                          AGREEMENT AND PLAN OF MERGER

         This Agreement and Plan of Merger, dated as of the 28th day of October,
1998 (the "Agreement"), is among Parker Drilling Company, a Delaware corporation
("Parker"), Saints Acquisition Company, a newly formed Delaware corporation and
a wholly owned subsidiary of Parker ("Sub"), and Superior Energy Services, Inc.,
a Delaware corporation ("Superior").

                                   WITNESSETH:

         WHEREAS, subject to and in accordance with the terms and conditions of
this Agreement, the respective Boards of Directors of Parker, Sub and Superior,
and Parker as sole stockholder of Sub, have approved the merger of Sub with and
into Superior (the "Merger"), whereby each issued and outstanding share of
common stock, par value $0.001 per share, of Superior ("Superior Common Stock")
not owned directly or indirectly by Superior will be converted into the right to
receive 0.90 of a share of common stock, par value $0.16 2/3 per share, of
Parker ("Parker Common Stock");

         WHEREAS, for federal income tax purposes, it is intended that the
Merger shall qualify as a reorganization within the meaning of Sections
368(a)(1)(A) and 368(a)(2)(E) of the Internal Revenue Code of 1986, as amended
(the "Code"), and this Agreement constitutes a plan of reorganization;

         WHEREAS, the Merger is intended to be treated as a "pooling of
interests" for accounting purposes; and

         WHEREAS, the parties hereto desire to set forth certain
representations, warranties and covenants made by each to the other as an
inducement to the consummation of the Merger;

         NOW, THEREFORE, in consideration of the premises and of the mutual
representations, warranties and covenants herein contained, the parties hereto
hereby agree as follows:

                                    ARTICLE I

                                   THE MERGER

         1.1 THE MERGER. Subject to and in accordance with the terms and
conditions of this Agreement and in accordance with the General Corporation Law
of the State of Delaware (the "DGCL"), at the Effective Time (as defined in
Section 1.3) Sub shall be merged with and into Superior. As a result of the
Merger, the separate corporate existence of Sub shall cease and Superior shall
continue as the surviving corporation (sometimes referred to herein as the
"Surviving Corporation"), and all the properties, rights, privileges, powers and
franchises of Superior and Sub shall vest in the Surviving Corporation, without
any transfer or assignment having occurred, and all debts, liabilities and
duties of Superior and Sub shall attach to the Surviving Corporation, all in
accordance with the DGCL.


<PAGE>   6



         1.2 CLOSING DATE. The closing of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Vinson & Elkins
L.L.P., 2300 First City Tower, 1001 Fannin Street, Houston, Texas 77002, as soon
as practicable after the satisfaction or waiver of the conditions set forth in
Section 6.1 or at such other time and place and on such other date as Parker and
Superior shall agree, or if no date has been agreed to, any date specified by
one party to the other upon three days' notice following satisfaction of the
conditions set forth in Section 6.1, provided that the other closing conditions
set forth in Article VI shall have been satisfied or waived at or prior to such
time. The date on which the Closing occurs is herein referred to as the "Closing
Date."

         1.3 CONSUMMATION OF THE MERGER. As soon as practicable on the Closing
Date, the parties hereto will cause the Merger to be consummated by filing with
the Secretary of State of Delaware a certificate of merger in such form as
required by, and executed in accordance with, the relevant provisions of the
DGCL. The "Effective Time" of the Merger (as that term is used in this
Agreement) shall mean such time as the certificate of merger is duly filed with
the Secretary of State of Delaware or at such later time (not to exceed 90 days
from the date the certificate is filed) as is specified in the certificate of
merger pursuant to the mutual agreement of Parker and Superior.

         1.4 EFFECTS OF THE MERGER. The Merger shall have the effects set forth
in the applicable provisions of the DGCL.

         1.5 CERTIFICATE OF INCORPORATION; BYLAWS. At the Effective Time, the
Certificate of Incorporation and Bylaws of Sub, as in effect immediately prior
to the Effective Time, shall be the Certificate of Incorporation and Bylaws,
respectively, of the Surviving Corporation, provided that they shall be amended
as of the Effective Time to reflect that the name of the Surviving Corporation
shall be "Superior Energy Services, Inc."

         1.6 DIRECTORS AND OFFICERS. The officers and directors of the Surviving
Corporation, each to hold office until their respective successors are duly
elected or appointed and qualified, shall be as set forth on Annex I attached
hereto.

         1.7 CONVERSION OF SUPERIOR COMMON STOCK.

             (a) As of the Effective Time, by virtue of the Merger and without
any action on the part of the holder of any shares of Superior Common Stock or
any shares of capital stock of Sub, and subject to Section 1.8(f), each share of
Superior Common Stock issued and outstanding immediately prior to the Effective
Time (other than shares to be canceled in accordance with Section 1.7(b)) shall
be converted into the right to receive 0.90 of a share of Parker Common Stock
(the "Merger Consideration"); provided, however, that if, between the date
hereof and the Effective Time, the outstanding shares of Parker Common Stock or
Superior Common Stock shall have been changed into a different number of shares
or a different class, by reason of any stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares,
the Merger Consideration shall be correspondingly adjusted to the extent
appropriate to reflect such stock dividend, subdivision, reclassification,
recapitalization, split, combination or exchange of shares. As of the Effective
Time, all such shares of Superior Common Stock shall no longer be outstanding
and shall automatically be canceled and retired and shall cease to exist, and
each holder of a


                                       -2-
<PAGE>   7
certificate representing any such shares of Superior Common Stock shall cease to
have any rights with respect thereto, except the right to receive the Merger
Consideration.

             (b) Each share of Superior Common Stock held in the treasury of
Superior and each share of Superior Common Stock owned by Sub, Parker or any
direct or indirect wholly owned subsidiary of Parker or of Superior immediately
prior to the Effective Time shall be canceled and extinguished without any
conversion thereof and no payment shall be made with respect thereto.

             (c) Each share of common stock of Sub issued and outstanding
immediately prior to the Effective Time shall be converted into one share of the
common stock, $.001 par value per share, of the Surviving Corporation.

         1.8 EXCHANGE OF CERTIFICATES.

             (a) From and after the Effective Time, (i) Parker shall make
available to a bank or trust company designated by Parker (the "Exchange
Agent"), for the benefit of the holders of shares of Superior Common Stock, for
exchange in accordance with this Section 1.8, through the Exchange Agent,
certificates evidencing such number of shares of Parker Common Stock issuable to
holders of Superior Common Stock in the Merger pursuant to Section 1.7. The
Exchange Agent shall, pursuant to irrevocable written instructions from Parker,
deliver the Parker Common Stock, together with any cash to be paid in lieu of
fractional interests in shares of Parker Common Stock pursuant to Section 1.8(f)
and any dividends or distributions related thereto (collectively, the "Exchange
Fund"), in exchange for certificates theretofore evidencing Superior Common
Stock surrendered to the Exchange Agent pursuant to Section 1.8(c). Except as
contemplated by Sections 1.8(f) and (g) hereof, the Exchange Fund shall not be
used for any other purpose.

             (b) As promptly as practicable after the Effective Time, Parker
shall cause the Exchange Agent to mail to each holder of a certificate or
certificates which immediately prior to the Effective Time represented
outstanding shares of Superior Common Stock (the "Certificates") (i) a letter of
transmittal (which shall be in customary form and shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon proper delivery of the Certificates to the Exchange Agent) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for the Merger Consideration.

             (c) Upon surrender to the Exchange Agent of a Certificate for
cancellation, together with such letter of transmittal, duly executed and
completed in accordance with the instructions thereto, and such other documents
as may be reasonably required pursuant to such instructions, the holder of such
Certificate shall be entitled to receive in exchange therefor (i) a certificate
representing that number of whole shares of Parker Common Stock, if any, to
which such holder is entitled pursuant to Section 1.7 and (ii) cash in lieu of
any fractional shares of Parker Common Stock to which such holder is entitled
pursuant to Section 1.8(f) and any dividends or other distributions to which
such holder is entitled pursuant to Section 1.8(d) (together, the "Additional
Payments"), and the Certificate so surrendered shall forthwith be canceled. In
the event of a transfer of ownership of shares of Superior Common Stock which is
not registered in the transfer records of Superior, the applicable Merger
Consideration and Additional Payments, if any, may be issued to


                                       -3-
<PAGE>   8
a transferee if the Certificate representing such shares of Superior Common
Stock is presented to the Exchange Agent, accompanied by all documents required
to evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid. Until surrendered as contemplated by this Section
1.8, each Certificate shall be deemed at all times after the Effective Time to
represent only the right to receive upon such surrender the Merger Consideration
with respect to the shares of Superior Common Stock formerly represented thereby
and Additional Payments, if any.

             (d) No dividends or other distributions declared or made after the
Effective Time with respect to Parker Common Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of Parker Common Stock the holder thereof is entitled to
receive upon surrender thereof, and no cash payment in lieu of any fractional
shares shall be paid to any such holder pursuant to Section 1.8(f), until the
holder of such Certificate shall surrender such Certificate. Subject to the
effect of escheat, tax or other applicable laws, following surrender of any such
Certificate, there shall be paid to the holder of the certificates representing
whole shares of Parker Common Stock issued in exchange therefor, without
interest, (i) promptly, the amount of any cash payable with respect to a
fractional share of Parker Common Stock to which such holder is entitled
pursuant to Section 1.8(f) and the amount of dividends or other distributions
with a record date after the Effective Time and theretofore paid with respect to
such whole shares of Parker Common Stock, and (ii) at the appropriate payment
date, the amount of dividends or other distributions, with a record date after
the Effective Time but prior to surrender and a payment date occurring after
surrender, payable with respect to such whole shares of Parker Common Stock.
After the Effective Time, each outstanding Certificate which theretofore
represented shares of Superior Common Stock shall, until surrendered for
exchange in accordance with this Section 1.8, be deemed for all purposes to
evidence ownership of the number of shares of Parker Common Stock into which the
shares of Superior Common Stock (which, prior to the Effective Time, were
represented thereby) shall have been so converted.

             (e) All shares of Parker Common Stock issued or cash paid upon
conversion of the shares of Superior Common Stock in accordance with the terms
hereof (including any cash paid pursuant to Section 1.8(d) or (f)) shall be
deemed to have been issued in full satisfaction of all rights pertaining to such
shares of Superior Common Stock.

             (f) Notwithstanding anything herein to the contrary, no
certificates or scrip evidencing fractional shares of Parker Common Stock shall
be issued in connection with the Merger, and any such fractional share interests
to which a holder of record of Superior Common Stock at the Effective Time would
otherwise be entitled will not entitle such holder to vote or to any rights of a
stockholder of Parker. In lieu of any such fractional shares, each holder of
record of Superior Common Stock at the Effective Time who but for the provisions
of this Section 1.8(f) would be entitled to receive a fractional interest of a
share of Parker Common Stock pursuant to the Merger shall be paid cash, without
any interest thereon, equal to the fraction of a share of Parker Common Stock to
which such holder would be entitled but for this provision multiplied by the
closing price of the Parker Common Stock on the New York Stock Exchange on the
Effective Date.

             (g) Any portion of the Exchange Fund (including any shares of
Parker Common Stock) which remains undistributed to the holders of Superior
Common Stock for six months after the Effective Time shall be delivered to
Parker, upon demand, and any holders of Superior Common Stock who have not
theretofore complied with Sections 1.7 and 1.8 shall thereafter look only to
Parker for the applicable Merger Consideration and any Additional Payments to
which they are entitled. Any portion of the Exchange Fund remaining unclaimed by
holders of shares of Superior Common Stock as of a date which is immediately
prior to such time as such amounts would otherwise escheat to or become property
of any governmental entity shall, to the extent permitted by applicable law,
become the property of Parker, free and clear of any claims or interest of any
person previously entitled thereto.

             (h) None of the Exchange Agent, Parker or the Surviving Corporation
shall be liable to any holder of Certificates for any shares of Parker Common
Stock (or dividends or distributions with respect thereto), or cash delivered to
a public official pursuant to any abandoned property, escheat or similar law.

             (i) Each of the Surviving Corporation and Parker shall be entitled
to deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of Certificates such amounts as it is required to deduct
and withhold with respect to the making of such payment under the Code, or any
provision of state, local or foreign tax law. To the extent that amounts are so
withheld by the Surviving Corporation or Parker, as the case may be, such
amounts withheld shall be treated for all purposes of this Agreement as having
been paid to the holder of the Certificates in respect of which such deduction
and withholding was made by the Surviving Corporation or Parker, as the case may
be.

             (j) If any Certificate shall have been lost, stolen or destroyed,
upon the making of an affidavit of that fact by the person claiming such
Certificate to be lost, stolen or destroyed and, if required by the Surviving
Corporation, the posting by such person of a bond, in such reasonable amount as
the Surviving Corporation may direct, as indemnity against any claim that may be
made against it with respect to such Certificate, the Exchange Agent will issue
in exchange for such lost, stolen or destroyed Certificate the Merger
Consideration and Additional Payments, if any.

             (k) If, at any time after the Effective Time, the Surviving
Corporation shall consider or be advised that any deeds, bills of sale,
assignments, assurances or any other actions or things are necessary or
desirable to vest, perfect or confirm of record or otherwise in the Surviving
Corporation its right, title or interest in, to or under any of the rights,
properties or assets of either of Sub or Superior acquired or to be acquired by
the Surviving Corporation as a result of, or in connection with, the Merger or
otherwise to carry out this Agreement, the officers of the Surviving Corporation
shall be authorized to execute and deliver, in the name and on behalf of each of
Sub and Superior or otherwise, all such deeds, bills of sale, assignments and
assurances and to take and do, in such names and on such behalves or otherwise,
all such other actions and things as may be necessary or desirable to vest,
perfect or confirm any and all right, title and interest in, to and under such
rights, properties or assets in the Surviving Corporation or otherwise to carry
out the purposes of this Agreement.

         1.9  STOCK TRANSFER BOOKS. At the Effective Time, the stock transfer
books of Superior shall be closed and there shall be no further registration of
transfers of shares of Superior Common Stock thereafter on the records of
Superior. On or after the Effective Time, any Certificates presented to the
Exchange Agent or Parker for any reason shall be converted into the Merger
Consideration and Additional Payments, if any.

         1.10 TAKING OF NECESSARY ACTION; FURTHER ACTION. The parties hereto
shall take all such reasonable and lawful action as may be necessary or
appropriate in order to effectuate the Merger as promptly as possible. If, at
any time after the Effective Time, any such further action is necessary or
desirable to carry out the purposes of this Agreement and to vest in the
Surviving Corporation all right, title and possession to all assets, property,
rights, privileges, powers and franchises of Superior or Sub, such corporations
shall direct their respective officers and directors to take all such lawful and
necessary action.

                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES

         2.1  REPRESENTATIONS AND WARRANTIES OF PARKER AND SUB. Parker and Sub
hereby jointly and severally represent and warrant to Superior that:

              (a) Organization and Compliance with Law. Each of Parker and its
         consolidated significant subsidiaries as defined in Rule 1.02 of
         Regulation S-X (the "Parker Subsidiaries") is a corporation, a limited
         liability company or a limited liability partnership duly organized,
         validly existing and in good standing under the laws of the
         jurisdiction in which it is chartered or organized and has all
         requisite corporate power and authority and all necessary governmental
         authorizations to own, lease and operate all of its properties and
         assets and to carry on its business as now being conducted, except
         where the failure to be so organized, existing or in good standing or
         to have such governmental authority would not have a material adverse
         effect on the financial condition, results of operations or business of
         Parker and the Parker Subsidiaries, taken as a whole (a "Parker MAE").
         A Parker MAE shall not be deemed to include material adverse changes
         affecting the contract drilling industry or the United States economy
         generally. Except as set forth in Section 2.1(a) of the disclosure
         letter delivered by Parker to Superior on the date hereof (the "Parker
         Disclosure Letter"), each of Parker and the Parker Subsidiaries is duly
         qualified as a foreign corporation to do business, and is in good
         standing, in each jurisdiction in which the property owned, leased or
         operated by it or the nature of the business conducted by it makes such
         qualification necessary, except in such jurisdictions where the failure
         to be duly qualified does not and would not, either individually or in
         the aggregate, have a Parker MAE. Each of Parker and the Parker
         Subsidiaries is in compliance with all applicable laws, judgments,
         orders, rules and regulations, domestic and foreign, except where
         failure to be in such compliance would not have a Parker MAE.

              (b) Capitalization.

                  (i)   The authorized capital stock of Parker consists of
              120,000,000 shares of Parker Common Stock, and 1,942,000 shares of
              preferred stock, par value $1.00 per share ("Parker Preferred
              Stock"). As of September 30, 1998, there were issued and
              outstanding 76,783,045 shares of Parker Common Stock, 482,044
              shares of Parker Common Stock were held as treasury shares, and no
              shares of Parker Preferred Stock were issued and outstanding but
              120,000 shares have been designated as Junior Participating
              Preferred Stock, par value $.01 per share. All issued shares of
              Parker Common Stock were validly issued and are fully paid and
              nonassessable and no holder thereof is entitled to preemptive
              rights. Except as set forth in Section 2.1(b) of the Parker
              Disclosure Letter, and except for shares reserved for issuance
              pursuant to Parker stock plans described in Section 2.1(b) of
              Parker Disclosure Letter and pursuant to the 5 1/2% Convertible
              Subordinated Debentures due 2004 (the "Convertible Debentures"),
              no shares of Parker Common Stock are reserved for issuance, and
              except for Parker's obligations under that certain Rights
              Agreement dated as of July 14, 1998 between Parker and Norwest
              Bank Minnesota, N.A., as Rights Agent, there are no contracts,
              agreements, commitments or arrangements obligating Parker (i) to
              offer, sell, issue or grant any capital stock of Parker or (ii) to
              redeem, purchase or acquire, or offer to purchase or acquire, any
              outstanding capital stock of Parker or to grant any lien on any
              shares of capital stock of Parker. All shares of Parker Common
              Stock to be issued pursuant to the Merger, when issued in
              accordance with this Agreement, will be validly issued, fully paid
              and nonassessable and will not violate the preemptive rights of
              any person. Except as set forth in Section 2.1(b) of the Parker
              Disclosure Letter, Parker is not a party to, and is not aware of,
              any voting agreement, voting trust or similar agreement or
              arrangement relating to any class or series of its capital stock,
              or any agreement or arrangement providing for registration rights
              with respect to any capital stock or other securities of Parker.

                  (ii)  As of September 30, 1998, there were outstanding options
              to purchase 5,597,500 shares of Parker Common Stock pursuant to
              the plans and agreements referenced in Section 2.1(b)(i) above
              ("Parker Options"), and 11,371,020 shares were reserved for
              issuance upon conversion of the Convertible Debentures.

                  (iii) As of the date hereof, the authorized capital stock of
              Sub consists of 1,000 shares of common stock, par value $0.01 per
              share, all of which were validly issued and are fully paid and
              nonassessable and are owned by Parker.

                  (iv)  Except as set forth in Section 2.1(b) of the Parker
              Disclosure Letter, all outstanding shares of the Parker
              Subsidiaries (A) are owned by Parker or a wholly owned subsidiary
              of Parker, free and clear of all liens, charges, encumbrances,
              adverse claims and options of any nature, (B) were duly authorized
              and validly issued and are fully paid and nonassessable, and (C)
              have not been issued in violation of any preemptive rights. Except
              as set forth in Section 2.1(b) of the Parker Disclosure


                                       -7-
<PAGE>   12
              Letter, there are not now, and at the Effective Time there will
              not be, any outstanding options, warrants, scrip, rights to
              subscribe for, calls or commitments of any character whatsoever
              relating to, or securities or rights convertible into or
              exchangeable for, shares of any class of capital stock of the
              Parker Subsidiaries, or contracts, understandings or arrangements
              to which Parker or a Parker Subsidiary is a party, or by which any
              of them is or may be bound, to issue additional shares of capital
              stock or options, warrants, scrip or rights to subscribe for, or
              securities or rights convertible into or exchangeable for, any
              additional shares of capital stock of any Parker Subsidiary.

              (c) Authorization and Validity of Agreement. Parker and Sub have
         all requisite corporate power and authority to enter into this
         Agreement and to perform their obligations hereunder. The execution and
         delivery by Parker and Sub of this Agreement and the consummation by
         each of them of the transactions contemplated hereby have been duly
         authorized by all necessary corporate action on the part of Parker and
         Sub (other than, with respect to the approval of the issuance of shares
         of Parker Common Stock pursuant to the Merger (the "Share Issuance")
         and the approval of an amendment to Parker's Restated Certificate of
         Incorporation to increase the authorized share capital (the "Charter
         Amendment"), by the holders of a majority of the outstanding shares of
         Parker Common Stock in accordance with Section 5.1(b)). On or prior to
         the date hereof, the Board of Directors of Parker has determined to
         recommend approval of the Share Issuance and the Charter Amendment to
         the stockholders of Parker, and such determination is in effect as of
         the date hereof. This Agreement has been duly executed and delivered by
         Parker and Sub and is the valid and binding obligation of Parker and
         Sub, enforceable against Parker and Sub in accordance with its terms,
         except as the same may be limited by legal principles of general
         applicability governing the application and availability of equitable
         remedies.

              (d) No Approvals or Notices Required; No Conflict with Instruments
         to which Parker or any of the Parker Subsidiaries is a Party. Neither
         the execution and delivery of this Agreement nor the performance by
         Parker or Sub of their respective obligations hereunder, nor the
         consummation of the transactions contemplated hereby by Parker and Sub,
         will (i) except for the requirement of a Charter Amendment to increase
         the authorized share capital, conflict with the certificate of
         incorporation or bylaws or other equivalent organizational documents of
         Parker or the charter or bylaws of any of the Parker Subsidiaries; (ii)
         assuming satisfaction of the requirements set forth in clause (iii)
         below, violate any provision of law applicable to Parker or any of the
         Parker Subsidiaries; (iii) except for (A) requirements of federal or
         state securities laws, (B) requirements arising out of the
         Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"),
         (C) requirements of notice filings in such foreign jurisdictions as may
         be applicable, and (D) the filing of a certificate of merger by Sub in
         accordance with the DGCL, require any consent or approval of, or filing
         with or notice to, any public body or authority, domestic or foreign,
         under any provision of law applicable to Parker or any of the Parker
         Subsidiaries; or (iv) require any consent, approval or notice under, or
         violate, breach, be in conflict with or constitute a default (or an
         event that, with notice or lapse of time or both, would constitute a
         default) under, or permit the termination of any provision of, or
         result in the creation or

         
                                       -8-
<PAGE>   13
         imposition of any lien upon any properties, assets or business of
         Parker or any of the Parker Subsidiaries under, any note, bond,
         indenture, mortgage, deed of trust, lease, franchise, permit,
         authorization, license, contract, instrument or other agreement or
         commitment or any order, judgment or decree to which Parker or any of
         the Parker Subsidiaries is a party or by which Parker or any of the
         Parker Subsidiaries or any of their respective assets or properties is
         bound or encumbered, except (A) the approval by the stockholders of
         Parker in accordance with Section 5.1(b), (B) those that have already
         been given, obtained or filed, (C) those that are required pursuant to
         bank loan agreements, as set forth in Section 2.1(d) of the Parker
         Disclosure Letter, which will be obtained prior to the Effective Time,
         or (D) those that, in the aggregate, would not have a Parker MAE.

              (e) Commission Filings; Financial Statements. Parker and each of
         the Parker Subsidiaries have timely filed all reports, registration
         statements and other filings, together with any amendments required to
         be made with respect thereto, that they have been required to file with
         the Securities and Exchange Commission (the "Commission") under the
         Securities Act of 1933, as amended (the "Securities Act"), and the
         Securities Exchange Act of 1934, as amended (the "Exchange Act"). All
         reports, registration statements and other filings (including all
         notes, exhibits and schedules thereto and documents incorporated by
         reference therein) filed by Parker with the Commission since August 31,
         1996 through the date of this Agreement, together with any amendments
         thereto, are sometimes collectively referred to as the "Parker
         Commission Filings." As of the respective dates of their filing with
         the Commission, the Parker Commission Filings complied in all material
         respects with the Securities Act, the Exchange Act and the rules and
         regulations of the Commission thereunder, and did not contain any
         untrue statement of a material fact or omit to state a material fact
         required to be stated therein or necessary to make the statements made
         therein, in light of the circumstances under which they were made, not
         misleading.

              Each of the consolidated financial statements (including any
         related notes or schedules) included in the Parker Commission Filings
         was prepared in accordance with generally accepted accounting
         principles applied on a consistent basis (except as may be noted
         therein or in the notes or schedules thereto) and complied with all
         applicable rules and regulations of the Commission. Such consolidated
         financial statements fairly present the consolidated financial position
         of Parker and the Parker Subsidiaries as of the dates thereof and the
         results of operations, cash flows and changes in stockholders' equity
         for the periods then ended (subject, in the case of the unaudited
         interim financial statements, to normal year-end audit adjustments on a
         basis consistent with past periods).

              (f) Absence of Undisclosed Liabilities. Except as disclosed in
         Section 2.1(f) of the Parker Disclosure Letter or in the Parker
         Commission Filings, as of the date of this Agreement, neither Parker
         nor any of the Parker Subsidiaries has any liabilities that are
         reasonably likely to have, individually or in the aggregate, a Parker
         MAE, except liabilities which are accrued or reserved against in the
         consolidated balance sheet of Parker as of August 31, 1997 or May 31,
         1998, included in the Parker Commission Filings or reflected in the
         notes thereto. Neither Parker nor any Parker Subsidiary has incurred or
         paid any liability since May 31, 1998, except for liabilities incurred
         or paid (i) in the ordinary course


                                       -9-
<PAGE>   14
         of business consistent with past practice, (ii) in connection with
         transactions contemplated by this Agreement, or (iii) pursuant to
         transactions not prohibited by this Agreement.

              (g) Conduct of Business in the Ordinary Course; Absence of Certain
         Changes and Events. Since August 31, 1997, except as contemplated by
         this Agreement or as disclosed in the Parker Commission Filings filed
         with the Commission prior to the date hereof or as set forth in Section
         2.1(g) of the Parker Disclosure Letter, Parker and the Parker
         Subsidiaries have conducted their business only in the ordinary and
         usual course, and there has not been (i) any Parker MAE or any
         condition, event or development that reasonably may be expected to
         result in a Parker MAE; (ii) any material change by Parker in its
         accounting methods, principles or practices; (iii) any revaluation by
         Parker or any of the Parker Subsidiaries of any of their respective
         assets, including, without limitation, writing down the value of
         inventory or writing off notes or accounts receivable other than in the
         ordinary course of business; (iv) any declaration, setting aside or
         payment of any dividends or distributions in respect of Parker Common
         Stock, or any redemption, purchase or other acquisition of any of its
         securities or any securities of any of the Parker Subsidiaries; (v) any
         damage, destruction or loss (whether or not covered by insurance)
         materially adversely affecting the properties or business of Parker and
         the Parker Subsidiaries, taken as a whole; (vi) any increase in
         indebtedness for borrowed money other than borrowings under existing
         credit facilities or indebtedness incurred in the ordinary course of
         business; or (vii) any granting of a security interest in or lien on
         any material property or assets of Parker and the Parker Subsidiaries,
         taken as a whole, other than (A) liens for taxes not due and payable or
         which are being contested in good faith; (B) maritime liens and
         mechanics', warehousemen's and other statutory liens incurred in the
         ordinary course of business; (C) defects and irregularities in title
         and encumbrances which are not substantial in character or amount and
         do not materially impair the use of the property or asset in question;
         and (D) liens securing indebtedness incurred in the ordinary course of
         business (collectively, "Permitted Liens").

              (h) Tax Representation. Parker has no plan or intention to (i)
         liquidate the Surviving Corporation; (ii) merge the Surviving
         Corporation with or into another corporation; (iii) sell or otherwise
         dispose of the stock of the Surviving Corporation except for transfers
         or successive transfers to one or more corporations controlled (within
         the meaning of section 368(c) of the Code) in each case by the
         transferor corporation; (iv) cause the Surviving Corporation to issue
         additional shares of its capital stock that would result in Parker's
         losing control (within the meaning of section 368(c) of the Code), of
         the Surviving Corporation; (v) cause or permit the Surviving
         Corporation to sell or otherwise dispose of any of its assets or of any
         of the assets acquired from Sub except for dispositions made in the
         ordinary course of business or transfers or successive transfers to one
         or more corporations controlled (within the meaning of section 368(c)
         of the Code) in each case by the transferor corporation; or (vi)
         reacquire or cause any person related (as defined in Treas. Reg.

         Section 1.368-1(d)) or use a

         or will be entitled to any commission or broker's or finder's fee from
         any of the parties hereto in connection with any of the transactions
         contemplated herein, except fees to Jefferies & Company, Inc. and

         2.2  REPRESENTATIONS AND WARRANTIES OF SUPERIOR. Superior hereby
represents and warrants to Parker that:

              (a) Organization and Compliance with Law. Each of Superior and its
         consolidated subsidiaries (the "Superior Subsidiaries") is a
         corporation or a limited liability company duly organized, validly
         existing and in good standing under the laws of the jurisdiction in
         which it is chartered or organized and has all requisite corporate
         power and authority and all necessary governmental authorizations to
         own, lease and operate all of its properties and assets and to carry on
         its business as now being conducted, except where the failure to be so
         organized, existing or in good standing or to have such governmental
         authority would not have a material adverse effect on the financial
         condition, results of operations or business of Superior and the
         Superior Subsidiaries, taken as a whole (a "Superior MAE"). A Superior
         MAE shall not be deemed to include material adverse changes affecting
         the oilfield services industry or the United States economy generally.
         Except as set forth in Section 2.2(a) of the disclosure letter
         delivered by Superior to Parker on the date hereof (the "Superior
         Disclosure Letter"), each of Superior and the Superior Subsidiaries is
         duly qualified as a foreign corporation to do business, and is in good
         standing,


                                      -11-
<PAGE>   16
         in each jurisdiction in which the property owned, leased or operated by
         it or the nature of the business conducted by it makes such
         qualification necessary, except in such jurisdictions where the failure
         to be duly qualified does not and would not, either individually or in
         the aggregate, have a Superior MAE. Each of Superior and the Superior
         Subsidiaries is in compliance with all applicable laws, judgments,
         orders, rules and regulations, domestic and foreign, except where
         failure to be in such compliance would not have a Superior MAE.

              (b) Capitalization.

                  (i)   The authorized capital stock of Superior consists of
         40,000,000 shares of Superior Common Stock and 5,000,000 shares of
         preferred stock, par value $.01 per share ("Superior Preferred Stock").
         As of October 26, 1998, there were issued and outstanding 28,792,523
         shares of Superior Common Stock, 474,500 shares of Superior Common
         Stock were held as treasury shares and no shares of Superior Preferred
         Stock were issued and outstanding. All issued shares of Superior Common
         Stock were validly issued and are fully paid and nonassessable and no
         holder thereof is entitled to preemptive rights. Except as set forth in
         Section 2.2(b) of the Superior Disclosure Letter, Superior is not a
         party to, and is not aware of, any voting agreement, voting trust or
         similar agreement or arrangement relating to any class or series of its
         capital stock, or any agreement or arrangement providing for
         registration rights with respect to any capital stock or other
         securities of Superior.

                  (ii)  As of the date hereof, there were outstanding options
         (the "Superior Options") to purchase an aggregate of 1,726,500 shares
         of Superior Common Stock under the Amended and Restated Superior, Inc.
         1995 Stock Incentive Plan (the "Superior Stock Option Plan"). Other
         than as set forth in this Section 2.2(b) and in Section 2.2(b) (ii) of
         the Superior Disclosure Letter, there are not now, and at the Effective
         Time there will not be, any (A) shares of capital stock or other equity
         securities of Superior outstanding other than Superior Common Stock
         issuable pursuant to the exercise of Superior Options or (B)
         outstanding options, warrants, scrip, rights to subscribe for, calls or
         commitments of any character whatsoever relating to, or securities or
         rights convertible into or exchangeable for, shares of any class of
         capital stock of Superior, or contracts, understandings or arrangements
         to which Superior is a party, or by which it is or may be bound, to
         issue additional shares of its capital stock or options, warrants,
         scrip or rights to subscribe for, or securities or rights convertible
         into or exchangeable for, any additional shares of its capital stock.

                  (iii) Except as set forth in Section 2.2(b) of the Superior
         Disclosure Letter, all outstanding shares of capital stock of the
         Superior Subsidiaries (A) are owned by Superior or a wholly owned
         subsidiary of Superior, free and clear of all liens, charges,
         encumbrances, adverse claims and options of any nature, (B) were duly
         authorized and validly issued and are fully paid and nonassessable, and
         (C) have not been issued in violation of any preemptive rights. There
         are not now, and at the Effective Time there will not be, any
         outstanding options, warrants, scrip, rights to subscribe for, calls or
         commitments of any character whatsoever relating to, or securities or
         rights convertible into or exchangeable for, shares of any class of
         capital stock of the Superior Subsidiaries, or contracts,
         understandings or arrangements to which Superior or a Superior
         Subsidiary is a party, or by which any of them


                                      -12-
<PAGE>   17
         is or may be bound, to issue additional shares of its capital stock or
         options, warrants, scrip or rights to subscribe for, or securities or
         rights convertible into or exchangeable for, any additional shares of
         capital stock of any Superior Subsidiary. There are not now, and at the
         Effective Time there will not be, any outstanding contractual
         obligations of Superior or any of the Superior Subsidiaries to
         repurchase, redeem or otherwise acquire any outstanding shares of
         capital stock or other ownership interests of any such Superior
         Subsidiary or to provide funds to or make any investment (in the form
         of a loan, capital contribution or otherwise) in any such Superior
         Subsidiary or any other entity.

                  (iv)  Except for the Superior Subsidiaries or as set forth in
         Section 2.2(b) of the Superior Disclosure Letter, Superior does not,
         directly or indirectly, own of record or beneficially, or have the
         right or obligation to acquire, any outstanding securities or other
         interest in any corporation, partnership, joint venture or other
         entity.

              (c) Authorization and Validity of Agreement. Superior has all
         requisite corporate power and authority to enter into this Agreement
         and to perform its obligations hereunder. The execution and delivery by
         Superior of this Agreement and the consummation by it of the
         transactions contemplated hereby have been duly authorized by all
         necessary corporate action (subject only, with respect to the Merger,
         to approval of this Agreement by its stockholders as provided for in
         Section 5.1(a)). On or prior to the date hereof, the Board of Directors
         of Superior has determined to recommend approval of the Merger to the
         stockholders of Superior, and such determination is in effect as of the
         date hereof. This Agreement has been duly executed and delivered by
         Superior and is the valid and binding obligation of Superior,
         enforceable against Superior in accordance with its terms, except as
         the same may be limited by legal principles of general applicability
         governing the application and availability of equitable remedies.

              (d) No Approvals or Notices Required; No Conflict with Instruments
         to which Superior or any of the Superior Subsidiaries is a Party.
         Neither the execution and delivery of this Agreement nor the
         performance by Superior of its obligations hereunder, nor the
         consummation of the transactions contemplated hereby by Superior, will
         (i) conflict with the certificate of incorporation or bylaws of
         Superior or the charter or bylaws or other equivalent organizational
         documents of any of the Superior Subsidiaries; (ii) assuming
         satisfaction of the requirements set forth in clause (iii) below,
         violate any provision of law applicable to Superior or any of the
         Superior Subsidiaries; (iii) except for (A) requirements of federal or
         state securities laws, (B) requirements arising out of the HSR Act, (C)
         requirements of notice filings in such foreign jurisdictions as may be
         applicable, and (D) the filing of a certificate of merger in accordance
         with the DGCL, require any consent or approval of, or filing with or
         notice to, any public body or authority, domestic or foreign, under any
         provision of law applicable to Superior or any of the Superior
         Subsidiaries; or (iv) require any consent, approval or notice under, or
         violate, breach, be in conflict with or constitute a default (or an
         event that, with notice or lapse of time or both, would constitute a
         default) under, or permit the termination of any provision of, or
         result in the creation or imposition of any lien upon any properties,
         assets or business of Superior or any of the Superior Subsidiaries
         under, any note, bond, indenture, mortgage, deed of trust, lease,
         franchise, permit, authorization, license,


                                      -13-
<PAGE>   18
         contract, instrument or other agreement or commitment or any order,
         judgment or decree to which Superior or any of the Superior
         Subsidiaries is a party or by which Superior or any of the Superior
         Subsidiaries or any of their respective assets or properties is bound
         or encumbered, except (A) the approval by the stockholders of Superior
         of this Agreement in accordance with Section 5.1(a), (B) those that
         have already been given, obtained or filed, (C) those that are required
         pursuant to bank loan agreements, as set forth in Section 2.2(d) of the
         Superior Disclosure Letter, which Superior will use its reasonable
         efforts to obtain prior to the Effective Time, and (D) those that, in
         the aggregate, would not have a Superior MAE.

              (e) Commission Filings; Financial Statements. Superior and each of
         the Superior Subsidiaries have timely filed all reports, registration
         statements and other filings, together with any amendments required to
         be made with respect thereto, that they have been required to file with
         the Commission under the Securities Act and the Exchange Act. All
         reports, registration statements and other filings (including all
         notes, exhibits and schedules thereto and documents incorporated by
         reference therein) filed by Superior with the Commission since January
         1, 1996 through the date of this Agreement, together with any
         amendments thereto, are sometimes collectively referred to as the
         "Superior Commission Filings." As of the respective dates of their
         filing with the Commission, the Superior Commission Filings complied in
         all material respects with the Securities Act, the Exchange Act and the
         rules and regulations of the Commission thereunder, and did not contain
         any untrue statement of a material fact or omit to state a material
         fact required to be stated therein or necessary to make the statements
         made therein, in light of the circumstances under which they were made,
         not misleading.

              Each of the consolidated financial statements (including any
         related notes or schedules) included in the Superior Commission Filings
         was prepared in accordance with generally accepted accounting
         principles applied on a consistent basis (except as may be noted
         therein or in the notes or schedules thereto) and complied with the
         rules and regulations of the Commission. Such consolidated financial
         statements fairly present the consolidated financial position of
         Superior and the Superior Subsidiaries as of the dates thereof and the
         results of operations, cash flows and changes in stockholders' equity
         for the periods then ended (subject, in the case of the unaudited
         interim financial statements, to normal year-end audit adjustments on a
         basis consistent with past periods).

              (f) Absence of Undisclosed Liabilities. Except as disclosed in
         Section 2.2(f) of the Superior Disclosure Letter or in the Superior
         Commission Filings, as of the date of this Agreement, neither Superior
         nor any of the Superior Subsidiaries has any liabilities that are
         reasonably likely to have, individually or in the aggregate, a Superior
         MAE, except liabilities which are accrued or reserved against in the
         consolidated balance sheet of Superior as of December 31, 1997 or June
         30, 1998, included in the Superior Commission Filings or reflected in
         the notes thereto. Neither Superior nor any Superior Subsidiary has
         incurred or paid any liability since June 30, 1998, except for
         liabilities incurred or paid (i) in the ordinary course of business
         consistent with past practice, (ii) in connection with transactions


                                      -14-
<PAGE>   19
         contemplated by this Agreement, or (iii) pursuant to transactions not
         prohibited by this Agreement.

              (g) Conduct of Business in the Ordinary Course; Absence of Certain
         Changes and Events. Since January 1, 1998, except as contemplated by
         this Agreement or as disclosed in the Superior Commission Filings filed
         with the Commission prior to the date hereof or as set forth in Section
         2.2(g) of the Superior Disclosure Letter, Superior and the Superior
         Subsidiaries have conducted their business only in the ordinary and
         usual course, and there has not been (i) any Superior MAE, or any
         condition, event or development that reasonably may be expected to
         result in a Superior MAE; (ii) any material change by Superior in its
         accounting methods, principles or practices; (iii) any revaluation by
         Superior or any of the Superior Subsidiaries of any of their respective
         assets, including, without limitation, writing down the value of
         inventory or writing off notes or accounts receivable other than in the
         ordinary course of business; (iv) any entry by Superior or any of the
         Superior Subsidiaries into any commitment or transaction material to
         Superior and the Superior Subsidiaries, taken as a whole; (v) any
         declaration, setting aside or payment of any dividends or distributions
         in respect of Superior Common Stock or any redemption, purchase or
         other acquisition of any of its securities or any securities of any of
         the Superior Subsidiaries; (vi) any damage, destruction or loss
         (whether or not covered by insurance) materially adversely affecting
         the properties or business of Superior and the Superior Subsidiaries,
         taken as a whole; (vii) any increase in indebtedness for borrowed money
         other than an increase as a result of borrowings under existing credit
         facilities or indebtedness incurred in the ordinary course of business;
         (viii) any granting of a security interest in or lien on any material
         property or assets of Superior and the Superior Subsidiaries, taken as
         a whole, other than Permitted Liens; or (ix) any increase in or
         establishment of any bonus, insurance, severance, deferred
         compensation, pension, retirement, profit sharing, stock option
         (including, without limitation, the granting of stock options, stock
         appreciation rights, performance awards or restricted stock awards),
         stock purchase or other employee benefit plan or any other increase in
         the compensation payable or to become payable to any officers or key
         employees of Superior or any of the Superior Subsidiaries other than
         those that are required under existing contractual arrangements.

              (h) Litigation. Except as disclosed in the Superior Commission
         Filings or as set forth in Section 2.2(h) of the Superior Disclosure
         Letter, there are no claims, actions, suits, investigations, inquiries
         or proceedings (including any proceedings in arbitration) pending or,
         to the knowledge of Superior, threatened against or affecting Superior
         or any of the Superior Subsidiaries or any of their respective
         properties at law or in equity, or before or by any federal, state,
         municipal or other governmental agency or authority, or before any
         arbitration board or panel, wherever located, that individually or,
         with respect to multiple actions, suits or proceedings that allege
         similar theories of recovery based on similar facts, in the aggregate
         if adversely determined could have a Superior MAE, or that involve the
         risk of criminal liability. There are no claims pending or, to the
         knowledge of Superior, threatened by any present or former officer,
         director, employee or affiliate against Superior or any of the Superior
         Subsidiaries for indemnification pursuant to any statute,
         organizational


                                      -15-

         document, contract or otherwise with respect to any action, suit,
         investigation or proceeding pending in any court or before or by any
         governmental authority.

         corporation, trade, business or entity under common control with

         have been or on request will be furnished to Parker.

                  (ii)  None of Superior, any Superior Subsidiary or any

                  would result in the imposition on Superior, any Superior
                  Subsidiary or any Superior ERISA Affiliate of breach of
                  fiduciary duty liability damages under Section 409 of ERISA, a
                  civil penalty assessed pursuant to Subsections (c), (i) or (1)
                  of Section 502 of ERISA or a tax imposed pursuant to Chapter
                  43 of Subtitle D of the Code;

                        (D) the execution and delivery of this Agreement and the
                  consummation of the transactions contemplated hereby will not
                  require Superior, any Superior Subsidiary or any Superior
                  ERISA Affiliate to make a larger contribution to, or pay
                  greater benefits under, any Plan, Benefit Program or Agreement
                  than it otherwise would, whether or not some other subsequent
                  action or event would be required to cause such payment or
                  provision to be triggered, or create or give rise to any
                  additional vested rights or service credits under any Plan or
                  Benefit Program or Agreement; and

                        (E) each of the Plans intended to be qualified under
                  section 401 of the Code (1) satisfies in form the requirements
                  of such section except to the extent amendments are not
                  required by law to be made until a date after the Closing
                  Date, (2) has received a favorable determination letter from
                  the Internal Revenue Service regarding such qualified status,
                  (3) has not, since receipt of the most recent favorable
                  determination letter, been amended, and (4) has not been
                  operated in a way that would adversely affect its qualified
                  status.

                  (iv)  In connection with the consummation of the transactions
         contemplated by this Agreement, no payments of money or other property,
         acceleration of benefits, or provisions of other rights have or will be
         made hereunder, under any agreement contemplated hereby, or under the
         Plans or Benefit Programs or Agreements that would be reasonably likely
         to result in the imposition of the sanctions imposed under sections
         280G and 4999 of the Code, whether or not some other subsequent action
         or event would be required to cause such payment, acceleration or
         provision to be triggered.

                  (v)   Each Plan may be unilaterally amended or terminated in 
         its entirety without liability except as to benefits accrued thereunder
         prior to such amendment or termination.

              (j) Taxes. Except as set forth in Section 2.2(j) of the Superior
         Disclosure Letter, all federal and all material state, local, foreign
         returns, declarations, reports, including claims for refunds,
         estimates, information returns and statements (including any amendments
         thereof) ("Tax Returns") of or relating to any Taxes (as hereinafter
         defined) that are required to be filed on or before the Closing Date by
         or with respect to Superior or any of the Superior Subsidiaries, or any
         other corporation that is or was a member of an affiliated group
         (within the meaning of section 1504(a) of the Code) of corporations of
         which Superior was a member for any period ending on or prior to the
         Closing Date, have been or will be duly and timely filed with
         appropriate governmental authorities, and all Taxes, including interest
         and penalties, due and payable with respect to the periods covered by
         such Tax Returns or


                                      -17-
<PAGE>   22
         otherwise required to be duly paid or deposited by or with respect to
         Superior or any of the Superior Subsidiaries have been paid or
         adequately provided for in reserves established by Superior. Except as
         set forth in Section 2.2(j) of the Superior Disclosure Letter, all U.S.
         Federal Income Tax Returns of or with respect to Superior or any of the
         Superior Subsidiaries have been audited by the applicable governmental
         authority, or the applicable statute of limitations has expired, for
         all periods up to and including the tax year ended December 31, 1994.
         There is no material claim against Superior or any of the Superior
         Subsidiaries with respect to any Taxes, and no material assessment,
         deficiency or adjustment has been asserted or proposed with respect to
         any Tax Return of or with respect to Superior or any of the Superior
         Subsidiaries that has not been adequately provided for in reserves
         established by Superior in the consolidated financial statements
         included in the Superior Commission Filings. The total amounts set up
         as liabilities for current and deferred Taxes in the consolidated
         financial statements included in the Superior Commission Filings have
         been prepared in accordance with generally accepted accounting
         principles and are sufficient to cover the payment of all material
         Taxes, including any penalties or interest thereon and whether or not
         assessed or disputed, that are, or are hereafter found to be, or to
         have been, due with respect to the operations of Superior and the
         Superior Subsidiaries through the periods covered thereby. Superior and
         each of the Superior Subsidiaries have (and as of the Closing Date will
         have) made all deposits (including estimated tax payments for taxable
         years for which the consolidated federal income tax return is not yet
         due) required with respect to Taxes. Except as set forth in Section
         2.2(j) of the Superior Disclosure Letter, no waiver or extension of any
         statute of limitations as to any federal, local or foreign Tax matter
         has been given by or requested from Superior or any of the Superior
         Subsidiaries, and none of such Tax Returns are now under audit or
         examination by any federal, state, local or foreign or other
         governmental entity. Except for statutory liens for current Taxes not
         yet due, no liens for Taxes exist upon the assets of either Superior or
         the Superior Subsidiaries. Except as set forth in Section 2.2(j) of the
         Superior Disclosure Letter, neither Superior nor any of the Superior
         Subsidiaries (i) has filed consolidated income Tax Returns with any
         corporation, other than consolidated federal and state income Tax
         Returns with Superior, for any taxable period which is not now closed
         by the applicable statute of limitations, (ii) is a party to any tax
         sharing or tax indemnity agreement, or (iii) has any liability for
         Taxes of any other person (other than current members of Superior's
         affiliated group of corporations) under Treas. Reg. Section 1.1502-6 
         (or any similar provision of state, local or foreign law), as a
         transferee or successor, by contract or otherwise. Neither Superior nor
         the Superior Subsidiaries has any income or gain resulting from any
         intercompany transaction as described in Treas. Reg. Section 1.1502-13.

              Superior and the Superior Subsidiaries have made available to
         Parker true and correct copies of all federal, state and local income
         and franchise Tax Returns, examination reports and statements of
         deficiencies asserted or assessed against or agreed to by Superior or
         any Superior Subsidiary for all open Tax periods. None of the assets of
         Superior or the Superior Subsidiaries (i) is property that is required
         to be treated as being owned by any other person pursuant to the "safe
         harbor lease" provisions of former section 168(f)(8) of the Code, (ii)
         is "tax-exempt use property" within the meaning of section 168(h) of
         the Code, or (iii) secures any debt the interest on which is tax-exempt
         under section 103(a) of the Code.

         Superior Commission Filings or as set forth in Section 2.2(k) of the
         Superior Disclosure Letter and except for matters that in the aggregate
         would not have a Superior MAE, (i) the properties, operations and

         Environmental Law; (iii) all notices, permits, licenses or similar
         authorizations, if any, required to be obtained or filed by Superior or
         the Superior Subsidiaries under any Environmental Law in connection
         with any aspect of the business of Superior or the Superior
         Subsidiaries, including without limitation those relating to the
         treatment, storage, disposal or release of a hazardous substance or
         solid waste, have been duly obtained or filed and will remain valid and
         in effect after the Merger, and Superior and the Superior Subsidiaries
         are in compliance with the terms and conditions of all such notices,
         permits, licenses and similar authorizations; (iv) Superior and the
         Superior Subsidiaries have satisfied and are currently in compliance
         with all financial responsibility requirements applicable to their
         operations and imposed by the U.S. Coast Guard and Minerals Management
         Service pursuant to OPA (as hereinafter defined) or by any other
         governmental authority under any other Environmental Law, and Superior
         and the Superior Subsidiaries have not received any notice of
         noncompliance with any such financial responsibility requirements; (v)
         to the knowledge of Superior, there are no physical or environmental
         conditions existing on any property of Superior and the Superior
         Subsidiaries or resulting from Superior's and the Superior
         Subsidiaries' operations or activities, past or present, at any
         location, that would give rise to any on-site or off-site remedial
         obligations under any Environmental Laws; (vi) to the knowledge of
         Superior, since the effective date of the relevant requirements of
         applicable Environmental Laws, all hazardous substances or solid wastes
         generated by Superior or any of the Superior Subsidiaries or used in
         connection with any of their properties or operations have been
         transported only by carriers authorized under Environmental Laws to
         transport such substances and wastes, and disposed of only at
         treatment, storage and disposal facilities authorized under
         Environmental Laws to treat, store or dispose of such substances and
         wastes, and, to the knowledge of Superior, such carriers and facilities
         have been and are operating in compliance with such authorizations and
         are not the subject of any existing, pending or overtly threatened
         action, investigation or inquiry by any governmental authority


                                      -19-
<PAGE>   24
         in connection with any Environmental Laws; (vii) there has been no
         exposure of any person or property to hazardous substances, solid
         waste, or any pollutant or contaminant, nor has there been any release
         of hazardous substances, solid waste, or any pollutant or contaminant
         into the environment by Superior or the Superior Subsidiaries or in
         connection with any of their properties or operations that could
         reasonably be expected to give rise to any claim for damages or
         compensation; and (viii) Superior and the Superior Subsidiaries have
         made available to Parker true and correct copies of all internal and
         external environmental audits and studies and all correspondence on

         Superior Subsidiaries relating to any of the current or former
         properties or operations of Superior and the Superior Subsidiaries.

              For purposes of this Agreement, the term "Environmental Laws"
         shall mean any and all laws, statutes, ordinances, rules, regulations,
         orders or determinations of any Governmental Authority pertaining to
         health or the environment currently in effect in any and all
         jurisdictions in which the party in question and its subsidiaries own
         property or conduct business, including, without limitation, the Clean
         Air Act, as amended, the Comprehensive Environmental, Response,
         Compensation, and Liability Act of 1980 ("CERCLA"), as amended, the
         Federal Water Pollution Control Act, as amended, the Occupational
         Safety and Health Act of 1970, as amended, the Resource Conservation
         and Recovery Act of 1976 ("RCRA"), as amended, the Safe Drinking Water
         Act, as amended, the Toxic Substances Control Act, as amended, the
         Hazardous & Solid Waste Amendments Act of 1984, as amended, the

         terms "hazardous substance" and "release" have the meanings specified
         in CERCLA, and the terms "solid waste" and "disposal" have the meanings
         specified in RCRA; provided, however, that to the extent the laws of
         the state in which the property is located establish a meaning for
         "hazardous substance," "release," "solid waste" or "disposal" that is
         broader than that specified in either CERCLA or RCRA, such broader
         meaning shall apply. For purposes of this Agreement, the term

         city and political subdivisions in which the party in question owns

         Merger or the transactions contemplated by this Agreement, nor will any
         of such persons be entitled to severance payments or other benefits as
         a result of the Merger or the transactions contemplated by this
         Agreement in the event of the subsequent termination of their
         employment.

              (m) Voting Requirements. The affirmative vote of the holders of a
         majority of the outstanding shares of Superior Common Stock is the only

         2.2(n) of the Superior Disclosure Letter, the disallowance of a
         deduction under section 162(m) of the Code for employee remuneration
         will not apply to any amount paid or payable by Superior or the
         Surviving Corporation or any of their subsidiaries under any contract,
         benefit plan, program, arrangement or understanding of Superior
         currently in effect.

              (o) Brokers. No agent, broker, person or firm acting on behalf of
         Superior is or will be entitled to any commission or broker's or
         finder's fee from any of the parties hereto in connection with any of
         the transactions contemplated herein, except fees to Johnson Rice &
         Company L.L.C. to be paid by Superior.

              (p) Labor Relations. Except as set forth in Section 2.2(p) of the
         Superior Disclosure Letter, neither Superior nor any of the Superior
         Subsidiaries is a party to, or bound by, any collective bargaining
         agreement, contract or other agreement or understanding with respect to
         a labor union or labor organization, and, to the knowledge of Superior,
         there are no organizational efforts with respect to the formation of a
         collective bargaining unit presently being made or threatened involving
         employees of Superior or any of the Superior Subsidiaries. There are no
         unfair labor practice complaints against Superior or any of the
         Superior Subsidiaries pending before the National Labor Relations Board
         and there is no labor strike, dispute, slow down or stoppage, or any
         union organizing campaign, actually pending or, to the knowledge of
         Superior, threatened against Superior or any of the Superior
         Subsidiaries, except for any such proceedings which would not
         reasonably be expected to have a Superior MAE.

              (q) Insurance. Section 2.2(q) of the Superior Disclosure Letter
         sets forth a list and brief description of the insurance policies of
         Superior and the Superior Subsidiaries relating to their properties and
         the conduct of their business. All premiums due and arising thereon
         have been paid and such policies are in full force and effect. True and
         correct copies of all such insurance policies have been or on request
         will be made available to Parker.

              (r) Title to Properties. Superior or the Superior Subsidiaries,
         individually or together, have good and marketable title to all of the
         properties reflected in Superior's consolidated balance sheet as of
         June 30, 1998 (the "Consolidated Balance Sheet"), other than any
         properties reflected in Superior's Consolidated Balance Sheet that (i)
         have been sold or otherwise disposed of since the date of Superior's
         Consolidated Balance Sheet in the ordinary course of business
         consistent with past practice or (ii) are not, individually or in the
         aggregate, material to Superior, free and clear of security interests
         or liens, other than (y) liens the existence of which is reflected in
         Superior's Consolidated Financial Statements, and (z) Permitted Liens.
         Superior or the Superior Subsidiaries, individually or together, hold
         under valid lease agreements all real and personal properties reflected
         in Superior's Consolidated Balance Sheet as being held under
         capitalized leases, and all real and personal


                                      -21-

         property that is subject to operating leases, and enjoy peaceful and
         undisturbed possession of such properties under such leases, other than
         (i) any properties as to which such leases have expired in accordance
         with their terms without any liability of any party thereto since the
         date of Superior's Consolidated Balance Sheet and (ii) any properties
         that, individually or in the aggregate, are not material to Superior.
         Neither Superior nor any Superior Subsidiary has received any written
         notice of any adverse claim to the title to any properties owned by
         them or with respect to any lease under which any properties are held
         by them, other than any claims that, individually or in the aggregate,
         could not reasonably be expected to have a Superior MAE.

              (s) Permits; Compliance. Superior and the Superior Subsidiaries
         have obtained all permits, licenses, authorizations, orders,
         certificates, registrations or other approvals (collectively,
         "Permits") that are necessary to carry on their businesses as currently
         conducted, except for any such Permits as to which, individually or in
         the aggregate, the failure to possess could not reasonably be expected
         to have a Superior MAE. Such Permits are in full force and effect, have
         not been violated in any respect that could reasonably be expected to
         have a Superior MAE and no suspension, revocation or cancellation
         thereof has been threatened, and there is no action, proceeding or
         investigation pending or threatened regarding suspension, revocation or
         cancellation of any of such Permits, except where the suspension,
         revocation or cancellation of such Permits could not reasonably be
         expected to have a Superior MAE.

              (t) Contingent Payment Obligations. Set forth in Section 2.2(t) of
         the Superior Disclosure Letter is a listing of all contingent amounts
         required by Superior or any Superior Subsidiary to be paid after the
         Effective Time relating to acquisitions by Superior or any Superior
         Subsidiary completed prior to the Effective Time.

              (u) Certain Business Practices. As of the date of this Agreement,
         neither Superior or any of the Superior Subsidiaries nor any director,
         officer, employee or agent of Superior or any of the Superior
         Subsidiaries has (i) used any funds for unlawful contributions, gifts,
         entertainment or other unlawful payments relating to political
         activity, (ii) made any unlawful payment to any foreign or domestic
         government official or employee or to any foreign or domestic political
         party or campaign or violated any provision of the FCPA, (iii)
         consummated any transaction, made any payment, entered into any
         agreement or arrangement or taken any other action in violation of
         Section 1128B(b) of the SSA, or (iv) made any other unlawful payment.

              (v) Opinion of Financial Advisor. Superior has received the
         opinion of Johnson Rice & Company on the date of this Agreement to the
         effect that the Merger Consideration is fair, from a financial point of
         view, to the holders of Superior Common Stock.

              (h) Superior shall not, and shall not permit any of the Superior
         Subsidiaries to, take any action that would, or that reasonably could

Superior Subsidiaries, or the acquisition, directly or indirectly, of a material
interest in any voting securities of Superior or any of the Superior

Board of Directors of Superior from (i) furnishing information to (but only

Confidentiality Agreement between Superior and Parker dated October 22, 1998
(the "Confidentiality Agreement")) or entering into discussions or negotiations
with any person or group that makes an unsolicited bona fide written proposal
for a Superior Acquisition Transaction (an "Alternative Proposal"), if, and only
to the extent that, (A) the Board of Directors of Superior, based on the written
opinion of outside counsel (a copy of which shall be provided promptly to
Parker), determines in good faith that such action is required for the Board of
Directors of Superior to comply with its fiduciary duties to stockholders
imposed by law, (B) such Alternative Proposal is not conditioned on the receipt
of financing, the Board of Directors of Superior has reasonably concluded in
good faith that the person or group making such Alternative Proposal will have
adequate sources of financing to consummate such Alternative Proposal and that
such Alternative Proposal is more favorable to the stockholders of Superior than
the Merger, and the Board of Directors of Superior has received a written
opinion from a nationally-recognized investment banking firm (a copy of which
shall be provided promptly to Parker) to the effect that the consideration to be
received by stockholders of Superior in connection with such Alternative
Proposal is superior, from a financial point of view, to the consideration to be


                                      -25-

received by them in the Merger, (C) prior to furnishing such information to, or

deliver or cause to be delivered to Parker on or prior to the Closing Date a
duly executed affiliate letter in the form of Exhibit A (an "Affiliate's
Agreement") for each such "affiliate" of Superior. Parker shall be entitled to

evidencing any Parker Common Stock to be received by such affiliates pursuant to

Effective Time, those employees of Superior and the Superior Subsidiaries who
become employees of the Surviving Corporation or a subsidiary of the Surviving
Corporation or Parker or a Parker Subsidiary shall be entitled to participate in
all employee benefit plans of Parker, including, without limitation, the Parker
401(k) savings plan, in respect of their service after the Effective Time to the
same extent that employees of Parker who are employed in comparable positions
are entitled to participate. Parker and Superior further agree that any such
employees shall be credited for their service with Superior for purposes of
eligibility, benefit entitlement and vesting in the plans provided by Parker.
Such employees' benefits under Parker's medical benefit plan shall not be
subject to any exclusions for any pre-existing conditions (to the extent such
exclusions did not apply under Superior's medical benefit plan), and credit
shall be received for any deductibles or out-of-pocket amounts previously paid.
The employees of Superior and the Superior Subsidiaries shall continue to
participate in the benefit plans of Superior to the extent that the requirements
set forth in the first sentence of this Section 5.6 are not satisfied.

         5.7  SUPERIOR STOCK OPTIONS.

              (a) Superior shall, in accordance with the terms of the Superior
Stock Option Plan, cause each Superior Option that is outstanding under such
plan at the Effective Time that has an exercise price in excess of the market
price of the Superior Common Stock on the Closing Date (each an
"Out-of-the-Money Superior Option") to be canceled as of the Effective Time. At
the Effective Time, (i) Parker shall assume the Superior Stock Option Plan and
(ii) each Superior Option that is outstanding under the Superior Stock Option
Plan as of the Effective Time (other than the Out-of-the-Money Superior Options)
shall fully vest in accordance with the terms of the Superior Stock Option Plan
and shall be deemed to constitute an option to acquire, on the same terms and
conditions as were applicable under the Superior Stock Option Plan and such
Superior Option, 0.90 of a share of Parker Common Stock for each share of
Superior Common Stock covered by such Superior Option (rounded downward to the
nearest whole number), at a price per share (rounded upward to the nearest whole
cent) equal to (y) the aggregate exercise price per share of Superior Common
Stock purchasable pursuant to such Superior Option immediately prior to the
Effective Time divided by (z) 0.90.

              (b) As soon as practicable after the Effective Time, Parker shall
deliver to the participants in the Superior Stock Option Plan appropriate notice
setting forth such participants' rights pursuant thereto and, except as
otherwise provided in subsection (a) above, the grants pursuant to the Superior
Stock Option Plan shall continue in effect on the same terms and conditions
(subject to the adjustments required by this Section 5.7 after giving effect to
the Merger).

              (c) At the Effective Time, Parker shall grant to each holder of an
Out-of-the-Money Superior Option who is employed by Superior at such time an
option (each a "Replacement Option") to purchase a number of shares of Parker
Common Stock equal to the number of shares of Superior Common Stock covered by
such Out-of-the-Money Superior Option at the time it was canceled multiplied by
0.90. Each Replacement Option shall be granted pursuant to a stock option plan
maintained by Parker or the Superior Stock Option Plan, as determined by Parker
in its sole discretion. The purchase price for each share of Parker Common Stock
subject to each Replacement Option shall be equal to the closing sales price of
the Parker Common Stock on the Closing Date (or, if there are no sales on that
date, the last preceding date on which there was a sale) on the New York Stock
Exchange (the "Market Value per Share"). Subject to the terms of the stock
option plan pursuant to which a Replacement Option is granted and the agreement
to be executed by Parker and each such individual evidencing the grant of such
option (which agreement shall be in the form customarily used for granting
options under such plan), each such option shall (i) have a term of ten years
(which term shall begin on the Closing Date), (ii) vest and become exercisable
in accordance with the vesting schedules set forth in the corresponding
Out-of-the-Money Superior Options, and (iii) constitute an option that is not
intended to be treated as an incentive stock option (within the meaning of
section 422 of the Code).

              (d) At the Effective Time, Parker shall grant to each of the
persons listed on Annex II (provided such individual is employed by Superior at
such time) an option to purchase 75,000 shares of Parker Common Stock pursuant
to a stock option plan maintained by Parker or the Superior Stock Option Plan,
as determined by Parker in its sole discretion. The purchase price for


                                      -32-
<PAGE>   37
each share of Parker Common Stock subject to each such option shall be equal to
the Market Value per Share. Subject to the terms of the stock option plan
pursuant to which such options are granted and the agreement to be executed by
Parker and each such individual evidencing the grant of such option (which
agreement shall be in the form customarily used for granting options under such
plan), each such option shall (i) have a term of ten years (which term shall
begin on the Closing Date), (ii) vest and become exercisable with respect to (A)
20% of the shares covered thereby on the Closing Date and (B) an additional 20%
of the shares covered thereby on each of the first, second, third and fourth
anniversaries of the Closing Date, and (iii) constitute an option that is not
intended to be treated as an incentive stock option (within the meaning of
section 422 of the Code).

              (e) As soon as practicable after the Effective Time, Parker shall
file a registration statement on Form S-8 (or any successor or other appropriate
forms), or another appropriate form with respect to the shares of Parker Common
Stock subject to the options described in the preceding paragraphs of this
Section 5.7 and shall use its reasonable efforts to maintain the effectiveness
of such registration statement or registration statements (and maintain the
current status of the prospectus or prospectuses contained therein), for so long
as such options remain outstanding.

              (f) The Board of Directors of Superior (or a duly appointed
committee thereof responsible for the administration of the Superior Stock
Option Plan in accordance with the terms of such plan) shall, prior to or as of
the Effective Time, take all necessary actions, pursuant to and in accordance
with the terms of the Superior Stock Option Plan and the instruments evidencing
the Superior Options, to provide (i) for the cancellation of the
Out-of-the-Money Superior Options as provided in paragraph (a) of this Section
5.7, (ii) for the conversion of the Superior Options (other than the
Out-of-the-Money Superior Options) into options to acquire Parker Common Stock
in accordance with paragraph (a) of this Section 5.7, and (iii) that no consent
of the holders of the Superior Options is required in connection with such
cancellation and conversion.

         5.8  [Intentionally omitted]

         5.9  TAX-FREE REORGANIZATION.

              (a) Parker and Superior shall each use its best efforts to cause
the Merger to be treated as a reorganization within the meaning of section
368(a) of the Code.

              (b) To the extent permitted under applicable tax laws, the Merger
shall be reported as a reorganization within the meaning of sections
368(a)(1)(A) and 368(a)(2)(E) of the Code in all federal, state, and local Tax
Returns after the Effective Time.

              (c) Following the Merger, the Surviving Corporation will hold at
least 90 percent of the fair market value of Superior's net assets, at least 70
percent of the fair market value of Superior's gross assets, at least 90 percent
of the fair market value of the net assets of Sub and at least 70 percent of the
fair market value of the gross assets of Sub, held immediately prior to the
Merger, taking into account amounts used to pay reorganization expenses and any
distributions other than regular dividends.

         5.10 INDEMNIFICATION.

              (a) From and after the Effective Time, Parker and the Surviving
Corporation shall, to the extent provided in the certificate of incorporation or
by-laws of Superior immediately prior to the Effective Time, indemnify, defend
and hold harmless each person who is now, or has been at any time prior to the
date hereof or who becomes prior to the Effective Time, an officer, director or
employee of Superior or any of the Superior Subsidiaries (the "Indemnified
Parties") against losses, claims, damages, costs, expenses, liabilities or
judgments or amounts that are paid in settlement with the approval of the
indemnifying party (which approval shall not be unreasonably withheld) of or in
connection with a claim, action, suit, proceeding or investigation based in
whole or in part on or arising in whole or in part out of the fact that such
person is or was a director, officer or employee of Superior or any of the
Superior Subsidiaries, whether pertaining to any matter existing or occurring at
or prior to the Effective Time and whether reasserted or claimed prior to, or at
or after, the Effective Time. The defense of any such claim, action, suit,
proceeding or investigation shall be conducted by Parker and the Surviving
Corporation. If Parker or the Surviving Corporation has failed to conduct such
defense, the Indemnified Parties may retain counsel satisfactory to them and
Parker and the Surviving Corporation shall pay all reasonable fees and expenses
of such counsel for the Indemnified Parties promptly as statements therefor are
received. The party not conducting the defense will use reasonable efforts to
assist in the vigorous defense of any such matter, provided that such party
shall not be liable for any settlement of any claim effected without its written
consent, which consent, however, shall not be unreasonably withheld. Any
Indemnified Party wishing to claim indemnification under this Section 5.10, upon
learning of any such claim, action, suit, proceeding or investigation, shall
notify Parker and the Surviving Corporation (but the failure so to notify shall
not relieve them from any liability which they may have under this Section 5.10
except to the extent such failure prejudices them). If Parker and the Surviving
Corporation are responsible for the attorneys' fees of the Indemnified Parties,
then the Indemnified Parties as a group may retain only one law firm to
represent them with respect to each such matter unless there is, under
applicable standards of professional conduct, a conflict on any significant
issue between the positions of any two or more Indemnified Parties.

              (b) The Surviving Corporation shall purchase and maintain for a
period of four years after the Effective Time continuation coverage for
Superior's directors' and officers' liability insurance policy as in effect on
the date hereof or obtain a directors' and officers' insurance policy with
comparable coverage; provided, however, that the Surviving Corporation shall not
be required to expend in any year an amount in excess of 150% of the annual
aggregate premiums currently paid by Superior for such insurance; and provided,
further, that if the annual premiums of such insurance coverage exceed such
amount, the Surviving Corporation shall be obligated to obtain a policy with the
best coverage available, in the reasonable judgment of the Board of Directors of
Parker, for a cost not exceeding such amount.

              (c) The rights granted hereunder to the Indemnified Parties who
are Superior directors shall be contractual rights inuring to the benefit of
such Indemnified Parties and shall survive this Agreement and any merger,
consolidation or reorganization of the Surviving Corporation or Parker.

         consummation of the Merger, shall have been obtained; save and except

         warranties had been made at and as of that time; all of the terms,
         covenants and conditions of this Agreement to be complied with and

         7.3  WAIVER AND AMENDMENT. Any provision of this Agreement may be 
waived at any time by the party that is, or whose stockholders are, entitled to
the benefits thereof. This Agreement may not be amended or supplemented at any
time, except by an instrument in writing signed on behalf of each party hereto,
provided that after this Agreement has been approved and adopted by the
stockholders of Superior or the Share Issuance and Charter Amendment have been
approved by stockholders of Parker, this Agreement may be amended only as may be
permitted by applicable provisions of the DGCL. The waiver by any party hereto
of any condition or of a breach of another provision of this Agreement shall not
operate or be construed as a waiver of any other condition or subsequent breach.
The waiver by any party hereto of any of the conditions precedent to its
obligations under this Agreement shall not preclude it from seeking redress for
breach of this Agreement other than with respect to the condition so waived.

         7.4  FEES, EXPENSES AND OTHER PAYMENTS.

              (a) Except as provided in this Section 7.4, all costs and expenses
incurred in connection with this Agreement and the transactions contemplated
hereby shall be paid by the parties incurring such expense, except that expenses
incurred in connection with printing and mailing the Registration Statement and
the Joint Proxy Statement/Prospectus shall be shared equally by Parker and
Superior. 

              (b) If this Agreement is terminated by Parker pursuant to Section
7.1(h) or by Superior pursuant to Section 7.1(i), then Superior shall pay to
Parker a termination fee equal to $7 million.

<PAGE>   44
              (c) If this Agreement is terminated by Parker or Superior pursuant
to Sections 7.1(d) or 7.1(f) and within 12 months of any such termination,
Superior or any of the Superior Subsidiaries accepts a written offer or enters
into a written agreement to consummate a Superior Acquisition Proposal with such
person or any of its Affiliates and Superior or such Superior Subsidiary is
acquired, through merger, consolidation, share exchange, sale of assets or
otherwise, by such person or any of its Affiliates, then Superior shall at the
closing (and as a condition of such closing) pay to Parker immediately a
termination fee of $7 million.

              (d) If Superior shall fail to pay Parker any fee or other amount
due hereunder, Superior shall pay the costs and expenses (including legal fees
and expenses) of Parker in connection with any action, including the filing of
any lawsuit or other legal action, taken to collect payment, together with
interest on the amount of any unpaid fee at the publicly announced prime
interest rate of Citibank N.A. in effect from time to time, from the date such
fee or other payment was required to be paid until payment in full.

              (e) Subject to the following sentences, the payments required by
this Section 7.4 shall constitute liquidated damages in full and complete
satisfaction of, and shall be the sole and exclusive remedy of Parker for, any
loss, liability, damage or claim arising out of or in conjunction with the
transactions contemplated by this Agreement, including any termination of this
Agreement pursuant to Section 7.1 and shall not constitute a penalty.
Notwithstanding the foregoing sentence, if (i) this Agreement is terminated by
Parker as a result of an intentional breach of any representation, warranty,
covenant or agreement by Superior and no termination fee is required to be paid
pursuant to Section 7.4(c), Parker may pursue any remedies available to it at
law or in equity and shall be entitled to recover such additional amounts as
Parker may be entitled to receive at law or in equity or (ii) this Agreement is
terminated by Superior as a result of an intentional breach of any
representation, warranty, covenant or agreement by Parker, Superior may pursue
any remedies available to it at law or in equity and shall be entitled to
recover such additional amounts as Parker may be entitled to receive at law or
in equity.

of law thereof; provided, however, that any matter involving the internal
corporate affairs of any party hereto shall be governed by the provisions of the

         8.6  SEVERABILITY. If any term, provision, covenant or restriction of

that the failure of any party to this Agreement to perform its agreements and

                              AFFILIATE'S AGREEMENT

                                     [Date]


[Parker Address]

Ladies and Gentlemen:

         The undersigned has been advised that, as of the date hereof, the
undersigned may be deemed to be an "affiliate" of Superior Energy Services,
Inc., a Delaware corporation ("Superior"), as that term is defined for purposes
of paragraphs (c) and (d) of Rule 145 of the Regulations of the Commission under
the Securities Act (an "Affiliate").

         Pursuant to the terms and subject to the conditions of that certain
Agreement and Plan of Merger by and among Parker Drilling Company, a Delaware
corporation ("Parker"), Saints Acquisition Company., a newly formed Delaware
corporation and a wholly-owned Subsidiary of Parker ("Sub"), and Superior dated
as of October 28, 1998 (the "Merger Agreement"), providing for, among other
things, the merger of Sub with and into Superior (the "Merger"), the undersigned
will be entitled to receive shares of Parker Common Stock in exchange for shares
of Superior Common Stock owned by the undersigned at the Effective Time of the
Merger as determined pursuant to the Merger Agreement. Capitalized terms used
but not defined herein are defined in the Merger Agreement and are used herein
with the same meanings as ascribed to them therein.

         The undersigned understands that the Merger will be treated for
financial accounting purposes as a "pooling of interests" in accordance with
generally accepted accounting principles and that the staff of the Commission
has issued certain guidelines that should be followed to ensure the application
of pooling of interests accounting to the transaction.

         In consideration of the agreements contained herein, Parker's reliance
on this letter in connection with the consummation of the Merger and for other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the undersigned hereby represents, warrants and agrees that the
undersigned will not make any sale, transfer or other disposition of (i)
Superior Common Stock during the period from the date hereof until the earlier
of the Effective Time and the termination of the Merger Agreement (which period,
if the Merger is consummated, will be greater than thirty (30) days), (ii)
Parker Common Stock received by the undersigned pursuant to the Merger or
otherwise owned by the undersigned until such time as financial statements that
include at least thirty (30) days of combined operations of Superior and Parker
after the Merger shall have been publicly reported, unless the undersigned shall
have delivered to Parker, prior to any such sale, transfer or other disposition,
a written opinion from PricewaterhouseCoopers LLP, independent public
accountants for Parker, or a written no-action letter from the accounting staff
of the Commission, in either case in form and substance reasonably satisfactory
to Parker, to the effect that such sale, transfer or other disposition will not
cause the Merger not to be treated as
<PAGE>   52
a "pooling of interests" for financial accounting purposes in accordance with
generally accepted accounting principles and the Regulations of the Commission
or (iii) Parker Common Stock received by the undersigned pursuant to the Merger
in violation of the Securities Act or the Regulations thereunder. The
undersigned has been advised that the offering, sale and delivery of the shares
of Parker Common Stock pursuant to the Merger will have been registered with the
Commission under the Securities Act on a Registration Statement on Form S-4. The
undersigned has also been advised, however, that, since the undersigned may be
deemed to be an Affiliate at the time the Merger is submitted for a vote of the
stockholders of Superior, Parker Common Stock received by the undersigned
pursuant to the Merger can be sold by the undersigned only (i) pursuant to an
effective registration statement under the Securities Act, (ii) in conformity
with the volume and other limitations of Rule 145 promulgated by the Commission
under the Securities Act or (iii) in reliance upon an exemption from
registration that is available under the Securities Act.

         The undersigned also understands that instructions will be given to the
Exchange Agent for Parker Common Stock with respect to Parker Common Stock to be
received by the undersigned pursuant to the Merger and that there will be placed
on the certificates representing such shares of Parker Common Stock, or any
substitutions therefor, a legend stating in substance as follows:

         "These shares were issued in a transaction to which Rule 145
         promulgated under the Securities Act of 1933, as amended, applies.
         These shares may only be transferred in accordance with the terms of
         such Rule and an Affiliate's Agreement between the original holder of
         such shares and Parker Corporation, a copy of which agreement is on
         file at the principal offices of Parker Corporation."

It is understood and agreed that the legend set forth above shall be removed
upon surrender of certificates bearing such legend by delivery of substitute
certificates without such legend if the undersigned shall have delivered to
Parker an opinion of counsel, in form and substance reasonably satisfactory to
Parker, to the effect that (i) the sale or disposition of the shares represented
by the surrendered certificates may be effected without registration of the
offering, sale and delivery of such shares under the Securities Act and (ii) the
shares to be so transferred may be publicly offered, sold and delivered by the
transferee thereof without compliance with the registration provisions of the
Securities Act.

         By its execution hereof, Parker agrees that it will, as long as the
undersigned owns any Parker Common Stock to be received by the undersigned
pursuant to the Merger, take all reasonable efforts to make timely filings with
the Commission of all reports required to be filed by it pursuant to the
Exchange Act and will promptly furnish upon written request of the undersigned a
written statement confirming that such reports have been so timely filed.

                          FORM OF JONES, WALKER OPINION


                                October __, 1998



Superior Energy Services, Inc.
1105 Peters Road
Harvey, Louisiana  70058

Ladies and Gentlemen:

         We have acted as counsel to Superior Energy Services, Inc., a Delaware
corporation ("Superior"), in connection with the Merger (the "Merger") and
related transactions contemplated by that certain Agreement and Plan of Merger
dated October 28, 1998, by and among Parker Drilling Company, a Delaware
corporation ("Parker"), Saints Acquisition Company, a Delaware corporation and a
wholly owned subsidiary of Parker ("Merger Sub"), and Superior (the
"Agreement"), pursuant to which Merger Sub will be merged with and into
Superior. Capitalized terms used herein but not defined herein shall have the
meaning ascribed to them in the Agreement. This opinion is being rendered
pursuant to Section 6.2(d) of the Agreement.

         In connection therewith, we have examined copies of the Agreement and
originals, or photostatic or certified copies, of such corporate records of
Superior, and such communications, certificates of public officials,
certificates of officers of Superior and other documents, as we have deemed
necessary or appropriate for the purposes of this opinion. As to matters of fact
relevant to the opinions expressed herein and as to factual matters arising in
connection with our examination of the corporate documents, records and
instruments of Superior, and other documents or writings, we have relied, to the
extent we deem necessary or appropriate, upon the representations and warranties
made by Superior in the Agreement and related instruments, and upon certificates
and other communications of corporate officers of Superior, without further
investigation as to the facts set forth therein. We have assumed the genuineness
of all signatures, the authenticity of all documents submitted to us as
originals, and the conformity to original documents of all documents submitted
to us as certified or photostatic copies.

         Based upon the foregoing, and in reliance thereon, and subject to the
assumptions, qualifications and limitations hereinafter set forth, we are of the
opinion that:

         1. Superior is a corporation duly incorporated, validly existing and in
good standing under the laws of the State of Delaware and has all requisite
corporate power and authority to carry on its business as now being conducted as
described in the Registration Statement on Form S-4 (Registration No.
__________) filed with the Securities and Exchange Commission by Parker pursuant
to the Securities Act of 1933, as amended, which became effective on
_____________;

<PAGE>   55
         2. The appropriate filings have been made with respect to the Merger
with the Secretary of State of the State of Delaware to cause the Merger to
become effective;

         3. Superior has the requisite corporate power to merge with Merger Sub
as contemplated by the Agreement;

         4. The execution and delivery of the Agreement did not, and the
consummation of the Merger will not, violate any provisions of Superior'
Articles of Incorporation or Bylaws, each as amended to date; and

         5. The Agreement has been duly and validly authorized, executed and
delivered by Superior, and the Agreement is a valid and binding agreement of
Superior enforceable in accordance with its terms, except as such enforceability
may be limited by bankruptcy, insolvency, reorganization, moratorium or other
similar laws or court decisions affecting creditors' rights generally and by
other general equitable principles and except as the enforceability of the
indemnification provision may be limited by applicable federal or state
securities laws.

         This opinion is limited to the laws of the State of Delaware and the
federal laws of the United States of America and the General Corporation Law of
the State of Delaware.

         This opinion is solely for your benefit and except for Parker, which
shall be entitled to rely on this opinion, may not be relied upon by any other
person without our written permission.


                                       Very truly yours,

Ladies and Gentlemen:

         We have acted as counsel to Parker Drilling Company, a Delaware

         In connection with rendering the opinions hereinafter set forth, we
have examined originals or photostatic or certified copies of all such corporate
records of Parker and its subsidiaries, such agreements, communications and
other instruments, certificates of officers of Parker, certificates and
telegrams of public officials, and such other documents as we have deemed
relevant and necessary as the basis for the opinions hereinafter expressed. In
such examination, we have assumed the genuineness of all signatures and the
authenticity of all documents submitted to us as originals, the correctness of
all statements of fact contained therein, the conformity to original documents
of all documents submitted to us as certified or photostatic copies and the due

certain questions of fact material to the opinions hereinafter set forth, we
have, to the extent we deemed appropriate, relied on certificates of officers of
Parker and on certificates and telegrams of governmental officials.

         Based upon the foregoing, and having regard for such legal
considerations as we deem relevant, we are of the opinion that:

         1. Parker is a corporation duly incorporated, validly existing and in
good standing under the laws of the State of Delaware and has all requisite
corporate power and authority to carry on its

         4. Merger Sub has the requisite corporate power to merge with and into
Superior as contemplated by the Agreement.

         5. The execution and delivery of the Agreement did not, and the
consummation of the Merger will not, violate any provision of Parker's Restated
Certificate of Incorporation or Bylaws or Merger Sub's Certificate of
Incorporation or Bylaws.

         6. The Agreement has been duly and validly authorized, executed and
delivered by Parker and Merger Sub, and the Agreement is a valid and binding
agreement of Parker and Merger Sub enforceable in accordance with its terms,
except as such enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws or court decisions affecting
creditors' rights generally and by other general equitable principles and except
as the enforceability of the indemnification provision may be limited by
applicable federal or state securities laws.

         7. The Registration Statement has become effective under the Securities
Act.

         8. The shares of Parker Common Stock to be delivered in connection with
the Merger are duly authorized and reserved for issuance and, when issued in
accordance with the terms and conditions of the Agreement, will be validly
issued, fully paid and nonassessable.

         The opinions set forth herein are specifically limited to matters of
the laws of the State of Delaware and of the United States, and the General
Corporation Law of the State of Delaware.

         This letter is furnished to you solely for your benefit pursuant to the

PARKER DRILLING AND SUPERIOR ENERGY SERVICES
ANNOUNCE PLANNED MERGER

(Tulsa, Oct. 29, 1998) -- Parker Drilling Company (NYSE: PKD) and Superior
Energy Services, Inc. (NASDAQ: SESI) jointly announced today the execution of a
definitive agreement to combine the two companies.

         Under the terms of the agreement, each share of Superior common stock
will be exchanged for 0.9 shares of Parker. With the exchange of shares and
assumed debt of $25 million, the total current market value of the transaction
is approximately $168 million. The deal is expected to close in early 1999 and
is subject to approval of Parker and Superior shareholders and the customary
regulatory approvals.

         As a result of the transaction, Parker will issue approximately 26
million new shares to current Superior shareholders, and will then have
approximately 103 million shares outstanding after the closing of the
transaction.

         "Our merger with Superior Energy Services continues our long term
corporate strategy to expand this high-margin side of our business," said Robert
L. Parker Jr., Parker Drilling's president and chief executive officer.
"Superior's wide geographic presence and excellent reputation with Gulf of
Mexico operators will allow Parker to expand our premium rental tool business
in deep offshore markets and internationally."

         "Obviously, this transaction rewards our shareholders with a
substantial premium," said Terence Hall, Superior's chairman, president and
chief executive officer. "But more importantly, it will allow our existing
business lines to grow by accessing Parker's well-established international
platform and thereby further enhance shareholder value."

         Superior provides oil tool rentals, well plug and abandonment
services, and other specialized products and services to oil companies
operating in the Gulf of Mexico and Gulf Coast land regions.  Superior
is headquartered in Harvey, La.

         In 1996, Parker acquired Louisiana-based Quail Tools and barge
drilling contractor Mallard Bay Drilling. The same year Parker acquired the
assets of Bolifor, S.A., Bolivia's largest land drilling contractor,

and in 1997, Parker expanded its Gulf of Mexico presence with the purchase of
Hercules Offshore Corporation.

         Parker is an international provider of offshore and on-land drilling
services. The company's wide variety of equipment includes shallow water jackups
and offshore platform rigs, transition zone barge rigs and land rigs which
currently operate in 14 countries. Tulsa-based Parker, founded in 1934, has
operated in 49 nations.

                  This news release contains forward-looking statements under
the Private Securities Litigation Reform Act of 1995. Although the company
believes that these statements are based upon reasonable assumptions, the
company can give no assurance that its expectations will be achieved. Actual
results may differ materially due to various risks and uncertainties which are
outside the control of the company, such as market prices of oil and gas, the
volatility of such prices, governmental regulation and trade restrictions,
worldwide economic activity and political stability in major oil producing
areas.
