(ii) any breach of any covenant of Sellers contained in this Agreement and any liability (whether known, unknown, accrued, unaccrued, contingent, matured or unmatured) of Kos Investments and Kos Holdings in existence at the Closing Date other than any item that would give rise to an indemnification claim pursuant to Section 7.01(a)(iii) or Section 7.01(a)(iv) and liability that is discharged in connection with the Closing;

The dates upon which rights to indemnification hereunder terminate are referred to herein as the “Indemnification Expiration Dates”.

SECTION 7.05. Procedures.

(a) Tax Claims. (i) If a claim shall be made by any Taxing Authority, which, if successful, might result in an indemnity payment to any Indemnified Party pursuant to Section 7.01 or 7.02, respectively, or which may result in an adjustment to the Taxes of any Seller, Acquiror or Sellers, as applicable, shall promptly notify the other party in writing of such claim (a “Tax Claim”). If notice of a Tax Claim is not given to the indemnifying party within a sufficient period of time to allow such party to effectively contest such Tax Claim, or in reasonable detail to apprise the indemnifying party of the nature of the Tax Claim, in each case

taking into account the facts and circumstances with respect to such Tax Claim, the indemnifying party shall not be liable to the Indemnified Party.

(ii) With respect to any Tax Claim relating solely to Taxes of Kos Investments or Kos Holdings for a Preclosing Period, Sellers shall control all proceedings in connection with such Tax Claim (including selection of counsel) and, without limiting the foregoing, may in their sole discretion pursue or forego any and all administrative appeals, proceedings, hearings and conferences with any Taxing Authority with respect thereto, and may, in their sole discretion, settle such claim and, if applicable, either pay the Tax claimed and xxx for a refund where applicable Law permits such refund suits or contest the Tax Claim in any permissible manner; provided, however, that Acquiror and counsel of its own choosing and at its own expense shall have the right to participate fully in all aspects of the prosecution or defense of such Tax Claim. Acquiror shall control all proceedings taken in connection with any Tax Claim relating solely to Taxes of Kos Investments and Kos Holdings for a Straddle Period, provided that in such case Acquiror shall not settle any Taxes for the Straddle Period without the prior written consent of Sellers. Acquiror shall control all other proceedings with respect to all other Tax Claims.

(iii) Acquiror, Kos Investments and Kos Holdings shall cooperate with Sellers in contesting any Tax Claim, which cooperation shall include the retention and, upon Sellers’ request, the provision to Sellers of records and information which are reasonably relevant to such Tax Claim, and making employees available on a mutually convenient basis to provide additional information or explanation of any material provided hereunder or to testify at proceedings relating to such Tax Claim.

(b) Third Party Claims. (i) In order for an Indemnified Party to be entitled to any indemnification provided for under Section 7.01 or 7.02, as applicable, in respect of, arising out of or involving a claim made by any person against an Indemnified Party (other than claims relating to Taxes which are subject to clause (a)) (a “Third Party Claim”), such Indemnified Party must notify the indemnifying party in writing of the Third Party Claim promptly following receipt by it of written notice of the Third Party Claim (which notice shall include a reasonably summary of the basis for such claim and an estimate of the applicable Loss to the extent then reasonably determinable). Thereafter, the applicable Indemnified Party shall deliver to the indemnifying party, promptly following receipt by it thereof, copies of all notices and documents (including court papers) received by it from the person asserting the Third Party Claim relating to the Third Party Claim (it being understood that delivery of such notices and documents by one Indemnified Party shall satisfy such obligation for all Indemnified Parties in respect of such notices and documents). Notwithstanding the foregoing, the failure or delay in delivering any items contemplated to be delivered to the indemnifying party in respect of a Third Party Claim pursuant to this paragraph shall only relieve the indemnifying party of its indemnification obligations hereunder in respect of such claim to the extent that it is actually prejudiced by such delay.

(ii) The indemnifying party shall be entitled to participate in the defense of any Third Party Claim and, if they so choose, to assume the defense thereof

with counsel selected by the indemnifying party; provided, however, that (A) such counsel is not reasonably objected to by the applicable Indemnified Party and (B) the indemnifying party shall not have the right to defend any Third Party Claim that seeks, in addition to or in lieu of monetary damages, any injunctive or other equitable relief. If the indemnifying party assumes such defense, each 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 fees and expenses of counsel employed by the Indemnified Parties for any period during which the indemnifying party has not assumed the defense thereof shall be deemed indemnifiable Losses for purposes of Section 7.01. If the indemnifying party chooses to defend or prosecute a Third Party Claim, all the Indemnified Parties shall cooperate in the defense or prosecution thereof. Such cooperation shall include the retention and (upon the indemnifying party’s request) the provision to the indemnifying party of records and information that are reasonably relevant to such Third Party Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Whether or not the indemnifying party assumes the defense of a Third Party Claim, no Indemnified Party shall 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 or delayed). If the indemnifying party assumes the defense of a Third Party Claim, the applicable Indemnified Parties shall agree to any settlement, compromise or discharge of a Third Party Claim that the indemnifying party may recommend and that by its terms provides for full indemnification of the Indemnified Parties in respect of the full amount of the liability in connection with such Third Party Claim, which releases the Indemnified Parties completely in connection with such Third Party Claim and that would not otherwise adversely affect the Indemnified Parties.

(c) Other Claims. In the event any Indemnified Party should have a claim under Section 7.01 or 7.02 that does not involve a Third Party Claim or a claim relating to Taxes (which are subject to clause (a) of this Section 7.05) being asserted against or sought to be collected from such Indemnified Party, the Indemnified Party shall deliver notice of such claim with reasonable promptness to Sellers or Acquiror, as applicable (which notice shall include a reasonable summary of the basis for such claim and an estimate of the amount of the applicable Loss to the extent then reasonably determinable). Notwithstanding the foregoing, the failure or delay in delivering any items contemplated to be delivered to the indemnifying party in respect of any claim pursuant to this paragraph shall only relieve the indemnifying party of its indemnification obligations hereunder in respect of such claim to the extent that it is actually prejudiced by such delay.

SECTION 7.06. Survival. The representations, warranties in this Agreement, and in any document delivered in connection herewith, of or by Sellers shall survive the Closing until the applicable Indemnification Expiration Dates. The representations, warranties in this

Agreement, and in any document delivered in connection herewith, or by Acquiror shall survive until the applicable Indemnification Expiration Dates.

(a) The Escrow Agent shall have no duties or obligations hereunder except those specifically set forth herein and such duties and obligations shall be determined solely by the express provisions of this Agreement. The Escrow Agent shall have no liability under and no duty to inquire as to the provisions of any agreement other than this Agreement. In connection with its duties hereunder, the Escrow Agent shall be protected in acting or refraining from acting upon any written notice, request, consent, certificate, order, affidavit, letter, telegram or other document furnished to it hereunder and believed by it to be genuine and to have been signed or sent by the proper party or parties.

The Escrow Agent shall not be liable for the performance of

-2-

agents selected by it with reasonable care or for anything done, suffered or omitted in good faith by it in accordance with the advice or opinion of any such counsel, accountants or other skilled persons. The Escrow Agent shall have no duty to solicit any payments that may be due it hereunder. The Escrow Agent shall not be liable for any action taken or omitted by it in good faith unless a court of competent jurisdiction determines that the Escrow Agent’s gross negligence or willful misconduct was the primary cause of the loss to an Escrow Party. The Escrow Agent shall not incur any liability for following the instructions set forth in this Agreement or written instructions given by an Escrow Party in accordance with this Agreement.

(b) In the event the Escrow Agent shall be uncertain as to its duties or rights under this Agreement or shall receive any instruction, claim or demand that, in the opinion of the Escrow Agent, is in conflict with the provisions of this Agreement (any of the foregoing, an “Escrow Agent Dispute”), the Escrow Agent shall be entitled to refrain from taking any action with respect to such Escrow Agent Dispute until it shall be directed otherwise by a final and nonappealable order of a court of competent jurisdiction or by an instrument signed by all of the Escrow Parties.

The Acquiror shall be responsible for all such reasonable fees and expenses. The Acquiror shall be liable for the payment of all such fees and expenses incurred by the Escrow Agent, except for such fees and expenses incurred by the Escrow Agent due to (i) the failure of an Escrow Party to comply with any of its obligations hereunder or (ii) the requirement by an Escrow Party that the Escrow Agent perform duties outside the scope of this Agreement, which fees and expenses set forth in the immediately preceding clauses (i) and (ii) shall be paid by the applicable Escrow Party.

The resigning Escrow Agent may appoint a successor Escrow Agent, reasonably acceptable to the Escrow Parties. If a successor Escrow Agent shall not have been appointed within 20 days after such notice of resignation, any of the Escrow Parties or the Escrow Agent, at the expense of the Escrow Parties, may apply to any court of competent jurisdiction to appoint a successor Escrow Agent. Notwithstanding the foregoing, any successor Escrow Agent shall be a financial institution organized under the laws of the United States of America and having a combined capital and surplus of not less than US $100,000,000. Any successor Escrow Agent, however appointed, shall execute and deliver to the predecessor Escrow Agent, with a copy to each of the Escrow Parties, an instrument accepting such appointment, and thereupon such successor Escrow Agent shall, without further act, become fully vested with all the rights, powers, obligations and

-3-

duties of the predecessor Escrow Agent hereunder with the same effect as if originally named the Escrow Agent herein. The Escrow Agent shall have the right to withhold an amount equal to any amount due and owing to the Escrow Agent, plus any reasonable costs and expenses the Escrow Agent reasonably believes may be incurred by the Escrow Agent in connection with termination of this Agreement.
