(a) The Company agrees to indemnify and hold harmless the Remarketing Agents, their respective affiliates, directors, officers, employees and agents, and each person, if any, who controls the Remarketing Agents within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Remarketing Agents, affiliate, director, officer, employee, agent or controlling person may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment or supplement thereto, including any information deemed to be a part thereof pursuant to Rule 430B under the Securities Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) any untrue statement or alleged untrue statement of a material fact included in any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or in any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and to reimburse the Remarketing Agents, their respective affiliates, officers, directors, employees, agents and controlling persons for any and all expenses (including the reasonable fees and disbursements of counsel chosen by the Remarketing Agents) as such expenses are reasonably incurred by such Remarketing Agents, affiliate, officer, director, employee, agent or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense

15

or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Remarketing Agents expressly for use in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto). The indemnity agreement set forth in this Section 7(a) shall be in addition to any liabilities that the Company may otherwise have.

The Company agrees that no indemnified party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to the Company or its respective security holders or creditors relating to or arising out of the engagement of any Remarketing Agent pursuant to, or the performance by any Remarketing Agent of services contemplated by this Agreement, except to the extent that any loss, claim, damage, liability or expense resulted from the willful misconduct, gross negligence or bad faith of the Remarketing Agents.

(b) The Remarketing Agents agree, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, or any such director, officer or controlling person may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment or supplement thereto, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or in any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, and only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, such Preliminary Prospectus, such Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by the Remarketing Agents expressly for use therein; and to reimburse the Company, such director, officer or controlling person for any and all expenses (including the reasonable fees and disbursements of counsel chosen by the Company) as such expenses are reasonably incurred by the Company, such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The indemnity agreement set forth in this Section 7(b) shall be in addition to any liabilities that each Remarketing Agent may otherwise have.

16

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure to so notify the indemnifying party (i) will not relieve it from 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 liability other than the indemnification obligation provided in paragraph (a) or (b) above. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party; provided , however, such indemnified party shall have the right to employ its own counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party, unless: (i) the employment of such counsel has been specifically authorized by the indemnifying party; (ii) the indemnifying party has failed promptly to assume the defense and employ counsel reasonably satisfactory to the indemnified party; or (iii) the named parties to any such action (including any impleaded parties) include both such indemnified party and the indemnifying party or any affiliate of the indemnifying party, and such indemnified party shall have reasonably concluded that either (x) there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party or such affiliate of the indemnifying party or (y) a conflict may exist between such indemnified party and the indemnifying party or such affiliate of the indemnifying party (it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to a single firm of local counsel) for all such indemnified parties, which firm shall be designated in writing by (i) the Remarketing Agents, in the case of indemnification pursuant to Section 7(a) hereof, or (ii) the Company, in the case of indemnification pursuant to Section 7(b) hereof, and that all such reasonable fees and expenses shall be reimbursed as they are incurred).

17

(d) The indemnifying party under this Section 7 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there is a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 7(c) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

Section 8. Contribution.

(a) If the indemnification provided for in Section 7 hereof is for any reason unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Remarketing Agents, on the other hand, from the remarketing of the Remarketed Notes pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Remarketing Agents, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Remarketing Agents, on the other hand, in connection with the remarketing of the Remarketed Notes pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the remarketing of the Remarketed Notes pursuant to this Agreement (before deducting expenses) received by the Company, and the total fees received by the Remarketing Agents. The relative fault of the Company, on the one hand, and the Remarketing Agents, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue

18

statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or the Remarketing Agents, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(b) The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 7(c) hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 7(c) hereof with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 8; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 7(c) hereof for purposes of indemnification.

(c) The Company and the Remarketing Agents agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Remarketing Agents 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 8.

(d) Notwithstanding the provisions of this Section 8, the Remarketing Agents shall not be required to contribute any amount in excess of the Remarketing Fee received by the Remarketing Agents in connection with the Remarketing. 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 Section 8, each director, officer, employee and agent of a Remarketing Agent and each person, if any, who controls a Remarketing Agent within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Remarketing Agents, and each director of the Company, each officer of the Company who signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company.

Section 9. Resignation And Removal Of The Remarketing Agents.

Each of the Remarketing Agents may resign and be discharged from its duties and obligations hereunder, and the Company may remove either of the Remarketing Agents, by giving 10 days’ prior written notice, in the case of a resignation, to the Company, the remaining Remarketing Agent and the Purchase Contract Agent, and, in the case of a removal, to the removed Remarketing Agent and the Purchase Contract Agent; provided, however, that no such resignation nor any such removal shall become effective (i) unless there is one remaining Remarketing Agent or (ii) if (i) does not apply, until the Company shall have

19

appointed at least one nationally recognized broker-dealer as a successor Remarketing Agent and such successor Remarketing Agent shall have entered into a remarketing agreement with the Company, in which it shall have agreed to conduct the Remarketing in accordance with the Transaction Documents in all material respects.

In any such case, the Company will use commercially reasonable efforts to appoint a successor Remarketing Agent and enter into such a remarketing agreement with such person as soon as reasonably practicable. The provisions of Section 7 and Section 8 shall survive the resignation or removal of a Remarketing Agent pursuant to this Agreement.

Section 10. Dealing in Securities.

The Remarketing Agents, when acting as the Remarketing Agents or in their individual or any other capacity, may, to the extent permitted by law, buy, sell, hold and deal in any of the Remarketed Notes, Corporate Units, Treasury Units or any of the securities of the Company (collectively, the “ Securities ”). The Remarketing Agents may exercise any vote or join in any action which any beneficial owner of such Securities may be entitled to exercise or take pursuant to the Indenture with like effect as if it did not act in any capacity hereunder. The Remarketing Agents, in their individual capacity, either as principal or agent, may also engage in or have an interest in any financial or other transaction with the Company as freely as if they did not act in any capacity hereunder.

Section 11. Remarketing Agents’ Performance; Duty Of Care.

The duties and obligations of the Remarketing Agents shall be determined solely by the express provisions of the Transaction Documents. No implied covenants or obligations of or against the Remarketing Agents shall be read into any of the Transaction Documents. In the absence of bad faith on the part of the Remarketing Agents, the Remarketing Agents may conclusively rely upon any document furnished to them, as to the truth of the statements expressed in any of such documents. The Remarketing Agents shall be protected in acting upon any document or communication reasonably believed by them to have been signed, presented or made by the proper party or parties except as otherwise set forth herein. The Remarketing Agents shall have no obligation to determine whether there is any limitation under applicable law on the Reset Rate on the Notes or, if there is any such limitation, the maximum permissible Reset Rate on the Notes, and they shall rely solely upon written notice from the Company (which the Company agrees to provide prior to the third Business Day before the applicable Remarketing Date) as to whether or not there is any such limitation and, if so, the maximum permissible Reset Rate. The Remarketing Agents, acting under this Agreement, shall incur no liability to the Company or to any holder of Remarketed Notes in their individual capacities or as Remarketing Agents for any action or failure to act, on their part in connection with a Remarketing or otherwise, except if such liability is (i) judicially determined to have resulted from

20

their failure to comply with the material terms of this Agreement or bad faith, gross negligence or willful misconduct on their part or (ii) determined pursuant to Section 7 or 8 of this Agreement. The provisions of this Section 11 shall survive the termination of this Agreement and shall survive the resignation or removal of a Remarketing Agent pursuant to this Agreement.

Section 12. Termination.

This Agreement shall automatically terminate (i) as to a Remarketing Agent on the effective date of the resignation or removal of such Remarketing Agent pursuant to Section 9 and (ii) on the earlier of (x) the occurrence of a Termination Event and (y) the Business Day immediately following the Purchase Contract Settlement Date. If this Agreement is terminated pursuant to any of the other provisions hereof, except as otherwise provided herein, the Company shall not be under any liability to the Remarketing Agents and the Remarketing Agents shall not be under any liability to the Company, except that if this Agreement is terminated by the Remarketing Agents because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, the Company will reimburse the Remarketing Agents for all of their out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by them. Notwithstanding any termination of this Agreement, in the event there has been a Successful Remarketing, the obligations set forth in Section 4 hereof shall survive and remain in full force and effect until all amounts payable under said Section 4 shall have been paid in full. In addition, Sections 7, 8 and 11 hereof shall survive the termination of this Agreement or the resignation or removal of a Remarketing Agent.

Additionally, the Remarketing Agents are not advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction.
