(the "Company") and the investor whose name is set forth at the foot of this Agreement (the "Investor"). The parties hereto agree as follows: ARTICLE I Purchase and Sale of Preferred Stock ------------------------------------ Section 1.1 Purchase and Sale of Preferred Stock. Upon the following ------------------------------------ terms and conditions, the Company shall issue and sell to the Investor shares of the Company's First Convertible Preferred Stock (the "Shares") having the rights, designations and preferences set forth in Schedule I hereto, and the Investor shall purchase from the Company the number of Shares designated on the signature page hereof. Section 1.2 Purchase Price. The purchase price for the Shares (the -------------- "Purchase Price") shall be $25 per share. Section 1.3 The Closing. ----------- (a) The closing of the purchase and sale of the Shares (the "Closing"), shall take place at the offices of the Company, at 10:00 a.m., local time on the later of the following: (i) the date on which the last to be fulfilled or waived of the conditions set forth in Article IV hereof and applicable to the Closing shall be fulfilled or waived in accordance herewith, or (ii) such other time and place and/or on such other date as the Investor and the Company may agree. The date on which the Closing occurs is referred to herein as the "Closing Date." (b) On the Closing Date, the Company shall deliver to the Investor certificates representing the number of Shares being purchased by the Investor, registered in the name of the Investor, or deposit such Shares into accounts designated by the Investor, and the Investor shall deliver to the Company the Purchase Price for such Shares by cashier's check or wire transfer in immediately available funds to such account as shall be designated in writing by the Company. In addition, each party shall deliver all documents, instruments and writings required to be delivered by such party pursuant to this Agreement at or prior to the Closing. Section 1.4 Covenant to Register. -------------------- (a) For purposes of this Section, the following definitions shall apply: (i) The terms "register," "registered," and "registration" refer to a registration under the Securities Act of 1933, as amended (the "Act"), effected by preparing and filing a registration statement in compliance with the Act, and the declaration or ordering of effectiveness of such registration statement, document or amendment thereto. (ii) The term "Registrable Securities" means the stock issued or issuable upon conversion of the Shares, or otherwise issued or issuable pursuant to this Agreement or the provisions of Schedule I hereto, and any securities of the Company or securities of any successor corporation issued as, or issuable upon the conversion or exercise of any warrant, right or other security that is issued as a dividend or other distribution with respect to, or in exchange for or in replacement of the Shares, which (i) have not been resold pursuant to an effective registration statement or pursuant to Rule 144 under the Act and (ii) may not be resold pursuant to Rule 144(k) under the Act. For purposes of this Agreement, securities will be considered ineligible for resale pursuant to Rule 144(k) under the Act unless the Company's transfer agent has accepted an instruction from the Company specifying that such securities are eligible for sale pursuant to Rule 144(k). (iii) The term "holder of Registrable Securities" includes any person who holds Shares which are convertible into Registrable Securities. (b) (i) The Company shall, as expeditiously as possible following the Closing, file a registration statement on Form S-3, or if Form S-3 is not then available, another appropriate form, covering all the Registrable Securities and sales thereof under Rule 415, and shall use its best efforts to cause such registration statement to become effective by the 90th calendar day after the Closing Date (the "Initial Registration"). In the event such registration is not so declared effective or does not include all Registrable Securities, a holder of Registrable Securities shall have the right to require by notice in writing that the Company register all or any part of the Registrable Securities held by such holder (a "Demand Registration") and the Company shall thereupon effect such registration in accordance herewith (which may include adding such shares to an existing shelf registration). The parties agree that if the holder of Registrable Securities demands registration of less than all of the Registrable Securities, the Company, at its option, may nevertheless file a registration statement covering all of the Registrable Securities. If such registration statement is declared effective with respect to all Registrable Securities, then so long as the Company is in compliance with its obligations under Subsection (d)(i) through (v) hereof, the demand registration rights granted pursuant to this Subsection (b) (i) shall not be applicable. If such registration statement is not 2 declared effective with respect to all Registrable Securities, or if the Company is not in compliance with said obligations, the demand registration rights described herein shall remain in effect. The Company shall provide holders of Registrable Securities reasonable opportunity to review any such registration statement or amendment or supplement thereto prior to the filing thereof. If the Registrable Securities are registered initially on a form other than Form S- 3, the Company shall register the Registrable Securities on Form S-3 as soon as use of such form is permissible. (ii) The Company shall not be obligated to effect Demand Registration under Subsection (b)(i) if all of the Registrable Securities held by the holder of Registrable Securities which are demanded to be covered by the Demand Registration are, at the time of such demand, included in an effective registration statement and the Company is in compliance with its obligations under Subsection (d) (i) through (v) hereof. (iii) The Company may suspend the effectiveness of any such registration effected pursuant to this Subsection (b) in the event, and for such period of time as, such a suspension is required by the rules and regulations of the Securities and Exchange Commission ("SEC"), and may suspend use of the prospectus included in the Registration Statement if such prospectus ceases to meet the requirements of Section 10 of the Act. The Company will immediately advise the holders of the registered securities of any such suspension, and will use its best efforts to cause such suspension to terminate at the earliest possible date. (iv) If the registration statement covering all Registrable Securities is not effective by the 90th calendar day after the Closing Date, then the Company shall pay the Investor in cash an amount equal to 3% of the total Purchase Price of the Shares purchased by the Investor for each 30 day period thereafter until such registration statement is effective (pro- rata as to a period of less than 30 days); provided, however, that such payment, with respect to the first 60 days (but not thereafter), may be made in Shares valued at the Purchase Price. An amount equal to 3% of the total Purchase Price of Shares and any Registrable Securities then held by Investor shall also be paid to the Investor in cash during any period in excess of 30 days that (i) the effectiveness of the Registration Statement or use of the prospectus is suspended as set forth in Section 1.4 (b)(iii) or the prospectus is otherwise unavailable for use by sellers of Registrable Securities, or if the Registrable Securities are not listed and traded on NASDAQ or on a national securities exchange. Any payment hereunder shall be made not later than five business days after the end of the 30-day period with respect to which such payment is due and if not so paid the Shares shall be redeemable at the option of the holder thereof at their liquidation preference divided by 100% less the Applicable Percentage set forth in Schedule I hereto. The "Purchase Price" of Registrable Securities shall be (i) in the case of Registrable Securities derived from conversion or substitution of Shares, the Purchase Price of such Shares, and (ii) in the case of Registrable Securities 3 derived from dividend payments, the original dollar amount of such dividends. This subsection is in addition to the provisions of Section 7.2(a) hereof. (c) If the Company proposes to register (including for this purpose a registration effected by the Company for shareholders other than the Investor) any of its stock or other securities under the Act in connection with a public offering of such securities (other than a registration on Form S- 4, Form S-8 or other limited purpose form) and all Registrable Securities have not theretofore been included in a registration statement under Subsection (b) which remains effective, the Company shall, at such time, promptly give all holders of Registrable Securities written notice of such registration. Upon the written request of any holder of Registrable Securities given within twenty (20) days after receipt of such notice by the holder of Registrable Securities, the Company shall use its list efforts to cause to be registered under the Act all Registrable Securities that such holder of Registrable Securities requests to be registered. However, the Company shall have no obligation under this Subsection (c) to the extent that, with respect to a public offering registration, the managing underwriter of such public offering reasonably notifies such holder(s) in writing of its determination that the Registrable Securities or a portion thereof should be excluded therefrom. (d) Whenever required under this Section to effect the registration of any Registrable Securities, including, without limitation, the Initial Registration, the Company shall, as expeditiously as reasonably possible: (i) Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration to become effective as provided in Section 1.4(b)(i), and keep such registration statement effective for so long as any holder of Registrable Securities desires to dispose of the securities covered by such registration statement, or, if earlier, until such Registrable Securities may be sold under Rule 144(k) (provided that the Company's transfer agent has accepted an instruction from the Company to such effect). (ii) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Act with respect to the disposition of all securities covered by such registration statement and notify the holders of the filing and effectiveness of such Registration Statement and any amendments or supplements. (iii) Furnish to each holder of Registrable Securities such numbers of copies of a current prospectus conforming with the requirements of the Act, copies of the registration statement, any amendment or supplement thereto and any documents incorporated by reference therein and such other documents as such holder of 4 Registrable Securities may reasonably require in order to facilitate the disposition of Registrable Securities owned by such holder of Registrable Securities. (iv) Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or "Blue Sky" laws of such jurisdictions as shall be reasonably requested by a holder of Registrable Securities and keep such registration or qualification effective as long as required to permit sale of Registrable Securities thereunder, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions. (v) Notify each holder of Registrable Securities immediately of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and use its best efforts to promptly update and/or correct such prospectus. (vi) Furnish, at the request of any holder of Registrable Securities, (1) an opinion of counsel of the Company, dated the effective date of the registration statement, in form and substance reasonably satisfactory to the holder and its counsel and covering, without limitation, such matters as the due authorization and issuance of the securities being registered and compliance with securities laws by the Company in connection with the authorization, issuance and registration thereof and (2) a letter or letters of the Company's independent public accountants in form and substance reasonably satisfactory to the holder and its counsel. (vii) Use its best efforts to list the Registrable Securities covered by such registration statement with any national market or securities exchange on which the Common Stock is then listed, and make generally ------ available on a timely basis such statements of earnings as are required to comply with Section lla of the Act. (viii) Make available for inspection by the holder of Registrable Securities, upon request, all SEC Documents (as defined below) filed subsequent to the Closing and require the Company's officers, directors and employees to supply all information reasonably requested by any holder of Registrable Securities in connection with such registration statement. (e) Each holder of Registrable Securities will furnish to the Company in connection with any registration under this Section such information regarding itself, the Registrable Securities and other securities of the Company held by it, and the intended method of disposition of such securities as shall be reasonably required to effect the registration of the Registrable Securities held by such holder of 5 Registrable Securities. The Investor shall provide such data as of closing. The intended method of disposition (Plan of Distribution) of such securities as so provided by Investor shall be included without alteration in the Registration Statement covering the Registrable Securities and shall not be changed without written consent of the Investor. (f) (i) The Company shall indemnify, defend and hold harmless each holder of Registrable Securities which are included in a registration statement pursuant to the provisions of Subsections (b) or (c) (each, a "Selling Shareholder") and each of its officers, directors, employees, agents, partners or controlling persons (within the meaning of the Act) (each, an "indemnified party") from and against, and shall reimburse such indemnified party with respect to, any and all claims, suits, demands, causes of action, losses, damages, liabilities, costs or expenses ("Liabilities") to which such indemnified party may become subject under the Act or otherwise, arising from or relating to (A) any untrue statement or alleged untrue statement of any material fact contained in such registration statement, any prospectus contained therein or any amendment or supplement thereto, or (B) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the Company shall not be liable in -------- any such case to the extent that any such Liability arises out of or is based upon an untrue statement or omission so made in strict conformity with information furnished by such indemnified party in writing specifically for use in the registration statement; provided further, that the Company shall not be -------- ------- liable in any such case to the extent that any such Liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary prospectus if (i) a Selling Shareholder under an obligation to send or deliver a copy of the prospectus with or prior to the delivery of written confirmation of the sale of Registrable Securities to the person asserting such Liability who purchased such Registrable Securities which are the subject thereof from such Selling Shareholder failed to do so and (ii) the prospectus would have completely corrected such untrue statement or omission; and provided further, that the Company shall not be liable in any such -------- ------- case to the extent that any Liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission in the prospectus, if such untrue statement or alleged untrue statement, omission or alleged omission is completely corrected in an amendment or supplement to the prospectus and if, having previously been furnished by or on behalf of the Company with copies of the prospectuses so amended or supplemented and having been obligated to deliver such prospectuses, the Selling Shareholder thereafter failed to deliver such prospectus as so amended or supplemented, prior to or concurrently with the sale of Registrable Securities to the person asserting such Liability who purchased such Registrable Securities which are the subject thereof from such Selling Shareholder. (ii) In the event of any registration under the Act of Registrable Securities pursuant to Subsections (b) or (c), each holder of such Registrable 6 Securities hereby severally agrees to indemnify, defend and hold harmless the Company, and its officers, directors, employees, agents, partners, or controlling persons (within the meaning of the Act) (each, an "indemnified party") from and against, and shall reimburse such indemnified party with respect to, any and all Liabilities to which such indemnified party may become subject under the Act or otherwise, arising from or relating to (A) any untrue statement or alleged untrue statement of any material fact contained in such registration statement, any prospectus contained therein or any amendment or supplement thereto, or (B) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, that such holders will be liable in any such case to the extent, and - -------- only to the extent, that any such Liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, prospectus or amendment or supplement thereto in reliance upon and in strict conformity with written information furnished in an instrument duly executed by such holder specifically for use in the registration statement. (iii) Promptly after receipt by any indemnified party of notice of the commencement of any action, or after actual knowledge of any claim, such indemnified party shall, if a claim in respect thereof is to be made against another party (the "indemnifying party") hereunder, notify such party in writing thereof, but the omission so to notify shall not relieve the indemnifying party from any Liability which it may have to the indemnified party other than under this section and shall only relieve it from any liability which it may have to the indemnified party under this section if and to the extent it is actually prejudiced by such omission. In case any such action shall be brought against any indemnified party and such indemnified party shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party to the indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to the indemnified party under this section for any legal expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected, provided, -------- however, that if the defendants in any such action include both the indemnifying party and such indemnified party and the indemnified party shall have reasonably concluded that there may be reasonable defenses available to it which are different from or additional to those available to the indemnifying party or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, the indemnified party shall have the right to select a separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. In clarification of the foregoing, 7 if the Company is the indemnifying party it shall pay the reasonable expenses and fees of one separate counsel whose selection is approved by the largest group of similarly situated indemnified parties as measured by the aggregate par value of such Registrable Securities owned by such group. Any indemnified party who chooses not to be represented by the foregoing separate counsel shall be entitled, at its own expense to be represented by counsel of its own selection. An indemnifying party shall not be bound by or have liability in respect of any settlement entered into without its consent. (g) (i) With respect to the inclusion of Registrable Securities in a registration statement pursuant to Subsections (b) or (c), all fees, costs and expenses of and incidental to such registration, inclusion and public offering shall be borne by the Company; provided, however, that any Selling Shareholders participating in such registration shall bear their pro- rata share of the underwriting discounts and commissions, if any, incurred by them in connection with such registration. (ii) The fees, costs and expenses of registration to be borne by the Company as provided in this Subsection (g) shall include, without limitation, all registration, filing and NASD fees, printing expenses, fees and disbursements of counsel and accountants for the Company, and all legal fees and disbursements and other expenses of complying with state securities or Blue Sky laws of any jurisdiction or jurisdictions in which securities to be offered are to be registered and qualified. Subject to appropriate agreements as to confidentiality, the Company shall make available to counsel for the holders of Registrable Securities its documents and personnel for due diligence purposes, and shall pay the reasonable fees and disbursements of one law firm (but not more than one) acting as counsel for a majority of such holders. Except as otherwise provided herein, fees and disbursements of counsel and accountants for the Selling Shareholders shall be borne by the respective Selling Shareholders. (h) The rights to cause the Company to register all or any portion of Registrable Securities pursuant to this Section may be assigned by Investor to a transferee or assignee of 20% or more, in the aggregate, of its Shares or the Registrable Securities derived from such Shares. Any transferee asserting registration rights hereunder shall be bound by the applicable provisions of this Agreement. (i) From and after the date of this Agreement, the Company shall not agree to allow the holders of any securities of the Company to include any of their securities in any registration statement filed by the Company pursuant to Subsection (b) unless such inclusion will not reduce the amount of the Registrable Securities included therein. 8 ARTICLE II Representations and Warranties ------------------------------ Section 2.1 Representations and Warranties of the Company.
