(j)          Mergers;
Acquisitions. Other than Beacon Acquisition in accordance with the Beacon Acquisition Documents, Guarantor will not, and will
not permit any other Beacon Loan Party to, merge or consolidate or be merged or consolidated with or into any other Person, or
otherwise reorganize, liquidate or wind-up or dissolve itself.

 

(k)          Liability
Insurance. Subject to Section 3.2(o), Guarantor will, and will cause each other Beacon Loan Party to, at all times,
maintain in full force and effect such liability insurance with respect to its activities and business interruption, product liability
and other insurance as may be reasonably required by Bank, such insurance to be provided by insurer(s) reasonably acceptable to
Bank. Such insurance shall name Bank as an additional insured containing a severability of interest/cross-liability endorsement
acceptable to Bank.

Insurance. Guarantor will, and will cause each other Beacon Loan Party to, insure all of its real and personal property, including
the Loan Collateral, as applicable, against loss or damage by fire, theft, burglary, pilferage, loss in transit and such other
extended coverage hazards as Bank shall specify in amounts and under policies by insurers reasonably acceptable to Bank. The policies
or a certificate thereof signed by the insurer evidencing that such insurance coverage is in effect for periods of not less than
one year (as measured from the date of renewal) shall be delivered to Bank within five Business Days after the issuance of the
policies to the applicable Beacon Loan Party and after each renewal thereof. All premiums thereon shall be paid by the Beacon Loan
Parties when due so as to keep such insurance in full force and effect at all times. With respect to any policy insuring any Loan
Collateral, such policy shall name Bank (and no other party, except to the extent of Permitted Liens) as loss payee and, as appropriate,
mortgagee under a New York standard mortgagee clause or other similar clause acceptable to Bank and shall provide that such policy
may not be amended or canceled without 30 days prior written notice to Bank. If any Beacon Loan Party fails to do so, Bank may
(but shall not be required to) procure such insurance with respect to any of the Loan Collateral, and all such costs and expenses
incurred by Bank shall be payable by Guarantor on demand and secured by the Loan Collateral provided by any Beacon Loan Party.

the Beacon Texas Facility’s BQ-9000 accreditation has been fully reinstated.

 

(o)          Certificate
of Liability Insurance. On or before the date that is 30 days after the Effective Date, Guarantor will deliver to Bank evidence,
in form and substance satisfactory to Bank, that Parent has complied with its obligations set forth in Section 3.2(k).

 

3.3          Security
Documents. Guarantor will perform, observe and comply with all of the terms and conditions of the Security Documents.

 

4.          EXPENSES.
Guarantor will pay all of the costs, expenses and fees, including, without limitation, all reasonable attorneys’ fees, incurred
by Bank in enforcing or attempting to enforce this Guaranty, whether the same is enforced by suit or otherwise, and all amounts
recoverable by law, including, without limitation, interest on any unpaid amounts due under this Guaranty.

(ii)         Each

5.2          Payment

on maturity, after the acceleration of any of the Guaranteed Obligations, on the occurrence of an Event of Default, on the occurrence

dollars the total amount of the Guaranteed Obligations due and payable (whether due and payable as a result of maturity, acceleration,
or otherwise), and (ii) Bank will have the right: (a) to proceed directly against Guarantor under this Guaranty without first exhausting
any other remedy it may have and without resorting to any security or guaranty held by Bank, (b) to compromise, settle, release,
discharge or terminate any of the obligations of any other obligor(s) or guarantor(s) of the Guaranteed Obligations as Bank, in
its discretion, determines without thereby in any way affecting, limiting or diminishing its rights thereafter to enforce the obligations

other security given to Bank with respect to the Guaranteed Obligations in satisfaction of the Guaranteed Obligations in such order

other powers, rights and remedies under this Guaranty, the Security Documents, the other Loan Documents and under applicable law.

    	-13-

    	 

    

 

5.3          Subordination.
Until the Guaranteed Obligations have been fully paid, performed and satisfied: (i) any and all claims of Guarantor against Borrowers
(or any one of them), any indorser or any other obligor or guarantor of all or any part of the Guaranteed Obligations, or against
any of their respective properties are, by the signing of this Guaranty by Guarantor, made subordinate and subject in right of
payment and performance to the prior payment and performance to Bank in full of all of the Guaranteed Obligations; and (ii) Guarantor
will not exercise any right to enforce any remedy which Guarantor now has or may in the future have against any Borrower, any indorser
or any other obligor or guarantor of all or any part of the Guaranteed Obligations.

 

5.4          Maximum
Liability. The provisions of this Guaranty are severable, and in any action or proceeding involving any state corporate law,
or any state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally,
if the obligations of Guarantor under this Guaranty would otherwise be held or determined to be avoidable, invalid or unenforceable
on account of the amount of Guarantor’s liability under this Guaranty, then, notwithstanding any other provision of this
Guaranty to the contrary, the amount of such liability shall, without any further action by Guarantor or Bank, be automatically
limited and reduced to the highest amount that is valid and enforceable as determined in such action or proceeding (such highest
amount determined hereunder being Guarantor’s “Maximum Liability”). This Section with respect to the Maximum
Liability of Guarantor is intended solely to preserve the rights of Bank to the maximum extent not subject to avoidance under applicable
law, and neither Guarantor nor any other Person or entity shall have any right or claim under this Section with respect to such
Maximum Liability, except to the extent necessary so that the obligations of Guarantor hereunder shall not be rendered voidable
under applicable law. Guarantor agrees that the Guaranteed Obligations may at any time and from time to time exceed the Maximum
Liability of Guarantor without impairing this Guaranty or affecting the rights and remedies of Bank hereunder; provided
that, nothing in this sentence shall be construed to increase Guarantor’s obligations hereunder beyond its Maximum Liability.

 

6.          GENERAL.

 

6.1          Cumulative
Remedies. The remedies provided in this Guaranty, the Financing Agreement, and the other Loan Documents are cumulative and
not exclusive of any remedies provided by law. Exercise of one or more remedy(ies) by Bank does not require that all or any other
remedy(ies) be exercised and does not preclude later exercise of the same remedy. If there is any conflict, ambiguity, or inconsistency,
in Bank’s judgment, between the terms of this Guaranty and any of the Financing Agreement or other Loan Documents, then the
applicable terms and provisions, in Bank’s judgment, providing Bank with the greater rights, remedies, powers, privileges,
or benefits will control.

 

    	-14-

    	 

    

 

6.2          Waivers
and Amendments in Writing. Failure by Bank to exercise any right, remedy or option under this Guaranty, the Financing Agreement
or in any other Loan Document or delay by Bank in exercising the same shall not operate as a waiver by Bank of its right to exercise
any such right, remedy or option. No waiver by Bank shall be effective unless it is in writing and then only to the extent specifically
stated. This Guaranty cannot be amended, modified, changed or terminated orally.

 

6.3          Entire
Agreement; Counterparts; Fax Signatures. This Guaranty and the other Loan Documents to which Guarantor is a party constitute
the entire agreement between the parties with respect to the subject matter of this Guaranty, and supersede all prior written and
oral agreements and understandings. Any request from time to time by Guarantor for Bank’s consent under any provision in
this Guaranty must be in writing, and any consent to be provided by Bank under this Guaranty from time to time must be in writing
in order to be binding on Bank; however, Bank will have no obligation to provide any consent requested by Guarantor, and
Bank may, for any reason in its discretion exercised in good faith, elect to withhold the requested consent. Two or more duplicate
originals of this Guaranty may be signed by the parties, each of which shall be an original but all of which together shall constitute
one and the same instrument. Any documents delivered by, or on behalf of, Guarantor by facsimile transmission or other electronic
delivery of an image file reflecting the execution hereof: (i) may be relied on by each party as if the document were a manually
signed original and (ii) will be binding on each party for all purposes of the Financing Agreement and other Loan Documents.

 

6.4          Headings;
Construction. Section headings in this Guaranty are included for convenience of reference only and shall not relate to the
interpretation or construction of this Guaranty. Any and all references in this Guaranty to any other document or documents will
be references to that other document or documents as they may, from time to time, be modified, amended, renewed, consolidated,
extended or replaced.

 

6.5          Separate
Instrument. This Guaranty constitutes a separate instrument, enforceable in accordance with its terms, and neither this Guaranty
nor the obligations of Guarantor under this Guaranty will, under any circumstance or in any legal proceeding, be deemed to have
merged into any other agreement or obligation of Guarantor.

 

6.6          Severability.
If any term of this Guaranty is found invalid under Ohio law or laws of mandatory application by a court of competent jurisdiction,
that invalid term will be considered excluded from this Guaranty and will not invalidate the remaining terms of this Guaranty.

 

6.7          OHIO
LAW. THIS GUARANTY HAS BEEN DELIVERED AT AND ACCEPTED AT AND SHALL BE DEEMED TO HAVE BEEN MADE IN HAMILTON COUNTY, OHIO. THIS
GUARANTY SHALL BE DEEMED TO BE A CONTRACT MADE UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF OHIO (WITHOUT REFERENCE
TO OHIO CONFLICTS OF LAW PRINCIPLES).

GUARANTY, ITS VALIDITY OR PERFORMANCE, AND WITHOUT LIMITATION ON THE ABILITY OF BANK, ITS SUCCESSORS AND ASSIGNS, TO EXERCISE ALL
RIGHTS AS TO THE LOAN COLLATERAL AND TO INITIATE AND PROSECUTE IN ANY APPLICABLE JURISDICTION ACTIONS RELATED TO REPAYMENT OF THE
GUARANTEED OBLIGATIONS, SHALL BE INITIATED AND PROSECUTED AS TO ALL PARTIES AND THEIR SUCCESSORS AND ASSIGNS AT CINCINNATI, OHIO.

GUARANTOR AND BANK AT THEIR RESPECTIVE ADDRESSES SET FORTH IN THIS GUARANTY OR AS OTHERWISE PROVIDED UNDER THE LAWS OF THE STATE
OF CINCINNATI, OHIO. GUARANTOR WAIVES ANY OBJECTION BASED ON FORUM NON CONVENIENS, AND ANY OBJECTION TO VENUE OF ANY ACTION
INSTITUTED HEREUNDER, AND CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY THE COURT.

 

6.9          Successors
and Assigns. This Guaranty will inure to the benefit of Bank, its successors and assigns and be binding on the successors and
assigns of Guarantor.

 

6.10        Notices.
Any notice required, permitted or contemplated hereunder shall, except as expressly provided in this Guaranty, be in writing and
addressed to the party to be notified at the address set forth below or at such other address as each party may designate for itself
from time to time by notice hereunder, and shall be deemed validly given: (i) three days following deposit in the U.S. certified
mails (return receipt requested), with proper postage prepaid, or (ii) the next Business Day after such notice was delivered to
a regularly scheduled overnight delivery carrier with delivery fees either prepaid or an arrangement satisfactory with such carrier
made for the payment thereof, or (iii) upon receipt of notice given by telecopy (fax), mailgram, telegram, telex or personal delivery:

6.11        Separate

cause of action under this Guaranty, and separate suits, at Bank’s sole option, may be brought under this Guaranty as each
cause of action arises.

6.12        Survival

6.13        Equitable
Relief. Guarantor recognizes that, in the event that Guarantor fails to perform, observe or discharge any of its obligations
or liabilities under this Guaranty, any remedy at law may prove to be inadequate relief to Bank; therefore, Guarantor agrees
that Bank, if Bank so requests, shall be entitled to temporary and permanent injunctive relief in any such case without the necessity
of proving actual damages.

 

6.14        WAIVER

may incur arising out of this Guaranty or any act taken by Bank hereunder (including any arising out of the comparative, contributory
or sole negligence of any of Bank or any such indemnified party) except to the extent of the willful misconduct or gross negligence
of such indemnified party, as determined by a court of competent jurisdiction in a final non-appealable judgment or order. The

execution or delivery of this Agreement or any other document to be furnished hereunder or in connection herewith; and

5.          DEBTOR’S
RESPONSIBILITIES:

(i)          execute
and deliver such supplemental instruments, in the form of assignments or otherwise, as Secured Party shall reasonably require for
the purpose of confirming and perfecting Secured Party’s security interest in any or all of the Pledged Collateral, or as
is necessary to provide Secured Party with control (within the meaning of the Uniform Commercial Code) over the Pledged Collateral
or any portion thereof in order for Secured Party to perfect its security interest;

 

    	- 3 -

    	 

    

 

(ii)         at
its expense and upon the reasonable request of Secured Party, make available to Secured Party, at reasonable times and upon reasonable
notice, any and all of Debtor’s books, records, written memoranda, correspondence, and other instruments or writings that
evidence or relate to the Pledged Collateral;

 

(iii)        notify
Secured Party promptly in writing of any information which Debtor has or may receive which could reasonably be expected to materially
and adversely affect the value of the Pledged Collateral or the rights of Secured Party with respect thereto;

 

(iv)        not
change its state of incorporation or form of organization without the prior consent of Secured Party;

 

(v)         pay
all costs of filing any financing, continuation or termination statements with respect to the Lien created hereby;

 

(vi)        pay
all reasonable expenses, including reasonable attorneys’ fees, of Secured Party incurred by Secured Party in the exercise
(including enforcement) of any of Secured Party’s rights or remedies under this Agreement or applicable law; and Debtor agrees
that said expenses and fees shall constitute part of the Obligations and be secured by the Pledged Collateral; and

 

(vii) except to the
extent expressly permitted by the other Loan Documents, not consent (without the prior consent of Secured Party) to (A) any amendment
or modification of any charter documents or shareholder agreement of EQMI, or (B) the dissolution, termination or liquidation,
of EQMI.

 

(b)          To
protect, perfect, or enforce, from time to time, Secured Party’s rights or interests in the Pledged Collateral, Secured Party
may, in its discretion (but without any obligation to do so): (i) discharge any Liens at any time levied or placed on the Pledged
Collateral (other than Permitted Liens unless an Event of Default has occurred and is continuing), and (ii) obtain any record from
any service bureau and pay such service bureau the cost thereof. All costs and expenses incurred by Secured Party in exercising
its discretion under this subparagraph (b) will be part of the Obligations secured by the Pledged Collateral.

 

(c)          Debtor
will cause EQMI to register the pledge of the Pledged Interests in favor of Secured Party, as registered pledgee, on the books
and records of EQMI.

 

(d)          Debtor
will cause EQMI not to issue any shares or other Ownership Interests in addition to, or in exchange or substitution for, the Pledged
Interests to the extent such additional issuance, exchange or substitution would result in an Event of Default, unless such issuance,
exchange or substitution is with the prior consent of Secured Party.

6.          POWER
OF ATTORNEY: Debtor hereby makes, constitutes and appoints Secured Party its true and lawful attorney in fact to act with respect
to the Pledged Collateral in any transaction, legal proceeding, or other matter in which Secured Party is acting pursuant to this
Agreement. Debtor: (i) specifically authorizes Secured Party as its true and lawful attorney in fact to execute and/or authenticate
on its behalf and/or file financing statements reflecting Secured Party’s security interest in the Pledged Collateral and
any other documents to perfect or otherwise further the security interest granted herein; (ii) specifically authorizes Secured
Party to act as its true and lawful attorney in fact to execute and/or authenticate any third party agreements or assignments to
grant Secured Party control (within the meaning of the Uniform Commercial Code) over the Pledged Collateral to perfect its interest
therein, including third party agreements between Debtor, Secured Party and, securities intermediaries, which third party agreements
direct the third party to accept orders and instructions from Secured Party regarding the maintenance and disposition of the Pledged
Collateral and the products and proceeds thereof; (iii) specifically authorizes Secured Party, upon the occurrence and during the
continuance of an Event of Default, to issue, without further consent of Debtor, all (a) instructions to any bank at which any
deposit account is maintained with respect to all existing or future funds held in such deposit account constituting part of the
Pledged Collateral and (b) exclusive entitlement orders to all securities intermediaries with respect to all existing or future
investment property, constituting part of the Pledged Collateral, held in any securities account maintained by such securities
intermediary; and (iv) specifically authorizes Secured Party, upon the occurrence and during the continuance of an Event of Default,
to receive, indorse and collect all instruments made payable to Debtor representing any dividend, interest payment or other distribution
in respect of the Pledged Collateral or any part thereof and to give full discharge for the same.

 

7.          VOTING
RIGHTS; DEFAULT:

 

7.1           Voting
Rights; Distributions.

 

7.1.1           Absent
an Event of Default. So long as no Event of Default occurs and is continuing: (i) Debtor shall be entitled to exercise any
and all voting and other consensual rights pertaining to the Pledged Interests or any part thereof for any purpose not inconsistent
with the terms of this Agreement, the Financing Agreement or the other Loan Documents; and (ii) Debtor shall be entitled, subject
to the terms of the Financing Agreement, to receive and retain any and all distributions and interest paid in respect of the Pledged
Interests; provided that (a) Debtor acknowledges that there are no permitted distributions from EQMI under the Financing
Agreement other than as expressly provided in Section 10.18 thereof and (b) any and all: (1) distributions and interest
paid or payable (other than in cash) in respect of, and instruments and other property received, receivable or otherwise distributed
in respect of, or in exchange for, any Pledged Interests; and (2) cash paid, payable or otherwise distributed in respect of principal
of, or in redemption of, or in exchange for, any Pledged Interests shall be delivered to Secured Party, or such nominee(s) of Secured
Party as Secured Party shall direct, to hold as Pledged Collateral and shall, if received by Debtor, be received in trust for the
benefit of Secured Party, be segregated from the other property or funds of Debtor, and be forthwith delivered to Secured Party,
or such nominee(s) of Secured Party as Secured Party shall direct, as Pledged Collateral in the same form as so received (with
any necessary indorsement(s)). Debtor shall, upon request by Secured Party, promptly execute such instruments, documents and agreements
and do such acts as may be necessary or advisable to give effect to the provisions of this Section 7.1.1.

 

    	- 5 -

    	 

    

 

7.1.2           Upon
an Event of Default. Upon the occurrence and during the continuance of an Event of Default: (i) all rights of Debtor to exercise
the voting and other consensual rights which it would otherwise be entitled to exercise pursuant to Section 7.1.1 and to
receive the distributions and interest payments which it would otherwise be authorized to receive and retain pursuant to Section
7.1.1 shall cease, at Secured Party’s election, and all such rights shall thereupon become vested in Secured Party, or
such nominee(s) of Secured Party as Secured Party shall direct, who shall thereupon have the sole right to exercise such voting
and other consensual rights and to receive and hold as Pledged Collateral such distributions and interest payments; and (ii) all
distributions and interest payments which are received by Debtor contrary to the provisions of Section 7.1 shall be received
in trust for the benefit of Secured Party, shall be segregated from other funds of Debtor, and shall be forthwith paid over to
Secured Party, or such nominee(s) of Secured Party as Secured Party shall direct as Pledged Collateral in the same form as so received
(with any necessary indorsement(s)).

 

7.2           Default.

 

7.2.1           Generally.
If an Event of Default occurs and is continuing, then, in any such event and without limitation of Secured Party’s rights
and remedies in Section 7.1, Secured Party may, without further notice to Debtor except as expressly provided in the other
Loan Documents, resort to the rights and remedies available at law, in equity and under this Agreement and the other Loan Documents,
including the rights and remedies of a Secured Party under the Uniform Commercial Code. No remedy set forth herein is exclusive
of any other available remedy or remedies, but each is cumulative and in addition to every other remedy given under this Agreement,
the other Loan Documents or now or hereafter existing at law or in equity or by statute. Secured Party may proceed to protect and
enforce its rights by an action at law, in equity or by any other appropriate proceedings. No failure on the part of Secured Party
to enforce any of the rights hereunder shall be deemed a waiver of such rights or of any Event of Default, and no waiver of any
Event of Default will be deemed to be a waiver of any subsequent Event of Default.  Moreover, Debtor acknowledges and agrees
that Secured Party shall have no obligation to, and Debtor hereby waives to the fullest extent permitted by law any right that
it may have to require Secured Party to: (a) prepare any of the Pledged Collateral for sale, (b) pursue any Person to collect any
of the Obligations, or (c) exercise collection remedies against any Persons obligated on the Pledged Collateral. Secured Party’s
compliance with applicable local, state or federal law requirements, in addition to those imposed by the Uniform Commercial Code,
in connection with a disposition of any or all of the Pledged Collateral will not be considered to adversely affect the commercial
reasonableness of any disposition of any or all of the Pledged Collateral under the Uniform Commercial Code.

 

    	- 6 -

    	 

    

 

7.2.2           Pledged
Interests. Without limiting any other rights or remedies available to Secured Party under Section 7.2.1, at any time
after an Event of Default occurs and is continuing, Secured Party, at its option and without any obligation to do so, may transfer
to or register in its name, or the name of any nominee(s), all or any part of the Pledged Interests, and Secured Party may exercise
in respect of the Pledged Interests, in addition to other rights and remedies provided for herein or otherwise available to it,
all the rights and remedies under applicable law and of a secured party on default under the Uniform Commercial Code; and Secured
Party may also, with ten (10) days prior notice to Debtor, sell the Pledged Interests or any part thereof in one or more parcels
at public or private sale, at any exchange, broker’s board or any of Secured Party’s offices or elsewhere, for cash,
on credit or for future delivery, and upon such other terms as Secured Party may deem commercially reasonable. Secured Party shall
be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers to Persons
who will represent and agree that they are purchasing the Pledged Interests for their own account in compliance with Regulation
D of the Securities Act of 1933, as amended, and applicable state securities laws or under any other applicable exemption available
under such laws. Debtor agrees that at least ten (10) days notice to Debtor of the time and place of any public sale or the time
after which any private sale is to be made shall constitute reasonable notification. Secured Party shall not be obligated to make
any sale of the Pledged Interests regardless of notice of sale having been given. Secured Party may adjourn any public or private
sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made
at the time and place it was so adjourned. Any cash held by Secured Party as Pledged Interests and all cash proceeds received by
Secured Party in respect of any sale of, collection from, or other realization upon all or any part of the Pledged Interests may,
in the sole discretion of Secured Party, be held by Secured Party as Pledged Collateral for, and/or then or at any time thereafter
in whole or in part by Secured Party against, all or any parts of the Obligations in such order as Secured Party shall elect in
its discretion exercised in good faith. Any surplus of such cash or cash proceeds held by Secured Party and remaining after payment
in full of all of the Obligations shall be paid over to Debtor or to whomsoever may be lawfully entitled to receive such surplus.
Without precluding any other methods of sale, the sale of the Pledged Interests, or any part thereof, shall have been made in a
commercially reasonable manner if conducted in conformity with reasonable commercial practices of banks or finance companies disposing
of similar property, but in any event, Secured Party may sell or otherwise dispose of the Pledged Interests without assuming any
credit risk. Debtor recognizes that federal, state and/or foreign securities and other laws may limit the flexibility desired to
achieve an otherwise commercially reasonable disposition of the Pledged Interests, and in the event of potential conflict between
such laws or regulations and what in other circumstances might constitute commercial reasonableness, it is intended that consideration
for such laws and regulations will prevail over attempts to achieve such commercial reasonableness. In connection with any sale
or other disposition of the Pledged Interests, compliance by Secured Party with the written advice of its counsel concerning the
potential effect of any such law or regulation shall not be cause for Debtor, or any other Person, to claim that such sale or other
disposition was not commercially reasonable, it being the intent of Debtor that Secured Party not be obligated to risk contravening
any such law or regulation in order to effect what, but for such law or regulation, would be a commercially reasonable disposition.
By way of example and not by way of limitation, with respect to any sale or other disposition of the Pledged Interests or any portion
thereof: (i) such sale or disposition shall be commercially reasonable if made by and through a licensed broker/dealer acting under
instructions to obtain in its judgment the best disposition price known to it on the market (however, this provision does not suggest
that such disposition is either preferable or exclusive); (ii) such sale or disposition shall be deemed to have been at a public
sale if, in connection with such sale or disposition, Secured Party obtains bids from at least two qualified purchasers; and (iii)
the net book value reflected on EQMI’s most recent financial statements, adjusted to the date of any such sale or other disposition,
is deemed to be a commercially reasonable price (but a price less than such net book value is not, of itself, deemed to be commercially
unreasonable). To the extent permitted by applicable law, and except as otherwise expressly provided under this Agreement or otherwise,
Debtor hereby waives all rights now or hereafter conferred by statute or otherwise which may require Secured Party to give any
notice, make any demand, or invoke any legal process with respect to the sale or other disposition of the Pledged Interests or
which may require Secured Party to sell or otherwise dispose of the Pledged Interests in mitigation of Secured Party’s damages
or which may otherwise limit or modify any of Secured Party’s remedies or rights under this Agreement. Secured Party shall
be under no duty to sell or otherwise realize upon the Pledged Interests. At any time, Secured Party may release or surrender all
or any part of the Pledged Interests to Debtor.

 

    	- 7 -

    	 

    

 

8.          WAIVERS:
Debtor acknowledges and agrees that Debtor, by signing this Agreement, is subjecting the Pledged Collateral to the Lien of Secured
Party for the payment and performance of all Obligations. Debtor waives: (a) any demand, protest or notice of any action taken
by Secured Party (except those required by this Agreement or the other Loan Documents, as applicable) under this Agreement, the
other Loan Documents, or in connection with any of the Obligations; (b) any and all rights under any theory of marshaling or ordering
of disposition of collateral; (c) any claim that Debtor’s obligations under this Agreement or that the Obligations are released,
discharged, affected, modified or impaired by any event except payment in full and satisfaction of the Obligations, including any
of the following events: (i) any indulgence of Secured Party or substitution for, exchange, or loss, or release of, all or any
portion of the Loan Collateral, (ii) the extension of the time for payment of any of the Obligations or the waiver, modification
or amendment (whether material or otherwise) of any Obligation under the Financing Agreement or any of the other Loan Documents
or the acceptance of partial payments of the Obligations, (iii) the compromise, settlement, release, discharge or termination of
any or all of the obligations of Debtor to Secured Party by operation of law or otherwise except as may result from the full and
prompt performance and payment of the Obligations, or (iv) any other defenses; and (d) any claim or other right which Debtor may
now have or hereafter acquire against any other Person that is primarily or contingently liable on the Obligations which arises
from the existence or performance of Debtor’s obligations under this Agreement, including any right of subrogation, reimbursement,
exoneration, contribution, indemnification, any right to participate in any claim or remedy of Secured Party against Debtor or
any collateral as security therefor, which Secured Party now has or hereafter acquires, whether or not such claim, remedy or right
arises in equity, or under contract, statute or common law, until such time as the Obligations and all obligations of Debtor hereunder
have been fully paid and satisfied. Debtor shall not assert any claim against Secured Party on any theory of liability for consequential,
special, indirect or punitive damages.

 

9.          GENERAL
PROVISIONS:

 

(a)          All
rights of Secured Party shall inure to the benefit of its successors, assigns and affiliates and all obligations of Debtor shall
bind the successors and assigns of Debtor.

 

(b)          This
Agreement and the other Loan Documents, as applicable, contain the entire agreement of the parties with respect to the subject
matter of this Agreement, and no oral agreement whatsoever, whether made contemporaneously herewith or hereafter shall amend, modify
or otherwise affect the terms of this Agreement. Any notice required, permitted or contemplated hereunder shall, except as expressly
provided in this Agreement, be given in accordance with the Guaranty. This Agreement may be signed
by facsimile signatures or other electronic delivery of an image file reflecting the execution hereof, and, if so signed: (i) may
be relied on by each party as if the document were a manually signed original and (ii) will be binding on each party for all purposes.

 

    	- 8 -

    	 

    

 

(c)          All
rights and liabilities hereunder shall be governed and limited by and construed in accordance with the local laws of the State
of Ohio (without regard to Ohio conflicts of law principles).

 

(d)          If
any provision of this Agreement is found invalid by a court of competent jurisdiction, the invalid term will be considered excluded
from this Agreement and will not invalidate the remaining provisions of this Agreement.

 

(e)          Debtor
hereby irrevocably authorizes Secured Party at any time and from time to time to file in any filing office in any jurisdiction
any initial financing statements and amendments thereto including financing statements that: (i) indicate the Pledged Collateral
as being of an equal or lesser scope or with greater detail and (ii) provide any other information required by Part 5 of Article
9 of the Uniform Commercial Code for the sufficiency or filing office acceptance of any financing statement or amendment. Debtor
hereby irrevocably authorizes Secured Party at any time and from time to time to correct or complete, or to cause to be corrected
or completed, any financing statements, continuation statements or other such documents as have been filed naming Debtor as debtor
and Secured Party as secured party. Secured Party is hereby authorized to give notice to any creditor, landlord or any other Person
as may be necessary or desirable under applicable laws to evidence, protect, perfect, or enforce the security interest granted
to Secured Party in the Pledged Collateral.

 

(f)          Secured
Party shall have no duty of care with respect to the Pledged Collateral except that Secured Party shall exercise reasonable care
with respect to the Pledged Collateral in Secured Party’s custody. Secured Party shall be deemed to have exercised reasonable
care if: (A) such property is accorded treatment substantially equal to that which Secured Party accords its own property that
is similar to the Pledged Collateral or (B) Secured Party takes such action with respect to the Pledged Collateral as Debtor shall
reasonably request in writing. Secured Party will not be deemed to have, and nothing in this subparagraph (f) may be construed
to deem that Secured Party has, failed to exercise reasonable care in the custody or preservation of Pledged Collateral in its
possession merely because either: (1) Secured Party failed to comply with any request of Debtor or (2) Secured Party failed to
take steps to preserve rights against any Persons in such property. Debtor agrees that Secured Party has no obligation to take
steps to preserve rights against any prior parties.

 

(g)          Any
capitalized term used but not defined herein shall have the meaning ascribed thereto in the Guaranty. The definition of any document,
instrument or agreement includes all schedules, attachments and exhibits thereto and all renewals, extensions, supplements, restatements
and amendments thereof. All exhibits and schedules attached to this Agreement are incorporated into, made and form an integral
part of, this Agreement for all purposes. As used in this Agreement, “hereunder,” “herein,” “hereto,”
“this Agreement” and words of similar import refer to this entire document; “including” is used by way
of illustration and not by way of limitation, unless the context clearly indicates the contrary; the singular includes the plural
and conversely; and any action required to be taken by Debtor is to be taken promptly, unless the context clearly indicates the
contrary.

(h)          SECURED
PARTY AND DEBTOR HEREBY WAIVE THE RIGHT TO TRIAL BY JURY OF ANY MATTERS ARISING OUT OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY.         

 

(i) This Agreement will terminate
(“Termination”) on the later to occur of: (i) the full performance, payment and satisfaction of the Obligations
or (ii) the termination of the Guaranty. Upon such Termination, Secured Party will, upon Debtor’s request, execute and deliver
to Debtor any release of its Lien on the Pledged Collateral or similar instrument of re-conveyance and deliver UCC termination
statements with respect to its Lien on the Pledged Collateral.
