                             CLASS ACTION COMPLAINT
                             ----------------------

     Plaintiff, by and through his attorneys, alleges upon information and
belief except as to himself and his own actions, which he alleges upon
knowledge, as follows:

                                     PARTIES
                                     -------

     1.  Plaintiff is the owner of Barrett Resources, Corp. ("Barrett" or the
"Company") common stock, and has owned such stock at all times relevant herein.

     2.  Barrett is a Delaware corporation with its principal place of business
located at 1515 Arapahoe Street Suite 1000, Denver, Colorado 80202. Barrett
explores for and produces oil and gas and owns and operates gas gathering
systems.


                                     - 1 -


     3.  Defendant William J. Barrett ("Barrett") is the chairman of Barrett's
Board of Directors.

     4.  Defendant Peter A. Dea ("Dea") is Vice Chairman of the Board of
Directors of Barrett and Chief Executive Officer.

     5.  Defendant Ralph A. Reed ("Reed") is President, Chief Operating Officer
and a Director of Barrett.

     6.  Defendant Frank J. Keller ("Keller") is Vice President, Chief Financial
Officer and a Director of Barrett.

     7.  Defendants Robert C. Buford, Derrill Cody, James M. Fitzgibbons,
Philippe S.E. Schreiber, Hennie L.J.M. Gieskes and William W. Grant, III, are
all directors of Barrett.

     8.  The foregoing individual Directors of Barrett (collectively, the
"Individual Defendants") owe fiduciary duties to Barrett and its Shareholders.


                           CLASS ACTION ALLEGATIONS
                           ------------------------

     9.  Plaintiff brings this action for injunctive and other relief on his own
behalf and as a class action, pursuant to Rule 23 of the Rules of the Court of
Chancery and on behalf of all common stockholders of Barrett (except defendants
herein and any person, firm, trust, corporation or other entity related to or
affiliated with any of the defendants) or their successors in interest, who are
being deprived of the opportunity to maximize the value of their Barrett shares
by the wrongful acts of the Individual Defendants described herein ("Class").

     10.  This action is properly maintainable as a class action for the
following reasons:

                                     - 2 -


          (a)  The Class for whose benefit this action is brought is so numerous
     that joinder of all class members is impracticable. There are more than 35
     million common shares of Barrett outstanding, owned by over 3,300 of
     stockholders of record. Members of the class are disbursed throughout the
     United States.

          (b)  There are questions of law and fact which are common to members
     of the Class and which predominate over all questions affecting only
     individual members, including whether the defendants have breached the
     fiduciary duties owed by them to plaintiff and members of the Class by
     reason of their efforts to entrench themselves in office and prevent
     Barrett public stockholders from maximizing the value of their holdings.

          (c)  The claims of plaintiff are typical of the claims of the other
     members of the Class and plaintiff has no interests that are adverse or
     antagonistic to the interests of the Class.

          (d)  Plaintiff is committed to the vigorous prosecution of this action
     and has retained competent counsel experienced in litigation in this
     nature. Accordingly, plaintiff is an adequate representative of the Class
     and will fairly and adequately protect the interests of the Class.

          (e)  The prosecution of separate actions by individual members of the
     Class would create a risk of inconsistent or varying adjudications with
     respect to individual members of the Class which would establish
     incompatible standards of conduct for the party opposing the Class.

          (f)  Defendants have acted and are about to act on grounds generally
     applicable to the Class, thereby making appropriate final injunctive or
     other equitable relief with respect to the Class as a whole.

                                     - 3 -


                              FACTUAL BACKGROUND
                              ------------------

     11.  On March 7, 2001, Royal Dutch/Shell Group ("Shell"), Europe's largest
oil company, publicly announced an offer to buy Barrett for $2.2 billion in cash
and assumed debt. Shell proposed paying $55.00 per share for Barrett or a total
of $1.8 billion in cash as well as assuming approximately $400 million of
Barrett's debt. This offer represents a 24% premium to the price of Barrett's
stock on February 28, 2001, the day Shell first approached the Company.
Following the offer, the Barrett Board stated that it would consider the
proposal at regularly scheduled meetings on March 7, 2001 and March 8, 2001 and
would respond to the offer no later than Friday, March 9, 2001.

     12.  On March 7, 2001, Shell Oil Company filed an action (the "Shell
Action") in Delaware Chancery Court challenging various by-law provisions of
Barrett. Apparently, by virtue of the Shell Action, Barrett and its Directors do
not intend to consider the Shell offer in accordance with their fiduciary duties
as described below.

     13.  At all times herein, the Individual Defendants were and are obligated
to adequately consider, in a timely fashion and on an informed basis, any
reasonable proposal from any party, not to place their own self-interests and
personal considerations ahead of the interests of the stockholders and to make
corporate decisions in good faith. The actions of the Individual Defendants were
fundamentally motivated to further their own self-interests and objectives, and
correspondingly preserve and protect their emoluments and positions in the
Company, all in violation of their fiduciary duties and to the detriment of the
shareholders of the Company.

                                     - 4 -


     14.  The Individual Defendants' fiduciary obligations require them to:

          (a)  undertake an appropriate evaluation of any bona fide offers, and
     take appropriate steps to solicit all potential bids for the Company or its
     assets or consider strategic alternatives;

          (b)  act independently, including appointing a disinterested committee
     so that the interests of Barrett's public stockholders would be protected;
     and

          (c)  adequately ensure that no conflicts of interest exist between
     defendants' own interests and their fiduciary obligations to the public
     stockholders of Barrett.

     15.  The Shell proposal represents an opportunity to effect a change of
control of Barrett, its business and affairs. In a change of control
transaction, the Individual Defendants necessarily and inherently suffer from a
conflict of interest between their own personal desires to retain their offices
in Barrett, with the emoluments and prestige which accompany those offices, and
their fiduciary obligation to maximize shareholder value in a change of control
transaction. Because of such conflicts of interest, it is unlikely that
defendants will be able to represent the interests of Barrett's public
stockholders with the impartiality that their fiduciary duties require, nor will
they be able to ensure that their conflicts of interest will be resolved in the
best interests of Barrett's public stockholders.

     16.  By virtue of the acts and conduct alleged herein, the Individual
Defendants, who direct the actions of the Company, are carrying out a
preconceived plan and scheme to entrench themselves in office and to protect and
advance their own parochial interests at the expense of Barrett. Defendants'
conduct wrongfully infringes on the Company's stockholders' ability to influence
corporate policy through the proxy mechanism.

                                     - 5 -


     17.  As a result of the foregoing, the Individual Defendants have breached
their fiduciary duties owed to Barrett's public stockholders.

     18.  Unless enjoined by this Court, defendants will continue to breach
their fiduciary duties owed to plaintiff and the other members of the Class and
entrench themselves in their corporate offices, all to the irreparable harm of
the Class.

     19.  Plaintiff and the other members of the Class have no adequate remedy
at law.

     WHEREFORE, plaintiff demands judgment as follows:

          (a)  declaring this to be a proper class action;

          (b)  ordering the Individual Defendants to carry out their fiduciary
     duties to plaintiff and the other members of the Class by announcing their
     intention to: (i) undertake an appropriate evaluation of alternatives
     designed to maximize value for Barrett's public stockholders; and (ii)
     adequately ensure that no conflicts of interests exist between defendants'
     own interests and their fiduciary obligations to public stockholders or, if
     such conflicts exist, ensure that all the conflicts would be resolved in
     the best interests of Barrett's public stockholders;

          (c)  ordering defendants, jointly and severally, to account to
     plaintiff and the other members of the Class for all damages suffered and
     to be suffered by them as a result of the acts and transactions alleged
     herein;

          (d)  awarding plaintiff the costs and disbursements of this action,
     including a reasonable allowance for plaintiffs attorney's fees and
     experts' fees; and

                                     - 6 -


          (e)  granting such other and further relief as this Court may deem to
     be just and proper.
