If requested by the underwriters for any underwritten offering by the Holders to be conducted pursuant to Section 2.2.1 hereof, the Company will enter into an underwriting agreement with such underwriters for such offering, such agreement to be in customary form for offerings of this type and acceptable to the Holders, whose acceptance shall not be unreasonably withheld, to contain such representations and warranties by the Company and such other terms as are generally prevailing in agreements of this type, including, without limitation, representations and indemnities by the Company and other customary indemnifications. For illustrative purposes, the representations and warranties and such other terms contained therein and agreed to by the Company in that certain Registration Rights Agreement, dated as of December 17, 2004, between the Company and Credit Suisse First Boston LLC, shall be deemed customary; provided, however, the parties acknowledge and agree that certain additional representations and warranties and other terms may be added or changed based on the facts and circumstances at the time of the Company's entering into the underwriting agreement.

Any discretionary waiver or termination of the requirements under the foregoing provisions made by the managing underwriter shall apply to each seller of Registrable Securities on a pro rata basis in accordance with the number of Registrable Securities held by each seller. 8 2.2.6 Selection of Underwriters. In an underwritten offering of Registrable Securities effected pursuant to this Section 2.2, the Notifying Holders shall select the investment banking firm or firms to manage the underwritten offering; provided, however, that such selection shall be subject to the consent of the Company, which consent shall not be unreasonably withheld. 2.2.7 Participation in Underwritten Offerings.

Each Holder shall advise the Company in writing within five (5) Business Days after the date of receipt of the Company Notice, specifying the number of Registrable Securities, if any, such Receiving Holders seek to include in such underwritten offering.

If the managing underwriter of the underwritten offering pursuant to which Registrable Securities are included pursuant to this Section 2.3 shall advise the Holders and the Company in writing that, in its opinion, the number of securities requested to be included in such underwritten offering (including securities to be sold by the Company or by other Persons not holding Registrable Securities) exceeds the number which can be sold in such underwritten offering within an acceptable price range, the Company will include in such underwritten offering, to the extent of the number which the Company is so advised can be sold in such underwritten offering, (i) first, securities of the Company that the Company proposes to sell and (ii) second, securities of the Company held by other Persons having registration rights proposed to be included in such registration by the holders thereof and Registrable Securities proposed to be included in such registration by the Holders thereof, allocated, if necessary, on a pro rata basis in accordance with the number of shares proposed to be included in such registration by such other Persons and/or such Holders, as applicable. 2.3.4 Expenses.

The Company agrees to indemnify and reimburse, to the fullest extent permitted by law, each underwriter of Registrable Securities, each seller of Registrable Securities, and each of its employees, advisors, agents, representatives, partners, officers, and directors and each Person who controls such seller (within the meaning of the Securities Act or the Exchange Act) and any agent or investment advisor thereof (collectively, the "Seller Affiliates") (A) against any and all losses, claims, damages, liabilities, and expenses, joint or several (including, without limitation, attorneys' fees and disbursements except as limited by Section 2.5.3 hereof) based upon, arising out of, related to or resulting from any untrue or alleged untrue statement of a material fact contained in any registration statement, prospectus, or preliminary prospectus or any amendment thereof or supplement thereto, or any omission or alleged omission of a material fact 14 required to be stated therein or necessary to make the statements therein in light of the circumstances under which they were made not misleading, (B) against any and all loss, liability, claim, damage, and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon, arising out of, related to or resulting from any such untrue statement or omission or alleged untrue statement or omission and (C) against any and all costs and expenses (including reasonable fees and disbursements of counsel) as may be reasonably incurred in investigating, preparing, or defending against any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon, arising out of, related to or resulting from any such untrue statement or omission or alleged untrue statement or omission, or such violation of the Securities Act or Exchange Act, to the extent that any such expense or cost is not paid under subparagraph (A) or (B) above; provided, however, that the Company shall not be liable in any such case to the extent that such statements are made in reliance upon and in strict conformity with information furnished in writing to the Company by such seller or any Seller Affiliate for use therein or arise from such seller's or any Seller Affiliate's failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such seller or Seller Affiliate with a sufficient number of copies of the same. The reimbursements required by this Section 2.5.1 will be made by periodic payments during the course of the investigation or defense, as and when bills are received or expenses incurred. 2.5.2 Indemnification by the Seller. In connection with any registration statement in which a seller of Registrable Securities is participating, each such seller 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 fullest extent permitted by law, each such seller will indemnify the Company and its directors and officers and each Person who controls the Company (within the meaning of the Securities Act or the Exchange Act) against any and all losses, claims, damages, liabilities, and expenses (including, without limitation, reasonable attorneys' fees and disbursements except as limited by Section 2.5.3 hereof) resulting from any untrue statement or alleged untrue statement of a material fact contained in the registration statement, prospectus, or any 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 in light of the circumstances under which they were made not misleading, but only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission is contained in any information or affidavit so furnished in writing by such seller or any of its Seller Affiliates specifically for inclusion in the registration statement; provided that the obligation to indemnify will be several, not joint and several, among such sellers of Registrable Securities, and the liability of each such seller of Registrable Securities will be in proportion to, and, provided, further, that such liability will be limited to, the net amount received by such seller from the sale of Registrable Securities pursuant to such registration statement; provided, however, that such seller of Registrable Securities shall not be liable in any such case to the extent that prior to the filing of any such registration statement or prospectus or amendment thereof or supplement thereto, such seller has furnished in writing to the Company information expressly for use in such registration statement or prospectus or any amendment thereof or supplement thereto which corrected or made not misleading information previously furnished to the Company. 15 2.5.3 Notice of Claims, etc. Any Person entitled to indemnification hereunder will (A) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give such notice shall not limit the rights of such Person except to the extent that the indemnifying party is actually prejudiced by such failure to give notice) and (B) unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided, however, that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (X) the indemnifying party has agreed to pay such fees or expenses, or (Y) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person. In the event the indemnified party believes such a conflict of interest exists, the indemnifying party shall indemnify the indemnified party for all costs and expenses of separate counsel for the indemnified party in accordance with Sections 2.5.1 or 2.5.2 hereof) above, as applicable. If such defense is not assumed by the indemnifying party as permitted hereunder, 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). If such defense is assumed by the indemnifying party pursuant to the provisions hereof, such indemnifying party shall not settle or otherwise compromise the applicable claim unless (1) such settlement or compromise contains a full and unconditional release of the indemnified party or (2) the indemnified party otherwise consents in writing. 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 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, in which event the indemnifying party shall be obligated to pay the reasonable fees and disbursements of such additional counsel or counsels. 2.5.4 Contribution. Each party hereto agrees that, if for any reason the indemnification provisions contemplated by Section 2.5.1 or 2.5.2 hereof are unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities, or expenses (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, liabilities, or expenses (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the actions which resulted in the losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of such indemnifying party 16 and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or indemnified party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided that in no event shall the obligation of any indemnifying party to contribute under this Section 2.5.4 exceed the amount that such indemnifying party would have been obligated to pay by way of indemnification if the indemnification provided for under Sections 2.5.1 or 2.5.2 hereof had been available under the circumstances. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 2.5.4 were determined by pro rata allocation (even if the Holders or any underwriters or all of them were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 2.5.4. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities, or expenses (or actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or, except as provided in Section 2.5.3 hereof, defending any such action or claim. Notwithstanding the provisions of this Section 2.5.4, no Holder shall be required to contribute an amount greater than the dollar amount by which the net proceeds received by such Holder with respect to the sale of any Registrable Securities exceeds the amount of damages which such Holder has otherwise been required to pay by reason of any and all untrue or alleged untrue statements of material fact or omissions or alleged omissions of material fact made in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto related to such sale of Registrable Securities. 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 Holders' obligations in this Section 2.5.4 to contribute shall be several in proportion to the amount of Registrable Securities registered by them and not joint. If indemnification is available under this Section 2.5, the indemnifying parties shall indemnify each indemnified party to the full extent provided in Sections 2.5.1 and 2.5.2 hereof without regard to the relative fault of said indemnifying party or indemnified party or any other equitable consideration provided for in this Section 2.5.4 subject, in the case of the Holders, to the limited dollar amounts set forth in Section 2.5.2 hereof. 2.5.5 The indemnification and contribution 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 officer, director, or controlling Person of such indemnified party and will survive the transfer of securities. 2.6 Suspension of Registration. Notwithstanding anything to the contrary contained herein (other than as set forth in Section 2.1 hereof), for a period or periods not to exceed sixty (60) consecutive calendar days and not to exceed one hundred twenty (120) calendar days in any twelve-month period (each such period, a "Deferral Period"), the Company will not be required to file any registration statement pursuant to this Agreement, file any amendment thereto, 17 furnish any supplement to a prospectus included in a registration statement pursuant to Section 2.4.1(e)(iii) hereof, make any other filing with the SEC, cause any registration statement or other filing with the SEC to become effective, or take any similar action, and any and all sales of Registrable Securities by the Holders pursuant to an effective registration statement shall be suspended: if (i) an event has occurred and is continuing as a result of which any such registration statement or prospectus would, in the Company's reasonable judgment, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) if the Company notifies the Holders that such actions would, in the good faith judgment of outside counsel to the Company, require the disclosure of material non-public information which the Company has a bona fide business purpose for preserving as confidential and which the Company would not otherwise be required to disclose. Upon the termination of the condition described in clauses (i) or (ii) of above, the Company shall give written notice to the Holders and shall promptly file any registration statement or amendment thereto required to be filed by it pursuant to this Agreement, furnish any prospectus supplement or amendment required to be furnished pursuant to Section 2.4.1(e)(iii) hereof, make any other filing with the SEC required of it or terminate any suspension of sales it has put into effect and shall take such other actions to permit registered sales of Registrable Securities as contemplated by this Agreement. The Company shall promptly provide a Suspension Notice, specifying any suspension of registration rights pursuant to this Section 2.6 to (i) prior to the first anniversary of the Effective Time, all Holders and (ii) during the term of the Agreement, all Holders that are Affiliates of the Company, unless in either case such Holders advise the Company in writing that they do not wish to receive Suspension Notices except pursuant to Section 2.1.4 hereof. For the purposes of Sections 2.1.1, 2.3.1 and 4.1 hereof, the occurrence of any Deferral Period pursuant to this Section 2.6 shall cause the third anniversary of the Effective Time to be deemed extended by a number of days equivalent to the duration of any such Deferral Period. ARTICLE 3 RULE 144 -------- 3.1 Current Public Information. With a view to making available to the Holders the benefits of certain rules and regulations of the SEC that may at any time permit the sale of securities to the public without registration, the Company agrees to use its reasonable best efforts to: (i) make and keep public information available, as those terms are defined in Rule 144 under the Securities Act, at all times after the effective date that the Company becomes subject to the reporting requirements of the Securities Act or the Exchange Act; (ii) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); 18 (iii) furnish to any Holder, so long as such Holder owns any Registrable Securities, upon request by such Holder, (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company and (iii) such other reports and documents of the Company and other information in the possession of or reasonably obtainable by the Company as a Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing a Holder to sell any such securities without registration.
