Dear Fellow Stockholder:

      You are cordially invited to attend the 2000 Annual Meeting of
Stockholders of Minerals Technologies Inc., which will be held on Thursday, May

270 Park Avenue (between 47th and 48th Streets), New York, New York 10017.

      At this year's meeting, you will be asked to consider and to vote upon the
election of three directors. Your Board of Directors unanimously recommends that
you vote FOR the nominees.

      You will also be asked to ratify the appointment of KPMG LLP as our
independent auditors for the 2000 fiscal year. The Board continues to be pleased
with the services KPMG LLP has rendered to Minerals Technologies, and
unanimously recommends that you vote FOR this proposal.

      The two items upon which you will be asked to vote are discussed more
fully in the Proxy Statement. I urge you to read the Proxy Statement completely
and carefully so that you can vote your interests on an informed basis.

      Your vote is important! Whether or not you plan to attend the meeting, and
regardless of the number of shares you own, your representation and vote are
very important and you should vote your shares. Therefore, I urge you to
complete, sign, date and return the enclosed proxy card promptly in the
accompanying postage prepaid envelope. All shareholders of record, and many
street name holders, may also vote by Internet, or by touchtone telephone from
the United States and Canada, using the instructions on the proxy card. If you
return a signed proxy without marking it, it will be voted in accordance with
management's recommendations. You may, of course, attend the Annual Meeting and
vote in person, even if you have previously submitted a proxy.

                                                Sincerely,

      Minerals Technologies Inc. is sending this Proxy Statement and form of

you do not attend the meeting, your shares will be counted as present at the
meeting and voted as you direct.

      At the Annual Meeting, stockholders will vote on two questions: the
election of directors, and ratification of the appointment of auditors. The
Board unanimously recommends that you vote for each of the nominees for
director, Kristina M. Johnson, Paul M. Meister and Michael F. Pasquale, and for

person owned of record, or, to our knowledge, owned beneficially, more than 5%
of our common stock.

      If you submit a proxy, you can revoke it at any time before it is voted by
submitting a written revocation or a new proxy, or by voting in person at the
Annual Meeting.

                         ITEM 1 -- ELECTION OF DIRECTORS

      The Board of Directors is divided into three classes. One class is elected
each year for a three-year term. This year the Board has nominated Paul M.
Meister and Michael F. Pasquale, who are now directors of Minerals Technologies,
and Kristina M. Johnson, to serve for a three-year term expiring at the Annual
Meeting of Stockholders to be held in 2003.

      The Board expects that the nominees will be available for election. If one
or more nominees become unavailable, your proxy would be voted for a nominee or
nominees who would be designated by the Board, unless the Board reduces the
number of directors.

      The Board of Directors unanimously recommends a vote FOR election of each
of Kristina M. Johnson, Paul M. Meister and Michael F. Pasquale as a Director.

                 BOARD OF DIRECTORS, COMMITTEES AND COMPENSATION

      The Board of Directors met seven times in 1999. All of the directors
attended 75 percent or more of the meetings of the Board and committees on which
they served in 1999.

The Compensation and Nominating Committee

      The Compensation and Nominating Committee consists of Mr. Curcio (Chair),
Mr. Lurie and Mr. Meister, who are not employees of Minerals Technologies. The
Compensation and Nominating Committee met four times in 1999.

      The primary functions of the Compensation and Nominating Committee are:

o  To participate in the development of our compensation policies;
o  To establish, and from time to time vary, the salaries and other
   compensation of our employee-directors and other elected officers;
o  To review proposed changes in our compensation policy at all levels; and
o  To bring forward the names of suitable candidates for election to the Board.

The Audit Committee

      The Audit Committee consists of Mr. Pasquale (Chair), Mr. Golub and Mr.
Steere, who are not employees of Minerals Technologies. The Board of Directors
has determined that each of the members of the Audit Committee is independent
and financially literate in accordance with the rules of the New York Stock
Exchange. The Board of Directors has also determined that at least one member of
the Audit Committee has financial management expertise. The Audit Committee met
four times in 1999.

      The Board of Directors has reviewed, assessed the adequacy of and approved
a formal written charter for the Audit Committee. The full text of the Charter
of the Audit Committee appears as an appendix to this Proxy Statement.

      The primary duties of the Audit Committee are:

o  To serve as an independent and objective party to monitor Minerals
   Technologies' financial reporting processes, internal control system, and
   legal compliance system;
o  To review and appraise the audit efforts of our independent auditors and
   internal auditing department; and
o  To provide an open avenue of communication among the independent auditors,
   financial and senior management, the internal auditing department and the
   Board.

      In addition to four regularly scheduled meetings annually, the Audit
Committee is available either as a group or individually to discuss any matters
that might affect the financial statements, internal controls or other financial
aspects of the operations of Minerals Technologies.

Director Compensation

Fees

      Each of the directors, other than directors who are officers or employees
of Minerals Technologies, receives an annual retainer fee of $10,000 for serving
as a director, $1,000 for serving as a member of a committee of the Board, and
an additional $1,000 if serving as a committee chair. Non-employee directors
also receive a fee of $2,000 for each meeting of the Board they attend and $500
for each committee meeting they attend. Directors also receive compensation
under the plans described below.

Nonfunded Deferred Compensation and Unit Award Plan for Non-Employee Directors

      Under the Nonfunded Deferred Compensation and Unit Award Plan for
Non-Employee Directors, directors who are not employees of Minerals Technologies
have the right to defer their fees. At each director's election, his or her
deferred fees will be credited to his or her account either as dollars or as
units which have the economic value of one share of Minerals Technologies stock.
Dollar balances in a director's account bear interest at a rate of return equal
to the rate of return for the Fixed Income Fund in the Minerals Technologies
Inc. Savings and Investment Plan. If a director elects to have his or her
deferred fees credited to his or her account as units, the number of units
credited is calculated by dividing the amount of the deferred fees by the
closing price of our common stock as of the last business day prior to the date
on which the fees would otherwise be paid.

      Each non-employee director is credited with 400 units upon first joining
the Board and with an additional 400 units each year as of the date of the
Annual Meeting of Stockholders, plus 50 units each year for serving as a member
of a committee of the Board and an additional 15 units for serving as chair of a
committee. In addition, each member receives 15 units for attending any
committee meeting and an additional 10 units for serving as chair of a committee
meeting.

      The units in a director's account are increased by the value of any
dividends on our common stock. In the case of cash dividends, the units are
increased by a number calculated by multiplying the cash dividend per share
times the number of units in the director's account on the related dividend
record date and dividing the result by the closing market price of the common
stock on the dividend payment date. In the case of stock dividends, the units
would be increased by a number calculated by multiplying the stock dividend per
share times the number of units in the director's account on the related
dividend record date.

      At the time of the director's termination of service on the Board, the
amount held in his or her account is payable in cash only. Based on the
director's prior choice to accumulate dollars or units as described above, the
director receives either (i) the amount of his or her deferred fees plus accrued
interest, or (ii) an amount determined by multiplying the number of units in his
or her account by the closing market price of the common stock on the last
business day prior to the date of payment. Payments are made in a lump sum or in
installments, at the election of the director.

Stock and Incentive Plan

      Directors are eligible under the Minerals Technologies Stock and Incentive
Plan to receive options to purchase common stock, at the same time and on the
same basis as options are granted to Minerals Technologies' U.S.-based employees
"across-the-board."

Savings and Investment Plan and the Minerals Technologies Inc. Non-Funded Deferred Compensation and Supplemental Savings Plan on behalf of the named executive officer. (b) Mr. Bardach joined Minerals Technologies as Vice President-Finance and Chief Financial Officer in August 1998. At that time we agreed to pay Mr. Bardach a joining bonus, half to be paid in 1998, and half to be paid in 1999 if certain conditions were met. These amounts are included in the table above in the column headed "Bonus." 11 Option Grants in Last Fiscal Year This table provides information on options granted to the named executive officers on January 28, 1999 as part of a grant of 1,321,235 options to all U.S. employees (and certain key foreign employees) of Minerals Technologies and its subsidiaries. The last three columns of the table show the potential realizable value of the options in each of three hypothetical cases. The first case assumes no increase in the price of the underlying Minerals Technologies stock over the ten-year term of the options. The second case assumes that the price of the stock increases at a rate of five per cent per year over the term of the options, which would result in a price of approximately $64.39 per share in 2009 and an increase in aggregate shareholder value of approximately $519 million. The third case assumes that the price of the stock increases at a rate of ten per cent per year over the term of the options, which would result in a price of approximately $102.53 per share in 2009 and an increase in aggregate shareholder value of approximately $1,314 million. The actual market value of the stock at any future date may or may not correspond to any of these hypothetical cases.

13 REPORT OF THE COMPENSATION AND NOMINATING COMMITTEE ON EXECUTIVE COMPENSATION The following report of the Compensation and Nominating Committee of the Board sets forth the Committee's policies applicable to the executive officers of Minerals Technologies. This report is provided by the Compensation and Nominating Committee of the Board of Directors. The members of the Compensation and Nominating Committee, whose names follow this report, are independent outside directors who are not employees of Minerals Technologies, and none serves as a member of the compensation committee of any company that has an executive officer who also serves as a director of Minerals Technologies. In 1999, the Compensation and Nominating Committee adhered to its policy that compensation programs should reward the achievement of the short-term and long-term goals and objectives of Minerals Technologies, and that compensation should be related to the value created for its stockholders. The Committee sets high performance targets and rewards their achievement with compensation that is above the average, but within the range of, compensation of similarly placed executives in manufacturing firms of comparable size. Consistent with this policy, each elected corporate officer's annual compensation is determined by applying to the previous year's compensation an annual increase, and an incentive payment, determined as stated below in this report. Base Pay Each employee of Minerals Technologies receives an annual performance rating, which may range from "consistently below expectations" to "consistently exceeds expectations," with several possible intermediate ratings. The performance rating of the Chairman and Chief Executive Officer is assigned by the Compensation and Nominating Committee and approved by the Board. The performance ratings of the other elected corporate officers, including those named in the Summary Compensation Table appearing in this proxy statement (the "principal executives"), are assigned by the Chairman and Chief Executive Officer and reviewed by the Compensation and Nominating Committee. Based on Minerals Technologies' performance, general business outlook and industry compensation trends, management each year sets a guideline corporate-wide average percentage compensation increase for all employees for the coming year. The percentage increase received by a particular employee is determined on the basis of the employee's performance rating and current compensation level within the range established for the employee's position and may range from no increase, if the performance rating is "consistently below expectations," to up to twice the corporate-wide average increase referred to above, if the performance rating is "consistently exceeds expectations." This procedure was followed to determine the annual increase for 1999 received by all employees, including Dr. J.-P. Valles, the Chairman and Chief Executive Officer, and each of the other principal executives. Dr. Valles received a base pay increase of 7.00%, reflecting the Committee's and the Board's belief that his performance during 1999 consistently exceeded expectations. 14 Incentive Payment Subsequent to the above adjustment, 25% of each elected corporate officer's salary for the coming year is withheld as part of Minerals Technologies' incentive payment program. Depending upon the extent to which the company's performance during the year meets targets established by the Board, as little as 40% of the amount withheld from his salary or as much as 200% will be returned to each elected corporate officer. These payments, which are made in the following year, are shown as the Bonus for each principal executive in the year to which they are attributable in the Summary Compensation Table included in this proxy statement. This incentive program is intended to more closely link the principal executives' pay to the growth of the company and the value created for stockholders in the preceding year, as measured by four factors: sales growth as compared to target; net income growth as compared to target; return on equity as compared to target; and percentage growth in Minerals Technologies common stock value as compared to percentage growth in the S & P Midcap Basic Materials Index. At the beginning of each year, the Board establishes a target for each of these factors and sets up a scoring system to measure at year-end the extent to which each target is met. At year-end, a formula is applied to the weighted average of the scores achieved and each principal executive's performance rating to determine the level of the incentive payment to be received by the principal executive. The Compensation and Nominating Committee then considers whether there are other factors that should also be taken into consideration in establishing the overall level of compensation of each principal executive. They will, for example, take into consideration actions that have been taken by management to benefit shareholders in the longer term that may have negative impact on the factors listed above. During 1999, Minerals Technologies exceeded all of the targets except for the sales growth target. This resulted in positive adjustments to the incentive payments. The formula produced a payment of $450,007 for Dr. Valles, and the Compensation and Nominating Committee agreed that he should receive that amount as his 1999 incentive payment, to be paid in 2000. Stock Options The Compensation and Nominating Committee intends to grant an option to purchase Minerals Technologies common stock to the principal executives on a regular basis. In addition, special grants may be made to reflect extraordinary achievements or in connection with important promotions. The grants that were made to the principal executives in January 1999, three years following the last such grant in 1996, were made pursuant to the recommendation of an independent consultant in the field of executive compensation. The Committee had engaged the consultant to assist it in reviewing practices for the granting of stock options to key employees in industry generally, and establishing guidelines for future grants based on those practices. Under these guidelines, each of the principal executives was granted an option to purchase a number of shares which when multiplied by the option price equals a given multiple of the executive's total compensation. The guidelines establish multiples which are intended to ensure that the total compensation package offered, including both short- and long-term incentive payments, is competitive with the firms with which Minerals Technologies competes for executive employees. In addition to making grants to key executives, Minerals Technologies believes that, where practical and economical, all employees should have the opportunity to participate in the future 15 growth of the firm through equity participation. The Committee has therefore established a practice of making grants to all U. S.-based employees, also on a regular basis, and did so in January 1999. Discretionary Authority of the Committee The Compensation and Nominating Committee believes that the application of the procedures described above will generally result in fair and adequate compensation to each principal executive. However, the Compensation and Nominating Committee also believes that no arbitrary formula is an adequate substitute for individual judgments in all cases, particularly in determining the value of a principal executive's contribution to the success of the company. Therefore, the Compensation and Nominating Committee may from time to time use its discretion in deviating from the above procedures (including, possibly, modifying the factors discussed above or varying their weighting) to set compensation levels for the principal executives and others that best serve the interests of the company and its stockholders. Internal Revenue Code Section 162(m) Internal Revenue Code Section 162(m) and regulations thereunder, which limit the deductibility of certain executive compensation in excess of $1,000,000, did not result in any disallowance of a deduction for compensation payments made by Minerals Technologies for the 1999 fiscal year. However, the Compensation and Nominating Committee has determined that, in order to retain the discretion referred to in the previous paragraph, it reserves the right to make compensation payments that in part may not qualify for a tax deduction because of the limitations of Internal Revenue Code Section 162(m). John B. Curcio, Chair William L. Lurie Paul M. Meister Compensation Committee Interlocks and Insider Participation Throughout 1999 the Compensation and Nominating Committee was composed of Mr. Curcio (Chair), Mr. Lurie and Mr. Meister. None of the members of the Committee is or has ever been an officer or employee of Minerals Technologies or any of its subsidiaries. During 1999 no executive officer of Minerals Technologies served as a director or a member of the compensation committee of another entity, any of whose executive officers served as a member of the Compensation and Nominating Committee. In addition, no executive officer of Minerals Technologies served as a member of the compensation committee of another entity, any of whose executive officers served as a director of Minerals Technologies. 16 Performance Graph This line graph compares Minerals Technologies' cumulative total stockholder return with the S&P 500 Index, as a performance indicator for the overall stock market, and the S&P Midcap Basic Materials Index, a published industry index. The starting point for the comparison is a hypothetical investment of $100 in our common stock and in each of the indexes at the close of the last trading day of 1994.

17 Employment, Termination and Change-in-Control Arrangements Employment Agreements In October 1997, Minerals Technologies entered into an employment agreement with Dr. Valles for a term expiring October 17, 2001, and for an annual base salary of not less than $738,972. In October 1998, Minerals Technologies entered into employment agreements with the following individuals for terms of three years and for not less than the annual base salaries indicated: Mr. Saueracker, $241,146; Mr. Dulski, $233,352; and Mr. Gray, $209,576. In October 1999, Minerals Technologies entered into an employment agreement with Mr. Bardach for a term of two years and for an annual base salary of not less than $247,500. Each of the named executive officers may also receive salary increases and annual bonuses in amounts to be determined by the Board or the Compensation and Nominating Committee. The agreements also entitle the named executive officers to participate in employee benefit plans and other fringe benefits that are generally available to our executive employees. Under the agreements, each named executive officer has agreed to comply with certain customary provisions, including covenants not to disclose our confidential information at any time and not to compete with our business during the term of the agreement and, subject to our continued payment of amounts under the agreement, for two years thereafter. We may terminate the employment agreements before the end of the specified term of employment for "cause" as defined in the agreements. Severance Agreements Minerals Technologies has entered into severance agreements with certain of its executive officers, including each of the named executive officers. The agreements continue through December 31 of each year, and are automatically extended in one-year increments unless we choose to terminate them. If a change in control occurs, the severance agreements are effective for a period of four years from the end of the then existing term. These agreements are intended to provide for continuity of management in the event of a change in control of Minerals Technologies. If, following a change in control, the executive is terminated by Minerals Technologies for any reason, other than for disability, death, retirement or for cause (as defined in the agreements), or if the executive terminates his or her employment for good reason (as defined in the agreements), then the executive is entitled to a severance payment of 2.99 times the executive's base amount (as defined in the agreements). The severance payment generally will be made in a lump sum. For a period of up to two years following a termination that entitles an executive to severance payments, Minerals Technologies will provide life, disability, accident and health insurance coverage substantially similar to the benefits provided before termination, except to the extent such coverages would result in an excise tax being imposed under Section 4999 of the Internal Revenue Code. The agreements also provide that upon the occurrence of certain stated events that constitute a "potential change in control" of Minerals Technologies, the executive agrees not to voluntarily terminate his employment with Minerals Technologies for a six-month period. Under the severance agreements, a change in control includes any of the following events unless approved by the Board: (i) we are required to report a "change in control" in accordance with the Securities Exchange Act of 1934; (ii) any person acquires 15% of our voting securities; (iii) a majority of our directors are replaced during a two-year period; or (iv) our stockholders approve a merger, liquidation or sale of assets. 18 Stock Option Plan The Stock and Incentive Plan provides that all non-vested stock options granted under the plan may, at the discretion of the Compensation and Nominating Committee, be made immediately exercisable upon the employee's retirement or upon a change in control of Minerals Technologies (as defined in the plan). Retirement Plans Each of the named executive officers is entitled to benefits under the defined benefit pension plans which we maintain. The Retirement Annuity Plan is a tax qualified pension plan which pays retirement benefits within the limits prescribed by the Internal Revenue Code. The Nonfunded Supplemental Retirement Plan is an unfunded, non-tax qualified pension plan which pays retirement benefits in excess of such tax limits. Benefits under the Retirement Annuity Plan and the Nonfunded Supplemental Retirement Plan are based upon an annuity equal to the greater of (i) 1.4% of a participant's career earnings or (ii) 1.75% of a participant's career earnings less 1.5% of primary Social Security benefits, multiplied by years of service up to 35 years. For purposes of this formula, a participant's "career earnings" are based on the average earnings for the five highest consecutive calendar years prior to January 1, 1999, and on actual earnings for periods after December 31, 1998. Under the Retirement Annuity Plan and the Nonfunded Supplemental Retirement Plan, each of the named executive officers would be entitled to the following annual benefits after retirement: Dr. Valles, $487,999; Mr. Saueracker, $142,416; Mr. Dulski, $115,087; Mr. Bardach, $75,121; and Mr. Gray, $93,785. This assumes that (i) payments will be made in the form of a 50% joint and survivor annuity; (ii) employment will be continued until normal retirement at age 65; and (iii) creditable compensation will continue at 1999 levels until retirement. Grantor Trust In order to secure the benefits accrued under the Nonfunded Supplemental Retirement Plan and the Nonfunded Deferred Compensation and Supplemental Savings Plan (an unfunded, non-tax qualified plan which pays amounts in excess of the limits which the Internal Revenue Code imposes on benefits under our Savings and Investment Plan), Minerals Technologies has entered into an agreement establishing a grantor trust within the meaning of the Internal Revenue Code. Under the Grantor Trust Agreement, we are required to make certain contributions of cash or other property to the trust upon the retirement of individuals who are beneficiaries of those plans; upon the occurrence of certain events defined as constituting a "Change of Control"; and in certain other circumstances. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Based solely on a review of our records and of copies furnished to us of reports under Section 16(a) of the Securities Exchange Act of 1934, or written representations that no such reports were required, we believe that, during the 1999 fiscal year, our officers, directors and greater than 10% shareholders complied with all applicable filing requirements. 19 PROCEDURAL MATTERS Casting and Counting of Votes Votes cast at the Annual Meeting (whether by proxy or in person) will be counted by an independent inspector of election appointed by Minerals Technologies. If a proxy form is returned properly signed but not marked, it will be voted according to management's recommendations on all proposals. The Board knows of no other business that will be presented at the Annual Meeting. The proxy confers discretionary authority with respect to any other matters which come before the Annual Meeting, and the individuals named in the proxy will vote in accordance with their judgment on such matters if they arise. Quorum The by-laws of Minerals Technologies state that a quorum for all meetings of stockholders consists of the holders of a majority of the shares of common stock issued and outstanding and entitled to vote, present in person or by proxy. The inspector of election will treat shares of common stock represented by a properly signed and returned proxy as present at the Annual Meeting for purposes of determining a quorum, whether the proxy is marked as casting a vote or abstaining. On the Record Date there were 20,655,452 shares of common stock issued and outstanding. The inspector of election will also treat shares represented by "broker non-votes" as present for purposes of determining a quorum. Broker non-votes are shares held in record name by brokers or nominees, as to which the broker or nominee (i) has not received instructions from the beneficial owner or person entitled to vote, (ii) does not have discretionary voting power under applicable New York Stock Exchange rules or the document under which it serves as broker or nominee, and (iii) has indicated on the proxy card, or otherwise notified us, that it does not have authority to vote the shares on the matter. Vote Required for Approval: Election of Directors The by-laws state that directors are to be elected by a plurality vote of the shares of stock present and entitled to vote, in person or by proxy, at the Annual Meeting. Abstentions and broker non-votes as to the election of directors will not affect the outcome of the election of directors. Vote Required for Approval: Other Questions The by-laws state that except as otherwise provided by law or in the Certificate of Incorporation or the by-laws, all questions other than the election of directors are determined by a majority of the votes cast on the question. All votes cast in favor of a given proposal, and all votes cast against it, are added together for a total sum of votes on that proposal. Abstentions and broker non-votes as to the proposal will not affect the outcome, as they will not be included in calculating the number of votes necessary for approval and will not count as votes cast for or against the question. Cost of Soliciting Proxies The cost of this solicitation is being borne by Minerals Technologies. In addition to soliciting proxies through the mail using this Proxy Statement, we may solicit proxies by telephone, facsimile, electronic mail and personal contact. These solicitations will be made by our regular employees without additional compensation. We have also engaged Morrow & Co., Inc. to assist in this solicitation of proxies, and we have agreed to pay that firm $4,000 for its assistance, plus expenses. 20 Stockholder Proposals The Compensation and Nominating Committee will consider nominations of candidates for director, and the Board of Directors will consider other items of business, which are proposed by stockholders. The by-laws describe the procedures which a stockholder must follow to nominate persons for election as directors or to introduce an item of business at a meeting of stockholders. These procedures provide that nominations for director and items of business to be introduced at an annual meeting of stockholders must be submitted in writing to the Secretary of Minerals Technologies at The Chrysler Building, 405 Lexington Avenue, New York, NY 10174-1901. If intended to be considered at an annual meeting, the nomination or proposed item of business must be received not less than 70 days nor more than 90 days in advance of the first anniversary of the previous year's annual meeting. Therefore, for purposes of the 2000 annual meeting, any nomination or proposal must have been received between February 27 and March 18, 2000. With respect to any other meeting of stockholders, the nomination or item of business must be received not later than the close of business on the tenth day following the date of our public announcement of the date of the meeting. The nomination or item of business must contain: o The name and address of the stockholder giving notice, as they appear in our books (and of the beneficial owner, if other than the stockholder, on whose behalf the proposal is made); o The class and number of shares of stock owned of record or beneficially by the stockholder giving notice (and by the beneficial owner, if other than the stockholder, on whose behalf the proposal is made); o A representation that the stockholder is a holder of record of stock entitled to vote at the meeting, and intends to appear at the meeting in person or by proxy to make the proposal; and o A representation whether the stockholder (or beneficial owner, if any) intends, or is part of a group which intends, to deliver a proxy statement and form of proxy to holders of at least the percentage of outstanding stock required to elect the nominee or approve the proposal and/or otherwise solicit proxies from stockholders in support of the nomination or proposal. Any notice regarding the introduction of an item of business at a meeting of stockholders must also include: o A brief description of the business desired to be brought before the meeting; o The reason for conducting the business at the meeting; o Any material interest in the item of business of the stockholder giving notice (and of the beneficial owner, if other than the stockholder, on whose behalf the proposal is made); and o If the business includes a proposal to amend the by-laws, the language of the proposed amendment. Any nomination of a candidate for director must also include: o A signed consent of the nominee to serve as a director, if elected; o The name, age, business address, residence address and principal occupation or employment of the nominee; o The number of shares of Minerals Technologies common stock beneficially owned by the nominee; and o Any additional information that would be required under the rules of the Securities and Exchange Commission in a proxy statement soliciting proxies for the election of that nominee as a director. 21 Under the rules of the Securities and Exchange Commission, if a stockholder proposal intended to be presented at the 2001 Annual Meeting is to be included in the proxy statement and form of proxy relating to that meeting, we must receive the proposal at our principal executive office no later than December 5, 2000.
