At any time during or after Employee’s employment with the Company ends, without the prior written consent of the Company, except (i) in the course of carrying out Employee’s duties hereunder or (ii) to the extent required by a court or governmental agency, or by applicable law or under compulsion of legal process, Employee shall not disclose to any third person any information concerning the business of the Company, including, without limitation, any trade secrets, customer lists and details of contracts with or requirements of customers, the identity of any owner of a managed hotel, information relating to any current, past or prospective management agreement or joint venture, information pertaining to business methods, sales plans, design plans and strategies, management organization, computer systems and software, operating policies or manuals, personnel records or information, information relating to current, past or contemplated employee benefits or compensation data or strategies, business, financial, development or marketing plans, or manpower strategies or plans, financial records or other financial, commercial, business or technical information relating to the Company (collectively, “Confidential Information”), unless such Confidential Information has been previously disclosed to the public by the Company or is in the public domain (other than by reason of Employee’s breach of this Section 2). Employee will, prior to making any such disclosure pursuant to subsection (ii), promptly notify the Company of his/her receipt of such process or requirement, consult with the Company on the advisability of taking steps to resist or narrow such request, cooperate with the Company in any attempt that the Company may make to obtain a court order or other reliable assurance that confidential treatment will be accorded to all or designated portions of such information, and not disclose such Confidential Information unless the Company shall have had reasonable opportunity to obtain a court order prohibiting or limiting such disclosure.

3.1 Employee agrees that, both during and after Employee’s employment with the Company, if Employee is uncertain of whether or not information is confidential, Employee will treat that information as Confidential Information until Employee has received written verification from an authorized officer of the Company that the information is not Confidential Information.

4. Intellectual Property and Publicity Rights. Employee acknowledges and agrees that all right, title and interest in and to patents, patent applications, inventions, improvements, discoveries, developments, processes, business methods, technical information, know-how, trade secrets, computer programs, writings, designs, copyrights, maskworks, trademarks, service marks, trade names, trade dress and the like (collectively, “Intellectual Property”), including the right to invoke the benefit of the right of priority provided by any treaty to which the United States is a party, which Employee creates, conceives, develops or obtains, either solely or jointly with others, during Employee’s employment with the Company (a) with the use of the Company’s time, materials, facilities or other resources; or (b) resulting from or suggested by Employee’s work for the Company; or (c) in any way relating to any subject matter relating to the existing or contemplated business, products and services of the Company or the Company’s affiliates, subsidiaries and licensees shall be owned by the Company. Upon request, Employee shall execute all such assignments and other documents and take all such other action as the Company may reasonably request in order to vest in the Company, or its nominee, all of Employee’s right, title, and interest in and to such Intellectual Property. Employee further acknowledges and agrees that the Company shall have the perpetual, worldwide right to use Employee’s name, performance, biography, voice, image, signature and likeness in promotional or any other materials developed by or for the Company during Employee’s employment with the Company. Employee hereby irrevocably and unconditionally waives any and all rights that he/she has or may have in and to the Intellectual Property, including, without limitation, any “moral rights” that he/she has or may have as “author” of the Intellectual Property, and hereby expressly agrees not to make any claim or demand against the Company or any party authorized by the Company to exploit the Intellectual Property.

5. Equitable Relief.

5.1 Employee acknowledges that the restrictions and obligations specified in Sections 1, 2 and 3 hereof are reasonable in view of the nature of the business in which the Company is engaged and Employee’s knowledge of, and responsibilities with respect to, the Company’s business, and that any breach of Sections 1, 2 or 3 hereof may cause the Company irreparable harm for which there is no adequate remedy at law, and as a result of this, the Company will be entitled to the issuance by a court of competent jurisdiction of an injunction, restraining order or other equitable relief in favor of the Company, without the necessity of posting a bond, restraining Employee from committing or continuing to commit any such violation. Any right to obtain an injunction, restraining order or other equitable relief hereunder will not be deemed to be a waiver of any right to assert any other remedy the Company may have at law or in equity, including, without limitation, the right to cancel payments to which Employee is otherwise entitled under Employee’s employment agreement.

5.2 Any proceeding or action seeking equitable relief for violation of Sections 1, 2 and 3 hereof may be commenced in the federal courts in the Southern District of the State of New York, or in the absence of federal jurisdiction in state court in the State of New York. Employee hereby irrevocably and unconditionally submits to the exclusive jurisdiction of such courts and agrees to take any and all future action necessary to submit to the jurisdiction of such courts. Employee irrevocably waives any objection that Employee now has or hereafter may have to the laying of venue of any suit, action or proceeding brought in any such court and further irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. Final judgment against Employee in any such suit will be conclusive and may be enforced in other jurisdictions by suit on the judgment, a certified or true copy of which will be conclusive evidence of the fact and the amount of any liability therein described, or by appropriate proceedings under an applicable treaty or otherwise.

6. Severability. In the event that any provision of this Agreement conflicts with the law under which this Agreement is to be construed, and/or if any such provision is held invalid by a court with jurisdiction over the parties to this Agreement and the subject matter of this agreement, (a) such provision will be deemed to be restated to reflect as nearly as possible the original intentions of the parties to the fullest extent permitted under applicable law, and (b) the remaining terms and provisions of this Agreement will remain in full force and effect.

7. Governing Law. This Agreement shall be construed, governed and enforced according to the laws of the State of New York without regard to its conflicts of laws principles.

8. Amendments and Waivers. No failure to act by the Company will waive any right contained in this Agreement. No provision of this Agreement may be amended or waived, except by a written agreement signed by both Employee and an authorized executive officer of the Company. Any waiver by the Company of strict performance of any provision of this Agreement shall not be a waiver of or prejudice the Company’s right to require strict performance of that same provision or any other provision of the Agreement in the future.

Employee acknowledges that he/she has had a reasonable opportunity to review and consider the terms described above and to consult with an attorney if he/she so chooses prior to signing this Agreement. Fully understanding the above terms, Employee is entering into this letter agreement knowingly and voluntarily.
