                        DISCLOSURE STATEMENT AND NOTICE
              ----------------------------------------------------
 
     This   Disclosure  Statement  and  Notice   is  furnished  by  'Holderbank'
Financiere Glaris,  Ltd.,  a  publicly-held  Swiss  corporation  ('Holderbank'),
Holdernam  Inc.,  a  Delaware  corporation  ('Holdernam'),  and  Holcem  Inc., a
Delaware corporation  ('Holcem'),  in  connection with  the  taking  of  certain
corporate  action described below by  Holcem, as the holder  of more than 90% of
the common  stock  and  all the  preferred  stock  of Holnam  Inc.,  a  Delaware
corporation  (the  'Company'),  pursuant  to which  the  Company  will  become a
wholly-owned subsidiary of  Holdernam. This Disclosure  Statement and Notice  is
first being sent to stockholders of the Company on or about January 31, 1994.
 
     The  board  of directors  of Holcem,  together with  Holdernam as  the sole
stockholder of Holcem, approved on January 7, 1994 the merger (the 'Merger')  of
Holcem  with  and  into the  Company  pursuant  to Section  253  of  the General
Corporation Law of the State of Delaware  (the 'DGCL') with the result that  the
separate  corporate existence  of Holcem will  cease, Holdernam  will become the
owner of 100%  of the  outstanding equity of  the Company  and each  outstanding
share  of common stock,  par value $.01  per share (the  'Common Stock'), of the
Company (other  than any  shares owned  by Holcem  or held  by stockholders  who
perfect  their dissenters' appraisal rights) will be converted into the right to
receive $7.65 in  cash from Holdernam.  Such price is  slightly higher than  the
highest  price at which the  Common Stock has ever traded  on the New York Stock
Exchange since it was first listed thereon in March 1990. The Merger will become
effective at  the close  of  business on  the date  on  which a  certificate  of
ownership  and merger  (the 'Certificate of  Ownership and Merger')  is filed by
Holcem with the Secretary of  State of the State  of Delaware. Such filing  will
not  be earlier  than February 22,  1994, which is  more than 20  days after the
mailing of this Disclosure Statement and Notice.
 
     Holderbank, through  its  subsidiaries  and  affiliates,  ranks  among  the
largest  cement manufacturers and suppliers  in the world with  a presence in 30
countries. Holdernam is  a wholly-owned  subsidiary of Holderbank.  Holcem is  a
wholly-owned  subsidiary  of  Holdernam  recently  formed  for  the  purpose  of
effecting the Merger. Holdernam and Holcem are holding companies. Holcem is  the
owner   of  record   of  128,491,701   shares  of   Common  Stock,  representing
approximately 94.9%  of the  outstanding Common  Stock as  of January  6,  1994.
Holcem  is  also  the  owner  of  record  of  620,828  shares  of  7% Cumulative
Convertible Preferred Stock, par value $.10  per share (the 'Series A  Preferred
Stock'), of the Company which are convertible at a conversion price of $3.70 per
share into 8,381,178 shares of Common Stock.
 
     As  permitted and provided by Section 253  of the DGCL, the Merger has been
structured as a  short-form merger requiring  only the consent  of the board  of
directors  of Holcem as the holder of more  than 90% of the Common Stock and all
the Series  A Preferred  Stock of  the  Company concurred  in by  Holcem's  sole
stockholder,  Holdernam. The approval  of the Company's  stockholders other than
Holcem (the 'Public Stockholders')is  not required and  is not being  requested.
The Public Stockholders are not being asked for a proxy and are requested not to
send  a proxy. However, under Delaware law, the Public Stockholders are entitled
to be  treated  with  'entire  fairness'  in  the  Merger  and  also  will  have
dissenters'  appraisal rights in connection with  the Merger if they comply with
applicable requirements. See 'The Merger  -- Appraisal Rights.' This  Disclosure
Statement  also constitutes  notice by  the Company  to the  Public Stockholders
pursuant to Section 262(d)(2)  of the DGCL that  appraisal rights are  available
for any or all of the shares of Common Stock owned by them.
 
THIS  TRANSACTION  HAS  NOT  BEEN APPROVED  OR  DISAPPROVED BY  THE  SECURITIES
   AND   EXCHANGE   COMMISSION   NOR   HAS   THE   COMMISSION  PASSED   UPON
     THE  FAIRNESS  OR MERITS OF SUCH TRANSACTION  NOR  UPON  THE ACCURACY
        OR ADEQUACY  OF  THE  INFORMATION  CONTAINED  IN  THIS  DOCUMENT.
                 ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL.
 
     The date of this Disclosure Statement and Notice is January 31, 1994.

                                   THE MERGER
 
GENERAL
 
     The Certificate of Ownership and Merger provides that Holcem will be merged
with  and into the  Company. As a  result of the  Merger, the separate corporate
existence of Holcem will cease, Holdernam will  become the owner of 100% of  the
outstanding  equity of the  Company and the Public  Stockholders will possess no
further interest in, or rights as stockholders of, the Company, other than their
right to receive $7.65  per share of  Common Stock held by  them or to  exercise
dissenters'  appraisal rights if  they comply with  applicable requirements. See
'The Merger -- Appraisal Rights.'
 
     The description of the terms and conditions of the Merger included in  this
Disclosure Statement and Notice is qualified in its entirety by reference to the
Certificate of Ownership and Merger, a copy of which is attached hereto as Annex
A and incorporated herein by reference.
 
SPECIAL FACTORS
 
     For  a description  of certain special  factors concerning  the Merger, see
'The Merger  --  Background of  the  Merger,' 'The  Merger  -- Reasons  for  the
Merger,'   'The  Merger   --  Position  of   the  Boards   of  Directors,'  'The
Merger -- Opinion of Financial Advisor' and 'The Merger -- Potential  Detriments
and Adverse Effects of the Merger.'
 
EFFECTIVE TIME OF THE MERGER
 
     The Merger will become effective as of the close of business on the date on
which  the Certificate of  Ownership and Merger  is filed with  the Secretary of
State of the State of Delaware in accordance with applicable law. Such filing is
expected to occur on or about February 22, 1994. The time of such  effectiveness
is  referred to herein as the 'Effective  Time of the Merger.' Holcem may decide
not to proceed with the Merger at  any time, and for any reason sufficient  unto
itself,  before the filing of the Certificate  of Ownership and Merger. See 'The
Merger -- Amendment and Abandonment.'
 
PRICE TO BE PAID
 
     At the Effective Time of  the Merger, Holcem will  be merged with and  into
the  Company and each outstanding  share of Common Stock  (other than any shares
owned by Holcem  or held by  Public Stockholders who  perfect their  dissenters'
appraisal rights) will be converted into the right to receive $7.65 in cash from
Holdernam.  As of January 6, 1994, there were 135,356,186 shares of Common Stock
outstanding and  approximately  6,260 record  holders  of such  shares.  At  the
Effective  Time of the Merger, Holdernam will be required to pay an aggregate of
$52,513,310.25 for the 6,864,485 shares of Common Stock outstanding and held  by
the  Public  Stockholders if  no Public  Stockholders perfect  their dissenters'
appraisal rights.
 
     In addition, there are  outstanding under the  Company's Stock Option  Plan
employee  stock options to purchase 623,667 shares of Common Stock, all of which
are currently  exercisable and  will  terminate at  the  Effective Time  of  the
Merger.  See 'The Merger -- Stock Options  and Benefit Plans.' In order to spare
the holders of these stock options the burden of exercising them, Holdernam  has
agreed  to  cause  the  Company  to  make a  cash  payment  to  such  holders of
unexercised options  after the  Merger  in an  amount  equal to  the  difference
between  the per  share exercise price  of their options and the highest closing
sales price for  the Common  Stock on  the New  York Stock  Exchange, Inc.  (the
'NYSE')  from January 6, 1994 through the  Effective Time of the Merger. If such
highest NYSE closing  sales price is  $7.75 and all  these stock options  remain
unexercised  at the Effective Time of the  Merger, Holdernam will be required to
pay an  aggregate  of $624,833.50  to  such holders.  If  any such  options  are
exercised,  the shares issued upon such exercise will be converted in the Merger
into the right to receive $7.65 per share. See 'The Merger -- Stock Options  and
Benefit Plans.'
 
     Holcem  will cease to  exist at the  Effective Time of  the Merger and will
receive no cash  for any of  its shares of  Common Stock or  Series A  Preferred
Stock.  Holdernam will be issued  shares of common stock  and preferred stock of
the  Company,  as  the   surviving  corporation  in   the  Merger,  which   will
 
                                       3
 
<PAGE>
constitute  100%  of the  outstanding common  stock and  preferred stock  of the
Company after the Merger. See 'The  Merger -- The Company's Post-Merger  Capital
Stock.'
 
REGULATORY MATTERS
 
     There are no federal or state regulatory approvals or consents that must be
obtained in connection with the Merger.

it  is  one of  the largest  cement companies  in  the world  in terms  of rated
capacity with  total  worldwide  rated  capacity as  of  December  31,  1993  of
approximately   62  million  short  tons   per  year.  Holderbank's  shares  are
publicly-held and traded on the Zurich, Basle and Geneva stock exchanges and  in
London  on the SEAQ  International. Holderbank first  entered the North American
cement industry in Canada in 1951 and is today, on a combined basis, one of  the
largest  cement companies  in the  United States  and Canada  in terms  of rated
capacity. Holderbank's investments in the United States and Canada account for a
significant portion of its worldwide revenue and earnings.
 
     Holderbank entered the cement industry in North America by investing in St.
Lawrence Cement Inc., a corporation incorporated on March 13, 1951 under Part  I
of  the  Companies  Act (Quebec)  ('St.  Lawrence'). St.  Lawrence  is primarily
involved  in  the  manufacture  and  distribution  of  cement  for  use  by  the
construction  industry. St. Lawrence's cement operations are supplemented by its
involvement in certain related industries  such as ready-mix concrete,  concrete
products,  aggregates (crushed  stone, sand  and gravel),  road construction and
certain other  civil  engineering  work.  Directly  or  indirectly  through  its
subsidiaries,  St. Lawrence does  business in Eastern Canada  and in portions of
the Northeast  and Middle  Atlantic  regions of  the United  States.  Holderbank
currently  owns through  the Company 10,498,748  Class A  subordinate shares and
15,252,848 Class B shares representing an approximately 59% equity interest  in,
and  approximately 77% of the voting rights of, St. Lawrence. The balance of the
Class A subordinate  shares are  publicly-held and  traded on  the Montreal  and
Toronto stock exchanges.
 
     Holderbank  later invested in Dundee Cement Company, which was incorporated
on May 15, 1957 under the laws  of the State of Delaware ('Dundee'). Dundee  was
involved  in the manufacture  and distribution of a  variety of Portland cements
used in the construction  industry. Dundee operated in  portions of the  Midwest
and  Southeast United States.  The Company was  incorporated on May  8, 1981 and
used as a holding company. Dundee was merged with and into the Company on  March
21, 1990.
 
     In  order  to expand  and geographically  diversify  its holdings  in North
America, Holderbank invested  in Ideal Basic  Industries, Inc., a  publicly-held
manufacturer of Portland cement incorporated in 1924 under the laws of the State
of  Colorado ('Ideal'). In connection with a major debt and equity restructuring
of Ideal that took place in December of 1986, Holdernam acquired, for the sum of
$110,000,000,  from  the   bank  and   insurance  company   lenders  to   Ideal,
approximately  118.7  million  shares  of  common  stock  of  Ideal  (the 'Ideal
Shares'), representing approximately 68.3%  of the common  shares of Ideal  then
outstanding.  The balance of the common  shares were publicly-held and traded on
the NYSE. At the time of Holdernam's acquisition of the Ideal Shares, Holderbank
announced that, while respecting  Ideal's autonomy, to  enable Ideal to  benefit
from  combining with a  financially healthy and  more geographically diversified
group, it would consider the feasibility of a
 
                                       4
 
<PAGE>
future business combination  of Ideal with  all or parts  of Holderbank's  other
North American cement operations.
 
     To these ends, on March 8, 1990, Ideal was merged with and into the Company
(the  'Ideal  Merger')  following  the  approval  of  the  terms  of  the merger
transaction by a majority of Ideal's board of directors after its receipt of the
report and recommendation  of a  special committee  of Ideal  directors and  the
favorable  vote of the  stockholders of the  Company and Ideal.  Pursuant to the
merger agreement entered into in connection  with the Ideal Merger, the  Company
agreed  that for three years following the  Ideal Merger it would not enter into
any transaction which would result in the  Common Stock being held of record  by
fewer  than  300 holders  without the  approval of  at least  a majority  of the
Company's unaffiliated directors. As a result of the Ideal Merger, the  separate
corporate  existence of  Ideal ceased.  Upon consummation  of the  Ideal Merger,
Holderbank owned  indirectly  approximately  87.2%  of  the  Common  Stock  then
outstanding,  while the former public  stockholders of Ideal owned approximately
12.8% of the Common Stock then outstanding. In order to make Dundee part of  the
integrated  North American cement business of Holderbank, Dundee was merged with
and into the Company  (the 'Dundee Merger') following  the Ideal Merger and  the
separate  corporate existence of  Dundee ceased. Prior to  the Ideal Merger, the
Company had become  the holder  of Holderbank's stockholdings  in St.  Lawrence.
Therefore,  following the  Ideal Merger  and the Dundee  Merger in  1990, all of
Holderbank's cement operations in the United States and Canada were consolidated
in the Company whose common shares were traded on the NYSE.
 
     To provide  additional  equity needed  by  the Company,  in  October  1990,
Holdernam  purchased  from the  Company  22,222,223 originally-issued  shares of
Common Stock  for an  aggregate purchase  price of  $100,000,000 (or  $4.50  per
share).  The  terms  of  the  transaction were  established  in  August  1990 in
negotiations between the management of  the Company and Holderbank, reviewed  by
the  audit committee of  and approved by  the Company's Board  of Directors. The
closing price of the Common Stock on the  NYSE on the day of the agreement  with
Holderbank  was $4.25 per  share and the  average trading price  for the 60 days
prior to  the agreement  was $4.38  per share.  As a  result of  such  purchase,
Holderbank  owned  indirectly  approximately  89.3%  of  the  Common  Stock then
outstanding.
 
     In connection with the settlement of certain litigation arising out of  the
Ideal  Merger, on  December 31,  1991, Holdernam  purchased 8,181,019  shares of
Common Stock from Philip  F. Anschutz and The  Anschutz Corporation for a  total
consideration  of $34,769,330.75  or $4.25 per  share. The closing  price of the
Common Stock on the NYSE on such date was $4.625 per share. As a result of  such
purchase,  Holderbank owned indirectly  approximately 95.3% of  the Common Stock
then outstanding.
 
     On March 30, 1992, the Company  entered into a Subordinated Loan  Agreement
with  Holdernam pursuant to which  Holdernam lent $50,000,000 (the 'Subordinated
Loan') to the Company. Interest accrues  on the outstanding principal amount  of
the  Subordinated Loan at a  rate per annum equal to  the LIBO Rate (as defined)
plus 3%  in  those calendar  years  in which  the  Consolidated Net  Income  (as
defined)  of the Company equals or  exceeds $5,000,000. Because Consolidated Net
Income of the  Company did not  equal or exceed  $5,000,000 in 1992  and is  not
expected  to do so in 1993, no interest  has accrued or is expected to accrue on
the outstanding principal amount of the Subordinated Loan for such years.
 
     On January 1, 1993, the Company  entered into a revolving credit note  with
Holderfin  B.V.,  an affiliate  of Holderbank  ('Holderfin'), pursuant  to which
Holderfin lent $30,000,000  (the 'Revolving  Credit Loan') to  the Company.  The
Revolving  Credit Loan bears interest at LIBOR plus .75% and matures on December
31, 1996 or is payable on demand with 367 calendar days' prior notice.  Accruals
on the Revolving Credit Loan during 1993 were approximately $1,123,000.
 
     During  1993 and 1992, Holderbank provided financial support to the Company
in the form  of comfort  letters for certain  bank debt  and other  obligations.
Holderbank  received fees  from the  Company for  this financial  support in the
amount  of  approximately   $1,123,000  and   $2,345,000  in   1993  and   1992,
respectively.  In  view of  the Company's  current financial  circumstances, the
Company's ongoing ability to borrow from  its sources of financing is  dependent
on Holderbank's continuance of such support and the lenders' acceptance of these
comfort letters.

     On  May 18, 1993, the  Company issued 600,000 shares  of Series A Preferred
Stock to Holdernam  for $30,000,000 in  connection with the  acquisition on  the
same  date by a  Delaware limited partnership  consisting of entities affiliated
with the Company and  Trammel Crow of a  cement manufacturing plant, two  cement
distribution  terminals,  a  related  limestone  quarry  operation  and  working
capital. Each share  of the Series  A Preferred Stock  is convertible into  13.5
shares  of Common Stock representing a conversion  price of $3.70 per share. The
closing price of the  Common Stock on the  NYSE on the date  of issuance of  the
Series  A Preferred  Stock was  $3.00 per  share. The  Series A  Preferred Stock
entitles the holder thereof to receive annual preferential cumulative  dividends
of  $3.50 per share, payable in quarterly  installments on each February 15, May
15, August  15  and November  15,  beginning August  15,  1993. The  Company  is
permitted  to  pay these  dividends  by issuing  additional  shares of  Series A
Preferred Stock in an  amount equivalent to the  dividends otherwise payable  in
cash  based on the liquidation  value of $50 per  share. Pursuant to this right,
the Company issued 10,150 shares and  10,678 shares of Series A Preferred  Stock
on August 15 and November 15, 1993, respectively; Holcem currently holds 620,828
shares  of Series A Preferred Stock  convertible into 8,381,178 shares of Common
Stock. If such conversion should occur,  Holcem would hold approximately 95%  of
the  outstanding Common Stock.  If the Merger  should not occur,  the Company is
expected to  issue  on February  15,  1994 another  10,864  shares of  Series  A
Preferred Stock convertible into an additional 146,664 shares of Common Stock.
 
     Activities  Preceding the Merger. The management of Holderbank from time to
time has reviewed  the advantages  and disadvantages of  alternative methods  of
structuring  and financing its  operations in North America.  In this regard, in
February of 1992, a representative  of Holderbank requested that the  management
of  the Company explore and report on the advantages and disadvantages of taking
the Company private at that time. In response to that request, management of the
Company  forwarded  to  Holderbank  a  summary  of  the  advantages   (including
eliminating  the  'fishbowl' management  environment as  well as  the additional
costs and  management  time  for auditing  services,  legal  services,  exchange
listing fees, printing services, mailing costs, directors fees and directors and
officers  liability insurance premiums  for a public  company) and disadvantages
(including funding of  the costs of  such a transaction)  of taking the  Company
private  at that time. The advantages and disadvantages contained in the summary
were discussed  by  representatives of  Holderbank  and the  management  of  the
Company  during a 30-minute  tele-conference in March  of 1992. Participating on
behalf of the Company were its  then president and chief executive officer,  its
chief  financial officer  and its  general counsel.  Participating on  behalf of
Holderbank were various  members of  its executive committee.  No conclusion  or
action  resulted from these  discussions. In September  1993, following a recent
successful public offering of stock by a competitor and at Holderbank's  request
for  a report, the  Company sought the  views of Goldman,  Sachs & Co. ('Goldman
Sachs'), an investment  banking firm of  international reputation retained  from
time  to  time by  the  Company, as  to the  feasibility  of effecting  a public
offering by the Company of its Common Stock in the United States.
 
     On October 11,  1993, Goldman  Sachs presented its  initial view,  together
with  written  materials  dated  that  date  (the  'Goldman  Sachs  Presentation
Materials'), which  preliminarily indicated  that a  public offering  of  Common
Stock in the United States might be feasible at the current trading price of the
Common  Stock on  the NYSE or  at a  slight reduction therefrom  (i.e. $5.00 per
share or less),  with final pricing  to be determined  at the time  of any  such
offering  and dependent on the size of  the offering and other relevant factors.
Goldman Sachs'  preliminary report  considered, first,  the Company's  potential
objectives  in an  equity offering  -- to  achieve a  new source  of funding for
attractive capital projects or potential acquisitions, to reduce leverage in the
capital structure of the Company, to  promote liquidity of the Common Stock,  to
broaden  the  ownership base  and  to create  a  research following.  The report
reviewed the market for equity offerings which it viewed as relatively favorable
for any such offering, reviewed the Company's capitalization and the history  of
the  Common Stock  prices and concluded  with a  listing of various  steps to be
followed to maximize  chances for a  successful public offering  at or  slightly
below  the then $5.00  market price. It  should be noted  that the Goldman Sachs
presentation was  preliminary and  was rendered  in the  context of  a  possible
transaction   different  from   the  Merger.  Goldman   Sachs  provided  further
preliminary advice and information to the  management of the Company in  October
and   November   1993   to   the   effect  that   using   the   proceeds   of  a
 
                                       6
 
<PAGE>
public offering of Common Stock  by the Company to  buy out the public  minority
stockholders  of St. Lawrence would be advantageous to the Company under certain
circumstances.
 
     Neither Holderbank, Holdernam nor  Holcem has currently  or has had  within
the  past two years  or hereafter contemplates  having any material relationship
with Goldman  Sachs  or any  of  its  affiliates. Goldman  Sachs  has,  however,
provided investment banking services to the Company from time to time within the
past  two years  for which it  has received  customary fees. The  Company has no
agreement to  compensate Goldman  Sachs  for its  work  in connection  with  the
Goldman   Sachs  Presentation  Materials  or  its  subsequent  advice.  However,
Holderbank's understanding is that it is  the Company's belief that, were it  to
undertake  a public  offering of  its Common  Stock, the  expectation of Goldman
Sachs  was  that  such  investment  banking  firm  would  serve  as  a  managing
underwriter of the offering and would receive compensation in that capacity.
 
     At  the request of Holderbank, on November 15, 1993, Merrill Lynch, Pierce,
Fenner &  Smith  Incorporated  ('Merrill  Lynch') made  a  presentation  to  the
management  of Holderbank (the 'November 15 Presentation') together with written
presentation materials (the 'November 15 Presentation Materials'). Specifically,
Merrill Lynch was asked  to analyze preliminarily (i)  a public offering of  the
Common  Stock (the 'Public Offering'), (ii) alternatives available to Holderbank
with respect  to the  Public Stockholders  and (iii)  alternatives available  to
Holderbank  with respect  to the  Company's interest  in St.  Lawrence (the 'St.
Lawrence Interest') in light of Holderbank's long-term objectives of  maximizing
the  attractiveness of Holderbank's stock  to investors, maximizing Holderbank's
financial efficiency (i.e., minimizing the  cost of funds and optimizing  access
to  cash  flows)  and optimizing  flexibility  regarding the  operations  of its
subsidiaries. Merrill  Lynch  based  its  analysis  on  public  information  and
information  provided by senior management of Holderbank from different sources,
including the Company's 1993  budget and 1994/5 forecast  and the Goldman  Sachs
Presentation  Materials. In addition,  Merrill Lynch, was  provided with certain
projections of the  Company and St.  Lawrence by members  of Holderbank and  the
Company's  management. Merrill  Lynch presented its  analysis in  three parts: a
'subsidiary  analysis'  of  St.  Lawrence  and  the  Company;  an  'alternatives
analysis'  for Holderbank; and  a 'competitor analysis'  with respect to Lafarge
Coppee.
 
     Subsidiary Analysis. Merrill Lynch performed a preliminary analysis of  the
historical and projected earnings of both St. Lawrence and the Company excluding
St.  Lawrence (the  'Holnam Operations') from  1992 through  1997, calculating a
compounded average earnings growth  from 1995 to 1997  of approximately 59%  for
St.  Lawrence  and  approximately  20% for  Holnam  Operations.  Based  on these
projected earnings, Merrill Lynch calculated a projected market value of the St.
Lawrence  Interest  of   approximately  $300  million   based  on  a   projected
price/earnings  multiple (a 'P/E Multiple') of 19.5x in 1994, approximately $462
million based on  a projected P/E  multiple of 15.0x  in 1995 and  approximately
$500  million based on a projected P/E multiple of 13.0x in 1996 and a projected
market value of the Company of  approximately $920 million based on a  projected
P/E multiple of 15.0x in 1994, approximately $1,292 million based on a projected
P/E  multiple  of 14.0x  in 1995  and  approximately $1,455  million based  on a
projected P/E multiple of 13.0x in  1996. In addition, Merrill Lynch  calculated
free cash flows for St. Lawrence as increasing from approximately $10 million in
1994 to approximately $63 million in 1997 and for the Company as increasing from
approximately $47 million in 1994 to approximately $316 million in 1997.
 
     Holderbank Alternatives. Merrill Lynch compared the internal rate of return
for  Holderbank  ('IRR') based  on  five strategic  alternatives.  Alternative I
assumed that  Holderbank held  a 79.8%  stake in  the Company  after the  Public
Offering  (as  $5.00 per  share)  and maintained  status  quo ownership  for St.
Lawrence and resulted in an IRR  of approximately 20.0%. Alternative II  assumed
that  Holderbank held a 68%  stake in the Company  after the Public Offering (at
$5.00 per share) and had completed a  100% buy out of St. Lawrence and  resulted
in  an  IRR of  approximately 17.78%.  Alternative  III assumed  that Holderbank
maintained status  quo ownership  for  both the  Company  and St.  Lawrence  and
resulted  in  an  IRR  of  approximately  25.8%.  Alternative  IV  assumed  that
Holderbank held a 100% stake in both  the Company due to a going private  merger
(at  $6.90 per share based on a premium of 20% over market price on November 12,
1993) and St. Lawrence due to a cash buy out (at Cdn. $12.19 per share based  on
a  premium of 25% over the market price on November 12, 1993) and resulted in an
IRR of approximately 30.4%. Alternative V assumed 100% ownership of the  Company
due to a going
 
                                       7
 
<PAGE>
private  merger and status quo ownership for St. Lawrence and resulted in an IRR
of approximately 27.5%.
 
     Merrill Lynch also calculated  the cumulative free  cash flow projected  by
management  of the Company and St. Lawrence from 1994 through 1997 and free cash
flow beyond  1997  based  on  the five  strategic  alternatives.  Merrill  Lynch
calculated that Holderbank would receive (i) approximately $71 million in public
offering  proceeds plus  dividends from  the Company  ('Holnam Dividends') under
Alternatives I and II through 1997 and Holnam Dividends beyond 1997; (ii) Holnam
Dividends throughout all periods under Alternative III; (iii) approximately $290
million (approximately  $79 million  after payment  of acquisition  debt)  under
Alternative  IV through 1997 and approximately $119 million annually thereafter;
and (iv) approximately $268 million (approximately $221 million after payment of
acquisition debt) plus dividends from  St. Lawrence under Alternative V  through
1997 and approximately $90 million annually thereafter.
 
     Based   on  this  analysis,  Merrill  Lynch  concluded  preliminarily  that
Holderbank's  long-term  objectives  would  be  most  effectively  addressed  by
Alternative  IV, the elimination of public holdings  of both the Company and St.
Lawrence by a short-form cash merger and buy out for cash, respectively. It  was
Merrill Lynch's belief that full ownership of the Company and St. Lawrence would
enhance Holderbank's share valuation in the European and other financial markets
in  which its shares trade by focusing  investors on Holderbank as a core global
cement investment  and  confirming  Holderbank's  industrial  operating-company,
rather than holding-company, status.
 
     Competitor  Analysis. Merrill Lynch  presented a preliminary  case study of
LaFarge Coppee and the public offering of its subsidiary, LaFarge Corp.  Merrill
Lynch  analyzed  share price  performance  and volume  from  August 24,  1993 to
November 5,  1993  among LaFarge  Coppee,  Lafarge Corporation  and  Holderbank,
noting  that the Lafarge  Corporation roadshow coincided with  a drop in Lafarge
Coppee share price and that Holderbank's relative volume was consistently  above
Lafarge Coppee's during the period. Merrill Lynch concluded preliminarily on the
basis  of the Lafarge Coppee case study  that a public offering of the Company's
common stock could be well received by the equity markets but could also  weaken
the  perception of Holderbank as an operating company and otherwise might not be
beneficial to its share performance.
 
     Merrill Lynch  also analyzed  relative  valuations between  Holderbank  and
LaFarge  Coppee. In comparison  to LaFarge Coppee,  Holderbank's market value to
estimated 1994 earnings was  negative 15%, market value  to estimated 1994  cash
flow  was negative 27%,  market capitalization to  current capacity was negative
37% and market capitalization to the latest fiscal year output was negative 36%.
Merrill  Lynch  stated  that  reasons  for  this  relative  underperformance  of
Holderbank  could  include  Holderbank's  lack of  interim  reporting,  its less
developed investor program and less diversified shareholder base and the absence
of a  control premium  for  Holderbank shares.  Merrill Lynch  recommended  that
Holderbank  increase its efforts  to communicate with  its investors, expand its
shareholder base and optimize control over its subsidiary operations.
 
     The November 15  Presentation and  the November  15 Presentation  Materials
were  not intended  to, and  do not,  provide for  a valuation  of St. Lawrence,
Holnam Operations, the  Company, any of  their assets or  the Holnam Shares.  In
connection  with the investigation of the  Company and St. Lawrence conducted by
Merrill Lynch as part of its  valuation analysis discussed below under  'Opinion
of  Financial Advisor,'  Merrill Lynch  received substantially  more information
with respect to the Company and  St. Lawrence, and substantially more access  to
information  and personnel at the Company and  St. Lawrence, than it received in
connection with the November 15 Presentation. Holdernam paid Merrill Lynch a fee
of $125,000 in connection with the November 15 Presentation.
 
     Following the November 15 Presentation, Holderbank decided against a  going
private  transaction  with  respect  to  St.  Lawrence  but  to  pursue  such  a
transaction with respect to the Company. By letter agreement dated December  10,
1993, Holdernam retained Merrill Lynch to act as its exclusive financial advisor
in  connection with the possible acquisition of all of the outstanding shares of
Common Stock not owned by Holdernam or its affiliates. Subsequent to such  date,
officers  of Holderbank, Holdernam, the Company  and St. Lawrence engaged in due
diligence meetings with representatives of Merrill Lynch.
 
                                       8
 
<PAGE>
     During the  course of  these due  diligence discussions  management of  the
Company and Merrill Lynch jointly prepared projections of the future performance
of  the  Holnam Operations,  and management  of St.  Lawrence and  Merrill Lynch
jointly prepared projections of the future performance of St. Lawrence, in  each
case  for the  years 1994  through 2002,  which were  approved by  management of
Holdernam  (the   'Holnam  Operations   Projections'  and   the  'St.   Lawrence
Projections,'  respectively). Neither  the Company nor  St. Lawrence customarily
prepares such long-term projections. The  Holnam Operations Projections and  the
St.  Lawrence  Projections  and  the material  assumptions  related  thereto are
attached hereto as Annex B and Annex C, respectively.
 
     The projections were  intended for the  uses discussed below  and were  not
prepared  with  a  view  toward  compliance  with  published  guidelines  of the
Commission or the American Institute  of Certified Public Accountants  regarding
projections  and forecasts or generally  accepted accounting principles. Because
of the  inherent  uncertainty of  projections  and forecasts  for  such  lengthy
periods,  no assurances can be given  that such projections accurately determine
current values or future  performance, which may be  significantly more or  less
favorable than as set forth therein.
 
     Pursuant  to the  engagement agreement, on  January 7,  1994, Merrill Lynch
delivered an opinion, subsequently confirmed in a written opinion dated  January
7,  1994, to the board of directors of  each of Holcem and Holdernam, and to the
special committee of the board of directors of Holderbank, that on the basis and
subject to the matters set  forth therein, as of the  date of such opinion,  the
proposed  cash consideration  to be received  by the Public  Stockholders in the
Merger is fair to  such stockholders from  a financial point  of view. See  'The
Merger -- Opinion of Financial Advisor.' Merrill Lynch further advised the board
of  directors of each of  Holcem and Holdernam and  the special committee of the
board of directors of  Holderbank that, in accordance  with its assignment,  its
opinion was directed to the issue of fairness to the Public Stockholders and not
to  fairness to the  stockholders of Holderbank. Merrill  Lynch also reviewed at
length with the members of  the boards and the  special committee the bases  for
its  opinion. The  members of  the boards  and the  special committee considered
Merrill Lynch's  presentation in  support of  its opinion,  asked questions  and
satisfied  themselves  that  Merrill  Lynch had  fully  considered  all relevant
factors and  performed its  task with  diligence and  care appropriate  in  this
circumstance.  The members of the boards and the special committee noted Merrill
Lynch's affirmative response when asked whether it was prepared to opine that  a
price  of $7.50 per share is  fair from a financial point  of view to the Public
Stockholders and further noted that $7.50 is above, or in the upper portion  of,
each  equity reference  range derived  by Merrill  Lynch. In  fact, none  of the
various analyses performed by Merrill Lynch produced a mean valuation in  excess
of  the $7.65 per share  of Common Stock which the  board of directors of Holcem
determined to pay to  the Public Stockholders  in the Merger.  In light of  such
opinion   and  presentation  and  on  advice   from  their  counsel  that  their
responsibility was not  to negotiate  the best  or most  advantageous price  for
Holcem,  Holdernam or  Holderbank but  rather solely  to ensure  that the Public
Stockholders are treated with entire fairness, on January 7, 1994, the board  of
directors of each of Holcem and Holdernam and the special committee of the board
of   directors   of   Holderbank,   for  the   reasons   described   under  'The
Merger -- Position  of the  Board of Directors,'  concluded that  the Merger  is
entirely fair to the Public Stockholders.
 
     In  order to effect the Merger,  Holdernam transferred the Common Stock and
Series  A  Preferred  Stock  owned  by  it  to  its  newly-formed   wholly-owned
subsidiary, Holcem, on January 7, 1994, in exchange for stock of Holcem. Neither
Holderbank,  Holdernam nor Holcem nor any of the directors or executive officers
of any of them has engaged in  any other transaction involving the Common  Stock
since November 7, 1993.
 
REASONS FOR THE MERGER
 
     After  considering various  alternatives to  structuring and  financing its
operations in North America as discussed  above under 'The Merger --  Background
of  the Merger,' Holderbank decided that the most advisable course of action was
to merge out the Public Stockholders for cash. Holderbank seeks to merge out the
Public Stockholders primarily for the following reasons:
 
          (i) The Merger will  secure for Holderbank the  freedom to manage  the
     business  of the Company  without the inherent  complexities of operating a
     U.S. public company.
 
                                       9
 
<PAGE>
          (ii) The  Merger will  avoid the  significant costs  of maintaining  a
     publicly-traded U.S. company, particularly with its potential for expensive
     and  time-consuming  litigation.  The  management of  the  Company  and the
     management of  Holdernam  have  estimated  that  such  savings  may  exceed
     $500,000 per year apart from any litigation.
 
          (iii)  The Merger will allow Holderbank to fully control the cash flow
     of the Company so that, if and when opportune, it might reinvest such funds
     in business opportunities elsewhere.
 
          (iv) The Merger will confirm Holderbank's industrial operating-company
     status in the European and other financial markets.
 
     The Merger was structured as a  short-form merger because this approach  is
expressly  permitted and provided by Delaware law  and is the most efficient way
to achieve the intended  purposes. The board of  directors of Holcem  considered
the  possibility of making the Merger subject to approval by a special committee
of independent  directors of  the  Company and/or  by the  vote  of at  least  a
majority  of the  shares of  Common Stock held  by the  Public Stockholders. The
board of directors of Holcem decided against using such procedures for a  number
of  reasons,  principally  because  the DGCL  specifically  makes  available the
short-form merger described in this Disclosure Statement and Notice and  because
the  board of directors felt confident that it could, with the advice of Merrill
Lynch, arrive at a price per share that is fair to the Public Stockholders.  The
Merger  was undertaken  at this time  because, among  other reasons, contractual
restrictions on such action  arising in relation to  the Ideal Merger lapsed  in
March  1993,  because  equity offerings  completed  in 1993  by  Holderbank have
enhanced its ability to undertake the transaction in 1994 and because reviews by
the management of the  Company and the management  of Holderbank in October  and
November  of  1993 and  in  February and  March of  1992  of the  advantages and
disadvantages of  various alternative  courses  of action  with respect  to  the
structure  and financing of operations in the United States discussed above have
led to  decisions  being  made  at  this  time.  More  specifically,  Holderbank
determined  that it does not wish to  increase public minority investment in the
Company because  it does  not  believe such  action would  support  Holderbank's
long-term  objectives of maximizing the  attractiveness of Holderbank's stock to
investors,  maximizing   Holderbank's   financial  efficiency   and   optimizing
flexibility  regarding the operations  of its subsidiaries.  Having reached this
conclusion,  Holderbank  further  determined  that  there  were  no  significant
advantages  and several disadvantages  (namely, inherent operating complexities,
significant costs  and  the  potential  for litigation)  to  having  the  Public
Stockholders as continuing minority investors in the Company. This determination
in  turn led to Holderbank's decision to effect  a cash out merger of the Public
Stockholders.
 
POSITION OF THE BOARDS OF DIRECTORS
 
     The  boards  of  directors  of  Holderbank  (acting  through  its   special
committee),  Holdernam and Holcem (collectively,  the 'Boards') believe that the
Merger is fair to  the Public Stockholders. The  material factors on which  this
belief  is based and which support the conclusion that the Merger is fair to the
Public Stockholders include the following:
 
          (i) Historical  results of  operations of  the Company  over the  last
     several   years  with  particular  note  of  significant  operating  losses
     generated by the Company since the Company became a public company in 1990.
 
          (ii) The  fact that  the industry  in which  the Company  operates  is
     cyclical  and there is  some evidence that  the industry is  currently in a
     period of growth in  demand, with scant new  capacity recently added or  in
     prospect, and that in certain markets prices for the Company's products may
     increase.
 
          (iii)  The  assets,  liabilities,  financial  condition,  business and
     operations of the Company  and the Boards'  judgment concerning the  future
     prospects for the Company's business in light of the Company's competition,
     forecasts  of sales  and costs,  and projected  levels of  required capital
     investment,  corporate  overhead,  litigation  expenses  and  environmental
     expenses.  A  long-term  concern  with  potential  adverse  effect  on  the
     Company's profitability is  that while approximately  31% of United  States
     cement manufacturing capacity employs the less efficient wet process, about
     60% of the Company's capacity is wet process. In general, the Company's wet
     process plants
 
                                       10
 
<PAGE>
     currently  compete in markets supplied  by other manufacturers with similar
     cost structures. However, if these competitors upgrade their plants  (e.g.,
     by   converting  from  wet  to  dry  process),  the  Company  could  become
     competitively disadvantaged  in some  markets unless  it makes  significant
     additional  investments  to  effect similar  conversions.  If  cement price
     levels (after adjusting  for inflation)  are not adequate  to support  such
     investment,  the Company could experience deterioration in profitability or
     losses. Over the almost thirty year period from 1960 to 1989, cement  price
     levels after adjustment for inflation trended downward.
 
          (iv)  The  opinion,  dated  January  7,  1994,  of  Merrill  Lynch, as
     financial advisor  to Holdernam,  that, on  the basis  and subject  to  the
     matters  set forth therein,  as of the  date of such  opinion, the proposed
     $7.65 per share of Common Stock  to be received by the Public  Stockholders
     in  the Merger is fair from a financial point of view to such stockholders;
     and the considerations and analyses reflected therein and presented to  the
     Boards  by Merrill Lynch. The Boards adopted Merrill Lynch's conclusion and
     analyses as  their own,  but emphasized  additional factors,  as set  forth
     herein, further to support their judgment.
 
          (v)  The relationship between the  price to be paid  in the Merger and
     the trading history  of the Common  Stock, including the  level of  trading
     activity  in the Common Stock and the fact that the price to be paid in the
     Merger represents a premium of  approximately 13.3% over the closing  sales
     price  of $6.75 on the NYSE on January 6, 1994, the last trading day before
     the public announcement of the Merger.
 
     In view  of the  variety of  factors considered  in connection  with  their
evaluation  of the Merger,  the Boards did  not find it  practicable to, and did
not, quantify or otherwise  attempt to assign relative  weights to the  specific
factors  they  considered. However,  the Boards  gave  particular weight  to the
factors discussed in (iii) and the analyses and opinion described in (iv) above.
The Boards also considered  that the Public Stockholders  may elect to have  the
value  of  their shares  appraised  by the  Court of  Chancery  of the  State of
Delaware in accordance with Section 262 of the DGCL.
 
     Because the Merger is structured as a short-form merger requiring only  the
consent  of  the board  of directors  of  Holcem concurred  in by  Holcem's sole
stockholder, Holdernam, the Merger was not submitted to a vote of the  directors
of  the Company and the  approval of a majority of  the directors of the Company
who are not employees of the Company was not sought.
 
     As permitted by Section 253 of the DGCL, the Merger has been structured  as
a  short-form merger  requiring only  the consent of  the board  of directors of
Holcem as the holder of more than 90%  of the Common Stock and all the Series  A
Preferred  Stock  of  the Company  concurred  in by  Holcem's  sole stockholder,
Holdernam. The Boards  decided not to  condition the Merger  on the  affirmative
vote  of at least  a majority of the  shares of Common Stock  held by the Public
Stockholders or the approval by a special committee of independent directors  of
the  Company and not to have the  independent directors of the Company retain an
unaffiliated representative to act solely  on behalf of the Public  Stockholders
for  purposes  of negotiating  the terms  of  the Merger  or preparing  a report
concerning the  fairness of  the  Merger to  the Public  Stockholders.  However,
Holdernam  did retain Merrill Lynch as  an unaffiliated representative to render
an opinion whether, from a financial point of view, the cash consideration to be
received by the Public Stockholders in the Merger is fair solely with respect to
such stockholders  and  without  considering fairness  to  the  stockholders  of
Holderbank.   The  Boards  understood  that,  under  Delaware  law,  the  Public
Stockholders are entitled to 'entire fairness'  with respect to the Merger.  The
board of directors of Holcem felt confident that it could, with such advice from
Merrill  Lynch,  arrive  at  a  price  per  share that  is  fair to  such Public
Stockholders. The Boards also  noted that the Public  Stockholders may elect  to
have  the value of their shares appraised by  the Court of Chancery of the State
of Delaware in accordance  with Section 262  of the DGCL.  On advice from  their
counsel  that  their responsibility  was  not to  negotiate  the best  price for
Holcem, Holdernam or  Holderbank but instead  solely to ensure  that the  Public
Stockholders  are treated with entire fairness,  on January 7, 1994, the Boards,
for the  reasons described  above,  concluded that  the Merger  satisfies  their
obligation of entire fairness to the Public Stockholders.
 
     To   the  knowledge  of  Holderbank,  Holdernam  and  Holcem  after  making
reasonable inquiry, no executive officer or director of the Company, other  than
those  who are directors of  Holderbank, Holdernam or Holcem  (all of whom voted
for   the    Merger),    has   made    a    recommendation   in    support    of
 
                                       11
 
<PAGE>
or  opposed  to the  Merger. Each  outstanding  share of  Common Stock  owned by
executive officers and directors of the Company will also be converted into  the
right  to  receive $7.65  in  cash. As  of January  6,  1994, all  directors and
executive officers  of the  Company as  a group  owned an  aggregate of  321,967
shares  of  Common  Stock,  including 230,887  shares  which  could  be acquired
pursuant to currently exercisable stock  options. See 'Principal and  Management
Stockholdings -- Security Ownership of Management' and 'Principal and Management
Stockholdings  --  Security Ownership  of  Directors and  Executive  Officers of
Holderbank, Holdernam and Holcem.'
 
     In connection  with  the  Merger,  a special  committee  of  the  board  of
directors  of Holderbank formed for the  purpose of considering the Merger acted
for such board of directors and each reference in this Disclosure Statement  and
Notice  to the board of  directors of Holderbank is  a reference to such special
committee. The special committee consisted of Thomas Schmidheiny, the  Chairman,
Managing  Director and  Chairman of the  Executive Committee  of Holderbank, Dr.
Anton E.  Schrafl, the  Deputy Chairman  of Holderbank,  Dr. Max  D. Amstutz,  a
Managing  Director of Holderbank  and Vice Chairman  of the Executive Committee,
Professor Dr. Angelo  Pozzi, a  director of  Holderbank and  director of  Motor-
Columbus AG of Switzerland, and Dr. Jean-Claude Wenger, a director of Holderbank
and  a lawyer. Except for Dr. Schrafl, who is a director of the Company and owns
250 shares of Common Stock, none of these persons has any interest in the Common
Stock or other securities of the  Company or other involvement with the  Company
except  through  his positions  with Holderbank.  See 'Principal  and Management
Stockholdings.' The special committee was advised that its responsibility was to
ensure fair value to the Public Stockholders, not the transaction most favorable
to Holderbank. The  special committee, with  the advice of  Merrill Lynch,  felt
fully  capable of discharging this duty to the Public Stockholders. The board of
directors of Holderbank has ratified the actions of the special committee.
 
OPINION OF FINANCIAL ADVISOR
 
     Holdernam retained Merrill Lynch to act as its exclusive financial  advisor
in  connection with the possible acquisition of all of the outstanding shares of
Common Stock (the 'Holnam Shares') not owned by Holdernam or its affiliates.  On
January  7,  1994,  Merrill  Lynch  delivered  its  oral  opinion,  subsequently
confirmed in a written opinion,  dated January 7, 1994,  to the Boards, that  on
the  basis of and  subject to the matters  set forth therein, as  of the date of
such opinion,  the proposed  cash consideration  to be  received by  the  Public
Stockholders  in the Merger is fair to  such stockholders from a financial point
of view (the 'Fairness Opinion'). No limitations were imposed by Holdernam  with
respect  to the investigations  made or procedures followed  by Merrill Lynch in
rendering the Fairness Opinion, except that Merrill Lynch was not authorized to,
and did not, solicit indications of interest  for the acquisition of all or  any
part of the Company.
 
     A  COPY OF  THE FAIRNESS  OPINION, WHICH  SETS FORTH  THE ASSUMPTIONS MADE,
MATTERS CONSIDERED AND LIMITS ON THE  REVIEW UNDERTAKEN, IS ATTACHED AS ANNEX  D
TO THIS DISCLOSURE STATEMENT AND NOTICE AND IS INCORPORATED HEREIN BY REFERENCE.
THE  SUMMARY  OF  THE  FAIRNESS  OPINION OF  MERRILL  LYNCH  SET  FORTH  IN THIS
DISCLOSURE STATEMENT AND NOTICE IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE
FULL TEXT  OF SUCH  OPINION. THE  PUBLIC  STOCKHOLDERS ARE  URGED TO  READ  SUCH
OPINION IN ITS ENTIRETY.
 
     Merrill  Lynch's opinion is directed only  to the fairness from a financial
point of view of the consideration to be received by the Public Stockholders  in
the  Merger. Merrill Lynch did not consider fairness to Holcem, Holdernam or the
stockholders  of  Holderbank.  The  consideration  to  be  paid  to  the  Public
Stockholders  in the Merger was  determined by the board  of directors of Holcem
and concurred in by the board of directors of each of Holdernam and Holderbank.
 
     In arriving at its opinion, Merrill Lynch, among other things, (1) reviewed
the Company's annual reports to stockholders  for the three fiscal years  ended,
and  its Annual Report on Form 10-K for the two fiscal years ended, December 31,
1992 and the  related audited  financial information included  therein, and  the
Company's  unaudited financial information and related Quarterly Reports on Form
10-Q for the  three-, six-and  nine-month periods ended  March 31,  June 30  and
September   30,  1993,  respectively;   (2)  reviewed  the   annual  reports  to
stockholders and related audited financial  information of St. Lawrence for  the
three  fiscal years ended  December 31, 1992;  (3) reviewed certain information,
including financial  projections, relating  to  the businesses,  earnings,  cash
flow,  assets and prospects of the  Company, based upon information furnished to
Merrill Lynch by the Company, and of St. Lawrence,
 
                                       12
 
<PAGE>
furnished to  Merrill Lynch  by  St. Lawrence;  (4) conducted  discussions  with
members  of senior management  of the Company and  St. Lawrence concerning their
respective businesses and prospects, and  conducted discussions with members  of
senior  management of  Holderbank and  Holdernam concerning  such businesses and
prospects; (5) reviewed the Registration Statement  on Form S-4 of the  Company,
including  the combined Proxy  Statement and Prospectus  dated February 14, 1990
included therein,  filed  with  the  Securities  and  Exchange  Commission  (the
'Commission')  in connection with the Ideal Merger; (6) reviewed the current and
historical market prices and trading activity for the Common Stock and  compared
them with that of certain publicly traded companies that Merrill Lynch deemed to
be  reasonably similar  to the Company,  in whole  or in part;  (7) reviewed the
current and  historical market  prices  and trading  activity  for the  Class  A
subordinate shares of St. Lawrence (the 'St. Lawrence Shares'); (8) compared the
results  of  operations of  the  Company with  those  of certain  companies that
Merrill Lynch deemed to  be reasonably similar  to the Company,  in whole or  in
part; (9) reviewed a draft dated January 6, 1994 of the Certificate of Ownership
and  Merger; (10) reviewed the Certificate of Designation relating to the Series
A Preferred Stock; (11) reviewed a draft dated January 6, 1994 of the Rule 13e-3
Transaction Statement, including  the Disclosure Statement  and Notice  included
therein, proposed to be filed with the Commission in connection with the Merger;
(12)  compared  the  financial terms  of  the transactions  contemplated  by the
January 6,  1994 draft  of the  Certificate  of Ownership  and Merger  with  the
financial  terms of certain  other business combinations  and other transactions
that Merrill Lynch deemed to be relevant; and (13) reviewed such other financial
studies and  analyses and  performed  such other  investigations and  took  into
account such other matters as it deemed necessary.
 
     In   preparing  its  opinion  Merrill   Lynch  relied  without  independent
verification upon  the  accuracy,  completeness and  fair  presentation  of  all
financial  and other  information provided to  it by  Holderbank, Holdernam, the
Company and St. Lawrence, including  information concerning certain tax  matters
relevant  to its analysis, or which was publicly available. In addition, Merrill
Lynch has not made an independent appraisal of any of the assets or  liabilities
of the Company or St. Lawrence or of the shares of St. Lawrence. With respect to
the  financial forecasts referred to above, Merrill Lynch assumed that they have
been reasonably  prepared  on  bases reflecting  the  best  currently  available
estimates and judgments of the management of the Company or St. Lawrence, as the
case  may  be, as  to the  future financial  performance of  the Company  or St.
Lawrence, as  the  case  may be,  and  that  the management  of  Holderbank  and
Holdernam  concur in those  estimates and judgments.  Merrill Lynch's opinion is
based upon  general economic,  market,  monetary and  other conditions  as  they
existed and can be evaluated, and upon the information made available to Merrill
Lynch, as of the date of its opinion.
 
     The  matters considered  by Merrill  Lynch in  arriving at  its opinion are
based upon  numerous  macroeconomic,  operating and  financial  assumptions  and
involve  the  application of  complex methodologies  and educated  judgment. Any
estimates incorporated  in  the analyses  performed  by Merrill  Lynch  are  not
necessarily  indicative of actual past or future values or results, which may be
significantly more or less  favorable than such  estimates. Estimated values  do
not  purport to be appraisals and do not necessarily reflect the prices at which
businesses or companies may be  sold in the future or  at which their shares  of
capital  stock may  trade in the  future. Because such  estimates are inherently
subject to uncertainty, none of Holderbank, Holdernam, Holcem, the Company,  St.
Lawrence,  Merrill Lynch  or any other  person assumes  responsibility for their
accuracy.
 
     The following is a  summary of certain  financial and comparative  analyses
performed  by Merrill  Lynch in  connection with  the Fairness  Opinion which it
discussed with the Boards. The summary of the financial and comparative analyses
set forth below does not  purport to be a  complete description of the  analyses
employed  by Merrill Lynch in reaching  its opinion. Merrill Lynch believes that
its analyses must be considered  as a whole and  that selecting portions of  its
analyses  and  of the  factors considered  by it,  without considering  all such
factors and analyses, could create a misleading view of the processes underlying
its opinion. Arriving at a fairness opinion is a complex process not necessarily
susceptible to partial or summary description.
 
     In delivering its  oral opinion  on January  7, Merrill  Lynch advised  the
Boards  that it could not give specific percentage weights to particular factors
in the following analyses. However, in  response to questions by members of  the
Boards,   Merrill  Lynch  noted  that  it   had  considered  (i)  going  concern
 
                                       13
 
<PAGE>
values calculated from the analysis of  companies comparable to the Company  and
the  discounted cash  flow analysis  of the  Company described  below relatively
important; (ii) both current and historical market prices of the Common Stock as
less important because for a thinly traded security like the Common Stock market
prices may be volatile and change rapidly while values of companies do not;  and
(iii)  net  book value  of  the Common  Stock  and liquidation  value relatively
unimportant because Merrill  Lynch had  been advised that  no consideration  had
been  given to liquidating the  assets of the Company  and Merrill Lynch was not
authorized to and did not solicit indications of interest for the acquisition of
all or  any part  of the  Company. In  addition, Merrill  Lynch noted  that  the
Company's  public  disclosure documents  indicate that  previous prices  paid by
Holdernam for Common  Stock were  between $4.00 and  $5.00 per  share. See  'The
Merger  -- Background  of the Merger  -- Holderbank's Investments  in the United
States and Canada.'
 
     Stock Trading History. Merrill Lynch  reviewed and analyzed the  historical
market  prices and trading activity and volume for the Holnam Shares and for the
St. Lawrence  Shares.  In addition,  Merrill  Lynch reviewed  and  analyzed  the
relationship  between movements of the prices of the Holnam Shares and movements
in the Standard & Poor's Industrials average of approximately 500 stocks and  of
the  prices  of  the St.  Lawrence  Shares  on the  Toronto  Stock  Exchange 300
Composite Price Index. As a result of its analysis, Merrill Lynch concluded that
the price of the Holnam Shares and the St. Lawrence Shares already reflected the
expectation of financial improvement in the  cement industry in general and  the
Company and St. Lawrence in particular.
 
     Stock  Market Analysis of the Company. Merrill Lynch determined the 52 week
high and low  closing prices of  the Holnam  Shares on the  NYSE. This  analysis
resulted in an equity reference range of $2.88 to $7.38 per Holnam Share.
 
     Analysis  of Selected  Comparable Publicly Traded  Companies. Merrill Lynch
compared certain  financial information  for the  Company to  the  corresponding
publicly  available  financial  information  of  certain  other  publicly traded
companies that  Merrill Lynch  believed to  be comparable  to the  Company.  The
companies  that Merrill  Lynch determined  comparable are  Lafarge Corp., Medusa
Corp. and Southdown Inc. For such companies, Merrill Lynch calculated  multiples
of  such  companies'  (i) current  stock  price  to projected  1994  fiscal year
earnings per share ('EPS'), (ii)  market capitalization (defined as the  product
of  primary shares outstanding and market  price, plus preferred equity and debt
and less cash and marketable securities) to projected 1994 fiscal year  earnings
before interest and taxes ('EBIT'), and (iii) market capitalization to projected
1994  fiscal year earnings before interest, taxes, depreciation and amortization
('EBITDA').
 
     An analysis of  the multiples  for the  group of  comparable companies,  as
adjusted  to exclude  certain results  that Merrill  Lynch considered anomalous,
yielded the following ranges of multiples: (1) stock price to 1994 EPS of  19.6x
to  23.0x (with a mean of 21.0x); (2) market capitalization to 1994 EBIT of 9.5x
to 15.7x (with a mean of 12.8x); and (3) market capitalization to 1994 EBITDA of
6.0x to 9.7x (with a mean of 8.0x).
 
     Merrill Lynch then calculated aggregate per share imputed equity values for
the Company  by  applying the  Company's  forecasted financial  results  to  the
multiples  derived from Merrill Lynch's analysis  described above. Based on this
analysis, Merrill Lynch calculated equity  reference ranges per Holnam Share  of
$6.30 to $7.39 (with a mean of $6.75) based on stock price to 1994 EPS, $3.73 to
$8.02  (with a mean of  $6.01) based on market  capitalization to 1994 EBIT, and
$4.24 to $8.53 (with a mean of  $6.56) based upon market capitalization to  1994
EBITDA.  In making this  calculation, and in calculating  the amounts per Holnam
Share described below, Merrill Lynch  assumed the conversion of all  outstanding
shares  of Series A Preferred Stock and  the exercise of all options exercisable
for Common Stock  at a price  below the closing  market price as  of January  4,
1994.
 
     No  company utilized by Merrill Lynch in the comparable company analysis is
identical to the  Company. Accordingly,  an analysis of  the results  of such  a
comparison  is not mathematical; rather,  it involves complex considerations and
judgments concerning  differences in  historical  and forecasted  financial  and
operating  characteristics of  the comparable  companies and  other factors that
could affect the public trading value of such companies and the Company.

     Discounted Cash Flow  Analysis. Merrill Lynch  performed a discounted  cash
flow  analysis of the  Company. In performing its  analysis, Merrill Lynch first
performed a  discounted cash  flow analysis  of the  Holnam Operations.  Second,
Merrill  Lynch  calculated the  present  value of  net  operating losses  of the
Company. Merrill Lynch then  calculated the value of  the St. Lawrence  Interest
using  three different methodologies: (i) a going concern value derived from the
present value of  a projected dividend  stream from the  St. Lawrence  Interest;
(ii)  a liquidation value  derived from a  discounted cash flow  analysis of St.
Lawrence; and  (iii)  the aggregate  stock  market  price of  the  St.  Lawrence
Interest. Finally, Merrill Lynch added the sum of the calculated value of Holnam
Operations  and the net operating losses to  each of the three calculated values
for the  St. Lawrence  Interest in  order to  calculate three  different  equity
ranges for the Company.
 
     Discounted  Cash  Flow Analysis  of  Holnam Operations.  In  performing its
discounted cash flow analysis of Holnam Operations, Merrill Lynch calculated  an
equity  value range for  Holnam Operations based  upon the present  value of the
projected stream of unlevered free cash  flow of Holnam Operations reflected  in
the Holnam Operations Projections. Merrill Lynch used discount rates of 8.92% to
12.92%  to calculate  the present  value of the  forecasted stream  of free cash
flows based upon variations of  up to plus or minus  2% of the weighted  average
cost of capital ('WACC') of Holnam Operations of 10.92%. Merrill Lynch used EBIT
multiples of 12.0x to 19.6x to calculate the present value of the terminal value
of  such cash flow  at year-end 2002.  The EBIT multiples  used by Merrill Lynch
were based on a ten  year average of EBIT multiples  in the cement industry  and
were  applied  to the  average  projected EBIT  of  Holnam Operations  from 1994
through 2002.  After  subtracting Holnam  Operations'  net debt,  Merrill  Lynch
calculated  the effect of an increase in  average cement prices projected by the
management of the Company by both $1.00 and $3.00 per ton (above, for example, a
projected average  1994 price  of $57.82  per  ton), in  each case  utilizing  a
discount  rate equivalent to the Company's WACC. Based on this analysis, Merrill
Lynch calculated an aggregate  equity reference range  for Holnam Operations  of
$309,311,000 to $564,509,000 (the 'Holnam Operations DCF Range').
 
     NOL Analysis. The management of the Company provided Merrill Lynch with net
operating loss carry forward figures as of January 1, 1994 that were expected to
be  available  to  the  Company  during  the  period  of  the  Holnam Operations
Projections. Applying  projected  taxable  income throughout  those  years,  and
assuming  a  40% tax  rate and  an  effective 2%  alternative minimum  tax rate,
Merrill Lynch  calculated  the present  value  of the  aggregate  effective  tax
savings  to the Company throughout the  projected period of $114,844,000 using a
discount rate of 10.92%,  based on the Company's  WACC (the 'NOL Amount').  This
calculated tax savings was then added to the Holnam Operations DCF Range.
 
     Going  Concern Value of St. Lawrence  Interest. Merrill Lynch calculated an
equity value for the St. Lawrence Interest  based upon the present value of  the
projected  dividends for the  St. Lawrence Interest  (the 'Projected Dividends')
for the fiscal years 1994 through 2002. These projections were jointly  prepared
by  the  management  of St.  Lawrence  and  Merrill Lynch  and  approved  by the
management of Holdernam. Merrill Lynch used a discount rate of 16.4%, reflecting
St. Lawrence's cost of equity to  calculate the present value of the  forecasted
dividend  stream. To calculate  the present value  of the terminal  value of the
dividend stream  at  year-end  2002,  Merrill  Lynch  assumed,  based  upon  the
assessment  of St. Lawrence management and Merrill Lynch that long term dividend
growth would be driven primarily by  inflation, a perpetual growth rate of  4.0%
of  the average  of the  Projected Dividends  from 1994  to 2002.  Based on this
analysis, Merrill Lynch calculated an equity value for the St. Lawrence Interest
of $54,180,000 (the  'St. Lawrence  Going Concern Amount').  Merrill Lynch  then
combined  this amount with the Holnam Operations DCF Range and the NOL Amount to
arrive at an equity reference range of $3.34 to $4.52 per Holnam Share.
 
     Discounted Cash  Flow  Analysis of  St.  Lawrence Interest.  Merrill  Lynch
performed  a  discounted  cash  flow  analysis  with  respect  to  St.  Lawrence
substantially similar to that performed on the Holnam Operations but based  upon
the stream of unlevered free cash flow in the St. Lawrence Projections and using
a  discount rate equal to St. Lawrence's WACC  of 11.35% and a terminal value of
14.8x based  on  the ten  year  industry  average EBIT.  After  subtracting  St.
Lawrence's  net  debt, Merrill  Lynch calculated  the effect  of an  increase in
average cement prices projected by the  management of St. Lawrence of both  Can.
$1.00  and Can. $3.00  per metric ton  (above, for example,  a projected average
1994 price of Can.  $69.37 per metric  ton), in each  case utilizing a  discount
rate equivalent to St. Lawrence's WACC. Based
 
                                       15
 
<PAGE>
on this analysis, Merrill Lynch calculated an equity reference range for the St.
Lawrence  Interest  of  $162,991,000  to  $207,582,000  (the  'St.  Lawrence DCF
Range'). Merrill Lynch then combined this amount with the Holnam Operations  DCF
Range  and the  NOL Amount to  arrive at an  equity reference range  of $4.09 to
$5.59 per Holnam Share.
 
     Stock Market Analysis of St. Lawrence. Merrill Lynch determined the January
5, 1994 closing price of the St. Lawrence Shares on the Toronto stock  exchange.
A  percentage  of this  amount reflecting  the St.  Lawrence Interest  (the 'St.
Lawrence Market Amount') was then combined with the Holnam Operations DCF  Range
and  the NOL Amount to arrive at an equity reference range of $4.52 to $5.70 per
Holnam Share.
 
     Comparable Acquisition Analysis. Merrill Lynch reviewed the financial terms
of six recent acquisition transactions  that it viewed as reasonably  comparable
to  an acquisition  of Holnam  Operations. The  acquisitions that  Merrill Lynch
deemed   comparable   are   Holnam   Inc./Midlothian,   Medusa/Lafarge    Plant,
Ssangyong/Riverside,  Beazer/Gifford-Hill, Lafarge/Missouri Davenport and Cement
Mexicanos/Pacific Coast (Lone Star). Due to the scarcity of recent  acquisitions
involving  large  multiplant cement  companies like  Holnam Operations,  many of
these comparable  acquisitions  concern  the  purchase  of  specific  production
facilities.
 
     Merrill Lynch divided the transaction value (derived by adding the purchase
price and any assumption of debt) of each comparable acquisition by the capacity
of  cement production for each acquired entity, arriving at an acquisition price
per ton of cement  production capacity for each  acquired entity. Merrill  Lynch
did  not take into account cost  of production in its analysis  due to a lack of
reliable public information on the acquisition targets.
 
     Merrill Lynch then multiplied Holnam Operations' cement production capacity
(excluding minority  interests)  by  the  high,  low  and  mean  price  per  ton
calculated  for  the comparable  acquired entities,  added  the value  of Holnam
Operations' non-cement  assets and  subtracted net  debt. Using  this  analysis,
Merrill  Lynch calculated  an equity  reference range  for Holnam  Operations of
$226,206,000 to  $754,298,000.  After  adding  the  NOL  Amount,  Merrill  Lynch
combined this range with the St. Lawrence Going Concern Amount, the St. Lawrence
DCF  Range, and the  St. Lawrence Market  Amount, to arrive  at equity reference
ranges of $2.76 to $6.43, $3.52 to $7.19 and $3.94 to $7.62, respectively.
 
     Holdernam selected Merrill Lynch as  its financial advisor because  Merrill
Lynch  is an internationally  recognized investment banking  firm engaged in the
valuation of  businesses and  their securities  in connection  with mergers  and
acquisitions   and  for  other  purposes   and  has  substantial  experience  in
transactions similar  to the  Merger.  Pursuant to  an engagement  letter  dated
December  10, 1993 with  Merrill Lynch, Holdernam paid  Merrill Lynch an initial
fee for its advisory  services of $225,000 and  became obligated to pay  Merrill
Lynch  an  additional  fee  of  $500,000 upon  consummation  of  the  Merger. In
addition, the engagement letter provides that the Company will reimburse Merrill
Lynch for its reasonable out-of-pocket  expenses (including reasonable fees  and
disbursements of its legal counsel) and will indemnify Merrill Lynch and certain
related persons against certain liabilities arising out of its engagement.
 
     Merrill  Lynch has  in the past  provided financial  advisory and financing
services to Holderbank and received customary fees for rendering such  services.
In the ordinary course of its business, Merrill Lynch may also actively trade in
securities  of both the Company and St. Lawrence for its own account and for the
account of its customers and, accordingly, may at any time hold a long or  short
position in such securities.
 
     Neither  Holcem, the Company nor, except as described herein, Holdernam has
currently or has had within the past two years or hereafter contemplates  having
any  material relationship with Merrill Lynch  or any of its affiliates. Merrill
Lynch was a co-managing underwriter of an offering of Holderbank's  Subordinated
Convertible  Bonds  made in  July 1993  and  received customary  compensation in
connection therewith.  Holderbank  currently has  no  definite plans  to  retain
Merrill Lynch in the future.
 
     The  Fairness Opinion, as  well as the  Merrill Lynch presentation material
related thereto and the Goldman Sachs Presentation Material and the November  15
Presentation Material, are available for inspection and copying at the principal
executive  offices of Holcem during its regular business hours by any interested
Public Stockholder or his representative who has been so designated in  writing.
A copy

of  any  of the  Fairness  Opinion or  the  Merrill Lynch  presentation material
related thereto or the  Goldman Sachs Presentation Material  or the November  15
Presentation  Material will  be transmitted by  Holcem to  any interested Public
Stockholder or his  representative who has  been so designated  in writing  upon
written request and at the expense of the requesting stockholder.
 
POTENTIAL DETRIMENTS AND ADVERSE EFFECTS OF THE MERGER
 
     If  the  value  of  the  Company increases  after  the  Merger,  the Public
Stockholders will not have the opportunity to benefit from that increase.  Since
the Common Stock will no longer be publicly traded after the Merger, the Company
will  not have  access to  public U.S.  capital markets  unless it  elects to go
public again in  the future and  its financing flexibility  will to some  extent
thereby  be reduced. However, the absence of public stockholders is not expected
to diminish the Company's opportunities to obtain private financing.
 
STOCK OPTIONS AND BENEFIT PLANS
 
     There are currently  outstanding under  the Holnam Inc.  1990 Stock  Option
Plan  (the 'Stock Option Plan') employee  stock options (including related stock
appreciation rights)  to purchase  623,667  shares of  Common Stock.  These  are
comprised  of options to purchase  451,667 shares at an  exercise price of $7.25
per share  that were  granted on  March 23,  1990, options  to purchase  132,000
shares at an exercise price of $5.75 per share that were granted on May 16, 1991
and  options to purchase 40,000 shares at  an exercise price of $4.375 per share
that  were  granted  on  August  15,  1991.  All  such  options  are   currently
exercisable.
 
     Pursuant  to the power granted to it under the Stock Option Plan, the Board
of Directors of the Company  has amended all such  options to provide that  they
will  terminate if not exercised  by the Effective Time  of the Merger. However,
with respect to any option that is not exercised prior to the Effective Time  of
the  Merger,  Holdernam will  cause the  Company, upon  surrender of  the option
agreement, to make  a cash payment  to the optionee  in an amount  equal to  the
number of shares of Common Stock covered by such option immediately prior to the
Effective  Time of the Merger multiplied by the difference between the per share
exercise price of  their options  and the highest  closing sales  price for  the
Common  Stock on the NYSE from January 6, 1994 through the Effective Time of the
Merger. If such  highest NYSE  closing sales  price is  $7.75 and  none of  such
options  is exercised prior to  the Effective Time of  the Merger, the aggregate
amount of such  payments will  be $624,833.50. Funds  for this  purpose will  be
furnished  by Holdernam to the Company, in trust, for the benefit of the holders
of such options on the  same terms as funds  for payment to Public  Stockholders
are furnished to the Paying Agent. See 'The Merger -- Payment for Shares.'
 
     In  addition to  the options granted  under the Stock  Option Plan, options
held by certain former key  employees of Ideal at the  time of the Ideal  Merger
were  repriced and adjusted in connection  with the Ideal Merger. These options,
which  were  issued  at  exercise  prices  of  $9.50  and  $11.00  (each   being
considerably  higher  than  the  price  per  share  to  be  paid  to  the Public
Stockholders in connection with the Merger), are essentially valueless and  will
be  canceled at  the Effective  Time of  the Merger  by action  of the  Board of
Directors of the Company.
 
     Pursuant to the Holnam Inc. 1990  Employee Stock Purchase Plan (the  'Stock
Purchase  Plan'), certain  eligible employees of  the Company  may subscribe for
originally-issued shares  of Common  Stock at  a purchase  price of  90% of  the
market  price (as defined) of the Common Stock  on the last business day of each
six-month purchase period.  Payment of the  purchase price for  these shares  is
made by participating employees in installments through payroll deductions. Each
of  the shares of Common Stock purchased pursuant to the Stock Purchase Plan and
held by participating  employees at  the Effective Time  of the  Merger will  be
converted  into the right to receive $7.65 in cash. The Stock Purchase Plan will
be terminated in connection with the Merger by action of the Board of  Directors
of the Company.

<PAGE>
PAYMENT FOR SHARES
 
     Holdernam  has selected American  Stock Transfer &  Trust Company as paying
agent (the 'Paying Agent') to make payments for shares of Common Stock. A letter
of transmittal  containing instructions  with respect  to the  surrender of  the
stock certificates is enclosed herewith. After the Effective Time of the Merger,
there will be no further transfers on the stock transfer books of the Company of
shares of Common Stock which were outstanding immediately prior to the Effective
Time of the Merger. When a certificate representing such shares is presented for
transfer,  it will be canceled and a  check representing the value of the Common
Stock will be issued in exchange therefor.
 
     The conversion of  the Common  Stock into the  right to  receive cash  will
occur at the Effective Time of the Merger without regard to the date or dates on
which  certificates for shares of Common  Stock are physically surrendered. Each
certificate representing outstanding shares of Common Stock immediately prior to
the Effective Time of the  Merger (other than shares  owned by Holcem) will,  at
the  Effective  Time of  the Merger,  be  deemed for  all corporate  purposes to
represent the right to receive cash in lieu of such shares of Common Stock.
 
     Until a certificate which  formerly represented shares  of Common Stock  is
actually  surrendered to  and received by  the Paying Agent,  the holder thereof
will not be entitled to receive the cash consideration to which he is  entitled.
Subject  to  applicable  law,  upon such  surrender  of  the  certificates, such
payments will be remitted  (without interest) to the  record holder, net of  any
withholding  taxes that  may be  applicable. All  cash consideration  payable to
holders of record of Common Stock after the Effective Time of the Merger will be
paid by  Holdernam to  the  Paying Agent,  in trust,  for  the benefit  of  such
holders. All such amounts held by the Paying Agent which remain unclaimed at the
end  of one  year after the  Effective Time  of the Merger  will be  paid to the
Company after which time the Company will act as paying agent and any holder  of
a   certificate  which  formerly  represented  Common  Stock  will,  subject  to
applicable law, be entitled to  look as a general  creditor only to the  Company
for  payment. However, neither the Company,  Holdernam nor the Paying Agent will
be liable  to a  holder of  Common  Stock for  any cash  delivered to  a  public
official pursuant to applicable escheat laws.
 
AMENDMENT AND ABANDONMENT
 
     The board of directors of Holcem may at any time prior to the filing of the
Certificate  of Ownership and Merger with the Secretary of State of the State of
Delaware amend  or  supplement the  Certificate  of Ownership  and  Merger.  Any
amendment or supplement to the Certificate of Ownership and Merger made prior to
such  filing that is material to the  Public Stockholders will be the subject of
additional disclosure material.
 
     The board of directors of Holcem may also at any time prior to such  filing
terminate  and abandon  the Merger  for any  reason sufficient  unto itself. The
board of directors of  Holcem does not currently  intend to amend or  supplement
the Certificate of Ownership and Merger or terminate and abandon the Merger.
 
SOURCE OF FUNDS; EXPENSES
 
     Holderbank  will provide the necessary funds to pay the Public Stockholders
for the shares of Common  Stock held by them, to  make payments with respect  to
employee  stock options  and to pay  the costs  and expenses of  the Merger. The
aggregate of such  amounts is expected  to be approximately  $54,275,776 if  all
stock options are exercised and no Public Stockholders perfect their dissenters'
appraisal rights and approximately $53,775,677 if no stock options are exercised
and no Public Stockholders perfect their dissenters' appraisal rights.
 
     Holderbank  will borrow such funds under existing lines of credit which are
more than  sufficient  for  this  purpose.  Holderbank  will  make  these  funds
available to Holdernam as a contribution to the capital of Holdernam.
 
     All  costs and  expenses incurred by  Holcem, Holdernam,  Holderbank or the
Company in connection with the  Merger, including Commission filing fees,  legal
fees  and expenses, accounting fees  and expenses, printing expenses, investment
banker's   fees   and    expenses   and    the   Paying    Agent's   fees    and
 
                                       18
 
<PAGE>
expenses, will be paid by Holdernam from such funds provided by Holderbank. Such
costs  and  expenses  are  estimated  to  be  approximately  $1,200,000  in  the
aggregate.
 
PLANS AND PROPOSALS
 
     Following the  Merger, subject  to obtaining  any amendments,  consents  or
waivers of the provisions in the Company's debt instruments that may be required
as  well as to the Company's ability  to provide necessary funding on acceptable
terms, the Company may amend its restated certificate of incorporation so as  to
permit  the  redemption  of  its preferred  stock  before  it  currently becomes
redeemable, which is May 15, 1997.
 
THE COMPANY'S POST-MERGER CAPITAL STOCK
 
     In the Merger, the Company's restated certificate of incorporation will  be
amended  to change  the capital  stock the Company  is authorized  to issue. The
number of authorized  shares of Common  Stock will be  reduced from  200,000,000
shares  to 2,000 shares, of which 1,000  will be issued to Holdernam. The number
of authorized shares of preferred stock  will be reduced from 50,000,000  shares
to  2,000 shares,  of which  1,034.71333 shares,  having rights  and preferences
equal to the rights and preferences (including liquidation and redemption value)
of the 620,828 shares of Series A Preferred Stock currently held by Holcem, will
be issued  to  Holdernam. These  changes  to  the Company's  capital  stock  are
expected  to reduce  the annual  franchise taxes payable  by the  Company to the
State of  Delaware by  up to  $149,000 and  permit the  Company to  pay less  of
similar  taxes  to  other states  in  the  United States  where  the  Company is
authorized to transact business.
 
REPORTING REQUIREMENTS AND EXCHANGE LISTING
 
     As a result of the Merger, the  Company will have only one stockholder  and
will  be  able and  intends  to terminate  its  reporting obligations  under the
Securities Exchange Act of 1934, as amended (the 'Exchange Act'), and to  remove
the Common Stock from listing on the NYSE.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The   following  summary   describes  the   material  Federal   income  tax
consequences to the Public  Stockholders who are citizens  and residents of  the
United States. It does not discuss all the tax consequences that may be relevant
to  the  Public Stockholders  entitled to  receive  special treatment  under the
Internal Revenue Code of 1986, as amended (such as insurance companies,  foreign
persons  and tax-exempt organizations),  or to Public  Stockholders who acquired
their shares of Common Stock pursuant to the exercise of employee stock  options
or otherwise as compensation.
 
     Under  present law, the Merger of Holcem  with and into the Company will be
treated for Federal income  tax purposes as a  taxable purchase by Holdernam  of
the Company's stock from the Public Stockholders.
 
     Gain  or  loss will  be recognized  by the  Public Stockholders  upon their
receipt of  cash in  exchange for  their Common  Stock equal  to the  difference
between  the  cash received  and  the Public  Stockholders'  basis in  the stock
exchanged. Such gain or loss will be characterized as capital gain or loss to  a
Public  Stockholder if the Common  Stock being exchanged was  a capital asset in
the hands of such Public Stockholder, and will be long-term capital gain or loss
if such stock was held by such Public Stockholder for a period of more than  one
year.
 
     The  Merger will  not give  rise to  any taxable  gain or  loss for Federal
income tax purposes to the Company, Holdernam, Holderbank or Holcem.
 
     A ruling has  not been  requested from  the Internal  Revenue Service  (the
'IRS')  with regard to any of the  Federal income tax consequences of the Merger
and the statements as to the Federal  income tax consequences of the Merger  set
forth above will not be binding on the IRS.
 
     THE  FOREGOING IS ONLY A GENERAL DESCRIPTION OF THE MATERIAL FEDERAL INCOME
TAX    CONSEQUENCES   OF    THE    MERGER   WITHOUT  REGARD   TO  THE   PARTICU-
                                       19

LAR FACTS AND CIRCUMSTANCES OF  EACH PUBLIC STOCKHOLDER'S TAX SITUATION.  PUBLIC
STOCKHOLDERS  OF THE COMPANY ARE  URGED TO CONSULT THEIR  OWN TAX ADVISORS AS TO
THE FEDERAL INCOME TAX CONSEQUENCES  OF THE MERGER TO THEM,  AND ALSO AS TO  ANY
STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES.
 
APPRAISAL RIGHTS
 
     THE  FOLLOWING SUMMARY  OF THE  RIGHTS OF  THE PUBLIC  STOCKHOLDERS SEEKING
APPRAISAL UNDER  SECTION 262  OF THE  DGCL DOES  NOT PURPORT  TO BE  A  COMPLETE
STATEMENT  THEREOF  AND  IS  QUALIFIED  IN  ITS  ENTIRETY  BY  REFERENCE  TO THE
APPLICABLE STATUTORY  PROVISIONS  OF  THE  DGCL,  WHICH  ARE  ATTACHED  TO  THIS
DISCLOSURE STATEMENT AND NOTICE AS ANNEX E.
 
     If  the Merger is  consummated, a holder  of record of  Common Stock at the
Effective Time of  the Merger who  has followed the  procedures set forth  under
Section  262 of the DGCL ('Section 262') will  be entitled to have any or all of
his shares of  Common Stock appraised  by the Delaware  Court of Chancery  under
Section  262. Section  262 represents  the exclusive  statutory remedy available
under Delaware law to holders of Common Stock who elect to seek appraisal of the
fair value of their  shares. Persons who are  beneficial owners of Common  Stock
but whose shares are held of record by another person, such as a broker, bank or
nominee,  should  timely  instruct the  record  holder to  follow  the procedure
outlined below if such persons wish to seek appraisal with respect to any or all
of their shares. Failure to take any necessary step may result in a  termination
or waiver of appraisal rights under Section 262.
 
     A  holder of record  of Common Stock electing  to exercise appraisal rights
under Section 262  must deliver  a written demand  for appraisal  of his  Common
Stock  to the Company prior to February 22, 1994, the proposed Effective Time of
the Merger. The written  demand must be  mailed or delivered  to the Company  at
6211  North Ann Arbor  Road, Dundee, Michigan 48131,  Attention: Robert J. Moir,
Esq. Such written demand must reasonably  inform the Company of the identity  of
the  stockholder of record  and that such stockholder  intends thereby to demand
the appraisal of his shares of Common Stock.
 
     Only the holder of record of Common Stock is entitled to seek appraisal  of
the  fair value for the shares registered  in such holder's name. The demand for
appraisal must be executed by or for the holder of record, fully and  correctly,
as  such holder's name appears on the  holder's stock certificates. If the stock
is owned of record in  a fiduciary capacity, such as  by a trustee, guardian  or
custodian, the demand should be made in that capacity, and if the stock is owned
of  record by more than one person, as  in a joint tenancy or tenancy in common,
the demand should be made by or  for all owners of record. An authorized  agent,
including  one of two or more joint owners, may execute the demand for appraisal
for a holder of record;  however, such agent must  identify the record owner  or
owners  and expressly state, in  such demand, that the  agent is acting as agent
for the record owner or owners of such shares.
 
     A record holder, such as a broker, who holds Common Stock as a nominee  for
beneficial  owners,  some  of whom  desire  to demand  appraisal,  must exercise
appraisal rights on behalf of such beneficial owners with respect to the  shares
held  for such beneficial  owners. In such  case, the written  demand should set
forth the number  of shares  of Common  Stock covered  thereby. Otherwise,  such
demand  will be  presumed to cover  all shares held  in the name  of such record
owner.
 
     Within 120 days after the Effective Time of the Merger, the Company or  any
Public  Stockholder who has  complied with the  applicable provisions of Section
262 and who  is otherwise entitled  to appraisal rights  under Section 262,  may
file  a petition in the Delaware Court  of Chancery demanding a determination of
the value of the Common Stock of all the Public Stockholders seeking  appraisal.
Public  Stockholders seeking to exercise appraisal rights should not assume that
the Company will file a petition with respect to the appraisal of the fair value
of the shares  of Common Stock  of such  stockholders or that  the Company  will
initiate  any  negotiations  with respect  to  the  fair value  of  such shares.
Accordingly, Public  Stockholders  should  initiate all  necessary  action  with
respect  to the perfection of their appraisal rights within the time periods and
in the manner prescribed in Section 262.
 
                                       20
 
<PAGE>
     Within 120  days  after  the  Effective Time  of  the  Merger,  any  Public
Stockholder  who has complied with the above-described provisions of Section 262
is entitled,  upon written  request, to  receive from  the Company  a  statement
setting  forth the aggregate  number of shares  of Common Stock  with respect to
which demands for appraisal have been received by the Company and the  aggregate
number  of holders of such shares. Such  written statement must be mailed to the
stockholder within ten days after his written request therefor has been received
by the  Company or  within ten  days after  the Effective  Time of  the  Merger,
whichever is later.
 
     If  such petition for a determination of  the value of the shares of Common
Stock of Public  Stockholders entitled to  appraisal rights is  timely filed  as
discussed  above,  after  a hearing  on  such  petition, the  Delaware  Court of
Chancery will determine the Public Stockholders entitled to appraisal rights and
will appraise the shares of Common Stock owned by such stockholders, determining
the fair value of such shares exclusive of any element of value arising from the
accomplishment or  expectation of  the  Merger, together  with  a fair  rate  of
interest,  if any, to be paid on the  amount determined to be the fair value. In
determining fair value, the Delaware Court  of Chancery is to take into  account
all  relevant factors.  Upon application of  a Public  Stockholder, the Delaware
Court of Chancery may order  that all or a portion  of the expenses incurred  by
any  Public Stockholder in connection  with the appraisal proceeding, including,
without limitation,  reasonable attorneys'  fees and  the fees  and expenses  of
experts  utilized in the  appraisal proceeding, be charged  pro rata against the
value of all shares of Common Stock entitled to appraisal.
 
     Any Public Stockholder who has  duly demanded appraisal in compliance  with
Section  262 will not,  after the Effective  Time of the  Merger, be entitled to
vote the shares of  Common Stock subject  to such demand for  any purpose or  to
receive  payment of dividends or other  distributions on such shares, except for
dividends or other distributions payable to Public Stockholders of record as  of
a day prior to the Effective Time of the Merger.
 
     A  Public Stockholder  will effectively lose  his right to  appraisal if no
petition for appraisal  is filed in  the Delaware Court  of Chancery within  120
days  after the Effective Time of the  Merger. A Public Stockholder may withdraw
his demand for appraisal within 60 days  after the Effective Time of the  Merger
by  delivering to the Company a  written withdrawal of such stockholder's demand
for an appraisal and an acceptance of  the Merger, and may withdraw such  demand
for appraisal thereafter with the written approval of the Company.
 
     In   the  event  an  appraisal  proceeding  is  properly  instituted,  such
proceeding may not be dismissed as to any Public Stockholder who has established
his right of appraisal under the provisions of Section 262 without the  approval
of the Delaware Court of Chancery, and any such approval may be conditioned upon
such terms as the Court of Chancery deems just.
 
     FAILURE  TO  TAKE ANY  REQUIRED  STEP IN  CONNECTION  WITH THE  EXERCISE OF
APPRAISAL RIGHTS MAY RESULT IN  THE TERMINATION OF SUCH  RIGHTS. IN VIEW OF  THE
COMPLEXITY  OF  THESE  PROVISIONS  OF  THE  DGCL,  PUBLIC  STOCKHOLDERS  WHO ARE
CONSIDERING EXERCISING THEIR RIGHTS UNDER SECTION 262 SHOULD CONSULT THEIR LEGAL
ADVISORS.
 
     This Disclosure Statement  also constitutes  notice by the  Company to  the
Public  Stockholders  pursuant to  Section 262(d)(2)  that appraisal  rights are
available for any or all of the shares of Common Stock owned by them.
 
STOCKHOLDERS' LITIGATION
 
     On January 14, 1994, the Company and Holdernam, together with the directors
of  the  Company,  were  served  with  two  substantially  similar   complaints,
purportedly  brought  as class  actions by  alleged  Public Stockholders  of the
Company on behalf  of themselves  and all  other stockholders  except for  those
'related  to  or affiliated  with' any  defendant. Schulman  v. Holnam  Inc. and
Holdernam Inc., et  al., C.A.  No. 13336  (Del. Ch.  filed Jan.  13, 1994);  and
Hartman  v. Holnam  Inc. and Holdernam  Inc., et  al., C.A. No.  13324 (Del. Ch.
filed Jan. 10,  1994). Both  complaints allege  breaches of  fiduciary duty  and
conflicts of interest under Delaware law as well as failure to disclose material
non-public information as to the value of the Common Stock. Each complaint prays
for  preliminary as well  as permanent injunctive  relief and, in  the event the
Merger  is  consummated,  recision  plus   the  award  of  rescissory   damages.

Though  defendants  have not  yet been  served  with any  additional complaints,
counsel for plaintiffs  as well  as the court  clerk's office  in Delaware  have
advised  counsel for  defendants that  at least  two more  substantially similar
complaints have been filed, but not yet served, and defendants' counsel  further
believe that a third such additional complaint is soon to be filed.
 
     Counsel  for defendants and  representatives of counsel  for each plaintiff
have conferred and  agreed to propose  to the Delaware  Court consolidation  for
purposes  of  discovery  as well  as  trial  of all  such  substantially similar
proceedings. In addition, on  January 19, 1994,  defendants' counsel was  served
with  an Amended Class  Action Complaint which  the parties will  propose to the
court as the Consolidated Complaint (a copy of which is available to any  Public
Stockholder upon written request to Holcem).
 
     Named  as defendants in the Amended Class Action Complaint are the Company,
Holcem and  Holdernam,  as well  as  three  individuals, Peter  Byland  and  Max
Amstutz,  directors  of each  of  the three  corporate  defendants and  Anton E.
Schrafl, a director of the Company as well as a member of the special  committee
of  the Holderbank Board that  approved the price of $7.65  as fair value to the
Public Stockholders.  The  Amended  Class Action  Complaint  alleges  that  'the
proposed  merger is in furtherance of a  fraudulent plan to take Holnam private,
violates the fiduciary  duties to the  Holnam minority, and  has been timed  and
structured  unfairly in that'

     --  Members  of the Class  would be eliminated as Public Stockholders at  a
         price per share which defendants knew or know is unfair and inadequate;
 
     --  Holderbank  and  Holcem,  aided   and   abetted   by   the   individual
         defendants,  have  structured and  timed the transaction  in an  unfair
         manner and have  engaged in unfair dealing;
 
     --  Holdernam and Holcem have unique knowledge  of the  Company  and   have
         access  to  information denied or  unavailable to  the  Class.  Without
         all  material  information,  Class  members  are  unable  to  determine
         whether the  price  offered  in the transaction is fair or whether they
         should seek appraisal;  and
 
     --  Finally, defendants control  the Company  and it is  unfair  as well as
         a violation of their fiduciary duties to consummate the  Merger without
         first obtaining the recommendation  and  input  by  a truly independent
         representative of the Public Stockholders or otherwise ensuring  a fair
         price is offered.
 
     By  way of  relief, the Amended  Complaint seeks  preliminary and permanent
injunctive relief against consummation of the Merger. Further, in the event  the
Merger  is consummated, the Amended Complaint prays for rescission of the Merger
and rescissory damages. Counsel for defendants believe the Amended Complaint  to
be without merit and each defendant intends to contest its various claims.
 
     Finally,  counsel  for  defendants  and counsel  for  plaintiffs  intend to
cooperate in endeavoring  to agree upon  a schedule for  expedited discovery  to
enable a hearing on any motion for preliminary relief that plaintiffs may decide
to  press in advance of February 22, 1994,  the date the Merger is now scheduled
to take place.

HOLDERS
 
     The approximate number of record holders of the Common Stock as of  January
6, 1994 was 6,260.
 
DIVIDENDS
 
     The  Company has paid no dividends on  its Common Stock during the past two
fiscal years.  Certain of  the Company's  debt instruments  presently limit  the
Company's  ability to  pay dividends on  the Common Stock.  The most restrictive
such limit provides that the Company may  declare and pay cash dividends on  the
Common  Stock up to a maximum of $15,000,000  in any fiscal year if the ratio of
earnings before interest,  taxes, depreciation and  amortization (excluding  St.
Lawrence) to interest expense (excluding St. Lawrence) is 3.00 or greater. Under
this  limit, the Company was not permitted to pay cash dividends with respect to
1992 and is not expected to be  permitted to pay cash dividends with respect  to
1993.  Payment of dividends is otherwise  within the discretion of the Company's
Board of Directors  and will depend  on the earnings,  capital requirements  and
operating and financial condition of the Company, among other factors.
 
                       RATIO OF EARNINGS TO FIXED CHARGES
 
     For  the purpose  of calculating  the ratio  of earnings  to fixed charges,
earnings consist of  the amount  of fixed  charges plus  earnings before  income
taxes and extraordinary items. Fixed charges consist of interest and the portion
of  rent  deemed representative  of  the interest  factor.  For the  years ended
December 31,  1991  and 1992  and  the nine  months  ended September  30,  1993,
earnings  as defined were less than fixed charges by approximately $115,570,000,
$66,112,000 and $3,073,000, respectively.
 
                              BOOK VALUE PER SHARE
 
     The Company's book value per share as of December 31, 1992 was $3.23 and as
of September 30, 1993 was $2.69.

(1) As used in this table, 'beneficial ownership' means the sole or shared power
    to  vote, or  to direct  the voting of,  a security,  or the  sole or shared
    investment power with respect to a security (i.e., the power to dispose  of,
    or  to direct the disposition of, a  security). In addition, for purposes of
    this table,  a  person  is deemed,  as  of  any date,  to  have  'beneficial
    ownership'  of any security that such person has the right to acquire within
    60 days after such date.
 
(2) Holcem  is  a   wholly-owned  subsidiary  of   Holdernam.  Holdernam  is   a
    wholly-owned  subsidiary of Holderbank. Holderbank  has presently issued and
    outstanding 14,100,000  shares of  voting stock.  Of these,  10,100,000  are
    registered  shares and 4,000,000 non-registered or bearer shares. Holders of
    bearer shares are  not generally  known by Holderbank.  However, holders  of
    registered  shares can  be identified.  Based on  the share  register, Swiss
    entities controlled by Mr. Thomas  Schmidheiny and Societe Suisse de  Ciment
    Portland  S.A.,  a publicly-held  Swiss corporation  ('SSCP'), are  the sole
    holders of registered  shares corresponding to  more than 5%  of the  voting
    stock   of   Holderbank.  Through   various   Swiss  entities,   legally  or
    beneficially,  directly  or   indirectly,  Mr.   Thomas  Schmidheiny   holds
    approximately  48% of Holderbank's voting stock and SSCP holds approximately
    9% of Holderbank's voting stock. Mr. Schmidheiny is also a director of SSCP.
    SSCP's address is  23, Faubourg de  l'hopital, 2000 Neuchatel,  Switzerland.

the related consolidated  statements of  income, stockholders'  equity and  cash
flows  for each of the three years in  the period ended December 31, 1992. These
financial  statements  are  the  responsibility  of  Holnam's  management.   Our
responsibility  is to express an opinion  on these financial statements based on
our audits. We  did not audit  the financial statements  of St. Lawrence  Cement
Inc.,   which  statements  reflect  assets  constituting  43%  and  42%  of  the
consolidated totals as of December 31, 1992 and 1991, respectively, and revenues
constituting 42%, 47%  and 52% of  the consolidated totals  for the years  ended
December  31,  1992, 1991  and 1990,  respectively.  Those statements,  prior to
reflecting certain adjustments to conform and translate such statements to  U.S.
generally  accepted accounting  principles using  U.S. dollars,  were audited by
other auditors whose reports have been furnished to us, and our opinion, insofar
as it relates to the amounts included for that entity, is based solely upon  the
reports of the other auditors.
 
     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  and the  reports  of  other  auditors  provide a
reasonable basis for our opinion.
 
     In our opinion, based on our audits and the reports of other auditors,  the
financial statements referred to above present fairly, in all material respects,
the  financial position of Holnam Inc. and  subsidiaries as of December 31, 1992
and 1991, and the results of their  operations and their cash flows for each  of
the  three  years in  the period  ended  December 31,  1992, in  conformity with
generally accepted accounting principles.
 
     Our audits were made  for the purpose  of forming an  opinion on the  basic
consolidated  financial statements taken as a whole. The schedules listed in the
accompanying index  are  the  responsibility  of  Holnam's  management  and  are
presented   for  purposes  of   complying  with  the   Securities  and  Exchange
Commission's rules  and  are  not  part  of  the  basic  consolidated  financial
statements.  These  schedules have  been  subjected to  the  auditing procedures
applied in our audits of the basic consolidated financial statements and, in our
opinion, based on our audits and the reports of other auditors, fairly state, in
all material respects, the  financial data required to  be set forth therein  in
relation to the basic consolidated financial statements taken as a whole.

the  Company's management. Our responsibility is  to express an opinion on these
financial statements based on our audits.
 
     We conducted  our audits  in accordance  with generally  accepted  auditing

                          HOLNAM INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) BACKGROUND
 
     Holnam  Inc. and its  subsidiaries (Holnam) are  involved in the production
and sale  of cement  and certain  related  products. As  of December  31,  1992,
approximately  95.2% of  the outstanding  shares of  common stock  were owned by
Holdernam Inc. (Holdernam). Holdernam, in turn, is a wholly-owned subsidiary  of
'Holderbank'  Financiere  Glaris,  Ltd.  (Holderbank),  a  publicly-traded Swiss
corporation.
 
     Most of Holnam's sources of  financing are supported by Holderbank  letters
of  comfort.  In  view  of Holnam's  current  financial  circumstances, Holnam's
ongoing ability  to  borrow from  these  sources is  dependent  on  Holderbank's
continuance  of such  support and  the lenders'  acceptance of  these letters of
comfort. Without such support, Holnam's  existing sources of financing would  be
in  jeopardy and  its ability  to secure  other sources  of financing  cannot be
assured.
 
     Throughout the  reporting  period,  Holnam  has  held  an  approximate  60%
interest (59% at December 31, 1992) in St. Lawrence Cement, Inc. (St. Lawrence),
a  publicly-traded Canadian  corporation. In addition,  throughout the reporting
period, Holnam has held  interests in Dundee Cement  Company (Dundee) and  Ideal
Basic Industries (Ideal). As of January 1, 1990, Holnam owned 100% of Dundee and
67.4% of Ideal. During 1990 the 32.6% minority interest in Ideal was acquired by
Holnam; Dundee and Ideal were then merged with and into Holnam (see Note 3).
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION
 
     The  consolidated financial statements  include the accounts  of Holnam and
its subsidiaries. All  significant intercompany accounts  and transactions  have
been eliminated.
 
REVENUE RECOGNITION
 
     Revenue  from the sale  of cement and  related products is  recorded at the
time of passage of title, which generally is when the products are shipped.
 
INVENTORIES AND SUPPLIES
 
     Production inventories are valued at the  lower of average cost or  market.
Cost  includes material,  labor and  manufacturing overhead.  Supplies and spare
parts are inventoried when purchased, and  when they are placed in service  they
are charged to expense or capitalized as plant and equipment, as appropriate.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property,   plant  and  equipment  is   stated  at  cost  less  accumulated
depreciation and  depletion. Depreciation  and depletion  is provided  based  on
estimated  service lives using the  straight-line method for financial reporting
purposes. Estimated service lives are as follows:

                                                                                               --------
<S>                                                                                            <C>

</TABLE>
 
     Betterments, renewals and extraordinary repairs that extend the life of the
asset are capitalized;  other repairs  and maintenance costs  are expensed.  The
cost  and accumulated depreciation applicable to assets retired are removed from
the accounts and the gain or loss on disposition recognized in income.
 
     Quarry preparation and reclamation costs are expensed when incurred.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
COST IN EXCESS OF NET ASSETS ACQUIRED
 
     Cost in excess of net assets acquired is amortized on a straight-line basis
over 40 years. As  of December 31, 1992  and 1991, the accumulated  amortization
was approximately $20,000,000 and $ 18,000,000, respectively.
 
INCOME TAXES
 
     Holnam and its U.S. subsidiaries file a consolidated U.S. income tax return
with  other  members of  the  Holdernam group  and  share in  the  resulting tax
liability (or  benefit) in  accordance with  the terms  of an  intercompany  tax
sharing  agreement.  Under the  provisions of  the  tax sharing  agreement, each
member of the Holdernam  group determines its tax  liability (benefit) based  on
the tax it would pay as a separate company (or, in the event of a loss, based on
the  benefit received by the group company for its separate company losses), and
pays or receives payment from Holdernam accordingly.
 
     Provision is  made for  appropriate  taxes on  unremitted earnings  of  St.
Lawrence.
 
     Income  taxes  are provided  based upon  Statement of  Financial Accounting
Standards No. 96, 'Accounting for Income Taxes'. As required, Holnam will  adopt
the   provisions  of  Statement  of  Financial  Accounting  Standards  No.  109,
'Accounting for Income Taxes' in 1993. Adoption of this statement will not  have
a  significant impact on Holnam's consolidated  financial position or results of
operations.
 
NET INCOME (LOSS) PER SHARE
 
     Net income  (loss) per  share for  each of  the respective  years has  been
computed  by dividing net income (loss) by the weighted average number of common
shares outstanding during the year. The weighted average number of common shares
for  1992,  1991  and  1990   was  134,882,927,  134,782,030  and   115,669,884,
respectively.
 
FOREIGN CURRENCY TRANSLATION
 
     For   significant  foreign  operations,  the  local  currencies  have  been
designated as  the functional  currencies; the  assets and  liabilities of  such
foreign  subsidiaries are  translated into U.S.  dollars at  year-end rates, and
income and expenses are translated at average rates for the year. Changes in the
cumulative foreign currency translation adjustment are included in stockholders'
equity. For  certain U.S.  operations of  St. Lawrence  for which  the  Canadian
dollar  has been designated  as the functional  currency, translation losses are
included in  income and  amounted to  $6,211,000, $3,296,000  and $3,429,000  in
1992, 1991 and 1990, respectively.
 
CASH FLOW INFORMATION
 
     For  purposes of  the consolidated statement  of cash  flows all short-term
investments with an original maturity less  than three months are considered  to
be cash equivalents.
 
RECLASSIFICATIONS
 
     Certain  reclassifications have  been made to  the 1991  and 1990 financial
statements to conform to the 1992 presentation.
 
(3) MERGER, ACQUISITIONS AND INVESTMENTS IN UNCONSOLIDATED ENTITIES
 
     In January 1990, Dundee  acquired all of the  outstanding common shares  of
Northwestern  States  Portland  Cement  Company  (Northwestern  States)  for  an
aggregate purchase price of $22.4 million. In
 
                                      F-10

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
addition, Dundee paid approximately $21.9 million of outstanding indebtedness of
Northwestern States.  The total  cash outlay  was approximately  $46.9  million,
including direct costs of the acquisition.
 
     In  March 1990, Ideal shareholders approved  a plan of merger through which
Holnam acquired all of the remaining 32.6% minority interest in Ideal by issuing
one share of Holnam stock for every four shares of Ideal stock held by the Ideal
minority shareholders.  The  total  cost  of the  acquisition  of  the  minority
interest,  including the  value of  the shares  issued (calculated  at $7.50 per
share) and the related costs (approximately $8 million) incurred in  conjunction
with the merger, was $116 million.
 
     In  August 1990,  Holnam acquired all  of the outstanding  common shares of
United Cement Company. The aggregate purchase price was $60.7 million, including
direct costs of the acquisition.
 
     In October 1990, Holnam acquired  the assets of Diversified Materials  Inc.

     These results include adjustments for increased amortization, depreciation,
interest  and income tax expense and elimination of minority equity in net loss,
and are not  necessarily indicative  of what  the actual  results of  operations
would have been had the acquisitions taken place on January 1, 1990.
 
     During 1991, St. Lawrence acquired a 10.8% interest in Philip Environmental
Inc., two ready-mix operations, and a 49% interest in Unilock Inc. Also in 1991,
Holnam  acquired  a  49.98%  interest  in  Cemtech  LP,  a  limited  partnership
specializing in  programs  involving  waste  derived  fuels  and  raw  materials
associated  with  the cement  industry. The  aggregate purchase  prices totaling
$45.0 million have been accounted for  as either cost method investments  ($22.0
million),  equity method  investments ($17.2  million) or  business combinations
accounted for as purchases ($5.8 million), as appropriate. The pro-forma  effect
of  the 1991 business combinations, had they  occurred as of January 1, 1990, on
the consolidated results of operations for the years ended December 31, 1991 and
1990 is not material.
 
     During 1992,  St.  Lawrence  acquired  Beton  Mathers,  an  eastern  Canada
concrete  operation. The acquisition  price was $11.6  million. This acquisition
was funded  with $3.1  million cash  and the  issuance of  $8.5 million  of  St.
Lawrence  preferred stock  that has a  7% cumulative dividend,  callable after 5
years and redeemable  after 5  years and before  10 years.  In addition,  Holnam
purchased  the assets of C-Cure of Florida, Inc., a blender of grouts and cement
products for a price of approximately $1.6 million. The pro-forma effect of  the
1992  business combinations,  had they  occurred as of  January 1,  1991, on the
consolidated results of  operations for the  years ended December  31, 1992  and
1991  is not  material. Also,  St. Lawrence  acquired a  49% interest  in Euclid
Admixture Canada Inc., an admixture company,  for a price of approximately  $1.0
million.

</TABLE>
 
     During   the  fourth  quarter   of  1992,  St.   Lawrence  committed  to  a
restructuring plan to significantly reduce  costs and recorded a pre-tax  charge
of  $11.0 million.  The charge  includes consulting  costs, separation  costs of
employees leaving St. Lawrence, and other restructuring costs.
 
     During the fourth quarter of 1991, Holnam implemented a restructuring  plan
to  reduce  costs  and rationalize  facilities  within its  U.S.  operations. In
connection with this plan,  Holnam recorded a pre-tax  charge of $18.6  million.
The  restructuring charge included future costs under a non-cancellable facility
lease, provisions  for  employee  relocation,  separation  costs  for  employees
leaving  the Company  and reductions (to  net realizable value)  in the carrying
amount of assets related to facilities  that management had concluded should  be
sold or closed.

     At  December 31,  1992 the fair  value of  long-term receivables, estimated
using the expected future cash flows  discounted at interest rates between  4.5%
and 6.0%, approximated $21 million.
 
     The  fair value of St. Lawrence's  investment in Philip Environmental Inc.,
carried at its original cost of  approximately $20.0 million (differs from  1991
U.S.  dollar acquisition costs of  $22.0 million discussed in  Note 3 due to the
strengthening of the U.S. dollar in 1992), approximated $26 million at  December
31, 1992.
 
(8) BOXCROW
 
     In  1989, Holnam acquired an option to  purchase the business and assets of
BoxCrow Cement Company, L.P. (BoxCrow) and a 50% equity interest of $500 in  the
general  partner  of  BoxCrow.  Holnam terminated  its  option  to  purchase the
business and assets of BoxCrow in September, 1991.
 
     During the period of this option, Holnam agreed to provide working  capital
and  management  services.  Under  the  working  capital  agreement,  Holnam was
obligated to provide working  capital loans to BoxCrow,  the repayment of  which
is,  in general, subordinate to other BoxCrow indebtedness. The loans are due by
January 1, 1999  and are interest  bearing. As  of December 31,  1991 and  1990,
Holnam  had  made working  capital  loans of  $30.6  million and  $22.6 million,
respectively, to BoxCrow. In 1992, holders of senior debt and other  obligations
drew  $5.8 million on Holnam-reimbursable letters  of credit. These draws, which
were fully  reserved in  1991, became  additional subordinated  working  capital
loans  to BoxCrow. As such, at December 31, 1992 the total working capital loans
approximate $36.4 million.
 
     Holnam management believes it  is highly unlikely  that BoxCrow will  repay
the  working capital loans. A provision of $38.6 million was recorded in 1991 to
reduce the  carrying  value  of  subordinated working  capital  loans  to  their
estimated  net realizable  value. In August  1992, BoxCrow filed  for Chapter 11
bankruptcy protection.  In  mid-September,  the  bankruptcy  court  appointed  a
trustee  to oversee the business and assets of BoxCrow for an indefinite period.
Holnam's obligations under its management agreement expired in September, 1992.
 
(9) SHORT-TERM NOTES PAYABLE AND LONG-TERM DEBT
 
     At December 31, 1992,  Holnam had $3,000,000  outstanding on a  $13,000,000
short-term  uncommitted credit agreement expiring  in December 1993. Interest is
at LIBOR  plus .6%.  This facility  is  used to  fund Holnam's  working  capital
requirements.  Additionally,  St. Lawrence  has  available, for  working capital
requirements, a series of short-term, uncommitted credit agreements with several
banks aggregating approximately $76.3 million ($97,000,000 Canadian) expiring in
December 1993, none of which was  outstanding at December 31, 1992. Interest  is
at bank prime rate. Outstanding balances are payable on demand.

 (a) The   agreement  contains  various   restrictive  covenants  including  the
     maintenance of  specified ratios  or  amounts of  tangible  capitalization,
     interest   coverage,  debt  to   equity  and  current   assets  to  current
     liabilities, all as defined in the agreement. The agreement also contains a
     subjective acceleration  clause. Additionally,  an  event of  default  will
     occur  if Holderbank and  affiliates cease to own  directly or indirectly a
     majority of  the  issued and  outstanding  shares  of stock  of  Holnam.  A
     facility fee is charged on the total commitment.
 
     The  agreement also governs  the amount of  retained earnings available for
     the payment of dividends. The Company may declare and pay cash dividends on
     its common stock up to a maximum  amount of $15,000,000 in any fiscal  year
     if   the  ratio  of  earnings  before  interest,  taxes,  depreciation  and
     amortization (excluding St.  Lawrence) to interest  expense (excluding  St.
     Lawrence) is 3:00 or greater.
 
 (b) A  two- year period of non-mandatory repayment of principal is provided for
     in the loan agreement and may be renewed each year by mutual consent. After
     this period, the  loan may be  converted into  a term loan  payable over  a
     six-year period.
 
 (c) These  loan agreements contain  various covenants which  in no instance are
     materially more restrictive than those discussed in (a) above.
 
 (d) Industrial Revenue bonds issued by city or county governments or industrial
     developments are  included in  long-term debt.  Holnam is  obligated  under
     related  lease agreements to make payments sufficient to pay interest costs
     of the bonds plus principal payments as they become due.
 
 (e) This debt, provided in 1992 by Holderbank, through Holdernam, is  presently
     non-interest  bearing and matures at the latest of (1) January 1, 1994, (2)
     after written demand, or (3) the  date on which repayment would not  result
     in  a Holnam default of any covenants existing under financing arrangements
     with Holnam's senior  lenders. The obligation  becomes interest bearing  at
     LIBOR  plus 3% when  Holnam's (exclusive of  St. Lawrence) net  income in a
     calendar year equals or exceeds $5,000,000.
 
 (f) In 1991  and  early 1992,  the  Company  entered into  interest  rate  swap
     agreements  with  commercial banks.  Pursuant to  the swap  agreements, the
     Company makes fixed  interest payments.  These agreements  expire when  the
     related debt obligations mature. St. Lawrence makes fixed interest payments
     through  1994 at an effective rate of  8.75% on a notional principal amount
     of $50 million. Holnam and St. Lawrence  are exposed to credit loss in  the
     event  of non-performance  by the other  parties to the  interest rate swap
     agreements but do not anticipate nonperformance by such parties.
 
- ----------------------------------------------------------
     Holderbank has issued  letters of  comfort to certain  of Holnam's  lenders
(Note 1).
 
     Financial  institutions have issued  irrevocable letters of  credit for the
account of  Holnam or  St. Lawrence  in favor  of the  lessors under  a  certain
operating  lease ($25 million; Note 13) holders of industrial revenue bonds ($18
million), and others ($9.5 million). As  of December 31, 1992, these letters  of
credit totaled approximately $52.5 million.
 
     In  addition,  Holnam  guarantees approximately  50%  of the  bank  debt of
Cemtech LP. This  guarantee is for  an amount not  to exceed approximately  $7.5
million,  of which  approximately $2.6 million  was outstanding  at December 31,
1992.  St.  Lawrence  separately  has  issued  guarantees  to  others  totalling
approximately $7.3 million.

</TABLE>
 
     The fair value of  Holnam's long-term, fixed rate  debt (excluding debt  on
which interest rate swap agreements have been entered into) at December 31, 1992
has  been  estimated based  on quoted  market prices  for the  issue, or  on the
current rates  offered to  Holnam for  debt  of the  same or  similar  remaining
maturities.  The carrying amount  of such debt totalled  $197 million, while the
estimated fair value is $221 million.
 
     The fair value of  interest rate swaps, approximately  $17 million, is  the
estimated  amount  that Holnam  would pay  to terminate  the swap  agreements at
December 31, 1992, taking into consideration the current interest rates.

     Deferred income  taxes provided  in the  consolidated financial  statements
relate  to certain  income and  expense items  recorded for  financial reporting
purposes in one period and for tax purposes in another period. Major components,
which are principally related to St. Lawrence, include temporary differences for
excess financial  reporting  over tax  basis  on certain  plant  and  equipment,
depreciation,  depletion and amortization, and gain  on disposition of plant and
equipment.
 
     Holnam has  recognized  the  benefit  of  certain  loss  carryforwards  for
financial  reporting  purposes through  the elimination  of deferred  taxes that
would reverse during the loss carryforward period. At December 31, 1992,  Holnam
had  net operating loss  carryforwards of approximately  $360 million which have
not been  recognized for  financial  reporting purposes,  and are  available  to
offset  future taxable income. They expire  in 1997 through 2007. Utilization of
the operating  loss  carryforwards depends  upon  Holnam's ability  to  generate
future  taxable income,  the Company's ability  to sustain  the ordinary (versus
capital) loss  treatment of  approximately $136  million of  net operating  loss
carryforwards,  as well  as any  issues which  may result  from an  audit by the
Internal Revenue  Service  which  is  currently  in  process.  Holnam  also  has
$4,200,000  of investment tax credit carryforwards which are available to offset
future income taxes payable and expire in 1994 through 2000.
 
(11) PENSION AND CERTAIN OTHER BENEFIT PLANS
 
     Holnam has several noncontributory  defined benefit pension plans  covering
substantially  all employees.  Plan benefits  are generally  based on  length of
service and  average compensation.  It is  Holnam's policy  to fund  actuarially
determined pension costs subject to minimum funding requirements of the Employee
Retirement  Income  Security  Act  of 1974.  Pension  plan  assets  are invested
primarily in equity securities, short-term investments and government bonds.
 
     Total pension  expense  under  these  defined  benefit  plans  amounted  to
$4,797,000,  $5,216,000 and $4,074,000 in 1992, 1991 and 1990, respectively. The
net periodic pension cost of these  plans included the following components  for
the years ended December 31 (in thousands):

     In  addition to providing pension benefits, Holnam provides health care and
life insurance benefits for certain retired  employees. The cost of health  care
benefits is recognized as claims arise. For 1992, 1991 and 1990, the total costs
of all of these benefits aggregated approximately $3.7 million, $4.3 million and
$3.8 million, respectively.
 
     The  Financial Accounting  Standards Board  (FASB) has  issued Statement of
Financial Accounting Standards No. 106 'Employers' Accounting for Postretirement
Benefits  Other  than  Pensions'  which  requires  companies  to  recognize  the
liability  for  postretirement  benefits as  the  benefits are  earned  by their
employees. The unfunded  Accumulated Postretirement Benefit  Obligation and  the
unfunded  Expected Postretirement Benefit Obligation as of January 1, 1993 under
the postretirement medical  and life  insurance benefits  plan approximates  $70
million  and $77 million,  respectively. Effective January  1, 1993, Holnam will
adopt the new  accounting standard, recognizing  the Accumulated  Postretirement
Benefit  Obligation  (the transition  obligation) as  a  cumulative effect  of a
change in accounting principle.  Management estimates that  the adoption of  the
standard  will also increase  postretirement benefit expense  by $2.5 million in
1993.
 
     In 1992, the FASB  issued Statement of  Financial Accounting Standards  No.
112, 'Employers' Accounting for Postemployment Benefits.' This standard requires
employers  to recognize the obligation to provide benefits to former or inactive
employees after employment but before  retirement under certain conditions.  The
obligation  should be  recognized if  it is  attributable to  employees' service
already rendered, the rights  to these benefits accumulate  or vest, payment  of
the benefits is probable and the amount can be reasonably estimated. Holnam must
adopt  the  provisions of  Statement  No. 112  no  later than  January  1, 1994.
Management believes  that  the  adoption  of  this  standard  will  not  have  a
significant  impact on  Holnam's consolidated  financial position  or results of
operations.

(12) RELATED PARTY TRANSACTIONS
 
     As of December  31, 1992  and 1991,  Holnam reflected  accounts payable  of
$582,000 and $ 1,220,000, respectively, to Holderbank and affiliates.
 
     As  of  December 31,  1992 and  1991,  Holderbank subsidiaries  and related
parties are holders of subordinated notes consisting of approximately $4,340,000
in 16% notes due in 1998 and $14,350,000 in 9.6% notes due in 1998. Additionally
in 1992, $50,000,000 of  currently interest free notes,  due at the earliest  in
1994,  was borrowed  from a Holderbank  subsidiary. Interest  expense on related
party debt was  $2,088,000, $2,087,000 and  $2,454,000 in 1992,  1991 and  1990,
respectively.
 
     Holnam  purchased $6,011,000 and $6,279,000 of cement in 1991 and 1990 from
BoxCrow (see Note 8).
 
     Holderbank and  Holnam have  a general  assistance agreement  which,  among
other  things, provides for  the sharing of  research and development, technical
knowledge and certain  facilities. Fees  charged by an  affiliate of  Holderbank
pursuant  to  the general  assistance  agreement for  1992,  1991 and  1990 were
$3,897,000, $4,715,000 and $3,749,000, respectively.
 
     Commissions and expenses of  $385,000, $412,000 and  $883,000 were paid  to
Holderbank and affiliates in 1992, 1991 and 1990, respectively.
 
     As  discussed in Note 9, Holderbank has provided certain comfort letters to
issuers of  letters of  credit  and various  lenders.  Related fees  charged  by
Holderbank  for such letters  were $2,345,000, $2,939,000  and $656,000 in 1992,
1991 and 1990, respectively.

     Holnam  leases  the facilities  and equipment  at  the Tijeras,  New Mexico
cement plant. The lease expires  in 2003 with Holnam  having an option to  renew
the lease for a seven year period and then to either renew the lease or purchase
the  facilities and  equipment at  fair market value  (see also  Note 9). Rental
expense under the  Tijeras lease  was $6,399,000, $6,399,000  and $6,501,000  in
1992, 1991 and 1990, respectively.
 
     Holnam  also leases  certain other  office space,  terminal facilities, and
manufacturing, transportation  and office  equipment  under leases  expiring  on
various  dates  through  2020.  Rental  expense  under  these  other  leases was
$10,711,000, $13,789,000 and $13,342,000 in 1992, 1991 and 1990, respectively.

(14) CONTINGENCIES

defendant in approximately 80 silicosis actions. Ideal (a Holnam predecessor) is
also named as a defendant in several

of these actions. Other filings may occur in the future. In those lawsuits which
specify  damages,  the  individual claims  range  from $600,000  to  $4 million.
Historically, most actions  have been  resolved before  trial with  a number  of
defendants  contributing to each settlement.  To date, the Company's disposition
cost per case has not been material, nor has the aggregate disposition cost  for
all  such  cases.  Although the  ultimate  outcome  of these  matters  cannot be
predicted with certainty, management of Holnam believes, after consultation with
counsel, that the resolution of these  actions will not have a material  adverse
effect on Holnam's consolidated financial position or results of operations.
 
     Under an agreement with the Air Quality Division of the Michigan Department
of  Natural Resources, Holnam conducted testing  in 1991 at its Dundee, Michigan
plant to determine what control devices,  in addition to the baghouse  completed
in  1991, are necessary to achieve satisfactory opacity of the kiln stack plume.
Based on such  testing, Holnam believes  that the use  of gas stream  absorbents
results  in an acceptable opacity level. Holnam has presented the results of the
testing to  the Michigan  Department  of Natural  Resources and  is  negotiating
permit conditions with the Air Quality Division.
 
     There  are  various  other  contingent liabilities  and  pending  legal and
environmental proceedings involving Holnam's  subsidiaries which are  considered
by  management as  incidental to its  ordinary course of  business. Although the
final outcome cannot be predicted  with certainty, management believes that  the
resolution  of these matters will not have a material adverse effect on Holnam's
consolidated financial position or results of operations.
 
(15) EMPLOYEE STOCK PLANS
 
     Two million shares of  common stock have been  reserved for issuance  under
the  Employee  Stock Purchase  Plan (Purchase  Plan).  Under the  Purchase Plan,
eligible employees (generally all fulltime employees of Holnam, excluding  those
employed by St. Lawrence and St. Lawrence subsidiaries) may subscribe for shares
of  common stock  at a  purchase price of  90% of  the closing  market price (as
defined). The Purchase Plan will terminate  when all 2,000,000 shares of  common
stock  reserved  thereunder  shall  have  been  subscribed  for,  unless earlier
terminated by  the Board  of Directors.  In 1990,  54,000 shares  of stock  were
purchased  under  the  Purchase  Plan  for  a  purchase  price  of approximately
$147,000. In 1991, approximately 87,000 shares of stock were purchased under the
Purchase  Plan  for  a  purchase  price  of  approximately  $387,000.  In  1992,
approximately 121,000 shares of stock were purchased under the Purchase Plan for
a purchase price of approximately $347,000.
 
     In  1990, Holnam established the 1990 Stock Option Plan (Stock Option Plan)
for certain fulltime key employees of Holnam. The Stock Option Plan provides for
the grant of options to purchase up  to 2,150,000 shares of Holnam common  stock
at  not less  than the fair  market value  of such stock  at the  date of grant.
Additionally, stock appreciation  rights (SARs)  may be granted  in tandem  with
options.  Also in 1990,  options to purchase  249,531 shares at  $9.50 per share
(all immediately  exercisable) were  issued to  holders of  options to  purchase
Ideal  shares (pursuant to an Ideal plan which  was assumed by Holnam as part of
the merger).
 
     On March 23, 1990,  options to purchase an  aggregate of 473,000 shares  of
Holnam  common stock at an exercise price  of $7.25 per share were granted under
the Stock Option  Plan. The options  become exercisable  at the rate  of 33  1/3
percent  per year on each of the  first three annual anniversaries of their date
of grant, and  such options expire  on March  22, 2000. In  addition, SARs  were
granted in tandem with such options.
 
     ln  1991, options  to purchase an  additional 172,000  shares were granted.
These options become exercisable six months from the date of grant and expire in
2001. In addition, SARs were granted in tandem with such options.
 
     Transactions under the Stock Option Plan are as follows:

(a) Segment  income (loss)  from operations is  defined as  income (loss) before
    income taxes and minority equity in net income (loss) less other income.  In
    1992,  the  United  States and  Canada  segment results  include  charges of
    $1,750, and $9,287, respectively, relating to unusual charges. In 1991,  the
    United States segment results include charges of $61,672 relating to unusual
    charges.
 
     Holnam  sells cement to  various classes of  customers who are  part of the
construction industry, including ready-mix  concrete customers. Other  customers
include  concrete products  manufacturers, building materials  dealers and other
large-scale  users  of   cement.  Although  the   Company's  customer  base   is
geographically  diversified, collection of receivables is partially dependent on
the economics of the  construction activity. There were  no sales to any  single
customer which aggregated in excess of 10% of sales for 1992, 1991 or 1990.

                          HOLNAM INC. AND SUBSIDIARIES
                NOTES TO CONDENSED INTERIM FINANCIAL STATEMENTS
 
(1) GENERAL
 
     The  accompanying financial  statements have  been prepared  by Holnam Inc.
('Holnam') without audit pursuant to the rules and regulations of the Securities
and Exchange Commission. Certain  information and footnote disclosures  normally
included  in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules  and
regulations.  Holnam  believes that  the disclosures  are  adequate to  make the
information  presented  not  misleading  when  read  in  conjunction  with   the
consolidated  financial statements  and the  notes thereto  included in Holnam's
Form 10-K, as amended by Form  10-K/A-1, filed with the Securities and  Exchange
Commission for the year ended December 31, 1992.
 
     The  financial information  presented reflects  all adjustments (consisting
only of normal recurring adjustments) which  are, in the opinion of  management,
necessary for a fair statement of the results for the interim periods presented.
The Company's business is highly seasonal; consequently, the results for interim
periods  should not be considered representative of the expected results for the
full year.
 
     Certain reclassifications  have been  made to  the 1992  financial data  to
conform to the 1993 presentation.
 
(2) ACQUISITIONS
 
     On  May 19,  1993, Holnam  acquired a  75% interest  in a  partnership (the
Partnership) that operates a cement  manufacturing plant located in  Midlothian,
Texas. The purchase price was approximately $90.6 million.
 
     The transaction was financed as follows:

</TABLE>
 
     The Holnam equity contribution was funded via the issuance, to an affiliate
of  Holderbank,  of 600,000  shares  of non-voting,  $50  Cumulative Convertible
Preferred Stock,  dividend  payable  in-kind  at  Holnam's  option,  each  share
convertible  into 13.5 shares  of Holnam common stock,  redeemable after May 15,
1997.
 
     The transaction has been accounted for as a purchase and the purchase price
was allocated,  based upon  preliminary estimates  of fair  value which  may  be

(5) LONG-TERM DEBT
 
     In  conjunction  with  the  acquisition  discussed  in  Note  2,  a  Holnam
subsidiary assumed the obligation for $26.7 million of industrial revenue  bonds
maturing  on December 1, 2009.  A letter of credit  expiring May 1, 1996 permits
the bond trustee to draw amounts to pay principal and accrued interest for up to
65 days on the related bonds. The interest rate applicable to the bonds is based
on a weekly variable rate.
 
     In addition, the  Holnam subsidiary established  a $25.0 million  unsecured
revolving  credit  facility,  which  reduces  by  $5.0  million  per  year until
termination in 1996. Interest on the facility varies with LIBOR.
 
     The obligations of the Holnam subsidiary under the letter of credit and the
revolving credit facility are  guaranteed jointly and  severally by Holnam  Inc.
and its partner in the investment.

(6) CONTINGENCIES
 
     A   Holnam  subsidiary  is   a  defendant  or   third  party  defendant  in
approximately 77 silicosis actions. Ideal (a Holnam predecessor) is also named a
defendant in several of these actions. Other filings may occur in the future. In
those lawsuits which specify damages, the individual claims range from  $600,000
to $4 million. Historically, most actions have been resolved before trial with a
number  of defendants  contributing to each  settlement. To  date, the Company's
disposition cost  per  case  has  not  been  material,  nor  has  the  aggregate
disposition  cost for  all such  cases. Although  the ultimate  outcome of these
matters cannot be predicted with  certainty, management of Holnam believes  that
the  resolution of  these actions  will not  have a  material adverse  effect on
Holnam's consolidated financial position or results of operations.
 
     Under an agreement with the Air Quality Division of the Michigan Department
of Natural Resources, Holnam conducted testing  in 1991 at its Dundee,  Michigan
plant  to determine what control devices,  in addition to the baghouse completed
in 1991, are necessary to achieve satisfactory opacity of the kiln stack  plume.
Based  on such testing,  Holnam believes that  the use of  gas stream absorbents
results in an acceptable opacity level. Holnam has presented the results of  the
testing  to  the Michigan  Department of  Natural  Resources and  is negotiating
permit conditions with the Air Quality Division.
 
     There are  various  other  contingent liabilities  and  pending  legal  and
environmental  proceedings involving  Holnam or Holnam's  subsidiaries which are
considered by  management as  incidental  to its  ordinary course  of  business.
Although  the final outcome  cannot be predicted  with the certainty, management
believes that the resolution of these  matters will not have a material  adverse
effect on Holnam's consolidated financial position or results of operations.
 
(7) CHANGES IN ACCOUNTING PRINCIPLES
 
POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
 
     Effective  January 1, l993, the Company adopted the provisions of Statement
of Financial  Accounting Standards  (SFAS) No.  106 'Employees'  Accounting  for
Postretirement  Benefits  Other  than  Pensions',  which  requires  companies to
recognize the liability for postretirement benefits as they are earned by  their
employees  (other than employees  of St. Lawrence).  Holnam provides health care
and life insurance benefits for  substantially all current and former  employees
who  retired from active service and  their dependents. Benefits are extended to
dependents of deceased retirees for one year following the death of the retiree.
Employees retiring prior to January 1, l996 will receive benefits in  accordance
with  various individual  plan agreements.  Employees retiring  after January 1,
l996 will receive a fixed dollar subsidy that can be used to purchase one of the
three retiree medical plans, with differences between the subsidy amount and the
total cost of  coverage being  paid by  the retiree.  The health  care and  life
insurance  benefit plans are unfunded. In  adopting SFAS No. 106, Holnam elected
to immediately  recognize, as  of  January 1,  l993, the  unfunded,  Accumulated
Postretirement  Benefit Obligation  (the Transition  Obligation) of approximated
$67.0 million ($64.0  million net of  applicable income taxes)  as a  cumulative
effect  of a change in accounting principle. The Expected Postretirement Benefit
Obligation as of  January 1, l993  approximated $71.0 million.  The adoption  of
this   standard  will   result  in   1993  postretirement   benefit  expense  of
approximately $5.5 million, an increase  of approximately $2.0 million over  the
estimated  1993 cash  costs. The Transition  Obligation, Expected Postretirement
Benefit Obligation and the l993  postretirement benefit expense all differ  from
the Company's previously disclosed estimates as a result of finalizing actuarial
calculations.
 
     The actuarial assumptions used are as follows:

ACCOUNTING FOR INCOME TAXES
 
     Effective January  1, l993,  Holnam  adopted the  provisions of  SFAS  109,
'Accounting  for Income Taxes.'  SFAS 109 replaced  SFAS 96, of  the same title,
which Holnam previously used to account for income taxes. The effect of adopting
SFAS 109 was to recognize a deferred tax liability of $1.7 million that was  not
recognized under SFAS 96. In addition, Holnam determined that approximately $160
million  of tax benefits did  not satisfy the recognition  criteria set forth in
the standard.  Accordingly,  a  valuation allowance  was  recorded  against  the
deferred tax asset.
 
     A valuation allowance is provided when it is more likely then not that some
portion of the deferred tax asset will not be realized. Holnam has established a
valuation  allowance for the full amount  of operating loss carry forwards which
are not anticipated to offset existing net taxable temporary differences. Future
utilization of operating loss carryforwards currently fully reserved will depend
on Holnam's ability to generate future taxable income, the Company's ability  to
sustain  the  ordinary (versus  capital)  loss treatment  of  approximately $136
million of net operating  loss carryforwards, as well  as the resolution of  any
issues which may result from an audit by the Internal Revenue Service.
 
(8) SUBSEQUENT EVENT
 
     On  November 8, 1993,  the Company announced  the calling of  all its $15.3
million 9.25% sinking-fund debentures  outstanding, due in 2000,  at a price  of
$1,009.30  per $1,000.00 principal amount, plus accrued interest. The redemption
will occur in December, 1993.

                             THE STATE OF DELAWARE)
 
     The undersigned hereby certify that:
 
     (1)  Holnam Inc. ('Holnam')  was incorporated on  the 8th day  of May, 1981
under the name HOFI North America  Inc. pursuant to the General Corporation  Law
of the State of Delaware.
 
     (2)  Holcem Inc., a  corporation incorporated on the  23rd day of December,
1993  pursuant  to  the  General  Corporation  Law  of  the  State  of  Delaware
('Holcem'),  owns more than 90%  of the issued and  outstanding shares of common
stock, par  value  $.01  per  share,  of Holnam  and  100%  of  the  issued  and
outstanding  shares of 7% Cumulative Convertible Preferred Stock, par value $.10
per share, of Holnam, which constitute  all the outstanding classes of stock  of
Holnam.
 
     (3)  The directors of Holcem, at a  meeting duly called and held on January
7, 1994, unanimously adopted the following resolutions authorizing the merger of
Holcem with and  into Holnam (the  'Merger') and the  amendment of the  Restated
Certificate of Incorporation, as amended, of Holnam:
 
MERGER OF HOLCEM WITH HOLNAM
 
     RESOLVED,  that, pursuant to Section 253  of the General Corporation Law of
the State of Delaware  (the 'DGCL'), Holcem merge  (the 'Merger') with and  into
Holnam Inc., a Delaware corporation ('Holnam').
 
     RESOLVED,  that at the effective time  of the Merger each outstanding share
of common stock of Holnam (other than any shares owned by Holcem and subject  to
the  rights of  stockholders of Holnam  who perfect  their dissenters' appraisal
rights) be  converted  into  the right  to  receive  $7.65 in  cash  (the  'Cash
Consideration') upon the surrender of the certificates for such shares of common
stock of Holnam to the paying agent for Holdernam Inc.
 
     RESOLVED,  that this  Board of Directors  has reviewed  and considered such
information from and related  to Holnam and concerning  the Merger as it  deemed
relevant  and  appropriate, and  a presentation  by and  the opinion  of Merrill
Lynch, Pierce, Fenner & Smith, dated January 7, 1994 and addressed to Holcem and
certain affiliates of Holcem, concerning the fairness of the Cash  Consideration
to be received by the stockholders of Holnam other than Holcem and, on the basis
of such review and consideration, this Board of Directors finds the Merger to be
fair to the stockholders of Holnam other than Holcem.
 
     RESOLVED, that upon the surrender by Holdernam Inc., a Delaware corporation
and  the  owner  of all  the  issued  and outstanding  capital  stock  of Holcem
('Holdernam'), of the certificates for the  shares of common stock of Holcem  to
the paying agent after the effective time of the Merger, Holnam shall deliver or
cause  to be delivered to Holdernam certificates  for (a) 1,000 shares of common
stock of Holnam in lieu of the 128,491,701 shares of common stock of Holnam held
by Holcem  prior to  the Merger,  and (b)  1,034.71333 shares  of 7%  Cumulative
Convertible  Preferred Stock of Holnam  in lieu of the  620,828 shares of the 7%
Cumulative Convertible Preferred  Stock of Holnam  held by Holcem  prior to  the
Merger,  which  newly issued  certificates shall  represent  all the  issued and
outstanding equity securities of Holnam immediately after the Merger.
 
     RESOLVED, that  the stockholders  of Holnam  other than  Holcem shall  have
appraisal rights as set forth in Section 262 of the DGCL.
 
<PAGE>
     RESOLVED,  that the  proper officers of  Holcem are  authorized to execute,
acknowledge, file and record a certificate of ownership and merger in accordance
with the requirements of Section 253 of the DGCL (the 'Certificate of  Ownership
and  Merger') and to cause  the Merger to become  effective, all without further
action by this Board of Directors.
 
     RESOLVED, that at any time before  the Certificate of Ownership and  Merger
is  filed with the  Secretary of State of  the State of  Delaware, this Board of
Directors may amend these resolutions and abandon the Merger, all in the  manner
and to the extent permitted by Sections 253(c) and 251(d) of the DGCL.
 
AMENDMENT OF THE RESTATED CERTIFICATE OF INCORPORATION OF HOLNAM
 
     RESOLVED,   that  upon  the  effectiveness  of  the  Merger,  the  restated
certificate of incorporation, as amended, of Holnam be amended as follows:

     The  following projections were not prepared  with a view toward compliance
with published  guidelines  of  the  Commission or  the  American  Institute  of
Certified  Public Accountants  regarding projections and  forecasts or generally
accepted  accounting   principles.   Because   of  the  inherent uncertainty of
projections  and  forecasts for such lengthy periods, no assurances can be given
that such projections accurately determine current values or future performance,
which may be significantly more or less favorable than as set forth below.

                                  Holnam Inc.
 
Gentlemen:
 
     We  understand  that the  Board of  Directors and  the sole  stockholder of
Holcem Inc. ('Holcem'),  which is  the holder  of more  than 90%  of the  common
stock, par value $.01 per share (the 'Common Stock'), and all of the 7% Series A
Convertible  Preferred Stock, par value $.10  per share (the 'Preferred Stock'),
of Holnam,  Inc.  (the  'Company'),  intend to  take  certain  corporate  action
pursuant  to Section 253 of the Delaware  General Corporation Law as a result of
which Holcem  will be  merged (the  'Merger')  with and  into the  Company,  the
Company  will become a  wholly-owned subsidiary of  Holdernam Inc. ('Holdernam')
and an indirect wholly-owned subsidiary of 'Holderbank' Financiere Glaris,  Ltd.
('Holderbank'),  and each outstanding share of Common Stock held by shareholders
other  than  the  Company,  Holcem  or  any  of  its  affiliates  (the   'Public
Shareholders')  will be converted  into the right  to receive $7.65  in cash per
share from Holdernam, subject  to the rights of  shareholders who perfect  their
dissenters'  appraisal rights. We understand the  Merger will be effected by the
filing of a  Certificate of Ownership  and Merger (the  'Certificate') with  the
Secretary of State of the State of Delaware, which filing is expected to be made
on or about February 10, 1994.
 
     You  have asked us for  our opinion as to whether  or not the proposed cash
consideration to be received by the  Public Shareholders pursuant to the  Merger
is fair to such shareholders from a financial point of view.
 
     In arriving at the opinion set forth below, we have, among other things:
 
          (1)  reviewed  the Company's  annual reports  to shareholders  for the
     three fiscal years ended, and  its annual report on  Form 10-K for the  two
     fiscal  years ended,  December 31, 1992  and the  related audited financial
     information  included  therein,  and  the  Company's  unaudited   financial
     information  and related  Forms 10-Q for  the three-,  six-, and nine-month
     periods ended March 31, June 30, and September 30, 1993, respectively;
 
          (2) reviewed the  annual reports to  shareholders and related  audited
     financial  information  of St.  Lawrence Cement,  Inc. ('St.  Lawrence'), a
     corporation organized  under the  law of  the Province  of Quebec,  Canada,
     whose  securities are  publicly traded  on the  Montreal and  Toronto stock
 
<PAGE>
     exchanges, and of which the Company owns shares representing  approximately
     59%  of the  equity interest  and 77%  of the  voting rights  for the three
     fiscal years ended December 31, 1992;
 
          (3) reviewed  certain  information, including  financial  projections,
     relating  to the businesses,  earnings, cash flow,  assets and prospects of
     the Company, based upon information furnished to us by the Company, and  of
     St. Lawrence, furnished to us by St. Lawrence;
 
          (4)  conducted discussions  with members  of senior  management of the
     Company  and  St.  Lawrence  concerning  their  respective  businesses  and
     prospects,  and conducted discussions with  members of senior management of
     Holderbank concerning such businesses and prospects;
 
          (5) reviewed the Registration  Statement on Form  S-4 of the  Company,
     including  the combined Proxy  Statement and Prospectus  dated February 14,
     1990 included therein,  filed with the  Securities and Exchange  Commission
     ('SEC')  in  connection with  the  merger of  the  Company and  Ideal Basic
     Industries, Inc.;
 
          (6) reviewed  the current  and historical  market prices  and  trading
     activity  for  the Common  Stock  and compared  them  with that  of certain
     publicly traded companies which we deemed  to be reasonably similar to  the
     Company, in whole or in part;
 
          (7)  reviewed  the current  and historical  market prices  and trading
     activity for the Class A subordinate shares of St. Lawrence;
 
          (8) compared the results  of operations of the  Company with those  of
     certain  companies which we deemed to be reasonably similar to the Company,
     in whole or in part;
 
          (9) reviewed a draft dated January 6, 1994 of the Certificate;
 
          (10) reviewed the Certificate of Designation relating to the Preferred
     Stock;
 
          (11) reviewed  a  draft  dated  January 7,  1994  of  the  Rule  13e-3
     Transaction Statement, including the Disclosure Statement included therein,
     proposed  to  be filed  with the  SEC  in connection  with the  Merger; and

          (12) compared the financial terms  of the transactions contemplated by
     the  Certificate  with  the  financial  terms  of  certain  other  business
     combinations and other transactions which we deemed to be relevant.
 
     We  have  also  reviewed such  other  financial studies  and  analyses, and
performed such other investigation and taken into account such other matters  as
we deemed necessary.
 
     In  preparing our opinion  we have relied  without independent verification
upon the accuracy, completeness and fair presentation of all financial and other
information provided  to  us  by  Holderbank,  the  Company  and  St.  Lawrence,
including  information concerning certain tax  matters relevant to our analysis,
or which was publicly  available. In addition, we  have not made an  independent
appraisal  of any of the assets or liabilities of the Company or St. Lawrence or
of the shares of St. Lawrence. With respect to the financial forecasts  referred
to  above, we  have assumed  that they  have been  reasonably prepared  on bases
reflecting  the  best  currently  available  estimates  and  judgments  of   the
management  of the Company or St. Lawrence, as the case may be, as to the future
financial performance of the Company  or St. Lawrence, as  the case may be,  and
that  management of Holderbank concur in those estimates and judgments. In light
of the fact  that Holcem  owns in  excess of  90% of  the Common  Stock and  has
indicated  that  it will  not  sell such  shares of  Common  Stock, we  were not
requested to, and did not, solicit  indications of interest for the  acquisition
of all or part of the Common Stock.
 
     We  have  provided  investment  banking  services  to  Holderbank  and  its
subsidiaries in the  past, other than  the Company, for  which we have  received
compensation.
 
     On  the basis of, and subject to the  foregoing, we are of the opinion that
the cash consideration to be received by the Public Shareholders pursuant to the
Merger is fair to such shareholders from a financial point of view.
 
                                          Very truly yours,
 
                                          MERRILL LYNCH, PIERCE, FENNER &

SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW
 
     262  APPRAISAL RIGHTS. (a)  Any stockholder of a  corporation of this State
who holds shares  of stock on  the date of  the making of  a demand pursuant  to
subsection  (d) of  this section with  respect to such  shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d)  of this section and who has  neither
voted  in favor of the merger or  consolidation nor consented thereto in writing
pursuant to 228 of this title shall be entitled to an appraisal by the Court  of
Chancery  of  the fair  value of  his  shares of  stock under  the circumstances
described in subsections (b) and (c) of  this section. As used in this  section,
the  word 'stockholder' means a holder of record of stock in a stock corporation
and also a member  of record of  a nonstock corporation;  the words 'stock'  and
'share'  mean  and include  what is  ordinarily  meant by  those words  and also
membership or membership interest of a member of a nonstock corporation.
 
     (b) Appraisal rights  shall be  available for the  shares of  any class  or
series  of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to 251, 252, 254, 257, 258, 263 or 264 of this title:
 
     (1) Provided, however, that no appraisal rights under this section shall be
available for the shares of  any class or series of  stock which, at the  record
date  fixed to determine the  stockholders entitled to receive  notice of and to
vote at the  meeting of  stockholders to  act upon  the agreement  of merger  or
consolidation,  were  either (i)  listed on  a  national securities  exchange or
designated as  a national  market system  security on  an interdealer  quotation
system  by the National Association of Securities  Dealers, Inc. or (ii) held of
record by more than 2,000 stockholders;  and further provided that no  appraisal
rights shall be available for any shares of stock of the constituent corporation
surviving  a merger if the  merger did not require for  its approval the vote of
the stockholders of the surviving corporation  as provided in subsection (f)  of
[^251 of this title.
 
     (2)  Notwithstanding  paragraph (1)  of  this subsection,  appraisal rights
under this section shall be available for  the shares of any class or series  of
stock  of a constituent corporation  if the holders thereof  are required by the
terms of an agreement of merger or consolidation pursuant to 251, 252, 254, 257,
258, 263 and 264 of this title to accept for such stock anything except:
 
          a. Shares of stock of the corporation surviving or resulting from such
     merger or consolidation;
 
          b. Shares of  stock of any  other corporation which  at the  effective
     date  of the merger  or consolidation will  be either listed  on a national
     securities exchange or designated as  a national market system security  on
     an  interdealer quotation system by  the National Association of Securities
     Dealers, Inc. or held of record by more than 2,000 stockholders;
 
          c. Cash in lieu of fractional shares of the corporations described  in
     the foregoing subparagraphs a. and b. of this paragraph; or
 
          d.  Any  combination  of the  shares  of  stock and  cash  in  lieu of
     fractional shares described in the foregoing subparagraphs a., b. and c. of
     this paragraph.
 
     (3) In the  event all  of the stock  of a  subsidiary Delaware  corporation
party  to a merger effected under  253 of this title is  not owned by the parent
corporation immediately prior to the merger, appraisal rights shall be available
for the shares of the subsidiary Delaware corporation.
 
     (c) Any corporation may  provide in its  certificate of incorporation  that
appraisal  rights under this  section shall be  available for the  shares of any
class or series of its stock as a  result of an amendment to its certificate  of
incorporation,  any  merger  or  consolidation in  which  the  corporation  is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a  provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
     (1)  If a proposed  merger or consolidation for  which appraisal rights are
provided under this  section is to  be submitted  for approval at  a meeting  of
stockholders, the corporation, not less than 20 days prior to the meeting, shall
notify each of its stockholders who was such on the record date for such meeting
with  respect to  shares for  which appraisal  rights are  available pursuant to
subsections (b) or (c) hereof that appraisal rights are available for any or all
of the shares of the constituent corporations, and shall
 
<PAGE>
include in such  notice a  copy of this  section. Each  stockholder electing  to
demand  the appraisal of his shares shall deliver to the corporation, before the
taking of  the  vote  on the  merger  or  consolidation, a  written  demand  for
appraisal of his shares. Such demand will be sufficient if it reasonably informs
the  corporation of  the identity  of the  stockholder and  that the stockholder
intends thereby to demand the appraisal of  his shares. A proxy or vote  against
the  merger or consolidation  shall not constitute such  a demand. A stockholder
electing to take such action must do  so by a separate written demand as  herein
provided.   Within  10  days  after  the   effective  date  of  such  merger  or
consolidation,  the  surviving  or  resulting  corporation  shall  notify   each
stockholder   of  each  constituent  corporation  who  has  complied  with  this
subsection and  has  not  voted in  favor  of  or consented  to  the  merger  or
consolidation of the date that the merger or consolidation has become effective;
or
 
     (2) If the merger or consolidation was approved pursuant to SS228 or 253 of
this  title, the surviving or resulting corporation, either before the effective
date of the merger or consolidation  or within 10 days thereafter, shall  notify
each  of the stockholders entitled to appraisal  rights of the effective date of
the merger or consolidation and that  appraisal rights are available for any  or
all  of the  shares of  the constituent corporation,  and shall  include in such
notice a  copy  of this  section.  The notice  shall  be sent  by  certified  or
registered  mail, return receipt requested, addressed  to the stockholder at his
address as  it  appears on  the  records  of the  corporation.  Any  stockholder
entitled  to appraisal rights may,  within 20 days after  the date of mailing of
the notice, demand in  writing from the surviving  or resulting corporation  the
appraisal of his shares. Such demand will be sufficient if it reasonably informs
the  corporation of  the identity  of the  stockholder and  that the stockholder
intends thereby to demand the appraisal of his shares.
 
     (e)  Within  120  days   after  the  effective  date   of  the  merger   or
consolidation, the surviving or resulting corporation or any stockholder who has
complied  with subsection (a)  and (d) hereof  and who is  otherwise entitled to
appraisal rights,  may file  a petition  in the  Court of  Chancery demanding  a
determination   of  the   value  of   the  stock   of  all   such  stockholders.
Notwithstanding the foregoing, at  any time within 60  days after the  effective
date  of the merger  or consolidation, any  stockholder shall have  the right to
withdraw his  demand for  appraisal and  to accept  the terms  offered upon  the
merger  or consolidation. Within 120 days after the effective date of the merger
or consolidation,  any stockholder  who has  complied with  the requirements  of
subsections  (a)  and (d)  hereof, upon  written request,  shall be  entitled to
receive from  the  corporation  surviving  the  merger  or  resulting  from  the
consolidation a statement setting forth the aggregate number of shares not voted
in  favor of the merger  or consolidation and with  respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed  to the stockholder within 10 days  after
his  written  request for  such  a statement  is  received by  the  surviving or
resulting corporation  or within  10 days  after expiration  of the  period  for
delivery  of demands  for appraisal  under subsection  (d) hereof,  whichever is
later.
 
     (f) Upon the filing  of any such  petition by a  stockholder, service of  a
copy  thereof shall be  made upon the surviving  or resulting corporation, which
shall within 20 days after  such service file in the  office of the Register  in
Chancery  in which the  petition was filed  a duly verified  list containing the
names and addresses  of all  stockholders who  have demanded  payment for  their
shares  and with whom agreements  as to the value of  their shares have not been
reached by the  surviving or  resulting corporation.  If the  petition shall  be
filed  by  the  surviving  or  resulting  corporation,  the  petition  shall  be
accompanied by  such a  duly verified  list.  The Register  in Chancery,  if  so
ordered  by the  Court, shall give  notice of the  time and place  fixed for the
hearing of such  petition by registered  or certified mail  to the surviving  or
resulting corporation and to the stockholders shown on the list at the addresses
therein  stated. Such notice  shall also be  given by 1  or more publications at
least 1  week  before  the  day  of the  hearing,  in  a  newspaper  of  general
circulation published in the City of Wilmington, Delaware or such publication as
the  Court deems advisable. The forms of  the notices by mail and by publication
shall be approved  by the Court,  and the costs  thereof shall be  borne by  the
surviving or resulting corporation.
 
     (g)  At  the  hearing  on  such petition,  the  Court  shall  determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court  may require the stockholders  who have demanded  an
appraisal  for their  shares and who  hold stock represented  by certificates to
submit their certificates  of stock  to the  Register in  Chancery for  notation
thereon  of the  pendency of the  appraisal proceedings; and  if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the  Court
shall appraise the shares, determining their fair value exclusive of any element
of  value  arising  from the  accomplishment  or  expectation of  the  merger or
consolidation, together with a fair  rate of interest, if  any, to be paid  upon
the  amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate  of
interest  which the surviving or resulting corporation  would have had to pay to
borrow money during  the pendency  of the  proceeding. Upon  application by  the
surviving or resulting corporation or by any stockholder entitled to participate
in  the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal  prior
to  the final  determination of  the stockholder  entitled to  an appraisal. Any
stockholder whose name appears on the  list filed by the surviving or  resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates  of stock  to the  Register in Chancery,  if such  is required, may
participate fully in all proceedings until  it is finally determined that he  is
not entitled to appraisal rights under this section.
 
     (i)  The Court shall  direct the payment  of the fair  value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the  Court
may  direct. Payment shall be  so made to each such  stockholder, in the case of
holders of uncertificated stock forthwith, and the case of the holders of shares
represented by  certificates  upon  the  surrender to  the  corporation  of  the
certificates  representing such  stock. The  Court's decree  may be  enforced as
other decrees in the Court of  Chancery may be enforced, whether such  surviving
or resulting corporation be a corporation of this State or of any state.
 
     (j)  The costs of the  proceeding may be determined  by the Court and taxed
upon the  parties  as the  Court  deems  equitable in  the  circumstances.  Upon
application  of  a stockholder,  the Court  may order  all or  a portion  of the
expenses  incurred  by  any  stockholder   in  connection  with  the   appraisal
proceeding,  including, without  limitation, reasonable attorney's  fees and the
fees and expenses of experts,  to be charged pro rata  against the value of  all
the shares entitled to an appraisal.
 
     (k)  From and after the  effective date of the  merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection  (d)
of  this section  shall be  entitled to vote  such stock  for any  purpose or to
receive payment  of  dividends  or  other distributions  on  the  stock  (except
dividends  or other  distributions payable to  stockholders of record  at a date
which is prior to the effective date of the merger or consolidation);  provided,
however,  that if no  petition for an  appraisal shall be  filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within  60
days  after the  effective date  of the merger  or consolidation  as provided in
subsection (e) of this  section or thereafter with  the written approval of  the
corporation,  then the  right of such  stockholder to an  appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of  Chancery
shall  be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.
 
     (l) The  shares of  the surviving  or resulting  corporation to  which  the
shares  of  such  objecting  stockholders would  have  been  converted  had they
assented to the merger or consolidation shall have the status of authorized  and
unissued shares of the surviving or resulting corporation.
