relationship between them.

     C.   In connection with the termination of the Employment Agreement and the
employment relationship, FirstWorld and Jenkins desire to release each other
from any and all obligations or legal right either may owe to the other, except

part of any wrongdoing or actual liability owed to the other.

     E.   Except as specifically provided below, it is intended that this

                                   AGREEMENT

     1.   Resignation. Jenkins hereby resigns his employment with FirstWorld,
          -----------

     2.   Consideration. In consideration for Jenkins' resignation of
          -------------
employment, position as an officer, and any related positions, the
confidentiality provisions, the releases and other agreements set forth in this
Agreement, FirstWorld agrees as follows:

          To pay Jenkins the following:

          (a)  The sum of $42,499.98, less applicable taxes and other
               withholdings, as Severance Pay under the Employment Agreement
               (which represents the gross amount of base salary through October
               31, 2000). Payments will be made through October 31, 2000 in
               equal installments in accordance with the FirstWorld's regularly
               scheduled payroll dates for exempt employees.

          (b)  FirstWorld will agree to pay to Jenkins 80% of the COBRA premium
               required for continuance of coverage under FirstWorld's Medical,
               Dental and Vision plans from September 1, 2000 through the
               earlier of October 31, 2000 or at the time Jenkins withdraws from
               COBRA coverage under those plans, less required withholdings.
               Payments will be made through October 31, 2000 in equal
               installments in accordance with FirstWorld's regularly scheduled
               payroll dates for exempt employees. It is Jenkins' responsibility
               to properly and timely elect COBRA coverage, if desired, and to
               pay these amounts to the plans under the COBRA procedures of
               those plans.

          (c)  Solely for the purpose of determining vesting under FirstWorld's
               stock option plans, Jenkins' termination date will be November 9,
               2000. Employee shall be entitled to exercise his vested stock
               options on or prior to December 9, 2000 under his Employee Stock
               Option Agreements dated April 15, 1999, December 31, 1999 and
               March 6, 2000, and each such employee stock option agreement
               hereby is deemed amended to reflect such change. Jenkins
               understands that this extension may adversely affect his tax
               consequences under such options. Jenkins shall have no rights as
               to options not vested on or before November 9, 2000, and no
               rights as to vested options not exercised toon or before December
               9, 2000.

               normal and customary deductions for income, employment and other
               tax withholding.

          (b)  FirstWorld will permit Jenkins to continue participation in
               FirstWorld's Medical, Dental and Vision benefit plans at Jenkins'
               present level through and including August 31, 2000, at which
               time all such benefits shall be terminated. Jenkins shall retain
               any rights to continuation coverage under such Plans as he and
               his dependents may have under COBRA. FirstWorld agrees to pay to
               Jenkins 80% of the COBRA premium pursuant to the
