(b) In connection with the Shelf Registration Statement and any Prospectus required by this Agreement to permit the sale or resale of Transfer Restricted Securities, the Company shall: (i) Use its best efforts to keep such Registration Statement continuously effective during the period required by this Agreement; upon the occurrence of any event that would cause any such Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not be effective and usable for resale of Transfer Restricted Securities during the period required by this Agreement, the Company shall file promptly an appropriate amendment to such Registration Statement, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use its reasonable best efforts to cause such amendment to be declared effective and such Registration Statement and the related Prospectus to become usable for their intended purposes as soon as practicable thereafter.

If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or Blue Sky laws, the Company shall use its reasonable best efforts to obtain the withdrawal or lifting of such order at the earliest possible time.

(vii) If requested by any selling Holders or the underwriter(s), if any, promptly incorporate in any Registration Statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders and underwriter(s), if any, may reasonably request to have included therein, including, without limitation, information relating to the "Plan of Distribution" of the Transfer Restricted Securities, information with respect to the principal amount of Transfer Restricted Securities being sold to such underwriter(s), the purchase price being paid therefor and any other terms of the offering of the Transfer Restricted Securities to be sold in such offering; and make all required filings of such Prospectus supplement or post-effective amendment as soon as practicable after the Company is notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment.

(xii) Cooperate with the selling Holders and the underwriter(s), if any, to facilitate the timely preparation and delivery of certificates representing Transfer Restricted Securities to be sold and not bearing any restrictive legends; and enable such Transfer Restricted Securities to be in such denominations and registered in such names as the Holders or the underwriter(s), if any, may request at least two Business Days before any sale of Transfer Restricted Securities made by such underwriter(s). (xiii) Use its reasonable best efforts to cause the Transfer Restricted Securities covered by the Registration Statement to be registered with or approved by such other U.S. governmental agencies or authorities as may be necessary to enable the seller or sellers thereof or the underwriter(s), if any, to consummate the disposition of such Transfer Restricted Securities.

Indemnification and Contribution. (a) The Company and the Subsidiaries (as defined in the Purchase Agreement), jointly and severally, agree to indemnify and hold harmless: (i) each Holder; (ii) each person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any Holder (any of the persons referred to in this clause (ii) being referred to as a "controlling person"); and (iii) the respective officers, directors, partners, employees, representatives and agents of any Holder or any controlling person (any person referred to in clause (i), (ii), or (iii) may hereinafter be referred to as an "Indemnified Holders"), against any losses, claims, damages or liabilities, joint or several, to which such Indemnified Holder may become subject under the Securities Act, the Exchange Act or otherwise, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of any material fact contained in (A) in any Registration Statement or Prospectus or in any amendment or supplement thereto or (B) any application or 9 other document, or any amendment or supplement thereto, executed by the Company or any Subsidiary or based upon written information furnished by or on behalf of the Company or any Subsidiary filed in any jurisdiction in order to qualify the Common Stock issued upon conversion of the Debentures under the securities or "Blue Sky" laws thereof or filed with the Commission or any securities association or securities exchange (each an "Application"); or (ii) the omission or alleged omission to state, in such Registration Statement or Prospectus or any amendment or supplement thereto, or in any Application, a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and will reimburse, as incurred, each Indemnified Holder for any legal or other expenses reasonably incurred by such Indemnified Holder or controlling person in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, neither the Company nor any of the Subsidiaries will be liable in any such case to the extent that any such loss, claim, damage, or liability is finally judicially determined to arise out of or be based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement or Prospectus or amendment or supplement thereto or Application in reliance upon and in conformity with written information furnished to the Company through the Holders by or on behalf of any Holder (or its related Indemnified Holder) specifically for use therein. This indemnity agreement will be in addition to any liability that the Company and the Subsidiaries may otherwise have to the Indemnified Holders. The Company and the Subsidiaries shall not be liable under this Section 6 for any settlement of any claim or action effected without their consent, which shall not be unreasonably withheld. (b) Each Holder, severally and not jointly, will indemnify and hold harmless each of the Company and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Company or any such controlling person may become subject under the Securities Act, the Exchange Act, or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement or the Prospectus or any amendment or supplement thereto or any Application or (ii) the omission or the 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 was made in reliance upon and in conformity with written information furnished to the Company through the Holders by or on behalf of any Holder or its related Indemnified Holder specifically for use therein; and, subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any legal or other expenses incurred by the Company or any controlling person in connection with investigating or defending against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability that any Holder may otherwise have to the indemnified parties. No Holder shall be liable under this Section 6 for any settlement of any claim or action effected without its consent, which shall not 10 be unreasonably withheld. In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the proceeds received by such Holder upon the sale of Transfer Restricted Securities giving rise to such indemnification obligation. (c) Promptly after receipt by an indemnified party under this Section 6 of notice of the commencement of any action for which such indemnified party is entitled to indemnification under this Section 6, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 6, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party (i) will not relieve it from any liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraphs (a) and (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, that if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it and other indemnified parties that are different from or additional to those available to the indemnifying party or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action, then, in each such case, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 6 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by the Holders in the case of paragraph (a) of this Section 6 or the Company in the case of paragraph (b) of this Section 6, representing the indemnified parties under such paragraph (a) or paragraph (b), as the case may be, who are parties to such action or actions) or (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the consent of the indemnifying party, unless such 11 indemnified party waived in writing its rights under this Section 6, in which case the indemnified party may effect such a settlement without such consent. (d) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 6 is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the Company and the Subsidiaries on the one hand and any Holder on the other from such Holder's sale of Transfer Restricted Securities or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the Company and the Subsidiaries on the one hand and such Holder on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative fault of the parties 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 relates to information supplied by the Company or the Subsidiaries on the one hand or such Holder on the other, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission, and any other equitable considerations appropriate in the circumstances. The Company, the Subsidiaries and each Holder of Transfer Restricted Securities agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d). Notwithstanding the provisions of this Section 6(d), none of the Holders (or any of their related Indemnified Holders) shall be required to contribute any amount in excess of the amount by which the total discount received by such Holder with respect to the Common Stock issued upon conversion thereof exceeds the amount of any damages which such Holder has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. 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. For purposes of this paragraph (d), each person, if any, who controls any Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Holder, and each person, if any, who controls the Company or any Subsidiary within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company. 7. Rule 144A.
