b) Interest Calculations. Interest shall be calculated on the basis of a 360-day year, consisting of twelve 30 calendar day periods, and shall accrue daily commencing on the Original Issue Date until payment in full of the outstanding principal amount, together with all accrued and unpaid interest, liquidated damages and other amounts which may become due hereunder, has been made. Interest shall cease to accrue with respect to any principal amount converted, provided that, the Company actually delivers the Conversion Shares within the time period required by Section 4(d)(ii) herein.

Section 4. Conversion.

a) Conversion. In the event that the Company consummates an IPO, then the total outstanding principal amount of this Note and any unpaid accrued interest thereon shall automatically convert into Conversion Shares, without any further action by the Holder a “Conversion”). The applicable date of conversion, with respect to a Conversion (the “Conversion Date”) shall be the date of the closing of the IPO. The Company shall deliver to the Holder written notice of the Conversion, including the material terms thereof and a calculation of the Conversion Price with supporting detail, at least twenty (20) days prior to the proposed Conversion Date. Upon a Conversion hereunder, the Holder shall surrender this Note as promptly as is reasonably practicable after the Conversion Date without delaying the Company’s obligation to deliver the shares on the Share Delivery Date.

b) Conversion Price. The conversion price applicable to a Conversion shall be equal to 70% of the initial public offering price of the Company’s Securities in the IPO, subject to any adjustments provided in this Note (the “Conversion Price”).

c) Mechanics of Conversion.

i. Conversion Shares Issuable upon Conversion of Principal Amount and Interest. The number of Conversion Shares issuable upon a Conversion hereunder shall be determined by the quotient obtained by dividing (x) the outstanding principal amount of this Note and accrued and unpaid interest to be converted by (y) the Conversion Price.

ii. Delivery of Conversion Shares Upon Conversion. Not later than five (5) Business Days after the Conversion Date (the “Share Delivery Date”), the Company shall deliver, or cause to be delivered, to the Holder a notice of issuance for the number of Conversion Shares being acquired upon the Conversion of this Note, which shall include the restrictive legends described below, unless it is otherwise determined in good faith that such restrictive legends are not required.

iii. Reservation of Shares Issuable Upon Conversion. The Company covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock 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, not less than such aggregate number of shares of the Common Stock as shall (subject to the terms and conditions set forth in the Purchase Agreement) be issuable (taking into account the adjustments and restrictions of Section 5) upon the Conversion of the then outstanding principal amount of this Note and payment of interest hereunder. 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.

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 Conversion Shares 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 Conversion Shares, 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 Conversion Shares 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 Conversion Shares 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.

Section 5. Certain Adjustments.

a) Stock Dividends and Stock Splits. If the Company, at any time while this Note is outstanding: (A) pays a stock dividend or otherwise makes a distribution or distributions on shares of its Common Stock or any Common Stock Equivalent (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Note), (B) subdivides outstanding shares of Common Stock into a larger number of shares, (C) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (D) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then, in each such case, the Company shall make an applicable adjustment to the Conversion Price to equitably increase or reduce the number of shares issuable upon the Conversion of this Note, as determined by its Board of Directors. Any adjustment made pursuant to this Section 5(a) shall become effective (x) immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, (y) immediately after the effective date in the case of a subdivision, combination or re-classification, or (z) as determined in the good faith reasonable judgment of the Board of Directors in any other case taking into account any recommendation including in any opinion received in connection with an adjustment.

b) 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.

c) Notice to the Holder. Whenever the Conversion Price is adjusted pursuant to any provision of this Section 5, the Company shall deliver to each Holder within two (2) Business Days a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

Section 6. Events of Default.

a) “Event of Default” means, wherever used herein, any of the following events (whatever the reason for such event and whether such event shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court, or any order, rule or regulation of any administrative or governmental body):

i. any default in the payment of (A) the principal amount of this Note or (B) interest, liquidated damages and other amounts owing to the Holder on this Note, as and when the same shall become due and payable (upon demand for payment by the Holder or by acceleration or otherwise) which default, solely in the case of an interest payment or other default under clause (B) above, is not cured within three (3) Business Days;

ii. the Company shall fail to observe or perform any other covenant or agreement contained in this Note or in any other Transaction Document, which failure is not cured, if possible to cure, within five (5) Business Days after notice of such failure sent by the Holder to the Company;

iii. any representation or warranty made in this Note or the Purchase Agreement, any written statement pursuant hereto or thereto or any other report, financial statement or certificate made or delivered to the Holder shall be untrue or incorrect in any material respect as of the date when made or deemed made;

iv. the Company or any Significant Subsidiary (as such term is defined in Rule 1-02(w) of Regulation S-X) shall be subject to a Bankruptcy Event; or

v. the Company shall fail to maintain a sufficient number of shares of Common Stock reserved for issuance upon the Conversion of this Note and such failure is not cured within thirty (30) days after written notice from the Holder.

b) Remedies Upon Event of Default. If any Event of Default occurs, subject to the Subordination Agreement, the outstanding principal amount of this Note, plus accrued but unpaid interest, liquidated damages and other amounts owing in respect thereof through the date of acceleration, shall become, at the Holder’s election, immediately due and payable, at the Holder’s election in cash. Upon the payment of this Note in full, including interest, the Holder shall promptly surrender this Note to or as directed by the Company. In connection with such acceleration described herein, the Holder need not provide, and the Company hereby waives, any presentment, demand, protest or other notice of any kind, and the Holder may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such acceleration may be rescinded and annulled by Holder at any time prior to payment hereunder and the Holder shall have all rights as a holder of the Note until such time, if any, as the Holder receives full payment pursuant to this Section 6(b). No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon. The Company shall pay the Holder hereof costs of collection, including reasonable attorneys’ fees.

Section 7. Miscellaneous.

a) Notices. Any and all notices or other communications or deliveries to be provided by the Holder or the Company hereunder shall be in writing and delivered as provided in Section 5.4 of 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, and accrued interest, as applicable, on this Note at the time, place, and rate, and in the coin or currency, herein prescribed. This Note is a direct debt obligation of the Company.

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 amount of this Note so mutilated, lost, stolen or destroyed, but only upon receipt of evidence of such loss, theft or destruction of such Note, and of the ownership hereof, reasonably satisfactory to the Company.

d) Governing Law; Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Note shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflict of laws thereof. Each party agrees that all legal proceedings concerning the interpretation, enforcement and defense of the transactions contemplated by this Note (whether brought against a party hereto or its respective Affiliates, directors, officers, shareholders, employees or agents) shall be commenced in the state and federal courts sitting in the City of New York, Borough of Manhattan (the “New York Courts”). Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of this Note, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of such New York Courts, or such New York Courts are improper or inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Note and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by applicable law. Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Note or the transactions contemplated hereby.

e) Waiver. Any waiver by the Company or the Holder of a breach of any provision of this Note shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Note. The failure of the Company or the Holder to insist upon strict adherence to any term of this Note on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Note on any other occasion. Any waiver by the Company or the Holder must be in writing.

f) Severability. If any provision of this Note is invalid, illegal or unenforceable, the balance of this Note shall remain in effect, and if any provision is inapplicable to any Person or circumstance, it shall nevertheless remain applicable to all other Persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder violates the applicable law governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum rate of interest permitted under applicable law. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of or interest on this Note as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Note, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefits or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Holder, but will suffer and permit the execution of every such as though no such law has been enacted.

g) Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the Holder’s right to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Note. 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). The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all other available remedies, to an injunction restraining any such breach or any such threatened breach, without the necessity of showing economic loss and without any bond or other security being required. The Company shall provide all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the Company’s compliance with the terms and conditions of this Note.

h) Next Business Day. Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day.

i) Headings. The headings contained herein are for convenience only, do not constitute a part of this Note and shall not be deemed to limit or affect any of the provisions hereof.

j) Amendments. This Note may be amended, in writing, by the mutual agreement of the Company and the Holder.

k) Expenses. The Company and the Holder will each bear their own legal and other expenses in connection with the preparation and negotiation of this Note. The Company shall pay all out-of-pocket expenses incurred by the Holder, including the fees, charges and disbursements of counsel for the Holder, in connection with the enforcement or protection of its rights (i) in connection with this Note, including its rights under this Section 7 and (ii) in connection with this Note, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of this Note (collectively, the “Enforcement Costs”).
