The Company acknowledges that the plan of distribution contemplated by such Registration Statement shall include offers and sales through underwriters or agents, offers and sales directly to investors, block trades and such other methods of offer and sale as the Investor Stockholders shall request. The Company will use its reasonable best efforts to cause the Registration Statement to be declared effective by the SEC within 90 days following the earlier of the date of (x) the conversion of the Notes or (y) the initial issuance of the Series B Preferred Stock, in each case, pursuant to the terms and conditions of the Purchase Agreement. The Company will cause such Registration Statement to remain effective until such time as all of the shares of Common Stock designated thereunder are sold or the holders thereof are entitled to rely on Rule 144(k) for sales of Registrable Securities without registration under the Securities Act and without compliance with the public information, sales volume, manner of sale or notice requirements of Rule 144(c), (e), (f) or (h).

If any registration pursuant to this Section 3 is an underwritten offering, the Pequot Stockholders together with one additional Investor Stockholder selected by the Pequot Stockholders will select, upon consultation with the Company, as the investment banker(s) and manager(s) that will administer the offering a nationally recognized investment banker(s) and manager(s) with demonstrable industry-specific expertise and experience and reasonably acceptable to the Company provided that for so long as General Electric Pension Trust (“GEPT”) shall be a holder of or entitled to Registrable Securities which are subject to an underwritten offering, in the case of any such public offering or equity of the Company in which existing shareholders of the Company are permitted to sell such equity, GEPT shall have the right, in its sole discretion, to approve or disapprove of any underwriter in which General Electric Company owns a direct or indirect interest of five percent (5%) or more.

Section 4. Piggyback Registrations.

(a) Right to Piggyback. Whenever the Company proposes to register any of its securities in an underwritten offering under the Securities Act, whether for its own account or for the account of another stockholder (except for the registration of securities to be offered pursuant to an employee benefit plan on Form S-8, pursuant to a registration made on Form S-4 or any successor forms then in effect) at any time other than pursuant to a registration in connection with Section 3 above and the registration form to be used may be used for the registration of the Registrable Securities (a “Piggyback Registration”), it will so notify in writing all holders of Registrable Securities no later than twenty (20) days prior to the anticipated filing date. Subject to the provisions of Section 4(c), the Company will include in the Piggyback Registration all Registrable Securities, on a pro rata basis based upon the total number of Registrable Securities with respect to which the Company has received written requests for inclusion within ten (10) days after the issuance of the Company’s notice. Such holder’s notice shall state the intended method of disposition of the Registrable Securities by such holder. Such Registrable Securities may be made subject to an underwriters’ over-allotment option, if so requested by the managing underwriter. The holders of Registrable Securities may withdraw all or any part of the Registrable Securities from a Piggyback Registration at any time before ten (10) business days prior to the effective date of the Piggyback Registration. In any Piggyback Registration, the Company, the holders of Registrable Securities and any Person who hereafter becomes entitled to register its securities in a registration initiated by the Company must sell their securities on the same terms and conditions. A registration of Registrable Securities pursuant to this Section 4 shall be in addition to the registration pursuant to Section 3.

(b) Piggyback Expenses. The Company shall pay to the holders of the Registrable Securities included in a Piggyback Registration all Registration Expenses of those holders.

(c) Underwriting; Priority on Piggyback Registrations. The right of any such holder to be included in an underwritten registration pursuant to this Section 4 shall be conditioned upon such holder’s participation in such underwriting and the inclusion of such holder’s Registrable Securities in the underwriting to the extent provided herein. All holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. If the managing underwriter gives the Company its written opinion that the total number or dollar amount of securities requested to be included in the registration exceeds the number or

5

dollar amount of securities that can be sold, the Company will include the securities in the registration in the following order of priority: (i) first, subject to the first proviso below, all securities the Company or the stockholder, if any, on whose account securities are being registered proposes to sell; (ii) second, subject to the first proviso below, up to the full number or dollar amount of Registrable Securities requested to be included in the registration (allocated pro rata among the holders of Registrable Securities requested to be included in the registration, on the basis of the dollar amount or number of Registrable Securities requested to be included, as the case may be); (iii) third, up to the full number or dollar amount of Pequot Registrable Securities requested to be included in the registration (allocated pursuant to the Pequot Registration Rights Agreement) and (iv) fourth, any other securities (provided they are of the same class as the securities sold by the Company) requested to be included, allocated among the holders of such securities in such proportions as the Company and those holders may agree; provided, that at least fifteen percent (15%) of the Registrable Securities and fifteen percent (15%) of the Pequot Registrable Securities requested to be included in such registration shall be included in the offering; provided, further, that, (i) the holders of Registrable Securities shall not be subject to any cutback in the amount of Registrable Securities requested to be included in the registration unless all other holders of securities requesting to be included in such registration other than the stockholder, if any, on whose account securities are being registered, and, other than the holders of the Pequot Registrable Securities to the extent of fifteen percent (15%) of the Pequot Registrable Securities, have been excluded from such registration and (ii) the holders of the Pequot Registrable Securities shall not be subject to any cutback in the amount of Pequot Registrable Securities requested to be included in the registration unless all other holders of securities requesting to be included in such registration, other than the holders of the Registrable Securities, have been excluded from such registration. In the event that the managing underwriter advises the Company that an underwriters’ over-allotment option is necessary or advisable, the allocation provided for in this Section 4(c) shall apply to the determination of which securities are to be included in the registration of such shares.

(d) Selection of Underwriters. In any Piggyback Registration, the Company will select as the investment banker(s) and manager(s) that will administer the offering a nationally recognized investment banker(s) and manager(s) with demonstrable industry-specific expertise and experience. The Company and the holders of Registrable Securities whose shares are being registered shall enter into a customary underwriting agreement with such investment banker(s) and manager(s); provided that for so long as GEPT shall be a holder of or entitled to Registerable Securities which are subject to an underwritten offering, in the case of any such public offering or equity of the Company in which existing shareholders of the Company are permitted to sell such equity, GEPT shall have the right, in its sole discretion, to approve or disapprove of any underwriter in which General Electric Company owns a direct or indirect interest of five percent (5%) or more.

(e) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 4 prior to the effectiveness of such registration whether or not any holder has elected to include securities in such registration. The Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with Section 7 hereof.

Section 5. “Lock-Up” Agreements.

If requested by the managing underwriter, each holder of Registrable Securities agrees not to sell, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale with respect to (each, a “Disposition”) any Registrable Securities (or other securities) of the Company held by such holder (other than those included in the registration) for a 30 day period (or such longer period requested by the managing underwriter which shall in no event exceed 90 days) after the effective date of the first two registrations by the Company only (and not by any stockholder on whose account securities are to be registered) pursuant to Section 4 after the date hereof unless the managing underwriter(s) agrees otherwise; provided, however, that all officers and directors of the Company, all holders of at least five percent (5%) of the Company’s equity securities purchased from the Company (other than securities purchased from the Company at any time after the date of this Agreement in a registered public offering) and all other persons with registration rights (whether or not pursuant to this Agreement) are bound by and have entered into a similar agreement and the restrictions on transfer have not been waived in whole or in part with respect to any such officers, directors, holders or persons. If any officer or director, holder or person is released by the Company from such similar agreements or the Company has waived in whole or in part any restrictions on transfer, the Investor Stockholders shall be similarly released by the Company or shall be entitled to require that the Company modify the obligations of such Investor Stockholders in connection with this Section 5.

(b) Other Expenses. To the extent the Company is not required to pay Registration Expenses, each holder of securities included in any registration will pay those Registration Expenses allocable to the holder’s securities so included, and any Registration Expenses not allocable will be borne by all sellers in proportion to the number of securities each registers.

Section 8. Indemnification.

(a) Indemnification by Company. In the event of any registration of Registrable Securities under the Securities Act pursuant to this Agreement, to the full extent permitted by law, the Company agrees to indemnify and hold harmless each holder of Registrable Securities, its officers, directors, trustees, partners, employees, advisors and agents, and each Person who controls the holder (within the meaning of the Securities Act and the Exchange Act) against any and all

10

losses, claims, damages, liabilities and expenses arising out of (i) any untrue or allegedly untrue statement of material fact contained in or incorporated by reference into any registration statement or any amendment thereof under which such Registrable Securities were registered under the Securities Act, any prospectus or preliminary prospectus contained therein or any amendment thereof or any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, except to the extent the untrue statement or omission resulted from information that the holder furnished in writing to the Company expressly for use therein, and (ii) any failure to comply with any law, rule or regulation applicable to such registration. Such indemnity shall remain in full force and effect, regardless of any investigation made by such indemnified party, and shall survive the transfer of such Registrable Securities by such holder. In connection with a firm or best efforts underwritten offering, to the extent customarily required by the managing underwriter, the Company will indemnify the underwriters, their officers and directors and each Person who controls the underwriters (within the meaning of the Securities Act and the Exchange Act), to the extent customary in such agreements.

(b) Indemnification by Holders of Securities. In connection with any registration statement, each participating holder of Registrable Securities will furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any registration statement or prospectus and each participating holder agrees, severally and not jointly, to indemnify and hold harmless, to the extent permitted by law, the Company, its directors, officers, trustees, partners, employees, advisors and agents, and each Person who controls the Company (within the meaning of the Securities Act and the Exchange Act) against any and all losses, claims, damages, liabilities and expenses arising out of any untrue or allegedly untrue statement of a material fact or any omission or alleged omission to state a material fact required to be stated in the registration statement or prospectus or any amendment thereof or supplement thereto necessary to make the statements therein not misleading, but only to the extent that the untrue statement or omission is contained in or omitted from any information or affidavit the holder furnished in writing to the Company expressly for use therein and only in an amount not exceeding the net proceeds received by the holder with respect to securities sold pursuant to such registration statement. Such indemnity shall remain in full force and effect, regardless of any investigation made by the Company, and shall survive the transfer of such Registrable Securities by such holder. In connection with a firm or best efforts underwritten offering, to the extent customarily required by the managing underwriter, each participating holder of Registrable Securities will indemnify the underwriters, their officers and directors and each Person who controls the underwriters (within the meaning of the Securities Act and the Exchange Act), to the same extent as it has indemnified the Company; provided, that the indemnity obligations of any holder contained in such agreement shall be limited to the amount of such holder’s net proceeds received from the sale of its Registrable Securities in such offering.

(c) Indemnification Proceedings. Any Person entitled to indemnification under this Agreement will (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in the indemnified party’s reasonable judgment a conflict of interest may exist between the indemnified and indemnifying parties with respect to the claim, permit the indemnifying party to assume the defense of the claim with counsel reasonably satisfactory to the indemnified party. If the indemnifying party does not assume the defense, the indemnifying party will not be liable for any settlement made without its consent (but that consent may not be unreasonably withheld). No indemnifying party will consent to entry of any judgment

11

or will enter into any settlement that does not include as an unconditional term thereof the claimant’s or plaintiff’s release of the indemnified party from all liability concerning the claim or litigation or which includes any non-monetary settlement. An indemnifying party who is not entitled to or elects not to assume the defense of a claim will not be under an obligation to pay the fees and expenses of more than one counsel for all parties indemnified by the indemnifying party with respect to the claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between the indemnified party and any other indemnified party with respect to the claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of no more than one additional counsel for the indemnified parties.

(d) Contribution. If the indemnification provided for in Section 8(a) or (b) is unavailable to an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party thereunder shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of the indemnified party and the indemnifying party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnified party and the indemnifying party and the parties’ relative intent and knowledge.

The parties hereto agree that it would not be just and equitable if contribution pursuant this Section 8(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding anything herein to the contrary, no participating holder of Registrable Securities acting as an indemnifying party shall be required to contribute any amount in excess of the amount by which the net proceeds of the offering (before deducting expenses, if any) received by such participating holder exceeds the amount of any damages that such participating holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

specific performance or injunctive relief, or both, in the event of a breach or a threatened breach of this Agreement.

(m) Validity of Provisions. Should any part of this Agreement for any reason be declared by any court of competent jurisdiction to be invalid, that decision shall not affect the validity of the remaining portion, which shall continue in full force and effect as if this Agreement had been executed with the invalid portion eliminated; provided, however, that this Agreement shall be interpreted to carry out to the greatest extent possible the intent of the parties and to provide to each party substantially the same benefits as such party would have received under this Agreement if such invalid part of this Agreement had been enforceable. Whenever the words “include” or “including” are used in the Agreement, they shall be deemed to be followed by the words “without limitation.”
