Notwithstanding anything in this Section 2(a) to the contrary, by making the representations herein, the Purchaser does not agree to hold the Securities for any minimum or other specific term and reserves the right to dispose of the Securities at any time in accordance with or pursuant to a registration statement or an exemption from the registration requirements under the Securities Act.

(d) Information. Such Purchaser and its counsel, if any, have been furnished all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities which have been specifically requested by such Purchaser or its counsel. Such Purchaser and its counsel have been afforded the opportunity to ask questions of the Company and have received what such Purchaser believes to be satisfactory answers to any such inquiries. Neither such inquiries nor any other investigation conducted by such Purchaser or its counsel or any of its representatives shall modify, amend or affect such Purchaser's right to rely on the Company's representations and warranties contained in Section 3 below. Such Purchaser understands that such Purchaser's investment in the Securities involves a high degree of risk. (e) Governmental Review. Such Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed upon or made any recommendation or endorsement of the Securities. (f) Transfer or Resale. Such Purchaser understands that (i) except as provided in the Registration Rights Agreement, the sale or resale of the Securities have not been and are not being registered under the Securities Act or any state securities laws, and the Securities may not be transferred unless (a) the transfer is made pursuant to and as set forth in an effective registration statement under the Securities Act covering the Securities; or (b) such Purchaser shall have delivered to the Company an opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that the Securities to be sold or transferred may be sold or transferred pursuant to an exemption from such registration; or (c) sold under and in compliance with Rule 144 promulgated under the Securities Act (or a successor rule) ("RULE 144"); or (d) sold or transferred in accordance with applicable securities laws to an affiliate of such Purchaser who agrees to sell or otherwise transfer the Securities only in accordance with the provisions of this Section 2(f) and who is an Accredited Investor; and (ii) neither the Company nor any other person is under any obligation to register such Securities under the Securities Act or any state securities laws (other than pursuant to the Registration Rights Agreement). Notwithstanding the foregoing or anything else contained herein to the contrary, the Securities may be pledged as collateral in connection with a bona fide margin account or other lending arrangement, provided such pledge is consistent with applicable laws, rules and regulations. (g) Legends. Such Purchaser understands that the certificates for the Preferred Shares, Warrants and, until such time as the Conversion Shares and Warrant Shares have been registered under the Securities Act (including registration pursuant to Rule 416 thereunder) as contemplated by the Registration Rights Agreement or otherwise may be sold by such Purchaser under Rule 144(k), the certificates for the Conversion Shares and Warrant Shares shall bear a restrictive legend in substantially the following form: The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended, or the securities laws of any state of the United States or in any other jurisdiction. The securities represented hereby may not be offered, sold or transferred in the absence of an effective registration statement for the securities under applicable securities laws unless offered, sold or transferred pursuant to an available exemption from the registration requirements of those laws. The Company agrees that at any time the Registration Statement is effective, and assuming compliance with the applicable provisions of the Certificate of Designation or the Warrant, as applicable, the Company shall instruct its transfer agent to issue (and provide such transfer agent with any additional documentation that may be necessary to cause the Conversion Shares and the Warrant Shares to be issued without the restrictive legend above), in connection with the issuance of the Conversion Shares and Warrant Shares, certificates representing such Conversion Shares and Warrant Shares without the restrictive legend above, provided such Conversion Shares and Warrant Shares are to be sold pursuant to the prospectus contained in the Registration Statement. The parties acknowledge that the Company has certain rights with respect to transfers of the Securities as set forth in the Registration Rights Agreements. The legend set forth above shall be removed and the Company shall issue a certificate without such legend to the holder of any Security upon which it is stamped, if, unless otherwise required by state securities laws, (a) the sale of such Security is registered under the Securities Act (including registration pursuant to Rule 416 thereunder) as contemplated by the Registration Rights Agreement and the Security is sold pursuant to and as set forth in such Registration Statement and in the Securities Act; (b) such holder provides the Company with an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable transactions, to the effect that a public sale or transfer of such Security may be made without registration under the Securities Act; or (c) such holder provides the Company with reasonable assurances that such Security can be sold under Rule 144. In the event the above legend is removed from any Security and thereafter the effectiveness of a registration statement covering such Security is suspended or the Company determines that a supplement or amendment thereto is required by applicable securities laws, then upon reasonable advance written notice to such Purchaser the Company may require that the above legend be placed on any such Security that cannot then be sold pursuant to an effective registration statement or under Rule 144 and such Purchaser shall cooperate in the replacement of such legend. Such legend shall thereafter be removed when such Security may again be sold pursuant to an effective registration statement or under Rule 144. (h) Authorization; Enforcement. This Agreement and the Registration Rights Agreement have been duly and validly authorized, executed and delivered on behalf of such Purchaser and are valid and binding agreements of such Purchaser enforceable against such Purchaser in accordance with their terms. (i) Residency. Such Purchaser is a resident of the jurisdiction set forth under such Purchaser's name on the Execution Page hereto executed by such Purchaser. (j) No Short Sales. Neither such Purchaser nor any of its affiliates (as that term is defined in Rule 144 under the Securities Act) has, directly or indirectly, engaged in any short sale of, had in effect a short position in (whether such short sale or position was against the box and regardless of when such position was entered into), or granted any rights with respect to the Common Stock, at any time during the six month period immediately prior to the Closing Date. The Purchasers' representations and warranties made in this Article 2 are made solely for the purpose of permitting the Company to make a determination that the offer and sale of the Preferred Shares and Warrants pursuant to this Agreement complies with applicable U.S. federal and state securities laws and not for any other purpose. Accordingly, the Company should not rely on such representations and warranties for any other purpose. 3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

The capitalization of the Company as of the date hereof, including the authorized capital stock, the number of shares issued and outstanding, the number of shares issuable and reserved for issuance pursuant to the Company's stock option plans, the number of shares issuable and reserved for issuance pursuant to securities (other than the Preferred Shares and Warrants) exercisable or exchangeable for, or convertible into, any shares of capital stock and the number of shares to be reserved for issuance upon conversion of the Preferred Shares and exercise of the Warrants is set forth on Schedule 3(d). All of such outstanding shares of capital stock have been, or upon issuance in accordance with the terms of any such warrants, options or preferred stock, will be, validly issued, fully paid and non-assessable. No shares of capital stock of the Company (including the Preferred Shares, the Conversion Shares and the Warrant Shares) are subject to preemptive rights or any other similar rights of the stockholders of the Company or any liens or encumbrances. Except for the Securities and as set forth on Schedule 3(d), as of the date of this Agreement, (i) there are no outstanding options, warrants, scrip, rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities or rights convertible into or exercisable or exchangeable for, any shares of capital stock of the Company or any of its subsidiaries, or arrangements by which the Company or any of its subsidiaries is or may become bound to issue additional shares of capital stock of the Company or any of its subsidiaries, nor are any such issuances or arrangements contemplated, and (ii) there are no agreements or arrangements under which the Company or any of its subsidiaries is obligated to register the sale of any of its or their securities under the Securities Act (except the Registration Rights Agreements). Schedule 3(d) sets forth all of the Company issued securities or instruments containing antidilution or similar provisions that will be triggered by, and all of the resulting adjustments that will be made to such securities and instruments as a result of, the issuance of the Securities in accordance with the terms of this Agreement, the Certificate of Designation or the Warrants. The Company has furnished to the Purchasers true and correct copies of the Company's Certificate of Incorporation as in effect on the date hereof ("CERTIFICATE OF INCORPORATION"), the Company's By-laws as in effect on the date hereof (the "BY-LAWS"), and all other instruments and agreements governing securities convertible into or exercisable or exchangeable for capital stock of the Company.

(f) No Conflicts. The execution, delivery and performance of this Agreement, the Warrants and the Registration Rights Agreement by the Company, the performance by the Company of its obligations under the Certificate of Designation, and the consummation by the Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance and reservation for issuance, as applicable, of the Preferred Shares, Warrants, Conversion Shares and Warrant Shares) will not (i) result in a violation of the Certificate of Incorporation or By-laws or (ii) conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment (including, without limitation, the triggering of any anti-dilution provisions), acceleration or cancellation of, any agreement, indenture or instrument to which the Company or any of its subsidiaries is a party, or result in a violation of any law, rule, regulation, order, judgment or decree (including United States federal and state securities laws and regulations and rules or regulations of any self-regulatory organizations to which either the Company or its securities are subject) applicable to the Company or any of its subsidiaries or by which any property or asset of the Company or any of its subsidiaries is bound or affected (except, with respect to clause (ii), for such conflicts, defaults, terminations, amendments, accelerations, cancellations and violations that would not, individually or in the aggregate, have a Material Adverse Effect). Neither the Company nor any of its subsidiaries is in violation of its Certificate of Incorporation, By-laws or other organizational documents and neither the Company nor any of its subsidiaries is in default (and no event has occurred which, with notice or lapse of time or both, would put the Company or any of its subsidiaries in default) under, nor has there occurred any event giving others (with notice or lapse of time or both) any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Company or any of its subsidiaries is a party, except for actual or possible violations, defaults or rights that would not, individually or in the aggregate, have a Material Adverse Effect. The businesses of the Company and its subsidiaries are not being conducted, and shall not be conducted so long as a Purchaser owns any of the Preferred Shares, in violation of any law, ordinance or regulation of any governmental entity, except for possible violations the sanctions for which either singly or in the aggregate would not have a Material Adverse Effect. Except as specifically contemplated by this Agreement and the Registration Rights Agreement, the Company is not required to obtain any consent, approval, authorization or order of, or make any filing or registration with, any court or governmental agency or any regulatory or self regulatory agency in order for it to execute, deliver or perform any of its obligations under this Agreement, the Warrants or the Registration Rights Agreement or to perform its obligations under the Certificate of Designation, in each case in accordance with the terms hereof or thereof. The Company is not in violation of the listing requirements of the Nasdaq National Market ("NNM") and has received no notice regarding the potential delisting of the Common Stock by the NNM. (g) SEC Documents, Financial Statements. Since December 31, 2000, the Company has timely filed (within applicable extension periods) all reports, schedules, forms, statements and other documents required to be filed by it with the SEC pursuant to the reporting requirements of the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT") (all of the foregoing filed prior to the date hereof and all exhibits included therein and financial statements and schedules thereto and documents incorporated by reference therein, being hereinafter referred to herein as the "SEC DOCUMENTS"). The Company has delivered to each Purchaser true and complete copies of the SEC Documents. To the extent that any SEC Document is available under the SEC's EDGAR filing system prior to the date hereof, such SEC Document shall be deemed to have been delivered to each of the Purchasers. As of their respective dates, the SEC Documents complied in all material respects with the requirements of the Exchange Act or the Securities Act, as the case may be, and the rules and regulations of the SEC promulgated thereunder applicable to the SEC Documents, and none of the SEC Documents, at the time they were filed with the SEC, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. None of the statements made in any such SEC Documents is, or has been, required to be amended or updated under applicable law (except for such statements as have been amended or updated in subsequent filings made prior to the date hereof). As of their respective dates, the financial statements of the Company included in the SEC Documents complied as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC applicable with respect thereto. Such financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"), consistently applied, during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may not include footnotes or may be condensed or summary statements) and fairly present in all material respects the consolidated financial position of the Company and its consolidated subsidiaries as of the dates thereof and the consolidated results of their operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to immaterial year-end audit adjustments). Except as set forth in the financial statements of the Company included in the SEC Documents filed prior to the date hereof, the Company has no liabilities, contingent or otherwise, other than (i) liabilities incurred in the ordinary course of business subsequent to the date of such financial statements and (ii) obligations under contracts and commitments incurred in the ordinary course of business and not required under GAAP to be reflected in such financial statements, which liabilities and obligations referred to in clauses (i) and (ii), individually or in the aggregate, are not material to the financial condition or operating results of the Company. (h) Absence of Certain Changes. Since December 31, 2000, there has been no material adverse change and no material adverse development in the business, properties, operations, prospects, financial condition or results of operations of the Company and its subsidiaries, taken as a whole, except as disclosed in the SEC Documents filed prior to the date hereof. (i) Absence of Litigation. Except as disclosed in the SEC Documents filed prior to the date hereof, there is no action, suit, proceeding, inquiry or investigation before or by any court, public board, government agency, self-regulatory organization or body, including, without limitation, the SEC or NASDAQ, pending or, to the knowledge of the Company or any of its subsidiaries, threatened against or affecting the Company, any of its subsidiaries, or any of their respective directors or officers in their capacities as such. There are no facts which, if known by a potential claimant or governmental authority, could give rise to a claim or proceeding which, if asserted or conducted with results unfavorable to the Company or any of its subsidiaries, could reasonably be expected to have a Material Adverse Effect. (j) Intellectual Property. Each of the Company and its subsidiaries owns or is licensed to use all patents, patent applications, trademarks, trademark applications, trade names, service marks, copyrights, copyright applications, licenses, permits, inventions, discoveries, processes, scientific, technical, engineering and marketing data, object and source codes, know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures) and other similar rights and proprietary knowledge (collectively, "INTANGIBLES") necessary for the conduct of its business as now being conducted. To the best knowledge of the Company, neither the Company nor any subsidiary of the Company infringes or is in conflict with any right of any other person with respect to any Intangibles. Except as set forth on Schedule 3(j), neither the Company nor any of its subsidiaries has received written notice of any pending conflict with or infringement upon such third party Intangibles. Except as set forth on Schedule 3(j), the termination of the Company's ownership of, or right to use, any single Intangible would not result in a Material Adverse Effect on the Company. Neither the Company nor any of its subsidiaries has entered into any consent agreement, indemnification agreement, forbearance to sue or settlement agreement with respect to the validity of the Company's or its subsidiaries' ownership or right to use its Intangibles and, to the best knowledge of the Company, there is no reasonable basis for any such claim to be successful. The Intangibles are valid and enforceable and no registration relating thereto has lapsed, expired or been abandoned or canceled or is the subject of cancellation or other adversarial proceedings, and all applications therefor are pending and in good standing. The Company and its subsidiaries have complied, in all material respects, with their respective contractual obligations relating to the protection of the Intangibles used pursuant to licenses. To the best knowledge of the Company, no person is infringing on or violating the Intangibles owned or used by the Company or its subsidiaries. (k) Foreign Corrupt Practices. Neither the Company, nor any of its subsidiaries, nor any director, officer, agent, employee or other person acting on behalf of the Company or any subsidiary has, in the course of his actions for, or on behalf of, the Company, used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expenses relating to political activity; made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds; violated or is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977; or made any bribe, rebate, payoff, influence payment, kickback or other unlawful payment to any foreign or domestic government official or employee. (l) Disclosure. All information relating to or concerning the Company set forth in this Agreement or provided to any Purchaser pursuant to Section 2(d) hereof or otherwise in connection with the transactions contemplated hereby is true and correct in all material respects and the Company has not omitted to state any material fact necessary in order to make the statements made herein or therein, in light of the circumstances under which they were made, not misleading. (m) Acknowledgment Regarding Purchasers' Purchase of the Units. The Company acknowledges and agrees that none of the Purchasers is acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to this Agreement or the transactions contemplated hereby, the relationship between the Company and the Purchasers is "arms-length" and any statement made by any Purchaser or any of its representatives or agents in connection with this Agreement and the transactions contemplated hereby is merely incidental to such Purchaser's purchase of Securities and has not been relied upon by the Company, its officers or directors in any way. The Company further acknowledges that the Company's decision to enter into this Agreement has been based solely on an independent evaluation by the Company and its representatives. (n) Listing. The Company has secured the listing of the Conversion Shares and Warrant Shares upon each national securities exchange or automated quotation system upon which shares of Common Stock are currently listed (subject to official notice of issuance). (o) Form S-3 Eligibility. The Company is currently eligible to register the resale of its Common Stock on a registration statement on Form S-3 under the Securities Act. There exist no facts or circumstances that would prohibit or delay the preparation and filing of a registration statement on Form S-3 with respect to the Registrable Securities (as defined in the Registration Rights Agreement). The Company has no basis to believe that its past or present independent public auditors will withhold their consent to the inclusion, or incorporation by reference, of their audit opinion concerning the Company's financial statements which are included in the Registration Statement required to be filed pursuant to the Registration Rights Agreement. (p) No General Solicitation. Neither the Company nor any distributor participating on the Company's behalf in the transactions contemplated hereby (if any) nor any person acting for the Company, or any such distributor, has conducted any "general solicitation," as such term is defined in Regulation D, with respect to any of the Securities being offered hereby. (q) No Integrated Offering. Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has directly or indirectly made any offers or sales of any security or solicited any offers to buy any security under circumstances that would require registration of the Securities being offered hereby under the Securities Act or cause this offering of Securities to be integrated with any prior offering of securities of the Company for purposes of the Securities Act or any applicable stockholder approval provisions, including, without limitation, Rule 4350(i) of the NASD or any similar rule. (r) No Brokers. The Company has taken no action which would give rise to any claim by any person (including CIBC World Markets and UBS Warburg, both of whom have had financial advisory relationships with the Company) for brokerage commissions or finder's fees or for similar payments by any Purchaser relating to this Agreement or the transactions contemplated hereby. (s) Acknowledgment Regarding Securities. The number of Conversion Shares issuable upon conversion of the Preferred Shares may increase in certain circumstances. The Company's executive officers have studied and fully understand the nature of the Securities being sold hereunder. The Company acknowledges that its obligation to issue Conversion Shares upon conversion of the Preferred Shares in accordance with the Certificate of Designation is, other than as set forth in the Certificate of Designation, absolute and unconditional, regardless of the dilution that such issuance may have on the ownership interests of other stockholders and the availability of remedies provided for in the Transaction Documents relating to a failure or refusal to issue Conversion Shares. Taking the foregoing into account, the Company's Board of Directors has determined in its good faith business judgment that the issuance of the Preferred Shares and Warrants hereunder and the consummation of the other transactions contemplated hereby are in the best interests of the Company and its stockholders. The Company's Board of Directors and executive officers fully intend to honor their obligations hereunder to issue Conversion Shares upon conversion of the Preferred Shares regardless of the dilution that such issuance may have on the ownership interests of other stockholders and the availability of remedies provided for in the Transaction Documents relating to their failure or refusal to issue Conversion Shares. (t) Title. The Company and its subsidiaries have good and marketable title in fee simple to all real property and good and merchantable title to all personal property owned by them that is material to the business of the Company and its subsidiaries, in each case free and clear of all liens, encumbrances and defects except such as do not materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company and its subsidiaries. Any real property and facilities held under lease by the Company and its subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as are not material and do not materially interfere with the use made and proposed to be made of such property and buildings by the Company and its subsidiaries. (u) Tax Status. Except as set forth in the SEC Documents, the Company and each of its subsidiaries has made or filed all foreign, U.S. federal, state and local income and all other tax returns, reports and declarations required by any jurisdiction to which it is subject (unless and only to the extent that the Company and each of its subsidiaries has set aside on its books provisions reasonably adequate for the payment of all unpaid and unreported taxes) and has paid all taxes and other governmental assessments and charges that are material in amount, shown or determined to be due on such returns, reports and declarations, except those being contested in good faith and has set aside on its books provisions reasonably adequate for the payment of all taxes for periods subsequent to the periods to which such returns, reports or declarations apply. There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company know of no basis for any such claim. The Company has not executed a waiver with respect to any statute of limitations relating to the assessment or collection of any federal, state or local tax. None of the Company's tax returns is presently being audited by any taxing authority. (v) Key Employees. Each of the Company's directors, officers and any Key Employee (as defined below) is currently serving the Company in the capacity disclosed in the SEC Documents. No Key Employee, to the best of the knowledge of the Company and its subsidiaries, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any other contract or agreement or any restrictive covenant, and the continued employment of each Key Employee does not subject the Company or any of its subsidiaries to any liability with respect to any of the foregoing matters. No Key Employee has, to the knowledge of the Company and its subsidiaries, any intention to terminate or limit his employment with, or services to, the Company or any of its subsidiaries, nor, to the knowledge of the Company, is any such Key Employee subject to any constraints which would cause such employee to be unable to devote his full time and attention to such employment or services. "KEY EMPLOYEE" means the persons listed on Schedule 3(v) and any individual who assumes or performs any of the duties of a Key Employee. (w) Insurance.

The Company shall file with the SEC a Form D with respect to the Securities as required under Regulation D and provide a copy thereof to each Purchaser promptly after such filing. The Company shall, on or before the Closing Date, take such action as the Company shall reasonably determine is necessary to qualify the Securities for sale to each Purchaser pursuant to this Agreement under applicable securities or "blue sky" laws of the states of the United States or obtain exemption therefrom, and shall provide evidence of any such action so taken to each Purchaser on or prior to the Closing Date. Within four (4) trading days after the Closing Date, the Company shall file a Form 8-K concerning this Agreement and the transactions contemplated hereby, which Form 8-K shall attach this Agreement and its Exhibits as exhibits to such Form 8-K. (c) Reporting Status. So long as any Purchaser beneficially owns any of the Securities, the Company shall timely file (within applicable extension periods) all reports required to be filed with the SEC pursuant to the Exchange Act, and the Company shall not terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and regulations thereunder would permit such termination. In addition, the Company shall take all actions reasonably necessary to meet the "registrant eligibility" requirements set forth in the general instructions to Form S-3 or any successor form thereto, to continue to be eligible to register the resale of its Common Stock on a registration statement on Form S-3 under the Securities Act. (d) Use of Proceeds. The Company shall use the proceeds from the sale of the Preferred Shares and Warrants for general corporate purposes and working capital and such proceeds shall not be used to repay indebtedness (other than indebtedness incurred in the ordinary course of business), make acquisitions, or make payments to stockholders or affiliates of the Company. Subject to the use of proceeds as outlined above, the Company will invest the proceeds (i) in evidences of indebtedness issued or fully guaranteed by the United States of America and having a maturity of not more than one year from the date of acquisition; (ii) in certificates of deposit, notes, acceptances and repurchase agreements having a maturity of not more than one year from the date of acquisition issued by a bank organized in the United States having capital, surplus and undivided profits of at least $500,000,000; (iii) in the highest-rated commercial paper having a maturity of not more than one year from the date of acquisition; and (iv) in "Money Market" fund shares, or in money market accounts fully insured by the Federal Deposit Insurance Corporation and sponsored by banks and other financial institutions, provided that the investments consist principally of the types of investments described in clauses (i), (ii), or (iii) above. (e) Participation Right. Subject to the terms and conditions specified in this Section 4(e), for a period of one year after the date that the Registration Statement (as defined in the Registration Rights Agreement) the Company is required to file pursuant to Section 2(a) of the Registration Rights Agreement is declared effective, the Purchasers shall have a right to participate with respect to the issuance or possible issuance of (i) future equity or equity-linked securities, or (ii) debt which is convertible into equity or in which there is an equity component ("ADDITIONAL SECURITIES") on the same terms and conditions as offered by the Company to the other purchasers of such Additional Securities. Each time the Company proposes to offer any Additional Securities, the Company shall make an offering of such Additional Securities to each Purchaser in accordance with the following provisions: (i) the Company shall deliver a notice (the "NOTICE") to the Purchasers stating (i) its bona fide intention to offer such Additional Securities, (ii) the number of such Additional Securities to be offered, (iii) the price and terms, if any, upon which it proposes to offer such Additional Securities, and (iv) the anticipated closing date of the sale of such Additional Securities. (ii) by written notification received by the Company, within twenty (20) days after giving of the Notice, any Purchaser may elect to purchase or obtain, at the price and on the terms specified in the Notice, up to that portion of such Additional Securities which equals the proportion that the number of shares of Common Stock purchased by such Purchaser pursuant to the terms hereof bears to the total number of shares of Common Stock then outstanding (assuming in each case full conversion and exercise of all convertible or exercisable securities then outstanding). The Company shall promptly, in writing, inform each Purchaser which elects to purchase all of the Additional Shares available to it ("FULLY-EXERCISING PURCHASER") of any other Purchaser's failure to do likewise. During the five-day period commencing after such information is given, each Fully-Exercising Purchaser shall be entitled to obtain that portion of the Additional Securities for which the Purchasers were entitled to subscribe but which were not subscribed for by the Purchasers which is equal to the proportion that the number of shares of Common Stock held by such Fully-Exercising Purchaser bears to the total number of shares of Common Stock held by all Fully-Exercising Purchasers who wish to purchase some of the unsubscribed shares; (iii) if all Additional Securities which the Purchasers are entitled to obtain pursuant to subsection 4(e)(ii) are not elected to be obtained as provided in subsection 4(e)(ii) hereof, the Company may, during the 75-day period following the expiration of the period provided in subsection 4(e)(ii) hereof, offer the remaining unsubscribed portion of such Additional Securities to any person or persons at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Notice. If the Company does not consummate the sale of such Additional Securities within such period, the right provided hereunder shall be deemed to be revived and such Additional Securities shall not be offered or sold unless first reoffered to the Purchasers in accordance herewith; (iv) the participation right in this Section 4(e) shall not be applicable to (i) the issuance or sale of shares of Common Stock (or options therefor) to employees, officers, directors, or consultants of the Company for the primary purpose of soliciting or retaining their employment or service pursuant to a stock option plan (or similar equity incentive plan) approved by the Board of Directors, (ii) the issuance of securities in connection with a bona fide underwritten public offering at an offering price per share (prior to underwriter's commissions and discounts) of not less than $4.56 per share (as adjusted to reflect any stock dividends, distributions, combinations, reclassifications and other similar transactions effected by the Corporation in respect to its Common Stock) that results in total proceeds to the Company of at least $40,000,000, (iii) the issuance or sale of the Preferred Shares, (iv) the issuance of securities in connection with mergers, acquisitions, strategic business partnerships or joint ventures (including, without limitation, such transactions with major pharmaceutical labs or life sciences companies), the primary purpose of which, in the reasonable judgment of the Board of Directors, is not to raise additional capital, (v) the issuance of securities pursuant to any equipment financing from a bank or similar financial or lending institution approved by the Board of Directors, or (vi) any issuance of securities as to which the holders of a majority of the then outstanding Preferred Shares shall have executed a written waiver of the rights contained in this Section 4(e). (v) the participation right set forth in this Section 4(e) may not be assigned or transferred, except that such right is assignable by each Purchaser to any wholly-owned subsidiary or parent of, or to any corporation or entity that is, within the meaning of the Securities Act, controlling, controlled by or under common control with, any such Purchaser. (f) Expenses. The Company shall pay to SDS Capital Partners ("SDS CAPITAL") at the Closing, reimbursement for the out-of-pocket expenses reasonably incurred by SDS Capital's advisors in connection with the negotiation, preparation, execution and delivery of this Agreement and the other agreements to be executed in connection herewith, including, without limitation, SDS Capital's advisors' reasonable due diligence and attorneys' fees and expenses (the "EXPENSES"); provided, however, that in lieu of such payment SDS Capital (or its affiliates) shall be permitted to deduct all Expenses from the purchase price payable by SDS Capital (or its affiliates) hereunder. In addition, from time to time thereafter, upon SDS Capital's written request, the Company shall pay to SDS Capital such additional Expenses, if any, not covered by such payment, in each case to the extent reasonably incurred by SDS Capital's agents prior to the Closing in connection with the negotiation, preparation, execution and delivery of this Agreement. (g) Financial Information. The Company shall send the following reports to each Purchaser until such Purchaser transfers, assigns or sells all of its Securities: within ten (10) days after the filing with the SEC, a copy of its Annual Report on Form 10-K, its Quarterly Reports on Form 10-Q, its proxy statements and any Current Reports on Form 8-K. To the extent that any of the foregoing documents is available under the SEC's EDGAR filing system, such documents shall be deemed to have been delivered to each of the Purchasers. (h) Reservation of Shares. The Company shall at all times have authorized and reserved for the purpose of issuance a sufficient number of shares of Common Stock to provide for the full conversion of the outstanding Preferred Shares and issuance of the Conversion Shares in connection therewith, the full exercise of the Warrants and the issuance of the Warrant Shares in connection therewith and in each case to the extent required by the Certificate of Designation and the Warrants. (i) Listing. The Company shall have filed an application for the listing of the Conversion Shares and the Warrant Shares on the NNM on or before the Closing. From the time that such application has been approved and thereafter, the Company shall maintain, so long as any Purchaser (or any of their affiliates) own any Securities, the listing of all Conversion Shares and Warrant Shares from time to time issuable upon conversion of the Preferred Shares and exercise of the Warrants on each national securities exchange or automated quotation system on which shares of Common Stock are currently listed. The Company will use its best efforts to continue the listing and trading of its Common Stock on the NNM, the New York Stock Exchange ("NYSE"), the American Stock Exchange ("AMEX") or the Nasdaq SmallCap Market (the "SMALLCAP") and will comply in all material respects with the reporting, filing and other obligations under the bylaws or rules of the NASD and such exchanges, as applicable. The Company shall promptly provide to each holder of Preferred Shares and/or Warrants copies of any notices it receives regarding the continued eligibility of the Common Stock for trading on the NNM or, if applicable, any securities exchange or automated quotation system on which securities of the same class or series issued by the Company are then listed or quoted, if any. (j) Corporate Existence. So long as a Purchaser beneficially owns any Securities, the Company shall maintain its corporate existence, and in the event of a merger, consolidation or sale of all or substantially all of the Company's assets, the Company shall ensure that the surviving or successor entity in such transaction (i) assumes the Company's obligations hereunder and under the Certificate of Designation, the Warrants and the agreements and instruments entered into in connection herewith regardless of whether or not the Company would have had a sufficient number of shares of Common Stock authorized and available for issuance in order to effect the conversion of all Preferred Shares and exercise in full of all Warrants outstanding as of the date of such transaction and (ii) is a publicly traded corporation whose common stock is listed for trading on the NNM, SmallCap, NYSE or AMEX. Notwithstanding the foregoing, the Company covenants and agrees that it will not engage in any merger, consolidation or sale of all or substantially all of its assets at any time prior to the effectiveness of the Registration Statement required to be filed pursuant to the Registration Rights Agreement without (A) providing each Purchaser with written notice of such transaction at least 60 days prior to the consummation of such transaction and (B) obtaining the written consent of the Purchasers holding a majority-in-interest of the then outstanding Preferred Shares on or before the 10th day after the delivery of such notice by the Company. (k) No Integrated Offerings. The Company shall not make any offers or sales of any security (other than the Securities) under circumstances that would require registration of the Securities being offered or sold hereunder under the Securities Act or cause this offering of the Securities to be integrated with any other offering of securities by the Company for purposes of any stockholder approval provision applicable to the Company or its securities. (l) Legal Compliance. The Company shall conduct its business and the business of its subsidiaries in compliance with all laws, ordinances or regulations of governmental entities applicable to such businesses, except where the failure to do so would not have a Material Adverse Effect. (m) Redemptions and Dividends. So long as any Purchaser beneficially owns any Preferred Shares, the Company shall not, without first obtaining the written approval of such Purchaser, repurchase, redeem, or declare or pay any cash dividend or distribution on, any shares of capital stock of the Company. (n) Information. The Company will furnish to each Purchaser, so long as it holds any Preferred Shares: (i) concurrently with the filing with the SEC of its annual reports on Form 10-K, a certificate of the President, a Vice President or a senior financial officer of the Company stating that, based upon such examination or investigation and review of this Agreement as in the opinion of the signer is necessary to enable the signer to express an informed opinion with respect thereto, neither the Company nor any of its subsidiaries is or has during such period been in default in the performance or observance of any of the terms, covenants or conditions hereof, or, if the Company or any of its subsidiaries shall be or shall have been in default, specifying all such defaults, and the nature and period of existence thereof, and what action the Company or such subsidiary has taken, is taking or proposes to take with respect thereto; and (ii) the information the Company must deliver to any holder or to any prospective transferee of Securities in order to permit the sale or other transfer of such Securities pursuant to Rule 144A of the SEC or any similar rule then in effect. The Company will keep at its principal executive office a true copy of this Agreement (as at the time in effect), and cause the same to be available for inspection at such office during normal business hours by any holder of Securities or any prospective transferee of Securities designated by a holder thereof. (o) Inspection of Properties and Books. So long as any Purchaser shall hold any Securities, such Purchaser and its representatives and agents (collectively, the "INSPECTORS") shall have the right, at such Purchaser's expense, to visit and inspect any of the properties of the Company and of its subsidiaries, to examine the books of account and records of the Company and of its subsidiaries, to make or be provided with copies and extracts therefrom, to discuss the affairs, finances and accounts of the Company and of its subsidiaries with, and to be advised as to the same by, its and their officers, employees and independent public accountants (and by this provision the Company authorizes such accountants to discuss such affairs, finances and accounts, whether or not a representative of the Company is present) all at such reasonable times and intervals and to such reasonable extent as such Purchaser may desire; provided, however, that each Inspector shall hold in confidence and shall not make any disclosure (except to such Purchaser) of any such information which the Company determines in good faith to be confidential, and of which determination the Inspectors are so notified, unless (a) the disclosure of such information is necessary to avoid or correct a misstatement or omission in any Registration Statement filed pursuant to the Registration Rights Agreement, (b) the release of such information is ordered pursuant to a subpoena or other order from a court or government body of competent jurisdiction, or (c) such information has been made generally available to the public other than by disclosure in violation of this or any other agreement. The Company shall not be required to disclose any confidential information to any Inspector until and unless such Inspector shall have entered into confidentiality agreements (in form and substance satisfactory to the Company) with the Company with respect thereto, substantially in the form of this Section 4(o). Each Purchaser agrees that it shall, upon learning that disclosure of such information is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Company and allow the Company, at its expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the information deemed confidential. Notwithstanding the foregoing, the Company shall be permitted to withhold from disclosure under this paragraph any material protected by attorney-client privilege. (p) Waivers and Consents. Prior to the effectiveness any Registration Statement filed in accordance with Section 2(a) of the Registration Rights Agreement, the Company shall have obtained proper waivers from the stockholders and warrant holders referred to on Schedule 3(f) of the Schedule of Exceptions to this Agreement.

(r) Confidential Agreement. Each Purchaser will hold in confidence all information concerning this Agreement and the placement of shares hereunder until the earlier of such time as (i) the Company has made a public announcement concerning the Agreement and the placement of shares hereunder or (ii) this Agreement is terminated. 5.

The representations and warranties of the Company and the agreements and covenants set forth in Sections 3, 4, 5 and 8 hereof shall survive the Closing notwithstanding any due diligence investigation conducted by or on behalf of any Purchaser. Moreover, none of the representations and warranties made by the Company herein shall act as a waiver of any rights or remedies any Purchaser may have under applicable U.S. federal or state securities laws. (j) Publicity. The Company and each Purchaser shall have the right to approve before issuance any press releases, SEC or NASD filings, or any other public statements with respect to the transactions contemplated hereby; provided, however, that the Company shall be entitled, without the prior approval of the Purchasers, to make any press release or SEC or NASD filings with respect to such transactions as is required by applicable law and regulations (although the Purchasers shall be consulted by the Company in connection with any such press release and filing prior to its release and shall be provided with a copy thereof). (k) Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as the other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

In the event that the Closing shall not have occurred on or before March 31, 2002, unless the parties agree otherwise, this Agreement shall terminate at the close of business on such date. Notwithstanding any termination of this Agreement, any party not in breach of this Agreement shall preserve all rights and remedies it may have against another party hereto for a breach of this Agreement prior to or relating to the termination hereof. (m) Joint Participation in Drafting. Each party to this Agreement has participated in the negotiation and drafting of this Agreement, the Certificate of Designation, the Warrants and the Registration Rights Agreement. As such, the language used herein and therein shall be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction will be applied against any party to this Agreement. (n) Equitable Relief. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to each Purchaser by vitiating the intent and purpose of the transactions contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations hereunder (including, but not limited to, its obligations pursuant to Section 5 hereof) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Agreement (including, but not limited to, its obligations pursuant to Section 5 hereof), that each Purchaser shall be entitled, in addition to all other available remedies, to an injunction restraining any breach and requiring immediate issuance and transfer of the Securities, without the necessity of showing economic loss and without any bond or other security being required. (o) Additional Acknowledgement. Each Purchaser acknowledges that it has independently evaluated the merits of the transactions contemplated by this Agreement, the Certificate of Designation, the Registration Rights Agreement and the Warrants, that it has independently determined to enter into the transactions contemplated hereby and thereby, that it is not relying on any advice from or evaluation by any other Purchaser, and that it is not acting in concert with any other Purchaser in making its purchase of securities hereunder. The Purchasers and, to its knowledge, the Company agree that the Purchasers have not taken any actions that would deem such Purchasers to be members of a "group" for purposes of Section 13(d) of the Exchange Act. (p) Indemnification by Company.
