PART II

         If the subject report could not be filed without unreasonable effort or
expense  and  the  registrant  seeks  relief  pursuant  to Rule  12b-25(b),  the
following should be completed. (Check box if appropriate.)

      |(a)   The reasons described in reasonable detail in Part III of this form
      |      could not be eliminated without unreasonable effort or expense;
      |
      |(b)   The  subject  quarterly  report on Form  10-QSB will be filed on or
  |X| |      before the fifth  calendar day following  the  prescribed  due
      |      date; and

      |(c)   The  accountant's  statement  or  other  exhibit  required  by Rule
      |      12b-25(c) has been attached if applicable.

PART III

         State below in reasonable  detail the reasons why Form 10-QSB could not
be filed within the prescribed period.

       We were unable to file our  Quarterly  Report on Form  10-QSB  within the
prescribed time period without unreasonable effort or expense because we had not
yet completed the footnotes to the financial  statements required to be included
in our Quarterly  Report on Form 10-QSB,  which  footnotes  relate to our recent
sale of Front  Porch  Digital,  Inc.  and the  repayment  of a  majority  of our
long-term debt using the proceeds of such sale.

       As a result of the foregoing, our Quarterly Report on Form 10-QSB for the
quarter ended June 30, 2006 will be filed on or before August 18, 2006, which is
within the extension period provided under Rule 12b-25.

PART IV

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

                         -------------------------------------------------

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

                           Yes |_|                   No |X|

       On April 13, 2006,  as filed with the  Commission on April 17, 2006,  the
Registrant filed a Current Report on Form 8-K relating to its acquisition of all
of the  outstanding  capital  stock of Network  System  Technologies,  Inc.  The
Registrant  has not yet filed the  audited  financial  statements  and pro forma
financial information required by such filing.



         (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?  If so,
                  attach  an  explanation  of  the  anticipated   change,   both
                  narratively and quantitatively, and, if appropriate, state the
                  reasons why a  reasonable  estimate  of the results  cannot be
                  made.

                           Yes |X|                   No |_|


       During the  quarter  ended June 30,  2006,  we  acquired  Network  System
Technologies,  Inc.,  an  Illinois  corporation  ("NST").  As a  result  of this
acquisition, we anticipate a significant change in our total revenue and results
of operations for the quarter ended June 30, 2006.

       Primarily as a result of the  additional  revenues  from the inclusion of
NST, our total revenue from  continuing  operations for the  three-months  ended
June 30, 2006  increased  $4.6 million,  or 34%, to $18.1 million as compared to
total  revenue of $13.5  million for the three months ended June 30, 2005.  This
was  offset  by a  reduction  in sales  of $4.1  million  from our  wholly-owned
subsidiaries,  ManagedStorage International, Inc., ("MSI"), Incentra of CA, Inc.
("Incentra of CA") and PWI Technologies, Inc. ("PWI").

       Primarily  as a result  of the  adoption  of a new  accounting  standard,
during the three months ended June 30, 2006, we incurred an operating  loss from
continuing  operations of $2.7 million as compared to a loss from  operations of
$1.4 million for the three months ended June 30, 2005. This increase in our loss
from  continuing  operations was due to the adoption of SFAS 123R accounting for
additional non-cash compensation expense of $0.4 million, decreased contribution
from  PWI,  MSI and  Incentra  of CA,  Inc.  and an  increase  in sales  related
headcount in the various regions.

       Primarily as a result of the  additional  revenues  from the inclusion of
NST, our total revenue from continuing  operations for the six months ended June
30, 2006  increased  approximately  $9.7  million,  or 58%, to $26.5  million as
compared to total  revenue of $16.7  million  for the six months  ended June 30,
2005. This increase was attributable to the additional  revenues of $8.7 million
resulting from the inclusion of NST for the 2006 period and $1.7 million for the
inclusion of PWI for the 2006 period, offset by a reduction in sales from MSI of
$0.3 million.

       Primarily  as a result  of the  adoption  of a new  accounting  standard,
during the six months  ended June 30, 2006,  we incurred an operating  loss from
continuing  operations of $5.3 million as compared to a loss from  operations of
$3.2 million for the six months ended June 30, 2005.  This  increase in our loss
from  continuing  operations was due to the adoption of SFAS 123R accounting for
additional   non  cash   compensation   expenses  of  $0.7  million,   decreased
contribution  from  PWI,  MSI  and  Incentra  of CA,  Inc.  and an  increase  in
sales-related headcount in the various regions.
