(a)
At any time after the date that is one-hundred eighty (180) days after the date of this Agreement, holders of at least twenty
percent (20%) of the Registrable Securities then outstanding and held by Note Holders or their assignees pursuant to Section 15
(“Note Holder Parties”) may request registration under the Securities Act of all or any portion of their Registrable
Securities on Form S-1 or any successor form thereto (each a “Long-Form Registration”). Each request for a
Long-Form Registration shall specify the approximate number of Registrable Securities required to be registered. Upon receipt
of such request, the Issuer shall promptly (but in no event later than five (5) Business Days following receipt thereof) deliver
notice of such request to all other holders of Registrable Securities who shall then have five (5) Business Days from the date
such notice is given to notify the Issuer in writing of their desire to be included in such registration. Each holder of Registrable
Securities who is a Note Holder Party agrees that the fact that such a notice has been delivered shall constitute confidential
information. The Issuer shall cause a Registration Statement on Form S-1 (or any successor form) to be filed within seventy-five
(75) days after the date on which the initial request is given and shall use its reasonable best efforts to cause such Registration
Statement to be declared effective by the SEC as soon as practicable thereafter.


 




    	3



    	 



    

 


(b)
The Issuer shall use its reasonable best efforts to qualify and remain qualified to register securities under the Securities Act
pursuant to a Registration Statement on Form S-3 or any successor form thereto. At such time as the Issuer shall have qualified
for the use of a Registration Statement on Form S-3, the holders of Registrable Securities who are Note Holder Parties shall have
the right to request registrations of their Registrable Securities on Form S-3 or any similar short-form registration (each a
“Short-Form Registration” and, together with each Long-Form Registration, a “Demand Registration”).
Each request for a Short-Form Registration shall specify the approximate number of Registrable Securities requested to be registered.
Upon receipt of any such request, the Issuer shall promptly (but in no event later than five (5) Business Days following receipt
thereof) deliver notice of such request to all other holders of Registrable Securities who shall then have five (5) Business Days
from the date such notice is given to notify the Issuer in writing of their desire to be included in such registration. The Issuer
shall cause a Registration Statement on Form S-3 (or any successor form) to be filed within forty-five (45) days after the date
on which the initial request is given and shall use its reasonable best efforts to cause such Registration Statement to be declared
effective by the SEC as soon as practicable thereafter. The Issuer shall not be required to effect a Long-Form Registration or
a Short Form Registration more than five times in the aggregate for the holders of Registrable Securities held by the Note Holder
Parties as a group; provided, that a Registration Statement shall not count as a Long-Form Registration requested under
Section 2(a) or as a Short-Form Registration under this Section 2(b) unless and until it has become effective and the holders
requesting such registration are able to register and sell at least seventy-five percent (75%) of the Registrable Securities requested
to be included in such registration.


 


(c)
The Issuer shall not be obligated to effect any Demand Registration within a hundred and twenty (120) days after the effective
date of a previous Demand Registration or a previous Piggyback Registration in which holders of Registrable Securities were permitted
to register, and actually sold, all of the shares of Registrable Securities requested to be included therein. The Issuer may postpone
for up to twenty (20) Business Days the filing or effectiveness of a Registration Statement for a Demand Registration if the Issuer’s
Board of Directors determines in its reasonable good faith judgment that such Demand Registration would (i) materially interfere
with a significant acquisition, corporate organization or other similar transaction involving the Issuer; (ii) require premature
disclosure of material information that the Issuer has a bona fide business purpose for preserving as confidential; or (iii) render
the Issuer unable to comply with requirements under the Securities Act or Exchange Act; provided, that in such event the
holders of a majority of the Registrable Securities initiating such Demand Registration shall be entitled to withdraw such request
and, if such request is withdrawn, such Demand Registration shall not count as one of the permitted Demand Registrations hereunder
and the Issuer shall pay all registration expenses in connection with such registration. The Issuer may delay a Demand Registration
hereunder only twice in any period of twelve (12) consecutive months.


 




    	4



    	 



    

 


(d)
If the holders of the Registrable Securities initially requesting a Demand Registration elect to distribute the Registrable Securities
covered by their request in an underwritten offering, they shall so advise the Issuer as a part of their request made pursuant
to Section 2(a) or Section 2(b), and the Issuer shall include such information in its notice to the other holders of Registrable
Securities. The holders of a majority of the Registrable Securities initially requesting the Demand Registration shall select
the investment banking firm or firms to act as the managing underwriter or underwriters in connection with such offering; provided,
that such selection shall be subject to the consent of the Issuer, which consent shall not be unreasonably withheld or delayed.


 


(e)
The Issuer shall not include in any Demand Registration any securities which are not Registrable Securities without the prior
written consent of the holders of a majority of the Registrable Securities included in such registration, which consent shall
not be unreasonably withheld or delayed. If a Demand Registration involves an underwritten offering and the managing underwriter
of the requested Demand Registration advises the Issuer and the holders of Registrable Securities in writing that in its opinion
the number of shares of Common Stock proposed to be included in the Demand Registration, including all Registrable Securities
and all other shares of Common Stock proposed to be included in such underwritten offering, exceeds the number of shares of Common
Stock which can be sold in such underwritten offering and/or the number of shares of Common Stock proposed to be included in such
registration would adversely affect the price per share of the Registrable Securities proposed to be sold in such underwritten
offering, the Issuer shall include in such Demand Registration (i) first, the number of shares of Common Stock that the holders
of Registrable Securities who are Note Holder Parties propose to sell, (ii) second, the number of shares of Common Stock that
the other holders of Registrable Securities propose to sell and (iii) third, the number of shares of Common Stock proposed to
be included therein by any other Persons (including shares of Common Stock to be sold for the account of the Issuer and/or other
holders of Common Stock) allocated among such Persons in such manner as they may agree. If the managing underwriter determines
that less than all of the Registrable Securities proposed to be sold can be included in such offering, then the Registrable Securities
that are included in such offering shall be allocated pro rata among the respective holders thereof on the basis of the number
of Registrable Securities owned by each such holder.


 


3.
PIGGYBACK REGISTRATION


 


(a)
Whenever the Issuer proposes to register any shares of its Common Stock under the Securities Act (other than a registration effected
solely to implement an employee benefit plan or a transaction to which Rule 145 of the Securities Act is applicable, or a Registration
Statement on Form S-4, S-8 or any successor form thereto or another form not available for registering the Registrable Securities
for sale to the public), whether for its own account or for the account of one or more stockholders of the Issuer and the form
of Registration Statement to be used may be used for any registration of Registrable Securities (a “Piggyback Registration”),
the Issuer shall give prompt written notice (in any event no later than ten (10) Business Days prior to the filing of such Registration
Statement) to the holders of Registrable Securities of its intention to effect such a registration and, subject to Section 3(b)
and Section 3(c), shall include in such registration all Registrable Securities with respect to which the Issuer has received
written requests for inclusion from the holders of Registrable Securities within five (5) Business Days after the Issuer’s
notice has been given to each such holder. Each holder of Registrable Securities agrees that the fact that such a notice has been
delivered shall constitute confidential information. A Piggyback Registration shall not be considered a Demand Registration for
purposes of Section 2 of this Agreement.


 




    	5



    	 



    

 


(b)
If a Piggyback Registration is initiated as a primary underwritten offering on behalf of the Issuer and the managing underwriter
advises the Issuer and the holders of Registrable Securities (if any holders of Registrable Securities have elected to include
Registrable Securities in such Piggyback Registration) in writing that in its opinion the number of shares of Common Stock proposed
to be included in such registration, including all Registrable Securities and all other shares of Common Stock proposed to be
included in such underwritten offering, exceeds the number of shares of Common Stock which can be sold in such offering and/or
that the number of shares of Common Stock proposed to be included in any such registration would adversely affect the price per
share of the Common Stock to be sold in such offering, the Issuer shall include in such registration (i) first, the number of
shares of Common Stock that the Issuer proposes to sell; (ii) second, the number of shares of Common Stock requested to be included
therein by holders of Registrable Securities, allocated pro rata among all such holders on the basis of the number of Registrable
Securities owned by each such holder or in such manner as they may otherwise agree; and (iii) third, the number of shares of Common
Stock requested to be included therein by holders of Common Stock (other than holders of Registrable Securities), allocated among
such holders in such manner as they may agree; provided, that in any event the holders of Registrable Securities shall
be entitled to register at least twenty-five percent (25%) of the securities to be included in any such registration.


 


(c)
If a Piggyback Registration is initiated as an underwritten offering on behalf of a holder of Common Stock other than Registrable
Securities, and the managing underwriter advises the Issuer in writing that in its opinion the number of shares of Common Stock
proposed to be included in such registration, including all Registrable Securities and all other shares of Common Stock proposed
to be included in such underwritten offering, exceeds the number of shares of Common Stock which can be sold in such offering
and/or that the number of shares of Common Stock proposed to be included in any such registration would adversely affect the price
per share of the Common Stock to be sold in such offering, the Issuer shall include in such registration (i) first, the number
of shares of Common Stock requested to be included therein by the holder(s) requesting such registration and by the holders of
Registrable Securities, allocated pro rata among such holders on the basis of the number of shares of Common Stock (on a fully
diluted, as converted basis) and the number of Registrable Securities, as applicable, owned by all such holders or in such manner
as they may otherwise agree; and (ii) second, the number of shares of Common Stock requested to be included therein by other holders
of Common Stock, allocated among such holders in such manner as they may agree.


 


(d)
If any Piggyback Registration is initiated as a primary underwritten offering on behalf of the Issuer, the Issuer shall select
the investment banking firm or firms to act as the managing underwriter or underwriters in connection with such offering.

(b)
If on any day after the effective date of a Registration Statement, sales of all of the Registrable Securities included on such
Registration Statement cannot be made (other than during an Allowable Grace Period) pursuant to such Registration Statement or
otherwise (including, without limitation, because of the suspension of trading of the Common Stock on the securities exchange
or the over-the-counter market on which such Common Stock is then traded, a failure to keep such Registration Statement effective,
a failure to disclose such information as is necessary for sales to be made pursuant to such Registration Statement or the Registration
Statement ceases to be effective for any reason or the prospectus contained therein is not available for use for any reason),
or the Issuer fails to file with the SEC any required reports under Section 13 or 15(d) of the Exchange Act such that it is not
in compliance with Rule 144(c)(1) (or Rule 144(i)(2), if applicable) as a result of which any of the Investors are unable to sell
Registrable Securities without restriction under Rule 144 (including, without limitation, volume restrictions) then, as partial
relief for the damages to any holder by reason of any such delay in or reduction of its ability to sell the underlying shares
of Common Stock (which remedy shall not be exclusive of any other remedies available at law or in equity, including, without limitation,
specific performance or any additional obligation of to register Registrable Securities pursuant to this Agreement) (any such
event, a “Failure”), the Issuer shall pay to each holder of Registrable Securities relating to such Registration
Statement, a cash amount equal to, or, at such holder’s election if offered by the Company, warrants to purchase Common
Stock of the Issuer with a Black-Scholes value of no less than, one percent (1%) of the market value (based upon the most recent
closing price of the Common Stock on the securities exchange or over-the-counter market on which such Common Stock has been traded)
of such Investor’s Registrable Securities, on the thirtieth day after the date of a Failure and every thirtieth day thereafter
(pro-rated for periods totaling less than thirty (30) days) until such Failure is cured. Notwithstanding anything to the contrary
contained herein, (i) such payments shall cease to accrue when all of the Registrable Securities may be sold pursuant to Rule
144 without any restrictions or limitations, and (ii) in no event shall the aggregate amount of all such payments paid to an Investor
exceed an amount equal to ten percent (10%) of such Investor’s original purchase price for the Registrable Securities.

To the fullest extent permitted by law, the Issuer will, and hereby does, indemnify, hold harmless and defend each Note Holder
or transferee thereof in accordance with Section 15 (the “Investor”), the directors, officers, partners, members,
employees, agents, representatives of, and each Person, if any, who controls any Investor within the meaning of the Securities
Act or the Exchange Act (each, an “Indemnified Person”), against any losses, claims, damages, liabilities,

effective date of such Registration Statement, or contained in the final prospectus (as amended or supplemented, if the Issuer
files any amendment thereof or supplement thereto with the SEC) or the omission or alleged omission to state therein any material
fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made,
not misleading;


 


(iii)
any violation or alleged violation by the Issuer of the Securities Act, the Exchange Act, any other law, including, without limitation,
any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant
to a Registration Statement; or


 




    	11



    	 



    

 


(iv)
any violation of this Agreement (the matters in the foregoing clauses (i) through (iv) being, collectively, “Violations”).


 


Subject
to Section 7(c), the Issuer shall reimburse the Indemnified Persons, promptly as such expenses are incurred and are due and payable,
for any reasonable legal fees or other expenses incurred by them in connection with investigating or defending any such Claim.
Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 7(a): (1) shall
not apply to a Claim by an Indemnified Person arising out of or based upon a Violation which occurs in reliance upon and in conformity
with information furnished in writing to the Issuer by such Indemnified Person for such Indemnified Person expressly for use in
connection with the preparation of the Registration Statement or any such amendment thereof or supplement thereto, if such prospectus
was timely made available by the Issuer; and (2) shall not apply to amounts paid in settlement of any Claim if such settlement
is effected without the prior written consent of the Issuer, which consent shall not be unreasonably withheld or delayed. Such
indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person
and shall survive the transfer of any of the Registrable Securities by an Investor pursuant to Section 15.


 


(b)
In connection with any Registration Statement in which an Investor is participating, each such Investor agrees to severally and
not jointly indemnify, hold harmless and defend, to the same extent and in the same manner as is set forth in Section 7(a), the
Issuer, each of its directors, each of its officers who signs the Registration Statement and each Person, if any, who controls
the Issuer within the meaning of the Securities Act or the Exchange Act (each, an “Indemnified Party”), against
any Claim or Indemnified Damages to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise,
insofar as such Claim or Indemnified Damages arise out of or are based upon any Violation, in each case to the extent, and only
to the extent, that such Violation occurs in reliance upon and in conformity with written information furnished to the Issuer
by such Investor expressly for use in connection with such Registration Statement; and, subject to Section 7(c), such Investor
shall reimburse the Indemnified Party for any legal or other expenses reasonably incurred by an Indemnified Party in connection
with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 7(b)
and the agreement with respect to contribution contained in Section 7(f) shall not apply to amounts paid in settlement of any
Claim if such settlement is effected without the prior written consent of such Investor, which consent shall not be unreasonably
withheld or delayed; provided, further, however, that the Investor shall be liable under this Section 7(b) for only that amount
of a Claim or Indemnified Damages as does not exceed the net proceeds to such Investor as a result of the sale of Registrable
Securities pursuant to such Registration Statement. Such indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by an Investor pursuant
to Section 15.

(c)
Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 7 of notice of the commencement of any
action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified
Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 7, deliver to the indemnifying
party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to
the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of
the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified
Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its
own counsel with the fees and expenses of not more than one counsel for all such Indemnified Person or Indemnified Party to be
paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the Indemnified Person or Indemnified Party,
as applicable, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would
be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other
party represented by such counsel in such proceeding. In the case of an Indemnified Person, legal counsel referred to in the immediately
preceding sentence shall be selected by the Investors holding at least a majority in interest of the Registrable Securities included
in the Registration Statement to which the Claim relates. The Indemnified Party or Indemnified Person shall reasonably cooperate
with the indemnifying party in connection with any negotiation or defense of any such action or Claim by the indemnifying party
and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person
which relates to such action or Claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised
at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall
be liable for any settlement of any action, claim or proceeding effected without its prior written consent, provided, however,
that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without
the prior written consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement
or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified
Party or Indemnified Person of a release from all liability in respect to such Claim or litigation and such settlement shall not
include any admission as to fault on the part of the Indemnified Party. Following indemnification as provided for hereunder, the
indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third
parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying
party of any liability to the Indemnified Person or Indemnified Party under this Section 7, except to the extent that the indemnifying
party is prejudiced in its ability to defend such action.


 


(d)
The indemnification required by this Section 7 shall be made by periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills are received or Indemnified Damages are incurred.


 


(e)
The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified
Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject
to pursuant to the law.


 




    	13



    	 



    

 


(f)
To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make
the maximum contribution with respect to any amounts for which it would otherwise be liable under this Section 7 to the fullest
extent permitted by law; provided, however, that: (i) no Person involved in the sale of Registrable Securities which Person is
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) in connection with such sale
shall be entitled to contribution from any Person involved in such sale of Registrable Securities who was not guilty of fraudulent
misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the amount of net
proceeds received by such seller from the sale of such Registrable Securities pursuant to such Registration Statement. Notwithstanding
the provisions of this Section 7(f), no Investor shall be required to contribute, in the aggregate, any amount in excess of the
amount by which the net proceeds actually received by such Investor from the applicable sale of the Registrable Securities subject
to the Claim exceeds the amount of any damages that such Investor has otherwise been required to pay, or would otherwise be required
to pay under Section 7(b), by reason of such untrue or alleged untrue statement or omission or alleged omission.


 


8.
PARTICIPATION IN UNDERWRITTEN REGISTRATIONS 


 


No
Person may participate in any registration hereunder which is underwritten unless such Person, (a) agrees to sell such Person’s
securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve
such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements
and other documents required under the terms of such underwriting arrangements; provided, that no holder of Registrable
Securities included in any underwritten registration shall be required to make any representations or warranties to the Issuer
or the underwriters (other than representations and warranties regarding such holder, such holder’s ownership of its shares
of Common Stock to be sold in the offering and such holder’s intended method of distribution) or to undertake any indemnification
obligations to the Issuer or the underwriters with respect thereto, except as otherwise provided in Section 7.


 


9.
RULE 144 COMPLIANCE


 


With
a view to making available to the holders of Registrable Securities the benefits of Rule 144 and any other rule or regulation
of the SEC that may at any time permit a holder to sell securities of the Issuer to the public without registration or pursuant
to a registration on Form S-3 (or any successor form), the Issuer shall:


 


(a)
make and keep public information available, as those terms are understood and defined in Rule 144, at all times after the Registration
Date;


 




    	14



    	 



    

 


(b)
use reasonable best efforts to file with the SEC in a timely manner all reports and other documents required of the Issuer under
the Securities Act and the Exchange Act, at any time after the Issuer has become subject to such reporting requirements; and


 


(c)
furnish to any holder so long as the holder owns Registrable Securities, promptly upon request, a written statement by the Issuer
as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act, a copy of the
most recent annual or quarterly report of the Issuer, and such other reports and documents so filed or furnished by the Issuer
as such holder may reasonably request in connection with the sale of Registrable Securities without registration.


 


10.
PRESERVATION OF RIGHTS


 


The
Issuer shall not (a) grant any registration rights to third parties which are more favorable than or inconsistent with the rights
granted hereunder, or (b) enter into any agreement, take any action, or permit any change to occur, with respect to its securities
that violates or subordinates the rights expressly granted to the holders of Registrable Securities in this Agreement.


 


11.
TERMINATION


 


This
Agreement shall terminate and be of no further force or effect when there shall no longer be any Registrable Securities outstanding;
provided, that the provisions of Section 6 and Section 7 shall survive any such termination.


 


12.
REMEDIES


 


Each
holder of Registrable Securities, in addition to being entitled to exercise all rights granted by Law, including recovery of damages,
shall be entitled to specific performance of its rights under this Agreement. The Issuer acknowledges that monetary damages would
not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and the Issuer
hereby agrees to waive the defense in any action for specific performance that a remedy at Law would be adequate.


 


13.
NOTICES, SEVERABILITY, HEADINGS AND COUNTERPARTS


 


The
provisions of Sections 9.5, 9.8, 9.9 and 9.21 of the Notes Agreement shall apply to this Agreement mutatis mutandis.


 


14.
ENTIRE AGREEMENT


 


This
Agreement, together with the Purchase Agreements constitutes the sole and entire agreement of the Parties with respect to the
subject matter contained herein, and supersedes all prior and contemporaneous understandings and agreements, both written and
oral, with respect to such subject matter.


 




    	15



    	 



    

 


15.
SUCCESSOR AND ASSIGNS


 


This
Agreement shall be binding upon and shall inure to the benefit of the Parties and their respective successors and permitted assigns
(including to any Note Holder). Each Note Purchaser may assign its rights hereunder to any purchaser or transferee of Registrable
Securities; provided, that such purchaser or transferee shall, as a condition to the effectiveness of such assignment,
be required to execute a counterpart to this Agreement agreeing to be treated as an Note Purchaser whereupon such purchaser or
transferee shall have the benefits of, and shall be subject to the restrictions contained in, this Agreement as if such purchaser
or transferee was originally included in the definition of an Note Purchaser herein and had originally been a party hereto.


 


16.
NO THIRD-PARTY BENEFICIARIES


 


This
Agreement is for the sole benefit of the Parties and their respective successors and permitted assigns (including any Note Holders)
and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit
or remedy of any nature whatsoever, under or by reason of this Agreement.


 


17.
AMENDMENT, MODIFICATION AND WAIVER


 


Except
as otherwise provided herein, the provisions of this Agreement may only be amended, modified, supplemented or waived with the
prior written consent of the Issuer and the holders of at least seventy-five percent (75%) of the Registrable Securities. No waiver
by any Party shall operate or be construed as a waiver in respect of any failure, breach or default not expressly identified by
such written waiver, whether of a similar or different character, and whether occurring before or after that waiver. Except as
otherwise set forth in this Agreement, no failure to exercise, or delay in exercising, any right, remedy, power or privilege arising
from this Agreement shall operate or be construed as a waiver thereof; nor shall any single or partial exercise of any right,
remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy,
power or privilege.


 


18.
APPLICABLE LAW


 


THIS
AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED
AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK (INCLUDING SECTION 5-1401 OF THE GENERAL OBLIGATIONS
LAW OF THE STATE OF NEW YORK), WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES THAT WOULD RESULT IN THE APPLICATION OF THE LAWS
OF ANOTHER JURISDICTION.


 




    	16



    	 



    

 


19.
CONSENT TO JURISDICTION AND SERVICE OF PROCESS


 


ALL
JUDICIAL PROCEEDINGS BROUGHT AGAINST THE ISSUER ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER TRANSACTION DOCUMENT,
OR ANY OBLIGATIONS THEREUNDER, MAY BE BROUGHT IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK (OR ANY
STATE COURTS SITTING IN THE BOROUGH OF MANHATTAN IN THE EVENT THE SOUTHERN DISTRICT OF NEW YORK LACKS SUBJECT MATTER JURISDICTION).
BY EXECUTING AND DELIVERING THIS AGREEMENT, THE ISSUER FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, IRREVOCABLY: 


 


(i)
ACCEPTS GENERALLY AND UNCONDITIONALLY THE NON-EXCLUSIVE JURISDICTION AND VENUE OF SUCH COURTS;


 


(ii)
WAIVES ANY DEFENSE OF FORUM NON CONVENIENS;


 


(iii)
AGREES THAT SERVICE OF ALL PROCESS IN ANY SUCH PROCEEDING IN ANY SUCH COURT MAY BE MADE BY REGISTERED OR CERTIFIED MAIL, RETURN
RECEIPT REQUESTED, TO THE ISSUER, AT ITS ADDRESS PROVIDED IN ACCORDANCE WITH SECTION 13;


 


(iv)
AGREES THAT SERVICE AS PROVIDED IN CLAUSE (III) ABOVE IS SUFFICIENT TO CONFER PERSONAL JURISDICTION OVER THE ISSUER IN ANY
SUCH PROCEEDING IN ANY SUCH COURT, AND OTHERWISE CONSTITUTES EFFECTIVE AND BINDING SERVICE IN EVERY RESPECT;


 


(v)
AGREES THAT THE NOTE PURCHASERS RETAIN THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO BRING PROCEEDINGS
AGAINST THE ISSUER IN THE COURTS OF ANY OTHER JURISDICTION; AND


 


(vi)
AGREES THAT THE PROVISIONS OF THIS SECTION 19 RELATING TO JURISDICTION AND VENUE SHALL BE BINDING AND ENFORCEABLE TO THE FULLEST
EXTENT PERMISSIBLE UNDER NEW YORK GENERAL OBLIGATIONS LAW SECTION 5-1402 OR OTHERWISE.


 


20.
WAIVER OF JURY TRIAL


 


THE
PARTIES HEREBY AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT
OF THIS AGREEMENT. The scope of this waiver is intended to be all-encompassing of any and all disputes that may be filed in any
court and that relate to the subject matter of this transaction, including contract claims, tort claims, breach of duty claims
and all other common law and statutory claims. The Parties each acknowledge that this waiver is a material inducement for the
Parties to enter into a business relationship that the Parties have already relied on the waiver in entering into this Agreement
and that each will continue to rely on the waiver in their related future dealings. The Parties further warrant and represent
that each has reviewed this waiver with its legal counsel, and that each knowingly and voluntarily waives its jury trial rights
following consultation with legal counsel. THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN
WRITING, AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT. In
the event of litigation, this Agreement may be filed as a written consent to a trial by the court.
