Indemnification. (a) In the event of the registration of any Merger Registrable Securities or any Contingent Registrable Securities under the Securities Act pursuant to this Agreement, the Company will indemnify and hold harmless each Holder thereunder and each Person, if any, who controls the Holders within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities (including reasonable attorneys' fees) or actions in respect thereof ("Losses"), joint or several, to which such Holder or controlling Person may become subject under the Securities Act, or otherwise, insofar as such Losses, arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Merger Registration Statement or the Contingent Registration Statement on the effective date thereof under which such Merger Registrable Securities or Contingent Registrable Securities, as appropriate, were registered under the Securities Act pursuant to this Agreement, any preliminary prospectus distributed with the consent of the Company or final prospectus contained therein, or any amendment or supplement thereof, including the documents incorporated by reference therein, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each such Holder and each such controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss; provided, however, that the Company will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Holder or such controlling Person in writing specifically for use in the Merger Registration Statement or the Contingent Registration Statement, preliminary prospectus, final prospectus or such amendment or supplement thereof, including all documents incorporated by reference therein. (b) In the event of the registration of any Merger Registrable Securities or Contingent Registrable Securities under the Securities Act pursuant to the Agreement, the Holders, jointly and severally, agree to indemnify and hold harmless the Company, its directors, officers, employees and agents, and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act against any and all such Losses to which the Company or such directors, officers, employees, agents or controlling Persons may become subject under the Securities Act or otherwise, and will reimburse the Company, each such director, officer, employee, agent and controlling Person for any legal or any other expenses reasonably incurred by such party in connection with investigating or defending any such Loss, if (a) such Loss arises out of or is based upon any untrue statement or alleged untrue statement of any material fact contained in the Merger Registration Statement or the Contingent Registration Statement, preliminary prospectus, final prospectus or such amendment or supplement thereof, including all documents incorporated by reference therein or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and any such statement or omission of a material fact was made in reliance upon and in conformity with the written information furnished to the Company by or on behalf of the Holders specifically for use in connection with the preparation of the Merger Registration Statement or the Contingent Registration Statement, preliminary prospectus, final prospectus or such amendment or supplement thereof, including all documents incorporated by reference therein, or (b) such Loss arises out of or is based upon the Holder's failure to deliver any required prospectus or otherwise comply with applicable laws regarding the same; provided, however, that the liability of such Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Holder from 6 9 the sale of the Merger Registrable Securities or Contingent Registrable Securities giving rise to such indemnification. (c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party other than under this Section 2.06. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.06 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense and employ counsel or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred, provided that such fees and expenses shall be reimbursed for only one counsel for all indemnified parties in addition to any local counsel. (d) If the indemnification provided for in this Section 2.06 is unavailable to the Company or the Holders or is insufficient to hold them harmless in respect of any losses, claims, damages, liabilities or expenses referred to herein, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and expenses as between the Company on the one hand and each Holder on the other, in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and of each Holder on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and each Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statements of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. No person of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation. 7 10 ARTICLE III Section 3.01.
