NETWORK  INSTALLATION  CHAIRMAN  ADDRESSES  SHAREHOLDERS


Irvine,  CA  -  May  13,  2004  PR  Newswire  /  Network Installation Corp. (OTC
Bulletin  Board:  NWIS  -  News)  released  today  the  following  letter  to
shareholders:

Dear  Network  Installation  Shareholders:

     As  you  may  be aware, we have recently experienced some volatility in the
trading  of our shares and I wanted to share my thoughts with you. Over the past
several  weeks,  our  markets have been riled given the recent events in Iraq, a
surge  in  oil  prices and speculation of Fed rate increases within the next few
months.  Despite the fact that we continue to report positive news regarding the
state  of our business, there has been recent acute downward pressure on Network
Installation  shares.

     After  speaking with a number of stock market investors, brokers and others
within  the investment community regarding these events, I believe the consensus
to  be that many investors are currently acting in one of two capacities; taking
profits  in  stocks  which  have  performed  well  to offset losses elsewhere or
liquidating  their  holdings,  converting  to  cash  and  waiting for an optimum
re-entry  point.

Fundamentally,  things  have  never been better for Network Installation. Within
two  weeks, we will be reporting our financials for the first quarter of 2004. I
believe we are on target to meet our business plan goals this year which provide
that  we  continue  with  our  expansion by opening additional sales and service
locations and aggressively pursue another acquisition. It is my belief that when
the market ultimately settles, the trading in our shares will once again be more
reflective  of  the  Company's performance, not the macro events surrounding us.

     We  appreciate  your  support  and  look  forward  to  continuing  with our
progress.


Kindest  Regards,
Michael  Novielli
Chairman
Network  Installation  Corp.
