d.      From
and after the date hereof (the “Effective Date”), New Borrower, Borrower, and Bank desire to supplement the
terms and provisions of the Original Loan Agreement as provided herein, and the Original Loan Agreement as supplemented by this
Joinder, and as may be hereafter further supplemented, amended, modified or restated from time to time, shall be referred to collectively
as the “Loan Agreement.”


 


e.      The
Bank desires that New Borrower execute this Joinder for the purpose of acknowledging that it is and shall be a Borrower under the
Loan Agreement and the other Loan Documents.


 


f.       New
Borrower has read and approved the Loan Documents and has asked Bank to agree to allow New Borrower to become a party to the Loan
Documents in order to facilitate its ability to continue to operate its business by achieving a stronger financial base for itself
and its affiliated companies.


 


NOW, THEREFORE,
in consideration of the premises herein contained, and for other good and valuable consideration (the receipt, sufficiency and
adequacy of which are hereby acknowledged), the parties hereto (intending to be legally bound) hereby agree as follows:


 


1.       Incorporation.
The foregoing preamble and recitals are incorporated herein by this reference.


 






    


     


    

 


2.       Joinder
and Assumption. From and after the Effective Date, New Borrower hereby absolutely and unconditionally:


 


(a) (i) joins as and
becomes a party to the Loan Agreement as a Borrower thereunder, (ii) assumes, as a joint and several obligor thereunder, all of
the obligations, liabilities and indemnities of a Borrower under the Loan Agreement and all other Loan Documents, and (iii) covenants
and agrees to be bound by and adhere to all of the terms, covenants, waivers, releases, agreements and conditions of or respecting
a Borrower with respect to the Loan Agreement and the other Loan Documents and all of the representations and warranties contained
in the Loan Agreement (in the manner set forth in Section 5 of this Joinder) and the other Loan Documents with respect to New Borrower;
and


 


(b)       hereby
grants and pledges to the Bank, a continuing security interest in all of such New Borrower’s now owned and existing and hereafter
acquired and arising Collateral, as collateral security for the prompt and complete payment and performance when due (whether at
the stated maturity, by acceleration or otherwise) of all Obligations. New Borrower hereby authorizes the Bank to file at any time
uniform commercial code financing statements in such jurisdictions and offices as the Bank deems necessary in connection with the
perfection of a security interest in all of such New Borrower’s now owned or hereafter arising or acquired assets and property,
including, without limitation, accounts receivable, deposit accounts, equipment, general intangibles, inventory, and any and all
other personal property of such New Borrower, and all products, substitutions, replacements, and proceeds of such property and
assets. New Borrower has read the Loan Agreement and affirmatively grants to Bank all rights to New Borrower’s assets as
set forth in said Loan Agreement and the Loan Documents.


 


From and after the
Effective Date, any reference to the term “Borrower” in the Loan Agreement shall also include New Borrower. Except
as expressly provided herein, the Loan Agreement remains in full force and effect and is hereby ratified and confirmed in all respects.


 


3.      Amendments
on the Effective Date. Effective as of the Effective Date, the Loan Agreement is hereby amended as follows:


 


(a) A new Section 4.3
is hereby added to the Loan Agreement, as follows:


 


4.3       Pledge
of Collateral. Borrower hereby pledges, assigns and grants to Bank a security interest in all the Shares, together with
all proceeds and substitutions thereof, all cash, stock and other moneys and property paid thereon, all rights to subscribe
for securities declared or granted in connection therewith, and all other cash and noncash proceeds of the foregoing, as
security for the performance of the Obligations. Borrower will deliver to Bank (i) on the Closing Date, the certificate or
certificates for any then-certificated Shares, and (ii) with respect to any Shares uncertificated as of the Closing Date,
immediately upon certification, the certificate or certificates for the Shares, in each case accompanied by an instrument of
assignment duly governing the Shares. Borrower shall cause the books of each entity whose Shares are part of the Collateral
and any transfer agent to reflect the pledge of the Shares. Upon the occurrence and during the continuance of an Event of
Default hereunder, Bank may effect the transfer of any securities included in the Collateral (including but not limited to
the Shares) into the name of Bank and cause new certificates representing such securities to be issued in the name of Bank or
its transferee. Unless an Event of Default shall have occurred and be continuing, Borrower shall be entitled to exercise any
voting rights with respect to the Shares and to give consents, waivers and ratifications in respect thereof, provided that no
vote shall be cast or consent, waiver or ratification given or action taken which would be inconsistent with any of the terms
of this Agreement or which would constitute or create any violation of any of such terms. All such rights to vote and give
consents, waivers and ratifications shall terminate upon the occurrence and continuance of an Event of Default.


 






    2


     


    

 


(b) A new Section
5.14 is hereby added to the Loan Agreement, as follows:


 


5.14     Shares.
Borrower has full power and authority to create a first lien on the Shares, and no disability or contractual obligation exists
that would prohibit Borrower from pledging the Shares pursuant to this Agreement. To Borrower’s knowledge, there are no subscriptions,
warrants, rights of first refusal or other restrictions on transfer relative to, or options exercisable with respect to the Shares.
The Shares have been and will remain duly authorized and validly issued, and are fully paid and non-assessable. To Borrower’s
knowledge, the Shares are not the subject of any present or threatened suit, action, arbitration, administrative or other proceeding,
and Borrower knows of no reasonable grounds for the institution of any such proceedings. No interest in any limited liability company
or limited partnership controlled by Borrower is represented by a certificate unless (a) the limited liability company agreement
or limited partnership agreement expressly provides that such interest shall be a “Security” within the meaning of
Article 8 of the Code, and (b) such certificate has been delivered to Bank. With respect to each limited liability company or limited
partnership controlled by Borrower whose interests are uncertificated, such limited liability company or limited partnership has
not elected, whether in its limited liability company agreement or limited partnership agreement or otherwise, to have such interests
be treated as a “Security” within the meaning of Article 8 of the Code.


 


(c) A new Article
13 is hereby added to the Loan Agreement, as follows:


 


13.      
 CO-BORROWER PROVISIONS.


 


13.1     Primary
Obligation. This Agreement is a primary and original obligation of each Borrower and shall remain in effect notwithstanding
future changes in conditions, including any change of law or any invalidity or irregularity in the creation or acquisition of any
Obligations or in the execution or delivery of any agreement between Bank and any Borrower. Each Borrower shall be liable for existing
and future Obligations as fully as if all of all Credit Extensions were advanced to such Borrower. Bank may rely on any certificate
or representation made by any Borrower as made on behalf of, and binding on, all Borrowers, including without limitation Disbursement
Request Forms, Borrowing Base Certificates and Compliance Certificates.


 


13.2     Enforcement
of Rights. Borrowers are jointly and severally liable for the Obligations and Bank may proceed against one or more of the Borrowers
to enforce the Obligations without waiving its right to proceed against any of the other Borrowers.


 


13.3     Borrowers
as Agents. Each Borrower appoints the other Borrower as its agent with all necessary power and authority to give and receive
notices, certificates or demands for and on behalf of both Borrowers, to act as disbursing agent for receipt of any Credit Extensions
on behalf of each Borrower and to apply to Bank on behalf of each Borrower for Credit Extensions, any waivers and any consents.
This authorization cannot be revoked, and Bank need not inquire as to each Borrower’s authority to act for or on behalf of
Borrower.


 






    3


     


    

 


13.4    Subrogation and Similar Rights. Notwithstanding any other provision of this Agreement or any other Loan Document, each
Borrower irrevocably waives all rights that it may have at law or in equity (including, without limitation, any law subrogating
the Borrower to the rights of Bank under the Loan Documents) to seek contribution, indemnification, or any other form of reimbursement
from any other Borrower, or any other Person now or hereafter primarily or secondarily liable for any of the Obligations, for any
payment made by the Borrower with respect to the Obligations in connection with the Loan Documents or otherwise and all rights
that it might have to benefit from, or to participate in, any security for the Obligations as a result of any payment made by the
Borrower with respect to the Obligations in connection with the Loan Documents or otherwise. Any agreement providing for indemnification,
reimbursement or any other arrangement prohibited under this Section 13.4 shall be null and void. If any payment is made to a Borrower
in contravention of this Section 13.4, such Borrower shall hold such payment in trust for Bank and such payment shall be promptly
delivered to Bank for application to the Obligations, whether matured or unmatured.


 


13.5   
Waivers of Notice. Except as otherwise provided in this Agreement, each Borrower waives notice of acceptance hereof;
notice of the existence, creation or acquisition of any of the Obligations; notice of an Event of Default; notice of the amount
of the Obligations outstanding at any time; notice of intent to accelerate; notice of acceleration; notice of any adverse change
in the financial condition of any other Borrower or of any other fact that might increase the Borrower’s risk; presentment
for payment; demand; protest and notice thereof as to any instrument; default; and all other notices and demands to which the Borrower
would otherwise be entitled. Each Borrower waives any defense arising from any defense of any other Borrower, or by reason of the
cessation from any cause whatsoever of the liability of any other Borrower. Bank’s failure at any time to require strict
performance by any Borrower of any provision of the Loan Documents shall not waive, alter or diminish any right of Bank thereafter
to demand strict compliance and performance therewith. Nothing contained herein shall prevent Bank from foreclosing on the Lien
of any deed of trust, mortgage or other security instrument, or exercising any rights available thereunder, and the exercise of
any such rights shall not constitute a legal or equitable discharge of any Borrower. Each Borrower also waives any defense arising
from any act or omission of Bank that changes the scope of the Borrower’s risks hereunder.


 


13.6   
Subrogation Defenses. Each Borrower hereby waives any defense based on impairment or destruction of its subrogation
or other rights against any other Borrower and waives all benefits which might otherwise be available to it under any statutory
or common law suretyship defenses or marshalling rights, now or hereafter in effect.


 


13.7    
Right to Settle, Release.


 


(a)       
The liability of Borrowers hereunder shall not be diminished by (i) any agreement, understanding or representation that
any of the Obligations is or was to be guaranteed by another Person or secured by other property, or (ii) any release or unenforceability,
whether partial or total, of rights, if any, which Bank may now or hereafter have against any other Person, including another Borrower,
or property with respect to any of the Obligations.


 






    4


     


    

 


(b)      
 Without affecting the liability of any Borrower hereunder, Bank may (i) compromise, settle, renew, extend the time
for payment, change the manner or terms of payment, discharge the performance of, decline to enforce, or release all or any of
the Obligations with respect to a Borrower, (ii) grant other indulgences to a Borrower in respect of the Obligations, (iii) modify
in any manner any documents relating to the Obligations with respect to a Borrower, (iv) release, surrender or exchange any deposits
or other property securing the Obligations, whether pledged by a Borrower or any other Person, or (v) compromise, settle, renew,
or extend the time for payment, discharge the performance of, decline to enforce, or release all or any obligations of any guarantor,
endorser or other Person who is now or may hereafter be liable with respect to any of the Obligations.


 


13.8    
Subordination. All indebtedness of a Borrower now or hereafter arising held by another Borrower is subordinated to the
Obligations and the Borrower holding the indebtedness shall take all actions reasonably requested by Bank to effect, to enforce
and to give notice of such subordination.

any time, Borrower shall cease to own and control, of record and beneficially, directly or indirectly, one hundred percent (100%)

EXHIBIT B-1


 


COLLATERAL DESCRIPTION ATTACHMENT TO
AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT


 


All personal property of Borrower (herein referred to as “Borrower”
or “Debtor”) whether presently existing or hereafter created or acquired, and wherever located, including, but not
limited to:


 


(a)             
all accounts (including health-care-insurance receivables), chattel paper (including tangible and electronic chattel
paper), deposit accounts, documents (including negotiable documents), equipment (including all accessions and additions thereto),
financial assets, general intangibles (including patents, trademarks, copyrights, goodwill, payment intangibles, domain names and
software), goods (including fixtures), instruments (including promissory notes), inventory (including all goods held for sale or
lease or to be furnished under a contract of service, and including returns and repossessions), investment property (including
securities and securities entitlements), letter of credit rights, money, and all of Debtor’s books and records with respect
to any of the foregoing, and the computers and equipment containing said books and records;


 


(b)              
any and all cash proceeds and/or noncash proceeds of any of the foregoing, including, without limitation, insurance
proceeds, and all supporting obligations and the security therefor or for any right to payment. All terms above have the meanings
given to them in the North Carolina Uniform Commercial Code, as amended or supplemented from time to time, including revised Division
9 of the Uniform Commercial Code-Secured Transactions.


 


Notwithstanding the foregoing,
the Collateral shall not include any of the intellectual property, in any medium, of any kind or nature whatsoever, now or hereafter
owned or acquired or received by Borrower, or in which Borrower now holds or hereafter acquires or receives any right or interest
(collectively, the “Intellectual Property”); provided, however, that the Collateral shall include all accounts and
general intangibles that consist of rights to payment and proceeds from the sale, licensing or disposition of all or any part,
or rights in, the foregoing (the “Rights to Payment”).


 


Notwithstanding the foregoing,
if a judicial authority (including a U.S. Bankruptcy Court) holds that a security interest in the underlying Intellectual Property
is necessary to have a security interest in the Rights to Payment, then the Collateral shall automatically, and effective as of
