Subordinated Promissory Note by and between the Company and AirStrip Technologies, Inc. dated as of October 3, 2022

1.Principal and Interest. For value received, NantHealth, Inc., a Delaware corporation, with offices at 3000 RDU Drive, Suite 200 Morrisville, North Carolina 27560 (the “Company”) promises to pay to the order of Airstrip Technologies, Inc., a Delaware corporation, with officers at 2915 W. Bitters Road, Suite 215, San Antonio, TX 78248 (“Holder”), or to the order of Holder’s registered assigns, the principal amount of each advance (each, an “Advance” and, collectively, the “Advances”) made by Holder to the Company pursuant to this Subordinated Promissory Note (this “Note”), in immediately available funds, at the times and in the manner set forth herein.

(a)Advances. The principal amount of each Advance made by Holder to the Company hereunder, the date on which each such Advance is made, the amount of any prepayment or partial prepayment of any such Advance, and the outstanding principal amount of each such Advance, shall be specified in Schedule A attached hereto. Holder shall be entitled to update Schedule A hereto from time to time to reflect updated information relating to the Advances made by Holder to the Company hereunder and any prepayments or partial prepayments of the outstanding principal amounts of any such Advances. The information reflected in any such updated version of Schedule A delivered by Holder to the Company shall, in the absence of manifest error, constitute prima facie evidence of the accuracy of the information recorded, provided, however, that the failure of Holder to update the information specified in Schedule A in connection with the making by Holder to the Company of any Advance or the payment or partial prepayment by the Company of any such Advance shall not affect the obligations of the Company hereunder to repay the principal amount of any such Advance (and any interest unpaid having accrued thereon) in accordance with the terms of this Note.

(b)Interest. The outstanding principal amount of each Advance made by Holder to the Company pursuant to this Note shall bear interest from and including the date such Advance is made to but excluding the date such Advance is paid in full at a per annum rate equal to eight and one-half percent (8.5%), compounded annually and computed on the basis of the actual number of days elapsed and a year of 365 or 366 days, as the case may be. All amounts of principal of and, to the extent permitted by law, interest due and payable with respect to any Advance not paid when due, whether upon demand of Holder or upon the acceleration thereof pursuant to Section 2 hereof, shall bear interest (“Default Interest”) from the date due until the date paid in full at an overdue rate per annum equal to ten and one-half percent (10.5%). Such Default Interest shall be payable on demand and such and such increased rate of interest shall continue until such delinquent amount(s), with interest thereon at such increased rate, shall have been paid in full. Acceptance of any delinquent payments by Holder shall not waive or affect any prior demand or default.

(c)Maturity Date. The unpaid principal of each Advance, and any accrued and unpaid interest thereon, shall be due and payable on October 31, 2026 (the “Maturity Date”). Subject to Section 3, the Company may prepay the outstanding amount of any Advance (together with accrued and unpaid interest thereon) at any time, either in whole or in part, without premium or penalty and without the prior consent of Holder..

2.Events of Default. The entire aggregate principal amount of the Advances made by Holder pursuant to this Note, together with all accrued and unpaid interest thereon, is subject to prepayment in whole or in part upon the initiation of any bankruptcy, insolvency, moratorium, receivership or reorganization by or against the Company, or a general assignment of assets by the Company for the benefit of creditors (each, an “Event of Default”). Upon the occurrence of any Event of Default, all amounts outstanding hereunder in respect of the principal amount of any Advance and all unpaid interest having accrued thereon, shall be immediately due and payable without notice to or demand on the Company. For the avoidance of doubt, any payment obligation of the Company pursuant to this Section 2 is subject to Section 3.

3.Subordination.

(d)Agreement of Subordination. The Company and the Holder each covenant and agree that the Note shall be issued subject to the provisions of this Section 3; and each holder of the Note, whether upon original issue or upon transfer, assignment or exchange thereof, accepts and agrees to be bound by such provisions. The payment of the principal of, premium, if any, and interest on the Note shall, to the extent and in the manner hereinafter set forth, be subordinated and subject in right of payment to the prior payment in full of all Senior Debt (as defined below), whether outstanding at the date of this Note or thereafter incurred.

(ii)In the case of a Payment Default, the Company may and shall resume payments on and distributions in respect of the Note upon the earlier of the date upon which the Payment Default is cured or waived or ceases to exist, or unless this Section 3 otherwise prohibits the payment or distribution at such time.

(iii)Upon any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any dissolution or winding-up or liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency, reorganization, liquidation, receivership or other proceedings, or upon an assignment for the benefit of creditors or any marshalling of the assets and liabilities of the Company, or otherwise, all amounts due or to become due upon all Senior Debt shall first be paid in full in cash or other payment satisfactory to the holders of such Senior Debt, or payment thereof in accordance with its terms provided for in cash or other payment satisfactory to the holders of such Senior Debt, before any payment is made on account of the principal of, interest or premium, if any, on the Note; and upon any such dissolution, winding-up, liquidation, reorganization, assignment for the benefit of creditors or marshalling of assets and liabilities of the Company or bankruptcy, insolvency, receivership or other proceeding, any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Holder would be entitled, except for the provision of this Section 3, shall (except as aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, or by the Holder if received by them or it, directly to the holders of Senior Debt (pro rata to such holders on the basis of the respective amounts of Senior Debt held by such holders, or as otherwise required by law or a court order), or to the trustee or trustees under the indenture pursuant to which the Senior Debt was issued, as their respective interests may appear, to the extent necessary to pay all Senior Debt in full, in cash or other payment satisfactory to the holders of such Senior Debt, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt, before any payment or distribution or provision therefor is made to the Holder.

(iv)For purposes of this Section 3, the words, “cash, property or securities” shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Section 3 with respect to the Note to the payment of all Senior Debt which may at the time be outstanding; provided that (i) the Senior Debt is assumed by the new corporation, if any, resulting from any reorganization or readjustment, and (ii) the rights of the holders of Senior Debt are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another corporation shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 3(b) unless such consolidation, merger, conveyance or transfer, shall constitute an Event of Default in Section 2.

(v)In the event of the acceleration of the Note because of an Event of Default, no payment or distribution shall be made to the Holder in respect of the principal of, interest or premium, if any, on the Note until all Senior Debt has been paid in full in cash or other payment satisfactory to the holders of Senior Debt or such acceleration is rescinded by the Holder.
