     (a)     Confidential Information of the other party may be used by OSC only
in connection with the Services.

     (b)     OSC agrees to protect the confidentiality of the Confidential

confidence, (ii) independently developed by it, (iii) acquired by it from a

issued administrative or judicial process requesting any portion of the
Confidential Information of the other party, it shall promptly notify the other
party and tender to it defense of such demand. Unless the demand shall have been

to comply with such subpoena or other process to the extent permitted by law. If
requested by the disclosing party, the recipient shall cooperate (at the expense
of the disclosing party) in the defense of a demand.

11.     INDEMNIFICATION

     (a)     Each party (an "Indemnifying Party") shall indemnify and hold the
other party, its employees and agents (each, an "Indemnified Party"), harmless
from and against all claims, demands, loss, damage or expense, including
reasonable attorneys' fees (collectively, "Losses"), to the extent such Losses
are caused by the negligence, willful acts or omissions or breach of this
Agreement of or by the Indemnifying Party and except to the extent such Losses
are caused by the negligent or willful acts or omissions of the Indemnified
Party.

promptly notify the Indemnifying Party in writing of a claim or suit and provide

to indemnify the other under any settlement made without its written consent.

for payment of any and all employment related taxes, insurance and employee
benefits with respect to OSC's personnel.

state and federal courts sitting in Maricopa County, Arizona.

14.     SEVERABILITY

     If any term or provision of this Agreement shall be found by a court of
competent jurisdiction to be invalid, illegal or otherwise unenforceable, the
same shall not effect the other terms or provisions hereof or the whole of this
Agreement, but such term or provision shall be deemed modified to the extent
necessary in the court's opinion to render such term or provision enforceable,
and the rights and obligations of the parties shall be construed and enforced
accordingly, preserving to the fullest permissible extent the intent and
agreements of the parties herein set forth.

15.     NOTICE

     Any notice or other communication given pursuant to this Agreement shall be
