                           LEVERAGED STOCK OPTION PLAN



ARTICLE I.  PURPOSE. DEFINITIONS.

        Section 1.1

                      The purpose of this Plan is to provide executive officers
        of the Company an incentive to promote the maximization of shareholder
        value over the long term. In order to help promote a culture of
        ownership among the Company's executive officers and to align management
        incentives with shareholder interests, incentive compensation will be
        tied to Economic Value Added ("EVA") as delineated in the C.H. Heist
        Corp. EVA Incentive Remuneration Plan (the "EVA Plan"). This Plan will
        reward significantly the achievement of increases in economic value, and
        penalize any decreases in economic value, and will operate over a
        long-term horizon. The Plan also provides a means through which the
        Company can attract and retain executive officers of merit.

ARTICLE III.  STOCK SUBJECT TO PLAN.

        Section 3.1

                      The total number of shares of Stock reserved and available
        for issuance pursuant to the exercise of Stock Options granted under the
        Plan shall be 375,000 shares. Such shares may consist, in whole or in
        part, of authorized and unissued shares or treasury shares.

        Section 3.2

                      If any shares of Stock that have been optioned cease to be
        subject to a Stock Option, or if any Stock Option terminates other than
        upon exercise, such shares shall again be available for issuance in
        connection with grants under the Plan.

        Section 3.3

                      In the event of any merger, reorganization, consolidation,
        recapitalization, stock dividend, stock split or other change in
        corporate structure which affects the Stock, such substitution or
        adjustments shall be made in the aggregate number of shares reserved for
        issuance under the Plan, and in the number and exercise price of shares
        subject to outstanding Stock Options granted under the Plan, as may be
        determined to be appropriate by the Board, in its sole discretion.

ARTICLE V.  STOCK OPTIONS.

        Section 5.1

                      Stock Options shall be granted in connection with bonus
        awards under the EVA Plan. An executive officer who participates in this
        Plan will receive a grant of Options hereunder only if he receives a
        bonus under the EVA Plan. Generally, under the EVA Plan if certain
        performance targets are achieved, then a bonus is paid to the
        participants. Most participants receive 100% of the bonus. Executive
        officers who participate in this Plan will receive a percentage
        (currently 90%, but subject to change by the Committee) of the cash
        bonus. The remaining portion (currently 10%, but subject to change by
        the Committee) of the bonus is used in a formula in this Plan to
        determine the number of shares subject to the Option that will be
        granted to the participant hereunder as further provided in Section
        5.3(c).

        Section 5.2

                      All Stock Options shall be evidenced by option agreements,
        the terms and provisions of which are determined by the Committee. Each
        option agreement shall specify that it is an agreement which provides
        for Non-Qualified Stock Options.

        Section 5.3

                      Options granted under the Plan shall be subject to the
        following terms and conditions, and such additional terms and conditions
        as the Committee deems appropriate:

        a.     Exercise Price. The exercise price per share of Stock purchasable
               under a Stock Option shall be equal to the Fair Market Value of
               the Stock, reduced by the initial exercise price percentage
               discount, increased annually by a fixed percentage, initially 8%
               (but subject to change by the Committee).

        b.     Initial Exercise Price Percentage Discount. The initial exercise
               price percentage discount is a fixed percentage that is used to
               reduce the initial exercise price to purchase Stock pursuant to
               Options granted hereunder. The initial exercise price percentage
               discount is 10% (but subject to change by the Committee).

        c.     Number of Shares Covered by Option. The number of shares of Stock
               subject to an Option granted to a participant hereunder will
               equal the amount of the participant's bonus which is not paid
               under the EVA

                                       -5-

   6



               Plan divided by the Initial Exercise Price Percentage Discount
               times the Fair Market Value of the Stock. The amount of the
               participant's unpaid bonus under the EVA Plan is not paid in
               consideration for the Option; it is merely a figure utilized in
               the formula to determine the number of shares covered by an
               Option granted under the Plan.

        d.     Option Term. Each Stock Option shall be exercisable during the
               ten (10) year period following the date such Option was granted.

        e.     Vesting. Except as otherwise provided herein, all Options granted
               under the Plan shall vest three years after the date such Option
               was granted.

        f.     Exercisability. Vested Stock Options shall be exercisable at such
               time or times and subject to such terms and conditions as the
               Committee shall determine.

        g.     Method of Exercise. Subject to the provisions of this Article V,
               vested Stock Options may be exercised, in whole or in part, at
               any time during the option term upon delivery of irrevocable
               written notice of exercise to the Secretary of the Company
               specifying the number of shares to be purchased and whether
               payment of the exercise price is to be made pursuant to clause
               (i) or (ii). Except as otherwise provided below, such notice
               shall be accompanied by payment in full of the purchase price by
               certified or bank check, or such other instrument as the Company
               may accept. The Committee may, in its sole discretion, allow
               payment in full or in part to be made in the form of unrestricted
               Stock already owned by the Optionee. The date on which such
               notice is received by the Secretary shall be the date of exercise
               of the Option, provided that: (i) full payment as hereinbefore
               provided accompanies the notice; or (ii) within five business
               days of the delivery of such notice, the funds to pay for the
               exercise of the Option are delivered to the Company by a broker
               acting on behalf of the Optionee either in connection with the
               sale of the shares of Stock underlying the Option or in
               connection with the making of a margin loan to the Optionee to
               enable payment of the exercise price of the Option. In connection
               with clause (ii) above, the Company will provide a copy of the
               notice of the exercise to the aforesaid broker (which must be
               identified by the Optionee in the notice of exercise) upon
               receipt by the Secretary of such notice and will deliver to such
               broker, within five business days of the delivery of such notice
               to the Company, a certificate or certificates (as requested by
               the broker) representing the number of shares of Stock

                                       -6-

   7



               underlying the Option that have been sold by such broker for the
               Optionee.

                             No shares of Stock shall be issued until full
               payment therefor has been made. An Optionee shall have all of the
               rights of a shareholder of the Company, including the right to
               vote the Stock and the right to receive dividends with respect to
               shares subject to the Stock Option, when the Optionee has given
               written notice of exercise, has paid in full for such Stock and,
               if requested, has given the representation described in Section
               9.1 hereof.

        h.     Non-Transferability of Options. No Stock Option shall be
               transferable by the Optionee other than by will or by the laws of
               descent and distribution, and all Stock Options shall be
               exercisable, during the Optionee's lifetime, only by the Optionee
               or by the guardian or legal representative of the Optionee. For
               purposes of this provision, the terms "holder" and "Optionee"
               shall include the guardian and legal representative of the
               Optionee named in the option agreement, together with any
               individual to whom an Option is transferred by will or the laws
               of descent and distribution.

        i.     Cashing Out of Option. On receipt of written notice to exercise,
               the Committee may elect to cash out all or part of any Stock
               Option to be exercised by paying the Optionee an amount, in cash
               or Stock, equal to the excess of the Fair Market Value of the
               Stock over the exercise price (the "spread value") on the
               effective date of such cash out. Cash outs relating to Options
               held by Optionees who are actually or potentially subject to
               Section 16(b) of the Exchange Act shall comply with the "window
               period" provisions of Rule 16b-3, to the extent applicable.

        j.     Termination by Death. If an Optionee's employment terminates by
               reason of death, the spread value, as defined in Section 5.3(i),
               of any vested Stock Option held by such Optionee will be paid in
               cash to said Optionee's estate or designated beneficiary.

        k.     Termination by Reason of Disability or Retirement. If an
               Optionee's employment terminates by reason of Disability or
               Retirement, any vested Stock Option held by such Optionee may
               thereafter be exercised by such Optionee in accordance with its
               terms; however, if an Optionee dies after such Disability or
               Retirement, any unexercised vested Stock Option held by such
               Optionee shall be treated pursuant to Section 5.3(j) above.


                                       -7-

   8



        l.     Other Termination. Unless otherwise determined by the Committee,
               if an Optionee's employment terminates for any reason other than
               Death, Disability or Retirement, the Stock Options held by such
               Optionee, whether or not vested, shall thereupon terminate.
               Notwithstanding the preceding sentence: (i) an Optionee will
               receive in cash the spread value, as defined in Section 5.3(i),
               of any such vested Stock Options held by the Optionee if such
               Optionee is involuntarily terminated by the Company or a
               subsidiary thereof without cause; and (ii) if such Optionee
               voluntarily terminates his employment, he will receive in cash
               the lesser of the spread value of his vested options or the
               amount equal to the product of (i) the number of shares of Stock
               subject to the Option and (ii) the Initial Exercise Price
               Percentage Discount at the time of the grant multiplied by the
               Fair Market Value of the Stock at the time of such grant used to
               determine the initial exercise price of the Option.

        m.     Change-in-Control. Notwithstanding the foregoing, upon a
               Change-in-Control (as defined in Section 6.2), all Options held
               by each Optionee shall immediately vest and the excess of the
               Change-in-Control Price over the exercise price of each Stock
               Option held by each Optionee shall be paid in cash to said
               Optionee within 30 days of the date such Change-in-Control is
               determined to have occurred.


ARTICLE VI.  CHANGE-IN-CONTROL PROVISIONS.

        Section 6.1

                             Impact of Event. Notwithstanding any other
               provision of the Plan to the contrary, in the event of a
               Change-in-Control (as defined in Section 6.2), any Stock Options
               outstanding as of the date such Change-in-Control is determined
               to have occurred, which have not then become exercisable or
               vested, shall become fully exercisable and vested.

        Section 6.2

                             Definition of Change-in-Control. For purposes of
               the Plan, a "Change-in-Control" shall mean an event that, in the
               judgment of the Board and on the advice of the Company's counsel,
               is required to be reported in response to item 1 of Form 8-K or
               any successor form thereto promulgated under the Exchange Act.

        Section 6.3

                             Change-in-Control Price. For purposes of the Plan,
               "Change-in-Control Price" means the highest price per share paid
               or offered in any bona fide transaction (via tender offer, merger
               or on a stock exchange or otherwise) related to a
               Change-in-Control of the Company at any time during the preceding
               60-day period as determined by the Committee.


ARTICLE VII.  AMENDMENTS AND TERMINATION.

        Section 7.1

                      The Board by written resolution may amend, alter, or
        discontinue the Plan, subject to shareholder approval as and where
        required by law; however, no amendment, alteration or discontinuation
        shall be made which would impair the rights of an Optionee under a Stock
        Option theretofore granted without such Optionee's consent.

                      Subject to the above provisions, the Board shall have the
        authority to amend the Plan to take into account changes in the law and
        tax and accounting rules, as well as other developments.


ARTICLE VIII.  UNFUNDED STATUS OF PLAN.

                      The Plan presently is an "unfunded" plan for incentive and
        deferred compensation. However, the Committee may authorize the creation
        of trusts or other arrangements to meet the obligations created under
        the Plan to deliver Stock or make payments, so long as such trusts or
        other arrangements remain consistent with, and do not alter, the Plan's

ARTICLE IX.  GENERAL PROVISIONS.

        Section 9.1

                      The Committee may require each individual purchasing
        shares pursuant to a Stock Option to represent to the Company in writing
        that such individual is acquiring the shares without a view to the
        disposition thereof. The certificates for such shares may include any
        legend which the Committee deems appropriate to reflect any restrictions
        on transfer.

        Section 9.2

                      All certificates for shares of Stock or other securities
        delivered under the Plan shall be subject to such stock transfer orders
        and other restrictions as the Committee may deem advisable under the
        rules, regulations and other requirements of the Commission, any stock
        exchange upon which the Stock is then listed, and any applicable federal
        or state securities law, and the Committee may cause a legend or legends
        to be put on any such certificates to make appropriate reference to such
        restrictions.

        Section 9.3

                      Nothing contained in this Plan shall prevent the Company
        or any subsidiary thereof from adopting other or additional compensation
        arrangements for its employees.

        Section 9.4

                      The adoption of the Plan shall not confer upon any
        employee any right to continued employment, nor shall it interfere in
        any way with the right of the Company or any subsidiary thereof to
        terminate the employment of any employee at any time.

        Section 9.5

                      No later than the date as of which an amount first becomes
        includable in the gross income of an Optionee (or other holder of an
        Option, as applicable) by reason of the exercise or other negotiation or
        disposition of an Option granted under the Plan, such Optionee or other
        holder shall pay to the Company, or make arrangements satisfactory to
        the Company regarding the payment of, any federal, state, local or
        foreign taxes of any kind required by law to be withheld with respect to
        such gross income. In the sole discretion of the Company, any and all
        such withholding obligations may be settled with Stock, including the
        Stock which gives rise to the withholding requirement. The obligations
        of the Company under the Plan shall be conditioned on such payment or
        arrangements, and the Company and its subsidiaries shall, to the extent
        permitted by law, have the right to deduct and withhold any such taxes
        from any payment or Stock otherwise due to be paid or transferred.

        Section 9.6

                      At the time of grant, the Committee may provide in
        connection with any grant made under this Plan that the shares of Stock
        received as a result of such grant shall be subject to a right of first
        refusal in favor of the Company, wherein such Optionee (or such other
        holder) shall be

                                      -10-

        required to offer to the Company any Stock that such Optionee or other
        holder wishes to sell at its then fair market value, subject to such
        other terms and conditions as the Committee may specify at the time of
        grant.

        Section 9.7

                      The Committee shall establish such procedures as it deems
        appropriate for an Optionee to designate a beneficiary to whom any
        amounts or shares of Stock, payable or transferable in the event of an
        Optionee's death, are to be paid or transferred.
