Subject to the availability of required financial information, within 45 days after the Company receives written notice of a request for a 415 Registration, the Company shall file with the SEC a registration statement under the Securities Act for the 415 Registration. The Company shall use its best efforts to cause the 415 Registration to be declared effective under the Securities Act as soon as practical after filing, and once effective, the Company shall (subject to the provisions of clause (ii) below) cause such 415 Registration to remain effective for such time period as is specified in such request, but for no time period longer than the period ending on the earlier of (1) the third anniversary of the date of filing of such 415 Registration, (2) the date on which all Registrable Securities so registered have been sold pursuant to the 415 Registration or -5- 6 (3) the date as of which there are no longer any Registrable Securities in existence.

(iii) If in connection with any Takedown the managing underwriters (selected in accordance with clause (iv) below) advise the Company that, in their opinion, the inclusion of any securities other than Cornerstone Registrable Securities, Kuck Registrable Securities, PPEI Registrable Securities, or Series C Registrable Securities would adversely affect the marketability of the offering, then no such other securities shall be permitted to be included. Additionally, if in connection with such an offering, the number of Cornerstone Registrable Securities, Kuck Registrable Securities, PPEI Registrable Securities, Series C Registrable Securities and other securities (if any) requested to be included in such Takedown exceeds the number of Cornerstone Registrable Securities, PPEI Registrable Securities, Kuck Registrable Securities, Series C Registrable Securities and other securities which can be sold in such offering without adversely affecting the marketability of the offering, the Company shall include in such Takedown (i) first, the Cornerstone Registrable Securities, Kuck Registrable Securities, PPEI Registrable Securities and Series C Registrable Securities requested to be included in such Takedown, pro rata among the holders of such Cornerstone Registrable Securities, Kuck Registrable Securities, PPEI Registrable Securities and Series C Registrable Securities on the basis of the number of Cornerstone Registrable Securities, Kuck Registrable Securities, PPEI Registrable Securities and Series C Registrable Securities owned by each such holder, (ii) second, the remaining Registrable Securities requested to be included in such Takedown, pro rata among the holders of such Registrable Securities on the basis of the number of Registrable Securities owned by each such holder, and (iii) third, other securities requested to be included in such Takedown to the extent permitted hereunder. (iv) The holders of a majority of the Cornerstone Registrable Securities and the holders of a majority of the PPEI Registrable Securities shall have the right to retain and select an investment banker and manager to administer the 415 Registration with respect to Registrable Securities and any Takedown pursuant thereto. (v) In addition to the provisions in Section 6 below, all expenses incurred in connection with the management of the 415 Registration (whether incurred by the Company, the holders of the Cornerstone Registrable Securities, or the holders of the PPEI Registrable Securities) -6- 7 shall be borne by the Company (including, without limitation, all fees and expenses of the investment banker and manager) (excluding discounts and commissions). (h) Other Registration Rights. Except as provided in this Agreement, the Company shall not grant to any Persons the right to request the Company to register any of its equity securities or any securities convertible or exchangeable into or exercisable for such securities, without the prior written consent of the holders of a majority of the Cornerstone Registrable Securities and the holders of a majority of the PPEI Registrable Securities. 3.

If a Piggyback Registration is an underwritten secondary registration on behalf of holders of the Company's securities (which registration was consented to pursuant to Section 2(h) above), and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without adversely affecting the marketability of the offering, the Company will include in such registration (i) first, the securities requested to be included therein by the holders requesting such registration, (ii) second, the number of Registrable Securities requested to be included in such registration, pro rata among the holders of such Registrable Securities on the basis of the number of shares of Registrable Securities owned by each such holder, and (iii) third, other securities, if any, requested to be included in such registration not covered by clause (i) above.

In connection with an underwritten offering, the Company will indemnify such underwriters, their officers and directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the holders of Registrable Securities. (b) In connection with any registration statement in which a holder of Registrable Securities is participating, each such holder will furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, will indemnify the Company in connection with any registration of Registrable Securities, and its members, directors and officers and each Person who controls the Company (within the meaning of the Securities Act), as applicable, against any losses, claims, damages, liabilities and expenses resulting from any untrue or alleged untrue statement of material fact contained in such registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such holder; provided, that the obligation to indemnify will be individual to each holder and will be limited to the net amount of proceeds received by such holder from the sale of Registrable Securities pursuant to such registration statement.

If such defense is assumed, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one -12- 13 counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. (d) The indemnification provided for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any partner, member, officer, director or controlling Person of such indemnified party and will survive the transfer of securities. The Company, to the extent so liable, also agrees to make such provisions, as are reasonably requested by any indemnified party, for contribution to such party in the event that the Company's indemnification is unavailable for any reason. 8. Participation in Underwritten Registrations. No Person may participate in any registration hereunder which is underwritten unless such Person (a) agrees to sell such Person's securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements and (b) completes and executes all customary questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements; provided, that no holder of Registrable Securities included in any underwritten registration shall be required to make any representations or warranties to the Company or the underwriters other than representations and warranties regarding such holder and such holder's intended method of distribution. 9.
