                                    PART III
                                    NARRATIVE

     The  Board  of  Directors  of  The  Management  Network  Group,  Inc.  (the
"Company")  has  appointed  a  Special  Committee  to  conduct  a review  of the
Company's  historical  practices



regarding its stock option  programs and related  accounting for the period from
1999 through 2005.  Following the Special  Committee's  review,  the Company may
need  to  correct  its  historical   determinations   of  non-cash   stock-based
compensation  expense.  If these corrections are material,  the Company would be
required  to  restate  its  financial  statements.  Although  the  impact on the
Company's historical financial statements is not yet known, the Company does not
expect the review to result in changes to its historical  revenues or non-option
related  operating  expenses.  In light of the  Special  Committee  review,  the
Company will not be in a position to file its quarterly  report on Form 10-Q for
the thirteen  week period ended  September 30, 2006 by the November 14, 2006 due
date and does not  anticipate  it will be in a  position  to file the Form  10-Q
within the five day extension period under Rule 12b-25.


                                     PART IV
                                OTHER INFORMATION

     (1) Name and  telephone  number  of  person  to  contact  in regard to this
notification.

                   Hunter Wiggins       312       876-8992
                -------------------- --------- --------------

     (2) Have all other periodic  reports  required under Section 13 or 15(d) or
the Securities  Exchange Act of 1934 or Section 30 of the Investment Company Act
of 1940  during the  preceding  12 months or for such  shorter  period  that the
registrant was required to file such report(s) been filed?  If the answer is no,
identify report(s).                                                [X]Yes [ ] No

     (3) Is it anticipated that any significant  change in results of operations
from the corresponding  period for the last fiscal year will be reflected by the
earnings  statements  to be included in the subject  report or portion  thereof?
                                                                   [X]Yes [ ] No

     The review of our stock option  programs and related  accounting  described
     under Part III above has not been completed.  Therefore, the Company is not
     able  to  provide  full  financial  results  for  the  thirteen  weeks  and
     thirty-nine  weeks ended  September  30, 2006.  On November  13, 2006,  the
     Company  issued a news release  announcing  revenues for the third  quarter
     ended September 30, 2006. In that release,  the Company noted that revenues
     increased 7.9% to $8.7 million for the thirteen  weeks ended  September 30,
     2006 and increased  5.2% to $25.4 million for the  thirty-nine  weeks ended
     September 30, 2006  compared to the  corresponding  periods in 2005.  These
     increases in revenue were primarily  attributable to a significant increase
     in the Company's  strategy  consulting  practice,  which  includes  revenue
     generated by the  operations of Adventis  which was acquired in April 2006,
     largely offset by a decrease in management consulting revenue primarily due
     to the  cancellation  of a  long-running  major client project in the first
     quarter of 2006.







     THE  MANAGEMENT  NETWORK  GROUP,  INC. has caused this  notification  to be
