provisions shall apply to the Collateral:





(a)  Each Debtor represents and warrants that it has and
will have good and marketable title to the Collateral from time to time owned or acquired by it, free and clear of all liens, encumbrances and security interests, except Permitted Liens. Each Debtor will take all reasonable steps to defend such
title against the claims and demands of all persons whomsoever.

warrants to the Lender that it does not currently own or hold any Documents, Instruments or Chattel Paper. In order to perfect the security interest granted by each Debtor hereby, each Debtor shall deliver to the Lender possession of any Documents,
Instruments and Chattel Paper hereafter acquired by such Debtor (duly endorsed by such Debtor in blank), promptly upon its acquisition of the same.





(c)  Except as may be permitted by the Credit Agreement, the Debtors will not (i) sell, lease, transfer or otherwise dispose of any of the
Collateral, (ii)borrow against the Collateral from any person, firm or corporation other than from the Lender pursuant to the Credit Agreement, (iii) create, incur, assume or suffer to exist any Lien on any of the

4




---

permit any notice to be filed under the Assignment of Claims Act with respect to any of the Collateral, except for any such notice in
favor of the Lender.





(d)  Risk of loss of, damage to or destruction of the Collateral is on the
Debtors. The Debtors will insure the Collateral against such risks and casualties and in such amounts and with such insurers as are specified in the Credit Agreement. All such policies of insurance shall contain loss payable clauses in favor of the
Debtors and the Lender as their respective interests may appear, and such policies or certificates evidencing the same shall be deposited with the Lender immediately upon the request of the Lender. Each Debtor agrees to notify the Lender promptly of
any notice of cancellation of any such policy and agrees not to cancel, mortgage, pledge, hypothecate, sell, transfer or assign its interest in any such insurance or any rights to cancel such insurance or to obtain the return of the unearned
premiums therefor to any person other than the Lender. If any Debtor fails to effect and keep in full force and effect such insurance or fails to pay the premiums thereon when due, the Lender may do so for the account of such Debtor and add the cost
thereof to the Debt, and the same shall be payable to the Lender on demand (unless it has obtained reasonably satisfactory substitute insurance policies prior to the Lenders obtaining such insurance). Each Debtor hereby assigns and sets over
unto the Lender all moneys which may become payable on account of such insurance, including, without limitation, any return of unearned premiums which may be due upon cancellation of any such insurance, and directs the insurers to pay the Lender any
amount so due. Following the occurrence and during the continuation of an Event of Default, the Lender, its officers, employees and authorized agents, are hereby irrevocably appointed attorneys-in-fact of each Debtor to endorse any draft or check
which may be payable to such Debtor in order to collect the proceeds of such insurance or any return of unearned premiums. Such proceeds shall be applied to the payment or prepayment of the Debt in such order as the Lender may determine In
accordance with the Credit Agreement. Any balance of insurance proceeds remaining in the possession of the Lender after payment in full of the Debt shall be paid to the Borrower or order.





(e)  Each Debtor assumes full responsibility for taking any and all necessary steps to preserve rights in respect of the Accounts, Chattel Paper, Contract
Rights, Instruments, Documents and General Intangibles against all account debtors, obligors and other persons.





(f)  Upon the occurrence and during the continuance of any Event of Default, each Debtor shall promptly upon demand by the Lender assemble the Equipment and Inventory and make it available to the Lender at the place or places to
be designated by the Lender which shall be reasonably convenient to all parties. The right of the Lender under this subsection (f) to have the Equipment and Inventory assembled and made available to it is of the essence of this Agreement




5




---

and the Lender may, at its election, enforce such right by a bill In equity for specific performance.





(g)  If any Debtor fails to maintain each item of Equipment and Inventory in accordance with the requirements specified in
the Credit Agreement, the Lender may pay the cost of such repairs or maintenance and such taxes, levies or other impositions for the account of such Debtor (and shall provide notice to such Debtor of such payments) and add the amount thereof to the
Debt, and the same shall be payable to the Lender on demand.





The Lender shall have no duty as to the collection or protection of the Collateral or any
part thereof or any income thereon, or as to the preservation of any rights pertaining thereto, beyond exercising reasonable care in the custody of any Collateral actually in the possession of the Lender. The Lender shall be deemed to have exercised
reasonable care in the custody and preservation of such of the Collateral as may be in its possession if it takes such action for that purpose as any Debtor shall request in writing, provided that such requested action shall not, in the judgment of
the Lender, impair the Lenders security interest in the Collateral or its rights in, or the value of, the Collateral, and provided further that such written request is received by the Lender in sufficient time to permit it to take the
requested action.





5.Certain Additional Matters.    Each Debtor represents, warrants,
covenants and agrees that:





(a)  This Agreement is effective to create in favor of the Lender for
the benefit of the Lender a legal, valid and enforceable security interest in all right, title and interest in and to the Collateral. When the financing statements indicated in the Perfection Certificate have been filed in the offices in the
jurisdictions listed in the Perfection Certificate, this Security Agreement will constitute a fully perfected Lien on, and security interest in and to, the Collateral, subject only to Permitted Liens, and prior to all other Liens. Each Debtor shall,
at its expense, promptly take any and all such other or further acts as the Lender may deem necessary or advisable to execute, acknowledge and deliver, and thereafter register, file or record, any document or instrument supplemental to or
confirmatory of this Agreement (including financing statements and continuation statements) which may be necessary or desirable to preserve, perfect and continue perfected the Lenders security interest in the Collateral, including, without
limitation, the signing of financing and other similar statements.





(b)  Each Debtor has previously
delivered to the Lender a certificate signed by such Debtor and entitled Perfection Certificate (the Perfection Certificate). Each Debtor represents and warrants to the Lender as follows: (i) such Debtors
exact legal name is that indicated on the Perfection Certificate and on the signature page hereof, (ii) such Debtor is an organization of the type and organized in the jurisdiction set forth in the Perfection Certificate, (iii) the

Perfection Certificate accurately sets forth such Debtors organizational identification number or accurately states that such
Debtor has none, (iv) the Perfection Certificate accurately sets forth such Debtors place of business or, if more than one, its chief executive office as well as such Debtors mailing address if different and (v) all other information set
forth on the Perfection Certificate pertaining to such Debtor is accurate and complete.





(c)  Each
Debtor covenants with the Lender as follows: (a) without providing at least 30 days prior written notice to the Lender, such Debtor will not change its name, its place of business or, if more than one, chief executive office, or its mailing address
or organizational identification number if it has one, or the locations of the Collateral from those listed on the Perfection Certificate, (b) if such Debtor does not have an organizational identification number and later obtains one, such Debtor
shall forthwith notify the Lender of such organizational identification number, and (c) such Debtor will not change its type of organization, jurisdiction of organization or other legal structure.





(d)  The Lender is hereby appointed attorney-in-fact for each Debtor to do all acts and things which the Lender may deem
necessary or advisable to preserve, perfect and continue perfected the Lenders security Interest in the Collateral.





(e)  Each Debtor hereby irrevocably authorizes the Lender at any time and from time to time to file in any UCC jurisdiction any initial financing statements and amendments thereto that (i) indicate the
Collateral (A) as all assets of such Debtor or words of similar effect, regardless of whether any particular asset comprised in the Collateral falls within the scope of Article 9 of the UCC, or (B) as being of an equal or lesser scope or with
greater detail, and (ii) contain any other information required by part 5 of Article 9 of the UCC for the sufficiency or filing office acceptance of any financing statement or amendment, including (A) whether such Debtor is an organization, the type
of organization and any organization identification number issued to such Debtor and, (B) in the case of a financing statement filed as a fixture filing or indicating Collateral as as-extracted collateral or timber to be cut, a sufficient
description of real property to which the Collateral relates. Each Debtor agrees to furnish any such information to the Lender promptly upon request.





6.Cash Management.





(a)  Each Debtor will
deposit, or cause to be deposited, all Items of Payment to a bank account designated by the Lender and from which the Lender alone has power of access and withdrawal (the Collateral Account). Each deposit shall be made not
later than the next Business Day after the date of receipt of the Items of Payment. The Items of Payment shall be deposited in precisely the form received, except for the endorsements of such Debtor where necessary to permit the collection of any
such Items of Payment, such Debtor hereby agreeing




7




---

to make such endorsement. In the event such Debtor shall fail to do so, the Lender is hereby authorized by such Debtor to make the
endorsement in the name of such Debtor. Prior to such a deposit, such Debtor will not commingle any Items of Payment with any of the other funds or property of such Debtor, but will hold them separate and apart in trust and for the account of the
Lender.





(b)  In addition, if so directed by the Lender, following and during the continuance of an
Event of Default, each Debtor shall direct the mailing of all Items of Payment from its account debtors to a post-office box designated by the Lender, or to such other additional or replacement post-office boxes pursuant to the request of the Lender
from time to time (collectively, the Lockbox). The Lender shall have unrestricted and exclusive access to the Lockbox.





(c)  Each Debtor hereby authorizes the Lender to inspect all Items of Payment, endorse all Items of Payment in the name of such Debtor, and deposit Items of
Payment in the Collateral Account. The Lender reserves the right, exercised in its sole and absolute discretion from time to time, to provide to the Collateral Account credit prior to final collection of an Item of Payment and to disallow credit for
any Item of Payment which is unsatisfactory to the Lender. In the event Items of Payment are returned to the Lender for any reason whatsoever, the Lender may, in the exercise of its discretion from time to time, forward such Items of Payment a
second time. Any returned Items of Payment shall be charged back to the Collateral Account, the Loan Account or other account, as appropriate.





(d)  The Lender will apply the whole or any part of the collected funds credited to the Collateral Account against the outstanding balance of the Revolving
Credit Facility Loans and Obligations related thereto until paid in full or credit such collected funds to the depository account of the Debtors with the Lender (or an Affiliate of the Lender), as provided in the Autoborrow Service Agreement. During
the period in which an Event of Default exists and is continuing, the Lender shall have the option to apply the whole or any part of the collected funds against the outstanding balance of the Term Loan or any Obligations related thereto.





7.  Events of Default.    If one or more of the Events of Default shall occur and be
continuing or shall exist, then and in any such event, the Lender shall have such rights and remedies in respect of the Collateral or any part thereof as are provided by the UCC and such other rights and remedies in respect thereof which it may have
at law or in equity or under this Agreement, including, without limitation, the right to (i) enter any premises where Equipment or Inventory is located and take possession of the same without demand or notice and without prior judicial
hearing or legal proceedings, which each Debtor hereby expressly waives, and/or (ii) sell all or any portion of the Collateral at any brokers board or at public or private sale, without prior notice to any Debtor except as
otherwise required by law (and if notice is required by law, after ten days




8




---

prior written notice), at such time or times and in such manner and upon such terms, whether for cash or on credit, as the Lender in its reasonable discretion
may determine. The Lender shall apply the Proceeds of any such sale and any Proceeds received by the Lender first to the payment of the reasonable costs and expenses incurred by the Lender in connection with such sale or collection, including,
without limitation, reasonable attorneys fees and legal expenses, second to the payment of the Debt in such order as the Lender may determine in accordance with the Credit Agreement until the Debt has been paid in full, and then to pay the
balance, if any, as required by law.





8.Amendments.    The provisions of this Agreement
may from time to time be waived, modified, supplemented or amended with the written consent of the Debtors and the Lender. Any waiver, permit, consent or approval of any kind or character on the part of the Lender of or to any breach or default
under this Agreement or any such waiver of any provision or condition of this Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing.





9.Defeasance.    Upon the payment in full of the Debt, this Agreement shall terminate and be of no further force or effect;provided,
however, that this Agreement shall not terminate so long as the Borrower may borrow under, or cause Letters of Credit to be issued under the Credit Agreement or any Letter of Credit remains outstanding. In connection with such termination,
the Lender agrees to execute, at the Debtors expense, such agreements and financing statements (including UCC-3s) as the Debtors reasonably request in order to evidence such termination. Until such time, however, this Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns.





10.Severability.    If any provision of this Agreement shall for any reason be held invalid or unenforceable, such invalidity or unenforceability shall not affect any other provision hereof, but this
Agreement shall be construed as if such invalid or unenforceable provision had never been contained herein.





11.Waiver.    No delay or failure on the part of the Lender in exercising any right, remedy, power or privilege hereunder shall operate as a waiver thereof or of any other right, remedy, power or
privilege of the Lender hereunder or under the Credit Agreement or any instrument or instruments now or hereafter evidencing the Debt; nor shall any single or partial exercise of any such right, remedy, power or privilege preclude any other or
further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights and remedies of the Lender under this Agreement are cumulative and not exclusive of any rights or remedies which it might otherwise have.





12.  Indemnification.    The Debtors will indemnify and save and hold the Lender harmless
from and against any and all claims, damages, losses, liabilities or judgments which may be incurred or sustained by the Lender or asserted against the Lender, directly or indirectly, in connection with the existence of or the lawful exercise of any
of the security rights with respect to the Collateral, except for matters which may result from




9




---

the gross negligence or willful misconduct of the Lender. The covenants contained in this paragraph shall survive the termination of the other provisions of
this Agreement. In the event of any action at law or suit in equity in relation to this Agreement, the Debtors, in addition to all other sums which they may be required to pay, will pay a reasonable sum for attorneys fees incurred by the
Lender in connection with such action or suit and all other expenses of collection.





13.Survival.    All representations, warranties, covenants and agreements of the Debtors contained herein or made in writing in connection herewith shall survive the execution and delivery of this
Agreement and shall continue in full force and effect from and after the date hereof until payment in full of the Debt.

ARBITRATOR(S). THE ARBITRATOR(S) SHALL HAVE THE POWER TO AWARD LEGAL FEES PURSUANT TO THE TERMS OF THIS AGREEMENT.
