Item 1.   Description of Securities to be Registered.

          On May 26, 1998, the Board of Directors of Elcor Corporation (the
"Company") declared a dividend distribution of one right (a "Right") for each
outstanding share of common stock, par value $1.00 per share, of the Company
(the "Common Stock") to shareholders of record at the close of business on July
8, 1998 (the "Record Date"). Each Right entitles the registered holder to
purchase from the Company one one-hundredth of a share of a series of cumulative
preferred stock of the Company designated Series A Participating Preferred Stock
(the "Preferred Stock"), at a price of $165 (the "Purchase Price"), subject to
adjustment. The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and ChaseMellon
Shareholder Services, L.L.C. as Rights Agent (the "Rights Agent").

          The Rights replace the preferred stock purchase rights (the "Old
Rights") issued pursuant to a Rights Agreement dated as of June 28, 1988, as
amended and restated as of January 29, 1991, between the Company and NCNB Texas
National Bank (as successor to First RepublicBank Dallas, N.A., as Rights Agent
(the "Old Rights Agreement"). The Old Rights Agreement and the Old Rights are
scheduled to expire at the close of business on July 8, 1998 pursuant to the
terms thereof.

          Initially, the Rights will be attached to all Common Stock
certificates representing shares then outstanding, and no separate Rights
Certificates will be distributed. The Rights will separate from the Common
Stock and a Distribution Date will occur upon the earlier of (i) 10 days
following a public announcement that a person or group of affiliated or
associated persons (an "Acquiring Person") has acquired, or obtained the right
to acquire, beneficial ownership of 15% or more of the outstanding shares of
Common Stock (the "Stock Acquisition Date"), or (ii) 10 business days following
the commencement of a tender offer or exchange offer that would result in a
person or group beneficially owning 15% or more of such outstanding shares of
Common Stock or such later date as may be determined by action of the Board of
Directors prior to such time as any Person becomes an Acquiring Person. Until
the Distribution Date, (i) the Rights will be evidenced by the Common Stock
certificates and will be transferred with and only with such Common Stock
certificates, (ii) new Common Stock certificates issued after the Record Date
will contain a notation incorporating the Rights Agreement by reference and
(iii) the surrender for transfer of any certificates for Common Stock
outstanding will also constitute the transfer of the Rights associated with the
Common Stock represented by such certificate.

          Certain institutional investors will not be deemed to be the
beneficial owner of shares of Common Stock held by them for the benefit of
third parties or in customer accounts so long as (a) the Board of Directors of
the Company shall not have determined that such shares were acquired by or are
held by such institutional investor with the purpose or effect of changing or
influencing control of the Company or evading certain securities law reporting
requirements and (b) such shares, together with all other shares of Common
Stock beneficially owned by such institutional investor and its affiliates and
associates, shall not exceed 20% of the outstanding shares of Common Stock.
   3


          The Rights are not exercisable until the Distribution Date and will
expire at the close of business on July 8, 2008, unless earlier redeemed by the
Company as described below.

          As soon as practicable after the Distribution Date, Rights
Certificates will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and, thereafter, the separate Rights
Certificates alone will represent the Rights. Except as otherwise determined by
the Board of Directors, only shares of Common Stock issued prior to the
Distribution Date will be issued with Rights.

          In the event that a Person becomes the beneficial owner of 15% or more
of the outstanding shares of Common Stock, each holder of a Right will
thereafter have the right to receive, upon exercise, Common Stock (or, in
certain circumstances, cash, property or other securities of the Company)
having a value equal to two times the exercise price of the Right.
Notwithstanding the foregoing, following the occurrence of an event set forth
in this paragraph, all Rights that are, or (under certain circumstances
specified in the Rights Agreement) were, beneficially owned by any Acquiring
Person will be null and void.

          For example, at an exercise price of $165 per Right, each Right not
owned by an Acquiring Person (or by certain related parties) following an event
set forth in the preceding paragraph would entitle its holder to purchase $330
of then-current market value of Common Stock (or other consideration, as noted
above) for $165. Assuming that the Common Stock had a per share value of $33 at
such time, the holder of each valid Right would be entitled to purchase 10
shares of Common Stock for $165.

          In the event that, at any time following the Stock Acquisition Date,
(i) the Company is acquired in a merger or other business combination
transaction in which the Company is not the surviving corporation, (ii) the
Company is the surviving corporation in a consolidation or merger in which all
or part of the outstanding shares of Common Stock of the Company are changed
into or exchanged for other securities or property, or (iii) 50% or more of the
Company's assets or earning power is sold or transferred (in each case other
than certain consolidations with, mergers with and into or sales of assets or
earning power by or to subsidiaries of the Company as specified in the Rights
Agreement), each holder of a Right (except Rights which previously have been
voided as set forth above) shall thereafter have the right to receive, upon
exercise, Common Stock of the acquiring company having a value equal to two
times the exercise price of the Right. The events described in this paragraph
and in the second preceding paragraph are referred to as the "Triggering
Events."
   4

          The Purchase Price payable, the number and kind of shares covered by
each Right and the number of Rights outstanding are subject to adjustment from
time to time to prevent dilution (i) in the event of a stock dividend on, or a
subdivision, combination or reclassification of, the Preferred Stock, (ii) if
holders of the Preferred Stock are granted certain rights or warrants to
subscribe for Preferred Stock or securities convertible into Preferred Stock at
less than the current market price of the Preferred Stock, or (iii) upon the
distribution to holders of the Preferred Stock of evidence of indebtedness,
cash (excluding regular quarterly cash dividends), assets (other than dividends
payable in Preferred Stock) or of subscription rights or warrants (other than
those referred to (ii) immediately above).

          With certain exceptions, no adjustments in the Purchase Price will be
required until cumulative adjustments amount to at least 1% of the Purchase
Price. No fractional shares of Preferred Stock will be issued (other than
fractions which are integral multiples of one one-hundredth of a share of
Preferred Stock) and, in lieu thereof, an adjustment in cash will be made based
on the market price of the Preferred Stock on the last trading date prior to
the date of exercise.

          At any time after any Person becomes an Acquiring Person and prior to
the acquisition by any Person of 50% or more of the outstanding Common Stock of
the Company, the Board of Directors of the Company may exchange the Rights
(other than Rights owned by any such Person, which will have become void), in
whole or in part, at an exchange ratio of one share of Common Stock per Right,
subject to adjustment.

          The Company may, at any time prior to such time as any Person becomes
an Acquiring Person, redeem the Rights in whole, but not in part, at a price of
$.01 per Right (payable in cash, Common Stock or other consideration deemed
appropriate by the Board of Directors). Immediately upon the action of the
Board of Directors ordering redemption of the rights, the Rights will terminate
and the only right of the holders of Rights will be to receive the $.01
redemption price.

          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. While the distribution of the Rights
will not be taxable to stockholders or to the Company, stockholders may,
depending upon the circumstances, recognize taxable income in the event that
the Rights become exercisable for Common Stock (or other consideration) of the
Company or for common stock of the acquiring company as set forth above or in
the event that the Rights are redeemed.

          The provisions of the Rights Agreement may be amended by the Board of
Directors at any time without the consent of the holders of the Rights;
provided, however, that from and after such time as any Person becomes an
Acquiring Person, the provisions of the Rights Agreement may not be amended in
any manner that would adversely affect the interests of the holders of the
Rights.

          A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an exhibit to a Current Report on Form 8-K dated
May 26, 1998.  A
   5
copy of the Rights Agreement will be available free of charge from the Company.
This summary description of the Rights does not purport to be complete and is
qualified in its entirety by reference to the Rights Agreement, which is
incorporated herein by reference.

          As of May 22, 1998, there were 13,286,625 shares of Common Stock
outstanding and 840,011 shares of Common Stock reserved for issuance under the
Company's stock plans. Each share of Common Stock outstanding on July 8, 1998
will receive one Right. As long as the Rights are attached to the Common Stock,
the Registrant will issue one right with each share of Common Stock it issues.
150,000 shares of Preferred Stock are reserved for issuance upon exercise of
the Rights.

          The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
without conditioning the offer on a substantial number of Rights being
acquired. In general, the Rights should not interfere with any merger or other
business combination approved by the Board of Directors of the Company since
the Board of Directors generally may, at its option, redeem at any time prior
to the time a Person becomes an Acquiring Person all, but not less than all,
the then outstanding Rights at the redemption price.

PRESS RELEASE
FOR IMMEDIATE RELEASE





                          ELCOR CORPORATION ADOPTS NEW
                            SHAREHOLDER RIGHTS PLAN

DALLAS, TX, May 26, 1998--Elcor Corporation announced today that its
Board of Directors adopted a new Shareholder Rights Plan which will take effect
when the current rights plan expires on July 8, 1998.

Under the new plan, which is similar to the expiring plan, rights will be
distributed as a dividend at the rate of one right for each share of common
stock of the Company held by the shareholders of record as of the close of
business on July 8, 1998. Each right will entitle shareholders to buy, upon
occurrence of certain events, one one-hundredth of a share of preferred stock
for $165.  Should any person or group acquire beneficial ownership of 15% or
more of the Company's common stock, other than certain bona fide institutional
investors to whom a 20% threshold applies, all rights not held by the 15%
stockholder become rights to purchase Elcor common stock at a 50% discount.

Under certain circumstances, the rights are redeemable at a price of $0.01 per
right. The rights will expire on July 8, 2008, unless redeemed earlier.

                                      ---
