Neither such inquiries nor any other investigation conducted by or on behalf of such Purchaser or its representatives or counsel shall modify, amend or affect such Purchaser's right to rely on the truth, accuracy and completeness of the Disclosure Materials and the Company's representations and warranties contained in the Transaction Documents. (g) General Solicitation. Such Purchaser is not purchasing the Securities as a result of or subsequent to any advertisement, article, notice or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general solicitation or general advertisement.

(i) Trading in the Common Stock. During the thirty (30) Trading Days immediately preceding the Closing Date, such Purchaser has neither established a position in the Common Stock nor engaged in any trading activity with respect to the Common Stock. The Company acknowledges and agrees that no Purchaser makes or has made representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in this Section 2.2. ARTICLE III OTHER AGREEMENTS OF THE PARTIES 3.1 Transfer Restrictions. (a) Securities may only be disposed of pursuant to an effective registration statement under the Securities Act, to the Company or pursuant to an available exemption from or in a transaction not subject to the registration requirements of the Securities Act, and in compliance with any applicable federal and state securities laws. In connection with any transfer of Securities other than pursuant to an effective registration statement or to the Company, except as otherwise set forth herein, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration under the Securities Act. Notwithstanding the foregoing, the Company, without requiring a legal opinion as described in the immediately preceding sentence, hereby consents to and agrees to register on the books of the Company and with any transfer agent for the securities of the Company any transfer of Securities by a Purchaser to an Affiliate of such Purchaser or to one or more funds or managed accounts under common management with such Purchaser, and any transfer among any such Affiliates or one or more funds or managed accounts, provided that: (A) the transferee certifies to the Company that it is an "accredited investor" within the meaning of Rule 501(a) under the Securities Act and that it is acquiring the Securities solely for investment purposes (subject to the qualifications hereof) and (B) any such transfer does not constitute a public distribution of securities. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and shall have the rights of a Purchaser under this Agreement and the Registration Rights Agreement. (b) The Purchasers agree to the imprinting, so long as is required by this Section 3.1(b), of the following legend on the Securities: [NEITHER] THESE SECURITIES [NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE EXERCISABLE] HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. Neither Shares nor Underlying Shares shall contain the legend set forth above nor any other legend at any time while an Underlying Shares Registration Statement is effective under the Securities Act or, in the event there is not an effective Underlying Shares Registration Statement at such time if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission). The Company shall cause its counsel to issue the legal opinion included in the Transfer Agent Instructions to the Company's transfer agent on the day that such Underlying Shares Registration Statement is declared effective by the Commission (the "Effective Date"). The Company agrees that if any Shares or Underlying Shares are issued with a legend in accordance with this Section 3.1(b), it will, within three (3) Trading Days after request therefor by a Purchaser and the surrender by such Purchaser of the certificate representing the applicable Shares or Underlying Shares, provide such Purchaser with a certificate or certificates representing such Shares or Underlying Shares, free from such legend at such time as such legend would not have been required under this Section 3.1(b) had such issuance occurred on the date of such request. The Company may not make any notation on its records or give instructions to any transfer agent of the Company which enlarge the restrictions of transfer set forth in this Section. 3.2 Acknowledgment of Dilution. The Company acknowledges that the issuance of Underlying Shares upon exercise of the Warrants will result in dilution of the outstanding shares of Common Stock, which dilution may be substantial under certain market conditions. The Company further acknowledges that its obligation to issue Underlying Shares upon exercise of the Warrants pursuant to the terms thereof is unconditional and absolute regardless of the effect of any such dilution. 3.3 Furnishing of Information. As long as the Purchasers own Securities, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act. So long as the Purchasers own Securities, if the Company is not required to file reports pursuant to such laws, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) promulgated under the Securities Act such information as is required for the Purchasers to sell the Securities under Rule 144 promulgated under the Securities Act. The Company further covenants that it will take such further action as any holder of Securities may reasonably request, all to the extent required from time to time to enable such Person to sell Underlying Shares without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including the legal opinion referenced above in this Section. Upon the request of any such Person, the Company shall deliver to such Person a written certification of a duly authorized officer as to whether it has complied with such requirements. 3.4 Integration. The Company shall not, and shall use its best efforts to ensure that, no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Purchasers or that would be integrated with the offer or sale of the Securities for purposes of the rules and regulations of the AMEX. 3.5 Increase in Authorized Shares. If on any date the Company would be, if a notice of exercise were to be delivered on such date, precluded from issuing the sum of (i) 200% of the number of Underlying Shares then issuable upon exercise in full of the Adjustable Warrants and (ii) the number of Underlying Shares issuable upon exercise in full of the Closing Warrants (the "Current Required Minimum") due to the unavailability of a sufficient number of authorized but unissued or reserved shares of Common Stock, then the Board of Directors of the Company shall promptly (and in any case, within 30 Business Days from such date) prepare and mail to the stockholders of the Company proxy materials requesting authorization to amend the Company's articles of incorporation to increase the number of shares of Common Stock which the Company is authorized to issue to at least such number of shares as is reasonably adequate to enable the Company to comply with its issuance, exercise and reservation of shares obligations as set forth in this Agreement and the Warrants (the sum of (x) the number of shares of Common Stock then outstanding plus all shares of Common Stock issuable upon exercise of all outstanding options, warrants and convertible instruments other than the Warrants, and (y) the Current Required Minimum, shall be a reasonable number). In connection therewith, the Board of Directors shall (a) adopt proper resolutions authorizing such increase, (b) recommend to and otherwise use its best efforts to promptly and duly obtain stockholder approval to carry out such resolutions (and hold a special meeting of the stockholders no later than the earlier to occur of the 60th day after delivery of the proxy materials relating to such meeting and the 90th day after request by a holder of Warrants to issue the number of Underlying Shares in accordance with the terms hereof) and (c) within five (5) Business Days of obtaining such stockholder authorization, file an appropriate amendment to the Company's articles of incorporation to evidence such increase. 3.6 Reservation and Listing of Underlying Shares. (a) The Company shall (i) in the time and manner required by the AMEX and such other national securities exchange or market or trading or quotation facility on which the Common Stock is then listed for trading, prepare and file with the AMEX (and such other national securities exchange or market or trading or quotation facility on which the Common Stock is then listed for trading) an additional shares listing application covering a number of shares of Common Stock which is not less than the Initial Minimum, (ii) take all steps necessary to cause such shares of Common Stock to be approved for listing in the AMEX (as well as on any such other national securities exchange or market or trading or quotation facility on which the Common Stock is then listed) as soon as possible thereafter, and (iii) provide to the Purchasers evidence of such listing, and the Company shall maintain the listing of its Common Stock thereon. If the number of Underlying Shares issuable upon exercise of the then unexercised portion of the Warrants exceeds 85% of the number of Underlying Shares previously listed on account thereof with AMEX (and any such other required exchanges), then the Company shall take the necessary actions to immediately list a number of Underlying Shares as equals no less than the then Current Required Minimum with respect thereto. (b) The Company shall maintain a reserve of shares of Common Stock for issuance upon exercise in full of the Warrants in accordance with the Warrants, in such amount as may be required to fulfill its obligations in full under the Warrants, which reserve shall equal no less than the then Current Required Minimum. 3.7 Exercise Procedures.

Each of the Company and the Purchasers shall give prompt written notice to the other of any breach by it of any representation, warranty or other agreement contained in any Transaction Document, as well as any events or occurrences arising after the date hereof which would reasonably be likely to cause any representation or warranty or other agreement of such party, as the case may be, contained therein to be incorrect or breached as of the Closing Date.

In addition, other than with respect to any matter in which any of the Purchasers is a named party, the Company will pay such Purchaser the charges, as reasonably determined by such Purchaser, for the time of any officers or employees of such Purchaser devoted to appearing and preparing to appear as witnesses, assisting in preparation for hearings, trials or pretrial matters, or otherwise with respect to inquiries, hearings, trials, and other proceedings relating to the subject matter of this Agreement. The reimbursement obligations of the Company under this paragraph shall be in addition to any liability which the Company may otherwise have, shall extend upon the same terms and conditions to any Affiliates of the Purchasers who are actually named in such action, proceeding or investigation, and partners, directors, agents, employees and controlling persons (if any), as the case may be, of the Purchasers and any such Affiliate, and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company, the Purchasers and any such Affiliate and any such Person. The Company also agrees that neither the Purchasers nor any such Affiliates, partners, directors, agents, employees or controlling persons shall have any liability to the Company or any Person asserting claims on behalf of or in right of the Company in connection with or as a result of the consummation of the Transaction Documents except to the extent that any losses, claims, damages, liabilities or expenses incurred by the Company result from the gross negligence or willful misconduct of the applicable Purchaser or entity in connection with the transactions contemplated by this Agreement. 3.13 Redemption at the Option of the Company. (a) Subject to the provisions of this Section, commencing on the Effective Date, the Company shall have the right, upon thirty (30) Trading Days' notice to the Purchasers which may not be given until after the Effective Date (an "Optional Redemption Notice" and the date such notice is received by the Purchasers, the "Notice Date"), to redeem all or a portion of the Shares then held by the Purchasers at a cash price equal to the Optional Redemption Price (as defined below). The Company may only deliver an Optional Redemption Notice to the Purchasers if, on the Notice Date: (i) either there is an effective Underlying Shares Registration Statement pursuant to which the Purchasers are permitted to utilize the prospectus thereunder to sell Shares or Shares may be sold without volume restrictions pursuant to Rule 144 promulgated under the Securities Act, as determined by counsel to the Company pursuant to a written opinion letter, addressed and delivered prior to the Notice Date to the Company's transfer agent in the form and substance acceptable to the Purchasers and such transfer agent and (ii) the Common Stock is listed for trading on the AMEX or on a Subsequent Market (as defined in the Adjustable Warrants). If any of the foregoing conditions shall cease to be in effect during the period between the Notice Date and the date the Optional Redemption Payment is paid in full, then the Purchasers subject to such redemption may elect, by written notice to the Company given at any time after any of the foregoing conditions shall cease to be in effect, to invalidate ab initio such redemption, notwithstanding anything herein contained to the contrary. The Purchasers may sell any portion of the Shares subject to an Optional Redemption Notice prior to the date that the Optional Redemption Price is due and paid in full. (b) The Optional Redemption Price is due on the thirtieth (30th) Trading Day following the Notice Date. If any portion of the Optional Redemption Price shall not be paid by the Company by expiration of such thirtieth (30th) Trading Day, interest shall accrue thereon at the rate of 18% per annum (or the maximum rate permitted by applicable law, whichever is less) until the Optional Redemption Price plus all such interest is paid in full. In addition, if any portion of the Optional Redemption Price remains unpaid after such date, the Purchasers subject to such redemption may elect, by written notice to the Company given at any time thereafter, to invalidate ab initio such redemption, notwithstanding anything herein contained to the contrary. If a Purchaser elects to invalidate such redemption the Company shall promptly, and, in any event, not later than three (3) Trading Days from receipt of such Purchaser's notice of such election, return to such Purchaser all of the Shares for which the Optional Redemption Price shall not have been paid in full. (c) The "Optional Redemption Price" for each Share to be redeemed shall equal the sum of (i) 120% multiplied by the greater of (A) the average of the Per Share Market Values for the five (5) Trading Days immediately preceding the date the Optional Redemption Price is paid in full, and (B) the most recent Adjustment Price (as defined in the Adjustable Warrants), or if such optional redemption occurs prior to the First Vesting Date, the Initial Closing Price (as defined in the Adjustable Warrants), and (ii) all other amounts, costs, expenses and liquidated damages due in respect of such Shares. 3.14 Redemption at the Option of the Purchasers. (a) Upon the occurrence of a Triggering Event (as defined below), each Purchaser shall have the right, exercisable at the sole option of such Purchaser, to require the Company to redeem all or a portion of the Shares then held by such Purchaser for a redemption price, in cash, equal to the Mandatory Redemption Price (as defined below). The Mandatory Redemption Price shall be due and payable within five (5) Trading Days of the date on which the notice for the payment therefor is provided by a Purchaser (the date such notice is delivered, the "Mandatory Redemption Date"). If the Company fails to pay the Mandatory Redemption Price hereunder in full pursuant to this Section on the date such amount is due in accordance with this Section, the Company will pay interest thereon at a rate of 18% per annum (or the lesser amount permitted by applicable law), accruing daily from such date until the Mandatory Redemption Price, plus all such interest thereon, is paid in full. (b) A "Triggering Event" means any one or more of the following events (whatever the reason and whether it shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court, or any order, rule or regulation of any administrative or governmental body): (i) after the Effective Date, the effectiveness of the Underlying Shares Registration Statement lapses for any reason or the Purchasers shall not be permitted to resell Registrable Securities (as defined in the Registration Rights Agreement) under the Underlying Shares Registration Statement, in either case, for more than an aggregate of thirty (30) days (which need not be consecutive days); (ii) for an aggregate of five (5) consecutive days, at the direction of the Company or due to events or circumstances within the control of the Company, there shall be no closing bid prices for the Company reported by Bloomberg Information Services, Inc. (or any successor entity thereto to the function of reporting stock prices); (iii) the failure of the Common Stock to be listed for trading on the AMEX or on a Subsequent Market or the suspension of the Common Stock from trading on the AMEX or on a Subsequent Market, in either case, at the direction of the Company or due to events or circumstances within the control of the Company; (iv) the Company shall either be a party to any Change of Control Transaction (as defined below) or agree to sell (in one or a series of related transactions) all or substantially all of its assets (whether or not such sale would constitute a Change of Control Transaction). "Change of Control Transaction" means the occurrence of any of (i) an acquisition after the date hereof by an individual or legal entity or "group" (as described in Rule 13d-5(b)(1) promulgated under the Exchange Act) of effective control (whether through legal or beneficial ownership of capital stock of the Company, by contract or otherwise) of in excess of 33% of the voting securities of the Company, except as a result of a tender offer to the holders of the Common Stock that is not approved by the Board, (ii) a replacement at one time or over time of more than one-half of the members of the Company's board of directors which is not approved by a majority of those individuals who are members of the board of directors on the date hereof (or by those individuals who are serving as members of the board of directors on any date whose nomination to the board of directors was approved by a majority of the members of the board of directors who are members on the date hereof), (iii) the merger of the Company with or into another entity which either is not listed for trading on the AMEX or a Subsequent Market or in which the holders of the Company's securities prior to the first such transaction do not own a minimum of 51% of the outstanding capital stock of the surviving entity, or (iv) the execution by the Company of an agreement to which the Company is a party or by which it is bound, providing for any of the events set forth above in (i) - (iii); (v) the Company shall fail to observe or perform any other covenant, agreement or warranty contained in, or otherwise commit any breach of the Transaction Documents, and such failure or breach shall not, if subject to the possibility of a cure by the Company, have been remedied within five (5) days after the date on which notice of such failure or breach shall have been given. (vi) there shall have occurred a "Triggering Event" under the Company's Securities Purchase Agreement, dated December 8, 1999, except that no Triggering Event hereunder will be deemed to have occurred if the Company shall have complied with its obligations under Section 3(c) of the Registration Rights Agreement, dated as of December 8, 1999, among the Purchasers and the Company, by timely filing the additional registration statement, if any, required to be filed under such agreement, unless such additional registration statement is not declared effective by the Commission by the 70th day following the date that such registration statement was first required to have been filed. (c) Notwithstanding anything herein to the contrary, in the event one or more of the Triggering Events would cause the Company's auditors to characterize the issuance of the Shares as a debt issuance then the Company and the Purchasers agree to discuss any changes to the Transaction Documents in order to avoid the characterization of the issuance of the Shares by the Company's auditors as a debt issuance. The "Mandatory Redemption Price" for each Share to be redeemed shall equal the sum of (i) 120% multiplied by the greater of (A) the average of the Per Share Market Values for the five (5) Trading Days preceding the Mandatory Redemption Date, (B) the average of the Per Share Market Values for the five (5) Trading Days preceding the date the {Mandatory} Redemption Price is paid in full, and (C) the most recent Adjustment Price, or if such optional redemption occurs prior to the First Vesting Date, the Initial Closing Price, and (ii) all other amounts, costs, expenses and liquidated damages due in respect of such Shares. 3.15 Certain Trading Restrictions. Each Purchaser agrees that from the period commencing on the Closing Date and ending on the Expiration Date (as defined in the Adjustable Warrants) it will not, during the 35 Trading Days preceding each Vesting Date (as defined in the Adjustable Warrants), enter into any Short Sales (as defined herein).

For purposes of determining whether there is an equivalent offsetting long position in Common Stock held by a Purchaser, Warrant Shares that have not yet been issued on exercise of the Warrants held by a Purchaser shall be deemed to be held long by such Purchaser.
