                                                           For Immediate release


                CERBCO ANNOUNCES COMPLETION OF SALE OF ASSETS AND
       BUSINESS BY SUBSIDIARY INSITUFORM EAST TO INSITUFORM TECHNOLOGIES

     LANDOVER,  MD,  September 5, 2003 - CERBCO,  Inc.  ("CERBCO")  (OTC:  CERB)
announced that its indirect,  majority owned  subsidiary,  Insituform East, Inc.
("East") (OTC:  INEI) today  completed the sale of  substantially  all of East's
non-real estate assets and on-going business,  including East's Insituform(R)and
NuPipe(R)licenses,  to Insituform Technologies, Inc. ("ITI") of Chesterfield, MO
(Nasdaq National Market: INSU). The purchase price of approximately $5.5 million
was paid in cash to East at the closing,  less a 10% escrow. With the closing of
this sale,  ITI has completed the  acquisition  of the  businesses of all of its
North American Insituform(R)licensees, initially commenced by ITI in 1991.

     Among  other  agreements  under the sale,  East will  formally  change  its
corporate name to "INEI  Corporation"  ("INEI") upon the filing of a Certificate
of  Amendment  with the  Secretary  of State  for the  State of  Delaware.  This
amendment had been  previously  approved by written  consent of the holders of a
majority of the  Corporation's  outstanding  stock.  East will continue to trade
under its previous stock symbol "INEI."

     As previously  announced by East,  following completion of the sale to ITI,
East  intends  to  undertake  consideration,  in due  course,  of  one  or  more
transactions  designed to maximize stockholder value. East currently anticipates
that  such a  transaction  will  likely  take the form of a  dissolution  of the
corporation,   the  liquidation  of  its  remaining  assets,  and  the  ultimate
distribution  to  stockholders  of any assets  remaining  after  satisfaction of
East's  liabilities,  including  personnel  termination and related costs,  sale
transaction  expenses  and final  liquidation  costs.  As East is CERBCO's  sole
operating subsidiary,  in light of both the ITI sale and East's consideration of
its likely  future  course of  action,  CERBCO has  announced  that it  likewise
expects to  undertake  consideration  of one or more  transactions  designed  to
maximize  stockholder  value.  To the  extent  that  East  ultimately  elects to
dissolve,  CERBCO  anticipates  that it is  likely  that it also  will  elect to
dissolve,  liquidate  its  remaining  assets  and,  after  satisfaction  of  its
liabilities,  including  personnel  termination  and related costs,  transaction
expenses  and  final  liquidation  costs,  distribute  to its  stockholders  any
remaining assets.  Any such dissolution and plan of distribution of assets would
be subject to approval by both CERBCO's Board of Directors and its stockholders.
CERBCO  currently  expects that it will determine its future course of action in
time to submit such recommendations as may be necessary for stockholder approval
in time for the next regular annual meeting of stockholders, currently scheduled
for December 18, 2003. Neither CERBCO nor East currently is able to estimate, if
it elects  to  dissolve  and  liquidate,  the  amount of  residual  assets  that
ultimately  will be available  for  distribution  to  stockholders  or the exact
timing of any such  distribution.  However,  under the terms of East's sale,  no
distribution  to  stockholders  may be made by East  until  at  least  one  year
following the closing.

     INEI Corporation,  formerly Insituform East, Inc., anticipates that it will
maintain  its  present  address  and  contact  information  for the  immediately
foreseeable future.

     Statements  in this press release that are not  historical,  as well as its
future plans,  are  forward-looking  statements,  as that term is defined in the
Private  Securities   Litigation  Reform  Act  of  1995.  These  forward-looking
statements  involve known and unknown risks,  uncertainties  and other important
factors  that are  subject to change at any time and from time to time.  Factors
that could cause actual results or developments to differ  materially from those
described  in or  contemplated  or  implied by such  forward-looking  statements
include,  without  limitation,  the risk  that the  assumptions  upon  which the
forward-looking  statements  are based  ultimately  may prove to be incorrect or
incomplete  or the risk that ITI will make  claims  against  the  portion of the
purchase  price  placed  in  escrow  or  otherwise,  as well as other  risks and
uncertainties  that are described in the Company's  filings with the  Securities
and Exchange Commission.

                CERBCO ANNOUNCES COMPLETION OF SALE OF ASSETS AND
       BUSINESS BY SUBSIDIARY INSITUFORM EAST TO INSITUFORM TECHNOLOGIES

     LANDOVER,  MD,  September 5, 2003 - CERBCO,  Inc.  ("CERBCO")  (OTC:  CERB)
announced that its indirect,  majority owned  subsidiary,  Insituform East, Inc.
("East") (OTC:  INEI) today  completed the sale of  substantially  all of East's
non-real estate assets and on-going business,  including East's Insituform(R)and
NuPipe(R)licenses,  to Insituform Technologies, Inc. ("ITI") of Chesterfield, MO
(Nasdaq National Market: INSU). The purchase price of approximately $5.5 million
was paid in cash to East at the closing,  less a 10% escrow. With the closing of
this sale,  ITI has completed the  acquisition  of the  businesses of all of its
North American Insituform(R)licensees, initially commenced by ITI in 1991.

     Among  other  agreements  under the sale,  East will  formally  change  its
corporate name to "INEI  Corporation"  ("INEI") upon the filing of a Certificate
of  Amendment  with the  Secretary  of State  for the  State of  Delaware.  This
amendment had been  previously  approved by written  consent of the holders of a
majority of the  Corporation's  outstanding  stock.  East will continue to trade
under its previous stock symbol "INEI."

     As previously  announced by East,  following completion of the sale to ITI,
East  intends  to  undertake  consideration,  in due  course,  of  one  or  more
transactions  designed to maximize stockholder value. East currently anticipates
that  such a  transaction  will  likely  take the form of a  dissolution  of the
corporation,   the  liquidation  of  its  remaining  assets,  and  the  ultimate
distribution  to  stockholders  of any assets  remaining  after  satisfaction of
East's  liabilities,  including  personnel  termination and related costs,  sale
transaction  expenses  and final  liquidation  costs.  As East is CERBCO's  sole
operating subsidiary,  in light of both the ITI sale and East's consideration of
its likely  future  course of  action,  CERBCO has  announced  that it  likewise
expects to  undertake  consideration  of one or more  transactions  designed  to
maximize  stockholder  value.  To the  extent  that  East  ultimately  elects to
dissolve,  CERBCO  anticipates  that it is  likely  that it also  will  elect to
dissolve,  liquidate  its  remaining  assets  and,  after  satisfaction  of  its
liabilities,  including  personnel  termination  and related costs,  transaction
expenses  and  final  liquidation  costs,  distribute  to its  stockholders  any
remaining assets.  Any such dissolution and plan of distribution of assets would
be subject to approval by both CERBCO's Board of Directors and its stockholders.
CERBCO  currently  expects that it will determine its future course of action in
time to submit such recommendations as may be necessary for stockholder approval
in time for the next regular annual meeting of stockholders, currently scheduled
for December 18, 2003. Neither CERBCO nor East currently is able to estimate, if
it elects  to  dissolve  and  liquidate,  the  amount of  residual  assets  that
ultimately  will be available  for  distribution  to  stockholders  or the exact
timing of any such  distribution.  However,  under the terms of East's sale,  no
distribution  to  stockholders  may be made by East  until  at  least  one  year
following the closing.

maintain  its  present  address  and  contact  information  for the  immediately
foreseeable future.

     Statements  in this press release that are not  historical,  as well as its
