 Exhibit 10.5 
 RIG PERSONNEL SUPPLY AGREEMENT 
 This Rig
Personnel Supply Agreement (the “Agreement”) is made effective as of the              day of
                    , 2005 (the “Effective Date”), by and between Turnkey E&P Corporation a Nevada corporation
(“TEP”), and Tesco Corporation (US), a Delaware corporation (“Tesco US”). 
 RECITALS 
 A. TEP has acquired certain of the assets of Tesco US and of its parent, Tesco Corporation, relating to such companies’ contract Casing Drilling
services business (the “Business”). 
 B. Tesco US is a party to equipment leases (collectively, the “Lease Agreements”)
with Drillers Technology Corporation (“DTC”), whereby Tesco US agreed to lease three drilling rigs (collectively, the “Rigs”) from DTC, subject to the terms and conditions set forth in such Lease Agreements, which Tesco US will
use to provide drilling services to third parties. 
 C. In connection with the acquisition of the Business, TEP hired a number of the
employees of Tesco US who were responsible for managing the operation of the Rigs. 
 D. Since Tesco US no longer has sufficient staff to
manage the operation of the Rigs, it has requested that TEP provide sufficient personnel to enable Tesco US to fulfill its drilling services obligations to third party customers and TEP has agreed to provide necessary personnel to serve in such
capacity, subject to the terms and conditions set forth herein. 
 AGREEMENT 
 NOW, THEREFORE, in consideration of the premises and mutual covenants agreements contained in this Agreement, the parties
have agreed as follows:

third party customers, TEP shall provide personnel services with respect to the Rigs described on Exhibit A attached hereto and made a part hereof (collectively, the “Services”). 
 2. Term. The term of this Agreement shall be coterminous with the longest term of the Equipment Leases with DTC. If Tesco US wishes to renew or
extend the terms of one or more such Equipment Leases, it shall provide TEP with not less than 45 days prior written notice thereof and TEP shall advise Tesco US in writing within 15 days of its receipt of such notice, whether it has elected to
(i) terminate this Agreement at the end of the last initial term of the Lease Agreements, or (ii) extend the term of this Agreement, subject to the same terms and conditions, to coincide with the extended term or terms of the Lease
Agreements. Such 

 
determination shall be made by TEP in its sole discretion and, if it elects not to extend the term of this Agreement, it shall have no further obligations to
Tesco hereunder at the end of such term. 
 3. Compensation. The direct costs reimbursable to TEP and the overhead to be paid to TEP
for its performance of the Services shall be determined in accordance with Exhibit B attached hereto and made a part hereof. Such costs shall be invoiced by TEP every two weeks and Tesco US shall use its best efforts to pay such invoices as

locations designated by Tesco US and to operate the Rigs at such locations in accordance with the directions of Tesco US’ representatives, unless TEP reasonably believes that such directions will cause the well to be drilled in an imprudent or
unsafe manner, in which case TEP shall have the right to refuse to conduct the requested operation. 
 TEP shall maintain, at its expense,
the insurance described on Exhibit C attached hereto and made a part hereof and shall provide Tesco US with a certificate or certificates satisfactory to Tesco US that such insurance is in full force and effect, and that such insurance will

involving the Rigs, and of TEP personnel provided under this Agreement. Tesco US shall maintain, at its expense, the insurance described on Exhibit C attached hereto and made a part hereof and shall provide TEP with a certificate or

made to finance the reimbursement of an LC Disbursement as provided in Section 2.06(e), by remittance to the Issuing Bank) by 3:00 p.m., Local Time, on the requested date of such Swingline Loan. 
 (c) The Swingline Lender may by written notice given to the Administrative Agent not later than 10:00 a.m., Local Time, on any Business
Day require the Lenders to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which Lenders will participate. Any Swingline Loan
outstanding in Canadian Dollars shall, upon the giving of such notice by the Swingline Lender, immediately and automatically be converted to and redenominated in Dollars equal to the Dollar Equivalent thereof and shall bear interest at the greater
of the Alternate Base Rate or the rate otherwise applicable to such Swingline Loan. Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each Lender, specifying in such notice such Lender’s Applicable
Percentage of such Swingline Loan or Loans. Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, 

  

 22 

 
such Lender’s Applicable Percentage of such Swingline Loan or Loans. Each Lender acknowledges and agrees that its obligation to acquire participations
in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each
such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in
Section 2.07 with respect to Loans made by such Lender (and Section 2.07 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Swingline Lender the
amounts so received by it from the Lenders. The Administrative Agent shall notify the applicable Borrower of any participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan
shall be made to the Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from a Borrower (or other party on behalf of a Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of
the proceeds of a sale of participations therein shall be promptly remitted to the Administrative Agent; any such amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent to the Lenders that shall have made
their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear; provided that any such payment so remitted shall be repaid to the Swingline Lender or to the Administrative Agent, as applicable, if and to the
extent such payment is required to be refunded to a Borrower for any reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve any Borrower of any default in the payment thereof. 
 SECTION 2.06. Letters of Credit. (a) General. Subject to the terms and conditions set forth herein, the US Borrower may request the
issuance of Letters of Credit for its own account or the account of any LC Obligor, in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the Availability Period. In the event any
Letter of Credit is to be issued to any LC Obligor other than the US Borrower, such LC Obligor shall execute and deliver such letter of credit application or other agreement requested by the Issuing Bank and the US Borrower and such LC Obligor shall
be jointly and severally liable for all LC Exposure with respect to such Letter of Credit. Letters of Credit may be denominated in Dollars, Canadian Dollars or any other currency acceptable to the Administrative Agent that is freely available,
freely transferable and freely convertible into Dollars. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by
the any LC Obligor to, or entered into by the any LC Obligor with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control. 
 (b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the
amendment, renewal or extension of an outstanding Letter of Credit), the US Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank
and the Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended,
and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of
Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the Issuing Bank, the US Borrower and any other LC Obligor requesting
such Letter of Credit also shall submit a letter of credit application on the Issuing Bank’s standard form in connection with any request for a Letter of Credit or such other agreement reasonably requested by the Issuing Bank. A Letter of
Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the US 

  

 23 

 
Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension (i) the Dollar Equivalent
of the LC Exposure shall not exceed $15,000,000, (ii) the sum of the Dollar Equivalent of the total Revolving Credit Exposures shall not exceed the total Revolving Commitments and (iii) the Dollar Equivalent of the total Revolving Credit
Exposures shall not exceed the Borrowing Base. 
 (c) Expiration Date. Each Letter of Credit shall expire at or prior
to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that
is five Business Days prior to the Revolving Credit Maturity Date. 
 (d) Participations. By the issuance of a Letter
of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the
Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender
hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the US Borrower and
other applicable LC Obligors on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the US Borrower or any other applicable LC Obligor for any reason. Each Lender acknowledges
and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension
of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. 
 (e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the US Borrower and each
other applicable LC Obligor shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, Chicago time, on the date that such LC Disbursement is made, if the US Borrower
shall have received notice of such LC Disbursement prior to 10:00 a.m., Chicago time, on such date, or, if such notice has not been received by the US Borrower prior to such time on such date, then not later than 12:00 noon, Chicago time, on
(i) the Business Day that the US Borrower receives such notice, if such notice is received prior to 10:00 a.m., Chicago time, on the day of receipt, or (ii) the Business Day immediately following the day that the US Borrower receives such
notice, if such notice is not received prior to such time on the day of receipt; provided that the US Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.03 or 2.05 that such
payment be financed with an ABR Revolving Borrowing or Swingline Loan in an equivalent amount and, to the extent so financed, the US Borrower’s and any other applicable LC Obligor’s obligation to make such payment shall be discharged and
replaced by the resulting ABR Revolving Borrowing or Swingline Loan. If any LC Obligor fails to make such payment when due, (x) such payment obligation outstanding in any currency other than Dollars shall be immediately and automatically
converted to and redenominated in Dollars equal to the Dollar Equivalent thereof and shall bear interest at the Alternate Base Rate and (y) the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then
due from any LC Obligor in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from any
LC Obligor, in the same manner as provided in Section 2.07 with respect to Loans made by such Lender (and Section 2.07 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent
shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment 

  

 24 

 
from any LC Obligor pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders
have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing Bank for any LC
Disbursement (other than the funding of ABR Revolving Loans or a Swingline Loan as contemplated above) shall not constitute a Loan and shall not relieve any LC Obligor of its obligation to reimburse such LC Disbursement. 
 (f) Obligations Absolute. Each LC Obligor’s obligation to reimburse LC Disbursements as provided in paragraph (e) of this
Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability
of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or
inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance
whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, any LC Obligor’s obligations hereunder. Neither
the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to
make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or
relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the
foregoing shall not be construed to excuse the Issuing Bank from liability to any LC Obligor to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by each LC Obligor to the extent
permitted by applicable law) suffered by any LC Obligor that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The
parties hereto expressly agree that, in the absence of gross negligence or wilful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction or mutually agreed upon by the Issuing Bank and all other
parties), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on
their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any
notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit. 
 (g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to
represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the US Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or
will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve any LC Obligor of its obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC
Disbursement. 
  

 25 

 (h) Interim Interest. If the Issuing Bank shall make any LC Disbursement,
then, unless such LC Disbursement has been paid in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date such LC
Disbursement is reimbursed in full, at the rate per annum then applicable to ABR Revolving Loans; provided that, if any LC Obligor fails to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then
Section 2.13(c) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section to
reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment. 
 (i) Replacement of the
Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the US Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any
such replacement of the Issuing Bank. At the time any such replacement shall become effective, the US Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.12(b). From and after the
effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein
to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder,
the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be
required to issue additional Letters of Credit. 
 (j) Cash Collateralization. If any Event of Default shall occur and
be continuing, on the Business Day that the US Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure representing greater than 50% of the total
LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, the US Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in
cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and
payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the US Borrower described in clause (h) or (i) of Article VII. Such deposit shall be held by the Administrative Agent as
collateral for the payment and performance of the obligations of the LC Obligors under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any
interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the US Borrower’s risk and expense, such deposits shall not bear interest. Interest or
profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not
so applied, shall be held for the satisfaction of the reimbursement obligations of the LC Obligors for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure
representing greater than 50% of the total LC Exposure), be applied to satisfy other obligations of the Borrowers under this Agreement. If the US Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of
an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the US Borrower within three Business Days after all Events of Default have been cured or waived. 
 SECTION 2.07. Funding of Borrowings. (a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire
transfer of immediately available funds by 12:00 noon, Chicago time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders; provided that Swingline Loans shall be made as provided
in 

  

 26 

 
Section 2.05. The Administrative Agent will make such Loans available to the US Borrower by promptly crediting the amounts so received, in like funds,
to an account of the US Borrower maintained with the Administrative Agent and designated by the US Borrower in the applicable Borrowing Request or in such other manner as agreed upon between the Administrative Agent and the US Borrower;
provided that ABR Revolving Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.06(e) shall be remitted by the Administrative Agent to the Issuing Bank. 
 (b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender
will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and
may, in reliance upon such assumption, make available to the US Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender
and the US Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the US Borrower to but excluding
the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank
compensation or (ii) in the case of the US Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

 SECTION 2.08. Interest Elections. (a) Each Borrowing initially shall be of the Type specified in the applicable Borrowing
Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the US Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and,
in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. The US Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion
shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. This Section shall not apply to Swingline Borrowings, which may not be
converted or continued. 
 (b) To make an election pursuant to this Section, the US Borrower shall notify the Administrative
Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the US Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such
election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative
Agent and signed by the US Borrower. 
 (c) Each telephonic and written Interest Election Request shall specify the following
information in compliance with Section 2.02: 
 (i) the Borrowing to which such Interest Election Request applies and, if
different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall
be specified for each resulting Borrowing); 
 (ii) the effective date of the election made pursuant to such Interest Election
Request, which shall be a Business Day; 
  

 27 

 (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar
Borrowing; and 
 (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto
after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”. 
 If any such Interest
Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the US Borrower shall be deemed to have selected an Interest Period of one month’s duration. 
 (d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof
and of such Lender’s portion of each resulting Borrowing. 
 (e) If the US Borrower fails to deliver a timely Interest
Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an
ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the US Borrower, then, so long as an Event of
Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period
applicable thereto. 
 SECTION 2.09. Termination and Reduction of Commitments. (a) Unless previously terminated, the Commitments
shall terminate on the Revolving Credit Maturity Date. 
 (b) The US Borrower may at any time terminate, or from time to
time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000 and (ii) the US Borrower shall not terminate or reduce
the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.11, the Revolving Credit Exposures would exceed the total Revolving Commitments. 
 (c) The US Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b)
of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the
Lenders of the contents thereof. Each notice delivered by the US Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by the US Borrower may state that such notice is
conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the US Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any
termination or reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments. 
 SECTION 2.10. Repayment of Loans. (a) The US Borrower hereby unconditionally promises to pay to the Administrative Agent for the account
of each Lender the then unpaid principal amount of each Revolving Loan on the Revolving Credit Maturity Date. The Borrowers hereby unconditionally promise to pay to the Swingline Lender the then unpaid principal amount of each Swingline Loan on the
earlier of the Revolving Credit Maturity Date or the demand by the Swingline Lender in its discretion. 
  

 28 

 (b) If at any time the Dollar Equivalent of the aggregate Revolving Credit Exposure of
all Lenders exceeds (i) the total Revolving Commitments or (ii) the Borrowing Base, the Borrowers shall promptly repay such excess. If any such excess remains after repayment in full of all outstanding Revolving Loans and Swingline Loans,
the US Borrower shall provide cash collateral for the LC Exposure in the manner set forth herein to the extent required to eliminate such excess. 
 (c) The US Borrower shall pay the Term Loans in sixteen (16) consecutive quarterly principal installments, each in the amount of $3,125,000 and each payable on the last Business Day of each January, April, July
and October, commencing on the last Business Day of January, 2007, and with the last such installment due on the Term Loan Maturity Date. 
 (d) In addition to all other payments of the Term Loans required hereunder, unless the Leverage Ratio was less than 1.0 to 1.0 as of the most recently ended Fiscal Quarter prior to such sale, the US Borrower shall
prepay the Term Loans by an amount equal to 50% of all of the Net Cash Proceeds from any Asset Sale or Event of Loss, provided that: 
 (i) With respect to Net Cash Proceeds from the sale of any rental fleet assets and other plant, property, and equipment assets, such Net Cash Proceeds may be used to purchase similar rental fleet assets and other plant, property, and
equipment assets of comparable value, subject to the following conditions: (x) no Default exists on the date of such sale or of the proposed expenditure to purchase similar rental fleet assets and other plant, property, and equipment assets of
comparable value, (y) such Net Cash Proceeds shall be used to purchase similar rental fleet assets and other plant, property, and equipment assets of comparable value within 270 days following the date of such sale and (z) any such amounts
in excess of $5,000,000 in the aggregate in any Fiscal Year shall be deposited in escrow with the Administrative Agent, to be paid out when such similar rental fleet assets and other plant, property, and equipment assets of comparable value are
purchased; provided that, if any of the foregoing conditions are not satisfied at any time then all such Net Cash Proceeds, whether held in escrow, held by the Borrowers or otherwise, shall then used to prepay the Term Loans by the amount thereof.

 (ii) With respect to Net Cash Proceeds from insurance paid with respect to any Event of Loss, such Net Cash Proceeds may
used to replace, rebuild or repair the assets for which such Net Cash Proceeds were paid, subject to the following conditions: (x) no Default exists on the date of such Event of Loss or of the proposed expenditure to replace, rebuild or repair,
(y) the Parent delivers a certificate to Administrative Agent within 10 Business Days of such Event of Loss stating that such Net Cash Proceeds shall be used to replace, rebuild or repair such assets or other capital assets used or useful in
the Borrowers’ business within 270 days following the date of such Event of Loss (which certificate shall set forth the estimates of the proceeds to be so expended and when they will be expended) and such replacement, rebuilding or repair is
completed within 365 days following the date of such Event of Loss, and (z) any such amounts in excess of $5,000,000 in the aggregate in any Fiscal Year shall be deposited in escrow with Administrative Agent, to be paid out from time to time as
work progresses based on such documents and other conditions as the Administrative Agent may reasonably require; provided that, if any of the foregoing conditions are not satisfied at any time then all such Net Cash Proceeds, whether held in escrow,
held by the Borrower or otherwise, shall then used to prepay the Term Loans by the amount thereof. 
 (e) In addition to all
other payments of the Term Loans required hereunder, the US Borrower shall prepay the Term Loans by an amount equal to 50% of the Net Cash Proceeds from the issuance or other sale of any Equity Interests of the Parent or any of its Subsidiaries in
excess of 

  

 29 

 
$10,000,000 after the Effective Date, other than (i) such Net Cash Proceeds used exclusively for Acquisitions permitted hereunder and (ii) Net Cash
Proceeds as a result of the purchase of any Equity Interests of the Parent by employees, officers or directors of the Parent or its Subsidiaries that are not material. 
 (f) In addition to all other payments of the Term Loans required hereunder, the US Borrower shall prepay the Term Loans by an amount equal
to 50% of the Net Cash Proceeds of any Subordinated Indebtedness incurred by the Parent or any of its Subsidiaries. 
 (g) All
prepayments of the Term Loans (whether mandatory under this Section 2.10 or optional under Section 2.11) up to $13,000,000 in aggregate amount shall be applied to principal installments on the Term Loans in the inverse order of maturity
and all such prepayments in excess of $13,000,000 in aggregate amount shall be applied pro rata to all principal installments on the Term Loans. 
 SECTION 2.11. Prepayment of Loans. (a) The Borrowers shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with paragraph (b) of this
Section. 
 (b) The Borrowers shall notify the Administrative Agent (and, in the case of prepayment of a Swingline Loan, the
Swingline Lender) by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than noon, Chicago time, three Business Days before the date of prepayment, (ii) in the
case of prepayment of an ABR Borrowing, not later than noon, Chicago time, one Business Day before the date of prepayment or (iii) in the case of prepayment of a Swingline Loan, not later than 12:00 noon, Toronto time, on the date of prepayment
or such other time agreed to between the applicable Borrower and the Swingline Lender. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid;
provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.09, then such notice of prepayment may be revoked if such notice of termination is
revoked in accordance with Section 2.09. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an
amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be
accompanied by accrued interest to the extent required by Section 2.13. 
 SECTION 2.12. Fees. (a) The Borrowers agree to
pay to the Administrative Agent for the account of each Lender an unused commitment fee at a per annum rate equal to the Applicable Rate (i) on the average daily amount by which each such Lender’s Revolving Commitment exceeds the
outstanding principal amount of such Lender’s Revolving Loans and its LC Exposure, during the period from and including the Effective Date to but excluding the date on which such Revolving Commitment terminates and (ii) on the average
daily amount by which each such Lender’s Term Loan Commitments exceeds the outstanding principal amount of such Lender’s Term Loans, during the period from and including the Effective Date to but excluding the earlier of the date on which
the Term Loans are made or November 30, 2005. Swingline Loans shall not count as usage of the Revolving Commitment of any Lender’s Revolving Commitment for purposes of determining such commitment fees. Accrued commitment fees shall be
payable in arrears on third Business Day after the last day of March, June, September and December of each year and on the date on which the any applicable Commitment terminates, commencing on the first such date to occur after the date hereof. All
commitment fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). 
  

 30 

 (b) The Borrowers agree to pay (i) to the Administrative Agent for the account of
each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Rate used to determine the interest rate applicable to Eurodollar Revolving Loans on the average daily amount of such
Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates
and the date on which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of the LC Exposure (excluding any portion thereof
attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, provided that
such fee shall not be less than $200, as well as the Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees
accrued through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the Effective Date; provided
that all such fees shall be payable on the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this
paragraph shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding
the last day). 
 (c) The Borrowers agree to pay to the Administrative Agent, for its own account, fees payable in the
amounts and at the times separately agreed upon between any Borrower and the Administrative Agent. 
 (d) All fees payable
hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of commitment fees and participation fees, to the
Lenders. Once paid, fees shall not be refundable under any circumstances. 
 SECTION 2.13. Interest. (a) The Loans comprising
each ABR Borrowing (including each Swingline Loan) shall bear interest at the Alternate Base Rate. 
 (b) The Loans
comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate. 
 (c) Notwithstanding the foregoing, during the continuance of an Event of Default the Required Lenders may, at their option, by notice to
the Borrowers (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 9.02 requiring unanimous consent of the Lenders to changes in interest rates), declare that (i) each Eurodollar Loan
shall bear interest for the remainder of the applicable Interest Period at the rate otherwise applicable to such Interest Period plus 2% per annum, (ii) the rate of each participation fee payable under Section 2.12(b)(i) with respect
to Letters of Credit shall be increased by 2% per annum and (iii) each ABR Loan shall bear interest at a rate per annum equal to the Alternate Base Rate in effect from time to time plus 2% per annum, provided that, during the
continuance of an Event of Default under clause (h) or (i) of Article VII, the rates set forth in clauses (i), (ii) and (iii) above shall be applicable to all Loans and Letters of Credit without any election or action on the part
of the Administrative Agent or any Lender. 
  

 31 

 (d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment
Date for such Loan and, in the case of Revolving Loans, upon termination of the Commitments; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any
repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving Loan prior to the end of the Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or
prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion. 
 (e) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the
Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed
(including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error. 

(f) For the purposes of the Interest Act (Canada) hereunder (i) whenever interest payable pursuant to this Agreement is
calculated with respect to any monetary obligation relating to Loans to the Canadian Borrower on the basis of a period other than a calendar year (the “Calculation Period”), each rate of interest determined pursuant to such
calculation expressed as an annual rate is equivalent to such rate as so determined, multiplied by the actual number of days in the calendar year in which the same is to be ascertained and divided by the number of days in the Calculation
Period; (ii) the principle of deemed reinvestment of interest with respect to any monetary obligation relating to Loans in Canadian Dollars shall not apply to any interest calculation under this agreement, and (iii) the rates of interest
with respect to any monetary obligation relating to Loans to the Canadian Borrower stipulated in this Agreement are intended to be nominal rates and not effective rates or yields. 
 SECTION 2.14. Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing: 
 (a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means
do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or 
 (b) the
Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their
Loans (or its Loan) included in such Borrowing for such Interest Period; 
 then the Administrative Agent shall give notice thereof to the US Borrower and
the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the US Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election
Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an
ABR Borrowing; provided that if the circumstances giving rise to such notice affect only one Type of Borrowings, then the other Type of Borrowings shall be permitted. 
  

 32 

 SECTION 2.15. Increased Costs. (a) If any Change in Law shall: 
 (i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the
account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or the Issuing Bank; or 
 (ii) impose on any Lender or the Issuing Bank or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or 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 Loan (or of maintaining its
obligation to make any such Loan) or to increase the cost to such Lender or the Issuing Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or the Issuing
Bank hereunder (whether of principal, interest or otherwise), then the US Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank, as the case may
be, for such additional costs incurred or reduction suffered. 
 (b) If any Lender or the Issuing Bank determines that
any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company,
if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such
Lender’s or the Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing
Bank’s holding company with respect to capital adequacy), then from time to time the Borrowers will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank
or such Lender’s or the Issuing Bank’s holding company for any such reduction suffered. 
 (c) A certificate of
a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to
the Borrowers and shall be conclusive absent manifest error. The Borrowers shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof. 
 (d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not
constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the Borrowers shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased
costs or reductions incurred more than 180 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrowers of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or
the Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to
include the period of retroactive effect thereof. 
 SECTION 2.16. Break Funding Payments. In the event of (a) the payment of any
principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period
applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(b) and is
revoked in accordance therewith), or (d) the 

  

 33 

 
assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the US Borrower pursuant
to Section 2.19, then, in any such event, the US Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to
include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been
applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period
for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a
comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth the amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the US Borrower and shall
be conclusive absent manifest error. The US Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 
 SECTION 2.17. Taxes. (a) Any and all payments by or on account of any obligation of the Borrowers hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other
Taxes; provided that if the Borrowers shall be required to deduct any Indemnified Taxes or 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) the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the
Borrowers shall make such deductions and (iii) the Borrowers shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. 
 (b) In addition, the Borrowers shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

 (c) The Borrowers shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within 10 days after
written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the
Borrowers hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) 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 setting forth the amount of such payment or liability delivered to the Borrowers by a Lender or the Issuing
Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error. 
 (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrowers to a Governmental Authority, the Borrowers shall deliver to the 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 Administrative Agent. 
 (e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in
which the US Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the US Borrower (with a copy to the Administrative Agent), at the time or times prescribed by
applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by 

  

 34 

 
the US Borrower as will permit such payments to be made without withholding or at a reduced rate. In addition, any Foreign Lender, if requested by the US
Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine
whether or not such Lender is subject to backup withholding or information reporting requirements. 
 (f) If the
Administrative Agent or a Lender determines that it has received a refund or credit of any Taxes or Other Taxes as to which it has been indemnified by the Borrowers or with respect to which the Borrowers has paid additional amounts pursuant to this
Section 2.17, it shall pay over such refund to the Borrowers (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrowers under this Section 2.17 with respect to the Taxes or Other Taxes giving rise to
such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Borrowers, upon the
request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrowers (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in
the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other
information relating to its taxes which it deems confidential) to the Borrowers or any other Person. 
 (g) If JPMorgan Chase
Bank, N.A., Toronto Branch shall not be a Canadian Lender at any time after the Effective Date, then JPMorgan Chase Bank, N.A., Toronto Branch shall use reasonable efforts to designate a different lending office for funding or booking the Swingline
Canadian Loans hereunder or issuing Letters of Credit for the account of any Canadian LC Obligor or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates that is a Canadian Lender or, if no such office,
branch or Affiliate exists and no Default exists, use reasonable efforts to assign its functions as the Issuing Bank for Letters of Credit to any Canadian LC Obligor and as the Swingline Lender to the Canadian Borrower to a lender that is either a
Canadian Lender or would, upon taking such an assignment, be a Canadian Lender. The Borrowers hereby agree to pay all costs and expenses incurred by the Administrative Agent, JPMorgan Chase Bank, N.A., Toronto Branch, any of its Affiliates or any
Lender in connection with any such designation or assignment. All parties hereto agree to execute such agreements as reasonably requested by the Administrative Agent to effect such designation or assignment. 
 SECTION 2.18. Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) The Borrowers shall make each payment required to be made by
it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursement) by noon Local Time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may,
in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices designated to
the Borrowers from time to time, except payments to be made directly to the Issuing Bank or Swingline Lender as expressly provided herein and except that payments pursuant to Sections 2.15, 2.16, 2.17 and 9.03 shall be made directly to the Persons
entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is
not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be
made in dollars. 
  

 35 

 (b) If at any time insufficient funds are received by and available to the Administrative
Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment 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 (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance
with the amounts of principal and unreimbursed LC Disbursements then due to such parties. 
 (c) If any Lender shall, by
exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Revolving Loans, Term Loans or participations in LC Disbursements or Swingline Loans resulting in such Lender
receiving payment of a greater proportion of the aggregate amount of its Revolving Loans, Term Loans and participations in LC Disbursements and Swingline Loans and accrued interest thereon than the proportion received by any other Lender, then the
Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Revolving Loans, Term Loans and participations in LC Disbursements and Swingline Loans of other Lenders to the extent necessary so that the
benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Revolving Loans, Term Loans and participations in LC Disbursements and Swingline
Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such
recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrowers pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a
Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Parent or any Subsidiary or Affiliate thereof (as to which the
provisions of this paragraph shall apply). The Borrowers consent 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 the Borrowers rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrowers in the amount of such participation. 
 (d) Unless the Administrative Agent shall have received notice from the Borrowers prior to the date on which any payment is due to the
Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrowers will not make such payment, the Administrative Agent may assume that the Borrowers have made such payment on such date in accordance herewith and
may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if a Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may
be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank 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 Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. 
 (e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(c), 2.06(d) or (e), 2.07(b),
2.18(d) or 9.03(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s
obligations under such Sections until all such unsatisfied obligations are fully paid. 
  

 36 

 (f) All proceeds of any realization on the Collateral pursuant to the Collateral
Documents and any payments received by the Administrative Agent or any Lender subsequent to and during the continuance of any Event of Default, subject to the obligations secured thereby, shall be allocated and distributed by the Agent as follows:

 (i) First, to the payment of all fees, costs, expenses and other amounts owing to the Administrative Agent, including
without limitation all reasonable attorneys’ fees, in connection with the enforcement of the Collateral Documents and otherwise administering the Loan Documents; 
 (ii) Second, to payment of any Secured Obligations pro rata among those parties to whom such Secured Obligations are due in accordance
with the amounts owing to each of them, provided that the proceeds of any realization on the Collateral may be altered by the Administrative Agent, with the consent of the Lenders, in a manner to maximize the recovery by all Lenders and their
Affiliates and which would not decrease the recovery of any Lender; and 
 (iii) Third, to the Borrowers, their Subsidiaries
or such other Person as may be legally entitled thereto 
 The order and priority set forth in this Section 2.18(f) and the related provisions are set
forth solely to determine the rights and priorities of the Administrative Agent and the Lenders as among themselves, and the order and priority may at any time be changed by the Lenders without the consent of the Borrowers, provided that the order
or priority of any payment to the Administrative Agent may only be changed with the consent of the Administrative Agent. 
 SECTION 2.19.
Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.15, 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 Section 2.17, then such Lender shall 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, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.15 or 2.17, as the case may be, in the future and (ii) would not
subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrowers hereby agree to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or
assignment. 
 (b) If any Lender requests compensation under Section 2.15, 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 Section 2.17, or if any Lender is a Defaulting Lender, then such Borrower may, at its sole expense and effort, upon notice to such Lender
and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to an
assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) such Borrower shall have received the prior written consent of the Administrative Agent (and if a
Commitment is being assigned, the Issuing Bank), which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements
and Swingline Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or such Borrower (in the case of all other
amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such compensation
or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling such Borrower to require such assignment and delegation cease
to apply. 
  

 37 

 ARTICLE III 
 Representations and Warranties 
 In order to induce the Lenders and the Administrative Agent to enter
into this Agreement, each Borrower represents and warrants to each Lender and the Administrative Agent, that the following statements are true, correct and complete (it being understood and agreed that the representations and warranties made on the

delivered by each Borrower and constitutes a legal, valid and binding obligation of each Borrower, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other
laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

 SECTION 3.05. Properties. (a) Each of the Parent and its Subsidiaries has good title to, or
valid leasehold interests in, all its real and personal property material to its business, except for minor defects in title that do not interfere with its ability to conduct its business as currently conducted or to utilize such properties for
their intended purposes, and all such real and personal property is free and clear of any Lien except for Liens permitted under Section 6.02. Each Collateral Document is effective to create in favor of the Administrative Agent a legal, valid,
perfected and enforceable security interest in the Collateral. 
 (b) Each of the Parent and its Subsidiaries owns, or is
licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual property material to its business, and the use thereof by the Parent and its Subsidiaries does not infringe upon the rights of any other Person, except for any
such infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. 
 SECTION 3.06. Litigation and Environmental Matters. (a) There are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of the Parent, threatened against or
affecting the Parent or any of its Subsidiaries (i) as to which there is a reasonable possibility of an adverse determination and that, if adversely determined, could reasonably be expected, individually or in the aggregate, to result in a
Material Adverse Effect or (ii) that involve this Agreement or the Transactions. The Disclosed Matters could not reasonably be expected to result in a Material Adverse Effect. 
 (b) Except for the Disclosed Matters and except with respect to any other matters that, individually or in the aggregate, could not

agreements and other instruments binding upon it or its property, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. No Default has occurred and is

 SECTION 3.10. Pension Plans. No ERISA Event has occurred or is reasonably expected to occur that,
when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect. The present value of all accumulated benefit obligations under each Plan
(based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed by more than $1,000,000 the fair market value of
the assets of such Plan, and the present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the
most recent financial statements reflecting such amounts, exceed by more than $1,000,000 the fair market value of the assets of all such underfunded Plans. No Borrower or Subsidiary has a material contingent liability with respect to any
post-retirement benefit under a Canadian Welfare Plan. With respect to Canadian Pension Plans: (a) no steps have been taken to terminate any Canadian Pension Plan (wholly or in part) which could result in any Borrower or Subsidiary being
required to make an additional contribution to the Canadian Pension Plan; (b) no contribution failure has occurred with respect to any Canadian Pension Plan sufficient to give rise to a lien or charge under any applicable pension benefits laws
of any other jurisdiction; and (c) no condition exists and no event or transaction has occurred with respect to any Canadian Pension Plan which is reasonably likely to result in any Borrower or Subsidiary incurring any material liability, fine
or penalty. Each Canadian Pension Plan is in compliance in all material respects with all applicable pension benefits and tax laws; (i) all contributions (including employee contributions made by authorized payroll deductions or other
withholdings) required to be made to the appropriate funding agency in accordance with all applicable laws and the terms of each pension plan have been made in accordance with all applicable laws and the terms of each Canadian Pension Plan;
(ii) all liabilities under each Canadian Pension Plan are funded, on a going concern and solvency basis, in accordance with the terms of the respective Canadian Pension Plans, the requirements of applicable pension benefits laws and of
applicable regulatory authorities and the most recent actuarial report filed with respect to the Canadian Pension Plan and there is no accumulated funding deficit with respect to any Canadian Pension Plan; and (iii) no event has occurred and no
conditions exist with respect to any Canadian Pension Plan that has resulted or could reasonably be expected to result in any Canadian Pension Plan having its registration revoked or refused by any administration of any relevant pension benefits
regulatory authority or being required to pay any taxes or penalties under any applicable pension benefits or tax laws. 
 SECTION 3.11.
Disclosure. The Parent has disclosed to the Lenders all agreements, instruments and corporate or other restrictions to which it or any of its Subsidiaries is subject, and all other matters known to it, that, individually or in the aggregate,

the negotiation of this Agreement or delivered hereunder (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 projected financial information, the Parent represents only that such financial information was prepared in good faith based upon
assumptions believed to be reasonable at the time such projections were made.

substantially all costs and expenses in connection with the Alpha Acquisition are described in the flow of funds memo delivered to the Administrative Agent prior to the Alpha Acquisition Date. Upon the closing of the Alpha Acquisition, the US
Borrower shall have a first priority, enforceable and perfected security interest in all assets and Equity Interests of each SPV in connection with the Alpha Acquisition, including with limitation all Replacement Assets owned by each such SPV, which
will be collaterally assigned to the Administrative Agent under the Collateral Documents. All representations in the Alpha Acquisition Certificate are true and correct in all material respects. To the Parent’s knowledge, since June 30,
2005 there has been no material adverse change in the business, property, prospects, condition (financial or otherwise) or results of operations of either Alpha and its Subsidiaries taken as a whole. 
 SECTION 3.13. Omega Acquisition. All agreements and documents to be executed or delivered in connection with the Omega Acquisition are listed on
Schedule 3.13 hereof (the “Omega Acquisition Documents”). Simultaneously with the making of the Omega Term Loans hereunder, the Omega Acquisition shall be closed in accordance with the Omega Acquisition Documents and in

Acquisition, the US Borrower shall have a first priority, enforceable and perfected security interest in all assets and Equity Interests of each SPV in connection with the Omega Acquisition, including with limitation all Replacement Assets owned by
each such SPV, which will be collaterally assigned to the Administrative Agent under the Collateral Documents. All representations in the Omega Acquisition Certificate are true and correct in all material respects. To the Parent’s knowledge,
since June 30, 2005 there has been no material adverse change in the business, property, prospects, condition (financial or otherwise) or results of operations of either Omega and its Subsidiaries taken as a whole. 
 SECTION 3.14. Labor Matters. Except as would not reasonably be expected to have a Material Adverse Effect , (a) there are no strikes,
lockouts or slowdowns against the Parent or any Subsidiary pending or, to the knowledge of the Borrowers, threatened, (b) the hours worked by and payments made to employees of the Borrower and the Subsidiaries have not been in violation of the
Fair Labor Standards Act or any other applicable Federal, state, local or foreign law dealing with such matters, and (c) all payments due from the Parent or any Subsidiary, or for which any claim may be made against the Parent or any
Subsidiary, on account of wages and employee health and welfare insurance and other benefits, have been paid or accrued as a liability on the books of the Parent or such Subsidiary. The consummation of the Transactions will not give rise to any
right of termination or right of renegotiation on the part of any union under any collective bargaining agreement to which the Parent or any Subsidiary is bound. 
  

 41 

 SECTION 3.15. Solvency. (a) the fair value of the assets of each Loan Party, at a fair
valuation, will exceed its debts and liabilities, subordinated, contingent or otherwise; (b) the present fair saleable value of the property of each Loan Party will be greater than the amount that will be required to pay the probable liability

 ARTICLE VIII 
 The Administrative Agent 
 Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to
take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto. 
 The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may
exercise the same as though it were not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Parent or any Subsidiary or other Affiliate thereof as
if it were not the Administrative Agent hereunder. 
 The Administrative Agent shall not have any duties or obligations except those
expressly set forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing,
(b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to
exercise in writing as directed by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except as expressly set forth herein, the
Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Parent or any of its Subsidiaries that is communicated to or obtained by the bank serving as
Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the
Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or wilful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and
until written notice thereof is given to the Administrative Agent by the Borrowers or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or
representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants,
agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth
in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. 
 The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to
have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by 

  

 58 

 
it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may
be counsel for the Borrowers), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 
 The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the
Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply
to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities
as Administrative Agent. 
 Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the
Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrowers. Upon any such resignation, the Required Lenders shall have the right to appoint a successor. If no successor shall have been so appointed by
the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank,
appoint a successor Administrative Agent. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrowers to a successor Administrative Agent shall be the same as those payable to its predecessor
unless otherwise agreed between the Borrowers and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 9.03 shall continue in effect for the benefit of such retiring
Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent. 
 Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender 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 also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender
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 related agreement or any document furnished
hereunder or thereunder. 
 The Administrative Agent shall have no obligation whatsoever to any of the Lenders to assure that the Collateral
exists or is owned by the Loan Parties or is cared for, protected, or insured or has been encumbered, or that the Liens granted to the Administrative Agent therein have been properly or sufficiently or lawfully created, perfected, protected, or
enforced or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to
the Administrative Agent pursuant to any of the Loan Documents, it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Administrative Agent may act in any manner it may deem appropriate,
in its sole discretion given the Administrative Agent’s own interest in the Collateral in its capacity as one of the Lenders and that the Administrative Agent shall have no other duty or liability whatsoever to any Lender as to any of the
foregoing. 
 Each Lender hereby appoints each other Lender as its agent for the purpose of perfecting Liens, for the benefit of the
Administrative Agent and the Lenders, in assets which, in accordance with 

  

 59 

 
Article 9 of the UCC or any other applicable law can be perfected only by possession. Should any Lender (other than the Administrative Agent) obtain
possession of any such Collateral, such Lender shall notify the Administrative Agent thereof, and, promptly upon the Administrative Agent’s request therefor shall deliver such Collateral to the Administrative Agent or otherwise deal with such
Collateral in accordance with the Administrative Agent’s instructions. 
 Each Lender hereby agrees as follows: (a) such Lender is
deemed to have requested that the Administrative Agent furnish such Lender, promptly after it becomes available, a copy of each Report prepared by or on behalf of the Administrative Agent; (b) such Lender expressly agrees and acknowledges that
neither the Administrative Agent nor any Related Party (i) makes any representation or warranty, express or implied, as to the completeness or accuracy of any Report or any of the information contained therein, or (ii) shall be liable for
any information contained in any Report; (c) such Lender expressly agrees and acknowledges that the Reports are not comprehensive audits or examinations, that the Administrative Agent, any of its Related Parties or any other party performing
any audit or examination will inspect only specific information regarding the Loan Parties and will rely significantly upon the Loan Parties’ books and records, as well as on representations of the Loan Parties’ personnel and that the
Administrative Agent and its Related Parties undertake no obligation to update, correct or supplement the Reports; (d) such Lender agrees to keep all Reports confidential and strictly for its internal use, not share the Report with any Loan
Party and not to distribute any Report to any other Person except as otherwise permitted pursuant to this Agreement; and (e) without limiting the generality of any other indemnification provision contained in this Agreement, such Lender agrees
(i) that neither the Administrative Agent nor any of its Related Parties shall be liable to such Lender or any other Person receiving a copy of the Report for any inaccuracy or omission contained in or relating to a Report, (ii) to conduct
its own due diligence investigation and make credit decisions with respect to the Loan Parties based on such documents as such Lender deems appropriate without any reliance on the Reports or on the Administrative Agent or any of its Related Parties,
(iii) to hold the Administrative Agent and any such other Person preparing a Report harmless from any action the indemnifying Lender may take or conclusion the indemnifying Lender may reach or draw from any Report in connection with any Credit
Extensions that the indemnifying Lender has made or may make to the Loan Parties, or the indemnifying Lender’s participation in, or the indemnifying Lender’s purchase of, any Obligations and (iv) to pay and protect, and indemnify,
defend, and hold the Administrative Agent and any such other Person preparing a Report harmless from and against, the claims, actions, proceedings, damages, costs, expenses, and other amounts (including reasonable attorney fees) incurred by the
Administrative Agent and any such other Person preparing a Report as the direct or indirect result of any third parties who might obtain all or part of any Report through the indemnifying Lender. 
 The Lenders hereby empower and authorize the Administrative Agent to execute and deliver to the Loan Parties on their behalf the Collateral Documents and
all related agreements, documents or instruments as shall be necessary or appropriate to effect the purposes of the Collateral Documents. 
 The Lenders hereby empower and authorize the Administrative Agent to execute and deliver to the Loan Parties on their behalf any agreements, documents or instruments as shall be necessary or appropriate to effect any releases or
subordinations of Collateral which shall be permitted by the terms hereof or of any other Loan Document (whether pursuant to a permitted sale or otherwise) or which shall otherwise have been approved by the Required Lenders in writing.

 (b) Notices and other communications to the Lenders hereunder may be delivered or furnished by electronic communications
pursuant to procedures approved by the Administrative Agent; provided that the foregoing shall not apply to notices pursuant to Article II unless otherwise agreed by the Administrative Agent and the applicable Lender. The Administrative Agent or a
Borrower 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

 (c) Any party hereto may change its address or telecopy number for notices and other communications
hereunder by notice to the other parties hereto. All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt. 
 SECTION 9.02. Waivers; Amendments. (a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any
right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise
thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No
waiver of any provision of this Agreement or consent to any departure by the Borrowers therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of
whether the Administrative Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time. 
 (b) Neither
this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrowers and the Required Lenders or by the Borrowers and the Administrative Agent with the
consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender or increase the aggregate amount of all Commitments, (ii) reduce the 

  

 61 

 
principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of
each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such
payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.18(b) or (c) in a manner that would alter the pro rata sharing of payments
required thereby, without the written consent of each Lender, (v) release all or substantially all of the Collateral without the written consent of each Lender, (vi) release the Guarantor without the written consent of each Lender, or
(vii) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make
any determination or grant any consent hereunder, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, the Issuing
Bank or the Swingline Lender hereunder without the prior written consent of the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be. 
 (c) If, in connection with any proposed amendment, waiver or consent (a “Proposed Change”) requiring the consent of all Lenders, the consent of the Required Lenders is obtained, but the consent of
other Lenders is not obtained (any such Lender whose consent is not obtained being referred to herein as a “Non-Consenting Lender”), then, so long as the Administrative Agent is not a Non-Consenting Lender, the Borrowers may elect
to replace such Non-Consenting Lender as a Lender party to this Agreement, provided that, concurrently with such replacement, (i) another bank or other entity which is reasonably satisfactory to the Borrowers and the Administrative Agent
shall agree, as of such date, to purchase for cash the Advances and other Obligations due to the Non-Consenting Lender pursuant to an Assignment Agreement and to become a Lender for all purposes under this Agreement and to assume all obligations of
the Non-Consenting Lender to be terminated as of such date and to comply with the requirements of Section 9.04 applicable to assignments, and (ii) the Borrowers shall pay to such Non-Consenting Lender in same day funds on the day of such
replacement (1) all interest, fees and other amounts then accrued but unpaid to such Non-Consenting Lender by the Borrowers hereunder to and including the date of termination, and (2) an amount, if any, equal to the payment which would
have been due to such Lender on the day of such replacement under Section 2.16 had the Loans of such Non-Consenting Lender been prepaid on such date rather than sold to the replacement Lender. 
 SECTION 9.03. Expenses; Indemnity; Damage Waiver. (a) The Borrowers shall pay (i) all reasonable out-of-pocket expenses incurred by the
Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and
administration of this Agreement and any of the other Loan Documents (including without limitation the Collateral and any additional filings, documents, examinations or other actions with respect thereto) or any amendments, modifications or waivers
of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank 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 the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for
the Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or 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. 
 (b) The Borrowers shall indemnify the Administrative Agent, the Issuing Bank and each Lender, and each Related Party of any of the
foregoing Persons (each such Person being called an 

  

 62 

 
“Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses,
including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any
agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or Letter of
Credit or the use of the proceeds therefrom (including any refusal by the Issuing Bank 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 the Parent or any of its Subsidiaries, or any Environmental Liability related in any way to the Parent 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 and regardless of whether any Indemnitee is a party
thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and
nonappealable judgment to have resulted from the gross negligence or wilful misconduct of such Indemnitee. 
 (c) To the
extent that the Borrowers fail to pay any amount required to be paid by it to the Administrative Agent, the Issuing Bank or the Swingline Lender under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the
Administrative Agent, the Issuing Bank or the Swingline Lender, 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 Administrative Agent, the Issuing Bank or the Swingline Lender in its
capacity as such. 
 (d) To the extent permitted by applicable law, the Borrowers shall not assert, and 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 or any agreement or
instrument contemplated hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof. 
 (e) All
amounts due under this Section shall be payable promptly after written demand therefor. 
 SECTION 9.04. Successors and Assigns.
(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of
Credit), except that (i) the Borrowers may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrowers without such
consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. 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 (including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in paragraph (c) of this
Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement. 
 (b)(i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of
its rights and obligations under this Agreement 

  

 63 

 
(including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably
withheld) of: 
 (A) the Borrowers, provided that no consent of the Borrowers shall be required for an assignment to a
Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee; 
 (B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment of all or any portion of a Term Loan to a Lender, an Affiliate of a Lender or an Approved Fund; and

 (C) the Issuing Bank, provided that no consent of the Issuing Bank shall be required for an assignment of all
or any portion of a Term Loan. 
 (ii) Assignments shall be subject to the following additional conditions: 
 (A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the
assigning Lender’s Commitment or Loans of any Class, the amount of the Commitment or 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 Administrative Agent) shall not be less than $5,000,000 or, in the case of a Term Loan, $1,000,000 unless each of the Borrowers and the Administrative Agent otherwise consent, provided that no such consent of the Borrowers
shall be required if an Event of Default has occurred and is continuing; 
 (B) each partial assignment shall be made as an
assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement, provided that this clause shall not be construed to prohibit the assignment of a proportionate part of all the assigning
Lender’s rights and obligations in respect of one Class of Commitments or Loans; 
 (C) the parties to each assignment
shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and 
 (D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. 
 For the purposes of this Section 9.04(b), the term “Approved Fund” has the following meaning: 
 “Approved Fund” means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is
administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender. 
 (iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date
specified in each Assignment and Assumption the assignee thereunder shall be a party hereto 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 

  

 64 

 
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 2.15, 2.16, 2.17 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 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 paragraph (c) of this Section. 
 (iv) The Administrative Agent, acting for this purpose as an agent of the Borrowers, shall maintain at one of its offices 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 Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register
shall be deemed conclusive absent manifest error, and the Borrowers, the Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all
purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrowers, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

 (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the
assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment
required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee
shall have failed to make any payment required to be made by it pursuant to Section 2.05(c), 2.06(d) or (e), 2.07(b), 2.18(d) or 9.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the
information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register
as provided in this paragraph. 
 (c)(i) Any Lender may, without the consent of the Borrowers, the Administrative Agent, the
Issuing Bank or the Swingline Lender, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of
its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance
of such obligations and (C) the Borrowers, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this
Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision
of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b)
that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrowers agree that each Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 to the same extent as if it were a Lender and had acquired its
interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided such Participant agrees to be
subject to Section 2.18(c) as though it were a Lender. 
 (ii) A Participant shall not be entitled to receive any greater
payment under Section 2.15 or 2.17 than the applicable Lender would have been entitled to receive with respect to the participation 

  

 65 

 
sold to such Participant, unless the sale of the participation to such Participant is made with the Borrowers’ 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 2.17 unless the Borrowers are notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers,
to comply with Section 2.17(e) as though it were a Lender. 
 (d) Any Lender may at any time pledge or assign a
security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply
to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender
as a party hereto. 
 SECTION 9.05. Survival. All covenants, agreements, representations and warranties made by the Borrowers herein
and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the
making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or
knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount
payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.15, 2.16, 2.17 and 9.03 and Article VIII shall survive and
remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or
any provision hereof. 
 SECTION 9.06. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and
by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees
payable to the Administrative Agent 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 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which,
when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a
signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement. 
 SECTION
9.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without
affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. 
 SECTION 9.08. Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or 

  

 66 

 
demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the
Borrowers against any of and all the obligations of the Borrowers now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such
obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have. 
 SECTION 9.09. Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and
governed by the law of the State of New York. 
 (b) Each Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any
thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such
action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and
may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the Administrative Agent, the Issuing Bank or any Lender may otherwise have to bring any
action or proceeding relating to this Agreement against each Borrower or its properties in the courts of any jurisdiction. 
 (c) Each Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement 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 law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court. 
 (d) Each party to this Agreement irrevocably consents to
service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 
 SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY 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 THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY 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 BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 
 SECTION 9.11. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration
in interpreting, this Agreement. 
  

 67 

 SECTION 9.12. Confidentiality. Each of the Administrative Agent, the Issuing Bank and the Lenders
agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other
advisors (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, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit,
action or proceeding relating to this Agreement or the enforcement of rights hereunder, (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 or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to any Borrower and its
obligations, (g) with the consent of the Borrowers or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, the
Issuing Bank or any Lender on a nonconfidential basis from a source other than the Borrowers. For the purposes of this Section, “Information” means all information received from the Borrowers relating to the Borrowers or their
business, other than any such information that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Borrowers; provided that, in the case of information received from
the Borrowers after the date hereof, such information is clearly identified at the time of delivery as confidential. 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. 
 SECTION 9.13. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be
contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be
limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall
have been received by such Lender. 
 SECTION 9.14. USA PATRIOT Act. Each Lender that is subject to the requirements of the USA
Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”) hereby notifies each Borrower that pursuant to the requirements of 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 to identify each Borrower in accordance with the Act. 
 SECTION 9.15. Conversion of Currencies. (a) If, for the purpose of obtaining judgment in any court, it is necessary to convert a sum owing
hereunder in one currency into another currency, each party hereto agrees, to the fullest extent that it may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures in the relevant
jurisdiction the first currency could be purchased with such other currency on the Business Day immediately preceding the day on which final judgment is given. 
  

 68 

 (b) The obligations of each Borrower and LC Obligor in respect of any sum due to any
party hereto or any holder of the obligations owing hereunder (the “Applicable Creditor”) shall, notwithstanding any judgment in a currency (the “Judgment Currency”) other than the currency in which such sum is stated to be due
hereunder (the “Agreement Currency”), be discharged only to the extent that, on the Business Day following receipt by the Applicable Creditor of any sum adjudged to be so due in the Judgment Currency, the Applicable Creditor may in
accordance with normal banking procedures in the relevant jurisdiction purchase the Agreement Currency with the Judgment Currency; if the amount of the Agreement Currency so purchased is less than the sum originally due to the Applicable Creditor in
the Agreement Currency, such Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Applicable Creditor against such loss. The obligations of the Borrowers and LC Obligors contained in this
Section 9.15 shall survive the termination of this Agreement and the payment of all other amounts owing hereunder. 
  

 69 

 IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective
authorized officers as of the day and year first above written.
