RECITALS

 

A.       Secured
Party has provided to the Parent a $650,000 loan (the “Loan”), evidenced by a 10% original issue discount secured
promissory note in $720,000 principal face amount due October 15, 2016 (the “Note”) and, unless otherwise expressly
defined in this Agreement, all capitalized terms when used herein, shall have the same meanings as they are defined in the Note;

 

B.       The
Subsidiary has agreed to provide the Secured Party with a full recourse guaranty for the prompt payment and performance of all
Obligations of the Parent, as set forth in the guaranty agreement annexed as Exhibit A to the Note (the “Guaranty Agreement”);

 

C.       The
Parties intend that the Debtor’s obligation to repay and otherwise perform its Obligations under the Note and the Note shall
be secured by all of the Collateral (as defined below) of the Debtor; and

 

D.       The
Recitals shall be deemed to be an integral part of this Agreement as though more fully set forth at length in the body of this
Agreement. Unless otherwise expressly defined in this Agreement, all capitalized terms used herein shall have the same meaning
as assigned to them in the Note.

 

NOW, THEREFORE, in
consideration of the above recitals and for other good and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the parties hereto agree as follows:

 

1.       Grant
of Security Interest. To secure the full and timely performance of all of Debtor’s obligations and liabilities to Secured
Party in connection with the Loan and pursuant to the Note and this Security Agreement (collectively, the “Obligations”),
each Debtor hereby unconditionally and irrevocably pledges, grants and hypothecates to Secured Party a continuing first priority
senior lien and security interest (the “Security Interest”) in and to all of the property described on Exhibit 1
to this Agreement (the “Collateral”).

 

    	 	 	 

     

    

 

2.           Priority of
Security Interest.           Secured Party and each Debtor each acknowledge and agree that:

 

(a)       subject
to the “Existing Liens” (as defined in Section 3(m) below) including any “Permitted Liens”
(as that term is defined on Exhibit 2 annexed hereto), the Security Interest granted by the Debtor in the Collateral pursuant
to this Agreement represents a perfected first priority senior secured lien, charge, encumbrance and Security Interest (collectively,
the “Lien”) in such Collateral; and

 

(b)       this
Security Interest shall include the terms and conditions of the Guaranty Agreement and the Secured Party’s right to receive
all required payments under the Note for so long as no Event of Default (as defined in the Note) shall have occurred and be continuing.

 

(c)       upon
the occurrence of any Event of Default under the Note or hereunder, the Secured Party may exercise any of its rights and remedies
with respect to the Collateral owned by the Debtor and the Security Interest granted by the Debtor hereunder, all as provided in
the Loan Documents

 

3.       Representations
and Covenants.

 

(a)       Other
Liens. Debtor owns all right, title and interest in the Collateral (or has appropriate rights to use in the case of property
subject to leases, licenses or similar arrangements in which any one or more Debtor is the licensee or lessee) and, except for
the Lien in favor of the Secured Party or other Permitted Liens, (i) there are no other Liens or security interests encumbering
the Collateral, and (ii) Debtor will not permit the Collateral to be subject to any adverse lien, security interest or encumbrance
(other than Liens in favor of the Secured Party and Permitted Liens), and Debtor will defend the Collateral against the claims
and demands of all persons at any time claiming the same or any interest therein. No financing statements covering any Collateral
or any proceeds thereof are on file in any public office.

 

(b)       This
Agreement creates in favor of the Secured Party a valid Lien in the Collateral securing the payment and performance of the Obligations,
subject only to the Senior Lender and other Permitted Liens. Upon making the filings of UCC-1 financing statements with the Secretary
of State of the State of Delaware and the State of West Virginia and the Recorder of Deeds in Delaware and West Virginia, all security
interests created hereunder in any Collateral which may be perfected by filing Uniform Commercial Code (“UCC”)
financing statements shall have been duly perfected. Without limiting the generality of the foregoing, except for the filing of
said financing statements, no consent of any third parties and no authorization, approval or other action by, and no notice to
or filing with, any Governmental Authority or regulatory body is required for (i) the execution, delivery and performance of this
Agreement, (ii) the creation or perfection of the Security Interests created hereunder in the Collateral or (iii) the enforcement
of the rights of the Secured Party hereunder.

 

(c)       Debtor
hereby authorizes the Secured Party to file one or more financing statements under the UCC, with respect to the Collateral, with
the proper filing and recording agencies in any jurisdiction deemed proper by it.

(d)       Further
Documentation. At any time and from time to time, Debtor will promptly and duly execute and deliver such further instruments

full benefits of this Agreement and of the rights and powers herein granted. The undersigned Debtor hereby authorizes Secured Party
to file with the appropriate filing office, now or hereafter from time to time, financing statements, continuation statements and
amendments thereto, naming the undersigned as Debtor and covering all of the Collateral of each of the Debtor, including but not
limited to any specific listing, identification or type of all or any portion of the assets of the undersigned.  The undersigned

or amounts due under any contract or document, compromise, compound or settle the same for less than the full amount thereof, release,
wholly or partly, any person liable for the payment thereof, or allow any credit or discount whatsoever thereon other than trade
discounts and rebates granted in the ordinary course of Debtor’s business.

 

(h)       Authority.
Debtor has all requisite corporate or other power and authority to execute this Agreement and to perform all of its obligations

(a)       Powers.
Debtor and Secured Party hereby appoints the officers or agents of Secured Party (each an “Agent”) to act on
behalf of Secured Party, with full power of substitution, as its attorney-in-fact with full irrevocable power and authority in
the place of Debtor and in the name of Debtor or in its own name, so long as an Event of Default has occurred and is continuing,
for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any instrument
which may be necessary or desirable to accomplish the purposes of this Agreement. Without limiting the foregoing, so long as an
Event of Default has occurred and is continuing, Secured Party, in its discretion, will have the right, without notice to, or the
consent of, Debtor, to do any of the following on Debtor’s behalf:

 

(i)       to
pay or discharge any obligations in connection with the Collateral, including license fees and taxes or liens levied or placed
on or threatened against the Collateral;

 

(ii)       to
direct any party liable for any payment under any of the Collateral to make payment of any and all amounts due or to become due
thereunder directly to Secured Party or as Secured Party directs;

 

(iii)       to

(vi)       to
settle, compromise or adjust any suit, action or proceeding described in subsection (v) above and, to give such discharges or releases
in connection therewith as Secured Party may deem appropriate;

 

    	 	6	 

     

    

 

(vii)       to
assign any license or patent right included in the Collateral of a Debtor (along with the goodwill of the business to which any
such license or patent right pertains), throughout the world for such term or terms, on such conditions and in such manner as Secured
Party in their sole discretion determine;

 

(viii)       to
sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral and to take, at Secured
Party’s option and Debtor’s expense, any actions which Secured Party deems necessary to protect, preserve or realize
upon the Collateral and Secured Party’s Liens on the Collateral and to carry out the intent of this Agreement, in each case
to the same extent as if Secured Party were the absolute owners of the Collateral for all purposes;

 

(ix)       to
operate the Business of Debtor using the Collateral and shall have the right to assign, sell, lease or otherwise dispose of and
deliver all or any part of the Collateral, at public or private sale or otherwise, either with or without special conditions or
stipulations, for cash or on credit or for future delivery, in such parcel or parcels and at such time or times and at such place
or places, and upon such terms and conditions as the Agent may deem commercially reasonable, all without (except as shall be required
by applicable statute and cannot be waived) advertisement or demand upon or notice to any Debtor or right of redemption of a Debtor,
which are hereby expressly waived. Upon each such sale, lease, assignment or other transfer of Collateral, the Secured Party, may,
unless prohibited by applicable law which cannot be waived, purchase all or any part of the Collateral being sold, free from and
discharged of all trusts, claims, right of redemption and equities of any Debtor, which are hereby waived and released; and

 

(x)       to
notify any account Debtor and any obligors under instruments or accounts to make payments directly to the Agent, on behalf of the
Secured Party, and to enforce the Debtor’s rights against such account Debtor and obligors.

 

Debtor hereby ratifies
whatever actions Secured Party lawfully does or causes to be done in accordance with this Section 3. This power of attorney will
be a power coupled with an interest and will be irrevocable.

 

(b)       No
Duty on Secured Party’s Part. The powers conferred on Secured Party by this Section 3 are solely to protect Secured
Party’s interest in the Collateral and do not impose any duty upon it to exercise any such powers. Secured Party will be
accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither Secured Party nor
any of their officers, directors, employees or agents will, in the absence of willful misconduct or gross negligence, be responsible
to Debtor for any act or failure to act pursuant to this Section 3.

 

(c)       Application
of Proceeds. The proceeds of any sale, lease or other disposition of the Collateral hereunder or from payments made on account
of any insurance policy insuring any portion of the Collateral shall be applied first, to the expenses of retaking, holding, storing,
processing and preparing for sale, selling, and the like (including, without limitation, any taxes, fees and other costs incurred
in connection therewith) of the Collateral, to the reasonable attorneys’ fees and expenses incurred by the Agent in enforcing
the Secured Party’s rights hereunder and in connection with collecting, storing and disposing of the Collateral, and then
to satisfaction of the Obligations pro rata among the Secured Party (based on then-outstanding principal amounts under the Note
at the time of any such determination), and to the payment of any other amounts required by applicable law, after which the Secured
Party shall pay to Debtor any surplus proceeds. If, upon the sale, license or other disposition of the Collateral, the proceeds
thereof are insufficient to pay all amounts to which the Secured Party are legally entitled, the Debtor will be liable for the
deficiency, together with interest thereon, at the Interest Rate as set forth in the Note, or the lesser amount permitted by applicable
law, and the reasonable fees of any attorneys employed by the Secured Party to collect such deficiency. To the extent permitted
by applicable law, Debtor waives all claims, damages and demands against the Secured Party arising out of the repossession, removal,
retention or sale of the Collateral, unless due solely to the gross negligence or willful misconduct of the Secured Party as determined
by a final judgment (not subject to further appeal) of a court of competent jurisdiction.

 

    	 	7	 

     

    

 

5.       Duty
To Hold In Trust. Upon the occurrence of any Event of Default and at any time thereafter, Debtor shall, upon receipt of any
revenue, income, dividend, interest or other sums subject
to the Security Interests, whether payable pursuant to the Note or otherwise, or of any check, draft, note, trade acceptance or
other instrument evidencing an obligation to pay any such sum, hold the same in trust for the Secured Party, and shall forthwith
endorse and transfer any such sums or instruments, or both, to the Secured Party, pro-rata in proportion to their respective then-currently
outstanding principal amount of Note for application to the satisfaction of the Obligations.

 

6.       Expenses
Incurred by Secured Party. Secured Party shall pay all of its own fees and costs incurred in the preparation of this Agreement
and any related documents. If Debtor fails to perform or comply with any of its agreements or covenants contained in this Agreement,
and Secured Party performs or complies, or otherwise causes performance or compliance with such agreement or covenant in accordance
with the terms of this Agreement, then the reasonable expenses of Secured Party incurred in connection with such performance or
compliance will be jointly and severally payable by Debtor to Secured Party on demand and will constitute Obligations secured by
this Agreement.

 

7.       Remedies.
If a Event of Default has occurred and is continuing, Secured Party may exercise, in addition to all other rights and remedies
granted to it in this Agreement and in any other instrument or agreement relating to the Obligations, all rights and remedies of
a Secured Party under the Delaware Commercial Code (including the Uniform Commercial Code), as amended from time to time (the “Code”).
Without limiting the foregoing, in such circumstances, without demand of performance or other demand, presentment, protest, advertisement
or notice of any kind (except any notice required by law) to or upon Debtor or any other person (all of which demands, defenses,
advertisements and notices are hereby waived), Secured Party may collect, receive, appropriate and realize upon any or all of the
Collateral and/or may sell, lease, assign, give an option or options to purchase or otherwise dispose of and deliver any or all
of the Collateral (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange,
broker’s board or office of Secured Party or elsewhere upon such terms and conditions as Secured Party may deem advisable,
for cash or on credit or for future delivery without assumption of any credit risk. Secured Party will have the right upon any
such public sale or sales and, to the extent permitted by law, upon any such private sale or sales, to purchase all or any part
of the Collateral so sold, free of any right or equity of redemption in Debtor, which right or equity is hereby waived or released.
Secured Party will apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after
deducting all reasonable expenses incurred therein or in connection with the care or safekeeping of any of the Collateral or in
any way relating to the Collateral or the rights of Secured Party under this Agreement (including, without limitation, reasonable
attorneys’ fees and expenses) to the payment in whole or in part of the Obligations, in such order as Secured Party may elect,
and only after such application and after the payment by Secured Party of any other amount required by any provision of law, need
Secured Party account for the surplus, if any, to Debtor. To the extent permitted by applicable law, Debtor waives all claims,
damages and demands it may acquire against Secured Party arising out of the exercise by Secured Party of any of its rights hereunder.
If any notice of a proposed sale or other disposition of Collateral is required by law, such notice will be deemed reasonable and
proper if given at least thirty (30) days before such sale or other disposition. Debtor will remain liable for any deficiency if
the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the reasonable fees
and disbursements of any attorneys employed by Secured Party to collect such deficiency.

 

    	 	8	 

     

    

 

8.       Limitation
on Duties Regarding Preservation of Collateral. The sole duty of Secured Party with respect to the custody, safekeeping and
preservation of the Collateral, under the appropriate Code section or otherwise, will be to deal with it in the same manner as
Secured Party deals with similar property for its own account. Neither Secured Party nor any of its employees, affiliates or agents
will be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or
will be under any obligation to sell or otherwise dispose of any Collateral upon the request of Debtor or otherwise.

 

9.       Powers
Coupled with an Interest. All authorizations and agencies contained in this Agreement with respect the Collateral are irrevocable
and powers coupled with an interest.

 

10.       No
Waiver; Cumulative Remedies. Secured Party will not by any act (except by a written instrument pursuant to Section 11(a)
hereof) of delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced
in any Event of Default under the Note or in any breach of any of the terms and conditions of this Agreement. No failure to exercise,
nor any delay in exercising, on the part of Secured Party, any right, power or privilege hereunder will operate as a waiver thereof.
No single or partial exercise of any right, power or privilege hereunder will preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. A waiver by Secured Party of any right or remedy under this Agreement on any
one occasion will not be construed as a bar to any right or remedy that Secured Party would otherwise have on any subsequent occasion.
The rights and remedies provided in this Agreement are cumulative, may be exercised singly or concurrently and are not exclusive
of any rights or remedies provided by law.

a $650,000 loan (the “Loan”), evidenced by a 10% original issue discount secured promissory note in $720,000

Agreement, all capitalized terms when used herein, shall have the same meanings as they are defined in the Note;

Guarantor is a wholly owned subsidiary of the Company and will derive a material benefit from the proceeds of the Loan.

 

C.       The

D.       In
order to induce the Lender to enter into the financing arrangements with, and make loans and extend credit to the Company, Guarantor
undertakes and agrees as set forth below.

 

1.       Obligations
Guaranteed. To induce Lender to enter into the Transaction Documents and consider extending the Loan to the Company, and for

    	 	2	 

     

    

 

4.       Lender
Actions. Guarantor hereby consents and agrees that Lender may at any time or from time to time in Lender’s discretion
(a) extend or change the time of payment and/or change the manner, place or terms of payment of any or all Obligations, (b) amend,
supplement, restate or replace the Transaction Documents or any related agreements, (c) renew or extend any financing now or hereafter
reflected by the Transaction Documents or the maturity thereof or increase (without limit of any kind and whether related or unrelated)
or decrease loans and extensions of credit to Company, (d) modify the terms and conditions under which loans and/or extensions
of credit may be made to Company, (e) settle, compromise or grant releases for liabilities of the Company, and/or any other Person
or Persons liable with Guarantor for, any Obligations, (f) exchange, compromise, release or surrender, or subordinate or release

securing any or all of the Obligations received by Lender at any time against the Obligations in any order as Lender may determine;
all of the foregoing in such manner and upon such terms as Lender may see fit, and without notice to or further consent from Guarantor,
who hereby agrees to be and shall remain bound upon this Guaranty notwithstanding any such action on Lender’s part.

 

5.       Scope
of Guaranty. The Guaranty is an agreement of suretyship and a guaranty of payment and not of collection. The liability of Guarantor
hereunder is absolute, primary, unlimited and unconditional and shall not be reduced, impaired or affected in any way by reason
of (a) any failure to obtain, retain or preserve, or the lack of prior enforcement of, any rights against any Person or Persons
liable for the Obligations (including Company and Guarantor) or in any property, (b) the invalidity, unenforceability or voidability
of any Obligations or any liens or rights in any property pledged by any Person or Persons, (c) any delay in making demand upon
Company or any delay in enforcing, or any failure to enforce, any rights against Company or any other Person or Persons liable
for any or all of the Obligations or in any property pledged by any Person or Persons, even if such rights are thereby lost, (d)
any failure, neglect or omission on Lender’s part to obtain, perfect or continue any lien upon, protect, exercise rights
against, or realize on, any property of the Company, Guarantor or any other party securing the Obligations, (e) the existence or
nonexistence of any defenses which may be available to the Company with respect to the Obligations, (f) the granting of any waiver
or forbearance at any time and for any period with respect to any performance by Company or any Event of Default or Termination
Event under the Transaction Documents, (g) the commencement of any bankruptcy, reorganization, liquidation, dissolution or receivership
proceeding or case filed by or against Company or any Guarantor or (h) any other fact, event, condition or omission which may give
rise to a suretyship defense. Guarantor promises and undertakes to make all payments hereunder free and clear of any deduction,
offset, defense, claim or counterclaim of any kind.

 

6.       Reinstatement.
If any or all payments or proceeds of property securing any or all of the Obligations made from time to time to Lender with respect
to any obligation hereby guaranteed are at any time recovered from, or repaid by, Lender in whole or in part in any bankruptcy,
reorganization, receivership, insolvency or similar case or proceeding instituted by or against Company, this Guaranty shall continue
to be fully applicable to (or, as the case may be, reinstated to be applicable to) such obligation to the same extent as if the
recovered or repaid payment(s) or proceeds had never been originally paid to the Lender.

 

7.       Cumulative
Remedies. All rights and remedies hereunder and under the Transaction Documents, and related agreements, are cumulative and
not alternative, and Lender may proceed in any order from time to time against Company, Guarantor and/or any other Person or Persons
liable for any or all of the Obligations and their respective assets. Lender shall not have any obligation to proceed at any time
or in any manner against, or exhaust any or all of Lender’s rights against, Company or any other Person or Persons liable
for any or all of the Obligations prior to proceeding against Guarantor hereunder.

 

    	 	3	 

     

    

 

8.       Subrogation.
Any and all rights of any nature of Guarantor to subrogation, reimbursement or indemnity and any right of Guarantor to recourse
to any assets or property of, or payment from, Company or any other Person or Persons liable for any or all of the Obligations
as a result of any payments made or to be made hereunder for any reason shall be unconditionally subordinated to all of Lender’s
rights under the Transaction Documents and Guarantor shall not at any time exercise any of such rights unless and until all of
the Obligations have been unconditionally paid in full. Any payments received by Guarantor in violation of this Section 8 shall
be held in trust for and immediately remitted to Lender.

 

9.       Lender
Records. The Lender’s books and records of any and all of the Obligations, absent manifest error, shall be prima facie
evidence against Guarantor of the indebtedness owing or to become owing to Lender hereunder.

 

10.       Continuing
Surety. This Guaranty shall constitute a continuing surety obligation with respect to all Obligations from time to time incurred
or arising and shall continue in effect until all Obligations are indefeasibly paid and satisfied and the liability of Guarantor
under this Guaranty may not be revoked or terminated.

 

11.       Setoff.
Guarantor agrees that Lender shall have a right of setoff against any and all property of Guarantor now or at any time in Lender’s
possession, including without limitation deposit accounts, and the proceeds thereof, as security for the obligations of Guarantor
hereunder.

 

12.       Acceleration.
If an Event of Default or Termination Event occurs and is continuing, then all of Guarantor’s liabilities of every kind or
nature to Lender hereunder shall, at Lender’s option, become immediately due and payable and Lender may at any time and from
time to time, at Lender’s option (regardless of whether the liability of the Company or any other Person or Persons liable
for any or all of the Obligations has matured or may then be enforced), take any and/or all actions and enforce all rights and
remedies available hereunder or under applicable law to collect Guarantor’s liabilities hereunder.

 

13.       Enforcement
Timing. Failure or delay in exercising any right or remedy against Guarantor hereunder shall not be deemed a waiver thereof
or preclude the exercise of any other right or remedy hereunder. No waiver of any breach of any provision of this Guaranty shall
be construed as a waiver of any subsequent breach or of any other provision.

 

14.       Confession.
 

 

(a)       GUARANTOR
HEREBY IRREVOCABLY AUTHORIZES AND EMPOWERS ANY ATTORNEY(S) OR THE CLERK OF ANY COURT OF RECORD IN THE STATE OF NEW YORK, DELAWARE
OR WEST VIRGINIA, FOLLOWING THE OCCURRENCE OF AN EVENT OF DEFAULT, TO APPEAR FOR GUARANTOR IN ANY SUCH COURT, WITH OR WITHOUT DECLARATION

AND POWER SHALL NOT BE EXHAUSTED BY ANY EXERCISE THEREOF AND JUDGMENT MAY BE CONFESSED FROM TIME TO TIME HEREUNDER AS LENDER MAY
DETERMINE.
