                                 USG CORPORATION
                           STOCK COMPENSATION PROGRAM
                           FOR NON-EMPLOYEE DIRECTORS
                            (as amended and restated)



Article 1.        Establishment, Purpose, and Duration

         1.1 Establishment of the Plan. USG Corporation,  a Delaware corporation
(the "Corporation"), hereby amends and restates in its entirety the non-employee
director  incentive stock  compensation plan known as the "USG Corporation Stock
Compensation  Program for  Non-Employee  Directors"  (herein,  as so amended and
restated,  called the "Plan"), as set forth in this document.  The Plan provides
for the annual grant of shares of the common stock of the Corporation ("Shares")
to  non-employee  directors and for the  acquisition of Deferred Stock Units (as
herein defined) by non-employee  directors,  subject to the terms and provisions
set forth herein.

         Upon  approval by the Board of Directors of the  Corporation,  the Plan
shall become  effective  as of July 1, 1997 (the  "Effective  Date"),  and shall
remain in effect as provided in Section 1.3 herein.

         The  Plan  is  intended  as  a  replacement  for  certain  compensation
arrangements for  non-employee  directors in effect prior to the Effective Date,
including  the  Plan  prior  to  this   amendment  and   restatement,   and  the
Corporation's Directors' Deferred Fee Plan (collectively, the "Prior Programs").
The Prior  Programs  will  continue to apply in the future only with  respect to
applicable  compensation earned by non-employee directors for periods of service
prior to July 1, 1997.

         1.2.  Purpose of the Plan.  The  purpose of the Plan is to promote  the
achievement of long-term  objectives of the  Corporation by linking the personal
interests of non-employee  directors to those of the Corporation's  stockholders
and to attract and retain non-employee directors of outstanding competence.

         1.3 Duration of the Plan.  The Plan will  commence as of the  Effective
Date and shall  remain in effect  until  terminated  or  amended by the Board of
Directors pursuant to Article 9.


Article 2.        Definitions

         In  addition to the terms  defined in the Plan,  these terms shall have
the meanings set forth below:

         (a)      "Deferred  Stock Unit" or "Unit" means an award  acquired by a
                  Participant as a measure of participation  under the Plan, and
                  having a value which changes in direct  relation to changes in
                  the  value  in  the  relevant  number  of  Shares  during  the
                  applicable period.

         (b)      "Fair  Market  Value" shall equal the mean of the high and low
                  sales prices of a Share on The New York Stock  Exchange on the
                  relevant date, or, if there were no sales on such date, on the
                  last trading date preceding the relevant date.


Article 3.        Administration

         3.1 The Committee on Directors.  The Plan shall be  administered by the
Committee  on  Directors  (the  "Committee")  of the Board of  Directors  of the
Corporation, subject to the restrictions set forth in the plan.

         3.2 Administration by the Committee.  The Committee shall have the full
power,  discretion,  and  authority to interpret  and  administer  the Plan in a
manner which is consistent  with the Plan's  provisions.  In no event,  however,
shall  the  Committee  have  the  power to  determine  Plan  eligibility,  or to
determine the number,  the value, the vesting period, or the timing of awards to
be made under the Plan (all such determinations  being automatic pursuant to the
provisions of the Plan).

         3.3 Decisions  Binding.  All  determinations  and decisions made by the
Committee  pursuant to the Plan,  and all related  orders or  resolutions of the
Committee shall be final, conclusive,  and binding on all persons, including the
Corporation, its shareholders,  employees,  directors,  Participants,  and their
estates and beneficiaries.


Article 4.        Participation.


         4.1  Participation.  Persons  eligible to  participate  in the Plan are
limited to  non-employee  directors  who are serving on the Board on the date of
each scheduled award under the Plan ("Participants").


Article 5.        Annual Equity Grants for Participants.

         5.1 Annual Equity Grants.  Commencing  July 1, 1998,  each  Participant
shall receive an annual equity grant of five hundred (500) Shares on July 1 each
year, or a proportionate  share of such grant based on full months of service as
a non-employee  director  since the prior July 1. In lieu of issuing  fractional
Shares, the Corporation shall round up to the nearest full Share.

         5.2 Timing of Payout.  Certificates for Shares awarded pursuant to this
Article 5 shall be issued as soon as administratively practicable following July
1 each year.

         5.3 Deferral  Election.  In lieu of receiving  his or her annual equity
grant in Shares,  any  Participant  may elect to receive all or a portion of any
such grant in the form of Deferred Stock Units.  Any such election shall be made
pursuant to Article 7.

         5.4 Biennial  Review.  The Committee shall conduct a biennial review of
the appropriateness of the annual equity awards granted pursuant to this Article
5. In the event the  Committee  determines  that an  adjustment in the amount of
equity awards  pursuant to this Article 5 is  appropriate,  the Committee  shall
make a recommendation to the Board for an appropriate amendment.


Article 6.        Retainer Share Payments

         6.1 Portion of Retainers Paid in Shares.  During the term of this Plan,
each Participant  shall receive  twenty-five  percent (25%) of his or her annual
retainer for board  service in the form of Shares,  payable as the third quarter
installment of such annual retainer.

         6.2 Number of Shares Paid.  The number of Shares to be issued  pursuant
to Section 6.1 will be  determined  on September  25th of each year (or the next
trading  date if such date is not a date on which  shares  are traded on The New
York Stock  Exchange),  and shall equal  twenty-five  percent  (25%) of the then
current annual retainer for board service, divided by the Fair Market Value of a
Share on such date. In lieu of issuing  fractional Shares, the Corporation shall
round up to the nearest full share.

         6.3 Timing of Payout.  Certificates for Shares payable pursuant to this
Article 6 shall be issued as soon as administratively  practicable following the
conclusion of the third calendar quarter.


Article 7.        Annual Deferral Opportunity

         7.1  Termination of Prior  Programs;  Deferral of Retainers and Meeting
Fees. The Prior Programs are hereby terminated. In lieu thereof, any Participant
may elect  during the term of this Plan to receive  all or a portion of the cash
component of his or her annual retainer or meeting fees for board service in the
form of Deferred Stock Units. Any Participant may also elect to receive all or a
portion of his or her annual equity grant awarded pursuant to Section 5.1 in the
form of Deferred Stock Units. Elections to receive Deferred Stock Units shall be
irrevocable and shall be subject to the provisions of this Article 7 and Article
8.

         7.2 Annual Deferral Election.  Any election to receive all or a portion
of the cash component of a Participant's annual retainer, meeting fees or annual
equity grant in the form of Deferred Stock Units shall be made by December 1 for
all payments to be made in the succeeding  calendar year.  Each new  Participant
shall make his or her election  upon election to the Board.  Deferral  elections
may only be made in ten percent (10%) increments.

         7.3 Number of Deferred Stock Units.  The number of Deferred Stock Units
to be granted in connection with an election pursuant to Section 7.2 shall equal
(x) the number of Shares being  deferred,  in the case of annual equity  grants,
and (y) the dollar value of the portion of the annual  retainer and meeting fees
being  deferred,  divided by the Fair Market Value of a Share on the last day of
the applicable quarter, in the case of installments of annual retainers,  or the
applicable meeting date, in the case of meeting fees.

         7.4 Vesting of Deferred Stock Units. Subject to the terms of this Plan,
all  Deferred  Stock  Units  acquired  under this  Article 7 shall vest upon the
acquisition of such Deferred Stock Units.


Article 8.        Deferred Stock Units

         8.1 Value of Deferred Stock Units.  Each Deferred Stock Unit shall have
a value  that is  equal  to the Fair  Market  Value  of a Share on the  relevant
valuation  date, it being  understood that subsequent to the date of an award or
acquisition  of a  Deferred  Stock  Unit,  its  value  shall  change  in  direct
relationship to changes in the Fair Market Value of a Share.

         8.2  Dividend  Equivalents.  Dividend  equivalents  shall be  earned on
Deferred  Stock Units  provided  under this Plan and shall be converted  into an
equivalent  amount of  Deferred  Stock  Units based upon the value of a Deferred
Stock Unit on the payment date of the related dividend.  The converted  Deferred
Stock Units will be fully vested upon conversion.

         8.3 Timing and Amount of Payout.  Except as provided  otherwise  in the
Plan,  the amount payable to a Participant  shall be the aggregate  value of the
Participant's  vested  Deferred  Stock  Units,  if any,  on the  date  that  the
Participant terminates his or her service on the Board, normally payable in cash
in a lump sum within thirty (30) days following the Participant's termination of
service on the Board. In lieu of a lump sum payment, a Participant may elect, in
a  writing  filed  with the  Corporate  Secretary  of the  Corporation  prior to
termination  of his or her Board service,  to receive  payment of such amount in
cash in two installments. The first installment, equal to fifty percent (50%) of
such amount,  shall be made within thirty (30) days following the  Participant's
termination of service on the Board. The second installment,  including interest
credited at the prime  interest  rate of The First  National  Bank of Chicago in
effect on the date of such  termination,  shall be made one year after the first
installment.

         8.4 Deferred  Stock Unit  Account.  A Deferred  Stock Unit Account (the
"Account")  shall be  established  and  maintained by the  Corporation  for each
Participant  receiving Deferred Stock Units under the Plan. As the value of each
Deferred Stock Unit changes pursuant to Section 8.1, the Account  established on
behalf of each Participant shall be adjusted accordingly.  Each Account shall be
the record of the Deferred Stock Units granted to the Participant  under Article
7 of the Plan, shall be maintained solely for accounting purposes, and shall not
require a segregation of any Corporation assets.

         8.5 Annual  Reports.  Participants  with  Deferred  Stock  Units  shall
receive annual reports providing  detailed  information about their Accounts and
changes in their Accounts during the preceding year.


Article 9.        Amendment, Modification, and Termination

         9.1 Amendment,  Modification, and Termination. The Board may terminate,
amend, or modify the Plan at any time and from time to time.

         9.2 Awards Previously Granted.  Unless required by law, no termination,
amendment,  or modification  of the Plan shall in any material manner  adversely
affect any award previously provided under the Plan, without the written consent
of the Participant holding such award.


Article 10.       Miscellaneous

         10.1 Severability. In the event any provision of the Plan shall be held
illegal or invalid for any reason, the illegality or invalidity shall not affect
the remaining parts of the Plan, and the Plan shall be construed and enforced as
if the illegal or invalid provision had not been included.

         10.2 Benefit Transfers. The interests of any Participant or beneficiary
entitled to payments hereunder shall not be subject to attachment or garnishment
or other legal process by any creditor of any such  Participant  or  beneficiary
nor shall  any such  Participant  or  beneficiary  have any  right to  alienate,
anticipate,  commute,  pledge, encumber, or assign any of the benefits or rights
which he or she may expect to receive, contingently or otherwise under this Plan
except as may be  required by the tax  withholding  provisions  of the  Internal
Revenue Code of 1986  ("Code") or of a state's  income tax act.  Notwithstanding
the foregoing,  amounts  payable with respect to a Participant  hereunder may be
paid as follows:

         (a)      Payments  with respect to a disabled or  incapacitated  person
                  may be paid to such  person's  legal  representative  for such
                  person's  benefit,  to a custodian  under the Uniform Gifts or
                  Transfers  to Minors  Act of any state,  or to a  relative  or
                  friend of such person for such person's benefit; and

         (b)      Transfers by the  Participant  to a grantor trust  established
                  pursuant to Sections 674, 675, 676 and 677 of the Code for the
                  benefit  of the  participant  or a person or  persons  who are
                  members of his or her immediate  family (or for the benefit of
                  their  descendants)  shall be  recognized  and  given  effect,
                  provided that any such transfer has not been disclaimed  prior
                  to the payment, and the trustee of such trust certifies to the
                  Committee that such transfer  occurred  without any payment of
                  consideration for such transfer.

         10.3 Beneficiary Designation. Each Participant under the Plan may, from
time  to  time,  name  any  beneficiary  or  beneficiaries  (who  may  be  named
contingently or  successively)  to whom any benefit under the Plan is to be paid
in the  event of his or her  death.  Each  designation  will  revoke  all  prior
designations by the same Participant, shall be in a form as provided in Appendix
A hereto,  and will be effective  only when filed by the  Participant in writing
with the Corporate Secretary of the Corporation,  acting on behalf of the Board,
during his or her  lifetime.  In the absence of any such  designation,  benefits
remaining unpaid at the  Participant's  death shall be paid to the Participant's
estate.

         10.4 No Right of  Nomination.  Nothing  in this Plan shall be deemed to
create any  obligation  on the part of the Board to nominate  any  director  for
reelection by the Corporation's shareholders.


         10.5  Shares  Available.  The  Shares  delivered  under the Plan may be
either  treasury  shares,  originally  issued  Shares,  or Shares that have been
reacquired by the Corporation, including shares purchased in the open market.

         10.6 Stock  Splits/Stock  Dividends.  In the event of any change in the
outstanding   Shares  of  the   Company   by   reason   of  a  stock   dividend,
recapitalization,  merger,  consolidation,  split-up,  combination,  exchange of
Shares,  or the like,  the aggregate  number of and class of Shares and Deferred
Stock Units awarded  hereunder may be  appropriately  adjusted by the Committee,
whose determination shall be conclusive.

         10.7 Successors. All obligations of the Corporation under the Plan with
respect to awards  granted  hereunder  shall be binding on any  successor to the
Corporation,  whether the existence of such  successor is the result of a direct
or  indirect  purchase,   merger,   consolidation,   or  otherwise,  of  all  or
substantially all of the business and/or assets of the Corporation.

         10.8  Requirements  of Law. The granting of awards under the Plan shall
be subject to all applicable laws, rules, and regulations, and to such approvals
by  any  governmental  agencies  or  national  securities  exchanges  as  may be
required.

         10.9  Governing  Law. The Plan, and all agreements hereunder,  shall be
construed in accordance with and governed by the laws of the State of Delaware.

FOR NON-EMPLOYEE DIRECTORS BENEFICIARY FORM TO:   DEAN H. GOOSSEN, CORPORATE
SECRETARY.





              EXECUTIVE SUMMARY OF KEY ELEMENTS: STOCK COMPENSATION
                       PROGRAM FOR NON-EMPLOYEE DIRECTORS


         I.       Annual Grant of Stock

                  An annual grant,  presently set at 500 shares,  will be issued
                  each July 1st to non-employee directors in service at the time
                  of the grant.  Those  directors  who have  served less than 12
                  full months,  counted from the prior July 1st,  will receive a
                  pro-rated  grant as provided by the Plan.  Directors will have
                  the option of  deferring  all or a portion of the annual grant
                  by conversion  of the deferred  portion into  "deferred  stock
                  units" on a one  Share/one  unit basis.  Deferred  share units
                  will fluctuate in value and become taxable as described in III
                  below  and be  paid  out in  cash as  described  in IV  below.
                  Portions of the annual grant not converted into deferred stock
                  units  become  taxable  compensation  at the time the grant is
                  issued.

         II.      Annual Retainer

                  The current annual retainer is $26,000. The new Plan continues
                  the requirement  that  one-quarter of this retainer be paid in
                  the  form  of  USG  Shares,   payable  as  the  third  quarter
                  installment.   These  shares  are  delivered  as  soon  as  is
                  practical  following the  September  25th  valuation  date. No
                  deferral of these shares is  permitted  and they thus become a
                  taxable compensation item at the time of their delivery.

         III.     Annual Deferral Opportunities

                  The  remainder  of the annual  retainer as well as all meeting
                  and  committee  fees are paid in cash but may be deferred,  in
                  part or in whole (in 10% increments) upon your election.  If a
                  deferral   election   is  made,   the   portion  of  the  cash
                  compensation  so deferred will be converted to "deferred stock
                  units"  whose  initial  value will be  equivalent  to the cash
                  compensation   deferred.   These  deferred  stock  units  will
                  fluctuate  in  value  exactly  as  the  value  of a USG  Share
                  fluctuates. In addition, your deferred stock unit account will
                  be  credited  with  dividend  equivalents.   Any  compensation
                  deferred  under this plan will not be taxable  until  actually
                  paid out (subsequent to retirement).

         IV.      Timing of Deferred Stock Unit Account Pay-out

                  Your Deferred  Stock Unit account  balance will be paid out in
                  cash in a lump  sum  within  thirty  days  of your  retirement
                  unless you elect in writing  to  receive  your  payment in two
                  installments.  If the installment method is elected, the first
                  installment equal to fifty percent of such amount will be paid
                  within  thirty days of the date of  retirement  and the second
                  installment one year later.  During the intervening  year your
                  remaining  account  balance will be credited  with earnings at
                  the prime rate of The First National Bank of Chicago. You will
                  have a taxable event upon each payout.
