By so doing, you are designating [INSERT YOUR NAME] to act as your authorized agent to make changes to your Yahoo account. You are liable to Yahoo for any actions taken in or changes to your account made using your account information.

    1. No Guaranteed Access to Yahoo APIs. Yahoo may suspend or terminate your access to the Yahoo APIs, or modify any of the Yahoo API Specifications or methods of accessing the Yahoo APIs, for any or no reason at any time without notice in Yahoo’s sole discretion. You acknowledge that you are solely responsible for all necessary data backup and for ensuring that, if you are managing and accessing a Yahoo commercial account on behalf of an Account Owner, you can manage the applicable Yahoo commercial account without access to the Yahoo APIs. This Agreement does not create any right to rely upon the continued availability of and/or access to the Yahoo APIs and/or the Yahoo API Specifications. You expressly waive any right to assert any estoppel claim, contract claim or any other legal claim relating to the availability of and/or access to the Yahoo APIs and/or the Yahoo API Specifications. Yahoo may, in its sole discretion, cease providing the current version of any Yahoo API, at which point the current version of the applicable Yahoo API will be deprecated (the “Deprecated Version”). Yahoo will attempt to issue an announcement if the current version of a Yahoo API will be deprecated. For a short period of time after such announcement (the “Deprecation Period”), Yahoo may use commercially reasonable efforts to continue to operate the Deprecated Version and to respond to problems with the Deprecated Version deemed by Yahoo to be critical, but unless otherwise announced by Yahoo, no new features will be added to the Deprecated Version during the Deprecation Period.
    2. Yahoo Monitoring. Yahoo has the right (but not the obligation) to monitor any Yahoo API activity for any lawful purpose, including to ensure compliance with this Agreement and/or to improve Yahoo’s products and services. You will not interfere with or attempt to interfere with such monitoring or otherwise obscure from Yahoo your Yahoo API activity. Yahoo may use any technical means to overcome such interference.
    3. Usage and Quotas. Yahoo may, at any time and in its sole discretion, set a quota on your usage of the Yahoo APIs or on the amount of data you can transfer using the Yahoo APIs. You will not exceed any such quotas, or take any action designed to or that has the effect of, increasing or avoiding such usage quotas. Yahoo may also impose limits on certain features and services or restrict your access to parts or all of the Yahoo APIs or Yahoo websites without notice or liability.
    4. Technical Support and Training. In its sole discretion, Yahoo may elect to provide you with technical support for the Yahoo APIs and/or Yahoo API Specifications, and may terminate or modify such support at any time without notice or liability to you. You agree to ensure that any of your personnel who market the Yahoo API Client will become and remain knowledgeable about the Yahoo APIs and the Yahoo API Client.
    5. Publicity. Yahoo may use your name and/or logo in presentations, marketing materials, customer lists, financial reports, website listings of customers, research and marketing case studies and other promotional activities. You will not issue a press release, blog post, public statement, or make any other public announcement regarding the existence, subject matter or terms of this Agreement without Yahoo’s prior express written consent as to the issuance and substance of such release or announcement.
    6. Data. You hereby acknowledge that Yahoo has the right to use and disclose data derived from your use of the Yahoo APIs: (i) as part of Yahoo’s business operations, to use and disclose aggregate statistics obtained and/or derived in connection with your use of the Yahoo APIs in a manner that prevents individual identification of you or your information (or the Account Owner’s, as applicable); (ii) to operate, manage, test, maintain and enhance the Yahoo APIs and other Yahoo products, programs and/or services; (iii) to protect the Yahoo APIs from what, in Yahoo’s reasonable determination, is a threat to the Yahoo APIs or other Yahoo products, programs and/or services; and/or (iv) if required by court order or law or required or requested by any governmental agency.
    7. Competing Applications. Notwithstanding anything to the contrary in this Agreement, Yahoo has the right to develop, create, obtain, modify, transfer, provide and/or distribute, whether privately, commercially, or otherwise, any and all applications (including third-party applications) in connection with Yahoo’s commercial programs and/or the Yahoo APIs (“Competing Applications”), regardless of the means, methods, applications, materials or processes employed by Yahoo, and regardless of whether such Competing Applications include some or all the functionality of the Yahoo API Client or the Yahoo APIs. Yahoo and its Affiliates will not be subject to, nor liable for, any claims in connection therewith.
  5. General Terms and Conditions.
    1. Termination. Any licenses expressly granted in this Agreement will terminate automatically without notice if you fail to comply with any provision of this Agreement. Yahoo reserves the right to terminate this Agreement or discontinue the Yahoo APIs or any portion or feature thereof (including the Yahoo API Specifications) for any or no reason and at any time in its sole discretion without incurring any liability. You may terminate this Agreement by sending written notice of your desire to terminate to ews-info@yahooinc.com (or such other email address as may be provided by Yahoo from time to time).

    2. Confidentiality. You will not disclose Yahoo Confidential Information to any third party without Yahoo’s express prior written consent, provided, however that you may disclose Yahoo Confidential Information only to your employees, representatives and agents who have a reasonable need to know such information and who are bound to keep such information confidential in a manner consistent with this Agreement. “Yahoo Confidential Information” means any information disclosed to you by Yahoo, either directly or indirectly, in writing, orally, or by inspection of tangible objects, including (a) all Yahoo technology, programming, software specifications, materials, guidelines and documentation relating to the Yahoo APIs; (b) the Yahoo API Specifications; and (c) any other information designated by Yahoo as “Confidential” or “Proprietary” or a similar designation, or any other information which should reasonably be understood to be confidential or proprietary to Yahoo.

If required by law to disclose Yahoo Confidential Information, you may do so provided that: (i) you give us prompt written notice of such requirement prior to such disclosure; (ii) at Yahoo’s request, you assist us in obtaining an order protecting Yahoo Confidential Information from public disclosure; and (iii) any such disclosure is limited to the minimum extent necessary to comply with the legal requirement. All Yahoo Confidential Information will remain Yahoo’s property, and all documents, electronic media, and other items containing or relating to any Yahoo Confidential Information must be delivered to Yahoo, destroyed, or uninstalled immediately upon Yahoo’s request, or upon termination of this Agreement.
    3. Indemnification.

      THE YAHOO APIS, YAHOO API CREDENTIALS AND YAHOO API SPECIFICATIONS ARE MADE AVAILABLE PRIMARILY AS A CONVENIENCE TO YOU AND, AS SUCH, YOU AGREE THAT THIS AGREEMENT REPRESENTS A FAIR ALLOCATION OF RISK BETWEEN THE PARTIES.
    5. Account Owner Disputes. If you are managing and accessing a Yahoo commercial account on behalf of an Account Owner, and such Account Owner claims that (i) you are not its authorized agent and it is not legally bound to Yahoo and/or its Affiliates for charges to its commercial account made as a result of your actions; or (ii) it has not expressly authorized changes made by you to its commercial account, you will be liable (jointly and severally with the Account Owner) for all charges resulting from changes made by you to the Account Owner’s commercial account.
    6. Miscellaneous. This Agreement will be governed by the laws of the State of California, without regard to its conflict of laws rules or principles. The jurisdiction and venue for all disputes hereunder will be the State of California, County of Los Angeles or Santa Clara, and you and Yahoo consent to personal jurisdiction in those courts. You represent, warrant and covenant that you are a business, not a consumer, and have the rights, authority, and any required permission and consent to enter into this Agreement. Any claim against Yahoo and/or its Affiliates will be adjudicated on an individual basis and will not be consolidated in any proceeding with any claim or controversy of any other party. This Agreement represents the entire understanding between the parties and supersedes all prior agreements, oral or written, relating to the subject matter hereof. Yahoo may provide notices to you, at Yahoo’s option, by email to the email address provided by you to Yahoo, by mail to the postal address provided by you to Yahoo, or by posting on any Yahoo website. It is your responsibility to ensure that your email address and any other contact information you provide to Yahoo is updated and correct.

You and Yahoo are independent contractors and nothing in this Agreement will give you the right, power or authority to create any obligation or responsibility on behalf of Yahoo. Except as otherwise set forth in this Agreement, neither you nor Yahoo will have any right, power, or authority to create any obligation or responsibility on behalf of the other and this Agreement is not intended to benefit, nor will it be deemed to give rise to any rights in, any third party. Notwithstanding the foregoing, you acknowledge and agree that the Yahoo Affiliates will be third-party beneficiaries to this Agreement and will be entitled to directly enforce, and rely upon, any provision in this Agreement which confers a benefit on, or rights in favor of, them. You may not assign, sublicense, or transfer this Agreement or any right or duty under this Agreement. Any assignment, transfer, or attempted assignment or transfer in violation of this Section will be void and of no force or effect. Yahoo and its subsequent assignees may assign, delegate, sublicense, or otherwise transfer from time to time this Agreement, or the rights or obligations hereunder, in whole or in part, to any person or entity, such as to Yahoo Affiliates. No failure or delay on the part of Yahoo in exercising any right, power or remedy under this Agreement will operate as a waiver, nor will any single or partial exercise of any such right, power or remedy preclude any other or further exercise or the exercise of any other right, power or remedy. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction will, as to such jurisdiction, be ineffective only to the minimum extent necessary without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provisions in any other jurisdiction. Yahoo may modify this Agreement at any time by posting such modification on the applicable Yahoo website or by notifying you by email and such revised Agreement will supersede and replace the earlier version. If you do not agree to such modification, your sole remedy is to terminate this Agreement upon written notice to Yahoo. Your continued use of any portion of the Yahoo APIs shall be deemed to be acceptance by you of the modified Agreement. As used in this Agreement, the word “including” is a term of enlargement meaning “including without limitation” and does not denote exclusivity. The section headings and subheadings contained in this Agreement are included for convenience only, and will not limit or otherwise affect this Agreement.
