         securities, cash or other property, each Debenture shall thereafter be
         convertible into the kind and amount of securities, cash and other
         property receivable upon the consummation of such Transaction by a
         holder of that number of shares of Common Stock into which a Debenture
         was convertible immediately prior to such Transaction, or (ii) in the
         case of a Transaction involving a Common Stock Fundamental Change,
         common stock, each Debenture shall thereafter be convertible (in the
         manner described herein) into common stock of the kind received by
         holders of Common Stock (but in each case after giving effect to any
         adjustment discussed in paragraphs (b) and (c) relating to a
         Fundamental Change if such Transaction constitutes a Fundamental
         Change). The holders of Debentures or Preferred Securities will have no
         voting rights with respect to any Transaction."

         to the date 60 days (or the first business day thereafter if the 60th
         day is not a business day) following the date of the receipt by the
         Company of the Executive's notice described herein; PROVIDED, HOWEVER,
         that if such payment is being made on or after the first day of the
         seventh month of any fiscal year, then such payment shall be made on or
         prior to the date that is 60 days (or the first business day thereafter
         if the 60th day is not a business day) following the date of the
         determination of Fair Market Value in a manner consistent with the
         provisions of the Management Stockholders' Agreement.

             (iii) If the Executive holds Exercisable Options as of the date he
         notifies the Company of the exercise of the Executive Put pursuant to
         Section 4(k)(ii) and together with such notice notifies the Company
         that he desires to exercise a specified portion of such Exercisable
         Options (the "Specified Options"), the Company shall, or shall cause an
         affiliate of the Company to, lend to the Executive within 30 days after
         the Company's receipt of such notice from the Executive an amount equal
         to the aggregate exercise price payable with respect to the Specified
         Options and the aggregate federal, state and local income tax
         liability, including any alternative minimum tax obligations, that will
         actually be incurred by the Executive as a result of his exercise of
         the Specified Options in accordance with such notice. Any such loan
         pursuant to this Section 4(k)(iii) shall be pursuant to the terms of a
         secured, recourse promissory note or notes which (i) shall be payable
         in full no later than the earliest of (A) the date on which the
         Executive receives any payment from the Company for the repurchase of
         the shares acquired upon exercise of the Specified Options, (B) the
         date on which the Executive transfers any such shares and (C) the first
         date following the expiration of the Put Period, (ii) shall bear
         interest at the applicable federal mid-term rate determined pursuant to
         Section 1274(d) of the Internal Revenue Code of 1986, as amended, (iii)
         shall provide that any interest due on such loan shall be converted
         into principal and shall not be payable currently as it is accrued, but
         rather shall be payable when the principal amount is due and (iv) shall
         be in a form acceptable to the Company's (or its affiliate's) lenders
         under the terms of the Financing Documents. The parties hereto agree
         that to the extent any of the foregoing provisions of this Section
         4(k)(iii) result in adverse accounting consequences to the Company,
         such provisions shall be modified in a manner mutually acceptable to
         the parties hereto.

5.       TERMINATION.

         (a) The Executive's employment hereunder may be terminated by the
Company or the Executive, as applicable, without any breach of this Agreement

             (i)   DEATH. The Executive's employment hereunder shall terminate
         upon his death.

             (ii)  DISABILITY. If the Company determines in good faith that the
         Executive has incurred a Disability, the Company may give the Executive
         written notice of its intention to terminate the Executive's
         employment. In such event, the Executive's employment with the Company
         shall terminate effective on the 30th day after receipt of such Notice
         of Termination by the Executive, provided that within such 30 day
         period the Executive shall not have returned to full-time performance
         of his duties.

             (iii) TERMINATION FOR CAUSE. The Company may terminate the
         Executive's employment hereunder for Cause.

         anniversary of the Effective Date.

         (b) NOTICE OF TERMINATION. Any termination of the Executive's
employment by the Company or by the Executive under this Section 5 (other than
termination pursuant to subsection (a)(i)) shall be communicated by a written
notice from the Board or the Executive to the other, indicating the specific
termination provision in this Agreement relied upon, setting forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Executive's employment under the provision so indicated, and specifying a
Date of Termination (a "Notice of Termination"). For purposes of this Agreement,
the "Date of Termination" shall be (i) with respect to any termination by reason
of the Executive's Disability, 30 days following the receipt of the notice
described in Section 5(a)(ii); (ii) with respect to the Executive's termination
for Cause, the date of the Notice of Termination, and (iii) with respect to the

and all other compensation and perquisites referenced in Section 4 through the
Date of Termination.

6.       SEVERANCE PAYMENTS.

         (a) TERMINATION FOR ANY REASON. In the event the Executive's employment
with the Company is terminated for any reason, the Company shall pay the
Executive (or his beneficiary in the event of his death) any unpaid Annual Base
Salary that has accrued as of the Date of Termination, any unreimbursed expenses
due to the Executive and an amount for accrued but unused sick days and vacation
days. The Executive shall also be entitled to accrued, vested benefits under the
Company's benefit plans and programs as provided therein. The Executive shall be
entitled to the additional payments and benefits described below only as set
forth herein.

         (b) TERMINATION WITHOUT CAUSE, RESIGNATION FOR GOOD REASON OR
TERMINATION BY REASON OF DEATH OR DISABILITY. In the event of the Executive's
Termination without Cause (pursuant to Section 5(a)(v)), Resignation for Good
Reason (pursuant to Section 5(a)(iv)) or termination by reason of Death or
Disability (pursuant to Section 5(a)(i) or (ii), respectively), the Company
shall pay to the Executive the amounts described in subsection (a), and:

             (i) subject to the Executive's compliance with Sections 8 and 9,
         pay to the Executive, for the twenty-four month period following the
         Date of Termination, in accordance with its regular payroll practice,
         his Annual Base Salary as in effect on the Date of Termination; and

             (ii) for the year in which the termination occurs, pay to the
         Executive a pro-rated amount of bonus based on the Company's executive
         annual bonus plan as in effect at that time; and

             (iii) continue for one year the Executive's coverage under the
         Company medical and dental plans and programs in which the Executive
         was entitled to participate immediately prior to the Date of
         Termination (or, if the Company amends, replaces or terminates any such
         plan or program following such Date of Termination, the Company medical
         and dental plans provided to employees similarly situated to
         Executive), as if the Executive were an active employee during such
         time, subject to standard employee contributions by the Executive as
         are required under such plans, and further subject to the Executive's
         election of "COBRA" continuation coverage during such period. All
         post-employment coverage under such plans shall be co-extensive with
         COBRA continuation coverage required by federal (and where applicable
         by state) law, and shall cease if the Executive becomes eligible for
         coverage under another employer's plans.

                                       10
<PAGE>   11

7.       OTHER TERMINATION PROVISIONS.

         Notwithstanding any provision of this Agreement or the Management
Stockholders' Agreement to the contrary, in the event that as a consequence of a
termination of the Executive's employment for any reason, the Executive is
compelled to exercise any Options in order to prevent such Options from expiring
in accordance with their terms and the Company is unable to repurchase the
Executive's stock at such time, the Company shall either (i) provide the
Executive with an interest-free recourse loan equal to the actual aggregate
federal, state and local income tax liability (including alternative minimum tax
obligations) incurred as a consequence of the Option exercise, which loan shall
(A) be secured by a pledge of the shares acquired upon exercise of such Options,
(B) be payable in full, with respect to each Option (or portion) so exercised,
upon the earliest of (I) the tenth anniversary of the date of grant of such
Option, (II) five days after the date on which the Executive sells, transfers or
otherwise disposes or conveys for consideration the shares acquired upon
exercise of such Option, and (III) the date specified in the Management
Stockholders' Agreement for the expiration of certain provisions thereof, (ii)
permit the Executive to extend the post-termination exercise period of such
Options (but not beyond the tenth anniversary of the date of Option grant) until
such time as the Company is able to repurchase the underlying shares of Common
Stock, or (iii) devise such other method that is reasonably acceptable to the
Executive so as to prevent the Executive from incurring tax liability upon
Option exercise at a time when he is not able to receive payment from the
Company (or a third party) for the shares acquired upon such exercise.

8.       COMPETITION.

         (a) The Executive shall not engage in any Prohibited Competition (as
defined below in Section 8(b)) at any time during the Term or the Non-Executive
Term, if any, and for a period of two years after the later to end of the Term
and the Non-Executive Term.

         (b) For purposes of this Agreement, the Executive shall be considered
to engage in prohibited competition ("Prohibited Competition") if the Executive
shall: directly or indirectly, engage in or own, manage, join, operate or
control, or participate in the ownership, management, operation or control of,
or be connected as a director, officer, employee, partner, consultant or
otherwise with, or permit his name to be used by or in connection with, any
business or organization which produces, designs, conducts research on,
provides, sells, leases, distributes or markets accessories, chemicals, forming
and related products used in concrete and masonry construction (the "Business")
which, directly or indirectly, competes with the Business conducted by Company
and its subsidiaries in North America, South America and Europe, it being
understood that the foregoing shall not limit the Executive from making passive
investments of less than 5% of the outstanding equity securities in any entity
listed for trading on a national stock exchange or quoted on any recognized
automatic quotation system.

                                       11
<PAGE>   12

         (c) In the event any of the terms of this Section 8 shall be determined
by any court of competent jurisdiction to be unenforceable by reason of
extending for too great a period of time or over too great a geographical area
or by reason of being too extensive in any other respect, it will be interpreted
to extend only over the maximum period of time for which it may be enforceable,
and/or over the maximum geographical area as to which it may be enforceable
and/or to the maximum extent in all other respects as to which it may be
enforceable, all as determined by such court in such action.

9.       NONDISCLOSURE OF PROPRIETARY INFORMATION.

         (a) Except as required in the faithful performance of the Executive's
duties hereunder or pursuant to subsection (c), the Executive shall, in
perpetuity, maintain in confidence and shall not directly, indirectly or
otherwise, use, disseminate, disclose or publish, or use for his benefit or the
benefit of any person, firm, corporation or other entity any confidential or
proprietary information or trade secrets, and any other information that would
be protected under the Uniform Trade Secrets Act in Ohio, of or relating to the
Company, including, without limitation, information with respect to the
Company's operations, processes, products, inventions, business practices,
business strategy, business development, finances, principals, vendors,
distributors, suppliers, customers, potential customers, manufacturing methods,
sales methods, marketing methods, costs, prices, contractual relationships,
information systems, regulatory status, compensation paid to employees or other
terms of employment, or deliver to any person, firm, corporation or other entity
any document, record, notebook, computer program or similar repository of or
containing any such confidential or proprietary information or trade secrets.
The parties hereby stipulate and agree that as between them the foregoing
matters are important, material and confidential proprietary information and
trade secrets and affect the successful conduct of the businesses of the Company
(and any successor or assignee of the Company). The parties hereto agree that
"confidential or proprietary information" shall not include information that (i)
is a matter of public knowledge (other than by act of the Executive in violation
hereof); (ii) was provided to the Executive (without breach of any obligation of
confidence owed to the Company) by a third party which is not an affiliate of
the Company or (iii) is required to be disclosed by law or judicial or
administrative process.

         (b) Upon termination of the Executive's employment with Company for any
reason and upon the Company's request, the Executive will promptly deliver to
the Company all correspondence, drawings, manuals, letters, notes, notebooks,
reports, programs, plans, proposals, financial documents, or any other documents
concerning, without limitation, the Company's operations, processes, products,
inventions, business practices, business strategy, business development,
finances, principals, vendors, distributors, suppliers, customers, potential
customers, manufacturing methods, sales methods, marketing methods, costs,
prices, contractual relationships, information systems, regulatory status,
compensation paid to employees or other terms of employment and/or which contain
proprietary information or trade secrets.

                                       12
<PAGE>   13

         (c) The Executive may respond to a lawful and valid subpoena or other
legal process but shall give the Company the earliest possible notice thereof,
shall, as much in advance of the return date as possible, make available to the
Company and its counsel the documents and other information sought and shall
assist such counsel in resisting or otherwise responding to such process.

10.      INJUNCTIVE RELIEF.

         It is recognized and acknowledged by the Executive that a breach of the
covenants contained in Sections 8 and 9 will cause irreparable damage to the
Company and its goodwill, the exact amount of which will be difficult or
impossible to ascertain, and that the remedies at law for any such breach will
be inadequate. Accordingly, the Executive agrees that in the event of a breach
of any of the covenants contained in Sections 8 and 9, in addition to any other
remedy which may be available at law or in equity, the Company shall be entitled
to specific performance and injunctive relief.

11.      SURVIVAL.

         The expiration or termination of the Term shall not impair the rights
or obligations of any party hereto which shall have accrued hereunder prior to
such expiration.

12.      BINDING ON SUCCESSORS.

         This Agreement shall be binding upon and inure to the benefit of the
Company, the Executive and their respective successors, assigns, personnel and
legal representatives, executors, administrators, heirs, distributees, devisees,
and legatees, as applicable.

13.      GOVERNING LAW.

         This Agreement shall be governed, construed, interpreted and enforced
in accordance with the substantive laws of the State of Ohio.

14.      VALIDITY.

         The invalidity or unenforceability of any provision or provisions of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect.

15.      NOTICES.

         Any notice, request, claim, demand, document or other communication
hereunder to any party shall be effective upon receipt (or refusal of receipt)

16.      COUNTERPARTS.

         This Agreement may be executed in several counterparts, each of which
shall be deemed to be an original, but all of which together shall constitute
one and the same Agreement.

17.      ENTIRE AGREEMENT.

         The terms of this Agreement, together with the Management Stockholders'
Agreement, the Option Plan and the Option Agreements, are intended by the
parties to be the final expression of their agreement with respect to the
employment of the Executive by the Company and may not be contradicted by
evidence of any prior or contemporaneous agreement. The parties further intend
that this Agreement, and the aforementioned contemporaneous documents, shall
constitute the complete and exclusive statement of its terms and that no
extrinsic evidence whatsoever may be introduced in any judicial, administrative,
or other legal proceeding to vary the terms of this Agreement. Notwithstanding
any of the foregoing to the contrary, in the event of a conflict between the
terms of this Agreement and the Management Stockholders' Agreement, the terms of
this Agreement shall govern.

18.      AMENDMENTS; WAIVERS.

         This Agreement may not be modified, amended, or terminated except by an
instrument in writing, signed by the Executive and the Chairman of the
Compensation Committee. By an instrument in writing similarly executed, the
Executive or the Company may waive compliance by the other party or parties with
any provision of this Agreement that such other party was or is obligated to
comply with or perform; PROVIDED, HOWEVER, that such waiver shall not operate as
a waiver of, or estoppel with respect to, any other or subsequent failure. No
failure to exercise and no delay in exercising any right, remedy or power
hereunder shall preclude any other or further exercise of any other right,
remedy or power provided herein or by law or in equity.

19.      NO INCONSISTENT ACTIONS.

         The parties hereto shall not voluntarily undertake or fail to undertake
any action or course of action inconsistent with the provisions or essential
intent of this Agreement. Furthermore, it is the intent of the parties hereto to
act in a fair and reasonable manner with respect to the interpretation and
application of the provisions of this Agreement.

20.      ARBITRATION.

         Any dispute or controversy arising under or in connection with this
Agreement shall be settled exclusively by arbitration, conducted before a panel
of three arbitrators in Cleveland, Ohio, in accordance with the rules of the
American Arbitration Association then in effect. Judgment may be entered on the
arbitrator's award in any court having jurisdiction; PROVIDED, HOWEVER, that the
Company shall be entitled to seek a restraining order or injunction in any court

                                       15
<PAGE>   16

of competent jurisdiction to prevent any continuation of any violation of the
provisions of Section 8 or 9 of this Agreement and the Executive hereby consents
that such restraining order or injunction may be granted without the necessity
of the Company's posting any bond; and PROVIDED FURTHER, that the Executive
shall be entitled to seek specific performance of his right to be paid until the
Date of Termination during the pendency of any dispute or controversy arising
under or in connection with this Agreement. Each of the parties hereto shall
bear its share of the fees and expenses of any arbitration hereunder.

21.      INDEMNIFICATION AND INSURANCE; LEGAL EXPENSES.

         During the Term and so long as the Executive has not breached any of
his obligations set forth in Sections 8 and 9, the Company shall indemnify the
Executive to the fullest extent permitted by the laws of the State of Delaware,
as in effect at the time of the subject act or omission, and shall advance to
the Executive reasonable attorneys' fees and expenses as such fees and expenses
are incurred (subject to an undertaking from the Executive to repay such
advances if it shall be finally determined by a judicial decision which is not
subject to further appeal that the Executive was not entitled to the
reimbursement of such fees and expenses) and he shall be entitled to the
protection of any insurance policies the Company shall elect to maintain
generally for the benefit of its directors and officers ("Directors and Officers
Insurance") against all costs, charges and expenses incurred or sustained by him
in connection with any action, suit or proceeding to which he may be made a
party by reason of his being or having been a director, officer or employee of
the Company or any of its subsidiaries or his serving or having served any other
enterprise as a director, officer or employee at the request of the Company
(other than any dispute, claim or controversy arising under or relating to this
Agreement). The Company covenants to maintain during the Term for the benefit of
the Executive (in his capacity as an officer and director of the Company)
Directors and Officers Insurance providing customary benefits to the Executive.
