Item 5.  Other Events

On March 27, 1998,  the Board of Directors of USG  Corporation  (the  "Company")
declared a dividend of one preferred  share  purchase right (a "Right") for each
outstanding  share of common  stock,  par value  $0.10  per share  (the  "Common
Shares"),  of the Company,  and voted to redeem the outstanding  preferred share
purchase  rights ("Old Rights") at the redemption  price of $0.01 per Old Right.
The Rights dividend and Old Rights redemption both are payable on May 1, 1998 to
the  stockholders  of record on April 15, 1998 (the "Record  Date").  Each Right
entitles the registered holder to purchase from the Company one one-hundredth of
a share of  Junior  Participating  Preferred  Stock,  Series D, par value $1 per
share  (the  "Preferred  Shares"),  of the  Company  at a price  of $200 per one
one-hundredth  of  a  Preferred  Share  (the  "Purchase   Price"),   subject  to
adjustment.  The  description  and terms of the Rights are set forth in a Rights
Agreement dated March 27, 1998 (the "Rights Agreement"), between the Company and
Harris Trust and Savings Bank, as Rights Agent (the "Rights Agent").

Until the  earlier to occur of 10 days  following a public  announcement  that a
person or group of affiliated or associated persons (an "Acquiring Person") have
acquired beneficial ownership of 15% or more of the outstanding Common Shares or
(ii) 10 business  days (or such later date as may be determined by action of the
Board of Directors  prior to such time as any person or group of  affiliated  or
associated  persons becomes an Acquiring  Person) following the commencement of,
or  announcement  of an intention to make, a tender offer or exchange  offer the
consummation  of which would result in the  beneficial  ownership by a person or
group of 15% or more of the outstanding Common Shares (the earlier of such dates
being  called the  "Distribution  Date"),  the Rights  will be  evidenced,  with
respect to any of the Common  Share  certificates  outstanding  as of the Record
Date, by such Common Share  certificates.  The Rights  Agreement  provides that,
until the Distribution  Date (or earlier  redemption,  exchange or expiration of
the  Rights),  the  Rights  will be  transferred  with and only with the  Common
Shares.  Until  the  Distribution  Date  (or  earlier  redemption,  exchange  or
expiration of the Rights), new Common Share certificates issued after the Record
Date upon  transfer  or new  issuance of Common  Shares will  contain a notation
incorporating the Rights Agreement by reference. Until the Distribution Date (or
earlier  redemption,  exchange or expiration  of the Rights),  the surrender for
transfer of any  certificates  for Common  Shares  outstanding  as of the Record
Date,  even  without such  notation,  will also  constitute  the transfer of the
Rights  associated with the Common Shares  represented by such  certificate.  As
soon as  practicable  following the  Distribution  Date,  separate  certificates
evidencing the Rights ("Right Certificates") will be mailed to holders of record
of the Common  Shares as of the close of business on the  Distribution  Date and
such separate Right Certificates alone will evidence the Rights.

The Rights are not exercisable until the Distribution Date. The Rights
will expire on March 27, 2008 (the "Final  Expiration  Date"),  unless the Final
Expiration  Date is  extended  or unless  the  Rights are  earlier  redeemed  or
exchanged by the Company, in each case as described below.

The  Purchase  Price  payable,  and the  number  of  Preferred  Shares  or other
securities  or  property  issuable,  upon  exercise of the Rights are subject to
adjustment  from  time to time  to  prevent  dilution  in the  event  of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or  warrants  to  subscribe  for or  purchase  Preferred  Shares at a price,  or
securities  convertible into Preferred Shares with a conversion price, less than
the  then-current  market  price of the  Preferred  Shares,  or  (iii)  upon the
distribution to holders of the Preferred  Shares of evidences of indebtedness or
assets  (excluding  regular  periodic  cash  dividends  paid out of  earnings or
retained  earnings or dividends  payable in Preferred Shares) or of subscription
rights or warrants (other than those referred to above).

The  number of  outstanding  Rights and the  number of one  one-hundredths  of a
Preferred  Share  issuable  upon  exercise  of each  Right are also  subject  to
adjustment  in the  event  of a stock  split  of the  Common  Shares  or a stock
dividend  on the  Common  Shares  payable  in  Common  Shares  or  subdivisions,
consolidations or combinations of the Common Shares occurring, in any such case,
prior to the Distribution Date.

Preferred Shares purchasable upon exercise of the Rights will not be redeemable.
Each  Preferred  Share  will be  entitled  to a minimum  preferential  quarterly
dividend payment of $25 per share but will be entitled to an aggregate  dividend
of  100  times  the  dividend  declared  per  Common  Share.  In  the  event  of
liquidation,  the holders of the Preferred  Shares will be entitled to a minimum
preferential  liquidation  payment of $100 per share but will be  entitled to an
aggregate payment of 100 times the payment made per Common Share. Each Preferred
Share will have 100 votes,  voting together with the Common Shares.  Finally, in
the event of any merger,  consolidation  or other  transaction  in which  Common
Shares are exchanged, each Preferred Share will be entitled to receive 100 times
the amount  received per Common  Share.  These rights are protected by customary
anti-dilution provisions.

Because of the nature of the Preferred Shares' dividend,  liquidation and voting
rights,  the  value  of the one  one-hundredth  interest  in a  Preferred  Share
purchasable  upon  exercise of each Right  should  approximate  the value of one
Common Share.

In the  event  that  the  Company  is  acquired  in a merger  or other  business
combination  transaction  or 50% or more of its  consolidated  assets or earning
power are sold after a person or group has become an  Acquiring  Person,  proper
provision will be made so that each holder of a Right will  thereafter  have the
right to receive,  upon the exercise  thereof at the then current exercise price
of the Right,  that number of shares of common  stock of the  acquiring  company
which at the time of such  transaction will have a market value of two times the
exercise price of the Right. In the event that any person or group of affiliated
or associated  persons becomes an Acquiring  Person,  proper  provision shall be
made so that each holder of a Right, other than Rights beneficially owned by the
Acquiring Person (which will thereafter be void), will thereafter have the right
to receive upon  exercise  that number of Common Shares having a market value of
two times the exercise price of the Right.

At any time after any person or group  becomes an Acquiring  Person and prior to
the acquisition by such person or group of 50% or more of the outstanding Common
Shares,  the Board of Directors  of the Company may  exchange the Rights  (other
than Rights owned by such person or group which will have become void), in whole
or in part, at an exchange ratio of one Common Share, or one  one-hundredth of a
Preferred  Share (or of a share of a class or series of the Company's  preferred
stock having equivalent rights, preferences and privileges),  per Right (subject
to adjustment).

With certain  exceptions,  no adjustment in the Purchase  Price will be required
until  cumulative  adjustments  require  an  adjustment  of at  least 1% in such
Purchase  Price.  No  fractional  Preferred  Shares  will be issued  (other than
fractions  which are  integral  multiples  of one  one-hundredth  of a Preferred
Share,  which may, at the  election of the Company,  be evidenced by  depositary
receipts) and in lieu  thereof,  an adjustment in cash will be made based on the
market price of the  Preferred  Shares on the last trading day prior to the date
of exercise.

At any time  prior to the  acquisition  by a person  or group of  affiliated  or
associated  persons of  beneficial  ownership of 15% or more of the  outstanding
Common  Shares,  the Board of  Directors of the Company may redeem the Rights in
whole, but not in part, at a price of $.01 per Right (the  "Redemption  Price").
The  redemption of the Rights may be made  effective at such time, on such basis
and with such  conditions as the Board of Directors in its sole  discretion  may
establish.  Immediately upon any redemption of the Rights, the right to exercise
the Rights will terminate and the only right of the holders of Rights will be to
receive the Redemption Price.

The terms of the Rights may be amended by the Board of  Directors of the Company
without  the consent of the holders of the Rights,  including  an  amendment  to
lower certain thresholds described above to not less than the greater of the sum
of .001% and the largest  percentage of the outstanding Common Shares then known
to the Company to be beneficially  owned by any person or group of affiliated or
associated  persons  and (ii) 10%,  except  that from and after such time as any
person or group of affiliated or associated  persons becomes an Acquiring Person
no such  amendment  may  adversely  affect the  interests  of the holders of the
Rights.

Until a Right is exercised,  the holder thereof, as such, will have no rights as
a stockholder of the Company,  including,  without limitation, the right to vote
or to receive dividends.

The Rights have certain anti-takeover effects. The Rights will cause substantial
dilution to a person or group that  attempts to acquire the Company on terms not
approved  by the  Company's  Board of  Directors,  except  pursuant  to an offer
conditioned on a substantial number of Rights being acquired.  The Rights should
not  interfere  with any merger or other  business  combination  approved by the
Board of  Directors  since the  Rights  may be  redeemed  by the  company at the
Redemption  Price  prior  to the  time  that a  person  or  group  has  acquired
beneficial ownership of 15% or more of the Common Shares.

and Savings Bank, as Rights  Agent,  specifying  the terms of the Rights and the
form of press  release  announcing  the  declaration  of the rights are attached
hereto as exhibits  and are  incorporated  herein by  reference.  The  foregoing
description  of the Rights is  qualified  in its  entirety by  reference  to the
Rights Agreement in the exhibit attached hereto.
