created hereby in the Collateral.

irrevocably terminated) that: 
 (a) Authorization of the Equity Interests. The Equity Interests are duly authorized
and validly issued, are fully paid and nonassessable and are not subject to the preemptive rights of any Person. All other shares of stock, units or membership or partnership interests constituting Collateral will be duly authorized and validly
issued, fully paid and nonassessable and not subject to the preemptive rights of any Person. 
 (b) Title. The Pledgor
has good and indefeasible title to the Collateral and will at all times be the legal and beneficial owner of such Collateral free and clear of any attachments, levies, taxes, liens, security interests and encumbrances of every kind and nature
(“Liens”), except for Permitted Encumbrances. Except with respect to Permitted Encumbrances, there exists no “adverse claim” within the meaning of Section 8-102 of the Uniform Commercial Code as in effect in the State
of New York (the “UCC”) with respect to the Equity Interests. 
 (c) Exercising of Rights. To the best
of the Pledgor’s knowledge, other than as set forth on Schedule 5 hereto, the exercise by the Pledgee of its rights and remedies hereunder will not violate any law or governmental regulation or any material contractual restriction binding on or
affecting the Pledgor or any of its property.

notice or filing with any governmental authority or with the issuer of any Equity Interests is required either (i) for the pledges made by the Pledgor or for the granting of the security interests by the Pledgor pursuant to this Agreement or
(ii) to the best of the Pledgor’s knowledge, for the exercise by the Pledgee of its rights and remedies hereunder (except as may be required by laws affecting the offering and sale of securities).

and delivery of a Control Acknowledgment (as defined in Section 6(e) below) with regard to uncertificated Equity Interests consisting of membership or partnership interests will perfect and establish the first priority of the Pledgee’s
security interest, for the ratable benefit of the Creditor Parties, in the Equity Interests and, when properly perfected by filing or registration, in all other Collateral represented by such Equity Interests and instruments securing the Secured
Obligations. Except as set forth in this Section 5(e), no action is necessary to perfect or otherwise protect such security interest.

adversely affect the Collateral; 
 (g) Power and Authority. Other than as set forth on Schedule 5 hereto,the Pledgor
has the requisite power and authority to enter into this Agreement and to pledge and assign the Collateral to the Pledgee, for the ratable benefit of the Creditor Parties, in accordance with the terms of this Agreement; 
 (h) Transfer Restrictions. Other than as set forth on Schedule 5 hereto, there are no restrictions on transfer of the Equity
Interests contained in the certificate of incorporation or by-laws (or equivalent organizational documents) of the issuer or otherwise which have not otherwise been enforceably and legally waived by the necessary parties; 
 (i) Securities Laws. None of the Equity Interests has been issued or transferred in violation of the securities registration,
securities disclosure or similar laws of any jurisdiction to which such issuance or transfer may be subject; 
 (j) Grant
of Security Interest. The pledge and assignment of the Collateral and the grant of a security interest under this Agreement vest in the Pledgee, for the ratable benefit of the Creditor Parties, all rights of the Pledgor in the Collateral as
contemplated by this Agreement; and 
 (k) Equity Percentage. The Equity Interests constitute 81.51% of the issued and
outstanding units or membership interests owned by the Pledgor of such issuer as set forth on Schedule I hereto, as applicable.

 (e) Further Assurances. Promptly execute and deliver at its expense all further instruments and documents and take all further
action that may be reasonably necessary and desirable or that the Pledgee may reasonably request in order to (i) perfect and protect the security interest created hereby in the Collateral (including, without limitation, any and all action

 (f) Amendments. Not make or consent to any amendment or other modification or
waiver with respect to any of the Collateral or enter into any agreement or allow to exist any restriction with respect to any of the Collateral other than pursuant hereto, including, without limitation, any amendment that would (i) impair the

Pledgee, for the ratable benefit of the Creditor Parties, in the Collateral, including, without limitation, any amendment electing to no longer treat any membership or partnership interest as a security under Section 8-103 of the UCC, or any
election to turn any previously certificated membership or partnership interest into an uncertificated membership or partnership interest.

federal or foreign agency in connection with the ownership of the Collateral. 
 7. Advances by the Pledgee. Upon the occurrence and
during the continuance of an Event of Default, the Pledgee may, at its sole option and in its sole discretion, perform the same and in so doing may expend such sums as the Pledgee may reasonably deem advisable in the performance thereof, including,
without limitation, the payment of any insurance premiums, the payment of any taxes, a payment to obtain a release of a Lien or potential Lien (other than a Permitted Lien), expenditures made in defending against any adverse claim (other than a
Permitted Lien) and all other expenditures which the Pledgee may make for the protection of the Collateral hereof or which may be compelled to make by operation of law. All such sums and amounts so expended shall be repayable by the Pledgor promptly
upon timely notice thereof and demand therefor, shall constitute additional Secured Obligations and shall bear interest from the date said amounts are expended at the highest interest rate set forth in the PetroTech Notes. No such performance of any
covenant or agreement by the Pledgee on behalf of the Pledgor, and no such advance or expenditure therefor, shall relieve the Pledgor of any default under the terms of this Agreement or the other Documents. The Pledgee may make any payment hereby
authorized in accordance with any bill, statement or estimate procured from the appropriate public office or holder of the claim to be discharged without inquiry into the accuracy of such bill, statement or estimate or into the validity of any tax

 (a) An “Event of Default” under any Document or any agreement or note related to any Document shall have occurred

obligations under any Document or any agreement between the Pledgor and the Pledgee, including, without limitation, this Agreement, and such default shall not be cured during any applicable cure period;

agreement, statement or certificate given in writing pursuant hereto or thereto or in connection herewith or therewith shall be false or misleading in any material respect; 
 (d) Any portion of the Collateral is subjected to a levy of execution, attachment, distraint or other judicial process or any portion of
the Collateral is the subject of a claim (other than by the Pledgee) of a Lien or other right or interest in or to the Collateral and such levy or claim shall not be cured, disputed or stayed within a period of fifteen (15) business days after
the occurrence thereof; or 
 (e) The Pledgor shall (i) apply for, consent to, or suffer to exist the appointment of, or
the taking of possession by, a receiver, custodian, trustee, liquidator or other fiduciary of itself or of all or a substantial part of its property, (ii) make a general assignment for the benefit of creditors, (iii) commence a voluntary

 9. Remedies. 
 (a) General Remedies. Upon the occurrence of an Event of Default and during the continuation thereof, the Pledgee shall have, in respect of the Collateral, in addition to the rights and remedies provided herein, in the Documents or
by law, the rights and remedies of a secured party under the UCC or any other applicable law. In addition, Pledgee may exercise all corporate rights with respect to the Collateral including, without limitation, all rights of conversion, exchange,
subscription or any other rights, privileges or options pertaining to any shares of the Collateral as if it were the absolute owner thereof, including, but without limitation, the right to exchange, at its discretion, any or all of the Collateral
upon the merger, consolidation, reorganization, recapitalization or other readjustment of the issuer thereof, or upon the exercise by the issuer of any right, privilege or option pertaining to any of the Collateral, and, in connection therewith, to
deposit and deliver any and all of the Collateral with any committee, depository, transfer agent, registrar or other designated agent upon such terms and conditions as it may determine, all without liability except to account for property actually
received by it. 
 (b) Transfer and Sale of Collateral. Upon the occurrence of an Event of Default and during the
continuation thereof, without limiting the generality of this Section and without notice, the Pledgee may, in its sole discretion, sell or otherwise dispose of or realize upon the Collateral, or any part thereof, in one or more parcels, at public or
private sale, at any exchange or broker’s board or elsewhere, at such price or 

  

 8 








 
prices and on such other terms as the Pledgee may deem commercially reasonable, for cash, credit or for future delivery or otherwise in accordance with
applicable law. To the extent permitted by law, the Pledgee may in such event bid for the purchase of such securities. The Pledgor agrees that, to the extent notice of sale shall be required by law and has not been waived by the Pledgor, any
requirement of reasonable notice shall be met if notice, specifying the place of any public sale or the time after which any private sale is to be made, is personally served on or mailed, postage prepaid, to the Pledgor, in accordance with the
notice provisions of Section 11 of the Master Security Agreement at least ten (10) days before the time of such sale. The Pledgee shall not be obligated to make any sale of the Collateral regardless of notice of sale having been given. The
Pledgee may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. The Pledgor hereby waives
and releases any and all right or equity of redemption, whether before or after sale hereunder. At any such sale, unless prohibited by applicable law, the Pledgee may bid for and purchase the whole or any part of the Collateral so sold free from any
such right or equity of redemption. All moneys received by the Pledgee hereunder, whether upon sale of the Collateral or any part thereof or otherwise, shall be held by the Pledgee and applied by it as provided in Sections 9(e) and 14 hereof. No
failure or delay on the part of the Pledgee in exercising any rights hereunder shall operate as a waiver of any such rights nor shall any single or partial exercise of any such rights preclude any other or future exercise thereof or the exercise of
any other rights hereunder. The Pledgee shall have no duty as to the collection or protection of the Collateral or any income thereon nor any duty as to preservation of any rights pertaining thereto, except to apply the funds in accordance with the
requirements of Sections 9(e) and 14 hereof. The Pledgee may exercise its rights with respect to property held hereunder without resort to other security for or sources of reimbursement for the Secured Obligations. In addition to the foregoing,
Pledgee shall have all of the rights, remedies and privileges of a secured party under the UCC regardless of the jurisdiction in which enforcement hereof is sought. 
 (c) Private Sale. The Pledgor recognizes that the Pledgee may be unable to effect (or to do so only after delay which would
adversely affect the value that might be realized from the Collateral) or may deem it impracticable to effect a public sale of all or any part of the Equity Interests or any of the securities constituting the Collateral and that the Pledgee may,
therefore, determine to make one or more private sales of any such securities to a restricted group of purchasers who will be obligated to agree, among other things, to acquire such securities for their own account, for investment and not with a
view to the distribution or resale thereof. The Pledgor acknowledges that any such private sale may be at prices and on terms less favorable to the seller than the prices and other terms which might have been obtained at a public sale and,
notwithstanding the foregoing, agrees that such private sale shall be deemed to have been made in a commercially reasonable manner and that the Pledgee shall have no obligation to delay sale of any such securities for the period of time necessary to
permit the issuer of such securities to register such securities for public sale under the Securities Act of 1933, as amended. The Pledgor further acknowledges and agrees that any offer to sell such securities which has been made privately in the
manner described above shall be deemed to involve a “public sale” under the UCC, notwithstanding that such sale may not constitute a “public offering” under the Securities Act of 1933, as amended, and the Pledgee may, in such
event, bid for the purchase of such securities. 
  

 9 








 (d) Retention of Collateral. In addition to the rights and remedies hereunder,
upon the occurrence and during the continuance of an Event of Default, the Pledgee may, after providing the notices required by Section 9-620 of the UCC or otherwise complying with the requirements of applicable law of the relevant
jurisdiction, retain all or any portion of the Collateral in satisfaction of the Secured Obligations. Unless and until the Pledgee shall have provided such notices, however, the Pledgee shall not be deemed to have retained the Collateral in
satisfaction of any Secured Obligations for any reason. 
 (e) Deficiency. In the event that the proceeds of any sale,
collection or realization are insufficient to pay all amounts to which the Pledgee is legally entitled, the Pledgor shall be liable for the deficiency, together with interest thereon at the highest interest rate set forth in the PetroTech Notes,
together with the costs of collection and the reasonable fees of any attorneys employed by the Pledgee to collect such deficiency. Any surplus remaining after the full payment and satisfaction of the Secured Obligations shall be returned to the
Pledgor, or to whomsoever a court of competent jurisdiction shall determine to be entitled thereto. 
 10. Waiver of Marshaling. The
Pledgor hereby waives any right to compel any marshaling of any of the Collateral. 
 11. No Waiver. Any and all of the Pledgee’s
rights with respect to the Liens granted under this Agreement shall continue unimpaired, and Pledgor shall be and remain obligated in accordance with the terms hereof, notwithstanding (a) the bankruptcy, insolvency or reorganization of the
Pledgor, (b) the release or substitution of any item of the Collateral at any time, or of any rights or interests therein, or (c) any delay, extension of time, renewal, compromise or other indulgence granted by the Pledgee in reference to
any of the Secured Obligations. The Pledgor hereby waives all notice of any such delay, extension, release, substitution, renewal, compromise or other indulgence, and hereby consents to be bound hereby as fully and effectively as if such Pledgor had
expressly agreed thereto in advance. No delay or extension of time by the Pledgee in exercising any power of sale, option or other right or remedy hereunder, and no failure by the Pledgee to give notice or make demand, shall constitute a waiver
thereof, or limit, impair or prejudice the Pledgee’s right to take any action against the Pledgor or to exercise any other power of sale, option or any other right or remedy. 
 12. Expenses. The Collateral shall secure, and the Pledgor shall pay to the Pledgee on demand, from time to time, all reasonable costs and
expenses (including but not limited to, reasonable attorneys’ fees and costs, taxes, and all transfer, recording, filing and other charges) of, or incidental to, the custody, care, transfer, administration of the Collateral or any other
collateral, or in any way relating to the enforcement, protection or preservation of the rights or remedies of the Pledgee under this Agreement or with respect to any of the Secured Obligations.

Default:

this Agreement, and shall not be liable for any failure to do so or any delay in doing so. The Pledgee shall not be liable for any act or omission or for any error of judgment or any mistake of fact or law in its individual capacity or its capacity
as attorney-in-fact except acts or omissions resulting from its gross negligence or willful misconduct. This power of attorney is conferred on the Pledgee solely to protect, preserve and realize upon its security interest, for the ratable benefit of
the Creditor Parties, in Collateral. 
 (b) Performance by the Pledgee of the Pledgor’s Obligations. If the
Pledgor fails to perform any agreement or obligation contained herein, the Pledgee itself may perform, or cause performance of, such agreement or obligation, and the expenses of the Pledgee incurred in connection therewith shall be payable by the
Pledgor pursuant to Section 7 hereof. 
 (c) Assignment by the Pledgee. The Pledgee may from time to time assign
the Secured Obligations and any portion thereof and/or the Collateral and any portion thereof, and the assignee shall be entitled to all of the rights and remedies of the Pledgee under this Agreement in relation thereto. 
 (d) The Pledgee’s Duty of Care. Other than the exercise of reasonable care to assure the safe custody of the Collateral while
being held by the Pledgee hereunder, the Pledgee shall have no duty or liability to preserve rights pertaining thereto, it being understood and agreed that the Pledgor shall be responsible for preservation of all rights in the Collateral, and the
Pledgee shall be relieved of all responsibility for the Collateral upon surrendering it or tendering the surrender of it to the Pledgor. The Pledgee shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral
in its possession if such Collateral is accorded treatment substantially equal to that which the Pledgee accords its own property, which shall be no less than the treatment employed by a reasonable and prudent Person in the industry, it being
understood that the Pledgee shall not have responsibility for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to any Collateral, whether or not the Pledgee has or is
deemed to have knowledge of such matters; or (ii) taking any necessary steps to preserve rights against any parties with respect to any Collateral. 
  

 12 








 (e) Voting Rights in Respect of the Collateral. 
 (i) So long as no Event of Default shall have occurred and be continuing, to the extent permitted by law, the Pledgor may exercise any and
all voting and other consensual rights pertaining to the Collateral or any part thereof for any purpose not inconsistent with the terms of this Agreement or any Document; and 
 (ii) Upon the occurrence and during the continuance of an Event of Default, all rights of the Pledgor to exercise the voting and other
consensual rights which they would otherwise be entitled to exercise pursuant to clause (i) of this subsection (e) shall cease and all such rights shall thereupon become vested in the Pledgee which shall then have the sole right to
exercise such voting and other consensual rights. 
 (f) Dividend Rights in Respect of the Collateral. 
 (i) So long as no Event of Default shall have occurred and be continuing and subject to Section 4(b) hereof, the Pledgor may receive
and retain any and all dividends and other distributions (other than dividends and other distributions constituting Collateral which are addressed hereinabove) or interest paid in respect of the Collateral to the extent they are allowed under the
Documents. 
 (ii) Upon the occurrence and during the continuance of an Event of Default: 
 (A) all rights of the Pledgor to receive the dividends, other distributions and interest payments which it would otherwise be authorized
to receive and retain pursuant to paragraph (i) of this subsection shall cease and all such rights shall thereupon be vested in the Pledgee which shall then have the sole right to receive and hold such dividends, other distributions and
interest payments as Collateral; and 
 (B) all dividends and interest payments which are received by the Pledgor contrary to
the provisions of paragraph (A) of this clause shall be received in trust for the benefit of the Creditor Parties, shall be segregated from other property or funds of the Pledgor and shall be forthwith paid over to the Pledgee as Collateral in
the exact form received, to be held by the Pledgee as Collateral and as further collateral security for the Secured Obligations. 
  

 13 








 (g) Release of Collateral. The Pledgee may release any of the Collateral from this
Agreement or may substitute any of the Collateral for other Collateral without altering, varying or diminishing in any way the force, effect, lien, pledge or security interest of this Agreement as to any Collateral not expressly released or
substituted, and this Agreement shall continue as a first priority lien on all Collateral not expressly released or substituted. 
 14.
Application of Proceeds. Upon the occurrence of and during the continuance of an Event of Default, any payments in respect of the Secured Obligations and any proceeds of any Collateral, when received by the Pledgee in cash or its equivalent,
will be applied as follows: first, to all reasonable costs and expenses of the Pledgee (including, without limitation, reasonable attorneys’ fees and expenses) incurred in connection with the implementation and/or enforcement of this
Agreement and/or any of the other Documents; second, to the principal amount of the Secured Obligations; third, to such of the Secured Obligations consisting of accrued but unpaid interest and fees; fourth, to all other amounts
payable with respect to the Secured Obligations; and fifth, to the payment of the surplus, if any, to whoever may be lawfully entitled to receive such surplus. The Pledgor shall remain liable to the Pledgee for any deficiency. 
 15. Costs of Counsel. If at any time hereafter, whether upon the occurrence of an Event of Default or not, the Pledgee employs counsel to prepare
or consider amendments, waivers or consents with respect to this Agreement, or to take action or make a response in or with respect to any legal or arbitral proceeding relating to this Agreement or relating to the Collateral, or to protect the
Collateral or exercise any rights or remedies under this Agreement or with respect to the Collateral, then the Pledgor agrees to promptly pay upon demand any and all such reasonable documented costs and expenses incurred by the Pledgee, all of which
costs and expenses shall constitute Secured Obligations hereunder. 
 16. Continuing Agreement. 
 (a) This Agreement shall be a continuing agreement in every respect and shall remain in full force and effect so long as any Document is
in effect or any amounts payable thereunder shall remain outstanding. 
 (b) This Agreement shall continue to be effective or
be automatically reinstated, as the case may be, if at any time payment, in whole or in part, of any of the Secured Obligations is rescinded or must otherwise be restored or returned by the Pledgee as a preference, fraudulent conveyance or otherwise
under any bankruptcy, insolvency or similar law, all as though such payment had not been made; provided that in the event payment of all or any part of the Secured Obligations is rescinded or must be restored or returned, all reasonable costs
and expenses (including, without limitation, any reasonable legal fees and disbursements) incurred by the Pledgee in defending and enforcing such reinstatement shall be deemed to be included as a part of the Secured Obligations. 
 17. Amendments; Waivers; Modifications. This Agreement and the provisions hereof may not be amended, waived, modified, changed, discharged or
terminated except in accordance with the terms of the Documents. 
  

 14 








 18. Successors in Interest. This Agreement shall create a continuing security interest in the
Collateral and shall be binding upon the Pledgor, its successors and assigns and shall inure, together with the rights and remedies of the Pledgee hereunder, to the Pledgee for the ratable benefit of the Creditor Parties and their successors and
permitted assigns; provided, however, that the Pledgor may not assign its rights or delegate its duties hereunder without the prior written consent of the Pledgee. To the fullest extent permitted by law, the Pledgor hereby releases the
Pledgee, and its successors and permitted assigns, from any liability for any act or omission relating to this Agreement or the Collateral. 
 19. Notices. All notices required or permitted to be given under this Agreement shall be in conformance with Section 11 of the Master Security Agreement. 
 20. Counterparts. This Agreement may be executed in any number of counterparts, each of which where so executed and delivered shall be an
original, but all of which shall constitute one and the same instrument. It shall not be necessary in making proof of this Agreement to produce or account for more than one such counterpart. 
 21. Headings. The headings of the sections and subsections hereof are provided for convenience only and shall not in any way affect the meaning or
construction of any provision of this Agreement. 
 22. Governing Law; Consent to Jurisdiction and Service of Process; Waiver of Jury
Trial; Joinder. 
 (a) THIS AGREEMENT AND THE OTHER DOCUMENTS SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED IN SUCH STATE, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. 
 (b) THE PLEDGOR HEREBY CONSENTS AND AGREES THAT THE STATE OR FEDERAL COURTS LOCATED IN THE COUNTY OF NEW YORK, STATE OF NEW YORK SHALL
HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN THE PLEDGOR, ON THE ONE HAND, AND THE PLEDGEE AND/OR ANY OTHER CREDITOR PARTY, ON THE OTHER HAND, PERTAINING TO THIS AGREEMENT OR ANY OF THE OTHER DOCUMENTS OR TO ANY
MATTER ARISING OUT OF OR RELATED TO THIS AGREEMENT OR ANY OF THE OTHER DOCUMENTS, PROVIDED, THAT THE PLEDGOR ACKNOWLEDGES THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF THE COUNTY OF NEW YORK, STATE OF NEW
YORK; AND FURTHER PROVIDED, THAT NOTHING IN THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO PRECLUDE THE PLEDGEE OR ANY OTHER CREDITOR PARTY FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO COLLECT THE INDEBTEDNESS, TO
REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY FOR THE INDEBTEDNESS, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER 

  

 15 








 
IN FAVOR OF THE PLEDGEE. THE PLEDGOR EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND
THE PLEDGOR HEREBY WAIVES ANY OBJECTION WHICH IT MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS. THE PLEDGOR HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH
ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH SUMMONS, COMPLAINT AND OTHER PROCESS MAY BE MADE BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO SUCH PLEDGOR AT THE ADDRESS SET FORTH IN THE MASTER SECURITY AGREEMENT AND THAT SERVICE SO MADE SHALL BE
DEEMED COMPLETED UPON THE EARLIER OF SUCH PLEDGOR’S ACTUAL RECEIPT THEREOF OR THREE (3) DAYS AFTER DEPOSIT IN THE U.S. MAILS, PROPER POSTAGE PREPAID. 
 (c) THE PARTIES HERETO DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST
COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, WHETHER ARISING IN CONTRACT, TORT, OR OTHERWISE BETWEEN
THE PLEDGEE AND/OR ANY OTHER CREDITOR PARTY, AND/OR THE PLEDGOR ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEN IN CONNECTION WITH THIS AGREEMENT, ANY OTHER DOCUMENT OR THE TRANSACTIONS RELATED
HERETO OR THERETO. 
 (d) It is understood and agreed that any person or entity that desires to become a Pledgor hereunder, or
is required to execute a counterpart of this Agreement after the date hereof pursuant to the requirements of any Document, shall become a Pledgor hereunder by (i) executing a Joinder Agreement in form and substance satisfactory to the Pledgee,
(ii) delivering supplements to such exhibits and annexes to such Documents as the Pledgee shall reasonably request and/or set forth in such joinder agreement and (iii) taking all actions as specified in this Agreement as would have been
taken by such Pledgor had it been an original party to this Agreement, in each case with all documents required above to be delivered to the Pledgee and with all documents and actions required above to be taken to the reasonable satisfaction of the
Pledgee. 
 23. Severability. If any provision of this Agreement is determined to be illegal, invalid or unenforceable, such provision
shall be fully severable and the remaining provisions shall remain in full force and effect and shall be construed without giving effect to the illegal, invalid or unenforceable provisions. 
 24. Entirety. This Agreement and the other Documents represent the entire agreement of the parties hereto and thereto, and supersede all prior
agreements and understandings, oral or written, if any, including any commitment letters or correspondence relating to the Documents or the transactions contemplated herein and therein. 
  

 16 








 25. Survival. All representations and warranties of the Pledgor hereunder shall survive the
execution and delivery of this Agreement and the other Documents. 
 26. Other Security. To the extent that any of the Secured
Obligations are now or hereafter secured by property other than the Collateral (including, without limitation, real and other personal property owned by the Pledgor), or by a guarantee, endorsement or property of any other Person, then the Pledgee
shall have the right to proceed against such other property, guarantee or endorsement upon the occurrence and during the continuance of any Event of Default, and the Pledgee has the right, in its sole discretion, to determine which rights, security,
liens, security interests or remedies the Pledgee, for the ratable benefit of the Creditor Parties, shall at any time pursue, relinquish, subordinate, modify or take with respect thereto, without in any way modifying or affecting any of them or any
of the Pledgee’s rights or the Secured Obligations under this Agreement or under any other of the Documents.
