[Letterhead of C2i Solutions, Inc.]

April 30, 1999

Clyde Wooten

Dear Clyde:

This letter is the "Amendment" to your employment letter dated May 30, 1997,
which set forth the basic terms and conditions of your employment with Challenge
2000 International LLC, currently known as C2i Solutions, Inc. as a result of a
name change on September 30, 1997 ("C2i").  Effective as of March 23, 1999, your
employment letter is amended as follows:

          17.  TERMS OF EMPLOYMENT.  If you are terminated for any reason,
               -------------------
          within a period of five years commencing on the date that you sign
          this Agreement, other than cause you will receive two year's salary
          continuation, payable in accordance with C2i's standard payroll
          practices, in lieu of notice. If you are terminated with cause within
          five years of the date that you sign this Agreement, you will receive
          six month's salary continuation, payable in accordance with C2i's
          standard payroll practices, in lieu of notice.

          If you resign you shall not be entitled to salary continuation. Upon
          any termination, or resignation, you shall be entitled to payment for
          accrued vacation and for salary and bonuses accrued for service
          actually rendered prior to the date of such termination.

          For purposes of this Agreement "cause" shall mean (i) a willful
          failure by you to substantially perform your duties, other than a
          failure resulting from your complete or partial incapacity due to
          physical or mental illness or impairment, or (ii) a willful act by you
          which constitutes gross misconduct and which is materially injurious
          to C2i.

          All stock option grants to you of Common Stock of C2i Solutions, Inc.
          will continue to vest with your continued employment. If your
          employment is terminated by C2i during this five year period for any
          reason other than cause you will then have a minimum of 60 days from
          the termination date in which to exercise your options, in accordance
          with the terms of the Option Agreements.

This Amendment dated April 30, 1999, and the employment letter dated May 30 1997
constitute the entire agreement between the parties.  All prior agreements or
understandings, written or oral are superceded.

                                       1
