|   |  | 2.2 Quality of Services and Additional Services. Throughout the Term of
this Agreement, the Services and Inktomi Technology (including, without
limitation, the Inktomi Search Engine) and all related features,
functionality, performance, support and upgrades provided hereunder will
substantially equal, with regard to both scope and quality, to those
Inktomi provides other Inktomi customers. For clarity, the Inktomi
Search Engine used to provide the Services will be substantially the same
search engine as that used by Inktomi to provide similar service to other
Inktomi customers and will include substantially the same features,
database sizes, database freshness, and functionality that are generally
offered by Inktomi to other Inktomi customers, but no less than the
features, database sizes, database freshness, and functionality set forth
on Exhibits A-1 and A-2. Inktomi will make available the latest versions
of the Inktomi Search Engine on the Services at the same time Inktomi
makes such versions available to other Inktomi customers. New Services
and Inktomi Technology that are made generally available by Inktomi to
its customers on a premium or non-premium basis will be offered to
Customer no later than the same time they are offered by Inktomi to other
Inktomi customers. Furthermore, upon request, Customer may request
customized services to be provided by Inktomi which are not otherwise
contemplated or provided for by this Agreement. Such customized services
shall be mutually agreed upon by the parties and shall be set forth in
the parties reasonable discretion, on an additional Exhibit to this
Agreement, which upon execution, shall become binding between the
parties. Such customized services, if provided pursuant to an additional
Exhibit shall be provided in accordance with the rates, charges, terms
and conditions of such Exhibit and the terms of this Agreement.
