Item 1.01      Entry into a Material Definitive Agreement

     On December 22, 2006, we entered into a Share  Purchase  Agreement with the
shareholders (the "selling shareholders") of Cartesian Limited, a United Kingdom
company ("Cartesian"),  pursuant to which we have agreed to purchase 100% of the
outstanding  stock  of  Cartesian  from  the  selling  shareholders  for a total
expected purchase price of approximately  $4.9 million plus  approximately  $2.4
million for excess working  capital making the total value of the transaction at
closing  approximately  $7.3 million,  plus up to approximately  $7.8 million in
potential future earnout  consideration  based upon the performance of Cartesian
after the closing date.  The  consideration  is expressed and payable in cash in
British  pounds.  The selling  shareholders  will continue to be employed by and
will manage  Cartesian  after the closing  date  pursuant to written  employment
agreements.  The selling  shareholders'  transaction costs will be paid by TMNG.
TMNG will assume all liabilities  (including pension  liabilities) of Cartesian,
subject to certain  tax  indemnities  on the part of the  selling  shareholders.
Additional information with respect to the transaction is contained in the press
release attached as Exhibit 99.1 to this report.

     We expect to close the  transaction in early January 2007.  There can be no
assurance the transaction will close.
