of the Federal Reserve System, in each case as in effect on the Amendment and Restatement Closing Date and on the date of such
use of proceeds.

of principal under the Notes then outstanding, together with all accrued and unpaid interest thereon and, in the case of accelerated
maturity, all premium thereon (including the Make Whole Premium) shall be due and payable.


 


3.2
Interest


 


A.
Base Interest. Subject to the provisions of Section 3.2B, the unpaid principal amount of the Notes shall bear interest from
and after the Amendment and Restatement Closing Date at a base rate of twenty percent (20%) per annum (such interest is referred

of the Notes and, to the extent permitted by Law, any accrued and unpaid interest thereon and any other Obligations (including
the Make Whole Premium) then due and payable shall bear interest at a default rate of the Base Interest plus two percent (2%)
per annum (such interest rate is referred to herein as the “Default Interest Rate”) and be payable in cash

occur of the Amendment and Restatement Closing Date and the last Interest Payment Date on which interest was paid to, and including,

(i)
The Issuer shall not be permitted to prepay all or any portion of the Notes except as expressly permitted under this Section 3.3,

(b)

notice make or cause to be made an irrevocable offer to purchase all outstanding Notes, on a Business Day on or prior to the date

The offer must remain open for at least twenty (20) days following its commencement. The Issuer shall comply with the requirements
of all applicable and any other securities Laws and regulations in connection with the repurchase of Notes pursuant to any offer
to purchase described herein. Notwithstanding the above, if the Note Holders consent to such Change of Control, the Issuer shall
not be required to commence an offer to purchase the outstanding Notes and no Note Holder will have the right to make a request
for such a purchase.

becoming a director subsequent to the Amendment and Restatement Closing Date whose appointment or election by the Board of
Directors of the Issuer or nomination for election by the Issuer’s shareholders was
approved or recommended by a majority of the directors who constitute the Incumbent Board then still in office who were either
directors on the Amendment and Restatement Closing Date, or whose appointment, election or nomination for election was previously
so approved or recommended, shall be considered a member of the Incumbent Board;

outstanding.


 


B.

the deduction or withholding of any Tax from any such payment, then the applicable withholding agent shall be entitled to make
such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority
in accordance with applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Transaction Document
Parties shall be increased as necessary so that, after such deduction or withholding has been made (including such deductions
and withholdings applicable to additional sums payable under this Section), the applicable Note Holder receives an amount equal
to the sum it would have received had no such deduction or withholding been made.



    	 	-28-	 



    	 



     


B.
Payment of Other Taxes by the Issuer. The Issuer shall timely pay to the relevant Governmental Authority in accordance with
applicable Law any Other Taxes.

Note Holder, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes
imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Note Holder or required
to be withheld or deducted from a payment to such Note Holder and any reasonable expenses arising therefrom or with respect thereto,

certificate as to the amount of such payment or liability delivered to the Issuer by a Note Holder shall be conclusive absent
manifest error.

and executed documentation reasonably requested by the Issuer as will permit such payments to be made without withholding or at
a reduced rate of withholding. In addition, any Note Holder, if reasonably requested by the Issuer, shall deliver such other documentation
prescribed by applicable law or reasonably requested by the Issuer as will enable the Issuer to determine whether or not such
Note Holder is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary,
a Note Holder shall not be required to deliver any form or documentation pursuant to this Section 3.6 that such Note Holder is
not legally able to deliver.


 


(ii)
Without limiting the generality of the foregoing:

respect to payments of interest under any Transaction Document, executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E (or applicable
successor form) establishing an exemption from, or reduction of, United States federal withholding Tax pursuant to the “interest”

or IRS Form W-8BEN-E (or applicable successor form) establishing an exemption from, or reduction of, United States federal withholding
Tax pursuant to the “business profits” or “other income” article of such tax treaty;


 


(2)

(3)
in the case of a Foreign Note Holder claiming the benefits of the exemption for portfolio interest under Section 881(c) of the

not a “bank” within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, a “10 percent shareholder”
of the Borrower within the meaning of Section 881(c)(3)(B) of the Internal Revenue Code, or a “controlled foreign corporation”
described in Section 881(c)(3)(C) of the Internal Revenue Code (a “U.S. Tax Compliance Certificate”) and (y)
executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E (or applicable successor form); or


 


(4)
to the extent a Foreign Note Holder is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI,
IRS Form W-8BEN or IRS Form W-8BEN-E (or applicable successor form), IRS Form W-9, U.S. Tax Compliance Certificates and/or other
certification documents from each beneficial owner, as applicable; provided that if the Foreign Note Holder is a partnership and

Note Holder may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit D on behalf of each such direct
and indirect partner; and


 


(c)
if a payment made to a Note Holder under any Transaction Document would be subject to United States federal withholding Tax imposed
by FATCA if such Note Holder were to fail to comply with the applicable reporting requirements of FATCA (including those contained
in Section 1471(b) or 1472(b) of the Code, as applicable), such Note Holder shall deliver to the Issuer at the time or times prescribed
by law and at such time or times reasonably requested by the Issuer such documentation prescribed by applicable Law (including
as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such additional documentation reasonably requested

notify the Issuer in writing of its legal inability to do so.

F.
Treatment of Certain Refunds. If any Note Holder determines, in its sole discretion exercised in good faith, that it has received
a refund of any Taxes as to which it has been indemnified pursuant to this Section 3.6 (including by the payment of additional
amounts pursuant to this Section 3.6), it shall pay to the Issuer an amount equal to such refund (but only to the extent of indemnity
payments made under this Section 3.6 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses
(including Taxes) of such Note Holder and without interest (other than any interest paid by the relevant Governmental Authority
with respect to such refund). The Issuer, upon the request of such Note Holder, shall repay to such Note Holder the amount paid
over pursuant to this Section 3.6F (plus any penalties, interest or other charges imposed by the relevant Governmental Authority)
in the event that such Note Holder is required to repay such refund to such Governmental Authority. Notwithstanding anything to
the contrary in this Section 3.6F, in no event will the Note Holder be required to pay any amount to the Issuer pursuant to this
Section 3.6F the payment of which would place the Note Holder in a less favorable net after-Tax position than the Note Holder
would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise
imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This Section 3.6F
shall not be construed to require any Note Holder to make available its Tax returns (or any other information relating to its
Taxes that it deems confidential) to the Issuer or any other person.


 


G.
Survival. Each Party’s obligations under this Section 3.6 shall survive any assignment of rights by a Note Holder, the
repayment, satisfaction or discharge of all obligations under any Transaction Document.

None of the Issuer, its Subsidiaries, their Affiliates and any Person acting on their behalf will take any action or steps referred

J.
SEC Documents; Financial Statements. Since December 11, 2013, the Issuer (and its predecessor) has timely filed all reports,

therein and financial statements, notes and schedules thereto and documents incorporated by reference therein being hereinafter
referred to as the “SEC Documents”). The Issuer has delivered to the Note Purchaser or its respective representatives
true, correct and complete copies of the SEC Documents not available on the EDGAR system. As of their respective filing dates,
the SEC Documents complied in all material respects with the requirements of the Exchange Act and the rules and regulations of
the SEC promulgated thereunder applicable to the SEC Documents, and none of the SEC Documents, at the time they were filed with
the SEC, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or
necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.
As of their respective filing dates, the financial statements of the Issuer included in the SEC Documents complied as to form
in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect
thereto. Such financial statements have been prepared in accordance with GAAP, consistently applied, during the periods involved
(except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited
interim statements, to the extent they may exclude footnotes or may be condensed or summary statements) and fairly present in
all material respects the financial position of the Issuer as of the dates thereof and the results of its operations and cash
flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments). No other
information provided by or on behalf of the Issuer to the Note Purchaser which is not included in the SEC Documents, contains
any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein,
in the light of the circumstance under which they are or were made, not misleading (it being recognized that financial projections
or forecasts by or on behalf of the Issuer are not to be viewed as facts and that the actual results during the period or periods
covered by any such financial projections or forecasts may differ from the projected or forecasted results). The Issuer is not
currently contemplating to amend or restate any of the financial statements (including without limitation, any notes or any letter
of the independent accountants of the Issuer with respect thereto) included in the SEC Documents (the “SEC Financial
Statements”), nor is the Issuer currently aware of facts or circumstances which would require the Issuer to amend or
restate any of the SEC Financial Statements, in each case, in order for any of the SEC Financial Statements to be in compliance
with GAAP and the rules and regulations of the SEC. The Issuer has not been informed by its independent accountants that they
recommend that the Issuer amend or restate any of the SEC Financial Statements or that there is any need for the Issuer to amend
or restate any of the SEC Financial Statements.

13a-15 under the Exchange Act) that are effective in ensuring that information required to be disclosed by the Issuer in the reports
that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified

by the Issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Issuer’s

to allow timely decisions regarding required disclosure. Except as disclosed in the SEC Documents, during the twelve months prior

to perform any of its obligations under the Transaction Documents. In addition, on or prior to the Amendment and Restatement Closing

discussions, the Issuer has no reason to believe that it will need to restate any such financial statements or any part thereof.

the Issuer’s outstanding voting equity securities, calculated on the basis of voting power, nor any promoter (as that term
is defined in Rule 405 under the Securities Act) connected with the Issuer in any capacity at the time of sale (collectively “Issuer
Covered Persons”) is subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i)
to (viii) under the Securities Act (a “Disqualification Event”). The Issuer has exercised reasonable care to
determine whether any Issuer Covered Person is subject to a Disqualification Event. The Issuer has complied, to the extent applicable,
with its disclosure obligations under Rule 506(e), and has furnished to the Note Purchaser a copy of any disclosures provided
thereunder.

R.
Other Covered Persons. Except as disclosed on Schedule 5.2R, the Issuer is not aware of any Person that has been or will be
paid (directly or indirectly) remuneration for solicitation of the Note Purchaser or potential purchasers in connection with the
sale of any Regulation D Securities.


 


S.
Approved Budget. The Approved Budget is based on good faith estimates and assumptions believed by management of the Issuer
to be reasonable and fair in light of current conditions and facts known to the Issuer at the time delivered. The management of
the Issuer believed, as of the date when prepared, that such Approved Budget was reasonable and attainable, it being recognized
by the Note Purchaser, however, that projections as to future events are not to be viewed as facts or guaranties of future performance,
that actual results during the period or periods covered by such projections may differ from the projected results.

No
Subject Company has any Contingent Obligation, contingent liability or liability for Taxes, long-term lease or forward or long-term

and legal leasehold interests) to all of its respective properties and assets, including all its real and personal properties
material to its business, in each case, free and clear of all Liens, other than Permitted Liens (except as otherwise consented
to by the Note Holders) and except to the extent that the failure to have such title could not reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect. All Lien searches have been conducted consistent with the policy
of the Issuer and to the best of the Issuer’s knowledge, indicate that the properties and assets are free of Liens, and
to the extent any such Liens exist, such Liens could not reasonably be expected to result in a Material Adverse Effect.

Material Adverse Effect or (ii) questioning the validity or enforceability or otherwise affecting this Agreement or any other

may be added thereto for non-payment thereof except for those being contested in accordance with Permitted Contest Procedures
or to the extent that such failure to pay such Taxes or file such Tax Returns could not be reasonably expected to have a Material
Adverse Effect. As of the Amendment and Restatement Closing Date, except as set forth on Schedule 5.7, no Tax Return is under
audit or examination by any Governmental Authority and no written notice of such an audit or examination or any written assertion
of any claim for Taxes has been given or made by any Governmental Authority. No Subject Company has participated in a “reportable

such Equity Interests, as applicable, including the proposed price therefor and the proposed date and time of the closing therefor.
Upon receipt of a Financing ROFO Notice, the Note Holders shall have twenty (20) Business Days (the “Financing ROFO Option

prospective third-party purchaser than those specified in the Financing ROFO Notice, but only to the extent that such third-party
transaction occurs within sixty (60) days after expiration of the Financing ROFO Option Period. Any such Indebtedness or Equity

(the “Proxy Statement”) to obtain such approval of the Note Conversion at the Stockholders Meeting and (iii)
distribute the Proxy Statement to stockholders and seek proxies in favor of the Note Conversion to be voted at the Stockholders
Meeting. The Proxy Statement shall contain all information required by the Securities Exchange Act of 1934 and the rules of the
SEC relating to the Stockholders Meeting and the Note Conversion. The Issuer shall cooperate and consult with the Note Holder
in preparing the Proxy Statement and shall not file the Proxy Statement or any amendment or supplement thereto (or the form of
proxy) with the SEC, or submit any correspondence or other document relating to the Proxy Statement to the SEC staff, without
first providing a copy of such document, in draft form, to the Note Holder and affording the Note Holder a reasonable opportunity
to review and comment thereon. The Issuer shall consider any Note Holder comments in good faith and use reasonable efforts to
incorporate such comments and in no event shall the Issuer file any such document with the SEC, or submit any such document to
the SEC staff, if the Note Holder shall have objected thereto. The Issuer shall use diligent efforts to resolve, and shall diligently
consult and cooperate with the Note Holder in resolving, any SEC staff comments relating to the Proxy Statement as promptly as

of any material portion of the assets of the Issuer, an acquisition by a third party of the Issuer’s Common Stock, or any
other transaction that would be inconsistent with the Note Conversion; provided, however, that (i) the Issuer shall be permitted
to take any of the foregoing actions so long as all outstanding Notes are repaid, and all accrued and unpaid interest thereon
and the applicable Make Whole Premium are paid, concurrently with the consummation thereof and (ii) the restrictions in this paragraph
shall not apply to the extent that, at any time prior to obtaining the Stockholder Approval, the Issuer’s Board determines
in good faith, based on written advice from the Company’s outside legal counsel, that complying with any such restriction
would reasonably be expected to constitute a breach of the fiduciary duties of the Issuer’s Board of Directors to its stockholders
under applicable Law.


 


D.
The Issuer shall offer an option to holders of Common Stock (excluding the Note Purchaser) that qualify as “accredited

providing a copy of such document, in draft form, to the Note Holder and affording the Note Holder a reasonable opportunity to
review and comment thereon, and the Issuer shall consider any Note Holder comments on the 8-K Filing in good faith and use reasonable
efforts to incorporate such comments. Except for the foregoing, neither the Issuer, any other Subject Company nor the Note Purchaser
shall issue any press releases or any other public statements with respect to the transactions contemplated hereby; provided,
however, that the Issuer shall be entitled, without the prior approval of the Note Purchaser, to make any press release or other
public disclosure with respect to such transactions, (i) in substantial conformity with the 8-K Filing and contemporaneously therewith,
and (ii) as is required by applicable law and regulations or Nasdaq rules (provided that the Note Purchaser shall be consulted
by the Issuer in connection with any such press release or other public disclosure a reasonable period prior to its release).

for the purpose of issuance, no less than the maximum number of Shares issuable upon conversion of the Notes then outstanding

and reserve a sufficient number of Shares, including, without limitation, calling a special meeting of stockholders to authorize
additional shares of Common Stock to meet the Issuer’s obligations under this Section 6.17, in the case of an insufficient
number of authorized shares, obtain stockholder approval of an increase in such authorized number of shares, and voting the management
shares of the Issuer in favor of an increase in the authorized shares of the Issuer to ensure that the number of authorized shares
is sufficient to meet the Required Reserved Amount.

detail of the Initial Budget and otherwise in form and substance satisfactory to the Note Purchaser (the “Updated Budget”).

the subsequent purchaser, assignee, transferee or participant has provided to the Issuer representations and warranties in the
form of Section 9.22M.


 


(ii)
The Issuer hereby acknowledges and agrees that any sale, assignment, transfer or grant of the Notes will give rise to a direct
obligation of the Issuer to the transferee, assignee or purchaser. Except with the prior written consent of the Note Holders,
no Note Holder (other than the Note Purchaser) shall have a right to consent or vote on any matters hereunder other than with
respect to:


 


(a)
the extension of any date of any payment of principal or interest in respect of any Note;


 


(b)
the reduction of the amount of any such payment of principal;


 



    	 	-73-	 



    	 



     


(c)
a decrease in the rate of interest on any Note (as specified in the Note) other than any imposition of a default rate of interest;


 


(d)
the termination of any Transaction Document except in accordance with its terms; or


 


(e)
release of all or substantially all of the Collateral securing the Notes other than in accordance with the terms of the Transaction
Documents;


 


provided,
however, that the restrictions set forth in this Section 9.1B(ii) shall not apply in respect of such waiver or amendment
required by any applicable Law or request of any governmental authority (including in connection with any actual or proposed reorganization,
restructuring, bankruptcy, insolvency, or other similar event affecting the Issuer or any other party to the Security Agreements.


 


(iii)
Each Note Holder that sells a participation shall (i) acting solely for this purpose as a non-fiduciary agent of the Issuer, maintain
a register on which it enters the name and address of each participant and the principal amounts (and stated interest) of each
participant’s interest in the Notes (the “Participant Register”), and (ii) obtain from each Participant
the documentation prescribed by Section 3.6E as if such participant were a Note Holder; provided that no Note Holder shall have
any obligation to disclose all or any portion of the Participant Register (including the identity of any participant or any information
relating to a participant’s interest in any loans) to any Person except to the extent that such disclosure is necessary
to establish that such loan is in registered form under Treasury Regulation Section 5f.103-1(c). The entries in the Participant
Register shall be conclusive absent manifest error, and such Note Holder shall treat each person whose name is recorded in the
Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary.
For the avoidance of doubt, the Transaction Document Parties agree that each participant shall be entitled to the benefits of
Section 3.6 (subject to the requirements and limitations therein, including the requirements under Section 3.6E (it being understood
that the documentation required under Section 3.6E shall be delivered to the participating Note Holder)) to the same extent as
if it were a Note Holder and had acquired its interest by assignment; provided that such participant shall not be entitled to
receive any greater payment under Section 3.6 with respect to any participation than its participating Note Holder would have
been entitled to receive, except to the extent such entitlement to receive a greater payment results from a change in law that
occurs after the participant acquired the applicable participation.


 


C.
Procedures. Upon surrender of any Note at the principal office of the Issuer for registration of transfer or exchange (for
registration of transfer, duly endorsed or accompanied by a written instrument of transfer duly executed by the registered holder
of such Note or his attorney duly authorized in writing and accompanied by the address for notices and payment instructions of
each transferee of such Note or part thereof and a representation by each such transferee that such transferee is a Permitted
Transferee), the Issuer shall execute and deliver, at the Issuer’s expense, one or more new Notes (as requested by the holder
thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Note.
Each such new Note shall be substantially in the form attached in Exhibit A and shall be payable to such Person as such holder
may request. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered
Note or dated the date of the surrendered Note if no interest shall have been paid thereon.

or mutilation of any Note, and (i) in the case of loss, theft or destruction, upon receipt of an unsecured agreement of indemnity
or, in the case of any Note Holder that is not an institutional investor, an indemnity bond, in each case in such reasonable amount
as the Issuer shall determine, or (ii) in the case of mutilation, upon surrender and cancellation thereof, the Issuer at its own
expense shall execute and deliver, in lieu thereof, a new Note, dated and bearing interest from the date to which interest shall
have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated
Note if no interest shall have been paid thereon.

9.3
Indemnity


 


A.
In addition to the payment of expenses pursuant to Section 9.2, the Issuer agrees to defend (subject to Indemnitees’
selection of counsel), indemnify, pay and hold harmless each Note Holder and its Affiliates and its respective officers, directors,
employees, beneficiaries, shareholders and agents (collectively called the “Indemnitees”) from and against
any and all other Indemnified Liabilities; provided that the Issuer shall not have any obligation to any Indemnitee hereunder
with respect to any Indemnified Liabilities to the extent such Indemnified Liabilities arise from (i) the gross negligence or
willful misconduct of that Indemnitee as determined by a final judgment of a court of competent jurisdiction or (ii) a dispute
among Indemnitees not arising from the actions or omissions of the Issuer. In no event shall any Indemnitee be liable to the Issuer
for any consequential, indirect, special or punitive damages other than payable with respect to a third party claim.


 


B.
As used herein, “Indemnified Liabilities” means any and all liabilities, obligations, losses, damages (including
natural resource damages), penalties, actions, judgments, suits, claims, costs (including the costs of any investigation, study,
sampling, testing, abatement, cleanup, removal, remediation, or other response action necessary to remove, remediate, clean up,
or abate any Hazardous Materials), expenses and disbursements of any kind or nature whatsoever (including the reasonable and documented
fees, expenses and disbursements of counsel for such Indemnitees in connection with any investigative, administrative or judicial
proceeding commenced or threatened by any Person, whether or not any such Indemnitee shall be designated as a party or a potential
party thereto, and any fees or expenses incurred by Indemnitees in enforcing this indemnity), and whether based on any federal,
state, or foreign Laws (including securities and commercial Laws and Environmental Laws), on common Law or equitable cause or
on contract or otherwise, that may be imposed on, incurred by, or asserted against any such Indemnitee, in any manner relating
to or arising out of:


 


(i)
this Agreement or the other Transaction Documents, or the transactions contemplated hereby or thereby (including the Note Purchaser’s
agreement to purchase the Notes hereunder or the use or intended use of proceeds thereof) or any enforcement of any of the Transaction
Documents (including any sale of, collection from, or other realization upon any of the Collateral);


 


(ii)
any statement made by the Note Purchaser to the Issuer during the negotiation of this Agreement or the other Transaction Documents
prior to the Amendment and Restatement Closing Date; or


 


(iii)
any Environmental Claim or any condition resulting from Hazardous Materials relating to or arising from, directly or indirectly,
any past or present activity, operation, land ownership or practice of the Issuer or any other Subject Company.


 


C.
To the extent that the undertaking to indemnify, pay and hold harmless set forth in Section 9.3A above may be unenforceable
because it is violative of any applicable Law or public policy, the Issuer shall contribute the maximum portion which it is permitted
to pay and satisfy under applicable Law to the payment and satisfaction of all Indemnified Liabilities incurred by the Indemnitees
or any of them.

No
amendment, modification, termination or waiver of any provision of this Agreement or any other Transaction Document or consent
to any departure by the Issuer therefrom shall in any event be effective without the written concurrence of the Note Holders representing
greater than fifty percent (50%) of then outstanding principal amount of the Notes (provided that the consent of all Note Holders
shall be required for any amendment, modification, termination or waiver would have the effect of increasing the Commitments,
reducing the outstanding principal amount or reducing the rate of interest or any fees payable hereunder or postpone the date
of payment or amending this Section 9.4) and, if intended to bind the Issuer, of the Issuer. Any waiver or consent shall be effective
only in the specific instance and for the specific purpose for which it was given. No notice to or demand on the Issuer in any
case shall entitle the Issuer to any other or further notice or demand in similar or other circumstances. Any amendment, modification,
termination, waiver or consent effected in accordance with this Section 9.4 with the written concurrence of the Note Holders shall
be binding upon each holder of the Notes at such time outstanding, each future holder of the Notes, and, if signed by Issuer,

any security interests or exercises its rights of set-off, and such payment or the proceeds of such enforcement or set-off or
any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid
to a trustee, receiver or any other party under any bankruptcy Law, any other state or federal Law, common Law or any equitable
cause, then, to the extent of such recovery, the obligation or part thereof originally intended to be satisfied, and all Liens,
rights and remedies therefor or related thereto, shall be revived and continued in full force and effect as if such payment had
not been made or such enforcement or set-off had not occurred.


 


9.14
Set-Off

addition to any rights now or hereafter granted under applicable Law and not by way of limitation of any such rights, upon the
occurrence and during the continuance of any Event of Default, each Note Holder is hereby authorized by the Issuer at any time

of deposit, whether matured or unmatured, but not including trust accounts) and any other Indebtedness at any time held or owing
by that Note Holder to or for the credit or the account of the Issuer against and on account of the obligations and liabilities
of the Issuer to that Note Holder under this Agreement and the other Transaction Documents, including all claims of any nature
or description arising out of or connection with this Agreement or any other Transaction Document, irrespective of whether or
not, (i) that Note Holder shall have made any demand hereunder, or (ii) the principal of or the interest on the Notes or any other
amounts due hereunder shall have become due and payable pursuant to Section 8 and although said obligations and liabilities, or
any of them, may be contingent or unmatured.

9.15
Ratable Sharing


 


A.
The Note Holders hereby agree among themselves that if any of them shall, whether by voluntary payment, by realization upon
security, through the exercise of any right of set-off or banker’s lien, by counterclaim or cross action or by the enforcement
of any right under the Transaction Documents or otherwise, or as adequate protection of a deposit treated as cash collateral under
the Bankruptcy Code or any similar law, receive payment or reduction of a proportion of the aggregate amount of principal, interest,
fees and other amounts then due and owing to that Note Holder hereunder or under the other Transaction Documents (collectively,
the “Aggregate Amounts Due” to such Note Holder) which is greater than the proportion received by any other
Note Holder in respect of the Aggregate Amounts Due to such other Note Holder, then the Note Holder receiving such proportionately
greater payment shall:


 


(i)
notify each other Note Holder of the receipt of such payment; and


 


(ii)
apply a portion of such payment to purchase participations (which it shall be deemed to have purchased from each seller of a participation
simultaneously upon the receipt by such seller of its portion of such payment) in the Aggregate Amounts Due to the other Note
Holders so that all such recoveries of Aggregate Amounts Due shall be shared by all Note Holders in proportion to the Aggregate
Amounts Due to them,


 


provided
that if all or part of such proportionately greater payment received by such purchasing Note Holder is thereafter recovered from
such Note Holder upon the bankruptcy or reorganization of the Issuer or otherwise, those purchases shall be rescinded and the
purchase prices paid for such participations shall be returned to such purchasing Note Holder ratably to the extent of such recovery,
but without interest.


 


B.
The Issuer expressly consents to the arrangement contemplated in Section 9.15A and agrees that any holder of a participation
so purchased may exercise any and all rights of banker’s lien, set-off or counterclaim with respect to any and all monies
owing by the Issuer to that holder with respect thereto as fully as if that holder were owed the amount of the participation held
by that holder.

the event any provision of this Agreement and any of the other Transaction Documents shall conflict, the provisions of this Agreement
shall govern.


 


9.21

Representations of the Note Purchaser


 


The
Note Purchaser represents and warrants that, as of the Amendment and Restatement Closing Date:


 


A.
Organization; Authority. Such Note Purchaser is an entity duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization with the requisite power and authority to enter into and to consummate the transactions
contemplated by this Agreement and the Additional Transaction Documents to which it is a party and otherwise to carry out its
obligations hereunder and thereunder.


 



    	 	-82-	 



    	 



     


B.
No Public Sale or Distribution. Such Note Purchaser is, (i) acquiring the Notes, and (ii) upon conversion of the Notes will
acquire the Shares issuable pursuant to the Notes for its own account and not with a view towards, or for resale in connection
with, the public sale or distribution thereof, except pursuant to sales registered or exempted under the Securities Act; provided,
however, by making the representations herein, such Note Purchaser does not agree to hold any of the Notes for any minimum or
other specific term and reserves the right to dispose of the Notes at any time in accordance with or pursuant to a registration
statement or an exemption under the Securities Act and in accordance with the terms of this Agreement and the Additional Transaction
Documents. Such Note Purchaser is acquiring the Notes hereunder in the ordinary course of its business. Such Note Purchaser does
not presently have any agreement or understanding, directly or indirectly, with any Person to distribute any of the Notes (or
the Shares issuable upon conversion thereof).


 


C.
Accredited Investor Status. Such Note Purchaser is an “accredited investor” as that term is defined in Rule 501(a)
of Regulation D under the Securities Act.


 


D.
Reliance on Exemptions. Such Note Purchaser understands that the Notes (and the Shares issuable upon conversion thereof) are
being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and
state securities Laws and that the Issuer is relying in part upon the truth and accuracy of, and such Note Purchaser’s compliance
with, the representations, warranties, agreements, acknowledgments and understandings of such Note Purchaser set forth herein
in order to determine the availability of such exemptions and the eligibility of such Note Purchaser to acquire the Notes (and
the Shares issuable upon conversion thereof).


 


E.
Information. Such Note Purchaser and its advisors, if any, have been furnished with all materials relating to the business,
finances and operations of the Issuer and materials relating to the offer and sale of the Notes (and the Shares issuable upon
conversion thereof) that have been requested by such Note Purchaser. Such Note Purchaser and its advisors, if any, have been afforded
the opportunity to ask questions of the Issuer. Neither such inquiries nor any other due diligence investigations conducted by
such Note Purchaser or its advisors, if any, or its representatives shall modify, amend or affect such Note Purchaser’s
right to rely on the Issuer’s representations and warranties contained herein. Such Note Purchaser understands that its
investment in the Notes (and the Shares issuable upon conversion thereof) involves a high degree of risk. Such Note Purchaser
has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect
to its acquisition of the Notes (and the Shares issuable upon conversion thereof).


 


F.
No Governmental Review. Such Note Purchaser understands that no United States federal or state agency or any other government
or governmental agency has passed on or made any recommendation or endorsement of the Notes (or the Shares issuable upon conversion
thereof) or the fairness or suitability of the investment in the Notes (or the Shares issuable upon conversion thereof) nor have
such authorities passed upon or endorsed the merits of the offering of the Notes (or the Shares issuable upon conversion thereof).


 



    	 	-83-	 



    	 



     


G.
Transfer or Resale. Such Note Purchaser understands that except as provided in the Registration Rights Agreement:


 


(i)
the Notes (and the Shares issuable upon conversion thereof) have not been and are not being registered under the Securities Act
or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless:


 


(a)
subsequently registered thereunder;


 


(b)
such Note Purchaser shall have delivered to the Issuer an opinion of counsel, in a form reasonably acceptable to the Issuer, to
the effect that such Notes or Shares issued upon conversion thereof to be sold, assigned or transferred may be sold, assigned
or transferred pursuant to an exemption from such registration; or


 


(c)
such Note Purchaser provides the Issuer with reasonable assurance that such Securities can be sold, assigned or transferred pursuant
to Rule 144;


 


(ii)
any sale of the Securities made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further,
if Rule 144 is not applicable, any resale of the Notes or Shares issuable upon conversion thereof under circumstances in which
the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities
Act) may require compliance with some other exemption under the Securities Act or the rules and regulations of the SEC promulgated
thereunder; and


 


(iii)
neither the Issuer nor any other Person is under any obligation to register the Notes or the Shares issuable upon conversion thereof
under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder.


 


H.
Legends. Such Note Purchaser understands that the certificates or other instruments representing the Notes and, until such
time as the resale of the Shares issuable upon conversion of the Notes have been registered under the Securities Act as contemplated
by the Registration Rights Agreement, the stock certificates representing any Shares issued upon conversion of the Notes, except
as set forth below, shall bear any legend as required by the “blue sky” laws of any state and a restrictive legend
in substantially the following form (and a stop-transfer order may be placed against transfer of such stock certificates):


 


NEITHER
THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE CONVERTIBLE
HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT
BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL, IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION
IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING,

the amount of the Initial Notes outstanding on the Amendment and Restatement Closing Date, together with all interest accrued
and accruing thereon (it being understood that all such interest shall constitute Additional Notes issued on the Amendment and
Restatement Closing Date), and all fees, costs, expenses and other charges relating thereto (collectively, the “Existing

of any kind, nature or description whatsoever


 


B.
The Issuer, on behalf of itself and the other Subject Companies, hereby acknowledges, confirms and agrees that the Note Holders

any of the other Transaction Documents or otherwise granted to or held by the Note Purchaser or any Note Holder.


 


C.
The Liens and security interests of the Note Holders in the Collateral shall be deemed to be continuously granted and perfected
from the earliest date of the granting and perfection of such Liens and security interests, whether under the Original Note Facility
Agreement, this Agreement or any other Transaction Document (as defined in the Original Note Facility Agreement or this Agreement).


 



    	 	-88-	 



    	 



     


D.
The Issuer, on behalf of itself and the other Subject Companies, hereby acknowledges, confirms and agrees that (in each case
excepted as modified herein) (a) the Original Note Facility Agreement and each other Transaction Document (as defined in the Original
Note Facility Agreement) has been duly executed and delivered by the Subject Companies party thereto and is in full force and
effect as of the Amendment and Restatement Closing Date and (b) the agreements and obligations of the Subject Companies contained
in the Original Note Facility Agreement and each other Transaction Document to the extent a party thereto constitute the legal,
valid and binding obligations of the Subject Companies, enforceable against each of them in accordance with their respective terms
and no Subject Company has a valid defense to the enforcement of such obligations and (c) the Note Purchase and the Note Holders
are entitled to all of the rights and remedies provided for in the Original Note Facility Agreement.


 


E.

shall impair or adversely affect the continuation of the liability of Subject Companies for the Obligations heretofore granted,
pledge and/or assigned to or for the benefit of the Note Purchaser or any Note Holder. The amendment and restatement contained
herein shall not, in any manner, be construed to constitute payment of, or impair, limit, cancel or extinguish, or constitute
a novation in respect of, the Indebtedness and other obligations and liabilities of Subject Companies evidenced by or arising
under the Original Note Facility Agreement and the other Transaction Documents, and the Liens and security interests securing
such Indebtedness and other obligations and liabilities, which shall not in any manner be impaired, limited, terminated, waived
