2.2 The Company may enter into the same form of Stock Purchase Agreement, including these Terms and Conditions, with certain other investors (the “Other Investors”) and expects to complete sales of Shares to them. (The Investor and the Other Investors are hereinafter sometimes collectively referred to as the “Investors,” and the Stock Purchase Agreement to which these Terms and Conditions are attached and the Stock Purchase Agreements (including attached Terms and Conditions) executed by the Other Investors are hereinafter sometimes collectively referred to as the “Agreements.”) The Company may accept executed Agreements from Investors for the purchase of Shares commencing upon the date on which the Company provides the Investors with the proposed purchase price per Share and concluding upon the date (the “Subscription Date”) on which the Company has (i) executed Agreements with Investors for the purchase of at least 2,045,453 Shares, and (ii) notified Xxxxx Fargo Securities, LLC, in its capacity as placement agent for this transaction, in writing that it is no longer accepting additional Agreements from Investors for the purchase of Shares.

Nothing contained herein, and no action taken by any Investor hereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby, provided that such obligations or the transactions contemplated hereby may be modified, amended or waived in accordance with Section 9 below. Each Investor shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement (provided, that such rights may be modified, amended or waived in accordance with Section 9 below), and it shall not be necessary for any Other Investor to be joined as an additional party in any proceeding for such purpose.

3. Delivery of the Shares at Closing.

At the Closing, the Company shall deliver to the Investor one or more stock certificates representing the number of Shares set forth in Section 3 of the Stock Purchase Agreement, each such certificate to be registered in the name of the Investor or, if so indicated on the signature page of the Stock Purchase Agreement, in the name of a nominee designated by the Investor.

4. Representations, Warranties and Covenants of the Company. The Company hereby represents and warrants to, and covenants with, the Investor, as follows:

-2-

4.1 Organization. The Company is duly organized and validly existing in good standing under the laws of the jurisdiction of its organization. Each of the Company and its Subsidiaries (as defined in Rule 405 under the Securities Act) has full power and authority to own, operate and occupy its properties and to conduct its business as presently conducted and as described in the documents filed by the Company under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), since December 31, 2001 through the date hereof, including, without limitation, its most recent report on Form 10-Q for the quarter ended September 30, 2002 (the “Exchange Act Documents”) and is registered or qualified to do business and in good standing in each jurisdiction in which the nature of the business conducted by it or the location of the properties owned or leased by it requires such qualification and where the failure to be so qualified would have a material adverse effect upon the condition (financial or otherwise), earnings, business or business prospects (such business prospects being as described in the Exchange Act Documents and in any press release issued by the Company since September 30, 2002 (collectively, the “Press Releases”)), properties or operations of the Company and its Subsidiaries, considered as one enterprise (a “Material Adverse Effect”), and no proceeding has been instituted in any such jurisdiction, revoking, limiting or curtailing, or seeking to revoke, limit or curtail, such power and authority or qualification.

4.2 Due Authorization and Valid Issuance. Assuming the correctness of the representations and warranties of the Investors set forth in the Agreements, (a) the Company has all requisite power and authority to execute, deliver and perform its obligations under the Agreements, and the Agreements have been duly authorized and validly executed and delivered by the Company and constitute legal, valid and binding agreements of the Company enforceable against the Company in accordance with their terms, except as rights to indemnity and contribution may be limited by state or federal securities laws or the public policy underlying such laws, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and except as enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), and (b) the Shares being purchased by the Investor hereunder will, upon issuance and payment therefor pursuant to the terms hereof, be duly authorized, validly issued, fully-paid and nonassessable.

4.3 Non-Contravention. The execution and delivery of the Agreements, the issuance and sale of the Shares under the Agreements, the fulfillment of the terms of the Agreements and the consummation of the transactions contemplated thereby will not (A) conflict with or constitute a violation of, or default (with the passage of time or otherwise) under, (i) any contract, agreement or other instrument filed or incorporated by reference as an exhibit to any of the Exchange Act Documents (any such contract, agreement or instrument, an “Exchange Act Exhibit”), (ii) the charter, by-laws or other organizational documents of the Company or any Subsidiary, or (iii) assuming the correctness of the representations and warranties of the Investors set forth in the Agreements, any law, administrative regulation, ordinance or order of any court or governmental agency, arbitration panel or authority applicable to the Company or any Subsidiary or their respective properties, except in the case of clauses (i) and (iii) for any such conflicts, violations or defaults which are not reasonably likely to have a Material Adverse Effect or (B) result in the creation or imposition of any lien, encumbrance, claim, security interest or restriction whatsoever upon any of the material properties or assets of the Company or any Subsidiary or an acceleration of indebtedness pursuant to any obligation, agreement or condition contained in any Exchange Act Exhibit. Assuming the correctness of the representations and warranties of the Investors set forth in the Agreements, no consent, approval, authorization or other order of, or registration, qualification or filing with, any regulatory body, administrative agency, or other governmental body in the United States or any other person is required for the execution and delivery of the Agreements and the valid issuance and sale of the Shares to be sold pursuant to the Agreements, other than such as have been made or obtained, and except for any post-closing securities filings or notifications required to be made under federal or state securities laws.

4.4 Capitalization. The capitalization of the Company as of September 30, 2002 is as set forth in the most recent applicable Exchange Act Documents, increased as set forth in the next sentence. The Company has not issued any capital stock since that date other than pursuant to (i) employee benefit plans disclosed in the Exchange Act Documents, or (ii) outstanding warrants, options or other securities disclosed in the Exchange Act Documents. The Shares to be sold pursuant to the Agreements have been duly authorized, and when issued and paid for in accordance with the terms of the Agreements will be duly and validly issued, fully paid and nonassessable. The outstanding shares of capital stock of the Company have been duly and validly issued and are fully paid and nonassessable, have been issued in compliance with all federal and state securities laws, and were not issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities. Except as set forth in or contemplated by the Exchange Act Documents, there are no outstanding rights (including, without limitation, preemptive rights), warrants or options to acquire, or instruments convertible into or exchangeable for, any unissued shares of capital stock or other equity interest in the Company or any Subsidiary, or any contract, commitment, agreement, understanding or arrangement of any kind to which the Company is a party and relating to the issuance or sale of any capital stock of the Company or any Subsidiary, any such convertible or exchangeable securities or any such rights, warrants or options. Without limiting the foregoing, no preemptive right, co-sale right, right of first refusal, registration right, or other similar right exists with respect to the Shares or the issuance and sale thereof,

-3-

except for certain “piggy-back” registration rights granted by the Company on or before June 20, 2000, which registration rights (including all rights to notice related thereto) have been waived by all of the holders thereof in connection with the filing of, and the proposal to file, the Registration Statement (defined below). No further approval or authorization of any stockholder, the Board of Directors of the Company or others is required for the issuance and sale of the Shares. The Company owns the entire equity interest in each of its Subsidiaries, free and clear of any pledge, lien, security interest, encumbrance, claim or equitable interest, other than as described in the Exchange Act Documents. Except as disclosed in the Exchange Act Documents, there are no stockholders agreements, voting agreements or other similar agreements with respect to the voting of the Common Stock to which the Company is a party or, to the knowledge of the Company, between or among any of the Company’s stockholders.

4.5 Legal Proceedings. There is no material legal or governmental proceeding pending or, to the knowledge of the Company, threatened to which the Company or any Subsidiary is or may be a party or of which the business or property of the Company or any Subsidiary is subject that is not disclosed in the Exchange Act Documents or in any of the Press Releases.

4.6 No Violations. Neither the Company nor any Subsidiary is in violation of its charter, bylaws, or other organizational document, or in violation of any law, administrative regulation, ordinance or order of any court or governmental agency, arbitration panel or authority applicable to the Company or any Subsidiary, which violation, individually or in the aggregate, would be reasonably likely to have a Material Adverse Effect, or is in default (and there exists no condition which, with the passage of time or otherwise, would constitute a default) in any material respect in the performance of Exchange Act Exhibit, which would be reasonably likely to have a Material Adverse Effect.

4.7 Governmental Permits, Etc. With the exception of the matters which are dealt with separately in Sections 4.1, 4.12, 4.13, and 4.14, each of the Company and its Subsidiaries has all necessary franchises, licenses, certificates and other authorizations from any foreign, federal, state or local government or governmental agency, department, or body that are currently necessary for the operation of the business of the Company and its Subsidiaries as currently conducted and as described in the Exchange Act Documents except where the failure to currently possess could not reasonably be expected to have a Material Adverse Effect.

4.8 Intellectual Property. Except as specifically disclosed in the Exchange Act Documents, (i) each of the Company and its Subsidiaries owns or possesses sufficient rights to use all material patents, patent rights, trademarks, copyrights, licenses, inventions, trade secrets, trade names and know-how (collectively, “Intellectual Property”) described or referred to in the Exchange Act Documents as owned or possessed by it or that are necessary for the conduct of its business as described in the Exchange Act Documents except where the failure to currently own or possess would not have a Material Adverse Effect, (ii) to the knowledge of the Company, neither the Company nor any of its Subsidiaries is infringing any rights of a third party with respect to any Intellectual Property that, individually or in the aggregate, would have a Material Adverse Effect, (iii) neither the Company nor any of its Subsidiaries has received any notice of, or has any knowledge of, any asserted infringement by the Company or any of its Subsidiaries of, any rights of a third party with respect to any Intellectual Property that, individually or in the aggregate, would have a Material Adverse Effect if determined adversely to the Company and (iv) neither the Company nor any of its Subsidiaries has received any notice of, or has any knowledge of, infringement by a third party with respect to any Intellectual Property rights of the Company or of any Subsidiary that, individually or in the aggregate, would have a Material Adverse Effect.

4.9 Financial Statements. The financial statements of the Company and the related notes contained in the Exchange Act Documents present fairly, in accordance with generally accepted accounting principles, the financial position of the Company and its Subsidiaries as of the dates indicated, and the results of its operations and cash flows for the periods therein specified consistent with the books and records of the Company and its Subsidiaries except that the unaudited interim financial statements were or are subject to normal and recurring year-end adjustments which are not expected to be material in amount. Such financial statements (including the related notes) have been prepared in accordance with generally accepted accounting principles applied on a consistent basis throughout the periods therein specified, except as may be disclosed in the notes to such financial statements, or in the case of unaudited statements, as may be permitted by the Securities and Exchange Commission (the “SEC”) on Form 10-Q under the Exchange Act and except as disclosed in the Exchange Act Documents.

-4-

damage (whether or not insured) to the physical property of the Company or any of its Subsidiaries which has been sustained which has a Material Adverse Effect; provided, however, that changes in the ordinary course of business, including but not limited to the use of cash and increases in liabilities in the ordinary course of business, shall not be deemed to be a material adverse change or to have a Material Adverse Effect.

4.11 Disclosure. The representations and warranties of the Company contained in this Section 4 as of the date hereof and as of the Closing Date, do not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Except with respect to the material terms and conditions of the transaction contemplated by the Agreements, which shall be publicly disclosed by the Company pursuant to Section 16 hereof, the Company confirms that neither it nor any person acting on its behalf has provided Investor with any information that the Company believes constitutes material, non-public information. The Company understands and confirms that Investor will rely on the foregoing representations in effecting transactions in securities of the Company.

4.12 NASDAQ Compliance. The Company’s Common Stock is registered pursuant to Section 12(g) of the Exchange Act and is listed on The Nasdaq Stock Market, Inc. National Market (the “Nasdaq National Market”), and the Company has taken no action designed to, or likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act or de-listing the Common Stock from the Nasdaq National Market, nor has the Company received any notification that the SEC or the National Association of Securities Dealers, Inc. (“NASD”) is contemplating terminating such registration or listing.

4.13 Reporting Status. The Company has filed in a timely manner all documents that the Company was required to file under the Exchange Act during the 12 months preceding the date of this Agreement.

-5-

Report on Form 10-K for the year ended December 31, 2002 into the Registration Statement and the prospectus which forms a part thereof, are independent accountants as required by the Securities Act and the rules and regulations promulgated thereunder.

4.19 Contracts. The contracts described in the Exchange Act Documents that are material to the Company are in full force and effect on the date hereof, and neither the Company nor, to the Company’s knowledge, any other party to such contracts is in breach of or default under any of such contracts which would have a Material Adverse Effect.

4.20 Taxes. The Company has filed all necessary federal, state and foreign income and franchise tax returns and has paid or accrued all taxes shown as due thereon, and the Company has no knowledge of a tax deficiency which has been or might be asserted or threatened against it which would have a Material Adverse Effect.

4.21 Transfer Taxes. On the Closing Date, all stock transfer or other taxes (other than income taxes) which are required to be paid in connection with the sale and transfer of the Shares to be sold to the Investor hereunder will be, or will have been, fully paid or provided for by the Company and all laws imposing such taxes will be or will have been fully complied with.

4.22 Private Offering. Assuming the correctness of the representations and warranties of the Investors set forth in Section 5 hereof, the offer and sale of Shares hereunder is exempt from registration under the Securities Act. The Company has not distributed and will not distribute prior to the Closing Date any offering material in connection with this Offering and sale of the Shares other than the documents of which this Agreement is a part, the Exchange Act Documents and the Press Releases. The Company has not in the past nor will it hereafter take any action independent of the placement agent to sell, offer for sale or solicit offers to buy any securities of the Company which would bring the offer, issuance or sale of the Shares as contemplated by this Agreement, within the provisions of Section 5 of the Securities Act, unless such offer, issuance or sale was or shall be within the exemptions of Section 4 of the Securities Act.

4.23 Disclosure Controls and Procedures; Internal Controls. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company, including its Subsidiaries, is made known to the certifying officers by others within those entities, particularly during the period in which the Form 10-K or Form 10-Q, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of a date within ninety (90) days prior to the filing date of the Form 10-Q for the quarter ended September 30, 2002 (such date, the “Evaluation Date”). The Company presented in the Form 10-Q for the quarter ended September 30, 2002 the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no significant changes in the Company’s internal controls (as such term is used in Item 307(b) of Regulation S-K under the Exchange Act) or, to the Company’s knowledge, in other factors that could significantly affect the Company’s internal controls.

4.24 Transactions With Affiliates. Except as disclosed in the Exchange Act Documents, none of the officers or directors of the Company is presently a party to any transaction with the Company or any Subsidiary (other than for services as employees, officers and directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring payments to or from any officer or director or, to the knowledge of the Company, any entity in which any officer or director has a substantial interest or is an officer, director, trustee or partner.

4.25 Solvency. Based on the financial condition of the Company as of the Closing Date, (i) the Company’s fair saleable value of its assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including known contingent liabilities) as they mature; (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business for the current fiscal year as now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the business conducted by the Company, and projected capital requirements and capital availability thereof; and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its debt when such amounts are required to be paid.

5. Representations, Warranties and Covenants of the Investor.

5.1 The Investor represents and warrants to, and covenants with, the Company that: (i) the Investor is an “accredited investor” as defined in Regulation D under the Securities Act and the Investor is also knowledgeable, sophisticated and experienced in making, and is qualified to make decisions with respect to investments in shares presenting an investment decision

like that involved in the purchase of the Shares, including investments in securities issued by the Company and investments in comparable companies, and has requested, received, reviewed and considered all information it deemed relevant in making an informed decision to purchase the Shares; (ii) the Investor is acquiring the number of Shares set forth in Section 3 of the Stock Purchase Agreement in the ordinary course of its business and for its own account for investment only and with no present intention of distributing any of such Shares or any arrangement or understanding with any other persons regarding the distribution of such Shares; (iii) the Investor will not, directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) any of the Shares except in compliance with the Securities Act, applicable state securities laws and the respective rules and regulations promulgated thereunder; (iv) the Investor has answered all questions on the Investor Questionnaire for use in preparation of the Registration Statement and the answers thereto are true, correct and complete as of the date hereof and will be true, correct and complete as of the Closing Date; (v) the Investor will notify the Company immediately of any change in any of such information until such time as the Investor has sold all of its Shares or until the Company is no longer required to keep the Registration Statement effective; and (vi) the Investor has, in connection with its decision to purchase the number of Shares set forth in Section 3 of the Stock Purchase Agreement, relied only upon the Exchange Act Documents, the Press Releases and the representations and warranties of the Company contained herein. The Investor understands that its acquisition of the Shares has not been registered under the Securities Act or registered or qualified under any state securities law in reliance on specific exemptions therefrom, which exemptions may depend upon, among other things, the bona fide nature of the Investor’s investment intent as expressed herein. Subject to compliance with the Securities Act, applicable securities laws and the respective rules and regulations promulgated thereunder, nothing contained herein shall be deemed a representation or warranty by such Investor to hold the Shares for any period of time.

5.2 The Investor acknowledges, represents and agrees that no action has been or will be taken in any jurisdiction outside the United States by the Company that would permit an offering of the Shares, or possession or distribution of offering materials in connection with the issue of the Shares, in any jurisdiction outside the United States where legal action by the Company for that purpose is required. Each Investor outside the United States will comply with all applicable laws and regulations in each foreign jurisdiction in which it purchases, offers, sells or delivers Shares or has in its possession or distributes any offering material, in all cases at its own expense.

5.3 The Investor hereby covenants with the Company not to make any sale of the Shares without complying with the provisions of this Agreement and without causing the prospectus delivery requirement under the Securities Act to be satisfied (whether by delivery of the Prospectus or pursuant to and in compliance with an exemption from such requirement), and the Investor acknowledges that the certificates evidencing the Shares will be imprinted with a legend that prohibits their transfer except in accordance therewith. The Investor acknowledges that there may occasionally be times when the Company determines that it must suspend the use of the Prospectus forming a part of the Registration Statement, as set forth in Section 7.2(c).

5.4 The Investor further represents and warrants to, and covenants with, the Company that (i) the Investor has full right, power, authority and capacity to enter into this Agreement and to consummate the transactions contemplated hereby and has taken all necessary action to authorize the execution, delivery and performance of this Agreement, and (ii) this Agreement constitutes a valid and binding obligation of the Investor enforceable against the Investor in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and except as enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and except as the indemnification agreements of the Investors herein may be legally unenforceable.

5.5 Investor will not use any of the Shares acquired pursuant to this Agreement to cover any short position in the Common Stock of the Company if doing so would be in violation of applicable securities laws.

5.6 The Investor understands that nothing in the Exchange Act Documents, the Press Releases, this Agreement or any other materials presented to the Investor in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice. The Investor has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of Shares.

5.7 The Company acknowledges and agrees that Investor does not make or has not made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in this Sections 5 and 16(a), in the Stock Purchase Agreement or in the Investor Questionnaire.

Notwithstanding any investigation made by any party to this Agreement, all covenants, agreements, representations and warranties made by the Company and the Investor herein shall survive the execution of this Agreement, the delivery to the Investor of the Shares being purchased and the payment therefor.

(a) subject to receipt of necessary information from the Investor after prompt request from the Company to the Investors to provide such information, prepare and file with the SEC, within 10 days after the Closing Date (or, if such tenth day is a Saturday, Sunday or holiday, then by the next succeeding business day), a registration statement on Form S-3 (the “Registration Statement”) to enable the resale of the Shares by the Investors from time to time through the automated quotation system of the Nasdaq National Market or in privately-negotiated transactions;

(b) subject to receipt of necessary information from the Investor after prompt request from the Company to the Investors to provide such information, use its best efforts to cause the Registration Statement to become effective within 45 days after the Registration Statement is filed by the Company, such efforts to include, without limiting the generality of the foregoing, preparing and filing with the SEC in such 45-day period any financial statements that are required to be filed prior to the effectiveness of such Registration Statement;

(c) use its best efforts to prepare and file with the SEC such amendments and supplements to the Registration Statement and the prospectus used in connection therewith (the “Prospectus”) as may be necessary to keep the Registration Statement current, effective and free from any material misstatement or omission to state a material fact for a period not exceeding, with respect to each Investor’s Shares purchased hereunder, the earlier of (i) the second anniversary of the Closing Date, (ii) the date on which the Investor may sell all Shares then held by the Investor without restriction by the volume limitations of Rule 144(e) of the Securities Act, or (iii) such time as all Shares purchased by such Investor in this Offering have been sold pursuant to a registration statement;

(d) furnish to the Investor with respect to the Shares registered under the Registration Statement such number of copies of the Registration Statement, Prospectuses and Preliminary Prospectuses in conformity with the requirements of the Securities Act and such other documents as the Investor may reasonably request in writing, in order to facilitate the public sale or other disposition of all or any of the Shares by the Investor; provided, however, that the obligation of the Company to deliver copies of Prospectuses or Preliminary Prospectuses to the Investor shall be subject to the receipt by the Company of reasonable assurances from the Investor that the Investor will comply with the applicable provisions of the Securities Act and of such other securities or blue sky laws as may be applicable in connection with any use of such Prospectuses or Preliminary Prospectuses;

(e) file documents required of the Company for normal blue sky clearance in states specified in writing by the Investor and use its best efforts to maintain such blue sky qualifications during the period the Company is required to maintain the effectiveness of the Registration Statement pursuant to Section 7.1(c); provided, however, that the Company shall not be required to qualify to do business or consent to service of process in any jurisdiction in which it is not now so qualified or has not so consented;

(f) bear all expenses in connection with the procedures in paragraph (a) through (e) of this Section 7.1 (other than any underwriting discounts or commissions, brokers’ fees and similar selling expenses, and any other fees or expenses incurred by the Investor, including attorneys’ fees) and the registration of the Shares pursuant to the Registration Statement; and

(g) advise the Investor, promptly after it shall receive notice or obtain knowledge of the issuance of any stop order by the SEC delaying or suspending the effectiveness of the Registration Statement or of the initiation or threat of any proceeding for that purpose; and it will promptly use its best efforts to prevent the issuance of any stop order or to obtain its withdrawal at the earliest possible moment if such stop order should be issued.

Notwithstanding anything to the contrary herein, the Registration Statement shall cover only the Shares. In no event at any time before the Registration Statement becomes effective with respect to the Shares shall the Company publicly announce or file any other registration statement, other than registrations on Form S-8 or for transactions covered by Rule 145 of the Securities Act, without the prior written consent of a majority in interest of the Investors. The Investor acknowledges and agrees that the Company shall not be regarded to have breached its “best efforts” obligation under Section 7.1(b) if, owing to a review of the Registration Statement by the SEC staff, the Registration Statement does not become effective within 45 days after the Registration Statement is filed with the SEC, provided that following receipt of notice of such review, the Company shall have used its best efforts to cause the Registration Statement to become effective at the earliest practicable date.

-8-

The Company understands that the Investor disclaims being an underwriter, but the Investor being deemed an underwriter by the SEC shall not relieve the Company of any obligations it has hereunder; provided, however, that if the Company receives notification from the SEC that the Investor is deemed an underwriter, then the period by which the Company is obligated to submit an acceleration request to the SEC shall be extended to the earlier of (i) the 90th day after such SEC notification, or (ii) 120 days after the initial filing of the Registration Statement with the SEC.

7.2 Transfer of Shares After Registration; Suspension.

(a) The Investor agrees that it will not effect any disposition of the Shares or its right to purchase the Shares that would constitute a sale within the meaning of the Securities Act except as contemplated in the Registration Statement referred to in Section 7.1 and as described below or as otherwise permitted by law, and that it will promptly notify the Company of any changes in the information set forth in the Registration Statement regarding the Investor or its plan of distribution.

(b) Except in the event that paragraph (c) below applies, the Company shall (i) if deemed necessary by the Company, prepare and file from time to time with the SEC a post-effective amendment to the Registration Statement or a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that such Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and so that, as thereafter delivered to purchasers of the Shares being sold thereunder, such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; (ii) provide the Investor copies of any documents filed pursuant to Section 7.2(b)(i) as the Investor may reasonably request; and (iii) inform each Investor that the Company has complied with its obligations in Section 7.2(b)(i) (or that, if the Company has filed a post-effective amendment to the Registration Statement which has not yet been declared effective, the Company will notify the Investor to that effect, will use its best efforts to secure the effectiveness of such post-effective amendment as promptly as possible and will promptly notify the Investor pursuant to Section 7.2(b)(i) hereof when the amendment has become effective).

(c) Subject to paragraph (d) below, in the event (i) of any request by the SEC or any other federal or state governmental authority during the period of effectiveness of the Registration Statement for amendments or supplements to a Registration Statement or related Prospectus or for additional information; (ii) of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration Statement or the initiation of any proceedings for that purpose; (iii) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; or (iv) of any event or circumstance which, upon the advice of its counsel, necessitates the making of any changes in the Registration Statement or Prospectus, or any document incorporated or deemed to be incorporated therein by reference, so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or any omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the Prospectus, it will not contain any untrue statement of a material fact or any omission to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; then the Company shall deliver a certificate in writing to the Investor (the “Suspension Notice”) to the effect of the foregoing and, upon receipt of such Suspension Notice, the Investor will refrain from selling any Shares pursuant to the Registration Statement (a “Suspension”) until the Investor’s receipt of copies of a supplemented or amended Prospectus prepared and filed by the Company, or until it is advised in writing by the Company that the current Prospectus may be used, and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in any such Prospectus. In the event of any Suspension, the Company will use its best efforts to cause the use of the Prospectus so suspended to be resumed as soon as reasonably practicable within 20 business days after the delivery of a Suspension Notice to the Investor.

(d) Notwithstanding the foregoing paragraphs of this Section 7.2, the Investor shall not be prohibited from selling Shares under the Registration Statement as a result of Suspensions on more than two occasions of not more than 30 days each in any twelve month period, unless, in the good faith judgment of the Company’s Board of Directors, upon the written opinion of counsel of counsel, the sale of Shares under the Registration Statement in reliance on this paragraph 7.2(d) would be reasonably likely to cause a violation of the Securities Act or the Exchange Act and result in liability to the Company.

(e) Provided that a Suspension is not then in effect, the Investor may sell Shares under the Registration Statement, provided that it arranges for delivery of a current Prospectus to the transferee of such Shares. The Company shall provide such number of current Prospectuses to the Investor as the Investor may reasonably request, and shall supply copies to any other parties reasonably requiring such Prospectuses.

-9-

(f) In the event of a sale of Shares by the Investor pursuant to the Registration Statement, the Investor must also deliver to the Company’s transfer agent, with a copy to the Company, a Certificate of Subsequent Sale substantially in the form attached hereto as Exhibit A, so that the Shares may be properly transferred.

7.3 Indemnification. For the purpose of this Section 7.3:

(i) the term “Selling Stockholder” means the Investor and any affiliate of such Investor; and

(ii) the term “Registration Statement” shall include the Prospectus in the form first filed with the SEC pursuant to Rule 424(b) of the Securities Act or filed as part of the Registration Statement at the time of effectiveness if no Rule 424(b) filing is required, and any exhibit, supplement or amendment included in or relating to the Registration Statement referred to in Section 7.1; and

(iii) the term “Untrue Statement” means any untrue statement or alleged untrue statement, or any omission or alleged omission to state in the Registration Statement, as amended or supplemented from time to time, a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(a) The Company agrees to indemnify and hold harmless each Selling Stockholder from and against any losses, claims, damages or liabilities to which such Selling Stockholder may become subject (under the Securities Act or otherwise) insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon (i) any breach of the representations or warranties of the Company contained herein or failure to comply with the covenants and agreements of the Company contained herein, (ii) any Untrue Statement, or (iii) any failure by the Company to fulfill any undertaking included in the Registration Statement, as amended or supplemented from time to time, and the Company will reimburse such Selling Stockholder for any reasonable legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim, or preparing to defend any such action, proceeding or claim, provided, however, that the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of, or is based upon, an Untrue Statement made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Selling Stockholder specifically for use in preparation of the Registration Statement, as amended or supplemented from time to time (including, without limitation, information set forth in the Investor Questionnaire), or the failure of such Selling Stockholder to comply with its covenants and agreements contained in Section 7.2 hereof respecting sale of the Shares or any statement or omission in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Selling Stockholder prior to the pertinent sale or sales by the Selling Stockholder. The Company shall reimburse each Selling Stockholder for the indemnifiable amounts provided for herein on demand as such expenses are incurred.

(b) The Investor agrees to indemnify and hold harmless the Company (and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, each officer of the Company who signs the Registration Statement and each director of the Company) from and against any losses, claims, damages or liabilities to which the Company (or any such officer, director or controlling person) may become subject (under the Securities Act or otherwise), insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, (i) any failure to comply with the covenants and agreements contained in Section 7.2 hereof respecting sale of the Shares, or (ii) any Untrue Statement if such Untrue Statement was made in reliance upon and in conformity with written information furnished by or on behalf of the Investor specifically for use in preparation of the Registration Statement, as amended or supplemented from time to time (including, without limitation, information set forth in the Investor Questionnaire), and the Investor will reimburse the Company or such officer, director or controlling person, as the case may be, for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim. The Investor shall reimburse the Company or such officer, director or controlling person, as the case may be, for the indemnifiable amounts provided for herein on demand as such expenses are incurred. Notwithstanding the foregoing, the Investor’s aggregate obligation to indemnify the Company and such officers, directors and controlling persons shall be limited to the net amount received by the Investor from the sale of the Shares.

(c) Promptly after receipt by any indemnified person of a notice of a claim or the beginning of any action in respect of which indemnity is to be sought against an indemnifying person pursuant to this Section 7.3, such indemnified person shall notify the indemnifying person in writing of such claim or of the commencement of such action, but the omission to so notify the indemnifying person will not relieve it from any liability which it may have to any indemnified person under this Section 7.3 (except to the extent that such omission materially and adversely affects the indemnifying person’s ability to defend such action) or from any liability otherwise than under this Section 7.3. Subject to the provisions hereinafter stated, in case any

-10-

such action shall be brought against an indemnified person, the indemnifying person shall be entitled to participate therein, and, to the extent that it shall elect by written notice delivered to the indemnified person promptly after receiving the aforesaid notice from such indemnified person, shall be entitled to assume the defense thereof, with counsel reasonably satisfactory to such indemnified person. After notice from the indemnifying person to such indemnified person of its election to assume the defense thereof, such indemnifying person shall not be liable to such indemnified person for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof, provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate, in the opinion of counsel to the indemnified person, for the same counsel to represent both the indemnified person and such indemnifying person or any affiliate or associate thereof, the indemnified person shall be entitled to retain its own counsel at the expense of such indemnifying person; provided, however, that no indemnifying person shall be responsible for the fees and expenses of more than one separate counsel (together with appropriate local counsel) for all indemnified parties. In no event shall any indemnifying person be liable in respect of any amounts paid in settlement of any action unless the indemnifying person shall have approved the terms of such settlement; provided that such consent shall not be unreasonably withheld or delayed. No indemnifying person shall, without the prior written consent of the indemnified person, effect any settlement of any pending or threatened proceeding in respect of which any indemnified person is or could have been a party and indemnification could have been sought hereunder by such indemnified person, unless such settlement includes an unconditional release of such indemnified person from all liability on claims that are the subject matter of such proceeding.

(d) If the indemnification provided for in this Section 7.3 is unavailable to or insufficient to hold harmless an indemnified person under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying person shall contribute to the amount paid or payable by such indemnified person as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Investor, as well as any other Selling Shareholders under such Registration Statement on the other in connection with the statements or omissions or other matters which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, in the case of an Untrue Statement, whether the Untrue Statement relates to information supplied by the Company on the one hand or an Investor or other Selling Shareholder on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such Untrue Statement. The Company and the Investor agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Investor and other Selling Shareholders were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified person as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), the Investor shall not be required to contribute any amount in excess of the amount by which the net amount received by the Investor from the sale of the Shares to which such loss relates exceeds the amount of any damages which such Investor has otherwise been required to pay by reason of such Untrue Statement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Investor’s obligations in this subsection to contribute shall be in proportion to its Investor sale of Shares to which such loss relates and shall not be joint with any other Selling Shareholders.

(e) The parties to this Agreement hereby acknowledge that they are sophisticated business persons who were represented by counsel during the negotiations regarding the provisions hereof including, without limitation, the provisions of this Section 7.3, and are fully informed regarding said provisions. They further acknowledge that the provisions of this Section 7.3 fairly allocate the risks in light of the ability of the parties to investigate the Company and its business in order to assure that adequate disclosure is made in the Registration Statement as required by the Securities Act and the Exchange Act. The parties are advised that federal or state public policy as interpreted by the courts in certain jurisdictions may be contrary to certain of the provisions of this Section 7.3, and the parties hereto hereby expressly waive and relinquish any right or ability to assert such public policy as a defense to a claim under this Section 7.3 and further agree not to attempt to assert any such defense.

7.4 Termination of Conditions and Obligations. The conditions precedent imposed by Section 5 or this Section 7 upon the transferability of the Shares shall cease and terminate as to any particular number of the Shares when such Shares shall have been effectively registered under the Securities Act and sold or otherwise disposed of in accordance with the intended method of disposition set forth in the Registration Statement covering such Shares or at such time as an opinion of counsel reasonably satisfactory to the Company shall have been rendered to the effect that such conditions are not necessary in order to comply with the Securities Act.

-11-

7.5 Information Available. So long as the Registration Statement is effective covering the resale of Shares owned by the Investor, the Company will furnish to the Investor:

(a) as soon as practicable after it is available, one copy of (i) its Annual Report to Stockholders (which Annual Report shall contain financial statements audited in accordance with generally accepted accounting principles by a national firm of certified public accountants), (ii) its Annual Report on Form 10-K and (iii) its Quarterly Reports on Form 10-Q (the foregoing, in each case, excluding exhibits);

(b) upon the request of the Investor, all exhibits excluded by the parenthetical to subparagraph (a) of this Section 7.5 as filed with the SEC and all other information that is made available to shareholders; and

(c) upon the reasonable request of the Investor, an adequate number of copies of the Prospectuses to supply to any other party requiring such Prospectuses; and upon the reasonable request of the Investor, the President or the Chief Financial Officer of the Company (or an appropriate designee thereof) will meet with the Investor or a representative thereof at the Company’s headquarters to discuss all information relevant for disclosure in the Registration Statement covering the Shares and will otherwise cooperate with any Investor conducting an investigation for the purpose of reducing or eliminating such Investor’s exposure to liability under the Securities Act, including the reasonable production of information at the Company’s headquarters; provided that the Company shall not be required to disclose any confidential information to or meet at its headquarters with any Investor until and unless the Investor shall have entered into a confidentiality agreement in form and substance reasonably satisfactory to the Company with the Company with respect thereto.

7.6 Legend; Restrictions on Transfer. The certificate or certificates for the Shares (and any securities issued in respect of or exchange for the Shares) shall be subject to a legend or legends restricting transfer under the Securities Act and referring to restrictions on transfer herein, such legend to be substantially as follows:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL, IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

The Company and the Investor acknowledge and agree that the Investor may, as permitted by law, from time to time pledge pursuant to a bona fide margin agreement or grant a security interest in some or all of the Shares and, if required under the terms of such arrangement, Investor may, as permitted by law, transfer pledged or secured Shares to the pledgees or secured parties. So long as Investor is not an affiliate of the Company, such a pledge or transfer would not be subject to approval or consent of the Company and would not require the legal opinion of legal counsel to the pledgee, secured party or pledgor. At the Investor’s expense, so long as the Shares are subject to the legend required by this Section 7.6, the Company will use its best efforts to execute and deliver such reasonable documentation as a pledgee or secured party of Shares may reasonably request in connection with a pledge or transfer of the Shares including such amendments or supplements to the Registration Statement and Prospectus as may be reasonably required. The foregoing does not affect Investor’s obligations pursuant to Section 7.2(a).

7.7 Liquidated Damages. The Company and Investor agree that Investor will suffer damages if the Company fails to fulfill its obligations pursuant to Section 7.1 and 7.2 hereof and that it would not be possible to ascertain the extent of such damages with precision. Accordingly, the Company hereby agrees to pay liquidated damages (“Liquidated Damages”) to Investor under the following circumstances: (a) if the Registration Statement is not filed by the Company on or prior to 30 days after the Closing Date (such an event, a “Filing Default”); (b) if the Registration Statement is not declared effective by the SEC on or prior to 90 days after the Closing Date (such an event, an “Effectiveness Default”); or (c) if the Registration Statement (after its effectiveness date) ceases to be effective and available to Investor for any continuous period that exceeds 30 days or for one or more period that exceeds in the aggregate 60 days in any 12-month period (such an event, a “Suspension Default” and together with a Filing Default and an Effectiveness Default, a “Registration Default”). In the event of a Registration Default, the Company shall as Liquidated Damages pay to Investor, for each 30-day period of a Registration Default, an amount in cash equal to 1% of the aggregate purchase price paid by Investor pursuant to this Agreement; provided that in no event shall the aggregate amount of cash to be paid as Liquidated Damages pursuant to this Section 7.7 exceed 9% of the aggregate purchase price paid by Investor. The Company shall pay the Liquidated Damages as follows: (i) in connection with a Filing Default, on the 31st day after the Closing Date, and each 30th day thereafter until the Registration Statement is filed with the SEC; (ii) in connection with an Effectiveness Default, on the 91st day after the Closing Date, and each 30th day thereafter until the Registration Statement is declared effective by the SEC; or (iii) in connection with a Suspension Default, on either (x) the 31st consecutive day of any Suspension or (y) the 61st

-12-

day (in the aggregate) of any Suspensions in any 12-month period, and each 30^th day thereafter until the Suspension is terminated in accordance with Section 7.2. Notwithstanding the foregoing, all periods shall be tolled during delays directly caused by the action or inaction of any Investor, and the Company shall have no liability to any Investor in respect of any such delay. The Liquidated Damages payable herein shall apply on a pro rata basis for any portion of a 30-day period of a Registration Default.

8. Notices. All notices, requests, consents and other communications hereunder shall be in writing, shall be mailed (A) if within the United States by first-class registered or certified airmail, or nationally recognized overnight express courier, postage prepaid, or by facsimile, or (B) if delivered from outside the United States, by International Federal Express (or other recognized international express courier)or facsimile, and shall be deemed given (i) if delivered by first-class registered or certified mail, three business days after so mailed, (ii) if delivered by nationally recognized overnight carrier, one business day after so mailed, (iii) if delivered by International Federal Express (or other recognized international express courier), two business days after so mailed, (iv) if delivered by facsimile, upon electronic confirmation of receipt and shall be delivered as addressed as follows:

C. REPRESENTATIONS

The undersigned hereby represents and warrants to the Corporation as follows:

Any purchase of the Securities would be solely for the account of the undersigned and not for the account of any other person or with a view to any resale, fractionalization, division, or distribution thereof.

¹ As used in this Questionnaire, the term “net worth” means the excess of total assets over total liabilities. In computing net worth for the purpose of subsection (4), the principal residence of the investor must be valued at cost, including cost of improvements, or at recently appraised value by an institutional lender making a secured loan, net of encumbrances. In determining income, the investor should add to the investor’s adjusted gross income any amounts attributable to tax exempt income received, losses claimed as a limited partner in any limited partnership, deductions claimed for depiction, contributions to an XXX or XXXXX retirement plan, alimony payments, and any amount by which income from long-term capital gains has been reduced in arriving at adjusted gross income.

The information contained herein is complete and accurate and may be relied upon by the Corporation, and the undersigned will notify the Corporation immediately of any material change in any of such information occurring prior to the closing, if any, with respect to the purchase of Securities by the undersigned or any co-purchaser.

There are no suits, pending litigation, or claims against the undersigned that could materially affect the net worth of the undersigned as reported in this Questionnaire.

The undersigned acknowledges that there may occasionally be times when the Corporation determines that it must suspend the use of the Prospectus forming a part of the Registration Statement (as such terms are defined in the Stock Purchase Agreement to which this Questionnaire is attached), as set forth in Section 7.2(c) of the Stock Purchase Agreement. The undersigned is aware that, in such event, the Securities will not be subject to ready liquidation, and that any Securities purchased by the undersigned would have to be held during such suspension. The overall commitment of the undersigned to investments which are not readily marketable is not excessive in view of the undersigned’s net worth and financial circumstances, and any purchase of the Securities will not cause such commitment to become excessive. The undersigned is able to bear the economic risk of an investment in the Securities.

The undersigned has carefully considered the potential risks relating to the Corporation and a purchase of the Securities, and fully understands that the Securities are speculative investments which involve a high degree of risk of loss of the undersigned’s entire investment. Among others, the undersigned has carefully considered each of the risks identified in the Exchange Act Documents.

IN WITNESS WHEREOF, the undersigned has executed this Questionnaire this day of January, 2003, and declares under oath that it is truthful and correct.

XXXX Medical Systems, Inc.; Registration Statement on Form S-3

Dear Selling Shareholder:

Enclosed please find five (5) copies of a prospectus dated , (the “Prospectus”) for your use in reselling your shares of common stock, $0.001 par value (the “Shares”), of XXXX Medical Systems, Inc. (the “Company”), under the Company’s Registration Statement on Form S-3 (Registration No. 333-______) (the “Registration Statement”), which has been declared effective by the Securities and Exchange Commission. As a selling shareholder under the Registration Statement, you have an obligation to deliver a copy of the Prospectus to each purchaser of your Shares, either directly or through the broker-dealer who executes the sale of your Shares.

The Company is obligated to notify you in the event that it suspends trading under the Registration Statement in accordance with the terms of the Stock Purchase Agreement between the Company and you. During the period that the Registration Statement remains effective and trading thereunder has not been suspended, you will be permitted to sell your Shares which are included in the Prospectus under the Registration Statement. Upon a sale of any Shares under the Registration Statement, you or your broker will be required to deliver to the Transfer Agent, U.S. Stock Transfer Corporation (1) your restricted stock certificate(s) representing the Shares, (2) instructions for transfer of the Shares sold, and (3) a representation letter from your broker, or from you if you are selling in a privately negotiated transaction, or from such other appropriate party, in the form of Exhibit A attached hereto (the “Representation Letter”). The Representation Letter confirms that the Shares have been sold pursuant to the Registration Statement and in a manner described under the caption “Plan of Distribution” in the Prospectus and that such sale was made in accordance with all applicable securities laws, including the prospectus delivery requirements.

Please note that you are under no obligation to sell your Shares during the registration period. However, if you do decide to sell, you must comply with the requirements described in this letter or otherwise applicable to such sale. Your failure to do so may result in liability under the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended. Please remember that all sales of your Shares must be carried out in the manner set forth under the caption “Plan of Distribution” in the Prospectus if you sell under the Registration Statement. The Company may require an opinion of counsel reasonably satisfactory to the Company if you choose another method of sale. You should consult with your own legal advisor(s) on an ongoing basis to ensure your compliance with the relevant securities laws and regulations.

In order to maintain the accuracy of the Prospectus, you must notify the undersigned upon the sale, gift, or other transfer of any Shares by you, including the number of Shares being transferred, and in the event of any other change in the information regarding you which is contained in the Prospectus. For example, you must notify the undersigned if you enter into any arrangement with a broker-dealer for the sale of shares through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker-dealer. Depending on the circumstances, such transactions may require the filing of a supplement to the Prospectus in order to update the information set forth under the caption “Plan of Distribution” in the Prospectus.

Should you need any additional copies of the Prospectus, or if you have any questions concerning the foregoing, please write to me at XXXX Medical Systems, Inc., 000 X. Xxxxxxxxx Xxxx., Xxxxxxxx Xxxx, XX 00000. Thank you.

Sincerely,
