SECURED CONVERTIBLE DEBENTURE

Issue Amount: $3,600,000 New York, New York

January 24, 2008

FOR VALUE RECEIVED, the undersigned, Converted Organics, Inc., a Delaware corporation (referred to herein as the “Borrower”), with offices at 7A Commercial Wharf West, Boston, Massachusetts 02110, hereby unconditionally promises to pay to the order of PROFESSIONAL OFFSHORE OPPORTUNITY FUND, LTD., its endorsees, successors and/or assigns (the “Lender”), in lawful money of the United States, at 1400 Old Country Road, Suite 206, Westbury, New York 11590, or such other address as the Lender may from time to time designate, the principal sum of three million six hundred thousand Dollars ($3,600,000) (the “Issue Amount”). This Debenture shall mature and become due and payable in full on January 24, 2009 (the “Maturity Date”).

1. Original Issue Discount. The Lender shall purchase this Debenture at a price equal to 90% of the Issue Amount which shall represent a 10% Original Issue Discount.

2. Terms of Repayment. Principal of and interest on this Debenture shall be paid by the Borrower as follows:

(a) Interest at the rate of ten percent (10%) per annum from the date hereof through the Maturity Date shall be paid monthly by the Borrower in cash or, at the sole option of the Borrower, in registered shares of common stock at the average closing bid price of the common stock for the five (5) trading days immediately preceding the payment date.

(b) Principal shall be due and payable in full on the Maturity Date and shall be paid in cash.

(c) The Borrower further agrees that, if any payment made by the Borrower or any other person is applied to this Debenture and is at any time annulled, set aside, rescinded, invalidated, declared to be fraudulent or preferential or otherwise required to be refunded or repaid, or the proceeds of any property hereafter pledged as security for this Debenture is required to be returned by Lender to the Borrower, its estate, trustee, receiver or any other party, including, without limitation, under any bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of such payment or repayment, the Borrower’s liability hereunder (and any lien, security interest or other collateral securing such liability) shall be and remain in full force and effect, as fully as if such payment had never been made, or, if prior thereto any such lien, security interest or other collateral hereunder securing the Borrower’s liability hereunder shall have been released or terminated by virtue of such cancellation or surrender, this Debenture (and such lien, security interest or other collateral) shall be reinstated in full force and effect, and such prior cancellation or surrender shall not diminish, release, discharge, impair or otherwise affect the obligations of the Borrower in respect to the amount of such payment (or any lien, security interest or other collateral securing such obligation).

(d) All computations of interest shall be made by Lender on the basis of a year of 360 days for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable. Whenever any payment to be made hereunder shall be stated to be due on a day which is not a business day, such payment shall be made on the next succeeding day and such extension of time shall in such case be included in the computation of payment of interest.

(e) The Borrower may prepay all or any part of the outstanding principal amount of this Debenture, together with interest accrued, if any, excluding the interest that was prepaid as described in Section 1 (a) above on the amount prepaid through the date of prepayment, plus a premium, upon not fewer than ten (10) trading days’ prior written notice to the Lender. In the event such prepayment occurs prior to a registration statement has been declared effective for the Lender’s interest shares, warrants and common stock issuable on conversion of the Debentures, the amount paid shall be 125% of the principal deemed prepaid.

3. Conversion.

(a) The Lender shall have the option, at any time on or before the Maturity Date, to convert the outstanding principal of this Debenture into fully-paid and nonassessable shares of Borrower’s Common Stock at the rate per share equal to the lowest of (i) the Fixed Conversion Price, (ii) the Lowest Fixed Conversion Price or (iii) the Default Conversion Price (the “Conversion Rate”). As used herein, the following terms have the following meanings:

(i) Fixed Conversion Price means $6.00 per share.

(ii) Lowest Fixed Conversion Price means the lowest price, conversion price or exercise price set by the Borrower in any equity financing transaction, convertible security, or derivative instrument issued after the date hereof in a “New Transaction.” The term “New Transaction” as used in this Debenture and in any other Transaction Document, means any financing transaction consummated directly or indirectly by the Borrower with parties other than the Lender involving issuance of Common Stock or other securities convertible into or exercisable for Common Stock; provided, however, that the following share issuances shall not be deemed a New Transaction: (i) issuances pursuant to Employee Stock Ownership Plans; (ii) transactions with strategic industry or operating partners of the Borrower involving the issuance of Common Stock or securities convertible into Common Stock, or upon the exercise of warrants related to the deal terms of the foregoing; or (iii) issuance of stock options or warrants to employees, officers, or directors pursuant to compensation arrangements approved by the Borrower’s Board of Directors.

(iii) The Default Conversion Price means (if and so long as there exists an Event of Default hereunder) 70% of the average of the three lowest closing prices of the Common Stock during the twenty (20) day trading period immediately prior to a notice of conversion.

(b) If, but only if, a registration statement under the Securities Act of 1933, as amended, is effective covering sales of the Common Stock issuable upon exercise of this Debenture or if Lender may sell the shares issuable upon exercise of this Debenture pursuant to Rule 144 of the rules and regulations promulgated under the Securities Act of 1933, as amended (“Rule 144”), then the Borrower may require the Lender to convert the remaining principal amount outstanding if: (i) the Fair Market Value of the Common Stock for at least the immediately preceding ten consecutive trading days prior to delivery of a Borrower Conversion Notice (defined below) is at least 150% of the Conversion Rate in effect on the date of such Notice; and (ii) the average volume during such ten (10) day period is at least 100,000 shares per day, then the Company may send a notice (the “Borrower Conversion Notice”) to the Lender requiring them to convert any portion of their notes that remain outstanding at that time.

In the event such registration statement for any reason, whether by stop order, lapse of time or other event, becomes ineffective or otherwise unavailable for the sale of the Common Stock issuable upon conversion of this Debenture at any time within ninety (90) days after such conversion unless Lender can sell the shares issuable upon conversion of this Debenture pursuant to Rule 144, the Lender may deem the conversion null and void and the Borrower shall, upon request of the Lender and receipt of any stock certificates held by the Lender evidencing shares issued upon such conversion, reissue this Debenture for the remaining principal amount and pay any principal that would have been payable during such period, all as if such conversion had not occurred.

To exercise any conversion, the holder of this Debenture, either upon its own election or following receipt of the Borrower Conversion Notice, shall surrender the original Debenture to the Borrower during usual business hours at the offices of the Borrower, accompanied by a written notice in the form attached hereto as Exhibit A, Notice of Conversion, and made a part hereof.

(c) As promptly as practicable after the surrender of this Debenture by the Lender, the Borrower shall deliver or cause to be delivered to the Lender, certificates for the full number of Shares issuable upon conversion of this Debenture, in accordance with the provisions hereof, together with a duly executed new Debenture of the Borrower in the form of this Debenture for any principal amount not so converted. Such conversion shall be deemed to have been made at the time that this Debenture was surrendered for conversion and the notice specified herein shall have been received by the Borrower. If, however, the Borrower fails to deliver the full number of shares due upon any conversion within five (5) days following the demand of conversion, the Borrower shall pay liquidated damages in cash equal to $1,500 per day for each day the Shares are not delivered to the Lender.

(d) The number of shares issuable upon conversion of this Debenture or repayment by the Borrower in shares shall be proportionately adjusted if the Borrower shall declare a dividend of capital stock on its capital stock, or subdivide its outstanding capital stock into a larger number of shares by reclassification, stock split or otherwise, which adjustment shall be made effective immediately after the record date in the case of a dividend, and immediately after the effective date in the case of a subdivision. The number of shares issuable upon conversion of this Debenture or any part thereof shall be proportionately adjusted in the amount of securities for which the shares have been changed or exchanged in another transaction for other stock or securities, cash and/or any other property pursuant to a merger, consolidation or other combination. The Borrower shall promptly provide the holder of this Debenture with notice of any events mandating an adjustment to the conversion ratio, or for any planned merger, consolidation, share exchange or sale of the Borrower, signed by the President and Chief Executive Officer of Borrower.

(e) Percentage Cap. Notwithstanding the provisions of this Debenture, in no event (except (i) as specifically provided in the Debenture as an exception to this provision, (ii) during the forty-five (45) day period prior to the Maturity Date, or (iii) while there is outstanding a tender offer for any or all of the shares of the Borrower’s Common Stock) shall the Lender be entitled to convert this Debenture, or the Borrower have the obligation or option to issue shares upon such conversion or in lieu of cash payments hereunder, to the extent that, after such conversion or issuance the sum of (1) the number of shares of Common Stock beneficially owned by the Lender and its affiliates, and (2) the number of shares of Common Stock issuable upon the conversion of the Debenture with respect to which the determination of the proviso is being made, would result in beneficial ownership by the Lender and its affiliates of more than 4.99% (the “Percentage Cap”) of the outstanding shares of Common Stock (after taking into account the shares to be issued to the Lender upon such conversion). For purposes of the proviso to the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 12(d) of the Securities Exchange Act of 1934, as amended.

(f) Issuance Limitations. Notwithstanding anything to the contrary herein, unless Shareholder Approval (as defined in the Loan and Securities Agreement) has been obtained and deemed effective, the Company shall not make any issuance whatsoever of Common Stock issuable upon conversion of this Debenture if such issuance together with any issuances pursuant to the Warrant (as defined in the Loan and Securities Purchase Agreement) would require the Company to issue, in the aggregate more than 19.99% of its issued and outstanding Common Stock on the Closing Date.

4. Liability of the Borrower. The Borrower is unconditionally, and without regard to the liability of any other person, liable for the payment and performance of this Debenture and such liability shall not be affected by an extension of time, renewal, waiver, or modification of this Debenture or the release, substitution, or addition of collateral for this Debenture. Each person signing this Debenture consents to any and all extensions of time, renewals, waivers, or modifications, as well as to release, substitution, or addition of guarantors or collateral security, without affecting the Borrower’s liabilities hereunder. Lender is entitled to the benefits of any collateral agreement, guarantee, security agreement, assignment, or any other documents which may be related to or are applicable to the debt evidenced by this Debenture, all of which are collectively referred to as “Loan Documents” as they now exist, may exist in the future, have existed, and as they may be amended, modified, renewed, or substituted.

5. Representations and Warranties. The Borrower represents and warrants as follows:

6. Covenants. So long as any principal or interest is due hereunder and shall remain unpaid, the Borrower will, unless the Lender shall otherwise consent in writing:

(a) the nonpayment of principal, late charges or any other costs or expenses promptly when due of any amount payable under this Debenture or the nonpayment by the Borrower of any other obligation to the Lender;

(b) any default under any material or nonmaterial provision of this Debenture (other than a payment default described above);

(c) any failure of the Borrower to observe or perform any present or future agreement of any nature whatsoever with Lender, including, without limitation, any covenant set forth in this Debenture;

(i) the sale of all or substantially all of the assets, or change in ownership or the dissolution, liquidation, merger, consolidation, or reorganization of Borrower without the Lender’s written consent.

8. Lender’s Rights Upon Default. Upon the occurrence of any Event of Default, the Lender may, at its sole and exclusive option, do any or all of the following, either concurrently or separately: (a) accelerate the maturity of this Debenture and demand immediate payment in full, whereupon the outstanding principal amount of the Debenture and all obligations of Borrower to Lender, together with accrued interest thereon and accrued charges and costs, shall become immediately due and payable without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived; and (b) exercise all legally available rights and privileges.

9. Default Interest Rate. Upon an Event of Default, without any further action on the part of Lender, interest will thereafter accrue at the rate of eighteen percent (18%) per annum (the “Default Rate”), until all outstanding principal, interest and fees are repaid in full by Borrower.

10. Usury. In no event shall the amount of interest paid or agreed to be paid hereunder exceed the highest lawful rate permissible under applicable law. Any excess amount of deemed interest shall be null and void and shall not interfere with or affect the Borrower’s obligation to repay the principal of and interest on the Debenture. This confirms that the Borrower and, by its acceptance of this Debenture, the Lender intend to contract in strict compliance with applicable usury laws from time to time in effect. Accordingly, the Borrower and the Lender stipulate and agree that none of the terms and provisions contained herein shall ever be construed to create a contract to pay, for the use or forbearance of money, interest in excess of the maximum amount of interest permitted to be charged by applicable law from time to time in effect.

11. No Prepayment. This Debenture may not be prepaid in whole or in part, at any time, without the prior written consent of the Lender except pursuant to the provisions of section 2(e).

12. Costs of Enforcement. Borrower hereby covenants and agrees to indemnify, defend and hold Lender harmless from and against all costs and expenses, including reasonable attorneys’ fees and their costs, together with interest thereon at the Prime Rate, incurred by Lender in enforcing its rights under this Debenture; or if Lender is made a party as a defendant in any action or proceeding arising out of or in connection with its status as a lender, or if Lender is requested to respond to any subpoena or other legal process issued in connection with this Debenture; or reasonable disbursements arising out of any costs and expenses, including reasonable attorneys’ fees and their costs incurred in any bankruptcy case; or for any legal or appraisal reviews, advice or counsel performed for Lender following a request by Borrower for waiver, modification or amendment of this Debenture or any of the other Loan Documents.

13. Governing Law. This Debenture shall be binding upon and inure to the benefit of the Borrower and the Lender and their respective successors and assigns; provided that the Borrower may not assign this Debenture, in whole or in part, by operation of law or otherwise, without the prior written consent of the Lender. The Lender may assign or otherwise participate out all or part of, or any interest in, its rights and benefits hereunder and to the extent of such assignment or participation such assignee shall have the same rights and benefits against the Borrower as it would have had if it were the Lender. This Debenture, and any claims arising out of or relating to this Debenture, whether in contract or tort, statutory or common law, shall be governed exclusively by, and construed in accordance with the laws of the State of New York without regard to principles of conflicts of laws.

14. Jurisdiction. THE BORROWER CONSENTS THAT ANY LEGAL ACTION OR PROCEEDING AGAINST IT UNDER, ARISING OUT OF OR IN ANY MANNER RELATING TO THIS DEBENTURE, OR ANY OTHER INSTRUMENT OR DOCUMENT EXECUTED AND DELIVERED IN CONNECTION HEREWITH SHALL BE BROUGHT EXCLUSIVELY IN ANY COURT OF THE STATE OF NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE EASTERN DISTRICT OF NEW YORK, IN EACH CASE, IN THE COUNTY OF NASSAU. THE BORROWER, BY THE EXECUTION AND DELIVERY OF THIS DEBENTURE, EXPRESSLY AND IRREVOCABLY CONSENTS AND SUBMITS TO THE PERSONAL JURISDICTION OF ANY OF SUCH COURTS IN ANY SUCH ACTION OR PROCEEDINGS. THE BORROWER AGREES THAT PERSONAL JURISDICTION OVER IT MAY BE OBTAINED BY THE DELIVERY OF A SUMMONS BY PERSONAL DELIVERY OR OVERNIGHT COURIER AT THE ADDRESS PROVIDED IN SECTION 16 OF THIS DEBENTURE. ASSUMING DELIVERY OF THE SUMMONS IN ACCORDANCE WITH THIS PROVISION, THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY WAIVES ANY ALLEGED LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OF FORUM NON CONVENIENS OR ANY SIMILAR BASIS.

15. Miscellaneous.

(a) Borrower hereby waives protest, notice of protest, presentment, dishonor, and demand.

(b) Time is of the essence for each of Borrower’s covenants under this Debenture.

(c) The rights and privileges of Lender under this Debenture shall inure to the benefit of its successors and assigns. All obligations of Borrower in connection with this Debenture shall bind Borrower’s successors and assigns, and Lender’s conversion rights shall succeed to any successor securities to Borrower’s common stock.

(d) If any provision of this Debenture shall for any reason be held to be invalid or unenforceable, such invalidity or unenforceability shall not affect any other provision hereof, but this Debenture shall be construed as if such invalid or unenforceable provision had never been contained herein.

(e) The waiver of any Event of Default or the failure of Lender to exercise any right or remedy to which it may be entitled shall not be deemed a waiver of any subsequent Event of Default or Lender’s right to exercise that or any other right or remedy to which Lender is entitled. No delay or omission by Lender in exercising, or failure by Lender to exercise on any one or more occasions, shall be construed as a waiver or novation of this Debenture or prevent the subsequent exercise of any or all such rights.

(f) This Debenture may not be waived, changed, modified, or discharged orally, but only in writing.

16. Notice, Etc. Any notice required by the provisions of this Debenture will be in writing and will be deemed effectively given: (a) upon personal delivery to the party to be notified; (b) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient; if not, then on the next business day; (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (d) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt, and delivered as follows:
