Notwithstanding anything to the contrary set forth herein, the Company shall be obligated to effect any one or more of such Required Registrations pursuant to a Shelf Registration Statement if the Majority Holders so request in connection with any Demand Request.

(c) Selection of Underwriters. In the event that the Registrable Securities to be registered pursuant to a Required Registration are to be disposed of in an underwritten public offering, the underwriters of such public offering shall be one or more underwriting firms of nationally recognized standing selected by the Majority Holders and shall be reasonably acceptable to the Company. In the event the Company elects to file a Demand Registration Statement on Form S-3 and the underwriters, if any, in such public offering or the Majority Holders request that the Company provide disclosures otherwise required in connection with a Form S-1 registration statement, then the Company shall include in such Demand Registration Statement such “long form” disclosures.

(d) Priority on Required Registrations. In the event that, in the case of any Required Registration, the managing underwriter for the public offering contemplated by Section 3.1(b) shall advise the Company in writing (with a copy to each holder of Registrable Securities

requesting sale) that, in such underwriter’s opinion, the amount of securities requested to be included in such Required Registration would adversely affect the public offering and sale (including pricing) of such Registrable Securities (such writing to state the basis of such opinion and the approximate number of Registrable Securities that may be included in such public offering without such effect), the Company will include in such Required Registration the number of Registrable Securities that the Company is so advised can be sold in such public offering, in the following amounts:

(i) first, all Registrable Securities requested to be sold by holders of Registrable Securities pursuant to Section 3.1(b) pro rata among such holders on the basis of the number of Registrable Securities owned by each such holders; and

(ii) second, securities proposed to be sold by the Company for its own account.

(e) Black Out Period. Notwithstanding any other provision of this Agreement to the contrary, if the Board reasonably determines that the registration and distribution of Registrable Securities (i) would reasonably be expected to impede, delay or interfere with, or require premature disclosure of, any material financing, offering, acquisition, merger, corporate reorganization, segment reclassification or discontinuation of operations, or other significant transaction or any negotiations, discussions or pending proposals with respect thereto, involving the Company or any of its Subsidiaries, or (ii) would require disclosure of non-public material information, the disclosure of which would reasonably be expected to adversely affect the Company, the Company shall (x) be entitled to postpone the filing or effectiveness or suspend the effectiveness of a registration statement and/or the use of any prospectus for a period of time not to exceed sixty (60) days and (y) promptly give the Stockholders written notice of such postponement or suspension (which notice need not specify the nature of the event giving rise to such suspension); provided, that the Company shall not utilize the right described in Section 3.1(b) more than once in any six (6) month period and provided further that the Company may extend such period to be up to ninety (90) days in the aggregate, but if it elects to do so it shall not be permitted to impose a subsequent black out period until a time that is more than six (6) months after the end of such extended black out period. Notwithstanding anything to the contrary set forth herein, any application of the provisions of Section 2.2(c) of this Agreement that results in a postponement of the effectiveness of a registration statement pursuant to this Section 3.1(e) shall not be included in calculating the 60-day period or 90-day period above.

Section 3.2 Incidental Registration.

(a) Filing of Registration Statement. If, at any time after the first (1st) anniversary of the date hereof the Company proposes to register, for its own account or for the account of any other Person any of its securities (an “Incidental Registration”) under the Securities Act (other than pursuant to a registration statement on Form S 4 or Form S 8 or any successor forms thereto) for sale to the public, it will at each such time give prompt written notice to all Stockholders of its intention to do so, which notice shall be given at least thirty (30) days prior to the date that a registration statement relating to such registration is proposed to be filed with the SEC. Upon the written request of any Stockholder to include Registrable Securities held by it that are not otherwise covered by the Shelf Registration Statement or a

Demand Registration Statement in such Incidental Registration statement (which request shall (i) be made within fifteen (15) days after the receipt of any such notice, and (ii) specify the Registrable Securities intended to be included by such holder), the Company will use all commercially reasonable efforts to effect the registration of all Registrable Securities that the Company has been so requested to register by such Stockholder; provided, however, that if, at any time after giving written notice of its intention to register any securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason to terminate such registration statement and not to register such securities, the Company may, at its election, give written notice of such determination to each such holder and, thereupon, shall be relieved of its obligation to register any Registrable Securities of such Persons in connection with such registration.

(b) Selection and Use of Underwriters. Underwriters, if any, in connection with any offering pursuant to this Section 3.2 shall be selected at the sole and exclusive discretion of the Company. No Stockholder shall Transfer any Registrable Securities included in the Incidental Registration other than through the underwriter or underwriters so selected by the Company.

(c) Priority on Incidental Registrations. If the managing underwriter for the offering contemplated by this Section 3.2 shall advise the Company in writing that, in such underwriter’s opinion, the number of securities requested to be included in such Incidental Registration would adversely affect the offering and sale (including pricing) of such securities, the Company shall include in such Incidental Registration the number of securities that the Company is so advised can be sold in such offering, in the following amounts and order of priority:

(i) first, securities proposed to be sold by the Company for its own account or for the account of any other Person not a party hereto; and

Section 3.5 Indemnification; Contribution.

(a) The Company shall indemnify, to the fullest extent permitted by applicable Law, each holder of Registrable Securities, its officers, directors, partners, employees and agents, if any, and each Person, if any, who controls such holder within the meaning of Section 15 of the Securities Act, against all losses, claims, damages, liabilities (or proceedings in respect thereof) and expenses (under the Securities Act or common law or otherwise), joint or several, resulting from any violation by the Company of the provisions of the Securities Act or any untrue statement or alleged untrue statement of a material fact contained in any registration statement or prospectus (and as amended or supplemented if amended or supplemented) or any preliminary prospectus or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, in light of the circumstances under which they were made) not misleading, except to the extent that such losses, claims, damages, liabilities (or proceedings in respect thereof) or expenses are caused by any untrue statement or alleged untrue statement contained in or by any omission or alleged omission from information concerning any holder of Registrable Securities furnished in writing to the Company by such holder expressly for use therein. No action or failure to act on the part of the underwriters (whether or not such underwriter is an Affiliate of any holder of Registrable Securities) shall affect the obligations of the Company to indemnify any holder of Registrable Securities or any other Person pursuant to the preceding sentence. In connection with any underwritten offering pursuant to Section 3.2, the Company agrees to enter into an underwriting agreement in customary form with the applicable underwriters, and the Company agrees to indemnify such underwriters, their officers, directors, employees and agents, if any, and each Person, if any, who controls such underwriters within the meaning of Section 15 of the Securities Act to the same extent as herein before provided with respect to the indemnification of the holders of Registrable Securities; provided that the Company shall not be required to indemnify any such underwriter, or any officer, director or employee of such underwriter or any Person who controls such underwriter within the meaning of Section 15 of the Securities Act, to the extent that the loss, claim, damage, liability (or proceedings in respect thereof) or expense for which indemnification is claimed results from such underwriter’s failure to send or give a copy of an amended or supplemented final prospectus to the Person asserting an untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of Registrable Securities to such Person if such statement or omission was corrected in such amended or supplemented final prospectus prior to such written confirmation and the underwriter was provided with such amended or supplemented final prospectus.

(b) In connection with any registration statement in connection with an offering in which a holder of Registrable Securities is participating, each such holder, severally and not jointly, shall indemnify, to the fullest extent permitted by applicable Law, the Company, each underwriter and their respective officers, directors, employees and agents, if any, and each Person, if any, who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages, liabilities (or proceedings in respect thereof) and expenses resulting from any untrue statement or alleged untrue statement of a material fact, or any omission or alleged omission of a material fact required to be stated in the registration statement or prospectus or preliminary prospectus or any amendment thereof or supplement thereto or necessary to make the statements therein (in the case of any prospectus, in light of the circumstances under which they were made) not misleading, but only to the extent that such untrue statement is contained in or such omission is from information so concerning a holder furnished in writing by such holder expressly for use therein; provided that such holder’s obligations hereunder shall be limited to an amount equal to the net proceeds to such holder of the Registrable Securities sold pursuant to such registration statement.

(c) Any Person entitled to indemnification under the provisions of this Section 3.5 shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim, with counsel reasonably satisfactory to the indemnified party; and if such defense is so assumed, such indemnifying party shall not enter into any settlement without the consent of the indemnified party if such settlement attributes liability to the indemnified party and such indemnifying party shall not be subject to any liability for any settlement made without its consent (which shall not be unreasonably withheld); and any underwriting agreement entered into with respect to any registration statement provided for under this Article III shall so provide. In the event an indemnifying party shall elect not to assume the defense of a claim, such indemnifying party shall not be obligated to pay the fees and expenses of more than one counsel or firm of counsel for all parties indemnified by such indemnifying party in respect of such claim.

(d) If for any reason the foregoing indemnity is unavailable, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other or (ii) if the allocation provided by clause (i) above is not permitted by applicable Law or provides a lesser sum to the indemnified party than the amount hereinafter calculated, in such proportion as is appropriate to reflect not only the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other but also the relative fault of the indemnifying party and the indemnified party as well as any other relevant equitable considerations. Notwithstanding the foregoing, no holder of Registrable Securities shall be required to contribute any amount in excess of the amount such holder would have been required to pay to an indemnified party if the indemnity under Section 3.5(b) were available. 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. The obligation of any Person to contribute pursuant to this Section 3.5 shall be several and not joint.

(e) An indemnifying party shall make payments of all amounts required to be made pursuant to the foregoing provisions of this Section 3.5 to or for the account of the indemnified party from time to time promptly upon receipt of bills or invoices relating thereto or when otherwise due or payable.

(f) The indemnity and contribution agreements contained in this Section 3.5 shall remain in full force and effect regardless of any investigation made by or on behalf of a participating holder of Registrable Securities, its officers, directors, agents or any Person, if any, who controls such holder as aforesaid, and shall survive the Transfer of Equity Securities by such holder and the termination of this Agreement for any reason.

Section 3.6 Holdback Agreements.

Each Stockholder agrees not to sell, make any short sale of, grant any option for the purchase of, or otherwise dispose of any securities, other than those Registrable Securities included in such Registration pursuant to Section 3.1 or 3.2(a) for the seven (7) days prior to and the ninety (90) days after the effectiveness of the registration statement pursuant to which such offering shall be made (or such longer periods as may be advised by the underwriter with respect to the applicable offering but in any event not to exceed thirty (30) days prior to and ninety (90) days after the effectiveness of such registration statement). The Company agrees that it and its executive officers will be subject to the holdback period requested by the underwriters of a Required Registration, if any, pursuant to this Section 3.6 to the extent that such underwriters determine such holdback by the Company and its executive officers is reasonably necessary for the successful offering and sale of all Registrable Securities in connection with such registration.

Section 3.7 Availability of Information.

The Company shall cooperate with each Stockholder who is a holder of any Registrable Securities in supplying such information as may be reasonably necessary for such holder to complete and file any information reporting forms presently or hereafter required by the SEC as a condition to the availability of an exemption from the Securities Act for the sale of any Registrable Securities.

Section 3.8 Information Concerning Stockholders.

It shall be a condition precedent to the obligations of the Company to include the Registrable Securities of any selling Stockholder in any registration statement or prospectus, as the case may be, that such selling Stockholder shall take the actions described in this Section 3.8:

(b) each selling Stockholder shall promptly (i) following it becoming aware thereof, notify the Company of the occurrence of any event that makes any statement made in a registration statement or prospectus regarding such selling Stockholder untrue in any material respect or that requires the making of any changes in a registration statement or prospectus so that, in such regard, it shall not contain any untrue statement of a material fact or omit any material fact required to be stated therein or necessary to make the statements (in the case of a prospectus, in light of the circumstances under which they were made), not misleading and (ii) in connection with providing such notice, provide the Company with such information in its possession as may be required to enable the Company to prepare a supplement or post-effective amendment to any such registration statement or a supplement to such prospectus;

(c) with respect to any registration statement for an underwritten offering, the inclusion of a Stockholder’s Registrable Securities therein shall be conditioned, at the managing underwriter’s request, upon the execution and delivery by such Stockholder of an underwriting agreement as may be negotiated by the Company;

(d) any sale of any Registrable Securities by any Stockholder shall constitute a representation and warranty by such Stockholder that the prospectus delivered by such Stockholder does not as of the time of such sale contain any untrue statement of a material fact relating to the information expressly provided in writing by such Stockholder for inclusion in such prospectus and that such prospectus does not as of the time of such sale omit to state any material fact relating to the information expressly provided in writing by such Stockholder for inclusion in such prospectus necessary to make the statements in such prospectus, in light of the circumstances under which they were made, not misleading; and

(e) no Stockholder shall use, distribute or otherwise disseminate any “free writing prospectus”, as defined in Rule 405 under the Securities Act, in connection with the sale of Registrable Shares under the Shelf Registration Statement, without the prior written consent of the Company.

Section 4.2 Vacancy and Removal.

(a) Each of the parties hereto hereby irrevocably acknowledges and consents that any legal action or proceeding brought with respect to any of the obligations arising under or relating to this Agreement may be brought in the courts of the State of New York, County of New York or in the United States District Court for the Southern District of New York and each of the parties hereto hereby irrevocably submits to and accepts with regard to any such action or proceeding, for itself and in respect of its property, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts. Each party hereby further irrevocably waives any claim that any such courts lack jurisdiction over such party, and agrees not to plead or claim, in any legal action or proceeding with respect to this Agreement or the transactions contemplated hereby brought in any of the aforesaid courts, that any such court lacks jurisdiction over such

party. Each party irrevocably consents to the service of process in any such action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to such party, at its address for notices set forth in Section 5.4, such service to become effective ten (10) days after such mailing. Each party hereby irrevocably waives any objection to such service of process and further irrevocably waives and agrees not to plead or claim in any action or proceeding commenced hereunder or under any other documents contemplated hereby that service of process was in any way invalid or ineffective. Subject to Section 5.7(b), the foregoing shall not limit the rights of any party to serve process in any other manner permitted by law. The foregoing consents to jurisdiction shall not constitute general consents to service of process in the State of New York for any purpose except as provided above and shall not be deemed to confer rights on any Person other than the respective parties to this Agreement.

(b) Each of the parties hereto hereby waives any right it may have under the laws of any jurisdiction to commence by publication any legal action or proceeding with respect to this Agreement. To the fullest extent permitted by applicable Law, each of the parties hereto hereby irrevocably waives the objection which it may now or hereafter have to the laying of the venue of any suit, action or proceeding arising out of or relating to this Agreement in any of the courts referred to in Section 5.7(a) and hereby further irrevocably waives and agrees not to plead or claim that any such court is not a convenient forum for any such suit, action or proceeding.

(c) The parties hereto agree that any judgment obtained by any party hereto or its successors or assigns in any action, suit or proceeding referred to above may, in the discretion of such party (or its successors or assigns), be enforced in any jurisdiction, to the extent permitted by applicable Law.

(d) The parties hereto agree that the remedy at law for any breach of this Agreement may be inadequate and that should any dispute arise concerning any matter hereunder, this Agreement shall be enforceable in a court of equity by an injunction or a decree of specific performance. Such remedies shall, however, be cumulative and nonexclusive, and shall be in addition to any other remedies which the parties hereto may have.

(e) The prevailing party or parties in any legal action or proceeding brought with respect to any of the obligations arising under or relating to this Agreement shall be entitled to receive from the losing party or parties all costs and expenses, including reasonable counsel fees, incurred by the prevailing party or parties.

Section 5.8 Waiver of Jury Trial.

Each of the Company and each Stockholder hereby waives, to the fullest extent permitted by applicable Law, any right it may have to a trial by jury in respect of any litigation as between the parties directly or indirectly arising out of, under or in connection with this Agreement or the transactions contemplated hereby or disputes relating hereto. Each of the Company and each Stockholder (i) certifies that no representative, agent or attorney of the Company or such Stockholder has represented, expressly or otherwise that the Company or such Stockholder, as the case may be, would not, in the event of litigation, seek to enforce the foregoing waiver and (ii) acknowledges that it, the other Stockholders and the Company have

been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 5.8.

Section 5.9 Third Party Beneficiaries.

Each party hereto intends that this Agreement shall not benefit or create any right or cause of action in or on behalf of any Person other than the parties hereto.

Section 5.10 Confidentiality.

Each Stockholder hereby agrees that throughout the term of this Agreement it shall keep (and shall use all commercially reasonable efforts to cause its directors, officers, general and limited partners, employees, representatives and outside advisors and its Affiliates to keep) all non-public information received by it relating to the Company (including any such information received prior to the date hereof) confidential except information which (a) becomes known to such Stockholder from a source, other than the Company, its directors, officers, employees, representatives or outside advisors, which source, to the actual knowledge of such Stockholder, is not obligated to the Company to keep such information confidential or (b) is or becomes generally available to the public through no breach of this Agreement by such Stockholder. Each of the Company and each Stockholder agrees that (i) such non-public information may be communicated to the directors, officers, general and limited partners, employees, representatives, outside advisors and Affiliates of such Stockholder and (ii) such Stockholder will use all commercially reasonable to cause its directors, officers, general and limited partners, employees, representatives, outside advisors or Affiliates to keep such non-public information confidential. Notwithstanding the foregoing, a Stockholder may disclose non-public information if required to do so upon request for disclosure pursuant to a federal or state freedom of information statute or by a court of competent jurisdiction or by any governmental agency; provided however, that, to the extent permitted by law, prompt notice of such required disclosure be given to the Company prior to the making of such disclosure so that the Company may seek a protective order or other appropriate remedy. In the event that such protective order or other remedy is not obtained, the Stockholder required to disclose the non-public information will disclose only that portion which such party is legally required to be disclosed and will request that confidential treatment be accorded such portion of the non-public information.

Section 5.11 Expenses.

The Company shall reimburse each of the respective members of its Board who are not employees of the Company for their reasonable travel and out-of-pocket expenses incurred in connection with their serving on the Board. Employees of the Company who incur expenses in connection with their attendance of meetings of the Board in the performance of their duties shall also be reimbursed in accordance with the Company’s usual expense reimbursement policies.

Section 5.12 Amendments; Waivers.

No provision of this Agreement may be amended, modified or waived without the prior written consent of the holders of more than fifty percent (50%) of the issued and

outstanding Qualifying Securities, collectively. Notwithstanding the foregoing, the addition of parties to this Agreement in accordance with its terms shall not be deemed to be an amendment, modification or waiver requiring the consent of any Stockholder.

Section 5.13 No Strict Construction.

The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event any ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by all parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

Section 5.14 Specific Performance.

Each of the Company and each Stockholder agrees that irreparable damages would occur to the Company or such Stockholder, as the case may be, if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that each of the Company and each Stockholder shall be entitled to seek an injunction or injunctions to prevent actual breaches of this Agreement by the Company or the Stockholders, as the case may be, and to enforce specifically the terms and provisions hereof in the courts referenced in Section 5.7 (or, on a preliminary basis in order to preserve the status quo pending a decision of the courts referenced in Section 5.7, or in order to enforce a judgment of the courts referenced in Section 5.7, in any court of competent jurisdiction), in addition to having any other remedies to which the Company or such Stockholder is entitled at law or in equity and without the necessity of proving damages or posting a bond or other security.
