 ACTS AND DUTIES OF SECURED CREDITORS 
  
 Section 2.1 Acts of Secured Creditors. Any request, demand,
authorization, direction, notice, consent, waiver or other action permitted or required by this Agreement to be given or taken by the Secured Creditors or any group constituting less than all Secured Creditors (including the Majority Secured
Creditors) may be and, at the request of the Collateral Agent, shall be embodied in and evidenced by one or more instruments signed by or on behalf of such Persons and, except as otherwise expressly provided in any such instrument, any such action
shall become effective when such instrument or instruments shall have been delivered to the Collateral Agent. The instrument or instruments evidencing any action (and the action embodied therein and evidenced thereby) are sometimes referred
to herein as an “Act” of the Persons 
  

 11. 

 signing such instrument or instruments. The Collateral Agent shall be entitled to rely absolutely upon an Act of
any Secured Creditor if such Act purports to be taken by or on behalf of such Secured Creditor, and nothing in this Section 2.1 or elsewhere in this Agreement shall be construed to require any Secured Creditor to demonstrate that it has been
authorized to take any action which it purports to be taking, the Collateral Agent being entitled to rely conclusively, and being fully protected in so relying, on any Act of such Secured Creditor. 
  
 Section 2.2 Determination of Amounts of Obligations. Whenever the
Collateral Agent is required to determine the existence or amount of any of the Secured Obligations or any portion thereof, or the existence of any Enforcement Event for any purposes of this Agreement, it shall be entitled to make such determination
on the basis of the Certificates Regarding Obligations, Notices of Enforcement Event, notices rescinding Notices of Enforcement Event, and other notices and certificates delivered to it by the Secured Creditors. The Collateral Agent may rely
conclusively, and shall be fully protected in so relying, on any determination made by it in accordance with the provisions of the preceding sentence (or as otherwise directed by a court of competent jurisdiction) and shall have no liability to the
Company, the other Credit Parties, any Secured Creditor or any other Person as a result of any action taken by the Collateral Agent based upon such determination prior to receipt of notice of any error in such determination. 
  
 Section 2.3 Restrictions on Actions. Each Secured Creditor agrees
that, after the occurrence and during the continuance of an Enforcement Event and until payment in full of the Secured Obligations, (i) the provisions of this Agreement shall govern exclusively the method by which the Collateral Agent or any Secured
Creditor may exercise rights and remedies under the Collateral Documents or otherwise with respect to the Collateral and (ii) except as expressly permitted hereunder, each Secured Creditor shall: 
  
 (a) refrain from taking or filing any action, judicial or otherwise,
to enforce rights or pursue any remedies under any of the Collateral Documents, except for delivering notices hereunder; 
  
 (b) refrain from exercising any rights or remedies (including the remedy of self-help) under any of the Collateral Documents which may be
exercisable as a result of an Enforcement Event; and 
  
 (c)
refrain from exercising any right of setoff, bankers’ lien or similar right with respect to amounts on deposit with such Secured Creditor (excluding application of funds pursuant to non-default contract rights); 
  
 provided, however, that the foregoing shall not prevent a Secured Creditor from
raising any defenses in any action in which it has been made a party defendant or has been joined as a third party, except that the Collateral Agent may direct and control any defense directly relating to the Collateral or the any of the Collateral
Documents, subject to and in accordance with the provisions of this Agreement. 
  
 Section 2.4 Notice of Enforcement Event; Other Notices. Each Secured Creditor shall, upon learning of the existence of any Enforcement Event under a Creditor Document to which it is a party, promptly deliver
written notice thereof describing in reasonable detail the 
  

 12. 

 nature of the event giving rise to such Enforcement Event and setting forth the date of occurrence of such event (a
“Notice of Enforcement Event”) to the Collateral Agent. Each Notice of Enforcement Event shall be deemed to have been given when such notice has actually been received by the Collateral Agent and to have been rescinded when
the Collateral Agent has received a certificate from Secured Creditors entitled to waive such default under the terms of the applicable Creditor Document and this Agreement stating that the events of default giving rise to such Enforcement Event
have been cured or waived in accordance with the terms of the applicable Creditor Document. A Notice of Enforcement Event shall be deemed to be outstanding at all times after such notice has been given until such time, if any, as such notice
has been rescinded. 
  
 ARTICLE III 
  
 DUTIES OF COLLATERAL AGENT 
  
 Section 3.1 Notices to Secured Creditors. The Collateral Agent
promptly, and in any event within 3 Business Days of its receipt thereof, shall deliver written notification to each Secured Creditor of the Collateral Agent’s receipt of any Notice of Enforcement Event from any Secured Creditor in accordance
with Section 2.4 (and the Collateral Agent shall provide each Secured Creditor a copy thereof), a certificate rescinding such Notice of Enforcement Event in accordance with Section 2.4, or any request by any party hereto or by the Company or any
other Credit Party for any consent, waiver or amendment with respect hereto or any other Creditor Document. 
  
 Section 3.2 Directions from Majority Secured Creditors. 
  

(a) Subject to the provisions of Article V, the Collateral Agent agrees to administer the Collateral Documents and the Collateral, to make such
demands, give such notices, take such actions under or with respect to the Collateral Documents and exercise other rights, powers and remedies as shall be available to it under the Collateral Documents (including, at any time when a Notice of
Enforcement Event shall have been given and shall be outstanding, the disposition of Collateral or any portion thereof) which are requested in writing by the Majority Secured Creditors (or, if permitted by this Section 3.2(a), the Minority Creditor
Group) and which are not inconsistent with or contrary to the provisions of this Agreement or the Collateral Documents or law. If at any time of determination (1) a Payment Default in respect of the Secured Obligations of each of the Secured
Creditors comprising a Minority Creditor Group has occurred and continued for at least 90 days and (2) during such period the Majority Secured Creditors shall not have directed the Collateral Agent to commence the exercise of remedies available to
it in respect of the Collateral, then the Minority Creditor Group shall thereafter, for so long as such Payment Default shall continue to exist, have the right to direct the Collateral Agent to do the things expressly stated in the first sentence of
this Section 3.2(a) (the period during which such right is exercisable being referred to herein as the “Minority Creditor Group Exercise Period”); provided, however, that such right shall not be exercisable unless and until
the sixth Business Day after the Minority Creditor Group shall have delivered a notice (a “Notice of Intent to Exercise Remedies”) to each of the other Secured Creditors certifying that the conditions described in the preceding
clauses (1) and (2) of this sentence have been satisfied, stating that the Minority Creditor Group has elected to exercise such right commencing six 
  

 13. 

 Business Days after delivery of such notice and describing in reasonable detail the actions intended to be pursued;
provided, further, that if, during the five Business Day period after delivery of such notice, any of such other Secured Creditors (“Joining Secured Creditor(s)”) deliver a written notice to the senders of such Notice of
Intent to Exercise Remedies that they will join in the commencement of the exercise of remedies then available to the Collateral Agent in respect of the Collateral and if the Principal Obligations of the Secured Obligations attributable to
the Minority Creditor Group together with the Principal Obligations of the Secured Obligations of the Joining Secured Creditor(s) constitutes the Majority Secured Creditors, then all actions expressly stated in the first sentence of this Section
3.2(a) shall thereafter require the direction of the Majority Secured Creditors. 
  
 (b) Absent written instructions from the Majority Secured Creditors (or, if permitted by Section 3.2(a), the Minority Creditor Group) at a time when a Notice of Enforcement Event shall be outstanding, the
Collateral Agent may take, but shall have no obligation to take, any and all such actions under the Collateral Documents or otherwise as it shall deem to be in the best interests of the Secured Creditors in order to maintain the Collateral and
protect and preserve the Collateral and the rights of the Secured Creditors; provided, however, that in the absence of written instructions (which may relate to the exercise of specific remedies or to the exercise of remedies in general) from
the Majority Secured Creditors (or, if permitted by Section 3.2(a), the Minority Creditor Group), the Collateral Agent shall not liquidate or compromise any claims under any of the Collateral Documents, make any disposition of the Collateral or
exercise any other remedies available to it under any of the Collateral Documents (other than insuring the Collateral) with respect to the Collateral or any part thereof. 
  
 (c) The Collateral Agent shall not be obligated to take any action under this Agreement or the Collateral Documents
except for the performance of such duties as are specifically set forth herein or therein.

 OTHER AMOUNTS RECEIVED 
  
 Section 4.1 Establishment of Collateral Accounts; Application of Proceeds of Collateral. 
  
 (a) Establishment of Collateral Accounts. The Collateral Agent shall
establish and maintain at its banking office in Portland, Oregon, (or upon written notice to the Secured Creditors, such other banking office in the State of Oregon as it may select, so long as its lien is continuously maintained as contemplated
herein) the following segregated account(s): 
  
 (i) an
account entitled the “Northwest Pipe Company Intercreditor Disbursement Account” (the “Intercreditor Disbursement Account”); and 
  
 (ii) an account entitled the “Northwest Pipe Company L/C Holding Account” (the “L/C Holding Account”). 
  

 14. 

 Each such account will be held by the Collateral Agent as provided in this Agreement and shall at all times be in the
exclusive possession of, and under the exclusive control of, the Collateral Agent, as agent for the Secured Creditors. Neither the Company, any other Credit Party nor any subsidiary of the Company or such other Credit Party shall have rights
to any such account or to any amounts on deposit therein, except the right to receive amounts, if any, in accordance with clause FOURTH of Section 4.1(d). Each of the Company and the other Credit Parties hereby grants and assigns to the
Collateral Agent, for the benefit of the Secured Creditors, as collateral security for the Secured Obligations, all of the Company’s or such other Credit Party’s right, title and interest in and to the Collateral Accounts, all funds from
time to time maintained therein, all investments thereof, all interest, dividends and other amounts earned thereon and all proceeds thereof.

as promptly as practicable, after receipt of a Notice of Enforcement Event, deposit into the Intercreditor Disbursement Account all amounts received by it in its capacity as Collateral Agent (and not in any other capacity) in respect of the Secured

Collateral pursuant to the Collateral Documents, any amounts turned over to the Collateral Agent pursuant to Section 4.4, and any distributions, adequate protection payments or similar amounts received in respect of the Collateral or otherwise in
any insolvency case or proceeding involving the Company or any other Credit Party.

all such deposits during such month to each Secured Creditor (a “Deposit Notice”), specifying (i) the dates of such deposits, (ii) the amounts of such deposits and (iii) the date on which the Collateral Agent will make a
disbursement in respect of such deposits (which date shall be a Business Day not less than ten (10) nor more than thirty (30) days after the date of the Deposit Notice (the “Disbursement Date”)). 
  
 (d) Disbursements to Secured Creditors and L/C Holding Account. On the
applicable Disbursement Date, the Collateral Agent shall disburse the amount on deposit in the Intercreditor Disbursement Account (the “Disbursement Amount”) in accordance with the order of priority set forth in clauses FIRST
through FIFTH below:

made, incurred or suffered by the Collateral Agent and its agents and counsel, including amounts required to be provided to the Collateral Agent pursuant to Section 4.1(f) in connection therewith or in connection with this Agreement or the
Collateral Documents; 
  
 SECOND: after
payment in full of the obligations described in Section 4.1(d) FIRST, then to the Secured Creditors in payment of any and all amounts owed to the 
  

 15. 

 Secured Creditors for reimbursement of amounts paid by them to the Collateral Agent (other than Exclusive
Indemnification Payments) in accordance with the indemnification provisions of Section 5.5 and Section 5.10, pro rata in proportion to their respective shares of such amount; 
  
 THIRD: after payment in full of the obligations described in Section 4.1(d) FIRST and SECOND, then to
(i) the Secured Creditors in payment of the Secured Obligations other than the L/C Exposure, if any, and (ii) the L/C Holding Account for the cash collateralization of the L/C Exposure; the amounts of such payment to Secured Creditors and
deposits into the L/C Holding Account to be made pro rata in proportion to the respective amounts of such Secured Obligations as determined by the Collateral Agent pursuant to Section 4.5; 
  
 FOURTH: after payment in full of the obligations
described in Section 4.1(d) FIRST, SECOND and THIRD, then to the Secured Creditors in payment of any and all amounts owed to any Secured Creditors for reimbursement of Exclusive Indemnification Payments, pro rata in proportion to their
respective shares of such amount; and 
  
 FIFTH: after payment or cash collateralization in full of the obligations described in Section 4.1(d) FIRST, SECOND, THIRD and FOURTH, then to the payment to or upon the order of the Company or to whomsoever may be lawfully entitled
to receive the same or as a court of competent jurisdiction may direct, of any surplus then remaining in the Intercreditor Disbursement Account. 
  
 Together with the payment of each disbursement from the Intercreditor Disbursement Account on each Disbursement Date, the Collateral Agent shall deliver to each Secured
Creditor a statement detailing the aggregate amount disbursed to all Secured Creditors, the amount deposited in each Collateral Account and all deductions therefrom pursuant to Section 4.1(d) FIRST and SECOND. 
  
 (e) Disbursements From L/C Holding Account. All amounts deposited in
the L/C Holding Account shall be deemed to be allocated to each Letter of Credit taken into account in the determination of the amount of such deposit, ratably in accordance with the respective maximum amounts available to be drawn under all such
Letters of Credit (the amount so allocated to a Letter of Credit being referred to as its “Allocable L/C Share”). At such time as (i) any such Letter of Credit expires undrawn or (ii) the amount available to be drawn under
any such Letter of Credit is irrevocably reduced (other than by a draw thereon) according to the terms thereof, in either case causing a reduction in the L/C Exposure, then the Allocable L/C Share attributable to such expired Letter of Credit or
such reduction in the L/C Exposure shall be deposited into the Intercreditor Disbursement Account and shall be distributed in accordance with Section 4.1(d). At such time as any such Letter of Credit is drawn, the Allocable L/C Share
attributable to such Letter of Credit shall be disbursed from the L/C Holding Account by the Collateral Agent to the Issuing Bank. 
  
 (f) Collateral Agent’s Costs and Expenses. The Collateral Agent shall have the right at any time and from time to time, after delivery to each
Secured Creditor of a written accounting, to apply any amounts in the Intercreditor Disbursement Account to the payment of

 the fee set forth in Section 5.2 and the reasonable out-of-pocket costs and expenses (including reasonable attorney fees
and disbursements) incurred by the Collateral Agent in administering and carrying out its obligations under this Agreement or the Collateral Documents, in exercising or attempting to exercise any right or remedy hereunder or thereunder or in taking
possession of, protecting, preserving or disposing of any item of Collateral, and all amounts against or for which the Collateral Agent is to be indemnified or reimbursed hereunder (excluding any such costs, expenses or amounts which have
theretofore been reimbursed) until all of such costs, expenses and amounts have been paid in full. 
  
 Section 4.2 Investment of Amounts in Collateral Accounts. Pending the disbursement thereof pursuant to the terms of this Agreement, all amounts in
the Collateral Accounts shall (to the extent practical under the circumstances) be invested by the Collateral Agent in Permitted Investments. The Collateral Agent shall endeavor to select Permitted Investments for each Collateral Account that
mature prior to the anticipated date of any distribution to be made from such Collateral Account. The Collateral Agent shall have no liability for any losses resulting from the investment of amounts in the Collateral Accounts pursuant to this
Section 4.2 to the extent that such investments are made and maintained solely in Permitted Investments. 
  
 Section 4.3 Turnover of Collateral Received by Secured Creditors. Each Secured Creditor promptly shall, after the occurrence and during the
continuance of an Enforcement Event, put in the custody, possession or control of the Collateral Agent for disposition or distribution in accordance with the provisions of Section 4.1 any Collateral or proceeds thereof over which such Secured
Creditor obtains custody, control or possession. Until such time as each Secured Creditor shall have complied with the provisions of the immediately preceding sentence, such Secured Creditor shall be deemed to hold such Collateral or proceeds
in trust for the parties entitled thereto hereunder. 
  
 Section 4.4 Turnover of Deemed Collateral Proceeds by Secured Creditors. The Secured Creditors hereby agree among themselves that if an Enforcement Event shall occur and at any time during the continuation of such Enforcement Event
any of them shall receive any Deemed Collateral Proceeds, then the Secured Creditor receiving such Deemed Collateral Proceeds shall as promptly as practicable turn over such proceeds to the Collateral Agent for distribution in accordance with
Section 4.1(d). Each of the Company and the other Credit Parties expressly consents to the foregoing arrangement and agrees that any amount so turned over by any Secured Creditor will be deemed to have been received by the Collateral Agent and the
Secured Creditors that ultimately receive such amount such that, if such amount turned over has previously reduced the claim of the Secured Creditor turning over such amount, (i) the amount of the claim against the Company and the other Credit
Parties of the Secured Creditor that turns over such amounts shall immediately be increased to the extent such amounts are turned over to the Collateral Agent and (ii) the amount of the claims of the Collateral Agent and each Secured Creditor that
ultimately receives any portion of such amount shall immediately be decreased to the extent of the amount received by it. 
  
 Section 4.5 Determination of Pro Rata Shares. Not later than five (5) Business Days after each Secured Creditor’s receipt from the Collateral
Agent pursuant to Section 3.1 of the notice of the occurrence of an Enforcement Event, such Secured Creditor shall deliver to the 
  

 17. 

 Collateral Agent and each other Secured Creditor a duly completed Certificate Regarding Obligations which shall certify
(i) the amount of Secured Obligations (separately stating the Principal Obligations (including any L/C Exposure), Make-Whole Amounts, Yield-Maintenance Amounts, LIBOR breakage costs under the Loan Documents and interest) due and payable to such
Secured Creditor at the time of occurrence of the Enforcement Event specified in such notice and (ii) the aggregate amount of any Deemed Collateral Proceeds received by such Secured Creditor on or after the occurrence of the Enforcement Event
specified in such notice (and such Secured Creditor shall turn over such Deemed Collateral Proceeds in accordance with the requirements of Section 4.4). The Collateral Agent shall calculate, in reliance upon such certificates, the Pro Rata Shares of
each of the Secured Creditors and the aggregate amount of Deemed Collateral Proceeds received by all Secured Creditors since the applicable Enforcement Event. Promptly following its determination of such Pro Rata Shares and in any event no later
than the tenth (10th) Business Day following the applicable Enforcement Event, the Collateral Agent shall notify the
Secured Creditors in writing of such determinations. Subject only to manifest error, the Pro Rata Shares shall be fixed and not be recalculated. 
  
 Section 4.6 Adjustment for Avoided Payments. Each party hereto agrees that, in the event any payment of any of the Secured Obligations made to any
party hereto which has been turned over and distributed hereunder is subsequently invalidated, declared fraudulent or preferential, set aside or required to be paid to a trustee, receiver, or any other party under any bankruptcy act, state or
federal law, common law or equitable cause (“Avoided Payments”), the other parties shall pay to such party such amounts so that, after giving effect to such payments by all such other parties, the amounts received by all parties are
not in excess of the amounts which would have been paid to them hereunder if such Avoided Payments had not been made. 
  
 ARTICLE V 
  
 CONCERNING THE COLLATERAL AGENT 
  
 Section 5.1 Appointment and Authorization of Collateral Agent. Each Secured Creditor hereby appoints, designates and authorizes Wells Fargo as the initial Collateral Agent to (i) hold as a representative (as

on such Secured Creditor’s behalf under the provisions of this Agreement and each Collateral Document and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Agreement or any
Collateral Document, together with such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere herein or in any Collateral Document, (1) the Collateral Agent shall not have any duties or
responsibilities, except those expressly set forth herein or in a Collateral Document, and (2) no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any Collateral Document or
otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” herein and in the other Collateral Documents with reference to the Collateral Agent is not intended to
connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only a collateral relationship
between independent contracting parties. 
  

 18.

the Collateral Agent for its own account (i) a fee in the amount of $2,500 per calendar month plus (ii) the Collateral Agent’s actual out-of-pocket expenses in serving as Collateral Agent under this Agreement. Such monthly fee shall be due and

 Section 5.3 Delegation of Duties. The Collateral Agent may execute any

 Section 5.4 Liability of Collateral Agent. No Agent-Related Person shall (a) be liable for any action taken or omitted to be taken by any of them
under or in connection with this Agreement or any Collateral Document or the transactions contemplated hereby (except for its own gross negligence or willful misconduct in connection with its duties expressly set forth herein), or (b) be responsible
in any manner to any Secured Creditor or participant for any recital, statement, representation or warranty made by any Credit Party or any officer thereof, contained herein or in any Collateral Document, or in any certificate, report, statement or
other document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Agreement or any Collateral Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement
or any Collateral Document, or for any failure of any Credit Party, Secured Creditor or any other party to any Collateral Document to perform its obligations hereunder or thereunder. No Agent-Related Person shall be under any obligation to any
Secured Creditor to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any Collateral Document, or to inspect the properties, books or records of any Credit Party or
any Affiliate thereof. 
  
 Section 5.5 Reliance by Collateral
Agent. The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex

counsel (including counsel to any Credit Party), independent accountants and other experts selected by the Collateral Agent. The Collateral Agent shall be fully justified in failing or refusing to take any action under any Collateral Document unless
it shall first receive such advice or concurrence of the Majority Secured Creditors (or such greater number of Secured Creditors as may be expressly required hereby in any instance or, if permitted by Section 3.2(a), the Minority Creditor Group) as
it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Secured Creditors against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action.
The Collateral Agent shall in all cases be 
  

 19. 

 fully protected in acting, or in refraining from acting, under this Agreement or any Collateral Document in accordance
with a request or consent of the Majority Secured Creditors (or such greater number of Secured Creditors as may be expressly required hereby in any instance or, if permitted by Section 3.2(a), the Minority Creditor Group) and such request and any
action taken or failure to act pursuant thereto shall be binding upon all the Secured Creditors. 
  
 Section 5.6 Notice of Enforcement Event. The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Enforcement
Event, unless the Collateral Agent shall have received written notice from a Secured Creditor in accordance with Section 2.4. The Collateral Agent shall take such action with respect to such Enforcement Event as may be directed by the Majority
Secured Creditors in accordance with Section 3.2 or, if permitted by Section 3.2(a), as may be directed by the Minority Creditor Group. 
  
 Section 5.7 Credit Decision; Disclosure of Information by Collateral Agent. Each Secured Creditor acknowledges that, except as set forth in Article
6 hereof, no Agent-Related Person has made any representation or warranty to it, and that no act by the Collateral Agent hereafter taken shall be deemed to constitute any representation or warranty by any Agent-Related Person to any Secured Creditor
as to any matter, including whether Agent-Related Persons have disclosed material information in their possession. Each Secured Creditor represents to the Collateral Agent and the other Secured Creditors that it has, independently and without
reliance upon any Agent-Related Person or any other Secured Creditor and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial
and other condition and creditworthiness of the Credit Parties and their respective direct or indirect subsidiaries, and all applicable bank or other regulatory laws relating to the transactions contemplated hereby, and made its own decision to
extend credit to the Credit Parties. Each Secured Creditor also represents that it will, independently and without reliance upon any Agent-Related Person or any other Secured Creditor and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the Collateral Documents, and to make such investigations as it deems necessary to inform itself as
to the business, prospects, operations, property, financial and other condition and creditworthiness of the Company and the other Credit Parties. Except for notices, reports and other documents expressly required to be furnished to the Secured
Creditors by the Collateral Agent herein, the Collateral Agent shall not have any duty or responsibility to provide any Secured Creditor with any credit or other information concerning the business, prospects, operations, property, financial and
other condition or creditworthiness of any of the Credit Parties or any of their respective Affiliates which may come into the possession of any Agent-Related Person. 
  
 Section 5.8 Attorney Costs, Expenses and Taxes. By countersigning this Agreement the Company and each other Credit
Party agrees (a) to pay or reimburse the Collateral Agent for all costs and expenses, including reasonable attorneys’ fees and disbursements (including allocated costs of in-house counsel), incurred in connection with the preparation,
negotiation and execution of this Agreement and the Collateral Documents and any amendment, waiver, consent or other modification of the provisions hereof and thereof (whether or not the transactions contemplated hereby or thereby are consummated),
and the consummation and administration of the transactions contemplated hereby and thereby, and (b) to pay or reimburse the Collateral 
  

 20. 

 Agent for all costs and expenses, including reasonable attorneys’ fees and disbursements (including allocated costs
of in-house counsel), incurred in connection with the enforcement, attempted enforcement, or preservation of any rights or remedies under this Agreement or the Collateral Documents (including all such costs and expenses incurred during any
“workout” or restructuring in respect of the Secured Obligations and during any legal proceeding, including any proceeding under any applicable bankruptcy, insolvency or other similar law affecting the rights of creditors generally of the
United States of America or any state thereof). The foregoing costs and expenses shall include all search, filing, recording, title insurance and appraisal charges and fees and taxes related thereto, and other out-of-pocket expenses incurred by the
Collateral Agent and the cost of independent public accountants and other outside experts retained by the Collateral Agent in connection with the matters described in this Section 5.8. All amounts due under this Section shall be payable within ten
Business Days after demand therefor. The agreements in this Section shall survive the repayment of the Secured Obligations. 
  
 Section 5.9 Indemnification by Company. By countersigning this Agreement the Company and each other Credit Party agrees to indemnify upon demand
the Collateral Agent and its Affiliates, directors, officers, employees, counsel, agents and attorneys-in-fact (collectively the “Agent-Related Persons”) from and against any and all liabilities, obligations, losses, damages,
penalties, claims, demands, actions, judgments, suits, costs, expenses and disbursements, including attorneys’ fees and disbursements (including allocated costs of in-house counsel) of any kind or nature whatsoever which may at any time be
imposed on, incurred by or asserted against any such Agent-Related Person in any way relating to or arising out of or in connection with (a) the execution, delivery, enforcement, performance or administration of this Agreement, any Collateral
Document or any other agreement, letter or instrument delivered in connection with the transactions contemplated thereby or the consummation of the transactions contemplated thereby, (b) any Secured Obligation or the use or proposed use of the
proceeds therefrom, (c) any actual or alleged presence or release of Hazardous Materials on or from any property currently or formerly owned or operated by the Company, any of its direct or indirect subsidiaries or any other Credit Party, or any
Environmental Liability related in any way to the Company, any of its direct or indirect subsidiaries or any other Credit Party, or (d) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing,
whether based on contract, tort or any other theory (including any investigation of, preparation for, or defense of any pending or threatened claim, investigation, litigation or proceeding) and regardless of whether any Agent-Related Person is a
party thereto (all the foregoing, collectively, the “Indemnified Liabilities”), in all cases, whether or not caused by or arising, in whole or in part, out of the negligence of the Agent-Related Person; provided that such
indemnity shall not, as to any Agent-Related Person, be available to the extent that such liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses or disbursements are determined by a court of
competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Agent-Related Person. No Agent-Related Person shall be liable for any damages arising from the use by others of any
information or other materials obtained through IntraLinks or other similar information transmission systems in connection with this Agreement, nor shall any Agent-Related Person have any liability for any indirect or consequential damages relating
to this Agreement or any Collateral Document or arising out of its activities in connection herewith or therewith (whether before or after the date of this Agreement). All amounts due under this Section shall be payable within ten Business Days
after demand therefor. The agreements in this Section shall survive the resignation of the Collateral Agent and the repayment, satisfaction or discharge of the Secured Obligations. 
  

 21. 

 Section 5.10 Indemnification by Secured Creditors. The Secured Creditors shall indemnify upon
demand each Agent-Related Person (to the extent not reimbursed by or on behalf of any Credit Party and without limiting the obligation of any Credit Party to do so) in their respective Pro Rata Shares and hold harmless each Agent-Related Person from
and against any and all Indemnified Liabilities incurred by it; provided, however, that no Secured Creditor shall be liable for the payment to any Agent-Related Person of any portion of such Indemnified Liabilities to the extent such
portion resulted from such Agent-Related Person’s own gross negligence or willful misconduct; provided, however, that no action taken in accordance with the directions of the Majority Secured Creditors or the directions of a
Minority Creditor Group during a Minority Creditor Group Exercise Period shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section. Without limitation of the foregoing, each Secured Creditor shall reimburse
the Collateral Agent upon demand for its Pro Rata Share of any costs or out-of-pocket expenses, including reasonable attorneys’ fees and disbursements (including allocated costs of in-house counsel), incurred by the Collateral Agent in
connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this
Agreement, the Collateral Documents or any other document contemplated by or referred to herein, in each case to the extent that the Collateral Agent is not reimbursed for such expenses by the Company or the other Credit Parties. Notwithstanding
anything to the contrary in this Section 5.10, if a Minority Creditor Group Exercise Period shall have commenced, then the indemnification obligations described in this Section 5.10 that are incurred from actions taken by or at the direction of the
applicable Minority Creditor Group during the effectiveness of such Minority Creditor Group Exercise Period shall be solely obligations of such Minority Creditor Group. The agreements in this Section shall survive the resignation of the Collateral
Agent and the repayment, satisfaction or discharge of the Secured Obligations. 
  
 Section 5.11 Wells Fargo in its Individual Capacity. Wells Fargo and its Affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally
engage in any kind of banking, trust, financial advisory, underwriting or other business with each of the Credit Parties and their respective Affiliates as though Wells Fargo were not the Collateral Agent hereunder and without notice to or consent
of the Secured Creditors. The Secured Creditors acknowledge that, pursuant to such activities, Wells Fargo or its Affiliates may receive information regarding any Credit Party or its Affiliates (including information that may be subject to
confidentiality obligations in favor of such Credit Party or such Affiliate) and acknowledge that the Collateral Agent shall be under no obligation to provide such information to them. With respect to its Secured Obligations, Wells Fargo shall have
the same rights and powers under this Agreement as any other Secured Creditor and may exercise such rights and powers as though it were not the Collateral Agent, and the terms “Credit Agreement Lender” and “Secured Creditor”
include Wells Fargo in its individual capacity. 
  
 Section
5.12 Successor Collateral Agent. The Collateral Agent may resign at any time by giving thirty (30) days’ written notice thereof to the Secured Creditors and may be removed at any time with or without cause by the Majority Secured Creditors.
Upon any such 
  

 22. 

 resignation or removal, the Majority Secured Creditors shall have the right to appoint a successor Collateral Agent. If
no successor Collateral Agent shall have been appointed by the Majority Secured Creditors and shall have accepted such appointment within thirty (30) days after the retiring Collateral Agent’s giving of notice of resignation or the Majority
Secured Creditors’ removal of the retiring Collateral Agent, then the retiring Collateral Agent may, on behalf of the Secured Creditors, appoint a successor Collateral Agent, which shall be a state or national bank, trust company or insurance
company organized under the laws of the United States of America or of any state thereof and having a combined capital and surplus of at least $200,000,000. Upon the acceptance of any appointment as Collateral Agent hereunder by a successor
Collateral Agent, (i) the retiring Collateral Agent shall assign all of the security interests in, mortgages and other liens upon all Collateral under the Collateral Documents, and all right, title and interest of the retiring Collateral Agent under
the Collateral Documents, to the replacement Collateral Agent, without recourse or representation or warranty by the retiring Collateral Agent or any Secured Creditors and at the expense of the Company, and (ii) such successor Collateral Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent, and the retiring Collateral Agent shall be discharged from its duties and obligations hereunder and under the Collateral
Documents. After any retiring Collateral Agent’s resignation or removal hereunder as Collateral Agent, the provisions of this Article V shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while
it was acting as Collateral Agent. Notwithstanding anything to the contrary in this Section 5.12, no resignation or removal of the Collateral Agent shall become effective until a replacement Collateral Agent shall have been selected as provided
herein and shall have assumed in writing the obligations of the Collateral Agent under this Agreement and the Collateral Documents. 
  
 ARTICLE VI

amend, modify or waive any term, condition, covenant or provision of the Creditor Documents to which such Secured Creditor is a party. 
  
 Section 7.3 Release of Collateral. The Collateral Agent is authorized hereby to execute releases of liens with respect to property of the Company
or the other Credit Parties to the extent that the sale, transfer or other disposition thereof is not prohibited by the terms of the Credit Agreement, the Prudential Note Agreement, the 1997 Note Agreement, the 1998 Note Agreement or any other
Creditor Document. 
  
 Section 7.4 Additional Guarantors and
Collateral. Each of the Secured Creditors hereby covenants and agrees that it will not, except for the IDB Documents, (i) accept any guaranty of any of the Secured Obligations by any subsidiary of the Company or any other Person unless such

Documents for cash. In addition, any Secured Creditor may purchase Collateral at any public sale of such Collateral pursuant to the Collateral Documents and may make payment on account thereof by using any Secured Obligation then due and

otherwise would receive in a Bankruptcy Proceeding in the absence of this Agreement. 
  

 25. 

 (b) The Collateral Agent is not entitled to initiate such actions on behalf of any Secured
Creditor or to appear and be heard on any matter before the bankruptcy or other applicable court in any such proceeding as the representative of any Secured Creditor, unless such action or appearance has been approved in writing by such Secured

holder of Secured Obligations and to appear or be heard on any matter before the bankruptcy or other applicable court in any such proceeding. 
  
 Section 7.7 No Contest of Secured Obligations. Except for breaches of this Agreement, each Secured Creditor and the Collateral Agent agrees that it
will not at any time contest the validity or enforceability of the Secured Obligations, or any provisions of any of the Creditor Documents, or the validity, enforceability, perfection or priority of the liens and security interests of the Collateral
Agent in the Collateral securing the Secured Obligations. 
  
 Section 7.8 Further Assurances, Etc. Each party hereto shall execute and deliver such other documents and instruments, in form and substance reasonably satisfactory to the other parties hereto, and shall take such other action, in
each case as any other party hereto reasonably may have requested (at the cost and expense of the Company which, by countersigning this Agreement, agrees to pay such costs and expenses), to effectuate and carry out the provisions of this Agreement,
including by recording or filing in such places as the requesting party may deem desirable, this Agreement or such other documents or instruments. 
  
 ARTICLE VIII 
  
 MISCELLANEOUS 
  
 Section 8.1 No Individual Action. No Secured Creditor may require the Collateral Agent to take any action hereunder or under the Collateral Documents or with respect to any of the Collateral except as and to
the extent expressly set forth in this Agreement. 
  
 Section
8.2 Successors and Assigns; Replacements and Refinancings. Except as provided in the second succeeding sentence, none of the Secured Creditors shall assign or transfer any interest in the Secured Obligations held by it unless such Secured
Creditor shall have caused the assignee or transferee to execute and deliver to each other Secured Creditor, concurrent with the effectiveness of such assignment or transfer, a Joinder Agreement (Secured Creditor). Any of the Secured Obligations may
be replaced or refinanced and the lender(s) replacing or refinancing such Secured Obligations will become a party hereto as a Secured Creditor(s) with respect to the indebtedness to be provided by it to replace or refinance such Secured Obligations
if the lender replacing or refinancing such Secured Obligations executes and 
  

 26. 

 delivers to each other Secured Creditor a Joinder Agreement (Secured Creditor). Any Secured Creditor may, without the
consent of any other Secured Creditor, sell one or more participations in any portion of the Secured Obligations held by such Secured Creditor; provided, however, that (except as otherwise specified herein) each Secured Creditor shall remain
liable to each other Secured Creditor for the full performance of its obligations hereunder with the same effect as though no such participation had been sold and as though any and all amounts, payments or security received by a participant with
whom it dealt in respect of the loan or note participation were received by such party and shall continue to deal solely and directly with each other with respect to their respective rights and obligations under this Agreement. PIM shall
cause any Prudential Affiliate that becomes an initial holder of Prudential Shelf Notes (if such Prudential Affiliate is not already a party to this Agreement) to execute and deliver a Joinder Agreement (Secured Creditor) concurrent with such
Prudential Affiliate’s becoming a holder of Prudential Shelf Notes. The Company agrees that, concurrent with any Person becoming a guarantor or other co-obligor of any portion of the Secured Obligations, it will cause such Person to execute and
deliver to each other party hereto a Joinder Agreement (Additional Credit Party). Except as provided in Section 8.6(b), this Agreement is not intended to confer any benefit on, or create any obligation of the Collateral Agent or any Secured Creditor
to, the Company, any other Credit Party or any third party. This Agreement shall be binding on each of the Company, the other Credit Parties and its successors and assigns. This Agreement shall be binding on and inure to the benefit of the
successors of each of the Secured Creditors. 
  
 Section 8.3
Notices. Notices and other communications provided for herein or in the Collateral Documents shall be in writing and shall be delivered by hand or overnight courier service, mailed or sent by facsimile to the parties hereto at the respective
addresses or facsimile numbers, as applicable, set forth below such parties’ names on the signature pages hereto or the Joinder Agreement (Secured Party) or Joinder Agreement (Additional Credit Party) pursuant to which such Persons become

been given on the date of receipt if delivered by hand or overnight courier service or sent by facsimile, or on the date three Business Days after dispatch by certified or registered mail if mailed, in each case delivered, sent or mailed (properly
addressed) to such party as provided in this Section 8.3 or, in each case, in accordance with the latest unrevoked direction from such party given in accordance with this Section 8.3. 
  
 Section 8.4 Termination. This Agreement and the agency of the Collateral Agent shall terminate automatically upon the
earlier of: (i) the final payment in full of the outstanding Secured Obligations; provided, however, that this Section 8.4 and Sections 5.8, 5.9, 5.10 and 8.5 of this Agreement shall survive, and remain operative and in full force and effect,
regardless of such termination; and (ii) in the event of any dissolution, winding up, liquidation, reorganization or other insolvency proceeding of the Company or any other Credit Party, the completion of all distributions from such proceedings to
the Secured Creditors in respect of the Secured Obligations after the discharge or satisfaction thereof, the satisfaction or discharge of the obligations under the Collateral Documents and the compliance with the provisions of this Agreement
(including those set forth in Section 4) with respect to all Deemed Collateral Proceeds and other property received by the Secured Creditors in respect of the Secured Obligations. 
  

 27. 

 Section 8.5 APPLICABLE LAW. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY
THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES. 
  
 Section 8.6 Amendments and Waivers of Agreement and Collateral Documents. No amendment, waiver or other modification of any provision of this Agreement or any of the Collateral Documents shall in any event be
effective unless the same shall be in writing and signed by the Majority Secured Creditors; provided, however, that: 
  
 (a) no such amendment or waiver shall adversely affect any of the Collateral Agent’s rights, immunities or rights to indemnification hereunder
or under the Collateral Documents or expand its duties hereunder or under the Collateral Documents without the prior written consent of the Collateral Agent; 
  
 (b) no such amendment or waiver of Sections 4.1(a), 4.4, 5.2, 5.8, 5.9, Article VI, Section 7.8 or Article VIII which affects the duties of the
Company or any other Credit Party shall be effective without the prior written consent of the Company; 
  
 (c) no such amendment or waiver shall modify any provision hereof which is intended to provide for the equal and ratable security of all Secured
Obligations without the prior written consent of all holders of Secured Obligations affected thereby; 
  
 (d) no such amendment or waiver that (i) decreases the portion of the Disbursement Amount that any Secured Creditor would receive pursuant to
Section 4.1(d), (ii) has the effect of rendering any Person no longer a Secured Creditor under this Agreement or the Collateral Documents or (iii) permits the release of the Company or any other Credit Party of any of its obligations under this
Agreement, shall be effective without the prior written consent of all Secured Creditors affected thereby; 
  
 (e) no such amendment or waiver shall change the definition of “Majority Secured Creditors” or modify this Section or Sections 3.2, 4.3,
4.4, 7.2 or 7.3 without the prior written consent of each Secured Creditor; and 
  
 (f) no such amendment or waiver of this Section 8.6 shall be effective without the prior written consent of all parties hereto. 
  
 No waiver of any provision of this Agreement and no consent to any departure by any party hereto from the provisions hereof shall be
effective unless such waiver or consent shall be set forth in a written instrument executed by the party against which it is sought to be enforced, and then such waiver or consent shall be effective only in the specific instance and for the purpose
for which given. No notice to or demand on any party hereto in any case shall entitle such party to any other or further notice or demand in the same, similar or other circumstances. 
  
 Section 8.7 Waiver of Rights. Neither any failure nor any delay on the part of any party hereto in exercising any
right, power or privilege hereunder shall operate as a waiver thereof, and a single or partial exercise thereof shall not preclude any other or further exercise or the exercise of any other right, power or privilege. 
  

 28. 

 Section 8.8 Severability. 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. The parties shall endeavor in good faith
negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provision. 
  
 Section 8.9 Counterparts; Effectiveness. This Agreement may be
executed in two or more counterparts, each of which shall constitute an original, but all of which, when taken together, shall constitute but one instrument. This Agreement shall become effective on the date (the “Closing

 Section 8.10 Section Headings. The Article and Section headings used herein are for convenience of reference only and
