8.1 Demand Registration. If, on or after the earlier to occur of December 31, 2000, or the expiration of 180 days after the Company shall have first offered its securities pursuant to a registration under the 1933 Act, Initiating Holders shall notify the Company in writing that such Holders intend to offer or cause to be offered for sale to the public all or any portion of the Registrable Securities under such circumstances as would require registration thereof under the 1933 Act or qualification thereof under one or more state securities laws of jurisdictions in which the offer is to be made, the Company will, as expeditiously as possible, (i) notify Holders other than the Initiating Holders that it has been requested to register Registrable Securities under the 1933 Act pursuant to this Section 8.1, and (ii) use its best efforts to cause such securities as may be requested by any Holder thereof to be registered under the 1933 Act, if applicable, and registered or qualified under any state securities laws to the extent required (in the opinion of counsel referred to in this Section 8.1) to permit the sale or other disposition thereof in the manner described by the person requesting such registration. The Holders shall have a total of four such rights to demand registration of Registrable Securities under this Section 8.1. In addition to the above-described demand registration rights, the holders of Preferred Stock of the Company shall have a total of two rights to demand registration of Registrable Securities held by them under this Section 8.1.

The Company (together with all Holders and Other Holders proposing to include their securities in such registration) shall enter into an underwriting agreement in customary form with the underwriter or representative of the underwriters (the “Underwriter”) selected to underwrite such offering by a majority in interest of

- 19 -

the Initiating Holders, subject to the approval of the Company, which approval shall not be unreasonably withheld. Notwithstanding any other provision of this Section 8.1, if the underwriter advises the Initiating Holders in writing that marketing factors require a limitation on the number of shares to be underwritten, the Initiating Holders shall so advise all Holders and Other Holders whose securities would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among all Holders in proportion, as nearly as practicable, to the Respective amounts of Registrable Securities which they had requested to be included in such registration and underwriting at the time of filing the registration statement, and to the extent that additional shares may be included in the underwriting, among all Other Holders requesting such inclusion in proportion, as nearly as practicable, to the respective amount of securities which they had requested to be included in such registration and underwriting. No Registrable Securities or other securities excluded from the underwriting by reason of the Underwriter’s marketing limitations shall be included in such registration. If any Holder or Other Holder who has requested inclusion in such registration as provided herein disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company, the Underwriter and the Initiating Holders. The securities so withdrawn shall also be withdrawn from registration. If the Underwriter has not limited the number of Registrable Securities or other securities to be underwritten, the Company may include its securities for its own account in such registration if the Underwriter so agrees and if the number of Registrable Securities which would otherwise have been included in such registration and underwriting will not thereby be limited.

The registration of Registrable Securities under this Section 8.1 shall be at the Company’s expense, except that Holders and Other Holders participating in a registration pursuant hereto shall pay their pro rata brokerage or underwriting commissions or discounts relating to the sale owned by them; and the Company shall also pay the fees and expenses of any one special counsel retained by such Holders or Other Holders and except that after the second demand registration under this Section 8.1 demand registrations shall be at the expense of the Holders participating in the registration.

Initiating Holders who exercise a right to demand registration under this Section 8.1 may withdraw the exercise and cause the Company either not to file or to withdraw the filing of the registration statement at anytime prior to the effectiveness of such statement, provided that:

(i) If the exercise is so withdrawn prior to filing of the registration statement, then the withdrawal of the exercise will not be deemed to have been the exercise of a demand registration right;

(ii) If effectiveness of the registration statement is delayed by more than 90 days by the Company and the exercise is withdrawn prior to effectiveness of the registration statement, then the withdrawal of the exercise will not be deemed to have been the exercise of a demand registration right;

- 20 -

(iii) Any withdrawals other than the withdrawals specified in (i) and (ii) above shall be deemed to be a demand pursuant to Section 8.1 hereof. If the withdrawn demand registration right is not deemed to have been the exercise of a demand registration right, as provided in subparagraphs (i) and (ii) above, then the withdrawing Holder shall pay or reimburse the legal, auditing and printing expenses reasonably incurred by the Company in connection with the attempted registration; but if the withdrawn demand registration right is deemed to be an exercise as provided in subparagraph (iii) above, then the Company shall pay all expenses incurred by it in connection with the attempted registration if the Company would have been responsible for paying the expenses of preparation of such registration statement

8.2 Company Registration. If, at any time, the Company proposes to register under the 1933 Act, or register or qualify under the laws of any state, any of its Common Stock or securities convertible into or exercisable for Common Stock, on a form under the 1933 Act permitting registration of secondary offerings, it will each such time give written notice of its intention to do so to each of the Holders. In the case of the registration for the initial public offering of the Company’s stock, the Company will give the Holders at least 30 days prior written notice of the proposed filing of the registration statement; and in the case of all subsequent registrations, the Company will give the Holders at least 20 days prior written notice of such proposed filing. If a Holder desires to participate in such registration or qualification of Common Stock, or other securities, it shall notify the Company, within 20 days in the case of the initial registration and 15 days in the case of subsequent registrations, of the number of shares of Registrable Securities which it desires to have so included. In the event the Company decides to proceed with such registration or qualification, the Company will, at its sole expense, use its best efforts to cause all such Registrable Securities to be registered or qualified to permit the sale thereof; provided, however, that if, in connection with the offering by the Company of Common Stock, or securities convertible into or exercisable for Common Stock, pursuant to a registration under the 1933 Act, the underwriter thereof shall impose a limitation on the number of shares of the Company’s stock or securities which may be included in any such registration statement because, in its judgment, the inclusion of such shares would materially and adversely affect such public offering, then the Company shall be obligated to include in such registration statement only such portion of the Registrable Securities requested to be registered under this Section 8 as the underwriter permits; provided that all other securities other than those offered for the Company’s own account shall first be excluded from the registration statement and provided further that not more than 65% of the shares to be included in such registration statement shall be shares to be sold by the Company except that the Company may include greater than 65% of the shares to be included in such registration to the extent the aggregate of all such shares to be included therein, after allowing therein all securities offered other than by the Company, is less than the total number of shares permitted to be included by the underwriters. Such limitation will be imposed pro rata with respect to all Registrable Securities as to which inclusion has been requested pursuant to this Section 8.2. The Company shall bear all of the expense of all registrations pursuant to this Section 8.2, except for the pro rata portion of brokerage or underwriters discounts or commissions relating to the shares sold on behalf of the Holders or Other Holders and the fees and expenses of any one special counsel retained by such Holders or Other Holders. It shall not be deemed a default of this Agreement if any such underwriter shall (a) establish a limitation on the number of shares allowed to participate in any public offering of the Company’s stock which are not being sold for the Company’s account (subject to the 65% limitation referred to above), or (b) shall require the holders of the Company’s stock, other than the Company, to agree to refrain from selling their stock to members of the public for some reasonable period of time (no longer than 180 days) after the date on which the Company’s stock is first offered to the public (so called lock-up provisions), or (c) shall establish any other reasonable limitations or restrictions applicable to the holders of the Company’s stock, as a condition to consummating the public offering.

8.3 Registration on Form S-3. Following the first offering of its securities by the Company pursuant to a registration under the 1933 Act, the Company shall use its reasonable efforts to qualify for registration of its Common Stock under the 1933 Act on Form S-3 (or any successor form of similar tenor and effect). If the Company shall be able to satisfy the conditions for registration of its Common Stock under the 1933 Act on Form S-3 (or any successor form of similar tenor and effect), then, in addition to other rights of the Holders hereunder, the Company will, upon written request of Holders seeking to register on Form S-3 Registrable Securities having an aggregate market value of at least $500,000, as expeditiously as possible, endeavor in good faith to effect a registration under the 1933 Act on Form S-3 (or any successor form of similar tenor and effect) of all Registrable Securities referred to in a request or notice given to the Company pursuant to this Section 8.2 and to effect any registration or qualifications of such Registrable Securities under any state law, and any listing of such Registrable Securities with any securities exchange on which the Common Stock of the Company is then listed, which may be required to permit the sale or disposition of such Registrable Securities in the manner specified in such request or notices; provided, however, that no more than once per year the Company may meet its obligations under this Section 8.3 by preparing its own registration of securities on any applicable form under the 1933 Act, which registration becomes effective within 90 days after such request or notice and which registration includes all Registrable Securities referred to in such request or notice. If Registrable Securities sold pursuant to this Section 8.3 are sold in an underwritten offering, the terms of the underwriting agreement with the underwriter shall be mutually satisfactory to the Company and the Holders requesting registration hereunder. The Company shall not be required to effect more than two registrations pursuant to this Section 8.3 within any twelve month period.

The registration of Registrable Securities under this Section 8.3 shall be at the Company’s expense, except that Holders participating in a registration pursuant hereto shall pay their pro rata brokerage or underwriting commissions or discounts relating to the sale of Common Stock owned by them and shall pay the fees and expenses of any one special counsel retained by such Holders or Other Holder.

8.4 Rule 144 Requirements. Within 90 days following the first offering of its securities by the Company pursuant to a registration under the 1933 Act, the Company shall become and shall thereafter, so long as is necessary to permit the Holders to sell stock pursuant to Rule 144 under the 1933 Act, or any successor exemptive rule of similar tenor hereafter in effect (“Rule 144”), remain subject to the reporting requirement of either Section 13 or Section 15(d) of the Securities Exchange Act of 1934. At all times when the Company is subject to such reporting requirements, the Company shall use its best efforts to file with the Securities and Exchange Commission such information as the Commission may require under either of said Sections, and shall exercise its best efforts to take all action as may be required to fulfill the conditions to the availability of Rule 144 for sales of Common Stock of the Company. The Company shall furnish to each Holder, upon its reasonable request, a written statement executed by the Company as to the steps it has taken to comply with the current public information requirement of Rule 144.

8.5 Transfer Where Registration Not Required. Before transferring, without registration under the 1933 Act or any state securities laws, any security bearing a legend pursuant to Section 8.4, the Holder thereof shall give written notice to the Company of its intention to do so, describing briefly the manner of the disposition to be made thereof. Promptly upon receiving such written notice, the Company shall present copies thereof to its counsel and if, in the opinion of such counsel, the proposed disposition of such securities may be effected without registration or qualification thereof (under all applicable Federal or state laws), the Company, as promptly as practicable, shall notify such Holder of such opinion, whereupon the Holder shall be entitled to dispose of such security in accordance with the terms of the notice delivered by it to the Company.

8.6 Conversion Prior to Sale. Notwithstanding anything contained herein to the contrary, the obligations of the Company under this Section 8 to effect any registration, qualification, notification, or approval shall be limited to Common Stock only. No Holder shall be required to convert Shares to Common Stock prior to requesting any such registration, qualification, notification, or approval, but any such security included therein shall be so converted no later than the date on which such Holder effects a sale thereof pursuant to such registration, qualification, notification, or approval.

8.7 Filing Services of the Company. In connection with any registration, filings or sales effected under Section 8.1, 8.2 or 8.3 hereof, the Company will:

8.7.1 Prepare and file the registration statement and such amendments and supplements to the registration statement and the prospectus and/or offering circular used in connection therewith as may be necessary to keep the registration statement and/or notification effective for a period of not less than one hundred and eighty (180) days, as may be necessary for the Holders whose Registrable Securities are registered thereunder to dispose thereof and to comply with the provisions of the 1933 Act and applicable state securities laws with respect to the deposition of the securities covered by the registration statement and/or notification whenever such selling Holder shall dispose of such securities during such period;

8.7.2 Furnish to such selling Holder, if applicable, such reasonable number of copies of a prospectus or offering circular, including a preliminary prospectus, in conformity with the requirements of the 1933 Act and regulations thereunder, as such selling Holder may reasonably request in order to facilitate the disposition of such securities;

8.7.3 Use its best efforts to register or qualify the securities covered by the registration statement under the securities laws of such jurisdictions as such selling Holder shall reasonably request (to the extent required, in the opinion of counsel referred to in Section 8.5 and provided such filing is not unreasonably burdensome on the Company), and accomplish any and all other acts which may be reasonably necessary or advisable to enable such selling Holder to consummate the disposition in such jurisdictions of the securities owned by it or him; provided, however that the Company shall not be required to qualify as a foreign corporation in any such jurisdictions or escrow shares of its capital stock or file any general consent to service of process under the laws of any such jurisdiction;

- 23 -

8.7.4 Furnish to each selling Holder a signed counterpart, addressed to the selling Holder, of

(i) an opinion of counsel for the Company, dated the effective date of the registration statement, and

(ii) “comfort” letters signed by the Company’s independent public accountants who have examined and reported on the Company’s financial statements included in the registration statement, to the extent permitted by the standards of the AICPA,

covering substantially the same matters with respect to the registration statement (and the prospectus included therein) and (in the case of the accountants “comfort” letters) with respect to events subsequent to the date of the financial statements, as are customarily covered in opinions of issuer’s counsel and in accountants, “comfort” letters delivered to the underwriters in underwritten public offerings of securities, to the extent that the Company is required to deliver or cause the delivery of such opinion or “comfort” letters to the underwriters in an underwritten public offering of securities;

8.7.5 Permit each selling Holder or his or its counsel or other representatives to inspect and copy such corporate documents and records as may reasonably be requested by them;

8.7.6 Furnish to each selling Holder a copy of all documents filed and all correspondence from or to the Securities and Exchange Commission in connection with any such offering; and

8.7.7 Indemnify each selling Holder, each officer and director of such Holder and each person, if any, who controls such Holder, within the meaning of applicable Federal and state securities laws (the “Applicable Securities Laws”) against all losses, claims, damages, liabilities, and expenses (under the Applicable Securities Laws, or common law or otherwise) resulting from any untrue statement or alleged untrue statement or a material fact contained in any registration statement or prospectus (and as amended or supplemented if the Company shall have furnished to the selling Holder any amendments or supplements thereto) or resulting from any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made, except insofar as such losses, claims, damages, liabilities or expenses result from any untrue statement or omission contained in information furnished in writing to the Company by the Holder expressly for use therein. If the offering pursuant to any registration statement provided for under Section 8.1, 8.2 or 8.3 is made by underwriters, the Company agrees to negotiate in good faith the terms of an underwriting agreement with such underwriters and, to enter into such agreement once the terms thereof are agreed upon and, if required by such terms, to indemnify such underwriters and each person who controls such underwriters within the meaning of the Applicable Securities Laws in substantially the same manner as hereinabove provided with respect to the indemnification of the selling Holder. In connection with any registration statement in which a Holder is participating, such Holder will furnish to the Company in writing such information as shall be reasonably requested by the Company for use in any such registration statement or prospectus, will notify the Company as to any changes therein, and will indemnify the Company, its directors, its officers, and each person, if any, who

- 24 -

controls the Company within the meaning of the Applicable Securities Laws, and, if required by the terms of an agreement with such underwriters, such underwriters and each person who controls such underwriters within the meaning of the Applicable Securities Laws, against any losses, claims, damages, liabilities, and expense resulting from any untrue statement or alleged untrue statement of a material fact or any omission or alleged omission of material fact required to be stated in the registration statement or prospectus (or any amendment or supplement thereof) and necessary to make the statements therein not misleading in light of the circumstances under which they were made, but only to the extent that such untrue statement or omission is contained in the information so furnished in writing by the Holder expressly for use therein.

In order to provide for just and equitable contribution to joint liability under the 1933 Act in any case in which either:

(i) Any Holder of Registrable Securities exercising rights under this Section 8, or any controlling person of any such person, make a claim for indemnification pursuant to this section but it is judicially determined (by the entry of a final judgement or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this subsection provides for indemnification in such case; or

(ii) Contribution under the 1933 Act may be required on the part of any such selling Holder or any such controlling person in circumstances for which indemnification is provided under this section;

then, and in each such case, the Company and such selling Holder will contribute to the aggregate losses, claims, damages, or liabilities to which they may be subject (after contribution from others) in such proportion so that such selling Holder is responsible for the portion represented by the percentage that the purchase price of its Common Stock bears to the public offering price of all such Common Stock offered by such registration statement, and the Company is responsible for the remaining portion; provided, however, that, in any such case, (A) no selling Holder will be required to contribute any amount in excess of the purchase price of all such Common Stock offered by it pursuant to such registration statement, and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 0000 Xxx) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation.

Promptly after receipt by any party to this Agreement of notice of the commencement of any action, suit or proceeding, such party will, if a claim for contributing in respect thereof is to be made against another party, notify the contributing party of the commencement thereof. The omission to so notify the contributing party will not relieve it from any liability which it may have to any other party other than for contribution under the 1933 Act. In any case, if such action, suit or proceeding is brought against any party, and such party notifies a contributing party of the commencement thereof, the contributing party will be entitled to participate therein with the notifying party and any other contributing party similarly notified. The Company shall not be liable for any settlement entered into by any Holder without the Company’s consent.

- 25 -

8.8 Certain Limitation in Connection with Future Grants of Registration Rights. From and after the date of this Agreement and while any Registrable Securities or securities issued upon conversion thereof remain outstanding, the Company shall not enter into any agreement with any holder or prospective holder of any securities of the Company which grants to such holder registration rights with respect to any of the Company’s securities unless such agreement provides that:

(i) In the reasonable opinion of the Board of Directors of the Company, such rights are no more extensive or favorable to such purchasers than the demand and other registration rights granted to the Holders;

(ii) The Holders shall have the right to participate in registrations pursuant to the exercise of such rights on a pro rata basis; and

(iii) Such rights relate only to Common Stock of the Company.

8.9 Transfer of Registration Rights.

Molvig and Xxxxxxxx (including without limitation any partner of any investor which is a partnership or any estate or trust of which any Investor which is an individual is the grantor) provided, however, that the Company is given written notice by the Holder at the times of such transfer stating the name and address of the transferee and identifying the securities with respect to which the rights under this Section 8 are being transferred.

8.10 Exchange Act Registration. If the Company at any time shall list any Common Stock on any national securities exchange and shall register such Common Stock under the Securities Exchange Act of 1934 the Company will, at its expense, simultaneously list on such exchange and maintain such listing of, all of the shares of Common Stock included in the definition of Registrable Securities.

8.11 Damages. The Company recognizes and agrees that the selling Holders will not have an adequate remedy if the Company fails to comply with this Section 8 and that damages will not be readily ascertainable, and the Company expressly agrees that, in the event of such failure, it shall not oppose an application by such selling Holder or any other person entitled to the benefits of this Section 8 requiring specific performances of any and all provisions hereof or enjoining the Company from continuing to commit any such breach of this Section 8.

8.12 Termination of Registration Rights. The provisions of this Section 8 shall terminate on the fifth anniversary of the Company’s first Qualified Public Offering.
