one and the same instrument.

 

12.         Entire
Agreement. This Amendment, together with the other Loan Documents, sets forth the entire agreement of the parties with
respect to the subject matter of this Amendment and supersedes all previous understandings, written or oral, in respect of this

(iii)        There
are no proceedings pending or, to the knowledge of Borrowers, threatened, against any Beacon Acquisition Party or any shareholder
of any Beacon Acquisition Party which call into question the validity or enforceability of any of the Beacon Acquisition Documents.

 

(iv)         Pursuant
to the Beacon Acquisition Documents, (a) Beacon Merger Sub will merge into, and be survived by EQMI, (b) Parent will become the
owner, free and clear of any Liens (except any Permitted Liens, as defined in the Parent Guaranty) of all of the Capital Stock
of EQMI, and (c) Argentum will become the owner, free and clear of any Liens of not less than 50% of the Capital Stock of Parent.
All consents and approvals of, and filings and permits with, and all other actions in respect of, all Governmental Authorities
required in order to consummate the Beacon Acquistion in accordance with the terms and conditions of the Beacon Acquisition Documents
and all applicable laws have been, or prior to the time required, will have been, obtained, given, filed, taken or waived, and
are in full force and effect. All applicable waiting periods with respect thereto have, or prior to the time when required, will
have, expired without, in all such cases, any action being taken by any competent authority which restrains, prevents or imposes
material adverse conditions upon the consummation of the Beacon Acquisition.

 

5.          Costs
and Expenses; Fee. As a condition of this Amendment, (a) Borrowers will pay to Bank a fee equal to $50,000.00, payable
in full on the Effective Date; such fee, when paid, will be fully earned and non-refundable under all circumstances, and (b) Borrowers
will promptly on demand pay or reimburse Bank for the costs and expenses incurred by Bank in connection with this Amendment, including,
without limitation, Attorneys’ Fees.

 

6.          Release.
Each Borrower hereby releases Bank from any and all liabilities, damages and claims arising from or in any way related to the
Obligations or the Loan Documents, other than such liabilities, damages and claims which arise after the execution of this Amendment.
The foregoing release does not release or discharge, or operate to waive performance by, Bank of its express agreements and obligations
stated in the Loan Documents on and after the date of this Amendment.

 

7.          Default.
Any default by Borrowers in the performance of Borrowers’ obligations under this Amendment shall constitute an Event of
Default under the Financing Agreement.

8.          Continuing
Effect of the Financing Agreement; Security. Except as expressly amended hereby, all of the provisions of the Financing
Agreement are ratified and confirmed and remain in full force and effect. Borrowers and Bank hereby expressly intend that this
Amendment shall not in any manner: (a) constitute the refinancing, refunding, payment or extinguishment of the Obligations evidenced
by the existing Loan Documents; (b) be deemed to evidence a novation of the outstanding balance of the Obligations; or (c) replace,
impair, or extinguish the creation, attachment, perfection or priority of the Liens on the Loan Collateral granted pursuant to
the Loan Documents. Each Borrower ratifies and reaffirms any and all grants of Liens to Bank on the Loan Collateral as security
for the Obligations, and each Borrower acknowledges and confirms that the grants of the Liens to Bank on the Loan Collateral:
(i) represent continuing Liens on all of the Loan Collateral, (ii) secure all of the Obligations, and (iii) represent valid, first
and best Liens on all of the Loan Collateral except to the extent, if any, of the Permitted Liens.

 

9.          One
Agreement; References; Fax Signature. The Financing Agreement, as amended by this Amendment, will be construed as one
agreement. All references in any of the Loan Documents to the Financing Agreement will be deemed to be references to the Financing
Agreement as amended by this Amendment. This Amendment may be signed by facsimile signatures or other electronic delivery of an
image file reflecting the execution thereof, and if so signed, (i) may be relied on by each party as if the documents were a manually
signed original and (ii) will be binding on each party for all purposes.

 

10.         Captions.
The headings to the Sections of this Amendment have been inserted for convenience of reference only and shall in no way modify
or restrict any provisions hereof or be used to construe any such provisions.

 

11.         Counterparts.
This Amendment may be executed in multiple counterparts, each of which shall be an original but all of which together shall constitute
one and the same instrument.

 

12.         Entire
Agreement. This Amendment, together with the other Loan Documents, sets forth the entire agreement of the parties with
respect to the subject matter of this Amendment and supersedes all previous understandings, written or oral, in respect of this
Amendment.

 

13.         Governing
Law. This Amendment shall be governed by and construed in accordance with the internal laws of the State of Ohio (without
regard to Ohio conflicts of law principles).

 

14.         Reaffirmation
of Cross-Guaranty. Each Borrower hereby: (i) ratifies and reaffirms the Cross-Guaranty and (ii) acknowledges and agrees
that no Borrower is released from its obligations under the Cross-Guaranty by reason of this Amendment or the other Loan Documents
and that the obligations of each Borrower under the Cross-Guaranty extend, among other Obligations of Borrowers to Lender, to
the Obligations of Borrowers under this Amendment and other Loan Documents.
