CONVERTIBLE PROMISSORY NOTE

FOR VALUE RECEIVED, the undersigned, Tarsier, Ltd., a Delaware corporation (referred to herein as the "Borrower"), with offices at 475 Park Avenue South, 30th Floor, New York, NY 10016 hereby unconditionally promises to pay to the order of DemanSYS Energy Inc., its endorsees, successors and assigns (the "Lender"), in lawful money of the United States, at such address as the Lender may from time to time designate, the principal sum of four hundred fifty thousand dollars ($450,000.00) (the "Loan"). This Convertible Promissory Note (the "Note") shall mature and become due and payable in full in four payments (the ''Maturity Dates").

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

2.          Conversion.

(a) Only upon default the Lender shall have the option to convert any or all of the outstanding principal and interest of portion of the Note from the second and third maturity date into fully- paid and non-assessable shares of Borrower's Common Stock at a Twenty Percent (30%) discount to the "Fair Market Value" (the "Conversion Rate"). In no case shall the conversion price be less than One tenth of One Cent ($0.001). "Fair Market Value" on a date shall be the lowest closing bid price for the Five (5) days immediately preceding the date of conversion excluding any trades which are not bona fide arm's length transactions. The closing price for each day shall be (a) if such security is listed or admitted for trading on any national securities exchange, the last sale price of such security, regular way, or the mean of the closing bid and asked prices thereof if no such sale occurred, in each case as officially reported on the principal securities exchange on which such security are listed, or (b) if quoted on NASDAQ or any similar system of automated dissemination of quotations of securities prices then in common use the mean between the closing high bid and low asked quotations of such security in the over-the-counter market as shown by NASDAQ or such similar system of automated dissemination of quotations of securities prices, as reported by any member firm of the New York Stock Exchange selected by the Lender, (c) if not quoted as described in clause (b), the mean between the high bid and low asked quotations for the shares as reported by NASDAQ or any similar successor organization, as reported by any member firm of the New York Stock Exchange selected by the Lender. If such security is quoted on a national securities or central market system in lieu of a market or quotation system described above, the closing price shall be determined in the manner set forth in clause (a) of the preceding sentence if bid and asked quotations are reported but actual transactions are not, and in the manner set forth in clause (b) of the preceding sentence if actual transactions are reported.

(b) In no event shall the Lender be entitled to convert any portion of this Note in excess of that portion of this Note upon conversion of which the sum of (1) the number of shares of Common Stock beneficially owned by the Lender and its affiliates (other than shares of Common Stock which may be deemed beneficially owned through the ownership of the unconverted portion of the Notes or the unexercised or unconverted portion of any other security of the Borrower subject to a limitation on conversion or exercise analogous to the limitations contained herein) and (2) the number of shares of Common Stock issuable upon the conversion of the portion of this Note with respect to which the determination of this proviso is being made, would result in beneficial ownership by the Holder and its affiliates of more than Four Point Nine Nine Percent (4.99%) of the outstanding shares of Common Stock. For purposes of the proviso to the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Regulations 13D-G thereunder, except as otherwise provided in clause (1) of such proviso.

(c) To exercise any conversion, the holder of this Note shall surrender the Note 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.

(d) As promptly as practicable after the surrender of this Note 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 Note in accordance with the provisions hereof, together with a duly executed new Note of the Borrower in the form of this Note for any principal amount not so converted. Such conversion shall be deemed to have been made at the time that this Note was surrendered for conversion and the notice specified herein shall have been received by the Borrower.

(e) The number of shares issuable upon conversion of this Note 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 Note 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 Note 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.

(f) The Borrower hereby agrees to hold on reserve Two Hundred Percent (200%) of the number of shares (the "Reserve Shares") that this Note can be converted into at all times and shall increase the Reserve Shares as required from time to time. The Borrower shall also provide irrevocable authorization to its Transfer Agent to issue such amount of Reserve Shares demanded by the Lender, pursuant to a Notice of Conversion, should the Borrower be in Default as defined below. Borrower hereby agrees not to cancel, put a stop order or otherwise encumber or limit the ability of the Lender to transfer the common shares owned by the Lender pursuant to any notice of conversion.

3.          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 Note and such liability shall not be affected by an extension of time, renewal, waiver, or modification of this Note or the release, substitution, or addition of collateral for this Note. Each person signing this Note 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.

13.         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 Note; 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 Note; 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 Note or any of the other Loan Documents.

14.         Governing Law. This Note 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 Note, 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 Note, and any claims arising out of relating to this Note, 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.

15.         Jurisdiction. THE BORROWER CONSENTS THAT ANY LEGAL ACTION OR PROCEEDING AGAINST IT UNDER, ARISING OUT OF OR IN ANY MANNER RELATING TO THIS NOTE, OR ANY OTHER INSTRUMENT OR DOCUMENT EXECUTED AND DELIVERED IN CONNECTION HEREWITH SHALL BE BROUGHT EXCLUSNELY IN ANY COURT OF THE STATE OF NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK. THE BORROWER, BY THE EXECUTION AND DELIVERY OF THIS NOTE, EXPRESSLY AND IRREVOCABLY CONSENTS AND SUBMITS TO THE PERSONAL JURISDICTION OF ANY OF SUCH COURTS IN ANY SUCH ACTION OR PROCEEDINGS.

(c) The rights and privileges of Lender under this Note shall inure to the benefit of its successors and assigns. All obligations of Borrower in connection with this Note 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 Note shall for any reason be held to be invalid or unenforceable, such invalidity or unenforceability shall not affect any other provision hereof, but this Note 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 anyone or more occasions, shall be construed as a waiver or novation of this Note or prevent the subsequent exercise of any or all such rights.
