The Purchaser and any registered assigns thereof are referred to as the "Holder." This Note is originally being issued pursuant to the Securities Purchase Agreement dated the date hereof (the "Securities Purchase Agreement"), by and between the Company and the Purchaser, and the Holder is entitled to all of the benefits of the Securities Purchase Agreement, and may enforce the agreements contained herein and therein and exercise the remedies provided for hereby and thereby or otherwise available in respect hereof and thereof, all in accordance with the terms hereof and thereof. Capitalized terms used and not defined herein shall have the meanings ascribed to them in the Securities Purchase Agreement. The following terms shall apply to this Note: 1. Principal and Interest Payments. The principal amount of this Note shall be due and payable in full upon April 8, 2008 (the "Maturity Date"). Interest (a) shall accrue on the unpaid principal amount of this Note from the date hereof at the rate of 6% per annum, (b) shall be compounded semi-annually on October 8 and April 8 of each year and (c) shall be due and payable in cash (i) on each April 8, commencing on April 8, 2004, (ii) on the Maturity Date of this Note, and (iii) after such Maturity Date, on demand. Any principal and interest not paid when due (whether at maturity or at a date fixed for prepayment or repurchase or otherwise) shall bear interest from and including the date due to but excluding the date paid in full at the rate of 10% per annum. Interest shall be calculated on the basis of the actual number of days elapsed in a 365-day year and shall in no event exceed the maximum rate permitted under applicable law. 2. Optional Prepayment. The principal amount of this Note may be prepaid without penalty in whole or in part, together with accrued and unpaid interest thereon, at the option of the Company upon delivery of written notice to the Holder ("Prepayment Notice") specifying a prepayment date (the "Prepayment Date") no earlier than twenty (20) days nor later than thirty (30) days subsequent to the delivery of such notice, provided, however, that no such Prepayment Notice shall be issued unless the average closing price of a share of the Company's common stock, $0.001 par value per share (the "Common Stock"), on the principal securities market on which such shares shall then be traded for a twenty (20) consecutive trading-day period ending within five (5) days of the issuance of the Prepayment Notice shall have equaled or exceeded $3.75 per share (appropriately adjusted for any stock split or combination or any stock dividend or other recapitalization affecting such shares after the date hereof). The term "Common Stock" shall include, unless the context otherwise requires, the stock or other securities or property at the time deliverable upon conversion of this Note. 3. Conversion. 3.1. Conversion. (a) The Holder shall have the right at any time prior to the Maturity Date or a Prepayment Date to convert in whole or in part the unpaid principal of this Note, and accrued and unpaid interest thereon, into such number of fully-paid and nonassessable shares of Common Stock as is determined by dividing the aggregate amount of principal and interest to be converted by the conversion price in effect on the date this Note is surrendered for conversion (the "Conversion Price"); provided, that, following any Prepayment Date, a Holder shall continue to have the right to convert any principal of this Note that remains unpaid, together with accrued and unpaid interest thereon. The initial Conversion Price shall be $2.75 per share of Common Stock. Such initial Conversion Price shall be subject to adjustment as set forth in Paragraph 4. (b) The Holder shall notify the Company of its intention to convert all or a portion of this Note pursuant to this Paragraph 3.1. Within five (5) Business Days after the date of such notice of intention, the Company shall deliver to the Holder a certificate, signed by the Company's Chief Executive Officer and Chief Financial Officer, to the effect that: (i) since the end of the Company's most recently completed fiscal year, there has been no material adverse change in the business, assets, properties, liabilities, condition (financial or otherwise) or results of operations of the Company or any of its subsidiaries; (ii) there is no material action, suit or proceeding, or governmental inquiry or investigation, pending, or, to the best of the Company's knowledge, threatened, against the Company or any of its subsidiaries; and (iii) neither the Company nor, to the best of the Company's knowledge, any other party thereto is in default in any material respect of any of its obligations under any material agreement or contract of the Company. If, for any reason, the Company is unable to certify as to any of the above matters, it shall so notify the Holder, and shall deliver a certificate as to the remaining matters, within such five (5) Business Day period. The delivery of any certificate by the Company to the Holder pursuant to this Paragraph 3.1(b) shall not obligate the Holder to convert this Note. 2 3.2. Automatic Conversion. The principal amount of this Note, together with accrued and unpaid interest thereon, shall be automatically converted into shares of Common Stock at the Conversion Price then in effect, immediately upon the closing of a sale of the Common Stock in a firm commitment underwritten public offering pursuant to a registration statement under the Securities Act, the public offering price of which is not less than $3.75 per share (appropriately adjusted for any stock split, dividend, combination or other recapitalization affecting such shares after the date hereof) and which results in aggregate cash proceeds to the Company of no less than $50,000,000 (net of underwriting discounts and commissions) (a "Qualifying IPO"). 3.3. Mechanics of Conversion. Before any Holder of this Note shall be entitled to receive the Common Stock into which this Note has been converted, such Holder shall surrender this Note duly endorsed at the Company's principal corporate office and, if such conversion is being made pursuant to Paragraph 3.1, shall give written notice to the Company, at its principal corporate office, of the election to convert this Note, further stating therein the amount of the principal and interest to be converted and the name or names in which the certificate or certificates for the Common Stock are to be issued. The Company shall, as soon as practicable after such surrender of this Note, issue and deliver to such Holder at the address specified by such Holder, or to the nominee or nominees of such Holder, a certificate or certificates for the Common Stock, together with any other securities and property, to which such person or persons shall be entitled as aforesaid. Except as otherwise provided in Paragraph 3.2, such conversion shall be deemed to have been made immediately prior to the close of business on the date on which this Note shall have been surrendered for conversion and the person or persons entitled to receive the Common Stock shall be treated for all purposes as the record holder or holders of such Common Stock as of such date. If the conversion pursuant to Paragraph 3.1 is in connection with an underwritten offering of securities registered pursuant to the Securities Act, the conversion may, at the option of the Holder of this Note, be conditioned upon the closing with the underwriters of the sale of securities pursuant to such offering, in which event the Holder shall not be deemed to have converted this Note until immediately prior to the closing of such sale of securities. Upon any partial conversion of this Note, the Company, at its expense, will forthwith issue and deliver to the Holder a new Note in a principal amount equal to the unconverted principal amount of the surrendered Note, such new Note to be dated and to bear interest from the date to which interest has been paid on the surrendered Note. 4. Adjustments. 4.1. Subdivision or Combination of Stock. In the event the Company should at any time or from time to time after the date hereof subdivide its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced, and conversely, if the outstanding shares of Common Stock of the Company are combined into a smaller number of shares, the Conversion Price in effect immediately prior to such combination shall be proportionately increased. 4.2. Dividends in Common Stock, Other Stock, Property, Reclassification. If at any time or from time to time the holders of Common Stock receive or become entitled to receive, without payment therefor: 3 (a) Common Stock or any shares of stock or other securities that are at any time directly or indirectly convertible into or exchangeable for Common Stock, or any rights, warrants or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution; (b) any cash paid or payable otherwise than as a cash dividend, evidences of the Company's indebtedness or any other asset; or (c) Common Stock or additional stock or other securities or property (including cash) by way of distribution, spinoff, split-up, reclassification, combination of shares or similar corporate rearrangement or otherwise (other than shares of Common Stock issued as a stock split, which are covered by the terms of Paragraph 4.1), then, and in each such case, the Holder shall, upon the conversion of this Note, be entitled to receive, in addition to the number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and property (including cash in the cases referred to in clauses (b) and (c) above) that the Holder would have received or been entitled to receive had it been the holder of record of such number of shares of Common Stock as of the date on which holders of Common Stock received or became entitled to receive such shares or all other additional stock and other securities and property. 4.3. Reorganization, Reclassification, Consolidation, Merger or Sale. If any recapitalization, reclassification or reorganization of the capital stock of the Company, or any consolidation or merger of the Company with another entity, or the sale of all or substantially all of its assets in one or a series of transactions, or other transaction, is effected and, in connection therewith, holders of Common Stock are entitled to receive stock, securities, or other assets or property (an "Organic Change"), then, as a condition of such Organic Change, lawful and adequate provisions shall be made by the Company whereby the Holder shall thereafter have the right to receive (in lieu of the shares of the Common Stock of the Company immediately theretofore receivable upon the conversion of this Note) upon conversion of this Note such shares of stock, securities or other assets or property 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 immediately theretofore receivable upon the conversion of this Note. In the event of any Organic Change, appropriate provision shall be made by the Company with respect to the rights and interests of the Holder of this Note to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Conversion Price and of the number and type of shares and other securities and property receivable upon the conversion of this Note) shall thereafter be applicable, in relation to any shares of stock, securities or other assets or property thereafter deliverable upon the conversion hereof. The Company shall not effect any such consolidation, merger or sale unless, prior to the consummation thereof, the successor entity (if other than the Company) resulting from such consolidation or merger or the entity purchasing such assets shall assume by written instrument delivered to the Company and to the Holder the obligation to deliver to the Holder such shares of stock, securities or other assets or property as, in accordance with the foregoing provisions, the Holder may be entitled to receive, as well as the obligations of the Company set forth in the immediately preceding 4 sentence. The above provisions shall similarly apply with respect to successive recapitalizations, reclassifications, reorganizations, consolidations, mergers, sales or other transactions. 4.4. Adjustments to Conversion Price for Certain Diluting Issues. In the event that after the date hereof any transaction or event, other than those described in Paragraphs 4.1 through 4.3 above, occurs which, pursuant to the provisions of the Company's Third Restated Certificate of Incorporation (as the same may be amended or restated, the "Certificate of Incorporation"), results in a change in the conversion price of the Company's Series C Preferred Stock, par value $0.001 per share (the "Series C Preferred Stock"), whether by reason of the full-ratchet or weighted average antidilution calculations pertaining to the Series C Preferred Stock, then simultaneously with each such change in the conversion price of the Series C Preferred Stock, the Conversion Price shall be reset to equal 1.316 times the new conversion price of the Series C Preferred Stock. In respect of any such adjustment, the adjusted Conversion Price will be determined by reference to the provisions of the Company's Certificate of Incorporation as they shall be in effect at the time of any such transaction or event, and nothing herein contained shall be deemed to limit the Company's right, upon receipt of the appropriate consent of the holders of the Series C Preferred Stock, to modify the antidilution provisions applicable to the Series C Preferred Stock or to require the consent of the Purchaser to any such modification. 4.5. Certain Events. If any change in the outstanding Common Stock of the Company or any other event occurs as to which the other provisions of this Paragraph 4 are not strictly applicable or if strictly applicable would not fairly protect the rights of the Holder in accordance with such provisions, then the Board of Directors of the Company shall make an adjustment in the number, class and kind of shares available under the Note, the Conversion Price or the application of such provisions, so as to give the Holder upon conversion of the Note the total number, class and kind of shares as it would have owned had the Note been converted prior to the event and had it continued to hold such shares until after the event requiring adjustment. 4.6. Notices of Adjustments. Immediately upon any adjustment under this Paragraph 4, the Company shall give written notice thereof to the Holder, setting forth in reasonable detail and certifying the calculation of such adjustment, the adjusted Conversion Price and the adjusted number or type of shares of Common Stock or other securities or property issuable upon conversion hereof (as applicable) and describing the transactions giving rise to such adjustment. 4.7. Notices of Corporate Events. If the Company (i) declares a dividend or any other distribution of cash, securities or other property in respect of its Common Stock, (ii) authorizes or approves, enters into any agreement contemplating or solicits stockholder approval for any Organic Change or (iii) authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Company, then the Company shall deliver to the Holder a notice describing the material terms and conditions of such transaction at least 20 Business Days prior to the applicable record or effective date on which a person would need to hold Common Stock in order to participate in or vote with respect to such transaction, and the Company will take all steps reasonably necessary in order to ensure that the Holder is given the practical opportunity to convert this Note prior to such time so as to participate in or vote with respect to such 5 transaction. For purposes of this Note, "Business Day" shall mean any day (except Saturday or Sunday) on which banks are scheduled to be open to conduct business in the City of New York. 4.8. No Fractional Shares. No fractional shares shall be issued upon the conversion of this Note, and the number of shares of Common Stock to be issued shall be rounded to the nearest whole share (including a fraction equating to .5000 being rounded up to the next whole number). The number of shares issuable upon such conversion shall be determined on the basis of the unpaid principal and interest of this Note, as the case may be, the Holder is at the time converting into Common Stock and the number of shares of Common Stock issuable upon such aggregate conversion. 4.9. Reservation of Stock Issuable Upon Conversion. The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of this Note, such number of its shares of Common Stock as shall from time to time be sufficient to effect the conversion of this Note for the maximum number of shares of Common Stock issuable upon conversion of this Note; and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of this Note for the maximum number of shares of Common Stock then issuable upon conversion hereof, in addition to such other remedies as shall be available to the Holder, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite stockholder approval of any necessary amendment to the Certificate of Incorporation. 4.10. Fully Paid Shares. All shares of capital stock issued upon the conversion of this Note shall be validly issued, fully paid and non-assessable. 5. Repurchase Upon Change of Control. 5.1. Repurchase Right. In the event of a Change of Control (as hereinafter defined), the Company will make an offer to repurchase (the "Change of Control Offer") this Note at a purchase price in cash equal to the unpaid principal amount hereof, plus accrued and unpaid interest hereon to the date of repurchase. Within five days following the occurrence of any Change of Control, the Company shall give written notice of such Change of Control to the Holder, which notice shall state: (i) that a Change of Control has occurred and that the Holder has the right to require the Company to repurchase all or a portion of the Note at a purchase price in cash equal to the unpaid principal amount thereof, plus accrued and unpaid interest thereon (the "Repurchase Price") to the date of repurchase (the "Repurchase Date"), which shall be a Business Day, specified in such notice, that is not earlier than 20 days or later than 30 days after the date such notice is given; (ii) the then effective Conversion Price; and (iii) that payment will be made upon presentation and surrender of the Note. To exercise its repurchase right, the Holder shall give to the Company, within 10 days after its receipt of the Company's notice, written notice of its election to accept the Change of Control Offer (the "Election Notice"), which Election Notice shall set forth the principal amount of this Note to be repurchased and, if this Note is to be repurchased in part, the name and address of the person in which the portion thereof to remain outstanding after such repurchase is to be registered. Notwithstanding the 6 Holder's election to accept the Change of Control Offer and delivery of the Election Notice to the Company, the right of the Holder to convert this Note pursuant to Paragraph 3 shall continue until the close of business on the day immediately preceding the Repurchase Date. If the Holder has elected to accept the Change of Control Offer, then, on the Repurchase Date, the Holder shall surrender this Note to the Company at the office or agency of the Company maintained pursuant to Paragraph 10.1 and shall thereupon be entitled to receive payment of the Repurchase Price therefor. If the Holder elects to have repurchased less than the entire principal amount of this Note, the Company shall issue, at its expense, a new Note representing the portion of the principal amount not so repurchased, which new Note shall be dated as of the date (prior to the Repurchase Date) to which interest has been paid on the Note so surrendered. 5.2.
