No fractional shares of Common Stock shall be issued. Upon conversion of this Debenture, fractional shares, if applicable, shall be paid in cash based on the Conversion Price. (b) For purposes hereof, the term "Conversion Price" shall mean initially $_______per share. [120% of the average closing bid price for the twenty days prior to closing], and shall be subject to adjustment, as follows: (i) In case the Issuer shall at anytime hereafter subdivide or combine the outstanding shares of Common Stock or declare a dividend payable in Common Stock, the Conversion Price in effect immediately prior to the subdivision, combination or record date for such dividend payable in Common Stock shall forthwith be proportionately increased, in the case of combination, or decreased, in the case of subdivision or dividend payable in Common Stock, and each share of Common Stock issuable upon conversion of this Debenture shall be changed to the number determined by dividing the then current Conversion Price by the Conversion Price as adjusted after the subdivision, combination, or dividend payable in Common Stock. (ii) If any capital reorganization or reclassification of the capital stock of the Issuer, or consolidation or merger of the Issuer with another corporation, or the sale of all or substantially all of its assets to another corporation shall be effected in such a way that holders of Common Stock shall be entitled to receive stock, securities or assets with respect to or in exchange for Common Stock, then, as a condition of such reorganization, reclassification, consolidation, merger or sale, lawful and adequate provision shall be made whereby the holder hereof shall hereafter have the right to receive upon the basis and upon the terms and conditions specified in this Debenture and in lieu of the shares of the Common Stock of the Issuer into which this Debenture was immediately theretofore convertible, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such stock into which this Debenture was immediately theretofore convertible had such reorganization, reclassification, consolidation, merger or sale not taken place, and in any such case appropriate provisions shall be made with respect to the rights and interests of Holder to the end that the provisions hereof (including without limitation provisions for adjustments of the Conversion Price and of the number of shares into which this Debenture may be converted) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities or assets thereafter deliverable upon the conversion hereof. The Issuer shall not effect any such 4 consolidation, merger or sale, unless prior to the consummation thereof the successor corporation (if other than the Issuer) resulting from such consolidation or merger or the corporation purchasing such assets shall assume by written instrument executed and mailed to the registered holder hereof at the last address of such holder appearing on the books of the Issuer, the obligation to deliver to such holder such shares of stock, securities or assets into which, in accordance with the foregoing provisions, such holder may be entitled to convert this Debenture. (iii) If the Issuer distributes to all holders of Common Stock any assets (excluding ordinary cash dividends) or debt securities or any rights or warrants to purchase debt securities, assets or other securities (including Common Stock), the Conversion Price shall be adjusted in accordance with the formula: C(1) = C x (O x M) - F --------------- O x M where: C(1) = the adjusted Conversion Price. C = the current Conversion Price. M = the average market price of Common Stock for the 30 consecutive trading days commencing 45 trading days before the record date mentioned below. O = the number of shares of Common Stock outstanding on the record date mentioned below. F = the fair market value on the record date of the aggregate of all assets, securities, rights or warrants distributed. The Issuer's Board of Directors shall determine the fair market value in the exercise of its reasonable judgment. The adjustment shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of stockholders entitled to receive the distribution. 5 (iv) If the Issuer issues or sells any shares of Common Stock for a consideration per share less than the Conversion Price then in effect (other than dividends payable in shares of Common Stock), or issues any options, warrants, or other rights to purchase Common Stock at a consideration per share less than the Conversion Price then in effect, or issues securities convertible into Common Stock at a conversion price per share of less than the Conversion Price then in effect, then the Conversion Price in effect immediately prior to such issuance or sale shall be adjusted by multiplying such Conversion Price by a fraction, (a) the numerator of which shall be an amount equal to the sum of (A) the aggregate number of shares of Common Stock outstanding immediately prior to such issuance or sale multiplied by the applicable Conversion Price in effect immediately prior to such issuance or sale, and (B) the total consideration payable to the Issuer upon such issuance or sale of such Common Stock and/or such purchase rights or convertible securities, plus the consideration payable to the Issuer upon the exercise of such purchase rights or upon conversion of such convertible securities, and (b) the denominator of which shall be an amount equal to the aggregate number of shares of Common Stock outstanding immediately after such issuance or sale plus the number of shares of Common Stock issuable upon the exercise of any purchase rights and/or upon the conversion of convertible securities issued in such issuance. If the Conversion Price is adjusted as the result of the issuance of any options, warrants or other purchase rights or upon the issuance of convertible securities, no further adjustments of such Conversion Price shall be made at the time of the exercise of such options, warrants or other purchase rights or convertible securities. If securities are sold for a consideration other than cash, the amount of the consideration other than cash received by the Issuer shall be deemed to be the fair value of such consideration as determined by the Board of Directors of the Issuer. (v) Upon any adjustment of the Conversion Price, then and in each such case, the Issuer shall give written notice thereof, by first class mail, postage prepaid, addressed to the registered holder of this Debenture at the address of such holder as shown on the books of the Issuer, which notice shall state the Conversion Price resulting from such adjustment and the increase or decrease, if any, in the number of shares into which this Debenture may be converted, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. (c) The number of shares of Common Stock to be received upon conversion of this Debenture shall be equal to (x) the principal amount of this Debenture, divided by (y) the per share Conversion Price. Conversion shall be effected by the Holder completing and duly executing the conversion election form attached hereto (the "Conversion Election") and surrendering this Debenture, together with such Conversion Election, to the Issuer at its 6 principal office on or before the date for such conversion stated in the Conversion Election or before the Redemption Date stated in the Redemption Notice. This Debenture, or any part thereof called for redemption, must be covered in whole and not in part. (d) As soon as practicable after the receipt of the Conversion Election, the Company will cause to be issued in the name of and delivered to the Holder hereof, or as such Holder may direct, a certificate or certificates representing the shares of Common Stock acquired upon such exercise. No fractional shares of Common Stock shall be issued; in lieu of any fractional shares to which the Holder would otherwise be entitled, the Company shall pay cash equal to such fraction multiplied by the then effective Conversion Price. The Company shall also pay the Holder an amount equal to the interest accrued on the Debenture to the date of conversion. (e) Any shares of Common Stock issued upon conversion shall not be freely tradeable and shall be "restricted shares," shall be subject to the same restrictions on transfer as are the Debentures, and the certificate therefor shall contain a legend in substantially the form set forth on the face of this Debenture. In addition, all shares of Common Stock so issued shall be entitled to certain registration rights, as set forth herein and limited hereby. (f) A number of shares of Common Stock sufficient to provide for the exercise of the conversion rights upon the basis herein set forth shall at all items be reserved for the exercise thereof, subject to any required action of the shareholders. If any such shareholder action is required, the Issuer shall use its best efforts to cause such action to be taken. 5. SUBORDINATION. This Debenture is not, nor shall it ever be, secured by any collateral and is not, nor shall it ever be, the subject of any guaranty. The Subordinate Obligations are and shall be expressly subordinate and junior in right of payment to all Senior Secured Obligations until the Senior Secured Obligations have been Paid In Full. Holder's interest in and to the payment of principal, interest and premium or any other amounts due hereunder, is subordinate to the interest of the Senior Lender and subject to the terms of this Agreement. The Senior Lender has advanced funds and may from time to time advance additional funds in reliance upon the subordination of the Subordinate Obligations to the Senior Secured Obligations. Holder agrees to be fully unsecured with respect to the Subordinate Obligations and, to that end, Holder agrees to execute, file and/or record all such releases, termination statements and satisfactions as are requested by the Senior Lender in order to cause the Subordinate Obligations to be fully unsecured. 6.

(d) Any representation or warranty made by or on behalf of the Issuer in this Debenture or in any certificate or other instrument delivered under or pursuant to any term hereof shall prove to have been untrue or incorrect in any material respect as of the date such representation or warranty was made or if any certificate, financial statement or financial schedule or other instrument prepared by the Issuer or any executive officer of the Issuer furnished or delivered under or pursuant to this Debenture after the date hereof shall prove to be untrue or incorrect in any material respect as of the date it was made, furnished or delivered.

Upon the occurrence of an Event of Default, then not fewer than three Holders holding not less than an aggregate of twenty-five percent (25%) of the principal amount of the Debentures then outstanding may declare immediately due and payable the outstanding amounts under all the Debentures, and the same shall thereupon be immediately due and payable, and, subject to the terms contained in Sections 7 and 8 hereof, may exercise any and all remedies available under Illinois law or in equity. Upon the occurrence of an Event of Default as described in Section 6(e) hereof, the Holder hereof shall have the option to declare the principal amount hereof, and all accrued but unpaid interest thereon, to be immediately due and payable upon written notice from the Holder to the Issuer and, subject to the terms contained in Sections 7 and 8 hereof, to exercise any and all remedies available to it under Illinois law or at equity. 7.

(g) Nothing in this Agreement shall restrict the ability of the Senior Lender to declare a default, accelerate all or any portion of the Senior Secured Obligations and/or exercise any and all rights and remedies contained in the Senior Loan Documents. 10 8. PERMITTED PAYMENTS; RIGHT TO RETAIN PAYMENTS.

REGISTRATION RIGHTS. The Holder acknowledges and understands that the shares of Common Stock to be issued hereunder are not required to be registered under any securities laws except as set forth below. If such shares are not so registered, they will be "restricted securities" as that term is used under the Securities Act of 1933, as amended (the "Securities Act"), and the transferability and liquidity will be substantially restricted by federal and state securities laws and will bear a legend comparable to that set forth on the first page hereof. (a) On or before the nine-month anniversary of the date hereof, the Company shall file a registration statement under the Securities Act covering the sale of the Shares of Common Stock issuable upon conversion of the Debentures. The Company shall use its best efforts to have such registration statement declared effective by the Securities and Exchange Commission (the "Commission") by the twelve-month anniversary of the date hereof. The costs and expenses directly related to such registration, including but not limited to legal fees of the Company's counsel, audit fees, printing expense, filing fees and fees and expenses relating to qualifications under state securities or blue sky laws incurred by the Company shall be borne entirely by the Company; provided, however, that the persons for whose account the securities covered by such registration are sold shall bear the underwriting commissions, if any, applicable to their shares and fees of their legal counsel. If the holders of shares of Common Stock underlying the Debentures are the only persons whose shares are included in the registration pursuant to this section, such holders shall bear the expense of inclusion of audited financial statements in the registration statement which are not dated as of the Company's normal fiscal year or are not otherwise prepared by the Company for its own business purposes. The Company shall keep effective and maintain such registration statement for such period as may be necessary for the holders of such common stock to dispose of such securities and, from time to time shall amend or supplement, at the holder's expense, the prospectus or offering circular used in connection 15 therewith to the extent necessary in order to comply with applicable law; provided, that the Company shall not be required to maintain the effectiveness of such registration statement once holders of the Debentures can sell the shares underlying the Debentures under Rule 144(k) or any successor thereto under the Securities Act. (b) The managing underwriter of an offering registered pursuant to Section 14(a), if any, shall be selected by the holders of a majority of the shares issued or issuable upon the conversion of the Debentures for which registration has been requested and shall be reasonably acceptable to the Company. Without the written consent of the holders of a majority of the shares issued or issuable upon the exercise of the Debentures for which registration has been requested pursuant to this Section 14(b), neither the Company nor any other holder of securities of the Company may include securities in such registration if in the good faith judgment of the managing underwriter of such public offering the inclusion of such securities would interfere with the successful marketing of the share issued upon the conversion of the Debentures or require the exclusion of any portion of the shares issued upon the exercise of the Debentures to be registered. (c) If the Company proposes to claim an exemption under Section 3(b) of the Securities Act for a public offering of any of its securities or to register under the Securities Act (except by a claim of exemption or registration statement on a form that does not permit the inclusion of shares by its security holders) any of its securities, it will give written notice to all registered holders of the Debentures, and all registered holders of shares of Common Stock acquired upon the conversion of Debentures, of its intention to do so and, on the written request of any such registered holders given within twenty (20) days after receipt of any such notice (which request must be made within seven (7) years from the date of this Debenture), the Company will use its best efforts to cause all such shares, the registered holders of which shall have requested the registration or qualification thereof, to be included in such notification or registration statement proposed to be filed by the Company; provided, however, that (i) the Company shall not be required to include any such shares of Common Stock in any such registration for any holder who is able to sell all shares of Common Stock owned by such holder (or issuable to such holder upon conversion of this Debenture), and which benefit from the registration rights granted hereunder, during the three-month period beginning on the date such notice is received by such holder, without compliance with the registration requirements of the Securities Act pursuant to Rule 144(k) or any successor thereto under the Securities Act; (ii) the Company shall not be required to give such notice with respect to, or to include such Common Stock in, any such registration which is primarily (A) a registration of a stock option plan or other employee benefit plan or of securities issued or issuable pursuant to any such plan such as a registration on Form S-8, or (B) a registration of securities proposed to be issued in exchange for securities or assets of, or in connection with a merger or consolidation with, another corporation such as a registration on Form S-4; (iii) the Company shall not be required to include in any such registration any shares of Common Stock previously duly registered under the Securities Act; (iv) the Company may, in its sole discretion, withdraw any such registration statement and abandon the proposed offering in which any such holder had requested to participate; 16 (v) if the offering to which the registration statement relates is to be distributed by or through an underwriter, each such holder shall agree, as a condition to the inclusion of such holder's securities in such registration, to sell the securities held by such holder through such underwriter on the same terms and conditions as the underwriter agrees to sell securities on behalf of the Company and not to sell, transfer, pledge, assign or otherwise dispose of any shares of Common Stock not sold by such holder in such offering for such period (up to (90) days after the effective date of the registration statement) as may be required by the underwriter; and (vi) if the offering to which the registration statement relates is to be distributed by or through an underwriter and a greater number of securities is offered for participation in the proposed underwriting than, in the opinion of the Company's underwriter, can be accommodated without significantly adversely affecting the proposed underwriting, the amount of such securities otherwise to be included in the underwritten offering on behalf of all persons other than the Company may be reduced pro rata, in accordance with the number of shares of Common Stock proposed to be sold by each such holder, or may be eliminated entirely from such underwritten public offering. The costs and expenses of such offering, including but not limited to legal fees, special audit fees, printing expenses, filing fees, fees and expenses relating to qualifications under state securities or blue sky laws and the premiums for insurance, if any, incurred by the Company in connection with any registration made pursuant to this Section 14(c) shall be borne entirely by the Company; PROVIDED, HOWEVER, that any holders participating in such registration shall bear their own underwriting discounts and commissions and the fees and expenses of their own counsel or accountants in connection with any such registration. (d) In connection with the filing of a registration statement under Sections 14(a) and (c) hereof, the Company shall: (i) prepare and file with the U.S. Securities and Exchange Commission (the "Commission") such amendments to such registration statement and supplements to the prospectus contained therein as may be necessary to keep such registration statement effective until holders of the Debentures can sell the shares underlying the Debentures without restriction under Rule 144(k) or any successor thereto under the Securities Act; (ii) furnish to the security holders participating in such registration and to the underwriters of the securities being registered such reasonable number of copies of the registration statement, preliminary prospectus, final prospectus and such other documents as such underwriters may reasonably request in order to facilitate the public offering of such securities; (iii) use its best efforts to register or qualify the securities covered by such registration statement under such state securities or blue sky laws of such jurisdictions as such participating holders may reasonably request in writing within thirty (30) days following the original filing of such registration statement, except that the Company shall not for any purpose be required to execute a general consent 17 to service of process or to qualify to do business as a foreign corporation in any jurisdiction wherein it is not so qualified; (iv) notify the security holders participating in such registration, promptly after it shall receive notice thereof, of the time when such registration statement has become effective or a supplement to any prospectus forming a part of such registration statement has been filed; (v) notify such holders promptly of any request by the Commission for the amending or supplementing of such registration statement or prospectus or for additional information; (vi) prepare and file with the Commission, promptly upon the request of any such holders, any amendments or supplements to such registration statement or prospectus which, in the opinion of counsel for such holders (and concurred in by counsel for the Company), is required under the Securities Act or the rules and regulations thereunder in connection with the distribution of the shares by such holder; (vii) prepare and promptly file with the Commission and promptly notify such holders of the filing of such amendment or supplement to such registration statement or prospectus as may be necessary to correct any statements or omissions if, at the time when a prospectus relating to such securities is required to be delivered under the Securities Act, any event shall have occurred as the result of which any such prospectus or any other prospectus as then in effect would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading; (viii) advise such holders, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such registration statement or the initiation or threatening of any proceeding for that purpose and promptly use its best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued; (ix) not file any amendment or supplement to such registration statement or prospectus to which a majority in interest of such holders shall have reasonably objected on the grounds that such amendment or supplement does not comply in all material respects with the requirements of the Securities Act or the rules and regulations thereunder, after having been furnished with a copy thereof at least five (5) business days prior to the filing thereof, unless in the opinion of counsel for the Company the filing of such amendment or supplement is reasonably necessary to protect the Company from any liabilities under any applicable federal or state law and such filing will not violate applicable law; and 18 (x) at the request of any such holder, furnish on the effective date of the registration statement and, if such registration includes an underwritten public offering, at the closing provided for in the underwriting agreement: (i) opinions, dated such respective dates, of the counsel representing the Company for the purposes of such registration, addressed to the underwriters, if any, and to the holder or holders making such request, covering such matters as such underwriters and holder or holders may reasonably request; and (ii) letters, dated such respective dates, from the independent certified public accountants of the Company, addressed to the underwriters, if any, and to the holder or holders making such request, covering such matters as such underwriters and holder or holders may reasonably request, in which letter such accountants shall state (without limiting the generality of the foregoing) that they are independent certified public accountants within the meaning of the Securities Act and that in the opinion of such accountants the financial statements and other financial data of the Company included in the registration statement or the prospectus or any amendment or supplement thereto comply in all material respects with the applicable accounting requirements of the Securities Act. (e) The Company hereby indemnifies the holder of this Debenture and of any common stock issued or issuable hereunder, its officers and directors, and any person who controls such Debenture holder or such holder of common stock within the meaning of Section 15 of the Securities Act, against all losses, claims, damages and liabilities caused by any untrue statement of a material fact contained in any registration statement, prospectus, notification or offering circular (and as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus or caused by any omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading except insofar as such losses, claims, damages or liabilities are caused by any untrue statement or omission contained in information furnished in writing to the Company by such holder or such holder of Common Stock expressly for use therein, and each such holder by its acceptance hereof severally agrees that it will indemnify and hold harmless the Company and each of its officers who signs such registration statement and each of its directors and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act with respect to losses, claims, damages or liabilities which are caused by any untrue statement or omission contained in information furnished in writing to the Company by such holder expressly for use therein.
