Subject to the payment in full of all Senior Indebtedness, the Noteholders (together and pro rata with the holders of any other indebtedness of the Company which is subordinate in right of payment to the payment of other indebtedness of the Company, but is not subordinate in right of payment to the Notes and by its terms grants the right of subrogation to the holders thereof) shall be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions of assets of the Company made on the Senior Indebtedness until the principal of and interest on the Notes shall be paid in full; and, for the purposes of such subrogation, no payments or distributions to the holders of Senior Indebtedness of any cash, property, or securities to which the Noteholders would be entitled except for these provisions shall, as between the Company, its creditors other than the holders of Senior Indebtedness, and the Noteholders, be deemed to be a payment by the Company to or on account of Senior Indebtedness, it being understood that these provisions are and are intended solely for the purpose of defining the relative rights of the Noteholders, on the one hand, and the holders of Senior Indebtedness, on the other hand. 9.7 OBLIGATIONS UNIMPAIRED. Nothing contained in this Section 9 is intended to or shall impair as between the Company, its creditors other than the holders of Senior Indebtedness and the Noteholders, the obligation of the Company, which shall be absolute and unconditional, to pay to the Noteholders the principal of and interest on the Notes as and when the same shall become due and payable in accordance with the terms thereof, or is intended to or shall affect the relative rights against the Company of the Noteholders and creditors of the Company other than the holders of Senior Indebtedness, nor shall anything herein or therein prevent the Noteholder from exercising all remedies otherwise permitted by applicable law upon default, subject to the rights, if any, under this 8 Section 9 of the holders of Senior Indebtedness in respect of any required notice of the exercise of any such remedy or cash, property, or securities of the Company otherwise payable or deliverable to such holder. Each Noteholder by his acceptance thereof shall be deemed to acknowledge and agree that the subordination provisions of this Section 9 are, and are intended to be, an inducement and a consideration to each holder of any Senior Indebtedness, whether such Senior Indebtedness, was created or acquired before or after the issuance of the Notes, to acquire and continue to hold, or to continue to hold, such Senior Indebtedness and each holder of Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Indebtedness. 10. SUBSTITUTION OF NOTES. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction, or mutilation of any Note, and of indemnity satisfactory to it (which, in the case of any original purchaser of the Notes, shall be a contractual obligation of such purchaser) and upon surrender, at the office or agency maintained in accordance with Section 8 hereof, and cancellation of any Note, if mutilated, the Company will execute and deliver a new Note of like tenor, in lieu of such Note, dated the most recent date to which interest on such Note shall have been paid. 11. EVENTS OF DEFAULT. 11.1 DEFINITION; REMEDIES. If any one or more of the following events (herein called "Events of Default") shall occur and be continuing: (a) default shall be made in the payment of principal of any of the Notes when and as the same shall become due and payable, either at maturity or by acceleration or otherwise; (b) default shall be made in the payment of interest on the Notes when the same becomes due and payable; (c) default shall be made in the due performance or observance of any other covenant, agreement, or provision herein to be performed or observed by the Company or a material breach shall exist in any representation or warranty herein contained, and such default or material breach shall have continued for a period of 30 days after written notice thereof to the Company from the Agent or from any holder or holders of Notes aggregating not less than 51% of the aggregate principal amount of the Notes then outstanding; provided, however, that if any such default or material breach shall be such that it cannot be cured or corrected within such 30-day period, such period shall be extended for such additional period of time (not exceeding 30 additional days) as shall be necessary to effect such cure or correction if curative or corrective action is instituted within said 30-day period and thereafter diligently pursued; or (d) the Company shall (i) apply for or consent to the appointment of a receiver, trustee, or liquidator of the Company or any of its assets, (ii) make a general assignment for the benefit of creditors, (iii) be adjudicated a bankrupt or insolvent or (iv) file a voluntary petition in bankruptcy, or a petition or answer seeking reorganization or an arrangement with creditors to take advantage of any bankruptcy, reorganization, insolvency, readjustment of debt, moratorium, dissolution, liquidation, or debtor relief law, or any chapter of any such law, or an answer admitting the material allegations of a petition filed against it in any proceeding under any such law or chapter, or corporate action shall be taken by the Company for the purpose of effecting any of the foregoing; (v) or an order, judgment, or decree shall be entered, without the application, approval, or consent of the Company, by any court of competent jurisdiction, approving a petition seeking liquidation or reorganization of the Company of all or a substantial part of the assets of the Company, and provided that such order, judgment, or decree remains in effect for more than 60 consecutive days; (e) a Senior Indebtedness Default shall occur and continue for a period of 30 days; (f) default shall occur with respect to any other indebtedness for borrowed money of the Company (other than the Notes or Senior Indebtedness) or under any agreement under which indebtedness may be issued by the Company and such default shall continue for more than the period of grace, if any, therein specified, if the aggregate amount of such indebtedness for which such default shall have occurred exceeds $300,000; (g) default shall occur with respect to any contractual obligation of the Company under or pursuant to any contract, lease, or other agreement to which the Company is a party and such default shall 9 continue for more than the period of grace, if any, therein specified, if the aggregate amount of the Company's contractual liability arising out of such default exceeds or is reasonably estimated to exceed $300,000; (h) final judgment for the payment of money in excess of $300,000 shall be rendered against the Company and the same shall remain undischarged for a period of 30 days during which execution shall not be effectively stayed; (i) default shall occur if (A) the Company's Net Revenues for the twelve months ending March 30, 2004 is less than $15 million, which shall be calculated upon the filing of the Company's Form 10-Q for the quarter ending June 30, 2004, or (B) the Company fails to file its Form 10-Q for the quarter ending June 30, 2004 within 50 days from June 30, 2004; or (j) upon a Change of Control; then and in each and every such case the Agent (upon the written authorization of the holders of Notes aggregating not less than 51% of the aggregate principal amount of the Notes then outstanding) may by notice in writing to the Company declare the unpaid principal of all the Notes together with accrued interest thereon to be forthwith due and payable and thereupon such principal and interest shall be due and payable without presentment, protest, or further demand or notice of any kind, all of which are hereby expressly waived. This Section 11, however, is subject to the condition that, if at any time after the occurrence of an Event of Default hereunder, and before the entry of any judgment or decree against the Company for the payment of all or any portion of the Notes then outstanding, the Noteholders aggregating not less than 51% of the aggregate principal amount of the Notes then outstanding (acting either by and through the Agent or otherwise) may, by written notice to the Company, either temporarily suspend or permanently rescind and annul such declaration of an Event of Default and its consequences (including, without limitation, the acceleration of the Notes as a result of such Event of Default); but no such suspension or rescission and annulment shall extend to or affect any prior, concurrent, or subsequent default or Event of Default (other than the ones identified by the Noteholders declaring them due as the ones upon which such declaration was based) or impair any right consequent thereon. Notwithstanding anything to the contrary herein, if default shall be made in the payment of any principal of, or interest on, any Note when and as the same shall become due and payable, at maturity (but not merely by virtue of an acceleration pursuant to the foregoing provisions of this Section 11.1), the Noteholder may by notice in writing to the Company declare the unpaid principal of such Note, with accrued interest, to be forthwith due and payable and thereupon such principal and interest shall be due and payable without presentment, protest, or further demand or notice of any kind, all of which are hereby expressly waived. If any Noteholder shall demand payment thereof or take any other action (of which the Company has actual knowledge) in respect of a default occurring in the payment of any principal of, or interest on, any Note when and as the same shall become due and payable, the Company will forthwith give written notice thereof to the Agent, who will in turn give written notice of the same to each holder of record of the Notes then outstanding. 11.2 APPOINTMENT OF AGENT FOR NOTEHOLDERS. The Noteholders hereby appoint the Agent as the Noteholders' agent and representative hereunder, with full right of substitution, to act for and on behalf of the Noteholders, until removed pursuant to Section 13.8 hereof. Except as otherwise expressly provided in this Agreement, the Agent is hereby granted the right, power and authority, and is hereby instructed by the Noteholders, to do on behalf of the Noteholders all things which, in the Agent's judgment, are necessary, proper or desirable to carry out the responsibilities of exercising the remedies herein afforded to the Noteholders, including but not limited to the right, power and authority from time to time to do the following: (i) communicate on behalf of the Noteholders with the Company with respect to the subject matter of this Agreement, (ii) provide the Noteholders with copies of any and all communications or notices sent or received under this Agreement or otherwise pertaining to the subject matter hereof, (iii) if and as required, exercise, in the name and on behalf of the Noteholders, the remedies provided for in this Agreement, and (iv) take such other actions as the Noteholders, by majority vote of the holders of Notes aggregating not less than 51% of the aggregate principal amount of the Notes then outstanding, may direct in writing. 11.3. NO AUTHORITY TO AMEND. Without the unanimous written consent of the Noteholders, the Agent shall not have the authority to amend, modify, or waive the terms of this Agreement, or to consent to any action or failure to act, the effect of which would (i) postpone the date fixed for repayment of the Notes, or interest thereon, to 10 Noteholders, (ii) reduce the amount of interest on any amounts payable to the Noteholders hereunder, or (iii) subject the Noteholders to any additional obligations. The Agent hereby agrees, however, to execute and join in any amendment, modification or waiver of any of the terms of this Agreement approved either under the provisions of this Section 11.3 or those of Section 16 hereof. 11.4. REMEDIES NOT EXCLUSIVE. No right or remedy by the terms of this Agreement conferred upon or reserved to the Agent (or to the Noteholders) is intended to be exclusive of any other right or remedy, but each and every such right or remedy shall be cumulative and shall be in addition to any other right or remedy given hereunder or now or hereafter existing at law or in equity or by statute. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 11.5. DIRECTING TIME, METHOD AND PLACE OF REMEDY. The holders of not less than 51% in aggregate principal amount of the Notes may in writing direct the time, method and place of conducting any proceeding for any remedy available to the Agent, or for exercising any power conferred upon the Agent under this Agreement, provided that such direction shall not be otherwise than in accordance with the provisions of law and of this Agreement, and the Agent may take any other action deemed proper by the Agent which is not inconsistent with such direction. 11.6. POSSESSION OF NOTES NOT REQUIRED. All right of action (including the right to file and prove claims) and claims under this Agreement or under any of the Notes may be prosecuted and enforced by the Agent without the possession of any of the Notes or the production thereof in any suit or proceeding relating thereto; and any such suit or proceeding instituted by the Agent shall be brought in its name as Agent for the Noteholders, and any recovery of judgment shall, after provision for the payment of all amounts payable to the Agent pursuant to Section 13.7 hereof, be for the equal benefit of the holders of the outstanding Notes in respect of which such judgment has been recovered. 11.7. PRIOR NOTIFICATION TO AGENT. Except as specifically provided in Section 11.1 hereof, no holder of any Note shall have any right to cause an acceleration of the maturity of the Notes, or institute any suit, action or proceeding in equity or at law with respect to this Agreement, or for the appointment of a receiver or any other remedy hereunder, unless such holder shall have previously given to the Agent written notice of a continuing Event of Default, and unless (i) the holders of not less than 51% in aggregate principal amount of the Notes shall have made written request to the Agent to institute such action, suit or proceeding in its own name as Agent hereunder, and the Agent shall have declined to take such action or shall have failed to do so within 30 days thereafter and (ii) no annulment of such Event of Default and its consequences pursuant to Section 11.1 hereof (or other direction inconsistent with such request) shall have been given to the Agent during such 30-day period by the holders of not less than 51% in aggregate principal amount of the outstanding Notes, it being understood and intended that no one or more Noteholders shall have any right in any manner whatsoever by his or their action to enforce any right hereunder except in the manner herein provided, and that all proceedings at law or in equity shall be instituted, had and maintained in the manner herein provided and for the ratable and equal benefit of all holders of outstanding Notes. Notwithstanding any other provision of this Agreement, the right of any holder of any Note to receive payment of the principal of and interest on such Note on or after the respective due dates expressed in such Notes, and to institute suit for enforcement of any such payment on or after such respective dates in accordance with the provisions hereof and to institute suit therefor, shall not be impaired or affected without the consent of such holder. Further, nothing in this Section 11.7 shall be construed as impairing the right of any holder or holders of Notes aggregating not less than 51% of the aggregate principal amount of the Notes then outstanding to give the notice of default to the Company as specified in Section 11.1(c) hereof upon or after the occurrence of an event described therein. 11.8. NOTIFICATION OF EVENT OF DEFAULT. The Agent shall, within 30 days after the occurrence of an Event of Default, give to the Noteholders written notice of all Events of Default known to the Agent, unless such default(s) shall have been cured or waived before the giving of such notice. The Agent shall likewise give to the Noteholders written notice of all written communications given by the Agent to, or received by the Agent from, the Company. 11.9. COSTS OF COLLECTION. The Company covenants that, if default be made in any payment of principal of or interest on any Note, it will pay to the holder thereof such further amount as shall be reasonably sufficient to cover the cost and expense of collection, including, without limitation, court costs and reasonable compensation to the attorneys and counsel of the holder for all services rendered in that connection. 11 11.10. NO COURSE OF DEALING. No course of dealing between the Company and any Noteholder or any delay on the part of the Noteholder in exercising any rights thereunder or hereunder shall operate as a waiver of any rights of any such holder. 12. REPRESENTATIONS OF PURCHASER. Each Purchaser represents and warrants to the Company as of the date hereof, as follows: 12.1. INVESTMENT REPRESENTATIONS. The Purchaser is acquiring the Notes for investment purposes and not with a view to the resale or distribution of all or any part thereof. The Purchaser acknowledges that the Notes have not been registered under the Securities Act, or the securities or "blue sky" laws of any state or other domestic or foreign jurisdiction, and that none of such securities may be sold, transferred or otherwise disposed of except pursuant to an effective registration statement thereunder or an applicable exemption therefrom. 12.2. AUTHORITY. The execution and delivery of this Agreement, and the consummation of the transactions contemplated hereby by the Purchaser has been duly and validly authorized by all requisite action on the part of the Purchaser. This Agreement has been duly executed and delivered by the Purchaser and constitutes the valid and binding obligations of Purchaser, enforceable against the Purchaser in accordance with its terms except as the same may be limited by equitable principles and by bankruptcy, insolvency, moratorium and other laws of general application affecting the enforcement of creditors' rights. 12.3 ACCREDITED INVESTOR. Each Purchaser (i) has such knowledge and experience in financial and business matters that such Purchaser is capable of evaluating the merits and risks of his or her investment in the Notes and has the financial ability to assume the monetary risk associated therewith; (ii) is able to bear the complete loss of his or her investment in the Notes; has received such documents and information from the Company as such Purchaser has requested and has had the opportunity to ask questions of and receive answers from the Company and the terms and conditions of the offering of the notes and to obtain additional information ; (iv) is an "accredited investor" as defined in Rule 501(a) of Regulation D promulgated under the Securities Act; and (v) is not relying upon any statements or instruments made or issued by any person other than the Company in making a decision to invest in the Notes. 12.4. RESTRICTIVE LEGENDS. Each Note shall (unless otherwise permitted by the provisions of Section 12.5 hereof) and certificate for Common Stock issued upon conversion of a Note and each certificate for Common Stock issued to a subsequent transferee shall be stamped or otherwise imprinted with a legend in substantially the following form: "The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended ("Securities Act") or any state securities act. The securities have been acquired for investment and may not be sold, transferred, pledged or hypothecated unless (i) they shall have been registered under the Securities Act and any applicable state securities act, or (ii) the corporation shall have been furnished with an opinion of counsel, satisfactory to counsel for the corporation, that registration is not required under any such act." 12.5. NOTICE OF PROPOSED TRANSFERS. (a) Except as otherwise provided in paragraph (b) of this Section 12.4, prior to any transfer or attempted transfer of any Note or shares of Common Stock, the holder thereof shall give written notice to the Company of such holder's intention to effect such transfer. Each such notice shall describe the manner and circumstances of the proposed transfer and shall be accompanied by an opinion of counsel for such holder satisfactory to the Company, to the effect that such transfer may be effected without registration of such Note under the Securities Act. If such notice is accompanied by such an opinion, such holder shall be entitled to transfer such Note in conformity with the terms of such notice, and, if the opinion of counsel so specifies, the Note issued upon any such transfer shall not bear the restrictive legend set forth in Section 12.4. Such holder shall indemnify the Company for any transfer effected pursuant to this Section 12.5(a). (b) The procedure set forth in paragraph (a) of this Section 12.4 shall not apply to any transfer by you (or a transferee pursuant to this paragraph (b)) of any Note to any of your Subsidiaries or Affiliates; provided, however, that at the time of such transfer the transferee shall execute and deliver to the Company an "investment letter" containing substantially the representations provided in Sections 12.1, 12.2 and 12.3 hereof with respect to the Notes that are the subject of such transfer and its agreement to be bound by the provisions of this Section 12 and such transfer is otherwise exempt from registration under the securities Act and applicable state securities laws. Notes issued upon such transfer shall bear the appropriate restrictive legend set forth in Section 12.4 hereof. 12 12.6 TRANSFER OF YOUR RIGHTS. Your rights under this Section 12 shall inure to the benefit of all Persons who shall at any time be the holders of Notes originally purchased by you hereunder, pro rata in accordance with their respective interests, and each such holder, by such holder's acceptance of such Note, as the case may be, agrees to be and shall be deemed to be bound by all of your covenants set forth in this Section 12, to the extent that such covenants are applicable to such holder's Notes. 13. AGENT FOR NOTEHOLDERS. 13.1. ACCEPTANCE BY AGENT. The Agent hereby accepts the agency hereby created. The Agent undertakes, prior to an Event of Default, and after the curing or waiving of all Events of Default which may have occurred, to perform such duties and only such duties as are specifically set forth in this Agreement, and no implied covenants or obligations shall be read into this Agreement against the Agent. In case of an Event of Default (which has not been cured or waived) the Agent undertakes to exercise such of the rights and powers vested in it by this Agreement and to use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. 13.2. PROVISIONS GOVERNING AGENT'S ACTIONS. In the absence of bad faith on the part of the Agent: (a) the Agent may conclusively rely as to the truth of the statement and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Agent and conforming to the requirements of this Agreement; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Agent, the Agent shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Agreement; (b) the Agent shall not be personally liable for any error of judgment made in good faith by a responsible officer of the Agent unless it shall be proved that the Agent was grossly negligent in ascertaining the pertinent facts or otherwise acted in a grossly negligent manner or in bad faith; (c) the Agent shall not be personally liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of not less than 51% in aggregate principal amount of Notes at the time outstanding relating to the time, method, and place of conducting any proceeding for any remedy available to the Agent, or exercising any trust or power conferred upon the Agent under this Agreement; and (d) the Agent may consult with counsel, and a written opinion of counsel shall be full and complete authorization and protection in respect of any action taken or suffered by it hereunder in good faith and in accordance with such opinion of counsel. 13.3. FULL POWER TO GIVE NOTICES. Whenever it is provided in this Agreement that the Agent shall taken any action upon the happening of a specified event or upon the fulfillment of any condition or upon the request of the Company or of Noteholders, the Agent shall have full power to give any and all notices and to do any and all acts and things incidental to such action. 13.4. NO PERSONAL LIABILITY OF AGENT. None of the provisions of this Agreement shall require the Agent to advance or expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of the rights or powers herein conferred if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against risk or liability is not reasonably assured to it. 13.5. AGENT AS NOTEHOLDER. The Agent, in its individual or any other capacity, may become the owner or holder of Notes and may otherwise deal with the Company with the same rights it would have if it were not Agent. 13.6. MONEYS HELD BY AGENT IN TRUST. All moneys received by the Agent other than as compensation or reimbursement for the Agent's services hereunder, shall, until used or applied as herein provided, be held in trust for the purposes for which they were paid, but need not be segregated from other funds except as to the extent required by law. 13.7. COMPENSATION TO AGENT. The Company covenants and agrees to pay to the Agent from time-to-time, and the Agent shall be entitled to receive, reasonable compensation for all services rendered by the Agent in the exercise and performance of any of its powers and duties hereunder. The liability of the Company with 13 respect to the foregoing covenant shall survive the satisfaction and discharge of the Notes. If default is made in such payment by the Company, the Agent shall have a lien therefor prior to the Note on all property or funds held or collected by the Agent, as such, except funds held in trust for the benefit of the Noteholders. 13.8. REMOVAL OF AGENT. The Agent may be removed at any time by the holders of at least 51% in aggregate principal amount of the Notes then outstanding by filing with the Agent so removed and with the Company written evidence provided of such action in that regard taken by such percentage of the Noteholders. 13.9. RESIGNATION OF AGENT; APPOINTMENT OF SUCCESSOR AGENT. In case at any time the Agent (a) shall resign or shall be removed or (b) shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Agent or of its property shall be appointed, or any public officer shall take charge or control of the Agent or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then a vacancy shall be deemed to exist in the office of the Agent and a successor Agent may be appointed by the holders of at least 51% in aggregate principal amount of the Notes then outstanding by the filing with the successor Agent, the Company and the retiring Agent of written evidence of the action in that regard taken by such percentage of the Noteholders; provided that unless a successor Agent shall have been appointed by the Noteholders as aforesaid, the Company by instrument executed by order of its Board of Directors may appoint a temporary successor Agent to fill such vacancy. If no successor Agent shall have been appointed pursuant to the foregoing provisions of this Section 13.9 or shall have accepted appointment within three months after a vacancy shall have occurred in the office of Agent, the holder of any Note then outstanding or the retiring Agent may apply to any court of competent jurisdiction to appoint a successor Agent. The court to which a Noteholder applies to have a successor Agent appointed, may appoint a successor Agent as it deems proper. Any appointment of a successor Agent pursuant to this Section 13.9 shall become effective upon acceptance of appointment by the successor Agent. Any successor Agent appointed hereunder shall execute, acknowledge and deliver to its predecessor Agent, and also to the Company, an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Agent shall become effective and such successor Agent, without any further act, deed or conveyance, shall become fully vested with all the properties, rights, powers, trusts, duties and obligations of its predecessor hereunder, with like effect as if originally named as Agent herein; but the Agent ceasing to act shall nevertheless, on the written request of the Company or of the successor Agent, or of the holders of at least 10% in aggregate principal amount of the Notes then outstanding, execute, acknowledge and deliver such instruments and so such other things as may reasonably be required for more fully and certainly vesting and confirming in such successor Agent all such rights, powers, trusts, duties and obligations of the predecessor Agent, and the Agent ceasing to act shall also, upon like request, pay over, assign and deliver to the successor Agent any money or other property which may then be in its possession as Agent. Should any instrument from the Company be required by the new Agent for more fully and certainly vesting in and confirming to such new Agent such properties, rights, powers, trusts, duties and obligations, any and all such instruments shall, on request, be executed, acknowledged and delivered by the Company. Upon acceptance of appointment by a successor Agent as provided in this Section 13.9, the Company shall mail notice by first class mail postage prepaid of the succession of such Agent hereunder to the holders of all Notes at their addresses as they shall appear on the registry books of the Company maintained pursuant to this Agreement. If the Company shall fail to mail such notice within 10 days after acceptance of appointment by the successor Agent, the successor Agent shall cause such notice to be mailed at the expense of the Company. 13.10. SUCCESSOR TO AGENT BY MERGER. Any corporation into which the Agent may be merged or converted or with which it may be consolidated or any corporation resulting from any merger, conversion or consolidation to which the Agent shall be a party or any corporation succeeding to all or substantially all of the business of the Agent, shall be successor Agent under this Agreement, without the execution or filing of any paper or the performance of any further act on the part of any of the parties hereto. 13.11. AGENT NOT RESPONSIBLE FOR RECITALS. The recitals of fact contained herein shall be taken as the statement of the Company and the Agent assumes no responsibility for the correctness of the same. The Agent makes no representations as to the validity of this Agreement or of the Notes. 13.12. RELEASE OF AGENT BY NOTEHOLDERS. Each Noteholder hereby releases and discharges the Agent from any loss, liability, damages, costs and expenses (including, without limitation, attorneys' fees and expenses) incurred or suffered at any time during the term of this Agreement by such Noteholder, as a result of any action taken or omitted from being taken by the Agent in connection with this Agreement; provided, however, that such 14 Noteholder shall not be deemed to have released or discharged the Agent under this Section 13.12 for any loss, liability, damages, costs or expenses resulting from or attributable to gross negligence or willful misconduct on the part of the Agent. 13.13. INDEMNIFICATION OF AGENT BY THE COMPANY. The Company hereby agrees to indemnify and hold harmless the Agent, from and against any and all losses, liabilities (including liabilities for penalties), actions, suits, judgments, demands, damages, costs and expenses (including, without limitation, attorneys' fees and expenses) incurred or suffered by the Agent, as a result of any action taken or omitted from being taken by the Agent in connection with this Agreement or otherwise incurred or suffered by, made upon, or assessed against the Agent; provided, however, that the Company shall not be required to indemnify and hold harmless the Agent against any such losses, liabilities (including liabilities for penalties), actions, suits, judgments, demands, damages, costs or expenses resulting from or attributable to gross negligence or willful misconduct on the part of the Agent. The Company's obligations under this Section 13.13 shall survive the termination of this Agreement and the repayment of the Notes. 14. CONVERSION OF NOTES. 14.1. CONVERSION PRIVILEGE AND CONVERSION PRICE. At any time from the Final Closing Date until maturity, provided that the Note is then outstanding, the Noteholder may, at his option, convert any or all such indebtedness, principal and accrued interest, on the terms and conditions set forth in this Section 14, into fully paid and non-assessable shares of Common Stock. The number of shares of Common Stock which shall be issued upon conversion of a Note shall be determined by dividing the outstanding indebtedness on such Note (plus accrued interest thereon) by the Conversion Price (as defined herein) in effect at the time of conversion. The "Conversion Price" per share at which shares of Common Stock shall initially be issuable upon conversion of the indebtedness shall be the lesser of (a) the average closing price of the Common Stock for the thirty (30) trading days prior to the Initial Closing Date, (b) the average closing price of the Common Stock for the thirty (30) trading days prior to the Final Closing Date, and (c) $0.16 per share; provided however, that the Conversion Price shall be subject to adjustment pursuant to Section 14.4. 14.2. EXERCISE OF CONVERSION PRIVILEGE. To exercise the conversion privilege, the Noteholder shall give written notice to the Company stating that the Noteholder irrevocably elects to convert such indebtedness. Conversion shall be deemed to have been effected on the date when such delivery is made, and such date is referred to herein as the "Conversion Date." As promptly as practicable on or after the conversion date, the Company shall issue and shall deliver at such office or agency a certificate or certificates for the number of full shares of Common Stock issuable upon conversion, together with payment in lieu of any fraction of a share, as provided in Section 14.3. In the case of any Note that is converted in part only, upon such conversion the Company shall execute and the Company shall deliver to the holder thereof, at the expense of the Company, a new Note or Notes of authorized denominations in principal amount equal to the unconverted portion of such Note. No payment or adjustment shall be made upon any conversion on account of any interest accrued on the Notes surrendered for conversion after such surrender or on account of any dividends on the Common Stock issued upon conversion. Notes shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Notes for conversion in accordance with the foregoing provisions, and at such time the rights of the holders of such Notes as holders shall cease, and the Person or Persons entitled to receive the shares of Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock at such time. 14.3. FRACTIONAL SHARES. No fractional shares of Common Stock shall be issued upon conversion of Notes. If more than one Note shall be surrendered for conversion at one time by the same holder, the number of full shares which shall be delivered upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock that would otherwise be delivered upon conversion of any Note or Notes (or specified Portions thereof), the Company shall pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the market price per share of Common Stock (as deemed by the Board of Directors or in any manner prescribed by the Board of Directors) at the close of business on the day of conversion. 15 14.4 Adjustment of Conversion Price. (a) THE CONVERSION PRICE SHALL BE SUBJECT TO ADJUSTMENT AS FOLLOWS: (i) IF THE COMPANY, AT ANY TIME WHILE ANY NOTES ARE OUTSTANDING, (a) SHALL PAY A CASH DIVIDEND OR OTHERWISE MAKE A DISTRIBUTION OR DISTRIBUTIONS ON SHARES OF ITS COMMON STOCK PAYABLE IN SHARES OF COMMON STOCK, (b) SUBDIVIDE OUTSTANDING SHARES OF COMMON STOCK INTO A LARGER NUMBER OF SHARES, (c) COMBINE OUTSTANDING SHARES OF COMMON STOCK INTO A SMALLER NUMBER OF SHARES, OR (d) ISSUE BY RECLASSIFICATION OF SHARES OF COMMON STOCK ANY SHARES OF CAPITAL STOCK OF THE COMPANY, THE CONVERSION PRICE SHALL BE MULTIPLIED BY A FRACTION OF WHICH THE NUMERATOR SHALL BE THE NUMBER OF SHARES OF COMMON STOCK (EXCLUDING TREASURY SHARES, IF ANY) OUTSTANDING BEFORE SUCH EVENT AND OF WHICH THE DENOMINATOR SHALL BE THE NUMBER OF SHARES OF COMMON STOCK OUTSTANDING AFTER SUCH EVENT. ANY ADJUSTMENT MADE PURSUANT TO THIS SECTION 14.4 SHALL BECOME EFFECTIVE IMMEDIATELY AFTER THE RECORD DATE FOR THE DETERMINATION OF STOCKHOLDERS ENTITLED TO RECEIVE SUCH DIVIDEND OR DISTRIBUTION AND SHALL BECOME EFFECTIVE IMMEDIATELY AFTER THE EFFECTIVE DATE IN THE CASE OF A SUBDIVISION, COMBINATION OR RE-CLASSIFICATION. (ii) IF THE COMPANY, AT ANY TIME WHILE ANY NOTES ARE OUTSTANDING, SHALL DISTRIBUTE TO ALL HOLDERS OF COMMON STOCK EVIDENCES OF ITS INDEBTEDNESS OR ASSETS OR RIGHTS OR WARRANTS TO SUBSCRIBE FOR OR PURCHASE ANY SECURITY (EXCLUDING THOSE REFERRED TO IN SECTION 14.4(a)(i) ABOVE), THEN IN EACH SUCH CASE THE CONVERSION PRICE SHALL BE DETERMINED BY MULTIPLYING THE CONVERSION 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 MARKET PRICE OF COMMON STOCK DETERMINED AS OF THE RECORD DATE MENTIONED ABOVE, AND OF WHICH THE NUMERATOR SHALL BE SUCH MARKET PRICE OF THE COMMON STOCK 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 SHARE OF COMMON STOCK AS DETERMINED BY THE COMPANY'S BOARD OF DIRECTORS IN GOOD FAITH; PROVIDED, HOWEVER, THAT IF THE NOTEHOLDER DISPUTES SUCH AMOUNT, THE NOTEHOLDER MAY SELECT A NATIONALLY RECOGNIZED OR MAJOR REGIONAL INVESTMENT BANKING FIRM OR FIRM OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS OF RECOGNIZED STANDING (AN "APPRAISER") PAID FOR BY THE NOTEHOLDER AND THE COMPANY EQUALLY, IN WHICH CASE THE FAIR MARKET VALUE SHALL BE EQUAL TO THE AVERAGE OF THE DETERMINATIONS BY THE COMPANY'S BOARD OF DIRECTORS AND SUCH APPRAISER. IN EITHER CASE THE ADJUSTMENTS SHALL BE DESCRIBED IN A STATEMENT PROVIDED TO THE NOTEHOLDER OF THE NOTES 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) In case the Company (i) consolidates with or merges into any other entity and is not the continuing or surviving entity of such consolidation or merger, or (ii) permits any other entity to consolidate with or merge into the Company and the Company is the continuing or surviving Company but, in connection with such consolidation or merger, the Common Stock is changed into or exchanged for common stock or other securities of any other entity or cash or any other assets, or (iii) transfers all or substantially all of its properties and assets to any other entity, or (iv) effects a reorganization or reclassification of the equity of the Company in such a way that holders of Common Stock shall be entitled to receive stock, securities, cash or assets with respect to or in exchange for Common Stock, then, and in each such case, proper provision shall be made so that, upon the exercise of the Notes at any time after the consummation of such consolidation, merger, transfer, reorganization or reclassification, the Noteholder shall be entitled to receive (at the Conversion Price in effect for Common Stock issuable upon such conversion of the Notes immediately prior to such consummation), in lieu of Common Stock issuable upon such exercise of the Note prior to such consummation, the stock and other securities, cash and assets to which the Noteholder would have been entitled upon such consummation if such Holder had so exercised the Note immediately prior thereto. (iv) In the event that the Company issues or sells any Common Stock or securities which are convertible into or exchangeable for its Common Stock, or any rights, options or warrants to subscribe for or to purchase of its Common Stock for "Consideration" (as defined below) at a price per share ("Per Share Selling Price") which is less than the Conversion Price in effect immediately prior to the time of such issue or sale, then the Conversion Price shall be adjusted downward to equal such lower Per Share Selling Price effective concurrently with such issue or sale. Notwithstanding the foregoing, the foregoing adjustments shall not apply to the issuance of (A) shares of Common Stock upon exercise of rights, options, warrants and other convertible securities outstanding on the date of this Agreement and listed in the Company's SEC Filings, or (B) shares of Common Stock issued upon the exercise of stock options granted pursuant to the Company's employee stock option plan in effect from time to time (and as amended if approved by the stockholders of the Company). 16 For purposes of this Section 14.4(a)(iv), the following provision will be applicable (V) In the case of an issue or sale for cash of shares of Common Stock, the "Consideration" received by the Company therefor shall be deemed to be the amount of cash received, before deducting therefrom any commissions or expenses paid by the Company. (W) In case of the issuance (otherwise than upon conversion or exchange of obligations or shares of stock of the Company) of additional shares of Common Stock for a consideration other than cash or a consideration partly other than cash, the amount of the consideration other than cash received by the Company for such shares shall be deemed to be the fair value of such consideration as determined in good faith by the Company's board of directors. (X) In the case of the issuance by the Company in any manner of any rights to subscribe for or to purchase shares of Common Stock, or any options for the purchase of shares of Common Stock or stock convertible into Common Stock, all shares of Common Stock or stock convertible into Common Stock to which the holders of such rights or options shall be entitled to subscribe for or purchase pursuant to such rights or options shall be deemed to be outstanding as of the date of the offering of such rights or the granting of such options, as the case may be, and the minimum aggregate consideration named in such rights or options for the shares of Common Stock or stock convertible into Common Stock covered thereby, plus the consideration, if any, received by the Company for such rights or options, shall be deemed to be the "Consideration" received by the Company (as of the date of the offering of such rights or the granting of such options, as the case may be) for the issuance of such shares. (Y) In case of the issuance or issuances by the Company in any manner of any obligations or of any shares of stock of the Company that shall be convertible into or exchangeable for Common Stock, all shares of Common Stock issuable upon the conversion or exchange of such obligations or shares shall be deemed to be issued as of the date such obligations or shares are issued, and the amount of the "Consideration" received by the Company for such additional shares of Common Stock shall be deemed to be the total of (x) the amount of consideration received by the Company upon the issuance of such obligations or shares, as the case may be, plus (y) the minimum aggregate consideration, if any, other than such obligations or shares, receivable by the Company upon such conversion or exchange, except in adjustment of dividends. (Z) The amount of the "Consideration" received by the Company upon the issuance of any rights or options referred to in subparagraph (X) above or upon the issuance of any obligations or shares which are convertible or exchangeable as described in subparagraph (Y) above, and the amount of the consideration, if any, other than such obligations or shares so convertible or exchangeable, receivable by the Company upon the exercise, conversion or exchange thereof shall be determined in the same mariner provided in subparagraphs (V) and (W) above with respect to the consideration received by the Company in case of the issuance of additional shares of Common Stock; provided, however, that if such obligations or shares of stock so convertible or exchangeable are issued in payment or satisfaction of any dividend upon any stock of the Company other than Common Stock, the amount of the "Consideration" received by the Company upon the original issuance of such obligations or shares of stock so convertible or exchangeable shall be deemed to be the value of such obligations or shares of stock, as of the date of the adoption of the resolution declaring such dividend, as determined by the board of directors as of that date. Upon the expiration of any rights or options referred to in subparagraph (X), or the termination of any right of conversion or exchange referred to in subparagraph (Y), or any change in the number of shares of Common Stock deliverable upon exercise of such options or tights or upon conversion of or exchange of such convertible or exchangeable securities, the Conversion Price then in effect shall forthwith be readjusted to such Conversion Price as would have obtained had the adjustments made upon the issuance of such options, rights or convertible or exchangeable securities been made upon the basis of the delivery of only the number of shares of Common Stock actually delivered or to be delivered upon the exercise of such rights or options or upon the conversion or exchange of such securities. 17 (b) Notwithstanding the foregoing provisions, no adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease in such Conversion Price of more than $.01; provided, however, that any adjustments which by reason of this paragraph (b) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. (c) All calculations under this Section 14.4 shall be made to the nearest cent. (d) Whenever the Conversion Price is adjusted as herein provided, the Company shall determine the adjusted Conversion Price in accordance with this Section 14.4 and shall prepare an Officers' Certificate setting forth such adjusted Conversion Price and showing in detail the facts upon which such adjustment is based; such Officers' Certificate shall forthwith be filed with the Agent, who may rely on such Officers' Certificate as conclusive evidence of the correctness of such adjustment, and a notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price shall as soon as practicable be mailed by or on behalf of the Company to the holders at their last addresses as they shall on the appropriate Schedule. 14.5 NOTICE OF CERTAIN EVENTS.
