(A) FILING OF SHELF REGISTRATION STATEMENT. The Company shall file within sixty (60) days after all Series A Preferred Units shall be exchanged for Preferred Stock, a "shelf" Registration Statement providing for the sale of all of the Registrable Securities of the Holder. The Company shall use its best efforts to cause such shelf Registration Statement to be declared effective by the SEC within one hundred and twenty (120) days thereafter. The Company agrees to use its best efforts to keep the shelf Registration Statement continuously effective until the earliest of (A) 24 months following the effective date of the Registration Statement, (B) such time as all of the Registrable Securities have been sold pursuant to the Registration Statement or Rule 144, and (C) the date on which the Registrable Securities may be sold without holding periods or volume restrictions in accordance with Rule 144. Any offering pursuant to a shelf registration provided for in this SECTION 2(A) may, at the election of the Holders of a majority of the Registrable Securities, be an Underwritten Offering. (B) DEMAND REGISTRATION. (i) At any time during which a shelf Registration Statement is not effective with respect to the Registrable Securities, upon receipt of a written request (a "REGISTRATION REQUEST"), which shall include a description of such Holders' proposed method of distribution (which method may, at the election of the Holders of a majority of the Registrable Securities, also include an Underwritten Offering by a nationally recognized Underwriter selected by the Company and reasonably acceptable to the Registering Holders) from Holders holding Registrable Securities having an aggregate expected offering price of at least $25,000,000 (or, all remaining Registrable Securities if all such remaining Registrable Securities shall have an aggregate expected offering price of less than $25,000,000), the Company shall (i) promptly give notice of the Registration Request to all non-requesting Holders and (ii) prepare and file with the SEC, within sixty (60) days after receipt of such Registration Request, a Registration Statement for the sale of all Registrable Securities held by the requesting Holders and any other Holder who makes a written request of the Company to have her or his Registrable Securities included in such Registration Statement, which such written request must be received by the Company within ten (10) days after such Holder receives the Registration Request (all of such Holders, collectively, the "REGISTERING HOLDERS"). Upon receipt of such written request, the Company shall use its best efforts to cause such Registration Statement to be -5- 6 declared effective within one hundred twenty (120) days after receipt of a Registration Request. The Company shall keep such Registration Statement continuously effective until the earlier of either: (i) the date on which all Registrable Securities have been sold pursuant to such Registration Statement or Rule 144 or (ii) two (2) years from the effective date of the Registration Statement. (ii) The Company shall not be required to effect more than three registrations pursuant to this SECTION 2(B). (iii) If any of the Registrable Securities registered pursuant to a Registration Statement filed under this SECTION 2(B) are to be sold in an Underwritten Offering, and the lead managing Underwriter advises the Registering Holders in writing that in its opinion the total number or dollar amount of Registrable Securities proposed to be sold in such offering is such as to materially and adversely affect the success of such offering, then the Company will include in such registration, first, the Registrable Securities of the Registering Holders and, second, any securities to be sold for the account of the Company and for the account of other security holders of the Company who have contractual rights to participate in such registration (the "OTHER HOLDERS") electing to include (but not being entitled to demand inclusion of) securities in such registration (it being understood that such lead managing Underwriter shall have the right to eliminate entirely the participation in such registration of the Company and such Other Holders). (iv) The Company shall be entitled to postpone, for a reasonable period of time not in excess of ninety (90) days, the filing of a Registration Statement of the Company, if it determines, in the good faith exercise of its reasonable business judgement, that such registration and offering could materially adversely affect the bona fide financing plans of the Company or would require the disclosure of information, the premature disclosure of which could materially adversely affect the Company or any transaction under consideration by the Company; provided, however, that the Company shall not be entitled to such postponement more than once in any 360-day period. (C) PIGGYBACK REGISTRATION RIGHTS. (i) If the Company proposes to file a Registration Statement under the Securities Act with respect to an offering by the Company for its own account (a "PRIMARY REGISTRATION") or for the account of any of its respective security holders (other than a registration statement on Form S-4 or S-8 (or any substitute form that may be adopted by the SEC) or filed in connection with an exchange offer or offering of securities solely to the Company's existing security holders)(a "SECONDARY REGISTRATION") and a Registration Statement is not otherwise effective with respect to the Preferred Stock issuable upon exchange of the Series A Preferred Units, then the Company shall promptly give written notice of such proposed filing to the Holders of Registrable Securities and such notice shall offer such Holders the opportunity to register -6- 7 such number of shares of Registrable Securities as each such Holder may request (a "PIGGYBACK REGISTRATION"). The Company shall use its all commercially reasonable efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable Securities requested to be included in a Piggyback Registration to be included on the same terms and conditions as any similar securities of the Company included therein. (ii) Any Holder requesting inclusion of Registrable Securities pursuant to this SECTION 2(C) may, prior to the effective date of the Registration Statement relating to such registration, revoke such request by delivering written notice of such revocation to the Company and the managing Underwriter, if any, at least two (2) business days prior to the effective date of the registration; provided, however, that if the Company, in consultation with its financial and legal advisors, determines that such revocation would materially delay the registration or otherwise require a recirculation of the Prospectus contained in the Registration Statement, then such Holder shall have no such right to revoke its request. If the withdrawal of any Registrable Securities would allow, within the marketing limitations set forth above, the inclusion in the underwriting of a greater number of shares of Registrable Securities, then, to the extent practicable and without delaying the underwriting, the Company shall offer to the Holders an opportunity to include additional shares of Registrable Securities, which additional Registrable Securities shall be included in such registration pro rata among the holders of Registrable Securities requesting such registration and the holders of such other securities on the basis of the number of securities requested for inclusion in such registration by each such holder. Any Registrable Securities excluded or withdrawn from such underwriting shall also be withdrawn from registration and shall not be transferred in a public distribution prior to ninety (90) days after the effective date of the Registration Statement relating thereto, or such shorter period of time as the managing Underwriter may require. (iii) The Company shall have the right to terminate or withdraw any registration initiated by it under this SECTION 2(C) prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. (D) REDUCTION IN AMOUNT OF SECURITIES. Notwithstanding anything contained herein, if the managing Underwriter or Underwriters of an offering described in this SECTION 2 are of the opinion that (i) the size of the offering that the Holders, the Company and/or such other Persons intend to make, or (ii) the kind of the securities that the Holders, the Company and/or any other persons or entities intend to include in such offering are such that the success of the offering would be materially and adversely affected by inclusion of the Registrable Securities requested to be included, then (A) if the size of the offering is the basis of such Underwriter's opinion, the amount of securities to be offered for the accounts of Holders shall be reduced pro-rata (on the basis of the Registrable Securities proposed for registration) to the extent necessary to reduce the total amount of securities to be included in such offering to the amount -7- 8 recommended by such managing Underwriter or Underwriters; provided that if securities are being offered for the account of other Persons as well as the Company, then (1) in the case of a Primary Registration, the reduction in the amount of securities requested to be offered shall be made first pro-rata among securities offered for the accounts of Holders and such other Persons, and (2) in the case of a Secondary Registration, the reduction in the amount of such securities requested to be offered shall be made in accordance with the terms of the registration rights agreement pursuant to which such Secondary Registration is made, provided that if any such registration rights agreement is silent with respect to reductions in shares being registered thereunder, then with respect to the Registrable Securities intended to be offered by Holders, the proportion by which the amount of such class of securities intended to be offered by Holders is reduced shall not exceed the proportion by which the amount of such class of securities intended to be offered by such other Persons is reduced, and (B) if the combination of securities to be offered is the basis of such Underwriter's opinion, (x) the Registrable Securities to be included in such offering shall be reduced as described in clause (A) above, or (y) if the actions described in clause (x) would, in the judgment of the managing Underwriter, be insufficient to substantially eliminate the adverse effect that inclusion of the Registrable Securities requested to be included would have on such offering, such Registrable Securities will be excluded from such offering. (E) EXPENSES. The Company shall pay all Registration Expenses in connection with any registration undertaken pursuant to SECTIONS 2(A), 2(B) and 2(C) hereof. The Holder shall pay all underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of such Holder's Registrable Securities pursuant to the Registration Statement. 3. HOLD-BACK AGREEMENT. Each Holder of Registrable Securities shall not effect any public sale or distribution of securities of the Company of the same or similar class or classes of the securities included in the Registration Statement or any securities convertible into or exchangeable or exercisable for such securities, including a sale pursuant to Rule 144 or Rule 144A under the Securities Act, during such periods as reasonably requested by the Underwriter in an underwritten public offering by the Company; provided that no Holder shall be so obligated under this SECTION 3 in the event that any such period requested by the Underwriter is longer than one hundred (100) days or occurs more than once in any twelve (12) month period. 4.

BLACK-OUT PERIOD. (A) Notwithstanding anything in SECTION 2(B)(IV) above to the contrary, if (1) the Company determines in its good faith judgment that the filing of a Registration Statement under SECTION 2 hereof or the use of any related Prospectus would require the disclosure of non-public material information that the Company has a bona fide business purpose for preserving as confidential or the disclosure of which would impede the Company's ability to consummate a material transaction, and that the Company is not otherwise required by applicable securities laws or regulations to disclose, or (2) all reports required to be filed by the Company pursuant to -12- 13 the Exchange Act have not been filed by the required date without regard to any extension, or if the consummation of any business combination by the Company has occurred or is probable for purposes of Rule 3-05 or Article 11 of Regulation S-X under the Act; then in either event and upon written notice of such by the Company, the rights of the Holders to offer, sell or distribute any Registrable Securities pursuant to the Registration Statement (shelf or otherwise, as appropriate) or to require the Company to take action with respect to the registration or sale of any Registrable Securities pursuant to the Registration Statement (shelf or otherwise, as appropriate) shall be suspended until the earlier of (i) the date upon which the Company notifies the Holders in writing that suspension of such rights for the grounds set forth in this Section 5 is no longer necessary, and (ii) one hundred twenty (120) days. The Company shall give such notice as promptly as practicable following the date that such suspension of rights is no longer necessary and the period of time for which the Company shall be obligated to keep the Registration Statement effective under SECTION 2 shall be extended by one day for each day of such suspension period. (B) In the case of an event which causes the Company to suspend the effectiveness of a Registration Statement (a "SUSPENSION EVENT"), the Company may give notice (a "SUSPENSION NOTICE") to the Holder to suspend sales of the Registrable Shares so that the Company may correct or update the Registration Statement (or such filings); provided, however, that such suspension shall continue only for so long as the Suspension Event or its effect is continuing. The Holder agrees that it will not effect any sales of the Registrable Shares pursuant to such Registration Statement (or such filings) at any time after it has received a Suspension Notice from the Company. If so directed by the Company, Holder will deliver to the Company all copies of the Prospectus covering the Registrable Shares held by them at the time of receipt of the Suspension Notice. The Holder may recommence effecting sales of the Registrable Shares pursuant to the Registration Statement (or such filings) following further notice to such effect (an "END OF SUSPENSION NOTICE") from the Company, which End of Suspension Notice shall be given by the Company promptly following the conclusion of any Suspension Event and the effectiveness of any required amendment or supplement to the Registration Statement. (C) Notwithstanding the provisions of SECTIONS 5(A) and 5(B) to the contrary no Suspension Notice may be given more than once in any twelve (12) month period. Moreover, notwithstanding SECTIONS 2(A), 2(B) and 2(C) hereof, if the Company shall give a Suspension Notice pursuant to this SECTION 5, the Company agrees that it shall extend the period during which the Registration Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from the date of the giving of the Suspension Notice to and including the date when the Holders shall have received the End of Suspension Notice and copies of the supplemented or amended Prospectus necessary to resume sales. 6. RULE 144 AND RULE 144A. For so long as the Company is subject to the reporting requirements of Section 13 or 15 of the Exchange Act, the Company covenants that it will timely file the reports required to be -13- 14 filed by it under the Securities Act and Section 13(a) or 15(d) of the Exchange Act and the rules and regulations adopted by the SEC thereunder and, if at any time the Company is not required to file such reports, it will, upon the request of any Holder of Registrable Securities, make publicly available other information so long as necessary to permit sales pursuant to Rule 144 under the Securities Act. The Company also covenants that it will provide the information required pursuant to Rule 144A(d)(4) under the Securities Act upon the request of any Holder of Registrable Securities and it will take such further action as any Holder of Registrable Securities may reasonably request, all to the extent required from time to time, to enable such Holder to sell its Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (a) Rule 144 under the Securities Act, as such Rule may be amended from time to time, (b) Rules 144A under the Securities Act, as such Rule may be amended from time to time, or (c) any similar rule or regulation hereafter adopted by the SEC. Upon the request of any Holder of Registrable Securities, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements. 7. INDEMNIFICATION. (A) The Company will indemnify each Holder, each such Holder's officers and directors, and each person controlling such Holder within the meaning of Section 15 of the Securities Act, against all claims, losses, damages, liabilities and expenses (including reasonable legal expenses), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement or prospectus relating to such Holders' Registrable Securities, or any amendment or supplement thereto, or based on 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; provided, however, that the Company will not indemnify and will not be liable to any Holder in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in conformity with and in reliance upon information furnished in writing to the Company by such Holder or by an Underwriter for inclusion therein. (B) Each Holder will indemnify the Company, each of its officers and directors, each underwriter, if any, of the Company's securities covered by such Registration Statement, and each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, against all claims, losses, damages, liabilities and expenses (including reasonable legal fees and expenses) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such Registration Statement or prospectus, or any amendment or supplement thereto, or based on 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 each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such Registration Statement or prospectus, in reliance upon and in conformity with information furnished in writing to the Company by such Holder for inclusion therein. -14- 15 (C) Each party entitled to indemnification under this SECTION 7 (the "INDEMNIFIED PARTY") shall give notice to the party required to provide indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought. However, the failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which it may have to the Indemnified Party pursuant to the provisions of this SECTION 7, except to the extent of the actual damages suffered by such delay in notification. The Indemnifying Party shall assume the defense of such action. including the employment of counsel, which shall be chosen by the Indemnifying Party and shall be reasonably satisfactory to the Indemnified Party, and payment of expenses in connection with such defense. The Indemnified Party shall have the right to employ its own counsel in any such case, but the legal fees and expenses of such counsel shall be at the expense of the Indemnified Party unless (i) the employment of such counsel shall have been authorized in writing by the Indemnifying Party, (ii) the Indemnifying Party shall not have assumed the defense of such action within a reasonable period of time, or (iii) the Indemnified Party shall have been reasonably advised by its counsel that there may be defenses available to it or them which are different from or additional to those available to Indemnifying Party (in which case the Indemnifying Party shall not have the right to direct the defense of such action on behalf of the Indemnified Party), in any of which events such fees and expenses shall be borne by the Indemnifying Party. No Indemnifying Party in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to each such Indemnified Party of a release from all liability in respect to such claim or litigation. (D) If the indemnification provided for in this SECTION 7 is unavailable to a party that would have been an Indemnified Party under this SECTION 7, then each party that would have been an Indemnifying Party hereunder shall, in lieu of indemnifying such Indemnified Party, contribute to the amount paid or payable by such Indemnified Party as a result of such claims, losses, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and such Indemnified Party on the other in connection with the statement or omission which resulted in such claims, losses, damages, liabilities and expenses, as well as any other relevant equitable considerations. The relative fault 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 related to information supplied by the Indemnifying Party or the Indemnified Party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and each Holder agree that it would not be just and equitable if contribution pursuant to this SECTION 7 were determined by pro rata allocation or by any other method of allocation that fails to take account of the equitable considerations referred to above in this SECTION 7(D). For purposes of this SECTION 7(D), each person, if any, who controls the Holder within the meaning of Section 15 of the Securities Act shall have the same rights to contribution as the Holder and each trust manager of the Company, each officer of the Company who signed the Registration Statement and each person, if any, who controls the Company -15- 16 within the meaning of Section 15 of the Securities Act shall have the same rights to contribution as the Company. (E) 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. (F) In no event shall any Holder be liable for any claims, losses, damages, liabilities or expenses pursuant to this SECTION 7 in excess of the net proceeds to such Holder for the sale of such Holder's Registrable Securities pursuant to a registration. 8.
