                                 USG CORPORATION

                      CHANGE IN CONTROL SEVERANCE AGREEMENT

     THIS CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Agreement"), dated as of
January 1, 2007, is made and entered into by and between USG Corporation, a
Delaware corporation (the "Company"), and ___________________ (the "Executive").

                                    RECITALS:

     I. The Executive is a senior executive of the Company or a Subsidiary and
has made and is expected to continue to make major contributions to the growth
and financial strength of the Company;

     II. The Company recognizes that the possibility of a Change in Control (as
defined below) exists and that such possibility, and the uncertainty it may
create among management, may result in the distraction or departure of
management personnel, to the detriment of the Company and its stockholders;

     III. The Company desires to assure itself of the continuity of management
and desires to establish certain minimum severance benefits for certain of its
senior executives, including the Executive, applicable in the event of a Change
in Control;

     IV. The Company wishes to ensure that its senior executives are not unduly
distracted by the circumstances attendant to the possibility of a Change in
Control and to encourage the continued attention and dedication of such
executives, including the Executive, to their assigned duties with the Company;
and

     V. The Company desires to provide additional inducement for the Executive
to continue to remain in the employ of the Company.

     NOW, THEREFORE, the Company and the Executive agree as follows:

1.   Certain Defined Terms. In addition to terms defined elsewhere herein, the
     following terms have the following meanings when used in this Agreement
     with initial capital letters:

     (a)  "Base Pay" means the Executive's annual base salary rate as in effect
          from time to time.

     (b)  "Board" means the Board of Directors of the Company.

     (c)  "Cause" means that, prior to any termination pursuant to Section 3(b),
          the Executive shall have:

<PAGE>

          (i)  been convicted of a criminal violation involving fraud,
               embezzlement or theft in connection with the Executive's duties
               or in the course of the Executive's employment with the Company
               or any Subsidiary;

          (ii) committed intentional wrongful damage to tangible or intangible
               property of the Company or any Subsidiary; or

          (iii) committed intentional wrongful disclosure of secret processes or
               confidential information of the Company or any Subsidiary.

          For purposes of this Agreement, no act or failure to act on the part
          of the Executive will be deemed "intentional" if it was due primarily
          to an error in judgment or negligence, but will be deemed
          "intentional" only if done or omitted to be done by the Executive not
          in good faith and without reasonable belief that the Executive's
          action or omission was in the best interest of the Company.
          Notwithstanding the foregoing, the Executive will not be deemed to
          have been terminated for "Cause" hereunder unless and until there
          shall have been delivered to the Executive a copy of a resolution duly
          adopted by the affirmative vote of not less than a majority of the
          Board then in office (excluding the Executive if the Executive is then
          a member of the Board) at a meeting of the Board called and held for
          such purpose, after reasonable notice to the Executive and an
          opportunity for the Executive, together with the Executive's counsel
          (if the Executive chooses to have counsel present at such meeting), to
          be heard before the Board, finding that, in the good faith opinion of
          the Board, the Executive had committed an act constituting "Cause" as
          herein defined and specifying the particulars thereof in reasonable
          detail. Nothing herein will limit the right of the Executive or the
          Executive's beneficiaries to contest the validity or propriety of any
          such determination.

     (d)  "Change in Control" means the occurrence during the Term of any of the
          following events:

          (i)  any individual, entity or group (within the meaning of Section
               13(d)(3) or 14(d)(2) of the Exchange Act) (a "Person") is or
               becomes the beneficial owner (within the meaning of Rule 13d-3
               promulgated under the Exchange Act) of 20% or more of the
               combined voting power of the then-outstanding Voting Stock of the
               Company; provided, however, that:

               (1)  for purposes of this Section 1(d), the following
                    acquisitions shall not constitute a Change in Control: (A)
                    any acquisition of Voting Stock of the Company directly from
                    the Company that is approved by a majority of the Incumbent
                    Directors, (B) any acquisition of Voting Stock of the
                    Company by the Company or any Subsidiary, (C) any
                    acquisition of Voting Stock of the Company by the trustee or
                    other fiduciary holding securities under any employee
                    benefit plan (or related trust) sponsored or maintained by
                    the Company or any Subsidiary, and (D) any acquisition of
                    Voting Stock of the

                                        2

<PAGE>

                    Company by any Person pursuant to a Business Transaction
                    that complies with clauses (A), (B) and (C) of Section
                    1(d)(iii) below;

               (2)  if any Person is or becomes the beneficial owner of 20% or
                    more of combined voting power of the then-outstanding Voting
                    Stock of the Company as a result of a transaction described
                    in clause (A) of Section 1(d)(i)(1) above and such Person
                    thereafter becomes the beneficial owner of any additional
                    shares of Voting Stock of the Company representing 1% or
                    more of the then-outstanding Voting Stock of the Company,
                    other than in an acquisition directly from the Company that
                    is approved by a majority of the Incumbent Directors or
                    other than as a result of a stock dividend, stock split or
                    similar transaction effected by the Company in which all
                    holders of Voting Stock are treated equally, such subsequent
                    acquisition shall be treated as a Change in Control;

               (3)  a Change in Control will not be deemed to have occurred if a
                    Person is or becomes the beneficial owner of 20% or more of
                    the Voting Stock of the Company as a result of a reduction
                    in the number of shares of Voting Stock of the Company
                    outstanding pursuant to a transaction or series of
                    transactions that is approved by a majority of the Incumbent
                    Directors unless and until such Person thereafter becomes
                    the beneficial owner of any additional shares of Voting
                    Stock of the Company representing 1% or more of the
                    then-outstanding Voting Stock of the Company, other than as
                    a result of a stock dividend, stock split or similar
                    transaction effected by the Company in which all holders of
                    Voting Stock are treated equally; and

               (4)  if at least a majority of the Incumbent Directors determine
                    in good faith that a Person has acquired beneficial
                    ownership of 20% or more of the Voting Stock of the Company
                    inadvertently, and such Person divests as promptly as
                    practicable but no later than the date, if any, set by the
                    Incumbent Board a sufficient number of shares so that such
                    Person beneficially owns less than 20% of the Voting Stock
                    of the Company, then no Change in Control shall have
                    occurred as a result of such Person's acquisition; or

          (ii) a majority of the Board ceases to be comprised of Incumbent
               Directors; or

          (iii) the consummation of a reorganization, merger or consolidation,
               or sale or other disposition of all or substantially all of the
               assets of the Company or the acquisition of the stock or assets
               of another corporation, or other transaction (each, a "Business
               Transaction"), unless, in each case, immediately following such
               Business Transaction (A) the Voting Stock of the Company
               outstanding immediately prior to such Business Transaction
               continues to represent (either by remaining outstanding or by
               being

                                       3

               thereof), more than 60% of the combined voting power of the then
               outstanding shares of Voting Stock of the entity resulting from
               such Business Transaction (including, without limitation, an
               entity which as a result of such transaction owns the Company or
               all or substantially all of the Company's assets either directly
               or through one or more subsidiaries), (B) no Person (other than
               the Company, such entity resulting from such Business
               Transaction, or any employee benefit plan (or related trust)
               sponsored or maintained by the Company, any Subsidiary or such
               entity resulting from such Business Transaction) beneficially
               owns, directly or indirectly, 20% or more of the combined voting
               power of the then outstanding shares of Voting Stock of the
               entity resulting from such Business Transaction, and (C) at least
               a majority of the members of the Board of Directors of the entity
               resulting from such Business Transaction were Incumbent Directors
               at the time of the execution of the initial agreement or of the
               action of the Board providing for such Business Transaction; or

          (iv) approval by the stockholders of the Company of a complete
               liquidation or dissolution of the Company, except pursuant to a
               Business Transaction that complies with clauses (A), (B) and (C)
               of Section 1(d)(iii).

     Notwithstanding anything in this Agreement to the contrary, a Change in
     Control shall not be deemed to have occurred as a result of an acquisition
     or the holding of Voting Stock of the Company permitted by Section 2(a) of

               responsibilities, including, but not limited to, the assignment
               without the Executive's written consent of any diminished duties
               and responsibilities which are inconsistent with the Executive's
               positions, duties and responsibilities with the Company
               immediately prior to a Change in Control, or a materially adverse
               change in the Executive's reporting responsibilities or titles as
               in effect immediately prior to the Change in Control, whether or
               not resulting from an act of the Company or otherwise, or any
               removal of the Executive from or any failure to re-elect the

               continues to serve as a member of the Board of the Company (or
               any successor thereto) following the Change in Control, the
               Company's securities are no longer publicly traded; provided,
               however,that Good Reason shall not exist if the Executive becomes
               a member of the board of directors of a publicly-traded entity
               that as a result of the Change in Control owns the Company or
               substantially all of the Company's assets either directly or

               to the Change in Control, except for required travel on the
               Company's business to an extent substantially consistent with
               business travel obligations immediately prior to the Change in
               Control;

          (vi) the failure by the Company to continue in effect any investment
               plan, retirement plan, savings plan, supplemental retirement
               plan, deferred compensation plan, supplemental investment plan,
               life insurance plan, health and accident plan, disability plan or
               other welfare benefit plan in which the Executive was
               participating at the time of the Change in Control (or plans
               providing the Executive with substantially similar benefits), the
               taking of any action by the Company which would adversely affect
               the Executive's participation or materially reduce the

               the date of the Change in Control; or

          (vii) the failure by the Company to obtain the assumption of the
               obligation to perform this Agreement by any successor as
               contemplated in Section 11 hereof.

     (h)  "Incumbent Directors" means the individuals who, as of the date of
          this Agreement, are Directors of the Company and any individual
          becoming a Director subsequent to the date of this Agreement whose
          election, nomination for election by the Company's stockholders, or
          appointment, was approved by a vote of at least two-thirds of the then
          Incumbent Directors (either by a specific vote or by approval of the
          proxy statement of the Company in which such person is named as a
          nominee for director, without objection to such nomination); provided,
          however, that an individual shall not be an Incumbent Director if such
          individual's election or appointment to the Board occurs as a result
          of an actual or threatened election contest (as described in Rule
          14a-12(c) of the Exchange Act) with respect to the election or removal
          of Directors or other actual or threatened solicitation of proxies or
          consents by or on behalf of a Person other than the Board.

     (i)  "Release Agreement" means an agreement, in substantially the form
          customarily used by the Company for similarly situated executives of
          the Company in similar instances, pursuant to which the Executive
          releases, to the extent permitted by law, all current or future
          claims, known or unknown, arising on or before the date of the release
          against the Company, its subsidiaries and its officers.

     (j)  "Severance Period" means the period of time commencing on the date of
          the first occurrence of a Change in Control and continuing until the
          earlier of (i) the second anniversary of the occurrence of the Change
          in Control, or (ii) the Executive's death.

     (k)  "Subsidiary" means a corporation, company or other entity (i) at least
          50 percent of whose outstanding shares or securities (representing the
          right to vote for the election of directors or other managing
          authority) are, or (ii) which does not have outstanding shares or
          securities (as may be the case in a partnership, joint venture or
          unincorporated association), but at least 50 percent of whose
          ownership interest representing the right generally to make decisions
          for such other entity is, now or hereafter, owned or controlled,
          directly or indirectly, by the Company.

     (l)  "Target Annual Direct Compensation" means the sum of the Executive's
          Base Pay, target annual incentive opportunity, and the annualized
          value of the most recent long-term incentive award approved by the
          Compensation and Organization Committee of the Board. For purposes of
          measuring annualized long-term incentives, the awards shall be
          measured on their date of grant using reasonable assumptions,
          including, but not limited to, fair value principles such as those
          identified in Statement of Financial Accounting Standards No. 123,
          Share-Based Payment; the value of such awards shall be annualized over
          the frequency of their grant. Notwithstanding the foregoing, if, for
          purposes of calculating "Target Annual Direct Compensation," the most
          recent long-term incentive award would be the long-term incentive
          award granted in August 2006 (the "2006 Award"), the calculation of
          "Target Annual Direct Compensation" will include only 50% of the value
          of such 2006 Award.

          the Term is not to renew; provided, however, that (i) if a Change in

          than, the last day of the Severance Period; and (ii) subject to
          Section 3(c), if, prior to a Change in Control, the Executive ceases
          for any reason to be an officer of the Company or an employee of the
          Company or any Subsidiary, thereupon without further action the Term
          shall be deemed to have expired and this Agreement will immediately
          terminate and be of no further effect. For purposes of this Section
          1(m), the Executive shall not be deemed to have ceased to be an
          employee of the Company and any Subsidiary by reason of the transfer
          of the Executive's employment between the Company and any Subsidiary,
          or among Subsidiaries.

     (n)  "Termination Date" means the date on which the Executive's employment
          is terminated (the effective date of which will be the date of
          termination, or such other date that may be specified by the Executive
          if the termination is pursuant to Section 3(b)).

     (o)  "Voting Stock" means at any time, the then-outstanding securities
          entitled to vote generally in the election of directors of the
          Company.

     immediately upon its execution, but, anything in this Agreement to the
     contrary notwithstanding, except as provided in Section 3(c), the payments
     and benefits provided under this Agreement will not be payable unless and
     until a Change in Control occurs. Upon the occurrence of a Change in
     Control at any time during the Term, without further action, this Agreement
     will become immediately operative.

3.   Termination Following a Change in Control.

     (a)  If a Change in Control occurs and the Executive's employment is
          terminated by the Company or a Subsidiary during the Severance Period
          (or pursuant to Section 3(c)), the Executive will be entitled to the
          benefits provided by Section 4 unless such termination is the result
          of the occurrence of one or more of the following events:

          (i)  The Executive's death;

          (ii) The Executive's having become unable (as determined by the Board
               in good faith), with or without reasonable accommodations, to
               regularly perform the Executive's duties by reason of illness or
               incapacity; or

          (iii) Cause.

     (b)  In the event of the occurrence of a Change in Control, the Executive
          may terminate employment with the Company and any Subsidiary during
          the Severance Period for Good Reason with the right to severance
          compensation as provided in Section 4 regardless of whether any other
          reason, other than Cause, for such termination exists or has occurred,
          including without limitation other employment.

     (c)  Anything in this Agreement to the contrary notwithstanding, if a
          Change in Control occurs and not more than 90 days prior to the date
          on which the Change in Control occurs, the Executive's employment with
          the Company is terminated by the Company, such termination of
          employment will be deemed to be a termination of employment after a
          Change in Control for purposes of this Agreement and, in addition, the
          Company will be required to pay to the Executive in a lump sum in
          cash, the sum of: (1) the difference between the fair market value of
          a common share of the Company and the exercise price of each
          outstanding stock option held by the Executive that was forfeited as a
          result of the Executive's termination of employment multiplied by the
          number of shares underlying each stock option held by the Executive
          that was forfeited as a result of the Executive's termination of
          employment and (2) the fair market value of a common share of the
          Company multiplied by the number of shares underlying each share of
          restricted stock and each performance share and other equity award
          held by the Executive that was forfeited as a result of the
          Executive's termination of employment. For this purpose, the "fair
          market value of a common share of the Company" shall be deemed to be
          the price per share paid in connection with the Change in Control.

     (d)  A termination of employment pursuant to Section 3(a), 3(b) or 3(c)
          will not affect any rights that the Executive may have pursuant to any
          agreement, policy, plan, program or arrangement of the Company or any
          Subsidiary providing employee benefits, which rights will be governed
          by the terms thereof; provided, however, that if upon termination of
          employment, the Executive is entitled to severance compensation or
          benefits under this Agreement and pursuant to any employment or
          severance agreement or employee plan (an "Employment Agreement"), the
          Executive will be entitled to severance benefits under either this
          Agreement or such Employment Agreement, whichever agreement provides
          for greater benefits, but will not be entitled to benefits under both
          agreements.

4.   Severance Compensation.

     (a)  If, following the occurrence of a Change in Control, the Company or a
          Subsidiary of the Company terminates the Executive's employment during
          the Severance Period other than pursuant to Section 3(a)(i), 3(a)(ii)
          or 3(a)(iii), or if the Executive terminates the Executive's
          employment pursuant to Section 3(b), the Company will be obligated to
          make the following payments and provide the following benefits to the
          Executive.

                                       8

<PAGE>

          (i)  The Executive will be entitled to receive: (i) as soon as
               practicable following the end of the Employment Period, any Base
               Pay 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 date of
               termination of the Executive's employment, (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 this Section 4, any severance pay program or policy
               of the Company or a Subsidiary), and (iii) subject to Section
               4(a)(ii) below, 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. In
               addition, the Executive shall be entitled to the additional
               benefits and amounts described in the succeeding subsections of
               this Section 4, in the circumstances described in such
               subsections.

          (ii) Within ten (10) business days after the expiration of any
               revocation period relating to the Release Agreement described in
               Section 20 below and in lieu of payments under the terms of the
               Company's annual bonus plan applicable to the Executive, the
               Executive will be entitled to receive a lump sum cash payment in
               an amount equal to the greater of (A) the Executive's target or
               par annual bonus for the fiscal year in which the Termination
               Date occurs or (B) the Executive's target or par annual bonus for
               the fiscal year in which the Change in Control occurs, pro-rated
               for the number of full months that the Executive was employed
               during such fiscal year (i.e., the annual bonus shall be
               multiplied by a fraction, the numerator of which is the number of
               full months during which the Executive was actively employed by
               the Company in the relevant fiscal year and the denominator of
               which is 12).

          (iii) Within ten (10) business days after the expiration of any
               revocation period relating to the Release Agreement described in
               Section 20 below, the Executive will be entitled to receive a
               lump sum cash payment in an amount equal to three (3) times the
               sum of (A) Base Pay (at the highest rate in effect for any period
               within three years prior to the Termination Date), plus (B)
               annual bonus (in an amount equal to the greater of the
               Executive's target or par annual bonus for the year in which the
               Termination Date occurs or for the year in which the Change in
               Control occurs, whichever is greater).

          (iv) For a period of eighteen (18) months following the Termination
               Date (the "Continuation Period"), the Executive will be entitled
               to continued participation in the Company's medical, dental,
               vision, long-term disability and life insurance plans (excluding
               benefits under the executive

                                       9

<PAGE>

               death benefit plan) (the "Benefit Plans"), subject to the terms
               and conditions of the Benefit Plans, including, but not limited
               to, timely payment of any employee contributions necessary to
               maintain participation; provided, however,that (A) such coverage
               shall be provided only to the extent that such coverage would not
               be considered "deferred compensation" subject to the requirements
               of Section 409A of the Code; and (B) the Executive's continued
               participation in the Benefit Plans during the Continuation Period
               shall satisfy the Benefit Plans' obligation, if any, to provide
               the Executive the right to continuation coverage under the
               Benefit Plans pursuant to the Consolidated Omnibus Budget
               Reconciliation Act of 1986, as amended. If any benefit described
               in this Section 4(a)(iv) 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 (including any income or social
               security tax) imposed on the benefits described in this Section
               4(a)(iv) and any such additional payment by the Company, the
               recipient retains an amount equal to such taxes. Notwithstanding
               the foregoing, if the Company determines that the provision of
               benefits under this Section 4(a)(iv) would be likely to result in
               negative tax consequences to the Executive, the Company will use
               its reasonable best efforts to make other arrangements to provide
               a substantially similar benefit to the Executive that does not
               have such negative tax consequences, which may include, making a
               lump sum payment at the earliest time permitted under Section
               409A of the Code, in an amount equal to the Company's reasonable
               determination of the present value of any such benefits that, if
               provided, would result in negative tax consequences to the
               Executive and/or providing such benefit through insurance
               coverage on the Executive's behalf.

          (v)  Within ten (10) business days after the expiration of any
               revocation period relating to the Release Agreement described in
               Section 20 below, the Executive will be entitled to receive a
               lump sum cash payment in an amount equal to the present value of
               continued participation in the Benefit Plans for an additional 18
               months. If any benefit described in this Section 4(a)(v) 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 (including any income or social security tax) imposed
               on the benefits described in this Section 4(a)(v) and any such
               additional payment by the Company, the recipient retains an
               amount equal to such taxes.

          (vi) 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 cash payment, within
               five (5) business days after the expiration of any revocation
               period relating to the Release Agreement described in

                                       10

<PAGE>

               Section 20 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
               4(a)(vi) 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 three
               years of age and three 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 three 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.

          (vii) 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.

     (b)  Notwithstanding anything to the contrary contained in this Section 4,
          if any payment to the Executive under this Section 4 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 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 4 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.

     (c)  Without limiting the rights of the Executive at law or in equity, if
          the Company fails to make any payment or provide any benefit required
          to be made or provided hereunder on a timely basis, the Company will
          pay interest on the amount or value thereof at an annualized rate of
          interest equal to the "prime rate" as set forth from time to time
          during the relevant period in The Wall Street Journal "Money Rates"
          column. Such interest will be payable as it accrues on demand. Any
          change in such prime rate will be effective on and as of the date of
          such change.

                                       11

5.   Golden Parachute Excise Tax. The amounts payable to the Executive under
     Section 4 shall be adjusted as set forth in this Section 5 if the sum (the
     "combined amount") of the amounts payable under Section 4 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, 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 5, the Gross-Up Payment shall be made on the date the lump sum
     payments provided in Section 4 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 4, 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 5 is 10% or more of the combined amount,
     the intention of the preceding sentences in this Section 5 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 5, Gross-Up Payments, including any additional
     payment made subsequent to any payment under Section 4, 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.

6.   No Mitigation Obligation. The Company hereby acknowledges that it will be
     difficult and may be impossible for the Executive to find reasonably
     comparable employment following the Termination Date. Accordingly, the
     payment of the severance compensation by the Company to the Executive in
     accordance with the terms of this Agreement is hereby acknowledged by the
     Company to be reasonable, and the Executive will not be required to
     mitigate the amount of any payment provided for in this Agreement by
     seeking other employment or otherwise, nor will any profits, income,
     earnings or other benefits from any source whatsoever create any
     mitigation, offset, reduction or any other obligation on the part of the
     Executive hereunder or otherwise.

                                       12

7.   Legal Fees and Expenses.

     (a)  If it should appear to the Executive that the Company has failed to
          comply with any of its obligations under this Agreement or in the
          event that the Company or any other person takes or threatens to take
          any action to declare this Agreement void or unenforceable, or
          institutes any proceeding designed to deny, or to recover from, the
          Executive the benefits provided or intended to be provided to the
          Executive hereunder, the Company irrevocably authorizes the Executive
          from time to time to retain counsel of the Executive's choice, at the
          expense of the Company as hereafter provided, to advise and represent
          the Executive in connection with any such dispute or proceeding.
          Without respect to whether the Executive prevails, in whole or in
          part, in connection with any of the foregoing, the Company will pay
          and be financially responsible for reasonable attorneys' and related
          fees and expenses incurred by the Executive in connection with claims
          made in good faith but only if, and to the extent and at the earliest
          date(s) that, such actions are determined to be permitted without
          violating Section 409A of the Code. Such payments will be made after
          delivery of the Executive's written requests for payment, accompanied
          by such evidence of fees and expenses incurred as the Company may
          reasonably require.

     (b)  Without limiting the obligations of the Company pursuant to Section
          7(a), in the event that (i) the Executive is entitled to benefits
          hereunder and (ii) payments to the Executive would be required to be
          delayed by more than 20 business days due to Section 409A of the Code
          or otherwise, the performance of the Company's obligations under
          Section 4 and this Section 7 will be secured by amounts deposited or
          to be deposited in a grantor trust pursuant to certain trust
          agreements to which the Company will be a party providing that the
          benefits to be paid pursuant to Section 4 and the reasonable fees and
          expenses of counsel selected from time to time by the Executive
          pursuant to Section 7(a) will be paid, or reimbursed to the Executive
          if paid by the Executive, either in accordance with the terms of such
          trust agreements, or, if not so provided, on a regular, periodic basis
          upon presentation by the Executive to the trustee of a statement or
          statements prepared by such counsel in accordance with its customary
          practices. Any failure by the Company to satisfy any of its
          obligations under this Section 7(b) will not limit the rights of the
          Executive hereunder. Subject to the foregoing, the Executive will have
          the status of a general unsecured creditor of the Company and will
          have no right to, or security interest in, any assets of the Company
          or any Subsidiary.

8.   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 Executive's employment, 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

                                       13

<PAGE>

          described in Section 8(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
          Executive's employment and not compete with the Company for a
          reasonable period thereafter, as further provided in the following
          subsections.

     (b)  Covenants During Employment. During the Executive's employment, the
          Executive will not compete with the Company anywhere that the Company
          conducts its business. In accordance with this restriction, but
          without limiting its terms, during the Executive's employment, the
          Executive will not:

          (i)  enter into or engage in any business which competes with the
               business of the Company;

          (ii) solicit customers, business, patronage or orders for, or sell,
               any products and services in competition with, or for any
               business that competes with, the business of the Company;

          (iii) divert, entice or otherwise take away any customers, business,
               patronage or orders of the Company 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 business of the Company.

     (c)  Covenants Following Termination. If, during the Severance Period, the
          Executive's employment is terminated entitling the Executive to
          payments and benefits under Section 4 of this Agreement, for a period
          of one (1) year following the termination of the Executive's
          employment, 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 8(b) and 8(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 8, the Company shall include
          any and all Subsidiaries.

     (f)  The Company's Business. For the purposes of Sections 8(b), 8(c), 8(j)
          and 8(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 that
          the Company may enter, as further described in any and 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 8(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

                                       15

<PAGE>

               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
               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 8(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

                                       16

<PAGE>

               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) 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 recognize the Company as the copyright owner, will contain
               all proper copyright notices, e.g., "(creation date) USG
               Corporation, 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 one (1) year 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)  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 8(b), 8(c),
          8(h), 8(i), 8(j) and 8(k) of this Agreement, without the necessity of
          proof of actual damage.

     (m)  Reasonableness. The Executive acknowledges that the Executive's
          obligations under this Section 8 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,

                                       17

<PAGE>

          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.

9.   Employment Rights. Nothing expressed or implied in this Agreement will
     create any right or duty on the part of the Company or the Executive to
     have the Executive remain in the employment of the Company or any
     Subsidiary prior to or following any Change in Control.

10.  Withholding of Taxes. The Company may withhold from any amounts payable
     under this Agreement all federal, state, city or other taxes as the Company
     is required to withhold pursuant to any applicable law, regulation or
     ruling.

11.  Successors and Binding Agreement.

     (a)  The Company will require any successor (whether direct or indirect, by
          purchase, merger, consolidation, reorganization or otherwise) to all
          or substantially all of the business or assets of the Company, by
          agreement in form and substance reasonably satisfactory to the
          Executive, expressly to assume and agree to perform this Agreement in
          the same manner and to the same extent the Company would be required
          to perform if no such succession had taken place. This Agreement will
          be binding upon and inure to the benefit of the Company and any
          successor to the Company, including without limitation any persons
          acquiring directly or indirectly all or substantially all of the
          business or assets of the Company whether by purchase, merger,
          consolidation, reorganization or otherwise (and such successor will
          thereafter be deemed the "Company" for the purposes of this
          Agreement), but will not otherwise be assignable, transferable or
          delegable by the Company.

     (b)  This Agreement will inure to the benefit of and be enforceable by the
          Executive's personal or legal representatives, executors,
          administrators, successors, heirs, distributees and legatees.

     (c)  This Agreement is personal in nature and neither of the parties hereto
          will, without the consent of the other, assign, transfer or delegate
          this Agreement or any rights or obligations hereunder except as
          expressly provided in Sections 11(a) and 11(b). Without limiting the
          generality or effect of the foregoing, the Executive's right to
          receive payments hereunder will not be assignable, transferable or
          delegable, whether by pledge, creation of a security interest, or
          otherwise, other than by a transfer by the Executive's will or by the
          laws of descent and distribution and, in the event of any attempted
          assignment or transfer contrary to this Section 11(c), the Company
          will have no liability to pay any amount so attempted to be assigned,
          transferred or delegated.

12.  Notices. For all purposes of this Agreement, all communications, including
     without limitation notices, consents, requests or approvals, required or
     permitted to be given hereunder will be in writing and will be deemed to
     have been duly given when hand delivered or dispatched by electronic
     facsimile transmission (with receipt thereof orally confirmed), or five
     business days after having been mailed by United States registered or
     certified mail, return receipt requested, postage prepaid, or three

     courier service such as FedEx or UPS, addressed to the Company (to the
     attention of the Secretary of the Company) at its principal executive
     office and to the Executive at the Executive's principal residence, or to
     such other address as any party may have furnished to the other in writing
     and in accordance herewith, except that notices of changes of address will
     be effective only upon receipt.

13.  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.

14.  Validity. If any provision of this Agreement or the application of any
     provision hereof to any person or circumstance is held invalid or otherwise
     unenforceable, the remainder of this Agreement and the application of such
     provision to any other person or circumstance will not be affected, and the
     provision so held to be invalid or otherwise unenforceable will be reformed
     to the extent (and only to the extent) necessary to make it enforceable or
     valid.

15.  Miscellaneous.

     (a)  No provision of this Agreement may be modified, waived or discharged
          unless such waiver, modification or discharge is agreed to in writing
          signed by the Executive and the Company. No waiver by either party
          hereto at any time of any breach by the other party hereto or
          compliance with any condition or provision of this Agreement to be
          performed by such other party will be deemed a waiver of similar or
          dissimilar provisions or conditions at the same or at any prior or
          subsequent time. No agreements or representations, oral or otherwise,
          expressed or implied with respect to the subject matter hereof have
          been made by either party that are not set forth expressly in this
          Agreement.

     (b)  Subject to Section 3(d), this Agreement supersedes, as of the date
          first above written, any prior agreements providing for severance
          payments and benefits following a Change in Control, including the
          Termination Compensation Agreement, between the Executive and the
          Company (the "Prior Agreements"). The Executive agrees that he or she
          has no further rights under the Prior Agreements.

     (c)  The headings used in this Agreement are intended for convenience or
          reference only and will not in any manner amplify, limit, modify or
          otherwise be used in the construction or interpretation of any
          provision of this Agreement. References to

                                       19

<PAGE>

          Sections are to Sections of this Agreement. Any reference in this
          Agreement to a provision of a statute, rule or regulation will also
          include any successor provision thereto.

16.  Severability. Whenever possible, each provision of this Agreement shall be
     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.

17.  Survival. Notwithstanding any provision of this Agreement to the contrary,
     the parties' respective rights and obligations under Sections 3(d), 4, 5,
     7, 8, 10, 11(b), 16 and 17 will survive any termination or expiration of
     this Agreement or the termination of the Executive's employment following a
     Change in Control for any reason whatsoever.

18.  Beneficiaries. The Executive will be entitled to select (and change, to the
     extent permitted under any applicable law) a beneficiary or beneficiaries
     to receive any compensation or benefit payable hereunder following the
     Executive's death, and may change such election, in either case by giving
     the Company written notice thereof in accordance with Section 12. In the
     event of the Executive's death or a judicial determination of the
     Executive's incompetence, reference in this Agreement to the "Executive"
     will be deemed, where appropriate, to the Executive's beneficiary, estate
     or other legal representative.

19.  Counterparts. This Agreement may be executed in one or more counterparts,
     each of which will be deemed to be an original but all of which together
     will constitute one and the same agreement.

20.  Release Agreement. No payments shall be made under Section 4 hereof if the
     Executive declines to sign and return a Release Agreement or revokes such
     Release Agreement within the time provided therein. If the Executive
     becomes entitled to payments under Section 4 hereof, the Company shall
     deliver to the Executive a copy of the Company's standard form of Release
     Agreement within ten (10) business days of the Executive's Termination
     Date.

21.  Representations. The Executive represents and warrants to the Company that
     upon the execution and delivery of this Agreement by the Company, this
     Agreement shall be the valid and binding obligation of the Executive,
     enforceable in accordance with its terms. The Company represents and
     warrants to the Executive that upon the execution and delivery of this
     Agreement by the Executive, this Agreement shall be the valid and binding
     obligation of the Company, enforceable in accordance with its terms.

                                       20

22.  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.

                      CHANGE IN CONTROL SEVERANCE AGREEMENT

     THIS CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Agreement"), dated as of
January 1, 2007, is made and entered into by and between USG Corporation, a
Delaware corporation (the "Company"), and ____________________ (the
"Executive").

                                    RECITALS:

     I. The Executive is a senior executive of the Company or a Subsidiary and
has made and is expected to continue to make major contributions to the growth
and financial strength of the Company;

     II. The Company recognizes that the possibility of a Change in Control (as
defined below) exists and that such possibility, and the uncertainty it may
create among management, may result in the distraction or departure of
management personnel, to the detriment of the Company and its stockholders;

     III. The Company desires to assure itself of the continuity of management
and desires to establish certain minimum severance benefits for certain of its
senior executives, including the Executive, applicable in the event of a Change
in Control;

     IV. The Company wishes to ensure that its senior executives are not unduly
distracted by the circumstances attendant to the possibility of a Change in
Control and to encourage the continued attention and dedication of such
executives, including the Executive, to their assigned duties with the Company;
and

     V. The Company desires to provide additional inducement for the Executive
to continue to remain in the employ of the Company.

     NOW, THEREFORE, the Company and the Executive agree as follows:

1.   Certain Defined Terms. In addition to terms defined elsewhere herein, the
     following terms have the following meanings when used in this Agreement
     with initial capital letters:

     (a)  "Base Pay" means the Executive's annual base salary rate as in effect
          from time to time.

     (b)  "Board" means the Board of Directors of the Company.

     (c)  "Cause" means that, prior to any termination pursuant to Section 3(b),
          the Executive shall have:

<PAGE>

          (i)  been convicted of a criminal violation involving fraud,
               embezzlement or theft in connection with the Executive's duties
               or in the course of the Executive's employment with the Company
               or any Subsidiary;

          (ii) committed intentional wrongful damage to tangible or intangible
               property of the Company or any Subsidiary; or

          (iii) committed intentional wrongful disclosure of secret processes or
               confidential information of the Company or any Subsidiary.

          For purposes of this Agreement, no act or failure to act on the part
          of the Executive will be deemed "intentional" if it was due primarily
          to an error in judgment or negligence, but will be deemed
          "intentional" only if done or omitted to be done by the Executive not
          in good faith and without reasonable belief that the Executive's
          action or omission was in the best interest of the Company.
          Notwithstanding the foregoing, the Executive will not be deemed to
          have been terminated for "Cause" hereunder unless and until there
          shall have been delivered to the Executive a copy of a resolution duly
          adopted by the affirmative vote of not less than a majority of the
          Board then in office (excluding the Executive if the Executive is then
          a member of the Board) at a meeting of the Board called and held for
          such purpose, after reasonable notice to the Executive and an
          opportunity for the Executive, together with the Executive's counsel
          (if the Executive chooses to have counsel present at such meeting), to
          be heard before the Board, finding that, in the good faith opinion of
          the Board, the Executive had committed an act constituting "Cause" as
          herein defined and specifying the particulars thereof in reasonable
          detail. Nothing herein will limit the right of the Executive or the
          Executive's beneficiaries to contest the validity or propriety of any
          such determination.

     (d)  "Change in Control" means the occurrence during the Term of any of the
          following events:

          (i)  any individual, entity or group (within the meaning of Section
               13(d)(3) or 14(d)(2) of the Exchange Act) (a "Person") is or
               becomes the beneficial owner (within the meaning of Rule 13d-3
               promulgated under the Exchange Act) of 20% or more of the
               combined voting power of the then-outstanding Voting Stock of the
               Company; provided, however, that:

               (1)  for purposes of this Section 1(d), the following
                    acquisitions shall not constitute a Change in Control: (A)
                    any acquisition of Voting Stock of the Company directly from
                    the Company that is approved by a majority of the Incumbent
                    Directors, (B) any acquisition of Voting Stock of the
                    Company by the Company or any Subsidiary, (C) any
                    acquisition of Voting Stock of the Company by the trustee or
                    other fiduciary holding securities under any employee
                    benefit plan (or related trust) sponsored or maintained by
                    the Company or any Subsidiary, and (D) any acquisition of
                    Voting Stock of the

<PAGE>

                    Company by any Person pursuant to a Business Transaction

                    1(d)(iii) below;

               (2)  if any Person is or becomes the beneficial owner of 20% or
                    more of combined voting power of the then-outstanding Voting
                    Stock of the Company as a result of a transaction described
                    in clause (A) of Section 1(d)(i)(1) above and such Person
                    thereafter becomes the beneficial owner of any additional
                    shares of Voting Stock of the Company representing 1% or
                    more of the then-outstanding Voting Stock of the Company,
                    other than in an acquisition directly from the Company that
                    is approved by a majority of the Incumbent Directors or
                    other than as a result of a stock dividend, stock split or
                    similar transaction effected by the Company in which all
                    holders of Voting Stock are treated equally, such subsequent
                    acquisition shall be treated as a Change in Control;

               (3)  a Change in Control will not be deemed to have occurred if a
                    Person is or becomes the beneficial owner of 20% or more of
                    the Voting Stock of the Company as a result of a reduction
                    in the number of shares of Voting Stock of the Company
                    outstanding pursuant to a transaction or series of
                    transactions that is approved by a majority of the Incumbent
                    Directors unless and until such Person thereafter becomes
                    the beneficial owner of any additional shares of Voting
                    Stock of the Company representing 1% or more of the
                    then-outstanding Voting Stock of the Company, other than as
                    a result of a stock dividend, stock split or similar
                    transaction effected by the Company in which all holders of
                    Voting Stock are treated equally; and

               (4)  if at least a majority of the Incumbent Directors determine
                    in good faith that a Person has acquired beneficial
                    ownership of 20% or more of the Voting Stock of the Company
                    inadvertently, and such Person divests as promptly as
                    practicable but no later than the date, if any, set by the
                    Incumbent Board a sufficient number of shares so that such
                    Person beneficially owns less than 20% of the Voting Stock
                    of the Company, then no Change in Control shall have
                    occurred as a result of such Person's acquisition; or

          (ii) a majority of the Board ceases to be comprised of Incumbent
               Directors; or

          (iii) the consummation of a reorganization, merger or consolidation,
               or sale or other disposition of all or substantially all of the
               assets of the Company or the acquisition of the stock or assets
               of another corporation, or other transaction (each, a "Business
               Transaction"), unless, in each case, immediately following such
               Business Transaction (A) the Voting Stock of the Company
               outstanding immediately prior to such Business Transaction
               continues to represent (either by remaining outstanding or by
               being

                                        3

               thereof), more than 60% of the combined voting power of the then
               outstanding shares of Voting Stock of the entity resulting from
               such Business Transaction (including, without limitation, an
               entity which as a result of such transaction owns the Company or
               all or substantially all of the Company's assets either directly
               or through one or more subsidiaries), (B) no Person (other than
               the Company, such entity resulting from such Business
               Transaction, or any employee benefit plan (or related trust)
               sponsored or maintained by the Company, any Subsidiary or such
               entity resulting from such Business Transaction) beneficially
               owns, directly or indirectly, 20% or more of the combined voting
               power of the then outstanding shares of Voting Stock of the
               entity resulting from such Business Transaction, and (C) at least
               a majority of the members of the Board of Directors of the entity
               resulting from such Business Transaction were Incumbent Directors
               at the time of the execution of the initial agreement or of the
               action of the Board providing for such Business Transaction; or

          (iv) approval by the stockholders of the Company of a complete
               liquidation or dissolution of the Company, except pursuant to a
               Business Transaction that complies with clauses (A), (B) and (C)
               of Section 1(d)(iii).

     Notwithstanding anything in this Agreement to the contrary, a Change in
     Control shall not be deemed to have occurred as a result of an acquisition
     or the holding of Voting Stock of the Company permitted by Section 2(a) of

               and responsibilities which are inconsistent with the Executive's
               positions, duties and responsibilities with the Company
               immediately prior to a Change in Control, or a materially adverse
               change in the Executive's reporting responsibilities or titles as
               in effect immediately prior to the Change in Control, whether or
               not resulting from an act of the Company or otherwise, or any
               removal of the Executive from or any failure to re-elect the

                                        4

          (iv) the Company's requiring the Executive, without the Executive's
               written consent, to be based anywhere other than within fifty

               to the Change in Control, except for required travel on the
               Company's business to an extent substantially consistent with

               accordance with the Company's normal vacation policy in effect on
               the date of the Change in Control; or

          (vi) the failure by the Company to obtain the assumption of the

               contemplated in Section 11 hereof.

          election, nomination for election by the Company's stockholders, or
          appointment, was approved by a vote of at least two-thirds of the then
          Incumbent Directors (either by a specific vote or by approval of the
          proxy statement of the Company in which such person is named as a
          nominee for director, without objection to such nomination); provided,
          however, that an individual shall not be an Incumbent Director if such
          individual's election or appointment to the Board occurs as a result
          of an actual or threatened election contest (as described in Rule
          14a-12(c) of the Exchange Act) with respect to the election or removal
          of Directors or other actual or threatened

                                        5

<PAGE>

          solicitation of proxies or consents by or on behalf of a Person other
          than the Board.

     (i)  "Release Agreement" means an agreement, in substantially the form
          customarily used by the Company for similarly situated executives of
          the Company in similar instances, pursuant to which the Executive
          releases, to the extent permitted by law, all current or future
          claims, known or unknown, arising on or before the date of the release
          against the Company, its subsidiaries and its officers.

     (j)  "Severance Period" means the period of time commencing on the date of
          the first occurrence of a Change in Control and continuing until the
          earlier of (i) the second anniversary of the occurrence of the Change
          in Control, or (ii) the Executive's death.

     (k)  "Subsidiary" means a corporation, company or other entity (i) at least
          50 percent of whose outstanding shares or securities (representing the
          right to vote for the election of directors or other managing
          authority) are, or (ii) which does not have outstanding shares or
          securities (as may be the case in a partnership, joint venture or
          unincorporated association), but at least 50 percent of whose
          ownership interest representing the right generally to make decisions
          for such other entity is, now or hereafter, owned or controlled,
          directly or indirectly, by the Company.

     (l)  "Target Annual Direct Compensation" means the sum of the Executive's
          Base Pay, target annual incentive opportunity, and the annualized
          value of the most recent long-term incentive award approved by the
          Compensation and Organization Committee of the Board. For purposes of
          measuring annualized long-term incentives, the awards shall be
          measured on their date of grant using reasonable assumptions,
          including, but not limited to, fair value principles such as those
          identified in Statement of Financial Accounting Standards No. 123,
          Share-Based Payment; the value of such awards shall be annualized over
          the frequency of their grant. Notwithstanding the foregoing, if, for
          purposes of calculating "Target Annual Direct Compensation," the most
          recent long-term incentive award would be the long-term incentive
          award granted in August 2006 (the "2006 Award"), the calculation of
          "Target Annual Direct Compensation" will include only 50% of the value
          of such 2006 Award.

     (m)  "Term" means the period commencing as of the date hereof and expiring
          on the second anniversary of the date of this Agreement, with
          automatic one-year renewals thereafter unless either party notifies
          the other at least 90 days before the scheduled expiration date that
          the Term is not to renew; provided, however, that (i) if a Change in
          Control occurs during the Term, the Term will expire on, and no sooner
          than, the last day of the Severance Period; and (ii) subject to
          Section 3(c), if, prior to a Change in Control, the Executive ceases
          for any reason to be an officer of the Company or an employee of the
          Company or any Subsidiary, thereupon without further action the Term
          shall be deemed to have expired and this Agreement will immediately
          terminate and be of no further effect. For purposes of this Section
          1(m), the Executive shall not be deemed to have ceased

                                        6

<PAGE>

          to be an employee of the Company and any Subsidiary by reason of the
          transfer of the Executive's employment between the Company and any
          Subsidiary, or among Subsidiaries.

     (n)  "Termination Date" means the date on which the Executive's employment
          is terminated (the effective date of which will be the date of
          termination, or such other date that may be specified by the Executive
          if the termination is pursuant to Section 3(b)).

     (o)  "Voting Stock" means at any time, the then-outstanding securities
          entitled to vote generally in the election of directors of the
          Company.

2.   Operation of Agreement. This Agreement will be effective and binding
     immediately upon its execution, but, anything in this Agreement to the
     contrary notwithstanding, except as provided in Section 3(c), the payments
     and benefits provided under this Agreement will not be payable unless and
     until a Change in Control occurs. Upon the occurrence of a Change in
     Control at any time during the Term, without further action, this Agreement
     will become immediately operative.

3.   Termination Following a Change in Control.

     (a)  If a Change in Control occurs and the Executive's employment is
          terminated by the Company or a Subsidiary during the Severance Period
          (or pursuant to Section 3(c)), the Executive will be entitled to the
          benefits provided by Section 4 unless such termination is the result
          of the occurrence of one or more of the following events:

          (i)  The Executive's death;

          (ii) The Executive's having become unable (as determined by the Board
               in good faith), with or without reasonable accommodations, to
               regularly perform the Executive's duties by reason of illness or
               incapacity; or

          (iii) Cause.

     (b)  In the event of the occurrence of a Change in Control, the Executive
          may terminate employment with the Company and any Subsidiary during
          the Severance Period for Good Reason with the right to severance
          compensation as provided in Section 4 regardless of whether any other
          reason, other than Cause, for such termination exists or has occurred,
          including without limitation other employment.

     (c)  Anything in this Agreement to the contrary notwithstanding, if a
          Change in Control occurs and not more than 90 days prior to the date
          on which the Change in Control occurs, the Executive's employment with
          the Company is terminated by the Company, such termination of
          employment will be deemed to be a termination of employment after a
          Change in Control for purposes of this Agreement and, in addition, the
          Company will be required to pay to the Executive

                                        7

          in a lump sum in cash, the sum of: (1) the difference between the fair
          market value of a common share of the Company and the exercise price
          of each outstanding stock option held by the Executive that was
          forfeited as a result of the Executive's termination of employment
          multiplied by the number of shares underlying each stock option held
          by the Executive that was forfeited as a result of the Executive's
          termination of employment and (2) the fair market value of a common
          share of the Company multiplied by the number of shares underlying
          each share of restricted stock and each performance share and other
          equity award held by the Executive that was forfeited as a result of
          the Executive's termination of employment. For this purpose, the "fair
          market value of a common share of the Company" shall be deemed to be
          the price per share paid in connection with the Change in Control.

     (d)  A termination of employment pursuant to Section 3(a), 3(b) or 3(c)
          will not affect any rights that the Executive may have pursuant to any
          agreement, policy, plan, program or arrangement of the Company or any
          Subsidiary providing employee benefits, which rights will be governed
          by the terms thereof; provided, however, that if upon termination of
          employment, the Executive is entitled to severance compensation or
          benefits under this Agreement and pursuant to any employment or
          severance agreement or employee plan (an "Employment Agreement"), the
          Executive will be entitled to severance benefits under either this
          Agreement or such Employment Agreement, whichever agreement provides
          for greater benefits, but will not be entitled to benefits under both
          agreements.

4.   Severance Compensation.

     (a)  If, following the occurrence of a Change in Control, the Company or a
          Subsidiary of the Company terminates the Executive's employment during
          the Severance Period other than pursuant to Section 3(a)(i), 3(a)(ii)
          or 3(a)(iii), or if the Executive terminates the Executive's
          employment pursuant to Section 3(b), the Company will be obligated to
          make the following payments and provide the following benefits to the
          Executive.

          (i)  The Executive will be entitled to receive: (i) as soon as
               practicable following the end of the Employment Period, any Base
               Pay 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 date of
               termination of the Executive's employment, (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 this Section 4, any severance pay program or policy
               of the Company or a Subsidiary), and (iii) subject to Section
               4(a)(ii) below, payments or benefits payable pursuant to the
               terms of any annual and/or long-term incentive plan of the
               Company or a Subsidiary in

                                        8

<PAGE>

               accordance with the terms thereof. In addition, the Executive
               shall be entitled to the additional benefits and amounts
               described in the succeeding subsections of this Section 4, in the
               circumstances described in such subsections.

          (ii) Within ten (10) business days after the expiration of any
               revocation period relating to the Release Agreement described in
               Section 20 below and in lieu of payments under the terms of the
               Company's annual bonus plan applicable to the Executive, the
               Executive will be entitled to receive a lump sum cash payment in
               an amount equal to the greater of (A) the Executive's target or
               par annual bonus for the fiscal year in which the Termination
               Date occurs or (B) the Executive's target or par annual bonus for
               the fiscal year in which the Change in Control occurs, pro-rated
               for the number of full months that the Executive was employed
               during such fiscal year (i.e., the annual bonus shall be
               multiplied by a fraction, the numerator of which is the number of
               full months during which the Executive was actively employed by
               the Company in the relevant fiscal year and the denominator of
               which is 12).

          (iii) Within ten (10) business days after the expiration of any
               revocation period relating to the Release Agreement described in
               Section 20 below, the Executive will be entitled to receive a
               lump sum cash payment in an amount equal to two (2) times the sum
               of (A) Base Pay (at the highest rate in effect for any period
               within three years prior to the Termination Date), plus (B)
               annual bonus (in an amount equal to the greater of the
               Executive's target or par annual bonus for the year in which the
               Termination Date occurs or for the year in which the Change in
               Control occurs, whichever is greater).

          (iv) For a period of eighteen (18) months following the Termination
               Date (the "Continuation Period"), the Executive will be entitled
               to continued participation in the Company's medical, dental,
               vision, long-term disability and life insurance plans (excluding
               benefits under the executive death benefit plan) (the "Benefit
               Plans"), subject to the terms and conditions of the Benefit
               Plans, including, but not limited to, timely payment of any
               employee contributions necessary to maintain participation;
               provided, however, that (A) such coverage shall be provided only
               to the extent that such coverage would not be considered
               "deferred compensation" subject to the requirements of Section
               409A of the Code; and (B) the Executive's continued participation
               in the Benefit Plans during the Continuation Period shall satisfy
               the Benefit Plans' obligation, if any, to provide the Executive
               the right to continuation coverage under the Benefit Plans
               pursuant to the Consolidated Omnibus Budget Reconciliation Act of
               1986, as amended. If any benefit described in this Section
               4(a)(iv) 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

                                        9

<PAGE>

               (including any income or social security tax) imposed on the
               benefits described in this Section 4(a)(iv) and any such
               additional payment by the Company, the recipient retains an
               amount equal to such taxes. Notwithstanding the foregoing, if the
               Company determines that the provision of benefits under this
               Section 4(a)(iv) would be likely to result in negative tax
               consequences to the Executive, the Company will use its
               reasonable best efforts to make other arrangements to provide a
               substantially similar benefit to the Executive that does not have
               such negative tax consequences, which may include, making a lump
               sum payment at the earliest time permitted under Section 409A of
               the Code, in an amount equal to the Company's reasonable
               determination of the present value of any such benefits that, if
               provided, would result in negative tax consequences to the
               Executive and/or providing such benefit through insurance
               coverage on the Executive's behalf.

          (v)  Within ten (10) business days after the expiration of any
               revocation period relating to the Release Agreement described in
               Section 20 below, the Executive will be entitled to receive a
               lump sum cash payment in an amount equal to the present value of
               continued participation in the Benefit Plans for an additional
               six (6) months. If any benefit described in this Section 4(a)(v)
               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 (including any income or social security tax) imposed
               on the benefits described in this Section 4(a)(v) and any such
               additional payment by the Company, the recipient retains an
               amount equal to such taxes.

          (vi) 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 cash payment, within
               five (5) business days after the expiration of any revocation
               period relating to the Release Agreement described in Section 20
               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 4(a)(vi) 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

                                       10

<PAGE>

               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.

          (vii) 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.

     (b)  Notwithstanding anything to the contrary contained in this Section 4,
          if any payment to the Executive under this Section 4 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 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 4 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.

     (c)  Without limiting the rights of the Executive at law or in equity, if
          the Company fails to make any payment or provide any benefit required
          to be made or provided hereunder on a timely basis, the Company will
          pay interest on the amount or value thereof at an annualized rate of
          interest equal to the "prime rate" as set forth from time to time
          during the relevant period in The Wall Street Journal "Money Rates"
          column. Such interest will be payable as it accrues on demand. Any
          change in such prime rate will be effective on and as of the date of
          such change.

5.   Golden Parachute Excise Tax. The amounts payable to the Executive under
     Section 4 shall be adjusted as set forth in this Section 5 if the sum (the
     "combined amount") of the amounts payable under Section 4 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, 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

                                       11

<PAGE>

     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 5, the Gross-Up
     Payment shall be made on the date the lump sum payments provided in Section
     4 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 4, 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 5 is 10% or more of the combined amount,
     the intention of the preceding sentences in this Section 5 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 5, Gross-Up Payments, including any additional
     payment made subsequent to any payment under Section 4, 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.

6.   No Mitigation Obligation. The Company hereby acknowledges that it will be
     difficult and may be impossible for the Executive to find reasonably
     comparable employment following the Termination Date. Accordingly, the
     payment of the severance compensation by the Company to the Executive in
     accordance with the terms of this Agreement is hereby acknowledged by the
     Company to be reasonable, and the Executive will not be required to
     mitigate the amount of any payment provided for in this Agreement by
     seeking other employment or otherwise, nor will any profits, income,
     earnings or other benefits from any source whatsoever create any
     mitigation, offset, reduction or any other obligation on the part of the
     Executive hereunder or otherwise.

7.   Legal Fees and Expenses.

     (a)  If it should appear to the Executive that the Company has failed to
          comply with any of its obligations under this Agreement or in the
          event that the Company or any other person takes or threatens to take
          any action to declare this Agreement void or unenforceable, or
          institutes any proceeding designed to deny, or to recover from, the
          Executive the benefits provided or intended to be provided to the
          Executive hereunder, the Company irrevocably authorizes the Executive
          from time to time to retain counsel of the Executive's choice, at the
          expense of the Company as hereafter provided, to advise and represent
          the Executive in connection with any such dispute or proceeding.
          Without respect to whether the Executive prevails, in whole or in
          part, in connection with any of the foregoing, the Company will pay
          and be financially responsible for reasonable attorneys' and

                                       12

<PAGE>

          related fees and expenses incurred by the Executive in connection with
          claims made in good faith but only if, and to the extent and at the
          earliest date(s) that, such actions are determined to be permitted
          without violating Section 409A of the Code. Such payments will be made
          after delivery of the Executive's written requests for payment,
          accompanied by such evidence of fees and expenses incurred as the
          Company may reasonably require.

     (b)  Without limiting the obligations of the Company pursuant to Section
          7(a), in the event that (i) the Executive is entitled to benefits
          hereunder and (ii) payments to the Executive would be required to be
          delayed by more than 20 business days due to Section 409A of the Code
          or otherwise, the performance of the Company's obligations under
          Section 4 and this Section 7 will be secured by amounts deposited or
          to be deposited in a grantor trust pursuant to certain trust
          agreements to which the Company will be a party providing that the
          benefits to be paid pursuant to Section 4 and the reasonable fees and
          expenses of counsel selected from time to time by the Executive
          pursuant to Section 7(a) will be paid, or reimbursed to the Executive
          if paid by the Executive, either in accordance with the terms of such
          trust agreements, or, if not so provided, on a regular, periodic basis
          upon presentation by the Executive to the trustee of a statement or
          statements prepared by such counsel in accordance with its customary
          practices. Any failure by the Company to satisfy any of its
          obligations under this Section 7(b) will not limit the rights of the
          Executive hereunder. Subject to the foregoing, the Executive will have
          the status of a general unsecured creditor of the Company and will
          have no right to, or security interest in, any assets of the Company
          or any Subsidiary.

8.   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 Executive's employment, 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 8(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
          Executive's employment and not compete with the Company for a
          reasonable period thereafter, as further provided in the following
          subsections.

     (b)  Covenants During Employment. During the Executive's employment, the
          Executive will not compete with the Company anywhere that the Company
          conducts its business. In accordance with this restriction, but
          without limiting its terms, during the Executive's employment, the
          Executive will not:

                                       13

<PAGE>

          (i)  enter into or engage in any business which competes with the
               business of the Company;

          (ii) solicit customers, business, patronage or orders for, or sell,
               any products and services in competition with, or for any
               business that competes with, the business of the Company;

          (iii) divert, entice or otherwise take away any customers, business,
               patronage or orders of the Company 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 business of the Company.

     (c)  Covenants Following Termination. If, during the Severance Period, the
          Executive's employment is terminated entitling the Executive to
          payments and benefits under Section 4 of this Agreement, for a period
          of one (1) year following the termination of the Executive's
          employment, 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 8(b) and 8(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 8, the Company shall include
          any and all Subsidiaries.

     (f)  The Company's Business. For the purposes of Sections 8(b), 8(c), 8(j)
          and 8(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 that
          the Company may enter, as further described in any and 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 8(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 two (2) 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

     (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

                                       15

<PAGE>

               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 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 8(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.

                                       16

          (ii) 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 recognize the Company as the copyright owner, will contain
               all proper copyright notices, e.g., "(creation date) USG
               Corporation, 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 one (1) year 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)  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 8(b), 8(c),
          8(h), 8(i), 8(j) and 8(k) of this Agreement, without the necessity of
          proof of actual damage.

     (m)  Reasonableness. The Executive acknowledges that the Executive's
          obligations under this Section 8 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.

9.   Employment Rights. Nothing expressed or implied in this Agreement will
     create any right or duty on the part of the Company or the Executive to
     have the Executive remain in the employment of the Company or any
     Subsidiary prior to or following any Change in Control.

                                       17

10.  Withholding of Taxes. The Company may withhold from any amounts payable
     under this Agreement all federal, state, city or other taxes as the Company
     is required to withhold pursuant to any applicable law, regulation or
     ruling.

11.  Successors and Binding Agreement.

     (a)  The Company will require any successor (whether direct or indirect, by
          purchase, merger, consolidation, reorganization or otherwise) to all
          or substantially all of the business or assets of the Company, by
          agreement in form and substance reasonably satisfactory to the
          Executive, expressly to assume and agree to perform this Agreement in
          the same manner and to the same extent the Company would be required
          to perform if no such succession had taken place. This Agreement will
          be binding upon and inure to the benefit of the Company and any
          successor to the Company, including without limitation any persons
          acquiring directly or indirectly all or substantially all of the
          business or assets of the Company whether by purchase, merger,
          consolidation, reorganization or otherwise (and such successor will
          thereafter be deemed the "Company" for the purposes of this
          Agreement), but will not otherwise be assignable, transferable or
          delegable by the Company.

     (b)  This Agreement will inure to the benefit of and be enforceable by the
          Executive's personal or legal representatives, executors,
          administrators, successors, heirs, distributees and legatees.

     (c)  This Agreement is personal in nature and neither of the parties hereto
          will, without the consent of the other, assign, transfer or delegate
          this Agreement or any rights or obligations hereunder except as
          expressly provided in Sections 11(a) and 11(b). Without limiting the
          generality or effect of the foregoing, the Executive's right to
          receive payments hereunder will not be assignable, transferable or
          delegable, whether by pledge, creation of a security interest, or
          otherwise, other than by a transfer by the Executive's will or by the
          laws of descent and distribution and, in the event of any attempted
          assignment or transfer contrary to this Section 11(c), the Company
          will have no liability to pay any amount so attempted to be assigned,
          transferred or delegated.

12.  Notices. For all purposes of this Agreement, all communications, including
     without limitation notices, consents, requests or approvals, required or
     permitted to be given hereunder will be in writing and will be deemed to
     have been duly given when hand delivered or dispatched by electronic
     facsimile transmission (with receipt thereof orally confirmed), or five
     business days after having been mailed by United States registered or
     certified mail, return receipt requested, postage prepaid, or three
     business days after having been sent by a nationally recognized overnight
     courier service such as FedEx or UPS, addressed to the Company (to the
     attention of the Secretary of the Company) at its principal executive
     office and to the Executive at the Executive's principal residence, or to
     such other address as any party may have furnished to the other in writing
     and in accordance herewith, except that notices of changes of address will
     be effective only upon receipt.

13.  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.

14.  Validity. If any provision of this Agreement or the application of any
     provision hereof to any person or circumstance is held invalid or otherwise
     unenforceable, the remainder of this Agreement and the application of such
     provision to any other person or circumstance will not be affected, and the
     provision so held to be invalid or otherwise unenforceable will be reformed
     to the extent (and only to the extent) necessary to make it enforceable or
     valid.

15.  Miscellaneous.

     (a)  No provision of this Agreement may be modified, waived or discharged
          unless such waiver, modification or discharge is agreed to in writing
          signed by the Executive and the Company. No waiver by either party
          hereto at any time of any breach by the other party hereto or
          compliance with any condition or provision of this Agreement to be
          performed by such other party will be deemed a waiver of similar or
          dissimilar provisions or conditions at the same or at any prior or
          subsequent time. No agreements or representations, oral or otherwise,
          expressed or implied with respect to the subject matter hereof have
          been made by either party that are not set forth expressly in this
          Agreement.

     (b)  Subject to Section 3(d), this Agreement supersedes, as of the date
          first above written, any prior agreements providing for severance
          payments and benefits following a Change in Control, including the
          Termination Compensation Agreement, between the Executive and the
          Company (the "Prior Agreements"). The Executive agrees that he or she
          has no further rights under the Prior Agreements.

     (c)  The headings used in this Agreement are intended for convenience or
          reference only and will not in any manner amplify, limit, modify or
          otherwise be used in the construction or interpretation of any
          provision of this Agreement. References to Sections are to Sections of
          this Agreement. Any reference in this Agreement to a provision of a
          statute, rule or regulation will also include any successor provision
          thereto.

                                       19

<PAGE>

16.  Severability. Whenever possible, each provision of this Agreement shall be
     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.

17.  Survival. Notwithstanding any provision of this Agreement to the contrary,
     the parties' respective rights and obligations under Sections 3(d), 4, 5,
     7, 8, 10, 11(b), 16 and 17 will survive any termination or expiration of
     this Agreement or the termination of the Executive's employment following a
     Change in Control for any reason whatsoever.

18.  Beneficiaries. The Executive will be entitled to select (and change, to the
     extent permitted under any applicable law) a beneficiary or beneficiaries
     to receive any compensation or benefit payable hereunder following the
     Executive's death, and may change such election, in either case by giving
     the Company written notice thereof in accordance with Section 12. In the
     event of the Executive's death or a judicial determination of the
     Executive's incompetence, reference in this Agreement to the "Executive"
     will be deemed, where appropriate, to the Executive's beneficiary, estate
     or other legal representative.

19.  Counterparts. This Agreement may be executed in one or more counterparts,
     each of which will be deemed to be an original but all of which together
     will constitute one and the same agreement.

20.  Release Agreement. No payments shall be made under Section 4 hereof if the
     Executive declines to sign and return a Release Agreement or revokes such
     Release Agreement within the time provided therein. If the Executive
     becomes entitled to payments under Section 4 hereof, the Company shall
     deliver to the Executive a copy of the Company's standard form of Release
     Agreement within ten (10) business days of the Executive's Termination
     Date.

21.  Representations. The Executive represents and warrants to the Company that
     upon the execution and delivery of this Agreement by the Company, this
     Agreement shall be the valid and binding obligation of the Executive,
     enforceable in accordance with its terms. The Company represents and
     warrants to the Executive that upon the execution and delivery of this
     Agreement by the Executive, this Agreement shall be the valid and binding
     obligation of the Company, enforceable in accordance with its terms.

                                       20

22.  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.
