ARTICLE II REPRESENTATIONS AND WARRANTIES Section 2.1 Representation and Warranties of the Company. The Company hereby makes the following representations and warranties to the Purchasers, except as set forth in the Company's disclosure schedules delivered with this Agreement: (a) Organization, Good Standing and Power. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has the requisite corporate power to own, lease and operate its properties and assets and to conduct its business as it is now being conducted and to enter into this Agreement and to perform its obligations hereunder. The Company does not have any subsidiaries or own securities of any kind in any other entity, except as set forth in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2000 (the "Form 10-K"), the Company's Quarterly Reports on Form 10-Q for the fiscal period ended March 31, 2001, June 30, 2001 and September 30, 2001, and all of the Company's other filings with the Securities and Exchange Commission (the "SEC") prior to the date hereof (collectively, the "Commission Documents"). The Company and each subsidiary is duly qualified as a foreign corporation to do business and is in good standing in every jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary except for any jurisdiction(s) (alone or in the aggregate) in which the failure to be so qualified will not have a Material Adverse Effect (as defined hereinafter) on the Company's financial condition. For the purposes of this Agreement, "Material Adverse Effect" means any adverse effect on the business, operations, properties, prospects, assets or financial condition of the Company or its subsidiaries and which is material to such entity or other entities controlling or controlled by such entity or which is likely to 2 materially hinder the performance by the Company of its obligation hereunder and under the other Transaction Documents (as defined in Section 2.1(b) hereof). (b) Authorization; Enforcement. The Company has the requisite corporate power and authority to enter into and perform its obligations under this Agreement, the Registration Rights Agreement attached as Exhibit C hereto (the "Registration Rights Agreement"), the Transfer Agent Instructions (as defined in Section 3.7 hereof) and the Warrants (collectively, the "Transaction Documents") and to issue and sell the Shares in accordance with the terms hereof and the Warrants. The execution, delivery and performance of each of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby have been duly and validly authorized by all necessary corporate action, and no further consent or authorization of the Company or the Company's board of directors or its stockholders is required. This Agreement has been duly executed and delivered by the Company. The Registration Rights Agreement will have been duly executed and delivered by the Company on or before the Closing Date. Each of the Transaction Documents constitutes, or shall constitute when executed and delivered, a valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation, conservatorship, receivership or similar laws relating to, or affecting generally the enforcement of, creditor's rights and remedies or by other equitable principles of general application. (c) Capitalization. The authorized capital stock of the Company and the shares thereof issued and outstanding as of the date hereof are set forth on Schedule 2.1(c) hereto. All of the outstanding shares of the Company's Common Stock have been duly and validly authorized. Except as set forth in this Agreement and the Registration Rights Agreement and as set forth in the Commission Documents or on Schedule 2.1(c) hereto, no shares of Common Stock or any other securities issued by the Company are entitled to preemptive rights and there are no outstanding options, warrants, scrip, rights to subscribe to, call or commitments of any character whatsoever relating to, or securities or rights convertible into, any shares of capital stock of the Company. Furthermore, except as set forth in this Agreement and the Registration Rights Agreement and as set forth in the Commission Documents or on Schedule 2.1(c), there are no contracts, commitments, understandings, or arrangements by which the Company is or may become bound to issue additional shares of the capital stock of the Company or options, securities or rights convertible into shares of capital stock of the Company. Except for customary transfer restrictions contained in agreements entered into by the Company in order to sell restricted securities or as provided on the Commission Documents or Schedule 2.1(c) hereto, the Company is not a party to or bound by any agreement or understanding granting anti-dilution rights to any person with respect to any of its equity or debt securities. The Company is not a party to, and it has no knowledge of, any agreement or understanding restricting the voting or transfer of any shares of the capital stock of the Company. Except as set forth on the Commission Documents or Schedule 2.1(c) hereto, the offer and sale of all capital stock, convertible securities, rights, warrants, or options of the Company issued prior to the Closing complied with all applicable federal and state securities laws, and no holder of such securities has a right of rescission or claim for damages with respect thereto which could have a Material Adverse Effect. The Company has furnished or made available to the Purchasers true and 3 correct copies of the Company's Articles of Incorporation as in effect on the date hereof (the "Articles"), and the Company's Bylaws as in effect on the date hereof (the "Bylaws"). (d) Issuance of Securities. The Shares to be issued at the Closing have been duly authorized by all necessary corporate action and, when paid for or issued in accordance with the terms hereof, the Shares shall be validly issued and outstanding, fully paid and nonassessable, and free from preemptive rights, taxes upon issuance, liens and similar charges caused by the Company and entitled to all applicable rights and preferences set forth in the Articles. When the Warrant Shares are issued in accordance with the terms of this Agreement and as set forth in the Warrants, such shares will be duly authorized by all necessary corporate action and validly issued and outstanding, fully paid and non-assessable, and free from preemptive rights, taxes upon issuance, liens and other similar charges caused by the Company, and the holders shall be entitled to all rights accorded to a holder of Common Stock. (e) No Conflicts. Except as set forth in the Commission Documents or Schedule 2.1(e) attached hereto, the execution, delivery and performance of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated herein and therein do not and will not (i) violate any provision of the Company's Articles or Bylaws, (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, mortgage, deed of trust, indenture, note, bond, license, lease agreement, instrument or obligation to which the Company is a party or by which any of its respective properties or assets are bound, (iii) create or impose a lien, mortgage, security interest, charge or encumbrance of any nature whatsoever on any property of the Company under any agreement or any commitment to which the Company is a party or by which the Company is bound or by which any of its respective properties or assets are bound, or (iv) result in a violation of any federal, state, local or foreign statute, rule, regulation, order, judgment or decree (including federal and state securities laws and regulations) applicable to the Company or any of its subsidiaries or by which any property or asset of the Company or any of its subsidiaries are bound or affected, except, in all cases other than violations pursuant to clause (i) above, for such conflicts, defaults, terminations, amendments, acceleration, cancellations and violations as would not, individually or in the aggregate, have a Material Adverse Effect. The business of the Company and its subsidiaries is not being conducted in violation of any laws, ordinances or regulations of any governmental entity, except for possible violations which singularly or in the aggregate do not and will not have a Material Adverse Effect. The Company is not required under federal, state or local law, rule or regulation to obtain any consent, authorization or order of, or make any filing or registration with, any court or governmental agency in order for it to execute, deliver or perform any of its obligations under the Transaction Documents, or issue and sell the Shares and the Warrant Shares in accordance with the terms hereof or thereof (other than any filings which may be required to be made by the Company with the Commission or state securities administrators subsequent to a Closing, and any registration statement which may be filed pursuant hereto); provided that, for purposes of the representation made in this sentence, the Company is assuming and relying upon the accuracy of the relevant representations and agreements of the Purchasers herein. 4 (f) Commission Documents, Financial Statements. The Company has provided to the Purchasers prior to the date hereof copies of the Form 10-K and Forms 10-Q for the fiscal periods ended March 31, 2001, June 30, 2001 and September 30, 2001, respectively. The Company has not provided to the Purchasers any material non-public information or other information which, according to applicable law, rule or regulation, should have been disclosed publicly by the Company but which has not been so disclosed, other than with respect to the transactions contemplated by this Agreement. The financial statements of the Company furnished to the Purchasers comply as to form in all material respects with applicable accounting requirements and the published rules and regulations of the Commission or other applicable rules and regulations with respect thereto.

(g) Subsidiaries. The Commission Documents or Schedule 2.1(g) hereto sets forth each subsidiary of the Company showing the jurisdiction of its incorporation or organization and showing the percentage of the Company's ownership of the outstanding stock or other interests of such subsidiary. For the purposes of this Agreement, "subsidiary" shall mean any corporation or other entity of which at least a majority of the securities or other ownership interest having ordinary voting power (absolutely or contingently) for the election of directors or other persons performing similar functions are at the time owned directly or indirectly by the Company and/or any of its other subsidiaries. All of the outstanding shares of capital stock of each subsidiary have been duly authorized and validly issued, and are fully paid and non-assessable.

Except as set forth in the Commission Documents or on Schedule 2.1(q) hereto, or as previously disclosed by the Company to Purchasers, neither the Company nor any subsidiary is a party to any written or oral contract, instrument, agreement, commitment, obligation, plan or arrangement, a copy of which would be required to be filed with the Commission as an exhibit to a registration statement on Form S-3 or applicable form (collectively, "Material Agreements") if the Company or any subsidiary were registering securities under the Securities Act. Except as set forth in the Commission Documents or on Schedule 2.1(q) hereto, the Company and each of its subsidiaries has in all material respects performed all the obligations required to be performed by them to date under the foregoing agreements, have received no notice of default and, to the best of the Company's knowledge are not in default under any Material Agreement now in effect, the result of which could cause a Material Adverse Effect. No written or oral contract, instrument, agreement, commitment, obligation, plan or arrangement of the Company or of any subsidiary limits or shall limit the payment of dividends on the Company's Common Stock. (r) Securities Act of 1933. The Company has complied and will comply with all applicable federal and state securities laws in connection with the offer, issuance and sale of the Shares and the Warrants hereunder. Neither the Company nor anyone acting on its behalf, directly or indirectly, has or will sell, offer to sell or solicit offers to buy any of the Shares, or similar securities to, or solicit offers with respect thereto from, or enter into any preliminary conversations or negotiations relating thereto with, any person, or has taken or will take any action so as to bring the issuance and sale of any of the Shares under the registration provisions 7 of the Securities Act and any other applicable federal and state securities laws. Assuming the representations set forth in Section 2.2 hereof are true, the Securities may be issued without registration under the Securities Act of 1933. Neither the Company nor any of its affiliates, nor any person acting on its or their behalf, has engaged in any form of general solicitation or general advertising (within the meaning of Regulation D under the Securities Act) in connection with any of the Shares. (s) Governmental Approvals. Except as set forth in the Commission Documents or on Schedule 2.1(s) hereto, and except for the filing of any notice prior or subsequent to the Closing that may be required under applicable state or federal securities laws (which if required, shall be filed on a timely basis), including, but not limited to, the filing of a registration statement or statements pursuant to the Registration Rights Agreement, no authorization, consent, approval, license exemption of, filing or registration with any court or governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, is or will be necessary for, or in connection with, the execution or delivery of the Shares, or for the performance by the Company of its obligations under the Transaction Documents.

Except as set forth in the Commission Documents or on Schedule 2.1(t) hereto, neither the Company nor any subsidiary has any employment contract, agreement regarding proprietary information, non-competition agreement, non-solicitation agreement, confidentiality agreement, or any other similar contract or restrictive covenant, relating to the right of any officer, employee or consultant to be employed or engaged by the Company or such subsidiary. Since September 30, 2001, no officer, consultant or key employee of the Company or any subsidiary whose termination, either individually or in the aggregate, could have a Material Adverse Effect, has terminated or, to the knowledge of the Company, has any present intention of terminating his or her employment or engagement with the Company or any subsidiary.

(w) ERISA. No liability to the Pension Benefit Guaranty Corporation has been incurred with respect to any Plan by the Company or any of its subsidiaries which is or would be materially adverse to the Company and its subsidiaries. The execution, delivery and performance of this Agreement and the other Transaction Documents and the issue and sale of the Shares and the Warrants will not involve any transaction which is subject to the prohibitions of Section 406 of ERISA or in connection with which a tax could be imposed pursuant to Section 8 4975 of the Internal Revenue Code of 1986, as amended, provided that, if any of the Purchasers, or any person or entity that owns a beneficial interest in any of the Purchasers, is an "employee pension benefit plan" (within the meaning of Section 3(2) of ERISA) with respect to which the Company is a "party in interest" (within the meaning of Section 3(14) of ERISA), the requirements of Sections 407(d)(5) and 408(e) of ERISA, if applicable, are met. As used in this Section 2.1(z), the term "Plan" shall mean an "employee pension benefit plan" (as defined in Section 3 of ERISA) which is or has been established or maintained, or to which contributions are or have been made, by the Company or any subsidiary or by any trade or business, whether or not incorporated, which, together with the Company or any subsidiary, is under common control, as described in Section 414(b) or (c) of the Code. (x) No Integrated Offering. To the best of the Company's knowledge, 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 any of the Securities under the 1933 Act or cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of the 1933 Act or any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the Securities of the Company are listed or designated, nor will the Company or any of its subsidiaries take any actions or steps that would require registration of any of the Securities under the 1933 Act or cause the offering of the Securities to be integrated with other offerings. (y) Eligibility. The Company is currently eligible to register the resale of the Securities on a registration statement on Form S-3 under the 1933 Act.

(a) The Company shall notify the Commission in accordance with their rules and regulations of the transactions contemplated by any of the Transaction Documents, as may be required, and shall take all other necessary action and proceedings as may be required and permitted by applicable law, rule and regulation, for the legal and valid issuance of the Shares and the Warrant Shares to the Purchasers or subsequent holders and will take no action to cause integration under the 1933 Securities Act or the rules of Nasdaq.

Section 3.4 Amendments. The Company shall not amend or waive any provision of the Articles or Bylaws of the Company, or the Registration Rights Agreement in any way that would adversely affect the dividend rights, exercise rights, voting rights or redemption rights of the holders of the Shares, the Warrants or the Warrant Shares. 12 Section 3.5 Other Agreements. The Company shall not enter into any agreement in which the terms of such agreement would restrict or impair the right or ability to perform of the Company or any subsidiary under any Transaction Document. Section 3.6 Reservation of Shares.

Section 3.7 Transfer Agent Instructions.

Prior to registration of the Shares and the Warrant Shares under the Securities Act, all such certificates shall bear the restrictive legend specified in Section 5.1 of this Agreement. The Company warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 3.7 will be given by the Company to its transfer agent and that the Shares and the Warrant Shares shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the Registration Rights Agreement.

The Company agrees to reissue certificates representing the Shares, Warrants or Warrant Shares, without the legend set forth above if at such time, prior to making any transfer of any Shares, Warrants or Warrant Shares such holder thereof shall give written notice to the Company describing the manner and terms of such transfer and removal as the Company may reasonably request and such holder otherwise complies with the terms of the Transaction Documents. The legend set forth above shall be removed and the Company shall issue a certificate without such legend to the holder of any Shares, Warrants or Warrant Shares upon which it is stamped if, unless otherwise required by federal or state securities laws, (a) the sale of such Shares, Warrants or Warrant Shares is registered under the Securities Act (including registration pursuant to Rule 416 thereunder) as contemplated by the Registration Rights Agreement (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 sale or transfer of such Shares, Warrants or Warrant Shares may be made without registration under the Securities Act; or (c) such holder provides the Company with reasonable assurances that such Shares, Warrants or Warrant Shares 16 can be sold under Rule 144(k).

In the event the above legend is removed from any Shares, Warrant or Warrant Shares and the effectiveness of a registration statement covering such Shares, Warrants or Warrant Shares is suspended or the Company determines that a supplement or amendment thereto is required by applicable securities laws, then upon reasonable advance notice to the Purchasers the Company may require that the above legend be placed on any such Shares, Warrants or Warrant Shares that cannot then be sold pursuant to an effective registration statement, under an exemption from the registration requirements of the Securities Act or under Rule 144(k) and the Purchasers shall cooperate in the replacement of such legend. Such legend shall thereafter be removed when such Shares, Warrants or Warrant Shares may again be sold pursuant to an effective registration statement, under an exemption from the registration requirements of the Securities Act or under Rule 144(k). The restrictions on transfer contained in Section 5.1 shall be in addition to, and not by way of limitation of, any other restrictions on transfer contained in any other section of this Agreement.

The Company agrees to indemnify and hold harmless the Purchasers (and its directors, officers, affiliates, agents, successors and assigns) from and against any and all actual losses, liabilities, deficiencies, costs, damages and reasonable expenses (including, without limitation, reasonable attorney's fees, charges and disbursements) incurred by the Purchasers as a result of any breach of the covenants, representations and warranties made by the Company herein. Each of the Purchasers agrees, severally and not jointly, to indemnify and hold harmless the Company and its directors, officers, affiliates, agents, successors and assigns from and against any and all actual losses, liabilities, deficiencies, costs, damages and reasonable expenses (including, without limitation, reasonable attorneys' fees, charges and disbursements) incurred by the Company as a result of any false representation or warranty or any breach of the covenants made by such Purchaser herein, provided, however, such Purchaser's indemnification obligations shall not exceed the Purchase Price. Section 6.2 Indemnification Procedure. Any party entitled to indemnification under this Article VI (an "indemnified party") will give written notice to the indemnifying party of any matters giving rise to a claim for indemnification; provided, that the failure of any party entitled to indemnification hereunder to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Article VII, except to the extent that the indemnifying party is actually materially prejudiced by such failure to give notice. In case any action, proceeding or claim is brought against an indemnified party in respect of which indemnification is sought hereunder, the indemnifying party shall be entitled to participate in, unless in the reasonable judgment of the indemnified party a conflict of interest between it and the indemnifying party may exist with respect of such action, an action, a proceeding or a claim, to assume the defense 17 thereof with counsel reasonably satisfactory to the indemnified party. In the event that the indemnifying party advises an indemnified party that it will contest such a claim for indemnification hereunder, or fails, within thirty (30) days of receipt of any indemnification notice to notify, in writing, such person of its election to defend, settle or compromise, at its sole cost and expense, any action, proceeding or claim (or discontinues its defense at any time after it commences such defense), then the indemnified party may, at its option, defend, settle or otherwise compromise or pay such action or claim. In any event, unless and until the indemnifying party elects in writing to assume and does so assume the defense of any such claim, proceeding or action, the indemnified party's costs and expenses arising out of the defense, settlement or compromise of any such action, claim or proceeding shall be losses subject to indemnification hereunder. The indemnified party shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the indemnified party which relates to such action or claim. The indemnifying party shall keep the indemnified party fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. If the indemnifying party elects to defend any such action or claim, then the indemnified party shall be entitled to participate in such defense with counsel of its choice at its sole cost and expense, unless in the reasonable judgment of the indemnified party a conflict of interest between it and the indemnifying party may exist with respect to such action or claim. The indemnifying party shall not be liable for any settlement of any action, claim or proceeding effected without its prior written consent. Notwithstanding anything in this Article VI to the contrary, the indemnifying party shall not, without the indemnified party's prior written consent (which consent shall not be unreasonable withheld), settle or compromise any claim or consent to entry of any judgment in respect thereof which imposes any future obligation on the indemnified party or which does not include, as an unconditional term thereof, the giving by the claimant or the plaintiff to the indemnified party of a release from all liability in respect of such claim. The indemnification required by this Article VI shall be made by periodic payments of the amount thereof during the course of investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred, so long as the indemnified party irrevocably agrees to refund such moneys if it is ultimately determined by a court of competent jurisdiction that such party was not entitled to indemnification. The indemnity agreements contained herein shall be in addition to (a) any cause of action or similar rights of the indemnified party against the indemnifying party or others and (b) any liabilities the indemnifying party may be subject to pursuant to the law.
