(a)            Such
Lien Grantor is duly organized, validly existing and in good standing under the laws of the jurisdiction identified as its jurisdiction
of organization in its Perfection Certificate.

 

(b)            Such
Lien Grantor has good and marketable title to all its Collateral (subject to exceptions that are, in the aggregate, not material), free
and clear of any Lien other than Permitted Liens.

 

(c)            Such
Lien Grantor has not performed any acts that would prevent the Collateral Agent from enforcing any of the provisions of the Security
Documents or that would reasonably be expected to limit the Collateral Agent in any such enforcement. Such Lien Grantor has not authorized
or entered into any financing statement, security agreement, mortgage or similar or equivalent document or instrument covering all or
part of the Collateral owned by such Lien Grantor nor is it aware that any such document or instrument is on file or of record in any
jurisdiction in which such filing or recording would be effective to perfect or record a Lien on such Collateral, except financing statements,

Lien Grantor will be in the possession or under the control of any other Person having a Lien thereon, other than a Permitted Lien.

(iii) when so attached, will secure all the Secured Obligations.

 

(e)            Such
Lien Grantor has delivered a Perfection Certificate to the Collateral Agent. The information set forth therein with respect to such Lien
Grantor is correct and complete as of the date hereof. After the date hereof, the Collateral Agent or the Administrative Agent may obtain,
at the applicable Lien Grantor’s expense, a file search report from each UCC filing office listed in its Perfection Certificate,
showing the filing made at such filing office to perfect the Transaction Liens on the Collateral.

 

(f)            The
Transaction Liens constitute perfected security interests in the Collateral owned by such Lien Grantor to the extent that a security
interest therein may be perfected by filing pursuant to the UCC, prior to all Liens and rights of others therein except Permitted Liens.
With respect to such Lien Grantor and its Collateral, no registration, recordation, or filing with any governmental body, agency, or
official is required in connection with the execution or delivery of the Security Documents or is necessary for the validity or enforceability
thereof or for the perfection of the Transaction Liens pursuant to the UCC or for the enforcement of the Transaction Liens pursuant to
the UCC.

 

    13

     

    

 

(g)            Each
Lien Grantor has taken, and will continue to take, all actions necessary under the UCC to perfect its interest in any Receivables purchased
or otherwise acquired by it, as against its assignors and creditors of its assignors.

 

(h)            Each
Lien Grantor’s Collateral is insured as required by the Credit Agreement.

 

(i)            Any
Inventory produced by any Lien Grantor has or will have been produced in compliance with the applicable requirements of the Fair Labor
Standards Act, as amended.

 

Section 4.
Further Assurances; General Covenants. Each Lien Grantor covenants as follows:

 

(a)            Such
Lien Grantor will, from time to time, at its own expense, execute, deliver, authorize, file and record any statement, assignment, instrument,
document, agreement or other paper and take any other action (including (x) any filing of financing or continuation statements under
the UCC and (y) subject to Section 5(b), causing any lockbox, collection or similar account into which payments with respect
to Receivables then owned by such Lien Grantor will be received to be subjected to Blocked Account Agreements) that from time to time
may be reasonably necessary or desirable, or that the Collateral Agent may reasonably request, in order to:

 

(i)            create,
preserve, perfect, confirm or validate the Transaction Liens on the Collateral;

 

(ii)           enable
the Collateral Agent and the other Secured Parties to obtain the full benefits of the Security Documents; or

 

(iii)          enable
the Collateral Agent to exercise and enforce any of its rights, powers, and remedies with respect to any of the Collateral.

 

To the extent permitted by applicable law, each Lien Grantor authorizes
the Collateral Agent to execute and file such financing statements or continuation statements as may be necessary or appropriate to reflect
the security interests granted by this Agreement. The Collateral Agent shall provide such Lien Grantor with copies of any such financing
statements and continuation statements. Each Lien Grantor agrees that a photocopy or other reproduction of this Agreement or of a financing
statement is sufficient as a financing statement to the extent permitted by law. Each Lien Grantor constitutes the Collateral Agent its
attorney-in-fact to execute and file all filings required or so requested for the foregoing purposes, all acts of such attorney being
hereby ratified and confirmed; and such power, being coupled with an interest, shall be irrevocable until all the Transaction Liens granted
by such Lien Grantor terminate pursuant to Section 12. The Borrower will pay the reasonable and documented out-of-pocket costs of,
or incidental to, any recording or filing of any financing or continuation statements or other documents recorded or filed pursuant hereto.

 

    14

     

    

 

(b)            No
Lien Grantor will (i) change its name or organizational entity type, or (ii) change its location (determined as provided in
UCC Section 9-307) unless it shall have given the Collateral Agent prior notice thereof and delivered an Opinion of Counsel with
respect thereto in accordance with Section 4(c).

 

(c)            Within
10 days after it takes any action contemplated by Section 4(b), each Lien Grantor, at its own expense, will cause to be delivered
to the Collateral Agent an Opinion of Counsel, in form and substance reasonably satisfactory to the Collateral Agent, to the effect that
(i) all financing statements and amendments or supplements thereto, continuation statements and other documents required to be filed
or recorded in order to perfect and protect the Transaction Liens against all creditors of and purchasers from such Lien Grantor after
it takes such action (except any applicable continuation statements specified in such Opinion of Counsel that are to be filed more than
six months after the date thereof) have been filed or recorded in each office necessary for such purpose, (ii) all fees and taxes,
if any, payable in connection with such filings or recordings have been paid in full and (iii) except as otherwise agreed by the
Required Lenders, such action will not adversely affect the perfection or priority of the Transaction Lien on any Collateral to be owned
by such Lien Grantor after it takes such action or the accuracy of such Lien Grantor’s representations and warranties herein relating
to such Collateral.

 

(d)            No
Lien Grantor will sell, lease, exchange, assign or otherwise dispose of, or grant any option with respect to, any of its Collateral;
provided that each Lien Grantor may do any of the foregoing unless (i) doing so would breach a covenant in the Credit Agreement
(including, for the avoidance of doubt, the last sentence of Section 5.02(c) of the Credit Agreement) or (ii) an Event
of Default shall have occurred and be continuing and the Collateral Agent shall have notified such Lien Grantor that its right to do
so is terminated, suspended or otherwise limited. Concurrently with any sale or other disposition (except a lease) permitted by the foregoing
proviso, the Transaction Liens on the assets sold or disposed of (but not in any Proceeds arising from such sale or disposition)
will cease immediately without any action by the Collateral Agent or any other Secured Party. The Collateral Agent will, at the applicable
Lien Grantor’s expense, execute and deliver to any Lien Grantor such documents as such Lien Grantor shall reasonably request to
evidence the fact that any asset so sold or disposed of is no longer subject to a Transaction Lien.

 

    15

     

    

 

(e)            Each
Lien Grantor will use commercially reasonable efforts to cause to be collected from its Account Debtors, when due, all amounts owing
under its Receivables (including delinquent Receivables, which will be collected in accordance with lawful collection procedures) and
will apply all amounts collected thereon, forthwith upon receipt thereof, to the outstanding balances of such Receivables. Subject to
the rights of the Collateral Agent hereunder if an Event of Default shall have occurred and be continuing, each Lien Grantor may allow
in the ordinary course of business as adjustments to amounts owing under its Receivables (but without limiting the effect of the definition
of “Ineligible Receivables” contained in the Credit Agreement) (i) any extension or renewal of the time or times for
payment, or settlement for less than the total unpaid balance, that such Lien Grantor finds appropriate in accordance with sound business
judgment and (ii) refunds or credits, all in the ordinary course of business and consistent with such Lien Grantor’s historical
collection practices. The costs and expenses (including reasonable and documented attorney’s fees) of collection, whether incurred
by any Lien Grantor or the Collateral Agent, shall be paid by any Lien Grantor. If an Event of Default shall have occurred and be continuing,
each Lien Grantor will, if requested to do so by the Collateral Agent, promptly notify (and each Lien Grantor authorizes the Collateral
Agent to so notify) each Account Debtor in respect of its Receivables that such Receivables have been assigned to the Collateral Agent
hereunder, and that any payments due or to become due in respect of such Receivables are to be made directly to the Collateral Agent.

 

(f)            Each
Lien Grantor will, promptly upon request, provide to the Collateral Agent all information and evidence concerning the Collateral that
the Collateral Agent may reasonably request from time to time to enable it to enforce the provisions of the Security Documents.

 

(g)            From
time to time upon request by the Collateral Agent, each Lien Grantor will, at its own expense, cause to be delivered to the Secured Parties
an Opinion of Counsel reasonably satisfactory to the Collateral Agent as to such matters relating to the transactions contemplated hereby
as the Collateral Agent may reasonably request.

 

Section 5.
Cash Collateral Account; Blocked Accounts. (a) If and when required for purposes hereof, the Collateral Agent will establish
an account (the “Cash Collateral Account”), in the name and under the exclusive control of the Collateral Agent, into
which all amounts owned by the Lien Grantors that are to be deposited therein pursuant to the Loan Documents shall be deposited from
time to time.

 

    16

     

    

 

(b)            At
all times after the Effective Date, each Lien Grantor shall maintain a cash management system that is reasonably satisfactory to the
Collateral Agent. At all times after the Effective Date (or, in the case of any Lien Grantor that becomes a party hereto after the Effective
Date, not later than 60 days after such Lien Grantor becomes a party hereto (or such longer period as the Borrower and the Collateral
Agent may agree)), each Lien Grantor shall (i) cause each of its Lockbox Accounts and Collection Accounts to be subject to a Blocked
Account Agreement and (ii) cause all Pledged Receivables to be payable only to a Blocked Account. In addition, on each day on which
collections of Pledged Receivables are received in any Lockbox Account, each Lien Grantor shall cause such collections to be transferred
from the applicable Lockbox Account to a Collection Account. If any Lien Grantor receives collections in respect of Pledged Receivables
other than in a Blocked Account, such Lien Grantor shall immediately (or, in the case of any Lien Grantor that becomes a party hereto
after the Effective Date, on and after the date that is 60 days after such Lien Grantor becomes a party hereto (or such longer period
as the Borrower and the Collateral Agent may agree)) cause such collections to be deposited into a Blocked Account; provided that
U.S. Steel Oilwell Services, LLC shall not be subject to the requirements of this Section 5(b) until such time as Receivables
that would constitute Eligible Receivables of U.S. Steel Oilwell Services, LLC exceed $20,000,000 and (i) Aggregate Facility Availability
is less than the greater of (x) the amount that is 20% of the aggregate amount of the Commitments and (y) $400,000,000 or (ii) a
Default under paragraph (a), (b), (e)(i) or (f) (solely as a result of failure to comply with Section 5 of any Security
Agreement) of Article 7 of the Credit Agreement occurs (it being understood and agreed that until the requirements of this Section 5(b) of
the Security Agreement have been satisfied no Receivables of Oilwell Services shall constitute Eligible Receivables).

 

(c)            Upon
the occurrence and during the continuation of an Event of Default or if a Sweep Period shall have occurred and be continuing, the Collateral
Agent may at any time thereafter give notice to any applicable depositary bank that the Collateral Agent is exercising its rights under
the applicable Blocked Account Agreements to do any or all of the following: (i) to have the exclusive control of the Blocked Accounts
and to exercise exclusive dominion and control over the funds and other assets deposited therein, (ii) to have the proceeds that
are sent to the Blocked Accounts redirected pursuant to the Collateral Agent’s instructions, (iii) cause all amounts on deposit
in any Blocked Account to be transferred to the Cash Collateral Account, (iv) subject to clause (d), retain all cash and investments
then held in any Blocked Account or the Cash Collateral Account and liquidate any or all investments held therein, and (v) to take
any or all other actions permitted under the applicable Blocked Account Agreement. Upon the occurrence and during the continuation of
an Event of Default, the Collateral Agent may also withdraw any amounts contained in a Blocked Account or the Cash Collateral Account
and apply such amounts as provided in Section 7. Each Lien Grantor hereby agrees that if the Collateral Agent at any time takes
any action set forth in the preceding sentence, the Collateral Agent shall have exclusive control of the proceeds (including collections)
of all Pledged Receivables and each Lien Grantor further agrees to take any other action that the Collateral Agent may reasonably request
to transfer such control.

 

    17

     

    

 

(d)            During
any Sweep Period (i) all amounts held in the Cash Collateral Account (other than amounts deposited therein pursuant to Section 2.11(b),
Section 2.16(j) or Section 5.10(b) of the Credit Agreement as cash collateral for the LC Exposure) shall be applied
on a daily basis to first, the outstanding principal balance of the Base Rate Tranche A Loans until repaid in full, or, if applicable,
as provided in Section 7, (ii) second, following repayment in full of all outstanding Base Rate Tranche A Loans pursuant
to clause (i), any remaining amounts held in the Cash Collateral Account shall continue to be held in the Cash Collateral Account and
(other than amounts deposited therein pursuant to Section 2.11(b), Section 2.16(j) or Section 5.10(b) of the
Credit Agreement as cash collateral for the LC Exposure) shall be applied to the outstanding principal balance of maturing Term Benchmark
Tranche A Loans upon expiration of the Interest Periods applicable thereto, (iii) third, following repayment in full of all
outstanding Term Benchmark Tranche A Loans pursuant to clause (ii), any remaining amounts held in the Cash Collateral Account shall continue
to be held in the Cash Collateral Account and (other than amounts deposited therein pursuant to Section 2.11(b), Section 2.16(j) or
Section 5.10(b) of the Credit Agreement as cash collateral for the LC Exposure) shall be applied to the outstanding principal
balance of the Base Rate Tranche B Loans until repaid in full and (iv) fourth, following repayment in full of all outstanding
Base Rate Tranche B Loans pursuant to clause (iii), any remaining amounts held in the Cash Collateral Account shall continue to be held
in the Cash Collateral Account and (other than amounts deposited therein pursuant to Section 2.11(b), Section 2.16(j) or
Section 5.10(b) of the Credit Agreement as cash collateral for the LC Exposure) shall be applied to the outstanding principal
balance of maturing Term Benchmark Tranche B Loans upon expiration of the Interest Periods applicable thereto.

 

(e)            Unless
(x) a Sweep Period shall have occurred and be continuing, (y) an Event of Default shall have occurred and be continuing and
the Required Lenders shall have instructed the Collateral Agent to stop withdrawing amounts from the Cash Collateral Account pursuant
to this subsection or (z) the maturity of the Loans shall have been accelerated pursuant to Article 7 of the Credit Agreement
or pursuant to the proviso to the definition of “Termination Date” contained in the Credit Agreement (or otherwise), the
Collateral Agent shall withdraw amounts from the Cash Collateral Account (other than amounts required to be deposited in the Cash Collateral
Account pursuant to Section 2.11(b), 2.16(j) or Section 5.10(b) of the Credit Agreement) and remit such amounts to,
or as directed by, each applicable Lien Grantor from time to time.

 

(f)            Funds
held in any Blocked Account or the Cash Collateral Account may, until withdrawn or otherwise applied pursuant hereto, be invested and
reinvested in such Liquid Investments as each applicable Lien Grantor shall request from time to time; provided that, if an Event of
Default shall have occurred and be continuing, the Collateral Agent may select such Liquid Investments.

 

    18

     

    

 

(g)            If
immediately available cash on deposit in any Blocked Account or the Cash Collateral Account is not sufficient to make any distribution
or withdrawal to be made pursuant hereto, the Collateral Agent will cause to be liquidated, as promptly as practicable, such investments
held in or credited to such account as shall be required to obtain sufficient cash to make such distribution or withdrawal and, notwithstanding
any other provision hereof, such distribution or withdrawal shall not be made until such liquidation has taken place.

 

Section 6.
Remedies upon Event of Default. (a) If an Event of Default shall have occurred and be continuing, the Collateral Agent may exercise
(or cause its sub-agents to exercise) any or all of the remedies available to it (or to such sub-agents) under the Security Documents.

 

(b)            Without
limiting the generality of the foregoing, if an Event of Default shall have occurred and be continuing, the Collateral Agent may exercise
on behalf of the Secured Parties all the rights of a secured party under the UCC (whether or not in effect in the jurisdiction where
such rights are exercised) with respect to any Collateral and, in addition, the Collateral Agent may, without being required to give
any notice, except as herein provided or as may be required by mandatory provisions of law, withdraw all cash held in the Cash Collateral
Account or any Blocked Account and apply such cash as provided in Section 7 and, if there shall be no such cash or if such cash
shall be insufficient to pay all the Secured Obligations in full, sell, lease, license or otherwise dispose of the Collateral or any
part thereof. Notice of any such sale or other disposition shall be given to the applicable Lien Grantor as required by Section 9.

 

(c)            Without
limiting the generality of the foregoing, during any Sweep Period, the Collateral Agent may (i) exercise all of the remedies described
in Section 5(d) and (ii) cause all amounts constituting Collateral that are held in any lockbox, collection or other account
of any Lien Grantor then subject to an effective Blocked Account Agreement to be transferred on a daily basis to the Cash Collateral
Account.

 

Section 7.
Application of Proceeds. (a) If an Event of Default shall have occurred and be continuing, the Collateral Agent may apply
(i) any cash held in the Cash Collateral Account and (ii) the proceeds of any sale or other disposition of all or any part
of the Collateral, in the following order of priorities:

 

first, to pay the expenses of such sale
or other disposition, including reasonable compensation to agents of and counsel for the Collateral Agent, and all expenses, liabilities
and advances incurred or made by the Collateral Agent in connection with the Security Documents, and any other amounts then due and payable
to the Collateral Agent pursuant to Section 8 or to any Agent pursuant to the Credit Agreement;

 

    19

     

    

 

second, ratably to (i) pay the Secured
Obligations consisting of unpaid principal of the Tranche A Loans and First Secured Derivative Obligations ratably (or to provide for
the payment thereof pursuant to Section 7(b)) and (ii) cash collateralize LC Exposures, until payment in full of the principal
of all such Secured Obligations described in this clause second shall have been made (or so provided for) and all LC Exposures
have been Cash Collateralized;

 

third, to pay ratably the Secured Obligations
consisting of all interest (including Post-Petition Interest) on the Tranche A Loans and all commitment and other fees payable under
the Related Documents with respect to the Tranche A Loans and related commitments, until payment in full of all such interest and fees
shall have been made;

 

fourth, to pay the Secured Obligations
consisting of unpaid principal of the Tranche B Loans ratably (or to provide for the payment thereof pursuant to Section 7(b)),
until payment in full of the principal of all such Secured Obligations described in this clause fourth shall have been made (or
so provided for);

 

fifth, to pay ratably the Secured Obligations
consisting of all interest (including Post-Petition Interest) on the Tranche B Loans and all commitment and other fees payable under
the Related Documents with respect to the Tranche B Loans and related commitments, until payment in full of all such interest and fees
shall have been made;

 

sixth, to pay all other Secured Obligations
(other than the Secured Bi-Lateral Letter of Credit Obligations, the Secured Cash Management Obligations, the Secured Vendor Financing
Obligations and the Second Secured Derivative Obligations) ratably (or to provide for the payment thereof pursuant to Section 7(b)),
until payment in full of all such other Secured Obligations (other than the Secured Bi-Lateral Letter of Credit Obligations, the Secured
Cash Management Obligations, the Secured Vendor Financing Obligations and the Second Secured Derivative Obligations) shall have been
made (or so provided for);

 

seventh, to pay ratably the unpaid principal
of the Secured Bi-Lateral Letter of Credit Obligations, the Secured Cash Management Obligations, and the Secured Vendor Financing Obligations
(or to provide payment therefor pursuant to Section 7(b)), until payment in full of the principal of all Secured Bi-Lateral Letter
of Credit Obligations, Secured Cash Management Obligations and Secured Vendor Financing Obligations shall have been made (or so provided
for);

 

eighth, to pay ratably all interest (including
Post-Petition Interest) on the Secured Bi-Lateral Letter of Credit Obligations, the Secured Cash Management Obligations, the Secured
Vendor Financing Obligations and the First Secured Derivative Obligations, until payment in full of all such interest has been made;

 

    20

     

    

 

ninth, to pay ratably all the unpaid principal
of the Second Secured Derivative Obligations;

 

tenth, to pay ratably all interest on the
Second Secured Derivative Obligations; and

 

finally, to pay to the Lien Grantors, or
as a court of competent jurisdiction may direct, any surplus then remaining from the proceeds of the Collateral owned by it.

 

The Collateral Agent may make such distributions
hereunder in cash or in kind or, on a ratable basis, in any combination thereof.

 

Notwithstanding anything to the contrary herein,
the parties hereto agree that the unpaid principal (i.e., the Mark-to-Market Value) of the First Secured Derivative Obligations shall
be paid, ratably with the unpaid principal of other Secured Obligations with respect to the Tranche A Loans, pursuant to clause second;
provided that if on the date of any application of cash or proceeds in accordance with this Section 7(a), the aggregate Mark-to-Market
Value of First Secured Derivative Obligations exceeds an amount equal to (x) $200,000,000 minus (y) the aggregate Mark-to-Market
Value of First Secured Derivative Obligations previously paid pursuant to this Section 7(a) and Section 7(a) of the
Borrower Security Agreement (such amount, the “Available Derivative Amount” at such date), then: (x) the Secured
Obligations payable pursuant to clause second shall be the Mark-to-Market Value of First Secured Derivative Obligations in an aggregate
amount equal to the Available Derivative Amount at such date (which Available Derivative Amount shall represent and be comprised of a
ratable portion (the “Permitted Ratable Portion”) of the Mark-to-Market Value of each First Secured Derivative Obligation),
and (y) the portion of the Mark-to-Market Value of each First Secured Derivative Obligation that is in excess of the Permitted Ratable
Portion referred to in clause (x) (and is therefore not paid ratably with the unpaid principal of Secured Obligations with respect
to the Tranche A Loans pursuant to clause second) shall, for all purposes of this Section 7(a), be treated as and deemed to be unpaid
principal of a Second Secured Derivative Obligation, and shall be paid, ratably with the unpaid principal of all other Second Secured
Derivative Obligations, pursuant to clause ninth.

 

    21

     

    

 

(b)            If
at any time any portion of any monies collected or received by the Collateral Agent would, but for the provisions of this Section 7(b),
be payable pursuant to Section 7(a) in respect of an Unliquidated Secured Obligation, the Collateral Agent shall not apply
any monies to pay such Unliquidated Secured Obligation but instead shall request the holder thereof, at least 10 days before each proposed
distribution hereunder, to notify the Collateral Agent as to the maximum amount of such Unliquidated Secured Obligation if then ascertainable
(e.g., in the case of a letter of credit, the maximum amount available for subsequent drawings thereunder). If the holder of such
Unliquidated Secured Obligation does not notify the Collateral Agent of the maximum ascertainable amount thereof at least two Domestic
Business Days before such distribution, such Unliquidated Secured Obligation will not be entitled to share in such distribution. If such
holder does so notify the Collateral Agent as to the maximum ascertainable amount thereof, the Collateral Agent will allocate to such
holder a portion of the monies to be distributed in such distribution, calculated as if such Unliquidated Secured Obligation were outstanding
in such maximum ascertainable amount. However, the Collateral Agent will not apply such portion of such monies to pay such Unliquidated
Secured Obligation, but instead will hold such monies or invest such monies in Liquid Investments. All such monies and Liquid Investments
and all proceeds thereof will constitute Collateral hereunder, but will be subject to distribution in accordance with this Section 7(b) rather
than Section 7(a). The Collateral Agent will hold all such monies and Liquid Investments and the net proceeds thereof in trust until
all or part of such Unliquidated Secured Obligation becomes a Liquidated Secured Obligation, whereupon the Collateral Agent at the request
of the relevant Secured Party will apply the amount so held in trust to pay such Liquidated Secured Obligation; provided that,
if the other Secured Obligations theretofore paid pursuant to the same clause of Section 7(a) were not paid in full, the Collateral
Agent will apply the amount so held in trust to pay the same percentage of such Liquidated Secured Obligation as the percentage of such
other Secured Obligations theretofore paid pursuant to the same clause of Section 7(a). If (i) the holder of such Unliquidated
Secured Obligation shall advise the Collateral Agent that no portion thereof remains in the category of an Unliquidated Secured Obligation
and (ii) the Collateral Agent still holds any amount held in trust pursuant to this Section 7(b)in respect of such Unliquidated
Secured Obligation (after paying all amounts payable pursuant to the preceding sentence with respect to any portions thereof that became
Liquidated Secured Obligations), such remaining amount will be applied by the Collateral Agent in the order of priorities set forth in
Section 7(a).

 

(c)            In
making the payments and allocations required by this Section, the Collateral Agent may rely upon information supplied to it pursuant
to Section 11(g). All distributions made by the Collateral Agent pursuant to this Section shall be final (except in the case
of manifest error) and the Collateral Agent shall have no duty to inquire as to the application by any Secured Party of any amount distributed
to it.

 

Section 8.
Fees and Expenses; Indemnification. (a) Each Lien Grantor will forthwith upon demand pay to the Collateral Agent:

 

(i)            the
amount of any taxes that the Collateral Agent may have been required to pay by reason of the Transaction Liens or to free any Collateral
from any other Lien thereon;

 

    22

     

    

 

(ii)            the
amount of any and all reasonable and documented out-of-pocket expenses, including transfer taxes and reasonable and documented fees and
expenses of counsel and other experts, that the Collateral Agent may incur in connection with (x) the administration or enforcement
of the Security Documents, including such expenses as are incurred to preserve the value of the Collateral or the validity, perfection,
rank or value of any Transaction Lien, (y) the collection, sale or other disposition of any Collateral or (z) the exercise
by the Collateral Agent of any of its rights or powers under the Security Documents;

 

(iii)           the
amount of any fees that such Lien Grantor shall have agreed in writing to pay to the Collateral Agent and that shall have become due
and payable in accordance with such written agreement; and

 

(iv)           the
amount required to indemnify the Collateral Agent for, or hold it harmless and defend it against, any loss, liability or expense (including
the reasonable and documented fees and expenses of its counsel and any experts or sub-agents appointed by it hereunder) incurred or suffered
by the Collateral Agent in connection with the Security Documents, except to the extent that such loss, liability or expense arises from
the Collateral Agent’s gross negligence or willful misconduct or a breach of any duty that the Collateral Agent has under this
Agreement (after giving effect to Sections 10 and 11).

 

Any such amount not paid to the Collateral Agent on demand will bear
interest for each day thereafter until paid at a rate per annum equal to the sum of 2.00% plus the Base Rate for such day plus the Applicable
Rate that would, in the absence of an Event of Default, be applicable to the Base Rate Loans for such day.

 

(b)            If
any transfer tax, documentary stamp tax or other tax is payable in connection with any transfer or other transaction provided for in
the Security Documents, the applicable Lien Grantor will pay such tax and provide any required tax stamps to the Collateral Agent or
as otherwise required by law.

 

Section 9.
Authority to Administer Collateral. Each Lien Grantor irrevocably appoints the Collateral Agent its true and lawful attorney, with
full power of substitution, in the name of such Lien Grantor, any Secured Party or otherwise, for the sole use and benefit of the Secured
Parties, but at such Lien Grantor’s expense, to the extent permitted by law to exercise, at any time and from time to time while
an Event of Default shall have occurred and be continuing, all or any of the following powers with respect to all or any of the Collateral
(to the extent necessary to pay the Secured Obligations in full):

 

(a)            to
demand, sue for, collect, receive and give acquittance for any and all monies due or to become due upon or by virtue thereof,

 

    23

     

    

 

 

(b)            to
settle, compromise, compound, prosecute or defend any action or proceeding with respect thereto,

 

(c)            to
sell, lease, license or otherwise dispose of the same or the proceeds or avails thereof, as fully and effectually as if the Collateral
Agent were the absolute owner thereof, and

 

(d)            to
extend the time of payment of any or all thereof and to make any allowance or other adjustment with reference thereto;

 

provided that, except in the case of Collateral that is perishable
or threatens to decline speedily in value or is of a type customarily sold on a recognized market, the Collateral Agent will give the
applicable Lien Grantor at least ten days’ prior written notice of the time and place of any public sale thereof or the time after
which any private sale or other intended disposition thereof will be made. Any such notice shall (i) contain the information specified
in UCC Section 9-613, (ii) be Authenticated and (iii) be sent to the parties required to be notified pursuant to UCC Section 9-611(c);
provided that, if the Collateral Agent fails to comply with this sentence in any respect, its liability for such failure shall
be limited to the liability (if any) imposed on it as a matter of law under the UCC.

 

Section 10.
Limitation on Duty in Respect of Collateral.  Beyond the exercise of reasonable care in the custody and preservation thereof, the
Collateral Agent will have no duty as to any Collateral in its possession or control or in the possession or control of any sub-agent
or bailee or any income therefrom or as to the preservation of rights against prior parties or any other rights pertaining thereto. The
Collateral Agent will be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession
or control if such Collateral is accorded treatment substantially equal to that which it accords its own property, and will not be liable
or responsible for any loss or damage to any Collateral, or for any diminution in the value thereof, by reason of any act or omission
of any sub-agent or bailee selected by the Collateral Agent in good faith or by reason of any act or omission by the Collateral Agent
pursuant to instructions from the Administrative Agent, except to the extent that such liability arises from the Collateral Agent’s
gross negligence or willful misconduct.

 

Section 11.
General Provisions Concerning the Collateral Agent. (a) Authority. The Collateral Agent is authorized to take such actions
and to exercise such powers as are delegated to the Collateral Agent by the terms of the Security Documents, together with such actions
and powers as are reasonably incidental thereto.

 

(b)            Coordination
with Secured Parties. To the extent requested to do so by any Secured Party, the Collateral Agent will promptly notify such Secured
Party of each notice or other communication received by the Collateral Agent hereunder and/or deliver a copy thereof to such Secured
Party. As to any matters not expressly provided for herein (including (i) the timing and methods of realization upon the Collateral
and (ii) the exercise of any power that the Collateral Agent may, but is not expressly required to, exercise under any Security
Document), the Collateral Agent shall act or refrain from acting in accordance with written instructions from the Required Lenders or,
in the absence of such instructions, in accordance with its discretion (subject to the following provisions of this Section).

 

    24

     

    

 

(c)            Rights
and Powers as a Secured Party. The Person serving as the Collateral Agent shall, in its capacity as a Secured Party, have the same
rights and powers as any other Secured Party and may exercise the same as though it were not the Collateral Agent. Such Person and its
Affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower, any of its Subsidiaries
(including any Lien Grantor) or their respective Affiliates as if it were not the Collateral Agent hereunder.

 

(d)            Limited
Duties and Responsibilities. The Collateral Agent shall not have any duties or obligations under the Security Documents except those
expressly set forth therein. Without limiting the generality of the foregoing, (a) the Collateral Agent shall not be subject to
any fiduciary or other implied duties, regardless of whether an Event of Default has occurred and is continuing, (b) the Collateral
Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and
powers expressly contemplated by the Security Documents that the Collateral Agent is required in writing to exercise by the Required
Lenders, and (c) except as expressly set forth in the Security Documents, the Collateral Agent shall not have any duty to disclose,

Collateral Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders

for the existence, genuineness, or value of any Collateral or for the validity, perfection, priority, or enforceability of any Transaction
Lien, whether impaired by operation of law or by reason of any action or omission to act on its part under the Security Documents. The

Collateral Agent by the Borrower or a Secured Party, and the Collateral Agent shall not be responsible for or have any duty to ascertain
or inquire into (i) any statement, warranty or representation made in or in connection with any Security Document, (ii) the
contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set forth in any Security Document, (iv) the validity,

(e)            Authority
to Rely on Certain Writings, Statements, and Advice. The Collateral Agent shall be entitled to rely on, and shall not incur any liability
for relying on, any notice, request, certificate, consent, statement, instrument, document, or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. The Collateral Agent also may rely on any statement made to it orally or by telephone
and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Collateral Agent may consult
with legal counsel (who may be counsel for the Borrower or any of its Subsidiaries (including any Lien Grantor)), independent accountants
and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any
such counsel, accountant or expert. The Collateral Agent may rely conclusively on advice from the Administrative Agent as to whether
at any time (i) an Event of Default under the Credit Agreement has occurred and is continuing, (ii) the maturity of the Loans
has been accelerated or (iii) any proposed action is permitted or required by the Credit Agreement.

 

(f)            Sub-Agents
and Related Parties. The Collateral Agent may perform any of its duties and exercise any of its rights and powers through one or
more sub-agents appointed by it. The Collateral Agent and any such sub-agent may perform any of its duties and exercise any of its rights
and powers through its Related Parties. The exculpatory provisions of Section 10 and this Section shall apply to any such sub-agent
and to the Related Parties of the Collateral Agent and any such sub-agent.

 

(g)            Information
as to Secured Obligations and Actions by Secured Parties. For all purposes of the Security Documents, including determining the amounts
of the Secured Obligations and whether a Secured Obligation is an Unliquidated Secured Obligation or not, or whether any action has been
taken under any Secured Agreement, the Collateral Agent will be entitled to rely on information from (i) the Administrative Agent
for information as to the Lenders, the Administrative Agent or the Collateral Agent, their Secured Obligations and actions taken by them,
(ii) any Secured Party for information as to its Secured Obligations and actions taken by it, to the extent that the Collateral
Agent has not obtained such information from the foregoing sources, and (iii) the Borrower or any Lien Grantor, to the extent that
the Collateral Agent has not obtained information from the foregoing sources.

 

(h)            Within
two Business Days after it receives or sends any notice referred to in this subsection, the Collateral Agent shall send to the Administrative
Agent and each Secured Party requesting notice thereof, copies of any notice given by the Collateral Agent to any Lien Grantor, or received
by it from any Lien Grantor; provided that such Secured Party has, at least five Business Days prior thereto, delivered to the
Collateral Agent a written notice (i) stating that it holds one or more Secured Obligations and wishes to receive copies of such
notices and (ii) setting forth its address, facsimile number and e-mail address to which copies of such notices should be sent.

 

    26

     

    

 

(i)            The
Collateral Agent may refuse to act on any notice, consent, direction or instruction from the Administrative Agent or any Secured Parties
or any agent, trustee or similar representative thereof that, in the Collateral Agent’s opinion, (i) is contrary to law or
the provisions of any Security Document, (ii) may expose the Collateral Agent to liability (unless the Collateral Agent shall have
been indemnified, to its reasonable satisfaction, for such liability by the Secured Parties that gave, or instructed the Agent to give,
such notice, consent, direction or instruction) or (iii) is unduly prejudicial to Secured Parties not joining in such notice, consent,
direction or instruction.

 

(j)            Resignation;
Successor Collateral Agent. Subject to the appointment and acceptance of a successor Collateral Agent as provided in this subsection,
the Collateral Agent may resign at any time by notifying the Secured Parties and the Borrower. Upon any such resignation, the Required
Lenders shall have the right, in consultation with the Borrower, to appoint a successor Collateral Agent. If no successor shall have
been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Collateral Agent
gives notice of its resignation, then the retiring Collateral Agent may, on behalf of the Secured Parties, appoint a successor Collateral
Agent which shall be a bank with an office in the United States, or an Affiliate of any such bank. Upon acceptance of its appointment
as Collateral Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Collateral Agent hereunder, and the retiring Collateral Agent shall be discharged from its duties and obligations
hereunder. The fees payable by the Lien Grantors to a successor Collateral Agent shall be the same as those payable to its predecessor
unless otherwise agreed by the Lien Grantors and such successor. After the Collateral Agent’s resignation hereunder, the provisions
of this Section and Section 10 shall continue in effect for the benefit of such retiring Collateral Agent, its sub-agents and
their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Collateral
Agent was acting as Collateral Agent.

    27

     

    

 

(b)            The
Transaction Liens (x) with respect to any Pledged Receivables shall terminate when such Receivables have become Transferred Receivables
and (y) with respect to any other Collateral shall terminate upon the sale of such Collateral to a Person other than a Credit Party
in a transaction not prohibited by the Credit Agreement. In each case, such termination shall not require the consent of any Secured
Party, and the Collateral Agent and any third party shall be fully protected in relying on a certificate of the Borrower as to whether
any Pledged Receivables qualify as Transferred Receivables (including whether the transfer thereof is permitted under the Credit Agreement
and this Agreement).

 

(c)            If
the Borrower delivers a certificate pursuant to Section 12(b) stating that any Pledged Receivables qualify as Transferred Receivables,
the Collateral Agent and any third party shall be fully protected in relying on such certificate as conclusive proof that the Transferred
Receivables are not Collateral.

 

(d)            At
any time before the Transaction Liens terminate, the Collateral Agent may, at the written request of the Borrower, (i) release any
Collateral (but not all or substantially all of the Collateral) with the prior written consent of the Required Lenders or (ii) release
all or substantially all of the Collateral with the prior written consent of all the Lenders.

 

(e)            Upon
any termination of a Transaction Lien or release of Collateral, the Collateral Agent will, at the expense of the applicable Lien Grantor,
execute and deliver to such Lien Grantor such documents as such Lien Grantor shall reasonably request to evidence the termination of
such Transaction Lien or the release of such Collateral, as the case may be. Each Secured Party consents to the Collateral Agent’s
delivery of, and hereby directs the Collateral Agent to deliver, such release documents.

Lien Grantor has good and marketable title to all its Collateral (subject to exceptions that are, in the aggregate, not material), free
and clear of any Lien other than Permitted Liens.

Lien Grantor has not performed any acts that would prevent the Collateral Agent from enforcing any of the provisions of the Security Documents

(f)            The
Transaction Liens constitute perfected security interests in the Collateral owned by the Lien Grantor to the extent that a security interest
therein may be perfected by filing pursuant to the PPSA, prior to all Liens and rights of others therein except Permitted Liens. With
respect to the Lien Grantor and its Collateral, no registration, recordation, or filing with any governmental body, agency, or official
is required in connection with the execution or delivery of the Security Documents or is necessary for the validity or enforceability
thereof or for the perfection of the Transaction Liens pursuant to the PPSA or for the enforcement of the Transaction Liens pursuant to
the PPSA.

 

(g)            The
Lien Grantor has taken, and will continue to take, all actions necessary under the PPSA to perfect its interest in any Receivables purchased
or otherwise acquired by it, as against its assignors and creditors of its assignors.

 

(h)            The
Lien Grantor’s Collateral is insured as required by the Credit Agreement.

 

(i)             Any
Inventory produced by the Lien Grantor has or will have been produced in compliance with the applicable requirements of the Fair Labor
Standards Act, as amended, or any other applicable Canadian federal, provincial or territorial law dealing with such matters.

 

Section 4.
Further Assurances; General Covenants. The Lien Grantor covenants as follows:

 

(a)            The
Lien Grantor will, from time to time, at its own expense, execute, deliver, authorize, file and record any statement, assignment, instrument,
document, agreement or other paper and take any other action (including (x) any filing of financing or financing change statements
under the PPSA and (y) subject to Section 5(b) of the Borrower US Security Agreement, causing any lockbox, collection or
similar account into which payments with respect to Receivables then owned by the Lien Grantor will be received to be subjected to Blocked
Account Agreements) that from time to time may be reasonably necessary or desirable, or that the Collateral Agent may reasonably request,
in order to:

 

(i)            create,
preserve, perfect, confirm or validate the Transaction Liens on the Collateral;

 

(ii)           enable
the Collateral Agent and the other Secured Parties to obtain the full benefits of the Security Documents; or

 

(iii)          enable
the Collateral Agent to exercise and enforce any of its rights, powers and remedies with respect to any of the Collateral.

 

    	 	12	 

     

    

 

To the extent permitted by applicable law, the Lien Grantor authorizes
the Collateral Agent to execute and file such financing statements or financing change statements as may be necessary or appropriate to
reflect the security interests granted by this Agreement. The Collateral Agent shall provide the Lien Grantor with copies of any such
financing statements and financing change statements. The Lien Grantor agrees that a photocopy or other reproduction of this Agreement
or of a financing statement is sufficient as a financing statement to the extent permitted by law. The Lien Grantor constitutes the Collateral
Agent its attorney-in-fact to execute and file all filings required or so requested for the foregoing purposes, all acts of such attorney
being hereby ratified and confirmed; and such power, being coupled with an interest, shall be irrevocable until all the Transaction Liens
granted by the Lien Grantor terminate pursuant to Section 12. The Borrower will pay the reasonable and documented out-of-pocket costs
of, or incidental to, any recording or filing of any financing or financing change statements or other documents recorded or filed pursuant
hereto.

 

(b)            The
Lien Grantor will not (i) change its name or structure as a corporation, (ii) change its jurisdiction of organization, incorporation
or amalgamation or the location of its principal place of business or chief executive office (or, if the Lien Grantor is domiciled in
Quebec, domicile for the purposes of the Quebec Civil Code) from the jurisdictions listed in its Perfection Certificate or (iii) change,
or add to, the locations of Collateral listed in its Perfection Certificate, other than Inventory that is in transit in the ordinary
course of the Lien Grantor’s business, unless, in each case, it shall have given the Collateral Agent 30 days prior written notice
thereof and delivered an Opinion of Counsel with respect thereto in accordance with Section 4(c).

 

(c)            Within
10 days after it takes any action contemplated by Section 4(b), the Lien Grantor, at its own expense, will cause to be delivered
to the Collateral Agent an Opinion of Counsel, in form and substance reasonably satisfactory to the Collateral Agent, to the effect that
(i) all financing statements, financing change statements and amendments or supplements thereto, and other documents required to
be filed or recorded in order to perfect and protect the Transaction Liens against all creditors of and purchasers from the Lien Grantor
after it takes such action have been filed or recorded in each office necessary for such purpose, (ii) all fees and taxes, if any,
payable in connection with such filings or recordings have been paid in full and (iii) except as otherwise agreed by the Required
Lenders, such action will not adversely affect the perfection or priority of the Transaction Lien on any Collateral to be owned by the
Lien Grantor after it takes such action or the accuracy of the Lien Grantor’s representations and warranties herein relating to
such Collateral.

 

    	 	13	 

     

    

 

(d)            The
Lien Grantor will not sell, lease, exchange, assign or otherwise dispose of, or grant any option with respect to, any of its Collateral;
provided that the Lien Grantor may do any of the foregoing unless (i) doing so would breach a covenant in the Credit Agreement
(including, for the avoidance of doubt, the last sentence of Section 5.02(c) of the Credit Agreement) or (ii) an Event
of Default shall have occurred and be continuing and the Collateral Agent shall have notified the Lien Grantor that its right to do so
is terminated, suspended or otherwise limited. Concurrently with any sale or other disposition (except a lease) permitted by the foregoing
proviso, the Transaction Liens on the assets sold or disposed of (but not in any Proceeds arising from such sale or disposition)
will cease immediately without any action by the Collateral Agent or any other Secured Party. The Collateral Agent will, at the Borrower’s
expense, execute and deliver to the Lien Grantor such documents as the Lien Grantor shall reasonably request to evidence the fact that
any asset so sold or disposed of is no longer subject to a Transaction Lien.

 

(e)            The
Lien Grantor will use commercially reasonable efforts to cause to be collected from its account debtors, when due, all amounts owing under
its Receivables (including delinquent Receivables, which will be collected in accordance with lawful collection procedures) and will apply
all amounts collected thereon, forthwith upon receipt thereof, to the outstanding balances of such Receivables. Subject to the rights
of the Collateral Agent hereunder if an Event of Default shall have occurred and be continuing, the Lien Grantor may allow in the ordinary
course of business as adjustments to amounts owing under its Receivables (but without limiting the effect of the definition of “Ineligible
Receivables” contained in the Credit Agreement) (i) any extension or renewal of the time or times for payment, or settlement
for less than the total unpaid balance, that the Lien Grantor finds appropriate in accordance with sound business judgment and (ii) refunds
or credits, all in the ordinary course of business and consistent with the Lien Grantor’s historical collection practices. The costs
and expenses (including reasonable and documented attorney’s fees) of collection, whether incurred by the Lien Grantor or the Collateral
Agent, shall be paid by the Lien Grantor. If an Event of Default shall have occurred and be continuing, the Lien Grantor will, if requested
to do so by the Collateral Agent, promptly notify (and the Lien Grantor authorizes the Collateral Agent to so notify) each account debtor
in respect of its Receivables that such Receivables have been assigned to the Collateral Agent hereunder, and that any payments due or
to become due in respect of such Receivables are to be made directly to the Collateral Agent.

 

(f)            The
Lien Grantor will, promptly upon request, provide to the Collateral Agent all information and evidence concerning the Collateral that
the Collateral Agent may reasonably request from time to time to enable it to enforce the provisions of the Security Documents.

 

(g)            From
time to time upon request by the Collateral Agent, the Lien Grantor will, at its own expense, cause to be delivered to the Secured Parties
an Opinion of Counsel reasonably satisfactory to the Collateral Agent as to such matters relating to the transactions contemplated hereby
as the Collateral Agent may reasonably request.

Section 6.
Remedies upon Event of Default.

 

(a)            If
an Event of Default shall have occurred and be continuing, the Collateral Agent may exercise (or cause its sub-agents to exercise) any
or all of the remedies available to it (or to such sub-agents) under the Security Documents.

 

(b)            Without
limiting the generality of the foregoing, if an Event of Default shall have occurred and be continuing, the Collateral Agent may exercise
on behalf of the Secured Parties all the rights of a secured party under the PPSA (whether or not in effect in the jurisdiction where
such rights are exercised) with respect to any Collateral and, in addition, the Collateral Agent may, without being required to give any
notice, except as herein provided or as may be required by mandatory provisions of law, withdraw all cash held in the Cash Collateral
Account or any Blocked Account and apply such cash as provided in Section 7 and, if there shall be no such cash or if such cash shall
be insufficient to pay all the Secured Obligations in full, sell, lease, license or otherwise dispose of the Collateral or any part thereof.
Notice of any such sale or other disposition shall be given to the Lien Grantor as required by Section 9.

 

(c)            Without
limiting the generality of the foregoing, during any Sweep Period, the Collateral Agent may (i) exercise all of the remedies described
in Section 5(d) of the Borrower US Security Agreement and (ii) cause all amounts constituting Collateral that are held
in any lockbox, collection or other account of the Lien Grantor then subject to an effective Blocked Account Agreement to be transferred
on a daily basis to the Cash Collateral Account.

 

(d)            Upon
the occurrence and during the continuance of an Event of Default, the Collateral Agent may appoint or reappoint by instrument in writing,
any Person or Persons, whether an officer or officers or an employee or employees of such Lien Grantor or not, to be an interim receiver,
receiver or receivers (hereinafter called a “Receiver”, which term when used herein shall include a receiver
and manager) of the Collateral located in Canada (hereinafter called the “Canadian Collateral”) of such Lien
Grantor (including any interest, income or profits therefrom) and may remove any Receiver so appointed and appoint another in its stead.
Subject to the provisions of the instrument appointing a Receiver, any such Receiver shall (i) have such powers as have been granted
to the Collateral Agent under this Section 6, and (ii) shall be entitled to exercise such powers at any time that such powers
would otherwise be exercisable by the Collateral Agent under this Section 6, which powers shall include the power to take possession
of the Canadian Collateral, to preserve the Canadian Collateral or its value, and to sell, lease, license or otherwise dispose of or concur
in selling, leasing, licensing or otherwise disposing of the Canadian Collateral. To facilitate the foregoing powers, any such Receiver
may, to the exclusion of all others, including such Lien Grantor, enter upon and occupy all premises in Canada owned or occupied by such
Lien Grantor wherein the Canadian Collateral may be situated, maintain the Canadian Collateral upon such premises. Except as may be otherwise
directed by the Collateral Agent, all money received from time to time by such Receiver in carrying out its appointment shall be received
in trust for and be paid over to the Collateral Agent, and any surplus shall be applied in accordance with the requirements of applicable
law. Every such Receiver may, in the discretion of the Collateral Agent, be vested with all or any of the rights and powers of the Collateral
Agent.

Section 7.
Application of Proceeds.

 

(a)            If
an Event of Default shall have occurred and be continuing, the Collateral Agent may apply (i) any cash held in the Cash Collateral
Account and (ii) the proceeds of any sale or other disposition of all or any part of the Collateral, in the order of priorities set
forth in Section 7 of the Borrower US Security Agreement and subject to the terms thereof.

 

(b)            In
making the payments and allocations required by this Section, the Collateral Agent may rely upon information supplied to it pursuant to
Section 11(g). All distributions made by the Collateral Agent pursuant to this Section shall be final (except in the case of
manifest error) and the Collateral Agent shall have no duty to inquire as to the application by any Secured Party of any amount distributed
to it.

 

Section 8.
Fees and Expenses; Indemnification.

 

(a)            The
Lien Grantor will forthwith upon demand pay to the Collateral Agent:

 

(i)            the
amount of any taxes that the Collateral Agent may have been required to pay by reason of the Transaction Liens or to free any Collateral
from any other Lien thereon;

 

(ii)           the
amount of any and all reasonable and documented out-of-pocket expenses, including transfer taxes and reasonable and documented fees and
expenses of counsel and other experts, that the Collateral Agent may incur in connection with (x) the administration or enforcement
of the Security Documents, including such expenses as are incurred to preserve the value of the Collateral or the validity, perfection,
rank or value of any Transaction Lien, (y) the collection, sale or other disposition of any Collateral or (z) the exercise by
the Collateral Agent of any of its rights or powers under the Security Documents;

 

(iii)          the
amount of any fees that the Lien Grantor shall have agreed in writing to pay to the Collateral Agent and that shall have become due and
payable in accordance with such written agreement; and

 

(iv)          the
amount required to indemnify the Collateral Agent for, or hold it harmless and defend it against, any loss, liability or expense (including
the reasonable and documented fees and expenses of its counsel and any experts or sub-agents appointed by it hereunder) incurred or suffered
by the Collateral Agent in connection with the Security Documents, except to the extent that such loss, liability or expense arises from
the Collateral Agent’s gross negligence or willful misconduct or a breach of any duty that the Collateral Agent has under this Agreement
(after giving effect to Sections 10 and 11).

 

    	 	16	 

     

    

 

Any such amount not paid to the Collateral Agent on demand will bear
interest for each day thereafter until paid at a rate per annum equal to the sum of 2.00% plus the Base Rate for such day plus the Applicable
Rate that would, in the absence of an Event of Default, be applicable to the Base Rate Loans for such day.

 

(b)            If
any transfer tax, documentary stamp tax or other tax is payable in connection with any transfer or other transaction provided for in the
Security Documents, the Lien Grantor will pay such tax and provide any required tax stamps to the Collateral Agent or as otherwise required
by law.

 

Section 9.
Authority to Administer Collateral.The Lien Grantor irrevocably appoints the Collateral Agent its true and lawful attorney, with full
power of substitution, in the name of the Lien Grantor, any Secured Party or otherwise, for the sole use and benefit of the Secured Parties,
but at the Lien Grantor’s expense, to the extent permitted by law to exercise, at any time and from time to time while an Event
of Default shall have occurred and be continuing, all or any of the following powers with respect to all or any of the Collateral (to
the extent necessary to pay the Secured Obligations in full):

 

(a)            to
demand, sue for, collect, receive and give acquittance for any and all monies due or to become due upon or by virtue thereof,

 

(b)            to
settle, compromise, compound, prosecute or defend any action or proceeding with respect thereto,

Agent were the absolute owner thereof, and

 

(d)            to
extend the time of payment of any or all thereof and to make any allowance or other adjustment with reference thereto;

 

provided that, except in the case of Collateral that is perishable
or threatens to decline speedily in value or is of a type customarily sold on a recognized market, the Collateral Agent will give the
Lien Grantor at least fifteen days’ prior written notice of the time and place of any public sale thereof or the time after which
any private sale or other intended disposition thereof will be made. Any such notice shall contain the information specified in the PPSA;
provided that, if the Collateral Agent fails to comply with this sentence in any respect, its liability for such failure shall
be limited to the liability (if any) imposed on it as a matter of law under the PPSA.

 

    	 	17	 

     

    

 

Section 10.
Limitation on Duty in Respect of Collateral. Beyond the exercise of reasonable care in the custody and preservation thereof, the Collateral
Agent will have no duty as to any Collateral in its possession or control or in the possession or control of any sub-agent or bailee or
any income therefrom or as to the preservation of rights against prior parties or any other rights pertaining thereto. The Collateral
Agent will be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession or control
if such Collateral is accorded treatment substantially equal to that which it accords its own property, and will not be liable or responsible
for any loss or damage to any Collateral, or for any diminution in the value thereof, by reason of any act or omission of any sub-agent
or bailee selected by the Collateral Agent in good faith or by reason of any act or omission by the Collateral Agent pursuant to instructions
from the Administrative Agent, except to the extent that such liability arises from the Collateral Agent’s gross negligence or willful
misconduct.

 

Section 11.
General Provisions Concerning the Collateral Agent.

 

(a)            Authority.
The Collateral Agent is authorized to take such actions and to exercise such powers as are delegated to the Collateral Agent by the terms
of the Security Documents, together with such actions and powers as are reasonably incidental thereto.

 

(b)            Coordination
with Secured Parties. To the extent requested to do so by any Secured Party, the Collateral Agent will promptly notify such Secured
Party of each notice or other communication received by the Collateral Agent hereunder and/or deliver a copy thereof to such Secured Party.
As to any matters not expressly provided for herein (including (i) the timing and methods of realization upon the Collateral and
(ii) the exercise of any power that the Collateral Agent may, but is not expressly required to, exercise under any Security Document),
the Collateral Agent shall act or refrain from acting in accordance with written instructions from the Required Lenders or, in the absence
of such instructions, in accordance with its discretion (subject to the following provisions of this Section).

 

(c)            Rights
and Powers as a Secured Party. The Person serving as the Collateral Agent shall, in its capacity as a Secured Party, have the same
rights and powers as any other Secured Party and may exercise the same as though it were not the Collateral Agent. Such Person and its
Affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower, any of its Subsidiaries
or their respective Affiliates as if it were not the Collateral Agent hereunder.

 

    	 	18	 

     

    

 

(d)            Limited
Duties and Responsibilities. The Collateral Agent shall not have any duties or obligations under the Security Documents except those

fiduciary or other implied duties, regardless of whether an Event of Default has occurred and is continuing, (b) the Collateral Agent
shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers
expressly contemplated by the Security Documents that the Collateral Agent is required in writing to exercise by the Required Lenders,
and (c) except as expressly set forth in the Security Documents, the Collateral Agent shall not have any duty to disclose, and shall
not be liable for any failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to
or obtained by the bank serving as Collateral Agent or any of its Affiliates in any capacity. The Collateral Agent shall not be liable
for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage
of the Lenders as shall be necessary under the circumstances as provided in Section 9.02 of the Credit Agreement) or in the absence
of its own gross negligence or willful misconduct. The Collateral Agent shall not be responsible for the existence, genuineness, or value
of any Collateral or for the validity, perfection, priority, or enforceability of any Transaction Lien, whether impaired by operation
of law or by reason of any action or omission to act on its part under the Security Documents. The Collateral Agent shall be deemed not
to have knowledge of any Event of Default unless and until written notice thereof is given to the Collateral Agent by the Borrower or
a Secured Party, and the Collateral Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement,
warranty or representation made in or in connection with any Security Document, (ii) the contents of any certificate, report or other
document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements
or other terms or conditions set forth in any Security Document, (iv) the validity, enforceability, effectiveness or genuineness

Security Document.

for relying on, any notice, request, certificate, consent, statement, instrument, document, or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. The Collateral Agent also may rely on any statement made to it orally or by telephone
and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Collateral Agent may consult
with legal counsel (who may be counsel for the Borrower or any of its Subsidiaries), independent accountants and other experts selected
by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountant or
expert. The Collateral Agent may rely conclusively on advice from the Administrative Agent as to whether at any time (i) an Event
of Default under the Credit Agreement has occurred and is continuing, (ii) the maturity of the Loans has been accelerated or (iii) any
proposed action is permitted or required by the Credit Agreement.

 

    	 	19	 

     

    

 

(f)            Sub-Agents
and Related Parties. The Collateral Agent may perform any of its duties and exercise any of its rights and powers through one or more
sub-agents appointed by it. The Collateral Agent and any such sub-agent may perform any of its duties and exercise any of its rights and
powers through its Related Parties. The exculpatory provisions of Section 10 and this Section shall apply to any such sub-agent
and to the Related Parties of the Collateral Agent and any such sub-agent.

 

(g)            Information
as to Secured Obligations and Actions by Secured Parties. For all purposes of the Security Documents, including determining the amounts
of the Secured Obligations and whether a Secured Obligation is an Unliquidated Secured Obligation or not, or whether any action has been
taken under any Secured Agreement, the Collateral Agent will be entitled to rely on information from (i) the Administrative Agent
for information as to the Lenders, the Administrative Agent or the Collateral Agent, their Secured Obligations and actions taken by them,
(ii) any Secured Party for information as to its Secured Obligations and actions taken by it, to the extent that the Collateral Agent
has not obtained such information from the foregoing sources, and (iii) the Borrower or any Subsidiary Guarantor, to the extent that
the Collateral Agent has not obtained information from the foregoing sources.

 

(h)            Within
two Business Days after it receives or sends any notice referred to in this subsection, the Collateral Agent shall send to the Administrative
Agent and each Secured Party requesting notice thereof, copies of any notice given by the Collateral Agent to the Lien Grantor, or received
by it from the Lien Grantor; provided that such Secured Party has, at least five Business Days prior thereto, delivered to the
Collateral Agent a written notice (i) stating that it holds one or more Secured Obligations and wishes to receive copies of such
notices and (ii) setting forth its address, facsimile number and e-mail address to which copies of such notices should be sent.

 

(i)             The
Collateral Agent may refuse to act on any notice, consent, direction or instruction from the Administrative Agent or any Secured Parties
or any agent, trustee or similar representative thereof that, in the Collateral Agent’s opinion, (i) is contrary to law or
the provisions of any Security Document, (ii) may expose the Collateral Agent to liability (unless the Collateral Agent shall have
been indemnified, to its reasonable satisfaction, for such liability by the Secured Parties that gave, or instructed the Agent to give,
such notice, consent, direction or instruction) or (iii) is unduly prejudicial to Secured Parties not joining in such notice, consent,
direction or instruction.

(j)             Resignation;
Successor Collateral Agent. Subject to the appointment and acceptance of a successor Collateral Agent as provided in this subsection,
the Collateral Agent may resign at any time by notifying the Secured Parties and the Borrower. Upon any such resignation, the Required
Lenders shall have the right, in consultation with the Lien Grantor, to appoint a successor Collateral Agent. If no successor shall have
been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Collateral Agent
gives notice of its resignation, then the retiring Collateral Agent may, on behalf of the Secured Parties, appoint a successor Collateral
Agent which shall be a bank with an office in the United States, or an Affiliate of any such bank. Upon acceptance of its appointment
as Collateral Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Collateral Agent hereunder, and the retiring Collateral Agent shall be discharged from its duties and obligations
hereunder. The fees payable by the Lien Grantor to a successor Collateral Agent shall be the same as those payable to its predecessor
unless otherwise agreed by the Lien Grantor and such successor. After the Collateral Agent’s resignation hereunder, the provisions
of this Section and Section 10 shall continue in effect for the benefit of such retiring Collateral Agent, its sub-agents and
their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Collateral Agent
was acting as Collateral Agent.

 

Section 12.
Termination of Transaction Liens; Release of Collateral.

 

(a)            The
Transaction Liens shall terminate when all the Release Conditions are satisfied.

 

(b)            The
Transaction Liens (x) with respect to any Pledged Receivables shall terminate when such Receivables have become Transferred Receivables
and (y) with respect to any other Collateral shall terminate upon the sale of such Collateral to a Person other than a Credit Party
in a transaction not prohibited by the Credit Agreement. In each case, such termination shall not require the consent of any Secured Party,
and the Collateral Agent and any third party shall be fully protected in relying on a certificate of the Lien Grantor as to whether any
Pledged Receivables qualify as Transferred Receivables (including whether the transfer thereof is permitted under the Credit Agreement
and this Agreement).

 

(c)            If
the Borrower delivers a certificate pursuant to Section 12(b) stating that any Pledged Receivables qualify as Transferred Receivables,
the Collateral Agent and any third party shall be fully protected in relying on such certificate as conclusive proof that the Transferred
Receivables are not Collateral.

 

(d)            At
any time before the Transaction Liens terminate, the Collateral Agent may, at the written request of the Lien Grantor, (i) release
any Collateral (but not all or substantially all of the Collateral) with the prior written consent of the Required Lenders or (ii) release
all or substantially all of the Collateral with the prior written consent of all the Lenders.

 

(e)            Upon
any termination of a Transaction Lien or release of Collateral, the Collateral Agent will, at the expense of the Lien Grantor, execute
and deliver to the Lien Grantor such documents as the Lien Grantor shall reasonably request to evidence the termination of such Transaction
Lien or the release of such Collateral, as the case may be. Each Secured Party consents to the Collateral Agent’s delivery of, and
hereby directs the Collateral Agent to deliver, such release documents.
