- ----------
(1)   EBITDA is defined as earnings before interest,  income taxes, depreciation
      and  amortization.  EBITDA,  a  measure  used  by  management  to  measure
      liquidity  and  performance,  is  reconciled  to net earnings and net cash
      provided by (used in) operating  activities in the  following  table.  The
      Company's management believes EBITDA is useful to the investors because it
      is frequently used by securities analysts,  investors and other interested
      parties in the  evaluation of companies in our  industry.  EBITDA is not a
      recognized term under generally accepted  accounting  principles  ("GAAP")
      and does not purport to be an  alternative to net earnings as an indicator
      of operating  performance  or to net cash  provided by (used in) operating
      activities  as a measure  of  liquidity.  Because  not all  companies  use
      identical calculations,  this presentation of EBITDA may not be comparable
      to other  similarly  titled  measures  of other  companies.  Additionally,
      EBITDA is not intended to be a measure of free cash flow for  management's
      discretionary  use, as it does not consider certain cash requirements such
      as interest  payments,  tax payments and debt  service  requirements.  The
      amounts  shown for EBITDA as  presented  herein  differ  from the  amounts
      calculated  under the  definition  of EBITDA  used in the  Company's  debt
      instruments.   The  definition  of  EBITDA  used  in  the  Company's  debt
      instruments is further  adjusted for certain cash and non-cash charges and
      is used to determine compliance with financial covenants and the Company's
      ability to engage in certain activities such as incurring  additional debt
      and making certain payments.

      The results  for the three  months  ended  September  30, 2006  include an
increase  in sales of $27.6  million or 17.6% as  compared  to the three  months
ended  September 30, 2005. New machine sales were $74.5 million,  an increase of
$30.0 million or 67.3% from $44.5  million for the three months ended  September
30,  2005,  and  aftermarket  parts and  service  sales were $110.5  million,  a
decrease of $2.4 million or 2.1% from $112.9  million for the three months ended
September  30, 2005.  The results for the nine months ended  September  30, 2006
include an increase in sales of $129.5  million or 32.1% as compared to the nine
months ended  September  30, 2005.  New machine  sales were $181.7  million,  an
increase of $54.5 million or 42.9% from $127.2 million for the nine months ended
September 30, 2005, and aftermarket parts and service sales were $350.7 million,
an  increase of $75.0  million or 27.2% from $275.7  million for the nine months
ended  September  30, 2005.  The increase in new machine sales for the three and
nine month  periods ended  September  30, 2006 when  compared to the  comparable
periods in 2005 was due to increased prices and sustained demand for commodities
that are  surface  mined by the  Company's  machines  as a result  of  continued
economic  growth  in the  developing  world and  renewed  economic  strength  in
industrialized  countries.  Aftermarket sales also remain strong as the existing
installed  fleet of  Company  machines  around the world  operates  at very high
utilization levels. The Company achieved operating earnings of $26.5 million for
the three months ended  September 30, 2006 and $74.9 million for the nine months
ended  September  30,  2006.  Operating  earnings  for the three and nine  month
periods ended  September 30, 2006 increased from the comparable  periods in 2005
primarily due to increased gross profit resulting from increased sales volume.

      As of September 30, 2006, the Company's  total backlog was $755.5 million,
$504.3  million of which was expected to be  recognized  within twelve months of
such date. This represents a 14.7% and 22.1% increase from the December 31, 2005
total  backlog of $658.6  million and twelve months  backlog of $413.1  million,
respectively,  and a 28.0% and 46.4%  increase from the September 30, 2005 total
backlog  of  $590.2  million  and  twelve  months  backlog  of  $344.4  million,
respectively.  The increase  from  December 31, 2005 and  September 30, 2005 was
primarily due to an increase in new machine orders, which totaled $120.5 million
during the third  quarter of 2006 and  included  an 8750AC  walking  dragline in
Australia. Inquiries for the Company's machines remain at a high level.

      As  of  September  30,  2006,   the  Company  had  aggregate   outstanding

      On July 20, 2006, Bucyrus announced that it will undertake the third phase
of its multi-phase expansion program at its South Milwaukee facility.  The first
phase of the expansion provides 110,000 square feet of new space for welding and
machining of large  electric  mining  shovel  components  and was  substantially
complete at the end of the third quarter.

      The  second  phase,  announced  on  February  16,  2006,  will  expand the
Company's  new facility  north of Rawson  Avenue to over 350,000  square feet of
welding,  machining  and  outdoor  hard-goods  storage  space.  Construction  is
expected to be  completed  in mid-2007  and is  currently  ahead of the original
schedule.  The aggregate  cost of phase one and two of the expansion  project is
expected to be approximately $54 million.

      The third phase of the expansion project,  which was announced on July 20,
2006, was approved in support of Bucyrus'  ongoing efforts to meet the continued
growth of demand for its machines and their components. Phase three will include
the renovation of manufacturing  buildings and offices at the Company's existing
facilities south of Rawson Avenue in South Milwaukee,  Wisconsin, USA. Its focus
is on modernizing and improving  manufacturing and  administrative  efficiencies
and  includes  renovation  as well as expansion  of existing  buildings  and the
addition  of new  machine  tools.  The steps for  accomplishing  phase three are
scheduled  to  maximize  manufacturing  throughput  during  the  renovation  and
construction processes. Phase three construction is scheduled to be completed by
the fourth quarter of 2007 and is expected to cost approximately $58 million.
