3.   Position and Duties. During the Employment Period, the Executive shall
     serve as the [TITLE] of the Company and shall have the normal duties,

          all reasonable expenses incurred by the Executive during the

          under this Agreement that are consistent with the Company's policies
          in effect from time to time with respect to travel, entertainment and
          other business expenses, subject to the Company's requirements
          applicable generally with respect to reporting and documentation of
          such expenses.

          plans (including supplements thereto), vacation, perquisites and other
          benefits, but excluding, except as hereinafter provided in Section 6,
          any severance pay program or policy of the Company) for which
          substantially all other similarly situated executives of the Company

          time by the Board or a committee of the Board.

     (e)  Indemnification. The Executive shall be eligible to enter into the

          the first to occur of any of the following events:

          (i)  the Executive's death;

          (ii) the Company's termination of the Executive's employment on

6.   Post-Employment Period Payments.

     (a)  At the end of the Employment Period for any reason, the Executive
          shall cease to have any rights to salary, bonus, expense
          reimbursements or other benefits, except that the Executive shall be
          entitled to receive: (i) as soon as practicable following the end of
          the Employment Period, any Base Salary which has accrued but is
          unpaid, any reimbursable expenses which have been incurred but are
          unpaid, and payment for any unexpired vacation days which have accrued
          under the Company's or a Subsidiary's vacation policy but are unused,
          as of the end of the Employment Period, (ii) any plan benefits which
          by their terms extend beyond termination of the Executive's employment
          (but only to the extent provided in any such benefit plan in which the
          Executive has participated as an employee of the Company or a
          Subsidiary and excluding, except as hereinafter provided in Section 6,
          any severance pay program or policy of the Company or a Subsidiary),
          (iii) payments or benefits payable pursuant to the terms of any annual
          and/or long-term incentive plan of the Company or a Subsidiary in
          accordance with the terms thereof, and (iv) any benefits to which the
          Executive is entitled under Part 6 of Subtitle B of Title I of the
          Employee Retirement Income Security Act of 1974, as amended ("COBRA").
          In addition, the Executive shall be entitled to the additional
          benefits and amounts described in the succeeding subsections of this
          Section 6, in the circumstances described in such subsections.

     (b)  If the Employment Period ends pursuant to Section 5 hereof on account
          of death, a Voluntary Termination, a Termination for Cause or a
          termination on account of the Executive's Disability, the Company
          shall make no further payments to the Executive except as contemplated
          in Section 6(a) above.

     (c)  If the Employment Period ends early pursuant to Section 5 on account
          of a Termination without Cause, the Executive shall be entitled to the
          payments contemplated in Section 6(a) above and as set forth below:

          (i)  Within ten (10) business days after the expiration of any
               revocation period relating to the Release Agreement described in
               Section 11 below, the Executive shall be entitled to a lump sum
               payment in an amount equal to two (2) times the sum of (A) Base
               Salary (at the highest rate in effect for any period within two
               years prior to the Termination Date), plus (B) annual bonus (in
               an amount equal to target annual bonus for the year in which the
               Termination Date occurs).

          (ii) Within ten (10) business days after the expiration of any
               revocation period relating to the Release Agreement described in
               Section 11 below, the Executive shall be entitled to a lump sum
               payment equal to the total cost (including both the Executive's
               and the Company's portion of such costs as paid while the
               Executive was employed) of continuing the medical, dental,
               vision, long-term disability and life insurance benefits
               (excluding benefits under the executive death benefit plan)
               substantially similar to those that the Executive was receiving
               or entitled to receive immediately

                                       3

<PAGE>

               prior to the Termination Date for a period of eighteen (18)
               months; provided, however, if any benefit described in this
               Section 6(c)(ii) is subject to tax, the Company will pay to the
               Executive an additional amount such that after payment by the
               Executive or the Executive's dependents or beneficiaries, as the
               case may be, of all taxes so imposed, the recipient retains an
               amount equal to such taxes.

          (iii) In addition to the retirement and other benefits to which the
               Executive is entitled under the Company's defined benefit
               retirement plans (including any supplemental plans) with respect
               to the Executive's employment through the Termination Date, the
               Executive shall be entitled to a lump sum payment, within ten
               (10) business days after the expiration of any revocation period
               relating to the Release Agreement described in Section 11 below,
               in an amount equal to the present value (calculated in accordance
               with the terms of the Company's defined benefit plans or
               supplemental plans, based on the age of the Executive at the date
               entitlement to benefits under this Section 6(c)(iii) arises) of
               the excess of (A) the retirement income and other benefits that
               would be payable to the Executive under the defined benefit plans
               (including any supplemental plans) of the Company if the
               Executive was credited with an additional two years of age and
               two years of benefit and credited service in addition to the age
               and total number of years of benefit and credited service the
               Executive has accrued under such plans over (B) the retirement
               income and other benefits the Executive is entitled to receive
               (either immediately or on a deferred basis) under the defined
               benefit plans (including any supplemental plans) of the Company.
               In the event that the Executive, after credit for the additional
               two years, has a total of less than five years of credited
               service, the Executive nonetheless shall be treated as fully
               vested under the defined benefit retirement plans and any
               supplemental retirement plans, but with benefits computed solely
               on the basis of total benefit service.

          (iv) The Executive shall be entitled to outplacement services for a
               time period (not less than six (6) months) established by the
               Company, by a firm selected by the Company in its sole
               discretion, and at the expense of the Company; provided, however,
               that all such outplacement services must be completed by December
               31 of the second calendar year following the calendar year in
               which the Termination Date occurs and the Company will be
               required to make all payments to the Executive for such
               outplacement services by December 31 of the second calendar year
               following the calendar year in which the Termination Date occurs.

          (v)  Notwithstanding anything to the contrary contained in this
               Section 6(c), if payment to the Executive of any amount paid
               pursuant to this Section 6(c) would constitute a "deferral of
               compensation" under Section 409A of the Code (such compensation
               does not, for example, qualify for the "short-term deferral
               exception" under Section 409A of the Code) and the

                                       4

<PAGE>

               Executive is a "specified employee" (as such phrase is defined in
               Section 409A of the Code), the Executive (or the Executive's
               beneficiary) will receive payment of such amounts described in
               this Section 6(c) upon the earlier of (i) six (6) months
               following the Executive's "separation from service" with the
               Company (as such phrase is defined in Section 409A of the Code)
               or (ii) the Executive's death.

     (d)  It is expressly understood that the Company's payment obligations
          under Section 6(c) shall cease in the event the Executive breaches any
          of his or her agreements in Section 7 hereof and, in the event of any
          such breach, the Executive shall repay in cash immediately to the
          Company any amounts previously paid to the Executive under Section
          6(c) of this Agreement.

     (e)  The Executive shall not be required to mitigate the amount of any
          payment or benefit provided for in this Agreement by seeking other
          employment or otherwise.

7.   Competitive Activity; Confidentiality; Nonsolicitation.

     (a)  Acknowledgements and Agreements. The Executive hereby acknowledges and
          agrees that in the performance of the Executive's duties for the
          Company during the Employment Period, the Executive will be brought
          into frequent contact, either in person, by telephone or through the
          mails, with existing and potential customers of the Company throughout
          the United States. The Executive also agrees that trade secrets and
          confidential information of the Company, more fully described in
          Section 7(i) of this Agreement, gained by the Executive during the
          Executive's association with the Company, have been developed by the
          Company through substantial expenditures of time, effort and money and
          constitute valuable and unique property of the Company. The Executive
          further understands and agrees that the foregoing makes it necessary
          for the protection of the business of the Company that the Executive
          not compete with the Company during the Employment Period and not
          compete with the Company for a reasonable period thereafter, as
          further provided in the following subsections.

          but without limiting its terms, during the Employment Period, the

          (iv) promote or assist, financially or otherwise, any person, firm,
               association, partnership, corporation or other entity engaged in
               any business which competes with the business of the Company.

     (c)  Covenants Following Termination. For a period of two (2) years
          following the termination of the Executive's employment for any
          reason, unless the Executive is entitled to severance benefits under a
          severance agreement between the Executive and the Company providing
          for payment of benefits upon a termination of employment following a
          change in control of the Company and containing covenants made by the
          Executive with respect to the subject matter of this Section 7(c) (a
          "Severance Agreement"), in which case those covenants contained in
          such Severance Agreement shall apply to the Executive in lieu of the
          application of this Section 7, the Executive will not:

          (i)  enter into or engage in any business which competes with the
               Company's business within the United States;

          (ii) solicit customers, business, patronage or orders for, or sell,
               any products and services in competition with, or for any
               business, wherever located, that competes with, the Company's
               business within the United States;

          (iii) divert, entice or otherwise take away any customers, business,
               patronage or orders of the Company within the United States, or
               attempt to do so; or

          (iv) promote or assist, financially or otherwise, any person, firm,
               association, partnership, corporation or other entity engaged in
               any business which competes with the Company's business within
               the United States.

     (d)  Indirect Competition. For the purposes of Sections 7(b) and 7(c), but
          without limitation thereof, the Executive will be in violation thereof
          if the Executive engages in any or all of the activities set forth
          therein directly as an individual on the Executive's own account, or
          indirectly as a general partner, joint venturer, employee, agent,
          salesperson, consultant, officer and/or director of any firm,
          association, partnership, corporation or other entity, or as a limited
          partner, member or stockholder of any limited partnership, limited
          liability company, or corporation in which the Executive or the
          Executive's spouse, child or parent owns, directly or indirectly,
          individually or in the aggregate, more than five percent (5%) of the
          limited partnership interests, limited liability company interests or
          outstanding stock, as the case may be.

     (e)  The Company. For purposes of this Section 7, the Company shall include
          any and all Subsidiaries of the Company.

     (f)  The Company's Business. For the purposes of Sections 7(b), 7(c), 7(j)
          and 7(k), the Company's business is defined to be the manufacture and
          distribution of gypsum wallboard, joint compound and related gypsum
          products, cement board, gypsum fiber panels, ceiling panels and grid,
          the distribution of building products and any future businesses the
          Company may enter, as further described in any and

                                       6

<PAGE>

          all manufacturing, marketing and sales manuals and materials of the
          Company as the same may be altered, amended, supplemented or otherwise
          changed from time to time, or of any other products or services
          substantially similar to or readily substitutable for any such
          described products and services.

     (g)  Extension. If it shall be judicially determined that the Executive has
          violated any of the Executive's obligations under Section 7(c), then
          the period applicable to each obligation that the Executive shall have
          been determined to have violated shall automatically be extended by a
          period of time equal in length to the period during which such
          violation(s) occurred.

     (h)  Non-Solicitation. Until the expiration of three (3) years following
          the Termination Date, the Executive will not directly or indirectly at
          any time solicit or induce or attempt to solicit or induce any
          employee(s), sales representative(s), agent(s) or consultant(s) of the
          Company and/or of its Subsidiaries to terminate their employment,
          representation or other association with the Company and/or its
          Subsidiaries.

     (i)  Further Covenants.

          (i)  The Executive will keep in strict confidence, and will not,
               without the prior written consent of the Company or as may
               otherwise be required by law or legal process, directly or
               indirectly, at any time during or after the Executive's
               employment with the Company, disclose, furnish, disseminate, make
               available or, except in the course of performing the Executive's
               duties of employment, use any trade secrets or non-public
               confidential business and technical information of the Company or
               its customers or vendors, including without limitation as to when
               or how the Executive may have acquired such information before or
               during employment. Such confidential information shall include,
               without limitation, the Company's unique non-public confidential
               selling, manufacturing and servicing methods and business
               techniques, training, service and business manuals, promotional
               materials, training courses and other training and instructional
               materials, vendor and product information, customer and
               prospective customer lists, other customer and prospective
               customer information and other business information. The
               Executive specifically acknowledges that all such non-public
               confidential information, whether reduced to writing, maintained
               on any form of electronic media, or maintained in the Executive's
               mind or memory and whether compiled by the Company and/or the
               Executive, derives independent economic value from not being
               readily known to or ascertainable by proper means by others who
               can obtain economic value from its disclosure or use, that
               reasonable efforts have been made by the Company to maintain the
               secrecy of such information, that such information is the sole
               property of the Company and that any retention and use of such
               information by the Executive during the Executive's employment
               with the Company (except in the course of performing the

                                       7

<PAGE>

               Executive's duties and obligations to the Company) or after the
               termination of the Executive's employment shall constitute a
               misappropriation of the Company's trade secrets.

          (ii) The Executive agrees that upon termination of the Executive's
               employment with the Company, for any reason, the Executive shall
               return to the Company, in good condition, all property of the
               Company, including without limitation, the originals and all
               copies of any materials which contain, reflect, summarize,
               describe, analyze or refer or relate to any items of information
               listed in Section 7(i)(i) of this Agreement. In the event that
               such items are not so returned, the Company will have the right
               to charge the Executive for all reasonable damages, costs,
               attorneys' fees and other expenses incurred in searching for,
               taking, removing and/or recovering such property.

     (j)  Discoveries and Inventions; Work Made for Hire.

          (i)  The Executive hereby assigns and agrees to assign to the Company,
               its successors, assigns or nominees, all of the Executive's
               rights to any discoveries, inventions and improvements, whether
               patentable or not, made, conceived or suggested, either solely or
               jointly with others, by the Executive while in the Company's
               employ with the use of the Company's time, material or facilities
               or in any way within or related to the existing or contemplated
               scope of the Company's business. Any discovery, invention or
               improvement relating to any subject matter with which the Company
               was concerned during the Executive's employment and made,
               conceived or suggested by the Executive, either solely or jointly
               with others, within one (1) year following termination of the
               Executive's employment under this Agreement or any successor
               agreements shall be irrebuttably presumed to have been so made,
               conceived or suggested in the course of such employment with the
               use of the Company's time, materials or facilities. Upon request
               by the Company with respect to any such discoveries, inventions
               or improvements, the Executive will execute and deliver to the
               Company, at any time during or after the Executive's employment,
               all appropriate documents for use in applying for, obtaining and
               maintaining such domestic and foreign patents as the Company may
               desire, and all proper assignments therefor, when so requested,
               at the expense of the Company, but without further or additional
               consideration.

          (ii) The Executive acknowledges that, to the extent permitted by law,
               all work papers, reports, documentation, drawings, photographs,
               negatives, tapes and masters therefor, prototypes and other
               materials (hereinafter, "items"), including without limitation,
               any and all such items generated and maintained on any form of
               electronic media, generated by the Executive during the
               Executive's employment with the Company shall be considered a
               "work made for hire" and that ownership of any and all copyrights
               in any and all such items shall belong to the Company. The item
               will

                                       8

<PAGE>

               recognize the Company as the copyright owner, will contain all
               proper copyright notices, e.g., "(creation date) [Company Name],
               All Rights Reserved," and will be in condition to be registered
               or otherwise placed in compliance with registration or other
               statutory requirements throughout the world.

     (k)  Communication of Contents of Agreement. During the Executive's
          employment and for two (2) years thereafter, the Executive will
          communicate the contents of this Agreement to any person, firm,
          association, partnership, corporation or other entity which the
          Executive intends to be employed by, associated with, or represent and
          which is engaged in a business that is competitive to the business of
          the Company.

     (l)  Non-Disparagement. The Executive and his immediate family agree to
          refrain from criticizing or making disparaging or derogatory comments
          about the Company or any Subsidiary and any of their respective
          officers, directors, employees and agents or any products or services
          of the Company or any Subsidiary.

     (m)  Relief. The Executive acknowledges and agrees that the remedy at law
          available to the Company for breach of any of the Executive's
          obligations under this Agreement would be inadequate. The Executive
          therefore agrees that, in addition to any other rights or remedies
          that the Company may have at law or in equity, temporary and permanent
          injunctive relief may be granted in any proceeding which may be
          brought to enforce any provision contained in Sections 7(b), 7(c),
          7(h), 7(i), 7(j) 7(k) and 7(l) of this Agreement, without the
          necessity of proof of actual damage.

     (n)  Reasonableness. The Executive acknowledges that the Executive's
          obligations under this Section 7 are reasonable in the context of the
          nature of the Company's business and the competitive injuries likely
          to be sustained by the Company if the Executive was to violate such
          obligations. The Executive further acknowledges that this Agreement is
          made in consideration of, and is adequately supported by, the
          agreement of the Company to perform its obligations under this
          Agreement and by other consideration, which the Executive acknowledges
          constitutes good, valuable and sufficient consideration.

8.   Golden Parachute Excise Tax. The amounts payable to the Executive under
     Section 6 shall be adjusted as set forth in this Section 8 if the sum (the
     "combined amount") of the amounts payable under Section 6 and all other
     payments or benefits which the Executive has received or has the right to
     receive from the Company which are defined in Section 280G(b)(2)(A)(i) of
     the Code, would constitute a "parachute payment" (as defined in Section
     280G(b)(2) of the Code). In such event, the combined amount shall, unless
     the following sentence applies, be decreased by the smallest amount that
     will eliminate any parachute payment. If the decrease referred to in the
     preceding sentence is 10% or more of the combined amount, the combined
     amount shall not be decreased, but rather shall be increased by an amount
     (the "Gross Up Payment") sufficient to provide the Executive,

                                       9

<PAGE>

     after tax, a net amount equal to the Code Section 4999 excise tax imposed
     on such combined amount, as increased pursuant to this section. For this
     purpose, "after tax" means the amount retained by the Executive after
     satisfaction (whether through withholding, direct payment or otherwise) of
     all applicable federal, state, provincial and local income taxes at the
     highest marginal tax rate, and the employee share of any applicable FICA
     taxes. To the extent a Gross-Up Payment is due to the Executive pursuant to
     this Section 8, the Gross-Up Payment shall be made on the date the lump sum
     payments provided in Section 6 are made and shall include all Gross-Up
     Payments due in respect of payments made before, payments made at the same
     time as, and payments projected to be made after such payment date;
     provided, however, that in accordance with Section 280G, such Gross-Up
     Payment shall not include taxes imposed by Section 4999 for health
     insurance benefits, which shall be paid and withheld by the Company at the
     same date that income taxes are withheld from such health insurance
     benefits. If at a time subsequent to any payment under Section 6, an
     additional amount of Code Section 4999 excise tax is definitively
     determined to be due by either the Internal Revenue Service or a court of
     competent jurisdiction, the Company shall pay to the Executive an
     additional amount which, net of Federal, state, provincial and local
     income, FICA and Code Section 4999 excise taxes, will satisfy such
     additional Code Section 4999 excise tax, including applicable interest and
     penalties. The parties acknowledge that, if the decrease referred to in the
     second sentence of this Section 8 is 10% or more of the combined amount,
     the intention of the preceding sentences in this Section 8 is to place the
     Executive in the position in which the Executive would be if the Code
     Section 4999 excise tax did not exist. Notwithstanding the foregoing
     provisions of this Section 8, Gross-Up Payments, including any additional
     payment made subsequent to any payment under Section 6, will be made only
     in a manner and to the extent (and at the earliest date(s)) such that
     Section 409A of the Code will not be violated.

     interpreted in such manner as to be effective and valid under applicable
     law, but if any provision of this Agreement is held to be invalid or
     unenforceable in any respect under any applicable law or rule in any
     jurisdiction, such invalidity or unenforceability shall not affect any
     other provision of this Agreement, but this Agreement shall be reformed,
     construed and enforced in such jurisdiction as if such invalid or
     unenforceable provision had never been contained herein.

16.  Complete Agreement. This Agreement embodies the complete agreement and
     understanding between the parties with respect to the employment of the
     Executive and the subject matter hereof and effective as of its date
     supersedes and preempts any prior understandings, agreements or
     representations by or between the parties, written or oral, which may have
     related to the subject matter hereof in any way, including any prior
     Employment Agreements between the Company and the Executive. The severance
     benefits provided in Section 6(c) hereof shall be in lieu of any severance
     benefits under any plans, programs, policies or practices of the Company;
     provided, however, that if the Executive is entitled to benefits under this
     Agreement and a Severance Agreement, the Executive will be entitled to
     severance benefits under either this Agreement or such Severance Agreement,
     whichever agreement provides for greater benefits, but will not be entitled
     to benefits under both agreements.

17.  Counterparts. This Agreement may be executed in separate counterparts, each
     of which shall be deemed to be an original and both of which taken together
     shall constitute one and the same agreement.

18.  Successors and Assigns. This Agreement shall bind and inure to the benefit
     of and be enforceable by the Executive, the Company and their respective
     heirs, executors, personal representatives, successors and assigns, except
     that neither party may assign any rights or delegate any obligations
     hereunder without the prior written consent of the other party. The
     Executive hereby consents to the assignment by the Company of all of its
     rights and obligations hereunder to any successor to the Company by merger
     or consolidation or purchase of all or substantially all of the Company's
     assets, provided such transferee or successor assumes the liabilities of
     the Company hereunder.

19.  Governing Law. The validity, interpretation, construction and performance
     of this Agreement will be governed by and construed in accordance with the
     substantive laws of the State of Delaware and federal law, without giving
     effect to the principles of conflict of laws of such State, except as
     expressly provided herein.

20.  Amendment and Waiver. The provisions of this Agreement may be amended or
     waived only with the prior written consent of the Company and the
     Executive, and no course of conduct or failure or delay in enforcing the
     provisions of this Agreement shall affect the validity, binding effect or
     enforceability of this Agreement.

21.  Section 409A of the Code. To the extent applicable, it is intended that
     this Agreement comply with the provisions of Section 409A of the Code. This
     Agreement shall be administered in a manner consistent with this intent,
     and any provision that would cause the Agreement to fail to satisfy Section
     409A of the Code shall have no force and effect until amended to comply
     with Section 409A of the Code (which amendment may be retroactive to the
     extent permitted by Section 409A of the Code and may be made by the Company
     without the consent of the Executive).

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first written above.
