ADVANCED   COMMUNICATIONS   TECHNOLOGIES   INC.  -v-   ADVANCED   COMMUNICATIONS
TECHNOLOGIES  (AUSTRALIA)  PTY  LTD  (ADMINISTRATOR  APPOINTED)  (RECEIVERS  AND
MANAGERS APPOINTED)

     As you are aware,  we act on behalf of Mr David Lockwood and Mr Ken Sellers
who were  appointed  as joint and  several  Receivers  and  Managers of Advanced
Communications   Technologies  (Australia)  Pty  Ltd  (Administrator  Appointed)
(Receives  and  Managers   Appointed)   ("ACTA")  on  29  July  2002  by  Global
Technologies  Communications  Pty Ltd  ("Global")  pursuant  to the  terms  of a
registered Debenture Charge granted by ACTA to Global on 21 December 2001.

     We  refer  to the  stock  purchase  agreement  between  ACTA  and  Advanced
Communications  Technologies  Inc  ("ACTUS")  dated 5  April  2000  ("the  stock
purchase agreement") pursuant to which ACTUS agreed to acquire 20% of the common
stock of ACTA for  payment  of the  Purchase  Price of  US$7.5M on the terms and
conditions  contained  in the stock  purchase  agreement.  WE also  refer to the
affidavits  sworn by Steven Black on 24 May 2002 and by David Lockwood on 10 and
17 October  2002,  which have been filed in the  Supreme  Court of  Victoria  in
proceeding no 4201 of 2002.

     It is clear from the affidavit material filed in that proceeding that ACTUS
is insolvent.  That  affidavit  material is  uncontested  and ACTUS'  insolvency
remains undisputed.

     As a result,  ACTUS has  demonstrated  that it is  unable  to  perform  its
obligations  under the stock purchase  agreement and  accordingly has repudiated
that agreement.

     We are instructed by our clients to accept ACTUS'  repudiation of the stock
purchase  agreement  and we  hereby  give  Notice  of  Termination  of the stock
purchase agreement, with immediate effect.

     As a result of the termination of the stock purchase agreement,  all of the
rights granted by ACTA to ACTUS under that agreement are also  terminated,  with
immediate effect.

<PAGE>

     This letter,  and the termination of the stock purchase  agreement effected
by this letter,  are without prejudice to any other rights and remedies of ACTA,
whether under the stock purchase agreement or otherwise.

Yours faithfully,

ANDREW CHAMBERS
