The Parties further agree that, to the extent permitted by applicable law, all federal, state or other Tax Returns shall be filed consistently with this position.

(d) Straddle Period Taxes. For purposes of this Agreement, Taxes shall be allocated between the Pre- and Post-Closing Straddle Periods, in Holding’s reasonable judgment with the consent of the appropriate Hyatt and Classic personnel, which shall not be unreasonably withheld, on the basis of the actual taxable income for each such period, determined by closing the books of the Pre-Spin-off Group at the close of business on the Distribution Date.

References herein to a “Party” (or “Parties”) to this Agreement shall refer to Holding, Hyatt and Classic. Capitalized terms not otherwise defined herein shall have the same meaning ascribed to them in the Tax Separation Agreement (as hereinafter defined).

WHEREAS, prior to June 30, 2004, Holding and its Subsidiaries (including Hyatt and Classic and their respective Subsidiaries, from time to time) joined in filing consolidated federal Tax Returns and certain consolidated, combined or unitary state, local or foreign Tax Returns;

WHEREAS, the Parties entered into a Tax Separation Agreement, dated as of June 30, 2004 (the “Tax Separation Agreement”), to provide for (i) allocations of, and indemnifications against, certain liabilities for Taxes, (ii) the preparation and filing of Tax Returns and the payment of Taxes with respect thereto, (iii) the control of audits and other proceedings with respect to Taxes, and (iv) certain related matters;

WHEREAS, pursuant to that certain Master Distribution Agreement, dated as of June 30, 2004, by and among Holding, Hyatt and Classic, Holding distributed all of the outstanding common stock in each of Classic and Hyatt to its stockholders in transactions intended to qualify for tax-free treatment under Code Section 355 (the “Classic Spin-off” and the “Hyatt Spin-off,” respectively, and collectively, the “Spin-offs”), and consequently, Classic and its Subsidiaries and Hyatt and its Subsidiaries left the Pre-Spin-off Group;

WHEREAS, pursuant to the Tax Separation Agreement, Hyatt had the obligation and the right, with certain limitations, to control audits and other proceedings with respect to Taxes of any affected taxpayer for Pre-Closing Taxable Periods and Straddle Periods;

WHEREAS, since the Spin-Offs each of the Parties has either developed its own internal tax compliance function or has engaged advisors in the preparation and filing of Tax Returns and to represent its interests in Tax audits and administrative, judicial or other proceedings with respect to Taxes; and

WHEREAS, in light of such developments, the Parties wish to amend certain provisions of the Tax Separation Agreement to better align the control of Tax audits and proceedings with the underlying liability for Taxes.

NOW THEREFORE, in consideration of their mutual promises, the Parties hereby agree as follows:

1. Control and Settlement. The Tax Separation Agreement is amended hereby as follows:

a. Section 6(b) of the Tax Separation Agreement is amended and restated in its entirety as follows:

(ii) Subject to Section 6(b)(vi), Hyatt shall have the right and obligation to control, to represent the interests of all affected taxpayers in, and to employ counsel of its choice with respect to any federal income Tax audit or administrative, judicial or other proceeding relating, in whole or in part, to any Pre-Closing Taxable Period or Straddle Period relating to the IRS’s proposal to disallow interest expense claimed by the Pre-Spin-Off Group for the taxable year ended January 31, 2001 for a contingent payment made by HT-Long Beach, Inc. on December 29, 2000.

(iii) Subject to Section 6(b)(vi), Classic shall have the right and obligation to control, to represent the interests of all affected taxpayers in, and to employ counsel of its choice with respect to any federal income Tax audit or administrative, judicial or other proceeding relating, in whole or in part, to any Pre-Closing Taxable Period or Straddle Period relating to proceedings regarding partnerships in which a Classic Member is the tax matters partner, including but not limited to any proposal by the IRS to include continuing care community entrance fee deposits (“Entrance Fees”) in the income of (A) CCW LaJolla, L.L.C. (“LaJolla”) for the taxable years ended January 31, 2003 or LaJolla or Aventura Associates, L.L.C. (“Aventura”) for the taxable years ended December 31, 2003 and December 31, 2004.

Notwithstanding anything to the contrary in this Agreement, Holding shall have the right and obligation to control, to represent the interests of all affected taxpayers in, and to employ counsel of its choice with respect to any Tax audit or administrative, judicial or other proceeding relating, in whole or in part, to any Pre-Closing Taxable Period or Straddle Period corporate income Tax Returns of CC-Lake, Inc.; provided, however, that Holding and Classic agree to use commercially reasonable efforts to obtain an assurance from the IRS

2

that it will hold in abeyance its examination of Entrance Fees related to CC-Lake, Inc. for its taxable years ended December 31, 2003 and June 30, 2004 pending the outcome of the LaJolla and Aventura proceedings.

Notwithstanding the foregoing, no Party shall enter into any settlement that causes another Party to become liable to indemnify the first Party under this Agreement without the written consent of such other Party, which may be granted or withheld in its sole discretion.

b. Section 6(c) of the Tax Separation Agreement is amended and restated in its entirety as follows:

(c) Delivery of Powers of Attorney with Other Documents. Each Party shall execute and deliver to the other Parties, promptly upon request, powers of attorney authorizing the relevant Parties to extend statutes of limitations, receive refunds, negotiate settlements and take such other actions that such Party reasonably considers to be

3

appropriate in exercising its control rights pursuant to Section 6(b), and any other documents reasonably necessary thereto to effect the exercising of such control rights.

2. Limitations. This Agreement is limited by its terms and does not and shall not serve to amend or waive any provisions of the Tax Separation Agreement except as expressly provided for in this Agreement.

This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware without regard to the conflict of law principles thereof, except with respect to matters of law concerning the internal corporate affairs of any corporate entity which is a party to or subject of this Agreement, and as to those matters the law of the jurisdiction under which the respective entity derives its powers shall govern.

5. Counterparts, Headings. This Agreement may be executed in any number of counterparts, each such counterpart being deemed to be an original instrument, and all of such counterparts shall together constitute one and the same instrument.
