NOTE 6 -- ACQUISITION AND DIVESTITURE

     On April 30, 1998 the Company acquired for approximately
$33.5 million in cash a precipitated calcium carbonate (PCC)
manufacturing facility in the United Kingdom from Rhodia
Limited.  This acquisition allows the Company to establish a
base for its specialty PCC business in Europe.  The transaction
was accounted for as a purchase.  The purchase price exceeded
the fair value of net assets acquired by approximately $8
million, which is being amortized on a straight-line basis over
25 years.

    On April 28, 1998 the Company sold its limestone operation
in Port Inland, Michigan to Oglebay Norton Company for cash and
receivables approximating $34 million.  The sales price was
equivalent to the net book value of the assets.

INDEPENDENT AUDITORS' REPORT



The Board of Directors and Shareholders
Minerals Technologies Inc.:



   We have reviewed the condensed consolidated balance sheet of
Minerals Technologies Inc. and subsidiary companies as of June
28, 1998 and the related condensed consolidated statements of
income for each of the three-month and six-month periods ended
June 28, 1998 and June 29, 1997 and cash flows for the six-
month periods then ended.  These financial statements are the
responsibility of the Company's management. 

  We conducted our review in accordance with standards
established by the American Institute of Certified Public
Accountants.  A review of interim financial information
consists principally of applying analytical procedures to
financial data and making inquiries of persons responsible for
financial and accounting matters.  It is substantially less in
scope than an audit conducted in accordance with generally
accepted auditing standards, the objective of which is the
expression of an opinion regarding the financial statements
taken as a whole.  Accordingly, we do not express such an
opinion.

  Based on our review, we are not aware of any material
modifications that should be made to the condensed consolidated
financial statements referred to above for them to be in
conformity with generally accepted accounting principles.

  We have previously audited, in accordance with generally
accepted auditing standards, the consolidated balance sheet of
Minerals Technologies Inc. and subsidiary companies as of
December 31, 1997, and the related consolidated statements of
income, shareholders' equity, and cash flows for the year then
ended (not presented herein); and in our report dated January
22, 1998, we expressed an unqualified opinion on those
consolidated financial statements.  In our opinion, the
information set forth in the accompanying condensed
consolidated balance sheet as of December 31, 1997 is fairly
presented, in all material respects, in relation to the
consolidated balance sheet from which it has been derived.

RESULTS OF OPERATIONS 

THREE MONTHS ENDED JUNE 28, 1998 AS COMPARED WITH THREE MONTHS
ENDED JUNE 29,1997

   Net sales in the second quarter of 1998 increased 2.6% to
$155.8 million from $151.8 million in the second quarter of
1997. Sales growth from ongoing operations, which exclude the
divested Midwest limestone business, was 6.3%.  The stronger
U.S. dollar had an unfavorable impact of approximately $3.5
million or 2.3 percentage points of sales growth.

   Worldwide sales of Precipitated Calcium Carbonate (PCC),
which is used in manufacturing processes of the paper industry,
grew 16.6% to $85.6 million from $73.4 million in the second
quarter of 1997. This increase was primarily attributable to
the startup of seven new satellite plants since the second
quarter of 1997 and to initial sales to the paper industry from
the acquisition of a specialty PCC business in the United
Kingdom.

   Currently, one PCC satellite facility is under construction,
located in Courtland, Alabama.  This plant, which will be
equivalent to five satellite units, is scheduled to begin
operations during the first half of 1999.  (A "satellite unit"
produces between 25,000 and 35,000 tons of PCC annually.)  The
Company now operates 53 satellite plants in 12 countries
worldwide.

   Beginning in 1998, sales of pyrolytic graphite products,
previously reported in the Processed Minerals product line, are
reported in the Refractory product line.  Prior year's sales
have been reclassified to reflect this change.  Net sales for
the four quarters of 1997 were $1.1 million, $1.0 million, $0.5
million and $0.7 million respectively.

   In April 1998, the Company divested its Midwest limestone
business in Port Inland, Michigan.  References to ongoing
operations exclude the results from this facility.  Net sales
from the Midwest limestone business in the second, third and
fourth quarters of 1997 were $6.4 million, $8.3 million and
$5.9 million, respectively.  Net sales from this facility in
the second quarter of 1998, prior to the divestiture, were $1.3
million.

   Net sales from the ongoing operations of processed mineral
products decreased 4.1% in the second quarter of 1998 to $20.9
million, compared to $21.8 million reported in second quarter
1997.  However, the operating margin as a percentage of sales
showed significant improvement over the second quarter of 1997. 

   Net sales of refractory products, primarily used in the
steel industry, decreased 4.6% in the second quarter of 1998 to
$47.9 million from $50.2 million in the same period last year. 
Foreign exchange had an unfavorable impact of approximately 
$1.8 million on refractory product sales.

   Income from operations rose 15.9% in the second quarter of
1998 to $23.4 million.  This increase was due primarily to
growth in the PCC product line; improved profitability in
refractory products, due primarily to the successful execution
of the Company's strategy of introducing high value innovative
products, and to increased profitability in the processed
minerals product line.
                              Page 10
<PAGE>

   Non-operating deductions increased primarily as a result of
foreign exchange losses in Asia. 

   Net income grew 18.6% to $14.7 million from $12.4 million in
the prior year.  Earnings per common share, on a diluted basis,
were $0.63 as compared to $0.54 in the same period last year.


SIX MONTHS ENDED JUNE 28, 1998 AS COMPARED WITH SIX MONTHS
ENDED JUNE 29, 1997

   Net sales in the first half of 1998 increased 3.6% to $299.9
million from $289.4 million in 1997.  Excluding the effect of
foreign exchange and the divested Midwest limestone business,
sales growth was 8.0%.  This increase was due primarily to the
continued expansion of the PCC product line.  PCC sales
increased 14.7% to $165.1 million compared with $144.0 million
in the first half of 1997.  Worldwide sales from the ongoing
operations of processed mineral products decreased 4.5% to
$39.4 million.  Refractory product sales decreased 3.9% to
$93.7 million compared with $97.5 million in the first half of
1997. This decrease was primarily due to unfavorable foreign
exchange rates.

   Net sales in the United States increased 5.3% in the first
half of 1998 primarily due to the growth in the PCC product
line and solid growth of refractory products.  Net foreign
sales increased approximately 5.9% in the first half of 1998 as
a result of the continued international expansion of the PCC
product line. 

   Income from operations rose 19.3% to $44.5 million in the
first half of 1998 from $37.3 million in the previous year. 

   Non-operating deductions increased primarily as a result of
foreign exchange losses in Asia.

   Net income increased 19.8% to $27.5 million from $22.9
million in 1997.  Diluted earnings per common share were $1.18
as compared with $1.00 for the first six months of 1997.


LIQUIDITY AND CAPITAL RESOURCES

   The Company's financial position remained strong in the
first half of 1998.   Cash flows in the first half of 1998 were
provided from operations and the divested Midwest limestone
business and were applied principally to fund $35.6 million of
capital expenditures, the acquisition of a specialty PCC
business, the repurchase of common shares for treasury and to
remit the required principal payment of $13 million under the
Company's Guarantied Senior Notes due June 11, 2000.  Cash
provided from operating activities amounted to $63.5 million in
the first half of 1998 as compared to $46.5 million in the
prior year. This increase was primarily due to an improvement
in working capital.

   On February 26, 1998, the Company's Board of Directors
authorized a $150 million stock repurchase program under which
the stock will be purchased on the open market from time to
time.  As of July 24, the Company had repurchased approximately
384,000 shares under this program at an average price of
approximately $52 per share.

   On April 28, 1998, the Company sold its limestone operation
in Port Inland, Michigan to Oglebay Norton Company for
approximately $34 million, which was equivalent to its net book
value.  This high volume commodity operation no longer
complemented the Company's long-term strategic vision.  Sales
for the facility were approximately $21 million in 1997.

   On April 30, 1998, the Company acquired for approximately
$33.5 million a PCC manufacturing facility located near
Birmingham in Kings Norton, England from Rhodia Limited, a
specialty chemicals company.  This acquisition will allow the
Company to establish a base for its specialty PCC business in
Europe.  The Company's specialty PCC products are used in food
and pharmaceutical applications, as well as in plastics,
sealants and coatings, and paper.  Sales of this business in
1997 were about $18 million.

   The Company has available approximately $110 million in
uncommitted, short-term bank credit lines, none of which were
in use at June 28, 1998.  The Company anticipates that capital
expenditures for all of 1998 will approximate $90 million,
principally related to the construction of satellite PCC
plants, expansion projects at existing satellite PCC plants,
and other opportunities which meet the strategic growth
objectives of the Company.  The Company expects to meet such

                            Page 11
<PAGE>

requirements from internally generated funds, the
aforementioned uncommitted bank credit lines and, where
appropriate, project financing of certain satellite plants.


PROSPECTIVE INFORMATION AND FACTORS THAT MAY AFFECT FUTURE
RESULTS

   The Securities and Exchange Commission encourages companies
to disclose forward-looking information so that investors can
better understand a company's future prospects and make
informed investment decisions.  This report may contain such
forward-looking statements that set out anticipated results
based on management's plans and assumptions.  Words such as
"anticipate," "estimate," "expects," "projects," and words and
terms of similar substance used in connection with any
discussion of future operating or financial performance
identify these forward-looking statements.

   The Company cannot guarantee that any forward-looking
statement will be realized, although it believes it has been
prudent  in its plans and assumptions.  Achievement of future
results is subject to risks, uncertainties and inaccurate
assumptions.  Should known or unknown risks or uncertainties
materialize, or should underlying assumptions prove inaccurate,
actual results could vary materially from those anticipated,
estimated or projected.  Investors should bear this in mind as
they consider forward-looking statements and should refer to
the discussion of certain risks, uncertainties and assumptions
under the heading "Cautionary Factors That May Affect Future
Results" in Item 1 of the Company's Annual Report on Form 10-K
for 1997.

RECENTLY ISSUED ACCOUNTING STANDARDS

   In February 1998, the Financial Accounting Standards Board
issued SFAS No. 132, "Employers' Disclosure about Pensions and
Other Postretirement Benefits," which revises employers'
disclosures about pension and other postretirement benefit
plans.  It does not change the measurement or recognition of
those plans.  The statement is effective for fiscal years
beginning after December 15, 1997.  The adoption of this
statement has no impact on the consolidated financial
statements.

   In March 1998, the American Institute of Certified Public
Accountants issued Statement of Position 98-1 ("SOP 98-1"),
"Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use."  The statement is effective for
fiscal years beginning after December 15, 1998.  Earlier
application is encouraged in fiscal years for which annual
financial statements have not been issued.  The statement
defines which costs of computer software developed or obtained
for internal use are capitalized and which costs are expensed. 
The Company adopted SOP 98-1 in 1998.  The adoption of SOP 98-1
does not materially affect the consolidated financial
statements.

   In April 1998, the American Institute of Certified Public
Accountants issued Statement of Position 98-5 ("SOP 98-5"),
"Reporting on the Costs of Start-Up Activities."  The statement
is effective for fiscal years beginning after December 15,
1998.  The statement requires costs of start-up activities and
organization costs to be expensed as incurred.  The Company
will adopt SOP 98-5 for calendar year 1999.  The adoption of
SOP 98-5 will not materially affect the consolidated financial
statements.

   In June 1998, the Financial Accounting Standards Board
issued SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities."  The statement establishes accounting and
reporting standards for derivative instruments and for hedging
activities.  It requires that an entity recognize all
derivatives as either assets or liabilities in the statement of
financial position and measure those instruments at fair value. 
The statement is effective for all fiscal quarters of fiscal
years beginning after June 15, 1999.  The Company will adopt
SFAS 133 by January 1, 2000.  Adoption of SFAS 133 is not
expected to have a material effect on the consolidated
financial statements.

YEAR 2000 CONVERSION

   Management has initiated an enterprise-wide program to
improve the capability of the current information systems and
to prepare the Company's computer systems and applications for
the year 2000.  The Company is presently in the midst of
installing systems which are year 2000-compliant and will
replace the majority of the legacy information technology
systems and applications.  It is anticipated that such systems
will be installed by the middle of 1999. The Company does not
expect 
                        Page 12
<PAGE>

the total cost of the year 2000 conversion to have a material
adverse effect on the Company's future results of operations
and financial condition.

               PART II.  OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS
     The Company and its subsidiary Specialty Minerals Inc. are
defendants in a lawsuit, captioned EATON CORPORATION V. PFIZER
INC, MINERALS TECHNOLOGIES INC. AND SPECIALTY MINERALS INC.,
which was filed on July 31, 1996 and is pending in the U.S.
District Court for the Western District of Michigan.  The suit
alleges that certain materials sold to Eaton for use in truck
transmissions were defective, necessitating repairs for which
Eaton now seeks reimbursement.  While all litigation contains
an element of uncertainty, the Company and Specialty Minerals
Inc. believe that they have valid defenses to the claims
asserted by Eaton in this lawsuit, are continuing to vigorously
defend all such claims, and believe that the outcome of this
matter will not have a material adverse effect on the Company's
consolidated financial position or results of operations.

     The Company and its subsidiaries are not party to any
other material pending legal proceedings, other than ordinary
routine litigation incidental to their businesses.

the terms of this Agreement or by any act, thing, omission or means 
whatever which, but for this provision, might operate to exonerate or 
discharge the Guarantor from its obligations under the guarantee and 
indemnity contained in this Clause 7.

7.5	The Guarantor's obligation hereunder shall be as primary obligor 
and not merely as surety and accordingly (and for the avoidance of 
doubt):-

first against the Vendor before making any or any alleged claim 
hereunder against the Guarantor;

7.5.2	each defence, set-off or counterclaim which would have been 
available to the Vendor shall likewise be available to the Guarantor 
to the extent that the same has not been exhausted by the Vendor;

7.5.3	the Guarantor hereby waives notice to it of any amendment 
or modification of this Agreement (other than to this Clause 7) 
made between the Purchaser and the Vendor; and

7.5.4	no time, waiver or other indulgence granted by any Party 
to the other, and no change in the corporate existence or identity 
of the Vendor shall in any way impair, negative or reduce the 
Guarantor's obligation hereunder.

(b) with respect to all other Claims, the second anniversary of

circumstances of any Claim; and

Sellers to inspect, survey or audit any thing, site or record and 
to give the Sellers access to any of the Purchaser's personnel as 
may be reasonably necessary in the circumstances and co-operate to 
enable the Sellers to bring or defend any proceedings in connection 
with any such Claim and in any event not to make any admission of 
liability in or otherwise to compromise any Claim with respect of 
any third party.

8.3	The maximum joint aggregate liability of the sellers to the 
Purchaser in respect of any and all Claims, is hereby limited to a 
sum equivalent to two thirds of the aggregate of the Consideration.

8.4	The Purchaser shall not bring any Claim in respect of any 
Warranty unless such individual claim exceeds 50,000 pounds sterling 
and until the aggregate of such claims exceeds 250,000 pounds sterling. 
These amounts are not intended to establish the standard of materiality 
under this Agreement.

8.5	Any amounts paid by either Seller in respect of any Claim shall 
be treated as a pound for pound reduction in the Consideration.

8.6	To the extent that the circumstances underlying any Claim are 
capable of being remedied then the Purchaser shall afford the Sellers 
a reasonable opportunity to remedy the same (which shall not however 
extend beyond 90 days after notice is given pursuant to Clause 8.1).

8.7	The Sellers shall not be liable in respect of any Claim to the 
extent that:-

8.7.1	the Purchaser caused or contributed to the same or to the acts 
and/or omissions giving rise to such Claim; and

8.7.2	the matter to which it relates is fully and promptly made good 
by the Sellers without cost to the Purchaser.

if and to the extent that the facts or information upon which the Claim 
is based are fairly disclosed in the Disclosure Letter.

of any Claim based on a contingent liability of the Purchaser unless and 
until the liability of the Purchaser becomes an actual liability.

and to the extent that it arises or is increased as a result of an 
increase in rates of taxation after Completion, or the passing of 
any legislation (or making of any subordinate legislation) with 
immediate or retrospective effect.

8.11	The Sellers shall have no liability in respect of any Claim to 
the extent that it relates to any loss for which the Purchaser is 
indemnified by insurance.

8.12	The Sellers shall have no liability in respect of any Claim to 
the extent that the circumstances, facts or events giving rise to 
the Claim would have been readily apparent to the Purchaser by 
virtue of the investigations into the Assets or the Site carried 
out on behalf of the Purchaser prior to the Completion Date.

8.13	Where the Purchaser is entitled to recover from some other 
person any sum in respect of any matter or event which could give 
rise to a Claim the Purchaser shall take all appropriate steps to 
recover that sum before making such Claim, and any sum recovered 
will reduce the amount of such Claim (and, in the event of the 
recovery being delayed until after such Claim has been satisfied 
by the Sellers, the sum recovered will be paid to the Sellers, 
after deduction of all reasonable costs and expenses of the recovery).

8.14	The Purchaser hereby relinquishes and waives any right of 
set-off or counter-claim, deduction or retention which the Purchaser 
might otherwise have in respect of any Claim or out of any payments 
which the Purchaser may be obliged to make (or procure to be made) 
to the Sellers (or any of them) pursuant to this Agreement or otherwise.

8.15	The Purchaser's sole remedy in respect of any Claim (other than 
any arising under Clause 6 or Clause 10) shall be damages.

8.16	In the event Completion does not occur (for whatever reason other 
than the refusal by a party to do so in circumstances where all 
conditions to Completion set out in Clause 3.12 have been satisfied 
or waived by the other parties), then it is agreed and acknowledged 
that no party shall have any liability to any other party whether 
for damages or otherwise.

the Sellers arising prior to the Completion Date whether arising in

13.2	The Parties agree to co-operate and negotiate with each other 
in good faith between exchange of this Agreement and Completion in 
order to put arrangements in place to facilitate a smooth and efficient 
transfer of the Business from the Sellers to the Purchaser.  It is

13.2.1	the agreement on applicable terms and conditions in 
respect of pensions; and

13.2.2	the negotiation of a contract for the provision of 
services by the Vendor to the Purchaser after Completion.

reasonable endeavours to give or procure to be given to the Purchaser

with the Sellers in connection with the Business announcing the transfer 
to the Purchaser of the Business and the Assets. 

13.7	Pension Arrangements

13.7.1	the Vendor and the Purchaser shall, before the Completion, 
use their respective reasonable endeavours to agree the pension terms 
applicable to those Employees who are, immediately before April 5, 1998, 
contributory members of the Pension Scheme ("the Relevant Members");

13.7.2	the Purchaser shall establish or nominate a pension scheme 
("the Purchaser's Plan") on no less favorable terms than the Minteq UK 
Pension Plan details of which have been provided to the Sellers and 
invite relevant Members to join the Purchaser's Plan for future service;

13.7.3	the Vendor and the Purchaser shall each use their 
best endeavours:

and

form setting out the amount which will enable the Purchaser's Plan to 
pay benefits to those Relevant Employees who enroll in the Purchaser's 
Plan, taking into account the effect of the past service of Relevant 
Members on the amount of future benefits.  The actuaries shall disclose 
the assumptions on which the calculation of such transfer amount is based.

The enrollment of Relevant Members in the Purchaser's Plan will include 
a credit for past service benefits, provided that a transfer is made 
from the trustees of the Pension Scheme to the trustees of the 
Purchaser's Plan in respect of that past service on the basis agreed 
by the actuaries of the Sellers and the Purchasers.

Such transfer will not entail any additional expense to the Sellers

no obligation to pay any amount in excess of contributions required 
to be made pursuant to the rules of the Pension Scheme.

13.8	The Sellers shall, within 15 business days after Completion

changed so as not to include the word "Sturge" or any confusingly 
similar word or name.

14.	GENERAL

14.1	The Purchaser shall account to the Inland Revenue for

Value Added Tax Act 1994 and Article 5 of the Value Added Tax

on them.  The Sellers and the Purchaser shall each promptly following 
Completion inform their respective VAT Offices of the sale and purchase 
under this Agreement, complete all relevant forms for VAT purposes 
relating to such sale and purchase and take all reasonable steps to 
ensure that the sale of the Assets is treated neither as a supply of 
goods nor a supply of services for the purposes of VAT but as the 
transfer of a going concern.  In the event that it is at any time 
etermined by H. M. Customs & Excise or, on appeal, by the Tribunal or 
the Court that Section 49 of the Value Added Tax Act 1994 and Article 5 
of the Value Added Tax (Special Provisions) Order 1995 do not apply to 
the sale of the Assets or the Site or any part of them, the Purchaser 
shall pay to the Vendor or the Guarantor (as the case may be), the 
amount of the VAT in question on the later of the business day before 
such amount is due to be paid by the relevant Seller to Customs & Excise 
and the day on which the relevant Seller delivers to the Purchaser, 
a valid VAT invoice or invoices in respect thereof.

14.4	The Purchaser undertakes to keep all of the Documents which 
relate to the tax and accounting affairs of the Business secure and 
complete for not less than six years after the Completion Date and to 
allow the Sellers access to them at all reasonable times during this 
period for the purposes of inspection and to take copies thereof 
where necessary.

14.5	The Parties shall do and give all such deeds and further 
assurances as may be reasonable to give effect to each of the 
assignments and transactions contemplated herein (the costs of 
the preparation, execution and filing of all such deeds and assurances 
and any registrations, filings and notifications with or to any 
regulatory body to be borne by the Purchaser).

14.6	Save as is expressly provided otherwise, each Party shall bear 
its own costs in connection with the negotiation or preparation or 
completion of this Agreement.

14.7	Each Party unconditionally waives any rights it may have to 
claim damages against the other on the basis of any written or oral 
statement made by the other (whether made carelessly or not) not set 
out or referred to in this Agreement (or for breach of any warranty 
given by the other not so set out or referred to) unless such statement 
or warranty was made or given fraudulently or with a reckless disregard 
for its truthfulness.

14.8	Each Party unconditionally waives any rights it may have to 
rescind or to seek to rescind this Agreement on the basis of any 
written or oral statement made by the other (including any Warranty) 
(whether made carelessly or not) whether or not such statement is set 
out or referred to in this Agreement unless such statement was made 
fraudulently or with a reckless disregard for its truthfulness.

14.9	The parties agree to execute, complete and keep the original 
and all executed counterparts of this Agreement outside the 
United Kingdom at all times, except that a Party shall be entitled 
to bring the original or counterpart into the United Kingdom where:

(i)	it is a mandatory legal requirement to produce the document 
in any judicial or arbitration proceedings:

(ii)	the document is to be used as evidence in legal or arbitration 
proceedings and the judge or arbitrator responsible for the 
determination of the proceedings has ruled that a certified 
copy cannot be produced as adequate evidence; or

(iii)	the document is required by the Inland Revenue or HM Customs 
to determine the liability of either of the Sellers to taxation 
arising from the execution of the document or performance of the Agreement.

PROVIDED ALWAYS that the Sellers shall use all reasonable efforts to 
procure the agreement of the person or authority requiring production 
of the document to accept a certified copy in its place.
		
15.	JURISDICTION

15.1	The Parties hereby submit to the exclusive jurisdiction of the 
English Courts but without prejudice to the enforcement or execution 
of any judgment, order or award thereof, or to any interlocutory or 
injunctive proceedings in any other jurisdiction.  This Clause 15.1 
is without prejudice to Clause 15.3.

15.2	For the purposes of Order 10, Rule 3, Rules of the Supreme Court 
(or any modification thereof), the Parties agree that any process or 
other legal proceedings may be served on any of them by leaving a copy 
thereof or by posting a copy thereof addressed to a Party at its 
address first stated above.

15.3	The Parties hereby agree that they shall use their reasonable 
endeavours to seek to settle any dispute and to negotiate the same 
in good faith prior to instituting any proceedings.

15.4	Any notice permitted or required to be given under this 
Agreement shall be in writing and shall be given, posted, delivered 
or transmitted to the Party at the addresses first written above,

  determination of the Purchase Price pursuant to Section
  IV(D)(1) of this Agreement.  If the Purchase Price, as

  this Agreement, is less than the Estimated Purchase Price,
  Seller shall pay Buyer an amount equal to the difference
  between the Estimated Purchase Price and the Purchase Price
  as finally determined, which amount shall be paid by wire
  transfer to an account designated by Buyer within three (3)
  business days after the final determination of the Purchase
  Price pursuant to Section IV(D)(1) of this Agreement.

  V. REPRESENTATIONS AND WARRANTIES OF SELLER
  
  The term "Disclosure Schedule" as used in his Agreement means

  concurrently with the execution and delivery of this
  Agreement.   Except as set forth in the Disclosure Schedule,
  Seller represents and warrants to Buyer that, as of the date
  of this Agreement and on the Closing Date:
  
     A.   DUE INCORPORATION.
  
  Seller is a corporation duly organized, validly existing and
  in good standing under the laws of the State of Michigan and
  has all requisite corporate power and authority to own or
  lease the Included Assets in the places where such assets are
  now owned or leased. Seller has all necessary corporate power
  sufficient to enable it to enter into, perform, and carry out
  the transactions contemplated by this Agreement.
  
     B.   AUTHORIZATION.
  
  No authorization or approval or other action by, and no
  notice to or filing with, any governmental authority or
  regulatory body is required for the due execution, delivery
  and performance of this Agreement, other than the 
  Hart-Scott-Rodino filing referred to in Section VII(M) of this
  Agreement.
  
     C.   TITLE.
  
  Seller has, and will convey to Buyer or its nominee, good and
  marketable title in fee simple to the Real Property (other
  than leased Real Property), free and clear of all interests,
  claims, liens and encumbrances, with no title defects
  whatsoever other than Permitted Encumbrances.  Seller has the
  corporate power and authority to sell, transfer, assign or
  convey, as the case may be, such Real Property.  As used in
  this Agreement, "Permitted Encumbrances" means:  those
  matters listed on Schedule I(A)(6); zoning, building or other
  restrictions, variances, easements and rights-of-way, none of
  which, individually or in the aggregate:  (A) interfere with
  or impair in any material respect the present use of the Real
  Property, (B) have more than an insignificant effect on the
  value thereof or its present use, or (C) would impair the
  ability of Buyer to sell the Real Property for its present
  use; and taxes on Real Property not yet due and payable. 
  Seller has, and will convey to Buyer or its nominee, good and
  marketable title to, and has the corporate power and
  authority to sell, transfer, assign or convey, as the case
  may be, the Included Assets (other than owned Real Property),
  free and clear of all liens, leases, pledges, charges,
  claims, encumbrances, security interests and equities.  As of
  the Closing Date, there will be no mortgage, trust deed,
  chattel mortgage, conditional sale agreement, security
  agreement, financing statement or other instrument
  encumbering any of the Included Assets except for Permitted
  Encumbrances.  There are no contracts, restrictions, liens,
  claims or encumbrances which will prevent Seller from giving
  to Buyer possession of the Included Assets or which will
  limit in any way Buyer's ability, in accordance with its
  ownership interest, to use, sell, or in any way handle, use
  or dispose of said assets.
  
     D.   LIMESTONE AND DOLOMITE RESERVES.
  
  To the best of Seller's knowledge, the written information
  with respect to Limestone and Dolomite reserves attached
  hereto as Exhibit V(D) is a reasonable estimate of such
  reserves located on or under the Real Property and to which a
  fee interest, leasehold interest, mineral right, or other
  right of exploitation in good standing will be transferred to
  Buyer as provided in this Agreement.

  normal wear and tear excepted.
  
     G.   CERTAIN CLAIMS.

  Seller's knowledge, no event, occurrence or condition has
  occurred (or is threatened to occur) which, with the lapse of
  time, the giving of notice, or the happening of any further

  purposes at all reasonable times during normal business
  hours, for a seven-year period after the Closing Date.  As
  used in this paragraph, the right of inspection includes the

  party desiring to destroy records shall permit the other
  party to make reasonable arrangements to preserve or
  duplicate such records.

  Buyer shall offer employment as of the Closing Date to all
  employees of Seller's Business on the date immediately prior
  to the Closing Date, including any employees on vacation, but
  not any employees on short-term disability, worker's
  compensation,  long-term disability or leave of absence
  (hereinafter, "Employees" or, individually, "Employee"). 
  Such offer of employment to each Employee shall be at a rate
  of pay at least equal to such Employee's base rate of pay in

  Buyer shall review the benefits provided by Seller to such
  Employees prior to the Closing Date and shall provide such
  Employees with benefits from and after the Closing Date of
  the types and in the amounts which Buyer provides to other
  similarly situated employees of Buyer.  Prior to the

  listing of the current rates of pay, positions and dates of
  hire of the Employees. Buyer shall have no obligation
  whatsoever with regard to any persons who are not Employees
  or to Employees who do not accept Buyer's offer of
  employment.  Buyer shall be solely responsible for all
  salaries or wages and benefits accruing on or after the
  Closing Date. In the event Buyer terminates any Employee's
  employment with Buyer other than for cause within six (6)
  months after the Closing Date, Seller shall provide
  termination payments to such Employee in an amount equal to
  such Employee's then-current weekly rate of pay multiplied by
  such Employee's combined years of service with Seller and
  Buyer.  Seller shall retain the responsibility for, and
  indemnify, defend and hold Buyer harmless, against, all
  liabilities, claims and obligations of and to Employees,
  reported or unreported, which arise or accrue prior to the

  and the conditions thereof, employee welfare benefit plans of

  warranties extended by Seller prior to Closing and shall
  promptly inform Seller of any complaints or claims made with
  respect to such warranties.  All such warranties shall remain
  the obligation of Seller, and Seller shall defend, indemnify
  and hold harmless Buyer against any loss, damage or expense
  relating to the same, provided that Buyer shall have complied
  with the requirement of notice and cooperation set forth in
  Section VII(I).  Buyer shall have the benefit of any express
  or implied warranties from the manufacturer or original
  seller of the Included Assets if the same is available to a
  transferee pursuant to the terms of the warranty, and Seller
  shall take all actions necessary and execute such instruments
  as are necessary to effect the transfer of the warranty.

  Business, provided that the party requesting cooperation
  shall reimburse the other party for the other party's
  reasonable out-of-pocket costs and expenses of furnishing
  such cooperation.  In the event Seller is required by law to
  mitigate impacts at the Facilities relating to Seller's
  operations, Buyer shall allow Seller to conduct such
  mitigation at the Facilities provided that Seller shall not
  unreasonably interfere with Buyer's ongoing or reasonably
  anticipated future mining operations.

  Closing Date.  Notwithstanding anything to the contrary in
  this Agreement, Seller agrees to indemnify, defend and hold
  harmless Buyer for any loss or liability incurred by Buyer
  because of the failure to comply with the bulk sales laws of
  any state.
  
     K.   NOTICE;  BEST  EFFORTS TO  CONSUMMATE TRANSACTION.
  
  Each party shall promptly give the other party written notice
  upon its discovery of the existence or occurrence of any
  condition which would make any representation or warranty
  herein contained of either party untrue or which might
  reasonably be expected to prevent the consummation of the
  transactions herein contemplated. Neither Buyer nor Seller
  shall intentionally perform any act which, if performed, or
  omit to perform any act which, if omitted to be performed,
  would prevent or excuse the performance of this Agreement by
  Buyer or Seller or which would result in any representation
  or warranty herein contained being untrue in any material
  respect.

  of (i) any product liability claims made against Seller or
  Seller's Business resulting solely from any Products that are
  shipped from the Facilities at any time after the Closing or
  (ii) Buyer's failure to honor, discharge, pay or fulfill any
  liabilities or obligations assumed by Buyer in this
  Agreement.
  
     C.   NOTICE OF INDEMNIFICATION.
  
  In the event any legal proceeding or investigation shall be
  threatened or instituted or any claim or demand shall be
  asserted by any person in respect of which payment may be
  sought by one party hereto from the other party under the
  provisions of this Section XII (hereinafter, "Claim"), the
  party seeking indemnification (the "Indemnitee") shall
  promptly cause written notice of the assertion of any such
  Claim of which it has knowledge and which is covered by this
  indemnity to be forwarded to the other party (the
  "Indemnitor"), which notice must be received by the
  Indemnitor prior to the expiration of twenty-seven (27)
  months after the Closing Date (except for indemnification
  sought pursuant to Section XII(A)(3), Section XII(A)(4),
  Section XII(A)(5) or Section XII(B)3).  Any such notice shall
  state specifically the provision of this Agreement with
  respect to which the Claim is made, the facts giving rise to
  such Claim, and the amount of the liability asserted against
  the Indemnitor by reason of the Claim.
  
     D.   INDEMNIFICATION PROCEDURE FOR THIRD-PARTY CLAIMS.
  
  In the event of the initiation of any legal proceeding
  against an Indemnitee by a third party, the Indemnitor shall
  have the absolute right after the receipt of notice, at its
  option and at its own expense, to engage counsel of its
  choice and to defend against, negotiate, settle, (but not
  without the prior consent of Indemnitee which consent shall
  not be unreasonably withheld) or otherwise deal with any
  proceeding, claim, or demand which relates to any loss,
  liability, or damage indemnified against hereunder, and the
  Indemnitee shall cooperate fully with the Indemnitor.
  
     E.   EXCLUSIVE REMEDY.
  
  Except as is otherwise specifically set forth in this
  Agreement, the exclusive remedy available to a party hereto
  in respect of a breach by the other party of its obligations
  under this Agreement shall be to proceed in the manner set
  forth in this Section XII and subject to the limitations set
  forth herein.  Notwithstanding anything else in this
  Agreement to the contrary, the limitations of Section
  XII(A)(1) and the provisions of this Section XII(E) shall not
  apply to any breach of Seller's warranties set forth in the
  Warranty Deeds referred to in Section I(D)b.
  
     F.   RESPONSIBILITY UNDER CERTAIN ENVIRONMENTAL LAWS.
  
  No provision of this Agreement shall limit or otherwise
  restrict any liability or responsibility of either party to
  the other or in any manner under or in connection with the
  Comprehensive Environmental Response, Compensation and
  Liability Act, as amended, 42 USC 9601, et seq., the Resource
  Conservation and Recovery Act of 1976, as amended, 42 USC
  6901, et seq., and Parts 111 and 303 of the Michigan Natural
  Resources and Environmental Protection Act.
  
     G.   ARBITRATION.
  
  Each party agrees that to the extent any dispute arising in
  connection with this Agreement is not resolved by voluntary
  agreement of the parties, such dispute shall be finally and
  exclusively settled by arbitration in accordance with the
  provisions of this Section XII(G).  If any such dispute
  arises, either party may at any time deliver written notice
  that it intends to submit such dispute to arbitration.  If
  such a notice is delivered to the other party, then the party
  that delivered such notice shall be entitled to direct
  submission of the dispute to arbitration.  The party
  directing a submission to arbitration shall promptly deliver
  written notice to the other party.  Notwithstanding this
  Section XII(G), each party shall have the right to seek from
  any court of competent jurisdiction pending the establishment
  of the arbitral tribunal interim relief in aid of arbitration
  or to protect the rights of such party in respect of this
  Agreement.  Any request for such interim relief by a party
  shall not be deemed incompatible with, or a waiver of, this
  agreement to arbitrate.  Such arbitration shall be held in
  Detroit, Michigan (which shall be the exclusive location of
  such arbitration unless otherwise agreed by the parties) in
  accordance with the commercial arbitration rules and
  regulations of the American Arbitration Association, with
  pre-hearing discovery rights in accordance with the Federal
  Rules of Civil Procedure.  The determination of the
  arbitrators shall be conclusive and binding upon the parties,
  and any determination by the arbitrators of an award may be
  filed with the clerk of a court of competent jurisdiction as
  a final adjudication of the claim involved, where application
  may be made to such court for a judicial acceptance of the
  award and an order of enforcement, as the case may be.  The
  expenses of each party, including legal and accounting fees,
  if any, with respect to the arbitration, shall be borne by
  such party, except to the extent otherwise directed by the
  arbitrators.  The arbitrators shall designate the parties to
  bear the expenses of the arbitrators of the respective
  amounts of such expense to be borne by each party.
  
  XIII.   TERMINATION: RIGHT TO DAMAGES
  
  If this Agreement is terminated pursuant to its terms,
  neither party hereto shall have any claim against the other
  except if the circumstances giving rise to such termination
  were caused by the other party's willful breach of any
  covenant or agreement in this Agreement, by a representation
  known by such other party to be false when made, or by a
  closing document delivered by such other party being
  knowingly incorrect when delivered; in which events such
  termination shall be in violation of this Agreement and shall
  not be deemed or construed as limiting or denying any legal
  or equitable right or remedy of said party.
