(b) If the Holders initiating the registration request hereunder ("Initiating Holders") intend to distribute the Registrable Securities covered by 3 their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to subsection 1.2(a) and the Company shall include such information in the written notice referred to in subsection 1.2(a). The underwriter will be selected by the majority in interest of the Initiating Holders and shall be of nationally recognized standing and reasonably acceptable to the Company. In such event, the right of any Holder to include his Registrable Securities in such registration shall be conditioned upon such Holder's participation in such underwriting and the inclusion of such Holder's Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder) to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in subsection 1.4(e)) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of this Section 1.2, if the underwriter advises the Initiating Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Initiating Holders shall so advise all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated among all Holders electing to include shares in the offering, including the Initiating Holders, in proportion (as nearly as practicable) to the amount of Registrable Securities of the Company owned by each Holder; provided, however, that the number of shares of Registrable Securities to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting. (c) Notwithstanding the foregoing, (i) the Company shall have the right to defer taking action with respect to a request for registration pursuant to this Section 1.2, where such request is received at any time during the period beginning ninety (90) days prior to the filing of any other registration statement (for the Company's account or otherwise) relating to an underwritten public offering of the Company's securities and ending ninety days (90) following the effective date of such registration statement (or, if such registration statement does not become effective, ninety days (90) following the withdrawal of such registration statement or the date such registration statement is deemed abandoned), until the conclusion of such period and (ii) if the Company shall furnish to Holders requesting a registration statement pursuant to this Section 1.2 a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such registration statement to be filed and it is therefore essential to defer the filing of such registration statement, the Company shall have the right to defer taking action with respect to such filing for a period of not more than one hundred eighty (180) days after receipt of the request of the Initiating Holders; provided, however, that the Company may not utilize the right set forth in (ii) above more than once in any twelve (12) month period. (d) The Company is obligated to effect only two (2) such registrations pursuant to this Section 1.2. 4 1.3 Company Registration. -------------------- (a) If the Company proposes to register (including for this purpose a registration effected by the Company for stockholders other than the Holders and including for this purpose a registration effected by the Company upon exercise of a demand right contained in Section 1.2 of this Agreement) any of its stock or other securities under the Act in connection with the public offering of such securities solely for cash (other than a registration relating solely to the sale of securities to participants in a Company stock plan or a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities), the Company shall, at such time, promptly give each Holder written notice of such registration. Upon the written request of each Holder given within twenty (20) days after mailing of such notice by the Company in accordance with Section 3.5, the Company shall, subject to the provisions of Section 1.8, include in the registration statement all of the Registrable Securities that each such Holder has requested to be registered. (b) Upon any sale by the Company of shares of its Common Stock to the public in a firmly underwritten public offering solely for cash, (i) the Key Stockholders and (ii) any employee officers and employee directors of the Company holding individually not less than one percent (1%) of the shares of the outstanding Common Stock (on a fully diluted basis) of the Company on the date notice is provided to each Holder pursuant to subsection 1.3(a) shall be entitled to include any of their shares of Common Stock in any registration by the Company under this subsection 1.3, if (A), for purposes of (ii) above only, such persons who choose to include any of their securities in such registration shall continue to serve the Company as employee officers or employee directors on the effective date of such registration statement, and (B) such persons agree to be bound by all other provisions of this Agreement and participate in any such registration on the same basis as each Holder (except as specifically set forth in Section 1.8 below) in accordance with all applicable provisions of this Agreement. 1.4 Obligations of the Company. Whenever required under this -------------------------- Section 1 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible: (a) Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for a period of up to ninety (90) days. (b) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection 5 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. (c) Furnish to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them. (d) 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 the Holders; 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. (e) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement. (f) Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Act 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 a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. (g) Cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by the Company are then listed. 1.5 Furnish Information. ------------------- (a) It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 1 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be required to effect the registration of such Holder's Registrable Securities. 6 (b) The Company shall have no obligation with respect to any registration requested pursuant to Section 1.2 or Section 1.12 if, due to the operation of subsection 1.5(a), the number of shares or the anticipated aggregate offering price of the Registrable Securities to be included in the registration does not equal or exceed the number of shares or the anticipated aggregate offering price required to originally trigger the Company's obligation to initiate such registration as specified in subsection 1.2(a) or subsection 1.12(b)(2), whichever is applicable. 1.6 Expenses of Demand Registration. All expenses other than ------------------------------- underwriting discounts and commissions incurred in connection with registrations, filings or qualifications pursuant to Section 1.2 and fees and disbursements of any counsel for the Holders, including (without limitation) all registration, filing and qualification fees, printers' and accounting fees, and fees and disbursements of counsel for the Company shall be borne by the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 1.2 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all participating Holders shall bear such expenses), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to one demand registration pursuant to Section 1.2; provided further, however, that if at the time of such withdrawal, the Holders have learned of a material adverse change in the condition, business, or prospects of the Company from that known to the Holders at the time of their request and have withdrawn the request with reasonable promptness following disclosure by the Company of such material adverse change, then the Holders shall not be required to pay any of such expenses and shall retain their rights pursuant to Section 1.2. 1.7 Expenses of Company Registration. The Company shall bear and -------------------------------- pay all expenses incurred in connection with any registration, filing or qualification of Registrable Securities with respect to the registrations pursuant to Section 1.3 for each Holder (which right may be assigned as provided in Section 1.13), including (without limitation) all registration, filing, and qualification fees, printers and accounting fees relating or apportionable thereto and the fees and disbursements of counsel for the Company for this purpose, but excluding underwriting discounts and commissions relating to Registrable Securities and the fees and disbursements of any counsel for the Holders. 1.8 Underwriting Requirements. In connection with any offering ------------------------- involving an underwriting of shares of the Company's capital stock, the Company shall not be required under Section 1.3 to include any of the Holders' securities in such underwriting unless they accept the terms of the underwriting as agreed upon between the Company and the underwriters selected by it, and then only in such quantity as the underwriters determine in their sole discretion will not adversely affect their ability to market the offering. If the underwriters determine that 7 marketing factors require a limitation of the number of shares to be underwritten, the underwriters may exclude from such underwriting all or some of the shares proposed for registration on behalf of Holders, and other stockholders, on the following basis: (a) shares held by any person who does not have contractual rights to cause the Company to register such shares shall first be excluded; (b) if further reductions are required, the Registrable Securities of any Holder electing to include shares in the offering will next be excluded, such reductions to be allocated as nearly as practicable among each such Holder in proportion to the number of shares that such Holder requests to be registered bears to the total number of shares that all Holders request to be registered; provided, however, that in a demand registration pursuant to Section 1.2 of this - -------- ------- Agreement, all shares held by Key Stockholders exercising piggyback registration rights under Section 1.3 of this Agreement shall be excluded from the offering before exclusion of any shares held by an Investor participating in such demand registration. Notwithstanding the foregoing, in no event shall any shares being sold by a stockholder exercising a demand registration right similar to that granted in Section 1.2 be excluded from such offering. 1.9 Delay of Registration. No Holder shall have any right to --------------------- obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 1. 1.10 Indemnification. --------------- (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, any underwriter (as defined in the Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Act or the 1934 Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Act, or the 1934 Act or other federal or state securities law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a "Violation"): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Act, the 1934 Act, any state securities law or any rule or regulation promulgated under the Act, or the 1934 Act or any state securities law; and the Company will pay to each such Holder, 8 underwriter or controlling person, as incurred, any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this subsection 1.10(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder, underwriter or controlling person. (b) To the extent permitted by law, each selling Holder will indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company within the meaning of the Act, any underwriter, any other Holder selling securities in such registration statement and any controlling person of any such underwriter or other Holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons may become subject, under the Act, the 1934 Act or other federal or state securities law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will pay, as incurred, any legal or other expenses reasonably incurred by any person intended to be indemnified pursuant to this subsection 1.10(b), in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this subsection 1.10(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided, that, in no event shall any indemnity under this subsection 1.10(b) exceed the net proceeds from the offering received by such Holder. (c) Promptly after receipt by an indemnified party under this Section 1.10 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 1.10, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid 9 by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 1.10, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 1.10. (d) The obligations of the Company and Holders under this Section 1.10 shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 1, and otherwise. 1.11 Reports Under Securities Exchange Act of 1934. With a view to --------------------------------------------- making available to the Holders the benefits of Rule 144 promulgated under the Act and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to: (a) make and keep public information available, as those terms are understood and defined in SEC Rule 144, at all times after the effective date of the first registration statement filed by the Company for the offering of its securities to the general public; (b) take such action, including the voluntary registration of its Common Stock under Section 12 of the 1934 Act, as is necessary to enable the Holders to utilize Form S-3 for the sale of their Registrable Securities, such action to be taken as soon as practicable after the end of the fiscal year in which the first registration statement filed by the Company for the offering of its securities to the general public is declared effective; (c) file with the SEC in a timely manner all reports and other documents required of the Company under the Act and the 1934 Act; and (d) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement filed by the Company), the Act and the 1934 Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other 10 information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the selling of any such securities without registration or pursuant to such form. 1.12 Form S-3 Registration. In case the Company shall receive --------------------- from any Holder or Holders a written request or requests that the Company effect a registration on Form S-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, the Company will: (a) promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders; and (b) as soon as practicable, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holder's or Holders' Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance, pursuant to this Section 1.12: (1) if Form S-3 is not available for such offering by the Holders; (2) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public (net of any underwriters' discounts or commissions) of less than $1,000,000; (3) if the Company shall furnish to the Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such Form S-3 Registration to be effected at such time, in which event the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than one hundred fifty (150) days after receipt of the request of the Holder or Holders under this Section 1.12; provided, however, that the Company shall not utilize this right more than once in any twelve (12) month period; (4) if the Company has, within the twelve (12) month period preceding the date of such request, already effected one (1) registration on Form S-3 for the Holders pursuant to this Section 1.12; (5) if the Company has already effected a total of six (6) registrations on Form S-3 for the Holders pursuant to this Section 1.12; or (6) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance. (c) Subject to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request or requests of the 11 Holders. All expenses incurred in connection with the first four registrations requested pursuant to this Section 1.12, including (without limitation) all registration, filing, qualification, printer's and accounting fees and the reasonable fees and disbursements of counsel for the Company, but excluding any underwriters' discounts or commissions associated with Registrable Securities and the fees and disbursements of any counsel for the Holders, shall be borne by the Company; the participating Holders shall bear all expenses of any additional registrations under this Section 1.12. Registrations effected pursuant to this Section 1.12 shall not be counted as demands for registration or registrations effected pursuant to Sections 1.2 or 1.3, respectively. 1.13 Assignment of Registration Rights. The rights to cause the --------------------------------- Company to register Registrable Securities pursuant to this Section 1 may be assigned (but only with all related obligations) by a Holder that is a limited partnership to any affiliated limited partnership that is managed by the same management company or managing partner or by a person or entity controlling, controlled by or under common control with, such management company or managing partner, or by a Holder that is a corporation to any entitiy that directly or indirectly controls the Holder or is directly or indirectly controlled by the Holder who, after such assignment or transfer, holds at least 200,000 shares of Registrable Securities (subject to appropriate adjustment for stock splits, stock dividends, combinations and other recapitalizations), or, in the case of an Investor that is a trust, to any grantor or beneficiary of such trust, or in the case of an individual to any lineal ancestor, lineal descendant or spouse; provided the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; and provided, further, that such assignment shall be effective only if immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the Act. For purposes of the foregoing sentence, "control" shall mean either (i) service as or the ability to appoint a director of any entity, or (ii) ownership of at least 10% of the outstanding equity of an entity. For the purposes of determining the number of shares of Registrable Securities held by a transferee or assignee, the holdings of transferees and assignees of a partnership who are partners or retired partners of such partnership (including spouses and ancestors, lineal descendants and siblings of such partners or spouses who acquire Registrable Securities by gift, will or intestate succession) shall be aggregated together and with the partnership; provided that all assignees and transferees who would not qualify individually for assignment of registration rights shall have a single attorney-in-fact for the purpose of exercising any rights, receiving notices or taking any action under this Section 1. 1.14 Limitations on Subsequent Registration Rights.

(b) The covenants set forth in Section 2.1, Section 2.4 and Section 2.7 shall terminate as to Investors and be of no further force or effect upon the consummation of the sale of securities pursuant to a registration statement filed by the Company under the Act in connection with a firm commitment underwritten offering of its securities to the general public that triggers the conversion of all outstanding shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock pursuant to Section 4(b) of ARTICLE FOURTH of the Company's Certificate of Incorporation. 2.4 Right of First Offer. Subject to the terms and conditions -------------------- specified in this paragraph 2.4, the Company hereby grants to each Major Investor (as hereinafter defined) a right of first offer to purchase its Pro Rata Share (as hereinafter defined) (in whole or in part) with respect to future sales by the Company of its Shares (as hereinafter defined) to be sold. For purposes of this Section 2.4, the term Major Investor shall include each Investor and Alex Pinchev, Dieter Riffel, Formula Ventures L.P., Formula Ventures (Israel) L.P., FV-PEH L.P. and USU Sofwarehaus Unternehmensberatung. Each Major Investor shall be entitled to assign or apportion the right of first offer hereby granted it among itself and its partners and affiliates (including in the case of a venture capital fund other venture capital funds affiliated with such fund) in such proportions as it deems appropriate. For purposes of this Section 2.4, a Major Investor's Pro Rata Share of Shares shall mean that number of Shares that equals the proportion that the number of shares of Common Stock issued and held, or issuable upon conversion of the Preferred Stock then held, by such Major Investor bears to the total number of shares of Common Stock issued and held, or issuable upon conversion of the Preferred Stock then held, by all the Major Investors. Each time the Company proposes to offer any shares of, or securities convertible into or exercisable for any shares of, any class of its capital stock ("Shares"), the Company shall first make an offering of such Shares to each Major Investor in accordance with the following provisions: (a) The Company shall deliver a notice by facsimile or certified mail ("Notice") to the Major Investors stating (i) its bona fide intention to offer such Shares, (ii) the number of such Shares to be offered, (iii) the price and a summary of the terms, if any, upon which it proposes to offer such Shares and (iv) each Major Investor's Pro Rata Share. (b) By written notification received by the Company within fifteen (15) business days after receipt of the Notice, each Major Investor may elect to purchase or obtain, at the price and on the terms specified in the Notice, up to its Pro Rata Share of such Shares. For purposes of this Section 2.4, each Major 15 Investor that purchases its Pro Rata Share of the Shares shall be a "Fully- Exercising Investor." If so specified in writing by a Fully-Exercising Investor within the same fifteen (15) day period as referred to above, such Fully- Exercising Investor may elect to purchase or obtain, in addition to its Pro Rata Share of the Shares and at the price and on the terms specified in the Notice, up to its Over-allotment Portion (as defined below) of the Shares. For purposes of this Section 2.4, a Fully-Exercising Investor's Over-allotment Portion shall be that portion of the Shares not subscribed for by the Major Investors that is equal to the proportion that the number of shares of Common Stock issued and held, or issuable upon conversion of Preferred Stock then held, by such Fully- Exercising Investor bears to the total number of shares of Common Stock issued and held, or issuable upon conversion of the Preferred Stock then held, by all Fully-Exercising Investors who wish to purchase some of the unsubscribed shares. (c) If all Shares that the Major Investors are entitled to obtain pursuant to subsection 2.4(b) are not elected to be obtained as provided in subsection 2.4(b) hereof, the Company may, during the sixty (60)-day period following the expiration of the period provided in subsection 2.4(b) hereof, offer the remaining unsubscribed portion of such Shares to any person or persons at a price not less than, and upon terms no more favorable to the offeree than those specified in the Notice. If the Company does not enter into an agreement for the sale of the Shares within such period, or if such agreement is not consummated within thirty (30) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such Shares shall not be offered unless first reoffered to the Major Investors in accordance herewith. (d) The right of first offer in this paragraph 2.4 shall not be applicable (i) to shares of Common Stock issuable or issued to employees, consultants, directors or vendors (if in transactions with primarily non- financing purposes) of the Company directly or pursuant to a stock option plan or restricted stock plan approved by the Board of Directors, (ii) to shares of Common Stock issued or issuable in a firm commitment underwritten public offering in connection with which all outstanding shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock will be converted to Common Stock, (iii) to shares of Common Stock issued or issuable upon conversion of shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock, (iv) to securities issued or issuable to banks or equipment lessors, provided such issuances are for other than primarily equity financing purposes and (v) to securities issued in connection with business combinations or corporate partnering agreements approved by the Board of Directors. 2.5 Automatic Termination of Paragraphs 2.1, 2.3 and 2.4. Upon the ---------------------------------------------------- closing of an initial public offering by the Company of its Common Stock, provided that the following shall not be considered a public offering: (i) any issuance 16 of Common Stock as consideration for a merger, acquisition or SEC Rule 145 transaction, and (ii) to employees of the Company or its Subsidiaries on Form S-4 or Form S-8 (or any successor forms adopted by the Securities and Exchange Commission) or otherwise, irrespective of the jurisdiction in which the initial public offering is conducted, or at the latest time prior to such closing, if required by the principal securities exchange or market upon which the Common Stock will be listed or traded, this Agreement, automatically without further action, is hereby amended by deleting paragraphs 2.1, 2.3 and 2.4 in their entirety. 2.6 Key-Man Insurance. The Company shall maintain term life ----------------- insurance on the life of Alex Pinchev in an amount of at least $2 million from a financially sound and reputable insurer. Such policy shall name the Company as loss payee with respect to such $2 million. The key man life insurance shall not be cancelable by the Company without prior approval of the Board of Directors. 2.7 Proprietary Information and Inventions Agreements. The Company ------------------------------------------------- will cause each consultant and each person now or hereafter employed by it or any subsidiary with access to confidential information to enter into a Proprietary Information and Inventions Agreement in substantially the form approved by the Board of Directors. 17 3. Miscellaneous. ------------- 3.1 Successors and Assigns.

If one or more provisions of this Agreement are ------------ held to be unenforceable under applicable law, such provision shall be excluded from this Agreement, and the balance of the Agreement shall be interpreted as if such provision were so excluded, and shall be enforceable in accordance with its terms. 3.9 Aggregation of Stock.
