SENIOR SECURED CONVERTIBLE PROMISSORY NOTE

DUE JULY 3, 2026

This Senior Secured Convertible Promissory Note is duly authorized and validly issued on the date set forth above (such date, regardless of any transfers of any Note and regardless of the number of instruments which may be issued to evidence such Note, being the “Original Issue Date”) by CDT Equity Inc., a Delaware corporation, (together with any successors and, if permitted, assigns, the “Company”), designated as its Senior Secured Convertible Promissory Note due July 3, 2026 (this “Note”), and issued and sold by the Company pursuant to the Securities Purchase Agreement, dated as of March 3, 2026, by and among the Company, the other Company Parties and Ascent Partners Fund LLC (together with its successors and registered assigns, the “Holder”), a Delaware limited liability company (the “Purchase Agreement”; capitalized terms used but not otherwise defined herein are used as defined in the Purchase Agreement on the date hereof, with such amendments as may be acceptable to the Holder in its sole discretion). This Note is entered into pursuant to the Purchase Agreement and is subject to the terms and conditions thereof.

FOR VALUE RECEIVED, the Company promises to pay to the order of the Holder the principal amount first written above on July 3, 2026 (the “Maturity Date”), unless the Company and Holder mutually agree to extend the Maturity Date by two months (the “Extension Period”), in full in cash (subject to the conversion provisions hereof) or on such earlier 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 and otherwise to pay interest to the Holder on the aggregate unconverted and then outstanding principal amount of this Note and such other Obligations in accordance with the provisions hereof. Amounts repaid will not be advanced again.

This Note is subject to the following additional provisions:

Section 1. REPAYMENT

a) Repayment at Maturity. On the Maturity Date, the Company shall repay Holder all outstanding Obligations.

b) Mandatory Prepayments. On the next business day following any Company Party or any Subsidiary of any Company Party 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, pay to the Holder in cash the amount needed to repay all outstanding Obligations (a “Mandatory Prepayment Amount”). The Company shall provide notice to the Holder of the closing of such Subsequent Offering, including the expected net proceeds thereof, not later than the 10^th day preceding the date of consummation of such Subsequent Offering, which notice shall be irrevocable and constitute an agreement to pay the Mandatory Prepayment Amount on the date of consummation of such Subsequent Offering. The Holder may continue to convert the principal amounts to be prepaid under this Note until the date of consummation of such Subsequent Offering; provided, that, if the Company does not provide such notice, in addition to all other remedies provided under the Transaction Documents for failure to comply with this Note, the Holder may convert the Note in the amount of such payment and, in its sole discretion, either return such payment or apply such payment to other outstanding Obligations, if any. In the event that the terms of the Subsequent Offering do not provide for the repayment in cash in full of all outstanding Obligations, the Holder may choose, in its sole discretion, to adjust the Conversion Price to match the price of the Common Stock issued or implied by such Subsequent Offering. This ‎Section 1(‎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.

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, including any Obligation to deliver Securities), which shall accrue daily at the rate of ten percent (10%) 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 interest shall accrue daily at the rate of twelve percent (12%) per annum during any Extension Period. Accrued and unpaid interest shall be due and payable on the first day of each calendar month, on each Conversion Date and on the Maturity Date, and as otherwise set forth herein. Any interest accrued and unpaid on any 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. 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 Holder all of which are hereby waived, accrue and be owed daily at an increased interest rate equal to the lower of twenty-four percent (24%) per annum or the maximum rate permitted under applicable Regulations (the “Default Rate”). 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, including any Obligation to deliver any Security, that is not paid when due, in an amount equal to ten percent (10%) of such Obligation (which, in the case an Obligation to deliver a Security, shall be payable in Securities of the same type), 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 (other than any repayment required to be made by ‎Section 1(‎b) (Mandatory Prepayments), to the extent so required) that is made in cash at any time when (i) the Company shall not have received a notice from the Holder 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. 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 and the other 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 shall have the option to refuse or accept, in their sole discretion, any payment to the Holder or any other Purchaser Party attempted to be made without a required notice, without a required fee. The Holder 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 as a payment of 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 to the Holder or any other Purchaser Party, and any delivery of any Security under any Transaction Document to the Holder or any other Purchaser Party, received after 3 p.m. on any day shall be deemed received (i) on the next business day, in the case of any such payment and (ii) on the next trading day, in the case of any such delivery. Each determination by the Holder of an amount of interest or fee due hereunder shall be conclusive and binding for all purposes, absent manifest error.

Section 2. Conversion

a) Voluntary Conversion. At any time after the Original Issue Date, and subject to receiving the requisite shareholder approval pursuant to the Regulations of the Principal Trading Market as set forth in Section 2(e) (Exchange Cap) to allow for conversion of all or any portion of this Note, 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 2(‎d) (Beneficial Ownership Limitation) and ‎Section 2(‎1(a) (Exchange Cap)). The Holder shall effect conversions by delivering to the Company a conversion notice, the form of which is attached hereto as Annex A (each, a “Conversion Notice”), specifying therein the amount of such Obligations to be converted and the date on which such conversion must be effected (such date, the “Conversion Date”). If no Conversion Date is specified in a Conversion Notice, the Conversion Date shall be the date that such Conversion Notice is deemed delivered hereunder. The form Conversion Notice attached hereto as Annex A set forth the totality of the procedures required of the Holder in order to convert this Note. Without limiting the foregoing, no ink-original Conversion Notice shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Conversion Notice form be required in order to convert this Note. No additional document (including legal opinion), other information or instructions shall be required of the Holder to convert the Note. The Company shall honor conversions of the Note and shall deliver the Common Stock on the Conversion Date in accordance with the terms, conditions and time periods set forth in this Note and the other Transaction Documents. 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 in the form, and 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 Conversion Notice within one (1) business day of delivery of such Conversion Notice. 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. The conversion price in effect on any Conversion Date shall be equal to the lower of (i) $__________¹ and (ii) if the applicable Conversion Notice was delivered during the continuation of a Default or Event of Default, 95% of the lowest VWAP of the Common Stock during the period lasting five (5) consecutive trading days and ending on, and including, the trading day immediately preceding the date of such delivery (the “Conversion Price”). The price set forth in clause (i) of the definition of “Conversion Price” will be proportionately adjusted for any stock dividend, stock split, stock combination, reclassification or similar transaction that decreases or increases the number of shares of Common Stock issued to ensure that, in the case of the Conversion Price, the percentage of shares of Common Stock received by the Holder upon full conversion at the Conversion Price and, in each case, that the percentage of the value of the Company allocated to such Common Stock, both remain unchanged by any such transaction. Any reference herein to an adjustment of the Conversion Price shall mean an adjustment to such clauses. Upon such adjustment, the Conversion Price shall be rounded down to the nearest $0.01.

“VWAP” means, for or as of any date for any Security, the following:

(i) the dollar volume-weighted average price for such Security on the Principal Trading Market for such Security during the period beginning at 9:30:01 a.m., New York time, and ending at 4:00:00 p.m., New York time, as reported by Bloomberg through its “VWAP” function; or

(ii) if Bloomberg does not report such a price, the dollar volume-weighted average price of such Security in the over-the-counter market on the electronic bulletin board for such Security during the period beginning at 9:30:01 a.m., New York time, and ending at 4:00:00 p.m., New York time, as reported by Bloomberg; or

(iii) if no dollar volume-weighted average price is reported for such Security by Bloomberg for such hours, the average of the highest Closing Bid Price and the lowest Closing Sale Price of any of the market makers for such Security on such date as reported in the “pink sheets” by OTC Markets Group Inc. (formerly Pink Sheets LLC); or

(iv) if the VWAP cannot be calculated for such Security on such date on any of the foregoing bases, the VWAP of such Security on such date shall be the fair market value as mutually determined by the Company and the Holder.

¹ Should be equal to the Closing Sale Price of the Common Stock on the date stockholder approval is obtained.

“Closing Bid Price” and “Closing Sale Price” means, for any Security as of any date:

(i) the last closing bid price and last closing trade price, respectively, for such Security on the Principal

Trading Market for such Security, as reported by Bloomberg; or

(ii) if such Principal Trading Market begins to operate on an extended hours basis and does not designate the closing bid price or the closing trade price (as the case may be), then the last bid price or last trade price, respectively, of such Security prior to 4:00:00 p.m., New York time, as reported by Bloomberg; or

(iii) if such Security no longer trades on its Principal Trading Market, then the last closing bid price or last trade price, respectively, of such Security on the principal Trading Market where such Security is listed or traded as reported by Bloomberg; or

(iv) if such Security no longer trades on a Trading Market, the last closing bid price or last trade price, respectively, of such Security in the over-the-counter market on the electronic bulletin board for such Security as reported by Bloomberg; or

(v) if no closing bid price or last trade price, respectively, is reported for such Security by Bloomberg, the average of the bid prices, or the ask prices, respectively, of any market makers for such Security as reported in the “pink sheets” by OTC Markets Group Inc. (formerly Pink Sheets LLC); or

(vi) if the “Closing Bid Price” or the “Closing Sale Price” cannot be calculated for a Security on a particular date based on the foregoing, the “Closing Bid Price” and the “Closing Sale Price” of such Security on such date shall be the fair market value as mutually determined by the Company and the Holder; or

(vii) if the Company and the Holder are unable to agree upon the fair market value of such Security, then such dispute shall be resolved, and such fair market value (and therefore the “Closing Bid Price” and “Closing Sale Price”) shall be determined, in accordance with the procedures set forth in ‎Section 6(‎d).

All such determinations shall be appropriately adjusted for any stock splits, stock dividends, stock combinations, recapitalizations or other similar transactions during such period.

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 Obligations 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 Deadline”), 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 2(‎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 request by the Holder 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 at least equal the Reserve Amount for the sole purpose of issuance of Issuable Securities to the Holder under and as provided in the Transaction Documents, free from preemptive rights or any other actual contingent purchase rights of persons other than such Holder and such other holders. 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 Conversion Notice.

vi. Failure to Deliver Certificates. If, in the case of any Conversion Notice, such certificate or certificates are not delivered to or as directed by the applicable Holder by the Share Delivery Deadline, 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 Conversion Notice.

vii. Obligation Absolute. 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.

viii. Compensation For Late Delivery. If the Company fails for any reason to deliver to the Holder such certificate or certificates pursuant to ‎Section 2(‎c)(‎ii) by the Share Delivery Deadline, the Company shall pay to the Holder, in cash, as partial damages and not as a penalty, a late delivery fee (each a “Late Delivery Fee”) in an amount equal to $1,000 per trading day for each trading day after such Share Delivery Deadline until such certificates are delivered or Holder rescinds such conversion. Nothing herein shall limit a Holder’s right to pursue, in addition to and not in substitution for, actual damages or declare an Event of Default for the Company’s failure to deliver Conversion Shares within the period specified herein; and the Holder shall have the right to pursue all additional 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.

ix. Buy-In, Recission or Late Delivery. In addition to any other rights available to the Holder, if the Company fails for any reason to deliver to the Holder a number of shares of Common Stock (or a certificate thereof) by the deadline set forth in, and while strictly complying with, the terms of this Note and the other Transaction Documents, the Holder may choose, in its sole discretion, on or after such deadline, in addition to any other available remedy, to do any of the following (or any combination thereof), each of which will, if applicable, void any related Conversion Notice to the extent thereof: (A) cancel such conversion and retain the unconverted Obligations, (B) purchase, whether in an open market transaction or otherwise, whether directly or through a broker or other agent (a “Buy-In”), a number of shares of Common Stock not to exceed the number of shares subject to such delivery failure, and, within three (3) business days after receipt of such Holder’s request therefor and in such Holder’s discretion, the Company shall repay the Obligations that would, in the absence of such failure to deliver such shares of Common Stock, have been repaid by paying to the Holder in cash an amount equal to the Holder’s total gross purchase price (including brokerage commissions, fees and other costs, fees and expenses, if any) for such shares of Common Stock so purchased; (C) accept from the Company late delivery of shares of Common Stock after such deadline (provided, that such acceptance shall not waive any right of the Holder, to damages or otherwise, caused by such delay); or (D) require that the Company repay in cash all or some of the Obligations that would have been repaid in the absence of such failure to deliver such shares of Common Stock, in an amount equal to (x) the number of shares of Common Stock that would have been delivered to the Holder in the absence of such failure times (y) a price per share equal to the Closing Sale Price of Common Stock on such deadline (or if such deadline is not a trading day, the trading day immediately preceding such day); provided, that, in each case, the voiding of such Conversion Notice shall not affect the Company’s obligations to make any payments which have accrued prior to the date of such notice pursuant to the terms of this Note or the other Transaction Documents. 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 or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock on such deadline as required pursuant to the terms of this Note and the other Transaction Documents.

x. No Limitation on Damages. More generally, nothing in this ‎Section 2, 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 5 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 2 shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable Regulation.

d) Beneficial Ownership Limitation. Anything else in the Transaction Documents notwithstanding, the Company shall not at any time effect any conversion of principal or interest of this Note, and the Holder shall not have the right to convert at any time any principal or interest of this Note, to the extent, and only to the extent, that after giving effect to the conversion set forth on the applicable Conversion Notice, 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 (collectively, the “Attribution Parties”), would beneficially own Common Stock in excess of 9.99% of the number of shares of the Common Stock outstanding (as the same may be increased on decreased in accordance with this Section 2(d), the “Beneficial Ownership Limitation”); provided, that the Holder may, with prior notice to the Company, decrease such percentage and, if such percentage was previously decreased, the Holder may, upon not less than sixty-one (61) days’ prior notice to the Company and effective at the end of such 61-day period, increase such percentage up to, and in any case not exceeding, 9.99%. When calculating the Beneficial Ownership Limitation, 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 Purchased Securities and any other warrants and other convertible or exchangeable and similar Securities) and beneficially owned by the Holder or any of its Attribution Parties. No prior determination pursuant to this Section 2(d) shall have any effect on the applicability of the provisions of this Section 2(d) with respect to any subsequent determination. Except as set forth above, for purposes of this Section 2(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 2(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. For purposes of this Section 2(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 promptly (and in any event within one (1) trading day) confirm in writing to the Holder the number of shares of Common Stock then outstanding. Irrespective of such reliance, the Holder shall in its calculation give 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 provisions of this Section 2(d) shall not be strictly interpreted in accordance with its terms as maybe necessary to correct any portion of this Section 2(d) that may be defective or inconsistent with the intended beneficial ownership limitations contained herein as they relate to applicable Regulations of the SEC or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this Section 2(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 until the Company seeks shareholder approval for the issuance of shares of Common Stock underlying the Note pursuant to the Regulations of the Principal Trading Market for the Common Stock (the “Exchange Cap”), except that such limitation shall not apply in the event that the Company 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. In the event that the Holder sells or otherwise transfers any portion of this Note, the transferee shall be allocated a pro rata portion of the Holder’s Exchange Cap with respect to such portion of this Note so transferred. In the event that the Company is prohibited from issuing any shares of Common Stock pursuant to this ‎Section 2(‎(a) (the “Exchange Cap Shares”) to the Holder, the Company shall obtain shareholder approval to issue such Exchange Cap Shares within sixty (60) days of the Closing Date; provided, that the Holder may instead choose to exercise any of the options set forth in ‎Section 2(‎c)(‎ix) (Buy-In, Recission or Late Delivery).]

Section 3. Registration of Transfers and Exchanges

a) Different Denominations. This Note is exchangeable for new notes of different denominations having, in the aggregate, the same principal amount and otherwise the same terms, as may be requested by the Holder surrendering the same. No service charge or other amount 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. EVENTS REQUIRING Adjustments

a) Restricted Payments. 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).

b) Stock Dividends and Stock Splits. If the Company, at any time while any Obligation 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 shares held the Company or any of its Subsidiaries) outstanding immediately after such event, and of which the denominator shall be the number of shares of Common Stock outstanding immediately before such event. Any adjustment made pursuant to this ‎Section 4(‎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.

c) Change in Other Common Stock Equivalents. If the purchase or exercise price provided for in any Common Stock Equivalents, the additional consideration, if any, payable pursuant to any Common Stock Equivalents with respect to shares of Common Stock, or the rate at which Common Stock may be acquired pursuant to any Common Stock Equivalents changes at any time (other than any change to this Note or any other Purchased Securities), the Conversion Price in effect at the time of such increase or decrease shall be adjusted to account proportionately, for such change. For purposes of this ‎Section 4(‎c), if the terms of any Common Stock Equivalents are changed in the manner described in the immediately preceding sentence, then such Common Stock Equivalents and the shares of Common Stock deemed issuable thereunder shall be deemed to have been issued as of the date of such change. No adjustment pursuant to this ‎Section 4(‎c) shall be made to the Conversion Price if such adjustment would result in an increase to the Conversion Price then in effect.

d) Dilutive Issuances. 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 or is otherwise entitled to receive and has not yet received Common Stock under any Transaction Document, shall conduct a Subsequent Offering of Common Stock or otherwise offer, issue, Sell or offer or Sell any option to purchase, or sell or any right to reprice, any shares of Common Stock or any Common Stock Equivalents (or announce any such offer, Sale or issue), in each case other than as part of 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 lower of (i) the Base Share Price and (ii) the lowest VWAP of the Common Stock in the five (5) days immediately following such Dilutive Issuance. Such adjustment shall be made whenever such shares of Common Stock or Stock Equivalents are issued. For the avoidance of doubt, it is understood and agreed that (i) 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 and (ii) if such transaction shall be a Variable Rate Transaction, it shall be deemed to have been entered into at the lowest possible conversion or exercise price therefor. The Company shall notify the Holder, in writing, no later than the trading day following the public disclosure of the issuance or deemed issuance of any shares of Common Stock or Stock Equivalents subject to this ‎Section 4(‎d), indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price and other pricing terms (such notice, the “Dilutive Issuance Notice”). For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this ‎Section 4(‎d), 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 Conversion Notice.

e) 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 2(‎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 2(‎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 being 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 (either (x) if the Holder consents to receive, or to the extent possible without the Holder receiving, material non-public information, prior to the closing of such Fundamental Transaction or (y) otherwise, within thirty (30) calendar days after such closing) 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. If the Holder consents to receive material non-public information or, if and to the extent possible, without the Holder receiving material non-public information, 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 4 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 4, 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 4, the Company shall ensure that the event requiring such adjustment is publicly disclosed within the time required by applicable SEC Regulations (and, if no such Regulation applies, before the trading day next following such event) and, not later than one (1) trading day following such public disclosure, the Company shall 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. Notwithstanding anything in this ‎Section 4 to the contrary, no adjustment pursuant to this ‎Section 4 shall increase the Conversion Price other than proportional increases upon the occurrence of a reverse stock split in accordance with ‎Section 4(‎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, after the public disclosure thereof but in any event 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.
