     NOTES TO FINANCIAL STATEMENTS (Unaudited)
     GEORGIA-PACIFIC CORPORATION
     SEPTEMBER 30, 1995


     1.   PRINCIPLES OF PRESENTATION.  The interim financial information
          included herein is unaudited; however, such information reflects all
          adjustments which are, in the opinion of management, necessary for a
          fair presentation of the Corporation's financial position, results
          of operations and cash flows for the interim periods. All such
          adjustments are of a normal, recurring nature.  Certain 1994 amounts
          have been reclassified to conform with the 1995 presentation.

     2.   CASH AND CASH EQUIVALENTS.  At September 30, 1995, the Corporation
          had invested approximately $366 million in marketable securities.
          When the securities matured on October 5, 1995, the proceeds were
          used to reduce short-term borrowings.

     3.   INCOME (LOSS) PER SHARE.  Income (loss) per share is computed based
          on net income (loss) and the weighted average number of common
          shares outstanding, net of restricted shares.  The effects of
          assuming issuance of common shares under long-term incentive, stock
          option and stock purchase plans were either insignificant or
          antidilutive.

     4.   ACCOUNTING CHANGE.  Effective January 1, 1994, the Corporation
          adopted Financial Accounting Standard Number 112 (FAS 112),
          "Employers' Accounting for Postemployment Benefits."  FAS 112
          requires accrual-basis recognition of benefits provided by an
          employer to former or inactive employees after employment but before
          retirement.  The adoption of FAS 112 resulted in a one-time, after-
          tax charge of $5 million (6 cents per share) in the 1994 first
          quarter.

     5.   OTHER INCOME. In the 1994 first quarter, the Corporation recorded
          other pretax income of $57 million ($34 million after taxes),
          primarily resulting from the sales of its roofing  manufacturing and
          envelope businesses.

     6.   EXTRAORDINARY ITEM. The Corporation called for redemption
          approximately $204 million of its outstanding debt during the 1994
          first quarter.  As a result, an after-tax extraordinary loss of $11
          million (12 cents per share) was recognized.

     8.   INVENTORY VALUATION.  Inventories include costs of material, labor
          and plant overhead.  The Corporation uses the dollar value pool
          method for computing LIFO inventories.  The major components of
          inventories were as follows:

     9.   PROVISION FOR INCOME TAXES.  The Corporation reported pretax income
          of $540 million and an income tax provision of $216 million for the
          three months ended September 30, 1995.  The Corporation reported
          pretax income of $151 million and an income tax provision of $64
          million for the three months ended September 30, 1994.  The
          Corporation reported pretax income of $1.4 billion and an income tax
          provision of $548 million for the nine months ended September 30,
          1995.  Excluding asset sales, the Corporation reported pretax income
          before extraordinary item and accounting change of $225 million and
          an income tax provision of $102 million for the nine months ended
          September 30, 1994.  The actual effective rate for these periods was
          different than the federal statutory tax rate primarily because of
          nondeductible goodwill amortization expense.


     10.  COMMITMENTS AND CONTINGENCIES.  The Corporation is a party to
          various legal proceedings incidental to its business and is subject
          to a variety of environmental and pollution control laws and
          regulations in all jurisdictions in which it operates.  As is the
          case with other companies in similar industries, the Corporation
          faces exposure from actual or potential claims and legal proceedings
          involving environmental matters.  The Corporation is self-insured
          for general liability claims up to $5 million per occurrence.
          Liability insurance in effect during the last several years provides
          coverage for environmental matters only to a limited extent.

          The Corporation is involved in environmental remediation activities
          at numerous sites where it has been notified that it is or may be a
          potentially responsible party under the Comprehensive Environmental
          Response, Compensation and Liability Act or similar state
          "superfund" laws and at certain of its own properties.  Of the
          known sites in which it is involved, the Corporation estimates that
          approximately 45 percent are being investigated, approximately 40
          percent are being remediated and approximately 15 percent are being
          monitored (an activity which occurs after either site investigation
          or remediation has been completed).  The ultimate costs to the
          Corporation for the remediation of many of these sites cannot be
          predicted with certainty due to the often unknown magnitude of the
          pollution or the necessary cleanup, the varying costs of alternative
          cleanup methods, the amount of time necessary to accomplish such
          cleanups, the evolving nature of cleanup technologies and government
          regulations and the inability to determine the Corporation's share
          of multi-party cleanups or the extent to which contribution will be
          available from other parties.  The Corporation has established
          reserves for environmental remediation costs for these sites in
          amounts which it believes are probable and reasonably estimable. 

<PAGE>   7
          Based on analysis of currently available information and
          previous experience with respect to the cleanup of hazardous
          substances, the Corporation believes that it is reasonably possible
          that costs associated with these sites may exceed current reserves by
          amounts that may prove insignificant or that could range, in the
          aggregate, up to approximately $ 81 million.  This estimate of the
          range of reasonably possible additional costs is less certain than
          the estimates upon which reserves are based, and in order to
          establish the upper limit of such range, assumptions least favorable
          to the Corporation among the range of reasonably possible outcomes
          were used.  In estimating both its current reserve for environmental
          remediation and the possible range of additional costs, the
          Corporation has not assumed it will bear the entire cost of
          remediation of every site to the exclusion of other known potentially
          responsible parties who may be jointly and severally liable.  The
          ability of other potentially responsible parties to participate has
          been taken into account, based generally on the parties' financial
          condition and probable contribution on a per site basis.

          In the fourth quarter of 1992, the Corporation filed suit in the
          State of Washington against numerous insurance carriers for coverage
          under comprehensive general liability insurance policies issued by
          those carriers.  The Corporation sought a declaratory judgment to
          the effect that past and future environmental remediation and other
          related costs with respect to certain of the sites are covered by
          such policies.  The Corporation has now dismissed or settled its
          claims against all but one of those carriers for a total of
          approximately $54 million.  Approximately $32 million of this amount
          has been received ($28 million of which was recorded as pretax
          income in 1995) and the remainder is payable, subject to certain
          contingencies, over approximately the next ten years.  No amounts
          have been recorded for contingent payments.

          The Corporation has received and responded to three comprehensive
          information requests from the Environmental Protection Agency (EPA)
          concerning air emissions at approximately 30 of the Corporation's
          facilities which manufacture oriented strand board, medium-density
          fiberboard, plywood and particleboard.  On August 5, 1994, the EPA
          issued a Notice of Violation (NOV) with respect to alleged
          violations of certain requirements of the Clean Air Act at these
          facilities relating to, among other things, alleged emissions of
          volatile organic compounds from sources constructed or modified
          since 1980.  The Corporation is in the process of negotiating a
          resolution of the allegations contained in the NOV with the EPA and
          the state environmental agencies involved.  Any settlements would
          entail the payment of fines and agreement by the Corporation to
          install air emission control equipment at certain of these
          facilities.

          Approximately 220 suits involving 9,160 plaintiffs are currently
          pending in several state courts in Mississippi.  The suits allege a
          variety of torts including nuisance, trespass and infliction of
          emotional distress primarily related to the alleged discharge of
          dioxin into the Leaf River from a pulp mill owned by a subsidiary of
          the Corporation.  Three of these cases have been tried.  A total of
          $241,000 in compensatory damages and $4 million in punitive damages
          were awarded to three plaintiffs in the first two cases (Simmons and
          Ferguson) with respect to certain claims.  The jury found in favor
          of the Corporation with respect to a fourth plaintiff.  The
          Corporation appealed both judgments.  On July 8, 1993, in the third
          Mississippi dioxin case tried, the jury returned a verdict in favor
          of the Corporation on all counts (Beech/Williams).  The plaintiffs
          have appealed.  In early 1994 two dioxin cases pending in federal
          court in Mississippi were voluntarily dismissed with prejudice by
          the plaintiffs.

<PAGE>   8


          On October 19, 1995, the Mississippi Supreme Court reversed the
          judgment in the Ferguson case.  In Ferguson, compensatory damages of
          $200,000 and punitive damages of $3,000,000 were assessed against
          the Corporation.  The Mississippi Supreme Court ruled that the
          plaintiffs failed to prove that the defendants had caused any
          emotional distress or created a nuisance with respect to the
          plaintiffs' properties.  The Court also ruled that the plaintiffs
          had failed to show that the defendants' conduct constituted
          intentional, willful, wanton or grossly negligent behavior.  The
          Court reversed the lower court verdict and ordered judgment for the
          defendants.  No decisions have been issued by the Mississippi
          Supreme Court in the other cases on appeal, Simmons and
          Beech/Williams.

          Although there can be no assurances as to the ultimate outcome of
          the approximately 220 suits pending against the Corporation for
          alleged discharges of dioxin, however, based on the decision of the
          Mississippi Supreme Court in the Ferguson case the Corporation
          believes it has valid defenses to the remaining lawsuits.  Suit has
          been filed against the mill's insurance carriers seeking a
          declaratory judgment to the effect that these dioxin claims are
          covered by various insurance policies issued to the Corporation.

          The Corporation and many other companies are defendants in suits
          brought in various courts around the nation by plaintiffs who allege
          that they have suffered personal injury as a result of exposure to
          asbestos-containing products.  As of November 1, 1995, the
          Corporation is defending lawsuits and claims of approximately 38,000
          such plaintiffs and anticipates that additional suits or claims will
          be filed against it over the next several years.  These suits allege
          a variety of lung and other diseases based on alleged exposure to
          products previously manufactured by the Corporation.  In many cases
          the plaintiffs are unable to demonstrate that they have suffered any
          compensable loss as a result of such exposure.

          The Corporation generally resolves asbestos cases by voluntary
          dismissal or settlement for amounts it considers reasonable given
          the facts and circumstances of each case.  The amounts it has paid
          in settlement have been substantially covered by product liability
          insurance, and the Corporation believes that it has insurance
          available in amounts adequate to cover substantially all of the
          reasonably foreseeable damages and settlement amounts arising out of
          claims and suits currently pending.  The Corporation also
          anticipates that equivalent amounts of insurance will be available
          with respect to the disposition of suits and claims that may be
          filed against the Corporation in the future, but there can be no
          assurance in this regard.  The Corporation has established reserves
          for liabilities and legal defense costs for these suits and claims
          in amounts it believes are probable and reasonably estimable.  It
          also has recorded a receivable for expected insurance recoveries
          with respect to pending suits and claims.

          On October 2, 1995, the Corporation was sued in an action in state
          court in Mobile, Alabama, (Bettner, et al. v. Georgia-Pacific
          Corporation) that seeks to certify a class of all persons currently
          owning structures in the United States on which hardboard siding
          manufactured by the Corporation after January 1, 1980 has been
          installed.  The plaintiffs allege that the hardboard siding
          manufactured and distributed by Georgia-Pacific was inadequately
          designed and manufactured and as a consequence prematurely discolors
          and deteriorates when exposed to moisture and other climatic
          conditions.  The plaintiffs also dispute the validity and
          availability of the warranty issued with the product.  Plaintiffs
          seek unspecified compensatory and punitive damages, declaratory
          relief regarding the availability of warranties, restitution and
          injunctive relief.  Although there can be no assurances as to the
          ultimate outcome of this litigation, the Corporation believes that 


<PAGE>   9

          it has meritorious defenses to the claims of plaintiffs, and
          that it has accepted and paid all valid warranty claims of its
          customers.

          Although the ultimate outcome of these environmental matters and
          legal proceedings cannot be determined with certainty, based on
          presently available information management believes that adequate
          reserves have been established for probable losses with respect
          thereto and that such ultimate outcome, after taking such reserves
          into account, will not have a material adverse effect on the
          consolidated financial position of the Corporation.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

THREE MONTHS ENDED SEPTEMBER 30, 1995 COMPARED WITH 1994

The Corporation reported consolidated net sales of $3.7 billion for the three
months ended September 30, 1995, compared with $3.3 billion for the same 1994
period, an increase of 13.4 percent.  The Corporation also reported an increase
in net income for the three months ended September 30, 1995 ($324 million or
$3.57 per share), compared with net income for the 1994 third quarter ($87
million or 98 cents per share).

The remaining discussion refers to the "Sales and Operating Profits by Industry
Segment" table and Statements of Income (included in Part I - Item 1. hereto).

The Corporation's building products segment reported net sales of $1.9 billion
and operating profits of $221 million for the three months ended September 30,
1995.  For the same 1994 period, reported net sales were $1.9 billion and
operating profits were $262 million.  Accordingly, return on sales decreased to
11.6 percent from 13.5 percent a year ago.  The decrease in operating profits is
primarily the result of a decrease in third quarter average prices of
approximately 12 percent for the Corporation's softwood lumber business compared
with a year ago.  Operating profits for this business were also impacted
by higher wood costs compared with year ago levels and, in part, by an increase
in the availability of Canadian lumber.  Although average plywood prices for the
third quarter were approximately 4 percent higher than the 1994 third quarter,
operating profits, like the softwood lumber business, were adversely affected by
higher wood costs.  Finally, 1995 third quarter profits for the Corporation's
distribution business were lower than the same 1994 period primarily because of
increased costs ascribed to initiatives to change and improve certain
administrative processes of that business (discussed in the Corporation's
Quarterly Report on Form 10-Q for the quarter ended June 30, 1995).

The pulp and paper segment reported $1.8 billion in net sales in the 1995 third
quarter, up from $1.3 billion in the same 1994 period.  This segment also
reported operating profits of $478 million for this three month period compared
with operating profits of $83 million a year ago.  Return on sales increased
significantly in the 1995 third quarter compared with the 1994 third quarter
primarily as a result of higher prices for most of the Corporation's pulp and
paper products.  Third quarter average prices for market pulp increased more    
than 70 percent from 1994 third quarter average prices; average containerboard
prices increased more than 40 percent; communication paper prices increased more
than 60 percent; and corrugated packaging prices increased more than 30 percent
compared with third quarter 1994 levels.  However, during the 1995 third
quarter, the Corporation began to experience a slowing of demand for several of
its pulp and paper products.  As a result, operating profits for this business
in the fourth quarter are expected to decline from the third quarter.

General corporate expense decreased to $61 million for the three months ended
September 30, 1995 compared with $78 million in 1994.  The majority of the
decrease is attributable to compensation programs tied to the Corporation's
common stock price.

For the third quarter, the Corporation's interest expense and cost of accounts  
receivable sale program were a combined $102 million, a decrease of 14.3 
percent compared with $119 million a year ago.  Lower expense in 1995 was 
primarily the result of a lower level of debt and the expiration since 
September 30, 1994 of $500 million in interest rate exchange agreements which 
had effectively fixed the rates on a portion of the Corporation's variable rate 
debt.

The Corporation reported pretax income of $540 million and an income tax
provision of $216 million for the three months ended September 30, 1995.  The
Corporation reported pretax income of $151 million and an income tax provision
of $64 million for the three months ended September 30, 1994.  The actual
effective tax rate for both periods was different than the federal statutory 




<PAGE>   13


tax rate primarily because of nondeductible goodwill amortization expense.


NINE MONTHS ENDED SEPTEMBER 30, 1995 COMPARED WITH 1994

The Corporation reported consolidated net sales for the nine months ended
September 30, 1995 of $10.9 billion, compared with $9.4 billion in 1994.
Consolidated net income was $821 million ($9.12 per share), compared with $141
million ($1.59 per share) in the 1994 comparable period.  The 1994 results
include a net, after-tax gain of $34 million (38 cents per share) primarily
related to the sale of the Corporation's envelope and roofing manufacturing
businesses.  In addition, 1994 net income includes an $11 million (12 cents per
share) after-tax loss on the early retirement of debt and a $5 million (6 cents
per share) one-time after-tax charge for an accounting change.

The remaining discussion refers to the "Sales and Operating Profits by Industry
Segment" table and Statements of Income (included in Part I - Item 1. hereto).

The building products segment reported net sales of $5.6 billion for the nine
months ended September 30, 1995, a slight decrease from the first nine months
of 1994.  Operating profits also declined to $561 million for the nine-month
period ended September 30, 1995, compared with $727 million in 1994.  Return 
on sales decreased to 10.1 percent from 12.8 percent a year ago.  Rising wood 
costs in the Corporation's softwood lumber and plywood businesses, due in part 
to an increase in the supply of Canadian lumber compared with a year ago, have
continued to affect the building products segment results.  For example, year-
to-date average softwood lumber prices are 11 percent below average in 1994;
and although average plywood prices for the first nine months of 1995 are 8 
percent higher than average for the first nine months of 1994, profits were 
adversely affected by the rise in wood costs.

The Corporation's pulp and paper segment reported net sales of $5.3 billion and
operating profits of $1.3 billion for the nine-month period ended September 30,
1995.  For the same 1994 period, the segment reported net sales of $3.7 billion
and an operating loss of $10 million.  The improved results in 1995 are
primarily attributable to significantly higher average prices during the first
nine months of 1995 for most of the Corporation's pulp and paper products,
compared with the first nine months of 1994.  Average market pulp prices
increased by more than 80 percent, corrugated packaging average prices
increased by more than 30  percent, and average communication paper and 
containerboard prices increased by more than 50 percent.

General corporate expense of $178 million for the nine months ended September
30, 1995 increased 30.0 percent from the 1994 year-to-date expense of $137
million.  The increase is primarily attributable to the costs of initiatives to
change and improve certain administrative processes.

The Corporation reported a combined $330 million for interest expense and the
cost of the accounts receivable sale program for the first three quarters of
1995, a decrease of 10.1 percent from $367 million for the first three quarters
of 1994.  The decrease is primarily the result of the expiration since September
30, 1994 of $500 million in interest rate exchange agreements which had
effectively fixed the rates on a portion of the Corporation's variable rate
debt.

The Corporation reported pretax income of $1.4 billion and an income tax
provision of $548 million for the nine months ended September 30, 1995.
Excluding asset sales, the Corporation reported pretax income before
extraordinary item and accounting change of $225 million and an income tax
provision of $102 million for the nine months ended September 30, 1994.  


<PAGE>   14

The actual effective tax rate for both periods was different than the federal 
statutory tax rate primarily because of nondeductible goodwill amortization 
expense.

Selling, general and administrative expenses for the nine-month period ended
September 30, 1995 increased 18.3 percent to $1.1 billion from $906 million for
the same 1994 period, primarily due to labor, systems and other costs
associated with initiatives to change and improve certain operating and 
administrative processes.


Liquidity and Capital Resources
Operating Activities

The Corporation generated cash from operations of $1.1 billion for the nine
months ended September 30, 1995, compared with $389 million for the same 1994
period.  These results include a $200 million reduction in the accounts
receivable sale program in June 1995 and tax payments of $84 million paid to
the Internal Revenue Service in 1994.  The tax payments were to settle the 
1989 and 1990 tax years for the Corporation and to resolve substantially all 
pending income tax issues related to Great Northern Nekoosa Corporation for the 
years 1985 through March 1990.  Excluding these items, cash provided by 
operations in 1995 and 1994 was $1.3 billion and $473 million, respectively.  
The increase in cash from operations is primarily the result of higher prices 
in the Corporation's pulp and paper segment for the nine-month period ended 
September 30, 1995 compared with the first nine months of 1994.


Investing Activities

During the first nine months of 1995, the Corporation spent $887 million on
capital expenditures, including $415 million in the pulp and paper segment,
$366 million in the building products segment, $60 million for timber and
timberlands and $46 million in other expenditures.  The Corporation's total 
projected capital spending for 1995 is approximately $1.2 billion.

As previously disclosed in the Corporation's Annual Report on Form 10-K for the
year ended December 31, 1994, the sales of its roofing manufacturing and
envelope businesses were completed during the first quarter of 1994.  The
Corporation received after-tax cash proceeds of approximately $156 million from
these transactions.


Financing Activities

Total debt of the Corporation, including $500 million in the accounts
receivable sale program and excluding $366 million in marketable securities, 
was $5.4 billion as of September 30, 1995, a decrease of $307 million since 
December 31, 1994.  This includes a net increase in long-term debt of $340 
million and a net increase in bank overdrafts of $12 million, both of which 
were partially offset by a reduction in the accounts receivable sale program of
$200 million and a net decrease of $459 million in commercial paper and 
short-term notes.

On September 29, 1995, the Corporation sold certain of its assets for $354
million.  The Corporation has agreed to lease the assets back from the
purchaser over a period of 30 years.  Under the agreement with the purchaser, 
the Corporation will maintain a deposit (initially in the amount of $322 
million) which together with interest is expected to be sufficient to fund the
Corporation's obligations.  In accordance with generally accepted accounting
principles, the lease transaction is being accounted for as a financing
arrangement.  Accordingly, the Corporation has recorded on its balance sheet at
September 30, 1995 a long-term asset for the proceeds received from the sale
and a long-term liability for the lease obligation.

At September 30, 1995, the Corporation borrowed funds on a short-term basis to
establish the deposit account.  The proceeds from the asset sale were invested
in marketable securities until such securities matured on October 5, 1995, when

<PAGE>   15

they were used to reduce short-term borrowings. The Corporation treated these 
marketable securities as cash equivalents at September 30, 1995 because of 
their near-term maturities.

During the 1995 second quarter, the Corporation issued $250 million of  8-5/8%
Debentures Due April 30, 2025 and $250 million of 7.70% Debentures Due June 15,
2015.  In addition, the Corporation redeemed at par $200 million of its 10-1/8%
Debentures.  Effective June 29, 1995, the Corporation repurchased $200 million
of receivables, reducing the accounts receivable sale program from $700 million
to $500 million.

In the first quarter of 1994, the Corporation called for redemption
approximately $204 million in principal of its 10-1/4% Debentures Due September
15, 2018, which it redeemed in April 1994.  The Corporation reported an after-
tax extraordinary loss of $11 million (12 cents per share) in the first half of
1994 as a result of this early retirement.

The Corporation has a $1.5 billion unsecured revolving credit facility which is
used for direct borrowings and as support for commercial paper and other short-
term borrowings, including bid borrowings made under that agreement.  As of
September 30, 1995, $725 million of committed credit was available in excess of
all short-term borrowings outstanding under or supported by the facility.

The Corporation's weighted average interest rate on total debt as of September
30, 1995 and 1994 was 8.0%, including the accounts receivable sale program and
the outstanding interest rate exchange agreements.

At September 30, 1995, the Corporation had outstanding interest rate exchange
agreements which effectively converted $546 million of floating rate    
obligations with a weighted average interest rate of approximately 5.9% to fixed
rate obligations with an average effective interest rate of approximately 9.2%. 
On that date, the Corporation's total floating rate debt, including the accounts
receivable sale program, exceeded related interest rate exchange agreements by
approximately $1.4 billion.  Interest rate exchange agreements of $400 million
expired in 1995 and another $50 million of these agreements are due to expire in
November.

As previously reported in the Corporation's Quarterly Report on Form 10-Q for
the quarter ended June 30, 1995, the Corporation's Board of Directors   
authorized management to make purchases of the Corporation's common stock on the
open market or in private transactions.  Purchases will be made from time to
time using available cash provided that total debt, including the accounts
receivable sale program, is less than $5.5 billion after funding all other cash
requirements of the Corporation.  As of September 30, 1995, no purchases had
been made.

As of September 30, 1995, the Corporation had registered for sale up to $250
million of debt securities under a shelf registration statement filed with the
Securities and Exchange Commission.

In 1995, the Corporation expects its cash flow from operations, together with
proceeds from any asset sales and available financing sources, to be sufficient
to fund planned capital investments, pay dividends and make scheduled debt and
interest payments.

                               September 30, 1995


ITEM 1.   LEGAL PROCEEDINGS

The information contained in Note 10 "Commitments and Contingencies" of the
Notes to Financial Statements filed as part of this Quarterly Report on Form
10-Q is incorporated herein by reference.

As last reported in the Corporation's Quarterly Report on Form 10-Q for the
quarter ended March 31, 1995, the EPA filed a Complaint and Compliance Order
("Order") against the Corporation on September 30, 1994, for alleged
violations of the Resource Conservation and Recovery Act at its Brunswick,
Georgia, pulp and paper mill.  The Order alleged disposal of black liquor
without a permit, treatment of wastewater from accumulated lime mud without a
permit, and failure to respond to a spill of sulfuric acid in a manner adequate
to minimize the flow of hazardous waste.  This matter was settled by Consent
Agreement and Consent Order dated September 29, 1995, pursuant to which the
Corporation paid a penalty of $127,168.50 and is obligated to perform certain
cleanup tasks, for which the current cost estimate is not considered material
to the Corporation.

ITEM 5.   OTHER INFORMATION.

On November 9, 1995, the Corporation and Domtar Inc. announced that they had
executed agreements pursuant to which the Corporation will purchase Domtar's
gypsum wallboard business for $350 million in cash.  Domtar's gypsum business
includes nine U.S. and four Canadian wallboard manufacturing plants, and one
gypsum paperboard plant.  The acquisition is subject to compliance with U.S.
and Canadian antitrust laws and other regulatory approvals.  The Corporation
anticipates the transaction will be closed in the first quarter 1996.

                 Purchaser and the Purchaser shall purchase, assume and accept
                 from the Vendor, at the Closing but with effect as at the

<PAGE>   23

                                      -18-

                 assignment and transfer of the Accounts Receivable, in each
                 case, on the forms and within the delays prescribed for such
                 purposes, and shall also prepare and file all of their
                 respective tax returns in a manner consistent with the
                 election stipulated in this Section 2.5.

         2.6     GOODS AND SERVICES TAX ELECTION

                 The Parties shall jointly make and execute an election under
                 Section 167 of the Excise Tax Act (Canada) and Section 75 of
                 the Quebec Sales Tax Act on the forms prescribed for such
                 purposes along with any documentation necessary or desirable
                 in order to effect the transfer of the Business and Purchased
                 Assets by the Vendor without payment of any Goods and Services
                 Tax ("GST") or Quebec Sales Tax ("QST").  The Purchaser shall
                 file the election forms referred to in this Section 2.6,
                 together with any documentation necessary or desirable to give
                 effect to such election, with Revenue Canada and the Ministere
                 du Revenu du Quebec, respectively, together with the
                 Purchaser's GST and QST returns for the reporting period in
                 which the transactions provided for herein are consummated.
                 Notwithstanding such election, in the event that it is
                 determined by Revenue Canada or by the Ministere du Revenu du
                 Quebec that there is a GST or QST liability of the Purchaser
                 to pay GST or QST on all or part of the Business or Purchased
                 Assets, such GST or QST, as the case may be, shall, unless
                 already collected from the Purchaser and remitted by the
                 Vendor be forthwith remitted by the Purchaser to Revenue
                 Canada or the Ministere du Revenu du Quebec, as the case may
                 be.  Should the Vendor be assessed by Revenue Canada or the
                 Ministere du Revenu du Quebec for any such GST or QST
                 liability, the Purchaser shall indemnify and hold harmless the
                 Vendor for all taxes, interest and penalties which the Vendor
                 may be required to pay.

         2.7     Adjustment of Purchase Price

                 2.7.1    An adjustment, if any, based on U.S. GAAP, with
                          respect to the Purchase Price shall be made as of the
                          Adjustment Date as follows:

                          2.7.1.1     if the value of the Owner's Equity as
                                      determined by the Adjustment Balance
                                      Sheet exceeds the value of the Owner's
                                      Equity as determined by the Interim
                                      Balance Sheet, the Purchaser shall pay to
                                      the Vendor, as an adjustment to the
                                      Purchase Price, the amount of such
                                      excess; and

<PAGE>   24

                                      -19-

                          2.7.1.2     if the value of the Owner's Equity as
                                      determined by the Interim Balance Sheet
                                      exceeds the value of the Owner's Equity
                                      as determined by the Adjustment Balance
                                      Sheet, the Vendor shall pay to the
                                      Purchaser, as an adjustment to the
                                      Purchase Price, the amount of such
                                      excess.

                 2.7.2    The amount of any adjustment payable in accordance
                          with the provisions of this Section 2.7 shall bear
                          interest at the prime rate of Mellon Bank calculated
                          from the Adjustment Date until paid in full, and the
                          amount of any such adjustment and interest accrued
                          thereon shall be paid, subject to Section 2.7.4, on
                          the Adjustment Payment Date by wire transfer or
                          certified cheque payable to or as directed by the
                          Party entitled thereto pursuant to the provisions of
                          this Section 2.7.  If the Adjustment Payment Date is
                          the Closing Date, the adjustment may be added to or
                          netted against the Purchase Price, as the case may
                          be.

                 2.7.3    For the purposes hereof, the "prime rate of Mellon
                          Bank" means the prime rate of Mellon Bank announced
                          by said Bank from time to time in Pittsburgh,
                          Pennsylvania, as its reference rate of interest
                          (commonly known as its prime rate) for commercial
                          loans made by said Bank in the United States in
                          United States of America dollars.

                 2.7.4    Within sixty (60) days after the Adjustment Date, the
                          Vendor shall (i) prepare the Adjustment Balance
                          Sheet, a calculation of Owner's Equity pursuant
                          thereto, and a calculation, in accordance with this
                          Section 2.7, of the Purchase Price adjustment (if
                          any) and (ii) deliver to the Purchaser a copy of such
                          Adjustment Balance Sheet and calculations.  If the
                          Purchaser is satisfied that the Purchase Price
                          adjustment as calculated and submitted by the Vendor
                          has been properly calculated, the Purchaser shall so
                          notify the Vendor.  If the Purchaser disagrees with
                          such calculation of the Purchase Price adjustment
                          (whether such objection relates to the mathematical
                          calculation thereof or of Owner's Equity, to the
                          Adjustment Balance Sheet or its preparation, or any
                          combination thereof) calculated by the Vendor, then
                          the Purchaser shall deliver to the Vendor, within
                          thirty (30) days after delivery to the Purchaser of
                          the Vendor's calculation of the Purchase Price
                          adjustment (the "INITIAL 30-DAY PERIOD"), a written
                          description of any adjustment proposed by the
                          Purchaser to such calculation, and the Vendor and the
                          Purchaser shall negotiate in good faith to resolve

<PAGE>   25

                                      -20-

                          any disagreement with respect thereto.  If the
                          Purchaser fails to give the Vendor notification
                          within the Initial 30-Day Period of any objection to
                          such calculation of the Purchase Price adjustment (or
                          gives objections only to portions thereof), then such
                          calculation (or the part not objected to) shall be
                          binding upon the Parties.  Any undisputed amount
                          shall be paid promptly on or before the later of (i)
                          the Closing Date or (ii) the fifth (5th) Business Day
                          after the Initial 30-Day Period.  If the Vendor and
                          the Purchaser have not resolved any such disagreement
                          (or portion thereof) within fifty (50) days following
                          the date on which the Purchaser receives the Vendor's
                          proposed adjustment to the Purchase Price, then such
                          disagreement shall be submitted to the Adjustment
                          Arbitrator for a final and binding resolution of the
                          disagreement and calculation of the final Purchase
                          Price adjustment.  The costs and expenses for the
                          services of the Adjustment Arbitrator shall be borne
                          by the Party whose position in the dispute submitted
                          to the Adjustment Arbitrator has the greatest dollar
                          discrepancy from the calculation determined by the
                          Adjustment Arbitrator.

                          The Adjustment Arbitrator shall be chosen as follow:

                          (i)     if the amount of the dispute is less than or
                                  equal to $1,000,000, the Adjustment
                                  Arbitrator shall be KPMG-Peat Marwick in
                                  Chicago; or

                          (ii)    if the amount of the dispute is in excess of
                                  $1,000,000, then three arbitrators shall be
                                  chosen from a list of ten (10) disinterested
                                  accountants in Chicago or its vicinity
                                  compiled by the American Arbitration
                                  Association, with the Vendor and the
                                  Purchaser alternatively striking a name from
                                  such list until only three names remain.  The
                                  Vendor shall have the right to strike the
                                  first name, and such right shall be exercised
                                  within five (5) Business Days after the list
                                  is presented to both the Vendor and the
                                  Purchaser.  Thereafter in turn, the Purchaser
                                  and the Vendor shall have two (2) Business
                                  Days after notification to it of the last
                                  name stricken by the other Party, to strike a
                                  name from the list until only three (3) names
                                  are left.  The arbitrators shall be those
                                  three (3) Persons whose names remain after
                                  the above process.  If any such Person cannot
                                  or does not serve as an arbitrator, then such
                                  Person shall be replaced by the Person whose
                                  name was last stricken who is available.  If
                                  any Party fails to strike a name from the
                                  list within the allotted time, then the other

         3.1     TRANSFER AND DELIVERY

                 Subject to the provisions of Sections 3.2 and 3.3 hereof, at
                 the Closing, the Vendor shall execute and deliver to the

                 title as shall be necessary to transfer title to the Business

                 the Purchaser possession of the Business and Purchased Assets,
                 in each case, with effect as at the Effective Time.

         3.2     ASSIGNMENT

                 Nothing in this Agreement shall be construed as a sale,
                 assignment or transfer, or an attempted sale, assignment or
                 transfer, of any of the Contracts, Accounts Receivable,
                 Operating Permits, Environmental Permits or other Purchased
                 Assets (collectively, the "RIGHTS") if such Right can only be
                 obtained or exercised by the Purchaser if it is re-issued or
                 issued to the Purchaser by a Person (if such re-issuance or
                 issuance has not been obtained) or if such Right is not
                 saleable, assignable or transferable without the consent,
                 approval, registration, filing, application, notice, transfer,
                 order, qualification, waiver or other action of any kind of a
                 Person (a "CONSENT") (if such Consent has not been obtained)
                 and such sale, assignment or transfer or attempted sale,
                 assignment or transfer would constitute a breach of such Right
                 or of any agreement or instrument by which the Vendor is bound
                 with respect to such Right.  The Vendor hereby represents and

                 warrants that set forth on SCHEDULE 3.2 is a true, correct and
                 complete list of all Consents, the failure of which to obtain
                 prior to the Closing Date might reasonably be expected to have
                 a Material Adverse Effect.

         3.3     CONSENTS TO ASSIGNMENTS

                 The Vendor shall exercise its best efforts to obtain, and
                 cooperate with the Purchaser for the purpose of obtaining, all

                 transfer by the Vendor to the Purchaser of the Rights
                 (including, without limitation, the re-issuance or issuance in

                 Operating Permits or Environmental Permits which are
                 non-saleable, non-assignable or non-transferable).  If any
                 Person whose Consent is required does not consent to the sale,
                 assignment or transfer of any of the Rights from the Vendor to
                 the Purchaser, the Vendor shall, at the request of the
                 Purchaser and to the extent permitted by the Laws and
                 Environmental Laws, enforce, use, carry-out and comply with
                 such Right against such Person as mandatary and agent, and for
                 the exclusive benefit of, the Purchaser, provided that the
                 Vendor shall not be liable for any loss (including, without
                 limitation, loss of profits or economic loss) or damages
                 (including, without limitation, indirect, consequential or
                 incidental damages) suffered or incurred by the Purchaser as a
                 result of the failure to obtain any Consent to the sale,
                 assignment or transfer of the Rights (including, without
                 limitation, the re-issuance or issuance in the name and for
                 the benefit of the Purchaser of the Operating Permits and
                 Environmental Permits or of permits, licenses, certificates
                 and authorizations to replace those of the Operating Permits
                 or Environmental Permits which are non-saleable,
                 non-assignable or non-transferable) or arising from any such
                 attempted sale, assignment or transfer.

         3.4     ASSUMPTION OF ASSUMED LIABILITIES

                 The Purchaser shall assume and become liable for, and shall
                 pay, perform, discharge, satisfy and fulfil, in a timely
                 manner and strictly in accordance with their terms, the
                 Assumed Liabilities as at and with effect from the Effective

                                           or the lapse of time, or both,

                                           defaults, or terminations which are
                                           not likely to have a Material
                                           Adverse Effect; or

                              4.3.1.3      result in the creation or imposition
                                           of any Lien upon the Purchased

                              Vendor which, if adversely determined, may
                              interfere with the sale, assignment, transfer or
                              delivery of the Business and Purchased Assets or
                              the consummation of any of the transactions

         4.4     NO OPTION

                 No Person has any agreement, option or right capable of
                 becoming an agreement or option to acquire the Business or any
                 of the Purchased Assets, or that would restrict the ability of
                 the Vendor to transfer the Purchased Assets to the Purchaser
                 hereunder, other than pursuant to purchase orders for
                 Inventory accepted by the Vendor in the ordinary course of the
                 Business.

                 the Business in compliance with all Laws of each jurisdiction
                 in which it presently conducts the Business and is duly
                 qualified, licensed or registered in each jurisdiction in
                 which the nature of the Business or the Purchased Assets makes
                 such qualification, licensing or registration necessary,
                 except where the failure to so comply or to be so qualified,
                 registered or licensed is not likely to have a Material
                 Adverse Effect.

         4.6     FINANCIAL STATEMENTS

                 4.6.1        The Financial Statements present fairly, in all
                              material respects, the results of operations and

                              calculated, in accordance with U.S. GAAP applied
                              on a consistent basis throughout the periods

                              manner as such Business has been conducted by the
                              Vendor since December 31, 1994, without any need
                              for replacement, refurbishment or repair

                              does not exist (i) any encroachment by any 
                              building or structure not owned by the Vendor on 
                              the Real Properties nor any encroachment by any

                              Vendor exists in respect of the Material

                              licenses, certificates and authorizations of, and

                 4.15.2       There is no claim, suit, action or other
                              proceeding, including appeals and applications
                              for review, outstanding or pending or, to the
                              best of the Vendor's knowledge, threatened
                              against the Vendor in respect of the Business or
                              Purchased Assets pursuant to any of the

                              knowledge, no facts or circumstances exist which

                              claim, suit, action or other proceeding which
                              would have a Material Adverse Effect.

                              Hazardous Substances on or from the Locations,
                              except in such a manner or quantity as would not
                              constitute a violation of any of the
                              Environmental Laws or Environmental Permits or
                              would not reasonably be expected to result in a

                 4.15.4       The Vendor has maintained in respect of the
                              Business and Purchased Assets records
                              substantially in the manner and for the time
                              periods required by the Environmental Laws and

                 4.15.5       The Vendor has no knowledge of any fact or
                              circumstance that is likely to prohibit or
                              prevent the issuance to the Purchaser of any of
                              the permits, licenses, certificates and
                              authorizations of, and registrations with, any of
                              the Environmental Authorities pursuant to any of
                              the Environmental Laws, which are necessary for

                              and, to the best of the Vendor's knowledge, there
                              are no facts or circumstances that would result
                              in the issuance of an Environmental Notice (i)
                              which would require that capital expenditures in
                              excess of $1,000,000 in the aggregate be made in
                              respect of the Business or Purchased Assets as a
                              condition of compliance with all of the
                              Environmental Laws or Environmental Permits, or
                              (ii) to the effect that any of the Environmental
                              Permits is about to be made subject to
                              limitations or conditions or revoked.

                              written consent of the Purchaser, any
                              modification to the Vendor's Pension Plans
                              between the Effective Time and the date of the
                              actual transfer of the Amounts (the "TRANSITIONAL
                              PERIOD"), if such modifications would affect the
                              Amounts, the benefits accrued to the Unionized
                              Non-Leave Employees, Transferring Employees and
                              Retired Employees up to the Effective Time or the
                              contributions with respect to such benefits.
                              Notwithstanding anything in this Section 6.3.6 to
                              the contrary, if a change proposed by the Vendor
                              is mandated by the Law, the Vendor need not
                              obtain the Purchaser's prior approval (but prior
                              notice is still required) unless the latest
                              effective date of the change permitted by Law (as
                              applied to the Vendor Pension Plan in question)
                              falls more than sixty (60) days after the date on
                              which the requirement of the Law was first
                              published or the requirement of the Law may be
                              satisfied in more than one way.

                 6.3.7        For the purposes of Section 6.3.2 hereof, the
                              Amounts shall equal the projected benefit
                              obligation under the Vendor's Pension Plans in
                              respect of the Unionized Non-Leave Employees,
                              Tranferring Employees and Retired Employees.  The
                              Amounts shall be determined as at the Effective
                              Time using the same funding actuarial methods and
                              assumptions as those used in the actuarial
                              valuations of the Vendor's Pension Plans as at

                              du Quebec as set out in SCHEDULE 6.3.7.

                              For the purposes of this Section 6.3.7, the
                              projected benefit obligation will be calculated
                              on the basis that the temporary formulas set out
                              in the actuarial valuations referred to in the
                              preceding paragraph of this Section 6.3.7 are
                              permanent and that salary projections will be
                              extended without limit in accordance with normal
                              actuarial practice.  In case of any ambiguity,
                              this paragraph of Section 6.3.7 shall prevail
                              over SCHEDULE 6.3.7.  The Vendor undertakes to
                              amend the Vendor's Pension Plans prior to the
                              Closing Date so as to give effect to the
                              provisions contained in the preceding sentence.

                 6.3.8        The Vendor shall be responsible for the division
                              of the Vendor's Pension Plans in accordance with
                              the Laws, including the preparation of the
                              relevant actuarial reports.  These reports shall
                              be completed within a period of five (5) months
                              from and after the Effective Time and a copy of
                              these reports shall be delivered to the Purchaser
                              prior to their filing with the relevant
                              regulatory authorities.

                 6.3.9        The Purchaser's actuary shall have sixty (60)
                              Business Days from receipt of such actuarial
                              reports to complete its review pursuant to the
                              standards set forth in Section 6.3.10 and to
                              report its findings to the Purchaser and the
                              Vendor.  No filings with any regulatory body of
                              any kind (including for greater certainty, but
                              without limitation, actuarial reports) regarding
                              the division of the Vendor Pension Plans may be
                              made without prior review and approval of the
                              entire filing by the Purchaser.  If the
                              Purchaser's actuary contests the Vendor's
                              actuary's calculations, a final determination
                              shall be made by an independent third party
                              actuary acceptable to the Parties, and each Party
                              shall be responsible for one half of the cost of
                              such final determination by such independent
                              third party actuary.

                 6.3.10       During the Transitional Period, the Amounts and
                              all adjustments thereof shall be credited with
                              interest at the following rates:

                          (i)       for the period ending on the date of
                                    determination of the last known rate of
                                    return of the pension fund of the relevant
                                    Vendor's Pension Plan (the "INITIAL
                                    PERIOD"), the rates of return of the

                                    pension fund of said relevant Vendor's 
                                    Pension Plan; and

                          (ii)      from the end of the Initial Period to the
                                    date of the actual transfer of the Amounts,
                                    investment return rate assumed under the
                                    actuarial assumptions set out in SCHEDULE
                                    6.3.7.

                              The transfer of the Amounts and the adjustments
                              shall be made as set out in SCHEDULE 6.3.10.

                 6.3.11       The Vendor shall indemnify and hold the Purchaser
                              and the Purchaser's Employee Plans harmless
                              against any claims, liabilities and expenses
                              (including, for greater certainty and without
                              limitation, attorney's fees) arising from the
                              failure of the Vendor's Pension Plans to be in
                              compliance with applicable Laws (including,
                              without limitation, those pertaining to
                              registration standards and favourable tax
                              treatment of registered plans) at the time of the
                              asset transfers.

         6.4     CANADA AND QUEBEC SAVINGS BONDS

                 Canada and Quebec savings bonds purchase programs (the
                 "SAVINGS BONDS PROGRAMS") have been instituted by the Vendor
                 for the benefit of its Employees.  The Unionized Non-Leave
                 Employees and Transferring Employees listed in SCHEDULE 6.4
                 participate in the Savings Bonds Programs and their
                 contributions for the purchase of such bonds are deducted from
                 their salaries.  The Vendor shall continue to administer the
                 Savings Bond Programs following the Effective Time, but shall
                 assign to the Purchaser, at the Closing but with effect as at
                 the Effective Time, the right to collect the payments due from
                 the said participating Employees with respect to the Savings
                 Bonds Programs.  The Purchaser shall assume responsibility for
                 collecting the payments due from the said participating
                 Employees with respect to the Savings Bonds Programs and shall
                 remit to the Vendor such collected funds within thirty (30)
                 Business Days following the end of the calendar month in which
                 they are collected.  The Purchaser's obligation in this regard
                 shall continue until the said participating Employees are no
                 longer employed by the Purchaser or, if earlier, have paid in
                 full the amounts remaining to be paid, under the Savings Bonds
                 Programs in effect as of the Effective Time.

                 The Vendor, immediately upon its receipt of the bonds, shall
                 distribute them to the said participating Employees.  The
                 Purchaser will cooperate with the Vendor by providing to the
                 Vendor any changes of address with respect to the said 

<PAGE>   51

                                      -46-

                 participating Employees and by notifying the Vendor of
                 the termination of the employment of any of the said
                 participating Employee.  Upon the receipt by the Vendor of
                 such contributions withheld by the Purchaser from the pay of
                 the said participating Employees, the Vendor shall forever
                 release the Purchaser from any liability pertaining thereto.

         6.5     EMPLOYEE SHARE PURCHASE AND EXECUTIVE STOCK OPTION AND 
                 PURCHASE PLANS

                 The Vendor shall terminate, as at the Effective Time, its
                 Employee Share Purchase Plans and Executive Stock Option and
                 Purchase Plans set out in SCHEDULE 4.16.3 insofar as the
                 Employees and Retired Employees are concerned and shall be
                 responsible for all benefits accrued as at the Effective Time
                 by the Employees and Retired Employees entitled to such
                 benefits under such plans.

         6.6     SUBSIDIZED MORTGAGE PLANS

                 The Purchaser shall assume the Vendor's obligations as at the
                 Effective Time under the Subsidized Mortgage Plans set out in
                 SCHEDULE 6.6 (the "SUBSIDIZED MORTGAGE PLANS") with respect to
                 affected Transferring Employees listed in such Schedule.  The
                 Purchaser shall also maintain for such Transferring Employees
                 the life insurance covering them in connection with their
                 mortgage subsidy in the event equal to the outstanding
                 principal amount as at the Effective Time for a period which
                 shall continue so long as such affected Transferring Employees
                 remain eligible for a mortgage subsidy under the Subsidized
                 Mortgage Plans.

         6.7     COOPERATION WITH RESPECT TO EMPLOYEE NOTICES

                 The Parties acknowledge that between the time of execution of
                 this Agreement and the Effective Time, it may be necessary
                 from time to time for the Purchaser to give written notices
                 for various purposes to the Employees regarding their future
                 employment with the Purchaser.  The Purchaser agrees not to
                 disseminate any such notices without having first consulted
                 with and obtained the consent of the Vendor, which consent
                 shall not be unreasonably withheld, and the Vendor agrees to
                 cooperate fully in the timely dissemination of such notices
                 upon request by the Purchaser.

ARTICLE 7.       REAL PROPERTIES

         The Vendor shall cause to be conducted, at its cost, title searches
         and the Vendor shall deliver to the Purchaser, on or prior to the
         Closing Date, title opinions with respect to the Real Properties,
         dated the Closing Date in form and substance satisfactory to the
         Purchaser's Counsel.

ARTICLE 8.       NON-COMPETITION

         8.1     NON-COMPETITION

                 From and after the Closing Date, the Vendor shall not, for a
                 period of five (5) years, on its own behalf or on behalf of
                 any other Person, directly or indirectly, in any capacity
                 whatsoever including, without limitation, as employer,
                 principal, mandator, agent, mandatary, joint venturer,
                 partner, shareholder or other equity holder, independent
                 contractor, manufacturer, seller, licensor, licensee,
                 franchisor, franchisee, distributor, consultant, supplier or
                 trustee or by or through any Person, conduct or be engaged in
                 or have financial interests in any gypsum wallboard business
                 in the United States of America or in Canada.

         8.2     PERMITTED ACTIVITIES

                 Notwithstanding the provisions of Section 8.1 hereof, the
                 Vendor shall not be prohibited from owning an interest, as
                 passive investor, in any gypsum wallboard business provided
                 that the interest owned, whether directly or indirectly, by
                 the Vendor in such business, if any, shall not exceed 10% of
                 all the outstanding equity securities of any Person whose
                 equity securities are listed on a recognized securities
                 exchange and with whom the Vendor does not have any connection
                 whatsoever except for such ownership interest.

         8.3     LIMITED EXCEPTION FOR INCIDENTAL ACQUISITIONS

                 Notwithstanding the provisions of Section 8.1 hereof, the
                 Vendor shall not be prohibited from acquiring assets (or a
                 controlling stock interest) of a Person where the assets of
                 such Person include gypsum wallboard assets (the "ACQUIRED
                 GYPSUM ASSETS"), provided that if the gross revenues generated
                 by the Acquired Gypsum Assets during the last full fiscal year
                 period (the "GROSS REVENUES") exceed $35,000,000, the Vendor
                 shall offer to sell the Acquired Gypsum Assets to the
                 Purchaser.  Such offer to the Purchaser shall be made by the
                 Vendor promptly upon the execution by the Vendor of a binding
                 agreement to purchase such assets (but in no event less than
                 thirty (30) days prior to closing the acquisition contemplated 

<PAGE>   53

                                      -48-

                 by such agreement). If the Purchaser elects to purchase
                 the Acquired Gypsum Assets, the Vendor and Purchaser shall
                 negotiate in good faith the price to be paid by the Purchaser
                 to the Vendor for the Acquired Gypsum Assets.  If the Vendor
                 and the Purchaser cannot agree upon the terms and conditions
                 of such sale, then the Vendor shall use its commercially
                 reasonable efforts to sell the Acquired Gypsum Assets to a
                 third party within two (2) years after negotiations with the
                 Purchaser cease, but no such sale shall be on terms and
                 conditions in the aggregate more favourable to the third party
                 than those offered to the Purchaser.  If the Gross Revenues
                 are less than or equal to $35,000,000, then the Vendor need
                 not offer the Acquired Gypsum Assets to the Purchaser, but if
                 the Vendor determines to sell the Acquired Gypsum Assets prior
                 to the fifth (5th) anniversary of the Closing, the Vendor
                 shall first offer the Acquired Gypsum Assets to the Purchaser
                 following the procedures set out in the preceding sentences of
                 this Section 8.3.

ARTICLE 9.       COVENANTS OF THE VENDOR

         The Vendor covenants and agrees with the Purchaser as follows:

         9.1     MAINTENANCE AND PRESERVATION OF BUSINESS

                 From and after the date hereof to the Closing Date or the date
                 of termination of the Parties' obligation to close under this
                 Agreement, the Vendor covenants to the Purchaser that, except
                 as may be specifically approved in writing by the Purchaser,
                 the Business will be conducted only in the ordinary course and

                          by the Vendor; however, the Vendor will notify the

                          compromise rights and claims in good faith which may

                 to operate the Business or to comply with its obligations

         12.5    INDEMNIFICATION AGAINST THIRD PARTY CLAIMS

                 12.5.1       Promptly upon receipt by either Party (the
                              "INDEMNITEE") of a notice of any Third Party
                              Claim in respect of which the Indemnitee proposes
                              to demand indemnification from the other Party
                              (the "INDEMNITOR"), the Indemnitee shall give
                              notice to that effect to the Indemnitor with
                              reasonable promptness.

                 12.5.2       Without prejudice to the Indemnitee's right to
                              participate in the defence, compromise or
                              settlement of the Third Party Claim, the
                              Indemnitor shall have the right by notice to the
                              Indemnitee not later than ten (10) days after
                              receipt of the notice described in Section 12.5.1
                              hereof to assume (and in the case of asbestos
                              claims, shall assume) the control of the defence,
                              compromise or settlement of the Third Party
                              Claim, provided that such assumption shall, by
                              its terms, be without cost or liability to the
                              Indemnitee and provided that the Indemnitor shall
                              have first delivered to Indemnitee a written
                              acknowledgement by the Indemnitor that the
                              relevant Claim is an Indemnified Claim and that
                              the Indemnitor, in its good faith judgment, will
                              be able to pay any award of money damages against
                              the Indemnitee in connection with such action.
                              If the Indemnitor assumes the defence of an
                              action, (i) the Indemnitee shall be entitled to
                              meaningfully participate therein; (ii) no
                              settlement or compromise thereof may be effected
                              (x) by the Indemnitor without the consent of the
                              Indemnitee (which consent shall not be
                              unreasonably withheld or delayed) unless (A)
                              there is no finding or admission of any violation
                              of law or any violation of the rights of any
                              person by the Indemnitee and no adverse effect on
                              any other claims that may be made against any
                              Indemnitee and (B) all relief provided is paid or
                              satisfied in full by the Indemnitor or (y) by the
                              Indemnitee without the consent of the Indemnitor;
                              and (iii) the Indemnitee may subsequently assume
                              the defence of such action if a court of
                              competent jurisdiction determines the Indemnitor
                              is not vigorously defending such action.

                 12.5.3       Upon the assumption of control by the Indemnitor
                              pursuant to the provisions of Section 12.5.2
                              hereof, the Indemnitor shall, at its expense,
                              diligently proceed with the defence, compromise
                              or settlement of the Third Party Claim at
                              Indemnitor's sole expense, including employment
                              of counsel reasonably satisfactory to the
                              Indemnitee and, in connection therewith, the
                              Indemnitee shall cooperate fully, but at the
                              expense of the Indemnitor, to make available to
                              the Indemnitor all pertinent information and
                              witnesses under the Indemnitee's control, make
                              such assignments and take such other steps as in
                              the opinion of counsel for the Indemnitor are
                              necessary to enable the Indemnitor to conduct
                              such defence.

                 12.5.4       The final determination of any such Third Party
                              Claim, including all related costs and expenses,
                              shall be binding and conclusive upon the Parties
                              as to the validity or invalidity, as the case may
                              be, of such Third Party Claim against the
                              Indemnitor.

                 12.5.5       Should the Indemnitor fail to defend the
                              Indemnitee as provided in Section 12.5.2 hereof,
                              the Indemnitee shall be entitled to make such
                              settlement of the Third Party Claim as in its
                              sole discretion may appear advisable, and such
                              settlement or any other final determination of
                              the Third Party Claim shall be binding upon the
                              Indemnitor.

                              Claims which either the Purchaser Protected
                              Persons or the Vendor Protected Persons shall be
                              entitled to receive pursuant to this Article 12

                              and all insurance proceeds received by the
                              Indemnitee from its insurers and any and all
                              recoveries from any other Persons against which
                              there may be indemnity rights pursuant to the
                              Contracts.  The Indemnitee shall use all
                              reasonable efforts to collect such insurance
                              proceeds or, if the Indemnitee is the Purchaser,

                              against any other Persons under any of the
                              Contracts; provided that nothing in this Section
                              12.6 shall require any Indemnitee to make or
                              prosecute a claim for insurance proceeds if such

                              a claim would adversely affect the Indemnitee 
                              with respect to matters other than the Claim.

                 12.6.2       COOPERATION

                              If an Indemnitee seeks indemnity from an

                              to environmental or asbestos related matters, the
                              Indemnitee shall cooperate with the Indemnitor,
                              at the Indemnitor's expense, in assisting the

                              any insurance policies maintained by the
                              Indemnitor covering the claims in question.

         12.7    VENDOR'S MAXIMUM LIABILITY

                 12.7.1       The obligation of the Vendor to indemnify the
                              Purchaser Protected Persons pursuant to this
                              Article 12, excluding the obligation to indemnify

                              exercise its right of indemnification in relation
                              thereto pursuant to this Article 12 unless and
                              until the aggregate amount of the Claims and

                              Purchase Price, and the amount then claimable
                              shall be only the amount of such Claims which
                              exceeds 1% of the Purchase Price;

                 12.7.2       Subject to the provisions of Sections 12.3.2,

                              sum obtained by adding to 15% of the Purchase
                              Price an amount equal to the difference between
                              10% of the Purchase Price and the aggregate of
                              the Claims indemnified against or outstanding,

                              amount of such Environmental Claims which exceeds
                              1% of the Purchase Price; and provided further
                              that the combined amount recoverable under

                 the Claim coming to the attention of the Indemnitee hereunder;
                 provided that failure to so notify the Indemnitor shall not
                 relieve the Indemnitor from any liabilities which it may have
                 to the Indemnitee (i) hereunder, except to the extent that is
                 actually prejudiced thereby, or (ii) otherwise than under this

ARTICLE 14.      TERMINATION

         14.1    ELECTION

                 The Parties shall exercise all reasonable efforts and
                 cooperate, with reasonable diligence, in order for the
                 consummation of the transactions contemplated hereunder to
                 take place at the earliest possible date.  Subject to the
                 provisions of Section 11.1.10 or 11.2.8 hereof, as the case
                 may be, in the event that the sale and purchase of the
                 Business and Purchased Assets herein provided for is not
                 consummated within five (5) months from the date of this
                 Agreement (the "FIVE-MONTH ANNIVERSARY") as a result of the
                 failure of either Party to fulfil any of the conditions
                 provided for in Section 11.1 or 11.2, as the case may be, for
                 the benefit of the other Party on or before the Five-Month
                 Anniversary and the Party who has the benefit of such
                 condition (the "ELECTING PARTY") refuses to waive it, the
                 Electing Party shall have the right, exercisable at any time
                 after the Five-Month Anniversary, to terminate this Agreement
                 by giving at least forty-five (45) days written notice to the
                 other Party (the "NON-ELECTING PARTY").  If the Non-Electing
                 Party does not cure its failure to fulfil the conditions of
                 Section 11.1 or 11.2, as the case may be, by the date for
                 termination (the "TERMINATION DATE") specified in the
                 termination notice given by the Electing Party, then this
                 Agreement shall terminate on the Termination Date, and, except
                 as set forth in Section 14.2 hereof, each Party shall be
                 released from

                 14.1.1       all obligations whatsoever to whomsoever
                              including, without limitation, all obligations to

                              pursuant hereto; and

                 14.1.2       all Claims arising out of, directly or
                              indirectly, the failure to consummate the sale
                              and purchase of the Business and Purchased Assets
                              as herein provided for.

         14.2    CONTINUING LIABILITY

                 If this Agreement is terminated concurrently with the
                 termination of the Share Purchase Agreement pursuant to
                 Section 13.1 thereof, effective as of a date after the Second
                 Fixture Date, because of the breach by the Purchaser under the
                 Share Purchase Agreement of its obligations under Article 9
                 (Antitrust and Competition Regulatory Approvals) under the
                 Share Purchase Agreement, then the Purchaser under this
                 Agreement shall remain liable to the Vendor for the failure to
                 consummate the sale and purchase of the Business and Purchased
                 Assets as herein provided.

                 The price payable by the Purchaser to the Vendor for the

                 the Closing Place by wire transfer or certified cheque payable
                 to the Vendor or as directed by the Vendor.

         3.2     ADJUSTMENT OF PURCHASE PRICE

                 3.2.1    An adjustment, if any, based on U.S. GAAP with
                          respect to the Purchase Price shall be made as of the
                          Adjustment Date as follows:

                          3.2.1.1     if the value of the Owner's Equity as
                                      determined by the Adjustment Balance
                                      Sheet exceeds the value of the Owner's

                                      Balance Sheet, the Purchaser shall pay to
                                      the Vendor, as an adjustment to the
                                      Purchase Price, the amount of such
                                      excess; and
<PAGE>   23

                                      -18-

                          3.2.1.2     if the value of the Owner's Equity as
                                      determined by the Interim Balance Sheet
                                      exceeds the value of the Owner's Equity
                                      as determined by the Adjustment Balance
                                      Sheet, the Vendor shall pay to the
                                      Purchaser, as an adjustment to the
                                      Purchase Price, the amount of such
                                      excess.

                 3.2.2    The amount of any adjustment payable in accordance
                          with the provisions of this Section 3.2 shall bear

                          from the Adjustment Date until paid in full, and the
                          amount of any such adjustment and interest accrued
                          thereon shall be paid, subject to Section 3.2.4, on
                          the Adjustment Payment Date by wire transfer or
                          certified cheque payable to or as directed by the
                          Party entitled thereto pursuant to the provisions of
                          this Section 3.2.  If the Adjustment Payment Date is
                          the Closing Date, the adjustment may be added to or
                          netted against the Purchase Price , as the case may
                          be.

                 3.2.3    For the purposes hereof, the "prime rate of Mellon
                          Bank" means the prime rate of Mellon Bank announced
                          by said Bank from time to time in Pittsburgh,
                          Pennsylvania, as its reference rate of interest
                          (commonly known as its prime rate) for commercial
                          loans made by said Bank in United States of America
                          in United States of America dollars.

                 3.2.4    Within sixty (60) days after the Adjustment Date, the
                          Vendor shall (i) prepare the Adjustment Balance
                          Sheet, a calculation of Owner's Equity pursuant
                          thereto, and a calculation, in accordance with this
                          Section 3.2, of the Purchase Price adjustment (if
                          any) and (ii) deliver to the Purchaser a copy of such
                          Adjustment Balance Sheet and calculations.  If the
                          Purchaser is satisfied that the Purchase Price
                          adjustment as calculated and submitted by the Vendor
                          has been properly calculated, the Purchaser shall so
                          notify the Vendor.  If the Purchaser disagrees with
                          such calculation of the Purchase Price adjustment
                          (whether such objection relates to the mathematical
                          calculation thereof or of Owner's Equity, to the
                          Adjustment Balance Sheet or its preparation, or any
                          combination thereof) calculated by the Vendor, then
                          the Purchaser shall deliver to the Vendor, within
                          thirty (30) days after delivery to the Purchaser of
                          the Vendor's calculation of the Purchase Price
                          adjustment (the "INITIAL 30-DAY PERIOD"), a written
                          description of any adjustment proposed by the
                          Purchaser to such calculation, and the Vendor and the
                          Purchaser shall negotiate in good faith to

                          resolve any disagreement with respect thereto.  If
                          the Purchaser fails to give the Vendor notification
                          within the Initial 30-Day Period of any objection to
                          such calculation of the Purchase Price adjustment (or
                          gives objections only to portions thereof), then such
                          calculation (or the part not objected to) shall be
                          binding upon the Parties.  Any undisputed amount
                          shall be paid promptly on or before the later of (i)
                          the Closing Date or (ii) the fifth (5th) Business Day
                          after the Initial 30-Day Period.  If the Vendor and
                          the Purchaser have not resolved any such disagreement
                          (or portion thereof) within fifty (50) days following
                          the date on which the Purchaser receives the Vendor's
                          proposed adjustment to the Purchase Price, then such
                          disagreement shall be submitted to the Adjustment
                          Arbitrator for a final and binding resolution of the
                          disagreement and calculation of the final Purchase
                          Price adjustment.  The costs and expenses for the
                          services of the Adjustment Arbitrator shall be borne
                          by the Party whose position in the dispute submitted
                          to the Adjustment Arbitrator has the greatest dollar
                          discrepancy from the calculation determined by the
                          Adjustment Arbitrator.

                          The Adjustment Arbitrator shall be chosen as follow:

                          (i)     if the amount of the dispute is less than or
                                  equal to $1,000,000, the Adjustment
                                  Arbitrator shall be the Chicago office of
                                  KPMG Peat Marwick; or

                          (ii)    if the amount of the dispute is in excess of
                                  $1,000,000, then three arbitrators shall be
                                  chosen from a list of 10 disinterested
                                  accountants in Chicago or its vicinity
                                  compiled by the American Arbitration
                                  Association, with the Vendor and the
                                  Purchaser alternatively striking a name from
                                  such list until only three names remain.  The
                                  Vendor shall have the right to strike the
                                  first name, and such right shall be exercised
                                  within five (5) Business Days after the list
                                  is presented to both the Vendor and the
                                  Purchaser.  Thereafter in turn, the Purchaser
                                  and the Vendor shall have two (2) Business
                                  Days after notification to it of the last
                                  name stricken by the other Party, to strike a
                                  name from the list until only three names are
                                  left.  The arbitrators shall be those three
                                  Persons whose names remain after the above
                                  process.  If any such Person cannot or does
                                  not serve as an arbitrator, then such Person
                                  shall be replaced by the Person whose name
                                  was last stricken who is available.  If any
                                  Party fails to strike a name from the list

                              customary for reasonably prudent Persons
                              operating like businesses and owning like
                              properties, all as provided for in and by the

                              of rights or have denied liability, and there
                              exists no claim under such insurance that has not
                              been properly filed with such insurers by the
                              Corporation or, where necessary, the Vendor or

                              necessary to conduct the Business substantially
                              as presently conducted.  The Environmental
                              Permits are in full force and effect and the
                              Corporation is in substantial compliance in all
                              respects thereunder.  The Corporation is in

                              to the conduct of the Business, except to the
                              extent such noncompliance would not constitute a
                              Material Adverse Effect.

                 4.16.2       There is no claim, suit, action or other
                              proceeding, including appeals and applications
                              for review, outstanding or pending or, to the
                              best of the Vendor's and the Corporation's
                              knowledge, threatened against the Corporation

                              knowledge, no facts or circumstances exist which
                              are reasonably likely to give rise to such a
                              claim, suit, action or other proceeding which
                              would have a Material Adverse Effect.

                 4.16.3       The Corporation has not caused the Release of any
                              Hazardous Substances on or from the Real

                              in such a manner or quantity as would not
                              constitute a violation of any of the
                              Environmental Laws or Environmental Permits or
                              would not reasonably be expected to result in a

                              of any fact or circumstance that is likely to

                              of any of the permits, licenses, certificates and

                              the Environmental Laws, which are necessary for
                              the Purchaser to conduct the Business
                              substantially as presently conducted.

                              Environmental Notice pursuant to any of the
                              Environmental Laws and, to the best of the
                              Corporation's and the Vendor's knowledge, there
                              are no facts or circumstances that would result

                              which would require that capital expenditures in
                              excess of $1,000,000 in the aggregate be made in
                              respect of the Business as a condition of
                              compliance with all of the Environmental Laws or
                              Environmental Permits, or (ii) to the effect that
                              any of the Environmental Permits is about to be

                 Agreement.

ARTICLE 5.       REPRESENTATIONS AND WARRANTIES OF THE PURCHASER

         The Purchaser represents and warrants to the Vendor as follows:

         5.1     INCORPORATION AND AUTHORIZATION 

                 The Purchaser is a corporation duly incorporated, organized,
                 validly existing and in good standing under the laws of
                 Georgia and has full capacity, power and authority, corporate
                 and otherwise, to execute, deliver and perform this Agreement
                 and consummate the transactions contemplated hereby, and has
                 been duly authorized to execute and become a party to this
                 Agreement and to consummate the transactions provided herein
                 or pursuant hereto.

         5.2     Enforceability of the Agreement

                 5.2.1        This Agreement constitutes a legal, valid and
                              binding obligation of the Purchaser enforceable
                              against it in accordance with its terms, except
                              that the enforcement hereof may be limited by
                              bankruptcy, insolvency, arrangement,
                              reorganization, moratorium or other similar laws
                              relating to creditors' rights generally and
                              general principles of equity (regardless of
                              whether enforceability is considered in a
                              proceeding in equity or at law).

                 5.2.2        Neither the entering into of this Agreement nor
                              the consummation by the Purchaser of any of the
                              transactions contemplated hereby shall, with
<PAGE>   47

                                      -42-

                              or without the giving of notice or the 
                              lapse of time, or both, result in the violation 
                              of any of the provisions of the articles of 
                              incorporation, articles of amendment, 
                              certificates in respect thereto, or by-laws of 
                              the Purchaser or of any written shareholders 
                              agreement or shareholders, stock or voting trust 
                              to which the Purchaser is a party or any Law to 
                              which the Purchaser is subject.

                 5.2.3        There are no judicial, quasi-judicial,
                              administrative, quasi-administrative or
                              arbitration proceedings pending against the
                              Purchaser which, if adversely determined, may
                              interfere with the purchase of or payment for the
                              Purchased Shares or the consummation of any of
                              the transactions herein provided.

         5.3     INVESTMENT REPRESENTATION

                 The Purchased Shares are purchased by the Purchaser for its
                 own account and not with a view to, or for sale in connection
                 with, any distribution thereof that would require registration
                 under the Securities Act, or any other Laws in respect of
                 securities, nor with any intention of reselling or granting
                 any participation in all or any part of the Purchased Shares
                 to any Person in a transaction that would violate the
                 Securities Act or any other Laws (including, without
                 limitation, those in respect of securities) or this Agreement.

         5.4     FINDER'S FEE

                 No Person has, or as a result of any of the transactions
                 contemplated hereby shall have, as a result of any commitment
                 of the Purchaser towards such Person, any right, interest or
                 claim against or upon the Vendor or any of its respective
                 properties for any commission, fee or other compensation as
                 broker or finder or for services in any similar capacity.

ARTICLE 6.       NON-COMPETITION

         6.1     NON-COMPETITION

                 From and after the Closing Date, neither Domtar nor the Vendor
                 shall, for a period of five (5) years, on its own behalf or on
                 behalf of any other Person, directly or indirectly, in any
                 capacity whatsoever including, without limitation, as
                 employer, principal, mandator, agent, mandatary, joint
                 venturer, partner, shareholder or other equity holder,
                 independent contractor, manufacturer, seller, licensor,
                 licensee, franchisor, franchisee, distributor, consultant,
                 supplier or trustee or by or through any Person, conduct 
<PAGE>   48

                                      -43-

                or be engaged in or have financial interests in any
                gypsum wallboard business in the United States of America or in
                Canada.  The Parties intend that the covenant contained in the
                preceding sentence of this Section 6.1 shall be construed as a
                series of separate covenants, one for each county and Province
                of the United States of America or Canada, as the case may be,
                and except for geographic coverage, each such separate covenant
                shall be deemed identical in terms to the covenant contained in
                the preceding sentence.  In the event that in any judicial
                proceeding, a court should refuse to enforce any of the
                separate covenants deemed included in this Section 6.1, it is
                the intent of the Parties that the breadth of such covenant be
                reduced to the maximum legally allowable parameters rather than
                such covenant being deemed totally unenforceable or invalid. 
                If such a reduction is not feasible, it is the intent of
                the Parties that the unenforceable covenant be deemed
                eliminated from these provisions for the purpose of those
                proceedings only to the extent necessary to permit the
                remaining separate covenants to be enforced.

         6.2     PERMITTED ACTIVITIES

                 Notwithstanding the provisions of Section 6.1 hereof, the
                 Vendor shall not be prohibited from owning an interest, as
                 passive investor, in any gypsum wallboard business provided
                 that the interest owned, whether directly or indirectly, by
                 the Vendor in such business, if any, shall not exceed 10% of
                 all the outstanding equity securities of any Person whose
                 equity securities are listed on a recognized securities
                 exchange and with whom the Vendor does not have any connection
                 whatsoever except for such ownership interest.

         6.3     LIMITED EXCEPTION FOR INCIDENTAL ACQUISITIONS

                 Notwithstanding the provisions of Section 6.1 hereof, neither
                 the Vendor nor Domtar shall be prohibited from acquiring
                 assets (or a controlling stock interest) of a Person where the
                 assets of such Person include gypsum wallboard assets (the
                 "ACQUIRED GYPSUM ASSETS"), provided that if the gross revenues
                 generated by Acquired Gypsum Assets during the last full
                 fiscal year period ("GROSS REVENUES") exceed $35,000,000, the
                 Vendor or Domtar, as the case may be (the "ACQUIROR"), shall
                 offer to sell the Acquired Gypsum Assets to the Purchaser.
                 Such offer to the Purchaser shall be made by the Acquiror
                 promptly upon the execution by the Acquiror of a binding
                 agreement to purchase such assets (but in no event less than
                 30 days prior to closing the acquisition contemplated by such
                 agreement).  If the Purchaser elects to purchase the Acquired
                 Gypsum Assets, the Acquiror and the Purchaser shall negotiate
                 in good faith the price to be paid by the Purchaser to the 
<PAGE>   49

                                      -44-

                 Acquiror for the Acquired Gypsum Assets.  If the
                 Acquiror and the Purchaser cannot agree upon the terms and
                 conditions of such sale, then the Acquiror shall use its
                 commercially reasonable efforts to sell the Acquired Gypsum
                 Assets to a third party within two years after negotiations
                 with the Purchaser cease, but no such sale shall be on terms
                 and conditions in the aggregate more favorable to the third
                 party than those offered to the Purchaser.  If the Gross
                 Revenues are less than or equal to $35,000,000, then the
                 Acquiror need not offer the Acquired Gypsum Assets to the
                 Purchaser, but if the Acquiror determines to sell the Acquired
                 Gypsum Assets prior to the fifth anniversary of the Closing,
                 the Acquiror shall first offer the Acquired Gypsum Assets to   
                 the Purchaser following the procedures set out in the
                 preceding sentences of this Section 6.3.

ARTICLE 7.       COVENANTS OF THE PARTIES

         The Parties, as specified in this Article 7, covenant and agree as
         follows:

         7.1     MAINTENANCE AND PRESERVATION OF BUSINESS

                 From and after the date hereof to the Closing Date or the date
                 of termination of the Parties' obligation to close under this
                 Agreement, the Vendor and the Corporation covenant to the
                 Purchaser that, except as may be specifically approved in
                 writing by the Purchaser, the Business will be conducted, and
                 the Corporation and KMHC will operate their respective
                 businesses, only in the ordinary course and substantially in
                 the same manner as presently conducted, will not make or
                 institute any new methods, principles or practices of
                 manufacture, purchase, sale, lease, management, accounting or
                 operation except in the ordinary course of business, and will
                 use their commercially reasonable efforts with due diligence
                 to (i) maintain their business organizations, and (ii)
                 maintain their relationships with and the goodwill of their
                 suppliers, distributors, licensors, customers and others
                 having business relations with them, so as to maintain the
                 goodwill and ongoing business of the Corporation.  By way of
                 illustration and not by way of limitation of the foregoing:

                 (A)          The Corporation shall manage its working capital,
                              including  receivables, other current assets,
                              trade payables and other current liabilities, in
                              a fashion consistent with past practice,
                              including by selling inventory and other property
                              in an orderly and prudent manner and paying
                              outstanding obligations, trade accounts and other
                              indebtedness as they come due.

                              condition and repair.

                 (C)          The Corporation shall not, without the prior
                              written approval of the Purchaser, take any of
                              the following actions:

                          (I)              dispose of any assets, other than
                                           (x) sales of inventory in the
                                           ordinary course of business and (y)
                                           Excluded Assets;

                          (II)             subject any of its assets to any 
                                           Lien, except Permitted Encumbrances;

                          (III)            make any payments to, or for the

                                           employee, director, officer or
                                           shareholder otherwise than at the
                                           regular rates payable to them, by
                                           way of salary, pension, bonus or
                                           other remuneration consistent with
                                           past practices for the Business;

                                           certificates in connection therewith
                                           or by-laws;

                                           money, or exchange, refund or renew
                                           any outstanding indebtedness in such
                                           a manner as to reduce the principal
                                           amount of such indebtedness and
                                           increase the rate or balance
                                           outstanding;

                                           combination with respect to, any of
                                           the Purchased Shares;

                          (VIII)           do any act or fail to do any act,
                                           where such act of failure to act
                                           will cause a breach of any
                                           representation, warranty or
                                           obligation contained in this
                                           Agreement or any obligation

                          (XI)             enter into any transaction,

                              Domtar and the Corporation

                              (a)     will take all reasonable measures to
                                      identify and make copies available to the
                                      Purchaser of all historical policies of

                              (b)     agree to make all reasonable and

                                      without limitation all casualty,
                                      liability and directors and officers
                                      coverages and shall give periodic status
                                      reports to the Purchaser concerning such
                                      attempts; and

                              (c)     agree not to release any insurance
                                      policies which provide or have provided
                                      coverage applicable to the Corporation or
                                      the Business without the prior written
                                      consent of the Purchaser.

                 7.4.2        The Vendor and the Purchaser acknowledge that the
                              policies of insurance applicable to the
                              Corporation are not necessarily exclusive to the
                              Corporation and that certain coverages and limits
                              may be impaired by claims arising from other
                              companies currently or previously owned by
                              Domtar; however, the Vendor will notify the
                              Purchaser of all such claims and impairment as
                              soon as reasonably practicable.  The Vendor and
                              Domtar make no representations or warranties in
                              respect of any policy of insurance and shall not
                              be responsible for any allocations,
                              determinations as to coverage or lack thereof or
                              any decision or interpretation made by insurers
                              or their agents with respect thereto.  The
                              Purchaser and the Corporation shall be
                              responsible for any retrospective premiums and
                              associated third party administrator and insurer
                              management and administration costs allocable to
                              the claims experience of the Corporation.  The
                              Purchaser recognizes and accepts that the Vendor
                              has in the past and may in the future compromise
                              rights and claims in good faith which may have an
                              effect on the consumption of aggregate insurance
                              limits and the allocation of retrospective
                              premiums.

                 7.4.3        As soon as practicable after the Closing Date,
                              but no later than thirty (30) Business Days after
                              the Closing Date, the Vendor and the Purchaser
                              shall enter into an agreement setting forth the
                              procedures for implementation and administration
                              of the entitlements and responsibilities provided
                              for by this Section 7.4.

         7.5     CORPORATE PROCEEDINGS FOR TRANSFER

                 The Vendor shall cause the Corporation to take all necessary
                 steps and proceedings as may be reasonably considered
                 appropriate by the Purchaser's Counsel in order that the
                 Purchased Shares be duly and regularly transferred to the
                 Purchaser as at the Effective Time.

                 the Purchaser for the preparation and filing of any Tax
                 Return, for the preparation for any tax audit or for the
                 prosecution or defence of any proceeding or proposed
                 adjustment with respect to taxes of the Corporation or the
                 Purchaser.

         7.9     OPERATION OF BUSINESS AFTER SECOND FIXTURE DATE

                 If the Closing does not occur on or before the Second Fixture
                 Date, the adjustment to the Purchase Price shall be determined
                 on the Second Fixture Date pursuant to Section 3.2 hereof.  In
                 such event, from and after the Second Fixture Date,

                 (i)      the Vendor and the Corporation covenant to the
                          Purchaser that, except as otherwise specifically

                          will be conducted, and the Corporation and KHMC will
                          operate their respective businesses, as provided in
                          Sections 7.1, 7.2, 7.3 and 7.4;

                              which Employee Plans are the Vendor Plans).  In
                              general, with respect to benefits provided by
                              such plans (except as may be otherwise
                              specifically provided in this Section 8.3), the
                              Vendor agrees to retain all benefits obligations

                              welfare plans shall be responsible for the
                              following benefits payments, subject to the terms
                              and conditions of particular plan:  (i) claims

                              Time.  In all cases, the amount and types of
                              benefits payable shall be determined in
                              accordance with the terms of the affected Vendor
                              Plan, and benefits payable for Employees shall be

                              requirements of Sections 401(a) and 401(k) of the

                              the Effective Time and adjusted as provided below
                              in this Section 8.3.5, in cash (and the notes
                              representing loans to the affected Employees),
                              equal to the total of the individual account
                              balances (the "ACCOUNT BALANCES") of the affected
                              Employees under the U.S. 401(k) Plan, reduced by
                              the amount of any distributions to the affected
                              Employees made in accordance with the terms of
                              the U.S. 401(k) Plan between the Effective Time
                              and the date of the transfer of such Employees'
                              Account Balances.  The Aggregate Account Balances
                              shall be increased or decreased by the amount of
                              any actual earnings or losses on each individual
                              account of the affected Employees included
                              therein from the Effective Time to the date of
                              the transfer of the Aggregate Account Balances,
                              which earnings or losses shall be credited or
                              debited to the appropriate accounts. The affected

                              U.S. 401(k) Plan at the Effective Time shall have
                              the right to periodically repay such loans in
                              accordance with their terms while such persons
                              are employed by the Purchaser.  Effective upon
                              the transfer of the Aggregate Account Balances to
                              the Purchaser's Savings Plans, the Purchaser and
                              such Purchaser's Savings Plans shall assume all
                              liabilities of the U.S. 401(k) Plan with respect
                              to such Aggregate Account Balances.  Prior to
                              such transfer, the Vendor shall be responsible
                              for the administration of the U.S. 401(k) Plan
                              accounts of participants whose accounts will be
                              transferred to the Purchaser's Savings Plans in
                              accordance with this Section 8.3.5 and shall
                              retain all fiduciary responsibility under ERISA
                              with respect to such funds.  The Purchaser and
                              the Vendor agree to cooperate in developing
                              procedures to facilitate the administration of
                              loans during the period between the Effective
                              Time and the date of the actual transfers and in
                              implementing the transfer of the Aggregate        
                              Account Balances as contemplated in this section.

                              8.4, the Vendor shall transfer or cause to be

                              all the benefits accrued by the Employees
                              (excluding, however, any Employee on Long-Term
                              Medical Leave) and Retired Employees under the
                              U.S. Plan up to the Effective Time, such transfer
                              to occur no later than ninety (90) Business Days

                 8.4.3        The Parties confirm that upon the completion of
                              the transfer contemplated in Section 8.4.2
                              hereof, the Vendor and the U.S. Plan shall be

                              obligations with respect to the pension benefits
                              accrued by the Employees and Retired Employees

                              said plans up to the Effective Time.  Prior to

                              U.S. Plan shall remain responsible for the

                              pursuant to Section 8.4.2 hereof, the Vendor

                              Employees and Retired Employees, and shall make
                              all benefits payments, under the U.S. Plan and
                              the Amounts shall be adjusted accordingly as at
                              the date of the actual transfer.

                 8.4.7        The Vendor shall not make, without the prior
                              written consent of the Purchaser, any
                              modification to the U.S. Plan between the
                              Effective Time and the date of the actual
                              transfer of the Amounts (the "TRANSITIONAL
                              PERIOD"), if such modifications would change in
                              any way the terms and conditions affecting the
                              accrued benefits to be transferred to the
                              Purchaser's Employee Plans (including for greater
                              certainty, but without limitation the benefits of
                              the affected Employees and Retired Employees or
                              the contributions with respect to such benefits)
                              or would otherwise affect the calculation of the
                              Amounts.  Notwithstanding anything in this
                              Section 8.4.7 to the contrary, if a change
                              proposed by the Vendor is mandated by the Law,
                              the Vendor need not obtain the Purchaser's prior
                              approval (but prior notice is still required)
                              unless the latest effective date of the change
                              permitted by Law (as applied to the Vendor
                              Pension Plan in question) falls more than sixty
                              (60) days after the date on which the requirement
                              of the Law was first published or the requirement
                              of the Law may be satisfied in more than one way.

                 8.4.8        For the purpose of Section 8.4.2 hereof, the
                              Amounts shall equal the projected benefit
                              obligation in respect of the accrued benefits as
                              of the Effective Time of the affected Employees
                              and Retired Employees.  The Amounts shall be
                              determined as at the Effective Time using the
                              same funding actuarial methods and assumptions
                              used in the actuarial valuations of the U.S. Plan
                              as at January 1, 1995.

                              Initial calculations shall be performed by the
                              Vendor's actuary using the actuarial assumptions
                              and the methods referred to in this Section 8.4.8
                              within six (6) months after the Effective Time
                              and shall be submitted for review and approval to
                              the Purchaser's actuary.  The Purchaser's

                                      -56-

                              actuary shall have sixty (60) days to review the
                              calculations and report back to the Parties.  If
                              the Purchaser's actuary contests the Vendor's
                              actuary's calculations, a final determination
                              shall be made by an independent third party
                              actuary acceptable to the Parties, and each Party
                              shall be responsible for one half of the cost of
                              such final determination by such independent
                              third party actuary.

                 8.4.9        During the Transitional Period, the Amounts and
                              all adjustments thereof shall be adjusted as
                              follows:

                          (i)              for the period ending on the date of
                                           determination of the last known rate
                                           of return of the pension fund of the
                                           relevant Vendor's Pension Plan (the
                                           "INITIAL PERIOD"), the rates of
                                           return of the pension fund of said
                                           relevant Vendor's Pension Plan; and

                          (ii)             from the end of the Initial Period
                                           to the date of the actual transfer
                                           of the Amounts, at the investment
                                           return rate used in the actuarial
                                           assumptions referred to in Section
                                           8.4.8.

                              The transfer of the Amounts and the adjustments
                              shall be made in kind and in cash as determined
                              in SCHEDULE 8.4.9.  If any portion of the Amounts
                              is transferred in kind, the assets shall be
                              valued for purposes of the transfer at the market
                              value as of the close of business on the market
                              day immediately preceding the transfer.

                 8.4.10       The Vendor shall indemnify and hold the Purchaser
                              and the Purchaser's Employee Plans against any
                              claims, liabilities and expenses (including, for
                              greater certainty and without limitation,
                              attorney's fees) arising from the failure of the
                              U.S. Plan or the U.S. 401(k) Plan to be in
                              compliance with applicable Law (including,
                              without limitation, those pertaining to
                              qualification standards and favorable tax
                              treatment of qualified plans) at the time of the
                              assets transfers contemplated in Sections 8.3.5
                              and 8.4.

         8.5     AFFIDAVITS FOR TITLE INSURANCE

                 The Corporation will cooperate with the Purchaser with respect
                 to obtaining real property title insurance in accordance with
                 Section 10.1.6, including providing owner's affidavits and
                 taking other actions as may reasonably be requested by the
                 Purchaser.

         8.6     NO INTERFERENCE

                 The Purchaser shall not take any action prior to the Closing
                 which would negatively impact the ability of the Vendor and
                 the Corporation to operate the Business or to comply with
                 their obligations under Section 7.1 or other provisions of
                 this Agreement.  After the Closing, the Parties shall
                 cooperate and not interfere with one another in the efforts of
                 Domtar, the Vendor and Public Service Electric & Gas to
                 clean-up the Camden facility under the Administrative Consent
                 Order issued under the New Jersey Environmental Clean-up
                 Responsibility Act, as amended, and related statutes, with due
                 allowance for the operation of the facility.

         8.7     GUARANTEES, LETTERS OF CREDIT, ETC.

                 (a)      The Vendor and Domtar will use their reasonable
                          efforts to replace, renew or extend any surety bonds,
                          letters of credit or corporate guarantees previously
                          provided by the Vendor or Domtar which are required
                          to operate the Business in the ordinary and usual
                          course and to preserve in all material respects the
                          Business intact (the "SUPPORT INSTRUMENTS").  The
                          Vendor and Domtar shall continue any such
                          arrangements with respect to the Business until the
                          Purchaser obtains such surety and letter of credit
                          arrangements with existing or replacement surety
                          companies or financial institutions or provides
                          substitute guarantees (but in any event such
                          obligation shall not continue for a period exceeding
                          6 months from Closing).

                 (b)      The Purchaser shall (i) reimburse the Vendor for the
                          cost of the Support Instruments continued after the
                          Closing Date, (ii) indemnify and hold harmless the
                          Vendor with respect to all Support Instruments in
                          existence at the Closing Date or thereafter with
                          respect to the Business, and (iii) promptly undertake
                          to have the Vendor and Domtar released from all such
                          Support Instruments, in each case to the extent they
                          relate to the Business.

         9.1     OBTAINING APPROVALS

                 The Purchaser and the Vendor shall prepare and file promptly,
                 with all reasonable diligence, all notifications, forms,
                 reports and other documents, and shall take and complete
                 promptly, with all reasonable diligence, all steps, measures

                 and procedures, as may be required by any federal,
                 state, provincial or local governmental authority, as the case
                 may be (the "ANTITRUST AUTHORITY"), for the purpose of
                 obtaining all permits, consents, orders or approvals required
                 under the applicable federal, state, provincial or local
                 antitrust and competition laws (the "ANTITRUST LAWS")
                 including, without limitation, the HSR Act, for the purpose of
                 the consummation of the transaction contemplated hereby;
                 provided that the Vendor shall not be obligated to modify the
                 scope or terms of the transaction or to undertake any
                 obligations with respect to the Corporation or any Subsidiary
                 thereof or the assets of any thereof beyond those already
                 required by other sections of this Agreement.  Without
                 limiting the generality of the foregoing provisions of this
                 Section, the Purchaser shall:

                 9.1.1        take promptly, with all reasonable diligence, any
                              and all of the following actions to the extent
                              reasonably required to eliminate any objections
                              on the part of any Antitrust Authority regarding
                              the legality under any Antitrust Law of the
                              Purchaser's acquisition of the Purchased Shares
                              in accordance with the terms of this Agreement,
                              namely, making proposals, executing and carrying
                              out agreements and submitting to judicial or
                              administrative orders, providing for the sale or
                              other disposition, or the holding separate
                              (though the establishment of a trust or
                              otherwise) of particular assets or categories  of
                              assets or businesses of any of the Purchaser and
                              the Corporation or any Subsidiary thereof, as the
                              case may be, or, pending completing of any of the
                              foregoing actions, the holding separate (through
                              the establishment of a trust or otherwise) of the
                              voting securities of the Corporation or any
                              Subsidiary thereof, as the case may be;

                 9.1.2        use all reasonable efforts to prevent the entry
                              in a judicial or administrative proceeding
                              brought under any Antitrust Law by any Antitrust
                              Authority of any permanent or preliminary
                              injunction or other order that would make the
                              consummation of the acquisition of the Purchased
                              Shares in accordance with the terms of this
                              Agreement unlawful or would prevent or
                              unreasonably delay it, including, without
                              limitation, taking the steps contemplated in
                              Section 9.1.1;

                 9.1.3        take promptly, with all reasonable diligence, in
                              the event that such an injunction or order has
                              been issued in such a proceeding, any and all
                              steps, including, without limitation, appeal
                              thereof, the posting of a bond or the steps

                              contemplated in Section 9.1.1, necessary to
                              vacate, modify or suspend such injunction or
                              order so as to permit the consummation of the
                              acquisition of the Purchased Shares in accordance
                              with the terms of this Agreement as nearly as
                              possible on the timetable contemplated by this
                              Agreement; and

                 9.1.4        take promptly, with all reasonable diligence, all
                              other actions and do all other things reasonably
                              necessary and proper to avoid or eliminate each
                              and every impediment under any Antitrust Law
                              which may be asserted by any Antitrust Authority,
                              to the consummation of the acquisition of the
                              Purchased Shares in accordance with the terms of
                              this Agreement.

         9.2     DEALINGS WITH AUTHORITY

                 Nothing in this Agreement shall be deemed to limit the ability
                 of the Purchaser to contest, in any appropriate administrative
                 or judicial forum, any effort of any Antitrust Authority to
                 require the divestiture by the Purchaser of particular assets
                 or categories of assets or businesses of any of the Purchaser
                 and the Corporation or any Subsidiary thereof, or the holding
                 separate (through establishment of a trust or otherwise) of
                 the voting securities of the Corporation or any Subsidiary
                 thereof; provided, however, that the Purchaser shall take such

                 11.5.1       Promptly upon receipt by either Party (the
                              "INDEMNITEE") of a notice of any Third Party
                              Claim in respect of which Indemnitee proposes to
                              demand indemnification from the other Party (the
                              "INDEMNITOR"), the Indemnitee shall give notice
                              to that effect to the Indemnitor with reasonable
                              promptness.

                 11.5.2       Without prejudice to the Indemnitee's right to
                              participate in the defense, compromise or
                              settlement of the Third Party Claim, the
                              Indemnitor shall have the right by notice to the
                              Indemnitee not later than ten (10) days after
                              receipt of the notice described in Section 11.5.1
                              hereof to assume (and in the case of asbestos
                              claims, shall assume) the control of the defence,
                              compromise or settlement of the Third Party
                              Claim, provided that such assumption shall, by
                              its terms, be without cost or liability to the
                              Indemnitee and provided that the Indemnitor shall
                              have first delivered to Indemnitee a written
                              acknowledgement by Indemnitor that the relevant
                              Claim is an Indemnified Claim and that the
                              Indemnitor, in its good faith judgment, will be
                              able to pay any award of money damages against
                              the Indemnitee in connection with such action.
                              If the Indemnitor assumes the defense of an
                              action, (i) the Indemnitee shall be entitled to
                              meaningfully participate therein; (ii) no
                              settlement or compromise thereof may be effected
                              (x) by the Indemnitor without the consent of the
                              Indemnitee (which consent shall not be
                              unreasonably withheld or delayed) unless (A)
                              there is no finding or admission of any violation
                              of law or any violation of the rights of any 
<PAGE>   75

                                      -70-

                              person by Indemnitee and no adverse effect on any
                              other claims that may be made against any
                              Indemnitee and (B) all relief provided is paid or
                              satisfied in full by the Indemnitor or (y) by the
                              Indemnitee without the consent of the Indemnitor;
                              and (iii) the Indemnitee may subsequently assume
                              the defense of such action if a court of
                              competent jurisdiction determines the Indemnitor
                              is not vigorously defending such action.

                 11.5.3       Upon the assumption of control by the Indemnitor
                              pursuant to the provisions of Section 11.5.2
                              hereof, the Indemnitor shall, at its expense,
                              diligently proceed with the defence, compromise
                              or settlement of the Third Party Claim at
                              Indemnitor's sole expense, including employment
                              of counsel reasonably satisfactory to the
                              Indemnitee and, in connection therewith, the
                              Indemnitee shall cooperate fully, but at the
                              expense of the Indemnitor, to make available to
                              the Indemnitor all pertinent information and
                              witnesses under the Indemnitee's control, make
                              such assignments and take such other steps as in
                              the opinion of counsel for the Indemnitor are
                              necessary to enable the Indemnitor to conduct
                              such defence.

                 11.5.4       The final determination of any such Third Party
                              Claim, including all related costs and expenses,
                              shall be binding and conclusive upon the Parties
                              as to the validity or invalidity, as the case may
                              be, of such Third Party Claim against the
                              Indemnitor.

                 11.5.5       Should the Indemnitor fail to defend the
                              Indemnitee as provided in Section 11.5.2 hereof,
                              the Indemnitee shall be entitled to make such
                              settlement of the Third Party Claim as in its
                              sole discretion may appear advisable, and such
                              settlement or any other final determination of
                              the Third Party Claim shall be binding upon the
                              Indemnitor.

                            its insurers and any and all recoveries from any

                            The Indemnitee shall use all reasonable efforts to
                            collect such insurance proceeds or, if the
                            Indemnitee is the Purchaser, claims with respect to

                            in this Section 11.6 shall require any Indemnitee
                            to make or prosecute a claim for insurance proceeds
                            if such a claim would adversely affect the
                            Indemnitee  with respect to matters other
                            than the Claim.

                            deducted from the amount so claimed pursuant to
                            this Article 11 the amount of the respective

                            retained by the Corporation after the Closing Date,

                              and the amount then claimable shall be only the
                              amount of such Claims which exceeds 1% of the
                              Purchase Price.

                 11.7.2       Subject to the provisions of Sections 11.3.2,

                              of the Purchase Price an amount equal to the
                              difference between 10% of the Purchase Price and
                              the aggregate of the Claims indemnified against

                              that the Purchaser shall not exercise its right

                              amount of 1% of the Purchase Price, and the
                              amount then claimable shall be only the amount of
                              such Environmental Claims which exceeds 1% of the
                              Purchase Price; and provided further that the
                              combined amount recoverable under Section 11.7.1
                              and 11.7.2 shall not exceed in the aggregate 25%
                              of the Purchase Price.

                 With respect to any Claim pursuant to Section 11.3 or 11.4

                 rise to the Claim coming to the attention of the Indemnitee
                 hereunder; provided that failure to so notify the Indemnitor
                 shall not relieve the Indemnitor from any liabilities which it
                 may have to the Indemnitee (i) hereunder, except to the extent
                 that is actually prejudiced thereby, or (ii) otherwise than

                              executed stock powers for transfer thereof; and

                 12.1.2       all such other agreements, certificates,
                              consents, approvals, opinions and other documents

ARTICLE 13.      TERMINATION

         13.1    ELECTION

                 The Parties shall exercise all reasonable efforts and
                 cooperate, with reasonable diligence, in order for the
                 consummation of the transactions contemplated hereunder to
                 take place at the earliest possible date.  Subject to the
                 provisions of Section 10.1.12 or 10.2.8 hereof, as the case
                 may be, in the event that the sale and purchase of the
                 Purchased Shares herein provided for is not consummated within
                 five (5) months from the date of this Agreement (the
                 "FIVE-MONTH ANNIVERSARY") as a result of the failure of either
                 Party to fulfill any of the conditions provided for in Section
                 10.1 (other than those contained in Section 10.1.3 to the 
<PAGE>   79

                                      -74-

                 extent covered by Article 9) or 10.2, as the case may be, for
                 the benefit of the other Party on or before the Five-Month
                 Anniversary and the Party who has the benefit of such
                 condition (the "ELECTING PARTY") refuses to waive it, the
                 Electing Party shall have the right, exercisable at any time
                 after the Five-Month Anniversary, to terminate this Agreement
                 by giving at least forty-five (45) days written notice to the
                 other Party (the "NON-ELECTING PARTY").  For purposes of this
                 Article 13, Domtar and the Corporation shall be deemed the
                 same Party as the Vendor.  If the Non-Electing Party does not
                 cure its failure to fulfil the conditions of Sections 10.1 or
                 10.2, as the case may be, by the date for termination (the
                 "TERMINATION DATE") specified in the termination notice given
                 by the Electing Party, then this Agreement shall terminate on
                 the Termination Date, and, except as set forth in Section
                 13.2,  each Party shall be released from

                 13.1.1       all obligations whatsoever to whomsoever
                              including, without limitation, all obligations to
                              the other Party, its Affiliates and Subsidiaries
                              and their respective shareholders, directors,
                              officers and employees, pursuant to this
                              Agreement and all other agreements entered into
                              pursuant hereto; and

                 13.1.2       all Claims arising out of, directly or
                              indirectly, the failure to consummate the sale
                              and purchase of the Purchased Shares as herein
                              provided for.

         13.2    CONTINUING LIABILITY

                 For purposes of Section 13.1, the responsibility for obtaining
                 any permits, consents, orders or approvals referred to in
                 Article 9 shall be that solely of the Purchaser.  If this
                 Agreement is terminated by Vendor under Section 13.1 effective
                 as of a date after the Second Fixture Date because of the
                 breach by the Purchaser of its obligations under Article 9,
                 then the Purchaser shall remain liable to the Vendor for the
                 failure to consummate the sale and purchase of the Purchased
                 Shares as herein provided.
