ITEM 5.           OTHER EVENTS.

I.       Rights Plan

         On March 27, 1997,  the Board of  Directors  of CAIRN ENERGY USA,  INC.
(the  "Company")  declared a dividend of one preferred  share  purchase right (a
"Right") for each  outstanding  share of common stock, par value $.01 per share,
of the Company (the "Common  Stock").  The dividend is payable on April 11, 1997
(the  "Record  Date") to the  stockholders  of record on that  date.  Each Right
entitles the registered  holder to purchase from the Company one  one-thousandth
of a share of Series A Junior Participating  Preferred Stock, par value $.01 per
share,  of the  Company  (the  "Preferred  Stock")  at a  price  of $40  per one
one-thousandth of a share of Preferred Stock (the "Purchase Price"),  subject to
adjustment.  The  description  and terms of the Rights are set forth in a Rights
Agreement  dated as of April 1, 1997,  as the same may be  amended  from time to
time (the "Rights Agreement"), between the Company and STOCK TRANSFER COMPANY OF
AMERICA, INC., as Rights Agent (the "Rights Agent").


         Detachment  of Rights:  Exercise.  Until the earlier to occur of (i) 10
days  following a public  announcement  that a person or group of  affiliated or
associated persons (with certain exceptions, an "Acquiring Person") has acquired
beneficial ownership of 15% or more of the outstanding shares of Common Stock 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
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  shares of Common Stock (the earlier of
such dates being called the "Distribution  Date"), the Rights will be evidenced,
with  respect  to any of the Common  Stock  certificates  outstanding  as of the
Record  Date,  by such Common  Stock  certificate  together  with a copy of this
Summary of Rights.

         The Rights Agreement  provides that,  until the  Distribution  Date (or
earlier expiration of the Rights),  the Rights will be transferred with and only
with the Common Stock. Until the Distribution Date (or earlier expiration of the
Rights),  new  Common  Stock  certificates  issued  after the  Record  Date upon
transfer or new issuances of Common Stock will contain a notation  incorporating
the Rights  Agreement  by  reference.  Until the  Distribution  Date (or earlier
expiration of the Rights),  the surrender for transfer of any  certificates  for
shares of Common  Stock  outstanding  as of the Record  Date,  even without such
notation or a copy of this Summary of Rights,  will also constitute the transfer
of the Rights  associated  with the shares of Common Stock  represented  by such
certificates.  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  Stock as of the  close of  business  on the
Distribution Date and such separate Right  Certificates  alone will evidence the
Rights.




CORPDAL:63397.2 15467-00006
                                                         2





         The Rights are not exercisable until the Distribution  Date. The Rights
will expire on March 31, 2007 (the "Final  Expiration  Date"),  unless the Final
Expiration  Date is  advanced  or  extended  or unless the  Rights  are  earlier
redeemed or exchanged by the Company, in each case as described below.

         In the event  that any  person  or group of  affiliated  or  associated
persons becomes an Acquiring Person,  each holder of a Right,  other than Rights
beneficially  owned by the Acquiring  Person (which will thereupon become void),
will  thereafter  have the right to receive upon exercise of a Right that number
of shares of Common Stock having a market value of two times the exercise  price
of the Right.

         In the event  that,  after a person or group  has  become an  Acquiring
Person,  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,
proper provisions will be made so that each holder of a Right (other than Rights
beneficially  owned by an  Acquiring  Person  which will have become  void) will
thereafter have the right to receive upon the exercise of a Right that number of
shares of common  stock of the person  with whom the  Company has engaged in the
foregoing  transaction (or its parent) that at the time of such transaction have
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 earlier of one of the events described in the previous paragraph or
the  acquisition  by such  Acquiring  Person  of 50% or more of the  outstanding
shares of Common  Stock,  the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such Acquiring  Person which will have become
void),  in whole or in part, for shares of Common Stock or Preferred Stock (or a
series of the Company's  preferred stock having equivalent  rights,  preferences
and  privileges),  at an  exchange  ratio of one  share of  Common  Stock,  or a
fractional  share of Preferred  Stock (or other preferred  stock)  equivalent in
value thereto, per Right.

         Preferred  Shares.  Shares of Preferred Stock purchasable upon exercise
of the Rights  will not be  redeemable.  Each share of  Preferred  Stock will be
entitled,  when, as and if declared, to a dividend payment per share equal to an
aggregate  dividend  of 1000  times the  dividend  declared  per share of Common
Stock.  In the event of  liquidation,  dissolution or winding up of the Company,
the holders of the  Preferred  Stock will be entitled to a minimum  preferential
payment of $1.00 per share (plus any accrued but unpaid  dividends)  but will be
entitled to an  aggregate  payment of 1000 times the  payment  made per share of
Common  Stock.  Each  share of  Preferred  Stock  will have 1000  votes,  voting
together  with  the  Common  Stock.   Finally,  in  the  event  of  any  merger,
consolidation or other transaction in which  outstanding  shares of Common Stock
are  converted or exchanged,  each share of Preferred  Stock will be entitled to
receive 1000 times the amount  received per share of Common Stock.  These Rights
are protected by customary antidilution provisions.




CORPDAL:63397.2 15467-00006
                                                         3





         Because of the nature of the Preferred  Stock's  dividend,  liquidation
and voting rights,  the value of the one  one-thousandth  interest in a share of
Preferred Stock purchasable upon exercise of each Right should approximately the
value of one share of Common Stock.

         The offer and sale of the Preferred  Shares or Common  Shares  issuable
upon exercise of the Rights will be registered pursuant to the Securities Act of
1933, as amended;  such  registration will not become effective until the Rights
become exercisable.

         Antidilution and Other Adjustments.  The number of one  one-thousandths
of a Preferred Share or other  securities or property  issuable upon exercise of
the Rights, and the Purchase Price payable, are subject to customary adjustments
from time to time to prevent dilution.

         Redemption  of  Rights.  At any time  prior to the  earlier  of (i) the
Distribution  Date or (ii) the Final  Expiration Date, the Board of Directors of
the Company may redeem all but not less than all of the then outstanding  Rights
at a price of $0.01 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.  At
the  effective  time of such  redemption,  the right to exercise the Rights will
terminate  and the only right of the  holders of Rights  will be to receive  the
Redemption Price.

         No  Rights  as  Stockholder.  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.

         Amendment of Rights. For so long as the Rights are then redeemable, the
Company  may,  except with  respect to the  redemption  price,  amend the Rights
Agreement in any manner. After the Rights are no longer redeemable,  the Company
may, except with respect to the redemption price,  amend the Rights Agreement in
any  manner  that does not  adversely  affect  the  interests  of holders of the
Rights.

         This summary  description of the Rights does not purport to be complete
and is qualified in its  entirety by  reference  to the Rights  Agreement  filed
herewith as Exhibit 4.1, which is hereby incorporated by reference.
