forth in Section 2.4(e) below) and, after all Loans have been prepaid, make a Cash Collateral Deposit in an amount equal to 100% of the amount of such proceeds not so applied. The Borrower shall give the Lender prompt written notice of all insurance
and condemnation proceeds received by it or any Subsidiary on or after the Closing Date in excess of $200,000 per occurrence. 
  
 (d) If as of the end of any fiscal year of the Borrower, commencing with the fiscal year ending on September 30, 2005, the Senior Leverage
Ratio is greater than or equal to 1.50 to 1.00, the Borrower shall prepay the Term Loan (and such prepayment shall be applied as set forth in Section 2.4(e) below) in an amount equal to 50% of the Excess Cash Flow for such fiscal year. 

 
 (e) Each prepayment pursuant to clause (b), (c) or (d) of
this Section 2.4 shall be applied first, to the outstanding principal balance of the Term Loan, in the inverse order of maturity, second, in the case of clauses (b) and (c), to the Revolving Loans, and third, in the case of
clauses (b) and (c), to make a Cash Collateral Deposit with respect to outstanding Letters of Credit. Each prepayment shall be accompanied by payment in full of all accrued interest and, if applicable, accrued commitment fees thereon to and
including the date of such prepayment, together with any additional amounts owing pursuant to Section 2.14 hereof. Each prepayment of the Revolving Loans shall permanently reduce the Aggregate Revolving Loan Commitment in an amount equal to such
prepayment. 
  
 2.5 Conversion and Continuation
Options. (a) The Borrower may elect from time to time to convert LIBOR Loans to Prime Rate Loans by the Borrower giving the Administrative Agent at least two Business Days’ prior irrevocable written notice of such election pursuant to a
Continuation Notice, provided that any such conversion of LIBOR Loans may only be made on the last day of an Interest Period with respect thereto. Subject to Sections 2.9 and 2.11 hereof, the Borrower may elect from time to time to convert
Prime Rate Loans to LIBOR Loans by the Borrower giving the Administrative Agent at least three Eurodollar Business Days’ prior 

  

 -28- 

Table of Contents

 
irrevocable written notice of such election pursuant to a Continuation Notice. Any such notice of conversion to LIBOR Loans shall specify the length of the
initial Interest Period or Interest Periods therefor. All or any part of outstanding LIBOR Loans and, subject to Sections 2.9 and 2.11 hereof, Prime Rate Loans, may be converted as provided herein, provided that (i) any such conversion may
only be made if, after giving effect thereto, Section 2.6 below shall not have been contravened, (ii) no such Loan may be converted into a LIBOR Loan after the date that is one month prior to the Maturity Date and (iii) the Borrower shall not have
the right to elect to continue at the end of the applicable Interest Period, or to convert to, a LIBOR Loan if a Default shall have occurred and be continuing. 
  

(b) Any LIBOR Loan may be continued as such upon the expiration of the then current Interest Period with respect thereto by the
Borrower giving notice to the Administrative Agent, in accordance with the applicable provisions of the term “Interest Period” set forth in Section 1.1 above, of the length of the next Interest Period to be applicable to such LIBOR Loan,
provided that no LIBOR Loan may be continued as such (i) if, after giving effect thereto, Section 2.6 below would be contravened, (ii) after the date that is one month prior to the Maturity Date or (iii) if a Default shall have occurred and
be continuing and provided, further, that if the Borrower shall fail to give any required notice as described above in this Section or if such continuation is not permitted pursuant to the preceding proviso, such LIBOR Loans shall be
automatically converted to Prime Rate Loans on the last day of such then-expiring Interest Period. 
  
 2.6 Minimum Amounts of Tranches; Minimum Borrowings. All borrowings, conversions and continuations of LIBOR Loans hereunder and all selections of Interest Periods hereunder shall be in
such amounts and be made pursuant to such elections so that, after giving effect thereto, the aggregate principal amount of the Loans comprising each Tranche shall be equal to $100,000 or a whole multiple of $100,000 in excess thereof and, in any
case, there shall not be more than 7 Tranches. All borrowings of Prime Rate Loans shall be in a minimum amount of $100,000 or a whole multiple of $100,000 in excess thereof. 
  
 2.7 Interest Rates and Payment Dates. 
  
 (a) Each Loan shall (i) if a LIBOR Loan, bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the LIBOR Adjusted Rate plus the Applicable LIBOR Margin and (ii) if a Prime Rate Loan, bear interest at a rate per annum equal to the Prime Rate plus the Applicable Prime Rate Margin as adjusted daily.

  
 (b) If any Event of Default shall have
occurred and be continuing, all amounts outstanding hereunder shall, at the election of the Requisite Lenders in their sole discretion, bear interest at a rate per annum equal to the rate determined pursuant to Section 2.7(a) above plus 2% per
annum, from the date of the occurrence of such Event of Default until such Event of Default is no longer continuing (after as well as before judgment). 
  
 (c) Interest shall be payable in arrears on each Interest Payment Date; provided, however, that interest accruing pursuant
to paragraph (b) of this Section shall be payable on demand.

 2.8 Computation of Interest and Fees. Interest on the Loans and all other
Obligations shall be calculated on the basis of a 360-day year for the actual days elapsed; provided that interest on Prime Rate Loans shall be calculated on the basis of a year of 365 or 366 days, as applicable, for the actual days elapsed. Each
determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower in the absence of manifest error. 
  
 2.9 Inability to Determine Interest Rate. In the event that, prior to the first day of any Interest
Period, (a) the Lenders shall have determined (which determination shall be conclusive and binding upon the Borrower absent manifest error) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist
for ascertaining the LIBOR Adjusted Rate for such Interest Period or (b) the Lenders shall have determined that the LIBOR Adjusted Rate for such Interest Period will not adequately and fairly reflect the cost to the Lenders (as conclusively
certified by such Lenders) of making or maintaining their affected Loans during such Interest Period, the Lenders shall give telecopy or telephonic notice thereof to the Borrower as soon as practicable thereafter. If such notice is given, (i) any
LIBOR Loans requested to be made on the first day of such Interest Period shall accrue interest at the Prime Rate, (ii) Loans that were to have been converted on the first day of such Interest Period to LIBOR Loans shall be continued as Prime Rate
Loans and (iii) any outstanding LIBOR Loans shall be converted, on the first day of such Interest Period, to Prime Rate Loans. Until such notice has been withdrawn by the Lenders, no further LIBOR Loans shall be made or continued as such, nor shall
the Borrower have the right to convert Prime Rate Loans to LIBOR Loans. 
  
 2.10 Payments. All payments (including prepayments) to be made by the Borrower hereunder and under the Notes, whether on account of principal, interest, fees or otherwise, shall be made without setoff,
deduction or counterclaim and shall be made prior to 11:00 a.m., Los Angeles time, on the due date thereof to the Administrative Agent at its offices specified in Section 10.2, in Dollars and in immediately available funds. If any payment hereunder
(other than payments on the LIBOR Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day, and, with respect to payments of principal, interest thereon shall be payable at
the then applicable rate during such extension. If any payment on a LIBOR Loan becomes due and payable on a day other than a Eurodollar Business Day, the maturity thereof shall be extended to the next succeeding Eurodollar Business Day (and interest
shall continue to accrue thereon at the applicable rate) unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Eurodollar Business Day.

  
 2.11 Illegality. Notwithstanding any
other provision herein, if any change after the Closing Date in any Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Lender to maintain LIBOR Loans as contemplated by this Agreement, (a) the
commitment of such Lender hereunder to continue LIBOR Loans as such and convert Prime Rate Loans to LIBOR Loans shall forthwith be suspended during such period of illegality and (b) the Loans of such Lender then outstanding as LIBOR Loans, if any,
shall be converted automatically to Prime Rate Loans on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law. If any such conversion of a LIBOR Loan occurs on a day
which is not the last day of the then current 

  

 -30- 

Table of Contents

 
Interest Period with respect thereto, the Borrower shall pay to such Lender such amounts, if any, as may be required pursuant to Section 2.14 below. To the
extent that LIBOR Loans have been converted to Prime Rate Loans pursuant to this Section 2.11, all payments and prepayments of principal that otherwise would be applied to LIBOR Loans shall be applied instead to Prime Rate Loans. 
  
 2.12 Increased Costs. 
  
 (a) In the event that any change after the Closing Date in
any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law but, if not having the force of law, generally applicable to and complied with
by banks and financial institutions of the same general type as such Lender in the relevant jurisdiction) from any central bank or other Governmental Authority made subsequent to the Closing Date (a “Change in Law”): 
  
 (i) shall impose, modify or hold applicable
any reserve, special deposit, compulsory loan or similar requirements against assets held by, letters of credit issued by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other
acquisition of funds by, any office of such Lender or Applicable Lending Office which is not otherwise included in the determination of the LIBOR Adjusted Rate hereunder; or 
  
 (ii) shall impose on such Lender any other condition; 
  
 and the result of any of the foregoing is to increase the cost to such Lender
of issuing any Letter of Credit, or increase the cost to such Lender of converting into, continuing or maintaining LIBOR Loans, or to reduce any amount receivable hereunder in respect of any of the foregoing, in any case by an amount which such
Lender deems to be material, then, in any such case, the Borrower shall immediately pay to such Lender, upon the demand of such Lender and upon receipt of the certificate referenced below, any additional amounts necessary to compensate such Lender
for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this Section, it shall notify the Borrower of the event by reason of which it has become so entitled. A certificate as
to any additional amounts payable pursuant to this Section submitted by such Lender to the Borrower, which shall demonstrate in reasonable detail the computation of such amounts, shall be conclusive evidence of the accuracy of the information so
recorded, absent manifest error. Notwithstanding the foregoing, the Borrower shall not be required to compensate a Lender pursuant to this subsection 2.12(a) for any increased cost or reduction in respect of a period occurring more than six months
prior to the date on which such Lender notifies the Borrower of such increase or reduction and such Lender’s intention to claim compensation therefor, except, if the Change in Law giving rise to such increased cost or reduction is retroactive,
no such time limitation shall apply so long as such Lender requests compensation within six months from the date on which the applicable Governmental Authority informed such Lender of such Change in Law. This covenant shall survive the termination
of this Agreement, the expiration of the Letters of Credit and the payment of the Note and all other amounts payable hereunder. 
  
 (b) If, after the date of this Agreement, any Change in Law regarding capital adequacy affects the amount of capital required or expected
to be maintained by any Lender or 

  

 -31- 

Table of Contents

 
any corporation controlling such Lender, and such Lender (taking into consideration its or such corporation’s policies with respect to capital adequacy)
determines that the amount of capital maintained by such Lender or such corporation which is attributable to or based upon the Loans, the Letters of Credit or this Agreement must be increased as a consequence of such Change in Law by an amount
deemed by such Lender to be material, then, upon demand of such Lender the Borrower shall immediately pay to such Lender additional amounts sufficient to compensate such Lender or such corporation for the increased costs to such Lender or
corporation of such increased capital. Any such demand shall be accompanied by a certificate of such Lender setting forth in reasonable detail the computation of any such increased costs, which certificate shall be conclusive, absent manifest error.
Notwithstanding the foregoing, the Borrower shall not be required to compensate a Lender pursuant to this subsection 2.12(b) for any reduction in respect of a period occurring more than six months prior to the date on which such Lender notifies the
Borrower of such reduction and such Lender’s intention to claim compensation therefor, except, if the Change in Law giving rise to such reduction is retroactive, no such time limitation shall apply so long as such Lender requests compensation
within six months from the date on which the applicable Governmental Authority informed such Lender of such Change in Law. 
  
 2.13 Taxes. All payments made by the Borrower in respect of the Obligations shall be made free and clear of, and without deduction
or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental
Authority or any political subdivision or taxing authority thereof or therein, other than Excluded Taxes (all such non-Excluded Taxes being hereinafter called “Taxes”). If any Taxes are required to be withheld from any amounts
payable to any Lender in respect of the Obligations, the amounts so payable to such Lender shall be increased to the extent necessary to yield to such Lender (after payment of all Taxes) interest or any such other amounts payable hereunder at the
rates or in the amounts specified in this Agreement and the Notes. The Borrower agrees to indemnify each Lender for the full amount of Taxes (including any Taxes imposed or asserted by any Governmental Authority on amounts payable under this
Section), paid by such Lender. Whenever any Taxes are payable by the Borrower, as promptly as possible thereafter, the Borrower shall send to the Lenders a copy of an original official receipt received by the Borrower showing payment thereof or such
other evidence of payment reasonably satisfactory to the Lenders. If the Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Lenders the required receipts or other required documentary evidence, the
Borrower shall indemnify the Lenders for any incremental taxes, interest or penalties (and related reasonable fees and expenses of counsel) that may become payable by the Lenders as a result of any such failure. The agreements in this Section shall
survive the termination of this Agreement, the expiration of the Letters of Credit and the payment of the Notes and all other amounts payable hereunder. 
  
 2.14 Indemnity. The Borrower agrees to indemnify each Lender and to hold each Lender harmless from and to pay each Lender on demand
the amount of any liability, loss or expense arising from the reemployment of funds obtained by it or from fees payable to terminate the deposits from which such funds were obtained (including reasonable fees and expenses of counsel) which such
Lender may sustain or incur as a consequence of (a) default by the Borrower in payment when due of the principal amount of or interest on any LIBOR Loan, (b) default by the Borrower in making a borrowing of, conversion into or continuation of LIBOR

  

 -32- 

Table of Contents

 
Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (c) default by the Borrower in making
any prepayment after the Borrower has given a notice thereof in accordance with the provisions of this Agreement or (d) the making by the Borrower of a prepayment or conversion of LIBOR Loans on a day which is not the last day of an Interest Period
with respect thereto (including any prepayment required as a result of acceleration of the Loans under Section 8 hereof). Such Lender’s certificate as to such liability, loss or expense shall be deemed conclusive, absent manifest error. This
covenant shall survive the termination of this Agreement, the expiration of the Letters of Credit and the payment of the Notes and all other amounts payable hereunder. 
  
 2.15 Mitigation of Costs. If any Lender, by taking any other reasonable action, so long as making
such change or taking such other action is not disadvantageous to it in any financial, regulatory or other respect, can mitigate any adverse effect on the Borrower under Sections 2.11, 2.12 or 2.13 hereof, such Lender shall take such action.

  
 2.16 Upfront Fee; Unused Commitment
Fee. The Borrower agrees to pay to each Lender (i) an upfront fee based on such Lender’s pro rata share of the Aggregate Revolving Loan Commitment and the Aggregate Term Loan Commitment and computed at a rate equal to 1.00%, and (ii) an
unused commitment fee for the period from and including the Closing Date to but excluding the Maturity Date, based on the average aggregate amount, for each day during such period, of the Available Revolving Loan Commitment, and computed at a rate
equal to 0.25% per annum. Such upfront fee shall be due and payable to each Lender on the Closing Date; the unused commitment fee shall be payable in installments quarterly in arrears on the last day of each March, June, September and December and
on the Maturity Date, commencing on the first such date to occur after the Closing Date. 
  
 2.17 Administrative Agent’s Right to Assume Funds Available for Advances. Unless the Administrative Agent shall have been notified by any Lender no later than 10:00 a.m., Los Angeles
time, on the Business Day of the proposed funding by the Administrative Agent of any Loan that such Lender does not intend to make available to the Administrative Agent such Lender’s portion of the total amount of such Loan, the Administrative
Agent may assume that such Lender has made such amount available to the Administrative Agent on the date of the Loan and the Administrative Agent may, in reliance upon such assumption, make available to Borrower a corresponding amount. If the
Administrative Agent has made funds available to Borrower based on such assumption and such corresponding amount is not in fact made available to the Administrative Agent by such Lender, the Administrative Agent shall be entitled to recover such
corresponding amount on demand from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent promptly shall notify Borrower and Borrower shall pay
such corresponding amount to the Administrative Agent. The Administrative Agent also shall be entitled to recover from such Lender interest on such corresponding amount in respect of each day from the date such corresponding amount was made
available by the Administrative Agent to Borrower to the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to the daily Federal Funds Rate. Nothing herein shall be deemed to relieve any Lender from
its obligation to fulfill its share of the Commitments or to prejudice any rights which the Administrative Agent or Borrower may have against any Lender as a result of any default by such Lender hereunder.

each of which jurisdictions is set forth on Schedule 4.2 hereto, except for those jurisdictions where the failure to be so qualified or in good standing has not had and will not result in a Material Adverse Effect and (d) is in compliance
with all Requirements of Law except to the extent that the failure to comply therewith could not reasonably be expect to have a Material Adverse Effect. 
  
 4.3 Corporate Power; Authorization; Consents; Enforceable Obligations. (a) The Borrower and each of its Subsidiaries has the

the Borrower or such Subsidiary is a party thereto) enforceable against it in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law). 
  
 4.4 No Legal Bar. The execution, delivery and performance of this Agreement, the Notes and the other Loan Documents, and the
borrowings hereunder and the use of the proceeds thereof, will not violate any Requirement of Law or material Contractual Obligation of the Borrower or any Subsidiary, and will not result in, or require, the creation or imposition of any Lien on any
of its properties or revenues pursuant to any such Requirement of Law or such Contractual Obligation, except pursuant to the Loan Documents. 
  
 4.5 No Material Litigation. Except as set forth in Schedule 4.5 hereto, no litigation, investigation or proceeding of or

Effect. 
  
 (c) Except as set forth in Schedule
4.7 hereto, no Loan Party has received any notice of violation, alleged violation, non-compliance, liability or potential liability regarding environmental matters or compliance with Environmental Laws with regard to any of the Properties or the
business conducted at the Properties, nor does the Borrower have knowledge that any such notice will be received or is being threatened which has caused or could reasonably be expected to cause a Material Adverse Effect.

all material respects (the “Intellectual Property”). Except as set forth in Schedule 4.8, no claim which could reasonably be expected to have a Material Adverse Effect has been asserted and is pending by any Person
challenging or questioning the use of any such Intellectual Property or the validity or effectiveness of any such Intellectual Property, nor does the Borrower or any Subsidiary know of any valid basis for any such claim. To the Borrower’s
knowledge, except as set forth in Schedule 4.8 hereto, the use of such Intellectual Property by the Borrower and its Subsidiaries does not infringe in any material respect on the rights of any Person, nor, to the Borrower’s knowledge,

which reserves in conformity with GAAP have been provided on the books of the Borrower or such Subsidiary, as appropriate); as of the Closing Date, no tax Lien has been filed, and no claim which could reasonably be expected to have a Material
Adverse Effect is being asserted with respect to any such tax, fee or other charge.

 SECTION 9. THE ADMINISTRATIVE AGENT AND THE COLLATERAL AGENT

  
 9.1 Appointment and Authorization.
Subject to Section 9.8, each Lender hereby irrevocably appoints and authorizes the Administrative Agent and the Collateral Agent to take such action as agent on its behalf and to exercise such powers under the Loan Documents as are delegated to the
Administrative Agent or the Collateral Agent by the terms thereof or are reasonably incidental, as determined by the Administrative Agent or the Collateral Agent, thereto. This appointment and authorization are intended solely for the purpose of
facilitating the servicing of the Loans and the administration of the Collateral and do not constitute appointment of the Administrative Agent or the Collateral Agent as trustee for any Lender or as representative of any Lender for any other purpose
and, except as specifically set forth in the Loan Documents to the contrary, the Administrative Agent and the Collateral Agent shall take such action and exercise such powers only in an administrative and ministerial capacity. 
  
 9.2 The Agents and Their Affiliates. UBOC (and each
successor Administrative Agent) and BBH (and each successor Collateral Agent) have the same rights and powers under the Loan Documents as any other Lender and may exercise the same as though they were not the Administrative Agent and the Collateral
Agent, respectively, and the term “Lender” or “Lenders” includes UBOC and BBH in their individual capacities. UBOC (and each successor Administrative Agent) and BBH (and each successor Collateral Agent) have and their respective
Affiliates may accept deposits from, lend money to and generally engage in any kind of banking, trust or other business with the Borrower, any Subsidiary thereof, or any Affiliate of the Borrower or any Subsidiary thereof, as if they were not the
Administrative Agent and the Collateral Agent, respectively, and without any duty to account therefor to the Lenders. UBOC. (and each successor Administrative Agent) and BBH (and each successor Collateral Agent) need not account to any other Lender
for any monies received by them for reimbursement of their costs and expenses as Administrative Agent or Collateral Agent hereunder, or (subject to Section 10.8) for any monies received by them in their capacity as Lenders hereunder. Neither the
Administrative Agent nor the Collateral Agent shall be deemed to hold a fiduciary relationship with any Lender and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or otherwise
exist against the Administrative Agent or the Collateral Agent. 
  
 9.3 Proportionate Interest in any Collateral. The Collateral Agent, on behalf of all the Lenders, shall hold in accordance with the Loan Documents all items of any collateral or interests therein received or
held by the Collateral Agent. Subject to the Collateral Agent’s, the Administrative Agent’s and the Lenders’ rights to reimbursement for their costs and expenses hereunder (including reasonable attorneys’ fees and
disbursements and other professional services and the reasonably allocated costs of attorneys employed by the Collateral Agent, the Administrative Agent or a Lender), each Lender shall have an interest in the Lenders’ interest in such
collateral or interests therein in the same proportions that the aggregate Obligations owed such Lender under the Loan Documents bear to the aggregate Obligations owed under the Loan Documents to all the Lenders, without priority or preference among
the Lenders. 
  
 9.4 Lenders’ Credit
Decisions. Each Lender agrees that it has, independently and without reliance upon the Administrative Agent, the Collateral Agent, any other Lender or the directors, officers, agents, employees or attorneys of the Administrative Agent, the
Collateral 

  

 -63- 

Table of Contents

 
Agent or of any other Lender, and instead in reliance upon information supplied to it by or on behalf of Borrower and upon such other information as it has
deemed appropriate, made its own independent credit analysis and decision to enter into this Agreement. Each Lender also agrees that it shall, independently and without reliance upon the Administrative Agent, the Collateral Agent any other Lender or
the directors, officers, agents, employees or attorneys of the Administrative Agent, the Collateral Agent or of any other Lender, continue to make its own independent credit analyses and decisions in acting or not acting under the Loan Documents.

  
 9.5 Action by Administrative Agent and
Collateral Agent. 
  
 (a) Absent actual
knowledge of the Administrative Agent or the Collateral Agent of the existence of a Default, the Administrative Agent and the Collateral Agent may assume that no Default has occurred and is continuing, unless the Administrative Agent or the
Collateral Agent (or the Lender that is then the Administrative Agent or the Collateral Agent) has received notice from Borrower stating the nature of the Default or has received notice from a Lender stating the nature of the Default and that such
Lender considers the Default to have occurred and to be continuing. 
  
 (b) The Administrative Agent and the Collateral Agent have only those obligations under the Loan Documents as are expressly set forth therein. 
  
 (c) Except for any obligation expressly set forth in the Loan Documents and as long as the
Administrative Agent and the Collateral Agent may assume that no Event of Default has occurred and is continuing, the Administrative Agent and the Collateral Agent may, but shall not be required to, exercise its reasonable discretion to act or not
act, except that the Administrative Agent and the Collateral Agent shall be required to act or not act upon the instructions of the Requisite Lenders (or of all the Lenders, to the extent required by Section 10.1) and those instructions shall
be binding upon the Administrative Agent, the Collateral Agent and all the Lenders, provided that the Administrative Agent and the Collateral Agent shall not be required to act or not act if to do so would be contrary to any Loan Document or
to applicable Law or would result, in the reasonable judgment of the Administrative Agent or the Collateral Agent, in substantial risk of liability to the Administrative Agent or the Collateral Agent. 
  
 (d) If the Administrative Agent or the Collateral Agent has
received a notice specified in clause (a), the Administrative Agent or the Collateral Agent shall immediately give notice thereof to the Lenders and shall act or not act upon the instructions of the Requisite Lenders (or of all the Lenders, to the
extent required by Section 10.1), provided that the Administrative Agent or the Collateral Agent shall not be required to act or not act if to do so would be contrary to any Loan Document or to applicable Law or would result, in the
reasonable judgment of the Administrative Agent or the Collateral Agent, in substantial risk of liability to the Administrative Agent or the Collateral Agent, and except that if the Requisite Lenders (or all the Lenders, if required under
Section 10.1) fail, for five (5) Business Days after the receipt of notice from the Administrative Agent, to instruct the Administrative Agent or the Collateral Agent, then the Administrative Agent or the Collateral Agent, in its sole discretion,
may act or not act as it deems advisable for the protection of the interests of the Lenders. 
  

 -64- 

Table of Contents

 (e) The Administrative Agent and the Collateral Agent shall have no liability to any
Lender for acting, or not acting, as instructed by the Requisite Lenders (or all the Lenders, if required under Section 10.1), notwithstanding any other provision hereof. 
  
 9.6 Liability of Agents. Neither the Administrative Agent, the Collateral Agent, nor any directors,
officers, agents, employees or attorneys of the Administrative Agent or the Collateral Agent shall be liable for any action taken or not taken by them under or in connection with the Loan Documents, except for their own gross negligence or
willful misconduct. Without limitation on the foregoing, the Administrative Agent, the Collateral Agent and their respective directors, officers, agents, employees and attorneys: 
  
 (a) May treat the payee of any Note as the holder thereof until the Administrative Agent or the Collateral
Agent receives notice of the assignment or transfer thereof, in form satisfactory to the Administrative Agent or the Collateral Agent, signed by the payee, and may treat each Lender as the owner of that Lender’s interest in the Obligations for
all purposes of this Agreement until the Administrative Agent or the Collateral Agent receives notice of the assignment or transfer thereof, in form satisfactory to the Administrative Agent or the Collateral Agent, signed by that Lender; 

 
 (b) May consult with legal counsel (including
in-house legal counsel), accountants (including in-house accountants) and other professionals or experts selected by it, or with legal counsel, accountants or other professionals or experts for Borrower and/or their Subsidiaries or the
Lenders, and shall not be liable for any action taken or not taken by it in good faith in accordance with any reasonable advice of such legal counsel, accountants or other professionals or experts selected by it with reasonable care; 
  
 (c) Shall not be responsible to any Lender for any statement,
warranty or representation made in any of the Loan Documents or in any notice, certificate, report, request or other statement (written or oral) given or made in connection with any of the Loan Documents except for those expressly made by it;

  
 (d) Except to the extent expressly set
forth in the Loan Documents, shall have no duty to ask or inquire as to the performance or observance by Borrower or its Subsidiaries of any of the terms, conditions or covenants of any of the Loan Documents or to inspect any collateral or any
Property, books or records of Borrower or its Subsidiaries; 
  
 (e) Will not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, effectiveness, sufficiency or value of any Loan Document, any other instrument or writing furnished
pursuant thereto or in connection therewith, or any Collateral; 
  
 (f) Will not incur any liability by acting or not acting in reliance upon any Loan Document, notice, consent, certificate, statement, request or other instrument or writing reasonably believed by it to be genuine and
signed or sent by the proper party or parties; and 
  
 (g) Will not incur any liability for any arithmetical error in computing any amount paid or payable by Borrower or any Subsidiary or Affiliate thereof or paid or payable to or received or receivable from any Lender under any Loan Document,
including, without limitation, principal, interest, commitment fees, Advances and other amounts; provided that such error was 

  

 -65- 

Table of Contents

 
not the result of gross negligence or willful misconduct and provided further that, promptly upon discovery of such an error in computation, the
Administrative Agent, the Collateral Agent, the Lenders and (to the extent applicable) Borrower and/or its Subsidiaries or Affiliates shall make such adjustments as are necessary to correct such error and to restore the parties to the position that
they would have occupied had the error not occurred. 
  
 9.7 Indemnification. Each Lender shall, ratably in accordance with its Pro Rata Share of the Commitments (if the Commitments are then in effect) or in accordance with its proportion of the aggregate Indebtedness then evidenced by the
Notes (if the Commitments have then been terminated), indemnify and hold the Administrative Agent, the Collateral Agent and their respective directors, officers, agents, employees and attorneys harmless against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including reasonable attorneys’ fees and disbursements and allocated costs of attorneys employed by the
Administrative Agent or the Collateral Agent) that may be imposed on, incurred by or asserted against it or them in any way relating to or arising out of the Loan Documents (other than losses incurred by reason of the failure of Borrower to pay the
Indebtedness represented by the Notes) or any action taken or not taken by it as Administrative Agent or Collateral Agent thereunder, except such as result from its own gross negligence or willful misconduct. Without limitation on the
foregoing, each Lender shall reimburse the Administrative Agent or Collateral Agent upon demand for that Lender’s Pro Rata Share of any reasonable out-of-pocket cost or expense incurred by the Administrative Agent or the Collateral Agent in
connection with the negotiation, preparation, execution, delivery, amendment, waiver, restructuring, reorganization (including a bankruptcy reorganization), enforcement or attempted enforcement of the Loan Documents, to the extent that
Borrower or any other party is required by Section 10.5 to pay that cost or expense but fails to do so upon demand. Nothing in this Section 9.7 shall entitle the Administrative Agent, the Collateral Agent or any indemnitee referred to above to
recover any amount from the Lenders if and to the extent that such amount has theretofore been recovered from Borrower or any of its Subsidiaries. To the extent that the Administrative Agent, the Collateral Agent or any indemnitee referred to above
is later reimbursed such amount by Borrower or any of its Subsidiaries, it shall return the amounts paid to it by the Lenders in respect of such amount. 
  
 9.8 Successor Agents. The Administrative Agent and the Collateral Agent may, and at the request of the Requisite Lenders shall,
resign as Administrative Agent or Collateral Agent upon reasonable notice to the Lenders and Borrower effective upon acceptance of appointment by a successor Administrative Agent or Collateral Agent. If the Administrative Agent or Collateral Agent
shall resign as Administrative Agent or Collateral Agent under this Agreement, the Requisite Lenders shall appoint from among the Lenders a successor Administrative Agent or Collateral Agent for the Lenders, which successor Administrative Agent or
Collateral Agent shall be subject to approval by the Borrower (and such approval shall not be unreasonably withheld or delayed). If no successor Administrative Agent or Collateral Agent is appointed prior to the effective date of the resignation of
the Administrative Agent or Collateral Agent, the Administrative Agent or Collateral Agent may appoint, after consulting with the Lenders and Borrower, a successor Administrative Agent or Collateral Agent from among the Lenders. Upon the acceptance
of its appointment as successor Administrative Agent or Collateral Agent hereunder, such successor Administrative Agent or Collateral Agent shall succeed to all the rights, powers and duties of the retiring Administrative Agent or Collateral Agent
and the term 

  

 -66- 

Table of Contents

 
“Administrative Agent” or “Collateral Agent” shall mean such successor Administrative Agent or Collateral Agent and the retiring
Administrative Agent’s or Collateral Agent’s appointment, powers and duties as Administrative Agent or Collateral Agent shall be terminated. After any retiring Administrative Agent’s or Collateral Agent’s resignation hereunder as
Administrative Agent or Collateral Agent, the provisions of this Section 9 and Section 10.5 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent or Collateral Agent under this Agreement.
Notwithstanding the foregoing, if (a) the Administrative Agent or Collateral Agent has not been reimbursed for any expense reimbursable to it under Section 10.5, in either case for a period of at least one (1) year and (b) no successor
Administrative Agent or Collateral Agent has accepted appointment as Administrative Agent or Collateral Agent by the date which is thirty (30) days following a retiring Administrative Agent’s or Collateral Agent’s notice of resignation,
the retiring Administrative Agent’s or Collateral Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Administrative Agent or Collateral Agent hereunder until such time,
if any, as the Requisite Lenders appoint a successor Administrative Agent or Collateral Agent as provided for above. 
  
 9.9 No Obligations of Borrower. Nothing contained in this Section 9 shall be deemed to impose upon Borrower any obligation in
respect of the due and punctual performance by the Administrative Agent or the Collateral Agent of its obligations to the Lenders under any provision of this Agreement, and Borrower shall have no liability to the Administrative Agent, the Collateral
Agent or any of the Lenders in respect of any failure by the Administrative Agent, the Collateral Agent or any Lender to perform any of its obligations to the Administrative Agent, the Collateral Agent or the Lenders under this Agreement. Without
limiting the generality of the foregoing, where any provision of this Agreement relating to the payment of any amounts due and owing under the Loan Documents provides that such payments shall be made by Borrower to the Administrative Agent for the
account of the Lenders, Borrower’s obligations to the Lenders in respect of such payments shall be deemed to be satisfied upon the making of such payments to the Administrative Agent in the manner provided by this Agreement. In addition,
Borrower may rely on a written statement by the Administrative Agent to the effect that it has obtained the written consent of the Requisite Lenders or all of the Lenders, as applicable under Section 10.1, in connection with a waiver, amendment,
consent, approval or other action by the Lenders hereunder, and shall have no obligation to verify or confirm the same. 
  
 SECTION 10. MISCELLANEOUS 
  
 10.1 Amendments and Waivers. Neither this Agreement, the Notes, any other Loan Document, nor any terms hereof or thereof may be
amended, supplemented or modified except in accordance with the provisions of this Section. With the prior written consent of the Requisite Lenders and the Borrower, the Borrower may, from time to time, enter into written amendments, supplements or
modifications hereto and to the other Loan Documents for the purposes of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders, the Borrower or any other Loan Party hereunder or
thereunder or waiving, on such terms and conditions as may be specified in such instrument, any of the requirements of this Agreement or the Notes or the other Loan Documents or any Default and its consequences; provided, however, that

rights and obligations under this Agreement and the other Loan Documents except for a Subsidiary in connection with an Asset Disposition permitted by this Agreement; or (ii) release any Loan Party from any liability under its respective Loan
Documents except for a Subsidiary in connection with an Asset Disposition permitted by this Agreement; or (iii) release any material portion of the Collateral or any material portion of the Guarantor Collateral, except in connection with any Asset
Disposition permitted by this Agreement; or (iv) amend, modify or waive, directly or indirectly, any of the provisions of Sections 2.1(f) or 2.10 hereof (regarding pro rata payments); or (v) amend, modify or waive any provision of this Agreement
requiring the consent or approval of the Lenders, in each case without the written consent of each Lender. Any such waiver and any such amendment, supplement or modification shall be binding upon the Borrower, the other Loan Parties, the Agents, the
Lenders and all future holders of the Notes. In the case of any waiver, the Borrower, the other Loan Parties, the Agents, and the Lenders shall be restored to their former position and rights hereunder and under the outstanding Notes and any other
Loan Documents, and any Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default, or impair any right consequent thereon.

other communications to or upon the respective parties hereto to be effective shall be in writing (including notices given by facsimile which are preceded by telephone notification to the recipient), and, unless otherwise expressly provided herein,

as set forth on the signature pages hereof, or in the Assignment and Acceptance pursuant to which a Person becomes a party hereto, or to such other address as may be hereafter notified by the respective parties hereto; provided that any
notice, request or demand to or upon the Administrative Agent or any Lender pursuant to Sections 2.1, 2.2, 2.3, 2.4 or 2.5 hereof shall not be effective until received. 
  
 The Administrative Agent shall be entitled to rely and act upon telephonic notices purportedly given by or
on behalf of the Borrower even if (i) such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, (ii) such notices are found not to have been authorized by
the Borrower or (iii) the terms thereof, as understood by the recipient, varied from any confirmation thereof. The Borrower shall indemnify the Lenders from all losses, costs, expenses and liabilities resulting from the reliance by the Agent on any
such notice. 
  
 10.3 No Waiver; Cumulative
Remedies. No failure to exercise and no delay in exercising, on the part of the Lenders, any right, remedy, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies,
powers and privileges provided by law.

following the Closing Date, each Lender may assign to one or more Eligible Assignees all or any portion of its Pro Rata Share of the Commitments; provided that (i) such Eligible Assignee, if not then a Lender or an Affiliate of the assigning
Lender, shall be approved by the Agents and (if no Event of Default then exists) the Borrower (neither of which approvals shall be unreasonably withheld or delayed), (ii) such assignment shall be evidenced by a Commitment Assignment and Acceptance
substantially in the form attached as Exhibit K hereto (a “Commitment Assignment and Acceptance”), a copy of which shall be furnished to the Administrative Agent as hereinbelow provided, (iii) except in the case of an
assignment to an Affiliate of the assigning Lender or to another Lender the assignment shall not assign a Pro Rata Share of the Commitments that is equivalent to less than $5,000,000 and (iv) the effective date of any such assignment shall be as
specified in the Commitment Assignment and Acceptance, but not earlier than the date which is five (5) Business Days after the date the Administrative Agent has received the Commitment Assignment and Acceptance. Upon the effective date of such
Commitment Assignment and Acceptance, the Eligible Assignee named therein shall be a Lender for all purposes of this Agreement, with the Pro Rata Share of the Commitments therein set forth and, to the extent of such Pro Rata Share, the assigning
Lender shall be released from its further obligations under this Agreement. The Borrower agrees that it shall execute and deliver (against delivery by the assigning Lender to the Borrower of its Notes) to such assignee Lender, Notes evidencing that
assignee Lender’s Pro Rata Share of the Commitments, and to the assigning Lender, Notes evidencing the remaining balance of the Pro Rata Share retained by the assigning Lender. 
  
 (d) By executing and delivering a Commitment Assignment and Acceptance, the Eligible Assignee thereunder
acknowledges and agrees that: (i) other than the representation and warranty that it is the legal and beneficial owner of the Pro Rata Share of the Commitments being assigned thereby free and clear of any adverse claim, the assigning Lender has made
no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness or sufficiency
of this Agreement or any other Loan Document; (ii) the assigning Lender has made no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance by the Borrower of the
Obligations; (iii) it has received a copy of this Agreement, together with copies of the most recent financial statements delivered pursuant to Section 6.1 hereof and such other documents and information as it has deemed appropriate to make its own
credit analysis and decision to enter into such Commitment Assignment and Acceptance; (iv) it will, independently 

  

 -70- 

Table of Contents

 
and without reliance upon the Administrative Agent, the Collateral Agent or any Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) it appoints and authorizes the Agents to take such respective actions and to exercise such respective powers under this
Agreement as are delegated to the Agents by this Agreement; and (vi) it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Lender. 
  
 (e) The Administrative Agent shall maintain at the
Administrative Agent’s Office a copy of each Commitment Assignment and Acceptance delivered to it and a register (the “Register”) of the name and address of each of the Lenders and the Pro Rata Share of the Commitments held by each
Lender, giving effect to each Commitment Assignment and Acceptance. The Register shall be available during normal business hours for inspection by the Borrower or any Lender upon reasonable prior notice to the Administrative Agent. After receipt of
a completed Commitment Assignment and Acceptance executed by any Lender and an Eligible Assignee, and receipt of an assignment fee of $2,500 from such Lender or Eligible Assignee, the Administrative Agent shall, promptly following the effective date
thereof, provide to Borrower and the Lenders a revised Schedule 1.1 giving effect thereto. The Borrower, the Administrative Agent and the Lenders shall deem and treat the Persons listed as Lenders in the Register as the holders and owners of
the Pro Rata Share of the Commitments listed therein for all purposes hereof, and no assignment or transfer of any such Pro Rata Share of the Commitments shall be effective, in each case unless and until a Commitment Assignment and Acceptance
effecting the assignment or transfer thereof shall have been accepted by the Administrative Agent and recorded in the Register as provided above. Prior to such recordation, all amounts owed with respect to the applicable Pro Rata Share of the
Commitments shall be owed to the Lender listed in the Register as the owner thereof, and any request, authority or consent of any Person who, at the time of making such request or giving such authority or consent, is listed in the Register as a
Lender shall be conclusive and binding on any subsequent holder, assignee or transferee of the corresponding Pro Rata Share of the Commitments. 
  
 (f) Each Lender may from time to time grant participations to one or more banks or other financial institutions in a portion of its Pro
Rata Share of the Commitments; provided, however, that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of
such obligations, (iii) the participating banks or other financial institutions shall not be a Lender hereunder for any purpose, (iv) the Borrower, the Administrative Agent 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, (v) the participation interest shall be expressed as a percentage of the granting Lender’s Pro Rata Share of the Commitments as it then exists and shall
not restrict an increase in the Commitments, or in the granting Lender’s Pro Rata Share of the Commitments, so long as the amount of the participation interest is not affected thereby and (vi) the consent of the holder of such participation
interest shall not be required for amendments or waivers of provisions of the Loan Documents other than those which (A) extend the Maturity Date, or any other date upon which any payment of money is due to the Lenders, (B) reduce the rate of
interest on the Notes, any fee or any other monetary amount payable to the Lenders, (C) reduce the amount of any installment of principal due under the Notes, (D) release any Subsidiary Guarantee, or (E) release any Collateral from the Lien of the
Collateral Documents, 

  

 -71- 

Table of Contents

 
except if such release of Collateral or Subsidiary Guarantee occurs in connection with any Asset Disposition permitted hereunder, in which case such release
shall not require the consent of any of the Lenders or of any holder of a participation interest in the Commitments. 
  
 10.7 Right of Setoff. If an Event of Default has occurred and is continuing, the Administrative Agent or any Lender (but in each
case only with the consent of the Requisite Lenders) may (subject to Section 10.8 hereof) exercise its rights under Article 9 of the Uniform Commercial Code and other applicable laws and, to the extent permitted by applicable laws, apply any funds
in any deposit account maintained with it by the Borrower and/or any Property of the Borrower in its possession against the Obligations. 
  
 10.8 Sharing of Setoffs. Each Lender severally agrees that if it, through the exercise of any right of setoff, banker’s lien
or counterclaim against the Borrower, or otherwise, receives payment of the Obligations held by it that is ratably more than any other Lender, through any means, receives in payment of the Obligations held by that Lender, then, subject to applicable
laws: (a) the Lender exercising the right of setoff, banker’s lien or counterclaim or otherwise receiving such payment shall purchase, and shall be deemed to have simultaneously purchased, from each of the other Lenders a participation in the
Obligations held by the other Lenders and shall pay to the other Lenders a purchase price in an amount so that the share of the Obligations held by each Lender after the exercise of the right of setoff, banker’s lien or counterclaim or receipt
of payment shall be in the same proportion that existed prior to the exercise of the right of setoff, banker’s lien or counterclaim or receipt of payment; and (b) such other adjustments and purchases of participations shall be made from time to
time as shall be equitable to ensure that all of the Lenders share any payment obtained in respect of the Obligations ratably in accordance with each Lender’s share of the Obligations immediately prior to, and without taking into account, the
payment; provided that, if all or any portion of a disproportionate payment obtained as a result of the exercise of the right of setoff, banker’s lien, counterclaim or otherwise is thereafter recovered from the purchasing Lender by the
Borrower or any Person claiming through or succeeding to the rights of the Borrower, the purchase of a participation shall be rescinded and the purchase price thereof shall be restored to the extent of the recovery, but without interest. Each Lender
that purchases a participation in the Obligations pursuant to this Section 10.8 shall from and after the purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the
portion of the Obligations purchased to the same extent as though the purchasing Lender were the original owner of the Obligations purchased. The Borrower expressly consents to the foregoing arrangements and agrees that any Lender holding a
participation in an Obligation so purchased pursuant to this Section 10.8 may exercise any and all rights of setoff, banker’s lien or counterclaim with respect to the participation as fully as if the Lender were the original owner of the
Obligation purchased. 
  
 10.9 Foreign Lenders
and Participants. Each Lender that is incorporated or otherwise organized under the laws of a jurisdiction other than the United States of America or any State thereof or the District of Columbia shall deliver to the Borrower (with a copy to the
Administrative Agent), on or before the Closing Date (or on or before accepting an assignment or receiving a participation interest herein pursuant to Section 10.6(c) hereof, if applicable): 
  
 (A) properly completed and duly executed
copies of Internal Revenue Service Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party, 
  

 -72- 

Table of Contents

 (B) properly completed and duly executed copies of Internal Revenue
Service Form W-8ECI, 
  
 (C) in
the case of such a Lender claiming the benefits of the exemption “portfolio interest” under Section 881(c) of the Code, (A) a duly executed certificate to the effect that such Lender is not (i) a “bank” within the meaning of
Section 881(c)(3)(A) of the Code, (ii) a ten-percent shareholder (within the meaning of Section 881(c)(3)(B) of the Code) of the Borrower or (iii) a controlled foreign corporation described in Section 881(c)(3)(C) of the Code and (B) properly
completed and duly executed copies of Internal Revenue Service Form W-8BEN. 
  
 (D) properly completed and duly executed copies of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in any Tax, 
  
 in each case together with such supplementary documentation as may be
prescribed by applicable law to permit the Borrower and the Administrative Agent to determine the withholding or deduction required to be made, if any. 
  
 Thereafter and from time to time, each such Lender shall (a) promptly submit to the Borrower (with a copy to the Administrative Agent),
such additional duly completed and signed copies of one of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may then be available under then current United States laws and
regulations to avoid, or such evidence as is satisfactory to the Borrower and the Administrative Agent of any available exemption from, United States withholding taxes in respect of all payments to be made to such Lender by the Borrower pursuant to
this Agreement and (b) take such steps as shall not be materially disadvantageous to it, in the reasonable judgment of such Lender, and as may be reasonably necessary to avoid any requirement of applicable laws that the Borrower make any deduction
or withholding for taxes from amounts payable to such Lender. In the event that the Borrower or the Administrative Agent become aware that a participation has been granted pursuant to Section 10.6(c) hereof, to a financial institution that is
incorporated or otherwise organized under the Laws of a jurisdiction other than the United States of America, any State thereof or the District of Columbia, then, upon request made by the Borrower or the Administrative Agent to the Lender which
granted such participation, such Lender shall cause such participant financial institution to deliver the same documents and information to the Borrower and the Administrative Agent as would be required under this Section if such financial
institution were a Lender. 
  
 Without limiting
the generality of the foregoing, in the event that any Lender that is incorporated or otherwise organized under the laws of a jurisdiction other than the United States of America or any State thereof or the District of Columbia does not act or
ceases to act for its own account with respect to any portion of any sums paid or payable to such Lender under 

  

 -73- 

Table of Contents

 
any of the Loan Documents (for example, in the case of a typical participation by such Lender) such Lender shall deliver to the Administrative Agent and the
Borrower (in such number of copies as shall be requested by the recipient), on or prior to the date such Person becomes a Lender, or on such later date when such Lender ceases to act for its own account with respect to any portion of any such sums
paid or payable, and from time to time thereafter, as may be necessary in the determination of the Borrower or the Administrative Agent (each in the reasonable exercise of its discretion): 
  
 (1) duly executed and properly completed
copies of the forms and statements required to be provided by such Lender under this Section 10.9, to establish the portion of any such sums paid or payable with respect to which such Lender acts for its own account and may be entitled to an
exemption from or a reduction of the applicable Tax; and 
  
 (2) duly executed and properly completed copies of Internal Revenue Service Form W-8IMY (or any successor forms) properly completed and duly executed by such Lender, together with any information, if any, such Lender
chooses to transmit with such form, and any other certificate or statement of exemption required under the Code or the regulations thereunder, to establish that such Lender is not acting for its own account with respect to a portion of any such sums
payable to such Lender. 
  
 10.10
Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument.
Delivery of an executed counterpart of a signature page to this Agreement by telecopier shall be effective as delivery of a manually executed counterpart of this Agreement. 
  
 10.11 Severability. Any provision of this Agreement which is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction. 
  
 10.12 Integration. This Agreement, together with the other Loan Documents, represents the entire agreement of the Borrower and the Lenders with respect to the subject matter hereof, and there are no promises,
undertakings, representations or warranties by either Lender relative to the subject matter hereof not expressly set forth or referred to herein or in the other Loan Documents. 
  
 10.13 GOVERNING LAW. THIS AGREEMENT AND THE NOTES AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER
THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF CALIFORNIA (WITHOUT REFERENCE TO ITS CHOICE OF LAW RULES).

 10.14 Consent to Jurisdiction; Waiver of Jury Trial. 
  
 (a) Each party hereto hereby irrevocably and
unconditionally 
  
 (i) submits
for itself and its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general
jurisdiction of the courts of the State of California, the courts of the United States of America for the Southern District of California, and appellate courts from any thereof; 
  
 (ii) consents that any such action or proceeding may be brought in such courts and waives
any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient forum and agrees not to plead or claim the same; 
  
 (iii) agrees that service of process in any
such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to any party at its address set forth in Section 10.2 hereof; 
  
 (iv) agrees that nothing herein shall affect
the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and 
  
 (v) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or
proceeding referred to in this subsection any punitive damages. 
  
 (b) THE BORROWER AND EACH LENDER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY
COUNTERCLAIM HEREIN OR THEREIN. 
  
 10.15
Acknowledgements. The Borrower hereby acknowledges that: 
  
 (a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents; 
  
 (b) the Lenders do not have any fiduciary relationship to the Borrower solely by virtue of
any of the Loan Documents, and the relationship pursuant to the Loan Documents between the Lenders, on one hand, and the Borrower on the other hand, is solely that of creditor and debtor; 
  
 (c) no joint venture exists between the
Borrower and the Lenders; and 
  
 (d) the obligations of the Lenders hereunder are several and not joint or joint and several. Nothing contained in this Agreement or any other Loan Document and no action taken by the Lenders or either of them pursuant hereto or thereto may,
or may be deemed to, make the Lenders a partnership, an association, a joint venture or other entity, either between 

  

 -75- 

Table of Contents

 
themselves or with the Borrower or any Affiliate of the Borrower. A default by either Lender will not increase the pro rata share of the Commitments
attributable to the other Lender. If one Lender defaults, the other Lender not in default may, if it desires, assume (in such proportion as the nondefaulting Lender agrees) the obligations of the Lender in default, but is not obligated to do so.

  
 10.16 Headings. Section headings herein
are included for convenience of reference only and shall not constitute a part of this Agreement for any other purpose. 
  
 10.17 Confidentiality. Each Lender shall take normal and reasonable precautions to maintain the confidentiality of all non-public
information obtained pursuant to the requirements of this Agreement which has been identified in writing as such by any Loan Party but may, in any event, make disclosures (a) reasonably required by any bona fide transferee, assignee or participant
in connection with the contemplated transfer or assignment of any of the Revolving Loan Commitments, the Term Loan Commitments, the Loans, any participation in Letters of Credit or participation in any of the foregoing or (b) as required or
requested by any governmental agency or representative thereof or as required pursuant to legal process or (c) to its attorneys and accountants or (d) as required by law or (e) in connection with litigation involving such Lender; provided that (i)
such transferee, assignee or participant agrees in writing to comply with the provisions of this Section 10.17 unless specifically prohibited by applicable law or court order and (ii) in no event shall such Lender be obligated or required to return
any materials furnished by the Borrower and its Subsidiaries.

fees contracted for, charged, received, paid or agreed to be paid to Noteholders exceed the maximum amount permissible under such applicable law. If, from any circumstance whatsoever, interest and fees would otherwise be payable to Agent or
Noteholders in excess of the maximum amount permissible under applicable law, the interest and fees shall be reduced to the maximum amount permitted under applicable law. If from any circumstance, Agent or Noteholders shall have received anything of
value deemed interest by applicable law in excess of the maximum lawful amount, an amount equal to any excess of interest shall be applied to the reduction of the principal amount of the Notes, in such manner as may be determined by Noteholders, and
not to the payment of fees or interest, or if such excessive interest exceeds the unpaid balance of the principal amount of the Notes, such excess shall be refunded to the Company. 
  

 SECTION 3.08 Sharing of Payments, Etc. If any Noteholder shall obtain any payment (whether

forthwith purchase from the other Noteholders such participations in the Notes owing to them as shall be necessary to cause such purchasing Noteholder to share the excess payment ratably with each of them, provided, however, that if
all or any portion of such excess payment is thereafter recovered from such purchasing Noteholder, such purchase from each Noteholder shall be rescinded and such Noteholder shall repay to the purchasing Noteholder the purchase price to the extent of
such recovery together with an amount equal to such Noteholder’s ratable share (according to the proportion of (i) the amount of such Noteholder’s required repayment to (ii) the total amount so recovered from the purchasing Noteholder) of
any interest or other amount paid or payable by the purchasing Noteholder in respect of the total amount so recovered. The Company agrees that any Noteholder so purchasing a participation from another Noteholder pursuant to this Section 3.08 or any
other provision of this Agreement may, to the fullest extent permitted by law, exercise all of its rights of payment (including the right to set-off) with respect to such participation as fully as if such Noteholder were the direct creditor of the

 SECTION 10.03. No Waiver; Remedies. No failure on the part of the Agent or any Noteholder to exercise, and no delay in exercising, any right under
any of the Note Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any right under any of the Note Documents preclude any other or further exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law. 
  
 SECTION 10.04. Costs and Expenses. The Company agrees to pay on demand all costs and expenses of the Agent (including reasonable attorney’s fees) in connection with the preparation, amendment,
modification, enforcement (including, without limitation, in appellate, bankruptcy, insolvency, liquidation, reorganization, moratorium or other similar proceedings) or restructuring of the Note Documents. 
  
 SECTION 10.05. Indemnity. Whether or not the transactions contemplated
hereby shall be consummated, the Company agrees to indemnify, pay and hold the Agent, and each 

  

 
Noteholder, and the shareholders, officers, directors, employees and agents of the Agent and each Noteholder, harmless from and against any and all claims,
liabilities, losses, damages, costs and expenses (whether or not any of the foregoing Persons is a party to any litigation), including, without limitation, reasonable attorneys’ fees and costs and costs of investigation, document production,
attendance at a deposition, or other discovery, with respect to or arising out of this Agreement or the Note Documents or any use of proceeds hereunder, or any claim, demand, action or cause of action being asserted against the Company or any of its
Subsidiaries (collectively, the “Indemnified Liabilities”), provided that the Company shall have no obligation hereunder with respect to Indemnified Liabilities arising from the gross negligence or willful misconduct of any
such Persons. If any claim is made, or any action, suit or proceeding is brought, against any Person indemnified pursuant to this Section, the indemnified Person shall notify the Company of such claim or of the commencement of such action, suit or
proceeding, and the Company will assume the defense of such action, suit or proceeding, employing counsel selected by the Company and reasonably satisfactory to the indemnified Person, and pay the fees and expenses of such counsel. This covenant
shall survive termination of this Agreement and payment of the outstanding Notes. 
  
 SECTION 10.06. Transfer of Notes. 
  
 (a) Noteholders acknowledge that the Notes have not been registered under the Securities Act and may be resold only if registered pursuant to the provisions of the Securities Act or if an exemption from registration
is available, and that the Credit Parties are not required to register the Notes. 
  
 (b) Each of the Noteholders hereby represents and warrants to the Credit Parties that it is an “accredited investor” within the meaning of Rule 501(a) under the Securities Act and is acquiring the Notes for
investment for its own account, with no present intention of dividing its participation with others (except for a potential transfer or transfers of the Notes to an affiliate or affiliates of Noteholders) or reselling or otherwise distributing the
same in violation of the Securities Act or any applicable state securities laws. The Credit Parties may place an appropriate legend on the Notes owned by Noteholders concerning the restrictions set forth in this Section 10.06. Upon the assignment or
transfer by Noteholders or any of its successors or assignees of all or any part of the Notes, the term “Noteholder” as used herein shall thereafter mean, to the extent thereof, the then holder or holders of such Notes, or portion thereof.

  
 (c) Subject to Section 10.06(b) hereof, a holder of a Note may
transfer such Note to a new holder, or may exchange such Note for Notes of different denominations (but in no event of denominations of less than $100,000 in original principal amount), by surrendering such Note to the Company duly endorsed for
transfer or accompanied by a duly executed instrument of transfer naming the new holder (or the current holder if submitted for exchange only), together with written instructions for the issuance of one or more new Notes specifying the respective
principal amounts of each new Note and the name of each new holder and each address therefor. The Company shall simultaneously deliver to such holder or its designee such new Notes, shall mark the surrendered Notes as canceled and shall provide
notice of such transfer to Agent. In lieu of the foregoing procedures, a holder may assign a Note (in whole but not in part) to a new holder by sending written notice to the Company and Agent of such assignment specifying the new holder’s name
and address; in such case, the Company shall 

  

 
promptly acknowledge such assignment in writing to both the old and new holder. The Company shall not be required to recognize any subsequent holder of a
Note unless and until the Company have received reasonable assurance that all applicable transfer taxes have been paid. 
  
 (d) Upon receipt of evidence reasonably satisfactory to the Company of the mutilation, destruction, loss or theft of any Notes and the ownership thereof,
the Company shall, upon the written request of the holder of such Notes, execute and deliver in replacement thereof new Notes in the same form, in the same original principal amount and dated the same date as the Notes so mutilated, destroyed, lost
or stolen; and such Notes so mutilated, destroyed, lost or stolen shall then be deemed no longer outstanding hereunder. If the Notes being replaced have been mutilated, they shall be surrendered to the Company; and if such replaced Notes have been
destroyed, lost or stolen, such holder shall furnish the Company with an indemnity in writing to save it harmless in respect of such replaced Note. 
  
 (e) Nothing contained in this Section 10.06 shall limit the full force or effect of any representation, agreement or warranty made herein or in connection
herewith to Noteholder. 
  
 SECTION 10.07. Effectiveness;
Binding Effect; Governing Law. This Agreement shall become effective when it shall have been executed by the Company, the Agent and each Noteholder and thereafter shall be binding upon and inure to the benefit of the Company, the Agent, each
Noteholder and their respective successors and assigns, except that the Company shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the Agent and all the Noteholders. THIS AGREEMENT AND
THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF CALIFORNIA WITHOUT GIVING EFFECT TO ITS CHOICE OF LAW PRINCIPLES WHICH WOULD RESULT IN THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION. 
  
 SECTION 10.08. Waiver of Jury Trial. EACH OF THE PARTIES TO THIS
AGREEMENT HEREBY AGREES TO WAIVE ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE OTHER NOTE DOCUMENTS OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS
NOTE TRANSACTION OR THE LENDER/BORROWER RELATIONSHIP THAT IS BEING ESTABLISHED. 
  
 SECTION 10.09. Consent to Jurisdiction. All judicial proceedings brought against the Company with respect to this Agreement and the Note Documents may be brought in any state or federal court of competent
jurisdiction in the State of California, and by execution and delivery of this Agreement, the Company accepts for itself and in connection with its properties, generally and unconditionally, the nonexclusive jurisdiction of the aforesaid courts, and
irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement. The Company irrevocably waives any right it may have to assert the doctrine of forum non conveniens or to object to venue to the
extent any proceeding is brought in accordance with this Section. 
  

 SECTION 10.10. Entire Agreement. This Agreement with Exhibits and Schedules and the other Note
Documents embody the entire agreement and understanding between the parties hereto and supersedes all prior agreements and understandings relating to the subject matter hereof. 
  
 SECTION 10.11. Separability of Provisions; Headings. In case any one or more of the provisions contained in this
Agreement should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby. Section headings in this Agreement are
included for convenience of reference only and shall not be given any substantive effect. 
  
 SECTION 10.12. Obligations Several. The obligation of each Noteholder hereunder is several, and no Noteholder shall be responsible for the obligation or commitment of any other Noteholder hereunder. Nothing
contained in this Agreement and no action taken by the Noteholders pursuant hereto shall be deemed to constitute the Noteholders to be a partnership, an association, a joint venture or any other kind of entity. 
  
 SECTION 10.13. Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

  
 SECTION 10.14. Independence of Covenants. All covenants
hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or would otherwise be within the limitations of, another
covenant shall not avoid the occurrence of an Event of Default if such action is taken or condition exists. 
  
 SECTION 10.15. Subordination. THE OBLIGATIONS EVIDENCED HEREBY ARE SUBORDINATE IN THE MANNER AND TO THE EXTENT SET FORTH IN THAT CERTAIN
INTERCREDITOR AND SUBORDINATION AGREEMENT (THE “SUBORDINATION AGREEMENT”) DATED AS OF SEPTEMBER 14, 2004, AMONG SENIOR AGENT, BROWN BROTHERS HARRIMAN & CO., AS COLLATERAL AGENT FOR THE SENIOR LENDERS, AGENT, AND THE COMPANY, TO THE

officers thereunto duly authorized, as of the date first above written.

 FOR VALUE RECEIVED, the undersigned, SeraCare Life Sciences, Inc. (the “Company”) hereby promises to pay
to                      or registered assigns (the “Holder or “Noteholder”), the principal sum of
                                     Dollars
($                    ), with interest thereon, on the terms and conditions set forth in that certain Subordinated Note Agreement dated as of
September 14, 2004 among the Company, the Noteholder and David Barrett Inc. as Administrative Agent for the Noteholder (as the same may be amended, modified, extended, supplemented, superceded or restated, the “Note Agreement”).

  
 Payments of principal of, interest on and any premium with
respect to this Note are to be made in lawful money of the United States of America by check mailed and addressed to the registered Holder hereof at the address shown in the register maintained by the Issuers for such purpose, or, at the option of

 Notwithstanding any provision to the contrary in this Note, the Note Agreement or any other agreement,
the Issuers shall not be required to pay, and the Holder shall not be permitted to contract for, take, reserve, charge or receive, any compensation which constitutes interest under applicable law in excess of the maximum amount of interest permitted

 If at any time

under this Note is less than the Maximum Lawful Rate, the Issuers shall continue to pay interest under this Note at the Maximum Lawful Rate until such time as the total interest paid by the Issuers is equal to the total interest that would have been
paid had applicable law not limited the interest rate payable under the Note. 
  
 This Note is one of a series of Notes (herein called the “Notes”) issued pursuant to the Note Agreement and is entitled to the benefits thereof. All terms used herein shall have the meanings ascribed to them

 This Note is also subject to optional prepayment, in whole or in part at the
times and on the terms specified in the Note Agreement, but not otherwise. 
  
 If an Event of Default as defined in the Note Agreement occurs and is continuing, the unpaid principal of this Note may be declared or otherwise become due and payable in the manner, at the price (including any
applicable premium) and with the effect provided in the Note Agreement. 
  
 Payments of principal, interest on and any premium with respect to this Note and all Obligations of the Issuers under the Note Agreement are guarantied by the Parent pursuant to the Note Agreement. 
  
 The Company hereby unconditionally waives any and all right to presentment,
demand, protest or (except as expressly required hereby or by the Note Agreement) notice of any kind and any defenses to payment and/or any rights to setoff payment that the Company may have against the Holder or any other person, including any
person who assigned this Note to the Holder. 
  
 This Note and the
rights and obligations of the parties hereto shall be deemed to be contracts under the laws of the State of California and for all purposes shall be governed by and construed and enforced in accordance with the laws of said State, except for its
rules relating to the conflict of laws.
