Dear Zemex shareholder
    
 
   
We are calling a special meeting for you to vote on a reincorporation merger
that would change the company's domicile from the United States to Canada. If we
complete the merger, you will own shares in a new Canadian corporation called
Zemex Canada, and Zemex will become a subsidiary of Zemex Canada. We believe
that the reincorporation in Canada will enable us to benefit from an active
trading market in Canada for Canadian natural resources companies.
    
 
   
Zemex common stock is currently listed for trading on the New York Stock
Exchange under the symbol "ZMX". Following the merger, the shares of Zemex
Canada are expected to be listed on the New York Stock Exchange and The Toronto
Stock Exchange, and Zemex common stock will no longer be listed or traded on any
exchange.
    
 
   
The Board of Directors recommends that you vote in favor of the reincorporation.
Dundee Bancorp International Inc, which holds approximately 34% of the
outstanding shares, and members of the Board of Directors, who own approximately
12% of the outstanding shares, have indicated that they intend to vote for the
approval of the merger agreement.
    
 
   
We are calling a special meeting of the shareholders to vote on the
reincorporation and are soliciting proxies for use at the meeting. The record
date for voting at the meeting is December 14, 1998. The meeting will be held:
    
 
   
                                     , January   , 1999

THIS SUMMARY PROVIDES AN OVERVIEW OF THE INFORMATION CONTAINED IN THIS PROXY
STATEMENT/ PROSPECTUS AND DOES NOT CONTAIN ALL THE INFORMATION YOU SHOULD
CONSIDER. THEREFORE, YOU SHOULD ALSO READ THE MORE DETAILED INFORMATION SET
FORTH IN THIS DOCUMENT, THE FINANCIAL STATEMENTS OF THE COMPANY AND THE OTHER
INFORMATION THAT IS INCORPORATED BY REFERENCE. THE SYMBOL "$" REFERS TO UNITED
STATES DOLLARS.
 
                                 THE COMPANIES
 
ZEMEX
 
Zemex Corporation was incorporated in 1985 in Delaware as the successor to
Pacific Tin Corporation. Zemex is a niche producer of industrial minerals and
metal products. Its principal businesses are industrial minerals, metal powders
and aluminum dross recycling. Its major products include feldspar, feldspathic
minerals, kaolin, sand, mica, talc, ferrous and non ferrous powders and aluminum
dross derivatives. Zemex's principal offices are located at Canada Trust Tower,
BCE Place, 161 Bay Street, Suite 3750, Toronto, Ontario, Canada M5J 2S1 and its
telephone number is (416) 365-8080.
 
ZEMEX CANADA
 
   
Zemex Canada Corporation was incorporated in 1997 under the Canada Business
Corporations Act to facilitate the change of domicile of Zemex from Delaware to
Canada. After the merger, Zemex shareholders will own the common shares of Zemex
Canada, in the same relative proportions as their ownership of Zemex prior to
the merger, and Zemex will become a wholly-owned subsidiary of Zemex Canada.
Zemex Canada will continue to conduct the business in which Zemex is currently
engaged. Zemex Canada's registered office is located at Canada Trust Tower, BCE
Place, 161 Bay Street, Suite 3750, Toronto, Ontario, Canada M5J 2S1, and its
telephone number is (416) 365-8080.
    
 
                        REINCORPORATION MERGER PROPOSAL
 
   
OVERVIEW OF THE PROPOSAL
    
 
   
The board of directors of Zemex has determined that it is advisable to change
Zemex's domicile from Delaware to Canada and proposes to effect the change of
domicile through the proposed merger. After the merger, each share of Zemex
common stock that you own will be changed into one common share of Zemex Canada,
and Zemex will become a wholly-owned subsidiary of Zemex Canada. The change of
domicile will not result in any material change to the business of Zemex and
will not have any effect on your relative equity or voting interests in the
Zemex business. The change of domicile will, however, result in changes in your
rights and obligations under applicable corporate laws. In addition, the merger
may have tax consequences for you. For example, some shareholders may recognize
a taxable gain in the merger.
    
 
   
PURPOSES AND EFFECTS OF THE CHANGE OF DOMICILE
    
 
   
The Board of Directors believes reincorporation in Canada will enable
shareholders to benefit from an active trading market in Canada for Canadian
natural resources companies, such as Zemex. The Board also expects the dual
listing of Zemex Canada common shares on the New York Stock Exchange and The
Toronto Stock Exchange to enhance liquidity for shareholders by creating a
broader and deeper trading market.
    
 
                                      -1-
<PAGE>
   
VOTE REQUIRED FOR APPROVAL
    
 
   
Approval of the merger agreement requires the affirmative vote of the
shareholders of Zemex holding at least a majority of the outstanding shares of
Zemex common stock. The directors and executive officers of Zemex together
directly owned approximately 12% of the total number of outstanding shares of
Zemex common stock. Dundee Bancorp International Inc. owns approximately 34% of
the outstanding shares of Zemex common stock. These shareholders have indicated
that they intend to vote all their shares for the approval of the merger
agreement.
    
 
   
DISSENTERS' RIGHTS
    
 
   
Delaware law grants to shareholders appraisal rights which entitle shareholders
to receive payment of the fair value of their shares in certain corporate
transactions, such as a merger. However, Zemex shareholders will not have
appraisal rights in connection with the reincorporation merger because Zemex
common stock was listed on the New York Stock Exchange prior to the merger and
Zemex Canada common shares also will be listed on the exchange following the
merger.
    
 
   
RISK FACTORS
    
 
   
Factors such as possible adverse tax consequences and stock price volatility of
the Zemex Canada common shares following the merger may affect your vote on the
merger and your interest in owning shares of Zemex Canada. In evaluating Zemex
Canada and its business, you should carefully consider the risk factors and the
other information included or incorporated by reference in this proxy
statement/prospectus.
    
 
   
MATERIAL TAX CONSEQUENCES
    
 
   
The following is a brief summary of the material tax consequences of the
reincorporation merger. Shareholders should consult their own tax advisers with
respect to their particular circumstances. A more detailed summary of the
factors affecting the tax consequences of the reincorporation merger is set out
under "Material United States Federal Tax Consequences" and "Material Canadian
Federal Income Tax Consequences."
    
 
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
    - Holders of Zemex common stock who are treated as U.S. persons for U.S.
      Federal income tax purposes will recognize gains but not losses on their
      Zemex common stock.
 
   
    - Holders of Zemex common stock who are treated as foreign persons for U.S.
      Federal income tax purposes, including holders who hold directly and
      constructively more than 5% of the outstanding Zemex common stock, will
      not recognize taxable gain or loss on their Zemex common stock.
    
 
CANADIAN FEDERAL INCOME TAX CONSEQUENCES
 
    - Holders of Zemex common stock who are resident or are deemed to be
      resident in Canada for purposes of the Income Tax Act (Canada) who
      exchange their Zemex common stock for Zemex Canada common shares will be
      considered to have disposed of their Zemex common stock for proceeds of
      disposition equal to the fair market value of Zemex Canada common shares
      received in exchange.
 
    - Holders who are neither resident nor deemed to be resident in Canada for
      purposes of the Income Tax Act (Canada) and who do not use or hold their
      Zemex common stock or Zemex Canada common shares in connection with
      carrying on business in Canada will incur no tax liability under the
      Income Tax Act (Canada) on any capital gain
 
                                      -2-
<PAGE>
   
      realized on the disposition of Zemex common stock in exchange for Zemex
      Canada common shares.
    
 
COMPARATIVE RIGHTS OF SHAREHOLDERS
 
The principal attributes of Zemex common stock and Zemex Canada common shares
will be identical in all material respects. However, the rights of shareholders
under Delaware law differ in certain substantive ways from the rights of
shareholders under the Canada Business Corporations Act. Examples of some of the
changes in shareholder rights which will result from reincorporation are:
 
    - Shareholders holding at least 5% of the shares entitled to vote may
      require the board to call a special meeting of shareholders under Canadian
      law. Delaware law does not contain a similar requirement.
 
    - Shareholder actions by written consent are only valid under Canadian law
      when all of the shareholders entitled to vote on the matter sign the
      written consent. Delaware law requires the signatures of only a majority
      of such shareholders for a valid action by written consent.
 
    - Dissenter's rights are available to shareholders under more circumstances
      under Canadian law than under Delaware law.
 
    - Shareholders have a statutory oppression remedy under Canadian law that
      does not exist under Delaware statute. It is similar to the common law
      action in Delaware for breach of fiduciary duty, but the Canadian remedy
      does not require shareholders to prove that the directors acted in bad
      faith.
 
    - A majority of the directors of a Canadian company must reside in Canada.
      Delaware law does not contain a similar provision.
 
   
    - A director's liability may not be limited under Canadian law as it may
      under Delaware law.
    
 
   
ACCOUNTING TREATMENT
    
 
   
The indirect acquisition by Zemex Canada of the assets and liabilities of Zemex
in connection with the reincorporation merger will be accounted for as a
statutory reincorporation. There will not be any "step-up" or write-up of assets
for accounting purposes as a result of the reincorporation merger. We have not
included pro forma financial information to show how the financial statements
would appear if the merger had already occurred because the pro forma financial
information would not differ substantially from the historical financial
information. The carrying values of the assets and liabilities of Zemex Canada
after the transaction will substantially reflect the carrying values of the
assets and liabilities of Zemex prior to the transaction.
    
 
   
RECOMMENDATION OF THE ZEMEX BOARD OF DIRECTORS
    
 
   
TAKING INTO CONSIDERATION ALL OF THE FACTORS AND REASONS FOR THE MERGER SET
FORTH ABOVE AND ELSEWHERE IN THIS PROXY STATEMENT/PROSPECTUS, THE ZEMEX BOARD OF
DIRECTORS HAS APPROVED THE MERGER AGREEMENT AND RECOMMENDS THAT SHAREHOLDERS OF
ZEMEX VOTE FOR APPROVAL OF THE MERGER AGREEMENT.

                             SUMMARY FINANCIAL DATA
 
   
THE FOLLOWING SUMMARY FINANCIAL INFORMATION FOR THE YEARS 1993 THROUGH 1997
INCLUDES BALANCE SHEET AND STATEMENT OF OPERATIONS DATA FROM THE AUDITED
CONSOLIDATED FINANCIAL STATEMENTS OF ZEMEX. THE FOLLOWING SUMMARY FINANCIAL
INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1998 AND 1997 INCLUDES
BALANCE SHEET AND STATEMENT OF OPERATIONS DATA FROM UNAUDITED HISTORICAL
CONSOLIDATED FINANCIAL STATEMENTS OF ZEMEX. IN THE OPINION OF MANAGEMENT, THE
UNAUDITED FINANCIAL STATEMENTS REFLECT ALL ADJUSTMENTS (CONSISTING OF NORMAL
RECURRING ADJUSTMENTS) NECESSARY FOR A FAIR STATEMENT OF RESULTS FOR THE
UNAUDITED INTERIM PERIODS. THE INFORMATION CONTAINED IN THIS TABLE SHOULD BE
READ IN CONJUNCTION WITH "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS" AND THE CONSOLIDATED FINANCIAL STATEMENTS
AND ACCOMPANYING NOTES INCLUDED IN THE 1997 FORM 10-K, THE 1997 FORM 10-K/A-1,
THE MARCH 31, 1998 FORM 10-Q , THE JUNE 30, 1998 FORM 10-Q AND THE SEPTEMBER 30,
1998 FORM 10-Q THAT ARE INCORPORATED BY REFERENCE.
    
 
The financial statements of Zemex have been prepared in accordance with
accounting principles generally accepted in the United States. The application
of Canadian generally accepted accounting principles, which will be applicable
to Zemex Canada's financial statements, would not result in any material

                                  RISK FACTORS
 
An investment in Zemex Canada common shares involves certain risks. In
evaluating Zemex Canada and its business, investors should carefully consider
the following risk factors in addition to the other information included or
incorporated by reference in this proxy statement/prospectus.
 
   
              RISK FACTORS RELATING TO THE REINCORPORATION MERGER
    
 
   
TAX CONSEQUENCES TO SHAREHOLDERS--U.S. SHAREHOLDERS WILL RECOGNIZE GAIN ON THEIR
ZEMEX COMMON STOCK AND MAY BE SUBJECT TO CANADIAN WITHHOLDING TAXES FOR ANY
DIVIDENDS PAID AFTER THE MERGER.
    
 
   
Generally, for U.S. Federal income tax purposes, the reincorporation merger will
cause shareholders of Zemex common stock who are taxable as U.S. persons to
recognize gains, but not losses, on their Zemex common stock. For further
explanation, see "Material United States Federal Tax Consequences." Any
dividends that are paid to United States holders of Zemex Canada common shares
after the reincorporation merger may be subject to Canadian withholding taxes at
the rate of 15% for holders who own less than 10% of Zemex Canada voting stock.
For further explanation, see "Material Canadian Federal Income Tax
Consequences." In addition, payments of dividends or interest by Zemex to Zemex
Canada could also be subject to United States withholding taxes at rates of 15%
and 10%, respectively.
    
 
   
VOLATILITY OF STOCK PRICE--THE STOCK PRICE OF ZEMEX CANADA COMMON SHARES MAY BE
VOLATILE. IN ADDITION, DEMAND IN THE UNITED STATES FOR ZEMEX CANADA COMMON
SHARES MAY BE DECREASED BY THE CHANGE IN DOMICILE.
    
 
The market price of Zemex Canada common shares may be subject to significant
fluctuations in response to variations in results of operations and other
factors. Developments affecting the specialty materials industry generally,
including national and international economic conditions, currency fluctuations
and government regulation, could also have a significant impact on the market
price of the Zemex Canada common shares. In addition, in recent years, the stock
market has experienced a high level of price and volume volatility and market
prices for the stock of many companies have experienced wide price fluctuations
which have not necessarily been related to the operating performance of such
companies. These broad market fluctuations, which are beyond the control of
Zemex Canada, could have a material adverse effect on the market price of Zemex
Canada common shares.
 
Prior to the reincorporation merger, there has been no public market for Zemex
Canada common shares (although there has been a public market for the Zemex
common stock). Zemex Canada cannot predict what effect the reincorporation will
have on the market price prevailing from time to time or the liquidity of Zemex
Canada common shares. While the Zemex common stock has been and Zemex Canada
common shares will be listed for trading on the New York Stock Exchange, the
change in domicile and expected increase in investment interest in Canada may
decrease the demand for Zemex Canada common shares in United States trading
markets. The decrease may not be offset by increased demand on The Toronto Stock
Exchange.
 
                                      -5-
<PAGE>
RESTRICTIONS ON FREE TRANSFER OF ZEMEX CANADA COMMON SHARES IN CANADA
 
Zemex Canada common shares to be issued to shareholders resident in certain
provinces of Canada will be subject to restrictions imposed by law that limit
the ability of a shareholder to resell such securities within such province. As
an example, shareholders resident in the Province of Ontario will be subject to
restrictions on resale of their Zemex Canada common shares in Ontario until
Zemex has been listed on the Toronto Stock Exchange for over one year.
Additionally, any person, company or combination of persons or companies holding
a sufficient number of Zemex Canada common shares to affect materially the
control of Zemex Canada will be restricted in selling Zemex Canada common shares
pursuant to securities laws applicable in Canada.
 
                RISK FACTORS RELATING TO ZEMEX CANADA'S BUSINESS
 
   
VULNERABILITY TO ECONOMIC CYCLES--RECESSION COULD REDUCE PRODUCT DEMAND.
    
 
   
Zemex Canada's future operating results will depend largely upon the economic
environments in which it operates. In the past, recessionary pressures in the
housing, automotive, construction, transportation and durable goods industries
have adversely affected demand for Zemex's products. Zemex Canada expects that
product demand (and consequently results of operations) will continue to be
highly sensitive to North American economic conditions and other factors beyond
Zemex Canada's control.
    
 
   
ACQUISITION DUE DILIGENCE RISKS--ZEMEX CANADA MAY BECOME RESPONSIBLE FOR
ENVIRONMENTAL AND OTHER LIABILITIES IN CONNECTION WITH AN ACQUISITION.
    
 
   
Acquisition of specialty materials businesses has been a key element of Zemex's
success, and Zemex Canada will continue to seek acquisitions in the future.
Zemex has performed and Zemex Canada will continue to perform reviews of the
operations to be acquired that it believes is consistent with industry
practices. However, such reviews are inherently incomplete. In addition,
representations, warranties and indemnities received from sellers may not be
adequate to limit acquisition risks. It is generally not feasible to review
in-depth all of the operations and records of an acquired business. Ordinarily,
Zemex Canada will focus most of its due diligence efforts on the operation's
more significant assets. However, even an in-depth review of operations and
records may not necessarily reveal existing or potential problems, nor will it
permit a buyer to become familiar enough with the operations to assess fully
their deficiencies and capabilities. Moreover, environmental problems, such as
ground water contamination, are not necessarily observable even when an in-depth
inspection is undertaken. Zemex Canada may become responsible for environmental
and other liabilities in connection with acquired assets and operations.
    
 
   
MARKET RISK OF SUBSTITUTE PRODUCTS--THE DISCOVERY OR DEVELOPMENT OF SUBSTITUTE
INDUSTRIAL MINERAL PRODUCTS COULD ADVERSELY AFFECT ZEMEX CANADA'S MARKET SHARE
AND RESULTS OF OPERATIONS.
    
 
Zemex Canada believes that there are few current effective substitutes for
Zemex's industrial mineral products (e.g., feldspar, talc and mica). With
respect to feldspar, substitute products exist for use in the ceramics industry,
but their use has been accompanied by product quality problems. With respect to
talc and mica, substitute products are continually being developed for use in
the plastics industry, but Zemex continues to engage in research to ensure that
its products provide the most satisfactory product performance. If alternative
products are
 
                                      -6-
<PAGE>
discovered or developed to a stage of competitive price and performance level,
they could potentially erode Zemex Canada's market share and adversely affect
results of operations.
 
COMPETITION FOR SALES IN SPECIALTY MATERIALS INDUSTRY
 
The specialty materials industry is highly competitive. Zemex Canada will
compete for acquisitions and in the development, production and marketing of
specialty materials with other companies. The markets for talc and metal powders
products are dominated by several large competitors of Zemex, and are
characterized by competition in price and product development. Zemex Canada
competes for sales in its Alumitech operations based principally upon
technological know-how. While Zemex believes it has a dominant market position
in its feldspar and mica operations, competition in that market is based on
price, quality and development of new product applications. Some of the
competitors of Zemex Canada have substantially greater financial and other
resources than Zemex Canada. Zemex Canada cannot be certain that competitors
will not succeed in developing products based upon new processor technologies
that are more effective or less expensive than Zemex Canada's products.
 
   
BANK FINANCING--WE MAY NOT HAVE THE ABILITY TO BORROW THE FUNDS NECESSARY TO
MEET CAPITAL REQUIREMENTS IN THE FUTURE.
    
 
Zemex has utilized, and Zemex Canada will continue to utilize, bank debt in
addition to cash flow from operations to support its growth and to finance its
capital expansion program. The ability to borrow under Zemex's current bank
facility depends upon meeting specified levels of cash flow from operations.
Accordingly, bank borrowings could be restricted at a time when Zemex's capital
needs are strained by reduced cash flows. Any significant reductions in the
availability of bank borrowings could have a material adverse effect on the
Company's prospects.
 
ADVERSE EFFECT OF GOVERNMENT ENVIRONMENTAL, HEALTH AND SAFETY REGULATION
 
Zemex Canada's extraction and processing activities are subject to comprehensive
U.S. federal, state and local, Canadian federal and provincial and other foreign
laws and regulations relating to the environment and health and safety. Zemex
has and Zemex Canada will continue to regularly monitor and review operations,
procedures and policies for compliance with these laws and regulations
including, but not limited to, solid and hazardous waste regulations, worker
health and safety regulations, worker and community right-to-know requirements,
and clean water and clean air permitting and compliance requirements specific to
the extraction and processing of industrial minerals and metal powders. Despite
compliance efforts, the risk of environmental and other damage is inherent in
the extraction and processing of industrial minerals and metal powders. Zemex
Canada cannot be certain that it will not incur material environmental
liabilities in the future. Moreover, the historical trend toward stricter
environmental regulation may continue. Future regulation may give rise to
additional compliance requirements and costs that could have a material adverse
effect on Zemex Canada. These events may include changes in, or modified
interpretations of, existing laws and regulations or enforcement policies. These
events may also include further investigation or evaluation of the potential
health hazards of certain industrial mineral and metal powder products,
intermediate products, by-products and wastes, and the environmental impact of
Zemex Canada operations.
 
EXTRACTION AND PROCESSING RISKS AND POTENTIAL INADEQUACY OF INSURANCE COVERAGE
 
The business of extraction and processing of industrial minerals and metal
powders is subject to many risks and hazards, including environmental hazards,
industrial accidents, periodic
 
                                      -7-
<PAGE>
interruptions due to inclement weather conditions, labor disputes, power
interruptions, critical equipment failures, fires, unusual or unexpected
geological or mining conditions and flooding. Such risks could result in damage
to, or destruction of, extraction or processing facilities, personal injury,
environmental damage, delays in extraction or production, monetary loss and
possible legal liability. Although Zemex Canada will maintain insurance within
ranges of coverage consistent with industry practice, it cannot be certain that
such insurance will be adequate to cover losses or continue to be available at
economically acceptable rates in the future. Zemex Canada may become subject to
liability for pollution, accidents or other hazards against which it is
uninsured.
 
ADVERSE EFFECT OF FLUCTUATIONS IN EXCHANGE RATES
 
   
Currency fluctuations may affect the revenue which Zemex Canada will realize
from its operations as its products are sold in the world market in United
States dollars. The costs of Zemex Canada will be incurred principally in
Canadian dollars and United States dollars. Fluctuations in the value of such
currencies could have an adverse effect on Zemex Canada. Zemex does not
currently engage in hedging activities and we do not anticipate that Zemex
Canada will engage in hedging activities.
    
 
RISK OF WORK STOPPAGE DUE TO STRIKE OR LOCKOUT
 
Approximately 35% of Zemex Canada's workforce is unionized and represented by
unions. The current contracts expire at different times between December 31,
1998 and February 28, 2002. If Zemex Canada does not renew the contracts on
their expiration, work stoppages due to strike or lockout may result.
 
                        REINCORPORATION MERGER PROPOSAL
 
BACKGROUND OF THE REINCORPORATION MERGER PROPOSAL
 
   
The board of directors of Zemex has determined that it is advisable to change
Zemex's domicile from Delaware to Canada. A principal reason for the change in
domicile is to take advantage of investment interest by, and legal investment
regulations affecting, Canadian pension and retirement funds. Currently,
Canadian legal investment regulations restrict the investment by Canadian
pension and retirement funds in Zemex common stock. Generally, Canadian pension
and retirement funds may only invest up to 20% of the cost of their assets in
foreign property. Foreign property does not include shares of a Canadian
corporation which maintains an office in Canada so long as the corporation, or
another corporation that is controlled by the corporation, employs more than
five individuals in Canada full time in its business activities. Zemex Canada
common shares meet this test and accordingly, do not constitute foreign property
so that Canadian pension and retirement funds would not be restricted in their
investments in Zemex Canada common shares by the 20% test. As a result, these
funds would have greater flexibility to invest in Zemex Canada common shares
than in Zemex common stock. Management believes that Canadian pension and
retirement plans have substantial interest in investment in natural resource and
specialty material companies and that the ability of such funds to invest in
Zemex Canada common shares would positively affect the market for these shares.
    
 
Over the past 18 months, Zemex has pursued several acquisition proposals, each
of which would, if consummated, have resulted in Zemex being, or being part of,
a Canadian corporation. For various reasons, none of the acquisition
transactions were consummated, and
 
                                      -8-
<PAGE>
the board is now proposing that the change of domicile be effected directly
pursuant to the merger agreement.
 
   
In the merger, each share of Zemex common stock will be changed into one common
share of Zemex Canada, and Zemex will become a wholly-owned subsidiary of Zemex
Canada. The change of domicile will not result in any material change to the
business of Zemex and will not have any effect on the relative equity or voting
interests of Zemex's shareholders in the Zemex business. The change in domicile
will, however, result in changes in the rights and obligations of current Zemex
shareholders under applicable corporate laws. For an explanation of these
differences, see "Comparative Rights of Shareholders." In addition, the merger
may have adverse tax consequences for shareholders. For example, some
shareholders may recognize taxable gain in the merger. For a more detailed
explanation of the circumstances to be considered in determining the tax
consequences, see "Material United States Federal Tax Consequences" and
"Material Canadian Federal Income Tax Consequences."
    
 
PURPOSES AND EFFECTS OF THE CHANGE OF DOMICILE
 
   
The purpose of the reincorporation merger is to change Zemex's domicile from
Delaware to Canada, which the Zemex board of directors believes will enable
shareholders to benefit from an active trading market in Canada for Canadian
natural resource companies. The expected dual listing of Zemex Canada common
shares for trading on the New York Stock Exchange and The Toronto Stock Exchange
should also enhance liquidity for shareholders through the creation of a broader
and deeper trading market.
    
 
RECOMMENDATION OF THE ZEMEX BOARD OF DIRECTORS
 
THE BOARD OF DIRECTORS OF ZEMEX HAS UNANIMOUSLY APPROVED THE PROPOSED
TRANSACTION AND RECOMMENDS THAT SHAREHOLDERS APPROVE THE MERGER AGREEMENT.
 
In reaching its decision, the board reviewed the fairness to Zemex and its
shareholders of the proposed transactions and considered, without assigning
relative weights to, the following factors:
 
    - The belief of the board of directors that the reincorporation merger
      should provide greater access to the Canadian capital markets and
      investors, which the board believes have a significant interest in mining
      and other natural resource issues;
 
    - The belief of the board of directors that liquidity for shareholders of
      Zemex Canada should be enhanced by the dual listing of Zemex Canada common
      shares for trading on The Toronto Stock Exchange and the New York Stock
      Exchange;
 
    - The belief that adverse tax consequences of the proposed transaction will
      be minimized due to the current low trading price of the Zemex common
      stock. For U.S. tax purposes, Zemex stockholders who are U.S. persons must
      recognize taxable gains, but not losses, on their Zemex stock;
 
    - The fact that Zemex's principal executive office is currently located in
      Canada, and that it has, through operations in Canada, established
      relationships with the investment and mining communities in Canada; and
 
    - The fact that the shareholders have an opportunity to vote on the
      reincorporation merger.
 
                                      -9-
<PAGE>
Without relying on any single factor listed above more than any other factor,
the Zemex board of directors, based upon its consideration of all such factors
taken as a whole, has concluded that the proposed transaction is fair to Zemex
and its shareholders. ACCORDINGLY, THE ZEMEX BOARD OF DIRECTORS UNANIMOUSLY
RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE REINCORPORATION MERGER.
 
                                MERGER AGREEMENT
 
The following summary of the terms of the merger agreement is qualified in its
entirety by reference to the full text of the merger agreement, attached as
Annex A to this proxy statement/prospectus.
 
   
OVERVIEW OF THE MERGER AGREEMENT
    
 
Under the terms of the merger agreement, Zemex Acquisition Corporation, a newly
formed subsidiary of Zemex Canada, will merge with and into Zemex. The separate
corporate existence of Zemex Acquisition will cease and Zemex will be the
surviving corporation. Each previously outstanding share of Zemex Acquisition
common stock will be converted into one share of Zemex common stock and each
previously outstanding share of Zemex common stock will be converted into one
Zemex Canada common share. The previously outstanding Zemex Canada common shares
will be canceled. As a result of the foregoing, upon consummation of the
reincorporation merger, Zemex will become a wholly-owned subsidiary of Zemex
Canada, and the current shareholders of Zemex will own all of the outstanding
Zemex Canada common shares. In the reincorporation merger, Zemex will change its
name to Zemex U.S. Corporation and immediately prior to the reincorporation
merger, Zemex Canada will change its name to Zemex Corporation. For accounting
purposes, the assets and liabilities of Zemex Canada and its subsidiaries on a
consolidated basis immediately after the consummation of the reincorporation
merger will be substantially identical to the assets and liabilities of Zemex
and its subsidiaries on a consolidated basis immediately prior to the
reincorporation merger.
 
EFFECTIVE TIME OF THE REINCORPORATION MERGER
 
The reincorporation merger will become effective upon:
 
    1.  The approval of the merger agreement by the shareholders of Zemex and
       Zemex Acquisition;
 
    2.  The delivery of a duly executed and verified certificate of merger to
       the Secretary of State of the State of Delaware; and
 
    3.  The satisfaction or waiver of the other conditions set forth below.
 
   
We anticipate that the certificate of merger will be filed shortly after the
special meeting of Zemex shareholders.
    
 
CONDITIONS TO THE CONSUMMATION OF THE REINCORPORATION MERGER
 
The obligation of each of the parties to the merger agreement to effect the
reincorporation merger is subject to the satisfaction of certain conditions at
or prior to the time the merger becomes effective, including:
 
    1.  The shareholders of Zemex and Zemex Acquisition shall have duly approved
       the transactions contemplated by the merger agreement;
 
                                      -10-
<PAGE>
   
    2.  No action, suit or proceeding shall be pending or threatened before any
       court, administrative agency or arbitrator in which an unfavorable ruling
       would:
    
 
            - prevent consummation of any of the transactions contemplated by
              the merger agreement;
 
            - cause any of the transactions contemplated by the merger agreement
              to be rescinded following consummation;
 
            - cause Zemex Canada or Zemex, or any of their officers or
              directors, to become liable for any material damages; or
 
   
            - affect adversely the right of Zemex Canada after the
              reincorporation merger to own the former assets or to operate the
              former businesses of Zemex;
    
 
   
    3.  There has not been any statute, rule or regulation enacted, promulgated
       or deemed applicable to the reincorporation merger by any governmental
       entity which prevents the consummation of the reincorporation merger;
    
 
   
    4.  There shall not have been a breach of any representation, warranty,
       covenant or agreement of Zemex, Zemex Canada, or Zemex Acquisition set
       forth in the merger agreement which, individually or in the aggregate,
       would have a material adverse effect on Zemex; and
    
 
   
    5.  Zemex Canada common shares shall have been listed for trading on the New
       York Stock Exchange and The Toronto Stock Exchange.
    
 
The merger agreement also provides that, subject to certain limitations, any
term or provision of the merger agreement may be waived by written agreement of
Zemex.
 
THIRD PARTY CONSENTS
 
The only material consents, approvals or authorizations of or filings with any
governmental entity required to consummate the reincorporation merger are the
approval of the shareholders of Zemex and Zemex Acquisition in accordance with
the laws of the State of Delaware and the filing with the Secretary of State of
the State of Delaware of the certificate of merger for the reincorporation
merger.
 
EXCHANGE OF SHARE CERTIFICATES
 
   
No exchange of certificates that, prior to the effective time of the merger,
represented shares of Zemex common stock is required with respect to the
reincorporation merger and the transactions contemplated by the merger
agreement. Promptly after the effective time of the merger,
                        shall mail to each record holder of certificates that
immediately prior to the effective time of the merger represented shares of
Zemex common stock a letter of transmittal and instructions for use in
surrendering certificates for shares of Zemex common stock. Upon the surrender
of each certificate formerly representing Zemex common stock, together with a
properly completed letter of transmittal, Montreal Trust shall issue in exchange
a common share certificate of Zemex Canada representing Zemex Canada common
shares and the Zemex common stock certificate shall be canceled. Until so
surrendered and exchanged, each Zemex common stock certificate shall represent
solely the right to receive Zemex Canada common shares.
    
 
                                      -11-
<PAGE>
EMPLOYEE MATTERS; STOCK OPTIONS
 
Following the reincorporation merger, Zemex will continue pension benefit plans
for Zemex employees, most of whom will continue to be employed by Zemex (and not
Zemex Canada) following the merger. The cost of such plans is expected to be
consistent with costs historically incurred by Zemex for employee benefits.
 
As of the effective time of the reincorporation merger, all options to purchase
shares of Zemex common stock granted or issued prior to the effective time of
the merger and all rights to purchase Zemex common stock arising under Zemex
stock purchase plans will entitle the holder to purchase an equal number of
Zemex Canada common shares. After the effective date of the merger, Zemex Canada
will adopt new option and stock purchase plans to replicate Zemex's existing
plans. Future options and rights would be subject to and governed by the terms
of the new option or purchase plan or plans and any related agreements.
 
INDEMNIFICATION
 
For six years after the reincorporation merger, Zemex Canada will indemnify any
current or former directors and officers of Zemex or any of Zemex's subsidiaries
against all losses and liabilities arising out of their service in such
capacities prior to and including the effective time of the reincorporation
merger. Zemex Canada has also included provisions in its bylaws for the
limitation of liability of directors and indemnification of directors and
officers to the fullest extent permitted by applicable law.
 
TERMINATION
 
The merger agreement may be terminated and the reincorporation merger may be
abandoned at any time, either before or after approval thereof by the
shareholders of Zemex by action of the board of directors of Zemex.
 
                          VOTING AND PROXY INFORMATION
                                SPECIAL MEETING
 
   
A special meeting of the Zemex shareholders will be held at 1:00 p.m. on
         , January   , 1999, at The Chase Manhattan Bank, Room "C," 11th Floor,
270 Park Avenue, New York, New York 10017 (or at any adjournments or
postponements thereof) to consider and vote on the proposal to approve the
merger agreement and any other matters that may properly come before such
meeting. The presence, in person or by proxy, of shareholders holding a majority
of the outstanding shares of Zemex common stock will constitute a quorum.
    
 
   
The vote of any Zemex shareholder who is represented at the special meeting by
proxy will be cast as specified in the proxy. If no vote is specified in a duly
executed and delivered proxy, such vote will be cast FOR the proposal. Any Zemex
shareholder of record who is present at the special meeting in person will be
entitled to vote at the meeting regardless of whether the shareholder has
previously granted a proxy for the special meeting.
    
 
THE BOARD OF DIRECTORS OF ZEMEX HAS APPROVED THE PROPOSED REINCORPORATION MERGER
AND RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE APPROVAL OF THE MERGER AGREEMENT.

                               PROXY SOLICITATION
 
The total cost of soliciting proxies will be borne by Zemex. Proxies may be
solicited by officers and regular employees of Zemex without extra remuneration
by personal interviews, telephone and by electronic means. Zemex anticipates
that bank, brokerage houses and other custodians, nominees and fiduciaries will
forward soliciting material to shareholders and those persons will be reimbursed
for the related out-of-pocket expenses they incur.
 
                                  RECORD DATE
 
   
Only those shareholders of record at the close of business on December 14, 1998,
as shown in Zemex's records, will be entitled to vote or to grant proxies to
vote at the special meeting.
    
 
                           VOTE REQUIRED FOR APPROVAL
 
   
Approval of the merger agreement requires the affirmative vote of the
shareholders of Zemex holding at least a majority of the outstanding shares of
Zemex common stock. Abstentions and broker "non-votes" will have the effect of
votes against the approval of the merger agreement. As of December 14, 1998,
there were 8,698,663 shares of Zemex common stock outstanding and entitled to
vote. The directors and executive officers of Zemex and their affiliates
directly owned, in the aggregate, 1,084,903 shares (approximately 12%) of the
total number of shares of Zemex common stock outstanding at the record date. In
addition, Dundee Bancorp International Inc. owns approximately 34% of the
outstanding shares of Zemex common stock. These persons have indicated that they
will vote all of their shares of Zemex common stock for the approval of the
merger agreement.
    
 
                                    PROXIES
 
GENERAL
 
   
Each Zemex shareholder as of December 14, 1998, will receive a proxy card.
    
 
    - A shareholder of Zemex may grant a proxy to vote for or against, or to
      abstain from voting on, the proposal to approve the merger agreement by
      marking his/her proxy card appropriately and executing it in the space
      provided.
 
    - Holders of Zemex common stock whose names appear on the stock records of
      Zemex should return their proxy card to Zemex's transfer agent, First
      Union National Bank, in the envelope provided with the proxy card.
 
    - Zemex shareholders who hold their Zemex common stock in the name of a
      bank, broker or other nominee should follow the instructions provided by
      their bank, broker or nominee on voting their shares.
 
   
TO BE EFFECTIVE, A PROXY CARD MUST BE RECEIVED PRIOR TO THE SPECIAL MEETING. ANY
PROPERLY EXECUTED PROXY WILL BE VOTED IN ACCORDANCE WITH THE SPECIFICATION
INDICATED ON THE PROXY CARD. A PROPERLY EXECUTED AND RETURNED PROXY CARD IN
WHICH NO SPECIFICATION IS MADE WILL BE VOTED FOR THE PROPOSAL TO APPROVE THE
MERGER AGREEMENT.
    
 
                                      -13-
<PAGE>
If any other matters are properly presented at the special meeting for
consideration, including consideration of a motion to adjourn the meeting to
another time and/or place (including adjournment for the purpose of soliciting
additional proxies), the persons named in the proxy card and acting under its
authority will have discretion to vote on such matters in accordance with their
best judgment.
 
REVOCATION
 
Holders of Zemex common stock whose names appear on the stock records of Zemex
may revoke their proxy card at any time prior to its exercise by:
 
    - giving written notice of such revocation to First Union National Bank;
 
    - appearing and voting in person at the special meeting; or
 
    - properly completing and executing a later-dated proxy and delivering it to
      First Union National Bank at or before the special meeting.
 
Presence without voting at the special meeting will not automatically revoke a
proxy, and any revocation during the meeting will not affect votes previously
taken.
 
Zemex shareholders who hold their Zemex common stock in the name of a bank,
broker or other nominee should follow the instructions provided by their bank,
broker or nominee in revoking their previously voted shares. See "Voting and
Proxy Information--Proxies."
 
VALIDITY
 
   
All questions as to the validity, form, eligibility (including time of receipt),
and acceptance of proxy cards will be determined by the Zemex board of
directors. Any such determination will be final and binding. The Zemex board of
directors will have the right to waive any irregularities or conditions as to
the manner of voting. Zemex may accept proxies by any reasonable form of
communication so long as Zemex can be reasonably assured that the communication
is authorized by the Zemex shareholder.
    
 
                               DISSENTERS' RIGHTS
 
Under Section 262 of the Delaware General Corporation Law, shareholders are
entitled to the payment of the fair value of their shares in certain corporate
transactions, such as a merger. However, under Section 262(b) such appraisal
rights are not available in a merger if:
 
    1.  The shares of the corporation were listed on a national securities
       exchange prior to the merger; and
 
    2.  The shareholders of the corporation receive in the merger shares of a
       corporation that are listed for trading on a national securities
       exchange.
 
Because the Zemex common stock was, and Zemex Canada common shares will be,
listed for trading on the New York Stock Exchange, Zemex shareholders will not
have appraisal rights in the reincorporation merger.

                MATERIAL UNITED STATES FEDERAL TAX CONSEQUENCES
    
 
The following is a summary of material United States tax consequences generally
applicable to United States holders of Zemex common stock or, after the
reincorporation merger, Zemex Canada common shares, who hold the Zemex common
stock or Zemex Canada common shares as capital assets and who do not own,
directly, indirectly or constructively, 10% or more of Zemex's outstanding
voting stock or Zemex Canada's outstanding voting shares. As used in this
summary, the term "U.S. holder" means a beneficial owner of Zemex common stock
or, after the reincorporation merger, Zemex Canada common shares, that is (1) a
citizen or resident of the United States; (2) a corporation organized under the
laws of the United States or any state; or (3) otherwise subject to United
States federal income taxation on a net income basis in respect of Zemex common
stock or, after the reincorporation merger, Zemex Canada common shares.
 
This summary does not address material income tax considerations of special
concern to insurance companies, broker-dealers, investors liable for alternative
minimum tax, investors that hold Zemex common stock, or, after the
reincorporation merger, Zemex Canada common shares, as part of a straddle or a
hedging or conversion transaction, or investors whose functional currency is not
the U.S. dollar.
 
   
This summary is based on the Internal Revenue Code of 1986, as amended, judicial
decisions, administrative pronouncements, and existing and proposed U.S.
Treasury Department regulations, changes to any of which after the date of this
proxy statement/prospectus could apply on a retroactive basis and affect the tax
consequences described herein. If you are a U.S. holder, you should consult your
own tax advisor with respect to tax consequences that may arise out of your own
particular circumstances.
    
 
                      TAX CONSEQUENCES OF REINCORPORATION
 
CONSEQUENCES FOR U.S. HOLDERS
 
   
As used herein, the term "U.S. holder" means (1) a citizen or resident of the
United States; (2) a corporation or partnership created or organized under the
laws of the United States or any State thereof (including the District of
Columbia), including any organization treated as a U.S. partnership under any
applicable Treasury Regulation; (3) an estate or trust described in Section
7701(a)(30) of the Internal Revenue Code; or (4) a person otherwise subject to
U.S. Federal income taxation on its worldwide income. A U.S. HOLDER WILL
RECOGNIZE GAIN WITH RESPECT TO THEIR ZEMEX COMMON STOCK ON THE REINCORPORATION
MERGER IN AN AMOUNT EQUAL TO THE EXCESS, IF ANY, OF THE FAIR MARKET VALUE OF THE
ZEMEX COMMON STOCK OVER THE U.S. HOLDER'S BASIS IN THE ZEMEX COMMON STOCK. A
U.S. HOLDER WILL NOT RECOGNIZE LOSS, IF ANY, WITH RESPECT TO THE U.S. HOLDER'S
ZEMEX COMMON STOCK AS A RESULT OF THE REINCORPORATION MERGER. In addition, if
the U.S. holder holds some Zemex common stock at a gain and other Zemex common
stock at a loss, the U.S. holder will, as a result of the reincorporation
merger, recognize the gains but not losses inherent in the Zemex common stock.
Any gain recognized by a U.S. holder on Zemex common stock in the
reincorporation merger will be capital gain if the U.S. holder has held such
common stock as a capital asset, and will be long term capital gain if the U.S.
holder has held such common stock for more than one year before the consummation
of the reincorporation merger.
    
 
                                      -15-
<PAGE>
   
A U.S. holder's basis in Zemex Canada common shares received in the
reincorporation merger will equal the sum of: (1) the U.S. holder's basis in the
Zemex common stock and (2) the amount of any gain recognized by the U.S. holder
in the reincorporation merger. A U.S. holder's holding period in Zemex Canada
common shares should include the U.S. holder's holding period in the Zemex
common stock transferred upon the merger, even if the U.S. holder recognized a
gain on the Zemex common stock prior to transfer.
    
 
A U.S. holder will be required to report the reincorporation merger to the
Internal Revenue Service on Form 926 (and may be subject to penalties for
failure to file such form) if:
 
    - The U.S. holder fails to timely report any gain from the transaction on
      the U.S. holder's income tax return for the year of the transaction; or
 
    - In certain circumstances, if the U.S. holder owns, directly or by
      attribution, 5% or more, by vote or value, of the common shares of Zemex
      Canada immediately after the reincorporation merger.
 
   
Under Treas. Reg. Section 1.351-3(a), which applies to persons who receive stock
in a transfer to a controlled corporation, a U.S. holder must file with its
income tax return for the year of the merger a statement describing:
    
 
   
    - The stock of Zemex transferred to Zemex Canada, and the cost basis of this
      stock; and
    
 
   
    - The stock of Zemex Canada received, including the number and fair market
      value of these shares.
    
 
Under the "wash sale" rules, a taxpayer who sells stock at a loss generally may
not claim the loss if the taxpayer acquired "substantially identical" securities
within the 61-day period beginning 30 days before, and ending 30 days after, the
loss sale. Under these rules, there may be some risk that a U.S. holder who
recognizes gain on his Zemex common stock in the reincorporation merger would be
prevented from claiming a loss on the sale either of Zemex common stock or Zemex
Canada common shares during the period beginning 30 days before and ending 30
days after the reincorporation merger.
 
CONSEQUENCES FOR FOREIGN HOLDERS
 
Except as discussed below, a "foreign holder," or a holder of Zemex common stock
who is not a U.S. holder, should not recognize gain or loss for U.S. income tax
purposes as a result of the merger.
 
A foreign holder who has owned, directly or constructively, more than 5% of the
outstanding Zemex common stock at any time during the five years preceding the
reincorporation merger (or, if shorter, the foreign holder's holding period in
the Zemex common stock) would recognize taxable gain or loss with respect to the
Zemex common stock if the Zemex common stock is a "U.S. real property interest"
as defined in Section 897(c) of the Internal Revenue Code. In general, a 5%
foreign holder's Zemex common stock would be a U.S. real property interest if
50% or more of the fair market value of Zemex's trade or business and real
property assets have consisted of interests in U.S. real property at any time
during the preceding five years (or, if shorter, the 5% foreign holder's holding
period in the Zemex common stock). Zemex believes that Zemex common stock does
not constitute a U.S. real property interest as to its 5% foreign holders.
Accordingly, Zemex does not believe that 5% foreign holders will recognize
taxable gain or loss on their Zemex common stock as a result of the
reincorporation merger.
 
                                      -16-
<PAGE>
In accordance with Treasury Regulations, at the request of a 5% foreign holder,
Zemex will inform the 5% foreign holder whether, in Zemex's determination, the
5% foreign holder's interest in Zemex has been a U.S. real property interest
during the applicable period, and will provide notice of such determination to
the Internal Revenue Service within a reasonable time of receiving such a
request. The request of a 5% foreign holder for such a determination should be
accompanied by the name, address and U.S. taxpayer identification number (if
any) of the 5% foreign holder.
 
   
CONSEQUENCES FOR ZEMEX AND ZEMEX CANADA
    
 
   
It is not anticipated that Zemex or Zemex Canada will be subject to adverse U.S.
income tax consequences as a result of the reincorporation merger. If,
subsequent to the reincorporation merger, Zemex Canada receives dividend or
interest payments from Zemex, such payments will be subject to U.S. withholding
tax at a rate of 5% or 10%, respectively.
    
 
   
          TAX CONSEQUENCES OF OWNERSHIP OF ZEMEX CANADA COMMON SHARES
    
 
   
Distributions made by Zemex Canada with respect to Zemex Canada common shares
(which for these purposes will include the amount of any Canadian taxes withheld
therefrom) will generally be includible in the gross income of a U.S. holder as
foreign source dividend income to the extent that such distributions are paid
out of Zemex Canada's current or accumulated earnings and profits as determined
under U.S. federal income tax principles. To the extent, if any, that the amount
of any such distribution exceeds Zemex Canada's current and accumulated earnings
and profits as so computed, it will first reduce the U.S. holder's tax basis in
its Zemex Canada common shares to the extent thereof, and to the extent in
excess of such tax basis, will be treated as gain from the sale or exchange of
property. The amount of any cash distribution paid in Canadian dollars will be
equal to the U.S. dollar value of the Canadian dollars determined at the spot
Canadian dollar/U.S. dollar rate on the date of receipt, regardless of whether
the payment is in fact converted into U.S. dollars at that time. Gain or loss,
if any, realized on the sale or disposition of Canadian dollars will generally
be U.S. source ordinary income or loss for a U.S. holder. U.S. holders will not
be entitled to claim a dividends received deduction with respect to
distributions by Zemex Canada (unless the U.S. holder is a corporation which
owns by vote and value at least 10% of the stock of Zemex Canada, in which case
a portion of such distributions may be eligible for such deduction).
    
 
   
Future distributions of Zemex Canada common shares or other interests in Zemex
Canada, or of rights to subscribe for Zemex Canada common shares, may be treated
as distributions subject to U.S. federal income tax.
    
 
   
Subject to certain limitations, Canadian taxes withheld from or paid on dividend
distributions generally will be eligible for credit against the U.S. holder's
U.S. federal income taxes. The limitation on foreign taxes eligible for credit
is calculated separately with respect to specific classes of income.
    
 
   
A U.S. holder will generally recognize a capital gain or loss for U.S. federal
income tax purposes on the sale or disposition of Zemex Canada common shares in
the same manner as on the sale or disposition of any other shares held as
capital assets and such capital gain or loss will be long-term capital gain or
loss if the U.S. holder's holding period for such Zemex
    
 
                                      -17-
<PAGE>
   
Canada common shares exceeds one year on the date of sale or disposition. Gain,
if any, will generally be U.S. source gain.
    
 
   
Under certain limited circumstances, foreign holders of Zemex Canada common
shares will be subject to U.S. federal income taxation at graduated rates upon
dividends or gain with respect to their Zemex Canada common shares, if such
income or gain is treated as effectively connected with the conduct of the
recipient's trade or business within the United States.
    
 
   
Zemex Canada believes that, following the reincorporation merger, it will not be
a "passive foreign investment company," a "foreign personal holding company" or
a "controlled foreign corporation" for U.S. Federal income tax purposes. If
Zemex Canada were one of these three types of companies following the
reincorporation merger, some or all U.S. holders of Zemex Canada common shares
would be required to include in their taxable income certain undistributed
amounts of Zemex Canada's income or, in certain circumstances, to pay an
interest charge together with tax calculated at maximum rates on certain "excess
distributions," defined as including gain on the sale of stock.
    
 
   
Any U.S. holder who owns 10% or more in value of the stock of Zemex Canada be
may required to file IRS Form 5471 with respect to Zemex Canada.
    
 
   
In general, information reporting requirements may apply to dividend payments
(or other taxable distributions) for Zemex Canada common shares made within the
United States to a non-corporate United States person, and "backup withholding"
at the rate of 31% may apply to such payments if the holder or beneficial owner
fails to provide an accurate taxpayer identification number in the manner
required by United States law and applicable regulations, if there has been
notification from the Internal Revenue Service of a failure by the holder or
beneficial owner to report all interest or dividends required to be shown on its
federal income tax returns or, in certain circumstances, if the holder or
beneficial owner fails to comply with applicable certification requirements.
Certain corporations and persons that are not United States persons may be
required to establish their exemption from information reporting and backup
withholding by certifying their status on Internal Revenue Service Forms W-8 or
W-9.
    
 
   
Amounts withheld under the backup withholding rules may be credited against a
holder's tax liability, and a holder may obtain a refund of any excess amounts
withheld under the backup withholding rules by filing the appropriate claim for
refund with the United States Internal Revenue Service.
    
 
   
               MATERIAL CANADIAN FEDERAL INCOME TAX CONSEQUENCES
    
 
   
The following is a summary of the material Canadian federal income tax
consequences under the Income Tax Act (Canada) generally applicable to
shareholders of Zemex common stock who dispose of their shares pursuant to the
merger agreement, who for purposes of the Income Tax Act hold their Zemex common
stock as capital property, deal at arm's length with Zemex and Zemex Canada and
are not affiliated with Zemex or Zemex Canada. This summary does not apply to a
holder that is a "financial institution" within the meaning of subsection
142.2(1) of the Income Tax Act as such definition is proposed to be amended by
the Federal Budget dated February 24, 1998, nor does this summary apply to any
holder in respect of whom Zemex or Zemex Acquisition Corporation is a foreign
affiliate for purposes of the Income Tax Act nor to any holder in respect of
whom any such shares constitute an "offshore investment fund property" for
purposes of the Income Tax Act. This summary is
    
 
                                      -18-
<PAGE>
   
based on the assumption that all issued Zemex Canada common shares are at all
times listed on The Toronto Stock Exchange or another prescribed stock exchange.
    
 
   
The summary is based on the current provisions of the Income Tax Act, the
regulations thereunder, jointly referred to as the tax regulations, the current
provisions of the Canada-United States Income Tax Convention, 1980, referred to
as the Tax Treaty and an understanding of the current publicly available
statements of the administrative practices of Revenue Canada, Customs, Excise
and Taxation. This summary takes into account specific proposals to amend the
Income Tax Act and tax regulations publicly announced by the Minister of Finance
(Canada) prior to the date hereof, but there is not certainty that such
proposals will be enacted in the form proposed or at all. This summary does not
otherwise take into account tax legislation or considerations of any province,
territory or foreign jurisdiction.
    
 
   
YOU SHOULD CONSULT YOUR OWN TAX ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES
THAT MAY ARISE OUT OF YOUR PARTICULAR CIRCUMSTANCES.
    
 
   
CONSEQUENCES FOR RESIDENTS OF CANADA
    
 
   
The following portion of the summary is applicable only to holders who are
resident or are deemed to be resident in Canada for purposes of the Income Tax
Act.
    
 
   
Holders of Zemex common stock who exchange their shares pursuant to the merger
agreement Zemex Canada common shares will be considered to have disposed of
their Zemex common stock for proceeds of disposition equal to the fair market
value of Zemex Canada common shares received in exchange. The aggregate adjusted
cost base of Zemex Canada common shares immediately after the exchange will be
equal to their fair market value at that time. Holders who exchange their Zemex
common stock and holders who dispose of Zemex Canada common shares in the future
will be considered to have realized a capital gain (or capital loss) to the
extent the proceeds of disposition exceed (or are less than) the aggregate of
the adjusted cost base of the Zemex common stock or Zemex Canada common shares
immediately before the exchange or disposition and any reasonable costs of
disposition.
    
 
   
Three-quarters of any capital gain realized on an exchange of Zemex common stock
or on a future disposition of Zemex Canada common shares will be included in
income as a taxable capital gain and three-quarters of any capital loss
sustained under these circumstances may be deducted against other taxable
capital gains in accordance with the detailed rules in the Income Tax Act in
that regard. Taxable capital gains of a Canadian-controlled private corporation
may be subject to an additional 6 2/3% refundable tax, which may be refundable
in the circumstances and to the extent specified in the Income Tax Act.
    
 
   
CONSEQUENCES FOR NON-RESIDENTS OF CANADA
    
 
The following portion of the summary is applicable only to holders who are
neither resident nor deemed to be resident in Canada for purposes of the Income
Tax Act and who do not use or hold, and are not deemed to use or hold, their
Zemex common stock or Zemex Canada common shares in connection with carrying on
business in Canada.
 
No tax will be payable under the Income Tax Act on any capital gain realized by
a non-resident holder on the disposition of Zemex common stock in exchange for
Zemex Canada common shares pursuant to the merger agreement.
 
                                      -19-
<PAGE>
No tax will be payable under the Income Tax Act on any capital gain realized by
non-resident holders on a future disposition of Zemex Canada common shares
unless Zemex Canada common shares constitute taxable Canadian property at that
time. Zemex Canada common shares of non-resident holders will not constitute
"taxable Canadian property" unless at any time during the period of five years
immediately preceding the date such shares are disposed of, 25% or more of the
issued shares (and in the view of Revenue Canada, taking into account certain
interests in or rights to acquire shares) of any class or series of the capital
stock of Zemex Canada were owned by the non-resident holder, by persons with
whom the non-resident holder did not deal at arm's length, or by any combination
thereof. Even if Zemex Canada common shares are taxable Canadian property, a
gain realized on such disposition may be exempt from tax under the provisions of
an applicable income tax treaty. For example, the Tax Treaty will generally
exempt from Canadian tax a gain realized on such disposition by a holder who is
resident in the United States for purposes of the Tax Treaty provided the value
of Zemex Canada common shares is not at that time derived principally from real
property situated in Canada.
 
Dividends paid or credited to a non-resident holder of Zemex Canada common
shares will be subject to non-resident withholding tax under the Income Tax Act
at 25%, although such rate may be reduced under the provisions of an applicable
income tax treaty. For example, under the Tax Treaty, the rate is generally
reduced to 15% in respect of dividends paid to a person who is the beneficial
owner and who is resident in the United States for purposes of the Tax Treaty
(and who owns less than 10% of Zemex Canada's voting stock). Under the Tax
Treaty, dividends paid to certain religious, scientific, charitable and other
tax exempt organizations and certain pension organizations that are resident in,
and exempt from tax in, the United States are exempt from Canadian withholding
tax. Provided that certain administrative procedures are observed by the holder,
Zemex Canada will not be required to withhold tax on dividend payments to such
organizations.
 
   
                       COMPARATIVE RIGHTS OF SHAREHOLDERS
    
 
   
When the reincorporation merger is effective, the shareholders of Zemex, a
Delaware corporation, will become shareholders of Zemex Canada, a Canadian
corporation organized under the Canada Business Corporations Act, or the CBCA.
Differences between the CBCA and the Delaware General Corporate Law, or DGCL,
will result in various changes in the rights of shareholders of Zemex.
    
 
   
The following is a summary of the rights of Zemex shareholders compared to those
of Zemex Canada shareholders under applicable law and charter documents. This
summary does not purport to be complete and is qualified in its entirety by
reference to Zemex Canada's Articles of Continuance and Bylaw No. 1, which are
attached to the registration statement of which this proxy statement/prospectus
is a part.

             REQUIREMENTS FOR EXTRAORDINARY CORPORATE TRANSACTIONS
    
 
   
MERGERS AND CONSOLIDATIONS
    
 
   
Under the DGCL, a merger or consolidation requires the approval of a majority of
each corporation's shareholders entitled to vote on the matter except:
    
 
   
    - For a corporation which survives the merger where
    
 
   
     (1) The merger requires the issuance of common stock not exceeding 20% of
          such corporation's shares outstanding immediately prior to the merger;
    
 
                                      -26-
<PAGE>
   
     (2) The merger agreement does not amend the survivor's certificate of
          incorporation;
    
 
   
     (3) Each share of the corporation's stock outstanding immediately prior to
          the merger is to be an identical outstanding or treasury share of the
          surviving corporation after the merger; and
    
 
   
     (4) Shareholder approval is not specifically mandated in the survivor's
          certificate of incorporation;
    
 
   
    - For both corporations where the corporation surviving the merger owned at
      least a 90% of the stock of the other corporation prior to the merger; or
    
 
   
    - Where a corporation merges with or into a wholly-owned subsidiary and
      certain conditions are met.
    
 
   
The DGCL provides that unless a greater percentage is required by the charter,
the approval of a merger, consolidation, dissolution or sale of substantially
all of a corporation's assets requires the affirmative vote of the holders of a
majority of the shares entitled to vote.
    
 
   
Under the CBCA, certain extraordinary corporate actions are required to be
approved by special resolution of the holders of all shares, whether or not the
shares are designated as voting shares. Those extraordinary corporate actions
include certain amalgamations, continuances, sales, leases or exchanges of all
or substantially all the assets of a corporation other than in the ordinary
course of business, and other extraordinary corporate actions such as
liquidations, dissolutions or court ordered arrangements. A special resolution
is a resolution passed by at least two-thirds of the votes cast by the
shareholders who voted on the resolution. In certain cases, the special
resolution is also required to be approved by shareholders separately as a class
or series.
    
 
   
TAKEOVER AND ISSUER BIDS
    
 
   
Under the CBCA, a takeover bid for a corporation means, with certain statutory
exemptions, an offer:
    
 
   
    - Made to shareholders of the corporation at approximately the same time;
    
 
   
    - To acquire shares that, if combined with shares already beneficially owned
      or controlled, directly or indirectly, by the offeror or affiliates or
      associates of the offeror on the date of the takeover bid, would exceed
      10% of any class of issued shares of the corporation; and
    
 
   
    - Includes every offer, subject to certain statutory exceptions, by the
      corporation to repurchase its own shares (which is generally termed an
      issuer bid under provincial securities legislation).
    
 
   
Takeover bids (with a 20% threshold instead of a 10% threshold) and issuer bids
are also defined and regulated under provincial securities legislation. There
are differences in such definitions and in the rules applicable to such bids
from those contained in the CBCA. Takeover bids or issuer bids are, however,
subject to the applicable provisions of both the CBCA and relevant provincial
securities legislation.
    
 
   
As a general matter, any takeover bid or issuer bid must be made to all holders
resident in Canada of securities of the class that is subject to the bid. The
holders must be offered identical consideration and the bid must otherwise be
made in compliance with applicable provisions of the CBCA and provincial
securities legislation governing bids, subject to limited statutory exemptions.
In particular, the CBCA excludes from the CBCA definition of a takeover bid an
exempt offer, which includes an offer to fewer than 15 shareholders to purchase
    
 
                                      -27-
<PAGE>
   
shares by way of separate agreements. The scope of the exemption is limited,
however, by the analogous statutory exemptions in the securities legislation of
certain provinces. For example, the Securities Act (Ontario) provides for a
statutory exemption for a takeover bid (but not an issuer bid) where purchases
are made from not more than five persons or companies in the aggregate, the bid
is not made generally to securityholders of the subject class of securities and
the value of the consideration paid for any of the securities, including
brokerage fees or commissions, does not exceed 115% of the market price of the
securities of that class at the date of the bid determined in accordance with
the applicable legislation.
    
 
   
POST-BID ACQUISITIONS
    
 
   
In addition, provincial securities legislation of certain provinces, including
Ontario, provides for integration of a subsequent take-over bid that is a formal
bid or an issuer bid with prior pre-bid private transactions and restrictions on
post-bid acquisitions. Under the Securities Act (Ontario), a post-bid
acquisition arises when:
    
 
   
    - An offeror makes a takeover bid that is a formal bid or an issuer bid; and
    
 
   
    - Within the period of 90 days immediately preceding the bid, the offeror
      acquired beneficial ownership of securities of the class pursuant to a
      transaction not generally available to holders of that class of
      securities,
    
 
   
For post-bid acquisitions, the offeror must:
    
 
   
    - Offer consideration at least equal to the highest consideration paid per
      security in the prior transactions (or at least the cash equivalent of
      such consideration); and
    
 
   
    - Offer to acquire a number of securities from the seller that would be the
      same percentage of the total number of securities of that class
      beneficially owned by the seller at the time of the prior transaction.
    
 
   
An offeror is also prohibited from acquiring beneficial ownership of securities
of the class by way of a transaction that is not generally available on
identical terms to the holders of that class of securities for a 20 day period
following the expiration of the bid, whether or not any securities are taken up
under the bid.
    
 
   
Ontario Securities Commission Policy No. 9.1 provides for additional
requirements in connection with insider bids, issuer bids, going-private
transactions and related party transactions.
    
 
   
INSIDER BIDS
    
 
   
An insider bid means a takeover bid (as defined in the Securities Act (Ontario))
made:
    
 
   
    - By an insider of the offeree issuer;
    
 
   
    - By any associate or affiliate of an insider of an offeree issuer;
    
 
   
    - By any associate or affiliate of the offeree issuer; or
    
 
   
    - By an offeror acting jointly or in concert with any of the foregoing.
    
 
   
An insider bid does not include an issuer bid. With respect to insider bids and
issuer bids, Policy 9.1 requires enhanced disclosure in the offering document
and, subject to a limited exemption, that a formal valuation of the securities
of the offeree issuer that are the subject of the bid be prepared and summarized
in the offering document.
    
 
   
GOING-PRIVATE TRANSACTIONS
    
 
   
A going-private transaction means any acquisition or other transaction involving
an issuer where the shareholders' interest may be terminated without their
consent and without substituting an interest of equivalent value in a
participating security of the issuer, a successor to
    
 
                                      -28-
<PAGE>
   
the business of the issuer or a successor to the business of another entity that
controls the issuer. A going-private transaction does not include the
acquisition of participating securities pursuant to a statutory right of
acquisition.
    
 
   
With respect to going-private transactions, Policy 9.1 requires:
    
 
   
    - Enhanced disclosure in the proxy material sent to securityholders in
      connection with the transactions;
    
 
   
    - The preparation of a formal valuation of any securities of the issuer in
      which the interest of the holders will be terminated and any non-cash
      consideration will be offered for the securities;
    
 
   
    - The inclusion of a summary in the proxy material; and
    
 
   
    - That the minority shareholders of the issuer separately approve the
      transaction (depending on the circumstances, the required level of
      approval may be a simple majority or two-thirds of the votes cast by the
      minority shareholders).
    
 
   
INTERESTED SHAREHOLDER TRANSACTIONS
    
 
   
The DGCL prohibits a "business combination" between the corporation and an
"interested shareholder" within three years of the shareholder becoming an
"interested shareholder." An "interested shareholder" is any person (other than
the corporation or a majority owned subsidiary) who, directly or indirectly,
controls 15% or more of the outstanding voting stock. A "business combination"
includes a merger, consolidation, sale or other disposition of assets having an
aggregate value in excess of 10% of the consolidated assets of the corporation,
and certain transactions that would increase the interested shareholder's
proportionate share ownership in the corporation. This provision does not apply
where:
    
 
   
    - The business combination or the transaction that caused the shareholder to
      become an "interested shareholder" is approved by the corporation's board
      of directors prior to the time the interested shareholder acquired its
      shares;
    
 
   
    - Upon completion of the transaction in which the shareholder became an
      "interested shareholder," such shareholder held at least 85% of the
      outstanding voting stock of the corporation (excluding from the number of
      shares outstanding shares held by persons who are directors and also
      officers or by employee stock plans in which participants do not have the
      right to determine confidentially whether shares held subject to the plan
      will be tendered);
    
 
   
    - The business combination is approved by a majority of the board of
      directors and the affirmative vote of two-thirds of the votes entitled to
      be cast by disinterested shareholders at an annual or special meeting;
    
 
   
    - The corporation does not have a class of voting stock that is listed on a
      national securities exchange, authorized for quotation on the NASDAQ Stock
      Market, or held by more than 2,000 shareholders unless any of the
      foregoing results from action taken, directly or indirectly, by an
      interested shareholder; or
    
 
   
    - The corporation has opted out of this provision.
    
 
   
The CBCA does not contain a comparable provision with respect to business
combinations. However, policies of certain Canadian securities regulatory
authorities, including Policy 9.1, contain requirements in connection with
related party transactions. A related party transaction means, generally, any
transaction by which an issuer, directly or indirectly, acquires or transfers an
asset, acquires or issues treasury securities or assumes or transfers a
liability from or
    
 
                                      -29-
<PAGE>
   
to a related party by any means. "Related party" is defined in Policy 9.1 and
includes directors, senior officers and holders of at least 10% of the voting
securities of the issuer. Policy 9.1 requires more detailed disclosure in the
proxy material sent to security holders in connection with a related party
transaction, and, subject to certain exemptions, the preparation of a formal
valuation of the subject matter of the related party transaction and any non-
cash consideration offered and the inclusion of a summary of the valuation in
the proxy material. Policy 9.1 also requires, subject to certain exemptions,
that the minority shareholders of the issuer separately approve the transaction,
by either a simple majority or two-thirds of the votes cast, depending on the
circumstances.
    
 
   
CHANGES IN CONTROL
    
 
   
The business combination provisions of the DGCL described above may have had the
effect of deterring merger proposals, tender offers or other attempts to effect
changes in control of Zemex that were not negotiated with and approved by the
board of directors.
    
 
   
As noted above under "Votes Required for Extraordinary Corporate Transactions,"
takeover bids in Canada are regulated by corporate and securities legislation.
However, shareholder-ratified shareholders rights plans also exist in Canada to
further protect shareholders' rights by giving shareholders adequate time to
assess a takeover bid without undue pressure and to allow competing bids to
emerge.
    
 
   
                              ACCOUNTING TREATMENT
    
 
   
The indirect acquisition by Zemex Canada of the assets and liabilities of Zemex
in connection with the reincorporation merger will be accounted for as a
statutory reincorporation. There will not be any "step-up" or write-up of assets
for accounting purposes as a result of the reincorporation merger.
    
 
   
Pro forma financial information in contemplation of the reincorporation merger
has not been included in this proxy statement/prospectus because the statutory
reincorporation will largely result in a change in legal form only. The carrying
values of the assets and liabilities of Zemex Canada after the transaction will
substantially reflect the carrying values of the assets and liabilities of Zemex
prior to the transaction.
    
 
   
                               BUSINESS OF ZEMEX
    
 
   
Zemex was incorporated in 1985 as the successor to Pacific Tin Corporation.
Zemex is a niche producer of industrial minerals and metal products. Its
principal businesses are industrial minerals, metal powders, and aluminum waste
recycling. Its major products include feldspar, feldspathic minerals, kaolin,
sand, mica, talc, ferrous and non ferrous powders, and aluminum dross
derivatives.
    
 
   
                            BUSINESS OF ZEMEX CANADA
    
 
   
Zemex Canada was incorporated in December 1997 under the Canada Business
Corporations Act. It has not carried on an active business. Zemex Canada has
been organized to facilitate the change of domicile of Zemex from Delaware to
Canada. All of the outstanding common shares of Zemex Canada are currently owned
by Zemex. After consummation of the reincorporation merger Zemex shareholders
will own the common shares of Zemex Canada,
    
 
                                      -30-
<PAGE>
   
in the same relative proportions as their ownership of Zemex prior to the
merger, and Zemex will become a wholly-owned subsidiary of Zemex Canada and
Zemex Canada will continue to conduct the operations in which Zemex is now
engaged.
    
 
   
                            SELECTED FINANCIAL DATA
    
 
   
THE FOLLOWING SELECTED FINANCIAL INFORMATION FOR THE YEARS 1993 THROUGH 1997
INCLUDES BALANCE SHEET AND STATEMENT OF OPERATIONS DATA FROM THE AUDITED
CONSOLIDATED FINANCIAL STATEMENTS OF ZEMEX. THE FOLLOWING SELECTED FINANCIAL
INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1998 AND 1997 INCLUDES
BALANCE SHEET AND STATEMENT OF OPERATIONS DATA FROM UNAUDITED HISTORICAL
CONSOLIDATED FINANCIAL STATEMENTS OF ZEMEX. IN THE OPINION OF MANAGEMENT, THE
UNAUDITED FINANCIAL STATEMENTS REFLECT ALL ADJUSTMENTS (CONSISTING OF NORMAL
RECURRING ADJUSTMENTS) NECESSARY FOR A FAIR STATEMENT OF RESULTS FOR THE
UNAUDITED INTERIM PERIODS. THE INFORMATION CONTAINED IN THIS TABLE SHOULD BE
READ IN CONJUNCTION WITH "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS" AND THE CONSOLIDATED FINANCIAL STATEMENTS
AND ACCOMPANYING NOTES INCLUDED IN THE 1997 FORM 10-K, THE 1997 FORM 10-K/A-1,
THE MARCH 31, 1998 FORM 10-Q, THE JUNE 30, 1998 FORM 10-Q AND THE SEPTEMBER 30,
1998 FORM 10-Q THAT ARE INCORPORATED BY REFERENCE.
    
 
   
The financial statements of Zemex have been prepared in accordance with
accounting principles generally accepted in the United States. The application
of Canadian generally accepted accounting principles, which will be applicable
to Zemex Canada's financial statements, would not result in any material
differences in the Zemex financial statements.

RESTRICTIONS ON FREE TRANSFER OF ZEMEX CANADA COMMON SHARES IN CANADA
    
 
   
Zemex Canada common shares to be issued to shareholders resident in certain
provinces of Canada will be subject to restrictions imposed by law that may
limit the ability of a shareholder to resell the securities within the province
in which it resides. As an example, shareholders resident in the Province of
Ontario will only be able to resell their Zemex Canada common shares in Ontario
without having to rely on regulatory exemptions or discretionary relief after
Zemex Canada has been listed on the Toronto Stock Exchange for over one year.
Such shareholders should consult their legal advisors for a further description
of such possible restrictions. Additionally, any person, company or combination
of persons or companies holding a sufficient number of Zemex Canada common
shares to affect materially the control of Zemex Canada will be restricted in
selling Zemex Canada common shares pursuant to securities laws applicable in
Canada.
    
 
   
DIVIDEND POLICY
    
 
   
The declaration and payment of dividends by Zemex Canada will be subject to the
discretion of its Board of Directors. The amount of any such dividend and the
Board's policy with respect to the payment of dividends will depend on Zemex
Canada's results of operations, financial condition, capital requirements,
contractual restrictions and other factors deemed relevant by Zemex Canada's
board of directors.

All of the outstanding capital stock of Zemex Canada is currently owned by
Zemex. At the effective time of the reincorporation merger, each share of Zemex
common stock outstanding immediately prior to the consummation of the
reincorporation merger will be automatically converted into one Zemex Canada
common share and the existing Zemex Canada common shares will be canceled.
Accordingly, upon consummation of the reincorporation merger, the share
ownership of Zemex Canada will be identical to the stock ownership of Zemex
immediately prior to the reincorporation merger. In addition, outstanding
options to purchase shares of Zemex common stock will upon exercise entitle the
holder to purchase an equal number of Zemex Canada common shares.

    share). Zemex loaned Mr. Lister the full amount of the purchase price. This
    non-interest bearing loan, which was originally scheduled to mature in 1997,
    has been extended for two years by approval of the Board. The loan is
    evidenced by a promissory note secured by a pledge of the shares of Zemex
    common stock. If Mr. Lister leaves the employ of Zemex at any time prior to
    full payment of the loan, the principal amount will be due in full 30 days
    after the date his employment terminates. Any balance remaining unpaid on
    the loan after it is due will bear interest at the prime rate plus 1.0%. So

    shares of Zemex common stock in a manner consistent with the recommendation
    of the Board.

    of Zemex common stock acquired are held by Zemex as security for the loan
    guarantee.

           CAUTIONARY STATEMENT CONCERNING FORWARD LOOKING STATEMENTS
 
With the exception of historical matters, the matters discussed or incorporated

that involve risks and uncertainties that could cause actual results to differ

investment in Zemex Canada to Canadian and other investors, market acceptance in
the Canadian capital markets and enhanced liquidity. Factors that could cause
actual results to differ materially include:
 
    - fluctuations in aluminum prices;
 
    - problems regarding unanticipated competition;
 
    - processing, access and transportation of supplies;
 
    - availability of materials and equipment;
 
   
    - the occurrence of an unexpected or unavoidable event (a force majeure
      event), which may, for example, prevent Zemex Canada or a party
      contracting with it from achieving its objectives;
    
 
    - the failure of plant equipment or processes to operate in accordance with
      specifications or expectations;
 
    - accidents, labor relations or delays in start-up dates;
 
    - environmental costs and risks;
 
    - the outcome of acquisition negotiations and general domestic and
      international economic and political conditions; and
 
    - other factors described in this proxy statement/prospectus or Zemex
      filings with the SEC.
 
Many of these factors are beyond the ability of Zemex to predict or control.
Readers are cautioned not to put undue reliance on forward looking statements.

ZEMEX CANADA CORPORATION
NOTES TO THE BALANCE SHEET
SEPTEMBER 30, 1998
- --------------------------------------------------------------------------------
 
1.  BASIS OF PRESENTATION
 
    Zemex Canada Corporation (the "Company") was incorporated on December 4,
    1997 under the Business Corporations Act (Ontario). The Company is a
    wholly-owned subsidiary of Zemex Corporation ("Zemex"), a New York Stock
    Exchange listed company headquartered in Toronto, Canada. By articles of
    continuance dated June 5, 1998, the Company was continued under the Canada
    Business Corporations Act. The Company has been incorporated and organized
    for the purposes of facilitating a merger with Zemex which will result in a
    change of Zemex's domicile from the United States to Canada. The pro forma
    effect of this transaction, and a complete description of the merger has
    been disclosed in registration statement No. 333-65307. The transaction is
    summarized in Note 2 below.
 
    Statements of operations and changes in financial position are not included
    with the accompanying balance sheet as all aspects of the Company's
    operations and cash flows are readily apparent from financial information
    presented.
 
2.  SUBSEQUENT EVENT
 
    Under the terms of a merger agreement dated October 1, 1998, the Company
    will merge a newly-formed subsidiary which is incorporated under the laws of
    Delaware (the "Delaware subsidiary"), with and into Zemex (the
    "Reincorporation Merger"). The separate corporate existence of the Delaware
    subsidiary will cease, and Zemex will be the surviving corporation. Each
    previously outstanding share of the Delaware subsidiary's common stock will
    be converted into one share of Zemex common stock and each previously
    outstanding share of Zemex common stock will be converted into the right to
    receive one Company common share. The previously outstanding Company common
    shares will be canceled. As a result, Zemex will become a wholly-owned
    subsidiary of the Company and the current stockholders of Zemex will own the
    outstanding Company common shares. For accounting purposes, the assets and
    liabilities of the Company and its subsidiaries on a consolidated basis
    immediately after the consummation of the merger will be substantially
    identical to the assets and liabilities of Zemex and its subsidiaries on a
    consolidated basis immediately prior to the merger.

    Agreement and Plan of Merger dated as of October 1, 1998, by and among Zemex
Canada Corporation, a Canadian corporation (the "Company"), Zemex Acquisition
Corporation, a Delaware corporation and a subsidiary of the Company ("Mergeco"),
and Zemex Corporation, a Delaware corporation ("Zemex").
 
    Whereas, the respective Boards of Directors of Zemex, Mergeco and the
Company have approved the merger of Mergeco into Zemex and the other
transactions contemplated hereby on the terms and subject to the conditions set
forth herein; and
 
    Whereas, in furtherance thereof, upon the terms and subject to the
conditions of this Agreement, (i) Mergeco would be merged (the "Merger") with
and into Zemex in accordance with the General Corporation Law of the State of
Delaware (the "DGCL") and (ii) each share of common stock, par value US$1.00 per
share, of Zemex (collectively, the "Shares"), issued and outstanding immediately
prior to the Effective Time would, except as otherwise expressly provided
herein, be converted into the right to receive the Merger Consideration.
 
    Now, therefore, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, Zemex,
Mergeco and the Company agree as follows:
 
                                   ARTICLE I
                                   THE MERGER
 
      Section 1.01  THE MERGER.  Upon the terms and subject to the satisfaction
or waiver of the conditions hereof, and in accordance with the applicable
provisions of this Agreement and the DGCL, at the Effective Time Mergeco shall
be merged with and into Zemex. As of and following the Effective Time, the
separate corporate existence of Mergeco shall cease and Zemex shall continue as
the surviving corporation (the "Surviving Corporation").
 
      Section 1.02  EFFECTIVE TIME; CLOSING.  As soon as practicable after the
satisfaction or waiver of the conditions set forth in Article V, Zemex and
Mergeco shall execute in the manner required by the DGCL and deliver to the

as may be required by law to make the Merger effective. The time the Merger
becomes effective in accordance with applicable law is referred to as the
"Effective Time." Prior to such filing, a closing (the "Closing") shall be held
at the offices of Stikemen Elliott, Commerce Court West, Suite 5300, Toronto,
Ontario, Canada M5L 1B9, or such other place as the parties hereto shall agree,
for the purpose of confirming the satisfaction or waiver of the conditions set
forth in Article V. The date on which the Closing occurs is referred to herein
as the "Closing Date."
 
      Section 1.03  EFFECTS OF THE MERGER; SUBSEQUENT ACTIONS.  The Merger shall
have the effects set forth in Section 259 of the DGCL. Without limiting the
generality of the foregoing, and subject thereto and any other applicable laws,
at the Effective Time, all properties, rights, privileges, powers and franchises
of Zemex and Mergeco shall vest in the Surviving Corporation, and all debts,
liabilities, restrictions, disabilities and duties of Zemex and Mergeco shall
become debts, liabilities, restrictions, disabilities and duties of the
Surviving Corporation.
 
      Section 1.04  CERTIFICATE OF INCORPORATION AND BY-LAWS OF THE SURVIVING
CORPORATION.
 
        (a) The Certificate of Incorporation of Mergeco, as in effect
    immediately prior to the Effective Time, shall be the Certificate of
    Incorporation of the Surviving Corporation, until thereafter amended in
    accordance with the provisions thereof and hereof and applicable law;
    provided, however, that the name of the Surviving Corporation shall, in

      Section 1.05  DIRECTORS.  Subject to applicable law, the directors of

the holders of the following securities, each Share issued and outstanding

    represented Shares. Upon the surrender of each such Certificate formerly
    representing Shares, together with a properly completed letter of
    transmittal described in Section 1.10(b) below, the Exchange Agent shall

    by the number of Shares formerly represented by each such Certificate, in
    exchange therefor, and each such Certificate shall forthwith be canceled.

    transfer and that the person requesting such exchange shall pay to the
    Exchange Agent any transfer or other taxes required by reason of the
    delivery of the Merger Consideration to a person other than the registered
    holder of the Certificate surrendered, or shall establish to the

    applicable.
 
        (b) Promptly after the Effective Time, the Exchange Agent shall mail to
    each record holder of Certificates that immediately prior to the Effective
    Time represented Shares a letter of transmittal and instructions for use in
    surrendering such Certificates and receiving the Merger Consideration in
    exchange therefor.

    exchanged for the Merger Consideration as provided in this Section 1.10.
 
      Section 1.11  ZEMEX STOCK OPTION PLAN.  Effective as of the Effective

entitle the holder upon exercise to acquire an equivalent number of Company

       with respect to the preliminary proxy or information statement and cause

    occurring prior to, and including, the Effective Time, the Company will pay
    as incurred such Indemnified Party's legal and other expenses (including the
    cost of any investigation and preparation) incurred in connection therewith.
    The Company shall pay all expenses, including attorneys' fees, that may be
    incurred by any Indemnified Party in enforcing the indemnity and other

ITEM 20.  INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
    STATUTE.  Under the Canada Business Corporations Act, Zemex Canada may
indemnify a present or former director or officer of Zemex Canada or of another
corporation of which Zemex Canada is a stockholder or creditor against amounts
paid to settle civil, criminal or administrative actions or judgments and
expenses in connection therewith, where the director or officer was made a party
by reason of his position with Zemex Canada or such other corporation and
provided that the director or officer acted honestly and in good faith with a
view to the best interests of Zemex Canada and, in the case of a criminal or
administrative action or proceeding that is enforced by a monetary penalty, had
reasonable grounds for believing that his conduct was lawful. Such
indemnification may be made in connection with a derivative action only with
court approval. A director or officer is entitled to indemnification from Zemex
Canada as a matter of right if he was substantially successful on the merits and
fulfilled the conditions set forth above.
 
    BYLAWS.  The Bylaws of Zemex Canada provide that, subject to limitations
contained in the Canada Business Corporations Act, Zemex Canada shall indemnify
a director or officer of Zemex Canada, a former director or officer of Zemex
Canada or a person who acts or acted at Zemex Canada's request as a director or
officer of a body corporate of which Zemex Canada is or was a shareholder or
creditor against all costs, charges and expenses reasonably incurred in respect
of any civil, criminal or administrative action or proceeding to which such
person is made a party by reason of being or having been a director or officer
of Zemex Canada or such body corporate if such director or officer (a) acted
honestly and in good faith with a view to the best interests of Zemex Canada and
(b) in the case of a criminal or administrative action or proceeding that is
enforced by a monetary penalty, had reasonable grounds for believing that his or
her conduct was lawful. Notwithstanding the foregoing, Zemex Canada shall
indemnify any person referred to above in such other circumstances as the Canada
Business Corporations Act permits or requires.
 
    The Bylaws further provide that Zemex Canada may purchase and maintain
insurance for the benefit of any person referred to above as Zemex Canada's
board of directors may from time to time determine.

ITEM 22.  UNDERTAKINGS
 
    (a) That, for purposes of determining any liability under the Securities Act
of 1933, each filing of the registrant's annual report pursuant to section 13(a)
or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in the registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
    (b) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
    (c) The registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (b) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the registration statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
    (d) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
    (e) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
    (f) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
 
                                      II-4
<PAGE>
    (g) The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

                                  ZEMEX CORPORATION

                                 STOCK INCENTIVE PLAN


     1.   PURPOSE.  The purpose of this plan ("Plan") is to promote the
interests of ZEMEX CORPORATION (the "Corporation") by affording its key
employees and members of the Board of Directors of the Corporation ("Board") who
are not employees of the Corporation or one of its subsidiaries (each such
person a "Non-Employee Director") an incentive, by means of an opportunity to
acquire Capital Stock, par value $1.00 per share, of the Corporation ("Common
Stock") and to share in the increase in the value of the Common Stock, to remain
associated with the Corporation and to exert their maximum efforts in its
behalf.

     2.   ADMINISTRATION.  The Plan shall be administered by the Executive
Compensation/Stock Option/Pension Committee ("Committee") of the Board.  In
addition to its duties with respect to the Plan stated elsewhere in the Plan,
the Committee shall have full authority, consistently with the Plan, to
interpret the Plan, to promulgate such rules and regulations with respect to the
Plan as it deems desirable and to make all other determinations necessary or
desirable for the administration of the Plan.  All decisions, determinations and
interpretations of the Committee shall be binding upon all persons.

     3.   SHARES SUBJECT TO THE PLAN.  The aggregate number of shares of Common
Stock which may be covered by stock options ("Options") and stock appreciation
rights ("SARs") granted pursuant to the Plan is the greater of 450,000 shares or
ten percent (10%) of the then outstanding shares of Common Stick, subject to
adjustment under Section 7.  Shares which may be delivered on exercise or
settlement of Options or SARs may be previously issued shares re-acquired by the
Corporation or authorized but unissued shares.  Shares covered by Options that
are forfeited, cancelled, or that otherwise expire unexercised (without having
been surrendered upon the exercise of SARs, whether settled in cash or Common
Stock) shall again be available for grant under the Plan.

     4.   ELIGIBILITY.  The Committee shall from time to time in its discretion
select the employees to whom Options and/or SARs, shall be granted from among
the key employees of the Corporation and its subsidiary corporations
("Subsidiaries"), and such selected employees ("Participants") shall be eligible
to receive any benefit available under this Plan.  Non-Employee Directors are
eligible only to receive Options under Section 12 of this Plan.  Unless
otherwise provided, administrative provisions applicable to Participants are
applicable to Non-Employee Directors.

     5.   OPTIONS.

          (a)  Except as otherwise provided in Section 12 of this Plan, the
Committee shall in its discretion determine the time or times when Options shall
be granted and the number of shares of Common Stock, to be subject to each
Option.  In the case of an incentive stock option, as defined


<PAGE>

in Section 422(b) of the Internal Revenue Code of 1986, as amended (the "Code"),
the aggregate fair market value (determined as of the date the Option is
granted) of the stock for which options may become exercisable by any
Participant for the first time during any calendar year (under all stock option
plans of the Corporation and its Subsidiaries) shall not exceed $100,000.
Options may be granted under the Plan on such terms and conditions as the
Committee considers appropriate, which may differ from those provided in the
Plan, where such Options ("Substitute Options") are granted in substitution for
stock options held by employees of other companies who concurrently become
employees of the Corporation or a Subsidiary as the result of a merger or
consolidation of the employing company with, or the acquisition of the property
or stock of the employing company by, the Corporation or a Subsidiary.

          (b)  Except as provided in paragraph (d) or in Section 12 of this
Plan, each Option shall be for such term as the Committee shall determine, but
not more than 10 years from the date it is granted, except that the term of an
Option other than an incentive stock option may extend up to 11 years from the
date the Option is granted if the Participant dies within the 10th year
following the date of grant.

          (c)  Except as provided in paragraphs (a) and (d), the purchase price
for each share of Common Stock subject to an Option shall be the fair market
value of the Common Stock on the date the Option is granted, defined as the
closing price of a share of Common Stock of the Corporation on the New York
Stock Exchange on the date of grant or, if no trade occurs on such date, on the
day next preceding such date on which the Common Stock was traded.

          (d)  In the case of an incentive stock option, as defined in
Section 422(b) of the Code, granted to an employee who at the time the Option is
granted owns (within the meaning of Section 422(b)(6) of the Code) stock
possessing more than 10 percent of the total combined voting power of all
classes of stock of the corporation employing such employee or of its parent
corporation or a subsidiary corporation (as defined in Sections 424(e) and
424(f), respectively, of the Code), the purchase price for each share of Common
Stock subject to the Option shall be at least 110 percent of the fair market
value of the share at the time such Option is granted and such Option shall not
be exercisable after the expiration of five years from the date such Option is
granted.

          (e)  Exercise of an Option shall be by written notice in the form and
manner determined by the Committee.  Except as otherwise determined by the
Committee, no Option may be exercised to any extent before one year from the
date of grant.  The Committee in its discretion may (1) determine installment
exercise terms for an Option under which it may be exercised in a series of
cumulative installments, (2) prescribe rules limiting the frequency of exercise
of Options or the minimum number of shares that may be exercised at any one
time, (3) determine the form of consideration (including cash, shares of Common
Stock valued at fair market value as of the date of exercise, or any combination
of cash and shares of Common Stock) which may be accepted in payment of the
purchase price of shares purchased pursuant to the exercise of an Option, and
(4) prescribe such other rules or conditions as it considers appropriate
regarding the exercise of Options granted under the Plan.


                                         -2-

          (f)  In the case of incentive stock options, the instruments
evidencing such Options shall provide that if, within two years from the date of
grant of the Option or within one year after the transfer of shares of Common
Stock to the Participant on exercise of the Option, the Participant makes a
disposition (as defined in Section 424(c) of the Code) of any shares of such
Common Stock, the Participant shall notify the Corporation of such disposition
in the manner and within the time as the Committee in its discretion shall
determine.  The Committee may direct that a legend restricting transfer in the
absence of appropriate notification be affixed to any stock certificates
representing Common Stock transferred under the Plan.

          (g)  Each Option shall be evidenced by a written instrument which
shall state such terms and conditions which are not inconsistent with the
provisions of the Plan as the Committee in its sole discretion shall determine
and approve, including terms and conditions regarding the exercise of Options
upon termination of employment.

     6.   STOCK APPRECIATION RIGHTS.  The Committee may from time to time grant
SARs unrelated to Options or related to Options or portions of Options granted
to Participants under the Plan.  Each SAR shall be evidenced by a written
instrument and shall be subject to such terms and conditions as the Committee
may determine.  The Participant may exercise an SAR or portion thereof, and
thereupon shall be entitled to receive payment of an amount equal to the
aggregate appreciation in value of the shares as to which the SAR is awarded, as
measured by the difference between the purchase price of such shares and their
fair market value at the date of exercise.  Such payments may be made in cash,
in shares of Common Stock valued at fair market value as of the date of
exercise, or in any combination thereof, as the Committee in its discretion
shall determine.

     7.   ADJUSTMENT UPON CHANGES IN CAPITALIZATION.  If there is a change in
the number of kind of outstanding shares of the Corporation's stock by reason of
a stock dividend, stock split, recapitalization, merger, consolidation,
combination or other similar event, or if there is a distribution to
shareholders of the Corporation's Common Stock other than a cash dividend,
appropriate adjustments shall be made by the Committee to the number and kind of
shares subject to the Plan; the number and kind of shares under Options and/or
SARs then outstanding; the maximum number of shares available for Options and/or
SARs; the purchase price for shares of Common Stock covered by Options; and
other relevant provisions, to the extent that the Committee, in its sole
discretion, determines that such changes make such adjustments necessary to be
equitable.  Similar adjustments may also be made by the Committee in its
discretion if Substitute Options are granted pursuant to Section 5(a).

     8.   TRANSFER OF OPTIONS AND SARS.  Options and SARs shall be nonassignable
and nontransferable by the Participant other than by will or the laws of descent
and distribution, and shall be exercisable during a Participant's lifetime only
by the Participant or his agent, attorney-in-fact, or guardian.

     9.   LAWS AND REGULATIONS.  The Plan, the grant and exercise of Options and
SARs, and the obligation of the Corporation to sell or deliver shares of Common
Stock under the Plan shall be subject to all applicable laws, regulations and
rules.


                                         -3-

     10.  NO EMPLOYMENT RIGHTS.  Nothing in the Plan shall confer upon any
employee of the Corporation or a Subsidiary any right to continued employment,
or interfere with the right of the Corporation or a Subsidiary to terminate his
or her employment at any time.

     11.  TAX WITHHOLDING.  Any payment to or settlement with a Participant or
Non-Employee Director in cash, or in Common Stock, pursuant to any provision of
the Plan shall be subject to withholding of income tax, FICA tax or other taxes
to the extent the Corporation or a Subsidiary is required to make such
withholding.  Any required withholding payable by a Participant or Non-Employee
Director with respect to any tax may be paid in whole shares of Common Stock or
in a combination of whole shares of Common Stock and cash, having an aggregate
fair market value equal to the amount of any required withholding obligation.

     12.  NON-EMPLOYEE DIRECTORS' OPTIONS.  Each Non-Employee Director who
serves as such at the close of business on May 27, 1993 shall automatically be
granted at the close of business on such date Options to purchase 15,000 shares
of Common Stock.  Each person who becomes a Non-Employee Director after May 27,
1993 shall automatically be granted Options to purchase 15,000 shares of Common
Stock at the close of business on the date of such person's initial election as
a Director.  All such Options shall be nonstatutory stock options.

     Except as set forth below, fifty percent (50%) of the total number of the
shares subject to Options granted to a Non-Employee Director shall become
exercisable on the first anniversary of the date of grant and fifty percent
(50%) on the second anniversary of the date of grant.  The right to purchase
shares with respect to Options which have become exercisable shall be cumulative
during the term of the Options.  The Options may be exercised (i) for a period
of five years after they  first become exercisable, provided that during such
period the Non-Employee Director remains a member of the Board, and (ii) for a
period of six months following retirement as a Non-Employee Director, provided
that only those Options exercisable at the date of the Non-Employee Director's
retirement as a Non-Employee Director may be exercised during the period
following retirement and, provided further, that in no event shall the Options
be exercisable more than ten (10) years after the date of grant.  In the event
of the death of a Non-Employee Director, the Options shall be exercisable only
within the twelve (12) months next succeeding the date of death, and then only
(i) by the executor or administrator of the Non-Employee Director's estate or by
the person or persons to whom the Non-Employee Director's rights under the
Options shall pass by the Non-Employee Director was entitled to exercise the
Options at the date of the Non-Employee Director's death, provided that in no
event shall the Options be exercisable more than ten (10) years after the date
of grant.

     13.  TERMINATION; AMENDMENTS.

          (a)  The Board may at any time terminate the Plan.  Unless the Plan
shall previously have been terminated by the Board, it shall terminate on
May 26, 2003.  No Option or SAR may be granted after such termination.


                                         -4-
<PAGE>

          (b)  The Board may at any time or times amend the Plan or amend any
outstanding Options and/or SARs for the purpose of satisfying the requirements
of any changes in applicable laws or regulations or for any other purpose which
at the time may be permitted by law, provided that no amendment of any
outstanding Options and/or SARs shall contain terms or conditions inconsistent
with the provisions of the Plan as determined by the Committee, and provided
further that Section 12 shall not be amended more frequently than once every six
months, except as required to comply with the Internal Revenue Code, ERISA, or
other statute.

          (c)  Except as provided in Section 7, no such amendment shall, without
the approval of the shareholders of the Corporation:  (i) increase the maximum
number of shares of Common Stock for which Options or SARs may be granted under
the Plan; (ii) except to the extent required or permitted under Section 5(a) in
the case of Substitute Options, reduce the price at which Options may be granted
below the price provided for in Section 5(c); (iii) reduce the Option Price of
outstanding Options; (iv) extend the period during which Options or SARs may be
granted; (v) except to the extent permitted or required under Section 5(a) in
the case of Substitute Options, extend the period during which an outstanding
Option may be exercised beyond the maximum period provided for in Section 5(b);
(vi) materially increase in any other way the benefits accruing to Participants;
or (vii) change the class of persons eligible to be Participants.

     14.  EFFECTIVE DATE.  The Plan shall become effective upon approval by the
Board; provided, however, that the Plan shall be submitted to the shareholders
for approval, and if not approved by the shareholders within one year from the
date of approval by the Board shall be of no force and effect.  Options and SARs
granted hereunder before approval of the Plan by the shareholders shall be
granted subject to such approval and shall not be exercisable or payable before
such approval.  Options or SARs may be granted by the Committee or other actions
may be taken under or with respect to the Plan, pursuant to any Plan amendment
that is subject to shareholder approval, prior to the receipt of such
shareholder approval, provided that such Options or SARs, shall not be
exercisable or payable before such approval.
