DIRECTORS AND OFFICERS



(A)(1)

Number, Quorum, Required Votes. The number of directors of the Corporation which shall constitute the whole Board of Directors shall at all times be not less than ten (10) nor more than fifteen (15). Subject to such minimum and maximum limitations, the number of directors shall be fixed by, or in the manner provided in, the by-laws. A majority of the whole Board of Directors shall constitute a quorum for the transaction of business. Unless this Certificate of Incorporation shall specifically require a vote of a greater number, the affirmative vote of a majority of the whole Board of Directors shall be required to constitute the act of the Board of Directors.

Qualifications of Directors.

No more than three (3) directors may be non-inside directors, and the balance must be inside directors, as defined in this subparagraph (A)(2).

An "inside director" is a director who is either a current inside director or a former inside director, as each of such terms is defined in this subparagraph (A)(2).



(c)

A "current inside director" is a director who (i) is a current Common stockholder of the Corporation; (ii) is currently an officer of either (A) the Corporation or (B) a Subsidiary which is engaged primarily in the construction, mining or materials businesses; and (iii) was continuously employed by the Corporation, its predecessor, former parent corporation or such a Subsidiary for at least six (6) years before becoming a director.



(d)

If a current inside director ceases to be a current inside director, such director may continue to serve as a director so long as there is a sufficient number of other inside directors so that the limitation on non-inside directors required by subparagraph (A)(2)(a) is satisfied. However, if as a result of the change in such director's status such non-inside director limitation would be exceeded, then such director shall automatically be deemed to have resigned as and shall cease to be a director. The remaining directors shall thereupon act promptly to fill the vacancy created by such resignation. Such a vacancy may be filled with a former inside director, as defined in subparagraph (A)(2)(e) below. If the director whose resignation created such vacancy qualifies as a former inside director pursuant to subparagraph (A)(2)(e), such director may be appointed to fill such vacancy.



(e)

A "former inside director" is a person who: (i) was at one time a current inside director; (ii) served as an inside director for at least eight (8) years; and (iii) is declared to be a former inside director by a majority vote of the directors holding office at the time of such declaration.

In nominating such election slates, the directors shall give due consideration to selecting nominees from each of the principal business segments represented by the activities of the Corporation and its Subsidiaries.



(B)

Cumulative Voting. At any election for directors every holder of Common Stock entitled to vote at such election shall have the right to vote, in person or by proxy, the number of shares owned by him for as many persons as there are directors to be elected and for whose election he has a right to vote, or to cumulate his votes by giving one candidate as many votes as the number of such directors multiplied by the number of his shares shall equal, or by distributing such votes on the same principle among any number of such candidates.



(C)

Officers. The Corporation shall have such officers as the by-laws may provide, except, however, that the Corporation shall have an officer or officers who shall be empowered to sign instruments and stock certificates of the Corporation and shall have an officer who shall have the duty to record the proceedings of stockholders' meetings and meetings of the Board of Directors. Officers shall be chosen in such manner and shall hold their offices for such terms as the by-laws may prescribe or as shall be determined by the Board of Directors.

(b)

Upon the termination of the employment of any Employee with the Corporation for any reason other than death, the Employee or his authorized transferee shall sell and deliver the Common Stock held by such Employee or his authorized transferee to the Corporation within ten (10) days after the date of a written notice from the Corporation to sell and deliver such stock (a "Repurchase Notice").

(d)

Ownership of Excessive Amount. Upon a determination by the Board of Directors that the amount of Common Stock held by an Employee and/or his authorized transferee is excessive in view of the Corporation's policy that the level of an Employee's stock ownership should reflect certain factors, including but not limited to (i) the relative contribution of that Employee to the economic performance of the Corporation, (ii) the effort being put forth by such Employee, and/or (iii) the level of responsibility of such Employee, the Corporation shall have the option to purchase from such Employee and/or his authorized transferee an amount of Common Stock sufficient to decrease the amount of such stock owned by such Employee or his authorized transferee to an amount that the Board of Directors, in its sole discretion, believes is appropriate. In the event that the Corporation elects to exercise this option, it shall give the Employee and/or his authorized transferee written notice to that effect and the Employee and/or his authorized transferee shall sell and deliver the amount of stock specified in such notice to the Corporation within ten (10) days after the date of the notice, with payment to be made for such stock within sixty (60) days after the date of said notice, without interest.



(e)

Pledges. Notwithstanding anything contained in subparagraphs (D)(1) and (D)(3) to the contrary, an Employee may pledge Common Stock for loans in connection with the ownership of the Corporations stock. In addition, notwithstanding anything contained in subparagraphs (D)(1) and (D)(3) to the contrary, Qualified Financial Institutions to which such Common Stock has been pledged shall be permitted to own such Common Stock upon foreclosure of such Common Stock in accordance with the terms of any agreement evidencing such pledge; provided that said Qualified Financial Institution shall not be permitted to transfer, assign, pledge, hypothecate, or otherwise dispose of such Common Stock except in a sale to the Corporation in accordance with the provisions of subparagraph (D)(3)(a) above; and provided further that said Qualified Financial Institution shall sell and deliver such Common Stock to the Corporation no later than the date which is ten (10) days after the date a written notice from the Corporation to sell and deliver such Common Stock is delivered to such Qualified Financial Institution. The purchase price for the Common Stock payable to a Qualified Financial Institution shall not be reduced by any amount owed to the Corporation or any Subsidiary by the Employee who pledged the Common Stock to the Qualified Financial Institution. Subject to the provisions of subparagraph (D)(8), payment of the purchase price shall be made by the Corporation within sixty (60) days of the date of receipt of certificates evidencing such Common Stock, without interest. In the event a Qualified Financial Institution fails to deliver stock certificates within the specified time period, the Corporations Secretary shall cancel each certificate on the books of the Corporation and such shares of Common Stock shall be deemed no longer outstanding. The Qualified Financial Institution shall thereafter have no further interest as a stockholder of the Corporation with respect to such shares of Common Stock except the right to receive the purchase price therefor. Notwithstanding anything contained in Certificate to the contrary, except as may otherwise be provided by statute, no shares of Common Stock owned by a Qualified Financial Institution shall have any voting rights of any kind. For purposes of this subparagraph (D)(3)(e), "Qualified Financial Institution" shall mean any bank, banking association, trust company, savings bank, credit union, savings and loan association or other financial institution which is engaged in the business of banking or making commercial or consumer loans, or any subsidiary or affiliate of any such entity.



(f)

Authorized Transferee. For purposes of this subparagraph (D)(3), the term "authorized transferee" shall mean any stockholder permitted to own stock of the Corporation pursuant to paragraph (D)(1) above.



(g)

Failures to Meet Time Limits. No failure by the Corporation, a stockholder, an authorized transferee, or the estate, successor, or personal representative of a stockholder to take any action within any time period prescribed by this subparagraph (D)(3) shall render the Common Stock of the Corporation transferable other than in conformance with the provisions of this subparagraph (D)(3) or preclude the Corporation from exercising its right to purchase any such stock.



(4)

Stock Price. The Corporation shall purchase or sell any share of Common Stock for a price equal to the Common Share Price. The consideration paid for such Common Stock shall be in cash or such other form as mutually agreed upon by the Corporation and the Common stockholder.



(5)

Limitations On Amount of Ownership. No more than ten (10%) percent of the shares of the Common Stock issued and outstanding shall at any time be owned of record, or voted, by or for the account of any one Employee as hereinbefore described. For purposes of calculation of said ten (10%) percent limitations Common Stock of the Corporation owned by an Employee's spouse, children, grandchildren, parents, grandparents and spouses of such persons (collectively, an Employee's "family members"), fiduciaries for the benefit of an Employee or his family members, fiduciaries for charities designated by an Employee or his family members, and any entity which an Employee or his family members have created or control, directly or indirectly, or in which an Employee or his family members have a beneficial or reversionary interest, shall be counted as being owned by the Employee. All calculations regarding the ten (10%) percent limitation (including both the numerator and denominator of the calculations) shall be on a fully diluted basis (i.e., all stock that in the future will be issued upon the conversion of any then-issued and outstanding Convertible Debentures of the Corporation shall be included in the calculations). The ten (10%) percent limitations shall be calculated as of the 1st day of January of each year, and any stockholder who owns more Common Stock than the ten (10%) percent limitation permits shall be so notified by the Corporation and shall, at the stockholder's option, be permitted to hold the excess stock until the next succeeding January 1, and on or before said January 1, the stockholder shall take the action described in subparagraph (D)(6) below.



(6)

Sales of Excess Stock. In the event that any stockholder through his own action or the action of others becomes an owner of more than ten (10%) percent, as defined in subparagraph (D)(5) above, of the Common Stock, he shall offer to the Corporation, and the Corporation shall purchase within sixty (60) days of such offer, at the price defined in subparagraph (D)(4) above, such amount of his stock that is in excess of said ten (10%) percent limitation. In the event that a stockholder shall fail to offer such stock to the Corporation within the period described in subparagraph (D)(5) above, the Corporation shall, within sixty (60) days following the end of such period, purchase such excess stock holdings.



(7)

Termination of Certain Owners. Any stockholder-Employee of the Corporation who owns two (2%) percent or more of the Common Stock issued and outstanding shall not be terminated from employment of the Corporation except by an affirmative vote of two-thirds of the whole Board of Directors. The Board of Directors shall have the right to reduce said two (2%) percent requirement in the by-laws of the Corporation to a lower percentage requirement by an affirmative vote of two-thirds of the whole Board of Directors. For purposes of calculation of this percentage requirement, the attribution rules specified in paragraph (D)(5) above regarding the ten (10%) percent limitation on ownership shall apply.



(8)

Suspension of Repurchase Duties. Notwithstanding anything in this ARTICLE SIXTH to the contrary, in the event that the Board of Directors determines that the Formula Value to be determined at the end of the fiscal year during which such determination is made is likely to be less than (i) the Formula Value determined at the end of the prior fiscal year less (ii) the aggregate amount of dividends declared on the Common Stock since the end of the prior fiscal year, the Board may suspend the Corporation's duty to repurchase shares of Common Stock in accordance with this paragraph (D)(8). Any such suspension shall not extend for a period longer than three hundred sixty-five (365) days from the date of the Boards declaration of suspension. During any such suspension period, the Corporation shall not repurchase any shares of Common Stock tendered or required to be tendered for repurchase pursuant to the second sentence of subparagraph (D)(3)(a). During any such suspension period, the Corporation shall continue to repurchase Common Stock tendered to the Corporation pursuant to any other provision of this Certificate of Incorporation, but (a) payment for such repurchases shall not be required until sixty (60) days after the end of the suspension period, (b) such payment shall be made without interest, and (c) the repurchase price shall be the Common Share Price determined as of (i) the end of the prior fiscal year, in the case of a suspension period that ends before July 1 of the fiscal year, (provided that such computation of the Share Price shall be reduced by the amount of dividends per share declared on the Common Stock since the end of the prior fiscal year), or (ii) in the case of a suspension period that ends after June 30 of a fiscal year, the end of the fiscal year during which the suspension period ends.



(E)

Payments Where Stock Price Not Yet Computed. If the price at which the Corporation is to purchase stock pursuant to any provision in this Certificate of Incorporation has not been computed within the time period prescribed for payment for such stock because the preparation of the audited Consolidated Financial Statements of the Corporation and Subsidiaries has not yet been completed, the Corporation shall, within the time period prescribed for payment for such stock, make an initial payment in an amount equal to the price that would have been paid for such stock if it had been purchased by the Corporation during the next preceding fiscal year. The balance shall be paid within ten (10) days after the date on which the price at which the Corporation is to purchase such stock has been computed. In the event that the price at which the Corporation is to purchase such stock is less than the amount paid by the Corporation, in the "initial payment" provided for in this paragraph (E), the Corporation shall be entitled to recover the difference between the two amounts. Such difference shall be paid by the person or entity to whom the Corporation made the "initial payment" within ten (10) days of the date of a written notice from the Corporation to pay such amount, without interest.



(F)

Ratification By Stockholders. Any contract, transaction or act of the Corporation or of the directors, which shall be ratified by a majority of a quorum of the stockholders then entitled to vote at any annual meeting or at any special meeting called for such purpose, shall, so far as permitted by law and by this Certificate of Incorporation, be as valid and as binding as though ratified by every stockholder entitled to vote at such meeting.



(G)

Meetings, Offices, and Books Outside State of Delaware. The stockholders and the Board of Directors may hold their meetings and the Corporation may have one or more offices outside of the State of Delaware, and subject to the provisions of the laws of said state, may keep the books of the Corporation outside of said state and at such places as may be from time to time designated by the Board of Directors.



(H)

Removal of Directors. At any meeting of the holders of the Common Stock called for the purpose, any one or more of the directors may, by a majority vote of the holders of the Common Stock at the time, be removed from office, with or without cause, and another director or other directors be elected by such majority vote of said holders of the Common Stock in the place or places of the person or persons so removed, to serve for the remainder of his or their term or terms, as the case may be; provided, however, that if less than all the directors are to be removed, no individual director shall be removed without cause when the votes cast against his removal would be sufficient to elect him if then cumulatively voted at an annual election of all the directors.



(I)

By-Law Provisions for Conduct of Business. The Corporation may in its by-laws make any other provisions or requirements for the conduct of the business of the Corporation, provided the same be not inconsistent with the provisions of this Certificate of Incorporation, or contrary to the laws of the State of Delaware. The by-laws may be amended by affirmative vote of two-thirds of the whole Board of Directors or by affirmative vote of the holders of two-thirds of the Common Stock issued and outstanding.



(J)

Requirements of Votes Greater Than Required By-Law. Whenever this Certificate of Incorporation contains provisions requiring for any corporate action the vote of a larger portion of the stock or a larger portion of the directors than is required by the General Corporation Law of the State of Delaware, the provisions of this Certificate of Incorporation shall govern and control.



(K)

Amendments of Certificate. Subject to any limitations herein contained, the Corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, or in any amendment thereto by an affirmative vote of the holders of two-thirds of the Common Stock issued and outstanding, and all rights conferred upon stockholders in said Certificate of Incorporation or any amendment thereto, are granted subject to this reservation; provided, however, that the provisions of this Certificate of Incorporation requiring for action by the stockholders a vote greater than such two-thirds vote shall not be amended except by such greater vote; and provided further that this Paragraph (K) shall not be amended except by an affirmative vote of the holders of four-fifths of the Common Stock issued and outstanding.



ARTICLE SEVENTH



LIMITATION OF LIABILITY



A director of this Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the Delaware General Corporation Law, or (iv) for any transaction from which the director derived an improper personal benefit. If the Delaware General Corporation Law is amended after approval by the stockholders of this ARTICLE SEVENTH to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law as so amended. Any repeal or modification of this paragraph by the stockholders of the Corporation shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification.
