Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, within five (5) Business Days after the Indemnified Party's receipt of such request, all information and documentation reasonably requested by the Indemnifying Party with respect to such Loss.

(b) If the indemnification sought pursuant hereto involves a claim made by a Third Party against the Indemnified Party (a "Third Party Claim"), the Indemnifying Party shall be entitled to participate in the defense of such Third Party Claim and, if it so chooses within forty-five (45) days after its receipt of an Indemnification Claim Notice, to assume the defense of such Third Party Claim with counsel selected by the Indemnifying Party; provided, however that the Indemnifying Party shall not be entitled to assume the defense of any Third Party Claim to the extent such claims involve or seek injunctive or other relief that does not involve solely monetary obligations. Should the Indemnifying Party so elect to assume the defense of a Third Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof. If the Indemnifying Party assumes such defense, the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Party, it being understood that the Indemnifying Party shall control such defense. The Indemnifying Party shall be liable for the reasonable fees and expenses of counsel employed by the Indemnified Party for any period during which the Indemnifying Party has not assumed the defense thereof. If the Indemnifying Party chooses to defend or prosecute a Third Party Claim, all of the parties hereto shall cooperate in the defense or prosecution thereof. Such cooperation shall include (i) the retention and (upon the Indemnifying Party's request) the provision to the Indemnifying Party of records and information which are reasonably relevant to such Third Party Claim, and (ii) making relevant employees and agents available on a mutually

convenient basis to provide additional information and explanation of any material provided hereunder; provided, that the Indemnifying Party shall reimburse the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith.

(c) If the Indemnifying Party chooses to defend or prosecute any Third Party Claim, to the extent that it involves any agreement, performance or observance by the Indemnified Party, the Indemnifying Party shall not agree to such agreement, performance of observance without the Indemnified Party's prior written consent (which shall not be unreasonably withheld, conditioned or delayed). Further, with respect to all Losses in connection with Third Party Claims where the Indemnifying Party has assumed the defense or prosecution of the Third Party Claim in accordance with Section 14.5(b) above, the Indemnifying Party shall not be liable for any settlement or other disposition of such Losses by an Indemnified Party that is reached without the written consent of the Indemnifying Party. Whether or not the Indemnifying Party will have assumed the defense of a Third Party Claim, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, such Third Party Claim without the Indemnifying Party's prior written consent (which shall not be unreasonably withheld, conditioned or delayed). If the Indemnifying Party chooses not to defend or prosecute any Third Party Claim, no Indemnified Party shall admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed).

(d) Without limiting Section 14.5(b), any Indemnified Party shall be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment shall be at the Indemnified Party's own expense unless (i) the employment thereof has been specifically authorized by the Indemnifying Party in writing, or (ii) the Indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 14.5(b) (in which case the Indemnified Party shall control the defense). The reasonable and verifiable costs and expenses incurred pursuant to Section 14.5(d)(i) and Section 14.5(d)(ii), including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any Third Party Claim shall be reimbursed on a quarterly basis by the Indemnifying Party, without prejudice to the Indemnifying Party's right to contest the Indemnified Party's right to indemnification and subject to refund in the event the Indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party. Buyer and Seller shall cooperate in reasonable good faith to minimize their respective indemnification obligations with respect to any and all Losses.

Section 15.9 Governing Law. This Agreement will be deemed to have been made in the State of New York and its form, execution, validity, construction and effect will be determined in accordance with the laws of the State of New York, without giving effect to the principles of conflicts of law thereof, and the parties agree to the personal jurisdiction of and venue in any federal court located in the Southern District of New York or state court located in New York County, New York.

Section 15.12 Publicity. Neither party shall make any public announcement concerning, or otherwise publicly disclose, any information with respect to the transactions contemplated by this Agreement or any of the terms and conditions hereof without the prior written consent of the other party, which consent will not be unreasonably withheld, conditioned or delayed. Notwithstanding the foregoing, either party may make any public disclosure concerning the transactions contemplated hereby that in the opinion of such party's counsel may be required by law or the rules of any stock exchange or interdealer quotation service on or through which such party's or its Affiliates' securities trade; provided, however, the party making such disclosure shall provide the non-disclosing party with a copy of the intended disclosure reasonably, and to the extent practicable, prior to public dissemination, and the parties hereto shall coordinate with one another regarding the timing, form and content of such disclosure; and provided, further, Buyer and Seller agree that the form of press release attached hereto as Exhibit I may be issued by Buyer, Seller or either of their respective Affiliates at any time following the Closing.

Section 15.13 Assignment.

(a) Neither party may assign any or all of its rights or obligations under this Agreement without the other party's prior written consent; provided, however, that (i) either party may assign any or all of its rights or obligations under this Agreement to an Affiliate of such party, (ii) Buyer may license, assign, subcontract or delegate to any Affiliate all or part of the rights and obligations of Buyer under this Agreement and (iii) either party may assign all of its rights or obligations under this Agreement to a Third Party to which such party has sold all or substantially all of its assets relating to this Agreement.

(b) In the event that a party assigns any of its rights and obligations hereunder to an Affiliate or Third Party, the assigning party shall, at the request of the non-assigning party, enter into, or cause such Third Party to enter into, such supplemental agreements pursuant to which such Third Party will expressly assume all of the obligations of the assigning party

hereunder. Any assignment to an Affiliate of a party shall not release the assigning or transferring party of its obligations hereunder.
