(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that (i) the Company may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Bank (and any attempted assignment or transfer by the Company without such consent shall be null and void) and (ii) no Bank may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective 4 successors and assigns permitted hereby, Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Agent and the Banks) any legal or equitable right, remedy or claim under or by reason of this Agreement. (b)(i) Subject to the conditions set forth in paragraph (b)(ii) below, any Bank may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of: (A) the Company, provided that no consent of the Company shall be required for an assignment to a Bank, an Affiliate of a Bank, an Approved Fund or, if an Event of Default under clause (a), (f) or (g) of Section 10.01 has occurred and is continuing, any other assignee; and (B) the Agent, provided that no consent of the Agent shall be required for an assignment of any Commitment to an assignee that is a Bank with a Commitment immediately prior to giving effect to such assignment. (ii) Assignments shall be subject to the following additional conditions: (A) except in the case of an assignment to a Bank or an Affiliate of a Bank or an assignment of the entire remaining amount of the assigning Bank's Commitment or Loans, the amount of the Commitment or Loans of the assigning Bank subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Agent) shall not be less than $10,000,000 unless each of the Company and the Agent otherwise consent, provided that no such consent of the Company shall be required if an Event of Default under clause (a), (f) or (g) of Section 10.01 has occurred and is continuing; (B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Bank's rights and obligations under this Agreement; (C) the parties to each assignment shall execute and deliver to the Agent an Assignment and Assumption, together with a processing and recordation fee of $2,500; and (D) the assignee, if it shall not be a Bank, shall deliver to the Agent an Administrative Questionnaire. (iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Bank under this Agreement, and the assigning Bank thereunder shall, to the extent of 5 the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Bank's rights and obligations under this Agreement, such Bank shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 4.06, 5.01, 5.05 and 12.03). Any assignment or transfer by a Bank of rights or obligations under this Agreement that does not comply with this Section 12.06 shall be treated for purposes of this Agreement as a sale by such Bank of a participation in such rights and obligations in accordance with paragraph (c) of this Section. (iv) The Agent, acting for this purpose as an agent of the Company, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Banks, and the Commitment of, and principal amount of the Loans and Letters of Credit owing to, each Bank pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and the Company, the Agent and the Banks may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Company and any Bank, at any reasonable time and from time to time upon reasonable prior notice. (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Bank and an assignee, the assignee's completed Administrative Questionnaire (unless the assignee shall already be a Bank hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. (c)(i) Any Bank may, without the consent of the Company and the Agent, sell participations to one or more banks or other entities (a "Participant") in all or a portion of such Bank's rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Bank's obligations under this Agreement shall remain unchanged, (B) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Company, the Agent and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Bank sells such a participation shall provide that such Bank shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Bank will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 12.06(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Company agrees that each Participant shall be entitled to receive additional amounts under Section 5 on the same basis as if it were a Bank and be indemnified under Section 12.03 as if it were a Bank. Each agreement creating any 6 participation must include an agreement by the participant to be bound by the provisions of Section 12.15. (ii) A Participant shall not be entitled to receive any greater payment under Section 4.06 or 5.01 than the applicable Bank would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Company's prior written consent. A Participant that is a corporation organized under the laws of a jurisdiction outside the United States of America shall not be entitled to the benefits of Section 4.06 unless the Company is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Company, to comply with Section 4.06(d) as though it were a Bank. (d) Any Bank may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Bank, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Bank from any of its obligations hereunder or substitute any such pledgee or assignee for such Bank as a party hereto. 1.13 Annex I.
