ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS

     The Registrant and its wholly owned subsidiary, Unit Drilling Company ("
Unit Drilling"), have  completed the acquisition of Hickman Drilling Company, an
Oklahoma corporation ( "Hickman Drilling"). Under the terms of this acquisition,
all of the holders of the capital stock of Hickman Drilling ( the
"Shareholders") received, in the aggregate, 1,300,000 shares of UNIT common
stock, par value $0.20 per share ( the "UNIT Common Stock")  and promissory
notes to be issued in the aggregate principal  amount of  $5,000,000, subject to
adjustment as described below,  to be paid in five equal annual installments
commencing January 2, 1999 ( the "Cash Consideration"). The total consideration
paid by UNIT was determined through negotiations between the parties. The
promissory notes are expected to be paid out of available cash flow.

     The terms and conditions of the acquisition are set forth in an  Agreement
and Plan of Merger (the "Merger Agreement") executed and closed on Thursday,
November 20, 1997, by and among the Registrant, Hickman Drilling , the
Shareholders and Unit Drilling.  Pursuant to the Merger Agreement and a
Certificate of Merger filed November 21, 1997, Hickman Drilling was merged with
and into Unit Drilling.

     The aggregate principle amount of the promissory notes is subject to
adjustment in the event the working capital of Hickman Drilling, as of November
21, 1997, subject to certain adjustments is determined to be less than $2.3
million. In such event, the Cash Consideration will be reduced in an amount
equal to the difference between the actual adjusted working capital amount as of
such date and $2.3 million.

     Hickman Drilling's operations  were located primarily in the Texas and
Oklahoma panhandle areas and it employed  approximately 140  people,
substantially all of whom it is expected will continue their employment with
Unit Drilling. Hickman Drilling's principal operating assets consisted of its
fleet of 9 medium depth capacity land drilling rigs, related equipment and
vehicles. Unit Drilling intends to continue to use the acquired equipment in its
drilling operations.  Certain information concerning Hickman Drilling's rig
fleet is set forth in the table below:

UDC as soon as practicable following the satisfaction or waiver, if permissible,
of the conditions set forth in this Agreement, and with the Shareholders
receiving the Merger Consideration.  Following the Merger, UDC will continue as
the surviving corporation (the "Surviving Corporation") under the name "Unit
Drilling Company" and will continue its existence under the laws of the State of
Oklahoma, and the separate corporate existence of the Company will cease.

2.2  Effective Time of the Merger

The Merger shall not become effective until, and, subject to the terms and
conditions of this Agreement, shall become effective when the following actions
shall have in all respects been completed:

     (a)  this Agreement shall have been approved by the shareholders of UDC and
          the Company in accordance with the requirements of Oklahoma Law; and

     (b)  the Certificate of Merger shall have been filed, in accordance with
          the requirements of Oklahoma Law, in the office of the Secretary of
          State of the State of Oklahoma.

The date and time when the Merger shall become effective as aforesaid is herein
referred to as the "Effective Time of the Merger."

2.3  Organizational Documents; Directors and Officers

     (a)  The Organizational Documents of UDC, as in effect immediately prior to
the Effective Time of the Merger, shall be the Organizational Documents of the
Surviving Corporation from and after the Effective Time of the Merger until
amended in accordance with Oklahoma Law.









                                                                          10

<PAGE>
     (b)  The officers of UDC in office immediately prior to the Effective Time
of the Merger shall be the officers of the Surviving Corporation from and after
the Effective Time of the Merger, each to hold office in accordance with the
Organizational Documents of the Surviving Corporation.

     (c)  The directors of UDC in office immediately prior to the Effective Time

Organizational Documents of the Surviving Corporation.

2.4  Closing

The consummation of the transactions contemplated by Section 2.01 together with
the delivery of the various certificates, agreements, opinions and other
documents required or contemplated by this Agreement is called the "Closing".

The Closing will take place at the offices of UNIT at 1000 Kensington Tower I,
7130 South Lewis, Tulsa, Oklahoma, at 10:00 a.m. (local time) on the later of
(i) November 20, 1997 or (ii) the date that is two business days following the
termination of the applicable waiting period under the HSR Act, or at such other
time and place as the parties may agree. Subject to the provisions of Article
10, failure to consummate the purchase and sale provided for in this Agreement
on the date and time and at the place determined pursuant to this Section 2.4
will not result in the termination of this Agreement and will not relieve any
party of any obligation under this Agreement.

2.5  Conversion of the Shares in the Merger

     (a)  By virtue of the consummation of the Merger, the Shares shall be
converted into the right to receive the Merger Consideration in the manner and
at the time provided for in Sections 2.5(b) and 2.6.  The total maximum Merger
Consideration provided herein is to be 1,300,000 shares of UNIT Common Stock and
Promissory Notes (in the form of Attachment A to this Agreement) in the
aggregate original principal amount of $5,000,000 (the "Merger Consideration");
provided, however, that the aggregate original principal amount of the
Promissory Notes shall be reduced on a dollar for dollar basis by the amount
that the actual working capital of the Company as of the Effective Time of the
Merger, as determined in accordance with GAAP, is less than the amount of
the working capital reflected in the  Balance Sheet (the "Working Capital
Amount").  As promptly as practicable after the Effective Time of the Merger,
UNIT and its independent accounting firm, in cooperation with the  employees and
accounting representatives of the Company, shall review the books and records of
the Company for the period in question to develop a balance sheet for the
Company as of the Effective Time of the Merger (the "Closing Balance Sheet").
If the amount of the working capital reflected on the Closing Balance Sheet is
less than the Working Capital Amount, the aggregate original principal amount of
the Promissory Notes shall be reduced by the amount of such difference;
provided, however, that notwithstanding anything to the contrary in the
foregoing, for purposes of the adjustment in the amount of the Merger
Consideration under this Section 2.5 only, there shall be added to the working
capital reflected in the Closing Balance Sheet an amount equal to $248,116
(representing capital expenditures of the Company during the period from the




                                                                          11

<PAGE>
date of the Balance Sheet to September 30, 1997 which UNIT has determined are
acceptable additions) plus such additional amounts of capital expenditures
incurred by the Company subsequent to September 30, 1997 to which the parties
may agree (UNIT's agreement in this instance to be consistent with the
methodology used for capital expenditures before September 30, 1997).  In the
event there is a adjustment required pursuant to this Section 2.5, the original
principal amount of each of the Promissory Notes shall be proportionately
reduced to reflect such adjustment.  The Promissory Notes shall not be issued
until such determination has been made but the interest due on the outstanding
principal amount of the Promissory Notes as finally issued shall accrue from the
Effective Date of the Merger.

     (b)  At the Effective Time of the Merger, each of the outstanding shares of
the capital stock of the Company shall, by virtue of the Merger and without any
action on the part of the holder thereof, be converted into the right to receive
the following portions of the total Merger Consideration (as hereinafter
defined) upon surrender of the certificates evidencing such shares as set
forth below:

Notwithstanding anything to the contrary in the foregoing, fractional shares of
UNIT Common Stock shall not be issued and that any such fractional shares
otherwise issuable pursuant to this Section 2.5 shall be rounded to the nearest
whole number.  Unless otherwise agreed, each holder of shares of the Company's
capital stock shall be entitled to receive a single Promissory Note evidencing
the aggregate original principal amount to which such holder is entitled to
receive by reason of all of the shares of all classes of the Company's capital
stock which he or she holds at the Effective Time of the Merger.  From and after
the Effective Time of the Merger, each outstanding certificate which theretofore
evidenced ownership of and represented shares of any of the capital stock of the
Company shall be deemed for all purposes to evidence ownership of and to
represent the number of shares of UNIT Common Stock and the right to receive
payment of the aggregate principal amount evidenced by the Promissory Note into
which the shares of capital stock of the Company has been converted; provided,
however, that no dividends will be payable on shares of UNIT Common Stock
and no payments of principal or interest on the amounts evidenced by the
Promissory Notes will be payable until such time as the holder thereof has
surrendered the certificates formerly representing shares of the Company's
capital stock and has been issued new certificates evidencing such shares of
UNIT Common Stock and Promissory Notes into which such shares of the Company's
capital stock has been converted.

2.6  Delivery of Merger Consideration

Upon surrender of the certificates representing all of the outstanding shares of
the Company's capital stock to UNIT at or immediately following the Effective
Time of the Merger, the Company shall issue and deliver to the Shareholders the
UNIT Common Stock and the Promissory Notes to which they are thereby entitled;
provided, however, that no Promissory Notes shall be issued until such time
as the amount of the working capital of the Company as of the Effective Time of
the Merger has been determined and it has been determined whether any
adjustments in the amount payable under the terms of the Promissory Notes
pursuant to Section 2.5  is required.  After the Effective Time of the Merger,
there shall be no transfers on the stock transfer books of the Company of the
shares of the Company's capital stock which were outstanding immediately prior
to the Effective Time of the Merger.

2.7  Adjustments

If, between the date of this Agreement and the Effective Time of the Merger, any
of the outstanding shares of UNIT Common Stock shall have been changed into a
different number of shares or a different class by reason of any
reclassification, recapitalization, split-up, combination, exchange of shares or
readjustment, or a stock dividend thereon shall be declared with a record date
prior to the Effective Time of the Merger, the number of shares or class of UNIT
Common Stock to be issued and delivered in the Merger in exchange for each



                                                                          13

<PAGE>
outstanding share of the Company's capital stock as provided in this Agreement
shall be appropriately adjusted.  The $5,000,000 aggregate principal amount of
payments which the holders of shares of the Company's capital stock are entitled
to receive is subject to reduction as provided in Section 2.5, in which event,
the amount of cash per share receivable by the Shareholders shall be reduced
proportionately.  The amounts payable under the Promissory Notes are also
subject to possible offset as provided in this Agreement.


                             ARTICLE 3
                   REPRESENTATIONS AND WARRANTIES
                OF THE COMPANY AND THE SHAREHOLDERS

The Company and the Shareholders jointly and severally hereby represent and
warrant to UNIT and UDC as follows:

3.1  Organization and Good Standing

     (a)  Part 3.1 of the Disclosure Letter contains a complete and accurate
          list for the Company of the foreign jurisdictions in which it is
          authorized to do business.  The Company is a corporation duly
          organized, validly existing, and in good standing under the laws of
          the State of Oklahoma, with full corporate power and authority to
          conduct its business as it is now being conducted, to own or use the
          properties and assets that it purports to own or use, and to perform
          all its obligations under Applicable Contracts. Except as noted in the
          following sentence, the Company is duly qualified to do business as a
          foreign corporation and is in good standing under the laws of each
          state or other jurisdiction in which either the ownership or use of
          the properties owned or used by it, or the nature of the activities
          conducted by it, requires such qualification.  The Company is not
          qualified to do business in the State of Texas but it has paid all
          franchise taxes and other amounts that would be due and payable if
          the Company had been so qualified.  Neither the Company nor any of its
          shareholders (including UNIT after the Effective Time of the Merger)
          are or will be subject to any losses, costs, fines, penalties or other
          expenses or liabilities by reason of its failure to be qualified to do
          business in the State of Texas as a foreign corporation.

     (b)  Each Shareholder represents and warrants to  UNIT that (i) if the
          Shareholder holds Shares as the trustee of a trust, such trust is duly
          organized, validly existing and in good standing under the laws of its
          jurisdiction of organization; (ii) the execution, delivery and
          performance by the Shareholder of this Agreement will not conflict
          with, require a consent, waiver or approval under, or result in a
          breach or a default under, its governing trust instruments (if
          applicable), or any of the terms of any contract, commitment or other
          obligations (written or oral) to which the Shareholder either
          individually or as a trustee is bound; (iii) this Agreement has been
          duly executed and delivered by the Shareholder and constitutes a valid
          and binding obligation of the Shareholder, enforceable against the
          Shareholder in accordance with its terms, except as may be limited by
          bankruptcy, insolvency and other laws relating to and affecting




                                                                          14

<PAGE>
          creditors' rights generally and equitable remedies; (iv) if
          applicable, the execution, delivery and performance of this Agreement
          and the consummation by Shareholder of the transactions contemplated
          hereby have been approved by all necessary trust action on
          Shareholder's part; and (v) the Shareholder has the power, authority
          and legal capacity to execute and deliver this Agreement and perform
          his or her obligations under this Agreement;

     (c)  The Company has delivered to UNIT copies of the Organizational
          Documents of the Company, as currently in effect.

3.2  Authority; No Conflict

     (a)  This Agreement, assuming this Agreement constitutes a valid and
          binding obligation of UNIT and UDC, constitutes the legal, valid, and
          binding obligation of the Company, enforceable against the Company in
          accordance with its terms, except as such enforceability may be
          limited by bankruptcy or principles applicable to creditors'
          rights generally or governing the availability of equitable relief.
          Upon the execution and delivery by the Shareholders of the
          Shareholders' Releases and the execution and delivery by the required
          Shareholders of the Noncompetition Agreements (collectively, the
          "Shareholders' Closing Documents"), the Shareholders' Closing
          Documents will constitute the legal, valid, and binding obligations of
          the signatory Shareholders, enforceable against the signatory
          Shareholders in accordance with their respective terms. The Company
          has the absolute and unrestricted right, power, authority, and
          capacity to execute and deliver this Agreement and to perform its
          obligations under this Agreement.

     (b)  Neither the execution and delivery of this Agreement nor the
          consummation or performance of any of the Contemplated Transactions
          will, directly or indirectly (with or without notice or lapse of
          time):

                agreement of or relating to any Shareholder;

          (ii)  contravene, conflict with, or result in a violation of, or give
                any Governmental Body or other Person the right to challenge any
                of the Contemplated Transactions or to exercise any remedy or
                obtain any relief under, any Legal Requirement or any Order to
                which the Company or the Shareholders, or any of the assets
                owned or used by the Company, may be subject;

         (iii)  contravene, conflict with, or result in a violation of any of
                the terms or requirements of, or give any Governmental Body the
                right to revoke, withdraw, suspend, cancel, terminate, or
                modify, any Governmental Authorization that is held by the
                Company or that otherwise relates to the business of, or any of
                the assets owned or used by, the Company;



                                                                          15

<PAGE>
          (iv)  cause UNIT, or UDC or the Company to become subject to, or to
                become liable for the payment of, any Taxes other than any Taxes
                that may become payable as a result of actions taken by UNIT or
                UDC after the Closing;

           (v)  cause any of the assets owned by the Company to be reassessed or
                revalued by any taxing authority or other Governmental Body;

          (vi)  contravene, conflict with, or result in a violation or breach of
                any provision of, or give any Person the right to declare a
                default or exercise any remedy under, or to accelerate the
                maturity or performance of, or to cancel, terminate, or
                modify, any Applicable Contract; or

         (vii)  result in the imposition or creation of any Encumbrance upon or
                with respect to any of the assets owned or used by the Company.

     (c)   Neither the Company nor any of the Shareholders are or will be
required to give any notice to or obtain any Consent from any Person in

practice). All material properties and assets reflected in the Balance Sheet and

the case of real property, subject to any rights of way, building use
restrictions, exceptions, variances, reservations, or limitations of any nature

or the Interim Balance Sheet or on the accounting records of the Company as of

<PAGE>
Closing Date (which reserves are adequate and calculated consistent with past
practice and, in the case of the reserve as of the Closing Date, will not
represent a greater percentage of the Accounts Receivable as of the Closing Date
than the reserve reflected in the Interim Balance Sheet represented of the
Accounts Receivable reflected therein and will not represent a material adverse
change in the composition of such Accounts Receivable in terms of aging).
Subject to such reserves, each of the Accounts Receivable either has been or
will be collected in full, without any set-off, within 120 days after the day on
which it first becomes due and payable.  There is no contest, claim, or right of
set-off, other than returns in the Ordinary Course of Business, under any
Contract with any obligor of an Accounts Receivable relating to the amount or
validity of such Accounts Receivable. Part 3.8 of the Disclosure Letter contains
a complete and accurate list of all Accounts Receivable as of the date of the
Interim Balance Sheet, which list sets forth the aging of such Accounts
Receivable.

net realizable value in the Balance Sheet or the Interim Balance Sheet or on the
accounting records of the Company as of the Closing Date, as the case may be.
All inventories not written off have been priced at the lower of cost or market.
The quantities of each item of inventory (whether raw materials, work-in-
process, or finished goods) are not excessive, but are reasonable in the present
circumstances of the Company.

3.10 No Undisclosed Liabilities

The Company has no liabilities or obligations of any nature (whether known or
unknown and whether absolute, accrued, contingent, or otherwise) except for
liabilities or obligations otherwise disclosed herein or reflected or reserved

liabilities incurred in the Ordinary Course of Business since the respective
dates thereof.

          except such Taxes, if any, as are listed in Part 3.11 of the
          Disclosure Letter and are being contested in good faith and as to
          which adequate reserves (determined in accordance with GAAP) have been
          provided in the Balance Sheet and the Interim Balance Sheet.

     (b)  The United States federal and state income Tax Returns of the Company
          subject to such Taxes have been audited by the IRS or relevant state

     (c)  The charges, accruals, and reserves with respect to Taxes on the books
          of the Company are adequate (determined in accordance with GAAP) and

          that the Company is or was required by Legal Requirements to withhold

Since the date of the Interim Balance Sheet, there has not been any material
adverse change in the business, operations, properties, assets, results, working
capital position or condition (financial or other) of the Company, and no event

                or Sec. 4999; nor will the Company be required to "gross up" or
                otherwise compensate any such person because of the imposition

certificate or document delivered pursuant to this Agreement will survive the

representation, warranty, covenant, or obligation. The waiver of any condition

constituting a breach of any representation, warranty or covenant of another

other party for indemnification hereunder will be submitted after Closing shall
notify such other party of such facts or occurrences prior to Closing; provided,

          real property), or other damage of or to any Person, including any
          employee or former employee of the Company or any other Person for
          whose conduct it is or it may be held responsible, in any way arising
          from or allegedly arising from any Hazardous Activity conducted or
          allegedly conducted with respect to the Facilities or the operation of
          the Company prior to the Effective Time of the Merger, or from
          Hazardous Material that was (i) present on or before the Effective
          Time of the Merger, on or at the Facilities (or present on any other
          property, if such Hazardous Material emanated or allegedly emanated
          from any of the Facilities and was present on any of the Facilities on
          or prior to the Closing Date) or (ii) Released or allegedly Released
          by the Company or any other Person for whose conduct it is or it may
          be held responsible, at any time on or prior to the Effective Time of
          the Merger.

The procedure described in Section 11.6 will apply to any claim solely for
monetary damages relating to a matter covered by this Section 11.2.  The
remedies provided in this Article 11 will  the exclusive remedy of any party
hereto for any breach of or failure of performance required hereunder by any
other party hereto; provided, however, that any right or remedy of a party
hereto by reason of the fraud or intentional Breach of any other party hereto
shall not be so limited.

11.3 Indemnification and Payment of Damages by UNIT

UNIT will indemnify and hold harmless the Shareholders ("Indemnified Persons"),
and will pay to the Shareholders the amount of any Damages arising, directly or
indirectly, from or in connection with (a) any Breach of any representation or
warranty made by UNIT or UDC in this Agreement or in any certificate delivered
by UNIT pursuant to this Agreement, (b) any Breach by UNIT or UDC of any
covenant or obligation of UNIT or UDC in this Agreement, or (c) any claim by any
Person for brokerage or finder's fees or commissions or similar payments based
upon any agreement or understanding alleged to have been made by such Person
with UNIT (or any Person acting on its behalf) in connection with any of the
Contemplated Transactions.

11.4 Limitations

     (a)  If the Merger occurs, the Shareholders will have no liability (for
          indemnification or otherwise) with respect to any representation or
          warranty, or covenant or obligation to be performed and complied with
          prior to the Effective Time of the Merger, other than those in
          Sections 3.3, 3.11, and 3.13, unless on or before the date which is
          two years from the Effective Time of the Merger UNIT notifies the
          Shareholders of a claim specifying the factual basis of that claim in
          reasonable detail to the extent then known by UNIT.  A claim with
          respect to Section 3.3, 3.11 or 3.13, or a claim for indemnification
          or reimbursement not based upon any representation or warranty or any
          covenant or obligation to be performed and complied with prior to the
          Effective Time of the Merger, may be made at any time. If the Merger
          occurs, neither UNIT nor UDC will have any liability (for






                                                                          57

<PAGE>
          indemnification or otherwise) with respect to any representation or
          warranty, or covenant or obligation to be performed and complied with
          prior to the Effective Time of the Merger, unless on or before the
          date which is two years from the Effective Time of the Merger the
          Shareholders notify UNIT of a claim specifying the factual basis of
          that claim in reasonable detail to the extent then known by the
          Shareholders.  Notwithstanding the foregoing and the provisions of the
          last sentence of Section 11.2, if any party hereto shall make a claim
          (whether under state or federal securities laws or otherwise) against
          any other party hereto under or with respect to this Agreement or any
          of the transactions contemplated hereby after the expiration of such
          two-year period which is determined to be valid because it is not
          subject to such two-year period, such other party shall have the right
          to assert any claim under this Article 11 even though the two-year
          limitation period has expired.

     (b)  Shareholders will have no liability under this Article 11 until the
          total of all Damages with respect to such matters exceeds $100,000,
          and then only for the amount by which such Damages exceed $100,000.
          However, this paragraph (b) will not apply to any Breach of any of
          Shareholders' or the Company's representations and warranties of
          which any Shareholder had Knowledge at any time prior to the date on
          which such representation and warranty is made or any intentional
          Breach by the Company or any Shareholder of any covenant or
          obligation, and Shareholders will be jointly and severally liable for
          all Damages with respect to such Breaches.

     (c)  UNIT will have no liability under this Article 11 until the total of
          all Damages with respect to such matters exceeds $100,000, and then
          only for the amount by which such Damages exceed $100,000. However,
          this paragraph (c) will not apply to any Breach of any of UNIT's
          representations and warranties of which UNIT had Knowledge at any
          time prior to the date on which such representation and warranty is
          made or any intentional Breach by UNIT of any covenant or obligation,
          and UNIT will be liable for all Damages with respect to such Breaches.

     (d)  Any claim for indemnification shall be adjusted to take into account
          the receipt of any insurance proceeds by the Indemnified Parties
          incident to the matter giving rise to such claim for indemnification
          or to the indemnification payment hereunder.  The Indemnified Parties
          agree that they will make a claim against any applicable insurance
          policy available to the Indemnified Parties, and the Indemnified
          Parties may provide notice of but will not proceed further against the
          indemnifying Person for payment of Damages until any related insurance
          claim has been denied.  The Indemnified Parties will not be required
          to pursue any other remedies against any insurance policy or carrier
          if a claim is denied.  To the extent the Indemnified Parties elect not
          to further pursue any claim, the indemnifying Person shall be entitled
          to pursue such claim.  Any action by the indemnifying Person shall not
          affect or delay the rights of the Indemnified Parties to proceed
          against the indemnifying Person for payment of Damages.

11.5 Right of Set-Off

Upon at least 20 days' notice to the Shareholders specifying in reasonable
detail the basis for such set-off, UNIT may set off any amount to which it or
UDC may be entitled under this Article 11 against amounts otherwise payable

                                                                          58
<PAGE>
under the Promissory Notes.   Neither the exercise of nor the failure to
exercise such right of set-off will constitute an election of remedies or limit
UNIT in any manner in the enforcement of any other remedies that may be
available to it.

11.6 Procedure for Indemnification--Third Party Claims

     (a)  Promptly after receipt by an Indemnified Person under Section 11.2 or
          Section 11.3, of notice of the commencement of any Proceeding against
          it, such Indemnified Person will, if a claim is to be made against an
          indemnifying Person under such Section, give notice to the
          indemnifying Person of the commencement of such claim, but the failure
          to notify the indemnifying Person will not relieve the indemnifying
          Person of any liability that it may have to any Indemnified Person,
          except to the extent that the indemnifying Person demonstrates that
          the defense of such action is prejudiced by the Indemnified Person's
          failure to give such notice.

     (b)  If any Proceeding referred to in Section 11.6(a) is brought against an
          Indemnified Person and it gives notice to the indemnifying Person of
          the commencement of such Proceeding, the indemnifying Person will,
          unless the claim involves Taxes, be entitled to participate in such
          Proceeding and, to the extent that it wishes (unless (i) the
          indemnifying Person is also a party to such Proceeding and the
          Indemnified Person determines in good faith that joint representation
          would be inappropriate, or (ii) the indemnifying Person fails to
          provide reasonable assurance to the Indemnified Person of its
          financial capacity to defend such Proceeding and provide
          indemnification with respect to such Proceeding), to assume the
          defense of such Proceeding with counsel satisfactory to the
          Indemnified Person and, after notice from the indemnifying Person to
          the Indemnified Person of its election to assume the defense of such
          Proceeding, the indemnifying Person will not, as long as it diligently
          conducts such defense, be liable to the Indemnified Person under this
          Article 11 for any fees of other counsel or any other expenses with
          respect to the defense of such Proceeding, in each case subsequently
          incurred by the Indemnified Person in connection with the defense of
          such Proceeding, other than reasonable costs of investigation. If the
          indemnifying Person assumes the defense of a Proceeding, (i) no
          compromise or settlement of such claims  may be effected by the
          indemnifying Person without the Indemnified Person's consent unless
          (A) there is no finding or admission of any violation of Legal
          Requirements or any violation of the rights of any Person and no
          effect on any other claims that may be made against the Indemnified
          Person, and (B) the sole relief provided is monetary damages that are
          paid in full by the indemnifying Person; and (ii) the Indemnified
          Person will have no liability with respect to any compromise or
          settlement of such claims effected without its consent.

     (c)  Notwithstanding the foregoing, if an Indemnified Person determines in
          good faith that there is a reasonable probability that a Proceeding
          may adversely affect it or its Related Persons other than as a result
          of monetary damages for which it would be entitled to indemnification
          under this Agreement, the Indemnified Person may, by notice to the
          indemnifying Person, assume the exclusive right to defend, compromise,
          or settle such Proceeding, but the indemnifying Person will not be

                                                                          59

<PAGE>
          bound by any determination of a Proceeding so defended or any
          compromise or settlement effected without its consent (which may not
          be unreasonably withheld).

     (d)  The Shareholders hereby consent to the non-exclusive jurisdiction of
          any court in which a Proceeding is brought against any Indemnified
          Person for purposes of any claim that an Indemnified Person may have
          under this Agreement with respect to such Proceeding or the matters
          alleged therein, and agree that process may be served on the
          Shareholders with respect to such a claim anywhere in the world.

11.7 Participation

The Person not controlling the defense of a Proceeding shall have the right to
be represented by advisory counsel and accountants (at its own expense) in
connection with any Proceeding, and shall be kept reasonably informed by the
defending party of the status of such Proceeding at reasonable times at all
stages thereof, whether or not such party is so represented.  The indemnifying
Person and Indemnified Persons agree to make available to each other, their
counsel and accountants all information and documents reasonably available to
them which relate to such action, suit or proceeding, and agree to render to
each other such assistance as they may reasonably require of each other in order
to ensure the proper and adequate defense of any such Proceeding.

11.8 Procedure for Indemnification--Other Claims

A claim for indemnification for any matter not involving a third-party claim may
be asserted by notice to the party from whom indemnification is sought.

                             ARTICLE 12
                        REGISTRATION RIGHTS

12.1 Registration of Securities

     (a)  As used in this Article 12, the following terms have the meanings set
forth below:

"Disadvantageous Condition" has the meaning set forth in Section 12.1(b)(iv).

"Holders" means the Shareholders or any person who becomes a holder of Subject
Securities after the Merger as a result of a No-Sale Transaction.

"No-Sale Transaction" means a transfer from a Holder of Subject Securities that
does not constitute a "sale" (as such term is understood and defined under the
Securities Act), including without limitation a distribution from a Holder that
is a corporation, partnership, joint venture, limited liability company,
association or trust to the owner of a beneficial interest in such Holder.

"Registration Expenses" has the meaning set forth in Section 12.1(e).

"Registration Termination Date" means the second anniversary of the date when
the Shelf Registration Statement is first declared effective by the Commission.





                                                                          60

<PAGE>
"Shelf Registration Statement" means a registration statement on Form S-3 filed
with the Commission under the Securities Act.

"Subject Securities"  means the shares of UNIT Common Stock issued incident to
the Merger to Holders and any common stock or other security issued or issuable
as a dividend or other distribution with respect to, or in exchange for, or upon
conversion or in replacement of, any of such UNIT Common Stock.

"Suspension Notice" has the meaning set forth in Section 12.1(b)(iv).

     (b)  (i)   If the Merger occurs, as promptly as practicable thereafter (but
in no event more than 20 days thereafter, subject to UNIT's right to extend such
time in the event that there exists any Disadvantageous Condition which would
permit UNIT to issue a Suspension Notice if the Shelf Registration Statement
were already effective), UNIT will, on one occasion only, prepare and file with
the Commission a Shelf Registration Statement for the purpose of registering the
resale in the market from time to time of the Subject Securities by Holders or
by potential assignees of such Holders to which all or a portion of such
Holders' Subject Securities may be transferred in a No-Sale Transaction.

          (ii)  UNIT will use its Best Efforts to have the Shelf Registration
Statement promptly declared effective by the Commission and thereafter to
maintain the effectiveness of the Shelf Registration Statement and to maintain
such Shelf Registration Statement "current" (as below defined) at all times
until the Registration Termination Date.  UNIT shall promptly give written
notice to the Holders when the Registration Statement has been declared
effective by the Commission and is available for use by Holders for the resale
of Subject Securities.

          (iii) The Shelf Registration Statement shall not be considered to be
"current" at any time when, by reason of occurrence of any event or by reason of
the passage of time, the Shelf Registration Statement does not meet the
requirements of Section 10, Section 12(2) or Section 17 of the Securities Act,
or the Shelf Registration Statement contains an untrue statement of a material
fact or omits to state any material fact required to be stated therein or
necessary to make the statements therein not misleading.  The Shelf Registration
Statement shall disclose that Holders may elect to resell Subject Securities
without registration of such sales under the Shelf Registration Statement, by
making such sales under and as permitted by Rules 144 or 145, as applicable, of
the Commission under the Securities Act.

          (iv)  If at any time or times after the Shelf Registration Statement
is declared effective by the Commission, UNIT determines that the offering of
UNIT Common Stock under the Shelf Registration Statement would be significantly
disadvantageous to UNIT because of, or improper in view of (or improper without
disclosure in the prospectus included in the Shelf Registration Statement of),
the existence or anticipation of a material financing, merger, acquisition
or other material transaction or event involving UNIT or its Subsidiaries that
has not been publicly disclosed, the unavailability of any required financial








                                                                          61

<PAGE>
statements for reasons substantially beyond the control of the UNIT, or other
similar events or conditions involving UNIT or its Subsidiaries that have not
been publicly disclosed (a "Disadvantageous Condition"), UNIT shall be entitled
to either suspend the effectiveness of the Shelf Registration Statement with the
Commission or suspend the availability of the Shelf Registration for resales of
Subject Securities by Holders, or may take both such actions, and shall promptly
notify all Holders thereof by delivery of written notice (a "Suspension
Notice"); provided, however, that UNIT's obligation to maintain the Shelf
Registration Statement current under this Section 12.1(b) shall not be suspended
by reason of UNIT's failure to disclose information at a time when public
disclosure of such information is required by law. Upon receipt of a Suspension
Notice, Holders shall immediately discontinue the use of the Shelf Registration
Statement for any purpose until notified by UNIT that the Shelf Registration
Statement is current and available for use by Holders for sales of Subject
Securities.  UNIT shall not be entitled to suspend the effectiveness of the
Shelf Registration State 60 consecutive days, or (B) 180 days within any twelve
month period. As promptly as practicable disclosed or the UNIT determines that
the Disadvantageous Condition no longer exists, UNIT shall amend or supplement
the Shelf Registration Statement to the extent necessary to make the Shelf
Registration Statement current, and shall give prompt written notice to all
Holders when the Shelf Registration Statement is again available for resales of
Subject Securities.

          (v)   UNIT shall promptly notify all Holders of Subject Securities of,
and confirm in writing, the issuance by the Commission of any stop order
suspending the effectiveness of the Shelf Registration Statement or the
initiation of any proceedings for that purpose.  UNIT shall use its Best
Efforts to obtain the withdrawal of any order suspending the effectiveness of
the Shelf Registration Statement at the earliest possible time.

          (vi)  UNIT will cause all of the Subject Securities to be listed on
each securities exchange on which similar securities issued by UNIT are then
listed no later than the effective date of the Shelf Registration Statement.

     (c)  UNIT will indemnify and hold harmless each Holder, each of such
Holder's officers, directors, partners, or members, as the case may be, and each
person controlling such Holder, with respect to which registration or
qualification of Subject Securities has been effected pursuant to Article 12
against all claims, losses, damages, and liabilities, joint or several (or
actions in respect thereof), arising out of or based upon any untrue statement
(or alleged untrue statement) of a material fact contained in the Shelf
Registration Statement, prospectus, or offering circular, or in any document
incorporated by reference in any of the foregoing, or arising out of or based
upon any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or any violation by UNIT of any rule or regulation promulgated under
the Securities Act applicable to UNIT and relating to action or inaction
required of UNIT in connection with the Shelf Registration, each of such
Holder's officers, directors, partners, or members, as the case may be, and each
person controlling such Holder, for any legal and any other expenses reasonably
incurred in connection with investigating or defending any such claims, loss,
damage, liability or action; PROVIDED, however, that UNIT will not be liable in
any such case to the extent that any such claim, loss, damage, liability or
expense arises out of or is based upon any untrue statement or omission based
upon written information furnished to UNIT by such Holder specifically for


                                                                          62

<PAGE>
inclusion in any such registration statement, prospectus or offering circular.
The obligations of UNIT under the foregoing indemnity agreement shall survive
the completion of the offering of Subject Securities under the Shelf
Registration Statement .

     (d)  Each Holder with respect to which registration or qualification of
Subject Securities has been effected pursuant to this Article 12 will indemnify
and hold harmless UNIT, each of UNIT's of officers, directors, and each person
controlling UNIT, against all claims, losses, damages, and liabilities, joint or
several (or actions in respect thereof), arising out of or based upon any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, or offering circular, or in any document
incorporated by reference in any of the foregoing, or arising out of or based
upon any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or any violation by such Holder of any rule or regulation
promulgated under the Securities Act or Exchange Act applicable to such Holder
and relating to action or inaction required of such Holder in connection with
any such registration or qualification, and will promptly reimburse UNIT, each
of UNIT's officers, directors, and each person controlling UNIT, for any legal
and any other expenses reasonably incurred in connection with investigating or
defending any such claims, loss, damage, liability or action; PROVIDED, however,
that such Holder will not be liable in any such case to the extent that any such
claim, loss, damage, liability or expense does not arise out of or is not based
upon any untrue statement or omission based upon written information furnished
by such Holder specifically for inclusion in any such registration statement,
prospectus or offering circular. The obligations of Holders under the foregoing
indemnity agreement shall survive the completion of the offering of Subject
Securities under any registration statement provided for in this Article 12.

     (e)  All expenses incident to UNIT's performance of or compliance with this
Section 11.1, including, without limitation, all registration and filing fees,
fees and expenses of compliance with securities or blue sky laws (including fees
and disbursements of counsel in connection with blue sky qualifications of the
Subject Securities), rating agency fees, printing expenses, messenger and
delivery expenses, internal expenses (including, without limitation, all
salaries and expenses of its of officers and employees performing legal or

independent certified public accountants (including the expense of any special
audit or comfort letters required by or incident to such performance),
securities act liability insurance (if UNIT elects to obtain such insurance),
the fees and expenses of any special experts retained by UNIT in connection with
such registration, and fees and expenses of other persons retained by UNIT, in
connection with each registration hereunder (but not including discounts,
commissions, fees or expenses payable to underwriters that are attributes or the
fees and expenses of counsel for any selling Holder) (collectively, the
"Registration Expenses") will be borne by UNIT.

     (f)  UNIT will also take such action as may be required to be taken under
applicable blue sky laws in connection with the issuance of UNIT Common Stock
pursuant to this Agreement and in connection with resale of Subject Securities
by Holders pursuant to the Shelf Registration Statement; PROVIDED that UNIT will
not be required to become qualified as a foreign corporation in any
jurisdiction.
                                                                          63

<PAGE>
     (g)  Notwithstanding anything to the contrary in this Article 12 or
elsewhere in this Agreement, each of the Shareholders agrees with UNIT that
during the one-year period beginning with the date of the Closing, he, she or it
will not sell an amount of shares of UNIT Common Stock in the public market
which exceeds 1% of the total number of shares of UNIT Common Stock outstanding
during any three month period without the prior written consent of, which
consent may be withheld in UNIT's absolute discretion.

13.4 Arbitration

     (a)  The parties shall attempt in good faith to resolve any dispute arising
          out of or relating to this Agreement or any agreement entered into
          pursuant to this Agreement promptly by negotiation between  persons
          who have authority to settle the controversy.  Any party may give the
          other party written notice of any dispute not resolved in the normal
          course of business.  Within 15 days after delivery of the notice, the
          receiving party shall submit to the other a written response.  The
          notice and the response shall include (a) a statement of each party's
          position and a summary of arguments supporting that position, and (b)
          if the party is a company, the name and title of the executive who
          will represent that party and of any other person who will accompany
          the executive.  Within 30 days after delivery of the disputing party's
          notice, the both parties shall meet at a mutually acceptable time and
          place, and thereafter as often as they reasonably deem necessary, to
          attempt to resolve the dispute.  All reasonable requests for
          information made by one party to the other will be honored.

          All negotiations pursuant to this clause are confidential and shall be
          treated as compromise and settlement negotiations for purposes of
          applicable rules of evidence.

     (b)  Any dispute arising out of or relating to this Agreement or any
          agreement entered into pursuant to this Agreement or the breach,
          termination or validity thereof which has not been resolved by
          negotiation as provided herein within 45 days of the disputing party's
          notice, or if the parties failed to meet, shall be settled by
          arbitration conducted expeditiously in accordance with the Center for
          Public Resources Rules for Non-Administered Arbitration of Business
          Disputes by a sole arbitrator.  The arbitration shall be governed by
          the United States Arbitration Act, 9 U.S.C. Sec. 1-16, and judgment
          upon the award rendered by the arbitrators may be entered by any court
          having jurisdiction thereof.  The place of arbitration shall be Tulsa,
          Oklahoma, unless otherwise agreed to by the parties hereto.  The
          arbitrator is not empowered to award consequential, indirect, third
          party costs, special, punitive, or exemplary damages, and each party
          hereby irrevocably waives such damages.



                                                                          65

<PAGE>
     (c)  Notwithstanding anything in this section to the contrary, this section
          shall not apply in the event any claim, suit, demand, or proceeding
          (collectively, a "Claim") is asserted in a court of law against one or
          all parties hereto by a third party and any party hereto asserts, in
          such legal proceedings, the provisions of this Agreement against the
          other either as a defense to such Claim or as a basis for
          indemnification against such Claim.  Each of the parties consents to
          the jurisdiction of any such court (and of the appropriate appellate
          courts) in any such action or proceeding and waives any objection to
          venue laid therein. Process in any action or proceeding referred to in
          this subparagraph (c) may be served on any party anywhere in the
          world.

                         UNIT CORPORATION
                         PROMISSORY NOTE



$______________                          Date:  November 20, 1997


     Unit Corporation, a Delaware corporation, hereinafter referred to as the
"Company", for value received, hereby promises to pay to ________________, the
principal sum of $__________ together with interest on the unpaid principal
amount as hereinafter provided, both principal and interest being payable at the
address of the holder on the records of the Company, in such coin or currency of
the United States of America as at the time of payment shall be legal tender for
public and private debts.

     Interest shall accrue on the outstanding unpaid balance of principal due
hereunder at an annual percentage rate equal to the rate from time to time
announced by The Chase Manhattan Bank, N.A., New York, New York (the "Bank") as
its prime commercial rate for United States dollar loans made in the United
States (the "Prime Rate").  Any change in the interest rate hereon resulting
from a change in the Prime Rate shall be and become effective as of and on the
date of the announcement by the Bank of the change in such Prime Rate.
Principal payments equal to one fifth of the original principal amount hereof
together with accrued but unpaid interest shall be payable on January 2, 1999
and on January 2 of each of the next four successive calendar years thereafter.

     This Note is one of a series of Notes (the "Notes") of even date herewith
in the aggregate original principal amount of [$5,000,000] issued pursuant to
the terms of that certain Agreement and Plan of Merger dated as of November 20,
1997 (the "Agreement") entered into by and between the Company, Unit Drilling
Company ("UDC"), Hickman Drilling Company ("HDC") and each of the shareholders
of HDC including the payee named above and the related Certificate of Merger
filed with the Office of the Secretary of State of Oklahoma pursuant to which
HDC was merged with and into UDC, each of which rank on a parity with the others
with respect to the priority of claims for payment.

     Notwithstanding anything in this Note to the contrary, the principal amount
and interest due hereunder is subject to offset or reduction in the amount of
and to the extent of any liability or obligation that the payee named above may
have to the Company, UDC or any other Indemnified Person under Article 11 of the
Agreement.  Should the named payee become liable for any amounts under such
Article 11 (any such amounts being referred to herein as "Payee Liability"), the
Company shall provide at least 20 days' written notice thereof to said payee and
the amount of the next installment or installments of interest and principal due
hereunder shall be reduced by the amount of such Payee Liability.  The amount of
such Payee Liability shall be applied first to the amount of accrued but unpaid









<PAGE>
interest due hereunder and the balance shall then be applied to reduce the
amount of the principal due hereunder, all as of the date of the notice of the
Company to the named payee hereof.

     The total amount of interest payable hereunder is limited to that amount of
interest that may be lawfully charged to the undersigned under the laws of the
State of Oklahoma.  It is the intent of the payee and the undersigned to conform
strictly to the usury laws of the State of Oklahoma, and any interest on the
principal sum hereof in excess of that allowed by any said usury laws shall be
subject to reduction to the maximum amount of interest allowed under said laws.
If any interest in excess of the maximum amount of interest allowable by said
usury laws is inadvertently paid to the holder hereof at any time, any such
excess interest shall be refunded by the holder to the party or parties entitled
to the same after receiving notice of payment of such excess interest.

     In the event one or more of the Events of Default (as defined below) shall
have occurred and be continuing, the holder hereof may declare the principal and
interest accrued hereunder to be due and payable immediately, and upon any such
declaration the same shall become and shall be immediately due and payable,
anything in this Note contained to the contrary notwithstanding.  An "Event of
Default" shall be and consist of any of the following events:

          (a)  any default in the payment of the principal or interest when due
     hereunder and such continuance of default for a period of five days; or

          (b)  a court having jurisdiction in the premises shall enter a decree
     or order for relief in respect of the Company in an involuntary case under
     any applicable bankruptcy, insolvency or similar law now or hereinafter in
     effect, or appointing a receiver, liquidator, assignee, custodian, trustee,
     sequestrator (or similar official) of the Company or for any substantial
     part of its property, or ordering the winding-up or liquidation of its
     affairs, and such decree or order shall remain unstayed and in effect for a
     period of one hundred twenty (120) consecutive days; or

          (c)  the Company shall commence a voluntary case under any applicable
     bankruptcy, insolvency or similar law now or hereinafter in effect, or
     shall consent to the entry of an order for relief in an involuntary case
     under any such law, or shall consent to the appointment of or taking
     possession by a receiver, liquidator, assignee, trustee, custodian,
     sequestrator (or similar official) of the Company for any substantial part
     of its property, or shall make any general assignment for the benefit of
     creditors, or shall fail generally to pay its debts as they become due or
     shall take any corporate action in furtherance of any of the foregoing.

          (d)  any default by the Company in the performance of its obligations
     under the Agreement which is not corrected within 15 days of written notice
     of such default having been given to the Company by the holder.










                                   -2-

<PAGE>
Notwithstanding the foregoing, the holder of this Note may consent to or waive
any past default under the terms hereof and its consequences.

     The Company shall not have the right to prepay or redeem this Note in whole
or in part on any date prior to the maturity date of this Note without the
consent of the holder.

     In the event of a default the entire unpaid balance shall be immediately
due and payable, together with any past due interest at the rate of five
percentage points 5% per annum above the
Prime Rate.

     In the event of any controversy, claim or dispute between the parties
relating to the performance of this Note, including, without limitation, any
arbitration proceedings conducted with respect to any asserted set-off right for
Payee Liability, the prevailing party shall be entitled to recover from the non-
prevailing party all of its reasonable costs and expenses, including reasonable
attorneys' fees.

     IN WITNESS WHEREOF, Unit Corporation has caused this Note to be signed in
its corporate name by the signatures of its President and its Secretary and has
caused its corporate seal to be affixed hereto or imprinted hereon.

     DATED this _____ day of ______________________, 1997.
