Section
6.10 Sale of Pledged Equity Interests in Connection with Enforcement. If at any time when the Secured Party shall
determine to exercise its right to sell all or any part of the Pledged Equity Interests pursuant to Section 7.01, such Pledged
Equity Interests or the part thereof to be sold shall not, for any reason whatsoever, be effectively registered under the Securities
Act, the Secured Party may, in its sole and absolute discretion and to the fullest extent permitted by applicable law now or hereafter
in effect, sell such Pledged Equity Interests or part thereof by private sale in such manner and under such circumstances as the
Secured Party may deem necessary or advisable in order that such sale may legally be effected without such registration, provided
that at least ten days’ notice of the time and place of any such sale shall be given to the Borrower. Without limiting the
generality of the foregoing, in any such event the Secured Party, in its sole and absolute discretion, (a) may proceed to make
such private sale notwithstanding that a registration statement for the purpose of registering such Pledged Equity Interests or
part thereof shall have been filed under such Securities Act, (b) may approach and negotiate with a single possible purchaser
to effect such sale and (c) may restrict such sale to a purchaser who will represent and agree that such purchaser is purchasing
for its own account, for investment, and not with a view to the distribution or sale of such Pledged Equity Interests or part
thereof. In the event of any such sale, the Secured Party shall incur no responsibility or liability to the Borrower for selling
all or any part of the Pledged Equity Interests at a price which the Secured Party may in good faith deem reasonable under the
circumstances, notwithstanding the possibility that a substantially higher price might be realized if the sale were deferred until
the registration as aforesaid.

UPON OCCURRENCE OF EVENT OF DEFAULT

 

Section
7.01 Remedies Generally. The Borrower agrees that, if any Event of Default shall have occurred and be continuing, then
and in every such case, subject to any mandatory requirements of applicable law then in effect, the Secured Party, in addition
to any rights now or hereafter existing under applicable law, shall have all rights as a secured creditor under the UCC in all
relevant jurisdictions and may exercise any or all of the following rights (all of which the Borrower hereby agrees is commercially
reasonable to the fullest extent permitted under applicable law now or hereafter in effect):

 

(a)
personally, or by agents’ attorneys or other authorized representatives, immediately retake possession of the Collateral
or any part thereof from the Borrower or any other Person who then has possession of any part thereof with or without notice or
process of law, and for that purpose may enter upon the Borrower’s or such other Person’s premises where any of the
Collateral is located and remove the same;

 

(b)
sell, assign or otherwise liquidate, or direct the Borrower to sell, assign or otherwise liquidate, any or all of the Collateral
or any part thereof, and take possession of the proceeds of any such sale or liquidation;

 

(c)
issue a Notice of Exclusive Control with respect to any or all of the Collateral Accounts and issue entitlement orders or instructions
with respect thereto;

 

(d)
withdraw any or all securities and/or instruments in any Controlled Securities Account for application to the Secured Obligations
in accordance with Section 7.05 hereof;

 

(e)

    	 	- 11 -	 

    	 		 

    

 

(f)
pay, perform or satisfy, or cause to be paid, performed or satisfied, for the benefit of the Borrower, any of the obligations,
terms, covenants, provisions or conditions to be paid, observed, performed or satisfied by the Borrower under any contract, agreement
or instrument relating to its Collateral, all in accordance with the terms, covenants, provisions and conditions thereof, as and
to the extent that the Borrower fails or refuses to perform or satisfy the same;

 

(g)
enter into any extension of, or any other agreement in any way relating to, any of the Collateral;

 

(h)
make any compromise or settlement the Secured Party deems desirable or necessary with respect to any of the Collateral; and/or

 

(i)

Section
7.02 Disposition of the Collateral. Upon the occurrence and continuance of an Event of Default, any Collateral repossessed
by the Secured Party under or pursuant to Section 7.01 and any other Collateral whether or not so repossessed by the Secured Party,
may be sold, assigned, leased or otherwise disposed of under one or more contracts or as an entirety, and without the necessity
of gathering at the place of sale of the property to be sold, and in general in such manner, at such time or times, at such place
or places and on such terms as the Secured Party may, in compliance with any mandatory requirements of applicable law, determine
to be commercially reasonable. Any of the Collateral may be sold, leased or otherwise disposed of, in the condition in which the
same existed when taken by the Secured Party or after any overhaul or repair which the Secured Party shall determine to be commercially
reasonable. Except in the case of any Collateral that is perishable or threatens to decline speedily in value or is of a type
customarily sold on a recognized market, (i) in the case of any such disposition which shall be a private sale or other private
proceedings permitted by such requirements, such sale shall be made upon not less than ten days’ written notice to the Borrower
specifying the time at which such disposition is to be made and the intended sale price or other consideration therefor, and shall
be subject, for the ten days after the giving of such notice, to the right of the Borrower or any nominee of the Borrower to acquire
the Collateral involved at a price or for such other consideration at least equal to the intended sale price or other consideration
so specified, and (ii) in the case of any such disposition which shall be a public sale permitted by such requirements, such sale
shall be made upon not less than ten days’ written notice to the Borrower specifying the time and place of such sale and,
in the absence of applicable requirements of law, shall be by public auction (which may, at the Secured Party’s sole option,
be subject to reserve), after publication of notice of such auction not less than ten days prior thereto in two newspapers in
general circulation in the city where such Collateral is located. To the extent permitted by any such requirement of law, the
Secured Party may bid for and become the purchaser (by bidding in Secured Obligations or otherwise) of the Collateral or any item
thereof offered for sale in accordance with this Section without accountability to the Borrower (except to the extent of surplus
money received as provided in Section 7.05). Unless so obligated under mandatory requirements of applicable law, the Secured Party
shall not be required to make disposition of the Collateral within a period of time which does not permit the giving of notice
to the Borrower as hereinabove specified. The Secured Party need give the Borrower only such notice of disposition as the Secured
Party shall deem to be reasonably practicable in view of such mandatory requirements of applicable law.

 

Section
7.03 Grant of License to Use Intellectual Property. For the purpose of enabling the Secured Party to exercise rights
and remedies under this Article VII at such time as the Secured Party shall be lawfully entitled to exercise such rights and remedies
and for no other purpose, the Borrower hereby grants to the Secured Party an irrevocable, non-exclusive license (exercisable without
payment of royalty or other compensation to the Borrower) to use, assign or sublicense any of the Intellectual Property of the
Borrower, now owned or hereafter acquired by the Borrower, and wherever the same may be located, including in such license reasonable
access to all media in which any of the licensed items may be recorded or stored and to all computer programs used for the compilation
or printout thereof.

Section
7.04 Waiver of Claims. Except as otherwise provided in this Agreement, THE BORROWER HEREBY WAIVES, TO THE EXTENT
PERMITTED BY APPLICABLE LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE SECURED PARTY’S TAKING POSSESSION OR THE
SECURED PARTY’S DISPOSITION OF ANY OF THE COLLATERAL, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING
FOR ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH THE BORROWER WOULD OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY
STATUTE OF THE UNITED STATES OR OF ANY STATE, and the Borrower hereby further waives, to the extent permitted by law: (i) all
damages occasioned by such taking of possession except any damages which are the direct result of the Secured Party’s gross
negligence or willful misconduct; (ii) all other requirements as to the time, place and terms of sale or other requirements with
respect to the enforcement of the Secured Party’s rights hereunder; and (iii) all rights of redemption, appraisement, valuation,
stay, extension or moratorium now or hereafter in force under any applicable law in order to prevent or delay the enforcement
of this Agreement or the absolute sale of the Collateral or any portion thereof, and the Borrower, for itself and all who may
claim under it, insofar as it or they now or hereafter lawfully may, hereby waives the benefit of all such laws to the fullest
extent permitted by applicable law now or hereafter in effect. Any sale of, or the grant of options to purchase, or any other
realization upon, any Collateral shall operate to divest all right, title, interest, claim and demand, either at law or in equity,
of the Borrower therein and thereto, and shall be a perpetual bar both at law and in equity against the Borrower and against any
and all Persons claiming or attempting to claim the Collateral so sold, optioned or realized upon, or any part thereof, from,
through and under the Borrower.

 

Section
7.05 Application of Proceeds. All Collateral and proceeds of Collateral obtained and realized by the Secured Party
in connection with the enforcement of this Agreement pursuant to this Article VII shall be applied as follows:

 

(i)
first, to the payment to the Secured Party, for application to the Secured Obligations in such order as the Secured Party
determines in its sole discretion; and

 

(ii)
second, to the extent remaining after the application pursuant to the preceding clause (i) and following the termination
of this Agreement, to the Borrower or to whomever may be lawfully entitled to receive such payment.

 

Section
7.06 Remedies Cumulative. Each and every right, power and remedy hereby specifically given to the Secured Party
shall be in addition to every other right, power and remedy specifically given under this Agreement or the other Loan Documents
or now or hereafter existing at law or in equity, or by statute, and each and every right, power and remedy whether specifically
herein given or otherwise existing may be exercised from time to time or simultaneously and as often and in such order as may
be deemed expedient by the Secured Party. All such rights, powers and remedies shall be cumulative and the exercise or the beginning
of exercise of one shall not be deemed a waiver of the right to exercise any other or others. No delay or omission of the Secured
Party in the exercise of any such right, power or remedy, or partial or single exercise thereof, and no renewal or extension of
any of the Secured Obligations, shall impair or constitute a waiver of any such right, power or remedy or shall be construed to
be a waiver of any Event of Default or an acquiescence therein. No notice to or demand on the Borrower in any case shall entitle
it to any other or further notice or demand in similar or other circumstances or constitute a waiver of any of the rights of the
Secured Party to any other or further action in any circumstances without notice or demand. In the event that the Secured Party
shall bring any suit to enforce any of its rights hereunder and shall be entitled to judgment, then in such suit the Secured Party
may recover reasonable, actual expenses, including attorneys’ fees, and the amounts thereof shall be included in such judgment.

 

    	 	- 13 -	 

    	 		 

    

 

Section
7.07 Discontinuance of Proceedings. In case the Secured Party shall have instituted any proceeding to enforce any
right, power or remedy under this Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall have been discontinued
or abandoned for any reason or shall have been determined adversely to the Secured Party, then and in every such case the Borrower,
the Secured Party and each holder of any of the Secured Obligations shall be restored to their former positions and rights hereunder
with respect to the Collateral subject to the security interest created under this Agreement, and all rights, remedies and powers
of the Secured Party shall continue as if no such proceeding had been instituted.

 

Section
7.08 Purchasers of Collateral. Upon any sale of any of the Collateral by the Secured Party hereunder (whether by virtue
of the power of sale herein granted, pursuant to judicial process or otherwise), the receipt of the Secured Party or the officer
making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold, and such purchaser or
purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Secured Party or
such officer or be answerable in any way for the misapplication or nonapplication thereof.

    	Page 22 of 37	Equity Exchange Agreement

    	 		 

    

 

6.2

the Rhino Group and its respective Representatives (other than any such Representative that is also a Representative of Holdings)
(collectively, the “Rhino Related Parties”) against, and hold each of them harmless from, any and all Losses
that may be suffered, sustained or incurred by any Rhino Related Party or asserted against any Rhino Related Party as a result

warranties of Holdings contained herein or in any of the Transaction Documents or (ii) the breach of any covenant or agreement
of Holdings contained herein or in the Transaction Documents; provided, however, that such claim for indemnification

a Rhino Related Party has given notice (stating in reasonable detail, to the extent known, the basis of the claim for indemnification)
to Holdings shall constitute the date upon which such claim has been made).

 

6.3
Indemnification Procedure.

 

(a)
Promptly after any Holdings Related Party or any Rhino Related Party (hereafter, the “Indemnified Party”) discovers
facts giving rise to a claim for indemnification hereunder, including receipt by it of notice of any indemnifiable claim hereunder,
or the commencement of any action, suit or proceeding by a third Person (a “Third Party Claim”), which the
Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the
indemnifying party hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of
such action, suit or proceeding. Failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any
liability it may have to such Indemnified Party hereunder except to the extent (and then only to the extent) that the Indemnifying
Party can demonstrate that the Indemnifying Party’s rights and obligations pursuant to this Section VI are materially
and actually prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known
and shall include a formal demand for indemnification under this Agreement. The Indemnifying Party shall have the right to defend
and settle any such matter, at its own expense and by its own counsel; provided, however, that the Indemnifying Party (i) promptly
notifies the Indemnified Party of its intention to do so and acknowledges its indemnification obligations pursuant to this Section
VI in writing to the Indemnified Party and (ii) pursues such defense (or, if applicable, settlement) diligently and in good
faith. If the Indemnifying Party undertakes to defend or settle such claim, the Indemnified Party shall cooperate with the Indemnifying
Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation
shall include furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying
Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the sole
cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake
to defend or settle any such matter, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying
Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or
settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (x) at its expense, to
participate in the defense of such matter and the negotiations of the settlement thereof and (y) if (i) the Indemnifying Party
has failed to assume the defense and employ counsel within 30 days of when the Indemnified Party has provided written notice of
such claim for indemnification or fails to diligently and in good faith pursue the defense thereof or (ii) if counsel to the Indemnified
Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or
in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed
to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate
counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees
of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred.

 

    	Page 23 of 37	Equity Exchange Agreement

    	 		 

    

 

(b)
Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim or otherwise
enter into any final conclusion with respect to such claim without the prior written consent of the Indemnified Party (i) if the
settlement thereof (A) imposes any Liability or obligation on, (B) does not include a complete and unconditional release from
Liability of or (C) contains any admission of wrongdoing by, the Indemnified Party or (ii) that subjects the Indemnified Party
to any non-monetary or other equitable relief or criminal liability or imposes any other obligation on or requires any payment
from the Indemnified Party.

 

6.4
Limitations and Other Indemnity Claim Matters.

 

(a)
No Indemnifying Party shall have any obligation to indemnify any Indemnified Party against, or reimburse any Indemnified Party
for, any Loss or series of related Losses pursuant to Section 6.1(i), with respect to Rhino (other than the representation
and warranties contained in Sections 5.1, 5.2, 5.3, 5.4, 5.10, 5.18, 5.20 and
5.21) or pursuant to Section 6.2(i), with respect to Holdings until (i) each such individual Loss exceeds $20,000
and (ii) the aggregate amount of all such Losses exceeds $100,000, in which event the Indemnifying Party shall be liable for all
such Losses from the first dollar.

 

(b)
Notwithstanding anything herein to the contrary, in no event shall (i) the Rhino Group be liable to any Holdings Related Party
for any Loss or series of related Losses pursuant to Section 6.1(i) in excess of $1,000,000 or (ii) Holdings be liable
to any Rhino Related Party for any Loss or series of related Losses pursuant to Section 6.2(i) in excess of $1,000,000,
as applicable.

 

(c)
For purposes of the indemnification obligations contained in this Section VI, when determining whether a breach or inaccuracy
of any representation, warranty or covenant has occurred, and when calculating the amount of Losses incurred arising out of or
relating to any such breach or inaccuracy, all references to “material”, “materially”, “materiality”
or “material adverse effect” or similar or correlative terms shall be disregarded.

Transaction Documents.

10.3
Further Assurances. The parties agree (a) to furnish upon request to each other such further information, (b) to execute
and deliver to each other such other documents, and (c) to do such other acts and things, all as the other party may reasonably
request for the purpose of carrying out the intent of this Agreement and the documents referred to in this Agreement.

 

10.4
Waiver. The rights and remedies of the parties to this Agreement are cumulative and not alternative. Neither the failure
nor any delay by any party in exercising any right, power, or privilege under this Agreement or the documents referred to in this
Agreement will operate as a waiver of such right, power, or privilege, and no single or partial exercise of any such right, power,
or privilege will preclude any other or further exercise of such right, power, or privilege or the exercise of any other right,
power, or privilege. To the maximum extent permitted by Applicable Laws, (a) no claim or right arising out of this Agreement or
the documents referred to in this Agreement can be discharged by one party, in whole or in part, by a waiver or renunciation of
the claim or right unless in writing signed by the other party; (b) no waiver that may be given by a party will be applicable
except in the specific instance for which it is given; and (c) no notice to or demand on one party will be deemed to be a waiver
of any obligation of such party or of the right of the party giving such notice or demand to take further action without notice
or demand as provided in this Agreement or the documents referred to in this Agreement.

 

10.5
Entire Agreement and Modification. This Agreement supersedes all prior agreements between the parties with respect to its
subject matter and constitutes (along with the documents referred to in this Agreement) a complete and exclusive statement of
the terms of the agreement between the parties with respect to its subject matter. This Agreement may not be amended except by
a written agreement executed by the party against whom the enforcement of such amendment is sought.

 

10.6
Assignments, Successors, and No Third-Party Rights. No party may assign any of its rights under this Agreement without
the prior written consent of the other parties. Subject to the preceding sentence, this Agreement will apply to, be binding in
all respects upon, and inure to the benefit of and be enforceable by the respective successors and permitted assigns of the parties.
Except as otherwise provided for herein, nothing expressed or referred to in this Agreement will be construed to give any Person
other than the parties to this Agreement any legal or equitable right, remedy, or claim under or with respect to this Agreement
or any provision of this Agreement. This Agreement and all of its provisions and conditions are for the sole and exclusive benefit
of the parties to this Agreement and their successors and assigns.

10.7
Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction,
the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement held invalid or unenforceable
only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable. Upon such determination
that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good
faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent
permitted by Applicable Law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the
extent possible.

 

10.8
Section Headings, Construction. (a) When a reference is made in this Agreement to a Section or Schedule, such reference
shall be to a Section of or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained
in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.
Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall
be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and
“hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not
to any particular provision of this Agreement. All terms defined in this Agreement shall have the defined meanings when used in
any certificate or other document made or delivered pursuant hereto unless otherwise defined therein. The definitions contained
in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to
the feminine and neuter genders of such term. Any agreement, instrument or statute defined or referred to herein or in any agreement
or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, modified or
supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession
of comparable successor statutes and references to all attachments thereto and instruments incorporated therein. References to
a Person are also to its permitted successors and assigns.

 

10.9
Governing Law; Submission to Jurisdiction; Waiver of Jury Trial.

 

(a)
This Agreement will be governed by the laws of the State of Delaware without regard to conflicts of laws principles.

 

(b)
ANY LEGAL SUIT, ACTION OR PROCEEDING ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE OTHER TRANSACTION DOCUMENTS OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY MAY BE INSTITUTED IN THE FEDERAL COURTS OF THE UNITED STATES OF AMERICA OR THE COURTS OF THE STATE
OF DELAWARE, AND EACH PARTY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF SUCH COURTS IN ANY SUCH SUIT, ACTION OR PROCEEDING.
SERVICE OF PROCESS, SUMMONS, NOTICE OR OTHER DOCUMENT BY MAIL TO SUCH PARTY’S ADDRESS SET FORTH HEREIN SHALL BE EFFECTIVE
SERVICE OF PROCESS FOR ANY SUIT, ACTION OR OTHER PROCEEDING BROUGHT IN ANY SUCH COURT. THE PARTIES IRREVOCABLY AND UNCONDITIONALLY
WAIVE ANY OBJECTION TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR ANY PROCEEDING IN SUCH COURTS AND IRREVOCABLY WAIVE AND AGREE
NOT TO PLEAD OR CLAIM IN ANY SUCH COURT THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN
AN INCONVENIENT FORUM.

(c)
EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT OR THE OTHER TRANSACTION DOCUMENTS
IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY
RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER TRANSACTION
DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (A)
NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE
THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION, (B) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) SUCH PARTY
MAKES THIS WAIVER VOLUNTARILY, AND (D) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.9(c).

 

10.10
Specific Performance. The parties agree that irreparable damage would occur if any provision of this Agreement were not
performed in accordance with the terms hereof and that the parties shall be entitled to specific performance of the terms hereof,
in addition to any other remedy to which they are entitled at law or in equity.

 

10.11
Legal Representation. The parties hereto acknowledge that Holdings has selected Thompson & Knight LLP and Rhino and
Rhino GP have selected other counsel as their respective legal counsel in connection with the preparation of this Agreement. Each
party acknowledges that such respective counsel of Holdings and Rhino has not represented such party in connection with the preparation
and negotiation of this Agreement, and such counsel shall owe no duties directly to any such party. Each party confirms that such
party has been advised to consult with such party’s own legal, financial and tax advisors regarding the implications of
this transaction and has been afforded the opportunity to consult with advisors that such party deems advisable in connection
with the negotiations and execution of this Agreement.

 

10.12
Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original
copy of this Agreement and all of which, when taken together, will be deemed to constitute one and the same agreement. A signed
copy of this Agreement delivered by facsimile, e-mail or other means of electronic transmission shall be deemed to have the same
legal effect as delivery of an original signed copy of this Agreement.
