NOW, THEREFORE, in

are hereby acknowledged, the parties hereto agree as follows:


 


1.          Definitions.
All capitalized terms used herein without definitions shall have the respective meanings provided therefor in the Credit Agreement.
The term “State,” as used herein, means the State of Connecticut. All terms defined in the Uniform Commercial Code
of the State and used herein shall have the same definitions herein as specified therein. However, if a term is defined in Article
9 of the Uniform Commercial Code of the State differently than in another Article of the Uniform Commercial Code of the State,
the term has the meaning specified in Article 9. The term “Obligations,” as used herein, shall have the meaning ascribed
to it in the Credit Agreement.


 


2.          Grant
of Security Interest.  The Guarantor hereby grants to the Agent, for the ratable benefit of the Lenders, to secure
the payment and performance in full of all of the Obligations, a security interest in and pledges and assigns the following properties,
assets and rights of the Guarantor, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and
products thereof (all of the same being hereinafter called the “Collateral”): all assets including all personal and
fixture property of every kind and nature, including without limitation all goods (including inventory, equipment and any accessions
thereto), instruments (including promissory notes), documents, accounts (including health-care-insurance receivables), chattel
paper (whether tangible or electronic), deposit accounts, letter-of-credit rights (whether or not the letter of credit is evidenced
by a writing), commercial tort claims, securities and all other investment property, supporting obligations, any other contract
rights or rights to the payment of money, insurance claims and proceeds, all general intangibles (including all payment intangibles),
and all products and proceeds of the foregoing. Notwithstanding anything herein to the contrary, the term “Collateral”
shall not include more than 65% of the equity interests of a first-tier Foreign Subsidiary (or more than 65% of the equity interests
of a Domestic Subsidiary whose sole assets are the equity interests of Foreign Subsidiaries) or to the extent not yet paid to the
Guarantor or such Domestic Subsidiary to more than the corresponding proportion of dividends, distributions, interest and other
payments with respect to more than 65% of such equity interests (such excluded assets herein called the “Excluded Assets”).
The Agent acknowledges that the attachment of its security interest in any commercial tort claim as original collateral is subject
to the Guarantor’s compliance with § 4.7.

3.          Authorization
to File Financing Statements. The Guarantor hereby irrevocably authorizes the Agent at any time and from time to time to
file in any filing office in any Uniform Commercial Code jurisdiction any initial financing statements and amendments thereto that
(a) indicate the Collateral (i) as all assets or, as the case may be, all personal property of the Guarantor or words of similar
effect, regardless of whether any particular asset comprised in the Collateral falls within the scope of Article 9 of the Uniform
Commercial Code of the State or such jurisdiction specifically excluding, however, the Excluded Assets, or (ii) as being of an
equal or lesser scope or with greater detail, and (b) provide any other information required by part 5 of Article 9 of the Uniform
Commercial Code of the State or such other jurisdictions for the sufficiency or filing office acceptance of any financing statement
or amendment, including (i) whether the Guarantor is an organization, the type of organization and any organizational identification
number issued to the Guarantor and, (ii) in the case of a financing statement filed as a fixture filing or indicating Collateral
as extracted collateral or timber to be cut, a sufficient description of real property to which the Collateral relates. The Guarantor
agrees to furnish any such information to the Agent promptly upon the Agent’s request. The Guarantor also ratifies its authorization
for the Agent to have filed in any Uniform Commercial Code jurisdiction any like initial financing statements or amendments thereto
if filed prior to the date hereof.


 


4.          Other
Actions. Further to insure the attachment, perfection and first priority of, and the ability of the Agent to enforce,
the Agent’s security interest in the Collateral, the Guarantor agrees, in each case at the Guarantor’s expense, to
take the following actions with respect to the following Collateral and without limitation on the Guarantor’s other obligations
contained in this Agreement:


 


4.1.       Promissory
Notes and Tangible Chattel Paper. If the Guarantor shall, now or at any time hereafter, hold or acquire any promissory
notes or any tangible chattel paper individually having a face value in excess of $2,500,000 (each, a “Material Note”
or “Material Tangible Chattel Paper”, as the case may be), the Guarantor shall forthwith endorse, assign and deliver
to the Agent each such Material Note or Material Chattel Paper, as the case may be, and, in each case of a required endorsement,
assignment and delivery, accompanied by such instruments of transfer or assignment duly executed in blank as the Agent may from
time to time specify.


 


4.2.       Deposit
Accounts. For each deposit account that the Guarantor now or at any time hereafter opens or maintains, the Guarantor shall,
at the Agent’s request and option, pursuant to an agreement in form and substance reasonably satisfactory to the Agent, either
(a) cause the depositary bank to agree to comply, without further consent of the Guarantor, at any time with instructions from
the Agent to such depositary bank directing the disposition of funds from time to time credited to such deposit account, or (b)
arrange for the Agent to become the customer of the depositary bank with respect to the deposit account, with the Guarantor being
permitted, only with the consent of the Agent, to exercise rights to withdraw funds from such deposit account. The Agent agrees
with the Guarantor that the Agent shall not give any such instructions or withhold any withdrawal rights from the Guarantor, unless
an Event of Default has occurred and is continuing, or, if effect were given to any withdrawal not otherwise permitted by the Loan
Documents, would occur. The provisions of this paragraph shall not apply to (i) any deposit account for which the Guarantor, the
depositary bank and the Agent have entered into a cash collateral agreement specially negotiated among the Guarantor, the depositary
bank and the Agent for the specific purpose set forth therein, (ii) a deposit account for which the Agent is the depositary bank
and is in automatic control, and (iii) any deposit accounts specially and exclusively used for payroll, payroll taxes and other
employee wage and benefit payments to or for the benefit of the Guarantor’s employees. Nothing in this Section 4.2 shall
be construed to limit or otherwise derogate in any way the Guarantor’s obligations under Section 6.15 of the Credit Agreement.


 




    	3



    	 



    

 


4.3.       Investment
Property. Subject to the limitations set forth in Section 2 hereof, if the Guarantor shall now or at any time hereafter
hold or acquire any certificated securities of any Subsidiary, the Guarantor shall forthwith endorse, assign and deliver the same
to the Agent, accompanied by such instruments of transfer or assignment duly executed in blank as the Agent may from time to time
specify. If any securities now or hereafter acquired by the Guarantor are (a) (i) uncertificated or (ii) certificated and issued
by a Person other than a Subsidiary, (b) issued to the Guarantor or its nominee directly by the issuer thereof, and (c) have a
principal amount or value in excess of $5,000,000 in the aggregate with respect to any one issuer (each a “Material Security”),
the Guarantor shall promptly notify the Agent thereof and, at the Agent’s request and option pursuant to an agreement in
a form and substance reasonably satisfactory to the Agent, either (A) cause the issuer to agree to comply, without further consent
of the Guarantor, or such nominee, at any time with instructions from the Agent as to each Material Security or (B) arrange for
the Agent to become the registered owner of the Material Securities. Subject to the limitations set forth in Section 2 hereof,
if any securities, whether certificated or uncertificated, or other investment property now or hereafter acquired by the Guarantor
is held by the Guarantor or its nominee through a securities intermediary or commodity intermediary and constitute a Material Security,
the Guarantor shall promptly notify the Agent thereof and, at the Agent’s request and option, the Guarantor shall, pursuant
to an agreement in form and substance reasonably satisfactory to the Agent, either (i) cause such securities intermediary or (as
the case may be) commodity intermediary to agree to comply, in each case without further consent of the Guarantor or such nominee,
at any time with entitlement orders or other instructions from the Agent to such securities intermediary as to such a Material
Security, or (as the case may be) to apply any value distributed on account of any commodity contract as directed by the Agent
to such commodity intermediary, or (ii) in the case of a Material Security held through a securities intermediary, arrange for
the Agent to become the entitlement holder with respect to such a Material Security, with the Guarantor being permitted, only with
the consent of the Agent, to exercise rights to withdraw or otherwise deal with such investment property. The Agent agrees with
the Guarantor that the Agent shall not give any such entitlement orders or instructions or directions to any such issuer, securities
intermediary or commodity intermediary, and shall not withhold its consent to the exercise of any withdrawal or dealing rights
by the Guarantor, unless an Event of Default has occurred and is continuing, or, after giving effect to any such investment and
withdrawal rights not otherwise permitted by the Loan Documents, would occur. The provisions of this paragraph shall not apply
to any financial assets credited to a securities account for which the Agent is the securities intermediary.


 


4.4.       Collateral
in the Possession of a Bailee. If any Collateral having an aggregate value of more than $1,000,000 is now or at any time
hereafter in the possession of a bailee at a particular location, the Guarantor shall promptly notify the Agent thereof and, at
the Agent’s request and option, shall use reasonable best efforts to obtain an acknowledgement from the bailee, in form and
substance reasonably satisfactory to the Agent, that the bailee holds such Collateral for the benefit of the Agent and such bailee’s
agreement to comply, without further consent of the Guarantor, at any time with instructions of the Agent as to such Collateral.
The Agent agrees with the Guarantor that the Agent shall not give any such instructions unless an Event of Default has occurred
and is continuing or would occur after taking into account any action by the Guarantor with respect to the bailee.


 




    	4



    	 



    

 


4.5.       Electronic
Chattel Paper and Transferable Records. If the Guarantor, now or at any time hereafter, holds or acquires an interest in
any electronic chattel paper, any electronic document or any “transferrable record,” individually having a face value
in excess of $2,500,000 (each a “Material Electronic Paper”), the Guarantor shall (i) promptly notify the Agent thereof
and, (ii) at the request and option of the Agent, take such action as the Agent may reasonably request to vest in the Agent control
of such Material Electronic Paper, under Section 9-105 of the Uniform Commercial Code of the State or any other relevant jurisdiction,
Section 7-106 of the Uniform Commercial Code of the State or any other relevant jurisdiction, Section 201 of the federal Electronic
Signatures in Global and National Commerce Act or Section 16 of the Uniform Electronic Transactions Act, as so in effect in such
jurisdiction, as applicable. The Agent agrees with the Guarantor that the Agent will arrange, pursuant to procedures satisfactory
to the Agent and so long as such procedures will not result in the Agent’s loss of control, for the Guarantor to make alterations
to the electronic chattel paper, electronic document or transferable record permitted under UCC Section 9-105, UCC Section 7-106,
or, as the case may be, Section 201 of the federal Electronic Signatures in Global and National Commerce Act or Section 16 of the
Uniform Electronic Transactions Act for a party in control to make without loss of control, unless an Event of Default has occurred
and is continuing or would occur after taking into account any action by the Guarantor with respect to such electronic chattel
paper, electronic document or transferrable record. The provisions of this Section 4.6 relating to electronic documents and “control”
under UCC Section 7-106 apply in the event that the 2003 revisions to Article 7, with amendments to Article 9, of the Uniform Commercial
Code, in substantially the form approved by the American Law Institute and the National Conference of Commissioners on Uniform
State Laws, are now or hereafter adopted and become effective in the State or in any other relevant jurisdiction.


 


4.6.       Letter-of-Credit
Rights. If the Guarantor is, now or at any time hereafter, a beneficiary under a letter of credit now or hereafter individually
having a maximum amount that may be drawn in excess of $2,500,000 (each, a “Material Letter of Credit”), the Guarantor
shall promptly notify the Agent thereof and, at the request and option of the Agent, the Guarantor shall, pursuant to an agreement
in form and substance satisfactory to the Agent, either (A) arrange for the issuer and any confirmer or other nominated person
of each such Material Letter of Credit, to consent to an assignment to the Agent of the proceeds of such Material Letter of Credit
or (B) arrange for the Agent to become the transferee beneficiary of such Material Letter of Credit.


 


4.7        Commercial
Tort Claims. If the Guarantor shall now or at any time hereafter hold or acquire a commercial tort claim with respect to
which the Guarantor has commenced legal action by filing a lawsuit in court and having a value reasonably estimated by the Guarantor
to be in excess of $5,000,000, the Guarantor shall promptly notify the Agent in a writing signed by the Guarantor of the particulars
thereof, and grant to the Agent in such writing a security interest therein and in the proceeds thereof, all upon the terms of
this Agreement, with such writing to be in form and substance satisfactory to the Agent. Such Notice shall be deemed to be an amendment
to the Guarantor’s Perfection Certificate with respect to such commercial tort claim.


 




    	5



    	 



    

 


4.8.       Other
Actions as to any and all Collateral. The Guarantor further agrees, upon request of the Agent and at the Agent’s
option, to take any and all other actions as the Agent may reasonably determine to be necessary or useful for the attachment, perfection
and first priority of (subject, however, to Liens permitted under the Credit Agreement), and the ability of the Agent to enforce,
the Agent’s security interest in any and all of the Collateral, including, without limitation, (a) executing, delivering
and, where appropriate, filing financing statements and amendments relating thereto under the Uniform Commercial Code, to the extent,
if any, that the Guarantor’s signature thereon is required therefor, (b) causing the Agent’s name to be noted as secured
party on any certificate of title for a titled good if such notation is a condition to attachment, perfection or priority of, or
ability of the Agent to enforce, the Agent’s security interest in such Collateral, (c) complying with any provision of any
statute, regulation or treaty of the United States as to any Collateral if compliance with such provision is a condition to attachment,
perfection or priority of, or ability of the Agent to enforce, the Agent’s security interest in such Collateral, (d) obtaining
governmental and other third party waivers, consents and approvals in form and substance satisfactory to the Agent, including,
without limitation, any consent of any licensor, lessor or other person obligated on Collateral, (e) using reasonable best efforts
to obtain waivers from mortgagees and landlords in form and substance satisfactory to the Agent and in accordance with the terms
of the Credit Agreement, and (f) taking all actions under any earlier versions of the Uniform Commercial Code or under any other
law, as reasonably determined by the Agent to be applicable in any relevant Uniform Commercial Code or other jurisdiction, including
any foreign jurisdiction.


 


5.          Relation
to Other Security Documents. The provisions of this Agreement supplement the provisions of any real estate mortgage or
deed of trust, if any, granted by the Guarantor to the Agent and which secures the payment or performance of any of the Obligations.
Nothing contained in any such real estate mortgage or deed of trust shall derogate from any of the rights or remedies of the Agent
hereunder.

and Warranties Concerning Guarantor’s Legal Status. The Guarantor represents and warrants to the Agent as follows:
(a) the Guarantor’s exact legal name is that indicated on the signature page hereof, (b) the Guarantor is an organization

10.        Insurance.


 


10.1.     Maintenance
of Insurance. The Guarantor will maintain with financially sound and reputable insurers insurance with respect to its properties
and business against such casualties and contingencies as shall be in accordance with general practices of businesses engaged in
similar activities in similar geographic areas. Such insurance shall be in such minimum amounts that the Guarantor will not be
deemed a co-insurer under applicable insurance laws, regulations and policies and otherwise shall be in such amounts, contain such
terms, be in such forms and be for such periods as may be reasonably satisfactory to the Agent. In addition, all such property
casualty insurance shall be payable to the Agent as loss payee under a loss payee clause reasonably acceptable to the Agent. Without
limiting the foregoing, the Guarantor will (i) keep all of its physical property insured with casualty or physical hazard insurance
on an “all risks” basis, with broad form flood and earthquake coverages and electronic data processing coverage, with
a full replacement cost endorsement and an “agreed amount” clause in an amount equal to 100% of the full replacement
cost of such property, (ii) maintain all such workers’ compensation or similar insurance as may be required by law and (iii)
maintain, in amounts and with deductibles equal to those generally maintained by businesses engaged in similar activities in similar
geographic areas, general public liability insurance against claims of bodily injury, death or property damage occurring, on, in
or about the properties of the Guarantor; business interruption insurance; and product liability insurance.


 


10.2.     Insurance
Proceeds. The proceeds of any casualty insurance in respect of any casualty loss of any of the Collateral shall, subject
to the rights, if any, of other parties with an interest having priority in the property covered thereby, (i) so long as no Event
of Default has occurred and is continuing, be disbursed to the Guarantor for direct application by the Guarantor to the repair
or replacement of the Guarantor’s property so damaged or destroyed, with any excess proceeds to be retained by the Guarantor,
and (ii) if an Event of Default has occurred and is continuing, be distributed to the Agent to be held by the Agent as cash collateral
for the Obligations. The Agent may, at its sole option, disburse from time to time all or any part of such proceeds so held as
cash collateral, upon such terms and conditions as the Agent may reasonably prescribe, for direct application by the Guarantor
solely to the repair or replacement of the Guarantor’s property so damaged or destroyed, or the Agent may apply all or any
part of such proceeds to the Obligations.


 




    	8



    	 



    

 


10.3.     Continuation
of Insurance. All policies of insurance shall provide for at least thirty (30) days prior written cancellation notice to
the Agent. In the event of failure by the Guarantor to provide and maintain insurance as herein provided, the Agent may, at its
option, provide such insurance and charge the amount thereof to the Guarantor. The Guarantor shall furnish the Agent with certificates
of insurance and policies evidencing compliance with the foregoing insurance provision.


 


11.        Collateral
Protection Expenses: Preservation of Collateral.


 


11.1.     Expenses
Incurred by Agent. In the Agent’s discretion, if the Guarantor fails to do so, the Agent may discharge taxes and
other encumbrances at any time levied or placed on any of the Collateral, make repairs thereto, maintain any of the Collateral,
and pay any necessary filing fees or insurance premiums. The Guarantor agrees to reimburse the Agent on demand for all expenditures
so made. The Agent shall have no obligation to the Guarantor to make any such expenditures, nor shall the making thereof be construed
as a waiver or cure of any Default or Event of Default.


 


11.2.     Agent’s
Obligations and Duties. Anything herein to the contrary notwithstanding, the Guarantor shall remain obligated and liable
under each contract or agreement comprised in the Collateral to be observed or performed by the Guarantor thereunder. The Agent
shall not have any obligation or liability under any such contract or agreement by reason of, or arising out of, this Agreement
or the receipt by the Agent of any payment relating to any of the Collateral, nor shall the Agent be obligated in any manner to
perform any of the obligations of the Guarantor under, or pursuant to, any such contract or agreement, to make inquiry as to the
nature or sufficiency of any payment received by the Agent in respect of the Collateral or as to the sufficiency of any performance
by any party under any such contract or agreement, to present or file any claim, to take any action to enforce any performance
or to collect the payment of any amounts which may have been assigned to the Agent or to which the Agent may be entitled at any
time or times. The Agent’s sole duty with respect to the custody, safe keeping and physical preservation of the Collateral
in its possession, under §9-207 of the Uniform Commercial Code of the State or otherwise, shall be to deal with such Collateral
in the same manner as the Agent deals with similar property for its own account.


 


12.        Securities
and Deposits. The Agent may at any time following the occurrence and during the continuance of an Event of Default, at
its option, transfer to itself or any nominee any securities constituting Collateral, receive any income thereon and hold such
income as additional Collateral or apply it to the Obligations. Whether or not any Obligations are due, the Agent may following
the occurrence and during the continuance of an Event of Default demand, sue for, collect, or make any settlement or compromise
which it deems desirable with respect to the Collateral. Regardless of the adequacy of Collateral or any other security for the
Obligations, any deposits or other sums at any time credited by or due from the Agent to the Guarantor may at any time during the
continuance of an Event of Default be applied to, or set off against, any of the Obligations then due and owing.


 




    	9



    	 



    

 


13.        Notification
to Account Debtors and Other Persons Obligated on Collateral. If an Event of Default shall have occurred and be continuing,
the Guarantor shall, at the request and option of the Agent, notify account debtors and other persons obligated on any of the Collateral
of the security interest of the Agent in any account, chattel paper, general intangible, instrument or other Collateral and that
payment thereof is to be made directly to the Agent or to any financial institution designated by the Agent as the Agent’s
agent therefor, and the Agent may itself, if an Event of Default shall have occurred and be continuing, without notice to or demand
upon the Guarantor, so notify account debtors and other persons obligated on Collateral, which notice may include the provision
to such account debtors and other persons of an accounts receivable letter which, if provided, may be (a) substantially in the
form attached hereto as Exhibit B (Agent having required Guarantor to execute an undated accounts receivable letter in the
form of Exhibit B attached hereto which Agent agrees to hold and not release unless Agent is permitted to send such letter
as provided in this Section 13), or (b) in another form executed by Guarantor upon request of Agent. After the making of such a
request or the giving of any such notification, the Guarantor shall hold any proceeds of collection of accounts, chattel paper,
general intangibles, instruments and other Collateral received by the Guarantor as trustee for the Agent without commingling the
same with other funds of the Guarantor and shall turn the same over to the Agent in the identical form received, together with
any necessary endorsements or assignments. The Agent shall apply the proceeds of collection of accounts, chattel paper, general
intangibles, instruments and other Collateral received by the Agent to the Obligations, such proceeds to be immediately credited
after final payment in cash or other immediately available funds of the items giving rise to them.


 


14.        Power
of Attorney.


 


14.1.     Appointment
and Powers of Agent. The Guarantor hereby irrevocably constitutes and appoints the Agent and any officer or agent thereof,
with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place
and stead of the Guarantor or in the Agent’s own name, for the purpose of carrying out the terms of this Agreement, to take
any and all appropriate action and to execute any and all documents and instruments that may be necessary or useful to accomplish
the purposes of this Agreement and, without limiting the generality of the foregoing, hereby gives said attorneys the power and
right, on behalf of the Guarantor, without notice to or assent by the Guarantor, to do the following:


 


(a)         upon
the occurrence and during the continuance of an Event of Default, generally to sell, transfer, pledge, make any agreement with
respect to or otherwise dispose of or deal with any of the Collateral in such manner as is consistent with the Uniform Commercial
Code of the State and as fully and completely as though the Agent were the absolute owner thereof for all purposes, and to do,
at the Guarantor’s expense, at any time, or from time to time, all acts and things which the Lender deems necessary or useful
to protect, preserve or realize upon the Collateral and the Agent’s security interest therein, in order to effect the intent
of this Agreement, all no less fully and effectively as the Guarantor might do, including, without limitation, (i) the filing and
prosecuting of registration and transfer applications with the appropriate federal, state or local agencies or authorities with
respect to trademarks, copyrights and patentable inventions and processes, (ii) upon written notice to the Guarantor, the exercise
of voting rights with respect to voting securities, which rights may be exercised, if the Agent so elects, with a view to causing
the liquidation of assets of the issuer of any such securities and (iii) the execution, delivery and recording, in connection with
any sale or other disposition of any Collateral, of the endorsements, assignments or other instruments of conveyance or transfer
with respect to such Collateral; and


 




    	10



    	 



    

 


(b)         to
the extent that the Guarantor’s authorization given in §3 is not sufficient, to file such financing statements with
respect hereto, with or without the Guarantor’s signature, or a photocopy of this Agreement in substitution for a financing
statement, as the Agent may deem appropriate and to execute in the Guarantor’s name such financing statements and amendments
thereto and continuation statements which may require the Guarantor’s signature.


 


14.2.     Ratification
by Guarantor. To the extent permitted by law, the Guarantor hereby ratifies all that said attorneys shall lawfully do or
cause to be done by virtue hereof. This power of attorney is a power coupled with an interest and is irrevocable.


 


14.3.     No
Duty on Agent. The powers conferred on the Agent hereunder are solely to protect its interests in the Collateral and shall
not impose any duty upon it to exercise any such powers. The Agent shall be accountable only for the amounts that it actually receives
as a result of the exercise of such powers, and neither it nor any of its officers, directors, employees or agents shall be responsible
to the Guarantor for any act or failure to act, except for the Agent’s own gross negligence or willful misconduct.


 


15.        Rights
and Remedies. If an Event of Default shall have occurred and be continuing, the Agent, without any other notice to or demand
upon the Guarantor, shall have in any jurisdiction in which enforcement hereof is sought, in addition to all other rights and remedies,
the rights and remedies of a secured party under the Uniform Commercial Code of the State and of such jurisdiction and any additional
rights and remedies as may be provided to a secured party in any jurisdiction in which Collateral is located, including, without
limitation, the right to take possession of the Collateral, and for that purpose the Agent may, so far as the Guarantor can give
authority therefor, enter upon any premises on which the Collateral may be situated and remove the same therefrom. The Agent may
in its discretion require the Guarantor to assemble all or any part of the Collateral at such location or locations within the
jurisdiction(s) of the Guarantor’s principal office(s) or at such other locations as the Agent may reasonably designate.
Unless the Collateral is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized
market, the Agent shall give to the Guarantor at least ten (10) Business Days prior written notice of the time and place of any
public sale of Collateral or of the time after which any private sale or any other intended disposition is to be made. The Guarantor
hereby acknowledges that ten (10) Business Days prior written notice of such sale or sales shall be reasonable notice. In addition,
the Guarantor waives any and all rights that it may have to a judicial hearing in advance of the enforcement of any of the Agent’s
rights and remedies hereunder, including, without limitation, its right following an Event of Default to take immediate possession
of the Collateral and to exercise its rights and remedies with respect thereto.

16.        Standards
for Exercising Rights and Remedies. To the extent that applicable law imposes duties on the Agent to exercise remedies
in a commercially reasonable manner, the Guarantor acknowledges and agrees that it is not commercially unreasonable for the Agent
(a) to fail to incur expenses reasonably deemed significant by the Agent to prepare Collateral for disposition or otherwise to
fail to complete raw material or work in process into finished goods or other finished products for disposition, (b) to fail to
obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail
to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of,
(c) to fail to exercise collection remedies against account debtors or other persons obligated on Collateral or to fail to remove
liens or encumbrances on or any adverse claims against Collateral, (d) to exercise collection remedies against account debtors
and other persons obligated on Collateral directly or through the use of collection agencies and other collection specialists,
(e) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral
is of a specialized nature, (f) to contact other persons, whether or not in the same business as the Guarantor, for expressions
of interest in acquiring all, or any portion of, the Collateral, (g) to hire one or more professional auctioneers to assist in
the disposition of Collateral, whether or not the Collateral is of a specialized nature, (h) to dispose of Collateral by utilizing
Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability
of doing so, or that match buyers and sellers of assets, (i) to dispose of assets in wholesale rather than retail markets, (j)
to disclaim disposition warranties, (k) to purchase insurance or credit enhancements to insure the Agent against risks of loss,
collection or disposition of Collateral or to provide to the Agent a guaranteed return from the collection or disposition of Collateral,
or (l) to the extent deemed appropriate by the Agent, to obtain the services of brokers, investment bankers, consultants and other
professionals to assist the Agent in the collection, or disposition of, any of the Collateral. The Guarantor acknowledges that
the purpose of this §16 is to provide non-exhaustive indications of what actions or omissions by the Agent would fulfill the
Agent’s duties under the Uniform Commercial Code of the State or any other relevant jurisdiction in the Agent’s exercise
of remedies against the Collateral and that other actions or omissions by the Agent shall not be deemed to fail to fulfill such
duties solely on account of not being indicated in this §16. Without limitation upon the foregoing, nothing contained in this
§16 shall be construed to grant any rights to the Guarantor or to impose any duties on the Agent that would not have been
granted or imposed by this Agreement or by applicable law in the absence of this §16.


 


17.        No
Waiver by Agent, etc. The Agent shall not be deemed to have waived any of its rights and remedies in respect of the Obligations
or the Collateral unless such waiver shall be in writing and signed by the Agent. No delay or omission on the part of the Agent
in exercising any right or remedy shall operate as a waiver of such right or remedy or any other right or remedy. A waiver on any
one occasion shall not be construed as a bar to or waiver of any right or remedy on any future occasion. All rights and remedies
of the Agent with respect to the Obligations or the Collateral, whether evidenced hereby or by any other instrument or papers,
shall be cumulative and may be exercised singularly, alternatively, successively or concurrently at such time or at such times
as the Agent deems expedient.

18.        Suretyship
Waivers by Guarantor. Except as may be otherwise specifically provided in the Credit Agreement, the Guarantor waives demand,
notice, protest, notice of acceptance of this Agreement, notice of loans made, credit extended, Collateral received or delivered
or other action taken in reliance hereon and all other demands and notices of any description. With respect to both the Obligations
and the Collateral, the Guarantor assents to any extension or postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of or failure to perfect any security interest in any Collateral, to the addition or release
of any party or person primarily or secondarily liable, to the acceptance of partial payment thereon and the settlement, compromising
or adjusting of any thereof, all in such manner and at such time or times as the Agent may deem advisable. The Agent shall have
no duty as to the collection or protection of the Collateral or any income therefrom, the preservation of rights against prior
parties, or the preservation of any rights pertaining thereto beyond the safe custody thereof as set forth in Section 11.2. The
Guarantor further waives any and all other suretyship defenses.


 


19.        Marshalling.
The Agent shall not be required to marshal any present or future collateral security (including but not limited to the Collateral)
for, or other assurances of payment of, the Obligations or any of them or to resort to such collateral security or other assurances
of payment in any particular order, and all of its rights and remedies hereunder and in respect of such collateral security and
other assurances of payment shall be cumulative and in addition to all other rights and remedies, however existing or arising.
To the extent that it lawfully may, the Guarantor hereby agrees that it will not invoke any law relating to the marshalling of
collateral which might cause delay in or impede the enforcement of the Agent’s rights and remedies under this Agreement or
under any other instrument creating or evidencing any of the Obligations or under which any of the Obligations is outstanding or
by which any of the Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, the
Guarantor hereby irrevocably waives the benefits of all such laws.


 


20.        Proceeds
of Dispositions; Expenses. The Guarantor shall pay to the Agent on demand amounts equal to any and all reasonable expenses,
including, without limitation, reasonable attorneys’ fees and disbursements, incurred or paid by the Agent in protecting,
preserving or enforcing the Agent’s rights and remedies under, or in respect of, any of the Obligations or any of the Collateral.
After deducting all of said expenses, the residue of any proceeds of collection or sale or other disposition of Collateral shall,
to the extent actually received in cash, be applied to the payment of the Obligations in such order or preference as the Agent
may determine or in such order or preference as is provided in the Credit Agreement, proper allowance and provision being made
for any Obligations not then due. Upon the final payment and satisfaction in full of all of the Obligations and after making any
payments required by Sections 9-608(a)(1)(C) or 9-615(a)(3) of the Uniform Commercial Code of the State, any excess shall be returned
to the Guarantor. In the absence of final payment and satisfaction in full of all of the Obligations, the Guarantor shall remain
liable for any deficiency.


 


21.        Overdue
Amounts. Until paid, all amounts which become due and payable by the Guarantor hereunder shall be a debt secured by the
Collateral and if not otherwise paid within any applicable grace period after the same becomes due shall bear, whether before or
after judgment, interest at the rate of interest for overdue principal set forth in the Credit Agreement.

22.         Governing
Law; Consent to Jurisdiction. THIS AGREEMENT IS INTENDED TO TAKE EFFECT AND SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF CONNECTICUT. The Guarantor agrees that any action or claim arising out of any dispute in connection
with this Agreement, any rights or obligations hereunder or the performance or enforcement of such rights or obligations may be
brought in the courts of the State of Connecticut or any federal court sitting therein and consents to the non-exclusive jurisdiction
of such court and to service of process in any such suit being made upon the Guarantor by certified or registered mail at the address
specified in the Credit Agreement. The Guarantor hereby waives any objection that it may now or hereafter have to the venue of
any such suit or any such court or that such suit is brought in an inconvenient forum.


 


23.         Waiver
of Jury Trial. EACH PARTY HERETO WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT
TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE
PERFORMANCE OR ENFORCEMENT OF ANY SUCH RIGHTS OR OBLIGATIONS. Except as prohibited by law, the Guarantor waives any right which
it may have to claim or recover in any litigation referred to in the preceding sentence any special, exemplary, punitive or consequential
damages or any damages other than, or in addition to, actual damages. The Guarantor (i) certifies that neither the Agent nor any
representative, agent or attorney of the Agent has represented, expressly or otherwise, that the Agent would not, in the event
of litigation, seek to enforce the foregoing waivers or other waivers contained in this Agreement and (ii) acknowledges that, in
entering into the Credit Agreement and the other Loan Documents to which the Agent is a party, the Agent is relying upon, among
other things, the waivers and certifications contained in this Section 23.


 


24.         Miscellaneous.
The headings of each section of this Agreement are for convenience only and shall not define or limit the provisions thereof. This
Agreement and all rights and obligations hereunder shall be binding upon the Guarantor and its successors and assigns, and shall
inure to the benefit of the Agent and its successors and assigns permitted pursuant to the Credit Agreement. If any term of this
Agreement shall be held to be invalid, illegal or unenforceable, the validity of all other terms hereof shall in no way be affected
thereby, and this Agreement shall be construed and be enforceable as if such invalid, illegal or unenforceable term had not been
included herein. The Guarantor acknowledges receipt of a copy of this Agreement.

25.         PREJUDGMENT
REMEDY WAIVER.


 


THE GUARANTOR HEREBY
REPRESENTS, WARRANTS AND ACKNOWLEDGES THAT THE FINANCING EVIDENCED HEREBY IS A COMMERCIAL TRANSACTION WITHIN THE MEANING OF CHAPTER
903a OF THE CONNECTICUT GENERAL STATUTES, AS AMENDED. THE GUARANTOR HEREBY WAIVES ITS RIGHT TO NOTICE AND PRIOR COURT HEARING OR
COURT ORDER UNDER CONNECTICUT GENERAL STATUTES SECTIONS 52-278a ET. SEQ. AS AMENDED OR UNDER ANY OTHER STATE OR FEDERAL
LAW WITH RESPECT TO ANY AND ALL PREJUDGMENT REMEDIES THE AGENT MAY EMPLOY TO ENFORCE ITS RIGHTS AND REMEDIES HEREUNDER AND UNDER
THE OTHER LOAN DOCUMENTS. MORE SPECIFICALLY, THE GUARANTOR ACKNOWLEDGES THAT UPON THE OCCURRENCE AND DURING THE CONTINUANCE OF
AN EVENT OF DEFAULT THE AGENT’S ATTORNEY MAY, PURSUANT TO, AND IN ACCORDANCE WITH, CONN. GEN. STAT. §52-278f, ISSUE
A WRIT FOR A PREJUDGMENT REMEDY WITHOUT SECURING A COURT ORDER, PROVIDED THE COMPLAINT SHALL SET FORTH A COPY OF THIS WAIVER. THE
GUARANTOR ACKNOWLEDGES AND RESERVES ITS RIGHT TO NOTICE AND A HEARING SUBSEQUENT TO THE ISSUANCE OF A WRIT FOR PREJUDGMENT REMEDY
AS AFORESAID AND THE AGENT ACKNOWLEDGES THE GUARANTOR’S RIGHT TO SAID HEARING SUBSEQUENT TO THE ISSUANCE OF SAID WRIT. THE
GUARANTOR FURTHER WAIVES ITS RIGHTS TO REQUEST THAT THE AGENT POST A BOND, WITH OR WITHOUT SURETY, TO PROTECT GUARANTOR AGAINST
DAMAGES THAT MAY BE CAUSED BY ANY PREJUDGMENT REMEDY SOUGHT OR OBTAINED BY THE AGENT.


 


26.         Amendments.
Neither this Agreement nor any term hereof may be amended, waived, discharged or terminated, except by a written instrument signed
by the Guarantor and the Agent.


 


27.         Electronic
Self-Help Authorization. Upon and during the continuance of an Event of Default, the Agent shall have, in addition
to all other rights and remedies contained in this Agreement, (which the Guarantor, and, by becoming bound by the Obligations or
this Agreement, all other obligors, guarantors and any new debtors accept and agree upon), the right to locate, disable or to take
possession of the Collateral by electronic, digital, magnetic or wireless optical electromagnetic or similar means after giving
any notices required under applicable law.


 


28.       Termination.
At such time as all of the Obligations (other than contingent indemnification obligations for which no claim has been asserted)
have been finally paid and satisfied in full and the Commitment has been irrevocably terminated, this Agreement shall terminate
and Agent shall, upon written request and at the expense of Guarantor, execute and deliver to Guarantor all documents and other
instruments as may be necessary or proper to evidence the termination of Agent’s security interest in the Collateral and
Agent shall return to Guarantor any Collateral then in Agent’s possession.
