In line with our recent discussion and verbal agreement, the original engagement
agreement between Aztec Manufacturing Co. ("AZZ") and RCG Capital Markets Group,
Inc., ("RCG") dated February 7, 2000 shall be amended to reflect the following
changes:

Referencing paragraph (c) of the Financial Relations Compensation Attachment,
the option exercise price shall be adjusted from $10.13 to $16.25 for those
particular vesting elements and related percentages which occur by securing
research and the second media events as described in that attachment.
Notwithstanding the above, it is agreed that the option exercise price shall
remain at the $10.13 upon securing the first media vesting event. Furthermore,
the option exercise price for the vesting event which occurs upon obtaining a
12.5 P/E ratio, shall be adjusted to become the closing stock price of AZZ
common stock on the 45/th/ consecutive calendar day when achievement has been
obtained for that vesting element. All other option elements vested to date
shall remain as per the terms and conditions of the original attachment.

In addition, by execution of this amendment, both parties acknowledge and agree
that the July 7, 2000 termination letter tendered by AZZ is hereby withdrawn by
the Company.

All other terms, provisions and conditions of the original engagement agreement
shall remain in effect and shall continue to govern the on-going consulting
relationship between RCG and AZZ.

Sincerely,

/s/ A. Max Ramras
