assigns, and no other party shall be a beneficiary hereunder.

               6.3 Attorneys' Fees. In the event a suit, action, arbitration, or
other proceeding of any nature whatsoever, including, without limitation, any
proceeding under the U.S. Bankruptcy Code, is instituted, or the services of an
attorney are retained, to interpret or enforce any provision of this Assignment
or with respect to any dispute relating to this Assignment, the prevailing party
shall be entitled to recover from the losing party its reasonable attorneys',
paralegals', accountants', and other experts' fees and all other fees, costs,

In the event of suit, action, arbitration, or other proceeding, the amount
thereof shall be determined by the judge or arbitrator, shall include fees and
expenses incurred on any appeal or review, and shall be in addition to all other
amounts provided by law. As used herein, the term "attorneys' fees" means
attorneys' fees whether or not litigation ensues and if litigation ensues
whether incurred at trial, on appeal, on discretionary review or otherwise.

               6.4 Severability. The invalidity, illegality or unenforceability
of any provision of this Assignment shall not affect the enforceability of any
other provision of this Assignment, all of which shall remain in full force and
effect.

               6.5 Non-Waiver. No delay or failure by any party to exercise any
right hereunder, and no partial or single exercise of any such right, shall
constitute a waiver of that or any other right, unless otherwise expressly
provided herein.

accordance with laws of the State of Arizona.

               6.7 Counterparts. This Assignment may be executed by any number
