Upon a mandatory redemption pursuant to this section 2.4(b), the Investor shall not in any event be required to return to the Company any fees or penalties paid by the Company to the Investor with respect to this Convertible Note. If the Company fails to timely redeem this Convertible Note in accordance with this subsection (b), then until the Company has redeemed this Convertible Note, the Company shall on the last Trading Day of each calendar month, or proportion thereof, beginning in the month in which this Convertible Note is required to be redeemed pursuant to this Section 2.4(b), pay to the Holder an additional amount of 2.0% of the outstanding principal balance of this Convertible Note.

Upon submitting a Conversion Notice in accordance with Section 3.2 hereof, the Holder has the right to require the Company to seek shareholder approval to permit the Company to convert this Convertible Note into a number of shares of Common Stock in excess of 19.9% of the Outstanding Common Stock of the Company, to the extent such shareholder approval is required by applicable rules of the Principal Market. If shareholder approval is obtained in accordance with Section 2.2 of the Securities Purchase Agreement, the Holder has the option of converting this Convertible Note, in accordance with Article 3 hereof, at either (i) the Conversion Price stated in the Conversion Notice or (ii) the Conversion Price as computed on the date such shareholder approval was obtained, which date for the purposes of this Section 2.5 shall be deemed the Conversion Date. If, within seventy-five (75) days of the Holder exercising its right to require the Company to seek shareholder approval, the Company should fail to obtain the requisite approval of shareholders, the Holder may require the Company to immediately redeem this Convertible Note at the Redemption Price, and only with respect to that portion of this Convertible Note which has not been previously converted or redeemed. Until the Company redeems this Convertible Note pursuant to this Section 2.5 and pays the Redemption Price to the Holder, the Company shall on the last Trading Day of each calendar month for the period beginning in the month this Convertible Note is required to be redeemed pursuant to this Section 2.5 and ending in the month prior to the month in which the Redemption Price is paid to the Holder, pay to the Holder an additional amount of 2.0% of such portion of the outstanding principal balance of this Convertible Note which, upon conversion of this Convertible Note, would be convertible into a number of shares of Common Stock in excess of 19.9% of the Outstanding Common Stock of the Company. SECTION 2.6. Notice of Redemption: Right to Convert in Lieu of Accepting Redemption. In the case of redemption of this Convertible Note, notice thereof shall be given in writing to the Holder not fewer than ten (10) Trading Days prior to the date fixed for such redemption (the "Redemption Date"). The redemption notice shall specify the Redemption Date and shall make reference to this Section 2.6 pursuant to which such redemption is to be made. Such notice of redemption and all other notices to be given to the Holder shall be given by facsimile and confirmed by registered mail at its designated address. Upon notice of any redemption being given as provided in this Section 2.6, the Holder shall have the right to exercise, either in whole or in part, the conversion privilege pursuant to Article 3 hereof until 5:00 P.M., New York City time, on the Trading Day preceding the Redemption Date.

Upon any partial redemption of this Convertible Note pursuant to this Article 2, the Holder at its option may (i) require the Company to issue and deliver, at the expense of the Company (other than for transfer taxes, if any), upon surrender of this Convertible Note, a new Convertible Note payable to such person or persons, or order, as may be designated by the Holder for the principal amount of this Convertible Note then remaining unredeemed, such Convertible Note to be dated as of the date of this Convertible Note, or (ii) present this Convertible Note to the Company for notation hereon of the payment of the portion of the principal amount so redeemed. The Company may, as a condition of payment of all or any of the principal of or interest on this Convertible Note, require the Holder to present this Convertible Note for notation of such payment and, if this Convertible Note be paid in full, require the surrender hereof. ARTICLE 3 CONVERSION OF NOTE SECTION 3.1. Conversion: Conversion Price. (a) At the option of the Holder, at any time until this Convertible Note is paid in full, this Convertible Note may be converted, either in whole or in part, up to the principal amount hereof, into shares of Common Stock. The conversion price ("Conversion Price") per share shall be equal to the lower of (i) the average of the Trade Prices during the ten (10) Trading Days immediately preceding the Closing Date and (ii) 93% of the Lowest Average Price during the Conversion Valuation Period. (b) During the term of this Convertible Note, the Company shall have the right to reject the conversion of all or part of this Convertible Note (as the case may be) if the applicable Conversion Price would be less than the Minimum Trade Price; provided, however, that the Company shall not be entitled to exercise such rejection right with respect to any subsequent conversions of all or part of this Convertible Note (as the case may be) if (x) the average of the Trade Prices during the seven (7) Trading Days immediately preceding the applicable Conversion Notice or Notices exceeds the Minimum Trade Price, or (y) the applicable Conversion Notice is delivered by facsimile to the Company more than 180 calendar days following the first exercise by the Company of its rejection right pursuant to this Section 3.1(b). (c) During the term of this Convertible Note, the Company shall have a further right to reject the conversion of all or part of this Convertible Note during the period in which there exists a Failed Registration Statement (as such term is defined in the Registration Rights Agreement) until the date on which the Registrable Securities may be sold by the Investor pursuant to Rule 144 (or any similar provision then in effect) under the Securities Act. (d) Notwithstanding anything to the contrary contained herein, on each Conversion Date, the number of Note Conversion Shares into which this Convertible Note may be converted shall not exceed the number of shares such that, when aggregated with all other shares of Common Stock and Registrable Securities then beneficially or deemed beneficially owned by the Holder, would result in the Holder owning more than 9.9% of all of such Common Stock as would be outstanding on such Conversion Date, as determined in accordance with Section 13(d) of the Exchange Act and the regulations promulgated thereunder. For purposes of this Section 3.1(c), in the event that the amount of Common Stock outstanding as determined in accordance with Section 13(d) of the Exchange Act and the regulations promulgated thereunder is greater on a Conversion Date than on the date upon which the Conversion Notice associated with such Conversion Date is given, the amount of Common Stock outstanding on such Conversion Date shall govern for purposes of determining whether the Holder would own more than 9.9% of the Common Stock following such Conversion Date. SECTION 3.2. Exercise of Conversion Privilege. (a) In order to convert this Convertible Note into Note Conversion Shares, the Holder shall on the Conversion Date send via facsimile, and in accordance with the notice provisions of Section 10.4 of the Securities Purchase Agreement, a copy of the fully executed Conversion Notice in the form attached hereto in Annex I (the "Conversion Notice") stating that the Holder elects to convert. The Conversion Notice shall specify (i) the Conversion Date, the (ii) portion of this Convertible Note to be converted, (iii) the applicable Conversion Price, (iv) the name or names (with address) of the persons who are to become holders of the Note Conversion Shares in connection with such conversion, and (v) a calculation of the number of Note Conversion Shares issuable upon such conversion. (b) Unless the Company agrees otherwise, the Holder shall not deliver more than one Conversion Notice per calendar week, or deliver a Conversion Notice requesting conversion of this Convertible Note for a principal amount of less than US$400,000; provided that the Holder shall have the right to deliver a Conversion Notice for the conversion of the then outstanding principal amount of this Convertible Note if such outstanding principal amount is less than US$400,000. (c) Upon receipt by the Company of a facsimile copy of a Conversion Notice, the Company shall immediately send, via facsimile, a confirmation of receipt of the Conversion Notice to the Holder. Such confirmation shall indicate that the Conversion Notice has been received and shall specify the name and telephone number of a contact person at the Company whom the Holder should contact regarding information related to the conversion of this Convertible Note. The Company shall not be obligated to issue certificates evidencing the Note Conversion Shares issuable upon conversion, unless either this Convertible Note is delivered to the Company as provided below, or the Holder notifies the Company that this Convertible Note has been lost, stolen or destroyed (subject to the requirements of Section 2.2). (d) Partial Conversion. Upon any partial conversion of this Convertible Note pursuant to this Article 3, the Holder at its option may (i) require the Company to issue and deliver, at the expense of the Company (other than for transfer taxes, if any), upon surrender of this Convertible Note, a new Convertible Note payable to such person or persons, or order, as may be designated by the Holder for the principal amount of this Convertible Note then remaining unconverted, such Convertible Note to be dated as of the date of this Convertible Note, or (ii) present this Convertible Note to the Company for notation hereon of the portion of the principal amount so converted.

The Company shall have the right to determine from which assets the Collateral shall be released, shall give written notice to the Holder describing such assets within fourteen (14) calendar days of such release, and shall amend Attachment A to the Security Agreement to reflect such release. (f) Release of Pledges. Upon written request of the Company, the Holder agrees to release the Pledges if the Effective Collateral exceeds 120% of the outstanding principal amount of the Convertible Notes. Such written request shall be accompanied by a certificate of an accountant confirming the value of the Distributable Collateral which can be distributed in accordance with sections 30 and 31 of the German Limited Liability Companies Act ("GmbHG") of as of the date of the request. After the release of the Pledges pursuant to the prior sentence and upon the Holder's request, the Company shall be required to provide the Holder with monthly certificates from a certified accountant setting forth the current details of the value of the Distributable Collateral. If at any time after the Pledges have been released, the outstanding principal amount of the Convertible Notes exceeds the Effective Collateral by more than [Euro] 100,000, the Company agrees to enter into a new pledge agreement on the same terms and conditions of the Pledge Agreement, with all costs and expenses relating to such pledge agreement to be borne by the Company.

The person or persons entitled to receive the Note Conversion Shares issuable upon conversion of this Convertible Note shall be treated for all purposes as the record holder or holders of such Note Conversion Shares on the Conversion Date. SECTION 1.4. Fractional Shares. No fractional Note Conversion Shares or scrip representing fractional Note Conversion Shares shall be issued upon conversion of this Convertible Note. If any conversion of this Convertible Note would create a fractional Note Conversion Share or a right to acquire a fractional Note Conversion Share, such fractional Note Conversion Share shall be disregarded and the number of Note Conversion Shares issuable upon conversion, in the aggregate, shall be the next higher number of shares. SECTION 1.5. Adjustment of Conversion Price. The Conversion Price and, accordingly, the number of Note Conversion Shares issuable upon the conversion of this Convertible Note shall be subject to adjustment from time to time upon the happening of certain events as follows: (a) Reclassification, Consolidation, Merger or Mandatory Share Exchange. (i) Upon occurrence of any of the events specified in subsection (a)(ii) below (the "Adjustment Events") while this Convertible Note remains outstanding and unexpired, the Company, or such successor or purchasing corporation, as the case may be, shall, without payment of any additional consideration therefore, execute a new Convertible Note providing that the Holder shall have the right to convert such new Convertible Note (upon terms not less favorable to the Holder than those then applicable to this Convertible Note) and to receive upon such exercise, in lieu of each Common Share theretofore issuable upon conversion of this Convertible Note, the kind and amount of shares of stock, other securities, money or property receivable upon such reclassification, change, consolidation, merger, mandatory share exchange, sale or transfer by the holder of one Common Share issuable upon conversion of this Convertible Note had this Convertible Note been converted immediately prior to such reclassification, change, consolidation, merger, mandatory share exchange or sale or transfer. Such new Convertible Note shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 3.5. (ii) The Adjustment Events include (1) any reclassification or change of Common Stock issuable upon conversion of this Convertible Note (other than a change in par value, or from par value to no par value per share, or from no par value per share to par value, or as a result of a subdivision or combination of outstanding Common Stock issuable upon conversion of this Convertible Note), (2) any consolidation, merger or mandatory share exchange of the Company with or into another corporation (other than a merger or mandatory share exchange with another corporation in which the Company is a continuing corporation and which does not result in any reclassification or change, other than a change in par value, or from par value to no par value per share, or from no par value per share to par value, or as a result of a subdivision or combination of Outstanding Common Stock issuable upon conversion of this Convertible Note), or (3) any sale or transfer to another corporation of the property of the Company as an entirety or substantially as an entirety. The provisions of this subsection (a) shall similarly apply to successive reclassifications, changes, consolidations, mergers, mandatory share exchanges and sales and transfers. (b) Subdivision or Combination of Shares. If the Company at any time while this Convertible Note remains outstanding and unexpired, shall subdivide or combine its Common Stock, the Conversion Price (i) shall be proportionately reduced, in case of subdivision of such shares, as of the effective date of such subdivision, or, if the Company shall take a record of holders of its Common Stock for the purpose of so subdividing, as of such record date, whichever is earlier, or (ii) shall be proportionately increased, in the case of combination of such shares, as of the effective date of such combination, or, if the Company shall take a record of holders of its Common Stock for the purpose of so combining, as of such record date, whichever is earlier. (c) Stock Dividends. If the Company at any time while this Convertible Note is outstanding and unexpired shall pay a dividend in its Capital Shares, or make any other distribution of its Capital Shares, then the Conversion Price shall be adjusted, as of the date the Company shall take a record of the holders of its Capital Shares for the purpose of receiving such dividend or other distribution (or if no such record is taken, as at the date of such payment or other distribution), to that price determined by multiplying the Conversion Price in effect immediately prior to such payment or other distribution by a fraction: (i) the numerator of which shall be the total number of Outstanding Capital Shares immediately prior to such dividend or distribution, and (ii) the denominator of which shall be the total number of Outstanding Capital Shares immediately after such dividend or distribution. The provisions of this subsection (c) shall not apply under any of the circumstances for which an adjustment is provided in subsections (a) or (b). (d) Issuance of Additional Capital Shares. If the Company at any time while this Convertible Note remains outstanding and unexpired shall issue any additional Capital Shares (the "Additional Capital Shares"), otherwise than as provided in the foregoing subsections (a) through (c) above, at a price per share less, or for other consideration lower, than the Conversion Price in effect immediately prior to such issuance, or without consideration, then upon such issuance the Conversion Price shall be reduced to that price determined by multiplying the Conversion Price in effect immediately prior to such event by a fraction: (i) the numerator of which shall be the number of Outstanding Capital Shares immediately prior to the issuance of the Additional Capital Shares plus the number of Capital Shares which the aggregate consideration for the total number of such Additional Capital Shares so issued would purchase at the then effective Conversion Price, and; (ii) the denominator of which shall be the number of Outstanding Capital Shares immediately after the issuance of the Additional Capital Shares plus the number of Additional Capital Shares so issued. The provisions of this subsection (d) shall not apply under any of the circumstances for which an adjustment is provided in subsections (a), (b) or (c). No adjustment of a Conversion Price shall be made under this subsection (d) upon the issuance of any Additional Capital Shares which are issued pursuant to the exercise of any warrants, options or other subscription or purchase rights or pursuant to the exercise of any conversion or exchange rights in any convertible or exchangeable securities if any such adjustments shall previously have been made upon the issuance of any such warrants, options or other rights or upon the issuance of any convertible or exchangeable securities (or upon the issuance of any warrants, options or any rights therefor) pursuant to subsection (e) or (f). (e) Issuance of Warrants, Options or Other Rights. If the Company at any time while this Convertible Note remains outstanding and unexpired shall issue any warrants, options (other than options under the Company's stock option plan) or other rights to subscribe for or purchase any Additional Capital Shares and the price per share for which Additional Capital Shares may at any time thereafter be issuable pursuant to such warrants, options or other rights shall be less than the Conversion Price in effect immediately prior to such issuance, then upon such issuance the Conversion Price shall be adjusted as provided in subsection (d) hereof on the basis that: (i) the maximum number of Additional Capital Shares issuable pursuant to all such warrants, options or other rights shall be deemed to have been issued as of the date of actual issuance of such warrants, options or other rights, and (ii) the aggregate consideration for such maximum number of Additional Capital Shares issuable pursuant to such warrants, options or other rights, shall be deemed to be the consideration received by the Company for the issuance of such warrants, options, or other rights plus the minimum consideration to be received by the Company for the issuance of Additional Capital Shares pursuant to such warrants, options, or other rights. (f) Issuance of Convertible or Exchangeable Securities. If the Company at any time while this Convertible Note remains outstanding and unexpired shall issue any securities convertible into or exchangeable for Capital Shares and the consideration per share for which Additional Capital Shares may at any time thereafter be issuable pursuant to the terms of such convertible or exchangeable securities shall be less than the Conversion Price in effect immediately prior to such issuance, then upon such issuance the Conversion Price shall be adjusted as provided in subsection (d) hereof on the basis that: (i) the maximum number of Additional Capital Shares necessary to effect the conversion or exchange of all such convertible or exchangeable securities shall be deemed to have been issued as of the date of issuance of such convertible or exchangeable securities, and (ii) the aggregate consideration for such maximum number of Additional Capital Shares shall be deemed to be the consideration received by the Company for the issuance of such convertible or exchangeable securities plus the minimum consideration received by the Company for the issuance of such Additional Capital Shares pursuant to the terms of such convertible or exchangeable securities. No adjustment of the Conversion Price shall be made under this subsection (f) upon the issuance of any convertible or exchangeable securities which are issued pursuant to the exercise of any warrants, options or other subscription or purchase rights therefor, if any such adjustment shall previously have been made upon the issuance of such warrants, options or other rights pursuant to subsection (e) hereof. (g) Adjustment of Number of Shares. Upon each adjustment of the Conversion Price pursuant to any provisions of this Section 3.5, the number of Note Conversion Shares issuable hereunder at the option of the Holder shall be calculated, to the next higher whole share, to be the quotient obtained by dividing (i) the then outstanding principal amount of this Convertible Note by (ii) the Conversion Price immediately after such adjustment. (h) Liquidating Dividends, Etc. If the Company at any time while this Convertible Note is outstanding and unexpired makes a distribution of its assets or evidences of indebtedness to the holders of its Capital Shares as a dividend in liquidation or by way of return of capital or other than as a dividend payable out of earnings or surplus legally available for dividends under applicable law or any distribution to such holders made in respect of the sale of all or substantially all of the Company's assets (other than under the circumstances provided for in the foregoing subsections (a) through (g)), provided, in each case, that such distribution described in this subsection (h) does not constitute an Event of Default hereunder, the Holder shall be entitled to receive upon the conversion of this Convertible Note, in addition to the Note Conversion Shares receivable upon such exercise, and without payment of any consideration other than the Conversion Price, an amount in cash equal to the value of such distribution per Capital Share multiplied by the number of Note Conversion Shares which, on the record date for such distribution, are issuable upon Conversion of this Convertible Note (with no further adjustment being made following any event which causes a subsequent adjustment in the number of Note Conversion Shares issuable upon the exercise hereof), and an appropriate provision therefor shall be made a part of any such distribution. The value of a distribution which is paid in other than cash shall be determined in good faith by the Board of Directors. (i) Other Provisions Applicable to Adjustments Under this Section. The following provisions will be applicable to the making of adjustments in a Conversion Price hereinabove provided in this Section 3.5: (i) Computation of Consideration. To the extent that any Additional Capital Shares or any convertible or exchangeable securities or any warrants, options or other rights to subscribe for or purchase any Additional Capital Shares or any convertible or exchangeable securities shall be issued for a cash consideration, the consideration received by the Company therefor shall be deemed to be the amount of the cash received by the Company therefor, or, if such Additional Capital Shares or convertible or exchangeable securities are offered by the Company for subscription, the subscription price, or, if such Additional Capital Shares or convertible or exchangeable securities are sold to underwriters or dealers for public offering without a subscription offering, or through underwriters or dealers for public offering without a subscription offering, the initial public offering price, in any such case excluding any amounts paid or incurred by the Company for and in the underwriting of, or otherwise in connection with the issue thereof. To the extent that such issuance shall be for a consideration other than cash, then, the amount of such consideration shall be deemed to be the fair value of such consideration at the time of such issuance as determined in good faith by the Company's Board of Directors. The consideration for any Additional Capital Shares issuable pursuant to any warrants, options or other rights to subscribe for or purchase the same shall be the consideration received by the Company for issuing such warrants, options or other rights, plus the additional consideration payable to the Company upon the exercise of such warrants, options or other rights. The consideration for any Additional Capital Shares issuable pursuant to the terms of any convertible or exchangeable securities shall be the consideration paid or payable to the Company in respect of the subscription for or purchase of such convertible or exchangeable securities, plus the additional consideration, if any, payable to the Company upon the exercise of the right of conversion or exchange in such convertible or exchangeable securities. In case of the issuance at any time of any Additional Capital Shares or convertible or exchangeable securities in payment or satisfaction of any dividend upon any class of stock preferred as to dividends in a fixed amount, the Company shall be deemed to have received for such Additional Capital Shares or convertible or exchangeable securities a consideration equal to the amount of such dividend so paid or satisfied. (ii) Readjustment of Conversion Price. Upon the expiration of the right to convert or exchange any convertible or exchangeable securities, or upon the expiration of any rights, options or warrants, the issuance of which convertible or exchangeable securities, rights, options or warrants effected an adjustment in a Conversion Price, if any such convertible or exchangeable securities shall not have been converted or exchanged, or if any such rights, options or warrants shall not have been exercised, the number of Capital Shares deemed to be issued and Outstanding by reason of the fact that they were issuable upon conversion or exchange of any such convertible or exchangeable securities or upon exercise of any such rights, options, or warrants shall no longer be computed as set forth above, and such Conversion Price shall forthwith be readjusted and thereafter be the price which it would have been (but reflecting any other adjustments in the Conversion Price made pursuant to the provisions of this Section 3.5 after the issuance of such convertible or exchangeable securities, rights, options or warrants) had the adjustment of the Conversion Price made upon the issuance or sale of such convertible or exchangeable securities or issuance of rights, options or warrants been made on the basis of the issuance only of the number of Additional Capital Shares actually issued upon conversion or exchange of such convertible or exchangeable securities, or upon the exercise of such rights, options or warrants, and thereupon only the number of Additional Capital Shares actually so issued, if any, shall be deemed to have been issued and only the consideration actually received by the Company (computed as set forth in sub-subsection (i) hereof) shall be deemed to have been received by the Company. If the purchase price provided for in any rights, options or warrants, or the additional consideration (if any) payable upon the conversion or exchange of any convertible or exchangeable securities, or the rate at which any convertible or exchangeable securities are convertible into or exchangeable for Capital Shares changes at any time (other than under or by reason of provisions designed to protect against dilution), the Conversion Price in effect at the time of the change shall be adjusted to the Conversion Price that would have been in effect at such time had such rights, options, warrants or convertible or exchangeable securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold. (iii) Other Action Affecting Capital Shares. In case after the date hereof the Company shall take any action affecting the number of Outstanding Capital Shares, other than an action described in any of the foregoing subsections (a) through (h) hereof, inclusive, which in the opinion of the Company's Board of Directors would have a Materially Adverse Effect upon the rights of the Holder at the time of a conversion of this Convertible Note, the Conversion Price shall be adjusted in such manner and at such time as the Board or Directors on the advice of the Company's independent public accountants may in good faith determine to be equitable in the circumstances. SECTION 1.6. Notice of Adjustments. Whenever the Conversion Price under the terms of this Convertible Note shall be adjusted pursuant to Section 3.5 hereof, the Company shall promptly issue a certificate signed by its President or a Vice President and by its Treasurer or Assistant Treasurer or its Secretary or Assistant Secretary, setting forth in reasonable detail (i) the event requiring the adjustment, (ii) the amount of the adjustment, (iii) the method by which such adjustment was calculated (including a description of the basis on which the Company's Board of Directors made any determination hereunder), and (iv) the Conversion Price and number of Note Conversion Shares purchasable at that Conversion Price after giving effect to such adjustment.
