DUE: April 18, 2018

FOR VALUE RECEIVED, the undersigned, MLIGHT TECH, INC. (herein called the “Company”), a Florida corporation, promises to pay to the order HE CEN, or his or its registered assigns (the “Holder” or “Holders”), the principal sum of one hundred and fifty thousand dollars (US$150,000), as such amount is reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise (the “Principal”), on April 18, 2018 (the “Maturity Date”), together with interest (computed on the basis of a 365-day year) on the outstanding principal amount at the rate of eight percent (8%) per annum (the “Interest Rate”) from the date hereof, payable on June 30, 2017 and, thereafter, quarterly in arrears, until the principal hereof shall have become due and payable.

1. Securities Purchase Agreement. This Debenture has been issued pursuant to the terms and conditions set forth in the Securities Purchase Agreement dated as of April 19, 2017 by and among the Company and, inter alia, the Holder, (as from time to time amended, the “Securities Purchase Agreement”). All of the terms and conditions of such Securities Purchase Agreement are incorporated herein by this reference, and all capitalized terms not separately defined in this Debenture, shall have the same meanings as defined in the Securities Purchase Agreement.

2. Debenture. Payments of principal of, and interest on, this Debenture are to be made in lawful money of the United States of America at such place as provided in the Securities Purchase Agreement. This Debenture is the 8% Series A Convertible Debenture (herein called the “Debenture”) issued pursuant to the Securities Purchase Agreement, and is subject to other terms as set forth in the Securities Purchase Agreement.

3. Interest. Interest on this Debenture shall commence accruing on the Issuance Date, shall accrue daily at the Interest Rate on the outstanding Principal amount from time to time, shall be computed on the basis of a 365-day year comprised of twelve (12) months and shall be payable in arrears upon the earlier of (i) the last day of June, September, December and March, commencing on the Issuance Date, until the principal hereof shall have become due and payable and, (ii) the date of conversion into Common Stock in accordance with Section 5 herein below.

4. Prepayment. At any time after the Issuance Date prior to the Maturity Date, Company shall have the right to prepay this Debenture in full or any portion of the then outstanding principal balance prior to the Maturity Date, provided that the Company give written notice to the Purchasers at least ten (10) business days before the prepayment and; provided further that Purchasers may during five (5) business days of receipt of such notice elect to convert the Debentures in accordance with their terms set forth herein, although such conversion shall not be effective until sixty-one (61) days following the date of Purchasers’ notice of election.

5. Conversion into Common Stock

a. General.

(i)  Conversion into Common Stock. Subject to the provisions of Section 5(a)(iii) and 5(e), on any one or more occasions on or after the date hereof, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into fully paid and non-assessable shares of common stock of the Company, par value $0.0001 per share (the “Common Stock”), or any shares of capital stock or other securities of the Company into which such Common Stock shall hereafter be changed, exchanged or reclassified in accordance with Section 5(c), at the Conversion Rate (as defined below) then in effect. The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up to the nearest whole share. The Company shall pay any and all transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery of Common Stock upon conversion of any Conversion Amount. Any such conversion set forth in a conversion notice dated prior thereto, shall be deemed to be effective as of the date of such conversion notice (the “Conversion Date”).

(ii) Conversion Rate. The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to Section 5(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”). The Conversion Amount shall be subject from time to time to adjustment as described below.

1. “Conversion Amount” means the sum of (A) the portion of the Principal to be converted, amortized, redeemed or otherwise with respect to which this determination is being made, and (B) any accrued and unpaid Interest.

2. “Conversion Price” means, as of any Conversion Date (as defined below) or other date of determination, $0.01 per share, subject to adjustment as provided herein.

(iii) Conversion Limit. Notwithstanding anything to the contrary set forth in this Debenture, at no time may a Holder of this Debenture convert this Debenture into Common Stock if the number of shares of Common Stock to be issued pursuant to such conversion would cause the number of shares of Common Stock owned by such Holder at such time to exceed, when aggregated with all other shares of Common Stock owned by such Holder and its affiliates at such time, the number of shares of Common Stock which would result in such Holder, its affiliates, any investment manager having discretionary investment authority over the accounts or assets of such Holder, or any other persons whose beneficial ownership of Common Stock would be aggregated with such Holder’s for purposes of Section 13(d) and Section 16 of the 1934 Act, beneficially owning (as determined in accordance with Section 13(d) of the 1934 Act and the rules thereunder) in excess of 9.99% of the then issued and outstanding shares of Common Stock (the "Holder Cap").

(iv) Effect of Conversion. Upon conversion of this Debenture in full in the manner provided by this Section 5 (c) below, this Debenture shall be deemed fully satisfied and cancelled.

b. Authorized Shares. The Company covenants that during the period the conversion right exists, the Company will reserve from its authorized and unissued Common Stock, free from preemptive rights, to provide for the issuance of 110% of the number of shares of Common Stock upon the full conversion of the Holder’s Debenture and the other Debentures issued pursuant to the Securities Purchase Agreement (the “Reserved Amount”). If the Company shall issue any securities or make any change to its capital structure which would change the number of shares of Common Stock into which the Debentures shall be convertible at the then current Conversion Price, the Company shall at the same time make proper provision so that thereafter there shall be a sufficient number of shares of Common Stock authorized and reserved, free from preemptive rights, for conversion of the outstanding Debentures. The Company (i) acknowledges that it has irrevocably authorized by its Board of Directors to issue certificates for the Common Stock issuable upon conversion of the Holder’s Debenture, and (ii) agrees that its issuance of the Holder’s Debenture shall constitute full authority to its officers and agents who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for shares of Common Stock in accordance with the terms and conditions of the Holder’s Debenture.

c. Method of Conversion.

(i) Mechanics of Conversion. Subject to Section 5(a), the Holder’s Debenture may be converted by the Holder in whole or in part, by (i) submitting to the Company a conversion notice (by facsimile or other reasonable means of communication dispatched on the Conversion Date prior to 6:00 p.m., New York, New York time) and (ii) subject to Section 5(c)(ii), surrendering the Holder’s Debenture at the principal office of the Company.

(ii) Surrender of Debenture upon Conversion. Notwithstanding anything to the contrary set forth herein, upon conversion of the Holder’s Debenture in accordance with the terms hereof, the Holder shall not be required to physically surrender the Holder’s Debenture to the Company unless the entire unpaid principal amount of the Holder’s Debenture is so converted. The Holder and the Company shall maintain records showing the principal amount so converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of the Holder’s Debenture upon each such conversion. In the event of any dispute or discrepancy, such records of the Company shall be controlling and determinative in the absence of manifest error. Notwithstanding the foregoing, if any portion of the Holder’s Debenture is converted as aforesaid, the Holder may not transfer the Holder’s Debenture unless the Holder first physically surrenders the Holder’s Debenture to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Debenture of like tenor, registered as the Holder (upon payment by the Holder of any applicable transfer taxes) may request, representing in the aggregate the remaining unpaid principal amount of the Holder’s Debenture. The Holder and any assignee, by acceptance of the Holder’s Debenture, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of a portion of the Holder’s Debenture, the unpaid and unconverted principal amount of the Holder’s Debenture represented by the Holder’s Debenture may be less than the amount stated on the face hereof.

(iii) Delivery of Common Stock upon Conversion. Upon receipt by the Company from the Holder of a facsimile transmission (or other reasonable means of communication) of a conversion notice meeting the requirements for conversion as provided in this Section 5(c), the Company shall issue and deliver or cause to be issued and delivered to or upon the order of the Holder certificates for the Common Stock issuable upon such conversion within three (3) Business Days (such third Business Day being hereinafter referred to as the “Deadline”) in accordance with the terms hereof and the Securities Purchase Agreement.

(iv) Obligation of Company to Deliver Common Stock. Upon delivery by the Holder to the Company of a Conversion notice, the Holder shall be deemed to be the Holder of record of the Common Stock issuable upon such conversion, the outstanding principal amount and the amount of accrued and unpaid interest on that portion of the Holder’s Debenture being converted shall be reduced to reflect such conversion, and, unless the Company defaults on its obligations under this Section 5, all rights with respect to the portion of the Holder’s Debenture being so converted shall forthwith terminate except the right to receive the Common Stock or other securities, cash or other assets, as herein provided, on such conversion. If the Holder shall have given a conversion notice as provided herein, the Company’s obligation to issue and deliver the certificates for Common Stock shall be absolute and unconditional, irrespective of the absence of any action by the Holder to enforce the same, any waiver or consent with respect to any provision thereof, the recovery of any judgment against any Person or any action to enforce the same, any failure or delay in the enforcement of any other obligation of the Company to the Holder of record, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder of any obligation to the Company, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with such conversion. The Conversion Date specified in the conversion notice shall be the Conversion Date so long as the conversion notice is received by the Company before 6:00 p.m., New York, New York time, on such date.

(vi) Pro Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one holder of Debentures for the same Conversion Date and the Company can convert some, but not all, of such portions of the Debentures submitted for conversion, the Company, subject to Section 5(a)(iii), shall convert from each holder of Debentures electing to have Debentures converted on such date a pro rata amount of such holder’s portion of its Debentures submitted for conversion based on the principal amount of Debentures submitted for conversion on such date by such holder relative to the aggregate principal amount of all Debentures submitted for conversion on such date. In the event of a dispute as to the number of shares of Common Stock issuable to the Holder in connection with a conversion of this Debenture, the Company shall issue to the Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 19.

d. Certain Adjustments.

(i) Subdivision or Combination of Common Stock. If the Company at any time subdivides (by any stock split, stock dividend, recapitalization, reorganization, reclassification or otherwise) the shares of Common Stock acquirable hereunder into a greater number of shares, then, after the date of record for effecting such subdivision, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. If the Company at any time combines (by any reverse stock split, recapitalization, reorganization, reclassification or otherwise) the shares of Common Stock acquirable hereunder into a smaller number of shares, then, after the date of record for effecting such combination, the Conversion Price in effect immediately prior to such combination will be proportionately increased.

(ii) Reclassification, Exchange, and Substitution.  If at any time or from time to time after the date upon which this Debenture was issued by the Company (the “ Original Issue Date”), the shares of Common Stock issuable upon the conversion of this Debenture shall be changed into the same or a different number of shares of any class or classes of stock, whether by recapitalization, reclassification, reorganization, merger, exchange, consolidation, sale of assets or otherwise, then, in any such event, each holder of the Debentures shall have the right thereafter to convert such stock into the kind and amount of stock and other securities and property receivable upon such recapitalization, reclassification, reorganization, merger, exchange, consolidation, sale of assets, distribution of assets or other change by a holder of the number of shares of Common Stock into which such shares of this Debenture could have been converted immediately prior to such recapitalization, reclassification, reorganization, merger, exchange, consolidation, sale of assets, distribution of assets or other change, or with respect to such other securities or property by the terms thereof.

(iii) 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 treasury shares, if any) issued and outstanding.

(iv) Notice of Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price as a result of the events described in this Section 5(d), the Company, at its expense, shall promptly compute such adjustment or readjustment and prepare and furnish to the Holder of this Debenture a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. Failure to give such notice or any defect therein shall not effect the legality or validity of the subject adjustment.

e. Intentionally Left Blank.

f. Concerning the Shares.

(i) Legend. The shares of Common Stock issuable upon conversion of the Debenture may not be sold or transferred unless (A) such shares are sold pursuant to an effective registration statement under the Securities Act, or (B) the Company or its transfer agent shall have been furnished with an opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions and from an attorney that regularly practices securities law) to the effect that the shares to be sold or transferred may be sold or transferred pursuant to an exemption from such registration, or (C) such shares are sold or transferred pursuant to Rule 144 under the Securities Act (or a successor rule) (“Rule 144”), or (D) such shares are sold or transferred outside the United States in accordance with Rule 904 of Regulation S under the Securities Act, or (E) such shares are transferred to an “affiliate” (as defined in Rule 144) of the Company who agrees to sell or otherwise transfer the shares only in accordance with this Section 5(e). Except as otherwise provided in this Agreement (and subject to the removal provisions set forth below), until such time as the shares of Common Stock issuable upon conversion of the Debenture have been registered under the Securities Act as contemplated by the Registration Rights Agreement, otherwise may be sold pursuant to Rule 144 without any restriction as to the number of securities as of a particular date that can then be immediately sold, each certificate for shares of Common Stock issuable upon conversion of the Debenture that has not been so included in an effective registration statement or that has not been sold pursuant to an effective registration statement or an exemption that permits removal of the legend, shall bear a legend substantially in the following form, as appropriate:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”). THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A) TO THE CORPORATION, (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT, (C) WITHIN THE UNITED STATES AFTER REGISTRATION OR IN ACCORDANCE WITH THE EXEMPTION FROM THE REGISTRATION REQUIREMENTS UNDER THE U.S. SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF APPLICABLE, AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS, OR (D) WITHIN THE UNITED STATES IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS AND THE HOLDER HAS PRIOR TO SUCH SALE FURNISHED TO THE CORPORATION AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE CORPORATION.

(ii) Removal of Legend. The legend set forth above shall be removed and the Company shall issue to the Holder a new certificate therefor free of any transfer legend if (A) the Company or its transfer agent shall have received an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable transactions, to the effect that a public sale or transfer of such Common Stock may be made without registration under the Act and the shares are so sold or transferred, or (B) in the case of the Common Stock issuable upon conversion of the Holder’s Debenture, such security is registered for sale by the Holder under an effective registration statement filed under the Securities Act or otherwise may be sold pursuant to Rule 144 without any restriction as to the number of securities as of a particular date that can then be immediately sold. The Company shall cause its counsel to issue a legal opinion to the Company’s transfer agent promptly after the effective date of any registration statement under the Securities Act registering the resale of the Common Stock issuable upon conversion of the Debenture if required by the Company’s transfer agent to effect the removal of the legend hereunder. Nothing in the Debenture shall (x) limit the Company’s obligation under the Registration Rights Agreement or (y) affect in any way the Holder’s obligations to comply with applicable prospectus delivery requirements upon the resale of the securities referred to herein.

(g) Distribution of Assets; If the Company shall declare or make any dividend or other distributions of its assets (or rights to acquire its assets) to any or all holders of shares of Common Stock, by way of return of capital or otherwise (including without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (the “Distributions”), then the Holder will be entitled to such Distributions as if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Debenture (without taking into account any limitations or restrictions on the convertibility of this Debenture) immediately prior to the date on which a record is taken for such Distribution or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for such Distributions (provided, however, to the extent that the Holder’s right to participate in any such Distributions would result in the Company exceeding the Exchange Cap, then the Holder shall not be entitled to participate in such Distribution to such extent (or the beneficial ownership of any such shares of Common Stock as a result of such Distribution to such extent) and such Distribution to such extent 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 Company exceeding the Exchange Cap).

6. Status as Shareholder. Upon submission of a conversion notice by the Holder of this Debenture, (i) the shares covered thereby (other than the shares, if any, which cannot be issued because their issuance would exceed such Holder’s allocated portion of the Reserved Amount or cause the Company to exceed the Exchange Cap) shall be deemed converted into shares of Common Stock and (ii) the Holder’s rights as a Holder of such converted portion of the Holder’s Debenture shall cease and terminate, excepting only the right to receive certificates for such shares of Common Stock and to any remedies provided herein or otherwise available at law or in equity to such Holder because of a failure by the Company to comply with the terms of the Holder’s Debenture. Notwithstanding the foregoing, if a Holder has not received certificates for all shares of Common Stock prior to the third (3^rd) Business Day after the Deadline, Holder may elect at such Holder’s option to regain the rights of a Holder of the Holder’s Debenture with respect to such attempted converted portions of the Holder’s Debenture and the Company shall, as soon as practicable, return such attempted converted Debenture to the Holder or, if the Debenture has not been surrendered, adjust its records to reflect that such portion of the Holder’s Debenture has not been converted. In all cases, the Holder shall retain all of its rights and remedies for the Company’s failure to convert the Holder’s Debenture.

7. Governing Law; Consent to Jurisdiction; Waiver of Jury Trial.

a. This Debenture shall be governed by, and construed in accordance with, the internal laws of the State of New York without regard to the choice of law principles thereof.

Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS DEBENTURE AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

b. Each party shall bear its own expenses in any litigation conducted under this section.

c. At any time following the tenth (10^th) consecutive Business Day that the Reserved Amount is less than the number of shares of Common Stock that the Holder would be entitled to receive upon a conversion of the full Conversion Amount of this Debenture (without regard to any limitations on conversion set forth in Section 5(a)(iii) or otherwise and except as limited by Section 5(e)).

d. The Company defaults in the performance of or compliance with its obligations under any of this Debenture, the Securities Purchase Agreement or any of the Transaction Documents and such default has not been cured for thirty (30) days after written notice of default is given to the Company; or

f. The Company (i) admits in writing its inability to pay, its debts as they become due, (ii) files, or consents by answer or otherwise to the filing against it of a petition for relief or reorganization or arrangement or any other petition in bankruptcy, for liquidation or to take advantage of any bankruptcy, insolvency, reorganization, moratorium or other similar law of any jurisdiction, (iii) makes an assignment for the benefit of its creditors, (iv) consents to the appointment of a custodian, receiver, trustee or other officer with similar powers with respect to it or with respect to any substantial part of its property, (v) is adjudicated as insolvent or to be liquidated, or (vi) takes corporate action for the purpose of any of the foregoing; or

11. Vote To Issue, Or Change The Terms Of, Debentures. The written consent of the Holders of at least 51% of the holders of the then outstanding Debentures shall be required for any change, modification or amendment to any of the Debentures, unless the change shall only effect the Holder and the Company shall have offered such change to all holders of Debentures, in which case only the consent of the Holder is required.

All amounts denominated in other currencies shall be converted in the U.S. dollar equivalent amount in accordance with the Exchange Rate on the date of calculation. “Exchange Rate” means, in relation to any amount of currency to be converted into U.S. dollars pursuant to this Debenture, the U.S. dollar exchange rate as published in the Wall Street Journal on the relevant date of calculation (it being understood and agreed that where an amount is calculated with reference to, or over, a period of time, the date of calculation shall be the final date of such period of time).

If any provision of this Debenture is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Debenture so long as this Debenture as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).
