Item 2.   Acquisition or Disposition of Assets.

          Effective  August 1,  1994 (the  "Closing"),  the Registrant  acquired
substantially all  of the  assets and  assumed most  of the  liabilities of  the
refractory  operations  of  General  Refractories  Company  and  its  affiliated
companies (collectively  referred to as  "General").   These operations  include
nine plants in the United States, a plant near Toronto, Canada and a 49%  equity
interest in two Colombian refractories companies.

          In  addition  to   the  assumption  of  designated   liabilities,  the
Registrant paid General at Closing the $23,450,000  purchase price in cash.  The
purchase price had  been agreed upon by  the Registrant and General  after arm's
length negotiations.    The  purchase  price  was funded  by  the  borrowing  of
$25,000,000 from a  group of institutional lenders on July 29,  1994.  The notes
are unsecured  and have a  fixed interest rate  of 8.55%  per annum, with  semi-
annual  interest  payments  commencing  January  29,  1995.    Annual  principal
repayments  will  commence  July  29,  1996 and  continue,  in  accordance  with
amortization schedules attached to each note, through July 29, 2001.

          The acquisition  adds General's  basic and  silica refractory  product
lines  to   the  Registrant's  existing  refractory  products  and  expands  the
Registrant's sales  opportunities in  the steel,  non-ferrous and  international
markets.  The  Registrant intends to continue to  manufacture General's existing
products.

Item 7.   Financial Statements and Exhibits.

          (a)  Financial  Statements.  No  financial statements of  the acquired
business  of General  have been  provided as  the U.S. refractory  operations of
General have not been combined for financial reporting purposes for at least the
three most recently completed fiscal years and are not capable of  being audited
for the  most recently completed  fiscal year.   The  Registrant has  determined
after analyzing the financial books and records of the refractory operations  of
General that  there could be no  assurance that such  financial statements would
accurately reflect the financial condition, results of operations, cash flows or
changes in stockholder's equity for General's refractory operations.

          (b)  Pro Forma Financial  Information.  The Registrant  has determined
that it cannot  present accurate pro forma financial  information reflecting the
acquisition of General's refractory operations for the same reasons as set forth
in Item 7(a) hereof.

          (c)  Exhibits.  The following exhibits have been filed as part of this
report:

          2.1  Asset  Acquisition Agreement  dated July  11,  1994 by  and among
General Refractories  Company and certain  of its affiliates and  the Registrant
and certain of its affiliates.

          10.1 Note Purchase  Agreement dated July  28, 1994 by and  between the
Registrant and certain of its subsidiaries and the purchasers of the Notes.

inconsistent with such allocation as may be agreed to by Buyers and Sellers.

but excluding  those liabilities for  Known Environmental Matters for  fines and
penalties, if any, assessed against Sellers for actions or inactions  of Sellers

action with respect to such Known Environmental Matters within a reasonable time
after Closing ("Known Environmental Matters Fines and Penalties"):

     result of closing the transactions under this Agreement;

               (3)  any  liabilities relating to:  (A) Environmental Matters (as
     that  term  is  defined  in Section  3.12(d)  hereof)  that  are  not Known

     Penalties;

               (4)  any liabilities or  rights of Sellers under or pertaining to
     any lawsuits in which any Seller is a party;

               (5)  any  liabilities of Sellers relating to the Excluded Assets;
     and

               (6)  the  liabilities  and   obligations  of  Sellers,  if   any,
     identified on Schedule 2.1(b) annexed hereto.

               (c)  Buyers  agree to indemnify, defend and hold harmless Sellers
from and against  any and all  claims, liabilities, damages, suits,  actions and
causes of action of whatsoever nature or character (the "Claims" herein) arising
out of, connected  with, or in any  way related to  all liabilities relating  to
Known Environmental  Matters other  than Known  Environmental Matters  Fines and
Penalties.   Sellers and Buyers have agreed to a reduction in the purchase price
of  $2,700,000 as  a  result of  these  Known  Environmental Matters.    Buyers'
indemnification to Sellers  set forth above is explicitly  limited to the extent
that Sellers  have insurance coverage  for any such Known  Environmental Matters
and that Sellers, in  their sole discretion, determine to use  such coverage for
these Known  Environmental Matters and  that Sellers actually  receive insurance
coverage and proceeds therefor.

               Sellers may, at their sole  discretion but without any obligation
to do so,  tender to one  or more  of their insurance  carriers Claims that  are
presented to Sellers by Buyers or by any other party or governmental agency, and
pursue, maintain or compromise any such claims for insurance coverage.  Once the
amount of insurance proceeds  paid to satisfy all or any part  of such Claims so
tendered  shall  aggregate  $1,000,000,  Sellers  must continue  to  tender  all
succeeding  Claims until  the aggregate  amount  of insurance  proceeds paid  to
satisfy all  or any part of such Claims equals  $3,700,000, at which time Buyers
will cease presenting any Claim or Claims  to Sellers and will indemnify, defend
and hold harmless Sellers from  any and all Claims  that were satisfied only  in
part or not at  all by payment of insurance proceeds.   Nothing herein contained
shall be  or be deemed to  be a representation  or warranty by Sellers  that any
Claims or  Claims so  tendered  will be  accepted for  coverage or  paid by  any
insurance carrier of Sellers.

               In  the event  Sellers determine  to  submit any  such claims  as
provided above, it is agreed that:

               1.   The first $2,700,000  of any net recoveries  received of any
                    insurance proceeds shall be paid to or  retained by Sellers;
                    and

               2.   For insurance  proceeds in excess  of $2,700,000 of  any net
                    recoveries received and  up to a total of  $3,700,000 of any
                    net recoveries received,  such proceeds will be  retained by
                    or be paid to Buyers.

                                       -7-

<PAGE>

               All  insurance proceeds that are received from Sellers' insurance
carriers pursuant to tenders made by Sellers as herein provided shall be applied
to pay,  or in  reimbursement of  payment  for, Claims  for Known  Environmental
Matters.

               All obligations or payments that  are incurred or made by Sellers
for, as a result of, or in  connection with the collection of insurance proceeds
as provided  herein, including, without  limitation, fees and costs  incurred in
pursuing  recovery  of  insurance  policy  proceeds,  deductibles,  self-insured
retentions,  retrospective   premiums  and  all   noncovered  or   uncollectible
underlying limits requirements  by reason  of insurer  insolvency or  otherwise,
shall be deducted from any recoveries.

               Buyers agree to provide Sellers  with notice of all amounts spent
with respect  to the  Known Environmental Matters,  as well as  all information,
data, access  to employees, and other  related matters necessary for  Sellers to
substantiate and prosecute any claims for insurance coverage.

               Nothing herein contained,  including, without limitation, Buyers'
obligation to indemnify, defend and  hold harmless Sellers with regard  to Known
Environmental Matters, shall be or deemed to be a waiver by Sellers of any right
to insurance coverage under and pursuant to any insurance policy for any and all
Claims that may be asserted against Sellers with  respect to Known Environmental
Matters.

     executed and delivered to  Sellers by or on behalf  of Buyers under  or
     pursuant to this Agreement or the transactions contemplated herein;

               (ii) any  and all loss,  liability, cost, expense  or damage
     (including  judgments  and  settlement   payments)  incurred  by   them
     incident to,  arising in connection  with or  resulting from all  other
     liabilities and  obligations directly  or  indirectly  arising from  or
     relating to  (1) acts or  failures to  act by the Buyers  subsequent to
     the Closing,  including Buyer's  possession, use  and operation  of the
     Assets and  the Business  after Closing,  and (2)  all  of the  Assumed
     Liabilities; and

               (iii)     any and all  costs, expenses and all  other actual
     damages incurred  by Sellers in  claiming, contesting  or remedying any
     breach,  misrepresentation,  nonperformance  or  inaccuracy   described
     above,  or  in  enforcing  their  right  of  indemnification hereunder,
     including, by  way of illustration  and not  limitation, all legal  and
     accounting fees, other professional  expenses and all  filing fees, and
     collection  costs  incident  thereto  and  all  such  fees,  costs  and
     expenses   incurred   in  defending   claims  which,   if  successfully
     prosecuted would have resulted in Damages (as defined herein).

               (c)  Damages.  Any  and all of  the items  set forth in  Sections
12.1(a) and 12.1(b)  for which a party  is entitled to be  indemnified hereunder
are called "Damages."

          12.2 Notice of, and Procedures for, Collecting Indemnification.

               (a)  Initial  Claim Notice.   When  a  party becomes  aware of  a
situation which  may result  in Damages  for which  it would  be entitled  to be
indemnified  hereunder, such  party  (the "Indemnitee")  shall submit  a written
notice   (the  "Initial   Claim  Notice")   to  the   other  party   from  which
indemnification  may be forthcoming pursuant  to Section 12.1 (the "Indemnitor")
to such effect with reasonable promptness  after it first becomes aware of  such
matter and  shall  furnish  the  Indemnitor with  such  information  as  it  has
available demonstrating its right  or possible right  to receive indemnity.   If
the potential claim is predicated on, or later results in, the filing by a third
party of any action at law or in equity (a "Third Party Claim"), the Indemnitee 

                                      -40-

<PAGE>

shall provide the Indemnitor with a  supplemental Initial Claim Notice not later
than ten  (10) days prior  to the date  on which  a responsive pleading  must be
filed, and shall also furnish a  copy of such claim (if made in  writing) and of
all  documents received  from the  third party  in  support of  such claim.   In
addition, each  Initial Claim  Notice  shall name,  when  known, the  person  or
persons making  the assertions which are the  basis for such claim.   Failure by
the Indemnitee to  deliver an Initial  Claim Notice  or an update  thereof in  a
timely manner shall not  relieve the Indemnitor of any of  its obligations under
this  Agreement  except to  the  extent that  actual  monetary prejudice  to the
Indemnitor can be demonstrated.

               (b)  Rights of  Indemnitor.   If, prior to  the expiration  of 30
days from the  mailing of an Initial  Claim Notice (the "Claim  Answer Period"),
the Indemnitor shall  request in writing that  such claim not be  paid, the same
shall not be  paid, and the Indemnitor  shall settle, compromise or  litigate in
good faith such claim,  and employ attorneys of  its choice to do so;  provided,
however, that Indemnitee shall not be required  to refrain from paying any claim
which has matured  by court judgment or decree, unless appeal is taken therefrom
and proper  appeal bond posted  by the Indemnitor, nor  shall it be  required to
refrain from paying any claim where such  action would result in the foreclosure
of  a lien upon  any of its  assets or  a default in  a lease or  other contract
except  a  lease  or  other  contract  which  is  the  subject  of  the dispute.
Indemnitee shall  cooperate fully to  make available  to the Indemnitor  and its
attorneys,  representatives  and  agents, all  pertinent  information  under its
control.  Indemnitee shall have the right  to elect to settle or compromise  all
other contested claims with respect to which  the Indemnitor has not, within the
Claim  Answer  Period,  acknowledged  in  writing  (i) liability  therefor,  and
(ii) its  election to assume full responsibility for the settlement, compromise,
litigation and payment of such claim.

               (c)  Final Claims Statement.   At such time as  Damages for which
the  Indemnitor is liable hereunder are incurred by Indemnitee by actual payment
thereof or by entry of a final judgment, Indemnitee shall forward a Final Claims
Statement  to  the Indemnitor  setting  forth  the  amount  of such  Damages  in
reasonable detail on an  itemized basis.  Indemnitee shall supplement  the Final
Claims Statement  with such supporting  proof of loss (e.g.  vouchers, cancelled
checks,  accounting summaries,  judgments, settlement  agreement,  etc.) as  the
Indemnitor may reasonably request  in writing within 30 days after  receipt of a
Final Claims Statement.   All amounts reflected on Final Claims Statements shall
be paid promptly by Indemnitor to Indemnitee and Indemnitee shall have the right
to immediate payment of proceeds  from insurance policies paid to Indemnitor  in
connection with the claim for which the indemnification right arose.

               (d)  Survival  of Indemnification.  Any other provision hereof to
the contrary  notwithstanding, the parties  agree that  the representations  and
warranties of the  parties contained in this  Agreement and in any  certificates
delivered pursuant to  this Agreement shall survive for a period of one (1) year
after the  Closing  Date for  purposes of  this Article  12,  regardless of  any
investigation made by  either party  prior to the  date hereof  or prior to  the
Closing Date,  provided, however, that  the one-year limitations period  in this
Section shall not apply to any of Sellers' representations and warranties (and 

                                      -41-

<PAGE>

any claims for indemnification therefor)  relating to Asbestos Claims, Taxes and
Environmental  Matters.     Buyers  and  Sellers  shall  only   be  entitled  to
indemnification  under this  Article  12  for  breaches of  representations  and
warranties if a written notice describing the claim for which indemnification is
sought is signed by the President or any Vice President  of Buyer or Sellers, as
the case may be, and is submitted to Sellers or Buyers, as the  case may be, not
later than  one year  following the  Closing Date,  except in  the case of  such
Asbestos  Claims,  Taxes and  Environmental  Matters.    Except for  claims  for
indemnification based upon Asbestos Claims, Taxes and Environmental Matters, any
claim  for  indemnification  pursuant  to   this  Article  12  for  breaches  of
representations and warranties not made prior to the expiration of such one-year
period  shall be  extinguished,  and  all  representations and  warranties  with
respect  to which no  claim is  made prior  to the  expiration of  such one-year
period shall expire and be of no further force and effect.

               (e)  Actual Knowledge  Limitation.   Notwithstanding anything  in
this  Agreement   to  the  contrary,   Buyers  may   not  assert  a   claim  for
indemnification under this  Article 12 with  respect to a  breach of a  specific
representation or warranty made by Sellers if Buyers had actual knowledge of the
existence of  such breach at the time  of Closing, and Sellers may  not assert a
claim for  indemnification under  this Article  12 with  respect  to a  specific
breach  of a  representation or warranty  made by  Buyers if Sellers  had actual
knowledge of such breach at the time of Closing.

               (f)  Minimum Dollar Limitation.  The parties hereto agree that no
violations  or  breaches  under  any one  or  more  of  the representations  and
warranties of Sellers  or Buyers  set forth  in this Agreement  shall support  a
claim for  Damages unless and until  Damages attributable to all  violations and
breaches exceed on a cumulative and aggregate basis the sum of $150,000 and that
in such  event Sellers and Buyers shall  only be obligated to  indemnify a party
entitled to indemnification  under this Article 12 for  cumulative and aggregate
Damages that  exceed $150,000, provided,  however, that such limitation  in this
Section shall not  apply to any of Sellers' representations  and warranties (and
any claims for indemnification therefor)  relating to Asbestos Claims, Taxes and
Environmental Matters, and Buyers shall be entitled to indemnification hereunder
from  Sellers only to  the maximum aggregate  extent of $7.5  million, provided,
however, that such limitation in this Section shall not apply to any of Sellers'
representations and  warranties (and  any claims  for indemnification  therefor)
relating to Asbestos Claims, Taxes  and Environmental Matters, and Sellers shall
be  entitled  to indemnification  hereunder  from  Buyers  only to  the  maximum
aggregate extent of $7.5 million.

               (g)  Impact  of Insurance  Proceeds.   The gross amount  which an
Indemnitor is liable  to, for, or on  behalf of the Indemnitee pursuant  to this
Section   (the  "Indemnifiable  Loss")  shall  be  reduced  (including,  without
limitation, retroactively) by any insurance proceeds actually recovered by or on
behalf of  such  Indemnitee related  to  the Indemnifiable  Loss,  and shall  be
further reduced to  take account of  any tax benefit  to the Indemnifee  arising
from the Indemnifiable Loss.  If an Indemnitee shall have received or shall have
had paid on its behalf an indemnity  payment in respect of an Indemnifiable Loss
and shall subsequently receive directly  or indirectly insurance proceeds or tax
benefits in respect of such Indemnifiable Loss, then such Indemnitee shall pay 

                                      -42-

<PAGE>

to such Indemnitor the amount of such insurance proceeds and tax benefits or, if
less, the amount  of such indemnity payment.  For purposes  of this Section, tax
benefits arising  from an  Indemnifiable Loss shall  be determined  after taking
into account the  tax detriment, if any,  arising from the receipt  of insurance
proceeds or  indemnification payments by or on behalf  of the Indemnitee and the
tax  benefit,  if  any, to  the  Indemnitee  arising from  any  payments  to the
Indemnitor.

               (h)  Dispute  Resolution.   All disputes  under  this Article  12
shall be  settled by  arbitration in Pittsburgh,  Pennsylvania, before  a single
arbitrator  pursuant  to  the  rules of  the  American  Arbitration Association.
Arbitration may be  commenced at  any time  by any party  hereto giving  written
notice to each other  party to a dispute that such dispute  has been referred to
arbitration under  this Section.  The arbitrator shall  be selected by the joint
agreement of Buyers  and Sellers, but  if they do  not so agree  within 20  days
after the  date of the  notice referred to  above, the  selection shall be  made
pursuant  to the  rules  from  the  panels of  arbitrators  maintained  by  such
Association.   Any award  rendered by  the  arbitrator shall  be conclusive  and
binding upon the parties hereto; provided, however, that any such award shall be
accompanied by a  written opinion of the  arbitrator giving the reasons  for the
award.  This provision for arbitration shall  be specifically enforceable by the
parties, and  the decision of  the arbitrator  in accordance  herewith shall  be
final  and binding and there shall be no  right of appeal therefrom.  Each party
shall pay its  own expenses of  arbitration and the  expenses of the  arbitrator
shall be paid  one-half by  Sellers and one-half  by Buyers; provided,  however,
that if in  the opinion of the  arbitrator any claim for indemnification  or any
defense or  objection thereto  was unreasonable, the  arbitrator may  assess, as
part of his award, all or any part of the expenses of the arbitrator against the
party raising such unreasonable claim, defense or objections.

          To the extent that arbitration  may not be legally permitted hereunder
and the  parties to any dispute  hereunder may not  at the time of  such dispute
mutually agree to submit  such dispute to arbitration, any party  may commence a
civil action in a court of appropriate jurisdiction to solve disputes hereunder.
Nothing contained  in this Section shall  prevent the parties  from settling any
dispute by mutual agreement at any time.

or such substituted address or attention as any party shall have given notice to
the others in writing in the manner set forth in this Section 13.1.

          13.2 Amendment.  This Agreement may be amended or modified in whole or
in  part only  by an  agreement in  writing executed  by all parties  hereto and
making specific reference to this Agreement.

          13.3 Counterparts.   This  Agreement may  be executed  in one  or more
counterparts, all of which taken together shall constitute one instrument.

          13.4 Binding  on  Successors and  Assigns.   This  Agreement  shall be
binding upon, inure  to the  benefit of and  be enforceable  by and against  the
parties hereto  and their respective  successors and assigns in  accordance with
the terms hereof; and in the event  any party hereto is dissolved or  liquidated
after the Closing Date, the obligations of such party shall automatically become
the  obligations  of the  person(s)  to  whom  are  distributed the  assets  and
properties of such party in  accordance with applicable corporate law.   Sellers
may not assign  their interest under  this Agreement without  the prior  written
consent of Buyers.   Buyers shall have  the right to  designate any one or  more
existing or  hereafter formed subsidiaries  or affiliates of Buyers  to purchase
the Assets and assume the Assumed  Liabilities of any Seller, provided (a)  such
designation shall  not relieve such  Buyers of their obligations  hereunder, and
(b) with respect to  the Assets and Assumed Liabilities acquired  and assumed by
such designee, such designee shall constitute a "Buyer" thereof for all purposes
of this Agreement,  including without limitation Article 12  hereof.  Otherwise,
Buyers  shall  have no  right to  assign  their interests  under  this Agreement
without the prior written consent of Sellers.

          13.5 Severability.    In  the  event  that  any  one  or  more of  the
provisions  contained in  this Agreement  or  any application  thereof shall  be
invalid,  illegal or  unenforceable in  any respect,  the validity,  legality or
enforceability  of the  remaining provisions  of  this Agreement  and any  other
application  thereof  shall not  in  any way  be affected  or  impaired thereby;
provided, however, that to the extent permitted by applicable  law, any invalid,
illegal,  or  unenforceable provision  may  be  considered  for the  purpose  of
determining the intent of the parties in connection with the other provisions of
this Agreement.

          13.6 Waivers.   The parties may, by  written agreement, (a) extend the
time for the performance of any of the obligations or other acts of the parties 

                                      -45-

<PAGE>

hereto,  (b) waive any  inaccuracies in  the representations  contained in  this
Agreement or  in any  document delivered pursuant  to this  Agreement, (c) waive
compliance with, or modify, any of the covenants or conditions contained in this
Agreement, and (d) waive or modify performance of any of the obligations  of any
of the parties hereto; provided,  that no such waiver or failure  to insist upon
strict compliance with  such obligation, covenant, agreement  or condition shall
operate  as  a waiver  of,  or  an  estoppel  with respect  to,  any  subsequent
insistence upon such strict compliance other than  with respect to the matter so
waived or modified.

          13.7 Publicity.  Any  public announcements concerning  the transaction
contemplated  by this  Agreement  shall be  jointly  planned and  simultaneously
released by  Buyers and  Sellers, and  none of  them shall  act  in this  regard
without the prior  written approval of the  others, which approval shall  not be
unreasonably withheld.

          13.8 Headings.  The  headings in the sections and  subsections of this
Agreement and in the Schedules are  inserted for convenience only and in no  way
alter,  amend, modify,  limit or  restrict  the contractual  obligations of  the
parties.

          13.10     Expenses.  Except to  the extent otherwise provided in  this

          13.11     Confidentiality.   Prior  to the  Closing Date  (and  if the
Closing does not occur, for a period of five years from the date hereof), Buyers
and  Sellers (and their  respective employees,  agents, auditors,  attorneys and
other authorized representatives)  shall not, without  prior written consent  of
the party  divulging information under  this Agreement (the  "Divulging Party"),
communicate or divulge  to any person  or entity  or use for  their benefit  any
information (other than information otherwise available  or which becomes public
other  than as  a  result of  their  action)  concerning the  Divulging  Party's
financial  condition or  business,  or  concerning  any  marketing  information,
equipment,  methods, research, clients, contracts, suppliers, customers or other
data  of  or  relating to  the  Divulging  Party or  other  confidential matters
possessed, owned or  used by such Divulging  Party that may be  communicated to,
acquired by  or  learned by  them.    All correspondence,  records,  files,  tax
returns, financial  statements and other  data relating to such  Divulging Party
which shall come into the possession of Buyers or Sellers, as the case may be, 

                                      -47-

<PAGE>

shall remain  the sole property of such Divulging Party pending the consummation
of  the  transactions contemplated  hereby.   If  the  transactions contemplated
hereby are not consummated for any reason, then Buyers and  Sellers, as the case
may be,  shall return  all of  the foregoing  material to  the Divulging  Party,
together with any and all copies thereof made.  The terms of the Confidentiality
Agreement  dated January 28, 1994 are incorporated herein by reference and shall
specifically survive the execution of this Agreement.

          13.12     Survival.  Subject  to the provisions of  Section 12.2(d) of
this  Agreement, all  of  the  terms,  covenants,  warranties,  representations,
conditions, indemnity  obligations and other provisions of  this Agreement shall
survive and continue to remain in full force and effect after the Closing.

          13.13     Entire Agreement; Law  Governing.   Except as  set forth  in
Section 13.11 hereof, all prior  negotiations and agreements between the parties
hereto  are superseded  by this  Agreement,  and there  are no  representations,

               (i)  at  the election of Buyers in the circumstances contemplated
     in Section 7.3;

     be,  reasonably and  in good faith  deem it  impractical or  inadvisable to
     proceed in  view of  such legal proceeding or  threat thereof,  taking into
     account the potential expense and delay likely to be involved;

                                      -49-

<PAGE>

               (v)  at  any time  on or  prior to  the Closing  Date,  by mutual
     written consent of Buyers and Sellers; or

               (vi) at the  election of  Buyers or Sellers,  if Closing  has not
     occurred on or prior to August 31, 1994.

If this  Agreement so  terminates, it  shall become  null and void  and have  no
further force and effect, except as provided in Section 13.19(b), and except for
Section 13.11 which shall survive termination.

               (b)  If this Agreement is validly terminated pursuant to Sections
13.19(a)(i), (iv), (v) or (vi), and the transactions contemplated hereby are not
consummated  as described  above, this  Agreement shall  become void  and of  no
further force and effect, and neither party shall have any claim or liability to
the other  party  for  any  damages,  costs or  expenses  paid  or  incurred  in
connection with this Agreement or the transactions contemplated hereby.  If this
Agreement is validly terminated pursuant  to Sections 13.19(a)(ii) or (iii), and
the transactions  contemplated hereby are  not consummated  as described  above,
then this  Agreement shall become void and  of no further force  and effect, and
the terminating  party shall have  a claim  for liquidated  damages against  the
other party  in  an aggregate  amount not  to exceed  the  reasonable costs  and
expenses actually  paid or incurred to third parties  to the date of termination
in connection with the transactions contemplated hereby; provided, however, that
if  such termination  results  from a  failure  of any  condition  set forth  in
Sections 9.4,  9.7, 10.3 or  10.5, then  neither party shall  have any  claim or
liability to the other party for any damages, costs or expenses paid or incurred
in connection with  this Agreement or the transactions  contemplated hereby, and
provided further that  if Buyers terminate pursuant to Section 13.19(a)(ii) as a
result of Seller's failure to comply with Sections 9.1, 9.2, 9.3 and 9.6 of this
Agreement due  to reasons within  Sellers' reasonable control and  Sellers enter
into a  definitive agreement to sell the Business, either  in the form of a sale
of assets or  stock or  a merger  of other acquisition  transactions within  six
months of  such termination, the liquidated damages payable by Sellers to Buyers
shall be  the greater  of $1,000,000 or  twice Buyer's  reasonable out-of-pocket
expenses actually paid to  third parties or incurred to the  date of termination
of this Agreement in connection with the transactions contemplated hereby.  This
Agreement may  not be  terminated by  either party  except as  provided in  this
Section 13.19.  Neither  party shall have  any liability to  the other party  in
respect of a valid termination of this  Agreement except to the extent set forth
in this Section 13.19, and the parties hereby expressly waive any other legal or
equitable rights, remedies or causes of action.

contrary, Buyer shall not  have the right to terminate this  Agreement and there

Rockdale, Illinois and as reflected in the April Balance Sheet are lost, damaged
or destroyed from  May 1, 1994 to the Closing Date,  provided, however, that, if
the Closing occurs, Buyers  shall be entitled to receive  any insurance proceeds
paid with  respect to  such loss,  damage or  destruction, and  Buyers shall  be
responsible for any deductible or co-pay amount with respect thereto.  For all 

                                      -50-

Sellers  except those  salaried employees  located in  Sellers' Bala  Cynwyd and
Audubon, Pennsylvania  offices, Buyers shall indemnify and hold harmless Sellers
on account  of  any claims  of  such employee  or  applicable U.S.  or  Canadian
governmental  authorities for  termination  and/or severance  benefits, wrongful

such  employees, whether  under United  States or  Canadian law.    In addition,
Buyers shall be  responsible for, and shall indemnify and  hold Sellers harmless

their employment by Buyers, whether arising under United States or Canadian law,
provided that  the Buyers shall not assume liability  for claims made in respect
of  any person who was not employed by  Sellers as of the date of Closing unless
such   claims  or  potential  claims  directly   result  from  the  transactions
contemplated by this Agreement or have been disclosed by Sellers and accrued for
in the April Balance Sheet.  Buyers  shall provide health insurance coverage for
all employees  hired by  Buyers beginning  on the  date of  their employment  by
Buyers, consistent with  the coverage provided by Buyers or  their affiliates to

standing under the  laws of Delaware, and is duly qualified and in good standing
as a foreign  corporation authorized to transact  business and to own  and lease
property in each jurisdiction in which, by reason of the nature of the  business
conducted by  it or the character or location  of the properties owned or leased
by it, the  failure to so qualify  would have a  material adverse effect on  the
business or assets of Green.

     2.   The  execution  and  delivery  of   this  Joinder  by  Green  and  the
performance by Green of the obligations set forth in this Joinder have been duly

     3.   The execution, delivery and performance  of this Joinder by Green will
not contravene any provision of Green's articles of incorporation or by-laws and

decree,  order or rule of any  court or governmental agency  or any provision of
applicable law which is binding on Green.

     4.   Except as may  be specified in the Agreement,  no consent by, approval
or authorization of  or filing, registration or qualification  with any federal,
state or local authority,  or any corporation, person or other entity (including
any party  to  any  contract  or  agreement with  Green)  is  required  for  the
execution,  delivery or performance  of this Joinder  by Green  or in connection
with the performance of Green's obligations hereunder.

their obligations required to be performed under  the Agreement on or before the
Closing Date, this Paragraph 5 and the obligations of Green under this Paragraph
5 and this Joinder shall terminate and be of no further force and effect.

                             NOTE PURCHASE AGREEMENT


          THIS NOTE PURCHASE  AGREEMENT is made as  of July 29, 1994  among A.P.
GREEN INDUSTRIES, INC., a Delaware  corporation (the "Company"), APG Lime Corp.,
a Delaware corporation ("Lime Corp"),  A.P. Green Refractories (Canada), Ltd., a

laws of  the United  Kingdom ("U.K.  Refractories"), Detrick  Refractory Fibers,
Inc.,  a Mississippi corporation ("Detrick"), General Acquisition Corporation, a
Delaware  corporation  ("Acquisition   Corp.")  and  1086215  Ontario   Inc.,  a
corporation  organized  under  the  laws  of the  province  of  Ontario,  Canada
("Ontario Inc."),  (as to  Lime Corp.,  Canada Refractories, U.K.  Refractories,
Detrick,  Acquisition  Corp.  and  Ontario   Inc.,  the  "Guarantors")  and  the
purchasers set forth in Schedule I (the "Purchasers").  In consideration  of the
agreements contained herein, and for  other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties agree:

          Section 1.  Notes; Payments.

          1.1   Issuance.  The  Company will authorize the issuance  and sale of
$25,000,000 in  aggregate principal  amount of its  senior unsecured  notes (the
"Notes")  due as provided in  Section 1.2(a).  The Notes  shall bear interest at
the rate of  8.55% per annum; provided,  however, that if the  initial rating on
the Notes from  the National Association of Insurance  Commissioners ("NAIC") is
below "2", the Notes shall bear  interest through July 29, 1996, at 9.55%;  and,
provided  further, regardless of  the initial NAIC  rating on the  Notes, at any
time after the issuance of the Notes that the NAIC rating on  the Notes is below
"2", the Notes  shall bear interest  at 9.55%.  Interest  on the Notes  shall be
payable semi-annually as provided in Section 1.2(a).  The Notes  shall be in the
form of Exhibit 1.1.   Interest on the Notes shall be computed on the basis of a
360-day  year  of twelve  30-day  months.   Interest  on  any overdue  principal
(including any overdue  prepayment of principal); on the  Make-Whole Premium, if
any;  to  the extent  permitted by  applicable  law, on  any unpaid  and overdue
interest; and on other Obligations shall be paid at the rate per annum 2%  above
the otherwise applicable rate.

          1.2   Payments; Prepayments.

                (a)   Regular Payments.  Commencing on July 29, 1996 the Company
          shall make  annual payments of principal with  respect to the Notes in
          accordance with the amortization schedule  attached to each Note.  The
          Company shall make  its final payment of principal with respect to the
          Notes on July 29, 2001.   Commencing on January 29, 1995, the  Company
          shall make semiannual payments, in arrears, of all accrued interest on
          January 29 and July 29 of each year.  All payments and prepayments of 

                                       -1-

<PAGE>

          principal, interest and  Make-Whole Premium, if any, shall  be made in
          immediately available  funds on  the date  specified therefor  (or, if
          such day  is not  a Business  Day, on  the  succeeding Business  Day),
          before  12:00  noon,  New  York  time, and  to  the  account  of  each
          Noteholder, respectively,  as set forth  in Schedule I, or  such other
          account as each Noteholder may designate in writing from time to time.
          The Company shall give each Noteholder  contemporaneous notice of each
          payment made to such Noteholder, such notice to be made to the address
          indicated on Schedule I,  or such other address as each Noteholder may
          designate in writing  from time to time.   All such payments  shall be
          made, without  setoff or counterclaim  and without reduction  for, and
          free  from, any  and all  present  or future  taxes, levies,  imposts,
          duties,  fees,  charges,  deductions,  withholdings,  restrictions  or
          conditions of  any nature imposed  by any government or  any political
          subdivision  or  taxing  authority thereof  (but  excluding  any taxes
          measured by the overall net income of any Noteholder).

                (b)   Optional Prepayments.   On any interest payment  date, the
          Company may prepay, in full or in part, the Notes; provided, that such
          prepayment is  accompanied by payment  of all accrued interest  to the
          date of prepayment and a Make-Whole  Premium, if any, determined as of
          the  date of the  prepayment; and provided  further, that  in no event
          shall such  prepayment be less  than the principal being  prepaid plus
          all  accrued interest  to the  date of  prepayment.   Prepayments with
          respect  to  fewer  than  all  holders are  not  permitted.    Partial
          prepayments shall  be made  pro rata  to all  holders of  Notes.   The
          Company shall give notice to each Noteholder at least 30 days, but not
          more than 60 days, prior to the intended prepayment date.  Such notice
          shall specify the prepayment date, and, as to each Note being prepaid,
          the outstanding principal amount thereof, the accrued interest thereon
          (through  the  scheduled  prepayment  date)  and  an  estimate  of the
          applicable Make-Whole Premium due in respect of such prepayment.  Such
          notice  shall  contain such  data  and  detailed calculations  as  are
          necessary  to  confirm  the computation  of  the  estimated Make-Whole
          Premium  set forth  therein.   The  amount of  the Make-Whole  Premium
          actually paid shall  be adjusted from the foregoing  estimate based on
          the most recent information available as of  the day prior to the date
          of prepayment as required  by Section 11.39.  On the day  prior to the
          date of prepayment,  the Company shall give to  each Noteholder notice
          of the actual amount of Make-Whole Premium.  Such notice shall contain
          such data  and detailed calculations  as are necessary to  confirm the
          computation of the actual Make-Whole Premium contained therein.  Any 

                                       -2-

<PAGE>

          partial  prepayments under this  Agreement applied to  the Notes shall
          reduce in  inverse order of maturity all  remaining scheduled payments
          of  principal,  pro  rata  to  all  holders  of  Notes to  which  such
          prepayment applied.

                (c)   Note Purchases.  The Company will not, and will not permit
          any Subsidiary  or Affiliate  to, acquire, directly  or indirectly  by
          purchase or  prepayment or  otherwise, any  of the outstanding  Notes,
          except in accordance with the terms of this Agreement and the Notes.

                (d)   Contingent Prepayments  Upon Change  of Control.   In  the
          event of the occurrence of a Change of Control, the Company shall give
          prompt written  notice thereof to  each Noteholder by  registered mail
          and shall  confirm  such notice  by  prompt telephonic  advice,  which
          notice shall  contain a written,  irrevocable offer by the  Company to
          prepay, on a  date specified in such  notice (which date shall  be not
          less than 30 days  and not more  than 60 days after  the date of  such
          notice), the Notes held by such Noteholder  in full (and not in part).
          Upon the  acceptance of such  offer by  such Noteholder mailed  to the
          Company at least 10 days prior to the date of prepayment  specified in
          the Company's  offer, such prepayment  shall be made at  the principal
          amount  of the Notes so  prepaid, plus accrued  and unpaid interest on
          the  Notes, plus a  Make-Whole Premium.   Any offer by  the Company to
          prepay the Notes pursuant to  this Section 1.2(d) shall be accompanied
          by  an Officers'  Certificate certifying  that the conditions  of this
          Section 1.2(d) have  been fulfilled and specifying  the particulars of
          such fulfillment.   If  the Noteholders shall  accept such  offer, the
          principal  amount of  such Notes shall  become due and  payable on the
          date specified in such offer.  In the event that there shall have been
          a  partial prepayment  of  the  Notes under  this  Section 1.2(d)  the
          Company shall promptly  give notice to the  Noteholders accompanied by
          an Officer's Certificate setting forth the principal amount of each of
          the Notes  that was prepaid  and specifying how  each such amount  was
          determined, and if some but not all of the Notes were prepaid, setting
          forth  the reduced  amount  of  each  required  prepayment  thereafter
          becoming due with respect to the Notes under Section 1.2(a).

          1.3   Registration.    The  Company shall  maintain  at  its principal
office a  register with respect  to ownership and  transfers of the Notes.   The
Company  may in  good  faith rely  on the  register  for the  purpose of  making
payments on the  Notes and for all  other purposes related to  actions taken and
notices given in respect of the Notes.  For purposes of this Agreement,  the 

                                       -3-

<PAGE>

Person  in whose name a Note  is registered shall be  deemed the "holder" of the
Note and a Noteholder hereunder.

          1.4   Transfer or Exchange.  Upon written request of the holder of any
Note and the surrender of such Note for transfer or exchange, the Company shall,
without charge:  (a) issue  a new  Note or  Notes  in respect  thereof, in  such
denominations as may  be requested by the  holder to equal the  unpaid principal
balance of the  Note surrendered, and made payable to the holder, its nominee(s)
or the transferee, as  requested by the holder, provided that the holder may not
request a new Note in a  denomination less than $500,000 or, if  the outstanding
principal  of such Note is  less than $500,000, in a  denomination less than the
outstanding principal amount of such Note; and (b) register such new  Note(s) in
the  name of the party to whom it is  made payable.  Any transferee shall by its
acceptance of a Note make for the benefit of the Company the representations set
forth in Sections 2.2(a)  and (b) hereof and, furthermore, a representation that
the transfer will not require the Notes or any portion thereof to be  registered
under the  '33 Act.  New Notes  shall be of like tenor  to the Notes surrendered
therefor and shall be  dated the date to which interest was last  paid, or if no
interest has been paid, July 29, 1994, so that there is no loss of interest with
respect thereto.  Upon the request of any Noteholder, the Company shall, without
charge,  provide  such data  as  may  be  reasonably  necessary to  enable  such
Noteholder, upon a transfer  of any Note, to  comply with Rule 144A (or  similar
safe harbor  provision) of the  Securities and Exchange  Commission.   Such data
shall be provided within 15 days after request by the Noteholder.

          1.5   Replacement.  In the  case of the loss, theft, or destruction of
any Note, the holder thereof shall be entitled, without charge, to a replacement
Note by delivering to the Company the affidavit  of a responsible officer of the
holder,  testifying that  the  Note  has  been lost,  stolen  or  destroyed,  as
applicable,  and an  unsecured indemnity  agreement  with respect  to the  lost,
stolen or destroyed Note.  In the case of the mutilation of any Note, the holder
thereof shall be  entitled, without charge, to a replacement  Note by delivering
to the Company such mutilated Note along with a written request for replacement.
Replacement Notes shall be issued in the  amount of the unpaid principal balance
of the original Notes, shall be of like tenor to the original Notes and shall be
dated the date to which interest was last paid, or if no interest has been paid,
July 29, 1994, so that there is no loss of interest with respect thereto.

          1.6   Payments.   All payments  due under the  Notes or on  any of the
other Obligations  shall be  made  without tender  of the  Notes in  immediately
available funds by  federal wire transfer in  lawful money of the  United States
before 12:00 noon, New York time, on the due date therefor to the account of the

                                       -4-

respective holder  as set  forth on the  attached Schedule  I or  at such  other
account as the holder may designate in writing from time to time.

          Section 2.  Sale and Purchase of Notes.

          2.1   Agreement.    The Company  agrees  to  issue  and sell  to  each
Purchaser, and each Purchaser agrees to purchase from the Company, Notes  in the
principal amount set forth  in Schedule I with  respect to such Purchaser.   The
purchase price for the Notes shall be 100% of the principal amount thereof.

          2.2   Purchasers' Representations.   Each Purchaser hereby  represents
and warrants, as to itself, that:

                (a)   Purchase  for Investment.  The Purchaser is purchasing the
          Notes  for  its own  account  or for  one  or  more separate  accounts
          maintained by it, in each case  for investment and not with a  view to
          distributing or selling any  of the Notes; provided,  that disposition
          of the  Notes  shall  at  all  times be  within  the  control  of  the
          Purchaser.

                (b)   Source  of  Funds.   As  to  such  Purchaser, one  of  the
          following applies:

                      (i)   no part of its  purchase of Notes hereunder will  be
                made out  of any  trust fund held  by it  in which  any employee
                benefit  plan has  any  interest  or, if  such  Purchaser is  an
                insurance  company,  will be  made  out  of  the assets  of  any
                separate  account maintained by it in which any employee benefit
                plan has any  interest, unless the funds used  by such Purchaser
                to purchase such Notes are assets of a governmental plan; or

                      (ii)  if  any part  of the purchase  by such  Purchaser of
                such Notes hereunder may be made  out of any such trust fund  or
                separate   account,  either  (1)  such  separate  account  is  a
                "guaranteed contract separate account"  subject to the exception
                contained in 29 C.F.R. 2510.3-101, or (2) such trust fund is and
                will remain (for so long as it holds such Notes) entitled to the
                exemptions provided  by Prohibited  Transaction Class  Exemption
                91-38 issued  by the United  States Department of Labor  or such
                separate  account  is  entitled to  the  exemptions  provided by

                the Company in writing each  employee benefit plan which has any
                greater than 10%  interest in such fund or  separate account; or
                (3) such separate account contains only the assets of a specific

                                       -5-

<PAGE>

                employee benefit plan,  complete and accurate information  as to
                the identity of which it has delivered to the Company; or

                      (iii) it is a  "qualified professional  asset manager"  or
                "QPAM" (within the  meaning of Part V  of prohibited Transaction
                Class Exemption 84-14 (the "QPAM Exemption")), all of such funds
                constitute assets of an "investment fund" (within the meaning of
                Part V of the QPAM Exemption) managed by it, no employee benefit
                plan's  assets which are included  in such investment fund, when
                combined with  the assets  of all  other employee  benefit plans
                established  or  maintained  by  the  same  employer  or  by  an
                affiliate  (within the  meaning of section  V(c)(1) of  the QPAM
                Exemption)   of  such   employer  or   by   the  same   employee
                organization, exceed 20%  of the total client  assets managed by
                it,  the conditions  of  Part  I(g) of  the  QPAM Exemption  are
                satisfied, and it has disclosed  to the Issuer the names  of all
                employee  benefit  plans  whose  assets  are  included  in  such
                investment fund.

          As  used  in the  preceding  Sections  2.2(a)  and 2.2(b),  the  terms
          "separate account",  "employee benefit  plan" and  "governmental plan"
          shall have the meanings assigned to them in ERISA.

                (c)   Fees.   The  Purchaser has  not dealt  with any  broker or
          finder besides Bear, Stearns & Co. Inc. in respect  of the transaction
          contemplated hereby.

          Section 3.  Closing.  The sale and  purchase of the Notes contemplated
by Section 2 shall be consummated at a closing (the "Closing") to occur at 11:00
a.m. (Central Daylight  time) on July  29, 1994, or  such later date  as may  be
mutually agreed by the  parties.  The Closing shall take place at the offices of
Thompson & Mitchell in St. Louis,  Missouri.  At the Closing, the  Company shall
deliver to each  Purchaser the Notes  to be purchased  by such Purchaser.   Such
Notes shall be delivered to each Purchaser in the form of a single note (or such
greater number of  Notes as the  Purchaser may request)  to be purchased by  the
Purchaser, shall  be dated as  of the  date of  the Closing, and  shall be  made
payable to and  registered in the  name of that Purchaser  or its nominee(s)  as
required  by  the  Purchaser.    Upon  tender  of  delivery  of  the  Notes, and
satisfaction of the conditions  precedent set forth in Section 4, each Purchaser
shall pay to the Company, in immediately available funds, the purchase price for
the Notes  sold to such Purchaser.  Failure of the Company to tender delivery of
the  Notes  or  failure of  the  respective  person or  persons  to  satisfy any
condition precedent  in Section 4 shall, at the option  of the Purchasers or any
of them, relieve the Purchasers of all further obligations hereunder or operate 

                                       -6-

<PAGE>

as a waiver of the Purchasers'  rights hereunder.  In such event, the Purchasers
shall also have all other rights and remedies available at law or in equity.

          Section 4.  Conditions Precedent.   The obligations of the  Purchasers
to  purchase the Notes are  subject to satisfaction  of the following conditions
precedent:

          Purchasers,   covering  all  matters   reasonably  requested   by  the
          Purchasers  or their counsel,  including, without limitation,  the due

          respective terms,  and certain other  matters set forth in  Section 5.
          Such  opinion shall  be  satisfactory  in form  and  substance to  the

course of business.  The execution  and delivery of its Operative Documents  and
the sale of the Notes to the Purchasers will not involve any transaction subject
to the  prohibitions of Section 406 of  ERISA or in connection with  which a tax
could be imposed under Section 4975  of the Code.  The foregoing  representation
is made in  reliance on the Purchasers'  representations in Section 2.2(b).   If
the name of any employee benefit plan has been disclosed to the Company pursuant
to Section 2.2(b)(ii), the  Company is not a  party in interest with respect  to
any  such plan and  securities of the  Company are not  employer securities with
respect to any such plan.  With respect to each employee benefit plan identified
in writing to the Company in accordance with Subsection 2.2(b)(iii), neither the
Company nor any  "affiliate" thereof (as defined  in section V(c) of  Prohibited
Transaction Class Exemption 84-14 (the "QPAM" Exemption")) has at this time, and
has not  exercised  at any  time within  the preceding  year,  the authority  to
appoint or terminate the "QPAM" (as defined in the QPAM Exemption) identified in
accordance with Section 2.2(b)(iii) as  manager of any of the assets of any such
plan or  to negotiate the  terms of any  management agreement with such  QPAM on
behalf  of any such  plan and the Company  is not an  "affiliate" (as defined in
Section V(c) of the QPAM Exemption) of  such QPAM.  The Company has delivered to
the Purchasers a list of all  employee benefit plans (other than welfare  plans)
with respect to  which it is a party  in interest and with respect  to which its
securities are employer securities.  As used in this section the terms "employee
benefit plan,"  "welfare plan,"  "party in  interest" and  "employer securities"
have the meanings assigned to them in ERISA.

          5.17  Material Contracts.  There is no pending or threatened breach or
declaration  of  default  under any  material  management  agreement, consulting
agreement  or any  other  agreement between  it or  its  Subsidiaries and  their
respective   shareholders,  directors,  officers  or  other  Persons  exercising
significant  control  or  policy-making  authority  over or  within  it  or  its
Subsidiaries  and all  other material  contracts  which individually  or in  the
aggregate would have a Material Adverse Effect.

benefits.  It and its Subsidiaries have withheld all amounts required  by law to
be withheld from  their employees' wages and salaries and are not liable for any
arrears of wages or any taxes, interest or  penalties for failure to comply with
the foregoing.    The  Company  has  fully and  accurately  disclosed  to    the
Purchasers   the  status  of  all  negotiations  pertaining  to  all  collective
bargaining agreements to which it or its Subsidiaries are a party.  There are no
material  controversies pending  nor  is  the Company  aware  of any  threatened
controversy between the Company or its Subsidiaries and any of their respective 

                                      -16-

employees.   Neither the Company nor  any of its Subsidiaries  is a party to any
labor  dispute and there are no strikes or  walkouts pending, nor is the Company
aware of any  threatened dispute, strike or  walkout, with respect to  any labor
contract to which the Company or any Subsidiary is a party.

          5.19  Intellectual Property.  It and  its Subsidiaries own or have the
right to  use, without payment  to any  third party,  all Intellectual  Property
material to the  operation of their  business.  Except  as disclosed in  Section
5.19  of  Schedule III,  to  the  best of  its  knowledge,  there are  no  Liens
encumbering the Intellectual Property and no such Intellectual Property owned or

arising from any product or the packaging therefor produced, sold or distributed
by it or any Subsidiary.

          5.22  Insurance.   It  has in  full force  and effect  insurance which

                (c)   costs   and  expenses,   including,  without   limitation,
          out-of-pocket  costs incurred in connection with or as a result of any
          Potential  Event  of Default  or  Event  of  Default hereunder  or  in
          connection with  any  enforcement  by  any Noteholder  of  its  rights
          hereunder or under any Operative Document; and

                (d)   documentary, stamp,  or similar taxes  (including interest
          and  penalties, if  any) payable in  respect of this  Agreement or any
          Note, regardless of when assessed.

Except as otherwise  provided herein, any such  costs and expenses shall  be due

more of its  Subsidiaries in the conduct  of such entity's business  (other than
those being  diligently contested  in  good faith by appropriate  procedures and
with  respect  to which  adequate  reserves in  accordance with  GAAP  have been

          Section 7.  General Negative Covenants.

          7.1   ERISA.   The Company shall not, and shall  not permit any of its
Subsidiaries or any Related Person to:

                (a)   (i) engage in any transaction in connection with which the
          Company,  any Subsidiary  or any  Related Person  could be  subject to
          either section 502(i) of ERISA or a tax imposed by section 4975 of the
          Code,  (ii) fail to  make full payment  when due of  all amounts which
          would  be deductible  by the  Company, the  Subsidiary or  any Related
          Person and which, under the provisions of  any Plan, applicable law or
          applicable   collective  bargaining   agreement,   the  Company,   the
          Subsidiary or any  Related Person is required to  pay as contributions
          thereto, or (iii) permit to exist any accumulated  funding deficiency,
          whether or not  waived, with respect to any  Plan, if, in the  case of
          any of sub- division (i), (ii) or (iii) above, such penalty or tax, or
          the failure to make such payment, or the existence of such deficiency,
          as the case may be, could have a Material Adverse Effect;

                (b)   permit the amount of unfunded current liabilities  (within
          the  meaning  of  section  302(d)(8)(A)  of  ERISA)  under  all  Plans
          maintained at such time by the Company, its Subsidiaries or any of its
          Related  Persons  to  exceed  $15  million  on  a consolidated  basis;
          provided, however, that at all  times the Company and its Subsidiaries
          shall be in compliance with law; or

                (c)   permit  the  aggregate   complete  or  partial  withdrawal
          liability under Title IV of ERISA which is due and unpaid with respect
          to all Multiemployer Plans  incurred by the Company, its  Subsidiaries
          or any Related Person to exceed $5 million.

          7.2   Merger and Consolidation.  The  Company shall not, and shall not
permit any  of its  Subsidiaries to, consolidate  with or  merge into  any other
entity  or  permit  any other  entity  to  consolidate with  or  merge  into it.
Notwithstanding the foregoing, any Subsidiary may merge into the Company or into
another  wholly-owned Subsidiary.   Furthermore, notwithstanding  the foregoing,
the Company may  enter into such  a consolidation or  merger transaction with  a
company if no Event of Default or Potential Event of Default has occurred and is
continuing and  if, immediately after  the consummation of such  transaction, no
Event of Default  or Potential Event  of Default would  exist hereunder and  the
successor entity could, without the occurrence of an Event of Default hereunder,
incur at least $1   of additional Funded  Debt; provided, however, that (a)  the
surviving corporation  in such  transaction is  a solvent corporation  organized
under the laws of a state of the United States of America, with its principal 

                                      -25-

<PAGE>

place  of business  in the United  States, and  doing business primarily  in the
United States and/or  Canada; and (b)  the surviving corporation assumes  all of
the Company's Obligations.

          7.3   Sales or  Other  Dispositions of  Assets.   Except as  expressly
provided in Section 7.4, during any Fiscal Year the Company shall not, and shall
not  permit any  of  its Subsidiaries  to,  sell, lease,  transfer or  otherwise
dispose of any of  its assets (including,  without limitation, the stock,  other
voting securities of or evidence of indebtedness from any Subsidiary) other than
in the  ordinary course of  business unless the  aggregate book value  of assets
sold, leased or otherwise disposed of in such Fiscal Year by the Company and its
Subsidiaries (a) does not exceed  10% of the Consolidated Total Tangible  Assets
of the  Company and  its Subsidiaries  as of  the end  of the  Fiscal Year  most
recently ended; and, (b) such sale of assets together with prior sales of assets
from and after the date of this Agreement does not, on a cumulative basis exceed
25% of  Consolidated Total Tangible  Assets.   The foregoing shall  not prohibit
sales of  assets the  proceeds of  which are  used  within one  year to  acquire
productive assets used  in the  ordinary course  of business of  the Company  or
Subsidiary and having at least substantially comparable value; or (ii) assets by
any  Subsidiary  to  the  Company  or  to  any  other  wholly-owned  Subsidiary.
Notwithstanding the  foregoing, the Company  and any Subsidiary shall  not sell,
lease, transfer or  otherwise dispose of assets if immediately  before and after
such event  an Event of  Default or Potential  Event of  Default exists.   In no
event  shall the Company sell stock of a  Subsidiary if the remaining stock held
by  the  Company shall  be  less  than 51%  of  the  outstanding  stock of  such
Subsidiary.

          7.4   Additional Stock.  The Company shall not:  (i) permit any of its
Subsidiaries  to  issue  any  additional  shares of  capital  stock,  voting  or
non-voting, any warrants,  options or other rights to  acquire capital stock, or
any  securities convertible  into capital  stock, except  to  the Company  or to
another wholly-owned Subsidiary; or (ii)  sell, transfer or otherwise dispose of
any capital  stock, voting or non-voting,  warrants, options or other  rights to
acquire capital stock, or any securities convertible into  capital stock, of any
Subsidiary except to another wholly-owned Subsidiary.

          7.5   Other Agreements.   The Company shall not, and  shall not permit
any of its  Subsidiaries to, enter into  any other agreements which  violate the
terms and conditions of this Agreement or  which, after giving effect thereto or
upon  the performance  of any  covenant contained  therein, would  constitute an
Event of  Default or a Potential Event of Default,  or which  would restrict the
ability of one or more Subsidiaries to pay dividends to the Company.

          7.6   Negative Pledge.   The Company  shall not, and shall  not permit
any of its Subsidiaries to, create, incur, assume, permit or suffer to exist 

                                      -26-

<PAGE>

with respect to any of the assets or property of the Company (including, without
limitation,  its  stock  in and  evidences  of debt  from  Subsidiaries)  or any
Subsidiary, or  any income, revenue, or profits therefrom, all whether now owned
or possessed or hereafter acquired, any Lien, assignment, hypothecation, charge,
adverse  claim or  other  encumbrance thereon,  excepting  only Permitted  Liens
(whether or  not the  Company complies with  the last  sentence of  this Section
7.6).   Except  as permitted  by  Section 7.3  and  7.4, the  Company shall  not
transfer  or convey  any of the  assets or  property of the  Company (including,
without  limitation, its  stock  in  Subsidiaries) nor  permit  the transfer  or
conveyance of the assets or property of  any Subsidiary, or any income, revenue,
or profits therefrom, all whether now owned  or possessed or hereafter acquired,
for the purpose,  or with the effect, of  subjecting the same to  payment of any
Debt or other obligation in priority of payment over its general creditors.  The
Company shall not,  and shall not permit  any of its Subsidiaries to,  suffer to
exist any  Debt or obligation which  may, by law, if  unpaid or in the  event of
bankruptcy or  insolvency, or otherwise, be  given priority in payment  over its
general creditors; nor shall the Company or any Subsidiary make any agreement or
arrangement to subordinate the payment of the Notes to any  other Debt.  Without
limiting  the  generality  of  the foregoing,  if  the  Company  or  any of  its
Subsidiaries shall  create, incur,  assume, permit or  suffer to exist  any Lien
(other than Permitted  Liens) upon any of its  or their property or  assets, the
Company shall make or cause to be  made effective provision for the Notes to  be
secured equally and ratably with any Debt secured by such Lien, so long as  such
other Debt  shall be so secured; provided, however,  that, except as provided in
Section 8.1, such Lien shall constitute a  breach of this Section 7.6 regardless
of the Company's compliance with this last sentence.

          7.7   Additional  Subsidiaries.   Prior  to  the  acquisition  of  any
additional  Subsidiary,  the   Company  shall  provide  to   each  Noteholder  a
certificate  from  the chief  financial  officer  or  treasurer of  the  Company
certifying  that  as  of,  and   immediately  after,  the  acquisition  of  such
Subsidiary, the  representations and warranties  contained in Section 5  are and
will be  true and  correct as  to such  Subsidiary and  no Event  of Default  or
Potential  Event  of Default  exists  or,  upon  such acquisition,  will  exist.
Simultaneously  with such  acquisition,  the new  Subsidiary  shall execute  and
deliver to  the Noteholders  an  acknowledgment that  it  is a  "Guarantor"  for
purposes of this  Agreement and  the Note Guarantee,  such acknowledgment to  be
substantially in the form attached to Exhibit 11.44 to this Agreement.

          7.8   Affiliate Transactions.   The Company shall  not, and shall  not
permit  any Subsidiary to enter  into any transaction  with any Affiliate, their
shareholders, the Affiliates of their shareholders, or the executive officers or
directors of any of the foregoing entities unless the same shall be conducted in
the ordinary course of business on an arms' length basis for fair value in 

                                      -27-

<PAGE>

accordance with reasonable  commercial standards and on terms  no less favorable
than those available to third parties generally.

          7.9   Business Practices.  The Company shall not, and shall not permit
its Subsidiaries to,  conduct any line of business which is not related to their
business as conducted on the Closing Date and described in the Private Placement
Memorandum, or if such lines of  business result in a substantial change,  taken
as  a whole,  in the  general  nature of  the business  of the  Company  and its
Subsidiaries in effect on the Closing Date.

          7.10  Restricted Payments.    The Company  shall  not, and  shall  not
permit any of its Subsidiaries to, make any Restricted Payments if:

                (a)   the  cumulative  amount of  such Restricted  Payments made
          after July 29, 1994  would exceed the sum of (i)  $1,000,000; and (ii)
          50%  of Consolidated  Net  Income (or  minus  100% in  the  case of  a
          deficit) computed on a cumulative basis from  July 29, 1994; and (iii)
          net proceeds of  the issuance or sale  of common stock of  the Company
          after July 29, 1994; or

                (b)   at the time of or as a result of, such Restricted Payment,
          any Event of Default would exist; or

                (c)   after  giving  effect  to  such  Restricted  Payment,  the
          Company would not be permitted under the terms of Section 8.2 to incur
          at least $1.00 of additional Total Debt.

Notwithstanding the foregoing,  any Subsidiary may make a  Restricted Payment to
the Company at any time.

          7.11  Investments, Guaranties.  The  Company shall not, and shall  not
permit any of its Subsidiaries to:

                (a)   directly  or indirectly make  or own any  Investment other
          than

                      (i)   Permitted Investments in any Person, and

                      (ii)  additional  Investments  of  the   Company  and  its
                Subsidiaries  in an  aggregate  amount  not  to  exceed  15%  of
                Consolidated Tangible Net Worth; or

                (b)   create  or  become  or  be  liable  with  respect  to  any
          Guarantee except

                      (i)   Guarantees outstanding  on  the date  hereof as  set
                forth in Section 7.11 of Schedule III and

                      (ii)  subject to compliance with  Section 8.2, the Company
                may  become  and   remain  liable  with  respect   to  unsecured
                Guaranties of Debt of any Subsidiary and any other obligation of
                any Subsidiary incurred in the ordinary course of its  business;
                provided  the  maximum  dollar  amount  of  the  Debt  or  other
                obligation  being guaranteed  is  readily  ascertainable by  the
                terms   of  such  obligation  or  the  instrument  or  agreement
                evidencing such Guarantee specifically  limits the dollar amount
                of the maximum liability of the Guarantor thereunder.

          Section 8.  Financial Covenants.   The  Company hereby covenants  with
the Noteholders:

          8.1   Minimum  Tangible Net  Worth.   At  no  time shall  Consolidated
Tangible Net Worth be less than the amounts shown below:

                           Through
     On or After         December 31         Minimum TNW
     July 29, 1994          1994           $ 90.4 million
  January  1, 1995          1995           $ 94.4 million
  January  1, 1996          1996           $ 96.4 million
  January  1, 1997          1997           $ 98.4 million
  January  1, 1998          1998           $100.4 million

  January  1, 2001          2001           $106.4 million


          The Company hereby agrees that in the event  it shall at any time fail
to maintain the Consolidated Tangible Net Worth set forth above, it will execute
and deliver  to the Noteholders  a security agreement, financing  statements and
such  other documents as the Noteholders  may in good faith  require in order to
grant and perfect a security  interest in favor of the Noteholders in  assets of
the Company acceptable to the Noteholders in their sole discretion to secure all
Obligations of  the Company.  Such security interest shall  be pro rata and pari
passu  with any  security interest  granted by  the Company or  its Subsidiaries
under the Bank Financing Documents.

          Upon compliance  with  foregoing obligation  to  grant and  perfect  a
security interest  in its assets, the Company  shall be deemed to  have cured an
Event of Default consisting solely of its failure to maintain its Consolidated 

                                      -29-

<PAGE>

Tangible Net  Worth as  required by this  Section 8.1 so  long as  the Company's
Consolidated Tangible  Net Worth  is not  more than  $3 million  less than  that
required at such time, as set forth above.

          8.2   Total  Debt.  At no time shall Total Debt of the Company and its
Subsidiaries  at  the  end  of  any  Fiscal  Quarter exceed  40%  of  the  Total
Capitalization of the Company and its Subsidiaries.

          8.3   Current  Debt.    The Company's  ratio  of  Consolidated Current
Assets to Consolidated Current Liabilities shall not be less than 1.75 to 1.

          8.4   Fixed  Charge Coverage.  As  of the end  of each Fiscal Quarter,
the Company  and its Subsidiaries  shall have Consolidated Income  Available for
Fixed  Charges of not less than  2.5 times Fixed Charges,  computed on a rolling
four Fiscal Quarter basis.

          of  any  other term,  provision  or  agreement  under which  the  Debt
          described in clause  (i) above was created or governed,  the effect of
          which is to  permit, with the  giving of notice  or lapse of time,  or
