FOR
VALUE RECEIVED, Hemispherx Biopharma, Inc., a Delaware corporation (“Borrower”),
promises to pay to Chicago Venture Partners, L.P., a Utah limited partnership, or
its successors or assigns (“Lender”), $2,635,000.00 and any interest, fees, charges, and late fees accrued
hereunder on the date that is twenty-four (24) months after the Purchase Price Date (the “Maturity Date”) in
accordance with the terms set forth herein and to pay interest on the Outstanding Balance at the rate of ten percent (10%) per
annum from the Purchase Price Date until the same is paid in full. All interest calculations hereunder shall be computed on the
basis of a 360-day year comprised of twelve (12) thirty (30) day months, shall compound daily and shall be payable in accordance
with the terms of this Note. This Secured Promissory Note (this “Note”) is issued and made effective as of
August 5, 2019 (the “Effective Date”). This Note is issued pursuant to that certain Note Purchase Agreement
dated August 5, 2019, as the same may be amended from time to time, by and between Borrower and Lender (the “Purchase
Agreement”). Certain capitalized terms used herein are defined in Attachment 1 attached hereto and incorporated
herein by this reference.

 

This
Note carries an OID of $625,000.00. In addition, Borrower agrees to pay $10,000.00 to Lender to cover Lender’s legal fees,
accounting costs, due diligence, monitoring and other transaction costs incurred in connection with the purchase and sale of this
Note (the “Transaction Expense Amount”), all of which amount is fully earned and included in the initial principal
balance of this Note. The purchase price for this Note shall be $2,000,000.00 (the “Purchase Price”), computed
as follows: $2,635,000.00 original principal balance, less the OID, less the Transaction Expense Amount. The Purchase Price shall
be payable by Lender by wire transfer of immediately available funds.

 

 1. Payment; Prepayment.

 

1.1.
Payment. All payments owing hereunder shall be in lawful money of the United States of America and delivered to Lender
at the address or bank account furnished to Borrower for that purpose. All payments shall be applied first to (a) costs of collection,
if any, then to (b) fees and charges, if any, then to (c) accrued and unpaid interest, and thereafter, to (d) principal.

 

1.2.
Prepayment. Borrower may pay all or any portion of the amount owed earlier than it is due; provided that in the
event Borrower elects to prepay all or any portion of the outstanding balance on or before the date that is twelve (12) months
from the date hereof, the Outstanding Balance shall be reduced by an amount equal to the amount Borrower elects to prepay divided
by 80% (for illustration purposes only, if Borrower elects to prepay $100,000.00 on the date that is six (6) months from the date
hereof, it shall receive a $125,000.00 reduction of the Outstanding Balance). The foregoing prepayment credit shall not apply
to any prepayments received by Lender after the date that is twelve (12) months from the date of this Note. Early payments of
less than all principal, fees and interest outstanding will not, unless agreed to by Lender in writing, relieve Borrower of Borrower’s
remaining obligations hereunder.

 

    	 	 	 

    	 	 	 

    

 

2.
Security. This Note is secured by the Security Agreement (as defined in the Purchase Agreement), executed by Borrower in
favor of Lender encumbering the collateral set forth therein, as more specifically set forth in the Security Agreement, all the
terms and conditions of which are hereby incorporated into and made a part of this Note.

 

3.
Redemption; Minimum Payment.

 

3.1.
Redemption. Beginning on the date that is six (6) months after the Purchase Price Date, Lender shall have the right, exercisable
at any time in its sole and absolute discretion, to redeem any amount of this Note up to $325,000.00 (such amount, the “Redemption
Amount”) per calendar month by providing written notice to Borrower (each, a “Redemption Notice”).
For the avoidance of doubt, Lender may submit to Borrower one (1) or more Redemption Notices in any given calendar month so long
as the aggregate amount being redeemed in such month does not exceed $325,000.00. Upon receipt of any Redemption Notice, Borrower
shall pay the applicable Redemption Amount in cash to Lender within three (3) Business Days of Borrower’s receipt of such
Redemption Notice.

 

3.2.
Minimum Payment. Beginning on the last day of each calendar month following the date that is twelve (12) months from the
Purchase Price Date and on the last day of each calendar month thereafter, if the total amount redeemed during such calendar month
is less than the Minimum Monthly Redemption Amount, then Borrower shall make a cash payment (unless otherwise negotiated) to Lender
in an amount equal to the Minimum Monthly Redemption Amount less the amount redeemed in such calendar month (the “Minimum
Payment”). In the event Borrower fails to timely make the Minimum Payment, the Outstanding Balance will automatically
be increased by three percent (3%) (without the need for Lender to provide any notice to Borrower of such increase). For the avoidance
of doubt, such increase to the Outstanding Balance shall be in addition to all other rights and remedies available to Lender under
this Note and the other Transaction Documents and shall not be in lieu of, nor deemed to be a waiver of any other rights or remedies
available to Lender under this Note or any of the other Transaction Documents, including without limitation calling an Event of
Default if Borrower fails to make the Minimum Payment.

 

4.
Defaults and Remedies.

 

4.1.
Defaults. The following are events of default under this Note (each, an “Event of Default”): (a) Borrower
fails to pay any principal, interest, fees, charges, or any other amount when due and payable hereunder; (b) a receiver, trustee
or other similar official shall be appointed over Borrower or a material part of its assets and such appointment shall remain
uncontested for twenty (20) days or shall not be dismissed or discharged within sixty (60) days; (c) Borrower becomes insolvent
or generally fails to pay, or admits in writing its inability to pay, its debts as they become due, subject to applicable grace
periods, if any; (d) Borrower makes a general assignment for the benefit of creditors; (e) Borrower files a petition for relief
under any bankruptcy, insolvency or similar law (domestic or foreign); (f) an involuntary bankruptcy proceeding is commenced or

Note defaults or otherwise fails to observe or perform any covenant, obligation, condition or agreement of Borrower or such pledgor,
trustor, or guarantor contained herein or in any other Transaction Document (as defined in the Purchase Agreement), other than
those specifically set forth in this Section 4.1 and Section 4 of the Purchase Agreement and such default or failure remains uncured
for a period of ten (10) days after written notice to Company by Lender of such default or failure; (h) any representation, warranty
or other statement made or furnished by or on behalf of Borrower or any pledgor, trustor, or guarantor of this Note to Lender

4.2.
Remedies. At any time and from time to time after Lender becomes aware of the occurrence of any Event of Default, Lender
may accelerate this Note by written notice to Borrower, with the Outstanding Balance becoming immediately due and payable in cash
at the Mandatory Default Amount. Notwithstanding the foregoing, at any time following the occurrence of any Event of Default,
Lender may, at its option, elect to increase the Outstanding Balance by applying the Default Effect (subject to the limitation
set forth below) via written notice to Borrower without accelerating the Outstanding Balance, in which event the Outstanding Balance
shall be increased as of the date of the occurrence of the applicable Event of Default pursuant to the Default Effect, but the
Outstanding Balance shall not be immediately due and payable unless so declared by Lender (for the avoidance of doubt, if Lender
elects to apply the Default Effect pursuant to this sentence, it shall reserve the right to declare the Outstanding Balance immediately
due and payable at any time and no such election by Lender shall be deemed to be a waiver of its right to declare the Outstanding
Balance immediately due and payable as set forth herein unless otherwise agreed to by Lender in writing). Notwithstanding the
foregoing, upon the occurrence of any Event of Default described in clauses (b), (c), (d), (e) or (f) of Section 4.1, the Outstanding
Balance as of the date of acceleration shall become immediately and automatically due and payable in cash at the Mandatory Default
Amount, without any written notice required by Lender. At any time following the occurrence of any Event of Default, upon written
notice given by Lender to Borrower, interest shall accrue on the Outstanding Balance beginning on the date the applicable Event
of Default occurred at an interest rate equal to the lesser of twenty-two percent (22%) per annum or the maximum rate permitted
under applicable law (“Default Interest”). In connection with acceleration described herein, Lender need not
provide, and Borrower hereby waives, any presentment, demand, protest or other notice of any kind, and Lender may immediately
and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available
to it under applicable law. Such acceleration may be rescinded and annulled by Lender at any time prior to payment hereunder and
Lender shall have all rights as a holder of the Note until such time, if any, as Lender receives full payment pursuant to this
Section 4.2. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon.
Nothing herein shall limit Lender’s right to pursue any other remedies available to it at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief.

 

5.
Unconditional Obligation; No Offset. Borrower acknowledges that this Note is an unconditional, valid, binding and enforceable
obligation of Borrower not subject to offset, deduction or counterclaim of any kind. Borrower hereby waives any rights of offset
it now has or may have hereafter against Lender, its successors and assigns, and agrees to make the payments called for herein
in accordance with the terms of this Note.

 

6.
Waiver. No waiver of any provision of this Note shall be effective unless it is in the form of a writing signed by the
party granting the waiver. No waiver of any provision or consent to any prohibited action shall constitute a waiver of any other
provision or consent to any other prohibited action, whether or not similar. No waiver or consent shall constitute a continuing
waiver or consent or commit a party to provide a waiver or consent in the future except to the extent specifically set forth in
writing.

 

    	 	3	 

    	 	 	 

    

 

7.
Approved Restricted Issuance. The Outstanding Balance will automatically be increased by three percent (3%) for each Approved
Restricted Issuance made by Borrower (without the need for Lender to provide any notice to Borrower of such increase), which increase
will be effective as of the date of each applicable Approved Restricted Issuance.

 

8.
Opinion of Counsel. In the event that an opinion of counsel is needed for any matter related to this Note, Lender has the
right to have any such opinion provided by its counsel.

 

9.
Governing Law; Venue. This Note shall be construed and enforced in accordance with, and all questions concerning the construction,
validity, interpretation and performance of this Note shall be governed by, the internal laws of the State of Utah, without giving
effect to any choice of law or conflict of law provision or rule (whether of the State of Utah or any other jurisdiction) that
would cause the application of the laws of any jurisdiction other than the State of Utah. The provisions set forth in the Purchase
Agreement to determine the proper venue for any disputes are incorporated herein by this reference.

 

10.
Arbitration of Disputes. By its issuance or acceptance of this Note, each party agrees to be bound by the Arbitration Provisions
(as defined in the Purchase Agreement) set forth as an exhibit to the Purchase Agreement.

 

11.
Cancellation. After repayment of the entire Outstanding Balance, this Note shall be deemed paid in full, shall automatically
be deemed canceled, and shall not be reissued.

 

12.
Amendments. The prior written consent of both parties hereto shall be required for any change or amendment to this Note.

 

13.
Assignments. Borrower may not assign this Note without the prior written consent of Lender. This Note may be offered, sold,
assigned or transferred by Lender without the consent of Borrower, so long as such transfer is in accordance with applicable federal
and state securities laws.

 

14.
Notices. Whenever notice is required to be given under this Note, unless otherwise provided herein, such notice shall be
given in accordance with the subsection of the Purchase Agreement titled “Notices.”

 

15.
Liquidated Damages. Lender and Borrower agree that in the event Borrower fails to comply with any of the terms or provisions
of this Note, Lender’s damages would be uncertain and difficult (if not impossible) to accurately estimate because of the
parties’ inability to predict future interest rates, future share prices, future trading volumes and other relevant factors.
Accordingly, Lender and Borrower agree that any fees, balance adjustments, Default Interest or other charges assessed under this
Note are not penalties but instead are intended by the parties to be, and shall be deemed, liquidated damages.

 

16.
Severability. If any part of this Note is construed to be in violation of any law, such part shall be modified to achieve
the objective of Borrower and Lender to the fullest extent permitted by law and the balance of this Note shall remain in full
force and effect.

by legal proceedings or otherwise and endorse, receive and receipt for all dividends, interest, payments, proceeds and other sums
and property now or hereafter payable on or on account of the Collateral; (b) enter into any extension, reorganization, deposit,
merger, consolidation or other agreement pertaining to, or deposit, surrender, accept, hold or apply other property in exchange
for the Collateral; (c) make any compromise or settlement, and take any action Secured Party deems advisable, with respect to
the Collateral; (d) file a copy of this Agreement with any governmental agency, body or authority, at the sole cost and expense
of Debtor; (e) insure, process and preserve the Collateral; (f) pay any indebtedness of Debtor relating to the Collateral; (g)
execute and file UCC financing statements and other documents, certificates, instruments and agreements with respect to the Collateral
or as otherwise required or permitted hereunder; and (h) take any and all appropriate action and execute any and all documents
and instruments that may be necessary or useful to accomplish the purposes of this Agreement; provided, however, that Secured
Party shall not exercise any such powers granted pursuant to clauses (a) through (c) above prior to the occurrence of an Event
of Default and shall only exercise such powers during the continuance of an Event of Default. The powers conferred on Secured
Party under this Section 6 are solely to protect its interests in the Collateral and shall not impose any duty upon it to exercise
any such powers. Secured Party shall be accountable only for the amounts that it actually receives as a result of the exercise
of such powers, and neither Secured Party nor any of its stockholders, directors, officers, managers, employees or agents shall
be responsible to Debtor for any act or failure to act, except with respect to Secured Party’s own gross negligence or willful
misconduct. Nothing in this Section 6 shall be deemed an authorization for Debtor to take any action that it is otherwise expressly
prohibited from undertaking by way of other provision of this Agreement.

7.
Default and Remedies.

 

7.1.
Default. Debtor shall be deemed in default under this Agreement upon the occurrence of an Event of Default.

 

7.2.
Remedies. Upon the occurrence of any such Event of Default, Secured Party shall have the rights of a secured creditor under
the UCC, all rights granted by this Agreement and by law, including, without limiting the foregoing, (a) the right to require
Debtor to assemble the Collateral and make it available to Secured Party at a place to be designated by Secured Party, and (b)
the right to take possession of the Collateral, and for that purpose Secured Party may enter upon premises on which the Collateral
may be situated and remove the Collateral therefrom. Debtor hereby agrees that fifteen (15) days’ notice of a public sale
of any Collateral or notice of the date after which a private sale of any Collateral may take place is reasonable. In addition,
Debtor waives any and all rights that it may have to a judicial hearing in advance of the enforcement of any of Secured Party’s
rights and remedies hereunder, including, without limitation, Secured Party’s right following an Event of Default to take
immediate possession of Collateral and to exercise Secured Party’s rights and remedies with respect thereto. Secured Party
may also have a receiver appointed to take charge of all or any portion of the Collateral and to exercise all rights of Secured
Party under this Agreement. Secured Party may exercise any of its rights under this Section 7.2 without demand or notice of any
kind. The remedies in this Agreement, including without limitation this Section 7.2, are in addition to, not in limitation of,
any other right, power, privilege, or remedy, either in law, in equity, or otherwise, to which Secured Party may be entitled.
No failure or delay on the part of Secured Party in exercising any right, power, or remedy will operate as a waiver thereof, nor
will any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right
hereunder. All of Secured Party’s rights and remedies, whether evidenced by this Agreement or by any other agreement, instrument
or document shall be cumulative and may be exercised singularly or concurrently.

 

7.3.
Standards for Exercising Rights and Remedies. To the extent that applicable law imposes duties on Secured Party to exercise
remedies in a commercially reasonable manner, Debtor acknowledges and agrees that it is not commercially unreasonable for Secured
Party (a) to fail to incur expenses reasonably deemed significant by Secured Party to prepare Collateral for disposition, (b)
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, (c) to fail to exercise collection remedies against account debtors or other persons obligated on Collateral or to fail to
remove liens or encumbrances on or any adverse claims against Collateral, (d) 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,
(e) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral
is of a specialized nature, (f) to contact other persons, whether or not in the same business as Debtor, for expressions of interest
in acquiring all or any portion of the Collateral, (g) to hire one or more professional auctioneers to assist in the disposition
of Collateral, whether or not the Collateral is of a specialized nature, (h) 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 capability of doing
so, or that match buyers and sellers of assets, (i) to dispose of assets in wholesale rather than retail markets, (j) to disclaim
disposition warranties, (k) to purchase insurance or credit enhancements to insure Secured Party against risks of loss, collection
or disposition of Collateral or to provide to Secured Party a guaranteed return from the collection or disposition of Collateral,
or (l) to the extent deemed appropriate by Secured Party, to obtain the services of other brokers, investment bankers, consultants
and other professionals to assist Secured Party in the collection or disposition of any of the Collateral. Debtor acknowledges
that the purpose of this Section is to provide non-exhaustive indications of what actions or omissions by Secured Party would
fulfill Secured Party’s duties under the UCC in Secured Party’s exercise of remedies against the Collateral and that
other actions or omissions by Secured Party shall not be deemed to fail to fulfill such duties solely on account of not being
indicated in this Section. Without limitation upon the foregoing, nothing contained in this Section shall be construed to grant
any rights to Debtor or to impose any duties on Secured Party that would not have been granted or imposed by this Agreement or
by applicable law in the absence of this Section.

7.4.
Marshalling. Secured Party shall not be required to marshal any present or future Collateral for, or other assurances of
payment of, the Obligations or to resort to such Collateral or other assurances of payment in any particular order, and all of
its rights and remedies hereunder and in respect of such Collateral and other assurances of payment shall be cumulative and in
addition to all other rights and remedies, however existing or arising. To the extent that it lawfully may, Debtor hereby agrees
that it will not invoke any law relating to the marshalling of Collateral which might cause delay in or impede the enforcement
of Secured Party’s rights and remedies under this Agreement or under any other instrument creating or evidencing any of
the Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or payment
thereof is otherwise assured, and, to the extent that it lawfully may, Debtor hereby irrevocably waives the benefits of all such
laws.

 

7.5.
Application of Collateral Proceeds. The proceeds and/or avails of the Collateral, or any part thereof, and the proceeds
and the avails of any remedy hereunder (as well as any other amounts of any kind held by Secured Party at the time of, or received
by Secured Party after, the occurrence of an Event of Default) shall be paid to and applied as follows:

 

(a)
First, to the payment of reasonable costs and expenses, including all amounts expended to preserve the value of the Collateral,
of foreclosure or suit, if any, and of such sale and the exercise of any other rights or remedies, and of all proper fees, expenses,
liability and advances, including reasonable legal expenses and attorneys’ fees, incurred or made hereunder by Secured Party;

 

(b)
Second, to the payment to Secured Party of the amount then owing or unpaid on the Note (to be applied first to accrued interest
and fees and second to outstanding principal) and all amounts owed under any of the other Transaction Documents or other documents
included within the Obligations; and

 

(c)
Third, to the payment of the surplus, if any, to Debtor, its successors and assigns, or to whosoever may be lawfully entitled
to receive the same.

 

In
the absence of final payment and satisfaction in full of all of the Obligations, Debtor shall remain liable for any deficiency.

 

8.
Miscellaneous.

 

8.1.
Notices. Any notice required or permitted hereunder shall be given in the manner provided in the subsection titled “Notices”
in the Purchase Agreement, the terms of which are incorporated herein by this reference.

 

    	 	5	 

    	 	 	 

    

 

8.2.
Non-waiver. No failure or delay on Secured Party’s part in exercising any right hereunder shall operate as a waiver
thereof or of any other right nor shall any single or partial exercise of any such right preclude any other further exercise thereof
or of any other right.

 

8.3.
Amendments and Waivers. This Agreement may not be amended or modified, nor may any of its terms be waived, except by written
instruments signed by Debtor and Secured Party. Each waiver or consent under any provision hereof shall be effective only in the

8.5.
Cumulative Rights, etc. The rights, powers and remedies of Secured Party under this Agreement shall be in addition to all
rights, powers and remedies given to Secured Party by virtue of any applicable law, rule or regulation of any governmental authority,
or the Note, all of which rights, powers, and remedies shall be cumulative and may be exercised successively or concurrently without
impairing Secured Party’s rights hereunder. Debtor waives any right to require Secured Party to proceed against any person
or entity or to exhaust any Collateral or to pursue any remedy in Secured Party’s power.

 

8.6.
Partial Invalidity. If any part of this Agreement is construed to be in violation of any law, such part shall be modified
to achieve the objective of the parties to the fullest extent permitted and the balance of this Agreement shall remain in full

hereof.

 

8.9.
Governing Law; Venue. Except as otherwise specifically set forth herein, the parties expressly agree that this Agreement
shall be governed solely by the laws of the State of Utah, without giving effect to the principles thereof regarding the conflict
of laws; provided, however, that enforcement of Secured Party’s rights and remedies against the Collateral as provided
herein will be subject to the UCC. The provisions set forth in the Purchase Agreement to determine the proper venue for any disputes
are incorporated herein by this reference.

 

8.10.
