(a) Timing of Demand Registrations. At any time after the date hereof, upon the earlier to occur of (1) June 14, 2002 or (2) the effective date of a Registration Statement relating to a public offering of the Company's Common Stock, the holders of at least 50% of the Preferred Registrable Securities (on behalf of themselves and all permitted assignees who are holders of Preferred Registrable Securities) may request at any time that the Company file a Registration Statement under the Securities Act on an appropriate form (which form shall be available for the sale of the Registrable Securities in accordance with the intended method or methods of distribution thereof and shall include all financial statements required by the SEC to be filed therewith) covering the shares of Preferred Registrable Securities that are the subject of such request.

(b) Number of Demand Registrations; Required Threshold. The Company shall be obligated to prepare, file and use its best efforts to cause to become effective pursuant to this Section 2 no more than two (2) Registration Statements in the aggregate for the holders of Preferred Registrable Securities (on behalf of each of them and all permitted assignees who are holders of Preferred Registrable Securities); provided, however, that a Registration Statement shall not be counted as one of the two (2) Demand Registrations hereunder of such holders of Preferred Registrable Securities unless (1) it becomes effective and is maintained effective in accordance with the requirements specified in SECTION 5(a) or (2) it is filed on Form S-3 under the Securities Act. The Company shall be obligated to prepare, file and use its best efforts to cause to become effective pursuant to this SECTION 2 up to two (2) Registration Statements on Form S-3 per year, subject to SECTION 2(a).

(c) Participation. The Company shall promptly give written notice to all holders of Preferred Registrable Securities and all Stockholders of Future Registrable Securities and Warrant Registrable Securities, upon receipt of a request for a Demand Registration pursuant to SECTION 2(a), above. In addition, the Company shall include in such Demand Registration such shares of Series C Registrable Securities, Series E Registrable Securities, Future Registrable Securities and Warrant Registrable Securities for which it has received written requests to register such shares within twenty (20) calendar days after such written notice has been given. The holders of Preferred Registrable Securities exercising a Demand Registration request and the Stockholders of Future Registrable Securities and Warrant Registrable Securities participating in a Demand Registration shall receive priority with respect to the number of shares to be included in a Registration; provided, that such participation may be limited in the good faith judgment of the managing underwriter in an underwritten public offering in accordance with Section 2(d) below.

(d) Underwriter's Cutback. If the public offering of Registrable Securities is to be underwritten and, in the good faith judgment of the managing underwriter, the inclusion of all the Series C Registrable Securities, all Series E Registrable Securities, all the Future Registrable Securities and all the Warrant Registrable Securities requested to be registered hereunder would interfere with the successful marketing of a smaller number of such shares of Series C Registrable Securities, Series E Registrable Securities, Future Registrable Securities and Warrant Registrable Securities, then the number of shares of Series C Registrable Securities, Series E Registrable Securities, Future Registrable Securities and Warrant Registrable Securities, to be included shall be reduced to such smaller number, with the reduction in participation in such offering to be borne (i) first, by the Series C Stockholders of Series C Registrable Securities until, if necessary, no Series C Registrable Securities are included in such Registration and (ii) second, by the Series E Stockholders of Series E Registrable Securities and the Stockholders of Future Registrable Securities and Warrant Registrable Securities requesting such registration PRO RATA based upon the number of shares of Series E Registrable Securities, Future Registrable Securities and Warrant Registrable Securities, owned by such Stockholders.

The Company and, subject to the requirements of SECTION 11 hereof, other holders of securities of the Company may include such securities in such Registration if, but only if, the managing underwriter concludes that such inclusion will not interfere with the successful marketing of all the Series C Registrable Securities, Series E Registrable Securities, Future Registrable Securities and Warrant Registrable Securities requested to be included in such registration.

(e) Managing Underwriter. The managing underwriter or underwriters of any Underwritten Offering covered by a Demand Registration shall be selected by GE Capital Equity Investments, Inc. ("GE") (if GE owns a majority of the shares of Common Stock to be offered therein), subject to the approval of the Board of Directors, which approval shall not be unreasonably withheld.

3. Piggyback Registrations.

(a) Series C and Series E Participation. Each time the Company decides to file a Registration Statement under the Securities Act (other than registrations on Forms S-4 or S-8 or any successor form thereto, and other than a Demand Registration) covering the offer and sale by it or any of its security holders of any of its securities for money, the Company shall give written notice thereof to all holders of Preferred Registrable Securities and the Stockholders of Future Registrable Securities and Warrant Registrable Securities. The Company shall include in such Registration such shares of Preferred Registrable Securities, Future Registrable Securities and Warrant Registrable Securities for which it has received written requests to register such shares within twenty (20) calendar days after such written notice has been given. If the Registration Statement is to cover an Underwritten Offering, such Preferred Registrable Securities, Future Registrable Securities and Warrant Registrable Securities shall be included in the underwriting on the same terms and conditions as the securities otherwise being sold through the underwriters.

(b) Other Stockholders' Participation. If (but without any obligation to do so) the Company proposes to register (including for this purpose a registration effected by the Company for stockholders of the Company other than the Stockholders) any of its stock or other securities under the Securities Act in connection with the public offering of such securities solely for cash (other than (i) a registration relating solely to the sale of securities to participants in a Company stock option or stock issuance plan, (ii) a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities which are also being registered or (iii) the Company's first public offering of its Common Stock subsequent to March 2, 2001), then the Company shall, at such time, promptly give each Other Stockholder written notice of such registration. Upon the written request of each Other Stockholder given within twenty (20) calendar days after receipt of such notice by the Company in accordance with Section 15, the Company shall, subject to the provisions of SECTION 3(c), cause to be registered under the Securities Act all of the Registrable Securities that each such Other Stockholder has requested to be registered.

(c) Underwriter's Cutback. Subject to the requirements of SECTION 10 hereof, if in the good faith judgment of the managing underwriter of such offering, the inclusion of all of the shares of Registrable Securities and any other shares of Common Stock requested to be registered would interfere with the successful marketing of a smaller number of such shares, then the number of shares of Registrable Securities and other shares of Common Stock to be included in the offering shall be reduced to such smaller number, with the participation in such offering to be in the following order of priority: (1) first, the shares of Common Stock which the Company proposes to sell for its own account, (2) second, the shares of Series E Registrable Securities of all Series E Stockholders of Series E Registrable Securities, (3) third, the shares of Series C Registrable Securities of all Series C Stockholders of Series C Registrable Securities and the Future Registrable Securities and Warrant Registrable Securities of all Stockholders requested to be included, (4) fourth, the shares of Registrable Securities of Other Stockholders requested to be included, and (5) fifth, any other shares of Common Stock requested to be included. Any necessary allocation among the Holders of shares within each of

(2), (3), (4) and (5) above shall be PRO RATA among such Holders requesting such registration based upon the number of shares of Common Stock and Registrable Securities owned by such Holders.

(d) Company Control. The Company may withdraw a Registration Statement after filing and after giving notice to the Holders of Registrable Securities pursuant to SECTION 3(a), above, but prior to the effectiveness thereof; provided, that the Company shall promptly notify each Holder of Registrable Securities in writing of any such action; and provided further, that the Company shall bear all expenses incurred by each such Holder or otherwise in connection with such withdrawn Registration Statement.

4. Hold-Back Agreements. The Company agrees:

(a) not to effect any public or private sale or distribution of its Equity Securities during the thirty (30) calendar day period prior to, and during the sixty (60) calendar day period after, the effective date of each Underwritten Offering made pursuant to a Demand Registration or a Piggyback Registration, if so requested in writing by the managing underwriter (except as part of such Underwritten Offering, pursuant to registrations on Forms S-4 or S-8 or any successor forms thereto or private issuances of Equity Securities as consideration for any acquisition by the Company or a subsidiary of assets or capital stock of any unaffiliated third party), and

(b) not to issue any Equity Securities other than for sale in a registered public offering unless each of the Persons to which such securities are issued has entered a written agreement binding on its transferees not to effect any public sale or distribution of such securities (except for employee stock options issued to Persons other than: directors, officers, key employees; or stockholders owning five percent (5%) or more of the Company's Equity Securities) during such period, including without limitation a sale pursuant to Rule 144 under the Securities Act (except as part of such Underwritten Registration, if and to the extent permitted hereunder).

5. Registration Procedures.

If and whenever the Company is required to register Registrable Securities in a Demand Registration, the Company will use all commercially reasonable efforts to effect such registration to permit the sale of such Registrable Securities in accordance with the intended plan of distribution thereof. With respect to both Demand Registrations and Piggyback Registrations (except as otherwise specifically provided), the Company will as expeditiously as practicable:

(2) obtain opinions of counsel to the Company and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to the managing underwriter, if any, and each of such Holders (on behalf of itself and all permitted assignees who are Holders of Registrable Securities)) addressed to each selling Holder of Registrable Securities and the underwriter, if any, covering the matters customarily covered in opinions delivered to holders and underwriters, respectively, in similar underwritten offerings and such other matters as may be reasonably requested any of the Holders or such underwriters;

(3) obtain "cold comfort" letters and updates thereof from the Company's independent certified public accountants addressed to the selling Holders of Registrable Securities and the

underwriters, if any, such letters to be in customary form and covering matters of the type customarily covered in "cold comfort" letters to holders and underwriters, respectively, in connection with similar underwritten offerings;

(4) if an underwriting agreement is entered into, cause the same to include customary indemnification and contribution provisions and procedures with respect to such underwriters; and

(5) deliver such documents and certificates as may be reasonably requested by each of the Holders of Registrable Securities (on behalf of itself and all permitted assignees who are Holders of Registrable Securities) and the managing underwriter, if any, to evidence compliance with clause (1) above and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company.

The above shall be done at each closing under such underwriting or similar agreement or as and to the extent otherwise reasonably requested by each of the Holders of Registrable Securities (on behalf of itself and all permitted assignees who are Holders of Registrable Securities);

(p) make available for inspection by representatives of each of the Holders of Registrable Securities (on behalf of itself and all permitted assignees who are Holders of Registrable Securities), any underwriter participating in any disposition pursuant to such Registration Statement, and any attorney or accountant retained by the sellers or any such underwriter, all financial and other records and pertinent corporate documents and properties of the Company, and cause the Company's officers, directors and employees to supply all information reasonably requested by any such seller or underwriter in connection with the Registration; provided, that any records, information or documents that are designated by the Company in writing as confidential shall be kept confidential by such Persons unless disclosure of such records, information or documents is required by court or administrative order; and

(q) otherwise use all commercially reasonable efforts to comply with all applicable rules and regulations of the SEC relating to such Registration, and make generally available to its security holders earnings statements satisfying the provisions of Section 11(a) of the Securities Act, no later than forty-five (45) calendar days after the end of any twelve (12) month period (or ninety (90) calendar days, if such period is a fiscal year) commencing at the end of any fiscal quarter in which Registrable Securities are sold to underwriters in an Underwritten Offering, or, if not sold to underwriters in such an offering, beginning with the first month of the Company's first fiscal quarter commencing after the effective date of the Registration Statement, which statements shall cover said 12-month period.

6. Registration Expenses.

(a) Demand Registrations. The Company shall bear all Registration Expenses incurred in connection with any Demand Registration and of any Registration which does not become or is not maintained effective in accordance with the requirements specified in SECTION 5(a) other than any Registration terminated prior to effectiveness at the request of, or primarily as a result of, the actions of Holders whose Registrable Securities are included in such registration. Notwithstanding the foregoing, the Underwriters' Commissions incurred in connection with a Demand Registration that becomes effective shall be shared by the Holders of the Registrable Securities whose Registrable Securities are included in such Registration pro rata, in accordance with the aggregate amount of Registrable Securities sold by such Holders.

(b) Piggyback Registrations. The Company shall bear all Registration Expenses incurred in connection with any Piggyback Registrations. Notwithstanding the foregoing, the Underwriters' Commissions incurred in connection with a Piggyback Registration that becomes effective shall be shared by the Company and the Holders of the Registrable Securities whose Registrable Securities are

included in such Registration pro rata, in accordance with the aggregate amount of Registrable Securities sold by the Company and such Holders.

(c) Company Expenses. The Company also will, in any event, pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit, the fees and expenses incurred in connection with any listing of the securities to be registered on a securities exchange, and the fees and expenses of any Person, including special experts, retained by the Company.

7. Indemnification.

(a) Indemnification by Company. The Company agrees to indemnify and hold harmless each Indemnified Holder from and against all Claims arising out of or based upon any Misstatement or alleged Misstatement, except insofar as such Misstatement or alleged Misstatement was based upon information furnished in writing to the Company by such Indemnified Holder expressly for use in the document containing such Misstatement or alleged Misstatement. This indemnity shall not be exclusive and shall be in addition to any liability which the Company may otherwise have.

The foregoing notwithstanding, the Company shall not be liable to the extent that any such Claim arises out of or is based upon a Misstatement or alleged Misstatement made in any preliminary prospectus if (1) such Indemnified Holder failed to send or deliver a copy of the Prospectus with or prior to the delivery of written confirmation of the sale of Registrable Securities giving rise to such Claim and (2) the Prospectus would have corrected such untrue statement or omission.

In addition, the Company shall not be liable to the extent that any such Claim arises out of or is based upon a Misstatement or alleged Misstatement in a Prospectus, (x) if such Misstatement or alleged Misstatement is corrected in an amendment or supplement to such Prospectus and (y) having previously been furnished by or on behalf of the Company with copies of the Prospectus as so amended or supplemented, such Indemnified Holder thereafter fails to deliver such Prospectus as so amended or supplemented prior to or concurrently with the sale to the person who purchased a Registrable Security from such Indemnified Holder and who is asserting such Claim.

The Company shall also provide customary indemnifications to underwriters, selling brokers, dealer managers and similar securities industry professionals participating in a distribution covered by a Registration Statement, their officers and directors and each Person who controls such Persons (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act).

(b) Indemnification Procedures. If any action or proceeding (including any governmental investigation or inquiry) shall be brought or asserted against an Indemnified Holder in respect of which indemnity may be sought from the Company, such Indemnified Holder shall promptly notify the Company in writing, and the Company may assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Holder and the payment of all expenses.

Such Indemnified Holder shall have the right to employ separate counsel in any such action and to participate in the defense thereof, but the fees and expenses of such separate counsel shall be at the expense of such Indemnified Holder unless (1) the Company has agreed to pay such fees and expenses, (2) the Company shall have failed to assume the defense of such action or proceeding or has failed to employ counsel reasonably satisfactory to such Indemnified Holder in any such action or proceeding, or (3) the named parties to any such action or proceeding (including any impleaded parties) include both such Indemnified Holder and the Company, and such Indemnified Holder shall have been advised in writing by counsel that there may be one or more legal defenses available to such Indemnified Holder that are different from or additional to those available to the Company.

If such Indemnified Holder notifies the Company in writing that it elects to employ separate counsel at the expense of the Company as permitted by the provisions of the preceding paragraph, the

Company shall not have the right to assume the defense of such action or proceeding on behalf of such Indemnified Holder. The foregoing notwithstanding, the Company shall not be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any time for such Indemnified Holder and any other Indemnified Holders (which firm shall be designated in writing by such Indemnified Holders) in connection with any one such action or proceeding or separate but substantially similar or related actions or proceedings in the same jurisdiction arising out of the same general allegations or circumstances.

The Company shall not be liable for any settlement of any such action or proceeding effected without its written consent, but if settled with its written consent, or if there be a final judgment for the plaintiff in any such action or proceeding, subject to SECTION 7(a), the Company agrees to indemnify and hold harmless such Indemnified Holders from and against any loss or liability by reason of such settlement or judgment.

(c) Indemnification by Holder of Registrable Securities. Each Holder of Registrable Securities agrees to indemnify and hold harmless the Company, its directors and officers and each Person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Holder, but only with respect to information relating to such Holder furnished in writing by such Holder expressly for use in any Registration Statement, Prospectus or preliminary prospectus. In no event, however, shall the liability hereunder of any selling Holder of Registrable Securities be greater than the dollar amount of the proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation.

In case any action or proceeding shall be brought against the Company or its directors or officers or any such controlling person, in respect of which indemnity may be sought against a Holder of Registrable Securities, such Holder shall have the rights and duties given the Company and the Company or its directors or officers or such controlling person shall have the rights and duties given to each such Holder by SECTION 7(a) and SECTION 7(b), above. The Company shall be entitled to receive indemnities from underwriters, selling brokers, dealer managers and similar securities industry professionals participating in the distribution, to the same extent as provided above with respect to information so furnished in writing by such Persons specifically for inclusion in any Prospectus or Registration Statement.

(d) Contribution. If the indemnification provided for in this SECTION 7 is unavailable to an indemnified party under SECTION 7(a) or SECTION 7(c), above (other than by reason of exceptions provided in those Sections) in respect of any Claims referred to in such Sections, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Claims in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and of the Holder of Registrable Securities on the other in connection with the statements or omissions which resulted in such Claims as well as any other relevant equitable considerations. The amount paid or payable by a party as a result of the Claims referred to above shall be deemed to include, subject to the limitations set forth in SECTION 7(b), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

The relative fault of the Company on the one hand and of the Holder of Registrable Securities on the other shall be determined by reference to, among other things, whether the Misstatement or alleged Misstatement relates to information supplied by the Company or by the Holder of Registrable Securities and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such Misstatement or alleged Misstatement.

The Company and each Holder of Registrable Securities agree that it would not be just and equitable if contribution pursuant to this SECTION 7(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above.

Notwithstanding the provisions of this SECTION 7(d), an Indemnified Holder shall not be required to contribute any amount in excess of the amount by which (1) the total price at which the securities that were sold by such Indemnified Holder and distributed to the public were offered to the public exceeds (2) the amount of any damages which such Indemnified Holder has otherwise been required to pay by reason of such Misstatement. 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.

8. Requirements for Participation in Underwritten Offerings.

No Person may participate in any Underwritten Offering pursuant to a Registration hereunder unless such Person (a) agrees to sell such Person's securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements.

9. Suspension of Sales.

Upon receipt of written notice from the Company that (a) a Registration Statement or Prospectus contains a Misstatement or (b) in the reasonable determination of the Company, there exist circumstances not yet disclosed to the public which would be required to be disclosed in such Registration Statement and the disclosure of which would be materially harmful to the Company, each Holder of Registrable Securities shall forthwith discontinue disposition of Registrable Securities until such Holder has received copies of the supplemented or amended Prospectus required by SECTION 5(l) hereof, or until such Holder is advised in writing by the Company that the use of the Prospectus may be resumed, and, if so directed by the Company, such Holder shall deliver to the Company (at the Company's expense) all copies, other than permanent file copies then in such Holder's possession, of the Prospectus covering such Registrable Securities current at the time of receipt of such notice. The Company shall use all commercially reasonable efforts to minimize the length of such suspension of sales, provided, that the Company may require the suspension of sales for a period of ninety (90) calendar days in the event that the disclosure of any circumstances, in the reasonable determination of the Company, would be harmful in any material respect to the Company. In no event, however, shall the aggregate period of time that the Company postpones the filing or declaration of effectiveness of any Registration Statement pursuant to SECTION 5, above, or suspends sales of Registrable Securities pursuant to this SECTION 9 under any Registration Statement, taken together with all such other periods with respect to such Registrations Statement exceed, in the aggregate, ninety (90) calendar days.

10. Future Registration Rights Agreements.

Except for an underwriting agreement between the Company and one or more professional underwriters of securities, the Company shall not agree to register any Equity Securities under the Securities Act, other than Junior Securities registered on Forms S-8 or S-4, unless such agreement specifically provides that:

(a) the Holder of such Equity Securities may not participate in any Demand Registration without the consent of each of the Series C Stockholders and Series E Stockholders unless:

(1) the offering of the Registrable Securities is to be a Firm Commitment Underwritten Offering and the managing underwriter concludes that the public offering or sale of such Equity Securities would not interfere with the successful marketing of all Series C Registrable Securities and Series E Registrable Securities requested to be sold, and

(2) the Series C Stockholders of Series C Registrable Securities and the Series E Stockholders of Series E Registrable Securities shall have the right to participate, to the extent they may request, in any Registration Statement initiated under a Demand Registration right exercised by any of the Series C Stockholders of Series C Registrable Securities (if the Series C Stockholders of Series C Registrable Securities in the aggregate hold more than 50% of the Series C Registrable Securities then outstanding) or the Series E Stockholders of Series E Registrable Securities (if the Series E Stockholders of Series E Registrable Securities in the aggregate hold more than 50% of the Series E Registrable Securities then outstanding), except that if the managing underwriter of a public offering made pursuant to such a Demand Registration limits the number of shares of Common Stock to be sold, the participation of the Series C Stockholders of the Series C Registrable Securities, the Series E Stockholders of the Series E Registrable Securities and the Holders of all other shares of Common Stock (other than the Equity Securities held by such Holder of Equity Securities) shall be determined as set forth in SECTION 2 hereof,

(b) the Holder of such Equity Securities may not participate in any Piggyback Registration if the sale of Registrable Securities is to be underwritten unless, if the managing underwriter limits the total number of shares to be sold, the Holders of such Equity Securities, the Series C Stockholders of Series C Registrable Securities and the Series E Stockholders of Series E Registrable Securities are entitled to participate in such underwritten distribution based on the order of priority set forth in SECTION 3 hereof, and

(c) all Equity Securities excluded from any Registration as a result of the foregoing limitations may not be publicly offered or sold for a period (not to exceed at least thirty (30) calendar days prior to the effective date and sixty (60) calendar days thereafter) that the managing underwriter reasonably determines is necessary in order to effect the Underwritten Offering of Registrable Securities registered pursuant to this Agreement.

11. Assignment and Transfer of Registration Rights.

(a) Restrictions on Transfer; Transferee Obligations. No Stockholder may transfer, assign, sell or otherwise dispose of Registrable Securities unless such transfer is (i) made pursuant to an effective registrations statement under the Securities Act or (ii) is exempt from registration under the Securities Act and exempt from qualification under any applicable state and foreign securities laws.

Each person (other than the Company) to whom the Registrable Securities are transferred must, as a condition precedent to the validity of such transfer, acknowledge in writing to the Company that such person is bound by the provisions of this Agreement and that the transferred Registrable Securities are subject to the Hold-Back provisions of SECTION 4, each as specified therein, to the same extent such Registrable Securities would be so subject if retained by the Stockholder transferring such Registrable Securities.

(b) Assignment of Registration Rights. Subject to any restrictions on transfer under applicable law and pursuant to other agreements, the rights to cause the Company to register Registrable Securities pursuant to this SECTION 11 may be assigned (but only with all related obligations) by an Other Stockholder to a transferee or assignee of such securities who, after such assignment or transfer, holds at least Two Hundred Fifty Thousand (250,000) shares of Registrable Securities (as appropriately adjusted for stock splits, stock dividends, combinations and other recapitalizations subsequent to the date hereof); provided, that: (i) 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; (ii) such transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of this Agreement, including, without limitation, the provisions of SECTION 4; and (iii) 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 Securities Act. For 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 11.

12. Termination of Registration Rights.

No Other Stockholder shall be entitled to exercise any right provided for in this Agreement after two (2) years following the consummation of the sale of securities pursuant to a registration statement filed by the Company under the Securities Act in connection with the first firm commitment underwritten public offering of its Common Stock to the general public subsequent to March 2, 2001. In addition, the right of any Holder to request inclusion in any registration pursuant to SECTION 3 shall terminate on the closing of the first Company-initiated registered public offering of Common Stock of the Company subsequent to March 2, 2001 if all shares of Registrable Securities held or entitled to be held upon conversion of any securities by such Holder may immediately be sold under Rule 144 during any ninety (90) day period, or on such date after the closing of the first Company-initiated registered public offering of Common Stock of the Company subsequent to March 2, 2001 as all shares of Registrable Securities held or entitled to be held upon conversion by such Holder may immediately be sold under Rule 144 during any ninety (90) day period.

13. Specific Enforcement.

Each Stockholder and the Company expressly agree that the Stockholders will be irreparably damaged if this Agreement is not specifically enforced. Upon a breach or threatened breach of the terms, covenants and/or conditions of this Agreement by a Stockholder or the Company, the other Stockholders shall, in addition to all other remedies, be entitled to a temporary or permanent injunction, without showing any actual damage, and/or a decree for specific performance, in accordance with the provisions hereof.

14. Legend.

Each certificate evidencing shares of the Company's Common Stock and Preferred Stock that are subject to this Agreement shall bear a legend substantially as follows:

"The securities represented hereby have not been registered under the Securities Act of 1933, as amended, or any state securities law, and may not be offered, sold, transferred or otherwise disposed of unless registered under the Securities Act of 1933, as amended, and any applicable state securities laws, or an exemption from such registration is available. The securities represented hereby are subject to the terms and conditions of a certain Amended and Restated Registration Rights Agreement, dated as of June 28, 2001, a copy of which the Company will furnish to the holder of this certificate upon request and without charge."

15. Notices.

All notices, requests, consents and other communications provided for or permitted hereunder shall be made in writing and shall be delivered by hand-delivery, registered or certified first-class mail, return receipt requested, or sent by telecopier or telex, addressed as follows:

(a) if to GE, at its address set forth on the signature pages hereto, with a copy to Xxxxxx, Xxxx & Xxxxxxxx LLP, 000 Xxxxx Xxxxx Xxxxxx, Xxx Xxxxxxx, Xxxxxxxxxx 00000-0000, Facsimile: (000) 000-0000, Attention: Xxxxx X. Xxxxxx;

(b) if to a Stockholder of Registrable Securities who is not GE, at the most current address given by the Stockholder to the Company in accordance with the provisions hereof, which address initially is the address of the Stockholder set forth on the signature pates hereto; and

(c) if to the Company, initially at its address set forth on the signature pages hereto and thereafter at such other address, notice of which is given in accordance with the provisions hereof, with a copy to Skadden, Arps, Slate, Xxxxxxx & Xxxx LLP, 000 Xxxxx Xxxxx Xxxxxx, Xxxxx 0000, Xxx Xxxxxxx, Xxxxxxxxxx 00000, Facsimile: (000) 000-0000, Attn: Xxxxx Xxxx. All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five (5) business days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt acknowledged, if telecopied; and on the next business day, if timely delivered to an air courier guaranteeing overnight delivery. The Company shall promptly provide a list of the most current addresses of the Stockholders given to it in accordance with the provisions hereof to any such Stockholder for the purpose of enabling such Stockholder to communicate with other such Stockholders in connection with this Agreement.

16. Entire Agreement and Amendments.

(a) This Agreement, together with the Amended and Restated Co-Sale Agreement, dated as of even date herewith, constitutes the entire agreement of the parties with respect to the subject matter hereof and supersedes all prior agreements with respect to the subject matter hereof in their entirety. The parties hereto acknowledge and agree that each such prior agreement shall be of no force and effect with respect to the parties hereto following the execution of this Agreement.

(b) Neither this Agreement nor any provision hereof may be waived, modified, amended or terminated except by a written agreement signed by the Company and Stockholders owning at least eighty percent (80%) of the shares owned by the Stockholders; provided, however, that (i) any amendment hereto shall require the consent of the holders of 50% of the then outstanding shares of Preferred Registrable Securities; and provided further, that any amendment or modification of this Agreement that would adversely affect any of the expressed rights contained herein of any party hereto may be effected only with the consent of such party.

17. Governing Law; Successors and Assigns.

This Agreement shall be governed by the laws of the State of New York and shall bind and inure to the benefit of and be binding upon the respective heirs, personal representatives, executors, administrators, successors and assigns of the parties (including transferees of any shares of Registrable Securities). Without limiting the generality of the foregoing, all covenants and agreements of the Stockholders shall bind any and all subsequent holders of their shares, and the Company agrees that it shall not transfer on its records any such shares unless (i) the transferor Stockholder shall have first delivered to the Company and the other Stockholders the written agreement of the transferee to be bound by this Agreement to the same extent as if such transferee had originally been a Stockholder hereunder and (ii) the certificate or certificates evidencing the shares so transferred bear the legend specified in SECTION 14.

18. Expenses.

If any action at law or in equity is necessary to enforce or interpret the terms of this Agreement, the prevailing party shall be entitled to reasonable attorneys' fees, costs and necessary disbursements in addition to any other relief to which such party may be entitled.

19. Severability.

If any provision of this Agreement, or the application thereof, will for any reason and to any extent be invalid or unenforceable, the remainder of this Agreement and application of such provision to other persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of the void or unenforceable provision.

20. Aggregation of Stock.

All shares of Registrable Securities held or acquired by affiliated entities or any Stockholder shall be aggregated together for the purpose of determining the availability of any rights under this Agreement.

21. Further Assurances.

Each party agrees to cooperate fully with the other parties and to execute such further instruments, documents and agreements and to give such further written assurances as may be reasonably requested by any other party to evidence and reflect the transactions described herein and contemplated hereby and to carry into effect the intents and purposes of this Agreement.

22. Captions.

Captions are for convenience only and are not deemed to be part of this Agreement.

23. Counterparts.

This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

24. Other Agreements.

The Company shall not, on or after the date of this Agreement, enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof.

Other than as disclosed on SCHEDULE A attached hereto, the Company has not previously entered into any agreement with respect to its securities granting any "piggy back" registration rights to any Person. The Company represents and warrants to each of the Holders of Registrable Securities that, except as set forth in this Agreement or on SCHEDULE B attached hereto, as of the date hereof, there are no outstanding "demand" registration rights with respect to the Company's securities. Should the rights granted to the Holders of Registrable Securities hereunder in any way conflict with the rights granted to the holders of the Company's securities under any agreement listed on either SCHEDULE A or SCHEDULE B, the provisions of such scheduled agreement shall be controlling.

25. Forms.

All references in this Agreement to particular forms of Registration Statements are intended to include all successor forms which are intended to replace, or to apply to similar transactions as, the forms herein referenced.
