CERTIFICATE OF CORRECTION
                                   OF THE
              AMENDED AND RESTATED CERTIFICATE OF INCORPORATION
                                     OF
                               UNIT CORPORATION


     Unit Corporation, a corporation organized and existing under and by virtue
of the General Corporation Law of the State of Delaware (the "Corporation"),
DOES HEREBY CERTIFY:

1.   The Amended and Restated Certificate of Incorporation of the Corporation
was filed with the Secretary of State of the State of Delaware on May 16, 2000
and said Amended and Restated Certificate of Incorporation requires correction
as permitted by subsection (f) of Section 103 of the General Corporation Law of
the State of Delaware.

2.   The inaccuracy or defect of said Amended and Restated Certificate of
Incorporation to be corrected is that the terms of the Series A Participating
Cumulative Preferred Stock of the Corporation, as set forth in the Certificate
of Designation of the Corporation as filed with the Secretary of State of the
State of Delaware on September 16, 1999, were inadvertently omitted from said
Amended and Restated Certificate of Incorporation and should be included
therein.

3.   Said Amended and Restated Certificate of Incorporation is corrected by
inserting the following at the end of Article Four and by attaching thereto
Annex 1 attached hereto:

   Pursuant to authority conferred by this Article Four upon the Board of
   Directors of the Corporation, the Board of Directors created a series of
   250,000 shares of Preferred Stock designated as Series A Participating
   Cumulative Preferred Stock by filing a Certificate of Designation of the
   Corporation with the Secretary of State of the State of Delaware on
   September 16, 1999, and the voting powers, designations, preferences and
   relative, participating and other special rights, and the qualifications,
   limitations and restrictions thereof, of the Series A Participating
   Cumulative Preferred Stock of the Corporation are as set forth in Annex 1
   hereto and are incorporated herein by reference.

   IN WITNESS WHEREOF, the Corporation has caused this Certificate to be
executed by its duly authorized officer this 19th day of April, 2001.

                             UNIT CORPORATION


                             By:___________________________
                             Name: John G. Nikkel
                             Title: President











                                 ANNEX 1


          SECTION 1.  Designation and Number of Shares.  The shares of such
series shall be designated as "Series A Participating Cumulative Preferred
Stock" (the "Series A Preferred Stock"), par value $1.00 per share.  The number
of shares initially constituting the Series A Preferred Stock shall be 250,000;
provided, however, that, if more than a total of 250,000 shares of Series A
Preferred Stock shall be issuable upon the exercise of Rights (the "Rights")
issued pursuant to the Rights Agreement dated as of May 19, 1995, between the
Corporation and Chemical Bank, a New York banking corporation, as Rights Agent
(the "Rights Agreement"), the Board of Directors of the Corporation, pursuant to
Section 151(g) of the General Corporation Law of the State of Delaware, shall
direct by resolution or resolutions that a certificate be properly executed,
acknowledged, filed and recorded, in accordance with the provisions of Section
103 thereof, providing for the total number of shares of Series A Preferred
Stock authorized to be issued to be increased (to the extent that the
Certificate of Incorporation then permits) to the largest number of whole shares
(rounded up to the nearest whole number) issuable upon exercise of such Rights.

          SECTION 2.  Dividends or Distributions.  (a) Subject to the prior and
superior rights of the holders of shares of any other series of Preferred Stock
or other class of capital stock of the Corporation ranking prior and superior to
the shares of Series A Preferred Stock with respect to dividends, the holders of
shares of the Series A Preferred Stock shall be entitled to receive, when, as
and if declared by the Board of Directors, out of the assets of the Corporation
legally available therefor,  (1) quarterly dividends payable in cash on the last
day of each fiscal quarter in each year, or such other dates as the Board of
Directors of the Corporation shall approve (each such date being referred to
herein as a "Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of a share or a
fraction of a share of Series A Preferred Stock, in the amount of $1.00 per
whole share (rounded to the nearest cent) less the amount of all cash dividends
declared on the Series A Preferred Stock pursuant to the following clause (2)
since the immediately preceding Quarterly Dividend Payment Date or, with respect
to the first Quarterly Dividend Payment Date, since the first issuance of any
share or fraction of a share of Series A Preferred Stock (the total of which
shall not, in any event, be less than zero) and (2) dividends payable in cash on
the payment date for each cash dividend declared on the Common Stock in an
amount per whole share (rounded to the nearest cent) equal to the Formula Number
(as hereinafter defined) then in effect times the cash dividends then to be paid
on each share of Common Stock.  In addition, if the Corporation shall pay any
dividend or make any distribution on the Common Stock payable in assets,
securities or other forms of noncash consideration (other than dividends or
distributions solely in shares of Common Stock), then, in each such case, the
Corporation shall simultaneously pay or make on each outstanding whole share of
Series A Preferred Stock a dividend or distribution in like kind equal to the
Formula Number then in effect times such dividend or distribution on each share
of the Common Stock.  As used herein, the "Formula Number" shall be 100;
provided, however, that, if at any time after May 19, 1995 the Corporation shall
(i) declare or pay any dividend on the Common Stock payable in shares of Common
Stock or make any distribution on the Common Stock in shares of Common Stock,
(ii) subdivide (by a stock split or otherwise) the outstanding shares of Common
Stock into a larger number of shares of Common Stock or (iii) combine (by a
reverse stock split or otherwise) the outstanding shares of Common Stock into a
smaller number of shares of Common Stock, then in each such event the Formula
Number shall be adjusted to a number determined by multiplying the Formula
Number in effect immediately prior to such event by a fraction, the numerator of
which is the number of shares of Common Stock that are outstanding immediately
after such event and the denominator of which is the number of shares of Common
Stock that are outstanding immediately prior to such event (and rounding the
result to the nearest whole number); and provided further, that, if at any time
after May 19, 1995, the Corporation shall issue any shares of its capital stock
in a merger, reclassification, or change of the outstanding shares of Common
Stock, then in each such event the Formula Number shall be appropriately
adjusted to reflect such merger, reclassification or change so that each share
of Preferred Stock continues to be the economic equivalent of a Formula Number
of shares of Common Stock prior to such merger, reclassification or change.

          (b) The Corporation shall declare a dividend or distribution on the
Series A Preferred Stock as provided in Section 2(a) immediately prior to or at
the same time it declares a dividend or

                                     A-1


distribution on the Common Stock (other than a dividend or distribution solely
in shares of Common Stock); provided, however, that, in the event no dividend or
distribution (other than a dividend or distribution in shares of Common Stock)
shall have been declared on the Common Stock during the period between any
Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend
Payment Date, a dividend of $1.00 per share on the Series A Preferred Stock
shall nevertheless be payable on such subsequent Quarterly Dividend Payment
Date.  The Board of Directors may fix a record date for the determination of
holders of shares of Series A Preferred Stock entitled to receive a dividend or
distribution declared thereon, which record date shall be the same as the record
date for any corresponding dividend or distribution on the Common Stock.

          (c) Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Preferred Stock from and after the Quarterly Dividend Payment
Date next preceding the date of original issue of such shares of Series A
Preferred Stock; provided, however, that dividends on such shares which are
originally issued after the record date for the determination of holders of
shares of Series A Preferred Stock entitled to receive a quarterly dividend and
on or prior to the next succeeding Quarterly Dividend Payment Date shall begin
to accrue and be cumulative from and after such Quarterly Dividend Payment Date.
Notwithstanding the foregoing, dividends on shares of Series A Preferred Stock
which are originally issued prior to the record date for the determination of
holders of shares of Series A Preferred Stock entitled to receive a quarterly
dividend on the first Quarterly Dividend Payment Date shall be calculated as if
cumulative from and after the last day of the fiscal quarter next preceding the
date of original issuance of such shares. Accrued but unpaid dividends shall not
bear interest. Dividends paid on the shares of Series A Preferred Stock in an
amount less than the total amount of such dividends at the time accrued and
payable on such shares shall be allocated pro rata on a share-by-share basis
among all such shares at the time outstanding.

          (d) So long as any shares of the Series A Preferred Stock are
outstanding, no dividends or other distributions shall be declared, paid or
distributed, or set aside for payment or distribution, on the Common Stock
unless, in each case, the dividend required by this Section 2 to be declared on
the Series A Preferred Stock shall have been declared.

          (e) The holders of the shares of Series A Preferred Stock shall not be
entitled to receive any dividends or other distributions except as provided
herein.

          SECTION 3.  Voting Rights.  The holders of shares of Series A
Preferred Stock shall have the following voting riqhts:

          (a) Each holder of Series A Preferred Stock shall be entitled to a
number of votes equal to the Formula Number then in effect, for each share of
Series A Preferred Stock held of record on each matter on which holders of the
Common Stock or stockholders generally are entitled to vote, multiplied by the
maximum number of votes per share which any holder of the Common Stock or
stockholders generally then have with respect to such matter (assuming any
holding period or other requirement to vote a greater number of shares is
satisfied).

          (b) Except as otherwise provided herein or by applicable law, the
holders of shares of Series A Preferred Stock and the holders of shares of
Common Stock shall vote together as one class for the election of directors of
the Corporation and on all other matters submitted to a vote of stockholders of
the Corporation.

          (c) Except as provided herein, in Section 11 or by applicable law,
holders of Series A Preferred Stock shall have no special voting rights and
their consent shall not be required (except to the extent they are entitled to
vote with holders of Common Stock as set forth herein) for authorizing or taking
any corporate action.

          SECTION 4.  Certain Restrictions.  (a) Whenever quarterly dividends or
other dividends or distributions payable on the Series A Preferred Stock as
provided in Section 2 are in arrears, thereafter

                                     A-2


and until all accrued and unpaid dividends and distributions, whether or not
declared, on shares of Series A Preferred Stock outstanding shall have been paid
in full, the Corporation shall not

          (i) declare or pay dividends on, make any other distributions on, or
     redeem or purchase or otherwise acquire for consideration any shares of
     stock ranking junior (either as to dividends or upon liquidation,
     dissolution or winding up) to the Series A Preferred Stock;

          (ii) declare or pay dividends on or make any other distributions on
     any shares of stock ranking on a parity (either as to dividends or upon
     liquidation, dissolution or winding up) with the Series A Preferred Stock,
     except dividends paid ratably on the Series A Preferred Stock and all such
     parity stock on which dividends are payable or in arrears in proportion to
     the total amounts to which the holders of all such shares are then
     entitled;

          (iii) redeem or purchase or otherwise acquire for consideration shares
     of any stock ranking on a parity (either as to dividends or upon
     liquidation, dissolution or winding up) with the Series A Preferred Stock;
     provided that the Corporation may at any time redeem, purchase or otherwise
     acquire shares of any such parity stock in exchange for shares of any stock
     of the Corporation ranking junior (either as to dividends or upon
     dissolution, liquidation or winding up) to the Series A Preferred Stock; or

          (iv) purchase or otherwise acquire for consideration any shares of
     Series A Preferred Stock, or any shares of stock ranking on a parity with
     the Series A Preferred Stock, except in accordance with a purchase offer
     made in writing or by publication (as determined by the Board of Directors)
     to all holders of such shares upon such terms as the Board of Directors,
     after consideration of the respective annual dividend rates and other
     relative rights and preferences of the respective series and classes, shall
     determine in good faith will result in fair and equitable treatment among
     the respective series or classes.

          (b) The Corporation shall not permit any subsidiary of the Corporation
to purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (a) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

          SECTION 5.  Liquidation Rights.  Upon the liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, no distribution
shall be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless prior thereto, the holders of shares of Series A
Preferred Stock shall have received an amount equal to the accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment, plus an amount equal to the greater of (x) $1.00 per whole share
or (y) an aggregate amount per share equal to the Formula Number then in effect
times the aggregate amount to be distributed per share to holders of Common
Stock or (2) to the holders of stock ranking on a parity (either as to dividends
or upon liquidation, dissolution or winding up) with the Series A Preferred
Stock, except distributions made ratably on the Series A Preferred Stock and all
other such parity stock in proportion to the total amounts to which the holders
of all such shares are entitled upon such liquidation, dissolution or winding
up.

          SECTION 6.  Consolidation, Merger, etc.  In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash or any other property, then in any such case the then
outstanding shares of Series A Preferred Stock shall at the same time be
similarly exchanged or changed into an amount per share equal to the Formula
Number then in effect times the aggregate amount of stock, securities, cash or
any other property (payable in kind), as the case may be, into which or for
which each share of Common Stock is exchanged or changed.  In the event both
this Section 6 and Section 2 appear to apply to a transaction, this Section 6
will control.

                                    A-3


          SECTION 7.  No Redemption; No Sinking Fund.  (a) The shares of Series
A Preferred Stock shall not be subject to redemption by the Corporation or at
the option of any holder of Series A Preferred Stock; provided, however, that
the Corporation may purchase or otherwise acquire outstanding shares of Series A
Preferred Stock in the open market or by offer to any holder or holders of
shares of Series A Preferred Stock.

          (b) The shares of Series A Preferred Stock shall not be subject to or
entitled to the operation of a retirement or sinking fund.

          SECTION 8.  Ranking. The Series A Preferred Stock shall rank junior to
all other series of Preferred Stock of the Corporation, unless the Board of
Directors shall specifically determine otherwise in fixing the powers,
preferences and relative, participating, optional and other special rights of
the shares of such series and the qualifications, limitations and restrictions
thereof.

          SECTION 9.  Fractional Shares.  The Series A Preferred Stock shall be
issuable upon exercise of the Rights issued pursuant to the Rights Agreement in
whole shares or in any fraction of a share that is one one-hundredth (1/100th)
of a share or any integral multiple of such fraction which shall entitle the
holder, in proportion to such holder's fractional shares, to receive dividends,
exercise voting rights, participate in distributions and to have the benefit of
all other rights of holders of Series A Preferred Stock.  In lieu of fractional
shares, the Corporation, prior to the first issuance of a share or a fraction of
a share of Series A Preferred Stock, may elect (1) to make a cash payment as
provided in the Rights Agreement for fractions of a share other than one one-
hundredth (1/100th) of a share or any integral multiple thereof or (2) to issue
depository receipts evidencing such authorized fraction of a share of Series A
Preferred Stock pursuant to an appropriate agreement between the Corporation and
a depository selected by the Corporation; provided that such agreement shall
provide that the holders of such depository receipts shall have all the rights,
privileges and preferences to which they are entitled as holders of the Series A
Preferred Stock.

          SECTION 10.  Reacquired Shares.  Any shares of Series A Preferred
Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their cancellation become authorized but unissued
shares of Preferred Stock, without designation as to series until such shares
are once more designated as part of a particular series by the Board of
Directors pursuant to the provisions of Section 2 of Article IV of the
Certificate of Incorporation.

          SECTION 11.  Amendment.  None of the powers, preferences and relative,
participating, optional and other special rights of the Series A Preferred Stock
as provided herein or in the Certificate of Incorporation shall be amended in
any manner which would alter or change the powers, preferences, rights or
privileges of the holders of Series A Preferred Stock so as to affect them
adversely without the affirmative vote of the holders of at least 66-2/3% of the
outstanding shares of Series A Preferred Stock, voting as a separate class;
provided, however, that no such amendment approved by the holders of at least
66-2/3% of the outstanding shares of Series A Preferred Stock shall be deemed to
apply to the powers, preferences, rights or privileges of any holder of shares
of Series A Preferred Stock originally issued upon exercise of the Rights after
the time of such approval without the approval of such holder.
