                 NATIONAL PATENT DEVELOPMENT CORPORATION
                         ADOPTS STOCKHOLDER RIGHTS PLAN


FOR IMMEDIATE RELEASE


      New  York,  New  York,  June  24,   1997..................National  Patent
Development  Corporation  (ASE:NPD)  announced today that its Board of Directors
has declared a dividend on its shares of Common Stock and Class B Capital  Stock
(collectively,  the "Common  Shares") of preferred share purchase rights as part
of a Stockholder Rights Plan.

      The Plan is  designed  to  insure  that all  stockholders  of the  Company
receive fair value for their Common Shares in the event of any proposed takeover
of the Company and to guard  against the use of partial  tender  offers or other
coercive  tactics to gain control of the Company without  offering fair value to
the Company's stockholders. At the present time the Company knows of no proposed
or  threatened  takeover,  tender  offer or other  effort to gain control of the
Company.

      Jerome I.  Feldman,  Chief  Executive  Officer of the Company,  said,  "We
believe  that this Plan  protects  stockholder  interests  in the event that the
Company is confronted with coercive or unfair takeover tactics, including offers
that do not treat all stockholders interests fairly or do not maximize the value
of the Company,  including  the  long-term  gains which the  stockholders  could
reasonably  expect  to  receive  if the  Company  remains  independent.  This is
especially  true,  because at the present  time,  management  believes  that the
Company is undervalued."

       Mr.  Feldman  stressed  that  "the  Plan is not  intended,  nor  will it
operate,  to prevent an  acquisition  of the Company on terms that are favorable
and fair to all stockholders. The Plan is designed to deal with the very serious
problem of  unilateral  actions  by hostile  acquirors  that are  calculated  to
deprive the Board and  stockholders of their ability to determine the destiny of
the Company.  Acquisition  offers that reflect the Company's fair value and that
are made to all stockholders would not be affected by the Plan."




      Under  the  terms  of the  Plan,  preferred  share  purchase  rights  (the
"Rights")  will be  distributed  as a dividend at the rate of one Right for each
Common Share held as of the close of business on July 3, 1997. Stockholders will
not actually  receive  certificates  for the Rights at this time, but the Rights
will become  part of each  Common  Share.  The number of Rights  outstanding  is
subject to adjustment under certain  circumstances and all rights expire on July
3, 2007.

      Each Right will  entitle the holder to buy 1/1000 of a share of a Series A
Junior Participating Preferred Shares of the Company (the "Preferred Shares") at
an exercise  price of $33.00.  Each  Preferred  Share fraction is designed to be
equivalent in voting and dividend rights to one Common Share. The Rights will be
exercisable and will trade separately from the Common Shares only if a person or
group (other than an Exempted  Person) acquires  beneficial  ownership of 20% or
more of the Company's Common Shares or commences a tender or exchange offer that
would result in such a person or group owning 20% or more of the Common  Shares.
Only  when  one  or  more  of  these  events  occur  will  stockholders  receive
certificates for the Rights.

      If any person actually acquires 20% or more of Common Shares -- other than
through a tender or exchange  offer for all Common  Shares that  provides a fair
price and other terms for such shares -- or if a 20%-or-more stockholder engages
in certain "self-dealing"  transactions or engages in a merger or other business
combination  in  which  the  Company  survives  and  its  Common  Shares  remain
outstanding,  the other  stockholders will be able to exercise the Right and buy
Common Shares (of the same class of Common Shares to which the Rights  attached)
of the  Company  having  twice the value of the  exercise  price of the  Rights.
Additionally,  if the  Company is involved in certain  other  mergers  where its
shares are exchanged or certain  major sales of its assets  occur,  stockholders
will be able to purchase the other  party's  common shares in an amount equal to
twice the value of the exercise price of the Rights.  Upon the occurrence of any
of these events, the Rights will no longer be exercisable into Preferred Shares.

      The Company will be entitled to redeem the Rights at $.01 per Right at any
time  until  the tenth  day  following  public  announcement  that a person  has
acquired a 20% ownership  position in Common Shares of the Company.  The Company
in its discretion may extend the period during which it can redeem the Rights.

current  view with respect to future  events and  financial  performance.  These
forward-looking  statements are subject to certain risks and uncertainties  that
could   cause   actual   results  to  differ   materially   from  those  in  the
forward-looking  statements,  all of which are  difficult to predict and many of
which are beyond the  control of the  Company,  including,  but not  limited to,
those risks and  uncertainties  detailed in the Company's  periodic  reports and
registration statements filed with the Securities and Exchange Commission.
