     installed or product is shipped, Exodus will invoice the Customer.
     Payments for subsequent billing periods will be issued in advance of the
     provision of service. Invoices are due upon receipt.
3.   Exodus makes no warranty of any kind with respect to services and products
     provided under this Agreement. Exodus DISCLAIMS ALL WARRANTIES, EXPRESS

     SERVICES. In situations involving performance or nonperformance of
     services or products furnished under this Agreement, Customer's sole
     remedy shall be: in the case of products, repair, or return of the
     defective product to Exodus for refund, at the discretion of Exodus. In
     the case of services, refund of a prorata portion of the price paid for
     services which were not provided. Credit will only be issued for periods
     of lost service greater than 24 hours. Nothing on this clause shall
     preclude customer from cancelling service as defined in Section 2 above.
4.   Exodus will not be liable for any damages Customer may suffer arising out
     of acts of God, use, or inability to use, Exodus's Internet services or
     related products unless such damages are caused by an intentional and
     willful act of Exodus. In no event shall Exodus be liable for unauthorized
     access to Customer's transmission facilities or Customer premise
     equipment or for unauthorized access to or alteration, theft or
     destruction of Customer's data files, programs, procedure or information
     through accident, fraudulent means or devices, or any other method.
     Exodus will not be liable for indirect, incidental, special or
     consequential damages or for any lost property or data of Customer.
     Exodus's liability for damages to Customer for any cause whatsoever,
     regardless of form of action, including negligence, shall not exceed an
     amount equal to the price of products and services purchased by Customer
     during the twelve month period preceding the event which caused the
     damages or injury.
5.   Exodus will indemnify and hold Customer harmless against any claims or
     demand by any third party that any hardware or software provided by Exodus

     such indemnity, Customer agrees to indemnify and hold Exodus harmless
     against any claim or demand by any third party due to or arising out of
     the use by Customer of Internet services and related products provided
     hereunder.
6.   Customer is solely responsible for the content of any transmissions by
     Customer and any third party utilizing customer's facilities or Exodus'

     subject to their respective permission and usage policies. Customer agrees
     to comply with all applicable laws with regard to the transmission and use
     of information and content, solicitation of any activity that is
     prohibited by applicable law over Internet. Customer further agrees not to
     use the

     network users, network services or network equipment. Customer shall be
     liable for and shall indemnify and defend EXODUS from and against any
     claims in anyway arising from or related to (i) the alleged infringement of
     patent, trademark, design, copyright or any other intellectual property
     rights in relation to the Customer's use of the services and (ii) Customer
     use or inclusion of any information, photographs, art work or other

     right of publicity, the Communications Decency Act of 1996, obscenity or
     pornography, and the violation of any sales or ordinances or other laws).

     provided under this Agreement, may require registrations and related
     administrative reports which are public in nature. In addition Customer
     agrees Exodus may include its name in directories of Exodus customers.
 8.  Unless otherwise authorized in writing by Exodus and attached as an Addenda
     to this agreement, Customer shall limit access to and use of the Internet
     connection services to its employees solely for Customer's business
     purposes and shall not resell or otherwise generate income by providing
     connectivity to the Internet service to third parties. Customer's right to
     use the Internet services and products provided hereunder is limited to
     Customer and is nontransferable.
 9.  Failure by the Customer to comply with the terms of this agreement will
     result in immediate termination of Exodus Internet services.
10.  Customer agrees not to export or re-export (including by way of electronic
     transmission), directly or indirectly, any software or technical data
     through the Internet services without first obtaining any required export
     license or governmental approval.
11.  This Agreement, together with any Addenda, constitute the entire agreement
     of the parties with respect to the services and products provided hereunder
     and supersede any prior agreements. These terms and conditions shall 
     prevail notwithstanding any different or additional terms and conditions 
     in any forms provided by Customer. No waiver of any rights hereunder shall
     be deemed to be a waiver of the same right on any other occasion. This
     Agreement shall be governed by the laws of the State of California without
     regard to conflicts of law principles.

accepted.
