Item 1.01. Entry into a Material Definitive Agreement.

Amendment No. 4 to Securities Purchase Agreement and Pledge Agreement

As previously disclosed, Profusa, Inc., a Delaware corporation (the

“Company”)entered into the (A) the Securities Purchase Agreement, dated as of February 11, 2025 (as previously amended,

the “Purchase Agreement”), by and among the Company, Ascent Partners Fund LLC, a Delaware limited liability company (“Ascent”),

the other purchasers from time to time party thereto (the “Purchasers”), and Ascent, as collateral agent for the purchaser

parties (the “Collateral Agent”), and (B) that certain Pledge Agreement, dated as of July 11, 2025 (as previously amended,

the “Pledge Agreement”), among the Company, Ben Hwang, William McMillan, Northview Sponsor I, LLC, and the Collateral Agent.

On April 2, 2026, Profusa, Inc., a Delaware corporation (the “Company”),

entered into Amendment No. 4 (“Amendment No. 4”) to the Purchase Agreement and Pledge Agreement. Pursuant to Amendment No.

4, the Company may request to sell additional convertible promissory notes (the “Additional Notes”) having an aggregate principal

amount not to exceed $12,222,222 and for a purchase price that reflects at least a 10% original issue discount, by delivering to the Collateral

Agent a notice specifying the aggregate initial principal amount requested, the purchase price and the proposed additional closing date.

Amendment No. 4 also amends the Pledge Agreement to, among other things,

replace the definition of “Release Condition” in Section 7.10 of the Pledge Agreement to mean payment in full, whether in

cash or by conversion, of $1,666,666.66 in aggregate principal amount of Notes issued in the Additional Closings expected to occur on

and shortly following the effective date of Amendment No. 4 (the “Amendment Effective Date”).

Additionally, the Company and Ascent acknowledged that any mandatory

prepayment amounts received by Ascent pursuant to the Notes shall first be allocated towards obligations owing in respect of the Additional

Notes to be issued on and shortly following the Amendment Effective Date, and then towards the secured convertible promissory notes issued

pursuant to the Purchase Agreement on July 11, 2025, and September 30, 2025, respectively.

As consideration for Ascent and the Collateral Agent agreeing to execute

Amendment No. 4 and to participate in the Additional Closing expected to occur on April 2, 2026, the Company agreed to issue to Ascent,

not later than five calendar days following the Amendment Effective Date, a warrant to purchase 1,111,111 shares of the Company’s

Common Stock (the “Warrant”) at an initial exercise price of $0.50 per share, in form reasonably acceptable to Ascent and

in the standard form typically used by Ascent for transactions of this type. The Warrant is required to contain provisions providing anti-dilution

protection to the holder, a fundamental transaction provision and a cashless exercise provision.

In connection with the Additional Closing occurring on April 2, 2026,

the Company issued to Ascent a senior secured convertible promissory note in the aggregate principal amount of $555,555.55 (the “Third

Tranche Note”). The Third Tranche Note matures on April 2, 2027, and accrues interest at a rate of 12% per annum. The Third Tranche

Note is convertible at the option of the holder into shares of the Company’s Common Stock at a conversion price of $0.50 per share,

subject to adjustment and a floor price. The Third Tranche Note provides for mandatory prepayments upon subsequent offerings equal to

50% of the net proceeds. Cash payments of principal under the Third Tranche Note are subject to a cash payment fee of 5%. The Third Tranche

Note is secured by the collateral described in the Purchase Agreement and the related security documents. The Third Tranche Note was issued

with original issue discount.

1

The Notes and the Warrant were offered and sold in a private placement

in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities

Act”), and Rule 506 of Regulation D promulgated thereunder. The securities have not been registered under the Securities Act and

may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.

The foregoing descriptions of Amendment No. 4, the Third Tranche

Note and the Warrant do not purport to be complete and are qualified in their entirety by reference to the full text of such

documents. A copy of the Third Tranche Note is filed as an exhibit hereto and is incorporated herein by reference. A copy of the

Warrant will be filed in an Amendment to this Current Report on Form 8-K following the issuance thereof.

Item 2.03. Creation of a Direct Financial Obligation or an Obligation

under an Off-Balance Sheet Arrangement of a Registrant.

The information set forth in Item 1.01 of this Current Report on Form

8-K regarding the Third Tranche Note is incorporated herein by reference.

Item 3.02. Unregistered Sales of Equity Securities.

The information set forth in Item 1.01 of this Current Report on Form

8-K regarding the issuance of the Third Tranche Note and the Warrant is incorporated herein by reference. The Third Tranche Note is convertible

into shares of the Company’s Common Stock and the Warrant is exercisable for shares of the Company’s Common Stock, in each

case as described in Item 1.01 above. The issuance of the Third Tranche Note and the Warrant, and the shares of Common Stock issuable

upon conversion or exercise thereof, were not registered under the Securities Act, in reliance on the exemption from registration provided

by Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder.

Item 8.01. Other Events.

Letter of Intent Relating to Proposed Acquisition of Bio Insights

PanOmics Assets

On March 31, 2026, the Company entered into a non-binding letter of

intent (as amended and restated on April 3, 2026, the “LOI”) with Bio Insights LLC (“Bio Insights”), pursuant

to which the Company proposes to acquire certain assets of Bio Insights, including the PanOmics assay and related know-how (the “PanOmics

Assets”), for aggregate consideration of $30,000,000 (the “Proposed Transaction”). The Proposed Transaction is conditioned

upon: (i) the negotiation and execution of a definitive asset acquisition agreement; (ii) the satisfaction of customary closing conditions;

and (iii) the receipt of all required stockholder approvals. The LOI is non-binding except with respect to certain provisions relating

to confidentiality, exclusivity, termination and governing law.

Profusa believes that the acquisition of the Panomic DX next-generation

sequencing (NGS) assets introduces a near-term revenue opportunity aligned with recent CMS reimbursement guidance requiring NGS testing

in oncology. Panomic DX offers the potential for immediate commercial traction and reimbursement-backed cash flow potential. Moreover,

the Company believes that the combination of real-time biochemical monitoring and genomic diagnostics will strengthen the Company’s

ability to deliver a fully integrated oncology solution. The PanOmics Assets enable a marker panel that has been designed for broad utilization

across several important cancers as well as common metabolic disease states. include pancreatic cancer, fatty liver cancer, Esophageal

Cancer and Thyroid Cancer. The PanOmics marker panel is designed to identify sequence variations and copy number expression conferring

hereditary risk, profile somatic tumor mutations to guide therapeutic selection, support liquid biopsy monitoring via circulating tumor

DNA, and predict malignant progression in patients.

2

The Centers for Medicare and Medicaid Services (“CMS”)

recently announced that next-generation sequencing testing is necessary for reimbursement in the relevant oncology indications —

a policy determination that the Company believes substantially de-risks the commercial pathway for PanOmic DX and validates the strategic

logic of the planned asset acquisition. With reimbursement now tied to the use of next-generation sequencing, PanOmic DX is positioned

to generate meaningful near-term revenue while LumeeOxygen advances through clinical validation, thereby meaningfully diversifying Profusa’s

commercial profile at precisely the right moment.

Under the terms of the LOI, the aggregate purchase price of $30,000,000

is to be satisfied entirely through the issuance of equity securities of the Company, consisting of: (a) 460,000 shares of Common Stock

(limited to 19.99% of total shares outstanding) to be issued at the closing; and (b) shares of a new series of preferred stock of the

Company (the “Preferred Stock”), which shall be non-voting and convertible into 59,540,000 shares of Common Stock (the “Conversion

Shares”), with such conversion right exercisable one year following the date of issuance of the Preferred Stock. The number of shares

to be issued will be calculated based on the closing transaction price reported by Nasdaq on the trading day preceding the closing. The

Conversion Shares will be subject to registration rights and a Lock-Up Agreement to be executed by Bio Insights in the form attached as

an exhibit to the LOI (the “Lock-Up Agreement”). Pursuant to the Lock-Up Agreement, the Conversion Shares will be subject

to a seven-year lock-up period with annual releases of one-seventh of the Conversion Shares each year, subject to a carve-out permitting

Bio Insights to sell such number of Conversion Shares as may be necessary to fund tax liabilities arising from the transaction.

In connection with the Proposed Transaction, Bio Insights will be entitled

to receive royalty payments equal to 3% of net revenue, payable annually following the completion of audited full-year financial statements.

The Company has agreed to make best efforts to conclude an equity financing of $10,000,000 contemporaneously with or within 30 days following

the closing of the Proposed Transaction, and to allocate a minimum of 15% of the net proceeds of such financing and future financings,

up to $2,000,000 in aggregate, for consulting work and reagent costs related to the PanOmics assay’s analytical and clinical validation

and capital equipment needs.

In connection with the closing of the Proposed Transaction, the Company

will issue to management shares equal to 12% of the fully diluted shares outstanding immediately following the transaction and related

fundraising, for retention of the Company’s Chief Executive Officer and Chief Financial Officer, reduced by any RSUs or options

issued to management between the date of the LOI and the announcement of the Proposed Transaction. All existing employment and severance

arrangements for the Company’s CEO and CFO are to be reviewed by Bio Insights prior to execution of the definitive documentation,

with any changes or amendments to be mutually agreed to ensure proper retention incentives are in place for a period of two years.

The closing of the Proposed Transaction is subject to certain conditions,

including, among others: (a) the accuracy of representations and warranties of Bio Insights; (b) compliance with covenants; (c) the absence

of any material adverse effect; (d) receipt of all governmental and third-party consents; (e) completion of legal, financial, tax and

commercial due diligence to the Company’s satisfaction; (f) physical delivery of clinical samples to the Company’s designated

facility; and (g) receipt of a legal opinion from Bio Insights’ counsel. The Company is required to hold a shareholder meeting for

the purpose of voting upon the issuance of the securities contemplated by the Proposed Transaction prior to June 30, 2026, and to use

its reasonable best efforts to solicit proxies in favor of such approval.

3

Bio Insights shall have the right to nominate one independent Board

member for consideration by stockholders at the next regularly scheduled annual meeting of stockholders of Profusa. Such nominee shall

be required to be presented to stockholders unless he/she is approved by a majority of the members of the Nominating and Corporate Governance

Committee and a majority of the members of the Profusa Board of Directors. It is contemplated that such nominee would replace a Board

member whose term is expiring. Profusa shall not be required to enlarge the Board to accommodate the new nominee.

In connection therewith, Bio Insights is required to execute a Voting

Agreement in the form attached as an exhibit to the LOI (the “Voting Agreement”), pursuant to which Bio Insights agrees to

vote all shares of Common Stock beneficially owned by it in favor of stockholder proposals recommended by the board of directors of the

Company.

During the term of the LOI (the “Exclusivity Period”),

Bio Insights and its affiliates and representatives are prohibited from soliciting, initiating or encouraging any inquiry or proposal,

engaging in discussions or negotiations, or providing non-public information to any third party relating to any acquisition, sale of equity

or assets, or similar transaction. The LOI will terminate automatically upon the earlier of the execution of definitive documentation

or 5:00 p.m., Eastern time, on May 1, 2026, unless extended by mutual agreement. The parties have agreed to use good faith, commercially

reasonable efforts to negotiate and execute a definitive agreement within 30 days of the date of the LOI, subject to automatic extension

for an additional 30 days if the parties are actively negotiating in good faith.

The foregoing description of the LOI does not purport to be complete

and is qualified in its entirety by reference to the full text of the LOI, a copy of which is filed as Exhibit 99.1 hereto and is incorporated

herein by reference.

On April 6, 2026, the Company issued a press release announcing its

entry into the LOI. A copy of the press release is filed as Exhibit 99.2 hereto and is incorporated herein by reference.

such principal repayment is a regularly scheduled Amortization Payment set forth on Schedule 2, any remaining Minimum Interest

Amount shall due and be payable (until such remaining Minimum Interest Amount shall be fully paid) in the amounts and on the dates on

which accrued interest would have been due if such Amortization Payments had not been made and interest had accrued on such principal.

Subject to satisfaction (or due waiver by the Holder) of the Equity Payment Conditions on the date of such payment, interest (including

any remaining Minimum Interest Amount) may be paid in Common Stock in the Company’s discretion at the Amortization Price. Upon an

Event of Default, the interest rate set forth hereunder shall increase as provided in clause (e) below. The Minimum Interest Amount

is intended to compensate the Holder for a lesser profit in case of early repayment and for the internal and external work and expenditure

of time and money involved in the evaluation and preparation of the Transaction Documents and the consummation of the transactions contemplated

thereunder. The Minimum Interest Amount is not to be construed to cover or be applied against any indemnity or any out-of-pocket fees,

costs or expenses incurred in any action to collect any Obligation or to foreclose any Lien securing the same. This provision shall not

affect or limit the Holder’s rights or remedies with respect to any Event of Default.

e) Default Rate. Immediately

on and after the occurrence of any Event of Default, without need for notice or demand all of which are waived, interest on this Note

shall, in whole, automatically and without the need for any notice, demand or any other action by the Collateral Agent or the Holder all

of which are hereby waived, accrue and be owed daily at an increased interest rate equal to the lower of the Default Rate or the maximum

rate permitted under applicable Regulations. If an Event of Default (after giving effect to notice periods and grace periods) occurs,

the Default Rate shall become effective as of the date the Default that because such Event of Default first occurred, without consideration

for any notice provision or grace period.

f) Late Fee. The Company

shall pay a late fee (each a “Late Fee”) on any Obligation that is not paid when due (after taking into account applicable

grace periods set forth in Section 7(a)(i) hereof), in an amount equal to ten percent (10%) of such payment, to the Person owed such Obligation.

This Late Fee shall be due and payable immediately upon such failure. It is intended to cover the inconvenience and additional internal,

administrative and other fees, costs and expenses involved in processing delinquent payments and is not to be construed to cover or be

applied against any indemnity or any out-of-pocket fees, costs or expenses incurred in any action to collect any Obligation or to foreclose

any Lien securing the same. This provision shall not affect or limit the Holder’s rights or remedies with respect to any Event of

Default. This obligation to pay a Late Fee is a separate obligation and, once it has arisen hereunder, a failure to pay such Late Fee

will not be cured implicitly by any waiver of any Event of Default or similar event that may have caused the payment that gave rise to

such Late Fee.

- 16 -

g) Cash Payment Fee. The

Company shall pay a cash payment fee (each a “Cash Payment Fee”) in an amount equal to five percent (5%) of the amount

of any repayment of the principal amount of this Note that is made in cash at any time when (i) the Company shall not have received a

notice from the Holder or the Collateral Agent that an Event of Default exists, or (ii) the Company shall have received such a notice

and such Event of Default shall have been cured to the satisfaction of the Holder. This Cash Payment Fee shall be due and payable together

with such repayment and is intended to cover any loss in revenues resulting from such repayment being made in cash instead of using Common

Stock, as well as other internal costs and expenses and is not to be construed to cover or be applied against any indemnity or any out-of-pocket

fees, costs or expenses incurred in any action to collect any Obligation or to foreclose any Lien securing the same. The Cash Payment

Fee shall not be applicable to the payment of any Mandatory Prepayment Amount. This provision shall not affect or limit the Holder’s

rights or remedies with respect to any Event of Default. This obligation to pay a Cash Payment Fee is a separate obligation hereunder

and, once arisen, shall be owed regardless of whether such payment is later returned, reversed, forgiven, waived or voided.

h) Calculations and Payment

Provisions. All payments made to the Holder, the Collateral Agent and their Purchaser Parties under any Transaction Document, except

as otherwise expressly provided in any Transaction Document, shall be made in cash, which shall mean in immediately available dollars

and without set off or counterclaim. Interest and fees owing to any of them shall be calculated on the basis of a 360-day year consisting

of twelve thirty (30)-day periods, for the actual number of days occurring, in whole or in part, in the applicable period. The Holder

(or, for payments owing to it, the Collateral Agent) shall have the option to refuse or accept, in their sole discretion, any payment

to the Collateral Agent, the Holder or their Purchaser Parties attempted to be made without a required notice, without a required Optional

Prepayment Amount, a Minimum Interest Amount or a required fee. The Holder (or, for payments owing to the Collateral Agent, the Collateral

Agent) may, in its sole discretion, apply or recharacterize any payment made under any Transaction Document to the payment of any outstanding

Obligation, regardless of the intended characterization thereof by any Company Party, including by recharacterizing a payment of principal

made to a payment of an Optional Prepayment Amount, a Minimum Interest Amount or a required fee, even if this characterization results

in a smaller payment of principal. The Company hereby irrevocably waives the right to direct the application of any payment (or, after

any Event of Default, any proceeds of Collateral) to any Obligation. Whenever any payment under any Transaction Document shall be stated

to be due on a day other than a Business Day, such payment shall be due on the next succeeding Business Day, including for purposes of

the calculation of interest and fees. Any payment of any Obligation received by the Holder, the Collateral Agent or any Purchaser Party

after 3 p.m. on any day shall be deemed received on the next Business Day. Each determination by the Holder (or, for payments owing to

it, the Collateral Agent) of an amount of interest or fee due hereunder shall be conclusive and binding for all purposes, absent manifest

error.

Section

3. Registration of Transfers and Exchanges

a) Different Denominations.

This Note is exchangeable for an equal aggregate principal amount of Notes of different authorized denominations, as requested by

the Holder surrendering the same. No service charge will be payable for such registration of transfer or exchange.

b) Investment Representations.

This Note has been issued subject to certain investment representations of the original Holder and may be transferred or exchanged

only in compliance with applicable federal and state securities Regulations.

- 17 -

c) Reliance on Note Register.

The Company shall maintain in its records a list of the Holders and of registration and transfers of the Note (the “Note

Register”). The initial Holder is listed herein. Any Holder may later notify in writing the Company of an assignment or transfer

and the Company shall notify such transfer in the Note Register. Failure by the Company to duly notify such transfer in the Note Register

shall not affect the validity of such assignment or transfer. Nevertheless, if the Company has not received notice of any transfer of

this Note, the Company and any agent of the Company may treat the Person in whose name this Note is duly registered as the owner hereof

for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Note is overdue. Upon request

by the Holder, the Company shall immediately execute and deliver to such Holder replacement Note or Notes, which may involve executing

multiple Notes with split amounts to reflect partial assignments. Promptly upon receipt of such replacement Note or Notes, such Holder

shall deliver the original Note back to the Company or, if the original Note is lost or stolen, provide an affidavit to the Company to

that effect.

Section

4. Conversion

a) Voluntary Conversion.

At any time after the Original Issue Date, all Obligations with respect to this Note shall be convertible, in whole or in part, into shares

of Common Stock at the option of the Holder, in its sole discretion, at any time and from time to time (subject to the conversion limitations

set forth in Section 4(d)). The Holder shall effect conversions by delivering to the Company a Notice of Conversion, the form of

which is attached hereto as Annex A (each, a “Notice of Conversion”), specifying therein the amount of such

Obligations to be converted and the date on which such conversion shall be effected (such date, the “Conversion Date”).

If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion is

deemed delivered hereunder. No ink-original Notice of Conversion shall be required, nor shall any medallion guarantee (or other type of

guarantee or notarization) of any Notice of Conversion form be required. To effect conversions hereunder, the Holder shall not be required

to physically surrender this Note to the Company unless the entire principal amount of this Note, plus all accrued and unpaid interest

thereon, has been converted. Conversions hereunder shall have the effect of lowering the outstanding principal amount of this Note by

an amount equal to the applicable conversion. The Holder and the Company shall maintain a Conversion Schedule, containing at a minimum

the information shown on Schedule 1, and showing historically, among other things, the principal amounts converted and the date

of such conversions. The Company may deliver an objection to any Notice of Conversion within one (1) Business Day of delivery of such

Notice of Conversion. In the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in

the absence of manifest error.

b) Conversion Price. Subject

to the other provisions of this Note, the conversion price in effect on any Conversion Date (the “Conversion Price”) shall

be equal to the lower of (i) the amount set forth in clause (b)(i) of the definition of “Amortization Price,” and (ii) ninety-five

percent (95%) of the lowest VWAP for the Common Stock during the ten (10) consecutive Trading Days immediately preceding the applicable

Conversion Date (such lower amount, the “Alternate Conversion Price”); provided, that in no event shall the Conversion Price

be less than the Floor Price.

c) Mechanics of Conversion.

i. Conversion Shares

Issuable Upon Conversion of Principal Amount. The number of Conversion Shares issuable upon a conversion hereunder shall be determined

by the quotient obtained by dividing (x) the outstanding principal amount and interest of this Note to be converted by (y) the Conversion

Price.

ii. Delivery of Certificate

Upon Conversion. Not later than one (1) Trading Day after each Conversion Date (the “Share Delivery Date”), the

Company shall deliver, or cause to be delivered, to the Holder a certificate or certificates representing the Conversion Shares which,

on or after the date on which such Conversion Shares are eligible to be sold under Rule 144 without the need for current public information

and the Company has received an opinion of counsel to such effect, which such opinion must be acceptable to the Holder in its sole and

absolute discretion (which opinion the Company shall be responsible for obtaining at its sole cost and expense) shall be free of restrictive

legends and trading restrictions, representing the number of Conversion Shares being acquired upon the conversion of this Note. Each certificate

required to be delivered by the Company under this Section 4(c) shall be delivered electronically through the Depository Trust

Company or another established clearing corporation performing similar functions. If the Conversion Date is prior to the date on which

such Conversion Shares are eligible to be sold under Rule 144 without the need for current public information, or there is no registration

statement in effect covering the Conversion Shares, the Conversion Shares shall bear a restrictive legend in the following form, as appropriate:

“THE ISSUANCE AND SALE OF THE SECURITIES

REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES

REGULATIONS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION

STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL (WHICH COUNSEL SHALL BE SELECTED

BY THE HOLDER), IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE

144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT

OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.”

- 18 -

Notwithstanding the foregoing, commencing

on such date that the Conversion Shares are eligible for sale under Rule 144 subject to current public information requirements, the Company,

upon written request and at the sole cost and expense of the Company, shall obtain a legal opinion that is acceptable to the Holder in

its sole and absolute discretion, to allow for such sales under Rule 144.

iii. Reservation

of Conversion Shares. The Company covenants that it will at all times reserve and keep available out of its authorized and unissued

shares of Common Stock a number of shares of Common Stock at least equal the Reserve Amount for the sole purpose of issuance upon conversion

of this Note and payment of interest on this Note, each as herein provided, free from preemptive rights or any other actual contingent

purchase rights of Persons other than the Holder (and the other holders of the Purchase Agreement Notes). The Company covenants that all

shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and nonassessable.

The Company shall calculate and readjust the Reserve Amount on the first Business Day of each month so long as any Purchased Security

remains outstanding.

iv. Fractional Shares.

No fractional shares or scrip representing fractional shares shall be issued upon the conversion of this Note. As to any fraction of a

share which the Holder would otherwise be entitled to purchase upon such conversion, the Company shall at its election, either pay a cash

adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Conversion Price or round up to the

next whole share.

v. Transfer Taxes

and Expenses. The issuance of certificates for shares of the Common Stock on conversion of this Note shall be made without charge

to the Holder hereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificates,

provided, that, the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the

issuance and delivery of any such certificate upon conversion in a name other than that of the Holder of this Note so converted and the

Company shall not be required to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof

shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been

paid. The Company shall pay all Transfer Agent fees required for same-day processing of any Notice of Conversion

vi. Failure to Deliver

Certificates. If, in the case of any Notice of Conversion, such certificate or certificates are not delivered to or as directed by

the applicable Holder by the Share Delivery Date, the Holder shall be entitled to elect by written notice to the Company at any time on

or before its receipt of such certificate or certificates, to rescind such Conversion, in which event the Company shall promptly return

to the Holder any original Note delivered to the Company and the Holder shall promptly return to the Company the Common Stock certificates

issued to the Holder pursuant to the rescinded Notice of Conversion.

vii. Obligation Absolute;

Partial Liquidated Damages. The Company’s obligations to issue and deliver the Conversion Shares upon conversion of this Note

in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the

same, the existence of any Default or Event of Default, any waiver or consent with respect to any provision hereof, the recovery of any

judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or

any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation

of Regulations by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation

of the Company to the Holder in connection with the issuance of such Conversion Shares; provided, that such delivery shall not

operate as a waiver by the Company of any such action the Company may have against the Holder. In the event the Holder of this Note shall

elect to convert any or all of the outstanding principal or interest amount hereof, the Company may not refuse conversion based on any

claim that the Holder or anyone associated or affiliated with the Holder has been engaged in any violation of Regulation, Contractual

Obligation or for any other reason, unless an injunction from a court, on notice to Holder, restraining and or enjoining conversion of

all or part of this Note shall have been sought. If the injunction is not granted, the Company shall promptly comply with all conversion

obligations herein. If the injunction is obtained, the Company must post a surety bond for the benefit of the Holder in the amount of

one hundred fifty percent (150%) of the outstanding principal amount of this Note, which is subject to the injunction, which bond shall

remain in effect until the completion of arbitration/litigation of the underlying dispute and the proceeds of which shall be payable to

the Holder to the extent it obtains judgment. In the absence of seeking such injunction, the Company shall issue Conversion Shares (or,

where applicable and required hereunder, cash), upon a properly noticed conversion. If the Company fails for any reason to deliver to

the Holder such certificate or certificates pursuant to Section 4(c)(ii) by the Share Delivery Date, the Company shall pay to the

Holder, in cash, as liquidated damages and not as a penalty, $1,000 per Trading Day for each Trading Day after such Share Delivery Date

until such certificates are delivered or Holder rescinds such conversion. Nothing herein shall limit a Holder’s right to pursue

actual damages or declare an Event of Default pursuant to Section 7 for the Company’s failure to deliver Conversion Shares

within the period specified herein and the Holder shall have the right to pursue all remedies available to it hereunder, at law or in

equity including a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit the Holder

from seeking to enforce damages pursuant to any other Section hereof or under applicable Regulation.

- 19 -

viii. Compensation

for Buy-In on Failure to Timely Deliver Certificates Upon Conversion. In addition to any other rights available to the Holder, if

the Company fails for any reason to deliver to the Holder such certificate or certificates by the Share Delivery Date pursuant to Section

4(c)(ii), and if after such Share Delivery Date the Holder is required by its brokerage firm to purchase (in an open market transaction

or otherwise), or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by

the Holder of the Conversion Shares which the Holder was entitled to receive upon the conversion relating to such Share Delivery Date

(a “Buy-In”), then the Company shall (A) pay in cash to the Holder (in addition to any other remedies available to

or elected by the Holder) the amount, if any, by which (x) the Holder’s total purchase price (including any brokerage commissions)

for the Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that the Holder was entitled

to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation

was executed (including any brokerage commissions) and (B) at the option of the Holder, in its sole discretion, either reissue (if surrendered)

this Note in a principal amount equal to the principal amount of the attempted conversion (in which case such conversion shall be deemed

rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued if the Company had timely complied

with its delivery requirements under Section 4(c)(ii). For example, if the Holder purchases Common Stock having a total purchase

price of $11,000 to cover a Buy-In with respect to an attempted conversion of this Note with respect to which the actual sale price of

the Conversion Shares (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause

(A) of the immediately preceding sentence, the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company

written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the

amount of such loss. Nothing herein shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law

or in equity including a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely

deliver certificates representing shares of Common Stock upon conversion of this Note as required pursuant to the terms hereof.

ix. No Limitation

on Damages. More generally, nothing in this Section 4, including the availability of the option to convert the Note, shall

limit the Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section 7 and the Holder shall

have the right to pursue all remedies available to it hereunder, at law or in equity including a decree of specific performance and/or

injunctive relief. The exercise of any rights under this Section 4 shall not prohibit the Holder from seeking to enforce damages

pursuant to any other Section hereof or under applicable Regulation.

d) Holder’s Conversion

Limitations. The Company shall not effect any conversion of principal or interest of this Note, and the Holder shall not have the

right to convert any principal or interest of this Note, to the extent that after giving effect to the conversion set forth on the applicable

Notice of Conversion, the Holder (together with the Holder’s Affiliates, and any Persons acting as a group together with the Holder

or any of the Holder’s Affiliates, the “Attribution Parties”) would beneficially own in excess of the Beneficial

Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned

by the Holder and its Attribution Parties shall include the number of Conversion Shares issuable upon conversion of this Note with respect

to which such determination is being made, but shall exclude the number of shares of Common Stock issuable upon (i) conversion of the

remaining, unconverted principal amount of this Note beneficially owned by the Holder or any of its Attribution Parties and (ii) exercise

or conversion of the unexercised or unconverted portion of any other Securities of the Company subject to a limitation on conversion or

exercise analogous to the limitation contained herein (including any other Notes) beneficially owned by the Holder or any of its Attribution

Parties. Except as set forth in the preceding sentence, for purposes of this Section 4(d), beneficial ownership shall be calculated

in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation

contained in this Section 4(d) applies, the determination of whether this Note is convertible (in relation to other Securities

owned by the Holder together with any Attribution Parties) and of which principal amount of this Note is convertible shall be in the sole

discretion of the Holder, and the submission of a Notice of Conversion shall be deemed to be the Holder’s determination of whether

this Note may be converted (in relation to other Securities owned by the Holder together with any Attribution Parties) and which principal

amount of this Note is convertible, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction,

the Holder will be deemed to represent to the Company each time it delivers a Notice of Conversion that such Notice of Conversion has

not violated the restrictions set forth in this paragraph and the Company shall have no obligation to verify or confirm the accuracy of

such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section

13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 4(d), in determining

the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as stated in

the most recent of the following: (i) the Company’s most recent periodic or annual report filed with the SEC, as the case may be,

(ii) a more recent public announcement by the Company, or (iii) a more recent written notice by the Company or the Company’s transfer

agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of the Holder, the Company shall

within two (2) Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any

case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of Securities

of the Company, including this Note, by the Holder or its Attribution Parties since the date as of which such number of outstanding shares

of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common

Stock outstanding immediately after giving effect to the issuance of all Conversion Shares to be held by the Holder. The Holder, upon

not less than sixty-one (61) days’ prior notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions

of this Section 4(d); provided, that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares

of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon conversion of this Note

held by the Holder. Any such increase or decrease will not be effective until the sixty-first (61st) day after such notice

is delivered to the Company. The Beneficial Ownership Limitation provisions of this paragraph shall be construed and implemented in a

manner otherwise than in strict conformity with the terms of this Section 4(d) to correct this paragraph (or any portion hereof)

which may be defective or inconsistent with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements

necessary or desirable to properly give effect to such limitation. The limitations contained in this Section 4(d) shall apply to

a successor Holder of this Note.

- 20 -

e) Exchange Cap. The Company

shall not issue any shares of Common Stock upon conversion of this Note or otherwise pursuant to the terms of this Note if the issuance

of such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue upon conversion

of this Note or otherwise pursuant to the terms of this Note without breaching the Company’s obligations under the rules or regulations

of the Principal Trading Market for the Common Stock (the number of shares which may be issued without violating such rules and regulations,

the “Exchange Cap”), except that such limitation shall not apply in the event that the Company (i) obtains the approval

of its stockholders as required by the applicable rules of such Principal Trading Market for issuances of shares of Common Stock in excess

of such amount or (ii) obtains a written opinion from outside counsel to the Company that such approval is not required, which opinion

shall be in form and substance reasonably satisfactory to the Holder. Until such approval or such written opinion is obtained, the Holder

shall not be issued in the aggregate, upon conversion of this Note or otherwise pursuant to the terms of this Note, shares of Common Stock

in an amount greater than the product of (A) the Exchange Cap as of the proposed date of issuance for such shares multiplied by (B) the

quotient of (1) the aggregate original Principal Amount of this Note when issued to the applicable Purchaser pursuant to the Purchase

Agreement divided by (2) the aggregate original Principal Amount of all Purchase Agreement Notes when issued (the “Exchange Cap

Allocation”). In the event that the Holder sells or otherwise transfer any portion of this Note, the transferee shall be allocated

a pro rata portion of the Holder’s Exchange Cap Allocation with respect to such portion of this Note so transferred, and the restrictions

of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation so allocated to such transferee.

Upon conversion in full of any holder of any Purchase Agreement Note, the difference (if any) between such holder’s “exchange

cap allocation” (under and as defined in such Purchase Agreement Note) and the number of shares of Common Stock actually issued

to such holder upon such holder’s conversion in full of any Purchase Agreement Note shall be allocated to the respective Exchange

Cap Allocations of the remaining holders of such Purchase Agreement Notes (including the Holder) on a pro rata basis in proportion to

the shares of Common Stock underlying such Purchase Agreement Notes then held by each such holder. In the event that the Company is prohibited

from issuing any shares of Common Stock pursuant to this Section 4(e)(the “Exchange Cap Shares”) to the Holder,

the Company shall pay cash to the Holder in exchange for the redemption of such portions of this Note that are not convertible into such

Exchange Cap Shares at a price equal to the sum of (A) the product of (1) such number of Exchange Cap Shares and (2) the Closing Sale

Price on the Trading Day immediately preceding the date the Holder delivers the applicable Notice of Conversion with respect to such Exchange

Cap Shares to the Company, and (B) to the extent the Holder purchases (in an open market transaction or otherwise) shares of Common Stock

to deliver in satisfaction of a sale by the Holder of Exchange Cap Shares, brokerage commissions, if any, of the Holder incurred in connection

therewith.

Section

5. Certain Adjustments

a) Stock Dividends and Stock

Splits. If the Company, at any time while this Note is outstanding: (i) pays a stock dividend or otherwise makes a Restricted Payment

payable in shares of Common Stock on shares of Common Stock or any Stock Equivalents (which, for avoidance of doubt, shall not include

any shares of Common Stock issued by the Company upon conversion of, or payment of interest on, this Note), (ii) subdivides outstanding

shares of Common Stock into a larger number of shares, (iii) combines (including by way of a reverse stock split) outstanding shares of

Common Stock into a smaller number of shares or (iv) issues, in the event of a reclassification of shares of the Common Stock, any shares

of capital stock of the Company, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number

of shares of Common Stock (excluding any treasury shares of the Company) outstanding immediately before such event, and of which the denominator

shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section

5(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend

or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

- 21 -

b) Change in Option Price

or Rate of Conversion. If the purchase or exercise price provided for in any options to purchase Common Stock, the additional consideration,

if any, payable upon the issue, conversion, exercise or exchange of any Stock Equivalents into Common Stock, or the rate at which any

Stock Equivalents are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time (other

than any change to the Conversion Price in this Note or any changes to the exercise price in the Warrants), the Conversion Price in effect

at the time of such increase or decrease shall be adjusted to account proportionately, for such increase or decrease. For purposes of

this Section 5(b), if the terms of any option or Stock Equivalents are increased or decreased in the manner described in the immediately

preceding sentence, then such option or Stock Equivalents and the shares of Common Stock deemed issuable upon exercise, conversion or

exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section

5(b) shall be made to the Conversion Price if such adjustment would result in an increase to the Conversion Price.

c) Subsequent Equity Sales.

If any Company Party or any Subsidiary thereof, at any time while any Obligation is outstanding or the Holder has not yet received any

Conversion Shares in connection with a conversion, shall sell or grant any option to purchase, or sell or grant any right to reprice,

or otherwise dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any shares of Common

Stock or Stock Equivalents convertible or exchangeable into Common Stock, in each case other than as an Exempt Issuance, at an effective

price per share that, after giving effect to any other adjustment provided in this Note, is less than the Conversion Price then in effect

(such lower price, the “Base Share Price” and such issuances collectively, a “Dilutive Issuance”)

then, simultaneously with the consummation of each Dilutive Issuance the Conversion Price shall be reduced and only reduced to equal the

Base Share Price. For the avoidance of doubt, it is understood and agreed that if a holder of the shares of Common Stock or Stock Equivalents

so issued shall, at any time after the issuance, whether by operation of purchase price adjustments, reset provisions, floating conversion,

exercise or exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance,

be entitled to receive shares of Common Stock at an effective price per share that is less than the Conversion Price, such issuance shall

be deemed to have occurred for less than the Conversion Price on such date of the Dilutive Issuance at such effective price. Such adjustment

shall be made whenever such shares of Common Stock or Stock Equivalents are issued. No later than 8:00 am on the Trading Day following

the issuance or deemed issuance of any shares of Common Stock or Stock Equivalents subject to this Section 5(c), the Company shall

(i) notify the Holder, in writing, indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion

price and other pricing terms (such notice, the “Dilutive Issuance Notice”) and (ii) publicly disclose the transaction

resulting in such issuance or deemed issuance in a filing with the SEC. For purposes of clarification, whether or not the Company provides

a Dilutive Issuance Notice pursuant to this Section 5(c), upon the occurrence of any Dilutive Issuance, the Holder is entitled

to receive a number of Conversion Shares based upon the Base Share Price regardless of whether the Holder accurately refers to the Base

Share Price in the Notice of Conversion.

d) Pro Rata Distributions.

While this Note is outstanding, the Company shall not declare or make any Restricted Payment (or rights to receive Restricted Payments).

In the event that the Note is repaid at the time of such Restricted Payment, the Holder shall not be entitled to participate in such Restricted

Payment. If the Holder and the Company mutually agree, and the Note is not repaid at the time of such Restricted Payment, then the Holder

shall be entitled to participate in such Restricted Payment to the same extent that the Holder would have participated therein if the

Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Note (without regard to any limitations

on exercise hereof, including the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Restricted

Payment, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the

participation in such Restricted Payment (provided, that to the extent that the Holder’s right to participate in any such

Restricted Payment would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to

participate in such Restricted Payment to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such

Restricted Payment to such extent) and the portion of such Restricted Payment shall be held in abeyance for the benefit of the Holder

until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

- 22 -

e) Effect of Fundamental Transactions.

Upon the occurrence of any Fundamental Transaction, the Holder, upon any subsequent conversion of this Note, shall have the right to receive,

for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction

(without regard to any limitation in Section 4(c) on the conversion of this Note), any consideration receivable as a result of

such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Note is convertible (or holder of any

equity Securities of any Company Party) immediately prior to such Fundamental Transaction (without regard to any limitation in Section

4(c) on the conversion of this Note) (the “Alternate Consideration”), including shares of Common Stock of any successor

or acquiring corporation or of the Company, in the case of a merger where it is the surviving entity. To the extent such Alternate Consideration

includes Securities, the Holder shall have the option to either treat the Note as converted on the date of consummation of such Fundamental

Transaction and obtain such Securities outright or adjust the Conversion Shares to include such additional Securities. For purposes of

any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration

based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the

Company Parties shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative

value of any different components of the Alternate Consideration. In a Fundamental Transaction where holders of Common Stock (or, as the

case may be, Securities of any Company Party) are given any choice as to the Alternate Consideration to be received in a Fundamental Transaction,

then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Note following

such Fundamental Transaction. The Company shall cause any acquiring, successor, surviving or replacement entities in any Fundamental Transaction

(the “Successor Entity”) to become a Company Party effective immediately upon the consummation of such Fundamental

Transaction and shall become a party to all Transaction Documents in the same capacity and to the same extent as the Company Party involved

in such Fundamental Transaction and, if such Fundamental Transaction involves the Company, from and after the date of such Fundamental

Transaction, the provisions of this Note and the other Transaction Documents referring to the “Company” shall, without any

further action, refer instead to the Successor Entity or to both Companies, as appropriate. In the case of a Fundamental Transaction resulting

in the Company no longer be in existence, the Successor Entity shall succeed to all obligations of the Company and may exercise every

right and power of the Company and shall assume all of the Obligations of the Company with the same effect as if such Successor Entity

had been named as the Company herein. The parties hereto shall amend all Transaction Documents (or execute new Transaction Documents,

including replacement Notes and an assumption of the Company’s Obligations) to reflect such change; provided that the failure

to amend or execute any such Transaction Document shall not render this clause (e) ineffective. For the avoidance of doubt, this

clause (e) is not intended to permit any Fundamental Transaction. The Company shall ensure that the Holder approves all drafts

of such amendments and new Transaction Documents prior to the consummation of, and as a condition to the consummation of, such Fundamental

Transaction. Without limitation, if the Fundamental Transaction involves the Company, the definition of Conversion Shares and Conversion

Price hereunder shall be adjusted to include Securities of the Successor Entity and to ensure the new Notes of the Holder convert into

Securities so as to protect the economic value of this Note, taking into account the relative values of the existing and replacement Conversion

Shares, and give the Holder upon conversion of this Note the Conversion Shares equivalent to the Conversion Shares it would have received

upon conversion of this Note prior to such Fundamental Transaction at an equivalent Conversion Price.

f) Calculations. All calculations

under this Section 5 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this

Section 5, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the

number of shares of Common Stock (excluding any treasury shares of the Company) issued and outstanding.

g) Notices to the Holder.

i. Adjustments to

Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Section 5, the Company shall

not later than 8:00 am on the Trading Day following such adjustment (i) deliver to each Holder a notice setting forth the Conversion Price

after such adjustment and setting forth a statement of all of the facts requiring such adjustment and the calculation thereof, and (ii)

publicly disclose the transaction resulting in such adjustment in a filing with the SEC. Notwithstanding anything in this Section 5

to the contrary, no adjustment pursuant to this Section 5 shall increase the Conversion Price other than proportional increases

upon the occurrence of a reverse stock split in accordance with Section 5(a). For the avoidance of doubt, the Holder will be entitled

to each such adjustment on the terms set forth in this Agreement whether or not the Company provides such notice, and the calculation

set forth in such notice shall not be binding on the Holder.

- 23 -

ii. Notice to Allow

Conversion by Holder. If (A) the Company shall declare a dividend (or any other distribution or other Restricted Payment in whatever

form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock,

(C) the Company shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or purchase any

shares of Capital Stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection

with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all

or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other Securities,

cash or property or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs

of the Company, then, in each case, the Company shall cause to be filed at each office or agency maintained for the purpose of conversion

of this Note, and shall cause to be delivered to the Holder at its last address as it shall appear upon the Note Register, at least twenty

(20) calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record

is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the

date as of which the holders of the Common Stock of record to be entitled to such dividend, distribution, Restricted Payment, redemption,

rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share

exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record

shall be entitled to exchange their shares of the Common Stock for Securities, cash or other property deliverable upon such reclassification,

consolidation, merger, sale, transfer or share exchange; provided, that the failure to deliver such notice or any defect therein

or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. The Holder shall

remain entitled to convert this Note during the 20-day period commencing on the date of such notice through the effective date of the

event triggering such notice except as may otherwise be expressly set forth herein.

Section

8. Miscellaneous

a) Notices. Any and all

notices or other communications or deliveries to be provided by the Holder hereunder, including any Notice of Conversion, shall be in

writing and delivered as set forth in Section 6.4 (Notices) of the Purchase Agreement. All notices and other communications delivered

hereunder shall be effective as provided in the Purchase Agreement.

b) Absolute Obligation.

Except as expressly provided herein, no provision of this Note shall alter or impair the obligation of the Company, which is absolute

and unconditional, to pay the principal of, liquidated damages and accrued interest, as applicable, on this Note, without set off or counterclaim,

at the time, place, and rate, and in the coin or currency, herein prescribed. This Note is a direct debt obligation of the Company. This

Note ranks pari passu with all other Purchase Agreement Notes now or hereafter issued under the terms set forth in the Transaction

Documents and is at least pari passu with all Indebtedness and other obligations of the Company, and is not subordinated to any

such Indebtedness or other obligation.

c) Lost or Mutilated Note.

If this Note shall be mutilated, lost, stolen or destroyed, the Company shall execute and deliver, in exchange and substitution for and

upon cancellation of a mutilated Note, or in lieu of or in substitution for a lost, stolen or destroyed Note, a new Note for the principal

Note, and of the ownership hereof, reasonably satisfactory to the Company.

d) Dispute Resolution.

dispute relating to the determination of any of the foregoing), the Company or the Holder (as the case may be) shall submit the dispute

to the other party via facsimile or electronic transmission (A) if by the Company, within two (2) Trading Days after the occurrence of

the circumstances giving rise to such dispute or (B) if by the Holder at any time after the Holder learned of the circumstances giving

rise to such dispute. If the Holder and the Company are unable to promptly resolve such dispute, at any time after the second (2nd)

Trading Day following such initial notice, then the Holder may, at its sole option, select an independent, reputable investment bank to

resolve such dispute.

- 27 -

ii. The Holder and the

Company shall each deliver to such investment bank (A) a copy of the initial dispute submission so delivered in accordance with clause

supporting its position with respect to such dispute, in each case, no later than 5:00 p.m. (New York time) by the fifth (5th)

Trading Day immediately following the date on which the Holder selected such investment bank (the “Dispute Submission Deadline”)

. If either party fails to so deliver all of the Required Dispute Documentation by the Dispute Submission Deadline, then such party shall

no longer be entitled to (and hereby waives its right to) deliver or submit any document or other supporting evidence to such investment

bank with respect to such dispute and such investment bank shall resolve such dispute based solely on the Required Dispute Documentation

that was delivered to such investment bank prior to the Dispute Submission Deadline. Unless otherwise agreed to in writing by both the

Company and the Holder or otherwise requested by such investment bank, neither the Company nor the Holder shall be entitled to deliver

or submit any written documentation or other support to such investment bank in connection with such dispute other than the Required Dispute

Documentation.

iii. The Company and

the Holder shall ensure that such investment bank determines the resolution of such dispute and notify the Company and the Holder of such

resolution no later than ten (10) Trading Days immediately following the Dispute Submission Deadline. The fees and expenses of such investment

bank shall be borne solely by the Company, and such investment bank’s resolution of such dispute shall be final and binding upon

all parties absent manifest error.

e) Governing Law; Courts.

than as set forth in clause (d) above) and matters related hereto or arising hereunder or arising from or relating to the relationship

among any of the parties hereto, are governed by, and shall be construed, interpreted and enforced exclusively in accordance with, the

laws of the State of Delaware (without giving effect to the conflict of laws provisions thereof to the extent such principles or rules

would require or permit the application of the laws of any jurisdiction other than those of the State of Delaware). Any such Proceeding

shall be brought exclusively in the Delaware state courts sitting in Wilmington, DE or the federal courts of the United States of America

for the District of Delaware sitting in Wilmington, DE; provided, that the Collateral Agent, the Holder and the other Purchaser Parties

may bring Proceedings in other jurisdictions to enforce this Note. The parties hereto have accepted such jurisdiction and waived venue

and other objections and have agreed to the means for service of process in such Section 6.6.

f) Characterizations. The

Company covenants to the Holder that there shall be no characterization concerning this instrument other than as expressly provided herein.

Amounts set forth or provided for herein with respect to payments, conversion and the like (and the computation thereof) shall be the

amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company

(or the performance thereof).

g) Payments on Next Business

Day. Whenever any payment Obligation shall be due on a day other than a Business Day, such payment shall be due instead on the next

succeeding Business Day.

h) Payment of Collection, Enforcement

and Other Costs. In addition to, and not in substitution for and not to limit (but without duplication), any other right to reimbursement

under this Note or any other Transaction Document, (i) this Note is placed in the hands of an attorney for collection or enforcement or

is collected or enforced through any Proceeding or the Holder otherwise takes action to collect amounts due under this Note or to enforce

the provisions of this Note or (ii) there occurs any bankruptcy, reorganization, receivership of the Company or other Proceedings affecting

Company creditors’ rights and involving a claim under this Note, then the Company shall pay all out-of-pocket costs incurred by

- 28 -

j) Use of Proceeds. All

proceeds of the purchase of this Note and the other Purchased Securities shall be used as provided in the Purchase Agreement.

k) Non-Public Information.

Except with respect to the Transaction Documents and the transactions contemplated thereunder, which shall be disclosed as provided in

the Purchase Agreement, each Company Party covenants and agrees that neither it, nor any other Person acting on its behalf has

provided nor will provide the Holder or its agents or counsel with any information that constitutes, or the Company reasonably believes

constitutes, material non-public information, unless prior thereto the Holder shall have consented to the receipt of such information

and agreed with the Company to keep such information confidential. Any non-disclosure agreement entered into with the Holder and any Company

Party are terminated as provided in Section 4.9 (Securities Laws Disclosures) of the Purchase Agreement. The Holder does not have

any duty of confidentiality (or a duty not to trade on the basis of material non-public information) to any Company Party or any of their

Affiliates, or any of their respective officers, directors, agents, members, stockholders, managers, employees and is governed only by

application Regulations. Each Company Party understands and confirms that the Holder shall be relying on all of the foregoing covenants

in trading Securities of the Company.

l) Public Disclosures.

The Company Parties and the Holder shall consult with each other in issuing any other public disclosure with respect to the transactions

contemplated hereby, and no Company Party or the Holder shall issue any such public disclosure nor otherwise make any such public statement

without the prior consent of the Company and the Holder, each of which consent shall not unreasonably be withheld or delayed, except if

such disclosure is reasonably viewed as required by any Regulation, in which case the disclosing party shall promptly provide the other

party with prior notice of such public statement or communication. Notwithstanding the foregoing, no Company Party shall, and each Company

Party shall ensure that their Subsidiaries do not, publicly disclose the name, trademark, service mark, symbol, logo (or any abbreviation,

contraction or simulation thereof) of, or otherwise refer to, the Holder or any other Purchaser Party (including in any filing with the

SEC, regulatory agency or Trading Market for any Securities of any Company Party or their Subsidiaries, including the 8-K filing referenced

above) without the prior consent of the Holder and the Collateral Agent (including in any press release, letterhead, public announcement

or marketing material), except, and then only after consulting with such Holder and the Collateral Agent, to the extent required to do

so under applicable Regulations (including as required in any registration statement filed with the SEC). None of the Company Parties

and their Affiliates shall represent that any Company Party or any of its Affiliates, any product or service of the Company Parties or

their Affiliates, or any know how or policy or practice of the Company Parties or their Affiliates has been approved or endorsed by any

Purchaser Party.

m) Interpretation. This

Note is a Transaction Document and as such is subject to various interpretative, amendment and third party beneficiary and other miscellaneous

provisions set forth in the Purchase Agreement that expressly apply to Transaction Documents, located principally in Article VI (Miscellaneous)

thereof (including Section 4.9 (Securities Law Disclosures) which, among other things, restrict public disclosures of the name

of the Holder, Section 6.15 (Interpretation) that provides, among other things, that payments due on a day that is not a Business

Day may be made on the next Business Day), as well as, without limitation, set off provisions in Section 6.5 (Set Off) thereof

whereby amounts owing hereunder may be set off against amounts owed by the Holder and certain related entities, indemnification and expense

reimbursement provisions in Sections 4.14 (Indemnification of Each Purchaser Party) and 6.2 (Fees and Expenses) thereof

that benefit the Holder, among others. In particular, without limitation, (i) none of the terms or provisions of this Note may be waived,

amended, supplemented or otherwise modified except in accordance with Section 6.3(b) (Amendments) of the Purchase Agreement and

(ii) as described in Section 6.3(a) (Entire Agreement) of the Purchase Agreement, this Note and the other Transaction Documents

contain and constitute the entire agreement of the parties with respect to the subject matter hereof. Any Holder also benefits from various

provisions of the Purchase Agreement applicable to “Purchasers” (whether by virtue of being an “Initial Purchaser”

or successor in interest thereto) and agrees to be bound by the provisions of the Purchase Agreement applicable to it in such capacity,

including Article V (Collateral Agent) thereof that describes its relationship with the Collateral Agent and contains an indemnification

provision in Section 5.9 (Indemnification) thereof. Finally, in addition to these provisions, unless otherwise expressly provided

in any Transaction Document, “outstanding” when referring in any Transaction Document to the principal amount owing

under this Note shall mean “outstanding and unconverted.”

- 29 -

n) Beneficiaries; Successors

and Assigns. As provided in Section 6.3(c) (Beneficiaries; Successors and Assigns) of the Purchase Agreement, this Note shall

Collateral Agent, each of their Purchaser Parties and their respective successors and, if permitted, assigns; provided, that no

Company Party may assign any part of this Note, or any right, obligation, benefit, title or interest hereunder except as authorized in

the Purchase Agreement.

executed in any number of counterparts, which may be signed and transmitted electronically.

p) Severability. As provided

in Section 6.7 (Severability) of the Purchase Agreement, any provision of this Note being held illegal, invalid or unenforceable

in any jurisdiction shall not affect any part of such provision not held illegal, invalid or unenforceable, any other provision of this

Note or any part of such provision in any other jurisdiction, so long as the economic or legal substance of the transaction contemplated

hereby is not affected in any manner adverse to any party.

q) Waiver of Jury Trial. As

other Obligations (as defined below). In addition, the Company shall pay in full on the Maturity Date all remaining Obligations then outstanding.

b) Mandatory Prepayments. On the next Business

Day following the Company consummating any public or private offering or any other issuance of any Capital Stock or any other issuance

of any Capital Stock (other than any issuance of Common Stock to the general public), Stock Equivalents or of any other Securities or

Indebtedness (including entering into any Equity Line of Credit or issuing any Variable-Priced Equity-Linked Instrument) or any other

statement on Form S-1 filed after the date hereof). The Holder may continue to convert the principal amounts to be prepaid under this

Note until the date of consummation of such Subsequent Offering. This Section 2(b) is merely a requirement to redeem this Note and not

an authorization to consummate any Subsequent Offering otherwise prohibited by the Transaction Documents.

- 42 -

c) Voluntary Prepayments. So long as no

Default or Event of Default exists, at any time upon ten (10) Business Days’ prior written notice to the Holder (which notice shall

be a Transaction Document and constitute an irrevocable agreement to pay such amount on the date set forth on such notice) stating the

proposed date and proposed principal amount of such prepayment, but subject to the Holder’s conversion rights set forth herein,

the Company may prepay any portion of the principal amount of this Note, any accrued and unpaid interest, and any other amounts due under

this Note. If the Company exercises its right to prepay the Note, instead of such principal amount, the Company shall pay to the Holder

in cash an amount equal to the full Optional Prepayment Amount for such principal amount prepaid. The Holder may continue to convert the

principal amount of the Note to be prepared after the date notice of the prepayment is given until the date it receives such Optional

Prepayment Amount in full in cash.

d) Interest. The Company shall pay interest

to the Holder on the aggregate then-outstanding principal amount of this Note (and the then-outstanding principal amount of any other

Obligation owing that does not expressly provide for any other rate of interest), which shall accrue daily at the rate of twelve percent

(12%) per annum from the date this Note is issued (or in the case of any other Obligation, from the date such obligation becomes due and

payable) through the date such principal amount or other Obligation is paid in full; provided, that the Minimum Interest Amount

shall be fully earned and accrued on the Original Issue Date. Accrued interest shall replace and not add to the Minimum Interest Amount

and all payments of such accrued interest shall cause a corresponding reduction in any remaining Minimum Interest Amount. Accrued and

unpaid interest shall be due and payable in cash on the first day of each calendar month and on the Maturity Date, or as otherwise set

forth herein. Any interest accrued and unpaid on any principal amount, and any remaining Minimum Interest Amount on such principal amount,

shall be due and payable upon any repayment of such principal amount under this Note. Upon an Event of Default, the interest rate set

forth hereunder shall increase as provided in clause (e) below. The Minimum Interest Amount is intended to compensate the Holder

for a lesser profit in case of early repayment and for the internal and external work and expenditure of time and money involved in the

evaluation and preparation of the Transaction Documents and the consummation of the transactions contemplated thereunder. The Minimum

Interest Amount is not to be construed to cover or be applied against any indemnity or any out-of-pocket fees, costs or expenses incurred

in any action to collect any Obligation or to foreclose any Lien securing the same. This provision shall not affect or limit the Holder’s

rights or remedies with respect to any Event of Default.

e) Default Rate. Immediately on and after

the occurrence of any Event of Default, without need for notice or demand all of which are waived, interest on this Note shall, in whole,

automatically and without the need for any notice, demand or any other action by the Collateral Agent or the Holder all of which are hereby

waived, accrue and be owed daily at an increased interest rate equal to the lower of the Default Rate or the maximum rate permitted under

applicable Regulations. If an Event of Default (after giving effect to notice periods and grace periods) occurs, the Default Rate shall

become effective as of the date the Default that because such Event of Default first occurred, without consideration for any notice provision

or grace period.

f) Late Fee. The Company shall pay a late

fee (each a “Late Fee”) on any Obligation that is not paid when due (after taking into account applicable grace periods

set forth in Section 7(a)(i) hereof), in an amount equal to ten percent (10%) of such payment, to the Person owed such Obligation. This

Late Fee shall be due and payable immediately upon such failure. It is intended to cover the inconvenience and additional internal, administrative

and other fees, costs and expenses involved in processing delinquent payments and is not to be construed to cover or be applied against

any indemnity or any out-of-pocket fees, costs or expenses incurred in any action to collect any Obligation or to foreclose any Lien securing

the same. This provision shall not affect or limit the Holder’s rights or remedies with respect to any Event of Default. This obligation

to pay a Late Fee is a separate obligation and, once it has arisen hereunder, a failure to pay such Late Fee will not be cured implicitly

by any waiver of any Event of Default or similar event that may have caused the payment that gave rise to such Late Fee.

g) Cash Payment Fee. The Company shall pay

a cash payment fee (each a “Cash Payment Fee”) in an amount equal to five percent (5%) of the amount of any repayment

of the principal amount of this Note that is made in cash at any time when (i) the Company shall not have received a notice from the Holder

or the Collateral Agent that an Event of Default exists, or (ii) the Company shall have received such a notice and such Event of Default

shall have been cured to the satisfaction of the Holder. This Cash Payment Fee shall be due and payable together with such repayment and

is intended to cover any loss in revenues resulting from such repayment being made in cash instead of using Common Stock, as well as other

internal costs and expenses and is not to be construed to cover or be applied against any indemnity or any out-of-pocket fees, costs or

expenses incurred in any action to collect any Obligation or to foreclose any Lien securing the same. The Cash Payment Fee shall not be

applicable to the payment of any Mandatory Prepayment Amount. This provision shall not affect or limit the Holder’s rights or remedies

with respect to any Event of Default. This obligation to pay a Cash Payment Fee is a separate obligation hereunder and, once arisen, shall

be owed regardless of whether such payment is later returned, reversed, forgiven, waived or voided.

- 43 -

h) Calculations and Payment Provisions.

All payments made to the Holder, the Collateral Agent and their Purchaser Parties under any Transaction Document, except as otherwise

expressly provided in any Transaction Document, shall be made in cash, which shall mean in immediately available dollars and without set

off or counterclaim. Interest and fees owing to any of them shall be calculated on the basis of a 360-day year consisting of twelve thirty

(30)-day periods, for the actual number of days occurring, in whole or in part, in the applicable period. The Holder (or, for payments

owing to it, the Collateral Agent) shall have the option to refuse or accept, in their sole discretion, any payment to the Collateral

Agent, the Holder or their Purchaser Parties attempted to be made without a required notice, without a required Optional Prepayment Amount,

a Minimum Interest Amount or a required fee. The Holder (or, for payments owing to the Collateral Agent, the Collateral Agent) may, in

its sole discretion, apply or recharacterize any payment made under any Transaction Document to the payment of any outstanding Obligation,

regardless of the intended characterization thereof by any Company Party, including by recharacterizing a payment of principal made to

a payment of an Optional Prepayment Amount, a Minimum Interest Amount or a required fee, even if this characterization results in a smaller

payment of principal. The Company hereby irrevocably waives the right to direct the application of any payment (or, after any Event of

Default, any proceeds of Collateral) to any Obligation. Whenever any payment under any Transaction Document shall be stated to be due

on a day other than a Business Day, such payment shall be due on the next succeeding Business Day, including for purposes of the calculation

of interest and fees. Any payment of any Obligation received by the Holder, the Collateral Agent or any Purchaser Party after 3 p.m. on

any day shall be deemed received on the next Business Day. Each determination by the Holder (or, for payments owing to it, the Collateral

Agent) of an amount of interest or fee due hereunder shall be conclusive and binding for all purposes, absent manifest error.

Section

3. Registration of Transfers and Exchanges

a) Different Denominations. This Note is

exchangeable for an equal aggregate principal amount of Notes of different authorized denominations, as requested by the Holder surrendering

the same. No service charge will be payable for such registration of transfer or exchange.

b) Investment Representations. This Note

has been issued subject to certain investment representations of the original Holder and may be transferred or exchanged only in compliance

with applicable federal and state securities Regulations.

c) Reliance on Note Register. The Company

shall maintain in its records a list of the Holders and of registration and transfers of the Note (the “Note Register”).

The initial Holder is listed herein. Any Holder may later notify in writing the Company of an assignment or transfer and the Company shall

notify such transfer in the Note Register. Failure by the Company to duly notify such transfer in the Note Register shall not affect the

validity of such assignment or transfer. Nevertheless, if the Company has not received notice of any transfer of this Note, the Company

and any agent of the Company may treat the Person in whose name this Note is duly registered as the owner hereof for the purpose of receiving

payment as herein provided and for all other purposes, whether or not this Note is overdue. Upon request by the Holder, the Company shall

immediately execute and deliver to such Holder replacement Note or Notes, which may involve executing multiple Notes with split amounts

to reflect partial assignments. Promptly upon receipt of such replacement Note or Notes, such Holder shall deliver the original Note back

to the Company or, if the original Note is lost or stolen, provide an affidavit to the Company to that effect.

- 44 -

Section

4. Conversion

a) Voluntary Conversion. At any time after

the Original Issue Date, all Obligations with respect to this Note shall be convertible, in whole or in part, into shares of Common Stock

at the option of the Holder, in its sole discretion, at any time and from time to time (subject to the conversion limitations set forth

in Section 4(d)). The Holder shall effect conversions by delivering to the Company a Notice of Conversion, the form of which is

attached hereto as Annex A (each, a “Notice of Conversion”), specifying therein the amount of such Obligations

to be converted and the date on which such conversion shall be effected (such date, the “Conversion Date”). If no Conversion

Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion is deemed delivered

hereunder. No ink-original Notice of Conversion shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization)

of any Notice of Conversion form be required. To effect conversions hereunder, the Holder shall not be required to physically surrender

this Note to the Company unless the entire principal amount of this Note, plus all accrued and unpaid interest thereon, has been converted.

Conversions hereunder shall have the effect of lowering the outstanding principal amount of this Note by an amount equal to the applicable

conversion. The Holder and the Company shall maintain a Conversion Schedule, containing at a minimum the information shown on Schedule

1, and showing historically, among other things, the principal amounts converted and the date of such conversions. The Company may

deliver an objection to any Notice of Conversion within one (1) Business Day of delivery of such Notice of Conversion. In the event of

any dispute or discrepancy, the records of the Holder shall be controlling and determinative in the absence of manifest error.

b) Conversion Price. Subject to the other

provisions of this Note, the conversion price in effect on any Conversion Date (the “Conversion Price”) shall be equal

to $0.50, subject to adjustment as provided herein; provided, that in no event shall the Conversion Price be less than the Floor Price.

c) Mechanics of Conversion.

i. Conversion Shares Issuable Upon

Conversion of Principal Amount. The number of Conversion Shares issuable upon a conversion hereunder shall be determined by the quotient

obtained by dividing (x) the outstanding principal amount and interest of this Note to be converted by (y) the Conversion Price.

ii. Delivery of Certificate Upon Conversion.

Not later than one (1) Trading Day after each Conversion Date (the “Share Delivery Date”), the Company shall deliver,

or cause to be delivered, to the Holder a certificate or certificates representing the Conversion Shares which, on or after the date on

which such Conversion Shares are eligible to be sold under Rule 144 without the need for current public information and the Company has

received an opinion of counsel to such effect, which such opinion must be acceptable to the Holder in its sole and absolute discretion

(which opinion the Company shall be responsible for obtaining at its sole cost and expense) shall be free of restrictive legends and trading

restrictions, representing the number of Conversion Shares being acquired upon the conversion of this Note. Each certificate required

to be delivered by the Company under this Section 4(c) shall be delivered electronically through the Depository Trust Company or

another established clearing corporation performing similar functions. If the Conversion Date is prior to the date on which such Conversion

Shares are eligible to be sold under Rule 144 without the need for current public information, or there is no registration statement in

effect covering the Conversion Shares, the Conversion Shares shall bear a restrictive legend in the following form, as appropriate:

“THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED

BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES REGULATIONS.

THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT

FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL (WHICH COUNSEL SHALL BE SELECTED BY THE

HOLDER), IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144 OR

RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR

OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.”

Notwithstanding the foregoing, commencing on such date that

the Conversion Shares are eligible for sale under Rule 144 subject to current public information requirements, the Company, upon written

request and at the sole cost and expense of the Company, shall obtain a legal opinion that is acceptable to the Holder in its sole and

absolute discretion, to allow for such sales under Rule 144.

- 45 -

iii. Reservation of Conversion Shares.

The Company covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock a

number of shares of Common Stock at least equal the Reserve Amount for the sole purpose of issuance upon conversion of this Note and payment

of interest on this Note, each as herein provided, free from preemptive rights or any other actual contingent purchase rights of Persons

other than the Holder (and the other holders of the Purchase Agreement Notes). The Company covenants that all shares of Common Stock that

shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and nonassessable. The Company shall calculate

and readjust the Reserve Amount on the first Business Day of each month so long as any Purchased Security remains outstanding.

iv. Fractional Shares. No fractional

shares or scrip representing fractional shares shall be issued upon the conversion of this Note. As to any fraction of a share which the

Holder would otherwise be entitled to purchase upon such conversion, the Company shall at its election, either pay a cash adjustment in

respect of such final fraction in an amount equal to such fraction multiplied by the Conversion Price or round up to the next whole share.

v. Transfer Taxes and Expenses.

The issuance of certificates for shares of the Common Stock on conversion of this Note shall be made without charge to the Holder hereof

for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificates, provided,

that, the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery

of any such certificate upon conversion in a name other than that of the Holder of this Note so converted and the Company shall not be

required to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to

the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. The Company

shall pay all Transfer Agent fees required for same-day processing of any Notice of Conversion

vi. Failure to Deliver Certificates.

If, in the case of any Notice of Conversion, such certificate or certificates are not delivered to or as directed by the applicable Holder

by the Share Delivery Date, the Holder shall be entitled to elect by written notice to the Company at any time on or before its receipt

of such certificate or certificates, to rescind such Conversion, in which event the Company shall promptly return to the Holder any original

Note delivered to the Company and the Holder shall promptly return to the Company the Common Stock certificates issued to the Holder pursuant

to the rescinded Notice of Conversion.

vii. Obligation Absolute; Partial

Liquidated Damages. The Company’s obligations to issue and deliver the Conversion Shares upon conversion of this Note in accordance

with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, the existence

of any Default or Event of Default, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any

Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged

breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of Regulations by the

Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the

Holder in connection with the issuance of such Conversion Shares; provided, that such delivery shall not operate as a waiver by

the Company of any such action the Company may have against the Holder. In the event the Holder of this Note shall elect to convert any

or all of the outstanding principal or interest amount hereof, the Company may not refuse conversion based on any claim that the Holder

or anyone associated or affiliated with the Holder has been engaged in any violation of Regulation, Contractual Obligation or for any

other reason, unless an injunction from a court, on notice to Holder, restraining and or enjoining conversion of all or part of this Note

shall have been sought. If the injunction is not granted, the Company shall promptly comply with all conversion obligations herein. If

the injunction is obtained, the Company must post a surety bond for the benefit of the Holder in the amount of one hundred fifty percent

(150%) of the outstanding principal amount of this Note, which is subject to the injunction, which bond shall remain in effect until the

completion of arbitration/litigation of the underlying dispute and the proceeds of which shall be payable to the Holder to the extent

it obtains judgment. In the absence of seeking such injunction, the Company shall issue Conversion Shares (or, where applicable and required

hereunder, cash), upon a properly noticed conversion. If the Company fails for any reason to deliver to the Holder such certificate or

certificates pursuant to Section 4(c)(ii) by the Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated

damages and not as a penalty, $1,000 per Trading Day for each Trading Day after such Share Delivery Date until such certificates are delivered

or Holder rescinds such conversion. Nothing herein shall limit a Holder’s right to pursue actual damages or declare an Event of

Default pursuant to Section 7 for the Company’s failure to deliver Conversion Shares within the period specified herein and

the Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including a decree of specific performance

and/or injunctive relief. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant to any

other Section hereof or under applicable Regulation.

- 46 -

viii. Compensation for Buy-In on Failure

to Timely Deliver Certificates Upon Conversion. In addition to any other rights available to the Holder, if the Company fails for

any reason to deliver to the Holder such certificate or certificates by the Share Delivery Date pursuant to Section 4(c)(ii), and

if after such Share Delivery Date the Holder is required by its brokerage firm to purchase (in an open market transaction or otherwise),

or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of

the Conversion Shares which the Holder was entitled to receive upon the conversion relating to such Share Delivery Date (a “Buy-In”),

then the Company shall (A) pay in cash to the Holder (in addition to any other remedies available to or elected by the Holder) the amount,

if any, by which (x) the Holder’s total purchase price (including any brokerage commissions) for the Common Stock so purchased exceeds

(y) the product of (1) the aggregate number of shares of Common Stock that the Holder was entitled to receive from the conversion at issue

multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage

commissions) and (B) at the option of the Holder, in its sole discretion, either reissue (if surrendered) this Note in a principal amount

equal to the principal amount of the attempted conversion (in which case such conversion shall be deemed rescinded) or deliver to the

Holder the number of shares of Common Stock that would have been issued if the Company had timely complied with its delivery requirements

under Section 4(c)(ii). For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In

with respect to an attempted conversion of this Note with respect to which the actual sale price of the Conversion Shares (including any

brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence,

the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable

to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit

the Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including a decree of specific performance

and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock

upon conversion of this Note as required pursuant to the terms hereof.

ix. No Limitation on Damages. More

generally, nothing in this Section 4, including the availability of the option to convert the Note, shall limit the Holder’s

right to pursue actual damages or declare an Event of Default pursuant to Section 7 and the Holder shall have the right to pursue

all remedies available to it hereunder, at law or in equity including a decree of specific performance and/or injunctive relief. The exercise

of any rights under this Section 4 shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section

hereof or under applicable Regulation.

- 47 -

d) Holder’s Conversion Limitations.

The Company shall not effect any conversion of principal or interest of this Note, and the Holder shall not have the right to convert

any principal or interest of this Note, to the extent that after giving effect to the conversion set forth on the applicable Notice of

Conversion, the Holder (together with the Holder’s Affiliates, and any Persons acting as a group together with the Holder or any

of the Holder’s Affiliates, the “Attribution Parties”) would beneficially own in excess of the Beneficial Ownership

Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the

Holder and its Attribution Parties shall include the number of Conversion Shares issuable upon conversion of this Note with respect to

which such determination is being made, but shall exclude the number of shares of Common Stock issuable upon (i) conversion of the remaining,

unconverted principal amount of this Note beneficially owned by the Holder or any of its Attribution Parties and (ii) exercise or conversion

of the unexercised or unconverted portion of any other Securities of the Company subject to a limitation on conversion or exercise analogous

to the limitation contained herein (including any other Notes) beneficially owned by the Holder or any of its Attribution Parties. Except

as set forth in the preceding sentence, for purposes of this Section 4(d), beneficial ownership shall be calculated in accordance

with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation contained

in this Section 4(d) applies, the determination of whether this Note is convertible (in relation to other Securities owned by the

Holder together with any Attribution Parties) and of which principal amount of this Note is convertible shall be in the sole discretion

of the Holder, and the submission of a Notice of Conversion shall be deemed to be the Holder’s determination of whether this Note

may be converted (in relation to other Securities owned by the Holder together with any Attribution Parties) and which principal amount

of this Note is convertible, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction,

the Holder will be deemed to represent to the Company each time it delivers a Notice of Conversion that such Notice of Conversion has

not violated the restrictions set forth in this paragraph and the Company shall have no obligation to verify or confirm the accuracy of

such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section

13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 4(d), in determining

the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as stated in

the most recent of the following: (i) the Company’s most recent periodic or annual report filed with the SEC, as the case may be,

(ii) a more recent public announcement by the Company, or (iii) a more recent written notice by the Company or the Company’s transfer

agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of the Holder, the Company shall

within two (2) Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any

case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of Securities

of the Company, including this Note, by the Holder or its Attribution Parties since the date as of which such number of outstanding shares

of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common

Stock outstanding immediately after giving effect to the issuance of all Conversion Shares to be held by the Holder. The Holder, upon

not less than sixty-one (61) days’ prior notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions

of this Section 4(d); provided, that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares

of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon conversion of this Note

held by the Holder. Any such increase or decrease will not be effective until the sixty-first (61st) day after such notice

is delivered to the Company. The Beneficial Ownership Limitation provisions of this paragraph shall be construed and implemented in a

manner otherwise than in strict conformity with the terms of this Section 4(d) to correct this paragraph (or any portion hereof)

which may be defective or inconsistent with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements

necessary or desirable to properly give effect to such limitation. The limitations contained in this Section 4(d) shall apply to

a successor Holder of this Note.

e) Exchange Cap. The Company shall not issue

any shares of Common Stock upon conversion of this Note or otherwise pursuant to the terms of this Note if the issuance of such shares

of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue upon conversion of this Note or

otherwise pursuant to the terms of this Note without breaching the Company’s obligations under the rules or regulations of the Principal

Trading Market for the Common Stock (the number of shares which may be issued without violating such rules and regulations, the “Exchange

Cap”), except that such limitation shall not apply in the event that the Company (i) obtains the approval of its stockholders

as required by the applicable rules of such Principal Trading Market for issuances of shares of Common Stock in excess of such amount

or (ii) obtains a written opinion from outside counsel to the Company that such approval is not required, which opinion shall be in form

and substance reasonably satisfactory to the Holder. Until such approval or such written opinion is obtained, the Holder shall not be

issued in the aggregate, upon conversion of this Note or otherwise pursuant to the terms of this Note, shares of Common Stock in an amount

greater than the product of (A) the Exchange Cap as of the proposed date of issuance for such shares multiplied by (B) the quotient of

(1) the aggregate original Principal Amount of this Note when issued to the applicable Purchaser pursuant to the Purchase Agreement divided

by (2) the aggregate original Principal Amount of all Purchase Agreement Notes when issued (the “Exchange Cap Allocation”).

In the event that the Holder sells or otherwise transfer any portion of this Note, the transferee shall be allocated a pro rata portion

of the Holder’s Exchange Cap Allocation with respect to such portion of this Note so transferred, and the restrictions of the prior

sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation so allocated to such transferee. Upon

conversion in full of any holder of any Purchase Agreement Note, the difference (if any) between such holder’s “exchange cap

allocation” (under and as defined in such Purchase Agreement Note) and the number of shares of Common Stock actually issued to such

holder upon such holder’s conversion in full of any Purchase Agreement Note shall be allocated to the respective Exchange Cap Allocations

of the remaining holders of such Purchase Agreement Notes (including the Holder) on a pro rata basis in proportion to the shares of Common

Stock underlying such Purchase Agreement Notes then held by each such holder. In the event that the Company is prohibited from issuing

any shares of Common Stock pursuant to this Section 4(e)(the “Exchange Cap Shares”) to the Holder, the Company

shall pay cash to the Holder in exchange for the redemption of such portions of this Note that are not convertible into such Exchange

Cap Shares at a price equal to the sum of (A) the product of (1) such number of Exchange Cap Shares and (2) the Closing Sale Price on

the Trading Day immediately preceding the date the Holder delivers the applicable Notice of Conversion with respect to such Exchange Cap

Shares to the Company, and (B) to the extent the Holder purchases (in an open market transaction or otherwise) shares of Common Stock

to deliver in satisfaction of a sale by the Holder of Exchange Cap Shares, brokerage commissions, if any, of the Holder incurred in connection

therewith.

Section

5. Certain Adjustments

a) Stock Dividends and Stock Splits. If

the Company, at any time while this Note is outstanding: (i) pays a stock dividend or otherwise makes a Restricted Payment payable in

shares of Common Stock on shares of Common Stock or any Stock Equivalents (which, for avoidance of doubt, shall not include any shares

of Common Stock issued by the Company upon conversion of, or payment of interest on, this Note), (ii) subdivides outstanding shares of

Common Stock into a larger number of shares, (iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock

into a smaller number of shares or (iv) issues, in the event of a reclassification of shares of the Common Stock, any shares of capital

stock of the Company, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares

of Common Stock (excluding any treasury shares of the Company) outstanding immediately before such event, and of which the denominator

shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section

5(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend

or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

b) Change in Option Price or Rate of Conversion.

If the purchase or exercise price provided for in any options to purchase Common Stock, the additional consideration, if any, payable

upon the issue, conversion, exercise or exchange of any Stock Equivalents into Common Stock, or the rate at which any Stock Equivalents

are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time (other than any change

to the Conversion Price in this Note or any changes to the exercise price in the Warrants), the Conversion Price in effect at the time

of such increase or decrease shall be adjusted to account proportionately, for such increase or decrease. For purposes of this Section

5(b), if the terms of any option or Stock Equivalents are increased or decreased in the manner described in the immediately preceding

sentence, then such option or Stock Equivalents and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof

shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section 5(b) shall

be made to the Conversion Price if such adjustment would result in an increase to the Conversion Price.

c) Subsequent Equity Sales. If any Company

Party or any Subsidiary thereof, at any time while any Obligation is outstanding or the Holder has not yet received any Conversion Shares

in connection with a conversion, shall sell or grant any option to purchase, or sell or grant any right to reprice, or otherwise dispose

of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any shares of Common Stock or Stock Equivalents

convertible or exchangeable into Common Stock, in each case other than as an Exempt Issuance, at an effective price per share that, after

giving effect to any other adjustment provided in this Note, is less than the Conversion Price then in effect (such lower price, the “Base

Share Price” and such issuances collectively, a “Dilutive Issuance”) then, simultaneously with the consummation

of each Dilutive Issuance the Conversion Price shall be reduced and only reduced to equal the Base Share Price. For the avoidance of doubt,

it is understood and agreed that if a holder of the shares of Common Stock or Stock Equivalents so issued shall, at any time after the

issuance, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise,

or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive shares of Common

Stock at an effective price per share that is less than the Conversion Price, such issuance shall be deemed to have occurred for less

than the Conversion Price on such date of the Dilutive Issuance at such effective price. Such adjustment shall be made whenever such shares

of Common Stock or Stock Equivalents are issued. No later than 8:00 am on the Trading Day following the issuance or deemed issuance of

any shares of Common Stock or Stock Equivalents subject to this Section 5(c), the Company shall (i) notify the Holder, in writing,

indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price and other pricing terms

(such notice, the “Dilutive Issuance Notice”) and (ii) publicly disclose the transaction resulting in such issuance

or deemed issuance in a filing with the SEC. For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice

pursuant to this Section 5(c), upon the occurrence of any Dilutive Issuance, the Holder is entitled to receive a number of Conversion

Shares based upon the Base Share Price regardless of whether the Holder accurately refers to the Base Share Price in the Notice of Conversion.

- 49 -

d) Pro Rata Distributions. While this Note

is outstanding, the Company shall not declare or make any Restricted Payment (or rights to receive Restricted Payments). In the event

that the Note is repaid at the time of such Restricted Payment, the Holder shall not be entitled to participate in such Restricted Payment.

If the Holder and the Company mutually agree, and the Note is not repaid at the time of such Restricted Payment, then the Holder shall

be entitled to participate in such Restricted Payment to the same extent that the Holder would have participated therein if the Holder

had held the number of shares of Common Stock acquirable upon complete exercise of this Note (without regard to any limitations on exercise

hereof, including the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Restricted Payment,

or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation

in such Restricted Payment (provided, that to the extent that the Holder’s right to participate in any such Restricted Payment

would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such

Restricted Payment to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Restricted Payment

to such extent) and the portion of such Restricted Payment shall be held in abeyance for the benefit of the Holder until such time, if

ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

e) Effect of Fundamental Transactions. Upon

the occurrence of any Fundamental Transaction, the Holder, upon any subsequent conversion of this Note, shall have the right to receive,

for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction

(without regard to any limitation in Section 4(c) on the conversion of this Note), any consideration receivable as a result of

such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Note is convertible (or holder of any

equity Securities of any Company Party) immediately prior to such Fundamental Transaction (without regard to any limitation in Section

4(c) on the conversion of this Note) (the “Alternate Consideration”), including shares of Common Stock of any successor

or acquiring corporation or of the Company, in the case of a merger where it is the surviving entity. To the extent such Alternate Consideration

includes Securities, the Holder shall have the option to either treat the Note as converted on the date of consummation of such Fundamental

Transaction and obtain such Securities outright or adjust the Conversion Shares to include such additional Securities. For purposes of

any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration

based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the

Company Parties shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative

value of any different components of the Alternate Consideration. In a Fundamental Transaction where holders of Common Stock (or, as the

case may be, Securities of any Company Party) are given any choice as to the Alternate Consideration to be received in a Fundamental Transaction,

then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Note following

such Fundamental Transaction. The Company shall cause any acquiring, successor, surviving or replacement entities in any Fundamental Transaction

(the “Successor Entity”) to become a Company Party effective immediately upon the consummation of such Fundamental

Transaction and shall become a party to all Transaction Documents in the same capacity and to the same extent as the Company Party involved

in such Fundamental Transaction and, if such Fundamental Transaction involves the Company, from and after the date of such Fundamental

Transaction, the provisions of this Note and the other Transaction Documents referring to the “Company” shall, without any

further action, refer instead to the Successor Entity or to both Companies, as appropriate. In the case of a Fundamental Transaction resulting

in the Company no longer be in existence, the Successor Entity shall succeed to all obligations of the Company and may exercise every

right and power of the Company and shall assume all of the Obligations of the Company with the same effect as if such Successor Entity

had been named as the Company herein. The parties hereto shall amend all Transaction Documents (or execute new Transaction Documents,

including replacement Notes and an assumption of the Company’s Obligations) to reflect such change; provided that the failure

to amend or execute any such Transaction Document shall not render this clause (e) ineffective. For the avoidance of doubt, this

clause (e) is not intended to permit any Fundamental Transaction. The Company shall ensure that the Holder approves all drafts

of such amendments and new Transaction Documents prior to the consummation of, and as a condition to the consummation of, such Fundamental

Transaction. Without limitation, if the Fundamental Transaction involves the Company, the definition of Conversion Shares and Conversion

Price hereunder shall be adjusted to include Securities of the Successor Entity and to ensure the new Notes of the Holder convert into

Securities so as to protect the economic value of this Note, taking into account the relative values of the existing and replacement Conversion

Shares, and give the Holder upon conversion of this Note the Conversion Shares equivalent to the Conversion Shares it would have received

upon conversion of this Note prior to such Fundamental Transaction at an equivalent Conversion Price.

- 50 -

f) Calculations. All calculations under

this Section 5 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section

5, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares

of Common Stock (excluding any treasury shares of the Company) issued and outstanding.

g) Notices to the Holder.

i. Adjustments to Conversion Price.

Whenever the Conversion Price is adjusted pursuant to any provision of this Section 5, the Company shall not later than 8:00 am

on the Trading Day following such adjustment (i) deliver to each Holder a notice setting forth the Conversion Price after such adjustment

and setting forth a statement of all of the facts requiring such adjustment and the calculation thereof, and (ii) publicly disclose the

transaction resulting in such adjustment in a filing with the SEC. Notwithstanding anything in this Section 5 to the contrary,

no adjustment pursuant to this Section 5 shall increase the Conversion Price other than proportional increases upon the occurrence

of a reverse stock split in accordance with Section 5(a). For the avoidance of doubt, the Holder will be entitled to each such

adjustment on the terms set forth in this Agreement whether or not the Company provides such notice, and the calculation set forth in

such notice shall not be binding on the Holder.

ii. Notice to Allow Conversion by

Holder. If (A) the Company shall declare a dividend (or any other distribution or other Restricted Payment in whatever form) on the

Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company

shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or purchase any shares of Capital

Stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification

of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of

the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other Securities, cash or property

or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company,

then, in each case, the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of this Note,

and shall cause to be delivered to the Holder at its last address as it shall appear upon the Note Register, at least twenty (20) calendar

days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be

taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of

which the holders of the Common Stock of record to be entitled to such dividend, distribution, Restricted Payment, redemption, rights

or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange

is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be

entitled to exchange their shares of the Common Stock for Securities, cash or other property deliverable upon such reclassification, consolidation,

merger, sale, transfer or share exchange; provided, that the failure to deliver such notice or any defect therein or in the delivery

thereof shall not affect the validity of the corporate action required to be specified in such notice. The Holder shall remain entitled

to convert this Note during the 20-day period commencing on the date of such notice through the effective date of the event triggering

such notice except as may otherwise be expressly set forth herein.

thereon.

Section

8. Miscellaneous

a) Notices. Any and all notices or other

communications or deliveries to be provided by the Holder hereunder, including any Notice of Conversion, shall be in writing and delivered

as set forth in Section 6.4 (Notices) of the Purchase Agreement. All notices and other communications delivered hereunder shall

or other obligation.

via facsimile or electronic transmission (A) if by the Company, within two (2) Trading Days after the occurrence of the circumstances

giving rise to such dispute or (B) if by the Holder at any time after the Holder learned of the circumstances giving rise to such dispute.

If the Holder and the Company are unable to promptly resolve such dispute, at any time after the second (2nd) Trading Day following

such initial notice, then the Holder may, at its sole option, select an independent, reputable investment bank to resolve such dispute.

ii. The Holder and the Company shall

each deliver to such investment bank (A) a copy of the initial dispute submission so delivered in accordance with clause d) and

Day immediately following the date on which the Holder selected such investment bank (the “Dispute Submission Deadline”)

. If either party fails to so deliver all of the Required Dispute Documentation by the Dispute Submission Deadline, then such party shall

no longer be entitled to (and hereby waives its right to) deliver or submit any document or other supporting evidence to such investment

bank with respect to such dispute and such investment bank shall resolve such dispute based solely on the Required Dispute Documentation

that was delivered to such investment bank prior to the Dispute Submission Deadline. Unless otherwise agreed to in writing by both the

Company and the Holder or otherwise requested by such investment bank, neither the Company nor the Holder shall be entitled to deliver

or submit any written documentation or other support to such investment bank in connection with such dispute other than the Required Dispute

Documentation.

ensure that such investment bank determines the resolution of such dispute and notify the Company and the Holder of such resolution no

later than ten (10) Trading Days immediately following the Dispute Submission Deadline. The fees and expenses of such investment bank

shall be borne solely by the Company, and such investment bank’s resolution of such dispute shall be final and binding upon all

parties absent manifest error.

forth in clause (d) above) and matters related hereto or arising hereunder or arising from or relating to the relationship among any of

the parties hereto, are governed by, and shall be construed, interpreted and enforced exclusively in accordance with, the laws of the

State of Delaware (without giving effect to the conflict of laws provisions thereof to the extent such principles or rules would require

or permit the application of the laws of any jurisdiction other than those of the State of Delaware). Any such Proceeding shall be brought

exclusively in the Delaware state courts sitting in Wilmington, DE or the federal courts of the United States of America for the District

of Delaware sitting in Wilmington, DE; provided, that the Collateral Agent, the Holder and the other Purchaser Parties may bring Proceedings

in other jurisdictions to enforce this Note. The parties hereto have accepted such jurisdiction and waived venue and other objections

and have agreed to the means for service of process in such Section 6.6.

f) Characterizations. The Company covenants

to the Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set

forth or provided for herein with respect to payments, conversion and the like (and the computation thereof) shall be the amounts to be

received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance

thereof).

g) Payments on Next Business Day. Whenever

any payment Obligation shall be due on a day other than a Business Day, such payment shall be due instead on the next succeeding Business

Day.

h) Payment of Collection, Enforcement and Other

Costs. In addition to, and not in substitution for and not to limit (but without duplication), any other right to reimbursement under

this Note or any other Transaction Document, (i) this Note is placed in the hands of an attorney for collection or enforcement or is collected

or enforced through any Proceeding or the Holder otherwise takes action to collect amounts due under this Note or to enforce the provisions

of this Note or (ii) there occurs any bankruptcy, reorganization, receivership of the Company or other Proceedings affecting Company creditors’

rights and involving a claim under this Note, then the Company shall pay all out-of-pocket costs incurred by the Holder for such collection,

purchase of this Note and the other Purchased Securities shall be used as provided in the Purchase Agreement.

k) Non-Public Information. Except with respect

to the Transaction Documents and the transactions contemplated thereunder, which shall be disclosed as provided in the Purchase Agreement,

each Company Party covenants and agrees that neither it, nor any other Person acting on its behalf has provided nor will provide the Holder

or its agents or counsel with any information that constitutes, or the Company reasonably believes constitutes, material non-public information,

unless prior thereto the Holder shall have consented to the receipt of such information and agreed with the Company to keep such information

confidential. Any non-disclosure agreement entered into with the Holder and any Company Party are terminated as provided in Section

4.9 (Securities Laws Disclosures) of the Purchase Agreement. The Holder does not have any duty of confidentiality (or a duty not to

trade on the basis of material non-public information) to any Company Party or any of their Affiliates, or any of their respective officers,

directors, agents, members, stockholders, managers, employees and is governed only by application Regulations. Each Company Party understands

and confirms that the Holder shall be relying on all of the foregoing covenants in trading Securities of the Company.

- 56 -

l) Public Disclosures. The Company Parties

and the Holder shall consult with each other in issuing any other public disclosure with respect to the transactions contemplated hereby,

and no Company Party or the Holder shall issue any such public disclosure nor otherwise make any such public statement without the prior

consent of the Company and the Holder, each of which consent shall not unreasonably be withheld or delayed, except if such disclosure

is reasonably viewed as required by any Regulation, in which case the disclosing party shall promptly provide the other party with prior

notice of such public statement or communication. Notwithstanding the foregoing, no Company Party shall, and each Company Party shall

ensure that their Subsidiaries do not, publicly disclose the name, trademark, service mark, symbol, logo (or any abbreviation, contraction

or simulation thereof) of, or otherwise refer to, the Holder or any other Purchaser Party (including in any filing with the SEC, regulatory

agency or Trading Market for any Securities of any Company Party or their Subsidiaries, including the 8-K filing referenced above) without

the prior consent of the Holder and the Collateral Agent (including in any press release, letterhead, public announcement or marketing

material), except, and then only after consulting with such Holder and the Collateral Agent, to the extent required to do so under applicable

Regulations (including as required in any registration statement filed with the SEC). None of the Company Parties and their Affiliates

shall represent that any Company Party or any of its Affiliates, any product or service of the Company Parties or their Affiliates, or

any know how or policy or practice of the Company Parties or their Affiliates has been approved or endorsed by any Purchaser Party.

m) Interpretation. This Note is a Transaction

Document and as such is subject to various interpretative, amendment and third party beneficiary and other miscellaneous provisions set

thereof (including Section 4.9 (Securities Law Disclosures) which, among other things, restrict public disclosures of the name

of the Holder, Section 6.15 (Interpretation) that provides, among other things, that payments due on a day that is not a Business

amended, supplemented or otherwise modified except in accordance with Section 6.3(b) (Amendments) of the Purchase Agreement and

(ii) as described in Section 6.3(a) (Entire Agreement) of the Purchase Agreement, this Note and the other Transaction Documents

contain and constitute the entire agreement of the parties with respect to the subject matter hereof. Any Holder also benefits from various

provisions of the Purchase Agreement applicable to “Purchasers” (whether by virtue of being an “Initial Purchaser”

or successor in interest thereto) and agrees to be bound by the provisions of the Purchase Agreement applicable to it in such capacity,

including Article V (Collateral Agent) thereof that describes its relationship with the Collateral Agent and contains an indemnification

provision in Section 5.9 (Indemnification) thereof. Finally, in addition to these provisions, unless otherwise expressly provided

in any Transaction Document, “outstanding” when referring in any Transaction Document to the principal amount owing

under this Note shall mean “outstanding and unconverted.”

n) Beneficiaries; Successors and Assigns.

As provided in Section 6.3(c) (Beneficiaries; Successors and Assigns) of the Purchase Agreement, this Note shall be binding upon

the successors and assigns of the Company and shall inure solely to the benefit of the Holder, each Company Party, the Collateral Agent,

each of their Purchaser Parties and their respective successors and, if permitted, assigns; provided, that no Company Party may

assign any part of this Note, or any right, obligation, benefit, title or interest hereunder except as authorized in the Purchase Agreement.

(e) (Counterparts) and (f) (Electronic Signatures) of Section 6.3 of the Purchase Agreement, this Note may be executed in any

number of counterparts, which may be signed and transmitted electronically.

p) Severability. As provided in Section

6.7 (Severability) of the Purchase Agreement, any provision of this Note being held illegal, invalid or unenforceable in any jurisdiction

shall not affect any part of such provision not held illegal, invalid or unenforceable, any other provision of this Note or any part of

such provision in any other jurisdiction, so long as the economic or legal substance of the transaction contemplated hereby is not affected

in any manner adverse to any party.

q) Waiver of Jury Trial. As provided in Section

6.16 (Waiver of Jury Trial and Certain Other Rights), each party hereto has irrevocably and unconditionally waived, to the fullest extent

permitted by applicable Regulations, trial by jury of any claim or cause of action or in any Proceeding, directly or indirectly with respect

to, or directly or indirectly based upon or arising out of, under or in connection with this Note or any other Transaction Document or

the transactions contemplated therein or related thereto (whether founded in contract, tort or any other theory). Each party hereto

(A) certifies that no other party, no Purchaser Party and no Affiliate of any of them and no attorney, agent or other representative of

any of the foregoing has represented, expressly or otherwise, that any Person would not, in the event of litigation, seek to enforce the

foregoing waiver and (B) acknowledges that it and the other parties hereto have been induced to enter into this Note by, among other things,

the mutual waivers and certifications in this Section 8(q).

SECTION 2. REPAYMENT

date as this Note is required or permitted to be repaid as provided hereunder, in each case together with all accrued but unpaid interest

thereon and all other Obligations (as defined below). In addition, the Company shall pay in full on the Maturity Date all remaining Obligations

then outstanding.

b) Mandatory Prepayments.

On the next Business Day following the Company consummating any public or private offering or any other issuance of any Capital Stock

or any other issuance of any Capital Stock (other than any issuance of Common Stock to the general public), Stock Equivalents or of any

other Securities or Indebtedness (including entering into any Equity Line of Credit or issuing any Variable-Priced Equity-Linked Instrument)

or any other debt or equity financing or capital-raising transaction of any kind (each, a “Subsequent Offering”) on

any date other than the Maturity Date, the Company shall, subject to the Holder’s conversion rights set forth herein, to repay the

Obligations pay to the Holder in cash an amount equal (each, a “Mandatory Prepayment Amount”) (i) in the case of a

Subsequent Offering other than an Equity Line of Credit, 50% of the net proceeds of such Subsequent Offering and (ii) in the case of Subsequent

Offering that is an Equity line of Credit, 50% of the net proceeds, with respect to shares of Common Stock registered under the registration

statement on Form S-1 (File No. 333-290805) or 50.0% of the net proceeds, with respect to shares of Common Stock registered under any

registration statement on Form S-1 filed after the date hereof). The Holder may continue to convert the principal amounts to be prepaid

under this Note until the date of consummation of such Subsequent Offering. This Section 2(b) is merely a requirement to redeem this Note

and not an authorization to consummate any Subsequent Offering otherwise prohibited by the Transaction Documents.

c) Voluntary Prepayments.

So long as no Default or Event of Default exists, at any time upon ten (10) Business Days’ prior written notice to the Holder (which

notice shall be a Transaction Document and constitute an irrevocable agreement to pay such amount on the date set forth on such notice)

stating the proposed date and proposed principal amount of such prepayment, but subject to the Holder’s conversion rights set forth

herein, the Company may prepay any portion of the principal amount of this Note, any accrued and unpaid interest, and any other amounts

due under this Note. If the Company exercises its right to prepay the Note, instead of such principal amount, the Company shall pay to

the Holder in cash an amount equal to the full Optional Prepayment Amount for such principal amount prepaid. The Holder may continue to

convert the principal amount of the Note to be prepared after the date notice of the prepayment is given until the date it receives such

Optional Prepayment Amount in full in cash.

7

d) Interest. The Company

shall pay interest to the Holder on the aggregate then-outstanding principal amount of this Note (and the then-outstanding principal amount

of any other Obligation owing that does not expressly provide for any other rate of interest), which shall accrue daily at the rate of

twelve percent (12%) per annum from the date this Note is issued (or in the case of any other Obligation, from the date such obligation

becomes due and payable) through the date such principal amount or other Obligation is paid in full; provided, that the Minimum

Interest Amount shall be fully earned and accrued on the Original Issue Date. Accrued interest shall replace and not add to the Minimum

Interest Amount and all payments of such accrued interest shall cause a corresponding reduction in any remaining Minimum Interest Amount.

Accrued and unpaid interest shall be due and payable in cash on the first day of each calendar month and on the Maturity Date, or as otherwise

set forth herein. Any interest accrued and unpaid on any principal amount, and any remaining Minimum Interest Amount on such principal

amount, shall be due and payable upon any repayment of such principal amount under this Note. Upon an Event of Default, the interest rate

set forth hereunder shall increase as provided in clause (e) below. The Minimum Interest Amount is intended to compensate the Holder

for a lesser profit in case of early repayment and for the internal and external work and expenditure of time and money involved in the

evaluation and preparation of the Transaction Documents and the consummation of the transactions contemplated thereunder. The Minimum

Interest Amount is not to be construed to cover or be applied against any indemnity or any out-of-pocket fees, costs or expenses incurred

in any action to collect any Obligation or to foreclose any Lien securing the same. This provision shall not affect or limit the Holder’s

rights or remedies with respect to any Event of Default.

e) Default Rate. Immediately

on and after the occurrence of any Event of Default, without need for notice or demand all of which are waived, interest on this Note

shall, in whole, automatically and without the need for any notice, demand or any other action by the Collateral Agent or the Holder all

of which are hereby waived, accrue and be owed daily at an increased interest rate equal to the lower of the Default Rate or the maximum

rate permitted under applicable Regulations. If an Event of Default (after giving effect to notice periods and grace periods) occurs,

the Default Rate shall become effective as of the date the Default that because such Event of Default first occurred, without consideration

for any notice provision or grace period.

f) Late Fee. The Company

shall pay a late fee (each a “Late Fee”) on any Obligation that is not paid when due (after taking into account applicable

grace periods set forth in Section 7(a)(i) hereof), in an amount equal to ten percent (10%) of such payment, to the Person owed such Obligation.

This Late Fee shall be due and payable immediately upon such failure. It is intended to cover the inconvenience and additional internal,

administrative and other fees, costs and expenses involved in processing delinquent payments and is not to be construed to cover or be

applied against any indemnity or any out-of-pocket fees, costs or expenses incurred in any action to collect any Obligation or to foreclose

any Lien securing the same. This provision shall not affect or limit the Holder’s rights or remedies with respect to any Event of

Default. This obligation to pay a Late Fee is a separate obligation and, once it has arisen hereunder, a failure to pay such Late Fee

will not be cured implicitly by any waiver of any Event of Default or similar event that may have caused the payment that gave rise to

such Late Fee.

g) Cash Payment Fee.

The Company shall pay a cash payment fee (each a “Cash Payment Fee”) in an amount equal to five percent (5%) of the

amount of any repayment of the principal amount of this Note that is made in cash at any time when (i) the Company shall not have received

a notice from the Holder or the Collateral Agent that an Event of Default exists, or (ii) the Company shall have received such a notice

and such Event of Default shall have been cured to the satisfaction of the Holder. This Cash Payment Fee shall be due and payable together

with such repayment and is intended to cover any loss in revenues resulting from such repayment being made in cash instead of using Common

Stock, as well as other internal costs and expenses and is not to be construed to cover or be applied against any indemnity or any out-of-pocket

fees, costs or expenses incurred in any action to collect any Obligation or to foreclose any Lien securing the same. The Cash Payment

Fee shall not be applicable to the payment of any Mandatory Prepayment Amount. This provision shall not affect or limit the Holder’s

rights or remedies with respect to any Event of Default. This obligation to pay a Cash Payment Fee is a separate obligation hereunder

and, once arisen, shall be owed regardless of whether such payment is later returned, reversed, forgiven, waived or voided.

8

h) Calculations and Payment

Provisions. All payments made to the Holder, the Collateral Agent and their Purchaser Parties under any Transaction Document, except

as otherwise expressly provided in any Transaction Document, shall be made in cash, which shall mean in immediately available dollars

and without set off or counterclaim. Interest and fees owing to any of them shall be calculated on the basis of a 360-day year consisting

of twelve thirty (30)-day periods, for the actual number of days occurring, in whole or in part, in the applicable period. The Holder

(or, for payments owing to it, the Collateral Agent) shall have the option to refuse or accept, in their sole discretion, any payment

to the Collateral Agent, the Holder or their Purchaser Parties attempted to be made without a required notice, without a required Optional

Prepayment Amount, a Minimum Interest Amount or a required fee. The Holder (or, for payments owing to the Collateral Agent, the Collateral

Agent) may, in its sole discretion, apply or recharacterize any payment made under any Transaction Document to the payment of any outstanding

Obligation, regardless of the intended characterization thereof by any Company Party, including by recharacterizing a payment of principal

made to a payment of an Optional Prepayment Amount, a Minimum Interest Amount or a required fee, even if this characterization results

in a smaller payment of principal. The Company hereby irrevocably waives the right to direct the application of any payment (or, after

any Event of Default, any proceeds of Collateral) to any Obligation. Whenever any payment under any Transaction Document shall be stated

to be due on a day other than a Business Day, such payment shall be due on the next succeeding Business Day, including for purposes of

the calculation of interest and fees. Any payment of any Obligation received by the Holder, the Collateral Agent or any Purchaser Party

after 3 p.m. on any day shall be deemed received on the next Business Day. Each determination by the Holder (or, for payments owing to

it, the Collateral Agent) of an amount of interest or fee due hereunder shall be conclusive and binding for all purposes, absent manifest

error.

Section

3. Registration of Transfers and Exchanges

a) Different Denominations.

This Note is exchangeable for an equal aggregate principal amount of Notes of different authorized denominations, as requested by

the Holder surrendering the same. No service charge will be payable for such registration of transfer or exchange.

b) Investment Representations.

This Note has been issued subject to certain investment representations of the original Holder and may be transferred or exchanged

only in compliance with applicable federal and state securities Regulations.

c) Reliance on Note Register.

The Company shall maintain in its records a list of the Holders and of registration and transfers of the Note (the “Note

Register”). The initial Holder is listed herein. Any Holder may later notify in writing the Company of an assignment or transfer

and the Company shall notify such transfer in the Note Register. Failure by the Company to duly notify such transfer in the Note Register

shall not affect the validity of such assignment or transfer. Nevertheless, if the Company has not received notice of any transfer of

this Note, the Company and any agent of the Company may treat the Person in whose name this Note is duly registered as the owner hereof

for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Note is overdue. Upon request

by the Holder, the Company shall immediately execute and deliver to such Holder replacement Note or Notes, which may involve executing

multiple Notes with split amounts to reflect partial assignments. Promptly upon receipt of such replacement Note or Notes, such Holder

shall deliver the original Note back to the Company or, if the original Note is lost or stolen, provide an affidavit to the Company to

that effect.

Section

4. Conversion

a) Voluntary Conversion.

At any time after the Original Issue Date, all Obligations with respect to this Note shall be convertible, in whole or in part, into shares

of Common Stock at the option of the Holder, in its sole discretion, at any time and from time to time (subject to the conversion limitations

set forth in Section 4(d)). The Holder shall effect conversions by delivering to the Company a Notice of Conversion, the form of

which is attached hereto as Annex A (each, a “Notice of Conversion”), specifying therein the amount of such

Obligations to be converted and the date on which such conversion shall be effected (such date, the “Conversion Date”).

If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion is

deemed delivered hereunder. No ink-original Notice of Conversion shall be required, nor shall any medallion guarantee (or other type of

guarantee or notarization) of any Notice of Conversion form be required. To effect conversions hereunder, the Holder shall not be required

to physically surrender this Note to the Company unless the entire principal amount of this Note, plus all accrued and unpaid interest

thereon, has been converted. Conversions hereunder shall have the effect of lowering the outstanding principal amount of this Note by

an amount equal to the applicable conversion. The Holder and the Company shall maintain a Conversion Schedule, containing at a minimum

the information shown on Schedule 1, and showing historically, among other things, the principal amounts converted and the date

of such conversions. The Company may deliver an objection to any Notice of Conversion within one (1) Business Day of delivery of such

Notice of Conversion. In the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in

the absence of manifest error.

9

b) Conversion Price.

Subject to the other provisions of this Note, the conversion price in effect on any Conversion Date (the “Conversion Price”)

shall be equal to $0.50, subject to adjustment as provided herein; provided, that in no event shall the Conversion Price be less than

the Floor Price.

c) Mechanics of Conversion.

i. Conversion

Shares Issuable Upon Conversion of Principal Amount. The number of Conversion Shares issuable upon a conversion hereunder shall be

determined by the quotient obtained by dividing (x) the outstanding principal amount and interest of this Note to be converted by (y)

the Conversion Price.

ii. Delivery

of Certificate Upon Conversion. Not later than one (1) Trading Day after each Conversion Date (the “Share Delivery Date”),

the Company shall deliver, or cause to be delivered, to the Holder a certificate or certificates representing the Conversion Shares which,

on or after the date on which such Conversion Shares are eligible to be sold under Rule 144 without the need for current public information

and the Company has received an opinion of counsel to such effect, which such opinion must be acceptable to the Holder in its sole and

absolute discretion (which opinion the Company shall be responsible for obtaining at its sole cost and expense) shall be free of restrictive

legends and trading restrictions, representing the number of Conversion Shares being acquired upon the conversion of this Note. Each certificate

required to be delivered by the Company under this Section 4(c) shall be delivered electronically through the Depository Trust

Company or another established clearing corporation performing similar functions. If the Conversion Date is prior to the date on which

such Conversion Shares are eligible to be sold under Rule 144 without the need for current public information, or there is no registration

statement in effect covering the Conversion Shares, the Conversion Shares shall bear a restrictive legend in the following form, as appropriate:

“THE ISSUANCE AND SALE OF THE

SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE

SECURITIES REGULATIONS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE

REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL (WHICH COUNSEL SHALL

BE SELECTED BY THE HOLDER), IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT

TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN

ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.”

Notwithstanding the foregoing, commencing

on such date that the Conversion Shares are eligible for sale under Rule 144 subject to current public information requirements, the Company,

upon written request and at the sole cost and expense of the Company, shall obtain a legal opinion that is acceptable to the Holder in

its sole and absolute discretion, to allow for such sales under Rule 144.

10

iii. Reservation

of Conversion Shares. The Company covenants that it will at all times reserve and keep available out of its authorized and unissued

shares of Common Stock a number of shares of Common Stock at least equal the Reserve Amount for the sole purpose of issuance upon conversion

of this Note and payment of interest on this Note, each as herein provided, free from preemptive rights or any other actual contingent

purchase rights of Persons other than the Holder (and the other holders of the Purchase Agreement Notes). The Company covenants that all

shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and nonassessable.

The Company shall calculate and readjust the Reserve Amount on the first Business Day of each month so long as any Purchased Security

remains outstanding.

iv. Fractional

Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of this Note. As to any fraction

of a share which the Holder would otherwise be entitled to purchase upon such conversion, the Company shall at its election, either pay

a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Conversion Price or round up

to the next whole share.

v. Transfer Taxes

and Expenses. The issuance of certificates for shares of the Common Stock on conversion of this Note shall be made without charge

to the Holder hereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificates,

provided, that, the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the

issuance and delivery of any such certificate upon conversion in a name other than that of the Holder of this Note so converted and the

Company shall not be required to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof

shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been

paid. The Company shall pay all Transfer Agent fees required for same-day processing of any Notice of Conversion

vi. Failure to

Deliver Certificates. If, in the case of any Notice of Conversion, such certificate or certificates are not delivered to or as directed

by the applicable Holder by the Share Delivery Date, the Holder shall be entitled to elect by written notice to the Company at any time

on or before its receipt of such certificate or certificates, to rescind such Conversion, in which event the Company shall promptly return

to the Holder any original Note delivered to the Company and the Holder shall promptly return to the Company the Common Stock certificates

issued to the Holder pursuant to the rescinded Notice of Conversion.

vii. Obligation

Absolute; Partial Liquidated Damages. The Company’s obligations to issue and deliver the Conversion Shares upon conversion of

this Note in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to

enforce the same, the existence of any Default or Event of Default, any waiver or consent with respect to any provision hereof, the recovery

of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination,

or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation

of Regulations by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation

of the Company to the Holder in connection with the issuance of such Conversion Shares; provided, that such delivery shall not

operate as a waiver by the Company of any such action the Company may have against the Holder. In the event the Holder of this Note shall

elect to convert any or all of the outstanding principal or interest amount hereof, the Company may not refuse conversion based on any

claim that the Holder or anyone associated or affiliated with the Holder has been engaged in any violation of Regulation, Contractual

Obligation or for any other reason, unless an injunction from a court, on notice to Holder, restraining and or enjoining conversion of

all or part of this Note shall have been sought. If the injunction is not granted, the Company shall promptly comply with all conversion

obligations herein. If the injunction is obtained, the Company must post a surety bond for the benefit of the Holder in the amount of

one hundred fifty percent (150%) of the outstanding principal amount of this Note, which is subject to the injunction, which bond shall

remain in effect until the completion of arbitration/litigation of the underlying dispute and the proceeds of which shall be payable to

the Holder to the extent it obtains judgment. In the absence of seeking such injunction, the Company shall issue Conversion Shares (or,

where applicable and required hereunder, cash), upon a properly noticed conversion. If the Company fails for any reason to deliver to

the Holder such certificate or certificates pursuant to Section 4(c)(ii) by the Share Delivery Date, the Company shall pay to the

Holder, in cash, as liquidated damages and not as a penalty, $1,000 per Trading Day for each Trading Day after such Share Delivery Date

until such certificates are delivered or Holder rescinds such conversion. Nothing herein shall limit a Holder’s right to pursue

actual damages or declare an Event of Default pursuant to Section 7 for the Company’s failure to deliver Conversion Shares

within the period specified herein and the Holder shall have the right to pursue all remedies available to it hereunder, at law or in

equity including a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit the Holder

from seeking to enforce damages pursuant to any other Section hereof or under applicable Regulation.

11

viii. Compensation

for Buy-In on Failure to Timely Deliver Certificates Upon Conversion. In addition to any other rights available to the Holder, if

the Company fails for any reason to deliver to the Holder such certificate or certificates by the Share Delivery Date pursuant to Section

4(c)(ii), and if after such Share Delivery Date the Holder is required by its brokerage firm to purchase (in an open market transaction

or otherwise), or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by

the Holder of the Conversion Shares which the Holder was entitled to receive upon the conversion relating to such Share Delivery Date

(a “Buy-In”), then the Company shall (A) pay in cash to the Holder (in addition to any other remedies available to

or elected by the Holder) the amount, if any, by which (x) the Holder’s total purchase price (including any brokerage commissions)

for the Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that the Holder was entitled

to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation

was executed (including any brokerage commissions) and (B) at the option of the Holder, in its sole discretion, either reissue (if surrendered)

this Note in a principal amount equal to the principal amount of the attempted conversion (in which case such conversion shall be deemed

rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued if the Company had timely complied

with its delivery requirements under Section 4(c)(ii). For example, if the Holder purchases Common Stock having a total purchase

price of $11,000 to cover a Buy-In with respect to an attempted conversion of this Note with respect to which the actual sale price of

the Conversion Shares (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause

(A) of the immediately preceding sentence, the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company

written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the

amount of such loss. Nothing herein shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law

or in equity including a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely

deliver certificates representing shares of Common Stock upon conversion of this Note as required pursuant to the terms hereof.

ix. No Limitation

on Damages. More generally, nothing in this Section 4, including the availability of the option to convert the Note, shall

limit the Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section 7 and the Holder shall

have the right to pursue all remedies available to it hereunder, at law or in equity including a decree of specific performance and/or

injunctive relief. The exercise of any rights under this Section 4 shall not prohibit the Holder from seeking to enforce damages

pursuant to any other Section hereof or under applicable Regulation.

d) Holder’s Conversion

Limitations. The Company shall not effect any conversion of principal or interest of this Note, and the Holder shall not have the

right to convert any principal or interest of this Note, to the extent that after giving effect to the conversion set forth on the applicable

Notice of Conversion, the Holder (together with the Holder’s Affiliates, and any Persons acting as a group together with the Holder

or any of the Holder’s Affiliates, the “Attribution Parties”) would beneficially own in excess of the Beneficial

Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned

by the Holder and its Attribution Parties shall include the number of Conversion Shares issuable upon conversion of this Note with respect

to which such determination is being made, but shall exclude the number of shares of Common Stock issuable upon (i) conversion of the

remaining, unconverted principal amount of this Note beneficially owned by the Holder or any of its Attribution Parties and (ii) exercise

or conversion of the unexercised or unconverted portion of any other Securities of the Company subject to a limitation on conversion or

exercise analogous to the limitation contained herein (including any other Notes) beneficially owned by the Holder or any of its Attribution

Parties. Except as set forth in the preceding sentence, for purposes of this Section 4(d), beneficial ownership shall be calculated

in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation

contained in this Section 4(d) applies, the determination of whether this Note is convertible (in relation to other Securities

owned by the Holder together with any Attribution Parties) and of which principal amount of this Note is convertible shall be in the sole

discretion of the Holder, and the submission of a Notice of Conversion shall be deemed to be the Holder’s determination of whether

this Note may be converted (in relation to other Securities owned by the Holder together with any Attribution Parties) and which principal

amount of this Note is convertible, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction,

the Holder will be deemed to represent to the Company each time it delivers a Notice of Conversion that such Notice of Conversion has

not violated the restrictions set forth in this paragraph and the Company shall have no obligation to verify or confirm the accuracy of

such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section

13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 4(d), in determining

the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as stated in

the most recent of the following: (i) the Company’s most recent periodic or annual report filed with the SEC, as the case may be,

(ii) a more recent public announcement by the Company, or (iii) a more recent written notice by the Company or the Company’s transfer

agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of the Holder, the Company shall

within two (2) Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any

case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of Securities

of the Company, including this Note, by the Holder or its Attribution Parties since the date as of which such number of outstanding shares

of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common

Stock outstanding immediately after giving effect to the issuance of all Conversion Shares to be held by the Holder. The Holder, upon

not less than sixty-one (61) days’ prior notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions

of this Section 4(d); provided, that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares

of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon conversion of this Note

held by the Holder. Any such increase or decrease will not be effective until the sixty-first (61st) day after such notice

is delivered to the Company. The Beneficial Ownership Limitation provisions of this paragraph shall be construed and implemented in a

manner otherwise than in strict conformity with the terms of this Section 4(d) to correct this paragraph (or any portion hereof)

which may be defective or inconsistent with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements

necessary or desirable to properly give effect to such limitation. The limitations contained in this Section 4(d) shall apply to

a successor Holder of this Note.

12

e) Exchange Cap. The

Company shall not issue any shares of Common Stock upon conversion of this Note or otherwise pursuant to the terms of this Note if the

issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue upon conversion

of this Note or otherwise pursuant to the terms of this Note without breaching the Company’s obligations under the rules or regulations

of the Principal Trading Market for the Common Stock (the number of shares which may be issued without violating such rules and regulations,

the “Exchange Cap”), except that such limitation shall not apply in the event that the Company (i) obtains the approval

of its stockholders as required by the applicable rules of such Principal Trading Market for issuances of shares of Common Stock in excess

of such amount or (ii) obtains a written opinion from outside counsel to the Company that such approval is not required, which opinion

shall be in form and substance reasonably satisfactory to the Holder. Until such approval or such written opinion is obtained, the Holder

shall not be issued in the aggregate, upon conversion of this Note or otherwise pursuant to the terms of this Note, shares of Common Stock

in an amount greater than the product of (A) the Exchange Cap as of the proposed date of issuance for such shares multiplied by (B) the

quotient of (1) the aggregate original Principal Amount of this Note when issued to the applicable Purchaser pursuant to the Purchase

Agreement divided by (2) the aggregate original Principal Amount of all Purchase Agreement Notes when issued (the “Exchange Cap

Allocation”). In the event that the Holder sells or otherwise transfer any portion of this Note, the transferee shall be allocated

a pro rata portion of the Holder’s Exchange Cap Allocation with respect to such portion of this Note so transferred, and the restrictions

of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation so allocated to such transferee.

Upon conversion in full of any holder of any Purchase Agreement Note, the difference (if any) between such holder’s “exchange

cap allocation” (under and as defined in such Purchase Agreement Note) and the number of shares of Common Stock actually issued

to such holder upon such holder’s conversion in full of any Purchase Agreement Note shall be allocated to the respective Exchange

Cap Allocations of the remaining holders of such Purchase Agreement Notes (including the Holder) on a pro rata basis in proportion to

the shares of Common Stock underlying such Purchase Agreement Notes then held by each such holder. In the event that the Company is prohibited

from issuing any shares of Common Stock pursuant to this Section 4(e)(the “Exchange Cap Shares”) to the Holder,

the Company shall pay cash to the Holder in exchange for the redemption of such portions of this Note that are not convertible into such

Exchange Cap Shares at a price equal to the sum of (A) the product of (1) such number of Exchange Cap Shares and (2) the Closing Sale

Price on the Trading Day immediately preceding the date the Holder delivers the applicable Notice of Conversion with respect to such Exchange

Cap Shares to the Company, and (B) to the extent the Holder purchases (in an open market transaction or otherwise) shares of Common Stock

to deliver in satisfaction of a sale by the Holder of Exchange Cap Shares, brokerage commissions, if any, of the Holder incurred in connection

therewith.

Section

5. Certain Adjustments

a) Stock Dividends and

Stock Splits. If the Company, at any time while this Note is outstanding: (i) pays a stock dividend or otherwise makes a Restricted

Payment payable in shares of Common Stock on shares of Common Stock or any Stock Equivalents (which, for avoidance of doubt, shall not

include any shares of Common Stock issued by the Company upon conversion of, or payment of interest on, this Note), (ii) subdivides outstanding

shares of Common Stock into a larger number of shares, (iii) combines (including by way of a reverse stock split) outstanding shares of

Common Stock into a smaller number of shares or (iv) issues, in the event of a reclassification of shares of the Common Stock, any shares

of capital stock of the Company, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number

of shares of Common Stock (excluding any treasury shares of the Company) outstanding immediately before such event, and of which the denominator

shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section

5(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend

or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

b) Change in Option Price

or Rate of Conversion. If the purchase or exercise price provided for in any options to purchase Common Stock, the additional consideration,

if any, payable upon the issue, conversion, exercise or exchange of any Stock Equivalents into Common Stock, or the rate at which any

Stock Equivalents are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time (other

than any change to the Conversion Price in this Note or any changes to the exercise price in the Warrants), the Conversion Price in effect

at the time of such increase or decrease shall be adjusted to account proportionately, for such increase or decrease. For purposes of

this Section 5(b), if the terms of any option or Stock Equivalents are increased or decreased in the manner described in the immediately

preceding sentence, then such option or Stock Equivalents and the shares of Common Stock deemed issuable upon exercise, conversion or

exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section

5(b) shall be made to the Conversion Price if such adjustment would result in an increase to the Conversion Price.

c) Subsequent Equity Sales.

If any Company Party or any Subsidiary thereof, at any time while any Obligation is outstanding or the Holder has not yet received any

Conversion Shares in connection with a conversion, shall sell or grant any option to purchase, or sell or grant any right to reprice,

or otherwise dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any shares of Common

Stock or Stock Equivalents convertible or exchangeable into Common Stock, in each case other than as an Exempt Issuance, at an effective

price per share that, after giving effect to any other adjustment provided in this Note, is less than the Conversion Price then in effect

(such lower price, the “Base Share Price” and such issuances collectively, a “Dilutive Issuance”)

then, simultaneously with the consummation of each Dilutive Issuance the Conversion Price shall be reduced and only reduced to equal the

Base Share Price. For the avoidance of doubt, it is understood and agreed that if a holder of the shares of Common Stock or Stock Equivalents

so issued shall, at any time after the issuance, whether by operation of purchase price adjustments, reset provisions, floating conversion,

exercise or exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance,

be entitled to receive shares of Common Stock at an effective price per share that is less than the Conversion Price, such issuance shall

be deemed to have occurred for less than the Conversion Price on such date of the Dilutive Issuance at such effective price. Such adjustment

shall be made whenever such shares of Common Stock or Stock Equivalents are issued. No later than 8:00 am on the Trading Day following

the issuance or deemed issuance of any shares of Common Stock or Stock Equivalents subject to this Section 5(c), the Company shall

(i) notify the Holder, in writing, indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion

price and other pricing terms (such notice, the “Dilutive Issuance Notice”) and (ii) publicly disclose the transaction

resulting in such issuance or deemed issuance in a filing with the SEC. For purposes of clarification, whether or not the Company provides

a Dilutive Issuance Notice pursuant to this Section 5(c), upon the occurrence of any Dilutive Issuance, the Holder is entitled

to receive a number of Conversion Shares based upon the Base Share Price regardless of whether the Holder accurately refers to the Base

Share Price in the Notice of Conversion.

13

d) Pro Rata Distributions.

While this Note is outstanding, the Company shall not declare or make any Restricted Payment (or rights to receive Restricted Payments).

In the event that the Note is repaid at the time of such Restricted Payment, the Holder shall not be entitled to participate in such Restricted

Payment. If the Holder and the Company mutually agree, and the Note is not repaid at the time of such Restricted Payment, then the Holder

shall be entitled to participate in such Restricted Payment to the same extent that the Holder would have participated therein if the

Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Note (without regard to any limitations

on exercise hereof, including the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Restricted

Payment, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the

participation in such Restricted Payment (provided, that to the extent that the Holder’s right to participate in any such

Restricted Payment would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to

participate in such Restricted Payment to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such

Restricted Payment to such extent) and the portion of such Restricted Payment shall be held in abeyance for the benefit of the Holder

until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

e) Effect of Fundamental

Transactions. Upon the occurrence of any Fundamental Transaction, the Holder, upon any subsequent conversion of this Note, shall have

the right to receive, for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence

of such Fundamental Transaction (without regard to any limitation in Section 4(c) on the conversion of this Note), any consideration

receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Note is convertible

(or holder of any equity Securities of any Company Party) immediately prior to such Fundamental Transaction (without regard to any limitation

in Section 4(c) on the conversion of this Note) (the “Alternate Consideration”), including shares of Common

Stock of any successor or acquiring corporation or of the Company, in the case of a merger where it is the surviving entity. To the extent

such Alternate Consideration includes Securities, the Holder shall have the option to either treat the Note as converted on the date of

consummation of such Fundamental Transaction and obtain such Securities outright or adjust the Conversion Shares to include such additional

Securities. For purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to

such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental

Transaction, and the Company Parties shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting

the relative value of any different components of the Alternate Consideration. In a Fundamental Transaction where holders of Common Stock

(or, as the case may be, Securities of any Company Party) are given any choice as to the Alternate Consideration to be received in a Fundamental

Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this

Note following such Fundamental Transaction. The Company shall cause any acquiring, successor, surviving or replacement entities in any

Fundamental Transaction (the “Successor Entity”) to become a Company Party effective immediately upon the consummation

of such Fundamental Transaction and shall become a party to all Transaction Documents in the same capacity and to the same extent as the

Company Party involved in such Fundamental Transaction and, if such Fundamental Transaction involves the Company, from and after the date

of such Fundamental Transaction, the provisions of this Note and the other Transaction Documents referring to the “Company”

shall, without any further action, refer instead to the Successor Entity or to both Companies, as appropriate. In the case of a Fundamental

Transaction resulting in the Company no longer be in existence, the Successor Entity shall succeed to all obligations of the Company and

may exercise every right and power of the Company and shall assume all of the Obligations of the Company with the same effect as if such

Successor Entity had been named as the Company herein. The parties hereto shall amend all Transaction Documents (or execute new Transaction

Documents, including replacement Notes and an assumption of the Company’s Obligations) to reflect such change; provided that

the failure to amend or execute any such Transaction Document shall not render this clause (e) ineffective. For the avoidance of

doubt, this clause (e) is not intended to permit any Fundamental Transaction. The Company shall ensure that the Holder approves

all drafts of such amendments and new Transaction Documents prior to the consummation of, and as a condition to the consummation of, such

Fundamental Transaction. Without limitation, if the Fundamental Transaction involves the Company, the definition of Conversion Shares

and Conversion Price hereunder shall be adjusted to include Securities of the Successor Entity and to ensure the new Notes of the Holder

convert into Securities so as to protect the economic value of this Note, taking into account the relative values of the existing and

replacement Conversion Shares, and give the Holder upon conversion of this Note the Conversion Shares equivalent to the Conversion Shares

it would have received upon conversion of this Note prior to such Fundamental Transaction at an equivalent Conversion Price.

14

f) Calculations. All

calculations under this Section 5 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For

purposes of this Section 5, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be

the sum of the number of shares of Common Stock (excluding any treasury shares of the Company) issued and outstanding.

g) Notices to the Holder.

i. Adjustments

to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Section 5, the Company shall

not later than 8:00 am on the Trading Day following such adjustment (i) deliver to each Holder a notice setting forth the Conversion Price

after such adjustment and setting forth a statement of all of the facts requiring such adjustment and the calculation thereof, and (ii)

publicly disclose the transaction resulting in such adjustment in a filing with the SEC. Notwithstanding anything in this Section 5

to the contrary, no adjustment pursuant to this Section 5 shall increase the Conversion Price other than proportional increases

upon the occurrence of a reverse stock split in accordance with Section 5(a). For the avoidance of doubt, the Holder will be entitled

Section

a) Notices. Any and

all notices or other communications or deliveries to be provided by the Holder hereunder, including any Notice of Conversion, shall be

Except as expressly provided herein, no provision of this Note shall alter or impair the obligation of the Company, which is absolute

and unconditional, to pay the principal of, liquidated damages and accrued interest, as applicable, on this Note, without set off or counterclaim,

at the time, place, and rate, and in the coin or currency, herein prescribed. This Note is a direct debt obligation of the Company. This

Note ranks pari passu with all other Purchase Agreement Notes now or hereafter issued under the terms set forth in the Transaction

such Indebtedness or other obligation.

d) Dispute Resolution.

i. In the case of

a dispute relating to, or, when an agreement between the Company and the Holder is required hereunder, an inability to agree on, a Conversion

dispute relating to the determination of any of the foregoing), the Company or the Holder (as the case may be) shall submit the dispute

to the other party via facsimile or electronic transmission (A) if by the Company, within two (2) Trading Days after the occurrence of

the circumstances giving rise to such dispute or (B) if by the Holder at any time after the Holder learned of the circumstances giving

rise to such dispute. If the Holder and the Company are unable to promptly resolve such dispute, at any time after the second (2nd)

Trading Day following such initial notice, then the Holder may, at its sole option, select an independent, reputable investment bank to

resolve such dispute.

ii. The Holder and

the Company shall each deliver to such investment bank (A) a copy of the initial dispute submission so delivered in accordance with clause

supporting its position with respect to such dispute, in each case, no later than 5:00 p.m. (New York time) by the fifth (5th)

Trading Day immediately following the date on which the Holder selected such investment bank (the “Dispute Submission Deadline”)

. If either party fails to so deliver all of the Required Dispute Documentation by the Dispute Submission Deadline, then such party shall

no longer be entitled to (and hereby waives its right to) deliver or submit any document or other supporting evidence to such investment

bank with respect to such dispute and such investment bank shall resolve such dispute based solely on the Required Dispute Documentation

that was delivered to such investment bank prior to the Dispute Submission Deadline. Unless otherwise agreed to in writing by both the

Company and the Holder or otherwise requested by such investment bank, neither the Company nor the Holder shall be entitled to deliver

or submit any written documentation or other support to such investment bank in connection with such dispute other than the Required Dispute

Documentation.

iii. The Company

and the Holder shall ensure that such investment bank determines the resolution of such dispute and notify the Company and the Holder

of such resolution no later than ten (10) Trading Days immediately following the Dispute Submission Deadline. The fees and expenses of

such investment bank shall be borne solely by the Company, and such investment bank’s resolution of such dispute shall be final

and binding upon all parties absent manifest error.

Note or to enforce the provisions of this Note or (ii) there occurs any bankruptcy, reorganization, receivership of the Company or other

and agreed with the Company to keep such information confidential. Any non-disclosure agreement entered into with the Holder and any Company

any duty of confidentiality (or a duty not to trade on the basis of material non-public information) to any Company Party or any of their

Affiliates, or any of their respective officers, directors, agents, members, stockholders, managers, employees and is governed only by

application Regulations. Each Company Party understands and confirms that the Holder shall be relying on all of the foregoing covenants

in trading Securities of the Company.

l) Public Disclosures.

The Company Parties and the Holder shall consult with each other in issuing any other public disclosure with respect to the transactions

contemplated hereby, and no Company Party or the Holder shall issue any such public disclosure nor otherwise make any such public statement

such disclosure is reasonably viewed as required by any Regulation, in which case the disclosing party shall promptly provide the other

party with prior notice of such public statement or communication. Notwithstanding the foregoing, no Company Party shall, and each Company

Party shall ensure that their Subsidiaries do not, publicly disclose the name, trademark, service mark, symbol, logo (or any abbreviation,

contraction or simulation thereof) of, or otherwise refer to, the Holder or any other Purchaser Party (including in any filing with the

SEC, regulatory agency or Trading Market for any Securities of any Company Party or their Subsidiaries, including the 8-K filing referenced

above) without the prior consent of the Holder and the Collateral Agent (including in any press release, letterhead, public announcement

or marketing material), except, and then only after consulting with such Holder and the Collateral Agent, to the extent required to do

so under applicable Regulations (including as required in any registration statement filed with the SEC). None of the Company Parties

and their Affiliates shall represent that any Company Party or any of its Affiliates, any product or service of the Company Parties or

their Affiliates, or any know how or policy or practice of the Company Parties or their Affiliates has been approved or endorsed by any

Purchaser Party.

including Article V (Collateral Agent) thereof that describes its relationship with the Collateral Agent and contains an indemnification

provision in Section 5.9 (Indemnification) thereof. Finally, in addition to these provisions, unless otherwise expressly provided

in any Transaction Document, “outstanding” when referring in any Transaction Document to the principal amount owing

under this Note shall mean “outstanding and unconverted.”

and Assigns. As provided in Section 6.3(c) (Beneficiaries; Successors and Assigns) of the Purchase Agreement, this Note shall

be binding upon the successors and assigns of the Company and shall inure solely to the benefit of the Holder, each Company Party, the

p) Severability. As

provided in Section 6.7 (Severability) of the Purchase Agreement, any provision of this Note being held illegal, invalid or unenforceable

in any jurisdiction shall not affect any part of such provision not held illegal, invalid or unenforceable, any other provision of this

Note or any part of such provision in any other jurisdiction, so long as the economic or legal substance of the transaction contemplated

hereby is not affected in any manner adverse to any party.

q) Waiver of Jury Trial.

As provided in Section 6.16 (Waiver of Jury Trial and Certain Other Rights), each party hereto has irrevocably and unconditionally waived,

or indirectly with respect to, or directly or indirectly based upon or arising out of, under or in connection with this Note or any other

Transaction Document or the transactions contemplated therein or related thereto (whether founded in contract, tort or any other theory).

Each party hereto (A) certifies that no other party, no Purchaser Party and no Affiliate of any of them and no attorney, agent or other

representative of any of the foregoing has represented, expressly or otherwise, that any Person would not, in the event of litigation,

seek to enforce the foregoing waiver and (B) acknowledges that it and the other parties hereto have been induced to enter into this Note

by, among other things, the mutual waivers and certifications in this Section 8(q).

Exhibit 99.2

Profusa Expands into Multi-Billion Dollar Precision

Diagnostics Market with $30M Letter of Intent for a PanOmics Platform

Company secures scalable multi-omics diagnostics

platform and launches Mayo Clinic partnership adding to Lumee real-time biochemistry monitoring platform to advance pancreatic cancer

applications

BERKELEY, CA, April 06, 2026 (GLOBE NEWSWIRE) -- Profusa, Inc. (“Profusa” or the “Company”) (Nasdaq: PFSA), a commercial stage digital health company

pioneering the next generation of technology platform enabling the continuous monitoring of an individual’s biochemistry, today

announced a strategic expansion into molecular diagnostics through a Letter of Intent to acquire the PanOmics™ multi-omics diagnostics

platform from BioInsights LLC (“BioInsights”). The Company believes this acquisition, adding to its core real-time biochemistry

monitoring platform, will help to position Profusa at the intersection of biosensing, diagnostics, and precision medicine, establishing

a foundation for scalable multi-product diagnostics and monitoring franchise.

“This is a pivotal step in the evolution

of Profusa,” said Dr. Ben Hwang, Profusa Chairman and Chief Executive Officer. “The combination of the PanOmics platform and

our collaboration with Mayo Clinic positions us to build a differentiated, scalable presence in precision diagnostics and surgical monitoring.

The entry into pancreatic cancer is instrumental in our establishing a platform capable of supporting multiple indications and long-term

growth. With access to clinical samples, a clear validation pathway, and our

previously announced collaboration with the Mayo Clinic, one of the world’s leading medical institutions, we believe we are

uniquely positioned to accelerate development, drive clinical adoption, and unlock meaningful near-term high-growth commercial value.

Additionally, this transaction will add $30 million of shareholder equity to our balance sheet.”

Transaction Highlights

Under the terms of the Letter of Intent:

● Profusa

would acquire exclusive rights to the PanOmics platform and related know-how

● Total

consideration of approximately $30 million, to be paid in equity securities

● BioInsights

to provide access to a specified number of samples for validation

● BioInsights

to receive a 3% royalty on net revenue

● Profusa

intends to pursue additional financing to support development and scale

● BioInsights

will have the right to nominate one independent Board member for consideration by stockholders to replace an outgoing Board member

The proposed transaction remains subject to completion

of due diligence, shareholder approval, and customary closing conditions. For additional information regarding the Letter of Intent, please

refer to our Current Report on Form 8-K filed today.

Accelerated Pathway from Platform to Commercialization

As part of the proposed BioInsights transaction,

Profusa would gain exclusive access to clinically annotated samples for validation, and established assay design and infrastructure,

which it believes would create a defined pathway to rapidly validated lab developed test (LDT) commercialization. These assets are expected

to enable a capital-efficient and accelerated path from development to revenue generation.

The integration of the PanOmics platform with

Profusa’s biosensing technologies then creates a unique opportunity to develop:

● Multi-indication diagnostic assays

● Real-time physiological monitoring solutions

● Data-driven clinical decision tools

Profusa believes this combined approach can support

expansion into multiple high-growth markets and establish a scalable, recurring-revenue diagnostics and monitoring platform. This

platform will be integrated into the Company’s previously

announced, emerging vertical to address issues associated with pancreatic cancer. The Company is collaborating to leverage its Lumee®

oxygen platform to address critical intraoperative and postoperative monitoring challenges in complex pancreatic procedures. Pancreatic

cancer remains one of the most challenging surgical oncology areas, with more than 13,000 resections performed annually in the United

States, representing an estimated $26 million annual revenue opportunity.

considered “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States

Private Securities Litigation Reform Act of 1995. Forward-looking statements generally relate to future events or future financial or

operating performance of Profusa. In some cases, you can identify forward-looking statements by terminology such as “anticipate,”

“predict,” “project,” “propose,” “seek,” “should,” “strive,” “will,”

or “would” or the negatives of these terms or variations of them or similar terminology. Such forward-looking statements are

subject to risks, uncertainties, and other factors which may be beyond the control of Profusa and could cause actual results to differ

materially from those expressed or implied by such forward-looking statements including, without limitation, risks related to the Company’s

planned European and U.S. product launches, the risk that such product launches may not result in revenue at the levels anticipated, the

risk that customer demand may be less than expected, and risks relating to the Company’s withdrawal of the Registration Statement
