Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Solicitation Agent and Dealer Manager or any of its affiliates, the Company acknowledges and agrees that: (i) nothing herein shall create a fiduciary or agency relationship between the Company, on the one hand, and the Solicitation Agent and Dealer Manager, on the other hand; (ii) the relationship between the Company, on the one hand, and the Solicitation Agent and Dealer Manager, on the other hand, is entirely and solely commercial, based on arm’s-length negotiations; and (iii) any obligations that the Solicitation Agent and Dealer Manager may have to the Company shall be limited to those specifically stated herein.

Wells Fargo shall not have any liability in tort, contract or otherwise to the Company or to any of its affiliates for any act or omission on the part of any securities broker, dealer, bank, trust company or nominee or any other person except to the extent that such liability arises out of gross negligence or the willful misconduct of Wells Fargo.

(f) The Company acknowledges that Wells Fargo and its affiliates are engaged in a broad range of securities activities and financial services. In the ordinary course of Wells Fargo’s business, Wells Fargo or its affiliates may at any time hold long or short positions, and may trade or otherwise effect transactions, for their own account or the accounts of customers, in debt or equity securities of the Company or its affiliates.

(k) Other than the Offer Documents, no solicitation material will be used in connection with the Offer or filed with any federal, state, local or foreign governmental or regulatory agency or authority, including the Securities and Exchange Commission (the “Commission”), by or on behalf of the Company without the Solicitation Agent and Dealer Manager’s prior approval (which approval will not be unreasonably withheld).

(l) In the event that the Company is required, or considers it advisable, to amend or supplement the Offer Documents or make any additional filings, including to amend prior filings, with any governmental or regulatory agency or authority (including the Commission), then it shall not make such amendment or supplement or filing without the Solicitation Agent and Dealer Manager’s prior approval (which approval will not be unreasonably withheld).

If Wells Fargo resigns prior to the dissemination of any such release, communication or material, no reference shall be made therein to Wells Fargo despite any prior written approval that may have been given therefor, except as otherwise required by law (in which case the appropriate party shall so advise Wells Fargo in writing prior to such use and shall consult with Wells Fargo with respect to the form and timing of disclosure). Wells Fargo hereby approves the references to it in the Offer Materials as in existence on the date hereof.

-4-

(o) No statements made or advice rendered by the Solicitation Agent and Dealer Manager in connection with the services performed by the Solicitation Agent and Dealer Manager pursuant to this Agreement will be quoted by, nor will any such statements or advice be referred to, in any report, document, release or other communication, whether written or oral, prepared, issued or transmitted by the Company or any person or entity controlling, controlled by or under common control with the Company or any director, officer, member, manager, employee, agent or representative of any such person, without the prior written authorization of the Solicitation Agent and Dealer Manager, which may be given or withheld in its sole discretion, except to the extent required by law (in which case the appropriate party shall so advise the Solicitation Agent and Dealer Manager in writing prior to such use and shall consult with the Solicitation Agent and Dealer Manager with respect to the form and timing of disclosure).

(p) The Company will promptly furnish the Solicitation Agent and Dealer Manager with as many copies of the Offer Documents as the Solicitation Agent and Dealer Manager reasonably requests.

(b) the transactions contemplated by the Agreement or the performance by the Solicitation Agent and Dealer Manager of its obligations thereunder or services contemplated thereby, or any pending or threatened action, claim, litigation, investigation (including, without limitation, any governmental or regulatory investigation) or proceedings relating to the foregoing (each and collectively, “Proceedings”), except, in the case of this clause (b), to the extent such Losses are found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted solely from gross negligence or willful misconduct of such Indemnified Party, regardless of whether any such Indemnified Party is a party thereto,

and to reimburse such Indemnified Party for any reasonable legal or other reasonable out-of-pocket expenses as they are incurred by such Indemnified Party in connection with the investigation of, preparation for or defense of any pending or threatened claim or any action or proceeding arising therefrom.

No Indemnified Party shall have any liability to the Company or any officer, director, counsel, agent, employee or affiliate thereof in connection with the services rendered pursuant to the Agreement except for any liability for Losses that are found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted solely from such Indemnified Party’s gross negligence or willful misconduct.

In case any Proceeding shall be brought or asserted against any Indemnified Party with respect to which indemnity may be sought from the Company hereunder, such Indemnified: Party shall promptly notify the Company in writing; provided that (a) the failure to give such notice shall not relieve the Company of its obligations pursuant to this Annex A unless and only to the extent such failure to give notice results in the loss or compromise of any substantial rights or defenses of the Company, and (b) such failure to notify the Company will not relieve the Company from any liability which it may have to such Indemnified Party otherwise than on account of this Annex A. Upon receiving such notice, the Company will be entitled to participate in any such Proceeding and to assume at its sole expense the defense thereof, with counsel reasonably satisfactory to such Indemnified Party, and, after written notice from the Company to such Indemnified Party of its election so to assume the defense thereof, the Company shall not be liable to such Indemnified Party hereunder for legal expenses of other counsel subsequently incurred by such Indemnified Party in connection with the defense thereof (other than reasonable costs of investigation) unless (i) the Company shall not have employed counsel reasonably satisfactory to

A-1

such Indemnified Party to represent such Indemnified Party within a reasonable time after notice of commencement of the Proceedings, (ii) the Company agrees in writing to pay such fees and expenses, (iii) the Company fails to assume such defense, or (iv) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Company or its affiliates and such Indemnified Party shall have reasonably concluded, based on advice of outside counsel, that there may be legal defenses available to it which are different from or additional to those available to the Company or its affiliates; it being understood, however, that the Company shall not, in connection with any one such Proceeding or separate but substantially similar or related Proceedings arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for all Indemnified Parties, which firm shall be designated in writing by the Solicitation Agent and Dealer Manager.

The Company shall not, without the prior written consent of the Solicitation Agent and Dealer Manager, settle or compromise or consent to the entry of any judgment in any Proceeding in respect of which indemnification has been sought pursuant to this Annex A, unless such settlement, compromise or consent includes an unconditional release from the party bringing such Proceeding of each Indemnified Party from all liability arising out of such Proceeding and does not include a statement as to an admission of fault, culpability or failure to act by or on behalf of any Indemnified Party. The Company shall not be liable for any settlement of any Proceeding effected by an Indemnified Party without the Company’s written consent but if settled with such consent, the Company agrees, subject to the provisions of this Annex A, to indemnify the Indemnified Party from and against any loss, damage or liability by reason of such settlement.

If for any reason the foregoing indemnification is held unenforceable or otherwise unavailable to any Indemnified Party or insufficient to hold it harmless (other than in accordance with the terms of this Annex A), then the Company shall contribute to the amount paid or payable by such Indemnified Party as a result of such Loss in such proportion as is appropriate to reflect (a) the relative benefits received by the Company or any subsidiary or any parent thereof, on the one hand, and such Indemnified Party on the other hand, or (b) if (but only if) the allocation provided by clause (a) above is unenforceable, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (a) but also the relative fault of the Company or any subsidiary or parent thereof, on the one hand, and such Indemnified Party on the other hand, as well as any relevant equitable considerations. The Company agrees that for the purposes of this paragraph the relative benefits to the Company or any subsidiary or any parent thereof (including their affiliates, officers, directors, employees, agents and controlling persons), on the one hand, and Solicitation Agent and Dealer Manager (including their affiliates, officers, directors, employees, agents and controlling persons), on the other hand, shall be deemed to be in the same proportion as (i) the aggregate principal amount of all the Notes purchased in the Offer bears to (ii) the fee actually paid to the Solicitation Agent and Dealer Manager pursuant to this Agreement. The relative fault of the Company, on the one hand, and the Indemnified Party, on the other hand, relating to an untrue or alleged untrue statement of material fact or the omission or alleged omission to state a material fact 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, or relating to, the Company or the Indemnified Parties and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Notwithstanding the foregoing, to the

A-2

extent permitted by applicable law, in no event shall the Indemnified Parties be liable under the foregoing indemnity, reimbursement and contribution provisions in an amount in excess of the fees actually received by the Solicitation Agent and Dealer Manager under this Agreement.

The indemnity, reimbursement and contribution obligations of the Company under this Annex A shall be in addition to any liability which the Company may otherwise have to an Indemnified Party at common law or otherwise, and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company and any such Indemnified Party. Except as set forth herein, no investigation or failure to investigate by any Indemnified Party shall impair the foregoing indemnification and contribution agreement or any right an Indemnified Party may have.

Capitalized terms used but not defined in this Annex A have the meanings assigned to such terms in the Agreement.
