No Grantor shall create or maintain any Pledged Account without the prior written consent of the Collateral Agent (in its sole and absolute discretion) and complying with the terms of this Agreement.

(B) If at any time after the Closing Date, the average daily balance of any Account that is not subject to a Controlled Account Agreement exceeds $10,000 during any calendar month (including the calendar month in which the Closing Date occurs), the Company shall, either (x) within two (2) Business Days following such date, transfer to a Controlled Account an amount sufficient to reduce the total aggregate amount of the cash in such Account to an amount not in excess of $10,000 or (y) within twenty-one (21) calendar days following the last day of such calendar month, deliver to the Collateral Agent a Controlled Account Agreement with respect to such Account, duly executed by such Grantor and the depositary bank in which such Account is maintained.

I Without limiting any of the foregoing, if at any time on or after the date that is twenty-one (21) calendar days following the Closing Date, the total aggregate amount of the cash of the Company and any of its Subsidiaries, in the aggregate, that is not held in a Controlled Account exceeds $50,000 (the “Maximum Free Cash Amount”), the Company shall within two (2) Business Days following such date, either (x) transfer to a Controlled Account an amount sufficient to reduce the total aggregate amount of the cash that is not held in a Controlled Account to an amount not in excess of the Maximum Free Cash Amount or (y) deliver to the Collateral Agent a Controlled Account Agreement with respect to such Account (or Accounts), duly executed by such Grantor and the depositary bank in which such Account (or Accounts) is maintained, as necessary to reduce the total aggregate amount of the cash that is not held in a Controlled Account to an amount not in excess of the Maximum Free Cash Amount.

(f) Inspection and Reporting. At any time after an Event of Default has occurred and is continuing, each Grantor shall permit the Collateral Agent, or any agent or representatives thereof or such attorneys, accountant or other professionals or other Persons as the Collateral Agent may designate (at Grantors’ sole cost and expense) (i) to examine and make copies of and abstracts from any Grantor’s Records and books of account, (ii) to visit and inspect its properties, (iii) to verify materials, leases, Instruments, Accounts, Inventory and other assets of any Grantor from time to time, and (iv) to conduct audits, physical counts, appraisals, valuations and/or examinations at the locations of any Grantor.

(g) Future Subsidiaries. If any Grantor hereafter creates or acquires any Subsidiary, simultaneously with the creation or acquisition of such Subsidiary, such Grantor shall (i) if such Subsidiary is a material Subsidiary and a Domestic Subsidiary, cause such Subsidiary to become a party to this Agreement as an additional “Grantor” hereunder, (ii) deliver to the Collateral Agent updated Schedules to this Agreement, as appropriate (including, without limitation, an updated Schedule IV to reflect the grant by such Grantor of a Lien on and security interest in all Pledged Debt and Pledged Equity now or hereafter owned by such Grantor), (iii) deliver to the Collateral Agent the stock certificates representing all of the Capital Stock of such Subsidiary, along with undated stock powers for each such certificates, executed in blank (or, if any such shares of Capital Stock are uncertificated, confirmation and evidence reasonably satisfactory to the Collateral Agent that the security interest in such uncertificated securities has been transferred to and perfected by the Collateral Agent, in accordance with Sections 8-313, 8-321 and 9-115 of the Code or any other similar or local or foreign law that may be applicable), and (iv) duly execute and/or cause to be delivered to the Collateral Agent, in form and substance acceptable to the Collateral Agent, such opinions of counsel and other documents as the Collateral Agent shall request with respect thereto; provided, however, that no Grantor shall be required to pledge any Excluded Collateral and in no event shall Lucid Diagnostics or any of its Subsidiaries be required to become a Grantor hereunder. The Grantors agree that the pledge of the shares of Capital Stock acquired by a Grantor of Foreign Subsidiary may be supplemented by one or more separate pledge agreements, deeds of pledge, share charges, or other similar agreements or instruments, executed and delivered by the relevant Grantor in favor of the Collateral Agent, which pledge agreements will provide for the pledge of such shares of Capital Stock in accordance with the laws of the applicable foreign jurisdiction. With respect to such shares of Capital Stock, the Collateral Agent may, at any time and from time to time, in its sole discretion, take actions in such foreign jurisdictions that will result in the perfection of the Lien created in such shares of Capital Stock.

(h) Protection of Intellectual Property By Grantors. Each of the Grantors, at its own expenses, shall use commercially reasonable efforts to undertake the following with respect to each item of Intellectual Property used or useful to the conduct of the business of such Grantor: (i) Pay all renewal fees and other fees and costs associated with maintaining and prosecuting issuances, registrations and applications relating to such Intellectual Property and take all other customary and reasonably necessary steps to maintain each registration of such Intellectual Property. (ii) Take all actions reasonably necessary to prevent any of such Intellectual Property from becoming forfeited, abandoned, dedicated to the public (other than at the expiration of any non-renewable statutory term), or invalidated. (iii) Take any and all action that the Grantors reasonably deem appropriate under the circumstances to protect such Intellectual Property from infringement, misappropriation or dilution, including, without limitation, the prosecution and defense of infringement actions. Notwithstanding the foregoing, so long as no Event of Default has occurred and is continuing, and no Material Adverse Effect would result therefrom, no Grantor shall have any obligation to take any of the actions described in this Section 5(h) with respect to any Intellectual Property (i) that relates solely to any of the Grantor’s products or services that have been discontinued, abandoned or terminated, or (ii) that has been replaced with Intellectual Property substantially similar to the Intellectual Property that may be abandoned or otherwise become invalid.

Section 7. Additional Provisions Concerning the Collateral.

(a) To the maximum extent permitted by applicable law, and for the purpose of taking any action that the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Agreement, each Grantor hereby (i) authorizes the Collateral Agent to execute any such agreements, instruments or other documents in such Grantor’s name and to file such agreements, instruments or other documents in such Grantor’s name and in any appropriate filing office, (ii) authorizes the Collateral Agent at any time and from time to time to file, one or more financing or continuation statements, and amendments thereto, relating to the Collateral (including, without limitation, any such financing statements that (A) describe the Collateral as “all assets” or “all personal property” (or words of similar effect) or that describe or identify the Collateral by type or in any other manner as the Collateral Agent may determine regardless of whether any particular asset of such Grantor falls within the scope of Article 9 of the Code or whether any particular asset of such Grantor constitutes part of the Collateral, and (B) contain any other information required by Part 5 of Article 9 of the Code for the sufficiency or filing office acceptance of any financing statement, continuation statement or amendment, including, without limitation, whether such Grantor is an organization, the type of organization and any organizational identification number issued to such Grantor) and (iii) ratifies such authorization to the extent that the Collateral Agent has filed any such financing or continuation statements, or amendments thereto, prior to the date hereof. A photocopy or other reproduction of this Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law.

(b) After an Event of Default has occurred and for so long as such Event of Default is continuing, each Grantor hereby irrevocably appoints the Collateral Agent as its attorney-in-fact and proxy, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, from time to time in the Collateral Agent’s discretion, to take any action and to execute any instrument which the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Agreement, including, without limitation, (i) to ask, demand, collect, sue for, recover, compound, receive and give acquittance and receipts for moneys due and to become due under or in respect of any Collateral, (ii) to receive, endorse, and collect any drafts or other Instruments, Documents and Chattel Paper in connection with clause (i) above, (iii) to file any claims or take any action or institute any action, suit or proceedings which the Collateral Agent may deem necessary or desirable for the collection of any Collateral or otherwise to enforce the rights of the Collateral Agent and the Noteholders with respect to any Collateral, (iv) to execute assignments, licenses and other documents to enforce the rights of the Collateral Agent and the Noteholders with respect to any Collateral, and (v) to verify any and all information with respect to any and all Accounts. This power is coupled with an interest and is irrevocable until all of the Obligations are fully performed and Paid in Full.

(c) If any Grantor fails to perform any agreement or obligation contained herein, the Collateral Agent may itself perform, or cause performance of, such agreement or obligation, in the name of such Grantor or the Collateral Agent, and the reasonable expenses of the Collateral Agent incurred in connection therewith shall be payable by such Grantor pursuant to Section 9 hereof and such obligation shall be secured by the Collateral.

(d) The powers conferred on the Collateral Agent hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Collateral Agent shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral.

(e) As long as no Event of Default shall have occurred and be continuing and, other than in the case of a Bankruptcy Event of Default, until written notice shall be given to the applicable Grantor:

(i) Each Grantor shall have the right, from time to time, to vote and give consents with respect to the Pledged Equity, or any part thereof for all purposes not inconsistent with the provisions of this Agreement, the Securities Purchase Agreement or any other Transaction Document.

(f) (i) Each Grantor shall be entitled, from time to time, to collect and receive for its own use all: (A) cash dividends and interest paid in respect of the Pledged Equity to the extent not in violation of the Securities Purchase Agreement; (B) dividends and interest paid or payable other than in cash in respect of any Pledged Equity, and instruments and other property received, receivable or otherwise distributed in respect of, or in exchange for, any Pledged Equity; (C) dividends and other distributions paid or payable in cash in respect of any Pledged Equity in connection with a partial or total liquidation or dissolution or in connection with a reduction of capital, capital surplus or paid-in capital of a Pledged Entity; and (D) cash paid, payable or otherwise distributed, in respect of principal of, or in redemption of, or in exchange for, any Pledged Equity; provided, however, that until actually paid all rights to such distributions shall remain subject to the Lien created by this Agreement; and

(ii) all dividends and interest (other than such cash dividends and interest as are permitted to be paid to any Grantor in accordance with clause (i) above) and all other distributions in respect of any of the Pledged Equity, whenever paid or made, shall be delivered to the Collateral Agent to hold as Pledged Equity and shall, if received by any Grantor, be received in trust for the benefit of the Collateral Agent (for the ratable benefit of the Collateral Agent and the Noteholders), be segregated from the other property or funds of such Grantor, and be forthwith delivered to the Collateral Agent as Pledged Equity in the same form as so received (with any necessary endorsement).

SECTION 8. Remedies Upon Event of Default; Application of Proceeds. If any Event of Default shall have occurred and be continuing:

(a) The Collateral Agent may exercise in respect of the Collateral, in addition to any other rights and remedies provided for herein, in any other Transaction Document or otherwise available to it, all of the rights and remedies of a secured party upon default under the Code (whether or not the Code applies to the affected Collateral), and also may (i) take absolute control of the Collateral, including, without limitation, transfer into the Collateral Agent’s name or into the name of its nominee or nominees (to the extent the Collateral Agent has not theretofore done so) and thereafter receive, for the ratable benefit of itself and the Noteholders, all payments made thereon, give all consents, waivers and ratifications in respect thereof and otherwise act with respect thereto as though it were the outright owner thereof, and (ii) without advance notice except as specified below and without any obligation to prepare or process the Collateral for sale (provided that the Collateral Agent shall give notice to any Grantor as promptly as practicable with respect to any such sale), (A) sell the Collateral or any part thereof in one or more parcels at public or private sale (including, without limitation, by credit bid), at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, and at such price or prices and upon such other terms as the Collateral Agent may deem commercially reasonable and/or (B) lease, license or dispose of the Collateral or any part thereof upon such terms as the Collateral Agent may deem commercially reasonable. Each Grantor agrees that, to the extent notice of sale or any other disposition of its respective Collateral shall be required by law, at least ten (10) days’ notice to any Grantor of the time and place of any public sale or the time after which any private sale or other disposition of its respective Collateral is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale or other disposition of any Collateral regardless of notice of sale having been given. The Collateral Agent 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. Each Grantor hereby waives any claims against the Collateral Agent and the Noteholders arising by reason of the fact that the price at which its respective Collateral may have been sold at a private sale was less than the price which might have been obtained at a public sale or was less than the aggregate amount of the Obligations, even if the Collateral Agent accepts the first offer received and does not offer such Collateral to more than one offeree, and waives all rights that any Grantor may have to require that all or any part of such Collateral be marshaled upon any sale (public or private) thereof. Each Grantor hereby acknowledges that (i) any such sale of its respective Collateral by the Collateral Agent shall be made without warranty, (ii) the Collateral Agent may specifically disclaim any warranties of title, possession, quiet enjoyment or the like, and (iii) such actions set forth in clauses (i) and (ii) above shall not adversely affect the commercial reasonableness of any such sale of Collateral.

(b) Any cash held by the Collateral Agent as Collateral and all Cash Proceeds received by the Collateral Agent in respect of any sale or disposition of or collection from, or other realization upon, all or any part of the Collateral shall be applied as follows (subject to the provisions of the Securities Purchase Agreement): first, to pay any fees, indemnities or expense reimbursements then due to the Collateral Agent (including, without limitation, those described in Section 9 hereof); second, to pay any fees, indemnities or expense reimbursements then due to the Noteholders, on a pro rata basis; third to pay interest due under the Notes owing to the Noteholders, on a pro rata basis; fourth, to pay or prepay principal in respect of the Notes, whether or not then due, owing to the Noteholders, on a pro rata basis; fifth, to pay or prepay any other Obligations, whether or not then due, in such order and manner as the Collateral Agent shall elect, consistent with the provisions of the Securities Purchase Agreement. Any surplus of such cash or Cash Proceeds held by the Collateral Agent and remaining after the full performance and Payment in Full of all of the Obligations shall be paid over to the Company or as a court of competent jurisdiction may otherwise direct.

(c) To the extent that applicable law imposes duties on the Collateral Agent to exercise rights and remedies in a commercially reasonable manner, each Grantor acknowledges and agrees that it is commercially reasonable for the Collateral Agent (i) to fail to incur expenses deemed significant by the Collateral Agent to prepare Collateral for disposition or otherwise to transform raw material or work in process into finished goods or other finished products for disposition, (ii) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (iii) to fail to exercise collection remedies against Account Debtors or other Persons obligated on Collateral or to remove Liens on or any adverse claims against Collateral, (iv) to exercise collection remedies against Account Debtors and other Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (v) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (vi) to contact other Persons, whether or not in the same business as any Grantor, for expressions of interest in acquiring all or any portion of such Collateral, (vii) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, (viii) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets, (ix) to dispose of assets in wholesale rather than retail markets, (x) to disclaim disposition warranties, such as title, possession or quiet enjoyment, (xi) to purchase insurance or credit enhancements to insure the Collateral Agent against risks of loss, collection or disposition of Collateral or to provide to the Collateral Agent a guaranteed return from the collection or disposition of Collateral, or (xii) to the extent deemed appropriate by the Collateral Agent, to obtain the services of brokers, investment bankers, consultants, attorneys and other professionals to assist the Collateral Agent in the collection or disposition of any of the Collateral. Each Grantor acknowledges that the purpose of this section is to provide non-exhaustive indications of what actions or omissions by the Collateral Agent would be commercially reasonable in the Collateral Agent’s exercise of rights and remedies against the Collateral and that other actions or omissions by the Collateral Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this section. Without limitation of the foregoing, nothing contained in this section shall be construed to grant any rights to any Grantor or to impose any duties on the Collateral Agent that would not have been granted or imposed by this Agreement or by applicable law in the absence of this section.

Section 9. Indemnity and Expenses.

(a) Each Grantor agrees, jointly and severally, to defend, protect, indemnify and hold the Collateral Agent and each of the Noteholders harmless from and against any and all claims, damages, losses, liabilities, obligations, penalties, fees, costs and expenses (including, without limitation, reasonable legal fees, costs, expenses, and disbursements of such Person’s counsel) to the extent that they arise out of or otherwise result from this Agreement (including, without limitation, enforcement of this Agreement), except to the extent resulting from such Person’s gross negligence or willful misconduct, as determined by a final judgment of a court of competent jurisdiction no longer subject to appeal.

(b) Each Grantor agrees, jointly and severally, to pay to the Collateral Agent upon demand the amount of any and all reasonable, out of pocket costs and expenses, including the reasonable fees, costs, expenses and disbursements of counsel for the Collateral Agent and of any experts and agents (including, without limitation, any collateral trustee which may act as agent of the Collateral Agent), which the Collateral Agent may incur in connection with (i) the preparation, negotiation, execution, delivery, recordation, administration, amendment, waiver or other modification or termination of this Agreement, (ii) the custody, preservation, use or operation of, or the sale of, collection from, or other realization upon, any Collateral, (iii) the exercise or enforcement of any of the rights or remedies of the Collateral Agent hereunder, or (iv) the failure by any Grantor to perform or observe any of the provisions hereof.

SECTION 10. Notices, Etc. All notices and other communications provided for hereunder shall be in writing and shall be mailed (by certified mail, first-class postage prepaid and return receipt requested), telecopied, e-mailed or delivered, if to any Grantor, to the Company’s address, or if to the Collateral Agent or any Noteholder, to it at its respective address, each as set forth in Section 7(f) of the Securities Purchase Agreement; or as to any such Person, at such other address as shall be designated by such Person in a written notice to all other parties hereto complying as to delivery with the terms of this Section 10. All such notices and other communications shall be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) with respect to notice sent by electronic mail (provided that such sent email is kept on file (whether electronically or otherwise) by the sending party and the sending party does not receive an automatically generated message from the recipient’s email server that such e-mail could not be delivered to such recipient) (A) if sent prior to 6:00 PM New York time on any Business Day, when sent, or (B) if sent on or after 6:00 PM New York time on any Trading Day (as defined in the Securities Purchase Agreement), on the next Business Day; or (iii) one (1) Business Day after deposit with an overnight courier service with next day delivery specified, in each case, properly addressed to the party to receive the same.

Section 11. Miscellaneous.

(a) No amendment of any provision of this Agreement shall be effective unless it is in writing and signed by each Grantor and the Collateral Agent (and approved by the Required Holders), and no waiver of any provision of this Agreement, and no consent to any departure by each Grantor therefrom, shall be effective unless it is in writing and signed by each Grantor and the Collateral Agent (and approved by the Required Holders), and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No amendment, modification or waiver of this Agreement shall be effective to the extent that it (1) applies to fewer than all of the holders of Notes or (2) imposes any obligation or liability on any holder of Notes without such holder’s prior written consent (which may be granted or withheld in such holder’s sole and absolute discretion).

(b) No failure on the part of the Collateral Agent to exercise, and no delay in exercising, any right or remedy hereunder or under any of the other Transaction Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any such right or remedy preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies of the Collateral Agent or any Noteholder provided herein and in the other Transaction Documents are cumulative and are in addition to, and not exclusive of, any rights or remedies provided by law. The rights and remedies of the Collateral Agent or any Noteholder under any of the other Transaction Documents against any party thereto are not conditional or contingent on any attempt by such Person to exercise any of its rights or remedies under any of the other Transaction Documents against such party or against any other Person, including but not limited to, any Grantor.

(c) Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining portions hereof or thereof or affecting the validity or enforceability of such provision in any other jurisdiction.

(d) This Agreement shall create a continuing Lien on and security interest in the Collateral and shall (i) remain in full force and effect until the full performance and Payment in Full of the Obligations, and (ii) be binding on each Grantor and all other Persons who become bound as debtor to this Agreement in accordance with Section 9-203(d) of the Code and shall inure, together with all rights and remedies of the Collateral Agent and the Noteholders hereunder, to the ratable benefit of the Collateral Agent and the Noteholders and their respective permitted successors, transferees and assigns. Without limiting the generality of clause (ii) of the immediately preceding sentence, without notice to any Grantor, the Collateral Agent and the Noteholders may assign or otherwise transfer their rights and obligations under this Agreement and any of the other Transaction Documents, to any other Person and such other Person shall thereupon become vested with all of the benefits in respect thereof granted to the Collateral Agent and the Noteholders herein or otherwise. Upon any such assignment or transfer, all references in this Agreement to the Collateral Agent or any such Noteholder shall mean the assignee of the Collateral Agent or such Noteholder. None of the rights or obligations of any Grantor hereunder may be assigned, delegated or otherwise transferred without the prior written consent of the Collateral Agent in its sole and absolute discretion, and any such assignment, delegation or transfer without such consent of the Collateral Agent shall be null and void.

(e) Upon the full performance and Payment in Full of the Obligations, (i) this Agreement and the security interests created hereby shall terminate and all rights to the Collateral shall revert to the respective Grantor that granted such security interests hereunder, and (ii) the Collateral Agent will, upon any Grantor’s request and at such Grantor’s expense, (A) return to such Grantor such of the Collateral as shall not have been sold or otherwise disposed of or applied pursuant to the terms hereof and (B) execute and deliver to such Grantor such documents as such Grantor shall reasonably request to evidence such termination, all without any representation, warranty or recourse whatsoever.

(f) Governing Law; Jurisdiction; Jury Trial.

(i) All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any provision or rule of law (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdiction other than the State of New York.

(ii) Each Party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or under any of the other Transaction Documents or with any transaction contemplated hereby or thereby, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim, defense or objection that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under Section 7(f) of each of the Securities Purchase Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall be deemed or operate to preclude the Collateral Agent or the Noteholders from bringing suit or taking other legal action against any Grantor in any other jurisdiction to collect on a Grantor’s obligations or to enforce a judgment or other court ruling in favor of the Collateral Agent or a Noteholder.

(iii) WAIVER OF JURY TRIAL, ETC. EACH PARTY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR UNDER ANY OTHER TRANSACTION DOCUMENT OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT, ANY OTHER TRANSACTION DOCUMENT OR ANY TRANSACTION CONTEMPLATED HEREBY OR THEREBY.

(iv) Each Party irrevocably and unconditionally waives any right it may have to claim or recover in any legal action, suit or proceeding referred to in this Section any special, exemplary, indirect, incidental, punitive or consequential damages.
