(h) Each Debtor will promptly (and in any event, within five (5) Business Days of any such event) notify the Agent, in writing, of any event which materially affects the value of the Collateral or the ability of the Debtors to dispose of the Collateral, including, but not limited to, the levy of any legal process against any Collateral and the adoption of any marketing order, arrangement or procedure affecting the Collateral, whether governmental or otherwise.

(i) Each Debtor shall pay all costs necessary to preserve, defend, enforce and, to the extent practical, collect, the Collateral, including but not limited to taxes, assessments, insurance premiums, repairs, rent, storage costs and expenses of sales and any costs to perfect the security interest of the Agent and Creditors (collectively, the “Collateral Costs”). Without waiving such Debtor’s Event of Default (if any) for failure to make any such payment, the Agent, following any such failure, at its option may pay any such Collateral Costs, and discharge encumbrances on the Collateral (other than Permitted Liens), and such Collateral Costs payments shall be a part of the Indebtedness and bear interest at the rate set out in the Debentures. Each Debtor agrees to reimburse the Agent and Creditors on demand for any Collateral Costs reasonably incurred.

(j) Until the Agent or Creditors exercise their rights to make collection, the Debtors will use their commercially reasonable efforts to diligently collect all Collateral consisting of accounts receivables consistent with their customary business practices.

(k) If any Collateral is or becomes the subject of any registration certificate, certificate of deposit or negotiable document of title, including any warehouse receipt or bill of lading, each Debtor shall promptly and in any event within five (5) Business Days of such Debtor’s receipt thereof (or such later time as the Agent may agree in its sole discretion) deliver such document to the Agent on behalf of the Creditors, together with any necessary endorsements.

(l) The Debtors will not sell, lease, agree to sell or lease, or otherwise dispose of any Collateral (each, a “Disposition”) except for (A) Dispositions consisting of leases of equipment or sales of inventory in the ordinary course of business or any Permitted Charter, (B) Dispositions in the ordinary course of business of obsolete or worn out Collateral with a fair market value not to exceed $1,000,000 in the aggregate per calendar year, (C) Dispositions of Collateral with a fair market value not to exceed $500,000 in the aggregate per calendar year and (D) Dispositions not prohibited by the Debentures.

(m) Each Debtor will maintain and keep in force commercial risk insurance (i) covering the customary risks for the business that the Debtors are engaged in, (ii) insuring the Collateral against loss by fire, flood and wind and such other hazards as are customary in the area where such Collateral is located and (iii) naming the Agent and its successors or assigns as their interests may appear as loss payee (in the case of property insurance) and an additional insured (in the case of liability insurance), and the Debtors will maintain insurance of similar types and coverages as maintained on the date hereof and consistent with past practice, with financially sound and reputable insurance companies and associations acceptable to the Agent based on the Agent’s reasonable judgment (or as to workers’ compensation or similar insurance, in an insurance fund or by self-insurance authorized by the jurisdiction in which its operations are carried on). Notwithstanding anything to the contrary set forth herein, the Debtors (i) represent and warrant that as of the date hereof, the Company is insured under all of the insurance policies of Nauticus Sub, and (ii) agree that the Company shall at all times be insured under all of the insurance policies of Nauticus Sub and each other direct and/or indirect subsidiary of the Company. On or before the date that is five (5) Business Days following the date hereof (or such other later date to which Agent may agree to in writing in its sole and absolute discretion), the Debtors shall deliver to Agent certificates of insurance evidencing that the required insurance is in force, together with satisfactory additional insured or lender loss payee, as the case may be, endorsements, each in form and substance satisfactory to the Agent in its sole discretion. Upon the request of the Agent, from time to time, the Debtors shall deliver to the Agent a copy of each insurance policy required to be maintained hereunder together with certificates of insurance evidencing that the required insurance is in force, together with satisfactory additional insured or lender loss payee, as the case may be, endorsements, each in form and substance satisfactory to the Agent in its sole discretion.

(n) The Debtors will not attach any Collateral to any real property or fixture in a manner which might cause such Collateral to become a part thereof unless the Debtor first obtains the written consent of any owner, holder of any lien on the real property or fixture, or other Person having an interest in such property to the removal by the Agent of the Collateral from such real property or fixture; provided that this paragraph (n) shall not prohibit any Debtor from acquiring or owning real property. Such written consent shall be in form and substance acceptable to the Agent and shall provide that the Agent have no liability to such owner, holder of any lien, or any other Person.

(o) As of the date hereof, the Perfection Certificate includes a complete list of all patents, trademark and service mark registrations, copyright registrations, mask work registrations, and all applications therefore, in which each Debtor has any right, title, or interest, throughout the world. Each Debtor will promptly notify the Agent of any acquisition (by adoption and use, purchase, license or otherwise) of any patent, trademark or service mark registration, copyright registration, mask work registration, and applications therefore, and unregistered trademarks and service marks and copyrights, throughout the world, which are granted or filed or acquired by any Debtor after the date hereof or which are not listed on the Perfection Certificate.

(p) Each Debtor will at its expense, use its commercially reasonable efforts to diligently prosecute all patent, trademark or service mark or copyright applications pending on or after the date hereof that it deems appropriate in its business judgment, will maintain in effect all issued patents and will renew all trademark and service mark registrations, including payment of any and all maintenance and renewal fees relating thereto, except for such patents, service marks and trademarks that are being sold, donated or abandoned by the Debtors pursuant to the terms of its intellectual property management program. Each Debtor also will promptly make application on any patentable but unpatented inventions, registerable but unregistered trademarks and service marks, and copyrightable but uncopyrighted works that it deems appropriate in its business judgment. Each Debtor will at its expense protect and defend all rights in the Collateral against any material claims and demands of all Persons other than the Agent and Creditors or the holders of Permitted Liens and will, at its expense, enforce all rights in the Collateral against any and all infringers of the Collateral where such infringement would materially impair the value or use of the Collateral to the Debtors or the Creditors. No Debtor will license or transfer any of the Collateral constituting patents, trademarks, service marks, or copyright applications, except for such licenses or transfers as are customary in the ordinary course of the Debtors’ business, or except with the prior written consent of the Agent, which consent shall not be unreasonably withheld.

(q) The Equity Interests owned by the Debtors as of the date hereof (i) are not dealt in or traded on securities exchanges or in securities markets, (ii) do not constitute investment company securities and (iii) are not held by any Person in an investment account, securities account, commodity account or other similar account as the date hereof, except as disclosed in Schedule III-1 hereto.

(r) If any Debtor forms or acquires any new direct or indirect subsidiary (other than an Excluded Subsidiary), the Debtors agree to, concurrently with the acquisition or formation thereof, (i) amend this Agreement to reflect the addition of such Equity Interests and pledge the applicable Equity Interests to Agent as additional Collateral in accordance with Section 5, (ii) cause such newly formed or acquired subsidiary to become a party to this Agreement as a Debtor pursuant to a joinder in form satisfactory to Agent for the purposes of granting a security interest in such subsidiary’s assets as additional Collateral, (iii) deliver to Agent an opinion of counsel in form and substance acceptable to Agent, addressing, among other things, the due authorization, due execution and delivery and enforceability of the foregoing documents with respect to such subsidiary and (iv) to execute or deliver such other agreements, documents requested by the Agent in connection therewith.

(s) Subject to the Foreign Collateral Exclusion, if any Debtor forms or acquires any Direct Foreign Subsidiary that is an Excluded Subsidiary, the Debtors agree to, concurrently with the acquisition or formation thereof, (i) amend this Agreement to reflect the addition of the applicable Equity Interests and pledge the applicable Equity Interests to Agent as additional Collateral in accordance with Section 5 and the last paragraph of Section 1, and (ii) take such other actions as Agent deems necessary or reasonably advisable to perfect the Agent’s security interest therein, including without limitation, executing and/or delivering to Agent foreign law pledge agreements and such other documents requested by the Agent in connection therewith together with opinions of counsel to the Debtors and/or the applicable Excluded Subsidiary (including foreign counsel, if applicable) in form and substance reasonably acceptable to Agent, addressing, among other things, the due authorization, due execution and delivery and enforceability of the foregoing documents with respect to the pledge of the Equity Interest in such Direct Foreign Subsidiary that is an Excluded Subsidiary. If any existing Excluded Subsidiary ceases to be an Excluded Subsidiary for any reason (including without limitation by operation of a change in applicable law) then, the Debtors agree to, within ten (10) Business Days (or such longer period as may be agreed to by the Agent in its reasonable discretion) after such existing Excluded Subsidiary ceases to be an Excluded Subsidiary, (i) amend this Agreement to reflect the pledge of the additional Equity Interests not pledged prior to such time due to the operation of the Foreign Collateral Exclusion (such that 100% of the Equity Interests held by the Debtors shall then be pledged to Agent as Collateral, in accordance with Section 5), (ii) cause such former Excluded Subsidiary become a party to this Agreement pursuant to a joinder in form satisfactory to Agent for the purposes of granting a security interest in such former Excluded Subsidiary’s assets as additional Collateral, (iii) deliver to Agent opinions of counsel to the Debtors and/or the applicable Excluded Subsidiary (including foreign counsel, if applicable) form and substance acceptable to Agent, addressing, among other things, the due authorization, due execution and delivery and enforceability of the foregoing documents with respect to such former Excluded Subsidiary and (iv) to execute or deliver such other agreements, documents reasonably requested by the Agent in connection therewith. Subject to the Foreign Collateral Exclusion, the Debtors shall promptly, and in any event no later than the date that is forty-five (45) days following the date hereof (or such other later date to which Agent may agree to in writing in its reasonable discretion), take such actions as Agent deems necessary or reasonably advisable to perfect the Agent’s security interest in the applicable Equity Interests owned by a Debtor in any Excluded Subsidiary that is a Direct Foreign Subsidiary existing as of the date hereof, as set forth on Schedule I and Schedule IV-2 hereto, including without limitation, executing and/or delivering to Agent foreign law pledge agreements and such other documents requested by the Agent in connection therewith together with opinions of counsel to the Debtors and/or the applicable Excluded Subsidiary (including foreign counsel, if applicable) in form and substance reasonably acceptable to Agent, addressing, among other things, the due authorization, due execution and delivery and enforceability of the foregoing documents with respect to the pledge of the Equity Interest in such Direct Foreign Subsidiary that is an Excluded Subsidiary.

(t) If any Debtor enters into or becomes a party to any Pre-Delivery Contract or MOA, concurrently with becoming a party thereto, it shall execute and deliver Pre-delivery Security and such other documents, and provide such other evidence satisfactory to the Agent, in order to assign to the Agent for the benefit of the Creditors all of its right, title and interest in such Pre-Delivery Contract or MOA in a form acceptable to the Agent, together with such consents to such assignments from counterparties thereto as the Agent may reasonably require.

(u) Each Debtor makes the representations, warranties and covenants set out in Exhibit D hereto to the Agent and each other Creditor in respect any Collateral Ship. In the event of any conflict between the provisions of this Section 8 and the provisions of Exhibit D, the provisions of Exhibit D shall prevail as it relates to any Collateral Ship.

(v) The Debtors agree that the Debtors and the Foreign Subsidiaries shall, and shall cause each of their respective subsidiaries to, use commercially reasonable efforts to (i) exclude from any potential commercial contract or other agreement to be entered into with any customer of any Debtor, Foreign Subsidiary or any subsidiary of a Debtor or Foreign Subsidiary any provision that a change of control of any Debtor, or of any of such Debtor’s direct or indirect subsidiaries, gives rise to a right to terminate such agreement or other contract, and (ii) exclude from any potential employment agreement or any other contract for the performance of services by any employee or other individual any provision that a change of control of any Debtor, or of any of such Debtor’s direct or indirect subsidiaries, gives rise to a right to terminate such agreement or other contract.

(w) The Debtors agree that (i) no intellectual property of any Debtor shall be sold, assigned, or otherwise transferred to any Excluded Subsidiary, (ii) and that no intellectual property shall be owned, acquired or held in the name of an Excluded Subsidiary; provided that, to the extent that any intellectual property is hereafter developed by a Excluded Subsidiary, the Debtors shall, promptly, and in any event within five (5) Business Days following the date such intellectual property is developed by such Excluded Subsidiary (or such other later date to which Agent may agree to in writing in its sole and absolute discretion), notify the Agent in writing and cause such intellectual property to be assigned to a Debtor hereunder to be pledged as additional Collateral of such Debtor hereunder, delivering any documents requested by the Agent to evidence such assignment, in form and substance satisfactory to the Agent.

(x)

(i) The Debtors agree that, without the prior written consent of Agent (which consent shall not be unreasonably withheld, conditioned, or delayed), the Excluded Subsidiaries shall not own any Collateral Ships (including any AUVs), except that the consolidated Excluded Subsidiaries, shall be permitted to own collectively, without the prior written consent of Agent, up to five (5) Collateral Ships consisting of not more that two (2) “Hydronauts” and not more than three (3) “Aquanauts”, in each case, which will not be subject to a lien in favor of the Agent for so long as any such Collateral Ship is owned by an Excluded Subsidiary (the “Collateral Ship Limit”); provided that, for the avoidance of doubt, the Collateral Ship Limit is a limit on the total number of Collateral Ships permitted to be owned collectively by the consolidated Excluded Subsidiaries considered as a whole, without the prior written consent of the Agent, at any time.

(ii) If at any time, any Excluded Subsidiary (1) in order to satisfy a requirement by any potential or existing customer of any Debtor or any Excluded Subsidiary to permit such Debtor or Excluded Subsidiary to secure a potential contract with such customer (a “Customer Requirement”) or (2) in order to comply with applicable law in connection with satisfying any such Customer Requirement (or to otherwise perform services required to be performed under any potential or existing customer contract), such Excluded Subsidiary, in either case, is required to own a Collateral Ship that would, when added to the total amount of Collateral Ships then owned by the collective Excluded Subsidiaries without the prior consent of the Agent, cause the total number of Collateral Ships owned by the collective Excluded Subsidiaries to exceed the Collateral Ship Limit (any such Collateral Ship, an “Excess Ship”), the Debtors may, in addition to seeking consent of the Agent as set forth in paragraph (ii) above, seek the consent of the Agent for such Excluded Subsidiary to own such Excess Ship, and such consent of the Agent shall be deemed granted, as applicable, pursuant to clause (iii) below.

(iii) The Company shall provide reasonable notice to the Agent prior to entry by any Debtor or Excluded Subsidiary into any contract containing a Customer Requirement requiring any Excluded Subsidiary to own any Excess Ship or a Customer Requirement that would require any Excluded Subsidiary to own any Excess Ship in order for such Excluded Subsidiary to comply with applicable law as result of such Customer Requirement, and shall provide Agent (1) prior to entry into any such contract a current draft copy of such proposed contract and (2) a certificate executed by an officer of the Company certifying that the conditions set forth in clause (1) or clause (2) of Section 8(x)(ii) are applicable (i.e. that the failure of such Excluded Subsidiary to own such Excess Ship would result in failure to secure the applicable potential customer contract or a breach of applicable law in complying with a Customer Requirement contained in such potential customer contract). Upon receipt by the Agent of the items set forth in clauses (1) and (2) of the foregoing sentence, the Agent shall be deemed to have consented to the applicable Excluded Subsidiary owning such Excess Ship.

(iv) Notwithstanding anything set forth to the contrary set forth herein, the Debtors and the Excluded Subsidiaries shall use commercially reasonable efforts in negotiating with potential customers to exclude Customer Requirements requiring any Excluded Subsidiary to own any Excess Ship and Customer Requirements that would require any Excluded Subsidiary to own any Excess Ship in order for such Excluded Subsidiary to comply with applicable law as result of such Customer Requirement.

(y) Without limiting the foregoing, no Foreign Subsidiary shall, and no Debtor shall permit and Subsidiary to, create or permit to subsist any mortgage, charge, pledge, lien or other encumbrance upon any or all of its present or future assets to secure any present or future indebtedness for borrowed money without the prior written consent of the Agent.

(a) Enforce the security interest given hereunder pursuant to the UCC and any other applicable law and exercise with reference to the Collateral any or all of the rights and remedies of a secured party under the UCC and as otherwise granted herein or under any other applicable law, including, without limitation, the right and power to sell, at public or private sale or sales, or otherwise dispose of, or otherwise utilize the Collateral and any part or parts thereof in any manner authorized or permitted under the UCC or any other applicable law after the occurrence and during the continuation of an Event of Default debtor, and to apply the proceeds in accordance with Section 14 hereof. To the extent permitted by law, the Debtors expressly waive any notice of sale or other disposition of the Collateral and all other rights or remedies of the Debtors or formalities prescribed by law relative to sale or disposition of the Collateral or exercise of any other right or remedy of Agent existing after the occurrence and during the continuation of an Event of Default; and to the extent any such notice is required and cannot be waived, the Debtors agree that if such notice is given in the manner provided in Section 17 hereof at least five (5) days before the time of the sale or disposition, such notice shall be deemed reasonable and shall fully satisfy any requirement for giving of said notice. Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Agent may adjourn any public or private sale.

(b) Require the Debtors to obtain the Agent’s prior written consent to any sale, lease, agreement to sell or lease, or other disposition of any Collateral consisting of inventory.

(c) Require the Debtors to segregate all collections and proceeds of the Collateral so that they are capable of identification and deliver daily such collections and proceeds to the Agent on behalf of the Creditors in kind.

(g) Demand and collect any payments on and proceeds of the Collateral. In connection therewith, each Debtor irrevocably authorizes the Agent to endorse or sign each Debtor’s name on all checks, drafts, collections, receipts and other documents, and to take possession of and open the mail addressed to such Debtor and remove therefrom any payments and proceeds of the Collateral.

(h) Grant extensions and compromise or settle claims with respect to the Collateral for less than face value, all without prior notice to any Debtor.

(i) Use or transfer any of the Debtors’ rights and interests in any Intellectual Property now owned or hereafter acquired by any Debtor, if the Agent deems such use or transfer necessary or advisable in order to take possession of, hold, preserve, process, assemble, prepare for sale or lease, market for sale or lease, sell or lease, or otherwise dispose of, any Collateral. The Debtors agree that any such use or transfer shall be without any additional consideration to any Debtor. As used in this paragraph, “Intellectual Property” includes, but is not limited to, all trade secrets, computer software, service marks, trademarks, trade names, trade styles, copyrights, patents, applications for any of the foregoing, customer lists, working drawings, instructional manuals, and rights in processes for technical manufacturing, packaging and labeling, in which any Debtor has any right or interest, whether by ownership, license, contract or otherwise.

The appointment of Agent as attorney-in-fact is coupled with an interest and shall be irrevocable until the termination of this Agreement.

(l) Exercise any other remedies available to the Agent and/or the Creditors at law or in equity.

13 SPECIAL PROVISIONS. Each of the Debtors hereby acknowledges that the sale by Agent of any Pledged Interests resulting from an exercise by Agent of its rights hereunder must, if the Securities Act is applicable to the Pledged Interests, be made in compliance with the Securities Act of 1933 (the “Securities Act”), as well as any applicable Blue Sky or other state or provincial securities laws that may impose limitations as to the manner in which Agent or any other Person may dispose of securities. Each of the Debtors acknowledges that any sale or disposition contemplated pursuant hereto may be at prices and on terms less favorable to Agent than those obtainable through a public sale without any applicable restrictions, and, notwithstanding such circumstances, each of the Debtors agrees that any such sale or other disposition shall be deemed to have been made in a commercially reasonable manner. Agent shall have no obligation to engage in public sales and no obligation to delay the sale of any Collateral for any period of time; and each of the Debtors waives any claims against Agent arising by reason of the fact that the price that might have been obtainable in a public sale was greater than the price obtained in any such sale or disposition pursuant hereto, even if Agent accepts the first offer received and does not offer the Collateral to more than one offeree.

14 APPLICATION OF PROCEEDS. In the event Agent sells or otherwise disposes of the Collateral in the course of exercising the remedies provided for in this Agreement, any amounts held, realized or received by Agent pursuant to the provisions hereof, including the proceeds of the sale of any of the Collateral or any part thereof, shall be applied by Agent first toward the payment of any costs and expenses incurred by Agent in enforcing this Agreement, in realizing on or protecting any Collateral and in enforcing or collecting any Secured Obligations or any guaranty thereof, including, without limitation, the actual attorneys’ fees and expenses incurred by Agent, all of which costs and expenses the Debtors agree to pay, and then to such other Secured Obligations in such order as Agent may elect. Any amounts and any Collateral remaining after such application and after payment to Agent on behalf of Creditors of satisfaction of all of the Secured Obligations in full, shall be paid or delivered to the Debtors, their successor or assigns, or as a court of competent jurisdiction may direct.

15 ENVIRONMENTAL MATTERS.

(a) Each Debtor represents and warrants: (i) it is not in any material violation of any health, safety, or environmental law or regulation regarding Hazardous Substances and (ii) it is not the subject of any material claim, proceeding, notice, or other communication regarding Hazardous Substances. As used herein, “Hazardous Substances” means any substance, material or waste that is or becomes designated or regulated as “toxic,” “hazardous,” “pollutant,” or “contaminant” or a similar designation or regulation under any current or future federal, state or local law (whether under common law, statute, regulation or otherwise) or judicial or administrative interpretation of such, including without limitation petroleum or natural gas.

(b) Each Debtor shall deliver to the Agent, promptly upon receipt, copies of all notices, orders, or other communications regarding (i) any enforcement action by any governmental authority relating to health, safety, the environment, or any Hazardous Substances with regard to the Debtors’ property, activities, or operations, or (ii) any claim against the Debtors regarding Hazardous Substances.

(c) The Agent and its agents and representatives will have the right at any reasonable time, after giving reasonable notice to the Debtors, to enter and visit any locations where the Collateral is located for the purposes of observing the Collateral, taking and removing environmental samples, and conducting tests. The Debtors shall reimburse the Agent on demand for the costs of any such environmental investigation and testing. The Agent will make reasonable efforts during any site visit, observation or testing conducted pursuant to this paragraph to avoid interfering with the Debtors’ use of the Collateral. The Agent is under no duty to observe the Collateral or to conduct tests, and any such acts by the Agent will be solely for the purposes of protecting the Creditors’ security and preserving the Creditors’ rights under this Agreement.

To the extent practical, the Agent shall request instructions from the Creditors with respect to any material act or action (including failure to act) in connection with the Agreement, and shall be entitled to act or refrain from acting in accordance with the instructions of Creditors holding a majority in principal amount of Debentures (based on then-outstanding principal amounts of Debentures at the time of any such determination) (a “Majority in Interest”); if such instructions are not provided despite the Agent’s request therefor, the Agent shall be entitled to refrain from such act or taking such action, and if such action is taken, shall be entitled to appropriate indemnification from the Creditors in respect of actions to be taken by the Agent; and the Agent shall not incur liability to any Person by reason of so refraining. Without limiting the foregoing, (a) no Creditor shall have any right of action whatsoever against the Agent as a result of the Agent acting or refraining from acting hereunder in accordance with the terms of the Agreement, and the Debtors shall have no right to question or challenge the authority of, or the instructions given to, the Agent pursuant to the foregoing and (b) the Agent shall not be required to take any action which the Agent believes (i) could reasonably be expected to expose it to personal liability or (ii) is contrary to this Agreement or applicable law.

5. Reliance. The Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, statement, certificate, telex, teletype or telecopier message, cablegram, radiogram, order or other document or telephone message signed, sent or made by the proper Person, and, with respect to all legal matters pertaining to the Agreement and its duties thereunder, upon advice of counsel selected by it and upon all other matters pertaining to the Agreement and its duties thereunder, upon advice of other experts selected by it. Anything to the contrary notwithstanding, the Agent shall have no obligation whatsoever to any Creditor to assure that the Collateral exists or is owned by the Debtors or is cared for, protected or insured or that the liens granted pursuant to the Agreement have been properly or sufficiently or lawfully created, perfected, or enforced or are entitled to any particular priority.

6. Indemnification. To the extent that the Agent is not reimbursed and indemnified by the Debtors, the Creditors will jointly and severally reimburse and indemnify the Agent, in proportion to their initially purchased respective principal amounts of Debentures, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against the Agent in performing its duties hereunder or under the Agreement, or in any way relating to or arising out of the Agreement except for those determined by a final judgment (not subject to further appeal) of a court of competent jurisdiction to have resulted solely from the Agent’s own gross negligence or willful misconduct. Prior to taking any action hereunder as Agent, the Agent may require each Creditor to deposit with it sufficient sums as it determines in good faith is necessary to protect the Agent for costs and expenses associated with taking such action.

7. Resignation by the Agent.

(a) The Agent may resign from the performance of all its functions and duties under the Agreement at any time by giving 30 days’ prior written notice (as provided in the Agreement) to the Debtors and the Creditors. Such resignation shall take effect upon the appointment of a successor Agent pursuant to clauses (b) and (c) below.

(b) Upon any such notice of resignation, the Creditors, acting by a Majority in Interest, shall appoint a successor Agent hereunder.

(c) If a successor Agent shall not have been so appointed within said 30-day period, the Agent shall then appoint a successor Agent who shall serve as Agent until such time, if any, as the Creditors appoint a successor Agent as provided above. If a successor Agent has not been appointed within such 30-day period, the Agent may petition any court of competent jurisdiction or may interplead the Debtors and the Creditors in a proceeding for the appointment of a successor Agent, and all fees, including, but not limited to, extraordinary fees associated with the filing of interpleader and expenses associated therewith, shall be payable by the Debtors on demand.

8. Rights with respect to Collateral. Each Creditor agrees with all other Creditors and the Agent (i) that it shall not, and shall not attempt to, exercise any rights with respect to its security interest in the Collateral, whether pursuant to any other agreement or otherwise (other than pursuant to the Agreement), or take or institute any action against the Agent or any of the other Creditors in respect of the Collateral or its rights hereunder (other than any such action arising from the breach of this Agreement) and (ii) that such Creditor has no other rights with respect to the Collateral other than as set forth in this Agreement.

9. Treatment of Funds. To the extent Agent receives any funds either from the Debtors directly on account of the Secured Obligations or as proceeds of Collateral, Agent shall retain such funds in trust for the benefit of the Creditors and shall immediately remit the same to the Creditors in proportion to the principal amount of Debentures then held by the Creditors.
