Item 1.  Business

(a)  General Development of the Business

Dravo   Corporation   (the  Registrant)   was   incorporated   in
Pennsylvania  in 1936 to consolidate several related corporations
then operating various elements of a business started in 1891  by
F.  R.  Dravo.   Its corporate offices are located  at  3600  One
Oliver  Plaza,  Pittsburgh,  Pennsylvania  15222-2682,  and   its
telephone number is 412-566-3000.  As used herein, the term Dravo
includes   its   consolidated   subsidiaries   unless   otherwise
indicated.   In  December,  1987,  Dravo's  Board  of   Directors
approved a major restructuring program which concentrated Dravo's
future  direction  exclusively  on  opportunities  involving  its
natural resources business.  The plan included the sale or  other
disposition  of the former Engineering and Construction  segment,
as  well as the sale of the former Materials Handling and Systems
segment approved earlier.  All units scheduled for sale were sold
by  the end of 1989.  The remainder of these businesses have been
presented   as    discontinued  operations   in   the   financial
statements.

Late  in 1994, the company sold substantially all the assets  and
certain  liabilities  of  Dravo  Basic  Materials  Company,   its
construction aggregates subsidiary, to Martin Marietta Materials,
Inc.  (Martin Marietta).  As a result, Dravo is now  primarily  a
lime   company  operating  principally  in  the  United   States.
Operations  are  carried on by a wholly-owned  subsidiary,  Dravo
Lime Company (Dravo Lime).  Activities include the production  of
lime  for  utility,  metallurgical, pulp  and  paper,  municipal,
construction   and   miscellaneous   chemical   and    industrial
applications.   Three  major  utility  companies  with  whom  the
company  has  long-term  contracts  -  American  Electric  Power,
Pennsylvania Power Company and Cincinnati Gas & Electric  Company
- - each accounted for more than 10 percent of consolidated revenue
in  1995.  All of the properties on which the company's  reserves
are  located are physically accessible for purposes of mining and
processing limestone into lime.

Dravo Lime, one of the nation's largest lime producers, owns  and
operates  three  integrated lime production  facilities,  two  in
Kentucky  and one in Alabama.  In 1995 the Black River  plant  in
Butler,  Kentucky completed a two kiln expansion. With the  Black
River  expansion on-line, Dravo Lime's annual quicklime  capacity
totals  approximately  three million tons.   This  capacity  will
further increase to slightly over 3,300,000 ton-per-year, when  a
fourth  1,000  ton-per-day  kiln now  in  the  process  of  being
engineered and constructed at its Maysville, Kentucky facility is
completed in the first quarter of 1997.

The  Maysville plant, currently a three kiln, 1,050,000  ton-per-
year  facility  near  Maysville, Kentucky,  produces  a  material
marketed  under  the  trade name Thiosorbicr  Lime,  that  has  a
product chemistry ideally suited for removing sulfur dioxide from
power  plant stack gases.  All of Maysville's output is committed
under  long-term  contracts with utility companies  in  the  Ohio
Valley  region.   All  contracts  contain  provisions  for  price
escalation.   Owned reserves at the Maysville site are  recovered
from  a mine 950 feet underground and are considered adequate  to
sustain the future four kiln operation in excess of twenty years.
Dravo Lime also holds options on additional limestone reserves to
sustain production for an additional thirty year period.

                                
                                
                               -3-
Item 1.  Business (continued)

With  the  completion  of the current two kiln  expansion,  Dravo
Lime's   Black  River  facility  is  an  integrated   Thiosorbicr
quicklime, high calcium pebble and
pulverized quicklime, and bulk and bagged hydrated lime facility.
Located along the Ohio River at Butler, Kentucky, Black River has
an  annual quicklime capacity of 1,350,000 ton-per-year.  Of that
total,  in  excess  of  seventy percent is committed  to  utility
companies  and  steel  and paper customers under  contracts  with
price  escalation provisions.  Limestone reserves at Black  River
are  recovered from a 600-feet-deep underground mine.   At  Black
River's  expanded  rate  of  capacity,  reserves  are  considered
adequate  to sustain production levels for more than seventy-five
years.

The   company's  Longview  facility,  located  near   Birmingham,
Alabama,  is  an integrated facility as well that  produces  high
calcium  quicklime, and bulk and bagged hydrated lime from  owned
limestone  reserves.   At this plant, Dravo  Lime  also  produces
dolomitic  quicklime  from  limestone  purchased  from  a  nearby
dolomitic stone quarry.  Due to its material handling and storage
capabilities  and  its  ability  to  produce  high  calcium   and
dolomitic  lime,  the Longview facility is able to  custom  blend
quicklime  to its customers' chemical specifications.  Longview's
annual production capacity is approximately 570,000 ton-per-year.
Limestone  at  the Longview operation comes from an  quarry  with
recoverable reserves estimated to last approximately twenty years
at  the  current production rate.  Ultimately, Dravo Lime expects
to  convert Longview to an underground mine, providing access  to
additional  reserves  sufficient to  support  current  production
rates for over sixty years.

In  conjunction with the sale of Dravo Basic Materials' assets to
Martin  Marietta,  Dravo Lime entered into agreements  appointing
Martin  Marietta  the  exclusive  distributor  of  aggregate  by-
products  produced  when limestone is crushed and  screened  into
kiln  feed.   During  1995, an aggregates  processing  plant  was
constructed at the Longview facility that is expected to  produce
from  500,000   to  1,000,000  tons of  aggregates  annually  for
purchase  by Martin Marietta.  A benefit of this installation  is
to  make  a  marketable by-product, which reduces the cost  Dravo
Lime  incurs to recover the high calcium limestone reserves  that
are beneath the aggregate quality material.

Dravo   Lime   products   are   distributed   through   quicklime
distribution  terminals  located  in  Butler  and  Belle  Vernon,
Pennsylvania; Porterfield, Ohio; Brunswick, Georgia;  and  Tampa,
Fort Lauderdale and Sanford, Florida.  At Baton Rouge, Louisiana,
Dravo  Lime  owns  and  operates a  lime  hydration  and  bagging
facility from which quicklime, and bulk and bagged hydrated  lime
products are distributed.

(b)  Competitive Conditions

Dravo  encounters competition at all its operations but  believes
that its experience, strategically located reserves and technical
expertise  in  the  flue  gas desulfurization  industry  give  it
certain competitive advantages.


                               -4-
Item 1. Business (continued)

Dravo's  research and development expenditures were $3.6  million
in  1995  and  $4.4  million in 1994.  Research  and  development
spending in 1996 is expected to exceed $3.1 million.  The company
expects  the  research, much of which is being conducted  jointly
with  utility customers, to lower both the capital and  operating
costs  associated with flue gas desulfurization (FGD).   A  major
advancement toward that goal was achieved with the development of
a  second generation, proprietary ThioClearR FGD technology.   An
agreement  in principle has been reached to develop a  commercial
scale  demonstration  using  this technology  at  Applied  Energy
Services'   Beaver  Valley  cogeneration  facility   in   Monaca,
Pennsylvania.   Other research projects are aimed  at  developing
proprietary technologies for use in reducing stack gas  emissions
of   combined  SOx/NOx  and  air  toxins  while  recovering   and
processing  salable  by-products.  Dravo believes  that  in  this
field   its  long-term  contracts,  accumulated  experience   and
technical skill represent significant competitive advantages.

Several firms with which Dravo competes have comparable resources
and  income.   Dravo  competes with  other  firms  for  qualified
professional personnel, particularly those with technical skills.

(c)  Corporate Development

Dravo's  corporate development policy encompasses growth  through
investment  in  existing  businesses,  internal  development  and
acquisition.  Additionally, to the extent that business units  no
longer  meet  management's  long-term  profitability  performance
criteria   and   business  strategies,  or  do   not   contribute
significantly to corporate objectives, a policy of divestiture is
followed.

Continuing operations of Dravo Corporation, which are principally
domestic  in nature, function in one segment, a natural  resource
business,  primarily involved in the production,  processing  and
supply  of lime for environmental, metallurgical, pulp and paper,
municipal, construction and miscellaneous chemical and industrial
applications as well as the development and marketing of  related
environmental  technologies,  products  and  services.    Dravo's
position  as  the world's leading producer of lime for  flue  gas
desulfurization applications was enhanced by the passage  of  the
1990 Clean Air Act Amendments.

               Description of Dravo Capital Stock

General

Under its Restated Articles of Incorporation ("the Articles"), as
amended,  Dravo  is  authorized  to  issue  1,878,870  shares  of
preference  stock,  par  value $1.00 per  share,  and  35,000,000
shares  of common stock, par value $1.00 per share.  At  December
31,  1995  issued preference and common shares were  225,386  and
15,055,237, respectively and there were 347,691 shares of  common
stock held in the treasury.

Four  series  of  preference  stock  have  been  established   by
resolutions   of  the  Board  of  Directors:   $2.20   Cumulative
Convertible  Series  A  Preference Stock  ("Series  A  Preference
Stock"),  consisting  of 26,817 shares, issued  on  September  1,
1970;  $2.475  Cumulative Convertible Series B  Preference  Stock
("Series  B  Preference Stock"), consisting  of  165,516  shares,
issued on June 12, 1973; Series C Preference Stock consisting  of
200,000  shares, which are issuable pursuant to the  exercise  of
the rights to purchase stock described below; and $12.35 Series D
Cumulative  Convertible Exchangeable Preference Stock ("Series  D
Preference  Stock")  consisting  of  200,000  shares,  issued  on
September  21,  1988.  All of the shares of Series  A  Preference
Stock  were  converted into shares of common stock  on  April  2,
1978.   Presently there are 25,386 shares of Series B  Preference
Stock and 200,000 shares of Series D Preference Stock issued  and
outstanding.   No shares of Series C Preference Stock  have  been
issued or are outstanding.  Other series of preference stock  may
be  created  by  resolution of the Board of Directors  with  such
dividend,  liquidation, redemption, sinking fund  and  conversion
rights as shall be specified therein.

Dividend Rights

The  holders  of the preference stock are entitled to  cumulative
dividends,  payable quarterly, which must be paid  and  the  next
quarterly  dividend  set  apart  before  any  dividends   (except
dividends in common stock or any other

stock  ranking  after the preference stocks as to  dividends  and
assets)  are  declared,  or paid, or monies  set  apart  for  the
payment  of  dividends on any class of stock  ranking  after  the
preference  stock  as  to  dividends  or  assets.   The  rate  of
dividends  payable upon the Series B Preference Stock  is  $2.475
per  annum.   The  rate of dividends payable upon  the  Series  C
Preference  Stock is an amount per share (rounded to the  nearest
cent)  equal to the greater of $10.00 or 100 times the  aggregate
per  share  amount  of all cash and non-cash dividends  or  other
distributions, other than a dividend or distribution  payable  in
shares  of  common  stock,  paid  on  the  common  stock  in  the
immediately preceding quarter, subject to adjustment  in  certain
events.   The  rate  of  dividends  payable  upon  the  Series  D
Preference Stock is 12.35 percent per annum or $12.35 per  share,
which  rate  shall be increased by 2 percent per  annum  if  such
dividends  are  not paid on any quarterly dividend  payment  date
until  accrued  and unpaid dividends on the Series  D  Preference
Stock are paid.

The holders of the common stock are entitled to such dividends as
may  be declared by the Board of Directors out of assets properly
available for that purpose.  No common stock dividends have  been
declared since April, 1987.

Other  information  required  by this  item  is  incorporated  by
reference to the information set forth under the caption "Note 5:
Notes Payable", in the Notes to Consolidated Financial Statements
on  pages  24  and  25 of the 1995 Annual Report to  Shareholders
which accompanies this report.

Voting Rights

Each  share  of  the  common stock and the  preference  stock  is
entitled  to  one  vote, which is cumulative in the  election  of
directors.  The Board of Directors is divided into three classes,
and  approximately one third of the directors  are  elected  each
year for three year terms.  The effect of such classification  of
the   Board   is   to  increase  the  number  of  shares,   voted
cumulatively, necessary to elect directors.  If dividends on  the
preference stock shall be unpaid or in arrears for six  quarterly
dividend periods, the holders of the preference stock voting as a
class shall have the right to elect two additional directors.

In  the  event  of  the voluntary or involuntary  liquidation  or
dissolution  of  Dravo,  or  the sale  or  other  disposition  of
substantially  all of its assets, the holders  of  the  Series  B
Preference Stock shall be entitled to receive the sum of $55  per
share  plus  all  accumulated and unpaid dividends  thereon;  the

Item  5.   Market for the Registrant's Common Stock  and  Related
Stockholder            Matters (continued)

Liquidation Rights (continued)

after  payment of all liabilities, liquidation preferences and  a
distribution on the common stock, if any, as determined according
to  a formula; and the holders of Series D Preference Stock shall
be  entitled  to receive $100 per share plus all accumulated  and
unpaid  dividends thereon.  The holders of any  other  series  of
preference stock which may be issued shall be entitled to receive
the amounts provided for in the resolutions creating such series.
The  holders  of  the  common stock shall share  ratably  in  the
remaining assets, if any.

No Preemptive Rights and Non-assessability

No preemptive rights attach to the common stock or the preference
stock.   Neither  the  holders  of  the  common  stock  nor   the
preference  stock  are liable to further calls or  assessment  by
Dravo.

Redemption and Sinking Fund Provisions

There  are  no redemption provisions with respect to  the  common
stock.   The Series B Preference Stock may be redeemed, in  whole
or  in  part,  at the option of Dravo, on not less than  60  days
notice, on any quarterly dividend payment date by the payment  of
$55  per  share and all accumulated and unpaid dividends  to  the
redemption  date.  The Series C Preference Stock may be  redeemed
as a whole, but not in part, at the option of Dravo, at any time,
at a cash price per share based upon the average market value, as
defined  and  adjusted, of the common stock plus all accrued  but
unpaid  dividends.  The Series D Preference Stock may be redeemed
in  whole  or  in part at the option of Dravo at any  time  after
January  21,  1996,  by the payment of $100  per  share  and  all
accumulated and unpaid dividends to the redemption date, so  long
as  the  current  market price (as defined in the Certificate  of
Designations, Preferences and Rights for the Series D  Preference
Stock)  of  the  common stock on the date the  Board  decides  to
redeem  the shares is at least 175 percent of the then  effective
conversion  price for the Series D Preference Stock.   Commencing
on  the first quarterly dividend payment date after September 21,
1998  and annually thereafter, Dravo is required to redeem 50,000
shares  of  Series D Preference Stock in cash at  the  redemption
price   of  $100  per  share  plus  all  accumulated  and  unpaid
dividends.  Dravo is also required (unless certain conditions are
met)  to  redeem all of the then outstanding shares of  Series  D
Preference  Stock in cash at $100 per share plus all  accumulated
and  unpaid dividends (a) if Dravo declares or pays or sets apart
for payment any dividends or makes any other distribution in cash
or  other  property on or in respect of the common stock  or  any
other  class  or  series of the capital stock  of  Dravo  ranking
junior  to  the  Series  D  Preference Stock  as  to  payment  of
dividends ("Junior Dividend Stock"), or sets apart money for  any
sinking fund or analogous fund for the redemption or purchase  of
any   Junior   Dividend  Stock  and  (b)  upon  any   merger   or
consolidation of Dravo if, in connection therewith,  the  holders
of  the common stock receive cash, debt instruments or preference
stock  of  the surviving entity which ranks on a parity  with  or
senior  to  the  Series  D  Preference  stock  with  respect   to
liquidation, dissolution or winding up or dividends.   There  are
no  sinking fund provisions with respect to the common  stock  or
the  Series  B  Preference Stock, Series C  Preference  Stock  or
Series D Preference Stock.

Item  5.   Market for the Registrant's Common Stock  and  Related
Stockholder            Matters (continued)

Conversion

The  Series  B Preference Stock is presently convertible  at  any
time  prior to redemption at the option of the holder into common
stock on the basis of 3.216 shares of common stock for each share
of  Series B Preference Stock, subject to equitable adjustment in
the  event  of certain changes affecting the common  stock.   The
Series  D  Preference Stock is presently convertible at any  time
prior to redemption at the option of the holder into common stock
on  the  basis  of 8.0 shares of common stock for each  share  of
Series D Preference Stock, subject to adjustment in the event  of
certain  changes  affecting  the  common  stock.   The  Series  D
Preference Stock is convertible or exchangeable in whole  at  any
time   by  Dravo  for  an  equal  face  amount  of  Dravo  Senior
Subordinated Convertible Notes due September 21, 2001  containing
the same conversion rights, transfer restrictions and other terms
(other  than  voting  rights) as the Series D  Preference  Stock.
There  are  no  conversion rights with respect to  the  Series  C
Preference Stock or the common stock.

Rights to Purchase Series C Preference Stock

The  Series  C  Preference  Stock is  issuable  pursuant  to  the
exercise  of  rights to purchase Series C Preference  Stock.   On
April 4, 1986, the Board of Directors declared a distribution  of
one  right  for  each  outstanding  share  of  common  stock   to
shareholders of record at the close of business on April 17, 1986
(the  "Record  Date") and with respect to each  share  of  common
stock that may be issued by Dravo prior to the Distribution  Date
described  below or the earlier redemption or expiration  of  the
rights.  Each right entitles the registered holder, following the
occurrence  of  certain events described below, to purchase  from
Dravo  a  unit  consisting of one one-hundredth  of  a  share  (a
"Unit") of Series C Preference Stock at a purchase price  of  $60
per  Unit,  subject  to adjustment (the "Purchase  Price").   The
descriptions and terms of the rights are set forth  in  a  rights
agreement (the "Rights Agreement") between Dravo and PNC Bank, N.
A. (formerly Pittsburgh National Bank), as the rights agent.

Initially,  the  rights  will be attached  to  all  common  stock
certificates  representing  shares  then  outstanding,   and   no
separate  rights  certificates will be distributed.   The  rights
will  separate from the common stock and a distribution date will
occur  upon  the  earlier  of  (a) 10  days  following  a  public
announcement  that a person or group of affiliated or  associated
persons  (an  "Acquiring Person") has acquired, or  obtained  the
right  to acquire, beneficial ownership of 20 percent or more  of
the  outstanding  shares of common stock  of  Dravo  (the  "Stock
Acquisition  Date"),  or  (b)  10  business  days  following  the
commencement  of  a  tender offer or exchange  offer  that  would
result  in  a person or group beneficially owning 30  percent  or
more  of  such  outstanding shares of common  stock.   Until  the
distribution date, (i) the rights will be evidenced by the common
stock  certificates and will be transferred with  and  only  with
such   common   stock  certificates,  (ii)   new   common   stock
certificates issued after the Record Date will contain a notation
incorporating  the Rights Agreement by reference, and  (iii)  the
surrender  for  transfer  of  any certificate  for  common  stock
outstanding  will  also  constitute the transfer  of  the  rights
associated with the common stock represented by such certificate.

Item  5.   Market for the Registrant's Common Stock  and  Related
Stockholder            Matters (continued)

Rights to Purchase Series C Preference Stock (continued)

The  rights are not exercisable until the distribution  date  and
will  expire  at the close of business on April 17, 1996,  unless
earlier redeemed by Dravo as described below.

In  the event that, at any time following the distribution  date,
(a)  Dravo  is  the  surviving corporation in a  merger  with  an
Acquiring  Person  and  its  common  stock  is  not  changed   or
exchanged,  (b) an Acquiring Person becomes the beneficial  owner
of  30  percent or more of the then outstanding shares of  common
stock,  (c)  an  Acquiring Person engages in one or  more  "self-
dealing"  transactions as set forth in the Rights  Agreement,  or
(d)  during such time as there is an Acquiring Person,  an  event
occurs   which  results  in  such  Acquiring  Person's  ownership
interest  being  increased  by more than  one  percent  (e.g.,  a
reclassification   of   securities,  reverse   stock   split   or
recapitalization  of  Dravo),  each  holder  of  a   right   will
thereafter have the right to receive, upon exercise, common stock
(or, in certain circumstances, cash, property or other securities
of Dravo) having a value equal to two times the Purchase Price of
the  right.  Notwithstanding any of the foregoing, (i) rights are
not exercisable following the occurrence of any of the events set
forth  in  this  paragraph until such time as the rights  are  no
longer redeemable by Dravo as set forth below, and (ii) following
the  occurrence of any of the events set forth above, all  rights
that are, or (under certain circumstances specified in the Rights
Agreement) were, beneficially owned by any Acquiring Person  will
be null and void.

In  the  event that, at any time following the stock  acquisition
date,  (i)  Dravo  is  acquired in a  merger  or  other  business
combination  transaction  in which Dravo  is  not  the  surviving
corporation  (other  than  a merger described  in  the  preceding
paragraph), or (ii) 50 percent or more of Dravo assets or earning
power  is  sold  or transferred, each holder of a  right  (except
rights  which  previously have been voided as  set  forth  above)
shall thereafter have the right to receive, upon exercise, common
stock  of the acquiring company having a value equal to two times
the  exercise price of the right.  The events set forth  in  this
paragraph and in the preceding paragraph are referred to  as  the
"Triggering Events."

The  Purchase Price payable, and the number of units of Series  C
Preference  Stock or other securities or property issuable,  upon
exercise  of  the rights are subject to adjustment from  time  to
time to prevent dilution.  No fractional units may be issued and,
in  lieu thereof, an adjustment in cash may be made based on  the
market price of the Series C Preference Stock on the last trading
date prior to the date of exercise.

At  any time until ten days following the stock acquisition date,
Dravo may redeem the rights in whole, but not in part, at a price
of  $.01 per right.  Under certain circumstances set forth in the
Rights  Agreement,  the  decision to  redeem  shall  require  the
concurrence  of  a  majority  of  the  continuing  directors,  as
defined.   After the redemption period has expired and  prior  to
the occurrence of a Triggering Event, Dravo's right of redemption
may  be  reinstated if an Acquiring Person reduces his beneficial
ownership to 10


                              -12-
Item  5.   Market for the Registrant's Common Stock  and  Related
Stockholder
        Matters (continued)

Rights to Purchase Series C Preference Stock (continued)

percent  or less of the outstanding shares of common stock  in  a
transaction  or  series  of  transactions  not  involving  Dravo.
Immediately  upon  action  of  the Board  of  Directors  ordering
redemption  of the rights, with, where required, the  concurrence
of  the  continuing directors, the rights will terminate and  the
only  right of the holders of rights will be to receive the  $.01
redemption price.

Until  a  right is exercised, the holder thereof, as  such,  will
have  no  rights  as  a shareholder of Dravo, including,  without
limitation, the right to vote or to receive dividends.

Other  than  those provisions relating to the principal  economic
terms  of  the  rights,  any  of the  provisions  of  the  Rights
Agreement may be amended by the Board of Directors of Dravo prior
to  the  distribution date.  Thereafter, the  provisions  of  the
Rights  Agreement  may  be  amended  by  the  Board  (in  certain
circumstances, with the concurrence of the continuing  directors)
in  order  to  cure any ambiguity, to make changes which  do  not
adversely  affect  the interests of holders of rights  (excluding
the   interests  of  any  Acquiring  Person),  to   suspend   the
effectiveness  of the provision of the Rights Agreement  pursuant
to  which  certain rights become void as described above,  or  to
shorten  or  lengthen any time period under the Rights Agreement;
provided,  however, that no amendment to adjust the  time  period
governing redemption shall be made at such time as the rights are
not redeemable.

The rights may have the effect of preventing or discouraging some
attempts  to  acquire control of Dravo.  The rights  could  cause
substantial  dilution  to  a person or  group  that  attempts  to
acquire  control of Dravo on terms not approved by its  Board  of
Directors,  unless  the  offer is conditioned  on  a  substantial
percentage  of  rights  being tendered to  and  acquired  by  the
Acquiring  Person.   The  rights should not  interfere  with  any
merger  or  other business combination approved by the  Board  of
Directors prior to the expiration of the redemption period  since
the  rights  may be redeemed by Dravo prior to the expiration  of
such  period and Dravo may suspend the provisions that in certain
circumstances  prevent an Acquiring Person  from  exercising  its
rights.  The rights could interfere with a negotiated transaction
after  an acquisition of 20 percent or more voting power  if  the
rights  were not redeemed.  The rights will not prevent a  holder
of a controlling interest from exercising control over Dravo.

The  Board of Directors has decided not to extend the rights past
the April 17, 1996 expiration date.

A copy of the Rights Agreement has been filed with the Securities
and Exchange Commission as an Exhibit to a Report on Form 8-K.  A
copy  of  the  Rights Agreement is available free of charge  from
Dravo   upon  the  request  of  any  shareholder.   This  summary
description of the Rights does not purport to be complete and  is
qualified in its entirety by reference to the Rights Agreement.

                  INDEPENDENT AUDITORS' REPORT



The Board of Directors and Shareholders
Dravo Corporation:

Under  date  of January 24, 1996, we reported on the consolidated
balance  sheets  of  Dravo Corporation  and  subsidiaries  as  of
December  31,  1995,  and  1994,  and  the  related  consolidated
statements of operations, retained earnings, and cash  flows  for
each  of  the  years in the three-year period ended December  31,
1995, as contained in the 1995 annual report to shareholders.  As
discussed  in  Notes  10  and  13 to the  consolidated  financial
statements,  the  company adopted the method  of  accounting  for
postemployment  benefits  prescribed by  Statement  of  Financial
Accounting  Standards  No.  112  in  1994  and  the  methods   of
accounting  for postretirement benefits other than  pensions  and
income  taxes  prescribed by Statements of  Financial  Accounting
Standard  Nos.  106  and  109,  respectively,  in  1993.    These
consolidated  financial  statements and our  report  thereon  are
incorporated by reference in the annual report on Form  10-K  for
the   year   1995.   In  connection  with  our  audits   of   the
aforementioned consolidated financial statements, we also audited
the  related financial statement schedule as listed in answer  to
Item   14(a)(2).   The  financial  statement  schedule   is   the
responsibility  of the company's management.  Our  responsibility
is  to  express  an  opinion on the financial statement  schedule
based on our audits.

In   our   opinion,  such  financial  statement  schedule,   when
considered  in  relation  to  the  basic  consolidated  financial
statements  taken as a whole, presents fairly,  in  all  material
respects, the information set forth therein.

Note 2:  Income Taxes

The  company adopted Statement of Financial Accounting  Standards
No.  109  "Accounting  for  Income Taxes"  (SFAS  109)  effective
January  1,  1993.   The  cumulative effect  of  this  change  in
accounting  for  income taxes of $276,000  is  determined  as  of
January  1, 1993 and is reported separately in the Statements  of
Operations  for  the year ended December 31, 1993.   Prior  years
financial statements were not restated to apply the provisions of
SFAS 109.

Dravo  Corporation files a consolidated federal income tax return
which  includes the parent and consolidated subsidiaries.   Dravo
Corporation parent company financial statements recognize current
income  tax  benefits to the extent the benefits  are  offset  by
current  income tax liabilities of the consolidated subsidiaries.
Long-term  deferred  income tax benefits are  recognized  to  the
extent  that  it  is more likely than not that the  company  will
generate  sufficient consolidated taxable income to  utilize  net
operating loss carryforwards prior to their expiration.





                              -31-

significant portions of the deferred tax assets and deferred  tax
liabilities at December 31 are as follows:

  Net deferred tax asset                        $24,853  $24,853
</TABLE>
Management  believes  it is more likely than  not  that  the  net
deferred tax asset of $24.9 million will be realized through  the
reversal  of  temporary differences and through its  subsidiaries
future  income.  In order to fully realize the net  deferred  tax
asset,  the  parent  company and its subsidiaries  will  need  to
generate  future  taxable income of approximately  $73.2  million
prior  to the expiration of its net operating loss carryforwards.
There  can  be  no assurance, however, that the  parent,  or  its
subsidiaries, will generate any earnings or any specific level of
continued earnings.

                               ARTICLE I
                          Board of Directors

     SECTION 1.     The Board of Directors shall consist of not less
than two and not more than twelve persons to be elected by the
shareholders as herein provided, the exact number to be determined from
time to time by proper resolution of the Board of Directors. The
Directors shall be classified with respect to the time during which
they shall severally hold office, by dividing them into three classes,
each consisting as nearly as possible of the same number of Directors.
At each annual meeting of the shareholders, Directors in the number for
those whose terms then expire shall be elected to serve for terms of
three years, except that the number of Directors to be elected to such
terms shall be adjusted if the number of Directors shall have been
decreased as provided herein so as to eliminate the place of a Director
whose term then expires.

     Nominations for election to the Board of Directors may be made by
the Board of Directors or by any shareholder of the Corporation
entitled to notice of, and to vote at, any meeting called for the
election of Directors. Nominations, other than those made by or on
behalf of the Board of Directors of the Corporation, shall be noticed
in writing and shall be received by the Secretary of the Corporation
not later than (i) with respect to an election of directors to be held
at an annual meeting of shareholders, ninety (90) days prior to the
anniversary date of the immediately preceding annual meeting, and (ii)
with respect to an election of directors to be held at a special
meeting of shareholders, the close of business on the fifteenth (15th)
day following the date on which notice of such meeting is first given
to shareholders or public disclosure of the meeting is made. Such
notification shall contain the following information to the extent
known to the notifying shareholder: (a) the name and residence address
of each proposed nominee and of the notifying shareholder; (b) the
principal occupation of each proposed nominee; (c) a representation
that the notifying shareholder intends to appear in person or by proxy
at the meeting to nominate the person or persons specified in the
notice; (d) the total number of shares of the Corporation that will be
voted for each proposed nominee; (e) the total number of shares of the
Corporation owned by the notifying shareholder; (f) a description of
all arrangements or understandings between the notifying shareholder
and each nominee and any other person or persons (naming such person or
persons) relating to such nomination or nominations by the notifying
shareholder; (g) such other information regarding each nominee proposed
by such shareholder as would be required to be included in a proxy
statement filed with the Securities and Exchange Commission; and (h)
the consent of each nominee to serve as a director of the Corporation
if so elected. If the information submitted to the Corporation within
the time prescribed above is determined by the Chairman of the Board of
the Corporation to be deficient in any manner, the Chairman shall
advise the notifying shareholder in writing of such deficiencies not


                                                                 Page 2
                                                                By-Laws


later than the close of business on the fifth (5th) day following the
date that the Corporation first received written notice of the
nomination made by the notifying shareholder. The notifying shareholder
must thereafter cure such deficiencies by sending a revised
notification to the Secretary of the Corporation setting forth the
required information which must be received by the Secretary in writing
not later than the fifth (5th) day following the date that the
notifying shareholder received notice from the Corporation of the
deficiencies in the notifying shareholder's written nomination.
Notwithstanding the above, these nominating procedures shall not apply
to any special meeting of the shareholders of the Corporation called
for the election of directors for which notice of the meeting was not
given to shareholders at least twenty (20) days prior to the meeting.
The chairman may disregard and refuse to recognize any nomination
determined by him not to have been made in accordance with the
foregoing procedures.

     If a vacancy occurs in the Board of Directors from any cause,
including any increase in the number of Directors in the manner
prescribed in this Section, a majority of the remaining members of the
Board of Directors, though less than a quorum, shall have the power to
elect a Director to fill such vacancy to serve for the balance of the
unexpired term of the vacating director and until his or her successor
has been elected and qualified.

     In the case of an increase in the number of Directors in the
manner specified in this Section, the additional offices so created
shall be assigned by the Board of Directors to the appropriate class so
that the three classes shall continue to consist, as nearly as
possible, of the same number of Directors.
     At any shareholders' meeting at which Directors are to be elected,
separate elections shall be held for the Directors of each class then
to be elected.

     The Directors shall hold office during the terms for which they
have been elected and until their successors are elected and qualified.

     SECTION 2.     The Board of Directors may, by resolution adopted
by a majority of the whole Board, designate one or more committees,
each committee to consist of two or more of the Directors of the
Corporation. Standing committees shall include the Audit and Finance
Committee and the Compensation and Nominating Committee, each of which
shall be comprised exclusively of Directors who are not current
employees of the Corporation.
                                                                 Page 3

     SECTION 3.     The Board of Directors, as soon as reasonably
possible after each annual meeting of shareholders, shall hold a
meeting to organize, elect officers of the Corporation and transact
other business.

     Regular meetings of the Board of Directors may be held without
notice at such time and place as shall from time to time be determined
by the Board of Directors and may be adjourned by the members present
to any other time and place.

     Special meetings may be called at any time by the chief executive
officer or any two members of the Board of Directors upon at least 24
hours' notice, which need not be in writing.

     A majority of the Directors in office shall constitute a quorum
for the transaction of business.

     If all the Directors shall severally or collectively consent in
writing to any action to be taken by the Corporation, such action shall
be as valid corporate action as though it had been authorized at a
meeting of the Board of Directors.

     One or more Directors may participate in a meeting of the Board of
Directors, or of a committee thereof, by means of conference telephone
or similar communications equipment by means of which all persons
participating in the meeting can hear each other.

     SECTION 4.     The Board of Directors shall have the right to
adopt such rules and regulations for the conduct of business, and from
time to time alter and amend the same, as to them may seem proper.

     SECTION 5.     The Board of Directors (or the Compensation
Committee by delegation from the Board), shall fix the compensation of
the officers of the Corporation and such other employees who are
designated by the Board of Directors as holding major positions of
authority in the Corporation.

or was a party or is threatened to be made a party to or is involved
(as a witness or otherwise) in any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative and whether or not by or in the right of the Corporation
or otherwise (hereafter a "proceeding"), by reason of the fact that he
or she is or was a Director or officer or employee of the Corporation,
or is or was serving at the request of the Corporation as a Director,
officer or trustee or employee of another corporation, partnership,
joint venture, trust or other enterprise, including service with
respect to an employee benefit plan, or by reason of any action alleged
to have been taken or not taken by him or her while acting in any such
capacity, against expenses (including attorneys' fees) and all
liability and loss, including  judgments,  fines,  ERISA  excise  taxes
and  penalties and amounts paid or to be paid in settlement (whether
with or without court approval), actually and reasonable incurred by
him or her in connection with such threatened, pending or completed
action, suit or proceeding, except to the extent prohibited by law as
the same exists or may hereafter be amended (except in the case of any
such amendment which has the effect of narrowing indemnification rights
that the Corporation was permitted to provide prior to such amendment);
provided, however, that except with respect to claims described in
Section 2 hereof, the Corporation shall indemnify any such person
seeking indemnification in connection with a proceeding (or part
thereof), initiated by such person only if such proceeding (or part
thereof) was authorized by the Board of Directors of the Corporation.
Subject to the foregoing indemnification, the right to indemnification
conferred in this Section shall include the right to be paid by the
Corporation expenses incurred; provided, however, that to the extent
required by law, the payment of such expenses in advance of the final
disposition of a proceeding shall be made only upon receipt of an
undertaking by or on behalf of such person to repay such amounts if it
shall ultimately be determined that he or she is not entitled to be
indemnified under this Article or otherwise.

     SECTION 2.     If a claim under Section 1 is not paid in full by
the Corporation within forty-five (45) days after a written claim has
been received by the Corporation, the claimant may, at any time
thereafter, bring suit against the Corporation to recover the unpaid
amount of the claim. The claimant shall also be entitled to be paid the
expenses of prosecuting such claim to the extent he or she is
successful in whole or in part on the merits or otherwise in
establishing his or her right to indemnification or to the advancement
of expenses.

     SECTION 3.     The right to indemnification, including the right
to the advancement of expenses, conferred in this Article shall not be
exclusive of any other rights to which a person seeking indemnification

agreement, vote of shareholders, or directors or otherwise, both as to
action in his or her official capacity and as to action in any other
capacity while holding that office.

     SECTION 4.     The Corporation may create a fund of any nature,
which may, but need not be, under the control of a trustee, or
otherwise secure or insure in any manner its indemnification
obligations, including its obligation to advance expenses, whether
arising under or pursuant to this Article or otherwise.

     SECTION 5.     The Corporation shall have the express authority to
enter into such agreements as the Board of Directors deem appropriate
for the indemnification of, including the advancement of expenses to,
present or future Directors, officers and employees of the Corporation
in connection with their service to, or status with, the Corporation or
any other corporation, partnership, joint venture, trust or other
enterprise, including any employee benefit plan, for whom such person
is serving at the request of the Corporation.

to the advancement of expenses provided herein, shall be a contract
right, shall continue as to a person who has ceased to be a director,
officer, employee, or to serve in any other of the capacities described
herein, and shall inure to the benefit of the heirs, executors and
administrators of such person. Notwithstanding any amendment,
alteration or repeal of this Article or any of its provisions or the
adoption of any provision inconsistent with this Article or any of its
provisions, any person who is or was a director, officer or employee or
is or was serving at the request of the Corporation as a director,
officer, employee, or trustee of another corporation or of a
partnership, joint venture, trust or other enterprise, including
service with respect to employee benefit plans, shall be entitled to
indemnification, including the right to the advancement of expenses, in
accordance with the provisions hereof and thereof with respect to any
action taken or omitted prior to such amendment, alteration or repeal
or the adoption of such inconsistent provision except to the extent
such amendment, alteration, repeal or inconsistent provisions provides

               (iii)     The notice, if any, of the exercise of the Term
               Loan Option shall be submitted by the Borrowers in writing
               to the Agent at least 60 Business Days prior to the Maturity
               Date, and shall specify the portion of the Revolving Line of
               Credit for which the Term Loan Option is being exercised and
               the initial Interest Period, if any.  Any notice shall be
               irrevocable once given.
     
               (iv) On the date of conversion to a Term Loan, the
               Borrowers shall pay to Lenders in immediately available
               funds a fee equal to .25 of 1% of the Converted Amount. 
               Such fee shall be shared pro rata by Lenders.
          
               (c)  Notes.
     
               (i)  Revolving Notes.  All sums advanced pursuant to
               the Revolving Line of Credit shall be payable, as to both
               principal and interest, and shall bear interest, at the rate
               and in the manner provided herein and in the Revolving Notes
               of Borrowers, copies of which are attached hereto, marked
               Exhibits A-1, A-2 and A-3, and expressly made a part hereof
               as though fully set forth herein (the "Revolving Notes"). 
               Borrower shall execute and deliver to Lenders the Revolving

               liability of Borrowers to Lenders for the principal
               indebtedness of the Revolving Line of Credit shall be
               limited to the net principal amount actually advanced by
               Lenders to Borrowers under the Revolving Notes.  All
               advances under the Revolving Note shall be evidenced by
               Lenders' records with respect to such advances, which
               records shall be prime facie evidence as to the amount at
               any time due such Lender hereunder.  All advances under the
               Revolving Line of Credit shall be made pursuant to the
               procedures set forth hereinbelow in Article IX.  Borrowers
               irrevocably authorize Lenders to disburse any Revolving Line
               of Credit loans made hereunder for the account of the
               Borrowers either to Lime or to Dravo Natural Resources
               Company ("DNRC") pursuant to the DNRC Agency Agreement.

               interest, and shall bear interest, at a rate and in the
               manner provided herein and the Term Notes, executed and
               delivered by each of the Borrowers and in form and substance
               satisfactory to each of the Lenders (the "Term Notes").
     
          (ii) The fourth sentence of Section 1.3 is amended by

     date "July 31, 1997".
     
          (iii)     The last sentence of Section 1.5 is amended by deleting
     the date "June 30" and substituting therefor the date "July 31".

          (v)  Section 1.9(a) is amended in its entirety to read as
     follows:
     
                    "(a) At least 10 but not more than 60 days
                    before each May 31, commencing May 31, 1996, the
                    Borrowers may, by delivering a written request to the
                    Agent (each such request being irrevocable), request
                    that each Lender extend for one year the Maturity Date
                    with respect to such Lender's Revolving Line of Credit
                    commitment and commitment to issue (or cause to be
                    issued) Letters of Credit (such commitments referred
                    to herein collectively, with respect to each Lender,
                    as such Lender's "Commitment").  The Agent shall, upon
                    its receipt of such a request, promptly notify each
                    Lender thereof, and request that each Lender promptly
                    advise the Agent of its approval or rejection of such
                    request."
     
          (b)       Amendment to Article V.  Section 5.1(b)(1) is amended
     by deleting the phrase "and in the Note Purchase Agreement"

     of the Dravo Parties set forth herein".
     
          (c)       Amendments to Article IX.  Article IX shall be amended
     as follows:
     
                    (i)  Section 9.1 is amended by deleting in its
                    entirety each of the following subsections (c), (d)
                    and (e):
     
                    (c)  Notwithstanding subsections (a) and (b)
                    above, in the event that any Lender does not agree to
                    provide any funds (to the extent that such funds are
                    not otherwise available to be borrowed by the
                    Borrowers from such Lender pursuant to this Agreement)
                    for (i) the cure of any defaults pursuant to Article
                    6 of the Project Intercreditor Agreement or (ii) the
                    purchase price of any assets sold by Lime SPV in
                    connection with the exercise by the Lenders of any
                    right of first refusal pursuant to Section
                    5.03(a)(iv)(2) of the Override Agreement, the Lenders
                    that agree to provide such funds (the "Funding
                    Lenders") shall advance such funds on a pro rata
                    basis, based on the proportion of each Funding
                    Lender's Commitment to the aggregate amount of the
                    Commitments of the Funding Lenders.  So long as no
                    Event of Default shall have occurred and be
                    continuing, notwithstanding Section 11.7, any amounts
                    of principal prepaid or repaid by the Borrowers
                    pursuant to this Agreement shall be applied, first, to
                    the repayment of all advances made by the Funding
                    Lenders pursuant to clauses (i) and (ii) above (on a
                    pro rata basis based on the amount of advances made by
                    each of the Funding Lenders) and second, to the
                    repayment of all other amounts owing to the Lenders
                    hereunder (on a pro rata basis in accordance with
                    their respective percentages set forth in subsection
                    (a) above), in each case otherwise in accordance with
                    this Agreement.  Upon the occurrence and during the
                    continuance of an Event of Default, any amounts of
                    principal prepaid or repaid by the Borrowers or
                    otherwise realized pursuant to any Security Document
                    shall be applied on a pro rata basis in accordance
                    with the percentages of the Lenders set forth in
                    subsection (a) above.  Any funds provided by a Funding
                    Lender pursuant to clauses (i) and (ii) above shall be
                    deemed to be a Revolving Line of Credit advance made
                    by such Lender to the Borrowers, and the Borrowers
                    shall be obligated to repay such advances pursuant to
                    the terms hereof.  In furtherance of the foregoing,
                    any purchase of assets pursuant to clause (ii) above
                    shall be made on behalf of Lime, and Lime shall be the
                    legal and beneficial owner of such assets.
     
                    (d)  In connection with any advances made by
                    the Funding Lenders pursuant to subsection (c) above,
                    the Companies shall execute such agreements, documents
                    and instruments (including, without limitation,
                    additional promissory notes), and take such further
                    actions, as any Funding Lender may reasonably request.
     
                    (e)  Notwithstanding anything to the contrary
                    contained herein, in order to effect the cure of any
                    default pursuant to Article 6 of the Project
                    Intercreditor Agreement, the Lenders shall have the
                    right (but not the obligation) to advance funds on
                    behalf of the Borrowers and to make any payments
                    directly to any Persons (other than the Borrowers) to
                    the extent necessary to cure such default.
     
               (ii)      Section 9.2 is amended in its entirety to read
               as follows:
     
                    "SECTION 9.2.  Manner of Revolving Line of
                    Credit Participation.  Unless otherwise specifically
                    provided in this Agreement, Agent shall receive from
                    Borrowers at least three business days', with respect
                    to Eurodollar Rate Loans, and one business day, with
                    respect to Base Rate Loans, prior written, telex,
                    telecopier or telegraphic notice of Borrowers'
                    intention to borrow hereunder, specifying the date,
                    the total amount of the loan that Borrowers request
                    under this Agreement, the type of loan and if a
                    Eurodollar Rate Loan, the Interest Period therefor. 
                    Upon receipt of such request from Borrowers, Agent
                    shall forthwith give Lenders (excluding itself if
                    Agent is also a Lender) telex, telecopier or
                    telegraphic notice of Borrower's request and shall
                    specify the amount of each such Lender's proposed
                    participation in the loan based on the information
                    each Lender has furnished Agent with respect to the
                    outstanding Revolving Line of Credit loans made by
                    each Lender and the outstanding Letters of Credit
                    applicable to each Lender.  Unless Lenders correct
                    said information prior to funding, which correction
                    shall be confirmed in writing by such Lender to Agent,
                    the Lenders shall deposit such amount, or cause such
                    amount to be deposited, with Agent in lawful money of
                    the United States of America in immediately available
                    funds by 11:00 A.M. (Central time) on the date of the
                    proposed loan by wire transfer to Agent in the case of
                    each Lender that is not Agent, and by deposit with
                    Agent in immediately available funds in the case of a
                    Lender that is also the Agent, and Agent shall
                    thereafter deposit in Borrowers' or DNRC's account or
                    accounts at Agent the requested funds by 11:30 A.M.
                    (Central time) on the date of the proposed loan."
     
               (iii)     Article IX is further amended by adding
               the following new Sections 9.3 and 9.4 at the end thereof.
     
                    SECTION 9.3.  Interest.  (a)  Each Borrower
                    shall, and hereby jointly and severally agrees to, pay
                    interest on the unpaid principal amount of each loan
                    from the date of such loan until such principal is
                    paid in full at the applicable rate set forth below.
     
                    (b)  Rate of Interest.  All loans shall bear
                    interest on the unpaid principal amount thereof from
                    the date such loans are made until paid in full,
                    except as otherwise provided in Section 9.3(e), as
                    follows:
     
                         (i)  If a Eurodollar Rate Loan, at a rate
                         per annum equal to the sum of (a) the Eurodollar
                         Rate determined for the applicable Interest
                         Period plus (b) the Interest Rate Margin; and
     
                         (ii) If a Base Rate Loan, at a rate per
                         annum equal to the sum of (A) the Base Rate plus
                         (B) the Interest Rate Margin.
     
               The applicable basis for determining the rate of
                    interest on the loans shall be selected at the time a
                    borrowing notice or a conversion/continuation notice,
                    as contemplated by subsection (d) below, is delivered
                    by the Borrowers to the Agent.  If on any day any loan
                    is outstanding with respect to which notice has not
                    been timely delivered to the Agent in accordance with
                    the terms of this Agreement specifying the basis for
                    determining the rate of interest on that day, then for
                    that day that loan shall be deemed to be a Base Rate
                    Loan.
     
                    (c)  Interest Payments.
     
                         (i)  Interest accrued on each Base Rate
                         Loan shall be payable in arrears (A) on each
                         Interest Payment Date applicable to such Loan,
                         (B) upon the prepayment thereof in full or in
                         part, (C) upon conversion thereof to a
                         Eurodollar Rate Loan, and (D) if not theretofore
                         paid in full, at maturity (whether by
                         acceleration or otherwise) of such Base Rate
                         Loan.
     
                         (ii) Interest accrued on each Eurodollar
                         Rate Loan shall be payable in arrears (A) on
                         each Interest Payment Date applicable to such
                         Loan, (B) upon the payment or prepayment thereof
                         in full or in part, and (C) if not theretofore
                         paid in full, at maturity (whether by

                    (d)  Conversion or Continuation.
     
                         (i)  The Borrowers shall have the option
                         (A) to convert at any time (1) all or any part
                         of outstanding Base Rate Loans to Eurodollar
                         Rate Loans or (2) all or any part of Eurodollar
                         Rate Loans to Base Rate Loans; or (B) to
                         continue all or any part of outstanding
                         Eurodollar Rate Loans, having Interest Periods
                         which expire on the same date as Eurodollar Rate
                         Loans, and the succeeding Interest Period of
                         such continued Loans shall commence on such
                         expiration date; provided, however, (I) no
                         portion of any such outstanding Loan may be
                         continued as (and shall be immediately converted
                         into a Base Rate Loan), or be converted into, a
                         Eurodollar Rate Loan (x) if the continuation of,
                         or the conversion into, would violate any of the
                         provisions of Section 9.4 or (y) if an Event of
                         Default has occurred and is continuing, and
                         (II) if the option set forth in clause (B) of
                         this Section is not exercised, in accordance
                         with the terms of this Section 9.3, in respect
                         of a Eurodollar Rate Loan, such Eurodollar Rate
                         Loan shall convert automatically into a Base
                         Rate Loan on the final date of the applicable
                         Interest Period.
     
                         (ii) To convert or continue a loan, the
                         Borrowers shall deliver a written notice to the
                         Agent at least three business days in advance of
                         the proposed conversion/continuation date.  Upon
                         receipt of such request from Borrowers, the
                         Agent shall forthwith give such notice to each
                         Lender.  Such notice shall specify the proposed
                         conversion/continuation date (which shall be a
                         business day), the principal amount to be
                         converted/continued, whether such borrowing

                    SECTION 9.4.  Special Provisions Governing

                    Rate Loans:
     
                    (a)  Determination of Interest Period.  The
                    period between the date on which each Eurodollar Rate
                    Loan is made and the date of payment in full of such
                    Loan shall be divided into successive periods, each
                    such period being an "Interest Period" for such Loan. 
                    The initial Interest Period for each Loan shall begin
                    on the date of such Loan and end on the last day of
                    such period as selected by the Borrowers, and
                    thereafter, each subsequent Interest Period for such
                    Loan shall begin on the last day of the immediately
                    preceding Interest Period for such Loan and end on the
                    last day of such period as selected by the Borrowers. 
                    The duration of each such Interest Period for each
                    Eurodollar Rate Loan shall be one, two or three
                    months, provided, however, that:
     
                         (i)  the duration of any Interest Period
                         for any Loan that commences before the repayment
                         date for such Loan and otherwise ends after such
                         repayment date shall end on such repayment date;
     
                         (ii) In the case of immediately
                         successive Interest Periods applicable to a
                         borrowing of Eurodollar Rate Loans, each
                         successive Interest Period shall commence on the
                         day on which the next preceding Interest Period
                         expires;
     
                         (iii)     If any Interest Period would
                         otherwise expire on a day which is not a
                         business day, such Interest Period shall be
                         extended to expire on the next succeeding
                         business day unless such next succeeding
                         business day would fall in the next calendar
                         month, in which case such Interest Period shall
                         end on the next preceding Business Day;
     
                         (iv) Borrowers may not select an Interest
                         Period as to any Eurodollar Rate Loan if such
                         Interest Period terminates later than the
                         Maturity Date; and
     
                         (v)  There shall be no more than ten
                         Interest Periods in effect at any one time.
     
                    (b)  Interest Rate Unascertainable, Inadequate
                    or Unfair.  In the event that at least one business
                    day before the commencement of an Interest Period, a
                    Lender determines that adequate and fair means do not
                    exist for ascertaining the applicable interest rates
                    by reference to which the Eurodollar Rate, then being
                    determined is to be fixed, then such Lender shall
                    forthwith give notice thereof to the Borrowers and the
                    Agent, whereupon (until such Lender notifies the
                    Borrowers and the Agent that the circumstances giving
                    rise to such suspension no longer exist, which such
                    Lender shall do promptly after it determines that such
                    circumstances no longer exist) the right of all
                    Borrowers to elect to have loans from such Lender bear
                    interest based upon the Eurodollar Rate shall be
                    suspended and all outstanding Eurodollar Rate Loans
                    from such Lender shall be converted into Base Rate
                    Loans on the last day of the then current Interest
                    Period therefor, notwithstanding any prior election by
                    the Borrowers to the contrary.
     
                    (c)  Illegality.
     
                         (i)  If at any time a Lender determines
                         (which determination shall, absent manifest
                         error, be final and conclusive and binding upon
                         all parties) that the making or continuation of
                         any Eurodollar Rate Loan has become, as a result
                         of any event occurring after the date hereof (A)
                         unlawful or (B) impermissible by compliance by
                         such Lender with any law, governmental rule,
                         regulation or order of any governmental
                         authority (whether or not having the force of
                         law and whether or not failure to comply
                         therewith would be unlawful or would result in
                         costs or penalties), then such Lender may give
                         notice of that determination to the Agent and
                         the Borrowers.
     
                         (iii)     When notice is given by a Lender
                         under this Section, (A) the Borrowers' right to
                         request from such Lender and such Lender's
                         obligation, if any, to make Eurodollar Rate
                         Loans shall be immediately suspended, and such
                         Lender shall make a Base Rate Loan in lieu of
                         any requested Eurodollar Rate Loans (on which
                         such Base Rate Loan the interest and principal
                         shall be payable contemporaneously with the
                         related Eurodollar Rate Loans of the other
                         Lenders) and (B) if Eurodollar Rate Loans are
                         then outstanding, the Borrowers shall
                         immediately, or if permitted by applicable law,
                         no later than the last date permitted thereby,
                         upon at least one business day's prior notice to
                         such Lender, convert each such Loan into a Base
                         Rate Loan (on which such Base Rate Loan the
                         interest and principal shall be payable
                         contemporaneously with the related Eurodollar
                         Rate Loans of the other Lenders).
     
                         (iii)     If at any time after a Lender gives
                         notice under this Section, such Lender
                         determines that it may lawfully make Eurodollar
                         Rate Loans, such Lender shall promptly give
                         notice of that determination to the Borrowers
                         and the Agent.  The Borrowers' right to request,
                         and such Lender's obligation, if any, to make
                         Eurodollar Rate Loans shall thereupon be
                         restored.
     
                    (d)  Compensation.  In addition to all amounts
                    required to be paid by the Borrowers pursuant to
                    Section 9.3, the Borrowers shall jointly and severally
                    compensate each Lender, within thirty days of written
                    notice, for all losses, expenses and liabilities
                    (including, without limitation, any loss or expense
                    incurred by reason of the liquidation or reemployment
                    of deposits or other funds acquired by each such
                    Lender to fund or maintain such Lender's Eurodollar
                    Rate Loans to the Borrowers) which such Lender may
                    sustain (i) if for any reason not the fault of such
                    Lender, a loan, conversion into or continuation of
                    Eurodollar Rate Loans does not occur on a date
                    specified therefor in any notice given by the
                    Borrowers or a successive Interest Period does not
                    commence after notice therefor is given, or (ii) if
                    for any reason any Eurodollar Rate Loan is prepaid on
                    a date which is not the last day of the applicable
                    Interest Period, or (iii) as a consequence of a
                    required conversion of a Eurodollar Rate Loan to a
                    Base Rate Loan as a result of any of the events
                    indicated in Section 9.4, or (iv) as a consequence of
                    any failure by the Borrowers to repay Eurodollar Rate
                    Loans when required by the terms of this Agreement. 
                    Such Lender's written notice shall set forth in
                    reasonable detail the basis for such compensation and
                    shall be conclusive as to the amount of compensation
                    due to such Lender, absent manifest error.
     
                    (e)  Exhibits.  Exhibits A-1, A-2 and A-3 to
                    the Revolving Credit Agreement are deleted in their
                    entirety and Exhibits A-1, A-2 and A-3 attached hereto
                    are substituted therefor, respectively.
     
                    (f)  Amendments to Article XII.  Article XII
                    shall be amended by adding the following Section 12.3:

                         the Operative Documents.

               will deliver in triplicate to each Lender (or any other holder
               of any Note or Notes) so long as such Lender (or holder) shall

                    each fiscal year, consolidating and consolidated

                    public accountants of recognized national standing
                    selected by such Dravo Party whose report shall be

                    (without exhibits) and all reports which it files with

                    financial officer of each such corporation;
     
                    (v)  promptly upon receipt thereof, a copy of
                    each other report submitted to such corporation or any
                    Subsidiary by independent accountants in connection with
                    any annual, interim or special audit made by them of the
                    books of such corporation or any Subsidiary;
     
                    (vi) upon the request of a holder of any Note,
                    provide such holder, and any qualified institutional
                    buyer designated by such holder, such financial and
                    other information as such holder may reasonably
                    determine to be necessary in order to permit compliance
                    with the information requirements of Rule 144A under the
                    Securities Act in connection with the resale of Notes,
                    except at such times as Dravo is subject to the
                    reporting requirements of section 13 or 15(d) of the
                    Exchange Act.  For the purpose of this clause (vi), the
                    term "qualified institutional buyer" shall have the
                    meaning specified in Rule 144A under the Securities Act;
     
                    (vii)     with reasonable promptness, such other
                    financial data as any Lender may reasonably request; and
     
                    (viii)     a report, delivered not less
                    frequently than once during each period of four
                    consecutive months, of the General Counsel of Dravo that
                    describes and evaluates all pending litigation against
                    any Dravo Party where the amount of potential loss could
                    exceed $5,000,000.  Each such report should include a
                    brief description of the events that have occurred in
                    such litigation since the date of the last report,
                    including, without limitation, the occurrence and/or
                    outcome of any motions for summary judgment, discovery
                    motions, substantive discovery responses, or motions for
                    final adjudication.  In addition, at the request of any
                    Lender, each Dravo Party shall, at its expense, provide
                    each Lender, and its outside counsel, an opportunity to
                    receive copies of all documentation received or prepared
                    in connection with any such litigation, and to discuss
                    the status thereof with the General Counsel of Dravo and
                    the outside counsel of any such Dravo Party handling
                    such matter.  Notwithstanding the foregoing, at no time
                    shall any Dravo Party or its counsel be required to make
                    any disclosure or provide any access to information
                    pursuant to this paragraph which would result in the
                    loss to such Dravo Party of any privilege against
                    disclosure generally recognized under law.
     
          Together with each delivery of financial statements required
     by clauses (i) and (ii) above, each of the Dravo Parties will
     deliver to each Lender (addressed to it) a Compliance Certificate,
     in the form of Exhibit O hereto, demonstrating (with computations in
     reasonable detail except to the extent specifically set forth in
     such financial statements) compliance by the Dravo Parties with
     Section 4.02(b), 5.01(a), (b), (c)(i), (c)(ii) and (d), and stating
     that there exists no Default or Event of Default, or, if any such
     Default or Event of Default exists, specifying the nature thereof,
     the period of existence thereof and what action such corporation
     proposes to take with respect thereto.
     
          Together with each delivery of financial statements required
     by clause (ii) above, each of the Dravo Parties will deliver to each
     Lender a certificate of said accountants stating that, in making the
     audit necessary to the certification of such financial statements
     they have obtained no knowledge of any Default or Event of Default,
     or, if any such Default or Event of Default exists, specifying the
     nature and period of existence thereof.  Such accountants, however,
     shall not be liable to anyone by reason of their failure to obtain
     knowledge of any Default or Event of Default which would not be
     disclosed in the course of an audit conducted in accordance with
     generally accepted auditing standards.  Each Lender is hereby
     authorized to deliver a copy of any financial statement delivered to
     such Lender pursuant to this Section 4.01(a) to any regulatory body
     having jurisdiction over such Lender.
     
          Each of the Dravo Parties also covenants that forthwith upon
     the chief executive officer, principal financial officer or
     principal accounting officer of such Dravo Party obtaining knowledge
     of:
     
               (i)  a Default or an Event of Default;
     
               (ii) a material adverse change in the financial
               condition, business or operations of such Dravo Party and its
               Subsidiaries, taken as a whole;
     
               (iii)     the institution of legal proceedings against such
               Dravo Party and/or any Subsidiary, which has a reasonable
               possibility of materially adversely affecting the financial
               condition, business or operations of such Dravo Party and its
               Subsidiaries, taken as a whole or which in any manner draws
               into question the validity of or has a reasonable possibility
               of impairing the ability of such Dravo Party to perform its
               obligations under this Agreement or any of the other Operative
               Documents to which it is a party;
     
               (iv) the occurrence of any default under any agreement
               or note evidencing borrowed money;
     
               (v)  the occurrence of any other event that reasonably
               could impair the ability of such Dravo Party to meet its
               obligations hereunder or under any other Operative Document;
               or
     
               (vi) any (A) Environmental Liabilities, (B) pending,
               threatened or anticipated Environmental Proceedings, (C)
               Environmental Notices, (D) Environmental Judgments and Orders,
               or (E) Environmental Releases at, on, in, under or in any way
               materially affecting the Properties;
     
     such Dravo Party will deliver to the Lenders an Officer's
     Certificate specifying the nature and period of existence thereof
     and what action such Dravo Party has taken, is taking or proposes to
     take with respect thereto.
     
          (b)  Inspection of Property.  Each of the Dravo Parties
     covenants that, so long as a Lender shall hold any Note or Notes,
     any of them will permit any person designated by such Lender in
     writing, at the expense of such Dravo Party, to visit and inspect
     any of the properties of any such Dravo Party and its Subsidiaries,
     to examine the corporate books and financial records of any such
     Dravo Party and its Subsidiaries and make copies thereof or extracts
     therefrom and to discuss the affairs, finances and accounts of any
     such corporation with the principal officers and independent public
     accountants of such corporation, all at such reasonable times and
     upon such reasonable notice and as often as such Lender may
     reasonably request.
     
          (c)  Secure Notes Equally.  Each of the Dravo Parties
     covenants that, if any of the Dravo Parties creates or assumes any
     Lien upon any of its property or assets, whether now owned or
     hereafter acquired, other than Liens excepted by the provisions of
     Section 5.03(a)(i) (unless prior written consent to the creation or
     assumption thereof shall have been obtained pursuant to Section
     8.02), it will make or cause to be made effective provisions whereby
     the Notes then outstanding will be further secured by such Lien
     equally and ratably with any and all other debt thereby secured as
     long as such other debt shall be so secured.
     
          (d)  Guaranteed Obligations.  Each of the Dravo Parties
     covenants that if, at any time after the date hereof, it or any of
     its Subsidiaries incurs or permits to exist any Debt or other
     obligation guaranteed or collateralized in any other manner by any
     Person, it will simultaneously cause such Person to execute and
     deliver to each holder of any Note a guaranty agreement in form and
     substance satisfactory to such holder guaranteeing payment of the
     principal amount of the Notes and any premium and interest thereon,
     which bears the same ratio to the total unpaid principal amount of
     the Notes as the amount of such other obligation which is guaranteed
     bears to the total unpaid principal amount of such other obligation,
     or if such other obligation is collateralized, to collateralize the
     Notes equally and ratably with such other obligation.
     
          (e)  Maintenance of Insurance.  Each of the Dravo Parties
     will maintain, and will cause each of its Subsidiaries to maintain,
     with responsible insurers, insurance with respect to its properties
     and business against such casualties and contingencies (including
     public liability, larceny, embezzlement or other criminal
     misappropriation) and in such amounts as is customary in the case of
     similarly situated corporations engaged in the same or similar
     businesses, and, if requested in writing by a Lender, together with
     each delivery of financial statements under clause (ii) of Section
     4.01(a) each of the Dravo Parties will deliver an Officer's
     Certificate specifying the details of such insurance in effect.

     will do or cause to be done all things necessary to preserve, renew
     and keep in full force and effect the corporate existence of such
     Dravo Party and its Subsidiaries (other than Discontinued
     Subsidiaries) and comply in all material respects with all laws and
     regulations (including, without limitation, laws and regulations
     relating to equal employment opportunity and employee safety)
     applicable to it and its Subsidiaries (other than Discontinued
     Subsidiaries), the failure with which to comply would have a
     reasonable possibility of materially adversely affecting the
     business, operations or financial condition of such Dravo Party and
     its Subsidiaries (other than Discontinued Subsidiaries), taken as a
     whole; at all times maintain, preserve and protect all material
     intellectual property of such Dravo Party and its Subsidiaries
     (other than Discontinued Subsidiaries), and preserve all the
     remainder of its material property used or useful in the conduct of
     its business and keep the same in good repair, working order and
     condition.
     
          (h)  Compliance with Environmental Laws.  Each of the Dravo
     Parties will, and will cause each of its Subsidiaries to, comply in
     a timely fashion with, or operate pursuant to valid waivers of the
     provisions of, all Environmental Requirements including, without
     limitation, the emission of wastewater effluent, solid and hazardous
     waste and air pollution, and establishing general environmental
     conditions, together with any other applicable requirements for
     conducting, on a timely basis, periodic tests and monitoring for
     contamination of ground water, surface water, air and land and for
     biological toxicity of the aforesaid, and diligently comply with the
     regulations (except to the extent such regulations are waived by
     appropriate governmental authorities) of the Environmental
     Protection Agency or other relevant federal, state or local
     governmental authority, except where the failure to do so would not
     have a reasonable possibility of materially adversely affecting the
     business, operations or financial condition of such Dravo Party and
     its Subsidiaries, taken as a whole.
     
          (i)  Appraisals.  From time to time, a Lender or Lenders may
     commission or obtain an appraisal of the property covered by the
     Lime Mortgages by an appraiser satisfactory to such Lender or
     Lenders and in compliance with the standards of the Member Appraisal
     Institute and may commission or obtain such other valuations as a
     Lender or Lenders may reasonably require from time to time.
     
          (j)  Additional Mortgage Conveyances.  Upon the acquisition
     by any Dravo Party of any additional properties located adjacent to,
     or used or usable in connection with the operations of the Dravo
     Parties on, the property covered by the Lime Mortgages or the

               clause; and
     
               (ii) for each of Dravo's fiscal quarters commencing

     to Dravo with respect to or on account of the Dravo affiliated
     group's consolidated federal income tax liability ("Dravo
     Consolidated Tax Liability") in excess of the amount of such tax
     liability that would have been apportioned to such Company had
     Section 1552(a)(1) of the Code and Treasury Regulation
     31.155201(a)(1) been used to determine each such Company's tax
     liability.  In addition, no payment shall be made by any Other
     Subsidiary or any Subsidiary of the Companies to Dravo with respect
     to or on account of the Dravo Consolidated Tax Liability.  No
     intercompany account or indebtedness owing from the Companies or
     their Subsidiaries shall be created in connection with any tax

                    any Lien upon any of its property or assets, whether now
                    owned or hereafter acquired (whether or not provision is

                         conditions, operations or prospects of such
                         corporation in the event that the underlying
                         obligations for such Liens were not paid,

                         of its business or the ownership of its property
                         and assets which were not incurred in connection
                         with the borrowing of money or the obtaining of
                         advances or credit, and which do not in the
                         aggregate materially detract from the value of
                         its property or assets or materially impair the
                         use thereof in the operation of its business,

                         consolidation or otherwise, whether or not

     shall be in addition to every other remedy conferred herein or now
     hereafter existing at law or in equity or by statute or otherwise.

                        Dravo Corporation
                   Incentive Compensation Plan
                     (Revised December 1995)
                                
 The  Dravo Corporation Incentive Compensation Plan provides
 senior managers and other key employees the opportunity  to
 earn  incentive income each year by achieving or surpassing
 predetermined, preapproved objectives.
 
 Objectives
 
 The objectives of the Incentive Compensation Plan are to:
 
  1.   Promote individual ownership and accountability in the
     ongoing success of the corporation, while focusing team efforts
     on overall corporate earnings objectives.
  
  2.   Encourage and reward management achievements that contribute
     to the value of the corporation.
  
  3.   Communicate key corporate and divisional priorities through
     the plan.
  
  4.   Provide senior managers and other key employees with a
     competitive compensation opportunity.
  
 Plan Summary
 
 The Dravo Corporation Incentive Compensation Plan (ICP)  is
 a   target   incentive   plan   that   provides   for   the
 establishment  of  target, threshold and optimum  incentive
 awards    based    upon   performance   against    specific
 predetermined  performance  objectives.    Prior   to   the
 beginning of each plan year, target, threshold and  optimum
 performance  levels will be established  and  approved  for
 Corporate  and  Dravo Lime divisional  performance.   Those
 employees  who  function across divisional  locations  will
 have  a  single Corporate component (100%).  Those who  are
 assigned to an individual operating unit will have  both  a
 Corporate   component  (70%)  and  a  Divisional  component
 (30%).
 
 At  the  beginning  of each year each participant  will  be
 provided  with a Participant's Guide, which will give  them
 an  overview of the plan and specify their target award and
 award components.
 
 Shareholder Protection Provisions
 
 To  assure  that  ICP  awards  are  related  to  acceptable
 corporate  earnings,  the following shareholder  protection
 provisions will apply:
 
 In  developing  each year's Plan, the sum of all  projected
 ICP  awards  will not be allowed to exceed 8% of  projected
 after  tax  earnings  from continuing operations.   If  the
 total  of  all  projected  ICP awards  exceeds  8%  of  the
 projected  after  tax earnings from continuing  operations,
 then   either  the  number  of  participants   and/or   the
 individual target percentages are to be reduced  until  the
 total is 8% or less.
 
    If  the  Corporation  fails  to  achieve  threshold  EPS
 performance,  no incentive awards will be  made  under  the
 plan at any level for any component for any participant.
 
 Eligibility
 
 Participation in the plan may be extended to Corporate  and
 Dravo  Lime senior managers and other key employees.  Prior
 to  the  beginning of each plan year, eligible participants
 are  recommended  by  the  President  and  Chief  Executive
 Officer  (CEO)  and approved by the Compensation  Committee
 of the Board of Directors (Committee).
 
 Individual Target Awards
 
 Target  awards  are  established so as to  pay  competitive
 levels  of  incentive compensation for achievement  of  the
 targeted  performance levels. Target awards  will  equal  a
 specified  percentage of the Midpoint  salary  of  the  job
 grade  for  each  participant in the plan. Percentages  may
 vary  within the job grade based on accountability  of  the
 job   as  recommended  by  the  CEO  and  approved  by  the
 Committee each year.
 
 Range of Awards
 
 The  target  award  will be paid at the targeted  level  of
 performance on any component of the plan.
 
 The  threshold  award, equal to 50 percent  of  the  target
 award,  will  be paid at the threshold level of performance
 on  any  component  of the plan.  If performance  fails  to
 meet  the  threshold,  no  award  will  be  made  for  that
 component.
 
 The  optimum  award,  equal to 150 percent  of  the  target
 award,  will be paid for performance equal to or above  the
 optimum level of performance on any component of the Plan.
 
 Allocation of Awards Among Components
 
 Awards  will  be  allocated to reflect  the  organizational
 level  where  the  participant has the  greatest  level  of
 influence on business results.
 
 For  all  participants awards the greatest weight  will  be
 given  to corporate performance.  For participants assigned
 to  a specific operating division, a portion of their award
 will  be  allocated  to  reflect the performance  of  their
 respective division.
 
 Corporate Component
 
 All   participants  at  the  Corporate  level,  and   those
 participants  who are not assigned to a specific  operating
 division  will  receive  100% of their  award  through  the
 Corporate  component.  Employees  who  are  assigned  to  a
 specific  operating division location will receive  70%  of
 their award through the Corporate component.
 
 The  performance  measure for the  Corporate  component  is
 Earnings  Per Share (EPS) from continuing operations.   The
 CEO   will   recommend  to  the  Committee   for   approval
 threshold,  target  and optimum levels of  EPS  performance
 for the Plan Year for use in determining awards.
 
 Performance at the threshold level will result in an  award
 of  50%  of the target for this component.   At the  target
 level of performance, the target award will be made and  at
 the  optimum  level, the optimum award of  150%  of  target
 will  be  made.  For intermediate results, awards  will  be
 interpolated.
 
 The  Corporate component may be adjusted, with the approval
 of  the  Committee, to reflect the impact of  extraordinary
 events on Corporate EPS.
 
 Divisional Component
 
 Participants employed in the various operating divisions  -
 -  Black River, Maysville and Longview -- will receive  30%
 of  their  awards  through a Divisional component  that  is
 based   upon  the  results  attained  by  their  respective
 operating division.
 
 The  performance  measure for the Divisional  component  is
 earnings  before interest and taxes (EBIT).  The  CEO  will
 recommend  to the Committee for approval threshold,  target
 and  optimum levels of EBIT performance for each  operating
 division for the plan year for use in determining awards.
 
 The  relationship of actual results to awards is determined
 in  the  same  way  as described above  for  the  Corporate
 component.
 
 The   Divisional  component  may  be  adjusted,  with   the
 approval  of  the  Committee,  to  reflect  the  impact  of
 extraordinary events on an operating division's EBIT.
 
 Payment of Incentive in Dravo Corporate Stock
 
 For  participants in job grade level 24 and above having  a
 target  percentage of 15% or more, the  ICP  award  may  be
 paid  in  a  combination  of cash and  stock.  The  maximum
 percentage  of stock will be specified for each  applicable
 job  grade.  The actual amount of the award paid  in  stock
 will  be  recommended  by  the  CEO  and  approved  by  the
 Committee.  Such  stock  award  will  be  a  grant  to  the
 employee, and it is expected that the employee will  retain
 ownership of the stock while in a management position  with
 the  Corporation. The amount of incentive award to be  used
 for  stock  will be determined by first tax  adjusting  the
 employee's  total  incentive award and  then  applying  the
 percentage  to  that tax adjusted amount.   The  number  of
 shares  of  stock  awarded  will be  calculated  using  the
 average between the high and low price of the stock on  the
 date the award is made, and using the full market value  of
 the stock.
 
 Partial Year Payments
 
 A  new employee, hired into an approved ICP position,  will
 have   his   target  percentage  and  component  allocation
 established  in  accordance with the Plan.  The  employee's
 award will be calculated at the end of the year along  with
 other  participants, but the award will be  prorated  based
 on the number of months of employment.
 
 Terminations
 
 Employees who terminate from the company prior to  December
 31  of the plan year for any reason, with the exception  of
 lay   off,   change  of  control  termination,  retirement,
 disability,   or   death,  will  forfeit  their   incentive
 compensation  for  that  year.   Employees  who  leave  the
 company  prior  to December 31 due to lay  off,  change  of
 control  termination,  retirement, disability,  or  in  the
 event  of  death,  will  receive a prorated  incentive  for
 those  months  actually worked.  Employees  who  leave  the
 company  after  December 31 will be paid  their  award,  if
 any, when other ICP payments are distributed.
 
 Promotions
 
 Employees  promoted  into an ICP position  from  a  non-ICP
 position,  or  employees who are promoted into  a  position
 having  a  higher  salary grade, target  percentage  and/or
 different  component  allocation,  will  receive  an  award
 prorated  for  the  number  of  months  spent  in  the  new
 position.   If  an  ICP  award has  been  earned  in  their
 previous  position,  that award will  be  prorated  by  the
 number of months spent in the previous position.
 
 Plan Administration
 
 The  plan is administered by the Compensation Committee  of
 the  Board  of  Directors.  The Committee is authorized  to
 interpret  the plan, to establish and amend rules  for  its
 administration  and  to make discretionary  adjustments  in
 awards due to extraordinary events.
 
 Recommendations as to the operation of the  plan,  eligible
 participants,  target  percentages, component  allocations,
 type  (cash and/or restricted stock) and amount of  awards,
 performance criteria, and extraordinary adjustments may  be
 made to the Committee by the CEO.

Options.

     Section 4.  Duration.  All awards granted under this Plan must

the Committee.  Subject to the provisions of the Plan and to
policies determined by the Board of Directors, the Committee is
authorized to interpret the Plan, adopt such rules and regulations
and take such action in the administration of the Plan as it shall

     Section 6.  Authority of the Committee.  Subject to the
provisions of the Plan, the Committee shall have full and final

be awarded and the number of shares to be covered by each option or
SAR.  The Committee may determine that options or SARs shall be
exercisable in one or more installments during the term of the
option or SAR and the right to exercise may be cumulative as
determined by the Committee.

     Section 7.  Eligibility.

     
     (a)  Officers and other key employees of the Corporation (including
officers and other employees who are directors of the Corporation)
who, in the opinion of the Committee, are mainly responsible for
the continued growth and development and future financial success
of the business shall be eligible to participate in the Plan.  The
Committee shall, in its sole discretion, from time to time select
from such eligible persons those to whom options or SARs shall be
granted and determine the type of option and the number of shares
to be included in such option or SAR.  No officer or other employee
shall have any right to receive an option or SAR except as the
Committee in its discretion shall determine.

     
     (b)  Non-employee directors shall be eligible to receive awards
only pursuant to and in accordance with Section 12 of the Plan.

     Section 8.  Shares Subject to the Plan.  The total number of
shares of Common Stock which may be issued or on which SARs may be
calculated pursuant to the Plan shall be One Million (1,000,000)
shares of Common Stock (subject to adjustment as provided in
Section 13), which may be either authorized and unissued shares or
shares held in the treasury of the Corporation, and which shares
are hereby reserved for the purposes of the Plan.  To the extent
that options or SARs granted under the Plan shall expire or
terminate without being exercised, shares covered thereby shall
remain available for purposes of the Plan.  To the extent that
options are terminated by reason of the exercise of a related SAR,
the shares covered by such option shall not be available for grant
of further options or SARs under the Plan.

     Section 9.  Terms of Options and SARs Awarded to Employee
Participants.  Each option and SAR granted to an Employee
Participant under the Plan shall be evidenced by a stock option or
Stock Appreciation Rights agreement between the Corporation and the
grantee and shall be subject to the following terms and conditions:

     
     (a)  Subject to adjustment as provided in Section 13 of the Plan,
the price at which each share covered by an option or SAR may be
purchased shall be determined in each case by the Committee but
shall not be less than the Fair Market Value thereof at the time
the option is granted.  If a grantee owns (or is deemed to own
under applicable provisions of the IRC and rules and regulations
promulgated thereunder) more than 10% of the combined voting power
of all classes of the stock of the Corporation (or any parent or
Subsidiary corporation of the Corporation) and an option granted to
such grantee is intended to qualify as an Incentive Stock Option,
the option price shall be not less than 110% of the Fair Market
Value of the shares covered by the option on the date the option is
granted.

     
     (b)  During the lifetime of the grantee, the option or SAR may be
exercised only by the grantee or by his or her guardian or legal
representative.  The option or SAR shall not be transferable by the
grantee otherwise than by will or by the laws of descent and
distribution.

     
     (c)  Except as otherwise provided herein, an option or SAR may be
exercised in whole at any time, or in part from time to time,
within such period or periods from the granting of the option or
SAR as may be determined by the Committee and set forth in the
stock option or Stock Appreciation Rights agreement (such period or
periods being hereinafter referred to as the exercise period),
provided that except as otherwise provided in Section 11 hereof,
options and SARS may not be exercisable prior to one (1) year from
the date of grant and the exercise period shall not exceed ten
years.  Notwithstanding the foregoing:

          
          i)   An option or SAR may be exercised during the lifetime of the
               grantee only while he or she is in the employ of the Corporation 
               or within three (3) months following termination of employment 
               and only to the extent that the option or SAR would be exercis-
               able by the grantee at the time of termination.  Notwithstanding
               the foregoing, in the event that termination is by reason of
               Retirement, permanent disability or death, the option or SAR may
               be exercised in whole or in part until the earlier of (1) the
               expiration of the term of the option or SAR, or (2) five years
               after said termination. In the event the grantee dies within five
               years following Retirement or termination by reason of permanent
               disability,his or her estate may exercise the option or SAR until
               the earlier of(1)the expiration of the term of the option or SAR,
               or(2)five years after said employee's retirement or termination.
               For this purpose, the grantee may designate to the Committee the
               person or persons to whom his or her rights under the option or
               SAR shall pass in the event of his or her death;
               
          
          ii)  The option or SAR may not be exercised for more shares
               (subject to adjustment as provided in Section 13) after the
               termination of the grantee's employment or his or her death than
               the grantee was entitled to acquire thereunder at the time of the
               termination of the grantee's employment or his or her death;
               
          
          iii) If a grantee owns (or is deemed to own under applicable
               provisions of the IRC and rules and regulations promulgated
               thereunder) more than 10% of the combined voting power of all
               classes of the stock of the Corporation (or any parent or
               Subsidiary corporation of the Corporation) and an option granted
               to such grantee is intended to qualify as an Incentive Stock
               Option, the option by its terms may not be exercisable after the
               expiration of five years from the date such option is granted.
               
     
     (d)  Subject to the limitations herein set forth, the option or SAR
may be exercised in whole or in part from time to time by written
request made to the Corporation in the manner determined from time
to time by the Committee.  Payment in full for the number of shares
purchased upon exercise of an option shall be made to the
Corporation at the time of each exercise.  Payment may be made in
cash or by delivering to the Corporation shares of Common Stock of
the Corporation or any combination of such shares and cash, having
in any case an aggregate Fair Market Value equal to the option
price of the shares being purchased pursuant to the exercise of the
option, or by delivering to the Corporation a notice of exercise
with an irrevocable direction to a registered broker-dealer under
the Securities Exchange Act of 1934, as amended, to sell a
sufficient portion of the shares and deliver the sale proceeds
directly to the Corporation to pay the exercise price.

     
     (e)  No grantee may be granted Incentive Stock Options to purchase
Common Stock of the Corporation in any year to the extent that the
aggregate Fair Market Value of the Common Stock, determined at the
time of grant, with respect to which Incentive Stock Options are
exercisable for the first time by the grantee (under all plans of
the Corporation) exceeds $100,000 during such calendar year.  If
any option designated as an Incentive Stock Option either alone or
in conjunction with any other option or options exceeds the
foregoing limitation, options in excess of such limitation shall
automatically be reclassified as Non-Statutory Stock Options by
whole number of shares, with later granted options being so
reclassified first.

     
     (f)  The Committee, in its discretion, may provide that any option
intended to be an Incentive Stock Option shall also be subject to
such additional or more restrictive terms and conditions as may,
from time to time, be required to constitute such option an
Incentive Stock Option under the provisions of Section 422 of the
IRC.  This Plan shall be construed in a manner consistent with
Section 422 of the IRC and Treasury Regulations promulgated or
proposed thereunder.

     
     (g)  The Committee may include such other terms and conditions not
inconsistent with the foregoing as the Committee shall approve.
Without limiting the generality of the preceding sentence, the
Committee shall be authorized to impose conditions to the exercise
of options relating to the performance of the Corporation or any
Subsidiary or of grantee(s) or any combination of the foregoing.
The Committee shall, in its sole judgment, determine whether such
conditions have been fulfilled and may require that the Committee
receive from the Corporation a written certificate as to the
fulfillment of such conditions before shares are issued and sold
pursuant to options or SARs which have been exercised.

     Section 10.  Stock Appreciation Rights.

     
     (a)  The Committee, in its discretion, may provide that any option
granted to an Employee Participant includes a tandem Stock
Appreciation Right; provided, however, that a grantee may elect to
exercise the tandem Stock Appreciation Right with respect to an
Incentive Stock Option only when the Fair Market Value of the
shares subject to such option exceeds the option price.  The right
to elect such Stock Appreciation Right granted in tandem with an
option shall entitle the grantee to receive an amount equal to the
excess of the Fair Market Value of one share of Common Stock over
the option price per share, multiplied times the number of shares
as to which the option, or portion thereof, is surrendered.  This
amount shall be paid in cash or in Common Stock, or in such
combination of Common Stock and cash as the Committee shall from
time to time determine, having in any case an aggregate Fair Market
Value equal to the amount required to be paid.  All SARs granted in
tandem with options shall be subject to the same terms and
conditions as the related option.

     
     (b)  The Committee, in its discretion, may grant Stock Appreciation
Rights which do not relate to an option.  Such "stand-alone" SARs
shall be governed by the provisions of the Plan relating to Non-
Statutory Stock Options and by the terms of a Stock Appreciation
Rights Agreement between the Corporation and the grantee setting
forth the number of shares as to which such stand-alone SARs are
granted and such other terms and conditions as the Committee may
determine.  Upon exercise of a stand-alone SAR, the grantee shall
be entitled to receive an amount equal to the excess of the Fair
Market Value of one share of Common Stock determined at the date of
exercise over the Fair Market Value of one share of Common Stock
determined at the date of grant, multiplied times the number of
shares as to which the SAR was granted.  This amount shall be paid
in cash or in Common Stock, or in such combination of Common Stock
and cash as the Committee shall from time to time determine, having
in any case an aggregate Fair Market Value equal to the amount
required to be paid.

     Section 11.  Acceleration of Right of Exercise.  Except with
respect to options granted to non-employee directors, any option or
SAR granted hereunder shall become immediately exercisable in the
event of a Change in Control unless otherwise provided by the
Committee at the time of grant.

     Section 12.  Provisions Applicable to Non-employee Directors
Options.

     
     (a)  Each non-employee director shall automatically receive a Non-
Statutory Stock Option to purchase 1,500 shares of Common Stock on
the first Friday following the Corporation's Annual Meeting of
Shareholders at which such director is elected to serve and on the
first Friday following each Annual Meeting of Shareholders
thereafter so long as such director continues as a member of the
Board.  Any non-employee director whose initial term commenced
prior to the effective date of this Plan who is serving as a
director on such effective date shall automatically receive a Non-
Statutory Stock Option to purchase 1500 shares of common stock on
the first Friday following each Annual Meeting of Shareholders so
long as such director continues as a member of the Board.

     
     (b)  Each option granted to a non-employee director shall be
evidenced by written documentation containing its terms and
conditions.

     
     (c)  The exercise price for options granted to non-employee
directors shall not be less than 100% of the Fair Market Value of
the underlying shares of Common Stock on the date the stock option
is granted.

(d)  Stock options granted to non-employee directors under this
Plan shall become exercisable one year after the date of grant,
shall expire ten years after the date of grant and shall not be
transferable otherwise than by will or by the laws of descent and
distribution.
     
     (e)  Payment may be made in cash or by delivering to the
Corporation shares of Common Stock of the Corporation or any
combination of such shares and cash, having in any case an
aggregate Fair Market Value equal to the option price of the shares
being purchased pursuant to the exercise of the option or by
delivering to the Corporation a notice of exercise with an
irrevocable direction to a registered broker-dealer under the
Securities Exchange Act of 1934, as amended, to sell a sufficient
portion of the shares and deliver the sale proceeds directly to the
Corporation to pay the exercise price.

     
     (f)  Upon cessation of service of a non-employee director (other
than for death), only those options exercisable at the date of
cessation of service shall continue to be exercisable by the
grantee.  Such options must be exercised within 90 days of
cessation of service, but in no event after the expiration of the
option period.

     
     (g)  Upon the death of a non-employee director, those options which
were exercisable on the date of death may be exercised within 36
months from the date of death, but in no event after the expiration
of the option period, by the grantee's estate.  For this purpose,
the grantee may designate to the Committee the person or persons to
whom his or her rights under the option shall pass in the event of
his death.

     Section 13.  Adjustment of Number and Price of Shares.

     
     (a)  In the event that a dividend shall be declared upon the Common
Stock of the Corporation payable in shares of said stock, the
number of shares of Common Stock covered by each outstanding option
and SAR and the number of shares available for issuance pursuant to
the Plan but not covered by options or SARs shall be adjusted by
adding thereto the number of shares which would have been
distributable thereon if such shares had been outstanding on the
date fixed for determining the shareholders entitled to receive
such stock dividend.

     
     (b)  In the event that the outstanding shares of Common Stock of
the Corporation shall be changed into or exchanged for a different
number or kind of shares of stock or other securities of the
Corporation or of another corporation, whether through
reorganization, recapitalization, stock split-up, combination of
shares, merger or consolidation, then there shall be substituted
for the shares of Common Stock covered by each outstanding option
and SAR and for the shares available for issuance pursuant to the
Plan but not covered by an option or SAR, the number and kind of
shares of stock or other securities which would have been
substituted therefor if such shares had been outstanding on the
date fixed for determining the shareholders entitled to receive
such changed or substituted stock, SAR or other securities.

     
     (c)  In the event there shall be any change, other than specified
above in this Section 13, in the number or kind of outstanding
shares of Common Stock of the Corporation or of any stock or other
securities into which such Common Stock shall be changed or for
which it shall have been exchanged, then if the Committee shall
determine, in its discretion, that such change equitably requires
an adjustment in the number or kind of shares covered by
outstanding options or SARs or which are available for issuance
pursuant to the Plan but not covered by options or SARs, such
adjustment shall be made by the Committee and shall be effective
and binding for all purposes of the Plan and on each outstanding
stock option and SAR agreement.

(d)  In the event that, by reason of a corporate merger,
consolidation, acquisition of property or stock, separation,
reorganization or liquidation, the Board of Directors shall
authorize the issuance or assumption of a stock option or stock
options in a transaction to which Section 424(a) of the IRC
applies, then, notwithstanding any other provision of the Plan, the
Committee may grant an option or options upon such terms and
conditions as it may deem appropriate for the purpose of assumption
of the old option, in conformity with the provisions of such
Section 424(a) and the regulations thereunder, as they may be
amended from time to time; provided, however, that no such grant
may be made to a non-employee director.
     
     (e)  No adjustment or substitution provided for in this Section 13
shall require the Corporation to issue or to sell a fractional
share under any stock option or Stock Appreciation Rights agreement
and the total adjustment or substitution with respect to each stock
option or Stock Appreciation Rights agreement shall be limited
accordingly.

(f)  In the case of any adjustment or substitution provided for in
this Section 13, the price per share in each stock option and SAR
agreement shall be equitably adjusted by the Committee to reflect
the greater or lesser number of shares of stock or other securities
into which the stock covered by the option or SAR may have been
changed or which may have been substituted therefor.
     Section 14.  Amendment and Termination.  The Board of
Directors may modify, amend, or terminate the Plan at any time
except that, to the extent then required by applicable law, rule,
or regulation, approval of the holders of a majority of shares of
Common Stock represented in person or by proxy at a meeting of the
stockholders will be required to increase the maximum number of
shares of Common Stock available for distribution under the Plan
(other than increases due to adjustments in accordance with the
Plan and a one time increase that would not increase the amount of
Common Stock issuable under the Plan by more than 10%).
Notwithstanding the foregoing, an amendment revising the price,
date of exercisability, option period of or amount of shares under
a Stock Option granted to a non-employee director shall not be made
more frequently than once every six months unless necessary to
comply with the IRC or with the Employee Retirement Income Security
Act of 1974, as amended, or the Rules promulgated thereunder,
respectively.  No modification, amendment, or termination of the
Plan shall adversely affect the rights of a participant under a
grant previously made to him without the consent of such
participant.

     Section 15.  Compliance with Governmental Regulations.
Notwithstanding any provision of the Plan or the terms of any stock
option or SAR agreement issued under the Plan, the Corporation
shall not be required to issue any shares hereunder prior to the
registration of the shares subject to the Plan under the Securities
Act of 1933 or the Securities Exchange Act of 1934, if such
registration shall be necessary, or before compliance by the
Corporation or any participant with any other provisions of either
of those acts or of regulations or rulings of the Securities and
Exchange Commission thereunder, or before compliance with all other
applicable Federal and state laws and regulations and rulings
thereunder.  The Corporation shall use its best efforts to effect
such registrations and to comply with such laws, regulations and
rulings forthwith upon advice by its counsel that any such
registration or compliance is necessary.

     Section 16.  Compliance with Rule 16b-3.  It is the
Corporation's intent that the Plan comply in all respects with Rule
16b-3 of the Exchange Act and any regulations promulgated
thereunder.  If any provision of this Plan is later found not to be
in compliance with the Rule, the provisions shall be deemed null
and void.  All grants and exercises of options under this Plan by
individuals subject to Section 16 of the Exchange Act shall be
executed in accordance with the requirements of Section 16, as
amended, and any regulations promulgated thereunder.

     Section 17.  Tax Withholding.

     
     (a)  Whenever shares are to be issued under the Plan, the
Corporation shall have the right to require the grantee to remit to
the Corporation an amount sufficient to satisfy Federal, state and
local tax withholding requirements prior to the delivery of any
certificate for such shares.  If a grantee makes a disposition of
shares acquired upon the exercise of an Incentive Stock Option
within either two years after grant or one year after the receipt
of Common Stock by the grantee, the grantee shall promptly notify
the Corporation and the Corporation shall have the right to require
the grantee to pay to the Corporation an amount sufficient to
satisfy Federal, state and local tax withholding requirements.
Whenever payments are to be made in cash, such payments shall be
net of an amount sufficient to satisfy Federal, state and local tax
withholding requirements and authorized deductions.

     
     (b)  A grantee who is obligated to pay to the Corporation an amount
required to be withheld under applicable income tax laws in
connection with the exercise of Non-Statutory Stock Options under
the Plan may elect to satisfy this withholding obligation, in whole
or in part, by requesting that the Corporation withhold shares of
Common Stock otherwise issuable to the grantee upon exercise of the
option or by delivering to the Corporation already owned shares of
Common Stock of the Corporation having a Fair Market Value on the
date on which the amount of tax to be withheld is determined (the
"Tax Date") equal to the amount of the tax required to be withheld.
Any fractional amount shall be paid to the Corporation by the
grantee in cash or shall be withheld from the grantee's next
regular paycheck.

     
     (c)  An election by a grantee to have shares of Common Stock
withheld or to deliver to the Corporation already owned shares of
Common Stock of the Corporation to satisfy Federal, state and local
tax withholding requirements pursuant to subparagraph (b) above
(the "Election"), shall be subject to the following restrictions:

          
          i)   The Election must be in writing and delivered to the
               Corporation prior to the Tax Date;
               
          
          ii)  The Election shall be irrevocable by the grantee; and
               
          
          iii) The Election shall be subject to approval by the Committee,
               which approval may be granted or withdrawn at any time prior to
               the Tax Date.
               
     
     (d)  Notwithstanding the provisions of subparagraphs (a)-(c) above,
if a grantee is an officer or director of the Corporation, as
defined for purposes of Rule 16b-3 under the Exchange Act, as
amended, and withholding of any Federal, state or local taxes is
required, the Corporation shall hold back from the shares of Common
Stock to be delivered that number of shares having a Fair Market
Value equal to the amount of tax to be withheld to satisfy the tax
withholding obligation.

     Section 18.  Governing Law.  The Plan shall be construed and
its provisions enforced and administered in accordance with the
laws of the Commonwealth of Pennsylvania applicable to contracts
entered into and performed entirely in such state.

     Section 19.  Designation of Beneficiary.  An Employee
Participant may designate, in a writing delivered to the
Corporation before his or her death, a person or persons to
receive, in the event of the Employee Participant's death, any
rights to which he or she would be entitled under the Plan.  An
Employee Participant may also designate an alternate beneficiary to
receive payments if the primary beneficiary does not survive the
Employee Participant.  An Employee Participant may designate more
than one person as his or her beneficiary or alternate beneficiary,
in which case such persons would receive payments as joint tenants
with a right of survivorship.  A beneficiary designation may be
changed or revoked by an Employee Participant at any time by filing
a written statement of such change or revocation with the
Corporation.  If an Employee Participant fails to designate a
beneficiary, then his estate shall be deemed to be his beneficiary.

     Section 20.  Employment Rights.  Neither the Plan nor any
action taken hereunder shall be construed as giving any employee of
the Corporation the right to become a Employee Participant, and a
grant under the Plan shall not be construed as giving any Employee
Participant any right to be retained in the employ of the
Corporation.

     Section 21.  Expenses.  The expenses of administering the Plan
shall be borne by the Corporation.

     Section 22.  Indemnification.  Service on the Committee shall
constitute service as a member of the Board so that members of the
Committee shall be entitled to indemnification and reimbursement as
directors of the Corporation pursuant to its Articles of
Incorporation, By-Laws, or resolutions of the Board or
shareholders.

     Section 23.  Relationship to Other Benefits.  No payment under
the Plan shall be taken into account in determining any benefits
under any retirement, group insurance, or other employee benefit
plan of the Corporation.  The Plan shall not preclude the
shareholders of the Corporation, the Board or any committee
thereof, or the Corporation from authorizing or approving other
employee benefit plans or forms of incentive compensation, nor
shall it limit or prevent the continued operation of other
incentive compensation plans or other employee benefit plans of the
Corporation or the participation in any such plans by Employee
Participants in the Plan.

     Section 24.  No Trust or Fund Created.  Neither the Plan nor
any grant made hereunder shall create or be construed to create a
trust or separate fund of any kind or a fiduciary relationship
between the Corporation and an Employee Participant or any other
person.  To the extent that any person acquires a right to receive
payments from the Corporation pursuant to a grant under the Plan,
such right shall be no greater than the right of any unsecured
general creditor of the Corporation.

     Section 25.  Effective Date of the Plan.  The Plan shall
become effective immediately upon approval of the Plan by the Board
provided that the Plan shall thereafter be approved by a majority
of the outstanding shares of the Corporation at the Annual Meeting
of the Shareholders of the Corporation on April 28, 1994.  No
options shall be granted hereunder until the Committee shall have
been advised by the Corporation's counsel that all applicable legal
requirements have been satisfied and that appropriate rulings, if
any, which are required from governmental agencies, have been
obtained.



As amended effective December 12, 1995.


                           (Page )
                              
                              
                              
                          AGREEMENT

     This Agreement made as of this 1st day of June , 1993 by
and between Dravo Corporation, a Pennsylvania corporation
(the "Corporation") and James J. Puhala an individual
residing in the State of Alabama and an employee of the
Corporation (the "Executive").

                         WITNESSETH:

     WHEREAS, the Board of Directors of the Corporation has
determined that it is in the best interests of the
Corporation to enter into this Agreement with the Executive;
and

     WHEREAS, the Executive desires to obtain certain
benefits in the event his employment is terminated due to a
Change-in-Control of the Corporation;

     NOW, THEREFORE, the parties hereto, each intending to be
legally bound hereby, agree as follows:

1.      Definition of Terms.  The following terms when used
   in this Agreement shall have the meaning hereafter set
   forth:

    (a)      "Annual Salary Adjustment Percentage" shall mean
        the mean average percentage increase in base salary
        for all elected officers of the Corporation during
        the two full calendar years immediately preceding the
        time to which such percentage is being applied;
        provided, however, that if after a Change-in-Control,
        as hereinafter defined, there should be a significant
        change in the number of elected officers of the
        Corporation or in the manner in which they are
        compensated, then the foregoing definition shall be
        changed by substituting for the phrase "elected
        officers of the Corporation" the phrase "persons then
        performing the functions formerly performed by the
        elected officers of the Corporation."
   
    (b)      "Cause for Termination" shall mean
   
        (i)     the deliberate and intentional failure by
            the Executive to devote substantially his entire
            business time and best efforts to the performance
            of his duties (other than any such failure
            resulting from the Executive's incapacity due to
            physical or mental illness or disability) after a
            demand for substantial performance is delivered
            to the Executive by the Board of Directors of the
            Corporation which specifically identifies the
            manner in which the Board believes that the
            Executive has not substantially performed his
            duties,
        or
        
        (ii)    the deliberate and intentional engaging by
            the Executive in gross misconduct materially and
            demonstrably injurious to the Corporation.
        
        For purposes of this definition, no act, or failure
        to act, on the Executive's part shall be considered
        "deliberate and intentional" unless done, or omitted
        to be done, by the Executive not in good faith and
        without reasonable belief that his action or omission
        was in the best interests of the Corporation.

   (c)  "Change-in-Control" shall mean a change in control of
        the Corporation of such a nature that it would be
        required to be reported by the Corporation in
        response to item 6(e) of Schedule 14A of Regulation
        14A promulgated under the Securities Exchange Act of
        1934, as in effect on the date hereof ("Exchange
        Act"); provided, however, that without respect to the
        foregoing, such a change in control shall be deemed
        to have occurred if
   
        (i)     any "person" (as such term is used in
            Sections 13(d) and 14(d)(2) of the Exchange Act)
            is or becomes the beneficial owner, directly or
            indirectly, of securities of the Corporation
            representing 20% or more of the combined voting
            power of the Corporation's then outstanding
            securities;
        
         or
        
        (ii)    during any period of three consecutive
            years, individuals who at the beginning of such
            period constitute the Board of Directors of the
            Corporation (the "Board") cease for any reason to
            constitute at least a Majority thereof unless the
            election, or the nomination for election by the
            Corporation's shareholders, of each new director
            was approved by a vote of at least two-thirds of
            the directors then still in office who were
            directors at the beginning of the period.

    (d)      "Date of Termination" shall mean
   
              (i)  if the Executive's employment is
               terminated for Disability, thirty (30) days
               after a Notice of Termination is given to the
               Executive (provided that the Executive shall
               not have returned to the performance of the
               Executive's duties on a full time basis during
               such thirty (30) day period);
        
              (ii)      if the Executive's employment
               terminates due to his death or Retirement, the
               date of death or Retirement, respectively;
        
              (iii)     if the Executive terminates
               employment upon Good Reason for Termination,
               the date specified for termination in any
               notice delivered to the Corporation by the
               Executive; or
        
              (iv) if the Executive's employment is
               terminated for any other reason, the date on
               which a termination becomes effective pursuant
               to a Notice of Termination; provided, however,
               that if within thirty (30) days after any
               Notice of Termination is given the party
               receiving such Notice of Termination notifies
               the other party that a dispute exists
               concerning the termination, the Date of
               Termination shall be the date on which the
               dispute is finally determined, either by
               mutual written agreement of the parties, by a
               binding and final arbitration award or by a
               final judgment, order or decree of a court of
               competent jurisdiction (the time for appeal
               therefrom having expired and no appeal having
               been perfected).
   
   (e)  "Disability" shall mean such incapacity due to
        physical or mental illness or injury as causes the

    (f)      "Good Reason for Termination" shall mean:
   
              (i)  without the Executive's express written
               consent, the assignment to the Executive of
               any duties inconsistent with his positions,
               duties, responsibilities and status with the
               Corporation immediately prior to a Change-in-
               Control, or a change in his reporting
               responsibilities, titles or offices as in
               effect immediately prior to a Change-in-
               Control, or any removal of the executive from
               or any failure to re-elect the Executive to
               any of such positions, except in connection
               with the termination of the Executive's

              (ii)      a reduction by the Corporation in
               the Executive's base salary as in effect
               immediately prior to the Change-in-Control or
               as the same may be increased from time to time
               or the failure by the Corporation to increase
               such base salary each year after the year in
               which the Change-in-Control occurs by an
               amount which at least equals, on a percentage
               basis, the Annual Salary Adjustment
               Percentage;
              (iii)     a failure by the Corporation to
               continue to provide incentive compensation
               comparable to that provided by the
               Corporation's Incentive Compensation Plan as
               the same may from time to time prior to a
               Change-in-Control be modified or superseded by
               another plan (the "Incentive Compensation
               Plan"), or a failure by the Corporation to
               continue the Executive as a participant in the

              (iv)      the Corporation's requiring the
               Executive to be based anywhere other than the
               Corporation's executive offices at which the
               Executive has his principal office immediately
               prior to the Change-in-Control, except for
               required travel on the Corporation's business
               to an extent substantially consistent with the
               Executive's present business travel
               obligations immediately prior to the Change-in-
               Control, or, in the event the Executive
               consents to any such relocation of the
               Corporation's principal executive offices, the
               failure by the Corporation to pay (or
               reimburse the Executive for) all reasonable

               principal residence in connection with such
               relocation and to indemnify the Executive
               against any loss (defined as the difference
               between the actual sale price of such
               residence and the higher of (a) the
               Executive's aggregate investment in such
               residence or (b) the fair market value of such
               residence as determined by a real estate
               appraiser designated by the Executive and
               reasonably satisfactory to the Corporation)
               realized in the sale of the Executive's
               principal residence in connection with any
               such change of residence;
        
              (v)  the failure by the Corporation to
               continue in effect any benefit or compensation
               plan (including but not limited to the
               Corporation's Long-Term Incentive Award Plan
               of 1983, Stock Option Plan of 1978, Employee
               Stock Option Plan of 1988, Stock Option Plan

               Executive is participating immediately prior
               to the Change-in-Control (provided, however,
               that there shall not be deemed to be any such
               failure if the Corporation substitutes for the
               discontinued plan, a plan providing the
               Executive with substantially similar
               benefits), the taking of any action by the
               Corporation which would adversely affect the
               Executive's participation in or materially
               reduce the Executive's benefits under any of
               such plans or deprive the Executive of any
               material fringe benefit enjoyed by the
               Executive immediately prior to the Change-in-
               Control, or the failure by the Corporation to
               provide the Executive with the number of paid
               vacation days to which the Executive is then
               entitled on the basis of years of service with
               the Corporation in accordance with the
               Corporation's normal vacation policy all as
               and to the extent they are in effect
               immediately prior to the Change-in-Control;
        
              (vi)      the failure of the Corporation to
               obtain the assumption of this Agreement by any
               successor as contemplated in Section 9(c)
               hereof; or
        
              (vii)     any purported termination of the
               employment of the Executive by the Corporation
               which is not (A) due to the Executive's
               Disability, death, Retirement (as hereinafter
               defined) or in accordance with section 2
               hereof, or (B) effected pursuant to a Notice
               of Termination satisfying the requirements of
               subsection (g) below;
        
              (viii)    notwithstanding the foregoing, it
               shall not be deemed Good Reason for
               Termination if the Corporation, acting in good
               faith, makes changes to any compensation or
               benefits plan or program that is made
               available on a nondiscriminatory basis to the
               salaried employees of the Corporation, which
               changes do not apply disproportionately to the
               elected officers of the Corporation or those
               persons then performing the functions formerly
               performed by the elected officers of the
               Corporation.
        
   (g)  "Notice of Termination" shall mean a written
        statement which sets forth the specific reason for
        termination and, if such is claimed to be Cause for
        Termination, in reasonable detail the facts and
        circumstances which indicate that such is Cause for
        Termination together with notice of the time and
        place of the meeting of the Board of Directors of the
        Corporation called to consider such matter in
        accordance with section 2 hereof.

    (h)      "Options" shall mean any stock options issued
        pursuant to the Corporation's Employee Stock Option
        Plan of 1988, Long-Term Incentive Award Plan of 1983,
        Stock Option Plan of 1978 or any future stock option
        plan.
    (i)      "Retirement" shall mean a termination of the
        Executive's employment after age 65 or in accordance
        with any mandatory retirement arrangement with
        respect to an earlier age agreed to by the Executive.
   
   (j)  "Stock Appreciation Rights" shall mean any stock
        appreciation rights issued pursuant to the
        Corporation's Employee Stock Option Plan of 1988,
        Long-Term Incentive Award Plan of 1983, Stock Option
        Plan of 1978 or any future stock appreciation rights
        plan.

2.      "Termination by the Corporation Due to Cause for
   Termination."
   If the Corporation desires to terminate the Executive's
   employment due to Cause for Termination, the Corporation
   shall first deliver a Notice of Termination to the
   Executive.  Thereafter, the Board of Directors at a
   meeting held not less than two weeks nor more than four
   weeks after the delivery of the Notice Of Termination
   shall consider whether cause for Termination exists.
   Cause for Termination shall not be deemed to exist under
   this Agreement unless and until the Board determines in
   good faith by the affirmative vote of not less than three-
   quarters of the entire membership of the Board that the
   Executive has engaged in conduct which is Cause for
   Termination.  Should the Board determine that Cause for
   Termination exists, the Board may at that time or during a
   period of two weeks thereafter terminate the Executive's
   employment due to Cause for Termination by adopting at
   such time or during such period by a similar three-
   quarters vote a resolution terminating the Executive's
   employment. If the Board fails to adopt within such two-
   week period a resolution terminating the Executive's
   employment, then the Corporation shall be deemed to have
   waived its right to terminate the Executive due to those
   circumstances which constituted the Cause for Termination
   previously found to exist by the Board.

 3.     Termination Payments Following Change-in-Control.

    (a)      If, during the term of this Agreement, a Change-
        in-Control shall have occurred and the Executive's
        employment with the Corporation shall be terminated

              (i)  due to the Executive's death,
        
              (ii)      by the Executive unless terminated
               for Good Reason for Termination, or
        
              (iii)     by the Corporation in accordance
               with section 2 hereof or for Disability or
               Retirement, then the Corporation shall have no
               obligations hereunder to the Executive and the
               only obligations of the  Corporation to the
               Executive shall be in accordance with any
               other employment agreement applicable to the
               Executive and the then various policies,
               practices and benefit plans of the
               Corporation.
   
   (b)  If during the term of this Agreement both a Change-in-
        Control shall have occurred and the Executive's
        employment with the Corporation shall have terminated
        other than under the circumstances above described in
        Subsection 3(a), then the Corporation shall pay or
        cause to be paid on or before the fifth day following
        the Date of Termination in cash to the Executive the
        following sums:
        
              (i)  any unpaid portion of the Executive's
               full base salary for the period from the last
               period for which the Executive was paid to the
               Date of Termination;
        
              (ii)      any then deferred portions of cash
               awards (including deferred awards which but
               for this provision would not be payable until
               subsequent to the Date of Termination) made to
               the Executive under the Executive incentive
               Compensation Plan; and
        
              (iii)     an amount as liquidated damages for
               lost future remuneration equal to the product
               obtained by multiplying

               (A)  the lesser of
                  
                    (1)     three or
                    
                    (2)     a number equal to the number of
                       calendar months remaining from the
                       Date of Termination to the date on
                       which the Executive is 65 years of age
                       (or, if earlier, the age agreed to by
                       the Executive pursuant to any prior
                       arrangement) divided by twelve
                    
                     times
             
                (B)      the sum of

                    (1)     the greater of
                  
                       (i)     the Executive's base salary
                           for the year in effect on the Date
                           of Termination (provided that in
                           the case of Termination for Good
                           Reason by the Executive the date
                           immediately preceding the date of
                           the earliest event which gave rise
                           to the Termination for Good Reason
                           by the Executive shall be used
                           instead of the Date of
                           Termination)
                       
                          or
                       
                       (ii)    the Executive's base salary
                           for the year in effect on the date
                           of the Change-in-Control;
                       
                       provided that "base salary for the
                       year" shall be the amount of base
                       salary for the year established by the
                       Board of Directors at the beginning of
                       the fiscal year in question in
                       accordance with the compensation
                       policies and practices of the
                       Corporation, without regard to any
                       reduction in the amount actually paid
                       to the Executive during such year as a
                       result of any plan of the Corporation
                       to reduce compensation due to economic
                       considerations, and without regard to
                       any deferral of compensation payable
                       to the Executive for services rendered
                       during such year to a subsequent year.

                     plus
                    
                    (2)     the greater of

                           received by the Executive under
                           the Executive Incentive
                           Compensation Plan for the two
                           calendar years immediately
                           preceding the Date of Termination
                           (provided that in the case of
                           Termination for Good Reason by the
                           Executive the date immediately
                           preceding the date of the event
                           which gave rise to the Termination
                           for Good Reason by the Executive
                           shall be used instead of the Date
                           of Termination;

                           for the two calendar years
                           immediately preceding the date of
                           the Change-in-Control.

   (c)  Notwithstanding any other provisions of this
        Agreement, in the event that any payment or benefit
        received or to be received by the Executive pursuant
        to the terms of this Agreement or otherwise
        (collectively the "Total Payments") would not be
        deductible, in whole or part, as a result of section
        280G of the Internal Revenue Code of 1986, as amended
        (the "Code") by the Corporation, an affiliate or
        other person making such payment or providing such
        benefit, the payments due under this Agreement (the
        "Contract Payments") shall be reduced until no
        portion of the Total Payments is not deductible, or
        the Contract Payments are reduced to zero.  For
        purposes of this limitation (i) no portion of the
        Total Payments the receipt or enjoyment of which you
        shall have effectively waived in writing prior to the
        date of payment of the Contract Payments shall be
        taken into account, (ii) no portion of the Total
        Payments shall be taken into account which in the
        opinion of tax counsel selected by the Corporation's
        independent auditors and acceptable to you does not
        constitute a "parachute payment" within the meaning
        of section 280G(b)(2) of the Code, (iii) the Contract
        Payments shall be reduced only to the extent
        necessary so that the Total Payments (other than
        those referred to in clauses (i) or (ii) in their
        entirety constitute reasonable compensation for
        services actually rendered within the meaning of
        section 280G(b)(4) of the Code or are otherwise not
        subject to disallowance as deductions, in the opinion
        of the tax counsel referred to in clause (ii); and
        (iv) the value of any non-cash benefit or any
        deferred payment or benefit included in the Total
        Payments shall be determined by the Corporation's
        independent auditors in accordance with the
        principles of sections 280G(d)(3) and (4) of the
        Code.
   
4.      Stock Appreciation Rights and Stock Options.

   (a)     If the Executive's employment should terminate
       under such circumstances as entitle the Executive to
       receive payments pursuant to section 3(b) hereof,
       then, in lieu of Stock Appreciation Rights granted to
       the Executive (and whether or not they are in tandem
       with any Options, but provided that this subsection
       shall not apply to any Stock Appreciation Rights in
       tandem with incentive stock options) that were
       outstanding for at least six months prior to the Date
       of Termination and that were neither subsequently
       exercised nor expired by their terms prior to the Date
       of Termination (which rights and any related in tandem
       options shall be cancelled upon the making of the
       payment hereafter described), the Executive shall
       receive an amount in cash on or before the fifth day
       following the Date of Termination equal to the
       difference, if positive, obtained by
   
              (i)  taking the product obtained by
               multiplying
            
               (A)  the number of such stock appreciation
                    rights
               
                times
                
               (B)  the greater of
                     
                    (1)     the mean between the highest and
                       lowest quoted selling prices for the
                       Corporation's common stock on the
                       composite tape for the New York Stock
                       Exchange on the trading day
                       immediately preceding the Date of
                       Termination;
                    
                       or
                    
                    (2)     the highest price paid per share
                       for the Corporation's common stock in
                       the transaction resulting in the
                       actual Change-in-Control.
                    
          and
       
              (ii)      subtracting therefrom the aggregate
               of the products obtained by multiplying the
               mean between the highest and lowest quoted
               selling prices for the Corporation's Common
               Stock on the composite tape for the New York
               Stock Exchange on each date of grant of such
               Stock Appreciation Rights times the number of
               such Stock Appreciation Rights granted on such
               date.
       
   (b)     If the Executive's employment should terminate
       under such circumstances as entitle the Executive to
       payments pursuant to Section 3(b) hereof then the
       Executive may elect, during the 60-day period from and
       after a Change of Control (other than a Change of
       Control initiated by the Executive), to surrender his
       rights in any of the options granted to the Executive
       provided that this subsection shall not apply to any
       Options accompanied by a Stock Appreciation Right that
       were outstanding for at least six months prior to the
       Date of Termination and that were neither subsequently
       exercised nor expired by their terms prior to the Date
       of Termination and, upon such surrender, the
       Corporation shall pay to the Executive an amount of
       cash with respect to each such option equal to the
       difference, if positive, obtained by
       
              (i)  taking the product obtained by
               multiplying
           
               (A)  the number of shares of common stock as
                    to which the option is exercisable
               
                    times
               
                (B)      the greater of
               
                    (1)     the mean between the highest and
                       lowest quoted selling prices for the
                       Corporation's Common Stock on the
                       composite tape for the New York Stock
                       Exchange on the trading day
                       immediately preceding the Date of
                       Termination
                    
                       or
                    
                    (2)     the highest price paid per share
                       for Corporation's Common Stock in the
                       transaction resulting in the actual
                       Change-in-Control
                    
                    and
       
              (ii)      subtracting therefrom the option
               price for such Shares of Common Stock.
   
   (c)     In the event the Executive's employment should
       terminate under such circumstances as entitle the
       Executive to payments pursuant to Section 3(b) hereof,
       the Corporation agrees to accelerate and make
       immediately exercisable in full all unmatured options
       held by the Executive at the Date of Termination,
       whether or not otherwise exercisable, effective as of
       the Date of Termination.  In the event that the
       Executive has been granted Incentive Stock Options
       pursuant to Section 422A(b)(7) of the Internal Revenue
       Code of 1986 (the "Code") which would otherwise become
       immediately exercisable hereunder but for the
       limitation imposed by Code Section 422A(b)(7), such
       options shall only become exercisable as to the
       maximum number of shares permitted by Code Section
       422A(b)(7) and the balance of such options shall
       become exercisable at the earliest date or dates
       thereafter permitted by Code Section 422A(b)(7), with
       those options with the lowest exercise prices becoming
       exercisable at the earliest date or dates.
 5.     Retirement Benefits.

    (a)      If the Executive's employment should terminate
        under such circumstances as entitle the Executive to
        receive payments pursuant to section 3(b) hereof,
        then, notwithstanding such termination, the Executive
        shall be deemed to continue as an active employee
        participant in the Corporation's pension plan for
        salaried employees, and the benefits payable to him,
        his surviving spouse or contingent annuitant shall be
        calculated as if he had been continuously employed by
        the Corporation for those years (including parts
        thereof) subsequent to the Date of Termination and
        prior to the earlier of (i) three years subsequent to
        the Date of Termination, and (ii) the Executive's
        death or attainment of age 65 (or, if earlier, the
        age agreed to by the Executive pursuant to any prior
        arrangement), at the covered remuneration set forth
        in the following sentences of this subsection.  The
        covered remuneration for any part of a year remaining
        after the Date of Termination shall equal the number
        of months remaining in such year times the sum
        determined pursuant to section 3(b)(iv)(B) hereof and
        divided by twelve. The covered remuneration for the
        first full credited year following the Date of
        Termination shall equal the sum determined pursuant
        to section 3(b)(iv)(B) hereof.  The covered
        remuneration for the first full credited year after
        the first full credited year shall equal the sum of
        (i) the covered remuneration for the immediately
        preceding year plus (ii) the product of the Annual
        Salary Adjustment percentage for such credited years
        times the covered remuneration for the immediately
        preceding year.
   
   (b)  If for any reason whether by law or the terms of the
        Corporation's pension plan, such pension plan cannot
        either use the above credited years of service and
        remuneration above described in subsection 5(a) for
        purposes of the Executive's pension benefits
        (including surviving spouse and contingent annuitant
        benefits) or cannot pay the full amount of benefits
        which would result from the foregoing subsections,
        then the Corporation hereby contractually agrees to
        pay the difference between
        
              (i)  the benefits which would be payable if
               the pension plan had been able to pay such
               benefits based upon the credited years of
               service and covered remuneration above
               described in subsection 5(a),
        
         and
        
              (ii)      the benefits, if any, actually paid
               to the Executive, his surviving spouse or
               contingent annuitant by the pension plan.
        
        The Corporation shall not be required to fund its
        obligation to pay the foregoing difference.

 6. Other Benefit Plans.

    (a)      If the Executive's employment should terminate
        under such circumstances as entitle the Executive to
        receive payments pursuant to section 3(b) hereof and
        if the Executive is a participant in the
        Corporation's Executive Benefit Plan (or a plan
        providing comparable benefits) shall be in effect
        prior to the Change-in-Control, then the Executive
        will be deemed for purposes of such Plan (or, if
        applicable, the plan providing comparable benefits)
        to have continuously remained in the employ of the
        Corporation until the earlier of (i) three years
        subsequent to the Date of Termination, and (ii) his
        death or attainment of age 65 (or the age agreed to
        by the Executive pursuant to any prior arrangement),
        at a total compensation equal to his total
        compensation in effect on the Date of Termination
        (provided that in the case of Termination for Good
        Reason by the Executive the date immediately
        preceding the date of the earliest event which gave
        rise to the Termination for Good Reason by the
        Executive shall be used instead of the Date of
        Termination) and to have made any required
        contributions due thereunder.  The Executive will be
        eligible to receive all benefits under such Plan (or,
        if applicable, the plan providing comparable
        benefits) payable as though he had so remained in the
        Corporation's employ and had made any required
        contributions notwithstanding that he neither was so
        employed nor made any such contributions.
   
   (b)  Except with respect to (i) any Stock Appreciation
        Rights and Stock Options, as to which payment is
        provided in Section 4(a) hereof, (ii) the
        Corporation's pension plan, which is governed by
        paragraph 5 hereof, (iii) the Executive Benefit Plan,
        and (iv) the Incentive Compensation Plan, the
        Executive shall be deemed for purposes of all
        employee benefits to have remained in the continuous
        employment of the Corporation for a period of three
        years following the Date of Termination and shall be
        entitled to all of the benefits provided by such
        plans as though he had so remained in the employment
        of the Corporation.
   
   (c)  If for any reason, whether by law or provisions of
        the Corporation's employee benefit plans, any
        benefits which the Executive would be entitled to
        under the foregoing subsections of this section 6
        cannot be paid pursuant to such employee benefit
        plans, then the Corporation hereby contractually
        agrees to pay to the Executive the difference between
        the benefits which the Executive would have received
        in accordance with the foregoing subsections of this
        section if the relevant employee benefit plan could
        have paid such benefit and the amount of benefits, if
        any, actually paid by such employee benefit plan.
        The Corporation shall not be required to fund its
        obligation to pay the foregoing difference.

 7.Other Employment.

    (a) The Executive shall have no duty to seek any other
        employment after termination of his employment with
        the Corporation and the Corporation hereby waives and
        agrees not to raise or use any defense based on the
        position that the Executive had a duty to mitigate or
        reduce the amounts due him hereunder by seeking other
        employment whether suitable or unsuitable.

   (b)  Should the Executive obtain other employment, then
        the only effect of such on the obligations of the
        Corporation hereunder shall be that the Corporation
        shall be entitled to credit against any payments
        which would otherwise be made pursuant to sections 5,
        6(a) or 6(b) hereof, any comparable payments to which
        the Executive is entitled under the pension or other
        employee benefit plans maintained by the Executive's
        other employers after termination of his employment
        with the Corporation.  In no event shall any sums
        received by the Executive from any other employment
        be credited against or otherwise reduce the amounts
        payable by the Corporation pursuant to Sections 3 or
        4 hereof.

 8.Term.

    (a)      This Agreement shall be for a term expiring
        August 31, 1998 and shall automatically be extended
        for successive five year terms at the end of each
        preceding term unless termination occurs pursuant to
        subsection (b) or (c) below, whichever is applicable.

    (b)      If a Change-in-Control has occurred, this
        Agreement shall remain in effect until terminated on
        the date which is three years from the Change-in-
        Control.

    (c)      If a Change-in-Control has not occurred, this
        Agreement shall terminate if the Executive's
        employment with the Corporation terminates for any
        reason whether such termination of employment is by
        the Corporation or by the Executive.  Otherwise,
        prior to a Change-in-Control, this Agreement may only
        be terminated by the Corporation upon the giving by
        the Corporation of notice of termination at least
        thirty days prior to the end of the then term, in
        which event this Agreement shall terminate at the end
        of such term.

 9. Miscellaneous.

    (a)      This Agreement shall be construed under the laws
        of the Commonwealth of Pennsylvania.
   
    (b)      This Agreement constitutes the entire
        understanding of the parties hereto with respect to
        the subject matter hereof and may only be amended or
        modified by written agreement signed by the parties
        hereto.
   
    (c)      The Corporation will require any successor
        (whether direct or indirect, by purchase, merger,
        consolidation or otherwise) to all or substantially
        all of the business and/or assets of the Corporation,
        by agreement in form and substance satisfactory to
        the executive, to  expressly assume and agree to
        perform this Agreement in the same manner required of
        the Corporation and to perform it as if no such
        succession had taken place.  Failure of the
        Corporation to obtain such agreement prior to the
        effectiveness of any such succession shall be a
        breach of this Agreement and shall entitle the
        Executive to terminate employment due to Good Reason
        for Termination. As used in this Agreement,
        "Corporation" shall mean the Corporation as
        hereinbefore defined and any successor to its
        business and/or assets as aforesaid which executes
        and delivers the agreement provided for in this
        subsection (c) or which otherwise becomes bound by
        all the terms and provisions of this Agreement by
        operation of law.
   
   (d)  This Agreement shall inure to the benefit of and be
        enforceable by the Executive or his legal
        representatives, executors, administrators,
        successors, heirs, distributees, devisees and
        legatees.  If the Executive should die while any
        amounts would still be payable to him hereunder if he
        had continued to live, all such amounts, unless
        otherwise provided herein, shall be paid in
        accordance with the terms of this Agreement to his
        devisee, legatee or other designee or if there be no
        such designee, to his estate.
   
   (e)  Any notice or other communication provided for in
        this Agreement shall be in writing and, unless
        otherwise expressly stated herein, shall be deemed to
        have been duly given if mailed by United States
        registered mail, return receipt requested, postage
        prepaid addressed
        in the case of the Executive to his office at the
        Corporation with a copy to his residence and in the
        case of the Corporation to its principal executive
        offices, attention of the Chief Executive Officer.
   
   (f)  No provisions of this Agreement may be modified,
        waived or discharged unless such waiver, modification
        or discharge is agreed to in writing signed by the
        Executive and approved by resolution of the Board of
        Directors of the Corporation.  No waiver by either
        party hereto at any time of any breach by the other
        party hereto of, or compliance with, any condition or
        provision of this Agreement to be performed by such
        other party shall be deemed a waiver of similar or
        dissimilar provisions or conditions at the same or at
        any prior or subsequent time.  Except for any
        employment agreement with the Executive, no
        agreements or representations, oral or otherwise,
        express or implied, with respect to the subject
        matter hereof have been made by either party which
        are not set forth expressly in  this Agreement.  To
        the extent that the provisions of this Agreement are
        in conflict with any such employment agreement,
        following a Change-in-Control the employment
        agreement shall automatically be amended in
        accordance with this Agreement and the provisions of
        this Agreement shall govern.
   
   (g)  The invalidity or unenforceability of any provisions
        of this Agreement shall not affect the validity or
        enforceability of any other provision of this
        Agreement, which shall remain in full force and
        effect.

   (h)  This Agreement may be executed in one or more
        counterparts, each of which shall be deemed to be an
        original but all of which together will constitute
        one and the same instrument.

     IN WITNESS WHEREOF, this Agreement has been executed on
the date first above written.

ATTEST:                        DRAVO CORPORATION


/s/ A. H. TENHUNDFELD, JR.                   By /s/ JOHN R. MAJOR
                                             /s/  JAMES J. PUHALA
                               


                           (Page )
                          AGREEMENT

     This Agreement made as of this 1st day of January , 1995
by and between Dravo Corporation, a Pennsylvania corporation
(the "Corporation") and Donald H. Stowe, Jr., an individual
residing in the State of Pennsylvania and an employee of the
Corporation (the "Executive").

                         WITNESSETH:

     WHEREAS, the Board of Directors of the Corporation has
determined that it is in the best interests of the
Corporation to enter into this Agreement with the Executive;
and

     WHEREAS, the Executive desires to obtain certain
benefits in the event his employment is terminated due to a
Change-in-Control of the Corporation;

     NOW, THEREFORE, the parties hereto, each intending to be
legally bound hereby, agree as follows:

1.      Definition of Terms.  The following terms when used
   in this Agreement shall have the meaning hereafter set
   forth:

    (a)      "Annual Salary Adjustment Percentage" shall mean
        the mean average percentage increase in base salary
        for all elected officers of the Corporation during
        the two full calendar years immediately preceding the
        time to which such percentage is being applied;
        provided, however, that if after a Change-in-Control,
        as hereinafter defined, there should be a significant
        change in the number of elected officers of the
        Corporation or in the manner in which they are
        compensated, then the foregoing definition shall be
        changed by substituting for the phrase "elected
        officers of the Corporation" the phrase "persons then
        performing the functions formerly performed by the
        elected officers of the Corporation."
   
    (b)      "Cause for Termination" shall mean
   
        (i)     the deliberate and intentional failure by
            the Executive to devote substantially his entire
            business time and best efforts to the performance
            of his duties (other than any such failure
            resulting from the Executive's incapacity due to
            physical or mental illness or disability) after a
            demand for substantial performance is delivered
            to the Executive by the Board of Directors of the
            Corporation which specifically identifies the
            manner in which the Board believes that the
            Executive has not substantially performed his
            duties,
        or
        
        (ii)    the deliberate and intentional engaging by
            the Executive in gross misconduct materially and
            demonstrably injurious to the Corporation.
        
        For purposes of this definition, no act, or failure
        to act, on the Executive's part shall be considered
        "deliberate and intentional" unless done, or omitted
        to be done, by the Executive not in good faith and
        without reasonable belief that his action or omission
        was in the best interests of the Corporation.

   (c)  "Change-in-Control" shall mean a change in control of
        the Corporation of such a nature that it would be
        required to be reported by the Corporation in
        response to item 6(e) of Schedule 14A of Regulation
        14A promulgated under the Securities Exchange Act of
        1934, as in effect on the date hereof ("Exchange
        Act"); provided, however, that without respect to the
        foregoing, such a change in control shall be deemed
        to have occurred if
   
        (i)     any "person" (as such term is used in
            Sections 13(d) and 14(d)(2) of the Exchange Act)
            is or becomes the beneficial owner, directly or

            Corporation's shareholders, of each new director
            was approved by a vote of at least two-thirds of
            the directors then still in office who were
            directors at the beginning of the period.

    (d)      "Date of Termination" shall mean
   
              (i)  if the Executive's employment is
               terminated for Disability, thirty (30) days
               after a Notice of Termination is given to the
               Executive (provided that the Executive shall
               not have returned to the performance of the
               Executive's duties on a full time basis during
               such thirty (30) day period);
        
              (ii)      if the Executive's employment

              (iv) if the Executive's employment is
               terminated for any other reason, the date on
               which a termination becomes effective pursuant
               to a Notice of Termination; provided, however,
               that if within thirty (30) days after any
               Notice of Termination is given the party
               receiving such Notice of Termination notifies

               final judgment, order or decree of a court of
               competent jurisdiction (the time for appeal
               therefrom having expired and no appeal having
               been perfected).
   
   (e)  "Disability" shall mean such incapacity due to
        physical or mental illness or injury as causes the

    (f)      "Good Reason for Termination" shall mean:
   
              (i)  without the Executive's express written
               consent, the assignment to the Executive of
               any duties inconsistent with his positions,
               duties, responsibilities and status with the
               Corporation immediately prior to a Change-in-
               Control, or a change in his reporting
               responsibilities, titles or offices as in

               with the termination of the Executive's
               employment due to a Cause for Termination,
               Disability or Retirement (as hereinafter
               defined) or as a result of the Executive's

               as the same may be increased from time to time
               or the failure by the Corporation to increase
               such base salary each year after the year in
               which the Change-in-Control occurs by an
               amount which at least equals, on a percentage
               basis, the Annual Salary Adjustment
               Percentage;
              (iii)     a failure by the Corporation to
               continue to provide incentive compensation
               comparable to that provided by the
               Corporation's Incentive Compensation Plan as
               the same may from time to time prior to a
               Change-in-Control be modified or superseded by
               another plan (the "Incentive Compensation
               Plan"), or a failure by the Corporation to
               continue the Executive as a participant in the
               Incentive Compensation Plan on at least the
               basis and according to the standards in effect

               Incentive Compensation Plan;
        
              (iv)      the Corporation's requiring the
               Executive to be based anywhere other than the
               Corporation's executive offices at which the
               Executive has his principal office immediately
               prior to the Change-in-Control, except for
               required travel on the Corporation's business
               to an extent substantially consistent with the
               Executive's present business travel
               obligations immediately prior to the Change-in-
               Control, or, in the event the Executive
               consents to any such relocation of the
               Corporation's principal executive offices, the
               failure by the Corporation to pay (or
               reimburse the Executive for) all reasonable
               moving expenses incurred by the Executive
               relating to a change of the Executive's
               principal residence in connection with such
               relocation and to indemnify the Executive
               against any loss (defined as the difference
               between the actual sale price of such
               residence and the higher of (a) the
               Executive's aggregate investment in such
               residence or (b) the fair market value of such
               residence as determined by a real estate
               appraiser designated by the Executive and
               reasonably satisfactory to the Corporation)
               realized in the sale of the Executive's
               principal residence in connection with any
               such change of residence;
        
              (v)  the failure by the Corporation to
               continue in effect any benefit or compensation
               plan (including but not limited to the
               Corporation's Long-Term Incentive Award Plan
               of 1983, Stock Option Plan of 1978, Employee
               Stock Option Plan of 1988, Stock Option Plan

               Executive is participating immediately prior
               to the Change-in-Control (provided, however,
               that there shall not be deemed to be any such
               failure if the Corporation substitutes for the
               discontinued plan, a plan providing the
               Executive with substantially similar
               benefits), the taking of any action by the
               Corporation which would adversely affect the
               Executive's participation in or materially
               reduce the Executive's benefits under any of
               such plans or deprive the Executive of any
               material fringe benefit enjoyed by the
               Executive immediately prior to the Change-in-
               Control, or the failure by the Corporation to
               provide the Executive with the number of paid
               vacation days to which the Executive is then
               entitled on the basis of years of service with
               the Corporation in accordance with the
               Corporation's normal vacation policy all as
               and to the extent they are in effect
               immediately prior to the Change-in-Control;
        
              (vi)      the failure of the Corporation to
               obtain the assumption of this Agreement by any
               successor as contemplated in Section 9(c)
               hereof; or
        
              (vii)     any purported termination of the
               employment of the Executive by the Corporation
               which is not (A) due to the Executive's
               Disability, death, Retirement (as hereinafter
               defined) or in accordance with section 2
               hereof, or (B) effected pursuant to a Notice
               of Termination satisfying the requirements of
               subsection (g) below;
        
              (viii)    notwithstanding the foregoing, it
               shall not be deemed Good Reason for
               Termination if the Corporation, acting in good
               faith, makes changes to any compensation or
               benefits plan or program that is made
               available on a nondiscriminatory basis to the
               salaried employees of the Corporation, which
               changes do not apply disproportionately to the
               elected officers of the Corporation or those
               persons then performing the functions formerly
               performed by the elected officers of the
               Corporation.
        
   (g)  "Notice of Termination" shall mean a written
        statement which sets forth the specific reason for
        termination and, if such is claimed to be Cause for
        Termination, in reasonable detail the facts and
        circumstances which indicate that such is Cause for
        Termination together with notice of the time and
        place of the meeting of the Board of Directors of the
        Corporation called to consider such matter in
        accordance with section 2 hereof.

    (h)      "Options" shall mean any stock options issued
        pursuant to the Corporation's Employee Stock Option
        Plan of 1988, Long-Term Incentive Award Plan of 1983,
        Stock Option Plan of 1978 or any future stock option
        plan.
    (i)      "Retirement" shall mean a termination of the
        Executive's employment after age 65 or in accordance
        with any mandatory retirement arrangement with
        respect to an earlier age agreed to by the Executive.
   
   (j)  "Stock Appreciation Rights" shall mean any stock
        appreciation rights issued pursuant to the
        Corporation's Employee Stock Option Plan of 1988,
        Long-Term Incentive Award Plan of 1983, Stock Option
        Plan of 1978 or any future stock appreciation rights
        plan.

2.      "Termination by the Corporation Due to Cause for
   Termination."
   If the Corporation desires to terminate the Executive's
   employment due to Cause for Termination, the Corporation
   shall first deliver a Notice of Termination to the
   Executive.  Thereafter, the Board of Directors at a
   meeting held not less than two weeks nor more than four
   weeks after the delivery of the Notice Of Termination
   shall consider whether cause for Termination exists.
   Cause for Termination shall not be deemed to exist under
   this Agreement unless and until the Board determines in
   good faith by the affirmative vote of not less than three-
   quarters of the entire membership of the Board that the
   Executive has engaged in conduct which is Cause for
   Termination.  Should the Board determine that Cause for
   Termination exists, the Board may at that time or during a
   period of two weeks thereafter terminate the Executive's
   employment due to Cause for Termination by adopting at
   such time or during such period by a similar three-
   quarters vote a resolution terminating the Executive's
   employment. If the Board fails to adopt within such two-
   week period a resolution terminating the Executive's
   employment, then the Corporation shall be deemed to have
   waived its right to terminate the Executive due to those
   circumstances which constituted the Cause for Termination
   previously found to exist by the Board.

 3.     Termination Payments Following Change-in-Control.

    (a)      If, during the term of this Agreement, a Change-
        in-Control shall have occurred and the Executive's
        employment with the Corporation shall be terminated

              (i)  due to the Executive's death,
        
              (ii)      by the Executive unless terminated
               for Good Reason for Termination, or
        
              (iii)     by the Corporation in accordance
               with section 2 hereof or for Disability or
               Retirement, then the Corporation shall have no
               obligations hereunder to the Executive and the
               only obligations of the  Corporation to the
               Executive shall be in accordance with any
               other employment agreement applicable to the
               Executive and the then various policies,
               practices and benefit plans of the
               Corporation.
   
   (b)  If during the term of this Agreement both a Change-in-
        Control shall have occurred and the Executive's
        employment with the Corporation shall have terminated
        other than under the circumstances above described in
        Subsection 3(a), then the Corporation shall pay or
        cause to be paid on or before the fifth day following
        the Date of Termination in cash to the Executive the
        following sums:
        
              (i)  any unpaid portion of the Executive's
               full base salary for the period from the last
               period for which the Executive was paid to the
               Date of Termination;
        
              (ii)      any then deferred portions of cash
               awards (including deferred awards which but
               for this provision would not be payable until
               subsequent to the Date of Termination) made to
               the Executive under the Executive incentive
               Compensation Plan; and
        
              (iii)     an amount as liquidated damages for
               lost future remuneration equal to the product
               obtained by multiplying

               (A)  the lesser of
                  
                    (1)     three or
                    
                    (2)     a number equal to the number of
                       calendar months remaining from the
                       Date of Termination to the date on
                       which the Executive is 65 years of age
                       (or, if earlier, the age agreed to by
                       the Executive pursuant to any prior
                       arrangement) divided by twelve
                    
                     times
             
                (B)      the sum of

                    (1)     the greater of
                  
                       (i)     the Executive's base salary
                           for the year in effect on the Date
                           of Termination (provided that in
                           the case of Termination for Good
                           Reason by the Executive the date
                           immediately preceding the date of
                           the earliest event which gave rise
                           to the Termination for Good Reason
                           by the Executive shall be used
                           instead of the Date of
                           Termination)
                       
                          or
                       
                       (ii)    the Executive's base salary
                           for the year in effect on the date
                           of the Change-in-Control;
                       
                       provided that "base salary for the
                       year" shall be the amount of base
                       salary for the year established by the
                       Board of Directors at the beginning of
                       the fiscal year in question in
                       accordance with the compensation
                       policies and practices of the
                       Corporation, without regard to any
                       reduction in the amount actually paid
                       to the Executive during such year as a
                       result of any plan of the Corporation
                       to reduce compensation due to economic
                       considerations, and without regard to
                       any deferral of compensation payable
                       to the Executive for services rendered
                       during such year to a subsequent year.

                           Executive the date immediately
                           preceding the date of the event

                           received by the Executive under
                           the Incentive Compensation Plan
                           for the two calendar years
                           immediately preceding the date of
                           the Change-in-Control.

   (c)  Notwithstanding any other provisions of this
        Agreement, in the event that any payment or benefit
        received or to be received by the Executive pursuant
        to the terms of this Agreement or otherwise
        (collectively the "Total Payments") would not be
        deductible, in whole or part, as a result of section
        280G of the Internal Revenue Code of 1986, as amended
        (the "Code") by the Corporation, an affiliate or
        other person making such payment or providing such
        benefit, the payments due under this Agreement (the
        "Contract Payments") shall be reduced until no
        portion of the Total Payments is not deductible, or
        the Contract Payments are reduced to zero.  For
        purposes of this limitation (i) no portion of the
        Total Payments the receipt or enjoyment of which you
        shall have effectively waived in writing prior to the
        date of payment of the Contract Payments shall be
        taken into account, (ii) no portion of the Total
        Payments shall be taken into account which in the
        opinion of tax counsel selected by the Corporation's
        independent auditors and acceptable to you does not
        constitute a "parachute payment" within the meaning
        of section 280G(b)(2) of the Code, (iii) the Contract
        Payments shall be reduced only to the extent
        necessary so that the Total Payments (other than
        those referred to in clauses (i) or (ii) in their
        entirety constitute reasonable compensation for
        services actually rendered within the meaning of
        section 280G(b)(4) of the Code or are otherwise not
        subject to disallowance as deductions, in the opinion
        of the tax counsel referred to in clause (ii); and
        (iv) the value of any non-cash benefit or any
        deferred payment or benefit included in the Total
        Payments shall be determined by the Corporation's
        independent auditors in accordance with the
        principles of sections 280G(d)(3) and (4) of the
        Code.
   
4.      Stock Appreciation Rights and Stock Options.

   (a)     If the Executive's employment should terminate
       under such circumstances as entitle the Executive to
       receive payments pursuant to section 3(b) hereof,
       then, in lieu of Stock Appreciation Rights granted to
       the Executive (and whether or not they are in tandem
       with any Options, but provided that this subsection
       shall not apply to any Stock Appreciation Rights in
       tandem with incentive stock options) that were
       outstanding for at least six months prior to the Date
       of Termination and that were neither subsequently
       exercised nor expired by their terms prior to the Date
       of Termination (which rights and any related in tandem
       options shall be cancelled upon the making of the
       payment hereafter described), the Executive shall
       receive an amount in cash on or before the fifth day
       following the Date of Termination equal to the
       difference, if positive, obtained by
   
              (i)  taking the product obtained by
               multiplying
            
               (A)  the number of such stock appreciation
                    rights
               
                times
                
               (B)  the greater of
                     
                    (1)     the mean between the highest and
                       lowest quoted selling prices for the
                       Corporation's common stock on the
                       composite tape for the New York Stock
                       Exchange on the trading day
                       immediately preceding the Date of
                       Termination;
                    
                       or
                    
                    (2)     the highest price paid per share
                       for the Corporation's common stock in
                       the transaction resulting in the
                       actual Change-in-Control.
                    
          and
       
              (ii)      subtracting therefrom the aggregate
               of the products obtained by multiplying the
               mean between the highest and lowest quoted
               selling prices for the Corporation's Common
               Stock on the composite tape for the New York
               Stock Exchange on each date of grant of such
               Stock Appreciation Rights times the number of
               such Stock Appreciation Rights granted on such
               date.
       
   (b)     If the Executive's employment should terminate
       under such circumstances as entitle the Executive to
       payments pursuant to Section 3(b) hereof then the
       Executive may elect, during the 60-day period from and
       after a Change of Control (other than a Change of
       Control initiated by the Executive), to surrender his
       rights in any of the options granted to the Executive
       provided that this subsection shall not apply to any
       Options accompanied by a Stock Appreciation Right that
       were outstanding for at least six months prior to the
       Date of Termination and that were neither subsequently
       exercised nor expired by their terms prior to the Date
       of Termination and, upon such surrender, the
       Corporation shall pay to the Executive an amount of
       cash with respect to each such option equal to the
       difference, if positive, obtained by
       
              (i)  taking the product obtained by
               multiplying
           
               (A)  the number of shares of common stock as
                    to which the option is exercisable
               
                    times
               
                (B)      the greater of
               
                    (1)     the mean between the highest and
                       lowest quoted selling prices for the
                       Corporation's Common Stock on the
                       composite tape for the New York Stock
                       Exchange on the trading day
                       immediately preceding the Date of
                       Termination
                    
                       or
                    
                    (2)     the highest price paid per share
                       for Corporation's Common Stock in the
                       transaction resulting in the actual
                       Change-in-Control
                    
                    and
       
              (ii)      subtracting therefrom the option
               price for such Shares of Common Stock.
   
   (c)     In the event the Executive's employment should
       terminate under such circumstances as entitle the
       Executive to payments pursuant to Section 3(b) hereof,
       the Corporation agrees to accelerate and make
       immediately exercisable in full all unmatured options
       held by the Executive at the Date of Termination,
       whether or not otherwise exercisable, effective as of
       the Date of Termination.  In the event that the
       Executive has been granted Incentive Stock Options
       pursuant to Section 422A(b)(7) of the Internal Revenue
       Code of 1986 (the "Code") which would otherwise become
       immediately exercisable hereunder but for the
       limitation imposed by Code Section 422A(b)(7), such
       options shall only become exercisable as to the
       maximum number of shares permitted by Code Section
       422A(b)(7) and the balance of such options shall
       become exercisable at the earliest date or dates
       thereafter permitted by Code Section 422A(b)(7), with
       those options with the lowest exercise prices becoming
       exercisable at the earliest date or dates.
 5.     Retirement Benefits.

    (a)      If the Executive's employment should terminate
        under such circumstances as entitle the Executive to
        receive payments pursuant to section 3(b) hereof,
        then, notwithstanding such termination, the Executive
        shall be deemed to continue as an active employee
        participant in the Corporation's pension plan for
        salaried employees, and the benefits payable to him,
        his surviving spouse or contingent annuitant shall be
        calculated as if he had been continuously employed by
        the Corporation for those years (including parts
        thereof) subsequent to the Date of Termination and
        prior to the earlier of (i) three years subsequent to
        the Date of Termination, and (ii) the Executive's
        death or attainment of age 65 (or, if earlier, the
        age agreed to by the Executive pursuant to any prior
        arrangement), at the covered remuneration set forth
        in the following sentences of this subsection.  The
        covered remuneration for any part of a year remaining
        after the Date of Termination shall equal the number
        of months remaining in such year times the sum
        determined pursuant to section 3(b)(iv)(B) hereof and
        divided by twelve. The covered remuneration for the
        first full credited year following the Date of
        Termination shall equal the sum determined pursuant
        to section 3(b)(iv)(B) hereof.  The covered
        remuneration for the first full credited year after
        the first full credited year shall equal the sum of
        (i) the covered remuneration for the immediately
        preceding year plus (ii) the product of the Annual
        Salary Adjustment percentage for such credited years
        times the covered remuneration for the immediately
        preceding year.
   
   (b)  If for any reason whether by law or the terms of the
        Corporation's pension plan, such pension plan cannot
        either use the above credited years of service and
        remuneration above described in subsection 5(a) for
        purposes of the Executive's pension benefits
        (including surviving spouse and contingent annuitant
        benefits) or cannot pay the full amount of benefits
        which would result from the foregoing subsections,
        then the Corporation hereby contractually agrees to
        pay the difference between
        
              (i)  the benefits which would be payable if
               the pension plan had been able to pay such
               benefits based upon the credited years of
               service and covered remuneration above
               described in subsection 5(a),
        
         and
        
              (ii)      the benefits, if any, actually paid
               to the Executive, his surviving spouse or
               contingent annuitant by the pension plan.
        
        The Corporation shall not be required to fund its
        obligation to pay the foregoing difference.

 6. Other Benefit Plans.

    (a)      If the Executive's employment should terminate
        under such circumstances as entitle the Executive to
        receive payments pursuant to section 3(b) hereof and
        if the Executive is a participant in the
        Corporation's Executive Benefit Plan (or a plan
        providing comparable benefits) shall be in effect
        prior to the Change-in-Control, then the Executive
        will be deemed for purposes of such Plan (or, if
        applicable, the plan providing comparable benefits)
        to have continuously remained in the employ of the
        Corporation until the earlier of (i) three years
        subsequent to the Date of Termination, and (ii) his
        death or attainment of age 65 (or the age agreed to
        by the Executive pursuant to any prior arrangement),
        at a total compensation equal to his total
        compensation in effect on the Date of Termination
        (provided that in the case of Termination for Good
        Reason by the Executive the date immediately
        preceding the date of the earliest event which gave
        rise to the Termination for Good Reason by the
        Executive shall be used instead of the Date of
        Termination) and to have made any required
        contributions due thereunder.  The Executive will be
        eligible to receive all benefits under such Plan (or,
        if applicable, the plan providing comparable
        benefits) payable as though he had so remained in the
        Corporation's employ and had made any required
        contributions notwithstanding that he neither was so
        employed nor made any such contributions.
   
   (b)  Except with respect to (i) any Stock Appreciation
        Rights and Stock Options, as to which payment is
        provided in Section 4(a) hereof, (ii) the
        Corporation's pension plan, which is governed by
        paragraph 5 hereof, (iii) the Executive Benefit Plan,
        and (iv) the Incentive Compensation Plan, the
        Executive shall be deemed for purposes of all
        employee benefits to have remained in the continuous
        employment of the Corporation for a period of three
        years following the Date of Termination and shall be
        entitled to all of the benefits provided by such
        plans as though he had so remained in the employment
        of the Corporation.
   
   (c)  If for any reason, whether by law or provisions of
        the Corporation's employee benefit plans, any
        benefits which the Executive would be entitled to
        under the foregoing subsections of this section 6
        cannot be paid pursuant to such employee benefit
        plans, then the Corporation hereby contractually
        agrees to pay to the Executive the difference between
        the benefits which the Executive would have received
        in accordance with the foregoing subsections of this
        section if the relevant employee benefit plan could
        have paid such benefit and the amount of benefits, if
        any, actually paid by such employee benefit plan.
        The Corporation shall not be required to fund its
        obligation to pay the foregoing difference.

 7.Other Employment.

    (a) The Executive shall have no duty to seek any other
        employment after termination of his employment with
        the Corporation and the Corporation hereby waives and
        agrees not to raise or use any defense based on the
        position that the Executive had a duty to mitigate or
        reduce the amounts due him hereunder by seeking other
        employment whether suitable or unsuitable.

   (b)  Should the Executive obtain other employment, then
        the only effect of such on the obligations of the
        Corporation hereunder shall be that the Corporation
        shall be entitled to credit against any payments
        which would otherwise be made pursuant to sections 5,
        6(a) or 6(b) hereof, any comparable payments to which
        the Executive is entitled under the pension or other
        employee benefit plans maintained by the Executive's
        other employers after termination of his employment
        with the Corporation.  In no event shall any sums
        received by the Executive from any other employment
        be credited against or otherwise reduce the amounts
        payable by the Corporation pursuant to Sections 3 or
        4 hereof.

 8.Term.

    (a)      This Agreement shall be for a term expiring
        August 31, 1998 and shall automatically be extended
        for successive five year terms at the end of each
        preceding term unless termination occurs pursuant to
        subsection (b) or (c) below, whichever is applicable.

    (b)      If a Change-in-Control has occurred, this
        Agreement shall remain in effect until terminated on
        the date which is three years from the Change-in-
        Control.

    (c)      If a Change-in-Control has not occurred, this
        Agreement shall terminate if the Executive's
        employment with the Corporation terminates for any
        reason whether such termination of employment is by
        the Corporation or by the Executive.  Otherwise,
        prior to a Change-in-Control, this Agreement may only
        be terminated by the Corporation upon the giving by
        the Corporation of notice of termination at least
        thirty days prior to the end of the then term, in
        which event this Agreement shall terminate at the end
        of such term.

 9. Miscellaneous.

    (a)      This Agreement shall be construed under the laws
        of the Commonwealth of Pennsylvania.
   
    (b)      This Agreement constitutes the entire
        understanding of the parties hereto with respect to
        the subject matter hereof and may only be amended or
        modified by written agreement signed by the parties
        hereto.
   
    (c)      The Corporation will require any successor
        (whether direct or indirect, by purchase, merger,
        consolidation or otherwise) to all or substantially
        all of the business and/or assets of the Corporation,
        by agreement in form and substance satisfactory to
        the executive, to  expressly assume and agree to
        perform this Agreement in the same manner required of
        the Corporation and to perform it as if no such
        succession had taken place.  Failure of the
        Corporation to obtain such agreement prior to the
        effectiveness of any such succession shall be a
        breach of this Agreement and shall entitle the
        Executive to terminate employment due to Good Reason
        for Termination. As used in this Agreement,
        "Corporation" shall mean the Corporation as
        hereinbefore defined and any successor to its
        business and/or assets as aforesaid which executes
        and delivers the agreement provided for in this
        subsection (c) or which otherwise becomes bound by
        all the terms and provisions of this Agreement by
        operation of law.
   
   (d)  This Agreement shall inure to the benefit of and be
        enforceable by the Executive or his legal
        representatives, executors, administrators,
        successors, heirs, distributees, devisees and
        legatees.  If the Executive should die while any
        amounts would still be payable to him hereunder if he
        had continued to live, all such amounts, unless
        otherwise provided herein, shall be paid in
        accordance with the terms of this Agreement to his
        devisee, legatee or other designee or if there be no
        such designee, to his estate.
   
   (e)  Any notice or other communication provided for in
        this Agreement shall be in writing and, unless
        otherwise expressly stated herein, shall be deemed to
        have been duly given if mailed by United States
        registered mail, return receipt requested, postage
        prepaid addressed
        in the case of the Executive to his office at the
        Corporation with a copy to his residence and in the
        case of the Corporation to its principal executive
        offices, attention of the Chief Executive Officer.
   
   (f)  No provisions of this Agreement may be modified,
        waived or discharged unless such waiver, modification
        or discharge is agreed to in writing signed by the
        Executive and approved by resolution of the Board of
        Directors of the Corporation.  No waiver by either
        party hereto at any time of any breach by the other
        party hereto of, or compliance with, any condition or
        provision of this Agreement to be performed by such
        other party shall be deemed a waiver of similar or
        dissimilar provisions or conditions at the same or at
        any prior or subsequent time.  Except for any
        employment agreement with the Executive, no
        agreements or representations, oral or otherwise,
        express or implied, with respect to the subject
        matter hereof have been made by either party which
        are not set forth expressly in  this Agreement.  To
        the extent that the provisions of this Agreement are
        in conflict with any such employment agreement,
        following a Change-in-Control the employment
        agreement shall automatically be amended in
        accordance with this Agreement and the provisions of
        this Agreement shall govern.
   
   (g)  The invalidity or unenforceability of any provisions
        of this Agreement shall not affect the validity or
        enforceability of any other provision of this
        Agreement, which shall remain in full force and
        effect.

   (h)  This Agreement may be executed in one or more
        counterparts, each of which shall be deemed to be an
        original but all of which together will constitute
        one and the same instrument.

     IN WITNESS WHEREOF, this Agreement has been executed on
the date first above written.

FINANCIAL REVIEW

OVERVIEW

Dravo Corporation's financial results following its first year
operating as a lime company were positive.  Demand was robust
throughout the year in most lime markets, and spot market pricing
was strong.  Earnings from continuing operations increased not
only compared to 1994's actual results, which included Dravo
Basic Materials (DBM), the construction aggregates operation that
was divested at the end of 1994, but on a pro forma basis as
well.  Dampening 1995 performance, however, were a series of
startup problems and delays encountered in connection with the
expansion of the company's Black River facility in northern
Kentucky.  Production levels and operational cost targets were
not met during the initial startup period.  However, toward the
end of the year and continuing through early 1996, production
rates and costs were more in line with expectations.

Progress continued in resolving discontinued operations issues.
A contract dispute with Continental Energy Associates (CEA)
related to CEA's Hazleton Gasification Facility was resolved.
The company paid $2.8 million as its share of the settlement. CEA
had claimed damages as high as $35 million.  The settlement was
within the amount provided in the previously established reserve
for discontinued operations for legal fees anticipated to
litigate the claim and, therefore, did not impact current
earnings.

Earnings for the year were $11.0 million, or $0.57 per share.  In
1994, Dravo reported a net loss of $10.6 million, or $0.88 per
share.  A charge to discontinued operations of $6.5 million was
recorded in 1994 for legal fees and to provide for the settlement
of a lawsuit brought in Venezuela for contract services provided
in the mid-1970s.  Also, an extraordinary charge of $7.6 million,
or $0.51 per share, was recorded to reflect the write-off of fees
associated with debt instruments that were prepaid or
substantially altered as a result of the DBM asset sale.  A one-
time charge of $1.4 million, or $0.09 per share, reflects the
cumulative accounting effect of the adoption of Statement of
Financial Accounting Standards No. 112, "Employers Accounting for
Postemployment Benefits."

In 1993, earnings from continuing operations were $35.1 million,
or $2.20 per share.  Included in the 1993 earnings results was a
$24.9 million deferred tax benefit.  Loss on discontinued
operations was $35.3 million, or $2.38 per share.  The net loss
of $177,000 equaled $0.18 per share after payment of preferred
dividends.









RESULTS OF OPERATIONS

CONTINUING OPERATIONS

Revenue: Revenue in 1995 was $146.1 million compared to $278.1
million in 1994, which included DBM for the entire year.  Lime
revenue in 1994 was $125.7 million.  The increased lime revenue
in 1995 was mainly due to first-year shipments to American
Electric Power's Gavin station under a 15-year supply contract.
Shipments under a new supply agreement with the Henderson
Municipal Power and Light Station operated by Big Rivers Electric
Cooperative and strong spot market pricing in 1995 also
contributed to the revenue increase.

Revenue of $278.1 million during 1994 was up slightly over 1993's
level.  Lime revenue of $125.7 million was down compared to 1993
due to price concessions granted in return for multi-year
extensions of long-term lime supply contracts and weather-related
problems in the first quarter.  The impact of these items was
partially mitigated, however, by increased demand for non-utility
lime in 1994.  Demand was especially strong for metallurgical
lime used in making steel and aluminum.

Costs and Expenses: Gross profit of $36.5 million was $7.5
million lower in 1995 than in 1994, which included DBM.  Margins,
however, were much improved: 25 percent in 1995 versus 16 percent
last year.  The improved margins reflect the dilutive effect the
aggregates business had on the company's margins before the
divestiture.  Gross margins on lime sales were slightly higher
than last year's pro forma results, but the increase was less
than expected because of start-up related production costs at
Black River.

Gross profit of $44.0 million in 1994 was down $5.3 million from
1993.  Lime and aggregates operations located in the Ohio River
Valley were negatively affected by a severe winter that caused
operating difficulties during the first quarter.  Price
concessions on long-term lime supply contracts impacted gross
profit, as did an unscheduled seven-week outage at one of the
company's electric utility customer's generating stations.
Production costs at the Black River operation were higher as
personnel were added in preparation for expanded underground
mining and start-up of the two new lime kilns.  Also, the write-
off of equipment being replaced as part of the plant expansion
and modernization project affected profit margins.
                             -12-
<PAGE>                       
Selling expense of $5.0 million was lower primarily due to the
DBM sale.  Selling expense also varies due to amounts of research
and development expense that can be billed to third parties.
These research activities involve a variety of lime-related
technologies, with particular emphasis on air pollution control.
Depending on the project, reimbursement may be made by
governmental agencies, public utilities or private groups for all
or a portion of project costs.  Research and development costs
and billings to third parties are detailed in Note 16, Research
and Development, in the Notes to Consolidated Financial
Statements.

General and administrative expenses were $6.3 million lower in
1995 than last year due to personnel reductions following the DBM
sale and consolidation of the company's administrative functions
at Dravo's Pittsburgh headquarters.  On a pro forma basis,
administrative expenses were higher because of differences
between actual experience and the assumptions used in preparing
the pro forma analysis.  Expenses in 1994 were reduced by more
than six percent from 1993.  The reduction reflects lower
staffing levels, employee and retiree medical expenses, and
travel expenses, as well as lower charges related to the
amortization of a non-cancelable lease obligation on a downtown
Pittsburgh office building.

Equity in earnings of joint ventures includes, in 1995, the
company's share in two 50-percent owned joint ventures: a
contract phosphate rock mining operation in Idaho and a small
contract coke operation in Wyoming.  Prior to 1995, the company
also had a 50-percent share in a shell dredging operation located
off the Louisiana coast.  Earnings from joint ventures were down
$1.1 million from 1994 due to higher maintenance expense at the
Idaho facility and the sale of the shell dredging operation as
part of the DBM transaction.  In 1994, results for the shell
dredging operation were significantly improved over 1993.  The
phosphate mining operation's profitability varies depending on
mining conditions and its single contract customer's
requirements.  Strong demand led to improved results in 1994 over
1993.

Other income includes the gain on the sale of property, plant and
equipment.  In 1995, the amount is insignificant.  The $1.1
million gain in 1994 includes the sale of the company's airplane,
$324,000, and $487,000 from the sale, after accrued expenses, of
DBM's assets.  See Note 3, Dispositions, in the Notes to
Consolidated Financial Statements for a further discussion of the
DBM sale transaction.  In 1993, a gain was recognized on the sale
of property in Baton Rouge, Louisiana, and excess floating
equipment, mainly barges.

The decline in interest income from 1994 reflects the collection,
early in 1995, of an interest bearing note receivable.  In 1994,
interest income was lower due to a lower balance on this same
note receivable and the cessation of an interest accrual on
another note.

Interest expense of $4.8 million in 1995 was significantly lower
than 1994's expense of $12.4 million.  The reduction reflects
lower debt levels as the company prepaid $85.5 million of loans
early in 1995 from cash received from the DBM transaction.  Lower
interest rates and the capitalization of interest associated with
the Black River expansion also lowered expense.  Interest expense
in 1994 was $3.2 million higher than 1993.  The higher expense
was due to higher interest rates on a prime rate-based line of
credit and fees paid to a prospective lender whose participation
in the Black River financing package was terminated by the
company.  Capitalized interest on major capital projects amounted
to $2.8 million and $1.4 million in 1995 and 1994, respectively.
No interest was capitalized in 1993.

Income tax expense of $340,000 represents an accrual for state
income taxes.  Significant net operating loss carryforwards
(NOLs) exist that shelter the company's income from most federal,
and some state, income taxes.  In 1994, income tax expense of
$597,000 included an accrual of $300,000 for federal alternative
minimum tax arising from the sale of DBM assets.  In 1993, a
benefit for income taxes of $24.9 million was recorded under the
provisions of Statement of Financial Accounting Standards No. 109
(SFAS 109), "Accounting for Income Taxes."  Management believes
that, due to the large proportion of revenue generated by long-
term supply contracts, income can be reasonably projected for
purposes of determining whether the realization of the asset
resulting from the utilization of NOLs in future years is more
likely than not.  The amount of the net deferred tax asset
reflects that portion of the gross deferred tax asset that
management believes, based on current projections and estimates,
is more likely than not to be realized.  After the recognition of
all NOLs have been reflected in the consolidated financial
statements, the company's tax rate will return to a more normal,
higher effective rate

In conjunction with the sale of DBM's assets, existing loan
agreements were substantially altered, including a $35 million
reduction in the amount available under a revolving credit
facility.  Also, while negotiating a $50 million financing
agreement with Prudential Power Funding for the Black River
expansion, the company purchased a call option that enabled it to
prepay on May 17, 1995, without penalty, amounts outstanding
under the financing agreement.  With Prudential Power Funding's
consent, the entire amount borrowed was prepaid.  The fees
associated with these agreements were written off as
extraordinary items in 1994.
                              -13-
<PAGE>
Effects of inflation:  Inflation rates have been low over the
past three years and as a result have not had a significant
effect on the company's operations. In addition, Dravo Lime's
long-term lime supply contracts provide for price increases for
specific production expenses, such as labor, fuel and
electricity.


DISCONTINUED OPERATIONS

A contract dispute with Continental Energy Associates (CEA) was
resolved in 1995.  The company's share of the settlement, $2.8
million, did not necessitate an additional provision for
discontinued operations.  In 1994, a previously established
provision for discontinued operations was increased $6.6 million.
The additional charge was taken to cover a $4.5 million
settlement involving an alleged breach of contract by the company
for work performed between 1973 and 1978 in Venezuela.  The
balance of the provision was, for the most part, estimated legal
fees for the CEA dispute and an insurance claim.  As noted, the
CEA dispute was subsequently settled.  The second matter involves
the company's assertion that it is entitled to a defense and
indemnity under its contracts of insurance for environmental
clean-up costs in Hastings, Nebraska.  See Note 8, Contingent
Liabilities, in the Notes to Consolidated Financial Statements
for a further discussion of the Hastings matter.

In 1993, a $35.3 million charge was recorded.  The provision was
primarily to cover a settlement agreement with the City of Long
Beach, California, which included the company giving up its claim
to unpaid receivables and interest totaling $18 million.  The
provision also recognized an increase in the estimated
environmental clean-up costs at the Hastings superfund site,
write-off of a note receivable due to an unfavorable court ruling
and additional legal fees.


FINANCIAL POSITION AND LIQUIDITY

Significant changes on the company's balance sheet from December
31, 1994 to year-end 1995 resulted principally from the
collection of a $120.5 million receivable from Martin Marietta
Materials, Inc. (Martin Marietta) relating to the sale of DBM.
The company completed negotiations on December 30, 1994 for the
sale of substantially all the assets and certain liabilities of
DBM to Martin Marietta effective January 3, 1995.  The balance
sheet at December 31, 1994, reflected the effect of the sale
transaction, in that the assets and liabilities sold were removed
and a $120.5 million receivable from Martin Marietta recorded.
In early 1995, the receivable was satisfied with cash, a portion
of which was used to prepay $85.5 million of debt.  The
substantial reduction in accounts payable resulted from the
satisfaction of DBM payables outstanding at December 31, 1994.

Long-term debt increased $21.8 million from year-end 1994 due to
$27.9 million borrowed under a revolving credit facility,
partially offset by $6.1 million reclassified from long-term debt
to a current obligation.  The increase in the outstanding debt
under the revolving credit facility is due primarily to funding
the Black River expansion project.

The company has sufficient funds and borrowing capacity to meet
its anticipated operating and capital needs.  To minimize
interest charges, cash balances are kept low through a banking
arrangement that uses excess cash held in the company's accounts
to reduce the amount of overnight borrowing on the revolving
credit agreement.

Effective October 1, 1995, a revolving credit/letter of credit
facility provided by a consortium of lenders that includes First
Alabama Bank; PNC Bank, N.A.; and Bank of America Illinois was
increased to $65 million.  Interest on the revolver equals either
the base lending rate of Regions Financial Corporation, First
Alabama Bank's parent, or, at the option of the company, the
Eurodollar interest rate plus two percent.  The facility expires
July 31, 1997, but includes renewal provisions.

The company intends to use a portion of the line of credit to
finance construction of a new kiln and related material-handling
equipment at its Maysville facility.  On July 31, 1997, up to $17
million borrowed under the facility may be converted to a five-
year term loan.  Also on July 31, 1997, the amount available
under the revolver will be reduced from $65 million to $45
million.

Obligations under the revolving credit/letter of credit facility
and senior term notes are secured by a pledge of the stock of
Dravo Lime Company and Dravo Basic Materials Company along with
Dravo Lime Company's accounts receivable and finished goods
inventories.  Additionally, certain contract rights, patents and
mortgages on the company's Maysville, Black River and Longview
plants have been pledged as collateral.  The agreements contain
uniform restrictive covenants that require the company to
maintain minimum net worth levels and fixed charge ratios on a
consolidated basis; restrict incurrence of debt, liens and lease
obligations; restrict the sale of significant assets; and limit
payment of dividends.  These restrictions are not expected to
have an adverse impact on the company's ability to meet its
obligations.

All known outstanding discontinued operations items have been
classified as current or long-term based on the estimated timing
of future cash receipts and disbursements.  The discontinued
operations liabilities do not have a material adverse impact on
liquidity because cash payments needed to satisfy them are spread
over several years.
                               -14-
<PAGE>
In January, 1995, the Board of Directors approved a program
whereby the company was authorized to purchase up to 250,000
shares of its common stock on the open market.  During the year,
over 228,000 shares were repurchased.  The shares are being held
in the treasury and will be used for general corporate purposes.


DIVIDENDS

The company's loan agreement contains a covenant that limits
common stock dividend payments.  A common stock dividend may not
be declared if that dividend plus all other common dividends paid
after September 30, 1995, exceeds 25 percent of cumulative
earnings from continuing operations after September 30, 1995.
Cumulative earnings exclude gains from the sale of capital
assets, extraordinary gains and unremitted earnings of joint
ventures. At December 31, 1995, cumulative earnings since
September 30, 1995, from which dividends could be declared
totaled $2.8 million.  No dividends on common stock were
declared.  Dividends on the $3.0875 cumulative, convertible,
exchangeable, Series D Preference Stock and the $2.475 cumulative
convertible Series B Preference Stock were declared quarterly
throughout each of the last three years.  All declared preference
dividends have been paid on a timely basis.


COMMON STOCK MARKET PRICE

The principal market on which Dravo's common stock is traded is
the New York Stock Exchange under the symbol, DRV.  The high and
low common stock sales prices for each quarterly period in 1995
and 1994 as reported for New York Stock Exchange composite
transactions were:

OUTLOOK

Continuing operations: Dravo Corporation successfully completed
its first year operating as a lime business.  With over two-
thirds of production capacity committed under long-term utility
and merchant lime contracts, and the balance expected to be sold
into strong spot markets, the company foresees building on the
progress made in 1995.

A major expansion at Black River, despite delays and start-up
problems, is now performing at the level envisioned in the
project design.  The next major capital project, the installation
of a new kiln and related material-handling equipment at the
company's Maysville, Kentucky, facility, is scheduled for
completion in early 1997.  The project will cost approximately
$20 million and will add 350,000 tons of annual capacity.  A
smaller, but important project, will be the refurbishing of an
older-existing kiln at Black River.  The project will increase
production of the kiln while significantly reducing its
production costs.

The Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-
Based Compensation" (SFAS 123) in October, 1995.  Financial
statements presented for fiscal 1996 will measure the fair value
of stock-based compensation awarded to employees in 1995 and
thereafter.  SFAS 123 allows companies a choice between
continuing to account for stock-based awards using the intrinsic
value, as prescribed by Accounting Principles Board Opinion No.
25 (APB 25), or the fair value.  If the company chooses to
continue following APB 25, the pro forma effect the fair value
methodology would have had on net income and earnings per share
will be disclosed.  The company has not yet determined the
magnitude of the difference between the intrinsic value and fair
value approaches nor the method it will choose to account for
stock-based compensation.

The FASB also issued SFAS 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of"
(SFAS 121).  SFAS is effective for fiscal years beginning after
December 31, 1995.  The effect of adopting SFAS 121 will be
immaterial to the company.

Discontinued operations:  The company formerly operated a metal
fabrication facility in Hastings, Nebraska.  The federal
Environmental Protection Agency (EPA) has notified the company it
believes the company is a potentially responsible party (PRP) for
the clean-up of soil and groundwater contamination at four sub-
sites in the Hastings area.  See Note 8, Contingent Liabilities,
in the Notes to Consolidated Financial Statements for further
discussion of the company's estimate of total clean-up costs and
its share of those costs.

Management believes the provision for losses on discontinued
operations is adequate at this time.  However, in establishing
the provision and monitoring it, the costs of exiting
discontinued businesses and pursuing the company's rights through
litigation were estimated.  A ruling by the courts or a
settlement of the disputes that is adverse to Dravo's position,
or other unforeseen developments, could require a future
additional provision for discontinued operations.

company  has  long-term contracts, each accounted  for  more
than 10 percent of consolidated revenue in 1995. The company
completed  a  transaction on December 30, 1994 in  which  it
sold substantially all the assets and certain liabilities of
Dravo   Basic  Materials  Company,  Inc.  (DBM),  a   former
principal subsidiary.  The assets and liabilities  sold  are
removed  from  the  company's December  31,  1995  and  1994
consolidated balance sheets.  The December 31, 1994 and 1993
consolidated   statements  of  operations  and  consolidated
statements of cash flows include the results of DBM for  the
entire year.

Principles   of  Consolidation:   Significant   intercompany
balances  and  transactions  have  been  eliminated  in  the
consolidation process.

Use  of  Estimates:  The preparation of financial statements
in  conformity with generally accepted accounting principles
requires  management to make estimates and assumptions  that
affect  the  reported amounts of assets and liabilities  and
disclosure of contingent assets and liabilities at the  date
of  the  financial  statements and the  reported  amount  of
revenues  and expenses during the reporting period.   Actual
results could differ from those estimates.

Cash  and Cash Equivalents:  For purposes of reporting  cash
flows,   the  company  considers  all  highly  liquid   debt
instruments  purchased with a maturity of  three  months  or
less to be cash equivalents.

Inventories:   Inventories are valued at average  production
cost  or  market, whichever is lower.  The cost of  products
produced  includes raw materials, direct labor and operating
overhead.

Property,  Plant,  Equipment  and  Depreciation:   Property,
plant  and  equipment  are stated  at  cost.   The  cost  of
buildings,  equipment  and  machinery  is  depreciated  over
estimated   useful   lives   on   a   straight-line   basis.
Expenditures  for  maintenance  and  repairs  which  do  not
materially   extend  the  lives  of  assets   are   expensed
currently.  The asset cost and accumulated depreciation  are
removed  from  the accounts for assets sold or retired,  and
any  resulting gain or loss is included in other income  and
expense.

           Notes to Consolidated Financial Statements


Note   1:   Summary   of  Significant  Accounting   Policies
(continued)

Income  Taxes:   Deferred  income  taxes  reflect  the   tax
consequences on future years of differences between the  tax
bases   of   assets  and  liabilities  and  their  financial
reporting  amounts.   Future  tax  benefits,  such  as   net
operating  loss carryforwards, are recognized to the  extent
that realization of such benefits are more likely than not.

Earnings Per Share:  Primary earnings per share are based on
net earnings less preference dividends declared in the year,
divided  by  the  weighted  average  sum  of  common  shares
outstanding  during  the year and common share  equivalents.
Shares  exercisable  as  employee stock  options  and  stock
appreciation rights are considered common share  equivalents
except when their inclusion would be anti-dilutive.  Primary
common share equivalents are calculated based on the average
common stock price for the year.  Fully diluted earnings per
share  are based on net earnings, divided by the sum of  the
weighted average number of common shares outstanding  during
the  year, weighted average number of shares resulting  from
the assumed conversion of issued preference shares to common
shares  and common share equivalents.  Fully diluted  common
share equivalents are calculated based on the higher of  the
average  or  ending common stock price for the year.   Fully
diluted  earnings per share are anti-dilutive in 1995,  1994
and 1993 and are not presented.

Note 2:  Discontinued Operations

In December, 1987, Dravo's Board of Directors approved a
major restructuring program which concentrated the company's
future direction exclusively on opportunities involving its
natural resources business.  An additional charge of $6.5
million was taken in 1994 for discontinued operations.  The
charge included $4.5 million to settle a claim that alleged
the company breached a contract relating to engineering and
procurement services rendered between 1973 and 1978 for a
sugar cane processing facility in Venezuela.  The provision
also included amounts for legal fees anticipated to pursue
                               -22-
<PAGE>

various lawsuits and claims, the most significant being the
Hastings insurance litigation discussed in Note 8,
Contingent Liabilities, and a contract dispute with
Continental Energy Associates (CEA).  The CEA dispute was
settled in 1995 and did not exceed the amount provided in
the discontinued operations provision.

A $35.3 million provision for discontinued operations
expenses was recorded in 1993. The provision covered the
write-off of receivables and accrual of a settlement
relating to a resource recover facility built in Long Beach,
California; updated estimates of the potential costs to
clean-up soil and groundwater contamination at a former
operation located in Hastings, Nebraska; write-down of a
receivable from a Portland, Maine, utility to reflect a jury
award; and estimated legal fees.

The company received cash proceeds of $2.2 million in 1995,
$1.6 million in 1994 and $2.0 million in 1993 from the
repayment of notes received from the previous sales of
discontinued businesses.

The remaining discontinued operations' assets and
liabilities for the respective years ended December 31
relate to non-cancelable leases, environmental, insurance,
legal and other matters associated with exiting the
engineering and construction business and are presented
below:

Note 3:  Dispositions

The company completed a transaction on December 30, 1994 in which
it sold to Martin Marietta Materials, Inc. (Martin Marietta),
effective January 3, 1995, substantially all the assets of its
construction aggregates business.  Assets sold included the
assets, properties and leases of Dravo Basic Materials Company,
Inc. (DBM), a wholly owned subsidiary of the company, and
Atchafalaya Mining Company, Inc. (AMC), a wholly owned subsidiary
of DBM, used in the production, marketing, distribution and sale
of various aggregate products.  Also sold was the capital stock
of Dravo Bahama Rock Limited (DBR), a wholly owned foreign
subsidiary of DBM.

The company, DBM and AMC retained substantially all obligations
and liabilities which arose from, or in connection with,
operations prior to the sales transaction.  After expenses, a net
pre-tax gain of $487,000 was recorded as other income.

The assets and liabilities sold to Martin Marietta were removed
from the company's December 31, 1994 balance sheet, and a
corresponding receivable from the sale of DBM of $120.5 million
was recorded.  The December 31, 1994 consolidated statement of
operations includes the results of DBM for the entire year.

The following pro forma consolidated statement of operations
presents the results of operations assuming the disposition of
DBM had been completed as of the beginning of 1994. Adjustments
have been made to exclude the results of DBM, to decrease
interest expense for loans prepaid in early 1995 from the sale
proceeds, and to record interest income at overnight investment
rates for cash assumed to have been received in excess of
liabilities paid.  Pro forma data is provided for comparative
purposes only and does not purport to be indicative of the
results which actually would have been obtained if the
disposition had taken place prior to the pro forma dates.

</TABLE>

The following is a description of the terms and conditions
of the company's major debt instruments:

The $27.9 million note payable was borrowed under a $65.0
million revolving credit/letter of credit facility with
First Alabama Bank; PNC Bank, N.A.; and Bank of America
Illinois.  Interest on the revolver equals either the base
lending rate of Regions Financial Corporation, First Alabama
Bank's parent, or , at the option of the company, the
Eurodollar interest rate plus two percent.  The facility
expires July 31, 1997, but includes renewal provisions.

The company intends to use a portion of the line of credit
to finance construction of a new kiln and related material-
handling equipment at its Maysville facility.  On July 31,
1997, up to $17.0 million borrowed under the facility may be
converted to a five-year term loan.  Also on July 31, 1997,
the amount available under the revolver will be reduced from
$65.0 million to $45.0 million.

The variable rate note, 9.95 percent promissory notes and
10.13 percent construction notes were prepaid early in 1995
from a portion of the Dravo Basic Materials sale proceeds.

The 11.21 percent term notes require quarterly interest
payments and annual principal repayments in the amount of
$6.0 million beginning January, 1996.

Obligations under the revolving credit/letter of credit
facility and the 11.21 percent term notes are secured by a
pledge of the stock of Dravo Lime Company and Dravo Basic
Materials Company along with Dravo Lime Company's accounts
receivable and finished goods inventories.  Additionally,
certain contract rights, patents and mortgages on the
company's Maysville, Black River and Longview plants have
been pledged as collateral.  The agreements contain uniform
restrictive covenants that require the company to maintain
minimum net worth levels and fixed charge ratios on a
consolidated basis; restrict incurrence of debt, liens and
lease obligations; restrict the sale of significant assets,
and limit payment of dividends.  The company may not declare
a common stock dividend if that dividend plus all other
common dividends paid after September 30, 1995, exceed 25
percent of cumulative earnings from continuing operations
after September 30, 1995.  Cumulative earnings exclude gains
from the sale of capital assets, extraordinary gains and
unremitted earnings of joint ventures.  At December 31,
1995, cumulative earnings since September 30, 1995, from
which dividends could be declared totaled $2.8 million.  No
dividends on common stock were declared.
<PAGE>

Assets pledged under certain notes and leases had a book
value of $133.4 million at December 31, 1995.

In February, 1993, the company entered into an interest rate
swap agreement with Continental Bank, N.A. on the $41.8
million fixed rate long-term notes payable.  The transaction
was accounted for as a hedge of those notes.  On December
30, 1994, the company paid $1.4 million to terminate the
swap agreement.

Amounts payable on long-term debt due in 1996 and thereafter
are: 1996, $6.1 million; 1997, $6.1 million; 1998, $6.1
million; 1999, $6.0 million; 2000, $6.0 million; and after
2000, $12.1 million.

Note 6:  Redeemable Preference Stock

The  company  has outstanding 200,000 shares of  cumulative,
convertible,   exchangeable,  Series  D  Preference   Stock.
Cumulative  dividends  of  $3.0875  per  share  are  payable
quarterly.  Each share of preference stock may be converted,
at  the  option  of  the holder, into 8.0 shares  of  common
stock. The stock is also exchangeable, at the option of  the
company,  for 12.35 percent Senior Subordinated  Convertible
notes  due  September  21, 2001.  The 12.35  percent  Senior
Subordinated Notes would contain the same conversion rights,
restrictions and other terms as the preference stock.

The  company  may redeem the Series D Preference  Stock,  in
whole or in part, after January 21, 1996, for $100 per share
plus  accrued dividends, provided that the market  price  of
common  stock as of the date of the decision to  redeem  the
shares,  as  defined  in  the Certificate  of  Designations,
Preferences  and  Rights for the Series D Preference  Stock,
shall  be  at  least equal to 175 percent of the  conversion
price for the preference stock.  Mandatory annual redemption
of  the lesser of 50,000 shares or the number of shares then
outstanding  begins September 21, 1998, at  $100  per  share
plus accrued dividends.  In the event of liquidation of  the
company,  the  holders of outstanding  Series  D  Preference
Stock  shall be entitled to receive a distribution  of  $100
per share plus all accumulated and unpaid dividends.

The  company  had  outstanding 25,386 and 28,386  shares  of
cumulative,  convertible  Series  B  Preference   Stock   on
December 31, 1995 and 1994, respectively.  Cumulative annual
dividends  of $2.475 per share are payable quarterly.   Each
share  of Series B Preference Stock may be converted at  the
option  of  the holder to 3.216 shares of common stock.   In
the  event of the company's liquidation, the holders of  the
Series B Preference Stock are entitled to $55 per share plus
all accumulated and unpaid dividends.

Note 7:  Commitments

Total  rental  expense for 1995, 1994,  and  1993  was  $3.1
million, $35.2 million and $34.4 million, respectively.  The
minimum gross rentals under non-cancelable operating  leases
for  these years were $13.0 million, $17.3 million and $17.5
million,  respectively.   Of these amounts,  $10.5  million,
$10.5  million  and $10.4 million in 1995,  1994  and  1993,
respectively,   were  provided  for  in   the   discontinued
operations provision.

The  minimum  future rentals under non-cancelable  operating
leases  and future rental receipts from subleases  to  third
parties  as  of  December  31, 1995  are  indicated  in  the
following table.  Of the $10.7 million net minimum payments,
$5.6  million relates to, and has been expensed as part  of,
discontinued operations.

A  joint  venture phosphate mining operation, in  which  the
company is a 50 percent partner, has credit available  under
a  bank loan agreement for equipment purchases.  The company
would be required to repay the entire loan in the event of a
failure of both the joint venture and the other partner.  At
December  31, 1995 and 1994, $4.6 million and $2.9  million,
respectively, was borrowed under the agreement.

At  December  31, 1995 and 1994, the company had outstanding
letters  of  credit totaling $5.0 million and $7.5  million,
respectively.

Note 8:  Contingent Liabilities

The company has been notified by the federal Environmental
Protection Agency (EPA) that the EPA believes the company is a
potentially responsible party (PRP) for the clean-up of soil and
groundwater contamination at four sub-sites in Hastings,
Nebraska.  The Hastings site is one of the EPA's priority sites
for taking remedial action under the Comprehensive Environmental
Response, Compensation and Liability Act (CERCLA).

At one of these sub-sites, a municipal landfill, the company
believes it could not have disposed of hazardous wastes at the
particular sub-site because the landfill was
                                -25-
<PAGE>
closed prior to the
time the company and its predecessor initiated the operation
which generated the type of hazardous substances found at this
sub-site.  Other PRPs, including the local municipality, have
agreed to perform the remedial investigation and to design soil
and groundwater remedies at this sub-site.  The company has
agreed to participate in an EPA-initiated allocation proceeding
for this sub-site.

The company has also been notified by the EPA that the EPA
considers it a PRP at another municipal landfill in Hastings.  At
least three other parties (including the City of Hastings) are
considered by the EPA to be PRPs at this second sub-site.  At
this sub-site, the company has concluded that the City of
Hastings is responsible for a proper closure of the landfill and
the remediation of any release of hazardous substances.  In
January, 1994, EPA invited the company and the other PRPs to make
an offer to conduct a remedial investigation and feasibility
study (RI/FS) of this sub-site and stated that the EPA was in the
process of preparing a work plan for the RI/FS.  None of the PRPs
has volunteered to undertake the RI/FS.

With respect to the third sub-site, the company and two other
PRPs have been served with administrative orders directing them
to undertake soil remediation and interim groundwater remediation
at that sub-site.  The company is currently complying with these
orders while reserving its right to seek reimbursement from the
United States for its costs if it is determined it is not liable
for response costs or if it is required to incur costs because of
arbitrary, capricious or unreasonable requirements imposed by the
EPA.

The EPA has taken no legal action with respect to its demand that
the company and the other PRPs pay its past response costs.  A total
of five parties have been named by the EPA as PRPs at this sub-
site, but two of them have been granted de minimis status.  The
company believes other persons should also be named as PRPs.

The fourth sub-site is a former naval ammunition depot which was
subsequently converted to an industrial park.  The company and
its predecessor owned and operated a manufacturing facility in
this industrial park.  To date, the company's investigation
indicates that it did not cause the release of hazardous
substances in this sub-site during the time it owned and operated
the facility. The United States has undertaken to conduct the
remediation of this sub-site.

In addition to sub-site clean-up, the EPA is seeking a clean-up
of area-wide contamination associated with all of the sub-sites
in and around Hastings, Nebraska.  The company, along with other
Hastings PRPs, has recommended that the EPA adopt institutional
controls as the area-wide remedy in Hastings.  The EPA has
indicated some interest in this proposal but has decided to first
conduct an area-wide remedial investigation before choosing a
remedy.

On August 10, 1992 the company filed suit in the Alabama District
Court against its primary liability insurance carriers and one of
its predecessor's insurers, seeking a declaratory judgment that
the company is entitled to a defense and indemnity under its
contracts of insurance (including certain excess policies
provided by one of the primary carriers) with regard to the third
Hastings sub-site.  The company has settled the claim against its
predecessor's insurer, but the case against the company's
insurers is still in litigation.  An award of punitive damages is
also being sought against the company's insurers for their bad
faith in failing to investigate the company's claim and/or
denying the company's claim.  The company has notified its
primary and excess general liability carrier, as well as the
excess carrier of its predecessor, of the receipt of its notice
of potential liability at the first, second and fourth sub-sites.

Estimated total clean-up costs, including capital outlays and
future maintenance costs for soil and groundwater remediation of
approximately $18 million, are based on independent engineering
studies.  Included in the discontinued operations provision is
the company's estimate that it will participate in 33 percent of
these remediation costs.  The company's estimated share of the
costs is based on its assessment of the total clean-up costs, its
potential exposure, and the viability of other named PRPs.

Other claims and assertions made against the company will be
resolved, in the opinion of management, without material
additional charges to earnings.

The company has asserted claims that management believes to be
meritorious, but no estimate can be made at present of the timing
or the amount of recovery.

Note 9:  Retirement Plans

The   company   has  several  defined  benefit   plans   covering
substantially all employees.  Benefits for the salaried plan  are
based  on  salary  and years of service, while hourly  plans  are
based on negotiated benefits and years of service.  The company's
funding  policy  is  to make contributions as  are  necessary  to
provide assets sufficient to meet the benefits to be paid to plan
members  in  accordance  with the requirements  of  the  Employee
Retirement Income Security Act of 1974.  Plan assets are composed
primarily  of  government  securities  and  corporate  debt   and
equities.

The sale of Dravo Basic Materials' assets resulted in the termination
of  employment  for essentially all Dravo Basic Materials  employees
and  certain executive and administrative employees of a  subsidiary
company.   As a result, the company recognized a charge in 1994  for
pension  curtailment and special termination benefits expense.   The

Note 10:  Postretirement and Postemployment Benefits

The  company provides health care and life insurance benefits for
retired  employees.   Employees may become eligible  for  certain
benefits  if  they meet eligibility qualifications while  working
for  the company. Previously, the company paid all cost increases
for employees who retired prior to 1985 and who did not elect  to
participate  in  a  plan in which they paid  cost  increases,  in
exchange for expanded benefits, in excess of a specified  amount.
For  employees  retiring after 1984, the company's liability  was
limited  to  a fixed contribution amount for each participant  or
dependent.   Recently, the company communicated to all  Medicare-
eligible  retirees that, commencing in 1996, it will  participate
in  various Medicare HMOs.  The retiree will have the  option  of
joining  a  Medicare  HMO or selecting other health  care  plans;
however,  the company will contribute a fixed amount  toward  the
cost  of  the  coverage  regardless of the  plan  selected.   The
accumulated postretirement benefit obligation (APBO) at  December
31,  1995,  as  presented in the following  table,  reflects  the
implementation of this initiative.

The provisions of Statement of Financial Accounting Standards No.
106,  "Employers'  Accounting for Postretirement  Benefits  Other
Than  Pensions,"  were adopted effective January  1,  1993.   The
company accrues for the expected cost of providing postretirement
benefits  to
                              -27-
<PAGE>
the  employee and the employee's beneficiaries  and
covered  dependents  during  the  years  of  employment  service.
Expense  in  1994 includes a $471,000 curtailment loss  resulting
from  the  termination of essentially all Dravo  Basic  Materials
employees and certain executive and administrative employees of a
subsidiary company due to the Dravo Basic Materials asset sale.

No  funds  are  segregated for future postretirement obligations.
The  company is amortizing its accumulated postretirement benefit
obligation (APBO) over a 20-year period.  The APBO was calculated
using  a  discount  rate of 7.25 percent and a health  care  cost
trend  rate of 9.0 percent in 1996, gradually declining  to  5.25
percent in 2001.  An increase in the health care cost trend  rate
of  one percent would increase the APBO at December 31, 1995,  by
$331,000  and  the total service and interest rate components  of
the 1995 postretirement benefit cost by $90,000.

Postretirement benefit cost for 1995, 1994 and 1993 includes  the
following components:

The  company  adopted  the provisions of Statement  of  Financial
Accounting   Standards  No.  112,  "Employers'   Accounting   for
Postemployment  Benefits" (SFAS 112) effective January  1,  1994.
SFAS  112  requires  accrual of the estimated  cost  of  benefits
provided  by  the  employer  to  former  or  inactive  employees,
including  their  beneficiaries  and  covered  dependents,  after
employment  but before retirement.  A charge of $1.4 million  was
recorded in the first quarter as a cumulative effect for a change
in  accounting  principle  to recognize the  company's  estimated
liability for postemployment benefits covered by SFAS 112.

Note   11:    Stock  Options,  Stock  Appreciation   Rights   and
Performance Shares

The  company  has  outstanding to executives  and  key  employees
common stock options and stock appreciation rights (collectively,
rights) under four plans: the 1978 Plan, the 1983 Plan, the  1988
Plan  and the 1994 Plan.  Under the 1988 and 1994 Plans,  options
may  be  granted  either alone or in tandem  with  related  stock
appreciation rights, or stock appreciation rights may be  granted
separately.  The 1983 Plan provided for the granting of  options,
stock  appreciation rights (either separate or in tandem  with  a
related  option)  and performance shares.   The  price  of  stock
options and the basis of stock appreciation rights so granted  is
the  fair  market value on the date of grant.  Rights  cannot  be
exercised  until  one year after the grant date  and  expire  ten
years  from  date  of  grant.   Any incremental  value  of  stock
appreciation rights and performance shares granted is  recognized
as  expense, while a decline in the market value of the stock  is
recognized  as  a  reduction in expense to the extent  previously
recognized.  There was no change in the incremental value  during
the   last  three  years.   The  exercise  of  options  does  not
necessitate a charge or credit to income.

No  additional  grants can be made from the 1978 or  1983  Plans,
both  of  which  have expired.  There were no performance  shares
outstanding at December 31, 1995 and 1994.

Prices per share of outstanding rights at December 31, 1994  were
$5.94  to  $19.31.  During 1995 grants were awarded at prices  of
$10.69  to  $14.06, rights were exercised at $5.94 to $11.88  and
rights were forfeited at $10.25 to $19.31.  Rights outstanding at
December  31, 1995, are exercisable at prices ranging from  $5.94
to $19.31 per share.

The Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-
Based Compensation" (SFAS 123) in October, 1995.  Financial
statements presented for fiscal 1996 will measure the fair value
of stock-based compensation awarded to employees in 1995 and
thereafter.  SFAS 123 allows companies a choice between
continuing to account for stock-based awards using the intrinsic
value, as prescribed by Accounting Principles Board Opinion No.
25 (APB 25), or the fair value.  If the company chooses to
continue following APB 25, the pro forma effect the fair value
methodology would have had on net income and earnings per share
will be disclosed.  The company has not yet determined the
magnitude of the difference between the intrinsic value and fair
value approaches nor the method it will choose to account for
stock-based compensation.

The net change in the total valuation allowance for the years
ended December 31, 1995 and 1994 was an increase of $6.1 million
and a decrease of $1.3 million, respectively.

The company adopted Statement of Financial Accounting Standards
No. 109, "Accounting for Income Taxes," (SFAS 109), effective
January 1, 1993.  The statement requires that deferred income
taxes reflect the tax consequences on future years of differences
between the tax bases of assets and liabilities and their bases
for financial reporting purposes.  In addition, SFAS 109 requires
the recognition of future tax benefits, such as net operating
loss carryforwards (NOLs), to the extent that realization of such
benefits are more likely than not.  There was no cumulative
effect of this accounting change at the time of adoption.
                               -30-

The company had NOLs of approximately $192.1 million at December

businesses.  These NOLs expire as follows:

</TABLE>

Tax benefits of $4.9 million for investment tax credits expiring
in 1996 and later are also being carried forward.

Under the provisions of SFAS 109, NOLs represent temporary
differences that enter into the calculation of deferred tax
assets and liabilities.  At January 1, 1993, primarily as a
result of the NOLs, the company was in a net deferred tax asset
position under SFAS 109.  The full amount of the deferred tax
asset was offset by a valuation allowance due to uncertainties
associated with unresolved issues related to discontinued
operations.

In the fourth quarter of 1993, the company reduced its valuation
allowance resulting in a net deferred tax asset of $24.9 million.
Two factors contributed to the reduction in the valuation
allowance.  First was the
resolution of long-standing litigation between the company and
the City of Long Beach, California, regarding a waste-to-energy
plant the company built for the city and the ability to quantify,
relying upon advice of legal counsel, the potential financial
impact of the remaining uncertainties associated with previously
discontinued operations.  Second, the company was awarded a
contract to supply American Electric Power's Gavin plant with
450,000 tons of lime annually for 15 years commencing in 1995.
In addition,  the company had pending the renewal of existing
contracts which were finalized in 1994 and raised utility lime
sales backlog to $800 million.  With these contracts in place,
nearly 65 percent of the company's annual revenue was projected
to be generated from long-term contracts.  As a result, the
company believed that revenue and income from its lime subsidiary
could be reasonably projected over the life of its long-term
contracts.

The amount of the net deferred tax asset was not adjusted in
1995.  In assessing the valuation allowance, estimates were made
as to the potential financial impact on the company should
resolution of the remaining substantive uncertainty associated
with discontinued operations substantially exceed management's
estimates.  The uncertainty involves the Hastings, Nebraska,
environmental matter and is discussed more fully in Note 8,
Contingent Liabilities.  Management's position is to vigorously
pursue its claims against other PRPs and to contest the liability
for environmental clean-up.  In determining the appropriate
valuation allowance, however, management has used the upper limit
of the potential financial impact estimated for this matter.
Also, operating profits were lower than forecasted in 1995
primarily due to higher-than-expected expenses incurred during
start-up of the Black River expansion project.  The lower profit,
expenses related to discontinued operations and recognition for
tax purposes of fees and expenses totaling $9.5 million
associated with loans prepaid from funds received from the sale
of Dravo Basic Materials' assets created a tax loss and generated
additional NOLs.

Management believes that, with the resolution of the Black River
start-up problems, the company will generate sufficient future
taxable income to realize the entire deferred tax asset prior to
expiration of any NOLs and that the realization of a $24.9
million net deferred tax asset is more likely than not.  Income
projections for the contract lime business are based on
historical information adjusted for contract terms. In order to
fully realize the net deferred tax asset, the company will need
to generate future taxable income of approximately $73.2 million
prior to the expiration of the NOLs.

Historically, Dravo Lime's cumulative taxable earnings for the
past five years total $55.5 million.  There can be no assurance,
however, that the company will generate any earnings or any
specific level of continuing earnings.

Note 14:  Extraordinary Item

In conjunction with the sale of Dravo Basic Materials' assets,
existing loan agreements were substantially altered, including a
$35 million reduction in the amount available under a revolving
credit facility.  Also, while negotiating a financing agreement
with Prudential Power Funding for the Black River expansion, the
company purchased a call option that enabled it to prepay on May
17, 1995, without penalty, amounts outstanding under the
financing agreement.  Cash received from the Dravo Basic
Materials asset sale equaling the outstanding principal on the
Prudential Power Funding facility, interest through May 16, 1995
and an exit fee was placed in escrow.  With Prudential Power
Funding's consent, the entire amount borrowed was prepaid.  The
fees associated with these agreements were written off as
extraordinary items in 1994.

</TABLE>

The carrying amounts of notes receivable approximate fair value.
The fair value of notes payable and the Series D Preference Stock
is based upon the amount of future cash flows associated with
each instrument discounted using the company's estimated
borrowing rate for similar debt instruments of comparable
maturity.  The Preference Stock fair value also includes an
estimated factor to value the conversion feature.

Fair value estimates are made at a specific point in time, based
on relevant market information and information about the
financial instrument.  These estimates are subjective in nature
and involve uncertainties and matters of significant judgment and
therefore cannot be determined with precision.  Changes in
assumptions could significantly affect the estimates.

Independent Auditors' Report


The Board of Directors and Shareholders
Dravo Corporation:

We  have audited the accompanying consolidated balance sheets  of
Dravo  Corporation and subsidiaries as of December 31,  1995  and
1994,  and  the  related consolidated statements  of  operations,
retained  earnings and cash flows for each of the  years  in  the
three-year  period  ended December 31, 1995.  These  consolidated
financial  statements  are the responsibility  of  the  Company's
management.  Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

We  conducted  our  audits in accordance with generally  accepted
auditing  standards.  Those standards require that  we  plan  and
perform  the  audit to obtain reasonable assurance about  whether
the  financial statements are free of material misstatement.   An
audit  includes  examining, on a test basis, evidence  supporting
the  amounts  and  disclosures in the financial  statements.   An
audit also includes assessing the accounting principles used  and
significant  estimates made by management, as well as  evaluating
the  overall  financial statement presentation.  We believe  that
our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to
above  present  fairly, in all material respects,  the  financial
position of Dravo Corporation and subsidiaries as of December 31,
1995 and 1994, and the results of their operations and their cash
flows  for  each  of  the  years in the three-year  period  ended
December   31,  1995,  in  conformity  with  generally   accepted
accounting principles.

As  discussed  in  Notes 10 and 13 to the consolidated  financial
statements,  the  company adopted the method  of  accounting  for
postemployment  benefits  prescribed by  Statement  of  Financial
Accounting  Standards  No.  112  in  1994  and  the  methods   of
accounting  for postretirement benefits other than  pensions  and
income  taxes  prescribed by Statements of  Financial  Accounting
Standards Nos. 106 and 109, respectively, in 1993.
