PROMISSORY NOTE

FOR VALUE RECEIVED, Clearday, Inc., a Delaware corporation which was formerly known as Superconductor Technologies Inc. (along with its subsidiaries, “Borrower”), promises to pay to A.G.P./Alliance Global Partners (“Lender”), the principal sum first set forth above (the “Loan Amount”) at Lender’s office, or at such other place as Lender may from time to time designate in writing, in lawful money of the United States, together with all accrued interest thereon as provided in this Promissory Note (this “Note”), and all other amounts due and payable under this Note, as they may be amended, restated, supplemented, or otherwise modified from time to time in accordance with their terms. This Note is issued further to the terms and conditions of that that certain Advisory Agreement dated July 25, 2019 by and between Lender and AIU Alternative Care, Inc., an acronym of Borrower, as amended by an Addendum to Advisory Agreement dated as of November 1, 2019 (the “Advisory Agreement”); capitalized terms not otherwise defined herein shall have the same meaning as defined in the Advisory Agreement and is payment for the services under the Advisory Agreement as of the date of this Note.

1. Acknowledgement of Obligations. The Borrower has effected a merger further to an Agreement and Plan of Merger (as amended from time to time, the “Merger Agreement”) by and among Superconductor Technologies Inc. (“Superconductor”), AIU Special Merger Company, Inc., a Delaware corporation and wholly-owned subsidiary of Superconductor (“Merger Sub”), and Allied Integral United, Inc., a Delaware corporation that conducts its business under the trade name Clearday (“AIU”) further to which Merger Sub merged with and into AIU, with AIU continuing as a wholly-owned subsidiary of Superconductor, further to which AIU is currently required to have paid Lender an aggregate fee that is equal to the Loan Amount (the “Deferred Fee Amount”). Borrower hereby acknowledges, confirms and agrees that as of the date hereof, Borrower is indebted to Lender under the Advisory Agreement in an amount equal to the Deferred Fee Amount, plus any other fees, costs, expenses and other charges now or hereafter payable under the Advisory Agreement, notwithstanding that the Advisory Agreement was executed by AIU Alternative Care, Inc. (collectively, the “Obligations”) and such Obligations are unconditionally owed by Borrower to Lender, without offset, defense or counterclaim of any kind, nature or description whatsoever. Superconductor hereby assumes the Obligations of AIU Alternative Care, Inc. and AIU under the Advisory Agreement and the Lender, as party to the Advisory Agreement, permits the full assignment of all rights of AIU Alternative Care, Inc. and AIU under the Advisory Agreement to Superconductor.

2. Interest. Except as otherwise provided in this Note, the outstanding Loan Amount shall accrue interest at a rate per annum equal to two percent (2%) (the “Interest Rate”) from the Initial Payment Date (as defined below) until the entire Loan Amount, all accrued and unpaid interest thereon, and all other amounts and indebtedness payable under this Note, are paid in full, whether at maturity, upon acceleration, by prepayment, or otherwise.

3. Computation of Interest. All computations of interest shall be made on the basis of the actual number of days elapsed in a year of 365 days. Interest shall commence to accrue on the Loan Amount on the Initial Payment Date, and shall not accrue on the Loan Amount on the day on which it is paid if payment is made to Lender prior to 12:00 p.m. Pacific time. Any payment of principal on this Note after 12:00 p.m. Pacific time on any Business Day shall be credited against this Note on the next Business Day and interest will continue to accrue until so credited. As used herein, “Business Day” means a day other than a Saturday, Sunday, or other day on which commercial banks in New York, New York are authorized or required by law to close.

4. Scheduled Payments and Due Date.

4.1 The Borrower will make payments as provided in this Section 4:

4.2 On or prior to October 8, 2021 (the “Initial Payment Date”), the Borrower shall make a payment of $60,000 against amounts due under this Note.

4.3 From and after the Initial Payment Date, monthly payments of $30,000 shall be made on the 8th calendar day of each subsequent month.

4.4 On the earlier of (i) the date that is one year from the Initial Payment Date (the “Maturity Date”) and (ii) the date on which all amounts under the Note shall become due and payable pursuant to Section 8, the aggregate amount of the then outstanding and unpaid Loan Amount, together with all accrued and unpaid interest thereon, shall become immediately due and payable in full.

5. Prepayments. Borrower may make voluntary prepayments of the principal balance of this Note, in full at any time or in part from time to time, without premium or penalty; provided, however, that Borrower shall be required to prepay the then outstanding principal balance of this Note with 50% of the net proceeds (which shall be deemed gross proceeds minus direct selling costs, expenses and commissions) received, directly or indirectly, by Borrower and/or its subsidiaries from the issuance of any equity or equity-linked financing (including convertible debt), less any selling commissions.

6. Application of Payment. All payments made hereunder shall be applied : first, to the payment of any fees or charges outstanding hereunder and/or under the Advisory Agreement (that have not been paid by this Note) as determined by Lender in its sole discretion; second, to accrued interest at the Interest Rate or the Default Rate, as applicable; and third, to the payment of the principal amount outstanding under this Note. However, after an Event of Default, all payments made hereunder may be applied by Lender in such order, priority and in such proportion as Lender shall elect in its sole discretion. No amount repaid hereunder may be re-borrowed.

7. Default Interest. If any amount payable under this Note is not paid when due (without regard to any applicable grace periods), whether at the stated maturity, by acceleration or otherwise, the outstanding Loan Amount of this Note shall bear interest at the Interest Rate plus 5% (the “Default Rate”) from the date payment was due until such delinquent payment is paid in full. Borrower acknowledges that it would be extremely difficult or impracticable to determine Lender’s actual damages resulting from any late payment or default, and such interest at the Default Rate is a reasonable estimate of those damages and does not constitute a penalty.

8. Events of Default. The occurrence of any of the following events shall constitute an event of default (an “Event of Default”) under this Note:

8.1 Failure to Pay. Borrower fails to pay any principal amount, interest or any other amount when due under this Note.

8.2 Default Under any A.G.P. Agreement. Borrower fails to perform any other obligation set forth in this Note or the Advisory Agreement beyond the expiration of all applicable notice and grace periods.

8.3 Assignment for the Benefit of Creditors. Borrower makes an assignment for the benefit of creditors, or generally fails to pay its debts as they become due and such failure continues after the applicable grace period, if any, specified in the agreement or instrument relating to such indebtedness.

8.4 Bankruptcy. (i) Borrower commences any case, proceeding, petition, or other action seeking appointment of a receiver, liquidator or trustee for Borrower or for all or substantially all of Borrower’s assets; (ii) Borrower is adjudicated as bankrupt or insolvent; (iii) any petition for bankruptcy, reorganization or other arrangement pursuant to federal bankruptcy law, or any similar federal or state law, is filed by or against, consented to, or acquiesced in by, Borrower; or (iv) any proceeding for the dissolution or liquidation of Borrower is instituted; provided, however, that if such appointment, adjudication, petition or proceeding (each, a “Bankruptcy Action”) was involuntary and not consented to by Borrower, then no Event of Default will be deemed to have occurred if such Bankruptcy Action is discharged, stayed or dismissed within 60 days.

9. Remedies. Upon the occurrence of an Event of Default and at any time thereafter and during the continuance of such Event of Default, (i) the parties expressly understand and agree that the Deferred Fee Amount shall not be in any way reduced (other than by the Initial Payment) or subject to this Note and the entire unpaid balance on the Deferred Fee Amount shall then again become immediately due and payable and (ii) the Lender may exercise any or all of its rights, powers, or remedies under the Advisory Agreement or applicable law or available in equity. The remedies of Lender, as provided in this Note and the Advisory Agreement, shall be cumulative and concurrent and may be pursued singly, successively, or together, at the sole discretion of Lender, and may be exercised as often as occasion therefor shall occur; and the failure to exercise any such right or remedy shall in no event be construed as a waiver or release thereof.

10. No Waiver. No failure to exercise and no delay in exercising on the part offender, of any right, remedy, power, or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power, or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power, or privilege. No waiver by Lender of any of its rights or of any such breach, default, or failure of condition shall be effective, unless the waiver is expressly stated in a writing signed by Lender.

11. Waivers. Borrower hereby waives presentment, demand for payment, protest, notice of dishonor, notice of protest or nonpayment, notice of intent to accelerate, notice of acceleration of maturity, and diligence in connection with the enforcement of this Note or the taking of any action to collect sums owing hereunder.

12. Expenses. Borrower shall reimburse Lender on demand for all out-of-pocket costs, expenses, and fees (including expenses and fees of its counsel) incurred by Lender in connection with the collection of this Note and the enforcement of Lender’s rights hereunder and thereunder.

13. Governing Law. This Note and any claim, controversy, dispute, or cause of action (whether in contract, equity, tort, or otherwise) based upon, arising out of, or relating to this Note and the transactions contemplated hereby shall be governed by the laws of the State of New York without giving effect to its principles of choice of law or conflicts of law.
