent thereof), any L/C Issuer or any Related Party of
any of the foregoing, each Lender severally agrees to pay to the applicable Administrative Agent
(or any such sub-agent), the applicable L/C Issuer or such Related Party, as the case may be, such
Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense
or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed
expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was
incurred by or asserted against the applicable Administrative Agent (or any sub-agent thereof), or
the applicable L/C Issuer in its capacity as such, or against any Related Party of any of the
foregoing acting for the applicable Administrative Agent (or any sub-agent thereof), or the
applicable L/C Issuer in connection with such capacity. The obligations of the Lenders under this
subsection (c) are subject to the provisions of Section 2.11(d).

     (d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by
applicable law, no Loan Party shall assert, and each Loan Party hereby waives, any claim against
any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive
damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result
of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the
transactions contemplated hereby or thereby, any Loan or Letter of Credit or the use of the
proceeds thereof. No Indemnitee referred to in subsection (b) above shall be liable for any
damages arising from the use by unintended recipients of any information or other materials
distributed by it through telecommunications, electronic or other information transmission systems
in connection with this Agreement or the other Loan Documents or the transactions contemplated
hereby or thereby; except to the extent that such special, indirect, consequential or punitive
damages (x) are determined by a court of competent jurisdiction by final and nonappealable judgment
to have resulted from the gross negligence or willful misconduct of such Indemnitee, (y) result
from a claim brought by EMS or any other Loan Party against an Indemnitee for material breach of
such Indemnitee’s obligations hereunder or under any other Loan Document, if EMS or such Loan Party
has

102

 

obtained a final and nonappealable judgment in its favor on such claim as determined by a
court of competent jurisdiction.

     (e) Payments. All amounts due under this Section shall be payable not later than ten
(10) Business Days after demand therefor.

     (f) Survival. The agreements in this Section 11.04 shall survive the
resignation of the Domestic Administrative Agent, the Canadian Administrative Agent, and any L/C
Issuer, the replacement of any Lender, the termination of the Commitments and the repayment,
satisfaction or discharge of all the other Obligations.

11.05 Payments Set Aside.

     To the extent that any payment by or on behalf of any Loan Party is made to any Administrative
Agent, any L/C Issuer or any Lender, or any Administrative Agent, any L/C Issuer or any Lender
exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof
is subsequently invalidated, declared to be fraudulent or preferential, set aside or required
(including pursuant to any settlement entered into by such Administrative Agent, such L/C Issuer or
such Lender in its discretion) to be repaid to a trustee, receiver or any other party, in
connection with any proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of
such recovery, the obligation or part thereof originally intended to be satisfied shall be revived
and continued in full force and effect as if such payment had not been made or such setoff had not
occurred, and (b) each Lender and each L/C Issuer severally agrees to pay to the applicable
Administrative Agent upon demand its applicable share (without duplication) of any amount so
recovered from or repaid by such Administrative Agent plus interest thereon from the date of such
demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from
time to time in effect. The obligations of the Lenders and the L/C Issuers under clause (b) of the
preceding sentence shall survive the payment in full of the Obligations and the termination of this
Agreement.

     11.06 Successors and Assigns.

     (a) Successors and Assigns Generally. The provisions of this Agreement and the other
Loan Documents shall be binding upon and inure to the benefit of the parties hereto and thereto and
their respective successors and assigns permitted hereby, except that neither EMS nor any other
Loan Party may assign or otherwise transfer any of its rights or obligations hereunder
or thereunder without the prior written consent of the applicable Administrative Agent and each
Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder
except (i) to an Eligible Assignee in accordance with the provisions of subsection (b) of this
Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this
Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions
of subsection (f) of this Section (and any other attempted assignment or transfer by any party
hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be
construed to confer upon any Person (other than the parties hereto, their respective successors and
assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section
and, to the extent expressly contemplated hereby, the Related Parties of each of the Domestic
Administrative Agent, the Canadian Administrative Agent, the L/C Issuers and the Lenders) any legal
or equitable right, remedy or claim under or by reason of this Agreement.

     (b) Assignments by Lenders. Any Lender may at any time assign to one or more Eligible
Assignees all or a portion of its rights and obligations under this Agreement and the other Loan
Documents (including all or a portion of its Domestic Revolving Commitment, Canadian Revolving
Commitment and the Loans (including for purposes of this subsection (b), participations in L/C

103

 

Obligations) at the time owing to it); provided that any such assignment shall be
subject to the following conditions:

	 	(i)	 	Minimum Amounts.

     (A) in the case of an assignment of the entire remaining amount of the
assigning Lender’s Domestic Revolving Commitment or Canadian Revolving Commitment
and the Loans at the time owing to it or in the case of an assignment to a Lender or
an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned;

     (B) in any case not described in subsection (b)(i)(A) of this Section, the
aggregate amount of the Domestic Revolving Commitment or the Canadian Revolving
Commitment (which for this purpose includes Loans outstanding thereunder) or, if the
Domestic Revolving Commitment or the Canadian Revolving Commitment is not then in
effect, the principal outstanding balance of the Loans of the assigning Lender
subject to each such assignment, determined as of the date the Assignment and
Assumption with respect to such assignment is delivered to the applicable
Administrative Agent or, if “Trade Date” is specified in the Assignment and
Assumption, as of the Trade Date, shall not be less than US$5,000,000, in the case
of an assignment of Domestic Revolving Loans, and CAN$5,000,000, in the case of an
assignment of Canadian Revolving Loans, unless the respective Administrative Agent
and, so long as no Event of Default has occurred and is continuing, EMS otherwise
consents (each such consent not to be unreasonably withheld or delayed);
provided, however, that concurrent assignments to members of an
Assignee Group and concurrent assignments from members of an Assignee Group to a
single Eligible Assignee (or to an Eligible Assignee and members of its Assignee
Group) will be treated as a single assignment for purposes of determining whether
such minimum amount has been met;

       (ii) Required Consents. No consent shall be required for any assignment except
to the extent required by subsection (b)(i)(B) of this Section and, in addition:

     (A) the consent of EMS (such consent not to be unreasonably withheld or
delayed) shall be required unless (1) an Event of Default has occurred and is
continuing at the time of such assignment or (2) such assignment is to a Lender, an
Affiliate of a Lender or an Approved Fund;

     (B) the consent of the Domestic Administrative Agent (such consent not to be
unreasonably withheld or delayed) shall be required for assignments in respect of
Domestic Revolving Commitments if such assignment is to a Person that is not a
Lender with a Domestic Revolving Commitment, an Affiliate of such Lender or an
Approved Fund with respect to such Lender;

     (C) the consent of the Canadian Administrative Agent (such consent not to be
unreasonably withheld or delayed) shall be required for assignments in respect of
the Canadian Revolving Commitments if such assignment is to a Person that is not a
Lender with a Canadian Revolving Commitment, an Affiliate of such Lender or an
Approved Fund with respect to such Lender; and

     (D) the consent of the Domestic L/C Issuer or the Canadian L/C Issuer shall be
required for any assignment that increases the obligation of the assignee to
participate

104

 

in exposure under one or more Domestic Letters of Credit or Canadian Letters of
Credit, respectively (whether or not such Letters of Credit are then outstanding).

     (iii) Assignment and Assumption. The parties to each assignment shall execute
and deliver to the applicable Administrative Agent an Assignment and Assumption, together
with a processing and recordation fee in the amount of US$3,500; provided,
however, that the applicable Administrative Agent may, in its sole discretion, elect
to waive such processing and recordation fee in the case of any assignment. The assignee,
if it is not a Lender, shall deliver to the applicable Administrative Agent an
Administrative Questionnaire.

     (iv) No Assignment to Borrowers. No such assignment shall be made to either of
the Borrowers or any of the Borrowers’ Affiliates or Subsidiaries.

     (v) No Assignment to Natural Persons. No such assignment shall be made to a
natural person.

     (vi) Canadian Revolving Commitment: No such assignment of the Canadian
Revolving Commitments shall be made to a Person unable to fulfill all obligations of a
Canadian Lender under the terms of this Agreement (including, but not limited to, the
obligation to make Canadian Loans in Canadian Dollars) in accordance with the requirements
of the Bank Act (Canada).

     Subject to acceptance and recording thereof by the applicable Administrative Agent pursuant to
subsection (c) of this Section, from and after the effective date specified in each Assignment and
Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the
interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender
under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest
assigned by such Assignment and Assumption, be released from its obligations under this Agreement
(and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and
obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of Sections 3.01, 3.04, 3.05 and
11.04 with respect to facts and circumstances occurring prior to the effective date of such
assignment). Upon request, the applicable Borrower (at its expense) shall execute and deliver a
Note to the assignee Lender. Any assignment or transfer by a Lender of rights or obligations under
this Agreement that does not comply with this subsection shall be treated for purposes of this
Agreement as a sale by such Lender of a participation in such rights and obligations in accordance
with Section 11.06(d).

     (c) Register. The applicable Administrative Agent, acting solely for this purpose as
an agent of the applicable Borrower, shall maintain a copy of each Assignment and Assumption
delivered to it and a register for the recordation of the names and addresses of the Lenders, and
the Commitments of, and principal amounts of the Loans and L/C Obligations owing to, each such
Lender pursuant to the terms hereof from time to time (each, a “Register”). The entries in
each Register shall be conclusive, and the Borrowers, the Administrative Agents and the Lenders may
treat each Person whose name is recorded in such Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. Each
Register shall be available for inspection by each of the Borrowers and the L/C Issuers at any
reasonable time and from time to time upon reasonable prior notice.

     (d) Participations. Any Lender may at any time, without the consent of, or notice to,
the applicable Borrower or the applicable Administrative Agent, sell participations to any Person
(other than a natural person or the Borrowers or any of the Borrowers’ Affiliates or Subsidiaries)
(each, a

105

 

“Participant”) in all or a portion of such Lender’s rights and/or obligations under
this Agreement (including all or a portion of its Domestic Revolving Commitment, the Canadian
Revolving Commitment and/or the Loans (including such Lender’s participations in L/C Obligations)
owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations and (iii) the Borrowers, the applicable Administrative Agent, the
Lenders and the L/C Issuers 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,
waiver or other modification described in the first proviso to Section 11.01 that affects
such Participant. Subject to subsection (e) of this Section, EMS agrees that each Participant
shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 to the
same extent as if it were a Lender and had acquired its interest by assignment pursuant to
subsection (b) of this Section. To the extent permitted by law, each Participant also shall be
entitled to the benefits of Section 11.08 as though it were a Lender, provided such
Participant agrees to be subject to Section 2.12 as though it were a Lender.

     (e) Limitations upon Participant Rights. A Participant shall not be entitled to
receive any greater payment under Section 3.01 or 3.04 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 a Foreign Lender if it were a Lender shall not be entitled to
the benefits of Section 3.01 unless the applicable Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the benefit of the
Borrowers, to comply with Section 3.01(e) as though it were a Lender.

     (f) Certain Pledges. Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement (including under its Note, if any) to
secure obligations of such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender
from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as
a party hereto.

     (g) Electronic Execution of Assignments. The words “execution,” “signed,”
“signature,” and words of like import in any Assignment and Assumption or in any amendment or other
modification hereof (including waivers and consents) shall be deemed to include electronic
signatures or the keeping of records in electronic form, each of which shall be of the same legal
effect, validity or enforceability as a manually executed signature or the use of a paper-based
recordkeeping system, as the case may be, to the extent and as provided for in any applicable law,
including the Federal Electronic Signatures in Global and National Commerce Act, the New York State
Electronic Signatures and Records Act, or any other similar state laws based on the Uniform
Electronic Transactions Act.

     (h) Resignation after Assignment. Notwithstanding anything to the contrary contained
herein, if at any time (1) Bank of America assigns all of its Domestic Revolving Commitments and
Domestic Revolving Loans pursuant to subsection (b) above, Bank of America may upon 30 days’ notice
to EMS and the Domestic Lenders, resign as Domestic L/C Issuer, and (2) Bank of America, acting
through its Canada branch assigns all of its Canadian Revolving Commitments and Canadian Revolving
Loans pursuant to subsection (b) above, Bank of America, acting through its Canada branch may upon
30 days’ notice to the Canadian Borrower and the Canadian Lenders, resign as Canadian L/C Issuer.
In the event of any such resignation as Domestic L/C Issuer or Canadian L/C Issuer, the applicable
Borrower shall be entitled to appoint from among the Lenders a successor Domestic L/C Issuer or
Canadian L/C Issuer hereunder, as applicable; provided, however, that no failure by
a Borrower to appoint any such

106

 

successor shall affect the resignation of Bank of America or Bank of America, acting through
its Canada branch, as applicable, as Domestic L/C Issuer or Canadian L/C Issuer. If Bank of
America or Bank of America, acting through its Canada branch, as applicable, resigns as Domestic
L/C Issuer or Canadian L/C Issuer, it shall retain all the rights, powers, privileges and duties of
Domestic L/C Issuer or Canadian L/C Issuer, as applicable, hereunder with respect to all Domestic
Letters of Credit or Canadian Letters of Credit outstanding as of the effective date of its
resignation as Domestic L/C Issuer or Canadian L/C Issuer and all Domestic L/C Obligations or
Canadian L/C Obligations, as applicable, with respect thereto (including the right to require the
Lenders to make Base Rate Loans or fund risk participations in Unreimbursed Amounts pursuant to
Section 2.03(c)). Upon the appointment of a successor L/C Issuer, (a) such successor shall
succeed to and become vested with all of the rights, powers, privileges and duties of the retiring
L/C Issuer, and (b) the successor L/C Issuer shall issue letters of credit in substitution for the
Letters of Credit, if any, outstanding at the time of such succession or make other arrangements
satisfactory to such Lender to effectively assume the obligations of such Lender with respect to
such Letters of Credit.

11.07 Treatment of Certain Information; Confidentiality.

     Each Administrative Agent, the Lenders and the L/C Issuers agrees to maintain the
confidentiality of the Information (as defined below), except that Information may be disclosed (a)
to its Affiliates and to its and its Affiliates’ respective partners, directors, officers,
employees, agents, trustees, advisors and representatives (it being understood that the Persons to
whom such disclosure is made will be informed of the confidential nature of such Information and
instructed to keep such Information confidential), (b) to the extent requested by any regulatory
authority purporting to have jurisdiction over it (including any self-regulatory authority, such as
the National Association of Insurance Commissioners), (c) to the extent required by applicable laws
or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in
connection with the exercise of any remedies hereunder or under any other Loan Document or any
action or proceeding relating to this Agreement or any other Loan Document or the enforcement of
rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the
same as those of this Section, to (i) any assignee of or Participant in, or any prospective
assignee of or Participant in, any of its rights or obligations under this Agreement, (ii) any
pledge referred to in Section 11.06(f) or (iii) any actual or prospective counterparty (or
its advisors) to any swap or derivative transaction relating to the Borrowers and their
obligations, (g) with the consent of EMS or (h) to the extent such Information (x) becomes publicly
available other than as a result of a breach of this Section or (y) becomes available to either
Administrative Agent, any Lender, any L/C Issuer or any of their respective Affiliates on a
nonconfidential basis from a source other than the Borrowers.

     For purposes of this Section, “Information” means all information received from any
Borrower or any Subsidiary relating to any Borrower or any Subsidiary or any of their respective
businesses, other than any such information that is available to either Administrative Agent, any
Lender or any L/C Issuer on a nonconfidential basis prior to disclosure by any Borrower or any
Subsidiary. Any Person required to maintain the confidentiality of Information as provided in this
Section shall be considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such Information as such
Person would accord to its own confidential information.

     Each of the Administrative Agents, the Lenders and the L/C Issuers acknowledges that (a) the
Information may include material non-public information concerning EMS or a Subsidiary, as the case
may be, (b) it has developed compliance procedures regarding the use of material non-public
information and (c) it will handle such material non-public information in accordance with
applicable Law, including Federal and state securities laws.

107

 

11.08 Right of Setoff.

     If an Event of Default shall have occurred and be continuing, each Lender, each L/C Issuer,
and each of their respective Affiliates is hereby authorized at any time and from time to time,
after obtaining the prior written consent of the Administrative Agents, to the fullest extent
permitted by applicable law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final, in whatever currency) at any time held and other obligations (in
whatever currency) at any time owing by such Lender, such L/C Issuer or any such Affiliate to or
for the credit or the account of the Borrowers or any other Loan Party against any and
all of the obligations of the applicable Borrower or such Loan Party now or hereafter existing
under this Agreement or any other Loan Document to such Lender or such L/C Issuer, irrespective of
whether or not such Lender or such L/C Issuer shall have made any demand under this Agreement or
any other Loan Document and although such obligations of such Borrower or such Loan Party may be
contingent or unmatured or are owed to a branch or office of such Lender or such L/C Issuer
different from the branch or office holding such deposit or obligated on such indebtedness. The
rights of each Lender, each L/C Issuer and their respective Affiliates under this Section are in
addition to other rights and remedies (including other rights of setoff) that such Lender, such L/C
Issuer or their respective Affiliates may have. Each Lender and each L/C Issuer agrees to notify
the applicable Borrower and the applicable Administrative Agent promptly after any such setoff and
application, provided that the failure to give such notice shall not affect the validity of
such setoff and application.

11.09 Interest Rate Limitation.

     Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or
agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious
interest permitted by applicable Law (the “Maximum Rate”). If the Domestic Administrative
Agent, the Canadian Administrative Agent or any Lender shall receive interest in an amount that
exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if
it exceeds such unpaid principal, refunded to the applicable Borrower. In determining whether the
interest contracted for, charged, or received by the Domestic Administrative Agent, the Canadian
Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted
by applicable Law, (a) characterize any payment that is not principal as an expense, fee, or
premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c)
amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest
throughout the contemplated term of the Obligations hereunder.

11.10 Counterparts; Integration; Effectiveness.

     This Agreement may be executed in counterparts (and by different parties hereto in different
counterparts), each of which shall constitute an original, but all of which when taken together
shall constitute a single contract. This Agreement and the other Loan Documents constitute the
entire contract among the parties relating to the subject matter hereof and supersede any and all
previous agreements and understandings, oral or written, relating to the subject matter hereof.
Except as provided in Section 5.01, this Agreement shall become effective when it shall
have been executed by the Domestic Administrative Agent and the Canadian Administrative Agent and
when the Domestic Administrative Agent shall have received counterparts hereof that, when taken
together, bear the signatures of each of the other parties hereto. Delivery of an executed
counterpart of a signature page of this Agreement by telecopy or other electronic imaging means
shall be effective as delivery of a manually executed counterpart of this Agreement.

108

 

11.11 Survival of Representations and Warranties.

     All representations and warranties made hereunder and in any other Loan Document or other
document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive
the execution and delivery hereof and thereof. Such representations and warranties have been or
will be relied upon by each Administrative Agent and each Lender, regardless of any investigation
made by any Administrative Agent or any Lender or on their behalf and notwithstanding that any
Administrative Agent or any Lender may have had notice or knowledge of any Default at the time of
any Credit Extension, and shall continue in full force and effect as long as any Loan or any other
Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain
outstanding.

11.12 Severability.

     If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid
or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this
Agreement and the other Loan Documents shall not be affected or impaired thereby and (b) the
parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable
provisions with valid provisions the economic effect of which comes as close as possible to that of
the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular
jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

11.13 Replacement of Lenders.

     If (a) any Lender requests compensation under Section 3.04, (b) any Borrower is
required to pay any additional amount to any Lender or any Governmental Authority for the account
of any Lender pursuant to Sections 3.01, 3.02 or 3.04, (c) a Lender (a
“Non-Consenting Lender”) does not consent to a proposed change, waiver, discharge or
termination with respect to any Loan Document that has been approved by the Required Lenders as
provided in Section 11.01 but requires unanimous consent of all Lenders or all Lenders
directly affected thereby (as applicable) or (d) any Lender is a Defaulting Lender, then the
applicable Borrower may, at its sole expense and effort, upon notice to such Lender and the
applicable Administrative Agent, require such Lender to assign and delegate, without recourse (in
accordance with and subject to the restrictions contained in, and consents required by, Section
11.06), all of its interests, rights and obligations under this Agreement and the related Loan
Documents to an assignee that shall assume such obligations (which assignee may be another Lender,
if a Lender accepts such assignment), provided that:

     (i) the applicable Administrative Agent shall have received the assignment fee
specified in Section 11.06(b);

     (ii) such Lender shall have received payment of an amount equal to the outstanding
principal of its Loans and L/C Advances, accrued interest thereon, accrued fees and all
other amounts payable to it hereunder and under the other Loan Documents (including any
amounts under Section 3.05) from the assignee (to the extent of such outstanding
principal and accrued interest and fees) or the applicable Borrower (in the case of all
other amounts);

     (iii) in the case of any such assignment resulting from a claim for compensation under
Section 3.04 or payments required to be made pursuant to Section 3.01 or
3.02, such assignment will result in a reduction in such compensation or payments
thereafter;

     (iv) such assignment does not conflict with applicable Laws; and

109

 

     (v) in the case of any such assignment resulting from a Non-Consenting Lender’s failure
to consent to a proposed change, waiver, discharge or termination with respect to any Loan
Document, the applicable replacement bank, financial institution or Fund consents to the
proposed change, waiver, discharge or termination; provided that the failure by such
Non-Consenting Lender to execute and deliver an Assignment and Assumption shall not impair
the validity of the removal of such Non-Consenting Lender and the mandatory assignment of
such Non-Consenting Lender’s Commitments and outstanding Loans and participations in L/C
Obligations pursuant to this Section 11.13 shall nevertheless be effective without
the execution by such Non-Consenting Lender of an Assignment and Assumption.

     A Lender shall not be required to make any such assignment or delegation if, prior thereto, as
a result of a waiver by such Lender or otherwise, the circumstances entitling the applicable
Borrower to require such assignment and delegation cease to apply.

11.14 Governing Law; Jurisdiction; Etc.

     (a) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAW OF THE STATE OF NEW YORK (INCLUDING SECTION 5-1401 AND SECTION 5-1402 OF THE GENERAL
OBLIGATIONS LAW OF THE STATE OF NEW YORK) WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THAT WOULD
REQUIRE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION.

     (b) SUBMISSION TO JURISDICTION. EACH BORROWER AND EACH OTHER LOAN PARTY IRREVOCABLY
AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE
COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK CITY AND OF THE UNITED STATES DISTRICT COURT OF
THE SOUTHERN DISTRICT, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING

THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW
YORK STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE 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 OR IN ANY OTHER LOAN DOCUMENT SHALL AFFECT ANY
RIGHT THAT ANY ADMINISTRATIVE AGENT, ANY LENDER, OR ANY L/C ISSUER MAY OTHERWISE HAVE TO BRING ANY
ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AGAINST EMS OR ANY OTHER
LOAN PARTY OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

     (c) WAIVER OF VENUE. EACH BORROWER AND EACH OTHER LOAN PARTY IRREVOCABLY AND
UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT
MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT IN ANY COURT REFERRED TO IN PARAGRAPH (B) OF
THIS SECTION. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION
OR PROCEEDING IN ANY SUCH COURT.

110

 

     (d) SERVICE OF PROCESS. EACH PARTY HERETO IRREVOCABLY CONSENTS TO SERVICE OF PROCESS
IN THE MANNER PROVIDED FOR NOTICES IN SECTION 11.02. NOTHING IN THIS AGREEMENT WILL AFFECT
THE RIGHT OF ANY PARTY HERETO TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.

11.15 Waiver of Jury Trial.

     EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY
HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN
INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE
MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

11.16 No Advisory or Fiduciary Responsibility.

     In connection with all aspects of each transaction contemplated hereby (including in
connection with any amendment, waiver or other modification hereof or of any other Loan Document),
each Borrower acknowledges and agrees, and acknowledges its Affiliates’ understanding, that: (i)
(A) the arranging and other services regarding this Agreement provided by the Administrative Agents
and BAS, are arm’s-length commercial transactions between the Borrower and their Affiliates, on the
one hand, and the Administrative Agents and BAS, on the other hand, (B) the Borrowers have
consulted their own legal, accounting, regulatory and tax advisors to the extent each Borrower has
deemed appropriate, and (C) each Borrower is capable of evaluating, and understands and accepts,
the terms, risks and conditions of the transactions contemplated hereby and by the other Loan
Documents; (ii) (A) each Administrative Agent and BAS each is and has been acting solely as a
principal and, except as expressly agreed in writing by the relevant parties, has not been, is not
and will not be acting as an advisor, agent or fiduciary, for each Borrower or any of Affiliates or
any other Person and (B) neither any Administrative Agent nor BAS has any obligation to any
Borrower or any of its Affiliates with respect to the transactions contemplated hereby except those
obligations expressly set forth herein and in the other Loan Documents; and (iii) the
Administrative Agents and BAS and their respective Affiliates may be engaged in a broad range of
transactions that involve interests that differ from those of any Borrower and its Affiliates, and
neither any Administrative Agent nor BAS has any obligation to disclose any of such interests to
either Borrower or any of the Borrowers’ Affiliates. To the fullest extent permitted by law, each
Borrower hereby waives and releases, any claims that it may have against any Administrative Agent
or BAS with respect to any breach or alleged breach of agency or fiduciary duty in connection with
any aspect of any transaction contemplated hereby.

11.17 USA PATRIOT Act Notice.

     Each Lender that is subject to the Act (as hereinafter defined), the Domestic Administrative
Agent (for itself and not on behalf of any Lender) and the Canadian Administrative Agent (for
itself and not on behalf of any Lender) hereby notifies the Borrowers that pursuant to the
requirements of the USA

111

 

Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the
“Act”), it is required to obtain, verify and record information that identifies each
Borrower, which information includes the name and address of each Borrower and other information
that will allow such Lender, such Administrative Agent, as applicable, to identify such Borrower in
accordance with the Act. Each Borrower shall, promptly following a request by the applicable
Administrative Agent or any Domestic Lender or any Canadian Lender, as applicable, provide all
documentation and other information that such Administrative Agent or such Lender requests in order
to comply with its ongoing obligations under applicable “know your customer” and anti-money
laundering rules and regulations, including the Act.
