If on any Conversion Date: (A) the aggregate number of shares of Common Stock that would then be issuable upon conversion in full of all then outstanding principal amount of Debentures would exceed the Issuable Maximum, and (B) the Company shall not have previously obtained the vote of shareholders, as may be required by the applicable rules and regulations of the Nasdaq Stock Market (or any successor entity) applicable to approve the issuance of shares of Common Stock in excess -12- of the Issuable Maximum pursuant to the terms hereof (the "SHAREHOLDER APPROVAL"), then, the Company shall issue to the converting Holder a number of shares of Common Stock equal to such Holder's pro-rata portion (which shall be calculated pursuant to the terms hereof) of the Issuable Maximum and, with respect to the remainder of the principal amount of Debentures then held by such Holder for which a conversion would result in an issuance of shares of Common Stock in excess of such Holder's pro-rata portion (which shall be calculated pursuant to the terms hereof) of the Issuable Maximum (the "EXCESS PRINCIPAL AMOUNT "), the applicable Holder shall have the right to require the Company to either: (1) obtain the Shareholder Approval applicable to such issuance as soon as is possible, but in any event not later than the 90th day after such request, or (2) pay cash, in an amount equal to the Excess Principal Amount (and accrued and unpaid dividends thereon). If a Holder shall have elected the first option pursuant to the immediately preceding sentence and the Company shall have failed to obtain the Shareholder Approval on or prior to the 90th day after such request, then within three (3) days of such 90th day, the Company shall pay cash to such Holder an amount equal to Excess Principal Amount (and accrued and unpaid dividends thereon). If the Company fails to pay the Excess Principal Value in full pursuant to this Section within seven days after the date payable, the Company will pay interest thereon at a rate of 15% per annum or such lesser maximum amount that is permitted to be paid by applicable law, to such Holder, accruing daily from the Conversion Date until such amount, plus all such interest thereon, is paid in full. Notwithstanding anything herein to the contrary, if on any date other than a Conversion Date: (A) the aggregate number of shares of Common Stock that would then be issuable upon conversion in full of all then outstanding Debentures would exceed the Issuable Maximum, and (B) the Company shall not have previously obtained the Shareholder Approval, then, the Holder shall be entitled to require the Company to pay to it in cash an amount equal to the outstanding principal amount of the Debentures (plus all accrued and unpaid dividends thereon) then held by such Holder for which a potential conversion on such date would result in an issuance of shares of Common Stock in excess of such Holder's pro-rata portion (which shall be calculated pursuant to the terms hereof) of the Issuable Maximum. The outstanding principal amount of the Debentures shall be reduced by the Excess Principal Amount upon the Holder's receipt of the Excess Principal Amount pursuant to the terms hereof. The Company and the Holder understand and agree that shares of Common Stock issued to and then held by the Holder as a result of conversions of Debentures shall not be entitled to cast votes on any resolution to obtain Shareholder Approval pursuant hereto. (iv) Notwithstanding anything herein to the contrary, the Company may not issue, agree to issue, or enter into any arrangement pursuant to which it may issue at any time, shares of Common Stock or Common Stock Equivalents that would entitle any holder thereof to receive at any time shares of Common Stock at, in any such case, a price that is less than the Conversion Price, unless prior to the earlier to occur of the entering into of such agreement or such issuance, the Company obtains the approval of its shareholders pursuant to the rules and regulations of the Nasdaq Stock Market, Inc. ("NASDAQ") (including, without limitation, NASD Rules 4350(i), NASD IM-4300, NASD IM-4310-2, and Rule 4350(i)): for (i) the transactions contemplated by the Transaction Documents and the ZLP Purchase Agreement, including, without limitation, the sale, issuance and potential issuance of the securities issued and issuable thereunder, including the securities issued pursuant to the Purchase Agreement as well as the shares of Common Stock issuable in accordance with the Debentures, the Warrants and Adjustment Warrants, (ii) the issuance under the Transaction Documents and the ZLP Purchase Agreement (and transactions -13- contemplated thereby) of in excess of 19.99% of the shares of Common Stock outstanding prior to the Original Issuance Date at a price that is less than the greater of book or market value of the Common Stock, and/or (iii) the potential issuance of securities of the Company having sufficient voting power to result in a change of control of the Company as described under the rules of Nasdaq. The Company understands and agrees that the shares of Common Stock that have been issued or that may be issued to and then held by any Holder or any of such Holder's Affiliates may not cast votes on such matters. In the event that the Company enters into or seeks to enter into a transaction described in this Section 5(b)(iii), then the Company shall deposit into an escrow account with an escrow agent (which account and agent shall be reasonably satisfactory to the Holders) an amount equal to the aggregate outstanding principal amount of Debentures plus all accrued and unpaid interest thereon plus all liquidated damages and other amounts payable thereon, which amount shall be paid to the Holders in the event that the Company fails to obtain the approval of its stockholders with respect to such transaction. (c) MECHANICS OF CONVERSION. By the third Trading Day after each Conversion Date, the Company shall issue or cause to be issued and cause to be delivered to or upon the written order of the Holder and in such name or names as the Holder may designate a certificate for the Underlying Shares issuable upon such conversion which, unless required by the Purchase Agreement, shall be free of all restrictive legends. The Holder, or any Person so designated by the Holder to receive Underlying Shares, shall be deemed to have become the holder of record of such Underlying Shares as of the Conversion Date. If the Company's transfer agent is eligible to participate in the Depositary Trust Corporation DWAC system and no legends are required to be included on the certificates representing Underlying Shares pursuant to the Purchase Agreement, the Company shall, upon request of the Holder, use its best efforts to deliver Underlying Shares hereunder electronically through the Depository Trust Corporation or another established clearing corporation performing similar functions. (d) To effect conversions hereunder, the Holder shall not be required to physically surrender this Debenture unless the aggregate principal amount represented by such Debenture is being converted, in which event, the Holder shall deliver such Debenture promptly to the Company (it being understood that such delivery is not a condition precedent to the Company's obligations to deliver Underlying Shares upon such conversion). Conversions hereunder shall have the effect of lowering the outstanding principal amount represented by such Debenture in an amount equal to the applicable conversion, which shall be evidenced by entries set forth in the Conversion Schedule attached as SCHEDULE I, which will be maintained by the Company and the Holder. (e) The Company's obligations to issue and deliver Underlying Shares upon conversion of this Debenture in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of such Underlying Shares. -14- (f) If by the third Trading Day after a Conversion Date the Company fails to deliver to the Holder such Underlying Shares in such amounts and in the manner required pursuant to Section 5(a), then the Holder will have the right to rescind such conversion. (g) If by the third Trading Day after a Conversion Date the Company fails to deliver to the Holder such Underlying Shares in such amounts and in the manner required pursuant to Section 5(c), and if after such third Trading Day the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by such Holder of the Underlying Shares which the Holder anticipated receiving upon such conversion (a "BUY-IN"), then the Company shall: (A) pay in cash to the Holder (in addition to any remedies available to or elected by the Holder) the amount by which (x) the Holder's total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the aggregate number of Underlying Shares that the Company was required to deliver to the Holder in connection with the conversion at issue by (2) the Closing Price at the time of the obligation giving rise to such purchase obligation and (B) at the option of the Holder, either reinstate the principal amount of Debentures and equivalent number of Underlying Shares for which such conversion was not timely honored or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its conversion and delivery obligations hereunder. For example, if the Holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of Debentures with a market price on the date of conversion totaling $10,000, under clause (A) of the immediately preceding sentence, the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In. (h) ADJUSTMENTS TO CONVERSION PRICE. The Conversion Price in effect on any Conversion Date shall be subject to adjustments in accordance with this Section 5(h): (i) STOCK DIVIDENDS AND SPLITS. If the Company, at any time while any Debentures are outstanding, (i) pays a stock dividend on its shares of Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such case the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. (ii) ADDITIONAL DISTRIBUTIONS. If the Company, at any time while any Debentures are outstanding, shall distribute to all holders of shares of Common Stock (and not to Holders) evidences of its indebtedness or assets or rights or warrants to subscribe for or purchase any security, then in each such case the Conversion Price at which the principal amount of Debentures shall thereafter be convertible shall be determined by multiplying the Conversion -15- Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall be the Closing Price determined as of the record date mentioned above, and of which the numerator shall be such Closing Price on such record date less the then fair market value at such record date of the portion of such assets or evidence of indebtedness so distributed applicable to one outstanding Common Share as determined by the Board of Directors in good faith. In either case the adjustments shall be described in a statement provided to the Holders of the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above. (iii) SUBSEQUENT EQUITY SALES. If the Company or any subsidiary thereof, at any time while Debentures are outstanding and during the period between the Original Issue Date and the 18th month anniversary of the Effective Date (provided that such period shall be extended by the number of days in which the Registration Statement is not effective or the prospectus included in the Registration Statement may not be used by the selling stockholders thereunder for the resale of the shares of Common Stock registered thereunder), shall issue shares of Common Stock or Common Stock Equivalents entitling any Person to acquire shares of Common Stock, at a price per share less than the Conversion Price (if the holder of the Common Stock or Common Stock Equivalent so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights issued in connection with such issuance, be entitled to receive shares of Common Stock at a price less than the Conversion Price, such issuance shall be deemed to have occurred for less than the Conversion Price), then, at the option of the Holder for such exercises as it shall indicate, the Conversion Price shall be adjusted to equal the conversion, exchange or purchase price for such Common Stock or Common Stock Equivalents (including any reset provisions thereof) at issue. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued, and which adjusted Conversion Price shall continue for as long as the Debentures remain outstanding. The Company shall notify the Holder in writing, no later than the Trading Day following the issuance of any Common Stock or Common Stock Equivalent subject to this section, indicating therein the applicable issuance price, or of applicable reset price, exchange price, conversion price and other pricing terms. (A) If, at any time while any Debentures are outstanding, the Company or any subsidiary issues Common Stock Equivalents at a price per share that floats or resets or otherwise varies or is subject to adjustment based on market prices of the Common Stock (a "FLOATING PRICE SECURITY"), then for purposes of applying the preceding paragraph in connection with any subsequent exercise, the Conversion Price will be determined separately on each Conversion Date and will be deemed to equal the lowest price per share at which any holder of such Floating Price Security is entitled to acquire shares of Common Stock on such Conversion Date (regardless of whether any such Holder actually acquires any shares on such date). (B) Notwithstanding the foregoing, no adjustment will be made under this Section 5(h)(iii) as a result of: (i) any grant of an option or warrant for Common Stock or issuance of any shares of Common Stock upon the exercise of any options or warrants to employees, officers and directors of or -16- consultants to the Company pursuant to any stock option plan, employee stock purchase plan or similar plan or consulting arrangement approved by the Company's board of directors or (ii) any rights or agreements to purchase Common Stock or Common Stock Equivalents outstanding on the Original Issue Date hereof and as specified in SCHEDULE 3.1(G) (but not as to any amendments or other modifications to the number of shares of Common Stock issuable thereunder, the terms set forth therein, or the exercise price set forth therein) or (iii) the issuance of shares of Common Stock in connection with a Strategic Transaction or (iv) the issuance of up to 2,900,000 shares of Common Stock (as adjusted for stock splits, reverse stock splits, combinations and other similar transactions) to any Approved Purchaser (as defined in the Purchase Agreement) pursuant to Registration Statement No. 333-71086 or (v) the issuance of Common Stock pursuant to the Transaction Documents or the ZLP Purchase Agreement (or the transactions contemplated thereby). (iv) 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. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock. (v) NOTICE OF ADJUSTMENTS. Whenever the Conversion Price is adjusted pursuant to the terms hereof the Company shall promptly mail to each Holder, a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. (i) CERTAIN FUNDAMENTAL TRANSACTIONS. In case of any Fundamental Transaction, a Holder shall have the right to do any of the following: (1) convert its Debentures into the shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of shares of Common Stock following such Fundamental Transaction and such Holder shall be entitled upon such Fundamental Transaction to receive such amount of securities, cash and property as the shares of Common Stock into which such Debentures could have been converted immediately prior to such Fundamental Transaction would have been entitled, or (2)(x) require the surviving entity to issue debentures in such principal amount equal to the principal amount of the Debentures held by such Holder prior to such Fundamental Transaction, plus all other amounts owing thereon, which newly issued debentures shall have identical terms to the terms of the Debentures and shall be entitled to all of the rights and privileges of a Holder set forth herein and the agreements pursuant to which the prepayment was issued, and (y) simultaneously with the issuance of such convertible debentures shall have the right to convert such shares only into shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of shares of Common Stock following such Fundamental Transaction (the conversion price applicable for the newly issued convertible debentures shall be based upon the amount of securities, cash and property that each Common Share would receive in such Fundamental Transaction and the Conversion Price stated herein) or (3) at the Holder's option and request, any successor to the Company or surviving entity in such Fundamental Transaction shall either pay to the Holder the greater of (A) the outstanding principal amount of the Debentures held by such Holder plus all accrued and unpaid interest thereon, and (B) the principal amount of the Debenture held by such Holder, plus all accrued and unpaid interest thereon, divided by the Conversion Price on the Trading Day immediately preceding (x) the date of prior -17- to such Fundamental Transaction or (y) the date the amount set forth in this section is paid in full, whichever is less, multiplied by the Closing Price on (x) the date of the Fundamental Transaction or (y) the date the amount set forth in this section is paid in full, whichever is greater. Any Fundamental Transaction shall include such terms so as continue to give the Holders the right to receive the securities, cash and property set forth in this Section upon any conversion or redemption following such event. This provision shall similarly apply to successive such Fundamental Transactions. The rights set forth herein shall not alter the rights of a Holder set forth in Section 6, provided, that, a Holder may only exercise the rights set forth herein or the rights set forth in Section 6 with respect to a single event giving rise to such rights. (j) RECLASSIFICATIONS; SHARE EXCHANGES. In case of any reclassification of the shares of Common Stock, or any compulsory share exchange pursuant to which the shares of Common Stock are converted into other securities, cash or property (other than compulsory share exchanges which constitute a Sale Event), the Holders of the Debentures then outstanding shall have the right thereafter to convert such shares only into the shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of shares of Common Stock following such reclassification or share exchange, and the Holders shall be entitled upon such event to receive such amount of securities, cash or property as a holder of the number of shares of Common Stock of the Company into which such shares of Debentures could have been converted immediately prior to such reclassification or share exchange would have been entitled. This provision shall similarly apply to successive reclassifications or share exchanges. (k) NOTICE OF CORPORATE EVENTS. If: (a) the Company shall declare a dividend (or any other distribution) on the Common Stock, (b) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (c) the Company shall authorize the granting to all holders of Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (d) the approval of any stockholders of the Company shall be required in connection with any Sale Event or Fundamental Transaction, or (e) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company; then the Company shall file a press release or Current Report on Form 8-K to disclose such occurrence and notify the Holders at their last addresses as they shall appear upon the stock books of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which any such Sale Event or Fundamental Transaction is expected to become effective or close, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities, cash or other property deliverable upon any such Sale Event or Fundamental Transaction. Holders are entitled to convert the outstanding principal amount of the Debentures during the 20-day period commencing the date of such notice to the effective date of the event triggering such notice. (l) RESERVATION OF COMMON STOCK. The Company covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock solely for the purpose of issuance upon conversion of Debentures, each as herein provided, free from preemptive rights or any other -18- actual contingent purchase rights of persons other than the Holders, not less than such number of shares of Common Stock as shall be issuable upon the conversion of all outstanding principal amount of Debentures. The Company covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly and validly authorized and issued and fully paid and nonassessable. (m) FRACTIONAL SHARES. Upon a conversion hereunder the Company shall not be required to issue stock certificates representing fractions of shares of Common Stock, but may if otherwise permitted, make a cash payment in respect of any final fraction of a share based on the Closing Price on the applicable Conversion Date. If any fraction of an Underlying Share would, except for the provisions of this Section, be issuable upon a conversion hereunder, the Company shall pay an amount in cash equal to the Conversion Price multiplied by such fraction. (n) STAMP TAXES. The issuance of certificates for Common Stock on conversion of principal amount of this Debenture shall be made without charge to the Holders thereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificate, provided that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the Holder of such Debentures so converted. (o) NOTICES. Any and all notices or other communications or deliveries to be provided by the Holders, including, without limitation, any Holder Conversion Notice, shall be in writing and delivered personally, by facsimile or sent by a nationally recognized overnight courier service, addressed to the attention of the Chief Financial Officer of the Company addressed to Peregrine Pharmaceuticals, Inc., 14272 Franklin Avenue, Tustin, California 92780, Facsimile No.: (714) 838-5817, attention Chief Financial Officer, or to such other address or facsimile number as shall be specified in writing by the Company for such purpose.

Any notice or other communication or deliveries hereunder shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile telephone number specified in this Section prior to 6:30 p.m. (New York City time) (with confirmation of transmission), (ii) the date after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile telephone number specified in this Section later than 6:30 p.m. (New York City time) on any date and earlier than 11:59 p.m. (New York City time) on such date (with confirmation of transmission), (iii) upon receipt, if sent by a nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given. 6. RESTRICTED ACTIONS. Neither the Company nor any subsidiary shall taken any Restricted Action without the prior written consent of the Required Holders. -19- 7. PREPAYMENTS. (a) UPON EVENT OF DEFAULT. Upon the occurrence of an Event of Default, each Holder shall (in addition to all other rights it may have hereunder or under applicable law), have the right, exercisable at the sole option of such Holder, and by delivery of a written notice to the Company to require the Company (an "EVENT OF DEFAULT NOTICE") to prepay all or a portion of the Debentures then held by such Holder and, at the option of the Holder, all or a portion of the Reinstated Principal, for an amount, in cash, equal to the Mandatory Prepayment Amount. The Mandatory Prepayment Amount shall be due and payable within five Trading Days of the date of the Event of Default Notice. For purposes of this Section, principal amount of Debentures shall remain outstanding until such date as the Holder shall have received Underlying Shares upon a conversion (or attempted conversion) thereof that meets the requirements hereof. Notwithstanding anything herein to the contrary, upon the occurrence of a Bankruptcy Event, all outstanding principal and accrued but unpaid interest on this Debenture shall immediately become due and payable in full in cash, without any further action by the Holder, and the Company shall immediately be obligated to pay the Mandatory Prepayment Amount pursuant to this paragraph as if the Holder had delivered a Event of Default Notice immediately prior to the occurrence of any such Event of Default. The Holder need not provide and the Company hereby waives any presentment, demand, protest or other notice of any kind, and the Holder may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such declaration may be rescinded and annulled by Holder at any time prior to payment hereunder. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon. (b) UPON SALE EVENT. The Company shall notify the Holders on the day that the Company enters into a transaction giving rise to a Sale Event (such notice, a "COMPANY REDEMPTION NOTICE" and the date such Company Redemption Notice is received by a Holder, a "COMPANY REDEMPTION DATE"). The Company Redemption Notice shall describe the Sale Event and state the consideration being paid in such Sale Event and the date of consummation of the Sale Event. In addition, on the day that the Company delivers to the Holders a Company Redemption Notice, the Company shall also issue a press release and file a Current Report on Form 8-K, in each case disclosing all material terms of the Sale Event. Concurrent with the closing of the Sale Event (and as a condition precedent to such closing), the Company shall, redeem, in cash, all outstanding principal amount of the Debentures which have not previously been redeemed or for which Conversion Notices shall not have been delivered, at a price equal to the Company Redemption Price. Notwithstanding the foregoing, a Holder may convert (and the Company shall honor such conversions in accordance with the terms hereof) any or all of the outstanding principal amounts of Debentures subject to a Company Redemption Notice delivered for conversion on or prior to the Sale Event. Concurrent with the closing of the Sale Event, the Company shall cause the escrow agent holding the Company Redemption Price to pay to the Holders the Company Redemption Price, which amount shall be due and payable in cash, and such payment of the Company Redemption Amount shall be a condition precedent to the closing of the Sale Event. (c) AT COMPANY'S OPTION. If after the Effective Date, the Closing Price for ten consecutive Trading Days is less than $1.00 per share (as -20- adjusted for stock splits, stock dividends, stock combinations and other similar transactions) (the "MINIMUM PRICE"), then the Company may deliver a notice to the Holders (an "OPTIONAL REPAYMENT NOTICE" and the date such notice is received by the Holders, the "OPTIONAL REPAYMENT NOTICE DATE") of its irrevocable election to repay all, but not less than all, of the then aggregate amount of outstanding Debentures, for an amount, in cash, equal to the Company Redemption Price. The Company Redemption Amount payable pursuant to this Section 7(c) is due in full on the tenth Trading Day following the Optional Repayment Notice Date. The Company may only deliver an Optional Repayment Notice if from the first of the ten Trading Days utilized to determine whether the Minimum Price has been so met through and including the tenth Trading Day following the Optional Repayment Notice Date each of the following shall be true: (i) the Closing Price shall be less than the Minimum Price, (ii) the Company shall have duly honored all conversions and redemptions scheduled to occur or occurring by virtue of one or more Conversion Notices prior to the Optional Repayment Due Date, (iii) the Equity Conditions shall have been satisfied at all times. If any of the foregoing conditions shall cease to be satisfied at any time during the required period, or if the Company shall fail to pay the Optional Repayment Amount in full by the Optional Repayment Due Date, then the Optional Repayment Notice shall be null and void, ab initio, and the Company may not deliver any subsequent Optional Repayment Notices. The Holder may convert any portion of this Debenture prior to the Optional Repayment Due Date. The Company covenants and agrees that it will honor all Conversion Notices tendered from the time of delivery of the Optional Repayment Notice through the Optional Repayment Due Date. 8. RANKING. This Debenture ranks pari passu to all other Debentures now or hereafter issued pursuant to the Transaction Documents. No Indebtedness of the Company is senior to this Debenture in right of payment, whether with respect of interest, damages or upon Liquidation or dissolution or otherwise. 9. SECURED OBLIGATION. The payment obligations under this Debenture are secured pursuant to the Security Agreement and Intellectual Property Security Agreement. Such agreements will terminate upon the earlier to occur of the following: (i) with respect to the Holder upon the date on which all payments hereunder have been made in full or the Debenture has otherwise been converted pursuant to the terms hereof and (ii) the 21st day following (but not including) the date that the Closing Price exceeds $1.25 per share (as adjusted for stock splits, stock dividends, stock combinations and other similar transactions) for 20 consecutive Trading Days and the Equity Conditions shall have been satisfied at all times during such 20 consecutive Trading Days. 10. MISCELLANEOUS. (a) This Debenture shall be binding on and inure to the benefit of the parties hereto and their respective successors and assigns. This Debenture may be amended only in writing signed by the Company and the Holder and their successors and assigns. -21- (b) Subject to Section 9(a), above, nothing in this Debenture shall be construed to give to any person or corporation other than the Company and the Holder any legal or equitable right, remedy or cause under this Debenture. This Debenture shall inure to the sole and exclusive benefit of the Company and the Holder.

Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal Proceeding. If either party shall commence a Proceeding, then the prevailing party in such Proceeding shall be reimbursed by the other party for its attorney's fees and other costs and expenses incurred with the investigation, preparation and prosecution of such Proceeding. (d) The headings herein are for convenience only, do not constitute a part of this Debenture and shall not be deemed to limit or affect any of the provisions hereof. (e) In case any one or more of the provisions of this Debenture shall be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Debenture shall not in any way be affected or impaired thereby and the parties will attempt in good faith to agree upon a valid and enforceable provision which shall be a commercially reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Debenture. (f) No provision of this Debenture may be waived or amended except in a written instrument signed, in the case of an amendment, by the Company and the Holder or, or, in the case of a waiver, by the Holder. No waiver of any default with respect to any provision, condition or requirement of this Debenture shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right. (g) Any cash amounts due from the Company under this Debenture, including, interest, liquidated damages and redemption amounts, which is not paid on the date such payment is due to be paid shall continue to accrue and shall entail a late fee, which must be paid in cash, at the rate of 15% per annum or the lesser rate permitted by applicable law (such fees to accrue daily, from the date such amount is due hereunder through and including the date of payment in full of such amount). -22- (h) If it shall be found that any interest due hereunder shall violate applicable laws governing usury, the applicable rate of interest due hereunder shall be reduced to the maximum permitted rate of interest under such law. (i) Except pursuant to the terms of this Debenture, the outstanding principal amount and interest under this Debenture may not be prepaid by the Company without the prior written consent of the Holder.
