Prize shall use reasonable efforts to cause each of the holders of Prize Common Stock and of Prize Preferred Stock to execute and deliver the Registration Rights Agreement. 5.15 INDEMNIFICATION AND INSURANCE. (a) Parent and Prize agree that all rights to indemnification now existing in favor of any officers, directors, employees, controlling stockholders or agents of any of the Parent Companies or any of the Prize Companies, as provided in their respective charters or bylaws (or similar organizational documents), and any existing indemnification agreements or arrangements of any of the Parent Companies or any of the Prize Companies, shall survive the Merger and shall continue in full force and effect for a period of not less than six years from the Effective Time (or such longer period as may be provided in any existing indemnification agreement between any of the Parent Companies or any of the Prize Companies, and any current or former officer or director thereof); provided, that, in the event any claim or claims are asserted or made within such six-year period, all rights to indemnification in respect of any such claim or claims shall continue until final disposition of any and all such claims. (b) From and after the Effective Time, Parent shall, for a period of six years after the Effective Time, indemnify, defend and hold harmless each person who is now, or has been at any time prior to the date of this Agreement or who becomes prior to the Effective Time, an officer, director, employee, controlling stockholder or agent of any of the Parent Companies or any of the Prize Companies (collectively, the "INDEMNIFIED PARTIES") against all losses, expenses (including attorneys' fees), claims, damages, liabilities and amounts that are paid in settlement with the approval of the indemnifying party (which approval shall not be unreasonably withheld) of, or otherwise in connection with, any threatened or actual claim, action, suit, proceeding or investigation (a "CLAIM"), based in whole or in part on or arising in whole or in part out of the fact that the Indemnified Party (or the person controlled by the Indemnified Party) is or was a director, officer, employee, controlling stockholder or agent (including a trustee or fiduciary of any Parent Employee Benefit Plan) and pertaining to any matter existing or arising out of actions or omissions occurring at or prior to the Effective Time (including any Claim arising out of this Agreement or any of the transactions contemplated hereby), whether asserted or claimed prior to, at or after the Effective Time, in each case to the fullest extent permitted under Delaware law, and shall pay any expenses, as incurred, in advance of the final disposition of any such action or proceeding to each Indemnified Party to the fullest extent permitted under Delaware law. In -62- 69 determining whether an Indemnified Party is entitled to indemnification under this Section 5.15, if requested by such Indemnified Party, such determination shall be made by special, independent counsel selected by Parent and approved by the Indemnified Party (which approval shall not be unreasonably withheld), and who has not otherwise performed services for Parent or any of its Affiliates within the last three years (other than in connection with such matters). Without limiting the foregoing, in the event any such claim, action, suit, proceeding or investigation is brought against any Indemnified Party or Parties (whether arising before or after the Effective Time): (i) such Indemnified Party or Parties may retain Parent's regularly engaged independent legal counsel or counsel satisfactory to them and reasonably satisfactory to Parent, and Parent shall pay all reasonable fees and expenses of such counsel for the Indemnified Party or Parties as promptly as statements therefor are received; and (ii) Parent will use all reasonable best efforts to assist in the vigorous defense of any such matter, provided that Parent shall not be liable for any settlement effected without its prior written consent, which consent shall not unreasonably be withheld. In the event of any Claim, any Indemnified Party wishing to claim indemnification will promptly notify Parent thereof (provided, that failure to so notify Parent will not affect the obligations of Parent except to the extent that Parent shall have been prejudiced as a result of such failure) and shall deliver to Parent the undertaking contemplated by Section 145(e) of the DGCL, but without any requirement for the posting of a bond. Without limiting the foregoing, in the event any such Claim is brought against any of the Indemnified Parties, such Indemnified Party or Parties may retain only one law firm (plus one local counsel, if necessary) to represent them with respect to each such matter unless the use of counsel chosen to represent the Indemnified Parties would present such counsel with a conflict of interest, or the representation of all of the Indemnified Parties by the same counsel would be inappropriate due to actual or potential differing interests between them, in which case such additional counsel as may be required (as shall be reasonably determined by the Indemnified Parties and Parent) may be retained by the Indemnified Parties at the cost and expense of Parent and Parent shall pay all reasonable fees and expenses of such counsel for such Indemnified Parties. Parent shall use such counsel for such Indemnified Parties. Parent shall use all reasonable best efforts to assist in the vigorous defense of any such Claim; provided, that Parent shall not be liable for any settlement effected without its written consent, which consent, however, shall not be unreasonably withheld. Notwithstanding the foregoing, nothing contained in this Section 5.15 shall be deemed to grant any right to any Indemnified Party which is not permitted to be granted to an officer, director, employee, controlling stockholder or agent of Parent under Delaware law, assuming for such purposes that Parent's certificate of incorporation and bylaws provide for the maximum indemnification permitted by law. (c) From and after the Effective Time, Parent shall cause to be maintained in effect for not less than six years from the Effective Time the current policies of the directors' and officers' liability insurance maintained by Parent; provided, that (i) Parent may substitute therefor policies of at least the same coverage containing terms and conditions which are no less advantageous; (ii) such substitution shall not result in gaps or lapses in coverage with respect to matters occurring prior to the Effective Time; and (iii) Parent shall not be required to pay an annual premium in excess of 200% of the last annual premium paid by Parent prior to the date -63- 70 hereof and if Parent is unable to obtain the insurance required by this Section 15(c) it shall obtain as much comparable insurance as possible for an annual premium equal to such maximum amount. (d) Following the Merger, if Parent or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any Person or Persons, then, and in each such case, proper provision shall be made so that the successors and assigns of Parent and any of their successors and assigns, assume the obligations of the Parties and Parent set forth in this Section 5.15. (e) This Section 5.15 shall survive the consummation of the Merger at the Effective Time, is intended to benefit Parent and the Indemnified Parties (each of whom may enforce the provisions of this Section 5.15) and shall be binding on the successors and assigns of Parent. 5.16 SEVERANCE PLAN. After the Closing, Parent shall take such action as may be necessary to promptly pay the severance payments due under Parent's Severance Plan, a copy of which is attached as EXHIBIT 5.16. The provisions of this Section 5.16 are intended to be for the benefit of, and shall be enforceable by, the Parties and each person entitled to receive a severance payment pursuant to the terms of Parent's Benefit Severance Plan. 5.17 AMENDMENT OF PARENT CERTIFICATE OF INCORPORATION.

Prior to the Closing, Parent shall take all such actions as may be required to authorize for issuance the Parent Preferred Stock, including approval by the board of directors of Parent of the Parent Preferred Stock Designation in substantially the form of EXHIBIT 5.18 and the filing thereof in accordance with the DGCL. 5.19 JOINT PARTICIPATION AGREEMENT. At the Closing, Prize shall assign to Parent all of the rights, and Parent shall assume all of the obligations, of Prize under the Joint Participation Agreement. 5.20 VOTING AND SHAREHOLDERS AGREEMENT. At the Closing, the Prize Voting and Shareholders Agreement shall be terminated and Parent shall execute an agreement having substantially the same terms and conditions as the Prize Voting and Shareholders Agreement in effect immediately prior to the Effective Time with the holders of shares of the Prize Common Stock and the Prize Preferred Stock which are being converted into shares of Parent Common -64- 71 Stock and Parent Preferred Stock, respectively, in the Merger, except revised to reflect that the IPO (as defined in the Prize Voting and Shareholders Agreement) has already occurred. 5.21 BYLAWS. At the Closing, Parent shall adopt a new set of bylaws which are substantially the same as the bylaws of Prize as in effect immediately prior to the Effective Time. 5.22 PIONEER VOTING AGREEMENT.
